FIG. 1 is a front view of the wall-mounted indoor apparatus in a state in which operation has been stopped. A plan view and a side view of the wall-mounted indoor apparatus ofFIG. 1 are shown inFIGS. 2 and3 . In the description below, the wall-mountedindoor apparatus 1 is referred to as "indoor apparatus 1." In addition, when facing thefront surface 2F of amain body 2 of theindoor apparatus 1, the right hand side is left in theindoor apparatus 1, and the left hand side is right in theindoor apparatus 1. - The
indoor apparatus 1 shown inFIGS. 1 to 3 comprises a heat exchanger (not shown) and a fan (not shown) that are disposed inside themain body 2, which has afront surface 2F, left andright side surfaces 2S, aback surface 2B, anupper surface 2U, and abottom surface 2D. Themain body 2 has a rectangular shape that is elongated in the horizontal direction (transverse direction) as seen from the front surface and a rectangular shape that is elongated in the vertical direction as seen from the side surface. From a plan view, thefront surface 2F and theback surface 2B are parallel, and the middle of the side surface 2s has a horizontally elongated shape that is elongated in the horizontal direction. An attachment part (not shown) is provided on theback surface 2B of themain body 2. Theback surface 2B of themain body 2 faces the wall surface when theindoor apparatus 1 is attached to a wall surface. -
FIG. 4 is an elevated oblique view showing the contour of theindoor apparatus 1 when viewed from the front-left of theindoor apparatus 1. The internal protruding space will be described with reference toFIG. 4 . As shown inFIG. 4 , themain body 2 of theindoor apparatus 1 can be divided into three portions in the depthwise direction. Specifically, themain body 2 comprises aback surface part 2c in the vicinity of theback surface 2B that faces the wall surface to which the unit is attached, a depthwise-central part 2b that is to the front of theback surface part 2c, and afront surface part 2a that is to the front of the depthwise-central part 2b. Thefront surface part 2a and theback surface part 2c are extremely thin spaces that are in the vicinity of thefront surface 2F and theback surface 2B of themain body 2. For example, the depth of thefront surface part 2a is about 5 mm from thefront surface 2F and the depth of the back surface part 2C is about 5 mm from theback surface 2B. The depth of thefront surface part 2a and the depth of the back surface part 2C are substantially same as the thickness of thecasing 6. - A frontward space SP1 is present in the depthwise-
central part 2b to the front of theback surface part 2c. The frontward space SP1 has the same width and height as theback surface part 2c. The frontward space SP1 has end surfaces SF1 and SF2 to the left and right side. These end surfaces SF1 and SF2 are the rectangular surfaces that are bounded by the single-dotted line and the two dashed lines inFIG. 4 and are surfaces that face towards theside surface 2S of themain body 2. - The depthwise-
central part 2b comprises a frontward space SP1, an internal protruding space SP2 that extends farther to the left from the frontward space SP1, and an internal protruding space SP3 that extends out farther to the right from the frontward space SP1. The internal protruding space SP2 is a space that is between the left end surface SF1 of frontward space SP1 and theleft end surface 2S of the main body. InFIG. 4 , the upper surface and the lower surface of the internal protruding space SP2 are shaded with diagonal lines. An internal protruding space SP3 that has a shape that is symmetrical with the internal protruding space SP2 is between the right end surface SF2 and theright side surface 2S. Functional components are disposed in at least one of these internal protruding spaces SP2, SP3. The proximal spaces that are contiguous to the internal protruding spaces SP2, SP3 are described below. - As shown in
FIG. 1 , theindoor apparatus 1 has amovable panel 3 that covers all of thefront surface 2F of themain body 2 and a part of theside surface 2S. Thismovable panel 3 comprises afront surface part 3a which is flat andside surface parts 3b which curve smoothly. Thefront surface part 3a runs along thefront surface 2F and covers all thefront surface 2F. Theside surface parts 3b follow along the side surfaces 2S to the left and the right of themain body 2, covering parts of the side surfaces 2S. As shown inFIG. 2 , theside surface parts 3b of themovable panel 3 are curved in a circular arc as viewed from the upper surface. - As is clear from
FIG. 1 , the only part that can be seen from the front is themovable panel 3. When viewed from the front surface, primarily only the flatfront surface part 3a of themovable panel 3 is seen, giving the impression that the wall is embossed outward, reducing obtrusiveness to occupants of the room. In addition, because theside surface parts 3b of themovable panel 3 curve smoothly with an arc, there is no ridge present between thefront surface part 3a and theside surface part 3b, and theindoor apparatus 1 is thus made to be less obtrusive to occupants than parts in which a defined ridge is seen. - The
