Description

Technical Field

[0001] This invention relates to a water heater and its control method, system, and storage medium. Background Technology

[0002] A gas water heater, also known as a gas-fired water boiler, is a gas appliance that uses gas as fuel and heats water by transferring heat to cold water flowing through a heat exchanger. However, during the heating process, water heaters generate significant noise due to the rotation of the fan, affecting the user experience. Current technology attempts to reduce noise by increasing fan speed and accelerating exhaust emissions. However, these methods only shorten the duration of noise generation and do not reduce the decibel level, thus still impacting the user experience. Summary of the Invention

[0003] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies that reduce noise impact on users by increasing fan speed and accelerating water heater exhaust emissions. However, these methods only shorten the duration of noise generation and do not reduce the decibel level, still affecting the user experience. This invention provides a water heater and its control method, system, and storage medium.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This invention discloses a method for controlling the noise level of a water heater, the method comprising:

[0006] Calculate the demand load of the water heater;

[0007] Determine whether the demand load reaches the rated load of the water heater. If yes, control the water heater to operate under the first operating parameter corresponding to the demand load. If no, increase the combustion level to obtain a second operating parameter with a value lower than the first operating parameter, and control the water heater to operate under the second operating parameter. The first and second operating parameters are parameters related to the operation of the fan and / or the flame.

[0008] In this solution, by increasing the combustion setting, the combustion points of the water heater can be dispersed, thereby reducing the speed of the fans at each combustion point and lowering the overall noise generated by the fan rotation. This, in turn, reduces both fan noise and combustion noise. In other words, by employing this control method, the noise level of the fan rotation is reduced to a decibel level, thus fundamentally reducing the noise generated by the burner and improving the user experience.

[0009] Preferably, the step of obtaining a second operating parameter with a value lower than the first operating parameter includes:

[0010] Based on the ratio between the combustion gear before and after the increase, the first operating parameter is reduced to obtain the second operating parameter.

[0011] In this scheme, the above-mentioned control method is adopted, which improves the accuracy of parameter adjustment.

[0012] Preferably, the combustion setting includes a gas outlet area, and the step of increasing the combustion setting includes increasing the gas outlet area.

[0013] In this solution, the above-mentioned control method is adopted. By increasing the area of ​​the gas outlet, the combustion points of the water heater can be dispersed, thereby reducing the speed of the fans at each combustion point, and thus reducing fan noise and combustion noise.

[0014] Preferably, the step of reducing the first operating parameter to obtain the second operating parameter based on the ratio between the combustion gear before and after the increase includes:

[0015] Substituting the combustion gear before and after the increase into k1=1-(P) 提高后 -P 提高前 ) / P 提高后 The first preset coefficient is obtained from 100%, where k1 is the first preset coefficient; P 提高后 The number corresponding to the upgraded combustion gear; P 提高前 The number corresponding to the previous combustion gear;

[0016] The second operating parameters are obtained based on the first operating parameters and the first preset coefficient.

[0017] In this scheme, the above control method is adopted. After gear switching, the first preset coefficient can be re-adapted, so that the second operating parameter can be obtained based on the first operating parameter and the first preset coefficient, thereby improving the accuracy of calculation and adaptation.

[0018] Preferably, after the step of controlling the water heater to operate under the second operating parameter, the silent control method further includes:

[0019] Detect the actual temperature of the water after heating;

[0020] Determine whether the deviation between the actual temperature and the set temperature meets the preset requirements. If yes, no operation is performed; otherwise, the proportional valve current is reduced.

[0021] In this solution, the aforementioned control method allows the actual temperature to reach the preset temperature more accurately. Furthermore, this method reduces the heat storage capacity of the heat exchanger, preventing residual heat from continuing to heat the water heater after a water outage, thus preventing temperature rise during water outages.

