Dish washer and washing method using the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwashers require complex configurations and high manufacturing costs to generate high-pressure water currents for effective washing, leading to inefficiencies and risks for users, such as dermatitis from prolonged water exposure.
Innovation Solution
A dish washer design featuring an open-top inner washing tub with perforations, surrounded by an outer tub and rotated by a motor, uses centrifugal force to detach food residues without high-pressure water, with dedicated utensils and partition plates made of cushioning materials to prevent collisions and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-pressure water current is used to wash dishes, then washing effectiveness is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent replaces the high-pressure water current mechanical system with a centrifugal force system. The washing tub rotates to generate centrifugal force that detaches food residues from dishes, eliminating the need for complex high-pressure water generation equipment while achieving effective washing.
Solution Approach 2:
The patent changes the washing parameter from high-pressure water current to centrifugal force generated by rotation. By rotating the washing tub at appropriate speeds, the centrifugal force effectively removes food residues without requiring complex high-pressure water systems.
2Reliability
If high-pressure water current is used to wash dishes, then washing effectiveness is improved, but manufacturing cost increases
Solution Approach 1:
The patent replaces the high-pressure water current mechanical system with a centrifugal force system. The washing tub rotates to generate centrifugal force that detaches food residues from dishes, eliminating the need for complex high-pressure water generation equipment while achieving effective washing.
Solution Approach 2:
The patent uses simple, inexpensive components such as a rotating washing tub and partition plates made of cushioning material. These components are easier and cheaper to manufacture compared to high-pressure water generation systems, reducing overall manufacturing cost.
3Productivity
If dishes are washed by hand continuously, then washing is performed, but risk of dermatitis increases
Solution Approach 1:
The patent implements an automatic washing system where the washing tub rotates to generate centrifugal force that washes dishes automatically. Users only need to load and unload dishes, minimizing prolonged contact with water and detergent, thereby reducing dermatitis risk while maintaining washing capability.
4Productivity
If water and detergent are used continuously for hand washing, then dishes are washed, but water and detergent are wasted
Solution Approach 1:
The patent implements an automatic washing system where the washing tub rotates to generate centrifugal force that washes dishes automatically. Users only need to load and unload dishes, minimizing prolonged contact with water and detergent, thereby reducing dermatitis risk while maintaining washing capability.
Solution Approach 2:
The patent uses centrifugal force generated by continuous rotation of the washing tub to efficiently remove food residues. This continuous action allows for effective washing with optimized water and detergent usage, reducing waste compared to continuous hand washing.

AI summary
Disclosed herein are a dish washer and a washing method using the dish washer. As an inner washing tub is rotated in a state where a dish or a cooking utensil is accommodated in a receiving space such that a food side thereof faces an outer circumference of an inner washing tub, food residues are detached from the dish or the cooking utensil by a centrifugal force and thus the dish or the cooking utensil is efficiently washed. The configuration for generating a high-pressure water current is not required, so that it is possible to produce products at low cost, and the configuration is relatively simple, so that it is possible to produce products having various sizes. Furthermore, one of dishes and cooking utensils is accommodated in each receiving space, and each of the dishes and cooking utensils is surrounded by an inner washing tub and a partition plate made of a cushioning material, so that there is no collision even if the inner washing tub is rotated, thus allowing the dishes and the cooking utensils to be effectively washed without damaging the dishes and the cooking utensils.
