Description

Air conditioner for vehicle

Technical Field

Embodiments relate to an air conditioner for a vehicle. More particularly, the present invention relates to a vehicle air conditioner in which the ease of assembly of a door and access to a/S are improved by a split air conditioner case.

Background

An automobile is provided with an air conditioner for adjusting the temperature of indoor air and ventilating the air. In addition, the air conditioner for a vehicle generates hot air in winter, keeps the vehicle interior warm, generates cool air in summer, and keeps the vehicle interior cool.

The air conditioner for a vehicle may be divided into a three-piece type (THREE PIECE TYPE) in which a blower unit, an evaporator unit, and a heater core unit are separately provided, a Semi-center type (Semi-CENTER TYPE) in which the evaporator unit and the heater core unit are built in an air conditioning case, and a center-mounted type (Center Mounting Type) in which the blower unit, the evaporator unit, and the heater core unit are separately provided.

Fig. 1 is a schematic view of a conventional air conditioner for a vehicle.

Referring to fig. 1, a conventional vehicle air conditioner may include an air conditioning unit that adjusts a temperature of air by heat exchange between the air and a heat exchange medium, and a blower unit (not shown) that supplies air to the air conditioning unit.

The air conditioning unit may include an air conditioning case 10, and an evaporator 2 and a heater 3 which are sequentially provided at regular intervals along an air flow direction formed in the air conditioning case 10, wherein the air conditioning case 10 is formed with an air inlet 11 on an inlet side, and a defrost vent 12, a face vent 13, and a floor vent each of which has an opening degree adjusted by a mode door are formed on an outlet side.

In this case, the floor vent may be formed in the air conditioning case 10 by being divided into the front seat floor vent 14 and the rear seat floor vent 15. For the left and right air-conditioning on the driver's seat side and the passenger's seat side, the floor vent 14 and the rear seat floor vent 15 may be provided in two on the left and right sides, respectively. Thereby, two floor flow paths can be formed in the air conditioning case 10.

Accordingly, the blower unit of the vehicle air conditioner may supply air into the air conditioning case 10 through the air inlet 11, and the air flowing into the air conditioning case 10 may be discharged through the defrost vent 12, the face vent 13, and the floor vent. Wherein the temperature of the air flowing into the air conditioning case 10 can be adjusted by the evaporator 2 and the heater 3.

On the other hand, the air conditioning case 10 of the above-described air conditioning unit is formed as a single piece, so that there are problems of assembly of the parts and approaching lowering for a/S.

Further, since the air conditioning case 10 is formed as a single piece, the cover 20 needs to be coupled to one of the outer surfaces of the air conditioning case 10 in the vehicle indoor side direction in order to form the center flow path CH connected to the console box (not shown). This causes a problem that the size of the air conditioning unit is increased in the front-rear direction of the vehicle body. One side of the center flow path CH may be connected to the console box provided for supplying air after air conditioning to the rear seat space, and the other side may be connected to the hole 16 formed in the air conditioning case 10.

For this reason, there is a need for a vehicle air conditioner that is structurally improved in terms of improving the assemblability and ensuring access to a/S and securing the indoor space of the vehicle.

Fig. 2 is a perspective view showing an air conditioner for a vehicle according to an embodiment, and fig. 3 is a split perspective view showing the air conditioner for a vehicle according to an embodiment.

In fig. 2 and 3, the x-direction may be the vehicle body front-rear direction and the y-direction may be the vehicle width direction with respect to the vehicle. The z direction may be an up-down direction or a vertical direction. In addition, the x-direction, the y-direction, and the z-direction may be perpendicular to each other.

The front-rear direction may include an indoor direction (rear) which is a direction toward the indoor side of the vehicle and an engine room direction (front) which is an opposite direction to the indoor direction. The door shaft is inserted into the air conditioning case along the vehicle width direction, and therefore the vehicle width direction may be referred to as an axial direction or an insertion direction. In addition, the virtual line C shown in fig. 3 may represent the axial center of the above-described axis.

Referring to fig. 2 and 3, the air conditioning device 1 for a vehicle according to the embodiment may include an air conditioning case 100 in which a heat exchanger is disposed, a cover 200 coupled to the air conditioning case 100 so as to form a central flow path CH, and a door 300 coupled to the air conditioning case 100 so as to adjust an amount of air moving to the central flow path CH. Since one side of the center channel CH may be connected to the console box, the center channel CH may be also referred to as a console channel.