side surface part 3b, as is seen inFIGS. 2 and3 , extends to the widest lateral location of the depthwise-central part 2b. Acosmetic panel 4 is formed on theside surface 2S of themain body 2 farther to the rear from theside surface part 3b. In the portion in which themovable panel 3 and thecosmetic panel 4 meet, the surface position of theside surface part 3b of themovable panel 3 and the surface of thecosmetic panel 4 are made flush so that there is no step at the end parts of the surface of theside surface part 3b of themovable panel 3 and the surface of thecosmetic panel 4. For this reason, no seam between themovable panel 3 and thecosmetic panel 4 is seen when viewed from the front of theindoor apparatus 1. - With the
side surface 2S of themain body 2 that is constituted by thecosmetic panel 4 and theside surface part 3b of themovable panel 3, themain body 2 has a gradually narrowing width in a portion of thecosmetic panel 4. For this reason, thecosmetic panel 4 has aside surface 2S on the left of themain body 2 as seen from a plan view that curves smoothly in the shape of an S. Theside surface 2S on the right curves smoothly in the shape of a reverse S. - In this manner, the lateral width of the depthwise-
central part 2b is larger in comparison to that of theback surface part 2c, and thus an internal protruding space is formed inside the side surfaces 2S of a portion of the depthwise-central part 2b. - This
cosmetic panel 4 is attached to acover member 30 of the main body 2 (refer toFIG. 2 ). Thecover member 30 is attached to acasing 6 that covers themain body 2. Thecasing 6, as shown inFIG. 2 , has a lattice-form grille 6b in theupper surface 2U of themain body 2, and afirst intake opening 7 is formed in a portion of thegrille 6b. -
FIG. 5 is an oblique view of theindoor apparatus 1 as seen from below and to the left of theindoor apparatus 1. Themain body 2 has a bottom surface of thecasing 6 on thebottom surface 2D. Adischarge opening 9 is formed in the bottom surface of thecasing 6. Thisdischarge opening 9 is formed in thefront surface 2F as well as in thebottom surface 2D of themain body 2, as will be described below. Aflap 10 is provided on thedischarge opening 9 in order to adjust the blowing direction of conditioned air that is discharged from thedischarge opening 9 upwards or downwards. When operation is stopped, theflap 10 covers thedischarge opening 9 as shown inFIG. 5 . However, when theflap 10 closes off thedischarge opening 9, the respective surface positions align so that the surface of theflap 10 and the surface of the bottom surface of thecasing 6 reside on the same line so that they constitute a single surface. In addition, a circular comparativelylarge pushbutton switch 11 is provided following the shape of theside surface 2S on the left side on thebottom surface 2D of themain body 2. The power is turned on and off using thispushbutton switch 11. Thepushbutton switch 11 not only turns the power on and off, but is formed from material that transmits infrared light, so that infrared light that has passed through thepushbutton switch 11 can be received inside themain body 2. In addition, thering 11a surrounding thepushbutton switch 11 is formed from a material that is transmissive with respect to light, and can thus externally transmit light from light-emitting diodes that are provided inside themain body 2. The disposition of infrared receiving parts and light-emitting diodes is described below. - The
movable panel 3 rises to its highest point during operation and drops to its lowest point when not in operation. Consequently, there are two locations where themovable panel 3 of theindoor apparatus 1 rests: at the highest point and at the lowest point.FIGS. 6 to 10 show a state in which theindoor apparatus 1 is operating and themovable panel 3 has been lifted upwards.FIG. 6 is a front view of theindoor apparatus 1.FIG. 7 is a side view thereof.FIG. 8 is a plan view of theindoor apparatus 1.FIG. 9 is an elevated view of theindoor apparatus 1 from the front left of theindoor apparatus 1, andFIG. 10 is an elevated oblique view of theindoor apparatus 1 from the back-left of theindoor apparatus 1. - As shown in
FIG. 6 , the moving of themovable panel 3 to its highest point causes thefirst opening part 9a formed below thecasing 6 to assume a state of being visible from the front. Thedischarge opening 9 that was described previously and is shown inFIG. 5 comprises afirst opening part 9a and asecond opening part 9b that is formed on the bottom surface of thecasing 6 but can be covered by theflap 10. Thefirst opening part 9a and thesecond opening part 9b are connected and meet with the outlet of the discharge flow path (not shown) that is provided in themain body 2 and faces downwards at an angle. InFIG. 6 , thesecond opening part 9b is closed off by theflap 10, but, inFIG. 9 , theflap 10 rotates and opens thesecond opening part 9b because the flap is situated in the discharge flowpath. During operation, thebottom end part 3c of themovable panel 3 rises above the position of the upper edge of thefirst opening part 9a so that at least thefirst opening part 9a is opened. - In addition, with the
