  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a configuration diagram of a control device for an air conditioner according to Embodiment 1 of the present invention. The air conditioner in the present embodiment is composed of an outdoor unit arranged outdoors and an indoor unit arranged indoors, and the outdoor unit control device 1 is arranged in the outdoor unit. An indoor unit control device 6 is arranged. Therefore, the control device for an air conditioner according to the present invention includes an outdoor unit control device 1 and an indoor unit control device 6.

  Next, the configuration of the outdoor unit control device 1 will be described. The outdoor unit control device 1 includes an outdoor power supply unit 3 connected to a commercial power supply 5. Furthermore, it has the outdoor control part 2 comprised with the microcomputer 21 and its peripheral circuit which control an outdoor unit, and the outdoor communication part 4 which communicates with an indoor unit.

  On the other hand, the indoor unit control device 6 includes an indoor power supply unit 8 to which power is supplied from the outdoor power supply unit 3, a microcomputer 18 that controls the indoor unit, and an indoor control unit 9 that includes peripheral circuits thereof, It has the indoor communication part 7 which communicates with an outdoor unit.

  The indoor power supply unit 8 includes a transformer 15, an electrolytic capacitor 16, a constant voltage power supply 17, and a diode bridge 19, and the indoor communication unit 7 includes a communication coupler 20.

  And the outdoor power supply part 3 and the indoor power supply part 8 are connected by the 1st indoor / outdoor connection electric wire 11 and the 2nd indoor / outdoor connection electric wire 12, and the outdoor communication part 4 and the indoor communication part 7 are the 1st. The two indoor / outdoor connecting wires 12 and the third indoor / outdoor connecting wire 13 are connected.

  In the control device for an air conditioner configured as described above, in the present invention, the power supply switching device 14 is arranged in the first indoor / outdoor connection electric wire 11, and the power supply switching device 14 is on / off controlled. Thus, the power supply from the commercial power supply 5 to the outdoor power supply unit 3 is started / stopped. That is, power supply to the outdoor power supply unit 3 is started by controlling the power supply switching device 14 to be on, and power supply to the outdoor power supply unit 3 is stopped by controlling the power supply switching device 14 to be off.

  Hereinafter, the operation of the control device for an air conditioner of the present invention will be described.

  First, electric power is supplied from the outdoor power supply unit 3 connected to the commercial power supply 5 to the indoor power supply unit 8 through the first indoor / outdoor connection wire 11 and the second indoor / outdoor connection wire 12. In the indoor power supply unit 8, the diode bridge 19 and the transformer 15 convert AC power into DC power and output NR power.

The NR power is input to the constant voltage power supply 17, and 5V power for operation of the microcomputer 18 and the communication coupler 20 is output. The microcomputer 18 is output with the output 5V power.
And the communication coupler 20 can be operated.

  The outdoor communication unit 4 is connected to the indoor communication unit 7 through the second indoor / outdoor connection wire 12 and the third indoor / outdoor connection wire 13, and exchanges data such as operation information.

  Next, the operation of the power supply switching device 14 when the operation of the air conditioner is stopped will be described. FIG. 2 is a diagram illustrating a timing chart of each component when the operation is stopped.

  First, when the operation is stopped, the outdoor control unit 2 disposed in the outdoor unit performs on / off control of the power switching device 14.

  Then, by turning on the power supply switching device 14 immediately after the operation is stopped, the electrolytic capacitor 16 is charged, NR power is output by the amount of the charged charge, and 5 V power is output by the constant voltage power supply 17. .

  Then, by turning on the power supply switching device 14 for a preset charging time, charging of the electrolytic capacitor 16 is completed, and after the preset charging time has elapsed since the power supply switching device 14 was turned on, the power supply switching device 14 is turned off.

  However, the NR power gradually decreases with the power supply to the indoor control unit 9 and the indoor communication unit 7. Therefore, in the present invention, the specified value of the NR power necessary for the operation of the constant voltage power supply 17 after the electrolytic capacitor 16 is fully charged (in the present invention, it is described as 5 V, but is not limited thereto). Is calculated in advance, and the power supply switching device 14 is turned on each time the precalculated time elapses.

  With this configuration, the indoor communication unit 7 and the indoor control unit 9 can be operated at all times, so that it is possible to respond to a driving instruction from the remote controller 10 while suppressing power consumption.

(Embodiment 2)
FIG. 3 is a configuration diagram of an air conditioner control device according to Embodiment 2 of the present invention, and FIG. 4 is a timing chart of each component when the operation of the air conditioner according to Embodiment 2 is stopped. In addition, about the same component as Embodiment 1, the same code | symbol as Embodiment 1 is attached | subjected and the description is abbreviate | omitted.

  The difference from the first embodiment is that the power supply switching device 14 is arranged on the second inner / outer connection electric wire 12.

  First, when the operation of the air conditioner is stopped, as in the first embodiment, NR power is output by the amount of electric charge charged in the electrolytic capacitor 16, and 5 V power is output from the constant voltage power supply 17. At this time, when the indoor control unit 9 receives a signal such as an operation start from the remote controller 10, signal information is temporarily stored in the microcomputer 18 in the indoor control unit 9.

  In the second embodiment, since the power supply switching device 14 is arranged on the second indoor / outdoor connection wire 12 for exchanging information, communication is performed indoors and outdoors while the power supply switching device 14 is controlled to be off. It cannot be done.

  Therefore, since it is necessary to perform communication between the outdoor unit and the indoor unit at the timing when the next power supply switching device 14 is turned on, it is necessary to temporarily store it in the microcomputer 18.

  As described above, the present invention can provide a control device for an air conditioner that can accept a request from a remote controller even when operation is stopped while suppressing power consumption.

(Embodiment 3)
FIG. 5 is a configuration diagram of an air conditioner control device according to Embodiment 3 of the present invention, and FIG. 6 is a timing chart of each component when the operation of the air conditioner according to Embodiment 3 is stopped. In addition, about the same component as Embodiment 1, the same code | symbol as Embodiment 1 is attached | subjected and the description is abbreviate | omitted.

  The difference from the first embodiment is that the power source switching device 14 is provided in the indoor control device 6 and the power source switching device 14 is controlled by the indoor control unit 9.

  Even if comprised in this way, the control apparatus of the air conditioner which can receive the request | requirement from a remote control can be provided, even if it is a time of operation stop, suppressing power consumption.
