Electric Range Base Plate Support for Constant Coil Gap
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 an inconsistent gap between the cooking vessel and the working coil, affecting heating efficiency.
Innovation Solution
The implementation of elastic supporters at the upper end of an air guide beneath the base plate to prevent sagging, combined with a bracket and additional elastic members for supplementary support, maintains a constant gap and ensures uniform heating.

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 base plate is divided into multiple independent support zones, each supported by separate elastic rods positioned at different locations. This segmentation allows each rod to independently manage local deformation, preventing cumulative sagging effects across the entire base plate structure.
Solution Approach 2:
Different regions of the base plate are provided with varying support characteristics through strategically positioned elastic rods. The elastic rods are located at specific positions (front, rear, left, right sides) to address local deformation tendencies, ensuring uniform gap maintenance in different areas of the cooking surface.

If working coil is disposed at center of base plate, then heating function is achieved, but base plate bends downward due to weight concentration
Solution Approach 1:
Elastic rods are positioned at the front and rear sides of the base plate, away from the center where the working coil is located. These rods provide counterbalancing support forces that offset the downward bending moment caused by the concentrated weight of the working coil, maintaining the base plate's horizontal shape.
Solution Approach 2:
Instead of providing support only at the center (one-dimensional approach), the elastic rods are distributed across multiple dimensions of the base plate (front-rear axis and left-right axis). This multi-dimensional support distribution effectively counters the centerward bending force from the working coil.

Function Achieved in This Case
This configuration stabilizes the base plate, maintains a consistent gap between the cooking vessel and the working coil, enhancing heating efficiency and preventing deformation, thus ensuring uniform heating performance.

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.
