The fixing panel 133 has an arc shape to correspond to the circumference of the lens 120. As the fixing panel 133 is coupled to the base panel 40, the light emitting devices 131 of the first light emitting unit 130 correspond to the optical straight part 121. In addition, as the light emitting elements 131 of the first light emitting unit 130, light emitting devices 131 having different colors of light may be applied.

In addition, a second light emitting unit 140 in which the light emitting element 141 is disposed may be disposed around the lens 120 so as to avoid the optical straight portion 121. A portion corresponding to the second light emitting unit 140 of the lens 120 diffuses the light irradiated from the second light emitting unit 140 to spread the light along the circumferential direction of the lens 120.

The second light emitting unit 140 may include an installation panel 143 disposed around the lens 120 to avoid the optical straight part 121 and to which the light emitting elements 141 are coupled. A fixing protrusion (not shown) may be formed on the installation panel 143 so that the light emitting device 141 may be disposed.

Since the installation panel 143 is coupled to the base panel 40, the light emitting devices 141 of the second light emitting unit 140 may be stably disposed at the correct position.

As the light emitting device 141 of the second light emitting unit 140, a single color light emitting device 131 capable of irradiating light of one color may be applied. For example, the light emitting devices 141 of R (Red), G (Green), and B (Blue) colors may be applied to the second light emitting unit 140. In this case, various colors may be realized by supplying power to some or all of the light emitting devices 141 of the second light emitting unit 140.

In addition, the multi-color light emitting device 131 capable of emitting two or more colors may be used as the light emitting device 141 of the second light emitting unit 140. When the light emitting device 141 is a multicolor device, various colors may be produced in the reflective housings 111 and 113 as colors emitted from the light emitting devices 141 are mixed.

A plurality of bosses are formed at positions corresponding to the fixing panel 133 and the installation panel 143 in the base panel 40, and fastening holes are formed in the fixing panel 133 and the installation panel 143 to correspond to the corresponding bosses. This may be formed. The coupling structure of the fixing panel 133 and the installation panel 143 may be variously formed.

The operation of the air cleaner including the display device according to the present invention configured as described above will be described.

When the air cleaner is operated, power is supplied to the fan device 60. At this time, as the centrifugal fan is rotated, the air sucked through the suction part 31 is filtered while passing through the filter part 20. The air filtered by the filter unit 20 is discharged through the discharge unit 55 to purify the indoor air.

6 is a perspective view illustrating a traveling direction of light in the display device.

Referring to FIG. 6, power is supplied to the first light emitting unit 130 by the controller. The controller supplies power to the light emitting device 131 corresponding to the function display unit 123. At this time, since the optical straight portion 121 is formed in a stepped groove shape, the light irradiated from the light emitting element 131 is transmitted straight through the optical straight portion 121. The light transmitted through the optical straight part 121 may appear to form light on the function display unit 123 as the refractive index of the function display unit 123 changes, so that the user may recognize the function of the function display unit 123. Will be.

In addition, when the color of the light emitting device 131 of the first light emitting unit 130 is different, each function display unit 123 may have different colors and symbols and characters.

At the same time, power is supplied to some or all of the light emitting devices 141 of the second light emitting unit 140 by the controller. Since some or all of the light emitting devices 141 scan light on a smooth outer surface of the lens 120, light is diffused along the circumferential direction of the lens 120. In this case, the light diffused along the circumferential direction of the lens 120 is diffusely reflected by the reflective layers of the reflective housings 111 and 113 to implement various kinds of lighting effects on the inner surfaces of the lens 120 and the reflective housings 111 and 113. It becomes possible.

For example, when the user presses the pollution degree display button through the operation unit 35, the control unit measures the pollution level in the room. At this time, the control unit is pre-set several steps according to the pollution degree.

If the controller determines that the indoor pollution degree is good, the controller supplies power to the light emitting device 141 irradiating the B color from the second light emitting unit 140 to color the B to the reflective housings 111 and 113. The lighting effect of can be implemented. In addition, when it is determined that the indoor pollution degree is about medium, the control unit may supply power to the G color light emitting element 131 from the second light emitting unit 140 to implement the G color lighting effect. In addition, when it is determined that the indoor pollution level is the highest level, the controller may supply power to the R color light emitting device 141 from the second light emitting unit 140 to implement an R color lighting effect. In addition, power may be supplied to some of the light emitting devices 131 of the second light emitting unit 140 to implement more various lighting colors.

In addition, the control unit may adjust the illuminance of the second light emitting unit 140 in various stages according to the pollution degree of the room to implement lighting effects with light of various brightness in the lens 120 and the reflective housings (111, 113).

As such, the display device 100 may display a predetermined function through the function display unit 123, and may display various degrees of display of the predetermined function and a progress state through the lens 120 and the reflective housings 111 and 113. .

In addition, the display device 100 may be a variety of devices such as filter replacement time of the air purifier, cold / hot water temperature or filter replacement time of the water purifier, hot water temperature of the bidet, washing water temperature of the washing machine or degree of washing (dehydration and rinsing). The function can be displayed with lighting.

Since the present invention can produce a variety of designs and lighting effects in a variety of ways, there is a significant industrial applicability.
