Description
Technical field
The present invention relates to a kind of filter, is a kind of small-sized Novel water tank of cheapness specifically.The invention still further relates to a kind of cleaning method of water tank.
Background technology
Along with the progressively quickening of urbanization process, the high buildings and large mansions of various places are all rised sheer from level ground, the safety of tap water supply, the care that energy saving is more and more subject to owner.General supply equipment is divided into water tank pressurization and supplies water and supply water two kinds without negative pressure booster, but these two kinds of modes have pluses and minuses.See the following form:
The main pluses and minuses of table one way of supplying water
Can be found by upper table, although non-negative pressure water-supply installation has well solved water safety problem, due to water-holding capacity extreme difference, cistern water supply mode is also being used widely.
Summary of the invention
Purport of the present invention, for overcoming the deficiencies in the prior art, provides a kind of Novel water tank and water tank cleaning method.
To achieve these goals, according to the present invention by the following technical solutions:
