[0064] The present application provides a method for regulating outlet water temperature, a method for determining a preset parameter group, and a water supply device, which are described in detail below.

[0065] First, the present application provides a method for regulating water outlet temperature. The executor of the method can be a water outlet temperature regulating device, or a water supply device, a water purifier, a server device, a physical host or a user equipment (UE) and other different types of equipment that integrate the water outlet temperature regulating device. The water outlet temperature regulating device can be implemented in hardware or software, and the UE can specifically be a terminal device such as a smart phone, a tablet computer, a laptop computer, a PDA or a desktop computer.

[0066] The outlet water temperature adjustment method can be applied to water supply equipment such as water supply devices, water purifiers, and pipeline water dispensers to quickly adjust the outlet water temperature of the equipment to meet user needs.

[0067] by Figure 1 Taking the water supply device shown as an example, the water supply device provided in the embodiment of the present application may include a water inlet 110, a hot water tank 120, a normal temperature water tank 130, a water outlet 140 and a main controller (not shown in the figure), wherein the water inlet 110 is connected to an external water source, a hot water tank 120 and a normal temperature water tank 130 through pipes, respectively, and the water inlet 110 is used to transport the normal temperature water supplied by the external water source to the hot water tank 120 and the normal temperature water tank 130, or the water inlet 110 can also store or process the normal temperature water supplied by the external water source, and then transport the treated normal temperature water to the hot water tank 120 and the normal temperature water tank 130.

[0068] The water outlet 140 is provided with a mixed water zone, the inlet of which can be connected to a hot water pipe and a normal temperature water pipe, and the outlet of which is provided with a water outlet for discharging the mixed water of a certain temperature in the mixed water zone.

[0069] The hot water tank 120 can be used to heat the room temperature water delivered from the water inlet 110 and store the hot water, and deliver the hot water to the mixed water area through the above-mentioned hot water pipeline.

[0070] The normal temperature water tank 130 can be used to store the normal temperature water delivered from the water inlet 110, and to deliver the normal temperature water to the mixed water area through the above-mentioned normal temperature water pipeline.

[0071] In order to accurately control the flow of hot water and normal temperature water, a hot water flow controller 121 can be provided on the hot water pipe, and a normal temperature water flow controller 131 can be provided on the normal temperature water pipe. The two flow controllers can control the flow of hot water and normal temperature water flowing into the mixed water area, thereby controlling the mixing ratio of hot water and normal temperature water in the mixed water area to obtain water of the temperature desired by the user.

[0072] In the embodiment of the present application, the water temperature can also be detected by a sensor. For example, a temperature sensor, i.e., a first sensor 132, is provided at the normal temperature water tank 130 to detect the temperature of the normal temperature water stored in the normal temperature water tank 130. It can be understood that the temperature of the normal temperature water also changes with the change of seasons. For example, in summer, the temperature of the normal temperature water is higher, and in winter, the temperature of the normal temperature water is lower.

[0073] In some other embodiments, the first sensor 132 may also be disposed in a pipe between the water inlet 110 and the normal temperature water tank 130 or on a normal temperature water pipe, and may also detect the normal temperature water temperature.

[0074] Similarly, a temperature sensor, namely a second sensor 142, can be set at the water outlet 140 to detect the temperature of the mixed water in the mixed water zone. Since the mixed water in the mixed water zone is directly discharged for use by users, the temperature of the mixed water in the mixed water zone can also be considered as the actual water outlet temperature of the water supply device. Therefore, the main controller of the water supply device can be used to adjust the hot water flow rate and the normal temperature water flow rate flowing to the mixed water zone according to the deviation between the actual water outlet temperature and the target water outlet temperature, so that the actual water outlet temperature is the same as the target water outlet temperature set by the user.

[0075] In an embodiment of the present application, the water outlet 140 can be a switch such as a faucet or a water valve that can control the water flow; the hot water flow controller 121 and the normal temperature water flow controller 131 can adopt any existing water pump, brushless pump, etc., and a first solenoid valve S1 can also be provided on the hot water pipe, such as the part of the hot water pipe close to the mixed water area, and a second solenoid valve S2 can also be provided on the normal temperature water pipe, such as the part of the normal temperature water pipe close to the mixed water area, to further control the flow of the fluid on the corresponding pipe through the solenoid valve.

