[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing dew condensation in a brown rice storage, and more particularly to a structure for preventing dew condensation in a brown rice storage that can prevent the occurrence of dew without using any additional equipment.

[0002]

2. Description of the Related Art In the storage of brown rice, a low-temperature storage warehouse is used so that the quality of brown rice is not impaired when a large amount of brown rice is handled.

[0003] In addition, when self-consumed rice is stored by farmers and the like, brown rice is stored in a paper bag or a storage can, stored, milled if necessary, and provided for edible use. However, such storage of brown rice has an adverse effect that the brown rice is at room temperature and the quality of brown rice is likely to deteriorate.

[0004] Therefore, farmers and the like have recently used a brown rice storage in order to store brown rice at a low and constant temperature (10 ° C to 15 ° C) so as not to impair the quality of brown rice.

In this brown rice storage, a wall-side heat insulating material forming a refrigerator compartment is attached to an upper inner surface of the housing, a brown rice storage tank is provided in the refrigerator compartment, and a partition side is provided below the wall heat insulator. A heat insulating material is continuously provided, a machine room is formed in the housing below the partition-side heat insulating material, and a refrigeration unit is provided in the machine room. Is kept at a low temperature, and brown rice is stored in good quality. The refrigeration unit takes in cooling air from outside the housing, and the hot exhaust air from the refrigeration unit is immediately blown out.

[0006]

By the way, in the conventional brown rice storage, the refrigerator compartment and the machine compartment are defined by compartment side heat insulating material. However, if a cold air leaks from the refrigerator compartment, etc. In an environment of high humidity, dew condensation occurs on the lower surface of the compartment-side heat insulating material, that is, one surface on the machine room side. As described above, when dew condensation occurs on the lower surface of the compartment-side heat insulating material, rust is generated, the life of parts is shortened, and dew condensation water enters the storage tank from the shutter portion and deteriorates the quality of brown rice. There was a defect.

Therefore, in order to prevent the occurrence of the dew condensation, when the machine room is provided with a heating heater, a heating element such as a nichrome wire is used as the heating heater. In addition, there is a disadvantage that it cannot be used permanently.

[0008]

Therefore, in order to eliminate the above-mentioned inconvenience, the present invention has a wall-side heat insulating material in which a refrigerator compartment is formed on an upper inner surface of a housing, and brown rice is placed in the refrigerator compartment. A storage tank is provided, a partition-side heat insulator is connected below the wall-side heat insulator to form a machine room below the housing, and a refrigeration unit including a condenser and a compressor is provided in the machine room. In the brown rice storage provided with, an air port is formed in a lower side portion of the housing, and the exhaust air heated by heat exchange by the fan of the condenser is blown out to the center side of the machine room to form the compartment side. The condenser, the fan of the condenser, the compressor, and the rice mill are arranged sequentially from the air port to the center side in the machine room so as to flow to the lower surface side of the heat insulating material.

[0009]

According to the structure of the present invention, when the condenser of the refrigeration unit is driven, outside air is taken in from the air port, and the exhaust air heated by heat exchange with the fan of the condenser. Then, the air passes through the periphery of the compressor and is blown out to the center side of the machine room along the rice mill and flows smoothly to the lower surface side of the partition-side heat insulating material. As a result, the machine room is heated and the lower surface of the compartment-side heat insulating material is also heated, thereby preventing dew condensation from occurring on the lower surface of the compartment-side heat insulating material, thereby improving the quality of brown rice in the storage tank. Maintain good, and
Rice can be satisfactorily polished.
