Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an air conditioning system for an automobile.

(Prior Art) As a conventional automobile air conditioning system, there is a well-known technology as shown in FIG. 3, for example. That is, the air conditioning system 1
The vehicle humidifier 2 and the air conditioning unit 3 are arranged side by side. The humidifier 2 uses water 4 supplied from a tank (not shown).
1 has a vibrator 5 for atomizing the air, an air suction port 6, and a fan 7 for sucking air from the suction port 6 and diffusing and discharging the mist C. The air conditioning unit 3 is configured such that an outside air duct 10 connected to an inlet 9 of a vehicle body 8 and an inside air duct 12 opened in a vehicle interior 11 can be switched by an intake door 13, and a blower unit 14 is provided downstream of this door 13. Then, a heater core (not shown) or the like is connected downstream of the blower unit 14. Reference numeral 15 is an instrument panel, and 16 is a front wind panel.
A is outside air and B is inside air.

When the intake door 13 is in the state of the solid line, the inside air is circulated (RECIRC), and when it is in the state of the broken line, the outside air is introduced (FRESH).

(Problems to be solved by the invention) However, in the air conditioning system 1, since the humidifier 2 and the air conditioning unit 3 operate independently, the intake door 13 remains long while being RECIRC. When the humidifier 2 for an automobile is operated for a long time, there is a possibility that window fogging may occur.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an air conditioning system for an automobile in which windows are not fogged.

[Structure of the Invention] (Means for Solving Problems) According to the structure of the present invention for achieving the above object, an intake switch and a humidifier switch are connected in series, and when the intake switch is switched to the internal air circulation side. It is characterized in that electricity is not applied to the humidifier switch.

(Operation) With the above configuration, the intake switch is
On the CIRC side, the operation of the humidifier is stopped in conjunction with this, so that window fog does not occur there.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a circuit diagram of a first embodiment according to the present invention. In FIG. 1, the humidifier switch 20 of the humidifier 2 and the intake switch 21 are connected in series, and the intake switch 21 operates as follows. , It is determined whether the intake door 13 is FRESH or RECIRC, and is turned ON at the time of FRESH.

Therefore, if the intake switch 21 is not turned on, the vibrator 5 does not operate even if the humidifier switch 20 is turned on. Further, when the vibrator 5 is operating, the intake switch 21 is turned off (FRESH → RECIRC).
If this is set, the vibrator 5 is stopped. That is, since the humidifier 2 does not operate when the intake door 13 is in RECIRC state, it is possible to prevent fogging of the window.

FIG. 2 is a circuit diagram of a second embodiment according to the present invention. The intake switch 21 and the humidifier switch 2 of the first embodiment are shown in FIG.
A timer switch 22 is provided between the timer switch 22 and 0.

Therefore, even if the intake switch 21 is turned off (FRESH → RECIRC) while the vibrator 5 is operating, the vibrator 5 is operating and humidifies the vehicle interior 11 within the set time of the timer, but the set time is exceeded. Then, the current is cut off by the timer switch 22 and the vibrator 5 is stopped.

That is, the intake switch 21 is temporarily turned off.
If it is within a certain time even after (FRESH → RECIRC), the humidifier 2 continues to operate effectively without stopping. However, since the humidifier 2 does not operate for a long time, window fog does not occur.

[Advantages of the Invention] As described above, according to the present invention, the operation of the vehicle humidifier is linked with the switching of the intake door of the vehicle air conditioner, so that the vehicle humidifier can be used for a long time in a state of internal air circulation. The vessel will not operate and window fogging can be reliably prevented.
