AIR CONDITIONER INDOOR UNIT CONTROL BOARD, AIR CONDITIONER INDOOR UNIT AND SPLIT-TYPE AIR CONDITIONER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/077694
Kind Code:
A1
Abstract:
An air conditioner indoor unit control board, an air conditioner indoor unit (10) and a split-type air conditioner system. A plurality of outdoor strong-current driving circuits are provided in a first board body (110) in the air conditioner indoor unit (10), such that driving control of a main working device of an air conditioner outdoor unit (20) is implemented at the air conditioner indoor unit (10); in addition, an indoor weak-current assembly of the air conditioner indoor unit (10) is connected to a display board body (120), and an indoor main controller (113) controls the indoor weak-current assembly by means of a display control chip (121) on the display board body (120), thereby optimizing the working environment of a driving circuit of the main working device of the air conditioner outdoor unit (20) while reducing control boards, eliminating the negative effects of the severe environment on the main working device of the air conditioner outdoor unit (20), and reducing the fault maintenance cost as well as the overall cost in the links among production, use and maintenance. Driving control of a strong-current assembly and the weak-current assembly is implemented at the first board body (110) and the display board body (120) respectively, such that separate driving control of the strong- and weak-current assemblies is enabled, effectively reducing or even eliminating misoperations caused by interference of strong current with weak-current signals.
