Method and device for detecting filth blockage state of filtering part of clothes drying equipment and clothes drying equipment

Abstract

The invention provides a method and device for detecting the filth blockage state of a filtering part of clothes drying equipment and the clothes drying equipment. The method for detecting the filth blockage state of the filtering part of the clothes drying equipment comprises the steps that the clothes drying equipment is selected to be in a clothes drying mode; the real-time running power Pc ofthe clothes drying equipment is acquired; the acquired real-time running power Pc is compared with the rated power Ps of the clothes drying equipment; when Ps-Pc is larger than or equal to delta P1, delta P1 is a first power preset difference value, first warning information is sent out, and the first warning information is used for informing a user that the filtering part of the clothes drying equipment is in a first filth blockage state. According to the method and device for detecting the filth blockage state of the filtering part of the clothes drying equipment and the clothes drying equipment, the filth blockage state of the filtering part of the clothes drying equipment is judged by detecting the real-time running power of the clothes drying equipment, the user can be reminded to carry out cleaning operation more timely, and then the working efficiency and the use safety of the clothes drying equipment are improved.

Description

technical field [0001] The invention belongs to the technical field of household electrical appliances, and in particular relates to a method and device for detecting the dirty state of a filter part of a clothes dryer, and a clothes dryer. Background technique [0002] With the continuous improvement of people's living standards, drying equipment (all-in-one washing and drying machines or clothes dryers) has been gradually developed to meet the people's special drying needs. However, in the drying process of current clothes dryers, lint will inevitably be produced, and the lint produced will fall off from the clothes to be dried, and will flow in the drying channel with the flow direction of the airflow, and the drying process will be completed. The temperature of the air flow is realized by the PTC heating module. In order to prevent the aforementioned lint from adhering to the components in the drying air duct, in the prior art, corresponding filter assemblies (such as fi...

And when the user fails to clean the filter assembly in time, the filter assembly will be blocked. At this time, the drying air cannot form an effective flow cycle under the rotation of the drum, and the surface wind speed of the PTC heating module will be reduced, which will lead to heat loss of the PTC heating module. The amount of radiation rises sharply, which causes the drying temperature in the drum to rise sharply, which in turn causes the corresponding temperature limiter set in the equipment to be triggered by the high temperature protection mode, and the corresponding heating module will stop running (stop heating), leaving only the drum The rotating drive motor works, the drying efficiency is poor or even has no drying effect, and the temperature inside the drum is high, which may damage the drying equipment and the clothes to be dried. Therefore, how to timely check the dirt and blockage of the filter parts of the drying equipment It is particularly important to detect
