Description

Portable Heating Device

The present invention relates to a portable heating device, and more particularly to a portable heating device with a built-in electrical heating means as a heat supplement device is stored and transported with the food for the continuous insulation of the food during transport or waiting to supply.

In general, the supply of food applied to the event is greatly limited by the separation of physical space.

This is very different from the food supply in restaurants, especially since most foods are heat cooked.

For example, in the provision of liquid foods such as soups, on-site cooking is subject to time and equipment constraints, and therefore is completed at a food production site where space and equipment are provided, and then packaged and delivered to a transport container.

At this time, the food is cooled in the transfer process, because it is difficult to maintain a sufficient warmth even if the large cooking vessel itself is shared as a transport storage container, or even using a warm storage container.

For this reason, it is necessary to keep warming means for preventing the temperature drop of cooked food during the transfer process or the storage process before feeding.

Insulating means is divided into using the heat storage container, and to compensate for the loss heat, the heat storage container is generally used to store the food cooked in a box made of a heat insulating material such as styrofoam material through a separate container.

In addition, to compensate for the loss of heat to maintain a large heat storage container by heating a large storage vessel, for example, a gas stove, where the storage container is common to the common cooking vessel.

However, such a thermal insulation means has a problem that its use is inconvenient.

The use of the heat insulation box prevents heat loss to some extent, but cannot ensure sufficient heat insulation, and thus requires a separate heating device, which makes the supply of cooked food inconvenient.

In addition, the use of a large cooking vessel is also necessary to provide a separate heating device at all times, so that the supply is inconvenient in the same context as described above.

Of course, in order to compensate for the heat and the lost heat of the heat cooked food, a storage container with a built-in heating apparatus is performed or designed.

For example, the portable thermal insulation lunch box (Application No. 20-2002-0022896) is a portable thermal insulation lunch box to heat the internal food using a heating element that generates heat by a charged power source as shown in Figure 1, The switching circuit unit for setting the heating state, the temperature sensing unit for sensing the temperature of the inner container of the Bowon lunch box, and comparing the value input from the lamp and the temperature sensing unit set by the switching circuit unit to control the warming and heating state And a heat generation control section including a temperature control circuit section and an output driver for turning on / off the heating element by a signal of the temperature control circuit section.

However, this is for personal use. For example, it is difficult to separately manufacture a storage container for 30 servings or a storage container for 10 servings, and thus, there is no practical benefit as a general-purpose device according to food supply, and a mold for placing such a heating device for each container. The addition of parts or components creates a difficulty in securing productivity, especially when considering the use in a cooking company rather than a personal consumable.

The present invention has been made to improve the above problems, to provide a portable heating device that can be put into the food storage container as a heat supplement means for covering the lost heat to keep the food inside the container for storing food. The purpose is to.
