Description

Refrigerator {REFRIGERATOR}

The present invention relates to a refrigerator having an improved cold-air duct so that the temperature inside the storage compartment can be maintained uniform.

Generally, a refrigerator is a device for storing food freshly provided with a main body including an inner and an outer surface, a storage chamber formed by an inner surface, and a cool air supply device for supplying cool air to the storage chamber.

The temperature of the storage chamber is maintained at a temperature within a certain range required to keep the food fresh.

The storage room of such a refrigerator is provided so that its front surface is opened, and the opened front surface is normally closed by the door to maintain the temperature of the storage room.

Insulation material is foamed between the inner and outer parts to prevent cold air leakage inside the storage room.

Since the foaming of the insulating material proceeds only at a certain temperature or more, heat is generated in the course of foaming the insulating material, and the body has a temperature higher than the normal temperature by about 20 ° C or more in a state where the insulating material is foamed between the inner and outer surfaces.

After the heat insulating material is foamed between the inner and outer surfaces, the temperature of the body is lowered to room temperature, and the heat insulating material is hardened, and the body is subjected to heat shrinkage.

Since the internal contraction is mainly made of a plastic material and the trauma is mainly made of a steel material and the plastic material has a heat shrinkage of about 5 times or more as compared with a steel material, The center portion of both sides of the main body is deformed into a convex shape toward the outside of the main body in the process of lowering the temperature of the main body toward the room temperature, The heat insulating material is hardened in a state where deformation is generated in the shape.

When deformation occurs in the internal and external contours due to the difference in the heat shrinkage between the internal and external contours, the deformation generated in the internal and external contours is reduced by the heat insulator contacting the internal and external contours. In order to increase the volume, the amount of deformation in which the center portion of both side surfaces of the main body is deformed into a convex shape toward the outside of the main body is increased as the thickness of the heat insulating material is decreased as the thickness of the heat insulating material foaming between the inner and outer surfaces is decreased. Even after foaming, the temperature inside the main body of the refrigerator is lowered during operation of the refrigerator, so that the amount of heat shrinkage in the interior is larger, which causes a problem that the deformation amount of the shape increases.

Further, if the thickness of the heat insulating material is reduced, the heat insulating performance may be deteriorated, and the rigidity may be weakened, and the body may be deformed by the weight of the body itself and the load of the material stored in the body.

In order to improve the thermal insulation performance due to reduced thickness of the insulation, a vacuum insulation material is provided between the inner and outer surfaces together with the insulation material. Since the vacuum insulation material is disposed between the inner and outer phases together with the insulation material, , Weakened stiffness can not be compensated.

As shown in Figs. 1 to 3, a heat insulating material 15 foamed between the inner and outer surfaces 11 and 13 of the main body 10 is mainly made of urethane, and the foaming of the heat insulating material 15 It only proceeds above a certain temperature.

Since the foaming of the heat insulating material 15 proceeds only at a predetermined temperature or more, heat is generated in the course of foaming the heat insulating material 15, and the heat insulating material 15 is foamed between the inner and outer surfaces 11 and 13, 10) has a temperature higher than the normal temperature by about 20 ° C or more.

After the heat insulating material 15 is foamed between the inner and outer surfaces 11 and 13, the temperature of the main body 10 is lowered to the normal temperature to harden the heat insulating material 15, and the main body 10 undergoes heat shrinkage .

Since the inner surface 11 is mainly made of a plastic material and the outer surface 13 is mainly made of a steel material and the plastic material has a heat shrinkage amount larger than that of a steel material by about 5 times or more, The central portion of both side surfaces of the main body 10 is deformed into a convex shape toward the outside of the main body 10 in a process in which the inner surface 11 contracts more than the outer surface 13 and the temperature of the main body 10 is lowered to room temperature And in the state where the temperature of the main body 10 is lowered to room temperature, the heat insulating material 15 is hardened in a state where the center portion of both side surfaces of the main body 10 is deformed in a convex shape toward the outside of the main body 10.

When deformation is generated in the inner and outer surfaces 11 and 13 due to the difference in heat shrinkage between the inner and outer surfaces 11 and 13, the deformation generated in the inner and outer surfaces 11 and 13 causes deformation of the inner and outer surfaces 11 and 13, When the thickness of the heat insulating material 15 is reduced, the central portion of both side surfaces of the body 10 is separated from the main body 10 as the thickness of the heat insulating material 15 is reduced. 10, the amount of deformation deformed into a convex shape toward the outside increases, and even after foaming of the heat insulating material 15, the temperature inside the main body 10 is lowered at the time of operation of the refrigerator, The amount of deformation may increase.

Therefore, after the heat insulating material 15 is foamed between the inner and outer surfaces 11 and 13, the temperature of the main body 10 is lowered to room temperature and is generated by the difference in heat shrinkage amount between the inner and outer surfaces 11 and 13 To prevent deformation of the shape, as shown in FIGS. 4 to 5, reinforcement members 100 are provided on both sides of the main body 10.

[ ) And the outer surface (13) without obstacle interference.

The initial discharge position of the heat insulating material 15 foamed in the foam head 810 by the guide pipe 823 is set to a space between the inner and outer surfaces 11 and 13 by the length of the guide pipe 823 in the heat insulating material injection port 29c. Since the initial discharging position of the heat insulating material 15 is extended from the bottom of the rear surface of the main body 10 to the central portion, the obstruction by the obstacle inside the space between the inner and outer surfaces 11 and 13 is minimized, The entire space between the inner and outer phases 11 and 13 can be uniformly filled with the heat insulating material 15 because the high pressure of the heat insulating material 15 is maintained while passing through the inside of the pipe 823. Further, The injection amount can be minimized.

It is also possible to prevent a void phenomenon occurring on the surface of the heat insulating material 15 while the heat insulating material 15 is cured in the space between the inner and outer surfaces 11 and 13 by surface friction during the foaming of the heat insulating material 15 Since the amount of the heat insulating material 15 to be injected can be minimized, the heat insulating material 15 is not exposed to the outside, and the working time can be shortened.
