Description

Removable Thermo Container with Heat Supply {a vacuum bottle with heater}

The present invention relates to a mobile thermal insulation container capable of supplying heat, and more particularly, to a mobile thermal insulation container capable of supplying heat configured to maintain a temperature in the thermal insulation container when the temperature difference between the inside and the outside of the thermal container is severe for a long time.

In general, the insulating container is a container made to block the entry of heat to the outside world to maintain the contents stored inside for the purpose of keeping warm or cold for a long time. The inner material of the container is mainly made of double stainless steel, the double wall middle space is vacuum to prevent heat conduction by air, and the inner wall is plated to prevent heat conduction by radiation.

In other words, when the outside temperature is high, the radiation from the outside world is reflected to reduce the absorption of heat. When the outside temperature is low, the radiation from the contents is reflected and returned to the inside to prevent the outside from being emitted in the form of radiation. .

Recently, vacuum manufacturing technology has been developed to produce high vacuum products, but it is true that the quality of vacuum degree is relatively inferior to that of overseas products. In addition, no matter how well the vacuum process of the thermal insulation container, a unique gas is always generated inside the metal itself, so it is difficult to expect perfect thermal insulation power unless there is a special device for removing the gas.

Therefore, the thermal insulation function is degraded when used for a long time in a situation where the temperature difference is severe, there is no device that can increase the temperature of the injected contents.

Accordingly, an object of the present invention is to provide a heat supply containing a plurality of batteries that can maintain the temperature by sensing the temperature in the thermal insulation container to maintain the temperature in the thermal insulation container for a long time in a situation where the temperature difference between the inside and outside of the thermal container is severe The part is provided to be detachable with the body of the thermal insulation container to provide a mobile thermal insulation container capable of supplying heat.
