Common electrical equipment includes heating equipment such as gas water heaters. During actual use, different currents and wind speeds are required for different switches. Traditionally, when switching from the first stage to a higher stage, regardless of the wind speed, the switch is made based on the current current and wind speed, resulting in the inability to match the wind speed and current. If the flame is cut off with a small current at a high wind speed, the flame is easily blown out; if the flame is cut off with a large current at a low wind speed, excessive gas will cause deflagration.

A third judgment module for judging whether the current wind speed of the gas water heater is within the preset wind speed range; if so, cut off according to the current wind speed and the minimum preset current; if not, execute the third switching process on the gas water heater. The third judgment module includes: A third judgment unit for judging whether the current wind speed is less than the minimum preset wind speed. If so, cut off according to the minimum preset wind speed and the minimum preset current; if not, cut off according to the maximum preset wind speed and the minimum preset current.

8. The cut-off system of the gas water heater according to claim 5, characterized in that, The minimum preset current is IA, and IA = Imin + (Imax - Imin) * A%; where Imin is the minimum current, Imax is the maximum current, and A% is the ratio; and / or, the maximum preset current is IB, and IB = Imin + (Imax - Imin) * B%; where Imin is the minimum current, Imax is the maximum current, and B% is the ratio; and / or, the minimum preset wind speed to the maximum preset wind speed are a and b respectively, and Nmin < a < b < Nmax; where Nmin is the minimum limit current of the first stage, and Nmax is the maximum limit current of the first stage.

9. A gas water heater, comprising a memory, a processor, and a computer program stored on the memory and configured to run on the processor, characterized in that, When the processor executes the computer program, it implements the gas water heater cut-off method described in any one of claims 1 to 4.

10. A computer-readable storage medium having a computer program stored thereon, characterized in that, When the program is executed by the processor, it implements the gas water heater cut-off method described in any one of claims 1 to 4.
