The door 118, which opens / closes the hole for loading the laundry, can be rotated Available on front cover 112.

Glass 118a may be provided on door 118 so that the user can observe the laundry inside the drum 134 outside the washing machine 100. The glass 118a may be convex and the front end of the glass 118a may protrude up to the inside of the drum 134 in a state in which the door 118 is closed.

The detergent drawer 114 is used to add additives, such as a pre-wash or a main wash detergent, fabric softener and bleach. It is envisioned that the detergent drawer 114 can be removed from the skin 110.

The tank 132 can be suspended by means of a spring so that vibration generated by the rotation of the drum 134 can be absorbed. The damper 134 can additionally be provided with a damper supporting the tank 132 from the bottom of the tank 132.

A plurality of holes are formed in the drum 134 so that water can flow between the tub 132 and the drum 134 through them. One or more elevators 134a may be provided along the inner peripheral surface of the drum 134 so that the laundry can be lifted and then thrown in accordance with the rotation of the drum 134.

Drum 134 is not positioned completely horizontally, but is positioned with a pre-determined tilt so that the rear of drum 134 is below a horizontal level.

A motor providing a driving force for turning the drum 134 may be provided for the drum 134. The engine can be classified as either a direct drive type or an indirect drive type according to the method of transmitting the driving force provided by the engine to the drum 134. In the direct drive type, the rotary the motor shaft is directly attached to the drum 134, and the rotating motor shaft and the center of the drum 134 are aligned coaxially. The washing machine 100 in accordance with this embodiment is based on a direct drive type. Although the drum 134 is rotated by an engine 141 provided in the space between the rear of the tub 132 and the housing 111, the present invention is not necessarily limited thereto, and it is obvious that the indirect drive type described above is possible.

In the indirect drive type, the drum 134 is rotated using power transmission means, such as a belt or block, to transmit the driving force provided by the engine. In the indirect drive type, the rotating shaft of the engine and the center of the drum 134 are not necessarily aligned coaxially.

A sealing device 120 is provided between the casing 110 and the tank 132. The sealing device 120 prevents leakage of water stored in the tank 132 between the tank 132 and the casing 110. One side of the sealing device 120 is connected to the casing 110, and the other end of the sealing device 120 is connected to the tank 132 along the periphery of the open front of the tank 132. The sealing device 120 elastically folds / unfolds in accordance with the vibration of the tank 132, thereby absorbing the vibration.

The sealing device 120 can be created from a deformable or flexible material that has little elasticity, and can be formed using natural rubber or synthetic resin.

The washing machine 100 is connected to a hot water source HW for supplying hot water and a cold water source CW for supplying cold water, respectively, through the hot water hose 115a and the cold water hose 115b, and the water flowing into the washing machine 100 through the hot water hose 115a and the hose Cold water 115b is supplied to a detergent drawer 114, a steam generator 139 and / or a spiral nozzle 50 and 60 under proper control of the water supply unit 136.

In particular, the water supplied through the cold water hose 115b can be supplied to the detergent drawer, steam generator 139 and / or spiral nozzle 50 and 60 through the first to fourth water supply valves 136a to 136d.

A drawer 114 for detergents is placed inside the housing 117 of the drawer for detergents. The detergent drawer housing 117 is connected to the tub 132 through a corrugated water supply tube 133. The water supplied through the water supply unit 136 is mixed with additives through the detergent drawer 114 and then moved inside the tank 132 through the corrugated water supply tube 133 connected to the detergent drawer body 117.

Washing detergent, fabric softener, bleach, etc. can be used as additives placed in the box 114 for detergents. A plurality of receiving spaces may be provided in the detergent drawer 114 so as not to mix the additives with each other, but to be separately placed in the detergent drawer 114.

The first, second, and third water hoses 131a, 131b, and 131c are used to supply water to the detergent drawer 114, and in this order correspond to the divided spaces formed in the detergent drawer 114 to add additives. The first, second and third water supply valves 136a, 136b and 136c respectively control the first, second and third water supply hoses 131a, 131b and 131c.

The steam generator 139 is a device that generates steam by heating water. Water is supplied to a steam generator 139 through a fourth water supply hose 136d. The steam generated in the steam generator 139 is supplied to the steam nozzle 70 and 80 through a hose 137 for supplying steam.

Water supplied through the hot water hose 115a flows into the detergent drawer 114 through the fifth water supply hose 131e, and a hot water valve 136e for controlling the fifth water supply hose 131e may be provided for the fifth water supply hose 131e.

Meanwhile, the dispenser 119 can be connected to the third water supply hose 131c. In this case, the water passing through the dispenser 119 is distributed into the sixth water supply hose 131f and the seventh water supply hose 131g, and thus, water is sprayed through the spiral nozzle 50 and 60 and the water is supplied through the detergent drawer 114. Thus, it is possible to wet the laundry in the drum 134 effectively. In particular, the laundry can be sufficiently moistened using only a small amount of water compared to the standard method carried out only when the water is supplied through the detergent drawer 114.

Pump 148 is used to drain water discharged from tank 132 through corrugated drain pipe 147 outward through drain hose 149 or to supply pressurized water to a pair of circulation hoses 151 and 152, respectively connected to the first and second nozzles 160 and 170 of the sealing device. Therefore, if pump 148 is operating, water is sprayed through nozzles 160 and 170 of the sealing device. In this embodiment, the pump 148 has both a drainage pump function and a circulation pump function. However, it is obvious that a drainage pump and a circulation pump can be provided separately.

The water supplied under pressure by the pump 148 is simultaneously supplied to the first and second circulation hoses 151 and 152. Thus, the water is simultaneously sprayed in the direction of the laundry from the first and second nozzles 160 and 170 of the sealing device.

Pump 148 may include an impeller rotated by motor 141 and a pump housing in which the impeller is located. The first and second outlet ports 148a and 148b may be provided in the pump housing, through which the pressurized water is discharged by rotation of the impeller. The first circulation hose 151 can be connected to the first outlet port 148a and the second circulation hose 152 can be connected to the second outlet port 148b. Since water is discharged from the pump 148 through two independent ports 148a and 148b, water can be supplied under the same water pressure to the circulation hoses 151 and 152.

In FIG. 11 schematically illustrates a diagram in which washing water is sprayed through nozzles of a sealing device. With reference to FIG. 11, the laundry 10 is re-lifted by the lifter 134a and then dropped during the rotation of the drum 134. In this case, the first and second nozzles 160 and 170 of the sealing device simultaneously spray water in the direction of the falling laundry 10. This technique has the advantage that that water can be uniformly sprayed in the direction of the laundry 10, regardless of the direction of rotation of the drum 134.

However, a dispenser may be provided between the pump 148 and the circulation hoses 151 and 152 so that water is sprayed alternately through a pair of nozzles 160 and 170 of the sealing device. In this case, water can be selectively sprayed through the first or second nozzle of the sealing device 160 or 170 in accordance with the direction of rotation of the drum 134, under proper control of the distributor.

A dryer box 138 is used to direct the movement of air so as to let air in the tank 132 out of the tank 132 and then again directed into the tank 132. The dryer box 138 may include a first drying box 138a and a second drying box 138b.

The first drying box 138a directs air from the tank 132 to the air blower 142. The side of the first drying box 138a with which air flows into the first drying box 138a is connected to the tank 132, and the side of the first drying box 138a with which air is discharged from the first drying box 138a connected to air blower 142.

The second drying box 138b directs the air pumped by the air blower 142 into the tank 132. The side of the second drying box 138b with which air flows into the second drying box 138b is connected to the air blower 142, and the side of the second drying box 138b with which the air is discharged from the second drying box 138b, connected to the tank 132. In this embodiment, a sealing part 120 is provided in the sealing device 120, to which the second drying box 138b is connected. A duct-connected portion 129 allows the inside of the drum 134 and the second drying duct 138b to communicate with each other.

A part 125 connected to the nozzle block, which has a nozzle block 161 connected to it, can be formed on the top of the sealing device 120. The part 125 connected to the nozzle block can comprise a first mounting hole 125a through which the spiral flow generating tube 60 is inserted and connected to a part 125 connecting to the nozzle block, and a second mounting hole 125b through which the steam inlet pipe 70 is inserted and connected to the nozzle block connecting part 125.

The air blower 142 pumps air to be circulated through the drying duct 138. The air blower 142 may include a fan of a suitable type in accordance with the arrangement relationship between the first and second drying ducts 138a and 138b. An air blower in accordance with this embodiment comprises a centrifugal fan. The centrifugal fan is suitable for discharging air sucked from the bottom of the centrifugal fan through the first drying box 138a into the second drying box 138b, connected to the centrifugal fan in the lateral direction.

Meanwhile, a drying heater (not shown) may be provided in order to remove moisture from the air flowing through the drying duct 138. The drying heater may be located inside the drying duct 138, in particular inside the second drying duct 138b through which the air supplied under pressure by air blower 142.

The control panel 180 may include a mode selection unit 182 for receiving mode selection input from a user, an input / output unit 184 that receives various types of control commands and displays the operating status of the washing machine 100. The control panel 180 is described in detail below with reference to FIG. 12.

The anti-separation protrusions 121 can be formed on the sealing device 120. Here, the anti-separation protrusions 121 prevent the laundry from separating from the drum 134 by rotating the drum 134 and then falling between the sealing device 120 and the casing 110, in particular the front cover 112, or to prevent the laundry from falling out washing outside of the washing machine 100 when the door 118 is opened after completion of the washing. The anti-separation protrusions 121 are formed to protrude in the direction of the laundry loading hole from the inner peripheral surface of the sealing device 120.

Prevention of separation protrusions 121 can be formed in a variety of positions. In particular, the anti-separation protrusions 121 can be appropriately formed at positions symmetrical to each other with respect to the vertical center line H of the sealing device 120.

