[0020] The embodiments of the present application are described in detail below, and the embodiments of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0021] Please also read Figure 1 and Figure 2 A control method provided in an embodiment of the present application is used for a water heater 100. The water heater 100 includes a fan 10 and a wind pressure sensor 20, and the control method includes:

[0022] Step 01: Obtain the current rotation speed value of the fan 10 and the current wind pressure value of the wind pressure sensor 20;

[0023] Step 02: Determine the current altitude information according to the current rotation speed value and the current wind pressure value;

[0024] Step 03: Adjust the working state of the fan 10 according to the altitude information.

[0025] Please refer again Figure 2The embodiment of the present application also provides a water heater 100, and the control method of the embodiment of the present application can be implemented by the water heater 100 of the embodiment of the present application. The water heater 100 includes a fan 10, a wind pressure sensor 20 and a controller 30, and the controller 30 is electrically connected to the fan 10 and the wind pressure sensor 20. Among them, step 01, step 02 and step 03 can all be implemented by the controller 30, that is, the controller 30 is used to: obtain the current speed value of the fan 10 and the current wind pressure value of the wind pressure sensor 20; determine the current altitude information according to the current speed value and the current wind pressure value; adjust the working state of the fan 10 according to the altitude information.

[0026] The control method and water heater 100 of the implementation mode of the present application can use the fan 10 and the wind pressure sensor 20 to determine the altitude, and adjust the working state of the fan 10 according to the determined altitude to achieve the purpose of self-adaptation at different altitudes, thereby solving the problems of false alarm and backfire that are prone to occur in the water heater 100 in high altitude areas.

[0027] Specifically, the water heater 100 is a gas water heater, which is an electrical appliance supported by the combustion theory. The fan 10 is used to deliver air, and the water heater 100 may also include a gas valve. The water heater 100 mainly relies on the air delivered by the fan 10 and the gas entering the gas valve to mix and burn. In order to ensure the combustion effect, the ratio of the amount of air to the amount of gas that the user feels must be within a certain range.

[0028] It is worth mentioning that in the relevant technology, the production and design of gas water heaters are concentrated in low-altitude areas. It is understandable that the gas water heaters are tested against the background of the environment in low-altitude areas. When the gas water heater is sold to high-altitude areas, due to the low oxygen content in the air and the low atmospheric pressure in high-altitude areas, the ratio of the amount of air delivered to the amount of gas entering the gas valve when the fan is working at a speed of even 0.000 in low-altitude areas is difficult to be within the range, resulting in a large difference and change in the combustion characteristics of the gas water heater in high-altitude areas compared with low-altitude areas. Due to the change in the combustion characteristics of the water heater, backfire, excessive smoke, insufficient load and other problems may occur when using the gas water heater, causing inconvenience to the user and even potential safety hazards. The water heater 100 of the embodiment of the present application can adapt to different altitudes, and the controller 30 can obtain the current speed value of the fan 10 and the current wind pressure value of the wind pressure sensor 20, and then determine the current altitude information. The rotation speed of the fan 10 is adjusted in combination with the current altitude information so that the ratio of the amount of air delivered by the fan 10 to the amount of gas entering the gas valve is within a certain range, thereby ensuring the combustion efficiency and improving the safety of the water heater 100, thereby ensuring the user experience.

[0029] In some embodiments, the fan 10 may include a motor, a fan wheel and a fan housing. The rotation of the motor drives the fan wheel to rotate. The fan wheel and the fan housing work together to form a negative pressure at the air inlet to inhale air. In this way, the air contains oxygen, and the fan 10 can provide the water heater 100 with oxygen required for combustion, remove smoke after combustion, and resist wind pressure.

[0030] It is worth mentioning that, in one embodiment, the water heater 100 is a balanced gas water heater, and the load of the balanced gas water heater is controlled by the rotation speed of the fan 10. For example: in low altitude areas, the rotation speed value of the fan 10 of the balanced gas water heater can reach the rated load at 5000r / min. However, in high altitude areas, the rotation speed value of the fan 10 of the same balanced gas water heater may not reach the rated load when it is 5000r / min. In this way, the rotation speed value of the fan 10 can be used to set and judge the size of the load. If you want to reach the rated load, you need to increase the rotation speed of the fan 10.

