Japanese Patent Laid-Open No. 10-057260

  However, in the conventional configuration, in the configuration shown in FIG. 10, when the communication light projecting unit 105a emits an optical signal with the remote control switch 105 protruding forward as shown in FIG. The signal reaches the communication light receiving unit 106 of the ventilation fan 104 without being blocked by the cabinet 101, but the communication light projecting unit 105a emits an optical signal in a state where the remote control switch 105 is housed in the main body of the heating cooker 102. In this case, there is a problem that the optical signal is blocked by the main body of the heating cooker 102 and the cabinet 101 and does not reach the communication light receiving unit 106 of the ventilation fan 104.

  The present invention solves the above-mentioned conventional problems. An open / close type operation panel arranged on the front side of the ventilator is arranged above the heating cooker when the open / close operation panel is open and closed. Using the difference in the reliability of infrared communication, when the open / close operation panel is opened, an infrared signal is transmitted only once for each operation, and the open / close operation panel is closed. If it is uncertain whether the operation panel is open or not, it is possible to eliminate unnecessary infrared transmission by transmitting the same infrared signal multiple times for each operation, and the infrared LED which is the transmission means Long life can be promoted. As described above, an object of the present invention is to provide a heating cooker in which infrared communication with a ventilator is highly reliable and the infrared communication circuit has a long life.

The present invention includes a top plate made of heat-resistant tempered glass, heating means disposed under the top plate and for heating an object to be heated, and a top operation display disposed on the upper surface of the device. And an opening / closing operation panel disposed on the front surface of the device, a heating control operation key disposed on the opening / closing operation panel or the top surface operation display unit, and the opening / closing operation panel. When the ventilator on / off, air volume adjustment key, and the heating control operation key are operated, the control means for controlling the heating means, and when the openable operation panel is open, an infrared signal is transmitted above the device. A first transmission means arranged to transmit, and a second transmission means arranged to transmit an infrared signal in front of the device when the openable operation panel is closed, the control means comprising: The control means is disposed above the top surface operation display unit, and has a function of controlling a ventilator having a first transmitting means, a second transmitting means, and a receiving means for receiving an infrared signal transmitted from the first transmitting means, When the heating means starts heating according to the operation of the heating control operation key, the same heating on signal is sent to the ventilator a plurality of times from the first sending means or the second sending means, and the heating control operation is performed. When the heating means stops heating according to the operation of the key, the same heating-off signal is sent to the ventilator a plurality of times from the first sending means or the second sending means, and the ventilation device is turned on, turned off, and the air volume. When the adjustment key is operated, by sending a signal from the first transmission means to the ventilator at least once for each operation, the openable operation panel is open. When the first transmitting means emits an infrared signal upward so that the ventilator receives the infrared signal directly, and the openable operation panel is closed, the infrared signal is mainly output by the second transmitting means. The ventilator can emit an infrared signal by reflecting forward to an obstacle such as a user or a room wall in front of the heating cooker. Irrespective of the position, it is possible to transfer an infrared signal with high reliability.

  In addition, infrared transmission when the openable control panel is open is direct infrared transmission to the ventilator compared to when the openable control panel is closed, and the operation panel is opened due to the high reliability of infrared communication. When the ventilation device is turned on / off and the air volume adjustment key is operated, it is possible to eliminate unnecessary infrared oscillation by transmitting a predetermined signal only once for each operation. The life extension of the infrared LED which is the transmitting means can be promoted.

  In addition, by turning on / off the ventilation device and shortening the number of infrared oscillations of the air volume adjustment key only once, the infrared signal output responsiveness when the key is continuously pressed can be improved, which is convenient. It is assumed that the air volume adjustment key of the ventilator is continuously pressed even in practical use, and setting the number of oscillation times to 1 leads to improved operability.

  In addition, the operation panel open / close detection means is used to identify keys and other operation switches that cannot be operated unless the operation panel is opened, such as ventilation on / off and air volume adjustment keys, and to switch the number of infrared oscillations. It is unnecessary and inexpensive.

