Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machines face challenges in enhancing detergent efficacy, particularly in delicate programs like hand wash, wool, or silk, and in preventing detergent residue on textile products, as conventional methods may damage textiles or fail to fully dissolve detergent chemicals.
Innovation Solution
A washing machine with a detergent dissolving system that utilizes a jet pump, a valve, and a control unit to mix detergent and water within the pump body before releasing it into the washing environment, allowing for extended mixing times during delicate programs and lower temperatures, and incorporating a heating cycle with a heater to enhance detergent dissolving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If temperature is increased to enhance detergent dissolving, then detergent efficacy is improved, but delicate textiles may be damaged
Solution Approach 1:
The patent applies preliminary action by dissolving detergent in the detergent compartment before the main washing cycle begins. The jet pump creates water circulation that dissolves detergent powder in advance, allowing the detergent to be fully activated before contacting the laundry. This eliminates the need for high temperatures during the washing process itself, protecting delicate textiles while ensuring effective detergent dissolution.
2Manufacturing precision
If mechanical motion is increased to enhance washing performance, then washing efficacy is improved, but delicate textiles may be damaged
Solution Approach 1:
The jet pump creates water circulation and mechanical motion in the detergent compartment before the main washing cycle. This preliminary mechanical action dissolves the detergent thoroughly, allowing the detergent solution to be transferred to the drum without requiring intense mechanical agitation during the actual washing of delicate items. The detergent is pre-activated, reducing the need for harsh mechanical treatment.
3Manufacturing precision
If detergent dissolving time is extended to improve dissolution, then detergent efficacy is enhanced, but washing cycle time increases
Solution Approach 1:
The patent segments the washing process into distinct phases: a preliminary detergent dissolving phase in the detergent compartment using the jet pump, followed by the main washing phase in the drum. This segmentation allows detergent dissolution to occur in parallel with water heating and before the main wash, optimizing the use of time without extending the overall cycle duration. The jet pump's high-velocity water flow also accelerates dissolution during this phase.
Solution Approach 2:
The jet pump utilizes hydraulic principles to create high-velocity water circulation in the detergent compartment. The pump draws water from the bottom of the compartment and喷射 it upward, creating turbulence and rapid water movement that accelerates detergent dissolution. This hydraulic action provides efficient mixing and dissolution without requiring extended time, as the high-velocity water flow quickly distributes detergent throughout the water.
4Device complexity
If conventional detergent delivery is used, then device complexity is minimized, but detergent residue remains on textiles
Solution Approach 1:
The jet pump creates a hydraulic flow that continuously circulates water through the detergent compartment, ensuring complete dissolution and suspension of detergent particles. This high-velocity water circulation prevents undissolved detergent from being transferred to the drum, eliminating residue on textiles. The hydraulic action creates turbulence that keeps detergent particles suspended until fully dissolved, then directs the clear detergent solution to the main washing area.
