First, a schematic configuration of the vehicle air conditioner according to the present embodiment will be described with reference to the drawings. In the following description, the front, rear, left, right, up, and down directions will be used to indicate the front, rear, left, right, up, and down directions as viewed from an occupant seated on the seat. The same definition is used for the arrows appropriately shown in each drawing, and the vehicle width direction corresponds to the left-right direction.

First, an outline of the vehicle air conditioner 1 according to the present embodiment will be described. As shown in FIGS. 1 and 2, the vehicle air conditioner 1 is disposed on a ceiling portion R of the vehicle compartment I in order to make the interior of the vehicle compartment I of the vehicle C a comfortable air conditioning environment. The blower 20 and the evaporator 70 are housed inside.

吸 The air-conditioning case 10 of the vehicle air conditioner 1 is provided with an inlet 16 and an outlet 45, which communicate with the interior of the passenger compartment I, respectively. Therefore, the vehicle air conditioner 1 sucks the air in the passenger compartment I from the suction port 16 into the air conditioning case 10 by the operation of the blower 20, and outputs the air as the blown air F whose temperature has been adjusted by the evaporator 70 to the outlet port 45. From the vehicle compartment I.

As shown in FIG. 2, the vehicle air conditioner 1 according to the present embodiment is mounted on a so-called minivan-type vehicle C having three rows of seats. In the compartment I of the vehicle C, a first-row seat Sa, a second-row seat Sb, and a third-row seat Sc are arranged in this order from the front to the rear of the vehicle.

In the vehicle C, the first-row seat Sa is configured as a driver's seat and a passenger seat. The second-row seat Sb and the third-row seat Sc are, for example, bench-type seats on which a plurality of occupants can sit.

The third-row seat Sc is arranged closer to the center in the vehicle width direction than the second-row seat Sb in relation to the layout space for the rear wheels of the vehicle C. For this reason, it arrange | positions so that the seating position of the 3rd row seat Sc may be located between the sitting positions in the 2nd row seat Sb regarding a vehicle left-right direction.

As shown in FIG. 2, the vehicle air conditioner 1 is disposed on the ceiling R of the passenger compartment I, behind the first-row seat Sa and in front of the second-row seat Sb, and at the center in the vehicle width direction. positioned. The vehicle air conditioner 1 operates according to an operation of an operation panel arranged near the second-row seat Sb and the third-row seat Sc to air-condition the second-row seat Sb and the third-row seat Sc in the passenger compartment I. It is configured to perform.

The vehicle air conditioner 1 is mainly operated by the occupant P seated on the second-row seat Sb and the third-row seat Sc, and is used to improve the comfort of the occupant P behind the passenger compartment I. In other words, the occupants of the second-row seat Sb and the third-row seat Sc can perform the air-conditioning operation of the vehicle air conditioner 1 without passing through the occupant P in the driver's seat or the passenger seat.

Next, a specific configuration of the vehicle air conditioner 1 according to the present embodiment will be described in detail with reference to FIGS. FIG. 1 shows a top view of the vehicle air conditioner 1, and FIG. 3 shows a front view of the vehicle air conditioner 1. FIG. 4 is a side view of the vehicle air conditioner 1, and FIG. 5 is a bottom view of the vehicle air conditioner 1.

As described above, the air conditioner 1 for a vehicle accommodates the blower 20 and the evaporator 70 constituting a part of a vapor compression refrigeration cycle inside the air conditioning case 10 arranged on the ceiling R of the vehicle C. It is configured.

As shown in FIGS. 1 and 3 to 5, the air-conditioning case 10 forms an upper case 11 constituting an upper outer shell of the vehicle air conditioner 1 and a lower outer shell of the vehicle air conditioner 1. The lower case 13 is provided. The upper case 11 and the lower case 13 are assembled with screws or the like.

A plurality of upper fixing portions 12 are formed symmetrically in the upper case 11. The upper fixing portion 12 is used when fixing the air-conditioning case 10 to an upper body member on the ceiling R of the vehicle C.

ファン As shown in FIG. 1 and the like, a fan housing portion 15 is arranged at the center of the air conditioning case 10 in the vehicle width direction. The fan accommodating portion 15 forms a portion on the vehicle rear side of the air conditioning case 10 and accommodates the blower 20 therein. As shown in FIG. 5, a suction port 16 is formed on the lower surface of the fan accommodating portion 15, and communicates the interior of the air conditioning case 10 and the fan accommodating portion 15 with the interior of the vehicle compartment I.

The blower 20 is disposed inside the fan housing 15 so as to face the suction port 16, sucks the air in the passenger compartment I from the suction port 16, and blows the blown air F into the air conditioning case 10.

The blower 20 is disposed inside the fan housing 15 by being fixed to a vehicle body member (for example, roof reinforcement) at the ceiling R. The blower 20 is an electric blower that drives a centrifugal multi-blade fan (that is, a sirocco fan) with an electric motor 21. The centrifugal multi-blade fan has a substantially cylindrical shape, and has a large number of blades radially outward.

3) As shown in FIGS. 3 to 5, the electric motor 21 forms a lower portion of the blower 20, and has a drive shaft extending along the vehicle up-down direction. The centrifugal multiblade fan is fixed to the drive shaft of the electric motor 21.

Therefore, by operating the electric motor 21, the blower 20 can blow the air sucked into the axial core of the centrifugal multi-blade fan through the suction port 16 to the outside in the radial direction. The rotation speed (blowing amount) of the centrifugal multi-blade fan in the blower 20 is controlled by a control voltage output from an air conditioning control device (not shown).

