An automatic air conditioner mounted on a vehicle generally has a temperature sensor (internal temperature sensor) for detecting the temperature in the vehicle compartment, and the internal temperature sensor is provided on, for example, an instrument panel in the vehicle compartment. It is arranged at the air intake port. The air suction port is connected by an aspirator hose to an aspirator attached to a side surface of a case of an air conditioner unit provided in the instrument panel. The aspirator is designed so that the conditioned air leaks slightly from the air passage of the air conditioner unit. The negative pressure generated by this conditioned air flowing through the air passage inside the aspirator causes the cabin to enter the aspirator hose from the air intake port. Air is taken in. In this way, the air inside the vehicle flows around the inside air temperature sensor, so that the inside air temperature sensor can detect the inside air temperature.
[0003]
However, when the temperature inside the vehicle is detected by the internal air temperature sensor provided at the air intake port provided on the instrument panel, the influence of heat generated from peripheral devices such as audio equipment, meters, and navigation equipment As shown in FIG. 5, it has been proposed to arrange an internal temperature sensor or a humidity sensor 93 in the middle of the aspirator hose 90, that is, at an intermediate point between the aspirator 91 and the air inlet 92, as shown in FIG. (For example, refer to Patent Document 1).

BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is an exploded perspective view showing a configuration of an aspirator hose 1 for a vehicle air conditioner according to an embodiment of the present invention. The aspirator hose 1 is composed of a first hose 2 and a second hose 3, and a sensor (internal temperature sensor) for detecting the temperature of vehicle interior air can be accommodated as a connecting means 6 between these hoses 2 and 3. A sensor housing 4 and an attachment 5 that can be detachably connected to the sensor housing 4 are provided. The first hose 2, the second hose 3, the sensor housing 4, and the attachment 5 are all made of synthetic resin.
[0013]
FIG. 2 shows an aspirator hose 1 arranged so as to connect a vehicle interior air intake port 81 provided in an instrument panel 80 and an aspirator 60 attached to an air conditioner unit in a vehicle. The first end 21 of the first hose 2 is connected to an aspirator 60 provided on the side of the case 70 of the air conditioner unit in the instrument panel 80, and the second end 22 of the first hose 2 is connected to the sensor housing 4. Is attached. The sensor housing 4 has a substantially rectangular parallelepiped main body, and has an air passage 43 formed therein. A sensor mounting portion 44 is formed in the air passage 43, and an internal air temperature sensor 45 is provided in the sensor mounting portion 44 so as to be exposed to the air passage 43. The inside air sensor 45 uses, for example, a thermistor element and utilizes the physical properties of a thermistor whose resistance changes with temperature.
[0014]
The vehicle interior air inlet 81 is formed at the center of the instrument panel 80, for example, near the upper side of an audio device or the like so as to open into the vehicle interior. A first end 31 of the second hose 3 is connected to an air intake 81 in the vehicle compartment, and an attachment 5 is attached to the second end 32. The attachment 5 has an air passage 53 formed therein.
[0015]
FIG. 3 is an enlarged view showing a cross section of the connecting means 6 for connecting between the first hose 2 and the second hose 3. The sensor housing 4 has a cylindrical connecting portion that can be connected to the first hose 2 at a first end 41 thereof. By connecting this connecting portion to the second end 22 of the first hose 2, the sensor housing 4 is connected to the first hose 2 so that the air passage 43 inside the sensor housing 4 is connected to the air passage inside the first hose 2. Can be linked.
[0016]
Attachment 5 has a cylindrical connecting portion at the first end 51 that can be connected to second hose 3. By connecting this connection portion to the second end 32 of the second hose, the attachment 5 can be connected to the second hose 3 so that the air passage inside the attachment 5 is connected to the air passage inside the second hose 3. it can.
[0017]
A second end 52 of the attachment 5 can be detachably connected to a second end 42 of the sensor housing 4. When these are connected, the air passage in the attachment 5 and the air passage in the sensor housing 4 are connected, and as a result, the air passage of the first hose 2 and the air passage of the second hose 3 are communicated.
[0018]
By connecting the aspirator 60 and the vehicle interior air intake 81 with such an aspirator hose 1, an air passage connecting the air passage in the aspirator 60 and the vehicle interior air intake 81 can be formed.
[0019]
The aspirator 60 is attached to the case 70 of the air conditioner unit so as to communicate with an air passage formed in the air conditioner unit, for example, at a position between a heater core and a foot opening (not shown). The conditioned air slightly leaks from the air passage inside the air conditioner unit to the aspirator 60, and the leaked conditioned air flows through the aspirator 60, so that a negative pressure is generated in the aspirator 60. It is taken into the aspirator hose 1 from the vehicle interior air suction port 81. The taken-in vehicle air passes through the air passages of the second hose 3, the attachment 5, the sensor housing 4, and the first hose 2 from the vehicle interior air intake 81, reaches the aspirator 60, and is conditioned air leaked from the air conditioner unit. At the same time, the air is blown into the vehicle compartment from an air outlet (not shown) of an aspirator 60 provided in an instrument panel or the like. The inside air temperature sensor 45 in the sensor housing 4 detects the temperature of the air in the vehicle interior flowing through the aspirator hose 1 in this manner, thereby obtaining an average vehicle interior temperature.
[0020]
According to the configuration of the present embodiment, by appropriately adjusting the lengths of the first hose 2 and the second hose 3, the internal air temperature sensor 45 is arranged at an arbitrary position between the aspirator 60 and the vehicle interior air intake 81. It is possible to set up. Therefore, only by changing the lengths of the first hose 2 and the second hose 3, the position of the internal air temperature sensor 45 can be easily changed, for example, so as to avoid the influence of heat from peripheral devices. Further, in the present embodiment, by using the attachment 5 capable of connecting between the sensor housing 4 and the second hose 3, the sensor housing conventionally used for attaching the inside air temperature sensor to the vehicle interior air intake port is directly used. It can be used as the sensor housing 4 in the present embodiment.
