[0035] The following will describe in detail the specific embodiments of the present disclosure with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and understanding the present disclosure, and are not used to limit the present disclosure.

[0036] In the present disclosure, unless otherwise stated, the orientation terms such as "upper" and "lower" are usually defined in the direction of the drawing surface of the accompanying drawings, and "inner" and "outer" refer to the inside and outside of the relevant components. In addition, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0037] In the description of the present disclosure, it should also be noted that unless otherwise clearly specified and limited, the terms "arranged" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0038] With the development of washing machines, more and more washing machines are equipped with a drying function. The washing machine with a drying function has a drying device, which can generate hot air and blow it into the washing drum to achieve the drying of clothes.

[0039] In the related art, the drying channel of the drying device on the washing drum is directly connected to the door seal, and the air intake volume is limited by the size of the connection between the drying channel and the door seal, resulting in a small air intake volume and affecting the drying effect. Moreover, since the drying channel is directly connected to the door seal, it is necessary to design a relatively long drying channel, and it is not easy to operate during assembly.

[0040] For this reason, as Figures 1 - 3 shown, one aspect of the present disclosure provides a door seal for a washing drum, including a door seal body 1 and an air intake duct 12 formed in the door seal body 1.

[0041] An air intake opening is formed in the door seal body 1, and the door seal body 1 is used to be connected to the barrel of the washing drum. The air intake duct 12 is communicated with the air intake opening, and the air intake duct 12 is used to be connected to the air duct 21 of the drying device. The air intake duct 12 extends in a first direction, where the first direction is set as the horizontal direction.

[0042] Among them, the air intake duct 12 is communicated with the air intake opening, so that the hot air generated by the drying device is blown into the barrel of the washing drum through the air duct 21, the air intake duct 12 and the air intake opening.

[0043] In the above technical solution, the provided air inlet duct 12 can be conveniently connected to the air duct 21 of the drying device to achieve air guiding, enabling hot air to enter the interior of the laundry drum. This can shorten the length of the air duct 21 of the drying device, facilitating the assembly of the drying device with the laundry drum and the door seal, making the operation simple. By extending the air inlet duct 12 in the first direction, the size of the air inlet duct 12 can be increased as much as possible without being limited by the connection between the air duct 21 of the drying device and the door seal, thereby increasing the air volume entering the interior of the laundry drum. In addition, the air inlet duct 12 and the door seal body 1 are integrally formed, facilitating manufacturing.

[0044] Optionally, in an embodiment of the present disclosure, in the second direction, the air inlet duct 12 has a first outer wall surface 121 and a second outer wall surface 122 disposed opposite to each other, and the first outer wall surface 121 and / or the second outer wall surface 122 of the air inlet duct 12 is parallel to the first direction. Herein, the second direction is set as the vertical direction. By setting it in this way, the air volume flowing through the air inlet duct 12 towards the air inlet can be kept consistent, realizing the blowing of hot air with a large air volume.

[0045] In some examples, the first outer wall surface 121 of the air inlet duct 12 is parallel to the first direction, that is to say, the first outer wall surface 121 of the air inlet duct 12 is horizontally arranged, and the second outer wall surface 122 of the air inlet duct 12 can be inclined. In other examples, the second outer wall surface 122 of the air inlet duct 12 is parallel to the first direction, that is to say, the second outer wall surface 122 of the air inlet duct 12 is horizontally arranged, and the first outer wall surface 121 of the air inlet duct 12 can be inclined. Additionally, in some examples, both the first outer wall surface 121 and the second outer wall surface 122 of the air inlet duct 12 are parallel to the first direction, that is to say, both the first outer wall surface 121 and the second outer wall surface 122 of the air inlet duct 12 are horizontally arranged. Thus, the air inlet duct 12 can be a rectangular duct.

[0046] Optionally, in another embodiment of the present disclosure, in the second direction, the air inlet duct 12 has a first outer wall surface 121 and a second outer wall surface 122 disposed opposite to each other, and both the first outer wall surface 121 and the second outer wall surface 122 of the air inlet duct 12 are inclined towards the door seal body 1. The air inlet duct 12 can be configured as a funnel-shaped structure.

[0047] Optionally, in an embodiment of the present disclosure, the door seal body 1 is configured as an annular structure, the axis of the door seal body 1 extends in the third direction, the air inlet is located on one side of the door seal body 1 in the first direction, and the air inlet duct 12 extends away from the door seal body 1. Wherein, the third direction is set as the horizontal direction, and the first direction is perpendicular to the third direction. By setting like this, it can realize the conveyance of hot air to the barrel of the washing tub from the side, and the barrel of the washing tub can be arranged at a position close to the top of the housing of the washing machine, avoiding interference. It is also possible to arrange other components above the barrel of the washing tub, making the layout of the internal components of the washing machine more flexible.

