Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wind direction adjustment device used in an air conditioner installed in an automobile.

(Prior Art) As a conventional airflow direction adjustment device, a heater unit H for automobiles as shown in FIGS. 1 and 2, for example, is known.

As shown in the drawing, this conventional heater unit H includes a heater core 2 disposed in a heater unit case 1, an air mix door 3 provided on the top of the heater core 2, and an air flow from the heater core 2. an air box 4 that receives the air, a bilevel door 6 provided at the inlet 5 of the air box 4, and a first air outlet that distributes and blows out the air flowing in from the inlet 5 into the same direction of inflow and the opposite direction of inflow. It had a configuration including a duct 7 and a second blowout duct 8.

In the figure, 9 is the defroster outlet, 10 is the rear heater duct connection port, B is the blower unit, and 11 is the rear heater duct connection port.
12 is a blower fan, 12 is a fan motor, 13 is an intake door, 14 is an outside air inlet, and D is a connecting duct.

Therefore, when the air control dial located inside the vehicle is set to the bi-level (B/L) position, as shown in Fig. 2, the outside air inlet 1
4 by the blower fan 11 passes through the connecting duct D → the heater core 2 → the inlet 5, and is distributed between the first blowout duct 7 and the second blowout duct 8, and is distributed to the feet of the driver's seat and the passenger seat. It blows warm air out to the side of your feet.

However, in the case of such a conventional heater unit H, although the hot air has to be blown out from the second blowing duct 8 in a direction opposite to the direction of the hot air flowing in from the inlet 5, there is no problem. Since it is not equipped with a means for regulating the wind direction, a large amount of air is blown out from the first blowing duct 7 in the same direction as the warm air flowing into the inlet 5.
There was a problem that the amount of air from the other second blow-off duct 8 was reduced.

(Object of the Invention) The present invention has been made to solve the above-mentioned problems, and its purpose is to separate the wind coming from a predetermined inflow direction from the same direction of inflow and the inflow from the same direction. To provide a wind direction adjusting device capable of distributing air to opposite directions and blowing air at substantially the same volume.

The configuration of the present invention will be explained with reference to a diagram corresponding to the claims shown in FIG. A first blow-out duct 7 and a second blow-off duct 8 that distribute and blow out air.
and an opening/closing door 6 that opens and closes the inflow port 5 by rotating around a rotation shaft 15, the first inflow port opening with the inflow port 5 facing in the direction of air blowing. 51 and a second inlet 52 opened to the second blow-off duct 8 side, and the opening/closing door 6 is formed by the first inlet 5
1, and a second opening/closing door 62, which opens and closes the second inlet 52.
A first opening/closing door 61 and a second opening/closing door 62 are provided on the same axis of the rotating shaft 15 at substantially right angles so as to regulate the blowing air direction for the first blowing duct 7 and the second blowing duct 8. It is something.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.
In describing this embodiment, a heater unit for an automobile will be taken as an example, and the same parts as in the conventional structure will be given the same reference numerals.

First, the configuration will be explained using the embodiment shown in FIGS. 4 and 5.

H is a heater unit, and a connecting duct D and a blower unit B are provided by flange connection at one end side opening of the heater unit case 1, forming an air control duct as a whole.

Reference numeral 2 denotes a heater core, which is arranged in an inclined manner on the heater unit H, and the air from the blower unit B becomes hot air by passing through the heater core 2.

Reference numeral 3 denotes an air mixer door, which is installed at the top of the heater core 2. By changing the opening degree of the air mixer door 3, it can be used to blow only cold air (lower end position) or to blow cold air. The switch is made to switch between blowing hot air and warm air (middle position) and blowing only warm air (upper end value).

An air box 4 is provided at the lower end of the heater unit case 1 and receives the temperature passing through the heater core 2.

Reference numeral 51 denotes a first inlet, which is opened in the air box 4, and this first inlet 51 faces in the air blowing direction.

Reference numeral 52 denotes a second inlet, which is opened on the upper surface of a second blow-off duct 8, which will be described later, and is connected to and opened in a direction perpendicular to the first inlet 51.

Reference numeral 61 denotes a first opening/closing door, which opens and closes the first inlet 51;
1 is fixed to a rotating shaft 15 at its lower end.

62 is a second opening/closing door that opens and closes the second inlet 52;
2 is also fixed to the rotation shaft 15.

The opening/closing doors 61 and 62 are provided on the same axis of the rotating shaft 15 at approximately right angles, and are opened simultaneously at the same opening degree by the rotation of the rotating shaft 15, and are rotated approximately 45 degrees. In the open state, the first blowout duct 7, which will be described later,
Then, the blowing air direction is regulated for the second blowing duct 8.

Reference numeral 7 denotes a first blowout duct, which blows out the air flowing in from the first inlet 51 in the same direction as the inlet.

Reference numeral 8 denotes a second blow-off duct, which blows out the wind flowing from the second inlet 52 in the opposite direction of inflow, and is disposed in communication with the first blow-off duct 7 on the same horizontal axis.

In the figure, 9 is a defroster outlet, 16 is a differential door, 17 is a ventilator outlet, 18 is a vent door, 10 is a rear heater duct connection port, 11 is a blow fan, 12 is a fan motor, 13 is an intake door, and 14 is an outside air intake. The mouth is the 19th air intake port.

Next, the effect will be explained.

Bi-level (B/L) air control dial located on the instrument panel inside the vehicle.
When set to the position, as shown in FIG. 5, the first opening/closing door 61 and the second opening/closing door 62, which are normally closed as a ventilation duct, rotate about the rotation axis 15, and the first The inlet 51 and the second inlet 52 are opened at the same opening degree.

Then, from the outside air inlet 14 to the blower fan 11
The air sent by the air passes through the connecting duct D → the heater core 2 → the first inlet 51 (second inlet 52), and then passes through the first opening/closing door 61 and the second opening/closing door 62.
The hot air is distributed according to the wind direction regulation, and hot air is blown out from the first blow-off duct 7 and the second blow-off duct 8 to the feet of the driver's seat and the feet of the passenger seat.

In other words, the wind flowing in from the first inflow port 51 is guided in its direction along the door surface of the first opening/closing door 61 toward the first blowout duct 7, and also flows in from the second inflow port 52. The wind is guided and regulated in its inflow direction by the first opening/closing door 61, and then guided and regulated in its blowing direction in a direction opposite to the inflow direction by the second opening/closing door 62.

Because of this wind direction regulation and because the opening degrees of the first inlet 51 and the second inlet 52 are almost the same, and the same amount of air flows in, the airflow from the first blowout duct 7 and the second blowout duct 8 is almost the same. It can blow out a large amount of warm air.

Incidentally, since the opening/closing doors 61, 62 are provided coaxially with the rotating shaft 15, the opening/closing drive of the doors using a negative pressure actuator or the like can be performed in the same way as in the conventional case.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments. For example, the embodiments have shown an automobile heater unit, but other than automobile air conditioners. The present invention may be applied to a blow-out portion of a vehicle, or may be further applied to a wind direction adjusting device of an air conditioner other than a vehicle.

Further, the wind is not limited to warm air, and may be cold air, wind from outside, or the like.
