[0053] In the embodiments of the present disclosure, the collection, storage, use, processing, transmission, provision and disclosure of user personal information involved are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0054] Example 1

[0055] 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 pipe 1 and a fan 2. The gas water heater also includes a magnetic component 3, a controller 4 and a cylinder cover 5. The smoke pipe 1 includes an induction coil 11. In this embodiment, an induction coil is installed inside the smoke pipe, and a magnetic component is designed on the outside of the corresponding smoke pipe body. One end of the magnetic component is connected to the smoke pipe, and the other end is away from the smoke pipe. Multiple matching induction coils and magnetic components are designed inside and outside the smoke pipe. The magnetic component is made of memory alloy material. Figure 2 As shown, the control method includes:

[0056] S1. In response to the inlet water temperature value of the gas water heater being less than a preset temperature value, obtaining a first actual speed value of the fan;

[0057] S2. If it is detected that the difference between the first actual speed value and the target speed value is greater than a first preset threshold value, the induction coil is energized at a preset frequency to control the magnetic attraction component to knock the cigarette pipe at a preset frequency.

[0058] In this embodiment, when the temperature is low in winter, the gas water heater starts the automatic protection program to prevent the smoke pipe from being frozen and blocked, which may cause the gas water heater to be unable to be used normally. The gas water heater reads the inlet water temperature, and when the inlet water temperature of the gas water heater is lower than the preset temperature value a℃, the antifreeze program starts.

[0059] In this embodiment, the preset temperature value, the preset frequency, and the first preset threshold are all set according to actual conditions and are not specifically limited here.

[0060] This embodiment controls the induction coil to be energized to control the magnetic attraction component to knock on the smoke pipe at a preset frequency, thereby clearing the ice layer attached to the outside of the smoke pipe, preventing the smoke pipe from being blocked, and ensuring the normal operation of the gas water heater in terms of the control program.

[0061] In an optional embodiment, the control method further includes:

[0062] If it is detected that the difference between the actual speed value and the target speed value is greater than the first preset threshold value, the induction coil is powered off at a preset frequency to control the magnetic attraction component to move away from the smoke pipe at a preset frequency.

[0063] In an optional embodiment, before the step of obtaining the first actual speed value of the fan in S1, the control method further includes:

[0064] Controlling the fan to operate according to a first current value;

[0065] In an optional embodiment, the magnetic attraction component is made of memory alloy material.

[0066] In the specific implementation process, the antifreeze program is started, the controller starts the fan, and the fan runs at a first current value of A1 mA. The controller reads the first actual speed value of the fan. If the difference between the first actual speed value and the target speed value is greater than the first preset threshold value r1, the cleaning program starts to run, and the controller transmits a signal to the induction coil. After the induction coil is energized, a magnetic field is generated, and the magnetic component starts to move and knock on the smoke exhaust port of the smoke pipe. The controller turns on and off the induction coil at a preset frequency. When the induction coil is turned on, the magnetic component instantly approaches the smoke pipe and knocks on the wall. After the induction coil is disconnected, due to the material properties of the magnetic component as a memory alloy, the magnetic component quickly moves away from the smoke pipe. The induction coil is cyclically powered on and off, so that the magnetic component knocks on the smoke pipe at a preset frequency, achieving the effect of removing the ice layer on the surface of the smoke pipe.

[0067] In an optional embodiment, the control method further includes:

[0068] If it is detected that the difference between the first actual speed value and the target speed value is less than or equal to the first preset threshold value, the magnetic attraction component is controlled to stop knocking the smoke pipe;

[0069] Controlling the fan to operate according to the second current value, and obtaining a second actual speed value of the fan;

[0070] If it is detected that the difference between the second actual speed value and the target speed value is greater than the second preset threshold value, the induction coil is controlled to be powered on and / or powered off again according to the preset frequency, so as to control the magnetic attraction component to knock on the smoke pipe and / or stay away from the smoke pipe according to the preset frequency;

[0071] Among them, the second current value is greater than the first current value, the second preset threshold is greater than the first preset threshold, and the second actual speed value is greater than the first actual speed value.

[0072] In this embodiment, the second preset threshold is set according to actual conditions and is not specifically limited here.