  In the present invention, the infrared signal can be received by the receiving means of the ventilator disposed above the heating cooker both when the open / close operation panel disposed on the front is open and closed. When the operation panel is opened using the difference in reliability of infrared communication, an infrared signal is transmitted only once for each operation, and it is uncertain whether the operation panel is closed or the operation panel is open By transmitting the same infrared signal several times for each operation, unnecessary infrared transmission can be eliminated and the life of the infrared LED as a transmission means can be increased.

1st invention consists of a top plate which consists of heat-resistant tempered glass, a heating means which is arranged under the top plate and which heats an object to be heated placed on the top plate, and a top surface arranged on the upper surface of the device An operation display unit, an openable operation panel disposed on the front of the device, a heating control operation key disposed on the openable operation panel or the top surface operation display unit, and an openable operation panel The ventilation device is turned on / off, the air volume adjustment key, the control means for controlling the heating means according to the operation of the heating control operation key, and the infrared signal above the device when the openable operation panel is open. And a second transmitter arranged to transmit an infrared signal in front of the device when the openable operation panel is closed, and the control hand Has a function of controlling a ventilator that is disposed above the top surface operation display unit and has a first transmitting means, a second transmitting means, and a receiving means for receiving an infrared signal transmitted from the first transmitting means, the control means When the heating means starts heating according to the operation of the heating control operation key, the means sends the same heating-on signal to the ventilator a plurality of times from the first transmission means or the second transmission means, and the heating When the heating means stops heating according to the operation of the control operation key, the same heating off signal is sent to the ventilator a plurality of times from the first sending means or the second sending means, and the ventilator is turned on / off. When the air volume adjustment key is operated, the openable operation panel is opened by transmitting the first signal from the first transmission means to the ventilator without sending a predetermined signal only once for each operation. When the infrared signal is mainly emitted by the first transmission means and the ventilation device receives the infrared signal directly, and the openable operation panel is closed, the infrared signal is mainly transmitted by the second transmission means. A signal can be emitted forward and reflected by an obstacle such as a user or room wall in front of the heating cooker to cause the ventilator to receive an infrared signal. Irrespective of the position where the light is placed, it is possible to deliver a highly reliable infrared signal.

  In addition, infrared transmission when the openable control panel is open is direct infrared transmission to the ventilator compared to when the openable control panel is closed, and the operation panel is opened due to the high reliability of infrared communication. When the ventilation device is turned on / off and the air volume adjustment key is operated, it is possible to eliminate unnecessary infrared oscillation by transmitting a predetermined signal only once for each operation. The life extension of the infrared LED which is the transmitting means can be promoted.

  In addition, by turning on / off the ventilation device and shortening the number of infrared oscillations of the air volume adjustment key only once, the infrared signal output responsiveness when the key is continuously pressed can be improved, which is convenient. It is assumed that the air volume adjustment key of the ventilator is continuously pressed even in practical use, and setting the number of oscillation times to 1 leads to improved operability.

  In addition, the operation panel open / close detection means is used to identify keys and other operation switches that cannot be operated unless the operation panel is opened, such as ventilation on / off and air volume adjustment keys, and to switch the number of infrared oscillations. It is unnecessary and inexpensive.

