Washing Tub Drain Valve Integration for Leak-Tight Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machines face leakage issues due to complex and difficult-to-mount drain pipes with separate valve parts, which can lead to inefficiencies and environmental concerns.
Innovation Solution
A simplified drain pipe system where the valve part is integrated with the washing tub, eliminating separate joints and using a cylindrical pipe connected via conventional flanges, with a buoyant valve that floats to close or open the drain port based on water presence, ensuring tightness and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate valve part is used in the drain pipe, then the drainage function can be achieved, but the complexity of the drain pipe increases and mounting becomes difficult
Solution Approach 1:
The valve part is integrated directly into the drain pipe as a single component, eliminating the need for separate valve assemblies and flange connections. This merging of the valve function into the pipe structure itself simplifies the overall drain pipe design and makes installation straightforward.
2Reliability
If a separate valve part is used in the drain pipe, then the drainage function can be achieved, but leakage problems occur due to multiple joints
Solution Approach 1:
The valve part is integrated directly into the drain pipe as a single component, eliminating the need for separate valve assemblies and flange connections. This merging of the valve function into the pipe structure itself simplifies the overall drain pipe design and makes installation straightforward.
3Ease of manufacture
If a complex valve part is used, then the drainage control function is achieved, but the manufacturing and assembly difficulty increases
Solution Approach 1:
The valve part is integrated directly into the drain pipe as a single component, eliminating the need for separate valve assemblies and flange connections. This merging of the valve function into the pipe structure itself simplifies the overall drain pipe design and makes installation straightforward.

Function Achieved in This Case
This design enhances the tightness and ease of mounting the drain pipe, reducing leakage risks and maintaining efficient operation by integrating the valve part with the tub, allowing for better control over the drainage process.
Implementation Method 1
a drain valve buoyant in the wash water, movably disposed inside the valve member to close the drain port when there is wash water inside the tub and the drain pump is at rest, or to open the drain port when there is no washing water inside the tub or the drain pump is operating

AI summary
The invention relates to a washing machine, comprising a wash tub (30) that is filled with wash water and that has a drain opening (38), a drain pump (40), a drain line (50) that connects the water in the wash tub (30) to the drain pump (40), a valve part (52) that is connected to the wash tub in a sealed fashion, and comprising a pipe part (54) that is connected to the drain pump for water transfer; also a drain valve (60) that can float in the wash water, said valve being disposed moveably inside the valve part in order to seal the drain opening (38) in a closed position (B) when wash water is located inside the wash tub and when the drain pump (40) is idle, or in order to open the drain opening to an opened position (A) when no wash water is located inside the wash tub or when the drain pump is operating. The valve part (52) is designed in one piece together with the wash tub (30) and the pipe part (54) is connected to an outlet connection (56) of the valve part (52).
