Dual-Function Purification Dehumidifier with Separate Air Outlets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dehumidifiers on the market primarily have a low utilization rate as they only serve dehumidification functions, leaving them idle most of the time and lacking air purification capabilities.
Innovation Solution
A purification dehumidifier is designed with both dehumidification and air purification functions, featuring a housing with separate air inlets, dehumidified air outlets, and purified air outlets, incorporating a dehumidifier assembly and a purifier assembly, along with a cross-flow fan and air door assembly for efficient airflow management and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dehumidifier only has dehumidification function, then device structure is simple, but utilization rate is low and air purification capability is lacking
Solution Approach 1:
The patent combines dehumidification and air purification functions into a single device. The dehumidifier assembly and purifier assembly are integrated within the same housing, sharing common components like the fan and control system, thereby achieving functional versatility without proportionally increasing device complexity
Solution Approach 2:
The device is designed to perform multiple functions: dehumidification mode, air purification mode, and combined mode. The housing includes separate outlets for dehumidified air and purified air, allowing the device to adapt to different usage scenarios and improve utilization rate
2Adaptability or versatility
If separate outlets for dehumidified air and purified air are provided, then functional flexibility is improved, but housing structure becomes more complex
Solution Approach 1:
The housing is segmented into distinct air outlet regions: a dehumidified air outlet and a purified air outlet. This segmentation allows independent control and optimization of each function while maintaining a unified overall structure. The air duct is also segmented to guide different air streams separately
3Ease of operation
If air door assembly with multiple swing blades is used, then airflow control precision is improved, but device complexity increases
Solution Approach 1:
The air door assembly uses swing blades that can rotate dynamically to adjust airflow distribution. The swing blades are connected to a driving member that enables precise angular control, allowing the device to flexibly direct air flow between different outlets based on operational requirements
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 enables simultaneous dehumidification and air purification, improving the utilization rate and effectiveness of the device by allowing for separate or combined operation of dehumidification and purification modes, enhancing air quality and efficiency.
Implementation Method 1
a fan arranged in the air duct to introduce an airflow into the air duct from the air inlet and blow the airflow in the air duct out from the dehumidified air outlet and the purified air outlet
Implementation Method 2
a dehumidifier assembly, arranged in the air duct and corresponding to the dehumidified air outlet
Implementation Method 3
a purifier assembly, arranged in the air duct and corresponding to the purified air outlet
