Sink Washing Machine Drain Board Layout for Pump Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sink-type washing machines face issues with food residues entering the water pump, reducing its efficiency and service life, and require excessive water and detergent usage, making them inefficient and environmentally unfriendly.
Innovation Solution
A sink-type washing machine design featuring a recessed drain region covered by a drain board with specific dimensions and placement, isolating the water pump from the washing area and optimizing water flow to prevent residue entry and minimize water consumption, using an open water pump with an impeller and guide bracket for efficient water handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the water pump is placed in the washing region to be supplemented with water directly from the washing region, then the water pump can be supplemented with water during washing, but the supplemented water is inevitably greasy and contains food residues which influences the operating efficiency and service life of the water pump
Solution Approach 1:
The sink bottom is segmented into a washing region and a drain region separated by a drain board. The drain board with drain holes creates a physical barrier that segments the water flow path, allowing the pump to be positioned in the drain region where water is relatively cleaner, thus improving pump reliability while maintaining water supplementation functionality.
Solution Approach 2:
The drain board acts as an intermediary component between the washing region and the pump. It mediates the water flow by allowing water to pass through drain holes while filtering out food residues and grease, thus protecting the pump from direct contact with contaminated water.
2Productivity
If the entire bottom of the sink is used as the water supplementation region, then water can be supplemented to the water pump, but the larger the area of the sink bottom is, the larger the amount of water needed for washing is, and a greater amount of detergent is needed causing waste
Solution Approach 1:
The drain region is created as a localized area with different functionality from the washing region. By concentrating the water supplementation function in a specific localized area (the drain region) rather than using the entire sink bottom, the invention reduces the overall water and detergent consumption while ensuring adequate water supply to the pump.
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 effectively filters out food residues from the water pump, improves its efficiency and lifespan, reduces water and detergent usage, and enhances water feeding for better washing performance while maintaining water holding capacity.
Implementation Method 1
a water pump; the recess under the drain board forms a drain region; the water pump is disposed in the drain region for pumping the water in the drain region to above the drain board

AI summary
A sink-type washing machine comprises a case having a sink body; the sink body has a recess at least at the center of the bottom portion; a drain board having a same shape as the recess which is covered on the recess; the drain board has a plurality of drain holes; the recess under the drain board defines into a drain region; the surface of the drain board is flush with the bottom portion of the sink body around the drain board; the water pump is disposed in the drain region for pumping the water in the drain region to above the drain board. By having the water pump arranged in the drain region of the sink body, the water pump is provided with a great water replenishment effect, arrangement of a water outlet component is facilitated, and an improved spraying effect can be acquired.
