- Patent Literature 1 JP 2008-147610 A
- the frame body defines each region of the wavelength conversion layer that is irradiated with light emitted from a corresponding one of the plurality of light emitting elements.
- Such a light emitting device cannot meet a demand for variations of indication in which lights emitted from the plurality of light emitting devices are indicated in a superimposed manner or light emitted from one of the plurality of light emitting elements is exclusively indicated.
- An indicating device includes:
- a part of the indicating part adjacent to the first light emitting element relative to the partition wall is irradiated with the light emitted from the first light emitting element and the light emitted from the second light emitting element in a superimposed manner.
- a part of the indicating part adjacent to the second light emitting element relative to the partition wall is irradiated only with the light emitted from the second light emitting element. This makes it possible to increase variations of indication.
- the indicating part includes:
- the longest distance between the first light emitting element and the first region is shorter than the shortest distance between the second light emitting element and the first region. This makes, even in a case where the first light emitting element and the second light emitting element emit light having approximately the same light emission intensity, light reaching the first region from the first light emitting element larger in illuminance than light reaching the first region from the second light emitting element. This allows the light emission color of the first light emitting element to be clearly indicated in the first region.

- the light-shielding part of the cover is disposed at the position corresponding to the operation part of the switch, so that the light-shielding part allows a user to clearly recognize the position of the operation part of the switch.
- the first region irradiated with the light emitted from the first light emitting element is higher in average illuminance than the first region irradiated with the light emitted from the second light emitting element.
- the first region irradiated with the light emitted from the first light emitting element is higher in average illuminance than the first region irradiated with the light emitted from the second light emitting element, so that the light emission color of the first light emitting element can be clearly indicated in the first region.
- the first light emitting element is a single-color LED
- the second light emitting element is a multi-color LED capable of emitting light of a plurality of colors.
- An air conditioner according to the present disclosure includes the indicating device.
- the air conditioner has a plurality of operating modes, and a light emission mode of the indicating device changes in accordance with each of the operating modes.
- the light emission mode of the indicating device changes in accordance with each of the operating modes of the air conditioner, so that the user can easily recognize each of the operating modes of the air conditioner.

- the light receiving lens 60 receives light (for example, infrared rays) from an external operation device such as a remote controller to guide the light toward the light receiving element 35 provided on the printed circuit board 30.
- the front cover 70 is attached to the top grille 11 so as to cover the first hole 11a of the top grille 11 and the indicating part 51 of the switch cover 50 disposed in the first hole 11a.

- Fig. 4 is a plan view of the region around the indicating device 20 according to the present embodiment.
- Fig. 4 illustrates a state where the front cover 70 (illustrated in Fig. 2 ) is removed. That is, in Fig. 4 , the switch cover 50 is exposed.
- the indicating part 51 includes a first region 52 irradiated with the light emitted from the first light emitting element 31 and the light emitted from the second light emitting element 32, and a second region 53 irradiated only with the light emitted from the second light emitting element 32.
- the first region 52 is indicated by dot hatching
- the second region 53 is indicated by line hatching.
- the first region 52 is defined by the partition wall 42.
- the partition wall 42 having a light-shielding property can prevent the light emitted from the first light emitting element 31 from spreading to the outside of the first region 52 by limiting a region of the indicating part 51 irradiated with the light emitted from the first light emitting element 31 to the first region 52. This makes it possible to clearly distinguish between the first region 52 irradiated with the light emitted from the first light emitting element 31 and the second region 53 not irradiated with the light emitted from the first light emitting element 31 in the indicating part 51.
- the first region 52 is partially covered with the light-shielding part 72 (indicated by a long dashed double-short dashed line in the drawing) of the front cover 70.

- a longest distance L1 between the first light emitting element 31 and the first region 52 is shorter than a shortest distance L2 between the second light emitting element 32 and the first region 52.
- the longest distance L1 is a linear distance in a three-dimensional space between a point A farthest from the first light emitting element 31 in the first region 52 and the first light emitting element 31 (illustrated in a planar view in Fig. 4 ).
- the shortest distance L2 is a linear distance in a three-dimensional space between a point B closest to the second light emitting element 32 in the first region 52 and the second light emitting element 32 (illustrated in a planar view in Fig. 4 ).
