Air is blown out from the exit 51 toward the face of the occupant 3.

  In the vicinity of the downstream end of the front face duct 50, a blowing grill 60 that blows out the blown air guided by the front face duct 50 is connected, and the blowing grill 60 is located on the right front side of the occupant 3. Air is blown out from the upper body outlets 61 to 63 provided in the outlet grill 60 toward the upper body (chest and abdomen) excluding the face of the occupant 3.

  The blowout grill 60 is disposed below the face blowout opening 51. In other words, the upper body outlets 61 to 63 of the outlet grill 60 are disposed below the face outlet 51. The front face duct 50 and the blowout grill 60 constitute the air guide member of the present invention.

  A rear face duct 70 extending upward is connected to the rear face opening 28, and air blown out from a rear face outlet 71 at the downstream end of the rear face duct 70 flows from the rear side of the occupant 3. It is blown out toward the rear.

  As shown in FIGS. 3 and 4, a foot passage 29 communicating with the air mix chamber 24 is formed in the case 11 on the front side of the cabin of the hot air passage 23. The foot passage 29 is formed so as to hang downward from above.

  A foot opening 30 is opened on the front side wall surface of the case below the foot passage 29. A foot duct 80 (see FIG. 1) extending toward the cabin front side is connected to the foot opening 30, and a foot portion of the occupant 3 from a foot outlet 81 (see FIG. 1) at the downstream end of the foot duct 80. It is designed to blow out air.

  On the front side of the cabin of the air mix chamber 24, a plate-like blowing mode switching door 31 that switches between the face / diff passage 25 and the foot passage 29 is disposed. One end of the rotating shaft 31a of the blow mode switching door 31 protrudes outside the case 11 and is connected to an electric actuator (not shown).

  In FIG. 4, the solid line position of the blowing mode switching door 31 indicates the position in the face mode in which the foot passage 29 is fully closed and the face / diff passage 25 is fully opened. On the other hand, the two-dot chain line position of the blowing mode switching door 31 indicates a foot mode position in which the face / diff passage 25 is fully closed and the foot passage 29 is fully opened.

  The plate-like differential door 32 that opens and closes the differential opening 26 adjusts the amount of air blown from the differential outlet. One end of the rotation shaft 32a of the differential door 32 protrudes outside the case 11 and is connected to an electric actuator (not shown). The solid line position of the differential door 32 indicates a position where the differential opening 26 is fully closed. On the other hand, the position of the two-dot chain line of the differential door 32 indicates a position where the differential opening 26 is fully opened.

  The plate-like rear face door 32 that opens and closes the rear face opening 28 includes a blowout air amount for the face 51, a blowout port for the blowout grill 60, and a blowout air amount from the differential blowout port, and a blowout air amount from the rear face blowout port 71. This adjusts the air volume ratio. One end of the rotating shaft 32a of the rear face door 32 protrudes outside the case 11 and is connected to an electric actuator (not shown). The solid line position of the rear face door 32 indicates a position where the rear face opening 28 is fully opened. On the other hand, the two-dot chain line position of the rear face door 32 indicates a position where the rear face opening 28 is fully closed.

  Next, the blowing grill 60 will be described. 5A is a front view of the blowing grill 60 of FIG. 1 as viewed from the front of the cabin, FIG. 5B is a right side view of FIG. 5A, and FIG. 6 is FIG. 5A. It is sectional drawing which follows the DD line.

  As shown in FIGS. 5 and 6, the blowing grill 60 has a circular mounting portion 64 rotatably fitted in a circular opening (not shown) of the front face duct 50 (see FIG. 1). By rotating the blowing grill 60, the vertical direction of the air blown from the blowing grill 60 can be adjusted.

  The blown air guided by the front face duct 50 flows into the blow grill 60 from the air inlet 65 surrounded by the mounting portion 64 and then blows out from the first to third upper body blow outlets 61 to 63. It is like that. The first to third upper body outlets 61 to 63 are arranged in a line in the vertical direction. As a result, the blow-out grill 60 has a vertically long shape and a small size in the left-right direction of the cabin, and the amount of protrusion to the center side of the cabin 1 (that is, the front side of the occupant 3) is small. Can be reduced.

