[0039] First, the terms used in this invention will be explained:
[0040] 1) Smart home appliances refer to home appliances formed by introducing microprocessor, sensor technology and network communication technology into home appliances.

[0041] 2) Terminal devices refer to electronic devices with wireless connectivity.

[0044] The principle of the instant water heater involved in the embodiments of the present invention will be briefly introduced below:
[0045] Figure 1 This is a schematic diagram of the structure of a fast-heating water heater provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the instantaneous water heater 1 includes an inner tank 11 for storing water. The inner tank 11 has an inlet pipe 12 and an outlet pipe 13. One end of the inlet pipe 12 is connected to a cold water pipe outside the instantaneous water heater, and the other end is an inlet 121, communicating with the inside of the inner tank 11, for inputting cold water into the inner tank 11. One end of the outlet pipe 13 is connected to an external water outlet pipe of the instantaneous water heater, and the other end is an outlet 131, communicating with the inside of the inner tank 11, for delivering hot water to the point of use. The inner tank 11 is equipped with a full-tank heating unit 14 for conventional heating and a dynamic heating unit 15 that can be dynamically activated and dynamically heated. For example, the full-tank heating unit 14 can be distributed throughout the inner tank 11 to achieve conventional and even heating of the water stored in the tank 11. The dynamic heating unit 15 is located at the outlet pipe 13, more specifically, for example, near the outlet 131. When the dynamic heating unit 15 is activated, it heats the water flowing into the outlet pipe 13 through the outlet 131, causing the hot water temperature output through the outlet pipe 13 to rise rapidly. For example, the full-tank heating unit 14 and the dynamic heating unit 15 are, for instance, electric heating elements. A flow sensor 16 is installed inside the inlet pipe 12 to detect the water flow rate entering the inner tank through the inlet pipe 12.
[0046] like Figure 1 The instant water heater shown preheats the water in the inner tank through a full-tank heating unit, keeping the water temperature within a certain range. When there is a demand for water, the dynamic heating unit heats the hot water output through the outlet pipe, further increasing the outlet water temperature to meet the user's water needs. At the same time, it avoids the energy waste caused by heating the water stored in the entire inner tank.
[0047] However, in actual use, instant water heaters in homes typically need to supply water to multiple points of use, and the water temperature requirements of each point are often different. For example, at the kitchen water point, the user needs hot water for washing vegetables, requiring a temperature of 20 degrees Celsius; at the bathroom water point, the user needs hot water for bathing, requiring a temperature of 40 degrees Celsius. In this scenario, for the kitchen water point, even if the dynamic heating unit is not turned on, it can meet the user's water temperature requirements. Turning on the dynamic heating unit, on the other hand, would cause the user discomfort due to excessively high temperatures. For the bathroom water point, the dynamic heating unit must be turned on to meet the user's water temperature requirements. In existing technology, the condition for instant water heaters to trigger the dynamic heating unit is a fixed flow threshold, such as 0. That is, as long as water is detected flowing out of the inner tank, it is considered that the user needs hot water, and the dynamic heating unit is then turned on to heat the water output by the water heater. This leads to problems such as uncomfortable water use at different points of use (such as the kitchen water point in the above example) and energy waste.
[0048] Therefore, there is an urgent need for a water heater control method based on dynamic water flow thresholds to solve the problems of insufficient water supply and energy waste caused by using fixed flow thresholds as the trigger for dynamic heating unit activation in existing technologies.
[0049] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present invention will now be described with reference to the accompanying drawings.
[0050] Figure 2 A flowchart of a water heater control method provided in one embodiment of the present invention, applied to, for example... Figure 1 The instant water heater shown is, for example Figure 2 As shown, the water heater control method provided in this embodiment includes the following steps:
[0051] Step S101: Obtain configuration information and determine the dynamic water flow threshold based on the configuration information.
[0052] For example, configuration information refers to parameters used to determine the dynamic water flow threshold. There are multiple ways to obtain configuration information. In one possible approach, the instantaneous water heater receives and parses a configuration file or configuration parameters input by the user through an application (APP) to obtain the configuration information. The configuration file or configuration parameters may include specific numerical values representing the dynamic water flow threshold; alternatively, they may include an identifier representing the dynamic water flow threshold. After parsing the configuration file or configuration parameters, the controller of the instantaneous water heater obtains the identifier representing the dynamic water flow threshold and determines the specific data corresponding to that identifier based on a preset mapping table, thereby determining the dynamic water flow threshold.
