Foot for household appliance and household appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household appliance leveling systems require manual adjustment, which is inconvenient and lacks precision, especially for heavy appliances, leading to vibration and reduced service life due to unlevel placement and vibration-induced instability.
Innovation Solution
A foot for household appliances featuring a hydraulic plate, sheath, and regulating foot with a throttling structure that uses hydraulic medium pressure changes to automatically adjust and stabilize the appliance, preventing rapid fluid flow and ensuring stable leveling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of bolt feet is used for leveling, then the washing machine can be leveled, but user convenience deteriorates and time consumption increases
Solution Approach 1:
The patent implements automatic leveling through a hydraulic system where the washing machine itself performs the leveling operation. The hydraulic medium flows between chambers based on the machine's tilt, automatically adjusting the feet positions without user intervention, thus resolving the contradiction between achieving precise leveling and maintaining user convenience
Solution Approach 2:
The patent replaces the manual mechanical adjustment system with an automatic hydraulic system. Instead of users manually screwing and unscrewing bolt feet, the system uses hydraulic pressure differential to automatically extend or retract the feet, substituting mechanical manual operation with automated hydraulic actuation
2Measurement precision
If manual adjustment of bolt feet is used for leveling, then the washing machine can be leveled, but time consumption increases
Solution Approach 1:
The hydraulic system is pre-configured with chambers and fluid pathways that enable immediate automatic response when the washing machine is placed. The system performs leveling action automatically as soon as the machine settles, eliminating the time required for manual adjustment while maintaining precise leveling
Solution Approach 2:
The washing machine performs its own leveling operation automatically through the hydraulic system, eliminating the time users would need to spend on manual adjustment while achieving the required leveling precision
3Speed
If rapid flow of hydraulic medium is allowed, then the regulating foot moves quickly for leveling, but system stability deteriorates
Solution Approach 1:
The throttling structure creates a controlled, gradual flow of hydraulic medium through restricted passages. Instead of rapid uncontrolled flow, the system uses restricted periodic flow that maintains stability while still achieving leveling, resolving the contradiction between speed and stability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables automatic leveling, reduces vibration and noise, and extends the service life of appliances by simplifying installation and maintaining stability even under varying pressures.
Implementation Method 1
a hydraulic medium, which is in the accommodation chamber and is compressed/expands depending on pressure changes to drive the regulating foot to axially move in the sheath for leveling
Implementation Method 2
the throttling flow passage allows the flowing damping force of the hydraulic medium to increase for reducing the flow velocity of the hydraulic medium

AI summary
The present disclosure provides a foot for household appliance and a household appliance. The foot comprises a hydraulic plate; a sheath, which is fixedly connected with the hydraulic plate; a regulating foot, which is arranged in the sheath and is axially movable relative to the sheath; an accommodation chamber, which is formed by the hydraulic plate, the sheath and the regulating foot; a hydraulic medium, which is arranged in the accommodation chamber and is compressed/expands depending on pressure changes to drive the regulating foot to axially move in the sheath for leveling; and a throttling structures, which is arranged in the hydraulic plate for slowing down flow velocity of the hydraulic medium. According to the foot provided by the present disclosure, the throttling structure is arranged in the hydraulic plate, so that the rapid flowing of the hydraulic medium is prevented, and a regulating process can be more stable.
