Description

  The present invention relates to a ventilator, and more particularly, to a ventilator used with, for example, cooking equipment.

  In recent years, heating cookers have been used as cooking stoves for cooking cooked foods such as boiled and fried foods, and for cooking foods such as meat and fish, and as cooking appliances such as gas grills. 2. Description of the Related Art A gas cooker has been proposed in which a ventilation device (range hood) provided in a room (generally a kitchen) is linked to perform ventilation (for example, see Patent Document 1).

  That is, the heating cooker of Patent Document 1 controls driving or stopping of an exhaust device that discharges 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 a wireless signal forward from a transmission unit provided on a front operation panel unit, and a time when each operation for instructing heating or a heating stop is performed, and a set time elapses from the time. A transmission control unit that causes the transmission unit to transmit a wireless signal corresponding to each operation a plurality of times at least at one time point within the period up to.

  In the case of the heating cooker of Patent Document 1, ventilation is automatically performed by a wireless signal (for example, an infrared signal) for starting a ventilation operation sent from the heating cooker according to the use of the heating cooker that requires ventilation. Since the device operates, combustion gas and the like generated by use of the cooking device requiring ventilation are discharged to the outside from a room (generally a kitchen) in which the cooking device is installed. As a result, when the cooking device is used, it is possible to prevent the room where the cooking device is installed from being filled with combustion gas or the like.

  By the way, in a heating cooker requiring ventilation, especially a heating cooker (gas heating cooker) using fuel gas as an energy source, a dry battery is often used as a power source of the control means. Also, in the case of a gas heating cooker using a commercial power supply (AC100V) as a power source, a device configured to use a dry battery as a backup power source has become widespread so that it can be used even in the event of a commercial power failure. ing.

  On the other hand, a ventilator requires a commercial power supply as a power source of a ventilation blower, and thus cannot normally perform a ventilation operation during a power failure.

  Therefore, when using a device such as a gas heating cooker that requires ventilation at the time of a power failure, even if a radio signal (for example, an infrared signal) for starting a ventilation operation is transmitted from the device in accordance with the use of the device, A situation may occur in which the ventilator does not work.

  By the way, long-term power outages rarely occur in Japan, and in many cases power is restored in a very short time.However, if gas equipment is used during a power outage, ventilation is required, for example, gas heating cooking Since the ventilator cannot receive a wireless signal (for example, an infrared signal) transmitted from a device such as a vessel, the ventilator does not operate even when power is restored, and there is room for improvement.

  The present invention has been made to solve the above problems, and when a signal for starting a ventilation operation is transmitted from a device requiring ventilation (for example, a cooking device) at the time of a power failure, when power is restored, reliable It is an object of the present invention to provide a ventilation device in which ventilation operation is started.

To achieve the above object, the ventilation device of the present invention
A signal receiving unit that receives a communication signal transmitted from a device requiring ventilation, and a control unit that controls ventilation operation,
When the signal receiving unit receives a ventilation operation start signal transmitted from the device, the control unit starts the ventilation operation, and when the signal receiving unit receives a ventilation operation stop signal transmitted from the device, the control unit starts the ventilation operation. A ventilator powered by commercial power, wherein the unit is configured to stop ventilation operation,
A battery that supplies power to the control unit and the signal receiving unit during a power outage of the commercial power supply,
At the time of the power failure of the commercial power source, after the signal receiving unit receives the signal for starting the ventilation operation, when the power failure of the commercial power source is restored and the commercial power source is energized, the control unit starts the ventilation operation. It is characterized by

  Further, in the ventilator of the present invention, at the time of the power failure of the commercial power, after the signal receiving unit receives the signal for starting the ventilation operation, the power failure of the commercial power is restored and the commercial power is supplied. By the time, if the signal receiving unit receives the ventilation operation stop signal, the control unit does not start the ventilation operation even if the power supply of the commercial power supply is restored and the commercial power supply is turned on. It is preferred that

  The ventilation device of the present invention is configured as described above, and includes a battery that supplies power to the control unit and the signal receiving unit when the commercial power supply fails, and when the commercial power supply fails, the signal receiving unit performs the ventilation operation. After receiving the start signal, when the power supply of the commercial power supply is restored and the commercial power supply is energized, the control unit is configured to start the ventilation operation. When a signal for starting the ventilation operation is transmitted from a device such as a gas heating cooker, the ventilation operation can be reliably started when the power is restored. As a result, a highly reliable ventilation device can be realized.

  Further, in the ventilator of the present invention, when the commercial power supply fails, after the signal receiving unit receives the ventilation operation start signal, the signal receiving unit is restored until the commercial power supply is restored and the commercial power supply is energized. If the control unit is configured not to start the ventilation operation even if the power supply of the commercial power supply is restored and the commercial power supply is turned on when receiving the ventilation operation stop signal, unnecessary ventilation operation may be performed. Can be prevented. Note that such an aspect is significant when the use of a device that requires ventilation is started at the time of a power failure of the commercial power supply and the use of the device that requires ventilation is finished before the power is restored.

