It has. When a voltage of, for example, 100 V is generated in the power receiving coil 14 due to an electromagnetic induction action of the power feeding coil 23 described later, the power supply circuit 17 uses the voltage to control the first operation unit 16, the control circuit 18, and the first communication circuit 19. And a voltage of 100 V can be supplied to the lid heater 12 and the body heater 13.

  The control circuit 18 includes a heating coil 22, a body heater 13, and a rice cooker according to the type of rice such as white rice and brown rice, the cooked state (hard and soft) set for each rice, and the rice cooking menu such as rice cake and rice cooker. An operation mode for controlling the power of the lid heater 12 is set. When the rice cooking menu is selected by the first operation unit 16, the control circuit 18 selects and executes an operation mode corresponding to the rice cooking menu. The control circuit 18 generates control information (power control) for the heating coil 22 based on the operation mode, transmits the control information by radio waves from the first communication circuit 19, and a second communication circuit 25 described later. To receive. When the control voltage from the power supply circuit 17 is applied, the first communication circuit 19 transmits, for example, information (predetermined information) indicating that the cooking device 1 is placed by radio waves, and the second communication described above. The circuit 25 receives the signal.

  The heating device 21 described above is formed in, for example, a rectangular parallelepiped shape whose appearance is low, and an annular heating coil 22 that is a heating source is disposed below the mounting table on the top. Further, an annular feeding coil 23 is disposed outside the outer periphery of the heating coil 22 with the central axis of the heating coil 22 as the center. Also, a power supply circuit 24 connected to the heating coil 22 and the power feeding coil 23, a second communication circuit 25 disposed opposite to the first communication circuit 19 of the cooking apparatus 1, and an upper surface on the near side of the mounting table are provided. The second operation unit 26 having a liquid crystal display and a control circuit 27 are provided. Instead of the heating coil 22 described above, a radiant heater may be used as a heating source. Further, the communication circuit may be shared by the feeding coil 23.

  The aforementioned heating coil 22 is arranged so as to face the heat-resistant plate 4 provided at the bottom of the cooking apparatus 1. This heating coil 22 is used not only for the cooking apparatus 1 but also as a heating source such as a pot or a frying pan capable of induction heating. The power feeding coil 23 is disposed so as to be magnetically coupled to the power receiving coil 14 disposed at the bottom of the cooking apparatus 1. The second operation unit 26 is used when cooking with a device other than the cooking device 1 and is configured to be able to select a cooking menu such as “stir-fried food” or “fried food” and set the heating power. .

  The power supply circuit 24 is connected to an AC 200V power supply, and when a power switch (not shown) provided in the cooker 21 is turned on, a power supply unit that applies a voltage of 200V to the feeding coil 23, the heating coil 22 A DC power supply unit and an inverter unit for supplying a high-frequency current are provided. When the second communication circuit 25 receives a radio wave from the first communication circuit 19, the second communication circuit 25 extracts predetermined information, control information, and the like from the received radio wave and outputs them to the control circuit 27.

  The control circuit 27 is set with a cooking menu such as “stir-fried food” and “fried food” described above, and an operation mode for controlling energization of the heating coil 22 in accordance with the set heating power. Further, when the information extracted by the second communication circuit 25 is information notifying that the cooking device 1 is placed, the control circuit 27 invalidates the input of the operation signal from the second operation unit 26, and The control information based on the operation of one operation unit 16 is validated.

Next, the operation of the heating device and the cooking device of the cooking device configured as described above will be described.
When the power switch of the heating device 21 is turned on after placing the cooking device 1 on the heating device 21, the power supply circuit 24 of the heating device 21 operates the power supply unit to apply a voltage of 200 V to the power supply coil 23 and supply a current. Shed. At this time, a voltage of 100 V is generated in the power receiving coil 14 of the cooking apparatus 1 by electromagnetic induction action and applied to the power supply circuit 17. When a voltage of 100 V is applied, the power supply circuit 17 generates and supplies control voltages for the first operation unit 16, the control circuit 18, and the first communication circuit 19, and supplies them to the first operation unit 16. The control circuit 18 and the first communication circuit 19 are made operable.