[0076] like Figure 2As shown, in some embodiments of the present application, a heating module 123 can be provided at the hot water tank 120, and the room temperature water delivered from the water inlet 110 is heated by the heating module 123, so that the hot water in the hot water tank 120 is maintained at a boiling point. It can be understood that when the hot water in the hot water tank 120 reaches the boiling point, the heating module 123 can operate at a low power to keep the hot water warm at the boiling point.

[0077] Similarly, a temperature sensor, namely a third sensor 122, can also be provided at the hot water tank 120 to detect the boiling point water temperature of the hot water in the hot water tank 120. It can be understood that the boiling point of water is different in areas with different altitudes, so the third sensor 122 can detect the boiling point water temperature of the current area.

[0078] In this embodiment, the heating module 123 can be an existing heating device such as an electric heating wire or a heating wire, and the temperature sensor can adopt an existing temperature detection device such as a thermistor or a thermocouple, including but not limited to a negative temperature coefficient (NTC) temperature sensor, a positive temperature coefficient (PTC) temperature sensor, etc.

[0079] In the embodiment of the present application, the main controller of the water supply device can implement a water outlet temperature adjustment method to make the actual water outlet temperature at the water outlet the same as the target water outlet temperature set by the user.

[0080] like Figure 3 As shown, Figure 3 1 is a flow chart of the method for regulating the outlet water temperature provided in the embodiment of the present application. It should be noted that although the logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in a different order than that here. The method for regulating the outlet water temperature provided in the present application may specifically include the following multiple steps.

[0081] Step S301, obtaining the normal water temperature under the current environment and the target water outlet temperature at the water outlet.

[0082] According to the aforementioned water supply device, it can be known that a temperature sensor can be provided at the normal temperature water tank to detect the normal temperature water temperature. The temperature sensor can sample the normal temperature water temperature in the normal temperature water tank in real time based on a preset sampling frequency. For example, the temperature sensor can be set to sample data once per second, and the normal temperature water temperature at the corresponding moment can be obtained every 1 second. It can be understood that the sampling frequency of the temperature sensor can be determined according to actual needs or actual application scenarios, and is not specifically limited here.

[0083] In some specific implementations, the temperature sensor can upload the sampled normal temperature water temperature to the main controller based on a preset upload frequency, that is, the main controller can obtain the normal temperature water temperature in the current environment based on the upload frequency.

[0084] In some other specific implementations, the main controller may also establish a communication link with the temperature sensor based on a preset access frequency to obtain the normal temperature of the water from the temperature sensor.

[0085] It is understandable that the temperature of ambient water is different in different seasons or under different environmental conditions. For example, in summer or in production workshops with more heating equipment, the temperature of ambient water will be higher, while in winter or in places with sufficient air conditioning, the temperature of ambient water will be relatively low.

[0086] The target water outlet temperature at the water outlet can be the temperature set by the user. For example, the user can set the target water outlet temperature through the interactive interface of the water supply device, so that the main controller obtains the target water outlet temperature; or, the user can also set the target water outlet temperature through an application on a terminal device that is connected to the main controller for communication, so that the main controller obtains the target water outlet temperature.

[0087] Step S302, according to the normal temperature water temperature and the target water outlet temperature, determine the first initial working parameter of the hot water flow controller and the second initial working parameter of the normal temperature water flow controller, and control the hot water flow controller to operate based on the first initial working parameter to control the amount of hot water flowing to the water outlet, and control the normal temperature water flow controller to operate based on the second initial working parameter to control the amount of normal temperature water flowing to the water outlet.

[0088] According to the description of step S301, it can be known that the temperature of the normal temperature water will vary with the change of the environment, and the temperature of the normal temperature water will affect the temperature of the mixed water in the mixed water zone. Therefore, in the embodiment of the present application, the optional working parameters of the hot water flow controller and the normal temperature water flow controller can be preliminarily determined based on the normal temperature water temperature detected in the current environment, and then the corresponding working parameters can be selected from the optional working parameters according to the target water outlet temperature as the initial working parameters of the hot water flow controller and the normal temperature water flow control, so as to control the water flow through the two flow controllers, thereby regulating the mixing ratio of hot water and normal temperature water in the mixed water zone.

[0089] It can be understood that the optional working parameters of the aforementioned hot water flow controller and normal temperature water flow controller and the selection of the initial working parameters can be determined based on past experience or multiple experiments.

