[0012]

Next, the operation of the air blowing device for an instrument panel according to the first embodiment configured as described above will be described.

The operation of the air conditioner 24 is started by a required switch operation on the operation section 26, and the temperature is adjusted to a predetermined temperature by selecting the temperature adjustment dial 28, the wind direction adjustment lever 30 and the like to a desired setting mode. The heated conditioned air is blown out from the front air outlets 34, 34, the upper surface air outlet 38, and the like. Then, when the setting mode of the temperature-controlled air selected by the wind direction adjustment lever 30 is set to a mode in which blowing of the temperature-controlled air from the upper surface air outlet 38 is prohibited (for example, an “air-conditioning mode”). The lid member 40 linked to the wind direction adjustment lever 30 is
The opening of the air outlet 38 is completely closed by controlling the posture in a substantially horizontal state with the rear edge moved downward, and the opening is contoured integrally with the upper surface of the instrument panel 10 in appearance. Are almost invisible.

Therefore, in the "air-conditioning mode", the contour of the upper air outlet 38 is not reflected on the windshield 20 even if the sunlight enters from above the front.
The projection of the upper air outlet 38 does not obstruct the view or cause poor visibility. Further, even if the booth temporarily placed on the upper surface of the instrument panel 10 moves in the direction of the upper air outlet 38 due to vibration of the vehicle body or the like,
Since the lid member 40 completely closes the opening,
The boots are preferably prevented from falling into the upper air outlet 38. Further, dust or the like may be

40B are individually controlled for swinging. That is, in the air blowing device of the modified example, the “defrost mode” is a “full blowout mode” in which air is blown over the entire inner surface of the windshield 20, and the “left blowout mode” is that air is blown on the inner left half of the windshield 20. In this case, it is possible to select a “right side blowing mode” in which air is blown to the right half inside the windshield 20. For example, in the "full-surface blowing mode", the left half 40A and the right half 40B are simultaneously tilted by controlling each of the driving sources synchronously to completely close or open the upper surface air outlet 38. Become like In the “left side blowing mode”, only the left half 40A is tilted in a state where the right half 40B is stopped at the closed position, so that the left half of the windshield 20 is tilted.
Controlled air can be blown only to the (passenger side)
(See FIG. 6). In the “right side blowing mode”, the left half 40
By tilting only the right half 40B with A stopped at the closed position, it is possible to blow the temperature-controlled air only to the right half (driver's seat side) of the windshield 20 (see FIG. 5). .

[0018]

Operation of the Modified Example of the First Embodiment Next, the operation of the instrument panel air blowing device according to the modified example of the first embodiment will be described.

By the required switch operation on the operation unit 26, the left and right halves 40A and 40B constituting the cover member 40 are connected to the rear edges of the upper air outlet 38 in the state of being set to the "air conditioning mode". The opening of the air outlet 38 is completely closed by lowering the position of the opening to a substantially horizontal state, and the opening of the opening is integrally formed with the upper surface of the instrument panel 10 in appearance. Are almost invisible. Therefore, in the air-conditioning mode, even when sunlight is introduced from the upper front, the contour of the upper surface air outlet 38 is not reflected on the windshield 20, so that the projection of the upper surface air outlet 38 becomes obstructive. And no poor visibility. Further, even if the booth temporarily placed on the upper surface of the instrument panel 10 moves in the direction of the upper air outlet 38 due to vibration of the vehicle body or the like, the left and right halves 40A and 40B cover the entire opening. The upper surface air outlet 38 of the booth.
Falling into the inside can be suitably prevented. Further, dust and the like are supplied from the upper air outlet 38 to the second air outlet duct 3.
6 does not invade.

If fogging occurs entirely on the inner surface of the windshield 20 or frost adheres to the entire outer surface, the wind direction adjusting lever 30 of the operation unit 26 is set to “whole air blowing”. Mode ". That is,
Since the upper surface air outlet 38 is completely opened, the air sent through the second air outlet duct 36 is blown from the upper surface air outlet 38 to the entire inner surface of the windshield 20. In the “entire air blowing mode”, the booths temporarily placed on the upper surface of the instrument panel 10 are removed from the upper air outlet 38 by vibration of the vehicle body or the like.
Is moved by the left half 40A or the right half 40B in the inclined state, it is possible to suitably prevent the booth from falling into the upper surface air outlet 38.

When fogging occurs on the right side of the inner surface of the windshield 20 or when frost or the like adheres to the right side of the outer surface, the wind direction adjusting lever 30 of the operation unit 26 is set to " Set to right side blowout mode. That is, since the right half of the upper surface air outlet 38 is opened, the temperature-controlled air sent through the second air outlet duct 36 blows from the right side of the upper surface air outlet 38 to the right inside of the windshield 20. (See FIG. 5). In addition,
In such a “right-side blowing mode”, even if the booth temporarily placed on the upper surface of the instrument panel 10 moves in the direction of the upper-side air outlet 38 due to vibration of the vehicle body or the like, the slanted state is maintained. Since it is received by the right half 40B and the left half 40A in the horizontal state, it is possible to suitably prevent the booth from falling into the upper surface air outlet 38.

Further, when fogging occurs on the left portion of the inner surface of the windshield 20 or when frost or the like adheres to the left portion of the outer surface, the wind direction adjusting lever 30 of the operation unit 26 is set to " Set to left side blowing mode. That is, since the left half of the upper surface air outlet 38 is opened, the temperature-controlled air sent through the second air outlet duct 36 blows from the left side of the upper surface air outlet 38 to the inner left portion of the windshield 20. (See FIG. 6). In addition,
In such a “left-side blowing mode”, even if the booth temporarily placed on the upper surface of the instrument panel 10 moves in the direction of the upper-surface air outlet 38 due to vibration of the vehicle body or the like, the above-mentioned horizontal state is maintained. Since the right half 40B and the left half 40A in the inclined state are received, it is possible to suitably prevent the booth from falling into the upper surface air outlet 38.

The left half 40 of the lid member 40
Regarding the operation modes of A and the right half 40B, it is possible to automatically control the drive source by a microcomputer so that the respective opening and closing operations are automatically performed according to a preset program. As an example, when the wind direction adjustment switch 30 is switched to the “defrost mode”, the windshield 20 is first set to the “right side blowing mode” and
Intensively removes the fogging and frost on the driver's side in a single hour, and then changes the setting to "left side blowing mode" several minutes later to concentrate the fogging and frost on the front windshield 20 on the front passenger's side. It is possible to consider a program that removes it.
According to such operation control, since defrosting on the driver's seat side can be performed in a short time, there is an advantage that the departure preparation time can be shortened, especially in the early morning of winter.

Further, in the flap-shaped lid member 40 (left half 40A and right half 40B) exemplified in the first embodiment and the modified example, the inclination angle at which the upper surface air outlet 38 is opened is changed. Thus, it is possible to change the blowing direction of the temperature-controlled air guided by the lower surface of the lid member 40. For example, when the lid member 40 is stopped in a state where the inclination angle is small, the temperature-controlled air is intensively blown downward inside the windshield 20, and when the inclination angle is large, the lid member 40 is stopped. Is stopped, the temperature-controlled air blows vertically upward, and is intensively blown upward and inside the windshield 20.