  At this time, the first communication circuit 19 transmits information notifying that the cooking apparatus 1 is placed on the second communication circuit 25 by radio waves, and causes the second communication circuit 25 to receive the information. The information is transmitted while the control voltage is applied to the first communication circuit 19, that is, while the cooking device 1 is placed on the heating device 21. On the other hand, the second communication circuit 25 extracts information from the received radio wave and outputs it to the control circuit 27. When the control circuit 27 determines that the cooking device 1 is placed from the information, The input of the operation signal from the operation unit 26 is invalidated.

  After turning on the power switch of the heating device 21, for example, when white rice is selected by the first operation unit 16 of the cooking device 1 and the rice cooking start switch is turned on, the control circuit 18 sets the operation mode corresponding to the rice cooking menu. Select and enter the preheating process in that mode of operation. First, control information for continuously energizing the heating coil 22 is output to the first communication circuit 19. The first communication circuit 19 transmits the input control information to the second communication circuit 25 of the heating device 21 by radio waves. When the radio wave is received, the second communication circuit 25 extracts control information and outputs it to the control circuit 27. The control circuit 27 drives the inverter unit of the power supply circuit 24 based on the input control information. Thereby, a voltage of 200 V is applied to the heating coil 22 and a high frequency current flows. That is, the electric power set by the control circuit 18 on the cooking apparatus 1 side is continuously output from the heating coil 22.

  On the other hand, the control circuit 18 of the cooking apparatus 1 determines whether or not the temperature detected by the container temperature sensor 6 has reached the preheating temperature, and when the temperature detected by the container temperature sensor 6 has reached the preheating temperature, the heating coil Control information for intermittently energizing 22 is transmitted to the second communication circuit 25 of the heating device 21 via the first communication circuit 19. The second communication circuit 25 extracts the control information and outputs it to the control circuit 27. The control circuit 27 drives the inverter unit of the power supply circuit 24 based on the control information, and causes the heating coil 22 to be energized intermittently. At this time, the control circuit 18 of the cooking apparatus 1 determines whether or not the elapsed time from the start of the preheating process has reached a predetermined time, and shifts to the rice cooking process when the elapsed time reaches the predetermined time.

  When the control circuit 18 enters the rice cooking process, the control circuit 18 increases the current so that the power is higher than that during the preheating process, and the first control information for intermittently energizing the heated container 3 of the cooking apparatus 1 so that the temperature does not rise abnormally. The data is transmitted to the second communication circuit 25 via the communication circuit 19. The second communication circuit 25 extracts the control information and outputs it to the control circuit 27. The control circuit 27 drives the inverter unit of the power supply circuit 24 based on the control information, and causes the heating coil 22 to be energized intermittently. At this time, the control circuit 18 of the cooking apparatus 1 operates the power supply circuit 17 to apply a voltage of 100 V to the trunk heater 13 and the lid heater 12 to flow current. By heating the side surface of the heated container 3 with the body heater 13, the rice in the heated container 3 can be cooked uniformly and plumply. Further, by heating the inner lid 8 with the lid heater 12, dew condensation adhering to the inner lid 8 can be eliminated, and the temperature in the heated container 3 can be kept high.

