In the present invention, a large number of such carts are stored and stored in the refrigerator, and then heating is started by setting the time in time for the catering time. The heating start timing is simultaneously supplied to the respective carts. By taking it in, it is no longer necessary to set the heating start time for each bar cart.
[0020]
FIG. 1 is a system configuration diagram of a heating control device for a food cart according to the present invention. In FIG. 1, 1 is a controller, 2 is a power supply control panel, 3 is a power supply control device, 4 and 5 are electromagnetic switches, 6 is a refrigerator, 7 and 8 are outlets, 9 is a cold air discharge port, and 10 to 12 are serving carts. , 13 to 15 are power cables.
[0021]
Outlets 7 and 8 are provided in the refrigerator 6, and the power cables 13 to 15 of the distribution carts 10 to 12 are connected to them. The outlets 7 and 8 are connected to an AC 200V power source via electromagnetic switches 4 and 5, respectively. The electromagnetic switches 4 and 5 are controlled to be turned on and off by a power supply control device 3 having a timer, and the timer of the power supply control device 3 is set by a controller 1 having a display and an input device.
[0022]
The electromagnetic switches 4 and 5 may be turned on / off at the same time, or individually turned on / off at different times. If it is like the former, the heating of all the distribution carts 10-12 in the refrigerator 6 can be started simultaneously. Further, if the latter is used, for example, the start of heating can be set separately from the dinner carts 10 to 11 and the breakfast cart 12 for breakfast.
[0023]
After power is turned on to each of the layout carts 10 to 12, control is performed by a control unit built in each of the layout carts 10 to 12. The control unit is switched to the heat retention mode after heating for a predetermined time. And when it is just before the distribution time, the electromagnetic switches 4 and 5 are turned off by the power supply control device 3, and the power supply of the distribution carts 10 to 12 is cut off.
[0024]
FIG. 4 is a control system diagram in the layout cart. For example, the control panel 17 is configured as shown in FIG. 5, and various display lamps that indicate whether the power is on, whether heating is currently being performed, whether the door is open, whether the operation has been stopped, etc. A display for displaying the set time, an input button for changing the heating time, a heating restart button, a stop / reset button, and the like are provided.
[0025]
The control unit 26 has a built-in timer that operates according to a program, and operates the oscillation circuits 27 to 30 for a time set on the control panel 17 from when the power is turned on, so that the induction heating coil is in a heating mode. Operate and then switch to warming mode. In addition, as shown in FIG. 3, each of the oscillation circuits 27 to 30 shares an induction heating coil in each vertical row of compartments of the layout cart divided into four stages.
[0026]
Although not shown, the door 18 is provided with a door switch for detecting opening and closing, and when the door 18 is opened during heating, the oscillation circuits 27 to 30 are immediately stopped for safety. I try to secure it. In addition, when the door 18 is opened during heating due to the addition or replacement of the tray 20, the stop / reset button is pressed once to stop the heating, and then the door 18 is opened. Then, immediately after the door 18 is closed and the restart button is pressed, the heating is started again until the remaining time elapses. If the door 18 has been left open for a long time due to forgetting to close the door 18, mischief, or the like, heating is performed from the beginning by pressing the restart button twice.
[0027]
The setting time of the timer of the control unit 26 has a fixed value fixed in advance and a variable setting value that can be changed at any time, and normally operates with a fixed value. However, when a variable setting value is input, The next heating operation is performed at the input set time, and thereafter, the heating operation is performed at a fixed value. In this way, when a special dish having a heating time different from that of a normal dish is served, it is possible to easily cope with it, and thereafter, the original heating time is restored without changing the setting.
[0028]
The variable setting value is input by pressing the “Program” button on the control panel 17, operating the “Data Input” button while watching the time display on the display unit, and adjusting the desired time. Press “” button to confirm.
[0029]
On the other hand, when a failure occurs for some reason during heating, the failure is displayed on the control panel 17, but at that time, not all the oscillation circuits 27 to 30 of the layout cart are stopped, but the failure occurs. Only the oscillation circuit that shares the system is stopped, and the other oscillation circuits continue to operate. In this way, the influence of the failure is minimized. Then, if the faulty system can be displayed on the display device, the later response becomes easier.
[0030]
