- the first auxiliary flap 40 while adopting a posture in which resistance becomes as low as possible with respect to the air that is blown out, adopts a posture in which it raises a little upward the air direction of the air blown out from the scroll air outflow passage 16b pointing a little downward from the horizontal.
- a second air direction shown in FIG. 6 is an air direction when creating an airflow along the wall to which the rear surface portion 11c of the air conditioning indoor unit 10 is attached.
- the second auxiliary flap 30, the first auxiliary flap 40, and the air direction adjustment member 50 that have been set to blow out the air in the second air direction generate an airflow heading in the direction of the rear surface portion 11c from the air outlet 27.

- the second auxiliary flap 30 and the first auxiliary flap 40 can also adopt the postures shown in FIG. 8(a) and FIG. 8(b) .
- the second auxiliary flap 30 and the first auxiliary flap 40 shown in FIG. 8(a) adopt postures in which the second auxiliary flap upper surface 31 contacts the first auxiliary flap lower surface 42.

- the second auxiliary flap 30 is stowed in the recess 16g located in front of the flow passage upper surface 16c.
- the front end 43 of the first auxiliary flap 40 moves upward a little from where it is in the first air direction, and the first auxiliary flap 40 adopts a posture in which it widens upward the airflow blown out from the air outlet 27.
- the front end 55 of the air direction adjustment member 50 moves downward a little from where it is in the first air direction, and the air direction adjustment member 50 adopts a posture in which it widens downward the airflow blown out from the air outlet 27.

- the rate at which the first auxiliary flap lower surface 42 at this time declines downward heading forward is larger than that of the first virtual plane PL1, so that the first auxiliary flap lower surface 42 is more down in front than the first virtual plane PL1.
- the front end 55 of the air direction adjustment member 50 moves downward a little from where it is in the first air direction, and the air direction adjustment member 50 adopts a posture in which it guides downward the airflow blown out from the air outlet 27. That is to say, the rate at which the air direction adjustment member upper surface 51 at this time descends downward heading forward is larger than that of the second virtual plane PL2, so that the air direction adjustment member upper surface 51 is more down in front than the second virtual plane PL2.
- a fifth air direction shown in FIG. 9(c) is an example of an air direction when blowing out air forward and downward using the second auxiliary flap 30.
- the second auxiliary flap 30 rotates in such a way that the front end 33 moves downward, and the second auxiliary flap 30 sticks out from the recess 16g and adopts a down-in-front posture.
- the second auxiliary flap lower surface 32 is in a position near a plane joining the flow passage upper surface 16c and the first auxiliary flap lower surface 42 and relays the blown-out air in such a way that the airflow heading from the flow passage upper surface 16c toward the first auxiliary flap lower surface 42 becomes smooth.
- the front end 43 of the first auxiliary flap 40 is moved downward a little from where it is in the first air direction but is moved upward a little from where it is in the fourth air direction, and the first auxiliary flap 40 adopts a posture in which it pushes a little downward the airflow blown out from the air outlet 27. Furthermore, in the fifth air direction, the posture of the air direction adjustment member 50 is the same as it is in the fourth air direction. Because the second auxiliary flap 30, the first auxiliary flap 40, and the air direction adjustment member 50 adopt such postures, the air that has been blown out can be carried to a place farther away in front than in the fourth air direction.
- the position of the front end 33 of the second auxiliary flap 30 shown in FIG. 6 , FIG. 7 , FIG. 8(a), and FIG. 8(b) is lower than the rotational center 45 of the first auxiliary flap 40.
- the position of the second auxiliary flap 30 when it is stowed in the recess 16g is higher than the rotational center 45 of the first auxiliary flap 40.
- the first auxiliary flap 40 in the position shown in FIG. 6 to FIG. 8(b) on the path on which the second auxiliary flap 30 rotates gets in the way as the second auxiliary flap 30 rotates to the position of the second auxiliary flap 30 shown in FIG. 6 to FIG. 8(b) . That is to say, if the first auxiliary flap 40 were in the position shown in FIG.
- the front end 33 of the second auxiliary flap 30 can switch between a state in which it is higher than the rotational center 45 of the first auxiliary flap 40 and a state in which it is lower than the rotational center 45 of the first auxiliary flap 40.
- FIG. 10(a) shows an end surface of the air direction adjustment member 50 cut by line I-I of FIG. 3 .
- FIG. 10(b) shows a side surface of the air direction adjustment member 50 as seen from the right side.
- FIG. 11 shows a state in which the air direction adjustment member 50 is broken out at its central part and seen from the right and above.
- the air direction adjustment member 50 has a hollow structure where a plate-like member configuring the air direction adjustment member upper surface 51 and a plate-like member configuring the air direction adjustment member lower surface 52 are fused together. Because the air direction adjustment member 50 has a hollow structure, this leads to deformation of the air direction adjustment member 50 if a concentration of stress occurs in the air direction adjustment member upper surface 51 and the air direction adjustment member lower surface 52. If the air direction adjustment member 50 deforms, a large gap forms between the air direction adjustment member 50 and the casing 11 when operation is stopped, for example, and the visual attractiveness is reduced.
- a supported portion 53 is provided in a recess portion 60 in a central pivotally supported part of the air direction adjustment member 50.
- the supported portion 53 in the central pivotally supported part is rotatably supported by a support portion 71 that bridges the upper edge 27a and the lower edge 27b of the air outlet 27 of the casing 11.
- flanges 59 greater in width than the thickness of the air direction adjustment member 50 are attached to a right end portion 61 and a left end portion 62 of the air direction adjustment member 50 (see FIG. 3 ).
- supported portions 53 are provided on the flanges 59.
- the supported portions 53 on the flanges 59 are rotatably fitted into support portions (not shown in the drawings) provided in the casing 11.
- the air conditioning indoor unit 10 generates an airflow that flows along the installation side wall WL, and this airflow will be called a first airflow CL1.
- the air direction adjustment member 50 adopts a posture in which the air direction adjustment member upper surface 51 rotates rearward relative to a vertical plane so that the front end 55 of the air direction adjustment member 50 is positioned more rearward than the rear end 56, and this posture will be called a first posture.
