[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] At present, existing water heaters can be turned on in zero cold water mode, which means that after the water heater is started, it can quickly provide hot water at a constant temperature without the need for preheating. It avoids the problem of traditional gas water heaters needing to discharge a certain amount of cold water when in use, and is energy-saving, environmentally friendly, convenient and practical.

[0027] In order to be more intelligent, the zero cold water mode of the water heater can be self-learned based on the user's usage habits. However, the zero cold water mode of the existing water heater has poor self-learning for users with irregular water usage habits, resulting in a poor user experience.

[0028] Based on this, a control method, device, equipment and storage medium for a water heater provided in an embodiment of the present invention can set a self-learning period, and use the operating data of the water heater whose operating time belongs to the preset self-learning period as historical operating data, thereby enhancing the self-learning effect of the zero cold water mode of the water heater for users with irregular water use habits, thereby improving the user experience.

[0029] To facilitate understanding of this embodiment, a control method for a water heater disclosed in an embodiment of the present invention is first introduced in detail.

[0030] Embodiment 1:

[0031] The embodiment of the present invention provides a control method for a water heater. Figure 1 A flow chart of a water heater control method is shown, and the water heater control method comprises the following steps:

[0032] Step S102, when the water heater is not in the zero cold water mode, if the operation time of the water heater belongs to the preset self-learning period, the operation data of the water heater is obtained as the historical operation data.

[0033] In this embodiment, historical operation data of the water heater can be acquired in advance. When the water heater is not in the zero cold water mode, the operation data of the water heater whose operation time belongs to the preset self-learning period can be used as historical operation data.

[0034] Therefore, in the present embodiment, a self-learning period can be set, and the operating data of the water heater whose operating time belongs to the preset self-learning period can be used as historical operating data, and the operating data of the water heater that does not belong to the self-learning period can be not used as historical operating data, thereby improving the accuracy of the historical operating data, and avoiding the occurrence of self-learning confusion due to irregular water use, thereby enhancing the self-learning effect of the zero cold water mode of the water heater for users with irregular water use habits, thereby improving the user experience.

[0035] Step S104: when the water heater is in the zero cold water mode, if there is historical operation data, the outlet water temperature of the water heater is determined based on the historical operation data.

[0036] When the water heater is in the zero cold water mode and there is historical operation data, this embodiment can determine the outlet water temperature of the water heater based on the historical operation data. Since the historical operation data in this embodiment is the operation data of the water heater whose operation time belongs to the preset self-learning period, the accuracy of determining the outlet water temperature of the water heater based on the historical operation data can be improved, thereby enhancing the self-learning effect of the zero cold water mode of the water heater for users with irregular water use habits, thereby improving the user experience.

[0037] In addition, the various data in the above method provided in this embodiment can be stored in the cloud or on the water heater end, so it can support both networked water heaters and non-networked water heaters, and can ensure that the above method provided in this embodiment can also be used when the network of the water heater is disconnected.

[0038] The embodiment of the present invention provides a control method for a water heater. When the water heater is not in a zero cold water mode, if the operation time of the water heater belongs to a preset self-learning period, the operation data of the water heater is obtained as historical operation data; when the water heater is in a zero cold water mode, if there is historical operation data, the outlet water temperature of the water heater is determined based on the historical operation data. In this method, a self-learning period can be set, and the operation data of the water heater whose operation time belongs to the preset self-learning period is used as historical operation data, thereby enhancing the self-learning effect of the zero cold water mode of the water heater for users with irregular water use habits, thereby improving the user experience.

[0039] Embodiment 2:

[0040] This embodiment provides another water heater control method, which is implemented on the basis of the above embodiment. Figure 2 The flowchart of another water heater control method shown in FIG. 1 includes the following steps:

[0041] Step S202, when the water heater is not in the zero cold water mode, determine the water outlet temperature of the water heater based on the pre-set normal mode; if the operation time of the water heater belongs to the preset self-learning period, obtain the operation data of the normal mode of the water heater as the historical operation data.

[0042] See also Figure 3 A schematic diagram of a water heater control method is shown in FIG. Figure 3 As shown, when the water heater is not in the zero cold water mode, the water heater in this embodiment can be operated in the pre-set common mode. The operation data of the common mode of the water heater whose operation time belongs to the preset self-learning period can be used as the historical operation data, and the operation data of the common mode of the water heater whose operation time does not belong to the preset self-learning period can be used as the historical operation data, thereby improving the accuracy of the historical operation data.

[0043] Step S204: when the water heater is in the zero cold water mode, if there is historical operation data, the outlet water temperature of the water heater is determined based on the historical operation data.

[0044] In some embodiments, when the water heater is in zero cold water mode, determine whether there is historical operating data within a preset time period; if there is historical operating data within the preset time period, determine the average water outlet temperature of the water heater of the historical operating data within the preset time period; and use the average water outlet temperature of the water heater as the water outlet temperature of the water heater.

