Therefore, temperature fluctuations can be reduced or avoided, the constant temperature effect of the water heater can be improved, and the user experience can be improved.

Specifically, as shown in
A step S401 of determining whether currently required load is within a common load range obtained in advance or not in the case that that a first preset condition is met.
The control method in this embodiment can be applied to a controller in the gas water heating device. The gas water heating device may further comprise a burning device which includes at least two groups of burners.
In this step, the controller can determine whether the currently required load is within the common load range obtained in advance or not in the case that that a first preset condition is met. In this step, the first preset condition may include that a water use signal from a user is received, at that time the controller can determine whether the currently required load is within the common load range obtained in advance or not.
The currently required load can be thermal load required at the current moment. The controller can obtain incoming water temperature, outgoing water temperature and incoming water flow volume at the current moment. Thereafter, the currently required load can be determined based on the incoming water temperature, the set temperature and the incoming water flow volume at the current moment. In an embodiment, the gas water heating device may further comprise a memory from which the controller may obtain the incoming water temperature, the set temperature, and the incoming water flow volume.
In an embodiment, the gas water heating device may comprise a temperature sensor and a flow volume sensor. The temperature sensor can be used to detect the incoming water temperature and the outgoing water temperature and send the detected incoming water temperature and outgoing water temperature to the memory to be stored. The gas water heating device may further comprise an input device which is used by the user to input the set temperature, mode and other data. The memory can also be used to store data such as the set temperature input by the user. The flow volume sensor can detect the incoming water flow volume or the outgoing water flow volume, and send the detected incoming water flow volume or outgoing water flow volume to the memory to be stored.
In this embodiment, the common load range may be obtained in advance. After obtaining the common load range, the controller can determine whether the currently required load is within the common load range or not.
In an embodiment, the common load range may be stored in the memory of the gas water heating device, from which the controller may obtain the common load range.
In another embodiment, the common load range may be stored in a cloud server in association with a user ID or a device ID. In this embodiment, the gas water heating device may further comprise a communication module through which the controller can obtain the common load range from the cloud server. For example, the controller can send an obtaining request to the cloud server through the communication module. The obtaining request can include the user ID or the device ID. The controller can receive the corresponding common load range from the cloud server through the communication module.
The common load range can be determined according to the water use data when the user uses the gas water heating device, and is used to represent a load range when the user uses the gas water heating device at a high use frequency or for a long use time.
In an embodiment, the user's water use data during a preset period can be obtained, and the load data at each of a plurality of moments within a preset period can be determined based on the user's water use data. Thereafter, the common load range can be determined based on the load data at each of the plurality of moments.
In an exemplary embodiment, the user's common load range can be determined based on an average value of the load data. For example, the load data with too small and too large load values can be filtered out first, the data that the continuous time of water use is less than a preset time can be filtered out, and the data that the water use volume per unit time is less than a preset water use volume can be filtered out, to obtain the screened load data. The load average value of the screened load data can be calculated, and the common load range of users can be determined based on the load average value. For example, the load range span K can be set in advance. After the load average value P is calculated, the common load range can be determined as [P−K/2, P+K/2].
In another exemplary embodiment, after the screened load data is obtained by filtering the data as described above, a load data curve graph can be generated based on the screened load data at each of the plurality of moments. The horizontal axis of the load data curve graph may denote time, and the vertical axis thereof may denote load value. The load range span can be set in advance according to the power range of each of at least two groups of burners of the gas water heating device. Thereafter, the load data curve graph is intercepted by using two straight lines parallel to the horizontal axis (the distance between the two straight lines is the load range span), to obtain a plurality of curve segments located between the two straight lines, and the corresponding time duration of the plurality of curve segments is determined. Multiple times of interception are made by moving the two curves along the longitudinal axis, and the common load range is determined according to the time durations obtained by multiple times of interception.
In an embodiment, the total time durations corresponding to multiple curve segments obtained in each interception can be determined, to obtain a plurality of total time durations, and the load range corresponding to the longest total duration can be determined as the common load range.
In another embodiment, the maximum of the plurality of time durations corresponding to the multiple curve segments obtained in each interception can be taken as the corresponding time duration in this interception, the plurality of time durations corresponding to multiple times of interception can be obtained, and the load range corresponding to the longest time duration is determined as the common load range.
A step S402 of, if it is so, controlling a burner or burner combination corresponding to a common segment to conduct burning; the power range corresponding to the common segment comprises the common load range.
The common segment may correspond to one or more groups of burners of at least two groups of burners of the burning device. After the common load range is obtained, the common segment corresponding to the common load range can also be obtained.
