Of course, they are merely examples and are not intended to limit the present application. Moreover, the present application can repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not indicate a relationship between the various embodiments and / or arrangements discussed.

[0057] Reference Figure 1 , Figure 1 A flowchart of a control method of a gas water heater is provided for the embodiments of the present application. The control method of a gas water heater provided by the embodiments of the present application includes the following steps:

[0058] S101: After the gas water heater is ignited, the actual working voltage of the gas water heater is acquired.

[0059] In the embodiment, the execution subject is a processor in the gas water heater. The gas water heater is a direct-current gas water heater. The gas water heater is connected with a power supply end of the gas water heater, and the specific reference is shown in Figure 4 . The power supply end of the gas water heater is a power adapter or a photovoltaic direct-current micro-grid. The actual working voltage of the gas water heater is actually the voltage on the connection line between the power supply end of the gas water heater and the gas water heater. The power supply end of the gas water heater is used to provide power for the gas water heater. After the gas water heater is ignited, the actual working voltage of the gas water heater can be acquired through the processor in the gas water heater. Continue to refer to Figure 4 , the gas water heater further includes a fan, a water pump and a proportional valve, and the processor in the gas water heater is connected with the fan, the water pump and the proportional valve to control the fan, the water pump and the proportional valve. The current and voltage detection module is arranged in the fan, the water pump and the proportional valve, the current and voltage detection module in the fan is used to detect the working current of the fan, the current and voltage detection module in the water pump is used to detect the working current of the water pump, and the current and voltage detection module in the proportional valve is used to detect the working current of the proportional valve. It should be noted that after the gas water heater is ignited, the gas water heater is controlled by the processor in the gas water heater.

[0060] S102: When it is determined that the power supply end of the gas water heater is abnormal according to the actual working voltage, a target power regulation strategy corresponding to the gas water heater is determined according to the actual working voltage.

[0061] In this embodiment, the abnormality of the power supply end of the gas water heater mainly manifests that the input power of the gas water heater decreases or fluctuates. Since the input power of the gas water heater is the output power of the power supply end of the gas water heater, when the input power of the gas water heater decreases or fluctuates, it indicates that the power supply end of the gas water heater is abnormal. The decrease or fluctuation of the input power of the gas water heater can be obtained by acquiring the actual working voltage of the gas water heater, comparing the actual working voltage of the gas water heater with the rated working voltage of the gas water heater, and determining whether the power supply end of the gas water heater is abnormal. When the power supply end of the gas water heater is abnormal, the gas water heater may be extinguished if it continues to be used, which affects the user experience. Therefore, when it is determined that the power supply end of the gas water heater is abnormal, the abnormality degree of the power supply end of the gas water heater is determined according to the actual working voltage of the gas water heater, and a target power regulation strategy corresponding to the gas water heater is determined according to the abnormality degree of the power supply end of the gas water heater, so as to control the gas water heater according to the target power regulation strategy. The target power regulation strategy is used to control the working current of the fan, the water pump and the proportional valve in the gas water heater, so as to realize the adaptive regulation of the power of the gas water heater.

[0062] S103: The gas water heater is controlled according to the target power regulation strategy.

[0063] In this embodiment, after the target power regulation strategy corresponding to the gas water heater is determined according to the abnormality degree of the power supply end of the gas water heater, the working current of the fan, the water pump and the proportional valve can be controlled according to the working current control mode of the fan, the water pump and the proportional valve indicated in the target power regulation strategy, so as to realize the power regulation of the gas water heater, and then improve the actual working voltage of the gas water heater, so as to ensure the working of the gas water heater, reduce the extinguishment of the gas water heater due to the abnormality of the power supply end of the gas water heater, affect the user experience, and avoid the increase of the production cost of the gas water heater.

[0064] The control method of the gas water heater provided by the embodiment determines a target power regulation strategy corresponding to the actual working voltage of the gas water heater when determining that the power supply end of the gas water heater is abnormal according to the actual working voltage of the gas water heater, so as to regulate the power of the gas water heater adaptively by using the target power regulation strategy, and thus the gas water heater can work in the case that the power supply end is abnormal, the problem of flameout of the gas water heater caused by the abnormal power supply end is reduced, the production cost of the gas water heater is reduced, and the user experience is improved.

