Abstract

<P>PROBLEM TO BE SOLVED: To provide a remote controller capable of transmitting a signal to an air conditioner body regardless of an operation place or an installation place, in regard to a remote controller carrying out remote control of an air conditioner by an infrared element for transmission. <P>SOLUTION: By providing a reflector 5 in front of the infrared element 1 for transmission in the remote controller, providing a structure allowing adjustment of the angle of the reflector 5, and adjusting a transmission direction in an operation place or an installation place of the remote controller 10, transmission can be carried out in a wide range with respect to the air conditioner body. By this, operation from a wider range, and installation in a wider range of the remote controller can be carried out. By using a polyhedron as the reflector, the range can be widened further. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a remote control device for an air conditioner using an infrared light emitting element.

Conventionally, as shown in FIG. 5, this type of technology attaches at least two transmission infrared elements 1 at different angles in a remote control device, and attaches a translucent plate 2 to a case facing each element. Some are installed to widen the reception range (see, for example, Patent Document 1).
Japanese Utility Model Publication No. 61-89748

  However, the above-described conventional configuration is uneconomical because at least two or more transmission infrared elements are required, and a remote control device can be used where a signal from the plurality of transmission infrared elements cannot reach. It was inconvenient because there was no way to deal with it.

  The present invention solves the above-described conventional problems, and an object of the present invention is to provide a remote control device that can transmit a signal to an air-conditioning main body regardless of an operation place or an installation place.

  In order to solve the above-mentioned conventional problems, the remote control device of the present invention is provided with an infrared element for transmission and a reflecting plate in front of the transmitting infrared device, and has a structure in which the angle of the reflecting plate can be moved. The transmission direction can be adjusted at the installation location, and infrared signals can be transmitted over a wide range regardless of the operation location and the installation location.

  The remote control device of the present invention includes a reflector plate in front of the transmission element, and by making the angle of the reflector plate movable, the transmission direction of the infrared signal for transmission is determined by the operation location and installation of the remote control device. Since it is possible to adjust at a place, the air conditioner can be remotely operated in a wider range than before, and the convenience for the user can be improved.

  In the first invention, a reflector is provided in front of the transmission element, and the angle of the reflector is movable, so that the transmission direction of the infrared signal for transmission depends on the operation place and installation place of the remote control device. Since it can be adjusted, it is possible to transmit a signal to the air conditioner body in a wide range.

  In the second invention, the transmission direction of the infrared signal for transmission can be adjusted in a wider range by making the reflection plate a polyhedron.

(Embodiment 1)
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a side view showing the structure of the remote control device according to the first embodiment of the present invention, and FIG. 2 is a top view showing the structure of the remote control device according to the first embodiment of the present invention. It is sectional drawing.

In FIG. 1, a remote control device 14 includes a printed circuit board 7 and a liquid crystal display material 4 stored in an upper case 3 and a lower case 6. On the printed circuit board 7, an electronic component 8 such as a microcomputer and a transmission The trusted infrared element 1 is provided, and the infrared signal output from the transmitting infrared element 1 passes through the light transmitting plate 2 and is transmitted to the receiving element of the air conditioner 13. A reflection plate 5 is disposed in a part of the upper case 3 and is disposed at a position that reflects at least a part of the signal output from the transmission infrared element 1. As a result, the signal output from the transmitting infrared element 1 is divided into a signal transmitted linearly from the element and a signal reflected on the reflecting plate 5 and transmitted in an oblique direction.

  The reflector 5 is fixed to the upper case 3 by a support bar 11 and is connected to an angle adjustment knob 10 via a connection bar 9. The support bar 11 is used as a fulcrum by operating the angle adjustment knob 10. Since the angle of the reflecting plate 5 can be changed by the inclination of the guide 12 provided in the lower case, as shown in FIG. 4, the installation location of the remote control device 14 is installed beside the doorway with respect to the air conditioner 13. In some cases, it is possible to adjust the transmission direction so as to ensure transmission.

(Embodiment 2)
FIG. 3 is a cross-sectional view of the reflection plate 5 of the first invention according to the second embodiment of the present invention as seen from the top, showing a polyhedron. Like the first embodiment, the infrared transmission element 1 is shown in FIG. By making the reflecting plate 5 that reflects the output signal into a polyhedron, the direction of the signal can be adjusted in a wider range than in the first embodiment.

  As described above, the remote control device of the present invention can adjust the infrared signal at the operation place and installation place of the remote control device, so that the air conditioner can be operated from a wider range than before. In addition, it is possible to provide a remote control device that enables transmission even from a location attached to a wide range of positions.
