Description

Refrigerator {Refrigerator}

The present invention relates to a refrigerator. More particularly, the present invention relates to a refrigerator including a detachable refrigerator that is removable from a main body refrigerator.

A refrigerator is an appliance that can be used to refrigerate or refrigerate food using a cooling cycle. Therefore, the refrigerator is not installed in a place where electricity can not be supplied.

Generally, a refrigerator is not frequently moved once it is installed. Refrigerators are relatively bulky and heavy among electronic products. That is, it is not easy to move a refrigerator already installed in a place where the refrigerator is not installed.

As a result, it is not easy to store food in a place where electricity can not be supplied or in a place where a refrigerator is not installed, although it can be supplied with electricity.

An icebox is almost the only means available to refrigerate or freeze food in places where it can not receive such electricity or where there is no refrigerator. Here, the ice box refers to a product that can store food stored in an enclosed space in a frozen / refrigerated state by using cold stored in a cold storage medium.

However, in order to utilize the ice box, the user must buy the ice box separately. In addition, in order to use the ice box, it is necessary to supply cool air to the cooling material beforehand.

Therefore, in a place where no electricity can be supplied or in a place where a refrigerator is not installed, a means for refrigerating or freezing food without utilizing an ice box is required
