Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an on-vehicle air cleaner that is placed in the rear tray of an automobile and purifies the dirty air inside the vehicle.

2. Description of the Related Art Conventionally, this type of vehicle air cleaner has had a structure as shown in FIGS. 4, 6, and 6, for example. That is, as shown in the figure, a motor 3 for driving a fan 2 is built into the air purifier main body 1, and the motor 3 is held between a partition wall 6 and the purifier main body 1 via a support 1° frame 4. There is. Reference numeral 6 denotes a suction port opened in the inner wall 7 of the purifier main body 1, and a discharge device 9 is provided in the #1 air outlet 8 provided on the side of the purifier main body 1; A filter 10 bent into a V-shape is provided. A control circuit 11 is provided below the filter 10, and the motor 3
control. A metal shield plate 12 is formed to cover the control circuit 11. The filter 10 is formed by pasting together an electrostatic filter and an activated carbon filter incorporating activated carbon. 13 is a glint board on which a gas sensor 14 is mounted, and the control circuit 11 controls the input of the motor 3 based on the input of the gas sensor 14.
Although the mounting part of the gas sensor 14 is blocked from the air passage inside the main body by a protective wall 15, a vent hole 1 is provided between the partition wall 6 and the motor 3 so that the smoke from the gas sensor 14 enters through the ventilation window 16. , the air that has passed through the filter 10 is sent not only to the suction port 6 but also to the partition wall 6. ) and is also sucked into the fan 2 through the vent 17.

18 is an exhaust port, and 19 is a lid forming the upper part of the purifier main body 1.

In the above configuration, the air flow enters the purifier main body 1 through the intake port 8, fine dust is charged by the discharge device 9, and the fine dust is absorbed by the filter 10. The clean air that has passed through the filter 10 passes through the suction hole 61 and the vent 17, and is discharged to the outside from the exhaust port 18 by the fan 2.

The control circuit 11 controls the operating state of the motor 3 according to the output of the gas sensor 14, which changes depending on the smoke concentration inside the vehicle.

Problems to be Solved by the Invention In such a conventional car-mounted air purifier, a gas sensor 14 that detects changes depending on the concentration of smoke inside the car, that is, the degree of pollution of the air inside the car, is mounted on the car tray. 1, there is a problem in that the gas sensor 14 is located very far away from the driving force that increases the concentration of smoke inside the car, which has the highest probability of forming a cigarette film, and the detection of changes in concentration is slow. Ta.

The present invention solves the above problem, and aims to provide an on-vehicle air purifier that can start driving and purify the air inside the car the moment the driver is about to light a cigarette. There is.

Means for Solving the Problems In order to achieve the above object, the present invention provides a purifier body that includes a fan that purifies the air inside a car, a motor that drives the fan, and a remote control receiver that controls the motor. ,
Is there a signal in the remote control receiver? The wireless remote controller includes a remote controller having a remote control transmitter for transmitting data, and the wireless remote controller has an infrared sensor for detecting infrared rays and is disposed near the front of the driver.

Effect With the above-mentioned configuration, the moment the driver tries to light a cigarette, the infrared sensor detects the red hot part of the lighter, etc., and the transmitting section sends the detection signal to the remote control receiving section of the rear tray. Drive and control.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1, 2, and 3. Note that parts that are the same as those in the conventional example are given the same reference numerals and their explanations will be omitted. In the figure, 20
is a wireless remote control that is attached near the front of the driver's seat and controls the operation of the air purifier body 1 in the rear tray.
The device includes an infrared sensor 21 for detecting infrared rays and a remote control transmitter 22 for transmitting this signal to a remote control receiver 23. A remote control receiver 23 disposed on the front surface of the purifier body 1 receives a transmission signal from the wireless remote controller 2o and sends it to the control circuit 11.

With the above configuration Q, when the driver sitting in the driver's seat tries to light a fire pit, the infrared sensor 21 built into the wireless remote control 20 detects the red-hot part of the torch, lighter, etc. is transmitted from the remote control transmitter 22,
The remote control receiver 23 on the front side of the purifier body 1 in the rear rear tray receives the detection signal, and the purifier body 1 starts operating under the operation control of the control circuit 11, and the air inside the car is purified. In this way, the air purifier can start operating the moment the driver tries to light a cigarette, cleaning the air inside the car before cigarette smoke stains stick to the interior walls etc. It is something that can be done.

Effects of the Invention As is clear from the above description of the embodiments, the in-vehicle air purifier of the present invention has a wireless remote control that operates the air purifier itself (by installing it near the front of the driver's seat). , the moment the driver tries to light a cigarette, it detects the red hot part of the lighter, etc., and sends a sway detection signal to the air purifier in the rear tray using the wireless remote control, causing it to operate and control. The moment the driver is about to light a cigarette, the air purifier starts operating and purifies the air inside the car.
