Description

DETAILED DESCRIPTION OF THE INVENTION (Object of the Invention) The present invention relates to an improvement of an outside air introduction structure incorporated for introducing outside air into a passenger car room, and particularly to an improvement in outside air such as recent road dust and pollen. In order to enable comfortable driving without adversely affecting the human body of drivers and passengers due to the increased amount of dust, etc., it is intended to provide a new method of purifying outside air that has never been introduced before. is there.

(Prior art) Passenger cars have been a necessity of daily life for a long time, and the time for driving a car for commuting, for work, or for home life, or for staying in a passenger car as a passenger, becomes extremely long. Notice that it is coming.

These phenomena include the fact that the economic situation has stabilized and everyone has been enriched, and the price of passenger cars themselves has been relatively stable for a long period of time, making them easier to purchase,
Furthermore, road conditions have been improved, and safe driving and movement are now possible everywhere. This is expected to be due to the fact that the number of passenger cars owned has increased significantly.

Under these circumstances, the quality of passenger cars has been further improved due to the development of new materials and the development of electronics technology, etc., and the performance of vehicles, operability, safety, durability, etc. Advances and developments have been made, and extremely high-performance passenger cars capable of driving even women who are said to be vulnerable to the mechanism without any difficulty are being developed and marketed one after another.

However, on the other hand, the number of passenger cars has increased too much, and it has continued to suffer from exhaust gas pollution and noise pollution, and each time it has been overtaken by measures such as new regulations and installation of new facilities such as exhaust gas regulations and installation of soundproof walls. Was. The recent pollution problem due to road dust has also become a major social problem, and movements to solve this problem have become very active due to regulations on spike tire equipment and production regulations. Is in a situation.

Looking at countermeasures against this dust pollution, most of them focus on the parts that generate dust, that is, regulations related to tires, and it is possible to develop tires that guarantee safe driving even on snowy roads There is a view that it is all over the response to what to do or what to do with the pavement material of the road, and it is natural that they are basic problems and there is no difference in the problems that need to be solved, It is not easy to say that the problem is as simple as possible, and therefore, considering how to deal with it until it is solved should be a very important issue at present. As it is, progress so far,
In the ever-evolving structure of passenger cars, no proposal on this point has been made.

In view of such circumstances, the present invention places importance on the health problems of modern people, who are increasingly staying in the passenger compartment more and more, and at present, develops and researches at least to improve the environment in the passenger compartment. As a result, we noticed a defect in the structure of introducing outside air into the passenger compartment, which had been completely unchecked, and succeeded in developing and realizing an extremely innovative method of purifying outside air as detailed below. Things.

(Structure of the Invention) As can be clearly understood from the representative embodiment shown in the drawings, the method for purifying introduced outside air of a passenger car according to the present invention is already provided at a suitable position outside the passenger compartment as a passenger car ventilation system. A frame of a filter member having a shape larger than the outside air intake is detached and attached to the outside of the existing outside air intake formed so as to protrude from the substrate so as to fit around the existing outside air intake. Free air outlets and other benches that can be opened inside the car by being retrofitted and mounted freely without changing the structure related to the ventilation system already installed in passenger cars, such as existing ventilation boxes and fresh air ducts That the dust content in the outside air introduced from the It is a method for purifying outside air introduced into a passenger car.

Conventional ventilation boxes are not always formed at the same location depending on the type of passenger car and manufacturer, but most of them are located under the front window at the border with the hood (some models have a front hood). This is a space that communicates with the outside air intake provided outside the vehicle, such as an air scoop grill, ventilator, and inlet vent provided on the fender or headlight garnish. It is isolated from the engine room and the room by a dashboard, partition, etc. This is a part that takes in outside air together with rainwater and dust from a grid-like member such as an air scoop grill, a ventilator, and an inlet vent.

Then, a part of the dashboard or the partition wall facing the ventilation box is hollowed out, and one end thereof is connected to the fresh air outlet formed in the instrument panel in the passenger compartment in the hollowed out portion. An inner duct (also referred to as a fresh air duct) is fitted, and the outside air inlet, which is the other end, is usually provided in the above-mentioned ventilation box without being protruded or formed in a protruding shape and with the inlet being open. Although it is possible to prevent rainwater from entering, the outside air containing dust is guided as it is, and some special structure has been adopted so far to remove dust at this outside air intake. What was done was not considered at all.

The filter member has a frame large enough to fit on the outer periphery of the outside air intake, and has a structure in which a filter is housed inside.The filter member protrudes from the vehicle body partition at the outside air intake of the inner duct described above. The crown is detachably attached and mounted so as to be fitted to the outer periphery of the portion having the shape.

