And the water inlet valve is used for injecting water into the inner and outer barrel assemblies of the washing machine to clean clothes.

In the embodiment of the present invention, the outer barrel 11 and the inner barrel 12 are integrally a circular barrel, the inner barrel 12 is nested in the outer barrel 11, the inner barrel 12 is provided with a plurality of through holes, so that the outer barrel 11 and the inner barrel 12 are communicated, referring to fig. 2, the circular outer barrel 11 surrounds the circular inner barrel 12, the outer wall of the outer barrel 11 is provided with the overflow gap 2, and the water flowing into the overflow gap 2 is discharged out of the washing machine through the drain pipe.

The overflow port 2 is a cavity independently arranged on the outer wall of the outer barrel 11, correspondingly, the outer barrel 11 is provided with an opening at the position corresponding to the overflow port 2, so that the overflow port 2 is communicated with the inside of the inner and outer barrel assemblies, and when the washing machine works abnormally, and water is continuously injected into the inner and outer barrel assemblies, excessive water in the inner and outer barrel assemblies flows into the overflow port 2.

The overflow 2 has a prism shape as a whole, and the opening of the outer tub 11 corresponding to the overflow 2 has a rectangular opening so that the overflow 2 is fixed to the outer wall of the outer tub 11.

In order to make the water in the inner and outer barrel assembly flow into the overflow gap 2, the opening of the outer wall 11 at the overflow gap 2 is provided with a first water guiding rib 21 and a second water guiding rib 22, referring to fig. 3, the edge of the first water guiding rib 21 close to the inner barrel 12 is attached to the inner wall of the outer barrel 11, so that the outer barrel 11 is in a circular shape, and the second water guiding rib 22 is arranged at the position of the overflow gap 2 close to the inner side of the overflow gap 2, so that the first water guiding rib 21 and the second water guiding rib 22 form an interval in the radial direction.

The first water guiding rib 21 and the second water guiding rib 22 have the same shape and are both arc-shaped structures, so that the overflow gap 23 formed at the interval between the first water guiding rib 21 and the second water guiding rib 22 is also arc-shaped structure.

When the inner barrel 12 of the pulsator washing machine rotates at a high speed, water in the inner and outer barrel assemblies is acted by centrifugal force and ascends along the inner wall of the outer barrel 11, and when the washing machine works normally, the water in the inner and outer barrel assemblies cannot reach the height of the overflow opening 2 generally, and even if the water reaches the height of the overflow opening 2, the water is blocked by the first water guide ribs 21 and cannot flow into the overflow opening 2, so that the waste of water resources is reduced.

When the washing machine works abnormally, when water is continuously injected into the inner and outer barrel assemblies of the washing machine, the water in the inner and outer barrel assemblies is excessive, an arc-shaped overflow gap 23 is formed between the first water guide rib 21 and the second water guide rib 22 and serves as a channel for water to flow into the overflow opening 2, and the water flows into the overflow opening 2 along with the arc-shaped overflow gap 23, so that when the washing machine works abnormally, the internal parts of the washing machine and the motor 4 are protected from working normally.

In order to further improve the water guiding function and the water retaining function of the first water guiding rib 21 and the second water guiding rib 22, the end portion of the first water guiding rib 21 close to the second water guiding rib 22 is an acute angle, and similarly, the end portion of the second water guiding rib 22 close to the first water guiding rib 21 is an acute angle.

One side of the first water guiding rib 21 close to the inner tub 12 is longer than one side of the first water guiding rib 21 close to the second water guiding rib 22, so that an acute angle is formed at the joint of the tail ends of the first water guiding ribs 21, and one end of the acute angle of the first water guiding rib 21 is located at the inlet position of the overflow gap 23, as the inner tub 12 rotates, water flows tightly cling to the wall of the outer tub 11 to climb up, and one end of the first water guiding rib 21 is an acute angle, when the washing machine works abnormally, excessive water flow in the inner and outer tub assemblies is introduced into the overflow gap 23, so that the water flow on the wall of the outer tub 11 is ensured to flow into the overflow port 2 through the overflow gap 23, and the water is prevented from flowing into parts and the motor 4.

One side of the second water guiding rib 22 close to the overflow opening 2 is longer than one side of the second water guiding rib 22 close to the first water guiding rib 21, so that an acute angle is formed at the joint of the tail end of the second water guiding rib 22, and one end of the acute angle of the second water guiding rib 22 is located at the outlet position of the overflow gap 23, therefore, the inclined edge of the one end of the acute angle of the second water guiding rib 22 is close to the overflow gap 23, water flowing out of the overflow gap 23 flows into the overflow opening 2 along the inclined edge of the one end of the acute angle of the second water guiding rib 22, and water flow is prevented from sputtering.

Referring to fig. 4 and 5, in the embodiment of the present invention, the first water guiding rib 21 and the second water guiding rib 22 have the same height and are slightly higher than the height of the overflow gap 2, so as to ensure that the overflow gap 23 has a sufficient height for water circulation.

The outer tub 11 and the inner tub 12 of the pulsator washing machine have a large volume and thus have a high height, and when the washing machine is abnormally operated and water is continuously supplied into the inner and outer tub assemblies, the amount of water remaining in the inner and outer tub assemblies is excessive, so that the overflow gap 2 needs to have a sufficient flow area to ensure that the water completely flows into the overflow gap 2.

Therefore, the height of the first water guiding rib 21 and the second water guiding rib 22 is set to exceed the height of the overflow opening 2, so as to ensure that the height of the overflow gap 23 is enough to enable the water in the inner and outer tub assemblies to flow into the overflow opening 2, and protect the internal components of the washing machine and the motor 4.

The first water guide rib 21 and the second water guide rib 22 are integrally formed with the outer tub 11, and since the area of the overflow gap 23 between the first water guide rib 21 and the second water guide rib 22 is large, the position where the outer tub 11 is connected with the first water guide rib 21 and the second water guide rib 22 is in arc transition, so that the stress concentration of the outer tub 11 at the position where the first water guide rib 21 and the second water guide rib 22 are connected is prevented.

When the circulating water function of the pulsator washing machine is started, the inner barrel 12 rotates to drive water in the barrel to climb upwards along the inner wall of the outer barrel 11 clockwise, the climbing direction of the inlet of the overflow gap 23 corresponding to water flow is correspondingly arranged, and the water flow is prevented from flowing into the overflow port 3 through the overflow gap 23 when the washing machine works normally, so that water resource waste is caused.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

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.
