(Embodiment 1)
FIG. 1 is a side sectional view showing a power feeding device and an impeller according to Embodiment 1 of the present invention.
A cooking container 1 shown in FIG. 1 is a container in which to-be-cooked items such as ingredients are placed, and is a pan, a frying pan, or the like, and is placed above the power feeding device.

  The impeller 2 includes a power receiving coil 3 and a main body 6 that houses a power supply unit 4. The impeller 2 is housed in the cooking container 1 so as to be storable, and moves the cooking object by freely moving in the cooking container 1, and is movable as a blade so that the cooking object can be moved more easily. Part 7. And it becomes possible to stir a to-be-cooked object by moving a to-be-cooked object by the movable part 7. FIG.

  The power receiving coil 3 is magnetically coupled by facing the power feeding coil 8 forming the power feeding device, and can receive a high frequency magnetic field generated in the power feeding coil 8. The receiving coil 3 generates an electromotive force due to the high-frequency magnetic field received by the receiving coil 3. However, since the electromotive force varies depending on conditions such as the distance between the feeding coil 8 and the receiving coil 3, it is difficult to say that the power is stable. Therefore, if the load is a heater or the like, the operation does not change much. However, if the load is a motor or the like, the behavior of the load varies depending on the magnitude of the electromotive force generated in the power receiving coil 3 such as the number of revolutions. It changes a lot. In that case, since the operation sound is heard in a undulating manner, there arises a problem that the user determines that it is a malfunction.

  In order to avoid such a phenomenon, the power supply unit 4 receives the electromotive force generated in the power receiving coil 3 and outputs it as stable power. Specifically, the power supply unit 4 is a circuit that can supply a constant voltage or current. By doing so, the operation of the load is stabilized and control is facilitated. Depending on the load, it may be output as a direct current.

  The power feeding coil 8 of the power feeding device is connected to the inverter unit 9, generates a high frequency magnetic field by flowing a high frequency current supplied from the inverter unit 9, and supplies power to the power receiving coil 3. The inverter unit 9 is controlled by the control unit 10 in terms of conduction ratio, frequency, and the like, and the high-frequency current supplied to the feeding coil 8 is controlled.

  The operation and action of the impeller configured as described above will be described below.

When the user instructs the start of power feeding by an operation unit (not shown), the control unit 1 of the power feeding device.
0 operates the inverter unit 9 to supply a high-frequency current to the feeding coil 8. As a result, a high frequency magnetic field is generated from the feeding coil 8, and an electromotive force is generated in the receiving coil 3.

  The control part 10 controls the inverter part 9 so that it may become the electric power supply amount which the user set when the user operates the operation part. Specifically, for example, the input current of the inverter unit 9 is detected, and the detected value is input to the control unit 10. The control unit 10 compares the power supply amount set by the user with the input current of the inverter unit 9 and changes the operation state of the inverter unit 9.

  With such an operation, the power set by the user is supplied to the impeller 2. When it is not necessary to change the power supply amount, for example, when the power consumed by the impeller 2 is determined in advance, the control unit 10 may control the inverter unit 9 so that predetermined power is supplied.

  The electric power supplied in this way is consumed in the impeller 2. Specifically, the object to be cooked in the cooking container 1 is moved by moving the impeller 2. By doing so, since the to-be-cooked object does not stay in the same place in the cooking container 1, for example, it can prevent that the to-be-cooked object burns. In addition, the movement of the food to be cooked brings benefits such as mixing of the food to be cooked and a uniform taste.

  Here, although the operating temperature of the battery normally used is about 45 to 65 ° C., in the present embodiment, since the battery is not used, the problem is that the battery deteriorates due to the high temperature inside the cooking container. Disappears.

  As described above, with the configuration of the present embodiment, power can be supplied from the external power supply device to the impeller 2, so that no battery is used and there is no fear of running out of the battery. Therefore, it is possible to use the load built in the impeller 2 without being restricted by the use time and the use temperature, and it is possible to provide an impeller that can shorten the cooking time and improve the finishing of cooking. Moreover, since the impeller 2 of this Embodiment is comprised so that attachment or detachment is possible at the time of accommodation with respect to the cooking container 1, it becomes a structure which is easy to store and is easy to use.