等 As shown in FIG. 1 and the like, an air vent 25 is formed on the front side of the vehicle in the fan housing 15. The blower port 25 is a portion blown out of the fan housing 15 when the air sucked from the suction port 16 is blown as blown air F by the operation of the blower 20. The blowing port 25 is a part for supplying the blowing air F flowing in the air conditioning case 10.

The vehicle air conditioner 1 has a first air passage 30, a second air passage 35, and a third air passage 40 in addition to the fan housing 15. Each of the first air passage 30, the second air passage 35, and the third air passage 40 is a flow path of the blown air F blown through the blower opening 25.

The first air passage 30 is formed inside the air-conditioning case 10 of the vehicle air conditioner 1 so as to extend from the air outlet 25 formed in the fan housing 15 to the front side of the vehicle. Therefore, the blown air F blown from the blower port 25 flows inside the first air passage 30 to the vehicle front side.

リブ A rib 31 is arranged on the vehicle front side inside the air conditioning case 10. As shown in FIGS. 6, 7 and the like, the upper end of the rib 31 is located at a position away from the inner surface of the air conditioning case 10 on the upper side of the vehicle by a predetermined distance, and extends in the left-right direction of the vehicle.

Therefore, the blown air F flowing through the first air passage 30 passes above the rib 31 inside the air conditioning case 10. That is, the first air passage 30 according to the present embodiment can be defined as an air passage extending from the air outlet 25 of the fan housing 15 to the rib 31 toward the front of the vehicle.

As shown in FIG. 1 and the like, the vehicle air conditioner 1 has an evaporator 70 inside the first air passage 30 in the air conditioning case 10. The evaporator 70 is connected to a vapor compression refrigeration cycle via a refrigerant pipe connection part 71, and has a tube 72 through which the refrigerant flows, and a plurality of plate fins 73 joined to the tube 72. .

Although not shown, the vapor compression type refrigeration cycle includes a compressor, a condenser, and a decompression unit (for example, an expansion valve or a capillary tube) in addition to the evaporator 70. They are connected by refrigerant piping. Accordingly, in the refrigerating cycle, the refrigerant compresses the refrigerant to a high-temperature and high-pressure state and releases heat in the condenser. Then, the refrigerant is depressurized by the decompression unit and flows into the evaporator 70.

Accordingly, the evaporator 70 can be cooled by absorbing heat from the blown air F by heat exchange between the blown air F flowing through the first air passage 30 and the refrigerant flowing through the tube 72. That is, the evaporator 70 is a cooling heat exchanger in the vehicle air conditioner 1, and corresponds to the heat exchanger in the present disclosure.

The tube 72 in the evaporator 70 connects the ends of a plurality of straight pipe portions extending linearly so as to cross the first air passage 30 in the vehicle width direction with a U-shaped pipe having a substantially U-shape. It is configured. Therefore, the tube 72 is disposed so as to meander in the first air passage 30 in the vehicle width direction. Since the end of the tube 72 is connected to the refrigerant pipe connection part 71, the refrigerant of the vapor compression refrigeration cycle flows into and out of the tube 72 via the refrigerant pipe connection part 71.

In the evaporator 70, a plurality of straight pipe portions of the tube 72 are arranged in the vehicle longitudinal direction, and a plurality of straight pipe portions are arranged in the vehicle vertical direction less than in the vehicle longitudinal direction. That is, predetermined intervals are formed between the straight pipe portions of each tube 72 in the vehicle front-rear direction and the vehicle vertical direction. Therefore, when the blown air F flowing through the first air passage 30 passes through the evaporator 70, it passes between the tubes 72 and exchanges heat with the refrigerant flowing inside the tubes 72.

The plurality of plate fins 73 are formed in a plate shape with a material having good heat conductivity, and are joined to the straight pipe portion of the tube 72 at intervals in the vehicle width direction as shown in FIG. I have. Therefore, the refrigerant flowing inside the tube 72 can absorb heat from the blast air F flowing through the first air passage 30 via the plate fins 73 in addition to the tube wall of the tube 72.

The refrigerant used in the refrigeration cycle is an HFC-based refrigerant (specifically, R134a), which constitutes a vapor compression subcritical refrigeration cycle in which the high-pressure side refrigerant pressure does not exceed the critical pressure of the refrigerant. doing. Of course, an HFO-based refrigerant (for example, R1234yf) or the like may be adopted as the refrigerant.

A second air passage 35 is formed inside the air conditioning case 10 on the vehicle front side. As shown in FIG. 1 and the like, the second air passage 35 is formed by a space between the rib 31 and a wall on the vehicle front side of the air conditioning case 10. In other words, the second air passage 35 extends in the vehicle width direction (that is, in the vehicle right direction and left direction) from the end of the first air passage 30 extending in the vehicle width direction central portion to the front of the vehicle.

部位 A portion of the second air passage 35 on the vehicle front side is closed by a wall surface of the air conditioning case 10 on the vehicle front side. Therefore, in the vehicle air conditioner 1, when the blown air F that has passed through the first air passage 30 flows into the second air passage 35, it hits the wall surface of the second air passage 35 on the vehicle front side.