[0053] In another possible implementation, the configuration information includes a strategy for determining the dynamic water flow threshold. The instantaneous water heater determines the dynamic water flow threshold based on this strategy. More specifically, the strategy for determining the dynamic water flow threshold could be, for example, determining the corresponding dynamic water flow threshold based on the current time, so that the dynamic water flow threshold can meet the user's water demand in different seasons and at different times of day. Another example is determining the corresponding dynamic water flow threshold based on a user identifier, so that the dynamic water flow threshold can meet the personalized needs of different users. The configuration information may include a strategy identifier. The instantaneous water heater determines a specific target strategy based on a preset specific strategy dataset and the strategy identifier in the configuration information, and determines the dynamic water flow threshold based on this target strategy. The strategy identifier in the configuration information can be carried in a configuration file or configuration parameters input by the user through an app. The controller of the instantaneous water heater obtains the strategy identifier in the configuration information by parsing this configuration file or configuration parameters.
[0054] Step S102: Detect the water flow rate of the inner tank. The water flow rate of the inner tank represents the current flow rate of water flowing out of the inner tank.
[0055] In one possible implementation, refer to Figure 1 As shown, a flow sensor is installed in the inlet or outlet pipe of the inner tank to measure the water flow rate. This flow sensor detects the current flow rate of water leaving the inner tank, i.e., the inner tank water flow rate. The inner tank water flow rate determines the current water output of the instant water heater, i.e., its usage. More specifically, if there is a mapping relationship between the inner tank water flow rate and the user's specific needs—for example, when the user washes their hands at water point a, the inner tank water flow rate is A; when the user showers at water point b, the inner tank water flow rate is B—then the inner tank water flow rate reflects the user's current water demand.
[0056] In another possible implementation, the instant water heater directly or indirectly receives water flow information collected by other sensors through a built-in communication unit, thereby determining the water flow in the inner tank. These other sensors include, for example, flow sensors installed in the hot water pipes at the point of use, flow sensors on smart water valves, etc., which will not be described in detail here.
[0057] Step S103: If the water flow rate of the inner tank matches the dynamic water flow rate threshold, then the dynamic heating unit is activated to heat the water flowing out of the inner tank.
[0058] For example, after determining the inner tank water flow rate and the dynamic water flow rate threshold, the numerical relationship between the inner tank water flow rate and the dynamic water flow rate threshold is used as a condition for matching the inner tank water flow rate with the dynamic water flow rate threshold. If this condition is met, the dynamic heating unit is triggered to start. Specifically, for example, the dynamic water flow rate threshold includes a first flow rate threshold and a second flow rate threshold, where the first flow rate threshold is less than the second flow rate threshold. The first and second flow rate thresholds constitute a flow rate threshold range. If the inner tank water flow rate is within the flow rate threshold range, the dynamic heating unit is controlled to heat. Since the dynamic water flow rate threshold is determined based on configuration information to trigger the dynamic heating unit, the flow rate threshold range corresponding to the dynamic water flow rate threshold can characterize the user's actual water usage needs.
[0059] More specifically, for example, the dynamic water flow threshold is determined based on configuration information to include a first flow threshold A and a second flow threshold B, that is, the dynamic water flow threshold includes a specific flow threshold interval [A, B]; when a user washes vegetables at water point a, the water flow rate in the inner tank is C1; when a user washes hands at water point b, the water flow rate in the inner tank is C2; when a user showers at water point c, the water flow rate in the inner tank is C3, where... Figure 3 This is a schematic diagram illustrating the numerical relationship between different inner tank water flow rates and flow threshold ranges in this embodiment, as shown below. Figure 3 As shown, the water flow rate in the inner tank is C1 when the user washes vegetables at water point a, and C2 when the user washes hands at water point b. Both are outside the flow rate threshold range [A, B]. However, the water flow rate is C3 when the user showers at water point c, which is within the flow rate threshold range [A, B]. Therefore, when the user showers at water point c, the instant water heater will trigger the dynamic heating unit to start heating, meeting the user's demand for high-temperature hot water. Conversely, when the user washes vegetables at water point a or washes hands at water point b, the instant water heater will not trigger the heating unit to start heating, but will only output water preheated by the full-tank heating unit, meeting the user's demand for low-temperature hot water. This achieves precise matching of the user's water demand, improves user comfort, and reduces energy waste caused by mismatched water demand.
