Description

Small door structure of ice maker

Technical Field

The utility model relates to a household electrical appliances's technical field specifically is an ice maker's wicket structure.

Background

The ice maker is an important component of a high-grade refrigerator, which can provide instant ice blocks and ice crushing services for customers, and the small door of the ice maker of the refrigerator, which is one of important components of the component, plays an important role, because the ice maker is arranged in a refrigerating chamber and the refrigerating chamber, the problem of the ice maker is zero, and the temperature difference is very large when the ice maker is arranged at about 18 degrees below zero, the small door of the ice maker plays a role in sealing the ice making chamber and preventing cold air in the ice making chamber from being conducted to the refrigerating chamber to cause the temperature of the refrigerating chamber to be too low. The importance of the wicket is obvious. In order to achieve a better heat preservation effect, the conventional method in the industry generally uses a chemical reagent for foaming to fill the space inside the small door, but during foaming, a foaming material overflows out of the small door along the gap between the front cover and the rear cover of the small door, so that a considerable number of door bodies are scrapped, and further the manufacturing cost and the difficulty are improved.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an ice maker's wicket structure solves the problem that present foaming material spills over easily.

In order to achieve the above object, the utility model provides a following technical scheme: a small door structure of an ice maker comprises a front cover and a rear cover, wherein the front cover is buckled on the rear cover, a first annular structure and a second annular structure which can be mutually clamped are respectively arranged on the front cover and the rear cover, after the front cover is buckled on the rear cover, the first annular structure and the second annular structure are clamped to form a closed space between the front cover and the rear cover, and foaming materials are filled in the space.

Furthermore, annular structure one be the U-shaped recess, the U-shaped recess includes annular plate one and sets up the annular plate two in annular plate one outside, annular structure two is annular rib, the rib joint is in the U-shaped recess.

Furthermore, the second annular plate is higher than the first annular plate.

Compared with the prior art, the beneficial effects of the utility model are that:

after the front cover is buckled on the rear cover, the annular structure I and the annular structure II are clamped tightly, a closed space is formed between the front cover and the rear cover, and foaming materials are filled in the space, so that the problem that the foaming materials overflow the small door is solved.
