Technical Field

The invention relates to the technical field of washing water detection for washing devices, in particular to a washing device with a TOC detection function.

Background

At present, for washing devices, such as washing machines, dish washing machines and the like, a turbidity sensor is generally adopted to measure the turbidity of washing water in washing, and whether clothes are washed cleanly is judged according to turbidity measurement data, wherein the turbidity represents the degree of suspended substances in water for blocking light transmission, the detection effect on insoluble substances in water is better, the more the insoluble substances in water are, the higher the turbidity is, so whether the clothes are washed cleanly is generally judged according to the low value of the turbidity, and a washing program is controlled; however, in washing, for example, in the existing washing process using washing liquid, detergent, etc., suspended substances in water are not main substances, and also surfactants of the washing liquid and dirt (organic additives) attached to the objects to be washed are present, so that the measured turbidity cannot completely represent the cleanness of the objects to be washed (clothes), and the water quality in the washing device cannot be truly reflected, and the existing washing device using a turbidity sensor cannot meet the actual washing requirement; therefore, there is a need for a washing device that can accurately determine the cleanliness of the washing water, especially a washing device that can more accurately determine the substances in the washing water.