According to a second aspect of the present invention, there is provided a top plate made of heat-resistant tempered glass, heating means disposed under the top plate and for heating an object to be heated placed on the top plate, and a top surface disposed on the surface of the device. An operation display unit, an openable operation panel disposed on the front of the device, a heating control operation key disposed on the openable operation panel or the top surface operation display unit, and an openable operation panel When the ventilator is turned on / off, the air volume adjustment key, and the heating control operation key according to the operation of the heating control operation key, the heating means and the open / close operation panel are open, and the infrared signal is displayed above the device. First control means arranged to send a signal, and second transmission means arranged to send an infrared signal in front of the device when the openable operation panel is closed, the control means The control means has a function of controlling a ventilator which is disposed above the top surface operation display unit and has the first transmitting means, the second transmitting means, and a receiving means for receiving an infrared signal transmitted from the first transmitting means, When the heating means starts heating according to the operation of the heating control operation key in the top surface operation display section, the same heating on signal is sent to the ventilator a plurality of times from the first sending means or the second sending means. When the heating means stops heating according to the operation of the heating control operation key of the top surface operation unit, the same heating off signal is sent to the ventilator a plurality of times from the first sending means or the second sending means. And when the heating means starts heating according to the operation of the heating control operation key in the opening / closing operation panel, or according to the operation of the heating control operation key in the opening / closing operation panel. When the means stops heating or when the ventilation device is turned on / off and the air volume adjustment key is operated, the first transmission means transmits the ventilation signal to the ventilation device at least once for each operation. Thus, when the openable operation panel is open, the infrared signal is emitted upward mainly by the first transmission means, and the ventilator directly receives the infrared signal, and the openable operation panel is When closed, the infrared signal is emitted to the ventilator by mainly emitting an infrared signal forward by the second transmission means and reflecting it to an obstacle such as a user or room wall in front of the heating cooker. The infrared signal can be delivered with high reliability regardless of the open / closed state of the operation panel and the position where the user is standing.

  In addition, infrared transmission when the openable control panel is open is direct infrared transmission to the ventilator compared to when the openable control panel is closed, and the operation panel is opened due to the high reliability of infrared communication. When the ventilation device is turned on / off, the air volume adjustment key is operated, or when the heating control operation key on the operation panel is operated, a predetermined signal transmission is performed only once for each operation. By doing so, unnecessary infrared oscillation can be omitted, and the life extension of the infrared LED which is the transmitting means can be promoted.

  Further, since the number of infrared oscillations when the operation panel is opened is shortened by only one, the infrared signal output responsiveness when the key is continuously pressed can be improved, which is convenient. It is assumed that the air volume adjustment key of the ventilator is continuously pressed even in practical use, and setting the number of oscillation times to 1 leads to improved operability.

  In addition, since the keys that cannot be operated unless the operation panel is opened and other operation switches are identified and the number of infrared oscillations is switched, the operation panel open / close detection means is unnecessary and the construction is inexpensive.

  According to a third invention, in particular, in the first or second invention, when the remaining time is set by operating an operation key in the top surface operation display unit or the openable operation panel, the heating means A timer stop means for stopping heating is provided, and when the heating of the heating means is automatically stopped after a lapse of time, the same heating off signal is sent to the ventilator a plurality of times from the first sending means or the second sending means. By transmitting, it is possible to perform infrared communication with the ventilator at the end of timer cooking with high reliability regardless of the presence of the user and the open / close state of the operation panel of the device. For example, if the operation of the ventilator is stopped or the air volume is reduced at the end of the timer cooking, unnecessary ventilation operations can be reduced, which has an energy saving effect.

  In particular, the fourth invention includes automatic cooking means for controlling the heating operation of the heating means in accordance with a predetermined sequence in the first or second invention, and the sequence of the automatic cooking means is completed and heating is automatically performed. When the heating of the means is stopped, the same heating-off signal is transmitted to the ventilator a plurality of times from the first transmitting means or the second transmitting means, so that the presence or absence of the user and the opening / closing state of the operation panel of the device are affected. Infrared communication with the ventilator at the end of automatic cooking can be performed with high reliability. For example, if the operation of the ventilator is stopped or the air volume is reduced at the end of automatic cooking, unnecessary ventilation operations can be reduced, which has an energy saving effect.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(Embodiment 1)
FIG. 1 shows the appearance of a ventilation fan that communicates with an induction heating cooker that is a heating cooker of the present invention.

  The induction heating cooker 1 is a built-in type incorporated in a kitchen cabinet 2, and a ventilation device 3 disposed above the induction heating cooker 1 includes a range hood 4, a ventilation fan 5, a receiving unit 6, and a ventilation fan operation unit. It consists of seven.

As shown in FIG. 2, the induction heating cooker 1 includes an outer shell 9 and a plate-like top plate 10 on the upper portion thereof.
And the top surface operation display unit 40. The top plate 10 is made of heat-resistant tempered glass, and a heated object 11 such as a pan is placed on the top plate 10.

