Dish Basket Guide Ribs for Mixed Dish Placement and Water Splashing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwashers face challenges in efficiently washing and drying dishes due to the design of dish baskets, which can lead to inadequate water splashing and poor usability, particularly when accommodating dishes of varying shapes and sizes, resulting in decreased washing efficiency and increased confusion for users.
Innovation Solution
A dish basket with setting sections divided by dish type, featuring support portions for underside placement and guide-shaped portions that imitate the sectional shapes of dishes, allowing intuitive placement and stable positioning of different kinds of dishes, enhancing usability and washing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dish basket uses a simple lattice structure for accommodating dishes, then the device complexity is reduced and manufacturing is easier, but the usability deteriorates because users cannot intuitively recognize placement orientations and washing efficiency decreases due to inadequate water splashing
Solution Approach 1:
The patent applies the copying principle by creating guide-shaped portions that imitate the sectional shapes of dishes. These guide portions are formed by injecting resin into molds having dish-shaped cavities, producing replica shapes that guide dish placement without requiring complex structural modifications to the entire dish basket
Solution Approach 2:
The patent applies local quality by adding guide-shaped portions only in specific setting sections where dishes need guidance, rather than redesigning the entire dish basket. The guide portions are selectively provided in resin-filled sections where improvement is needed, while maintaining the simple lattice structure in other areas
2Adaptability or versatility
If the dish basket accommodates multiple types of dishes in the same space, then the adaptability is improved, but the manufacturing precision deteriorates because it becomes difficult to ensure proper water splashing for all dish types simultaneously
Solution Approach 1:
The patent applies segmentation by dividing the dish basket into multiple setting sections, with each section dedicated to specific types of dishes. This segmentation allows each section to be optimized for its specific dish type with appropriate guide-shaped portions, ensuring proper water splashing for each category while maintaining overall versatility
Solution Approach 2:
The patent uses copying to create guide-shaped portions that replicate dish cross-sections. By injecting resin into dish-shaped molds, the guide portions accurately copy the geometry of target dishes, ensuring that multiple dish types can be accommodated with precise positioning and adequate water exposure
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 enables efficient placement and washing of various dishes, ensuring proper water splashing and improved drying efficiency by allowing users to intuitively recognize placement orientations, thus enhancing the overall usability and washing performance of the dishwasher.
Implementation Method 1
heater 8 is energized at about the same time with the start of washing pump 5 and heats the washing water in the washing step
Implementation Method 2
Washing pump 5 is mounted in communication with drain port 4, and driven by a motor. Washing pump 5 thus circulates the washing water inside washing tub 2 by spraying it from washing nozzle 7
Implementation Method 3
blower fan 13 for taking fresh air into washing tub 2

AI summary
A dishwasher includes a housing case, a washing tub disposed in the housing case, and a dish basket disposed in the washing tub for receiving dishes. The dish basket has setting sections (29) that are divided according to kinds of the dishes. The setting sections (29) include support portions (32) for supporting the dishes from underside, and ring-shaped ribs (35) serving as guide-shaped portions that imitate a sectional shape or an outline of the dishes. A support plane (W1) including the support portions (32) on one plane, and a guide-shaped plane (W2) including the guide-shaped portions on another plane are disposed at different positions. This configuration facilitates recognition of kinds and orientations of dishes to be placed, and accommodates dishes of different kinds in one area, hence providing the dishwasher of excellent usability.
