Description

The food and custody device where the Peltier element had built-in}

The present invention relates to a food storage device covering the food, and more particularly, by installing a temperature control device inside the container to keep the inside of the container warm or cold according to the control of the temperature control device to maintain the freshness of the food stored in the container for a long time A food storage device that can be maintained.

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

And, as described above, the side dishes or foods, etc. stored in the refrigerator in the food container are put on the table by heating to a suitable temperature using a microwave oven or a gas stove.

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

When food is stored for a long time, it can be stored in the above-mentioned refrigerator, but when storing food for a short time, there is a problem of wasting energy because cold air inside the refrigerator is discharged to the outside when food is put in or taken out of the refrigerator.

Therefore, when food is stored for a short time, it is most often placed on a table. At this time, a separate cover made of a fiber material is used to prevent food from being contaminated by food.

However, when the cover is used as described above, contamination by foreign matters can be prevented, but no means for maintaining the freshness of the food have been devised. Therefore, a device for maintaining the freshness of the food on the table is urgently required. It is true.

In order to solve the above problems, a conventional food storage device is provided, which includes a container that can cover food, and a cooling pack is installed inside the container to keep food cold, thereby maintaining a food freshness. .

However, such a conventional storage device can keep the food cold because the cooling pack can only maintain the cold temperature, on the contrary, there is a problem that can not keep the food warm. In other words, foods are generally eaten at a proper temperature to help taste and nutrition.

In addition, there is a problem that only the temperature is kept cold only at the site where the cooling pack is installed, and the temperature inside the container cannot be kept cold. That is, since the refrigerant emanating from the cooling pack is not circulated in the inside of the inside of the container, only the cooling pack is kept cold and there is a problem that the entire area in the container cannot be maintained at cold temperature.

And because such a container is made of a single container can block the external temperature for a short time, there is a problem that the internal temperature is dropped by the external temperature over time to maintain the freshness of food.

Therefore, the present invention has the following object to solve the above problems.

An object of the present invention is to prevent food from being contaminated by foreign substances on the table, as well as to control the temperature inside the container by the cold or warm air generated by the control of the temperature control device to store the food at a low temperature state or It is to provide a food storage device capable of temperature control to maintain the freshness of food by keeping it at a high temperature.