[0045] like Figure 3 As shown, in this embodiment, the above-mentioned preset time period can be set to 1 week. When the water heater is in the zero cold water mode, it can be determined whether there is historical operation data within 1 week (i.e., within the preset time period). If there is historical operation data within 1 week, the average water outlet temperature of the water heater of the historical operation data within 1 week can be used as the current water outlet temperature of the water heater.

[0046] In some embodiments, if there is no historical operation data within a preset time period, the outlet water temperature of the water heater is determined based on weather information; wherein the weather information includes season information and / or temperature information.

[0047] like Figure 3 As shown, if there is no historical operation data within 1 week, the outlet water temperature of the water heater cannot be determined through the historical operation data. In this embodiment, the outlet water temperature of the water heater can be determined through weather information.

[0048] The perceived temperature is different in different seasons and temperatures, and the outlet water temperature needs to be adjusted appropriately. In this embodiment, weather factors can be taken into account, and the outlet water temperature of the water heater is determined based on weather information such as season information and / or temperature information.

[0049] In this embodiment, if the historical operation data is damaged or deleted, or the user starts the zero cold water mode of the water heater for the first time, there is no historical operation data of the zero cold water mode. At this time, the outlet water temperature of the water heater can be directly determined according to the weather information, and the user is automatically provided with an accurate and comfortable outlet water temperature.

[0050] In some embodiments, it can also be determined whether the water heater is starting the zero cold water mode for the first time; if it is the first time to start the zero cold water mode, the start time of the water heater is set to a preset default time; if it is not the first time to start the zero cold water mode, the start time of the water heater is set to the start time set when the zero cold water mode was started last time.

[0051] like Figure 3 As shown, if it is the first time to start the zero cold water mode, the start time of the water heater can be set to the system default time; if it is not the first time to start the zero cold water mode, the start time of the water heater can be set to the last set start time.

[0052] After determining the final outlet water temperature, the operation of the water heater can be controlled by the outlet water temperature. In some embodiments, if the water heater reaches a preset start time, a preheating operation of the zero cold water mode is performed based on the outlet water temperature of the water heater.

[0053] like Figure 3 As shown, if the water heater reaches the preset start time, the preheating operation of the zero cold water mode (ie, zero cold water preheating) can be performed. If the water heater does not reach the preset start time, it is necessary to re-determine whether there is historical operation data within 1 week (ie, within the preset time period).

[0054] After turning on the zero cold water preheating, the user can start using water. In this embodiment, it is not limited to taking the operation data of the water heater that is not in the zero cold water mode and whose operation time belongs to the preset self-learning period as the historical operation data. That is, in this embodiment, the operation data of the water heater that is in the zero cold water mode and meets certain conditions can also be taken as the historical operation data.

[0055] In some embodiments, the start time and the end time of water use of the water heater are determined; if the start time and the end time of water use both belong to the self-learning period, the operation data of the water heater is obtained as the historical operation data.

[0056] During the operation of the water heater in the zero cold water mode, the present embodiment can obtain the above historical operation data according to some specified conditions. For example, if the operation time of the water heater belongs to the preset self-learning period, the operation data of the water heater is obtained as the historical operation data.

[0057] like Figure 3As shown, if the water use start time and the water use end time both belong to the self-learning period, it is considered that the current running time of the water heater in the zero cold water mode belongs to the preset self-learning period. This embodiment can use the running data of the water heater in the zero cold water mode and whose running time belongs to the preset self-learning period as historical running data.

[0058] In summary, in this embodiment, no matter whether the water heater is in the zero cold water mode or not, as long as the running time of the water heater belongs to the preset self-learning period, the running data of the water heater can be obtained as the historical running data. That is, the running data of the water heater is determined as the historical running data, which needs to meet one condition: the running time of the water heater belongs to the preset self-learning period.

[0059] Among them, the self-learning period can be added by the user, and the self-learning time period of each self-learning period can be set by the user, which has a high degree of freedom. For example, the user can set the self-learning period to 9:00-10:00 pm and 7:00-8:00 am, and the period can be set to the past week or two weeks, or use the data of any period in the past for learning, and independently cut invalid data, etc. If the user is out and detects that the water heater has not been used for a period of time, the user is prompted whether to pause it.

[0060] The above method provided by the embodiment of the present invention can set a self-learning period and use the operating data of the water heater whose operating time belongs to the preset self-learning period as historical operating data, thereby enhancing the self-learning effect of the zero cold water mode of the water heater for users with irregular water use habits, thereby improving the user experience.

[0061] In the above method provided by the embodiment of the present invention, the learning period can be added by the user independently, and the self-learning time period of each self-learning period can be set by the user independently, which has a high degree of freedom.