When it is determined that the currently required load is within the common load range obtained in advance, the controller can control a burner or burner combination corresponding to the common segment to conduct burning. The power range corresponding to the common segment comprises the common load range, that is, the common load range is within the power range corresponding to the common segment.
Each time the user starts to use water, in the case that the currently required load is within the common load range obtained in advance, a burner or burner combination corresponding to a common segment can be controlled through the control method of a gas water heating device in the present application to conduct burning. Because the power range corresponding to the common segment comprises the common load range, the required load when the user's water demand or water use environment changes may still be within the common load range. In this way, the demand can be satisfied only by regulating fire power by a gas proportional valve, without the need for segment switching operation. Therefore, temperature fluctuations can be reduced or avoided, the constant temperature effect of the water heater can be improved, and the user experience can be improved.
In the initial stage of use after installation of the gas water heating device, because the user's water usage habits have not been learned, the user's common load range and the corresponding common segment cannot be obtained. Therefore, in some embodiments of the present specification, the control method of the gas water heating device may further comprise: controlling the burning device to conduct burning in a preset segmented mode in the case that the common load range corresponding to the gas water heating device is not obtained.
In the initial stage of use after installation, the preset segmented mode can be stored in the gas water heating device. The preset segmented mode can include a plurality of segments, each segment can correspond to at least one group of burners, and each segment corresponds to a power range. In the case that the common load range is not obtained, the controller can control the burning device to conduct burning in a preset segmented mode. In an embodiment, the controller may, according to the currently required load, determine a first segment corresponding to the currently required load from the plurality of segments in the preset segmented mode, and control the burner or burner combination corresponding to the first segment to conduct burning. The power range corresponding to the first segment can include the currently required load. In the case that subsequent thermal load demand changes, whether the first segment can meet the demand is judged, and if it is so, the fire power can be controlled by regulating the opening degree of the proportional valve of the gas water heating device, without segment switching. Otherwise, segment switching is performed according to the preset segmented mode.
In the initial stage of use after installation of the gas water heating device, in order to determine the user's common load range, the user's water use data in a preset period can be recorded. Therefore, in some embodiments of this specification, the control method of the gas water heating device may further comprise: recording user's water use data of the gas water heating device in a preset period in the case that the common load range corresponding to the gas water heating device is not obtained; and determining the common load range based on the user's water use data in the preset period.
In this embodiment, the preset period can be set according to the actual requirements. For example, the preset period can be one day, one week, one month, or one quarter, etc. In this embodiment, the user's water use data in the preset period can include the incoming water temperature, the set temperature, and incoming water flow volume at a plurality of moments in the preset period. The load value at the plurality of moments in the preset period can be calculated to obtain load data in the preset period based on the incoming water temperature, the set temperature, and the incoming water flow volume at the plurality of moments in the preset period. Thereafter, the common load range can be determined based on the load data in the preset period.
In another embodiment, considering that the set temperature generally remains constant or fluctuates little in the preset period, the user's water use data in the preset period may include the set temperature at a certain moment in the preset period, as well as the incoming water temperature and the incoming water flow volume at the plurality of moments in the preset period. The load value at the plurality of moments in the preset period can be calculated to obtain load data in the preset period based on the set temperature at a certain moment, as well as the incoming water temperature and the incoming water flow volume at the plurality of moments in the preset period. Thereafter, the common load range can be determined based on the load data in the preset period.
In a further embodiment, considering that the set temperature generally remains constant or fluctuates little in the preset period, and the incoming water temperature changes little in the preset period, the user's water use data in the preset period may include the set temperature and the incoming water temperature at a certain moment in the preset period, as well as the incoming water flow volume at the plurality of moments in the preset period. In an embodiment, the load value at the plurality of moments in the preset period can be calculated to obtain load data in the preset period based on the set temperature and the incoming water temperature at a certain moment, as well as the incoming water flow volume at the plurality of moments in the preset period. Thereafter, the common load range can be determined based on the load data in the preset period. In another embodiment, the common incoming water flow volume can be determined based on the incoming water flow volume at the plurality of moments in the preset period. Thereafter, the common load range can be determined according to the common incoming water flow volume as well as the set temperature and the incoming water temperature at a certain moment.
By recording the user's water use data of the user using the gas water heating device in the preset period, the user's water use habits can be learned. The common load range of the gas water heating device is determined based on the user's water use habits, and then the gas water heating device is controlled to conduct burning based on the common load range. Therefore, temperature fluctuations can be reduced or avoided, the constant temperature effect of the water heater can be improved, and the user experience can be improved.
