Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to an air conditioning deodorizing device that deodorizes air blown by an air conditioner.

(Prior Art) For example, in an automobile air conditioner, air mixed with a strange odor may be blown into the interior of the vehicle, especially when cooling operation is started.

Therefore, in order to deodorize the blown air, for example, as shown in Japanese Utility Model Application No. 61-91417,
There is an air conditioner deodorizing device that has a deodorizing filter installed in the middle of the ventilation duct. In this air conditioner deodorizing device, the deodorizing filter is formed into a flat plate shape and is installed at right angles to the air passage of the duct so as to cover the entire air passage.

(Problems to be solved by the invention) In the conventional air conditioner deodorizing device as described above, a flat plate-shaped deodorizing filter was installed to cover the entire air duct at right angles to the air duct. The airflow resistance of the deodorizing filter was large, and the air flow was significantly reduced. Moreover, if the deodorizing filter becomes clogged, there is a problem in that the ventilation resistance becomes extremely large, making it impossible to blow air.

The present invention was devised in view of the above-mentioned problems, and it is an object of the present invention to provide an air conditioner deodorizing device that can reduce airflow resistance to a small extent, and can reliably deodorize even when the airflow resistance is reduced. The purpose is to

[Structure of the idea]

(Means for Solving the Problems) The air conditioner deodorizing device of the present invention includes a case 9 having air permeability in which a plurality of spherical fibrous activated carbon materials 8 are movably housed in the air duct 5. , the upstream side of the case 9 of the blower duct 5 is connected to the lower surface side of the case 9, and a part of the air flowing inside the blower duct 5 is guided to the lower surface of the case 9, thereby causing the fibrous activated carbon material 8 to fly up. A branch duct 20 is provided.

(Function) In the present invention, the air flowing inside the air duct 5 is divided into two types: one that passes through the air duct 5 and flows to the side of the case 9, and the other that flows through the branch duct 20 and flows to the bottom surface of the case 9. The air flowing in the air duct 5 acts to press each fibrous activated carbon material 8 to the downstream side as it passes through the case 9, and the air flowing in the branch duct 20 acts to press each fibrous activated carbon material 8 to the downstream side. For example, air is sent from the lower side of the case 9 to cause each fibrous activated carbon material 8 to fly up. Therefore, case 9 when blowing air
Each of the fibrous activated carbon materials 8 moves actively within the case 9 and efficiently adsorbs odor molecules contained in the air on its entire surface to deodorize the air.

(Embodiment) Hereinafter, the configuration of an embodiment of the present invention will be described with reference to the drawings.

In FIG. 6, reference numeral 1 denotes an instrument panel of an automobile, and this instrument panel 1 is provided with a ventilator 4, the back surface of which communicates with an air outlet 3 of a duct device 2 shown in FIG.

As shown in FIGS. 1 to 3, the duct device 2 communicates a blower duct 5 provided along the lateral direction of the instrument panel 1, and a tip of the blower duct 5 with the ventilator 4. The air duct 5 is provided with a curved air duct 6.
is connected to a blower unit (not shown) provided in the center of the instrument panel 1,
Then, the air from this air blowing unit is blown out from the ventilator 4 through the ducts 5 and 6.

A rectangular opening 7 is provided on the upper surface of the air duct 5, and a breathable case 9 containing a spherical fibrous activated carbon material 8 is disposed within the air duct 5 through this opening 7. . In this case 9, a ventilating net 11 is stretched around the circumferential side and bottom of a rectangular case frame 10, and a mounting piece 12 on the upper edge of the case frame 10 is attached to the edge of the opening 7 of the duct 5. attached by a fixing member 13;
In addition, inside this case 9, two partitions 15 with a net 14 stretched thereon to allow ventilation are fitted with mounting bosses 16 protruding from the edges into mounting holes 17 on the case 9 side, so that the downstream side of the air blower is fitted. Each of the partitions 15 is mounted in an upwardly tilted position, and a plurality of the spherical fibrous activated carbon materials 8 are movably housed in the upper and lower portions of each partition 15.

At the bottom of the air duct 5, there is an inlet 1 at one end.
8 communicates with the throttle part 5a of the air duct 5 on the upstream side of the arrangement position of the case 9, and the air outlet 19 at the other end communicates with the lower surface side of the case 9 of the air duct 5, so that the branch duct 20 is formed. It is provided.

Further, the instrument panel 1 has a fourth
As shown in the figure, an elastic body 22 such as urethane and a skin body 23 are integrally provided on the surface of an iron plate 21, and an opening 24 that opens above the opening 7 of the air duct 5 is provided. A lid 25 is attached to the opening 24 with a hinge (not shown) so that it can be opened and closed. A ventilation duct 5 is provided on the bottom surface of this lid body 25.
A urethane seal 26 is provided to seal the opening 7, that is, the upper surface of the case 9, and a magnet 27 is provided which is bonded to the iron plate 21 to maintain the closed state of the lid 25.

The air sent from the air blower unit into the air duct 5 is divided into two types: one that passes through the air duct 5 and flows to the side of the case 9, and the other that flows through the branch duct 20 and flows to the bottom surface of the case 9. According to the air flowing in the air duct 5, each fibrous activated carbon material 8 is released as it passes through the case 9.
According to the air flowing in the branch duct 20, the case 9
Wind is sent from the lower side of the fibrous activated carbon material 8 to cause each fibrous activated carbon material 8 to fly up. Therefore, each fibrous activated carbon material 8 in the case 9 when blowing air
move around actively inside the case 9 and efficiently adsorb odor molecules contained in the air on its entire surface to deodorize it.

Note that if only the air flowing through the air duct 20 acts, the fibrous activated carbon material 8 will be pressed to the downstream side of the case 9 and block the air passage, but the air flowing through the branch duct 20 will cause each fibrous activated carbon material 8 to In order to prevent the activated carbon material 8 from flying up and blocking the ventilation path, the ventilation resistance of the air passing through the case 9 is small, and the decrease in the airflow is small.

The fibrous activated carbon material 8 also has the function of removing dust contained in the air from adhering to the surface thereof.

The deodorized air that has passed through the case 9 then passes through the air ducts 5 and 6 to the ventilator 4.
It is blown out from.

In addition, when replacing the fibrous activated carbon material 8, open the lid 25 of the instrument panel 1, remove the two partitions 15 from the case 9 as shown in FIG. The fibrous activated carbon material 8a is removed and a new fibrous activated carbon material 8 is prepared.
