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.
