The invention provides an energy-saving central air conditioner, which belongs to the technical field of central air conditioners, and comprises an air conditioner body and a pipeline arranged at the lower end of the air conditioner body, and further comprises an air inlet adjusting
assembly, an induction dust collecting
assembly and a cleaning and collecting
assembly, air is purified through
electrostatic adsorption of the adsorption plate, dust accumulation and local blockage conditions are accurately detected through cooperation of an elastic part, a
magnetic coating and a Hall sensor, the air inlet quality of the air conditioner and
system operation are prevented from being affected by feedback signals, tiny impurities can be effectively captured by the adsorption plate, and the air cleanliness is improved; a
wind power and knocking combined mode is adopted for dust removal, a filter screen plate and an adsorption plate are cleaned in all directions, and inlet air cleanliness is guaranteed; when the ash discharging port is not used for removing ash, the magnetic blocking plate blocks the ash discharging port to prevent leakage, and the pressing rod limits the position of the connecting plate to ensure the monitoring precision of the sensing rod, reduce part shaking, prevent dust from falling off in advance and ensure the
adsorption effect; the baffle is connected with related parts to control the opening degree of the pipeline, dust is prevented from entering the wall during dust removal, and dust collection is guided.
