[0045] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0046] Generally, a washing machine may include a housing, an outer tub, an inner tub, a door body, and a door seal 100 .

[0047] Both the inner drum and the outer drum are located in the shell, and the outer drum is sleeved on the outside of the inner drum, wherein the inner drum is rotatably connected to the shell, and the outer drum is fixedly connected to the shell. When the washing machine is working, the clothes are placed in the inner drum, and the inner drum rotates to achieve operations such as washing, spinning or drying.

[0048] The door body can also be called the washing machine door, which is rotatably connected to the shell to achieve the opening or closing of the door body. When the door body is open, the user can put in and put out clothes. When the door body is closed, the washing machine washes, spins or dries the clothes.

[0049] The door seal 100 is connected to the housing and is used to seal the gap between the door body and the housing when the door body is closed to prevent water or air leakage when the washing machine is working.

[0050] The present disclosure provides a door seal 100, see Figure 1 and Figure 2 The door seal 100 includes a first door seal portion 1 and a second door seal portion 2. The first door seal portion 1 and the second door seal portion 2 both have an annular structure and can be coaxially arranged.

[0051] Among them, the first door sealing part 1 has two opposite ends, namely the first end 11 of the first door sealing part 1 and the second end 12 of the first door sealing part 1. The first end 11 of the first door sealing part 1 is used to be connected to the outer drum of the washing machine. Further, the first end 11 of the first door sealing part 1 is used to be connected to an end of the outer drum of the washing machine close to the door body, and the second end 12 of the first door sealing part 1 is used to be connected to the shell of the washing machine. In this way, a fixed connection between the first door sealing part 1 and the shell is realized.

[0052] The second door sealing part 2 is connected to the second end 12 of the first door sealing part 1 , that is, the second door sealing part 2 is arranged at an end of the first door sealing part 1 close to the door body.

[0053] For the position setting between the first door sealing part 1, the second door sealing part 2 and the door body, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The second door sealing part 2 is located between the first door sealing part 1 and the door glass 200. Figure 3 , Figure 5 , Figure 6 The structure between the first door seal 1, the second door seal 2 and the door glass 200 when the door is closed is shown. When the door is closed, the door seal 100 and the door glass 200 are pressed and attached to each other, thereby achieving sealing.

[0054] Understandably, Figure 5 and Figure 6 Only one possible structure after the door body is closed is shown, and the embodiment of the present disclosure does not specifically limit the deformation of the door seal 100 after the door body is closed.

[0055] The material of the door seal 100 (including the first door seal part 1 and the second door seal part 2) in the embodiment of the present disclosure can be any material used for sealing, for example, it can be a rubber material, etc., and the embodiment of the present disclosure does not specifically limit this.

[0056] See also Figure 6 The second door sealing portion 2 has an air duct 21.

[0057] The inlet end 211 of the air duct 21 is used to be connected to a fan, wherein the fan may be an independently arranged fan or a built-in fan of the washing machine, which is not specifically limited in the embodiments of the present disclosure.

[0058] The air outlet direction of the outlet end 212 of the air duct 21 is toward the first end 11 of the first door seal part 1. After the door seal 100 is installed in the washing machine, the air outlet direction of the outlet end 212 of the air duct 21 is from the end of the outer drum close to the door body to the end of the outer drum away from the door body.

[0059] The controller of the washing machine can be electrically connected to the fan. When it is detected that the user puts clothes into the washing machine, the fan is controlled to start. In this way, the fan can drive air from the inlet end 211 of the air duct 21 into the air duct 21, and then blow it out from the outlet end 212 of the air duct 21. At this time, if clothes fall on the door seal 100 close to the door body, the wind blown out from the outlet end 212 of the air duct 21 can blow the clothes at this position into the deep of the inner drum, that is, blow the clothes away from the door body, so as to avoid the clothes being clamped by the door glass and the door seal 100 when the door body is closed. In this way, when the washing machine works to make the inner drum rotate, the clothes and components such as the door seal 100 will not be damaged, thereby improving the user experience and the service life of components such as the door seal 100 in the washing machine. There will be no impact on the normal operation of the washing machine by the clamped clothes, thereby improving the working stability of the washing machine.