[0022] Preferably, the steps to reduce the proportional valve current include:

[0023] Substituting the proportional valve current before reduction into I3=k2 The reduced proportional valve current is obtained from I2; where I3 is the reduced proportional valve current; I2 is the original proportional valve current; k2 is a coefficient, and k2 1.

[0024] In this scheme, by adopting the above control method, the reduced proportional valve current can be calculated based on the proportional valve current before cooling and the coefficient, thereby improving the accuracy of the calculation of the reduced proportional valve current. The coefficient is related to the type of proportional valve.

[0025] Preferably, the operating parameters include fan speed and / or proportional valve current.

[0026] In this scheme, by adopting the above control method, the fan speed and proportional valve current can adjust the oxygen supply and gas supply during the combustion of the water heater, thereby changing the combustion of the water heater and thus changing the operating parameters of the burner.

[0027] Preferably, the step of calculating the demand load of the water heater includes:

[0028] Detect the inlet water temperature and water flow rate;

[0029] The required load is obtained based on the inlet water temperature, the water flow rate, and the set temperature.

[0030] In this scheme, the above control method can solve the demand load and facilitate the subsequent determination of whether to adjust the gear based on the demand load, thus improving the accuracy of the adjustment.

[0031] Preferably, the step of obtaining the demand load based on the inlet water temperature, the water flow rate, and the set temperature includes:

[0032] Substituting the inlet water temperature, the set temperature, and the water flow rate into Q=(T) 设定 -T 进水 ) The demand load is obtained from L; where Q is the demand load; T 设定 The set temperature; T 进水 The inlet water temperature is L; the water flow rate is L.

[0033] In this scheme, the above control method can accurately calculate the demand load based on the actual inlet water temperature and water flow rate, thus improving the accuracy of the calculation.

[0034] Preferably, the set temperature is a fixed value, or the set temperature is a value that changes over time or with a variable.

[0035] This invention also discloses a control method for a water heater, including a conventional control method for a water heater, and further including the silent control method for a water heater as described in any one of the above claims, wherein the control method for the water heater includes:

[0036] The user can choose to execute either the conventional control method or the silent control method of the water heater according to their operation instructions.

[0037] In this solution, the silent control method can disperse the combustion points of the water heater by increasing the combustion setting, thereby reducing the speed of the fan at each combustion point and lowering the overall noise generated by the fan rotation. This, in turn, reduces both fan noise and combustion noise. In other words, by adopting the above control method, the noise level of the fan rotation is reduced, thus fundamentally reducing the noise generated by the burner and improving the user experience.

[0038] This invention further discloses a control system for a water heater, used to execute the silent control method for the water heater described above, the control system comprising:

[0039] The calculation module is used to calculate the demand load;

[0040] The judgment module is used to determine whether the demand load has reached the rated load;

[0041] The execution module is used to control the water heater to operate under the first combustion parameter corresponding to the demand load, increase the combustion level, decrease the second combustion parameter corresponding to the demand load, and control the water heater to operate under the second combustion parameter.

[0042] The present invention also discloses a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the silent control method for a water heater as described above.

[0043] The present invention further discloses a water heater, including a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that the processor executes the computer program to implement the silent control method of the water heater as described above.

[0044] The positive and progressive effects of this invention are as follows:

[0045] By increasing the combustion setting, the combustion points of the water heater can be dispersed, thereby reducing the speed of the fans at each combustion point. This reduces the overall noise generated by the fan rotation, and consequently, reduces both fan noise and combustion noise. In other words, by adopting this control method, the decibel level of the fan rotation noise is reduced, which fundamentally reduces the noise generated by the burner combustion, thus improving the user experience.

[0052] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0053] Example 1

[0054] like Figure 1 and Figure 4 As shown, this embodiment provides a method for controlling the noise level of a water heater, and the method includes:

[0055] Step S1: Calculate the demand load of the water heater; specifically, the demand load of the water heater represents the amount of heat that the water heater can release per unit time. The larger the value, the greater the heating capacity of the water heater, which enables the water heater to heat more water to the required temperature in a shorter time.

