Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inside / outside air unit of a vehicle air conditioner, in which a filter member for removing dust, dust, pollen and the like in the air is incorporated in the inside / outside air blowing unit.

[0002]

2. Description of the Related Art Conventionally, as an inside / outside air blowing unit as described above, there is one described in Japanese Patent Application Laid-Open No. 9-175144. In this conventional device, a filter member is installed between the inside / outside air switching door and the blower fan in the inside / outside air blowing unit. The filter member can be removed from the inside / outside air blowing unit for replacement. Specifically, the filter member has a filter member and a rectangular frame that holds the filter member so as to surround the filter member.

[0003] The inside and outside air blower unit has an insertion hole for attaching and detaching a filter member. To take out the filter member from the inside and outside air blower unit, the frame body must be removed from the inside of the insertion hole. I draw it out of the unit. Further, in the above-described conventional apparatus, since large foreign matter (for example, leaves of a tree) that does not pass through the filter is deposited on the filtering member, the large foreign matter is caught by the opening edge of the insertion hole when the frame is pulled out, and the inside and outside air ventilation is performed. To prevent it from falling into the unit,
The front wall (rear wall) of the frame in the direction of insertion into the inside / outside air unit is higher than other portions.

[0004]

However, in the above-mentioned conventional apparatus, the height (thickness) of the frame is increased because the depth of the wall on the back side of the frame is increased, and the physical size of the inside / outside air unit is increased. There's a problem. Therefore, an object of the present invention is to prevent large foreign substances from falling into the inside / outside air blowing unit when removing the filter member without increasing the vertical dimension of the inside / outside air blowing unit.

[0005]

In order to achieve the above object, the present invention employs the following technical means. According to the first to seventh aspects of the present invention, the filter member (40) includes a filter member (41) for removing foreign matter, and the filter member (41).
And a frame member (42) that holds the filter member (40) so as to surround the filter member (40), and the filter member (41) and the inner wall (4) of the frame member (42) are provided behind the filter member (40) in the extraction direction.
2b) and a filter member (4)
Filter member (40) between 1) and inner wall (42b)
Foreign matter storage part (5) for storing foreign matter (51) when extracting
0a).

Accordingly, when the filter member is pulled out, the foreign matter moves rearward in the pulling-out direction for pulling out the filter member, and finally, the filter member and the inner wall of the frame are separated by a predetermined distance. The foreign matter is accommodated by being placed in the foreign matter accommodating portion. For this reason, when the filter member is completely pulled out of the inside / outside air blower unit, the foreign matter can be taken out of the inside / outside air blower unit without being dropped by the foreign matter storage portion into the inside / outside air blower unit. As a result, it is not necessary to increase the vertical dimension of the inside / outside air blower unit without dropping foreign matter into the inside / outside air blower unit.

According to the second aspect of the present invention, the filter member (41) has a shape bent in a wave shape, and the filter member (41) is arranged such that the traveling direction of the wave is orthogonal to the extraction direction. It is characterized by being arranged in. By the way, the present inventor tried to arrange the filtering member in a direction in which the traveling direction of the wavy wave is the same as the extracting direction of the filter member. Then, when the filter member was actually pulled out from the inside / outside air blower unit, it was confirmed that the foreign matter riding on the upper surface of the filter member scattered to the front side of the vehicle due to the elastic return of the filter member after the filter member was elastically deformed.

Accordingly, in the present invention, the filter member is hardly elastically deformed when the filter member is pulled out by disposing the filter member so that the traveling direction is orthogonal to the drawing direction of the filter member. Can be prevented. In the invention according to claim 5, the filter member (41)
A holding portion (43) for holding the filtering member (41) on the frame (42) is provided at an outer edge of the filtering member (41) at a position below the inner side of the filtering member (41). And a base part (46) that extends to the base part of the holding part (43) is provided. The holding part (43) is smaller than the height of the filtering member (41) in the air passage direction, and the foreign matter storage part is provided. (50
a, 50b) is characterized in that the holding portion (43) is used as a bottom surface and is surrounded by the holding portion (43), the inner wall (42b), and the filtering member (41).

