Dehumidifier Drainage Control Using Timer-Based Power Device Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dehumidifiers face issues with water drainage when the device is positioned at a low location and the water needs to be drained to a higher location, often resulting in incomplete drainage due to inaccurate water level detection, leading to faulty operations.
Innovation Solution
A method and device for controlling drainage in dehumidifiers that involve detecting the compressor's operation and using a power device to drain water after a preset period, with timed control to start and stop the drainage process, eliminating the reliance on water level detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If water level detection is used to control drainage, then drainage can be triggered when water reaches a certain level, but the water level detection may be abnormal or inaccurate causing incomplete drainage
Solution Approach 1:
The patent replaces the mechanical water level detection system with a timer-based control system. Instead of relying on sensors to detect water levels, the system uses a timer to control the power device's operation duration, thereby eliminating detection accuracy issues and ensuring reliable drainage completion.
2Adaptability or versatility
If the dehumidifier is positioned at a low place and water needs to be drained to a high place, then drainage is needed, but the conventional drainage mode becomes inapplicable
Solution Approach 1:
The patent applies preliminary action by having the power device start draining water after a preset time delay following compressor shutdown. This timing ensures that drainage begins at the optimal moment, allowing water to be effectively pumped from low to high positions without requiring complex real-time adjustments.
3Reliability
If the power device operates continuously to drain water, then complete drainage can be achieved, but energy consumption increases
Solution Approach 1:
The patent implements periodic action by controlling the power device to operate for a specific duration determined by a timer, rather than running continuously. The device starts after a preset delay and stops after a predetermined operation period, achieving complete drainage while minimizing energy consumption through time-based periodic control.
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
This approach ensures consistent and complete drainage of water from the dehumidifier by using timed control of the power device, preventing issues related to abnormal water level detection and improving operational reliability.
Implementation Method 1
water is usually drained from the low place to the high place by means of power generated by a power device

AI summary
A method for controlling drainage of a dehumidifier includes the following steps. When a compressor of a dehumidifier is powered on, it is detected whether the compressor operates or not. When it is detected that the compressor stops operating, a power device of the dehumidifier is controlled to start draining water off after a first preset period. Operation period of the power device is detected. It is judged whether the operation period reaches a second preset period or not. When it is determined that the operation period reaches the second preset period, the power device is controlled to stop operating. A dehumidifier and a drainage control device thereof are also disclosed.
