Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermostatic device, and more particularly to a thermostatic device useful for transportation of goods which need to be maintained at a constant temperature and for storage outdoors.

[0002]

2. Description of the Related Art As a portable thermostatic device, a small refrigerator / freezer provided with a leisure warming box and a refrigerator is known.

[0003]

However, in the case of transportation of food and medical supplies in the event of a disaster or emergency, and storage outdoors, it is said that the thermostatic device described above has the required functions. I can't say.

That is, it is impossible to maintain a constant temperature for a long time in a heat retention box for leisure because it is not a self-cooling type in the first place.

Further, a small refrigerator-freezer equipped with a refrigerator is suitable for transportation and storage in a low temperature state in summer and the like, but transportation in a high temperature state in winter etc. due to lack of heating function. You can't. further,
When a large amount of material needs to be supplied in the event of a disaster, etc., a large number of thermostatic devices will be transported in a batch while the materials are stored, but in the conventional thermostatic device, if multiple layers are stacked, the balance becomes poor, There was a risk that the load would collapse.

Therefore, an object of the present invention is to provide a technique relating to a portable thermostat having a heating function in addition to a refrigerating / freezing function.

Another object of the present invention is to provide a technique relating to a portable thermostatic device which can be stacked in multiple stages.

The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

[0009]

The typical ones of the inventions disclosed in the present application will be outlined below.

That is, the thermostatic device of the present invention is provided with an upper lid for loading and unloading materials, a main body to which the lid is detachably fixed by a fastener, a handle attached to a side surface of the main body, A heat-insulating box having a cooling means and a heating means installed inside the main body, a generator housed inside, a drive unit housed inside as well, connected to the cooling means and the heating means, and a side surface. And a drive unit attached to the side surface of the heat insulating box.

In this case, an engaging portion is formed on the lid of the heat insulating box and the bottom surface of the main body, and the constant temperature device is vertically engaged with another constant temperature device by the engaging portion. it can.

[0012]

According to the thermostatic device having the above-described structure, since it has a heating function in addition to a freezing and refrigerating function, not only the transportation and storage of materials at a low temperature but also the transportation at a high temperature. Therefore, for example, when the disaster area is cold, it is possible to supply and store warm food.

Further, according to the thermostatic device having the engaging portion formed therein, lateral slippage is prevented when the thermostatic devices are stacked, so that there is no fear of collapse of the load, and a large number of thermostatic devices can be collectively packaged in a state in which materials are stored. It can be transported and a large amount of supplies can be supplied in the event of a disaster.
