``Problems that conventional technology and ideas cannot solve'' Conventional heated serving trucks have a school lunch storage compartment that is sealed with insulation to prevent heat radiation and keep the food warm.
Alternatively, it is known that the school lunch storage room is heated and kept warm using a heat source such as an electric heater installed inside, but in the former case, the school lunch storage room itself is not heated, so the heat radiates internally over time. This has the disadvantage that school lunches are cooled down, and in the latter case, a heat source such as an electric heater is installed, so
The disadvantage is that the structure and handling are complicated and the cost is high.

"Means for solving the problem" This invention aims to solve the above-mentioned conventional problem.
An air inlet and an outlet for blowing out hot air are installed on the heating platform installed at the required locations, and the inlet and outlet are connected to the exhaust outlet and air supply outlet provided on the warming serving truck, and hot air is introduced into the interior. By heating the school lunch storage room through circulation, it is possible to heat the school lunch storage room and store heat before transporting the school meals without installing a heat source in the insulated serving vehicle itself, and after that, the stored school meals can be heated relatively quickly. This paper proposes a heating device for use in a warming distribution vehicle that enables food to be transported and served while being kept warm for a long period of time.
