Description of the invention (2) (Amended in June 88) The central government bureau of the Ministry of Economic Affairs has printed the cooling 10 printed by the consumer cooperative, and has the function of cooling the cooling plate for the storage section 20. That is, since the side wall 40 is made of a metal having a high thermal conductivity, the side wall 40 can be cooled through the cooling unit 10, and the entire housing portion 20 can be cooled. In this way, the rice box device 90 shown in Figs. 7 and 8 cools the temperature in the storage compartment by cooling the metal plate side wall 40 of the receiving portion 20. Contrary to the problem that the previous rice box device has, that is, the cold air from the cooling unit is directly circulated in the storage portion, and only the temperature of the white rice that is directly in contact with the cold air drops sharply. This one rice box device 90 is Since the cooling is performed through the wide-area side wall 40, the white rice stored in the storage section is relatively evenly cooled. In addition, in order to prevent the cold air from directly contacting the white rice, the storage portion 20 is almost sealed by being surrounded by the metal side wall 40. Therefore, the proper humidity of the white rice can be maintained during the cold storage, and the white rice can be stored with good quality. In the rice box device 90, maintaining the internal temperature of the storage portion 20 in a state where the ambient temperature of the white rice is about 20 t or less can prevent the occurrence of pests or mold. On the other hand, in order to prevent low-temperature obstacles such as cracking of the rice or discoloration of the rice due to drying, it is preferable to keep it at about 15 ° C or more. Therefore, for long-term storage of rice, it is desirable to keep the internal temperature of the storage portion 20 at 15 ° C to 20t. For this purpose, it is important to limit the fluctuation (temperature distribution) of the internal temperature of the storage portion 20 to approximately 5 ° C, and the maximum temperature is less than 5 ° C. FIG. 9 (A) shows the temperature of the inside of the rice box apparatus 90. FIG. In FIG. 9 (A), the solid line A indicates the temperature of the central portion of the storage portion 20. The dotted chain line B indicates the temperature of the lower portion B on the back side 2b of the storage unit 20 shown in FIGS. 9 (B) and 9 (C), and the dotted line C indicates the temperature in FIG. 9 (B) and FIG. 9 (C). The temperature of the upper portion C of the front side 2a of the storage portion 20 shown in FIG. From Figure 9 (A), you can know -4-(Please read the notes on the back before filling in this page) -14. R .i— This paper size adopts China National Standard (CNS) A4 specification (210X297 mm) 83. 3.10,000 Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs 499559 A7 _______ 5. Description of the invention (3) According to the invention, when the cooling is started, the part B on the back side 2b is close to the cooling unit 10, so it will be subject to Sufficient cooling caused the temperature to drop sharply, and was saturated at about 14 ° C. On the other hand, because the portion C above the front side 2a is away from the cooling unit 10, the temperature slowly decreases and is saturated at about 20 ° C. The central portion A of the storage portion 20 is slightly similar to the upper portion C of the front side 2a, and the temperature gradually decreases and saturates at about 19t. From these results, it can be known that in the rice box device 90, the internal temperature of the storage portion 20 has a distribution (variation) of about 6 ° C. Although a temperature distribution of approximately 5 ° C can be obtained, it is difficult to determine Ground limit (The storage temperature of the storage unit 20 is within 15 to 2 ° C. Therefore, depending on the use state, environment, etc., the temperature of the storage unit 20 may be partially high or low. Therefore, The rice box device shown in FIG. 7 and FIG. 8 is capable of storing white rice with high quality compared with the conventional cold rice box. However, there is a possibility that the quality of white rice will be lowered and the taste will be damaged. Long-term storage of rice is difficult. Despite such a rice box device 90, if the side wall 40 of the accommodating portion 20 is thickened to a considerable thickness and it is made of a metal plate with excellent thermal conductivity, it is possible to reduce the side wall. The temperature difference of 40 reduces the internal temperature distribution of the accommodating portion 20. However, since this is a side wall material that requires good thermal conductivity of a thick metal plate, the rice box device 90 becomes heavy and the manufacturing cost also increases. As a result, This is not suitable for a rice box refrigerator that can be easily used by farmers or households and can be supplied at a low cost. Therefore, the object of the present invention is to provide a refrigerator that can be used by farmers or families more than the above-mentioned refrigerators.

