The temperature display 15a is provided by the number of each temperature, and is printed (described) on the design surface 11a of the acrylic plate 11 with an interval in the longitudinal direction of the acrylic plate 11.

  In addition, light-emitting display portions 16a and 16b (collectively referred to as light-emitting display portion 16) are provided corresponding to the respective displays indicating the operating states. Specifically, the light emission display unit 16 is provided on each of the displays 15 indicating the driving state, and the display 15 and the light emission display unit 16 correspond one-to-one. Here, the example in which the light emitting display unit 16 is provided on each of the displays indicating the driving state has been described. However, the light emitting display unit 16 and the display indicating the driving state may be provided so as to be visually associated with each other. .

  The light emitting display part 16 is comprised by the notch which notched the design surface back surface 11b side of the acrylic board 11. FIG. The inner peripheral surface of the notch is constituted by an inclined surface 19a having an inclination angle of about 45 ° with respect to the design surface back surface 11b and a vertical surface 19b substantially perpendicular to the design surface back surface 11b. And in the lower end surface of the acrylic board 11, directly under each light emission display part 16 is extended below and becomes the protrusions 17a and 17b (it is called the protrusion 17 when it generically refers). The LED 13 is disposed on the display substrate 12 so as to face the protrusion 17. That is, the light emitting display unit 16 and the LED 13 are provided in a state of being associated with each other.

  In the display device 10 configured as described above, when the LED 13 is turned on, the light emitted from the LED 13 is irradiated to the protrusion 17 directly above the LED 13, and the light irradiated to the protrusion 17 passes through the acrylic plate 11 in the vertical direction. The light emitting display unit 16 is caused to emit light by transmitting vertically upward. That is, the light irradiated to the notches constituting the light emitting display unit 16 changes the irradiation angle by a 45 ° inclination angle and illuminates the horizontal direction. That is, the horizontal direction is illuminated by changing the irradiation angle with an inclination angle of 45 °. As a result, when viewed from the front, the inside of the cutout of the acrylic plate 11 is illuminated and the light emitting display section 16 appears to shine, so that the current set temperature and ON / OFF of the power supply can be confirmed. FIG. 6 shows a state where the light emitting display unit 16a at a temperature of 25 ° C. and the light emitting display unit 16b of the power supply state display 15b emit light. It can be seen from this display that the set temperature is 25 ° C. during the current operation.

Next, the light receiving unit 20 for wireless remote control communication will be described.
FIG. 8 is an exploded perspective view of the light receiving unit 20 of the wireless remote control communication of FIG.
The light receiving unit 20 includes a light receiving substrate 21, a light receiving unit holder 22 that holds the light receiving substrate 21 on the back side, and a translucent light receiving unit surface cover 23 that covers the front surface of the light receiving unit holder 22. A cutout is formed in the location of the light receiving section 20 (lower right portion in this example) on the outlet surface 9 so that a part of the front surface of the light receiving section surface cover 23 is located in the cutout section. It has become. Here, the color of the air outlet surface 9 and the light receiving unit 20 is unified in black so that the light receiving unit 20 does not stand out. And the positional relationship of the light-receiving part 20 and the acrylic board 11 is adjusted so that the light-receiving part 20 may be settled in the acrylic board 11 of the display apparatus 10, when it sees from the front of an air conditioner.

  In the light receiving unit 20, a control signal transmitted from a remote controller (not shown) is received by a light receiving element (not shown) provided on the light receiving substrate 21, and the control signal is sent to the control unit 2 to control signal. Control according to is performed.

  Thus, since the display (temperature display 15a, power supply state display 15b) which shows a driving | running state is described in the design surface 11a of the acrylic board 11 which covers the front surface of the light-receiving part 20 so to speak, when it sees from the design surface front surface The presence of the light receiving unit 20 is not bothered, leading to an improvement in design. Further, since the display device 10 is in front of the design surface, it is easy to check the operating state. That is, while the light receiving unit 20 is provided on the front side of the design surface, the light receiving unit 20 does not impair the design of the front surface of the design surface, and the display of the display device 10 makes it easy to see the display of the operating state at a glance. It has the structural effect of being able to. In addition, the design surface 11a of the acrylic plate 11 is configured to reflect light of external illumination such as a fluorescent lamp, making the light receiving unit 20 more difficult to see.

  Further, considering the reception sensitivity of the light receiving unit 20, in the conventional patent document 1, the light receiving unit is arranged in front of the design surface of the air conditioner so that it can be directly seen from the front, and there is no shielding object between the remote controller and the remote controller. On the other hand, in the structure of the first embodiment, the acrylic plate 11 is disposed in front of the light receiving unit 20. However, since the acrylic plate 11 is made of a translucent material that does not hinder the reception sensitivity of wireless remote control communication, even if the acrylic plate 11 is arranged on the front surface of the light receiving unit 20, the communication function is not caused. Can also be maintained. That is, there is a functional effect that the reception sensitivity of the conventional wireless remote control communication can be maintained while the light receiving unit 20 and the display device 10 are provided in front of the design surface.

  In addition, since the display device 10 and the light receiving unit 20 are separated, there is no structural restriction, which leads to a generous structural design. For example, since the light receiving unit 20 is away from the display device 10, the display device 10 can have a structure in which only the acrylic plate 11 is raised. In addition, by using only the same shape of the acrylic plate 11 as the display location, it is possible to further improve the visibility of the display location.

  In the first embodiment, the light emitting display unit 16 is configured by providing a cutout in the acrylic plate 11 and emitting light from the cutout. However, the configuration of the light emitting display unit 16 is not limited to this configuration. Absent. In addition, for example, the LED 13 is arranged behind the temperature display 15a and the power supply status display 15b of the acrylic plate 11, and the LED 13 is turned on to light the temperature display 15a and the power supply display 15b in front of the light emitting display unit. May be configured.

  In the first embodiment, the set temperature and the power ON / OFF are displayed as the operation state. However, the display content is not limited to this and is arbitrary.
