Description

Description: TECHNICAL FIELD The present invention relates to a rotary cooker capable of rotating a pot containing cooking ingredients while heating the same and automatically cooking a stir fry or the like. is there.

[Related Art] Recently, with the advance of technology for heating a magnetic pot by induction heating, a rotary cooker that rotates a pot and automatically cooks a stir-fry or the like by induction heating has been developed. JP
The electromagnetic cooker disclosed in JP-A-63-175375 shows one example, and FIG. 2 is a side view showing a part of the electromagnetic cooker in cross section.

In the figure, a cooking vessel 2 is rotatably mounted via a hinge 3 on a main body 1 in which a heating power source is incorporated, and is configured to be supported and fixed at a desired inclination angle by a support member 4. . The support member 4 includes a first support lever 4b and a second support lever 4c connected by a pin 4a, and the cooking container 2 can be supported and fixed at a desired angle by tightening the pin 4a. In the center of the cooking vessel 2, a pan 7 is rotatably arranged from the bottom by a driving device 8 via a shaft 9 and an induction heating coil 6 is arranged around the pan 7 through a heat insulating material 5. Has been established. Cooking container 2
A lid 10 is screwed into the upper part of the container, and a slip ring 11 is interposed between the lid 10 and the pan 7, so that the material in the pan 7 is not spilled into the cooking container 2. I have. Also lid
In the center of the upper part of 10, a small lid 12 for adding a seasoning or the like is provided. Reference numerals 13 and 14 denote rotating speed, heating temperature or heating time adjustment sections, 15 a housing, and 16 a cooking material.

When cooking the stir-fry, for example, using the electromagnetic cooker, the cooking container 2 is tilted to a desired angle by the support member 4 and the drive device 8 is operated to rotate the pan 7 while inducing the induction heating coil. After heating the peripheral portion of the pan 7 by supplying electricity to the pan 6, put the oil in the pan 7 and stop the rotation when the oil adheres to the pan 7 evenly. When rotated, the cooking ingredients 16 are stirred and fried in the pot 7 while being heated. Then, open the small lid 12 at the appropriate time, put in the seasonings, and adjust the taste to complete the cooking of the stir fry.

[Problems to be Solved by the Invention] The conventional electromagnetic cooker as described above uses the pot 7 of the cooking vessel 2.
Rotation speed is constant and does not change during cooking. However, when the cooking container 2 is tilted and the pan 7 is rotated to cook a stir-fry or the like, it is better to change the rotation speed of the pan 7 than to keep it constant in order to increase the effect of the stir-fry.

The present invention has been made in accordance with the above idea, and it is an object of the present invention to provide a rotary cooker capable of changing a rotation speed during one rotation of a pan to improve a cooking effect.

[Means for Solving the Problems] A rotary cooker according to the present invention comprises a pot containing cooking ingredients,
A cooking vessel provided with a rotating mechanism for rotating the pot and a heating mechanism for heating the pot; and a cooking vessel tilting means for tiltably supporting the cooking vessel on the rotary cooker main body, and rotating the pot. The rotation mechanism is provided with rotation speed changing means for changing the rotation speed during one rotation of the pan.

[Operation] In the present invention, the rotation speed is changed during one rotation of the pan, and the movement of the cooking material in the pan also changes. This allows
The cooking ingredients are well mixed and the cooking effect is improved in the case of stir-fry etc.

FIG. 1A is a side view showing a part of the embodiment of the present invention in cross section, and FIG. 1B is an enlarged view of a main part thereof. In the figure, 2 is a cooking vessel, 6 is an induction heating coil as a heating mechanism, 7 is a pan, 20 is a rotation speed changing device, 31 is a cooking vessel inclining device, and these constitute a rotary cooking machine.

The rotation speed changing device 20 is composed of a pulley 23 mounted eccentrically on a shaft 22 of a motor 21, a pulley 24, a belt 25 hung between the pulleys 23 and 24, and a tension pulley 26, and rotates the pan 7 Drive wheels 29, 30 which are rotating mechanisms to drive
A pulley is mounted on the drive shaft 27 of the motor.

In the case of cooking using the rotary cooker configured as described above, the cooking vessel 2 including the pan 7 and the induction heating coil 6 which is a heating mechanism for heating the pan 7 is heated by the cooking vessel tilting device 31. The pan 7 is heated by the induction heating coil 6 while the pan 7 is rotated by a rotation mechanism including the rotation speed changing device 20 at a desired angle.

At this time, since the pulley 23 is eccentrically attached to the shaft 22, when the motor 21 is started, the pulley 23 rotates eccentrically, and the rotation speed of the pulley 24 changes during one rotation. Therefore, the pan 7 also rotates while changing the rotation speed during one rotation. As a result, the rotation speed of the pan 7 is not constant, and the cooking ingredients in the pan 7 are moved in a complicated manner, and the cooking ingredients are mixed well. In the case of a stir-fry or the like, a cooking effect that cannot be obtained by rotating and cooking at a constant speed can be enhanced.

Note that the rotation speed changing device 20 is not limited to the configuration as seen in the present embodiment, and the rotation speed of the motor 21 may be changed by another method, for example, the duty ratio control or the phase control.

Further, although the case of the induction heating coil 6 has been described as an example of the heating mechanism, other heating means may be used. In this case, the same effect can be obtained.

[Effects of the Invention] As described above, according to the present invention, the rotating mechanism for rotating the pan of the cooking vessel is provided with the rotation speed changing means for changing the rotation speed during one rotation of the pan. The cooking material in the pot moves in a complicated manner according to the change of the rotation speed, and the cooking material is well mixed, so that the cooking effect can be improved.
