Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular air-conditioning blower installed at an air-conditioning air outlet in a vehicle compartment, and more particularly to a housing that rotates around a horizontal axis inside an air-conditioning case of the air-conditioning blower. The present invention relates to a vehicle air-conditioning blow-out device that eliminates the reduction of blow-out efficiency and the generation of noise due to the rotation of the vehicle.

[0002]

2. Description of the Related Art Normally, it is difficult to secure a large air outlet area because air conditioning air outlets in a vehicle compartment are subject to various restrictions, and therefore the air blown out is locally localized. Therefore, an air conditioning blowout device for a vehicle is conventionally equipped with a device for freely adjusting the wind direction. For example, for the left and right wind directions, a large number of vertical louvers that are the left and right wind direction adjustment blades are installed side by side inside the air conditioning blower, and the left and right wind directions are adjusted by turning them to the desired angle all at once via links. I have to. On the other hand, there are some which are provided with a large number of horizontal louvers that rotate up and down with respect to the up and down wind direction. For example, as disclosed in Japanese Utility Model Laid-Open No. 63-43034, an air conditioning air outlet and a frame on the inner front surface are provided. There is one in which an air conditioning case body accommodating a cylindrical housing is installed so that the housing can be rotated around a horizontal axis in the air conditioning case.

FIG. 4 shows an example having substantially the same structure as the air-conditioning blow-out device disclosed in the above publication. According to FIG. 4, the front part of the air-conditioning case body 11 shows a part of a cylindrical space when viewed from the side. None, a frame-shaped housing 14 having a vertical louver 12 and a horizontal louver 13 is rotatable in the same space around a horizontal axis. The vertical louver 12 has the upper and lower shafts of the housing 1
The vertical louvers 12 are rotatably supported by the upper and lower wall surfaces of 4, and each vertical louver 12 is rotatably connected by one vertical louver interlocking link 15, and one vertical louver is operated by operating the knob 16 left and right. When 12 is rotated right and left, all the vertical louvers 12 are simultaneously rotated via the link 15. On the other hand, the horizontal louver 13 is horizontally fixed to the front surface of the housing 14, and when adjusting the up and down wind direction, the housing 14 is turned up and down around the left and right shafts inside the air conditioning case body 11. I am trying to do it.

[0004]

The air conditioning blower disclosed in the above publication is also the same, but in the conventional air conditioning blower for a vehicle having the air conditioning case body and the housing as described above, a rectangular frame is used. Since all the corners of the rectangular housing are formed into a completely rectangular frame shape, if this is rotated downward, for example, inside the air conditioning case body, the rear end of the bottom wall 14a of the housing 14 as shown in FIG. There rises from the bottom wall 11a of the air conditioning case body 11 to the height of L _2, the residence portion of the air is generated in the portion, further expanded noise eddy flow is generated, lowering the blowing efficiency air.

The present invention solves the above-mentioned problems of the prior art, and the object thereof is to prevent noise from expanding even when the frame-shaped housing is rotated up and down inside the air-conditioning case body, and at the same time reduce the air blowing efficiency. An object of the present invention is to provide a vehicle air-conditioning blow-out device that does not operate.

[0006]

In order to achieve the above object, the present invention has a frame-shaped housing in which a horizontal louver group is fixed to the front surface, and a vertical louver group for adjusting the wind direction that pivots in conjunction with the rear portion is pivotally supported. And an air conditioning case body that houses the housing in the front part and horizontally pivots the support shafts at the left and right ends of the housing, and cuts out either the upper or lower part of the rear end of the housing or the upper and lower parts, A vehicle air-conditioning blow-out device is characterized mainly in that a cutout portion parallel to the rotation axis is formed and a vertical louver interlocking link is accommodated in the cutout portion.

[0007]

When adjusting the left and right wind direction, one vertical louver is rotated to the left and right by operating the knob protruding from the front of the device to the left and right as in the conventional case. To rotate all vertical louvers to the left and right all at once. When adjusting the wind direction to either the up or down direction, rotate the housing in either the up or down direction, the horizontal louver faces in either the up or down direction, and the air blown out from the air outlet is removed. It goes diagonally upward or downward. At this time, according to the present invention, since one or both of the upper and lower ends of the rear end of the housing are notched portions, the air sent from the rear of the air conditioning case body may not be disturbed at the inlet of the housing. Instead, it smoothly flows forward, and does not cause noise due to generation of vortex or lowering of blowing efficiency as in the conventional case. Further, as a subordinate, since the vertical louver actuating link is housed inside the notch, the link cannot be seen from between the louvers when the housing is facing the front, and the appearance is improved.

[0008]

The present invention will be described in detail below with reference to illustrated embodiments. 1 to 3 show a typical embodiment of the present invention,
FIG. 1 is an overall perspective view showing the appearance of a vehicle air-conditioning blowout device, FIG. 2 is a sectional view taken along the line AA in FIG. 1, and FIG. 3 is a perspective view of a housing, which is a main component of the present invention, seen from the rear surface. It is a figure.

The air conditioning case body 1 is composed of a case body 1a and a finisher 1b. The case body 1a is a rectangular tubular body having a rectangular cross section as a whole, and the upper and lower wall portions 1a 'of the front portion thereof are bulged in an arc shape. The upper and lower wall portions 1a 'are similarly fitted with a finisher 1b in which the upper and lower wall portions 1b' bulge in an arc shape. Therefore, the front part of the air conditioning case body 1 forms a part of the cylindrical space when viewed from the side.

In this partial cylindrical space, a frame-shaped housing 4 having a vertical louver 2 and a horizontal louver 3 is pivotally mounted on the left and right side walls of the air conditioning case body 1 so as to be rotatable about a horizontal axis. . Therefore, the frame-shaped housing 4 has a substantially rectangular frame shape as shown in FIG. 3, and the outer surfaces of the upper and lower walls thereof have an arc shape having substantially the same curvature as the upper and lower wall portions 1a ′ and 1b ′ of the air conditioning case body 1. The support shaft 4a projects from the center of the left and right side surfaces of the support shaft 4a.

On the front surface of the housing 4, horizontal louvers 3 are fixed in parallel at a predetermined interval, and a large number of vertical louvers 2 are vertically arranged side by side in the housing 4 at a predetermined interval. The upper and lower shaft portions 2a and 2b are rotatably supported on the upper and lower wall surfaces of the housing 4. The lower end edge of the rear end of the frame-shaped housing 4 is cut out as shown by the hatched portion in FIG. 3 to form a cutout 4b parallel to the rotation axis. Therefore, the rear end lower end 2c of each vertical louver 2 projects into the notch 4b, and the rear end lower ends 2c are rotatably connected by one vertical louver interlocking link 5. At this time, the vertical louver interlocking link 5 is also housed inside the cutout portion 4b.

The housing 4 having such a structure is shown in FIG.
As indicated by the phantom line, the air-conditioning case body 1 is housed in the partially arcuate space, and the left and right support shafts 4a are rotatably supported by the left and right side walls of the case body 1a.

In the air-conditioning and blowing device of the present invention thus assembled, when one vertical louver 2 is rotated left and right by operating the knob 6 protruding from the front of the device to the left and right,
All the vertical louvers 2 are simultaneously rotated right and left via the link 5. In addition, the housing 4 is used to direct the wind downward.
Is rotated downward as shown by the solid line in FIG. 3, the horizontal louver 3 is directed downward, and the air blown out from the air outlet is directed obliquely downward. At this time, according to the present invention, since the lower end of the rear end of the housing 4 is the cutout portion 4b, the lower wall surface of the rear end of the housing 4 has a height L which is slightly smaller than that of the prior art.
_{Since 1} does not project inwardly from the lower wall surface 1a 'of the case body 1a, the air sent from the rear of the air conditioning case body 1 does not interfere with the inlet of the housing 4 and flows smoothly forward, unlike the conventional case. Noise caused by the generation of eddies
Alternatively, the blowing efficiency does not decrease.

Further, as a subordinate, since the vertical louver actuating link 5 is housed inside the cutout portion 4b,
When the housing 4 is turned to the front, the link 5 cannot be seen from between the louvers, and the appearance is improved. Although the notch 4b is formed at the lower end of the rear end of the housing 4 in the above description, it may be formed at the upper end of the rear end of the housing 4, or may be formed at both the upper and lower ends of the rear end. It is possible.

[0015]

As is apparent from the above description, according to the vehicle air-conditioning blow-out device of the present invention including the air-conditioning case body and the housing, one or both of the upper and lower ends of the rear end of the housing can be provided. Since the notch portion parallel to the rotation axis of the housing is formed, the air flow sent from the rear of the housing does not become a vortex flow at the inlet of the housing, does not increase noise, and at the same time does not reduce the blowing efficiency. Further, according to the present invention, since the link for operating the vertical louver can be accommodated in the cutout portion, the link cannot be seen when the housing is directed to the front side, which is also excellent in appearance.
