Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing drying machines face challenges in efficiently managing condensed water, which can flow into the drum or heater, leading to inefficiencies and potential damage, particularly in circulation-type and blower-type machines, increasing production costs and complicating manufacturing and maintenance due to the need for different components for heat pump-type and heater-type machines.
Innovation Solution
A common base design for drying machines is introduced, featuring a condensed water-discharging structure with a first drying duct and outer rib to prevent condensed water from flowing into the drum or heater, and a second drying duct with an inclined drain outlet to efficiently direct condensed water into a sump, reducing the complexity of managing different types of drying machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a circulation-type drying machine uses a common base design, then manufacturing complexity is reduced and production costs decrease, but condensed water may flow into the drum or heater causing inefficiency and potential damage
Solution Approach 1:
The base is divided into a first base portion and a second base portion with different structures. The first base portion includes a first flow channel that prevents condensed water from entering the drum, while the second base portion includes a second flow channel that prevents condensed water from entering the heater. This segmentation allows each portion to address specific condensed water management needs while maintaining a common base design.
Solution Approach 2:
A condensed water collection chamber is introduced as an intermediary structure between the condenser and the drum/heater. The collection chamber receives condensed water from the condenser and directs it through controlled flow channels to the drum or heater, preventing uncontrolled water flow while enabling efficient water management in the common base design.
2Reliability
If different components are used for heat pump-type and heater-type machines, then condensed water management is optimized for each type, but production costs increase and manufacturing becomes more complex
Solution Approach 1:
The common base design incorporates a multi-functional structure that can serve both heat pump-type and heater-type drying machines. The base includes configurable flow channels and collection chambers that can be adapted to different machine types through software control or simple hardware configuration, eliminating the need for completely different base designs for each machine type.
Solution Approach 2:
The base design incorporates dynamic configuration capabilities where flow channels and water discharge paths can be adjusted or switched based on the machine type. This allows the same physical base structure to optimize condensed water management for both heat pump-type and heater-type machines by changing operational parameters or simple structural adjustments.

AI summary
A drying machine may include a condensation duct for accommodating a condenser, a first drying duct connected to a rear end of the condensation duct and to a drying fan housing accommodating a drying fan, and a second drying duct connected to the drying fan housing and to a drum. The drying machine may also include a first drying duct drain outlet formed in the lower portion of the first drying duct, and an outer rib, which is provided at the side edge of the first drying duct drain outlet that is close to the drying fan housing and that extends upward, so as to prevent condensed water, introduced through the condensation duct, from flowing over the first drying duct drain outlet.