- Fig. 5 is a cross-sectional view taken along line V-V of Fig. 4 .
- the first light emitting element 31, the second light emitting element 32, and the third light emitting element 33 are surrounded by the wall 41 of the lamp cover 40.
- the partition wall 42 having a light-shielding property is provided between the first light emitting element 31 and the second light emitting element 32.
- the partition wall 42 is disposed at a distance from the indicating part 51 of the switch cover 50. The partition wall 42 prevents the light emitted from the first light emitting element 31 from widely spreading and defines the first region 52 by limiting the region irradiated with the light emitted from the first light emitting element 31 in the indicating part 51.
- the partition wall 42 is smaller in dimension in a rising direction (vertical direction in Fig. 5 ) than the wall 41.
- the dimension of the partition wall 42 in the rising direction is at least 1/2 times the dimension of the wall 41 in the rising direction.
- the dimension of the partition wall 42 in the rising direction is preferably at least 2/3 times the dimension of the wall 41 in the rising direction.
- a surface of the printed circuit board 30 includes an installation region R defined by the wall 41 of the lamp cover 40.
- the partition wall 42 partitions the installation region R into a first installation region R1 and a second installation region R2.
- the first light emitting element 31 is disposed in the first installation region R1
- the second light emitting element 32 is disposed in the second installation region R2.
- the switch cover 50 includes a projecting part 54 extending from the indicating part 51 toward the operation switch 34.
- the projecting part 54 moves toward the printed circuit board 30 to press the operation switch 34 provided on the printed circuit board 30. That is, the switch cover 50 according to the present embodiment serves as an operation part that is operated by the user to operate the operation switch 34.
- the indicating part 51 of the switch cover 50 according to the present embodiment is an example of an operation part of a switch according to the present disclosure.
- the light receiving lens 60 is partially exposed to the outside from the top grille 11. Further, the light receiving lens 60 extends from the part exposed to the outside toward the light receiving element 35.
- the front cover 70 is disposed so as to cause the protrusion 71 to face the indicating part 51 of the switch cover 50. Accordingly, the light-shielding part 72 formed in the protrusion 71 is disposed at a position corresponding to the indicating part 51 serving as the operation part of the switch according to the present disclosure. Further, the protrusion 71 protrudes in a direction remote from the indicating part 51. This increases visibility of the indicating part 51 as viewed from the side.
- Fig. 6 is a diagram illustrating one light emission mode of the indicating device 20 according to the present embodiment.
- the first light emitting element 31 (illustrated in Fig. 4 ) is off, and the second light emitting element 32 (illustrated in Fig. 4 ) or the third light emitting element 33 (illustrated in Fig. 4 ) is on.
- the second light emitting element 32 irradiates the first region 52 and the second region 53 with blue emission light.
- the indicating device 20 causes, when the air conditioner is in the heating operating mode, the second light emitting element 32 to irradiate the first region 52 and the second region 53 with red emission light.
- the second light emitting element 32 irradiates the first region 52 and the second region 53 with green emission light. Further, for example, when the air conditioner is in the ventilation operating mode, the third light emitting element 33 irradiates the first region 52 and the second region 53 with white emission light.
- the combinations of the operating mode of the air conditioner and the color indicated in the second region 53 are not limited to the combinations described above.
- Fig. 7 is a diagram illustrating another light emission mode of the indicating device 20 according to the present embodiment.
- the first light emitting element 31 (illustrated in Fig. 4 ) is on, and the second light emitting element 32 (illustrated in Fig. 4 ) or the third light emitting element 33 (illustrated in Fig. 4 ) is on.
- the indicating device 20 turns on the first light emitting element 31 in addition to the second light emitting element 32 or the third light emitting element 33 to indicate that the timer has been set.
- the first region 52 is irradiated with light including green emission light emitted from the first light emitting element 31 and blue emission light emitted from the second light emitting element 32
- the second region 53 is irradiated with the blue emission light emitted from the second light emitting element 32. Accordingly, when the air conditioner is in the cooling operating mode, a bluish green color is indicated in the first region 52, and a blue color different from the color indicated in the first region 52 is indicated in the second region 53.