- the air conditioning indoor unit 10 generates an airflow that heads forward from the air outlet 27, and this airflow will be called a second airflow CL2.
- the air direction adjustment member 50 adopts a posture in which the air direction adjustment member upper surface 51 rotates forward relative to a vertical plane so that the front end 55 of the air direction adjustment member 50 is positioned more forward than the rear end 56, and this posture will be called a second posture.
- FIG. 14 shows an enlarged view of the area around the lower edge 27b of the air outlet 27 in a state in which the air direction adjustment member 50 is adopting the first posture.
- a recessed portion 57 is formed by a step in the air direction adjustment member lower surface 52.
- the front side of the air direction adjustment member lower surface 52 describes a curved line that is convex downward, while the rear side describes a curved line that is convex upward.
- the rear side of the air direction adjustment member lower surface 52 that describes a curved line that is convex upward is recessed upward to form a step, and this upwardly recessed step part is the recessed portion 57.
- the air direction adjustment member 50 is attached in such a way that, at the time of the second air direction in which the air direction adjustment member 50 adopts the first posture, the lower edge 27b of the air outlet 27 enters the recessed portion 57 formed in the air direction adjustment member lower surface 52. Consequently, compared to a case where there is no recessed portion 57 in the air direction adjustment member lower surface 52, the front end 55 of the air direction adjustment member 50 can be moved further rearward by how much the lower edge 27b enters the recessed portion 57. As a result, compared to a case where there is no recessed portion 57, the airflow can be made to flow along the installation side wall WL from a higher position because there is the recessed portion 57.
- a depression portion 72 that is set rearward is formed and groove portions 73 that are recessed rearward are formed.
- the front end 55 of the air direction adjustment member 50 can be moved further rearward because the depression portion 72 is formed.
- the air direction adjustment member 50 can adopt a posture in which the air direction adjustment member upper surface 51 is rotated rearward relative to a vertical plane.
- the air direction adjustment member 50 can adopt the first posture in which it allows the airflow to flow along the installation side wall WL from a higher position compared to a case where the depression portion 72 is not formed.
- a gap forms between the lower edge 27b and the air direction adjustment member lower surface 52.
- the groove portions 73 fulfill the role of disrupting the airflow that arises in this gap. The airflow that arises in the gap is disrupted and the air is agitated, whereby it becomes difficult for condensation to form.
- a recessed portion 57 is formed by a step in the air direction adjustment member lower surface 52, but as with a sloping end surface 57A of an air direction adjustment member 50A shown in FIG. 15 and FIG. 16 , a recessed portion can also be formed by the sloping end surface 57A.
- the front side of an air direction adjustment member lower surface 52A describes a gentle curved line that is convex downward, while the rear side describes a straight line with a large inclination. Because of the structure of this air direction adjustment member lower surface 52A, a recessed portion is formed by the sloping end surface 57A on the rear side of the air direction adjustment member lower surface 52A.
- a sloping end surface 74 is also formed in the lower edge 27b of the air outlet 27, which opposes the sloping end surface 57A serving as a recessed portion when the air direction adjustment member 50A adopts the first posture. It is preferred that the sloping end surface 57A serving as a recessed portion and the sloping end surface 74 of the lower edge 27b be configured to become parallel to each other when the air direction adjustment member 50A has rotated rearward so that the front end 55 has moved rearward its maximum extent. It will be noted that the groove portions 73 described in the embodiment may also be formed in the sloping end surface of the lower edge 27b.
- the lower edge 27b of the air outlet 27 enters the recessed part of the recessed portion 57 or the sloping end surface 57A serving as a recessed portion of the air direction adjustment member 50 or 50A when the air direction adjustment member 50 or 50A adopts the first posture.

- the range of rotational motion can be increased, so restrictions on airflow control for ensuring comfort can be eased. Furthermore, in the air conditioning indoor unit 10, design attractiveness can be well maintained because the recessed portion 57 and the sloping end surface 57A serving as a recessed portion are formed in such a way that they are hardly noticeable in the air direction adjustment member lower surfaces 52 and 52A.
- the planes indicated by the long dashed double-short dashed lines are formed by extending the front/rear planes of the recessed portion 57 or the sloping end surface 57A serving as a recessed portion, for example.
- the depression portion 72 corresponding to the shape of the air direction adjustment member lower surface 52 is formed in the lower edge 27b of the air outlet 27 and in a position opposing the rear end portion of the air direction adjustment member lower surface 52 of the air direction adjustment member 50 that has adopted the first posture. Because the depression portion 72 is provided in correspondence to the shape of the air direction adjustment member lower surface 52, the range of rearward rotation of the air direction adjustment member 50 can be increased compared to a case where the depression portion 72 is not provided. As a result, restrictions on the airflow control of the air conditioning indoor unit 10 can be eased by how much the rotational range is increased.
- the groove portions 73 provided in the lower edge 27b of the air outlet 27 of the casing 11 are formed opposing the gap between the air direction adjustment member 50 and the casing 11. As a result, the air that flows through the gap between the air direction adjustment member 50 and the casing 11 can be agitated, and the groove portions 73 can keep condensation from forming in the gap between the air direction adjustment member 50A and the casing 11.
- the sloping end surface 57A serving as a recessed portion of the air direction adjustment member 50A and the sloping end surface 74 of the casing 11 oppose each other when the air direction adjustment member 50A adopts the first posture, so the range of rearward rotation of the air direction adjustment member 50A can be increased.

- It is a problem of the present invention to ease restrictions on airflow control in a wall-mounted air conditioning indoor unit.
