Automatic water level control system for an automatic washer |
摘要 |
An automatic water level control is provided which utilizes a single pneumatic pressure sensor for detecting minimum water level, maximum water level and tub motion during agitation. Relative tub movement change during agitation and filling is used to determine an optimum water level for washing. A horizontal portion of the sensor fills with water during the tub filling process and provides the arrangement for detecting tub motion. A microprocessor stores and compares successive peak pressure signals to determine relative changes in tub motion amplitude.
