Definitions

  • the present invention relates to an indoor unit of an air-conditioning apparatus and, more specifically, to an indoor unit of an air-conditioning apparatus mounted on a wall surface.
  • an indoor unit of an air-conditioning apparatus includes a fan having a body formed of a housing and an air course formed therein, and a heat exchanger arranged in the air course accommodated therein.
  • a gloss coating is applied on the surface of an opening-and-closing panel (the same as a front grill) to be arranged in the front, and a transparent decorative panel applied with texturing is provided in the front of the coated surface in order to enhance the design characteristics (for example, Patent Literature 1).
  • Patent Literature 1 JP2004-257619A (P4, Fig. 2 )
  • Patent Literature 1 has a problem such that the design characteristics cannot be enhanced satisfactorily as described below.
  • the invention is intended to provide an indoor unit of an air-conditioning apparatus having improved design characteristics.
  • An indoor unit of an air-conditioning apparatus including: a frame body as a framework; side panels mounted respectively on both side surfaces of the frame body; a front opening-and-closing panel mounted in the front of the frame body so as to be openable and closable; L-shaped panels mounted respectively near the side panels so as to straddle a lower area of the front of the frame body below the front opening-and-closing panel and a front-side area of a bottom surface; and a bottom panel mounted between the L-shaped panels on the bottom surface of the frame body.
  • the invention includes the frame body which is the framework of the body of the indoor unit, the side panels, the front opening-and-closing panel, the L-shaped panels, and the bottom panel mounted respectively on the surfaces of the frame body. Therefore, since the respective panels can be formed into simple shapes apart from the shape of the frame body, a molding method which improves design characteristics (for example, heat and cool molding) can be employed, and hence the surfaces of these panels can be formed into high-gloss weldless surfaces.

  • the respective drawings are diagrammatically illustrated, and the shapes and the sizes of the respective members are not limited to those illustrated in the drawings.
  • the same parts or corresponding parts of the respective drawings are designated by the same reference numerals and parts of the description may be omitted.
  • an indoor unit of an air-conditioning apparatus (hereinafter, referred to as "indoor unit”) 100 is configured to cause indoor air taken from an inlet opening 2 formed on an upper surface of a frame body (the same as a “framework”) 1 to pass through a heat exchanger 6 and to be heat-exchanged (conditioned), and deliver the air after being heat-exchanged (conditioned) (hereinafter, referred to as "conditioned air”) indoors from an outlet opening 3 formed on the frame body 1 so as to extend to a substantially bottom surface via an air course 4 by the rotation of a fan 7.
  • the air course 4 is defined by a front air course member 8 on the front (left) side of the body and a back air course member 9 on the back (right) side of the body, and the front air course member 8 is provided with a horizontal wind-direction control panel 10.
  • the outlet opening 3 is provided with a front vertical wind-direction control panel 11a and a bottom vertical wind-direction control panel 11b, which are configured to close the outlet opening 3 in an area on the front side of the body and an area on the lower side of the body, respectively.
  • the frame body 1 is the frame body (framework) of a rectangular parallelepiped shape, and is formed with the inlet opening 2 over part of a body top surface 1A having a rectangular flat surface and the outlet opening 3 extending so as to straddle part of a body bottom surface 1 B having a rectangular flat surface and part of a body front surface 1 F having a rectangular flat surface.
  • a left L-shaped panel 17L and a right L-shaped panel 17R having an L-shaped cross section are attached so as to straddle part of the body bottom surface 1 B and part of the body front surface 1 F on opposite sides of the outlet opening 3 when viewed from the front, and a center bottom panel 17C having a rectangular flat surface is mounted to the back side of the outlet opening 3 of the body bottom surface 1 B.
  • Mounted to an area close to the body front surface 1 F of a left body surface 1 L is a left side panel 16L having a rectangular flat surface
  • mounted to an area close to the body front surface 1 F of a right body surface 1 R is a right side panel 16R having a rectangular flat surface.
  • the left side panel 16L projects leftward by an amount corresponding to a difference in level g16 with respect to the left body surface 1 L
  • the right side panel 16R projects rightward by an amount corresponding to the difference in level g16 with respect to the right body surface 1 R.
  • the center bottom panel 17C projects downward and rightward from the body bottom surface 1 B by an amount corresponding to a difference in level g17 (see Figs. 3A, 3B, and 3C ).
  • a front opening-and-closing panel 15 (the same as a grill) is attached to a body front opening 5 formed on the body front surface 1 F of the frame body 1 so as to be openable and closable.
  • the front opening-and-closing panel 15 includes a panel frame body 13 and a panel design surface 14 integrated into one piece.
  • the panel frame body 13 includes a front frame body portion 13C as the frame body (framework) having a rectangular flat surface, a left body frame surface 13L having a rectangular flat surface and a right body frame surface 13R having a rectangular flat surface formed respectively on a left edge and a right edge of the front frame body portion 13C and both projecting backward, and has a substantially angular C-shape (substantially a square bracket shape) in cross section.
  • the panel design surface 14 has a rectangular shape, and is a substantially flat surface having an inclined rim which improves design characteristics around the periphery thereof.
  • combining locking portions 13a for combining the panel design surface 14, and tilt centers 13b supported so as to be tiltable.
  • formed on the back side (the surface which is not visible from the outside) of the panel design surface 14 are combining locked portions 14a configured to be locked with the combining locking portions 13a and tilt bearings (not illustrated) which tiltably support the tilt centers 13b so as to be tiltable. Therefore, the panel frame body 13 and the panel design surface 14 are integrated only by pressing the panel design surface 14 against the front side of the front frame body portion 13C, so that the front opening-and-closing panel 15 is formed.
