Numerical control household ultrafiltration drinking fountain

Abstract

The invention discloses a numerical control household ultrafiltration drinking fountain, solving the problem of the existing device that the filtered impurities are inconvenient and incomplete to clean. The drinking fountain contains a quartz sand filter (8), an activated carbon filter (11), a Siliphos filter (14), a precision filter (16), an ultrafiltration filter (23) and a water tank (53), wherein water passes through a raw water pump (3) and a water inlet check valve (4) in turn through a raw water inlet (1) to enter the quartz sand filter (8) and then passes through the activated carbon filter (11), the Siliphos filter (14), the precision filter (16) and the ultrafiltration filter (23) in turn to enter the water tank (53). The quartz sand filter (8) and the activated carbon filter (11) are both provided with raw water backwashing pipelines; and the ultrafiltration filter (23) is provided with a cleaning pipeline which uses the primarily filtered water for backwashing. The drinking fountain can provide drinking water, warm water and boiling water under the intelligent control of the programmable logic controller (PLC); and by adopting the invention, the water purifier can be cleaned intelligently and efficiently.

Description

technical field [0001] The invention relates to a water purification device, in particular to a drinking water purification device. Background technique [0002] Household drinking water purification equipment has been relatively popular, but the existing equipment has the problem of inconvenient and incomplete removal of filtered impurities, especially the impurities filtered out by multiple layers cannot be automatically removed separately, so that the water provided by the water dispenser Boiled water and warm water are not up to the drinking standard, and there are also defects of wasting water and poor cleaning effect when cleaning the water dispenser. Contents of the invention [0003] The numerically controlled household ultrafiltration direct drinking water dispenser provided by the present invention solves the problems of inconvenient and incomplete removal of filtered impurities in existing equipment, so that the boiled water and warm water provided by the drinki...
