[0029] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described and illustrated herein are intended to be illustrative only and are not intended to limit the present disclosure.

[0030] In the present disclosure, it is understood that, in the present disclosure, the orientation words such as "upper", "lower", etc. used to indicate the orientation or position relationship are defined based on the drawing direction shown in the corresponding drawings, which is only for the convenience of describing the present disclosure and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, and a particular orientation configuration and operation, therefore it cannot be understood as a limitation on the present disclosure, and the terms "inner, outer" can refer to the inner and outer of the corresponding structure profile. For example, the "height direction" of the washing machine 100 can refer to the height direction shown in the figure, which can be the same as the vertical direction, in addition, it should be noted that the terms "first", "second" and the like are used to distinguish one element from another element, and do not have sequential and important meanings. In addition, in the description with reference to the drawings, the same reference signs in different drawings represent the same elements. Figure 1

[0031] In the description of the present disclosure, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected", "connected", "mounted" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0032] Research shows that in the related art, since the thickness of each position of the washing machine door seal is consistent, it cannot meet the different sealing requirements between the washing machine door body and the washing machine door seal, resulting in that the sealing effect of the washing machine door seal is not ideal.

[0033] In view of this, as Figures 1 to 5 ​As shown, a washing machine door seal 10 comprises a sealing lip 11, the sealing lip 11 is adapted to sealingly fit with a washing machine door body 20, and the sealing lip 11 has at least two portions with different thicknesses in the circumferential position of the sealing lip 11.

[0034] In the installation of the sealing lip 11, the different portions of the sealing lip 11 in the circumferential direction are adapted to cooperate with different positions of the washing machine door body 20. Through the above technical solution, since there are at least two portions with different thicknesses in the circumferential position of the sealing lip 11, the portions with different thicknesses can be installed at two positions with different sealing requirements on the washing machine door body 20 to meet the different sealing requirements of the washing machine at different positions.

[0035] The sealing lip 11 (also known as a sealing strip or a sealing edge) on the washing machine door seal 10 is an important component of the washing machine door seal 10, and its main function is to provide a good sealing effect when the washing machine 100 is running to prevent water from leaking from the door gap. The sealing lip 11 can be made of soft rubber or silicone material. The sealing lip 11 can be used to seal the gap between the washing machine door body 20 and the washing machine door seal 10 to ensure the sealing of this part, thereby preventing the washing machine 100 from leaking when it is running.

[0036] Since the sealing lip 11 can be sealingly fitted with the washing machine door body 20, the degree of fit between the two reflects the sealing degree between the two. Therefore, under the premise that other structures of the sealing lip 11 are consistent, when the washing machine door body 20 is pressed against the thicker position of the sealing lip 11, the sealing performance and the sealing degree are better than when the washing machine door body 20 is pressed against the thinner position of the sealing lip 11. In addition, when the washing machine door body 20 is pressed against the thinner position of the sealing lip 11, the closing force required is smaller, and the operator can save more effort when closing the door.

[0037] In the present disclosure, the washing machine 100 is a laundry washing device that has any one or more functions such as washing, drying, and dehydration of laundry.

[0038] In the present disclosure, the sealing lip 11 can have a first portion and a second portion adapted to be arranged in the height direction of the washing machine 100, the first portion is located above the second portion, and the thickness of the second portion is greater than that of the first portion. In this way, the washing machine door seal 10 can be applied to a washing machine in which the washing machine door body 20 is located on the side wall (for example, the front side wall) of the outer shell of the washing machine. The side wall of the outer shell of the washing machine 100 refers to the side part of the outer shell of the washing machine 100 in the height direction, for example, the washing machine 100 with the horizontal drum, and the above-mentioned side wall refers to the side wall of the outer shell opposite to the opening direction of the drum.