In order to improve the accuracy of the common load range, the obviously abnormal user's water use data can be filtered out when the common load range is determined according to the user's water use data. Therefore, in some embodiments of the present specification, determining the common load range based on the load data in the preset period, may include: screening out load data satisfying a third preset condition from the load data in the preset period; determining the common load range based on the screened-out load data.
In this embodiment, the third preset condition includes at least one of the following: the water use time duration is longer than the preset time period; a load value is within a preset load range; a water incoming volume is within a preset water incoming volume range; a temperature difference changes below a preset temperature difference; the temperature difference is a difference between the set temperature and incoming water temperature. By screening out the load data that the water use time duration is longer than the preset time period, the load data that the water use time duration is too short can be filtered out. By screening out the load data that the load value is within a preset load range, the load data that the load is abnormally high or low can be filtered out. By screening out the load data that a temperature difference changes below a preset temperature difference, the load data that the temperature difference is too large or too small can be filtered out. By screening out the load data that the water incoming volume is within the preset water incoming volume range, the load data that the water incoming volume is too large or too small can be filtered out. After screening, the common load range can be determined based on the screened-out load data. In this way, the accuracy of the common load range can be improved.
Considering that the load difference in different time periods may be large, due to the difference in a temperature difference or water use volume, etc., the common load ranges in different time periods, such as day and night, weekdays and holidays, different seasons, and etc., are different. Therefore, in some embodiments of the present specification, determining the common load range based on the load data in the preset period, may include: dividing the preset period into a plurality of time periods; determining a common load range corresponding to each of the plurality of time periods based on load data in each of the plurality of time periods.
After obtaining the user's water use data in the preset period, the user's water use data in the preset period can be divided according to different time periods. In an embodiment, the user's water use data in the preset period may be divided into first user's water use data and second user's water use data. The first user's water use data is the user's water use data in a first time period in the preset period. The second user's water use data is the user's water use data in a second time period in the preset period. For example, the first time period can be from 8:00 am to 8:00 pm, and the second time period can be from 8:00 pm to 8:00 am. For another example, the first time period can be a working day and the second time period can be a holiday.
In another embodiment, the user's water use data in the preset period may be divided into first user's water use data, second user's water use data and third user's water use data. The first user's water use data is the user's water use data in a first time period in the preset period. The second user's water use data is the user's water use data in a second time period in the preset period. The third user's water use data is the user's water use data in a third time period in the preset period. For example, the first time period can be from 8:00 am to 6:00 pm, the second time period can be from 6:00 pm to 10:00 pm, and the third time period can be from 10:00 pm to 8:00 am. For another example, the first time period is spring and autumn, the second time period is summer, and the third time period is winter. It can be understood that the time period division described above is only illustrative, and may adopt an appropriate way according to the actual water use environment or user's water use habits.
After the user's water use data in the preset period is divided into the user's water use data corresponding to each of the plurality of time periods, the common load range corresponding to each time period can be calculated using the method of calculating the common load range in the above embodiment, to obtain a plurality of common load ranges. In the above way, the common load range can be calculated for different time periods, making the common load range be more targeted.
Further, because the common load range may include the common load range corresponding to each of the plurality of time periods, obtaining a common load range corresponding to the gas water heating device may include: determining a target time period corresponding to the current moment; obtaining a common load range of the gas water heating device in the target time period.
Specifically, the target time period corresponding to the current moment can be determined, and thereafter the common load range of the gas water heating device in the target time period is obtained. The applicability of the common load range obtained in this way is stronger, which can improve the constant temperature effect of the water heater.
After the common load range is determined, the common segment corresponding to the common load range can be determined. The power range corresponding to the common segment here can include the common load range. The common load range can be associated with the common segment and stored in a local memory or a cloud server. Therefore, in some embodiments of this specification, the control method of the gas water heating device may further comprise: obtaining the power range corresponding to each segment of a plurality of segments in the preset segmented mode in the case that the common load range is determined; generating the common segment based on the common load range in the casing that the power range corresponding to each segment does not include the common load range.
A preset segmented mode can be stored in advance in the gas water heating device. The preset segmented mode may include a plurality of segments. Each of the plurality of segments can correspond to one group of burners or combination of a plurality of groups of burners. The gas water heating device may further store the power range corresponding to each segment of a plurality of segments in advance. The power range corresponding to each segment of a plurality of segments in the preset segmented mode can be obtained in the case that the common load range is determined. Whether the power range corresponding to each segment includes the common load range or not is determined. The common segment can be generated based on the common load range in the case that the power range corresponding to each segment does not include the common load range. The common segment can correspond to one group of burners or combination of a plurality of groups of burners. In the above way, in the case that there is no segment containing the common load range in the preset segmented mode, at least two groups of burners can be recombined based on the common power range to generate a new segment to obtain the common segment.
