As shown in fig. 1 to 10, the present embodiment discloses a wall-mounted washing machine including a tub 1, a drain device, an overflow pipe 51, the drain device including:

the drain valve component is communicated with the outer barrel 1 and discharges water in the outer barrel 1;

a drain pipe 3 for discharging the water discharged from the drain valve assembly to the outside of the washing machine;

and a drain tee structure 4 for communicating the drain valve assembly, the overflow pipe 51 and the drain pipe 3.

In the above scheme, the wall-mounted washing machine is different from a common drum washing machine in that the wall-mounted washing machine is arranged on a plane, and the wall-mounted washing machine is used by being hung on a wall. The wall-mounted washing machine comprises a drainage device, wherein the drainage device comprises a drainage valve assembly which forcibly discharges water in an outer cylinder 1 from the inside of the outer cylinder 1 to the outside in a corresponding washing stage, the water which is forcibly discharged out of the outer cylinder 1 is discharged out of the washing machine through a drainage pipe 3, and the drainage pipe 3 is a hose which is generally used for finally discharging the water out of the washing machine, so that the damage caused by vibration, collision and the like is easy to occur. The wall-mounted washing machine generally further includes a ventilation device 5 for ventilating air between the inside and the outside of the tub 1 to prevent the tub 1 from being damaged due to the inability to ventilate. The ventilating device 5 includes an overflow pipe 51, which can discharge the foam and water overflowing from the inside of the outer tub 1 to the outside of the washing machine, and can ventilate the inside of the outer tub 1. The drainage hose of the common wall-mounted washing machine extends to the outside of the washing machine after penetrating through the rear panel, and plays a role in fixing by penetrating through the rear panel, but the hose is damaged due to the fact that sharp edges or rib structures possibly existing on the edge of a hole in the rear panel damage the hose when the hose vibrates, and the damage rate of the hose is high. Generally, the overflow pipe 51 overflows the water in the outer cylinder 1 from the overflow pipe 51 to the outside of the washing machine when the washing machine works abnormally, but if the overflow pipe 51 is directly connected to the outside of the washing machine and the drain pipe 3 is also connected to the outside of the washing machine, a plurality of components are arranged. In addition, when the overflow pipe 51 is directly connected to the drain pipe 3, the drain pipe 3 is a hose, which may cause leakage or shaking and detachment. The invention relates to a drainage device of a wall-mounted washing machine, which solves the problem and also comprises a drainage three-way structure 4 for fixing a drainage pipe 3 and an overflow pipe 51 and preventing the drainage pipe 3 and the overflow pipe 51 from shaking and vibrating during drainage.

Further, the drainage three-way structure 4 includes:

a water inlet end 41, wherein one end of the water inlet end 41 is communicated with the drain valve assembly;

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 51 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 51 can be fixedly supported, and the water outlet pipe 3 and the overflow pipe 51 are prevented from shaking and vibrating during water drainage.
