  For example, in Patent Document 1, a louver is installed at an auxiliary outlet. The louver adjusts the wind direction at the auxiliary outlet. The rotation of the centrifugal fan casing is not assumed in adjusting the wind direction. A drive motor required for rotating the casing is not disclosed.

  According to some aspects of the present invention, when an auxiliary housing is attached to at least one side of a heat exchanger, air that can reliably prevent a situation such as disconnection of a wiring of a drive motor that drives the auxiliary housing. A harmony machine can be provided.

One embodiment of the present invention is arranged on at least one of a heat exchanger, a structure that houses the heat exchanger in a passage of airflow from a suction port to an outlet , and both left and right sides of the structure. , an auxiliary housing having an air blower spaced from said passage, coupled to said structure, prior to a side panel having a wall which partitions Kioku blower and said heat exchanger is installed in the side panels, A mounting plate that overlaps the wall body on the first surface, supports the auxiliary housing on a second surface on the back side of the first surface, and supports the auxiliary housing movably with respect to the side panel ; And an air conditioner including a drive motor fixed to a first surface of the mounting plate and connected to the auxiliary housing by power transmission means.

  In such an air conditioner, a cold or warm air stream is generated by the action of the heat exchanger. Air flow of room temperature air is blown out from the auxiliary air outlet. There is a temperature difference between the air flow of room temperature air blown out from the auxiliary air outlet and the air flow of cold air or warm air generated by the heat exchanger. Since the specific gravity of the air changes according to the temperature, the direction and movement of the air flow of the room temperature air can be controlled according to the difference in specific gravity. Cool air and warm air can be sent to a desired place indoors. Thus, the indoor temperature environment can be efficiently adjusted.

The power of the drive motor is transmitted to the auxiliary housing by the power transmission means. The auxiliary housing moves in response to the supply of power from the drive motor. In this way, the direction of the air flow of room temperature air can be adjusted. Since the drive motor is fixed not to the movable side such as the auxiliary housing but to the fixed side such as the wall body, shaking of the wiring of the drive motor is avoided when the auxiliary housing is moved. Therefore, a situation such as disconnection of the wiring can be reliably prevented. Moreover, after the mounting plate is overlaid on the wall body and the auxiliary housing is mounted on the side panel, the drive motor can be mounted on the mounting plate from the inside of the wall body. Since there is no protrusion on the first surface of the mounting plate prior to the mounting of the drive motor, the mounting plate can be stacked on the wall even if the mounting plate is moved in parallel along the wall surface. Since the mounting direction of the mounting plate is not limited, the degree of freedom of the shape of the side panel increases. If a protrusion is present on the first surface of the mounting plate, the mounting plate must be mounted from the vertical direction on the wall surface, and the side panel must be molded to avoid a movement path during mounting. Thus, the shape of the side panel is limited.

  The power transmission means may include an internal gear mounted on the auxiliary housing and a gear coupled to the drive motor and meshing with the internal gear. For example, the drive motor can be disposed at a position closer to the rotation axis of the auxiliary housing as compared with the case where the external gear is mounted on the auxiliary housing, such as when the auxiliary housing is rotated. The wall can be miniaturized. Such arrangement of the drive motor and downsizing of the wall body can contribute to downsizing of the unit including the side panel and the auxiliary housing.

  In the air conditioner, the drive motor is disposed at a position that extends parallel to the inner wall surface of the side panel and enters inward toward the heat exchanger from a virtual plane that contacts the side end of the heat exchanger. Can do. The heat exchanger and the drive motor overlap in a front view of the air conditioner. Thus, although the drive motor is disposed on the inner wall surface of the wall, an increase in the size of the air conditioner can be avoided.

  The drive motor may be disposed in a space deviated from a space located below the heat exchanger in the gravitational direction when installed. If the drive motor is disposed at a position deviated from the lower side in the gravity direction of the heat exchanger, even if condensation occurs in the heat exchanger, the drive motor will not be immersed in the falling water droplets. The drive motor can be protected from condensation water.

  At the time of installation, the air conditioner may further include a water shielding member that is disposed below the heat exchanger in the gravity direction and above the drive motor in the gravity direction and blocks water from falling. Even if water drops fall according to the condensation of the heat exchanger, the dropped water drops are blocked by the water shielding member. Therefore, even if the drive motor enters the space below the direction of gravity of the heat exchanger, the drive motor will not be immersed in the falling water droplets. The drive motor can be reliably protected from condensation water.

  The water shielding member may be formed on a heat exchanger holder connected to the wall surface while holding the heat exchanger. An increase in the number of parts can be avoided when the drive motor is blocked.

  As described above, according to the disclosed air conditioner, when the auxiliary housing is attached to at least one side of the heat exchanger, it is possible to reliably prevent a situation such as disconnection of the wiring of the drive motor that drives the auxiliary housing. it can.