[0060] In this embodiment, configuration information is acquired, and a dynamic water flow threshold is determined based on this information. The inner tank water flow rate is detected, representing the current outflow of water from the inner tank. The dynamic heating unit is then controlled to start based on the relationship between the inner tank water flow rate and the dynamic water flow threshold. Since the water flow threshold that triggers the start of the dynamic heating unit in the instant water heater is determined based on the configuration information, controlling the start of the dynamic heating unit according to the dynamic water flow threshold and the detected inner tank water flow rate allows for a more precise determination of the start-up timing. This improves the control accuracy of the dynamic heating unit, reduces energy waste, and enhances user comfort.
[0061] Figure 4 A flowchart of a water heater control method provided in another embodiment of the present invention is shown below. Figure 4 As shown, the water heater control method provided in this embodiment is... Figure 2 Based on the water heater control method provided in the illustrated embodiment, steps S101 and S103 are further refined. Therefore, the water heater control method provided in this embodiment includes the following steps:
[0062] Step S201: Obtain configuration information, which includes first mapping information and corresponding second mapping information. The first mapping information represents the mapping relationship between system time and dynamic water flow threshold, and the second mapping information is used to represent the reference information corresponding to the dynamic water flow threshold.
[0063] Step S202: Obtain the current system time, and determine the dynamic water flow threshold based on the current system time and the first mapping information. The dynamic water flow threshold includes the flow threshold range.
[0064] For example, the first mapping information represents the mapping relationship between system time and dynamic water flow threshold. Based on the first mapping information, the dynamic water flow threshold corresponding to different system times can be determined. Specifically, for example, if the system time indicates that it is currently summer, users usually require a lower water temperature, while the water heater's outlet temperature is higher. Users typically mix in cold water to lower the outlet temperature, resulting in a lower water flow rate at the water heater's outlet (i.e., the inner tank flow rate). Therefore, the dynamic water flow threshold used to match the inner tank flow rate should also be set to a lower value. Conversely, if the system time indicates that it is currently winter, users usually require a higher water temperature, and correspondingly, the dynamic water flow threshold should be set to a higher value. It should be noted that, due to regional climate differences, the first mapping information has a certain regional applicability. Users can set or adjust the first mapping information according to the specific conditions of their region; this will not be described in detail here.
[0065] Step S203: Determine the heating power corresponding to the flow threshold range.
[0066] Furthermore, exemplarily, the configuration information also includes second mapping information corresponding to the first mapping information. The second mapping information characterizes other reference information for controlling the instantaneous water heater corresponding to the dynamic water flow threshold, such as one or more sets of water temperature threshold range, heating power, and duration threshold. Specifically, the heating power is used to limit the heating function of the dynamic heating unit of the instantaneous water heater when the inner tank flow is within the flow threshold range after the flow threshold range has been determined. This achieves matching between the outlet water temperature of the instantaneous water heater and the flow threshold range. Since the flow threshold range is one implementation of the dynamic water flow threshold, and the dynamic water flow threshold corresponds to the user's water usage needs. Therefore, by setting the heating power corresponding to the dynamic water flow threshold, refined control of the dynamic heating unit can be achieved. For example, the dynamic water flow threshold includes a flow threshold range A and a flow threshold range B. According to the second mapping information, the heating power corresponding to the flow threshold range A is determined to be P1, and the heating power corresponding to the flow threshold range B is determined to be P2. When the user dispenses water at point a, the inner tank flow rate is within the flow threshold range A. At this time, the instant water heater starts the dynamic heating unit and controls the dynamic heating unit to heat at P1. When the user dispenses water at point b, the inner tank flow rate is within the flow threshold range B. At this time, the instant water heater starts the dynamic heating unit and controls the dynamic heating unit to heat at P2. Thus, different water outlet temperatures are achieved at points a and b.
