Further, an air intake port 33 and an exhaust port 48 are opened to the vehicle room, and the opening of the cover 20 and the fitting and removal of the dust collecting unit such as the discharger 37 and the filter 31 is enabled to be carried out from the inside of the vehicle room. Thus, the maintenance of the filter 31 or the like can be easily carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to the structure of an on-vehicle air cleaner installed in the rear tray of an automobile.

BACKGROUND OF THE INVENTION In recent years, in-vehicle air purifiers that purify cigarette smoke and odors in automobiles have increased in number, and it has become common for them to be attached to the rear tray.

Conventionally, some of the vehicle air cleaners installed in the rear tray of this type are built in the trunk as shown in FIGS. 4 and 5.

Reference numeral 1 is a motor that drives a fan 2 attached to the main body of the vehicle air purifier, and 04, which is attached horizontally, is a filter bent like a folding screen. The main body is divided into a filter case 5 in which a filter 4 is placed and a whirlpool chamber 3 that covers a fan 2. Air sucked in through an intake port 6 is filtered for dust by the filter 4, passes through the whirlpool chamber 3, and is discharged from an exhaust lower. .

The main body is installed in the trunk of a car using metal fittings, and intake and exhaust air passes through a grill 9 installed in the rear tray of the car to purify the air inside the car.

Reference numeral 10 denotes a backing that connects the intake port 6, the exhaust lower and the grille 9 with each other in an air-tight manner.

Problems to be Solved by the Invention With this structure, when replacing the filter 4, it is necessary to open the trunk compartment and reach inside to replace it, which puts a burden on the work itself.

Furthermore, it is difficult to check the degree of contamination of the filter 4, so the filter 4 is used with reduced purification performance because the degree of contamination is not known, resulting in poor efficiency.

In addition, a backing 11 is required to communicate between the main body attached to the trunk and parts attached to the inside of the vehicle, making the construction and installation complicated.The present invention solves the above problem. The main unit is basically stored in the trunk, and parts that require maintenance, such as filters, can be replaced from inside the vehicle.

Additionally, the main unit can be installed and removed from inside the vehicle.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes a box body formed by a main body and a lid body, and a blower fan and a blower fan drive motor.
It has a built-in dust collection unit such as a fan chamber and a discharger and filter, and most parts of the main body are buried in the trunk, and the intake and exhaust ports are opened inside the passenger compartment. The dust unit is detachable from inside the vehicle when the lid is opened, and maintenance can be easily performed.

Further, the metal fittings for attaching to the vehicle body protrude from below from the vehicle body toward the main body, and after the main body is installed on the metal fittings, it can be fixed by tightening from above with a nut or the like.

Effects According to the above configuration, most of the air purifier body is buried in the trunk space under the rear tray, so the total thickness of the part that protrudes above the rear tray is low and does not obstruct rear visibility, yet it is easy to use for filter replacement, etc. Maintenance can be easily performed from inside the vehicle, making it possible to provide a highly practical in-vehicle air purifier. Furthermore, there is no need for parts that connect the main body and parts on the rear tray as in the prior art, making the configuration and installation simple.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

In FIGS. 1 to 6, the main body of the in-vehicle air purifier consists of a lower main body 21, an upper main body 22, and a lid 20.
There is an outer wall 25 hanging down from the top plate part 23, and a bottom plate part 26.
A fan chamber 27 is formed with a fan 29 fixed to a motor 28 fixed to the bottom plate part 26. The top plate portion 23 is provided with a suction port 30 and has supporting ribs 32 for supporting a flat filter 31 above. The upper body 22 is coupled to the lower body 21, and the lid 20 is detachably attached thereto.

A large number of slit-shaped intake ports 33 are provided in the lid body 20, and a discharge electrode 35 and a counter electrode 3 facing the discharge electrode 35 are provided below the intake port 33.
It holds a discharge device meter 7 consisting of 6. Both the discharger 37 and the filter 31 have a shape similar to a flat plate, are held horizontally, and can be attached and detached together when the lid body 20 is opened.

The filter 31 is formed by pasting together an electrostatic filter 38 and an activated carbon filter 39 incorporating activated carbon, and is inserted and removed from the side.

40 is a gas sensor that detects the degree of pollution of the air inside the vehicle. Reference numeral 41 denotes a printed circuit board to which the gas center 40 is attached, and a control circuit 42 controls the input of the motor 28 in accordance with the input of the gas sensor 40. gas sensor
40 mounting part forms a small chamber 44 by a protective wall 43 and is blocked from the air passage inside the main body, and smoke to the sensor is passed through the ventilation port 4.
Enter from 5.

A gas intake port 46 formed of a thin lattice is provided at a position facing the gas sensor 40 of the lid body 20, and the lattice of the intake port prevents large dust such as cotton waste from entering.

The small chamber 44 equipped with the gas sensor 40 presses one end of the filter and also serves as a guide for the filter.
Gas sensor 40 will be located near activated carbon filter 39.

Here, most of the lower body 21 is located in the rear tray 4 of the car.
7 and enters the trunk room, and the portion that emerges above the rear tray 47 has a low overall thickness.

48 is an exhaust port, and 49 is a rear window of the car.

Reference numeral 50 denotes a metal fitting for fixing the main body to the car, which protrudes downward from the car body. Then, it is passed through a screw hole 51 provided in the lower body and fastened with a nut 52 from above.

In the above configuration, when the motor 28 is driven, the intake port 33
The more air inside the car is sucked into the discharge electrode 35 and the counter electrode 3.
6, the particles are given positive ions and are electrically adsorbed by the rear electrostatic filter 38 with negative polarity, and odor particles are adsorbed by the activated carbon filter 39.

The clean air purified in this way passes through the fan chamber 29,
It is discharged into the vehicle from the exhaust port 48.

When replacing the filter 31 or removing the discharger 37 for cleaning, open the lid 20.
Work can be easily performed from inside the vehicle. It is also easy to check how dirty the filter is, and it is easy to prevent deterioration in cleaning performance due to dirt.

Even in the event of a breakdown, the main body can be easily removed compared to conventional models, making repairs easier.

However, most of the body is stored under the rear tray, so the overall thickness above the rear tray is low and does not block rear visibility.

Effects of the Invention As described above, according to the present invention, most parts of the air purifier body are stored in the trunk space under the rear tray, so the total thickness of the part that protrudes above the rear tray is low and does not obstruct rear visibility. However, maintenance such as filter replacement can be easily performed from inside the vehicle, making it possible to provide a highly practical in-vehicle air purifier. In addition, there is no need for parts to communicate between the main body and the parts on the rear tray as in the past, and the structure and installation are simple, so it has great practical value as an in-vehicle device.