The indoor unit 12 is installed in an indoor space in a building, for example. In addition, the indoor unit 12 may be installed in an environmental space corresponding to the indoor space. An indoor heat exchanger 14 is incorporated in the indoor unit 12. The outdoor unit 13 includes a compressor 15, an outdoor heat exchanger 16, an expansion valve 17, and a four-way valve 18. The indoor heat exchanger 14, the compressor 15, the outdoor heat exchanger 16, the expansion valve 17 and the four-way valve 18 form a refrigeration circuit 19.

  The refrigeration circuit 19 includes a first circulation path 21. The first circulation path 21 connects the first port 18a and the second port 18b of the four-way valve 18 to each other. A compressor 15 is provided in the first circulation path 21. The suction pipe 15a of the compressor 15 is connected to the first port 18a of the four-way valve 18 via a refrigerant pipe. The gas refrigerant is supplied to the suction pipe 15a of the compressor 15 from the first port 18a. The compressor 15 compresses the low-pressure gas refrigerant to a predetermined pressure. The discharge pipe 15b of the compressor 15 is connected to the second port 18b of the four-way valve 18 via a refrigerant pipe. Gas refrigerant is supplied from the discharge pipe 15 b of the compressor 15 to the second port 18 b of the four-way valve 18. The first circulation path 21 is formed by a refrigerant pipe such as a copper pipe.

  The refrigeration circuit 19 further includes a second circulation path 22. The second circulation path 22 connects the third port 18c and the fourth port 18d of the four-way valve 18 to each other. The outdoor heat exchanger 16, the expansion valve 17, and the indoor heat exchanger 14 are incorporated into the second circulation path 22 in order from the third port 18c side. The outdoor heat exchanger 16 realizes heat energy exchange between the refrigerant passing therethrough and ambient air. The indoor heat exchanger 14 realizes heat energy exchange between the refrigerant passing therethrough and ambient air. The second circulation path 22 may be formed by a refrigerant pipe such as a copper pipe.

  A blower fan 23 is incorporated in the outdoor unit 13. The blower fan 23 ventilates the outdoor heat exchanger 16. The blower fan 23 generates an air flow according to the rotation of the impeller, for example. The airflow passes through the outdoor heat exchanger 16. The flow rate of airflow passing through is adjusted according to the number of revolutions per minute of the impeller. In the outdoor heat exchanger 16, the amount of heat energy exchanged between the refrigerant and the air is adjusted according to the flow rate of the airflow.

  The indoor unit 12 includes a main unit 25 and a pair of fan units 26. The main body unit 25 incorporates the indoor heat exchanger 14 and the first blower fan 27. The first blower fan 27 ventilates the indoor heat exchanger 14. The 1st ventilation fan 27 produces | generates an airflow according to rotation of an impeller. Indoor air is sucked into the main unit 25 by the action of the first blower fan 27. The indoor air passes through the indoor heat exchanger 14 and exchanges heat with the refrigerant. The heat-exchanged cold air or warm air flow is blown out from the main unit 25. The flow rate of airflow passing through is adjusted according to the number of revolutions per minute of the impeller. In the indoor heat exchanger 14, the amount of heat energy exchanged between the refrigerant and the air can be adjusted according to the flow rate of the airflow. The fan unit 26 sucks room air and blows out the room air. In the fan unit 26, the room air is blown out at room temperature without heat exchange.

  When the cooling operation is performed in the refrigeration circuit 19, the four-way valve 18 connects the second port 18b and the third port 18c to each other and connects the first port 18a and the fourth port 18d to each other. Therefore, high-temperature and high-pressure refrigerant is supplied to the outdoor heat exchanger 16 from the discharge pipe 15 b of the compressor 15. The refrigerant flows through the outdoor heat exchanger 16, the expansion valve 17, and the indoor heat exchanger 14 in order. The outdoor heat exchanger 16 radiates heat from the refrigerant to the outside air. The refrigerant is decompressed to a low pressure by the expansion valve 17. The decompressed refrigerant absorbs heat from the surrounding air in the indoor heat exchanger 14. Cold air is generated. The cold air is caused to flow into the indoor space by the action of the first blower fan 27.

Warm air is caused to flow into the indoor space by the action of the first blower fan 27. The refrigerant is decompressed to a low pressure by the expansion valve 17. The decompressed refrigerant absorbs heat from the surrounding air in the outdoor heat exchanger 16. Thereafter, the refrigerant returns to the compressor 15.

  FIG. 2 schematically shows the appearance of the indoor unit 12 according to an embodiment. The main unit 25 of the indoor unit 12 includes a structure 28. An outer panel 29 covers the structure 28. A first air outlet 31 is formed on the lower surface of the structure 28. The first air outlet 31 opens downward. The structure 28 can be fixed to a wall surface in the room, for example. The first air outlet 31 extends in a horizontal direction at the time of installation, and blows out cool air or warm air generated by the indoor heat exchanger 14.