  Below the top plate 10, a left IH heating coil 12, a right IH heating coil 13, and a rear IH heating coil 14 that constitute cooking means for cooking are disposed. In the front side top surface operation display section 40 of the left and right heating coils 12, 13, heating start, heating stop, thermal power setting, remaining time setting, and automatic cooking menu selection of the left and right heating coils 12, 13 are selected. A top switch 16 for performing the above and a top display unit 17 for displaying the heating state of the left and right heating coils 12 and 13 are arranged.

  An inverter circuit 18 for the heating coils 12, 13, and 14 is disposed on the right side in the outer shell 9.

  On the top plate 10, circular heated object placement portions 19, 20, and 21 corresponding to the heating coils 12, 13, and 14 are displayed.

  An openable / closable operation panel 22 is provided on the right side of the front portion of the outer shell 9. The opening / closing operation panel 22 displays the heating state of the rear heating coil 14 and the rear switch 23 for starting the heating of the rear coil 14, stopping the heating, setting the heating power, setting the remaining time, and selecting the automatic cooking menu. A rear display unit 24 is arranged.

  The open / close operation panel 22 is also provided with a ventilation fan switch 25 for starting and stopping the operation of the ventilation fan 5 and setting the air volume.

  In the closed state, the openable operation panel 22 is accommodated in the cabinet 2 as shown in FIG. In this state, when the upper part of the open / close type operation panel 22 is pushed, the open / close type operation panel 22 protrudes forward of the cabinet 2 as shown in FIG.

  The openable operation panel 22 includes a plurality of infrared LEDs that emit infrared light having a wavelength of about 940 nm. The infrared LED arranged on the same plane as the rear switch 23 is the first transmitting means 26, and the infrared LED arranged on the vertical surface when the openable operation panel 22 is closed is the second transmitting means 27. To do.

  FIG. 5 shows a block diagram of the present embodiment.

  The top surface switch 16 and the top surface operation unit 17 are controlled by the top surface control unit 15. Control of the induction heating cooker 1 as a whole is performed by the control unit 31.

  When the induction heating cooker 1 heats the heating coil 12 for the left IH, the user performs an operation to start heating the heating coil 12 with the top switch 16.

  When the top surface control unit 15 detects the operation of the top surface switch 16, the top surface control unit 15 notifies the control unit 31 that the heating coil 12 has been started to start heating, and also causes the top surface display unit 17 to heat the heating coil 12. Display presence and absence and firepower. When receiving the heating start information from the top surface control unit 15, the control unit 31 sends an instruction to start heating the left IH heating coil 12 to the inverter circuit 18, and the inverter circuit 18 performs the heating operation of the heating coil 12. . At this time, the heating power of the heating coil 12 for the left IH is a heating power set in the device in advance.

When the heating operation is started by the top switch 16, the first transmission means 26 and the second transmission means 27 are used.
The infrared signal is transmitted to the receiver 6 of the ventilator 4 with a heating-on signal, but the transmission path uses the reflection of the user as shown in FIG. 8 if the openable operation panel 22 is closed. If the openable operation panel 22 is in an open state mainly performed by the second transmission means, the first transmission is mainly performed linearly to the receiving unit 6 of the ventilator 3 as shown in FIG. Done by means. When infrared output is performed by operating the top switch, since the state of the operation panel is indeterminate, the same communication command is sent twice for each operation as shown in FIG. Send.

  When stopping the heating of the heating coil 12, when the user performs the heating stop operation of the heating coil 12 for the left IH with the top switch 16, the top surface control unit 15 transmits the operation content to the control unit 31 and the top surface control unit 15. The surface display unit 17 displays the heating stop of the heating coil 12 for the left IH, the control unit 31 instructs the inverter circuit 18 to stop the heating coil 12, and the inverter circuit 18 stops the heating of the heating coil 12. .

