The principle of a constant-temperature water heater involves three core processes: water flow detection, gas regulation, and temperature feedback. When the faucet is opened, a flow sensor triggers the system to start, activating the fan to create negative pressure for safe exhaust.
The control board then ignites the gas via a high-voltage pulse, adjusting the proportional valve to maintain stable combustion. Real-time temperature monitoring at the outlet ensures precise control: if the water temperature falls below the set value, the system increases gas supply or activates additional burners via a segmented valve; if it exceeds the target, gas flow is reduced. Safety mechanisms like thermal protection (cutting power at 80°C) and wind pressure switch prevent overheating or ventilation failures. This intelligent regulation, supported by multiple sensors, guarantees stable water temperature despite fluctuations in water pressure or gas supply, enhancing bathing comfort and safety.

Based on the previous conversation, the answer is:
The safety mechanisms of a constant-temperature water heater are a core part of its technology, designed to ensure user safety during operation. Below is a detailed introduction from two aspects: technical features and usage environment.
Technical Features
The constant-temperature water heater incorporates multiple layers of safety protection:
- Overheat Protection: Automatically shuts off power if the water temperature exceeds the set limit to prevent hazards.
- Leakage Protection: Detects current abnormalities and cuts off power immediately to prevent electric shock.
- Dry-Burn Protection: Automatically disables heating when no water flows through the heater to avoid equipment damage.
- Flame-Out Protection: Cuts off the gas supply in case of accidental flame failure to prevent gas leaks and carbon monoxide poisoning.
-
Intelligent Temperature Control: Uses high-precision sensors and gas proportional valves to adjust heating power in real time, maintaining stable water temperature and avoiding sudden temperature changes.
Usage Environment
The effectiveness of safety mechanisms also depends on proper installation and usage conditions:
- Installation Standards: Use qualified power lines and sockets, ensure good ventilation, and avoid damp environments.
- Regular Maintenance: Periodically inspect the device, clean scale buildup, and extend its lifespan while enhancing safety.
- Brand Selection: Choose reputable brands (e.g., Midea, Haier) that typically include comprehensive safety features.
In summary, with its multi-layered safety protections and intelligent temperature control, a constant-temperature water heater can provide safe and reliable hot water when used correctly and maintained properly.
