A ventilator configured to control the ventilating operation of the ventilating operation unit based on the ventilation operation command information regarding the ventilating operation from the external device received by the communication processing unit, and the ventilator It is related with the ventilation system provided with.

  Such a ventilator and a ventilation system control ventilation operation such as operation start and operation stop of a ventilation operation unit based on ventilation operation command information related to ventilation operation communicated from an external device such as a stove or a water heater. Thus, the ventilation operation unit can be operated in conjunction with the operation process of the external device (for example, see Patent Document 1).

  In Patent Document 1, when a gas stove as an external device operates a stove burner or a grill burner, or when the exhaust temperature of a gas oven provided in the lower part of the gas stove becomes high, as ventilation operation command information If the stove burner or grill burner is not activated, or if the exhaust temperature of the gas oven at the bottom of the gas stove is low, the ventilation stop command information is sent.

JP 2008-128495 A

The ventilation control unit of the ventilation device is generally configured using a microcomputer, and the microcomputer may cause malfunction such as freezing due to various causes.
When such a malfunction occurs, the malfunction is often resolved by temporarily shutting off the power supply.
By the way, the ventilation control unit is generally equipped with a reset input terminal. If the above malfunction occurs, the malfunction can be resolved by inputting a reset signal to the reset input terminal. Often done.

  In conventional ventilators and ventilation systems, if the ventilation control unit of the ventilator malfunctions, even if the ventilation start command is commanded, the response signal cannot be received in the proper setting state, so it is assumed that it is abnormal. The process will not be executed.

In such a case, the user of the external device makes a maintenance call, and the service worker has the malfunction corrected.
By the way, there are cases where the user of the external device understands that the malfunction may be resolved by temporarily shutting off the power supply to the ventilation control unit. In some cases, the user of the device performs an operation of intermittently supplying power to eliminate the malfunction.

As described above, when a maintenance call is made to resolve a malfunction, not only is it troublesome to make a maintenance call, but also external equipment is used for a long time until the malfunction is resolved by a service worker. There are inconveniences that can not be inconvenienced.
In addition, when the user of the external device performs an operation to interrupt the power supply to eliminate the malfunction, there is no inconvenience that the external device cannot be used for a long time, but the operation to interrupt the power supply There is a hassle that must be done.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a ventilator that can automatically eliminate the malfunction of the ventilation control unit, and a ventilation system including the ventilator. It is in.

The first characteristic configuration of the present invention is provided with a communication processing unit that communicates with an external device that performs an operation process that requires ventilation, and a ventilation control unit that controls the operation of the ventilation operation unit that performs the ventilation operation. And
The ventilation control unit is configured to control ventilation operation of the ventilation operation unit based on ventilation operation command information related to ventilation operation from the external device received by the communication processing unit. ,
The present invention is characterized in that a reset processing unit that executes a reset process for resetting the ventilation control unit in response to a reset command from the external device is provided.

  In other words, when a reset command is issued from an external device, the reset processing unit executes a reset process for resetting the ventilation control unit, and the ventilation control unit causing malfunction such as freeze Can be resolved.

Therefore, when the ventilation start command is commanded, if the response signal cannot be received in the proper setting state, if the external device is configured to command the reset command, the malfunction of the ventilation control unit is automatically resolved. It becomes possible.
That is, if the malfunction of the ventilation control unit is solved by the reset process, the malfunction of the ventilation control unit can be automatically resolved.

  In short, according to the first characteristic configuration of the present invention, it is possible to provide a ventilation device that can automatically eliminate the malfunction of the ventilation control unit.

The second feature configuration of the present invention is in addition to the first feature configuration described above.
When the signal form of the transmission signal received from the external device received by the communication processing unit is a reset request signal form, the reset processing unit executes the reset process as a reset command from the external device. It is characterized in that it is configured.

  That is, when the signal format of the transmission signal received from the external device received by the communication processing unit is the signal format for reset request, the reset processing unit executes the reset process as a reset command from the external device.

  In this way, when the signal form of the transmission signal from the external device received by the communication processing unit becomes the reset request signal form, it is assumed that it is a reset command from the external device. It is possible to issue a reset command from an external device with a simple configuration that effectively uses the communication function of a communication processing unit provided for information communication.

  In short, according to the second characteristic configuration of the present invention, in addition to the operational effects of the first characteristic configuration described above, a ventilation device that can issue a reset command from an external device with a simple configuration can be provided. .

The third feature configuration of the present invention is in addition to the second feature configuration described above.
The reset request signal form is characterized in that the carrier wave is output in a state where the continuous carrier wave continuous existence time is made larger than the normal communication carrier wave continuous existence time.

That is, the communication of the ventilation operation command information related to the ventilation operation is performed by modulating the carrier wave according to the information to be communicated. Specifically, the code is generated in accordance with information to be communicated by intermittently transmitting the carrier wave.
The reset request signal form is determined to output a carrier wave in a state in which the continuous carrier time of the carrier wave is set to be larger than the continuous carrier wave carrier time for normal communication. When the time exceeds the continuous communication carrier time for normal communication, the reset processing unit executes the reset process as a reset command from an external device.

In this way, since the continuous presence time of the carrier wave is increased from the continuous communication carrier time for normal communication, a reset command is issued from an external device, so the configuration of the communication processing unit is utilized as much as possible. It is possible to issue a reset command from an external device with a simple configuration.
In other words, the communication processing unit is provided with a filter circuit for identifying a carrier wave, but information on the carrier wave received through the filter circuit for identifying the carrier wave also when a reset command is issued from an external device. Therefore, it is possible to determine the reset command from the external device with a simple configuration that effectively uses the configuration of the communication processing unit as much as possible.