The sealing device 120 may comprise a plurality of nozzles 160 and 170 of the sealing device spraying water inside the drum 134, and a plurality of connectors 123 and 124 supplying water to the respective nozzles of the sealing device.

Although this embodiment has described that water is sprayed by two nozzles 160 and 170 of a sealing device, the present invention is not limited thereto. That is, two or more nozzles of the sealing device may be provided in order to spray water inside the drum 134 in a variety of directions.

The nozzles 160 and 170 of the sealing device can be integrally formed with the sealing device 120. For example, the nozzles 160 and 170 of the sealing device and the sealing device 120 can be formed integrally by injection molding using synthetic resin.

The nozzles 160 and 170 of the sealing device can be formed to protrude from the inner peripheral surface of the sealing device 120, and the connectors 123 and 124, respectively connected to the circulation hoses 151 and 152, can be formed on the outer peripheral surface of the sealing device 120. The connectors 123 and 124 may include a first connector 123 for connecting the first nozzle of the sealing device 160 and the first circulation hose 151 and a second connector 124 for connecting the second rsunki sealing device 170 and the second circulation hose 152.

More specifically, the first or second nozzle 160 and 170 of the sealing device atomizes the water inside the drum 134. Preferably, the water sprayed through the nozzles 160 and 170 of the sealing device reaches not only the inner peripheral surface of the drum 134, but also the rear wall 134b of the drum 134. In particular, in the case where a small amount of laundry is placed inside the drum 134, the laundry is collected next to the rear wall 134b of the drum 134 due to rotation or inclination of the drum 134. In this case, the laundry cannot be moistened with water sprayed from nozzles 160 and 170 of the sealing device.

The water sprayed from the first nozzle of the sealing device 160 and the water sprayed from the second nozzle of the sealing device 170 preferably intersect with each other at least once before reaching the rear wall 134b of the drum 134. The first and second nozzles 160 and 170 of the sealing device are designed so that the water sprayed from the first nozzle of the sealing device 160 and the water sprayed from the second nozzle of the sealing device 170 intersect with each other, and thus the sprayed water or, it can reach a wider area, even though interference occurs to some extent, instead of the water sprayed from the first nozzle of the sealing device 160 and the water sprayed from the second nozzle of the sealing device 170 never intersecting with another, and therefore, in the drum to some extent or more, there was a region that the water does not reach.

Meanwhile, cargo may be provided on the tank 132. The load is a heavy body that has a significant mass, and the stability of the tank 132 can be maintained by the inertia created by the load, even when the drum 132. The load can be provided using a variety of weights on the front 132b of the tank 132. In the washing machine 100 in accordance with this embodiment, the two upper weights 146, horizontally symmetrical to each other with respect to the vertical center line H, are provided above the horizontal center line C of the tank 132, and the lower load 144 pr delivered centered below the horizontal center line C of the tank 132. In order to avoid grazing the lower load 144 first and second connectors 123 and 124 is preferably a suitably on both sides of the lower weight of 144.

The first and second nozzles 160 and 170 can be arranged symmetrically to each other with respect to the vertical center line H passing through the center of the sealing device 120 so as to evenly spray the washing water inside the drum 134.

In particular, the first and second nozzles 160 and 170 of the sealing device can be provided on both sides of the lower part of the sealing device 120 to the extent that do not exceed half the height of the sealing device 120. In this case, the first nozzle of the sealing device 160 sprays water upward towards the inner parts of the drum 134 from the lower left of the sealing device, and a second nozzle of the sealing device 170 sprays water upward towards the inside of the drum 134 from the lower left part of the sealing device 120 (see. FIG. 11). Laundry for washing, which is lifted by means of a hoist 134a and which then falls, passes through the spray area formed by the first and second nozzles 160 and 170 of the sealing device. The nozzles 160 and 170 of the sealing device spray water upward in the direction of the falling laundry so that the sprayed water hits the laundry strongly. Thus, the laundry is bent and stretched, thereby increasing the washing efficiency of the laundry.

In FIG. 6 illustrates a structure in which the circulation hoses 151 and 152 are fixed. With reference to FIG. 6, the holder 135 for fixing the circulation hose 151 or 152 can be formed on the tank 132. The holder 135 may include a pair of locking ribs 135a and 135b protruding from the front portion 132b of the tank 132, and the circulation hoses 151 or 152 are inserted and fixed between the pair of locking ribs 135a and 135b.

When considering the structure in which the pump 148 is located below the tank 132, and the connectors 123 and 124 protrude from the sealing device 120 in an approximately horizontal direction, the fixing ribs 135a and 135b are preferably curved.

A clip 154 is used to fix the circulation hose 151 or 152 to the tank 132, and it clamps the circulation hose 151 or 152. The protrusion 156, which has a clip 154, fixed and attached to it, can be formed on the lower outer part of the tank 132.

Essentially, in the structure in which the circulation hose 151 or 152 is fixed to the tank 132 by means of the fixing ribs 135a and 135b and the clamp 154, the circulation hose 151 or 152 moves with the tank 132 as a whole. Thus, although vibration is generated during the operation of the washing machine 100, it is possible to reduce the tension applied to the circulation hose 151 or 152, thereby reducing the disconnection of the circulation hose 151 or 152.

Using the simple process of pre-installing the circulation hose 151 or 152 into the holder 135 and then snapping the clamp 154 onto the circulation hose 151 or 152, the circulation hose 151 or 152 can be fixed to the tank 132, thereby simplifying the assembly process.

Meanwhile, the circulation hose 151 or 152 can be connected to the connector 123 or 124 by means of the connecting pipe 157. The circulation hoses 151 and 152 can be made of flexible material, and the connector 123 can be integrated with the flexible sealing device 120. The connecting pipe 157 is formed of material relatively harder than the connectors 123, and both ends of the connecting pipe 157 are respectively inserted into the circulation hose 151 or 152 and the connector 123 or 124, so that it is possible to further facilitate the connection ix between the circulation hose 151 and the connector 152 or 123 or 124.

In order to further guarantee the connection between the circulation hose 151 or 152 and the connector 123 or 124 through the connecting pipe 157, a clip 158a is additionally provided for clamping one end of the circulation hose 151 or 152 into which the connecting pipe 157 is inserted, and a clamp 158b for clamping one end a connector 123 or 124 into which the connecting pipe 157 is inserted.

In FIG. 7, the nozzle block 161 is illustrated. FIG. 8A is a partial cross-sectional view of the spiral nozzle 50 and 60 of FIG. 7. In FIG. 8B is a plan view of the nozzle assembly 161 of FIG. 7 when they look at her from top to bottom.

With reference to FIG. 7, 8A and 8B, the nozzle block 161 may be provided at the top of the sealing device 120. The nozzle block 161 comprises a spiral nozzle through which water is sprayed inside the drum 134, and a steam nozzle through which steam is sprayed inside the drum 134. Obviously, the spiral and steam nozzles can be formed as separate components that are independent of each other. The nozzle block 161 can be formed as an assembly of a spiral flow generating tube 60, nozzle cover 190 and a steam inlet tube 70. Hereinafter, a component 50 and 60 that generates a spiral flow and sprays inside the drum 134 is referred to as a spiral nozzle, and the component 70 and 80, which sprays steam inside the drum 134, are referred to as a steam nozzle.

The spiral nozzle 50 and 60 converts the water supplied through the water supply hoses 131c and 131f into a spiral flow and spray inside the drum 134. The spiral nozzle 50 and 60 comprises a spiral flow generating tube 60 connected to a sixth water supply hose 131f and a cap a spiral nozzle 50 spraying water flowing through a spiral flow-generating tube 60 inside the drum 134.

The cap of the spiral nozzle 50 includes an outlet 52h discharging water supplied through the spiral flow-generating tube 60 and a collision surface 55 formed on the path along which the water discharged through the outlet 52h so that the water flow can be distributed causing a collision in the direction of the water.

Since the water sprayed through the outlet 52h is distributed while it hits the collision surface 55 again, water can be uniformly sprayed inside the drum 134 even when the water pressure is low.

More specifically, the cover of the spiral nozzle 50 provides a predetermined space in which water is contained within it, and the predetermined space communicates with the external space through the outlet 52h. Water discharged through the outlet 52h moves along the outlet 52, which flows, thereby forming a downward slope, and then spreads, while striking the collision surface 55 formed at the finish end of the outlet 52. Therefore, the surface 55 for the collision does not run parallel to the direction of water propagation through the outlet 52, but is preferably formed at a predetermined angle to the outlet 52 so that water flowing through the outlet 52 was spread through surface 55 for collision.

The spiral flow-generating tube 60 comprises a flow-forming tube 61 connected to a sixth water supply hose 131 to form a water flow channel within it, and at least one blade for guiding the water to advance during rotation in a certain direction in the tube 61 forming the flow channels. In the case where a plurality of vanes are provided in the blade, the space in the flow channel forming tube 61 is divided into spaces by the respective vanes, and the vanes form the flow channels in order to independently direct the water. Hereinafter, as an example, a case is described in which the first and second vanes 63 and 65 are rotated in the same direction.

A blade shaft 62 is formed in the center of the flow channel forming the tube 61, and the blades 63 and 65 are formed, while connecting the inner peripheral surface of the flow channel forming the tube 61 and the blade shaft 62. The blades 63 and 65 extend in the direction of the length of the blade shaft and can rotate along the periphery of the blade shaft 62. The boundary between the inner end of the blade 63 or 65 and the shaft 62 of the blade and the boundary between the outer end of the blade 63 or 65 and the forming flow channel of the tube 61 forms a pair of spiral curves parallel to each other.