(4) Inside the second air passage 35, an air volume distribution rib 36 is disposed. The air volume distribution rib 36 is located forward of a central portion of the air outlet 25 in the vehicle width direction. The horizontal cross section of the air volume distribution rib 36 has a substantially isosceles triangular shape. The air volume distribution rib 36 is arranged such that the vertex of the isosceles triangle is located on the first air passage 30 side.

為 For this reason, the air volume distribution rib 36 distributes the flow of the blown air flowing out of the first air passage 30 into two parts by the top and side surfaces of the air volume distribution rib 36. The air volume distribution rib 36 changes the direction of the distributed air flow into a flow flowing through the second air passage 35 to the right side of the vehicle and a flow flowing through the second air passage 35 to the left side of the vehicle.

Since the wall surface on the front side of the vehicle in the air-conditioning case 10 extends in the vehicle width direction, the blast air F distributed by the air volume distribution rib 36 is guided to the vehicle right direction and the vehicle left direction according to the wall surface. In other words, when flowing into the second air passage 35, the blown air F is distributed by the air volume distribution ribs 36 and then flows to the right and left of the vehicle according to the second air passage 35.

The vehicle front-side wall of the air-conditioning case 10 includes a vehicle front-side wall of the upper case 11 and a vehicle front-side wall of the lower case 13, as shown in FIG. The wall surface on the vehicle front side of the upper case 11 and the wall surface on the vehicle front side of the lower case 13 are fitted by an uneven fitting structure.

By adopting this structure, the wall surface on the front side of the vehicle in the air-conditioning case 10 ensures airtightness to the outside of the air-conditioning case 10. The second air passage 35 can guide the blast air F flowing into the second air passage 35 to the third air passage 40 without leaking to the outside of the air conditioning case 10.

Third air passages 40 are formed on both sides of the air conditioning case 10 in the vehicle width direction, and extend toward the rear side of the vehicle. That is, each third air passage 40 is formed at a position on the left and right sides of the vehicle with respect to the first air passage 30 and the evaporator 70 in the air conditioning case 10. The longitudinal direction of the vehicle corresponds to the first direction, and particularly, the rear side of the vehicle corresponds to one side of the first direction.

分配 As shown in FIG. 1, a distribution member 41 is disposed inside the third air passage 40 on the right side of the vehicle. The distribution member 41 distributes the blown air F flowing from the second air passage 35 into the third air passage 40 on the right side of the vehicle into two flows. That is, the third air passage 40 on the right side of the vehicle is divided by the distribution member 41 into a third air passage 40a located on the outside in the vehicle width direction and a third air passage 40b located on the inside in the vehicle width direction.

The distribution member 41 is also arranged inside the third air passage 40 on the left side of the vehicle. The distribution member 41 distributes the blown air F flowing from the second air passage 35 into the third air passage 40 on the left side of the vehicle into two flows. That is, the third air passage 40 on the left side of the vehicle is divided into a third air passage 40c located on the inner side in the vehicle width direction and a third air passage 40d located on the outer side in the vehicle width direction. In the following description, the third air passage 40 is treated as a generic term for the third air passage 40a to the third air passage 40d.

The third air passages 40 are connected to the second air passages 35 on both sides of the air-conditioning case 10 in the vehicle width direction, so that the blast air F passing through the second air passages 35 is guided to the vehicle rear side. be able to. That is, the second air passage 35 can change the direction of the flow of the blown air F that has passed through the first air passage 30 toward the front of the vehicle by 180 ° in the horizontal direction, and the vehicle travels inside the third air passage 40. It can be guided to the rear side.

{Circle around (3)} The third air passage 40 extends to the outlet 45 formed in the rear part of the vehicle on both sides of the air conditioning case 10 in the vehicle width direction. An outlet portion 45a is disposed at a rear portion of the vehicle in the third air passage 40a, and an outlet portion 45b is disposed at a rear portion of the third air passage 40b. Further, an outlet 45c is arranged in the rear part of the third air passage 40c, and an outlet 45d is arranged in the rear part of the third air passage 40d. The outlet 45 is a general term for the outlets 45a to 45d.

Each outlet 45 is formed by opening the lower case 13 on the vehicle rear side of the air conditioning case 10, and communicates the interior of the third air passage 40 in the air conditioning case 10 with the interior of the passenger compartment I. Therefore, the blown air F flowing through the third air passage 40 is blown out from the inside of the air-conditioning case 10 toward the vehicle rear side into the vehicle compartment I through the respective air outlets 45. The specific configuration of the outlet 45 will be described later with reference to the drawings.

Next, the flow of the blown air F in the vehicle air conditioner 1 will be described in detail with reference to FIG. When the air conditioning operation by the vehicle air conditioner 1 is started, the operation of the electric motor 21 of the blower 20 is started together with the operation of the compressor in the refrigeration cycle.

Accordingly, the operation of the blower 20 is started, and the air in the passenger compartment I is sucked into the air-conditioning case 10 via the suction port 16 of the fan accommodating portion 15 in the vehicle air conditioner 1.

As shown in FIG. 6, the air sucked from the suction port 16 is supplied to the first air as the blowing air F from the blowing port 25 formed on the vehicle front side of the fan accommodating section 15 with the operation of the blower 20. It is blown out into the passage 30.

The blown air F flowing into the first air passage 30 passes between the tube 72 and the plate fins 73 in the evaporator 70, and flows through the first air passage 30 toward the front of the vehicle. At this time, the blown air F is cooled by exchanging heat with the refrigerant in the evaporator 70.

