Ceramic Heating Plate Serpentine Flow Design for Uniform Water Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional sanitary cleaning devices using ceramic heating plates for heating cleaning water suffer from low heating efficiency due to limited heating distance and non-uniform heating, as the water only flows along a single-side heating surface, and the addition of ribs to extend the heating path occupies part of the heating area, reducing efficiency further.
Innovation Solution
The design features a heating channel within a heating cavity with multiple ceramic heating plates arranged side by side, where the cleaning water flows sequentially along both heating surfaces, forming a serpentine path, and is pumped through a serpentine-shaped channel to enhance heating distance and uniformity, with an integrated water tank structure to prevent scaling and improve heating efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If ribs are added to extend the heating path, then the heating distance is extended, but the heating area of the ceramic heating plate is occupied, resulting in low heating efficiency
Solution Approach 1:
The invention transitions from single-side heating to double-side heating by routing water flow through both surfaces of the ceramic heating plate. The heating channel is designed to enter from one side, traverse through the plate thickness, and exit to another channel that allows heating from the opposite side, effectively utilizing both heating surfaces simultaneously without requiring additional ribs that would occupy heating area.
2Device complexity
If water flows along a single-side heating surface, then the structure is simple, but the heating distance is short and heating is non-uniform
Solution Approach 1:
The heating process is segmented into two independent paths: one for the first heating surface and another for the second heating surface. Separate water channels are provided for each side, allowing the water flow to be divided and distributed across both heating surfaces, thereby extending the total heating distance while maintaining uniform heating across different regions.
3Area of stationary object
If multiple ceramic heating plates are arranged side by side, then the heating area is increased, but the device complexity increases
Solution Approach 1:
Multiple ceramic heating plates are merged into a single integrated assembly with unified water inlet and outlet channels. The channels are designed to distribute water flow across all heating plates simultaneously through a common water supply system, allowing the heating plates to work together as one coordinated unit rather than independent components, thereby increasing heating area without proportionally increasing device complexity.

Function Achieved in This Case
The solution ensures thorough and uniform heating of cleaning water, reduces scaling, saves costs by integrating components, and enhances energy efficiency through external heat dissipation, while maintaining a compact design and preventing water backflow.
Implementation Method 1
The heating device generally uses a ceramic heating plate as a heater, and the cleaning water only flows along a single-side heating surface of the ceramic heating plate
