Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a school lunch storage storage vehicle.

[Conventional technology]

In recent years, it has become necessary to keep school lunches cooked at school lunch centers warm while transporting them to schools and hospitals, and between the time they are transported and before lunch time. There is a known device, such as the thermostat described in Publication No. 38185, in which an electric heater is buried in the bottom and the lower half of the side wall, an opening/closing door is provided, and a shelf is mounted on a locking piece on the inside wall of the refrigerator. be. In addition, like the food and drink storage thermal storage storage described in Japanese Utility Model Application No. 62-101442, a U-shaped heat pipe panel is installed inside the storage storage, an electric heater and a heat storage device are installed at the bottom, and the heat pipe panel A device is known in which a tray is supported on a supporting shelf piece inside the tray. Further, there is a known device, such as a heated lunch box described in Japanese Patent Application Laid-Open No. 53-102167, in which a lunch container, a heater, and a rechargeable battery are provided in an outer case. In addition, like the heater described in Japanese Utility Model Application Publication No. 58-179053, a heating element is provided on the upper outer periphery of a bottomed cylindrical storage container, a vacuum double container is provided on the outside of the heating element, and a heat insulating material is provided on the outside of the heating element. There is a known device in which the device is covered with a gasket, surrounded by an outer frame, and a lid is provided at the upper opening.

[Problem to be solved by the invention]

Each of the above-mentioned devices does not have a heater installed all around the container, so it is not possible to uniformly heat and keep the entire area inside the container. Even if you try to transport the food to a school or hospital by loading it onto a car, etc., it is not configured to be able to transport food by loading it onto a car, and the car does not have a power source for heating, so it may cool down during transport. It is not possible to maintain good heat retention.

For this reason, assuming that the car is equipped with a heating source,
The heat-insulating warehouse is equipped with multiple food storage rooms equipped with heat-exchange steam pipes and humidifying steam pipes to which heated steam is supplied via steam air pipes. A liquid heating boiler that ignites and burns supplied gas and a steam reservoir are mounted on a vehicle, and the heated steam generated in the steam reservoir by combustion of the gas is used to heat, keep warm, and humidify the food storage compartment. A car is known from Japanese Utility Model Application Publication No. 52-97719.

However, these hot food delivery vehicles not only keep the food warm, but also maintain the humidity of the food, so they must use heated steam, which requires a gas-fired boiler and a steam reservoir, which generates heat. The vehicle must be equipped with heated steam piping, heat exchange steam pipes, and humidification steam pipes.
There is a problem in that not only the equipment onboard the vehicle is large and expensive, but also special measures must be taken to carry and handle the dangerous flammable gas on board.

Furthermore, since heat retention and humidification are performed using heated steam, there is a problem in that it is difficult to control the heat retention temperature to maintain an optimum heat retention temperature.

The present invention eliminates the use of dangerous substances as described above, does not require special measures for handling them, improves the drawbacks of being large and expensive, and can easily maintain an optimal temperature. To provide a storage transport vehicle for transporting school meals which can transport school meals in good condition and keep them warm.

[Means to solve the problem]

In order to achieve the above-mentioned object, the storage truck for transporting school meals of the present invention is provided with a heat insulating material 3 and a heat-retaining electric heater 4 between the double walls of the box body 2, and a door 7 loaded with a heat insulating material. A plurality of bars 6a and 6b are provided on the front surface and hold the school lunch container 20 horizontally on opposing inner surfaces.
are vertically spaced apart from each other, a power supply connection portion 5 is provided on the outer wall surface, and the height including the lid body 21 is set to the crosspieces 6a, 6.
The school lunch container 20 whose vertical spacing is equal to or less than b is attached to the crosspiece 6.
The storage 1 for transporting school meals supported by A and 6B is loaded onto the container 31 of the school lunch transport vehicle 30, and the power supply line 34 of the generator 33 mounted on the container 31 is connected to the power supply connection part 5 of the storage 1. It is connected.

[Effect]

A school lunch container 20 is stored in the school lunch transportation storage 1. The power supply line 34 of the generator 33 mounted in the container 31 of the school lunch transport vehicle 30 is connected to the school lunch transport storage 1.
The inside of the storage 1 is heated and kept warm by connecting it to the power supply connection part 5 provided in the storage compartment 1 and energizing the heat-retaining electric heater 4 from the generator 33 to generate heat.

Since the heat-retaining electric heater 4 is electrically heated by being energized, it is easy to control the temperature to be kept constant, and the heat-retaining electric heater 4 is energized by generating electricity from a generator 33 mounted on the transport vehicle. Unlike the conventional gas combustion equipment that generates heating steam to heat the equipment, there is no need to take special measures to transport or handle dangerous combustible gas, and it is safe and easy to handle, and it is effective for power generation. Safety is ensured by installing the machine 33 inside the container 31 of the transport vehicle.

In addition, by providing the heat-retaining electric heater 4 between all the double walls of the box body 2, the entire area inside the storage 1 is evenly heated and kept warm. By providing this, heat dissipation inside the storage 1 is uniformly prevented over the entire area inside the storage, and the temperature is maintained at a constant temperature.

The school lunch containers 20 are stored in the school lunch transport storage 1 and loaded one after another onto the shelves 32 in the container 31 of the school lunch transport vehicle 30, and the generator 3 is installed inside the container 31.
The power supply line 34 of No. 3 is connected to the power supply connection part 5 provided in the food storage storage 1, and the electric heater 4 is energized by the generator 33 to heat the inside of the storage storage and keep the school food warm. Transport the prepared school food to the demand destination. After transportation, by connecting a household power source to the power supply connection part 5 provided in the storage 1, the school lunch can be kept warm until the time of school lunch.
