Abstract
Description
- The present invention relates to an indoor unit of an air conditioner and a method for manufacturing thereof.
- Recently, the design of the front panel of an indoor unit of an air conditioner has been improved by painting thereon and the like. However, if painting is simply applied on the front surface of the front panel of an indoor unit, there is a risk that its design may be hampered by a scratch on painting during installation of the indoor unit. Consequently, a technique that painting is applied on the reverse side of a transparent front panel has been suggested (for example, refer to Japanese Patent Application 2002-355175).
- Incidentally, a front panel is typically integrally molded with a mounting portion (such as a clip and/or a hinge) attached to the main body. However, when a transparent front panel is molded in this manner and the panel is given a color scheme or pattern on the reverse side surface and the mounting portion thereof, it often creates a difference in visual effects between a portion of the front side corresponding to the mounting portion and the remaining flat portion of the front side. In addition, when this difference in visual effects is excessively large, the design of the front panel as a whole may be hampered.
- An object of the present invention is to obviate a risk that the design of the front panel and the like of an indoor unit may be hampered by a mounting portion and the like attached to the main body.
- An indoor unit of the air conditioner according to a first aspect of the present invention comprises a main body, a front panel, and a design panel. The front panel is opaque and is integrally molded with a mounting portion. Note that this mounting portion is provided for mounting the front panel to the front portion of the main body, and comprises, for example, a hinge (which enables the front panel to open and close) and/or a clip. The design panel is transparent and is attached to the front panel. Additionally, this design panel is provided with a design layer on the reverse side thereof. Note that this design layer is at least given a color scheme. Additionally, this design layer may further be given a pattern.
- Here, the design panel is attached to the front panel. Additionally, the front panel is opaque as in conventional panels. Consequently, the mounting portion cannot be seen from the front of indoor unit. Thus, it is possible to obviate a risk that the design of the front panel of the indoor unit and the like may be hampered by the mounting portion and the like attached to the main body.
- An indoor unit of the air conditioner according to a second aspect of the present invention is the indoor unit of the air conditioner according the first aspect of the present invention, wherein the design panel is attached to the front panel at a peripheral portion of the design panel. Note that, in this case, the design panel is attached to the main body by a method as fitting with a clip, screwing, fusion, bonding, adhesion, and the like.
- Here, the design panel is attached to the front panel at a peripheral portion of the design panel. Therefore, it is possible to maintain the design of at least the main portion of the design panel.
- An indoor unit of the air conditioner according to a third aspect of the present invention comprises a main body, a front panel, and a mounting portion. The front panel is transparent and is disposed at the front portion of the main body. Additionally, this front panel is provided with a design layer on the reverse side thereof. Note that this design layer is at least given a color scheme. Additionally, this design layer may further be given a pattern.

Thisdecoration panel 83 is formed from a transparent resin, and as shown in Figure 16, acoated portion 262 which covers the entirety of the reverse side thereof is provided with apainting layer 27b which is given a color scheme, pattern, and the like. Thispainting layer 27b is formed by applying painting on the entire reverse side of thedecoration panel 83. Note that thisdecoration panel 83 is integrally molded with the mountingclips decoration panel 80 to be attached to thefront panel 26b. - Next, the method for manufacturing the
indoor unit 2 according to the second embodiment is described. Note that the method for manufacturing theindoor unit 2 according to the second embodiment is entirely the same as the method manufacturing the indoor unit according to the first embodiment, excepting manufacturing of the indoor unit casing. Therefore, only manufacturing of the indoor unit casing is described in this embodiment. -
Step S 1 for manufacturing theindoor unit casing 23a is, as shown in Figure 10, constituted by step S 10 for manufacturing thefront grill 25a, step S 11 for manufacturing thebottom frame 24, step S20 for manufacturing thefront panel 26b, and step S21 for manufacturing thedecoration panel 83. - In step S 10 for manufacturing the

Note that in step S20 for manufacturing thefront panel 26b, the hinge 74 (for attaching to thefront grill 25a) is integrally molded therewith. - Step S21 for manufacturing the
decoration panel 83 is constituted by step S22 for molding thedecoration panel 83 and step S23 for applying painting. In step S20 for molding thedecoration panel 83, thedecoration panel 83 is molded from a transparent resin material, and thus thetransparent decoration panel 83 is manufactured. Note that a resin material such as a transparent ABS, polystyrene, and the like is used as a transparent resin material in this invention. In addition, here, the mountingclips front panel 26b) are integrally molded with thedecoration panel 83. In step S23 for applying painting, painting is applied on the entire reverse side of thedecoration panel 83. By this step S23 for applying painting, thepainting layer 27b which is given a color scheme, pattern, and the like is provided in close contact with thecoated portion 262 of the reverse side of thedecoration panel 83. Note that, instead of painting, printing may be applied on the reverse side of thedecoration panel 83. - With the
indoor unit 2 of theair conditioner 1 according to the second embodiment, thedecoration panel 83 is attached to thefront panel 26b. In addition, thefront panel 26b is colored. Therefore, thehinge 74 cannot be seen from the front of theindoor unit 2. Thus, it is possible to obviate a risk that the design of thefront panel 26a of theindoor unit 2 may be hampered by thehinge 74. - The
decoration panel 83 according to the second embodiment is integrally provided with the mountingclips front panel 26b. However, the attachment mode of thedecoration panel 83 to thefront panel 26b is not limited to the above manner. For example, as shown in Figure 13, thedecoration panel 84 may be attached to thefront panel 26b by fusion. In this case, thedecoration panel 84 is provided with a projection at a peripheral portion thereof, and afront panel 26c (unlike thefront panel 26b, the front side of thefront panel 26c is flat without a step, however, attaching thedecoration panel 84 to thefront panel 26c will create a step) is provided with a hole suitable to the shape of the projection at a position corresponding to position of the projection. In addition, thefront panel 26c needs to be provided with a inlet port for thefilters front panel 26b. In addition, as shown in Figure 14, thedecoration panel 80 may be attached to thefront panel 26b by screws. In this case, it is preferable that the screws be threaded at a peripheral portion of thedecoration panel 80 so that the design of thedecoration panel 80 will not be hampered. Further, as shown in Figure 15, it is conceivable that thedecoration panel 81 is attached to thefront panel 26b by bonding. Also in this case, attention should be paid not to hamper the design of thedecoration panel 81. - Note that all the
decoration panels painting layer 27b is provided on thecoated portion 262 of the reverse side of thedecoration panels - The indoor unit of the air conditioner according to the present invention obviates a risk that the design of the front panel of the indoor unit may be hampered by a hinge.
