The power supply device 85 is electrically connected to a commercial power supply 90 which is a power supply unit via a main power supply line 88 and a timer unit control power supply line 89.

  One power supply device 85 installed at the provider is electrically connected to the three container devices 1 via the power supply line 81 when the food can a and tableware b are heated and disinfected at the provider. Electric power from commercial power supply 90 is supplied to the three connected container devices 1 one by one under the control of control unit 87 based on the type-up signal from timer unit 86 (for example, low-cost nighttime power). .

  In addition, the lunch system S includes a truck 91 that is a transport vehicle that can accommodate a plurality of, for example, three container devices 1. In this truck 91, three container devices 1 are carried from the provider to the provider or from the provider to the provider.

  Furthermore, the food supply system S includes an automatic cleaning device (not shown) that automatically cleans the food can a and the tableware b once taken out from the disinfection storage chamber 2 of the container device 1.

  Next, a method for providing food by the above-mentioned lunch system S will be described.

  A desired amount of cooked food is prepared by the provider based on ingredients corresponding to the meal menu of the provider, and the prepared food is stored in the food can a stored in the disinfection storage room 2 of the container device 1. Put in.

  Next, the container device 1 in which the food can a containing the cooked food and the tableware b stored in parallel in the tableware bowl are stored in the disinfection storage room 2 is loaded on the loading platform of the truck 91 and stored. Is delivered to the destination by truck 91.

  At the supply destination, the prepared food can a and tableware b are taken out from the disinfection storage room 2 of the container device 1 at the time of lunch, and the prepared dishes are placed on the tableware b placed on each person's tray. .

  After the end of lunch, the empty food can a is stored again in the sterilization storage chamber 2 of the container apparatus 1 while being dirty, and the table b collected from each person is stored in the sterilization storage room of the container apparatus 1 2 is housed again.

  And the container apparatus 1 accommodated in the disinfection storage room 2 with the empty food can a and tableware b being dirty is loaded on the loading platform of the truck 91 and accommodated, and the container apparatus 1 is carried by the truck 91 to the provider. .

  The provider first takes out the dirty food can a and the dirty tableware b from the disinfecting storage chamber 2 of the container apparatus 1 and inputs them into the input section of the automatic cleaning apparatus. Then, the food can a and the tableware b are automatically washed in the washing section of the automatic washing apparatus and then discharged from the discharge section of the automatic washing apparatus.

  Then, the washed food can a and tableware b discharged from the discharge unit of the automatic cleaning device are accommodated again in the disinfection storage chamber 2 of the container device 1 that has been cleaned (described later).

  Next, as shown in FIG. 2, the power supply device 85 installed at the provider and the three container devices 1 are electrically connected via the power line 81 to disinfect the sterilization storage chamber 2 of each container device 1. The food can a and tableware b inside are sterilized by heating.

  That is, when heating and disinfecting the food can a and tableware b at the provider, first, one power supply device 85 and the three container devices 1 are electrically connected via the power line 81, and then The sterilization start switch of the power supply device 85 is turned on. Then, for example, when the time is set in advance, for example, at 11 o'clock in the evening (the start of nighttime power), the first container device (unit 1) 1 of the three container devices 1 is connected to the commercial power supply 90. Night electricity is supplied.

  Here, when electric power is supplied to the container device (unit 1) 1, the heater 21 and the circulation are based on a control signal from the control means 51 in which the heating temperature and the heating time are preset in accordance with the food can a and tableware b. As a result, the food fan a and the tableware b in the sterilization storage room 2 are heated and sterilized by the hot air circulating in the sterilization storage room 2.

  Further, when the cooling fan 52 is operated based on a control signal from the control means 51, outside air is sucked into the accommodation chamber 30 from the suction port 45, and the control means 51 is cooled by the sucked outside air. Since the sucked outside air flows from the first chamber portion 56 with the control means 51 divided by the heating suppression plate 53 toward the second chamber portion 57 with the terminal portion 23 of the heater 21, the control means 51 21 and the temperature rise due to heat from the discharge pipe 63 is suppressed. The cooled outside air that has cooled the control means 51 is discharged out of the storage chamber 30 through the discharge port 46 while guiding the hot air discharged from the discharge pipe 63.