  A pair of front and rear wind direction plates 32 a and 32 b are arranged at the first outlet 31. The up-and-down wind direction plates 32a and 32b can rotate about horizontal axis lines 33a and 33b, respectively. In the present embodiment, the rear ends of the up and down wind direction plates 32a and 32b serve as the rotation shaft, but the present invention is not limited to this. Depending on the rotation, the up and down wind direction plates 32 a and 32 b can open and close the first outlet 31.

  As shown in FIG. 3, a first suction port 34 is formed in the structure 28. The first suction port 34 opens at the front and top surfaces of the structure 28. The outer panel 29 can be covered with the first suction port 34 in front of the structure 28. The first suction port 34 introduces indoor air toward the indoor heat exchanger 14.

  The fan units 26 are individually attached to both sides of the first inlet 34 and the first outlet 31 extending in the horizontal direction. The fan unit 26 is disposed outside the outer wall surface of the structure 28. Each fan unit 26 is accommodated in an auxiliary housing, that is, a fan housing 35. The fan housing 35 is supported on the outer wall surface of the structure 28 so as to be movable with respect to the structure 28. Here, the fan housing 35 can rotate around a rotation axis that intersects the outer wall surface of the structure 28. In the present embodiment, the rotation axis of the fan housing 35 overlaps the horizontal axis 36. The horizontal axes 33a, 33b, and 36 extend in parallel to each other. The outer wall surfaces of the structures 28 extend in parallel to each other. Therefore, the outer wall surfaces provided at both ends of the structure 28 are orthogonal to the horizontal axes 33a, 33b, 36.

  A second suction port 37 is formed in the fan housing 35. The second suction port 37 takes in room air from the vertical direction of the outer wall surface of the structure 28. The second suction port 37 is covered with a suction port cover 38. The suction port cover 38 is attached to the fan housing 35. The outline of the suction port cover 38 is defined along the virtual cylindrical surface 39 inside the virtual cylindrical surface 39 coaxial with the horizontal axis 36. That is, the suction port cover 38 has a circular outline. A plurality of openings 41 are formed in the suction port cover 38. The opening 41 connects the space inside and outside the second suction port 37 to each other.

  A second air outlet 42 is formed in the fan housing 35. The second air outlet 42 blows out room air taken into the fan housing 35 from the second air inlet 37. The airflow blows out from the second outlet 42 in a direction along the outer wall surface. When the fan housing 35 rotates around the horizontal axis 36, the second outlet 42 can be displaced up and down in the direction of gravity. The direction of the airflow blown out from the second air outlet 42 can be changed. Here, the forward direction side is referred to as “downstream” and the reverse direction side is referred to as “upstream” in accordance with the direction of rotation of the fan housing 35 that lowers the second outlet 42 in the direction of gravity. A wind direction plate 43 (hereinafter referred to as “fan unit wind direction plate 43”) is attached to the second outlet 42. The fan unit wind direction plate 43 can deflect the direction of the airflow blown out from the second air outlet 42 in the horizontal direction. The total opening area of the two second outlets 42 is smaller than the opening area of the first outlet 31.

  The structure for changing the posture of the fan housing 35 is not limited to this. For example, a wind direction plate that changes the wind direction in the vertical direction is provided at the second air outlet 42, and the fan housing 35 can swing around an axis extending in the vertical direction on the back side of the fan housing 35 on the outer wall surface of the structure 28. The orientation of the second outlet 42 may be changed in the horizontal direction. In addition, a wind direction plate that changes the wind direction in the left-right direction may be provided at the second air outlet 42, and the fan housing 35 may be moved up and down by a guide rail provided on the outer wall surface of the structure 28.

  The structure 28 includes an auxiliary structure 44. The auxiliary structure 44 is formed on the outer wall surface around the fan housing 35. The auxiliary structure 44 protrudes outward from the fan housing 35 from the outer wall surface. The edge of the auxiliary structure 44 is partitioned along the suction port cover 38 outside the virtual cylindrical surface 39 described above.

  As shown in FIG. 4, the first blower fan 27 is rotatably supported on the structure 28. For example, a cross flow fan can be used as the first blower fan 27. The first blower fan 27 can rotate around a rotation axis 45 parallel to the horizontal axis 36. The rotation shaft 45 of the first blower fan 27 extends in the horizontal direction when installed. Thus, the first blower fan 27 is arranged in parallel with the first blower outlet 31. The indoor heat exchanger 14 is disposed around the first blower fan 27.

  A first blower fan drive source 46 is fixed to the structure 28. For example, an electric motor can be used as the first blower fan drive source 46. The drive shaft of the first blower fan drive source 46 rotates about its axis. The drive shaft can be disposed coaxially with the rotation shaft 45 of the first blower fan 27. The drive shaft of the first blower fan drive source 46 can be coupled to the rotary shaft of the first blower fan 27. Thus, the driving force of the first blower fan drive source 46 is transmitted to the first blower fan 27. The first blower fan drive source 46 drives the first blower fan 27. The airflow passes through the indoor heat exchanger 14 according to the rotation of the first blower fan 27. As a result, a cold or warm air stream is generated. Cold air or warm air is blown out from the first outlet 31.