  When the heating operation is stopped with the top switch 16, the infrared signal is transmitted to the receiving unit 6 of the ventilator 3 by the first transmitting means 26 and the second transmitting means 27 as in the case of starting the heating operation. If the opening / closing operation panel 22 is closed, the transmission path is mainly performed by the second transmission means using the reflection of the user as shown in FIG. If it is in the open state, as shown in FIG. 9, it is performed mainly by the first transmission means 26 linearly to the receiving unit 6 of the ventilation device 4. Even when the heating operation by the top switch 16 is stopped, the state of the openable operation panel 22 is indeterminate, so that the same communication command is given for each operation on the first floor as shown in FIG. Send infrared twice.

  Next, when the ventilation fan switch 23 arranged in the operation panel 22 is operated, an infrared signal is transmitted by the first transmission means 26 and the second transmission means 27, and the infrared signal transmitted starts the operation of the ventilation fan 5. However, since the ventilation fan switch 23 is arranged on the openable operation panel 22, the transmission path is linearly connected to the receiving unit 6 of the ventilation device 3 as shown in FIG. 9. This is mainly performed by the first transmission means 26. Compared with the communication using reflection, since the accuracy of communication is high when transmitting in a straight line, infrared transmission when operating the ventilation fan switch 23 as shown in FIG. 5 is performed once for each operation. Only send operation.

  As described above, according to the present embodiment, when the openable operation panel 22 is open, the infrared signal is emitted upward mainly by the first transmission means 26 and directly to the ventilation device 3. When the openable operation panel 22 is closed, an infrared signal is mainly emitted by the second transmission means 27 to obstruct obstacles such as a user or a room wall in front of the heating cooker. It is possible to cause the ventilation device 3 to receive the infrared signal and to receive the infrared signal with high reliability regardless of the open / closed state of the openable operation panel 22 or the position where the user is standing.

  In addition, infrared transmission when the openable operation panel 22 is open is infrared transmission directly to the ventilator as compared with when the openable operation panel 22 is closed, and the reliability of infrared communication is high. When the ventilation device 3 is turned on / off and the air volume adjustment key is operated when the operation panel is opened, an unnecessary infrared oscillation is generated by transmitting a predetermined signal only once for each operation. Can be omitted, and it is possible to promote the extension of the lifetime of the infrared LED which is a transmission means.

  In addition, by turning on / off the ventilation device and shortening the number of infrared oscillations of the air volume adjustment key only once, the infrared signal output responsiveness when the key is continuously pressed can be improved, which is convenient. It is assumed that the air volume adjustment key of the ventilator is continuously pressed even in practical use, and setting the number of oscillation times to 1 leads to improved operability.

In addition, the operation panel open / close detection means is used to identify keys and other operation switches that cannot be operated unless the operation panel is opened, such as ventilation on / off, air volume adjustment keys, and other operation switches. It is unnecessary and inexpensive.

(Embodiment 2)
FIG. 6 shows a block diagram of the second embodiment and infrared output timing.

  When heating is started and stopped by the operation of the top switch 16, the state of the openable operation panel 22 is indeterminate, so the same infrared output is performed twice for each operation. When the ventilation fan switch 23 or the rear switch 24 is operated, the open / close type operation panel 22 is in a state of being surely opened, and becomes a linear infrared ray to the receiving unit 6 of the ventilator 3. Since the accuracy of communication is large, each output operation is an infrared output only once.

  As described above, according to the present embodiment, when the openable operation panel 22 is open, the infrared signal is emitted upward mainly by the first transmission means 26 and directly to the ventilation device 4. When the openable operation panel 22 is closed, an infrared signal is mainly emitted by the second transmission means 27 to obstruct obstacles such as a user or a room wall in front of the heating cooker. This makes it possible to cause the ventilator to receive an infrared signal and to deliver the infrared signal with high reliability regardless of the open / closed state of the operation panel or the position where the user is standing.

  In addition, infrared transmission when the openable operation panel 22 is open is infrared transmission directly to the ventilator 3 as compared to when the openable operation panel 22 is closed, and the infrared communication is highly reliable. When the ventilator 3 is turned on / off, the air volume adjustment key 25 is operated, or when the rear switch 23 in the open / close operation panel 22 is operated. By transmitting a predetermined signal only once for each operation, unnecessary infrared oscillation can be omitted, and the life extension of the infrared LED as a transmission means can be promoted.

