Among them, the client 2 communicates with the server 3 and the hot water equipment 1 through a network. The server 3 communicates with the hot water equipment 1 through a network.

[0029] Optionally, the hot water equipment 1 includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the hot water equipment water intake control method of the present application is implemented. The specific steps are as follows: obtain a water intake instruction, and the water intake instruction carries a water intake temperature; respond to the water intake instruction and obtain the water inlet temperature of the water inlet; determine a control strategy according to the water intake temperature and the water inlet temperature; and control the hot water equipment 1 to take water according to the control strategy.

[0033] It can be understood that in this application, the normal temperature unit, the heat exchange unit, and the instant heating unit provided in the hot water device cooperate with each other, and there is no need to store hot water in advance, thereby avoiding the growth of microorganisms and chemical changes in water quality caused by long-term storage of hot water, and ensuring the freshness of the hot water. At the same time, the cooperation between the heat exchange unit and the instant heating unit can be adjusted instantaneously according to actual needs. Under different water intake temperatures and water inlet temperatures, according to the determined control strategy, it can ensure that the water flow rate of the hot water is stable in various situations, effectively solving the problem of unstable water intake speed. Moreover, this method of determining the control strategy based on the water intake temperature and the water inlet temperature enables the most suitable strategy to be adopted for different temperature situations, ensuring that the water intake control achieves the optimal effect.

[0034] As Figure 3 shown, the hot water device 1 is provided with a normal temperature unit 110, a heat exchange unit 120, and an instant heating unit 130. The water inlet end of the normal temperature unit 110 and the water inlet end of the heat exchange unit 120 are both connected to the water inlet 140. The water outlet end of the normal temperature unit 110 and the water outlet end of the heat exchange unit 120 are both connected to the water inlet end of the instant heating unit 130.

[0035] It can be understood that pure water and / or tap water is input into the normal temperature unit 110 and / or the heat exchange unit 120 through the water inlet 140.

[0036] As Figure 4As shown, the hot water device 1 is further provided with a water purification unit and a wastewater unit; the water purification unit includes: a pre-filter 41, a water inlet valve 42, a first water pump 43, an RO filter 44, a post-filter 45, a reflux valve 46 and a first check valve 47. The pre-filter 41, the water inlet valve 42, the first water pump 43, the water inlet end of the RO filter 44, the purified water end of the RO filter 44 and the post-filter 45 are connected in series. The water outlet end of the post-filter 45 is connected to one end of the reflux valve 46. The water outlet end of the post-filter 45 serves as the water inlet. The water inlet end of the first check valve 47 is connected to the other end of the reflux valve 46. The water inlet end of the pre-filter 41 is connected to the water outlet end of the first check valve 47 and the water source. The wastewater end of the RO filter 44 and the pressure relief end of the heat exchange unit are both connected to the wastewater unit.

[0037] Optionally, the pre-filter 41 is a filter for primary filtration. For example, a filter using PP cotton is adopted.

[0038] The RO filter 41, whose full name is Reverse Osmosis filter, is a key component widely used in the field of water treatment and purification.

[0039] Optionally, the post-filter 45 adopts activated carbon to remove the odor in the water.

[0040] It can be understood that the section from the water inlet 140, the first three-way valve 11, the normal temperature water pipe 12 to the first end of the control valve 31 is taken as the normal temperature unit 110. The section from the water inlet 140, the heat exchanger 21, the second check valve 27 to the first end of the control valve 31, and the water inlet 140, the first two-way valve 24, the third check valve 23, the heat exchange water tank 22, the second water pump 25 and the fourth check valve 29 are taken as the heat exchange unit 120. The control valve 31, the faucet heater 32 and the water intake 33 are taken as the instant heating unit 130. The second two-way valve 51 and the wastewater pipe 52 are taken as the wastewater unit.

[0041] It can be understood that the instant heating unit 130 can be assembled into a faucet with a heating function.

[0042] The first two-way valve 24, the second two-way valve 51, the reflux valve 46 and the water inlet valve 42 all adopt two-way valves.

[0043] The first three-way valve 11 and the control valve 31 both adopt three-way valves.