Further, in some embodiments of the present specification, any of at least one of the plurality of segments can be determined as the common segment in the case that the power range of the at least one of the plurality of segments includes the common load range. In this embodiment, in the case that there is at least one segment containing the common load range in the preset segmented mode, any of at least one of the plurality of segments can be determined as the common segment.
Optionally, in the case that the power range of at least one segment of the plurality of segments includes the common load range, a plurality of common segments can be obtained by taking all of the plurality of segments in the at least one segment as the common segments. In this way, when subsequently controlling the burners corresponding to the common segments to conduct burning, the plurality of common segments can be used in turn to avoid the failure problem caused by long-term heating of the local area of the heat exchanger corresponding to the burner of the same common segment when conducting burning only in the same common segment, and thus the service life of the gas water heating device can be extended.
Optionally, in some embodiments of the present specification, a segment with a maximum upper power limit among at least one of the plurality of segments is determined as the common segment in the case that the power range of the at least one of the plurality of segments includes the common load range. The greater the upper power limit of the segment is, the greater the number of fire grate burners contained in the burner or burner combination corresponding to the segment is. In this way, during burning, the lower the load of a single fire grate burner is, the lower the rotating speed of the fan is, and correspondingly the lower the noise is. By using the segment having the maximum upper power limit and containing the common load range as the common segment, the noise of the gas water heating device can be reduced and the user experience can be improved.
Optionally, in some embodiments of the present specification, a segment with a maximum power range span among at least one of the plurality of segments is determined as the common segment in the case that the power range of the at least one of the plurality of segments includes the common load range. The greater the power range span of the common segment is, the greater the probability that the thermal load required when the subsequent user's water use demand changes is still in the common segment. Correspondingly, the number of times of subsequent segment switching can be reduced, which thus can reduce temperature fluctuations, improve the constant temperature effect, and improve the user's constant temperature experience.
Considering that the user's water use habits and the user's water use environment may change, the common load range will change accordingly, thus the common load range can be updated regularly. Therefore, in some embodiments of this specification, the control method of the gas water heating device may further comprise: recording, the user's water use data of the gas water heating device in a preset period, once every preset time period to update the common load range. By updating the common load range regularly, it is possible to avoid the failure of the common load range caused by changes in the user's water use habits or water use environment. By updating the common load range in real time, the problem of large temperature fluctuation caused by segment switching can be further reduced, and the constant temperature effect of the gas water heating device can be improved.
The common load range depends mainly on the user's water use habits and/or the user's water use environment, thus the common load range can be updated in case of large changes in relevant data. Therefore, in some embodiments of this specification, the control method of the gas water heating device may further comprise: recording the user's water use data of the gas water heating device in the preset period starting from a current moment in the case that a second preset condition is met, to update the common load range.
In this embodiment, the second preset condition may include at least one of the following: a temperature difference changes beyond a first preset temperature difference range; the temperature difference is a difference between the set temperature and incoming water temperature; water use volume changes beyond a preset water volume range. When the temperature difference changes greatly, the user set temperature may change greatly or the incoming water temperature changes greatly due to changes in the ambient temperature. The change in the water use volume can refer to a large change in the total water use volume of the user within a specified time period. It can be understood that the second preset condition can also include other conditions, for example, the change of the incoming water flow volume exceeds the preset flow volume, the change of water pressure exceeds the preset pressure, etc. In this embodiment, the user's water use data in the preset period is re-recorded to update the common load range in the case that the user's water use habit or water use environment changes greatly, which can avoid the failure of the common load range due to changes of the user's water use habit or the user's water use environment, improve the applicability of the common load range, and then improve the constant temperature effect of the gas water heating device.
In some embodiments of the present specification, in the case that it is determined that the currently required load is not within the common load range obtained in advance, the control method of the gas water heating device may further comprise: controlling the burning device to conduct burning in a preset segmented mode.
In this embodiment, the preset segmented mode can include a plurality of segments, each segment can correspond to at least one group of burners. In the case that the common load range is not obtained, the controller can control the burning device to conduct burning in a preset segmented mode. In an embodiment, the controller may, according to the currently required load, determine the first segment corresponding to the currently required load, and control the burner or burner combination corresponding to the first segment to conduct burning. The power range corresponding to the first segment can include the currently required load. In the case that subsequent thermal load demand changes, whether the first segment can meet the demand is judged, and if it is so, the fire power can be controlled by regulating the opening degree of the proportional valve of the gas water heating device, without segment switching. Otherwise, segment switching is performed according to the preset segmented mode. In this embodiment, burning is controlled in a conventional mode in the case that the currently required load is not in the common load range.