lower end part 3c of themovable panel 3 positioned above the upper edge of thefirst opening part 9a, theperson detection sensor 12 that is provided on thefront surface 6a of thecasing 6 will become exposed and assume a state of being capable of detecting people. - When the
movable panel 3 moves upwards, the distance over which thelower end part 3c moves to the front and back is small, and the frontward movement of theupper end part 3d is large. For this reason, as shown inFIG. 7 , when viewed from the side, theupper end part 3d moves forwards more than thelower end part 3c, and themovable panel 3 inclines to the front. As a result, anopening part 13 is formed between theback surface 3e of themovable panel 3 and thefront surface 6a of thecasing 6. InFIG. 6 orFIG. 9 , a second intake opening is provided on thefront surface 6a of thecasing 6, although it is shielded by themovable panel 3 and cannot be seen. By forming theopening part 13, it is possible to take in indoor air from the second intake opening that is provided on thefront surface 6a of thecasing 6. The second intake opening is shown below inFIG. 16 . - In this manner, indoor air is taken in downward from the opening
part 13 that has an upper end that broadens like a funnel, so that the flow of indoor air that is taken in from the second intake opening and flow of conditioned air that is discharged from thedischarge opening 9 are generated on both sides of themovable panel 3 in the vicinity of thelower end part 3c of themovable panel 3. For this reason, if the gap between thelower end part 3c of themovable panel 3 and thefront surface 6a of thecasing 6 is large, then conditioned air will enter into the flow of the indoor air, and conversely, indoor air flowing through the back surface side of themovable panel 3 will enter into the flow of conditioned air, which will cause undesirable effects such as the production of condensation. Thus, when themovable panel 3 reaches its highest point, an operation is carried out whereby thelower end part 3c of themovable panel 3 is drawn towards thefront surface 6a of thecasing 6. - In addition, for similar reasons, due to the deformation of the
movable panel 3, it is undesirable for a gap to arise between thebottom end part 3 c of themovable panel 3 and thefront surface 6a of thecasing 6. A material that is light and has comparatively high stiffness such as plastic or plastic-clad aluminum is used for themovable panel 3. However, the stiffness of the plate-form member that constitutes themovable panel 3 alone is insufficient to prevent a gap of this type from being formed. Thus, with the objective of further increasing stiffness, ahollow metal bar 14 or the like that is made of stainless steel is affixed to the back side of thefront surface part 3a of themovable panel 3 as shown inFig 8 or10 . - The
movable panel 3 is supported by apanel support arm 15 on which a rack gear is formed as shown inFIG. 8 orFIG. 10 . Thepanel support arm 15 moves as a result of drive force being transmitted from a stepper motor described below to the rack gear. - As described previously, in order to provide the
indoor apparatus 1 with superior external appearance, themovable panel 3 constituted so as to cover a part of theside surface 2S of themain body 2 as well as the entirefront surface 2F of themain body 2, and the movable panel thus becomes heavy. In addition, in order to take in indoor air from the second intake opening, the allowed amount of deformation is small, and a material with high stiffness is thus required. The weight of themovable panel 3 thus tends to increase further. In addition, because themovable panel 3 does not simply slide upwards and downwards, and a more complex operation is required, the load on the support member of themovable panel 3 such as thepanel support arm 15 is increased. - A side view of the
indoor apparatus 1 with themovable panel 3 removed is shown inFIG. 11 . In the state shown inFIG. 11 , themovable panel 3 has been removed from thepanel support arm 15 in the state shown inFIG. 7 with themovable panel 3 rested at its highest point. -
FIGS. 12 ,13 , and14 illustrate the structure and operation of thepanel support arm 15 with a portion of the apparatus that includes thepanel support arm 15 and the peripheral parts.FIG. 12 shows a state in which themovable panel 3 is at its lowest point with operation stopped (closed condition).FIG. 14 shows a state in which themovable panel 3 is at its highest point with operation being carried out (open condition).FIG. 13 shows a state occurring during movement from the state shown inFIG. 12 to the state shown inFIG. 14 , or, conversely, a state occurring during movement from the state ofFIG. 14 to the state ofFIG. 12 . - The
