Dishwasher Spray Distributor for Long-Lasting Odor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dishwashers face challenges in providing long-lasting and rapid elimination of bad smells within the washing chamber, as conventional deodorants lose efficiency over time and do not offer a permanent solution.
Innovation Solution
A dishwasher equipped with a spray distributor system that includes a pressurized vessel containing a deodorant or chemical substance, which is atomized and released into the washing chamber via a spray head activated by an actuator, either manually or through a control unit at the end of the washing cycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional deodorant tablets are used in the dishwasher, then bad smells are temporarily suppressed, but the deodorant efficiency decreases over time and cannot provide long-lasting effect
Solution Approach 1:
The deodorant is applied dynamically through a spray device that releases the deodorant substance on demand rather than relying on passive, gradual release from tablets. The spray device can be activated at specific moments (e.g., end of washing cycle) to refresh the deodorant effect, ensuring consistent performance over time.
Solution Approach 2:
The deodorant is transformed from a solid tablet form to a sprayable form (liquid, aerosol, or foam) that can be evenly distributed throughout the washing chamber. This parameter change in physical state enables more effective and uniform coverage, extending the duration and reliability of the deodorant effect.
2Object-affected harmful factors
If deodorant components are added to dishwasher detergent, then bad smells are eliminated during washing, but the effect is not permanent and cannot prevent smells after washing
Solution Approach 1:
The spray device applies deodorant substance as a preliminary action after the washing cycle completes, preparing the washing chamber environment for odor prevention. This timing ensures that the deodorant is applied when the chamber is ready to be sealed, maximizing the long-lasting effect.
Solution Approach 2:
The system maintains continuous odor protection by combining detergent deodorant components during washing with post-wash spray application. This continuous action ensures uninterrupted hygiene protection throughout the entire dishwasher operation cycle.
3Productivity
If a spray device is introduced to distribute deodorant, then rapid and efficient odor elimination is achieved, but the device complexity increases
Solution Approach 1:
The spray device is designed to serve multiple functions: distributing deodorant substance, creating aerosol/foam patterns for even coverage, and potentially integrating with existing dishwasher spray arm systems. This multi-functionality achieves rapid deodorant distribution without proportionally increasing overall system complexity.
Solution Approach 2:
A pressurized vessel acts as an intermediary component that stores and delivers the deodorant substance to the spray head. This mediator simplifies the overall system by consolidating storage, pressurization, and delivery functions in a single integrated component rather than requiring multiple separate systems.
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
Effectively eliminates bad smells within the washing chamber for a prolonged duration by ensuring timely and efficient distribution of deodorant or hygiene-enhancing substances, enhancing the overall hygiene and odor control.
Implementation Method 1
the container of the spray distributor is in the form of a pressurized vessel which is assembled to the spray head
Implementation Method 2
the pressurized vessel essentially comprises a deodorant substance which can be atomized
