A cooking course setting device, 48 is a cooking condition setting device. Cooking course setting device 47 for cooking course 47 such as curry and stir fry
a to n (not shown) are input, and various cooking conditions 48a to n (not shown) such as an inclination angle and a rotation speed that influence the heating temperature and stirring of the cooking pot 7 are selectively selected by the cooking condition setting device 48. Keyed in.

As shown in FIGS. 1 to 3, the rotary cooking machine according to the present invention comprises a cooking pot 7, a rotary drive device 8 for rotating the cooking pot 7, and a cooking pot 7. A cooking container 2 including a heating coil 6 for induction heating, a tilting device 20 for tilting the cooking container 2, a brake 26 for holding a tilt angle, and an angle detection device 27.
And a control device 30 and the like.

Further, the rotary drive device 8 comprises a drive motor 8a and a drive train wheel 8b, and the heating coil 6 is provided in the housing 1.
It is housed in 5. Further, the tilting device 20 is mounted on the support base 3
The adjustment motor 21 mounted on the second gear 2, the first gear 22 axially mounted on the motor 21, and the second gear 23 meshing with the first gear 22. The bracket 24 fixed to the lower surface of the housing 15 is fixed to the second gear 23, and together with the second gear 23, the shaft 25 fixed to the support 32.
It is rotatably inserted. Therefore, when the motor 21 is operated, the gear trains 22 and 23 rotate, and at the same time, the bracket 24 rotates to tilt the cooking container 2. Further, the angle detecting device 27 for detecting the inclination angle of the cooking container 2 by the inclining device 20 includes an infrared transmitter 28 attached to the support 24 and a plurality of flag plates 29a to 29d attached to the bracket 24. And the flag plates 29a to 29d attached to the bracket 24 are the infrared transmitter 2
The signal emitted each time the light passes through 8 and blocks the infrared light is sent to the control device 30.

Since the inclination angle setting device for the cooking container 2 is constructed as described above, if the inclination angle of the cooking container 2 during cooking is preset by the cooking condition setting device, the motor 21 is activated. When the cooking container 2 is tilted, the angle detection device 27 functions at the set angle, the motor 21 is stopped, the brake 26 is operated, and the tilt is maintained at a predetermined angle. In addition, normally, after the input signal of the limit switch 33 is detected at the time of start so that the cooking pot 7 is in the horizontal position, the predetermined angle is detected by the number of flags that cross the infrared transmitter 28.

Further, the entire control device provided with the timer 43 is constructed as shown in FIG. 4. For example, programs of cooking steps of various cooking courses shown in the time charts of FIGS. 5 to 7 are provided. Formulated and built-in. Therefore, if the user of the cooking machine puts the cooking ingredients in the cooking pot, selects a desired course from the cooking courses 47a to 47n and inputs it to the input interface 40,
The desired dish is cooked automatically.

The operation of the cooking machine in the case of the stir-fry course shown in FIG. 5 will be described with reference to a time chart. In the case of stir-fried food, for example, when the diameter of the cooking pot 7 is 220 mm, the inclination angle θd and the rotation speed of 30 rpm are input by the cooking condition setting device. The cooking ingredients are put in the cooking pot 7, and the angle adjusting motor 21 is operated at time t0 to tilt the cooking container 2. When the predetermined tilt angle is θd, t1
When the inclination becomes θd, the angle adjusting motor 21 is stopped by the flag plate 29d of the angle detecting device 27 and the brake 26 is operated to keep the angle of the cooking pot at θd, and the driving motor 8a is turned on. While rotating the cooking pot by driving at a rotation speed of 30 rpm, the heating coil 6 is energized to heat the cooking pot 7. When the time t2 is reached after a predetermined time (t1 → t2) has passed, the timer 43 operates and the cooking pot 7
When the cooking container 2 is returned to the horizontal position by releasing the brake 26 and operating the angle adjusting motor 21 while stopping the rotation and heating of the cooking container 2, the angle detecting device 27 operates. The brake 26 is activated, the cooking container 2 is stopped at the initial position, and cooking is completed. Everything is automatically operated by the controller until cooking is completed from the tilt of the cooking container 2 and the cooking container 2 is returned to the horizontal position.

The operation of both courses shown in FIGS. 5 and 6 is a time chart when the cooking pot 7 is in the horizontal position at the start, but the case where the cooking pot 7 is not in the horizontal position will be described. . FIG. 7 is a time chart when the cooking pot 7 is slightly tilted at the start in the stir-fry course shown in FIG. The cooking ingredients are stored in the cooking pot 7,
Until the input signal of the limit switch 33 is detected, the inclining device 20 is operated so that the cooking pot 7 is in the horizontal position, and after the input signal of the limit switch 33 is detected, it is fried according to the program shown in FIG. Complete the course.

By the same operation, the curry or stew shown in FIG. 6 can be automatically cooked, and further other dishes can be cooked. However, in the stew course of FIG. 6, the inclination angle is 15 degrees and the rotation speed is 15 rp.
set to m. Further, in the cooking that shifts from frying to stewing, the cooking conditions are combined and set.

In this embodiment, an infrared sensor is used as the angle detecting device 27, but a magnetic sensor may be used. However, when using a magnetic sensor, it is better to stop energization to the heating coil while adjusting the angle of the cooking container in consideration of the influence of magnetic field lines from the heating coil. Alternatively, an encoder may be attached to the shaft 25 to detect the angle. Further, the angle adjusting mechanism is not limited to the gear mechanism shown in this embodiment, and a ball screw, a link, a cam mechanism or the like may be used. Moreover, although the case where the magnetic cooking pot is heated by the induction heating coil has been described, the present invention is also applicable to a cooking machine that heats the cooking pot by heating the heating wire.

[0021]

According to the present invention, there are provided a rotary drive means for rotating the cooking pot, a heating means for heating the cooking pot, an inclining means for inclining the cooking pot, a rotary drive means, a heating means and an inclining means. In a cooking machine having a control means for controlling and heating and tilting and / or rotating a cooking pot, the control means has a plurality of cooking program means for formulating cooking steps for cooking under cooking conditions according to a cooking course. Then, based on the cooking program means, a cooking machine for controlling the rotation driving means, the heating means and the inclining means is constructed.

Further, a rotation driving means for rotating the cooking pot, a heating means for heating the cooking pot, an inclining means for inclining the cooking pot, and a control means for controlling the rotation driving means, the heating means and the inclining means. In the cooking method in which the cooking pot is heated and tilted and / or rotated to cook, the control means tilts the cooking pot at a predetermined angle according to the cooking course such as frying, boiling, or cooking. And a plurality of cooking program means including a cooking step in which the cooking pot is heated while being driven by a predetermined number of revolutions, and the rotation driving means, the heating means and the inclining means are controlled based on the cooking program means. The cooking method of being cooked is adopted.

As a result, by programming the cooking steps for cooking under the cooking conditions according to the cooking course, the desired dish can be automatically cooked, which greatly saves the time and effort of the cooking machine. Will be greatly improved.