Then, the blast air F that has passed through the evaporator 70 in the first air passage 30 passes above the rib 31 disposed on the vehicle front side of the air conditioning case 10 and flows into the second air passage 35. As shown in FIG. 6, the blown air F that has flowed into the second air passage 35 is blown by the air flow distribution ribs 36 into the blown air F flowing through the second air passage 35 to the right side of the vehicle and the second air passage 35 to the left side of the vehicle. It is distributed to the flowing blast air F.

風 As shown in FIG. 6, the air volume distribution rib 36 is disposed so as to face the center of the air outlet 25 in the vehicle width direction. For this reason, the air volume distribution rib 36 distributes the air volume of the blown air F flowing to the right side of the vehicle in the second air passage 35 and the air volume of the blown air F flowing to the left side of the vehicle in the second air passage 35. Can be.

The blast air F distributed to the right of the vehicle in the second air passage 35 flows to the right side of the vehicle along the front wall surface of the second air passage 35, and the third air passage 40 disposed on the right side of the air conditioning case 10 in the vehicle Flows into. On the other hand, the blown air F distributed to the left of the vehicle in the second air passage 35 flows to the right side of the vehicle along the front wall surface of the second air passage 35, and the third air disposed on the left side of the air conditioning case 10 on the vehicle side It flows into the passage 40.

When flowing into the third air passage 40 on the right side of the vehicle, the blown air F is distributed by the distribution member 41 into two flows of the blown air F flowing through the third air passage 40a and the blown air F flowing through the third air passage 40b. Is done.

The blown air F that has flowed to the rear side of the vehicle through the third air passage 40a is blown out from the outlet 45a into the vehicle compartment I. Then, the blown air F flowing to the rear side of the vehicle through the third air passage 40b is blown out from the outlet 45b into the vehicle interior I.

As described above, in the vehicle C according to the present embodiment, the third-row seat Sc is closer to the center side in the vehicle width direction than the second-row seat Sb in relation to the arrangement space for the rear wheels of the vehicle C. Arrangement. Therefore, the blown air F blown out from the outlet 45a easily reaches the vehicle right side of the second row seat Sb, and the blown air F blown out from the blowout part 45b is right side of the vehicle in the third row Sc. Is easier to reach.

On the other hand, when the blast air F flows into the third air passage 40 on the left side of the vehicle, the blast air F is distributed by the distribution member 41 into two flows: blast air F flowing through the third air passage 40c and blast air F flowing through the third air passage 40d. Distributed to

The blown air F that has flowed to the rear side of the vehicle through the third air passage 40c is blown out from the air outlet 45c into the vehicle interior I. Then, the blown air F that has flowed to the rear side of the vehicle through the third air passage 40d is blown into the vehicle interior I from the outlet 45d.

Due to the arrangement of the second row sheet Sb and the third row sheet Sc, the blown air F blown out from the outlet 45c easily reaches the left side of the vehicle of the third row Sc, and the blown air blown out from the outlet 45d. The air F easily reaches the vehicle left side of the second row seat Sb.

Thereby, according to the vehicle air conditioner 1, the blown air F whose temperature has been adjusted by the heat exchange in the evaporator 70 can be supplied from each of the outlets 45, so that the comfort in the passenger compartment I is improved. Can be done.

Next, a specific configuration of the air outlet 45 in the vehicle air conditioner 1 will be described in detail with reference to FIG. FIG. 7 shows a cross section taken along the line VII-VII in FIG. 1, and shows the internal configuration of the outlet 45d.

FIG. 7 shows the internal configuration of the air outlet 45d, but the internal configuration of the air outlets 45a to 45c is the same. Therefore, in the following description, the configuration of the outlet 45 will be described by taking the outlet 45d as an example.

As shown in FIG. 7, the outlet 45 is a portion where the blown air that has passed through the third air passage 40 is blown into the vehicle interior I, and has a blowout passage 46. The opening shape of the air outlet 45 is formed in a flat slit shape whose vertical direction is shorter than the vehicle left-right direction, which contributes to downsizing of the entire vehicle air conditioner 1 in the vertical direction.

The outlet passage 46 of each outlet 45 extends from the rear end of the third air passage 40 toward the rear side of the vehicle, and communicates with the interior of the passenger compartment I. The passage cross section of the outlet passage 46 is formed in a flat slit shape whose up-down direction is short with respect to the vehicle left-right direction.

As shown in FIG. 7, the outlet passage 46 is inclined and extended so as to be located lower as it goes toward the rear side of the vehicle. As described above, since the blown air F flows toward the rear side of the vehicle in the blowout passage 46, the blowout passage 46 is inclined so that the blowdown air F is located lower in the flow direction downstream of the blown air F.

The outlet passage 46 is formed in a pipe shape by a wall including an upper side wall 47 and a lower side wall 48. The upper side wall portion 47 constitutes a wall portion above the outlet passage 46, and extends obliquely so as to be positioned lower toward the rear of the vehicle.

The lower wall portion 48 is arranged at a predetermined interval below the upper side wall portion 47 and forms a wall portion below the blowing passage 46. The lower side wall portion 48 extends obliquely so as to be located lower toward the rear side of the vehicle, and is parallel to the upper side wall portion 47. As shown in FIG. 7, the lower end of the upper side wall 47 is located at the same height as the lower end of the lower side wall 48 and is arranged horizontally.