[0056] Step S2: Determine whether the demand load reaches the rated load of the water heater. If yes, control the water heater to operate under the first operating parameter corresponding to the demand load; if not, increase the combustion setting to obtain a second operating parameter lower than the first operating parameter, and control the water heater to operate under the second operating parameter. The first and second operating parameters relate to the operation of the fan and / or the flame. Specifically, by increasing the combustion setting, the combustion points of the water heater can be dispersed, thereby reducing the fan speed at each combustion point, reducing the overall noise generated by the fan rotation, and thus reducing fan noise and combustion noise. In other words, by adopting the above control method, the noise level of the fan rotation is reduced, thereby fundamentally reducing the noise generated by the burner combustion and improving the user experience.

[0057] In this embodiment, (T 设定 -T 进水 )×L / k3>P, where T 设定 The set temperature; T 进水 Let s be the inlet water temperature; L be the water flow rate; k3 be a coefficient; and P be the rated load deviation. In other words, in this embodiment, by judging (T... 设定 -T 进水 The load deviation calculated by k3 × L / k3 is used to determine whether the required load has reached the rated load of the water heater. In this embodiment, k3 is set to 25 and P is set to 14. In other embodiments, the values ​​of k3 and P can be adjusted according to actual needs, and no specific values ​​are limited here.

[0058] Step S2 involves obtaining a second operating parameter whose value is lower than the first operating parameter, including:

[0059] Step S21: Based on the ratio between the combustion gear before and after the increase, reduce the first operating parameter to obtain the second operating parameter. This control method improves the accuracy of parameter adjustment.

[0060] In practical use, it is preferable to use the upgraded combustion setting as the burner's maximum setting, and the difference between the original and upgraded combustion settings should be at least two settings. Furthermore, the maximum setting number varies depending on the type of water heater. Therefore, you can substitute the corresponding maximum setting number for different types of water heaters.

[0061] In this embodiment, the first operating parameter and the second operating parameter include the fan speed and the proportional valve current.

[0062] The combustion setting includes the gas outlet area, and increasing the combustion setting includes increasing the gas outlet area. In other words, in this embodiment, by increasing the gas outlet area, the combustion points of the water heater can be dispersed, thereby reducing the fan speed at each combustion point and thus reducing fan noise and combustion noise.

[0063] Please see Figure 2 To understand this, step S21, which involves reducing the first operating parameter to obtain the second operating parameter based on the ratio between the combustion gear before and after the increase, includes:

[0064] Step S211: Substitute the combustion gear before and after the increase into k1=1-(P) 提高后 -P 提高前 ) / P 提高后 The first preset coefficient is obtained from 100%, where k1 is the first preset coefficient; P 提高后 The number corresponding to the upgraded combustion gear; P 提高前 The number corresponding to the previous combustion gear;

[0065] Taking the combustion gear before the upgrade as gear 1 and the combustion gear after the upgrade as gear 3 as an example, the solution for k1 is: k1 = 1 - (3 - 1) / 3 × 100% = 66.7%. In this embodiment, the solution process for the first preset coefficient is adaptively solved using the combustion gear before the upgrade as gear 1 and the combustion gear after the upgrade as gear 3 as an example. In other embodiments, the combustion gear before and after the upgrade can be set according to actual needs, and are not limited here.

[0066] Step S212: Obtain the second operating parameters based on the first operating parameters and the first preset coefficient. Specifically, after gear shifting, the first preset coefficient can be re-adapted, thereby obtaining the second operating parameters based on the first operating parameters and the first preset coefficient, thus improving the accuracy of the calculation.

