Description

Technical Field

[0001] The utility model relates to the field of kitchenware, in particular to an inner tank flow guiding device and cleaning equipment. Background Art

[0002] At present, the stainless steel inner tank of the dishwasher is generally connected to the base through biting or welding and gluing, which has a complex production process and high production cost. In addition, these two methods rely on complete sealing, which requires sealing detection, but sealing detection is difficult, resulting in a further increase in the manufacturing cost of the whole machine. However, since the current mainstream cleaning method of dishwashers is spraying, the inner tank cavity of the dishwasher does not need to be completely sealed from the outside world, and the irrationality of the above two methods is more prominent.

[0003] A dishwasher disclosed in a Chinese invention patent with application number 201510084294.5 includes an upper box body, a water collecting tank, a door body and an outer shell that are integrally molded. The door body is installed on an axial hole that cooperates with the water collecting tank through a hinge boss on the door body. A hinge plate that limits the maximum angle between the door body and the washing upper cover when the door is opened is provided on the door hinge shaft, and a gravity balance spring of the door body is provided on the hinge plate; a washing ingredient dispenser support shell is integrally formed on the door body; the upper box body and the water collecting tank cooperate to form a washing box body for accommodating tableware for washing; the air insulation groove on the outer surface of the upper box body, the sealing strip groove, the bowl basket guide rail, and the water softener connection hole are integrally formed with the washing box body, and the hinge body on the water collecting tank cooperates with the door body hinge. This technical solution uses a molding process to produce a split modular module for the dishwasher washing box. The upper box body and the water collection tank are tightly fitted together to form a whole. When the spray arm sprays, the water sprayed to the upper box body flows down along the box wall. The fitting edge line of the main body end face of the upper box body is lower than the fitting edge line of the main body end face of the water collection tank, so that the water flows down along the wall and cannot leak out of the box body. The upper box body and the water collection tank are tightly fitted together to form a whole, which itself has a complex process and also requires sealing detection. Therefore, this technical solution still fails to solve the above technical problems. Utility Model Content