When the gas water heating device conducts burning in a preset segmented mode, whether the currently required load is in the common load range or not can be re-determined when the thermal demand changes, and if it is so, the burning device is controlled to switch to the burner or burner combination corresponding to the common segment to conduct burning. Therefore, in some embodiments of this specification, the control method of the gas water heating device may further comprise: when controlling the burning device to conduct burning in a preset segmented mode, determining whether the currently required load is within the common load range or not in the case that a fourth preset condition is met; controlling the burning device to switch to the burner or burner combination corresponding to the common segment to conduct burning in the case that it is determined that the currently required load is within the common load range.
In this embodiment, the fourth preset condition includes at least one of the following: incoming water flow volume or outgoing water flow volume changes beyond a first preset flow volume range; a temperature difference changes beyond a second preset temperature difference range; the temperature difference is a difference between the set temperature and incoming water temperature. In the case of large change in the incoming water flow volume, large change in the outgoing water flow volume or large change in the temperature difference, the currently required load can be re-determined, and whether the currently required load is in the common load range or not can be rejudged, and if it is so, switching to the common segment to conduct burning, which can avoid subsequent frequent segment switching and improve the constant temperature effect.
In order to meet the user's water use demand, when controlling the burner or burner combination corresponding to the common segment to conduct burning, whether the thermal demand changes greatly or not can be monitored, and if it is so, it is necessary to re-determine whether the currently required load is in the common load range or the power range corresponding to the common segment. Therefore, in some embodiments of this specification, the control method of the gas water heating device may further comprise: when controlling the burner or burner combination corresponding to the common segment to conduct burning, in the case that the fifth preset condition is met, determining whether the currently required load is in the common load range or the power range corresponding to the common segment or not; controlling an opening degree of a gas proportional valve of the gas water heating device based on the currently required load in the case that it is determined that the currently required load is in the common load range or the power range corresponding to the common segment. In the case that the currently required load after the thermal demand changes is still in the common load range or the power range corresponding to the common segment, the fire power can be regulated to meet the user's need by regulating the opening degree of the gas proportional valve to avoid temperature fluctuation caused by segment switching.
In this embodiment, the fifth preset condition includes at least one of the following: incoming water flow volume or outgoing water flow volume changes beyond a second preset flow volume range; a temperature difference changes beyond a third preset temperature difference range; the temperature difference is a difference between the set temperature and incoming water temperature. It can be understood that other fifth preset conditions can be set as needed.
Further, in some embodiments of this specification, the control method of the gas water heating device may further comprise: controlling the burning device to switch to conduct burning in a preset segmented mode in the case that it is determined that the currently required load is not in the common load range or the power range corresponding to the common segment. In the case that the currently required load after the thermal demand changes exceeds the common load range or exceeds the power range corresponding to the common segment, the burning device can be controlled to switch to an appropriate segment in the preset segmented mode to conduct burning. In this embodiment, the corresponding second segment can be selected from the preset segmented mode according to the currently required load redetermined after the thermal demand changes, and the burning device can be switched from the common segment to the second segment to conduct burning. The power range corresponding to the second segment can include the redetermined currently required load. In this embodiment, in the case that the currently required load after the thermal demand changes exceeds the power range of the common segment, the segment switching operation can be performed to meet the user's demand.
In some embodiments of the present specification, the gas water heating device may further comprise: at least two gas transportation channels that can be independently opened and closed. The at least two gas transportation channels are arranged one-to-one correspondingly to at least two groups of burners. The at least two groups of burners include a first group of burners and a second group of burners.

Further, in some embodiments of the present specification, the at least two groups of burners may further include a third group of burners located between the first group of burners and the second group of burners.

Specifically, after the third group of burners are ignited, the first group of burners and/or the second group of burners may be controlled to maintain burning or to be closed depending on whether the common segment contains the first group of burners and/or the second group of burners.
Further, in some embodiments of the present specification, the at least two groups of burners may further include a third group of burners and a fourth group of burners located between the first group of burners and the second group of burners. The third group of burners can be adjacent to the first group of burners, and the fourth group of burners can be adjacent to the second group of burners. The third group of burners and the fourth group of burners can be ignited respectively by the first group of burners and the second group of burners in a burning state. The first group of burners can be ignited also by the third group of burners in the burning state. The second group of burners can be ignited also by the fourth group of burners in the burning state.

Specifically, after the third group of burners and the fourth group of burners are ignited, the first group of burners and/or the second group of burners may be controlled to maintain burning or to be closed depending on whether the common segment contains the first group of burners and/or the second group of burners.