[0044] The first check valve 47, the second check valve 27, the third check valve 23 and the fourth check valve 29 all adopt check valves.

[0045] The first water pump 43 and the second water pump 25 both adopt water pumps.

[0046] The heat exchange water tank 22 is a heat storage tank with a heating function.

[0047] The faucet heater 32 uses a component having a heating function.

[0048] The waste water pipe 52 and the normal temperature water pipe 12 are both water pipes.

[0049] The principle of heat exchange is as follows: the hot water in the water exchange tank 22 (it can also be other media that can store thermal energy, such as heat storage oil) is pumped into the first heat exchange pipe of the heat exchanger 21 through the second water pump 25, and the hot water in the first heat exchange pipe exchanges heat with the second heat exchange pipe of the heat exchanger 21, so that the water in the first heat exchange pipe becomes cold and the water in the second heat exchange pipe becomes warmer. The cooled water in the first heat exchange pipe returns to the water exchange tank 22 through the pipe, wherein the water input from the water inlet 140 passes through the first three-way valve 11, the second heat exchange pipe, and the second one-way valve 27.

[0050] The water path corresponding to the water inlet 140 , the first two-way valve 24 , the third one-way valve 23 to the hot water exchange tank 22 is used as the water replenishment water path of the hot water exchange tank 22 .

[0051] The water path from the heat exchange water tank 22, the fourth one-way valve 29 to the waste water pipe 52 is used as the waste water path and / or the pressure relief gas path of the heat exchange water tank 22. Thus, the water in the heat exchange unit 120 is replaced to avoid the breeding of bacteria during long-term storage.

[0052] Optionally, a first temperature sensor 48 may be provided in the water heater 1, and the data detected by the first temperature sensor 48 may be used as the water inlet temperature of the water inlet 140. The first temperature sensor may be installed in the water path downstream of the water inlet 140, or may be installed in the water path upstream of the water inlet 140 (for example, Figure 5 and Figure 6 ).

[0053] Optionally, a water quality sensor 49 may be provided in the hot water device 1. The water quality sensor 49 is used to detect the water quality (referred to as purified water quality) output by the post-filter element 45. If the purified water quality is outside the preset water quality range, it means that the water purification unit needs to be cleaned or the filter element needs to be replaced.

[0054] Optionally, a second temperature sensor 28 may be provided in the water heater 1 , and the second temperature sensor 28 is used to detect the temperature of water output from the heat exchanger 21 to the instant heating unit 130 .

[0055] Optionally, a third temperature sensor 26 may be provided in the water heater 1 . The second temperature sensor 26 is used to detect the temperature of water output from the water exchange tank 22 to the heat exchanger 21 .

[0056] It can be understood that the processor of the hot water device 1 is electrically connected to each electrically controlled component in the hot water device 1 (such as, the hot water exchange tank 22, the first water pump 43, the second water pump 25, the first three-way valve 11, the control valve 31, the first two-way valve 24, the second two-way valve 51, the return valve 46, the water inlet valve 42, the hot water exchange tank 22 and the faucet heater 32, etc.).

[0057] Among them, the client 2 can be but is not limited to various personal computers, laptop computers, smart phones, tablet computers and portable wearable devices. The server 3 can be implemented by an independent server or a server cluster composed of multiple servers.

[0058] The present invention will be described in detail below through specific embodiments.

[0059] Please refer to Figure 2 as shown in Figure 2 FIG. 13 is a schematic flowchart of a hot water device water intake control method provided by an embodiment of the present invention. The method is used for a hot water device, and a normal temperature unit, a heat exchange unit and an instant heating unit are provided in the hot water device. The water inlet ends of the normal temperature unit and the heat exchange unit are both connected to the water inlet, and the water outlet ends of the normal temperature unit and the heat exchange unit are both connected to the water inlet end of the instant heating unit;

[0060] The method includes:

[0061] S1: Obtain a water intake instruction, and the water intake instruction carries a water intake temperature;

[0062] The water intake instruction is an instruction for the hot water device to respond to the water intake demand.

