Abstract

An electronic controlled heat cooking apparatus having a plurality of heating mode designating keys and a timer allotted to each of a plurality of blocks for setting heating conditions of an oven. A random access memory included in a microprocessor stores which block'"'"'s heating mode designating key was first operated from the plurality of blocks and also stores the set heating mode and the time period set by the timer of that block. The microprocessor is responsive to an operation of a start key to select the heating modes of the oven in accordance with the order as stored in the random access memory and enable the oven'"'"'s appropriate heat source in the selected heating mode for the set time period of the corresponding timer. Each timer has a displaceable operation knob, and a digital display is provided to display the timer time period information set by the knob.

Claims

1. An electronically controlled heat cooking apparatus, comprising:

heating energy generating means for providing heating energy to a material being cooked,

entry means for setting heating conditions corresponding to a desired plurality of heating modes successively set in an arbitrary sequence for cooking said material being cooked by means of said heating energy generating means;

said entry means comprising a plurality of groups of heating condition setting means for independently establishing signals corresponding to said heating conditions of a desired heating mode;

each said group of heating condition setting means comprising heat designating means for setting the heat to be applied during a single heating mode, and timer time period entry means for setting a timer time period corresponding to the desired duration of said single heating mode;

storing means for storing signals corresponding to said heating conditions set by said plurality of groups of heating condition setting means and to the sequence in which said groups were successively set,

said storing means comprising heat storing means for storing the heat settings entered by said heat designating means, timer time period storing means for storing said timer time periods entered by said timer time period entry means, and sequence storing means, responsive to the sequence in which an operator sets said groups, for identifying the sequence in which said groups have been set regardless of which group said operator chooses to set first;

heat start commanding means,

control means responsive to the output of said heating start commanding means and to said signals stored in said storing means for controlling said heating energy generating means to perform said desired sequential heating modes in accordance with the order stored in said order storing means and the heating conditions stored in said heat storing means and said timer time period storing means, and

said cooking apparatus further comprising an operation portion having a plurality of discrete sections, each of said sections having a respective group of heating condition setting means disposed therein.

2. An electronic controlled heat cooking apparatus in accordance with claim 1, wherein

at least one of said heat designating means comprises strong heat designating means for designating a relatively strong heating operation by said heating energy generating means and weak heat designating means for designating a relatively weak heating operation by said heating energy generating means, and

said control means enables said heating energy generating means to generate said energy with a relatively strong intensity when said storing means stores that said strong heat designating means was operated and enables said heating energy generating means to generate said energy with a relatively weak intensity when said storing means stores that said weak heat designating means was operated.

3. An electronic controlled cooking apparatus in accordance with claim 2, wherein said heating energy generating means comprises microwave generating means.

4. An electronic controlled heat cooking apparatus in accordance with claim 1, wherein

said heat energy generating means comprises microwave generating means and heater means,

at least one of said heating designating means comprises microwave heat designating means for designating the heat by said microwave generating means and heater heat designating means for designating the heat by said heater means, and

said control means selectively enables said microwave generating means when said storing means stores that said microwave heating designating means was operated and selectively enables said heater means when said storing means stores that said heater heat designating means was operated.

5. An electronic controlled heat cooking apparatus in accordance with claim 1 which further comprises left time period evaluating means for evaluating a left time period based on said timer time period stored in said timer time period storing means and an operation time period of said heating energy generating means, and

display means for displaying a left timer time period as evaluated by said left timer time period evaluating means.

6. An electronic controlled heat cooking apparatus in accordance with claim 5, which further comprises

section display means for displaying which one of said groups of heating condition setting means is associated with said left time period display by said display means.

7. An electronic controlled heat cooking apparatus in accordance with claim 5, 6 or 1, wherein

said timer time period entry means comprises means displaceably operable over a predetermined range from an origin position for entry of said timer time period, and further comprises code signal generating means operatively coupled to said displaceble entry means for generating a code signal which varies according to the displaced amount from said origin position of said displaceable entry means, and

said timer time period storing means stores said timer time period based on said code signal obtained from said code signal generating means.

8. An electronic controlled heat cooking apparatus in accordance with claim 7, which further comprises operation detecting means for detecting an operation of said displaceable entry means included in said timer time period entry means, and wherein

said timer time period storing means stores said timer time period based on said code signal obtained from said timer time period entry means upon detection of an operation by said operation detecting means.

9. An electronic controlled heat cooking apparatus in accordance with claim 8, wherein said operation detecting means comprises displacement detecting means for detecting displacement of said displaceable entry means.

10. An electronic controlled heat cooking apparatus in accordance with claim 8, wherein

said displaceable entry means is structured to maintain the position to which it is displaced after the displacement operation is completed.

11. An electronic controlled heat cooking apparatus in accordance with claim 8, which further comprises

timer time period information display means responsive to the output of said operation detecting means for displaying timer time period information presently set by displacement of said displaceable entry means.

12. An electronic controlled heat cooking apparatus in accordance with claim 11, wherein

said timer time period information display means is used commonly by said timer time period entry means in said sections, and wherein said common timer time period information display means displays information set by said timer time period entry means last operated, upon detection of the operation last made of said displaceable entry means of said timer time period entry means by means of said operation detecting means.

13. An electronic controlled heat cooking apparatus in accordance with claim 2, wherein

said common timer time period information display means displays a timer time period information corresponding to a heating mode being newly performed when said heating mode is begun in accordance with the order as stored in said storing means in the course of a cooking operation.