In addition, it is an object of the present invention to provide a refrigerating device capable of reliably maintaining the temperature in the storage portion within a proper range so that the quality of refrigerated objects such as white rice does not deteriorate. SUMMARY OF THE INVENTION To this end, the present invention The refrigerating device is provided with a circulation part that can circulate air between the storage part and the heat insulation material around the covering storage part provided for cooling, and through this The cooling of the air in the ring portion is performed by using the air as a cooling medium to perform indirect cooling of the storage portion. That is, the refrigerating device of the present invention includes a storage portion that can store white rice or other grains in a slightly closed state; A heat insulation part provided around the side wall of the storage part; a circulation part that can circulate air between the heat insulation part and the storage part; and a cooling unit for cooling the air in the circulation part are the features. The refrigeration unit circulates air (cold air) cooled by a cooling unit between the heat insulation section and the storage section, and the cold air becomes a medium to cool the entire side wall of the storage section from the surrounding. Therefore, the cold air will not be directly blown to the storage section. Refrigerated objects, such as white rice, are still indirectly cooled through the side walls. In addition, by circulating air between the storage portion and the heat insulation portion, not only the side wall facing the cooling unit but also the entire side wall in the other direction is simultaneously cooled. Therefore, it is possible to reduce the temperature difference of the entire side wall forming the storage portion, to allow the entire storage portion to be cooled more uniformly, and to reduce the temperature distribution in the storage portion. Therefore, when refrigerating white rice, etc. in the storage section, it is possible to maintain the temperature change of the storage section within 5 ° C. This is to keep the Chinese paper standard (CNS) A4 (210X 297) (Please read the notes on the back before filling this page) ------- r Order -------- 499559 A7 B7 V. Description of the invention (5) The quality of refrigerated rice is in good condition Best conditions. In addition, in order to cool the accommodating portion, the circulation of conventional refrigerants for cooling, such as halogenated hydrocarbons, is not used, and the circulation of air is still used. Therefore, the circulation portion can be simply constructed without laying pipes or the like. For example, it is sufficient to provide a space for the circulation portion only between the side wall of the storage portion and the heat insulation portion, so that a system capable of reliably cooling the entire side wall can be constructed at a low cost. In addition, unlike the aforementioned refrigeration unit, which is directly connected to the side wall of the storage unit and performs direct cooling, the present invention uses air as a medium, so that the side wall can perform uniform cooling of the storage unit. In this regard, it is also possible to provide a refrigerating device with a small temperature distribution inside the storage section at a low cost, so that a refrigerating device suitable for a rice box device that can be easily used by a family or a farmer can be realized. Therefore, if the refrigerating device of the present invention is commercialized as a cold-resistant rice box, it can keep white rice in a fresh state for a long time, so that it will not cause low-temperature obstacles such as pests or mold, or cause cracking and discoloration of rice, so it can be simple. To obtain white rice with good taste. Moreover, it is possible to provide an inexpensive rice box that can be easily set up and managed by a general household. Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page) as the cooling unit for the air of the cooling and circulation department. It can also use the expansion and compression refrigerant cooling unit, but because the side wall of the storage unit is The air is used as the medium for cooling, so the Peltier cooling unit using the Peltier effect can directly cool the air in the circulation section. If the Peltier unit is used as the refrigerating device of the present invention, a compact refrigerating device capable of cooling the object to be refrigerated over a wide area without using a special refrigerant can be realized with a simple structure. Therefore, it is possible to provide a refrigerating device that can be used safely in the home without having to worry about polluting the environment by releasing the refrigerant.