movable panel 3 shown inFIGS. 12 to 14 has a clad structure formed from analuminum plate 3m and aplastic plate 3n. Afirst linking part 16a and asecond linking part 16b are provided on the back surface side of theplastic plate 3n in order to link to thepanel support arm 15. Thefirst linking part 16a that is provided in the vicinity of theupper end part 3d of themovable panel 3 links with theopening part 15a that is provided on the upper part of thepanel support arm 15. On the other hand, thesecond linking part 16b is provided at a height of approximately one-fourth the height of themovable panel 3 referenced from thelower end part 3c of themovable panel 3. Thissecond linking part 16b links with the linkingpart 15b that is provided on the lower part of thepanel support arm 15. Themovable panel 3 and thepanel support arm 15 are constituted so that they can be attached and removed by carrying out the linking referred to above. - The
panel support arm 15 is constituted by a plate-form member that resembles a triangular square with the width decreasing towards the upper part. A first slidingopening 15d and a second slidingopening 15e are formed in the shape of long holes that are formed with the same angle with respect to theedge 15c with which themovable panel 3 is in close contact. In addition, aroller 15f is attached at the apex of thepanel support arm 15 farthest from theedge 15c. - The
panel support arm 15 is housed inside athin case 17 constituted by the mating of two plate-form member sheets. A cylindricalfirst support member 20a that fits inside the first slidingopening 15d so that it can slide through the first slidingopening 15d and a cylindricalsecond support member 20b that fits inside the second slidingopening 15e so that it can slide through the second slidingopening 15e are fixed with screws to one of the plate-form members 18 that constitute thethin case 17. Aguide part 18a that can move while striking theroller 15f is formed at the periphery of the plate-form member 18. - This
guide part 18a comprises a guide wall 18a1 that extends linearly and a recess part 18a2 that leads to the upper part of the guide wall 18a1. The recess part 18a2 is at a position that is farther from theedge 15c with respect to a straight line extended along the guide wall 18a1. In addition, the second slidingopening 15e comprises a long upper opening 15e1 and a very short lower opening 15e2. The distance between the upside of the upper opening 15e1 and theedge 15c is shorter than the distance between the downside of the upper opening 15e1 and theedge 15c. The distance between the upside of the lower opening 15e2 and theedge 15c is longer than the distance between the downside of the lower opening 15e2 and theedge 15c. - The
guide part 18a has a depression part 18a2, and the second slidingopening 15e has a lower opening 15e2, and thus themovable panel 3 has a complicated movement. When thesecond support member 20b slides from above to below through the upper opening 15e1 of the second slidingopening 15e, as themovable panel 3 moves upwards, theupper end part 3d of themovable panel 3 assumes a large separation from thefront surface 6a of thecasing 6, whereas thelower part 3c separates slightly from thefront surface 6a. When thesecond support member 20b then enters into the lower opening 15e2, theroller 15f enters into the recess part 18a2. At this time, thepanel support arm 15 moves while rolling with thefirst support member 20a as the center, and theupper end part 3d of themovable panel 3 moves so that it is even farther from thefront surface 6a of thecasing 6, whereas thelower end part 3c moves so that it approaches thefront surface 6a. The trajectory of the movement of themovable panel 3 is shown inFIG. 15 . - The
panel support arm 15 carries out an operation involving movement through the transmission of drive force from the drivengear 21 to the rack gear of thepanel support arm 15 shown inFIGS. 12 to 14 . Power is transmitted to the drivengear 21 from adrive gear 22 that is linked to the drive shaft of a stepper motor described below. The drivengear 21 and thedrive gear 22 are attached on the inside of thethin case 17, and the drivengear 21 meshes with the rack gear of thepanel support arm 15. - The operation whereby the heavy
movable panel 3 described above and thepanel support arm 15 having a complicated movement are installed so as to allow proper functioning becomes difficult when other members are densely packed at the periphery. For this reason, the members such as thepanel support arm 15 in theindoor apparatus 1 are provided in the internal protruding space of the depthwise-central part 2b of themain body 2. - The installation site, for the
panel support arm 15 and peripheral members thereof, described above with reference toFIGS. 12 to 14 , will now be described. A state in which themovable panel 3 of theindoor apparatus 1 has been removed is shown inFIGS. 16 and17 .FIG. 16 is a front view of theindoor apparatus 1, andFIG. 17 is a plan view of theindoor apparatus 1. - As shown in
