[0019]
When the cooling air circulating fan 27 is operated while the cooling heat exchanger 26 is operated, the air in the lower part of the refrigerator 20 is sucked into the cold air duct 22 from the cold air suction port 23, and the cooling heat is Cooled by the exchanger 26, the cooled air is blown out to the refrigerator 20 again from the cold air outlet 24 and circulates, and cools the inside of the refrigerator 20 to a predetermined temperature and sets the inside of the refrigerator 20 to a predetermined temperature. The temperature is maintained and the food on the tray is kept cool.
[0020]
A sterilizing means 30 is provided in the hot air duct 11, and an operation of the sterilizing means 30 and an operation of the fan 17 for circulating hot air are provided on the operation display section 2 provided on the upper part of the exterior panel 6. And an electrical opening / closing means 31 such as a switch formed so that an operator can input an on / off state from outside. Then, when the ON information is input to the electric opening / closing means 31, the sterilizing means 30 and the fan 17 for hot air circulation are operated without operating the heat exchanger 16 for heating, and the heat generated by the sterilizing means 30 is generated. The germicidal air is circulated in the storage 10. When the sterilizing means 30 is operated with the partition plate 3 separating the refrigerator 10 and the refrigerator 20 opened, and the fan 17 for circulating hot air is operated, the sterilizing air is discharged into the entire vehicle body 1. Can be circulated.
[0021]
Therefore, even when foods and the like to which bacteria have adhered are stored in the serving car, if the worker operates the electric opening / closing means 31 and inputs information of the operation start after the serving is completed, the vehicle body 1 The inside can be sterilized with sterilizing air, and it becomes a serving truck with excellent antibacterial properties. Further, since sterilization can be performed by selecting a time zone during which the serving truck is not used, sterilization with excellent safety for workers can be performed. Furthermore, since the food can be sterilized after the serving is completed, the food stored in the serving car has little effect, and sterilization with excellent safety for the food can be performed.
[0022]
If the electrical opening / closing means 31 is formed so as to be automatically closed when the open state is continued for a certain period of time, the operator operates the electrical opening / closing means 31 to inform the end of operation. Thus, the sterilization can be completed without inputting the, so that the workability is excellent and preferable.
[0023]
The operation display unit 2 provided on the upper part of the exterior panel 6 controls the operation of the sterilizing means 30 and the operation of the fan 17 for circulating hot air, and controls timekeeping such as a timer capable of setting a desired time. A means 32 is provided, and the sterilizing means 30 is operated for a desired time set in the timekeeping control means 32, and the fan 17 for circulating hot air is operated so that the sterilizing property generated by the sterilizing means 30 is generated. The air is circulated in the storage 10. Therefore, even when food or the like to which bacteria have adhered is stored in the serving car, it operates according to the time set in the timekeeping control means 32 which has set the time period in which the serving is completed in advance, and the inside of the vehicle body Can be sterilized with sterilizing air, and it becomes a serving truck with excellent antibacterial properties. In addition, since sterilization can be performed by selecting a time zone when the serving truck is not used, it is possible to perform sterilization with excellent safety for workers, and it is possible to sterilize after serving is completed, so it is stored in the serving truck. This has little effect on food that is to be sterilized, and sterilization with excellent safety for food becomes possible. Further, even if an operator does not perform a sterilization start operation every day, the processing can be performed every day and the operability is excellent.
[0024]
Note that the sterilizing means 30 is not limited to being provided in the hot air duct 11, and the operation of the cool air circulation fan 27 can be controlled by the electric opening / closing means 31 or the timing control means 32. May be provided in the cold air duct 21, and when both the operation of the hot air circulation fan 17 and the operation of the cold air circulation fan 27 are formed so as to be controllable, May be provided. In addition, it is preferable to provide the inside of the warm air duct 11 or the inside of the cool air duct 21 because the sterilizing air can be reliably circulated throughout the vehicle body.
[0025]
An opening / closing detecting means 33 for detecting the presence or absence of a door provided in an opening on the side surface of the vehicle body 1 is provided near the door, and when the opening is open, the operation of the sterilizing means 30 is stopped. It is preferable that it is formed as follows. In this case, if the door is opened by mistake while germicidal air is circulated in the vehicle body 1, outflow of the germicidal air can be minimized.
[0026]
Ozone is generally used as the sterilizing air, but it is not particularly limited, and any air can be used as long as it has no effect when serving food and can be sterilized. In addition, the sterilizing means 30 is not limited to a device that produces sterilizing air, and may include a gas outlet connected to a gas cylinder that sends out sterilizing air. The amount of sterilizing air generated is appropriately adjusted according to the volume in the vehicle body 1, the processing time, and the like.
[0027]
