Abstract

PURPOSE:To provide an air diffuser where as formation of deflection passage and control of wind shift can be made by movable vanes, the number of parts can be decreased and construction can be simplified, whose cost can be lowered, and which is easy to assemble because there is no need to form holes in an instrumental panel separately up and down. CONSTITUTION:A plurality of movable vanes 14 are pivoted in a flow passage of a case body 1. In the case body 1, the movable vanes 14 are inclined with respect to a direction of an airstream which flows through the flow passage 9, so that the adjacent movable vanes 14 are doubled with each other at their terminals. Thus the doubled movable vanes 14 form a deflection passage 10, through which airstream deflected by the doubled movable vanes 14 is diffused out of a space between the movable vanes 14 and the inside of the case body 1.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air outlet for an air conditioner for automobiles.

[0002]

2. Description of the Related Art A conventional air outlet device of this type is shown in FIGS. In this air outlet device, the front side outlet part 41 and the upper side outlet part 42 are formed separately, and the front side outlet part 41 is provided with a plurality of vertical and horizontal movable blades 43 and 46. The shutter valve 44 is provided behind the shutter valve 44. A horizontal fixed blade 48 is provided at the upper outlet 42, and a shutter valve 50 is provided behind this. Also,
An outlet duct 49 is connected to the rear portion of the front side outlet portion 41 and the upper side outlet portion 42.

The blown air F flowing through the blowout duct 49
To the front and upper air outlets 41, 42, and the front air outlet 41 blows out in a predetermined direction by rotating the vertical and horizontal movable blades 43, 46, and the upper air outlet 42 uses the horizontal fixed blades. It was blowing in an upward angle direction of 48.

A conventional air outlet device is disclosed in Japanese Utility Model Publication No. 3-26971. In the one disclosed in Japanese Utility Model Publication No. 3-26971, a grill is provided so as to be vertically movable in an air passage formed by an outer frame forming an air outlet, and the air passage is connected to an upper side of the air outlet. A bypass outlet is provided, and the grill is rotated upward to short-circuit the air passage to the bypass outlet.

[0005]

However, in the conventional air outlet device shown in FIGS. 8 to 10, the front air outlet portion 41 and the upper air outlet portion 42 are formed separately, and moreover, The shutter valves 44 and 50 are required for each of the air outlets 41 and 42, and the number of parts is large, and the configuration is complicated, and the shutter valve 44 is closed to blow out only the upper air outlet portion 42. As shown in FIG. 10, when the front air outlet 41 is closed, turbulent flow is generated behind the shutter valve 44, the flow energy of the air is reduced, and the flow energy of the front air outlet 41 is blown upward. There was a problem in that it could not be effectively converted to the outlet section 42 side. The same problem occurs when only the front air outlet 41 is blown out. In order to solve this problem, it is conceivable to shift the position of the shutter valve 44 to the position of the line C-C in FIG. 10. If this is done, the turbulent flow when the shutter valve 44 is closed disappears, but the shutter Shutter valve 4 when valve 44 is opened
There is a problem that the fluid No. 4 protrudes into the blowout duct 49 to increase the flow resistance.

Further, the front air outlet portion 41 and the upper air outlet portion 4
2 are formed separately from each other, and these front side air outlets 41
Between the upper outlet part 42 and the upper outlet part 30c for preventing deformation.
Since m or more is required, it is necessary to separately form the holes to be formed in the instrument panel in order to attach the air outlet device, which is a problem in that the assembly of the air outlet device becomes troublesome.

Further, in the air outlet device disclosed in Japanese Utility Model Publication No. 3-26971, when the grill is turned upward to short-circuit the air passage to the bypass outlet,
Blast is blown from both the blow-off port and the bypass blow-off port, and there is a problem that the wind is diffused and spot blowing cannot be performed.

The present invention has been made by paying attention to the above-mentioned problems, and an object of the present invention is to form a deflection flow path and control the wind direction by means of movable blades. It is possible to provide an air blowout device that is easy to assemble because the number of holes is reduced, the structure is simplified, and the cost can be reduced, and it is not necessary to separately form the holes to be formed in the instrument panel in the upper and lower parts.
