Description

Grain-refrigerator of direct cooling system

The present invention relates to a direct-cooling rice refrigerator for preserving taste by preventing the quality of the rice due to rice worms, bacteria and mold to deteriorate the rice for a long time hygienic, maintaining the moisture content of the rice.

When the rice is stored in a conventional general rice barrel, rice worms are formed or the rice is deteriorated by bacteria and mold. Even in a cold rice barrel, if the cooling method in the refrigerator is an indirect cooling method (fan blowing method), it is contained in the rice. As the moisture is released, the water content of the rice is lowered, which is disadvantageous for long-term storage and also deteriorates the taste.

In the accompanying drawings, Figure 1 is a conventional rice refrigerator configuration diagram, Figure 2 is a side view of FIG.

As shown in FIG. 1, the rice refrigerator includes a machine room 30 at a lower portion of the outer case 10, a rice storage chamber 11 at a top thereof, and a door 20 covering the rice storage chamber 11.

The machine room 30 includes a compressor 31 for compressing a refrigerant, a condenser 33 and a blower 32 for converting the compressed refrigerant into a liquid, and is disposed below the inside of the outer case 10.

In addition, the rice storage chamber 11 has a discharge port 12 is formed so that the cold air comes out on the wall, is stacked with a heat insulating material 13 and is configured in the outer case 10 to the top of the machine room (30).

As shown in FIG. 2, a blower fan 14 for distributing the coolant is positioned behind the discharge port 12 provided in the rice storage chamber 11, and an evaporator tube through which the gas coolant flows is located behind the blower fan 14. (15) is located.

However, such a conventional rice refrigerator has a problem that the inside of the refrigerator is very dry because cold air is supplied into the refrigerator by the blowing fan.

Thus, if rice is stored for a long time, the rice loses its moisture and loses its taste.

As described above, the problem of rapidly decreasing the water content of the rice is caused by the cooling method, and in order to solve this problem, there is a need for a method capable of supplying cold air without using a blower fan.

Accordingly, an object of the present invention is to configure a direct-cooling rice refrigerator that supplies cold air without using a blower fan.

The direct cooling method rice refrigerator for achieving the above object,

It is achieved by forming an inner case surrounding the rice storage chamber, surrounding the evaporation tube to the outside of the inner case, inserting an insulating material between the inner case and the outer case, and forming a plurality of holes in the wall of the rice storage chamber. .

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

Of the accompanying drawings, Figure 3 is a direct cooling method of the rice refrigerator according to the present invention, Figure 4 is a side view of Figure 3, Figure 5 is a perspective view including the internal components and the cooling device according to the present invention.

As shown in Figure 3, the present invention direct cooling method of the rice refrigerator is a part of the configuration as in the prior art, the machine room 130 to the bottom and the rice storage room 120 and the rice storage room 120 to cover the upper portion (110) )

In addition, the machine room 130 also includes a compressor 131, a condenser 132, and a blower 133, and is disposed below the inside of the main body 100 as in the related art.

Here, in the upper portion including the rice storage chamber 120, the application structure of the present invention can be seen, comprising an inner case 121 surrounding the outside of the rice storage chamber 120, of the inner case 121 In contact with the evaporation tube 123 through which the gas refrigerant flows, and surrounds the periphery of the inner case 121 with the heat insulating material 125 including the evaporation tube 123, and then into the outer case 101. Insert the components.

In addition, in the present invention, since there is no blowing fan therein, a plurality of holes 122 are formed in the wall of the rice storage chamber 120 so that cold air flows into the rice storage chamber 120 by causing natural convection. to be.

As shown in FIG. 4, a narrow space is formed between the inner case 121 and the rice storage chamber 120, and condensate generated in the inner case 121 is formed along an inner wall of the inner case 121. It flows down and exits through the condensation hose 134.

In addition, since the foreign matter may be generated between the inner case 121 and the rice storage chamber 120, the water inlet 102 was formed to be cleaned.

As shown in FIG. 5, when the rice storage chamber 120, the inner case 121, and the evaporation tube 123 are taken out and combined with each other, the evaporation tube 123 surrounds the outer wall of the inner case 121. In order to effectively supply the cold air generated from the evaporation tube 123, a plurality of holes 122 are formed in the rice storage chamber 120.

Such a direct cooling method of the rice refrigerator formed a ventilation hole in the rice storage room so that cold air generated from the evaporation tube is diffused into the refrigerator by natural convection, and constitutes an inner case surrounding the rice storage chamber, and evaporates outside of the inner case. It consists of a structure surrounding the tube.

The rice refrigerator configured as described above can maintain the water content of the rice because it does not use a fan in refrigeration of cold air.

In addition, if the evaporation tube is directly wrapped in the rice storage room, the condensed water may be absorbed by the rice, but such a problem may be solved by forming an inner case.

And, by forming a water inlet for cleaning, it was easy to remove the foreign matter generated in the space between the rice storage chamber and the inner case.

As described above, by improving the conventional cooling method using a fan to configure the inner case to the outside of the rice storage chamber, to wrap the evaporation tube on the outside of the inner case, and to form a hole in the rice storage chamber to store the rice by cold storage Quality can be maintained for a long time, and the taste can be preserved by maintaining the moisture content of the rice.