[0067] In practical application, the first and second operating parameters can be implemented in several ways: Firstly, the operating parameters include fan speed; secondly, the operating parameters include proportional valve current; and thirdly, the operating parameters include both fan speed and proportional valve current. Preferably, the operating parameters include both fan speed and proportional valve current. Using the above control methods, the fan speed and proportional valve current can adjust the oxygen supply and gas supply during water heater combustion, thereby changing the combustion conditions of the water heater and consequently altering the burner's operating parameters. Specifically, the higher the fan speed and the higher the proportional valve current, the greater the oxygen supply and gas supply to the water heater, resulting in more complete combustion.

[0068] In this embodiment, the first operating parameters include the fan speed and the proportional valve current. After the first preset coefficient is solved in step S211, the fan speed and proportional valve current under the second operating parameters can be obtained based on the preset coefficient and the fan speed and proportional valve current under the first operating parameters, so that the water heater can continue to burn under the fan speed and proportional valve current under the second operating parameters.

[0069] After step S2, the mute control method further includes:

[0070] Step S201: Detect the actual temperature of the water after heating; specifically, the actual temperature of the water after heating can be detected by a temperature sensor.

[0071] Step S202: Determine whether the deviation between the actual temperature and the set temperature meets the preset requirements. If yes, no operation is performed; otherwise, the proportional valve current is reduced. This control method allows the actual temperature to reach the preset temperature more accurately. Furthermore, this method reduces the heat exchanger's heat storage, preventing residual heat from continuing to heat the water heater after a water outage. This prevents the water heater from experiencing a temperature rise during water outages, thus preventing users from being scalded by hot water when the tap is first turned on, improving user safety.

[0072] In this embodiment, the absolute value of the difference between the actual temperature and the set temperature is greater than 5 to determine whether to reduce the proportional valve current. In other words, in this embodiment, the difference between the actual temperature and the set temperature is used to determine whether the preset requirement is met. In this embodiment, the preset requirement is set to 5. In other embodiments, the actual temperature and the set temperature can also be used as a ratio to determine whether the preset requirement is met, and the value of the preset requirement can be adjusted according to actual needs; this is not limited here.

[0073] Step S202 includes:

[0074] Substituting the proportional valve current before reduction into I3=k2 The reduced proportional valve current is obtained from I2; where I3 is the reduced proportional valve current; I2 is the original proportional valve current; and k2 is a coefficient, and k2 1. By adopting the above control method, the reduced proportional valve current can be calculated based on the proportional valve current before cooling and the coefficient, thereby improving the accuracy of the calculation of the reduced proportional valve current. The coefficient is related to the type of proportional valve, and its coefficient may change if the type of proportional valve is changed.

[0075] In practical use, the gear position and the gas outlet area are positively correlated.

[0076] In this embodiment, k2 is 80%. In other embodiments, the size of k2 can be selected according to actual needs, and is not limited here.

[0077] like Figure 3 As shown, step S1 includes:

[0078] Step S11: Detect the inlet water temperature and water flow rate; In this embodiment, the inlet water temperature can be detected by a temperature sensor installed on the pipe, and the water flow rate can be detected by a flow sensor installed on the pipe.

[0079] Step S12: Obtain the demand load based on the inlet water temperature, water flow rate, and set temperature. Using the above control method, the demand load can be solved, and it is convenient to determine whether to adjust the speed range based on the demand load later, thereby improving the accuracy of the adjustment.

[0080] In practical use, the set temperature can be entered in a pop-up input box on the water heater, or it can be a target parameter obtained internally by the water heater as the demand load. Furthermore, the set temperature can be a fixed value, or it can be a value that changes over time or with other variables. The variables mentioned above can be selected according to actual needs; no specific representation of the variables is limited here.

[0081] Step S12 includes:

[0082] Substitute the inlet water temperature, set temperature, and water flow rate into Q=(T) 设定 -T 进水 ) The demand load is obtained from L; where Q is the demand load; T 设定 The set temperature; T 进水 L represents the inlet water temperature; L represents the water flow rate. Using the above control method, the required load can be accurately calculated based on the actual inlet water temperature and water flow rate, improving the accuracy of the calculation.

