AI Technical Summary

Technical Problem

Existing laundry treating apparatuses struggle to accurately measure contamination levels, leading to washing times being set too long or too short, and fail to distinguish between different contamination levels, resulting in inadequate washing.

Method used

The apparatus incorporates a dust sensor, gas sensor, turbidity sensor, conductivity sensor, and spectroscopic sensor to measure contamination levels, with a controller calculating an expected washing time based on these measurements and adjusting operations accordingly.

Benefits of technology

This approach allows for precise determination of washing time based on contamination levels, ensuring thorough cleaning without excess water or energy use.

Abstract

A laundry treating apparatus (10) according to the present disclosure includes a main body (20), a washing tub, a door (30), a driver (70), a water supply unit (50), a drain unit (60), a sensor unit (100) and a controller (200). The sensor unit (100) includes a dust sensor (110) for measuring a dust concentration inside a washing tub, a gas sensor (120) for measuring gas components inside the washing tub, a turbidity sensor (150) for detecting a water quality of the washing water contained in the washing tub, a conductivity sensor (140), and a spectroscopic sensor (130). The controller (200) controls the driver (70), the water supply unit (50), the drain unit (60) and the sensor unit (100) and calculates an expected washing time based on data measured through the sensor unit (100) and the driver (70).
