Washer Drum Water Guide with Anti-Vortex Filtration Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing laundry treating apparatus experiences vortex formation in the guide portion, leading to inefficient water circulation and reduced filtration effectiveness due to varying water flow rates and shapes, which impede the water's entry into the path portion and deteriorate the filter's performance.
Innovation Solution
Incorporation of an anti-vortex member with guide ribs and a partition portion in the guide portion to prevent vortex formation, ensuring a stable water flow rate and effective circulation from the drum's lower portion to the upper portion, and enhancing the filtration process by maintaining a high flow rate through the filter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water enters the guide portion slanted or curved due to rotation of the water flow formation portion, then water circulation is achieved, but vortex is generated on the inner wall of the guide portion
Solution Approach 1:
The guide portion acts as an intermediary component between the water flow formation portion and the path portion. It includes an inlet portion that receives water from the water flow formation portion and an outlet portion that supplies water to the path portion, mediating the water flow transition and preventing vortex formation through its specific structural design
Solution Approach 2:
The guide portion changes the flow parameters of water by providing a transition path that converts the rotational water flow from the water flow formation portion into a more uniform flow suitable for the path portion, thereby preventing vortex formation while maintaining circulation efficiency
2Ease of operation
If the guide portion is attached to the outside of the drum, then water delivery is achieved, but the path area changes rapidly causing vortex
Solution Approach 1:
The guide portion is segmented into distinct functional areas: an inlet portion that receives water, a guide body that directs water flow, and an outlet portion that supplies water to the path portion. This segmentation allows each part to optimize its function and prevent vortex formation through controlled flow transitions
3Productivity
If water flow rate varies between center and inner wall of guide portion, then water circulation occurs, but vortex is generated reducing filtration effectiveness
Solution Approach 1:
The guide portion is designed with local quality variations to optimize water flow distribution. The inlet portion and outlet portion have different structural characteristics that locally adjust flow rate and direction, ensuring uniform water distribution to the path portion and preventing vortex formation that would compromise filtration effectiveness
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
The anti-vortex member effectively inhibits vortex formation, ensuring consistent water flow and improved filtration efficiency by maintaining a high flow rate and preventing water loss, thereby enhancing the overall performance of the laundry treating apparatus.
Implementation Method 1
the guide portion includes an anti-vortex member for preventing vortex of the water passing through the guide portion
Implementation Method 2
a water flow formation portion rotatably provided inside the drum, partially discharging the water inside the drum to the path portion during rotation
Implementation Method 3
a filter for filtering the water entering the path portion
