Dehumidifier Filter Net Slot Design for Tool-Free Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dehumidifiers require complex disassembly and assembly processes for cleaning or replacing the filter net, affecting user experience due to the need to disassemble the machine body shell.
Innovation Solution
A dehumidifier design featuring a filter net slot beside the air inlet allows for easy insertion and removal of the filter net without disassembling the outer shell, along with a machine body that extends relative to the water tank for improved air discharge and stability, reducing the overall center of gravity and occupied space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter net is installed inside the machine body shell, then the filter net can effectively filter the air entering the dehumidifier, but the disassembly and assembly process becomes complicated requiring shell disassembly
Solution Approach 1:
The filter net is segmented from the machine body shell through the design of a detachable filter net slot. The filter net can be independently removed from the slot without disassembling the shell, dividing the filtration component from the housing structure. This allows the filter net to be accessed, removed, cleaned, or replaced independently while maintaining its effective positioning during operation.
2Stability of the object's composition
If the machine body is fixed inside the water tank, then the dehumidifier has stable structure, but the air outlet position is low limiting air discharge efficiency
Solution Approach 1:
The machine body is designed with dynamic positioning capability relative to the water tank through a movable mounting structure. The machine body can be extended upward from the water tank during operation to position the air outlet at a higher elevation for improved air discharge efficiency, while being accommodated within the water tank when idle to maintain stability and lower center of gravity. This dynamic adjustment resolves the contradiction between fixed stability and operational productivity.
3Productivity
If the machine body is extended out from the water tank during operation, then the air outlet is at higher position for better air distribution, but the occupied space increases
Solution Approach 1:
The machine body transitions between extended and retracted positions dynamically based on operational state. During operation, it extends to provide optimal air outlet height for efficient air distribution throughout the room. When idle or for storage, it retracts into the water tank, minimizing the occupied footprint. This dynamic configuration allows the system to optimize air distribution efficiency when needed while reducing space occupation during non-operation.
4Ease of operation
If the filter net slot is designed for easy access, then the filter net can be removed without disassembling the shell, but the structural integrity of the machine body may be compromised
Solution Approach 1:
The filter net slot is designed as a segmented, self-contained opening with integrated mounting features. The slot includes positioning structures and securing mechanisms that allow the filter net to be independently installed and removed without compromising the overall shell structure. This segmentation enables easy filter access while maintaining the structural integrity of the machine body through properly engineered slot boundaries and reinforcement.

AI summary
A dehumidifier comprising: a water tank with a mounting port facing upward, a machine body including an air inlet and a filter net slot beside the air inlet, and a filter net removably inserted in the filter net slot and covering the air inlet. The machine body is configured to be in one of a plurality of states including an idle state in which the machine body is at least partially accommodated in the water tank through the mounting port and a working state in which the machine body is extended out relative to the water tank through the mounting port.
