In the event of flameout, if the boiler is detected to start water use again during the first continuous period, the burner can quickly switch to normal combustion without restarting, reducing water temperature fluctuations. If the boiler is confirmed to be in summer mode, the fan enters a self-cleaning state and maintains this state until the end of the second continuous period. If the boiler is detected to start water use again during the second continuous period, the burner is instructed to quickly enter normal combustion without waiting for the fan to complete its self-cleaning process and exit self-cleaning mode.

[0033] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0035] It is understood that, and should be noted, the terms “first” and “second” in this application are used to distinguish different objects, rather than to describe a specific order.

[0036] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0037] Currently, when using domestic hot water in existing boilers, after the initial water use, a short period of time is required before starting secondary water use. Because the boiler's control mode starts operating upon receiving a water flow signal from the bathroom, it has already entered a pre-cleaning self-check state before ignition. It needs to wait for the boiler to complete the corresponding cleaning instructions and exit the pre-cleaning self-check state before entering the combustion state. During this pre-cleaning self-check period, cold tap water enters the boiler without being heated, and the pipes remain hot after the initial water use. As a result, the water outlet pipe experiences a fluctuating temperature, first hot water, then cold water, and then hot water again, significantly impacting the user's water experience.

[0038] To address these issues, existing technologies often involve adding a water tank to heat or buffer the water stored in external pipes. This reduces the frequency of start-ups and shutdowns of the gas boiler and minimizes fluctuations in outlet water temperature, thereby saving gas consumption and improving the user's water experience. However, adding a water tank increases the overall size of the boiler, and the tank also causes heat loss, resulting in higher operating costs for users.

[0039] This application improves the user's water experience by quickly switching to combustion mode when the heating boiler is in different usage modes and there is a need for secondary water use in a short period of time after the current water use is completed. This avoids large fluctuations in water temperature and sudden changes in water temperature. In addition, this application does not require changes to the existing combustion structure of the heating boiler and does not increase the overall cost. It improves the water experience by adjusting the control method.

[0040] The control method for the heating furnace provided in this application embodiment can be applied to, for example... Figure 1 The heating boiler shown is equipped with a control unit 102 connected to both the burner 104 and the fan 106. The control unit 102 responds to the heating boiler completing its current water usage and determines the corresponding operating mode. If the heating boiler is detected to be in winter mode, and the burner 104 is in a low-power combustion state, the control unit 102 detects that the heating boiler will start the next water usage within a first continuous period and outputs a heating command to the burner 104. If the heating boiler is detected to be in summer mode, and the fan 106 is in a self-cleaning state, the control unit 102 detects that the heating boiler will start the next water usage within a first continuous period and outputs a heating command to the burner 104. The control unit 102 can be an MCU (Microcontroller Unit) or a CPU (Central Processing Unit). The burner 104 can refer to the device in the heating boiler used to perform the combustion operation. It should be noted that the heating boiler may also include other modes besides winter and summer modes, which are not limited in this application. The ambient temperature corresponding to the winter mode is lower than that of the summer mode.

[0041] In one embodiment, such as Figure 2 As shown, a control method for a heating boiler is provided, which is applied to... Figure 1 Taking a heating boiler as an example, the following steps are included:

[0042] S202, in response to the heating boiler completing this water usage, determine the corresponding usage mode of the heating boiler.

[0043] The usage mode of the heating boiler can refer to the control mode of the heating boiler.

[0044] Specifically, the control unit responds to the heating boiler completing the current water usage and detects the operating mode of the heating boiler.

[0045] S204, in response to the usage mode being winter mode, outputs a heating command, which instructs the burner to enter a low-power combustion state and maintain the low-power combustion state for a first duration period; if it is detected that the heating boiler starts the next water supply during the first duration period, a heating command is output.

[0046] Among them, the winter mode can refer to the treatment mode with heating and bathroom functions; it should be noted that the winter mode is often used when the temperature is low.

[0047] The burner includes a fire bar capable of segmented combustion; the first duration period can be set according to actual conditions.

[0048] It should be noted that the heating boiler includes a device that can detect water flow rate in order to detect the user's water demand. The device that can detect water flow rate can be a water flow sensor.

[0049] Specifically, when the control unit detects that the usage mode is winter mode, it outputs a heating command to the burner, which then enters a low-power combustion state and maintains this state for a first continuous period to achieve the heating function of the boiler. If the boiler's water flow sensor detects that the user has a secondary water demand during the first continuous period, the control unit outputs a heating command, and the burner quickly switches to normal combustion mode after receiving the heating command to achieve the bathroom function of the boiler.

