Description

[Detailed description of the invention] The present invention relates to a blowing device for blowing cold air or outside air in an automobile, and in particular, the invention relates to a device for blowing out cold air or outside air in an automobile, and in particular, a device for blowing cold air or outside air supplied from the air conditioner main body through a first air duct to the front part of the instrument panel. A defroster is provided in an upper portion of the instrument panel to distribute cold air or outside air from the air conditioner main body through a second air duct so that air can be distributed from the front air outlet toward the front seat occupants. The present invention relates to an improvement in a blowing device for blowing cold air or outside air in an automobile, which is capable of distributing air from a blowing outlet toward a windshield.

In the above-mentioned type of blow-off device, the air from the front blow-off port directly hits the face and torso of the front seat occupant, which is fine if the front seat occupant intentionally cools the area locally, but in other cases it may be used for a long time. If this condition continues for a long time, it will cause discomfort such as being too cold.

In vehicles that also cool the rear seats by distributing air from the front air outlet, the front seat backs become an obstacle, and the air distributed to the rear seats is only partial and small.
Uneven or poor cooling occurs in the rear seats.

The present invention has been devised by paying attention to this problem, and one embodiment thereof will be described below based on the drawings.

FIG. 1 shows the inside of a passenger car, and the front part of the instrument panel 10 has front air outlets 11, 12, 1.
3 is provided, while a defroster outlet 14 is provided in the upper part.
．． 15 (see Figure 2).

The front air outlets 11, 12, and 13 are connected to the air conditioner main body (heat exchanger and air distribution box) 20 through the first air duct 21, as shown in FIG. 3 using the front air outlet 12 as an example. On the other hand, the defroster outlets 14 and 15 are connected to the air conditioner main body 20 through the second air duct 22, as shown in FIG. 3 using the defroster outlet 14 as an example.

In addition, a first damper 23 for switching the defroster ventilation is provided at the end of the first air duct 21 on the side of the air conditioner main body 20, and a known first damper 23 for switching the defroster ventilation is provided at the end on the side of the front air outlet 11, 12, 13. A variable grill 24 is provided respectively.

This allows the first air duct 21 to flow from the air conditioner main body 20.
The cold air or outside air fed through the front outlet 11,1
Air can be distributed from No. 2 and No. 2 and No. 13 toward the occupant in the front seat F.

Therefore, in this embodiment, as shown in FIG. 3, a branch duct 25 is connected to the center of the first air duct 21, and the upper end of this branch duct 25 is provided in the upper part of the instrument panel 10. connected to the upper air outlet 16.17 (see Figure 2), while the second air outlet is connected to the first air duct 21.
By providing the damper 26, the blowing device according to the present invention is constructed.

As clearly shown in FIG. 2, the air outlet 16.17 is connected to the front air outlet 11, 12, 13 and the defroster air outlet 14.15 on both sides of the opening 18 where instruments are disposed. They are provided to extend in the lateral direction between them.

The upper part of the branch duct 25 is inclined at a predetermined angle, and cold air or outside air is blown out toward the space between the head of the passenger in the front seat F and the vehicle ceiling 30 through the branch duct 25 and the upper air outlet 16.17. Ru.

The second damper 26 is configured to be manually operated like the first damper 23, and the cold air or outside air from the air conditioner main body 20 is transferred to the first air duct 21 or the branch duct 25.
It is switched or adjusted and guided.

In this embodiment configured in this way, the first damper 23
And if the second damper 26 is in the state shown by the solid line in FIG.
The cold air or outside air from the air conditioner main body 20 is transferred to the first air duct 21. Air is blown out through the branch duct 25 from the upper air outlets 16 and 17 toward the space between the head of the passenger in the front seat F and the vehicle ceiling 30, and the vehicle ceiling 30 is unobstructed by the seatback Fa of the front seat F. , and it flows above the rear seat R.

At this time, the cold air or outside air is distributed almost uniformly over the occupants of the front seats F and rear seats R, and it falls on the occupants like Java, keeping the occupants' heads and feet warm even during long rides. state.

Note that the air that reaches the rear seat R is then discharged from the exhaust port 32 provided in the pillar 31 on the side of the rear seat to the outside of the vehicle along with the dirty air inside the vehicle, so that the air inside the vehicle is always outside air. It is also kept clean.

Moreover, if the second damper 26 is operated to the state shown in the imaginary line shown in FIG. The air blows out toward the occupants, cooling them appropriately.

Therefore, in this embodiment, if the second damper 26 is operated to an appropriate position depending on the presence or absence of a rear seat occupant or the intention of a front seat occupant, the occupant will be in a comfortable state.

In this embodiment, when the temperature inside the vehicle is relatively high, such as immediately after the vehicle is driven in the summer, the first damper 23 is set to the state shown by the solid line, and the second damper 26 is set to the state shown by the imaginary line shown. It is also possible to rapidly cool the vehicle interior, and when the vehicle interior temperature has cooled down to an appropriate temperature, the second damper 26 can be operated to the state indicated by the solid line in the figure to create a comfortable state.

In this use, cool air or outside air is always distributed to the front seat occupants, so that the front seat occupants do not always feel hot and are comfortable.

The above explanation is based on one embodiment of the present invention.The present invention is based on an embodiment of the present invention. In addition to distributing air toward the front seat occupants, cool air or outside air is supplied from the air conditioner main body through a second air duct to the windshield from a defroster outlet provided in the upper part of the instrument panel. The present invention can be implemented by appropriately modifying various blowing devices for cold air or outside air in automobiles that are capable of distributing air toward the vehicle.

In addition, when carrying out the present invention, it is also possible to construct the upper blower outlet corresponding to the upper blower outlet 16 of the above embodiment by a large number of small hole groups arranged in a horizontal direction.

It is also possible to provide an air volume adjusting means corresponding to the second damper 26 of the above embodiment in the branch duct 25 of the above embodiment.

In short, in the present invention, in the various blowing devices described above, a branch duct is connected to a part of the air duct (corresponding to the first air duct 21 in the above embodiment), and the upper end of the branch duct is connected above the instrument panel. The section is connected to an upper air outlet extending laterally between the front air outlet and the defroster air outlet, and cold air or outside air is connected to the front seat occupant through the branch duct and the upper air outlet. The first air duct or the branch duct is provided with an air volume adjusting means so that the cool air or outside air is switched or adjusted to the first air duct or the branch duct by the air volume adjusting means. Its structural feature is that it is guided by the windshield, which makes it possible to distribute cold air or outside air almost uniformly over the front seat occupants and to the rear seats. You can solve all the problems.
