Washing and drying all-in-one machine and control method therefor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machines and clothing dryers require separate control, leading to long overall time consumption and poor user experience due to the need for preheating the dryer after washing is complete.
Innovation Solution
A washing-drying integrated machine with a co-working function that links the washing and drying programs, allowing the dryer to preheat based on the remaining time of the washing program, thereby reducing overall cycle time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dryer is preheated after washing is complete, then the drying function is ensured, but the overall time consumption increases
Solution Approach 1:
The dryer is preheated in advance during the washing process rather than waiting until washing is complete. The control unit detects the remaining time of the washing program and initiates dryer preheating when the remaining time is within a preset threshold, performing the preheating action preliminarily to reduce overall cycle time while ensuring the drying function is ready when needed
Solution Approach 2:
The control unit continuously detects the remaining running time of the washing program and uses this feedback information to determine the optimal timing for initiating dryer preheating. When the detected remaining time is less than or equal to a preset threshold, the control unit activates the dryer preheating function, creating a closed-loop control system that optimizes the timing between washing and drying operations
2Ease of operation
If the washing machine and clothing dryer are used separately, then each device can be controlled independently, but the user experience deteriorates due to manual coordination
Solution Approach 1:
The washing machine and clothing dryer are integrated into a single washing-drying integrated machine with a unified control unit. This merging allows the system to automatically coordinate washing and drying operations, eliminating the need for manual intervention while maintaining the functional capabilities of both devices. The control unit manages both washing program execution and dryer preheating/drying operations as an integrated system
Solution Approach 2:
The integrated machine performs automatic coordination between washing and drying functions without requiring user intervention. The control unit autonomously detects washing program status, determines optimal preheating timing, and manages the transition to drying operations, allowing the system to serve itself and eliminating the need for manual task switching between separate appliances

Function Achieved in This Case
The integrated machine reduces the overall washing-drying time by preheating the dryer during the washing process, enhancing user experience and meeting intelligentization needs.
Implementation Method 1
heating the air in the drying cylinder to a predetermined temperature
Implementation Method 2
the fan is used to convey hot air into the drying cylinder

AI summary
A washing and drying all-in-one machine and a control method therefor. The control method includes: when a washing and drying all-in-one machine enters a washing-drying linkage mode, measuring a remaining time of a washing program, and determining whether the remaining time is within a preset first time threshold value; and if so, a clothes dryer matching a drying program corresponding to the clothes and performing preheating, and after waiting for the washing program to end, the washed clothes being placed in the clothes dryer for drying. By the washing and drying all-in-one machine and the control method therefor, according to the remaining time of the washing program, the clothes dryer is started in advance to execute a drying program and is preheated, such that the entire washing-drying time consumption of the clothes is shortened, thereby improving the user experience, and meeting the increasing intelligent requirements of users.
