A conventional air conditioner address setting device will be described below. FIG. 5 shows an electric circuit diagram of the address setting device of the air conditioner. In FIG. 5, 1
Is an outdoor unit. Reference numerals 2a, 2b, and 2c denote indoor units, each of which includes a photocoupler 4 for controlling address setting and an SCR 5 as switching means that is shut off after address setting. The photocoupler 4 is paired with the SCR 5 of another indoor unit. AC voltage is applied to the series connection circuit of the photocoupler 4 and the SCR 5 connected in
The connection between the indoor units 2a, 2b, 2c by the connection with the CR5 is configured in a non-loop 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.

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 the 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.

[0008]

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. Since the connection must be made in the same manner, the wiring work is complicated and the connection is likely to be erroneously made. If the connection is made incorrectly, the address cannot be set.

The present invention solves the conventional problems.
It is an object of the present invention to provide an address setting device for an air conditioner that can be set by simply connecting a signal transmission line without restricting a connection form and that does not require an address setting operation.

[0010]

The priority of the address setting request signal transmitted from the indoor transmitters 21, 22, 23 of the own indoor unit is compared with the priority of the address setting request signal transmitted from the other indoor unit. This is a communication monitoring device that outputs a contention loss signal when the priority is lower than the priority.

The indoor receiving means of the outdoor unit to which the communication monitoring devices 31, 32, 33 do not output the competitive loss signal receives the address setting signal and recognizes the address.

The operation of the address setting device for an air conditioner configured as described above will be described below with reference to the flowchart of FIG.

When the outdoor unit 14 transmits an address setting start signal from the outdoor transmitting means 15 (step 11), the indoor receiving means 41, 42, 43 of the indoor units 11, 12, 13 to which no address is set, set the address. The start signal is received and a signal is output (steps 1 and 2). In response to the signal, each of the indoor transmission means 21, 22, and 23 starts transmitting an address setting request signal including arbitrary data (step 3).

Next, each of the communication monitoring devices 31, 32, and 33 compares the address setting request signal transmitted by itself with the address setting request signal signal transmitted from another indoor unit (step 4), and sets its own address. If the priority of the request signal is low, the contention loss is detected and a contention loss signal is output (after branching from step 5 to the Yes side, step 9).

In this embodiment, for example, it is assumed that the address setting request signal transmitted from the indoor unit 11 has the highest priority. The communication monitoring devices 32 and 33 of the indoor units 12 and 13 detect the contention loss and transmit the contention loss signal to the indoor transmission units 21 and 13, respectively.

The outdoor unit 14 transmits an address setting signal which is a response signal to the address setting request signal from the outdoor transmitting means 15 (after branching from step 12 to the Yes side, step 13). Each of the indoor units receives the address setting signal in the indoor receiving means 41, 42, and 43, and only the indoor receiving means 41 having no input of the competitive losing signal when transmitting the address setting request signal receives its own address based on the address setting signal. Is set (after branching from step 7 to the Yes side, step 8).

Next, the indoor transmitters 22 and 23 of the indoor units 12 and 13 which have not transmitted the address setting request signal because the address has not been set start transmitting the address setting request signal (from step 10 to step 10). 3) The above series of operations are performed according to the priority of each address setting request signal.

This series of operations is repeated until each indoor unit no longer transmits the address setting request signal, so that the addresses of all the indoor units can be set.
