Description

  The present invention relates to an indoor unit of an air conditioner, and more particularly to an indoor unit of an air conditioner having an improved display structure.

  In recent years, with the diversification of operation modes of air conditioners, a large number of illuminants with different emission colors are caused to emit light depending on the operation state such as cooling operation, heating operation, dehumidification operation, air cleaning operation, etc. The user is able to confirm the driving state by the difference.

  For example, a panel is provided in front of the front suction port, and a suction port is formed at the lower part of the panel. A decorative panel using a translucent plate is arranged in the suction port portion in the width direction, and the suction port portion The display unit in which the whole emits light and the light-emitting device is arranged is arranged in the front part between the suction port and the outlet. In such a conventional wall-mounted air conditioner indoor unit, when a display unit is provided on the front panel portion, the LED used for displaying the driving state is expensive and expensive in order to ensure visibility when the lighting is turned on. It is necessary to use a thing with brightness. In addition, in order to prevent malfunction due to noise such as inverter fluorescent lamps, it is necessary to use a filter material that transmits only infrared rays in the light receiving portion of a wireless remote controller that uses infrared rays (Patent Document 1).

However, the high-brightness LED used in Patent Document 1 is more expensive than a general LED, and a material that transmits only infrared light is more expensive than a general material.
