Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a filter device for a vehicle air conditioner, which is provided at the intake port of a blower unit of the vehicle air conditioner.

(Prior art) In recent years, in vehicle air conditioners, dust sucked into heat exchangers such as cooling units from blower units causes clogging of the heat exchanger fins, which deteriorates the performance of the air conditioners. In addition, there is a risk that microorganisms may propagate and generate bad odors. To prevent this, it is known that a filter device is removably attached to the suction port of a blower unit so that it can be cleaned.

(Problem that the invention aims to solve) However, the blower unit of a vehicle air conditioner generally has an outside air intake port located above the glove box of the instrument as seen from the seat, and an outside air intake port that introduces outside air. From the perspective of intake noise, the inside air intake port that introduces inside air is installed facing the front of the vehicle body, so even if a filter device is removably attached to the inside air intake port, when cleaning the filter body, etc. In some cases, it is necessary to remove the glove box, and even if the glove box is not removed, the installation and removal operations are difficult and time-consuming, and frequent cleaning is difficult.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a filter device for a vehicle air conditioner in which the filter body can be easily taken in and out for cleaning without removing the glove box.

(Means for Solving the Problems) A filter device of the present invention is a filter device provided at an air intake port of a vehicle air conditioner, and includes a filter main body disposed opposite to the air intake port;
A winding member of a predetermined length attached to one end of the filter body, a winder for winding the winding member, and a drawer attached to the other end of the filter body for pulling out the filter body from the air intake port. The structure includes a member.

(Function) When the filter body is installed, the winding member is wound up by the winder, and the filter body is arranged so as to face the air intake port.

When cleaning the filter body, by pulling the pull-out member towards the vehicle interior, the winding member is sent out from the winder and the filter body is pulled out from the air intake port, allowing the filter body to be cleaned.

After cleaning, when the pull-out member is released, the winding member is wound up by the winding device, and the filter main body is moved together with the winding member and is disposed facing the air intake port again.

(Example) An example of the present invention will be described below based on the drawings.

FIG. 1a is a side sectional view showing the installed state of the filter device of this embodiment, in which 1 is a glove box provided below the instrument panel and in front of the passenger seat, 2 is a dash board, 3 is a blower unit that takes in inside or outside air, and 4 is a filter device.

The blower unit 3 has a unit case 5.
, an outside air intake port 6 that introduces outside air from outside the vehicle, an inside air intake port 7 that introduces air inside the vehicle, and these intake ports 6.
and a motor 9 that selectively switches between internal and external air doors 8 and 7.
The inside air intake port 7 is located at the back of the glove box 1 when viewed from the seat side.
It is attached to the dart board 2 with the outside air intake port 6 facing upward and facing the front of the vehicle body. In addition, the outside air intake port 6 of the blower unit 3
communicates with the intake port 2a of the dart board 2,
In order to maintain airtightness between the outside air intake port 6 and the intake port 2a, a ring-shaped sealing material 11 made of urethane or the like is provided.
is interposed.

The filter device 4 includes a filter body 12, strings 14 and 15, and a winder 18.

The filter body 12 is flexible, has an area approximately equal to or slightly larger than the suction port 7, and includes activated carbon. In addition, a drawer cord (drawer member) having a ring 13 is provided at the lower end of the filter body 12.
14 is attached, and a winding string (winding member) 15 is attached to the upper end of the filter body 12. The other end of the winding string 15 is tied to a winding roll 19 of a winder 18, and by pulling the ring 13, it is drawn out as shown in FIG. 2, and by releasing it, it is drawn out as shown in FIG. As shown, it is wound up on a winding roll 19. Therefore, the length of the drawer of the filter body 12 is determined by the length of the winding string 15, and the length of the winding string 15 may be arbitrarily set depending on the blower unit 3 and the vehicle type.

The winder 18 includes at least a winding roll 19 for winding the winding string 15, and a spring (not shown) that constantly biases the winding roll 19 in the direction of the arrow in FIG. Blower unit 3
It is provided at the upper part of the inlet 7 of the. A guide roller 21 is provided below the suction port 7 to guide both the filter body 12 and the winding string 15, so that the filter body 12 is arranged to face the suction port 7. There is. In the figure, reference numerals 20 and 22 indicate supports that support the take-up roll 19 and the guide roller 21, respectively. Further, a locking protrusion 16 is provided protrudingly provided on the blower case 5, and as shown in FIG. 18 is regulated, and the filter body 12 is held at an appropriate position relative to the suction port 7. The above-mentioned filter body 12 can also be mounted and held by providing hooks 17 at appropriate locations on which the ring 13 can be hooked, as shown in FIG. 1a.

Further, the winder 18 is provided with a feeding and holding mechanism (not shown). As shown in FIG. 2, this drawing-out holding mechanism is configured as an automatic return type that temporarily holds the drawing-out state when the ring 13 is pulled and stopped, and releases the holding state with the next drawing operation. For example, it can be configured with a pawl and a ratchet wheel. Further, the feeding and holding mechanism can also be achieved by providing a hook or the like at an appropriate location to which the ring 13 can be hooked.

When such a filter device is installed, as shown in FIG. It is set in an appropriate position so that it can face the inside air, and dust in the inside air can be removed.

Next, at the time of cleaning, as shown in FIG.
The winding string 15 is sequentially pulled out along the guide roller 21 and the case 5 of the blower unit 3, and even if the filter body 12 is released at the maximum extended position where it is located on the vehicle floor, it is held by the extended holding mechanism. . Therefore, the filter body 12 can be cleaned by washing or the like on the floor.

Then, when the ring 13 is pulled again, the holding operation of the feeding and holding mechanism is released, and the winding string 15 is wound around the winding roll 19 until the filter body 12 is locked with the locking protrusion 16, and the filter body 12 is set at a proper position in the suction port 7.

Therefore, the filter body can be attached and detached by pulling the string, so it is easy to attach and detach without removing the glove box or blower unit as in the past, and the filter body can be cleaned frequently. It is possible to prevent a decrease in air volume due to clogging of the filter body.

In addition, the above-mentioned winding member is not limited to a string,
A flexible strip-shaped film or the like may also be used. Furthermore, the present invention can be applied even when the inside air inlet of the blower unit is not facing the dash board side, and can be applied not only to the inside air inlet but also to the outside air inlet or between each unit.

(Effects of the invention) As explained above, according to the invention, the filter body can be set by winding the winder and pulled out by hand to pull it out onto the blower. This improves the workability of attaching and detaching the filter, making it possible to clean the filter body more frequently, and reducing the frequency of decreases in air volume due to clogging.Especially for vehicles with high operating rates such as taxis, which require frequent cleaning. It can also be applied to required vehicles.
