Dishwasher and base assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwasher overflow structures are prone to clogging and difficult to clean, as pollutants like rice grains and minced meat easily enter the overflow channel and adhere to the inlet surface of the overflow cover, making timely cleaning challenging.
Innovation Solution
A base component with an overflow cover featuring an overflow chamber and a water inlet plate equipped with filter holes, which prevents pollutants from entering the overflow channel and allows for easy visual inspection and removal of attached pollutants, thereby preventing clogging and odor issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the overflow cover is not removed, then the structure remains intact and functional, but it is impossible to visually detect pollutants adhering to the inlet surface
Solution Approach 1:
The patent applies transparency principles by making the overflow cover body transparent or translucent, allowing visual detection of pollutants adhering to the inlet surface without removing the cover. This enables users to observe the inlet surface condition while maintaining the overflow cover's structural integrity and functionality.
2Device complexity
If pollutants are allowed to enter the overflow channel directly, then the structure remains simple, but clogging occurs easily
Solution Approach 1:
The patent segments the overflow structure into distinct functional components: an overflow chamber, an inlet surface, and an overflow channel. The overflow chamber acts as a separation zone where pollutants are trapped before water enters the overflow channel, effectively dividing the flow path to prevent clogging while maintaining overall structural simplicity.
Solution Approach 2:
The overflow chamber serves as an intermediary structure between the inlet surface and the overflow channel. It mediates the water flow by allowing pollutants to be retained in the chamber while directing clean water through the overflow channel, thus preventing clogging without adding complex filtering mechanisms.
3Reliability
If pollutants adhere to the inlet surface of the overflow cover, then the overflow function is maintained, but timely cleaning becomes difficult
Solution Approach 1:
By making the overflow cover body transparent or translucent, the patent enables visual inspection of the inlet surface for adhered pollutants. Users can detect when cleaning is needed without disassembling the overflow cover, maintaining the overflow function while significantly improving cleaning convenience through timely detection.
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 effectively prevents clogging and facilitates timely cleaning of the overflow channel by trapping pollutants and allowing for intuitive observation and removal of attached debris, enhancing the maintenance efficiency of the dishwasher.
Implementation Method 1
the water water inlet plate is arranged with a plurality of filter holes. Through the water water inlet plate, pollutants can be trapped to prevent the pollutants from directly entering the overflow channel
