Water draining structure of dehumidifier and dehumidifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dehumidifiers with pumps connected to pipes face risks of water leaking and increased drainage pressure, complicating installation and maintenance, and existing solutions like fireproof panels only address overheating and do not eliminate the risk of water leakage.
Innovation Solution
A water draining mechanism where a DC diaphragm type pump is directly connected to a water receiving tray on the dehumidifier, eliminating the need for connecting pipes, with the pump mounted vertically to reduce vibration and enhance safety, and using sealing rings for secure sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pump is connected to pipes for draining water, then drainage function is achieved, but risk of water leaking increases
Solution Approach 1:
The patent extracts and eliminates the pipe connection component from the system by implementing direct integration between the pump and water tank. The pump body is directly mounted to the water tank outlet without any intermediate piping, thereby removing the source of potential water leakage while maintaining the drainage function.
2Reliability
If pump is connected to pipes for draining water, then drainage function is achieved, but drainage pressure increases
Solution Approach 1:
The patent removes the pipe connection that was adding pressure resistance to the system. By eliminating the pipes and their connections, the drainage path is shortened and resistance is reduced, allowing the pump to operate with lower pressure requirements while maintaining effective drainage.
3Reliability
If pump and pipes are installed with connecting structure, then drainage function is achieved, but operation during installation and maintenance becomes inconvenient
Solution Approach 1:
The patent merges the pump and water tank into a single integrated assembly where the pump is directly mounted to the water tank outlet. This integration eliminates separate pipe connections, making the unit easier to install as a single component and simpler to maintain since no separate piping needs to be disconnected or repaired.
4Stress or pressure
If electromagnetic pump with high-voltage is used to meet drainage lift, then drainage capability is improved, but power consumption increases
Solution Approach 1:
The patent changes the electrical parameter from high-voltage to low-voltage (3V-37V range, preferably 12V) while compensating for the reduced voltage by optimizing the pump's mechanical design. The direct integration with the water tank reduces system resistance, allowing the low-voltage pump to achieve the required drainage lift without excessive power consumption.
5Reliability
If electromagnetic pump is used, then drainage function is achieved, but risk of pump catching fire due to heating up increases
Solution Approach 1:
The patent replaces the electromagnetic pump with a diaphragm pump that has no electrical components inside the pump body itself. The only electrical component is the external control valve, which can be easily replaced if needed. This substitution eliminates the fire hazard associated with electromagnetic pumps while maintaining effective drainage control.

Function Achieved in This Case
This configuration reduces the risk of water leaking, maximizes drainage capacity, and simplifies installation and maintenance by eliminating pipe-related pressure losses and overheating risks, while ensuring efficient drainage over long distances without noise or vibration issues.
Implementation Method 1
pump is a DC diaphragm type pump driven by a 3V-37V power source
Implementation Method 2
a pump used for draining is provided on the bottom of the outside of the water receiving tray, and the pump being directly connected with the water receiving tray
Implementation Method 3
using sealing rings for secure sealing
Implementation Method 4
the pump (31) is mounted vertically at the bottom of the water receiving tray... the vertical installation of pump can mitigate vibrating during the operation of pump

AI summary
A dehumidifier has a water receiving tray receiving condensed water of the dehumidifier. The water receiving tray comprises a water tank outlet, a main water outlet arranged outside the casing of the dehumidifier as a whole, the main water outlet being arranged opposite the water tank outlet; a pump used for draining is provided on the bottom of the outside of the water receiving tray, the pump being directly connected with the water receiving tray, eliminating the need of providing a pipe to connect with the dehumidifier pump, therefore reducing the risk of leaking. By connecting the pump with the water receiving tray directly, the pressure loss due to the connection of pipe is eliminated; the drainage capacity of the pump is utilized fully. Without installing or detaching additional pipes during installment or maintenance, operation is easier.