FIG. 16 , thesecond intake opening 27 is provided on thefront surface 6a of thecasing 6. Thesecond intake opening 27, as with thefirst intake opening 7, is slightly closer to the right of themain body 2. From this, it will be understood that the force that is received by themovable panel 3 from the indoor air that is taken into thesecond intake opening 27 is slightly larger towards the right of themain body 2. Although the force that is placed on themovable panel 3 is different on the right and left, there must be no shift in the positions, at which support by thepanel support arms 15, provided on the left and right, occurs. For this reason as well, installation of thepanel support arm 15 becomes important. - The
panel support arm 15 is disposed in a position that is corresponding to the protrudingregions FIG. 16 . From a front view, the positions of the protrudingregions side surface part 3b of themovable panel 3. Thecover member 30 is installed on the protrudingregions main body 2 describes a shape that protrudes in the horizontal direction farther than thecasing 6 by exactly the amount of thecover member 30. Thiscover member 30 is fixed to thecasing 6 by ascrew 31. In addition, thepanel support arm 15 and peripheral members described inFIGS. 12 to 14 are fixed to thecasing 6 byscrews 32. -
FIG. 18 is a view ofFIG. 16 across a section A-A.FIGS. 20 and21 show a state in which thescrew 31 has been detached and thecover member 30 has been removed.FIG. 20 is an elevated oblique view of theindoor apparatus 1 from the front and left, andFIG. 21 is a left side view of theindoor apparatus 1. - As shown in
FIG. 18 , a large innerprotruding space 33 is formed in the portion corresponding to the depthwise-central part 2b in between thecover member 30 and thecasing 6. Because this inner protrudingspace 33 is present, thestepper motor 25 can be disposed outside thethin case 17 in the lateral direction. Thiscase 17 is constituted by the mating of a plate-form member 18 and a transparent plate-form member 19. Thestepper motor 25 inserts into the transparent plate-form member 19. As is clear fromFIG. 18 , thecover member 30 has the shape of a longitudinally half of a cylinder with a downward bulge, similar to the shape of a longitudinally half of a pear, and there is no comparative excess of space formed inside themain body 2. For example, given the shape indicated by the double-dotted line, an excesslarge space 34 is formed in the area close to theback surface 2B of themain body 2. By cutting off such excess space, and allowing the shape of the protrudingcover member 30 to be smoothly curved, the shape of theside surface 2S of themain body 2 can be finished off to produce an external appearance that is minimally intrusive to the occupant. - As shown in
FIG. 20 , when thecover member 30 is removed, the structure of the surroundings of thepanel support arm 15 and thestepper motor 25 is exposed three-dimensionally. As a result, the operations whereby the peripheral structures of thepanel support arm 15 and thestepper motor 25 are installed on the side surface of thecasing 6 are facilitated. In other words, a plate-form member 18 can be screwed to thecasing 6 together with thethin case 17 in which thestepper motor 25 is installed, and installation of the flatthin case 17 in a flat location such as theside wall 6c of thecasing 6 is readily achieved. - After assembly has been completed in this manner, when the
cover member 30 is removed, the entire surroundings of thestepper motor 25 and thepanel support arm 15 can be exposed three-dimensionally. For this reason, there is little limitation on the directions from which tools can be inserted, and maintenance operations are facilitated. - Moreover, because the transparent plate-
form member 19 covers the outer side surface of thepanel support arm 15, movement of the driving components such as thepanel support arm 15, the drivengear 21, thedrive gear 22, and thestepper motor 25 can be checked by looking through the transparent plate-form member 19. - In order to detect the position of the
panel support arm 15, alimit switch 26 is provided on thecase 17. A plate-form sheet 28 having a step is installed on the panel support arm 15 (refer toFIG. 21 ), and the plate-form sheet 28 moves together with thepanel support arm 15. The step of this plate-form sheet 28 is detected by thelimit switch 26 and position detection is thus carried out by thelimit switch 26. - As described above, because the
roller 15f enters into the recess part 18a2 in the support structure of themovable panel 3, support of themovable panel 3 is bolstered. Once theroller 15f enters into the recess part 18a2, in order for theroller 15f to leave the recess part 18a2, the roller must overcome the difference in level between the recess part 18a2 and the guide wall 18a1, and support thus can be bolstered. Consequently, with thelimit switch 26, it is necessary to detect that thepanel support arm 15 has definitely moved to a position at which theroller 15f enters into the recess part 18a2 (that it has reached the highest point). Because of this, it is necessary to accurately provide thelimit switch 26 or the plate-form sheet 28 at the correct position and in the correct orientation. By using the internalprotruding space 33, thelimit switch 26 and plate-form sheet 28 can be placed together with thecase 17 housing thepanel support arm 15, and attachment is thus carried out easily and accurately. In addition, during maintenance, the peripheral members of thecase 17 are exposed three-dimensionally, and so adjustment using tools or the hands as well as replacement of parts can be easily carried out. - Across the internal
