Description

  The present invention relates to a remote control device that controls, for example, a device installed outside a bathroom from inside the bathroom.

  Connected to a hot water supply device provided outside the bathroom via a communication line, wired communication is performed with the hot water supply device via this communication line, and a bath remote control for operating the hot water supply device is fixed to the wall surface in the bathroom Is known.

  In addition, an audio device is installed outside the bathroom, a speaker is provided on the ceiling of the bathroom, and a remote control function for operating the audio device by wireless communication is incorporated in the bath remote control (for example, Patent Document 1). reference).

  In general, it is widely practiced to operate an audio apparatus by, for example, wireless communication using infrared rays emitted from a remote controller. In this case, since the audio device itself can be visually observed, for example, the set value of the volume may be displayed on the audio device instead of the remote controller. However, in the case of a remote controller that operates an air conditioner by wireless communication using infrared rays, such as a remote controller for an air conditioner, the set temperature and the type of operation are often displayed on the remote controller instead of the air conditioner itself.

In this way, when the display unit is provided on the remote control and the operation content performed on the remote control, for example, the set temperature is displayed on the display unit, the display content on the display unit is changed based on the operation performed on the remote control. Is done.
JP 2002-38735 A (claim 4, paragraph 0048, FIG. 7)

  A remote controller that operates a device by wireless communication as described above, and includes a display unit that displays details of operations performed on the remote controller, for example, when operating an audio device installed outside the bathroom When an operation for lowering the volume is performed on the remote controller, the display about the volume displayed on the remote controller changes to a display with the volume lowered according to the operation.

  However, when connected via a communication line and performing wired communication, the signal transmitted from the remote control side reliably reaches the device side, but in the case of wireless communication, disturbances and the signal itself are not received by the device side. For example, a signal emitted from the remote controller does not always reach the device side.

  For example, when an audio device is operated with a remote controller, the volume of the audio device remains high if the signal does not reach the audio device even if the volume is reduced as described above. Even if the volume is displayed on the audio device, the audio device cannot be confirmed from within the bathroom, so the operator in the bathroom believes that the volume has decreased.

  When the power of the audio device is turned on in this state, music is played at a loud volume that is completely different from the volume expected by the operator, resulting in a problem that the operator is surprised.

  In view of the above problems, it is an object of the present invention to provide a remote control device that does not cause the above problems.

  In order to solve the above problems, a remote control device according to the present invention is a remote control device that performs operation of a device by wireless communication, and includes a transmission unit that transmits a wireless signal to the device and a display unit that displays transmission contents. The apparatus includes a receiving unit that receives a radio signal from the device side, and a correction unit that corrects the display content of the display unit based on the received signal.

  The display unit displays the details of the operation performed on the remote control device. By receiving the actual state of the device and correcting the display content on the display unit, the actual state of the device and the display content are displayed. Match.

  For example, the wireless signal is superimposed on infrared rays. Since wireless communication using infrared rays cannot be performed unless infrared rays enter the light receiving unit of the other party, the case where the state of the device does not match the display on the display unit of the remote control device is relatively likely to occur. Therefore, the present invention is particularly suitable for a remote control device that performs wireless communication using infrared rays.

  Specifically, the device is installed in a bathroom, and a device-side receiving unit that receives a radio signal transmitted from the transmitting unit and a device-side transmitting unit that transmits a radio signal from the device side are provided in the bathroom. It may be installed so as to face inside, and the operation of the device may be performed from inside the bathroom.

  As is apparent from the above description, in the case of a remote control device provided with a display unit, the display content of the display unit of the remote control device may be different from the actual state of the device. According to this, since the signal from the device side is received and the display content of the display unit is corrected, the display content of the display unit of the remote control device and the actual device state can be reliably matched.

