JP-A-10-257930

  In the wireless remote control system of Patent Document 1, wiring work between the cooking device and the range hood is not required as in the wired remote control system, and can be easily installed.

  In Patent Document 1, one of the left and right side moldings that covers the gap between the left and right side surfaces of the cooking device and the floor unit (kitchen cabinet) is used as a remote control unit having the fan operation unit.

  Therefore, in the case of a cooking device that does not include a side molding, the side molding cannot be used as a fan operation unit, and a wireless signal transmission unit is installed in the front operation panel unit of the cooking device, and wireless The signal is transmitted forward, the wireless signal is reflected by the user standing in front of the cooking device, and the reflected wireless signal is received by the receiving unit provided in the range hood.

 In such a configuration, the wireless signal transmission unit may be blocked by the finger or arm of the user who operates the operation panel, and the wireless signal may not be appropriately reflected by the user's chest or abdomen. Heat cooking is performed without being activated, or the exhaust fan continues to operate even after cooking is finished.

  The present invention has been made paying attention to such a situation, and in a cooking device that controls driving and stopping of an exhaust device by a wireless remote control system, a wireless signal is reliably reflected by a user. Is the main purpose.

  In order to achieve the above object, the present invention is configured as follows.

(1) The present invention is a radio signal for controlling driving or stopping of an exhaust device that exhausts exhaust gas generated in the heating unit to the outside based on each operation for instructing heating or heating stop by the heating unit. A heating cooker that sends an infrared signal forward from a transmission unit provided in the front operation panel unit,
The time when each operation for instructing the heating or heating stop is performed, the time when 3 seconds as a set time has elapsed from the time, the time when each operation is performed, and the time when 3 seconds have elapsed A transmission control unit that transmits the infrared signal corresponding to each operation from the transmission unit over three or more times with at least one time point in the period between, wherein the at least one time point is the heating or heating It is the time when 1 second or more has elapsed from the time point when each operation for commanding the stop was performed,
The transmission unit includes an infrared LED that outputs the infrared signal, and includes a power switch operation button for operating a power switch from the front of the front operation panel unit, and the power switch operation button includes the infrared LED. The power switch operation button is arranged to be biased to the right when viewed from the front, and the infrared LED is the left end of the power switch operation button when viewed from the front. It is arranged at a position biased to the side so as to face the power switch operation button.

  According to the present invention, since the wireless signal is transmitted not only at the time when each operation for instructing heating or heating stop by the heating unit is performed, Even if the transmission unit at the time of transmitting the first wireless signal is blocked by an arm or the like, the user's finger or arm is moved after the operation, so that the wireless signal subsequently transmitted from the transmission unit is the finger or arm. The user's chest and abdomen are irradiated without being interrupted by any one of the radio signals transmitted over three times or more and can be reliably reflected by the user and guided to the exhaust device side.

  According to the present invention, since the user who performed the operation is usually in front of the cooking device for about 3 seconds, by transmitting the infrared signal during that time, the infrared signal is reliably reflected by the user to the exhaust device side. Thus, the exhaust device can be accurately controlled.

  The user who has completed the operation of the operation buttons and the like on the front operation panel unit has released his / her finger from the operation buttons and the like when 1 second or more has elapsed since the normal operation has been performed. By transmitting a radio signal when it has passed, the transmitter provided on the front operation panel unit is not blocked by the user's fingers and arms, and the radio signal from the transmitter is appropriate for the chest and abdomen of the user. Therefore, it is more reliably guided to the exhaust device side, and the exhaust device can be controlled more accurately.

  As described above, according to the present invention, in the heating cooker that controls the driving and stopping of the exhaust device by the wireless remote control method, when the operation for instructing the heating unit to heat or stop heating is performed, and thereafter Since the wireless signal is transmitted from the transmission unit of the front operation panel unit over three times, the wireless signal transmission unit is not blocked by the finger or arm of the user who operated the front operation panel unit. Sometimes, a wireless signal can be transmitted, whereby the wireless signal can be reliably reflected by the chest or abdomen of the user standing in front of the heating cooker and guided to the exhaust device side.

Thereby, the heating power of each stove burner 2 can be visually recognized by the number of lighting of the LED lamps 27.