被覆 By configuring the blowing passage 46 as shown in FIG. 7, the covering portion 47 a and the exposed portion 47 b are formed on the upper side wall portion 47. The covering portion 47a is a portion of the upper side wall portion 47 which is covered by the lower side wall portion 48 with respect to the vehicle compartment I on the lower side. The exposed portion 47b is a portion that is located below the covering portion 47a in the upper side wall portion 47 and the lower side of the upper side wall portion 47 is exposed to the vehicle compartment I.

ガイド Then, as shown in FIGS. 1, 6, etc., a guide member 50 is disposed inside the blowout passage 46. The guide member 50 is supported so as to be rotatable in the vehicle left-right direction, and adjusts the flow of the blast air F passing through the blowing passage 46 in the vehicle left-right direction. The configuration of the guide member 50 will be described later with reference to the drawings.

下面 As shown in FIG. 7, a lower surface portion 49 is disposed at a lower end portion of the upper side wall portion 47 (that is, a lower end portion of the exposed portion 47b). The lower surface portion 49 extends horizontally from the lower end portion of the upper side wall portion 47 toward the vehicle rear side.

Here, since the opening shape of the blowing passage 46 has a flat slit shape whose vertical direction is short, the blast air F passing through the blowing passage 46 causes the upper wall portion 47 and the lower surface portion 49 by the so-called Coanda effect. Along the direction of the air flow. Therefore, the blowing direction of the blown air F that has passed through the blowing passage 46 changes substantially horizontally to the rear side of the vehicle C, and is guided along the surface of the lower surface portion 49.

フ Flaps 60 are disposed on the vehicle rear side of the lower surface portion 49. The flap 60 is attached to the air-conditioning case 10 at the vehicle rear side of the lower surface portion 49 so as to be rotatable in the vehicle vertical direction, and changes the blowing direction of the blown air F flowing along the lower surface portion 49 in the vertical direction. adjust.

Next, a configuration of the flap 60 disposed on the vehicle rear side of the lower surface portion 49 will be described with reference to FIG. As shown in FIGS. 1, 5, and 6, in the vehicle air conditioner 1, a flap 60 a is disposed on the vehicle rear side of the air outlet 45 a, and on the vehicle rear side of the air outlet 45 b. The flap 60b is arranged. A flap 60c is arranged on the vehicle rear side of the outlet 45c, and a flap 60d is arranged on the vehicle rear side of the outlet 45d.

Here, the flaps 60a to 60d have the same basic configuration. Therefore, in FIG. 8 and the following description, the flap 60d will be described as an example, and the description of the flaps 60a to 60c will be omitted. The flap 60 is a general term for the flaps 60a to 60d.

フ As shown in FIG. 8, the flap 60 has a flat plate portion 61, a reinforcing rib 62, and a rotation support portion 63, and the flat plate portion 61 and the like are integrally formed by resin molding. The flat plate portion 61 is a portion that occupies substantially the entire flap 60 in a top view, and is formed in a substantially rectangular flat plate shape.

The longitudinal direction of the flat plate portion 61 of the flap 60 is arranged in parallel with the longitudinal direction (vehicle left-right direction) of the outlet portion 45 located on the front side of the vehicle (that is, on the upstream side in the blowing direction). The lower surface of the flat plate portion 61 in the flap 60 is a guide surface for guiding the blown air F flowing along the surface of the lower surface portion 49.

補強 As shown in FIG. 8 and the like, a reinforcing rib 62 is disposed on the upper surface of the flat plate portion 61. The reinforcing rib 62 is arranged along the outer edge of the flat plate portion 61. The reinforcing ribs 62 include those that connect the reinforcing ribs 62 arranged along the front edge and the rear edge of the flat plate portion 61. These reinforcing ribs 62 reinforce the flat plate portion 61 of the flap 60, suppress deformation of the flat plate portion 61, and maintain a flat state.

The rotation support portion 63 is a portion for supporting the flap 60 so as to be vertically rotatable with respect to the air conditioning case 10. The rotation support portions 63 are arranged on the left and right sides of the flap 60 on the front side of the vehicle.

回動 And the rotation support part 63 is formed in the shape of a flat plate, and its normal direction is along the vehicle left-right direction. The rotation support portion 63 is formed with a circular support hole penetrating in the left-right direction of the vehicle. A cylindrical shaft formed behind the lower surface 49 in the air-conditioning case 10 is inserted into the support hole. Thereby, the flap 60 is attached to the air-conditioning case 10 on the vehicle rear side of the outlet 45 so as to be rotatable in the vehicle vertical direction.

Next, in the vehicle air conditioner 1 according to the present embodiment, adjustment of the flow of the blown air F blown out from the outlet 45 will be described with reference to FIG. As shown in FIG. 7, the blown air F blown out from the outlet 45 changes the flow direction along the lower end and the lower surface 49 of the upper side wall 47 by the so-called Coanda effect. As a result, the blown air F flows along the surface of the lower surface portion 49 in a substantially horizontal direction toward the vehicle rear side, and reaches the flap 60.

When the flap 60 is in a horizontal state along the surface of the lower surface 49, the lower surface of the flat plate 61 in the flap 60 is located on the same plane as the surface of the lower surface 49. In this case, as indicated by a broken line in FIG. 7, the blown air F flowing to the vehicle rear side along the lower surface portion 49 flows in the horizontal direction along the lower surface of the flat plate portion 61 in the flap 60, and then the vehicle compartment I Is blown toward the rear side of the vehicle air conditioner 1.