- the first region 52 is irradiated with light including green emission light emitted from the first light emitting element 31 and red emission light emitted from the second light emitting element 32
- the second region 53 is irradiated with the red emission light emitted from the second light emitting element 32. Accordingly, when the air conditioner is in the cooling operating mode, a reddish green color is indicated in the first region 52, and a red color different from the color indicated in the first region 52 is indicated in the second region 53.
- the first region 52 is irradiated with light including green emission light emitted from the first light emitting element 31 and green emission light emitted from the second light emitting element 32
- the second region 53 is irradiated with the green emission light emitted from the second light emitting element 32.
- the green color of the light emitted from the first light emitting element 31 may be more vivid than the green color of the light emitted from the second light emitting element 32. Accordingly, when the air conditioner is in the dehumidifying operating mode, a vivid green color is indicated in the first region 52, and a green color different from the green color indicated in the first region 52 is indicated in the second region 53.
- the first region 52 is irradiated with light including green emission light emitted from the first light emitting element 31 and white emission light emitted from the third light emitting element 33
- the second region 53 is irradiated with the white emission light emitted from the third light emitting element 33. Accordingly, when the air conditioner is in the ventilation operating mode, a whitish green color is indicated in the first region 52, and a white color different from the color indicated in the first region 52 is indicated in the second region 53.
- the indicating device 20 according to the present embodiment has the following effects.
- the first distance d1 between the first light emitting element 31 and the partition wall 42 is shorter than the second distance d2 between the second light emitting element 32 and the partition wall 42. Therefore, a part of the indicating part 51 adjacent to the first light emitting element 31 relative to the partition wall 42 is irradiated with the light emitted from the first light emitting element 31 and the light emitted from the second light emitting element 32 in a superimposed manner. On the other hand, a part of the indicating part 51 adjacent to the second light emitting element 32 relative to the partition wall 42 is irradiated only with the light emitted from the second light emitting element 32. This makes it possible to increase variations of indication for the indicating part 51.
- the partition wall 42 If the partition wall 42 is in contact with the indicating part 51 with no gap between the indicating part 51 and the partition wall 42, a part that is not irradiated with either the light emitted from the first light emitting element 31 or the light emitted from the second light emitting element 32 appears in a region of the indicating part 51 facing the partition wall 42.
- the above-described part therefore, prevents the region irradiated with the light emitted from the first light emitting element 31 and the region irradiated with the light emitted from the second light emitting element 32 from being continuous with each other.
- the indicating part 51 and the partition wall 42 are arranged at a distance from each other, so that a part of the light emitted from the second light emitting element 32 passes between the indicating part 51 and the partition wall 42 to impinge on the first region 52. This allows the first region 52 and the second region 53 of the indicating part 51 to be illuminated without interruption.
- the longest distance L1 between the first light emitting element 31 and the first region 52 is shorter than the shortest distance L2 between the second light emitting element 32 and the first region 52. This makes, even in a case where the first light emitting element 31 and the second light emitting element 32 emit light having approximately the same light emission intensity, light reaching the first region 52 from the first light emitting element 31 larger in illuminance than light reaching the first region 52 from the second light emitting element 32. This allows the light emission color of the first light emitting element 31 to be clearly indicated in the first region 52.
- the first region 52 is partially covered with the light-shielding part 72 of the front cover 70, so that the first region 52 is partially shielded from light. Accordingly, the part illuminated by the first light emitting element 31 and the second light emitting element 32 and the part shielded from light by the light-shielding part 72 are positioned adjacent to each other in the first region 52.

Accordingly, the part illuminated by the first light emitting element and the second light emitting element and the part shielded from light by the light-shielding part are positioned adjacent to each other in the first region. This makes the indicated part in the first region clear.
- The indicating device according to an embodiment further includes a switch, in which
the light-shielding part of the cover is disposed at a position corresponding to an operation part of the switch. - According to the above-described embodiment, the light-shielding part of the cover is disposed at the position corresponding to the operation part of the switch, so that the light-shielding part allows a user to clearly recognize the position of the operation part of the switch.

