Abstract

PURPOSE:To reliably keep the temperature in a heating chamber within a certain range centering around the set temperature without being influenced by the outside temperature by a method wherein a heater is put into operation on the on-off duty corresponding to the set temperature when the detected temperature of a temperature sensor reaches the set temperature and at the same time said on-off duty is corrected by the outside temperature detected by the temperature sensor at the start of cooking. CONSTITUTION:A control unit 20 continuously operates heaters 7 and 8 by continuously turning ON thyristors, resulting in raising the temperature in a heating chamber and at the same time the heat generated by the heater 7 is given to a shape memory alloy coil 21. As a result, the shape memory alloy coil 21 contracts itself against the bias force of a spring 22 so as to shift a thermistor 30 to the neighborhood of an exhaust port 9 in order for the thermistor 30 to detect the temperature in the heating chamber. Thus, when the temperature in the heating chamber reaches the set temperature such as 250 deg.C, the control unit 50 turns ON and OFF the thyristors 41 and 42 on the predetermined on-off duty corresponding to the set temperature so as to start the intermitting action of the heaters 7 and 8. In this case, the control unit 50 corrects the on-off duty by the outside temperature memorized at the start of cooking.

First, before cooking starts, the heater 7 is not operating, so the shape memory alloy coil 20 is in an extended state due to the biasing force of the spring 22, and therefore the thermistor 30 is located near the exhaust port 10. There is. Then, oven cooking or grill cooking is set using the operation panel 3, and the heating room temperature is set. Then, when a cooking start operation is performed, the control section 50 takes in the detected temperature of the masters 3o, ie, the external temperature, and stores it in the internal memory.

Further, the control unit 5o first turns on the thyristors 41 and 42 continuously, and continuously operates the heater 7.8. When the heater 7.8 operates, the heat generated by the heater 7 increases the temperature in the heating chamber, and the heat generated by the heater 7 is applied to the shape memory alloy coil 21 through the exhaust port 9. In this manner, when the temperature of the shape memory alloy coil 21 reaches a predetermined value, the shape memory alloy coil 21 contracts against the biasing force of the spring 22, and the thermistor 30 moves to the vicinity of the exhaust port 9. In this case, the thermistor 3o comes to detect the temperature inside the heating chamber.

In this way, when the temperature in the heating chamber reaches a set temperature, for example, 250° C., the control unit 50 turns on and off the thyristors 41 and 42 with predetermined on and off duties corresponding to the set temperature, thereby causing the heaters 7 and 8 to operate intermittently. Start. In this case, the control unit 50 corrects the on/off duty based on the external temperature stored at the start of cooking.

Therefore, as shown in FIG. 5, if the external temperature is at the standard concentration, the heater 7.8 is driven with an on and off duty of 50%, for example, when the on period is 5 and the off period t2 is the same. If it is lower than the temperature, the on period fl
As ltt becomes longer (tta), the off period t2 becomes shorter (t2a), and the heater 7.
8 is driven. Further, when the external temperature is higher than the standard temperature, the off period t1 becomes longer (tlb) and the off period flt2 becomes shorter (izb), resulting in a small on-state.

オフデユーティでヒータ7.8が駆動される。Heater 7.8 is driven during off-duty.

Here, FIG. 6 shows the change in the heating chamber temperature when the external concentration is the standard temperature (dotted chain line in the figure) and the change in the heating chamber temperature when the external concentration is lower than the standard temperature (the solid line in the figure).
Even when the outside temperature is lower than the standard temperature, the temperature inside the heating chamber is maintained within a certain range around the set temperature, as in the case of the standard temperature.

In this way, at the start of cooking, the thermistor 30 is positioned near the exhaust port 10 of the main body 1 to detect the external temperature, and the detected temperature is memorized. It is located near the opening 9 to detect the temperature in the heating room, and when this detected temperature reaches a set temperature, it drives the heater 7° 8 with an on/off duty corresponding to the set temperature, and starts cooking with the on/off duty. Since the correction is made based on the external temperature stored at the time, the temperature inside the heating chamber can be reliably maintained within a certain range around the set temperature without being affected by the external temperature. Therefore, the food can always be cooked to a good quality without causing under-heating or over-heating.

Moreover, the thermistor 30 is made movable, and only one thermistor 30 is used to detect both the outside temperature and the temperature in the heating chamber, so the number of parts can be reduced and costs can be reduced. be. In particular, thermistor 3
As the means of moving the 0, we did not use a motor used as a general moving mechanism or a relay for controlling the energization of the motor, but instead adopted an extremely simple structure consisting of a shape memory alloy coil 21 and a spring 22, reducing costs. Of course, good assembly workability during manufacturing can be obtained, and furthermore, there are fewer failures and reliability can be greatly improved.
