Title:
FLUSHING SYSTEM AND METHOD OF ENERGY-SAVING FLUSHING
Document Type and Number:
WIPO Patent Application WO/2018/171102
Kind Code:
A1
Abstract:
A flushing system and a method of energy-saving flushing in the field of bathroom fixtures. The flushing system comprises a control valve (1), a first vapor coupling valve (21), a second vapor coupling valve (22), a one-piece valve (3), a first constant pressure tank (41) and a second constant pressure tank (42). Two ends of the one-piece valve (3) respectively connect to the first vapor coupling valve (21) and the second vapor coupling valve (22). The other end of the first vapor coupling valve (21) connects to a first branch tube (51). The first branch tube (51) extends into the first constant pressure tank (41) from the top of the first constant pressure tank (41). The other end of the second vapor coupling valve (22) connects to a second branch tube (52). The second branch tube (52) extends into the second constant pressure tank (42) from the top of the second constant pressure tank (42). The control valve (1) connects to the first vapor coupling valve (21) by means of a drainage tube (6). A limiting outlet (211) of the first vapor coupling valve (21) connects to the second vapor coupling valve (22) by means of a flow-dividing tube (7). An advantage of the invention is to realize time-delayed flushing of two water outlets by using the control valve (1) to control time-delayed opening of the two vapor coupling valves, by means of the linkage between the limiting outlet (211) and the flow-dividing tube (7), and as a result, the invention saves energy.
