BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a defroster device.

[0002]

2. Description of the Related Art As shown in FIG. 3 , an instrument panel 1 provided in a front portion of a vehicle compartment is used to melt frost adhering to a windshield 2 in winter or when the windshield 2 becomes cloudy. In order to remove fogging, a defroster device 4 is provided which blows out air for air conditioning from an opening 3 formed in the instrument panel 1 toward the front window glass 2.

As shown in FIGS. 4 and 5, the conventional defroster device 4 includes a duct 5 on the inside (lower surface) of the instrument panel 1. The duct 5 has a substantially U-shaped cross section and a shape extending in the left-right direction along the front window glass 2, and an upper edge thereof is fixed to the inner surface of the instrument panel 1. Further, an inlet 6 for compressed air is formed at a lower position of the middle portion in the left-right longitudinal direction.

Further, the opening 3 is formed in the instrument panel 1 at a position inside the duct 5 along the duct 5, and the opening 3 has a rectangular cylindrical shape having a rectangular blowing hole 7. A plurality of guides 8 are fixed. The cylindrical guide 8 is formed at a required inclination angle in order to set the wind direction so that the compressed air is directed toward the front window glass 2.

FIG. 6 shows another example of the prior art, in which a cylindrical guide 8 is provided inside the instrument panel 1 so that the opening 3 and the blowout hole 7 are aligned with each other. otherwise it has exactly the same configuration as FIG. 5.

[0006]

However, the above-mentioned conventional apparatus has a structure in which a plurality of cylindrical guides 8 are fixed to the positions of the openings 3 of the instrument panel 1 inside the duct 5, so that the cylindrical The shape guide 8 itself has a complicated shape, and the number of parts also increases, and thus there is a problem that the manufacturing cost increases.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a defroster device which can simplify the configuration and reduce the number of parts and can set an intended wind direction.

[0008]

SUMMARY OF THE INVENTION According to the present invention, an instrument panel having an opening at a front portion of a passenger compartment and having an opening for blowing air-conditioning air toward a front windshield is provided on a front side wall of the passenger compartment. The opening on the rear side wall is
At the required interval, in front of the cabin and behind the cabin,
The space surrounding the opening with the instrument panel
A duct to be formed is provided , and on the inner lower surface of the instrument panel inside the duct, an inclined guide surface portion that sets the blowing angle of the compressed air substantially coincides with one of the front and rear side surfaces of the opening, and a mounting portion. Guide plate,
The guide plate the attachment portion is the mounting <br/> only ash through such extension line of the guide surface for guiding the pumping air matches the inclined surface of the opening edge portion of the.

[0009]

In the defroster device of the present invention, the guide plate provided so that the compressed air introduced into the duct substantially coincides with only one of the front and rear side surfaces of the opening is directed toward the windshield while setting the wind direction. Is blown out.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

[0011] Figure 1 is an embodiment of the present invention, figure 3
6 are the same as those in FIG.

On the lower surface inside the instrument panel 1,
The front side wall 12 and the rear side wall 13 are open
At a required interval from 3, move away from the front of the cabin and back of the cabin.
Surround the opening 3 with the instrument panel 1
A duct 5 that forms a space is attached to the inside of the instrument panel 1 inside the duct 5,
The extension of the guide surface of the guide plate 11 is in front of the cabin of the opening 3.
The guide plate 11 is mounted so as to match the inclined surface of the edge of the side surface 9 . The guide plate 11 has an inclined guide surface having a required inclination angle so as to set the direction of the compressed air blown out from the duct 5 and an attachment portion to be attached to the instrument panel 1, and is formed long in the left-right direction. It has a length substantially equal to that of the opening 3. In the figure, reference numeral 10 denotes the opening 3
The rear side of the cabin.

According to the above embodiment, the compressed air introduced into the duct 5 is blown out from the opening 3 toward the front window glass 2 while the wind direction is set by the guide plate 11, so that the front window glass 2 Head for
The directivity of the wind direction can be sufficiently ensured.
The instrument panel 1 is separate from the duct 5
Instrument panel because it is attached to the lower surface of
1 can increase the surface rigidity .

FIG. 2 shows another embodiment of the present invention .
Inside lower surface of Lee Nsu torr instrument panel 1, and Example
A duct 5 having the same structure is attached, and an extension of the guide surface of the guide plate 14 is provided on the lower surface inside the instrument panel 1 inside the duct 5 so that the rear surface of the opening 3 is formed in the rear side of the passenger compartment.
The guide plate 14 is mounted so as to match the inclined surface of the edge of the ten . The guide plate 14 has an inclined guide surface having a required inclination angle so as to set the direction of the compressed air blown out of the duct 5 and an attachment portion to be attached to the instrument panel 1, and is formed to be long in the left-right direction. It has a length substantially equal to that of the opening 3.

[0015] According to the above embodiment, the pumping air introduced into the duct 5, while being set wind direction by the guide plates 14, since it is blown out from the opening 3 on the front window glass 2, and Example Similarly front wing
The directionality of the wind toward the glass 2 can be sufficiently secured,
The guide plate 11 is separate from the duct 5 and
Instrument panel 1
The surface rigidity of the torque panel 1 can be increased .

Incidentally, the defroster device of the present invention is not limited to the above-described embodiment, and fins for uniformly distributing the compressed air in the longitudinal direction of the opening are formed integrally with the guide plate. It goes without saying that various changes may be made without departing from the scope of the present invention.

[0017]

As described above, according to the defroster device of the present invention, the structure is simple, the number of parts can be reduced, the production cost can be reduced, and the extension of the guide surface for guiding the compressed air of the guide plate. be but consistent with the inclined surface of the opening edge
Runode, the directivity of desired sufficient wind direction can be 俣持, moreover since the duct and the guide plate are separate bodies
Guide plates increase the surface rigidity of the instrument panel.
And various other excellent effects can be achieved.
