  In the present invention, two states related to air conditioning can be individually displayed by two light emitting display units, and more information about the state related to air conditioning can be transmitted to the user.

  Hereinafter, the present invention will be described based on an embodiment shown in the accompanying drawings. FIG. 2 and FIG. The air conditioner 1 in the illustrated example that can be installed on the wall is a horizontally long and thin front and rear body with a built-in blower fan, and the airframe 10 has an air inlet at its lower end surface. 11, the exhaust port 12 is provided at the upper end surface, the second intake port 21 is provided at the portion near the lower end of the front surface, and the second exhaust port 22 is provided at the portion near the upper end of the front surface of the fuselage. 2 The air inlet 21 and the second air outlet 22 can be opened and closed by the flaps 4 respectively. As shown in FIG. 5, the flap 4 that opens and closes by pivoting on the side opposite to the end face of the machine body 1 is connected to a crank 45 that is rotationally driven by a flap motor M <b> 2 (see FIG. 4) with a connecting rod 46. Connected and rotated about the hinge 40 by the rotation of the motor M2. The reason why the fulcrum of the flap 4 is arranged at the above position is to make intake and exhaust more smooth.

  The first light emitting display unit 31 is disposed between the air inlet 11 and the second air inlet 21 disposed adjacent to the air inlet 11 and is located at the lower front end of the airframe 10, and the second light emitting display unit 32. Is disposed between the exhaust port 12 and the second exhaust port 22 disposed at a position adjacent thereto, and is positioned at the upper front end of the body 1. Further, the light emitting display portions 31 and 32 have a width over the entire width of the machine body 10.

  Here, the light emitting display portions 31 and 32 are each composed of a large number of three-color LEDs 3a arranged in a line in the machine body 10 and a light guide plate 3b arranged on the front surface of the machine body 1 so as to cover the entire width. Light enters from the end face and exits from the other surface, so that the light guide plate 3b emits light as if it were emitting light, and can function not only as a light emitting display but also as illumination. In particular, since the LED 3a is composed of three colors, the color of the light guide plate 3b that can shine can be changed to any color, and one end side and the other end side of the light guide plate 3b. It is also possible to emit different colors. Further, since the front end side of the flap 4 is in a position covering a part of the light emitting display portions 31 and 32, when the light emitting display portions 31 and 32 shine, a part of the front end surface and the back surface of the flap 4 is the light emitting display portion 31. , 32 and receiving the light from the light, the color is changed. Therefore, even when the flap 4 is opened and closed, a varying illumination can be obtained.

  The surface of the light guide plate 3b of the first light emitting display unit 31 and each surface of the light guide plate 3b of the second light emitting display unit 32 are flush with the second air inlet 21 and the second air outlet 22, respectively. This is because dirt and dust are less likely to accumulate.

  In the air conditioner 1 formed as an air purifier, the flaps 4 and 4 close the second intake port 21 and the second exhaust port 22, and if the built-in air blowing means is operated, the intake port 11 and the second intake port 21 are filtered and cleaned by a filter or the like and then discharged from the exhaust port 12 or the second exhaust port 22. When the air volume is set, the flap 4 is held in a state in which the second air inlet 21 and the second air outlet 22 are closed or slightly opened. When the air volume is set to a large value, the flap 4 holds the second intake port 21 and the second exhaust port 22 in a wide open state, or in the half-open state shown in FIG. 5 (b) and FIG. 5 (c). The movement which repeats the fully open state shown is performed.

  FIG. 4 shows a block circuit diagram of the air cleaner 1. The control circuit 5 is connected to the dirt sensors 52 and 52 for detecting the dirt of the air and drives the blower fan motor M1 and the flap motor M2 in the blower means via the motor drive circuits 53 and 54, respectively. The LEDs 3 a and 3 a in the two light emitting display units 31 and 32 are connected via LED driving circuits 55 and 55, and the light emitting display units 31 and 32 perform light emission and color change under the control of the control circuit 5. Further, the control circuit 5 changes the amount of air blown by the air blowing means and opens / closes the flap 4 in accordance with the degree of air dirt detected by the dirt sensors 52, 52.

