The heater 670 may be a heater or a heater.

In detail, a detergent container 15 is provided at the upper end of the cabinet 10, and wash water flows into the detergent container 15 through the washing water supply pipe 14. Further, the garment receiving portions 20 and 30 may be supported through a plurality of support portions 21. The support portion 21 may be composed of a damper.

The cabinet 10 includes a front panel 11 forming a front surface of the clothes processing apparatus. The front panel 11 is provided with a loading port 13 for loading laundry into the clothes receiving portion or for taking laundry out of the clothes receiving portion, .

The loading port 13 is opened and closed by a door 40 rotatably coupled to the cabinet 10. [

The front panel 11 may be provided with a control panel 17, which is a user interface. The control panel 17 is a means for allowing a user to exchange information with a control unit (not shown) of the garment processing apparatus 1. [

The clothes receptacle provided in the cabinet 10 may include a tub 20 in which wash water is stored, and a drum 30 in which laundry is rotatably installed in the tub.

The tub 20 is provided in a cylindrical shape and is fixed to the inside of the cabinet 10 by the tub supporting portion 21. The tub opening portion 210 communicating with the inlet 13 is provided on the front surface 220 of the tub.

A gasket 50 is provided between the tub opening 210 and the inlet port 13. The gasket 50 not only prevents the vibration generated in the tub 20 from being transmitted to the cabinet 10, It is preferable to use an elastic material such as rubber to prevent the washing water stored in the washing water from leaking.

The drum 30 is rotatably supported inside the tub 20 by a driving unit provided on the rear surface of the tub 20. The drum 30 has a drum opening 310 communicating with the tub opening 210, And a through-hole 31 provided so as to pass through the through-hole 31.

The present invention may further include an air circulating duct (60) for circulating the air inside the clothes receiving portion. The air circulation duct (60) is provided to circulate air in the interior of the garment accommodating portion and exhausts some of the air to the exhaust duct (61), so that the circulation type clothes processing apparatus and the exhaust type garment processing apparatus Processing apparatus can be provided.

Hereinafter, for the sake of convenience of explanation, it is assumed that the clothes processing apparatus including the air circulation duct 60 is assumed.

The air circulation duct 60 may be provided on the upper circumferential surface 230 of the tub 10 for guiding the air inside the tub 20 to the outside of the tub 20 and then guiding the air to the tub 20.

The tub 20 may include a first communication portion 610 and a second communication portion 630 for coupling with the air circulation duct 60.

2, the first communication portion 610 is a channel for guiding the air inside the tub 20 to the air circulation duct 60, and the second communication portion 630 is a channel for guiding the air inside the air circulation duct 60 To the tub (20).

The second communication portion 630 may be provided in the gasket 50. That is, the second communication portion 630 is provided with a hole penetrating the gasket 50, and the air outlet of the air circulating duct 60 can be coupled to the hole formed in the gasket 50.

The second communicating part 630 may be provided on the circumferential surface 230 of the tub as in the first communicating part 610. When the second communicating part 630 is provided in the gasket 50, Can be supplied to the central portion of the drum 30 through the drum opening 310, which is advantageous for increasing the heat exchange efficiency between the laundry and the air.

The heating unit provided to supply the heated air to the tub 20 may include a fan 640 and a heater 670 provided in the air circulation duct 60. The fan 640 not only allows the air inside the tub 20 to flow into the air circulation duct 60 through the first communication portion 610 but also returns the air introduced into the air circulation duct 60 back to the tub 20 . The heater 670 is means for heating the air introduced from the tub 20 through the second communication portion 630 by the operation of the fan 640.

In this case, it is preferable that the first communication portion 610 and the second communication portion 630 are disposed in a diagonal direction with respect to the cross section of the tub parallel to the ground on which the cabinet 10 is supported, May include a portion extending along the longitudinal direction of the air circulation duct (60). The length of the flow path formed by the air circulation duct 60 is made long to secure a sufficient time for the air moving along the air circulation duct 60 to be heated.

A part of the air supplied to the tub 20 through the air circulation duct 60 is discharged to the outside of the tub 20 through the exhaust duct 61 and is discharged into the air circulation duct 60 by the fan 640 A part of the incoming air is supplied from the outside through the intake duct (62) as well as the tub (20).

