BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle air cleaning device installed in an instrument panel of an automobile.

[0002]

2. Description of the Related Art An outside air intake is provided in a cowl top cover of an automobile, and the outside air taken in from the outside air intake or the inside air circulated in a vehicle cabin is driven by a driving force of a fan motor provided inside an instrument panel. 2. Description of the Related Art As a conventional air supply device for blowing air into a vehicle cabin, there is one having a structure as shown in FIG.

[0003] That is, 1 is a cowl top cover of an automobile.
The inside / outside air intake duct 3 communicates with the inside / outside air intake duct 3, and an inside / outside air switching door 4 is provided at a substantially intermediate portion of the inside / outside air intake duct 1.
The fan motor 5 is provided at the tip of the. Reference numeral 6 denotes an instrument panel provided in the vehicle interior, and reference numeral 7 denotes a glove box.

In the air supply apparatus having such a structure, the outside air intake and the inside air circulation can be selectively performed by operating the inside / outside air switching door 4 described above. Since the supply device was not provided with a dust collecting filter, a deodorizing filter, and the like, it was not possible to obtain a dust collecting function and a deodorizing function particularly when taking in outside air.

[0005] Therefore, in the air supply device incorporated in the instrument panel, a vehicle air purifying device which is provided with a filter unit for collecting and deodorizing dust so as to purify air can be provided. The application was filed on July 1, 2 years.

The air purifier of the prior application has a structure shown in FIG. 2, in which 11 is a windshield of an automobile, 12 is an instrument panel provided inside and outside the vehicle interior from the windshield 11, and 13 is an instrument panel. It is an outside air intake hole provided in the cowl top cover of the car. Reference numeral 14 denotes an air duct provided in the inner part of the instrument panel 12, and the air duct 14
An outside air inlet 15 for taking in outside air through the opening 3 is opened, and the inside air inlet 1 is provided in the air duct 14 for taking in the air inside the vehicle and located near the outside air inlet 15.
6 is open. Reference numeral 24 denotes an inside air / outside air switching door. When the inside air / outside air switching door 24 closes the outside air intake 15, the inside air circulates, and when the inside air outside air intake 16 is closed, outside air is introduced. Reference numeral 17 denotes a bypass duct which is provided in the air duct 14 and extends substantially horizontally toward the interior of the vehicle. A filter unit 18 including a filter and an activated carbon filter is held, and the filter unit 18 is provided detachably from the vehicle interior. The bypass duct 17 is connected to the filter unit 1.
8, the air inlet side passage 20 and the air outlet side passage 21 are divided into two sections.
Door 25 is provided, and a second door 26 is provided at an outlet of the air outlet side passage 21. Both doors 25, 26
Are interlocked with each other by operation in the vehicle interior.

Reference numeral 29 designates the air introduction side passage 20 vertically
The flow control plate 29 is held so as to face the filter unit 18 so as to be divided. The flow control plate 29 has a width gradually increasing in the air flow direction (in the vehicle compartment) as shown in FIG. 3, for example. A thick hole 30 is provided.

Reference numeral 22 denotes a blower case integrally formed with the air duct 14. A fan 23 is provided in the blower case 22, and the blower case 22 extends toward the vehicle interior from the position of the fan 23. And is divided into left and right to form a T-shape to send air into the vehicle interior.

Reference numeral 27 denotes a glove box located below the bypass duct 17, and reference numeral 28 denotes a cover of the glove box 27.

[0010]

However, in the air purifying apparatus of the prior art, the air introduction side passage 2 is provided.
0 and the first for opening and closing each of the air outlet side passages 21.
It is necessary to provide a duct space for vertically arranging the door 25 and the second door 26 side by side, and in particular, by operating the second door 26, air that passes or does not pass through the filter unit 18 is introduced into the blower case 22. Since the air duct 14 for feeding the air is required, it is difficult to set the opening of the inside air inlet 16 large, and there is a problem that the amount of circulating air of the inside air circulating air is insufficient.

[0011]

SUMMARY OF THE INVENTION In order to solve the problem in the prior art, the present invention solves the problem in the second embodiment.
Another object of the present invention is to provide an air purifying apparatus for a vehicle in which the diameter of the inside air inlet is enlarged by improving the door structure of the vehicle, thereby obtaining a sufficient amount of inside air circulating air.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in FIGS. 3 and 4. The same parts of the structure of the present embodiment and the structure described in the conventional example are used in the conventional example. The same reference numerals are given and the description of the same structural parts is omitted.

That is, in the present embodiment, the partitioning position of the tip end of the filter unit 18 that divides the air inlet side passage 20 and the air outlet side passage 21, and the intake air provided in the blower case 22. A louver-type shutter 32 is arranged between the lip of the mouth 31 and the air introduction side passage 2.
0 and the air outlet side passage 21. As shown in FIG. 4, the louver-type shutter 32 has a structure in which a plurality of louver blades 35 are rotatably supported in parallel and rotatably between frame walls of an opening 34 of a flat frame 33 facing each other. is there. Each louver blade 35 is linked in a fan shape by a driving means (not shown) to open and close the opening 34.

As described above, the louver-type shutter 32 is interposed between the air moving-in side passage 20 and the air moving-out side passage 21 which are separated from each other by the filter unit 18 as a boundary.
By the operation of the louver type shutter 32, the air introduction side passage 2 is formed.
The louver-type shutter 32 is provided so that the fan-shaped operation space of the blade 35 can be narrowed. Therefore, a large fan-shaped rotation space of the inside / outside air switching door 24 for opening and closing the inside air intake 16 can be ensured by that much, whereby the diameter of the inside air intake 16 is widened and a large amount of inside air circulation is performed. Air can be obtained.

[0015]
