[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0022] In this disclosure, unless otherwise stated, directional terms such as "first direction" refer to the axial direction of the washing drum door seal structure, i.e., its thickness direction, and "second direction" refers to the radial direction of the washing drum door seal structure. Directional terms such as "inner" and "outer" refer to the inner and outer aspects of a specific structural outline, and terms such as "first" and "second" are used only to distinguish one element from another and do not imply any order or importance.

[0023] Reference Figures 1 to 4As shown, this disclosure provides a washing machine drum door seal structure, which includes a door seal body 1, a mounting portion 2, and a protrusion 3. The door seal body 1 has a door seal opening 10 extending through in a first direction A; one side of the door seal body 1 along the first direction A is used to connect with the drum body (not shown) of the washing machine, and the other side of the door seal body 1 along the first direction A is used to connect with the cabinet body (not shown) of the washing machine. The mounting portion 2 is disposed on the outer wall of the door seal body 1 for installing components (not shown); the outer wall of the door seal body 1 is provided with a clearance groove 11, which is recessed in the first direction A and is disposed opposite to the mounting portion 2 in the first direction A to allow clearance for components. The protrusion 3 is provided protrudingly in the second direction on the outer wall of the door seal body 1, and at least a portion of the protrusion 3 is disposed opposite to the clearance groove 11 in the first direction A; wherein the first direction A and the second direction intersect.

[0024] In the above technical solution, the door seal body 1 is connected between the drum and the cabinet of the washing machine. During the operation of the washing machine, the drum will shake relative to the cabinet. This shaking includes movement in the first direction A, which will pull on the door seal body 1 in the first direction A. Because the outer wall of the door seal body 1 is provided with a relief groove 11 that is recessed in the first direction A to avoid parts, the strength of the door seal body 1 at this point will be reduced, making it prone to breakage. However, by providing a protrusion 3 on the outer wall of the door seal body 1, at least a portion of which is arranged opposite to the relief groove 11 in the first direction A, the door seal body 1 at the location where the relief groove 11 is provided can be structurally reinforced, preventing the door seal body 1 from breaking.

[0025] Optionally, refer to Figure 1 As shown, the door seal body 1 includes a first body segment 12 and a second body segment 13 connected in a first direction A. The outer wall of the second body segment 13 protrudes from the outer wall of the first body segment 12 in a second direction. A mounting portion 2 is disposed on the outer wall of the first body segment 12, and a clearance groove 11 and a protrusion 3 are disposed on the outer wall of the second body segment 13. The door seal body 1 can be constructed in any suitable shape and structure, and this disclosure does not limit it. For example, the first body segment 12 and the second body segment 13 can be constructed as interconnected ring structures with different radial dimensions.

[0026] In one implementation, reference Figure 1As shown, the clearance groove 11 may include a groove bottom wall 111 and a groove side wall 112 connected to each other. The groove bottom wall 111 is connected to the first body section 12, and the groove side wall 112 is connected to the second body section 13. The groove bottom wall 111 and the groove side wall 112 define a first groove 113 and a second groove 114. The first groove 113 is opened in the first direction A and is disposed opposite to the mounting part 2. The second groove 114 is opened in the second direction and communicates with the first groove 113.

[0027] In this embodiment, by providing a first slot 113 and a second slot 114 that are interconnected, the components installed in the mounting part 2 can be accommodated in the clearance slot 11, thereby allowing the components to be cleared and facilitating their installation and arrangement. The bottom wall 111 of the slot can be coplanar with the first body section 12, and the side wall 112 of the slot can be constructed as an arc-shaped wall. However, this disclosure does not limit the specific shapes of the bottom wall 111 and the side wall 112 of the slot.

[0028] Additionally, refer to Figure 1 As shown, the protrusion 3 is connected to the sidewall 114 of the groove and is constructed as an arc-shaped protrusion. The arc-shaped protrusion is provided protrudingly on the second body section 13 and arranged circumferentially thereon. At least a portion of the arc-shaped protrusion is arranged opposite to the clearance groove 11 in the first direction A. In the circumferential direction of the second body section 13, the arc-shaped protrusion gradually approaches the second body section 13 from the middle to the end.

[0029] The arc-shaped protrusion may be partially disposed opposite to the clearance groove 11 in the first direction A, or the arc-shaped protrusion may be disposed entirely opposite to the clearance groove 11 in the first direction A; this disclosure does not limit the specific arrangement or shape of the protrusion 3.