It is preferable that the intake duct 62 is provided on the flow path through which air in the tub 20 flows into the fan 640. This means that the air circulation inside the tub 20 and the air outside the tub 20 can be circulated by the air circulation by only the fan 640 provided in the air circulation passage 60 without providing the separate air introduction means in the intake duct 62 To the duct (60).

2 shows an example in which the air in the outside of the tub 20 is introduced into the air circulation duct 60 through the first communication part 610 by the intake duct 62. In this case, since the negative pressure is formed in the first communication part 610 when the fan 640 rotates, the air inside the tub 20 and the air outside the tub 20 flow into the air circulation duct 60 Will be.

In the meantime, the intake duct 62 provided in the present invention does not require a separate control means (valve or the like) for controlling the opening and closing of the intake duct 62. That is, the intake duct 62 provided in the present invention may be provided so as to be always kept open.

1 and 2, the exhaust duct 61 communicates the inside of the tub 20 and the outside of the cabinet 10 to guide the air introduced into the exhaust duct 61 to the outside of the cabinet 10 The tub 20 may be connected to a drain passage 90 provided to discharge washing water.

Since the air discharged through the exhaust duct 61 is highly humid air, if the exhaust duct 61 is provided so as to communicate directly with the outside of the cabinet 10, the air discharged from the exhaust duct 61 is condensed on the indoor wall Because it can cause problems.

Since the drainage passage 90 for discharging the washing water in the tub 20 to the outside of the cabinet 10 is provided in the garment treating apparatus 1 of the present invention, if the exhausting duct 61 is connected to the drainage passage 90 One problem can be solved.

In this case, the connection point between the exhaust duct 61 and the drain passage 90 is preferably provided with a passage switching portion 16 for controlling the opening and closing of the exhaust duct and the drain passage 90. The air discharged through the exhaust duct 61 is prevented from flowing into the tub 20 and the water discharged through the drainage duct 90 is prevented from being reintroduced into the tub 20. [

It is preferable that the passage switching portion 16 provided at the connection point between the exhaust duct 61 and the drainage passage 90 is provided at a position higher than the maximum water level set on the tub 20. [

When the passage switching unit 16 is provided at a position higher than the maximum water level set on the tub 20 as in the present invention, the exhaust duct 61 plays a role of preventing a siphon phenomenon, (Second drainage flow path) between the portion 16 and the pump 93 so that the malodor can be prevented from flowing into the tub 20.

Since the air introduced into the exhaust duct 61 can be discharged to the outside of the tub through the flow path switching unit 17, the rotation speed control of the fan 640 for removing the water trap is unnecessary.

Also, the above-described structure can prevent the wash water from being discharged to the outside of the tub 2 through the drainage flow passage 6 even if the washing water is supplied to the highest level set in the tub 2. [

1 and 2 show a clothes processing apparatus 1 in which a circulation type and a discharge type structure are mixed, but the present invention is not limited thereto, and only a circulation type structure or only a discharge type structure can be applied.

FIGS. 3-6 illustrate embodiments of the present invention including a rib structure 70 that affects the flow of air exiting through the first communication portion 610. FIG. In addition, in order to clearly show the structure of the rib 70, some configurations of the clothes processing apparatus 1 are omitted or briefly shown.

3 shows a gasket rib 710. The gasket rib 710 is provided in the gasket 50 and is provided around the first communication portion 610 in which the gasket 50 and the air circulation passage 60 communicate. Specifically, a gasket rib 710 is provided between the first communication portion 610 and the tub opening 210.

3, a part of the air flowing in the direction of the tub opening 210 through the first communicating part 610 flows into the drum 30 through the drum opening part 310, assuming that there is no gasket rib 710 , And a part of the air flows into the space between the tub 20 and the drum 30. [

The air introduced into the space between the tub 20 and the drum 30 is discharged to the air circulation passage 60 through the second communication portion 630 without heat exchange (drying) with the laundry in the drum 30 do. That is, since the air not actually used for drying is heated by the heater 670, energy efficiency is very low.

However, the gasket ribs 710 may serve to prevent air from leaking into the space between the tub 20 and the drum 30.

3, the gasket rib 710 is provided between the first communication portion 610 and the tub opening 210 and is provided at the periphery of the upper end of the gasket 50 where the first communication portion 610 is located. That is, the air introduced through the first communication portion 610 is primarily clogged by the gasket ribs 710 and diffuses after passing a predetermined distance further in the direction of the door 40 (in the direction of the paper surface).