According to the present invention, in order to form the above-mentioned foreign substance storage portion, a small filtering member is used for the frame so that a space is formed between the filtering member and the inner wall of the frame. May be. However, in this case, there is a problem that a filtration area is reduced and a passage area in the inside and outside air blowing unit is reduced. Therefore, according to the fifth aspect of the present invention, since the base portion provided on the inner edge of the frame body and serving as the base of the holding portion is provided, and the holding portion serves as the bottom surface of the foreign matter storage portion, the space of the holding portion is provided. By effectively using, the foreign matter storage portion can be configured, and the above-described problem does not occur.

In this example, the filtering member 41 is formed in a rectangular shape by foaming polyester (I-PET), and is formed to be elastically deformable. The filtering member 41 has a filtering portion 44 that is bent in a wave shape as shown in FIGS. The filtering part 44 is a part of the filtering member 41 that actually removes foreign matter in the air. The filtering section 44 is formed in a bag shape as shown in FIGS.

With the filtering member 41 mounted in the air conditioning case 2, the entire periphery of the outer edge of the lower portion of the filtering member 41
As shown in FIGS. 2 to 4, a holding portion 43 that extends inward and holds the filtering member 41 to the frame body 42 is provided. The holding section 43 is formed integrally with the filtering member 41. Specifically, the holding portion 43 is formed by crushing and solidifying the outer peripheral portion of the filtering member 41, and is sufficiently smaller (thinner) than the height of the filtering portion 44 in the air passing direction.

The frame body 42 is formed in a rectangular frame shape with a resin such as polypropylene as shown in FIG. 6 is a top view as viewed from the direction D in FIG. 2, FIG. 7 is a view as viewed from below in FIG. 6, FIG. 8 is a sectional view taken along line FF in FIG. 6, and FIG. FIG. As shown in FIGS. 2 and 6
As shown in the figure, a lattice portion 45 in a lattice shape is integrally formed at the bottom. The reason why the grid portion 45 is formed in a grid shape is to allow the air passing through the filtering portion 42 to be sucked into the blower fan 6. The lattice part 45 performs a holding function and a base function of holding the shape of the filtering member 41.

As shown in FIGS. 2 and 6, a base edge portion 4 projecting inwardly

This is a portion serving as a base of the holding section 43. Also, frame 4
An engaging portion 47 that engages with the holding portion 43 is formed integrally with 2. As shown in FIG.
The second wall portion 42a is integrally formed. The engagement portion 47 is
As shown in FIG. 8, it is formed in a triangular shape with the base on the base edge 46 side. The engaging portion 47 is formed at a predetermined interval a from the base edge portion 46 as shown in FIG. 8, and the holding portion 43 enters the predetermined interval a. Engaging part 47
6, two are formed on the front side and two on the rear side in the pulling-out direction of the frame body 42 as shown in FIG. The portion of the base edge portion 46 corresponding to the engagement portion 47 is interrupted, but this is because the die is cut off.

The wall 42 a of the frame 42 located on the rear side of the vehicle is a portion constituting the outer wall of the inside / outside air blowing unit 1, and also serves as a handle when the frame 42 is pulled out from the air conditioning case 2. Specifically, as shown in FIGS. 2 to 6, handle portions 48 are integrally formed on both sides of the wall 42 a in the vehicle width direction. As shown in FIG. 9, the handle portion 48 has a structure like a clothespin, and has a pair of handles 48a formed on the rear side of the vehicle, and a pair of clip portions 48b formed on the front side of the vehicle. Have been. On the outer wall of the air-conditioning case 2, as shown in FIG. 2, a sandwiching receiving portion 49 sandwiched between the sandwiching portions 48 b is integrally formed.

Next, a method for assembling the filter member 41 to the frame 42 will be described. First, in FIG.
1 is placed on the frame body 42 and pushed downward from above. That is, since the surrounding area and the shape of the frame 42 are substantially the same as those of the filtering member 41, the filtering material 41 is
Get inside 2. However, since the above-described triangular engaging portion 47 is provided in the frame 42, the filtering member 41 does not naturally enter the frame 42 due to the engaging portion 47.

