JPH10113521A - Automotive cabin filter - Google Patents

Abstract

PROBLEM TO BE SOLVED: To remove dust contained in air flowing into an automotive cabin and at the same time, deodorize the air by arranging a filtration part through which dust is filtered and a honeycomb deodorizing part in parallel in an almost square casing. SOLUTION: A filtration part 2 housed in a casing 1 consists of a filter member 7a which is formed by folding an electrostatic nonwoven fabric in bellows shape on the upstream side and is bonded airtightly to the long lateral part 5 of the casing 1. In addition, one of both end faces 7 of the filter member 7 is bonded to the short lateral part 6 of the casing 1 and the other end face 7 is bonded to a partition part 4. Further, a honeycomb-type deodorizing part 3 is held by adhesion on the long lateral part 5, the short lateral part 6 and the partition part 4 of the casing 1, and the deodorizing part 3 is installed side by side with the filtration part 2. Consequently, it is possible to perform dust removing and deodorizing operations simultaneously and thereby prevent the inflow of air in an automotive cabin from deteriorating without the replacement of a clogged filter for a new one and also the performance of the filter from falling down.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter for removing dust and deodorizing air in a vehicle.

[0002]

2. Description of the Related Art Recently, dust and dirt are contained in the air of a traveling road.
In particular, there is a lot of carbon particles and at the same time a strong odor,
Not only does the air taken into the vehicle interior mix carbon particles and odors, making the driver uncomfortable, but also contaminating the interior of the vehicle. In many cases, this type of filter is attached to a place where air is introduced into the interior of a vehicle through a cooling / heating device, which is an air conditioner for the vehicle.

As a filter for an air conditioner for a vehicle, for example, there is a filter disclosed in Japanese Patent Application Laid-Open No. 7-76212. In the filter disclosed in this publication, a filter is provided which is always open to bypass the filter member and allow air to flow therethrough. A bypass passage is provided.

[0004]

However, in the filter disclosed in the above publication, no measures are taken for deodorizing the air taken into the vehicle interior, and when the filter member is clogged, There is a drawback in that there is an opening through which air can be taken in from the bypass passage without taking any measures.

The present invention solves the above problems,
The purpose is to provide an automobile in which a coarse honeycomb-shaped deodorizing material is provided in parallel with the filtering unit as a bypass means when the filtering member is clogged, while performing deodorization simultaneously with dust removal of air flowing into the vehicle interior. An object of the present invention is to provide an indoor filter.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a filter provided in a passage for taking in air into a vehicle interior and removing dust and odor in the air passing through the passage. A filter portion for filtering dust and a honeycomb-shaped deodorizing portion are installed in parallel in a substantially square casing.

According to the filter for a vehicle interior having the above-described structure, the honeycomb-shaped deodorizing section is provided in parallel with the filtering member for removing dust such as carbon particles, so that dust removal and deodorization can be performed simultaneously. When the filter member is clogged, the honeycomb-shaped deodorizing section acts as a detour,
The function of removing coarse dust and deodorizing can be achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an assembled partial cross-sectional view of a vehicle interior filter according to a first embodiment of the present invention, and FIG. 2 is an assembled partial cross-sectional view of an automobile interior filter of the second embodiment.

A filter for a vehicle interior according to a first embodiment shown in FIG. 1 has a substantially rectangular casing 1 formed of an iron plate or a plastic material, and a filter formed by folding the casing 1 in a bellows shape. Part 2 and honeycomb-shaped deodorizing part 3
Are installed in parallel via the partition 4.

The casing 1 has a long side portion 5 and a short side portion 6. The filtering section 2 has a filter member 7 formed in a bellows shape on the upstream side by folding it with a material such as an electrostatic non-woven fabric, and both side surfaces 7a of the filter member 7 are air-tightly bonded to the long side surface portion 5 of the casing 1. One end is bonded to the short side surface 6 of the casing 1, and the other end 7 b is bonded to the partition 4.

Further, on the downstream side, both side surfaces 8a of the deodorizing material 8 formed by accordionally folding a material obtained by mixing fiber activated carbon, granular activated carbon, or the like with a nonwoven fabric formed of another fiber material are provided.
Both end surfaces 8b of the deodorizing material 8 are adhered to the long side surface portion 5 of the casing 1 in an airtight manner, one of which is adhered to the short side surface portion 6 of the casing 1 and the other is adhered to the partition portion 4. I have.

The deodorizing section 3 is formed in a honeycomb shape from granular activated carbon or activated carbon paper, etc.
The short side surface portion 6 and the partition portion 4 are adhesively held.

In the filter constructed as described above, the carbon particles, which are fine particles, are captured by the filtering member 7 of a material such as an electrostatic non-woven fabric by the electrostatic effect on the upstream side of the filtering section 2 and flow into the vehicle interior. At the same time, it is possible to prevent dust from adhering to the deodorizing agent 8, to make the effect of the deodorizing material 8 last longer, and to assist the deodorizing of the deodorizing section 3 to enhance the deodorizing effect.

Further, since the honeycomb-shaped coarse deodorizing section 3 is provided in parallel with the filtering section 2, even if the filtering section 2 is clogged, the honeycomb-shaped deodorizing section functions as a detour, and coarse dust is removed. It can perform the functions of dust removal and deodorization, and has the effect of preventing a reduction in air flowing into the vehicle interior and a reduction in performance of the air conditioner even when the vehicle travels without replacing the clogged filter.

In the second embodiment shown in FIG. 2, the filtering section 2 of the first embodiment is composed of two layers of the filtering member 7 and the deodorizing material 8, whereas the filtering section 2 is composed of one layer. And a filter material 9 selected from a nonwoven fabric, a deodorizing filter material, an activated carbon-mixed electrostatic nonwoven material, and the like.

In the filter configured as described above, since the filtering section 2 is composed of a single layer, an inexpensive and lightweight filter can be obtained.

[0017]

As described in detail in the above embodiment, the filter for the vehicle interior according to the present invention has the filtering unit and the deodorizing unit installed in parallel, so that dust removal and deodorizing are performed simultaneously. Even if the filtering unit is clogged, the deodorizing unit is honeycomb-shaped and rough, so the honeycomb-shaped deodorizing unit works as a detour, and can perform the function of removing and deodorizing coarse dust. Even if the vehicle is driven without replacing the filter, there is an effect of preventing a reduction in air flowing into the vehicle interior and a reduction in performance of the air conditioner.
