Abstract

PURPOSE:To make it possible to easily store the most suitable heat-cooking period of time for a food and the output level of the heating unit. CONSTITUTION:A processing circuit 6 drives a heating unit, which consists of a micro-wave generating source 8 or an electric heater 11, by controlling an inverter circuit or switching circuit 10, to heat-cook a food in a heat-cooking chamber 3. A timer 13 which is built in the processing circuit 6 counts the actual heat-cooking period of time. An input unit 7 indicates the writing of the actual heat-cooking period of time by the timer 13 at the point when the food in the heat-cooking chamber 3 has reached the best finish condition and the heat-cooking has been stopped, and the output level of the heating unit to RAM, by pressing, e.g. a 'memory 1' key. By this method, the best heat- cooking period of time for a food and the output level of the heating unit can be stored by a simple process.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of a heating and cooking device such as a microwave oven.

[0002]

2. Description of the Related Art A microwave oven, which is one of cooking devices for heating food, supplies AC power from a commercial AC power supply to a magnetron through an inverter circuit or the like,
The high frequency microwave generated by this magnetron is used to dielectrically heat the food. The heating time and the output level of the magnetron at that time are set by the user according to the food or cooking menu.

Conventionally, a microwave oven has a storage unit for storing the heating time of foods that are frequently cooked and the output level of the magnetron. Then, when the heating time and the output level are stored in this storage unit, the following is performed. That is, first, the setting contents are determined with reference to the cooking book attached to the microwave oven, and key input is performed from the input unit to temporarily store the setting contents. Then, the food is actually cooked by the temporarily stored heating time and the output level, and the user updates the stored contents by the input unit in preparation for the next cooking depending on the finish.

Alternatively, while actually heating and cooking, the finish condition is monitored, and when the finish condition desired by the user is reached, the microwave oven is stopped. Then, the user calculates the actual heating and cooking time at that time, and the calculated actual heating and cooking time and the output level are input from the input unit and stored in the storage unit.

[0005]

However, when the optimum heating time of the food that is frequently cooked and the optimum output level of the magnetron are stored in the storage section of the microwave oven as described above, the user temporarily stores them. There is a problem that it is very troublesome to look at the finished state of actual cooking with the heating time and the output level and to update the stored contents if it is inconvenient. Alternatively, the user can actually cook the target food using a microwave oven, find out the heating time and the output level at which the optimum cooking state can be obtained, and then find out the found optimum heating time and the optimum output level. There is a problem that it has to be stored in the storage unit, which is very troublesome.

SUMMARY OF THE INVENTION An object of the present invention is to provide a heating and cooking apparatus which can easily store the cooking time of food and the output level of the heating section in the storage section.

[0007]

To achieve the above object, the heating and cooking apparatus of the present invention is a heating and cooking apparatus for heating food by a heating section under the control of a control section. The time section that measures the actual power energizing time when actually cooking food and the designation of the power energizing value and power energizing time to the above heating section, or the food is actually cooked An input unit for instructing storage of the actual power energizing time and the actual power energizing value measured by the time counting unit, and the power energizing time and the power energizing value designated by the input unit, or the input It is characterized by comprising a rewritable memory in which the actual power energizing time and the actual power energizing value instructed to be stored by the unit are written by the control unit.

[0008]

The heating unit is energized according to the power energizing value and the power energizing time designated by the input unit to heat and cook the food. Then, the timer unit measures the actual power energizing time for the heating unit. In this way, the food is cooked, the user finally recognizes that the optimum finished state has been reached, and the cooking is stopped. When the input unit instructs the storage of the actual power energizing time and the actual power energizing value measured by the time counting unit, the control unit writes the actual power energizing time and the actual power energizing value in the memory. Be done. As a result, the memory automatically stores the optimum power energizing value and the optimum power energizing time for obtaining the optimum finish of the food.

Further, when the optimum power energizing value and the optimum power energizing time stored in the memory are changed due to a change in taste or the like, a new power energizing value or a new power energizing value from the input unit is changed. The contents of the memory are rewritten by inputting the power energizing time.

[0010]

The present invention will be described in detail below with reference to the embodiments shown in the drawings. FIG. 1 is a block diagram showing an embodiment in which the heating and cooking apparatus of the present invention is applied to a microwave oven. AC power is supplied from an AC power supply 1 such as a commercial AC power supply to a heating and cooking device 12 of a microwave oven via a breaker 2.

The heating / cooking device 12 is provided with a heating / cooking chamber 3 having a heating section composed of a microwave generator 8 realized by a magnetron or the like and an electric heater 11 using a sheath wire or the like. Then, the food put in the heating cooking chamber 3 is cooked by two heating means, that is, the dielectric heating by the high frequency microwave from the microwave generation source 8 or the heating by the electric heater 11. The electric power energizing value for the electric heater 11 is previously set to be constant. On the other hand, the power energizing value for the microwave generation source 8 is set to the value input from the input section 7 by the processing circuit 6.

The AC power supplied from the AC power supply 1 to the heating and cooking device 12 via the breaker 2 is supplied to the DC voltage generation circuit 4 and the inverter circuit 5 and the switch circuit 10. DC voltage generating circuit 4
Converts the given AC power into DC power and energizes the processing circuit 6. An input unit 7 is connected to the processing circuit 6, and via this input unit 7, setting / storing and calling of the cooking time of foods to be cooked frequently, instructions for executing cooking, input of cooking menu, microwave An instruction to supply the energizing power to the generation source 8 or the electric heater 11 is given.
The input section 7 is composed of various key switches,
It has keys such as "10 minutes", "1 minute", "10 seconds", "memory-1", "memory-2", "stop", "cancel" and "heat".

