Further, a plate-like front panel 2 a covering the front surface of the indoor unit body 2 is provided on the front surface of the indoor unit body 2 on the suction port side. A front lower suction port 3a constituting a part of the suction port 3 is formed below the front panel 2a.

  Furthermore, a partition plate 9 is formed in the width direction of the front surface of the indoor unit body 2 to partition the front lower suction port 3a and the blower outlet 4.

  A filter 10 is interposed between the heat exchanger 6 and the suction port 3.

  Also, a ventilation path wall 11 is provided that is inclined obliquely upward and rearward from the upper end edge of the partition plate 9 toward the inside of the front lower suction port 3a and extends to a position slightly lower than the lower end of the front panel 2a. A belt-like member 12 made of a light transmissive translucent material is provided at the upper end portion of the ventilation path wall 11 at a height substantially equal to the lower end of the front panel 2a and installed in the width direction.

  This belt-like member 12 is made of a translucent synthetic resin, has an elongated shape having a width substantially the same as the width of the front lower suction port 3a, and is fixed at a predetermined position in the left-right direction so that it can be fixed to the upper part of the partition plate 9. A locking piece (not shown) is formed.

  The belt-like member 12 is provided with an operation state display portion 13 including a plurality of light-emitting display portions provided integrally with the belt-like member 12. In order to indicate the operation state, a plurality of the operation state display units 13 are arranged in the central portion of the belt-like member 12 at a predetermined interval in the lateral direction, and light emission display is performed by the prism-like optical system member made of a translucent material and the light emitting diode 16. Configure to The light emitting diode 16 uses colors such as transparent, yellow, green, red, and blue, and displays the operation state at that time by changing the lighting position and color according to each operation mode and function. It is like that.

  Further, a switch mechanism portion 17 is provided on the bottom surface of the indoor unit main body.

  As shown in FIGS. 4 to 6, the switch mechanism unit 17 is accommodated in the indoor unit main body 2 so as to face the rectangular opening 18 provided on the bottom surface of the indoor unit main body and from the remote controller. A light receiving element 19 that receives a control signal, a pressing switch 20 that is provided in the vicinity of the light receiving element 19 and that is an emergency operation switch that forcibly operates the air conditioner, and a light-transmitting material that closes the opening 18 and presses it. As a result, the pressing switch 20 is operated via the pressing force transmitting member 21, and the switch operating body 22 also serving as an opening cover is provided.

  The light receiving element 19 and the switch operating body 22 are mounted on the same small mounting board 23, housed in a mounting box 24, and mounted in the indoor unit body 2.

The switch operating body 22 has a rectangular shape in plan view, is substantially flat, and is pivotally supported on the indoor unit body 2 by a fulcrum end 22a located at the end of the opening 18 on the side opposite to the pressing type switch so as to function as a lever. The opening 18 is closed so as to be loosely fitted in the opening 18, and is pressed by the user and has a relatively large area as a power point, and the pressing force transmitted constantly biased downward by the spring 25. A switch pressing portion 22 c is provided as an action point for pressing the member 21 and operating the pressing switch 20 via the pressing force transmitting member 21. The switch pressing portion 22c is provided so as to protrude slightly from the pressing surface 22b, and is loosely fitted into the opening 18 to block the opening 18 by using the protrusion. Since the pressing surface 22b transmits a signal from the remote controller and transmits the signal to the light receiving element 19, the area of the pressing surface 22b is set large so that the signal can be transmitted even when the operation position of the remote controller is relatively wide. For this reason, also as a function of the switch pressing surface 22b, it can be operated on a wide surface, and has two merits of improving operability.

  Since the indoor unit body of the air conditioner according to the present embodiment is provided with the switch mechanism 17 as described above, the light emitted from the remote controller is reliably operated as an opening cover during normal use. The light passes through the pressing surface 22 b of the body 22, is received by the light receiving element 19, and inputs a desired operation state (mode) to the indoor unit 2.

  On the other hand, when it is desired to operate the air conditioner but the remote control cannot be performed due to a battery failure of the remote control or the like, the pressing switch 20 is pressed by pressing the pressing surface 22b of the switch operating body 22 which also serves as an opening cover. The air conditioner can be operated by turning it on.

  Thus, since the switch operating body 22 has a relatively large rectangular pressing surface 22b that closes the opening 18, the position of the pressing switch 20 can be easily confirmed, and the difficulty of pressing is eliminated. Thus, the operability can be improved and light from the remote controller can be reliably transmitted to the light receiving element 19 through the pressing surface 22b. Furthermore, since it is separated from the display unit such as a light emitting element provided on the front surface of the indoor unit main body, the display function and the operation function can be clearly distinguished. Moreover, since the switch mechanism part 17 can be made into the substantially same plane as the indoor unit main body 2, functionality and design can be improved.

  In FIG. 6, an electrical component box 26 that houses a control board on which electrical components of the indoor unit are mounted is disposed on one side of the indoor unit body 2 where the switch mechanism 17 is disposed. It is connected to the mounting substrate 23 of the mechanism part 17 by electric wiring.

  As described above, according to the indoor unit of the air conditioner of the present embodiment, the emergency operation switch can be easily pushed, the position of the emergency operation switch can be easily confirmed, and the cost can be reduced. An air conditioner indoor unit that can be made is realized.
