Abstract

PURPOSE:To provide a ventilator, ventilating a room quickly so as not to fill the room with gas and capable of providing a comfortable room. CONSTITUTION:The main body 2 of a ventilating fan is installed on the wall surface 1 of a room and a receiving unit 3, receiving a signal, is provided at the lower part of the main body 2 of the fan while a gas sensor 7, detecting gas, and a switching unit 8, for controlling the main body 2 of the ventilating fan, are provided on the main body 4 of a remote controller. Further, a transmitting unit 9, transmitting the signals of the gas sensor 7 and the switching unit 8 to the main body 2 of the ventilating fan, is provided on the remote controller.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation device provided with a remote controller for remotely controlling a ventilation fan.

[0002]

2. Description of the Related Art In recent years, a ventilation fan that automatically operates with a gas sensor has a gas sensor attached to the ventilation fan body.
It was common to start driving when gas was detected when smoking a cigarette.

The structure of a conventional ventilation fan with a gas sensor of this type will be described with reference to FIGS.

As shown in the figure, the blade 101 is provided on the box-shaped outer shell.
An electronic circuit unit 106 having a gas sensor 105 is provided inside a ventilation fan body 104 provided with a shutter 102 and a motor 103.

[0005]

In such a conventional ventilation fan with a gas sensor, since the ventilation fan main body 104 is attached to the ceiling or the wall, the distance from the gas sensor 105 to the source of cigarette smoke is large. There is a problem that it takes time to detect it, and even if a cigarette is smoked, it takes time to start the operation of the ventilation fan, and the air in the room becomes bad.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a ventilator capable of making a comfortable room by detecting a gas sensor immediately after smoking a cigarette and operating a ventilation fan. And

[0007]

In order to achieve the above-mentioned object, a ventilator according to the present invention is provided with a ventilating fan provided with a receiving part and a transmitting part for transmitting to the receiving part of the ventilating fan to control the operation of the ventilating fan. The remote controller and a gas sensor provided in the remote controller are provided, and the remote controller detects gas to automatically operate the ventilation fan.

[0008]

According to the present invention, when a person smokes a cigarette, the gas sensor built in the remote control at hand detects gas quickly and sends a signal to start the operation to the ventilation fan body so that quick ventilation can be achieved. It will be possible.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIG.

As shown in the drawing, a ventilation fan main body 2 is installed on a wall surface 1 of a room, and a receiving portion 3 for receiving a signal is provided below the ventilation fan main body 2. On the remote control body 4 side, a power supply section 5 and a control section 6 for controlling the remote control body 4 are provided.
And a gas sensor 7 for detecting gas in the control unit 6.
And a switch section 8 for controlling the ventilation fan main body 2, the gas sensor 7 and the switch section 8
A transmission unit 9 for transmitting the signal of (1) to the ventilation fan main body 2 is provided.

In the above structure, when the power of the remote controller main body 4 is supplied from the power source section 5 provided in the remote controller main body 4 and a person smokes a cigarette, the gas sensor 7 built in the remote controller main body 4 which is at hand is a gas. Is detected, the control unit 6 sends the signal to the receiving / transmitting unit 9, and the transmitting unit 9 sends the signal to the ventilation fan main body 2 installed on the wall surface 1. The receiving unit 3 receives the signal and the ventilation fan starts operation. Quick ventilation is possible. Further, by pressing the switch section 8 of the remote controller main body 4, the control section 6 sends a command to the transmitting section 9 to send the command from the transmitting section 9 to the receiving section 3 provided in the ventilating fan main body 2. Can be controlled.

[0012]

As is apparent from the above embodiments, according to the present invention, since the gas sensor is provided in the remote controller for operating the operation of the ventilation fan, the remote controller at hand can quickly detect the gas, so that quick ventilation can be achieved. It becomes possible to provide a ventilator capable of obtaining a comfortable room that is not filled with gas even when smoking a cigarette.
