題を有していた。FIG. 5 shows a conventional high frequency heating device with a humidity sensor. In the case of the humidity sensor, the moisture in the food boils and the humidity rapidly changes from a decrease to an increase. Therefore, by detecting this point, the end of cooking can be determined. Based on this, as shown in FIG. 5, the humidity sensor
The change in the resistance value of 27 is detected by dividing the voltage of the reference voltage power supply 28 with the resistance 29 to control the device. (For example, Japanese Patent Laid-Open No. 53-77365) In addition, there is a means for using a piezoelectric element instead of the humidity sensor as shown in FIG. Heat is transferred between the piezoelectric element sensor 1 and the boiling vapor, and a polarization current is generated by the thermal change, and the polarization current is detected to control the device. (For example, Japanese Unexamined Patent Publication No. 62-37624) Problems to be Solved by the Invention However, when the humidity sensor is used as described above, the gas or oil of food adheres to the humidity sensor during cooking and the detection sensitivity decreases. Therefore, it is necessary to evaporate the adhered substance of the humidity sensor with a heater or the like for the refresh heat treatment each time cooking is performed, which causes a problem that extra power and cost are generated.

課題を有していたのである。There is also a means of using a piezoelectric element instead of the humidity sensor, but since it has a structure in which the piezoelectric element sensor is attached to the conventional exhaust part or steam hole, it may receive boiling steam properly,
As the temperature of the sheet metal of the surrounding oven or body rises, the temperature of the piezoelectric element sensor also rises to a considerably high temperature. Here, since the piezoelectric element sensor produces an output according to the temperature difference ΔT between the boiling vapor and the piezoelectric element sensor itself, there is a problem that ΔT becomes small due to the temperature rise of the piezoelectric element sensor, and the output decreases. It was This is because the equipment is controlled according to the output of the piezoelectric element sensor, so if cooking is repeated and the temperature of the piezoelectric element sensor rises, the output of the same food item will decrease and the detection time will increase. Lead to things. That is, there is a problem in that a temperature correction element needs to be used or a software aspect needs to be devised, because variations in the finished response of cooking will occur.