- A wall-mounted air conditioning indoor unit pertaining to a first aspect of the invention comprises: a casing having rear surface portion is secured to an installation side wall and having an air outlet, through which conditioned air is blown out, located in front of the rear surface portion; and an air direction adjustment member that has a rear end near, a front end arranged at position farther from a rotational center set at a lower edge (27) than the rear end, an upper surface that adjusts the air direction of outlet air blown out from the air outlet, and a lower surface located on the opposite side of the upper surface, the air direction adjustment member having a recessed portion that is upwardly recessed being disposed in a rear end portion of the lower surface, wherein the air direction adjustment member is configured to be capable of being located in a first posture, in which the front end is positioned more rearward than the rear end by rearward rotation beyond a vertical plane of the upper surface so that when generating a first airflow toward the installation side wall from the air outlet, and a second posture, in which the front end is positioned more forward than the rear end by forward rotation beyond the vertical plane of the upper surface when generating a second airflow forward from the air outlet, and the air direction adjustment member is attached in such a way that the lower edge of the air outlet enters the recessed portion when the air direction adjustment member becomes the first posture.
- In this wall-mounted air conditioning indoor unit, the lower edge of the air outlet enters the recessed part of the recessed portion of the air direction adjustment member when the air direction adjustment member becomes the first posture, so the range of rotational motion can be increased.
- A wall-mounted air conditioning indoor unit pertaining to a second aspect of the invention is the air conditioning indoor unit pertaining to the first aspect, wherein the casing has a depression portion corresponding to the shape of the lower surface of the air direction adjustment member disposed in the lower edge of the air outlet and in a position opposing the rear end portion of the lower surface of the air direction adjustment member that has become the first posture.
- In this wall-mounted air conditioning indoor unit, the depression portion provided on the lower edge of the air outlet of the casing is provided in correspondence to the shape of the lower surface of the air direction adjustment member, so the range of rearward rotation of the air direction adjustment member can be increased compared to a case where the depression portion is not provided.
- A wall-mounted air conditioning indoor unit pertaining to a third aspect of the invention is the air conditioning indoor unit pertaining to the first aspect or the second aspect, wherein the casing has groove portions disposed in the lower edge of the air outlet and in a position opposing the rear end portion of the lower surface of the air direction adjustment member that has become the first posture.
- In this wall-mounted air conditioning indoor unit, the groove portions provided in the lower edge of the air outlet of the casing are disposed opposing a gap between the air direction adjustment member and the casing, so air flowing through the gap between the air direction adjustment member and the casing can be agitated.
- A wall-mounted air conditioning indoor unit pertaining to a fourth aspect of the invention is the air conditioning indoor unit pertaining to the first aspect, wherein sloping end surfaces are formed in the air direction adjustment member and in the casing in places thereof that oppose each other when the air direction adjustment member adopts the first posture.

FIG. 1 shows the outer appearance of an air conditioningindoor unit 10 as seen from the front and obliquely from the right and below. The up and down, front and rear, and right and left directions of the air conditioningindoor unit 10 in the following description are as indicated by the Cartesian coordinates inFIG. 1 .FIG. 2 shows the main shape of the cross section of the air conditioningindoor unit 10 cut by a plane perpendicular to the right and left direction of the air conditioningindoor unit 10 in the substantial center of the air conditioningindoor unit 10 in the right and left direction. The air conditioningindoor unit 10 is a wall-mounted type, and its rear portion is attached to an installation side wall WL in a room. The air conditioningindoor unit 10 can perform a cooling operation in which it performs cooling of a room space RS and a heating operation in which it performs heating of the room space RS. - As shown in
FIG. 1 andFIG. 2 , the air conditioningindoor unit 10 is equipped with acasing 11, anair filter 12, anindoor heat exchanger 13, anindoor fan 14, pluralvertical flaps 15, a secondauxiliary flap 30, a firstauxiliary flap 40, and an airdirection adjustment member 50. It will be noted that illustration of thevertical flaps 15 is omitted inFIG. 2 . - The
casing 11 is shaped like a box that is long and narrow in the transverse direction (the right and left direction of the air conditioning indoor unit 10 (refer to the Cartesian coordinates inFIG. 1 )) and has plural openings. Thecasing 11, as shown inFIG. 1 andFIG. 2 , has inside a three-dimensional space surrounded by atop surface portion 11a, afront surface portion 11b, arear surface portion 11c, a rightside surface portion 11d, a leftside surface portion 11e, and abottom surface portion 11f. Thetop surface portion 11a, thefront surface portion 11b, the rightside surface portion 11d, the leftside surface portion 11e, and thebottom surface portion 11f of thecasing 11 are covered by adecorative plate 20. Thecasing 11 is attached to the installation side wall WL by means of aback surface plate 28 located on therear surface portion 11c. Theair filter 12, theindoor heat exchanger 13, theindoor fan 14, and abottom frame 16 are housed in the three-dimensional space in thecasing 11. In order to house these in the three-dimensional space, thedecorative plate 20 is configured to be overlaid from the front to the rear. - The
top surface portion 11a is positioned on the upper end portion of thecasing 11. Thefront surface portion 11b of thedecorative plate 20 is configured by a front surface plate 21 whose upper end is supported on thetop surface portion 11a by hinge (not shown in the drawings) in such a way that the front surface plate 21 may freely rotate. The front surface plate 21 is separated from aright side plate 22, which configures the rightside surface portion 11d of thedecorative plate 20, and aleft side plate 23, which configures the leftside surface portion 11e of thedecorative plate 20. - The
back surface plate 28 configures therear surface portion 11c of thecasing 11. The air conditioningindoor unit 10 is installed on the installation side wall WL by mounting, with screws or the like, theback surface plate 28 to a mounting plate (not shown in the drawings) installed on the installation side wall WL in the room. - A top
