Dishwasher Washing Ball Case with Drainage Holes and Bonding Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing ball cases for dishwashers lack drainage holes, leading to wet washing balls, which reduces their efficiency, and the thermal bonding process often results in bonding defects due to uneven plate positioning during the bonding process.
Innovation Solution
A case body with through holes in the outer side portion for complete drainage of washing water and the use of reference grooves and fixing pins to ensure uniform bonding of the top and bottom plates without movement during thermal bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the case body is made without through holes to maintain structural integrity, then the case structure remains simple and strong, but washing water accumulates at the lower portion causing washing balls to become wet and reducing washing efficiency
Solution Approach 1:
The case body is segmented with through holes formed at the lower side, dividing the case into regions that allow water to pass through. This segmentation enables complete drainage while maintaining overall structural integrity, allowing washing balls to stay dry and efficient without major structural redesign
2Ease of manufacture
If the top plate and bottom plate are thermally bonded without additional fixing to simplify the manufacturing process, then the manufacturing process is simpler, but the plates move during bonding causing bonding defects
Solution Approach 1:
Fixing pins are inserted into through holes before the thermal bonding process begins, preliminarily securing the top and bottom plates in correct alignment. This preliminary fixing prevents plate movement during bonding, ensuring manufacturing precision while maintaining process simplicity
Solution Approach 2:
Fixing pins act as intermediary elements between the top and bottom plates during thermal bonding. These pins temporarily hold the plates in fixed positions, enabling precise bonding without requiring complex positioning mechanisms, thus improving both ease of manufacture and bonding precision

Function Achieved in This Case
Maintains washing balls in a dry state for maximum efficiency and prevents bonding defects by ensuring uniform plate positioning during thermal bonding.
Implementation Method 1
the dishes are washed through the antibacterial and purifying action and the like by the far-infrared radiation from the washing balls
Implementation Method 2
a hot plate is inserted between the top plate and the bottom plate so as to melt bonding portions thereof

AI summary
The present invention relates to a washing ball case for a dishwasher, used to wash dishes by washing balls of a ceramic material and washing water without using any detergents and, more particularly, to a washing ball case for a dishwasher, wherein a case body (100) is formed by thermally bonding a top plate (10) and a bottom plate (20) and has through holes (120) formed in an outer side portion thereof so as to completely drain the washing water at the time of washing dishes such that the washing balls can be maintained in a dried state through the complete draining of the washing water and the washing efficiency of the washing balls can be maximized in next dish-washing, and through holes (120) and reference grooves (130) are provided to the outer portions of the top plate (10) and the bottom plate (20) such that, at the time of the thermal bonding, the top plate (10) and the bottom plate (20) can be bonded to each other at uniform positions in a fixed state without movement by the through holes (120) and the reference grooves (130) so as to prevent the conventional bonding defects.
