[0002] With the rapid development of gas-fired hot water boilers, the high efficiency and environmental protection of hot water boilers have become the focus of people's attention. At present, due to the different altitudes of the production and use sites, the different temperatures of the production sites of various components and the assembly sites of the whole machine, or the differences in the parts of each product when it leaves the factory, the fan speed value set at the factory of the hot water boiler may not make the working state of the hot water boiler at the best air-fuel ratio. This is because: when the temperature or altitude changes, the wind speed of the fan will change, which will cause the air-fuel ratio of the whole machine to change; when the fan speed is low, the air-fuel ratio will decrease, which will cause the combustion of the hot water boiler to deteriorate, and it is easy to produce condensed water and flue gas emissions exceeding the standard; when the fan speed is high, the air-fuel ratio increases, and the heat brought out by the exhaust gas is high, resulting in low combustion efficiency. Therefore, how to intelligently adjust the fan speed of the hot water boiler to improve combustion efficiency and meet the exhaust gas emission standards has become an urgent problem to be solved.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0035] It should be noted that the terms "first", "second", "target", and "original" in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including", "having", and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices.

[0036] Figure 1 A flow chart of a method for adjusting the speed of a fan provided in an embodiment of the present application. This embodiment can be applied to the installation of a heating water boiler. Since the production site where the heating water boiler is generated and debugged is different from the installation site where the user uses the heating water boiler (such as different environments or climates), it is necessary to adjust the operating wind speed of the fan to keep the heating water boiler at an optimal air-fuel ratio. The method for adjusting the speed of a fan provided in this embodiment can be executed by a speed adjustment device for a fan provided in an embodiment of the present application. The device can be implemented by software and / or hardware and integrated in an electronic device that executes the method. Preferably, the electronic device in the embodiment of the present application can be a heating water boiler, and the execution subject that executes the method is a microcontroller of the heating water boiler.

[0037] See also Figure 1 The method of this embodiment includes but is not limited to the following steps:

[0038] S110. When it is detected that the heating water heater is successfully installed, a prompt message is generated to prompt the user to calibrate the wind speed of the fan in the heating water heater.

[0039] The heating water heater utilizes energy combustion to heat water to a certain temperature to meet the needs of domestic hot water or heating. In this embodiment, the heating water heater can be gas-fired or coal-fired, and the fan type can be direct current, mixed flow or other types. The prompt information is used to prompt the user or the installer to calibrate the fan speed of the heating water heater. This embodiment does not specifically limit the content and form of the prompt information.

[0040] In one embodiment, the heating water heater may be provided with a display screen and virtual or physical buttons for interacting with the user. During the process of the user or the installer installing the heating water heater, the microcontroller detects in real time whether the heating water heater is installed successfully; when the installation is detected to be successful, the microcontroller generates a prompt message, displays the prompt message on the display screen, and displays a confirmation button and a cancel button for operating the prompt message; at this time, the user or the installer can operate the confirmation button and the cancel button on the display screen according to actual use requirements, so that the microcontroller can adjust the fan speed of the heating water heater in the next step.

[0041] In another embodiment, the heating water boiler can be connected to a smart terminal, which refers to a device used to manage the heating water boiler, which can be a mobile phone, a tablet or a computer, etc. The smart terminal is configured with an application software for managing the heating water boiler. During the process of the user or the installer installing the heating water boiler, the microcontroller detects in real time whether the heating water boiler is installed successfully; when the installation is detected to be successful, the microcontroller generates a prompt message and sends the prompt message to the smart terminal so that the prompt message can be displayed to the user or the installer in the smart terminal; at this time, the user or the installer can confirm or cancel the prompt message through the confirmation button and the cancel button on the smart terminal according to actual use requirements. After the user or the installer operates the prompt message, the smart terminal sends the operation result of the prompt message to the microcontroller, and the microcontroller receives the operation result sent by the smart terminal so that the microcontroller can adjust the fan speed of the heating water boiler in the next step.

[0042] Furthermore, the heating water heater may be equipped with a climate detection component; before generating a prompt message for prompting to check the wind speed of the fan in the heating water heater, it also includes: detecting the first climate information of the installation site of the heating water heater through the climate detection component; determining whether the first climate information is consistent with the second climate information of the production site of the heating water heater; if not, executing the operation of generating a prompt message for prompting to check the wind speed of the fan. The climate information includes but is not limited to the local altitude and temperature. The first climate information is the climate information of the installation site of the heating water heater. The second climate information is the climate information of the production site of the heating water heater.