protruding space 33 and the spaces contiguous therewith, in addition to thestepper motor 25, a printed wiring board 40 (functional component) on which electrical parts are mounted is disposed as shown inFIG. 21 . The printedwiring board 40 is disposed above thepushbutton switch 11. A light-receiving element 41 that receives infrared light is carried on this printedwiring board 40, and the controller thereof is formed. The light-receiving element 41 is disposed directly above the middle point of thepushbutton switch 11. The reason that maintenance and installation of the printedwiring board 40 are facilitated is the same as the reason that maintenance and installation of functional components such as thepanel support arm 15 and thestepper motor 25 are facilitated. - In addition, a light-emitting
diode 42 that emits different colored light is disposed above aring 11a surrounding thepushbutton switch 11. The light-emittingdiode 42 is also carried on the printedwiring board 40. In order to relay different operations such as heating and cooling in accordance with the emitted light color, a configuration is provided whereby thering 11a surrounding thepushbutton switch 11 can be lighted in various colors. Maintenance of functional components involves maintenance of this type of light-emittingdiode 42 or light-receiving element 41. - The proximal spaces will now be described using
FIG. 19. FIG. 19 is a sectional view showing a state in which thepanel support arm 15, peripheral members thereof, thestepper motor 25, and the like have been removed fromFIG. 18 . The single dotted line in the drawing extends frontward with the left edge of theback surface part 2c as a base point. With theindoor apparatus 1, part of the back surface side of thecover member 30 constitutes theback surface part 2c. Thecover member 30 constitutes theside surface 2S of themain body 2, and a space is formed between thecover member 30 and theside wall 6c of thecasing 6. In essence, the space that is formed between theside wall 6c and thecover member 30 is a space that bulges out, but in order to clarify the range of terminology, the space outside of the single dotted line in the drawing is defined as the internalprotruding space 33. However, in cases where a functional component is disposed in aproximal space 33a that is contiguously connected with the inner protrudingspace 33 and is contiguous therewith, a similar function can be expected as when disposed in the inner protrudingspace 33. For example, although the space that is on the inside of thecasing 6 but past theside wall 6c is contiguous with the inner protrudingspace 33, similar function as the inner protrudingspace 33 clearly cannot be expected, and the space is not aproximal space 33a. In addition, the same functioning cannot be expected if the distance is too great, even if the space is connected. Consequently, the thickness of theproximal space 33a (distance from the inner protrudingspace 33 to the farthest location), in consideration of the size of the functional components that are used in a commonindoor apparatus 1, is preferably about 2 to 4 cm, more preferably less than 2 cm. -
FIGS. 22 and23 show six views and one sectional view of the left-side cover member 30 that constitutes the left side surface of theindoor apparatus 1. Specifically,FIG. 22(a) is a front view of thecover member 30,FIG. 22(b) is a left-side view,FIG. 22(c) is a back view, andFIG. 22(d) is a left-side view. In addition,FIG. 23(a) is a plan view,FIG. 23(b) is a bottom view, andFIG. 23(c) is a B-B sectional view. - As described previously, the
cover member 30 has a three-dimensional shape and thecover member 30, by virtue of being disposed on theside surface 2S of themain body 2, forms the inner protrudingspace 33. Because the external form of themain body 2 of theindoor apparatus 1 is made as small as possible, excess space is preferably not provided inside themain body 2, and so the shape of thecover member 30 describes a curve that has a smooth outward protrusion in the vicinity of thestepper motor 25 so as to tightly encompass thestepper motor 25. The shape of thecover member 30 as seen from a plan view will be described with reference toFIG. 23(a) . First, moving from the leading end towards theback surface 2B to the trailing end towards thefront surface 2F, the side surfaces gradually bulge in the width-wise direction of themain body 2. Next, a substantially semicircular arc is shown as starting from a location that is more than about 1/3 of the way and extending up to thefront surface 2F. The trailing end of thefront surface 2F and the leading end of theback surface 2B are at substantially the same positions in the widthwise direction (horizontal direction) of themain body 2. For this reason, sufficient innerprotruding space 33 is formed inside of the substantially semicircular arc to contain the functional components. When viewed in additional detail, a step is formed at the farthest protruding location of thecover member 30. This step is formed in order to constitute a single surface between themovable panel 3 and the outer surface of thecosmetic panel 4. - From a comparison of
