Abstract

PROBLEM TO BE SOLVED: To eliminate the problems that the conventional production of a cooling/heating tank requires much time and effort and cost, resulting in a costly tank and that the properties of some liquid contents do not allow the disposition of a cooling or heating component, etc., in the tank, resulting in difficulty in decreasing a temperature difference between the upper and lower parts of a liquid. SOLUTION: A highly thermal conductive member 3 is attached to the external wall of the tank, from the upper to lower part of the tank. The thermal conductive member 3 is cooled by, for example, a Peltier element, or is cooled or heated by a thermally functioning component 2.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cold storage tank for cooling, heating and storing purified water, tap water, soft drinks, alcohols and the like. 2. Description of the Related Art Conventionally, gas cooling and the like have been mainly used. [0003] However, according to the above-mentioned conventional techniques, cost and labor are required, and an inexpensive tank cannot be obtained. In order to reduce the cost and labor,
A refrigeration tank using a Peltier element that absorbs or generates heat has been proposed, but if refrigerated parts are placed in the tank, substances such as alcohol or substances that easily change in taste are stored. In such a case, it is difficult to put cold and hot parts into the tank because the taste may change. Even if the parts are put inside, cleaning of the inside of the tank or the like tends to be difficult due to the projections and the like, and impurities may easily remain at the projections and corners, so that there is a possibility that bacteria and the like may propagate. Further, there is a problem in reducing the temperature difference between the upper part and the lower part of the liquid. In order to solve the above problems, a heat conductive member 3 having good thermal conductivity is attached from the upper part to the lower part of the outer wall surface of the tank, and the heat conductive member 3 is made of a Peltier element or the like. A cooling / heating storage tank that cools and heats the cooling / heating function part 2 to reduce the temperature difference between the upper and lower parts of the content liquid and efficiently use cold / hot water. FIG. 1 shows an embodiment of the present invention. The heat conducting member 3 is attached to the outer wall surface of the tank, and the heat conducting member 3 is cooled and heated by the cooling / heating function component 2 such as a Peltier element, and the content liquid is cooled and heated from the tank wall surface. Further, since heat is generated on the opposite side of the Peltier element 2, a heat radiating component 4 such as a heat sink and a heat radiating fan 5 are provided to release the heat. Further, the tank is surrounded by an exterior 8, and a heat insulating material 6 such as foamed urethane is inserted between them to insulate the tank. According to this embodiment, since the heat conduction member 3 efficiently cools and heats the tank from the upper part to the lower part of the wall, the temperature of the upper part and the lower part is independent of the amount of the liquid content. The difference is reduced and the outer periphery of the tank is insulated so that cold storage can be performed efficiently. [Other Embodiments] In the embodiment shown in FIG. 1, the upper and lower Peltier elements are arranged one by one. However, in other embodiments, the cooling / heating function part 2 is used in accordance with the manner of cooling and heating the content liquid. It is also possible to change to gas cooling or another thing, or to change the number of cooling and heating functional parts 2 such as Peltier elements. Further, the temperature sensor 9 may be attached so that the setting of the current or the like can be changed by a control plate according to the way of cold storage. Further, the heat conducting member 3 may be changed to a graphite sheet or the like, which is a sheet-like high heat conducting material, to conform to various container shapes. Further, a heat conducting plate 7 having a high heat conductivity may be wound around the tank 1 in order to efficiently transmit heat to the entire tank. Further, the tank 1 may be changed to a container or a tank having a different material and shape. As described above, according to the present invention, even tanks or containers having various shapes and structures can be maintained at a low cost, efficiently and uniformly at a low temperature. Can be used for cold storage. Further, the specification can be easily changed depending on the manner of refrigeration, so that the cost can be reduced. Furthermore, since there is no member inside the tank, impurities are hardly attached and cleaning is easy. Further, by using a Peltier element or the like, failures such as gas leakage and liquid leakage are eliminated. Also, the number of operating parts is reduced, so that failures are reduced. Even if it breaks down, the parts and the like are outside the tank, so only the replacement of the parts and the like is required, and repair is easy. Therefore, a highly reliable product can be made, and it is easy to maintain. [0020]
