[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 exhaust pipe 1 and a fan 2, and the gas water heater also includes a heating component 3, a water inlet temperature sensor 4, and a controller 5. The heating component is arranged between the smoke exhaust holes of the smoke exhaust pipe, as shown in FIG. Figure 2 As shown, the control method includes:

[0056] S1. Obtain the water inlet temperature value of the gas water heater;

[0057] In this embodiment, the inlet water temperature value of the gas water heater is obtained through the inlet water temperature sensor.

[0058] S2. If the detected water inlet temperature is lower than the preset temperature, a first actual speed value of the fan is obtained;

[0059] S3. If it is detected that the difference between the first actual speed value and the first target speed value is greater than the first preset threshold value, it is determined that the smoke exhaust pipe is in a blocked state, the fan is controlled to stop running, and the heating component is powered on to heat the smoke exhaust pipe.

[0060] In this embodiment, the preset temperature value, the first target speed value, and the first preset threshold value are all set according to actual conditions and are not specifically limited here.

[0061] In an optional embodiment, if Figure 1 As shown, the gas water heater further includes a heat-conducting component 6, which is arranged outside the smoke exhaust pipe. S3 includes:

[0062] S31. If it is detected that the difference between the first actual speed value and the first target speed value is greater than the first preset threshold value, it is determined that the smoke exhaust pipe is in a blocked state, the fan is controlled to stop running, and the heating component is energized to transfer the heat generated by the heating component to the smoke exhaust pipe through the heat conducting component to heat the smoke exhaust pipe.

[0063] In this embodiment, the heating component can be an electric heating wire, and the heat-conducting component can be a heat-conducting copper sheet; the electric heating wire is evenly distributed between the smoke exhaust holes of the smoke exhaust pipe body, and the heat-conducting copper sheet is perpendicular to the arrangement direction of the electric heating wire, evenly distributed between the smoke exhaust holes, and close to the outside of the smoke exhaust pipe body.

[0064] In an optional embodiment, the gas water heater further includes a controller, and the control method further includes:

[0065] The power-on time and / or the power-on current value of the heating component are adjusted by the controller.

[0066] In this embodiment, one end of the electric heating wire is connected to a controller, and the controller can adjust the power-on time and / or current of the electric heating wire.

[0067] In an optional embodiment, before S1, the control method further includes:

[0068] The fan is controlled to operate according to a first preset current value.

[0069] During the specific implementation process, in low temperature weather in winter, the gas water heater turns on the antifreeze mode when it is powered on, and the water inlet temperature sensor reads the water inlet temperature value T. When the water inlet temperature value T is less than the preset temperature value (i.e., the antifreeze critical temperature), the controller sends a signal to start the fan, and the fan runs at a first preset current value (for example, A1 mA). The controller reads the first actual speed value of the fan, and compares it with the first target speed value under the current state of the first preset current value. If the speed difference is greater than the first preset threshold value r1, it means that the smoke exhaust hole is blocked. The controller will control the fan to stop running and energize the electric heating wire on the outside of the smoke exhaust pipe to generate heat. At the same time, the thermal conductive copper sheet quickly transfers the heat to the vicinity of each smoke exhaust hole, accelerating the melting of the ice layer attached to the outside of the smoke exhaust pipe, thereby ensuring the normal operation of the gas water heater.

[0070] In an optional embodiment, the control method further includes:

[0071] After the heating component is powered on for a first preset time, if it is detected that the difference between the first actual speed value and the first target speed value is less than or equal to a first preset threshold value, the heating component is powered off;

[0072] Controlling the fan to operate according to a second preset current value;

[0073] Acquire a second actual speed value and a second target speed value of the fan;

[0074] If it is detected that the difference between the second actual speed value and the second target speed value is greater than the second preset threshold value, the heating component is powered on to heat the smoke exhaust pipe;

[0075] Among them, the second preset current value is greater than the first preset 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.

[0076] In this embodiment, the second target speed value and the second preset threshold value are set according to actual conditions and are not specifically limited here.

[0077] In an optional embodiment, the control method further includes:

[0078] If it is detected that the difference between the second actual speed value and the second target speed value is less than or equal to the second preset threshold value, the fan is controlled to stop running, and the water inlet temperature value of the gas water heater is cyclically detected.

[0079] During the specific implementation process, after the electric heating wire has worked for the first preset time (for example, X1 minutes), the controller restarts the fan. If the exhaust pipe is detected to be blocked again, and the difference between the first actual speed value and the first target speed value of the fan is still greater than the first preset threshold value r1, it means that the ice layer on the outside of the exhaust pipe has not melted. This state does not meet the state requirements for starting the gas water heater. The electric heating wire will continue to be energized for heating until the speed difference of the fan is less than or equal to the first preset threshold value r1, and then the electric heating wire stops working. The fan is controlled to operate according to a second preset current value (for example, (A1+A2) mA); a second actual speed value and a second target speed value of the fan corresponding to the second preset current value are obtained; if it is detected that the difference between the second actual speed value and the second target speed value is greater than a second preset threshold value r2, the heating component is energized to heat the exhaust pipe; the blockage of the exhaust pipe can be detected more accurately, and the condensate (for example, ice layer) outside the exhaust pipe can be cleared more thoroughly. After the second preset time X2 minutes, the controller receives the water inlet temperature sensor signal again, and makes another judgment on the status of the exhaust pipe and the whole machine, so as to implement the antifreeze mode of the gas water heater in winter, thereby ensuring that the gas water heater can start normally.

