JP5621161B2 - Air outlet structure for vehicle air conditioner - Google Patents

Description

  In the present invention, the air outlet provided on the upper surface of the instrument panel is configured so that the direction of the air blown from the air outlet is inclined obliquely upward and rearward so that the air blown from the air outlet is directed toward the rear of the vehicle. The present invention relates to an air outlet structure of a vehicle air conditioner.

  As a blower outlet structure of a conventional vehicle air conditioner, for example, the one shown in Patent Document 1 below is known. This conventional air outlet structure prevents the generation of a negative pressure region at the lower part of the air outlet by arranging an air vent hole extending from the back side of the instrument panel to the front side at the rear end of the air outlet. The wind blown from the exit is to be supplied to the rear of the vehicle in the direction as designed.

Japanese Utility Model Laid-Open No. 5-16525

  In the conventional air outlet structure, the direction of the wind blown out from the air vent hole is substantially parallel to the direction of the air blown out from the air outlet, so that it is attracted by the fast flow, and the wind blown out from the air vent hole creates the same high-speed flow. easy. As a result, a negative pressure is generated in the lower part of the air vent hole. In addition, at the lower part of the air vent hole, there is not enough space for the wind blown out from the air vent hole to swirl toward the instrument panel and merge again with the original wind flow, so the wind flow is stagnant For this reason, the configuration is such that a negative pressure is more likely to be generated in the lower portion of the air vent hole. When negative pressure is generated in the lower part of the air vent hole, not only the air blown out from the air vent hole but also the air blown out from the air outlet is attracted to the negative pressure side. The direction was not secured, and there was room for improvement.

In addition, as another method for preventing the occurrence of negative pressure at the rear end portion of the air outlet, for example, (1) a structure in which the rear end portion of the air outlet is greatly swung inside the instrument panel, (2) A large hole is made in the rear end of the air outlet, and (3) a structure in which the air outlet is protruded from the instrument panel.
However, (1) has a problem that it is difficult to secure a space in relation to the built-in objects. As for (2), since the hole is large, it is necessary to take measures to prevent falling objects and the hole is visible to the occupant, so the appearance of the instrument panel is deteriorated. Regarding (3), there is a problem that the appearance of the instrument panel is considerably deteriorated.
As described above, the object of the present invention is to design the wind at the outlet by ensuring the space in the instrument panel and suppressing the negative pressure at the rear end of the outlet without impairing the appearance of the instrument panel. It is providing the blower outlet structure of the air conditioning apparatus for vehicles which can be supplied in the usual direction.

  The characteristic configuration of the present invention is that the air outlet provided on the upper surface of the instrument panel is configured such that the direction of the air blown from the air outlet is inclined obliquely rearward and upward, and the wind blown from the air outlet is the rear part of the vehicle. An air conditioner for a vehicle air conditioner that is directed to the rear end of the air outlet, and a vertical wall portion that extends from the rear end of the air outlet toward the inside of the instrument panel, and A step portion is formed by a bottom portion extending from the lower end of the vertical wall portion toward the rear of the vehicle, and a wind different from the wind blown from the air outlet to the step portion in a direction intersecting with the direction of the air blown from the air outlet. It is in the point provided with the inlet which supplies.

[Action and effect]
As in this configuration, a step portion is formed at the rear end portion of the air outlet by a vertical wall portion that extends from the rear end portion of the air outlet toward the inside of the instrument panel and a bottom portion that extends from the lower end of the vertical wall portion toward the rear of the vehicle. By forming the above, a space is secured for turning the wind blown from the blowout outlet to the instrument panel side, and joining the original wind flow again and discharging it. Thereby, since the flow of the wind from a blower outlet does not stagnate, it is hard to produce the negative pressure in a step part.

  Furthermore, according to this configuration, since the wind that is different from the wind blown from the blower outlet is supplied to the step portion in a direction intersecting with the direction of the wind blown from the blower outlet, Even if it is attracted by the wind blown out from the outlet, it does not form a parallel fast flow, and the negative pressure at the stepped portion is more unlikely to be generated, and the wind at the outlet can be supplied in the designed direction.

  Further, according to this configuration, the instrument panel includes a step portion for ensuring a space for the wind to flow and an introduction port for supplying wind to the step portion in a direction crossing the direction of the wind blown from the blowout port. There is no need to have a structure that pierces inside, a structure in which a large hole is formed in the rear end of the blowout port, or a structure in which the blowout port protrudes from the instrument panel. Therefore, a space in the instrument panel can be secured, and the appearance of the instrument panel is not impaired.

It is a side view of a vehicle provided with the blower outlet structure of the air conditioner for vehicles of the present invention. It is a front view of an instrument panel provided with the blower outlet structure of the air harmony device for vehicles of the present invention. It is a vertical side view of the blower outlet structure of the vehicle air conditioner of this invention. It is a front view of the blower outlet structure of the vehicle air conditioner of this invention. It is a vertical side view of the blower outlet structure of another form.

Hereinafter, as an embodiment of the present invention, an example in which the present invention is applied to an upper outlet will be described with reference to the drawings.
