The present invention relates to a food container using a thermoelectric element, and more particularly, it is designed to maintain a temperature and freshness of food stored in the container for a long time by making a container capable of cold and warming using a thermoelectric element.

In general, side dishes and foods are stored in refrigerators in a separate food container that can be opened and closed so that side dishes and foods can be kept fresh without being damaged.

As described above, side dishes or foods, which are stored in a food container and stored in a refrigerator, are placed on a table by heating to a proper temperature using this microwave oven or a gas stove.

In general, a refrigerator uses a cooling device consisting of a compressor, a condenser, an expansion valve, and an evaporator that repeatedly compresses and condenses a refrigerant, and releases heat in the storage compartment to the outside to keep the storage chamber at a low temperature.

However, as described above, the conventional food container containing the side dishes and foods has a hassle to store in the refrigerator to maintain freshness, and this refrigerator has a large volume, which is impossible to carry.

In addition, in the case of warm food, there is a hassle to take out the food stored in the refrigerator and warm it again by using a microwave oven or a gas stove, and to eat at a suitable temperature. It was a difficult problem to eat.

In addition, conventional portable thermostats, such as refrigeration appliances such as ice box performs only one function, the volume was a big disadvantage.

An object of the present invention is to provide a food container using a thermoelectric element that can preserve the food freshly by using a heat conduction element that endothermic and heat dissipation by the supply of power to maintain the temperature in the storage room at a suitable temperature for the food to be stored There is.

Another object of the present invention is to provide a food container using a thermoelectric element that can be used to easily store food at home (including restaurants) or outdoors because of its small size and light weight.
