Description

Easy opening structure of the refrigerator door using the rotating shaft of the handle

The present invention relates to an easy opening structure of a door of a refrigerator, and more particularly, to a refrigerator door using a rotating shaft of a handle so that the door of the refrigerator can be easily opened by a normal force pulled by a person when opening the refrigerator door. It relates to an easy opening structure.

In general, as shown in FIG. 1, the refrigerator is filled with an insulating material such as urethane 15 between a metal cabinet 14 forming an external mold and an inner box 16 made of a plastic injection product. (17) is formed. The storage space 17 serves as, for example, a freezer compartment or a refrigerating compartment, and although not shown, the low temperature is maintained by a compressor, a refrigerant cycle, or the like of the machine room 18.

Typically, the refrigerator 10 has a door 12 that can be rotated by a hinge or the like to open and close the storage space 17, and a handle 13 is installed in the door 12. The door 12 and the cabinet 14 are in contact with a sealing member such as a gasket 11 which is a means for sealing in order to prevent cold air such as a freezer compartment or a refrigerating chamber from leaking out.

When the user using the refrigerator 10 wants to store or withdraw the stored object such as food or the like into the storage space 17, the door 12 is opened by pulling the handle 13.

However, according to the structure of the door 12 of the conventional refrigerator 10, in the case of a direct-cooling refrigerator or a freezer, when the temperature in the storage space 17 and the outside temperature become, for example, about -40 ° C, it is common. There is a problem that the door 12 is not opened even by the force pulled by an adult, for example, about 20 kg.

When the door such as a freezer is opened, cold air in the storage space 17 and hot air outside are mixed with natural convection. In this state, when the door of the freezer is closed, the mixed hot air in the storage space 17 is cooled. The volume is reduced, and accordingly, the air pressure in the storage space 17 is lower than the external air pressure, so that the door 12 is subjected to the force of the air pressure difference, thereby making the closed state more firm.

By the way, according to the structure of the handle 13 attached to the conventional door 12, when the user pulls the handle 13, the door 12 is pulled as a whole, by the handle 13 There is a problem that the force is difficult to open the door 12 because the force is distributed throughout the door 12.

Therefore, the present invention has been invented to solve the above problems, using a rotating shaft of the handle so that it can be easily opened by the force applied by the ordinary user when opening the door 12 of the refrigerator 10 The purpose is to provide an easy opening structure of the refrigerator door.
