[0088] The present disclosure is further described below by way of examples, but the present disclosure is not limited to the scope of the examples.

[0089] Prefixes such as "first" and "second" are used in the embodiments of the present disclosure only to distinguish different description objects, and have no limiting effect on the position, order, priority, quantity or content of the described objects. The use of prefixes such as ordinal numbers to distinguish description objects in the embodiments of the present disclosure does not constitute a limitation on the described objects. For the statement of the described objects, please refer to the description in the context of the claims or embodiments, and no unnecessary limitation should be constituted due to the use of such prefixes.

[0090] Example 1

[0091] Before the water heater is started and ignited, it needs to use a fan for pre-cleaning, and the wind speed for the pre-cleaning is high and the time is short. After the pre-cleaning is completed, it will immediately enter the ignition state. Since the ignition time of the water heater is too short, the fan state is unstable, and it is difficult to judge whether there is wind pressure in the outside world, which leads to the risk of flameout when starting the water heater.

[0092] In view of this, the present embodiment provides a method for controlling wind pressure resistance of a water heater to improve the wind pressure resistance capability of the water heater.

[0093] like Figure 1 As shown, the wind pressure control method includes:

[0094] S11: When the fan is started for cleaning before the water heater is ignited, a plurality of first parameter information within a preset time period is obtained.

[0095] The first parameter information is characterized as parameter information when the water heater fan is running.

[0096] S12: Determine whether there is external wind pressure on the water heater based on the first parameter information.

[0097] If so, target parameter information for resisting the external wind pressure is obtained based on the external wind pressure, and the operating parameters of the fan are adjusted based on the target parameter information to resist the external wind pressure of the water heater.

[0098] If not, the operating parameters of the fan are directly adjusted to preset parameter information, wherein the preset parameter information is characterized as parameter information of the fan when there is no external wind pressure.

[0099] In this embodiment, when the fan is started for cleaning before the water heater is ignited, the water heater is cleaned using the fan's lowest wind speed. Since the fan runs at the lowest wind speed, it will not disturb the user, further improving the user experience.

[0100] The water heater needs to be cleaned by a fan before ignition. However, the wind speed is relatively high at the moment of startup and the time is short, so it will ignite immediately. This solution uses ultra-low speed and long time to clean the water heater, which is equivalent to the cleaning effect of high speed and short time.

[0101] By adopting low-speed cleaning, extending the cleaning time, and adding wind pressure resistance judgment logic during the post-cleaning time, it is judged whether there is external wind pressure. Since the wind speed used in the post-cleaning is relatively low and the duration is relatively long, it is easy to make a correct judgment, and in the subsequent ignition, consider whether to increase the wind speed to improve the wind pressure resistance, so that the water heater can adapt to the changes in external wind pressure and maintain stable combustion and efficient operation of the water heater when external wind pressure exists.

[0102] When the water heater is ignited and the fan is started for cleaning, it is determined whether there is external wind pressure outside the water heater by obtaining parameter information of the fan when the water heater is running within a preset time period. When there is external wind pressure, the operating parameters of the fan are adjusted based on the external wind pressure information, so that the water heater can adapt to changes in external wind pressure and maintain stable combustion and efficient operation of the water heater when external wind pressure exists.

[0103] In this embodiment, the first parameter information is the current speed information and current current information of the fan.

[0104] like Figure 2 As shown, in one embodiment, the step of determining whether the water heater has external wind pressure based on the first parameter information specifically includes:

[0105] S21: Collecting current speed information and current current information corresponding to a number of moments within a preset time period.

[0106] S22: Obtain a standard speed table of the fan; the standard speed table includes standard speed information corresponding to different currents of the fan when there is no external wind pressure.

[0107] S23: Based on the standard speed table, a plurality of first difference information is obtained, where the first difference information is characterized by the difference between the standard speed information and the current speed information under the current current information.

[0108] S24: Determine whether the first difference information exceeds a first preset threshold.