  In short, according to the third feature configuration of the present invention, in addition to the operational effects of the second feature configuration described above, a reset command is issued from an external device with a simple configuration that effectively uses the configuration of the communication processing unit as much as possible. It is possible to provide a ventilator capable of

The fourth feature configuration of the present invention is in addition to the second feature configuration described above.
The reset request signal form is characterized in that the carrier wave is output in a state where the frequency of the carrier wave is changed to a frequency different from the frequency for normal communication.

That is, the communication of the ventilation operation command information related to the ventilation operation is performed by modulating the carrier wave according to the information to be communicated. Specifically, it is performed in a form in which a code corresponding to information to be communicated is generated by modulating a carrier wave.
Since the reset request signal form is determined to output the carrier wave with the carrier wave frequency changed to a frequency different from the normal communication frequency, the reset request signal form is different from the normal communication frequency. When a frequency carrier wave is received, the reset processing unit executes a reset process on the assumption that it is a reset command from an external device.

  Thus, since the reset command is commanded using a carrier wave having a frequency different from the frequency for normal communication, communicating the ventilation operation command information related to the ventilation operation and communicating the reset command. Therefore, when defining a communication format for commanding a reset command with a carrier with a frequency different from the frequency for normal communication, it is possible to freely decide the time for outputting the carrier, etc. The arrangement does not need to be determined precisely as in the case of communicating ventilation operation command information related to the ventilation operation, and the reset processing unit can be easily designed and manufactured.

  In short, according to the fourth characteristic configuration of the present invention, it is possible to provide a ventilation device that facilitates the design and manufacture of the reset processing unit in addition to the operational effects of the second characteristic configuration described above.

In addition to the first feature configuration described above, the fifth feature configuration of the present invention includes:
The communication processing unit is configured in a wireless communication type,
The reset processing unit is configured to receive the reset command communicated by wire.

  That is, the communication processing unit receives the ventilation operation command information related to the ventilation operation by wireless communication using infrared rays or the like, and the reset processing unit receives the reset command communicated by wire. Thus, the reset process is executed.

  In this way, since the reset command is communicated to the reset processing unit using a wired connection, it is possible to appropriately communicate the reset command to the reset processing unit in a state where the reset command is not easily affected by disturbances, etc. It becomes easy to perform the reset process by the reset processing unit accurately.

  In short, according to the fifth characteristic configuration of the present invention, in addition to the operational effect of the first characteristic configuration described above, the reset command is accurately communicated to the reset processing unit, and the reset processing by the reset processing unit is accurately performed. Can provide a ventilation device.

In addition to any of the first to fifth feature configurations described above, the sixth feature configuration of the present invention includes:
The reset processing unit is configured to block power supply to the ventilation control unit for a predetermined time.

That is, when the reset processing unit is instructed to reset, the power supply to the ventilation control unit is cut off for a predetermined time as the reset processing.
Since the ventilation control unit starts up by executing the initialization process by supplying power again after the power supply is cut off, even when an operation failure such as freezing has occurred, The malfunction is eliminated.

  Thus, since the ventilation control unit is reset by shutting off the power supply to the ventilation control unit for a predetermined time, the ventilation control unit is provided with a special configuration for resetting. It becomes possible to eliminate the malfunction of the control unit.

  In short, according to the sixth feature configuration of the present invention, in addition to any of the functions and effects of the first to fifth feature configurations described above, even when the ventilation control unit is not provided with a special configuration for resetting, It is possible to provide a ventilation device that can eliminate the malfunction of the ventilation control unit.

In addition to any of the first to fifth feature configurations described above, the seventh feature configuration of the present invention includes:
The reset processing unit is configured to output a reset signal to a reset input terminal of the ventilation control unit.

That is, when the reset processing unit is instructed to reset, a reset signal is output to the reset input terminal of the ventilation control unit as a reset process.
When the reset signal is input to the reset input terminal, the ventilation control unit interrupts the processing so far, executes the initialization processing, and starts up, causing a malfunction such as freezing. Sometimes the malfunction is resolved.

  Thus, since the reset signal is output to the reset input terminal of the ventilation control unit and the ventilation control unit is reset, the reset processing unit simply outputs the reset signal when the reset command is instructed. Only a simple configuration can be achieved.

  In short, according to the seventh characteristic configuration of the present invention, in addition to the operational effects of the first to fifth characteristic configurations described above, it is possible to provide a ventilator that can simplify the configuration of the reset processing unit.

When the external device cannot receive the response information for the communication of the ventilation operation command information in an appropriate setting state, the external device is configured to command the reset command as an abnormality of the ventilation device. Features.

That is, response information to the ventilation operation command information from the external device is communicated to the external device from the communication processing unit of the ventilation device. And when an external apparatus cannot receive the response information in a setting appropriate state, it will instruct | indicate a reset command as abnormality of a ventilation apparatus.
By the way, when the reset processing unit of the ventilator is instructed to reset, it executes the reset process to reset the ventilation control unit, and as a result, the ventilation control unit malfunctioning causing freeze etc. It is as above-mentioned that it can eliminate.

  In this way, between the ventilator and the external device, the abnormality of the ventilator is determined based on the state of communication inherently performed, and a reset command is issued. It is possible to instruct a reset command by detecting a simple configuration that effectively uses the configuration and functions originally provided.

