Water inflow measurement

摘要

Water admission to a washing machine is actuated by the programming unit and is designed to pass water at an average flow rate independent of pressure fluctuations in the mains. A reference level sensor in the washing machine defines a reference amt. of water independent of the loaded state of the drum. At the start of a program, a reference time is measured which is reqd. to admit the reference amt. of water. The amt. reqd. for a program section is determined by an admission time, calculated from the reference time and the reference water amt.
