[0047] Example 1

[0048] 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, a fan 2, a movable component 3, a permanent magnet 4, an electromagnetic coil 5 and a controller 6. The smoke exhaust pipe 1 includes a primary smoke exhaust hole 11 and a secondary smoke exhaust hole 12. In an optional embodiment, the opening area of ​​the primary smoke exhaust hole is larger than the opening area of ​​the secondary smoke exhaust hole. It should be noted that the movable component can be a movable metal ring, such as Figure 2 As shown, the control method includes:

[0049] S1, in response to the primary smoke exhaust hole of the gas water heater being frozen and the ignition of the gas water heater being abnormal, controlling the electromagnetic coil to be energized so that the movable component moves from one side of the permanent magnet to one side of the electromagnetic coil, and controlling the secondary smoke exhaust hole to open;

[0050] In an optional embodiment, when the electromagnetic coil is energized, the magnetic field strength of the electromagnetic coil is greater than the magnetic field strength of the permanent magnet.

[0051] S2, obtaining the actual speed value of the fan;

[0052] S3. If it is detected that the difference between the actual speed value and the target speed value is smaller than a preset threshold value, the gas water heater is controlled to operate according to the control instruction.

[0053] In this embodiment, the smoke exhaust pipe body is designed with a primary smoke exhaust hole and a secondary smoke exhaust hole. The opening area of ​​the primary smoke exhaust hole is much larger than that of the secondary smoke exhaust hole. Under normal conditions, the primary smoke exhaust hole is normally open. The secondary smoke exhaust hole is designed to be covered with a movable metal ring and is normally closed.

[0054] The movable metal ring is installed between the permanent magnet and the electromagnetic coil. The permanent magnet is fixed on the smoke exhaust pipe body, close to the primary smoke exhaust hole. The electromagnetic coil is installed far away from the primary smoke exhaust hole. When not powered, the electromagnetic coil does not generate magnetism. Affected by the magnetism of the permanent magnet, the movable metal ring is close to the permanent magnet ring.

[0055] When powered on, the electromagnetic coil generates a magnetic field whose magnetism is greater than that generated by the permanent magnet. The movable metal ring moves to one side of the electromagnetic coil, and the secondary smoke exhaust hole opens.

[0056] In the winter environment in northern regions, if the first-level smoke exhaust hole of the exhaust pipe is not frozen, the gas water heater can operate normally according to user instructions, and the second-level smoke exhaust hole remains closed.

[0057] It should be noted that the preset threshold is set according to actual conditions and is not specifically limited here.

[0058] In an optional embodiment, the control method further includes:

[0059] If it is detected that the difference between the actual speed value and the target speed value is greater than or equal to a preset threshold value, the gas water heater is controlled to operate according to the preset load so as to heat the first-level smoke exhaust hole through the heat generated by the gas water heater.

[0060] In the specific implementation process, if the primary smoke exhaust hole of the smoke exhaust pipe is frozen, when the gas water heater has an abnormality during the first ignition, the proportional valve is closed, and after the fan is cleaned, the gas water heater is ignited for the second time. If the secondary ignition is also abnormal, the main control board sends a signal, the electromagnetic coil is energized, the movable metal ring moves to the side of the electromagnetic coil, and the secondary smoke exhaust hole opens. At the same time, the fan runs at a preset current (for example, A1 mA), and the main control board reads and calculates the difference between the actual speed value and the target speed value of the fan: if the difference is less than the preset threshold r, it means that the gas water heater can work normally under the user's control instruction (for example, the control instruction is that the user requires the gas water heater to reach 45 degrees water); if the difference is greater than or equal to the preset threshold r, the gas water heater will run at a preset load (for example, the gas water heater is heated at a minimum load) to heat the primary smoke exhaust hole with the heat generated by the gas water heater.

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

[0062] After the gas water heater is controlled to run for a first preset time according to the control instruction, the electromagnetic coil is powered off and the secondary smoke exhaust hole is closed, and the actual speed value of the fan is re-detected;

[0063] If the difference between the detected actual speed value and the target speed value is still less than the preset threshold, the gas water heater continues to be controlled according to the control instruction;

[0064] If the difference between the detected actual speed value and the target speed value is greater than or equal to the preset threshold, the secondary smoke exhaust hole is controlled to open again until it is detected that the gas water heater operates normally according to the control instruction.

