[0052] Example 1

[0053] A control method for a gas water heater provided in Example 1 of the present disclosure is as follows: Figure 1 As shown, the gas water heater includes a smoke exhaust pipe 1, an interlayer 2, a magnetic suction component 3 and a membrane 4. The smoke exhaust pipe 1 includes an induction coil 11, which is arranged inside the smoke exhaust pipe 1, and the magnetic suction component 3 is arranged outside the smoke exhaust pipe 1. A permanent magnet 5 is arranged outside the magnetic suction component 3. In this embodiment, an induction coil is installed inside the smoke exhaust pipe body, and a magnetic suction component is arranged outside the corresponding smoke exhaust pipe body. One end of the magnetic suction component is connected to the smoke exhaust pipe body, and the other end of the magnetic suction component is far away from the smoke exhaust pipe body. A plurality of matching induction coils and magnetic suction components are arranged inside and outside the exhaust pipe body, such as Figure 2 As shown, the control method includes:

[0054] S1, in response to the smoke exhaust pipe being in a frozen state and the fluid volume in the interlayer being greater than a preset threshold, obtaining the magnetic field strength of the magnetic field coil;

[0055] In this embodiment, the preset threshold is set according to actual conditions and is not specifically limited here.

[0056] S2. Control the current direction of the induction coil according to the magnetic field strength to control the magnetic attraction component to knock the smoke exhaust pipe, so that the smoke exhaust pipe is restored to a non-frozen state.

[0057] In this embodiment, when the smoke exhaust pipe is frozen, the fluid in the interlayer gradually begins to freeze, the volume of the fluid in the interlayer increases, the membrane pushes the reaction circuit to move, the Hall element approaches the induction coil, senses the magnetic field strength generated by the coil, changes the current direction of the induction coil according to the magnetic field strength, and the induction coil generates a magnetic field with the same magnetic pole as the permanent magnet. The magnetic attraction component moves away from the smoke exhaust pipe and begins to move, and the magnetic attraction component begins to knock on the frozen surface of the smoke exhaust port of the smoke exhaust pipe, breaking the ice layer attached to the smoke exhaust port, and the smoke exhaust pipe gradually returns to the state before freezing.

[0058] In an optional embodiment, if Figure 1 As shown, the gas water heater further includes a fan 6. After step S1, the control method further includes:

[0059] Control the fan to run according to the preset current and obtain the actual speed value of the fan;

[0060] If it is detected that the difference between the actual speed value and the target speed value is greater than the preset speed value, step S2 is executed.

[0061] In this embodiment, the preset current is set according to actual conditions and is not specifically limited here.

[0062] In an optional embodiment, if Figure 1 As shown, the gas water heater further includes an electric controller 7, and the control method further includes:

[0063] In response to the smoke exhaust pipe being in a non-frozen state, the electric controller is controlled to output a negative current to control the magnetic attraction component to be away from the induction coil.

[0064] In this embodiment, when the smoke exhaust pipe is in a non-frozen state (i.e., a normal state), the electronic controller is controlled to keep outputting a negative current, the induction coil generates a magnetic field, the magnetic poles of the induction coil are the same as those of the permanent magnet, the two repel each other, and one end of the magnetic attraction component is away from the induction coil.

[0065] In an optional embodiment, step S2 includes:

[0066] According to the magnetic field strength, the current direction of the induction coil is controlled to be adjusted to a positive direction or a negative direction according to a preset period, so as to control the magnetic attraction component to knock the smoke exhaust pipe according to a preset period, so that the smoke exhaust pipe is restored to a non-frozen state;

[0067] In this embodiment, the electric controller changes the current direction of the induction coil according to the magnetic field strength, and the induction coil generates a magnetic field with the same magnetic pole as the permanent magnet, attracting the magnetic attraction component away from the exhaust pipe and starting to move, and the magnetic attraction component begins to knock on the frozen surface of the exhaust port of the exhaust pipe. The power-on mode of the cleaning program is a periodic output of positive and negative current mode, and the induction coil continuously switches the magnetic pole, guiding the magnetic attraction component to periodically knock on the exhaust port of the exhaust pipe, so that the ice layer attached to the exhaust port breaks, and the exhaust pipe gradually recovers to the state before freezing.

[0068] It should be noted that the preset period is set according to actual conditions and is not specifically limited here.

[0069] In an optional embodiment, after step S2, the control method further includes:

[0070] If it is detected that the smoke exhaust hole of the smoke exhaust pipe is still in a closed state or the opening area of ​​the smoke exhaust hole is smaller than the preset area after the magnetic attraction component knocks on the smoke exhaust pipe for a preset time, the current value of the induction coil is increased until the smoke exhaust hole of the smoke exhaust pipe is in a non-closed state or the opening area of ​​the smoke exhaust hole is not less than the preset area.

[0071] In this embodiment, after the magnetic attraction component has worked for a period of time, the gas water heater determines whether the smoke exhaust pipe is conductive through the fan speed. When the smoke exhaust hole of the smoke exhaust pipe is still closed or the opening area is smaller than the preset area, the current value of the induction coil will be increased to continue the cleaning operation until the smoke exhaust hole of the smoke exhaust pipe is in a non-closed state or the opening area of ​​the smoke exhaust hole is not less than the preset area (that is, until the opening area of ​​the smoke exhaust pipe meets the combustion conditions of the gas water heater).

[0072] It should be noted that the preset time and preset area are set according to actual conditions and are not specifically limited here.

[0073] In an optional embodiment, if Figure 1 As shown, the gas water heater further includes a Hall element 8, a cylinder cover 9 and a water inlet temperature sensor 10, and step S1 includes:

[0074] In response to the smoke exhaust pipe being in a frozen state, the volume of the fluid in the interlayer is greater than a preset threshold, and the magnetic field strength of the magnetic field coil sensed by the Hall element is obtained.

[0075] In an optional embodiment, the control method further includes:

[0076] Obtain the difference value of the magnetic field strength sensed by the Hall element and the magnetic field coil;

[0077] The current value of the induction coil is controlled according to the difference value of the magnetic field strength to adjust the knocking strength of the magnetic attraction component knocking on the smoke exhaust pipe.

[0078] In this embodiment, the distance between the Hall element and the induction coil is different, and the intensity of the induced magnetic field is different. According to this difference, the electronic controller can control the current output by the electromagnetic coil to adjust the intensity of the cleaning operation.

[0079] This embodiment uses the fluid volume in the interlayer of the gas water heater in combination with the induction coil to control the magnetic attraction component to knock on the smoke exhaust pipe, so that the smoke exhaust pipe is restored to a non-frozen state, avoiding the problem of the gas water heater not being able to work normally due to the smoke exhaust pipe being blocked due to freezing. Even if the smoke exhaust pipe of the gas water heater is frozen in winter, the gas water heater can be started and restored to normal working state.