surface air inlet 25 is provided in thetop surface portion 11 a of thecasing 11. When theindoor fan 14 is driven, room air in the neighborhood of the topsurface air inlet 25 is taken inside thecasing 11 from the topsurface air inlet 25. The room air that has been taken in from the topsurface air inlet 25 travels through theindoor heat exchanger 13 and is sent to theindoor fan 14. - A bottom
surface air inlet 26 is formed in thebottom surface portion 11f of thecasing 11. Furthermore, anair outlet 27 is formed in thebottom surface portion 11f. The bottomsurface air inlet 26 is provided more rearward than theair outlet 27. The bottomsurface air inlet 26 and the space located above theair filter 12 in thecasing 11 are interconnected by aninflow passage 16a of thebottom frame 16. Consequently, because of the driving of theindoor fan 14, room air in the neighborhood of the bottomsurface air inlet 26 is sent from the bottomsurface air inlet 26 through theinflow passage 16a to theindoor heat exchanger 13. Theinflow passage 16a is formed along a flow passageupper surface 16c and a flow passagelower surface 16d of thebottom frame 16 from the bottomsurface air inlet 26. Theinflow passage 16a and a later-described scrollair outflow passage 16b are adjacent to each other across the flow passagelower surface 16d. An opening and closingplate 17 for opening and closing the bottomsurface air inlet 26 is provided in the bottomsurface air inlet 26. - In the air conditioning
indoor unit 10, theair outlet 27 provided more forward than the bottomsurface air inlet 26 is connected to the inside of thecasing 11 by the scrollair outflow passage 16b. Room air sucked in from the topsurface air inlet 25 and the bottomsurface air inlet 26 undergoes heat exchange in theindoor heat exchanger 13, thereafter travels through the scrollair outflow passage 16b, and is blown out into the room from theair outlet 27. - The
air outlet 27 has anupper edge 27a and alower edge 27b that extend long right and left. The flat plate-like secondauxiliary flap 30 that extends long right and left and the firstauxiliary flap 40 that extends long right and left are provided on the side of theupper edge 27a of theair outlet 27. Furthermore, the airdirection adjustment member 50 that extends long right and left is provided on the side of thelower edge 27b of theair outlet 27. The secondauxiliary flap 30, the firstauxiliary flap 40, and the airdirection adjustment member 50 respectively have a second auxiliary flapupper surface 31 and a second auxiliary flaplower surface 32, a first auxiliary flapupper surface 41 and a first auxiliary flaplower surface 42, and an air direction adjustment memberupper surface 51 and an air direction adjustment memberlower surface 52. The firstauxiliary flap 40 and the airdirection adjustment member 50 are hollow structures, whereby the weight of the firstauxiliary flap 40 and the airdirection adjustment member 50 is reduced. - The second
auxiliary flap 30, the firstauxiliary flap 40, and the airdirection adjustment member 50 are each rotatably attached to thecasing 11. The secondauxiliary flap 30, the firstauxiliary flap 40, and the airdirection adjustment member 50 are configured in such a way that they can be independently rotated, by flap drive motors (not shown in the drawings) provided with respect to each, aboutrotational centers FIG. 6 ) extending right and left.FIG. 3 shows a view of the airdirection adjustment member 50 as seen obliquely from the right and above. A straight line joining supportedportions 53 of the airdirection adjustment member 50 becomes therotational center 58 of the airdirection adjustment member 50. Furthermore, the flap drive motors are controlled by a control device (not shown in the drawings) provided inside the air conditioningindoor unit 10. Additionally, the secondauxiliary flap 30, the firstauxiliary flap 40, and the airdirection adjustment member 50 adjust up and down, by themselves or in cooperation with each other, the air direction of the air blown out from theair outlet 27. Furthermore, the airdirection adjustment member 50 has the function of opening theair outlet 27 when blowing out air from theair outlet 27 and closing theair outlet 27 when operation is stopped. Moreover, the firstauxiliary flap 40 is configured in such a way that, when operation is stopped, it can adopt a posture in which it moves closer to thecasing 11 and becomes like part of thecasing 11. When operation is stopped, the first auxiliary flaplower surface 42 and the air direction adjustment memberlower surface 52 become assimilated with thedecorative plate 20 of thecasing 11 and configure the design of the air conditioningindoor unit 10. - The plural
vertical flaps 15, which have flat surfaces intersecting the right and left direction, are provided on the far side of the secondauxiliary flap 30 in theair outlet 27. Thevertical flaps 15 are configured in such a way that they can be rotated right and left, by a flap drive motor (not shown in the drawings), about rotational centers extending up and down. The flap drive motor that drives thevertical flaps 15 is also controlled by the aforementioned control device provided inside the air conditioningindoor unit 10. Additionally, the pluralvertical flaps 15 adjust right and left the air direction of the air blown out from theair outlet 27. - The
indoor heat exchanger 13 is configured by plural fins and plural heat transfer tubes that run through the plural fins. Theindoor heat exchanger 13 is attached to thebottom frame 16 inside thecasing 11. Theindoor heat exchanger 13 functions as an evaporator or a condenser in accordance with the operating state of the air conditioningindoor unit 10, and causes heat exchange to be carried out between refrigerant flowing through the heat transfer tubes and the air traveling through theindoor heat exchanger 13. - The
indoor heat exchanger 13, as shown inFIG. 2 , has a substantially inverted V-shape in which both ends bend downward as seen in a side view. Additionally, theindoor heat exchanger 13 is disposed so as to surround theindoor fan 14 from above. - The
indoor fan 14, as shown inFIG. 2 , is positioned in the substantially central part of the inside of thecasing 11. Theindoor fan 14 is a cross-flow fan having a substantially cylindrical shape that is long and narrow in the longitudinal direction of the air conditioning indoor unit 10 (the right and left direction). When theindoor fan 14 is driven to rotate, conditioned air that has been generated as a result of the room air being sucked in from the topsurface air inlet 25 and the bottomsurface air inlet 26, traveling through theair filter 12, and then traveling through theindoor heat exchanger 13 is blown out into the room from theair outlet 27. - The
bottom frame 16 fulfills the role of supporting theaforementioned air filter 12, theindoor heat exchanger 13, and theindoor fan 14. Furthermore, theinflow passage 16a and the scrollair outflow passage 16b are formed by thebottom frame 16. The scrollair outflow passage 16b extends obliquely forward and downward from directly under theindoor fan 14. The scrollair outflow passage 16b is a space sandwiched between the flow passageupper surface 16c and the flow passagelower surface 16d. -