The air conditioning case 100 may include a first air conditioning case 400, a second air conditioning case 500 disposed apart from the first air conditioning case 400 in the vehicle width direction, and an intermediate case 600 disposed between the first air conditioning case 400 and the second air conditioning case 500. The intermediate case 600 may be detachably coupled with the cover 200. At this time, the first air-conditioning case 400 may be referred to as a left-side air-conditioning case, and the second air-conditioning case 500 may be referred to as a right-side air-conditioning case.

Accordingly, the air-conditioning case 100 may be formed by detachably coupling the first air-conditioning case 400, the second air-conditioning case 500, and the intermediate case 600, which are divided into three. The cover 200 and the door 300 may be detachably coupled to the air conditioning case 100. Thus, the split structure of the vehicle air conditioner 1 can improve ease of assembly of the heat exchanger, the cover 200, the door 300, and the like disposed inside and access for a/S.

The air conditioning case 100 and the cover 200 may form the outer shape of the vehicle air conditioning apparatus 1. In addition, a heat exchanger may be disposed inside the air conditioning case 100. Wherein the heat exchanger exchanges heat with air flowing inside the air-conditioning case 100, so that the temperature of the air can be adjusted. In this case, the heat exchanger may be the evaporator 2 and the heater 3. The heater 3 may be a PTC heater (Positive Temperature Coefficient Heater: positive temperature coefficient heater).

Referring to fig. 2, the air conditioning case 100 of the vehicle air conditioning apparatus 1 may include a plurality of ventilation openings formed to blow air into the vehicle interior and a plurality of air passage portions formed to flow air into the ventilation openings. Among them, the plurality of ventilation openings may function as a discharge opening for discharging air inside the air-conditioning case 100.

The air conditioning case 100 may include a temperature adjustment door (not shown) disposed corresponding to the ventilation openings to adjust the amount of air discharged through each ventilation opening.

Therefore, the vehicle air conditioner 1 can realize a plurality of air conditioning modes, and the temperature in the vehicle room can be adjusted by using the plurality of ventilation openings and the temperature adjusting door.

The plurality of ventilation openings are formed to communicate the inside and the outside of the air-conditioning case 100, and may include a defrost vent 110 formed to spray air toward the front glass side of the vehicle, a face vent 120 formed to spray air toward the face side of the front seat passenger, and a floor vent 130 formed to spray air toward the foot side of the passenger.

The floor vent 130 may include a left vent 130a configured to discharge air to a left side (a driver's seat) in the vehicle interior and a right vent 130b configured to discharge air to a right side (a passenger's seat) in the vehicle interior. Wherein the left side vent 130a may be referred to as a first floor vent and the right side vent 130b may be referred to as a second floor vent.

The left vent 130a and the right vent 130b may be disposed at predetermined intervals in the vehicle width direction. For example, the left and right vents 130a and 130b may be symmetrically disposed on both sides of the air conditioning case 100 with respect to the vehicle width direction. Thus, the left vent 130a and the right vent 130b may be arranged on virtual lines arranged in the vehicle width direction.

Fig. 4 is a split perspective view showing an air conditioning case of the air conditioning device for a vehicle according to the embodiment, fig. 5 is a partial enlarged view of an intermediate case of the air conditioning device for a vehicle according to the embodiment, fig. 6 is an enlarged view showing a door coupled to an intermediate case insertion manner of the air conditioning device for a vehicle according to the embodiment, fig. 7 is an enlarged view showing an operation of the door coupled to the intermediate case of the air conditioning device for a vehicle according to the embodiment, and fig. 8 is an enlarged view showing a coupling of the intermediate case, the door, and the second air conditioning case of the air conditioning device for a vehicle according to the embodiment.

The above-described coupling process of the air-conditioning case 100 and the door 300 is described with reference to fig. 2 to 8, and after the first air-conditioning case 400 is coupled to the intermediate case 600, the door 300 is insertedly coupled to the intermediate case 600. Further, by coupling the second air conditioning case 500 to the intermediate case 600, the door 300 may be rotatably disposed in the air conditioning case 100.

That is, in the process of coupling the respective components of the air-conditioning case 100 divided into three, the door 300 is coupled in the axial direction, so that the assembling property of the door 300 of the air-conditioning case 100 can be improved. In this case, the door 300 includes a plate 320 protruding from the shaft 310 in a radial direction, and thus the door 300 can be easily assembled to the intermediate case 600 by using an opening 621 formed in the support 620 of the intermediate case 600. In addition, the split structure of the air conditioning case 100 can improve ease of arrangement of the heat exchanger or the like arranged inside and access for a/S.

