Description

Low temperature and low moist for rice storage case

The present invention relates to a low-temperature low-humidity rice container, and more particularly, to arrange the heat absorbing plate and the heat sink to remove the humidity due to the temperature difference and the air cooled to the appropriate temperature around the storage case for storing the rice and air circulation It relates to a low-temperature low-humidity rice container by connecting an air circulation fan to maintain a constant temperature and humidity around the storage case at all times.

The quality of rice depends on the ambient temperature and humidity. The optimal storage temperature of rice is 10 ~ 15 ℃ and the environmental humidity is 60 ~ 75%. Maintaining about 13 ~ 15% inhibits the activation of rice and reduces the respiratory function of the rice itself, thereby suppressing the consumption of ingredients that the rice itself has and at the same time prevents mold from occurring.

Therefore, it is important to manage the temperature and humidity in the rice barrel so that the material of the rice can be continuously maintained in a general home or restaurant.

In this regard, as a technology for controlling the temperature and humidity of the conventional rice barrels, domestic patent applications No. 1999-3920 and domestic patent application No. 1999-26787 are equipped with a cooling means in the rice barrels and the rice is stored at a low temperature by the cooling means. A frozen rice container device has been proposed.

First, referring to the technology of the first patent application No. 1999-3920, the technology relates to a rice container for storing rice at low temperature by applying a cooling unit using a thermoelectric semiconductor, through a flow path (pure environment path) formed at the bottom of the rice reservoir. It is a technology that inhales circulating air, cools circulating air in the cooling unit, walks the dehumidifier and the accumulator and sends cold air to the upper end of the rice reservoir through the blower pipe to cool the rice for low temperature storage.

This technology applies the technology that the air cooled by the thermoelectric cooler cools the rice via the inside of the rice. However, this cooling method may cause condensation on the rice. Even after the air dehumidified through the dehumidifier, Condensation occurs on the surface of the rice when the dehumidified low-temperature air flows into the high-humidity rice cellar because high-temperature, high-humidity air is introduced. In addition, a high-performance fan motor is required to circulate the cooling air into the rice bowl, and more energy is required to blow air, thereby reducing energy efficiency of the product.

Looking at the second patent application No. 1999-26787 technology, the technology is installed a thermoelectric element for discharging the heat inside the rice tub to the outside, and the temperature sensor and temperature setter and temperature for sensing the temperature inside the rice tub on one side inside the rice tub Indicators are provided, respectively, and input terminals of the temperature sensor and the temperature setter are connected to the control unit, while the output terminal of the control unit is connected to the thermoelectric element driving unit for controlling the flow of current applied to the thermoelectric element.

This technology is related to the method of cooling the rice by attaching a thermoelectric cooler.If the thermoelectric cooler is attached to the wall of the rice container, condensation problem occurs because the surface temperature of the cooler is low. Because of the heat transfer is made there is a disadvantage that can not evenly cool the stored rice.

The present invention is to solve such a conventional problem, the purpose is to arrange the heat absorbing plate and the heat sink to remove the humidity due to the temperature difference between the air cooled to the appropriate temperature around the storage case for storing rice and air circulation By connecting the air circulation fan to achieve this is to ensure that a constant temperature and humidity around the storage case at all times.
