Description

  The present invention relates to an air conditioner, and more particularly to an air conditioner such as a ceiling embedded type or a ceiling suspended type that is remotely operated by a wireless remote controller.

  Conventionally, this type of air conditioner such as a ceiling-embedded type or a ceiling-suspended type has been provided with a control device for its operation, and in particular, a method for receiving a signal from a wireless remote controller and controlling the operation Is well known.

  The control setting method of the control device of the air conditioner includes a method using a wired remote control installed on the wall and a method using a wireless remote control. Which method is selected depends on the air conditioner. It is determined according to the installation environment and customer requirements, and these works are performed when the air conditioner is installed.

  Hereinafter, an air conditioner remotely operated by a conventional wireless remote controller will be described with reference to FIGS.

  FIG. 4 is a front view of a decorative panel viewed from the indoor side of a conventional ceiling-embedded air conditioner. In FIG. 4, 50 is a decorative panel body of an air conditioner fixed to the ceiling surface, 51 is a suction grill fitted into the central opening on the surface of the decorative panel main body 50, and the decorative panel 52 from the decorative panel main body 50 and the suction grill 51. Is configured. Reference numeral 53 denotes an elongated air outlet provided in the decorative panel main body 50 so as to face each side of the suction grill 51, and is provided at four locations. Reference numeral 54 denotes a suction port provided in the suction grill 51 for taking indoor air into the air conditioner.

  FIG. 5 is an exploded perspective view showing a configuration of the air conditioner body. 57 is an air conditioner body, 56 is a light receiving window for receiving an optical signal from the wireless remote controller 58, 55a is composed of the light receiving window 56 and a light emitting element 55c, and an optical signal received by the light receiving window 56 is It is a light-receiving part for transmitting to a control board (not shown) in order to perform control setting of a control device (not shown).

  The light receiving portion 55a is fitted into and attached to a fitting notch 59 provided on a suction grille 51 that is fitted into the decorative panel body 50. In some cases, the decorative panel body 50 is similarly provided with a notch 59, and the light receiving portion 55b is attached thereto.

  As described above, the light receiving portion 55a or 55b is attached through the suction grille 51 or the cutout portion 59 provided in the decorative panel body 50, and is exposed to the room.

  Thus, the indoor air conditioner operator can arbitrarily change the setting of the control device by pointing the wireless remote controller 58 toward the light receiving window 56 of the light receiving unit 55a or 555b and performing a button operation.

In general, the decorative panel 52 has a complicated structure and requires various types according to various device shapes. Therefore, it is necessary to reduce the manufacturing cost. Further, the decorative panel main body 50 or the suction grille 51 is manufactured by performing notch processing for fitting the light receiving portions 55a and 55b. When the wired remote controller is used, it is not necessary to attach the light receiving portion 55a or 55b, so that a treatment such as inserting another member (not shown) into the notch 59 is performed ( For example, see Patent Document 1).
JP 2003-176929 A

  However, in the conventional configuration, in order to use the wired remote controller, if a separate member is fitted into the notch 59, the design is impaired, and the suction port of the suction portion is reduced, so that the wind circuit design specifications are made appropriate. Need arises. In addition, when the configuration is such that another member can be attached, if the position of the light receiving portion 55a or 55b differs depending on the model, the suction grill or the suction grill body in which the position of the notch 59 for attaching the light receiving portion 55a or 55b is different Since multiple parts are required, there is a problem in that parts are not shared, and a large investment in molds is required to manufacture a different specification, resulting in extra costs. In addition, there is a problem that even if a separate member is not attached and the knockout hole type is used, the design is further impaired. Moreover, the process which provided the notch part 59 in the decorative panel main body 50 which has a complicated shape, or fitted another member had the subject that cost increased excessively.

  The present invention solves the above-mentioned conventional problems, and the light receiving part that receives a signal from the wireless remote controller does not impair the design, does not adversely affect the wind circuit, and manufactures a suction grill and a decorative panel with different specifications. It aims at providing the air conditioner which can be manufactured cheaply without doing.

  In order to solve the conventional problems, an air conditioner according to the present invention includes a heat exchanger, a blower, and a control device that are installed on a ceiling, and an air conditioner that is attached to a lower portion of the air conditioner. A decorative panel body having a suction port and a blowout opening, a light receiving unit that receives a control signal for performing control settings of the control device, and a cover that is detachably attached to the outer periphery of the decorative panel body, The light receiving part is arranged on the cover, and it is only necessary to change the cover between the models that require the light receiving part and the models that do not need it. There is no need to manufacture, and it can be easily used at low cost. Further, since the light receiving portion is provided on the cover attached to the outer periphery of the decorative panel body, the best wind circuit design can be performed without causing any harmful effects on the suction wind circuit.

  In the air conditioner of the present invention, the light receiving part is installed on the cover provided on the outer periphery of the decorative panel body, so that the design of the decorative panel body is not impaired, the suction side of the wind circuit is not affected, and the stable air volume is obtained. Can be set, and the decorative panel body and the suction grille attached thereto can be shared, and can be manufactured at low cost.

  A first aspect of the present invention is a decorative panel body having a heat exchanger, a blower, and a control device with a built-in air conditioner body attached to a ceiling, and an air inlet and a blower outlet attached to a lower portion of the air conditioner body. And a light receiving portion that receives a control signal for performing control settings of the control device, and a cover that is detachably attached to the outer periphery of the decorative panel body, and the light receiving portion is disposed on the cover, For models that require a light receiving unit and models that do not need it, you only need to change the cover, and it is easy to use without compromising the design or producing a separate suction grille or decorative panel. It can be manufactured inexpensively. Further, since the light receiving portion is provided on the cover attached to the outer periphery of the decorative panel body, the best wind circuit design can be performed without causing any harmful effects on the suction wind circuit.

  In the second invention, in particular, the light receiving portion of the first invention is arranged on the back surface of the cover, and it is not necessary to make a cover as a separate part for models that require the light receiving portion and those that do not. Parts can be shared.

  In particular, the third invention includes a cover that is attached to the outer periphery of a plurality of corners of the decorative panel body of the first or second invention, so that each of the covers can be attached to any of the corners and receive light. If the remote control that transmits a signal to the light receiving unit is directional, the cover with the light receiving unit disposed on the side closest to the remote control or at the position where the reception state is the best is provided. -Can be easily attached, and remote control by a remote control or the like can be reliably performed without malfunction.
