Description

  The present invention relates to an air conditioner, and more particularly to a configuration of a display unit.

  The air conditioner has, for example, a display unit that displays an operating state or the like on the lower side of the front panel. The display unit is provided with a design layer on which the characters and figures to be displayed are printed on the back surface of the transparent sheet, and an LED serving as a light source is provided on the back surface side of the transparent sheet, and the light emitted from the LED is emitted. Only a printing part to be displayed among a large number of printing parts is allowed to pass, and an operation state or the like is displayed outside the casing (see Patent Document 1).

  However, since the back surface of the transparent sheet is subjected to multi-layer printing that constitutes characters or figures to be displayed, the light emitted from the LED and passing through the design layer causes a diffusion phenomenon when passing through the transparent sheet. The characters and graphics to be displayed cannot be clearly displayed. Also, since a transparent resin is used for the transparent sheet, the light reflectance and reflection amount are different compared to the front panel made of an opaque resin material, resulting in a slight difference in color between the display and the front panel. There was a problem that made people feel uncomfortable.

  In order to cope with the above-mentioned problems, when printing was performed on the front surface of the transparent sheet, the distance between the LED and the printing surface was increased, and when the installation position of the LED and the printing surface was displaced, the light was emitted from the LED. There is a possibility that light is not accurately irradiated onto the printing surface, and display of displayed characters, figures, and the like becomes unclear.

JP 2006-91602 (page 4, FIG. 2)

  In view of the above-mentioned problems, the present invention provides a character to which light emitted from an LED should be accurately displayed even when a multi-layered design layer is provided on the front surface of a transparent sheet or a transparent display plate constituting the display unit. Another object of the present invention is to provide an air conditioner including a display unit that can clearly display characters, figures, and the like to be displayed so as to pass through the figure and the like.

The element 18a is mounted, and a plurality of LED elements 18b for character display are mounted on the lower part of the front surface. The light emitted from the LED elements 18a for seven segments and the LED elements 18b for character display is transmitted through the above-described light passing holes 15c and Numbers and characters are displayed on the front surface of the display board 13 through the light passage hole 15d.

  A display board 13 made of a transparent material and integrated with the design plate 12 is assembled to the display panel 14 as shown in FIG. As shown in FIG. 5 (B), the display panel 13 is formed of a base material 13a that is formed in a gentle curved shape in the vertical direction and has transparency, and is formed in a U-shape at the bottom of the back surface of the base material 13a. And a pair of left and right locking claws 13c, a locking claw 13d, and a locking claw 13f are provided on the upper surface of the rear surface, the substantially central portion of the rear surface, and the lower surface of the rear surface. The part is provided with a pair of alignment projections 13e formed in a trapezoidal shape for alignment with the substrate holder front plate 15.

  As shown in FIG. 5B, the display panel 14 includes a base material 14a made of a resin material formed in a frame shape, and a rectangular light transmission window 14b is formed inside. A pair of left and right horizontally elongated locking holes 14d corresponding to the locking claws 13c of the display board 13 are formed in the upper part of the base material 14a, and the right panel 1c is locked above the locking holes 14d. A pair of left and right L-shaped locking claws 14c are provided.

At this time, a pair of left and right alignment protrusions 13e formed on the back surface of the display board 13 are aligned with the alignment portions 15j formed at the left and right corners where the intermediate wall 15f and the lower wall 15g of the substrate holder front plate 15 contact each other. And the upper end surface of the locking claw 13f of the display plate 13 is abutted against the lower wall 15h of the lower end of the substrate holder front plate 15 so that the display panel set 10a is aligned at an appropriate position in the horizontal direction and the vertical direction. In addition, the front surface of the locking claw 13f is abutted against the lower wall 15h to prevent the substrate holder 10b from being displaced upward.

  The design plate 12 is provided on the front surface of the display plate 13 by assembling the display plate 13 assembled to the display panel 14 and the substrate holder front plate 15 of the substrate holder 10b at appropriate positions in the horizontal direction and the vertical direction. The light from the seven-segment LED element 18a arranged corresponding to the light passage hole 15a of the substrate holder front plate 15 and the light from the character display LED element 18b arranged corresponding to the light passage hole 15b are also received. The display part of the design plate 12 can be accurately passed, and the display on the display unit 10 can be performed more clearly. In the present invention, the display panel 14 is formed separately from the front panel 1a and is attached to the right panel 1c. However, the display panel 14 may be formed integrally with the front panel 1a.
