Description

Sweeper

The present invention relates to a cleaning machine, and more specifically, to a vacuum cleaning machine.

Generally speaking, a sweeper is a device for discharging air from the main body of the sweeper. It sucks in external air containing particles such as dust by the negative pressure generated by a fan installed in the main body, filters out the particles, and then removes the air from the main body. Exhaust the air.

According to the type of power supply, the cleaning machine can be mainly classified into: a wired cleaning machine with power supplied from a power outlet, which uses an electric wire extending from the main body to the outside; and a wireless cleaning machine with a secondary battery installed in itself .

The first cyclone effect occurs in the first chamber 431, and the second cyclone effect may occur in the second chamber 433.

Referring to FIG. 3 and FIG. 4 showing a cross-section along the line B-B' of FIG. 3, the configuration related to the first cyclone effect occurring in the first chamber 431 will be described below.

First, the center of the air inlet 12 is set to be inclined to the right or left within a specified range with respect to the longitudinal axis of the air inlet pipe 31. Therefore, the air flowing into the first chamber 431 can follow the outer side of the chamber housing 43. The circumferential surface rotates naturally.

The air intake member 30 may further include an air intake pipe connecting portion 32 that connects the air intake pipe 31 to the first housing 10, and a rotation guide 33 that guides air to the air intake port 12 may be installed at the air intake pipe connecting portion 32 Inside.

In addition, a dust discharge port 51 c formed as an open plane may be formed on the bottom side of each of the plurality of flow path main bodies 51.

According to the above configuration, in the cyclone forming member 50, the second cyclone effect occurs as air flows into the inflow port 51b, and then the blade 55 rotates along the dust separation flow path 51a and descends. After that, the air will rise along the riser 53.

As a result, the dust contained in the air cannot flow into the rising pipe 53 due to its own weight, but is discharged from the flow path main body 51 through the dust discharge port 51c.

The plurality of flow path main bodies 51 may be connected to each other through the connecting plate 57. Also, the connecting plate 57 may be configured in a disc shape corresponding to the inner circumferential shape of the chamber housing 43.

In addition, the dust separation member 46 also has a function of preventing the air in the first chamber 431 from being sucked into the dust discharge port 51c. To this end, the top side of the dust separation part 46 is covered by the connecting plate 57, and the bottom side of the dust separation part 46 may be sealed by the first housing cover 23 and the annular sealing rib 233 provided on the top side of the first housing cover 23 .

Here, in order to ensure the airtightness of the bottom side of the dust separating member 46, the sealing rib 233 is preferably formed of a flexible material.

In some implementations, the sweeper 1 according to an embodiment of the present invention may further include a partition 59 covering the top side of the second chamber 433, and the related configuration can be further understood with reference to FIGS. 3 and 4.

The partition 59 is disposed above the chamber housing 43, and the bottom side of the partition 59 may be configured in a cup shape that can cover the top side of the second chamber 433.

A plurality of riser pipe insertion holes 591 may be formed in the bottom side of the partition 59 so as to be respectively coupled with the protruding portions of the riser pipe 53.

The riser tube 53 is provided in a manner to protrude upward from the top side of the flow path main body 51 by a predetermined length for letting air flow into the dust separation flow path 51a, and a designated portion of the protruding portion may be connected to the bottom surface of the partition 59. The ascending pipe is inserted into the part of the hole 591.

A partition flange 593 extending a predetermined length in the circumferential direction may be formed on the top edge of the partition 59. The partition flange 593 is coupled to the partition support rib 102 in the first housing 10 so as to fix the partition 59 to the first housing 10.

The air rising in the rising pipe 53 through the fan 60 may pass through the first filter 93 of the filter member 90 and then flow into the second housing 16 through the housing communication hole 13. The details of the filter member 90 will be described below to facilitate understanding of the structure.

The fan 60 may mainly include: a fan housing 65, which forms the exterior of the fan 60 and enables the fan 60 to be installed in the second housing 16; an impeller 63, which is arranged in the fan housing 65 to allow air to flow; and a motor 61, which is arranged Inside the fan housing 65, the impeller 63 is provided with rotational power.

Therefore, if power is supplied to the motor 61, the impeller 63 can be rotated through the motor 61 so that air can flow into the rear side of the second housing 16.

The housing communication hole 13 is located above the partition 59. In this case, the air can flow into the fan housing 65 without passing through a complicatedly curved flow path.

Therefore, according to the above-described embodiment of the present invention, since the flow path resistance that may be generated by the complicatedly curved flow path of the peripheral portion of the motor 61 is reduced, the suction force or efficiency can be excellently improved.

In addition, since the fan housing air inlet 651 of the fan housing 65 is formed in the front side of the fan housing 65, the air that has flowed into the housing communication hole 13 can pass through the exhaust of the second housing cover 26 via the fan housing 65. The air hole 261 is discharged.

In this case, since the diameter of the fan housing air inflow port 651 is formed to be smaller than the diameter of the fan housing on the center line in the longitudinal direction, the suction force of the fan 60 can be maximized.