  As shown in FIG. 5, the structure 28 includes a main body 51, a front panel 52, a first side panel 53a, and a second side panel 53b. A first air outlet 31 is formed in the main body 51. A first side panel 53 a and a second side panel 53 b are attached to the main body 51 on both sides of the first outlet 31. The first side panel 53 a and the second side panel 53 b constitute an outer shell of the structure 28. Since the 1st side panel 53a and the 2nd side panel 53b are comprised by the right-and-left symmetrical similar components, below, the code | symbol is unified and demonstrated about the same components. The first side panel 53 a and the second side panel 53 b each have a wall body 54. Each wall 54 is provided on both sides of the main body 51 so as to be parallel to each other. The outer wall surface 54 a of the wall body 54 corresponds to the outer wall surface of the structure 28. Here, the outer wall surface 54 a may be orthogonal to the horizontal axis 36. The wall body 54 is fixed to the first air outlet 31 on both sides of the first air outlet 31. The auxiliary structures 44 are integrated with the first side panel 53a and the second side panel 53b, respectively. Such a member can be formed based on integral molding from a hard resin material. Similarly, the second side panel 53b and the auxiliary structure 44 can constitute one member. In the present embodiment, the first side panel 53a and the auxiliary structure 44, the second side panel 53b, and the auxiliary structure 44 are constituted by one member, but they may be constituted by different members.

  Screws 55 are used to attach the first side panel 53a and the second side panel 53b to the structure 28. The screw 55 passes through the first side panel 53a and the second side panel 53b and is screwed into the main body 51. When the screw 55 is screwed, a virtual plane 56 is defined. The virtual plane 56 is formed so as to connect the first side panel 53a and the second side panel 53b to each other. The axis of the screw 55 is orthogonal to the virtual plane 56. The virtual plane 56 faces the front of the structure 28. Here, the virtual plane 56 is parallel to the horizontal axis 36 and parallel to the wall surface of the room when the indoor unit 12 is installed, and is positioned on the front side of the first side panel 53a and the second side panel 53b. To do. The virtual plane 56 extends in parallel to the rotation axis 45 of the first blower fan 27.

  The main body 51 has a screw boss 57. The first side panel 53 a and the second side panel 53 b have screw insertion pieces 58. The screw insertion piece 58 has, for example, a plate piece having a uniform plate thickness at least partially. The plate piece of the screw insertion piece 58 is overlaid on the boss 57. The screw 55 passes through the screw insertion piece 58 and is screwed into the boss 57.

  A first electrical component unit 61 and a second electrical component unit 62 are attached to the front surface of the main body 51. A first control board is accommodated in the first electrical component unit 61. A second control board is accommodated in the second electrical component unit 62. When the front panel 52 is fixed to the main body 51, the first electrical component unit 61 and the second electrical component unit 62 are covered with the front panel 52.

  As shown in FIG. 6, each fan unit 26 includes a first decorative housing 71a and a second decorative housing 71b. The fan casing 35 includes a first decorative casing 71a and a second decorative casing 71b. The 1st decorative housing 71a and the 2nd decorative housing 71b are mutually connected, and the 2nd blower outlet 42 is formed. A second suction port 37 is defined in the first decorative housing 71a. In the internal space defined by the first decorative casing 71a and the second decorative casing 71b, there is a blower path unit 72, a centrifugal fan 73 as a second blower fan, a mounting plate 74, a second blower fan drive source 75, and a protective member. 76 is accommodated.

  The fan unit 26 includes an air passage unit 72. The air duct unit 72 includes a first member 72a and a second member 72b. The first member 72a of the air duct unit 72 is coupled to the second decorative casing 71b. In this way, the air duct unit 72 is integrated with the fan housing 35. A cylindrical portion 77 is formed on the first member 72 a of the air duct unit 72. The cylindrical portion 77 forms a cylindrical surface 77a coaxial with the horizontal axis 36 on the inner surface. The air passage unit 72 forms an opening 78 that communicates with the second suction port 37 and an air passage 79 that extends to the second air outlet 42.

  The fan unit 26 includes a centrifugal fan 73. The centrifugal fan 73 is accommodated in the air duct unit 72. As the centrifugal fan 73, for example, a sirocco fan can be used. The rotational axis of the centrifugal fan 73 intersects the outer wall surface 54 a of the wall body 54. Here, the rotational axis of the centrifugal fan 73 is orthogonal to the outer wall surface 54a. The rotational axis of the centrifugal fan 73 can overlap the horizontal axis 36. When the centrifugal fan 73 rotates, room air is taken in from the opening 78 along the rotation axis of the centrifugal fan 73. The centrifugal fan 73 pushes indoor air in the centrifugal direction over the entire circumference. The indoor air thus pushed out is blown out from the second air outlet 42 through the air blowing path 79.

