As a result, the safety valves 35a to 35d are held in the open state. Incidentally, the excitation of the electromagnetic coil is performed together with the ignition operation of the spark plug 26. Further, when the adjustment operation unit 11 provided for the burner that commanded the ignition command among the thermal power control units 17a to 17d is pushed down to the ignition operation position, the ignition extinguishing command units 12a to 12d are pressed accordingly. Then, the operation is mechanically linked to the operation position for ignition, whereby the needle valve N for the ignition command target burner is operated to an appropriate opening degree.

  After starting the ignition operation as described above, monitoring of the ignition state of the burner (step # 4, step # 8) is started based on the detection value of the thermocouple 27. That is, if ignition is not detected within 5 seconds after starting the ignition operation of the ignition plug 26, a non-ignition alarm notifying the user of ignition failure is output from a speaker attached to the stove (not shown), and then the ignition plug 26 is stopped and the corresponding safety valves 35a to 35d are closed (step # 8 to step # 10). When ignition is detected within 5 seconds after starting the ignition operation of the spark plug 26, the operation of the spark plug 26 is stopped and the process proceeds to combustion processing (step # 4 to step # 6). In the combustion process (step # 6), when the standard burner 1a is in the combustion state, if the frying operation by the frying key 21 is set, the opening / closing electromagnetic valve 33 is opened based on the detection result of the temperature sensor 28. The temperature is adjusted by adjusting the degree.

  In this combustion process, when an ignition command is issued by operating the ignition / extinguishing command unit 12a to 12d corresponding to a burner different from the burning burner, a newly operated ignition / extinguishing command unit For the burners corresponding to 12a to 12d, the process shown in the flow of Step # 1 to Step # 6 (when branched at Step # 4, Step # 8 to Step # 10) is executed in the stove control unit H1.

  When any one of the ignition / extinguishing command units 12a to 12d held in the operation position in the combustion state is switched to the non-operation position that is the fire extinguishing position, the corresponding appliance plug switches SW1 to SW4 are turned off. The control unit H1 closes the safety valves 35a to 35d corresponding to the ignition / extinguishment command units 12a to 12d that have been restored by stopping the excitation of the electromagnetic coil, and ends the combustion state of the corresponding burner (step #). 7, Step # 10). Incidentally, in the figure, it is described that the process of stopping the ignition operation of the spark plug 26 is executed in step # 10. However, when step # 5 is executed, the ignition operation of the ignition plug 26 has already been performed. Since it is stopped, the ignition operation stop process is unnecessary.

  After closing the corresponding safety valves 35a to 35d due to the failure of ignition or the end of the combustion state, the stove control unit H1 performs all the appliance plug switches SW1 to SW4 corresponding to the four burners 1a, 1b, 1c, and 2. If all the appliance plug switches SW1 to SW4 are off (step # 11), the interlocking signal S1 is turned off (step # 12).

  Since the stove control unit H1 is configured to operate in this manner, the ignition / extinguishment command units 12a to 12d for any one of the burners of the gas stove are operated, and any one of the burners is temporarily in a combustion state. Then, the interlock signal S1 is not turned off until the ignition / extinguishment command units 12a to 12d for all the burners of the gas stove are switched to the non-operation position.

  Next, the operation of the remote control unit H2 will be described based on the flowcharts shown in FIGS. The remote control control unit H2 changes the interlock signal S1 output from the stove control unit H1 from off to on or from on to off, the exhaust state switching command S2 commanded by the operation button 37, and the air volume switching button 38. Detecting that either the air volume switching command S3 commanded or the illumination lighting state switching command S4 commanded by the illumination button 39 is input (step # 1 to step # 6). Depending on the result, the type of operation command to be commanded to the range hood F is set (step # 7 to step # 11).

The types of operation commands that can be set in step # 7 to step # 11 are shown in FIG. The setting of the type of operation command is specifically performed as follows.
When the change of the interlocking signal S1 from OFF to ON is detected, the command type is set to the heating appliance interlocking ON command M1 (step # 7).
When a change from on to off of the interlock signal S1 is detected, the command type is set to the heating appliance interlock OFF command M2 (step # 8).
When the exhaust state switching command S2 is detected, the command type is set to the exhaust state switching command M3 (step # 9).
When the air volume switching command S3 is detected, the command type is set to the air volume switching command M4 (step # 10).
When the lighting lighting state switching command S4 is detected, the command type is set to the lighting lighting state switching command M5 (step # 11).

