Balance Ring Water Outlet for Low-Power Washer Dehydration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines require excessive water and detergent due to water level differences between inner and outer tubs, leading to inefficiencies and waste, and high-power motors are needed for effective water discharge, which is not environmentally friendly.
Innovation Solution
A washing machine design featuring a water outlet passage between a balance ring and washing tub, allowing for efficient water discharge through high-speed rotation during dehydration, reducing the need for dehydration holes and minimizing water consumption while using a low-power electric motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a high-power electric motor is employed to discharge water during dehydration, then water discharge efficiency is improved, but energy consumption and noise increase
Solution Approach 1:
The patent extracts the water discharge function from the motor-driven centrifugal force system and relocates it to the balance ring structure. The balance ring with its specific mass distribution and water outlet passages passively directs water discharge during dehydration without requiring high motor power, thus maintaining productivity while reducing energy consumption.
Solution Approach 2:
The balance ring structure performs the water discharge function automatically during dehydration through its own rotational dynamics and gravity-driven water flow paths. The system uses the dehydration rotation itself to activate water discharge through the balance ring passages, eliminating the need for additional high-power motor input.
2Ease of operation
If water level in inner tub and outer tub are the same during washing, then washing coverage is improved, but water consumption increases
Solution Approach 1:
The patent implements a dynamic water level difference mechanism where the inner tub can rotate independently within the outer tub. During washing, the inner tub rotates to create centrifugal force that distributes water evenly across clothes, achieving good washing coverage without requiring the outer tub to be filled to the same level, thus reducing overall water consumption.
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 design achieves dynamic water saving by retaining most washing water within the tub for washing and discharging it efficiently, reducing water and detergent usage, and lowering energy consumption while maintaining effective dehydration.
Implementation Method 1
the high-speed rotation of the washing tub in the dehydration process will discharge the water in the washing tub out of the washing tub via the water outlet passage
