Vehicle air conditioning device

Abstract

The present invention relates to a vehicle air conditioning device (100) capable of improving sealing ability by doubly sealing a defrost vent (112) of an air conditioning case (110), and increasing the amount of airflow discharged inside a vehicle while simultaneously preventing an increase in the amount of force needed to actuate a face door (170) and, more particularly, to a vehicle air conditioning device comprising: a ball (13); the air conditioning case (110) in which a floor vent (114) is formed; a defrost door (160) installed to be rotatable via rotation shafts respectively inside theair conditioning case (110), and opening and closing each of the vents; the face door (170); the defrost vent (112) for discharging air entering through the floor door (150) and an air inlet (111) inside the air conditioning case; and a face vent (in the passage of which an evaporator and a heater core are installed in that order), wherein the vehicle air conditioning device (100) is characterizedin that the face door (170) is configured to doubly seal the defrost vent (112).

Description

technical field [0001] The present invention relates to an air conditioner for a vehicle capable of improving sealing by doubly shielding a defrost vent of an air conditioner case, and increasing discharge to a vehicle while preventing an increase in actuation force of a mode door by air negative pressure The amount of air inside. Background technique [0002] In general, an air conditioner for a vehicle is a vehicle component installed in a vehicle to cool or heat the interior of the vehicle in summer or winter, or to defrost from the windshield in rainy or winter seasons to ensure the driver's front and rear vision. Such an air conditioner usually includes both a heating device and a cooling device, so that it can be controlled by the steps of selectively introducing indoor air or outdoor air into the air conditioner, heating or cooling the introduced air, and blowing the heated or cooled air into the vehicle. The vehicle interior is heated, cooled or ventilated. [0003...

Problems solved by technology

[0013] However, in such a conventional vehicle air conditioner 1, in the case where the mode door 16 is a flat door or a center pivot door, since the opening direction of the mode door 16 is different from the flow direction of the air passing through the vents 12a to 12d, On the contrary, the flow of air introduced into the vents 12a to 12d is thus hindered

[0014] Additionally, this results in an increase in the actuation force used to actuate the mode door 16 due to the obstruction of air flow creating a negative pressure on the plate of the mode door 16

[0015] In addition, another disadvantage of the conventional air conditioner for vehicles is that the windshield on the front side of the vehicle is damaged due to accidental air leakage from the gap between the mode door 16 and the defroster vent 12a by opening and closing the defroster vent 12a. Covered with frost, which is inconvenient to use