[0060] It can be understood that the controller can detect whether the door body is currently in an open state or a closed state through a sensor, and can control the fan to work all the time when it is detected that the door body is in an open state. Of course, in the embodiment of the present disclosure, the control method can also be any other reasonable method, and the embodiment of the present disclosure does not specifically limit this.

[0061] The structures of the first door sealing part 1 and the second door sealing part 2 in the embodiment of the present disclosure can be any reasonable structures. Several possible structures are introduced below:

[0062] See also Figure 7 The first end 11 of the first door sealing part 1 has a first card slot 13, and the first card slot 13 is used to be connected with the outer drum of the washing machine. The second end 12 of the first door sealing part 1 has a second card slot 14, and the second card slot 14 is used to be connected with the shell of the washing machine.

[0063] The shape of the first slot 13 can be any reasonable shape. For example, the first slot 13 can be a T-shaped groove, also called a T-shaped groove. Correspondingly, the outer drum of the washing machine engaged with the first slot 13 has a T-shaped protrusion structure, which is adapted to engage with the first slot 13, thereby achieving the connection between the first end 11 of the first door sealing part 1 and the outer drum. Of course, the first slot 13 can also have other reasonable shapes, which are not specifically limited in the embodiments of the present disclosure.

[0064] In a possible implementation, a plurality of teeth 131 are provided on the inner side wall of the first slot 13, so that the connection strength and sealing between the first slot 13 and the outer drum of the washing machine are improved.

[0065] The notch direction of the first slot 13 may be from the end of the outer tube close to the door body toward the end of the outer tube away from the door body, that is, Figure 7 The direction a in the figure facilitates the installation between the first door sealing part 1 and the outer cylinder.

[0066] The shape of the second card slot 14 may also be any reasonable shape. For example, the second card slot 14 may be a rectangular groove, or may be a T-shaped groove. The embodiment of the present disclosure does not specifically limit this.

[0067] In a possible implementation, the inner side wall of the second slot 14 may have a plurality of teeth (not shown in the figure), so as to improve the connection strength and sealing between the second slot 14 and the housing of the washing machine.

[0068] The slot direction of the second slot 14 can also be direction a, or, it can be tilted at a certain angle on the basis of direction a, so that the slot direction has a component in direction a, but there is an angle between it and direction a, so that during installation, the first end 11 of the first door sealing part 1 and the second end 12 of the first door sealing part 1 have the same installation direction and are both installed in direction a, thereby improving the convenience of installation. Since there is an angle between the second end 12 of the first door sealing part 1 and direction a, the connection strength between the first slot 13 and the outer drum, and between the second slot 14 and the shell of the washing machine is improved.

[0069] In a possible implementation, the second door sealing portion 2 and the first door sealing portion 1 may be an integrally formed structure.

[0070] In another possible implementation, see Figure 6 , Figure 7 and Figure 8 The second end 12 of the first door sealing part 1 has a protruding structure 15, and the second door sealing part 2 has a third card slot 22. The protruding structure 15 is adapted to be engaged with the third card slot 22, thereby achieving the connection between the first door sealing part 1 and the second door sealing part 2. It can be understood that, referring to Figure 6 When the second end 12 of the first door sealing portion 1 has a second card slot 14 , the second card slot 14 can be arranged on the protruding structure 15 .

[0071] The shape of the third slot 22 can be any reasonable shape. For example, the third slot 22 can be a C-shaped groove, also called a C-shaped groove, or a T-shaped groove, etc. The embodiment of the present disclosure does not specifically limit this.

[0072] In one possible implementation, see Figure 6 and Figure 8 The second door sealing part 2 may include a mounting part 23, a flow equalizing part 24 and a flow guiding part 25. The mounting part 23, the flow equalizing part 24 and the flow guiding part 25 all have an annular structure, and the mounting part 23, the flow equalizing part 24 and the flow guiding part 25 are sequentially connected to form the third card slot 22 mentioned above.