In the blow-out grill 60, two first upper body blow-out openings 61 are arranged at the center in the vertical direction, and two second upper body blow-out openings 62 are adjacent to both sides of the first upper body blow-out opening 61 in the vertical direction. Further, two third upper body outlets 63 are arranged adjacent to both sides of the second upper body outlet 62 in the vertical direction.

The air e flowing into the blowing grill 60 from the front face duct 50 flows toward the first upper body outlet 61 while changing the horizontal direction in the blowing grill 60, and changes the horizontal direction and the vertical direction. However, the air flows toward the second upper body outlet 62 and the third upper body outlet 63. Further, the amount of change in the vertical direction of the inflow air e is greater in the flow toward the third upper body outlet 63 than in the flow toward the second upper body outlet 62.

  Since the flow toward the first upper body outlet 61 has the least change in direction, the wind speed of the blown air f blown from the first upper body outlet 61 is from the other upper body outlets 62 and 63. It becomes higher than the wind speed of the blown-out air g and h. Further, the wind speed of the blown-out air g blown out from the second upper body blowout opening 62 is higher than the wind speed of the blowout air h blown out from the third upper body blowout opening 63.

  Of the inner wall surface of the blow-out grill 60, the flow of the inflowing air e is caused by the inner wall surface (hereinafter referred to as a guide surface) 66 facing the air inlet 65 and continuing to the first to third upper body outlets 61 to 63. The direction is changed, and the blowing directions of the blowing airs f, g, and h blown from the first to third upper body outlets 61 to 63 are determined.

  Note that the guide surface 66 connected to the first upper body outlet 61, the guide surface 66 connected to the second upper body outlet 62, and the guide surface 66 connected to the third upper body outlet 63 have a direction in plan view. Accordingly, the blowing directions of the blowing airs f, g, and h blown out from the first to third upper body outlets 61 to 63 are different in plan view.

  Specifically, as shown in FIG. 2, the blown air f with the highest wind speed blown out from the first upper body outlet 61 is the side of the upper body of the occupant 3 that is farther from the blowing grill 60 (that is, the occupant 3 Blows out toward the left side of the upper body).

  Further, the blown air h having the lowest wind speed blown out from the third upper body outlet 63 is blown out toward the side closer to the blowing grill 60 in the upper body of the occupant 3 (that is, the right side portion of the upper body of the occupant 3). The

  Further, the medium-speed blown air g blown out from the second upper body blowout port 62 is blown out between the blown air f and the blown air h (that is, an intermediate portion in the left-right direction in the upper body of the occupant 3).

  Although not shown in the drawings, the air conditioning operation panel is provided on an instrument panel disposed in the front part of the cabin 1, and includes a compressor operation switch, an air flow switch, a temperature setting switch, a blow mode switching switch, It has a front / rear air volume adjustment switch, an inside / outside air mode switch, and the like.

  Next, the operation of this embodiment will be described. When the compressor operation switch on the air conditioning operation panel is turned on, the electromagnetic clutch of the compressor in the refrigeration cycle is energized and the electromagnetic clutch is in a connected state, so that the compressor is driven by the engine. Thereby, in the cooling heat exchanger 19, the low-temperature low-pressure refrigerant in the refrigeration cycle absorbs heat from the air and evaporates to cool the air.

  When the auto switch is turned on, the adjustment of the temperature of the conditioned air and the switching of the blowing mode are automatically performed according to the set temperature set by the temperature setting switch. The adjustment of the temperature of the conditioned air and the switching of the blowing mode can also be performed by manual operation.

  As described above, the temperature of the conditioned air is adjusted by operating the air mix door 21 and adjusting the mixing ratio of the cold air flowing through the cold air bypass passage 22 and the hot air flowing through the hot air passage 23.

  The blow-out mode includes a face mode that is mainly selected during cooling in summer and a foot mode that is mainly selected during heating in winter.

  In the face mode normally used during cooling in summer, the blowing mode switching door 31 is in a position where the face / diff passage 25 is fully opened (solid line position), and the differential door 32 is in a position where the differential opening 26 is fully closed (solid line position). And the rear face door 32 is operated so as to be in a position (solid line position) where the rear face opening 28 is fully opened.

