Venturi Dispensing Assembly for Washing Agent Dissolution and Foaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing agent dispensing devices in washing machines suffer from poor dissolving efficiency, leading to agglomeration and increased risk of pipeline blockage, as well as inadequate foaming and cleaning effects.
Innovation Solution
A dispensing assembly with a main pipe housing that incorporates a gas inlet port and a suction port, allowing washing agent and gas to enter through independent channels, utilizing the Venturi effect to enhance dissolving and foaming by introducing gas during the washing agent's flow, thereby improving cleaning efficiency and reducing blockage risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If washing agent is dispensed through conventional channels, then dispensing function is achieved, but dissolving efficiency is poor leading to agglomeration and pipeline blockage risk
Solution Approach 1:
The dispensing system is segmented into separate channels: a liquid channel for water flow and a gas channel for air intake. The gas channel includes a gas inlet port positioned upstream of the liquid outlet port, allowing gas and liquid to travel through separate pathways before mixing at the dispensing point. This segmentation prevents washing agent agglomeration by ensuring proper mixing while eliminating pipeline blockage risks associated with conventional single-channel designs.
2Productivity
If washing agent is dispensed without gas introduction, then device complexity is reduced, but foaming effect and cleaning efficiency are insufficient
Solution Approach 1:
The gas channel structure serves multiple functions: it introduces air for foaming enhancement, creates a pressure differential to control liquid flow rate, and prevents washing agent agglomeration through proper mixing. By integrating these functions into a single gas channel component with strategically positioned inlet and outlet ports, the system achieves superior cleaning efficiency without proportionally increasing device complexity.
3Productivity
If gas inlet port is positioned downstream, then structure is simpler, but washing agent cannot be sufficiently dissolved and foaming effect is poor
Solution Approach 1:
The gas inlet port is positioned upstream of the liquid outlet port in the gas channel, allowing gas to be introduced into the liquid flow before the washing agent is fully dispensed. This preliminary gas introduction creates bubbles that enhance mixing and dissolution of the washing agent in advance, maximizing foaming effect and cleaning efficiency when the mixture reaches the dispensing point.
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 solution ensures thorough dissolution of washing agents, enhances foaming and cleaning effects, and reduces the risk of agglomeration and pipeline blockage by ensuring the washing agent and gas are mixed uniformly from the outset, even without additional flushing steps.
Implementation Method 1
The main pipe housing is a Venturi pipe and includes a first pipe section, a second pipe section, and a third pipe section that connected in sequence, a flow area of the second pipe section being smaller than a flow area of the first pipe section and smaller than a flow area of the third pipe section
Implementation Method 2
Through the disturbance of the gas, the washing agent can be sufficiently dissolved in the water flow, which improves the foaming effect of the washing agent and the cleaning effect
