[0002] At present, gas water heaters based on full premix combustion technology premix gas (such as natural gas) and air into a uniform premixed gas, and burn the premixed gas in the burner to release heat and heat the water. Since the gas and oxygen are fully mixed, the combustion efficiency can be improved and the emission of harmful substances can be reduced.

[0003] Then, the gas and air (oxygen) in the premixed gas need to be in a certain ratio to achieve the best combustion state, otherwise it will cause incomplete combustion.

[0045] The application scenarios of the embodiments of the present invention are explained below:

[0046] Figure 1 This is an application scenario diagram of the gas water heater initialization method provided in the embodiment of the present invention. The gas water heater initialization method provided in the embodiment of the present invention can be applied to the scenario of initializing an intelligent hot gas water heater. For example, Figure 1 As shown, the method provided by the embodiment of the present invention can be applied to a smart gas water heater. When the smart gas water heater is operated for the first time, it can enter the initialization state by default or according to the user operation. After that, the smart gas water heater executes the gas water heater initialization method provided by the embodiment of the present invention to adjust the air intake of the combustion unit at each combustion power so that the combustion unit of the gas water heater maintains a high combustion efficiency during operation. Among them, during the initialization process, the smart gas water heater can obtain the required initialization configuration by communicating with the cloud service. The initialization configuration includes, for example, the air pressure information and gas thermal value information of the area where the smart gas water heater is located. And the initialization data generated after the initialization process is completed is sent to the server. And, when the gas water heater is not in the first operation state, it receives the initialization instruction sent by the terminal device, enters the initialization state, and runs the gas water heater initialization method provided by this embodiment.

[0047] In the prior art, the gas water heater based on the full premix combustion technology sets the default air intake and gas intake at the factory, and performs gas premixing based on the air-fuel ratio corresponding to the ratio of the two. However, in the actual use process of the user, it is affected by various factors, such as the local air pressure, or the content of effective combustion components in the gas introduced into the gas water heater, so that the intake volume set by the default value when the gas water heater leaves the factory for other premixed gases often cannot reach the optimal air-fuel ratio. Adjusting the intake volume during the operation of the gas water heater will cause temperature fluctuations, which will not only affect the combustion efficiency, but also affect the user's water use experience. Therefore, there is an urgent need for a method that can initialize the combustion unit of the gas water heater during the initialization stage of the gas water heater, that is, to avoid water temperature fluctuations caused by real-time adjustments made by users during water use, and to improve combustion efficiency and reduce the emission of harmful substances.

[0048] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0049] Figure 2 A flow chart of a method for initializing a gas water heater provided in one embodiment of the present invention is applied to a gas water heater, wherein the gas water heater includes a combustion unit, such as Figure 2 As shown, the gas water heater initialization method provided in this embodiment includes the following steps:

[0050] Step S101, controlling the combustion unit to operate at a target combustion power, and obtaining detection current information, where the detection current information is used to characterize the current value formed by flame ions during the combustion process of the flame in the combustion unit.

[0051] Exemplarily, after the gas water heater enters the initialization mode, the target combustion power is determined in sequence according to the configuration information corresponding to the initialization mode, and the operation of the combustion unit of the gas water heater is controlled based on the target combustion power, wherein the target combustion power may correspond to the combustion gear of the combustion unit, or the set temperature of the gas water heater, and the greater the combustion power, the greater the air intake of the combustion unit.

[0052] Further, exemplarily, a detection circuit for flame detection is provided in the combustion unit. Specifically, the detection circuit includes a signal acquisition module for detecting flames, a sampling modulation module, a shaping module, and a signal source. After the combustion unit is running, the flame particles are detected by the signal acquisition module, and adjustment, shaping, and other steps are performed to output a detection current. Then, the controller of the gas water heater generates detection current information according to the current value of the detection current. The magnitude of the current value corresponds to the number of flame particles. According to the detection current information, the amount of flame particles generated by the flame combustion in the combustion unit when the combustion unit is running at the target combustion power can be determined.

