The evaporator 250 is formed in a spiral shape in appearance, and is provided with a refrigerant inlet through which the refrigerant flows and a refrigerant outlet through which the introduced refrigerant circulates and flows out. The refrigerant inlet is located at the lower center of the evaporator 250, and the capillary rises vertically from the refrigerant inlet, and the cooling tube descends spirally from the upper end of the capillary to form a spiral tube, and the refrigerant outlet is formed at the lower end of the spiral tube. In addition, the refrigerant inlet is connected to the first pipe 251 for introducing the compressed high-pressure low-temperature refrigerant from the compressor, and the refrigerant outlet is coupled to the second pipe 252 for discharging the low-pressure and high-temperature refrigerant to the compressor. A pair of support feet 253 are provided on each of the upper and lower ends of the evaporator 250, and the pair of support feet 253 have a center inserted into and fixed to the fixing rod 220, and an edge of the pair of support feet 253 is inserted into the fixing rod 220 and fixed.

The cooling tube body 260 is formed of a far-infrared ray generating material such as loess soil or charcoal having air permeability, and it is preferable that the inner surface be glazed to block the inflow of moisture from the outside. Therefore, the cooling tube body 260 is made of a material capable of accumulating moisture, but is glazed to block moisture on the inner surface so that moisture is not emitted from the inside to the outside. In addition, since the cooling pipe body 260 is installed on the installation surface 243 of the support plate 250, the cooling pipe body 260 discharges the cold air of the evaporator 250 located inside and the moisture inside the housing 210 is absorb

In addition, the mesh network 270 is installed on the outside of the cooling tube body 260 , but is formed and installed in a cylindrical shape having the same shape as the cooling tube body 260 , and the upper end is when grain is inserted into the housing 210 . , a cover 271 for blocking input grains from flowing into the cooling tube body 260 is formed inside, and the lower end is installed and fixed to the bracket 221 of the fixing rod 220 . Therefore, since the mesh network 270 is installed outside the cooling pipe body 260 , it prevents the grains or input grains fed into the cooling pipe body 260 from coming into contact with the cooling pipe body 260 , so that the grains are frozen or frozen. It prevents damage by cold damage.

In addition, the fixing means 280 is inserted and installed in the first drain hole 233 of the condensation preventing means 230 . The fixing means 280 includes a tube (not shown), and the tube has a first pipe 251 and a second pipe 252 respectively coupled to the refrigerant inlet and the refrigerant outlet of the evaporator 250 to the inside, and condensation A drain pipe 281 for draining water is installed. That is, both ends of the tube are opened, and the first pipe 251 , the second pipe 252 , and the drain pipe 281 are installed therein. At this time, an empty space is formed between the inner circumferential surface of the tube and these pipes 251 , 252 , and 281 , and there is a problem that external air flows into the inside of the cooling tube body 260 through this space. . In order to solve this problem, when the first pipe 251, the second pipe 252, and the drain pipe 281 are installed inside the tube of the fixing means 280, a synthetic resin is filled into the inner space and then hardened by external air to block the path flowing into the cooling tube body 260 . In addition, at this time, various known synthetic resins may be applied as the synthetic resin, but urethane resin or silicone is preferable. In the tube serving as the fixing means 280, the first pipe 251 and the second pipe 252 and the evaporator 250 for introducing and discharging refrigerant from the compressor to the refrigerant inlet and refrigerant outlet of the evaporator 250. A drain pipe 281 for draining the condensed water is inserted together, where the first pipe 251 and the second pipe (251) and the second pipe (252) of the first pipe 251 and the second pipe 252 and the drain pipe 281 ( 252) is inserted into the evaporator 250 in a state already coupled to it, or is coupled to the evaporator 250 in a state in which it is inserted into a tube. Therefore, the first pipe 251, the second pipe 252, and the drain pipe 281 coupled to the evaporator 250 are inserted by the fixing means 280, and the first of the condensation preventing means 230 is inserted. Not only can the drain hole 233 be easily fixed and installed without hassle and complexity, but also the first pipe 251 and the second pipe 252 are buffered during operation to reduce vibration noise by the fixing means 280 . will decrease At this time, the tube is installed on the outside of the first pipe 251, the second pipe 252, and the drain pipe 253 of the fixing means 280 as if it surrounds, when inserted into the first drain hole 233 of the condensation preventing means There is a problem that the tube is torn or worn by external friction. Therefore, by installing the tube body on the outside of the tube of the fixing means 280, the tube is torn or damaged during insertion or disassembly into the first drain hole 233 to solve the problem. In addition, between the inner surface of the tube body 282 and the outer surface of the fixing means 280 is filled with a filler (silicon) that blocks moisture. Therefore, the tube body 282 prevents moisture that may be generated in the fixing means 280 from leaking to the outside due to the temperature difference according to the driving of the first pipe 251 and the second pipe 252, and stored grains to prevent frost damage or damage.

On the other hand, the lower surface of the grain outlet 211 formed in the center of the lowermost portion of the housing 210 is provided with a grain take-out tray 290 for taking out the grain stored inside the housing 210 .

Therefore, the grain take-out receiver 290 can take out the grain stored in the housing 210 as much as desired through the push operation of the discharge hole 291 and the drawer 293 .

The conventional grain refrigerator having such a configuration can reduce the number of work hours compared to the conventional grain refrigerator, and by sealing the inside of the fixing means 280 with a silicone material, it is possible to block external air from flowing into the inside of the cooling tube body 260 . However, there was a problem in that it was not possible to prevent the occurrence of dew condensation occurring on the inside of the mesh network 270 .

When moving a house, power is not supplied to the grain refrigerator for a certain period of time in case of a power outage, and then power is supplied again when the move is completed or the power outage is healed. As such, when power is temporarily not supplied, the mesh network 270 having a small heat capacity has a faster temperature change rate than the cooling tube body 260, so that condensation occurs inside the mesh network 270 when the uninterrupted time is prolonged.
