Embodiment Construction

[0041] figure 1 A schematic structural diagram of a refrigerator 1 according to an embodiment of the present invention is shown. Such as figure 1 As shown, the refrigerator 1 includes a casing 10, a refrigerator compartment 20, and a freezer compartment 30 (see image 3 and Figure 5 ) and the freezer door 40 for opening or closing the freezer 30. In this embodiment, the freezer door 40 is drawn to open or close the freezer 30, but the technical solution to be protected by the present invention is not limited thereto, and may also be pivotally connected to the box body 10 Thereby, the freezing compartment 30 is opened or closed.

Abstract

The invention provides a refrigerator. The refrigerator comprises a foaming layer, a sealing member, a first elastic member and an external force applying and releasing mechanism, wherein the foaminglayer is arranged between a refrigerating chamber and a freezing chamber, and the foaming layer is provided with a vent hole penetrating through the refrigerating chamber and the freezing chamber; thesealing member is movably arranged in the vent hole; the first elastic member is arranged to release the first elastic force when the sealing member is not subjected to an external force, so that thesealing member moves in the direction of the refrigerating chamber along the vent hole; and the external force applying and releasing mechanism is arranged to apply the external force to the sealingmember when a door body of the freezing chamber is closed to move the sealing member along the vent hole in the freezing chamber direction to an initial position and release the external force when the door body of the freezing chamber is opened to enable the sealing member to be in an unstressed state; and the sealing member is configured to allow air within the refrigerating chamber to flow through the vent hole to the freezing chamber when moving in the direction of the refrigerating chamber along the vent hole, and the vent hole is sealed when the sealing member is moved to the initial position. According to the refrigerator, the air pressure difference between the freezing chamber and the external environment can be reduced, and therefore the door body of the freezing chamber can be easily opened.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a refrigerator. Background technique [0002] During the normal cooling operation of the refrigerator, the air in the freezer shrinks after cooling, and the pressure is lower than the atmospheric pressure of the external environment, which makes it difficult to open the door of the freezer. [0003] In order to solve the above technical problems, an air pressure valve is usually provided through which external air is introduced into the freezer to balance the air pressure difference between the freezer and the external environment. However, this will cause heat loss in the freezer and consume electricity. Contents of the invention [0004] One purpose of the present application is to reduce the air pressure difference between the freezer and the external environment, so that the user can easily open the door of the freezer. [0005] A further object of the present applicati...
