Dishwasher and base assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The overflow structure of conventional dishwashers is prone to clogging due to pollutants entering the overflow channel, making it difficult to detect and clean pollutants in a timely manner, which leads to odor issues.
Innovation Solution
The base component of the dishwasher includes an overflow cover with an overflow chamber and a water inlet plate featuring filter holes, preventing pollutants from entering the overflow channel and allowing for easy visual inspection and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the overflow channel is directly exposed without a filter structure, then the overflow function is simple and the structure is compact, but pollutants easily enter the overflow channel causing clogging
Solution Approach 1:
The overflow cover body is divided into multiple functional regions: an overflow port for water discharge, a mounting portion for installation, and a water inlet plate with filter holes for pollution prevention. This segmentation allows each component to perform its specific function while maintaining overall system reliability.
Solution Approach 2:
The water inlet plate with filter holes acts as an intermediary component between the overflow channel and the external environment. It mediates the flow of water while blocking pollutants, preventing direct entry of contaminants into the overflow channel without completely obstructing water flow.
2Ease of operation
If the overflow cover is sealed and not removable, then the structure is compact and simple, but it is difficult to visually detect and clean pollutants in a timely manner
Solution Approach 1:
The overflow cover body is designed with a removable mounting portion that allows it to be detached from the base component. This dynamic design enables users to access the inlet surface for visual inspection and cleaning when needed, while maintaining a compact sealed structure during normal operation.
Solution Approach 2:
The filter holes in the water inlet plate are pre-designed to trap pollutants before they enter the overflow channel. This preliminary filtration action reduces the frequency and amount of cleaning required, allowing users to perform maintenance only when necessary while maintaining hygiene.
3Reliability
If filter holes are added to the water inlet plate, then pollutants are trapped and overflow channel clogging is prevented, but the water inlet plate structure becomes more complex
Solution Approach 1:
The water inlet plate is designed with multiple filter holes that create a porous filtration structure. This allows the plate to trap pollutants while maintaining water flow capability, achieving reliable anti-clogging performance through a relatively simple perforated plate design rather than complex filtration mechanisms.
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 overflow channel clogging and facilitates timely cleaning of pollutants, maintaining cleanliness and reducing odors.
Implementation Method 1
the water inlet plate is arranged with a plurality of filter holes. Through the water inlet plate, pollutants can be trapped to prevent the pollutants from directly entering the overflow channel

AI summary
A connection structure used with a dishwasher is provided. The connection structure has a base, an outer plate located at an outside of the base at an interval, and a top support mechanism connected to the outside of the base. The top support mechanism has one or more top support tubes sequentially stacked in a direction from the base to the outer plate. Each top support tube has first, second, third, and fourth top support plates, each having elastic recovery property. An opening direction of a first spacing groove formed by the first and second support plates and an opening direction of a second spacing groove formed by the third and fourth support plates are opposite to each other.