  Thus, the conditioned air (cold air) is blown out from the rear face air outlet 71 toward the rear periphery of the occupant 3 through the rear face opening 28 and the rear face duct 70. The conditioned air is blown out from the face outlet 51 toward the face of the occupant 3 through the front face opening 27 and the front face duct 50. Furthermore, the conditioned air diverted from the front face duct 50 toward the blow grill 60 is blown toward the upper body of the occupant 3.

  For example, when the amount of air blown to the face of the occupant 3 is to be increased, such as when a window is opened, the rear face door 32 is moved to a position in which the rear face opening 28 is closed. May be manipulated.

  As described above, the blown air f having the highest wind speed among the blown airs f, g, and h blown out from the first to third upper body blowout ports 61 to 63 is far from the blowout grill 60 in the upper body of the occupant 3. The blown-out air h blown out toward the side and blown out from the third upper-body blow-out opening 63 is blown out toward the side closer to the blow-out grill 60 in the upper half of the occupant 3.

  Thereby, the air volume which reaches | attains the left side part in the upper body of the passenger | crew 3 and the air volume which reaches | attains the right side part can be made substantially equal. Accordingly, even in a layout in which air-conditioning air is blown from the left or right position ahead of the occupant 3 toward the upper body of the occupant 3, the air is distributed in a balanced manner on the left and right sides of the upper body of the occupant 3, so The cooling feeling of the passenger 3 can be improved.

  In the face mode, the conditioned air is blown from the face outlet 51 toward the face of the occupant 3 and the conditioned air is blown from the first to third upper body outlets 61 to 63 toward the occupant 3 upper body. Therefore, the cooling feeling (punch force) can be increased. In addition, it is favorable when the air volume ratio between the conditioned air blown from the face outlet 51 and the conditioned air blown from the first to third upper body outlets 61 to 63 is set to about 7: 3 or 6: 4. A cooling feeling is obtained.

(Second Embodiment)
A second embodiment of the present invention will be described. FIG. 7 is a front view of a state in which the blowout grill 60 in the vehicle air conditioner according to the second embodiment is viewed toward the front of the cabin. The present embodiment is different from the first embodiment in the configuration of the blowing grill 60. Since other aspects are the same as those in the first embodiment, only different parts will be described.

  As shown in FIG. 7, the blowing grill 60 of the present embodiment includes three neck outlets 67 for blowing air toward the neck portion of the occupant 3 and three foot blowings for blowing air toward the feet of the occupant 3. An outlet 68 is provided.

  The neck outlet 67 is disposed adjacent to the first to third upper body outlets 61 to 63, and the foot outlet 68 is disposed below the first to third upper body outlets 61 to 63. Adjacent to each other. The first to third upper body outlets 61 to 63, the neck outlet 67, and the foot outlet 68 are arranged in a line in the vertical direction.

  According to this, since the air blown out from the blow-out grill 60 is also diffused in the vertical direction so as to blow air to the feet of the occupant 3 as well, a cold wind feeling is given to the lower body where cold air has not reached so far. The cooling feeling can be further improved.

(Third embodiment)
A third embodiment of the present invention will be described. FIG. 8 is a perspective view of the inside of the cabin 1 of the hydraulic excavator equipped with the vehicle air conditioner according to the third embodiment, and FIG. 9 is a front view of the blowout grill 60 of FIG. 8 as viewed from the front of the cabin. . In the present embodiment, the configurations of the front face duct 50 and the blowout grill 60 are different from those of the first embodiment. Since other aspects are the same as those in the first embodiment, only different parts will be described.

  As shown in FIG. 8, in this embodiment, the face outlet 51 of the front face duct 50 is abolished.

  As shown in FIG. 9, the blowout grill 60 has three face blowout openings 69 for blowing air toward the face of the occupant 3 and three foot blowout openings 68 for blowing out air toward the legs of the occupant 3. I have.

  The face outlet 69 is disposed adjacent to the first to third upper body outlets 61 to 63, and the foot outlet 68 is disposed below the first to third upper body outlets 61 to 63. Adjacent to each other. The first to third upper body outlets 61 to 63, the face outlet 69, and the foot outlet 68 are arranged in a line in the vertical direction.

  According to this, the front face duct 50 can be simplified. In addition, since the air is also blown to the foot side of the occupant 3, it is possible to give a cool air feeling to the lower body where cold air has not reached so far, and to further improve the cooling feeling.
