DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rotary cooking machine that can automatically prepare stir-fried dishes by rotating a pot using induction heating.

BACKGROUND ART [0002] Recently, with the advancement of technology for heating magnetic pots using induction heating, rotary cooking machines have been developed that rotate the pot using induction heating and automatically make stir-fried dishes. JP-A-63-1
The electromagnetic cooking machine disclosed in Japanese Patent No. 75375 is an example thereof, and FIG. 4 is a partial side view thereof.

In the figure, a cooking container 2 is rotatably attached to a main body 1 incorporating a heating power source via a hinge 3, and is configured to be supported and fixed at a desired inclination angle by a support member 4. . The support member 4 consists of a first support lever 4b and a second support lever 4C connected by a pin 4a, and by tightening the pin 4a, the cooking container 2 can be supported and fixed at a desired angle. cooking container 2
In the inner central part, a pot 7 is arranged so as to be rotatable from the bottom via a shaft 9 by a drive device 8, and an induction heating coil 6 is arranged around the periphery of the pot 7 via a heat insulating material 5. There is. A lid 10 is screwed onto the top of the cooking container 2, and a slip ring 11 is interposed between the lid 10 and the pot 7 to prevent the material in the pot 7 from spilling into the cooking container 2. It is considered.

Further, a small lid 12 for putting in seasonings and the like is provided in the upper center of the lid. Note that 13 and 14 are adjustment units for rotation speed, heating temperature, or heating time, and 16 is a cooking material.

When using the above electromagnetic cooking machine to cook stir-fried food, for example, the cooking container 2 is tilted at a predetermined angle by the support member 4, and the drive device 9 is activated to rotate the pot 7 while coiling the induction heating coil. After heating the outer periphery of the pot 7 by applying electricity to the pot 7, put oil into the pot 7, and when the oil is evenly coated inside the pot 7, stop the rotation, add the stir-fry ingredients 16, and put the lid 1o.
When the ingredients 16 are rotated, the ingredients 16 are stirred and fried while being heated in the pot 7. Next, when the time is right, open the small lid 12, add the seasonings, adjust the taste, and the cooking of the stir-fry is complete.

A conventional electromagnetic cooking machine is constructed and used as described above.

Further, the control device equipped with the timer 43 is constructed as shown in FIG. 2, and has built-in programs for cooking procedures for various dishes shown in the time chart shown in FIG. 3. Therefore, the user of the cooking machine puts cooking ingredients into the pot,
By inputting a desired course of cooking from among the courses 47a to 47n into the input interface 40, the desired course of food is automatically cooked.

The operation of the cooking machine in the case of the stir-fry course shown in FIG. 3(a) will be explained using a time chart. Add cooking ingredients to pot 7 and wait for time t. The angle adjustment motor 21 is operated to tilt the cooking container 2. If the predetermined inclination angle is θd, the time t
When the inclination reaches θd after 1 elapse, the angle detection device 29d is activated to stop the angle adjustment motor 21 and operate the brake 26 to maintain the angle of the pan at θd, and also drives the pan rotation motor 8a. While rotating the pot, turn on the heating coil 6.
The pot 7 is heated by applying electricity to the pot 7. Then, for a predetermined time (1-1)
When time t2 has elapsed, the tie 1 743 is activated to stop the rotation and heating of the pot 7, and at the same time, the brake 26 is released and the angle adjustment motor 21 is activated to tilt the cooking container 2 in the opposite direction and start cooking. When the container 2 returns to the horizontal position, the angle detection device 27a functions and the brake 2
6 is activated, the cooking container 2 stops at the initial position, and cooking is completed. Everything from the tilting of the cooking vessel 2 until the cooking is completed and the cooking vessel 2 returns to the horizontal position is automatically operated by the control device.

Each course of operation shown in FIGS. 3(a) and (b)
Although this is a time chart when the pot 7 is in the horizontal position at the start, the case where the pot 7 is not in the horizontal position will be explained. Figure 3 (C
) is the pot 7 of the stir-fry course 47a shown in FIG. 3(a).
is not a horizontal position at the start. Cooking ingredients are stored in the pot 7, and the limit switch 33 is turned on.
The tilting device 20 is operated so that the pot 7 is in a horizontal position until the input signal of the limit switch 33 is detected, and after the input signal of the limit switch 33 is detected, the frying course is carried out according to the program shown in FIG. Become.

By similar operations, it is possible to automatically cook the curry and stew shown in FIG. 3(b), and it is also possible to cook other dishes.

In this embodiment, the angle detection device 27 may be an infrared sensor or a magnetic sensor. However, when using a magnetic sensor, it is better to stop energizing the heating coil while adjusting the angle of the cooking container in consideration of the influence of magnetic lines of force from the heating coil.

Alternatively, an encoder may be attached to the shaft 25 to detect the angle.

Further, the angle adjustment mechanism is not limited to the gear mechanism shown in this embodiment, and a ball screw, link, cam mechanism, etc. may also be used.

[Effects of the Invention] The present invention provides a rotary cooking machine which includes a rotational drive means for a cooking pot, an induction heating means for the cooking pot, and an inclination angle setting device for the cooking pot including an angle detection device. The configuration is such that the tilt angle of the cooking pot can be automatically selected according to the set program, so by programming the cooking process according to the type of food, the cooking process will automatically cook that food. Now you can save a lot of time and effort in cooking.
This greatly improves the usability of rotary cooking machines.
