Top-Load Washer Basket Structure for Higher Capacity in Compact Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines face challenges in increasing washing capacity without enlarging the machine's size, particularly in vertical axis models, making it inconvenient to load laundry due to increased height.
Innovation Solution
The washing machine design includes a spin basket with an inclined side wall and through holes for water discharge, a drain groove system, and a dual-structured cabinet with an outer and inner part for efficient water management, allowing for increased washing capacity without expanding the machine's dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the size of the spin basket is increased to increase washing capacity, then the washing capacity is improved, but the size of the cabinet and overall machine dimensions increase
Solution Approach 1:
The spin basket is nested within the tub, and the inner part is nested within the outer part of the cabinet. This nested configuration allows the spin basket to utilize the internal space efficiently without increasing the external dimensions of the cabinet, thereby increasing washing capacity while maintaining compact machine size.
Solution Approach 2:
The spin basket employs an inclined side wall design that expands in the radial direction rather than increasing height. This dimensional approach allows the spin basket to accommodate more laundry by utilizing horizontal space more effectively, increasing washing capacity without proportionally increasing the overall machine footprint.
2Quantity of substance
If the height of the washing machine is increased to increase washing capacity, then the washing capacity is improved, but it becomes inconvenient to put laundry into the machine
Solution Approach 1:
Instead of increasing machine height, the design increases the radial dimension of the spin basket through the inclined side wall. This allows the washing machine to maintain a user-friendly height while expanding washing capacity through horizontal space utilization, making it easier to load and unload laundry.
3Quantity of substance
If the size of the cabinet is increased to accommodate a larger spin basket, then the washing capacity is improved, but the space available for installation is limited
Solution Approach 1:
The nested structure of the inner part within the outer part of the cabinet allows for efficient space utilization. The spin basket is further nested within the tub, creating a compact hierarchical arrangement that maximizes washing capacity within a limited installation footprint.
Solution Approach 2:
The inclined side wall of the spin basket expands capacity in the radial direction rather than increasing vertical or horizontal footprint. This dimensional strategy allows the washing machine to accommodate more laundry without increasing the area required for installation.

AI summary
A washing machine having an improved structure which increases washing capacity without increasing the size of the washing machine. The washing machine includes a cabinet including an outer part and a cylindrical inner part connected to the outer part, a spin basket rotatably disposed in the inner part and including a bottom and a side wall extending from the bottom, a pulsator rotatably disposed in the spin basket, a motor provided under the spin basket, a clutch to selectively transmit power of the motor to the spin basket or the pulsator, a base plate to fix the clutch and the motor, and suspension members connecting the base plate to the upper portion of the cabinet. Wash water is stored within the spin basket and is not stored outside the spin basket during a washing cycle.
