Drum Spray Nozzle Direction Control for Faster Washing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines do not effectively improve washing performance by spraying washing water onto laundry, leading to suboptimal cleaning results.
Innovation Solution
A washing machine design featuring a cabinet with a drum and a spray nozzle system that sprays washing water into the drum, with a direction changing unit that adjusts the spraying direction based on the drum's rotation, ensuring accurate and efficient water distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spray nozzle system is added to spray washing water into the drum, then washing performance is improved, but device complexity increases
Solution Approach 1:
The spray nozzle is integrated within the drum structure, with the spray nozzle disposed inside the cabinet to spray washing water into the drum. The spray nozzle system is nested within the existing drum and cabinet structure, avoiding additional external components and minimizing device complexity while improving washing performance through direct water spraying onto the laundry
Solution Approach 2:
The spray nozzle system utilizes the existing washing water supply infrastructure of the washing machine, drawing water from the same source that supplies the drum. The system serves itself by using the machine's own water supply mechanism, eliminating the need for separate water delivery systems and reducing overall device complexity
2Productivity
If washing water is sprayed rapidly onto laundry, then washing time is reduced, but energy consumption increases
Solution Approach 1:
The spray nozzle operates in periodic cycles rather than continuously, spraying washing water onto the laundry at intervals during the wash cycle. This periodic spraying action maintains effective washing performance and reduces wash time while minimizing energy consumption by keeping the spray system inactive during non-spraying periods
Solution Approach 2:
The system adjusts spray parameters such as spray duration, spray intensity, and spray frequency to optimize the balance between washing effectiveness and energy consumption. By dynamically changing these parameters based on wash cycle requirements, the system achieves rapid washing without excessive energy use
