Dehumidifier with nesting water tank
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dehumidifiers have an unreasonable internal component distribution, leading to a non-compact structure and low space utilization, which affects dehumidification efficiency and makes them bulky for transportation and storage.
Innovation Solution
A dehumidifier design with a vertically arranged axial flow fan, evaporator, and condenser, along with a water receiving tray that divides the case into an air duct for heat exchange and a mounting cavity for components, optimizing space use and compactness, and allowing the machine body to be partially received in the water tank during idle states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional dehumidifiers use traditional component layout, then components can be easily installed, but the internal structure is not compact and space utilization is low
Solution Approach 1:
The machine body is received within the water tank when the dehumidifier is in idle state, creating a nested configuration where one component houses another. This nesting approach maximizes space utilization and reduces the overall volume occupied by the dehumidifier system during storage or transport.
Solution Approach 2:
The axial flow fan, evaporator, and condenser are arranged vertically in a side-by-side configuration, transitioning from traditional horizontal layouts to a vertical arrangement. This dimensional change optimizes space utilization within the case and improves the compactness of the internal structure.
2Volume of moving object
If components are arranged to maximize space utilization, then device volume is reduced, but internal structure complexity increases
Solution Approach 1:
The water receiving tray divides the case interior into distinct functional regions: an axial flow air duct for heat exchange and a receiving cavity for housing the machine body. This segmentation organizes components into logical groups, managing internal structure complexity while maintaining compactness.
Solution Approach 2:
The water tank serves dual functions: it stores condensed water during operation and houses the machine body during idle state. This multi-functionality reduces the need for separate storage structures, simplifying the overall internal structure while maximizing space utilization.
3Volume of moving object
If axial flow fan, evaporator, and condenser are arranged vertically, then space utilization is improved, but air flow path complexity increases
Solution Approach 1:
The water receiving tray creates a clear separation between the axial flow air duct and the receiving cavity, establishing distinct air flow paths. This segmentation ensures that air flow remains organized and efficient despite the vertical arrangement of components, managing the complexity of the air flow path.
4Ease of operation
If machine body is received in water tank during idle state, then transportation and storage are facilitated, but accessibility to components is reduced
Solution Approach 1:
The dehumidifier transitions between two states: during operation, the machine body is positioned for optimal function with full component accessibility; during idle state, the machine body is received within the water tank for compact storage. This dynamic reconfiguration allows the system to optimize for different operational requirements.