  The fan unit 26 includes a mounting plate 74. The mounting plate 74 is connected to the first member 72a of the air duct unit 72, as will be described later. The first decorative casing 71a, the second decorative casing 71b, and the mounting plate 74 constitute the external appearance of the fan unit 26. The mounting plate 74 is overlaid on the outer wall surface 54 a of the wall body 54. The mounting plate 74 is screwed to the wall body 54. The screw 81 passes through the wall body 54 from the inner wall surface (the back side of the outer wall surface) of the wall body 54 and is screwed into the mounting plate 74. Each screw 81 can have an axis parallel to the horizontal axis 36. Thus, the fan unit 26 is fixed to the first side panel 53a and the second side panel 53b, respectively.

  The fan unit 26 includes a second blower fan drive source 75. The second blower fan drive source 75 is supported by the mounting plate 74. Since the mounting plate 74 is overlaid on the outer wall surface 54 a of the wall body 54, the second blower fan drive source 75 is fixed to the outer wall surface 54 a of the wall body 54 on both sides of the first outlet 31. The 2nd ventilation fan drive source 75 can be comprised with an electric motor, for example. The centrifugal fan 73 is fixed to the drive shaft 82 of the second blower fan drive source 75.

  The fan unit 26 includes a protection member 76. The protection member 76 is fixed to the mounting plate 74. The protection member 76 can be formed in a so-called dome shape. The protection member 76 covers the second blower fan drive source 75. The drive shaft 82 of the second blower fan drive source 75 penetrates the protection member 76 and protrudes from the side where the second blower fan drive source 75 is attached to the side where the centrifugal fan 73 of the protection member 76 is attached. A centrifugal fan 73 is attached to the drive shaft 82 of the second fan drive source 75 outside the protective member 76. The protection member 76 closes the opening of the cylindrical portion 77.

  The fan unit 26 includes a plurality of rollers 83. The rollers 83 are arranged at an equal distance from the horizontal axis 36. The roller 83 has a cylindrical body. The cylindrical body is rotatably supported by the protection member 76. The axis of the cylinder extends parallel to the horizontal axis 36. The roller 83 can rotate around the axis of the cylinder. The cylindrical body can be formed of a resin material such as POM (polyacetal resin). The cylindrical body is inscribed in the cylindrical surface 77 a of the air duct unit 72. Thus, the air duct unit 72 is connected to the protective member 76 through the rollers 83 so as to be rotatable around the horizontal axis 36.

  As shown in FIG. 7, a rack 84 is formed in the cylindrical portion 77 of the air duct unit 72. The rack 84 is disposed on the cylindrical surface 77 a at a position displaced from the roller 83 in the direction along the horizontal axis 36 and extends concentrically with the horizontal axis 36. A drive gear 85 meshes with the rack 84. The rotation axis of the drive gear 85 is set parallel to the horizontal axis 36. The cylindrical portion 77 can rotate with respect to the protection member 76 around the horizontal axis 36 in accordance with the rotation of the drive gear 85. That is, the air duct unit 72 can rotate. The rack 84 and the drive gear 85 constitute power transmission means.

  A fan housing drive source 86 is attached to the attachment plate 74. The fan housing drive source 86 can be constituted by an electric motor, for example. The drive shaft of the fan housing drive source 86 is connected to the drive gear 85. The axis of the drive shaft overlaps with the rotation shaft of the drive gear 85. Thus, the rotation of the drive gear 85 is caused based on the power of the fan housing drive source 86. The fan housing drive source 86 generates a driving force that causes the fan housing 35 to rotate. As described above, when the mounting plate 74 is overlaid on the outer wall surface 54 a of the wall body 54, the fan housing drive source 86 passes through the wall body 54 and is disposed inside the wall body 54. Thus, the fan housing drive source 86 is fixed to the inner wall surface of the wall body. In addition, the fan housing drive source 86 may be screwed to the inner wall surface of the wall body 54. In this case, the drive shaft of the fan housing drive source 86 only needs to penetrate the wall body 54. A screw used for fixing the fan housing drive source 86 may be screwed into the mounting plate 74 from the inner wall surface (the back side of the outer wall surface) of the wall member 54 through the wall member 54. The attachment plate 74 can be more firmly fixed in accordance with such joint fastening.

  As shown in FIG. 8, the fan unit 26 includes a drive unit 87 for the fan unit wind direction plate 43. The fan unit wind direction plate 43 can change its posture around the rotation axis 88 fixed to the first member 72 a of the air passage unit 72. The rotation axis 88 overlaps a tangent line that is in a virtual plane orthogonal to the horizontal axis line 36 and is in contact with a virtual circle concentric with the horizontal axis line 36. The drive unit 87 is accommodated in the fan housing 35 and is fixed to the air passage unit 72 on the upper side of the air passage 79.