FIG. 23(a), FIG. 23(b), and FIG. 23(c) , thecover member 30 can be seen to have a linear outline in the vertical direction of themain body 2. This is an aspect that is heavily dependent on design. For example, if there is excessive inner protrudingspace 33 in the upper part of themain body 2 then a configuration may be adopted in which the shape of the top surface inFIG. 23(a) is decreased more than the shape of the bottom surface inFIG. 23(b) . With a gentle curve, the functional components such as thestepper motor 25 that are provided in the inner protrudingspace 33 are contained within a side surface outer profile such as that of thecover member 30 while eliminating unnecessary internal space, thereby decreasing the intrusiveness of the device from the standpoint of the occupant. At the same time, assembly of the functional component disposed in the inner protrudingspace 33 is facilitated. - A latching
hook 35 is provided on the back surface side of thecover member 30. This latchinghook 35 inserts into a prescribed hole in thecasing 6. Inserting ascrew 31 into thehole 36, and screwing it into the screw hole of thecasing 6 enables thecover member 30 to be readily installed on thecasing 6. Arib 37 for reinforcing thecover member 30 is formed on the back surface of thecover member 30. -
- (1) In the embodiment described above, the
side surface 2S of themain body 2 was constituted by acover member 30 that can be removed. However, theside surface 2S of themain body 2 need not be removable and, for example, a configuration may be used in which theside surface 2S of themain body 2 is constituted by thecasing 6. In this case, ease of maintenance decreases, but is still higher than in the past, and installation operations are also easier than in the past. In the past, when the casing was removed, the parts that were densely packed on the side surfaces were spread out over a flat surface, whereas if a bulging side surface shape is adopted as with the embodiment described above, the densely packed parts are spread out in association with the shape of the bulging side surface. Consequently, by providing the side surface with a bulging curve as in the embodiment described above, the densely packed parts extend three-dimensionally along the shape of the side surface, and so insertion of a tool or hand is facilitated in this portion. As a result, installation operational efficiency and maintenance operational efficiency are improved. - (2) In the embodiment described above, the inner protruding
space 33 was formed over the entire height from thelower surface 2D to theupper surface 2U of themain body 2 in the vertical direction. However, even if the inner protrudingspace 33 is not formed across the entire height, there are cases where similar effects can be realized. For example, if thepanel support arm 15 is miniaturized to create extra space, then theside wall 6c of thecasing 6 can be made to protrude out and approach thecover member 30. Alternatively, by eliminating the bulge in the portion where excess space was generated and forming the inner protrudingspace 33 midway along the vertical direction, a design can be adopted in which the width of themain body 2 is narrowed only in the locations where the inner protrudingspace 33 is not provided. - (3) In the embodiment described above, the entire height of the
side surface 2S of themain body 2 was constituted by a single sheet of thecover member 30. However, thiscover member 30 may be divided midway and can be configured so that only part of theside surface 2S can be removed. For example, the cover member may fit only onto the upper half, with the lower half being constituted by the casing. -
- (a) The wall-mounted
indoor apparatus 1 has astepper motor 25 that is disposed in the inner protrudingspace 33 of themain body 2. In the past, the parts have been packed into the casing with the objective of minimizing the form of the indoor apparatus, and thus these types of conventional substantially cuboid main bodies have had flat side walls. Dense packing of other parts into the surroundings of thestepper motor 25 also has been common. In contrast, because the periphery of thestepper motor 25 is covered by acurved cover member 30 in the embodiments described above, the internal protruding space does not have room for any other parts, and almost all of thestepper motor 25 is exposed. As a result, installation operations for thestepper motor 25 are facilitated. On the other hand, because the shape of theside surface 2S of themain body 2 is a protruding shape that is smoothly curved, obtrusiveness can be decreased relative to cases where the transverse width of themain body 2 is increased.