[0065] In this embodiment, after the gas water heater is controlled to run for the first preset time X1 minute according to the control instruction, the main control board sends a signal, the electromagnetic coil is powered off, and the secondary smoke exhaust hole is closed. In this state, the main control board calculates the difference between the actual speed value and the target speed value of the fan. If the difference is still less than the preset threshold value r, the gas water heater can continue to run according to the user's instruction; if the difference is greater than or equal to the preset threshold value r, the secondary smoke exhaust hole is opened again until the main control board determines that the gas water heater can continue to maintain normal instruction operation.

[0066] In an optional embodiment, the control method further includes:

[0067] After controlling the gas water heater to run at the preset load for the second preset time, if the difference between the re-detected actual speed value of the fan and the target speed value is greater than or equal to the preset threshold, the gas water heater is controlled to run at the preset load again until the condensate outside the first-level smoke exhaust hole is cleared by the heat generated by the gas water heater, and then the first-level smoke exhaust hole is controlled to open.

[0068] In this embodiment, after the gas water heater is controlled to run at a preset load for a second preset time X2 minutes, the main controller recalculates the difference between the actual speed value and the target speed value of the fan. If the difference is greater than the preset threshold value r, the gas water heater is again operated at the minimum load for a second preset time X2 minutes until the surface condensate (for example, ice layer) of the first-level smoke exhaust pipe hole gradually melts due to the heat in the flue gas, and the first-level smoke exhaust hole is controlled to open until the gas water heater operates according to the user's instructions.

[0069] In this embodiment, when the primary smoke exhaust hole of the gas water heater is frozen and the ignition of the gas water heater is abnormal, the electromagnetic coil is controlled to be energized so that the movable component moves to one side of the electromagnetic coil, and the secondary smoke exhaust hole is controlled to open; and the difference between the actual speed value and the target speed value is compared with the preset threshold value to realize controlling the operation of the gas water heater according to the control instruction, ensuring that the gas water heater can be started normally and resume normal working state when the smoke exhaust pipe is blocked in winter, solving the problem of complete blockage of the smoke exhaust pipe in winter, realizing the normal start-up of the forced exhaust gas water heater in winter, and reducing safety hazards.

[0084] In the specific implementation process, if the primary smoke exhaust hole of the smoke exhaust pipe is frozen, when the gas water heater has an abnormality during the first ignition, the proportional valve is closed, and after the fan is cleaned, the gas water heater is ignited for the second time. If the secondary ignition is also abnormal, the main control board sends a signal, the electromagnetic coil is energized, the movable metal ring moves to the side of the electromagnetic coil, and the secondary smoke exhaust hole opens. At the same time, the fan runs at a preset current (for example, A1 mA), and the main control board reads and calculates the difference between the actual speed value and the target speed value of the fan: if the difference is less than the preset threshold r, it means that the gas water heater can work normally under the user's control instruction (for example, the control instruction is that the user requires the gas water heater to reach 45 degrees water); if the difference is greater than or equal to the preset threshold r, the gas water heater will run at a preset load (for example, the gas water heater is heated at a minimum load) to heat the primary smoke exhaust hole with the heat generated by the gas water heater.

[0089] In this embodiment, after the gas water heater is controlled to run for the first preset time X1 minute according to the control instruction, the main control board sends a signal, the electromagnetic coil is powered off, and the secondary smoke exhaust hole is closed. In this state, the main control board calculates the difference between the actual speed value and the target speed value of the fan. If the difference is still less than the preset threshold value r, the gas water heater can continue to run according to the user's instruction; if the difference is greater than or equal to the preset threshold value r, the secondary smoke exhaust hole is opened again until the main control board determines that the gas water heater can continue to maintain normal instruction operation.

[0092] In this embodiment, after the gas water heater is controlled to run at a preset load for a second preset time X2 minutes, the main controller recalculates the difference between the actual speed value and the target speed value of the fan. If the difference is greater than the preset threshold value r, the gas water heater is again operated at the minimum load for a second preset time X2 minutes until the surface condensate (for example, ice layer) of the first-level smoke exhaust pipe hole gradually melts due to the heat in the flue gas, and the first-level smoke exhaust hole is controlled to open until the gas water heater operates according to the user's instructions.
