Description

Corner plate mounting structure for opening of inner container of dish washing machine and dish washing machine with corner plate mounting structure

Technical Field

The application belongs to the technical field of dish-washing machines, and particularly relates to an angle plate mounting structure for an opening of an inner container of a dish-washing machine and the dish-washing machine.

Background

In the existing dish washing machine on the market, an inner container of the dish washing machine is generally of a five-sided box body structure, and one side of the inner container is provided with an opening for covering a door body of the dish washing machine. According to production requirements, the outer parts of the left upper corner and the right upper corner of the opening of the inner container are required to be arranged into right angles, and round corners are arranged inside the two side upper corners, namely, the part positioned in the inner container inner cavity is a round corner, so that the shape of the inner container inner cavity of the dish-washing machine is matched, and the whole machine is attractive. In order to obtain the external right angle of the left upper corner and the right upper corner on the inner container opening and the internal fillets of the two upper corners, the left upper corner and the right upper corner of the inner container opening are respectively provided with an angle plate which is in accordance with the shape, the outer side of the angle plate is provided with a right-angle side, the inner side of the angle plate is provided with a round-angle side, and the inner container opening production requirement of the dish-washing machine is further matched.

However, in practical application, because the inner container is a sheet metal part, and the size of the part is large, the size of the inner container in the left-right direction is difficult to control, so that when the angle plate is installed on the inner container, the width of the angle plate cannot be completely matched with the size of the left upper corner and the right upper corner of the opening of the inner container, and gaps are easy to exist between the angle plate and the plate of the inner container, thereby seriously affecting the appearance of the dish-washing machine.

In order to fix the corner plate to the opening of the inner container, a garnish such as a flange is generally provided around the periphery of the opening. The turned edges are used as connection points with the angle plates, and the angle plates are further arranged on the upper corners on two sides of the opening of the inner container. Because the angle plate is a fitting superposed on the liner, the punching edge of the angle plate has a fall with the flanging of the liner, so that a hand scraping position which hurts people is easily formed, and the safety is poor. The angle plate and the inner container flanging are generally connected in a riveting or welding mode and can be implemented only by special processing equipment, so that the processing cost is increased. If a simple screw fixing mode is adopted, the screw head is easily exposed and convexly arranged on the opening of the liner, so that a hand scraping part which hurts people is easily formed, or a door body which is frequently opened and closed on the opening of the liner is damaged.

Therefore, the angle plate mounting structure on the opening of the inner container of the dish washing machine in the prior art still has a plurality of defects, and is a technical problem which is urgently needed to be perfected by dish washing machine manufacturers at present.