  In the present embodiment, the impeller 2 is connected to the power receiving coil 3 or the power supply unit 4 and has a configuration in which the main body 6 includes a motor 5 that is driven by receiving power supply.

  The motor 5 may be a DC motor or an AC motor. In the case of an AC motor, the electromotive force generated in the power receiving coil 3 can be used as it is. However, as described above, the influence of the electromotive force generated in the power receiving coil 3 is reflected in the operation as it is. Operation may not be stable. In addition, since the rotational speed is determined by the frequency of the electromotive force, switching of the capacitor or the like is required to change the rotational speed.

  On the other hand, in the case of a direct current motor, the generated electromotive force needs to be converted to direct current, and therefore it is necessary to be connected via the power supply unit 4 without fail. After the electromotive force is converted to DC by the power supply unit 4, the rotational speed of the DC motor can be changed by controlling the voltage.

  When these motors 5 are driven, the impeller 2 itself is used to rotate or move. Thereby, the to-be-cooked object which existed around the impeller 2 moves, and can prevent burning. Furthermore, since the effect of stirring is obtained by moving the object to be cooked, the effect of uniforming the taste of the object to be cooked, making the way of the fire uniform, and the effect of shortening the cooking time Is obtained.

In order to make the impeller 2 easier to move, a vibration motor having an asymmetrical weight with respect to the shaft of the motor 5 may be used. By doing so, it is possible to widen the range in which the impeller 2 itself can move by simply driving the motor 5.

This embodiment will be described in further detail below with reference to the drawings.
2A and 2B are a side sectional view and a top view showing the impeller according to the first embodiment of the present invention. FIG. 2A is a side sectional view, and FIG. 2B is a top view. FIG. 3 is a side sectional view showing the main body and the movable part of the impeller according to the first embodiment of the present invention. FIG. 3A is a side sectional view showing a state in use in which the main body 6 and the movable part 7 are combined. FIG. 3B is a side sectional view showing only the main body, and FIG. 3C is a side sectional view showing only the movable part.

  2 and 3, the main body 6 includes a power receiving coil 3, a power supply unit 4, and a motor 5. These are components necessary for driving the impeller 2, and are not arranged to move inside the cooking container 1, and are disposed in the main body 6.

  On the other hand, the movable portion 7 is disposed so as to cover the outer periphery of the main body 6, and is fixed to the output shaft 5 </ b> A by fitting the output shaft 5 </ b> A of the motor 5, and the movable portion 7 rotates when the motor 5 is driven. Configured to do. At that time, when the main body 6 is not fixed, a reaction force torque acts and the torque of the movable portion 7 falls. Therefore, it is desirable that the main body 6 is fixed to something. In addition, the movable part 7 has a plurality of blades 7 </ b> A extending substantially radially on the outer periphery.

  FIG. 4 is a perspective view showing a cooking container to which the main body of the impeller according to the first embodiment of the present invention is attached, and a mounting portion 11 protruding in a rectangular shape is provided at the bottom of the cooking container 1. A rectangular opening (not shown) corresponding to the attachment portion 11 is formed on the bottom surface of the main body 6 of the impeller 2, and both are configured to be fitted to each other. By attaching the main body 6 to the attachment portion 11, the reaction force torque can be suppressed and the output torque of the motor 5 can be transmitted to the movable portion 7 without loss, so that the torque of the movable portion 7 increases. By doing so, the cooking object can be moved even when there are many cooking objects in the movable part 7 or when the viscosity of the cooking object itself is high, so that the usable range is widened. The positional relationship between the main body 6 and the movable portion 7 may be such that the main body 6 may be disposed outside the movable portion 7 in addition to the movable portion 7 being disposed outside the main body 6 as shown in FIG. The structure by which the movable part 7 is arrange | positioned at the upper part of the main body 6 may be sufficient.

  However, an impeller that is as small as possible does not consume space in the cooking container, and can cook a large amount of food. In order to design the main body 6 of the impeller small and further maximize the torque, it is desirable that the movable portion 7 be disposed outside the main body 6.

