JP 58-198634 A

  However, in the indoor unit of an air conditioner proposed in Patent Document 1, a switch that is used only during assembly or service is provided in a state of being exposed to the main body, so that the design is inferior. There was a point, and it was necessary to make sure that the design was not impaired, which was a problem to be solved.

  In order to solve the above-described problems of the prior art, the present invention receives a signal transmitted from a wireless remote controller to a main body portion provided with a heat exchanger, a blower, and a control means and sends the signal to the control means, and receives a pressing force. In the indoor unit of an air conditioner provided with a mechanical switch that operates and transmits a signal for use to the control means, the receiving means and the mechanical switch are arranged in parallel, and a wireless remote controller is provided in front of the receiving means and the mechanical switch. The main feature is that a switch covering member for operating the mechanical switch with the back side in contact with the mechanical switch at the time of immersion is provided so as to be retractable.

  According to the present invention, an operation instruction such as a cooling operation and a heating operation transmitted from the wireless remote controller is provided behind the switch covering member that is made of a material that can transmit a transmission signal from the wireless remote controller and can be moved in and out. Since the receiving means for receiving the signal and the mechanical switch that is pressed and operated when performing a trial run or the like are provided adjacent to each other, the design property is not impaired, and the switch covering member is an operation button of the mechanical switch. Since it also serves as a protective cover for the receiving means, the configuration can be simplified.

  Receiving means for receiving operation instruction signals such as cooling operation and heating operation transmitted from the wireless remote control behind the switch covering member that is made of a material that can transmit the transmission signal from the wireless remote control and is capable of appearing and retracting, An air conditioner provided with an adjacent mechanical switch capable of directly instructing operations such as cooling operation and heating operation by pressing operation, and further provided with an operation state display means for displaying an operation state by a difference in lighting state Indoor unit.

  An embodiment of the present invention will be described with reference to FIGS. In order to facilitate understanding, in these drawings, parts having the same functions as those described with reference to FIG.

  The indoor unit 100 of the present invention uses air that has been temperature-adjusted by heat-exchanging air taken into the machine by a blower (not shown) from the air intake port 2 of the main body 1 and refrigerant flowing inside a heat exchanger (not shown). The air is blown out from the air outlet 3 and used for adjusting the temperature in the room.

  In the indoor unit 100 of the present invention, a communication port 4 is opened on the front surface of the main body 1 made of a non-translucent synthetic resin, and the communication port 4 is sealed by a removable lid member 5. A light receiving element 7 provided on the substrate 6, a mechanical switch 8, and an operation state display means 9 are installed facing the communication port 4.

  The light receiving element 7 receives a signal transmitted by, for example, infrared rays from the wireless remote controller 50 in order to perform cooling operation, heating operation, timer operation, etc. in cooperation with an outdoor unit (not shown). Transmission is provided to a control means (not shown) provided in the main body 1.

  On the other hand, the mechanical switch 8 performs cooling operation, cooling operation, heating operation, dehumidification operation, etc. in cooperation with an outdoor unit (not shown) if the number of times of pressing within a predetermined time, for example, 5 seconds, is 1, A signal for instructing a heating operation at the time of rotation and a dehumidification operation at the time of rotation is provided so as to be transmitted to a control means (not shown) provided in the main body 1.

  The operation state display means 9 is composed of a green diode 9A, a green diode 9B, and a red diode 9C, and a control means (not shown) receives a signal for instructing a cooling operation or a heating operation from the light receiving element 7 or the mechanical switch 8. For example, when the uppermost green diode 9A is energized to emit green light, and when a signal instructing the dehumidifying operation is received, the lowermost red diode 9C is energized to emit red light, and the light receiving element 7 When a signal instructing timer operation is received from the wireless remote controller 50, the remaining green diode 9B in the center is energized to emit green light.

  The lid member 5 is made of a non-translucent synthetic resin and has a main body portion. The lid member 5 is detachably engaged with the main body portion 1 that surrounds the communication port 4 by a locking claw 10 provided at the peripheral edge portion. 4 is sealed.

  The lid member 5 is provided with a receiving port 11 at a site facing the light receiving element 7 of the substrate 6 and a transmitting port 12 at a site facing the operation state display means 9, and is thermally deformed on the inner surface of the main body on the transmitting port 12 side. The receiving port 11 and the transmitting port 12 are sealed by a lining member 14 made of a translucent milky white resin that is fixed by the welded portion 13 and that can transmit infrared rays or the like.

  Therefore, the signal transmitted from the wireless remote controller 50 by infrared rays passes through the lining member 14 at the part facing the receiving port 11 and reaches the light receiving element 7 of the substrate 6, and the light emitted from the operation state display means 9 of the substrate 6 is Although it passes through the lining member 14 at the part facing the transmission port 12 and goes out of the machine, the lining member 14 is made of a translucent milky white resin. I can't see it.

  The lid member 5 is provided with a switch covering member 16. The switch covering member 16 is formed such that a portion of the lining member 14 facing the receiving port 11 protrudes forward. Further, the switch covering member 16 is folded back from the terminal end side of the two arm members 15 extending from the heat deformation welded portion 13 side of the lid member 5 to the receiving port 11 side to the heat deformable welded portion 13 side. A switch pressing portion 17 is provided on the tip side, that is, on the back surface of the heat deformation welded portion 13 side.

  Therefore, when the switch covering member 16 of the lid member 5 is pressed from the front side, the two arm members 15 themselves and the connecting portion between the arm member 15 and the switch covering member 16 are elastically deformed and bent toward the substrate 6 side. Mu At that time, the switch pressing portion 17 is in contact with the mechanical switch 8 so that the mechanical switch 8 is pressed.

  That is, in the indoor unit 100 of the present invention, it is possible to instruct the air conditioner to perform a desired operation by pressing the switch covering member 16, and the operation state at that time is the light emission of the operation state display means 9. Can be identified by color.

  Therefore, not only during the trial operation when assembling the air conditioner, but also when the wireless remote controller 50 breaks down, the desired cooling operation or heating operation can be provided. In addition, since the mechanical switch 8 that is rarely used, such as during trial operation or when the wireless remote controller 50 is broken, is hidden by the milky white lining member 14, it does not become obstructive.

  In addition, since this invention is not limited to the said embodiment, various deformation | transformation implementation is possible in the range which does not deviate from the meaning as described in a claim.

  For example, transmission / reception of control signals performed between the wireless remote controller 50 and the light receiving element 7 may be performed via radio waves.

  Moreover, the color of the lining member 14 may be other than milky white. That is, the lining member 14 can transmit the light emitted from the operation state display means 9 when the signal transmitted from the wireless remote controller 50 reaches the light receiving element 7, and the light receiving element 7, the mechanical switch 8, and the operation state display. As long as the means 9 is not visible from the outside of the apparatus, any color may be used as long as it is translucent with an appropriate color that matches the colors of the main body 1 and the lid member 5.

  The operation state display means 9 is composed of a blue diode, a green diode, and a red diode. When a control means (not shown) receives a signal for instructing cooling operation from the light receiving element 7 or the mechanical switch 8, for example, blue When a signal to instruct the heating operation is received by energizing the diode to emit cold blue light, for example, when a signal to instruct the dehumidifying operation by energizing the red diode to emit warm red light is received. When a signal indicating the timer operation is received by energizing the remaining green diodes and emitting a cold green color, for example, energizing the blue diodes and the green diodes to produce the cold blue and green colors. It is also possible to configure to emit light at the same time.