[0048] Wherein, one side of the door seal body 1 in the third direction is connected to the barrel of the washing tub, and the door seal body 1 has a certain width in the third direction, so that an air inlet can be opened. Wherein, in the third direction, the width of the air inlet can be slightly smaller than the width of the door seal body 1, so as to increase the air intake. At the same time, in the third direction, the width of the air inlet duct 12 can be the same as the width of the air inlet, maintaining the air intake.

[0049] Optionally, in an embodiment of the present disclosure, in the second direction, the first outer wall surface 121 of the air inlet duct 12 is located above the second outer wall surface 122 of the air inlet duct 12, and the door seal body 1 has a vertex tangent line 13 that extends in the first direction. Wherein, the first outer wall surface 121 of the air inlet duct 12 is close to and lower than the vertex tangent line 13, or the first outer wall surface 121 of the air inlet duct 12 coincides with the vertex tangent line 13. By setting like this, the first outer wall surface 121 of the air inlet duct 12 can be set as high as possible, so as to increase the cross-sectional area of the air inlet duct 12, thereby increasing the air intake. And the first outer wall surface 121 of the air inlet duct 12 does not exceed the vertex tangent line 13, which can also avoid installation interference in the second direction and avoid problems such as contact or collision with the components above. Especially when the barrel of the washing tub rotates, there will be vibrations, and the air inlet duct 12 will also follow and have slight vibrations, which can improve the overall reliability.

[0050] It should be noted that the coincidence of the first outer wall surface 121 of the air inlet duct 12 and the vertex tangent line 13 means that the first outer wall surface 121 of the air inlet duct 12 is flush with the vertex of the door seal body 1 and does not exceed the vertex of the door seal body 1 in the second direction.

[0051] Optionally, in an embodiment of the present disclosure, in the second direction, the linear distance between the first outer wall surface 121 of the air inlet duct 12 and the vertex tangent line 13 is less than or equal to 10 mm. By setting like this, the cross-section of the air inlet duct 12 can be increased as much as possible while avoiding interference. In some examples, the linear distance between the first outer wall surface 121 of the air inlet duct 12 and the vertex tangent line 13 can be 0, 5 mm, etc.

[0052] Optionally, in an embodiment of the present disclosure, the door seal body 1 has a median line 14 that extends in the first direction and passes through the center of the door seal body 1. The second outer wall surface 122 of the air inlet duct 12 is close to the median line 14 or coincides with the median line 14. By setting it in this way, the second outer wall surface 122 of the air inlet duct 12 can be arranged as low as possible, which can increase the cross-sectional area of the air inlet duct 12, thereby increasing the air intake volume. And the second outer wall surface 122 of the air inlet duct 12 does not exceed the median line 14, which can avoid installation interference in the second direction and avoid problems such as contact or collision with the components below. In particular, when the cylinder of the washing tub rotates, there will also be vibrations, and the air inlet duct 12 will also follow with slight vibrations, which can improve the overall reliability. In some examples, in the second direction, the linear distance between the second outer wall surface 122 of the air inlet duct 12 and the median line 14 is 0 mm - 30 mm. It can be specifically selected according to the actual situation, and there is no excessive limitation here. The coincidence of the second outer wall surface 122 of the air inlet duct 12 and the median line 14 means that in the second direction, the second outer wall surface 122 and the median line 14 are at the same horizontal height.

[0053] Optionally, in an embodiment of the present disclosure, the air inlet duct 12 includes a first pipe section 123 and a second pipe section 124. The first pipe section 123 is configured as a straight pipe section. The first end of the first pipe section 123 is used to connect with the air duct 21 of the drying device. The second end of the first pipe section 123 is connected to the first end of the second pipe section 124. The second end of the second pipe section 124 is configured as an arc structure, and the second end of the second pipe section 124 fits against the outer wall of the door seal body 1 and communicates with the air inlet. By setting it in this way, it is convenient for the air inlet duct 12 to be respectively adapted and connected to the air duct 21 of the drying device and the air inlet, ensuring the diversion and transportation of hot air and ensuring the air volume of the transported hot air.

[0054] Optionally, in an embodiment of the present disclosure, a connection part 125 is provided at the first end of the first pipe section 123. The connection part 125 is used for detachably connecting with the air duct 21 of the drying device. By providing the connection part 125, it is convenient to connect or separate the first end of the first pipe section 123 with the air duct 21 of the drying device, which is convenient for assembly and can also be used for later maintenance. In some examples, the connection part 125 can be an ear. There is a connection hole on the ear, and a paired ear can also be provided on the corresponding air duct 21 of the drying device. There is a connection hole on the paired ear, and the connection is realized by passing a bolt through the two connection holes. In other examples, the connection part 125 can be a buckle, and the air duct 21 of the drying device can be snap-connected with the first end of the first pipe section 123.