  The drive unit 87 includes a link member 89. The link member 89 is connected to the fan unit wind direction plate 43. A link case 91 is fixed to the air passage unit 72 for connection. The link case 91 holds the upper end of the fan unit wind direction plate 43 so as to be rotatable around the rotation axis 88 of the fan unit wind direction plate 43. Connected to the upper end of the fan unit wind direction plate 43 is an eccentric shaft 92 that is eccentric from the rotation axis 88 of the fan unit wind direction plate 43 and extends parallel to the rotation axis 88 of the fan unit wind direction plate 43. A guide path 93 for the eccentric shaft 92 is formed in the link case 91. The guide path 93 of the eccentric shaft 92 guides the movement of the eccentric shaft 92 along an arc concentric with the rotation shaft 88 of the fan unit wind direction plate 43 when the fan unit wind direction plate 43 rotates.

  The drive unit 87 includes a left / right wind direction plate drive source 94. The left and right wind direction plate drive source 94 can be constituted by an electric motor, for example. The left and right wind direction plate drive source 94 is fixed to the air duct unit 72. The left / right wind direction plate drive source 94 has a drive shaft 94 a extending in parallel with the rotation shaft 88 of the fan unit wind direction plate 43. The upper end of the drive shaft 94a is rotatably held by the link case 91. An eccentric shaft 96 that is eccentric from the shaft center 95 of the drive shaft 94a and extends in parallel with the shaft center 95 of the drive shaft 94a is connected to the upper end of the drive shaft 94a. A guide path 97 for the eccentric shaft 96 is formed in the link case 91. The guide path 97 of the eccentric shaft 96 guides the movement of the eccentric shaft 96 along an arc concentric with the shaft center 95 of the drive shaft 94a.

  The link member 89 rotatably holds the eccentric shafts 92 and 96. When the eccentric shaft 96 moves in the guide path 97 according to the rotation of the left and right wind direction plate drive source 94, the movement of the eccentric shaft 96 causes the link member 89 to move. The link member 89 maintains its posture during the movement. The movement of the eccentric shaft 96 produces a movement of the eccentric shaft 92 along the same path. Thus, the posture of the fan unit wind direction plate 43 can be changed synchronously. The drive unit 87 generates a drive force that causes a change in the attitude of the fan unit wind direction plate 43.

  As shown in FIG. 9, the main body 51 includes a heat exchanger unit 101. The heat exchanger unit 101 includes an indoor heat exchanger 14 and a heat exchanger holder 102. A pair of heat exchanger holders 102 are coupled to both ends of the indoor heat exchanger 14 in the horizontal direction. The heat exchanger holder 102 is formed by resin molding, for example. The heat exchanger holder 102 is connected to an installation plate fixed to, for example, a wall surface. Thus, the indoor heat exchanger 14 is connected to, for example, an indoor wall surface at the time of installation. The heat exchanger holders 102 can be connected to each other by a connecting plate 103 made of resin.

  The main body 51 includes a main frame 104. The main frame 104 is disposed from one end to the other end of the heat exchanger unit 101, and the main frame 104 is coupled to the indoor heat exchanger 14. For coupling, the main frame 104 is fixed to the heat exchanger holder 102. Since the heat exchanger holder 102 supports the indoor heat exchanger 14 having a relatively large weight, the heat exchanger holder 102 has a relatively high rigidity structure. The boss 57 is formed on the main frame 104 by, for example, integral molding of resin. The boss 57 is formed with a receiving surface 105 extending in parallel with (or in contact with) the virtual plane 56. A plate piece of the screw insertion piece 58 of the first side panel 53a or the second side panel 53b is overlaid on the receiving surface 105. In this way, the relative position (and relative attitude) of the first side panel 53a and the second side panel 53b with respect to the indoor heat exchanger 14 can be determined. The receiving surface 105 is threaded. The screw 55 is screwed into the screw hole. Thus, the first side panel 53a and the second side panel 53b are attached to the main frame 104.

  In the present embodiment, the first side panel 53a and the second side panel 53b are attached to the main frame 104. However, for example, even if the structure is attached to the heat exchanger holder 102, the production line operation is simplified. Can achieve the effect.

  The main body 51 includes an outlet frame 107. The outlet frame 107 is coupled to the indoor heat exchanger 14. The air outlet frame 107 is fixed to the heat exchanger holder 102 for coupling. In this way, the fixing of the outlet frame 107 is stabilized. A first air outlet 31 is formed in the air outlet frame 107. The first blower fan 27 and the first blower fan drive source 46 are supported by the blower outlet frame 107.

  The first electrical component unit 61 and the second electrical component unit 62 are supported by the main frame 104, respectively. The first control board in the first electrical component unit 61 and the second control board in the second electrical component unit 62 include a power supply and control circuit for the first blower fan drive source 46 and a power supply for the second blower fan drive source 75. The control circuit, the power supply and control circuit of the fan housing drive source 86, the power supply and control circuit of the left and right wind direction plate drive source 94, and other electrical components are connected. Connections are appropriately distributed to the first control board and the second control board. For example, wiring can be used for connection.