  In short, according to the eighth characteristic configuration of the present invention, it is possible to provide a ventilation system that can detect the occurrence of an abnormality in the ventilation device with a simple configuration and issue a reset command.

The ninth feature configuration of the present invention is in addition to the eighth feature configuration,

The external device determines whether or not the ventilation device is normal based on the actual ventilation output communicated from the communication processing unit. It is characterized by being configured to do so.

That is, the actual ventilation output detected by the ventilation output detection means of the ventilation device is communicated to the external device from the communication processing unit of the ventilation device. Then, when the external device determines whether or not the ventilation device is normal based on the actual ventilation output and determines that it is abnormal, it issues a reset command.
In other words, when the actual ventilation output communicated from the communication processing unit of the ventilator to the external device is extremely low, etc., it is determined that the ventilation control unit is not properly controlling the ventilation operation unit. In such a case, the external device issues a reset command.
By the way, when the reset processing unit of the ventilator is instructed to reset, it executes the reset process to reset the ventilation control unit, and as a result, the ventilation control unit malfunctioning causing freeze etc. It is as above-mentioned that it can eliminate.

Thus, based on the actual ventilation output of the ventilator, the abnormality of the ventilator is discriminated and the reset command is commanded. Therefore, the ventilation control unit is not properly controlled by the ventilation control unit. In the case where the actual ventilation output of the ventilation device is extremely insufficient, the ventilation control unit can be reset to eliminate the malfunction of the ventilation control unit.
In other words, in cases where the actual ventilation output of the ventilator is extremely insufficient, etc., avoiding continuing the operation processing of external equipment while the ventilation output is insufficient, and reducing the actual ventilation output of the ventilator. The operation processing of the external device can be executed with the ventilation output required.

  In short, according to the ninth feature configuration of the present invention, in addition to the operational effects of the eighth feature configuration described above, the ventilation system that can avoid continuing the operation process of the external device while the ventilation output is insufficient. Can provide.

The tenth characteristic configuration of the present invention, in addition to the ninth characteristic configuration,

The output is communicated from the communication processing unit to the external device.
The external device obtains the target ventilation output based on the operation status and the like.

When the actual ventilation output communicated from the communication processing unit of the ventilator is lower than the target ventilation output by a set value or more, the external device determines that the ventilator is abnormal and issues a reset command. Become.

In such a case, the external device issues a reset command.
In addition, when the reset processing unit of the ventilation device is instructed to reset, the reset processing for resetting the ventilation control unit is executed, and as a result, the malfunction of the ventilation control unit causing malfunction such as freezing. It is as above-mentioned that it can eliminate.

In this way, when the actual ventilation output of the ventilation device is lower than the target ventilation output by more than the set value, it is determined that the ventilation device is abnormal and a reset command is issued. If this control is not performed properly, it is possible to accurately detect that the actual ventilation output of the ventilator is lower than the target ventilation output and reset the ventilation control unit.
In other words, by comparing the actual ventilation output of the ventilator with the target ventilation output, it is possible to eliminate the malfunction of the ventilation controller by resetting the ventilation controller while accurately detecting the abnormality of the ventilator. .

  In short, according to the tenth characteristic configuration of the present invention, it is possible to provide a ventilation system capable of accurately detecting an abnormality of the ventilator and eliminating the abnormality in addition to the operational effects of the ninth characteristic configuration described above.

The eleventh characteristic configuration of the present invention, in addition to the tenth characteristic configuration,
When the actual ventilation output communicated from the communication processing unit is lower than the target ventilation output, but the external device is not lower than the set value, the external device is operated with the capacity corresponding to the actual ventilation output. It is characterized in that it is configured.

That is, when the actual ventilation output communicated from the communication processing unit of the ventilator is lower than the target ventilation output, but not lower than the set value, the external device will operate with the capacity corresponding to the actual ventilation output. .
In other words, when the actual ventilation output communicated from the communication processing unit of the ventilator is lower than the target ventilation output but not lower than the set value, the ventilation output of the ventilator is lower than the target ventilation output, but the external device Since the ventilation device is outputting the ventilation output that can continue the operation process, the operation process of the external device is continued.

Then, when the operation processing of the external device is continued, the actual ventilation output is lower than the target ventilation output, so the external device is operated with the capacity corresponding to the actual ventilation output.
For example, when the external device is a gas stove, the target ventilation output will increase or decrease depending on the total combustion amount of the gas stove, but the actual ventilation output is lower than the target ventilation output, so the combustion amount Is limited to the amount of combustion commensurate with the actual ventilation output.

  In this way, when the actual ventilation output communicated from the communication processing unit of the ventilator is lower than the target ventilation output, but not lower than the set value, the external device is operated with the capacity corresponding to the actual ventilation output. Thus, since the operation process of the external device is continued, it is possible to avoid stopping the operation process of the external device as much as possible and continue the operation process of the external device as much as possible.

  In short, according to the eleventh characteristic configuration of the present invention, in addition to the operational effects of the tenth characteristic configuration, it is possible to provide a ventilation system that can avoid stopping the operation processing of the external device as much as possible.

  Further, when a ventilation stop command is instructed from the stove control unit H, the ventilation control unit 22 transmits response information indicating that the ventilation stop command has been received, and then operates the electric motor 19 that drives the ventilation fan 20. Is configured to stop.