In addition, at least some of the plurality of exhaust holes 231 of the second housing cover 26 may be provided to face the fan housing 65 to reduce air resistance due to the closing plane of the second housing cover 26.

In addition, a fan housing support rib 165 protruding toward the center of the second housing 16 may be provided on the inner circumferential surface of the second housing 16 so as to fix the fan housing 65 to the second housing 16.

Also, the extension 76 may be connected to a lower part of the side of the battery box 86 that faces the handle body 73.

Therefore, as described above, since the center of gravity of the battery 83 is located right next to the user's gripping point of the handle body 73, and the center of gravity of the fan 60 is located directly above the user's hand, when the user moves the cleaning machine 1, Compared with the prior art, the torque applied to the hand is significantly reduced.

However, unlike the structure shown in FIG. 7, if only one space that can be grasped by the user can be formed, the handle body 73 may be configured to be aligned with the longitudinal axis A2 passing through the air intake pipe 31 and the first housing The plane of the longitudinal axis A1 of 10 intersects.

In addition, the battery box 86 and the second housing 16 may be disposed between two cut surfaces of the first housing 10 parallel to a plane perpendicular to the ground by passing through the longitudinal axis A2 of the air intake pipe 31.

In addition to the above features, when the center of gravity of the fan 60 is kept close to the handle body 73, the torque reduction effect is maximized.

The above-mentioned setting relationship is described in detail with reference to FIG. 8, which is a side view of the cleaning machine 1 according to an embodiment of the present invention.

The height of the battery box 86 may be set to be equal to or greater than half of the height of the first housing 10 and smaller than the height of the first housing 10, thereby it may be advantageous to expand the capacity of the battery.

That is, in the above structure, in order to comply with the expanded capacity of the battery 83, the higher the height of the battery box 86, the closer the center of gravity of the battery 83 is to the longitudinal center of the handle body 73.

Therefore, although the battery 83 is expanded with the same capacity, according to an embodiment of the present invention, compared with the prior art cleaner shown in FIG. 1, the moment of inertia relative to the longitudinal center of the handle body 73 will increase relatively small. .

In addition, the handle main body 73 may be configured to use one end of the handle main body 73 as an axis to be inclined at a specified angle in the forward direction by the longitudinal axis A2 passing through the air intake pipe 31 and the longitudinal axis of the handle main body 73 At least one angle α of the angles formed by the extension line of A3 is less than 90°.

Therefore, when the user tilts the air intake duct 31 forward to perform floor cleaning, the user can clean the floor naturally without excessively tilting the sweeper.

Meanwhile, the extension 76 can be configured in any shape that can be connected to the battery box 86. Preferably, the extension 76 is connected via the shortest path between one end of the handle body 73 and the side surface of the battery box 86.

Referring to FIG. 9, another embodiment of the battery box 86 and the battery 83 will be described below.

Unlike the previous embodiment, the battery box 86 may be configured to have a height equal to or less than half of the height of the first housing 10.

This embodiment is suitable for the case of reducing the size of the battery 83 and the battery box 86, and has the effect of compactly reducing the overall size and weight of the cleaning machine 1.

Next, another embodiment of the insertion structure of the battery box 86 of the battery 83 will be described with reference to FIG. 10.

However, since the foregoing embodiment can be configured in such a way that the battery 83 is inserted into/removed from the battery box 86, the common configuration for insertion/removal will be described first, and then the unique configuration of this embodiment will be described. .

First, as a configuration applicable to all the above-described embodiments, a battery receiving portion 861 into which the battery 83 can be inserted is formed in the battery box 86, and an open flat battery insertion port 863 can be formed on the rear side of the battery box 86.

Therefore, the battery 83 can be accommodated in the battery accommodating portion 861 in a manner of sliding from the rear side to the front side through the battery insertion port 863.

In addition, as a configuration applicable to all the foregoing embodiments, the battery 83 may include: a battery frame 831 that forms the exterior; a terminal 835 that transmits power to the motor 61; and a protrusion 833 that is provided with a terminal 835.

According to the present embodiment, the battery frame 831 may be arranged at a height equal to or less than 2/3 or 1/2 of the height of the battery receiving portion 861, and the cover portion 839 extending upward may be provided on the rear side of the battery frame 831 , To cover the battery insertion port 863.

Although the battery box 86 may be formed at a predetermined height, the battery 83 may be configured in various sizes such as a large storage battery and a small storage battery if necessary.

In the case of using a small storage battery, the designated portion of the battery insertion port 863 is kept in an open state.

Therefore, according to this embodiment, when the lid portion 839 covers the opening portion of the battery insertion port 863, dust can be prevented from flowing into the battery accommodating portion 861, and the beauty of the appearance can be enhanced.

Effects not disclosed in this specification can be additionally provided by the above-mentioned various configurations of the present invention. And, of course, it is possible to provide new effects in addition to the prior art based on the basic combination of the respective configurations described above.

It is obvious to those having ordinary knowledge in the technical field that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention. Therefore, the present invention is intended to cover modifications and changes within the scope of the patent application and its equivalents.