The water is turned into a spiral stream, while directing along the blades 63 and 65 into the tube 61 forming the flow channels. The water converted into a spiral stream is uniformly sprayed inside the drum 134 by its rotation force.

The shaft 62 of the blade does not necessarily go in accordance with the full length of the channel forming the flow channels of the tube 61, but goes to a shorter distance along the shaft 62 of the blade of the blade than the full length of the channel forming the flows of the tubes 61. In this case, the finish end 63b or 65b of the blades 63 or 65 wherein the rotation of the water in the flow channel forming tube 61 ends, preferably goes up to the end portion of the flow forming channel 61.

The first and second blades 63 and 65 are preferably formed so that they do not have a part in which the first and second blades 63 and 65 overlap with each other. Therefore, the relative position between the start end 63a of the first blade 63 and the finish end 65b of the second blade 65 is associated with that between the finish end 63b of the first blade 63 and the start end 65a of the second blade 65. The rotation angle from the start end 63a to the finish end 63b of the first blade 63 also associated with that from the start end 65a to the finish end 65b of the second blade 65.

For example, if the first blade 63 is rotated through an angle x while it goes from the start end 63a to the finish end 63b, the start and finish ends 65a and 65b of the second blade 65 are necessarily formed in a certain area except for the area in which the first blade 63 is formed on plane, as seen along the blade shaft 62. The second blade 65 is rotated within the range where the angle, with the exception of the rotation angle of the first blade 63, i.e. the angle (360-x) degrees, is set to the maximum value, while it goes from the start end 65a to the finish end 65b.

That is, if the structure of any one of the first and second vanes 63 and 65 is determined to the extent where the first and second vanes 63 and 65 do not overlap, variables such as the start end, finish end, length of extension and maximum rotation angle the other is limited to predefined limits.

Spiral flow-generating tube 60 can be formed by injection molding. In this case, careful design is necessary in order to easily remove from the mold, taking into account the structure of the blades 63 and 65 formed in the spiral flow-generating tube 60. The first and second blades 63 and 65 do not necessarily overlap each other, as described above. In addition, when looking at the first and second blades 63 and 65 along the length direction of the blade shaft 62, a predetermined interval is preferably formed between the start end 63a of the first blade 63 and the finish end 65b of the second blade 65. Similarly, a predefined interval is preferably formed between the finish the end 63b of the first blade 63 and the starting end 65a of the second blade 65.

Meanwhile, since it is sufficient that the movement of the rod is possible during injection molding, the interval between the start end 63a of the first blade 63 and the finish end 65b of the second blade 65 or the interval between the finish end 63b of the first blade 63 and the start end 65a of the second blade 65 may be small . The length of the extension or the angle of rotation of the first or second blade 63 or 65, which is lost due to the interval, are very small, which can be neglected.

In the range where the first and second vanes 63 and 65 do not overlap, the first vanes 63 can essentially be rotated 180 degrees as they move from the initial end 63a to the finish end 63b so as to have a maximum length of the first blade 63, and the second blade 65 can essentially be rotated 180 degrees as they move from the start end 65a to the finish end 65b so as to have a maximum extension length of the second blade 65 (strictly speaking, there is a loss angle due to the interval between the initial m the end 63a of the first blade 63 and the finish end 65b of the second blade 65 or the interval between the finish end 63b of the first blade 63 and the start end 65a of the second blade 65, and thus the rotation angle of each blade is less than 180 degrees). In this case, the start end 63a of the first blade 63 and the start end 65a of the second blade 65 are located symmetrically to each other around the blade shaft 62, and the finish end 63b of the first blade 63 and the finish end 65b of the second blade 65 are also located symmetrically to each other around the blade shaft 62.

The finish end 63b or 65b of each blade forms a predetermined angle with an outlet port 62h near the blade shaft 62. For example, in FIG. 8B, the angle formed by the outlet 52h of the cover of the spiral nozzle 50 and the starting end 63a of the first blade 63 near the blade shaft 62 is represented as an angle (45 degrees) between A1 and A2. This indicates that the angle formed by the outlet 52h and the finish end 63b of the first blade 63 is 135 degrees.

The collision surface 55 may include a curved surface portion 53 in order to direct the water striking the collision surface 55 to spray down, and the first and second descending guide surfaces 53a and 53b, which go so as to have a gradient on both sides thereof . Here, the first and second descending guide surfaces 53a and 53b can go so as to have different gradients.

In particular, the gradients of the first and second downward guiding surfaces 53a and 53b can be determined taking into account the position of the spiral nozzle 50 and 60 on the sealing device 120. That is, in the case where the spiral nozzle 50 and 60 is not located on the vertical center line H of the sealing device 120, but is located offset to one side, the gradients of the first and second descending guide surfaces 53a and 53b can be set different from each other so that the water can be uniformly sprayed inside the drum 134. Pre the preferably downward guiding surface 53a, which directs the water sprayed within the area related to the spiral nozzle 50 and 60 near the vertical center line H, has a larger gradient than the other downward guiding surface 53b. In this embodiment described with reference to FIG. 4 and 5, the steam nozzle 70 and 80 are aligned with the vertical center line H of the sealing device 120. Therefore, the spiral nozzle 50 and 60 is located in the right region near the vertical center line H. In this case, the gradient of the first descending guide surface 53a directing the largest part of the water sprayed into the right region is formed larger than that of the second descending guide surface 53b.

Meanwhile, the reason why the first and second downward guiding surfaces 53a and 53b are formed so that they have different gradients is because, although the spiral nozzle 50 and 60 are located in a position offset to one side from the vertical the center line H, water can be sprayed while avoiding the separation of the protrusion 121, suitably formed in positions symmetrical to each other about the vertical center line H. Since the spiral nozzle 50 and 60 are not located on the top ical center line H, the relative position between the spiral nozzle 50 and 60 and any one anti-separation protrusion 121 is different from that between the spiral nozzle 50 and 60 and the other anti-separation protrusion 121. Therefore, the water atomization patterns through the first and second downstream the guiding surfaces 53a and 53b are necessarily directed perfectly apart to spray water, while avoiding both, preventing the protrusions 121 from separating. For this purpose, a plan for differentiating ation first downward gradient of the guide surface 53a from that of the second downlink guide surface 53b.

Meanwhile, a barrier 56 for restricting the lateral movement of water flowing along each guide surface can be formed on at least one of the first and second descending guide surfaces 53a and 53b. In particular, the barrier 56 can be formed on any one of the first and second downward guiding surfaces 53a and 53b, taking into account the direction of rotation of the water in the spiral flow generating tube 60. That is, since the water in the spiral flow generating tube 60 is rotated by means of vanes 63 and 65, the flow rate of water directed along the first descending guide surface 53a and the flow rate of water directed along the second descending guide surface 53b have different values from each other, and may znikat problem regarding the fact that water is distributed to sealing device 120 on the side where water is directed at a relatively high flow rate of the first and second downstream guide surfaces 53a and 53b. Therefore, the barrier 56 can be formed on at least one of the first and second descending guide surfaces 53a and 53b. Preferably, the barrier 56 is formed on the side where water with a higher flow rate is directed along the first and second descending guide surfaces 53a and 53b, taking into account the direction of rotation of the vanes 63 and 65.

With reference to FIG. 8A in this embodiment, the rotation of the water in the spiral flow-generating tube 60 is clockwise (when viewed from top to bottom in FIG. 7), and accordingly, water at a high flow rate is guided along the second descending guide surface 53b, and not along the first downward guide surface 53a. Accordingly, a barrier 56 is formed on the second downward guide surface 53b.

As described above, the first downward guide surface 53a is formed so that it has a higher gradient than the second downward guide surface 53b, and a barrier 56 is formed on the second downward guide surface 53b. However, which gradient from the first and second descending guide surfaces 53a and 53b is formed more than the other, and which one of the first and second descending guide surfaces 53a and 53b should form a barrier 56, is preferably determined by taking various variables into account. The variables may be the position of the spiral nozzle 50 and 60 on the sealing device, the position preventing separation of the protrusion 121, the angle of spraying water, under which the water can be sprayed, while avoiding the glass 118a of the door protruding inside the drum 134, etc.

The steam nozzle 70 and 80 is used to spray the steam supplied through the hose 137 for supplying steam to the inside of the drum 134. The steam nozzle 70 and 80 may include a steam inlet pipe 70 attached to the sealing device 120 and connected to the steam supply hose 137, and a steam nozzle cover 80, which has a vapor spray opening 82h, through which steam flowing through the steam inlet pipe 70 is sprayed inside the drum 134. The steam nozzle cover 80 and the spiral nozzle cover 50 are formed in a single body and form to a little piece of 190 nozzles. In this case, the nozzle block 161 can be made in the form of an assembly obtained by joining as a unit a spiral flow-generating tube 60, a steam inlet tube 70 and a nozzle cover 190, which are respectively obtained by injection molding using separate elements.

In FIG. 9 illustrates the nozzle of a sealing device. In FIG. 10 is a perspective view taken along line D-D in FIG. 9. In FIG. 11 schematically illustrates a scheme in which washing water is sprayed through nozzles of a sealing device.

With reference to FIG. 9-11, the sealing device 120 may include a part 128 connected to the casing connected to the casing 110, in particular a front cover 112, a part 126 connected to the tank, connected to the tank 132, and a folding part 127, folding / unfolding due to the vibration of the tank 132 .

The first and second nozzles 160 and 170 of the sealing device are arranged symmetrically to each other with respect to the vertical center line H on the sealing device 120, but the structures of the first and second nozzles 160 and 170 of the sealing device are substantially identical to each other. Hereinafter, a second nozzle of a sealing device 170 is advantageously described herein.

