Description

AIR VENT FOR VEHICLE

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle air vent, and more particularly, to a vehicle air vent capable of minimizing an energy loss of air while minimizing an installation size of the air vent.

An air conditioner is provided in the vehicle for generating warm or cool air for cooling and heating to supply the air to the room or to keep the interior of the vehicle in a pleasant condition at all times regardless of the external environment.

In addition, such an air conditioner is also used for safe driving by eliminating the windshield glass and frost generated in the windshield when the outside temperature is low, such as during the rainy season or winter season.

Typically, the air conditioner comprises an inside / outside unit for sucking outside air or inside air and supplying the inside / outside unit to the air conditioning case, and an air conditioner case in which an evaporator and a heater core are sequentially installed inside to heat or cool the air, .

The air cooled or heated by the air conditioner is supplied to the inside of the vehicle via the vehicle air vent communicated with the air conditioner case, so that the inside of the vehicle is cooled and heated.

The structure of a typical vehicle air vent includes a duct housing of a certain type in which the air cooled or heated flows therein and a duct housing arranged laterally and longitudinally in front of the duct housing to adjust the direction of air discharged through the duct housing And a plurality of horizontal and vertical baffle members.

However, since each of the horizontal baffle and the vertical baffle are formed so as to intersect with each other, the overall size of the horizontal baffle and the vertical baffle are increased, and a wide installation space is required.

In addition, since the size and the length in the front-rear direction are increased, the energy of the air supplied from the air conditioner is lost, thereby deteriorating the air conditioning efficiency.

The guide member 400 may be installed in the air flow space of the wind direction adjusting members 370 and 371 and the vertical baffle 380.

The guide member 400 may be formed in a shape in which the thickness thereof becomes thinner as the distance from the direction adjusting members 370 and 371 increases. For example, the vertical cross-section may be streamline, and due to this shape, a vortex is formed in each of the upwardly flowing air or the downwardly flowing air along the surface of the guide member 400 during the flow of air, Direction control becomes possible.

In addition, a fixing member 12 protruding forward from the axially opposite connecting portion of the first shaft 110 and the second shaft 120, and a knob 11 coupled to vertically rotate the fixing member 12, . ≪ / RTI >

The knob 11 can be pivoted when the knob 11 is rotated in the vertical direction while holding the knob 11 and the knob 11 can be pivoted to the first and second shafts 110, 120 so that the second shaft 120 slides in a state of being in contact with the outer peripheral surface of the inner shaft 130 along the longitudinal direction.

Here, the outer circumferential surface of the inner shaft 130 disposed in the hollow portion of the second shaft 120 may be coupled to the outer circumferential surface of the second shaft 120 by a method such as a key groove so that rotation between the second shafts 120 may be restricted.

The operation of the vehicle air vent according to an embodiment of the present invention as described above will be described below.

FIGS. 13 to 15 show airflows that are varied by rotation of first and second airflow control members of an air vent for a vehicle according to an embodiment of the present invention.

13 shows a state in which the pair of wind direction adjusting members 370 and 371 are moved downward relative to each other by the relative movement of the first and second power transmitting members 310 and 320 while the user pivots the knob 11 upward, As shown in Fig.

That is, air supplied to the interior of the housing 20 is guided downward by the pair of wind direction adjusting members 370 and 371, and is guided along the outer surface of the guide member 400 and the inner wall of the housing 20 The air is discharged toward the upper side of the occupant of the vehicle.

In addition, since the air flow that meanders along the surface of the guide member 400 is induced, a vortex is generated, thereby enabling effective air flow direction control.

14 shows a state in which when the knob 11 is positioned at a central portion along the vertical direction in the process of rotating the knob in the opposite direction of Fig. 13 while the knob is grasped, the pair of wind direction adjusting members 370 and 371 are approximately Indicates the state of being in a horizontal state.

At this time, it is horizontally guided by a pair of wind direction adjusting members 370 and 371 supplied to the inside of the housing 20, and is discharged horizontally along the outer surface by the streamlined end face of the guide member 400. That is, the air is directly discharged toward the occupant of the vehicle.

Fig. 15 shows a state in which the user rotates further downward compared to the state of Fig. 13 in a state in which the knob is grasped.

At this time, the air supplied to the inside of the housing 20 is guided downward by the pair of the airflow control members 370 and 371, and is guided along the outer surface of the guide member 400 and the inner wall of the housing 20 The air is discharged toward the lower side of the occupant of the vehicle.

In particular, in the case of FIGS. 13 and 15, the air supplied from the air duct is vortexed by the guide member 400, and the flow velocity is increased through the space between the housing 20 and the guide member 400 Is directed upward or downward. As a result, the energy loss of the air can be minimized.

Since the wind direction adjusting members 370 and 371 and the vertical baffle 380 are not exposed to the outside from the front panel 10, the overall size can be reduced as well as the size exposed to the outside, so that a slim structure can be formed do.
