Description

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

  In recent years, cooking appliances have been used as cooking stoves such as boiled and fried foods, cooking stoves used for cooking foods such as meat and fish, and cooking stoves such as gas grills. A gas cooker has been proposed in which ventilation is performed in conjunction with a ventilation device (range hood) provided in a room (generally a kitchen) (see, for example, Patent Document 1).

  That is, the cooking device 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 cooking device that sends a wireless signal forward from a transmission unit provided on the front operation panel unit, at which time each operation for commanding heating or heating is performed, and a set time elapses from that time A transmission control unit for transmitting a radio signal corresponding to each operation from the transmission unit over a plurality of times with at least one point in time.

  In the case of the heating cooker of this patent document 1, according to use of the heating cooker which requires ventilation, it is automatically ventilated by the radio | wireless signal (for example, infrared signal) for ventilation operation sent out from a heating cooker. Since the apparatus operates, the combustion gas generated by using the heating cooker that requires ventilation is discharged to the outside from the room (generally the kitchen) where the heating cooker is installed. As a result, when the cooking device is used, it is possible to prevent the combustion gas and the like from being filled in the room where the cooking device is installed.

JP2013-044509A

  By the way, in many heating cookers that require ventilation, in particular, heating cookers (gas heating cookers) that use fuel gas as an energy source, dry batteries are used as the power source of the control means. Also, in the case of a gas heating cooker that uses a commercial power supply (AC100V) as a power source, a battery that can be used as a backup power source has become widespread so that it can be used even when the commercial power supply fails. ing.

  On the other hand, since the ventilator requires a commercial power source as a power source for the ventilation fan, it is normal that ventilation operation cannot be performed 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 wireless signal for starting ventilation operation (for example, an infrared signal) is sent from the device according to the use of the device, There will be a situation where the ventilator does not work.

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

  The present invention solves the above-mentioned problem, and when a power failure is restored when a signal for starting ventilation operation is sent from a device that requires ventilation (for example, a heating cooker) in the event of a power failure, An object of the present invention is to provide a ventilation device in which ventilation operation is started.

In order to achieve the above object, the ventilator of the present invention comprises:
A signal receiving unit that receives a communication signal transmitted from a device that requires ventilation, and a control unit that controls ventilation operation,
When the signal reception unit receives a ventilation operation start signal transmitted from the device, the control unit starts ventilation operation, and when the signal reception unit receives a ventilation operation stop signal transmitted from the device, the control A ventilator with a commercial power supply, the unit configured to stop ventilation operation,
A battery for supplying power to the control unit and the signal receiving unit during a power failure of the commercial power supply;
When the commercial power supply fails, after the signal receiving unit receives the ventilation operation start signal, the control unit starts the ventilation operation when the commercial power supply is restored and the commercial power supply is energized. It is characterized by

  In the ventilator of the present invention, when the commercial power supply is interrupted, the signal receiving unit receives the ventilation operation start signal, and then the commercial power supply is restored and the commercial power supply is energized. By the time, when the signal receiving unit receives the ventilation operation stop signal, the control unit is configured not to start the ventilation operation even if the commercial power supply is restored and the commercial power source is energized. It is preferable that

  The ventilator 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 a commercial power supply is interrupted. After receiving the start signal, when the power failure of the commercial power source is restored and the commercial power source is energized, the control unit is configured to start the ventilation operation. When a signal for starting a ventilation operation is sent from a device such as a gas heating cooker, the ventilation operation can be surely started when 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 is interrupted, the signal receiver receives the ventilation operation start signal and then the commercial power supply is restored after the commercial power failure is restored. If the control unit is configured not to start the ventilation operation even if the commercial power supply is restored and the commercial power supply is energized, an unnecessary ventilation operation may be performed. Can be prevented. 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 completed by the time of power recovery.

  In the present invention, there are no particular restrictions on the type of equipment that requires ventilation, but when the equipment that requires 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, and in the case of such a device, it is possible to realize reliable ventilation by applying the ventilation device of the present invention.

It is a perspective view of the gas stove used with the ventilator (range hood) concerning one Embodiment of this invention. It is a notch front view of the ventilation apparatus (range hood) concerning one Embodiment of this invention.
