Dual-Passage Dehumidifier Airflow Layout for Cooler Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dehumidifiers often compromise on space utilization and user convenience due to separate fan units and elevated discharge temperatures, which can be inconvenient for users.
Innovation Solution
A dehumidifier design incorporating a compressor, condenser, and evaporator with dual fans that enhance air flow rate through the condenser, allowing for reduced condensing temperature and improved space utilization, while also directing dehumidified and non-dehumidified air in different directions for enhanced convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a separate fan is used together with the dehumidifier to increase air circulation and dehumidifying efficiency, then moisture removal efficiency is improved, but utilization of room space deteriorates and handling convenience deteriorates
Solution Approach 1:
The patent merges the fan function with the dehumidifier by integrating a fan motor into the dehumidifier's air outlet structure. The fan is positioned to directly blow discharged air back into the room, combining dehumidification and air circulation functions into a single integrated unit, thereby improving space utilization and handling convenience while maintaining enhanced moisture removal efficiency.
2Productivity
If the fan is used together with the dehumidifier to increase air circulation, then dehumidifying efficiency is improved, but utilization of room space deteriorates
Solution Approach 1:
The fan is integrated within the dehumidifier's air outlet assembly, merging two functions into one compact unit. This eliminates the need for separate fan placement in the room, thereby improving space utilization while achieving enhanced dehumidifying efficiency through increased air circulation.
3Temperature
If high temperature air is discharged from the dehumidifier after passing through the condenser, then heat exchange efficiency is improved, but user convenience deteriorates
Solution Approach 1:
The patent introduces a second air inlet and a bypass passage as intermediary elements. Ambient air drawn through the second air inlet serves as a cooling medium that mixes with the hot discharged air from the condenser in the bypass passage, thereby reducing the temperature of air entering the room and improving user comfort while maintaining heat exchange efficiency.
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 dual fan system increases air flow rate through the condenser, reduces condensing temperature, and improves user convenience by allowing for more efficient air discharge and reduced power consumption, effectively addressing the limitations of single fan systems.
Implementation Method 1
a first passage for drawing air through the air inlet, and discharging the air through the air outlet after passed through the evaporator, the condenser, a first fan, and a second fan in succession
Implementation Method 2
a first passage for drawing air through the air inlet, and discharging the air through the air outlet after passed through the evaporator, the condenser
Implementation Method 3
having a compressor, a condenser, an expansion device, and an evaporator through which refrigerant is circulated

AI summary
Disclosed is a dehumidifier, having a compressor, a condenser, an expansion device, and an evaporator through which refrigerant is circulated, including a casing having an air inlet and an air outlet formed therein, a first passage for drawing air through the air inlet, and discharging the air through the air outlet after passed through the evaporator, the condenser, a first fan, and a second fan in succession, and a second passage for drawing the air through the air inlet and discharging the air through the air outlet after passed through the second fan, thereby, not only increasing the flow rate of the air passing through the condenser enabling to reduce a condensing temperature, but also discharging the air passed through the condenser mixed with the air drawn into the second passage enabling to drop the temperature of the air being discharged to the air outlet, permitting to resolve user's inconvenience.
