Abstract

The invention discloses a water scale detection method and device, a water scale detector and a thermodynamic system. The method comprises the steps that an infrared emission signal is emitted, and areflection signal generated based on the infrared emission signal is received; intensity information of the reflected signal is determined; and whether water scales are deposited in the to-be-detectedpipeline is determined according to the intensity information of the reflected signal. By implementing the method, whether water scales are deposited in the pipeline of the thermal equipment or not can be detected in real time, the situation that the working performance of the thermal equipment is affected by water scale deposition is effectively avoided, and the working efficiency and operationsafety of the thermal equipment are guaranteed.

Description

technical field [0001] The invention relates to the field of intelligent household appliances, in particular to a scale detection method, device, scale detector and thermal system. Background technique [0002] Because hard water is usually added during the use of thermal equipment, and as the thermal equipment works, the hard water in the thermal equipment will gradually boil or approach boiling, so that the minerals contained in the hard water adhere to the thermal equipment and gradually form scale. The thermal conductivity of scale is very poor. If the scale formed in the thermal equipment is too thick, the heating efficiency will be reduced, thereby wasting fuel or electricity. If it is serious, it will cause the tube burst of the thermal equipment and cause an accident. Since the scale in the thermal equipment cannot be monitored in real time, it is usually used to regularly clean the pipelines of the thermal equipment, but there are still problems of incomplete cleani...
