Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drying machines lack the ability to efficiently utilize waste heat and provide uniform drying for both large and small capacity laundry loads, often requiring separate units and compromising on energy efficiency and user convenience.
Innovation Solution
A dual-type drying machine with a main drying unit of large capacity and an auxiliary drying unit of small capacity, integrated into a single cabinet, allowing independent operation and uniform air flow control, with waste heat from the main unit transferred to the auxiliary unit for enhanced energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single drying machine is used for both large and small capacity laundry, then device complexity is reduced, but drying uniformity and energy efficiency deteriorate
Solution Approach 1:
The drying machine is divided into two independent drying units: a first drying unit with a first drum and a second drying unit with a second drum. Each unit can operate independently with its own air circulation system, allowing optimized drying conditions for different laundry capacities while maintaining drying uniformity.
Solution Approach 2:
Each drying unit has its own dedicated air circulation system, heater, and control mechanisms tailored to its specific capacity requirements. The first drying unit is configured for large capacity laundry while the second is optimized for small capacity laundry, ensuring each operates at optimal efficiency.
2Manufacturing precision
If separate drying machines are used for large and small capacity laundry, then drying uniformity is improved, but device complexity and space requirement increase
Solution Approach 1:
Two independent drying units are merged into a single integrated drying machine with a common cabinet structure, control system, and power supply. This allows the benefits of dedicated drying units for different capacities while avoiding the complexity and space requirements of completely separate machines.
Solution Approach 2:
The drying machine serves multiple functions by accommodating both large capacity laundry in the first unit and small capacity laundry in the second unit simultaneously or independently, making the device adaptable to various drying needs within a single apparatus.
3Loss of energy
If waste heat is not utilized, then device complexity is reduced, but energy efficiency deteriorates
Solution Approach 1:
The waste heat generated by the heater in the first drying unit is captured and transferred to the second drying unit through a heat transfer system. This converts the harmful waste heat into a useful resource, pre-heating the air for the second unit and reducing overall energy consumption.
Solution Approach 2:
Instead of discarding the waste heat from the first drying unit's air circulation system, the invention recovers this thermal energy through heat exchangers and applies it to the second drying unit, thereby improving overall energy efficiency of the system.

Function Achieved in This Case
Enables efficient and uniform drying of laundry across varying capacities, improves energy efficiency by utilizing waste heat, and enhances user convenience through independent operation and intuitive design.
Implementation Method 1
The moisture of the high-temperature high-humidity air is condensed by the condenser 40
Implementation Method 2
the air is heated by a heater 60, i.e., an electric heater. The heated air flows into the drum 10
Implementation Method 3
The condenser 40 enables the high-temperature high-humidity air to be heat-exchanged with external low-temperature air
