By providing the water collecting device, when water is discharged from the inner tub 200, the water thrown out when water is dehydrated in the inner tub 200 is collected by the water collecting device to prevent the water from overflowing, and on the other hand, the water collecting device can be integrally provided at the lower portion of the bottom of the inner tub 200. Since the whole water collecting device is positioned below the inner tub 200, the water collecting device does not occupy the space between the inner tub 200 and the cabinet 100, and has no limitation on the expansion of the inner tub 200, thereby providing a sufficient space for the expansion of the inner tub 200.

In a further aspect, the water collecting device includes a water collecting chamber 400 having an upper opening, the inner barrel 200 is communicated with the upper opening of the water collecting chamber 400, and a shock absorbing device 800 is disposed outside a sidewall of the water collecting chamber 400.

Through setting up water collecting cavity 400, can enough collect the water that dewaters in interior bucket 200 and throw away, can realize blockking again the interior exhaust water of bucket 200. The side wall of the water collecting chamber 400 may be flush with the outer wall of the inner tub 200, not occupying the space between the inner tub 200 and the cabinet 100; the upper end of the side wall of the water collecting cavity 400 can also be lower than the bottom of the inner barrel 200, so that the water collecting cavity 400 is wholly positioned below the bottom of the inner barrel 200, and further, the side wall of the water collecting cavity 400 does not have a structure positioned between the inner barrel 200 and the box body 100, so that the barrel diameter of the inner barrel 200 can be greatly increased, the capacity expansion of the inner barrel 200 can be better realized, a certain safety distance does not need to be arranged between the inner barrel 200 and a water collecting device, and the inner barrel 200 is prevented from colliding with the water collecting device to cause damage. At the same time, the possibility of the water collecting device hitting the cabinet 100 is further reduced.

The shock-absorbing device 800 is disposed outside the sidewall of the water collecting chamber 400, which can provide a guarantee for further reducing the damage of the washing machine accidentally hitting the tub. Damping device 800 can play the cushioning effect when taking place the accident of water-collecting device striking box 100, provides protection or secondary protection, can make no matter water-collecting device wholly sets up in interior bucket 200 bottom, still lateral wall and interior bucket 200 lateral wall parallel and level, can both play further cushioning effect.

The upper end of the side wall of the water collecting cavity 400 is lower than the bottom of the inner barrel 200, and a certain distance is formed between the side wall of the water collecting cavity 400 and the outer wall of the bottom of the inner barrel 200, so that the inner barrel 200 is prevented from colliding with the side wall of the water collecting cavity 400 when vibrating, and the service life of the water collecting cavity 400 is prolonged.

The water collecting cavity 400 is provided with a drain pipe 401 for draining water in the water collecting device, and the drain pipe 401 extends out of the washing machine.

The inner tub 200 includes a first drain port 201 for draining water when spin-drying, and a first drain line 202 communicated with the first drain port 201, and a water outlet 203 of the first drain line 202 is communicated with a water collecting device. The first drain pipe 202 connected to the first drain port 201 drains the water in the inner tub 200 into the water collecting device, and further drains the water through the drain pipe 401.

Example two

As shown in fig. 5 and 6, this embodiment is further limited to the first embodiment, in this embodiment, the water collecting device includes a mounting plate and a water blocking rib 501 disposed on the mounting plate, the mounting plate and the water blocking rib 501 enclose to form a water collecting cavity 400, and a shock absorbing device 800 is disposed on an outer wall of the water blocking rib 501.

Through setting up mounting panel 500 and manger plate muscle 501 to make the two enclose and close formation chamber 400 that catchments, this simple structure, the machine-shaping of being convenient for. The lateral wall that manger plate muscle 501 was catchmented the chamber 400, has certain height, and is nearer apart from box 100, has the possibility of striking box 100, sets up damping device 800 on manger plate muscle 501's outer wall, vibrations when can reducing manger plate muscle 501 accident striking box 100 avoid causing the harm. Directly fixed damping device 800 can on the fender muscle in the production process, need not measure the position that box 100 and fender muscle correspond, damping device 800 can be along with manger plate muscle 501 combined activity all the time, can not take place skew accident, and damping device 800 can exert the biggest effect.

The water collecting chamber 400 is located at the middle of the mounting plate 500, so that the center of gravity of the water blocking device is more easily coincided with the center, and the deviation is reduced.

The water retaining rib 501 is annular, and the water retaining rib 501 and the mounting plate 500 enclose to form an annular water collecting cavity 400.

In a further scheme, the damping device 800 is arranged at a position on the water blocking rib 501, which has the smallest distance from the inner wall of the box body 100.