FIG. 4 shows a state in which the secondauxiliary flap 30, the firstauxiliary flap 40, and the airdirection adjustment member 50 have been removed fromFIG. 2 . The shape of the scrollair outflow passage 16b will be described usingFIG. 4 . The flow passagelower surface 16d extends upward from thelower edge 27b of theair outlet 27 and covers the rear portion of theindoor fan 14 up to its diagonal upper part. The flow passagelower surface 16d smoothly curves in such a way as to bulge rearward. The cross-sectional shape of the flow passagelower surface 16d when the flow passagelower surface 16d is cut by a plane perpendicular to the right and left direction is a spiral shape. In other words, the cross-sectional shape of the flow passagelower surface 16d is a curved line that moves further and further away from the rotational center of theindoor fan 14 as it spirals. - A
recess 16g that extends long right and left is formed between theupper edge 27a of theair outlet 27 and an upper surfacefront end 16f of the flow passageupper surface 16c. Because thisrecess 16g is formed, a step is formed in front of the upper surfacefront end 16f of the flow passageupper surface 16c. The secondauxiliary flap 30 can be stowed in therecess 16g. Therecess 16g is configured in such a way that, in a state in which the secondauxiliary flap 30 is stowed in therecess 16g, the rear end portion of the second auxiliary flaplower surface 32 becomes even with the flow passageupper surface 16c. The flow passageupper surface 16c extends substantially straightly obliquely rearward and upward from the upper surfacefront end 16f heading toward the lower part of theindoor fan 14. - The
air filter 12 is for trapping dirt and dust in the room air that has been sucked in from the topsurface air inlet 25 and the bottomsurface air inlet 26. In a state in which theair filter 12 is loaded in thecasing 11, theair filter 12 is positioned between thetop surface portion 11a of thecasing 11 and theindoor heat exchanger 13. Theair filter 12 prevents dirt and dust in the room air from sticking to the surface of theindoor heat exchanger 13. Theair filter 12 is configured in such a way that it can be put into thecasing 11 and removed from thecasing 11 for maintenance. - The postures of the second
auxiliary flap 30, the firstauxiliary flap 40 and the airdirection adjustment member 50 shown inFIG. 1 andFIG. 2 are adopted when blowing out air in a first air direction. The first air direction is an air direction when causing the airflow to circulate as far as the far side of the room space RS. In order to cause the airflow to circulate as far as the far side of the room space RS, it is preferred to create a laminar flow having a fast air speed without allowing the airflow to diffuse at theair outlet 27. To create such a laminar flow, it is preferred to extend the scrollair outflow passage 16b. However, it is difficult to extend and shorten the scrollair outflow passage 16b, so the state shown inFIG. 1 andFIG. 2 is a state in which the postures of the secondauxiliary flap 30 and the airdirection adjustment member 50 pseudo-create a situation that is the same as if the scrollair outflow passage 16b were extended. - In the first air direction, the second
auxiliary flap 30 adopts a posture in which the second auxiliary flaplower surface 32 extends forward the flow passageupper surface 16c of the scrollair outflow passage 16b. Furthermore, in the first air direction, the airdirection adjustment member 50 adopts a posture in which the air direction adjustment memberupper surface 51 extends forward the flow passagelower surface 16d of the scrollair outflow passage 16b. - As shown in
FIG. 4 , when the flow passageupper surface 16c is extended forward, a first virtual plane PL1 that starts at the upper surfacefront end 16f is formed substantially parallel to the flow passageupper surface 16c. In this case, it is preferred that a first virtual line formed as a result of the first virtual plane PL1 being cut by a sectional plane parallel to the rear direction and the up and down direction coincide with a tangent to the distal end portion of the flow passageupper surface 16c of the scrollair outflow passage 16b. Furthermore, when the flow passagelower surface 16d is extended forward, a second virtual plane PL2 that starts at a lower surfacefront end 16h of the flow passagelower surface 16d is formed substantially parallel to the lower surfacefront end 16h. In this case, it is preferred that a second virtual line formed as a result of the second virtual plane PL2 being cut by a sectional plane parallel to the front and rear direction and the up and down direction coincide with a tangent to the distal end portion of the flow passagelower surface 16d of the scrollair outflow passage 16b. - It will be noted that there are also cases where the second auxiliary flap
lower surface 32 curves a little, and in those cases the second auxiliary flaplower surface 32 is regarded as coinciding with the first virtual plane PL1 when the rear end portion of the main surface of the second auxiliary flaplower surface 32 coincides with the first virtual plane PL1. Furthermore, there are also cases where the second auxiliary flaplower surface 32 curves a little, and in those cases the air direction adjustment memberupper surface 51 is regarded as coinciding with the second virtual plane PL2 when the rear end portion of the main surface of the air direction adjustment memberupper surface 51 coincides with the second virtual plane PL2. It will be noted that "main surface" here refers to the surface used exclusively for air direction adjustment, excluding parts that do not contribute to air direction adjustment. For example, arecess portion 54 is provided in correspondence to a projection located in thecasing 11. This part with therecess portion 54 is a structure for ensuring that the projection of thecasing 11 does not get in the way when the airdirection adjustment member 50 closes theair outlet 27, and is not included in the main surface because it does not contribute much to air direction adjustment. - The second
auxiliary flap 30 is, for the purpose of rotating, attached away from the upper surfacefront end 16f of the flow passageupper surface 16c. For the same reason, the airdirection adjustment member 50 is also attached away from the lower surfacefront end 16h of the flow passagelower surface 16d. However, if the secondauxiliary flap 30 is too far away from the flow passageupper surface 16c and the airdirection adjustment member 50 is too far away from the flow passagelower surface 16d, a sufficient effect of extending the scrollair outflow passage 16b by means of the second auxiliary flaplower surface 32 and the airdirection adjustment member 50 is not obtained. Therefore, in a state in which the secondauxiliary flap 30 and the airdirection adjustment member 50 are set to the first air direction, in the range in which the secondauxiliary flap 30 is rotatable the distance from a rear end 34 (seeFIG. 2 ) of the secondauxiliary flap 30 to the upper surfacefront end 16f of the flow passageupper surface 16c is configured to be equal to or less than 5 mm, and a distance L1 from arear end 56 of the airdirection adjustment member 50 to the lower surfacefront end 16h of the flow passagelower surface 16d is configured to be equal to or less than 5 mm (seeFIG. 5 ). - The first
