Automatic backwashing water purifier

Abstract

The invention discloses an automatic backwashing water purifier which comprises electromagnetic valves, a circulating pressure pump, an RO (reverse osmosis) device and a water storage tank. One electromagnetic valve is arranged on a producing water pipeline at a producing water end of the RO device, the producing water end of the RO device is connected with the water storage tank through the electromagnetic valve on a water inlet pipeline of the water storage tank and connected with a circulating pressure pump through the electromagnetic valve on a producing water pipeline of an RO film, one electromagnetic valve for controlling a water source is arranged on a water inlet pipeline of the RO device, the water source enters the RO device through the electromagnetic valve on the water inlet pipeline of the RO device and is purified and filtered, the electromagnetic valve is arranged on the water inlet pipeline of the water storage tank, producing water of the RO film enters the water storage tank through the electromagnetic valve on the water inlet pipeline of the water storage tank, the water storage tank is provided with a TDS (total dissolved solid) sensor, the other end of the circulating pressure pump is connected with the producing water pipeline of the water storage tank, and the electromagnetic valve for controlling water discharge is arranged at the tail end of the producing water pipeline of the water storage tank. The automatic backwashing RO water purifier is clear in structure, and the service life of a water purifying filter element is greatly protected.

Description

technical field [0001] The invention relates to the field of household water purifiers, in particular to an automatic backwashing water purifier. Background technique [0002] At present, the backwashing of water purifiers and water purification equipment on the market is flushed with municipal tap water, which is not only unsatisfactory, but also causes secondary blockage of the filter element, which further affects the purification and filtration function of the filter element itself. [0003] The invention provides an automatic backwashing water purifier and its method. The water produced by the water purifier itself is used to backwash the filter core, which not only achieves remarkable filtration but also fundamentally prevents secondary pollution during the purification process of the water purifier. Contents of the invention [0004] The technical solution of the present invention is to provide a water purifier and method with the following structure, including elec...
