Auxiliary Washer Door Assembly With Guided Water Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines lack a dedicated space for hand washing delicate items and have issues with water pressure distribution, leading to inefficient washing and potential water scattering.
Innovation Solution
A washing machine with an auxiliary washing unit that forms a separate hand-washing space and an adjustable water supply mechanism, allowing for independent hand washing and precise control of water pressure through a water pressure regulation device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If washing water is supplied at high pressure, then water supply speed is improved, but water scatters around the periphery instead of reaching the desired point
Solution Approach 1:
A guide structure is introduced as an intermediary component between the water supply source and the target washing area. This guide structure channels and directs the water flow, ensuring that even under pressure, the water reaches the intended location accurately rather than scattering. The guide acts as a mediator that maintains both the speed advantage of pressurized water and the precision of targeted delivery.
2Adaptability or versatility
If a separate auxiliary washing space is added for hand washing, then washing versatility is improved, but device complexity increases
Solution Approach 1:
The auxiliary washing unit is merged with the door assembly of the washing machine. By integrating the hand washing function into the existing door structure, the patent achieves multi-functionality without proportionally increasing overall system complexity. The door serves dual purposes: as an access closure for the main washing chamber and as a housing for the auxiliary washing unit, thereby combining multiple functions into a single structural element.
Solution Approach 2:
The door assembly is designed to serve multiple functions: it acts as the closure for the main washing drum, provides structural support, and houses the auxiliary washing unit for hand-washing delicate items. This multi-functional design allows the washing machine to handle both regular drum washing and delicate hand-washing tasks, enhancing versatility while utilizing existing structural components.
3Area of stationary object
If an auxiliary washing unit is integrated into the door, then space utilization is improved, but ease of operation deteriorates due to multiple handles
Solution Approach 1:
The door handle and the auxiliary washing unit are merged into a single integrated assembly. The handle serves dual purposes: it operates the main door closure and simultaneously serves as the operational interface for the auxiliary washing unit. This integration eliminates the need for separate handles, reducing the number of operational elements while maintaining full functionality.
Solution Approach 2:
The handle is designed as a multi-functional component that performs both door opening/closing operations and auxiliary washing unit operations. By making the handle universal for both functions, the design simplifies the user interface, reducing the cognitive and physical burden of operating multiple separate controls while maximizing space utilization within the door structure.

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.
