Technical Field

[0001] The utility model relates to the technical field related to dishwashers, in particular to an anti-overflow component at a door corner of a dishwasher. Background Art

[0002] Dishwashers are kitchen helpers in homes and businesses. They are devices used to automatically wash bowls, chopsticks, plates, dishes, knives, forks and other tableware to help people reduce the burden of housework.

[0003] When the dishwasher is working, the heated water is pressurized by the washing pump and then flushed onto the dishes. The internal cavity of the dishwasher is high temperature and high humidity, so the sealing of the door opening and closing is more critical. The quality of the door sealing affects the water leakage of the dishwasher and the user experience. In severe cases, it may cause the dishwasher to leak and alarm, and the dishwasher cannot work normally.

[0004] The existing dishwasher door sealing strip is of the inserted type and is not pressed tightly, so that the sealing strip is easy to fall off during use, resulting in a loose seal and water leakage. Moreover, the door sealing strip of today's dishwashers is usually placed on the door body, which can easily cause the sealing strip to fail during long-term use.

[0005] In summary, there is currently a need for a dishwasher door corner anti-overflow assembly that can improve the anti-leakage effect. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1-3 In the embodiment described above, a dishwasher door corner anti-overflow assembly includes a body 1 and a door 2. A body opening 3 matching the door 2 is provided on the side of the body 1. The door 2 is installed at the body opening 3 and is movably connected thereto. Figures 4-5As shown, a sealing frame 4 and a sealing strip 5 are provided at the body opening 3, and the sealing frame 4 and the body opening 3 are riveted and fixed. A sealing strip limiting groove 6 is provided on the side of the sealing frame 4 close to the machine door 2, and the side of the sealing strip 5 away from the machine door 2 is installed and fixed in the sealing strip limiting groove 6. A plurality of fins 7 are provided on the side of the sealing strip 5 away from the machine door 2, and the fins 7 are distributed on the inner and outer sides of the sealing strip 5. The fins 7 on both sides of the sealing strip 5 are arranged layer by layer from the inside to the outside along the direction close to the machine door 2, the inner fin 7 is in contact with the inner wall of the body opening 3, and the outer fin 7 is in contact with the groove wall of the sealing strip limiting groove 6.

[0028] An extrusion sheet 8 is provided on the side of the sealing strip 5 close to the machine door 2 , and the extrusion sheet 8 is inclined toward the inner side of the sealing strip 5 from the end away from the machine door 2 to the end close to the machine door 2 .

[0029] The interior of the sealing strip 5 is hollow.

[0030] like Figures 8-9 As shown, the sealing strip 5 is made of elastic material, and a convex hull 9 is provided at the bottom rounded corner of the body opening 3, and the convex hull 9 is located on the outside of the sealing strip 5.

[0031] The sealing strip 5 is made of elastic material, and the groove wall shape of the sealing strip limiting groove 6 is L-shaped.

[0032] like Figures 6-7 As shown, a sealing strip 10 is provided at the bottom of the door 2. One side of the sealing strip 10 is riveted to the door 2. The other side of the sealing strip 10 faces the bottom side of the machine opening 3 and is provided with a plurality of fins 11. The fins 11 are arranged layer by layer from the outside to the inside along the direction close to the machine body 1. The sealing strip 5 and the sealing strip 10 cooperate with each other to achieve a full-circle seal between the machine body 1 and the door 2.

[0033] By arranging the fins 7 layer by layer on both sides of the sealing strip 5, a multi-layer sealing surface is formed to seal the gap between the inner wall of the body opening 3 and the sealing strip 5, and the gap between the groove wall of the sealing strip limiting groove 6 and the sealing strip 5, thereby preventing water from spraying out from the sealing frame 4.

[0034] When the door 2 is closed, the extrusion piece 8 arranged obliquely on the sealing strip 1 5 will automatically press on the door 2 to seal it. At the same time, the several fins 2 11 on the sealing strip 2 10 will abut against the bottom side of the machine body opening 3 to form a multi-layer seal, which can also effectively prevent the flow of water from rushing out. The full circle seal between the machine body 1 and the door 2 is achieved through the cooperation between the sealing strip 1 5 and the sealing strip 2 10.

[0035] In order to better seal, the sealing strip 5 is made of elastic material. This design method will easily cause a gap to form between the bottom corner of the body opening 3 and the sealing strip 5, causing high-temperature water to spray out from the gap. The present application adds a convex bump 9 to block the high-temperature water sprayed from the gap between the bottom corner of the body opening 3 and the sealing strip 5, or sets the bottom of the sealing frame 4 into an L shape to fix the bottom of the sealing strip 5, which can effectively prevent high-temperature water from spraying out from the gap between the bottom corner of the body opening 3 and the sealing strip 5.

[0036] On the other hand, in order to make it easier for the lower bowl basket inside the body 1 to be pulled out onto the door 2, a slope is generally provided at the bottom of the door 2 to facilitate the pushing and pulling of the wheels of the lower bowl basket. However, this slope will cause the bottom of both sides of the door 2 to not be completely in contact with the sealing strip 5. Therefore, the present application designs the parts where the bottom of both sides of the door 2 and the sealing strip 5 are in contact with each other to be flat, which can make the sealing effect of the door 2 better, prevent water and steam from leaking, and increase the sealing reliability of the door 2.
