In some embodiments, the surface of the clamping portion 21 contacting the clamping groove 11 and the surface of the clamping groove 11 contacting the clamping portion 21 may each be provided with the anti-slip pattern 30. By providing the anti-slip patterns 30 on both the surface of the clamping portion 21 contacting the clamping groove 11 and the surface of the clamping groove 11 contacting the clamping portion 21, the sliding resistance between the clamping portion 21 and the clamping groove 11 can be increased, and the connection stability of the clamping portion 21 and the clamping groove 11 can be further improved, so that the clamping portion 21 and the clamping groove 11 can be prevented from being accidentally separated due to vibration during the operation of the clothes treating device.

In some embodiments, the anti-skid patterns 30 disposed on the surface of the clamping portion 21 contacting the clamping groove 11 may be matched with the anti-skid patterns 30 disposed on the surface of the clamping portion 21 contacting the clamping portion 11, and exemplary, the anti-skid patterns 30 disposed on the surface of the clamping portion 21 contacting the clamping portion 11 may be a convex structure, and the anti-skid patterns 30 disposed on the surface of the clamping portion 11 contacting the clamping portion 21 may be a concave structure matched with the convex structure. The anti-slip patterns 30 arranged on the surface of the clamping part 21, which is in contact with the clamping groove 11, can be matched with the anti-slip patterns 30 arranged on the surface of the clamping groove 11, which is in contact with the clamping part 21, so that the sliding resistance between the clamping part 21 and the clamping groove 11 can be further increased, the connection stability of the clamping part 21 and the clamping groove 11 is further improved, and the clamping part 21 and the clamping groove 11 are prevented from being accidentally separated due to vibration during the operation of the clothes treatment device.

In some embodiments, the anti-skid pattern 30 is one or more combinations of a zigzag pattern, a wavy pattern, a lug pattern, a longitudinal pattern, or a hybrid pattern. For example, the corresponding lug pattern may be set according to the relative sliding direction between the engaging portion 21 and the engaging groove 11, so that the anti-skid pattern 30 may exert a more excellent effect.

In some embodiments, as shown in fig. 1 and 2, the clamping portion 21 may have an extension portion 23, and the extension portion 23 may extend in any direction, thereby increasing the surface area of the clamping portion 21, and, as shown in fig. 1 and 2, for example, the extension portion 23 may extend in the length direction of the first portion 10 or the length direction of the second portion 20, thereby avoiding increasing the thickness of the clamping structure of the first portion 10 and the second portion 20.

As shown in fig. 1 and 2, the shape of the clamping groove 11 may be matched with the shape of the clamping portion 21 provided with the extension portion 23, and by providing the extension portion 23 on the clamping portion 21, the contact area between the clamping portion 21 and the clamping groove 11 may be increased, so that the liquid in the inner cylinder is prevented from leaking out from the gap between the clamping portion 21 and the clamping groove 11 when the laundry treatment apparatus is operated, and the waterproof effect between the clamping portion 21 and the clamping groove 11 is enhanced.

As shown in fig. 1 and 2, the extending portion 23 may make the clamping portion 21 have a T-shaped structure, so as to increase the contact area between the clamping portion 21 and the clamping groove 11, prevent the liquid in the inner cylinder from leaking out from the gap between the clamping portion 21 and the clamping groove 11 when the laundry treating apparatus is operated, and enhance the waterproof effect between the clamping portion 21 and the clamping groove 11.

In some embodiments, the clamping portion 21 is in interference connection with the clamping groove 11, so that acting force between the clamping portion 21 and the clamping groove 11 is increased, and a gap between the clamping portion 21 and the clamping groove 11 is reduced, which can strengthen a waterproof effect between the clamping portion 21 and the clamping groove 11 and prevent liquid of the inner cylinder from leaking out from the gap between the clamping portion 21 and the clamping groove 11 when the laundry treatment device is operated.

In some embodiments, as shown in fig. 1, the first portion 10 may include a first end 12 remote from the clamping groove 11 and the second portion 20 may include a second end 22 remote from the clamping portion 21.

The ratio of the distance from the first end 12 to the clamping groove 11 to the distance from the first end 12 to the second end 22 can be 0.08-0.32 by adjusting the position of the clamping structure on the door seal 3.