wall 41 is provided with apartition wall 42 having an approximately semitubular shape and projecting toward the inside of thewall 41. With the indicatingdevice 20 built up, thelamp cover 40 is disposed so as to cause thepartition wall 42 and a part of thewall 41 to surround the firstlight emitting element 31 provided on the printedcircuit board 30. - The
lamp cover 40 is formed of a monolithic component. That is, thewall 41 and thepartition wall 42 provided on thewall 41 are integrally formed. Thewall 41 and thepartition wall 42 provided on thewall 41 are made of light-shielding resin. - The
lamp cover 40 is provided with a receivinghole 43 for receiving thelight receiving lens 60. The receivinghole 43 allows a space of thelamp cover 40 adjacent to the printedcircuit board 30 and a space of thelamp cover 40 adjacent to thetop grille 11 to communicate with each other. - The switch cover 50 according to the present embodiment includes an indicating
part 51 that is translucent and has a dome shape.

A part of thelight receiving lens 60 is exposed to the outside of the indoor unit 1 (illustrated inFig. 1 ) from thesecond hole 11b of thetop grille 11. Thelight receiving lens 60 receives light (for example, infrared rays) from an external operation device such as a remote controller to guide the light toward thelight receiving element 35 provided on the printedcircuit board 30. - The
front cover 70 is attached to thetop grille 11 so as to cover thefirst hole 11a of thetop grille 11 and the indicatingpart 51 of theswitch cover 50 disposed in thefirst hole 11a. Thefront cover 70 includes aprotrusion 71 that is translucent and has a circular dome shape, theprotrusion 71 being provided so as to cover the indicatingpart 51 of theswitch cover 50. A light-shielding coating is applied to a part of theprotrusion 71. Accordingly, a light-shieldingpart 72 having a circular shape is formed in the part of theprotrusion 71. Thefront cover 70 according to the present embodiment is an example of a cover according to the present disclosure. -
Fig. 3 is a plan view of a region around the indicatingdevice 20 according to the present embodiment.Fig. 3 illustrates a state where theswitch cover 50 and the front cover 70 (illustrated inFig. 2 ) are removed. - With reference to
Fig. 3 , thepartition wall 42 is provided so as to surround the firstlight emitting element 31. Accordingly, the firstlight emitting element 31 and the secondlight emitting element 32 are separated from each other by thepartition wall 42. In other words, thepartition wall 42 is provided so as to intersect with a virtual line VL connecting a center of the firstlight emitting element 31 and a center of the secondlight emitting element 32. Further, the secondlight emitting element 32 and the thirdlight emitting element 33 are disposed on a side opposite to the firstlight emitting element 31 relative to thepartition wall 42. Note that when the firstlight emitting element 31 is viewed from above, a center of gravity of an upper surface of the firstlight emitting element 31 coincides with a center of the firstlight emitting element 31. Similarly, when the secondlight emitting element 32 is viewed from above, a center of gravity of an upper surface of the secondlight emitting element 32 coincides with a center of the secondlight emitting element 32. - A first distance d1 between the
partition wall 42 and the firstlight emitting element 31 is shorter than a second distance d2 between thepartition wall 42 and the secondlight emitting element 32. Specifically, the first distance d1 is a distance on the virtual line VL between thepartition wall 42 and the firstlight emitting element 31. The second distance d2 is a distance on the virtual line VL between thepartition wall 42 and the secondlight emitting element 32. According to the present embodiment, the second distance d2 is at least twice the first distance d1. The second distance d2 is preferably at least three times the first distance d1. -
Fig. 4 is a plan view of the region around the indicatingdevice 20 according to the present embodiment.Fig. 4 illustrates a state where the front cover 70 (illustrated inFig. 2 ) is removed. That is, inFig. 4 , theswitch cover 50 is exposed. - The indicating
part 51 according to the present embodiment includes afirst region 52 irradiated with the light emitted from the firstlight emitting element 31 and the light emitted from the secondlight emitting element 32, and asecond region 53 irradiated only with the light emitted from the secondlight emitting element 32. InFig. 4 , thefirst region 52 is indicated by dot hatching, and thesecond region 53 is indicated by line hatching. - The
