Abstract

PURPOSE:To enable cakes or cookies to be cooked with only one key operation by a method wherein a heating pattern for heating cakes and another heating pattern to bake cookies are automatically recognized during a cooking operation and then the cooking is carried out. CONSTITUTION:A cooking device comprises a turn table 9, a square pan 11 removably arranged in the turn table, an upper heater 7, a lower heater 8, the first temperature heater 15 for sensing a temperature within a heating chamber and the second temperature sensor 16 for use in sensing a temperature within the heating chamber near a position where the square pan 11 is disposed. Presence or non-presence of installation of the square pan 11 into the heating chamber is judged by a control part according to the difference between the first and second temperature sensors 15, 16 at the beginning of cooking operation. When the presence of the square pan is judged, a subsequent controlling heating pattern for use in cookie cooking with the square pan 11 is determined. In addition, when non-presence of the square pan is judged, a subsequent heater controlling pattern for use in cooking cake with the turn table 9 is determined. Accordingly, a cooking can be carried out by one key operation through a keyboard and its operating characteristics can be improved.

In each configuration, for example, a heating pattern for heating cakes on the turntable and a heating pattern for mounting cookies on the food placing body near the center of the heating chamber to cook cookies are cooked. Automatically identify and execute on the way. Thereby, cooking of cakes and cookies can be performed based on one key operation, and operability is good.

[0007]

EXAMPLE FIG. 1 shows the structure of a microwave oven according to an example of the present invention. A keyboard 2 is provided on the front surface of the microwave oven main body 1. The keyboard 2 has an automatic cooking key such as a candy key 3 and a start key 4.

Inside the microwave oven main body 1, a heating chamber 5, a cooking magnetron 6 for supplying microwaves to the heating chamber 5, and a cooking chamber mounted on the upper and lower walls of the heating chamber 5 are provided. Upper and lower heaters 7 and 8, a turntable 9 arranged in the lower part of the heating chamber 5, a motor 10 for rotationally driving the turntable 9, and a detachable part near the center of the heating chamber 5. A food placing body, that is, a metal square plate 11,
Receiving portions 13 and 13 that are pressed against the side wall 12 of the heating chamber to support the square plate 11, a first temperature sensor 15 attached to the upper wall 14 of the heating chamber 5 for detecting the temperature in the heating chamber, and the square plate. A second sensor mounted on the side wall 12 of the heating chamber in the vicinity of the arrangement position of 11, that is, in the vicinity of the receiving portion 13 for detecting the temperature in the heating chamber
A temperature sensor 16 is provided.

FIG. 2 shows a block circuit of the microwave oven. A control unit 17 including a microcomputer for controlling the microwave oven is provided. Around the control unit 17, the keyboard 2, the magnetron 6, the upper and lower heaters 7, 8, the first and second temperatures are provided. Sensor 15,
16 and a turntable motor 10 are arranged. The control unit 17 inputs the key operation information from the keyboard 2 and the room temperature information from the first and second temperature sensors 15 and 16, and in order to execute cooking, the magnetron 6 and above,
The lower heaters 7 and 8 and the motor 10 are drive-controlled.

FIG. 3 shows the flow of the sweets program incorporated in the control unit 17, and the operation of the microwave oven will be described in detail below with reference to this figure.

When the confectionery key 3 and the start key 4 are operated on the keyboard 2, the control section 17 starts driving the upper and lower heaters 7 and 8 in order to start the confectionery cooking (S).
1 step). Then, when 5 minutes have passed after the start of cooking in the initial stage of sweets cooking (S2 step), the first and second
The difference between the temperatures t1 and t2 detected by the temperature sensors 15 and 16 (t1
It is determined whether -t2) is 15 [deg.] C. or higher (S3 step; corresponds to the food placing body determination means of the present invention).

Then, a square plate 11 is provided near the center of the heating chamber 5.
When the cookie dough is lined up on the square plate 11 to bake the cookie, the heat in the heating chamber near the square plate 11 is taken by the square plate 11 and the temperature rising speed in the vicinity of the arrangement position of the square plate 11 is slow, The temperature detected by the second temperature sensor 16 is considerably lower than the temperature detected by the first temperature sensor 15, and the difference (t
1-t2) becomes 15 ° C. or higher, and an affirmative determination is made in step S3, which means that the square plate 11 is present.

According to the above determination, the oven temperature of 170 ° C. and the time of 17 minutes are automatically identified and determined as the heating pattern for the subsequent heater control for cooking cookies using the square plate 11. The drive control of the upper and lower heaters 7 and 8 is started for 17 minutes so that the temperature detected by the 1 temperature sensor 15 is maintained at 170 ° C. (S4 step;
Pattern determining means or first pattern determining means of the present invention). When 17 minutes have passed (S5 step), the driving of the upper and lower heaters 7 and 8 is stopped and the cooking of the candy (cookie) is completed (S6 step).

On the other hand, when the dough of the sponge cake is placed on the turntable 9 without using the square plate 11 and the cake is baked, since the square plate 11 is not provided, the temperature detected by the second temperature sensor 16 and the first temperature sensor 15 are not changed. There is no great difference from the detected temperature, the difference (t1−t2) is less than 15 ° C., and a negative determination is made in step S3, which means that the square plate 11 is not present.

When such a judgment is made, as a heating pattern for subsequent heater control for cake cooking using the turntable 9, the oven temperature is 160 ° C. and the time is 3 hours.
5 minutes is automatically identified and determined, and driving control of the upper and lower heaters 7, 8 is started for 35 minutes so that the temperature detected by the first temperature sensor 15 is maintained at 160 ° C. (S7 step; The pattern determining means or the second pattern determining means of the present invention). When 35 minutes have passed (step S8),
The driving of the lower heaters 7 and 8 is stopped and the cooking of the confectionery (cake) is finished (step S6).

[0016]

According to the present invention, for example, a heating pattern for heating cakes on a turntable and a food placing body mounted near the center of the heating chamber and baking cookies on the food placing body. The heating pattern can be automatically identified and executed in the middle of cooking, so that the cooking of cakes and cookies can be easily executed based on one key operation, and the operability of the cooker can be improved.