[0065] Reference Figure 2 , Figure 2 The flowchart of another control method of a gas water heater is provided in the embodiment. The control method of the gas water heater provided by the embodiment comprises the following steps.

[0066] S201: After the gas water heater is ignited, the actual working voltage of the gas water heater is obtained.

[0067] In the embodiment, the step S201 is consistent with the step S101 described above, and the step S101 is described above, which will not be repeated here.

[0068] S202: The target comparison result between the actual working voltage and the rated working voltage corresponding to the gas water heater is determined.

[0069] S203: Whether the target comparison result is that the actual working voltage is less than the rated working voltage is determined.

[0070] S204: When the target comparison result is that the actual working voltage is less than the rated working voltage, it is determined that the power supply end of the gas water heater is abnormal.

[0071] For the steps S202-S204 described above, after the actual working voltage is obtained, the actual working voltage is compared with the rated working voltage corresponding to the gas water heater to obtain the target comparison result. When the target comparison result is that the actual working voltage is less than the rated working voltage, it is indicated that the power supply end of the gas water heater is abnormal. When the target comparison result is not that the actual working voltage is less than the rated working voltage, it is indicated that the power supply end of the gas water heater is normal, and at this time, the step S201 can be returned to continue to obtain the actual working voltage of the gas water heater.

[0072] S205: When the power supply end of the gas water heater is abnormal, the target power regulation condition corresponding to the actual working voltage is determined from the preset association relationship, and the preset association relationship stores a plurality of corresponding relationships between working voltages and preset power regulation conditions.

[0073] S206: Determine the target power regulation strategy of the gas water heater according to the target power regulation condition.

[0074] S207: Control the gas water heater according to the target power regulation strategy.

[0075] For the above S205 step-S207 step, when the power supply end of the gas water heater is abnormal, the abnormality degree of the power supply end of the gas water heater needs to be determined according to the actual working voltage of the gas water heater, so as to determine the target power regulation strategy of the gas water heater according to the abnormality degree of the power supply end of the gas water heater. The abnormality degree of the power supply end of the gas water heater is related to the preset power regulation condition, and after the target power regulation condition to which the actual working voltage belongs is determined according to the working voltage of the gas water heater, the abnormality degree of the current power supply end of the gas water heater can be determined. The abnormality degree of the power supply end of the gas water heater is used to indicate different power regulation strategies. When the abnormality degree of the power supply end of the gas water heater is low, it indicates that the working voltage of the gas water heater has changed slightly, and in this case, in order to keep the temperature and water flow of the gas water heater constant, the working current of the fan in the gas water heater is controlled; when the abnormality degree of the power supply end of the gas water heater is medium, it indicates that the input power of the gas water heater has changed greatly, and in this case, in order to keep the temperature of the gas water heater constant, the working current of the fan in the gas water heater and the working current of the water pump in the gas water heater are controlled; when the abnormality degree of the power supply end of the gas water heater is high, it indicates that the working voltage of the gas water heater is not enough to support the multifunctional work of the gas water heater, and at this time, only the normal output of hot water of the gas water heater needs to be ensured, in this case, the working current of the fan in the gas water heater, the working current of the water pump in the gas water heater and the working current of the proportional valve in the gas water heater are all controlled.

[0076] Wherein, when determining the abnormality of the power supply end of the gas water heater, the preset association relationship can be queried by using the actual working voltage of the gas water heater, so as to determine the target power regulation condition to which the actual working voltage belongs from the preset association relationship. The target power regulation condition includes a first power regulation condition, a second power regulation condition and a third power regulation condition, the abnormality degree of the power supply end of the gas water heater corresponding to the first power regulation condition is medium, the abnormality degree of the power supply end of the gas water heater corresponding to the second power regulation condition is low, and the abnormality degree of the power supply end of the gas water heater corresponding to the third power regulation condition is high.

