DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a microwave oven will be described below with reference to the drawings. In FIG. 1, which schematically shows the configuration of a microwave oven, a plug 1 connected to a commercial AC power source is connected to a constant voltage circuit 3 via a power transformer 2, and the AC voltage stepped down by the power transformer 2 is regulated. The voltage is applied to the voltage circuit 3. The DC power waveform-shaped by the constant voltage circuit 3 is applied to a control section 4 as a control means and each circuit.

The secondary side of the power transformer 2 is connected to a time base signal circuit 5. The time base signal circuit 5 is configured to output a pulse signal based on the cycle of the commercial AC power supply, and outputs a pulse signal with a frequency of 50 Hz to the control unit 4 when the power supply frequency is 50 Hz, for example.

A time adjustment knob 8 is provided on the operation panel (not shown).
, a keyboard 9 and a liquid crystal display section 10 are provided,
The amount of rotation of the time adjustment knob 8 and the operating states of the clock key 11, calendar key 12, etc. provided on the keyboard 9 are output to the control unit 4. Furthermore, display contents corresponding to the display output from the control section 4 are displayed on the liquid crystal display section 10.

The inverter circuit 13 includes a switching element (not shown), and outputs a switching output from an output terminal when the switching element is turned on. The output terminal of this inverter circuit 13 is coupled via a high frequency transformer 14 to a high frequency heating circuit 15 which is a heating means mainly using a magnetron. is output.

The control section 4 is mainly composed of a CPU, and operates according to a program stored in a memory (not shown). The control section 4 includes a clock section 6 and a calendar section 7, and the clock section 6 and calendar section 7 perform timekeeping operations based on the input of pulse signals from the time base signal circuit 5. .

Next, the operation of the above structure will be explained. When the power is turned on, the clock section 6 and calendar section 7 of the control section 4 are reset, so initial values are set in the clock section 6 and calendar section 7.

That is, when the calendar key 12 of the keyboard 9 is operated as shown in FIG. 2, "1990" is displayed on the liquid crystal display section 10 as shown in FIG. 3, followed by a flashing display of "Year". be done. As shown in FIG. 2, when the time adjustment knob 8 is rotated, the number displayed on the liquid crystal display 10 increases or decreases depending on the amount of rotation.
If the current year is 1991, for example, when "1991" is displayed on the liquid crystal display 10 as shown in FIG. 3, the calendar key 12 is operated as shown in FIG.

Then, as shown in FIG.
``1'' is displayed, followed by a flashing ``month''. Therefore, if the current month is October, rotate the time adjustment knob 8 as shown in FIG. 2 to display "10" on the liquid crystal display 10 as shown in FIG. 2, operate the calendar key 12. As a result, as shown in FIG. 3, "October" and "01" are displayed on the liquid crystal display 10, followed by a flashing display of "Sunday".

If the current date is the 27th, rotate the time adjustment knob 8 as shown in FIG.
With the date displayed, the calendar key 12 is operated as shown in FIG. The above operations complete the setting of the current date, so the LCD display 1 will be displayed as shown in Figure 3.
The words "Clock display" will be displayed at 0 to prompt you to adjust the clock.

When the setting of the current year, month, and day is completed as described above, the clock key 11 is operated as shown in FIG. Then, as shown in FIG. 5, "12 am" is displayed on the liquid crystal display 10, followed by a blinking "hour". At this time, if the current time is in the 5 p.m. range, rotate the time adjustment knob 8 as shown in FIG. 4 to display "5 p.m." on the liquid crystal display as shown in FIG. In this state, the clock key 11 is operated as shown in FIG. Then, as shown in FIG. 5, "5 p.m." and "00" are displayed on the liquid crystal display 10, followed by a blinking "minute".

Then, as shown in FIG.
With the current time "5:15 p.m." being displayed on the liquid crystal display 10, the clock key 11 is operated as shown in FIG. The above operations complete the setting of the current time.

