Description

Wind mode controller of vehicle air conditioner {The wind mode controller of airconditioner for vehicle}

The present invention provides a heat exchanger for cooling and heating installed in a vehicle, wherein the blower case discharges the hot and cold air heat exchanged in the heat exchanger to a unified discharge port, and the discharge port is provided with a switching means according to the mode in which the switching means is set. The present invention relates to a wind direction mode control device for an air conditioner for a vehicle, which opens and closes vent outlets and foot ducts, and controls the wind direction mode during the switching operation. The heat exchanged cold and hot air was distributed to the driver's seat and the passenger seat using a plurality of vent ducts and foot ducts, and the vent ducts and the foot ducts were installed in the blower case in a dual state. Each of these binary ducts are vented and vented as the driver switches modes by hand. Foot duct and defrost, anti-fog anti-defrost (defrost) was to be done.

However, according to the related art, each of the ducts according to the wind direction modes is configured separately, and the configuration according to the wind direction mode is very complicated because the driver configures each of the configured ducts to switch the wind direction mode. And the duct simply acts as a passage through which the air passes, and the wind direction is overlapped, that is, a vent and defrost or a foot duct and a defrost and a mode in which the vent and foot duct are operated simultaneously. Switching becomes very difficult, and since the ducts according to the above modes are separately installed and must be collected at the center of them, that is, the blower case which is the air supply passage, the installation state becomes very complicated and the structure is complicated and the volume is increased. There was a problem.

The present invention has been made in view of the conventional problems as described above, the present invention is to provide a cooling, heating heat exchanger installed in a vehicle, the hot and cold air heat exchanged in the heat exchanger to the blower case to discharge the unified outlet The discharge port is provided with a switching means to open and close the discharge port of the vent duct and the foot duct according to the set mode, the switching means and to provide a wind direction mode control apparatus for a vehicle air conditioner to control the wind direction mode in the switching operation Inba, it will be described in detail based on the accompanying drawings as follows.

In order to supply the heat exchanged air from the vehicle air conditioner to the interior of the vehicle, a blower case (1) is installed and a blower (2) is installed thereon so that one side of the blower case (1) discharges the heat exchanged air according to various wind direction modes. In this case, a discharge passage 4 is formed in a spiral in the discharge portion 3 of the blower case 1, and the vent discharge portion 4 and the foot discharge portion 6 are formed in the spiral discharge passage 4; Defrost discharge portions 7 are formed respectively, and each discharge portion is provided with opening and closing openings 8 and 9 for controlling the wind direction therethrough, and these opening and closing openings 8 and 9 are provided with respective actuators 10 ( It is configured to switch the wind direction mode while operating in 11).

The actuators 10 and 11 may be configured to operate in accordance with a set mode pulse of an electronic control unit (ECU) of a vehicle, and install a link 12 to the actuator and the link 12 The opening and closing openings (8) and (9) are connected so as to open and close the respective discharge parts while rotating.

According to the present invention configured as described above, when the cold air or warm air is generated by heat exchange in the vehicle air conditioner, the blower 2 installed in the blower case 1 is operated to supply the air heat exchanged in the vehicle air conditioner to the interior of the vehicle. The heat exchanged air passes through the vent discharge unit 5 and the foot discharge unit through the discharge passage 4 formed in a spiral shape in the discharge unit 3 of the blower case 1 according to the driver's wind direction mode operation. It is to be supplied to the inside of the vehicle through the 6 and the defrost discharge part 7.

As described above, the wind direction mode supplied to the interior of the vehicle through each of the discharge parts is the opening and closing port 8 installed in each of the actuators 10 and 11 in accordance with the setting mode of the electronic control unit (ECU) of the vehicle. Each of the discharge parts is opened and closed while operating (9) separately or simultaneously, and when the vent discharge part 5 is opened to perform a venting function, only the actuator 10 is operated to open and close the opening 8. When the discharge part 5 is opened, and the opening / closing hole 9 installed in the foot discharge part 6 is closed by using the actuator 11, air is discharged only by the vent discharge part 5 to vent the action. Will be

In addition, when the air is discharged to the foot, the vent operation is stopped by closing the open vent discharging portion 5 and opening only the foot discharging portion 6 using the actuator 11 and the opening / closing opening 9. The air to the foot is discharged. At this time, the defrost discharge part 7 is selectively operated to simultaneously perform the air discharge and the defrost action to the foot.

In addition, when all the modes are to be operated, when the actuators 10 and 11 are operated to open the opening and closing ports 8 and 9 only about 1/2, all the discharge parts are opened. The vent, foot, defrost will be able to all.

In addition, the actuators (10) (11) to be able to operate in accordance with the set mode pulse of the electronic control unit (ECU) of the vehicle without permission to adjust the opening angle and the degree of the opening and closing ports (8) (9) arbitrarily. By installing a link 12 to the actuator and connecting the openings 8 and 9 to the link 12, the rotation angle of the openings can be increased even with a small operation of the actuators. will be.

In the present invention as described above, in order to supply the heat exchanged air from the heat exchanger to the interior of the vehicle, it is configured by installing a discharge mode of various modes in the one blower case (1) The mode can be switched reliably and smoothly by opening and closing with an actuator and opening and closing, and the mode can be switched reliably and smoothly. It is possible to greatly improve the heat exchange efficiency by discharging the heat-exchanged air along the helical discharge passage while installing the unit in the state to be assembled in the blower case, and greatly reduce the volume of the blower device according to the above modes. It is easy to do it and can use it more effectively It has features such as easy switching of the card.
