Description

Supporter hinge structure using refrigerator

The present invention relates to a refrigerator, and more particularly, to an inner case of a refrigerator compartment or a freezer, in which a support length of a door hinge fixed to one side of a barrier part, which is a partition wall that divides the refrigerator door from one side of the refrigerator into a refrigerator compartment and a freezer compartment, can be rotated. A refrigerator supporter hinge structure which extends to an end portion and prevents deformation and damage of the door hinge and sag of the refrigerator door itself from the weight of the door acting on the door hinge and the load of the beverage stored in the door basket. It is about.

In general, the refrigerator discharges cold air generated by a refrigeration cycle composed of a compressor, a condenser, an expansion valve, an evaporator, and lowers the temperature in the refrigerator to freeze or refrigerate food and the like. As shown in FIG. 1, the main body 100, a freezing chamber 110 and a refrigerating chamber 120 for freezing and refrigerating loads (food) by dividing up and down inside the main body 100, and the main body 100. The refrigerator compartment door 130 and the refrigerator compartment door 140, which are mounted at one side of the refrigerator, to open and close the freezer compartment 110 and the refrigerating compartment 120, and cold air necessary for cooling the freezer compartment 110 and the refrigerating compartment 120 may be generated. It consists of a refrigeration cycle equipment consisting of a compressor 150 and a condenser (not shown), an expansion valve (not shown), and an evaporator 160 forming a refrigeration cycle.

In addition, the cold air generated through the evaporator 160 to take the ambient heat of the elements of the refrigeration cycle equipment to evaporate the refrigerant in the gas phase state to each shelf 170 of the freezer compartment 110 and the refrigerating compartment 120. Cold air discharge ports 190 and 190a are formed in the inner wall (grill) 180 of the rear surface of the freezing chamber 110 and the refrigerating chamber 120 so as to be discharged.

In the refrigerator configured as described above, the refrigerant, which is phase-changed in a low temperature low pressure gas phase by the evaporator 160, flows to the compressor 150 and is compressed from the low temperature low pressure to the high temperature high pressure through the compressor 150, and the compressed high temperature high pressure The gas phase refrigerant is cooled and condensed in the course of passing through the condenser, and is phase-changed to a high-pressure liquid state. The refrigerant, which has been phase-changed into a high-pressure liquid state, is easily evaporated by heat exchange in the evaporator 160 while passing through an expansion valve. After decompression (heat expansion), the refrigerant flows to the evaporator 160 where the evaporation process is performed. As described above, the refrigerant introduced into the evaporator 160 absorbs heat inside the refrigerator and absorbs heat inside the refrigerator. After the phase change to the state to cool the air around it, it forms a refrigeration cycle flowing back into the compressor 150.

At this time, the air (cold air) cooled while losing heat to the refrigerant through heat exchange with the evaporator 160 is driven by the blower fan 200 installed on the evaporator 160, the freezing chamber 110 and the refrigerating chamber 120 The temperature of the freezer compartment 110 and the refrigerating compartment 120 is lowered as the discharge air is circulated through the cold air discharge ports 190 and 190a formed on the rear inner wall 180.

It is fastened to the support is fixed to one side of the barrier unit 220. Reference numeral 230 is a barrier cover 230.

However, in the case of the supporter hinge 240, the fixed length inside the barrier unit 220 does not extend to the ends of the inner cases 112 and 122 of the freezing compartment 110 or the refrigerating compartment 120. Since the length of the freezer compartment 110 or the refrigerating compartment 120 of the inner case 112, 122 of the freezer compartment 120 is formed only to a position separated by a predetermined length, the door hinge 250, the weight of the door 140 and the door basket ( When the load of the beverage is stored in the (not shown), the weight of the door 140 and the beverage is not the inner portion 112, 122 of the barrier unit 220 and the freezer compartment 110 or the refrigerator compartment 120 The door hinge 250 is deformed due to the weight of the water in the door 140 and the water stored in the door basket as the door hinge 250 is supported only by a part of the fixed barrier part 220 through the supporter hinge 240. There was a big problem of being broken or broken.

In addition, the door 140 deflection occurs due to the weight of the door 140 and the load of the beverage stored in the door basket, which causes the refrigerator 140 to sag downward, thereby preventing the refrigerator compartment from being sealed. There was also a big problem.

In order to solve the above problems, the present invention provides a support length of a door hinge fixed to one side of a barrier part, which is a partition wall that divides the refrigerator door from one side of the refrigerator into a refrigerator compartment and a freezer compartment so that the refrigerator door can rotate. The purpose of the present invention is to prevent deformation and breakage of the door hinge from the weight of the door and the weight of the beverage stored in the door basket acting on the door hinge by extending to the inner case end.

In addition, the door itself due to the load action of the weight of the door and the beverage contained in the door basket is another object to be able to prevent the door sag down.