  In the present invention, there is no particular limitation on the type of equipment requiring ventilation, but when the equipment requiring ventilation is, for example, a gas heating cooker or a gas water heater, a large amount of combustion exhaust gas is generated. Therefore, it is preferable that appropriate ventilation is reliably performed. In such a case, by applying the ventilation device of the present invention, reliable ventilation can be realized.

An infrared signal for starting operation is transmitted, and the use of the gas stove 100 is terminated (from the state in which heating is performed by the stove burner 1 or the state in which heating is performed by the grill burner, both the stove burner 1 and the grill burner have stopped heating). A signal transmission unit 100 </ b> S that transmits an infrared signal for stopping the ventilation operation to the ventilator (range hood) 110 is provided along with the transition to the above.

<Ventilation system (range hood) configuration>
The ventilation device (range hood) 110 (see FIG. 2) according to the embodiment of the present invention used together with the gas stove 100 is installed in the kitchen together with the gas stove 100. As a power supply for operating the range hood 110, a commercial power supply (AC100V) is used.

  The range hood 110 includes an exhaust fan 101, a motor 107 for driving the exhaust fan 101, a hood 103 serving as a suction port for air in the kitchen, and an exhaust duct 106. Then, by energizing the motor 107 for driving the exhaust fan 101 and driving the exhaust fan 101, the air in the kitchen sucked from the hood 103 is discharged to the outside of the kitchen via the exhaust duct 106. It is configured to be discharged.

  Generally, an extension exhaust pipe (not shown) or the like is connected to the exhaust duct 106 of the range hood 110, and the air in the kitchen sucked from the hood portion 103 of the range hood 110 is supplied from the exhaust duct to the extension duct. After being exhausted, it is discharged outside the kitchen.

  Also, when the signal receiving unit 200S receives the infrared signal for stopping the ventilation operation during the execution of the ventilation operation in which the exhaust fan 101 is driven, the control unit (not shown) controls the motor for driving the exhaust fan 101. The energization of the exhaust fan 107 is stopped, the driving of the exhaust fan 101 is stopped, and the ventilation operation is stopped.

<Characteristic configuration>
Next, a characteristic configuration of the ventilation device according to the embodiment of the present invention will be described.

  The above described range hood 110 includes a battery (not shown). The battery is configured to be charged by a commercial power supply (AC 100 V) that is a power supply of the range hood 110.

  When a commercial power supply fails, power is supplied from the battery to the control unit and the signal receiving unit 200S (not shown).

  When the signal reception unit 200S of the range hood 110 receives the infrared signal for starting the ventilation operation transmitted from the signal transmission unit 100S of the gas stove 100 at the time of the power failure of the commercial power supply, the control unit (not shown) issues a ventilation operation request. Set the flag F = 1.

  When the signal reception unit 200S of the range hood 110 receives the infrared signal for stopping the ventilation operation transmitted from the signal transmission unit 100S of the gas stove 100 at the time of the power failure of the commercial power supply, the control unit (not shown) issues a ventilation operation request. Set the flag F = 0.

  Then, when the ventilated operation request flag F = 1, when the commercial power supply that has been out of power is restored, and the commercial power supply (AC 100 V) is supplied to the range hood 110, the control unit (not shown) starts exhausting. By energizing the motor 107 for driving the fan 101 and driving the exhaust fan 101, the ventilation operation is started.

  Further, when the ventilation operation request flag F = 0, the control unit (not shown) also operates when the commercial power supply that has been out of power is restored and the commercial power supply (AC 100 V) is supplied to the range hood 110. Since the motor 107 for driving the exhaust fan 101 is not energized and the stop of the exhaust fan 101 is maintained, the ventilation operation is not started.

  By providing the above-described configuration, when an infrared signal for starting the ventilation operation is transmitted from a device requiring ventilation (the gas stove 100 in this embodiment) at the time of a power failure, when the commercial power supply is restored from the power failure, Thus, a highly reliable ventilator (range hood) 110 that reliably starts the ventilation operation can be realized.

  Further, during the power failure, after an infrared signal for starting the ventilation operation is transmitted from a device requiring ventilation (the gas stove 100 in this embodiment) until the commercial power supply (AC100V) is restored from the power failure and is energized. When an infrared signal for stopping the ventilation operation is transmitted from a device requiring ventilation (the gas stove 100 in this embodiment), the ventilation operation is not started even if the commercial power supply (AC 100 V) is restored. Since it is configured, unnecessary ventilation operation is not performed, and energy saving can be realized.

  During a power outage, if an infrared signal for ventilating operation is sent from a device that requires ventilation, and then an infrared signal for stopping ventilation operation is sent from the device until commercial power is restored. The configuration for preventing the ventilating operation from starting even when the commercial power supply is restored is an arbitrary configuration, and it is possible not to provide this configuration.