  The drop-in stove C configured as described above is assembled to the kitchen cabinet 4 in the following procedure.

  When assembling, as shown in FIG. 5, first, all the panel covers 10, 12, 14, and 16 are temporarily fixed with a fixing tape (not shown) in a state where the panel covers 10, 12, 14, and 16 are folded and turned to the grill cabinet 3 side. All the panel covers 10, 12, 14, 16 are accommodated in the front outer region of the main body 1 in view.

  When the panel covers 10, 12, 14, and 16 are in the state of being folded and turned to the grill side as described above, when the front portion of the main body 1 is inserted from the upper surface opening 4 a of the kitchen cabinet 4, the panel covers 10, 12, 14 and 16 do not interfere with the periphery of the upper surface opening 4 a of the kitchen cabinet 4, and the main body 1 can be inserted through the upper surface opening 4 a of the kitchen cabinet 4 without difficulty. Thereafter, the flange portion 1 f provided on the four peripheral edges of the upper end of the main body 1 is locked to the peripheral edge of the upper surface opening 4 a of the kitchen cabinet 4, and the front operation panel portion P and the grill cabinet 3 are exposed to the front opening 4 b of the kitchen cabinet 4. The state shown in FIG.

  If the opening size of the front opening 4b of the kitchen cabinet 4 in the front view is the same as the front view size of the front panel P, the front operation panel portion is inserted when the front operation panel portion P is inserted into the front opening 4b of the kitchen cabinet 4. Since P and the peripheral edge of the front opening 4b are likely to interfere with each other and the construction becomes difficult, it is desirable that the opening dimension of the front opening 4b in the front view is sufficiently larger than the front view dimension of the front operation panel portion P. According to such dimension setting, in the state of FIG. 8 where the front operation panel portion P faces the front opening 4b of the kitchen cabinet 4, there is a gap between the periphery of the front operation panel portion P and the periphery of the front opening 4b. A gap will occur.

  In the state of FIG. 8, the gap below the front operation panel portion P is inconspicuous because the front operation portion P exists, and the gap above the front operation panel portion P is forward on the upper surface of the kitchen cabinet 4. The front end of the countertop 4c that protrudes is inconspicuous, but the gap d on the left and right sides of the front operation panel P is conspicuous. A clean appearance can be maintained by performing the process of closing the gap d on the left and right sides of P.

  That is, from the state shown in FIG. 8, the fixing tape (not shown) is removed and the temporary fixing restraint is released, and then the panel covers 10, 12, 14, 16 are closed around the support shafts x0, x1, x2, x3. By rotating to the position, the gaps d on both the left and right sides of the front operation part P are covered by the extensions 10a, 12a, 14a, 16a provided at the respective free ends, and the front of the kitchen cabinet 4 The state shown in FIG. 9 is maintained with a clean appearance with a sense of unity with the front surfaces of the panel covers 10, 12, 14, and 16.

  Thereafter, the top plate 5 is attached to the main body 1 and the grill tray 3a with a front lid is attached to the grill cabinet 3, whereby the assembly of the drop-in stove C into the kitchen cabinet 4 is completed, and the state shown in FIG. 2 is obtained. .

  As shown in FIG. 7, a locking claw 29 is provided on the back surface of the panel cover 10, and an engagement hole 30 for engaging with the locking claw 29 is provided in the front panel 9. When 10 is rotated to the closed position, the locking claw 29 is engaged with the engagement hole 30 and held in the closed state, so that it does not rotate unintentionally toward the open position. Even in the closed state in which the locking claw 29 is engaged with the engagement hole 30, the panel cover 10 can be rotated toward the open position by pulling forward with a slightly strong eye force. is there. The other panel covers 12, 14, 16 can also be held in the closed position by the same structure as described above, and can be opened and rotated by pulling them forward with a slightly strong eye force. .

  In the cooking device configured as described above, in conjunction with the ignition / extinguishing operation of the stove burner 2 and the ignition / extinguishing operation of the grill burner 33, that is, in conjunction with the heating / heating stop operation of the heating unit. Then, the driving / stopping of the exhaust fan 34 provided in the range hood B which is an exhaust device is controlled by an infrared signal which is a radio signal. The configuration will be described below.

