Description

Technical Field

[0001] The utility model belongs to the technical field of washing equipment, and particularly relates to a bucket cover assembly of a washing equipment and a washing equipment with the bucket cover assembly. Background Art

[0002] At present, existing washing equipment that needs to be sealed, such as drum washing machines, or pulsator washing machines with heating functions, or washing equipment with a relatively small height that needs to be sealed, etc., all face the problem of water flow or foam overflowing or splashing during the washing process. Therefore, such washing equipment will adopt a sealing structure during design to make the entire washing space in a sealed state to solve the problem of water flow or foam overflow. However, after setting the washing space to be sealed, when water is inlet or drained, the pressure in the internal sealed space will increase, making it difficult to drain or inlet water. Therefore, there is a need for a solution that can both solve the problem of water flow or foam overflow and allow air to freely enter and exit.

[0003] Patent CN112376214A discloses a washing machine outer tub, including: a tub body, an exhaust hole is opened at the top of the tub body; an anti-foaming component, the anti-foaming component is arranged on the tub body; the anti-foaming component has an exhaust passage, the inlet end of the exhaust passage is communicated with the exhaust hole, and the outlet end is communicated with the outside; a baffle, the baffle is arranged in the inner cavity of the exhaust passage for bursting the foam. Based on the design structure that the exhaust hole is at the top of the washing machine outer tub in the assembled state of the washing machine outer tub, when washing water is injected into the inner tub assembled in the inner cavity of the washing machine outer tub, the highest water surface of the washing water will also be at a relatively far distance from the exhaust hole, which can make the foam generated by the washing water also be at a relatively far distance from the exhaust hole, reducing or avoiding the foam generated by the washing water from discharging along the exhaust hole from the source and reducing or avoiding the occurrence of foam overflow and water overflow problems.

[0004] In the above patent, it is necessary to burst the foam through a baffle, and the structure of the baffle is complicated, which will not only increase the manufacturing difficulty and cost, but also easily form sanitary dead corners between a large number of baffles and the side wall of the exhaust passage. The liquid generated after the foam bursts is likely to remain in these sanitary dead corners, eventually generating peculiar smells and mildew.

A lid assembly 100 of a washing device includes: a lid 10 and a ventilation structure 20. The lid 10 is provided on the upper side of the washing tub. The ventilation structure 20 is provided on the lid 10 and is used to connect the gas inside the washing tub with the outside. By providing the ventilation structure 20, the connection between the inside of the washing tub and the outside gas can be realized, avoiding the air pressure difference inside and outside the washing tub, which is beneficial to the smoothness of water inlet and drainage.

[0047] Specifically, the ventilation structure 20 has a ventilation cavity 21, a plurality of upper ventilation holes 221 opened on the cavity top 22 of the ventilation cavity 21, a plurality of lower ventilation holes 233 opened at the bottom of the ventilation cavity 21, and a ventilation block 24 provided between the upper ventilation holes 221 and the lower ventilation holes 233. The upper ventilation holes 221 and the lower ventilation holes 233 are arranged opposite to each other up and down. The structure of the ventilation structure 20 is simple. The upper ventilation holes 221, the lower ventilation holes 233, and the ventilation block 24 reduce the residue of foam or water. By providing the ventilation block, the passage of gas can be realized, and it has the function of absorbing water, reducing the overflow of water flow and foam. By providing a limiting plate, firstly, the limiting plate presses on the ventilation block, which is beneficial to the stability of the ventilation block after installation; secondly, after the ventilation block absorbs water, its ventilation function will be weakened or lost. By providing the limiting plate, the upper ventilation holes are spaced from the ventilation block, so that gas can pass through the ventilation structure without passing through the ventilation block.

[0048] A plurality of limiting plates 222 extending downward are provided on the cavity top. The limiting plates 222 are used to abut against the top of the ventilation block 24 to realize the upward limit of the ventilation block 24. By providing the ventilation block 24, the passage of gas can be realized, and it has the function of absorbing water, reducing the overflow of water flow and foam. By providing the limiting plates 222, firstly, the limiting plates 22 press on the ventilation block 24, which is beneficial to the stability of the ventilation block 24 after installation; secondly, after the ventilation block 24 absorbs water, its ventilation function will be weakened or lost. By providing the limiting plates 22, the upper ventilation holes 221 are spaced from the ventilation block 24, so that gas can pass through the ventilation structure without passing through the ventilation block.

[0049] In some embodiments of the present application, the ventilation block 24 is made of a porous, water-absorbing and elastic material, which can allow gas to pass through, and can play a filtering role; and can block the impact of water flow outward, and has the function of absorbing water, further avoiding the overflow of water flow and foam.

The blocking columns 223 block the side surface of the ventilation block 24. An avoidance notch 2311 for avoiding the blocking columns 223 is provided on the surrounding plate 231. By providing the blocking columns 223, they are used to abut against the side surface of the ventilation block 24, increasing the stability of the fixation of the ventilation block 24, and used to define the positional relationship between the top 22 of the cavity and the ventilation block 24.

The upper opening 111 is adjacently arranged with the installation opening 224, and a ventilation lid 225 is arranged to incline upward in a direction away from the upper opening 111. After the foam or water flow overflows the upper ventilation hole 221, the foam or water flow will flow into the upper opening 111 along the inclined surface at the upper end of the ventilation lid 225, avoiding the water flow from flowing out of the upper edge of the installation opening 224.

[0055] In some embodiments of the present application, an installation edge 112 that extends downward and bends inward is provided along the edge of the upper opening 111. The installation edge 112 is arranged to match the upper lid 12. A downward bent edge 2251 is provided at one end of the ventilation lid 225 close to the upper opening 111, and the bent edge 2251 is adjacently arranged with the installation edge 112.
