Description

Technical Field

[0001] The utility model relates to the technical field related to dishwashers, in particular to a door sealing structure. 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] The door sealing structure of a traditional dishwasher is generally equipped with an elastic sealing strip at the sealing point of the door opening and closing. The door sealing effect is achieved by relying on the compression of the elastic sealing strip by the door body. As the elastic material weakens after long-term use, the sealing effect of the door body will deteriorate. In addition, the dirt from washed tableware inside the dishwasher can easily hide in the installation groove of the sealing strip. Therefore, the sealing strip needs to be removed for cleaning, which causes great inconvenience to users.

[0004] In summary, there is a need for a water-leakage-proof dishwasher structure that can seal the door without adding an elastic sealing strip. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art in that the elastic sealing strip loses its elasticity after long-term use, the sealing effect of the door body becomes worse, and tableware dirt is easily hidden in the installation groove of the sealing strip, and the sealing strip needs to be disassembled for cleaning. The utility model provides a door body sealing structure that can seal the door body without adding an elastic sealing strip.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A door body sealing structure includes an inner liner and an inner door cover, wherein an inner liner convex rib is provided at the upper end of the inner liner, and the inner liner convex rib is fixed to the upper end surface of the inner liner, and a rib slot matching the inner liner convex rib is provided at the bottom of the inner door cover, and the inner liner convex rib and the rib slot are plugged in up and down.

[0008] The inner liner and inner door cover are connected vertically through the cooperation of the inner liner ribs and the rib slots, which has a simple structure and is easy to operate. The inner liner ribs on the upper end surface of the inner liner and the rib slots on the bottom of the inner door cover are sealed vertically, which can effectively prevent the washing water from rushing out of the cavity. This solution can seal the door body without adding elastic sealing strips, which is simple, reliable and lower in cost.

[0009] Preferably, a water collection trough is provided at the upper end of the inner container. The water collection trough is located on the inner annular wall of the inner container, and the inner container rib is fixed to the bottom surface of the water collection trough. The water collection trough design can collect a very small amount of water that may overflow the inner container rib in the water collection trough, thereby preventing the wash water from leaking out.

[0010] Preferably, the ribs of the inner container are provided with a reflux hole, and the bottom of the water collection tank is connected to the inner wall of the inner container through the reflux hole. The design of the reflux hole can automatically drain the water in the water collection tank back into the inner container, thereby improving the waterproof sealing effect.

[0011] Preferably, the lower end of the inner door cover is provided with an inner door cover rib and a drainage rib. Both the inner door cover rib and the drainage rib are fixed to the lower end surface of the inner door cover. The drainage rib is located inward of the inner door cover rib, and the rib slot is formed by the inner side wall of the inner door cover rib, the lower end surface of the inner door cover, and the outer side wall of the drainage rib. The drainage rib is designed to block the connecting gap between the inner liner rib and the rib slot from the inside, automatically draining water that hits the inner door cover wall into the inner liner, further improving the waterproof sealing effect.

[0012] Preferably, the inner side wall of the rib of the inner container is provided with a fitting groove matching the drainage rib. The matching design of the drainage rib and the fitting groove improves the assembly stability.

[0013] The beneficial effects of the utility model are: simple structure, easy operation; the door body can be sealed without adding elastic sealing strips, the structure is simple and reliable, and the cost is lower; the waterproof sealing effect is improved; and the assembly stability is improved.