The nozzle of the sealing device 170 comprises a spray guide surface 171 that directs the water to be sprayed upward in the direction of the interior of the drum 134 by changing the direction of propagation of water flowing through the inlet 177a in communication with the connector 124 and a plurality of protrusions 172 located along the width direction of the guide spraying the surface 171 on the guide spraying the surface 171.

The width of the spray guide surface 171 gradually increases along the direction of water distribution. In FIG. 9, the spray guide surface 171 at the initial end, where water flowing from the inlet 177a starts to be guided, has a width D1, and the spray guide surface 171 at the finish end where the water is sprayed directed along the spray guide of the surface 171, while separating, has a width D2 (D1 <D2).

The protrusions 172 are preferably formed adjacent to the finish end of the spray guide surface 171. The width of the spray guide surface 171 at the finish end of the spray guide surface 171 can be maximized.

The nozzle of the sealing device 170 may include an inlet forming surface 177, which has an inlet 177a through which water flows in, communicating with the connector 124, and a pair of surfaces narrowing the flow channel 174 to increase the flow rate of water flowing towards the finish end of the spray guide surface 171, by restricting the lateral flow of water discharged from the inlet 177a to the spray guide surface 171. Water passing through the inlet 177a is directed along the flow channel, a conventional spray guide surface 171 and a pair of flow channel narrowing surfaces 174 appropriately formed on both sides of the spray guide surface 171.

The spacing surface 173 is used to make it possible to separate the spray guide surface 171 from the inlet forming surface 177 in which the inlet 177a is formed. In FIG. 9, the initial end of the spray guide surface 171 is separated by the interval corresponding to the height W of the inlet forming surface 177 from the inlet forming surface 177. Since the spray guide surface 171 is separated from the inlet forming surface 177, it is possible to facilitate the installation and removal of the injection mold to form the inlet 177a during injection molding.

The lateral flow of water flowing through the connector 124 is limited by the channel narrowing the flow surface 174 relative to when the water is discharged from the inlet 177a. Thus, water flowing along the spray guide surface 171 can be in a quick and compressed state. Water can be sprayed evenly through the nozzle of the sealing device 170, even when the water pressure is low.

 More specifically, the spray guide surface 171 is formed so that a gradual increase in its width occurs from the start end to the finish end. And forming the inlet surface 177 is formed so that there is a gradual increase in its width from the initial end to the finish end. Assuming that there is an imaginary connecting surface formed in the form of one plane that connects both lateral sides of the spray guide surface 171 and forming the inlet surface 177, the protruding portion can be formed so that it protrudes into the nozzle of the sealing device 170 from the imaginary connecting surface. In this case, the lateral flow of water is limited in accordance with the length of the inner width of the nozzle of the sealing device, reduced by the protruding part, and accordingly there is an increase in the flow rate of water. Here, as can be seen with reference to FIG. 9 and 10, the nozzle of the sealing device 170 may have at least two surfaces 174 and 175 protruding inward from an imaginary connecting surface so as to form a protruding portion. Among these surfaces, a surface extending from the initial end of the spray guide surface 171 can be defined as a narrowing of the flow channel surface 174, and other surfaces 175 are surfaces dependently formed to connect between the narrowing of the flow channel surface 174 and the spray guide surface 171 or forming inlet surface 177.

Meanwhile, the narrowing of the flow channel surface 174 can be geometrically defined between two boundaries extending from the spacing surface 173. The first border 174a is a border that extends, while limiting the width of the spray guide surface 171 from the point at which the spacing surface 173 and the spraying guide surface 171 meet each other, and the second boundary 174b is the border that goes, while gradually converging with the first border 174a, from the point at which the forming erval surface 173 and forming an inlet surface 177 meet each other. In this case, the first boundary 174a may extend from the initial end of the spray guide surface 171.

Meanwhile, the nozzle of the sealing device 170 protrudes from the inner part of the sealing device 120. The outer curved surface portions 176 can be appropriately formed at both outer ends of the nozzle of the sealing device 170 in order to minimize damage to the laundry when the laundry is rotated and hit the nozzle a sealing device 170. The outer curved portion 176 of the surface may have the smallest curvature in the portion where the outer curved portion 176 of the surface meets I am with the inner peripheral surface of the sealing device 120.

In the sealing device 120, a nozzle bypassing portion 127a may be provided, forming a predetermined interval t between the bypassing nozzle part 127a and the nozzle of the sealing device 170, while bypassing the nozzles of the sealing device 170. Although the sealing device 120 is deformed when the tank 132 is vibrated, it is possible to prevent deformation caused by compression between the sealing device 120 and the nozzle of the sealing device 170, and changing the spray direction of the nozzle the sealing device 170 due to deformation through the buffer effect due to the interval t formed between the bypassing nozzle portion 127a and the nozzle of the sealing device 170.

Meanwhile, since there is a change in the propagation direction of the water flowing through the inlet 177a, upon impact on the spray guide surface 171, the water is directed so that water is compressed, while applying a predetermined positive pressure to the spray guide on the surface 171. Thus, spraying water through the nozzle of the sealing device 170 has the form of an aqueous film, basically having a surprisingly small thickness compared to its width.

However, when water passes through the protrusions 172 formed on the spray guide surface 171, the thickness of the aqueous film is relatively large between the protrusions 172, and the thickness of the aqueous film is relatively small in the peak portion of the protrusion 172. Thus, the final water spray pattern has a shape in which a plurality of basic spray streams with high water flow rates are connected by a thin water film due to the difference in thickness between the water films. Water sprayed according to this scheme can remove the contaminant adhering to the laundry using a strong blow through the main spray stream, and the laundry is bent and stretched, thereby increasing the washing efficiency. In addition, the area of spraying water can be sufficiently provided by means of an aqueous film.

In FIG. 12 illustrates a control panel according to one embodiment of the present invention.

The control panel 180 is located on the front upper part of the casing 110. The control panel 180 comprises a mode selection unit 182 that allows the user to select a washing mode, a mode display unit 181 that displays selectable washing modes, and an input / output unit 184 that receives various control commands entered by the user, such as the operating time for each cycle and reservation, and displays information about the mode in accordance with the choice of the mode by the user, information in accordance with another command entered by the field zovatelem and operating state during operation of the washing machine.

The mode selection unit 182 receives a user selectable washing mode. The mode selection unit 182 can be formed using various types of input devices, such as a button and a touch-sensitive screen. In this embodiment, the mode selection unit 182 is a knob.

The washing mode is used to determine the stages of each cycle throughout the entire washing process in accordance with the type or function of the laundry. In this embodiment, the washing mode is divided into the COTTON / NORMAL mode, the TOWEL mode, the CAPACITY / LARGE mode, the BRIGHT WHITES mode, the SANITARY mode, the ALLERGIENE mode, the TANK CLEANING mode, the AMPLIFIED mode, the MANDLE WASH mode, the MANUAL WIPE / WASH mode / QUICK WASH mode and LOAD mode.

Each mode can be divided into a washing cycle, a rinse cycle, a water removal cycle, a complex cycle, etc. The stage of water supply, washing, rinsing, drainage, water removal, drying, etc., is carried out in each cycle.

The mode display unit 181 selects washing modes that can be selected by the user through the mode selector 182. The mode display unit 181 can be integrally formed with the mode selection unit 182 so as to be implemented as a touch-sensitive screen. In this embodiment, the mode display unit 181 is displayed by printing around a pen-shaped mode selection unit 182.

In this embodiment, the COTTON / NORMAL mode, the TOWEL mode, the VOLUME / LARGE mode, the BRIGHT WHITES mode, the SANITARY mode, the ALLERGIENE mode, the TANK CLEANING mode, the ENHANCED mode, the MUFFLE mode, the MANUAL WASH / WOOL mode, the DELIVERY mode, The LOAD mode is displayed in the mode display unit 181.

The input / output unit 184 receives various types of commands inputted by the user, and information of various types is displayed in the input / output unit 184. The input / output unit 184 may be implemented with a plurality of buttons and with a screen, or may be implemented as a touch sensitive screen. The I / O unit 184 includes a washing time display unit 186 for displaying an expected washing time, and a turbo-washing button 185 for setting a turbo-washing in which the laundry is washed by circulating water contained in the tub 132 and spraying water inside the drum 134 through nozzles 160 and 170 of the sealing device, and / or a turbo-wash for performing a turbo rinse, in which the laundry is rinsed by circulating water contained in the tank 132, and spraying water inside the drum 134 through the nozzles 1 60 and 170 of a sealing device, or turbo rinse, in which laundry is rinsed by spraying water inside the drum 134 through a spiral nozzle 50 and 60 to turn the water into a spiral stream.

The washing time display unit 186 displays the expected washing time before the washing starts. The washing time display unit 186 displays the expected washing time in accordance with the washing mode inputted by the mode selection unit 182. If the turbo wash is set by the turbo wash button 185, the wash time display unit 186 displays the expected wash time, which is changed in accordance with the turbo wash. The washing time display unit 186 displays the remaining washing time during the washing.

The turbo-wash button 185 is a button through which the user sets a turbo-wash. If the user presses the turbo-wash button 185, a turbo-wash is set. Then, if the user presses the turbo wash button 185 again, the turbo wash is canceled in order to set the total wash. If a turbo wash is set, the turbo wash button 185 emits light in order to indicate that a turbo wash is set.

If a turbo wash is specified, the washing time display unit 186 displays the expected washing time, which is changed in accordance with the turbo wash. If turbo-washing is carried out, the expected washing time is reduced in the same washing mode. Thus, if a turbo wash is set, the expected wash time displayed in the washing time display unit 186 is reduced. If the total wash is set due to the cancellation of the turbo wash, the expected wash time displayed in the washing time display unit 186 is increased.