[0077] The first power regulation condition comprises that the actual working voltage is less than a first preset working voltage and greater than or equal to a second preset working voltage. The first preset working voltage is a product between a first preset coefficient and the rated working voltage, and the second preset working voltage is a product between a second preset coefficient and the rated working voltage. The first preset coefficient is greater than the second preset coefficient, and both the first preset coefficient and the second preset coefficient are less than 1. In this embodiment, the first preset coefficient and the second preset coefficient are not limited, and can be set according to actual needs. In this embodiment, the actual working voltage is denoted as U 实 , the rated working voltage is denoted as U 额 , the first preset coefficient is 0.8, and the second preset coefficient is 0.6. Therefore, the first power regulation condition can be expressed as: 0.6U 额 ≤U 实 <0.8U 额 .

[0078] The second power regulation condition comprises that the actual working voltage is greater than or equal to the first preset working voltage and less than the rated working voltage. The first preset working voltage and the rated working voltage can be referred to the above description. The second power regulation condition can be expressed as: 0.8U 额 ≤U 实 <U 额 .

[0079] The third power regulation condition comprises that the actual working voltage is less than a second preset working voltage. The second preset working voltage can be referred to the above description. The third power regulation condition can be expressed as: U 实 <0.6U 额 .

[0080] In this embodiment, the target power regulation strategy corresponding to the gas water heater is determined according to the target power regulation condition in the step S206, comprising:

[0081] When the target power regulation condition is the first power regulation condition, the target power regulation strategy corresponding to the gas water heater is determined as the first power regulation strategy;

[0082] When the target power regulation condition is the second power regulation condition, the target power regulation strategy corresponding to the gas water heater is determined as the second power regulation strategy;

[0083] When the target power regulation condition is the third power regulation condition, the target power regulation strategy corresponding to the gas water heater is determined as the third power regulation strategy.

[0084] The first power regulation strategy is used to control the working current of the fan in the gas water heater and the working current of the water pump in the gas water heater. The second power regulation strategy is used to control the working current of the fan in the gas water heater. The third power regulation strategy is used to control the working current of the fan in the gas water heater, the working current of the water pump in the gas water heater, and the working current of the proportional valve in the gas water heater.

[0085] In this embodiment, the gas water heater is controlled according to the target power regulation strategy in S207, specifically including:

[0086] When the target power regulation strategy is the first power regulation strategy, the working current of the fan in the gas water heater is controlled to be reduced to reduce the power of the fan, and the working current of the water pump in the gas water heater is controlled to be reduced to reduce the power of the water pump.

[0087] When the target power regulation strategy is the second power regulation strategy, the working current of the fan in the gas water heater is controlled to be reduced to reduce the power of the fan.

[0088] When the target power regulation strategy is the third power regulation strategy, the working current of the fan in the gas water heater is controlled to be reduced to reduce the power of the fan, the working current of the water pump in the gas water heater is controlled to be reduced to reduce the power of the water pump, and the working current of the proportional valve in the gas water heater is controlled to be reduced to reduce the power of the proportional valve.

[0089] In the above, when the target power regulation strategy is the first power regulation strategy, the working currents of the fan and the water pump in the gas water heater are simultaneously controlled to be reduced, thereby realizing the reduction of the powers of the fan and the water pump, and on this basis, the actual working voltage of the entire gas water heater is improved, so that the gas water heater can maintain a constant temperature when the power supply end of the gas water heater is abnormal, reducing the situation that the gas water heater is extinguished due to the abnormality of its power supply end, and improving the user experience.

[0090] When the target power regulation strategy is the second power regulation strategy, only the working current of the fan in the gas water heater is controlled to be reduced, thereby realizing the reduction of the power of the fan, and on this basis, the actual working voltage of the entire gas water heater is improved, so that the gas water heater can maintain a constant temperature and a constant water flow when the power supply end of the gas water heater is abnormal, reducing the situation that the gas water heater is extinguished due to the abnormality of its power supply end, and improving the user experience.

[0091] When the target power regulation strategy is the third power regulation strategy, the working currents of the fan, the water pump and the proportional valve in the gas water heater are all reduced, so as to realize the reduction of the power of the fan, the reduction of the power of the water pump and the reduction of the power of the proportional valve, and then the gas water heater can obtain the working voltage, so as to ensure that the gas water heater can still keep minimum load operation and normally output hot water in the case that the input power of the power supply end of the gas water heater is seriously insufficient, thereby reducing the situation that the gas water heater is extinguished due to the abnormality of the power supply end, and improving the user experience.

