Abstract

PROBLEM TO BE SOLVED: To prevent bread from failing to be toasted by prolonging cooking time by a given period of time in accordance with a switching off time of a heater in the case that the heater is turned off during cooking of the bread or the like because the temperature in a heating chamber becomes not less than a given high temperature. SOLUTION: A main body 1 is provided with a heating chamber 2 for cooking and heating an object to be heated. The temperature in the heating chamber 2 is detected by a temperature sensor 4 serving as a temperature detecting means. When the temperature sensor 4 detects not less than a given high temperature while bread is being cooked, a control means 9 temporarily switches off a heater 3 provided in the heating chamber 2, and when the temperature sensor 4 detects a temperature not more than the given high temperature, the heater 3 is again switched on, and further a predetermined cooking time is prolonged by a predetermined period of time in accordance with the temporary switching off time of the heater 3. In this way, a failure of toasting bread can be prevented.

(Embodiment 1) Hereinafter, embodiments of the present invention will be described.
This will be described with reference to FIG. In FIG. 1, 1 is a main body, 2 is a heating chamber provided in the main body for cooking and heating an object to be heated, 3 is a heater provided in the heating chamber, and 4 is a temperature inside the heating chamber formed of a temperature sensor. , A grid for placing an object to be heated, 6 a power switch for turning the power on and off, 7 a cooking start switch for starting the cooking of the bread, and 8 until the cooking of the bread is completed. And a time indicator 9 constituted by an LED or the like for displaying the remaining time. When cooking the pan, the heater 9 is turned off temporarily when the temperature sensor 4 detects a temperature higher than a predetermined high temperature. The control means has a function of turning on the heater again when the temperature of the sensor becomes lower than a predetermined high temperature, and extending the cooking time from a preset cooking time by a predetermined time corresponding to a time when the heater is temporarily stopped.

The operation of the heating cooker configured as described above will be described with reference to the flowchart of FIG. First, it is monitored at 101 whether or not the cooking start SW has been pressed, and when the cooking start SW has been pressed, heating cooking is started at 102. At 103, it is monitored from the signal of the temperature sensor 4 whether the temperature θ in the heating chamber is 280 ° C. or higher or lower than 280 ° C. If it is lower than 280 ° C., the process moves to 104, and the preset heating time T4 has elapsed from the start of cooking. Monitor
When the heating time T4 has elapsed, the process is terminated. If the temperature is 280 ° C. or more at 103, the heater is turned off at 105, the measurement of the elapsed time since the heater is turned off is started at 106, and the temperature θ in the heating chamber is set at 280 at 107.
It is monitored whether it is over 280 ° C or below 280 ° C. If it is over 280 ° C, it returns to 106.
Calculation is performed based on the time measured in 6 to determine the heating extension time Tα. Further, the heater is turned on again at 109, and it is monitored at 110 whether or not the time T4 + Tα has elapsed since the start of cooking. Here, the case where the temperature in the heating chamber becomes 280 ° C. or more and the heater is turned off once has been described, but the same operation is performed when a plurality of times occur.

Next, a supplementary explanation of the operation will be given with reference to FIG.
(A) is a change diagram of the temperature of the temperature sensor during the cooking of bread,
(B) is an operation diagram of a heater showing a conventional example, and (c) is an operation diagram of the heater when extension cooking is performed. First, when cooking starts, the heater is turned on, and the control means 9 detects the temperature θ0 in the heating chamber at the time of starting cooking and the temperature θ1 in the heating chamber after a lapse of T1 time from the start of cooking from the signal from the temperature sensor 4, and detects θ0. And a heating time T4 is calculated from θ1. In addition, the remaining cooking time is output to the time display 8 based on the calculated T4. Also, since the heater is turned off when the temperature in the heating chamber reaches 280 ° C. or higher due to safety, heat resistance temperature of parts, etc. by the end of cooking, the temperature in the heating chamber at the time of starting cooking in continuous cooking, etc. If the temperature is high, the temperature in the heating chamber becomes 280 ° C. or higher at T2, and the heater is turned off. Thereafter, the temperature in the heating chamber slightly rises due to residual heat or the like, and then falls. At T3, the temperature in the heating chamber becomes lower than 280 ° C., and the heater is turned on again. Here, the control means 9 determines the time T during which the heater was off.
An arithmetic processing is started from OFF to calculate the cooking extension time Tα.
As an example of the arithmetic processing, Tα = TOFF × (0.2
To 0.8), and the coefficient of 0.2 to 0.8 can be individually set according to the type of cooking, the temperature of the heating chamber at the start of cooking, and the like. Thereafter, the temperature in the heating chamber slightly decreases, but increases due to heat from the heater. Cooking ends at the calculated T4. If the temperature in the heating chamber becomes 280 ° C. or higher and the heater is turned off, the cooking (heater is turned on) is extended by the calculated Tα time.

(Embodiment 2) In the embodiment 2, during the cooking extension time Tα, the cooking extension time is displayed while the remaining time is blinked by the notification means 8 using a time indicator such as an LED shown in FIG. Notify that. Although the time indicator is used as the notification means, notification by sound or the like can be considered.

(Embodiment 3) In Embodiment 3, the heating chamber is 2
During the time when the temperature is 80 ° C. or higher and the heater is turned off, the notification means 8 performs the notification while blinking or the like.

[0013]

As described above, according to the first aspect of the present invention, when the temperature in the heating chamber at the start of cooking due to continuous cooking is high, or when the ambient temperature is high and the temperature in the heating chamber rises quickly, It is possible to prevent a problem that the bread does not turn brown during the preset cooking time due to the heater being turned off during the cooking.

Further, according to the second aspect of the present invention, the user can easily know that the time is extended when cooking is extended, and can alleviate irritation during the waiting time until the cooking is completed. .

Further, according to the third aspect of the present invention, the user can use the apparatus without worrying that the heater may be turned off due to a trouble such as a failure.