[0043] In an embodiment of the present application, when the fan of the heating water heater is produced and debugged, the second climate information (such as altitude and temperature) of the production site of the heating water heater is detected by the climate detection component, and the second climate information is stored in the preset storage unit of the microcontroller. When the microcontroller detects that the heating water heater is successfully installed at the installation site (such as the user's home), the first climate information (such as altitude and temperature) of the installation site of the heating water heater is detected by the climate detection component configured inside the heating water heater. Then the microcontroller compares whether the contents contained in the first climate information and the second climate information are consistent, such as comparing whether the altitude and temperature of the installation site and the production site are consistent. If the altitude difference between the installation site and the production site exceeds the preset height value or the seasonal average temperature difference between the installation site and the production site exceeds the preset temperature value, it will cause the fan running wind speed of the heating water heater to change when it is working at the installation site, then the microcontroller starts to execute the operation of generating a prompt information for prompting to verify the wind speed of the fan.

[0044] Optionally, a positioning component can be configured in the heating water heater to replace the climate detection component. When the fan of the heating water heater is produced and debugged, the second position information of the production site of the heating water heater is detected by the positioning component, and the second position information is stored in a preset storage unit of the microcontroller. When the microcontroller detects that the heating water heater is successfully installed at the installation site (such as the user's home), the first position information of the installation site is determined by the positioning component, and then the second climate information corresponding to the second position information and the first climate information corresponding to the first position information are determined.

[0045] It can be understood that in addition to adjusting the fan speed when the heating water boiler is initially installed, at any time after the heating water boiler is successfully installed (i.e. during the use of the heating water boiler), the user can manually trigger the physical button or virtual button of the fan speed adjustment function on the display screen of the heating water boiler, or trigger the corresponding virtual button on the smart terminal. At this time, the microcontroller starts to respond to the user's trigger operation to adjust the fan speed.

[0046] S120, receiving a confirmation operation for the prompt information, and controlling the heating water boiler to operate for a preset time under a calibrated working condition.

[0047] Among them, the calibration condition is the condition in which the fan of the heating water boiler operates at a predetermined wind speed value, that is, the fan pulse width modulation (Pulse Width Modulation, PWM) under a rated load is set for the fan of the heating water boiler. This embodiment does not specifically limit the value of PWM. Optionally, the calibration condition can be the maximum power load in the standard mode, or it can be 30% power load or 50% power load.

[0048] In the embodiment of the present application, after receiving the confirmation operation of the user or the installer on the prompt information, the microcontroller controls the heating water heater to operate for a preset time under the calibrated working condition so that the fan wind speed of the heating water heater reaches a stable state. The preset time can be a default time for the heating water heater to operate under the calibrated working condition when it is set at the factory. The user or the installer can adjust and set this time according to the specific situation. Optionally, the preset time can be set to 20 seconds.

[0049] S130. After a preset time, obtain the current wind speed value of the fan.

[0050] In the embodiment of the present application, after the fan of the heating water boiler runs for a preset time under the calibrated working condition, the microcontroller obtains the current wind speed value of the fan in the heating water boiler.

[0051] S140. Adjust the speed of the fan based on the current wind speed value and the standard wind speed value of the fan under the calibrated working condition, so that the working state of the heating water boiler is at an optimal air-fuel ratio.

[0052] Among them, the air-fuel ratio is the ratio of the air mass to the fuel mass in the combustible mixed air of the heating water boiler when it is working. Theoretically, the minimum number of grams of air required for complete combustion of each gram of fuel is the theoretical air-fuel ratio, that is, the optimal air-fuel ratio. When the air-fuel ratio is less than the optimal air-fuel ratio, the combustible mixed air contains less air and more fuel. At this time, the combustion of the heating water boiler is incomplete, and it is easy to produce condensed water and excessive flue gas emissions; when the air-fuel ratio is greater than the optimal air-fuel ratio, the combustible mixed air contains more air and less fuel. At this time, the combustion of the heating water boiler is complete, but the heat brought out by the exhaust gas is high, resulting in low combustion efficiency.

[0053] like Figure 2 The figure shows a schematic diagram of the PQ curve of the heating water boiler at different air-fuel ratios. The horizontal axis Q of the PQ curve in the figure represents the gas flow rate, the vertical axis P represents the wind pressure of the fan, and the curve L4 represents the resistivity line of the heating water boiler, which is used to represent the physical quantity of the resistance characteristic of the component in the heating water boiler. The resistivity lines of the same model of heating water boilers are consistent. Curve L0 indicates that the heating water boiler operates at the optimal air-fuel ratio, the air-fuel ratio corresponding to the curve L1 is greater than the optimal air-fuel ratio, and the air-fuel ratio corresponding to the curve L2 is less than the optimal air-fuel ratio. The figure marks a, b and c refer to the corresponding working points of the same model of heating water boiler at different air-fuel ratios. The figure mark a is the working point of the heating water boiler of this model at the optimal air-fuel ratio, the figure mark b is the working point of the heating water boiler of this model when the air-fuel ratio is greater than the optimal air-fuel ratio, and the figure mark c is the working point of the heating water boiler of this model when the air-fuel ratio is less than the optimal air-fuel ratio.

