The air purifier shown in FIG. 6 is provided below the rear parcel 2 located behind the rear seat 1 of the vehicle, and has an air inlet 3 at one end in the vehicle width direction of the rear parcel 2 and an outlet at the other end. 4 are provided respectively. Air inside the vehicle compartment is sucked in from a suction port 3 by a fan (not shown), and purified air that has passed through a dust filter (not shown) is blown out from a blowout port 4 into the vehicle compartment.

[0003]

In such an on-vehicle air purifier, a louver is generally provided at both the suction port 3 and the air outlet 4, but the conventional louver on the air outlet 4 side is provided with a louver.
The direction is set so that the air from the air outlet 4 is blown upward or forward (the traveling direction of the vehicle), and the air blown from the air outlet 4 occupies the space where the head of the rear occupant is located as shown in the figure. The air is sucked into the suction port 3 while floating. For this reason, when the rear passengers smoke,
Smoke that could not be purified was blown out from the air outlet 4 toward the occupant's head on the right side in the figure, and the smoke was liable to fill the space on the rear seat side, sometimes deteriorating comfort.

[0004] It is an object of the present invention to provide an on-vehicle air purifier that suppresses an adverse effect on occupants due to cigarette smoke by changing an air circulation route.

[0005]

FIG. 1 shows an embodiment of the present invention.
The present invention has an air inlet 3 and an air outlet 4 behind a rear seat in a vehicle interior,
Blow-out direction setting means 6 for determining the blow-out direction of air to blow-out port 4
Applied to vehicle air purifiers equipped with The blowing direction setting means 6 is set so that the blowing air is blown toward the space between the left and right occupant occupied spaces SL and SR of the rear seat, thereby solving the above problem. Claim 2
According to the invention, the blowing direction is such that after the blown air passes through the space between the left and right occupant occupied spaces SL and SR, it is sucked from the suction port 3 through the space between the one occupant occupied space SL and the side wall of the passenger compartment. Is set. According to the third aspect of the present invention, the blowing direction is set such that the blowing air rises and proceeds in the space between the left and right occupant occupied spaces SL and SR. According to a fourth aspect of the present invention, the blowing direction setting means has a plurality of slit-shaped openings and is constituted by a louver 6 provided so as to cover the blowing port 4. According to a fifth aspect of the present invention, the suction port 3 is provided at a position substantially in contrast to the outlet 4 with respect to the center line L in the vehicle width direction of the vehicle.

[0006] In the section of the means for solving the above-mentioned problems, which explains the configuration of the present invention, the drawings of the embodiments are used to make the present invention easier to understand. However, the present invention is not limited to this.

[0007]

According to the present invention, since the air blown out from the air outlet is blown out toward the space between the occupants' occupied spaces on the left and right sides of the rear seat, the smoke of the tobacco which cannot be completely purified is removed. Discomfort can be reduced without being blown out toward the occupant. If the air passing through the space is directed to the suction port through the space between the one occupant occupied space and the cabin side wall, the air (smoke) passing through the left and right occupant occupied spaces can be reduced to a minimum. . If the direction of air blowing is set by a louver provided at the outlet, and a similar louver is provided on the inlet side symmetrically with the outlet, the appearance can be improved.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a plan view of a vehicle showing a characteristic portion of an on-vehicle air purifier according to an embodiment, and the same components as those in FIG. 6 are denoted by the same reference numerals. In the following description, “left” and “right” are directions not based on the vehicle traveling direction but based on FIG.

The air purifier is provided below the rear parcel 2 located behind the rear seat 1 of the vehicle, as in the prior art.
The rear parcel 2 is provided with an inlet 3 and an outlet 4 so as to be opposed to a center line L in the vehicle width direction. That is, the suction port 3 is located immediately after the space occupied by the left occupant's head (hereinafter, left head space) SL, and the outlet 4 is occupied by the right occupant's head (hereinafter, right head space) S
The louvers 5 and 6 are provided immediately after R, respectively, so as to cover each of them. The arrangement positions of the suction / outlets 3 and 4 and the dust collecting structure (not shown) including the fan and the filter are the same as those in the related art, but the directions of the louvers 5 and 6 are different from those in the related art.

FIG. 2 is a plan view showing the louver 6 on the outlet side, and FIG. 3 is a sectional view taken along the line III-III. Louver 6
Has a plurality of plate members forming a plurality of slit-shaped openings (air blowing openings), and the extending direction of each plate member, that is, the opening, is a direction inclined by an angle θ1 with respect to the vehicle width direction. . Further, each plate member is arranged to be inclined upward by an angle θ2 with respect to the horizontal direction. Therefore, when the fan is driven, the air from the outlet 4 is blown to the left front in the vehicle front-rear direction and obliquely upward in the horizontal direction. In other words, most of the blown air does not proceed to the right head space SR, but proceeds while rising in the space between the left and right head spaces SL and SR. As a result, even if the smoke of the tobacco, which has not been completely purified by the filter, is blown out from the air outlet 4, the smoke does not cover the right occupant. In addition, since the smoke directly discharged from the right occupant also joins the flow of the blown air and proceeds, the smoke does not stay around the right occupant.

On the other hand, the air that has proceeded in the above-mentioned direction reaches the vicinity of the ceiling at the left front of the rear seat 1, and from there, goes to the suction port 3 by the suction force of the fan. At that time, the air proceeds obliquely downward in the space between the left head space SL and the left side wall of the vehicle, and is sucked from the suction port 3. Therefore, the amount of air (smoke) passing through the left head space SL is reduced as compared with the related art.

FIGS. 4 and 5 show the louver 5 on the suction port side. The opening of the louver 5 extends in a direction opposite to the opening of the outlet-side louver 6 with respect to the center line L in the vehicle width direction, so that the appearance can be improved. Since the direction of the suction port side louver 5 does not affect the air flow path, the direction may be the same as the conventional direction if the appearance is not considered.

As described above, in the present embodiment, the angle of the louver 6 as the blowing direction setting means is changed so that the air circulation route is optimized for both the left and right occupants. May be mainly set. That is, for example, when the angle θ1 in FIG. 3 is reduced, the air is guided to the space between the left and right head spaces SL and SR in the same manner as described above. Through to the inlet 3. This may cause the left occupant to feel uncomfortable, but has little effect on the right occupant, so this configuration may be used.
