At the same time, the structure integrates multiple functions, is easy to install and use, and improves the user experience.

[0060] Regarding the defoaming structure, in this embodiment, the defoaming structure preferably includes a protrusion formed on the inner wall of the second chamber 43, and the protrusion has a free end extending toward the hollow interior of the second chamber 43. In order to improve the defoaming efficiency, it is further preferred that a plurality of protrusions are provided and staggered along the direction of the gas flow toward the exhaust port 432.

[0061] In order to improve the defoaming efficiency, this embodiment not only optimizes the defoaming structure, but also designs the structure of the second chamber. Preferably, the second chamber 43 includes an exhaust chamber 433 and a defoaming chamber 434, the air inlet 431 is connected to the exhaust chamber 433, the exhaust port 432 is connected to the defoaming chamber 434, and a connecting hole 435 is formed between the exhaust chamber 433 and the defoaming chamber 434.

[0062] like Figure 2-4As shown, in order to give full play to the exhaust, defoaming and water intake functions of the multifunctional connector, in this embodiment, regarding the structure of the multifunctional connector, preferably, the first chamber 42 and the second chamber 43 are formed up and down; the exhaust chamber 433 and the defoaming chamber 434 of the second chamber 43 are formed up and down; the defoaming chamber 434 is located above the exhaust chamber 433, and the exhaust chamber 433 is located above the first chamber 42; the protrusions used for defoaming include a first protrusion 436 and a second protrusion 437, wherein: the first protrusion 436 is formed at the connecting hole 435, covering part of the connecting hole 435; the second protrusion 437 is formed on the inner wall of the defoaming chamber 434 of the second chamber 43; and the first protrusion 436 and the second protrusion 437 are alternately arranged. When the foam enters the second chamber, it will first pass through the exhaust chamber, and the foam will overflow onto the connecting hole. The first protrusion on the connecting hole will first cause a large amount of foam to burst. At the same time, the foam will continue to rise into the defoaming space under the blocking effect of the first protrusion, and will be broken by the second protrusion. The broken foam will become liquid and can be discharged from the air inlet along the inner wall of the second chamber. This structure can prevent foam overflow and avoid electrical safety hazards.

Further preferably, a dense hole structure 45 is provided on the inner cross section of the exhaust hose 44 to further reduce foam overflow.

Further preferably, the cross-sections of the liquid inlet 421 and the liquid outlet 422 are circular, and the circular cross-sections of the liquid inlet 421 and the circular cross-sections of the liquid outlet 422 are not coaxial. Further preferably, the highest point of the circular cross-section of the liquid inlet 421 is tangent to the lowest point of the circular cross-section of the liquid outlet 422. The water flow of the joint can be effectively divided, and the water flow can be effectively dispersed along the pipe wall, greatly reducing the generation of noise.

[0066] The multifunctional connector provided in this embodiment can realize the three functions of water intake, foam elimination and exhaust, simplify the pipeline layout, reduce the space occupied by the pipeline system and reduce the production and assembly costs; at the same time, the connector can effectively eliminate foam and make the foam flow out from the air inlet after it turns into liquid, so as to prevent foam overflow and avoid electrical safety hazards; at the same time, the variable diameter design of the connector can reduce the noise generated when water enters and improve the user experience; the multifunctional connector has a compact structure, high stability, comprehensive functions and is easy to install.

[0075] The washing machine provided by this embodiment, when the air pressure in the drum of the washing machine is too high, the gas can be discharged from the exhaust hole to maintain the air pressure balance in the drum, and avoid abnormal water inlet and outlet caused by excessive air pressure in the barrel. At the same time, when high foaming occurs in the drum of the washing machine, the foam will overflow to the connecting hole, and the first protrusion and the second protrusion can effectively break the foam. After the foam becomes liquid, it can also flow back to the inner drum of the washing machine through the adapter. This structure can prevent the foam from overflowing and avoid electrical safety hazards. The joint adopts a variable diameter design, which can reduce the impact of water flow on the inner drum during water inlet, thereby reducing the noise of washing in the washing machine and improving the user experience.