  Thereafter, the control circuit 18 of the cooking apparatus 1 determines whether or not the cooked rice (rice and water) in the heated container 32 has reached the boiling temperature from the temperature detected by the lid temperature sensor 7. When the control circuit 18 detects that the temperature detected by the lid temperature sensor 7 has reached the boiling temperature, the control circuit 18 proceeds to a high temperature boiling heating process in the rice cooking process. And the control circuit 18 makes the 2nd communication circuit 25 the control information which energizes continuously so that the cooked rice in the to-be-heated container 3 may become more than the predetermined temperature which can maintain a high-temperature boiling. Send and start measuring time. The second communication circuit 25 extracts the control information from the received radio wave and outputs it to the control circuit 27. The control circuit 27 drives the inverter part of the power supply circuit 24 based on the control information, and continuously energizes the heating coil 22. On the other hand, the control circuit 18 of the cooking apparatus 1 determines whether or not the above-described measurement time has passed the high-temperature boiling time. When the measurement time has not passed the high-temperature boiling time, the above-described continuous energization is continued. Let

  Further, when the control circuit 18 detects that the high-temperature boiling time has elapsed, the control circuit 18 supplies the first communication circuit 19 with control information for intermittent energization that lowers the cooked rice in the heated container 3 to a temperature at which boiling can be maintained. To the second communication circuit 25. The second communication circuit 25 extracts the control information and outputs it to the control circuit 27. The control circuit 27 drives the inverter unit of the power supply circuit 24 based on the control information and intermittently energizes the heating coil 22. Make it happen. Moreover, the control circuit 18 of the cooking apparatus 1 determines from the detection temperature of the container temperature sensor 6 whether or not the dry-up temperature at which the cooked water disappears due to the water absorption gelatinization and evaporation of the cooked rice during boiling maintenance control is reached. .

  When the control circuit 18 determines that the dry temperature has not been reached from the temperature detected by the container temperature sensor 6, the control circuit 18 performs the above-described boiling maintenance control. When the dry temperature is detected, the control circuit 18 enters the steaming process. In this case, the control circuit 18 transmits intermittent energization control information with a reduced current to the second communication circuit 25 via the first communication circuit 19. The second communication circuit 25 extracts the control information and outputs it to the control circuit 27, drives the inverter part of the power circuit 24 based on the control circuit 27 and the control information, and intermittently energizes the heating coil 22. To do. On the other hand, the control circuit 18 of the cooking apparatus 1 determines whether or not the time of the steaming process has elapsed, and information for stopping energization of the heating coil 22 when the time of the steaming process has elapsed is the first communication. It transmits to the 2nd communication circuit 25 via the circuit 19, and the induction heating of the to-be-heated container 3 is complete | finished. Further, the control circuit 18 stops the operation of the power supply circuit 17 and stops energization to the trunk heater 13 and the lid heater 12.

  When cooking rice, it is difficult to adjust the heat. If the fire is strong, the bottom of the heated container 3 will be burnt, and if the fire is weak, the rice will be boiled. Also, if the fire goes out in the middle, it will not return to delicious rice even if it is heated again, so it must be heated with optimal control from the beginning to the end of cooking. According to the first embodiment, even if the second operation unit 26 is mistakenly operated during rice cooking, it is invalidated, so that it is possible to cook rice normally until the end.

  Since the cooking device 1 is provided with the first operation unit 16 so that the operation mode can be selected, it is not necessary to provide the cooking mode and operation keys for cooking rice on the second operation unit 26 of the heating device 21. The menu selection of the second operation unit 26 can also be easily operated without deepening the hierarchy. In addition, by providing the cooking device 1 with the first operation unit 16, the user simply places the cooking device 1 on the heating device 21 and then simply cooks the rice by simply pressing the “cooking” start button. Can do.

  Since the cooking device 1 is not provided with the heating coil 22 and a circuit for energizing the heating coil 22, the cooking device 1 can be reduced in weight, and thus is easy to carry. Moreover, since the cooking apparatus 1 is made to heat with the heating apparatus 21 which uses 200V as a power supply, it can cook rice with strong thermal power.

  Further, the power of the body heater 13 and the lid heater 12 provided in the cooking device 1 is set to a voltage generated in the power receiving coil 14 magnetically coupled to the power feeding coil 23 mounted on the heating device 21, and the heating device 21. The heated container 3 in the cooking apparatus 1 is induction-heated by the heating coil 22 provided in the cooking device 1. For this reason, it becomes possible to start cooking simply by putting the cooking apparatus 1 on the heating apparatus 21, and the structure of the cooking apparatus 1 is simplified compared with the conventional rice cooker. In addition, since the cooking apparatus 1 does not require a power cord, even if it is used around water, the power cord is not squeezed and water does not enter, so that it does not cause a short circuit due to water and ignites. Risk can be prevented.

