Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device for an air conditioner in communication between devices distributed when air conditioning a building or the like.

[0002]

2. Description of the Related Art In recent years, when a building or the like is air-conditioned, there is a blower which can be linked to an air conditioner in order to improve the comfort due to a partial load in the room and individual differences in habitability, and a variable operating state. There is a demand for this, and therefore, it is required to remotely control a plurality of blowers from an air conditioner controller.

Conventionally, a remote control device for an air conditioner of this type is generally shown in FIG. The configuration will be described below with reference to FIG.

As shown in the figure, the signal line 10 is connected from the setting device 109 for controlling the air conditioner 101 and the controller 102.
3 includes a branch box 104 for relaying and connecting signals to a plurality of blower devices 107, and the branch box 104 is configured by a widening device 105 for increasing signal attenuation and a connecting device 106 for the blower devices 107. . Separately from this, the blower device 10 is connected to the power line 109 via the outlet 108.
It supplies electricity to 7.

In the above structure, the controller 102 controls the operation of the plurality of blowers 107 via the branch box 104 by the air conditioner 101 and the special signal line 103.

[0006]

In such a conventional remote control device for an air conditioner, since a special signal is used for remote control, the signal line 103 is required. Therefore, the signal amplification and the blower device 107 are signaled. There is a problem that it takes time and effort when the blower device 107 is moved because the connector 106 for transmitting the information is required. When confirming the operation operation of the blower device 107 via the controller 102 according to a command from the setting device 109, there is a problem that it is difficult to confirm because the controller 102 is in a separate room apart from the blower device 107.

SUMMARY OF THE INVENTION The first object of the present invention is to solve the above problems, and it is a first object of the present invention to remotely control a plurality of blower devices without using a communication line for a special signal.

A second object is to make it easy and easy to confirm the operation and the like of the blower device from the controller 102 side.

A third object is to make it clear that any one of the air blowers in the same system is operating.

[0010]

A first means for achieving the first object of the present invention is to provide a plurality of blower devices capable of communicating with each other, an air conditioner controller for controlling the blower devices, and the same. And a communication means for supplying electric power to the blower device by means of the power line.

Further, the second means for achieving the second object has a constitution in which a terminal setting device for issuing an operation command is provided on the electric power line by being connected to an air conditioner controller capable of communicating with each other. Is.

A third means for achieving the third object is a plurality of air blowers controllable by an air conditioner controller, and even one of the plurality of air blowers operates. In this case, the configuration is such that a specific blower device reports the operating status.

[0013]

According to the present invention, since the electric power line for supplying electric power transmits the remote control signal by the constitution of the above-mentioned first means, it can be remotely controlled without a dedicated communication line.

Further, the setting device has the configuration of the second means,
Since it can be controlled by connecting to an outlet for supplying power to the blower device, it can be set near the blower device and the operation of the blower device can be easily confirmed.

Further, since the operating condition is transmitted from the blower device side to the controller by the configuration of the third means, the operating condition can be easily confirmed on the controller side.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIG.

As shown in the figure, a controller is connected to the air conditioner 1, the blower device 4 is connected to the power supply power line 5, and the controller is connected via the interface 3 (a signal is superimposed on the power line). It is connected to 2.

In the above-mentioned structure, the controller 2 controls the air conditioner 1, while the interface 3 is used to provide the communication signal voltage of a sufficiently higher frequency on the power line 5 for supplying power to the blower device 4. Can be overlapped with each other to communicate with the blower device 4.

As described above, according to the remote control device for an air conditioner of the first embodiment of the present invention, since the controller 2 and the blower device 4 can communicate with each other without using a special signal line, The auxiliary equipment such as the branch box shown in the conventional example is not required, and it is possible to eliminate the labor at the time of construction and to replace the communication wiring even when the blower 4 is relocated.

Next, a second embodiment of the present invention will be described with reference to FIG. As shown in the figure, the terminal setting device 6 that issues a specific operation command to the blower device 4 is connected to the power line for supplying the power of the blower device 4.

In the above structure, the blower 4 connected to the power line of the same system can be controlled by the terminal setting device 6 which can output a signal on the power line.

As described above, according to the remote control device for an air conditioner of the second embodiment of the present invention, the blower device 4 can be operated by the terminal setting device 6 from any position as long as the system is the same on the power line. Therefore, if the outlet for the power line near the blower 4 is used, the blower 4 can be operated, so that the operation can be easily confirmed.

Next, a third embodiment of the present invention will be described with reference to FIG. It is a flow chart which blower equipment connected to the same system as shown in a figure conveys an operating state to controller 2.

In the above configuration, in step 1, it is recognized whether the blower device 4 itself has the smallest address in the same system. In step 2, the blower device 4 with the smallest address monitors the operation and stop states of all the blower devices 4 in the same system and stores the signals on the power line. In step 3, the blower 4 with the smallest address is in the state of all the blowers 4 from the state of all the blowers 4 if one is operating, otherwise it is in the stopped state.
Will send a signal to.

According to the remote controller for an air conditioner of the third embodiment of the present invention as described above, the motion state can be easily performed without grasping the operating states of all the devices connected to the same system on the controller 2 side. Since the software load on the controller 2 can be reduced because it can be known, and ON / OFF of driving can also be displayed by performing a simple display using the signal, it can be used as an indoor start / stop SW to prevent forgetting to turn it off. Can also be used.

[0026]

As is apparent from the above embodiments, according to the present invention, it is possible to communicate with each other without using a special signal line, and an inexpensive and easy-to-use air conditioner that does not require auxiliary equipment for communication. A remote control device for use can be provided.

Further, it is possible to provide a remote control device for an air conditioner in which remote control can be easily performed in the vicinity of the blower device and the moving body of each device can be easily confirmed.

Further, it is possible to provide a remote control device for an air conditioner which can know the operating state of the blower in the system without performing any special processing on the controller side.
