Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dryer designs suffer from water leakage and reduced heat preservation due to the hollow structure communication between the two-device installation cavity and the drainage channel, affecting drying efficiency and heat exchange efficiency.
Innovation Solution
An air duct shell with an integrally formed liquid drainage channel, utilizing a partition plate to seal the drainage groove and guide grooves to prevent water leakage and ensure effective drainage, while maintaining heat exchange efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a hollow structure is used to communicate the two-device installation cavity with the drainage channel, then the structure is simple and easy to manufacture, but water leakage and air leakage occur affecting drying efficiency
Solution Approach 1:
The patent merges the drainage groove and the sealing structure into an integrated unit. The sealing ring is embedded directly within the drainage groove structure, creating a unified component that combines drainage functionality with leak prevention. This integration eliminates the need for separate sealing mechanisms while ensuring reliable water-tight communication between the installation cavity and drainage channel.
2Device complexity
If a hollow structure is used to communicate the two-device installation cavity with the drainage channel, then the structure is simple, but heat preservation is reduced affecting drying efficiency
Solution Approach 1:
The patent introduces a sealing ring as an intermediary element within the drainage groove. This sealing ring not only prevents water and air leakage but also serves as a thermal barrier that reduces heat loss through the drainage channel communication path. The intermediary structure thus addresses both leakage prevention and heat preservation requirements simultaneously.
3Productivity
If the evaporator condenses humid air, then drying efficiency is improved, but condensed water accumulation occurs affecting heat exchange efficiency
Solution Approach 1:
The patent extracts the condensed water removal function from the heat exchange system by providing a dedicated drainage groove that communicates the installation cavity with the drainage channel. This separate drainage pathway efficiently removes condensed water from the evaporator area, preventing water accumulation that would otherwise interfere with heat exchange efficiency while maintaining high drying efficiency.