  Incidentally, in the present embodiment, since the ventilation air flow of the ventilation fan 20 is switched to two stages of “strong” and “weak”, the ventilation control unit 22 has the target ventilation air flow “weak” the ventilation fan 20. When the ventilation air volume is smaller than the ventilation air volume that is output when the ventilation fan 20 is operated, the ventilation fan 20 is operated with “weak”, and the target ventilation air volume is greater than the ventilation air volume that is output when the ventilation fan 20 is operated with “weak”. Is larger, the ventilation fan 20 is configured to operate at “strong”.

  In the present embodiment, the ventilation control unit 22 controls the operation of the ventilation fan 20 and the illumination lamp 21 based on the commands of the switches 23a to 23d in the manual operation unit 23 as described above. 20 (specifically, the electric motor 19), the command from the manual operation unit 23 and the command from the stove control unit H may overlap, but in such a case, the ventilation fan 20 The ventilation fan 20 is configured to be operated using a command on the side where the ventilation air volume is higher than the command to stop the command to operate the air.

The communication processing unit 18 on the gas stove side will be described. The transmission / reception circuit 18A includes a transmission buffer for storing transmission data instructed by the stove control unit H, a filter circuit for filtering reception data from the infrared port 18B, a transmission circuit A control circuit that modulates transmission data stored in the trust buffer, outputs the modulated data to the infrared port 18B, and demodulates the reception data output from the filter circuit, and a reception buffer that stores the demodulated reception data Has been.
The infrared port 18B is an infrared light emitting element, a drive circuit that drives the infrared light emitting element by an output from the transmission / reception circuit 18A, an infrared light receiving element, and an amplification that amplifies information received by the infrared light receiving element and outputs the amplified information to the transmission / reception circuit. A circuit is provided.

And the communication processing part 26 by the side of a ventilator is comprised similarly to the communication processing part 18 by the side of a gas stove.
That is, the transmission / reception circuit 26A modulates the transmission data stored in the transmission buffer storing the transmission data instructed from the ventilation control unit 22, the filter circuit filtering the reception data from the infrared port 26B, and the transmission buffer. The control circuit includes a control circuit that demodulates reception data that is output to the infrared port 26B and that is output from the filter circuit, and a reception buffer that stores the demodulated reception data.
The infrared port 26B is an infrared light emitting element, a drive circuit that drives the infrared light emitting element with an output from the transmission / reception circuit 26A, an infrared light receiving element, and an amplifier that amplifies information received by the infrared light receiving element and outputs the amplified information to the transmission / reception circuit. A circuit is provided.

When the infrared communication between the communication processing unit 18 on the gas stove side and the communication processing unit 26 on the ventilator side is described, in this embodiment, as a carrier wave (hereinafter referred to as a communication carrier), a frequency of 38 kHz Infrared rays having a duty ratio of 1/3 are used.
The format of communication between the communication processing unit 18 on the gas stove side and the communication processing unit 26 on the ventilation device side is as follows.
As shown in FIG. 5, the communication format is a format composed of “leader code”, “custom code”, “data code”, and “stop bit”.
FIG. 6 shows a data configuration indicating data “1” and data “0” in the communication format. In FIG. 6, the case where a communication carrier is present is indicated as on, and the case where no communication carrier is present is indicated as off.

The leader code in the communication format is defined such that the communication carrier on state continues for a period of 9 ms, and then the communication carrier off state continues for a period of 4.5 ms.
The reader code is a code in which a communication carrier continuously exists for the longest time in the communication format.

“Custom code” is 16-bit data assigned to each manufacturer.
In this embodiment, a continuous 16-bit code consisting of an 8-bit custom code and an 8-bit parity custom code obtained by inverting 1 and 0 of the 8-bit custom code is used as the custom code.

“Data code” is the data itself to be transmitted.
In this embodiment, continuous 16-bit data including an 8-bit data code and an 8-bit parity inverted data code obtained by inverting 1 and 0 of the data code is used.
In other words, this data code indicates that the ventilation start command, the ventilation stop command, the target ventilation air volume sent to the gas stove side ventilator side, or the ventilation start command sent from the ventilator side to the gas stove side is received. The response information shown, the response information showing that the ventilation stop command has been received, and the data code corresponding to the actual ventilation air volume are modulated and communicated between the gas stove A and the ventilation device D.

  Incidentally, in this embodiment, as can be understood from the above description, when instructing to operate the ventilation device D from the gas stove side, first, a data code for instructing a ventilation start command is transmitted, and then Thus, a data code for instructing the target ventilation air volume is transmitted.

  “Custom code” and “data code” include data of 0 and 1, but the distinction of 0/1 is simply 1 when the communication carrier is ON, and 0 when the communication carrier is OFF. As described above, as shown in FIG. 6, the communication carrier is turned off for a period of 1.69 ms after the communication carrier is turned on for 0.56 mS. 1 when the period until on is 2.25 ms), and after the communication carrier is turned on for 0.56 ms, the communication carrier is turned off for 0.565 ms (from the communication carrier on to the next on) The case where the period is 1.125 ms) is 0.

  Therefore, even when 1 is continuous, the communication carrier is not continuously turned on during that time, and even when 0 is continuous, the communication carrier is continuously turned off during that time. Therefore, by using a demodulation circuit with high detection accuracy of the presence / absence of a communication carrier, communication that is hardly affected by disturbance noise is possible.

  The “stop bit” is data used to identify whether the end of transmission data is 1 or the end of transmission data is 0.

