Solution Overview
Problem
Combined washing and drying machines have low drying performance due to low condensation efficiency, requiring manual clothing retrieval and occupying separate spaces for washing and drying machines.
Innovation Solution
A combined washing and drying machine design featuring a roller, condenser, drying duct, water inlet, and drainage system, where hot and humid air is cycled through a condenser with heat exchange, enhancing drying efficiency by distributing water outlet holes for improved heat exchange and using a drying impeller with arc-shaped vanes for increased air pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a combined washing and drying machine uses a simple condenser design, then the device complexity is reduced, but the condensation efficiency and drying performance become insufficient
Solution Approach 1:
The condenser is divided into multiple condensing plates (first condensing plate, second condensing plate, etc.) arranged in sequence, with each plate having independent flow guide surfaces and heat exchange portions. This segmentation increases the total heat exchange area and improves condensation efficiency while maintaining a modular structure that doesn't excessively increase complexity
Solution Approach 2:
The patent introduces a multi-dimensional water distribution system using bar-shaped containers with water outlet holes arranged in specific patterns (first water outlet holes, second water outlet holes at different positions). This spatial arrangement optimizes water flow distribution across the condensing plates, enhancing heat exchange efficiency without requiring a fundamentally complex structure
2Device complexity
If water outlet holes are concentrated in one location, then the water inlet structure is simplified, but the heat exchange efficiency is reduced
Solution Approach 1:
The bar-shaped container is designed with different water outlet hole configurations at different locations: first water outlet holes at a first position and second water outlet holes at a second position. This local differentiation ensures optimal water distribution to different areas of the condensing plates, maximizing heat exchange efficiency at each location while using a relatively simple overall structure
Solution Approach 2:
The patent uses multiple bar-shaped containers (first bar-shaped container, second bar-shaped container) that are substantially identical in structure but positioned at different locations. This copying approach maintains structural simplicity through standardization while achieving comprehensive water distribution across multiple condensing plates through spatial replication

AI summary
A combined washing and drying machine is disclosed, including a roller, a condenser, a drying duct, a water inlet device and a drainage device. Hot and humid air inlet of the condenser is connected with the roller, dry air outlet of the condenser is connected with air inlet of the drying duct, and air outlet of the drying duct is connected with the roller to form a cycle wind path. The condenser inputs condensed water through the water inlet device, and discharges the condensed water after heat exchange through the drainage device, and a plurality of water outlet holes are distributed in the water inlet device. The combined washing and drying machine is capable of cleaning clothing and drying clothing, thereby avoiding the need of manually and repeatedly accessing the clothing, and it is thus very convenient.