  In addition, when transmitting control information from the first communication circuit 19 to the second communication circuit 25, radio waves are used, so that circuit failure due to spillage of water and ingredients can be prevented.

  In the first embodiment, it is described that the heating device 21 is provided with the heating coil 22 and the power feeding coil 23, but the present invention is not limited to this. For example, the bottom size of the container 3 to be heated is made smaller than the outer diameter of the heating coil 22, and the heating coil 22 is composed of two or more coils having different diameters. The coil 14 may be magnetically coupled. In this case, by controlling only the coil having a large diameter separately, the timing of power feeding to the cooking apparatus 1 can be controlled, and control for separately heating the lid heater 12, the body heater 13, and the bottom of the heated container 3 can be realized. .

  Moreover, although the container temperature sensor 6 was provided in the cooking apparatus 1, the container temperature sensor 6 may be provided in the heating apparatus 21 so that the temperature of the heated container 3 can be detected. In this case, the temperature detected by the container temperature sensor 6 is output from the second communication circuit 25 to the control circuit 18 via the first communication circuit 19. Thereby, since the container temperature sensor 6 is not mounted in the cooking apparatus 1, the cost of the cooking apparatus 1 can be suppressed. Moreover, it becomes possible to store the cooking apparatus 1 compactly.

  Furthermore, the control circuit 18 provided in the cooking apparatus 1 has the material and characteristics of the heated container 3 used in the cooking apparatus 1 as data, and the heated object stored in the cooking apparatus 1 when heating is started. You may make it determine whether the container 3 is an appropriate thing.

  When the control information is transmitted from the first communication circuit 19 to the second communication circuit 25, the control information is transmitted using radio waves. However, the first communication circuit 19 and the second communication circuit 25 are provided with connectors, You may comprise so that both connectors may be connected when the cooking apparatus 1 is mounted in the heating apparatus 21. FIG.

  The first communication circuit 19 always transmits information indicating that the cooking device 1 is placed on the second communication circuit 25 while the control voltage is applied, that is, while the first communication circuit 19 is placed on the heating device 21. However, the information may be transmitted at regular time intervals (for example, every 3 minutes).

  Furthermore, although it has been described that the heating device 21 is configured for desktop use, a built-in type may be used.

FIG. 2 is an external perspective view showing a heating device and a cooking device of a heating cooker according to Embodiment 2 of the present invention. In addition, the same code | symbol is attached | subjected to the part similar to Embodiment 1 demonstrated in FIG.
In FIG. 2, cooking device 1 placed on heating device 21 is a rice cooker that does not include a heating source as described above, and has the same configuration as that of the first embodiment shown in FIG. In the heating device 21, a left heating port 31a and a right heating port 31b indicating the mounting positions of the pan, the frying pan, the cooking device 1 and the like described above are displayed on the mounting table. Under the heating ports 31a and 31b, annular heating coils 22a and 22b, which are heating sources, are arranged, respectively. In place of the heating coils 22a and 22b, a radiant heater may be used as a heating source.

  The operation unit 32 provided on the mounting table includes a left operation unit 32a provided corresponding to the heating coil 22a of the left heating port 31a and a right operation unit provided corresponding to the heating coil 22b of the right heating port 31b. 32b. Each of the operation units 32a and 32b is provided with a liquid crystal display, and a cooking menu such as “stir-fried food” and “fried food” and various switches for setting thermal power are arranged.