Since a space between the tub 20 and the drum 30 corresponds to a shape in which the gasket ribs 710 intercept the air, more air can be introduced into the drum opening 310.

Specifically, the gasket ribs 710 extend from the gasket 50 toward the center of the gasket 50 or toward the center of the tub opening 210. Or may extend in a direction parallel to the plane including the tub opening 210. [

At this time, it is preferable that the gasket ribs 710 extend to a level not contacting the drum 30. That is, it is preferable that the gasket rib 710 should not contact the drum opening 310, specifically, be shorter than the shortest distance between the gasket 50 and the drum 30.

The drum 30 can not rotate smoothly when contact with the tub 20 and the gasket 50 occurs when the drum 30 rotates. Therefore, the length of the gasket rib 710 needs to be adjusted to such an extent that it does not come into contact with the drum 30 as described above.

Also, a plurality of gasket ribs 710 may be provided along the inner circumferential surface of the gasket 50. Since the gap formed between the tub opening 210 and the drum opening 310 forms a circular ring, a plurality of gasket ribs 710 may be provided in the gasket 50 along the clearance.

Further, the gasket ribs 710 may be provided in the form of a disk including an opening along the inner circumferential surface of the gasket 50 to prevent air from escaping through the circular annular gap more precisely. That is, a plurality of gaskets 50 among the above-mentioned embodiments correspond to a continuously connected type.

4 corresponds to a view having the tub rib 720. FIG. The tub rib 720 is provided on the inner circumferential surface of the tub 20. In an embodiment of the present invention, the inner circumferential surface of the tub 20 is provided on the inner circumferential surface of the tubular surface 220. On the other hand, the inner circumferential surface of the tubular circumferential surface 230 and the inner circumferential surface of the tub opening 210 may be provided. It is preferable that it is provided on the inner circumferential surface of the tubular electric field 220 because it is ineffective because it corresponds to a position similar to the gasket rib 710.

The tub rib 720 also functions to prevent the inflow of air into the space between the tub 20 and the drum 30 through the first communicating part 610 and the tub opening 210 in this order. That is, it plays the role of increasing the resistance of the air passage between the tub 20 and the drum 30.

The tub rib 720 extends toward the outer circumferential surface of the drum 30. So as to block the space between the drum 30 and the tub 20 through which the air passes. The direction in which the tub rib 720 extends may be any direction as long as it faces the drum 30, but in the direction of the shortest distance from the point where the tub rib 720 starts to the drum 30 It is preferable to extend it. This is because the maximum amount of space can be avoided with a minimum amount of material.

However, it is preferable that the tub rib 720 is extended to the outer circumferential surface of the drum 30 so as not to contact the drum 30. The tub rib 720 preferably has a length shorter than the shortest distance between the inner circumferential surface of the tub 20 and the drum 30. [

This is because the drum 30 rotates irrespective of the tub 20 and interrupts the rotation of the drum 30 when the tub rib 720 is extended enough to contact the drum 30. Also, it is preferable that the length of the tub rib 720 is adjusted to such a degree that unbalance occurs during rotation of the drum 30 to cause vibration, and the drum 30 does not contact the drum 30 even if the vibration occurs.

The tub ribs 720 may also be provided in a plurality of spaces. The resistance of the air flow path between the tub 20 and the drum 30 can be increased as a plurality of the tubular main surface 230 are provided along the inside of the tubular surface 220 or the tubular main surface 230. Further, the plurality of tub ribs 720 may be successively connected to further increase the resistance of the air flow path.

Fig. 5 shows the drum rib 730. Fig. The drum rib 730 is provided on the outer peripheral surface of the drum 30. In an embodiment of the present invention, a drum rib 730 is provided on the outer peripheral surface of the drum front surface 320 in the outer peripheral surface of the drum 30. In addition, the drum rib 730 may be provided on the outer circumferential surface of the drum circumferential surface 330 or on the outer circumferential surface of the drum opening 310.

The drum rib 730 also functions to prevent the inflow of air that has passed through the first communicating part 610 and the tub opening 210 in order to enter the space between the tub 20 and the drum 30. [ That is, it may serve to increase the resistance of the air passage between the tub 20 and the drum 30, such as the tub rib 720.

