DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a rotary cooker capable of rotating a pan heated by induction heating to automatically produce a stir-fry or the like.

[Related Art] Recently, with the advancement of technology for heating a magnetic pot by induction heating, a rotary cooker has been developed which rotates a pot by induction heating to automatically produce a stir-fry or the like. JP 63-1753
The electromagnetic cooker disclosed in Japanese Patent Publication No. 75 shows one example, and FIG. 4 is a partial side sectional view of the cooker.

In the figure, a cooking container 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. At the center of the cooking vessel 2, a pan 7 is rotatably disposed from the bottom by a driving device 8 via a shaft 9. At the periphery of the pan 7, an induction heating coil 6 is disposed via a heat insulating material 5. Has been established. A lid 10 is screwed on the upper portion of the cooking vessel 2 and a slip ring 11 is interposed between the lid 10 and the pot 7 so that the material in the pot 7 does not spill into the cooking vessel 2. Considered. A small lid at the center of the upper part of the lid 10 is for adding seasonings and the like.
There are twelve. Reference numerals 13 and 14 denote rotating speed, heating temperature or heating time adjusting sections, 15 a housing for housing the heat insulating material 5 and the induction heating coil 6, and 16 a cooking material.

When cooking the stir-fry, for example, using the above-mentioned electromagnetic cooker, the cooking vessel 2 is tilted to a desired angle by the support member 4, the drive device 8 is operated to rotate the pan 7, and the induction heating coil is rotated. After heating the outer periphery of the pan 7 by supplying electricity to the pan 6, the oil is poured into the pan 7, and when the oil is evenly attached to the pan 7, the rotation is stopped and the cooking material 16 of the stir-fry is put,
When the cooking material 16 is heated and rotated in the pan 7, the cooking material 16 is stirred and fried. 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.

Conventional electromagnetic cookers are configured and used as described above.

[Problem to be Solved by the Invention] In the conventional electromagnetic cooker as described above, the induction heating coil 6 for induction heating the pan 7 in which the cooking material 16 is placed is arranged on the bottom surface and the outer peripheral portion of the side surface of the pan 7, The bottom and side surfaces of the pot formed as described above are simultaneously induction-heated.
However, depending on the type of cooking, for example, heating only from the bottom of the pan 7 such as grilled meat is preferable,
In some cases, heating only from the side of the pot 7 is convenient, such as stewing curry or stew. Of course, some dishes, such as stir-fries, require simultaneous heating from the bottom and sides. As described above, in the conventional electromagnetic cooker, the heating method cannot be changed depending on the cooking method.

The present invention has been made in order to solve the above-described problems, and aims to provide a rotary cooker capable of simultaneously inductively heating a bottom surface or a side surface or a bottom surface side of a pot according to various cooking methods. It is.

[Means for Solving the Problems] A rotary cooker according to the present invention is a rotary cooker including a pot for storing cooking materials, a rotary drive device for rotating the pan, and a heating unit for induction heating the pan. A heating means comprising a first coil and a second coil which are arranged on the bottom and side surfaces of the pot and which are individually input-controlled, and a magnetic body which is induction-heated by the first coil and the second coil has a bottom surface, a side surface or a whole surface And a plurality of types of pans provided in the pan, so that these pans can be selectively used depending on the type of cooking.

[Action] A plurality of types of pots having a magnetic body portion induction-heated by the first coil and the second coil provided on the bottom surface, the side surface, or the entire surface are selectively used in accordance with the type of cooking, so that the cooking is performed. The induction heating of the magnetic part of the pot suitable for cooking can be performed efficiently.

Embodiment FIG. 1 is a side view of a pot according to an embodiment of the present invention.
FIG. 2 (a) shows a case where a magnetic portion is provided only on the bottom surface, FIG. 2 (b) shows a case where a magnetic portion is provided only on the side surface, and FIG. FIG. 3 is a sectional view showing a heating mechanism of the rotary cooker. In the figure, 7 is a pot, 20 is a magnetic part, 21 is a non-magnetic part, 30 is a first coil, 31 is a second coil, 32 is a first coil input control device, and 33 is a second coil input control device. is there. In addition, the rotation drive means of the pan 7 is omitted.

