2. Description of the Related Art Heretofore, cold storages having various structures and functions have been developed. For example, Japanese Patent Application No. 4-79980 can be cited. However, the conventional cold-and-refrigerator is provided with a separate inner box for refrigeration and an inner box for warm-up in one main body, and each has a heating means and a cooling means. And, as the cooling means, as is generally used in refrigerators, there are many methods that use gas, chemicals, compressors and the like. A heater is widely used as a heating means.

[0003]

SUMMARY OF THE INVENTION In the conventional refrigerating and refrigerating cabinet as described above, heating and cooling are performed by separate devices to generate hot air or cold air, and the inner box in the cabinet is for refrigerating to refrigerating. It was not possible to switch from hot storage to cold storage. In order to eliminate such inconvenience or uneconomical, it is not necessary to have an inner box for refrigeration and an inner box for hot storage in a single refrigerator, and cooling and heating can be performed with a single device. A storage is desired, and as one of them, the applicant has previously proposed a switchable cold storage.
However, after the examination, from cold storage to hot storage,
Or even if switching from hot storage to cold storage, depending on the purpose of use and the quantity or time condition of the object to be cooled or the object to be heated, it may be necessary to use only refrigeration or hot storage.
It turned out to be inconvenient.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an inner box for storing an object to be cooled or an object to be heated in a refrigerating and refrigerating box, without cooling the box. It is an object of the present invention to provide a method of using a switching type cold / heat storage box in which cooling and heating can be selectively used in various combinations by using a single device for heating and heating.

[0005]

Means and Actions for Solving the Problems
Various means for achieving the above-mentioned object have been studied, and a method has been devised in which four switches are selectively used by switching the switch of the dual-type switchable cold / hot storage to cold or hot.

As a concrete means for achieving the above-mentioned object, the present invention is a double-type cold / hot storage provided with a single cold / hot storage at the top and bottom or the left and right, and in the main body of each cold / hot storage. An inner box for containing the object to be cooled or a heating object is provided, the inner box is provided with a Peltier element, an electronic cooling element composed of a metal body, and a temperature sensor, and a radiation fin is provided through the electronic cooling element, and a switching power supply and a cooling temperature are provided. 2 provided with a changeover switch and a temperature control circuit to which the switching power supply, temperature sensor, cold / hot changeover switch, and electronic cooling element are connected
A method of using the switchable cold / hot warehouse characterized in that the continuous cold / hot warehouse is operated by one combination selected from cold-cold, cold-hot, hot-cold, hot-hot, respectively. It was done.

The cold / heat storage used in the present invention does not need to have an inner box for refrigeration and an inner box for heat storage in one storage, and can be cooled and heated by a single device. The storage is a switchable cold / hot storage that can be used selectively between cold storage and hot storage by switching a switch. Further, the present invention is a double-type cold / hot storage provided at the top and bottom or the left and right, and this cold / hot storage is switched between cold and hot, so that cold-cold,
By using one combination selected from cold-warm, warm-cold, and warm-warm, for example, it is a method of using a switchable cold / warm refrigerator capable of simultaneously preparing a steamed towel or a cold wet towel. .

The electronic cooling element of the switching type refrigerating cabinet used in the present invention is called a "Peltier module", and N-type and P-type semiconductors (Peltier elements) are sandwiched between metal bodies such as plates and blocks. The electronic cooling element is bonded as described above. When a direct current is applied to this P-type semiconductor from an N-type semiconductor to this P-type semiconductor element, the P-type semiconductor in the N-type reverses the direction of the current.
In the shape, heat is transferred in the forward direction, and one metal body is cooled and can take heat from the surroundings. on the other hand,
When the heat on the high temperature side is efficiently dissipated, the heat continuously moves from the low temperature side to the high temperature side. By utilizing such a function of the electronic cooling element, by switching the direction of the flowing current with a switch, it is possible to freely set the cold and hot states in one refrigerator.

If the electronic cooling element having the above-mentioned function is used, a cold storage box composed of one body is provided with an inner box for refrigeration and an inner box for hot storage separately, each of which is equipped with a cooling box. It is not necessary to provide heating means and cooling means. Therefore, the number of parts is smaller than that of a device using a conventional compressor, and the device for cooling, heating, etc. can be made lightweight.

It is preferable that the electronic cooling element of the switchable cold storage used in the present invention has a structure in which the metal body is attached in close contact with an inner box provided in the storage, but the present invention is not limited to this. Provide a container for containing the object to be cooled, etc., attach an electronic cooling element without making it adhere to this container, and have a structure that has a blower for sending cold air or hot air generated by this electronic cooling element into the container You can also

According to the switchable cold / hot refrigerator used in the present invention,
It is not necessary to separately provide an inner box for refrigeration or hot storage in the cold / hot storage, and it is not necessary to provide each heating means and cooling means therein, and since cooling and heating can be used in various combinations, For example, a steamed towel and a cold towel can be prepared at the same time. Then, depending on the purpose of use of the switchable cold / hot storage and the quantitative or temporal condition of the object to be cooled or the object to be heated, it is not simply used in refrigeration or hot storage, but cold-cold, cold-cooled- By operating in a combination selected from hot, hot-cold and hot-hot, it can be used efficiently.