A turbo wash is used to carry out a turbo wash in which laundry is washed by rotating the drum 134, circulating water mixed with the washing detergent, and then spraying water inside the drum 134 through nozzles 160 and 170 of the sealing device in the selected mode washing and / or turbo rinsing in the laundry is rinsed by rotating the drum 134, circulating the water mixed with the rinse detergent, and then spraying the water inside the drum 134 through nozzles 160 and 170 of the sealing device ystva. Turbo wash and turbo rinse are described in detail below with reference to FIG. fourteen.

A turbo wash is used to carry out a penetrating rinse in which the laundry is rinsed by rotating the drum 134 at high speed so as to rotate the laundry until it adheres to the drum 134, turning water not mixed with detergent, into the spiral stream and then spraying inside the drum 134 through the spiral nozzle 50 and 60 in the selected washing mode. Penetration rinsing is described in detail below with reference to FIG. fourteen.

Turbo-washing cannot be carried out in all washing modes. Therefore, turbo-washing cannot be set in some washing modes. Turbo-wash can be set in the base in a specific washing mode, or can be canceled in the base in another wash mode.

The turbo-wash icon in the form of a vortex is displayed on the 185 turbo-wash button. The turbo-wash icon is displayed after the name of the washing mode in which the turbo-wash can be selected in the mode display unit 181. That is, in the washing mode, which has a turbo-washing icon displayed after it in the mode display unit 181, the turbo-washing cannot be set.

The presence of the turbo wash setting and the presence of the basic turbo wash setting are shown in the following table 1.

Table 1 Unable to set turbo wash
HAND WASH / WOOL mode,
DELICATE mode Possible to set turbo wash Basic turbo wash setting COTTON / NORMAL mode, NANDBACK mode Basic turbo wash cancellation TOWEL mode, VOLUME / LARGE mode, BRIGHT WHITES mode, SANITARY mode, ALLERGIENE mode, TANK CLEANING mode, ENHANCED mode, QUICK WASH mode

With reference to table 1, turbo-washing is not possible in the HAND WASH / WOOL mode or the DETAILS mode. Therefore, in the case where the HAND WASH / WOOL mode or the DETAILS mode is selected in the mode selection unit 182, the turbo wash is not set, even though the user presses the turbo wash button 185.

Turbo wash can be set in the COTTON / NORMAL mode or NON-CURRENT mode, and it is mainly set. Therefore, in the case when the COTTON / NORMAL mode or the MUFFER mode is selected in the mode selection unit 182, the turbo wash is set basically. If the user presses the turbo wash button 185, the turbo wash is canceled.

Turbo wash can be set in TOWEL mode, VOLUME / LARGE mode, BRIGHT WHITES mode, SANITARY mode, ALLERGIENE mode, TANK CLEANING mode, AMPLIFIED mode or QUICK WASH mode and are canceled basically. Therefore, in the case when the TOWEL mode, the VOLUME / LARGE mode, the BRIGHT WHITES mode, the SANITARY mode, the ALLERGIENE mode, the TANK CLEANING mode, the AMPLIFIED mode or the QUICK WASH mode are selected in the mode selection block 182, the turbo wash is canceled basically. If the user presses the turbo-wash button 185, a turbo-wash is set.

In the LOAD mode, the presence of the ability to set the turbo wash and the presence of the basic turbo wash setting are determined in accordance with the mode downloaded from the network or from the peripheral device.

In FIG. 13 is a block diagram of a washing machine according to an embodiment of the present invention.

The water level sensor 145 senses the water level for the water contained in the tank 132. The water level sensor 145 is a pressure sensor for sensing air pressure in a water level sensing tube (not shown) connected to the tank 132. The water level sensor 145 senses a water level for water contained in the tank 132, according to the perceived air pressure.

The controller 199 controls the entire operation of the washing machine according to a control command that is received by the mode selection unit 182 and / or the input / output unit 184. The controller 199 is preferably provided in the control panel 180. The controller 199 may be implemented using a microcomputer (MICOM) and other electronic components. The controller 199 determines the presence of progress of each cycle, the presence of operations such as water supply, washing, rinsing, draining, draining and drying in each cycle, time, repetition rate, etc. in accordance with the washing mode selected by the mode selection unit 182, and the presence of a predetermined turbo-wash by the turbo-washing button 185.

The controller 199 controls the water supply unit 136, the motor 141, and the pump 148 in accordance with the selected wash mode or the presence of a predetermined turbo wash.

In FIG. 14 illustrates complete cycles of a washing method according to one embodiment of the present invention. In FIG. 15 illustrates the rotational speeds of the drum in a complex cycle in the washing method shown in FIG. fourteen.

The washing method according to an embodiment of the present invention can be carried out when the user sets the turbo wash through the mode selector 182 and / or the turbo wash button 185. In one embodiment, the general COTTON / NORMAL mode may become the washing method described below.

The washing cycle 210 is a cycle in which the contaminant is removed from the laundry by wetting the laundry using water mixed with the washing detergent, and then rotating the drum 134. In the washing method according to this embodiment, the washing cycle 20 includes feeding 211 water, turbo wash 212 and drainage 213.

If the wash cycle 210 is started, the controller 199 informs the user that the wash cycle 210 should be started by displaying the wash icon on the progress display of the input / output unit 184.

When supplying 211 water, water is supplied into the tank 132 from an external water source. The water supply 211 includes sensing a laundry amount 211a, an initial water supply 211b, moistening the laundry 211c, and an additional water supply 211d.

With the perception 211a of the amount of laundry, the amount of laundry (hereinafter, referred to as the “amount of laundry”) contained in the drum 134 is perceived. The amount of laundry can be perceived using various methods. In this embodiment, the amount of laundry is perceived using a method in which the controller 199 senses a deceleration time after the motor 141 rotates the drum 134 at a predetermined speed for a predetermined time.

As the deceleration time of the drum 134 increases, the level of the laundry amount increases. According to one embodiment, the controller 199 may calculate the amount of laundry to be washed by sensing an acceleration time when the drum 134 is accelerated. The controller 199 determines the amount of water supplied to the inside of the tank 132 during the initial supply of water 211b and the additional supply of water 211d, and determines the amount of water sprayed inside the drum 134 during the penetration rinse 222 or 228. The controller 199 determines the operating time for each of the other cycles.

In the initial supply of water 211b, the water mixed with the washing detergent is supplied into the tub 132, and the water not mixed with the detergent is fed into the drum 134. When the initial supply of water 211b is not mixed with detergent, it can be supplied inside the drum 134 and the water mixed with the washing detergent can then be supplied inside the tank 132. The controller 199 opens the first valve 136a for supplying water to the water supply unit 136 so as not to mix the water with the washing detergent in the detergent drawer 114, but to supply inside the tank 132 through the corrugated tube 133 for supplying water. Then, the controller 199 opens the second water supply valve 136b to the water supply unit 136 so as to mix the water with the washing detergent in the detergent drawer 114 and then to supply the inside of the tub 132 through the corrugated water supply tube 133.

The water supply inside the tank 132 by opening the first water supply valve 136a during the initial water supply 211b can be divided into a discontinuous water supply and a continuous water supply. When the water supply is interrupted, water is supplied by periodically opening the first water supply valve 136a. With a continuous supply of water, water is supplied by continuously opening the first water supply valve 136a.

The controller 199 may determine the presence of turbo-washing progress by sensing the water pressure in the cold water source C.W based on the time it takes for the water to reach the target water level with continuous water supply. This is described in detail below with reference to FIG. 16.

According to one embodiment, upon initial supply of water 211b, the controller 199 opens a third water supply valve 136c so as to spray water not mixed with the washing detergent inside the drum 134 through the spiral nozzle 50 and 60. Then, the controller 199 opens the second valve 136b for supplying water in order to mix water with washing detergent in the drawer 114 for detergents and then feed into the tank 132 through the corrugated tube 133 for supplying water.

Upon initial supply of water 211b, the hot water valve 136e of the water supply unit 136 is opened so as to supply hot water to the inside of the tank 132.

An initial supply of water 211b is carried out until the water reaches the target water level. The target water level is determined by the controller 199 in accordance with the amount of laundry, perceived prior to the initial supply of water 211b, or the selected mode. In this embodiment, a specific value is set for the target water level at which water rises slightly in the drum 134. When the laundry is wetted 211c, the amount of water that can circulate in the drum 134 is suitable for the target water level.

In the initial supply of water 211b, the water level for the water is preferably sensed by the water level sensor 145. If water flows into the tank 132 up to the target water level, the controller 199 closes the valve of the water supply unit 136, thereby ending the initial supply 211b of water.

When wetting the laundry 211c, the controller 199 controls the drum 134 to be rotated by driving the motor 141 so as to uniformly wet the laundry in the water mixed with the washing detergent, and the washing detergent is dissolved in the water. According to one embodiment, when wetting the laundry 211c, the controller 199 drives the pump 148 and the water circulates through the circulation hoses 151 and 152 so that water can be sprayed inside the drum 134 through the nozzles 160 and 170 of the sealing device.

With an additional supply of 211d water as the target water level decreases due to the wetting of laundry for washing in water, additional water is supplied inside the drum. If the controller 199 opens the first water supply valve 131a, the second water supply valve 131b or the various valves of the water supply unit 136, with additional water supply 211d, water can be supplied to the inside of the tank 132 from an external water source.

If water flows inside the tank 132 up to the target level, the controller 199 ends the additional water supply 211d by closing the first water supply valve 131a, the second water supply valve 131b, or various valves of the water supply unit 136.

In the case where the laundry is sufficiently moistened with the initial supply of water 211b, the water level does not decrease when the laundry is wetted 211c. Therefore, an additional supply 211d of water can be skipped.