[0090] By controlling the hot water flow controller and the normal temperature water flow controller to work based on the corresponding initial working parameters, the amount of hot water flowing from the hot water pipe to the mixed water area and the amount of normal temperature water flowing from the normal temperature water pipe to the mixed water area can be controlled.

[0091] For example, both the hot water flow controller and the normal temperature water flow controller can be brushless pumps. The liquid flow passing through the brushless pumps can be controlled by controlling the on-duty cycle of the brushless pumps. Therefore, the first initial operating parameter and the second initial operating parameter can be the corresponding on-duty cycles of the two flow controllers.

[0092] Specifically, after the main controller determines the first initial working parameters of the hot water flow controller and the second initial working parameters of the normal temperature water flow controller according to the normal temperature water temperature and the target water outlet temperature, it can generate a first pulse control signal according to the first initial working parameters and generate a second pulse control signal according to the second initial working parameters.

[0093] It can be understood that the first pulse control signal carries the initial duty cycle of the hot water flow controller, and the second pulse control signal carries the initial duty cycle of the normal temperature water flow controller, so that the hot water flow controller and the normal temperature water flow controller operate based on the corresponding initial duty cycles, thereby controlling the amount of hot water flowing from the hot water tank to the mixed water zone and the amount of normal temperature water flowing from the normal temperature water tank to the mixed water zone.

[0094] Step S303, obtaining the actual water outlet temperature at the water outlet, and adjusting the hot water flow controller and / or the normal temperature water flow controller according to the actual water outlet temperature and the target water outlet temperature, so that the actual water outlet temperature is the same as the target water outlet temperature.

[0095] According to the aforementioned water supply device, it can be known that a temperature sensor can be provided at the water outlet end for detecting the mixed water temperature of the mixed water zone, that is, the actual water outlet temperature. When the actual water outlet temperature is different from the target water outlet temperature set by the user or the deviation between the two is greater than the allowable error threshold, the main controller can adjust the working parameters of at least one of the hot water flow controller and the normal temperature water flow controller based on the deviation, thereby adjusting the amount of hot water and / or normal temperature water flowing to the mixed water zone, so as to achieve the purpose of adjusting the actual water outlet temperature, so that the actual water outlet temperature is the same as the target water outlet temperature or the deviation between the two is less than the allowable error threshold.

[0096] In an embodiment of the present application, first, a first initial working parameter of a hot water flow controller and a second initial working parameter of a normal temperature water flow controller are determined according to the normal temperature water temperature in the current environment and the set target water outlet temperature at the water outlet. After the hot water flow controller works based on the first initial working parameter and the normal temperature water flow controller works based on the second initial working parameter, the hot water flow controller and / or the normal temperature water flow controller are adjusted based on the deviation between the actual water outlet temperature at the water outlet and the target water outlet temperature, thereby achieving fast, accurate and stepless adjustment of the water outlet temperature at the water outlet. Compared with the related art of adjusting the water volume ratio of hot water and cold water by comparing the target water outlet temperature, hot water temperature and cold water temperature, the present application firstly performs coarse adjustment on the two flow controllers according to the normal temperature water temperature and the target water outlet temperature, and then performs fine adjustment on at least one of the two flow controllers based on the deviation between the actual water outlet temperature and the target water outlet temperature, thereby achieving fast adjustment of the water outlet temperature at the water outlet and improving user experience.

[0097] Next, continue to Figure 3 Each step shown and a specific implementation method that may be used in practical applications are described in detail.

[0098] In some embodiments of the present application, determining the first initial operating parameter of the hot water flow controller and the second initial operating parameter of the normal temperature water flow controller according to the normal temperature water temperature and the target water outlet temperature may further include:

[0099] According to the normal temperature water temperature, the first preset parameter group and the second preset parameter group are determined; the first preset parameter group is the preset working parameters corresponding to the hot water flow controller at multiple preset water outlet temperatures, and the second preset parameter group is the preset working parameters corresponding to the normal temperature water flow controller at multiple preset water outlet temperatures;

[0100] According to the target outlet water temperature and a plurality of preset outlet water temperatures, one of the preset operating parameters in the first preset parameter group is determined as the first initial operating parameter, and one of the preset operating parameters in the second preset parameter group is determined as the second initial operating parameter.

