Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an address setting device for an air conditioner.

[0002]

2. Description of the Related Art Recently, as an address setting device for an air conditioner, an automatic address setting device that does not require an operator to set an address when installing the air conditioner is provided.
A conventional address setting device for an air conditioner is disclosed in, for example, Japanese Patent Laid-Open No. 63-61835.

A conventional address setting device for an air conditioner will be described below. FIG. 7 shows an electric circuit diagram of the address setting device of the air conditioner. In FIG. 7, 1
Is an outdoor unit. 2a, 2b, 2c are indoor units, and internally include a photocoupler 4 for address setting control and an SCR 5 as a switching unit that is shut off after address setting. AC voltage is applied to the series connection circuit of the photocoupler 4 and the SCR 5 which are connected in the configuration and the photocoupler 4 and the SCR 5 are connected.
The connection between the indoor units 2a, 2b, 2c by the connection with the CR5 is non-looped and non-branched. A signal transmission line 3 connects the outdoor unit 1 and the indoor units 2a, 2b, 2c.

The operation of the address setting device of the 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, 2c through the signal transmission path 3 and the photocoupler 4 is turned off because no address is set.
The indoor unit 2c in the state returns a response signal to the address setting control signal.

The outdoor unit 1 receiving 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 again supplied from the outdoor unit 1 to the signal transmission line 3, the photocoupler 4 of the indoor units 2b and 2c in which the address is not set becomes O.
The series of operations described above is performed by the indoor unit 2b and the outdoor unit 1 that are 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, and the addresses of all the indoor units are set.

[0008]

However, in the conventional configuration, although the address setting work is not required at the time of installation, a connection line for address setting is required between the indoor units, in addition to the signal transmission line, and the non-looping is required. Since the wiring must be connected in a fixed and non-branched manner, the wiring work is complicated and there is a high possibility that the connection will be erroneous, and the address cannot be set if the connection is erroneously apologized.

The present invention solves the conventional problems.
An object of the present invention is to provide an address setting device for an air conditioner in which a signal transmission line is connected without any restriction on the connection form and a sequential address is set only by a driving operation, and the work for address setting is unnecessary. .

[0010]

In order to achieve this object, an address setting device for an air conditioner according to the present invention is an outdoor transmission in which an address setting signal is sequentially transmitted to an outdoor unit to an indoor unit that has transmitted an address request signal. Means and multiple indoor units,
When the address is not set, the indoor receiving means for receiving the operation signal of the remote controller and outputting the signal, the indoor transmitting means for transmitting the address request signal by the signal from the indoor receiving means, and the address setting signal transmitted by the outdoor transmitting means And a control unit for setting the own address.

In addition to the above configuration, the address setting device for an air conditioner according to another aspect of the present invention has, in addition to the above configuration, an address transmitting means for receiving an address display signal and transmitting address data to an indoor unit, and a predetermined display on a remote controller. It is provided with transmitting means for transmitting an address display signal by an input and a display section for receiving and displaying address data transmitted by the address transmitting means.

Further, in addition to the above configuration, the address setting device for an air conditioner according to another aspect of the present invention changes the address of the indoor unit displayed on the display unit by a predetermined change input to the remote controller and addresses the changed address. An address changing means for transmitting as a setting signal is provided.

[0013]

According to the present invention, the indoor unit transmits the address request signal in response to the operation signal from the remote controller and sets its own address based on the address setting signal from the outdoor unit. The addresses of the indoor units can be sequentially set only by connecting the indoor units and the indoor unit and the remote controller with a signal transmission line and performing a driving operation.

According to another aspect of the present invention, the remote controller further transmits an address display signal by a predetermined display input to display address data from the indoor unit. The address setting status of the indoor unit can be confirmed.

Further, according to another aspect of the present invention, since the address setting signal is transmitted from the address changing means of the remote controller by a predetermined change input, the address can be arbitrarily changed by the remote controller.

14c, 1 provided with address transmission means 51, 52
Reference numeral 5c is a remote controller, which is provided inside the transmitting means 24 and 2, respectively.
5, display sections 34 and 35, and address changing means 44 and 45 for changing the address of the indoor unit displayed on the display sections 34 and 35 by a predetermined change input and transmitting the changed address as an address setting signal. ing.

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.

Indoor unit 11 for which no address is set
b and 12b receive an operation signal of the remote controller, an address setting operation (operation from Step 31 to Yes after branching to Step 37) and a predetermined display input to the remote controllers 14c and 15c, the indoor units 11b and 12b. The operation up to displaying the address (operation from step 38 to Yes after branching to step 38) is the same as the operation of the second embodiment (operation from step 11 to step 23), and therefore description thereof will be omitted. .

In this embodiment, for example, it is assumed that a predetermined change input is made on the remote controller 14c. The address setting means 44 of the remote controller 14c detects the change input (Yes in step 44).
The address displayed on the display unit 34 is changed (step 45). Then, the changed address is transmitted as an address setting signal (step 46).

On the other hand, the control unit 41 of the indoor unit 11b receives the address setting signal (step 47 branches to Yes) and sets its own address (step 48).

This series of operations is repeated until there is no predetermined change input (until step 44 is branched to No), and the address of the indoor unit is changed to an arbitrary address.

[0042]

As described above, according to the present invention, the outdoor unit has the outdoor transmitting means for sequentially transmitting the address setting signal to the indoor unit which has transmitted the address request signal, and the plurality of indoor units.