[0063] Optionally, on the interface of the client 2 (such as a mobile APP or the control end of other intelligent devices), there will be a special water intake function section. A temperature adjustment slider or a digital input box is provided in the section. The user can directly drag the slider or enter a specific number (such as 30°C, 45°C, 80°C, etc.) to specify the water intake temperature, and then click the "Water Intake" button. At this time, the client will send the water intake instruction including the water intake temperature to the execution device that implements the hot water device water intake control method of the present application.

[0064] Optionally, the client 2 may pre-set some common water intake temperature modes, such as "warm water (40°C)", "making tea (80°C)", "making coffee (90°C)", etc. The user only needs to select the corresponding mode on the client, and the client will include the corresponding water intake temperature in the water intake instruction and send it to the execution device that implements the hot water device water intake control method of the present application.

[0065] Optionally, temperature adjustment buttons are provided on the control panel of the hot water device 1. For example, there are "+" and "-" buttons. The user can press the "+" button to increase the temperature value and the "-" button to decrease the temperature value until the desired water intake temperature is displayed, and then press the "Water Intake" button. In this way, the hot water device receives a water intake instruction containing the water intake temperature.

[0066] Optionally, if the hot water device 1 is equipped with a touch screen, its operation interface is similar to that of the client 2. There will be a temperature adjustment area on the touch screen. The user can directly input or select the water intake temperature on the screen and then trigger the sending of the water intake instruction on the touch screen.

[0067] S2: In response to the water intake instruction, obtain the water inlet temperature of the water inlet;

[0068] Specifically, when the water intake instruction is obtained, obtain the temperature detected in real time by the first temperature sensor 48, and use this temperature as the water inlet temperature of the water inlet.

[0069] S3: Determine a control strategy according to the water intake temperature and the water inlet temperature;

[0070] The control strategy describes the control data of each electronic control component in the hot water device.

[0071] The control strategy at least includes: normal temperature parameters, heat exchange parameters, and instant heating parameters. The control strategy may also include: instant heating control data and / or heat exchange control data. The instant heating control data is the data used to describe the speed at which the heat exchange water tank 22 conveys water to the heat exchanger 21. The instant heating control data is the data used to describe the heating power of the faucet heater 32.

[0072] The value of the normal temperature parameter is a conduction identifier (that is, the normal temperature unit is conducting) or a closing identifier (that is, the normal temperature unit is closed). The value of the heat exchange parameter is a conduction identifier (that is, the heat exchange unit is conducting) or a closing identifier (that is, the heat exchange unit is closed). The value of the instant heating parameter is a non-heating identifier (that is, the faucet heater 32 does not need to be heated) and a heating identifier (that is, the faucet heater 32 needs to be heated).

[0073] Optionally, a look-up table method is used to determine the control strategy according to the water intake temperature and the water inlet temperature.

[0074] Optionally, input the water intake temperature and the water inlet temperature into a pre-trained strategy prediction model for classification prediction, and use the classification category (that is, the strategy identifier) corresponding to the vector element with the largest value in the vector obtained by the classification prediction as the target strategy identifier, and use the control data corresponding to the target strategy identifier as the control strategy.

[0075] Optionally, based on a preset policy determination logic, a look-up table method is used according to the water intake temperature and the inlet water temperature to determine the control policy.

[0076] The pre-trained policy prediction model is a pre-trained classification model. The model structure and model training method of the policy prediction model can be selected from the prior art and will not be elaborated here.

[0077] S4: Control the water intake of the hot water device according to the control policy.

[0078] Specifically, according to the control policy, control some or all of the normal temperature unit, heat exchange unit and instant heating unit of the hot water device to work, so that the hot water device outputs water with a temperature of the water intake temperature.

[0079] It can be understood that the cooperation of the hot water device and the hot water device water intake control method in this application enables the hot water device to output hot water with a large flow rate and a stable water intake speed. For example, in daily life, the hot water device outputs water at 1.5 L / min.

[0080] Optionally, the hot water device adopts a fixed water intake speed. At this time, steps S3 and S4 do not need to involve the water intake speed.