As shown in FIG. 7, the ventilation device D is provided with a reset processing unit F that executes a reset process for resetting the ventilation control unit 22 by a reset command from the gas stove A as an external device.
That is, the reset processing unit F is configured to execute the reset process as a reset command from the gas stove A when the signal form of the transmission signal from the gas stove A received by the communication processing unit 26 is the signal form for reset request. Then, as a reset process, a reset signal is output to the reset input terminal E of the ventilation control unit 22.

In the present embodiment, the reset request signal form is such that the continuous existence time of the communication carrier is increased from the continuous communication carrier existence time for normal communication (the normal continuous carrier existence time for communication). Therefore, the communication carrier (carrier wave) is output.
That is, the communication format from the gas stove A is a code in which the carrier code is continuously present for the longest time in the communication format as described above, and the ventilation control unit 22 is reset. In this case, data (for example, 14 ms) in which the ON state of the communication carrier is longer than 9 ms is communicated from the gas stove A.

The reset processing unit F includes a 38 kHz filter circuit 30 and a 12 mS timer circuit 31 that outputs a reset signal when the continuous output time from the circuit 30 becomes 12 ms or longer.
That is, as shown in FIG. 8, in response to the output of the A section output from the infrared port 26B to the 38 kHz filter circuit 30, the B section signal is output from the 38 kHz filter circuit 30 to the 12 mS timer circuit 31, and the 12 mS timer circuit. 31 is configured to output a reset signal to the C section in accordance with the output of the B section.

  That is, when the continuous existence time of the carrier for transportation (carrier wave) is the time T1 shorter than the reference time T2 (12 mS), the reset output is not output, but the continuous existence time of the carrier for transportation (carrier wave) is the reference time T2. When the time T3 is longer than (12 mS), a reset signal is output to the C section.

In the present embodiment, when the gas stove A cannot receive response information from the ventilator D with respect to the communication of the command information for ventilation operation in the proper setting state, the reset command is commanded as an abnormality of the ventilator D. Is configured to do.
That is, as described above, the ventilation control unit 22 communicates response information for the ventilation operation command information from the gas stove A to the gas stove A from the communication processing unit 26. When the response information to the information communication cannot be received in the proper setting state, it is configured that the ventilation device D is abnormal and a reset command is issued.

  Specifically, when the response information transmitted from the ventilation control unit 22 when the ventilation start command is commanded from the stove control unit H is not the data of the appropriate setting state, the ventilation stop command is commanded from the stove control unit H Sometimes the response information transmitted from the ventilation control unit 22 is not the data of the proper setting state, and further, the information indicating the actual ventilation air volume transmitted from the ventilation control unit 22 is not the data of the proper setting state Is configured to command a reset command as an abnormality of the ventilation device D.

Further, when the gas stove A determines whether or not the ventilation device D is normal based on the actual ventilation air volume communicated from the communication processing unit 26 of the ventilation device D, the gas stove A is reset. It is comprised so that a command may be commanded.
That is, the ventilation control unit 22 obtains the actual ventilation air volume (actual ventilation output) output by the operation of the ventilation fan 20 as the ventilation operation unit based on the detection information of the rotational speed sensor 27 as the ventilation output detection means. Thus, as described above, the actual ventilation air volume is communicated from the communication processing unit 26 to the gas stove side, but the stove control unit H is based on the actual ventilation air volume communicated from the communication processing unit 26 of the ventilation device D. Thus, when it is determined whether or not the ventilation device D is normal, and it is determined that it is abnormal, a reset command is issued.

Specifically, when the stove control unit H commands the target ventilation air volume of the ventilation device D to the ventilation device D as described above, the ventilation control unit 22 causes the ventilation fan 20 to output the target ventilation air volume. The electric motor 19 for driving the fan 20 is controlled, and the actual ventilation air volume obtained based on the detection information of the rotational speed sensor 27 is communicated from the communication processing unit 26 to the gas stove side.
The stove control unit H is configured to determine that the ventilator D is abnormal when the actual ventilation air volume communicated from the communication processing unit 26 of the ventilator D is lower than the target ventilation air volume by a set value or more. .
Incidentally, in the present embodiment, when the actual ventilation air volume communicated from the communication processing unit 26 of the ventilation device D is lower than the target ventilation air volume by a set value or more, the actual ventilation air volume is less than half of the target ventilation air volume. It is.

  Further, the gas stove A, that is, the stove control unit H, sets the actual ventilation air volume when the actual ventilation air volume communicated from the communication processing unit 26 of the ventilation device D is lower than the target ventilation air volume but not lower than the above set value. The stove burner 1 and the grill burner 2 are configured to burn with a suitable capacity.

Incidentally, in the present embodiment, the actual ventilation air volume communicated from the communication processing unit 26 of the ventilation device D is lower than the target ventilation air volume when the actual ventilation air volume is lower than 95% of the target ventilation air volume. is there.
That is, when the actual ventilation air volume communicated from the communication processing unit 26 of the ventilation device D is lower than 95% of the target ventilation air volume and the actual ventilation air volume is higher than half of the target ventilation air volume, the actual ventilation air volume is set. The stove burner 1 and the grill burner 2 are burned with a suitable capacity (combustion amount).