As shown in the figure, the heating means of the rotary cooker is divided into a first coil 30 for inductively heating only the bottom surface of the pan 7 and a second coil 31 for inductively heating only the side surface thereof. The input is individually controlled by the control device 32 and the second coil input control device 33, respectively. Note that the first coil input control device 32 and the second coil input control device 33 are
When the pot 7 with a limited length is inserted, the current to the first coil 30 or the second coil 31 corresponding to the non-magnetic member 21 is cut off, and the first coil 30 or the second coil 30 corresponding to the magnetic member 20 is cut off. Only the coil 31 is energized. In this case, the current flowing through the first and second coils 30 and 31 is detected by the current detecting means used in a general electromagnetic induction heating cooker, and when the current flowing through the coils is a small current, the current is detected. Since the portion of the pot corresponding to the coil is the non-magnetic portion 21, the current of the coil is cut off. Therefore, when the magnetic part 20 of the pan 7 is a pan 7 existing in a limited small area outside the range shown in FIG.
There is a possibility that the current of 30, 31 will be cut off. In such a case, the small object detection circuit shown in FIG. 3 may be introduced.

FIG. 3 is a small object detection circuit diagram, in which 40 is a power supply, 41 is an input detection element, 42 is a rectifier circuit, 43 is a level detection circuit, 44 is a variable resistor, 45 is a self-holding circuit, and 46 is an inverter circuit. ,
47 is an oscillation circuit, 48 is an inverter device, 49 is an input adjustment coil, 50 is a timer motor, 51 is a timer motor switch,
52 is a normally closed switch.

In such a small object detection circuit, when the normal pot 7 is placed on the first or second coil 30, 31, the input power is large, and the outputs of the input detection element 41 and the rectification circuit 42 are also large. The level detection circuit 43 does not emit a signal, so the self-holding circuit 45 does not operate and the first
Alternatively, the output to the second coils 30, 31 is continued. However, small items such as knives other than the pan 7 may be the first or second coil 3
If placed above 0.31, input sensing element 41 and rectifier circuit
Since the output of 42 is small, the level detection circuit 43 emits a signal, so that the self-holding circuit 45 operates to stop the operation of the oscillation circuit 47, stop the output of the inverter circuit 46, and stop heating of the small items.

When warming small items such as canned beverages, if the timer motor switch 51 is turned on, the timer motor 50 starts and the normally closed switch 52 is turned off to shut off the output of the self-holding circuit 45. Since the oscillation of the oscillation circuit 47 is not hindered and the output of the inverter circuit 46 does not stop, the canned beverage can be heated. That is, even if it is a small object, heating can be performed by providing the small object detection circuit shown in FIG.

In the embodiment configured as described above, since the magnetic body portion 20 to be induction-heated is limited by the pan 7, when heating only from the bottom surface such as grilled meat is preferable, FIG. When it is preferable to use the pan 7 shown in FIG. 1 and heating only from the side such as stewing curry or stew, use the pan 7 shown in FIG. When simultaneous heating from above is preferable, the pan 7 shown in FIG. 1 (c) is used. In this way, each pot 7 is selectively used according to the type of cooking, and cooking is performed efficiently.

[Effects of the Invention] As described above, the rotary cooker according to the present invention is a rotary cooker including a pot that stores cooking ingredients, a rotation drive device that rotates the pot, and a heating unit that induction-heats the pan. A heating means comprising a first coil and a second coil which are arranged on the bottom and side surfaces of the pan and are individually input-controlled,
A plurality of types of pots are provided on the bottom surface, side surface, or entire surface of the magnetic body portion that is induction-heated by the coil and the second coil, and these pots can be selectively used depending on the type of cooking. Therefore, the type of pot can be changed according to the cooking content, and cooking can be performed most efficiently.