[0081] Optionally, when the hot water device adopts a flexible water intake speed, the steps of determining the control policy according to the water intake temperature and the inlet water temperature and controlling the water intake of the hot water device according to the control policy include: determining the control policy according to the water intake speed, the water intake temperature and the inlet water temperature, and controlling the hot water device to take water at the water intake speed according to the control policy. Optionally, a look-up table method is used according to the water intake speed, the water intake temperature and the inlet water temperature to determine the control policy. Optionally, input the water intake speed, the water intake temperature and the inlet water temperature into the pre-trained policy prediction model for classification prediction, and use the classification category corresponding to the vector element with the largest value in the vector obtained by the classification prediction (that is, the policy identifier) as the target policy identifier, and use the control data corresponding to the target policy identifier as the control policy.

[0082] In this embodiment, the normal-temperature unit, heat exchange unit, and instant heating unit provided in the hot water device cooperate with each other, eliminating the need to store hot water in advance. This avoids the growth of microorganisms and chemical changes in water quality caused by long-term hot water storage, ensuring the freshness of the hot water. At the same time, the heat exchange unit and the instant heating unit cooperate to enable instant adjustment according to actual needs. At different water intake temperatures and inlet water temperatures, based on the determined control strategy, the flow rate of the hot water can be ensured to be stable in various situations, effectively solving the problem of unstable water intake speed. Moreover, this method of determining the control strategy based on the water intake temperature and the inlet water temperature enables the adoption of the most suitable strategy for different temperature situations, ensuring that the water intake control achieves the optimal effect.

[0083] In one embodiment, the step of determining the control strategy according to the water intake temperature and the inlet water temperature includes:

[0084] S31: If the inlet water temperature is within the first range, determine the control strategy according to the water intake temperature, the inlet water temperature, and a preset first data set;

[0085] The preset first data set is a set of multiple preset temperature ranges.

[0086] Specifically, if the inlet water temperature is within the first range, compare and analyze the water intake temperature with each temperature range in the preset first data set, and then determine the control strategy based on the results of the comparison and analysis, the water intake temperature, and the inlet water temperature.

[0087] S32: If the inlet water temperature is within the second range, determine the control strategy according to the water intake temperature, the inlet water temperature, and a preset second data set.

[0088] The preset second data set is a set of multiple preset temperature ranges.

[0089] Specifically, if the inlet water temperature is within the second range, compare and analyze the water intake temperature with each temperature range in the preset second data set, and then determine the control strategy based on the results of the comparison and analysis, the water intake temperature, and the inlet water temperature.

[0090] It can be understood that steps S31 and S32 implement the determination of the control strategy using a look-up table method based on the preset strategy determination logic according to the water intake temperature and the inlet water temperature.

[0091] Optionally, the first range is greater than or equal to 25°C, and the second range is less than 25°C. It can be understood that the first range and the second range can also be set in other ways, for example, the first range is greater than or equal to 20°C, and the second range is less than 20°C. Specific limitations are not provided here.

[0092] Optionally, the first range is greater than or equal to 25 °C, and the second range is greater than 5 °C and less than 25 °C.

[0093] In this embodiment, different data sets (a set of multiple preset temperature ranges) are used to determine the control strategy when the inlet water temperature is in different temperature ranges. When the inlet water temperature is in a lower range (for example, the second range), such as close to the freezing point temperature range, the control strategy is determined through the corresponding second data set, and the heating power of the instant heating unit can be increased or the heat exchange parameters of the heat exchange unit can be adjusted to ensure that the water can be quickly heated to the target water intake temperature and a stable water intake speed can be maintained under such cold inlet water temperatures. When the inlet water temperature is in a moderate range (for example, the first range), the control strategy determined by the matching first data set can reasonably allocate the working modes of the normal temperature unit, the heat exchange unit, and the instant heating unit, avoid excessive energy consumption, and achieve high energy efficiency while ensuring fresh hot water and a stable water intake speed.

