Hereinafter, the present embodiment will be described with reference to the flowchart of FIG.

When the power is turned on to the oven toaster, the object to be heated is placed on the grill 6 in the main body 1 and the cooking start key 10 is turned on (101), the cooking start key 10 sends a signal to the control means 9. Is output, and a signal is input to the cooking condition correction means 12 by the duty ratio storage means 13, and even if the last cooking has been performed (102), the last cooking menu is the frozen pizza toast (118) and the last cooking time is Is 10
If the energization rate of the heat source at 120 seconds immediately before the end of the previous cooking is 90% or more (127), the correction to the interval time input by the interval time measurement timer 4 is not performed, and it is less than 90%. In the case of (127), a signal is output from the interval time measurement timer 4 to the cooking condition correction means 12, and the interval time is increased by +40.
If the second cooking time is corrected (123) and the last cooking time is 10 minutes or more (120), and if the energization rate of the heat source in the last 120 seconds immediately before the last cooking is less than 80% (126), the interval time is +70 seconds. The correction (122) is performed, and if it is 80% or more (126), the correction (124) of +65 seconds is performed in the interval time. The last cooking menu was not frozen pizza toast (118), and the cooking time was 10 minutes or more (10
3) If the energization rate of the heat source for 120 seconds immediately before the end of cooking is 60% or more (125), the correction to the interval time is not performed, and if it is less than 60% (125), the interval time is increased by +100 seconds. The correction (121) is performed. If the cooking time is less than 10 minutes (103), the correction (121) of +100 seconds is performed in the interval time.

Then, the temperature input to the control means 9 from the temperature sensor 5 and the previous cooking (102)
Furthermore, if the correction to the interval time is performed, the corrected interval time is used, and if the correction is not performed, the correction is not performed, that is, the prediction is performed using the temperature sensor 5 and the cooking condition correction unit 12 as inputs. In the means 7, the inside temperature at the time of cooking start is predicted by fuzzy inference, and a signal is outputted to the prediction means 7 by the control means 9 and to the control means 9 by the prediction means 7 to determine the current heating cooking time ( After 105), the control means 9 outputs a signal to the cooking time measurement timer 8, resets the cooking time measurement timer 8 (106), and starts cooking (107).
At the same time, the control means 9 outputs a signal to the cooking time measurement timer 8 to start the measurement of the cooking time (108). However, if the last cooking time was less than 120 seconds,
The energization rate is calculated assuming that the time obtained by subtracting the previous cooking time from 120 seconds is not energized.

During cooking, the control means 9 outputs a signal to the heater 3 to heat the object to be heated. If the cancel key 11 is not turned on (109) on the way, the cooking time elapses (110).
(109) and the subsequent steps are repeated until the cooking time has elapsed (110). If the cooking time has elapsed (110), the control means 9 turns off the signal output to the heater 3 and ends the cooking (111). 9, the control means 9 outputs a signal to the time condition storage means 13 so that the cooking menu and
The power supply rate of the heater and the cooking time for 20 seconds are stored, and the control means 9 outputs a signal to the interval time measurement timer 4 so that the interval time measurement timer 4
Is reset (112), the measurement of the interval time is started (113), and the steps after (101) are repeated. However, when the cancel key 11 is turned on (109) halfway, the cancel key 11 inputs a signal to the control means 9, and the control means 9 turns off the output of the signal to the heater 3 and stops cooking halfway. (101) and subsequent steps are repeated. In this embodiment,
The time was set to 120 seconds immediately before the end of the previous cooking, but may be set to 150 seconds or 180 seconds if the capacity of the microcomputer is sufficient.

As described above, in the present embodiment, when the last cooking has been performed, the cooking is started according to the last cooking menu, the last cooking time, and the heater energization rate for 120 seconds immediately before the last cooking is completed. Sometimes, by correcting the interval time, the optimum heating and cooking time can be determined, and the degree of baking of the object to be heated can be kept constant and the object to be heated can be cooked deliciously.

[0063]

As described above, according to the first to seventh aspects of the present invention, the influence of the cooking performed last time is corrected to determine the optimum heating cooking time this time, so that the variation in the cooking performance is obtained. Can be provided, and an oven toaster that can keep the degree of baking of the object to be heated constant can be provided.