[0030] Optionally, refer to Figures 2 to 4 As shown, the length of the first body edge segment 1001 is the first dimension H1 (refer to...). Figure 4 (Highlighted with bold lines); the sum of the lengths of the second body edge segment 2001 and the first protruding edge segment 2002 is the second dimension H2 (refer to...). Figure 3 (Highlighted in bold); the sum of the lengths of the third body edge segment 3001, the avoidance edge segment 3002, and the second protruding edge segment 3003 is the third dimension H3 (refer to...) Figure 2 (Bold lines); wherein the third dimension H3 is not smaller than the second dimension H2 and / or the first dimension H1.

[0031] In this embodiment, by making the third dimension H3 not less than the second dimension H2 and / or the first dimension H1, that is, by making the length of the cross-sectional edge at the clearance groove 11 not less than the length of the cross-sectional edge of the area where the clearance groove 11 is not provided, the length of the outline edge at the clearance groove 11 is increased, thereby avoiding the problem of tearing and breaking at the clearance groove 11 of the washing drum door seal structure due to the shaking of the drum during the operation of the washing machine.

[0032] In another embodiment, refer to Figures 1 to 4 As shown, the door seal body 1 also includes a first flange 14 and a second flange 15; the first flange 14 is disposed on the side of the first body segment 12 away from the second body segment 13 in the first direction A, and the second flange 15 is disposed on the side of the second body segment 13 away from the first body segment 12 in the first direction A; the first flange 14 is used to connect with the cabinet of the washing machine, and the second flange 15 is used to connect with the outer drum of the washing drum assembly; wherein, the protrusion 3 protrudes from the first flange 14 and the second flange 15 in the second direction.

[0033] In this embodiment, the first flange 14 facilitates the connection between the washing drum door seal structure and the washing machine body. For example, the first flange 14 can be bonded to the washing machine body using adhesive. Similarly, the second flange 15 facilitates the connection between the washing drum door seal structure and the washing machine body. For example, the second flange 15 can be bonded to the washing machine body using adhesive. Furthermore, the protrusion 3 protrudes from the first flange 14 and the second flange 15 in the second direction, further enhancing the strength of the clearance groove 11.

[0034] Additionally, refer to Figure 1 As shown, the washing drum door seal structure may also include an air inlet duct 4; the second body section 13 forms an air inlet that communicates with the door seal opening 10, and the air inlet duct 4 is provided protrudingly on the outer wall of the second body section 13 along the second direction and communicates with the air inlet; the air inlet duct 4 and the clearance groove 10 are staggered in the first direction A, and the air inlet duct 4 is connected to the protrusion 3.

[0035] In this embodiment, firstly, by providing an air inlet duct 4 on the outer wall of the door seal body 1, the air inlet duct 12 can be easily connected to the air duct of the drying device, realizing air guidance and allowing hot air to enter the cylinder, thus shortening the length of the air duct of the drying device. Secondly, by staggering the air inlet duct 4 and the clearance groove 10 in the first direction A, structural interference between the installation of the drying device and its components is avoided, improving the rationality of the structural layout. In addition, the aforementioned protrusion 3 can be connected to the air inlet duct 4, improving the overall integrity and strength of the structure.

[0036] Optionally, refer to Figure 1As shown, the aforementioned mounting part 2 may include a first mounting sleeve 21 and a second mounting sleeve 22. The door seal body 1 has a first mounting hole and a second mounting hole that communicate with the door seal opening 10. The first mounting sleeve 21 is provided on the outer wall of the door seal body 1 in a second direction and communicates with the first mounting hole. The second mounting sleeve 22 is provided on the outer wall of the door seal body 1 in a second direction and communicates with the second mounting hole. One of the first mounting sleeve 21 and the second mounting sleeve 22 is used for the pipe of the sprinkler head to pass through, and the other is used for the connection line of the downlight to pass through.

[0037] That is, the aforementioned clearance groove 11 is used to avoid the sprinkler head pipes and the connection lines of the downlights, ensuring the smooth installation of the sprinkler head and downlights. In addition, this disclosure does not limit the specific structure and shape of the mounting part 2, and it can be constructed with any appropriate shape and structure as long as it can accommodate the installation and arrangement of the sprinkler head pipes and the connection lines of the downlights.

[0038] For example, the washing machine drum door seal structure can be integrally injection molded from rubber, which facilitates processing and molding while ensuring the overall strength and sealing performance of the washing machine drum door seal structure. However, this disclosure does not limit the specific material and molding method of the washing machine drum door seal structure.

[0039] This disclosure also provides a washing machine, which includes a drum, a cabinet, and the aforementioned drum door seal structure.

[0040] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of this disclosure.