  Referring to FIG. 1, reference numeral 1 denotes a bathroom, and an audio device 2 is disposed outside the bathroom. The audio signal output from the audio device 2 is supplied to the pair of speakers 21 and 22 via the audio signal line 2a. These speakers 21 and 22 are both attached to the ceiling 11 of the bathroom 1.

  An audio remote controller 3 for operating the audio device 2 is disposed in the bathroom 1. The audio remote controller 3 is a so-called infrared remote controller that emits infrared light on which an operation signal is superimposed. A hot water supply device 4 is installed outside the bathroom 1, and the operation of the hot water supply device 4 is performed by a bath remote controller 5 installed in the bathroom 1. The bath remote controller 5 is also a so-called infrared remote controller that emits infrared light on which an operation signal is superimposed, like the remote controller 3.

  Referring to FIGS. 2 and 3, one speaker 21 has a device-side light receiving unit 61 and a device-side light-emitting unit 62 attached to the inside covered with a mesh 21 a. Reference numeral 63 denotes a light-emitting diode for confirmation that emits light during signal transmission / reception.

  When the device-side light receiving unit 61 receives infrared rays with superimposed signals, it separates the superimposed signals and converts them into electrical signals. The signal converted into the electrical signal is input to the signal input units of the audio device 2 and the hot water supply device 4 through the communication line 6a. On the other hand, the device-side light-emitting unit 62 emits the electrical signal sent from the signal output unit of the audio device 2 and the hot water supply device 4 into the bathroom 1 by superimposing it on infrared rays.

  The remote controller 3 is provided with a communication unit 30 in which a light emitting unit that emits infrared rays from the remote controller 3 and a light receiving unit that receives infrared rays emitted from the device-side light emitting unit 62 are stored. In addition, a display unit 31 is provided for displaying details of operations performed on the remote controller 3.

  For example, when the volume increase / decrease switch 32 is operated, the volume display mark 33 is increased / decreased, and the volume setting state is displayed on the display unit 31. For example, when an operation of lowering the volume is performed, the volume display mark 33 is decreased and infrared rays on which a signal for lowering the volume is superimposed are emitted from the communication unit 30. The emitted infrared light is received by the device-side light receiving unit 61, the signal is separated, and transmitted to the audio device 2 via the communication line 6a. The signal for lowering the volume is also transmitted to the hot water supply device 4. However, if the communication codes of the audio device 2 and the hot water supply device 4 are different, the hot water supply device 4 includes a signal for lowering the volume and is used for the audio device 2. Ignore all signals.

  When the audio device 2 receives the signal for reducing the volume, the audio device 2 internally performs an operation for decreasing the volume. On the other hand, the actual operating state of the audio device 2 is output from the signal output unit to the device-side light emitting unit 62 via the communication line 6b at regular intervals. Then, the apparatus side light emission part 62 inject | emits the infrared rays which superimposed the signal.

  The emitted infrared light is received by the communication unit 30 and separated and decoded in the remote controller 3. Then, the content displayed on the display unit 31 is replaced with the display content corresponding to the actual operating state received from the device-side light emitting unit 62.

  With this configuration, for example, when the operation of lowering the volume is performed with the remote controller 3 as described above, if the infrared light emitted from the remote controller 3 is not received by the device-side light receiving unit 61, the volume of the display unit 31 Even if the display mark 33 decreases, the volume display mark 33 increases so as to match the actual volume according to the signal from the audio device 2 side. Thus, even if the signal from the remote controller 3 does not reach the audio device 2, the actual operating state of the audio device 2 matches the display on the display unit 31.

  Although the case where the audio device 2 is operated using the remote controller 3 has been described in the above embodiment, the present invention is similarly used when the hot water supply device 4 is operated by infrared communication using the bath remote controller 5. Can do.

  In addition, since the code | cord | chord of a signal is made different between the audio apparatus 2 and the hot-water supply apparatus 4 as mentioned above, both signals do not interfere. Therefore, it is possible to add another device with a different signal code and operate from the bathroom 1 in the same manner as described above.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention.
