Description

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 heated by induction heating.

[Prior Art] Recently, with the advancement of technology for heating magnetic pots using induction heating, rotary cooking machines have been developed that rotate the pots 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. There is. 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 hinged to the top of the cooking container 2, and a slip ring 11 is interposed between Mlo and ja7.
Care is taken to prevent the ingredients inside from spilling into the cooking container 2.

Further, a small lid 12 for putting in seasonings and the like is provided in the upper center of the lid. In addition, 13 and 14 are rotation speed, heating temperature, or heating time adjustment parts, and 15 is the above-mentioned heat insulating material 5.
and a housing for housing the heating coil 6, and 16 are cooking materials.

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 8 is operated to rotate the induction heating coil 6 while rotating the w47. After applying electricity to heat the outer periphery of the pot 7, put oil into the pot 7, and when the oil is evenly coated inside the pot 7, stop rotating, add the stir-fry ingredients 16, and put the lid 1 on.
When the material 16 is turned and heated in the pot 7, it is stir-fried by being pressed with a finger. 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 rotary induction cooking machine is configured as described above.
And it is used.

[Problems to be Solved by the Invention] By the way, in the above-mentioned electromagnetic cooking machine, the heating coil 6 for heating the pot 7 in which the cooking forest ingredients are placed is arranged at the bottom and the outer periphery of the side of the pot, and is made of a magnetic material. It is configured to heat the bottom and side surfaces of the pot 7 at the same time.

By the way, depending on the type of cooking, it is preferable to heat only from the bottom, such as when grilling meat, but on the other hand, there are also cases where it is convenient to heat only from the side, such as when simmering curry or stew. Of course, there are some dishes, such as stir-fries, that require heating from the bottom and sides at the same time. However, in conventional rotary cooking machines, it was not possible to change the heating method using the 21 Tanuki method.

The present invention was made to solve the above-mentioned problems of conventional rotary cooking machines, and provides a rotary cooking machine that can heat only the bottom, only the sides, or the bottom and sides simultaneously according to various cooking methods. This is what I am trying to do.

[Means for solving the problem] In order to achieve the above-mentioned [1], in the rotary cooking machine according to the present invention, in addition to the pan made entirely of magnetic material, the magnetic material portion is made only at the bottom, only the side, or In addition to selectively using a pot limited to special parts, the heating coil is divided into a first coil that heats only the bottom of the pot and a second coil that heats only the sides, and each coil is equipped with an input control means. The corresponding heating coil was configured to be turned on or off depending on whether the magnetic material portion or the non-magnetic material portion was present.

[Operation] By using a pot with a limited magnetic material portion in the cooking machine as described above, only the magnetic material portion of the pot will be heated. Therefore, if you use different pots depending on the type of cooking, you can cook each type of food efficiently.

[Embodiment of the Invention] Fig. 1 is a cross-sectional view of a pot with limited magnetic parts showing an embodiment of the present invention, in which (a) shows only the bottom part, (b) shows only the side part, and (e) shows only the side part. Fig. 2 is a sectional view showing the heating mechanism of a rotary cooking machine in which the entire pot is made of magnetic material. 7 in the diagram is a pot, 20
2 is a magnetic body part, 21 is a non-magnetic body part, 30 is a first coil, 3
1 is a second coil, 32 is a first coil input control device, 33
is the second coil human control device.

As shown in the figure, the heating coil of the cooking machine is divided into a first coil 30 that heats only the bottom of the pot and a second coil 31 that heats only the side. The second coils 31 are each controlled separately by the two-manpower control means 33. The heating coil manual control devices 32 and 33 are such that when the pot 7 with the magnetic material portion limited is placed on the heating coil, the current to the heating coil corresponding to the non-magnetic material portion is cut off, and the magnetic material The configuration is such that only the heating coil corresponding to the section is energized.

Generally, in cooking machines that use electromagnetic induction heating, in order to prevent small items such as knives, forks, spoons, etc. from being heated when they are placed on the cooking machine, the current flowing through the heating coil is detected, and if the current is small, is equipped with a safety device that cuts off the current in the heating coil. Therefore, if the magnetic body part of the pot is limited and the magnetic body part becomes a small area, there is a risk that the safety device will be activated and the current of the heating coil will be cut off.

In order to avoid this, it is necessary to introduce the structure of the small object heating device disclosed in Japanese Patent Laid-Open No. 60-63892.

FIG. 3 is a circuit diagram of the above-mentioned accessory heating device, in which 40 is a power supply, 41 is a human power detection element, 42 is a rectifier circuit, 43 is a level detection circuit, 44 is a variable resistor, 45 is a self-holding device,
46 is an inverter, 47 is an oscillation circuit, 48 is an inverter device, 4 is a manual adjustment coil, 50 is a timer motor, 5
1 is a timer switch, and 52 is a normally closed switch.

In the third prisoner, when using a normal pot, the human power is large and the outputs of the human power detection element 41 and the rectifier circuit 42 are also large, so the level detection circuit 43 does not emit a signal, so the self-holding circuit 45 Inverter device 48 not working
The output to the heating coil 6 continues. However, if a small object other than a pot, such as a knife, is placed on the heating coil, the output of the human force detection element 41 and the rectifier circuit 42 will become smaller.
The level detection circuit 43 issues a signal, and therefore the self-holding circuit 45 is activated to stop the operation of the oscillation circuit 47, the output of the inverter circuit 46, and the heating of the small object.

When heating small items such as canned drinks, turning on the timer switch 51 starts the timer motor 50 and turns off the normally closed timer switch 52, cutting off the output of the self-holding circuit 45 and causing oscillation. Since the oscillation of the circuit 47 is not hindered and the output of the inverter circuit 46 is not stopped, it is possible to heat the canned beverage. That is, even small objects can be heated by being equipped with the above small object heating device.

Therefore, in the present invention, when using a pot with a limited magnetic part, this corresponds to the case where the magnetic part heats small objects in a small area, so the pot with a limited magnetic part is equipped with the above-mentioned small object heating device. Care must be taken to ensure that it is heated even if it is heated.

In the cooking machine according to the present invention, the magnetic part that receives induction heating is limited to the pot, so if you want to heat only from the bottom, such as when grilling meat, use the pot of (a),
When simmering curry or stew, etc., use pot (B) and heat only from the sides; for stir-frying, use pot (C) and heat from the bottom and sides at the same time. good.

[Effects of the Invention] The present invention provides a rotary cooking machine in which the heating coil is divided into a first coil that heats the bottom of the pot and a second coil that heats the side, each of which is equipped with an input control device, and a magnetic part By making it possible to selectively use a pot limited to the bottom or side, cooking can now be done most efficiently by changing the type of pot depending on the cooking content.
