Shape and Structure for Improved Heat Transfer in Kimchi Storage Drawer Room {THE SHAPE AND STRUCTURE OF BRACKET FOR IMPROVING HEAT-DELIVERY AT DRAWER-ROOM IN KIM-CHI STORAGE}

The present invention relates to the shape and structure of the bracket for improving the heat transfer of the kimchi storage drawer chamber, and more specifically to the structure that the evaporation tube is installed on the outer surface of the inner case of the drawer chamber to supply cold air to the kimchi storage drawer chamber. In the above, the bracket shape and structure for improving the heat transfer of the kimchi storage drawer chamber characterized in that the evaporation tube is installed in close contact with the inner case through a bracket consisting of a bending fixing portion and the elastic pressing portion.

In general, a refrigerator is a type of air conditioner, in which a refrigerant compressed at high temperature and high pressure in a compressor is liquefied with a condenser driven by a motor, and the refrigerant condensed at high pressure is transferred to a capillary tube having a small diameter. Vaporizes instantaneously to generate cold air, and supplies the generated cold air into the refrigerator body to keep food stored in the refrigerator fresh. The heat is absorbed by the evaporator, and the vaporized refrigerant is condensed by moving to a condenser through a compressor. Through the above process of releasing heat to the outside as it is liquefied it is continuously performed cooling.

As it is well known, the kimchi storage (or kimchi refrigerator) has been developed recently to allow kimchi to be matured and freshly stored using the principle of the refrigerator only for kimchi. According to the kimchi moderately aged, then maintained at an appropriate temperature is configured to preserve the taste of ripe kimchi for a long time.

Since the kimchi storage is small in size, the general refrigerator is configured to open and close the door to the side, whereas the door is hinged to the upper surface of the body and is configured to be opened and opened to the top. There is a tendency to add a drawer compartment at the bottom.

1 is a view showing the configuration of a typical kimchi storage in cross section and Figure 2 is an exploded perspective view of the installation of the evaporation tube of the conventional drawer chamber.

Looking at the configuration of the conventional kimchi storage, the storage chamber 15 is provided inside the kimchi storage main body 11, the door 12 is opened to open and close to open and close the storage chamber 15, the main body 11 Hinge 13 is coupled to the top of the back.

An upper evaporation tube 16 is installed on the outer surface of the inner case of the storage chamber 15 to supply cold air, and a heat insulating material 14 is placed at a portion requiring heat insulation to increase the heat insulating effect.

A drawer chamber 10 of a drawer type storage method is disposed below the storage chamber 15, and a mechanical chamber in which a compressor 17, a condenser, etc., for a cooling cycle is disposed on a rear side of the drawer chamber 10 is provided. It is partitioned separately.

At this time, the drawer chamber 10 is a structure in which the storage basket for storing the storage and the front plate 19 provided with a handle 18 for opening or closing the storage basket can be integrally coupled. have.

In the structure of the kimchi storage as described above, the metallic heat conductive plate 23 is mediated to the upper and both seating surfaces 21 of the inner case 20 having a flat shape to supply cold air into the drawer chamber 10. The evaporation tube 25 is installed.

When the heat conducting plate 23 is seated on the outside of the inner case 20, the heat conducting plate 23 is inserted into and coupled to the coupling groove 22 formed along the circumference of the upper and both seating surfaces 21.

In addition, the evaporation tube 25 is installed on the outer surface of the heat conduction plate 23 tightly coupled to the upper and both seating surfaces 21 of the inner case 20 as described above, the one made of a cylindrical tube The evaporation tube 25 is formed in a bent shape to be installed while having a wider contact area on the outer surface of the heat conductive plate 23.

At this time, each of the evaporation tube installation protrusions 24 is provided with a pair of protrusions protruding on the outer surface of the heat conducting plate 23 while maintaining the interval of the thickness of the evaporation tube, the ends are bent to face each other It forms a chin.

However, in the conventional configuration as described above, when the evaporation tube 25 is inserted into the evaporation tube installation protrusion 24, a slight separation occurs, so that it is difficult to expect a quick and efficient heat transfer. There is a problem that it is difficult to apply when the shape is changed.

The present invention is devised to solve the above problems, the object of the present invention is to ensure that the evaporator tube is tightly fixed and fixed to the inner case to improve heat transfer, regardless of the shape of the various evaporator brackets applicable It is to provide a bracket shape and structure for improving the heat transfer of the kimchi storage drawer chamber characterized by.
