Abstract: The present invention provides a water quality sensor for household appliance which is installed inside of a washing appliance, including a housing and a detecting module contained therein. The detecting module includes a light emitting element for emitting a detecting beam passing through the transparent panel, and a light receiving element for receiving a backscattered beam generated from the detecting beam and backscattered by the cleaning medium. The light emitting element and the light receiving element are positioned on a same plane of a circuit board parallel to the transparent panel, and the detecting beam emitted from the light emitting element is blocked by a sensor holder from being directly received by the light receiving element, such that the water quality sensor determines the water quality of the cleaning medium contained in the household appliance based on the backscattered beam.

Abstract: A water quality sensor includes a housing including a light transmissive bucket mounted in an electrical washing appliance and a light transmissive inner barrel mounted in the bucket, an actuation module mounted in the inner barrel for detecting a water quality of a washing solution in the electrical washing appliance. Thus, if the bucket is cracked during manufacturing or due to a collision, the actuation module can still be well protected by the inner barrel, so that the washing solution in the electrical washing machine does not directly flow into and contact with the actuation module to cause an accidental short circuit of the circuit substrate of the actuation module, improving the water resistance and service life of the water quality sensor.

Abstract: A water quality sensor includes a housing having two hollow protruding portions, and a sensing module including a circuit board mounted inside the housing and having two positioning plates respectively positioned in the two hollow protruding portions, two identical connectors respectively mounted on the two positioning plates of the circuit board in reversed directions with a phase difference of 180 degrees therebetween, and a light emitter and a light receiver respectively mounted in the connectors to face toward each other for water quality detection. Thus, the invention allows the implementation of automated assembly to replace manual assembly, reducing the risk of human error, saving much labor and production costs, improving product quality and increasing product yield.
