Electric Range Base Plate Elastic Support Gap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric ranges with working coils disposed at the center of a base plate tend to sag due to uneven elastic support, leading to inconsistent gaps between the cooking vessel and the working coil, affecting heating efficiency.
Innovation Solution
Elastic supporters are strategically placed at the upper end of an air guide beneath the base plate to prevent sagging, maintaining a constant gap between the cooking vessel and the working coil, ensuring uniform heating and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If elastic rods are used to support the base plate, then the base plate can be supported, but the base plate sags and tilts due to uneven elastic force, causing inconsistent gap between cooking vessel and working coil
Solution Approach 1:
The support system is segmented into multiple elastic rods positioned at different locations (center and corners) of the base plate. This segmentation allows independent adjustment of each rod's elastic force to achieve uniform support distribution and prevent sagging while maintaining consistent gap between the cooking vessel and working coil.
Solution Approach 2:
Different elastic rods are configured with different elastic forces according to their specific positions on the base plate. The center rod and corner rods have different elastic characteristics tailored to their local support requirements, ensuring optimal load distribution and preventing both sagging and tilting of the base plate.
2Adaptability or versatility
If working coil is disposed at the center of the base plate, then space utilization is improved, but the center of the base plate bends downward due to concentrated weight
Solution Approach 1:
An elastic rod is positioned at the center of the base plate directly beneath the working coil to provide upward counterbalancing force against the downward bending caused by the concentrated weight of the working coil. This central elastic support compensates for the sagging effect while maintaining the space-efficient central configuration.
Solution Approach 2:
The elastic rod at the center provides dynamic support that allows the base plate to flex within elastic limits while maintaining overall structural integrity. The elastic property enables the system to absorb and distribute the concentrated load from the working coil, preventing permanent deformation while preserving the compact central arrangement.
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 effectively prevents base plate sagging and maintains a consistent gap, enhancing heating efficiency and stability by providing elastic support to the base plate, ensuring uniform heating and reducing heat generation.
Implementation Method 1
Elastic supporters are strategically placed at the upper end of an air guide beneath the base plate to prevent sagging
Implementation Method 2
When electric current is supplied to a working coil or a heating coil, heat is generated while an object to be heated is inductively heated
Implementation Method 3
In an induction heating method, high-frequency power is supplied to a coil to generate a magnetic field around the coil, and eddy current produced in the generated magnetic field is used to heat an object to be heated made of a metallic material

AI summary
An electric range is provided in which a lower surface of a base plate, on an upper end of which a working coil is placed, may be supported by at least one elastic supporter disposed at an upper end of at least one air guide along a widthwise direction of the base plate, thereby preventing bending of the base plate and maintaining a constant gap between an object to be heated and the working coil.
