An electric steam control method, characterized by comprising:
- obtaining current water temperature data of a hot water tank and a current power supply mode;
- determining whether a temperature corresponding to the current water temperature data of the hot water tank is within a preset temperature range;
- and if the temperature is within the preset temperature range, entering a heat preservation mode;
- or if the temperature is not within the preset temperature range, detecting whether an alternating current (AC) power is currently available, and performing a power supply by using the AC power if the AC power is available, or generating a water temperature alarm signal if the AC power is unavailable;
- heating, by a heater, a medium in the hot water tank in response to a heating signal, and giving a first alarm in response to the water temperature alarm signal;
- in the heat preservation mode, detecting whether a working state is currently in place;
- and if the working state is in place, detecting whether the AC power is currently available and generating a steam ejection signal, and performing the power supply by using the AC power if the AC power is available, or performing the power supply by using a direct current (DC) power if the AC power is unavailable;
- or if the working state is not in place, maintaining the heat preservation mode;
- and
- ejecting steam in response to the steam ejection signal;
- and
- before determining whether the temperature corresponding to the current water temperature data of the hot water tank is within the preset temperature range, further comprising:
- obtaining current water volume data of the hot water tank;
- determining whether a first water volume corresponding to the current water volume data of the hot water tank reaches a preset hot water volume, and performing a water temperature detection if the first water volume reaches the preset hot water volume, or generating a water pumping signal and a hot water volume alarm signal if the first water volume does not reach the preset hot water volume;
- supplying water to the hot water tank from a cold water tank in response to the water pumping signal;
- and
- giving a second alarm in response to the hot water volume alarm signal, and
- before determining whether the first water volume corresponding to the current water volume data of the hot water tank reaches the preset hot water volume, further comprising:
- obtaining current water volume data of the cold water tank;
- determining whether a second water volume corresponding to the current water volume data of the cold water tank reaches a preset cold water volume, and performing a hot water volume detection if the second water volume reaches the preset cold water volume, or generating a cold water volume alarm signal and a stop signal if the second water volume does not reach the preset cold water volume;
- and
- giving a third alarm in response to the cold water volume alarm signal, and suspending operations of the electric steam control method in response to the stop signal.