That is, the vehicle air conditioner 1 in this case guides the blowing direction of the blown air F blown out from the outlet 45 horizontally to the rear side of the vehicle C. Air F can be supplied. For example, in the case of such adjustment, the vehicle air conditioner 1 can supply the blast air F blown out from the outlet 45 to the occupant P of the third-row seat Sc disposed at the rearmost position.

Next, a description will be given of a case where the flap 60 is rotated to change the inclination angle of the flap 60. As described above, since the flap 60 is supported rotatably with respect to the air-conditioning case 10 about the cylindrical shaft portion, the occupant P of the vehicle C holds the rear side of the flap 60, It can be turned up and down around the shaft. Thereby, the occupant P can arbitrarily adjust the inclination angle of the lower surface of the flap 60 with respect to the lower surface portion 49.

As shown by the one-dot chain line in FIG. 7, when the turning operation is performed in a state where the rear side of the flap 60 is pulled down, the blast air F blown out from the outlet portion 45 is supplied to the vehicle along the lower surface portion 49. It flows backward and reaches the lower surface of the flap 60.

At this time, since the rear side of the flap 60 is in a lowered state, the blown air F flows toward the rear side and the lower side of the vehicle air conditioner 1 along the lower surface of the flat plate portion 61 of the flap 60.

In other words, the vehicle air conditioner 1 in this case supplies the blown air F blown out from the outlet 45 more forward than when the flap 60 is in a horizontal state along the surface of the lower surface 49. be able to. For example, when adjusted in this way, the vehicle air conditioner 1 sends the blast air F blown out from the outlet 45 to the occupant P of the second-row seat Sb disposed forward of the third-row seat Sc. Can be supplied.

As described above, the vehicle air conditioner 1 according to the present embodiment is configured such that the blowing direction of the blown air F blown out from the outlet 45 according to the inclination angle adjusted by the turning operation of the flap 60 in the vertical direction. Can be arbitrarily adjusted in the vertical direction. As a result, according to the vehicle air conditioner 1, the supply destination of the blown air F blown out from the outlet port 45 can be adjusted in the vehicle front-back direction inside the vehicle interior I.

Next, the configuration of the guide member 50 disposed in the outlet passage 46 of each outlet port 45 will be described with reference to the drawings. FIG. 9 shows a cross section taken along the line IX-IX in FIG. 1, and shows a configuration of the guide member 50d inside the air outlet portion 45d. FIG. 10 is an enlarged view of the periphery of the guide member 50 in FIG.

FIG. 9 shows the configuration of the guide member 50d inside the outlet port 45d as in FIG. 7, but the guide member 50a and the guide in the outlet port 45a, the outlet port 45b, and the outlet port 45c. The configuration of the member 50b and the guide member 50c is the same.

Therefore, in the following description, the configuration of the guide member 50 in the outlet 45 will be described by taking the guide member 50d inside the outlet 45d as an example. The guide member 50 is a general term for the guide members 50a to 50d.

As shown in FIG. 1, FIG. 5, FIG. 6, etc., the vehicle air conditioner 1 according to the present embodiment includes guide members 50a to 50d inside the outlet passages 46 in the outlet portions 45a to 45d. have. Each guide member 50 is formed in a flat plate shape extending along the inside of the blowing passage 46, and is attached so as to be rotatable around a support portion 55 arranged on the upper side wall portion 47.

As described above, the outlet passage 46 in each outlet portion 45 is configured to have a flat opening shape in which the size in the vehicle vertical direction is shorter than the size in the vehicle width direction. Each guide member 50 is formed in a flat plate shape whose longitudinal dimension is set to a predetermined length L and whose short dimension is slightly shorter than the dimension of the outlet passage 46 in the vehicle vertical direction.

As shown in FIGS. 9 and 10, each guide member 50 is rotatably supported by a support portion 55 arranged on the upper side wall portion 47 of the blowout passage 46. The rotation axis of the support portion 55 is perpendicular to the upper side wall portion 47. Therefore, each guide member 50 is attached to the inside of the outlet passage 46 in the outlet portion 45 so as to be rotatable in the vehicle left-right direction around the support portion 55. The vehicle width direction (vehicle left-right direction) intersects at right angles to the vehicle front-rear direction corresponding to the first direction, and corresponds to the second direction.

Each guide member 50 is operated to guide the flow of the blast air F passing through the blowing passage 46 and to rotate the guide member 50 in the vehicle width direction inside the blowing passage 46. And a knob operating section 52.

The air guide 51 of the guide member 50 is located upstream of the support 55 with respect to the blowing direction of the blown air F in the blow-out passage 46. As shown in FIGS. 9 and 10, most of the air guide 51 is located between the upper wall 47 and the lower wall 48. In other words, the air guide portion 51 is located below the covering portion 47 a of the upper side wall portion 47 inside the blowing passage 46.

The air guide section 51 guides the flow of air passing through the blow-out passage 46, and changes the blowing direction of the blown air F blown from the blow-out section 45 in accordance with the position in the vehicle width direction inside the blow-out path 46. Adjust in the vehicle width direction.

The knob operating portion 52 is a portion that is held by the occupant P when the guide member 50 is rotated in the vehicle width direction. As shown in FIGS. 9 and 10, the knob operation section 52 is located downstream of the air guide section 51 and the support section 55 with respect to the blowing direction of the blown air F in the blowing passage 46. The knob operation unit 52 corresponds to an operation unit.