[0109] If yes, counting a first amount of first difference information exceeding a first preset threshold;

[0110] If not, the next time period is used as the preset time period, and the process returns to step S21.

[0111] S25: Determine whether the first quantity exceeds a second preset threshold.

[0112] If yes, the next time period is used as the preset time period, and the process returns to step S21.

[0113] If not, there is external wind pressure on the water heater.

[0114] In a specific implementation, 100 pieces of current speed information and current current information are collected within a preset time period, and the 100 pieces of current speed information are respectively subtracted from the standard speed information corresponding to the current current information to form 100 first difference information, wherein it is respectively determined whether the first difference information exceeds a first preset threshold, and the first number of first difference information exceeding the first preset threshold is counted. If the first number exceeds a second preset threshold, such as 80, it indicates that there is external wind pressure outside the water heater, and the fan parameters need to be adjusted to counteract the external wind pressure.

[0115] like Figure 3 As shown, in one embodiment, the step of determining whether the water heater has external wind pressure based on the first parameter information specifically includes:

[0116] S31: Collect the current speed information and the corresponding current current information at the current moment.

[0117] S32: Obtain a standard speed table of the fan; the standard speed table includes standard speed information corresponding to different currents of the fan when there is no external wind pressure.

[0118] S33: Based on the standard speed table, first difference information is obtained, where the first difference information is represented by the difference between the standard speed information and the current speed information under the current current information.

[0119] S34: Determine whether the first difference information exceeds a first preset threshold.

[0120] If yes, start counting the first duration of time that the first difference information exceeds the first preset threshold, and perform again at the next moment to determine whether the first difference information exceeds the first preset threshold;

[0121] If not, the next moment is taken as the current moment, and the process returns to step S31.

[0122] S35: Determine whether the first duration exceeds a first preset duration.

[0123] If so, there is external wind pressure on the water heater;

[0124] If not, the next moment is taken as the current moment, and the process returns to step S31.

[0125] In a specific implementation, the current speed information and the current current information corresponding to the current moment are collected, and the standard speed information corresponding to the current current information is obtained at the same time. A difference is made based on the current speed information and the standard speed information to form a first difference. It is determined whether the first difference exceeds a first preset threshold value. If so, the first duration of the first difference information exceeding the first preset threshold value is counted. When the first duration exceeds the first preset duration, it indicates that there is external wind pressure outside the water heater, and the fan parameters need to be adjusted to counteract the external wind pressure.

[0126] By comparing the current speed information corresponding to the current current information within a preset time period with the standard speed information, the external wind pressure of the water heater can be accurately obtained, and then according to the specific external wind pressure conditions, the operating parameters of the fan can be adjusted to cope with the external wind pressure, thereby improving the operating efficiency of the water heater.

[0127] In this embodiment, the step of obtaining target parameter information for resisting external wind pressure based on external wind pressure information specifically includes:

[0128] Based on the first difference information, obtaining a difference current corresponding to the fan that needs to be compensated;

[0129] The differential current is added to the current parameter information to serve as the target parameter information.

[0130] In a specific implementation, any fan corresponds to a fan speed when driven by an electric current. When there is external wind pressure, the current of the fan is increased, thereby increasing the input power of the fan and increasing the fan speed, so that the water heater can adapt to changes in external wind pressure and maintain stable combustion and efficient operation of the water heater when external wind pressure exists.

[0131] By making corresponding compensation for the current current information corresponding to the current speed information, the water heater can adapt to changes in external wind pressure and maintain stable combustion and efficient operation of the water heater when external wind pressure exists.

[0132] like Figure 4 As shown, the first parameter information in this embodiment is the external wind pressure information of the fan; the step of judging whether there is external wind pressure of the water heater based on the first parameter information specifically includes:

[0133] S41: Collecting external wind pressure information of the fan during operation through a wind pressure sensor.

[0134] S42: Directly determine whether the water heater has external wind pressure based on the external wind pressure information.