[0094] In one embodiment, the first data set is provided with a third range, a fourth range, a fifth range, and a sixth range in ascending order of temperature;

[0095] The step of determining the control strategy according to the water intake temperature, the inlet water temperature, and the preset first data set includes:

[0096] S311: If the water intake temperature is within the third range, set the normal temperature parameter to the conduction identifier, the heat exchange parameter to the off identifier, and the instant heating parameter to the non-heating identifier to obtain the control strategy;

[0097] Specifically, if the water intake temperature is within the third range, this means that the user wants normal temperature water and no heating is required. Therefore, set the normal temperature parameter to the conduction identifier, the heat exchange parameter to the off identifier, and the instant heating parameter to the non-heating identifier, and use the set normal temperature parameter, heat exchange parameter, and instant heating parameter as the control strategy. That is to say, at this time, the normal temperature unit directly outputs water to the instant heating unit, the instant heating unit does not heat the water, and the instant heating unit directly discharges the water from the hot water device, thus realizing the direct output of normal temperature water through the normal temperature water path.

[0098] S312: If the water intake temperature is within the fourth range, set the normal temperature parameter to the conduction identifier, the heat exchange parameter to the off identifier, and the instant heating parameter to the heating identifier, and determine the instant heating control data according to the water intake temperature and the inlet water temperature to obtain the control strategy;

[0099] Specifically, if the water intake temperature is within the fourth range, it means that the user wants warm water with a relatively low temperature and heating is required. Therefore, the normal temperature parameter is set as the conduction identifier, the heat exchange parameter is set as the off identifier, and the instant heating parameter is set as the heating identifier. According to the water intake temperature and the inlet water temperature, the instant heating control data is determined by using the look-up table method. The set instant heating control data, normal temperature parameter, heat exchange parameter, and instant heating parameter are used as the control strategy. That is to say, at this time, the normal temperature unit directly outputs water to the instant heating unit. Based on the instant heating control data, the instant heating unit heats the water, and the instant heating unit discharges the heated water from the hot water device, thus realizing the coordinated output of warm water with a relatively low temperature by the instant heating of the normal temperature unit and the instant heating unit.

[0100] S313: If the water intake temperature is within the fifth range, then set the normal temperature parameter as the off identifier, the heat exchange parameter as the conduction identifier, and the instant heating parameter as the non-heating identifier. Moreover, according to the water intake temperature and the inlet water temperature, determine the heat exchange control data to obtain the control strategy;

[0101] Specifically, if the water intake temperature is within the fifth range, it means that the user wants warm water with a medium temperature and heating is required. Therefore, set the normal temperature parameter as the off identifier, the heat exchange parameter as the conduction identifier, and the instant heating parameter as the non-heating identifier. According to the water intake temperature and the inlet water temperature, determine the heat exchange control data by using the look-up table method. The set heat exchange control data, normal temperature parameter, heat exchange parameter, and instant heating parameter are used as the control strategy. That is to say, at this time, based on the heat exchange control data, the heat exchange unit heats the water input into the heat exchange unit through the water inlet. The heated water is output to the instant heating unit, and the instant heating unit does not heat the water. The instant heating unit directly discharges the water from the hot water device, thus realizing the coordinated output of warm water with a medium temperature by the heat exchange heating of the heat exchange unit and the non-heating direct discharge of the instant heating unit.

[0102] S314: If the water intake temperature is within the sixth range, then set the normal temperature parameter as the off identifier, the heat exchange parameter as the conduction identifier, and the instant heating parameter as the heating identifier. Moreover, according to the water intake temperature and the inlet water temperature, determine the instant heating control data and the heat exchange control data to obtain the control strategy.

[0103] Specifically, if the water intake temperature is within the sixth range, it means that the user wants warm or boiling water with a high temperature and heating is required. Therefore, the normal temperature parameter is set to the off flag, the heat exchange parameter is set to the on flag, and the instant heating parameter is set to the heating flag. According to the water intake temperature and the inlet water temperature, the instant heating control data and the heat exchange control data are determined by using the look-up table method. The set instant heating control data, heat exchange control data, normal temperature parameter, heat exchange parameter, and instant heating parameter are used as the control strategy. That is to say, at this time, based on the heat exchange control data, the heat exchange unit heats the water input into the heat exchange unit through the water inlet, and the heated water is output to the instant heating unit. Based on the instant heating control data, the instant heating unit performs secondary heating on the water, and the instant heating unit discharges the heated water from the hot water device, thereby realizing the heat exchange heating of the heat exchange unit and the instant heating output of the instant heating unit to provide warm or boiling water with a high temperature. The dual cooperation of the heat exchange heating of the heat exchange unit and the instant heating of the instant heating unit meets the requirements of large flow rate and stable water intake speed.