  When a preset time (timer set time), for example, 2 hours elapses and the timer unit 86 outputs a type-up signal, the power supply destination is automatically controlled by the control of the control unit 87 based on the type-up signal. This time, night power from the commercial power supply 90 is supplied to the second container device (No. 2) 1 and the food can a and tableware b are heated and disinfected in the same manner as the No. 1 unit. .

  For example, when the timer unit 86 outputs a type-up signal after two hours have passed, for example, the automatic switching of the power supply destination by the control of the control unit 87, this time for the third container device (No. 3) 1 Night electricity is supplied from the commercial power source 90, and the food can a and tableware b are heated and disinfected in the same manner as in the first and second machines.

  Thus, for the three container devices 1 connected to one power supply device 85, the night power from the commercial power supply 90 is sequentially controlled by the control unit 87 based on the type-up signal from the timer unit 86. As a result, the food can a and tableware b in the sterilization storage chamber 2 are heated and sterilized one by one.

  After the heat disinfection, the food can a and the tableware b are stored in the disinfection storage chamber 2 as they are until the next use. After the heat sterilization, the connector of the power supply line 81 is removed from the power supply connector portion 82 and the connection between the power supply device 85 and the container device 1 is released.

  By repeating the above steps, cooked dishes can be provided to the provider every day.

  On the other hand, the supplier also cleans the empty container device 1 itself when cleaning the food can a and tableware b. This is because the sterilized storage chamber 2 of the container apparatus 1 is easily spilled with cooked dishes when transported by the truck 91. For example, the inside of the sterilization storage chamber 2 of the container device 1 is washed with water using a hose or the like. At this time, all the four door portions 11 and 12 are folded open, and the disinfection storage chamber 2 is opened. Then, one door portion 11, 12, that is, the front door portion 11 and the rear door portion 12 on the left side of the front view covers the lower part of the suction port 45, and the other door portion 11, 12, that is, the front door portion 11 on the right side of the front view and The rear door 12 covers the lower part of the discharge port 46. For this reason, water drops do not easily enter the storage chamber 30 through the suction port 45 and the discharge port 46.

  And according to the said feeding system S, since it is equipped with the electric container apparatus 1 with the heating disinfection function which incorporated the heater 21, it is not necessary to necessarily install a steam supply equipment in providers, such as a feeding facility. The cost can be easily reduced and the place of use is not easily restricted.

  Further, since the power supply device 85 that connects and disconnects the plurality of container devices 1 supplies power to the plurality of container devices 1 in a predetermined number, for example, one by one in order, On the other hand, compared to the case where power is supplied at the same time, the peak of power consumption can be lowered and the electricity bill can be reduced.

  Furthermore, since the control means 51 of the container apparatus 1 which also serves as a disinfecting storage machine is cooled by the outside air by the operation of the cooling fan 52, it is adversely affected by the heat during the heat disinfection of the food can a and tableware b. The control means 51 can be appropriately protected from heat.

  Furthermore, since the entire control means 51 is disposed in the storage chamber 30 and covered with the cover 31, the control means 51 is less susceptible to the adverse effects of water during the cleaning of the container apparatus 1. Proper protection from water.

  Further, the heating suppression plate 53 disposed between the control means 51 and the terminal portion 23 of the heater 21 can suppress the control means 51 from being directly heated by the heat from the heater 21 and the discharge pipe 63. The control means 51 can be more appropriately protected from heat.

  Further, since the outside air inlet 45 and the outlet 46 are opened downward, and the lower portions of the inlet 45 and the outlet 46 are covered with the doors 11 and 12 in the folded open state, the container It is possible to appropriately prevent water from entering the storage chamber 30 during the cleaning of the apparatus 1, and the control means 51 and the electrical components other than the control means 51 located in the storage chamber 30 (the motor portion 27, the terminal portion 23 of the heater 21, The wiring portion or the like) can be more appropriately protected from water, and failure of the control means 51 and other electric parts can be eliminated.

  In addition, the lunch system S may provide cooked dishes for lunch from a provider to a provider using only one container device 1 or using four or more container devices 1.

  Moreover, the disinfection storage room 2 of the container apparatus 1 of the meal system S should just be what can accommodate at least the food can a and the tableware b.