That is, the knob operation part 52 is located below the exposed part 47b in the upper side wall part 47 of the outlet part 45, and is arranged at a position facing the exposed part 47b. For this reason, the knob operation section 52 faces the inside of the vehicle compartment I without being hindered by the lower wall section 48.

Therefore, the occupant P inside the vehicle C can easily pinch the knob operation section 52 from below the air conditioner 1 for the vehicle, and can rotate the guide member 50 in the left and right direction of the vehicle. Thereby, according to the vehicle air conditioner 1, the blowing direction of the blowing air F blown out from the outlet port 45 can be easily adjusted to an arbitrary direction in the vehicle width direction.

As shown in FIGS. 9 and 10, the knob operating portion 52 of the guide member 50 is formed above the lower ends of the upper wall portion 47 and the lower wall portion 48 and below the exposed portion 47b of the upper wall portion 47. It is arranged by effectively utilizing the dead space. Since the guide member 50 does not protrude significantly below the air-conditioning case 10, the vehicle air-conditioning system 1 is used to reduce the size of the vehicle air-conditioning system 1 in the vertical direction of the vehicle and to secure a living space in the passenger compartment I. Can contribute.

The support portion 55 is disposed on the exposed portion 47b in the upper side wall portion 47 of the blow-out passage 46, and supports the guide member 50 so as to be rotatable in the vehicle width direction. The support portion 55 is attached to the guide member 50 at a position offset toward the knob operation portion 52 with respect to the entire length L of the guide member 50.

Therefore, when the guide member 50 is rotated around the support portion 55 in the vehicle width direction, the movement amount on the wind guide portion 51 side is larger than the movement amount on the knob operation portion 52 side. That is, according to the vehicle air conditioner 1, the wind guide unit 51 can be largely rotated by a small rotation operation on the knob operation unit 52, and the blowing direction of the blown air F blown out from the outlet 45 is changed. It is possible to efficiently adjust the width of the vehicle.

Next, in the vehicle air conditioner 1 according to the present embodiment, adjustment of the flow of the blast air F inside the outlet passage 46 of the outlet portion 45 will be described with reference to FIGS. 11 and 12. As described above, in the air conditioner 1 for a vehicle, the blast air F flowing through the second air passage 35 flows into the third air passage 40 on the left side and the right side of the vehicle, and is supplied to the outlet port by the distribution member 41. It is distributed every 45.

(4) The blast air F distributed by the distribution member 41 disposed on the right side of the vehicle flows into the

outlets

45a and 45b disposed on the right side of the vehicle of the vehicle air conditioner 1. Here, the distribution member 41 on the right side of the vehicle is arranged so as to evenly distribute the blast air flowing through the second air passage 35 to the right side of the vehicle, and to guide the air to the

outlets

45a and 45b.

Then, the blast air F distributed by the distribution member 41 disposed on the left side of the vehicle flows into the

outlets

45c and 45d disposed on the left side of the vehicle air conditioner 1. Here, the distribution member 41 on the left side of the vehicle is arranged so as to evenly distribute the blast air flowing to the left side of the vehicle through the second air passage 35 and to guide the air to the outlet 45c and the outlet 45d.

As shown in FIGS. 11 and 12, each distribution member 41 has a front end (i.e., an end on the upstream side in the blowing direction of the blown air F) having a predetermined front space Df and a predetermined inside space Di. Are arranged as follows. The front interval Df refers to the interval between the front end of the distribution member 41 and the inner wall surface of the air-conditioning case 10 on the vehicle front side, and the inside interval Di is defined as the distance between the front end of the distribution member 41 with respect to the vehicle width direction inside. Means interval.

The front interval Df of the distribution member 41 on the right side of the vehicle corresponds to the volume of the blown air F flowing into the outlet 45a, and the inner interval Di corresponds to the volume of the blown air F flowing to the outlet 45b. . The front space Df and the inside space Di in the distribution member 41 on the right side of the vehicle are determined so that the air volume of the blown air F at the air outlet 45a and the air volume of the blown air F at the air outlet 45b are equal.

On the other hand, the inner space Di in the distribution member 41 on the left side of the vehicle corresponds to the air volume of the blown air F flowing into the outlet 45c, and the front space Df corresponds to the air volume of the blown air F flowing into the outlet 45d. ing. The front interval Df and the inner interval Di of the distribution member 41 on the left side of the vehicle are determined so that the air volume of the blown air F at the outlet 45c and the air volume of the blown air F at the outlet 45d are equal.

That is, the vehicle air conditioner 1 is configured such that the blowing air F is blown out from the outlets 45a to 45d arranged side by side in the vehicle width direction with a uniform air volume. A guide member 50 is attached to the inside of the air outlet passage 46 of each of the air outlets 45a to 45d so as to be rotatable in the vehicle width direction.

(4) When the guide member 50 is rotated in the vehicle width direction, the position and the posture of the air guide 51 inside the air outlet passage 46 change in the vehicle width direction. For this reason, the blowing direction of the blown air F blown out from the outlet 45 changes to an arbitrary direction in the vehicle width direction by the rotation operation of the guide member 50 about the support portion 55.

As shown in FIGS. 11 and 12,

guide members

50 a, 50 b, 50 c, and 50 d are provided at the

outlet portions

45 a, 45 b, 45 c, and 45 d. Are located. The guide member 50a, the guide member 50b, the guide member 50c, and the guide member 50d are respectively independently rotatably mounted in the vehicle width direction.

