[0028] Next, the embodiments of this specification are described in detail.

[0029] At present, some washing machines have the functions of washing and drying clothes at the same time. When the water level in the washing drum is too high, there is a risk of water entering the drying component. The water flow will enter the drying component through the drying channel and cause damage to the working electrical appliances. Therefore, the present disclosure provides a washing machine to solve the related technical problems.

[0030] like Figure 1 As shown, the present disclosure provides a washing machine, including a washing drum 10, a detergent box 20, a drying assembly 30, a water inlet pipe 40 and a water supply pipe 50. The two ends of the water inlet pipe 40 are respectively provided with a water inlet 401 and a water outlet 402. The water inlet 401 is installed to the detergent box 20, and the water outlet 402 is installed to the washing drum 10. The drying assembly 30 includes a main body 31 and a working electrical appliance 32. A drying channel 310 is provided in the main body 31, and the working electrical appliance 32 is arranged in the drying channel 310. The drying channel 310 is connected to the washing space 100 in the washing drum 10. The water inlet pipe 40 is provided with a drain port 400.

[0031] By providing the drain port 400 on the water inlet pipe 40, when the water level in the washing drum 10 is too high, the water will be discharged from the drain port 400 and enter the washing machine body, so that the water level in the washing drum 10 is effectively controlled. At the same time, since the water inlet pipe 40 is a component of the washing machine, the water inlet pipe 40 is used to realize the drain function, eliminating the need for an additional drain structure, and the structure is simple, easy to use and install. Moreover, in different types, the washing machine only needs to change the structure of the water inlet pipe 40, which has good compatibility.

[0032] In the height direction of the washing machine, any working appliance 32 is located above the drain port 400. Specifically, in the height direction, the lowest point of the working appliance 32 is located above the lowest point of the drain port 400. In one embodiment, the drain port 400 and the working appliance 32 are both arranged horizontally, and the plane where the bottom of the working appliance 32 is located is located above the plane where the drain port 400 is located. This arrangement can prevent water from entering the working appliance 32 from the drying channel 310, avoid the working appliance 32 from being damaged by water, increase the safety performance of the washing machine, and improve the user experience.

[0033] The number of the working electrical appliances 32 is not limited, and may include motors, NTCs (Negative Temperature Coefficient, thermistors), etc. When there are multiple working electrical appliances 32 in the drying assembly 30 , the lowest working electrical appliance 32 is located above the drain port 400 .

[0034] The type of washing machine disclosed in the present invention is not limited, and it can be a drum washing machine or a pulsator washing machine. Figure 1 As shown, the washing machine is a drum washing machine. The washing drum 10 is horizontal and is installed in the middle of the washing machine. The washing drum 10 is rotated to beat the clothes to achieve the cleaning effect.

[0035] The detergent box 20 is installed above the washing drum 10, and the water inlet pipe 40 is installed between the washing drum 10 and the detergent box 20. The water supply pipe 50 can be connected to the detergent box 20 to transport the external water source into the detergent box 20. The detergent such as the laundry liquid and disinfectant in the detergent box 20 is flushed and enters the washing drum 10 with the water flow to wash the clothes.

[0036] In this embodiment, if Figure 1 As shown, the drying assembly 30 is installed above the washing drum 10. The main body 31 is fixed to the washing drum 10, and an opening is provided at the connection between the two to connect the washing space 100 and the drying channel 310. The drying assembly 30 generates hot air and blows the hot air into the washing space 100 through the drying channel 310 to dry the clothes.

[0037] In one embodiment, the height difference between the drain port 400 and any working electrical appliance 32 is greater than or equal to 60 mm. Specifically, in the height direction, the height difference between the lowest point of the drain port 400 and the lowest point of the working electrical appliance 32 is greater than or equal to 60 mm. Figure 1 In the illustrated embodiment, the drain port 400 and the working electrical appliance 32 are both arranged horizontally, and the height difference between the plane where the drain port 400 is located and the plane where the bottom of the working electrical appliance 32 is located is greater than or equal to 60 mm.

[0038] By increasing the height difference between the drain port 400 and the working electrical appliance 32, water splashing in the washing tub 10 is prevented from invading the working electrical appliance 32 through the drying channel 310, and the working electrical appliance 32 is further prevented from being invaded by water flow, thereby enhancing the safety performance of the washing machine.

[0039] The arrangement of the drain port 400 is not limited. Figure 2 As shown, the water inlet pipe 40 may include a main pipe 41 and a branch pipe 42 extending from the outer wall of the main pipe 41. The drain port 400 is arranged in the branch pipe 42, which can reduce the impact of the drain port 400 on the water inlet. During normal water inlet, a large amount of water will not leak out through the drain port 400.

