Temperature control method and apparatus for clothes dryer, clothes dryer and storage medium
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clothes dryers struggle to precisely control temperature during the initial heating phase due to a lag in temperature measurement by the inside-drum sensor, leading to overheating and potential damage to clothes.
Innovation Solution
Implementing a temperature control method where the inside-drum heater starts heating until a preheating temperature value is reached, then stops, and resumes heating according to a preset drying temperature value, with the preheating temperature being lower than the drying temperature to ensure accurate temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the inside-drum temperature sensor is used to control the inside-drum heater, then the temperature control system is simple, but the temperature measurement has lag causing the heater to overheat clothes
Solution Approach 1:
The patent applies preliminary action by performing a cold compensation operation before the main drying process. The controller pre-calculates a compensation value based on the relationship between drum temperature and sensor measurement temperature, then subtracts this compensation from the target drying temperature to generate an adjusted heating target. This anticipates the sensor lag and compensates for it in advance, preventing overheating while maintaining system simplicity.
2Ease of operation
If the heater heats until the sensor reaches the drying temperature, then the control logic is simple, but the actual drum temperature exceeds the drying temperature causing clothes damage
Solution Approach 1:
The patent implements feedback by continuously monitoring the sensor temperature and comparing it against the adjusted heating target temperature (drying temperature minus compensation). When the sensor temperature reaches the adjusted target, the controller stops heating. This feedback loop, combined with the pre-calculated compensation, ensures the actual drum temperature stays close to the desired drying temperature without exceeding it, preventing clothes damage while keeping control logic relatively simple.

AI summary
A temperature control method and apparatus for a clothes dryer, a clothes dryer, a storage medium, an electronic device and a computer program product are provided, where an instruction for drying clothes is received, an inside-drum heater is controlled to start heating until an inside-drum temperature measurement value obtained from a current measurement of an inside-drum temperature sensor reaches a first preheating temperature value preset, then the inside-drum heater is controlled to stop heating, and the clothes dryer is controlled to execute a drying control procedure according to a preset drying temperature value, where the first preheating temperature value is lower than the drying temperature value. Through setting of the first preheating temperature value, a working state of the heater of the clothes dryer is controlled.
