The present invention controls the switching of first, second control power switch respectively through indoor control unit; The energising and the outage of driver element and outdoor driver element in the realization control room; When standby; Indoor control unit is controlled first, second control power switch respectively and is broken off, and cuts off the power supply of devices such as indoor driver element and outdoor driver element, reduces the loss of electric energy of the microprocessor operation of self simultaneously; Reach the few use and the obsolete purpose of electric energy, satisfy the purpose that all is in the minimum energy loss at each state of whole air-conditioning; When the indoor microprocessor of indoor control unit is in the sleep pattern, be in resting state, have only externally and just recover normal operating condition under the down trigger.
Description of drawings
Fig. 1 is the schematic diagram of the control system of convertible frequency air-conditioner of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment detailed description is done by the control system of convertible frequency air-conditioner of the present invention.
Embodiment
The schematic diagram of the control system of convertible frequency air-conditioner of the present invention is shown in accompanying drawing 1; Indoor driver element 1, outdoor driver element 2, indoor control unit 3, outdoor control unit 4, the first control power switch 5, second control power switch 6, Switching Power Supply 7 and the indoor display unit 8; Wherein outdoor driver element 2 is connected with outdoor control unit 4; Outdoor control unit 4 is electrically connected with the city, and the connecting circuit between outdoor control unit 4 and the civil power is provided with the second control power switch 6; The input of Switching Power Supply 7 is electrically connected with the city; The output of Switching Power Supply 7 is connected with indoor driver element 1, indoor control unit 3 and indoor display unit 8 respectively; Connecting circuit between indoor driver element 1 and the Switching Power Supply 7 is provided with the first control power switch 5; The output of the indoor control unit 3 first control power switch 5, second is respectively controlled power switch 6 connections, in the present embodiment, and indoor display unit 8 and the indoor driver element 1 shared first control power switch 5.
In the present embodiment; Civil power is A.C 220V; The device of indoor and outdoors is given in power supply simultaneously, and indoor control unit 3, indoor driver element 1 and indoor display unit 8 carry out power distribution by Switching Power Supply 7 respectively, during work; Switching Power Supply 7 is exported D.C 5V to indoor control unit 3, and to indoor driver element 1 and indoor display unit 8 output D.C 12V.
Above-mentioned indoor control unit 3 is built-in with indoor microprocessor MCU1; Outdoor control unit 4 is built-in with outdoor microprocessor MCU2; Indoor microprocessor MCU1 controls as core, controls the Kai Heguan that the first control power switch 5, second is controlled power switch 6 by it.
