Background

At the present stage, the living standard of people is continuously improved, and the requirements for washing and protecting clothes are more and more abundant and detailed. Separate washing of laundry is increasingly sought after by users. However, two washing machines are needed for separately washing clothes, but the space of the existing home environment is generally small, the two washing machines are difficult to accommodate, and the common washing machine has a large volume and occupies a large space of a home, so that the wall-mounted washing machine capable of being mounted on a wall is more and more favored by people.

At present, the drain pipes of most of washing machines including wall-mounted washing machines are inserted into the drain outlets and are fixed by pipe clamps and the like, when the drain pipes are pulled or not mounted in place, the drain pipes can fall off carelessly, and at the moment, if the washing machines operate, water can flow around to cause use troubles.

Chinese patent application No. 201310337301.9 discloses a wall-mounted drum type washing machine including: a drain device including a drain hole formed at a bottom of the tub; a drain pump installed under the tub and forcibly draining the washing machine water in the tub through the drain hole; and a drain pipe having a section connected to the drain pump and extending to the outside through the rear panel. However, when the drain pipe is pulled or not installed properly and falls off accidentally, if the washing machine is operated, water will flow around, causing troubles in use.

Chinese patent application No. 201310433716.6 discloses a washing machine comprising: a rear panel mounted on a wall; a tub supported by the rear panel and containing washing water; a front panel on or in front of the tub having an opening therein; a rotatable drum within the tub; a driving unit supplying power to the drum; a cover on the rear panel covering the tub and the front panel; a water supply device for supplying washing water to the tub; and a drain device having a drain filter on the washing water discharge path for filtering out foreign matters in the washing water discharged to the outside of the tub and then flowing to the drain hose. The drain hose is connected to the drain filter and extends to the outside of the washing machine through the rear panel. However, in the wall-mounted washing machine without a rear panel, the drain hose cannot be connected and fixed, and vibration is likely to cause collision during draining, which is likely to cause damage and splashing of drained water. However, when the drain pipe is pulled or not installed properly and falls off accidentally, if the washing machine is operated, water will flow around, causing troubles in use.

In view of the above, the present invention is particularly proposed.

Further, the other end of the water outlet end 43 not communicating with the water outlet pipe 3 is connected to the water inlet end 41, and the other end of the overflow end 42 not communicating with the overflow pipe 2 is connected to the water outlet end 43. The water outlet end 43 is connected to the other end of the water inlet end 41 which is not communicated with the drain valve assembly, and the overflow end 42 is connected to the other end of the water outlet end 43 which is not communicated with the drain pipe 3. The connection mode among the water outlet end 43, the overflow end 42 and the water inlet end 41 enables the drainage tee joint structure 4 to be compact and small in occupied space.

Further, the other end of the water inlet end 41, which is not communicated with the drain valve assembly, extends towards the wall and is connected to one end of the outer barrel 1, which is close to the wall. The water outlet end 43 and the overflow end 42 of the three-way drainage structure 4 are closer to the rear end of the washing machine, so that the drainage pipe 3 connected with the water outlet end 43 can be hidden conveniently, and the overflow pipe 2 can be installed conveniently.

Furthermore, the water inlet end 41 is a hard tubular structure, and the water outlet pipe 3 communicated with the water outlet end 43 and the overflow pipe 2 communicated with the overflow end 42 are fixedly supported at one end of the outer cylinder 1 close to the wall. The water can be smoothly discharged after being led out to the rear side of the outer barrel 1, so that the drain pipe 3 is prevented from being exposed and not attractive due to the fact that the drain pipe 3 is arranged at the front end of the outer barrel 1, and the drain hose is prevented from being damaged due to shaking and vibration caused by incapability of fixing in the process of connecting the drain hose and a floor drain; in addition, the water inlet end 41 is of a hard tubular structure, so that the water outlet pipe 3 and the overflow pipe 2 can be fixedly supported, and the water outlet pipe 3 and the overflow pipe 2 are prevented from shaking and vibrating during water drainage.

Further, the other end of the water inlet end 41 gradually extends downward toward the wall. So that the water in the water inlet end 41 cannot flow back to the drain valve assembly or accumulate in the water inlet end 41 and cannot be drained completely.

Further, the water outlet end 43 is connected to the lowest portion of the water inlet end 41 and extends vertically downward.

In the above scheme, the water in the water inlet end 41 can be completely drained without residue, the water outlet end 43 extending vertically downwards is more suitable for draining water, the water can be completely drained under the action of gravity, and resources are saved without external force.

Furthermore, the overflow end 42 is inclined to the water outlet end 43, and the connection between the overflow end 42 and the water outlet end 43 is the lowest position of the overflow end 42. So that the water in the overflow end 42 will not flow back to the overflow pipe 2, or the water stored in the overflow end 42 can not be discharged completely without residue,

furthermore, reinforcing ribs 44 for increasing the connection strength are arranged between the water outlet end 43 and the water inlet end 41, and between the water inlet end 41 and the overflow end 42.

In a further preferred embodiment, the rear wall of the outer cylinder 1 is provided with an exhaust hole communicated with the inside of the outer cylinder 1, the overflow pipe 2 is arranged at the rear part of the outer cylinder 1, one end of the overflow pipe is communicated with the inside of the outer cylinder 1 through the exhaust hole, the other end of the overflow pipe is communicated with the drainage three-way structure 4,

preferably, one end of the overflow pipe 2 is communicated with the highest water level inside the outer cylinder 1 through an exhaust hole, and the other end is communicated with the water outlet end 43 of the drainage three-way structure 4.

The overflow pipe 2 is arranged at the rear part of the outer barrel 1, so that the space at the side part of the outer barrel 1 is saved compared with the space at the side part of the outer barrel 1, the volume of the wall-mounted washing machine is reduced, and the overflow pipe 2 can be arranged between rib structures at the rear wall of the outer barrel 1 and does not occupy more space at the rear wall of the outer barrel 1. The rear wall of the outer barrel 1 comprises an exhaust hole communicated with the interior of the outer barrel 1, the exhaust hole is formed in the rear wall of the outer barrel 1, and the overflow pipe 2 is conveniently connected to the rear wall of the outer barrel 1. One end of the overflow pipe 2 is communicated with an exhaust hole arranged above the rear wall of the outer cylinder 1, the other end is communicated with a drainage device, and the foam and the water overflowing from the upper part of the outer cylinder 1 are discharged out of the washing machine through the drainage device. In a preferred embodiment, the overflow pipe 2 is communicated with the highest water level in the outer cylinder 1 through an exhaust hole, so that the problems of foam and water accidental overflow caused by the lower position of the exhaust hole and further incomplete washing and the like are avoided.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