A display unit 9 is connected to the processing circuit 6, and the cooking time of the frequently-cooked food input from the input unit 7, the contents of the output level of the heating unit, the temperature inside the cooking chamber 3 are heated. Information such as cooking time and cooking time is displayed. Further, the processing circuit 6 gives a signal to the inverter circuit 5 and the switch circuit 10 to adjust the energizing power to the microwave generation source 8 or the electric heater 11.

The processing circuit 6 constituted by, for example, a microcomputer contains a ROM (read only memory), a RAM (random access memory) and a timer 13. In the ROM, in response to a cooking menu selected by an instruction from the input unit 7, the microwave source 8 and the electric heater 11 are used to control the cooking time, the cooking temperature, and the like for cooking food. Contains cooking programs. The cooking program stored in the ROM does not disappear even when the power supply to the processing circuit 6 is deenergized.

On the other hand, the RAM stores the cooking time of food that is frequently cooked, the output level of the microwave generator 8 or the electric heater 11, and the like. This stored content can be rewritten many times by input from the input unit 7. Further, the timer 13 counts the actual cooking time when the food is actually cooked.

The inverter circuit 5 converts the frequency of the AC power supply 1 into the order of gigahertz (GHz) and energizes the microwave generation source 8. The output voltage of the inverter circuit 5 at that time is adjusted by the signal from the processing circuit 6, and as a result, the energizing power of the microwave generation source 8 is set. The switch circuit 10 switches and sets whether or not to perform electric power energization of the electric heater 11 based on a constant electric power energizing value set in advance based on the AC power source 1 according to a signal given from the processing circuit 6.

That is, the processing circuit 6 constitutes the control section, and the timer 13 constitutes the time counting section.

FIG. 2 is executed by the processing circuit 6 when the RAM automatically stores the cooking time and the output level of the heating section for optimally cooking the above-mentioned frequently cooked food. 7 is a flowchart of a heating condition storage processing operation performed. Hereinafter, the heating condition storage processing operation will be described in detail with reference to FIG. This heating condition storage processing is performed when the user actually cooks the target food by the microwave oven, when the user determines that the optimum cooking state is reached and stops the microwave oven, the output level and the heating of the heating unit. The cooking time is automatically stored in the RAM. That is,

In step S1, the food that the user frequently heats and cooks (that is, the food whose RAM is to store the cooking time and output level) is put in the cooking chamber 3, and the "heating" key of the input unit 7 is pressed. It is pressed to start cooking. The output level of the microwave generation source 8 or the electric heater 11 at that time is set by the user based on experience, a cooking book, or the like in accordance with the target food. In step S2, the timer 13 of the processing circuit 6 starts counting the actual cooking time. In step S3, the user determines whether or not the cooked state of the food being cooked has been optimized. As a result, if it is in the optimum finished state, the process proceeds to step S4. If not, wait for the optimum finish.

In step S4, since the optimum finished state has been obtained, the user presses the "stop" key of the input section 7 to stop the cooking. In step S5, the counting of the actual cooking time by the timer 13 is stopped. In step S6, the above steps S1 to S5
The user determines whether or not to store the actual cooking time of the cooking performed by the processing up to and the output level. As a result, when storing, the input unit 7
The "memory-1" key or the "memory-2" key is pressed and the process proceeds to step S7. Otherwise, the heating condition storage processing operation is ended. In step S7, step S5
In RAM, the count value of the actual cooking time when the microwave oven is stopped and the value of the output level of the cooking performed are stored in the RAM. At this time, if the "memory-1" key of the input unit 7 is pressed in step S6, it is stored in the RAM for memory-1, and if the "memory-2" key is pressed, it is stored in the memory-2. It is stored in RAM.
Then, the heating condition storage processing operation ends.

As described above, according to this embodiment, the user presses the "stop" key of the input unit 7 when the optimum finished state is obtained when the user actually heats and cooks the food. When it is desired to store the actual cooking time and the output level of the heating unit in the internal memory RAM of the processing circuit 6 at this time, press the "Memory-1" key or the "Memory-2" key of the input unit 7. RAM for the cooking time and output level to obtain the optimum finished state with a very simple process.
Can be automatically stored in. That is, based on the cooking time and the output level that have been temporarily stored once, the finished state is actually confirmed and the stored contents are updated according to the user's preference, or the user himself / herself actually performs the cooking while cooking. There is no need to calculate the time.

The algorithm for the heating condition storage processing operation in the present invention is not limited to the algorithm shown in FIG. Further, in the above embodiment, the present invention has been described by taking a microwave oven as an example. However,
The present invention is not limited to this, and the present invention may be applied to other heating and cooking devices.

[0023]

As is apparent from the above, in the heating and cooking apparatus of the present invention, the actual power energizing time during actual heating and cooking of food is measured by the timekeeping section, and the food is brought to the optimum finished state. At this time, if the input unit instructs to store the actual power energizing time and the actual power energizing value at that time,
Since the control unit writes the actual power energizing time and the actual power energizing value in the rewritable memory, the actual power energizing time and the power energizing value at which the optimum finished state of the food can be actually obtained are extremely small. Can be easily stored in memory.

Further, since the control unit can write the power energizing time or the power energizing value input from the input unit to the memory, the power energizing time and the power energizing time stored in the memory are The power energization value can be easily rewritten.