[0073] In an optional embodiment, the control method further includes:

[0074] If it is detected that the difference between the second actual speed value and the target speed value is less than or equal to the second preset threshold, the fan is controlled to stop running.

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

[0076] In response to the cigarette pipe being in a normal state, the induction coil is controlled to be in a power-off state, and one end of the magnetic attraction component is away from the induction coil.

[0077] In this embodiment, when the cigarette pipe is in a normal state, the induction coil and the reaction circuit are in an open circuit state, and one end of the magnetic attraction component is away from the induction coil.

[0078] In the specific implementation process, after the cleaning procedure is completed, the induction coil is disconnected from the power supply, and the controller starts the fan again. The fan runs at the first current value A1 mA. The controller reads the first actual speed of the fan. If the difference between the first actual speed value and the target speed value is greater than the first preset threshold value r1, the cleaning procedure is entered again until the difference between the first actual speed value and the target speed value is less than or equal to the first preset threshold value r1. At this time, the magnetic attraction component stops striking. In this state, the controller increases the fan current. The fan runs at a current of (A1+A2) mA. The controller reads the second actual speed value and the target speed value of the fan. If the speed difference is greater than the second preset threshold value r2, the cleaning procedure is entered again. If the speed difference is less than or equal to the second preset threshold value r2, the cleaning procedure stops. In this state, the smoke exhaust port of the smoke pipe is in an open state, and the gas water heater can operate normally.

[0079] The control method of the gas water heater of this embodiment is suitable for the antifreeze smoke pipe of the gas water heater in the north, so that the exhaust pipe of the gas water heater can be started and restored to normal working state when it is frozen in winter. Specifically, under the low temperature condition in winter, the gas water heater will continue to maintain a low temperature monitoring state, preventing the smoke outlet of the smoke pipe of the gas water heater from being frozen, thereby avoiding the user from being unable to use the gas water heater normally.

[0081] Corresponding to the aforementioned embodiment of a control method for a gas water heater, the present disclosure also provides an embodiment of a control system for a gas water heater.

[0085] In this embodiment, when the temperature is low in winter, the gas water heater starts the automatic protection program to prevent the smoke pipe from being frozen and blocked, which may cause the gas water heater to be unable to be used normally. The gas water heater reads the inlet water temperature, and when the inlet water temperature of the gas water heater is lower than the preset temperature value a℃, the antifreeze program starts.

The controller reads the first actual speed value of the fan. If the difference between the first actual speed value and the target speed value is greater than the first preset threshold value r1, the cleaning program starts to run, and the controller transmits a signal to the induction coil. After the induction coil is energized, a magnetic field is generated, and the magnetic component starts to move and knock on the smoke exhaust port of the smoke pipe. The controller turns on and off the induction coil at a preset frequency. When the induction coil is turned on, the magnetic component instantly approaches the smoke pipe and knocks on the wall. After the induction coil is disconnected, due to the material properties of the magnetic component as a memory alloy, the magnetic component quickly moves away from the smoke pipe. The induction coil is cyclically powered on and off, so that the magnetic component knocks on the smoke pipe at a preset frequency, achieving the effect of removing the ice layer on the surface of the smoke pipe.

[0094] In an optional embodiment, the control system further includes:

[0104] In this embodiment, when the cigarette pipe is in a normal state, the induction coil and the reaction circuit are in an open circuit state, and one end of the magnetic attraction component is away from the induction coil.

[0105] In the specific implementation process, after the cleaning procedure is completed, the induction coil is disconnected from the power supply, and the controller starts the fan again. The fan runs at the first current value A1 mA. The controller reads the first actual speed of the fan. If the difference between the first actual speed value and the target speed value is greater than the first preset threshold value r1, the cleaning procedure is entered again until the difference between the first actual speed value and the target speed value is less than or equal to the first preset threshold value r1. At this time, the magnetic attraction component stops striking. In this state, the controller increases the fan current. The fan runs at a current of (A1+A2) mA. The controller reads the second actual speed value and the target speed value of the fan. If the speed difference is greater than the second preset threshold value r2, the cleaning procedure is entered again.
