In general, refrigerators that store products in a refrigerating or cooling state are the most commonly used food storage devices, and are used to keep the storage items fresh while continuously performing a so-called cooling cycle for compressing, condensing, expanding, and evaporating refrigerant. Storage device.

Among such refrigerators, in particular, the kimchi storage is a device that can be installed for a long time to maintain the taste and freshness of the kimchi is installed by the configuration of the heating means for aging the kimchi, and a cooling cycle for maintaining the aged kimchi in a low-temperature refrigerated state.

1 is a perspective view of a conventional kimchi storage.

As shown in the figure, the conventional kimchi storage has a main body 10 having an appearance having first and second storage chambers 21 and 22 for storing kimchi therein, and the first and second storage chambers 21. The first and second storage chambers 21 and 22 are pivotally opened and closed at the upper input openings of the 22 and the first and second doors 24 and 25 hinged to the upper end of the rear surface of the main body 10, respectively. Have

First and second deodorants 27 and 28 are installed on the bottoms of the first and second doors 24 and 25 to remove odors such as kimchi stored in the first and second storage chambers 21 and 22. have.

In addition, first and second gaskets 12 and 13 are installed on lower surfaces of the first and second doors 24 and 25, which contact the upper part of the main body 10, respectively. ) Air is not allowed to escape to the outside.

In the upper part of the front surface of the main body 10, the operation unit 14 is provided with a plurality of buttons (14a) that can be controlled to refrigerated or aged kimchi stored in the first and second storage compartment (21, 22) It is installed.

FIG. 2 is a side cross-sectional view of the kimchi storage shown in FIG. 1, and only a portion of the first storage chamber 21 is shown in FIG. 2.

Of course, although not shown in Figure 2, the second storage compartment 22 is also configured in the same way as the first storage compartment 21.

As shown in FIG. 2, a machine room 30 is provided below the first storage chamber 21 of the main body 10.

In the machine room 30, a compressor 31 driven by an applied power source to compress a low temperature low pressure refrigerant into a high temperature high pressure refrigerant, a condenser 32 for condensing the refrigerant passing through the compressor 31 into a liquid phase; In addition, the control unit 35 is connected to the operation unit 14 to control the driving of the compressor 31 as well as to set the temperature of the first storage chamber 21 to an appropriate temperature.

The outer surface of the first storage chamber 21 absorbs heat in the first storage chamber 21 while evaporating the reduced pressure refrigerant at a low temperature at a low pressure while passing through the condenser 32 and the first capillary tube 48. The 1st evaporation pipe 51 which made the temperature in 1st storage chamber 21 fall is provided.

The heater 16 and the first storage chamber which are not only controlled by the control unit 35 but also heat the first storage chamber 21 according to the operation of the button 14a of the operation unit 14 around the first evaporation pipe 51. A temperature sensor 36 for sensing the temperature in 21 is provided.

The state in which the refrigerant flows in the cooling cycle of the conventional kimchi storage having such a configuration will be described with reference to FIG. 3.

First, when the refrigerant becomes a gaseous state of high temperature / high pressure through the compressor 31, the refrigerant gas flows into the condenser 32 through the discharge pipe 37, and then condenses by being radiated by the cooling fan 33.

The refrigerant condensed in this way passes through the dryer 34 and is divided into first and second branch pipes 41 and 42 to flow.

At this time, the refrigerant flowed into the first and second branch pipes 41 and 42 flows into the first and second solenoid valves 44 and 45 for controlling the circulation amount, respectively, and the first and second solenoid valves ( After the refrigerant having passed through 44 and 45 is brought into a low pressure state by the first and second capillaries 48 and 49, the first and second evaporators disposed outside the first and second storage chambers 21 and 22.

When the coolant flows through the first and second evaporation pipes 51 and 52, the coolant is evaporated by the heat absorbed in the first and second storage chambers 21 and 22 so that a low temperature low pressure gas state is obtained. As a result, the inside of the first and second storage chambers 21 and 22 may be maintained at a low temperature.

Next, the refrigerant gas passing through the first and second evaporation pipes 51 and 52 is combined again in the converging pipe 53 and then re-introduced into the compressor 31 through the suction pipe 39 and the compressor 31. ), The above process is repeated.

By the way, in the kimchi storage which forms a cooling cycle of this type, heat exchange is performed only by the 1st and 2nd evaporation pipes 51 and 52 wound on the outer side of the 1st and 2nd storage chambers 21 and 22, As the refrigerant flows upward from the lower portions of the first and second storage chambers 21 and 22, more cool air is formed at the lower portion than the upper portions of the first and second storage chambers 21 and 22.

In addition to the natural phenomenon (convection) in which warm air moves upward compared to cold air, minute gaps formed in the first and second gaskets 12 and 13 of the first and second doors 24 and 25 are formed. Considering that external air may be introduced through the air, the temperature difference between the upper temperature and the lower temperature in the first and second storage chambers 21 and 22 may inevitably reduce cooling efficiency.

This drawback, after all, may be a cause of over ripening of kimchi, so it is difficult to maintain the taste and freshness of kimchi for a long time in the conventional kimchi storage.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a door evaporation tube for generating cold air to the upper region of the storage compartment of the kimchi storage so that the cold air can be supplied in three dimensions.