[0050] In one embodiment, the heating boiler further includes terminal radiators connected to the control unit;

[0051] The low-power combustion state is the state corresponding to the burner burning at its minimum power; where the minimum power is less than or equal to the heat dissipation power of the end radiator.

[0052] Specifically, low-power combustion state refers to the state in which the burner uses the fewest number of burner segments and maintains combustion under the lowest load (minimum power). At this time, the power input of the heating boiler is low, which can match the heat dissipation capacity of the terminal to ensure that the heating boiler maintains combustion state.

[0053] In some examples, the power input of the boiler combustion can match the heat dissipation capacity of the terminal radiator. That is, when the heat dissipation power of the radiator at the end of the boiler is 15kW, the boiler is in a low-power combustion state. When the combustion input power is only 5kW, it is significantly less than the power required by the radiator. Therefore, combustion will continue and it is not easy for the system water to overheat and cause flameout. Flameout due to system water overheating can refer to the situation where the combustion input power is greater than the heat dissipation power of the terminal radiator, the system water will slowly overheat and eventually reach the conditions for stopping combustion, and the burner will stop burning.

[0054] In this embodiment, after the heating boiler completes the current water usage, the control unit outputs a heating command to instruct the burner to switch to a low-power combustion state, ensuring continuous combustion of the burner and preventing the heating water from overheating and causing flameout. This allows the burner to quickly switch back to normal combustion state without restarting when the heating boiler is detected to start the next water usage within the first continuous period, reducing water temperature fluctuations and improving the user's water usage experience.

[0055] In one embodiment, the method further includes:

[0056] If the next water supply is not initiated within the first continuous period, the burner operation is controlled by PID (Proportional-Integral-Derivative) control based on the target heating temperature.

[0057] The target heating temperature can be set according to the actual situation.

[0058] Specifically, if the water flow sensor of the heating boiler does not detect a user's secondary water demand during the first continuous period, the control unit obtains the target heating temperature and controls the operation of the burner through PID control based on the target heating temperature.

[0059] Furthermore, the control unit can control the burner's operation through PID control, which may include: the control unit adjusting the power input of the combustion; when the heating outlet water temperature is greater than or equal to 5 degrees higher than the target heating temperature, the burner will stop combustion, the water pump will continue to run, and when the heating return water temperature is less than or equal to 10 degrees lower than the target heating temperature after the heating water dissipates heat through the heating terminal, the heating boiler will restart heating.

[0060] In this embodiment of the application, if the next water use is not initiated within the first continuous period, the control unit controls the operation of the burner through PID control based on the heating target temperature, thereby maintaining the normal operation of the heating boiler.

[0061] S206, in response to the usage mode being summer mode, outputs a cleaning command, which instructs the fan to enter a self-cleaning state and maintain the self-cleaning state for the second continuous period; if it is detected that the heating boiler starts the next water use during the second continuous period, a heating command is output.

[0062] The heating command is used to instruct the burner to enter normal combustion mode; the ambient temperature corresponding to the winter mode is lower than that corresponding to the summer mode.

[0063] Among them, the summer mode can refer to the mode with bathroom functions; it should be noted that the summer mode is often used when the temperature is high.

[0064] Specifically, when the control unit detects that the usage mode is summer mode, the burner stops burning, the control unit outputs a cleaning command to the fan, the fan enters a self-cleaning state, and maintains the self-cleaning state for the second continuous period; if the water flow sensor of the heating boiler detects that the user has a secondary water demand during the second continuous period, the control unit outputs a heating command, and the burner quickly switches to normal combustion state after receiving the heating command to realize the bathroom function of the heating boiler.

[0065] In one embodiment, the second duration includes a pause time, a first cleaning time, and a second cleaning time; the self-cleaning state includes:

[0066] The fan enters the cleaning state. If the fan maintains the cleaning state until the end of the first cleaning time, the fan enters the stop state. If the fan remains in the stop state until the end of the pause time, the fan enters the cleaning state and maintains the cleaning state until the end of the second cleaning time.

[0067] The first cleaning time, pause time, and second cleaning time can all be set according to the actual situation.

[0068] It should be noted that the cleaning status of the fan can refer to the front cleaning status or the rear cleaning status; a pause time is set to prevent the air pressure switch (a protection device in the heating boiler) from malfunctioning, and the pause is used to allow the air pressure switch to reset before restarting.

[0069] Specifically, if the control unit instructs the fan to maintain the cleaning state until the first cleaning time ends, it instructs the fan to enter the stop state. If the fan remains in the stop state until the pause time ends, the control unit instructs the fan to enter the cleaning state again and maintain the cleaning state until the second cleaning time ends.

