DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air filter and a vehicle air conditioner equipped with the air filter.

[0002]

2. Description of the Related Art FIG. 2 is a longitudinal sectional view of a general vehicle air conditioner. This device is roughly divided as shown in the figure.
It is composed of a blower unit 1, a cooling unit 5, and a heater unit 9, which are combined. The blower unit 1 includes a blower 2, an inside / outside air switching damper 3, and a case 4 for accommodating them. The cooling unit 5 includes an air filter 6, an evaporator 7, and a case 8 for accommodating them. The heater unit 9 includes a heater core 10, an air mix damper 11, and a case 12 that accommodates them.

In this apparatus, the outside air or vehicle air pumped by the blower 2 enters the case 8, and after dust in the air is removed by the air filter 6, the air enters the evaporator 7.
Here, after being cooled and dehumidified, it is sent into the case 12 and divided by the air mix damper 11, a part of which is heated by passing through the heater core 10, and then mixed with the remaining air bypassing the heater core 10. As a result, the air becomes conditioned air of a predetermined temperature and is sent to the outlet.

FIGS. 3A and 3B are two views of a conventional air filter 6 used in the above-described apparatus, wherein FIG. 3A is a front view and FIG. 3B is a plan view. Reference numeral 61 denotes a filter main body made of a filtering material formed by bending a nonwoven fabric into a bell shape, 62 denotes a frame for holding the filter main body, 63 denotes a mounting flange, and the filter 6 is integrally formed. I have.

[0005] The air filter 6 is inserted into the case 8 through a mounting hole (not shown) formed in the side wall of the case 8.
The flange 63 is fastened to the side wall of the case 8 by a bolt or the like (not shown).

[0006]

The above-mentioned conventional air conditioner for a vehicle does not have a function of deodorizing an aversive odor such as body odor, tobacco odor, and mold odor felt in the interior of an automobile. For the smell, a commercially available deodorant for a vehicle or a fragrance is separately purchased and installed in a vehicle compartment. Installation of these chemicals requires a separate installation site, and these chemicals have a deodorizing effect due to natural transpiration, so the amount of transpiration is limited.
There is a world . In addition, these drugs are located near the dash panel
Therefore, there is a problem that the deodorizing effect on the evaporator 7 , which is one of the odor generation sources of the air conditioner, is small .

[0007] The present invention is intended to solve the above-mentioned disadvantages of the prior art, to effectively deodorize the interior of a vehicle without providing an installation place in the interior of a vehicle, and to enable deodorization of an evaporator. is there.

[0008]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and relates to an air filter having the following features and a vehicle air conditioner using the same. (1) In an air filter configured by holding a filter medium in a frame, at least a part of the frame is hollow, and air that evaporates gas flows through the filter.
A deodorant enclosing tank portion for enclosing a liquid deodorant that deodorizes by being mixed into the frame is integrally formed in the same frame, and an opening is provided on the side of the tank portion facing the air path, the same opening was covered with a gas permeable membrane also show. ( 2 ) A vehicle air conditioner in which the air filter according to the above (1) is installed on the inlet side of an evaporator installed in an air flow path of a cooling unit.

[0009]

According to the present invention, since the comprises the above-described configuration, evaporated in the deodorant encapsulated tank, filter-like framework of the deodorant gasified integrally forming the deodorant sealed tank is transmitted through the gas permeable film provided on a side in contact with the road, so blown is mixed with air flowing past the air filter, it can effectively perform deodorization in the room.

In a vehicle air conditioner which blows air from an air outlet through an evaporator into a vehicle cabin,
In particular, it is possible to deodorize a bad odor in a small room such as a passenger compartment, and furthermore , the above air is provided upstream of the evaporator.
The filter is installed, so the gasified deodorant smells
Odor generated from the evaporator itself , which flows through the evaporator as a source, can be eliminated.

[0011]

1 is a front view, FIG. 1B is a front view, FIG. 1B is a plan view, and FIG. 1C is a plan view of an air filter 6 according to an embodiment of the present invention. C is a sectional view, and (d) is a DD sectional view in (a). In the drawing, the structure and operation of a filter main body 61 made of a filtering material, a frame 62 for holding the filter main body, and a mounting flange 63 are almost the same as those of a conventional air filter (FIG. 3).
This embodiment is different from the conventional air filter in that
2 is that the deodorant enclosing tank 70 is integrally provided on the side opposite to the side on which the flange 63 is provided. 71 is a square cylindrical container of the deodorant filling tank 70, 72 is a deodorant replenishing port formed in the upper surface of the container, 73 is a lid attached to the replenishing port, and 74 is an air passage of the container 71. An opening formed in the side surface 71a in contact therewith, 75 is a gas permeable film made of a polyethylene film or the like covering the opening, and 76 is a liquid deodorant sealed in the container 71. The container 71 is formed of transparent plastic so that the amount of the deodorant 76 can be checked from the outside.

The air filter 6 of this embodiment is used by being attached to the above-described general vehicle air conditioner (FIG. 2). In the present embodiment, the deodorant-filled tank is installed on the opposite side of the flange of the frame, but it may be on the flange side or in the middle thereof. Further, the deodorant may include a fragrance.

In the present apparatus, the deodorant vaporized and gasified in the container 71 passes through the gas permeable film 75, flows out of the container 71, and mixes with the air flowing through the filter main body 61 to form an evaporator. The air is blown out from the air outlet into the vehicle interior through 7 to deodorize the odor in the room. By providing the deodorant-sealed tank 70 integrated with such an air filter 6, the following effects can be exhibited. (1) The gas permeable film 75 is in contact with the air passage flowing through the filter body 61 and is exposed to a wind speed of, for example, 2 to 3 m / sec. Moreover, since it is stable, a certain deodorizing effect can be obtained. (2) by placing upstream of the evaporator 7, it is possible to break the aversive odor gas odor source, it is possible to enhance the deodorizing effect. (3) No space is required for installing a deodorant in the vehicle interior.

[0014]

According to the air filter of the present invention, filtration
The air filter is constructed by holding the material in the frame
In this case, at least a part of the frame is hollow, and the evaporated gas is mixed with the air flowing through the filter.
A deodorant enclosing tank for enclosing a liquid deodorant for deodorizing by integrally forming in the same frame is provided with an opening on the side facing the air path of the tank, and the opening is provided. the so are coated with a gas-permeable membrane, without providing a location within the chamber, etc., effectively in the chamber can be deodorized.

[0015] Further, in a vehicle air conditioner in which the air filter is installed on the inlet side of an evaporator installed in an air flow path of a cooling unit, especially an air filter such as a vehicle compartment is used.
In addition to being able to deodorize bad odors in small rooms,
Install the above air filter upstream of the evaporator.
The gaseous deodorant is a source of odor
The odor which flows through the porator and is generated from the evaporator itself can also be eliminated.