  • the front opening-and-closing panel 15 When the front opening-and-closing panel 15 is molded integrally, a specific draft angle for plastic molding is necessary, and hence the front opening-and-closing panel 15 cannot be formed into a rectangular parallelepiped, which is a simple shape, (a rectangular parallelepiped, one direction of which is longer, or a quadratic prism).
  • the panel design surface 14 of a simple shape is achieved by forming the front opening-and-closing panel by combining two components, namely, the panel frame body 13 and the panel design surface 14 in combination. Therefore, formation by heat and cool molding is enabled as described later and, with such molding, the high-gloss surface with no weld line is obtained.
  • the frame body 1 is formed into the framework instead of the housing formed of such face plates, and face plates are mounted to the framework.
  • face plates such as the left side panel 16L, the right side panel 16R, the left L-shaped panel 17L, the center bottom panel 17C, and the right L-shaped panel 17R (hereinafter, these panels may collectively or individually be referred to as "separate-piece design panel") are formed of a rectangular flat surface, formation by the heat and cool molding is enabled as described later and, with such molding, the high-gloss surface with no weld line is obtained.
  • the panel design surface 14 and the separate-piece design panel having a simple shape, can be manufactured by the heat and cool molding, and hence are manufactured by the heat and cool molding. Therefore, in the case of general molding, even when the design surface of the die is finished into a mirror surface, there is a limit on gloss of the molded product. In contrast, since the panel frame body 13 and the panel design surface 14 are manufactured by the heat and cool molding, they have high-gloss surfaces.
  • the panel design surface 14 which is easily visible by a user, is formed into a high-gloss surface which adds a high-quality design
  • the separate-piece design panels (the left side panel 16L, the right side panel 16R, the left L-shaped panel 17L, the center bottom panel 17C, and the right L-shaped panel 17R) as well as the front vertical wind-direction control panel 11a and the bottom vertical wind-direction control panel 11 b adjacent thereto are manufactured by the heat and cool molding, whereby a high-gloss design with a sense of unity is realized in an area easily visible by the user.
  • the left body surface 1 L and the right body surface 1 R of the frame body being not easily visible by the user, are positioned at a level lower than the left side panel 16L and the right side panel 16R respectively by an amount corresponding to the difference in level g16 and, furthermore, are applied with texturing. Therefore, the left body surface 1 L and the right body surface 1 R being applied with texturing give an impression of being set back and, in contrast, the high-gloss left side panel 16L and right side panel 16R give an impression of protruding to the front, so that the high-gloss is further accentuated.
  • the heat and cool molding is also referred to as “weldless molding”, and is a molding method used in the injection molding of thermoplastic resin, which heats the surface of the die (hereinafter, referred to as "cavity surface”) to temperatures higher than a glass transition temperature (or load-deformation temperature) of the resin to delay cooling and solidifying the injected resin.
  • a glass transition temperature or load-deformation temperature
  • the panel design surface 14 and the separate-piece design panels are formed into simple shapes, so that the die heating pipes and the die cooling pipes can be arranged uniformly at regular spacings, and hence the panel design surface 14 and the separate-piece design panels are manufactured by the heat and cool molding.
  • the left side panel 16L and the right side panel 16R both have an L-shape cross section, they have a shape including simple-shaped rectangular flat surfaces orthogonal to each other and not including any hook or wall. Therefore, uniform arrangement at regular spacings of the die heating pipes and the die cooling pipes is enabled.
  • the right L-shaped panel 17R having an L-shape cross section is formed with a corner notch 17a at a corner portion thereof, and a remote-control receiving window 18 having an L-shape cross section is mounted to the corner notch 17a.
  • the remote-control receiving window 18 is configured to be fitted from the outside of the right L-shaped panel 17R inward (toward the inside of the frame body 1), and is held from the inside toward the outside by a operation indicator light-window component 19 formed with an corner notch 19a.
  • the remote-control receiving window 18 having the L-shaped cross section, deterioration of receiving performance which may occur when the remote-control receiving window has a single surface configuration resulting from the indoor unit 100 formed into the parallelepiped shape is avoided, and the same receiving performance as the remote-control receiving window having a single surface configuration in the indoor unit having shapes other than the parallelepiped is ensured.
  • the remote-control receiving window of the related art is fitted from the inside of the product and is fixed by claw shapes formed inside the frame body.
  • the remote-control receiving window is configured to be fitted from the outside and held by the operation indicator light-window component 19 from the inside instead of the fixation with the claws.
  • 1 frame body, 1A: body top surface, 1 B: body bottom surface, 1 F: body front surface, 1 L: left body surface, 1 R: right body surface, 2: inlet opening, 3: outlet opening, 4: air course, 5: body front opening, 6: heat exchanger, 7: fan, 8: front air course member, 9: back air course member, 10: horizontal wind-direction control panel, 11 a: front vertical wind-direction control panel, 11b: bottom vertical wind-direction control panel, 13: panel frame body, 13C: front frame body portion, 13L: left frame body surface, 13R: right frame body surface, 13a: combining locking portions, 13b: tilt center, 14: panel design surface, 14a: combining locked portion, 15: front opening-and-closing panel, 16L: left side panel, 16R: right side panel, 17C: center bottom panel, 17L: left L-shaped panel, 17R: right L-shaped panel, 17a: corner notch, 18: remote-control receiving window, 19: operation indicator light-window component,