[0070] In this embodiment, after the heating boiler completes its water usage, the control unit outputs a cleaning command to instruct the fan to enter a self-cleaning state. This allows the burner to quickly enter normal combustion state when the heating boiler is detected to start the next water usage within the first continuous period, without waiting for the fan to complete self-cleaning and exit the self-cleaning state. This solves the problem of large water temperature fluctuations that easily occur when there is a secondary water usage demand in the short term after the heating boiler has completed its water usage, and improves the user's water usage experience.

[0071] In some examples, the second duration is determined based on the model of the wind turbine.

[0072] Specifically, the different models of fans result in different times required for each fan to enter and maintain a self-cleaning state.

[0073] In one embodiment, if the next water usage is not initiated during the second continuous period, the fan exits the self-cleaning state and enters the standby state.

[0074] Specifically, if the water flow sensor of the heating boiler does not detect a user's need for secondary water use during the second continuous period, the control unit instructs the fan to exit the self-cleaning state and instructs the heating boiler to enter the standby state.

[0075] In this embodiment of the application, if the next water use is not initiated during the second continuous period, the control unit instructs the fan to exit the self-cleaning state and instructs the heating boiler to enter the standby state, thereby maintaining the normal operation of the heating boiler.

[0076] In one embodiment, when a heating command is output, the burner is controlled by PID control based on the target bathroom temperature.

[0077] The bathroom temperature can be set according to actual needs.

[0078] Specifically, when the heating boiler is in winter mode or summer mode, the control unit outputs a heating command and obtains the target temperature of the bathroom. Based on the target temperature of the bathroom, PID control is performed to ensure rapid water output and that the water temperature remains constant (target temperature of the bathroom). It should be noted that the method of PID control based on the target temperature of the bathroom by the control unit is not limited in this application.

[0079] To facilitate understanding by those skilled in the art, the control method of a heating boiler is explained below with reference to a specific example, such as... Figure 3 As shown, it should be noted that the first continuous period can be 3 to 5 minutes; the first cleaning time is 10 to 30 seconds; the second cleaning time can be 3 to 5 minutes; and the pause time is not limited in this embodiment.

[0080] When the heating boiler operates in winter mode: After the user completes the first bathroom water use, the control unit detects no bathroom water flow through the water flow sensor. The control unit automatically turns on the heating function, outputs a heating command, and forces the burner to switch to the minimum number of burners and the lowest load state to maintain combustion for 3 to 5 minutes (the first continuous period). If the heating boiler water flow sensor detects that the user has a secondary water use demand during the first continuous period, it will directly switch to the bathroom function for heating.

[0081] If the water flow sensor of the heating boiler does not detect water flow within the set time of 3 to 5 minutes (the first continuous period), the control unit determines that the user has no water demand, and the heating boiler will switch to normal operation. That is, it will perform PID control according to the heating target temperature, and the control unit will adjust the input power. When the heating outlet water temperature is greater than or equal to 5 degrees higher than the heating target temperature, the burner will stop burning, and the water pump will continue to run. After the heating water dissipates heat through the heating terminal, when the heating return water temperature is less than or equal to 10 degrees lower than the heating target temperature, the heating boiler will restart heating.

[0082] The boiler operates in summer mode as follows: After the user completes the first bathroom water use, the control unit detects no bathroom water flow through the water flow sensor. The boiler (burner) stops burning, and the fan enters the post-cleaning state and runs for 10-30 seconds (first cleaning time) before stopping. After the air pressure switch resets, the fan re-enters the pre-cleaning state and runs for 3-5 minutes (second cleaning time). During the second continuous period, when the boiler's water flow sensor detects water flow, the boiler will directly enter the ignition and combustion state to heat the bathroom water. The boiler uses PID control based on the target bathroom temperature to ensure rapid and constant temperature.

[0083] If the boiler does not detect any demand for bathroom water during the second continuous period, the fan will stop operating after completing the pre-cleaning state for 3 to 5 minutes (the second cleaning time), and the boiler will enter standby mode.

[0084] In the aforementioned control method for the heating boiler, in response to the completion of the current water usage, if the boiler is in winter mode, the burner enters a low-power combustion state to ensure that the boiler will not overheat and shut down. This ensures that if the boiler is detected to start the next water usage within the first continuous period, the burner can quickly switch to normal combustion without restarting, reducing water temperature fluctuations. If the boiler is detected to be in summer mode, the fan enters a self-cleaning state and maintains this state until the end of the second continuous period. If the boiler is detected to start the next water usage within the second continuous period, the burner is instructed to quickly enter normal combustion without waiting for the fan to complete its self-cleaning and exit the self-cleaning state. This solves the problem of large water temperature fluctuations that can easily occur when there is a secondary water usage demand in the short term after the boiler has completed the current water usage, thus improving the user's water usage experience.
