Rotatable Dishwasher Sprayer With Adjustable Spray Outlets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic dishwashers face inefficiencies in distributing water and cleaning agents across dishes due to fixed spray patterns, which can lead to inadequate cleaning and increased water usage.
Innovation Solution
A rotatable sprayer system with moveable valve bodies that adjust spray outlets to change spray patterns from wide-angle to focused, allowing for optimized distribution of water and cleaning agents based on the rotation of the sprayer arm, thereby enhancing cleaning effectiveness and reducing water consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed spray patterns are used in conventional dishwashers, then the spray system structure is simple, but cleaning effectiveness is inadequate and water usage increases
Solution Approach 1:
The patent applies the dynamics principle by making the spray system adjustable through moveable valve bodies that can change spray patterns from wide-angle to focused. The rotatable sprayer body with multiple spray outlets allows dynamic reconfiguration of water distribution, enabling the system to adapt to different cleaning needs and improve effectiveness while maintaining reasonable structural complexity.
2Loss of substance
If fixed spray patterns are used, then the device structure is simple, but water usage increases due to inadequate cleaning efficiency
Solution Approach 1:
The moveable valve bodies enable dynamic adjustment of spray patterns to optimize water distribution. By switching between wide-angle and focused spray modes, the system delivers water more efficiently to targeted areas, reducing overall water consumption while maintaining or improving cleaning effectiveness.
Solution Approach 2:
The patent changes the parameters of water spray distribution by allowing valve bodies to move and reposition spray outlets. This enables variation in spray angle, pressure distribution, and coverage area, optimizing water usage efficiency while ensuring thorough cleaning performance.
3Adaptability or versatility
If multiple moveable valve bodies are added to enable spray pattern adjustment, then cleaning effectiveness improves, but device complexity increases
Solution Approach 1:
The moveable valve bodies serve multiple functions: they control spray pattern adjustment, regulate water flow distribution, and enable rotation of the sprayer body. By consolidating these functions into single components, the patent reduces the need for separate mechanisms, thereby limiting the increase in device complexity while achieving high adaptability.
Solution Approach 2:
The patent merges the functions of spray control, flow regulation, and sprayer rotation into integrated moveable valve body assemblies. This consolidation reduces the number of separate components needed, managing device complexity while providing versatile spray pattern adjustment capabilities.

AI summary
A dishwasher includes a tub at least partially defining a treating chamber and a spraying system having a sprayer supplying liquid to the treating chamber. The sprayer may include a liquid passage and multiple spray outlets to emit sprays to wash the dishes, a first valve body to couple at least one of the multiple spray outlets to the liquid passage, and a second valve body to control a flow of liquid.
