From this, it will be understood that the force that is received by the movable panel 3 from the indoor air that is taken into the second intake opening 27 is slightly larger towards the right of the main body 2.
- the force that is placed on the movable panel 3 is different on the right and left, there must be no shift in the positions, at which support by the panel support arms 15, provided on the left and right, occurs. For this reason as well, installation of the panel support arm 15 becomes important.
- the panel support arm 15 is disposed in a position that is corresponding to the protruding regions 2d, 2e shown in FIG. 16 . From a front view, the positions of the protruding regions 2d, 2e overlap the position of the side surface part 3b of the movable panel 3.
- the cover member 30 is installed on the protruding regions 2d, 2e, and the main body 2 describes a shape that protrudes in the horizontal direction farther than the casing 6 by exactly the amount of the cover member 30.
- This cover member 30 is fixed to the casing 6 by a screw 31.
- the panel support arm 15 and peripheral members described in FIGS. 12 to 14 are fixed to the casing 6 by screws 32.
- FIG. 18 is a view of FIG. 16 across a section A-A.
- FIGS. 20 and 21 show a state in which the screw 31 has been detached and the cover member 30 has been removed.
- FIG. 20 is an elevated oblique view of the indoor apparatus 1 from the front and left
- FIG. 21 is a left side view of the indoor apparatus 1.
- a large inner protruding space 33 is formed in the portion corresponding to the depthwise-central part 2b in between the cover member 30 and the casing 6. Because this inner protruding space 33 is present, the stepper motor 25 can be disposed outside the thin case 17 in the lateral direction.
- This case 17 is constituted by the mating of a plate-form member 18 and a transparent plate-form member 19.
- the stepper motor 25 inserts into the transparent plate-form member 19.
- the cover 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 the main body 2.
- an excess large space 34 is formed in the area close to the back surface 2B of the main body 2.
- the shape of the side surface 2S of the main body 2 can be finished off to produce an external appearance that is minimally intrusive to the occupant.
- the transparent plate-form member 19 covers the outer side surface of the panel support arm 15, movement of the driving components such as the panel support arm 15, the driven gear 21, the drive gear 22, and the stepper motor 25 can be checked by looking through the transparent plate-form member 19.
- a limit switch 26 is provided on the case 17.
- a plate-form sheet 28 having a step is installed on the panel support arm 15 (refer to FIG. 21 ), and the plate-form sheet 28 moves together with the panel support arm 15. The step of this plate-form sheet 28 is detected by the limit switch 26 and position detection is thus carried out by the limit switch 26.
- roller 15f enters into the recess part 18a2 in the support structure of the movable panel 3, support of the movable panel 3 is bolstered.
- the roller 15f Once the roller 15f enters into the recess part 18a2, in order for the roller 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 the limit switch 26, it is necessary to detect that the panel support arm 15 has definitely moved to a position at which the roller 15f enters into the recess part 18a2 (that it has reached the highest point).
- the limit switch 26 or the plate-form sheet 28 can be placed together with the case 17 housing the panel support arm 15, and attachment is thus carried out easily and accurately.
- the peripheral members of the case 17 are exposed three-dimensionally, and so adjustment using tools or the hands as well as replacement of parts can be easily carried out.
- a printed wiring board 40 (functional component) on which electrical parts are mounted is disposed as shown in FIG. 21 .
- the printed wiring board 40 is disposed above the pushbutton switch 11.
- a light-receiving element 41 that receives infrared light is carried on this printed wiring board 40, and the controller thereof is formed.
- the light-receiving element 41 is disposed directly above the middle point of the pushbutton switch 11. The reason that maintenance and installation of the printed wiring board 40 are facilitated is the same as the reason that maintenance and installation of functional components such as the panel support arm 15 and the stepper motor 25 are facilitated.
- a light-emitting diode 42 that emits different colored light is disposed above a ring 11 a surrounding the pushbutton switch 11.
- the light-emitting diode 42 is also carried on the printed wiring board 40.
- a configuration is provided whereby the ring 11a surrounding the pushbutton switch 11 can be lighted in various colors. Maintenance of functional components involves maintenance of this type of light-emitting diode 42 or light-receiving element 41.
- FIG. 19 is a sectional view showing a state in which the panel support arm 15, peripheral members thereof, the stepper motor 25, and the like have been removed from FIG. 18 .
- the single dotted line in the drawing extends frontward with the left edge of the back surface part 2c as a base point.
- part of the back surface side of the cover member 30 constitutes the back surface part 2c.
- the cover member 30 constitutes the side surface 2S of the main body 2, and a space is formed between the cover member 30 and the side wall 6c of the casing 6.
- the space that is formed between the side wall 6c and the cover 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 internal protruding space 33.
