For example, Chinese utility model patent No. ZL202322649921.8 (authorized publication No. CN220937992U). In order to realize the sealing function of the dishwasher door body, a sealing strip is usually installed at the lower end of the door body. When the door is closed, the sealing strip is in close contact with the inner tank bottom plate to prevent air or impurities from entering. For example, Chinese utility model patent No. ZL202322927554.3 (authorized publication No. CN221105764U) discloses a door body and a dishwasher, wherein the door body comprises a door liner and a sealing strip; the bottom of the door liner is provided with an upwardly bent hook portion, and the hook portion and the surface of the door liner form a clamping cavity; the sealing strip is provided with a clamping portion, the clamping portion extends into the clamping cavity and is clamped with the hook portion, and the sealing strip is elastically deformed when it is pressed; the side wall of the clamping cavity is provided with at least one release opening, and when a plurality of release openings are provided, the plurality of release openings are arranged along the axial direction of the clamping cavity.

[0003] However, this sealing design has some problems in actual application, and the sealing strip is prone to accumulate residues and oil stains. Due to the surface structure characteristics of the sealing strip and the frequent opening and closing of the door body in use, the dirt is difficult to be completely cleaned by a simple method, and generally the door body needs to be disassembled and then the dirt on the sealing strip needs to be removed. This way not only takes time and effort, and is inefficient, but also is difficult for ordinary consumers to disassemble and assemble the door body, which seriously affects the use experience. SUMMARY

[0004] The first technical problem to be solved by the utility model is to provide a door body structure for household appliances with a sealing strip that is easy to clean.

[0005] The second technical problem to be solved by the utility model is to provide a door body structure for household appliances with a sealing strip that is easy to clean and has good cleaning effect.

[0006] The third technical problem to be solved by the utility model is to provide a household appliance comprising the above-mentioned door body structure.

[0007] The utility model discloses a door body structure for household appliance, including the door body, the lower extreme of this door body is equipped with sealing strip, its characterized in that, still be provided with on the door body,

[0008] The guiding channel is in the shape of a long strip.

[0010] The cleaning member can move along the length direction of the sealing strip to clean the dirt attached to the sealing strip.

[0011] The transmission mechanism is used to link the moving block and the cleaning member.

[0012] Further, the moving block can move along the guiding channel in various ways. Preferably, the guiding channel is arranged along the height direction of the door body. During the closing process, the moving block can move downward along the guiding channel under the action of the component force of its gravity along the length direction of the guiding channel, and the cleaning member can move leftward along the length direction of the sealing strip through the transmission mechanism. During the leftward movement of the cleaning member along the length direction of the sealing strip, the cleaning member is subjected to the first elastic force towards the right end of the sealing strip, and the first elastic force increases with the leftward movement of the cleaning member until the door body is completely closed, at which time the cleaning member is stationary at the left end of the sealing strip and the moving block is stationary at the lower end of the guiding channel.

In this way, no additional driving device is needed, and no additional operation is required. The moving block can move downward along the guiding channel through the closing action, and the cleaning member can move leftward along the sealing strip through the transmission mechanism. During the movement, the cleaning of the sealing strip is realized. The moving block and the cleaning member are stationary in the state of complete closing of the door body through the cooperation of the gravity of the moving block and the first elastic force. When the door is opened, the component force of the gravity of the moving block decreases with the increase of the opening angle. In this way, the first elastic force drives the cleaning member to move towards the right end of the sealing strip, and the moving block moves upward along the guiding channel through the transmission mechanism until the door body is completely opened. At this time, the component force of the gravity of the moving block is zero, and the first elastic force acting on the cleaning member is also zero.

[0033] A household appliance comprises a door body structure, and in the embodiment, the household appliance is a dishwasher, specifically a front-opening dishwasher.

[0034] As shown in Figures 1-7 The door body structure comprises a door body 1, and the lower end of the door body 1 is provided with a sealing strip 2.Further, the door body 1 is also provided with a guide channel 30, a moving block 4, a cleaning piece 5 and a transmission mechanism 6.The guide channel 30 is in a strip shape, the moving block 4 is accommodated in the guide channel 30 and can move along the length direction of the guide channel 30.The cleaning piece 5 can move along the length direction of the sealing strip 2 to clean the dirt attached to the sealing strip 2, and the transmission mechanism 6 is used to drive the moving block 4 and the cleaning piece 5.