[0092] In order to ensure the control reliability of the gas water heater, during the process of controlling the reduction of the working current of the fan, the working current of the water pump and the working current of the proportional valve, it is determined whether the working current of the fan reaches the first preset current corresponding to the fan, whether the working current of the water pump reaches the second preset current corresponding to the water pump and whether the working current of the proportional valve reaches the third preset current corresponding to the proportional valve.

[0093] When the working current of the fan reaches the first preset current, the control stops reducing the working current of the fan.

[0094] When the working current of the water pump reaches the second preset current, the control stops reducing the working current of the water pump.

[0095] When the working current of the proportional valve reaches the third preset current, the control stops reducing the working current of the proportional valve.

[0096] In the embodiment, the specific values of the first preset current, the second preset current and the third preset current can be set according to actual needs, and the specific values of the first preset current, the second preset current and the third preset current are not limited in the embodiment. In order to avoid affecting the working reliability of the gas water heater due to the over-limit control of the working currents of the fan, the water pump and the proportional valve, the first preset current is greater than the minimum working current allowed by the fan and is a value near the minimum working current allowed by the fan, the second preset current is greater than the minimum working current allowed by the water pump and is a value near the minimum working current allowed by the water pump, and the third preset current is greater than the minimum working current allowed by the proportional valve and is a value near the minimum working current allowed by the proportional valve. The processor obtains the working current of the fan through the voltage-current detection module in the fan to control the stop of the reduction of the working current of the fan. The processor obtains the working current of the water pump through the voltage-current detection module in the water pump to control the stop of the reduction of the working current of the water pump. The processor obtains the working current of the proportional valve through the voltage-current detection module in the proportional valve to control the stop of the reduction of the working current of the proportional valve.

[0097] It should be noted that, in the process of controlling the gas water heater according to the second power regulation strategy, it is determined whether the working current of the fan reaches the first preset current corresponding to the fan, and when the working current of the fan reaches the first preset current, the control stops reducing the working current of the fan. In the process of controlling the gas water heater according to the first power regulation strategy, it is determined whether the working current of the fan reaches the first preset current corresponding to the fan and whether the working current of the pump reaches the second preset current corresponding to the pump, and when the working current of the fan reaches the first preset current, the control stops reducing the working current of the fan, and when the working current of the pump reaches the second preset current, the control stops reducing the working current of the pump. The first preset current and the second preset current can be referred to the above description. In the above manner, the working reliability of the gas water heater in the control process of the gas water heater is ensured.

[0098] In this embodiment, after the step of controlling the gas water heater according to the target power regulation strategy is performed, the control method for the gas water heater provided by the embodiment further includes the following steps:

[0099] determining whether the gas water heater is extinguished;

[0100] when the gas water heater is extinguished, determining the fault prompt information corresponding to the gas water heater;

[0101] displaying the fault prompt information on the display module in the gas water heater; or

[0102] pushing the fault prompt information to a target terminal corresponding to the gas water heater, so that the target terminal displays the fault prompt information.

[0103] After the power regulation control of the gas water heater is performed, if the gas water heater is still extinguished, it indicates that the gas water heater may have a fault at this time, and manual intervention is required to enable the gas water heater to work normally. When the gas water heater is extinguished, one way is to display the corresponding fault prompt information through the display module in the gas water heater, and the specific form of the fault prompt information can be set according to actual needs, which is not limited in the embodiment. Another way is that the processor in the gas water heater pushes the fault prompt information to a target terminal corresponding to the gas water heater through the wireless communication module provided in the gas water heater, so that the target terminal displays the fault prompt information. Through the above two ways, the user of the gas water heater can know that the gas water heater has a fault at present, and needs to be repaired immediately to ensure the normal use of the gas water heater. The target terminal can be a mobile phone, a tablet computer, etc. The specific form of the target terminal can be selected according to actual needs, which is not specifically limited in the embodiment. It should be noted that a voice module can also be provided in the gas water heater, and the voice module plays the fault prompt information when the gas water heater is extinguished.