[0039] When the washing machine 100 is in operation (such as the operation of a drum washing machine), due to the effect of gravity, the liquid is basically at the lower part of the washing machine 100, and even when the amount of laundry is large, there is only a small amount of liquid at the upper end of the drum of the washing machine 100, so the sealing requirement of the upper part of the washing machine 100 is lower than that of the lower part of the washing machine 100, and therefore, the thickness of the upper part of the washing machine 100 is set to be lower than that of the lower part, so that the thickness of the sealing lip 11 can be designed according to the actual sealing requirement of the washing machine 100. In this way, the sealing requirement of the position of the washing machine door seal 10 can be met, and the closing force can be reduced. The closing force refers to the force that the operator needs to exert on the washing machine door body 20 when closing the washing machine door body 20.

[0040] In the present disclosure, the thickness of the sealing lip 11 can be gradually reduced along the height direction of the washing machine 100. In this way, the sealing requirement of each position of the washing machine door seal 10 can be met as much as possible, and in addition, the gradual transition of the thickness is also convenient for processing.

[0041] When the washing machine 100 is in operation, the amount of water in the drum of the washing machine 100 varies from a small amount to a large amount, and the sealing requirement of the position of the sealing lip 11 along the height direction of the washing machine 100 varies from low to high, and the degree of wear of the sealing lip 11 also varies from low to high, so the thickness of the sealing lip 11 can be gradually reduced along the height direction of the washing machine 100, which can ensure that the sealing lip 11 is set to be suitable for the sealing degree of the washing machine 100, and at the same time, the anti-wear ability of each position of the sealing lip 11 can be met, and at the same time, the closing force of the washing machine 100 can be reduced.

[0042] When the drum of the washing machine 100 rotates, regardless of the amount of clothes, the lower position of the drum of the washing machine 100 is more severely worn due to the effect of gravity, that is, the lower position of the sealing lip 11 needs to improve the anti-wear ability to improve the service life of the sealing lip 11, thereby improving the stability of the position sealing of the washing machine door seal 10 and avoiding that the lip of the sealing lip 11 is torn during washing.

[0043] It can be understood that in other embodiments of the present disclosure, the thickness of the sealing lip 11 along the height direction of the washing machine 100 can also not be continuously gradually changed, and the present disclosure does not limit this.

[0044] The present disclosure does not limit the specific thickness value of each position of the sealing lip 11 in the circumferential direction, which can be designed to be any suitable value as needed.

[0045] Optionally, in an embodiment of the present disclosure, as Figure 3As shown, the thickness of the sealing lip 11 at the lowest position 14 in the height direction of the washing machine 100 can be 2.5mm-4mm. By setting the thickness of the sealing lip 11 at the lowest position 14 in the height direction of the washing machine 100 to be 2.5mm-4mm, the sealing requirement of the washing machine door seal 10 on the position of the washing machine 100 can be met.

[0046] Optionally, in an embodiment of the present disclosure, as shown in Figure 3 As shown, the thickness of the sealing lip 11 at the highest position 15 in the height direction of the washing machine 100 can be 1.5mm-2mm. By setting the thickness of the sealing lip 11 at the highest position 15 in the height direction of the washing machine 100 to be 1.5mm-2mm, the sealing requirement of the washing machine door seal 10 on the position of the washing machine 100 can be met, and the door closing force of the washing machine 100 can be reduced.

[0047] Optionally, in an embodiment of the present disclosure, as shown in Figure 3 As shown, the thickness of the sealing lip 11 at the intermediate position 16 in the height direction of the washing machine 100 (i.e. the middle part of the sealing lip 11 in the height direction of the washing machine 100) can be 1.5mm-3mm. By setting the thickness of the sealing lip 11 at the intermediate position 16 in the height direction of the washing machine 100 to be 1.5mm-3mm, the sealing lip 11 can have a suitable thickness variation rate between the highest position 15 and the lowest position 14, so as to ensure the sealing effect of other parts of the sealing lip 11.

[0048] In the present disclosure, the sealing lip 11 can be located at any suitable position on the washing machine door seal 10, and the present disclosure does not limit the same, as shown in Figure 3 As shown, the washing machine door seal 10 further comprises a door seal body 12 configured in a ring shape, and the sealing lip 11 is arranged on the inner wall 13 of the door seal body 12, i.e. the outer peripheral wall of the sealing lip 11 is integrally formed or connected to the inner peripheral wall of the door seal body 12. In this way, the sealing lip 11 can be conveniently sealed with the corresponding part (the door glass 21 mentioned below) of the washing machine door body 20.