[0053] Among them, the specific implementation steps of current detection of the flame in the combustion unit, as well as the design and implementation of the detection circuit, are existing technologies known to those skilled in the art and will not be described in detail here.

[0054] Step S102, determining the air-fuel ratio according to the detected current information, where the air-fuel ratio represents the mixing ratio of air and fuel gas in the combustion unit.

[0055] Exemplarily, the air-fuel ratio is an indicator that characterizes the mixing ratio of air and gas (such as natural gas) in a combustion unit. When the air and gas are premixed in the combustion unit, the combustion efficiency is optimal when the mixing ratio of air and gas is a specific target value (such as 3 to 1) or is in a target range. When it is less than or greater than the target value or target range, the combustion efficiency decreases. Among them, the detected current information includes a current waveform, which is, for example, a square wave. Different air-fuel ratios can be characterized according to the current values ​​corresponding to the low level and high level of the square wave. In the process of air-fuel ratio change, different air-fuel ratios correspond to unique high-level current values ​​and low-level current values ​​of the square wave. Therefore, by detecting the current information, a unique air-fuel ratio can be determined. Figure 3 A schematic diagram of the corresponding relationship between the detection current information and the air-fuel ratio provided in an embodiment of the present disclosure, such as Figure 3As shown in the figure, when the detection current information is square wave A, the high level of square wave A corresponds to current a, and the low level corresponds to current b. At this time, the square wave A corresponds to an air-fuel ratio of 2; as the intake volume in the combustion unit changes, the air-fuel ratio changes, and the detection current information also changes accordingly. As shown in the figure, when the detection current information is square wave B, the high level of square wave B corresponds to current c, and the low level corresponds to current d. At this time, the square wave B corresponds to an air-fuel ratio of 3. It can be seen from the above that when the air-fuel ratio changes, the detection current information changes accordingly. According to the current waveform represented by the detection current information, the air-fuel ratio in the current gas unit can be determined.

[0056] In one possible implementation, the air-fuel ratio is determined based on the detected current information, including: obtaining a preset current mapping relationship, the current mapping relationship is used to characterize the mapping relationship between the current value formed by flame ions and the air-fuel ratio under different combustion powers; based on the current mapping relationship and the target combustion power of the gas water heater, determining the air-fuel ratio corresponding to the detected current information.

[0057] Among them, the current mapping relationship is data preset in the local gas water heater or cloud server. Through the current mapping relationship and the target combustion power of the gas water heater, the air-fuel ratio of the gas water heater under the current target combustion power is determined.

[0058] Step S103, adjusting the intake air amount of the combustion unit according to the air-fuel ratio until the air-fuel ratio reaches a preset target value.

[0059] Exemplarily, the intake volume includes the air intake volume and the gas intake volume. The preset target value of the air-fuel ratio refers to the optimal air-fuel ratio, or the optimal air-fuel ratio range. According to the difference between the air-fuel ratio and the preset target value, the air intake volume and / or the gas intake volume are adjusted to adjust the current air-fuel ratio of the combustion unit to the optimal air-fuel ratio or enter the optimal air-fuel ratio range, so that the combustion efficiency of the combustion unit is maximized at the current target combustion power. More specifically, for example, when the air-fuel ratio is higher than the target value, the air intake volume can be reduced, and / or the gas intake volume can be increased; conversely, when the air-fuel ratio is lower than the target value, the air intake volume can be increased, and / or the gas intake volume can be reduced.

[0060] In this embodiment, the combustion unit is controlled to operate at the target combustion power and the detection current information is obtained. The detection current information is used to characterize the current value formed by the flame ions during the combustion process of the flame in the combustion unit; the air-fuel ratio is determined based on the detection current information, and the air-fuel ratio characterizes the mixing ratio of air and gas in the combustion unit; the air intake of the combustion unit is adjusted according to the air-fuel ratio until the air-fuel ratio reaches the preset target value. By detecting the air-fuel ratio in the initialization stage of the gas water heater and adjusting the air intake based on the air-fuel ratio, the initialization optimization of the combustion unit in the gas water heater is achieved, avoiding the problem of insufficient combustion of gas in the combustion unit due to various reasons, improving combustion efficiency, and reducing harmful substance emissions.

