Dishwasher Ozone Dissolution Using Circulation Pump Vortex Effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dishwashers using ozone washing struggle with the effective dissolvability of ozone gas in washing water, which affects washing performance and requires higher detergent and water consumption, as well as increased energy use due to higher temperature requirements.
Innovation Solution
The ozone generator is positioned before the circulation pump in the suction line, utilizing the pump's vortex effect to increase ozone gas dissolution in the water, with a variable speed motor and controlled rotational speed to optimize ozone intake, and a hose configuration that prevents water leakage and supports the ozone generator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If ozone gas is dissolved in washing water using conventional methods, then washing process can be performed, but dissolvability of ozone in washing water is insufficient
Solution Approach 1:
The ozone generator is positioned in the suction line before the circulation pump, so ozone gas is introduced into the water flow path in advance. The water flow created by the circulation pump then naturally draws and dissolves the ozone gas, eliminating the need for separate dissolution equipment and ensuring adequate ozone dissolution before washing begins.
Solution Approach 2:
The invention utilizes the hydraulic flow generated by the circulation pump to create a vacuum effect that draws ozone gas into the water stream. The moving water flow acts as a carrier that absorbs and transports ozone gas, converting mechanical hydraulic energy into effective gas dissolution without requiring additional pneumatic or mechanical dissolution devices.
2Productivity
If higher temperature is used for washing, then washing effectiveness improves, but energy consumption increases
Solution Approach 1:
The invention introduces ozone gas, a strong oxidant, into the washing water to enhance the chemical cleaning action. Ozone provides powerful disinfectant and soil removal effects that allow effective washing at lower temperatures, thereby reducing energy consumption while maintaining or improving washing effectiveness through enhanced oxidative cleaning mechanisms.
3Productivity
If more detergent and water are used, then washing performance improves, but resource consumption increases
Solution Approach 1:
Ozone gas serves as a powerful cleaning agent that replaces or supplements conventional detergents. The disinfectant and soil removal properties of ozone allow effective washing with reduced detergent quantities, while the ozone-washed water can be recirculated, reducing overall water consumption.
Solution Approach 2:
The circulation pump continuously circulates the ozonized washing water through the system, maintaining constant contact between the ozone-treated water and the dishes. This continuous circulation ensures thorough cleaning action without requiring excessive water volumes, as the same water is repeatedly used and refreshed with ozone.
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 configuration enhances ozone dissolvability in the washing water, improving washing performance while reducing detergent and water consumption and energy use by allowing lower temperature operations.
Implementation Method 1
the suction of the ozone gas generated in the ozone generator into water is provided with the vacuum effect created by the circulation pump
Implementation Method 2
the amount of ozone gas dissolved in the washing water is increased by means of vortexes formed in the chamber of the circulation pump due to the effect of the motor
Implementation Method 3
ozone gas (O3) having disinfectant and soil removal effects is used for increasing the effectiveness of the washing process