[0104] Optionally, the third range is the normal temperature range, the start value of the fourth range (the fourth range does not include this start value) is greater than or equal to the end value of the normal temperature range, the end value of the fourth range (the fourth range includes this end value) is 45 °C, the start value of the fifth range (the fifth range does not include this start value) is 45 °C, the end value of the fifth range (the fifth range does not include this end value) is 76 °C, and the sixth range is greater than or equal to 76 °C. It can be understood that the range values (that is, the start value and the end value) of the third range, the fourth range, the fifth range, and the sixth range can also adopt other temperatures, which are not specifically limited here.

[0105] Optionally, the normal temperature range is equal to the external ambient temperature.

[0106] Optionally, the start value of the normal temperature range is the external ambient temperature minus the first threshold, and the end value of the start value of the normal temperature range is the external ambient temperature plus the second threshold.

[0107] In this embodiment, the first data set is provided with a third range, a fourth range, a fifth range, and a sixth range in ascending order of temperature, thereby meeting the water intake requirements for any water intake temperature; according to the settings of the corresponding ranges in the first data set, the control strategy is dynamically adjusted to avoid overheating or insufficient heating. Whether the water intake temperature required by the user is a lower temperature (such as warm water for washing hands, etc.) or a higher temperature (such as high-temperature hot water requirements for making tea, brewing coffee, etc.), the heating process can be accurately controlled and hot water that meets the requirements can be stably provided.

[0108] In one embodiment, the second data set is provided with: a third range, a seventh range, and a sixth range in ascending order of temperature;

[0109] The step of determining the control strategy according to the water intake temperature, the inlet water temperature, and a preset second data set includes:

[0110] S321: If the water intake temperature is within the third range, set the normal temperature parameter to the on identifier, the heat exchange parameter to the off identifier, and the instant heating parameter to the non-heating identifier, so as to obtain the control strategy;

[0111] Specifically, if the water intake temperature is within the third range, this means that the user wants normal temperature water and no heating is required. Therefore, set the normal temperature parameter to the on identifier, the heat exchange parameter to the off identifier, and the instant heating parameter to the non-heating identifier, and use the set normal temperature parameter, heat exchange parameter, and instant heating parameter as the control strategy. That is to say, at this time, the normal temperature unit directly outputs water to the instant heating unit, and the instant heating unit does not heat this water and directly discharges this water from the hot water device, thus realizing the direct output of normal temperature water through the normal temperature water path.

[0112] S322: If the water intake temperature is within the seventh range, set the normal temperature parameter to the off identifier, the heat exchange parameter to the on identifier, and the instant heating parameter to the non-heating identifier, and determine heat exchange control data according to the water intake temperature and the inlet water temperature, so as to obtain the control strategy;

[0113] Specifically, if the water intake temperature is within the seventh range, this means that the user wants warm water with a medium temperature and heating is required. Therefore, set the normal temperature parameter to the off identifier, the heat exchange parameter to the on identifier, and the instant heating parameter to the non-heating identifier, and use the look-up table method to determine heat exchange control data according to the water intake temperature and the inlet water temperature. Use the set heat exchange control data, normal temperature parameter, heat exchange parameter, and instant heating parameter as the control strategy. That is to say, at this time, based on the heat exchange control data, the heat exchange unit heats the water input into the heat exchange unit through the water inlet, and the heated water is output to the instant heating unit. The instant heating unit does not heat this water and directly discharges this water from the hot water device, thus realizing the coordinated output of warm water with medium temperature by the heat exchange heating of the heat exchange unit and the non-heating direct discharge of the instant heating unit.

[0114] S323: If the water intake temperature is within the sixth range, set the normal temperature parameter to the off identifier, the heat exchange parameter to the on identifier, and the instant heating parameter to the heating identifier, and determine instant heating control data and heat exchange control data according to the water intake temperature and the inlet water temperature, so as to obtain the control strategy.

