Description

[Detailed explanation of the idea] (b) Industrial use The present invention relates to an electronically controlled cooker.

(b) Prior Art A cooking device equipped with a plurality of heat sources for cooking is well known, as seen, for example, in Japanese Patent Publication No. 14235/1983. In conventional cookers of this type, each heat source was not driven simultaneously due to household power capacity. However, such power capacity in Western countries is sufficiently large that it is possible to drive each heat source simultaneously.

(c) Problems to be Solved by the Invention The present invention provides a cooking appliance that can drive multiple heat sources simultaneously and allows the operating status of each heat source to be easily recognized.

(d) Means for solving the problem The cooker of the present invention has multiple heat sources for cooking,
It is equipped with a means for individually setting the drive timer time length of each of the heat sources, a numerical display means, an indicator provided corresponding to each of the heat sources, and a control means, and the control means is configured to control the simultaneous driving of the plurality of heat sources. a determining means for determining whether or not an instruction has been given; a driving means for driving each heat source and a corresponding indicator by a set corresponding drive timer time when the determining means makes an affirmative determination; and when the determining means makes an affirmative determination; , a comparison means for comparing drive timer time lengths of the respective heat sources, and a display means for displaying the longest timer remaining time on the numerical display means based on the comparison result of the comparison means.

(E) Effect According to the present invention, multiple heat sources are driven in parallel with individual timer time lengths, but at this time, the longest timer remaining time is displayed, so multiple timer time lengths are used. Nevertheless, since the cooking end point is clear and the indicator operates in accordance with the driving state of each heat source, it is possible to immediately recognize which heat source is being driven.

(F) Embodiment FIG. 2 shows an electrical circuit diagram of an embodiment of the present invention. Commercial power is supplied to the first heat source 1 and the second heat source 2 through a first switch 3 and a second switch 4, respectively. In this embodiment, the first heat source 1 is an electric heater,
The second heat sources 2 are each configured with a microwave oscillation circuit, but are not limited to these. The first and second switches 3 and 4 consist of bidirectional thyristors.

The control means 5 consisting of a microcomputer is
Based on the instruction information entered from the keyboard 6 and the output of the temperature sensor 7 that detects the temperature of the cooking chamber, the first and second switches 3 and 4 are controlled, and the remaining time of the timer is displayed on the numerical display means 8. Indicators 9 and 10 consisting of lamps and the like provided for the first and second heat sources 1 and 2 are driven. Note that an interface 11 is provided as an input/output section for the control means 5.

The functions of the cooking device of this embodiment are as follows: (A) First heat source 1
(B) independent operation of the second heat source 2, (C) sequential operation of each heat source, (D) simultaneous operation of each heat source, etc.

The operations (A), (B), and (C) above are well known, and will be briefly described.

In case (A), use the keyboard 6 to specify the first heat source 1, the set temperature, and the timer time length.
Finally, when the start key is operated, cooking is started, and the first heat source 1 is driven to maintain the cooking chamber temperature at the set temperature during the timer period.

In case (B), use the keyboard 6 to specify the second heat source 2 and the timer time length, and finally operate the start key to start cooking. During the timer time length, the second heat source 2 is driven.

In case (C), use the keyboard 6 to specify both cases (A) and (B) above, and specify the execution order of each heat source, and then press the start key to start cooking. Operations (A) and (B) are executed in the order specified.

Simultaneous operation of each heat source in (D) is a feature of this embodiment, and an example of key operation in this case is as follows.

DUAL Microwave 5 Heater 1 0
Temperature 9 0 Start In this example, heater heating by the first heat source 1 and microwave heating by the second heat source 2 are started simultaneously after pressing the start key, the former heating takes 10 minutes, and the latter heating takes 5 minutes. Each ends with . When heating the heater, the cooking chamber temperature is
Maintained at 90℃. Then, the longest timer remaining time among both heating sources, that is, in this case, the timer remaining time for heater heating is displayed on the numerical display means 8, while while each heat source is being driven, the corresponding indicators 9, 1
0 is driven.

FIG. 1 shows a program stored in the control means 5 to perform the control operation in case (D) above.

This program is started by operating the start key, and first, by checking whether or not the DUAL key has been operated in advance, it is determined whether or not each heat source is to be driven simultaneously. If they are not driven simultaneously (that is, in cases (A), (B), and (C) above), normal processing is performed.

In the case of simultaneous driving, both the heater and microwave heating are started, and the indicators 9 and 10 corresponding to both heating are lit, and the flag DF is turned on.
is set.

Next, the input time lengths of both timers are compared, and if the heater timer time length is longer, the number display means 8 displays the step of displaying the remaining time of the heater timer and turning on the heater to maintain the cooking chamber temperature at the set temperature. Offstep is executed repeatedly.
Since the remaining time of the microwave timer becomes "0" first, the microwave heating is stopped at this time, the microwave indicator 10 is turned off, and the flag DF is reset. Thereafter, the heater timer remaining time display step and the set temperature maintenance step are repeatedly executed, and when the heater timer remaining time reaches "0", the heater heating is stopped, the heater indicator 9 is also turned off, and cooking is completed.

On the other hand, if the microwave timer time length is longer, the step of displaying the remaining time of the microwave timer and the step of maintaining the set temperature are repeatedly executed on the numerical display means 8. Since the remaining time on the heater timer reaches "0" first, the heater heating is stopped at this time, and the heater indicator 9 is turned off.
Furthermore, flag DF is reset. Thereafter, the microwave timer remaining time display step continues to be executed repeatedly, and when the microwave timer remaining time reaches "0", microwave heating is stopped, the microwave indicator 10 is also turned off, and cooking is completed.

(g) Effects of the invention According to the invention, in a cooker capable of simultaneously driving a plurality of heat sources, the operating state of each heat source can be easily recognized.
