(Embodiment 1)
In the present invention, as shown in FIG. 1, the range hood 1 is provided above the cooking device 2 and includes a discharge port 3 communicating with the outdoors, a suction port 4 for sucking air, and an exhaust fan 5. The exhaust fan 5 sucks air from the suction port 4 and exhausts it from the discharge port 3 by its operation. The range hood 1 has a function of collecting oily smoke generated during cooking and discharging it outside. The cooking device 2 has a threshold value Tx that is the upper limit value of the cooking temperature in the automatic heating power adjustment function. The automatic heating power adjustment function detects the temperature of the bottom of the cooking device 8 by the temperature detection means, and automatically adjusts the heating power so that the detected temperature does not reach the threshold Tx or higher when the detected temperature reaches the threshold Tx. is there. In the initial state, that is, the cooking device 2 at the start of operation, a default value Ta is set as the threshold value Tx.

  The range hood 1 includes an operation switch 7 that determines the exhaust air volume of the exhaust fan 5 on the front surface of the hood portion 6, a thermoelectromotive force type temperature sensor 10 that detects the temperature T 1 of the food 9, and a person around the cooking area. A human sensor 11 for detecting presence or absence is provided. The thermoelectromotive force type temperature sensor 10 is provided below the hood portion 6, for example, below the operation switch 7, and for example, a thermopile is used. The human sensor 11 is provided on the side surface of the hood portion 6, for example, in the vicinity of the operation switch 7.

  And the control means A12 which produces the signal which varies the threshold value Tx which is the upper limit of cooking temperature based on the detection result of the human sensor 11, the signal produced by the control means A12, and the thermoelectromotive force type temperature sensor 10 Transmission means 13 for transmitting the detected temperature T1 is provided. The cooking device 2 includes a receiving unit 14 that receives a signal sent from the transmitting unit 13, and a control unit B 15 that controls the operation of automatic heating power adjustment based on a signal that changes the threshold Tx received by the receiving unit 14 and the temperature T 1. Consists of.

  In this invention, it is judged whether it is higher or lower than the threshold value Tx using the temperature T1 of the cooked food, and when the temperature T1 reaches the threshold value Tx, automatic thermal power adjustment is performed so as not to reach a temperature higher than the threshold value Tx.

  Next, the operation of the present invention will be described using the flowchart shown in FIG.

  In STEP 1, the temperature T 1 of the cooked food 9 in the cooking device 8 is detected by a thermoelectromotive force type temperature sensor 10 provided below the operation switch of the hood portion 6.

  The detection range of the thermoelectromotive force type temperature sensor 10 is shown in FIG. 3, and only the food 9 is detected, and the temperature T 1 of the food 9 is detected based on the amount of infrared rays emitted from the food 9. In addition, in order to increase the accuracy of temperature detection of the food 9, the number of objects of the food 9 detected by one thermoelectromotive force type temperature sensor 10 is one, and when detecting a plurality of foods 9, the food 9 The thermoelectromotive force type temperature sensor 10 according to the number is provided. When detecting a plurality of food items 9, the detected highest temperature is set as a temperature T <b> 1 of the food item 9 among a plurality of thermoelectromotive force type temperature sensors 10 provided for temperature detection.

  In STEP 2, whether or not a person is present around the cooking area is detected by a human sensor 11 provided in the vicinity of the operation switch 7 of the hood portion 6. The detection range of the human sensor 11 is shown in FIG. The detection range enables detection of not only the front surface of the cooking device 2 but also the periphery of the cooking device 2, for example, a cooking place including an adjacent washing place.

  In STEP 3, the control means A 12 determines the presence or absence of a person, and in STEP 4 and STEP 5, a different signal is generated depending on the determination result. Specifically, when it is determined in STEP 3 that a person is present, in STEP 4, the control means A12 changes the threshold value Tx, which is the upper limit value of the cooking temperature, to a value higher than the normal value Ta that the cooking device 2 has. Create C. On the other hand, if it is determined in STEP 3 that there is no person, the control means A12 generates a signal D that sets the cooking temperature threshold Tx to a normal value, that is, the default value Ta possessed by the cooking device 2 in STEP 5.

  The signal created by the control means A12 in STEP4 or STEP5 and the temperature T1 detected by the thermoelectromotive force type temperature sensor 10 in STEP1 are transmitted to the receiving means 14 of the cooking device 2 by the transmission means 13 in STEP6.

  In STEP 7, the receiving means 14 provided in the cooking device 2 receives a signal sent from the transmitting means 13 provided in the range hood 1. At this time, when the receiving means 14 receives the signal C, in STEP 8, the control means B15 changes the cooking temperature threshold Tx to a value Tb that enables cooking at a high temperature. When receiving means 14 receives signal D, control means B15 sets threshold value Tx, which is the upper limit value of cooking temperature, to normal value Ta. The relationship between the value Ta and the value Tb is Ta <Tb. For example, when the default value Ta = 180 ° C. and the value Tb = 230 ° C., when the signal C is received, the threshold Tx = Tb = 230 ° C. is set. Therefore, at the threshold Tx = 230 ° C., cooking in a high temperature region where cooking is not possible in the default state (Tx = Ta = 180 ° C.) is also possible. Then, automatic thermal power adjustment is performed according to the temperature T1 of the food 9 detected by the thermoelectromotive force type temperature sensor 10 and the changed threshold value Tx.

  Further, when the cooking device 2 is in operation, the operations from STEP 1 to STEP 8 are repeatedly executed at regular time intervals, and when the cooking device 2 stops operating, the threshold value Tx that is the upper limit value of the cooking temperature is a normal value. Returning to Ta, the execution of these operations is terminated.

  For example, at the threshold Tx = Ta = 180 ° C., the temperature T1 of the cooked food gradually rises, and when the temperature T1 reaches 180 ° C., the automatic heating power adjustment function is turned on so that the temperature T1 becomes 180 ° C. or less. Adjusted to firepower.

  In the conventional technique, the temperature of the bottom of the cooking device 8 is detected, and the temperature of the bottom of the cooking device 8 is higher than the temperature of the food. Therefore, when the threshold Tx = Ta = 180 ° C., the temperature T1 = 160 ° C. of the cooked food, and the temperature of the bottom of the cooking utensil 8 is 180 ° C., the temperature T1 of the cooked product is 160 lower than the threshold Tx (= 180 ° C.). Regardless of the temperature, the temperature at the bottom of the cooking device 8 becomes the threshold value Tx (= 180 ° C.). Therefore, the control means B15 of the cooking device 2 determines that the temperature of the bottom of the cooking device 8 has reached the threshold value Tx, and the automatic heating power adjustment function is turned on.

  In the present invention, when the human sensor detects that a person is present around the cooking area, the threshold Tx is set to Tb = 230 ° C., which is a value higher than the normal value Ta (= 180 ° C.). By setting the threshold value to Tb, the cooker can increase the heating power up to 230 ° C., and by detecting the cooking temperature T1, the cooking temperature described above is low, but the automatic heating power adjustment is ON. It becomes possible to perform automatic heating power adjustment with high accuracy.

  The heating device control system according to the present invention can realize cooking at a temperature required by the cook and can also cook at a high temperature, so that it is useful for general household use.
