(Structure of Chamber of air conditioner for vehicle, etc.)
The configuration of the cavity C and the like provided in the vehicle air conditioner 1 according to the present embodiment will be described with reference to fig. 3 to 6.
Here, fig. 3 is a sectional perspective view showing a cavity C and the like provided in the vehicle air conditioner 1 according to the embodiment; fig. 4 is a sectional view showing a ventilation state of the air conditioner 1 for a vehicle; FIG. 5 is a top sectional view thereof; fig. 6 is a schematic plan view showing the overall configuration of the air conditioner 1 for a vehicle.
As shown in fig. 3, the air conditioner 1 for a vehicle is provided with, on the front side (the riding compartment side of the vehicle): front-seat foot openings FF1, FF2 formed on both side surfaces of the air-conditioning box 4, and rear-seat foot openings RF1, RF2 formed between the two front-seat foot openings FF1, FF 2. Further, the air conditioner 1 for a vehicle is provided with: front-seat leg ducts 500A and 500B each including front-seat leg ducts 501A and 501B communicating with the front-seat leg openings FF1 and FF2, and a rear-seat leg duct 700 (see fig. 4) including a rear-seat leg duct 701 communicating with the rear-seat leg openings RF1 and RF 2.
The air conditioning box 4 is formed with a cavity C communicating with the front-seat foot ducts 500A and 500B and the rear-seat foot duct 700.
The cavity C has: a first region a1 communicating with each of the front-seat foot paths 500A, 500B; and second regions A2a and A2b which are disposed adjacent to the left and right of the first region a1 and communicate with the first region a 1.
The cavity C further includes rear-seat auxiliary ducts 600a and 600b, and the rear-seat auxiliary ducts 600a and 600b communicate with the rear-seat foot duct 700 on the downstream side of the first region a1 and on the downstream side of the second regions A2a and A2b, respectively.
in the configuration example of the cavity C shown in fig. 3, the first region a1 is formed by the narrowest portion 800 that extends in the vehicle width direction in the cavity C and that narrows the passage diameter of the air-conditioning wind in the cavity C.
The second regions A2a and A2b are formed of large diameter portions 801a and 801b having a larger diameter than the narrowest portion 800.
The front-seat leg openings FF1 and FF2 open in the vehicle width direction.
In the air conditioning device 1 for a vehicle of the present embodiment, the cavity C that communicates with the front-seat foot tunnel 500A, 500B and the rear-seat foot tunnel 700 has the rear-seat auxiliary tunnels 600A, 600B that communicate with the rear-seat foot tunnel 700 on the downstream side of the first region a1 and on the downstream side of the second regions A2a, A2B, respectively. Accordingly, the cross section of the foot duct 700 for the rear seat can be sufficiently obtained without increasing the size of the vehicle in the front-rear direction, and a sufficient air volume can be secured for the rear seat.
here, the ventilation state of the cavity C and the like of the vehicle air conditioner 1 will be described with reference to fig. 4 to 6.
As shown in fig. 4 to 6, the air-conditioning winds W50A, W50B flow into the front-seat foot ducts 500A, 500B from the left and right sides of the cavity C, become air-conditioning winds W100A, W100B supplied to the side-ventilation air outlets 203, 204 shown in fig. 1, the front-seat foot air outlet not shown, and the like, and are output to the feet of the front-seat passenger.
On the other hand, the rear seat foot tunnel 700 is configured such that the air-conditioning winds W51a and W51b flow into the rear seat foot openings RF1 and RF2, and portions of the air-conditioning winds W50a and W50b flow into the rear seat auxiliary tunnels 600a and 600b as the air-conditioning winds W52a and W52 b.
In fig. 4, the portions indicated by reference numerals 510a and 510b are wall portions that protrude inward in the vehicle width direction from the upper end side of the rear seat leg duct 701 and have inner end portions that are formed so as to be spaced apart from the cavity C and into which the air-conditioning flows W52a and W52b can flow.
As shown in fig. 4 and 6, the air-conditioning winds W51a, W51B, W52A, W52B are introduced to the rear seat side via ducts 702A, 702B provided to extend toward the rear of the vehicle, and are output from the rear seat leg air outlets to the legs of the rear seat passenger as the air-conditioning winds 101a, 101B.
Here, referring to fig. 7 and 8, a ventilation state in a cavity C' or the like of a conventional vehicle air conditioner 900 will be briefly described.
