Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle air conditioner used for personal cooling and heating in a passenger compartment, for example.

[0002]

2. Description of the Related Art Conventionally, in this type of automobile air conditioner, a plurality of air outlets are provided in a seat surface portion and a backrest surface portion of a seat, as disclosed in, for example, Japanese Utility Model Publication No. 53-52254. Some have a configuration in which temperature-controlled air is discharged from these air outlets.

[0003]

However, in such an air conditioner for a vehicle having a conventional structure, as a temperature control mechanism for discharging temperature controlled air from the air outlet, an air conditioner mounted on a vehicle body is used. Since the blower blower is used as a blower for guiding the cool air and the hot air to the seat side through the duct, there is a problem that the entire temperature control mechanism becomes large and restricts the degree of freedom in vehicle body design. It was

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an automobile air conditioner in which the temperature control mechanism can be downsized and the degree of freedom in vehicle body design can be increased.

[0005]

In order to solve the above-mentioned problems, the present invention provides a seat mounted on the floor of a vehicle body with a large number of air outlets, and from these air outlets to the lower part of the seat. In an air conditioner for a vehicle that discharges temperature-controlled air through a temperature-control mechanism installed in the vehicle, the temperature-control mechanism exposes one fin from the floor of the vehicle body to the outside of the vehicle and the other fin to the inside of the vehicle. The thermo module facing the thermo module and the duct for guiding the air whose temperature is controlled by the other fin of the thermo module to the air outlet of the seat are provided.

[0006]

That is, according to the present invention, the temperature control mechanism is constituted by a thermo module in which one fin is exposed from the floor surface of the vehicle body to the outside of the vehicle and the other fin is exposed to the inside of the vehicle. Since the air whose temperature has been adjusted by the fins is guided to the air outlet of the seat through the duct, a blower blower is not required, and the temperature adjustment mechanism can be downsized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described in detail with reference to the drawings. As shown in FIG.

On the floor surface 1 of the vehicle body, a support frame 2,
A seat 3 is placed via the seat 2, and the seat 3 is composed of a seat portion 4 and a backrest portion 5. The backrest portion 5 can be tilted in the front-rear direction via a reclining shaft 6. ing.

An air passage 7 reaching the seat portion 4 and the backrest portion 5 is formed in the seat 3.

In the air passage 7, a large number of air outlets 41 and 5 are opened in the seat surface portion 4a of the seat portion 4 and the backrest surface portion 5a of the backrest portion 5, respectively.
1 communicates with each other, and cool air or warm air blown from a temperature adjusting mechanism 20 described later is discharged from these air outlets 41 and 51.

Reference numeral 8 in the drawing denotes a slide rail slidably provided on the support frames 2 and 2, and the seat 3 is mounted via the slide rail 8 so as to be slidable in the front-rear direction.

The slide rail 8 is shown in FIGS.
As shown in FIG. 3, a connecting pipe 9 connected to a communication port 7a communicating with an air passage 7 opened at the lower part of the seat portion 4 of the seat 3 is provided, and the connecting pipe 9 is provided at the lower part of the gutter. It has a configuration in which it faces the inside of the connector 10.

The connector 10 is fixed to the floor surface 1 side of the vehicle body, has a width corresponding to the sliding amount of the seat 3, and always connects the connecting pipe 9 according to the sliding amount of the seat 3. Faces inside the connector 10.

Therefore, even if the seat 3 is slid back and forth, air such as cold air or hot air discharged from the temperature adjusting mechanism 20 described later discharged from the connector 10 is always supplied to the connecting pipe 9. It is supposed to be guided.

Further, reference numeral 11 in the drawing denotes a duct connected to the connector 10, and this duct 11 has a temperature adjusting mechanism 2 which will be described later.
It is connected to 0.

However, the temperature control mechanism 20 described above is not shown in FIG.
Further, as shown in FIG. 5, the thermo module 23, 23 is arranged in the housing 21 installed on the floor surface 1 of the vehicle body so as to be divided into upper and lower parts via a heat insulating material 22, and the thermo module 23, The heat radiation fins 24 provided on the lower part of the vehicle 23 are exposed from the floor surface 1 of the vehicle body to the outside of the vehicle, and the heat exchange fins 25 provided on the upper part of the vehicle are exposed to the inside of the vehicle.

That is, in the temperature control mechanism 20, the outside air during running travels to the upper and lower portions of the front thermomodules 23, 23 from the upper and lower openings 21a, 21b opened in the shape of a trumpet in front of the vehicle body of the housing 21. The heat radiation fins 24 and the heat exchange fins 25 provided are introduced toward the side.

Then, the thermo modules 23, 23
From the upper side of the heat exchanger 2 through the air filter 26
The outside air introduced into the No. 5 side is temperature-controlled by the heat exchange fins 25, and the temperature-controlled air is guided to the connector 10 via the duct 11.

Further, the temperature-controlled air led to the connector 10 is led to the air passage 7 in the seat 3 through the connecting pipe 9, and as shown in FIG. 1, the seat surface portion 4a of the seat 3 is formed.
And a large number of air outlets 41 and 51 opened in the backrest surface portion 5a, respectively.

On the other hand, the outside air after the heat exchange introduced to the lower radiating fins 24 side of the thermo modules 23, 23 is
The gas is discharged from a discharge port 27 that is open to the rear of the housing 21.

[0021]

As is apparent from the above description, the present invention provides a temperature control mechanism for a thermo module in which one fin faces the outside of the vehicle from the floor of the vehicle body and the other fin faces the inside of the vehicle. Since it is configured to guide the air whose temperature is regulated by the other fin of this thermo module to the air outlet of the seat through the duct, in order to eliminate the need for a conventional blower, It is possible to reduce the size of the temperature control mechanism as a whole, thereby increasing the degree of freedom in designing the vehicle body.
