An overflow gap 27 is further formed between the skirt 21 and the outer tub cover 2, the position of the overflow gap 27 corresponds to the position of the overflow opening 111 of the outer tub 11, and when the outer tub cover 2 is mounted on the upper end of the outer tub 11, the overflow gap 27 corresponds to the overflow opening 111.

The overflow notch 27 may be provided in a plurality on the outer tub cover 2, and in this embodiment, the number of the overflow notch 27 is one.

The overflow port 23 on the overflow channel 21 has a short interval at the overflow gap 27, so that the overflow port 23 is relatively dense at the overflow gap 27, when the washing machine fails, the water level in the tub continuously rises, when the water level exceeds the height of the outer tub cover 2 of the washing machine, the water exceeding the outer tub cover 2 flows into the overflow channel 22 through the hollow part between the overflow port 23 and the outer tub cover 2, and the overflow channel 22 is a groove, so that the water can circulate in the overflow channel 22.

An overflow gap 27 is formed between the baffle 21 and the outer barrel cover 2, when the water in the overflow channel 22 passes through the overflow gap 27, the water will not be blocked by the baffle 21, and flows downwards into the overflow gap 111 through the overflow gap 27, and flows to the drain pipe in the overflow gap 111 to be discharged out of the barrel.

The bottom surface of the outer barrel cover 2 is provided with a water baffle 24, one end of the water baffle 24 is connected with one end of the overflow port 23, the other end of the water baffle 24 faces the lower part of the outer barrel cover 2, an opening 25 is formed between the water baffle 24 and the overflow port 23, when the washing machine normally works, the inner barrel 12 rotates to drive water flow in the barrel to rotate, water flow (arrows in the figure represent water flow), when the water flow climbs along the inner wall of the outer barrel 11, the water flow climbed is blocked by the water baffle 24 to prevent the water flow from entering the overflow channel 22, but the overflow channel 22 is a circle of groove surrounding the outer barrel cover 2, even if a small part of water flow enters the overflow channel 22, the water flow can flow into the barrel again through the overflow ports 23 at other positions, and waste of water resources is.

In order to improve the strength of the outer barrel cover 2, a plurality of flow guiding ribs 26 are circumferentially arranged at intervals at the lower end of the outer barrel cover 2, referring to fig. 4 and 6, the upper ends of the flow guiding ribs 26 are connected with the lower end of the outer barrel cover 2, the rear end face is connected with the surrounding baffle 21, the front end face extends to the inner side hollow part of the outer barrel cover 2, and in this embodiment, the bottom face of the flow guiding ribs 26 is an arc face.

Further, referring to fig. 3, 6 and 7, the overflow opening 111 of the outer tub 11 of the washing machine is triangular at a portion beyond the outer tub 11, and correspondingly, the overflow notch 27 formed by the baffle 21 and the outer tub cover 2 is also triangular, so that the overflow notch 27 is nested in the overflow opening 111.

The outer barrel cover 2 is provided with a bulge in the overflow gap 27, the bulge and the outer barrel cover 2 form an overflow channel 28 communicated with the overflow channel 22, the overflow channel 28 vertically penetrates through the outer barrel cover 2, correspondingly, an outer barrel flow channel is arranged in the overflow port 111 of the outer barrel 2 corresponding to the overflow channel 28, water is guided to the overflow gap 27 through the overflow channel 22, flows downwards into the overflow port 111 of the outer barrel 11 through the overflow channel 28, and finally flows into a drain pipe through the outer barrel flow channel and is discharged out of the barrel.

When the washing machine sprays water to the inner side of the inner barrel 12, the water directly flows into the barrel through the hollow part of the outer barrel cover 2, at the moment, the inner barrel 12 rotates to clean clothes in the barrel, water flow rotates in the barrel under the driving of the inner barrel 12, due to the spraying water, the water which just falls down can jump under the driving of the water flow, and after the water meets the water baffle plate 24 and the flow guide rib 26 of the outer barrel cover 2, the water falls into the barrel again, and the waste of water resources is reduced.

The outer barrel cover 2 provided by the embodiment is arranged at the upper end of the outer barrel 11 of the washing machine, when the inner barrel 12 rotates and drives a large amount of water flow in the barrel to rotate, the water baffle 24 and the flow guiding ribs 26 can effectively prevent the water flow from entering the overflow channel 22, the flow channel overflow port 111 is discharged out of the barrel, and water resource waste is caused; meanwhile, when the washing machine breaks down, water in the tub is continuously injected, and the water level is continuously increased, the water exceeding the outer tub cover 2 enters the overflow channel 22, flows into the overflow channel 28 at the overflow notch 27 under the diversion effect of the overflow channel 22, falls into the overflow port 111 of the outer tub 11, and discharges redundant water out of the tub, so that the washing machine is ensured to have a normal overflow function, meanwhile, the waste of water resources is not caused, and the cost of a user is saved.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