  As shown in FIG. 7, an infrared LED 35 for outputting an infrared signal for controlling the exhaust fan and an LED lamp 36 as a power monitor lamp for displaying a power on / off state are provided at the upper right portion of the front panel 9 in the operation unit Sa. And the power switch 23 are arranged close to each other in the left-right direction, and the infrared LED 35, the LED lamp 36, and the power switch 23 arranged in parallel are opposed to the power switch operation button 24 mounted on the panel cover 10 from the back side. Arranged to do.

  As described above, the power switch operation button 24 is formed in a horizontally long oval shape so as to face the parallel infrared LEDs 35, the LED lamps 36, and the power switch 23. A recessed portion 24a for entering and an operation projection 24b for pressing the power switch are provided. The power switch operation button 24 is made of, for example, a black resin material that transmits infrared light, and an infrared signal output from the infrared LED 35 near the portion where the recess 24a of the power switch operation button 24 is formed. Is a translucent part 37 that transmits and transmits the light forward.

 In this embodiment, the infrared LED 35 and the translucent unit 37 constitute a transmission unit that transmits an infrared signal forward, and transmission control of the infrared signal by this transmission unit is performed by the main control unit 20 of FIG.

  In this embodiment, the infrared LED 35 is disposed so as to face a position biased to the left end side of the power switch operation button 24 when viewed from the front, and the translucent portion 37 includes the power switch operation button when viewed from the front. 24 is biased to the left end side. Therefore, when a user stands in front of the cooking table A, an infrared signal can be transmitted from a position closest to the user of the power switch operation button 24, and signal reflection by the user can be ensured. it can. In contrast to this embodiment, in the case where the power switch operation button 24 is arranged to be shifted to the left side of the stove center, the light transmitting portion 37 may be positioned to the right side of the power switch operation button 24.

  In addition, a light diffusing portion 38 made of a transparent resin such as an acrylic resin that diffuses monitor light from the LED lamp 36 forward is integrally incorporated in the left and right central portions of the power switch operation button 24 so that the power switch 23 is turned on. As a result, the light diffusing unit 38 at the center of the power switch operation button 24 shines so that the power-on state can be viewed from the front.

  In a state where the panel cover 10 is closed and the front panel 9 is covered, the front surface of the front panel 9 is visually recognized by the user, as shown in FIG. The translucent part 37 that transmits the infrared signal is visually recognized as the power switch operation button 24. Therefore, the aesthetic appearance is not impaired as in the case where the translucent part is installed independently, and the power switch operation button 24 is operated with a large operation surface due to the provision of the translucent part 37. It becomes easy and functional beauty increases.

  With respect to the above-described cooking device, a receiving portion 39 for receiving an infrared signal is disposed obliquely forward and downward as shown in FIG. An infrared signal that is sent out slightly upward from the light unit 37 and reflected by a user standing in front of the cooking table A is received by the receiving unit 39.

  Next, basic transmission control on the stove side and basic exhaust fan control on the range hood side will be described.

[Transmission control: see FIG. 11]
On the stove body side, first, whether or not the first ignition command (first ignition command) is issued to any one of the burner burner 2 or the grill burner 33 from the state where all the burners are extinguished by the user's operation. And, it is determined whether or not a fire extinguishing command (final fire extinguishing command) that puts all the burners into a fire extinguishing state is issued (step s01), and when it is recognized that the initial ignition command or the final fire extinguishing command is issued, Measurement of the elapsed time from the time when the command is issued by the user's operation is started, and an infrared signal is transmitted from the infrared LED 35 (step s02). That is, the first infrared signal is transmitted when the first ignition command or the final fire extinguishing command is issued by the user's operation. Even if an ignition command for another burner is issued after the first ignition command is issued, an infrared signal is not transmitted in response to this subsequent ignition command. Even if a fire extinguishing command is issued for any one of the burners in a state where a plurality of burners are ignited, an infrared signal is not transmitted while the burner in the ignition state remains.

  Next, when it is confirmed that a predetermined time T1 (for example, 1 second) has elapsed since the occurrence of the ignition command or the final fire extinguishing command, a second infrared signal is transmitted again from the infrared LED 35 (steps s03, s04). .

