Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a duct for a vehicle air conditioner. More specifically, it relates to a duct that passes above a glove box attached to the lower part of the instrument panel.

[0002]

[Prior Art]

 This type of air conditioner is equipped with air conditioners such as a cooler unit and a heater unit, and a part of the air blown from this air conditioner passes through ducts provided in the instrument panel and is placed near the ends of the instrument panel. It is discharged from a side resistor installed toward the room. Conventionally, as a structure of an air-conditioning duct that blows out air from a place other than a side register, for example, it branches from a duct body passing above a grab box attached to the lower part of the instrument panel and covers the opening at the top of the glove box. It is disclosed that an air outlet is extended behind the glove box so as to face downward and blows air to the feet of passengers (Shokai Sho 13-13809).

[Problems to be solved by the device]

However, in the structure of the conventional air-conditioning duct, there is a problem that it is difficult to maintain a comfortable air-conditioning state in the vehicle when cold air is blown out to the occupant's feet during cooling. In addition, the above-mentioned conventional duct structure cannot adjust the wind direction and only blows air to the foot of the occupant, which is insufficient for ventilating the inside of the vehicle.

The object of the present invention is to maintain a comfortable air-conditioning condition inside the vehicle not only during heating and ventilation but also during cooling, and at the same time increase the air flow in the vicinity of the occupant seated without adjusting the wind direction. , It is to provide a duct for a vehicle air conditioner that can enhance the ventilation performance inside the vehicle.

[0005]

Means for Solving the Problems A configuration of the present invention for achieving the above object will be described with reference to FIGS. 1 and 2 corresponding to an embodiment. The present invention is for a vehicle that guides air blown out from an air conditioner 12 provided in an instrument panel 11 of a vehicle to side registers 17 and 18 mounted toward the inside of the vehicle near both ends of the instrument panel 11. It is an improvement of the duct of the air conditioner. The characteristic structure is that the upper edge of the glove box 26 and the instrument panel 11 facing the upper edge of the glove box 26 are provided on the peripheral surface of the duct main body 23a located above the glove box 26 attached to the lower part of the instrument panel 11. It is where the air outlet 23b facing the gap 28 with the lower edge is formed.

[0006]

[Action]

 The temperature-controlled air is blown from the air outlet 23b facing the gap 28 toward the abdomen or thigh of the seated occupant. This promotes ventilation inside the vehicle without the occupants adjusting the wind direction.

[0007]

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 2 and 3, a cooler unit 13 and a heater unit 14 which are air conditioners 12 of an air conditioner are provided in an instrument panel 11 of the vehicle. These units 13 and 14 are connected via ducts 21 to side registers 17 and 18 on the driver's seat side and the passenger's seat side. The inlet of the cooler unit 13 communicates with the outlet of the blower 19 that sends air outside or inside the vehicle to the cooler unit 13 or the heater unit 14, and the outlet of the cooler unit 13 communicates with the two flow paths 13a and 13b.

The inlet of the heater unit 14 communicates with one flow passage 13a of the cooler unit 13, and the outlet of the heater unit 14 communicates with the flow passage 14a. This flow path 14a joins with the other flow path 13b of the cooler unit 13, and the register outlet 24 is formed therein. The side register 17 on the driver's seat side is installed near the right end of the instrument panel 11 with the opening facing the inside of the vehicle, and the side register 18 on the passenger side is installed near the left end of the instrument panel 11 with the opening facing the inside of the vehicle. (Fig. 3). The duct 21 includes a driver-side duct 22 that communicates the register outlet 24 and the driver-side side register 17, and a passenger-side duct 23 that communicates the register outlet 24 and the passenger-side side register 18. Prepare As shown in FIG. 1, the passenger side duct 23 is installed near the inner top of the instrument panel 11 and above the glove box 26 attached to the lower part of the instrument panel 11.

The characteristic structure of this embodiment is that a gap 28 is formed between the upper edge of the glove box 26 and the lower edge of the instrument panel 11 facing the upper edge of the glove box 26 on the peripheral surface of the duct body 23 a of the passenger side duct 23. It is where the facing air outlet 23b is formed. Specifically, the glove box 26 has an opening 26a in the upper part, and is formed so as to be rotatable around a hinge pin 27 inserted in a through hole 26b formed in the lower end. A curved portion 26d that curves in a direction of closing the opening 26a is formed at the upper edge of the upright portion 26c of the glove box 26 that faces the inside of the vehicle. The surface of the panel body 11a of the instrument panel 11 is covered with a panel pad 11b. A gap 28 is formed between the curved portion 26d of the glove box 26 and the lower edge of the panel pad 11b. In this example, two outlets 23b facing the gap 28 are provided on the peripheral surface of the duct body 23a. These air outlets 23b are formed flat in the vehicle width direction, and the wind passing through the air outlets 23b is blown out from the gap 28 toward the inside of the vehicle. Further, a reinforcement 29 is installed in the vehicle width direction between the duct body 23a and the glove box 26, and a cover 32 that covers the opening 26a of the glove box 26 is attached to the reinforcement 29 via a bracket 31. Be done.

In the air-conditioner duct for a vehicle configured as described above, when the air-conditioner is used in the summer, cool air from the cooler unit 13 passes through the flow paths 13a, 14a or 13b, and the duct 21 and the side. The air is guided to the vehicle compartment through the registers 17 and 18 (FIG. 3), and at the same time, the cooled air is blown out through the gap 28 from the air outlet 23b formed in the duct body 23a. As a result, this cold wind blows out toward the abdomen or thigh of the seated occupant, so that the occupant can comfortably spend in the vehicle. Also, during heating or ventilation, warm air or fresh air outside the vehicle is blown from the outlet 23b toward the abdomen or thigh of the occupant in the same manner as described above.

In the embodiment, the glove box having the opening at the upper portion and rotatable about the hinge pin inserted at the lower end has been described, but this is an example, and the opening has the opening toward the passenger compartment. It may be a glove box having a box body and a lid that closes the opening of the box body.

[0012]

[Effect of the device]

 As described above, according to the present invention, on the peripheral surface of the duct main body located above the glove box, the air blown in the gap between the upper edge of the glove box and the lower edge of the instrument panel facing the upper edge. Since the outlet is formed, the temperature-controlled air is blown toward the abdomen or thigh of the seated occupant. As a result, the interior of the vehicle can be kept in a comfortable air-conditioning state during heating, ventilation and cooling. In addition, the airflow in the vicinity of the seated occupant increases without adjusting the wind direction, so the ventilation performance inside the vehicle can be improved.
