Integrated Bubble Generator Pump for Higher Washer Bubble Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines with bubble generators face a reduction in washing water speed due to passage resistance, resulting in a decrease in the amount of air inhaled and subsequently generated bubbles, which affects the effectiveness of bubble generation for reducing friction between laundry.
Innovation Solution
The washing machine incorporates a bubble generation pump with an ejector unit having a tubular shape and a nozzle with a reduced inner diameter, along with an air guide pipe to supply air directly to the nozzle, minimizing speed reduction and increasing bubble generation by enhancing air inhalation and mixing with washing water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If washing water is transmitted from the bubble generation pump to the ejector through a connection pipe, then the bubble generator can generate bubbles, but the speed of washing water is reduced due to passage resistance
Solution Approach 1:
The ejector unit is integrated directly into the bubble generation pump housing, eliminating the connection pipe between the pump and ejector. This merging of components removes the passage resistance that caused speed reduction, allowing the washing water to maintain its velocity while still enabling effective air mixing and bubble generation in the tub.
2Quantity of substance
If the washing water speed is reduced, then the passage resistance is reduced, but the amount of air inhaled into the ejector is reduced
Solution Approach 1:
By integrating the ejector unit directly into the pump housing, the washing water maintains its high speed from the impeller directly into the ejector mixing chamber. This eliminates the speed-reducing connection pipe, ensuring that the high-velocity water flow can effectively draw in and mix with sufficient air volume to generate abundant bubbles.
3Object-affected harmful factors
If the amount of generated bubbles is reduced, then the friction between laundry is increased, but the washing effectiveness is reduced
Solution Approach 1:
The integrated design of the ejector unit within the pump housing eliminates passage resistance, maintaining washing water speed and maximizing air inhalation. This results in increased bubble generation, which provides a cushioning effect that reduces friction between laundry items during the washing process, thereby protecting garments from damage.

Function Achieved in This Case
This configuration effectively generates more bubbles, reducing friction between laundry items by maintaining washing water speed and increasing the amount of air mixed with the water, thereby improving the washing process.
Implementation Method 1
an ejector, which inhales air and mixes the air with the washing water supplied from the bubble generation pump to generate bubbles
Implementation Method 2
an impeller rotated by the bubble generation motor and causing the washing water to flow

AI summary
Disclosed is a washing machine having a bubble generator to wash laundry using bubbles. The washing machine includes a tub to contain washing water; and a bubble generator generating bubbles and supplying the bubbles to the tub, the bubble generator including a bubble generation pump allowing the washing water to flow therethrough and an ejector unit formed at one side thereof to mix air with the washing water. The washing machine minimizes a reduction of the speed of the washing water due to a passage resistance, and thus increases an amount of generated bubbles.