In turbo-wash 212, contaminant adhering to the laundry is removed by rotating the drum 134 containing the laundry, circulating water mixed with the washing detergent, and then spraying water inside the drum 134 through nozzles 160 and 170 of the sealing device. In turbo-wash 212, the controller 199 controls the engine 141 to rotate the drum 134 at different speeds or in different directions so that the laundry is re-lifted and then dropped. Accordingly, the contaminant adhered to the laundry is removed by application of mechanical forces to the laundry, such as bending and tensile forces, friction force and impact force. According to one embodiment, when the drum 134 is rotated at a speed of 108 rpm or more, which is the speed at which the drum 134 is rotated in a state in which the laundry is attached thereto, the distribution of the laundry described further, it is possible to carry out before turbo-wash 212.

In order to prevent the engine 141 from overheating during turbo wash 212, the controller 199 may control the driving of the engine 141 in order to pause it from an interval of several seconds to several minutes.

Turbo wash 212 is performed when the user sets the turbo wash through block 182 mode selection and / or button 185 turbo wash.

When turbo-washing 212, the controller 199 controls the pump 148 to drive so that the water mixed with the washing detergent in the tub 132 circulates through the circulation hoses 151 and 152, and then spray it inside the drum 134 through the nozzles 160 and 170 sealing devices. In the case where the amount of circulating water is too large, the formation of many bubbles may occur. Therefore, it is preferable to specify a certain amount of water at which water can circulate.

In the event that a decision is made that the pump 148 failed during turbo-washing 212, the turbo-washing is canceled and a general washing can be carried out. This is described in detail below with reference to FIG. 17.

In the case where the amount of laundry to be washed is not less than the reference amount of laundry to wash, or the selected washing mode is the ENHANCED mode for turbo-washing 212, the controller 199 activates the pump 148 when the engine 141 is stopped so that overheating can be prevented engine 141, and in order to reduce maximum energy consumption. This is described in detail below with reference to FIG. 18 and 19.

When turbo-washing 212, the controller 199 may open a third valve 131c for supplying water to the water supply unit 136 so that water flows into the fifth water supply hose 131g through the dispenser, mixes with bleach in the detergent drawer 114, and then flows into the tank 132 through the corrugated tube 133 for supplying water. The bleach is supplied until the water reaches the target water level. If the water mixed with the bleach flows inside the tank 132 up to the target water level, the controller 199 closes the third water supply valve 131c for the water supply unit 136. The water mixed with the bleach is preferably supplied as the last turbo-wash 212 immediately before the turbo-wash 212 is completed.

When draining 213, water in the tank 132 is diverted outside the tank 132. When draining 213, the controller 199 drives the pump 148 so that water in the tank 132 is diverted outside the drain hose 149. When draining 213, the drum 134 can be stopped, but it can be rotated while maintaining speed while turbo-washing 212.

In the wash cycle 210 described above, the turbo wash 212 can be carried out as a general wash in accordance with the setting of the turbo wash. In the case where the general wash is set, since the turbo wash is canceled, the turbo wash 212 is carried out as a general wash.

In general washing, the controller 199 controls the motor 141 to rotate the drum 134. However, since the pump 148 does not work, water does not circulate. Accordingly, water is not sprayed inside the drum 134 through nozzles 160 and 170 of the sealing device.

The complex cycle 220 is a cycle for removing detergent remaining in the laundry and removing water from the laundry, in which rinsing and water removal cycles are combined in a general washing method. Integrated cycle 220 includes a distribution of 221 laundry, penetrating rinse 222, easy removal of 223 water, a supply of 224 water, turbo rinse 225, drainage 226, a distribution of 227 laundry, penetrating rinse 228 and the main removal 229 of water. If complex cycle 220 begins, controller 199 preferably displays a rinse icon and / or a water removal icon on the progress display of the input / output unit 184.

In the distribution of 221 laundry, the laundry is distributed by repeating the process of maintaining a constant speed of the drum 134 and then slowing down the drum after the drum 134 is accelerated. When penetrating rinse 222 and / or simply removing 223 water, such a phenomenon arises that the laundry is shifted to one side due to tangling of the laundry. Consequently, a displacement relative to the center can be caused at which one side of the drum 134 increases the mass relative to the center of the drum 134. Since the displacement of the laundry with respect to the center causes noise and vibration to be generated by the high speed rotation of the drum 134, the laundry is evenly distributed before the penetrating rinse 222 and / or simply removing 223 water. The distribution of laundry 221 is carried out by repeating the process of maintaining a constant speed of the drum 134 and then slowing down the drum after the drum 134 is accelerated.

According to one embodiment, when the laundry is distributed 221, water can be sprayed in the direction of the laundry through the nozzles 160 and 170 of the sealing device or the spiral nozzle 50 and 60.

With penetrating rinse 222, when the laundry is rotated by rotating the drum 134 while it is attached to the drum 134, the remaining detergent and contaminant are removed by spraying water not mixed with the detergent inside the drum 134 through the spiral nozzle 50 and 60 so that the water passes through the laundry.

With the penetration rinse 222, the controller 199 controls the motor 141 to rotate the drum 134 so that the laundry adheres to the drum 134, and opens the third water supply valve 131c so as to spray water inside the drum 134 through the spiral nozzle 50 and 60. In this case, the controller 199 preferably drives the pump 148 so that the water in the tank 132 is led out through the drain hose 149.

The penetrating rinse 222 is carried out when the user sets the turbo wash through the mode selector 82 and / or the turbo wash button 185.

With the penetrating rinse 222, the drum 134 is rotated at a speed of 1G, i.e. 108 rpm or more, at which the laundry is rotated while it is attached to the drum 134. With the penetrating rinse 222, the laundry is preferably not separated from the drum 134, while it is attached to the drum 134. This case, when the laundry is not separated from the drum 134, means that part of the laundry is temporarily separated in an exceptional situation, and means that the majority of the laundry is stuck to the drum 134 for the greatest hours Asti time.

When penetrating the rinse 222 at the drum 134 preferably maintain a constant speed. In one embodiment, the drum 134 may be accelerated. In this embodiment, when penetrating the rinse 222, the drum 134 is accelerated from 400 to 600 rpm./min and then save 600 rpm.

With the simple removal of 223 water, the drum 134 is rotated at high speed so as to separate the water from the laundry. The controller 199 closes the third water supply valve 131c after the penetrating rinse 222 so as to stop the spraying of water, and sequentially rotates or stops the drum 134 at a certain speed or more, where the laundry is rotated while it is attached to the drum 134, without slowing down or stopping the drum 134.

Hereinafter, the term “sequentially” means that the drum 134 is rotated non-stop between stages, and includes a value such that the speed of the drum 134 is changed by acceleration or deceleration.

By simply removing 223 water from the laundry, the water is optionally removed to the extent that the laundry is dry, and therefore, the drum 134 is preferably rotated at a speed of about 700 rpm. Preferably, by simply removing the water 223, the controller 199 periodically drives the pump 148 so as to drain the water in the tank 132 outward through the drain hose 149.

The simple removal of water 223 is carried out by accelerating the drum 134 with stopping or slowing down the drum 134 when penetrating rinse 222 so that the distribution of the laundry does not separate between the penetrating rinse 222 and the simple removal of 223 water. That is, the penetrating rinse 222 and the simple removal of water 223 are successively carried out without distributing the laundry so that the total time can be reduced and in order to minimize damage to the laundry.

According to one embodiment, the drum 134 preferably maintains a certain speed or greater where the laundry is rotated while it is attached to the drum 134 so that the distribution of the laundry is not necessary, even though the drum 134 is slowed between the penetrating rinse 222 and the simple removal of 223 water. That is, the drum 134 is preferably rotated at a speed of 1G, i.e. 108 rpm or more, where the laundry is rotated while it is attached to the drum 134, from the penetrating rinse 222 to a simple removal of water 223, so that Laundry for washing does not separate from the drum 134, while it is attached to the drum 134.

The penetrating rinse 222 described above is a process essentially carried out by simply removing 223 water. With the penetrating rinse 222, when a simple removal of water 223 is carried out after the distribution of the laundry 221, the controller 199 opens the third water supply valve 131c so that the penetrating rinse 222 is carried out while the water is sprayed inside the drum 134 through the spiral nozzle 50 and 60. Thus, in the case where a turbo wash is specified, the penetrating rinse 222 can be carried out at any time when the drum 134 is accelerated or maintained at a speed during simple removal of water. Alternatively, the penetrating rinse 222 may be divided into a plurality of substages to be carried out. That is, the penetrating rinse 222 can be carried out at any time, not only before the simple removal of 223 water after the distribution 221 of laundry, but also in the middle of a simple removal 223 of water.

However, the penetrating rinse 222 is preferably not performed at the end of a simple removal of water 223, and a simple removal of water 223 is necessarily resumed after the penetrating rinse 222.

In the case where the turbo wash is not set, water is not sprayed inside the drum 134 through the spiral nozzle 50 and 60 during the simple removal of 223 water, and therefore, the penetrating rinse 222 is not carried out.

Similar to the supply 211 of water in the wash cycle 210 described above, water is supplied to the inside of the tub 132 from an external water source while supplying 224 water. The water supply 224 may include an initial water supply, wetting the laundry and an additional water supply.

When supplying 224 water, the controller 199 opens the first and second water supply valves 136a and 136b so as to mix the water with the rinse detergent in the detergent drawer 114 and then feed the tub 132 through the corrugated water supply tube 133. The rinse detergent is generally a fabric softener, but may contain various functional detergents, such as a detergent to create a pleasant odor.

According to one embodiment, when supplying 224 water, controller 199 may open a third water supply valve 136c so that water not mixed with washing detergent is sprayed inside drum 134 through a spiral nozzle 50 and 60.

When water 224 is supplied, drum 134 is preferably stopped. However, water 224 can be supplied after the drum 134 is slowed to a speed of 1G, i.e. 108 rpm or more, where the laundry is rotated while it is attached to the drum 134.

