Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an air purifier that is installed in an automobile, particularly in the ceiling of a vehicle interior.

Conventionally, this type of air purifier has been equipped with a room lamp in the air purifier body to illuminate the interior of the vehicle, and as shown in the conventional example in Fig. , on the outlet C side,
A lamp housing H was provided between a blower D consisting of a motor F and a fan E, and a room lamp I was formed on the vehicle floor side of the air purifier body A.

However, in the above-mentioned conventional type, the room lamp is located between the dust collection filter and the blower on the suction side, which not only adds resistance to the air flow, but also takes up the room lamp space between the dust collection filter and the blower. It has the disadvantage that it only illuminates a portion of the vehicle interior, and if the room lamp space were to be expanded, the length of the air purifier body would have to be increased, which would increase the weight. This causes the inconvenience of doing so. Furthermore, since the motor and the room lamp are separated from each other, there is also the drawback that the work of connecting electrical wiring inside the air purifier body is complicated.

The present invention was made in order to eliminate the above-mentioned conventional drawbacks, and a room lamp lens is provided flush with the protruding surface of the air purifier body that protrudes toward the vehicle floor, and on the back of this room lamp lens, At the same time as positioning the printed circuit board on which the light bulb is directly mounted, insert the blower motor located at the back of the printed circuit board into the hole drilled in the printed circuit board, and cover the bottom of the motor that protrudes downward and the motor wiring. It is an object of the present invention to provide an air purifier that is attached to a printed circuit board, so that it can be made thinner and smaller, and it can also save labor in connecting electrical wiring.

Next, the present invention will be explained in detail based on an embodiment shown in FIGS. 2 and 3.

In the figure, 1 is the main body of an automotive air purifier that is attached to the ceiling of the vehicle interior, which sucks in dirty air from the interior of the vehicle through an intake port 13 and blows purified air into the vehicle interior through an outlet 14. .

Reference numeral 2 denotes a filter unit installed behind the suction port 13, which collects dust charged by the ionized beam 16 and the counter electrode 17 irradiated at the back of the suction port 13, and also deodorizes the sucked air. It is also something that is done.

3 is a blower, a fan case 5 with a vent
A fan 4 that rotates horizontally is housed in the fan case 5, and a motor 6 for driving the fan 4 is housed in the fan case 5.
It is screwed to the A room lamp 7 is formed below the blower 3.
The room lamp 7 includes a room lamp lens 1 provided flush with the protruding surface of the air purifier body 1 on the vehicle floor side.
1, and a printed circuit board 9 located at the back of the room lamp lens 11 and on which a plurality of light bulbs 8 are directly disposed. A hole 10 is bored in the center of the printed circuit board 9, and the motor 6 of the blower 3 is inserted into the hole 10 so that the bottom of the motor 6 protrudes. Then, a cover 12 covering the protruding bottom of the motor 6 and the motor wiring connected to the printed circuit board 9 is attached to the claw 1.
By engaging the motor 2' in the recess 10' of the notch of the hole 10, the motor 6 is attached to the printed circuit board 9 and is prevented from being seen through the room lamp lens 11. The room lamp lens 11 has a plurality of claws 11' provided on the left and right sides of the air purifier body 1.
By locking into the mounting groove 15 provided in the
It is attached flush with the protruding surface of the air purifier body 1 on the vehicle floor side. The room lamp lens 11 can also make the cover 12 invisible from the outside by the design of the lens cut.

Therefore, according to the present invention, a room lamp is formed by a room lamp lens that is flush with the protruding surface of the air purifier body protruding toward the passenger compartment, and a printed circuit board located behind the room lamp lens and on which a light bulb is directly attached, and the blower motor located above the room lamp is inserted through a hole in the printed circuit board, so that a larger room lamp space can be secured on the protruding surface of the air purifier body on the vehicle floor side compared to conventional products, and the height dimension of the air purifier body can be set without being restricted by the shape of the room lamp, and since the blower and room lamp are arranged vertically, the length dimension of the air purifier body can also be made smaller than conventional products, resulting in a compact air purifier with a large room lamp space.In addition, since the motor is close to the printed circuit board, it is easy to connect the electrical wiring, which saves labor in connecting the light bulb and the motor, and the position of the light bulb can be freely set, providing excellent practical effects.