auxiliary flap 40, because it is provided downstream of the secondauxiliary flap 30, finely adjusts up and down the air direction of the air blown out from that part surrounded by afront end 33 of the secondauxiliary flap 30 and afront end 55 of the airdirection adjustment member 50, which are the air outlet of the extended scrollair outflow passage 16b. In the state shown inFIG. 2 , the firstauxiliary flap 40, while adopting a posture in which resistance becomes as low as possible with respect to the air that is blown out, adopts a posture in which it raises a little upward the air direction of the air blown out from the scrollair outflow passage 16b pointing a little downward from the horizontal. - A second air direction shown in
FIG. 6 is an air direction when creating an airflow along the wall to which therear surface portion 11c of the air conditioningindoor unit 10 is attached. The secondauxiliary flap 30, the firstauxiliary flap 40, and the airdirection adjustment member 50 that have been set to blow out the air in the second air direction generate an airflow heading in the direction of therear surface portion 11c from theair outlet 27. At this time, the air direction adjustment memberupper surface 51 of the airdirection adjustment member 50 rotates rearward beyond a vertical plane perpendicular to the front and rear direction, so that thefront end 55 of the airdirection adjustment member 50 is positioned more rearward than therear end 56 of the airdirection adjustment member 50. Similarly, the first auxiliary flapupper surface 41 of the firstauxiliary flap 40 also rotates rearward beyond a vertical plane perpendicular to the front and rear direction, so that afront end 43 of the firstauxiliary flap 40 is positioned more rearward than a rear end 44 (seeFIG. 2 ) of the firstauxiliary flap 40. Similarly, the second auxiliary flapupper surface 31 of the secondauxiliary flap 30 also rotates rearward beyond a vertical plane perpendicular to the front and rear direction, so that thefront end 33 of the secondaryauxiliary flap 30 is positioned more rearward than the rear end 34 (seeFIG. 2 ) of the secondauxiliary flap 31. - The second
auxiliary flap 30 and the firstauxiliary flap 40 at the time of the second air direction adopt postures in which they overlap each other as seen in a frontal view, whereby the secondauxiliary flap 30 and the firstauxiliary flap 40 prevent the air from flowing forward through a gap between the secondauxiliary flap 30 and the firstauxiliary flap 40. - As the second air direction, the second
auxiliary flap 30 and the firstauxiliary flap 40 can also adopt the postures shown inFIG. 8(a) and FIG. 8(b) . The secondauxiliary flap 30 and the firstauxiliary flap 40 shown inFIG. 8(a) adopt postures in which the second auxiliary flapupper surface 31 contacts the first auxiliary flaplower surface 42. Furthermore, the secondauxiliary flap 30 and the firstauxiliary flap 40 shown inFIG. 8(b) adopt postures in which thefront end 33 of the secondauxiliary flap 30 is contiguous with the firstauxiliary flap 40 and in which the second auxiliary flaplower surface 32 and the first auxiliary flaplower surface 42 are side by side in a row and continuous with each other. - A third air direction shown in
FIG. 9(a) is an air direction when blowing out air at a maximum air volume. When the air conditioningindoor unit 10 has been set to blow out the air in the third air direction, the secondauxiliary flap 30 is stowed in therecess 16g located in front of the flow passageupper surface 16c. In the third air direction, thefront end 43 of the firstauxiliary flap 40 moves upward a little from where it is in the first air direction, and the firstauxiliary flap 40 adopts a posture in which it widens upward the airflow blown out from theair outlet 27. In the third air direction, thefront end 55 of the airdirection adjustment member 50 moves downward a little from where it is in the first air direction, and the airdirection adjustment member 50 adopts a posture in which it widens downward the airflow blown out from theair outlet 27. That is to say, the firstauxiliary flap 40 and the airdirection adjustment member 50 adopt postures in which they become farther apart heading forward and in which it is easy for them to deliver to the room space RS the air that has been blown out at the maximum air volume. - A fourth air direction shown in
FIG. 9(b) is an air direction when blowing out air forward and downward. When the air conditioningindoor unit 10 has been set to blow out the air in the fourth air direction, the secondauxiliary flap 30 is stowed in therecess 16g located in front of the flow passageupper surface 16c. In the fourth air direction, thefront end 43 of the firstauxiliary flap 40 moves downward a little from where it is in the first air direction, and the firstauxiliary flap 40 adopts a posture in which it pushes downward the airflow blown out from theair outlet 27. That is to say, the rate at which the first auxiliary flaplower surface 42 at this time declines downward heading forward is larger than that of the first virtual plane PL1, so that the first auxiliary flaplower surface 42 is more down in front than the first virtual plane PL1. In the fourth air direction, thefront end 55 of the airdirection adjustment member 50 moves downward a little from where it is in the first air direction, and the airdirection adjustment member 50 adopts a posture in which it guides downward the airflow blown out from theair outlet 27. That is to say, the rate at which the air direction adjustment memberupper surface 51 at this time descends downward heading forward is larger than that of the second virtual plane PL2, so that the air direction adjustment memberupper surface 51 is more down in front than the second virtual plane PL2. - A fifth air direction shown in
FIG. 9(c) is an example of an air direction when blowing out air forward and downward using the secondauxiliary flap 30. When the air conditioningindoor unit 10 has been set to blow out the air in the fifth air direction, the secondauxiliary flap 30 rotates in such a way that thefront end 33 moves downward, and the secondauxiliary flap 30 sticks out from therecess 16g and adopts a down-in-front posture. At this time, the second auxiliary flaplower surface 32 is in a position near a plane joining the flow passageupper surface 16c and the first auxiliary flaplower surface 42 and relays the blown-out air in such a way that the airflow heading from the flow passageupper surface 16c toward the first auxiliary flaplower surface 42 becomes smooth. - In the fifth air direction, the