[0115] Specifically, if the water intake temperature is within the sixth range, it means that the user wants warm or boiling water with a high temperature and heating is required. Therefore, the normal temperature parameter is set to the off flag, the heat exchange parameter is set to the on flag, and the instant heating parameter is set to the heating flag. According to the water intake temperature and the inlet water temperature, the instant heating control data and the heat exchange control data are determined by using the look-up table method. The set instant heating control data, heat exchange control data, normal temperature parameter, heat exchange parameter, and instant heating parameter are used as the control strategy. That is to say, at this time, based on the heat exchange control data, the heat exchange unit heats the water input into the heat exchange unit through the water inlet, and the heated water is output to the instant heating unit. Based on the instant heating control data, the instant heating unit reheats the water, and the instant heating unit discharges the heated water from the hot water device, thereby realizing the heat exchange heating of the heat exchange unit and the instant heating output of the instant heating unit to provide warm or boiling water with a high temperature. The dual cooperation of the heat exchange heating of the heat exchange unit and the instant heating of the instant heating unit meets the requirements of large flow rate and stable water intake speed.

[0116] Optionally, the third range is the normal temperature range, the start value of the fourth range (the fourth range does not include this start value) is greater than or equal to the end value of the normal temperature range, the end value of the fourth range (the fourth range includes this end value) is 45 °C, the start value of the fifth range (the fifth range does not include this start value) is 45 °C, the end value of the fifth range (the fifth range does not include this end value) is 76 °C, the sixth range is greater than or equal to 76 °C, the start value of the seventh range (the seventh range includes this start value) is greater than or equal to the end value of the normal temperature range, and the end value of the seventh range (the seventh range does not include this end value) is 76 °C. It can be understood that the range values (that is, the start value and the end value) of the third range, the fourth range, the fifth range, and the sixth range can also adopt other temperatures, which are not specifically limited here.

[0117] In this embodiment, the second data set is provided with the third range, the seventh range, and the sixth range in ascending order of temperature, so as to meet the water intake requirements for any water intake temperature; according to the settings of the corresponding ranges in the second data set, the control strategy is dynamically adjusted to avoid overheating or insufficient heating. Whether the water intake temperature required by the user is a lower temperature (such as warm water for washing hands, etc.) or a higher temperature (such as high-temperature hot water requirements for making tea, brewing coffee, etc.), the heating process can be accurately controlled and hot water that meets the requirements can be stably provided.

[0118] In one embodiment, the step of setting the normal temperature parameter to the off flag, the heat exchange parameter to the on flag, and the instant heating parameter to the non-heating flag, and determining the heat exchange control data according to the water intake temperature and the inlet water temperature to obtain the control strategy includes:

[0119] S331: Obtain the heat exchange energy storage data of the heat exchange unit;

[0120] The heat exchange and energy storage data of the heat exchange unit is data describing the heat energy stored by the heat exchange unit.

[0121] Optionally, the heat exchange and energy storage data can be expressed by the temperature of the heat exchange medium (such as water, stored hot oil) in the heat exchange water tank 22. The temperature of the heat exchange medium in the heat exchange water tank 22 is detected in real time by installing a temperature sensor in the heat exchange water tank 22. This application obtains the temperature detected by the sensor in real time as the heat exchange and energy storage data of the heat exchange unit.

[0122] S332: Determine whether the expected output temperature of the heat exchange unit is lower than the water intake temperature according to the water intake temperature and the heat exchange and energy storage data;

[0123] Optionally, a preset regular expression is used to determine whether the expected output temperature of the heat exchange unit is lower than the water intake temperature according to the water intake temperature and the heat exchange and energy storage data.

[0124] Optionally, first, a preset heat exchange temperature calculation formula is used to determine the expected output temperature of the heat exchange unit according to the water intake temperature and the heat exchange and energy storage data, and then the expected output temperature is compared with the water intake temperature.

[0125] It can be understood that the preset heat exchange temperature calculation formula can be obtained by fitting multiple sets of historical data.

