A first communication unit 6a that transmits a signal to the ventilation fan based on the control command, and a second communication unit 6b that transmits a signal to the ventilation fan based on the control command input to the second operation unit 4b.

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

  When a power switch (not shown) is pressed, the cooking device of the present invention enters a standby state. In the standby state, menus that can be operated by the first operation unit 4a and the second operation unit 4b in the figure showing the LED display state during standby of the heating cooker in the first embodiment of the present invention in FIG. 2 (for example, The LED display unit 10 corresponding to heating on / off, fried food on / off, and kettle boiling is in a blinking state. In the standby state, only menus whose LEDs are blinking can be selected.

  To start heating, heating is started when the heating on / off switch 11 of the first operation unit 4a or the second operation unit 4b is selected during the standby state.

  Next, the heating of the first heating unit 3a will be described as an example. FIG. 3 is a diagram showing an LED display state at the start of heating of the heating cooker according to the first embodiment of the present invention.

  When the heating on / off switch 11 of the first operation unit 4a is selected during the standby state of the cooking device, heating is started, and it corresponds to the heating on / off of the first operation unit 4a and the set heating power as shown in FIG. The LED display unit 10 is lit.

  When heating is started, the first communication unit 6a (here, the first heating unit) as shown in FIG. 4A (a) the operation timing chart of the communication unit at the start of heating of the heating cooker in the first embodiment of the present invention. 3a starts heating), an infrared signal (ventilation fan rotation signal) for rotating the ventilation fan is transmitted to the ventilation fan.

  Then, after a predetermined time interval t (for example, 50 μs) after the first communication unit 6a transmits the infrared signal for rotating the ventilation fan, the second communication unit 6b transmits the infrared signal (ventilation fan rotation) transmitted by the first communication unit 6a. Signal) to the ventilation fan.

  When the heating on / off switch 11 of the first operation unit 4a is selected during heating, heating is stopped and the process returns to the standby state. When the heating is stopped, as shown in FIG. 4A (b) the operation timing chart of the communication unit at the time of heating stop of the heating cooker in the first embodiment of the present invention, the first communication unit 6a replaces the ventilation fan with the ventilation fan. Send an infrared signal to stop (ventilator fan stop signal).

  Then, after transmitting the infrared signal for stopping the ventilation fan, after a predetermined time interval t (for example, 50 μs), the second communication unit 6b is the same signal as the infrared signal (ventilation fan stop signal) transmitted by the first communication unit 6a. To the ventilation fan.

  Further, during heating, the set thermal power can be increased by one step each time the thermal power up switch 14 is selected, and the set thermal power can be decreased by one step each time the thermal power down switch 15 is selected. The speed of the ventilation fan is switched according to the set heating power.

Do not send.

  In addition, since said example is a case where the 1st heating part is heated, when the 2nd heating part is heated, the 1st communication part 6a does not transmit a signal, but the 2nd communication part 6b An infrared signal is transmitted to increase or decrease the speed of the ventilation fan by one step.

  In the above description, heating has been described as an example, but the same effect can be obtained by starting and stopping an automatic cooking menu such as fried food or kettle instead of heating. Moreover, although the signal which a communication part transmits was demonstrated as an infrared signal, the same effect is acquired also in another radio signal, and it is not limited to this.

  With the above configuration, the configuration of the communication unit can be simplified, the input processing method and the communication processing method of each communication unit can be shared, and the configuration of the communication unit can be shared.

  In addition, the operation to start the ventilation fan from the communication unit at the start of heating starts the ventilation fan with communication that does not interfere with each other from the plurality of communication units, so a heating cooker with improved operational reliability to operate the ventilation fan Can be realized.

  In addition, even when a communication unit fails, the influence of the failure can be suppressed to a minimum range because a plurality of communication units are provided independently.

  Furthermore, by properly using the signal to start or stop the ventilation fan and the transmission method of the signal to change the speed of the ventilation fan, the ventilation fan can be started or stopped reliably, and even in the speed change, malfunction (such as accepting multiple speed changes) ) Can be eliminated, and improvement in reliability can be expected.