first region 52 is defined by thepartition wall 42. Thepartition wall 42 having a light-shielding property can prevent the light emitted from the firstlight emitting element 31 from spreading to the outside of thefirst region 52 by limiting a region of the indicatingpart 51 irradiated with the light emitted from the firstlight emitting element 31 to thefirst region 52. This makes it possible to clearly distinguish between thefirst region 52 irradiated with the light emitted from the firstlight emitting element 31 and thesecond region 53 not irradiated with the light emitted from the firstlight emitting element 31 in the indicatingpart 51. Further, thefirst region 52 is partially covered with the light-shielding part 72 (indicated by a long dashed double-short dashed line in the drawing) of thefront cover 70. - The indicating
part 51 is entirely irradiated with the light emitted from the secondlight emitting element 32 according to the present embodiment. Similarly, the indicatingpart 51 is roughly entirely irradiated with the light emitted from the thirdlight emitting element 33 according to the present embodiment. Thesecond region 53 according to the present embodiment is a part of the indicatingpart 51 not irradiated with the light emitted from the firstlight emitting element 31. Further, thesecond region 53 is partially covered with the light-shielding part 72 (indicated by a long dashed double-short dashed line in the drawing) of thefront cover 70. - The
first region 52 irradiated with the light emitted from the firstlight emitting element 31 is higher in average illuminance than thefirst region 52 irradiated with the light emitted from the secondlight emitting element 32. - A longest distance L1 between the first
light emitting element 31 and thefirst region 52 is shorter than a shortest distance L2 between the secondlight emitting element 32 and thefirst region 52. The longest distance L1 is a linear distance in a three-dimensional space between a point A farthest from the firstlight emitting element 31 in thefirst region 52 and the first light emitting element 31 (illustrated in a planar view inFig. 4 ). Similarly, the shortest distance L2 is a linear distance in a three-dimensional space between a point B closest to the secondlight emitting element 32 in thefirst region 52 and the second light emitting element 32 (illustrated in a planar view inFig. 4 ). -
Fig. 5 is a cross-sectional view taken along line V-V ofFig. 4 . - With reference to
Fig. 5 , the firstlight emitting element 31, the secondlight emitting element 32, and the thirdlight emitting element 33 are surrounded by thewall 41 of thelamp cover 40. Further, thepartition wall 42 having a light-shielding property is provided between the firstlight emitting element 31 and the secondlight emitting element 32. Further, thepartition wall 42 is disposed at a distance from the indicatingpart 51 of theswitch cover 50. Thepartition wall 42 prevents the light emitted from the firstlight emitting element 31 from widely spreading and defines thefirst region 52 by limiting the region irradiated with the light emitted from the firstlight emitting element 31 in the indicatingpart 51. On the other hand, the light emitted from the secondlight emitting element 32 passes between thepartition wall 42 and the indicatingpart 51 to impinge all over the indicatingpart 51. Thepartition wall 42 is smaller in dimension in a rising direction (vertical direction inFig. 5 ) than thewall 41. The dimension of thepartition wall 42 in the rising direction is at least 1/2 times the dimension of thewall 41 in the rising direction. The dimension of thepartition wall 42 in the rising direction is preferably at least 2/3 times the dimension of thewall 41 in the rising direction. - A surface of the printed
circuit board 30 includes an installation region R defined by thewall 41 of thelamp cover 40. Thepartition wall 42 partitions the installation region R into a first installation region R1 and a second installation region R2. The firstlight emitting element 31 is disposed in the first installation region R1, and the secondlight emitting element 32 is disposed in the second installation region R2. - The
switch cover 50 includes a projectingpart 54 extending from the indicatingpart 51 toward theoperation switch 34. When the indicatingpart 51 is pressed toward the printedcircuit board 30, the projectingpart 54 moves toward the printedcircuit board 30 to press theoperation switch 34 provided on the printedcircuit board 30. That is, theswitch cover 50 according to the present embodiment serves as an operation part that is operated by the user to operate theoperation switch 34. The indicatingpart 51 of theswitch cover 50 according to the present embodiment is an example of an operation part of a switch according to the present disclosure. - The
light receiving lens 60 is partially exposed to the outside from thetop grille 11. Further, thelight receiving lens 60 extends from the part exposed to the outside toward thelight receiving element 35. - The
front cover 70 is disposed so as to cause theprotrusion 71 to face the indicatingpart 51 of theswitch cover 50. Accordingly, the light-shieldingpart 72 formed in theprotrusion 71 is disposed at a position corresponding to the indicatingpart 51 serving as the operation part of the switch according to the present disclosure. Further, theprotrusion 71 protrudes in a direction remote from the indicatingpart 51. This increases visibility of the indicatingpart 51 as viewed from the side. -
