SUMMARY OF THE INVENTION An air conditioner control apparatus according to the present invention includes one outdoor unit, a plurality of indoor units to which addresses are assigned, and a plurality of remote controllers less than these indoor units. And a transmission line for transmitting signals by connecting the respective indoor units and between the respective indoor units and the respective remote controllers, and grouping the plurality of indoor units into a plurality of groups of one or more indoor units. In a control device for an air conditioner that is configured separately to control the operation of all the indoor units belonging to the group by the remote controller belonging to each group, the remote controller sets the number of indoor units to be operated. Corresponds to the addresses that are consecutive from the address of the setting switch and the indoor unit to which the remote controller is connected. It took measures of providing a group setting means for setting a constant has been the same group indoor unit number worth.

[0007] Further, one outdoor unit, a plurality of indoor units to which addresses are respectively given, a plurality of remote controllers less than these indoor units, between the indoor units, and between the indoor units and the remotes. And a transmission line for connecting the controllers to transmit a signal, the plurality of indoor units are divided into a plurality of groups each including one or more indoor units, and the remote controllers belonging to each of the groups configure the group. In the control device for an air conditioner that controls the operation of all the indoor units that belong to the remote controller, in addition to the addresses that are continuous with the addresses of the indoor units to which the remote controller is connected, other indoor units,
You may provide the search means which searches whether the said remote controller is connected, and the group setting means which sets the indoor unit to which the said remote controller is not connected to the same group.

[0008]

According to the present invention, by setting the number of indoor units operating in a group by the number setting switch on the remote controller, the remote controller can automatically set the number of indoor units for the group. .

If the remote controller searches for a remote controller other than its own address without providing a unit number setting switch, it is possible to automatically set a group of indoor units corresponding to the remote controller.

【Example】

Example 1. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram of an air conditioner according to this embodiment. 2 is a flow chart showing the operation of the control device for an air conditioner of the first embodiment according to the present invention, and FIG. 3 is the first embodiment.
FIG.

Next, this embodiment will be described with reference to FIGS. 1, 2 and 3. Similar to the conventional example, 1 is an outdoor unit, 2 is an indoor unit, 4 is a transmission line, 5 is a power supply for supply, 6 is a signal line for turning the compressor on / off of the outdoor unit, and 9 is an operation mode or each device. A liquid crystal display device for displaying the state, 10 is a run / stop switch, and 11 is a run mode switch. 12 is a remote controller of this embodiment, 13 is an address setting switch, and 14 is an indoor unit number setting switch. Like the conventional air conditioner, the indoor unit 2
Address setting is performed by the address setting switch 13 on the remote controller 12 and the remote controller 12, respectively. However, the indoor unit 2 is “1st” to “1+ (n + 1) th”, and the remote controller 12 is “101st” to “101+ (nth)”.
+1) ”, (n is the number of indoor units).

Next, when the power of each indoor unit 2 is turned on, the power is supplied to the remote controller 12 and the group setting can be performed. In step S4, the remote controller 12 reads the indoor unit number setting switch 14 on the remote controller 12, and in step S5, first, the indoor unit corresponding to its own address (for example, when the remote controller is "101", the indoor unit is "1"). )) As a group.

At step S6, the number setting switch 1
By subtracting "1" from the setting value of 4 and determining whether the setting value of the number setting switch 14 is "0" in step S7, if the setting value is "0", the setting is completed, and if it is not "0", "1" is added to the set value of the indoor unit address set in step S8 (in the above example, the indoor unit address is "2"), and the process returns to step S5 to set the indoor unit group.

Thereafter, by repeating this, the group setting is automatically performed from the remote controller. However, the group setting number of remote controllers is 16 at maximum, and the number setting switch 14 can be set up to 16 units.

Example 2. In the first embodiment, the group setting is performed by providing the remote controller with the number setting switch. However, as in the flow chart showing the operation of the control device for the air conditioner of the second embodiment shown in FIG. Addresses are set in advance by the address setting switch 13 in the indoor unit 2 and the remote controller 12, respectively. Next, by turning on the power of each indoor unit, power is supplied to the remote controller 12 and group setting can be performed.

In step S9, the internal constant X is set to 0, and in step S10, the indoor unit 2 for the own address (for example, the indoor unit is "1" when the remote controller is "101") is grouped, and step S11 is set.
Thus, the address of the indoor unit 2 set in the group is substituted into the internal constant Y. In step S12, "1" is added to each of the internal constants X and Y, and in step S13, the presence or absence of the remote controller 12 at the address of the value obtained by adding the internal constant X to the value of its own address is searched and set if there is any. finish. If not, the indoor unit 2 with the address of the internal constant Y (“2” in the above example) is determined in step S14.
Is set as a group, and the internal constant X is set in step S15.
If the value is "15", the setting is terminated, and if it is not "15", the process returns to step S12, and by repeating this, the group setting is automatically performed from the remote controller 12.

[0017]

As described above, according to the present invention, by setting the number of indoor units operating in a group by the number setting switch on the remote controller, the remote controller automatically groups the indoor units by the number. It is possible to set.

If the remote controller searches for a remote controller other than its own address without providing a unit number setting switch, it is possible to automatically set a group of indoor units corresponding to the remote controller.
