DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. In the present invention, the heat source may be gas or electric power. FIG. 1 is a schematic diagram of a system kitchen provided with an infrared sensor according to an embodiment of the present invention, FIG. 2 is an external view showing an example of a control unit of the system kitchen, and FIG. It is a functional block diagram of a kitchen. In FIG. 1, reference numeral 1 denotes a two-dimensional infrared temperature sensor (hereinafter, referred to as an infrared camera), which is installed so as to monitor the entire planar image of the gas table 2. The gas table 2 has a plurality of gas stoves, and the burners of the individual gas stoves have a structure in which the heating power can be adjusted by an output signal of the control unit 3. Further, the control unit 3 includes a display with a touch panel function for both temperature setting and temperature display, a thermal image and signal input / output unit, and a signal processing unit.

Next, the initial setting of the position of the gas stove on the gas table 2 will be described with reference to FIGS. Adjust the direction of the infrared camera 1 so that all the gas stoves are ignited and the thermal image is displayed in the center of the display 5 with the touch panel function of the control unit 3, and complete by pressing the initial setting button 4 of the control unit 3. I do. This initial setting may be performed only when the system kitchen is installed, when the gas table 2 is replaced, and when the direction of the infrared camera 1 is readjusted. By this initial setting, all gas stove positions are displayed on the display 5 with the touch panel function.

Next, the flow of the operation of the system kitchen configured as described above will be described with reference to the external view of the control unit in FIG. 2 and the functional block diagram in FIG. First, prior to the start of cooking, a gas stove to be used is specified on the display 5 with a touch panel. Subsequently, a cooking temperature suitable for the dish is input by using the up / down button 6, the fine adjustment button 7, and the setting button 8. At this time, in order to prevent danger, the upper limit of the set temperature is set in advance, and a setting exceeding the set value cannot be performed. Further, when the gas stove once set is no longer used for the time being, the setting can be canceled by the reset button 9. When the setting is completed, the burner of the gas stove is ignited, but a button for igniting and extinguishing may be provided in the control unit 3.

The display 5 with the touch panel displays both the set temperature and the current temperature based on a signal from the infrared camera. As shown in the functional block diagram of FIG. 3, these two temperatures are continuously compared and monitored, a prediction is calculated from a gradient of a change in the difference, and a signal for burner adjustment is output so as to appropriately control the fire. Here, only when the set temperature is set to a high temperature for fried food, etc., if the temperature changes flat for a long time (for example, 10 minutes or more) after the set temperature has been reached, the temperature may drop due to the addition of new ingredients. Since it is supposed to be detected, it is determined that the hook is kept on, and a burner extinguishing signal and a signal for warning are output. If the set temperature is less than 100 degrees Celsius and a temperature exceeding the set temperature is detected, the water in the cooking pot is depleted, it is judged that it is on the verge of burning, and a burner fire extinguishing signal and a signal for alarm are output. I do. Also, when the set temperature exceeds 100 degrees Celsius,
It does not normally occur because appropriate temperature adjustment is performed, but outputs a burner fire extinguishing signal and a signal for warning, notification, etc., for example, when spilled oil ignites and a temperature exceeding the set temperature is detected. .