Fig. 6 is a diagram illustrating one light emission mode of the indicatingdevice 20 according to the present embodiment. - In one light emission mode illustrated in
Fig. 6 , the first light emitting element 31 (illustrated inFig. 4 ) is off, and the second light emitting element 32 (illustrated inFig. 4 ) or the third light emitting element 33 (illustrated inFig. 4 ) is on. For example, when the air conditioner is in the cooling operating mode, the secondlight emitting element 32 irradiates thefirst region 52 and thesecond region 53 with blue emission light. Further, the indicatingdevice 20 causes, when the air conditioner is in the heating operating mode, the secondlight emitting element 32 to irradiate thefirst region 52 and thesecond region 53 with red emission light. When the air conditioner is in the dehumidifying operating mode, the secondlight emitting element 32 irradiates thefirst region 52 and thesecond region 53 with green emission light. Further, for example, when the air conditioner is in the ventilation operating mode, the thirdlight emitting element 33 irradiates thefirst region 52 and thesecond region 53 with white emission light. The combinations of the operating mode of the air conditioner and the color indicated in thesecond region 53 are not limited to the combinations described above. -
Fig. 7 is a diagram illustrating another light emission mode of the indicatingdevice 20 according to the present embodiment. - In another light emission mode illustrated in
Fig. 7 , the first light emitting element 31 (illustrated inFig. 4 ) is on, and the second light emitting element 32 (illustrated inFig. 4 ) or the third light emitting element 33 (illustrated inFig. 4 ) is on. For example, when a timer is set, the indicatingdevice 20 turns on the firstlight emitting element 31 in addition to the secondlight emitting element 32 or the thirdlight emitting element 33 to indicate that the timer has been set. - For example, when the air conditioner is in the cooling operating mode, the
first region 52 is irradiated with light including green emission light emitted from the firstlight emitting element 31 and blue emission light emitted from the secondlight emitting element 32, and thesecond region 53 is irradiated with the blue emission light emitted from the secondlight emitting element 32. Accordingly, when the air conditioner is in the cooling operating mode, a bluish green color is indicated in thefirst region 52, and a blue color different from the color indicated in thefirst region 52 is indicated in thesecond region 53. - For example, when the air conditioner is in the heating operating mode, the
first region 52 is irradiated with light including green emission light emitted from the firstlight emitting element 31 and red emission light emitted from the secondlight emitting element 32, and thesecond region 53 is irradiated with the red emission light emitted from the secondlight emitting element 32. Accordingly, when the air conditioner is in the cooling operating mode, a reddish green color is indicated in thefirst region 52, and a red color different from the color indicated in thefirst region 52 is indicated in thesecond region 53. - For example, when the air conditioner is in the dehumidifying operating mode, the
first region 52 is irradiated with light including green emission light emitted from the firstlight emitting element 31 and green emission light emitted from the secondlight emitting element 32, and thesecond region 53 is irradiated with the green emission light emitted from the secondlight emitting element 32. At this time, for example, the green color of the light emitted from the firstlight emitting element 31 may be more vivid than the green color of the light emitted from the secondlight emitting element 32. Accordingly, when the air conditioner is in the dehumidifying operating mode, a vivid green color is indicated in thefirst region 52, and a green color different from the green color indicated in thefirst region 52 is indicated in thesecond region 53. - For example, when the air conditioner is in the ventilation operating mode, the
first region 52 is irradiated with light including green emission light emitted from the firstlight emitting element 31 and white emission light emitted from the thirdlight emitting element 33, and thesecond region 53 is irradiated with the white emission light emitted from the thirdlight emitting element 33. Accordingly, when the air conditioner is in the ventilation operating mode, a whitish green color is indicated in thefirst region 52, and a white color different from the color indicated in thefirst region 52 is indicated in thesecond region 53. - The indicating
device 20 according to the present embodiment has the following effects. - The first distance d1 between the first