[0054] The standard wind speed value is the wind speed value of the wind speed in the heating water boiler detected under the calibration conditions (that is, the operating state of the heating water boiler is the standard PQ curve) when the heating water boiler is debugged at the factory. It should be noted that when adjusting the fan speed of the heating water boiler, the current wind speed value and the standard wind speed value of the fan in the heating water boiler need to be measured under the unified calibration conditions.

[0055] Specifically, the speed of the fan is adjusted based on the current wind speed value and the standard wind speed value of the fan under calibrated conditions, including: determining the current speed of the fan; determining the adjustment coefficient of the speed of the fan according to the current wind speed value and the standard wind speed value; adjusting the current speed based on the adjustment coefficient to obtain the target speed, so that the standard wind speed value can be reached when the fan operates at the target speed under the calibrated conditions.

[0056] The value of the adjustment coefficient is the standard wind speed value of the fan divided by the current wind speed value, that is, the standard speed of the fan divided by the current speed. The standard speed is the fan speed when the standard wind speed value is generated. Preferably, the adjustment coefficient is configured during the production and commissioning of the heating hot water boiler, and the adjustment coefficient is set to 1 during production and commissioning. The value of the target speed is the current speed of the fan multiplied by the adjustment coefficient, and the target speed of the fan is calculated based on this, so as to adjust the speed of the fan.

[0057] In an embodiment of the present application, when the current wind speed value of the fan in the heating hot water boiler after running for a preset time under the calibrated working conditions is obtained, the current wind speed value and the standard wind speed value are judged. If the current wind speed value is less than the standard wind speed value, the microcontroller determines that the value of the adjustment coefficient is greater than 1. At this time, the current speed of the fan is less than the standard speed of the fan, and the adjustment coefficient of the fan speed is the standard wind speed value of the fan divided by the current wind speed value; if the current wind speed value is less than the standard wind speed value, the heating hot water boiler determines that the value of the adjustment coefficient is less than 1. At this time, the current speed of the fan is greater than the standard speed of the fan, and the adjustment coefficient of the fan speed is the standard wind speed value of the fan divided by the current wind speed value; if the current wind speed value is equal to the standard wind speed value, the heating hot water boiler determines that the value of the adjustment coefficient is equal to 1. At this time, the current speed of the fan is equal to the standard speed of the fan, that is, there is no need to adjust the speed of the fan.

[0058] Furthermore, after determining the adjustment coefficient of the fan speed according to the current wind speed value and the standard wind speed value, it also includes: during the production and commissioning of the heating water boiler, pre-configuring a preset value interval for the adjustment coefficient, and storing the preset value interval in a preset storage unit of the microcontroller. When the adjustment coefficient is determined based on the current wind speed value and the standard wind speed value, the microcontroller determines whether the adjustment coefficient is within the preset value interval; if it is within the preset value interval, the operation of adjusting the current speed based on the adjustment coefficient to obtain the target speed is performed; if it is not within the preset value interval, the square root operation is performed on the adjustment coefficient, the operation result is used as the new adjustment coefficient, and the current speed is adjusted based on the new adjustment coefficient to obtain the target speed.

[0059] Optionally, the preset value interval of the adjustment coefficient is [0.5, 1.5]. Preferably, the preset value interval of the adjustment coefficient is [0.85, 1.15].

[0060] Exemplarily, after determining the current speed of the fan according to the current wind speed value of the fan, and determining the value of the adjustment coefficient according to the standard wind speed value and the current wind speed value of the fan, it is determined whether the adjustment coefficient is within the preset value range of the adjustment coefficient. If the adjustment coefficient is within the preset value range, firstly, the value of the target speed is calculated based on the adjustment coefficient, that is, the current speed of the fan is multiplied by the adjustment coefficient, and then the heating water boiler starts to adjust the current speed of the fan to the target speed based on the calculated value of the target speed, so that the fan can reach the standard wind speed value when running at the target speed under the calibration conditions; if the adjustment coefficient is not within the preset value range, firstly, the square root operation is performed on the adjustment coefficient to obtain a new adjustment coefficient, so that the new adjustment coefficient is within the preset value range, and then the value of the target speed is calculated based on the new adjustment coefficient, that is, the current speed of the fan is multiplied by the new adjustment coefficient, and finally the heating water boiler starts to adjust the current speed of the fan to the target speed based on the calculated value of the target speed, so that the fan can reach the standard wind speed value when running at the target speed under the calibration conditions.