The structure of the filter member is not particularly limited as long as it is formed in an optimal structure that can be fitted to the outer periphery of the protruding outside air introduction port. A part is connected to the car body partition with a hinge, and it is rotated by the hinge part, and only the filter is detached and replaced. What you get,
The portion corresponding to the frame of the filter member is formed as being attached to the vehicle body partition wall or directly fitted into the outer wall surface of the projecting outside air intake, and corresponds to the frame. Any structure can be adopted as long as the filter can be substantially replaced, such as a filter that can be detached in a sliding manner from a slit provided in an easy-to-operate portion.

In addition, if necessary, a bypass structure is arranged in a part of the filter member so that the intake of outside air through the filter and the intake of outside air as before without passing through the filter can be freely selected by remote control. It is also possible to adopt a structure with a switching damper.

Filters are filter materials of all properties that have already been adopted as other devices and parts, such as non-woven fabrics, woven fabrics, special papers, sponges, etc., as well as filter structures that combine them or use static electricity alone Of course, it is also possible to adopt.

In the present invention, the technical idea of directly attaching and detaching a filter member directly and detachably to an existing outer air intake outer surface is detachably attached to a conventional passenger car already used for use (of course, the outside air intake outside). It is not limited to the case where the filter member is directly attached and detached on the side so that it can be detached and attached afterwards, but it is not limited to that, and the structure related to the ventilation system is manufactured with the same structure as before It goes without saying that some new passenger cars are naturally included in the case of adopting them at the factory production stage or the shipping stage.

Hereinafter, specific examples shown in the drawings will be described.

(Embodiment 1) The embodiment shown in the drawings merely shows one embodiment of the simplest structure of the present invention, and is, for example, an inner duct used in Volkswagen Golf (model name). 3 as in the outside air intake
Inner duct 3 with outside air intake projecting from
The filter member 2 is provided inside the peripheral frame formed to be larger than the outside air inlet outside shape.
The filter member 2 for dust removal, which is finely bent to increase the surface area, is integrally incorporated. The filter member 2 is formed around the inlet of the outside air intake projecting from the ventilation box. In order to reduce or eliminate the dust content in the fresh air outlet and other ventilation introduced from the ventilation, which is directly and detachably attached to and fitted to the body, This is an example of a passenger car that adopts a method for purifying introduced outside air.

In this embodiment, as for the switching damper portion, the illustrated filter member 2 itself is opened and closed (not shown) with respect to the outside air inlet 3 by remote control.

FIG. 1 shows a plan view of a filter member 2 employed in this method for purifying introduced outside air, and FIG. 2 shows a longitudinal sectional view at the center. FIG. 3 is a partial perspective view of the outside air intake 3 of the inner duct for illustrating this structure.

(Function and Effect) The method for purifying the outside air introduced into a passenger car according to the present invention having the above-described configuration is an inter-duct which has never been omitted, and the outside air inlet 3 projecting from the vehicle body partition 4. With the extremely simple structure in which the filter member 2 for dust removal, which can be directly detached and attached, can be directly attached to and detached from the outside surface of the vehicle, without changing the structure of the existing ventilation box and fresh air duct, The present invention has realized a novel method of purifying outside air which does not contain but reduce substances harmful to the human body such as dust and pollen in the outside air taken into the apparatus.

In particular, the structure as shown in the embodiment is the simplest structure, can be provided at a low cost, is easy to handle for replacement, and is above all the existing inner duct 3 and its surroundings. On the other hand, it has an excellent feature that the structure of the present invention can be realized without requiring any modification.

In this way, it is directly attached to the outside surface of the outside air intake, which has been a blind spot until now, that is, the introduced outside air for all passenger cars without changing the structure of the existing ventilation box and fresh air duct. This invention, based on the extremely simple knowledge that it is possible to realize a purification method, does not enforce thorough spike tire control, and roads in the Tohoku region suffer from road dust shaved by them, and volcanic ash such as Kagoshima city etc. Drivers who drive for long periods of time on polluted roads, such as autumn or early spring or in the early spring, or those who are riding in these cars, are unknowingly harmed by the outside air taken into the car without their knowledge. It is possible to prevent the situation that cannot be overlooked such as If not cause, it is expected from the fact that it is also surely dispel the discomfort caused by dust or the like which occurs during normal operation, as those high reputation as an extremely useful invention for modern people can not escape from the car society is made.