[0067] Step S204: Detect the water flow rate of the inner tank. The water flow rate of the inner tank represents the current flow rate of water flowing out of the inner tank.
[0068] Step S205: Obtain the water temperature inside the tank and determine that the water heater is in dynamic heating state based on the water temperature inside the tank.
[0069] For example, when the inner tank flow rate is within the flow threshold range and the inner tank water temperature is within the preset water temperature threshold range, the water heater is in dynamic heating mode. Here, the inner tank water temperature is the temperature of the water stored in the inner tank preheated by the full-tank heating unit. The water temperature threshold range can be determined by the second mapping information, and this water temperature threshold range is lower than the water heater's set temperature. The water heater's set temperature can be considered as the user's set water demand temperature. When the inner tank water temperature is within the water temperature threshold range, it indicates that the inner tank water temperature is lower than the user's required water demand temperature; that is, the water temperature preheated only by the full-tank heating unit is insufficient to meet the user's water temperature requirements. In this case, the dynamic heating unit needs to be activated to heat the water.
[0070] Step S206: Obtain the duration of the water heater being in dynamic heating mode.
[0071] Step S207: If the duration of the water heater in dynamic heating state is longer than the preset duration threshold, then control the dynamic heating unit to heat with the heating power corresponding to the flow threshold range.
[0072] For example, because there is a pipeline for transporting hot water between the instant water heater and the point of use, even after the dynamic heating unit of the instant water heater is activated, the outlet cannot immediately output hot water at the required temperature. Therefore, if the user's water usage time at the point of use is too short, even if the dynamic heating unit is activated, the user will not be able to use hot water before the water usage ends. To further improve energy efficiency and reduce energy consumption, by obtaining the duration of the water heater in dynamic heating mode, when the heating duration exceeds a preset time threshold, it indicates that the user is in a non-temporary stable water usage state. At this time, controlling the dynamic heating unit to heat at the heating power corresponding to the threshold range can avoid energy waste caused by the user's short-term temporary water usage.
[0073] The duration threshold can be determined using the second mapping information.
[0074] Figure 5 This is a schematic diagram of the process of starting a dynamic heating unit according to an embodiment of the present invention, as shown below. Figure 5 As shown, after obtaining the configuration information, a dynamic water flow threshold is determined based on the system time. This dynamic water flow threshold includes multiple flow threshold ranges, each corresponding to three reference parameters: a water temperature threshold range, heating power, and a duration threshold. Then, based on the collected inner tank flow rate, a target flow threshold range is determined from these ranges, along with the corresponding water temperature threshold range, heating power, and duration threshold. Next, the inner tank water temperature is collected. Based on this water temperature, the water temperature threshold range, and the duration threshold, the triggering timing of the dynamic heating unit is determined, and the dynamic heating unit is activated, heating at the power corresponding to the threshold range.
[0075] Figure 6 This is a schematic diagram of a water heater control device provided in one embodiment of the present invention, applied to an instant water heater, such as... Figure 6 As shown, the water heater control device 3 provided in this embodiment includes:
[0076] The acquisition module 31 is used to acquire configuration information and determine the dynamic water flow threshold based on the configuration information.
[0077] The detection module 32 is used to detect the water flow rate of the inner tank, which represents the current water flow rate out of the inner tank.
[0078] If the water flow rate in the inner tank matches the dynamic water flow rate threshold, the control module 33 activates the dynamic heating unit to heat the water flowing out of the inner tank.
[0079] In one possible implementation, the dynamic water flow threshold includes a flow threshold range; the control unit is specifically configured to: activate the dynamic heating unit if the inner tank flow rate is within the flow threshold range.
[0080] In one possible implementation, the detection module 32 is further configured to: acquire the inner tank water temperature; when the control module 33 determines that the dynamic heating unit will be activated if the inner tank flow rate is within the flow threshold range, it is specifically configured to: control the dynamic heating unit to heat if the inner tank flow rate is within the flow threshold range and the inner tank water temperature is within the preset water temperature threshold range.