  Furthermore, when it is confirmed that the set time T2 (3 seconds) has elapsed since the occurrence of the ignition command or the final fire extinguishing command, the third infrared signal is transmitted again from the infrared LED 35 (steps s05 and s06).

  As described above, the infrared signal is transmitted three times, when the ignition command or the final fire extinguishing command is generated by the user's operation, when the predetermined time T1 has elapsed, and when the set time T2 has elapsed. Even if the translucent portion 37 of the power switch operation button 24 that is the transmission end of the infrared signal may be interrupted during the first transmission of the infrared signal with the finger or arm of the user performing the operation, By moving the user's hand or arm, the second or third infrared signal is irradiated to the chest or abdomen in front of the user without being blocked by the fingers or arms, and the infrared signal is reflected by the user to the range hood side. Opposite, it is guided to the receiver 39.

  In addition, since it seems that the user who performed ignition operation exists in front of the cooking table A for at least several seconds, it is desirable to transmit an infrared signal in the meantime. Therefore, the time T2 is preferably set to 3 seconds.

[Exhaust fan control: See Fig. 12]
On the range hood side, first, it is determined whether or not an infrared signal has been received by the receiver 39 (step s11), and when it is recognized that the time has been received, measurement of the time elapsed from that point is started (step s11). s12). When the infrared signal is received by the receiving unit 39, it is ignored even if it is received after that time T2. That is, of the infrared signals transmitted from the transmitter 37 three times, only the infrared signal reflected by the user and first received by the receiver 39 is employed.

  Next, it is determined whether or not the exhaust fan 34 shown in FIG. 1 is currently stopped (step s13). If the exhaust fan 34 is stopped, the exhaust fan 34 is immediately activated (step s14). .

  In addition, when the exhaust fan 34 is operating, the elapsed time from when the infrared signal is received starts to be measured, and the exhaust fan 34 is stopped after it is recognized that the set time T3 has elapsed. (Steps s15, s16, s17). As described above, exhaust and hot air remain for a while even after the fire extinguishing operation is performed. Therefore, exhaust and hot air can be sufficiently discharged by delaying the stop of the exhaust fan 41. The time T3 for delaying the stop of the exhaust fan 41 is preferably 3 minutes to 5 minutes.

  The fan stop control is executed when the signal is not received again until the time T3 elapses. When the signal is received until the time T3 elapses, that is, the fan is stopped. When any one of the burners 2 and 33 is ignited from the state where all the burners 2 and 33 are extinguished during the delay time T3, an infrared signal is transmitted based on the output of the ignition command, Based on the recognition that the infrared signal has been received, it is determined that one of the burner 2 or the grill burner 33 is in an ignition state, and the operation of the exhaust fan 34 is continued (steps s16, s18). ).

  If necessary, a manual operation section is provided at the front end of the hood B of the range hood B so that the exhaust fan 34 can be arbitrarily driven and stopped, an exhaust amount adjusting operation for changing the rotational speed of the exhaust fan 34, and the range. It is preferable that the lighting device provided in the hood B can be turned on / off.

(Other embodiments)
The present invention can also be implemented in the following forms.

 (1) Since the translucent part 37 is located on the right side with respect to the front of the cooking table, the attitude of the infrared LED 35 in a plan view is inclined so that an infrared signal is transmitted inward slightly. When the infrared signal is sufficiently irradiated to the user standing on the front of the cooking table, the infrared signal is more accurately reflected.

  (2) In the above embodiment, the case where the power switch operation button 24 is provided with the light transmitting portion 37 for transmitting an infrared signal is illustrated. However, a dedicated light transmitting portion 37 is provided separately from the power switch operation button 24. It can also be implemented.

  (3) The gap formed between the front opening 4b of the kitchen cabinet 4 and the front panel portion P is closed with the side molding, and the light transmission portion 37 for sending an infrared signal for controlling the exhaust fan is provided in the side molding. The present invention can also be applied to a heating cooker in the form.

  (4) In the above embodiment, the gas burner is used as the heating unit. However, the heating unit is not limited to the gas burner, and the heating cooker C using various heating units such as an electric heater or an IH heater is used. It is applicable to.

  (5) The heating cooker C is not necessarily limited to the built-in type, and the present invention can also be applied to a top-mounted heating cooker.
