Support for washing machine with automatic leveling function and washing machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machines require manual leveling, which is inconvenient and prone to instability, leading to vibration and noise issues due to the need for manual adjustment and potential support failure, especially with heavy machines on uneven surfaces.
Innovation Solution
A support system with automatic leveling function using a hydraulic medium that circulates between supports to adjust their height, ensuring the washing machine remains level without manual intervention, utilizing a regulating mechanism and flexible body assembly within a sheath to accommodate the hydraulic medium and prevent rotational movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual leveling regulation is used, then the washing machine can be leveled, but user operation is inconvenient and time-consuming
Solution Approach 1:
The patent implements automatic leveling through a hydraulic system where the washing machine self-adjusts its level using the weight distribution and hydraulic pressure differential. The system eliminates manual intervention by using the machine's own weight and the hydraulic medium to automatically regulate the support heights, achieving self-service leveling functionality.
Solution Approach 2:
The patent replaces the traditional manual mechanical adjustment system with a hydraulic automatic regulation system. Instead of requiring users to manually rotate lead screws and adjust nut gaskets, the system uses hydraulic pressure transmitted through a flexible body to automatically adjust the support heights based on the washing machine's weight distribution and level requirements.
2Reliability
If manual leveling is performed, then the washing machine can be stabilized, but supporting failure occurs during long-term use due to vibration
Solution Approach 1:
The patent employs a hydraulic system where a hydraulic medium is enclosed in a flexible body assembly that connects the supports. The hydraulic pressure transmitted through this medium provides continuous, smooth adjustment and maintains stable support heights, preventing the loosening and vibration-induced failure that occurs with manual mechanical adjustments during long-term use.
Solution Approach 2:
The patent introduces dynamic automatic adjustment capability through the hydraulic system, allowing the leveling supports to continuously adapt to vibration and weight changes during washing machine operation. The flexible body assembly with hydraulic medium enables real-time height regulation, maintaining stability despite operational vibrations that would cause manual mechanical systems to fail.
3Object-affected harmful factors
If the washing machine is not horizontal, then great vibration is caused during spin-drying, but automatic leveling requires hydraulic system complexity
Solution Approach 1:
The patent integrates multiple functions into the hydraulic leveling system: it provides automatic height adjustment, continuous stability maintenance during operation, and vibration mitigation. The same hydraulic medium and flexible body assembly that enable automatic leveling also provide smooth pressure transmission that prevents vibration, achieving multiple benefits through a unified system rather than separate components.
Solution Approach 2:
The patent uses a flexible body assembly to enclose the hydraulic medium, allowing the system to accommodate pressure changes and movement while maintaining hydraulic connectivity between supports. This flexible enclosure enables the hydraulic system to absorb vibrations and maintain stable operation without requiring complex rigid structural components, reducing overall system complexity while effectively mitigating harmful vibrations.

Function Achieved in This Case
The automatic leveling system reduces vibration and noise, enhances user comfort, and extends the service life of the washing machine by maintaining stability and accuracy in leveling without manual effort.
Implementation Method 1
a hydraulic medium, provided inside the supports for washing machine, circulates inside the supports for washing machine and/or between the supports for washing machine and levels the supports
Implementation Method 2
The telescopic end expands and contracts under an action of the hydraulic medium and drives the regulating mechanism to move axially for automatic leveling

AI summary
A support for washing machine with automatic leveling function comprises a sheath; a regulating mechanism arranged inside the sheath in an axial movable manner, whose circumferential rotation is limited by the sheath; and a flexible body inside the regulating mechanism for accommodating a hydraulic medium. The flexible body comprises a telescopic end which acts on the regulating mechanism, the telescopic end expands and contracts under an action of the hydraulic medium and drives the regulating mechanism to move axially for automatic leveling. Based on the hydraulic principle, the support can perform adaptive regulation automatically by means of the fluidity of the hydraulic medium of different pressures. Moreover, the structures of the regulating mechanism and the sheath are designed to avoid that the automatic leveling for washing machine is influenced by the regulating mechanism's rotation in inside the sheath. Thus, the automatic leveling effect is ensured.