  Next, an example of how the light emission display units 31 and 32 emit light will be described. When the two dirt sensors 52 and 52 are provided in the intake passage and the exhaust passage, respectively, intake is performed. The color of the light-emitting display unit 31 can be changed according to the degree of air contamination, and the color of the light-emitting display unit 32 can be changed according to the degree of air exhausted. It is possible to indicate to the user how much the degree of air contamination has been suppressed by passing through the air conditioner 1. Further, as the air purification progresses, the color of the light-emitting display unit 31 and the color of the light-emitting display unit 32 also change, and if both eventually become the same color, the air is no longer contaminated (dirt sensor 52). This means that the user can no longer get dirt that can be detected.

  Here, the fact that the light emission display unit 31 is located in the vicinity of the intake port 11 and the second air intake port 21 and the light emission display unit 32 is located in the vicinity of the exhaust port 12 and the second exhaust port 22 indicates that the light emission display unit 31 is Thus, the user can easily understand that the state of the air that is taken in indicates the state of the air that the light emitting display unit 32 exhausts.

  When the air conditioner 1 has a temperature adjustment function and a humidity adjustment function, the operation of the light emitting display unit 31 is changed according to the temperature or humidity detected from the intake side, and the temperature or humidity of the exhausted air is changed. The operation of the light-emitting display unit 32 may be changed according to the color of the light-emitting display units 31 and 32. Further, the color of the light-emitting display units 31 and 32 indicates the state of the combination of the degree of air contamination, temperature and humidity. You may make it display.

  The first light-emitting display unit 31 emits light in a color corresponding to at least one of the degree of contamination of air to be sucked, temperature, and humidity, and the second light-emitting display unit 32 is set by the user. You may make it light-emit in the color according to the target value regarding the degree of dirt of air, temperature, or humidity. In this case, if the color of the 1st light emission display part 31 becomes the same as the color of the 2nd light emission part 32, the user can recognize that it became the set target value at a glance.

  In addition, the color of the light-emitting display unit 31 is adjusted according to at least one of the degree of contamination of air to be sucked, temperature, and humidity, so that the blowing state such as the blowing amount of the blowing means and the opening / closing degree of the flap 4 is obtained. Accordingly, the color of the light emitting display unit 32 may be adjusted. The user can determine at a glance the air state and the operating state.

  In addition, you may make it the light emission display part 31 and the light emission display part 32 perform the same operation | movement according to the condition of the air (indoor air) by the side of intake.

  In addition to this, what is shown is to notify the user of the state by adjusting the color of the light emitting display portions 31 and 32. The light emitting display portions 31 and 32 used here are: Different colors can be mixed in the entire width, or the color can be changed continuously from one end to the other, so the degree of air pollution is indicated by the color, and the air volume is indicated by the color change speed. It is also possible. You may make it display an operation state not with a color but with a blinking speed, the moving speed of a lighting location, etc.

  Moreover, since it has two light emission display parts 31 and 32 of the width over the full width of the airframe 1, and the color of these light emission display parts 31 and 32 can be changed, this can be utilized for interior illumination. May be provided. That is, in addition to the operation state display mode in which the operation of the light emitting display units 31 and 32 is changed according to the state related to air conditioning, the interior in which the operation of the light emitting display units 31 and 32 is changed in a state unrelated to air conditioning. If the interior illumination mode is selected, the light emitting display units 31 and 32 emit light whose color gradually changes regardless of the air state or the operation state of the air blowing means. It is.

  As shown in the illustrated example, it is preferable that the light-emitting display portions 31 and 32 extend over the entire width of the airframe 10 in order to obtain a function as accent lighting. However, when the airframe 1 is vertically long, You may provide as a vertically long thing.

It is sectional drawing of an example of embodiment of this invention. It is a perspective view same as the above. It is a perspective view of the state which opened the flap same as the above. It is a block circuit diagram same as the above. The flap opening / closing mechanism is shown, and (a), (b) and (c) are schematic side views, respectively.