Description of the invention (6) As the circulation part, although it is also possible to wind the storage part with a highly thermally conductive metal tube that can circulate air, etc. The method is formed, but a refrigeration unit can be simply constructed by providing a space for the circulation portion between the four side walls of the storage portion and the heat insulation portion, and forming a circulation portion by using the space defined by the storage portion and the heat insulation material. Furthermore, a circulation unit that can circulate cold air in a vertical direction along the side wall can be configured. However, it is necessary to provide an air flow path through which the cold air flows in different directions. In contrast, if a fan is provided, the air in the circulation unit can be forcedly circulated horizontally along the outer periphery of the side wall, thereby simplifying the configuration of the circulation unit. In addition, by forcibly circulating the air in the circulation unit by a fan, the circulation efficiency of the air can be improved. Therefore, rapid and uniform cooling of the storage unit becomes possible. In addition, the temperature of the air itself in the circulation unit is equalized by the forced circulation of the air, so there is no case where only the air near the cooling unit is cooled. In addition, since the flow of air increases the thermal conductivity between the cooling unit and the heat transfer surface, it is also possible to improve the cooling efficiency of the cooling unit, so that it is possible to save electricity.

Also, by inserting the spacer from the heat insulation section to support the side wall of the storage section, the proper width of the circulation section can be ensured. Space, the storage unit and the heat insulation unit can be stored in the outer box to simplify the refrigeration device. In addition, by providing a space for the circulation part so as to surround the square side wall, an openable and closable lid can be provided above the storage part, so that it is possible to construct a convenient storage for white rice and other things, especially a rice box and the like which are suitable for storing the things unit. Also, if a high-tightness lid is used to keep the inside of the storage unit, the humidity (moisture) inside can also be kept slightly constant. Therefore, it is possible to provide a refrigerating device, which can prevent the moisture content from the paper standard to apply the Chinese National Standard (CNS) A4 specification (210X297 mm) 499559 Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs A7.

Furthermore, in the rice box device 1 of this example, the heat-absorbing-side heat exchanger 13 of the Peltier cooling device 11 is provided with a flat base 51 and a plurality of fins 52, and most of the fins 52 extend in respective longitudinal directions. It is arranged on the surface of the base 51 in a slightly horizontal direction and arranged in a vertical direction (up and down direction). In addition, the circulation fan 35 is arranged in the horizontal direction of the heat absorption side heat exchanger 13 and the heat absorption heat exchanger 13 in a horizontal direction, so that the air in the circulation unit 30 flows along the longitudinal direction of the fins 52 and is cooled. . Each of the fins 52 is inclined downward in the tip direction, so that the drain water 60 generated by the fins 52 can easily flow to a drain water tray (drain water recovery tray) 61 prepared below. Therefore, no exhaust water remains on the surface of each fin 52, and the heat exchange efficiency can be maintained with high efficiency. In this way, the rice box device 1 of this example is a rice box device capable of cooling the air of the circulation unit 30 with a better efficiency by using the Peltier cooling unit 11 to provide a small, high-efficiency rice box device with low power consumption. In addition, the white rice 70 introduced from the inlet 20b of the storage unit 20 is indirectly cooled through the side walls 21 to 24 like the rice box device described above, and can maintain a temperature range capable of long-term storage while maintaining a moderate humidity. Therefore, it is possible to obtain fresh white rice with good taste from the discharge port 20a of the storage portion 20 at any time. And, because the rice box device 1 of this example is implemented to discharge the water generated inside the device-1 6-This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) (Please read the precautions on the back before (Fill in this page)

Description of the invention (1 5) (Amended in June 88) It evaporates itself and can be released to the outside with dry exhaust gas. Therefore, no piping for drainage water treatment or time labor for drainage water treatment is required. It can be easily set up at home. In addition, since the discharged water is automatically processed, the discharged water does not overflow, or the white rice is wetted back into the storage compartment, thereby deteriorating its quality, and can be used safely. Industrial Applicability: The refrigerating device of the present invention circulates cold air between the storage portion and the heat insulation portion covering the storage portion to keep it cold, so that the storage portion can be evenly cooled, and the size of the storage portion can be kept small. It has a wide temperature distribution and can maintain a moderate humidity, so it can be applied to rice boxes for storing white rice, and not limited to rice, and it can be used to refrigerate and store many other things, such as fresh food, and other refrigerators.