[0061] Figure 4 A flow chart of a method for initializing a gas water heater provided by another embodiment of the present invention is as follows: Figure 4 As shown, the gas water heater initialization method provided in this embodiment is Figure 2 Based on the gas water heater initialization method provided in the illustrated embodiment, step S103 is further refined, and a step of uploading the initialization data to the server for regional synchronization is added.

[0062] The gas water heater initialization method provided in this embodiment includes the following steps:

[0063] Step S201, controlling the combustion unit to operate at different target combustion powers in sequence, and obtaining corresponding detection current information, where the detection current information is used to characterize the current value formed by flame ions during the combustion process of the flame in the combustion unit.

[0064] Step S202, determining the air-fuel ratio corresponding to the target combustion power according to the detected current information, where the air-fuel ratio represents the mixing ratio of air and fuel gas in the combustion unit.

[0065] Step S203, determining a combustion state value according to the air-fuel ratio, where the combustion state value is used to characterize the heat released by the flame in the combustion unit.

[0066] Exemplarily, different air-fuel ratios correspond to combustion state values, and the combustion state values ​​are used to characterize the heat released by the flame in the combustion unit. In a possible implementation, the air intake of the combustion unit is adjusted according to the air-fuel ratio, including: determining the combustion state value according to the air-fuel ratio, and when the heat corresponding to the combustion state value is less than a preset reference heat, adjusting the air intake and / or gas intake of the combustion unit.

[0067] In a possible implementation, the implementation of adjusting the air intake amount and / or the gas intake amount of the combustion unit includes:

[0068] When the heat corresponding to the combustion state value is less than the preset reference heat, the air intake volume is kept constant, and the gas intake volume is adjusted at the same time. More specifically, for example, the gas valve opening is adjusted by the controller to adjust the gas intake volume, so as to adjust the air-fuel ratio so that the air-fuel ratio is in a preset range (for example, the air-fuel ratio is in the range of 1.2-1.4). When the air-fuel ratio of the mixed gas is in the preset range, the heat release efficiency during combustion is higher. In the steps of this embodiment, due to the influence of the air pressure conditions in various regions, the oxygen content in the air is different. Therefore, compared with adjusting the intake volume, the method of adjusting the gas intake volume to change the air-fuel ratio has better stability and accuracy, so that the air-fuel ratio of the mixed gas can reach a more ideal state and improve the combustion efficiency.

[0069] Step S204: when the heat corresponding to the combustion state value is less than a preset reference heat, the air intake and / or gas intake of the combustion unit is adjusted based on the position information of the gas water heater.

[0070] Exemplarily, after the air-fuel ratio is determined, when the heat corresponding to the combustion state value corresponding to the air-fuel ratio is less than the preset reference heat, it means that the current air-fuel ratio is not ideal and the combustion unit has a problem of low combustion efficiency. Here, it is necessary to adjust the air intake and / or gas intake of the combustion unit. Specifically, when the gas water heater leaves the factory, the parameters of the air intake and gas intake have been adjusted according to the type of gas it is adapted to. In theory, even if it is used directly, the air intake and gas intake in the combustion unit can achieve the optimal air-fuel ratio. However, in actual use, it will be affected by the regional location. For example, in high-altitude areas, due to the thin air, the oxygen content entering the combustion unit decreases. Therefore, there is a certain difference between the actual air-fuel ratio and the theoretically designed air-fuel ratio. As a result, the combustion efficiency of the flame of the combustion unit is reduced, and this difference is caused by the location and region of the gas water heater. Therefore, by obtaining the location information of the gas water heater, determining the information representing the thermal value of the gas and the information representing the gas pressure value corresponding to the location of the gas water heater based on the location information, and then adjusting the gas water heater accordingly, the combustion efficiency of the flame of the combustion unit in the gas water heater can be improved.

