Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a filter mounting structure for an automotive air conditioner installed in an instrument panel.
[0002]
[Prior art]
Conventionally, as shown in FIG. 5, there is an instrument panel 1 provided with an automotive air conditioner. This conventional example will be described below. A blower unit 4 is installed in the instrument panel 1 via a blower case 5, and an insertion portion 8 of a filter 140 is formed in the ventilation path of the blower case 5, and the filter 140 is inserted in the insertion portion 8. It is detachably inserted.
[0003]
Below the insertion portion 8 of the filter 140, there is formed a space portion 7 which is a ventilation path between the inside air A circulating in the room and the outside air B sucked from the outside air intake of the body 3, and this space portion is exposed. 7, a damper 6 for switching between the inside air A and the outside air B is provided. Further, the lower cover 2 disposed in front of the passenger seat at the part of the filter 140 that is detachably inserted into the insertion portion 8 is detachably attached to the instrument panel 1 by a stopper such as a clip or a bolt. [0004]
[Problems to be solved by the invention]
The filter 140 needs to be cleaned or replaced in order to ensure its dust removal function. Therefore, in order to remove the filter 140 from the insertion part 8 and insert it again into the insertion part 8, the lower cover 2 must be removed in the above-described conventional structure, which requires removal of clips, bolts and other fasteners. Further, in order to remove the lower cover 2, it is necessary to remove other parts of the instrument panel 1, and there is a problem that it takes many man-hours for removing and attaching these parts.
[0005]
An object of the present invention is to provide a filter mounting structure for an automotive air conditioner in which an air conditioner filter installed in an instrument panel can be easily attached and detached from the room without removing a lower cover. .
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is characterized in that, as described in claim 1, a recess is formed in a lower cover disposed in front of a passenger seat of an instrument panel in which an air conditioner is installed. A hole is provided in the inner wall surface of the recess, and a filter disposed in a ventilation path in the blower case of the air conditioner is detachably inserted into the hole, and a lower cover is located in the recess at one end of the filter. And a handle constituting a continuous surface is provided .
[0007]
According to a second aspect of the present invention, the length of the lower cover disposed in front of the passenger seat of the instrument panel in which the air conditioner is installed is shortened, and the ventilation path in the blower case of the air conditioner is provided. An end of the filter that is detachably inserted is provided with a handle that extends the lower end of the portion of the lower cover that is continuously shortened and extends the lower cover, and that forms a surface that is continuous with the lower cover. It is characterized by.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[Example 1]
FIG. 1 shows a first embodiment of the present invention. In FIG. 1, 1 is an instrument panel, and 2 is a lower cover disposed in front of the passenger seat of the instrument panel 1. An air conditioner is disposed in the instrument panel 1 surrounded by the lower cover 2. That is, the blower unit 4 is installed via the blower case 5, and an insertion portion 8 for a filter 14 described later is formed in the ventilation path of the blower case 5. Below the insertion portion 8 of the filter 14, a space portion 7 is formed to join the inside air A circulating in the room and the outside air B sucked from the outside air intake of the body 3. A damper 6 for switching between the inside air A and the outside air B is provided.
[0009]
In the first embodiment of the present invention, in the above configuration, the recess 9 is formed in the lower cover 2 disposed in front of the passenger seat of the instrument panel 1, a hole is provided in the back wall surface of the recess 9, and the blower case 5 is formed. An extension part 14a extending to the lower cover 2 is formed in the filter 14 that is detachably inserted into the inserted insertion part 8, and is inserted into the hole, and is positioned in the recess 9 at one end of the extension part 14a. A handle 15 is provided.
[0010]
As means for removably guiding the filter 14, the guide 10 attached to the lower cover 2 with a reinforcing rib 11 in the hole on the back wall surface of the recess 9 formed in the lower cover 2, and the insertion into the blower case 5 The guide 12 and the guide rib 21 that are continuous with the portion 8 are provided. The guides 10 and 12 and the guide rib 21 may be either the lower cover 2 side or the blower case 5 side. Reference numeral 13 denotes a seal provided on the extension 14a.
[0011]
Moreover, you may utilize the equipment currently installed in the instrument panel 1 as a means to guide the filter 14 so that attachment or detachment is possible. For example, as shown in FIG. 2, when the washer tanks 16a and 16b are installed in the instrument panel 1, the space between the washer tanks 16a and 16b can be used as a guide.
[0012]
[Example 2]
FIG. 3 shows a second embodiment of the present invention. The basic structure of the second embodiment is the same as that of the first embodiment. In the case of the second embodiment, the length of the lower cover 2 disposed in front of the passenger seat of the instrument panel 1 is shortened, and the lower end of the lower cover 2 is connected to the extension 14a of the filter 14 continuously with the lower end of the lower cover 2. A handle 17 is provided to supplement the extension, and a stopper such as a clip 18 is attached to the handle 17 so that the handle 17 is fixed in a hole provided in the lower end portion of the lower cover 2.
[0013]
The handle 17 provided on the extension 14a of the filter 14 is formed integrally with the extension 14a, or as shown in FIG. 4, the handle 17a is a separate part from the extension 14a. The extension 14a may be connected by male and female connecting members 19 and 20.
[0014]
In any of the first and second embodiments of the present invention, the filter 14 can be pulled out and inserted / removed by the handles 15, 17, 17 a, so that the working environment is good without removing the lower cover 2 as in the prior art. The filter 14 can be easily detached from the room, and the serviceability such as cleaning and replacement of the filter 14 is improved.
[0015]
In the case of the structure of the second embodiment, a design surface that extends and supplements the lower end of the lower cover 2 shortened by the handles 17 and 17a is formed, and by pulling out the filter 14, the lower space of the lower cover 2 is opened. A large working space can be secured for maintenance, inspection work, etc. in 1 to improve workability.
[0016]
In addition, when the handle 17a is a separate part from the extension portion 14a shown in FIG. 4, the filter 14 itself is downsized to reduce the cost.
[0017]
【The invention's effect】
As described above, according to the present invention, the filter of the automotive air conditioner installed in the instrument panel can be detached from the room without removing the lower cover of the instrument panel. Improve workability. Further, in the structure of claim 2, in addition to the above effects, the lower space of the lower cover is opened by pulling out the filter, and a large work space can be secured for maintenance and inspection work in the instrument panel, so that workability is good. Can be.