  The heating device 21 includes an annular power supply coil 23 a disposed outside the outer periphery of the heating coil 22 a, a power supply circuit 24 a connected to the heating coil 22 a and the power supply coil 23 a, and the first cooking device 1. A second communication circuit 25 a is provided so as to face the communication circuit 19. The heating device 21 includes an annular power supply coil 23b disposed outside the outer periphery of the heating coil 22b, a power supply circuit 24b connected to the heating coil 22b and the power supply coil 23b, and a first of the cooking device 1. A second communication circuit 25 b is provided so as to face the communication circuit 19. Further, a control circuit 27 is provided in which the operation unit 32 and the second communication circuits 25a and 25b are connected to the input side, and the power supply circuits 24a and 24b are connected to the output side.

  The control circuit 27 has a cooking menu such as “stir-fried food” and “fried food” described above, and an operation mode for controlling energization of the heating coils 22a and 22b in accordance with the set heating power. Moreover, when the information extracted by the 2nd communication circuits 25a and 25b is information (predetermined information) which notifies the mounting of the cooking apparatus 1, the control circuit 27 is the heating coil 22a facing the cooking apparatus 1, The operation signal from each operation part 32a, 32b with respect to the specified heating coil 22a, 22b is invalidated, and specific heating coil 22a, 22b is controlled according to only the control information from the cooking device 1.

Next, the operation of the heating device and the cooking device of the cooking device configured as described above will be described.
For example, when the cooking device 1 is placed in the right heating port 31b of the heating device 21 and then the power switch of the heating device 21 is turned on, the power supply circuits 24a and 24b of the heating device 21 operate the power supply unit to 200V respectively. A voltage is applied to the feeding coils 23a and 23b of the heating ports 31a and 31b to pass a current. At this time, a voltage of 100 V is generated in the power receiving coil 14 of the cooking apparatus 1 magnetically coupled to the power feeding coil 23 b by the electromagnetic induction action and applied to the power supply circuit 17. When a voltage of 100 V is applied, the power supply circuit 17 generates and supplies control voltages for the first operation unit 16, the control circuit 18, and the first communication circuit 19, and supplies them to the first operation unit 16. The control circuit 18 and the first communication circuit 19 are made operable.

  At this time, the first communication circuit 19 of the cooking apparatus 1 transmits information indicating that the cooking apparatus 1 is placed on the second communication circuit 25b on the right heating port 31b side by radio wave. The second communication circuit 25 b that has received the radio wave extracts the information from the received radio wave and outputs it to the control circuit 27. The control circuit 27 determines from the input information that the cooking device 1 is placed on the right heating port 31b, and from the right operation unit 32b while the cooking device 1 is placed on the right heating port 31b. Disable the operation signal input. However, when the left operation part 32a by the side of the left heating port 31a in which the cooking apparatus 1 is not mounted is operated, the heating control based on the operation is performed.

  On the other hand, when the control circuit 18 of the cooking device 1 detects the rice cooking start after detecting the rice cooking menu based on the operation of the first operation unit 16, the operation mode corresponding to the rice cooking menu is selected and the operation mode is set. Each control information in a preheating process, a rice cooking process, and a steaming process is transmitted to the 2nd communication circuit 25b of the heating apparatus 21 via the 1st communication circuit 19 in order. The heating operation based on the control information in the heating device 21 is the same as in the first embodiment.

  As described above, according to the second embodiment, when the cooking device 1 is placed in one of the two heating ports 31a and 31b provided in the heating device 21, the cooking device 1 is placed. Since the heating operation based on the operation of the operation unit on the heating port side is made invalid, the rice cooking operation of the cooking device 1 due to an erroneous operation is not interrupted, and the operability is excellent. Moreover, since the operation part by the side of the heating port in which the cooking apparatus 1 is not mounted is made effective, while using the cooking apparatus 1, other cooking can be performed simultaneously with the other heating port.

  In the embodiment, when the power switch of the heating device 21 is turned on, a voltage of 200 V is applied to the power supply coils 23a and 23b. However, even if a predetermined time elapses after the power switch is turned on, 2V is applied.
