By stopping the heating of the cooking, the water vapor from the cooking will be reduced and the gas sensor will be near 42 As the water vapor concentration decreases, the internal resistance Rs of the gas sensor 42 increases. Here, when the transistors Q5 and Q6 are turned on, the emitter potential of the transistor Q5 is the divided voltage of the internal resistance Rs and the resistor R10, and the base potential is the divided voltage of the parallel combined resistance of the resistors R12 and R14 and the resistor R13. . 7. Therefore, when the internal resistance Rs is increased so that the emitter potential of transistor Q5 becomes lower than the base potential (water vapor concentration decreases), transistor Q5 is cut off, and transistor Q6 is also cut off. At this time, the transistor Q4 will turn on again. By turning on the transistor Q4, a current flows to the relay 51, and the micro-wave oscillating part 16 is started to be energized again. At this time, the cooking contents in the container 4 are heated again, and as a result, the water vapor concentration starts to increase. 8. For example, when cooking porridge, the problem that the soup head overflows from the container 4 due to heating occurs. Even if the time constant is used to control the on / off control of heating to control overheating, if the energization rate is high, it will overflow during cooking. At this time, in order to prevent the soup from overflowing before cooking is finished, the energization rate can be set low. However, it takes longer to cook. Therefore, this circuit is to use the internal resistance Rs when the water vapor in the heating chamber 1 is high just before the soup head overflows, and set the values of R 1 0, R 1 3, and R 1 4 to R in advance. sb: R 1 0 = R 1 3: R 1 4. Therefore, the transistor Q5 will stop heating due to the conduction immediately before the overflow, and K will prevent the overflow. The reverse voltage Vr at that time was Vr = VccX R14 / (R13 + R14) = Vccx R10 / (Rs + R10). However, Vcc is the DC voltage 5V of the first power circuit section 20 〇 ^-Ί ----- ^ ..

Description of the invention () Transistors Q5 and Q6 are on The base potential Vb of the transistor Q5 when the oscillation of the microwave is stopped is when the parallel combined resistance of the resistors R12 and R14 is taken as Rpl, then Vb = VccXRpl / (Rpl + R13). However, Rpl = R12XR14 / (R12 + R14) 〇 The emitter potential Ve is, because it is Ve = VccXR10 / (Rs + R13), the heating of the cooking is stopped, and the water vapor concentration will decrease, and the internal resistance Rs will slowly As the ground becomes larger, the transistor Q5 is cut off at the point of Vb> Ve, and the transistor Q6 is cut off immediately. Because the transistor Q6 is cut off, the base current flows to the transistor Q4 again, so the transistor Q4 will also be turned on. As a result, the current will flow to the microwave vibrating portion 16 of the relay 51, and the cooking in the container 4 will be heated until immediately before it overflows again. When the transistor Q5 is cut off, that is, when the internal resistance Rs when the water vapor concentration in the heating chamber 1 is very low is taken as Rst, the microwave oscillating part 16 repeatedly vibrates and stops in the range of RsbS Rs and Rst. . However, Rsb = R10XR14 / R13, Rst = R10XRpl / R13. As shown in FIG. 5, the time when the internal resistance Rs of the gas sensor 42 changes from Rsb (plus) to Rst is the time when the microwave oscillator 16 stops, that is, the time when the relay 51 is turned off (electric scraper 0V). The time for the internal resistance Rs to change (decrease) from Rst to Rsb is the time for the microwave oscillating part 16 to vibrate the microwave, that is, the time for the relay 51 to be turned on (24V). In addition, the internal resistance Rs of the gas sensor 42 is due to the relationship of Rst > Rsb, so in the case of R13 < R14, in order to satisfy R12 > R132X R14 / (R142-R132), it is necessary to set the resistance R12.

Description of the invention (16) The base side of the transistor Q2 of the conduction rate control unit 60 is connected. When the switch SW2 of the function 2 setting section 71 is turned on, the heater is controlled by the control of the conduction rate control section 60 by the M gallbladder. The aforementioned capacitor C9 and resistor R21 are equivalent to the function 2 stop circuit of the present invention, and the capacitor C10 and the power amplifier R28 of the function 2 setting section 71 are equivalent to the function 1 stop circuit. As shown in FIG. 9U), the operation unit 5 in this embodiment is provided with a function 1 selection key 70a and a function 2 selection key 71 a, as well as a separate adjacent sliding adjuster 7 and a function 1 selection key. 71a and function 2 selection key 71a, the aforementioned LED1,2, M, and timer knob 6 for setting the cooking time. The sliding regulator 7 is a device that can change the resistance value K of the variable resistor VR provided in the conduction rate control section 60 to adjust the output (the conduction rate). Next, the action will be explained. 1. When the KI timer knob 6 sets the cooking time and presses the function 1 selection key 70a, the power (5V) of the first power source circuit section 20 is respectively applied to the control section 40 with the sensor and the energization rate. The control unit 60 and the power (24V) of the second power circuit unit 25 are applied to the function 1 setting unit 70. At this time, the switch SW1 is turned on by pressing the function 1 selection key 703, and the current instantly flows through the capacitor C9 to the bases of the transistor Q8 and the transistor Q11 of the function 2 setting section 71. This is a heating controller for canceling the setting by the function 2 setting section 71. After that, the capacitor C9 will be fully charged immediately because the capacity is as small as 0.01 / iF. Therefore, the leading current flows to the transistor Q7 side as the emitter current, and the transistor Q7 is turned on. As a result, transistor Q9 is turned on and lights up LED1, and at the same time, the base of transistor Q6 with sensor control section 40 is turned on--v- 丨 萍 i-/-T 1 (Please read the precautions on the back first (Fill in this page again) This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 18 39227 Employees' Cooperatives of the Central Standards Bureau of the Ministry of Economy printed A7 B7 V. Description of the invention (17) Short circuit to M and prevent The control unit 40 of the sensor controls the heating. In addition, the transistor Q16 is turned on in conjunction with the turning-on operation of the transistor Q9. 2. At this time, the transistor Q4 provided in the relay driving section 52 of the switching section 50 is turned on due to the bias current of the collector current of the transistor Q16, and a power source of 24V is applied to the relay 51. When a current flows through the relay 51, the relay contact 51a is turned on, and a commercial power source is applied to the microwave oscillating portion 16. 3. On the other hand, the smoothing capacitor C6 is charged when the power-on control unit 60 is applied with power, and the base potential (based on the divided voltage generated by the variable resistor VR and the resistor R6) is cut off because it is higher than the emitter potential. . As the smoothing capacitor C6 charges, the emitter potential becomes higher. When the base potential is exceeded, the transistor Q2 is turned on, and the transistor Q3 is turned on. Since the collector of the transistor Q2 is connected to the base of the transistor Q3, and the base of the transistor Q2 is connected to the collector of the transistor Q3, K will maintain the conduction state with each other. When the transistor Q3 is turned on, the aforementioned partial voltage value is in a short-circuited state, and its value becomes about 0.4V (the saturation potential when the transistor Q3 is turned on). 4. When the transistor Q3 is turned on, the transistor Q4 of the relay driving section 52 is cut off because the bias current to the base is blocked. In conjunction with this, the power to the relay 51 is cut off and the relay contact 51a is opened. 5. After that, the charge of the smoothing capacitor C6, that is, the path of the K resistor R44 transistor Q24 transistor Q3 is discharged, and the transistor Q2 is cut off when its emitter potential drops below the aforementioned 0.4VM, and the transistor Q3 will also be linked to this However, after truncation, M will repeat the actions of one of the previous queues in a predetermined cycle.