[0104] S208: If the target comparison result is not that the actual working voltage is less than the rated working voltage, return to perform S201.

[0105] In this embodiment, when the target comparison result is not that the actual working voltage is less than the rated working voltage, the power supply end of the gas water heater is normal, at this time, the step S201 can be returned to continue to obtain the actual working voltage of the gas water heater.

[0106] Reference Figure 3 , the following will be specifically introduced as an example, a whole gas water heater control process, as follows:

[0107] When the gas water heater is ignited, if the power supply end of the gas water heater appears abnormal to cause the output power to change, the current and voltage will change accordingly, and the current and voltage detection module of each electrical component of the gas water heater detects that the voltage and current change, at this time, the processor obtains the actual working voltage of the current gas water heater, which is marked as U 实 , the processor compares U 实 with the rated working voltage U 额 of the gas water heater, if U 实 <U 额 , three power regulation conditions will be obtained, the first power regulation condition is 0.6U 额 ≤U 实 <0.8U 额 , the second power regulation condition is 0.8U 额 ≤U 实 <U 额 , and the third power regulation condition is U 实 <0.6U 额 , the judgment factors of the above power regulation conditions are mainly the size relationship between U 实 and U 额 , because U 实 drops to different degrees, the power regulation strategies taken are also different, and the working states of the gas water heater are also different, so first of all, the size relationship between U 实 and U 额 must be judged.

[0108] Case one: if the gas water heater meets the power regulation condition 0.8U 额 ≤U 实 <U 额When the input voltage has a small change, the gas water heater still needs to maintain constant temperature and water flow, the processor will reduce the power of the fan by 20% and reduce the speed of the fan, the power of the water pump and the proportional valve is not changed, the current of the fan is relatively reduced to reduce the power of the fan, so that the actual working voltage of the gas water heater rises, so that the gas water heater can still maintain small load operation under the condition of power reduction of the power supply end, and still can normally output hot water to ensure water flow and reduce the situation of accidental shutdown of the gas water heater. If the gas water heater still accidentally shuts down, the processor sends shutdown information to the target terminal through the wireless communication module, or the display module in the gas water heater displays power shortage fault.

[0109] Case two: if the gas water heater meets the power regulation condition 0.6U 额 ≤U 实 <0.8U 额 , the input voltage has a large change, and the gas water heater still needs to maintain constant temperature, the processor will reduce the power of the fan and the water pump by 20% and reduce the speed of the fan, the power of the proportional valve is not changed, the current of the fan and the water pump is reduced by the processor, so that the power of the fan and the water pump is reduced, so that the actual working voltage of the gas water heater rises, so that the gas water heater can still maintain small load operation under the condition of power shortage of the power supply end, and still can normally output hot water to reduce the situation of accidental shutdown of the gas water heater. If the gas water heater still accidentally shuts down, the processor sends shutdown information to the target terminal through the wireless communication module, or the display module in the gas water heater displays power shortage fault.

[0110] Case three: if the gas water heater meets the power regulation condition U 实 <0.6U 额 , the input voltage is not enough to support the multifunctional work of the gas water heater, the processor will reduce the power of the fan, the water pump and the proportional valve by 20% and reduce the speed of the fan, the current of the fan, the water pump and the proportional valve is reduced by the processor, so that the gas water heater obtains the working voltage, so that the gas water heater can still maintain minimum load operation under the condition of serious power shortage of the power supply end, and still can normally output hot water to reduce the situation of accidental shutdown of the gas water heater. If the gas water heater still accidentally shuts down, the processor sends shutdown information to the target terminal through the wireless communication module, or the display module in the gas water heater displays power shortage fault.

[0111] The control method of the gas water heater provided in the embodiment determines a target power regulation strategy corresponding to the gas water heater according to an actual working voltage of the gas water heater when determining that a power supply end of the gas water heater is abnormal, so as to regulate the power of the gas water heater adaptively by using the target power regulation strategy, and thus the gas water heater can work in the case that the power supply end is abnormal, the problem of flameout of the gas water heater caused by the abnormal power supply end is reduced, the production cost of the gas water heater is reduced, and the use experience of the user is improved.