[0073] The flow equalizing portion 24 has a first cavity 241 and an opening 242. The first cavity 241 is connected to the opening 242. The opening 242 is the inlet end 211 of the above-mentioned air duct 21, that is, the opening 242 is used to connect with the fan. When the fan is working, it can drive air from the opening 242 into the first cavity 241.

[0074] The air guide portion 25 has a second cavity 251, and the inlet end of the second cavity 251 is connected to the first cavity 241 to form the above-mentioned air duct 21, that is, the first cavity 241 and the second cavity 251 together constitute the air duct 21. The outlet end of the second cavity 251 is the outlet end 212 of the above-mentioned air duct 21, and the air outlet direction of the outlet end of the second cavity 251 is the direction toward the first end 11 of the first door sealing portion 1.

[0075] In this way, the fan can drive air from the opening 242 into the first cavity 241, then into the second cavity 251, and then blow out from the outlet end of the second cavity 251. At this time, if clothes fall on the door seal 100 close to the door body, the wind blown out from the outlet end of the second cavity 251 can blow the clothes at this position into the deep of the inner drum, that is, blow the clothes away from the door body, so as to avoid the clothes being clamped by the door glass and the door seal 100 when the door body is closed. In this way, when the washing machine works to make the inner drum rotate, the clothes and components such as the door seal 100 will not be damaged, thereby improving the user experience and the service life of components such as the door seal 100 in the washing machine. There will be no impact on the normal operation of the washing machine by the clamped clothes, thereby improving the working stability of the washing machine.

[0076] Furthermore, the provision of the first cavity 241 allows the air entering from the opening 242 to flow more quickly to various positions of the annular structure where the flow equalizer 24 is located, and then flow out through the second cavity 251, thereby improving the uniformity of the air flowing out from the outlet end of the second cavity 251. Fig. 9 , Fig. 9 A simulation effect diagram of the second door sealing part 2 is shown, and it can be seen that when the fan drives the dynamic air to enter the air duct 21 from the opening 242, the gas flowing out from the outlet end 212 of the air duct 21 is relatively uniform.

[0077] In one possible implementation, the opening 242 can be located at a position of the flow equalizing portion 24 away from the guide portion 25, so that the distance between the opening 242 and the inlet end of the second cavity 251 is increased, so that the air entering the first cavity 241 can flow more evenly to various positions of the annular structure, thereby improving the uniformity of the air flowing out from the outlet end of the second cavity 251.

[0078] It can be understood that the above is only an example of several possible structures of the first door sealing part 1 and the second door sealing part 2 in the embodiment of the present disclosure. The first door sealing part 1 and the second door sealing part 2 in the embodiment of the present disclosure may also be any other reasonable structure, and the embodiment of the present disclosure is not limited to this.

[0079] The embodiment of the present disclosure further provides a washing machine, which includes a door seal 100 of any one of the above structures, an outer drum, a shell and a fan.

[0080] The first end 11 of the first door seal part 1 of the door seal 100 is connected to the outer tube, the second end 12 of the first door seal part 1 is connected to the shell, the inlet end 211 of the air duct 21 on the second door seal part 2 of the door seal 100 is connected to the fan, and the outlet end 212 of the air duct 21 of the second door seal part 2 is directed from the end of the outer tube close to the door body toward the end of the outer tube away from the door body.

[0081] The above-mentioned washing machine may be a drum washing machine, or may be other types of washing machines having the above-mentioned structure, which is not limited in the embodiments of the present disclosure.

[0082] The technical solution provided by the embodiments of the present disclosure includes at least the following beneficial effects:

[0083] The disclosed embodiment provides a door seal 100. When the user puts clothes into the washing machine and closes the door, the fan can drive air to enter the air duct 21 from the inlet end 211 of the air duct 21, and then blow air from the outlet end 212 of the air duct 21 toward the first end 11 of the first door seal part 1. In this way, the clothes that fall on the door seal 100 near the door body can be blown deep into the inner drum, thereby preventing the door body and the door seal 100 from clamping the clothes when the door is closed, and thus preventing damage to the clothes and the door seal 100, etc., thereby improving the service life of components such as the door seal 100 in the washing machine and improving the working stability of the washing machine.

[0084] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
