DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an address setting device and an address setting method for an air conditioner in which an outdoor unit and a plurality of indoor units and between the indoor unit and a remote controller are connected by signal transmission lines.

[0002]

2. Description of the Related Art In recent years, an address setting device for an air conditioner has been provided which automatically sets an address without requiring a worker to set an address when the air conditioner is installed.

A conventional air conditioner address setting device is disclosed in, for example, JP-A-63-61835.

Hereinafter, a conventional address setting device for an air conditioner will be described.

FIG. 7 shows an electric circuit diagram of an address setting device of the air conditioner. In FIG. 7, reference numeral 1 denotes an outdoor unit. Reference numerals 2a, 2b, and 2c denote indoor units, each having therein a photocoupler 4 for controlling address setting and an SCR 5 as switching means that is shut off after address setting. An AC voltage is applied to a series connection circuit of the photocoupler 4 and the SCR 5 connected in a configuration, and the connection between the indoor units 2a, 2b, and 2c by the connection between the photocoupler 4 and the SCR 5 is non-loop.
It is configured in a loop-shaped and non-branched shape. A signal transmission line 3 connects the outdoor unit 1 and the indoor units 2a, 2b, 2c.

The operation of the address setting device for an air conditioner configured as described above will be described below.

First, an address setting control signal is supplied from the outdoor unit 1 to the indoor units 2a, 2b and 2c through the signal transmission path 3, and the address is not set and the photocoupler 4 is turned off.
The indoor unit 2c in the state returns a response signal to the address setting control signal.

Then, the outdoor unit 1 that has received the response signal supplies an address setting signal to the indoor unit 2c. The indoor unit 2c sets its own address according to the address setting signal, turns off its own SCR 5, and returns an address confirmation signal to the outdoor unit 1 through the signal transmission line 3.

Next, when an address setting control signal is supplied again from the outdoor unit 1 to the signal transmission line 3, the photocoupler 4 of the indoor units 2b and 2c whose addresses have not been set is turned off.
The above-described series of operations is performed by the indoor unit 2b and the outdoor unit 1 in the FF state. This series of operations is repeated until no response signal is returned to the address setting control signal from the outdoor unit 1 to set the addresses of all the indoor units.

[0010]

However, in the conventional configuration, although address setting work is not required at the time of installation, a connection line for address setting is required between indoor units in addition to a signal transmission line, and a non-loop connection is required. Wiring must be connected in a non-branched manner, wiring work becomes complicated, and there is a high possibility that a connection is erroneously made. If an incorrect connection is made, an address cannot be set.

The present invention solves the conventional problems.
An object of the present invention is to provide an address setting device and an address setting method for an air conditioner that can easily set an address for each indoor unit.

[0012]

According to a first aspect of the present invention, there is provided an address setting apparatus for an air conditioner, wherein an outdoor unit is connected to a plurality of indoor units and between the indoor unit and a remote controller by a signal transmission line. The outdoor unit is an address setting device of an air conditioner that transmits an address setting signal to the indoor unit that has transmitted an address request signal, and each of the indoor units is from a corresponding remote controller. When an operation signal is first received after connection between the outdoor unit and the corresponding remote controller via the signal transmission line, an address request signal is transmitted to the outdoor unit, and the address setting is performed from the outdoor unit. When a signal is received, its own address is set based on the address setting signal.

In the above configuration, each of the indoor units transmits an address request signal to the outdoor unit upon receiving an operation signal from the remote control for the first time after the outdoor unit and the corresponding remote control are connected via the signal transmission line. Next, the outdoor unit that has received the address request signal sequentially transmits an address setting signal to each of the indoor units that has transmitted the address request signal. Next, each indoor unit that has received the address setting signal from the outdoor unit sets its own address based on the address setting signal. Therefore, the address of the indoor unit can be sequentially set only by connecting the outdoor unit and each indoor unit and between the indoor unit and the remote controller by the signal transmission line and performing the operation operation.

According to a second aspect of the present invention, there is provided an address setting method for an air conditioner in which an outdoor unit is connected to a plurality of indoor units and between the indoor unit and a remote controller by a signal transmission line. The method, wherein each of the indoor units receives an operation signal from the corresponding remote controller for the first time after the signal transmission line connects between the outdoor unit and the corresponding remote controller, A first step of transmitting an address request signal to the outdoor unit, and a second step of sequentially transmitting an address setting signal to each of the indoor units having transmitted the address request signal, wherein the outdoor unit having received the address request signal has And a third step in which each of the indoor units receiving the address setting signal from the outdoor unit sets its own address based on the address setting signal. And made of a flop, it is possible to sequentially set the address of the indoor unit only by the connecting between the outdoor unit and the indoor units and between the indoor unit and the remote control signal transmission line driving operation.
