Description

A liner of refrigerator to be capable of fixing a hot pipe easily

The present invention relates to a refrigerator inside which forms a refrigerator compartment and a freezer compartment in which food is stored, and in particular, it is possible to easily fix a hot pipe mounted to prevent dew from forming on the outside of the door due to the temperature difference between the inside and the outside. It is about the inside of the refrigerator.

In general, a refrigerator is a device for preserving the freshness of food by maintaining the temperature in the refrigerator at a low temperature using the latent heat of evaporation of the refrigerant gas according to the refrigeration cycle of the compressor, the condenser, the expansion valve and the evaporator.

That is, when the compressor compresses the refrigerant gas and raises the pressure and temperature of the refrigerant gas to the saturation pressure, the condenser absorbs the heat of the refrigerant gas of high temperature and high pressure by using water or air to condense and liquefy the refrigerant gas. . The refrigerant gas condensed and liquefied is lowered in temperature and pressure by the throttling action of the expansion valve, and the refrigerant gas is evaporated in the evaporator to absorb heat from the stored food and perform the freezing action.

Figure 3 is a side cross-sectional view showing a typical refrigerator used to preserve the freshness of the food as described above.

As shown in the figure, the refrigerator main body 100 is separated into a freezing chamber 110 for freezing and storing food and a refrigerating chamber 120 for freezing and storing food by the partition 130, the one side of the freezing chamber 110 to be cooled An evaporator 140 that absorbs heat from an object is mounted, and a compressor 150 that is enclosed in a case for soundproofing and dustproofing is installed in the lower part of the refrigerator main body 100.

Meanwhile, the refrigerator main body 100 includes an inner wound 101 of a synthetic resin material forming a freezing compartment 110 and a refrigerating compartment 120 in which food is stored, an outer wound 103 of a steel plate having a predetermined strength, and the inner wound 101. The urethane member 102 is foamed to a space formed between the outer wound 103 to form a heat insulation layer, and the freezing compartment 110 and the refrigerating compartment 120 are opened and closed by the door 160.

As shown in FIG. 4, a flange 104 is formed in the inner box 101 forming the freezing chamber 110 and the refrigerating chamber 120 in which food is stored. As shown in FIG. A hot pipe 105 is installed to prevent dew from forming due to an extreme temperature difference. That is, after the hot pipe 105 is installed on the flange 104, the hot pipe 105 is temporarily fixed with the aluminum tape 106.

In this way, in the state where the hot pipe 105 is temporarily fixed with the aluminum tape 106, the inner phase 101 is bonded to the outer shell 103 of the iron plate, and the urethane portion is formed in the space formed between the inner wound 101 and the outer wound 103. When the member 102 is foamed, the hot pipe 105 is firmly fixed as shown in FIG. 5, and the trauma 103 is in contact with the door 160 due to the temperature difference between the interior and the exterior by the hot pipe 105. Dew condensation in) is avoided.

However, in the case where the hot pipe 104 is temporarily fixed to the flange 104 of the inner box 101 by using the aluminum tape 106 as described above, the product price is increased as additional material costs are added, and also the labor of work. There was a problem that acts as a factor to increase the productivity of the product is increased.

Therefore, the present invention is designed to solve the above problems, it is possible to temporarily fix the hot pipe to the inside without using a separate component, such as aluminum tape, and improve the productivity of the product through the reduction of labor It is an object of the present invention to provide a refrigerator inner box in which the hot pipe is easily fixed.

In order to achieve the above object, the present invention, in the refrigerator inner to form a refrigerator compartment and a freezer compartment in which food is stored, characterized in that the hot groove is inserted into the outer periphery of the flange of the inner phase to form a fixing groove is temporarily fixed do.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in detail.

1 is an exploded perspective view illustrating a coupling relationship between an inner box and a hot pipe of a refrigerator according to the present invention, and a flange 11 is formed in an inner box 10 that forms a freezer compartment and a refrigerating compartment in which food is stored. In the outer circumference of the) is a fixing groove 12 for temporarily fixing the hot pipe 20 is formed.

Therefore, the inner wound 10 is coupled to the outer wound 40 of the steel sheet in a state where the hot pipe 20 bent in a shape corresponding to the inner wound 10 in the fixing groove 12 of the flange 11 is temporarily fixed. And, if the urethane member of the heat insulating material 30 is foamed in the space formed between the inner and outer wound 10 and the outer wound 40, the hot pipe 20 is firmly fixed so as not to flow.

FIG. 2 is a cross-sectional view of a main part of the refrigerator showing a state in which the hot pipes illustrated in FIG. 1 are coupled to each other, and the hot pipes 20 temporarily fixed to the fixing grooves 12 of the inner wounds 10 are heat insulating materials 30. It is firmly fixed to the urethane member so as not to flow by foaming.

When the high temperature refrigerant is circulated through the hot pipe 20 which is firmly fixed in this way, dew formation is formed on the outer box 40 in contact with the door 50 by the temperature difference between the refrigerating chamber or the freezing chamber 60.

As described above, the present invention forms a fixing groove in which a hot pipe is temporarily inserted into a flange outer periphery of an inner box forming a freezer compartment and a refrigerating compartment in which food is stored, without using a separate component such as aluminum tape. The pipe can be fixed to the inside, and the labor for fixing the hot pipe to the inside can be reduced, thereby improving the productivity of the product.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention should be defined only by the scope of the attached utility model registration request.
