Description

Assembly structure of evaporation pipe for kimchi-refrigerator of drawers}

The present invention relates to the evaporation tube installation structure of the drawer type kimchi storage to reduce the manufacturing cost, improve assembly and increase the heat transfer effect.

In general, frozen foods and refrigerated foods or fermented foods such as kimchi should be stored at a moderately low temperature for long-term storage and storage. For this purpose, refrigerators have been used, and recently, only refrigerators for kimchi have been developed and widely used.

The inside of the kimchi storage is equipped with a cooling device and a heating device. Initially, the kimchi is matured by using a heating device, and then the temperature of the storage container is maintained at an appropriate level by using the cooling device, thereby the taste and freshness of the kimchi. Long-term preservation.

In the accompanying drawings, Figure 1 is a cross-sectional view showing the configuration of a general drawer type kimchi storage, Figure 2a is a perspective view of the inner case is installed a conventional evaporation tube, Figure 2b is a cross-sectional view taken along line A-A '.

As shown in FIG. 1, the conventional drawer type kimchi storage box includes an outer case 10 having a box shape, an upper storage chamber 21 and a lower storage chamber 22 formed to have a door opening at the front of the outer case 10. The door 30 is opened and closed while sliding the storage compartments 21 and 22, and the machine compartment 40 is disposed at the rear and bottom of the outer case 10.

In addition, the front upper end of the outer case 10 is provided with a control unit 50 for the operation of the device, the cooling device installed in the machine room 40 is a storage container using the endothermic action generated when the compressed refrigerant is expanded. By keeping the temperature inside constant and suppressing premature ripening of kimchi, it is composed of a compressor, a condenser and a blower, and is connected to the evaporation tube 60 surrounding the outside of the storage chambers 21 and 22.

Here, the operation of the kimchi storage, when the compressor is operated, the refrigerant is compressed to a high temperature and high pressure is sent to the condenser, the refrigerant moved into the condenser is converted to a liquid state in the process of heat exchange with the air sucked by the blower The liquid phase refrigerant is converted into a gas of low temperature and low pressure while passing through the expansion valve.

The low-temperature and low-pressure gas passes through the evaporation tube 60 and absorbs heat from the inner storage chambers 21 and 22. In this process, the air in the storage chambers 21 and 22 is cooled to maintain a low temperature state. It becomes possible.

As shown in Figure 2a, the drawer chamber of the drawer type kimchi storage is composed of an inner case 23, and the storage chamber (21, 22) coupled to the inside of the inner case (23).

The outer circumferential surface of the inner case 23 is surrounded by a metallic plate 24 having excellent thermal conductivity, and the evaporation tube 60 is surrounded by the outside of the plate 24.

The evaporation tube 60 is composed of a cylindrical tube, is bent, the evaporation tube 60, the plate 24 and the inner case 23 is closely coupled by a bracket (25). .

That is, a plurality of first screw holes 23a are formed on both side surfaces and the upper surface of the inner case 23, and the plate 24 has a second screw hole corresponding to the first screw hole 23a ( 24a), a third screw hole 25a corresponding to the first and second screw holes 23a and 24a is formed in the bracket 25, and the evaporation tube 60 and the plate 24 are formed. And the inner case 23 are brought into close contact with each other, and the three screw holes 23a, 24a, and 25a are overlapped into one, and the screws 26 are fastened to each other.

As shown in Figure 2b, the bracket 25 is composed of a bent fixing portion formed to surround the evaporation tube 60 and a thick portion formed with a third screw hole (25a), the screw hole (25a) The screw 26 is engaged.

However, the evaporation tube installation structure formed in this way has a hassle to manufacture the bracket separately because the evaporation tube is combined by using a bracket, and thus requires a manufacturing cost, and is complicated when assembling by screwing, If the shape or spacing is changed, there is a problem that the bracket must be manufactured again.

In addition, when the bracket is molded of a synthetic resin or the like, the conduction effect is inferior, if such a bracket surrounds the outer surface of the evaporator tube is also inferior in heat transfer effect.

As described above, the manufacturing cost is high and the problem of inferior assembly is a factor in the coupling of the evaporator tube by using a bracket and a screw. It is necessary to devise a structure that can.

Therefore, an object of the present invention is to provide an evaporation tube installation structure that can be formed by bending the plate directly to the inner case and the plate close to the evaporation tube, to reduce the manufacturing cost and improve the assembly.

Evaporation tube installation structure of the drawer type kimchi storage to achieve the above object,

In close contact with the inner plate constituting the drawer chamber and the evaporation tube for transferring cold air and the metallic plate with excellent thermal conductivity, it is achieved by cutting a portion of the plate and bending to wrap the evaporation tube and close to the inner case. .

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

In the accompanying drawings, Figure 3a is a perspective view of the inner case is installed evaporation tube according to the present invention, Figure 3b is a sectional view taken along line AA 'of Figure 3a.

Since the configuration of the drawer kimchi storage is the same as the conventional, the description is omitted, and the overlapping doban was used.

As shown in FIG. 3A, when the inner case 23 constituting the drawer chamber of the drawer type kimchi storage is separated and examined separately, a metallic plate 24 having excellent thermal conductivity surrounds the outer circumferential surface of the inner case 23, and the plate ( The evaporation tube 60 surrounds the outside of 24.

The evaporation tube 60 is to transfer cold air to the inner case 23 via the plate 24, the evaporation tube 60 made of a cylindrical tube on the outer surface of the plate 24 It has a bent shape to be installed with a wider contact area at.

In addition, the plate 24 is in close contact with the inner case 23 to receive heat more effectively from the evaporation tube 60. For this purpose, the present invention cuts and bends a portion of the plate 24 to While pressing and wrapping the evaporation tube 60 is tightly coupled to the inner case (23).

That is, the plate 24 is installed in close contact with both side surfaces and the upper surface of the inner case 23, the evaporator tube 60 is disposed on the outer circumferential surface of the plate 24, and then the plate 24 is partially mounted. It is cut and wrapped to wrap in close contact with the inner case 23 while wrapping the evaporation tube 60.

As shown in FIG. 3B, the plate 24 is tightly coupled to the outer surface of the inner case 23, and the evaporation tube 60 is disposed on the outer surface of the plate 24. It is bent along the shape of the evaporation tube (60) surrounds the evaporation tube (60).

Unlike the related art, since the outer circumferential surface of the evaporation tube 60 is more exposed to air, cold air is more effectively transmitted to the inner case 23.

In addition, even if a portion of the evaporation tube 60 is wrapped by the plate 24, the plate 24 is excellent in thermal conductivity, so that the evaporation tube 60 is exposed to the outside air. There is no difference in cold air delivered to the inner case 23.

In this way, in close contact with the plate and the evaporation tube in the inner case, by directly bending the plate without using a separate device to secure the evaporation tube in close contact to reduce the manufacturing cost, the plate with excellent thermal conductivity is wrapped by a separate bracket, etc. Since it does not exist, the heat transfer effect from the evaporation tube is also increased.

As described above, by bending the plate wrapped around the evaporation tube and crimped to the inner case, there is no need for a separate device to reduce the manufacturing cost, and because the evaporation tube is not wrapped with a separate bracket, the heat transfer effect is also increased, Even if the shape or spacing of the evaporation tube is changed, the plate can be bent and bent after installation of the evaporation tube to facilitate the work.