light emitting element 31 and thepartition wall 42 is shorter than the second distance d2 between the secondlight emitting element 32 and thepartition wall 42. Therefore, a part of the indicatingpart 51 adjacent to the firstlight emitting element 31 relative to thepartition wall 42 is irradiated with the light emitted from the firstlight emitting element 31 and the light emitted from the secondlight emitting element 32 in a superimposed manner. On the other hand, a part of the indicatingpart 51 adjacent to the secondlight emitting element 32 relative to thepartition wall 42 is irradiated only with the light emitted from the secondlight emitting element 32. This makes it possible to increase variations of indication for the indicatingpart 51. - If the
partition wall 42 is in contact with the indicatingpart 51 with no gap between the indicatingpart 51 and thepartition wall 42, a part that is not irradiated with either the light emitted from the firstlight emitting element 31 or the light emitted from the secondlight emitting element 32 appears in a region of the indicatingpart 51 facing thepartition wall 42. The above-described part, therefore, prevents the region irradiated with the light emitted from the firstlight emitting element 31 and the region irradiated with the light emitted from the secondlight emitting element 32 from being continuous with each other. On the other hand, according to the above-described embodiment, the indicatingpart 51 and thepartition wall 42 are arranged at a distance from each other, so that a part of the light emitted from the secondlight emitting element 32 passes between the indicatingpart 51 and thepartition wall 42 to impinge on thefirst region 52. This allows thefirst region 52 and thesecond region 53 of the indicatingpart 51 to be illuminated without interruption. - The longer the distance from the light source, the smaller the light intensity. According to the above-described embodiment, as illustrated in
Fig. 4 , the longest distance L1 between the firstlight emitting element 31 and thefirst region 52 is shorter than the shortest distance L2 between the secondlight emitting element 32 and thefirst region 52. This makes, even in a case where the firstlight emitting element 31 and the secondlight emitting element 32 emit light having approximately the same light emission intensity, light reaching thefirst region 52 from the firstlight emitting element 31 larger in illuminance than light reaching thefirst region 52 from the secondlight emitting element 32. This allows the light emission color of the firstlight emitting element 31 to be clearly indicated in thefirst region 52. - According to the above-described embodiment, the
first region 52 is partially covered with the light-shieldingpart 72 of thefront cover 70, so that thefirst region 52 is partially shielded from light. Accordingly, the part illuminated by the firstlight emitting element 31 and the secondlight emitting element 32 and the part shielded from light by the light-shieldingpart 72 are positioned adjacent to each other in thefirst region 52. This makes the indicated part in thefirst region 52 clear. - According to the above-described embodiment, as illustrated in
Fig. 5 , the light-shieldingpart 72 of thefront cover 70 is disposed at the position corresponding to the indicatingpart 51 serving as the operation part of theoperation switch 34, so that the light-shieldingpart 72 allows the user to clearly recognize the position of the indicatingpart 51. - According to the above-described embodiment, the
first region 52 irradiated with the light emitted from the firstlight emitting element 31 is higher in average illuminance than thefirst region 52 irradiated with the light emitted from the secondlight emitting element 32, so that the light emission color of the firstlight emitting element 31 can be clearly indicated in thefirst region 52. - According to the above-described embodiment, the light emission mode of the indicating
device 20 changes in accordance with the operating mode of the air conditioner, so that the user can easily recognize the operating mode of the air conditioner. Further, for example, changing a light emission pattern or a light emission color as the light emission mode allows an increase in visibility of the indicatingpart 51. - While the embodiment has been described above, it is to be appreciated that various changes in form and detail may be made without departing from the spirit and scope of the claims.
- According to the above-described embodiment, the air conditioner is of a floor-standing type, but the present disclosure is not limited to the embodiment, and the air conditioner may be of another type such as a wall-mounted type, for example.
- According to the above-described embodiment, the air conditioner has four operating modes, the cooling operating mode, the heating operating mode, the ventilation operating mode, and the dehumidifying operating mode, but the present disclosure is not limited to the embodiment, and the air conditioner is only required to have a plurality of operating modes.
