TECHNICAL FIELD
[0001] The utility model relates to a dishwasher technical field, concretely relates to a dishwasher with sealing structure. BACKGROUND
[0002] In the existing kitchen appliances, such as steam ovens, steam ovens, cleaning machines, etc., all include a box body with a functional inner cavity and a door body provided at the opening of the box body to open or close the opening. The structure of the cleaning machine includes a door body and an inner container forming a washing space, and a washing mechanism is arranged in the washing space. In order to ensure that the washing water does not leak from the gap between the tank body and the door body during washing, a sealing structure is provided between the periphery of the door body and the inner container.
[0003] For the top-opening cleaning machine (i.e., the door body cover is provided at the top opening of the inner container), some current solutions are to provide an integrally formed annular sealing ring on the door body, such as the Chinese invention patent disclosed in patent application No. CN202122957229.2 (publication No. CN216417111U) "Sealing structure of sink type dishwasher door".
[0004] However, for the side-opening cleaning machine (i.e., the door body is rotatably arranged at the side opening of the inner container), the inner door bottom is located in the inner container, the upper part of the inner door can swing forward and backward, and the inner door side wall has an avoidance opening adjacent to the bottom part thereof to avoid the inner container during rotation, resulting in that the side wall and the bottom wall of the inner door are not completely connected, i.e., there is no annular structure on the inner door to fit the integrally formed annular sealing ring. If the integrally formed annular sealing ring is arranged in the inner container, a frame capable of surrounding a receiving groove (for receiving the sealing ring) on the bottom wall of the inner container needs to be riveted on the bottom wall of the inner container, and the bottom wall of the inner container is usually not a flat surface, so riveting the frame will be more difficult.
[0005] Therefore, the current embedded dishwasher door sealing basically adopts left, right and upper three edge sealing strips installed on the inner container assembly to form end face sealing with the inner door, such as the Chinese invention patent disclosed in patent application No. CN201520328405.8 (publication No. CN204850983U) "Dishwasher door sealing structure and dishwasher comprising the same", the door sealing structure includes a sealing strip, and the sealing strip includes an upper sealing strip, a left sealing strip and a right sealing strip, the upper sealing strip, the left sealing strip and the right sealing strip are welded into one body.
[0006] The bottom sealing strip is arranged on the door body, such as the bottom sealing strip for a dishwasher disclosed in the Chinese patent application No. CN200920050045.4 (publication No. CN201346193Y), which comprises a body clamped on the inner door and a first sealing soft foot and a second sealing soft foot for sealing the bottom disc of the inner container, wherein the included angle θ between the first sealing soft foot and the second sealing soft foot is 90°≤θ≤180°, the first sealing soft foot is arranged at the bottom of the bottom disc of the inner container, and the second sealing soft foot is arranged at the side of the bottom disc of the inner container. In the application, the included angle θ between the two sealing soft feet of the sealing strip is 90°≤θ≤180°, the first sealing soft foot is arranged at the bottom of the bottom disc of the inner container, and the second sealing soft foot is arranged at the side of the bottom disc of the inner container. When the inner door is closed, the two sealing soft feet are pressed against the inner wall of the bottom disc of the inner container at the same time, and the sealing is tighter under the impact of water flow.
[0007] The current sealing structure has no sealing at the corners of the left and right sealing strips and the bottom sealing strip, that is, the upper, left, right and bottom sealing strips do not form a closed ring in the closed state of the door body, and there are sealing dead angles at the left and right corners of the inner container. When cleaning, water will enter the area outside the bottom sealing strip of the inner container from the left and right sealing dead angles. If the water flow is strong, there is a risk of overflow from the cleaning machine.
[0008] In addition, the door body of the dishwasher is generally composed of an inner door body and an outer door body (as shown in the above patent), and the two door bodies are connected to form a whole. However, there is a gap between the inner door body and the outer door body. If the sealing between the inner container and the door body is not good, a large amount of water vapor will enter between the inner and outer doors when the cleaning machine is cleaning, which will damage the electrical elements installed in the door body. In addition, water will also flow out from the gap between the inner and outer doors and drop onto the table top. Practical new type content