In order to achieve a good water accumulation effect and reduce occupied space, the water retaining rib 501 needs to be matched with the bottom of the inner barrel 200 for annular arrangement; the cabinet 100 of the washing machine is generally square, so the distances between different positions of the water blocking rib 501 and the inner wall of the cabinet 100 are different. The tangent line of the outer periphery of the annular water blocking rib 501 is parallel to the side wall of the box body 100, that is, the part where the distance between the water blocking rib 501 and the inner wall of the box body 100 is the smallest. The shock absorbing devices 800 can be arranged at intervals and are only arranged at the positions, with the minimum distance, of the water blocking ribs 501 and the inner wall of the box body 100, so that the cost is reduced, and a good shock absorbing effect is achieved. Alternatively, the damping device 800 may be disposed at a position having the smallest distance from the inner wall of the casing 100, or the damping device 800 may be disposed at other positions, or all of them, so as to achieve a damping effect in more directions.

The arrangement of the shock-absorbing devices 800 on the water collecting device and the inner barrel 200 can select to be arranged on the water collecting device or the outer wall of the inner barrel 200 according to the position relation between the water collecting device and the inner barrel 200, or arranged on the outer walls of the water collecting device and the inner barrel 200, so as to achieve the best shock-absorbing effect with low cost. The setting can be made as follows:

Case 1: when the horizontal projection of the inner tub 200 covers the horizontal projection of the water collecting chamber 400, the shock-absorbing device 800 is disposed on the outer wall of the inner tub 200.

The projection of the inner barrel 200 in the horizontal direction covers the projection of the water collecting cavity 400 in the horizontal direction, so that the interval between the water collecting cavity 400 and the box body 100 is increased, the collision of the water collecting cavity 400 to the box body 100 can be prevented, and the damage of the water collecting cavity 400 is reduced; meanwhile, the water collecting chamber 400 is small, which is more convenient for installing other devices at the bottom of the box body 100.

When the projection of the inner barrel 200 in the horizontal direction covers the projection of the water collecting cavity 400 in the horizontal direction, the water collecting device is completely positioned at the bottom of the inner barrel 200, and the diameter of the water collecting device is smaller than that of the inner barrel 200, compared with the case that the inner barrel 200 has a large diameter and a high height, the water collecting device is more likely to impact the box body 100 during vibration, therefore, the damping device 800 can be arranged on the outer wall of the inner barrel 200, and the position closest to the box body 100 can be selected for blocking arrangement, continuous arrangement or arrangement in a large area as possible. The side wall of the water collecting chamber 400 is less likely to collide against the tank 100 and may not be provided.

Case 2: when the horizontal projection of the inner tub 200 is located inside the horizontal projection of the water collecting chamber 400, the shock-absorbing device 800 is disposed on the outer wall of the inner tub 200 and the outer wall of the water blocking rib 501.

When the horizontal projection of the inner tub 200 is located inside the horizontal projection of the water collecting chamber 400, the side wall of the water collecting chamber 400, such as the diameter of the water blocking rib 501 is larger than the diameter of the inner tub 200, and is closer to the case 100, so that the possibility of the accident of tub collision is higher, and the height of the inner tub 200 is higher, so that the swing amplitude of the inner tub 200 is also larger during vibration, and the accident of tub collision may also occur. Therefore, the outer wall of the inner tub 200 and the outer wall of the water blocking rib 501 may be provided with the damper 800, or only the outer wall of the water blocking rib 501 may be provided with the damper 800.

In a further scheme, the water retaining rib 501 is obliquely arranged and gradually shrinks towards the central axis direction of the water collecting cavity 400 from top to bottom, and the damping device 800 is arranged at the upper part of the periphery of the water retaining rib 501;

the water retaining rib 501 is arranged to be inclined, so that the water collecting amount can be increased to the maximum extent, and the water retaining rib is more convenient to use; at this time, the distance between the upper portion of the water blocking rib 501 at the same position and the box body 100 is greater than the distance between the middle portion and the lower portion of the water blocking rib 501 and the box body 100, and at this time, the shock absorbing device 800 needs to be arranged on the upper portion of the outer side wall of the water blocking rib 501, so that the effect of reducing shock is achieved.

Or, the water blocking rib 501 is vertically arranged, and the damping device 800 is arranged in the middle and/or the upper part of the periphery of the water blocking rib 501. When the water blocking rib 501 is vertically arranged, the process is simple, the preparation is easy, at the moment, the distance between the water blocking rib 501 at the same position and the box body 100 is the same, the vibration amplitude of the position with high position is considered to be larger, and the damping device 800 is arranged at the upper part and/or the middle part of the vertical water blocking rib 501.