[0083] Example 2

[0084] This embodiment provides a water heater control method, including a conventional water heater control method and the silent water heater control method described in Embodiment 1. The water heater control method includes:

[0085] Based on the user's instructions, the water heater can be controlled using either its standard operating procedure or its silent operation mode. Specifically, in silent mode, the combustion level can be increased to disperse the combustion points, thereby reducing the fan speed at each combustion point and lowering the overall fan noise. In other words, this control method reduces the decibel level of the fan rotation, fundamentally reducing the noise generated by the burner and improving the user experience.

[0086] In this embodiment, the user's command can be made by pressing an input button, or by inputting time parameters and control mode on the water heater's operating interface. When the current time reaches the input time parameter, the water heater is controlled to select the desired control mode. Furthermore, the conventional control method for water heaters mentioned above refers to existing water heater control methods in the prior art.

[0087] Example 3

[0088] like Figure 5 As shown, this embodiment provides a control system for a water heater, used to execute the silent control method for the water heater in Embodiment 1. The control system includes:

[0089] Calculation module 1 is used to calculate the demand load; specifically, the demand load of the water heater represents the amount of heat that the water heater can release per unit time, and if the value is greater than a certain threshold, it indicates that the water heater has a greater heating capacity, thus enabling the water heater to heat more water to the required temperature in a shorter time.

[0090] In this embodiment, the inlet water temperature can be detected by a temperature sensor installed on the pipeline, and the water flow rate can be detected by a flow sensor installed on the pipeline. The required load is obtained based on the inlet water temperature, water flow rate, and set temperature. Specifically, the inlet water temperature, set temperature, and water flow rate are substituted into Q=(T 设定 -T 进水 ) The demand load is obtained from L; where Q is the demand load; T 设定 The set temperature; T 进水 L represents the inlet water temperature; L represents the water flow rate. Using the above control method, the required load can be accurately calculated based on the actual inlet water temperature and water flow rate, improving the accuracy of the calculation.

[0091] The judgment module 2 is used to determine whether the demand load has reached the rated load; specifically, it can determine whether the demand load has reached the rated load of the water heater, thereby controlling the burner to work under the first operating parameters corresponding to the demand load, or to increase the combustion level.

[0092] In practical use, the set temperature can be entered in a pop-up input box on the water heater, or it can be a target parameter obtained internally by the water heater as the demand load. Furthermore, the set temperature can be a fixed value, or it can be a value that changes over time or with other variables. The variables mentioned above can be selected according to actual needs; no specific representation of the variables is limited here.

[0093] Execution module 3 is used to control the water heater to operate under the first combustion parameter corresponding to the demand load, increase the combustion level, decrease the second combustion parameter corresponding to the demand load, and control the water heater to operate under the second combustion parameter. If the demand load reaches the rated load, the water heater is controlled to operate under the first operating parameter corresponding to the rated load; if the demand load does not reach the rated load, the water heater is controlled to operate under the second operating parameter, which is lower than the first operating parameter. By increasing the combustion level, the combustion points of the water heater can be dispersed, thereby reducing the speed of the fan at each combustion point, reducing the noise generated by the overall fan rotation, and thus reducing fan noise and combustion noise. In other words, by adopting the above control method, the noise level of the fan rotation is reduced, thereby fundamentally reducing the noise generated by the burner combustion and improving the user experience.

[0094] In this embodiment, (T 设定 -T 进水 )×L / k3>P, where T 设定 The set temperature; T 进水 Where T is the inlet water temperature; L is the water flow rate; k3 is a coefficient; and P is the rated load deviation. In other words, this embodiment determines (T) by... 设定 -T 进水 The load deviation calculated by k3 × L / k3 is used to determine whether the required load has reached the rated load of the water heater. In this embodiment, k3 is set to 25 and P is set to 14. In other embodiments, the values ​​of k3 and P can be adjusted according to actual needs, and no specific values ​​are limited here.
