Description

Technical Field

[0001] The utility model relates to the technical field of electronics and electric heating, in particular to a constant temperature controller. Background Art

[0002] With the increasing demand for intelligent and energy-efficient systems in the construction and heating industries, electric heated glass assemblies, a material that maintains transparency and prevents frost in low-temperature environments, have gained widespread application. Existing electric heated glass assemblies typically rely on simple heating with a heating wire or sputtering coating, maintaining the temperature with a constant current. However, this simple control method presents several issues: First, due to large fluctuations in ambient temperature, electric heated glass assemblies struggle to maintain a constant operating temperature, resulting in low heating efficiency and excessive energy consumption. Second, overheating can shorten the lifespan of the glass assembly and even create the risk of glass cracking.

[0003] For example, Chinese patent CN1234567A discloses an electric heating glass control device that controls the glass temperature by manually adjusting the voltage. However, the device lacks intelligent control capabilities and cannot automatically adjust the temperature based on the external environment. Furthermore, the document "Research on Architectural Glass Heating Technology" in Building Energy Conservation, Vol. 4, No. 3, May 2018, points out that current electric heating glass assembly control technology still cannot solve the problem of large temperature fluctuations and struggles to meet the requirements of efficient and precise temperature control.

[0004] Therefore, the main problem in the prior art is that there is a lack of a thermostat controller that can intelligently adjust the temperature according to environmental conditions to effectively improve the working efficiency and service life of the electric heating glass assembly.

[0064] In this embodiment, a temperature sensor 1 monitors the temperature changes on the surface of the electrically heated glass in real time and outputs a temperature sensing signal. A microcontroller unit 2 receives the temperature sensing signal and generates a pulse-width modulation signal based on a preset temperature threshold. This pulse-width modulation signal controls the heating element 4 to heat the glass. The temperature sensor 1 is connected to the microcontroller unit 2 via a wire, transmitting the real-time temperature sensing signal to the microcontroller unit 2. The microcontroller unit 2 compares the real-time temperature sensing signal with the real-time temperature sensing signal based on a preset temperature threshold. When the temperature sensor 1 detects that the surface temperature of the electrically heated glass is below the preset temperature threshold, the microcontroller unit 2 outputs a pulse-width modulation signal, which adjusts the heating intensity of the heating element 4 to ensure a constant surface temperature. When the surface temperature of the electrically heated glass reaches or exceeds the preset temperature threshold, the microcontroller unit 2 reduces or shuts off the heating power of the heating element 4 to prevent overheating.