[0031] The wind pressure sensor 20 can be used to detect the wind pressure value generated by the fan 10 when the water heater 100 is working, and the wind pressure value can be used to determine the combustion condition of the water heater 100. A wind pressure protection point can also be set to prevent wind blocking and blowing.

[0032] In one embodiment, the speed value of the fan 10 of the water heater 100 ranges from 1000r / min to 8000r / min. It is understandable that, when the current speed value of the fan 10 is higher, the current wind pressure value obtained by the wind pressure sensor 20 is greater. The user can use the water heater 100 in Foshan (the altitude of Foshan is 8 meters, the atmospheric pressure is 101kPa, and Foshan is a low altitude area). The user can also use the water heater 100 in Kunming (the altitude of Kunming is 1891 meters, and the atmospheric pressure is 80.8kPa).

[0033] Specifically, when the water heater 100 is used in Foshan, the controller 30 obtains a current rotation speed value of 8000 r / min and a current wind pressure value of 1500 Pa. Thus, the controller 30 can determine that the current altitude information is 8 meters based on 8000 r / min and 1500 Pa; or it can determine that the current altitude information is a low altitude area based on 8000 r / min and 1500 Pa, which is not limited here. Finally, the working state of the fan 10 is adjusted in combination with the altitude data.

[0034] It is worth mentioning that if the altitude where the water heater 100 is manufactured and designed is not much different from the inferred altitude information, for example, if the altitude where the water heater 100 is manufactured and designed is 0 meters, the altitude information is 8 meters; if the altitude where the water heater 100 is manufactured and designed is a low altitude area, the altitude information is a low altitude area. The ratio of the amount of air delivered by the fan 10 to the amount of gas entering the gas valve can be within a certain range, and the water heater 100 can be used without adjusting the working state of the fan 10 (i.e., using the current speed value).

[0035] When the water heater 100 is used in Kunming, the controller 30 obtains the current speed value of 8000r / min and the current wind pressure value of 1250Pa. Thus, the controller 30 can determine that the current altitude information is 1891 meters based on 8000r / min and 1250Pa; or it can determine that the current altitude information is a high altitude area based on 8000r / min and 1500Pa, which is not limited here. Finally, the working state of the fan 10 is adjusted according to the altitude information.

[0036] In one embodiment, under the standard atmospheric pressure when the water heater 100 is produced and designed, the standard speed value is 8000r / min, and the corresponding standard wind pressure value is 1500Pa. However, when the water heater 100 is actually used, the current wind pressure value obtained by the wind pressure sensor 20 is 1250Pa, and the current wind pressure value 1250Pa is offset from the standard wind pressure value 1500Pa. Therefore, it can be inferred that the current use environment is a high altitude area, and the working state of the fan 10 is adjusted in combination with the altitude information (i.e., the speed value of the fan 10 is increased) to use the water heater 100.

[0037] It should be noted that the above examples and specific numerical values ​​are for the convenience of explaining the implementation of the present application and should not be construed as limiting the scope of protection of the present application.

[0038] See also Figure 3 In some embodiments, step 01 includes:

[0039] Step 011: When the water heater 100 is not supplied with gas or water, a first rotation speed value of the fan 10 and a first wind pressure value of the wind pressure sensor 20 are obtained;

[0040] Step 012: When the water heater 100 is powered by gas and water, a second rotation speed value of the fan 10 and a second wind pressure value of the wind pressure sensor 20 are obtained;

[0041] Step 02 includes:

[0042] Step 021: Determine first current altitude information according to the first rotation speed value and the second rotation speed value;

[0043] Step 022: Determine second current altitude information according to the first wind pressure value and the second wind pressure value;

[0044] Step 023: Determine the current altitude information according to the first current altitude information and the second current altitude information.

[0045] The control method of the embodiment of the present application can be implemented by the water heater 100 of the embodiment of the present application. Specifically, the water heater 100 includes a controller 30, and steps 011, 012, 021, 022, and 023 can be implemented by the controller 30, that is, the controller 30 is used to: obtain the first speed value of the fan 10 and the first wind pressure value of the wind pressure sensor 20 when the water heater 100 is not connected to gas and water; obtain the second speed value of the fan 10 and the second wind pressure value of the wind pressure sensor 20 when the water heater 100 is connected to gas and water; determine the first current altitude information according to the first speed value and the second speed value; determine the second current altitude information according to the first wind pressure value and the second wind pressure value; determine the current altitude information according to the first current altitude information and the second current altitude information.