[0049] The present disclosure does not limit the size of the sealing lip 11 protruding from the inner wall 13 of the door seal body 12, and optionally, in an embodiment of the present disclosure, in the radial direction of the door seal body 12, the size of the sealing lip 11 protruding from the inner wall 13 of the door seal body 12 (i.e. the height of the sealing lip 11) can be 6.5mm-8.5mm. In this way, the sealing effect of the sealing lip 11 can be ensured. Among them, the size of the sealing lip 11 protruding from the inner wall 13 of the door seal body 12 at the same height position can be reduced as the thickness of the sealing lip 11 increases, so that the sealing performance of the washing machine door seal 10 can be ensured, and the door closing force of the washing machine 100 can be saved.

[0050] It is understandable that for the same circumferential position of the sealing lip 11, along the height direction of the sealing lip 11, the sealing lip 11 can have the same thickness or different thicknesses.

[0051] According to a second aspect of this disclosure, a washing machine 100 is provided, including a washing machine door 20 and the aforementioned washing machine door seal 10. A sealing lip 11 is adapted to seal against the washing machine door 20, meaning that when the washing machine door 20 is closed, the washing machine door 20 will seal against the sealing lip 11 of the washing machine door seal 10. As mentioned above, by providing the aforementioned washing machine door seal 10 to cooperate with the washing machine door 20, the sealing performance of the washing machine door 20 can be guaranteed.

[0052] In this disclosure, the washing machine door 20 may have any structure suitable for sealing and engaging with the sealing lip 11 of the washing machine door seal 10; this disclosure does not limit this. Optionally, as... Figure 2 and Figure 4 As shown, the washing machine door 20 is provided with a door glass 21, and the door glass 21 is provided with a mating surface 211 suitable for fitting with the sealing lip 11. In this way, the sealing lip 11 can be easily and tightly fitted with the washing machine door 20.

[0053] This disclosure does not limit the specific dimensions of the width of the mating surface 211, as long as it can form a sealing contact area with the sealing lip 11 that meets the requirements. Optionally, in one embodiment of this disclosure, the width of the mating surface 211 (e.g., Figure 5 The width of the area indicated by the W mark is greater than 10mm. Within this width range, the mating surface 211 and the sealing lip 11 can form a sealing contact area that meets the requirements, thus ensuring the sealing effect.

[0054] In this disclosure, the width of the mating surface 211 refers to the width of the portion of the mating surface 211 that is sized to match the sealing lip 11 protruding from the inner wall 13 of the door seal body 12. This width can be set to be greater than 1.5 times the size of the sealing lip 11 protruding from the inner wall 13 of the door seal body 12, so as to facilitate the fit between the sealing lip 11 and the mating surface 211.

[0055] In this disclosure, the washing machine door seal 10 includes a door seal body 12 with an annular structure. In an embodiment where a sealing lip 11 is disposed on the inner wall 13 of the door seal body 12, when the washing machine door 20 and the washing machine door seal 10 are in a fitted state, the included angle between the mating surface 211 and the inner wall 13 (e.g., ...) Figure 5 The position indicated by 'a' can be 20° to 28°. That is, there is an angle between the mating surface 211 and the opening and closing direction of the washing machine door 20. This setting ensures the sealing effect between the washing machine door 20 and the washing machine door seal 10, while also facilitating the opening and closing of the washing machine 100.

[0056] The angle can increase with the increase of the thickness of the sealing lip 11, that is, the thicker the sealing lip 11, the smaller the angle of bending required for the door glass 21, and the sealing performance of the washing machine door seal 10 can be ensured while the closing force of the washing machine 100 is reduced.

[0057] The preferred embodiments of the present disclosure are described in detail above in combination with the drawings, but the present disclosure is not limited to the specific details in the above-described embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0058] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0059] In addition, various different embodiments of the present disclosure can also be combined in any manner, as long as they do not deviate from the idea of the present disclosure, and they should also be considered as disclosed by the present disclosure.
