The enclosure 13 is provided with an installation opening 14 for assembling the filter 20, and the installation opening 14 is communicated with the washing chamber of the washing tub. The installation opening 14 and the operation button may be disposed on the top surface of the enclosure 13 on opposite sides.

[0067] The filter 20 can filter the water entering the washing chamber to prevent the mud, rust and other large particles in the tap water from affecting the washing effect of the clothes, thereby ensuring the washing quality of the clothes in the washing machine 100.

[0068] In some embodiments of the present application, the filter 20 may include a main housing 21 and a filter assembly. The filter assembly may include a filter housing 22 and a filter element 23. The filter element 23 is used to filter the tap water entering the washing chamber.

[0069] In some examples, the main housing 21 may be provided with a water inlet 201, which can be used to access tap water. The main housing 21 may also be provided with a water outlet 202, which can be communicated with the washing chamber.

[0070] In some examples, the filter housing 22 is detachably connected to the main housing 21 , and the filter element 23 is disposed in the filter housing 22 to divide the internal space of the filter housing 22 into a pre-filter cavity 203 and a post-filter cavity 204 .

[0071] Among them, the water inlet 201 on the main shell 21 is connected with the pre-filtration cavity 203 through the interior of the main shell 21, and the water outlet 202 is connected with the post-filtration cavity 204 through the interior of the main shell 21, so that tap water enters the pre-filtration cavity 203 through the water inlet 201, can be filtered by the filter element 23, and the filtered tap water can enter the washing cavity through the post-filtration cavity 204 and the water outlet 202.

[0072] In some embodiments of the present application, the main housing 21 may include a main cylinder 211, which is a cylindrical structure as a whole and is vertically connected to the frame 13 of the box body 10. The main cylinder 211 is open at both ends and hollow inside, the top opening of the main cylinder 211 is a top opening, and the bottom opening of the main cylinder 211 is a bottom opening.

[0073] In some embodiments, the main housing 21 may further include a top joint 212, which is disposed at the top opening of the main cylinder 211. The top joint 212 may include a first joint portion 2121 and a second joint portion 2122 connected to each other, and the first joint portion 2121 and the second joint portion 2122 are both hollow cylindrical structures.

[0074] The interior of the first joint part 2121 is connected to the interior of the second joint part 2122, forming a water inlet 201 arranged at the top of the main cylinder 211. The top joint 212 can be connected to a water pipe, so that tap water enters the main cylinder 211 through the interior of the first joint part 2121 and the second joint part 2122.

[0075] In some examples, the diameter of the first joint portion 2121 is greater than the diameter of the second joint portion 2122, and a step-like structure is formed between the first joint portion 2121 and the second joint portion 2122. The first joint portion 2121 is connected to the top opening of the main cylinder 211, and the second joint portion 2122 is disposed at the end of the first joint portion 2121 away from the main cylinder 211.

[0076] This arrangement allows the tap water to first pass through the second joint part 2122 with a smaller diameter, and then enter the main cylinder 211 through the first joint part 2121 with a larger diameter. This allows the flow rate of the tap water to change transitionally, avoiding a large water flow impact on the main cylinder 211, and ensuring the stability of the overall structure of the filter 20.

[0077] In some embodiments, the main housing 21 may further include a bottom joint 213. The bottom joint 213 is disposed at the bottom opening of the main cylinder 211.

[0078] The interior of the third joint part 2131 is connected to the interior of the fourth joint part 2132, forming a water outlet 202 arranged at the bottom of the main cylinder 211. The bottom joint 213 is arranged at the installation opening 14 of the surrounding frame 13, and the interior of the bottom joint 213 is connected to the interior of the washing chamber, so that the liquid inside the main cylinder 211 can enter the washing chamber through the bottom joint 213.

[0079] In some examples, the diameter of the third joint portion 2131 is greater than the diameter of the fourth joint portion 2132, and a step-shaped structure is formed between the third joint portion 2131 and the fourth joint portion 2132. The third joint portion 2131 is communicated with the bottom opening of the main cylinder 211, and the fourth joint portion 2132 is disposed at the end of the third joint portion 2131 away from the main cylinder 211. The fourth joint portion 2132 is penetrated in the installation opening 14 of the surrounding frame 13.

[0080] This arrangement allows the liquid flowing out of the main cylinder 211 to first pass through the third joint part 2131 with a larger diameter, and then enter the washing chamber through the fourth joint part 2132 with a smaller diameter, so that the water flow can smoothly enter the washing chamber to ensure the washing effect of the clothes.

[0081] In other examples, the main housing 21 can omit the top joint 212 and the bottom joint 213, that is, the top opening of the main cylinder 211 is the water inlet 201, the bottom opening of the main cylinder 211 is the water outlet 202, and the bottom of the main cylinder 211 is inserted into the mounting opening 14 of the surrounding frame 13. The tap water and the washing chamber are connected through the main cylinder 211, so that the overall structure is simpler.

[0082] In some embodiments of the present application, the filter 20 may further include a connection sealing gasket 205. The connection sealing gasket 205 is ring-shaped and may be made of sealing materials such as silicone or rubber.

[0083] The connection sealing gasket 205 is arranged inside the third joint part 2131 and corresponds to the end surface of the fourth joint part 2132 to seal the peripheral side of the water outlet 202 of the filter 20 to ensure the sealing of the connection between the filter 20 and the box body 10.

The first main body 2401 is arranged above the second main body 2402, the first main body 2401 is arranged close to the water inlet 201, and the second main body 2402 is arranged close to the water outlet 202.

[0092] The internal space of the main shell 21 corresponding to the area above the first main body 2401 constitutes a water inlet chamber 206 , and the internal space of the main shell 21 corresponding to the area below the second main body 2402 constitutes a water outlet chamber 207 .

[0093] In other examples, the first main body 2401 and the second main body 2402 can be configured as an integrated structure with a certain thickness. The integrated structure is arranged inside the main shell 21 and can separate the internal space of the main shell 21 into independent water inlet chamber 206 and water outlet chamber 207.

[0094] In some embodiments of the present application, the stopper 24 may further include a transition portion 242. The transition portion 242 can connect the two main bodies, so that the stopper 24 is an integral structure. The transition portion 242 is arranged at the end of the extension portion 2412 in the main body away from the main body portion 2411, and the transition portion 242 can also provide a mounting position for the filter element 23, so that the filter element 23 can be connected to the stopper 24.

[0095] The transition portion 242 is connected to the ends of the two main body portions, the top end of the transition portion 242 is connected to the end of the first main body portion 2401 , and the bottom end of the transition portion 242 is connected to the end of the second main body portion 2402 .

[0096] In other examples, the stopper 24 may include only two main parts, and the transition part 242 may be omitted, so that the internal space of the main shell 21 can be separated into independent water inlet chamber 206 and water outlet chamber 207 only by the main parts.