[0046] See also Figure 4 In one embodiment, when the water heater 100 is not connected to gas and water, the controller 30 can control the fan 10 and the wind pressure sensor 20 to turn on. After the fan 10 and the wind pressure sensor 20 are turned on, the controller 30 can obtain the first speed value of the fan 10 as 7000r / min and the first wind pressure value of the wind pressure sensor 20 as 1300Pa, so that the first current altitude information can be determined to be 10 meters, which is a low altitude area. When the water heater 100 is connected to gas and water, the controller 30 can control the fan 10 and the wind pressure sensor 20 to turn on again. After the fan 10 and the wind pressure sensor 20 are turned on for the second time, the second speed value of the fan 10 can be obtained as 8000r / min and the second wind pressure value of the wind pressure sensor 20 can be obtained as 1500Pa, so that the first current altitude information can be determined to be 11 meters, which is a low altitude area. The first current altitude information and the second current altitude information can be combined to determine that the current altitude is a low altitude area. In this way, when the water heater 100 is powered by gas and water, the second current altitude information obtained by turning on the fan 10 and the wind pressure sensor 20 for the second time can be used to check the result and correct the first current altitude information. Combining the two altitude information can avoid misjudgment and improve the user experience.

[0047] It should be noted that the above examples and specific numerical values ​​are for the convenience of explaining the implementation of the present application and should not be construed as limiting the scope of protection of the present application.

[0048] See also Figure 5In some embodiments, step 023 includes:

[0049] Step 0231: When the difference between the first current altitude information and the second current altitude information is within a preset difference range, determine that the second current altitude information is the current altitude information.

[0050] The control method of the embodiment of the present application can be implemented by the water heater 100 of the embodiment of the present application. Specifically, the water heater 100 includes a controller 30, and step 0231 can be implemented by the controller 30, that is, the controller 30 is used to: when the difference between the first current altitude information and the second current altitude information is within a preset difference range, determine that the second current altitude information is the current altitude information.

[0051] In one embodiment, when the water heater 100 is not connected to gas and water, the controller 30 can control the fan 10 and the wind pressure sensor 20 to turn on. After the fan 10 and the wind pressure sensor 20 are turned on, the first speed value of the fan 10 is 8000r / min, the first wind pressure value of the wind pressure sensor 20 is 1497Pa, and the first current altitude information is determined to be 8.11 meters, which is a low altitude area. When the water heater 100 is connected to gas and water, the controller 30 can control the fan 10 and the wind pressure sensor 20 to turn on again. After the fan 10 and the wind pressure sensor 20 are turned on for the second time, the second speed value of the fan 10 is 8000r / min, the second wind pressure value of the wind pressure sensor 20 is 1499Pa, and 8.14 meters. The difference between the first current altitude information and the second current altitude information is within the preset difference range, so the second current altitude information, i.e., 8.14 meters, can be used as the current altitude information. The second current altitude information determined when gas and water are turned on is more accurate as the current altitude information, and can improve the user experience.

[0052] See also Figure 6 In some embodiments, the control method further comprises:

[0053] Step 04: When the water heater 100 is in the altitude determination state, the fan 10 and the wind pressure sensor 20 are turned on.

[0054] The control method of the embodiment of the present application can be implemented by the water heater 100 of the embodiment of the present application. Specifically, the water heater 100 includes a controller 30, and step 04 can be implemented by the controller 30, that is, the controller 30 is used to: turn on the fan 10 and the wind pressure sensor 20 when the water heater 100 is in the altitude determination state.