[0035] The lower end of the door body 1 in the household appliance is rotatably installed on the cabinet of the household appliance, and when opening the door, the door body 1 is rotated downward until the door body 1 is opened to a horizontal state (i.e., the door body 1 is completely opened), and when closing the door, the door body 1 is rotated upward until the door body 1 is in a vertical state (i.e., the door body 1 is completely closed).In the utility model, the door body 1 is provided with the guide channel 30, the moving block 4, the cleaning piece 5 and the transmission mechanism 6, the moving block 4 moves along the length direction of the guide channel 30, and the cleaning piece 5 moves along the length direction of the sealing strip 2 to clean the dirt attached to the sealing strip 2 by using the transmission mechanism 6 to drive the cleaning piece 5, so that the sealing strip 2 is cleaned.It can be seen that, compared with the prior art, the utility model does not need to disassemble the door body 1, but can realize automatic cleaning of the dirt on the sealing strip 2 by moving the moving block 4, which is convenient to operate.

[0036] Further, the moving block 4 can be moved in various ways, and preferably, the guide channel 30 is arranged along the height direction of the door body 1. During the closing process, the moving block 4 can be moved downward along the guide channel 30 under the action of the component force of the gravity of the moving block 4 along the length direction of the guide channel 30, and the cleaning member 5 can be moved leftward along the length direction of the sealing strip 2 by the transmission mechanism 6. During the moving process of the cleaning member 5 along the length direction of the sealing strip 2, the cleaning member 5 is subjected to the first elastic force towards the right end of the sealing strip 2, and the first elastic force increases with the leftward movement of the cleaning member 5. Until the door body 1 is completely closed, the cleaning member 5 is at rest at the left end of the sealing strip 2, and the moving block 4 is at rest at the lower end of the guide channel 30. During the opening process, the component force of the gravity of the moving block 4 is smaller, the cleaning member 5 is moved rightward along the length direction of the sealing strip 2 under the action of the first elastic force, and the first elastic force is smaller. The cleaning member 5 drives the moving block 4 to move upward along the guide channel 30 by the transmission mechanism 6. Until the door body 1 is completely opened, the cleaning member 5 is at rest at the right end of the sealing strip 2, and the moving block 4 is at rest at the upper end of the guide channel 30.

[0037] Thus, the utility model does not need to additionally set a driving device and does not need additional operation, and the moving block 4 can be moved downward along the guide channel 30 by the closing action, and the cleaning member 5 can be moved leftward along the sealing strip 2 by the transmission mechanism 6, the cleaning of the sealing strip 2 is realized during the moving process, and the moving block 4 and the cleaning member 5 are respectively at rest in the state that the door body 1 is completely closed by the cooperation of the gravity of the moving block 4 and the first elastic force, so as to ensure the reliability of the structure in the closed state. When the door is opened, the component force of the gravity of the moving block 4 becomes smaller with the increase of the opening angle, so the cleaning member 5 is moved towards the right end of the sealing strip 2 by the first elastic force, and the moving block 4 is moved upward along the guide channel 30 by the transmission mechanism 6, until the door body 1 is completely opened, the component force of the gravity of the moving block 4 is zero, and the first elastic force of the cleaning member 5 is also zero, so the moving block 4 and the cleaning member 5 are respectively at rest, so as to ensure the reliability of the structure in the opened state. It can be seen that the cleaning of the sealing strip 2 can be realized by the opening and closing actions, and the cleaning member 5 can reciprocate along the length direction of the sealing strip 2 once with the opening and closing actions, so as to improve the cleaning efficiency of the sealing strip 2 and improve the cleaning effect.

[0038] Further, the first elastic force can be realized in various ways, for example, the cleaning member 5 is made of elastic material and deforms itself during the movement along the sealing strip 2 to generate the first elastic force. Preferably, the utility model further comprises an elastic member 7 for enabling the cleaning member 5 to be subjected to the first elastic force. The elastic member 7 is used to generate the first elastic force, which is simple in structure and convenient to realize the change of the first elastic force with the movement of the cleaning member 5.

In this way, the moving block 4 moves the cleaning member 5 along the sealing strip 2 by the pull rope 61 to clean the sealing strip 2. In this embodiment, the left and right sides of the cleaning member 5 are respectively provided with connecting sleeve rings 53, which are convenient for the cleaning member 5 to be connected to the pull rope 61 and the return spring, as shown in the figure. Figure 3 ​

[0041] Further, the transmission mechanism 6 further comprises a guide wheel 62 rotatable about its axis, and the pull rope 61 is wound around the guide wheel 62.
