Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing drying machines, particularly circulation-type and blower-type models, face challenges in efficiently discharging condensed water, leading to potential heater reliability issues and increased production costs due to different component structures required for heater-type and heat pump-type machines, despite sharing similar external dimensions.
Innovation Solution
A common base design for drying machines that incorporates a condensation duct mount with a consistent shape and size, allowing for the use of the same base in both heater-type and heat pump-type machines, along with a condensed water-discharging structure that prevents water from flowing into the drum or heater, using a combination of outer and inner ribs to direct water into a sump efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different bases are used for heater-type and heat pump-type drying machines to accommodate different heating and condensing structures, then the machines can be optimized for their respective types, but the number of components to be managed increases and production costs increase
Solution Approach 1:
The base is designed with a universal structure that can accommodate both heater-type and heat pump-type drying machines. The condensation duct mount is configured with a standardized shape and size that works with different condenser types, allowing the same base to serve multiple functions and support different machine variants without requiring separate base designs.
2Adaptability or versatility
If different bases are manufactured and managed for heater-type and heat pump-type drying machines, then each machine type can have optimized components, but manufacturing and after-sales servicing become difficult
Solution Approach 1:
The base design incorporates a standardized condensation duct mount that can accommodate both heater-type and heat pump-type machines, creating a universal platform that simplifies manufacturing processes and after-sales servicing while maintaining adaptability to different machine types through selective mounting of appropriate components.
Solution Approach 2:
The base is segmented into modular components, with the condensation duct mount being a separate, standardized module that can be selectively configured for different machine types. This segmentation allows for easier manufacturing, assembly, and maintenance while preserving versatility.
3Device complexity
If condensed water is not efficiently discharged from the air circulation unit, then the structure is simpler, but condensed water may be reheated or flow into the drum or heating unit causing reliability deterioration
Solution Approach 1:
The base includes a pre-configured condensation duct mount and water discharge pathway that is designed in advance to efficiently channel condensed water away from the heating unit and drum. The ribs are pre-formed to direct water flow into the sump, preventing potential reliability issues before they can occur during operation.

AI summary
A drying machine is provided that may include a drum configured to receive items to be dried, an air circulating device that circulates air through the drum, a motor that drives a drying fan for air circulation, a condenser that condenses moisture in circulating air introduced from the drum, a heater that heats the circulating air introduced from the condenser, and a base, which is provided under the drum to support the drum and which may form a lower portion of the drying machine. The air circulating device may include a condensation duct, which may change in structure in order to accommodate different types of condensers based on how the respective condensers perform heat exchange. The base may include a condensation duct mount having a consistent shape and size to accommodate the condensation duct regardless of a shape of the condensation duct.