  When the setting of the command type is completed by the processing from step # 1 to step # 11, the remote control device H2 executes transmission processing (step # 12). In the transmission process, an operation command in which a command type is set is encoded based on a plurality of specifications, a header is attached to encoded information (hereinafter referred to as a command code D), and the infrared signal SD is then added. This is a process of outputting from the transmission units 7, 8 and 9.

The transmitted infrared signal SD is a signal conforming to the infrared communication standard. Specifically, a pulse signal having a duty ratio of 1/3 and a frequency of 37.917 [kHz] is used as a carrier, and as shown in FIG. 9, a combination of a carrier time T _CD-ON and a carrier timeless T _CD-OFF It consists of The infrared signal SD is composed of a header part SD-H and a data part SD-D, and the length (word length) of the transmission signal SD is 67.5 [ms] or less including the header length of 13.5 [ms]. The header part is represented by a carrier time T _CD-ON of 9.0 [ms] followed by a carrier no-time T _CD-OFF of 4.5 [ms], and the data part SD-D has two types of encoding forms different from each other. It consists of symbols “0” and “1”. The code “0” is encoded by a signal of 1.126 [ms] composed of a carrier time T _{CD-ON of} 0.563 [ms] and a carrier non-time T _CD-OFF that continues thereafter for the code “1”. Is encoded with a signal of 2.25 [ms] composed of a carrier time T _CD-ON of 0.563 [ms] followed by a carrierless time T _{CD-OFF of} 1.688 [ms].

  On the other hand, the command code D constituting the code sequence of the data section SD-D adopts a code specification that differs depending on the manufacturer of the range hood F or the type of the range hood F. The correspondence relationship of D does not necessarily match. Therefore, when the control device H2 commands a certain operation command to the range hood F in the transmission process, a plurality of types of commands expected as command codes corresponding to the code system adopted by the range hood F receiving device are used. A code is read from a command code table prepared in advance, and a plurality of types of command codes are sequentially loaded on the infrared signal SD at predetermined intervals and transmitted. Hereinafter, based on the flowchart shown in FIG. 10, the transmission process which the control apparatus H2 performs is demonstrated in detail.

In step # 1 of the transmission process, the command code D to be transmitted is selected based on the set type of operation command and the value of the specification flag Fc with reference to the command code table TB. FIG. 11 shows a command code table TB in which command codes D _{11 to} D ₅₃ representing each operation command are arranged for each type of operation command M1 to M5. This table may be created based on information on the specification of the range hood F command code published by each range hood manufacturer. In the present embodiment, as an example, a code table corresponding to three types of command code specifications is created. The value of the specification flag Fc is incremented after a command code with a certain specification is transmitted on the infrared signal SD. Therefore, the command code D to be transmitted next is selected from the command code table TB based on the value of the specification flag Fc different from the previously transmitted command code. The initial value of the specification flag Fc is “0”.

In the following description, as a specific example, a transmission process of a heating appliance interlocked ON command of the range hood F that is commanded when the burner is ignited will be described. When the burner is ignited, since the start control signal S1 output from the stove control unit H1 is input to the remote control unit H2, a heating appliance interlock ON command M1 is set as the command type of the operation command for the range hood F. Is set. Accordingly, D ₁₁ is selected as the first transmission code selected with reference to the transmission code table because the specification flag Fc is the initial value “0”.

When the transmission code is selected to D _11, at step # 2, for measuring the timing of starting the next transmission (transmission of command code D _12), and sets the transmission interval timer T1. It is necessary to measure the timing for starting the next transmission. Once the receiving device of the range hood F receives the infrared signal SD, while the identification processing of the infrared signal SD and the operation command processing based on the infrared signal SD are performed, This is because a new infrared signal SD cannot be received. For example, if the transmission interval becomes too short, the next infrared signal SD will be transmitted when the receiving device of the range hood F is in the reception refusal state, and the command code (for example, the infrared signal SD) if after the infrared signal SD loaded with instruction code D ₁₁ is sent, so that the instruction code D ₁₂₎ is not received by the receiver of the range hood F. In order to avoid this inconvenience, it is necessary to transmit the next infrared signal SD after the receiving device of the range hood F enters the reception-permitted state. In this embodiment, the set time of the transmission interval timer T1 is set to 108 [ms] from the start of transmission of the previous infrared signal SD.