In turbo rinse 225, the remaining detergent and laundry contaminant are removed by rotating the drum 134 containing the laundry, circulating water mixed with the rinse detergent, and then spraying the water inside the drum 134 through nozzles 160 and 170 of the sealing device. In turbo rinse 225, controller 199 controls motor 141 to rotate drum 134 at different speeds or in different directions so that laundry can be re-lifted and then dropped. In this way, the remaining detergent and the laundry contaminant are removed by applying mechanical forces to the laundry, such as bending and tensile forces, friction force and impact force. According to one embodiment, when the drum 134 is rotated at a speed of 108 rpm or more, which is the speed at which the drum 134 is rotated in a state in which the laundry is attached thereto, the distribution of the laundry described further, it is possible to carry out before turbo rinse 225.

In order to prevent overheating of the engine 141 during turbo rinse 225, the controller 199 may control the driving of the engine 141 in order to suspend it at intervals of several seconds to several minutes.

Turbo rinse 225 is carried out when the user sets the turbo wash through the mode selector 182 and / or the turbo wash button 185. In the case where the turbo wash is canceled in order to set the total wash, turbo rinse 225 is carried out as a general rinse. With a general rinse, the controller 199 controls the motor 141 in order to rotate the drum. However, since pump 148 is not driven, water does not circulate. Accordingly, water is not sprayed inside the drum 134 through nozzles 160 and 170 of the sealing device.

During turbo rinse 225, controller 199 drives pump 148 so that water mixed with rinse detergent in tank 132 circulates through circulation hoses 151 and 152, and then spray it inside drum 134 through nozzles 160 and 170 of the sealing device . In the case where the amount of circulating water is too large, the formation of many bubbles may occur. Therefore, the amount of water is preferably set to a certain extent to which water can circulate.

In the event that a decision is made that the pump 148 failed during the turbo rinse 225, the turbo wash is canceled and a general wash can be performed. This is described in detail below with reference to FIG. 17.

In the case where the amount of laundry to be washed is not less than the reference amount of laundry to be washed or the selected washing mode is the ENHANCED mode for turbo rinsing 225, the controller 199 drives the pump 148 when the engine 141 is stopped to prevent overheating of the engine 141 and to reduce maximum energy consumption. This will now be described in detail with reference to FIG. 18 and 19.

Like the drainage 213 of the wash cycle 210 described above, water in the tub 132 is diverted to the outside during drainage 226.

In one embodiment, water supply 224, turbo rinse 225, and drainage 226 may be in another form or may be skipped. Water supply 224, turbo rinse 225 and drainage 226 can be carried out in a state in which the drum 134 is not stopped by deceleration after simply removing 223 water. In this case, the distribution of 227 laundry can be skipped.

Like the laundry distribution 221 described above, the laundry is distributed by repeating the process of maintaining a constant speed of the drum 134 and then slowing down the drum after the drum 134 is accelerated by distributing the laundry 227. With the distribution of the laundry 227, the laundry is evenly distributed before the penetrating rinse 228 and / or the main removal of water 228. As shown in FIG. 15, the distribution of the laundry 227 is carried out by repeating the process of maintaining a constant speed of the drum 134 and then slowing down the drum after the drum 134 is accelerated.

As described above, in the distribution of 227 laundry, water can be sprayed in the direction of the laundry through the nozzles 160 and 170 of the sealing device or the spiral nozzle 50 and 60.

Like the penetrating rinse 222 described above, with the penetrating rinse 228, when the laundry is rotated by rotating the drum 134 while it is attached to the drum 134, the remaining detergent and contaminant are removed by spraying water not mixed with the detergent inside drum 134 through a spiral nozzle 50 and 60 so that water passes through the laundry.

With the penetration rinse 228, the controller 199 controls the motor 141 to rotate the drum 134 so that the laundry adheres to the drum 134 and opens a third water supply valve 131c so as to spray water inside the drum 134 through the spiral nozzle 50 and 60. In this case, the controller 199 preferably drives the pump 148 so that the water in the tank 132 is led out through the drain hose 149.

The penetrating rinse 228 is carried out when the user sets the turbo wash through the block 182 mode selection and / or button 185 turbo wash.

With the penetrating rinse 228, the drum 134 is rotated at a speed of 1G, i.e. 108 rpm or more, at which the laundry is rotated while it is attached to the drum 134. With the penetrating rinse 228, the laundry is preferably not separated from the drum 134, while it is attached to the drum 134.

When penetrating the rinse 228, the drum 134 preferably maintains a constant speed. In one embodiment, the drum 134 may be accelerated. In this embodiment, with a penetrating rinse 227, 1000 rpm are stored at the drum 134 and then accelerated to 1060 rpm. After that, the drum 134 save 1060 rpm./min

Like the simple removal of water 223 described above, with the main removal of water 229, the drum 134 is rotated at high speed in order to separate the water from the laundry. The controller 199 closes the third water supply valve 131c after the penetrating rinse 228 so as to stop the spraying of water, and sequentially rotates or accelerates the drum 134 at a certain speed or more, where the laundry is rotated while it is attached to the drum 134, without slowing down or stopping the drum 134.

With the main removal of 229 water, the drum 134 is preferably rotated up to a maximum speed of 1000 rpm or more so as to dry the laundry to the maximum extent. In this embodiment, the drum 134 is rotated up to 1300 rpm. Preferably, with the main removal of water 229, the controller periodically activates the pump 148 so that the water in the tank 132 is diverted out through the drain hose 149.

The main removal of water 229 is carried out by accelerating the drum 134 without stopping or slowing down the drum 134 when penetrating the rinse 228 so that the distribution of the laundry does not occur between the penetrating rinse 228 and the main removal 229 of water. The penetrating rinse 228 and the main removal 229 of water are sequentially carried out without distributing the laundry so as to possibly reduce the total time and to minimize damage to the laundry.

In one embodiment, the drum 134 preferably maintains a certain speed or greater where the laundry is rotated while attached to the drum 134 so that the distribution of the laundry is not necessary, even though the drum 134 is slowed between penetrating rinse 228 and the main removal of 229 water. That is, the drum 134 is preferably rotated at a speed of 1G, that is, 108 rpm or more, where the laundry is rotated while it is attached to the drum 134, from the penetrating rinse 228 to the main water removal 229 so that the laundry for washing, do not separate from the drum 134, while it is attached to the drum 134.

The penetrating rinse 228 described above is a process essentially carried out with the main removal of 229 water. With the penetrating rinse 228, when the main removal of water 229 is carried out after the distribution of the laundry 227, the controller 199 opens the third water supply valve 131c so that the penetrating rinse 228 is carried out while the water is sprayed inside the drum 134 through the spiral nozzle 50 and 60. Thus, in the case where a turbo wash is specified, the penetrating rinse 228 can be carried out at any time when the drum 134 is accelerated or maintained at a speed during simple removal of water. Alternatively, the penetrating rinse 222 may be divided into a plurality of substages to be carried out. That is, the penetrating rinse 228 can be carried out at any time, not only before the main removal of water 229 after the distribution 227 of laundry, but also in the middle of the main removal 229 of water.

However, the penetrating rinse 228 is preferably not performed at the end of the main water removal 229, and the main water removal 229 is necessarily resumed after the penetrating rinse 228.

In the case where the turbo wash is not set, water is not sprayed inside the drum 134 through the spiral nozzle 50 and 60 during the main removal of water 229, and therefore, the penetrating rinse 228 is not carried out.

A drying process in which laundry is dried by supplying a stream of hot air inside the drum 134 can be carried out after the main removal of 229 water.

Each stage of the complex cycle 220 can be modified or skipped.

In FIG. 16 is a flowchart illustrating a method for measuring water pressure in a washing method according to an embodiment of the present invention.

The user sets the turbo wash through the mode selector 182 and / or the turbo wash button 185 (S310). A turbo wash is used to carry out a turbo wash in which laundry is washed by rotating the drum 134, circulating water mixed with the washing detergent, and then spraying water inside the drum 134 through nozzles 160 and 170 of the sealing device in the selected mode washing, and / or turbo rinsing, wherein the laundry is rinsed by rotating the drum 134, circulating water mixed with the rinse detergent, and then spraying the water inside the drum 134 through nozzles 160 and 170 of the sealant device.

The turbo wash is used to carry out a penetrating rinse in which the laundry is rinsed by spraying water not mixed with detergent inside the drum 134 through the spiral nozzle 50 and 60 when the laundry is rotated while it is attached. to the drum by rotating the drum 134 in the selected washing mode.

If the washing is started after the turbo-washing is set, the washing cycle 210 is started so that the controller 199 delivers water 211. If water supply 211 is started, the laundry amount is perceived 211a, and then the initial water supply 211b is carried out.

If the controller 199 periodically opens the first water supply valve 136a during the initial supply of water 211b, an intermittent water supply is provided at which water is supplied to the inside of the tank 132 through the corrugated water supply pipe 133 (S320). In this embodiment, the interrupted water supply is carried out six times at intervals of 0.3 seconds.

After the interrupted water supply, the controller 199 integrates the time by activating the timer and opens the first water supply valve 136a so as to start a continuous water supply, in which water is supplied into the tank 132 through the corrugated water supply pipe 133 (S330).

The timer is a time integrator included in the controller 199, and the timer starts to work together with the start of continuous water supply. If a continuous water supply is started, water is supplied to the tank 132.

The controller 199 decides whether the water level for the water contained in the tank 132, sensed by the water level sensor, reaches the target water level (S340). In the case where the water level for water does not reach the target water level, the controller 199 continuously delivers a continuous supply of water so that the timer continuously integrates the time.

