Washing Machine Descaling Rod Layout for Inner and Outer Tank Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional descaling devices for washing machines are unable to effectively clean the outer wall of the inner tank, requiring additional perforations that complicate user assembly and limit cleaning effectiveness.
Innovation Solution
A descaling device with a rotating and extendable/retractable descaling rod, connected to a main body within the inner tank, which includes a connecting rod and descaling rod configuration, allowing for simultaneous cleaning of both the inner and outer tank walls through a series of hinges and adjustable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the descaling brush bristles are lengthened to reach the outer wall of the inner tank, then the cleaning coverage is improved, but the structural complexity increases and assembly becomes more difficult
Solution Approach 1:
The descaling device is divided into multiple independent components: a main body with water inlet, a connecting rod, and a descaling rod with bristles. This segmentation allows each component to perform its specific function independently, achieving comprehensive cleaning coverage without requiring a single complex structure.
Solution Approach 2:
The descaling rod is designed to be extendable and retractable relative to the main body through the connecting rod mechanism. This dynamic structure allows the descaling rod to reach different positions (inner wall, outer wall, and bottom of the tank) during rotation, maximizing cleaning coverage while maintaining simple assembly.
2Reliability
If additional perforations are added to the inner tank for installing descaling brushes, then the cleaning effectiveness is improved, but the assembly complexity for users increases
Solution Approach 1:
The main body of the descaling device is designed to be lashed by water to rotate, which simultaneously drives the connecting rod and descaling rod to rotate. This multi-functional design allows a single device to clean the inner wall, outer wall, and bottom of the tank without requiring multiple perforations or separate installation points.
Solution Approach 2:
The descaling device utilizes the water flow from the water inlet as its driving force. The water pressure automatically rotates the main body and connected components, eliminating the need for external power sources or complex installation mechanisms. Users only need to install the device through existing structures, simplifying assembly.
3Device complexity
If the descaling brush is fixed to the inner tank, then the structure is simplified, but the ability to clean the outer wall of the inner tank is lost
Solution Approach 1:
The connecting rod connects the main body to the descaling rod, allowing the descaling rod to extend outward and rotate independently. This dynamic connection enables the descaling rod to reach the outer wall of the inner tank while maintaining a simple overall structure, achieving both structural simplicity and comprehensive cleaning area.
Solution Approach 2:
The descaling rod is nested within the connecting rod structure, which itself is connected to the main body. This nested arrangement allows the descaling rod to be compact when retracted and extended when needed, achieving comprehensive cleaning coverage without increasing overall structural complexity.