Referring to fig. 4, the first air-conditioning case 400, the intermediate case 600, and the second air-conditioning case 500 implementing the air-conditioning case 100 may be arranged in the vehicle width direction. For example, the first air-conditioning case 400 and the second air-conditioning case 500 may be arranged in the vehicle width direction, and the intermediate case 600 may be arranged between the first air-conditioning case 400 and the second air-conditioning case 500, thereby forming the air-conditioning case 100. Wherein, the first air-conditioning case 400 may be referred to as a left-side air-conditioning case, and the second air-conditioning case 500 may be referred to as a right-side air-conditioning case.

The first air-conditioning case 400 and the second air-conditioning case 500 may be detachably coupled to the left and right sides of the middle case 600, respectively. The air inlet 11 may be formed in any one of the first air conditioning case 400 and the second air conditioning case 500.

The first air conditioning case 400 may be formed with a left ventilation opening 130a. The second air conditioning case 500 may be formed with a right vent 130b.

The first air-conditioning case 400 and the second air-conditioning case 500 may include grooves (not shown) for disposing the ends of the shaft 310, respectively. Thus, the groove prevents the door 300 from moving beyond the rotation of the groove, and the door 300 can be assembled. The movement may be referred to as play, and may be axial movement or radial movement with respect to the shaft 310.

The intermediate case 600 may include a cavity recessed toward the engine room so as to form the central flow path CH. Thus, the intermediate case 600 may include an opening formed to be opened in the indoor direction. At this time, the cover 200 is disposed to cover the opening, so that a central flow path CH may be formed together with the intermediate case 600.

For example, the intermediate case 600 may include a groove structure H recessed in the engine room direction, and an end portion of the outer cover 200 may be disposed on the indoor direction side of the groove structure H, thereby forming the central flow channel CH. The groove structure H is a part of the central channel CH, and thus may be referred to as a channel structure.

Referring to fig. 4 and 5, the intermediate case 600 may include a main body 610 formed with a hole 611 and a supporting part 620 formed at the main body 610 to rotatably support the shaft 310 of the door 300.

The main body 610 may be formed in a shape including a groove structure H recessed toward the engine room. For example, the body 610 may be formed to have a "ᄃ" cross-section. In this case, the main body 610 may be formed to be bent in at least one region in view of the shape of the central channel CH, etc.

The main body 610 may have a hole 611 penetrating one surface of the main body 610 to allow air, the temperature of which is adjusted by the heat exchanger, to flow into the central flow path CH. Thus, any one of the air passage portions formed in the air conditioning case 100 and the central flow path CH can communicate with each other through the hole 611.

Here, one surface of the body 610 in which the hole 611 is formed may be an inner surface. Accordingly, the intermediate case 600 may have the channel structure formed by an inner surface and a side wall portion protruding from the inner surface.

The support 620 may be formed on the main body 610 so as to rotatably support the shaft 310.

The supporting part 620 may be formed by bending a part of the region of the body 610. Alternatively, the supporting part 620 may be formed in a pipe shape and may be formed in a shape in which a region is cut. Thus, the support 620 includes an area cut in the axial direction, and the cut area may be an opening 621. For example, a part of the region in the supporting portion 620 may be formed to have a "C" -shaped cross section.

Accordingly, the support portion 620 may include an opening 621 provided for axial movement of the plate 320 of the door 300, and a curved surface 622 formed to support the outer circumferential surface of the shaft 310.

The curved surface 622 may rotatably support an outer circumferential surface of the shaft 310. At this time, the curved surface 622 may be disposed to contact a partial region of the outer circumferential surface of the shaft 310. For example, the curved surface 622 may be formed to have a "C" shape or a circular arc shape in cross section.

On the other hand, the supporting part 620 may be formed at a pair of the bodies 610 so as to be separated in the axial direction. As a result, the pair of support portions 620 support the outer peripheral surfaces of the shafts 310, respectively, and radial play such as swinging of the door 300 can be prevented.

Referring to fig. 5 and 6, the supporting part 620 may include a first supporting part 620a disposed at the first air conditioning case 400 side and a second supporting part 620b disposed at the second air conditioning case 500 side. The first support portion 620a and the second support portion 620b may be disposed apart from each other in the vehicle width direction.

