Laundry maching having a drying function
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laundry machines with drying functions often fail to automatically clean lint filters, leading to accumulation of lint and reduced efficiency.
Innovation Solution
The filter is placed on the circumferential surface of the tub, where it can be cleaned by airflow from the rotating drum, and optionally assisted by water from the tub, ensuring effective lint removal and filter cleaning during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If the filter is placed in the drying duct to remove lint, then the lint filtering function is improved, but the filter requires manual cleaning and lint accumulates on the duct
Solution Approach 1:
The filter cleaning function is achieved through self-service by utilizing the existing rotational airflow within the dryer tub. The drum rotation creates airflow that automatically removes lint from the filter surface, eliminating the need for manual intervention and enabling continuous operation without maintenance停机
Solution Approach 2:
The filter is extracted from its traditional position within the drying duct and repositioned to be exposed into the tub. This extraction allows the filter to be accessed by the rotational airflow generated by drum rotation, enabling automatic cleaning while maintaining its lint filtering function
2Ease of operation
If the filter is exposed into the tub to enable automatic cleaning, then the ease of operation is improved, but the filter placement complexity increases
Solution Approach 1:
The filter structure is merged with the drying duct system, where the filter serves dual purposes: filtering lint from the drying air while being positioned to receive cleaning airflow from drum rotation. This integration reduces the need for separate cleaning mechanisms and simplifies the overall structure
Solution Approach 2:
The rotational airflow generated by the drum serves multiple functions: it dries the laundry and simultaneously cleans the filter. This multi-functionality eliminates the need for dedicated filter cleaning mechanisms, reducing device complexity while achieving automatic cleaning
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution ensures automatic cleaning of lint filters, preventing lint accumulation and maintaining the machine's efficiency by utilizing airflow and water to remove lint from the filter, enhancing the drying process.
Implementation Method 1
the filter can be cleaned by airflow caused by rotation of the drum. If a rotational speed of the drum is great, air velocity of the rotational airflow becomes strong enough to clean the filter.
Implementation Method 2
In case of a dehydrating stroke or cycle, water drops are spouted out from wet laundry through a through hole of the drum. The lint may be wetted in a way that the water drops is in contact with the filter. If the dehydrating stroke is carried out, the rotational speed of the drum is high and the water drops may approach to the filter
