Abstract

The present invention provides a washing machine, including a wall part provided with a space filled with a washing liquid, a light sensor having a light-emitting element arranged outside the space to emit light to the cleaning liquid and a light-receiving element arranged outside the space to receive the light, and a support body having a first support part to support the light-emitting element, a second support part to support the light-receiving element and a bridge part, wherein the bridge part is connected with the first support part and the second support part so as to support the light-emitting element and the light-receiving element at relative positions, and the bridge part is configured to transversely cut the upper of the wall part. Thereby, the bridge part protects the light-emitting element and the light-receiving element from effect of dropping articles, e.g. dust or liquid droplets.

Description

technical field [0001] The present invention relates to a washing machine provided with a support capable of suitably protecting an optical sensor for detecting the state of washing liquid for washing laundry. Background technique [0002] In recent years, a wide variety of washing machines have been offered on the market. Some types of washing machines change the washing operation according to the state of the washing liquid detected by the sensor. Japanese Patent Laid-Open Publication No. Hei 5-96087 discloses a washing machine equipped with an optical sensor. The light sensor of this washing machine detects the turbidity of the washing liquid. The optical sensor is integrally formed with the drain tank of the washing machine, and the structure is relatively complicated. Such a structure is unsatisfactory in terms of manufacturing cost. Also, if the light sensor fails, it must be replaced along with the drain tank. As such, the optical sensor disclosed in this patent ...
