Washing Machine Door Assembly with Pivoting Auxiliary Washing Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines lack a dedicated space for auxiliary washing and have inadequate control over washing water pressure, leading to inefficient washing and water dispersion issues.
Innovation Solution
A washing machine with an auxiliary washing unit that forms a separate washing space and a water supply device capable of adjusting water pressure, featuring a pivotable auxiliary washing unit and a water pressure regulation mechanism to manage water flow effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single washing space is provided in conventional washing machines, then the device complexity is low, but the adaptability for different washing needs (main washing and auxiliary washing) is insufficient
Solution Approach 1:
The door assembly is designed to serve multiple functions: it acts as both a closure for the main washing space and houses an auxiliary washing unit that can pivot between storage and operational positions. This allows the washing machine to perform both main washing and hand-washing functions within a single device structure, thereby improving adaptability without proportionally increasing complexity.
Solution Approach 2:
The auxiliary washing unit is designed with a pivotable connection to the door assembly, allowing it to dynamically change position between a retracted state (when not in use) and an extended operational state (when hand-washing is needed). This dynamic configuration enables the system to adapt its structure based on functional requirements, providing versatility while maintaining a compact form when the auxiliary function is not needed.
2Productivity
If high pressure washing water is supplied, then the productivity of water supply is high, but the washing water scatters around the periphery instead of discharging to the desired point
Solution Approach 1:
A water guide structure is introduced as an intermediary component between the water supply device and the auxiliary washing space. This guide structure receives high-pressure washing water and directs it along a controlled path, preventing scattering while maintaining the momentum and pressure needed for effective cleaning. The water guide acts as a mediator that preserves water supply efficiency while achieving precise water discharge to the desired location.

AI summary
Provided is a washing machine including a main body having an opening and a door assembly disposed at the opening, wherein the door assembly includes a door that opens and closes the opening and an auxiliary washing unit having an auxiliary washing space in which hand-washing can be performed, and provided to pivot about one side of the door in an inside of the door. Through this configuration, separated washing spaces can be provided and separate hand-washing can be performed. Also, pressure of washing water supplied into the washing machine can be regulated so that water supply efficiency can be improved and a flow rate of the washing water can be adjusted.
