Clothes dryer and control method therefor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clothes dryers face issues with lint accumulation, which can obstruct airflow, reduce drying efficiency, and potentially cause device failure, necessitating a method to notify users when the filter needs cleaning.
Innovation Solution
A clothes dryer system incorporating a filter sensor to detect the mounting state of the filter, a processor to record changes in the filter's state, and a display to notify users when the filter requires cleaning, ensuring accurate management and prevention of potential problems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter is not cleaned regularly, then lint accumulates and may exit the filter to enter electronic components, but frequent cleaning notifications may annoy users
Solution Approach 1:
The sensor detects and records filter mounting state changes in advance, allowing the system to notify users before lint accumulation becomes problematic. This proactive approach prevents lint from entering electronic components while providing timely, relevant notifications to users
2Measurement precision
If a sensor and control system are added to monitor filter state, then accurate filter management is achieved, but device complexity increases
Solution Approach 1:
The patent extracts the monitoring function into a separate sensor component and the control logic into a dedicated control unit, isolating these functions from the main dryer system. This modular approach enables precise filter state detection while keeping the overall system structure manageable and maintainable

AI summary
A clothes dryer comprising: a cabinet; a control panel including a power button and a display; a drum rotatable inside the cabinet; a filter to filter air discharged from the drum; a filter sensor to detect a mounting state of the filter and output a detection signal based on the mounting state of the filter detected; a memory to record a change in the mounted state of the filter as an event based on the mounting state of the filter detected by the filter sensor; and a processor to communicatively connect to the control panel, the filter sensor, the memory, and to control the display so that the display displays a notification related to the management of the filter based whether the event due to the change in the mounting state of the filter is recorded in the memory.