[0040] In this embodiment, the extension direction of the branch pipe 42 can be toward one end of the water inlet 401 of the water inlet pipe 40, and the drain port 400 is provided at the end surface 422 of the branch pipe 42. This arrangement further reduces the influence of the overflow port 400 on the water inlet, and because the branch pipe 42 is toward one end of the water inlet 401, the water flow entering the branch pipe 42 will fall back and still enter the washing tub 10.

[0041] In this embodiment, the direction of the drain port 400 may be the same as that of the water inlet 401. The water inlet 401 and the drain port 400 may both be arranged upward. The water inlet direction is opposite to the discharge direction, and the impact during normal water inlet is unlikely to cause the water flow to reverse, further preventing the inlet water from leaking out through the drain port 400.

[0042] like Figure 2 As shown, the water inlet pipe 40 includes a water inlet section 411, a water outlet section 412, and a vibration reduction section 413 disposed between the water inlet section 411 and the water outlet section 412. In one embodiment, the extension direction of the vibration reduction section 413 is perpendicular to the extension direction of the water inlet section 411 or the water outlet section 412. The extension direction of the vibration reduction section 413 may also be perpendicular to the extension direction of both the water inlet section 411 and the water outlet section 412. This arrangement can increase the complexity of the internal flow channel of the water inlet pipe 40, and the water inlet pipe 40 can play a certain role in storing water, and can limit the water level in the washing drum 10.

[0043] like Figure 3 and Figure 4 As shown, the outer wall of the water inlet pipe 40 is provided with a communication port 403. The communication port 403 divides the outer wall of the water inlet pipe 40 into a first area 4101 and a second area 4102. The first area 4101 is close to the water inlet 401. The second area 4102 is close to the water outlet 402. The first area 4101 is located above the communication port 403, and the second area 4102 is located above the communication port 403.

[0044] In one embodiment, if Figure 3 As shown, the second area 4102 can protrude to form a branch pipe wall 421. The branch pipe wall 421 encloses the overflow space 420. The connecting port 403 connects the overflow space 420 with the internal space of the water inlet pipe 40. The connecting port 403 divides the outer wall of the water inlet pipe 40 into two parts, and the branch pipe wall 421 is formed by protruding from only one part, which has a simple structure and is easy to manufacture. It can also reduce the amount of material used and save costs. The branch pipe wall 421 can be in a semi-bowl shape, and the specific structural form is not limited.

[0045] In this embodiment, the first area 4101 may include a baffle area 4103, and the projection of the baffle area 4103 overlaps with the projection of the connecting port 403 in a direction perpendicular to the connecting port 403. By providing the baffle area 4103, the flow of the incoming water can be blocked to a certain extent, preventing the normal inflow of the water from entering the overflow space 420.

[0046] In this embodiment, the communication port 403 may be disposed on the end surface 422 of the branch pipe wall 421. The distance that the baffle area 4103 extends beyond the end surface 422 is greater than or equal to 5 mm. By increasing the distance that the baffle area 4103 extends beyond the end surface 422, the projected overlapping area of ​​the baffle area 4103 and the communication port 403 can be increased, so as to improve the blocking effect of the baffle area 4103 on normal water inflow.

[0047] like Figure 1 As shown, the water supply pipe 50 is connected to the washing space 100. The water supply pipe 50 can be assembled to the washing drum 10 and directly connected to the washing space 100. The water supply pipe 50 can also be assembled to the detergent box 20 and indirectly connected to the washing space 100. In one embodiment, the cross-sectional area of ​​the drain port 400 is larger than the cross-sectional area of ​​the flow channel in the water supply pipe 50. By increasing the cross-sectional area of ​​the drain port 400 to be larger than the cross-sectional area of ​​the flow channel in the water supply pipe 50, the maximum discharge rate of the drain port 400 is greater than the water supply rate.

[0048] In some usage scenarios, such as when the washing machine fails, the drain port 400 is already in a draining state, while the water supply pipe 50 is still supplying water to the washing space 100. At this time, since the maximum drain flow rate is greater than the water supply rate, the excess water transported into the washing space 100 by the water supply pipe 50 can be smoothly discharged from the drain port 400, preventing the water level from further rising.

[0049] The above is only a preferred embodiment of the present disclosure and does not limit the present disclosure in any form. Although the present disclosure has been disclosed as a preferred embodiment as above, it is not used to limit the present disclosure. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present disclosure. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present disclosure without departing from the content of the technical solution of the present disclosure are still within the scope of the technical solution of the present disclosure.