Note that the same components as those of the present embodiment shown in fig. 4 and 5 are given the same reference numerals, and redundant description is omitted.
In the cavity C ' of the conventional air conditioner 900 for a vehicle, wall portions 901a and 901b extending from the rear seat leg duct 701 and coming into contact with the cavity C ' are formed below the left and right end portions of the cavity C '.
therefore, the air-conditioning winds W50A, W50B and the air-conditioning winds W200A, W200B flowing along the wall portions 901a, 901B flow into the front-seat foot ducts 500A, 500B from the left and right of the cavity C', become air-conditioning winds W100A, W100B supplied to the side ventilation air outlets 203, 204 shown in fig. 1, the front-seat foot air outlet not shown, and the like, and are output to the feet of the front-seat passenger.
on the other hand, since the rear seat foot duct 700 is configured to flow only the conditioned air W51a, W51b from the rear seat foot opening portion, the volume of air output from the rear seat foot air outlet as the conditioned air 201a, 201b to the feet of the rear seat passenger is smaller than that of the vehicle air conditioning device 1 of the present embodiment.
Therefore, in the conventional air conditioner 900 for a vehicle, if the air volume for the rear seat is to be sufficiently obtained with the same width, there are disadvantages as follows: that is, it is necessary to increase the size of the cavity C' in the vehicle front-rear direction, which makes the vehicle front-rear direction size of the entire apparatus large and cannot meet the demand for miniaturization.
In contrast, according to the air conditioning device 1 for a vehicle of the present embodiment, since part of the air conditioning flows W50a, W50b flows in as the air conditioning flows W52a, W52b through the rear seat auxiliary ducts 600a, 600b, a sufficient air volume can be secured for the rear seats without increasing the vehicle longitudinal dimension. Therefore, the vehicle air conditioner 1 can be downsized in the vehicle front-rear direction.
In the air conditioning device 1 for a vehicle according to the present embodiment, since the front-seat foot opening portions FF1 and FF2 open in the vehicle width direction, the cross section of the rear-seat foot tunnel 700 can be sufficiently obtained, and a more sufficient air volume can be secured for the rear seat.
(example of the construction of foot damper of air conditioner for vehicle)
with reference to fig. 2, 9, and 10, a description will be given of a configuration example of the foot damper 18 applied to the vehicle air conditioner 1 according to the present embodiment.
Here, fig. 9 is an outer perspective view showing a structural example of the foot damper 18 employed in the vehicular air conditioning device 1 of the embodiment; fig. 10 is a back side (back side) perspective view.
As shown in fig. 2, the air-conditioning case 4 is provided with a foot damper 18 for opening and closing a foot opening F communicating with the front-seat foot openings FF1 and FF2 and the rear-seat foot openings RF1 and RF2, and the left and right ends 185a of the rotary shaft 185 are supported by bearings, not shown, so that the foot damper 18 can rotate.
The foot damper 18 is molded from, for example, a heat-resistant resin.
Both end portions 181a, 181b of the flap body 180 of the foot flap 18 in the vehicle width direction are bent toward the opposite side of the foot opening F.
This reduces the air resistance flowing in the left-right direction of the foot damper 18, and allows the air conditioning air to flow smoothly through the air conditioning box 4.
As shown in fig. 10, shielding portions 183a and 183b for the conditioned air are formed in regions formed by upper bases 182a and 182b at both ends 181a and 181b of the foot damper 18 and both ends 185a and 185b of the rotary shaft 185.
Accordingly, in the fully opened state of the foot damper 18 as shown in fig. 2, the shielding portions 183a and 183b prevent the air-conditioning airflow from passing upward, and the sealing performance can be improved.
As shown in fig. 9, a plurality of reinforcing ribs 186 for reinforcing the damper main body 180 are provided upright on the outer side of the foot damper 18.
In addition, a protrusion 187 for improving the mixing degree of the warm air and the cool air is formed at a substantially central portion of the damper body 180.
The present invention has been described in detail based on the embodiments, but it should be understood that the embodiments disclosed in the present specification are only examples of various aspects and the disclosed technology is not limited thereto. That is, the technical scope of the present invention is not to be interpreted restrictively according to the above-described embodiments, and the technical scope of the present invention is interpreted according to the content of the claims, and includes the technical equivalents of the claims and all the modifications within the claims.
This patent application claims priority based on japanese patent application No. 2016-.