The drum rib 730 extends toward the inner circumferential surface of the tub 30. So as to block the space between the drum 30 and the tub 20 through which the air passes. The direction in which the drum rib 730 extends may be any direction as long as it faces the tub 30, but in the direction of the shortest distance from the starting point of the drum rib 730 to the tub 30 It is preferable to extend it. This is because the maximum amount of space can be avoided with a minimum amount of material.

However, it is preferable that the drum ribs 730 extend toward the inner circumferential surface of the tub 20 so as not to contact the tub 20. The drum rib 730 preferably has a shorter length than the shortest distance between the outer circumferential surface of the drum 30 and the tub 20.

This is because the drum 30 rotates irrespective of the tub 20 and interrupts the rotation of the drum 30 when the drum rib 730 is extended enough to contact the tub 20. In addition, unbalance of the laundry may occur in the drum 30 during the rotation of the drum 30, and vibration may be generated. The drum rib 730 may be adjusted to such a degree that the drum 30 does not contact the tub 20 .

Meanwhile, a plurality of drum ribs 730 may also be provided. The resistance of the air passage between the drum 30 and the tub 20 can be increased as a plurality of the drum 30 is provided along the outer circumferential surface of the drum front surface 320 or the drum circumferential surface 330. Further, the plurality of drum ribs 730 may be continuously densified to increase the resistance of the air flow path more densely.

FIG. 6 shows a view including the gasket rib 710, the tub rib 720, and the drum rib 730 all together. Concretely, the relationship between the tub rib 720 and the drum rib 730 will be described.

The tub rib 720 and the drum rib 730 may be provided so as to intersect with each other based on the flow of air. Since the tub rib 720 is connected to the tub 20 and the drum rib 730 is connected to the drum 30, an air flow path such as a maze can be formed between the tub 20 and the drum 30.

The total length of one of the tub ribs 720 and one of the drum ribs 730 is preferably longer than the shortest distance between the tub 20 and the drum 30. 6, a portion where the tub rib 720 and the drum rib 730 overlap with each other is formed on the basis of the direction in which air flows between the tub 20 and the drum 30. In other words, the air can not flow linearly in the space between the tub 20 and the drum 30, and the air flow path becomes longer due to the arrangement and length of the tub rib 720 and the drum rib 730 Lays. That is, the resistance of the air passage between the tub 20 and the drum 30 becomes extremely high.

The lengths of the tub rib 720 and the drum rib 730 have been described above in order to prevent the tub 30 from contacting the tub 20 due to the vibration generated when the drum 30 is rotated by the driving unit. When the tub ribs 720 and the drum ribs 730 are crossed and installed on the tub 20 and the drum 30 respectively, the same effect as that of extending the tub ribs 720 or the drum ribs 730 is obtained have.

On the other hand, when the tubular rib 720, the drum rib 730, and the gasket rib 710 are all used, the air flow path resistance becomes maximum, so that a considerable number of the air introduced through the first communication portion 610 flows through the ribs 70 will be directly supplied to the laundry through the drum opening 310 as compared with the conventional structure.

The ribs 70 are preferably made of a material having elasticity. Even if the minimum safety length is secured in consideration of the distance between the tub 20 and the drum 30 and the like, the vibration of the drum 30 can be extremely large instantaneously inevitably, 30 and the rib 70 may collide with each other.

Therefore, in order to minimize the damage to the surface of the drum 30 even if the drum 30 and the rib 70 collide with each other, and to minimize the influence on the rotation of the drum 30, And a material having high elasticity is preferable.

7 shows that the second communication portion 630 of the air circulation passage 60 protrudes from the tub 20 to the outer peripheral surface of the drum 30 by a predetermined distance.

When the second communicating part 630 protrudes toward the outer circumferential surface of the drum 30, air in the larger amount of the drum 30 flows into the second communicating part 630. The air inside the drum 30 flows into the second communicating part 630 through the through hole 31 provided in the drum 30.

A predetermined amount of air introduced into the space between the tub 20 and the drum 30 in order of the first communicating part 610 and the tub opening 210 passes through the second communicating part 630 And the air in the space between the tub 20 and the drum 30 becomes more difficult to flow out to the second communication part 630. [

The length of the second communicating portion 630 protruding toward the outer peripheral surface of the drum 30 is also shorter than the shortest distance between the tub 20 and the drum 30. [ This is because the drum 30 and the second communication portion 630 must not contact each other due to vibration generated when the drum 30 rotates.

The present invention may be embodied in various forms without departing from the scope of the invention. Accordingly, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