At step # 3, the command code D ₁₁ which is selected is cited in the code of the data part SD-D, in further subjected header portion SD-H, infrared signals SD is transmitted. Specifically, the remote control is performed based on the time configuration information on the presence / absence of the carrier indicating the header section SD-H and the time configuration information on the presence / absence of the carrier indicating the code string of the data portion SD-D determined by the command code D11. The infrared signal SD as illustrated in FIG. 9 is transmitted by the unit H2 controlling the transmission time of the carrier transmitted by the blinking operation of the infrared LEDs provided in the transmission units 7, 8 and 9.

When the transmission of the infrared signal SD is completed, in step # 4, the transmission standby state is entered until the transmission interval timer T1 counts up. When the transmission interval timer T1 is counted up, in order to transmit the command code D ₁₂ based on different specifications between command code D ₁₁ previously transmitted, increment the specification flag Fc (step # 5), again in step # 1 transmission code determining process is executed, the command code D ₁₂ as a command code D to transmit next is selected. The command code D ₁₂ is transmitted by an infrared signal SD process in step # 2 to # 6 is executed.

In this way, the process of sequentially changing the command code D and transmitting the infrared signal SD is repeated for the number of specifications prepared. In the present embodiment, when the third command code D ₁₃ is transmitted, the value of the specification flag Fc becomes “3”, and thus a series of transmission processing by the infrared signal SD of the operation command for the range hood F is completed. (Step # 6). At the end of the transmission process, the value of the specification flag Fc is set to the initial value “0” in preparation for the subsequent transmission of the operation command (step # 7).

  FIG. 12 shows the operation of the ignition / extinguishment command unit 12a provided in the heating device operation operation unit S to perform the ignition operation of the burner 1a to make the burner 1a in the combustion state, and then operate the ignition / extinguishment command unit 12a. When the burner 1a is extinguished and the burner 1a is in a combustion stopped state, the operation state of the ignition / extinguishing command unit 12a and the interlocking signal S1 output from the stove control unit H1 to the remote control unit H2 The timing chart shows changes in the infrared signal SD transmitted from the transmitters 7, 8, and 9 and the exhaust state of the range hood F based on the signal S1.

According to this timing chart, the range hood F, since the command code D ₁₂ is an infrared signal from the heating appliance conjunction ON command M1 that is loaded is effectively received, corresponding to "1" as the value of the specification flag Fc It is thought that the code system is adopted. Note that this can be confirmed from the fact that command code D ₂₂ is heated instrument interlock OFF command M2 than infrared signal placed is effectively received. Therefore, the range hood F also provides command codes D ₃₂ , D ₄₂ , D ₄₂ , D ₄₂ , D ₄₂ , D ₄₂ , D ₄₂ , D ₄₂ , D ₄₂ , D ₄₂ , D ₄₂ , D ₄₂ , D ₄₂ , D ₄₂ When an infrared signal carrying D ₅₂ (see FIG. 11) is transmitted, each command is effectively received.

Furthermore, if the range hood adopts a code system corresponding to “2” as the value of the specification flag Fc, various operation states are enabled by the command codes D ₁₃ , D ₂₃ , D ₃₃ , D ₄₃ , D _53. If this gas stove transmits an operation command with a plurality of types of command codes when a certain operation command is issued, various types of range hoods employing the above code system can be used. The operation command can be effectively commanded.

  In this way, when an operation command for the range hood as the exhaust means is commanded by the infrared signal SD, by sequentially commanding by a plurality of command codes, the operation by any command code among the plurality of command codes. The command becomes an operation command that matches the reception specification of the range hood. Therefore, as a gas stove, a plurality of types of range hoods having different communication forms can be installed as corresponding range hoods.
