Side-Wall Middle Nozzle Layout for Larger Dishwasher Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwashers have limited capacity for loading larger dishes due to the placement of spray nozzles between racks, which restricts the size of items that can be washed and may compromise washing performance.
Innovation Solution
The dishwasher design includes a middle nozzle positioned between upper and lower racks on the side walls of the washing tub, allowing for the loading of larger items and optimizing water spray direction to maintain effective cleaning performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If spray nozzles are provided between the racks, then washing water can be sprayed effectively, but the size of dishes loaded to the rack is limited
Solution Approach 1:
The spray nozzle is relocated from a horizontal position between racks to a vertical position on the side wall of the washing tub. This dimensional change allows the nozzle to spray washing water downward onto dishes on the lower rack without interfering with dish loading capacity, while still maintaining effective washing coverage through optimized spray angle and position
2Volume of moving object
If spray nozzles are positioned between racks, then washing coverage is achieved, but larger dishes cannot be loaded
Solution Approach 1:
The spray nozzle is extracted from its conventional position between the racks and relocated to the side wall of the washing tub. This extraction removes the spatial conflict between the nozzle and large dishes, allowing maximum rack loading volume while the nozzle continues to perform its washing function from the new location

AI summary
A capable of efficiently disposing nozzles spraying washing water is provided. A dishwasher includes a washing tub, an upper rack, a lower rack and a middle nozzle. The washing tub forms a space in which dishes are washed. The upper rack has the dishes loaded thereto, being provided inside the washing tub. The lower rack is provided below the upper rack, being provided inside the washing tub. The middle nozzle sprays washing water toward the upper and lower racks, being provided on side walls of the washing tub.
