(11) is coupled to the solenoid for rotating) and the blower motor 13 to supply a drive signal so that the outside air flows into the duct to circulate inside the vehicle, and also set to the bet mode (also called circulation mode) The microprocessor 31 operates the intake door 11 and the blower motor 13 to block the inflow of outside air and allow the air inside the car to circulate inside the car.

When the temperature value inside the vehicle is controlled by the temperature control resistor 33 while the vehicle air conditioning system is in operation, the microprocessor 31 is connected to the indoor temperature sensor 25, the external temperature sensor 27, and the water temperature sensor 29. By receiving the output data, the cooling system including the evaporator 15 and the heater 19 and the air mix door 17 are operated to maintain a predetermined temperature value of the internal air.

Further, the mode doors 21, 49, 51 and 35 are opened and closed while the air cooled by the evaporator 15 and the warm air heated by the heater 19 are mixed to discharge the air having a predetermined temperature value. If the discharge path is selected so that the mixed air is discharged to the front (front seat) or the rear seat of the vehicle, the mixed air passes through each of the ducts 37, 39, 41, 45 and 47, which are opened paths. It is discharged to a specific space of the car.

WARM mode ") or COOL mode (including the evaporator 15, the mode in which the air cooled by the cooling system flows in, referred to as" COOL mode "hereinafter, AMD PFR (Air Mix Door Position Feedback Resistor) : This means to feed back the position voltage of different levels according to the position of the air mix door 17). The AMD motor 23 determines the current position of the air mix door 17 by the position voltage fed back. To control the rotation.

By installing the air-conditioning system as described above in the car, the indoor temperature can be kept constant regardless of the season or the ambient temperature. Also, when the humidity inside the car is low, external air flows into the room. The indoor humidity was controlled, but when the outside air was dry, there was a limit to increase the indoor humidity by introducing the outside air.

That is, when both the interior and exterior humidity values are low, it is not possible to adjust the humidity value of the room, so it is necessary to drive in a room where the humidity value is low.

The purpose of the present invention is proposed to eliminate such a problem, and when the indoor humidity is low, the vehicle converts the water circulating in the engine and the radiator into fine water particles, and then introduces it into the room to control the indoor humidity. It is to provide an indoor humidity control device.