Incidentally, the capacity (combustion amount) commensurate with the actual ventilation air volume can be obtained based on the ventilation air volume related information described above.
In other words, the ventilation air volume related information is information indicating the relationship between the target ventilation air volume and the sum of the combustion amounts of the three burners 1 and the grill burner 2, so that by replacing the target ventilation air volume with the actual ventilation air volume, 3 The sum of the combustion amounts of the two burners 1 and the grill burner 2 can be obtained, and the sum of the obtained combustion amounts is the combustion amount as an ability corresponding to the actual ventilation air volume.
That is, the sum of the combustion amounts required as the capacity corresponding to the actual ventilation air volume is the sum of the combustible combustion amounts for the three stove burners 1 and the grill burner 2.

  Moreover, in this embodiment, the stove control part H is until it can receive response information in a setting appropriate state, when the response information from the ventilation apparatus D with respect to communication of the ventilation operation command information cannot be received in a setting appropriate state. When the response information from the ventilator D cannot be received in the proper setting state even if the commanding the reset command is repeated twice, the control burner 1 and The combustion of the grill burner 2 is stopped, and communication with the ventilation device D is stopped.

  Further, in the present embodiment, the stove control unit H, when the actual ventilation air volume communicated from the communication processing unit 26 of the ventilation device D is less than or equal to half of the target ventilation air volume, the actual ventilation air volume is half of the target ventilation air volume. It is configured to repeat commanding a reset command until it becomes higher, and even if commanding the reset command is repeated twice, when the actual ventilation airflow does not become higher than half of the target ventilation airflow, Combustion of the stove burner 1 and the grill burner 2 is stopped, and communication with the ventilator D is stopped.

  The configuration in which the gas stove A commands the reset device to the ventilator D will be described. As shown in FIG. 4, when the stove control unit H commands the reset command, a transmission command (for example, 15 ms) is sent to the reset circuit Q. And a reset circuit Q outputs an output signal corresponding to a carrier for carrier having a frequency of 38 kHz and a duty ratio of 1/3 based on a transmission command from the stove control unit H for a set time ( For example, it is configured to output to the infrared port 18B for 15 ms).

In the present embodiment, there is provided a selection circuit P that selects the output signal from the reset circuit Q in preference to the transmission signal of the transmission / reception circuit 18A.
The selection circuit P includes a NOT circuit 32 that generates an inverted signal of a transmission command that the stove control unit H instructs the reset circuit Q, an AND circuit 33 that receives a signal from the NOT circuit 32 and a signal from the transmission / reception circuit 18A, In addition, an OR circuit 34 to which a signal from the AND circuit 33 and an output of the reset circuit Q are input is provided.

  That is, since the signal of the NOT circuit 32 is a low signal while the stove control unit H instructs the reset circuit Q to send a transmission command (for example, a high signal of 15 ms), the signal from the transmission / reception circuit 18A is The output signal from the reset circuit Q is output to the infrared port 18B without being output to the infrared port 18B.

Next, control operations of the stove control unit H and the ventilation control unit 22 will be described with reference to a flowchart.
First, the control operation of the stove control unit H will be described.
As shown in FIG. 9, when the stove control unit H is activated by turning on the power, it performs initialization processing such as turning off various control flags (# 1).

  Thereafter, input processing (# 2) for reading sensor information and the contents stored in the reception buffer of the transmission / reception circuit 18A, device control processing (# 3) for controlling the combustion operation of the stove burner 1 and the grill burner 2, and the ventilator D Transmission information setting process (# 4) for setting information to be transmitted to the receiver, reception content determination process (# 5) for determining data transmitted from the ventilator D, and transmission data set by the transmission information setting process are transmitted. The ventilation data transmission process (# 6) and the reset command transmission process (# 7) for transmitting the reset command to the ventilation device D are repeatedly executed.

Next, the input process of # 2 will be described.
As shown in FIG. 10, first, processing for reading detection information of sensors such as the fire extinguishing switch 14 and the rotary encoder 17 (# 11), and processing for reading data in the reception buffer of the transmission / reception circuit 18 (# 12) are sequentially executed. To do.

Next, if data is present when the reading process of # 12 is executed, whether the received data is in a proper setting state, such as whether the communication format of the read data is appropriate. (Whether or not the received data is normal) is determined (# 13). If the received data is not normal, the abnormality flag is turned ON (# 14), and then the apparatus control process (# 3) is performed.
If the data does not exist when the reading process of # 12 is executed, the process immediately shifts to the device control process (# 3), but the flow description is omitted in FIG. is doing.

  If it is determined to be normal in # 13, the process of storing received data (# 15) and the process of turning off the abnormality flag (# 16) are sequentially executed, and then the device control process (# 3) ).

Next, the device control process # 3 will be described.
As shown in FIG. 11, first, it is determined whether or not the stop flag set in the received content determination process of # 5 described in detail later is ON (# 21).
When the stop flag is ON, since the ventilator D is not operating properly, it is an abnormal state, and the stop process for stopping the combustion of the stove burner 1 and the grill burner 2 and the communication with the ventilator D is performed. (# 25), and further, a notification process for notifying an abnormality with an alarm lamp or alarm buzzer is executed (# 26).

If it is determined at # 21 that the stop flag is not ON, the actual ventilation air volume of the ventilator D (described as the received air volume in the drawing) is 95% of the target ventilation air volume (described as the ventilation air volume in the drawing). It is determined whether it is larger than (# 22).
When it is determined at # 22 that the actual ventilation airflow (received airflow) is greater than 95% of the target ventilation airflow (ventilation airflow), the burner 1 and the grill burner 2 are burned at the combustion amount commanded by the user. Unrestricted combustion control is executed (# 23). Thereafter, the process proceeds to the transmission information setting process (# 4).

