Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washer-dryer machines face challenges with high costs due to dedicated refrigeration devices and low dehumidification and drying efficiency when directly spraying condensed water on hot and humid air flows.
Innovation Solution
A condensing module is designed with a housing, condenser, air inlet, air outlet, and a spoiler to enhance air flow contact with the condenser, along with a cold source inlet and outlet for efficient condensation and dehumidification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated refrigerating device (evaporator and condenser) is used for condensing hot and humid air flow, then condensation effect is improved, but cost increases
Solution Approach 1:
The patent combines the condensation function with the existing drum structure by forming the condenser on the inner wall of the drum, eliminating the need for a separate dedicated refrigerating device. The drum serves dual purposes: drying clothes and condensing humid air, thereby reducing system complexity and cost while maintaining condensation effectiveness.
Solution Approach 2:
The drum is designed to perform multiple functions: it acts as both the drying chamber and the condenser. The inner wall of the drum serves as the condensation surface, allowing the same component to handle both mechanical drying and thermal condensation tasks, thus avoiding additional cost-intensive equipment.
2Productivity
If condensed water is directly sprayed to hot and humid air flow, then dehumidification is attempted, but moisture remains in air flow and drying efficiency is low
Solution Approach 1:
The patent replaces the mechanical spray system with a thermal condensation system. Instead of mechanically spraying condensed water back into the air flow, the system uses the cold inner wall of the drum to thermally condense humid air, allowing gravity to naturally drain the condensed water through the outlet at the bottom, thereby improving dehumidification effectiveness.
Solution Approach 2:
The patent utilizes phase transition of water from vapor to liquid through thermal condensation on the cold drum surface. The humid air contacts the cooled inner wall of the drum, causing water vapor to condense into liquid water that then drains out, achieving effective dehumidification without re-spraying moisture back into the air.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution improves condensation efficiency, reduces moisture retention in air flows, and lowers operational costs by optimizing the interaction between air flows and the condenser, resulting in enhanced dehumidification and drying performance.
Implementation Method 1
a condenser disposed in the housing for condensing high-temperature humid air flow entering the housing
Implementation Method 2
a spoiler disposed on an inner wall of the housing, where an air flow passage is formed by the inner wall of the housing, the spoiler, and the condenser so that the high-temperature humid air flow is in sufficient contact with the condenser

AI summary
A condensation module, a drying module and an all-in-one washer dryer. The condensation module comprises: a casing (1) and a condenser (3) arranged in the casing (1); an air inlet (11) arranged in one side of the casing (1); an air outlet (12) arranged in the opposite side of the casing (1); and a flow disturbing component (22) arranged on the inner wall of the casing (1). An airflow passage is formed among the inner wall of the casing (1), the flow disturbing component (22) and the condenser (3), so as to enable high-temperature wet airflows to be in full contact with the condenser (3). In the condensation module, the flow disturbing component (22) arranged on the inner wall of the casing (1) can prevent airflows from directly flowing towards the air outlet (12) along the inner wall of the casing (1), and the airflow passage is formed among the inner wall of the casing (1), the flow disturbing component (22) and the condenser (3), so as to enable the high-temperature wet airflows to be in full contact with the condenser (3), thereby improving condensation and dehumidification efficiency.
