Benefits of technology
[0010]Therefore, an object of the present invention is to provide a portable refrigerator capable of supplying a sufficient amount of power and capable of being easily carried.
Problems solved by technology
However, the method has disadvantages such as a complicated structure and a large volume.
The method using a thermoelectric element has a lower energy efficiency than the method using a vapor compression type cooling cycle.
However, the conventional portable refrigerator using a battery has the following problems.
Firstly, when a battery of a large capacity is used to supply high power for operating the thermoelectric element, the entire system has a large volume to degrade a portable characteristic.
Secondly, when the battery is consumed up, it takes a lot of time to charge the battery.
