When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0064] In the present disclosure, unless otherwise stated, the orientation terms "first direction, second direction, and third direction" refer to three intersecting directions. Specifically, the first direction, second direction, and third direction can be perpendicular to each other in pairs, and specifically, reference can be made to Figure 1 as shown; the orientation terms such as "up, down, left, right, front, and back" refer to up, down, left, right, front, and back defined when the washing machine is in a normal use state; the terms such as "first and second" are only used to distinguish one element from another element, and do not have sequentiality and importance.

[0065] Referring to Figures 1 to 6 as shown, the present disclosure provides a drainage and ventilation structure 100. The drainage and ventilation structure 100 includes a housing 10. An independent and partitioned ventilation cavity 20 and a drainage cavity 30 are provided inside the housing 10.

The outer drain port 103 is communicated with the downstream ends of the plurality of drainage channels 301.

[0066] In the above technical solution, by providing a ventilation cavity 20 and a drainage cavity 30 in the housing 10, the gas entering from the air inlet 102 can be discharged through the external exhaust port 101 after entering the ventilation cavity 20. Water enters into a plurality of drainage channels 301 through a plurality of water inlets 104. Since the plurality of drainage channels 301 communicate with each other in the drainage cavity 30, the water can be discharged from the drainage cavity 30 through the external drainage port 103. Additionally, the ventilation cavity 20 and the drainage cavity 30 are independent and separated from each other. That is to say, the drainage and ventilation structure 100 of the present disclosure integrates the ventilation cavity 20 and the drainage cavity 30 in a single housing 10, which can not only drain water but also ventilate, with a compact structural design and high integration, effectively reducing the number of parts and costs.

However, the present disclosure does not limit the specific shape of the first drainage channel 3011. Additionally, the present disclosure does not limit the number of the drainage channels 301 and the water inlets 104 either.

When water enters the drainage cavity 30 from the first water inlet 1041, it first passes through the first channel segment 3013 and then flows to the second channel segment 3014, and then is discharged from the drainage cavity 30 through the external drain outlet 103. When water enters the drainage cavity 30 from the second water inlet 1042 and enters the second drain channel 3012, then the water at the downstream end of the second drain channel 3012 can converge with the water downstream of the second channel segment 3014, and then the water is discharged through the external drain outlet 103.

That is, the drainage and ventilation structure 100 integrates the ventilation cavity 20 and the drainage cavity 30 in a housing 10 and is arranged in the washing machine, which can not only drain the washing machine but also ventilate it. The structure design is compact and the integration degree is high, effectively reducing the number of parts and costs.

[0086] The washing machine further includes a large drum drain pipe (not shown), a small drum drain pipe (not shown), and a small drum exhaust pipe (not shown); the multiple washing drums include a large drum body (not shown) and a small drum body (not shown); one end of the small drum drain pipe communicates with the small drum drain port of the small drum body, and the other end communicates with the second water inlet 1042; one end of the large drum drain pipe communicates with the large drum drain port of the large drum body, and the other end communicates with the first water inlet 1041; one end of the small drum exhaust pipe communicates with the exhaust port of the small drum body, and the other end communicates with the air inlet 102; wherein, the first direction A is configured as the up-down direction, the second direction B is configured as the left-right direction, and the third direction C is configured as the front-back direction. That is, the drainage of both the large drum body and the small drum body is discharged into the drainage cavity 30, and the exhaust of the small drum body is discharged into the ventilation cavity 20, realizing the drainage of the large drum body and the small drum body, as well as the exhaust of the small drum body, which is beneficial to the simplification of the structure and the drainage and exhaust do not interfere with each other.

[0087] In other embodiments, the washing machine further includes a drainage pump and a drainage valve; wherein, both the small drum body and the drainage and ventilation structure 100 are arranged above the large drum body; the small drum drain port is located above the second water inlet 1042, and the drainage valve is arranged on the small drum drain pipe; the large drum drain port is located below the first water inlet 1041, and the drainage pump is arranged on the large drum drain pipe.

[0088] In this embodiment, since the large drum drain port is located below the first water inlet 1041, it is convenient to realize the upward transportation of the drainage by setting the drainage pump. The small drum drain port is located above the second water inlet 1042, so the gravity can be utilized to transport the water into the drainage cavity 30. By setting the drainage valve, it is convenient to control the opening and closing of the drainage pipeline.

[0089] Optionally, the second end of the first partition plate 1071 is configured as the upper end of the first partition plate 1071; wherein, the second end of the first partition plate 1071 is located above the air inlet 102, and the second end of the first partition plate 1071 is located above the highest washing water level and the abnormal alarm water level of the small drum body.

[0090] First, due to the pumping pressure of the drainage pump, the drainage of the small cylinder can be prevented from flowing back into the large cylinder. When the external drainage pipe 60 is blocked, the drainage of the small cylinder is discharged into the second drainage channel 3012. When the second drainage channel 3012 is filled with drainage and then flows back into the second channel section 3014, since the second end of the first partition plate 1071 is above the highest washing water level and the abnormal alarm water level of the small cylinder, when the water in the small cylinder reaches the highest washing water level and the abnormal alarm water level, the small cylinder will not continue to intake water, that is, the drainage will not flow back to the first channel section 3013 through the second channel section 3014, that is, it will not flow back into the large cylinder.

[0091] Other embodiments of the present disclosure will be readily apparent to those skilled in the art upon considering the specification and practicing the present disclosure. This application is intended to cover any variations, uses, or adaptations of the present disclosure, which follow the general principles of the present disclosure and include known common knowledge or conventional technical means in the technical field not disclosed by the present disclosure.