[0126] Optionally, the water intake temperature and the heat exchange and energy storage data are spliced and then input into a pre-trained temperature prediction model for classification prediction, and the classification category (that is, the temperature) corresponding to the vector element with the largest value in the vector obtained by the classification prediction is used as the expected output temperature of the heat exchange unit.

[0127] The temperature prediction model is a pre-trained classification model. The model structure and model training method of the temperature prediction model can be selected from the prior art and will not be elaborated here.

[0128] S333: If so, set the normal temperature parameter to the off flag, the heat exchange parameter to the on flag, and the instant heating parameter to the heating flag, and, determine the heat exchange control data in the control strategy according to the water intake temperature and the expected output temperature, and, determine the instant heating control data in the control strategy according to the expected output temperature and the water intake temperature, so as to obtain the control strategy;

[0129] Specifically, if the expected output temperature of the heat exchange unit is lower than the water intake temperature, which means that the heat energy stored in the heat exchange unit does not meet the heat exchange heating requirements. To quickly meet the user's water intake demand, the cooperation of the heat exchange unit and the instant heating unit is required. Therefore, the normal temperature parameter is set as the off flag, the heat exchange parameter is set as the on flag, and the instant heating parameter is set as the heating flag. Moreover, according to the inlet water temperature and the expected output temperature, the heat exchange control data in the control strategy is determined by using the look-up table method. And according to the expected output temperature and the water intake temperature, the instant heating control data in the control strategy is determined by using the look-up table method. The set instant heating control data, heat exchange control data, normal temperature parameter, heat exchange parameter, and instant heating parameter are used as the control strategy.

[0130] S334: If not, then set the normal temperature parameter as the off flag, the heat exchange parameter as the on flag, and the instant heating parameter as the non-heating flag. Moreover, according to the water intake temperature and the inlet water temperature, determine the heat exchange control data in the control strategy to obtain the control strategy.

[0131] Specifically, if not, that is, the expected output temperature of the heat exchange unit is not lower than the water intake temperature, which means that the heat energy stored in the heat exchange unit meets the heat exchange heating requirements. Only the heat exchange unit needs to perform heat exchange heating. Therefore, set the normal temperature parameter as the off flag, the heat exchange parameter as the on flag, and the instant heating parameter as the non-heating flag. Moreover, according to the water intake temperature and the inlet water temperature, determine the heat exchange control data in the control strategy to obtain the control strategy. The set heat exchange control data, normal temperature parameter, heat exchange parameter, and instant heating parameter are used as the control strategy.

[0132] In this embodiment, the expected output temperature of the heat exchange unit is lower than the water intake temperature. According to the inlet water temperature and the expected output temperature, the heat exchange control data in the control strategy is determined. And according to the expected output temperature and the water intake temperature, the instant heating control data in the control strategy is determined to quickly meet the user's water intake demand through the cooperation of the heat exchange unit and the instant heating unit, which is beneficial to improving the user experience; when the expected output temperature of the heat exchange unit is not lower than the water intake temperature, only the heat exchange unit is used for heat exchange heating, thus saving energy consumption.

[0133] In one embodiment, the step of controlling the water intake of the hot water device according to the control strategy includes:

[0134] Control the water intake of the hot water device according to the control strategy. During the water intake process, the method further includes:

[0135] S41: Obtain the actual output temperature of the heat exchange unit, and update the instant heating control data in the control strategy according to the actual output temperature and the water intake temperature.

[0136] Specifically, obtain the temperature of the water output from the heat exchanger 21 to the instant heating unit 130 detected in real time by the second temperature sensor 28, and use this temperature as the actual output temperature of the heat exchange unit; according to the actual output temperature and the water intake temperature, determine the control compensation data by using the look-up table method, and update the instant heating control data in the control strategy according to the control compensation data. Among them, the specific operation of the update can be one or more of replacement, addition, and multiplication.

[0137] In this embodiment, the instant heating control data in the control strategy is updated according to the actual output temperature of the heat exchange unit and the water intake temperature, so as to realize filling the difference in the water heat exchange temperature of the heat exchange unit by fine-tuning the instant heating control data of the instant heating unit, and finally ensure that the instant heating unit can output water with a temperature equal to the water intake temperature.
