Принадлежит:

A turbidity sensor assembly for a dishwasher appliance is provided. The turbidity sensor assembly measures the turbidity of wash fluid in a manner similar to conventional turbidity sensors, but also includes an integral water level indicator. The water level indicator is an opaque buoyant ball that rises and falls with the water level to provide a water level indication that can be used to shut off the drain pump when the sump is empty. More specifically, when the water level drops below a predetermined level, the opaque ball blocks the transmission of light between the emitter and receiver of the turbidity sensor, thus indicating that the sump is almost empty. As a result, the pump operating during a drain cycle need only operate long enough to drain the sump, and this may be achieved without an additional measuring device or complicated control system. 1. A dishwasher appliance defining a vertical direction , a lateral direction , and a transverse direction , the dishwasher appliance comprising:a wash chamber for receipt of articles for washing;a sump positioned adjacent a bottom of the wash chamber, the sump configured for collecting wash fluid;a pump in fluid communication with the sump, the pump being configured for discharging the wash fluid from the dishwasher appliance during a drain cycle; and a housing defining a channel in fluid communication with the wash fluid;', 'an emitter and a receiver positioned within the housing on opposite sides of the channel;', 'a buoyant object positioned within the channel; and', 'a retention device configured to enable the buoyant object to move along with the level of the wash fluid within the channel along the vertical direction between a raised position and a lowered position., 'a turbidity sensor assembly configured for measuring a turbidity and a level of wash fluid in the sump, the turbidity sensor assembly comprising2.