[0071] Furthermore, when it is determined that the air-fuel ratio is too low or too high, since the air-fuel ratio is adjusted by two parameters, the air intake amount and the gas intake amount, the air-fuel ratio can be adjusted from two aspects, so that the air-fuel ratio reaches the target value. How to adjust the air intake amount and the gas intake amount to further improve the combustion efficiency and improve the user experience is the problem to be solved in the steps of this embodiment.

[0072] In one possible implementation, Figure 5As shown, step S204 includes two specific implementation steps, step S2041 and step S2042:

[0073] Step S2041, obtaining a preset reference air pressure value, where the reference air pressure value represents the air pressure value of the area where the gas water heater is located.

[0074] Step S2042: adjusting the air intake and / or gas intake of the combustion unit according to the reference air pressure value.

[0075] Exemplarily, when the air-fuel ratio is less than a first preset value, if the reference air pressure value is less than the standard air pressure value, the air intake of the combustion unit is increased; if the reference air pressure value is greater than or equal to the standard air pressure value, the gas intake of the combustion unit is reduced; when the air-fuel ratio is greater than a second preset value, if the reference air pressure value is less than the standard air pressure value, the gas intake of the combustion unit is increased; if the reference air pressure value is greater than or equal to the standard air pressure value, the air intake of the combustion unit is reduced, wherein the first preset value is less than the second preset value.

[0076] Specifically, the first preset value and the second preset value are the lower limit and the upper limit of the optimal air-fuel ratio range, respectively. When the air-fuel ratio is lower than the first preset value or higher than the second preset value, the air intake amount and / or the fuel gas intake amount need to be adjusted.

[0077] In one possible implementation, when the air-fuel ratio is less than a first preset value, if the reference air pressure value is less than the standard air pressure value, that is, the gas water heater is in a low-pressure area, then by increasing the air intake of the combustion unit, the oxygen content in the combustion unit can be increased, thereby improving the combustion efficiency; if the reference air pressure value is greater than or equal to the standard air pressure value, that is, the gas water heater is in a normal air pressure area, in this case, it is determined that the low air-fuel ratio is caused by inaccurate (too large) gas intake, and therefore the gas intake of the combustion unit is reduced, thereby improving the combustion efficiency and reducing the waste of gas.

[0078] In another possible implementation, when the air-fuel ratio is greater than the second preset value, if the reference air pressure value is less than the standard air pressure value, that is, the gas water heater is in a low-pressure area, and the problem of excessively high air-fuel ratio occurs in the low-pressure area, which is usually caused by too low gas intake, the gas intake of the combustion unit is increased; if the reference air pressure value is greater than or equal to the standard air pressure value, that is, the gas water heater is in a normal air pressure area, the air intake of the combustion unit is reduced to reduce the air-fuel ratio, improve combustion efficiency, and ensure that the total combustion power is increased.

[0079] Optionally, when the air-fuel ratio is less than the first preset value, if the reference air pressure value is less than the standard air pressure value, the method further includes: reducing the gas intake of the combustion unit. Exemplarily, when the air-fuel ratio is too low and the reference air pressure value is less than the standard air pressure value, that is, when the gas water heater is located in a low-pressure area, in some low-pressure areas, the ability to increase the oxygen content in the combustion unit by increasing the air intake is limited, and even if the air intake is increased to the maximum, it may not be able to meet the target air-fuel ratio requirement. At this time, reducing the gas intake of the combustion unit at the same time can make the air-fuel ratio in the combustion unit reach the target air-fuel ratio, thereby avoiding gas waste caused by too low an air-fuel ratio.

[0080] In another possible implementation, Figure 6 As shown, step S204 includes two specific implementation steps, step S2043 and step S2044.

[0081] Step S2043, obtaining a preset reference thermal value, where the reference thermal value represents the thermal value of the gas connected to the combustion unit.

[0082] Step S2044, adjusting the air intake and / or gas intake of the combustion unit according to the reference thermal value.

