Dual-Surface Ceramic Heating Plate Design for Uniform Water Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional sanitary cleaning devices suffer from low heating efficiency due to the limited heating distance and non-uniform heating of water, as the water only flows along a single-side heating surface of the ceramic heating plate, and the use of ribs on the heating surface further reduces efficiency.
Innovation Solution
A serpentine-shaped heating channel is formed by arranging multiple ceramic heating plates side by side with partitions in between, allowing water to flow along both sides of the plates, and integrating the heating device with a water tank to prevent immersion of heating elements, while incorporating an overflow and anti-siphon system to prevent scaling and maintain efficient heating.

Engineering Contradiction Analysis
1Length of moving object
If ribs are attached to the heating surface of the ceramic heating plate to form an S-shaped heating channel, then the heating distance of the cleaning water is extended, but a certain heating area of the ceramic heating plate is occupied, resulting in low heating efficiency
Solution Approach 1:
The invention transitions from a single-sided heating surface to a dual-sided heating configuration. Water flows through channels formed between multiple ceramic heating plates, allowing heat transfer from both sides of each plate. This dimensional change in the heating pathway enables extended heating distance without occupying the heating surface area, as the heating occurs through the water flow path between plates rather than on the plate surfaces themselves.
Solution Approach 2:
Multiple ceramic heating plates are arranged in a nested configuration within the heating cavity, with water channels formed between them. The plates are positioned such that water flows through the gaps between adjacent plates, utilizing the heating surfaces of multiple plates simultaneously. This nesting arrangement maximizes the use of heating surface area while providing sufficient heating distance through the multi-plate structure.
2Device complexity
If water only flows along a single-side heating surface of the ceramic heating plate, then the structure is simple, but the heating distance is short and the water cannot be fully and uniformly heated
Solution Approach 1:
The heating system is segmented into multiple ceramic heating plates arranged in sequence within the heating cavity. Each plate acts as an independent heating element, and water flows through channels between them. This segmentation allows the heating process to occur in multiple stages across different plates, ensuring uniform heating throughout the water flow path while maintaining a relatively simple overall structure.
Solution Approach 2:
The invention moves from single-sided to dual-sided heating by arranging water flow to pass between multiple plates. This creates a three-dimensional heating pathway where water is heated from both sides of each ceramic plate, significantly improving heating uniformity without requiring complex internal structures within individual plates.
3Device complexity
If the heating device is integrated with the water tank, then the overall structure is more compact and cost-effective, but the heating elements may be immersed in water, increasing the risk of scaling
Solution Approach 1:
The heating cavity is designed as a separate, integrated component within the water tank structure, but the heating elements are positioned such that they are not continuously immersed in the bulk water. Water is pumped from the storage cavity to the heating cavity for heating, then returned to the storage cavity. This extraction of the heating function into a dedicated cavity prevents continuous immersion and scaling while maintaining structural integration.
Solution Approach 2:
Water is pumped from the water storage cavity to the heating cavity before heating occurs. This preliminary action of transferring water to a separate heating cavity ensures that the heating elements are not in continuous contact with large volumes of water, reducing scaling risk while maintaining the integrated design. The heating process is performed on a controlled portion of water rather than the entire storage volume.

AI summary
Disclosed are a heating device, a sanitary water supply device, and a sanitary cleaning device. The heating device comprises a body and a ceramic heating plate. The body is provided with a heating chamber, and the ceramic heating plate is disposed in the heating chamber of the body. A heating flow channel is formed in the heating chamber, a first water inlet is provided at one end of the heating flow channel, and a first water outlet is provided at the other end of the heating flow channel. The ceramic heating plate has a first heating surface and a second heating surface facing away from each other, and a flow direction of the heating flow channel is along the first heating surface and the second heating surface in sequence. The present invention allows water to flow along the heating surfaces on two sides of the ceramic heating plate in sequence, thus increasing the heating distance of the water in the heating chamber, allowing the water to be heated evenly and sufficiently in the heating chamber, and improving the heating efficiency of the ceramic heating plate.