front end 43 of the firstauxiliary flap 40 is moved downward a little from where it is in the first air direction but is moved upward a little from where it is in the fourth air direction, and the firstauxiliary flap 40 adopts a posture in which it pushes a little downward the airflow blown out from theair outlet 27. Furthermore, in the fifth air direction, the posture of the airdirection adjustment member 50 is the same as it is in the fourth air direction. Because the secondauxiliary flap 30, the firstauxiliary flap 40, and the airdirection adjustment member 50 adopt such postures, the air that has been blown out can be carried to a place farther away in front than in the fourth air direction. - The position of the
front end 33 of the secondauxiliary flap 30 shown inFIG. 6 ,FIG. 7 ,FIG. 8(a), and FIG. 8(b) is lower than therotational center 45 of the firstauxiliary flap 40. In contrast, the position of the secondauxiliary flap 30 when it is stowed in therecess 16g is higher than therotational center 45 of the firstauxiliary flap 40. The firstauxiliary flap 40 in the position shown inFIG. 6 to FIG. 8(b) on the path on which the secondauxiliary flap 30 rotates gets in the way as the secondauxiliary flap 30 rotates to the position of the secondauxiliary flap 30 shown inFIG. 6 to FIG. 8(b) . That is to say, if the firstauxiliary flap 40 were in the position shown inFIG. 6 to FIG. 8(b) when the secondauxiliary flap 30 is stowed in therecess 16g, the secondauxiliary flap 30 would end up hitting the firstauxiliary flap 40 and not be able to rotate to the position shown inFIG. 6 to FIG. 8(b) . Therefore, for example, in a state in which the firstauxiliary flap 40 has rotated forward so that it is closest to thecasing 11, or in other words in a state in which the firstauxiliary flap 40 is along thecasing 11, first the secondauxiliary flap 30 stowed in therecess 16g is moved rearward to the position shown inFIG. 6 to FIG. 8(b) . Next, the firstauxiliary flap 40 is rotated rearward to the position shown inFIG. 6 to FIG. 8(b) . In this way, by performing a rotational motion in which the secondauxiliary flap 30 and the firstauxiliary flap 40 avoid interfering with each other, thefront end 33 of the secondauxiliary flap 30 can switch between a state in which it is higher than therotational center 45 of the firstauxiliary flap 40 and a state in which it is lower than therotational center 45 of the firstauxiliary flap 40. -
FIG. 10(a) shows an end surface of the airdirection adjustment member 50 cut by line I-I ofFIG. 3 .FIG. 10(b) shows a side surface of the airdirection adjustment member 50 as seen from the right side.FIG. 11 shows a state in which the airdirection adjustment member 50 is broken out at its central part and seen from the right and above. The airdirection adjustment member 50 has a hollow structure where a plate-like member configuring the air direction adjustment memberupper surface 51 and a plate-like member configuring the air direction adjustment memberlower surface 52 are fused together. Because the airdirection adjustment member 50 has a hollow structure, this leads to deformation of the airdirection adjustment member 50 if a concentration of stress occurs in the air direction adjustment memberupper surface 51 and the air direction adjustment memberlower surface 52. If the airdirection adjustment member 50 deforms, a large gap forms between the airdirection adjustment member 50 and thecasing 11 when operation is stopped, for example, and the visual attractiveness is reduced. - In order to prevent such a concentration of stress, a supported
portion 53 is provided in arecess portion 60 in a central pivotally supported part of the airdirection adjustment member 50. As shown inFIG. 12 , the supportedportion 53 in the central pivotally supported part is rotatably supported by asupport portion 71 that bridges theupper edge 27a and thelower edge 27b of theair outlet 27 of thecasing 11. Furthermore,flanges 59 greater in width than the thickness of the airdirection adjustment member 50 are attached to aright end portion 61 and aleft end portion 62 of the air direction adjustment member 50 (seeFIG. 3 ). Additionally, supportedportions 53 are provided on theflanges 59. The supportedportions 53 on theflanges 59 are rotatably fitted into support portions (not shown in the drawings) provided in thecasing 11. - Next, before describing a recessed
portion 57 provided in the airdirection adjustment member 50, the relationship between the posture of the airdirection adjustment member 50 and the airflow will be described. As shown inFIG. 13(a) , at the time of the second air direction, for example, the air conditioningindoor unit 10 generates an airflow that flows along the installation side wall WL, and this airflow will be called a first airflow CL1. When generating the first airflow CL1, the airdirection adjustment member 50 adopts a posture in which the air direction adjustment memberupper surface 51 rotates rearward relative to a vertical plane so that thefront end 55 of the airdirection adjustment member 50 is positioned more rearward than therear end 56, and this posture will be called a first posture. - Furthermore, as shown in
FIG. 13(b) , at the time of the first air direction, the third air direction, or the fifth air direction, for example, the air conditioningindoor unit 10 generates an airflow that heads forward from theair outlet 27, and this airflow will be called a second airflow CL2. When generating the second airflow CL2, the airdirection adjustment member 50 adopts a posture in which the air direction adjustment memberupper surface 51 rotates forward relative to a vertical plane so that thefront end 55 of the airdirection adjustment member 50 is positioned more forward than therear end 56, and this posture will be called a second posture. -
FIG. 14 shows an enlarged view of the area around thelower edge 27b of theair outlet 27 in a state in which the airdirection adjustment member 50 is adopting the first posture. A recessedportion 57 is formed by a step in the air direction adjustment memberlower surface 52. In the cross-sectional shape in which the airdirection adjustment member 50 is cut by a plane perpendicular to the right and left direction, the front side of the air direction adjustment memberlower surface 52 describes a curved line that is convex downward, while the rear side describes a curved line that is convex upward. Because of this structure of the air direction adjustment memberlower surface 52, the rear side of the air direction adjustment memberlower surface 52 that describes a curved line that is convex upward is recessed upward to form a step, and this upwardly recessed step part is the recessedportion 57. - The air
direction adjustment member 50 is attached in such a way that, at the time of the second air direction in which the airdirection adjustment member 50 adopts the first posture, thelower edge 27b of theair outlet 27 enters the recessedportion 57 formed in the air direction adjustment memberlower surface 52. Consequently, compared to a case where there is no recessedportion 57 in the air direction adjustment memberlower surface 52, thefront end 55 of the airdirection adjustment member 50 can be moved further rearward by how much thelower edge 27b enters the recessedportion 57. As a result, compared to a case where there is no recessedportion 57, the airflow can be made to flow along the installation side wall WL from a higher position because there is the recessedportion 57. - As shown in