  The impeller 2 of the present embodiment includes a main body 6 and a movable portion 7 that is movable with respect to the main body 6 fixed to the cooking container 1. The main body 6 includes a power receiving coil 3, a power supply portion 4, and the like. The motor 5 is provided, and only the movable part 7 is movable when the motor 5 is driven.

A method of using the impeller 2 configured as described above will be described below.
The main body 6 is fixed by being attached to an attachment portion 11 at the bottom of the cooking container 1. The movable part 7 is fitted to the output shaft 5 </ b> A of the motor 5 in the main body 6 and is arranged so that the output of the motor 5 is transmitted to the movable part 7.

  The cooking container 1 is placed on a power feeding device in which an object to be cooked is placed. At that time, it is necessary to place the feeding coil 8 and the receiving coil 3 so that they face each other and are magnetically coupled.

The user inputs a power supply instruction by operating the power supply apparatus, and the control unit 10 controls the inverter unit 9 based on the instruction. The inverter unit 9 causes a high-frequency current to flow through the power supply coil 8 while controlling the conduction ratio and frequency by the control unit 10, and a high-frequency magnetic field is generated in the power supply coil 8. The receiving coil 3 receives the magnetic field to generate an induced electromotive force, and the electric power is supplied to the motor 5 through the power supply unit 4. When the motor 5 is driven, the movable portion 7 attached to the output shaft 5A of the motor 5 is moved, and the food to be cooked around the impeller 2 is moved.

  If the impeller 2 does not move, the object to be cooked remains in the same place because there is no movement other than convection in the cooking container. If heating is continued as it is, the cooked food will burn into the cooking container. Moreover, since the food is not mixed, the taste and temperature are not uniform. For this reason, it is usually necessary for the user to perform operations such as stirring.

  However, in the present embodiment, since power can be supplied from the power supply apparatus to the motor 5 that is a driving source, the impeller 2 can be replaced by moving the impeller 2 without performing the act of stirring the user. Therefore, the user can do other cooking work and there is no worry about burning. Further, since the taste and temperature are uniform, it is possible to provide the benefits that the finish is good and the cooking time is short.

  The feeding device may heat the cooking container, or the cooking container may be induction-heated by a high-frequency magnetic field generated from the feeding coil 8. In that case, the cooking container needs to be a metal that can be induction-heated. Moreover, the control part 10 may be the same, and may change the drive frequency of the inverter part 9 at the time of electric power feeding and at the time of a heating.

FIG. 5 is a plan view of the induction heating apparatus in which a large number of power supply coils are arranged in a matrix form immediately below the top plate constituting the outline of the induction heating apparatus according to Embodiment 1 of the present invention.
In the induction heating apparatus shown in FIG. 5, the case where the cooking container 1 is mounted on the nine power supply coils 8a to 8i as shown in FIG. When the attachment portion 11 is in the center of the bottom portion of the cooking vessel 1, the power receiving coil 3 disposed in the main body 6 of the impeller 2 is opposed to the power feeding coil 8a and is magnetically coupled. Therefore, when the impeller 2 is moved, the controller 10 may supply power to the impeller 2 by supplying a high-frequency current to the power supply coil 8a. On the other hand, the cooking container 1 is heated by the control unit 10 supplying a high-frequency current to any one of the feeding coils 8a to 8i. At that time, heating and power feeding may be performed simultaneously, or only one of them may be performed. By controlling in this way, heating of the cooking container 1 and movement of the food by the impeller 2 can be performed freely.

  As described above, an impeller according to the present invention includes a main body that is movably disposed in a cooking container, and the main body includes a power receiving coil that is magnetically coupled to a power feeding coil of a power feeding device. By having a power supply unit that can input power generated by receiving a magnetic field generated by the power supply coil of the power supply device, the object to be cooked is moved by moving the impeller using the power supplied from the power supply device. It becomes possible to make it. Furthermore, since the taste becomes uniform and the cooking time can be shortened, it has the effect of automating cooking and minimizing power consumption, and is useful when used in general households.
