Induction Range Coil Support for Constant Heating Gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric ranges with working coils disposed at the upper end of a base plate often experience sagging due to uneven elastic support, leading to an inconsistent gap between the working coil and objects being heated, which affects heating efficiency.
Innovation Solution
The implementation of elastic supporters disposed at the upper end of an air guide beneath the base plate to provide uniform support, maintaining a constant gap and preventing sagging, utilizing a combination of leaf springs or elastic rubber blocks to elastically support the base plate along its widthwise direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastic rods are used to support the base plate at different positions, then the base plate can be supported, but uneven elastic force causes the base plate to tilt and sag
Solution Approach 1:
The patent applies local quality by positioning elastic supporters specifically at the four corners of the base plate rather than uniformly distributed support. This localized support strategy addresses the specific sagging problem at corner regions while maintaining overall base plate stability and ensuring consistent gap between the working coil and cooking vessel.
Solution Approach 2:
The elastic supporters function as counterweight elements by providing upward elastic force to counterbalance the downward gravitational force and weight of the working coil. This prevents the base plate from sagging and maintains proper positioning, thereby ensuring reliable operation and consistent heating gap.
2Productivity
If the working coil is disposed at the upper end of the base plate, then heating function is achieved, but the base plate bends downward due to weight
Solution Approach 1:
The elastic supporters provide upward elastic counterforce to balance the downward weight of the working coil. This prevents base plate deformation while maintaining the working coil's proper positioning for effective heating operation.
Solution Approach 2:
The elastic supporters act as pre-installed cushioning elements that absorb and compensate for the gravitational load of the working coil before it causes excessive deformation. This beforehand support ensures the base plate maintains its shape and the working coil remains properly positioned for heating.
3Reliability
If elastic supporters are added to support the base plate, then sagging is prevented, but device complexity increases
Solution Approach 1:
The patent employs asymmetric positioning of elastic supporters at the four corners of the base plate rather than symmetric uniform distribution. This asymmetric arrangement provides effective support with minimal components, preventing sagging while avoiding excessive complexity that would result from more numerous or differently arranged support elements.

This configuration ensures a consistent gap between the working coil and objects being heated, enhancing heating efficiency and stability by preventing base plate sagging and maintaining uniform heat distribution.
Implementation Method 1
a lower end of the base plate, which allows a working coil to be placed at the upper end thereof, may be supported by the elastic supporters disposed at the upper end of the air guide
Implementation Method 2
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.
Implementation Method 3
eddy current produced in the generated magnetic field is used to heat an object to be heated
Implementation Method 4
In a resistance heating method, electric current is supplied to a metallic resistance wire or a non-metallic heat generation element such as silicon carbide to generate heat, and the generated heat is radiated or conducted to heat an object to be heated
