Appliance Drainage Control for Floor Drain Overflow Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Household electrical appliances, such as washing machines, often experience water overflow from their drain pipes into floor drains, leading to cleanliness and safety issues due to excessive water discharge during drainage cycles.
Innovation Solution
A method and apparatus that determine when a floor drain is at risk of overflow and adjust the water discharge rate from the appliance's drain pipe by reducing the amount of water per unit time, using sensors and control modules to monitor the drain pipe and floor drain conditions, and adjust the water pump or valve accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the equipment discharges water at a high rate during drainage, then the drainage efficiency is improved, but the floor drain may overflow causing cleanliness and safety issues
Solution Approach 1:
The patent applies dynamics by making the water discharge rate adjustable rather than fixed. The control module dynamically modifies the operating parameters of the water pump or drainage valve based on real-time feedback from the detection module, allowing the system to adapt the discharge rate to current floor drain conditions and prevent overflow while maintaining efficient drainage when possible
Solution Approach 2:
The patent implements feedback control through a detection module that continuously monitors floor drain conditions (such as water level or flow rate) and feeds this information back to the control module. This closed-loop feedback system enables the equipment to automatically adjust the discharge rate to prevent overflow while optimizing drainage efficiency
2Loss of time
If the equipment discharges water quickly to complete drainage faster, then the drainage time is reduced, but the floor drain capacity may be exceeded
Solution Approach 1:
The system dynamically adjusts the water discharge rate based on real-time detection of floor drain conditions. When the floor drain can handle high flow, the system maintains high discharge rates to minimize drainage time. When the floor drain approaches capacity, the system automatically reduces the discharge rate to prevent overflow, thus optimizing the balance between drainage speed and floor drain capacity
Solution Approach 2:
The patent changes the operational parameters of the drainage system (such as pump speed or valve opening degree) based on detected conditions. By dynamically modifying these parameters, the system can discharge water as quickly as possible when conditions permit, while preventing overflow when the floor drain capacity is approached, thereby optimizing both drainage time and safety

AI summary
Disclosed is a method, apparatus and storage medium for controlling drainage of equipment. The method includes: determining that the equipment is in a drain state; detecting whether a floor drain connected to a drain pipe of the equipment is at risk of drainage overflow or a drainage overflow occurs; and when it is detected that the floor drain is at risk of drainage overflow or the drainage overflow occurs, reducing an amount of water discharging from the drain pipe per unit time.