[0083] For example, the calorific value of the gas refers to the calorific value released after the gas is mixed and fully burned. The calorific value of the gas is determined by the content and concentration of the combustible substances in the gas. Due to reasons such as processing technology, the calorific value of the gas in different regions may be different. In this embodiment, the air-fuel ratio is adjusted based on the calorific value of the gas so that the air-fuel ratio reaches the target value, thereby improving the combustion efficiency and reducing energy waste.

[0084] Exemplarily, when the air-fuel ratio is less than a first preset value, if the reference thermal value is less than the standard thermal value, the air intake of the combustion unit is increased; if the reference thermal value is greater than or equal to the standard thermal value, the gas intake of the combustion unit is reduced; when the air-fuel ratio is greater than a second preset value, if the reference thermal value is less than the standard thermal value, the gas intake of the combustion unit is increased; if the reference thermal value is greater than or equal to the standard thermal value, the air intake of the combustion unit is reduced, wherein the first preset value is less than the second preset value.

[0085] In one possible implementation, when the air-fuel ratio is less than a first preset value, if the reference thermal value is less than the standard thermal value, that is, the thermal value of the gas in the area where the gas water heater is located is low, in order to avoid further decrease in combustion power caused by reducing the gas intake volume, affecting the output water temperature of the gas water heater, the air intake volume of the combustion unit is increased to increase the air-fuel ratio and improve the combustion efficiency; if the reference thermal value is greater than or equal to the standard thermal value, that is, the thermal value of the gas in the area where the gas water heater is located is normal or high, then reducing the gas intake volume of the combustion unit can reduce gas consumption and reduce gas costs. At the same time, due to the improved combustion efficiency, the output water temperature of the gas water heater will not be reduced.

[0086] In another possible implementation, when the air-fuel ratio is greater than the second preset value, if the reference thermal value is less than the standard thermal value, that is, the thermal value of the gas in the area where the gas water heater is located is low, the gas intake of the combustion unit is increased, and the air intake is reduced. Even if the target air-fuel ratio can be achieved, the total combustion power may still be insufficient due to the low thermal value. Therefore, by increasing the gas intake of the combustion unit, the air-fuel ratio is reduced, and the combustion power of the combustion unit is increased, the heating demand of the gas water heater is met;

[0087] If the reference thermal value is greater than or equal to the standard thermal value, that is, the thermal value of the gas in the area where the gas water heater is located is normal or high, then the air intake of the combustion unit is reduced. In this case, since the thermal value of the gas in the area where the gas water heater is located is normal or high, the air intake can be reduced, the air-fuel ratio can be reduced, and the combustion efficiency can be improved. The water output of the gas water heater can meet the requirements without increasing the gas intake, which can save gas consumption and reduce the cost of gas use.

[0088] Step S205, after the air-fuel ratio reaches a preset target value, the air intake amount and the fuel gas intake amount of the combustion unit are saved as reference intake amounts.

[0089] Step S206, obtaining the location information of the gas water heater, generating initialization data according to the reference air intake volume and the location information, and sending the initialization data to the server, wherein the initialization data is used to initialize other gas water heaters in the same area as the gas water heater.

[0090] Exemplarily, after the air-fuel ratio reaches the target value under the target combustion power through the above steps, the corresponding air intake volume and gas intake volume are saved. After the initialization state ends, during the normal operation of the gas water heater, when the gas water heater operates at the target combustion power, the gas is mixed with the air intake volume and gas intake volume adjusted by the initialization, so that the air-fuel ratio reaches the optimal state. At the same time, since the adjustment process of the air-fuel ratio is combined with the location information of the gas water heater, initialization data is generated based on the reference intake volume and location information, and uploaded to the cloud server. When other gas water heaters in the same area as the gas water heater are running, there is no need to initialize again, and the initialization data generated in this embodiment is used to adjust the intake volume, thereby improving the combustion efficiency.

[0091] In this embodiment, the implementation method of step S201-step S202 is the same as that of the present invention. Figure 2 The implementation methods of step S101 and step S102 in the illustrated embodiment are the same and will not be described in detail here.
