Description

[Detailed Description of the Invention] This invention relates to a vehicle air conditioner with an improved fixing structure for an air filter.

A conventional ceiling-type vehicle air conditioner has a configuration shown in FIG.

That is, air suction ports 2, 2 provided on the lower surface of the main body 1
A blower 4 driven by a double-axis fan motor 3 from
, 4, as shown by the arrow a, the interior air drawn into the main body 1 passes through the air filters 5, 5, and the heat exchangers 6, 6 for heat exchange, and then enters the interior of the vehicle from the air blowing lower 7. The air is blown out as shown by the arrow.

Accordingly, the air filters 5, 5 are fixed to the heat exchangers 6, 6, and side support members 8, 8 are provided below the heat exchangers 6, 6 to prevent movement in the traveling direction of the vehicle. It was held by lower support parts 10, 10 provided on the front surfaces of the dew pans 9, 9 and upper support parts 12, 12 provided on a cover 11 covering the upper surface of the main body 1.

Therefore, in order to clean the air filters 5, 5, after removing the cover 11 from the main body 1,
o,i.

I had removed it from there.

After cleaning the residue, move the air filters 5, 5 to the lower support part 10.
．． However, as shown in FIG. 2, it is impossible to attach the cover 11 because the air filters 5, 5 will fall to the left around the lower support parts 10, 1o. It was a hassle for the operator to have to support the filters 5, 5.

This idea was made with attention to the above-mentioned circumstances, and by providing a holder on the side support member of the air filter installed on the front of the heat exchanger, the air filter can be prevented from falling even when the cover is removed. The object of the present invention is to provide a vehicle air conditioner in which the cover can be easily attached.

An embodiment of this invention will be described below based on the drawings.

21 in FIGS. 3 to 5 is a main body, and this main body 21
Air suction ports 22.22 are provided on the bottom surface of the main body as shown by arrows A and A from these air suction ports 22, 22 by a blower 24.24 driven by a fan motor 23 having both shafts. The air inside the car that is sucked into the air filter 21 is passed through an air filter 25.25 having a filter frame 25a.
After passing through heat exchangers 26 and 26 for heat exchange, the air is blown out into the cabin from air outlets 27 and 27 as shown by arrow B.

Therefore, the air filter 25.25 is connected to the heat exchanger 26°2.
Side support members 2B, 2B are fixed to 6 to prevent movement in the direction of travel of the vehicle, and a groove-shaped lower support part is fixed to the front surface of the dew pans 29, 290 provided below the heat exchanger 26°260. 30, 30 and the side support member 28.2B
Holder 31.3 with an L-shaped cross section provided above the
1.

A cover 33 lined with a heat insulating backing 32 is provided on the upper surface of the main body 21, and is detachably attached to the main body 21 with screws 34, 34.

Next, the operation of this invention will be explained.

To remove the air filter 25.25, first remove the cover 33.
After removing the air filter 25, hold the holder 31,
Move it upward while sliding it along the inner surface of 31.

To install the air filter 25.25 again after cleaning, etc., insert the filter frame 25a from above the L-shaped holder 31.310 provided on the side support member 28. Move the lower support part 30
．． 30.

As explained above, the side support members provided on the air filter and the heat exchanger prevent the vehicle from moving in the direction of travel, and the holder is placed on the lower support section provided below, and the holder provided on the side support member. Since the air filter is held in an upright position, the air filter will not fall over even if the cover is removed and the button is pressed, making it easier to attach the cover during cleaning.