  As shown in FIG. 10, the heat exchanger holder 102 includes a mounting plate 108. The mounting plate 108 extends in parallel to the rotation shaft 45 of the first blower fan 27. When the indoor unit 12 is installed, the mounting plate 108 spreads in the vertical direction and is stacked on the wall surface. A connecting plate 109 is integrated with the mounting plate 108. The connecting plate 109 extends along a plane orthogonal to the rotation axis 45 of the first blower fan 27. The connecting plate 109 is orthogonal to the wall surface and floor surface when the indoor unit 12 is installed. The connecting plate 109 is formed with a plurality of openings for receiving the hairpin portion 111 of the refrigerant tube. The refrigerant pipe of the indoor heat exchanger 14 is folded at the hairpin portion 111.

  A shielding plate 113 is formed on the outer edge of the connecting plate 109. The shielding plate 113 rises outward from the connecting plate 109. The hairpin portion 111 of the refrigerant pipe is accommodated in the space surrounded by the shielding plate 113. Therefore, the shielding plate 113 is disposed outside the connecting plate 109 below the hairpin portion 111 in the direction of gravity. Even when condensation occurs in the indoor heat exchanger 14 when the indoor unit 12 is installed and the water droplet falls in the direction of gravity, the dropped water droplet is received by the shielding plate 113. Water droplets are guided downward in the direction of gravity through the shielding plate 113.

  As shown in FIG. 11, the fan housing drive source 86 is arranged in a space outside the space located below the indoor heat exchanger 14 (here, the hairpin portion 111 of the refrigerant pipe) in the gravity direction when installed. Thus, if the fan housing drive source 86 is disposed at a position away from the lower side in the gravity direction of the indoor heat exchanger 14, the fan housing drive source 86 falls even if condensation occurs in the indoor heat exchanger 14. Do not immerse yourself in the incoming water droplets. The fan housing drive source 86 can be protected from condensation water. And since the 1st ventilation fan 27 is arrange | positioned inside the indoor heat exchanger 14, according to the air flow produced | generated by the 1st ventilation fan 27, air flows toward the inner side from the outer side of the indoor heat exchanger 14. FIG. . Such airflow acts to keep condensed water away from the fan housing drive source 86. As a result, the flooding of the fan housing drive source 86 can be avoided more reliably.

  Here, the fan housing drive source 86 extends from the virtual plane 114 extending in parallel to the inner wall surface of the wall body 54 and in contact with the side end of the indoor heat exchanger 14 (here, the front end of the hairpin portion 111) to the fan housing 35 side. It is arranged at a position shifted outward. However, as shown in FIG. 12, the fan housing drive source 86 extends from the virtual plane 114 that extends parallel to the inner wall surface of the wall body 54 and contacts the side end of the indoor heat exchanger 14 toward the indoor heat exchanger 14. It may be arranged at least partially at the position entering the inside. According to this, the indoor heat exchanger 14 and the fan housing drive source 86 overlap in a front view of the indoor unit 12. Thus, although the fan housing drive source 86 is disposed on the inner wall surface of the wall body 54, an increase in the size of the indoor unit 12 can be avoided.

  As shown in FIG. 13, the fan housing drive source 86 may be disposed in a space located below the indoor heat exchanger 14 in the direction of gravity when installed. When installed, the shielding plate 113 of the heat exchanger holder 102 is disposed below the indoor heat exchanger 14 in the direction of gravity and above the fan housing drive source 86 in the direction of gravity. Therefore, even if water drops fall according to the condensation of the indoor heat exchanger 14, the dropped water drops are blocked by the shielding plate 113. Even if the fan housing drive source 86 enters the space below the gravity direction of the indoor heat exchanger 14, the fan housing drive source 86 is not immersed in the falling water droplets. The fan housing drive source 86 can be reliably protected from dew condensation water. Moreover, since the shielding plate 113 is formed on the heat exchanger holder 104, an increase in the number of components can be avoided when the fan housing drive source 86 is shielded from water.

  Next, the operation of the air conditioner 11 will be described. For example, when the cooling operation is set, the four-way valve 18 connects the second port 18b and the third port 18c to each other and connects the first port 18a and the fourth port 18d to each other. The refrigerant circulates in the refrigeration circuit 19 according to the operation of the compressor 15. As a result, cold air is generated in the indoor heat exchanger 14. The temperature of the cold air is at least lower than the temperature of the room air. The operation of the compressor 15 is controlled according to the room temperature detected by the room temperature sensor. In addition, the compressor 15 may be stopped when, for example, the presence sensor is detected over a predetermined period by a human sensor.

  When the first blower fan 27 rotates, for example, as shown in FIG. 14, a cold airflow 121 blows out from the first outlet 31. At this time, the postures of the vertical wind direction plates 32a and 32b are appropriately controlled. The blowing of the airflow 121 can be controlled according to the direction of the up and down wind direction plates 32a and 32b. Here, the vertical airflow direction plates 32a and 32b are held in a substantially parallel posture with respect to the floor surface, so that the vertical airflow direction plates 32a and 32b are blown out from the first air outlet 31 so that the cold airflow 121 is blown in the horizontal direction. Be controlled.