In the case where the water level for water reaches the target water level, the controller 199 ends the continuous supply of water and stops the timer (S350). In the case where the water level for water reaches the target water level, the controller 199 closes the first valve 136a for water supply, and calculates the integrated time by stopping the timer.

The controller 199 decides whether the timer-integrated continuous water supply time is longer than the target time (S360). The controller 199 compares with the target time the time of continuous water supply, which is the time elapsed until the water level for water in the tank 132 reaches the target water level by means of a continuous water supply.

In the case where the continuous water supply time is not more than the target time, the controller 199 decides that the water pressure of the cold water source C.W is normal and performs a turbo wash (S390). In the case where the continuous water supply time is not longer than the target time, the controller 199 performs a turbo wash 212 in the washing cycle 210 and carries out a penetrating rinse 222 and 228 and a turbo rinse 225 in the complex cycle 220.

In the case where the continuous water supply time is longer than the target time, the controller 199 decides that the water pressure of the cold water source C.W is low and displays the cancellation of the turbo wash outside (S370). In the case where the continuous water supply time is longer than the target time, the controller 199 cancels the turbo wash and displays the cancellation of the turbo wash in the input / output unit 184 or flashes the light of the turbo wash button 185 several times and then turns off the light of the turbo 185 button washing.

After the turbo wash is canceled, the controller 199 performs a general wash (S380). The controller 199 performs a common wash in the wash cycle 210. The controller 199 does not carry out a penetrating rinse 222 and 228 and performs a general rinse.

In FIG. 17 is a flowchart illustrating a method for determining a pump failure in a washing method according to one embodiment of the present invention.

The user sets the turbo wash through the mode selector 182 and / or the turbo wash button 185 (S410). A turbo wash is used to carry out a turbo wash in which laundry is washed by rotating the drum 134, circulating water mixed with the washing detergent, and then spraying water inside the drum 134 through nozzles 160 and 170 of the sealing device in the selected mode a wash and / or turbo rinse in which the laundry is rinsed by rotating the drum 134, circulating water mixed with the rinse detergent, and then spraying water inside the drum 134 through nozzles 160 and 170 of the seal device.

The turbo wash is used to carry out a penetrating rinse in which the laundry is rinsed by spraying water not mixed with detergent inside the drum 134 through the spiral nozzle 50 and 60 when the laundry is rotated while it is attached. to the drum by rotating the drum 134 in the selected washing mode.

If the washing is started after the turbo-washing is set, the washing cycle 210 is started so that the controller 199 supplies water 211 (S420). When supplying 211 water, water is supplied into the tank 132 from an external water source. When supplying water 211, the controller 199 opens various valves of the water supply unit 136, including the first or second water supply valve 131a or 131b, etc., so as to supply water supplied from an external water source to the tank 132 through a corrugated tube 133 for water supply.

If the supply of water 211 is completed, turbo-washing 212 is performed. Then, the controller 199 drives the pump 148 to circulate the water (S430). If the pump 148 is driven, the water mixed with the washing detergent in the tub 132 is circulated through the circulation hoses 151 and 152, and then it is sprayed inside the drum 134 through the nozzles 160 and 170 of the sealing device.

When the pump 148 is driven, the controller 199 decides whether the water level for the water contained in the tank 132, which is sensed by the water level sensor 145, is lower than the predetermined water level (S440). If the pump 148 is driven in order to circulate water, a certain amount of water is stored in the circulation hoses 151 and 152, and therefore, a decrease in the water level for the water stored in the tank 132. Thus, the controller 199 decides whether whether the pump 148 failed by comparing with the set water level the water level for the water contained in the tank 132 sensed by the water level sensor 145 when the pump 148 is operating.

If the perceived water level is lower than the set water level, the controller 199 decides that the pump 148 is operating normally and performs a turbo wash (S450). If the perceived water level is lower than the set water level, the controller 199 performs a turbo wash 212. The controller 199 performs a penetrating rinse 222 and 228 and a turbo rinse 225 in a complex cycle 220.

If the perceived water level is not lower than the set water level, the controller 199 decides that the pump 148 has failed. Then, the controller 199 stops the operation of the pump 148 and displays the cancellation of the turbo wash. If the perceived water level is lower than the set water level, the controller 199 stops the pump 148. The controller 199 cancels the turbo wash and displays the cancellation of the turbo wash in the input / output unit 184 or flashes the light of the turbo wash button 185 several times and then turns off the light buttons 185 turbo wash.

The controller 199 provides an additional water supply (S480). Since water is additionally required for general washing rather than turbo-washing, the controller 199 opens various valves of the water supply unit 136, including the first or second water supply valve 131a or 131b, etc., so as to supply the water supplied from an external water source, into the tank 132 through a corrugated tube 133 for supplying water.

If completing the additional water supply, the controller 199 performs a common wash (S490). The controller 199 performs a general wash. The controller 199 does not penetrate the rinse 222 and 228 in the complex cycle 220 and performs a general rinse.

The above described washing method is described for the main supply 211 of water and turbo-wash 212 in the wash cycle 210, but it can be applied to the supply of 224 water and turbo rinse 225 in the complex cycle 220.

In FIG. 18 is a flowchart illustrating a method of driving a pump in a washing method according to an embodiment of the present invention.

The user sets the turbo wash through the mode selector 182 and / or the turbo wash button 185 (S510). A turbo wash is used to carry out a turbo wash in which laundry is washed by rotating the drum 134, circulating water mixed with the washing detergent, and then spraying water inside the drum 134 through nozzles 160 and 170 of the sealing device in the selected mode washing, and / or turbo rinsing, wherein the laundry is rinsed by rotating the drum 134, circulating water mixed with the rinse detergent, and then spraying water inside the drum 134 through nozzles 160 and 170 to seal device.

The turbo wash is used to carry out a penetrating rinse in which the laundry is rinsed by spraying water not mixed with detergent inside the drum 134 through the spiral nozzle 50 and 60 when the laundry is rotated while it is attached. to the drum by rotating the drum 134 in the selected washing mode.

If the washing is started after the turbo-washing is set, the washing cycle 210 is started so that the controller 199 delivers water 211 (S520). When the laundry amount amount 211a is perceived, the laundry amount, which is the amount of laundry placed in the drum 134, is sensed. The controller 199 controls the motor 141 to rotate the drum 134 at a predetermined speed for a predetermined time and then brake drum 134. Thus, the amount of laundry to perceive by measuring the time delay.

The controller 199 decides whether the perceived amount of the laundry is larger than the reference amount of the laundry (S530). The controller 199 senses the laundry amount 211a, and then compares the perceived amount of the laundry with the reference amount of the laundry.

In the case where the perceived amount of the laundry is not greater than the reference amount of the laundry, the controller 199 drives the pump 148 when the engine 141 is driven by turbo-washing 212 or turbo-rinsing 225 to circulate water (S540 ) With a turbo wash 212 or turbo rinse 225, the controller 199 drives the pump 148 when the drum 134 is rotated while the engine 141 is running so as to circulate water in the tank 132 through the circulation hoses 151 and 152 and then spray it inside the drum 134 through nozzles 160 and 170 of the sealing device.

In the case where the perceived amount of the laundry is larger than the reference amount of the laundry, the controller 199 drives the pump 148 when the engine 141 is stopped so as to circulate water (S550). In the case where the perceived amount of the laundry is larger than the reference amount of the laundry, overheating of the engine 141 may occur, and therefore, an increase in energy consumption also occurs. Thus, when turbo-washing 212 or turbo-rinsing 225, the controller 199 stops the engine 141 and drives the pump 148 so that when the drum 134 is slowed down or stopped, the water in the tank 132 will be circulated through the circulation hoses 151 and 152 and then spray it inside the drum 134 through the nozzles 160 and 170 of the sealing device. In this case, although there is a slight decrease in the washing or rinsing efficiency, it is possible to prevent overheating and reduce the maximum energy consumption.

In FIG. 19 is a flowchart that illustrates a method of washing in the STRONG mode in a washing method according to one embodiment of the present invention.

If the user sets the ENHANCED mode by the mode selection unit 182, the ENHANCED mode is set (S610). ENHANCED mode can be selected when the amount of laundry is large or the laundry is dirty.

If you set the mode to STRONG, the turbo-wash is basically canceled, as described above.

The turbo wash is canceled and the general wash set (S620). In the case when the user starts the wash while maintaining the general wash, which is the basic setting of the STRONG mode, the turbo wash is canceled and the general wash is set.

In the case where the turbo wash is canceled and the general wash is set in the STRONG mode, the controller 199 drives the pump 148 when the engine 141 is stopped when washing or rinsing so as to circulate water (S630).

In general washing, the general washing instead of the turbo-washing 212 is carried out in a different washing mode and the general rinsing is performed instead of the turbo-rinsing 225. However, in the STRONG mode, the turbo-washing 212 and / or the turbo-rinsing 225 are performed. In this case, the penetrating rinse 222 and 228 do not carry out.

Since the STAFFED mode requires high washing and rinsing efficiency, the turbo-wash 212 and / or the turbo-rinse 225 are preferably carried out even when the user sets the general wash. However, in order to prevent overheating and reduce maximum energy consumption, when turbo-washing 212 or turbo-rinsing 225, the controller 199 stops the engine 141 and drives the pump 148 so that when the drum 134 is slowed down or stopped, the water circulates in the tank 132 through the circulation hoses 151 and 152 and then spray it inside the drum 134 through the nozzles 160 and 170 of the sealing device.

Although the preferred embodiment and other embodiments of the process for producing high purity alumina in accordance with the present invention are explained in detail with reference to the accompanying drawings, however, embodiments of the present invention are not limited thereto, and it is obvious that various modifications and others embodiments are possible within the scope of the invention. Accordingly, essentially the scope of the invention is determined only by the attached claims and their equivalents.
