Dehumidifier Drain Pump with External Tank and Inlet Filter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dehumidifiers require users to carry and pour water from a bulky water tank, making it inconvenient and laborious.
Innovation Solution
A dehumidifier design featuring a water tank placed outside and below the body, equipped with a drain pump and filter, allowing water to be discharged without needing to carry the tank, and incorporating a filter to prevent impurities from entering the drain pump.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the water tank is placed inside the body, then the device structure is compact, but the water tank volume is limited and users must carry the tank for pouring
Solution Approach 1:
The device is segmented into separate functional modules: the water tank is detached from the main body and placed externally, while the drain pump remains integrated in the body. This segmentation allows the water tank to have larger capacity without increasing the footprint of the main device, and enables automated draining without manual carrying.
Solution Approach 2:
A drain pump is introduced as an intermediary device between the water tank and the drainage system. The pump automatically transfers water from the external tank to the drainage outlet, eliminating the need for users to manually carry and pour water from the tank.
2Volume of moving object
If the water tank is placed outside the body, then the water tank volume can be larger, but the connection between tank and body becomes more complex
Solution Approach 1:
The connection structure between the water tank and body is designed with universal interfaces that accommodate multiple functions: mechanical support, water tight sealing, and electrical connection for the drain pump. This multi-functional interface reduces the number of separate components needed and simplifies the overall connection system.
3Reliability
If no filter is provided at the water inlet, then the structure is simpler, but impurities can enter the drain pump causing blockages
Solution Approach 1:
A filter is installed at the water inlet of the drain pump to perform preliminary filtration of impurities before water enters the pump. This preliminary action prevents particles and debris from reaching the pump interior, avoiding blockages and maintaining reliable operation throughout the device's service life.
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 design reduces the need for users to carry the water tank for pouring, allows for a larger water tank volume to accommodate more dehumidification water, and filters impurities to prevent drain pump blockages.
Implementation Method 1
a drain pump provided at the body, wherein a water outlet end of the drain pump is connected to the drain position, a water inlet end of the drain pump is connected to the water tank
Implementation Method 2
the water inlet end of the drain pump is provided with a filter... impurities such as dust particles in the water in the water tank can be filtered