[0135] By directly collecting external wind pressure information, the external wind pressure information when the fan is running can be directly obtained, and the external wind pressure can be quickly adjusted according to the obtained external wind pressure information, so as to ensure stable combustion and efficient operation of the water heater when external wind pressure exists.

[0136] like Figure 5 As shown, in this embodiment, before obtaining the first parameter information, the control method further includes:

[0137] S51: Acquire water flow information in the water heater.

[0138] S52: Determine whether the water flow information is greater than a second preset threshold.

[0139] If yes, obtain the first parameter information;

[0140] If not, the fan is started at the minimum speed and the second duration of water flow information is started;

[0141] S53: Determine whether the second duration exceeds a second preset duration.

[0142] If the second preset time period is exceeded, obtaining the first parameter information;

[0143] If the second preset time period is not exceeded, the operating parameters of the fan are adjusted to the preset parameter information.

[0144] In one embodiment, a timer is set in the water heater to determine whether the duration exceeds a preset time. For example, a preset time is set for the timer. When water flow information exists and the corresponding water flow information is less than a first threshold, the timer starts a countdown. When the countdown ends, if the corresponding water flow information still exists, the anti-wind pressure mode is entered, that is, the step of obtaining the first parameter information is entered. At the same time, the timer is restored to the preset time and waits for the next water flow signal.

[0145] By comparing whether the duration of the water flow information in the water heater exceeds the preset time, the water flow conditions in the water heater can be accurately obtained, and whether to turn on the water heater is determined based on the specific water flow conditions, thereby avoiding frequent startup of the water heater due to water flow fluctuations and reducing energy loss.

[0146] Furthermore, by using the minimum parameter information of the fan to pre-clean the water heater, the user experience is improved while ensuring the stability, efficiency and safety of the water heater.

[0147] Before obtaining the water flow information in the water heater, the control method of this embodiment further includes:

[0148] Determine whether there is a water flow signal in the water heater, and if so, obtain water flow information in the water heater based on the water flow signal;

[0149] If not, the water heater is controlled to enter standby mode.

[0150] In this embodiment, water flow signals are collected by a water flow sensor, and the water flow rate in the water heater per unit time can be determined by the water flow signal, so that the water flow condition in the water heater can be accurately obtained according to the obtained water flow rate, and whether to turn on the water heater can be determined according to the specific water flow condition, thereby avoiding frequent startup of the water heater due to water flow fluctuations and reducing energy loss.

[0151] The following is a detailed description of the implementation principle of the wind pressure resistance control method of the water heater in this embodiment with reference to an example:

[0152] like Figure 6 As shown, the water heater enters the standby state after power-on, and first determines whether there is a water flow signal. When there is no water flow signal, the water heater is restarted.

[0153] When there is a water flow signal, the water flow information in the water heater is determined based on the water flow signal, and it is judged whether the water flow information is greater than AL / min. If the water flow information is greater than AL / min, the fan is started and the water heater burns normally.

[0154] If the water flow information is less than AL / min, the fan will start at the minimum wind speed to pre-clean the water heater, and determine whether the duration of the water flow in the water heater exceeds T based on the water flow information. If the duration does not exceed T, the fan will be turned off and wait for the next water flow signal.

[0155] If the duration exceeds T, it is further determined whether there is wind pressure outside the water heater. If there is external wind pressure, the specific external wind pressure information is determined, and the fan is increased to the corresponding wind pressure-resistant speed, and the water heater burns normally.

[0156] If there is no external wind pressure, the fan runs at the preset speed and the water heater burns normally.

[0157] The present invention adopts low-speed post-cleaning, extends the time of post-cleaning, and adds wind pressure resistance judgment logic during the post-cleaning time to judge whether there is external wind pressure. Since the wind speed adopted in post-cleaning is relatively low and the duration is relatively long, it is easy to make a correct judgment, and in the subsequent ignition, consider whether to increase the wind speed to improve the wind pressure resistance, so that the water heater can adapt to the changes in external wind pressure and maintain stable combustion and efficient operation of the water heater when external wind pressure exists.