On the other hand, the control unit 4 inputs the current date "1991" by operating the calendar key 12 as described above.
When "October 27, 2017" is set, "1991" is stored in the year storage area of the calendar section 7, "10" is stored in the month storage area, and "27" is stored in the day storage area. Further, when the current time "5:15 p.m." is set by operating the clock key 11, the control section 4 stores "17:00 p.m." corresponding to 5 p.m. in the hour storage area of the clock section 6.
” is stored, and “15” is also stored in the minute storage area.

The control section 4 sequentially updates the stored contents of the clock section 6 and the calendar section 7 every time a pulse signal from the time base signal circuit 5 is input. That is, since the time base signal circuit 5 outputs a pulse signal with a period corresponding to the frequency of the commercial AC power supply to the control unit 4, the control unit 4 inputs 50 pulse signals when the power supply frequency is 50Hz. Now, the power frequency is 60
In the case of Hz, when 60 pulse signals are input, it is determined that one second has elapsed, and one is added to the second storage area of the clock section 6.

When the second memory area of the clock unit 6 reaches 60, the control unit 4 determines that one minute has passed, resets the second memory area, and adds 1 to the minute memory area. . Further, the control unit 4 has a minute storage area of 60 minutes.
When this happens, it is determined that one hour has passed, and the minute storage area is reset and 1 is added to the hour storage area.

As a result of updating the time storage area as described above,
When the hour storage area reaches 24, the control section 4 resets the hour storage area and updates the calendar section 7. That is, the control section 4 stores calendars for a plurality of years, and sequentially updates the day storage area, month storage area, and year storage area of the calendar section 7 according to the calendar. As a result of the above operations, the clock section 6 of the control section 4 stores the current time, and the calendar section 7 stores the current year, month, and day.

Furthermore, since the control section 4 displays the time stored in the clock section 6 on the liquid crystal display 10 when the current date is set as described above, the time that is displayed on the liquid crystal display 10 is You can know the current time by checking the current time.

[0025] Furthermore, when the calendar key 11 is operated,
The control unit 4 displays the current year, month, and day stored in the calendar unit 7 on the liquid crystal display 10 for 5 seconds. You can know the day.

Now, when the control unit 4 receives an instruction to cook by operating the keyboard 9, it turns on the inverter circuit 13 based on the current date stored in the calendar unit 7. The operation when milk is selected as the object to be heated and cooked will be explained below.

In the flowchart of FIG. 6 showing the operation of the control section 4, when milk is selected as the object to be cooked, the control section 4 proceeds from step S1 to step S2.
The current month stored in the calendar section 7 is read, and the milk heating time corresponding to that month is read. In other words,
The control unit 4 stores the heating time for each cooking object, and in this case, the heating time is set to a time depending on the season. Specifically, as shown in Figure 7, the heating time for milk is set to 200 seconds, which is the standard heating time, during the spring season from March to May and the autumn season from September to November, and from December to February. In the winter period until January, it is set longer than 200 seconds, and 6
During the summer season from March to August, the time is set to be shorter than 200 seconds.

Therefore, in step S4, the control unit 4 heats the milk for the heating time set as described above, so that the heated milk reaches the standard finishing temperature of 65° C. in the spring and autumn. In the winter, the temperature is higher than 65℃, and in the summer, the temperature is lower than 65℃.

In short, in the case of the above embodiment, the control section 4 drives the inverter circuit 13 based on the current month (season) stored in the calendar section 7, so that the food can be heated to a temperature suitable for the season. Can be done. Therefore, unlike the conventional method in which food is heated for a uniform heating time, food can be eaten at a temperature that corresponds to the season.

In the above embodiment, the heating time is set in a plurality of stages depending on the season, but instead of this, the heating time may be set in detail for each month.

Furthermore, instead of changing the heating time depending on the season, the heating output may be changed depending on the season.

Furthermore, the present invention may be applied not only to microwave ovens but also to oven grill ranges and the like.

[0033]

Effects of the Invention As is clear from the above description, the heating cooking device of the present invention is provided with a calendar section for storing the current month and day, and the control means allows the heating and cooking device to change the date and time stored in the calendar section. Since the amount of heating by the heating means is adjusted based on this, an excellent effect is achieved in that the temperature of the object to be heated can be appropriately controlled depending on the season.