[0055] In some embodiments, the water heater 100 includes an altitude determination mode, and when the user selects the altitude determination mode, the water heater 100 is in an altitude determination state. The user can select the altitude determination mode by pressing the altitude determination mode button; or the altitude determination mode can be automatically entered after the water heater 100 is turned on, which is not limited here. When the water heater 100 is in the altitude determination state, the fan 10 and the wind pressure sensor 20 are automatically turned on to obtain the current speed value and the current wind pressure value, and the current altitude information is determined based on the current speed value and the current wind pressure value, and the controller then adjusts the working state of the fan 10 based on the altitude information. In this way, the water heater 100 can be made more intelligent and more user-friendly, improving the user experience.

[0056] See also Figure 7 In some embodiments, step 01 further includes:

[0057] Step 013: When the fan 10 is turned on for a preset time, the current rotation speed value and the current wind pressure value are obtained.

[0058] The control method of the embodiment of the present application can be implemented by the water heater 100 of the embodiment of the present application. Specifically, the water heater 100 includes a controller 30, and step 013 can be implemented by the controller 30, that is, the controller 30 is used to: obtain the current speed value and the current wind pressure value when the fan 10 is turned on for a preset time.

[0059] In this way, it can be ensured that the current rotation speed value and the current wind pressure value obtained are more valuable for reference, thereby improving the accuracy of the current altitude information.

[0060] In one embodiment, the preset time length may be 30 seconds, and the current speed value and the current wind pressure value are obtained when the fan 10 is turned on for 30 seconds. In this way, the fan 10 can stably operate at a certain speed value during the preset time length, which can improve the accuracy of the corresponding current altitude information. In another embodiment, the preset time length includes a preset working condition, and the current speed value and the current wind pressure value are obtained when the fan 10 is turned on to the preset working condition. When the fan 10 is in the preset working condition, it can stably operate at a certain speed value, which can improve the accuracy of the corresponding current altitude information.

[0061] See also Figure 8 In some embodiments, step 02 includes:

[0062] Step 024: Determine the current altitude information according to the current rotation speed value, the current wind pressure value and the altitude database, the altitude database includes multiple correspondences, each of which is a one-to-one correspondence between a calibrated rotation speed value, a calibrated wind pressure value and a calibrated altitude information.

[0063] The control method of the embodiment of the present application can be implemented by the water heater 100 of the embodiment of the present application. Specifically, the water heater 100 includes a controller 30, and step 024 can be implemented by the controller 30, that is, the controller 30 is used to: determine the current altitude information according to the current speed value, the current wind pressure value and the altitude database, and the altitude database includes multiple corresponding relationships, each of which is a one-to-one correspondence between a calibrated speed value, a calibrated wind pressure value and a calibrated altitude information.

[0064] In this way, the current altitude information can be quickly determined through the altitude database.

[0065] The altitude database can be obtained through calibration. Specifically, the water heater 100 can be placed in a place that meets the calibration altitude information, the fan 10 can be controlled to rotate, the speed of the fan 10 can be obtained as the calibration speed value, and the wind pressure value of the wind pressure sensor 20 can be obtained as the calibration wind pressure value, so that a corresponding relationship can be obtained, and the water heater 100 can be placed in a place that meets different calibration altitude information, and then multiple corresponding relationships can be obtained through calibration. After obtaining the current speed value and the current wind pressure value, the corresponding current altitude information can be searched in the altitude database.

[0066] See also Fig. 9 In some embodiments, step 024 includes:

[0067] Step 0241: searching the corresponding calibrated speed value in the altitude database according to the current speed value;

[0068] Step 0242: searching the corresponding calibrated wind pressure value in the altitude database according to the current wind pressure value;

[0069] Step 0243: Determine the calibrated altitude information according to the calibrated rotation speed value and the calibrated wind pressure value to serve as the current altitude information.

[0070] The control method of the embodiment of the present application can be implemented by the water heater 100 of the embodiment of the present application. Specifically, the water heater 100 includes a controller 30, and steps 0241, 0242, and 0243 can be implemented by the controller 30, that is, the controller 30 is used to: search for the corresponding calibrated speed value in the altitude database according to the current speed value; search for the corresponding calibrated wind pressure value in the altitude database according to the current wind pressure value; determine the calibrated altitude information according to the calibrated speed value and the calibrated wind pressure value as the current altitude information.

[0071] In this way, the calibrated altitude information can be quickly determined as the current altitude information according to the calibrated rotation speed value corresponding to the current rotation speed value and the calibrated wind pressure value corresponding to the current wind pressure value.

