[0002]

2. Description of the Related Art A conventional cold storage cabinet is a main body and an inner box which is fitted into the main body to form a storage cabinet, and an opening is formed on the upper surface for storing and taking out articles. A container, a door that is pivotally supported by the main body to open and close the storage, and a thermoelectric exchange element (hereinafter referred to as Peltier element) that is formed on one side of the main body and uses the Peltier effect to keep the storage inside cold or hot. ) Is arranged with a heat exchanger part.

In this type of cold and hot storage, the product is kept warm by a desired operating state, that is, a cooling operation or a heating operation, depending on an object to be stored (hereinafter referred to as an item).

[0004]

However, in the conventional cold-and-heat storage, the use has been diversified with the spread of the cold-and-heat storage, and various problems have occurred as follows.

First of all, in the conventional cold storage box, since the inside of the container, which is an inner box, is kept cold or kept warm so that, for example, things that are desired to be cooled well and those that are not desired to be cooled are provided. There was no choice but to keep it cool. Further, in some cases, in the above example, another cold / hot storage was required, and there was a certain limit to the number of items to be stored in one cold / hot storage.

Secondly, when there is an item to be cooled and an item to be heated, it is necessary to prepare separate cold and hot storages. Conventionally, there are cold storages provided with a plurality of Peltier elements, but there is only one inner box and there is no one that can maintain the temperature independently, and if there is an item to be cooled and an item to be heated, one It was not possible to keep warm in the cold storage, and it was impossible to meet these demands in the past.

Thirdly, in the Peltier device, the capacity of only one side is used, for example, only one of the cooling side and the high temperature side is used, and the heat of the other side is wasted to the outside, so that efficient use of electric power is achieved. Didn't.

[0008] Therefore, in order to solve such a problem, it is an object of the present invention to provide a cold storage which can be efficiently used in correspondence with the various diversified uses described above.

At this time, the heat generated on the radiating fin 15 side is taken in from the intake port 20 by the rotation of the cooling fan 19, cooled by the outside air, and then exhausted from the exhaust port 21.

Eventually, the heat conducted to the container chamber 10 of the container 8 spreads and is conducted to the entire container chamber 10 and a part of the heat is conducted to the adjacent container chamber 11. When the amount is small, a considerable temperature difference occurs between the container chamber 10 and the container chamber 11.

For example, when the container 8 is not partitioned by the container partitioning section 9, the temperature of the container 8 is about 10 ° C. in the cooling operation, but when it is partitioned by the container partitioning section 9 as described above, The temperature of the container chamber 11 could be about 14 ° C, while the temperature of 10 was about 3 ° C.

Therefore, one container 8 is provided with a temperature difference in the two spaces formed by partitioning, for example,
If there are items that you want to cool well and items that do not need to be cooled so much, you can store them together in a single cold / heat storage box to keep them cold or keep them warm depending on the temperature of each item.

On the other hand, when the slide plate 13 provided on the container partition 9 is slid, the communication elongated hole 9a and the communication elongated hole 13 are formed.
The amount of cold heat passing through the communication elongated hole 9a and the communication elongated hole 13a from the container chamber 10 to the container chamber 11 is increased or decreased in accordance with the positional relationship with a. Thereby, the container chamber 10 and the container chamber 1
The temperature difference from 1 can be made as desired.