FIG. 14 , in thelower edge 27b, adepression portion 72 that is set rearward is formed andgroove portions 73 that are recessed rearward are formed. Compared to cases where thelower edge 27b is given a shape in which it is vertically cut out straight or where the shape of thelower edge 27b is formed in such a way that it projects forward heading downward, thefront end 55 of the airdirection adjustment member 50 can be moved further rearward because thedepression portion 72 is formed. In other words, this means that the airdirection adjustment member 50 can adopt a posture in which the air direction adjustment memberupper surface 51 is rotated rearward relative to a vertical plane. As a result, in the second air direction, the airdirection adjustment member 50 can adopt the first posture in which it allows the airflow to flow along the installation side wall WL from a higher position compared to a case where thedepression portion 72 is not formed. - When the air
direction adjustment member 50 has adopted the first posture, a gap forms between thelower edge 27b and the air direction adjustment memberlower surface 52. When cool air flows through this gap, depending on environmental conditions sometimes dew condensation forms on thelower edge 27b and the airdirection adjustment member 50. Thegroove portions 73 fulfill the role of disrupting the airflow that arises in this gap. The airflow that arises in the gap is disrupted and the air is agitated, whereby it becomes difficult for condensation to form. - In the embodiment, a case was described where the recessed
portion 57 is formed by a step in the air direction adjustment memberlower surface 52, but as with asloping end surface 57A of an airdirection adjustment member 50A shown inFIG. 15 andFIG. 16 , a recessed portion can also be formed by thesloping end surface 57A. In a cross-sectional shape in which the airdirection adjustment member 50A is cut by a plane perpendicular to the right and left direction, the front side of an air direction adjustment memberlower surface 52A describes a gentle curved line that is convex downward, while the rear side describes a straight line with a large inclination. Because of the structure of this air direction adjustment memberlower surface 52A, a recessed portion is formed by thesloping end surface 57A on the rear side of the air direction adjustment memberlower surface 52A. - A
sloping end surface 74 is also formed in thelower edge 27b of theair outlet 27, which opposes thesloping end surface 57A serving as a recessed portion when the airdirection adjustment member 50A adopts the first posture. It is preferred that thesloping end surface 57A serving as a recessed portion and thesloping end surface 74 of thelower edge 27b be configured to become parallel to each other when the airdirection adjustment member 50A has rotated rearward so that thefront end 55 has moved rearward its maximum extent. It will be noted that thegroove portions 73 described in the embodiment may also be formed in the sloping end surface of thelower edge 27b. - According to the wall-mounted air conditioning
indoor unit 10 of the present embodiment, thelower edge 27b of theair outlet 27 enters the recessed part of the recessedportion 57 or thesloping end surface 57A serving as a recessed portion of the airdirection adjustment member direction adjustment member lower surfaces FIG. 10 andFIG. 16 are the recessed part of the recessedportion 57 and thesloping end surface 57A serving as a recessed portion. Because thelower edge 27b enters the recessed part of the recessedportion 57 or thesloping end surface 57A serving as a recessed portion, the range of rotational motion can be increased, so restrictions on airflow control for ensuring comfort can be eased. Furthermore, in the air conditioningindoor unit 10, design attractiveness can be well maintained because the recessedportion 57 and thesloping end surface 57A serving as a recessed portion are formed in such a way that they are hardly noticeable in the air direction adjustment memberlower surfaces portion 57 or thesloping end surface 57A serving as a recessed portion, for example. - As shown in
FIG. 14 , in thecasing 11 of the air conditioningindoor unit 10, thedepression portion 72 corresponding to the shape of the air direction adjustment memberlower surface 52 is formed in thelower edge 27b of theair outlet 27 and in a position opposing the rear end portion of the air direction adjustment memberlower surface 52 of the airdirection adjustment member 50 that has adopted the first posture. Because thedepression portion 72 is provided in correspondence to the shape of the air direction adjustment memberlower surface 52, the range of rearward rotation of the airdirection adjustment member 50 can be increased compared to a case where thedepression portion 72 is not provided. As a result, restrictions on the airflow control of the air conditioningindoor unit 10 can be eased by how much the rotational range is increased. - As shown in
FIG. 14 , thegroove portions 73 provided in thelower edge 27b of theair outlet 27 of thecasing 11 are formed opposing the gap between the airdirection adjustment member 50 and thecasing 11. As a result, the air that flows through the gap between the airdirection adjustment member 50 and thecasing 11 can be agitated, and thegroove portions 73 can keep condensation from forming in the gap between the airdirection adjustment member 50A and thecasing 11. - As shown in
FIG. 15 andFIG. 16 , thesloping end surface 57A serving as a recessed portion of the airdirection adjustment member 50A and thesloping end surface 74 of thecasing 11 oppose each other when the airdirection adjustment member 50A adopts the first posture, so the range of rearward rotation of the airdirection adjustment member 50A can be increased. Restrictions on the airflow control of the air conditioningindoor unit 10 can be eased by how much the rotational range is increased by the sloping end surfaces of the airdirection adjustment member 50 and thecasing 11. - Compared to a case where the recessed
portion 57 is not provided in the airdirection adjustment member 50, the strength of the rear end portion of the airdirection adjustment member 50 drops because of the recessedportion 57 in the rear end portion of the airdirection adjustment member 50. By providing theflanges 59 on the side portions of the recessedportion 57, the airdirection adjustment member 50 is reinforced by theflanges 59 and deformation of the airdirection adjustment member 50 can be reduced even when the recessedportion 57 is provided in the rear end portion of the airdirection adjustment member 50. Because the airdirection adjustment member 50 is reinforced by theflanges 59, a drop in the air direction adjustment function caused by deformation of the airdirection adjustment member 50 can be prevented and design attractiveness can be prevented from being reduced by deformation of the airdirection adjustment member 50. -
