Solution Overview

Problem

Existing clothing treatment apparatuses with drying functions suffer from low moisture adsorption efficiency, long drying times, and high power consumption due to inconsistent evaporator temperatures and inefficient dehumidification methods, leading to high energy consumption.

Innovation Solution

A clothing treatment apparatus with a drying module featuring a moisture adsorption-desorption member that includes a dehumidification area and a regeneration area, where the airflow path is designed to converge, ensuring stable airflow pressure and flow rate, allowing for continuous moisture adsorption and desorption, and utilizing materials like zeolite or silica gel for efficient moisture management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If an evaporator is used to heat and absorb moisture in the inner drum, then high-temperature air is obtained for drying clothes, but the overall temperature consistency of the evaporator causes decreasing moisture adsorption capacity and low drying efficiency

Engineering Contradiction:
Improvedrying efficiencyVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The drying module is divided into a first drying module housing and a second drying module housing, with the moisture adsorption-desorption member positioned between them. This segmentation allows for separate functional zones and improved airflow management, enabling the system to maintain effective moisture adsorption capacity while reducing overall power consumption through optimized thermal management.

Inventive Principle:

Solution Approach 2:

The moisture adsorption-desorption member is designed to periodically pass through different positions, creating dynamic airflow paths. This dynamic operation allows the system to adaptively manage moisture adsorption and desorption processes, maintaining high drying efficiency while optimizing energy consumption by varying the operational state of the adsorption member.