When it is determined in # 22 that the actual ventilation airflow (received airflow) is not larger than 95% of the target ventilation airflow (ventilation airflow), the total combustion amount of the stove burner 1 and the grill burner 2 is Limited combustion control that restricts the combustion amount to the ventilation air volume is executed (# 24), and then the process proceeds to the transmission information setting process (# 4).
Incidentally, if the actual ventilation air volume (received air volume) is less than half of the target ventilation air volume (ventilation air volume), the stop flag is set to ON as will be described later, so this limited combustion control is executed. It will never be done. That is, in the limited combustion control, the actual ventilation air volume (received air volume) is lower than 95% of the target ventilation air volume (ventilated air volume), but the actual ventilation air volume (received air volume) is less than half of the target ventilation air volume (ventilatory air volume). It will be executed when it is high.

In the limited combustion control of # 24, as described above, the sum of combustible combustion amounts for the three burner burners 1 and the grill burner 2 as the capacity corresponding to the actual ventilation flow rate is obtained based on the ventilation flow rate related information. Thus, the combustion amounts of the stove burner 1 and the grill burner 2 are controlled so that the sum of the combustion amounts of the stove burner 1 and the grill burner 2 falls within the calculated sum of combustible combustion amounts.
In the case where the combustion amount of the stove burner 1 and the grill burner 2 is decreased, when both the stove burner 1 and the grill burner 2 are in combustion, the combustion amount of the stove burner 1 is decreased. When two or more of the two burners are combusting, the amount of combustion is reduced in the order of the small thermal power burner 1b, the standard burner 1a, and the high thermal power burner 1c.

Next, the transmission information setting process # 4 will be described.
As shown in FIG. 12, first, whether or not any of the three burner burners 1 and the grill burner 2 is burning, or whether or not an ignition process for the combustion is being performed, that is, the device It is determined whether it is in use (# 31).
If it is determined in # 31 that the device is in use, it is determined whether or not a ventilation start command has been issued (# 32). If the command has not been issued, a ventilation start command is issued to the ventilator D. Ventilation start command setting processing is set (# 33).

When it is determined in # 32 that the command has been issued, or after the ventilation start command setting process of # 33 is executed, a ventilation air volume calculation process for calculating the ventilation air volume is executed (# 34).
As described above, the ventilation air volume calculation process detects the combustion amount of each burner 1 and 2 based on the detection information of the rotary encoders 17 of the input operation units 10 to 13, and sums the detected combustion amounts. This is a process for obtaining the target ventilation air volume based on the sum of the obtained combustion quantities and the ventilation air volume related information.

After performing the ventilation air volume calculation process of # 34, it is determined whether or not the obtained ventilation air volume has changed from the previously obtained ventilation air volume (# 35). A ventilation air volume command setting process for setting the ventilation air volume to be commanded to the ventilator D is executed (# 36).
If it is determined in # 35 that there is no change, or after the ventilation airflow command setting process of # 36 is executed, the process proceeds to a reception content determination process (# 5).

If it is determined in # 31 that the device is not in use, it is determined whether or not a ventilation stop command has been issued (# 37). If not, it is determined whether or not 30 seconds have elapsed since the device was used. (# 38)
When 30 seconds have elapsed since the use of the device, a ventilation stop command setting process for setting the ventilation stop command to the ventilation device D is performed (# 39).

  If it is determined in # 37 that the command has been issued, if it is determined in # 38 that 30 seconds have not elapsed since the use of the device, and after executing the ventilation stop command setting process of # 39, # 5 shifts to the received content determination process.

  The ventilation air flow command setting process of # 36 is executed only when response information for the ventilation stop command is received in a proper setting state, and the ventilation stop command setting process of # 39 is appropriate for setting the response information for the ventilation stop command. This is executed only when information indicating the actual ventilation air volume as response information to the command of the target ventilation air volume is received in the appropriate setting state, but the flow description is omitted in FIG. ing.

Next, the received content determination process of # 5 will be described.
As shown in FIG. 13, first, it is determined whether or not it is the determination timing after the ventilation start command (# 41). This determination timing is stored in the reception buffer of the transmission / reception circuit 18A as response information from the ventilator D in the input process of # 2 after instructing a ventilation start command in the ventilation data transmission process of # 6. It is the timing immediately after reading the data from the existing ventilator D.

  When it is determined in # 41 that the determination timing is reached, it is determined whether or not the response from the ventilator D is normal depending on whether or not the abnormality flag set in the input process of # 2 is ON. (# 42).

If it is determined in # 42 that the response is not normal, a reset command setting process (# 43) for setting a command for a reset command to the ventilator D, and a counter addition process for adding a reset counter RC (# 44) ), A ventilation start command setting process (# 45) for setting to command the ventilation start command again is executed.
If it is determined at # 42 that the response is normal, a counter initialization process for initializing the reset counter RC to zero is executed (# 46).

When it is determined at # 41 that it is not the determination timing, after the counter initialization process of # 46 is executed, and after the ventilation start command setting process of # 45 is executed, the process proceeds to # 47. .
The process of # 47 is a process of determining whether or not it is the determination timing after the ventilation stop command. This determination timing is stored in the reception buffer of the transmission / reception circuit 18A as response information from the ventilator D in the input process of # 2 after instructing a ventilation stop command in the ventilation data transmission process of # 6. It is the timing immediately after reading the data from the existing ventilator D.

  If it is determined in # 47 that the determination timing is reached, it is determined whether or not the response from the ventilator D is normal depending on whether or not the abnormality flag set in the input process of # 2 is ON. (# 48).