Then, the filter member 41 is pushed downward.
Then, the pushing of the filtering member 41 is smoothly pushed by the inclined surface of the engaging portion 42, and when the filtering member 41 is pushed to the end,
When the holding portion 43 of the filtering member 41 is deformed, the engaging portion 4
Go under 2 As a result, the holding portion 43 is arranged with the base edge 46 as a base, is prevented from falling off, and the filtering member 41 is attached to the frame 42. This state is shown in FIG.
0 is shown. As shown in FIG. 10, the filtering member 41 is arranged such that the traveling direction of the wavy wave is orthogonal to the direction in which the frame 42 is extracted.

In this embodiment, the filter member 4
When 1 is attached to the frame 42, a foreign substance storage portion 50a for storing a relatively large foreign substance when the filter member 40 is extracted is formed between the inner wall of the wall portion 42 and the filter member 41. Hereinafter, the foreign substance storage unit 50 will be described with reference to FIG.
This will be described with reference to FIG. FIG. 11 is a sectional view taken along line HH in FIG. In the foreign matter storage portion 50a, the filter member 41 and the inner wall 42b (the surface on the opposite side to the 42a) of the frame member 42 are spaced apart from each other by a predetermined distance in the entire rear side of the frame member 42 in the extraction direction in which the filter member 40 is extracted. It is formed by being arranged. Specifically, as shown in FIG. 10, the foreign substance storage unit 50 a is configured to be surrounded by the holding unit 43, the inner wall 42 b, and the filtering member 41 (the filtering unit 44), with the holding unit 43 serving as a bottom surface. .

Further, such a foreign substance storage portion 50a is also provided in the whole area on the front side in the extracting direction, as shown in FIG.
As shown in FIG. 0, a foreign substance storage portion 50b is formed. Further, in the present example, such a foreign substance storage portion 50a is entirely provided between the entire inner wall of the frame body 42 and the filtering member 41, and as shown in FIG.
The foreign matter storage section in the middle and left and right directions is assumed to be 50c. Next, a method of attaching / detaching the filter member 40 to / from the inside / outside air blowing unit 1 after the filter member 41 is attached to the frame 42 will be described. Next, the function of the foreign object storage units 50a to 50c will be described.

First, when the filter member 40 is mounted in the inside / outside air blowing unit 1, the filter member 40 is inserted through the opening 30 as shown by an arrow in FIG. When the pinch engagement portion 49 is positioned between the pinions 48b and the frame body 42 is further pushed in, the pair of pinch portions 48b are elastically deformed and opened by the pushing force. Thereafter, when the frame body 42 is further pushed in, the holding portion 48b
Is elastically restored, and the holding portion 48b is engaged with the holding portion 49 so as to be hooked. Thereby, the filter member 4
0 is mounted in the inside / outside air blowing unit 1 and
And the pinch receiving portion 49.

Although not shown in the present embodiment, actually, two rows of inclined portions for guiding the insertion of the filter member 40 are formed in the inside / outside air blowing unit 1. Then, when the filter member 40 is inserted into the inside / outside air blowing unit 1 from the opening 30, the insertion tip side of the filter member 40 moves upward by the inclined surface,
The filter member 40 is inserted in an inclined state in which the insertion tip side is located higher than the rear side. Then, when inserted in this manner, the inner air / air blowing unit 1 eventually comes into contact with the inner wall on the vehicle front side. Thereby, the filter member 40
On the front side of the vehicle, the vertical position is determined,
In accordance with this, the pinch portion 48a is slightly lifted up, and then fitted into the pinch receiving portion 49.

As described above, the filter member 40 is mounted in the inside / outside air blowing unit 1 and is in the mounting state shown in FIG. Then, inside air or outside air from above passes through the filter member 40.
The leaf 51 shown in the middle is included, and the leaf is deposited above the filter member 40 without passing through the filter member 40 (the filtration unit 44).

Then, without knowing such a state, the user replaces the filter member 41 with the filter member 4.
No. 0 is pulled out of the air conditioning case 2 by pulling out the passenger seat side in a substantially horizontal direction behind the vehicle. Specifically, the pair of handles 48a are pushed so as to approach each other. This allows
The pair of clip portions 48b are opened, the engagement between the clip portions 48a and the clip receiving portions 48b is released, and in this state, the frame 42 is pulled out toward the vehicle rear side.