Thestepper motor 25 is the arm driving motor for driving thepanel support arm 15. The arm driving motor of thepanel support arm 15 that must be supported without shifting of the position of themovable panel 3 must be disposed at a precise position, and so significant improvements can be anticipated by facilitating the installation operation for the arm driving motor. The arm driving motor is a type of moving part. The moving parts of theindoor apparatus 1 must be suited to a quiet space with few moving objects, such as in a living room. These types of moving parts have the function of being movable, and installation work typically is difficult in comparison to static parts. This tendency is particularly pronounced in cases where a large drive force must be transmitted or generated by the moving part. Significant operational efficiency improvement effects are obtained as a result of facilitating installation of moving parts of this type. In addition, moving parts are a type of functional component. Functional components have various functions, and must be installed in order to manifest these functions. Operational efficiency thus is significantly improved by facilitating installation of these types of functional components.
In particular, thecurved cover member 30 that encompasses the surroundings of thestepper motor 25 can be removed. Because thecover member 30 can be removed, when performing maintenance on thestepper motor 25, it is not necessary to remove thecasing 6, as in the past, which facilitates performing maintenance. In addition, even during installation operations for functional components such as thestepper motor 25, the operations can be carried out with thecasing 6 on. For example, if a plurality of fins are provided on the heat exchanger, carrying out operations without thecasing 6 covering the fins can lead to injury to the worker. However installation work can thus be facilitated while preventing such undesirable outcomes. - (b) The
panel support arm 15 supports themovable panel 3 that covers part of the side surfaces 2S of themain body 2 while also covering the entirefront surface 2F of themain body 2. In the embodiment described above, thepanel support arm 15 was disposed in theproximal space 33a. For this reason, thepanel support arm 15 can be installed together with thestepper motor 25 which is a functional component that is disposed in the inner protrudingspace 33. As a result, thepanel support arm 15 and thestepper motor 25 can be installed easily in precise positions, which simplifies the installation operation and improves operational efficiency. In the embodiment described above, thepanel support arm 15 was disposed in aproximal space 33a, but improvement in operational efficiency can likewise be obtained when disposed in the inner protrudingspace 33 or when disposed in the inner protrudingspace 33 and theproximal space 33a.
Thispanel support arm 15 is covered by the transparent plate-form member 19, and the working state of thepanel support arm 15 inside thecase 17 can be observed through the plate-form member 19. For this reason, it is easy to check the working state of thepanel support arm 15 during maintenance while also facilitating installation of thepanel support arm 15. Moreover, operation of the drivengear 21 or thedrive gear 22 can be checked, and operation of thestepper motor 25 also can be checked indirectly by checking operation of the gears through the transparent plate-form member 19. - (c) The light-receiving element 41 (light-receiving part) is disposed in the inner protruding
space 33. Thus, infrared light is received through thepushbutton switch 11. Because the light-receiving element 41 is separated from the outside of themain body 2, it is not readily influenced by changes in the indoor environment. Because the printedwiring board 40 having the light-receiving element 41 and controllers is disposed in the internal protruding space, the installation and removal operations of the light-receiving element 41 and the printedwiring board 40 on which is the controller thereof can be easily carried out. -