  In addition, since the number of infrared oscillations when the open / close operation panel 22 is opened is shortened by only one, the infrared signal output responsiveness when the key is continuously pressed can be improved, which is convenient. It is assumed that the air volume adjustment key of the ventilator 3 is continuously pressed even in practical use, and setting the number of oscillation times to 1 leads to improved operability.

  In addition, since the number of infrared oscillations is switched by discriminating keys and other operation switches that cannot be operated unless the open / close operation panel is opened, the open / close detection means of the open / close operation panel is unnecessary, and the configuration is low.

(Embodiment 3)
FIG. 7 shows a block diagram of the third embodiment and infrared output timing. The control unit 31 has a timer stop function 32 (timer stop means) (not shown).

  When the user sets the remaining time of the heating coil 12 for the left IH with the top surface switch 16, the remaining time is transmitted from the top surface control unit 15 to the control unit 31 and the remaining time is displayed on the top surface display unit 17. The control unit 31 counts down the remaining time from the start of heating of the heating coil 12, and when the remaining time becomes 0, the inverter circuit 18 instructs the heating coil 12 to stop heating. Stop heating. At the end of the timer cooking, there is little possibility that the user is standing in front of the equipment, and the state of the openable operation panel 22 is also uncertain. Therefore, as shown in FIG. Is sent twice.

As described above, according to the present embodiment, when the heating of the heating unit is automatically stopped after a lapse of time, the same heating-off signal is ventilated from the first transmitting unit 26 or the second transmitting unit 27 a plurality of times. By transmitting to the device 3, infrared communication with the ventilation device 3 at the end of the timer cooking can be performed with high reliability regardless of the presence of the user and the open / close state of the openable operation panel 22 of the device. For example, if the operation of the ventilator 3 is stopped or the air volume is reduced at the end of the timer cooking, unnecessary ventilation operation can be reduced, and there is an energy saving effect.

  Next, the control unit 31 has an automatic cooking function 33 (automatic cooking means) (not shown). The automatic cooking function 33 is a function that controls heating start, heating stop, and heating power of the heating coil 12 according to a predetermined sequence, and when the sequence is completed, stops heating and informs the user of the end of automatic cooking. is there.

  When using the automatic cooking function 33, when the user selects a desired automatic cooking menu with the top switch 16 and starts the automatic cooking menu, the user is informed of the desired automatic cooking menu to the control unit 31. The left IH automatic cooking menu is displayed on the top surface display unit 17, and the control unit 31 instructs the inverter circuit 18 to start, stop, and heat the heating coil 12 according to a predetermined sequence.

  The inverter circuit 18 controls the heating power of the heating coil 12 according to the operation instructed by the control unit 31.

  When all the sequences are completed, the control unit 31 instructs the inverter circuit 18 to stop heating the heating coil 12 and notifies the top surface control unit 15 that the heating of the desired automatic cooking menu has been completed. The top surface display unit 17 of the unit 15 displays the end of the automatic cooking menu and notifies the user.

  At the end of the automatic cooking, there is little possibility that the user is standing in front of the equipment, and the state of the openable operation panel 22 is also uncertain, so as shown in FIG. Is sent twice.

  As described above, according to the present embodiment, when the sequence of the automatic cooking means is completed and the heating of the heating means is automatically stopped, the first transmission means 26 or the second transmission means 27 is the same multiple times. By transmitting the heating off signal to the ventilator 3, it is possible to perform infrared communication with the ventilator at the end of automatic cooking with high reliability regardless of the presence of the user and the open / close state of the open / close operation panel of the device. it can. For example, if the operation of the ventilator is stopped or the air volume is reduced at the end of automatic cooking, unnecessary ventilation operations can be reduced, which has an energy saving effect.

  The heating cooker of the present invention can be used for a heating cooker other than a heating cooker that performs infrared communication, and can also be used for communication using light or radio waves of wavelengths other than infrared as a medium, or ultrasonic communication.