Then, contrary to the above-described case, the filter member 40 is in an inclined state in which the insertion tip side of the filter member 40 moves upward due to the inclined surface, and the filter member 40 is located at a position where the insertion tip side is higher than the lower side. Become. As a result, the distance between the upper edge 30a of the opening 30 and the upper surface of the filter member 41 is increased, and foreign matter deposited on the upper surface of the filter member 40 is less likely to interfere with the upper edge. It is difficult to fall into one.

When the filter member 40 is pulled out, the leaf 51, which is a large foreign material as described above, interferes with the leaf edge 51 and the opening edge 30a. 51 moves to the front side of the vehicle. Then, the leaf 51 that has moved finally enters the foreign substance storage part 50a and is stored. For this reason, when the filter member 40 is completely pulled out from the inside / outside air blower unit 1, the leaves 5
1 can be taken out of the inside / outside air blowing unit 1 without dropping it inside the inside / outside air blowing unit 1.

As described above, according to the present invention, unlike the above-described conventional apparatus, one side of the frame body 42 is not raised, and large foreign matters are not reliably dropped into the inside / outside air blowing unit 1. It is not necessary to increase the vertical dimension of the. Also,
In this example, as described above, the filtering member 41 is arranged such that the traveling direction of the wavy wave is orthogonal to the direction in which the filter member 40 is extracted. This has the following effects. The present inventor has arranged the filtering member 41 in a direction in which the traveling direction of the wavy wave is the same as the direction in which the filter member 40 is extracted. Then, when the filter member 40 is actually pulled out from the inside / outside air blowing unit 1 and viewed, the leaves 51 are sandwiched between the opening edges 30a. If the filter member 40 is further pulled out with the foreign matter clogged in this way, for example, the filtering part 44 elastically deforms in the wave traveling direction and then returns elastically, so that other foreign matter riding on the upper surface of the filtering part 44 is removed. It was confirmed that it scattered in front of the vehicle. For this reason, in this example, when the filter member 40 is pulled out, in order to make it difficult for the wavy filtering part 44 to be elastically deformed, the traveling direction is arranged so as to be orthogonal to the drawing direction of the filter member 40. Thereby, scattering of foreign matter can be prevented.

Further, according to the present invention, the foreign object storage portion 50a
In order to form ５０50c, a space may be formed between the filter member 41 and the inner wall of the frame body 42 by using a smaller filter member 41 for the frame body 42. But,
In this case, there is a problem that the filtration area is reduced and the passage area in the inside / outside air blowing unit 1 is reduced. Therefore, in this example, a base portion provided on the inner edge of the frame body and serving as a base of the holding portion is provided.
Are the bottom surfaces of the foreign substance storage units 50a to 50c,
By effectively utilizing the space of the holding portion 43 necessary for holding the frame in the frame body 42, the foreign matter storage portions 50a to 50c can be configured, and the above-described problem does not occur.

Further, in this embodiment, since the foreign substance storage section 50b is formed at a place different from the foreign substance storage section 50a, the storage space for storing a larger foreign substance can be increased, and the foreign substance is not dropped into the inside / outside air blower unit 1. Only Further, in this example, a foreign matter storage part 50c is further formed, and the foreign matter storage part is entirely provided between the entire inner wall of the frame 42 and the filtration part 44. It does not need to be dropped.

(Modification) In the above-described embodiment, the foreign substance storage section is formed on the entire inner wall of the frame 42. However, at least the foreign substance storage section 50a is sufficient. In each of the above embodiments, the position where the filter member 40 is pulled out is determined by the glow box 20.
, But may be pulled out from any position. Further, it may be pulled out in the vehicle width direction.

A packing made of urethane foam or the like is attached to the outer peripheral portion of the filtering member 41, and the packing is compressed to hold the filtering member 41 in the frame 42. By setting the thickness to be smaller than the thickness of 41, the foreign substance storage units 50a to 50c may be formed.
