AI Technical Summary
⚠Technical Problem
Existing instant electric water heaters operate at high power, leading to safety hazards such as circuit overload and tripping, and cannot effectively meet users' instant heating needs.
⚗Method used
The design combines a thermal storage heater and an instantaneous heater. The thermal storage heater stores hot water in advance, and the instantaneous heater performs secondary heating. The heating power is adjusted by a silicon controlled rectifier (SCR) to ensure stable water temperature.
🎯Benefits of technology
It improves the efficiency of hot water supply, reduces the requirements for power facilities, reduces the safety hazards of circuit overload and tripping, and enhances the user experience.
