Description

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

Conventionally, there is a technique of this type that expands the receivable range by changing the mounting angle of the light emitting element mounted in the remote control device.
Japanese Utility Model Publication No. 61-89748

  Generally, a remote control device for an air conditioner has an infrared light emitting element as a signal transmitting element and transmits a signal to the air conditioner. Therefore, the signal may not reach the air conditioner from the operation place or installation place of the remote control device.

  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 correctly transmit a signal to an air conditioner.

In order to solve the above-mentioned conventional problems, the remote control device of the present invention is configured such that a plurality of light-emitting elements that are mounted in advance by changing the angle and direction are operated and set by a switch that can select the light-emitting elements. By selecting the most effective light emitting element according to the place, a remote control device capable of reliably performing transmission / reception between the remote control device and the air conditioner is provided.

  The remote control device for an air conditioner according to the present invention selects an optimal transmission element according to an operation place and an installation place by using a switch for selecting a light emitting element for transmission arranged at different angles and directions. Thus, transmission / reception between the air conditioner and the remote control device can be performed reliably.

  A remote control device for an air conditioner is generally composed of a control IC, a printed circuit board on which peripheral circuits, infrared light emitting elements for transmission and the like are arranged, a display material, a contact sheet, a case, a battery, and the like. ing.

  In the present invention, a plurality of infrared light emitting elements for transmission are arranged at different angles and directions, and a selection switch for switching the validity / invalidity of each individual light emitting element circuit is provided. By selecting the most effective transmitting element, transmission and reception between the air conditioner and the remote control device can be performed reliably.

(Embodiment 1)
FIG. 1 is a circuit diagram of a remote control device according to an embodiment of the present invention, and includes a plurality of transmitting elements and switches for switching the transmitting elements. FIG. 2 is a top view of the remote control device according to the embodiment of the present invention, in which a transmission element whose direction is changed and a selection switch are provided on a printed wiring board. FIG. 3 is a side view of the remote control device according to the embodiment of the present invention.

  In FIG. 1, reference numerals 1a, 1b, and 1c denote transmission elements, and selection switches 2a, 2b, and 2c are provided on the circuit together with a resistor 8 for limiting current, and a transmission signal is output by a transistor 11 controlled by a control IC 7. However, the transmission element 1 of the circuit in which the selection switch 2 is closed outputs a signal, but the transmission element 1 of the circuit in which the selection switch 2 is open does not output.

  In such a configuration, the specific contents of the present invention will be described with reference to FIGS. 2 and 3. First, a plurality of transmitting elements 1 provided on the printed circuit board 9 have a direction and a direction in order to widen the transmission range. Three (1a, 1b, 1c) are arranged at different angles. Similarly, the selection switches 2 for selecting the three transmission elements 1 are also arranged on three (2a, 2b, 2c) printed wiring boards 9 and housed in the remote control device 4.

  When the operator operates the remote control device at hand, the operator operates the remote control device 4 straight to the air conditioner. Therefore, if transmission is performed using only the central transmission element 1b, the transmission is reliable. Therefore, only the selection switch 2b needs to be switched to the ON side. When the operator operates the remote control device 4 while attached to the wall, the air conditioner and the remote control device 4 are used. Therefore, when the air conditioner is attached to the right side with respect to the remote control device 4, it is only necessary to use the transmission element 1c. Therefore, the selection switch 2a may be switched to the ON side. If it is mounted on the left side, the selection switch 2c may be switched to the ON side in order to use the transmission element 1a. Since the selection switch 2 can be switched according to the operation place of the remote control device 4 in this way, transmission / reception with the air conditioner can be performed reliably.

  Further, by making the transmission element 1 selectable, it is only necessary to switch the selection switch of the unnecessary transmission element 1 to the OFF side, so that the consumption of the battery 6 in the remote control device 4 can be suppressed, which is economical. It is.

  As described above, the remote control device for an air conditioner according to the present invention can be remotely connected to an air conditioner regardless of the operation location by switching a plurality of transmission elements whose directions and angles are changed and a switch for selecting the transmission element. It is possible to realize the reliable transmission and reception of the operating device.