- a functional component is disposed in a proximal space 33a that is contiguously connected with the inner protruding space 33 and is contiguous therewith, a similar function can be expected as when disposed in the inner protruding space 33.
- the thickness of the proximal space 33a is preferably about 2 to 4 cm, more preferably less than 2 cm.
- FIGS. 22 and 23 show six views and one sectional view of the left-side cover member 30 that constitutes the left side surface of the indoor apparatus 1.
- FIG. 22(a) is a front view of the cover member 30,
- FIG. 22(b) is a left-side view,
- FIG. 22(c) is a back view, and
- FIG. 22(d) is a left-side view.
- FIG. 23(a) is a plan view
- FIG. 23(b) is a bottom view
- FIG. 23(c) is a B-B sectional view.
- the cover member 30 has a three-dimensional shape and the cover member 30, by virtue of being disposed on the side surface 2S of the main body 2, forms the inner protruding space 33. Because the external form of the main body 2 of the indoor apparatus 1 is made as small as possible, excess space is preferably not provided inside the main body 2, and so the shape of the cover member 30 describes a curve that has a smooth outward protrusion in the vicinity of the stepper motor 25 so as to tightly encompass the stepper motor 25. The shape of the cover member 30 as seen from a plan view will be described with reference to FIG. 23(a) .
- 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 the front surface 2F.
- the trailing end of the front surface 2F and the leading end of the back surface 2B are at substantially the same positions in the widthwise direction (horizontal direction) of the main body 2. For this reason, sufficient inner protruding space 33 is formed inside of the substantially semicircular arc to contain the functional components.
- a step is formed at the farthest protruding location of the cover member 30. This step is formed in order to constitute a single surface between the movable panel 3 and the outer surface of the cosmetic panel 4.
- the cover member 30 can be seen to have a linear outline in the vertical direction of the main body 2. This is an aspect that is heavily dependent on design. For example, if there is excessive inner protruding space 33 in the upper part of the main body 2 then a configuration may be adopted in which the shape of the top surface in FIG. 23(a) is decreased more than the shape of the bottom surface in FIG. 23(b) .
- the functional components such as the stepper motor 25 that are provided in the inner protruding space 33 are contained within a side surface outer profile such as that of the cover 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 protruding space 33 is facilitated.
- a latching hook 35 is provided on the back surface side of the cover member 30. This latching hook 35 inserts into a prescribed hole in the casing 6. Inserting a screw 31 into the hole 36, and screwing it into the screw hole of the casing 6 enables the cover member 30 to be readily installed on the casing 6. A rib 37 for reinforcing the cover member 30 is formed on the back surface of the cover member 30.
- the stepper motor 25 is the arm driving motor for driving the panel support arm 15.
- the arm driving motor of the panel support arm 15 that must be supported without shifting of the position of the movable 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 the indoor 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.
- 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.
- the curved cover member 30 that encompasses the surroundings of the stepper motor 25 can be removed. Because the cover member 30 can be removed, when performing maintenance on the stepper motor 25, it is not necessary to remove the casing 6, as in the past, which facilitates performing maintenance. In addition, even during installation operations for functional components such as the stepper motor 25, the operations can be carried out with the casing 6 on. For example, if a plurality of fins are provided on the heat exchanger, carrying out operations without the casing 6 covering the fins can lead to injury to the worker. However installation work can thus be facilitated while preventing such undesirable outcomes.
- the panel support arm 15 supports the movable panel 3 that covers part of the side surfaces 2S of the main body 2 while also covering the entire front surface 2F of the main body 2.
- the panel support arm 15 was disposed in the proximal space 33a.
- the panel support arm 15 can be installed together with the stepper motor 25 which is a functional component that is disposed in the inner protruding space 33.
- the panel support arm 15 and the stepper motor 25 can be installed easily in precise positions, which simplifies the installation operation and improves operational efficiency.
- the panel support arm 15 was disposed in a proximal space 33a, but improvement in operational efficiency can likewise be obtained when disposed in the inner protruding space 33 or when disposed in the inner protruding space 33 and the proximal space 33a.
- This panel support arm 15 is covered by the transparent plate-form member 19, and the working state of the panel support arm 15 inside the case 17 can be observed through the plate-form member 19. For this reason, it is easy to check the working state of the panel support arm 15 during maintenance while also facilitating installation of the panel support arm 15. Moreover, operation of the driven gear 21 or the drive gear 22 can be checked, and operation of the stepper motor 25 also can be checked indirectly by checking operation of the gears through the transparent plate-form member 19.
- the light-receiving element 41 (light-receiving part) is disposed in the inner protruding space 33. Thus, infrared light is received through the pushbutton switch 11. Because the light-receiving element 41 is separated from the outside of the main body 2, it is not readily influenced by changes in the indoor environment. Because the printed wiring 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 printed wiring board 40 on which is the controller thereof can be easily carried out.