If it is determined in # 48 that the response is not normal, a reset command setting process (# 49) for setting a command for a reset command to the ventilator D, and a counter addition process for adding a reset counter RC (# 50) ), A ventilation stop command setting process (# 51) for setting to command the ventilation stop command again is executed.
If it is determined at # 42 that the response is normal, counter initialization processing for initializing the reset counter RC to zero is executed (# 52).

If it is determined in # 47 that it is not the discrimination timing, or after the counter initialization process of # 52 is executed and the ventilation stop command setting process of # 51 is executed, the process proceeds to # 53. .
The process of # 53 is a process of determining whether or not it is the discrimination timing after the ventilation air volume command that commands the ventilation device D to the target ventilation air volume.
This determination timing is stored in the reception buffer of the transmission / reception circuit 18A as response information from the ventilator D in the input process of # 2 after instructing the target ventilation air volume in the ventilation data transmission process of # 6. It is the timing immediately after reading the data from the ventilation device D.

  When it is determined in # 53 that the determination timing is reached, it is determined whether or not the response from the ventilator D is normal depending on whether or not the abnormality flag set in the input process of # 2 is ON. (# 54).

  If it is determined in # 54 that the response is not normal, a reset command setting process (# 55) for setting a command for a reset command to the ventilator D, and a counter addition process for adding a reset counter RC (# 56) ), A ventilation airflow command setting process (# 57) for setting to command the target ventilation airflow again is executed.

When it is determined in # 54 that the response is normal, the actual ventilation air volume of the ventilator D (described as the received air volume in the drawing) is greater than half of the target ventilation air volume (described as the ventilation air volume in the drawing). (# 58), if it is determined not to be large, that is, if it is determined that the actual ventilation airflow (received airflow) is less than or equal to half of the target ventilation airflow (ventilatory airflow), then # 54 In the same manner as when the response is determined not to be normal, the reset command setting process (# 55), the counter addition process (# 56), and the ventilation air flow command setting process (# 57) are sequentially executed.
If it is determined at # 58 that it is large, that is, if it is determined that the actual ventilation air volume (received air volume) is greater than half the target ventilation air volume (ventilation air volume), the reset counter RC is initialized to zero. Counter initialization processing is executed (# 59).

When it is determined at # 53 that the determination timing is not reached, or after executing the counter initialization process of # 59 and after executing the ventilation air flow command setting process of # 57, the reset counter RC is 3. (# 60).
When it is determined at # 60 that the reset counter RC is 3, the ventilation device D is not operating normally even though the reset command is issued twice to the ventilation device D. Since the determination can be made, the above-described stop flag is turned ON (# 61).

  When it is determined at # 60 that the reset counter RC is not 3, or after the process of turning on the stop flag is executed at # 61, the process proceeds to the ventilation data transmission process of # 6.

Next, the ventilation data transmission process # 6 will be described.
As shown in FIG. 14, first, it is determined whether or not it is within a set time (for example, 5 seconds) after a reset command is issued by the reset command transmission process of # 7 (# 70).
That is, when the reset command is commanded to the ventilator D, it takes time until the ventilator D is reset and the normal operation state is started, so when the reset command is commanded to the ventilator D, It is determined whether or not the time required for the ventilation device D to rise to the normal operating state has elapsed.

In # 70, if it is determined that it is not within the set time (for example, 5 seconds) after the reset command is issued, the ventilation start command, the ventilation stop command, or the target ventilation air volume is commanded to the transmission / reception circuit 18A. A transmission data transmission process is executed (# 71).
Incidentally, the ventilation start command, the ventilation stop command, or the target ventilation ventilation air volume is set by the transmission information setting process of # 4 and the reception content determination process of # 5 as described above.

If it is determined in # 70 that it is within a set time (for example, 5 seconds) after the reset command is issued, or after the transmission data transmission process of # 71 is executed, the reset command transmission process of # 7 is performed. Will be migrated.
If there is no data to be transmitted when executing the transmission data transmission process of # 71, the process immediately proceeds to the reset command transmission process (# 3). In FIG. The description of the flow is omitted.

Next, the reset command transmission process of # 7 will be described.
As shown in FIG. 15, first, it is determined whether or not there is a reset command (# 81).
If it is determined in # 81 that there is a reset command, a reset command transmission process (# 82) for commanding a transmission command (for example, a 15 ms high signal) to the reset circuit Q, and a reset command The reset command release process (# 83) to be released is sequentially executed.

  If it is determined in # 81 that there is a reset command, or after executing the reset command canceling process in # 83, the process proceeds to the input process in # 2.

Next, the control operation of the ventilation control unit 22 will be described with reference to a flowchart.
As shown in FIG. 16, when the ventilation control unit 22 is activated by turning on the power, it executes initialization processing such as turning off various control flags (# 101).
Incidentally, the ventilation control unit 22 executes the initialization process (# 101) even when the reset signal from the reset processing unit F is input to the reset input terminal E as described above.

  Thereafter, an input process (# 102) for reading sensor information and the contents stored in the reception buffer of the transmission / reception circuit 26A, a ventilation control process for controlling the operation of the electric motor 19 for driving the ventilation fan 20 and the operation of the illumination lamp 2 (# 102). # 103) repeatedly executing the transmission information setting process (# 104) for setting the information to be transmitted to the gas stove A and the transmission process (# 105) for transmitting the transmission data set by the transmission information setting process Become.