[0061] The technical solution provided in this embodiment generates a prompt message for calibrating the wind speed of the fan in the heating hot water boiler when it is detected that the heating hot water boiler is successfully installed; receives a confirmation operation for the prompt message, and controls the heating hot water boiler to operate for a preset time under the calibrated working conditions; after the preset time, obtains the current wind speed value of the fan; and adjusts the speed of the fan based on the current wind speed value and the standard wind speed value of the fan under the calibrated working conditions, so that the working state of the heating hot water boiler is at an optimal air-fuel ratio. When the present application detects that the heating water boiler is successfully installed, the microcontroller immediately generates a prompt message for prompting the verification of the fan wind speed. At this time, the user or the installer can confirm or cancel the prompt message displayed on the heating water boiler display screen or the smart terminal. Then the microcontroller can receive the user's or the installer's operation on the prompt message. When the operation is a confirmation operation, the heating water boiler is controlled to run for a preset time under the calibration conditions. After running for the preset time, the current wind speed value of the fan in the heating water boiler is obtained. Finally, based on the obtained current wind speed value and the standard wind speed value of the fan under the calibration conditions, the fan speed is adjusted to make the working state of the heating water boiler at the optimal air-fuel ratio. Execution of the present application solution can keep the air-fuel ratio of the heating water boiler constant and in the working state of the optimal air-fuel ratio, improve the combustion efficiency of the heating water boiler, and thus make the heating water boiler meet the exhaust gas emission standards.

[0062] In a specific application embodiment, when the microcontroller of the heating water heater detects that the heating water heater has been successfully installed, the climate detection component or positioning component configured inside the heating water heater detects the environmental information such as the altitude and temperature of the production site and the installation site of the heating water heater, and then compares whether the environmental information of the production site and the installation site are consistent. If they are inconsistent, it will cause the change of the wind speed of the fan when the heating water heater is working. At this time, the microcontroller generates a prompt message for prompting the verification of the wind speed of the fan, prompting the user or the installer to adjust the wind speed of the fan. At this time, the prompt information can be displayed on the display screen of the heating water heater or on the smart terminal connected to the heating water heater, and the confirmation button and the cancel button are displayed. At this time, the user or the installer can operate the confirmation button and the cancel button on the display screen of the heating water heater or on the smart terminal according to the actual use requirements. After the user or the installer clicks the confirmation button, the microcontroller of the heating water heater receives the confirmation operation of the user or the installer for the prompt information, and controls the heating water heater to run for a preset time under the calibration condition. After the heating water boiler runs for a preset time, the microcontroller obtains the current wind speed value of the fan. After obtaining the current wind speed value of the fan, the microcontroller determines the current speed of the fan, and then determines the adjustment coefficient of the speed of the fan based on the current wind speed value and the standard wind speed value, that is, if the current wind speed value is less than the standard wind speed value, the value of the adjustment coefficient is determined to be greater than 1, and the current speed of the fan is less than the standard speed of the fan; if the current wind speed value is less than the standard wind speed value, the value of the adjustment coefficient is determined to be less than 1, and the current speed of the fan is greater than the standard speed of the fan; if the current wind speed value is equal to the standard wind speed value, the value of the adjustment coefficient is determined to be equal to 1, and the current speed of the fan is equal to the standard speed of the fan. After determining the value of the adjustment coefficient, the microcontroller of the heating water boiler begins to determine whether the adjustment coefficient is within a preset value range, and this preset value range can be selected as [0.5, 1.5], and the preset value range is preferably [0.85, 1.15]. If the adjustment coefficient is within the preset numerical range, the microcontroller starts to calculate the value of the target speed based on the adjustment coefficient, that is, the current speed of the fan is multiplied by the adjustment coefficient, and the current speed of the fan is adjusted to the target speed based on the calculated target speed, so that the fan can reach the standard wind speed value when running at the target speed under the calibrated working conditions; if the adjustment coefficient is not within the preset numerical range, the microcontroller of the heating hot water boiler performs a square root operation on the adjustment coefficient to obtain a new adjustment coefficient, so that the new adjustment coefficient is within the preset numerical range, and then calculates the target speed based on the new adjustment coefficient, that is, the current speed of the fan is multiplied by the new adjustment coefficient, and the current speed of the fan is adjusted to the target speed according to the calculated target speed, so that the fan can reach the standard wind speed value when running at the target speed under the calibrated working conditions.