[0080] This embodiment determines that when the smoke exhaust pipe is in a blocked state based on the inlet water temperature value of the gas water heater and the speed value of the fan, the fan is controlled to stop running and the heating component is energized to heat the smoke exhaust pipe, thereby avoiding blockage of the smoke exhaust pipe. The smoke exhaust pipe of the gas water heater can be started when it is frozen in winter and resume normal working state, thereby ensuring the normal operation of the gas water heater.

[0086] The second acquisition module 22 is used to acquire a first actual speed value of the fan if the detected water inlet temperature value is less than a preset temperature value;

[0087] The first control module 23 is used to determine that the smoke exhaust pipe is in a blocked state, control the fan to stop running, and energize the heating component to heat the smoke exhaust pipe if it is detected that the difference between the first actual speed value and the first target speed value is greater than a first preset threshold.

[0088] In an optional embodiment, if Figure 1 As shown, the gas water heater also includes a heat-conducting component 6, which is arranged outside the smoke exhaust pipe. The first control module is used to determine that the smoke exhaust pipe is in a blocked state if it is detected that the difference between the first actual speed value and the first target speed value is greater than the first preset threshold value, control the fan to stop running, and energize the heating component, and transfer the heat generated by the heating component to the smoke exhaust pipe through the heat-conducting component to heat the smoke exhaust pipe.

[0089] In this embodiment, the heating component can be an electric heating wire, and the heat-conducting component can be a heat-conducting copper sheet; the electric heating wire is evenly distributed between the smoke exhaust holes of the smoke exhaust pipe body, and the heat-conducting copper sheet is perpendicular to the arrangement direction of the electric heating wire, evenly distributed between the smoke exhaust holes, and close to the outside of the smoke exhaust pipe body.

[0090] In an optional embodiment, the gas water heater further includes a controller, and the control system further includes:

[0091] The adjustment module is used to adjust the power-on time and / or the power-on current value of the heating component through the controller.

[0092] In this embodiment, one end of the electric heating wire is connected to a controller, and the controller can adjust the power-on time and / or current of the electric heating wire.

[0093] In an optional embodiment, the control system further includes:

[0094] The second control module is used to control the fan to operate according to a first preset current value.

[0095] During the specific implementation process, in low temperature weather in winter, the gas water heater turns on the antifreeze mode when it is powered on, and the water inlet temperature sensor reads the water inlet temperature value T. When the water inlet temperature value T is less than the preset temperature value (i.e., the antifreeze critical temperature), the controller sends a signal to start the fan, and the fan runs at a first preset current value (for example, A1 mA). The controller reads the first actual speed value of the fan, and compares it with the first target speed value under the current state of the first preset current value. If the speed difference is greater than the first preset threshold value r1, it means that the smoke exhaust hole is blocked. The controller will control the fan to stop running and energize the electric heating wire on the outside of the smoke exhaust pipe to generate heat. At the same time, the thermal conductive copper sheet quickly transfers the heat to the vicinity of each smoke exhaust hole, accelerating the melting of the ice layer attached to the outside of the smoke exhaust pipe, thereby ensuring the normal operation of the gas water heater.

[0096] In an optional embodiment, the control system further includes:

[0097] a third control module, configured to, after the heating component is powered on for a first preset time, power off the heating component if it is detected that the difference between the first actual speed value and the first target speed value is less than or equal to a first preset threshold value;

[0102] In this embodiment, the second target speed value and the second preset threshold value are set according to actual conditions and are not specifically limited here.

[0103] In an optional embodiment, the control system further includes:

[0104] The fifth control module is used to control the fan to stop running and cyclically detect the water inlet temperature value of the gas water heater if it is detected that the difference between the second actual speed value and the second target speed value is less than or equal to the second preset threshold value.

[0105] During the specific implementation process, after the electric heating wire has worked for the first preset time (for example, X1 minutes), the controller restarts the fan. If the exhaust pipe is detected to be blocked again, and the difference between the first actual speed value and the first target speed value of the fan is still greater than the first preset threshold value r1, it means that the ice layer on the outside of the exhaust pipe has not melted. This state does not meet the state requirements for starting the gas water heater. The electric heating wire will continue to be energized for heating until the speed difference of the fan is less than or equal to the first preset threshold value r1, and then the electric heating wire stops working. The fan is controlled to operate according to a second preset current value (for example, (A1+A2) mA); a second actual speed value and a second target speed value of the fan corresponding to the second preset current value are obtained; if it is detected that the difference between the second actual speed value and the second target speed value is greater than a second preset threshold value r2, the heating component is energized to heat the exhaust pipe; the blockage of the exhaust pipe can be detected more accurately, and the condensate (for example, ice layer) outside the exhaust pipe can be cleared more thoroughly. After the second preset time X2 minutes, the controller receives the water inlet temperature sensor signal again, and makes another judgment on the status of the exhaust pipe and the whole machine, so as to implement the antifreeze mode of the gas water heater in winter, thereby ensuring that the gas water heater can start normally.
