Description

Easy opening structure of the freezer door.

The present invention relates to an easy opening structure of the freezer door, and more particularly, to an easy opening structure of the freezer door for improving the structure of the freezer handle so that the door opening of the freezer can be easily performed.

In general, the freezer 100 compresses saturated steam of a low boiling point refrigerant having a low heat source as an inside of the freezer 100 and a high heat source to a high pressure in a compressor (not shown) to condense (not shown). In the condenser, latent heat of evaporation is released from the high-pressure and high-temperature refrigerant to the high-heat source outside the freezer, causing a phase change to a liquid-phase refrigerant. After that, it is introduced into an evaporator, that is, a cooler (not shown). The low-pressure and low-temperature refrigerant in the cooler absorbs latent heat from the low heat source inside the freezer 100 in a liquid phase to cause a phase change to a saturated steam refrigerant, and then flows into the compressor described above to resume the circulation cycle of the refrigerant. Will be constructed.

In addition, the freezer 100 as described above is a door 112 to open and close the storage space in the front of the body 111 of the freezer 100, as shown in perspective view in FIG. ) Is installed, and a handle 10 is installed at a predetermined portion of the door 112 to easily open the door 112. Accordingly, while storing and withdrawing the object to be stored in the storage space of the freezer 100, the cold air inside the freezer 100 is prevented from leaking to the outside.

In this case, a gasket 113 is installed at a contact portion with the cabinet of the main body 111 of the door 112 so that the cold air inside the freezer 100 is not leaked to the outside, and a magnet ( Not shown) is installed.

Therefore, when the door 112 is closed, the door 112 is attracted to the main body by the magnetic force of the magnet installed in the gasket 113, and the main body 111 of the freezer 100 is in contact with the cabinet. While maintaining the closed state of the door 112, the cold air inside the freezer 100 is prevented from leaking to the outside.

However, according to the configuration and operation of such a conventional freezer door, when the user opens and closes the door 112 several times in a short time in a short time, the outside air of a relatively high temperature compared to the internal temperature of the freezer 100 Is penetrated into the freezer 100, a momentary pressure difference is generated in the freezer 100, and the suction force of the door 112 being attracted to the main body 111 is increased by the pressure difference. When the door 112 is opened, the door 112 is not easily opened, and a problem occurs such that the main body 111 comes to the door 112 in the freezer 100.

Therefore, the present invention has been invented to solve the above problems, and solves the difficulty of opening the door 112, which occurs due to the instantaneous pressure difference inside the freezer 100 when the door 112 is opened. The purpose is to provide an easy opening structure of the freezer door so that the opening of the door 112 can be easily performed.