[0101] Before applying the method of the embodiment of the present application, the actual water outlet temperature at the water outlet can be controlled to be a plurality of preset water outlet temperatures under at least two different ambient temperatures, and the working parameters of the hot water flow controller and the normal temperature water flow controller corresponding to each preset water outlet temperature can be recorded in association at each ambient temperature.

[0102] For example, assuming that the ambient temperature is normal temperature (such as 20°C) and cold climate (such as 5°C), and the preset water outlet temperatures are 30°C, 60°C and 90°C, the actual water outlet temperature at the water outlet can be controlled to be 30°C, 60°C and 90°C respectively under normal temperature (such as 20°C) and cold climate (such as 5°C). Based on the proportional-integral-derivative (PID) method, the working parameters of the hot water flow controller and the normal temperature water flow controller, i.e., the opening duty cycle, are adjusted to obtain the working parameters corresponding to each preset water outlet temperature under normal temperature and cold climate, as shown in Table 1, which is a temperature and parameter comparison table.

[0103] Table 1 Temperature and parameter comparison table

[0104]

[0105] The temperature and parameter comparison table can be stored in a memory. When the initial working parameters of the two flow controllers need to be determined, the main controller can access the comparison table stored in the memory and determine the initial working parameters of the flow controllers based on the associated corresponding relationship.

[0106] For example, if the normal temperature water temperature is 20°C and the target water outlet temperature is 30°C, then according to the temperature and parameter comparison table, it can be determined that the first preset parameter group corresponding to the normal temperature water temperature is K 30 , K 60 and K 90 , the second preset parameter group is P 30 , P 60 and P 90 , and then select K corresponding to the target water outlet temperature of 30°C from the first preset parameter group and the second preset parameter group. 30 As the first initial working parameter and P 30 As the second initial working parameter.

[0107] It can be understood that the number of ambient temperatures and preset water outlet temperatures set during the preliminary experiment can be determined according to actual conditions. The more ambient temperatures and preset water outlet temperatures there are, the smaller the deviation between the actual water outlet temperature and the target water outlet temperature after the initial adjustment, so that the actual water outlet temperature can be made to coincide with the target water outlet temperature more quickly in the subsequent adjustment process.

[0108] For example, the ambient temperature can also be set to 0°C, 15°C, 30°C, etc., and the preset water outlet temperature can also be set to 45°C, 75°C, 85°C, etc. The specific setting can be determined according to actual needs and is not limited here.

[0109] In some embodiments of the present application, if the actual ambient temperature is different from the ambient temperature set in the comparison table, determining the first preset parameter group and the second preset parameter group according to the normal temperature water temperature may further include:

[0110] Comparing the normal temperature water temperature with at least two different ambient temperatures, and determining the ambient temperature with the smallest difference between the normal temperature water temperature and the at least two different ambient temperatures as the target ambient temperature;

[0111] The preset working parameters of the hot water flow controller corresponding to each preset water outlet temperature associated with the target ambient temperature are determined as a first preset parameter group, and the preset working parameters of the normal temperature water flow controller are determined as a second preset parameter group.

[0112] In this scenario, the detected normal temperature water temperature can be compared with each ambient temperature in the comparison table. For example, the normal temperature water temperature can be subtracted from each ambient temperature in pairs, and the smallest difference can be found among all the differences. The ambient temperature corresponding to the difference can be considered to be the ambient temperature closest to the normal temperature water temperature. It can be understood that the purpose of the difference is to determine the value of the ambient temperature that is closest to the normal temperature water temperature. Therefore, when the difference is a negative number, its absolute value can be taken. Then, the ambient temperature corresponding to the smallest difference can be determined as the target ambient temperature, and the working parameters corresponding to each preset water outlet temperature associated with the target ambient temperature are determined as the first preset parameter group and the second preset parameter group.

[0113] For example, if the ambient temperature is 5°C, 20°C and 30°C, and the normal water temperature detected by the temperature sensor is 18°C, the main controller can make a difference between the normal water temperature of 18°C ​​and the ambient temperature of 5°C, the ambient temperature of 20°C and the ambient temperature of 30°C, respectively, and the differences (absolute values) are 13°C, 2°C and 12°C, respectively. At this time, the ambient temperature of 20°C corresponding to the difference of 2°C can be determined as the target ambient temperature, and then the working parameters (such as K) of the hot water flow controller corresponding to each preset water outlet temperature (such as 30°C, 45°C, 60°C, 75°C, 85°C, etc.) associated with the ambient temperature of 20°C are set. 30 , K 45 , K 60 , K 75 , K 85 etc.) are determined as the first preset parameter group, and the working parameters of the normal temperature water flow controller (such as P 30 , P 45 , P 60 , P 75 , P 85 etc.) are determined as the second preset parameter group.