  When the centrifugal fan 73 rotates, indoor air is sucked into the space inside the fan housing 35 from the second suction port 37 in the fan unit 26. The temperature of room air (hereinafter referred to as “room temperature air”) is equal to room temperature. The air flow of the sucked room temperature air blows out from the second outlet 42 of the fan unit 26. At this time, the attitude of the fan housing 35 is appropriately controlled around the horizontal axis 36. For example, as illustrated in FIG. 14, the posture of the fan housing 35 can change from a horizontal posture to a front downward (downstream direction). The fan housing 35 can guide the air flow 122 from the second air outlet 42 downward from the horizontal direction. The air flow 122 of room temperature air blows downward from the second blow-out port 42.

  Generally, the indoor unit 12 is installed at a relatively high position indoors. If the cool air flow 121 is guided in the horizontal direction, the cool air descends from a high position toward the floor surface. Cold air gradually accumulates indoors. At this time, the fan unit 26 can direct the air flow 122 of room temperature air directly to the occupant M. The fan unit 26 can function as a substitute for a so-called fan during cooling operation. Mixing of cold air can be prevented in the air flow 122 of room temperature air, and as a result, the occupant M can obtain a pleasant cool feeling. The occupant M can obtain a cool feeling based on the heat of vaporization generated by the air flow 122 in addition to the cool feeling based on the temperature drop in the room.

  For example, when the heating operation is set, the four-way valve 18 connects the second port 18b and the fourth port 18d to each other and connects the first port 18a and the third port 18c to each other. The refrigerant circulates in the refrigeration circuit 19 according to the operation of the compressor 15. As a result, warm air is generated in the indoor heat exchanger 14. The temperature of the warm air is at least higher than the temperature of the room air. The operation of the compressor 15 is controlled according to the room temperature detected by the room temperature sensor. For example, when the presence sensor is detected over a predetermined period by the human sensor, the compressor 15 may be stopped.

  As shown in FIG. 15, in the heating operation, the warm air flow 123 blows out from the first outlet 31 in accordance with the rotation of the first blower fan 27. At this time, the postures of the vertical wind direction plates 32a and 32b can be established downward. The up-and-down air direction plates 32a and 32b guide the airflow 123 from the first air outlet 31 downward toward the floor surface. The warm air flow 123 blows downward from the first outlet 31.

  Room temperature air is blown out from the second outlet 42 in accordance with the rotation of the centrifugal fan 73. Here, the posture of the fan housing 35 is set slightly upward (upstream direction) from the up-and-down airflow direction plates 32a and 32b. The fan housing 35 of the fan unit 26 establishes a posture in which the air flow 122 of room temperature air is blown downward from a position higher than the first air outlet 31 in the same manner as the vertical airflow direction plates 32a and 32b. The air flow 122 of the fan unit 26 forms a room temperature air layer above the warm air flow 123. The air flow 122 of room temperature air blown out from the second air outlet 42 can collide with the warm air flow and control the direction and movement of the warm air flow 123. Warm air can be sandwiched between the airflow 122 of the fan unit 26 and the floor surface. Thus, the rise in warm air is suppressed. Warm air is sent to the desired place indoors. Resident M can continue to feel warm under his feet. Since the room temperature is lower than the set temperature but reaches a specific temperature, it can be avoided that the occupant M feels chilly based on the air flow 122 of room temperature air. The indoor temperature environment is efficiently arranged.

  In such an air conditioner 11, cold air or warm air flow 121, 123 is blown out from the first outlet 31 of the main unit 25. The air flow 122 of room temperature air is blown out from the second outlet 42 of the fan unit 26. The airflow 122 of room temperature air and the airflows 121 and 123 of cold air or warm air have a temperature difference. Since the specific gravity of the air changes according to the temperature, the air flow 122 of room temperature air can control the direction and movement of the cold air and the warm air flow 121 and 123 according to the difference in specific gravity. Cold air or warm air can be sent to a desired place indoors. Thus, the indoor temperature environment can be adjusted efficiently.

  Hereafter, the characteristic point of this invention at the time of manufacture is demonstrated. In the indoor unit 12, the power of the fan housing drive source 86 is transmitted to the fan housing 35 by the rack 84 and the drive gear 85. In response to the supply of power from the fan housing drive source 86, the fan housing 35 rotates around the horizontal axis 36. In this way, the direction of the air flow of room temperature air can be adjusted. Since the fan housing drive source 86 is fixed not to the movable side such as the fan housing 35 but to the fixed side called the wall body 54, the swing of the wiring of the fan housing driving source 35 is avoided when the fan housing 35 rotates. . Therefore, a situation such as disconnection of the wiring can be reliably prevented. In addition, since the fan housing drive source 86 is fixed to the inner wall surface of the wall body 54, the wiring of the fan housing drive source 86 does not need to pass through the wall body 54 and be drawn out to the main frame 104 side. The assembly work of the housing drive source 86 can be simplified.