The first support part 620a may support one side of the shaft 310 and may include a first through hole 620a-1 through which the shaft 310 is disposed. Thus, the shaft 310 inserted in the vehicle width direction may be disposed in the intermediate case 600 after penetrating the first through hole 620a-1. The first through hole 620a-1 may be referred to as a left through hole.

The second support part 620b supports the other side of the shaft 310 and may include a second through hole 620b-1 and an opening 621, which are disposed to pass through the shaft 310. The opening 621 is arranged in the radial direction of the second through hole 620b-1, and may be formed to communicate with the second through hole 620 b-1. The second through hole 620b-1 may be referred to as a right through hole.

Thus, the shaft 310 may be inserted into the vehicle width direction and pass through the second through hole 620b-1 and then pass through the first through hole 620a-1, thereby being disposed in the intermediate case 600. At this time, the plate 320 of the door 300 may pass through the opening 621 formed in the second supporting part 620 b. That is, the opening 621 is disposed in a movement path in which the plate 320 moves, so that the opening 621 can function as a movement path for moving the plate 320.

In addition, the first supporting part 620a, in which the opening 621 is not formed, may function as a stopper when the door 300 is inserted.

In the air conditioning case 100, there is a possibility that air flowing along the central flow path CH flows out through the opening 621.

Accordingly, as shown in fig. 8, the protrusion 510 of the second air conditioning case 500 may be coupled to the opening 621 formed in the second supporting part 620 b. Thereby, the protrusion 510 can prevent the air flowing along the central flow path CH from flowing out through the opening 621.

That is, the air conditioning case 100 can ensure the assembling property of the door 300 and the sealing property of the central passage CH by using the opening 621 formed for assembling the door 300 inserted and coupled in the axial direction and the protrusion 510 of the second air conditioning case 500 coupled to the opening 621. In detail, the intermediate case 600 includes the opening 621 formed for assembling the door 300 inserted and coupled in the axial direction, and the second air conditioning case 500 is provided with the protrusion 510 coupled to the opening 621, so that the assembling property of the door 300 and the sealing property of the central flow path CH can be ensured.

The cover 200 is detachably coupled to the intermediate case 600, thereby forming the central passage CH. In this case, the end portion of the cover 200 may be disposed to overlap the first air-conditioning case 400 and the second air-conditioning case 500 in the vehicle width direction. This can reduce the size of the vehicle air conditioner 1 in the front-rear direction.

The center flow path CH may be provided with a left flow path and a right flow path on both sides thereof with respect to the vehicle width direction. In addition, the center channel CH may be disposed separately from the left and right channels by the intermediate case 600. Thus, only the air flowing in through the hole 611 flows through the central flow channel CH. The left side flow path may be a left side floor flow path, and the right side flow path may be a right side floor flow path. The left side flow path and the right side flow path may be the air passage portion disposed in the air conditioning case 100.

On the other hand, the left flow path may be formed by the combination of the first air conditioning case 400 and the middle case 600. In addition, the right side flow may be formed by coupling the second air conditioning case 500 and the middle case 600.

In addition, the left side vent 130a may be configured to communicate with the left side flow path, and the right side vent 130b may be configured to communicate with the right side flow path. As a result, a portion of the lower portion side of the center flow channel CH may be disposed so as to overlap the left vent 130a and the right vent 130b with respect to the vehicle width direction.

Referring to fig. 4, the door 300 may include a shaft 310 rotatably disposed in the intermediate housing 600 and a plate 320 radially protruding from an outer circumferential surface of the shaft 310. Wherein the shaft 310 and the plate 320 may be integrally formed.

The shaft 310 may be formed in a cylindrical shape or a tubular shape. Further, the rotation may be performed by an actuator (not shown) such as a motor or the like and a power transmission means. Among them, an arm, a cam, a lever, or the like can be used as the power transmission means.

The plate 320 may be formed in a plate shape, and may be disposed to be long in the axial direction.

In addition, as the shaft 310 rotates, the plate 320 may open and close the hole 611.

On the other hand, the door 300 may further include a glue spreading portion disposed along an edge of the plate 320. The glue-applied portion may be formed of a material such as rubber, and the sealing property may be improved when the hole 611 is closed. In this case, the adhesive-coated portion may be integrally injection-molded with the plate 320.

While the present invention has been described with reference to the embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention as set forth in the following claims. In addition, the distinguishing features related to these modifications and alterations should be interpreted as being included in the scope of protection of the present invention as defined in the claims.