[0072] Specifically, the calibrated speed value that is the same as or close to the current speed value can be searched in the altitude database according to the current speed value, and the calibrated wind pressure value that is the same as or close to the current wind pressure value can be searched in the altitude database according to the current wind pressure value, and then the corresponding calibrated altitude information is determined according to the calibrated speed value and the calibrated wind pressure value as the current altitude information. For example, in one embodiment, the multiple corresponding relationships include a first corresponding relationship and a second corresponding relationship, and the first corresponding relationship is, for example, that the calibrated altitude information is 8 meters, the calibrated speed value is 8000r / min, and the calibrated wind pressure value is 1500Pa; the second corresponding relationship is, for example, that the calibrated altitude information is 1891 meters, the calibrated speed value is 8000r / min, and the calibrated wind pressure value is 1250Pa. When the current calibrated speed value is 8000r / min and the current wind pressure value is 1500Pa, it can be determined by searching that the first corresponding relationship is satisfied. Therefore, the corresponding calibrated altitude information is the current altitude information, that is to say, the current altitude information is 8 meters; when the current calibrated speed value is 8000r / min and the current wind pressure value is 1250Pa, it can be determined by searching that the second corresponding relationship is satisfied. Therefore, the corresponding calibrated altitude information is the current altitude information, that is to say, the current altitude information is 1891 meters.

[0073] See also Fig.10 In some embodiments, step 03 includes:

[0074] Step 031: Determine the target speed value according to the current altitude information and the wind turbine speed database;

[0075] Step 032: Calculate the difference between the target speed value and the current speed value, and adjust the working state of the fan 10 according to the difference.

[0076] The control method of the embodiment of the present application can be implemented by the water heater 100 of the embodiment of the present application. Specifically, the water heater 100 includes a controller 30, and steps 031 and 032 can be implemented by the controller 30, that is, the controller 30 is used to: determine the target speed value according to the current altitude information and the fan speed database; calculate the difference between the target speed value and the current speed value, and adjust the working state of the fan 10 according to the difference.

[0077] In this way, the target speed value that the fan 10 should have can be determined according to the current altitude information, thereby achieving the purpose of self-adaptation at different altitudes and solving the problems of false alarm and backfire that are prone to occur in the water heater 100 at high altitudes.

[0078] Specifically, the fan speed database may include a correspondence between different altitudes and fan speed values. Among them, one altitude may correspond to one fan speed value, for example: the altitude is 10 meters, and the corresponding fan speed value is 7000r / min; the altitude is 2000 meters, and the corresponding fan speed value is 8000r / min. It may also be that an altitude range corresponds to one fan speed value, for example: the high altitude range (such as 1500 meters to 3500 meters), the corresponding fan speed value is 8000r / min; the medium altitude range (such as 100 meters to 1500 meters), the corresponding fan speed value is 7500r / min. The corresponding fan speed value can be determined as the target speed value through the current altitude information and the fan speed database. For example, the current altitude information is 2000 meters, and the corresponding fan speed value can be determined to be 8000r / min as the target speed value. The difference between the target speed value and the current speed value is calculated, and the working state of the fan 10 is adjusted according to the difference. For example, the target speed value is 8000r / min, the current speed value is 5000r / min, and the difference between the target speed value and the current speed value is 3000r / min. If the current speed value is not enough, problems such as backfire, excessive flue gas, and insufficient load may occur. Therefore, the working state of the fan 10 can be adjusted according to the difference, such as increasing the speed of the fan 10, so that the ratio of the air volume delivered by the fan 10 to the gas volume entering the gas valve is within a certain range, thereby ensuring the combustion efficiency, improving the safety of the water heater 100, and thus improving the user experience.

[0079] It should be noted that the above examples and specific numerical values ​​are for the convenience of explaining the implementation of the present application and should not be construed as limiting the scope of protection of the present application.

[0080] The embodiment of the present application further provides a computer-readable storage medium, in which a computer program is stored. When the computer program is executed by a processor, the processor executes the steps of the control method of any of the above embodiments.

[0081] In one embodiment, when the program is executed by a processor, the following control method steps are implemented:
