In the following description, details are set forth for purposes of explanation. It should be understood that those of ordinary skill in the art can recognize that the present application can be implemented without the use of these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but rather to be in line with the broadest scope consistent with the principles and features disclosed in the present application.

[0032] An embodiment of the present application provides a water inlet structure and a laundry treatment device. The laundry treatment device can be a washing machine or other devices, etc. The washing machine has a steam washing or drying function.

[0033] On the one hand, an embodiment of the present application provides a water inlet structure, including a water inlet pipe 1 and a sealing assembly 2; the water inlet pipe 1 is connected to the water injection hole 31 of the washing barrel 3 of the clothing processing equipment; the sealing assembly 2 includes a mounting portion 21 and a movable portion 23, the mounting portion 21 is arranged at the water injection hole 31, the mounting portion 21 has a water outlet 22, the water outlet 22 is used to connect the water injection hole 31 and the outlet of the water inlet pipe 1, and the movable portion 23 can be movably connected to a side of the mounting portion 21 away from the water inlet pipe 1, so as to swing away from the mounting portion 21 to open the water outlet 22, or swing against an end face of the mounting portion 21 away from the water inlet pipe 1 to seal and cover the water outlet 22.

[0034] In the embodiment of the present application, the sealing assembly 2 is installed at the water injection hole 31 of the washing bucket 3. The sealing assembly 2 includes two parts: a mounting portion 21 and a movable portion 23. The movable portion 23 is arranged on one side of the mounting portion 21 and can swing relative to the mounting portion 21. The mounting portion 21 has a water inlet 22 connected to the water injection hole 31. The water injection hole 31 is also connected to a water inlet pipe 1. The water inlet pipe 1 is located on a side away from the washing bucket 3. The water inlet 22 is connected to the water inlet pipe 1. When water needs to be supplied to the washing bucket 3, water flows out from the water inlet pipe 1 to the mounting portion 21. At this time, the movable portion 23 will swing to the side away from the water inlet pipe 1 due to the impact of water to open the water inlet 22, thereby allowing water to flow into the washing bucket 3. When water does not need to be supplied, the movable portion 23 will be attached to one side of the mounting portion 21. The end surface is formed by sealing the water outlet 22, thereby sealing and covering the water outlet 22. When there is a lot of hot water vapor in the washing tub 3, the water vapor will escape outward from the water injection hole 31. When the water vapor flows to the water outlet 22, since the water outlet 22 is sealed and covered by the movable part 23, the water vapor can be prevented from flowing outward, and the water vapor can further increase the pressure on the movable part 23, so that the movable part 23 is further pressed against the mounting part 21. This arrangement can prevent the water vapor in the washing tub 3 from flowing outward from the water injection hole 31 as much as possible, thereby preventing the water vapor from flowing to the detergent box 4 and even the control panel, so as to avoid the condensation of water vapor on the surface of the detergent box 4 and the surface of the control panel. In this way, it can be ensured that there will not be too much condensed water dripping on the ground after the user uses the washing machine, thereby improving the user experience.

[0035] Furthermore, the area of ​​the movable portion 23 is larger than the area of ​​the water outlet 22 , thereby ensuring that the movable portion 23 can completely cover the water outlet 22 , thereby ensuring the sealing effect of the water outlet 22 .

[0036] In some embodiments, the mounting portion 21 is annular, and a limiting step 32 is provided in the water injection hole 31. One side of the mounting portion 21 abuts against the side of the limiting step 32 close to the water inlet pipe 1. The limiting step 32 is used to limit the axial movement of the mounting portion 21 in the water injection hole 31.

[0037] Specifically, the limiting step 32 protrudes from the inner wall of the water injection hole 31, and the mounting portion 21 abuts against one side of the limiting step 32 close to the water inlet pipe 1, that is, the mounting portion 21 will not move inward along the circumferential direction of the water injection hole 31 under the impact of water flow. Such a setting limits the mounting portion 21 through the limiting step 32, so as to increase the mounting stability of the mounting portion 21 and prevent the sealing assembly 2 from being washed into the water injection hole 31 during use. In some other embodiments, the water injection hole 31 is provided with internal threads, and the circumferential wall of the mounting portion 21 is provided with external threads, and the mounting portion 21 is screwed into the water injection hole 31.

[0038] In some embodiments, the limiting step 32 extends circumferentially along the water injection hole 31 to form a ring.

[0039] Specifically, the limiting step 32 is adapted to the mounting portion 21 to form a ring, and the width of the limiting step 32 is less than or equal to the width of the mounting portion 21. Here, the width refers to the distance from the inner edge to the outer edge of the ring structure. Such a setting can increase the contact area between the limiting step 32 and the mounting portion 21, so that the limiting step 32 can limit more parts of the mounting portion 21, thereby increasing the limiting effect on the mounting portion 21 and further improving the mounting stability of the mounting portion 21. In some other embodiments, there are multiple limiting steps 32, and multiple limiting steps 32 are all used to abut against the mounting portion 21, and multiple limiting steps 32 are sequentially and spaced apart along the circumferential direction of the water injection hole 31. Further, multiple water injection holes 31 are evenly spaced along the circumferential direction of the water injection hole 31.

[0040] In some embodiments, an annular protrusion 11 is provided in the water inlet pipe 1, the end of the water inlet pipe 1 is sleeved on the outer peripheral wall of the water injection hole 31, and the annular protrusion 11 is used to press the mounting portion 21 against the limiting step 32.

[0041] Specifically, a water injection pipe 34 protrudes from the outer wall of the washing tub 3. The water injection pipe 34 is cylindrical, the water injection hole 31 penetrates through the water injection pipe 34, the water inlet pipe 1 is sleeved on the water injection pipe 34, and an annular protrusion 11 protrudes from the inner wall of the water inlet pipe 1. The shape of the annular protrusion 11 is adapted to the shape of the mounting portion 21. One side of the mounting portion 21 first abuts against the limiting protrusion, and then the water inlet pipe 1 is sleeved on the water injection hole 31. At this time, the annular protrusion 11 in the water inlet pipe 1 can press the mounting portion 21 against the limiting protrusion from the other side of the mounting portion 21. Such a setting can further increase the mounting stability of the sealing assembly 2. After the assembly is completed, the mounting portion 21 cannot move axially. In some other embodiments, the water inlet pipe 1 is hermetically inserted into the water injection hole 31, and one end face of the water inlet pipe 1 facing the mounting portion 21 is used to abut against one side of the mounting portion 21, and the water inlet pipe 1 can press the mounting portion 21 against the limiting protrusion.

[0042] In some embodiments, the water inlet structure includes a sealing ring 25, and the sealing ring 25 is clamped between the inner wall of the water inlet pipe 1 and the outer peripheral wall of the water injection hole 31.

[0043] Specifically, a sealing ring 25 is also sleeved on the water injection pipe 34, and then the water inlet pipe 1 is sleeved on the water injection pipe 34. The sealing ring 25 can seal the gap between the water inlet pipe 1 and the water injection pipe 34. At the same time, due to the large elasticity of the sealing ring 25, the friction force with the inner wall of the water inlet pipe 1 can be increased. Such a setting can improve the installation stability of the water inlet pipe 1 and also achieve the sealing between the water inlet pipe 1 and the water injection hole 31. In some other embodiments, the water inlet pipe 1 is inserted into the water injection hole 31, and the water inlet structure includes a sealing ring 25, and the sealing ring 25 is clamped between the outer peripheral wall of the water inlet pipe 1 and the inner peripheral wall of the water injection hole 31.

[0044] In some embodiments, a plurality of positioning convex portions 33 are provided on the inner wall of the water injection hole 31. The positioning convex portions 33 extend along the axial direction of the water injection hole 31 to the limiting step 32. A positioning surface 21a is provided on the outer peripheral edge of the mounting portion 21. The mounting portion 21 is embedded between the plurality of positioning convex portions 33 and abuts against the limiting step 32, and the positioning surface 21a abuts against the positioning convex portions 33.

[0045] Specifically, the plurality of positioning convex portions 33 are evenly spaced along the circumferential direction of the water injection hole 31. In this embodiment, the positioning convex portions 33 are provided at the water injection hole 31 and extend from the water injection hole 31 to the limiting step 32 all the way. In this way, the opening of the water injection hole 31 can be changed into a polygonal opening, and the outer shape of the mounting portion 21 is adapted to the polygonal opening. The plane on the outer peripheral wall of the mounting portion 21 is the positioning surface 21a, and the positioning surface 21a is arranged in one-to-one correspondence with the positioning convex portions 33. Under the limitation of the plurality of positioning convex portions 33, the mounting portion 21 is embedded in the water injection hole 31. Such a setting can limit the rotation of the sealing assembly 2, thereby increasing the installation stability of the sealing assembly 2 installed here and preventing the sealing assembly 2 from rotating and affecting the sealing performance. In some other embodiments, an inlaid convex portion is provided on one side of the mounting portion 21 facing the limiting step 32. The inlaid convex portion is square, and a square opening is provided on the limiting step 32. The inlaid convex portion is inlaid in the square opening to position the mounting portion 21 in the water injection hole 31.

[0046] In some embodiments, the sealing assembly 2 further includes a flexible connection portion 24. One end of the flexible connection portion 24 is connected to the end face of the mounting portion 21 away from the water inlet pipe 1, and the other end is connected to the edge of the movable portion 23. The flexible connection portion 24 is arranged to avoid the limiting step 32.

[0047] Specifically, a flexible connection part 24 is provided at the connection between the installation part 21 and the movable part 23. The flexible connection part 24 is made of soft rubber material and can undergo a certain deformation. Moreover, the flexible connection part 24 is in the shape of a thin sheet. The upper end of the flexible connection part 24 is connected to the upper side of the installation part 21 and is radially spaced from the limiting step 32. The lower end of the flexible connection part 24 is connected to the upper edge of the movable part 23. With such a setting, when the movable part 23 swings relative to the installation part 21, the flexible connection part 24 will not interfere with other structures during the deformation process. In some other embodiments, one end of the flexible connection part 24 is connected to the inner peripheral wall of the installation part 21, and the other end is connected to the outer peripheral wall of the movable part 23.

[0048] In some embodiments, the installation part 21, the flexible connection part 24, and the movable part 23 are integrally formed.

[0049] Specifically, the installation part 21, the flexible connection part 24, and the movable part 23 are integrally injection-molded. Such a setting can enhance the connection stability among the three, making the overall strength of the sealing component 2 relatively high, ensuring that the sealing component 2 is not easily broken during use, improving the service life, and the cost of integral molding is relatively low, which can save costs. In some other embodiments, the installation part 21, the flexible connection part 24, and the movable part 23 are adhesively bonded in sequence.

[0050] In some embodiments, at least one of the installation part 21 and the movable part 23 is made of an elastic material.

[0051] Specifically, in this embodiment, the movable part 23 is made of an elastic material and the installation part 21 is a rigid part. When hot water vapor surges out from the washing tub 3 through the water injection hole 31, the movable part 23 can undergo a certain deformation, so that the movable part 23 can be in interference fit with the water passing port 22, that is, the gap between the water passing port 22 and the movable part 23 is sealed, so the water vapor cannot escape outward from the water passing port 22. Such a setting can achieve the one-way conduction of the water passing port 22, only allowing water to enter the washing tub 3 from the outside and preventing the water vapor from moving outward.

[0052] On the other hand, the embodiment of the present application provides a laundry treatment device, including the water inlet structure as described above and the washing tub 3. A water injection pipe 34 protrudes from the washing tub 3, and a water injection hole 31 is provided through the water injection pipe 34. The water inlet pipe 1 is detachably sleeved on the water injection pipe 34.

[0053] Specifically, the laundry treatment device is an integrated washing and drying washing machine. This washing machine has a drying function and a steam washing function. During use, hot water vapor will be generated. The water inlet structure is connected to the water injection pipe 34 of the washing tub, which can prevent the backflow of the water vapor, so as to ensure that there will be no condensed water on the surface of the washing machine and the condensed water will not drip onto the ground.

[0054] The above has introduced in detail the water inlet structure and the laundry treatment equipment provided by the embodiments of the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those skilled in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
