Description

  • The present invention relates to an air conditioner, particularly an air conditioner with an illumination panel on the body.
  • In general, air conditioners are devices that heat/cool a room, using a refrigeration cycle of a refrigerant which is constructed by a compressor, a condenser, an expansion valve, and an evaporator, or that purifies air, using a filter, in order to create a more pleasant indoor environment for users.
  • The air conditioners have an air intake port through which indoor air is sucked and an air discharge port through which the air conditioned in the air conditioners is discharged to the outside. The air conditioners may include a heat exchanger therein which exchanges heat between a refrigerant and air.
  • The air conditioners usually keep placed in a room or a living room, occupying a space, usually only for cooling and heating, which is the main function, and the period of actual use is relatively shorter than those of other household appliances.
  • When a lamp is installed in the air conditioners, the decorative beauty of the air conditioners can be improved by the lamp and the light from the lamp can indirectly illuminate the room. In the air conditioners, a portion of the indoor unit may be a transparent part, and when a lamp is disposed behind the transparent part, the light from the lamp can be radiated to the front of the transparent part through it.
  • However, when a lamp is disposed behind the transparent part and radiates light forward to the transparent part in the air conditioners, there is a problem in that the lamp may be seen through the transparent part when the lamp is turned off and the light radiated forward from the lamp has a difficulty in making a clear illumination pattern having a specific shape because it spreads wide to the front of the transparent part.
  • An object of the present invention is to provide an air conditioner that can make a clear illumination pattern.
  • In order to achieve the object of the present invention, an air conditioner according to claim 1 includes: a body taking indoor air inside through an air intake port, conditioning the air, and discharging the air to an air discharge port; and an illumination panel on the body, in which the illumination panel includes: an illumination panel base; a first cover on the illumination panel base; a light emitting unit emitting light outward between the illumination panel base and the first cover, between the illumination panel base and the first cover; a second cover having a gap between the first cover and the second cover; and a reflector reflecting the light emitted from the light emitting unit to the front of the first cover through the gap.
  • The reflector may have a space therein where the light emitting unit is disposed.
  • The reflector may be disposed to surround the portion between the illumination panel base and the first cover.
  • The reflector may be disposed to surround the outer circumference of the first cover.
  • The inner diameter of the reflector may be larger than the outer diameter of the first cover.
  • Only a portion of the front of the first cover may face the reflector.
  • The front of the first cover may be rounded to be convex forward, and the reflector may have at least one reflective side reflecting light toward the front of the first cover.
  • The reflector may have a plurality of reflective sides sequentially reflecting the light emitted from the light emitting unit.
  • The reflective sides may include: a first reflective side reflecting forward the light emitted from the light emitting unit; and a second reflective side reflecting the light, which reflects from the first reflecting side, toward the front of the first cover.
  • The second cover may have an opening that exposes the first cover to the outside.