Controlling the ratio of the distance from the first end 12 to the clamping groove 11 to the distance from the first end 12 to the second end 22 in the above interval may make the first portion 10 which is not directly replaceable be 8% to 32% of the length of the dock seal 3, and the second portion 20 which is replaceable be 92% to 68% of the length of the dock seal 3. That is, controlling the ratio of the distance from the first end 12 to the clamping groove 11 to the distance from the first end 12 to the second end 22 in the above interval can enable as many parts of the dock seal 3 as possible to be detached and replaced more simply. The specific proportional setting can be set according to the size of the portion of the dock seal 3 that is in contact with the inner barrel space and the size of the portion that is at risk of mold formation and fouling. For example, the ratio of the distance from the first end 12 to the clamping groove 11 to the distance from the first end 12 to the second end 22 may be 0.1, that is, the non-replaceable first portion 10 accounts for 10% of the length of the dock seal 3, and the replaceable second portion 20 accounts for 90% of the length of the dock seal 3, so that the second portion 20 in contact with the humid environment of the inner cylinder may be more thoroughly replaced, thereby preventing the occurrence of the situation that the mildewed portion of the dock seal 3 cannot be replaced.

Fig. 3 is a schematic structural view of a seal ring of a door seal according to an exemplary embodiment.

In some embodiments, as shown in fig. 3, the laundry treating apparatus may include: sealing ring 4 and fixing portion 40

The sealing ring 4 may be provided at the second end 22 of the second portion 20. The sealing ring 4 may be a portion of the second portion 20 exposed to the opening and the sealing ring 4 seals the gap between the opening and the door. The sealing ring 4 can be matched with the shapes of the opening and the door, so that the sealing ring 4 can seal the gap between the opening and the door and prevent the content in the inner cylinder from flowing out of the gap between the opening and the door.

Because the dock seal 3 is made of elastic materials and has large dead weight, under the condition of fewer supporting points, the dock seal 3 is easy to bend and deform under the action of self gravity, and tension is generated at two ends of the dock seal 3, and the tension can influence the connection effect between the second end 22 of the dock seal 3 and the front plate 2. In order to enable the door seal 3 to be more stably installed in the laundry treating apparatus, as shown in fig. 3, the sealing ring 4 may be provided with a fixing portion 40, and the fixing portion 40 may fixedly connect the sealing ring 4 to the front plate 2. The sealing ring 4 is fixedly connected to the front plate 2 through the fixing portion 40, so that the connection effect between the second end 22 of the door seal 3 and the front plate 2 is firmer and more stable, the influence of the dead weight of the door seal 3 on the connection effect of the door seal 3 is weakened, and the door seal 3 can be more stably arranged in the clothes treatment device.

In some embodiments, since the dead weight of the dock seal 3 is large and the seal ring 4 is exposed to the front plate, the size of the fixing portion 40 that can be provided is limited for the size design of the whole laundry treating apparatus, and thus the fixing strength of the fixing portion 40 is limited. The door seal 3 can obtain a sufficient fixing effect, and the number of the fixing portions 40 can be plural, and as an example, as shown in fig. 3, the number of the fixing portions 40 can be 4.

However, the present disclosure is not limited thereto, and the fixing portions 40 may be provided in other numbers, and the specific number may be determined according to the fixing strength of the fixing portions 40 and the fixing requirement of the dock seal 3.

In some embodiments, the securing portion 40 may be a clasp. When the second portion 20 needs to be detached, the fastening structure can be used for simply detaching the sealing ring 4, and when the second portion 20 needs to be installed, the fastening structure can be used for simply installing and connecting the sealing ring 4. And the snap-on construction can be well adapted to the dock seal 3 as an elastic material.

In some embodiments, the fixing portion 40 may be an interference connection, and the front plate 2 is provided with an interference connection hole corresponding to the fixing portion 40. When the second portion 20 needs to be disassembled, the sealing ring 4 can be disassembled and separated by pulling out the interference connecting piece from the interference connecting hole, and when the second portion 20 needs to be installed, the sealing ring 4 can be installed and connected by inserting the interference connecting piece into the interference connecting hole.

In some embodiments, the fixing portions 40 may be uniformly disposed around the sealing ring 4, and as illustrated in fig. 3, for example, the fixing portions 40 may be 4, the sealing ring 4 may be circular, and the 4 fixing portions 40 may be disposed on the sealing ring 4 at quarter-circle intervals. Can make fixed portion 40 even to the fixed effect of sealing ring 4 even through locating sealing ring 4 with fixed portion 40, sealing ring 4 atress is uneven, takes place permanent deformation under the effect of self gravity, and then leads to taking place irreversible deformation, leads to sealing ring 4 damage.

According to the embodiment of the disclosure, the door seal 3 of the clothes treatment device is configured into the first part 10 and the second part 20 which are detachably connected, and only the second part 20 can be replaced when the clothes treatment device is replaced and maintained, so that after the second part 20 is mildewed or severely worn, the door seal 3 can be repaired through simple replacement of the second part 20, and the service life of the washing machine is prolonged.
