るものである。[Conventional technology] Conventionally, this type of indoor/outside air switching! ! ! For example,
There is one described in Japanese Patent Application Laid-open No. 57-164806. This internal/external air switching device basically uses a dew condensation sensor to detect a cloudy condition inside the window panel, and when this condensation sensor detects the cloudy condition, it switches from an air conditioning mode that recirculates inside air to an air conditioning mode that introduces outside air. On the other hand, when the dew condensation sensor does not detect the cloudy condition, the air conditioning mode of internal air circulation is maintained.

視界を確実に確保することができる。According to such an inside/outside air switching device, when V3 dew is generated inside the window panel and it becomes cloudy, outside air is introduced into the cabin, and the condition of the air inside the cabin approaches that of outside air. It is possible to eliminate fogging of the window panel, and to ensure visibility through the window panel while driving the vehicle.

Therefore, it cannot be said that the optimal switching between inside and outside air is performed for the occupants, especially when the outside air temperature is high and the inside air temperature is high.

うになっている。In the same figure, J3 is shown, and 9 and 10 are external air i! installed at the positions shown in FIG. ti degree sensor, indoor air humidity sensor, 11 is an operation switch for specifying each air conditioning mode: outside air introduction (F RS ), inside air circulation (REC), or outside air automatic control ft (AUTO). It has an outside air introduction switch 11a, an inside air circulation switch 11b, and an automatic control switch 11c corresponding to the air conditioning mode. 20 is an outside air humidity sensor 9 and an inside air temperature sensor 10
, is a microcomputer that performs switching control I of the intake door 4 according to a flowchart 11-to be described later based on each input information from the operating switch 11. A control signal is output to the intake door actuator 5 in order to forcibly control the opening of the outside air introduction port 2 or the opening of the inside air intake port 3 by the intake door 4 in response to the air conditioning mode specified by the inside air circulation 11 switch 11b. It has become. Further, when the air conditioning mode is designated by the intransitive switch 121I of the operation switch 11, the microcomputer 20 outputs the detected G degree signal 1-4out from the outside air humidity sensor 9 and the detected humidity signal 1-4out from the inside air 9 degree sensor 10. For example, as shown in Fig. 4, when the difference △H between the inside air humidity 1-1 inch and the outside air humidity 1OLIt is greater than the predetermined humidity difference +A, outside air is introduced from the inside air circulation (RFC) (FR8).
In order to switch the air conditioning mode to The air conditioning mode is turned off and a control signal is output to perform moxibustion. The above control signals from the microcomputer 20 are transmitted to the intake door actuator 5 via the drive device 21, and the intake door actuator 5 operates according to the control signals.

に導入1Jる。The microcomputer 20 has an outside air humidity sensor and an inside air humidity sensor 10. Each signal from the operation switch 11 is read at a predetermined period. Here, when the inside air circulation switch 11b of the operation switch 11 is pressed, the intake door switching control section 20
should switch the air conditioning mode to internal air circulation (RFC) mode (output a control signal, and actuate the intake door actuator 5 based on this control signal to cause the intake door 4 to open the internal air intake port 3 (to open the external air inlet 2)
), one person switch 11 (the force circulates the air inside the vehicle. Also, outside 2), one person switch 11
When a is pressed, the microcomputer 20 outputs a control 'l+ signal to switch to the outside air 29 person (FR3) mode, and the intake door actuator 5 is operated based on this 11 control signal to open the intake door 4 to the outside air 29 person (FR3) mode. The air intake 2 is opened (the inside air intake port 3 is closed 11), and air from outside the vehicle is introduced into the vehicle interior by the operation of the pro-ar unit 1 in the same manner as described above.

The microcomputer 20 confirms the designated signal from this own IJJ tlI control switch 11c, and detects the detected inside air humidity (-1 inch) from the inside air humidity sensor 10 and the outside air humidity sensor 9.
The difference Δt() from the detected outside air GIIJ)-1out is calculated. Then, when it is determined that this humidity difference ΔH is greater than the predetermined humidity +A, the current air conditioning mode is further confirmed and the current outside air intake (FR8 > mode, the control t2n IA is output to maintain this air conditioning mode, and if the current internal air circulation (REC) mode is, outside air is introduced (FR8
) mode is output, and the intake door 4, which had closed the outside air inlet 2, is driven to open the outside air inlet 2 based on this +7J return signal.

If it is currently in the inside air circulation (REC) mode, the microcomputer 20 outputs a dust signal to maintain this air conditioning mode, and if it is currently in the outside air introduction (FR3) mode, the dust signal is output to the inside air circulation (RF C>) mode. The switching signal 11 is also output, and the intake door 4, which had closed the inside air intake port 3, is driven to open the inside air intake port 3 based on this switching υ control signal.