Therefore, according to the air conditioner 1 for a vehicle, the direction of the blown air F blown out from the plurality of outlets 45 arranged side by side in the vehicle width direction is changed by rotating each guide member 50 in the vehicle width direction. By doing so, it is possible to individually adjust in any direction in the vehicle width direction.

In the vehicle air conditioner 1, on the vehicle rear side of each air outlet 45, each flap 60 is disposed so as to be rotatable in the vertical direction of the vehicle. Therefore, by rotating the flap 60 in the vertical direction of the vehicle, the blowing direction of the blown air F blown out from the outlet 45 can be adjusted to an arbitrary direction in the vertical direction of the vehicle.

That is, according to the vehicle air conditioner 1, the blowing direction of the blowing air F blown out from the four outlets 45 arranged side by side in the vehicle width direction is changed to any direction in the vehicle width direction and the vehicle vertical direction. Can be adjusted.

As a result, the vehicle air conditioner 1 supplies the blown air F blown out from each outlet 45 to an arbitrary position on the rear side of the vehicle air conditioner 1 in the vehicle compartment I, Or can be supplied. By realizing various supply modes related to the blast air F, the vehicle air conditioner 1 can respond to the demands of the occupants P in the passenger compartment I, respectively, and can increase the comfort of the occupants P.

As described above, the vehicle air conditioner 1 according to the present embodiment is disposed on the ceiling R of the vehicle C, and is configured to house the blower 20 and the evaporator 70 inside the air conditioning case 10. The vehicle air conditioner 1 controls the temperature of the blown air F flowing through the inside of the air conditioning case 10 with the operation of the blower 20 by the evaporator 70 and supplies the blown air F into the cabin I of the vehicle C. The comfort of the occupant P can be improved.

Further, according to the vehicle air conditioner 1, since each of the air outlets 45 is formed in a flat slit shape in which the vertical direction is short with respect to the vehicle left-right direction, the vertical size of the entire device is reduced. Therefore, a large living space in the vehicle compartment I can be secured.

As shown in FIGS. 9 to 12 and the like, in the vehicle air conditioner 1, a guide member 50 is provided with a vehicle width in a blow-out passage 46 of a blow-off portion 45 formed in a flat slit shape having a short vehicle vertical direction. It is arranged to be rotatable in the direction.

For this reason, even in the case of the air outlet unit 45 formed in a flat slit shape having a short vertical direction, the air conditioner 1 for a vehicle can control the flow of the blown air F blown out from the air outlet unit 45 in an arbitrary manner in the vehicle width direction. In the direction of the vehicle, and the airflow mode desired by the occupant P in the vehicle width direction can be realized.

ツ As shown in FIG. 10, the knob operating portion 52 of the guide member 50 is disposed at a position facing the exposed portion 47b of the upper side wall portion 47. For this reason, according to the vehicle air conditioner 1, even if the air outlet part 45 is formed in a flat slit shape having a short vertical direction, the occupant P of the passenger compartment I can operate the knob operating part of the guide member 50 from below. 52 can be easily accessed.

Thereby, the vehicle air conditioner 1 can improve the operability of the guide member 50 in the vehicle width direction, and can accurately adjust the wind direction in the vehicle width direction inside the cabin I.

ガイド As shown in FIG. 10, the guide member 50 is rotatably supported in the vehicle width direction by a support portion 55 disposed on the exposed portion 47b of the upper side wall portion 47. Further, the support portion 55 supports the guide member 50 at a position deviated toward the knob operation portion 52 with respect to the entire guide member 50. For this reason, when the guide member 50 rotates in the vehicle width direction, the amount of movement on the wind guide unit 51 side is larger than the amount of movement on the knob operation unit 52 side.

Therefore, according to the vehicle air conditioner 1, with respect to the turning operation of the guide member 50 in the vehicle width direction, the blowing direction of the blowing air F blown out from the outlet port 45 can be changed by a small operation on the knob operating portion 52. It can be largely changed in the width direction.

In the above-described embodiment, the vehicle air conditioner 1 has a configuration in which the blast air F cooled by the evaporator 70 is supplied from the outlet portion 45 into the vehicle compartment I, but is not limited to this mode. Absent. For example, as a configuration for adjusting the temperature of the blown air F, the blown air may be heated using a heat exchanger such as a condenser or a heater core of a refrigeration cycle device. Further, as a configuration for adjusting the temperature of the blown air F, a Peltier element, an electric heater, or the like may be employed.

Further, the vehicle air conditioner 1 does not necessarily need to adjust the temperature of the blown air F, and may be configured as a configuration (that is, a circulator) in which the air sucked into the air conditioning case 10 is directly blown out from the outlet port 45. It is possible.

In the above-described embodiment, the blast air F is blown out toward the rear side of the vehicle along the third air passage 40, and the blast direction of the blast air F is changed to the width of the vehicle by rotating the guide member 50. The adjustment is made in an arbitrary direction (vehicle left-right direction), but is not limited to this mode.

では Various directions can be adopted as the first direction and the second direction instead of the mode in which the vehicle longitudinal direction is the first direction and the vehicle width direction is the second direction as in the above-described embodiment. For example, the vehicle air conditioner 1 may be arranged on the ceiling R of the vehicle C such that the vehicle width direction is the first direction and the vehicle front-rear direction is the second direction.

In the above-described embodiment, the first air passage 30, the second air passage 35, and the third air passage 40 are provided as the air passages for the blown air F in the air conditioning case 10, but the present invention is not limited to this embodiment.