[0114] In some embodiments of the present application, the target outlet water temperature may be different from the preset outlet water temperature set in the comparison table. Therefore, according to the target outlet water temperature and the plurality of preset outlet water temperatures, determining one of the preset operating parameters in the first preset parameter group as the first initial operating parameter and one of the preset operating parameters in the second preset parameter group as the second initial operating parameter may further include:

[0115] Comparing the target water outlet temperature with a plurality of preset water outlet temperatures, and determining the preset water outlet temperature with the smallest difference between the target water outlet temperature and the preset water outlet temperature as the reference water outlet temperature;

[0116] The preset operating parameter corresponding to the reference outlet water temperature in the first preset parameter group is determined as the first initial operating parameter, and the preset operating parameter corresponding to the reference outlet water temperature in the second preset parameter group is determined as the second operating parameter.

[0117] Similar to the method for determining the target ambient temperature, in an embodiment of the present application, when the target water outlet temperature is different from each preset water outlet temperature, the target water outlet temperature can be compared with each preset water outlet temperature in the comparison table. For example, the target water outlet temperature is subtracted from each preset water outlet temperature in pairs, and the smallest difference is found among all the differences. The preset water outlet temperature corresponding to the difference can be considered as the water outlet temperature closest to the target water outlet temperature. Similarly, the purpose of the difference is to determine the value of the preset water outlet temperature that is closest to the target water outlet temperature. Therefore, when the difference is a negative number, its absolute value can be taken. Then, the preset water outlet temperature corresponding to the smallest difference can be determined as the reference water outlet temperature, and the preset working parameter corresponding to the reference water outlet temperature in the first preset parameter group is determined as the first initial working parameter for controlling the hot water flow controller to control the hot water flow, and the preset working parameter corresponding to the reference water outlet temperature in the second preset parameter group is determined as the second initial working parameter for controlling the normal temperature water flow controller to control the normal temperature water flow.

[0118] For example, the target outlet water temperature is set to 48°C, and the preset outlet water temperatures are 30°C, 45°C, 60°C, 75°C, and 85°C. The main controller can respectively subtract the target outlet water temperature 48°C from the preset outlet water temperature 30°C, the preset outlet water temperature 45°C, the preset outlet water temperature 60°C, the preset outlet water temperature 75°C, and the preset outlet water temperature 85°C, and obtain the differences (absolute values) of 18°C, 3°C, 12°C, 27°C, and 37°C, respectively. At this time, the preset outlet water temperature 45°C corresponding to the difference of 3°C can be determined as the reference outlet water temperature, and then the working parameter K of the hot water flow controller corresponding to the preset outlet water temperature 45°C can be set. 45 The first initial working parameter is determined as the first initial working parameter, and the working parameter P of the normal temperature water flow controller corresponding to the preset water outlet temperature of 45°C is set. 45Determined as the second initial working parameter, to control the hot water flow controller and the normal temperature water flow controller respectively, so that the actual water outlet temperature in the coarse adjustment stage can be close to the target water outlet temperature, thereby facilitating subsequent rapid temperature adjustment.

[0119] In some embodiments of the present application, when it is detected that the actual water outlet temperature at the water outlet is different from the set target water outlet temperature or the deviation between the two is greater than the allowable error threshold, the working parameters of the hot water flow controller and the normal temperature water flow controller, i.e., the opening duty cycle, can be adjusted by the PID control method so that the actual water outlet temperature is the same as the target water outlet temperature.

[0120] For example, assuming that the target water outlet temperature set by the user is SetTemper, and the current actual water outlet temperature collected by the temperature sensor at the water outlet is WaterTemper, the PID adjustment error Error = SetTemper-WaterTemper can be defined. It can be understood that WaterTemper will change in real time with the adjustment of hot water flow and normal temperature water flow. The integral link is recorded as ErrSum = ErrSum + Error, and the differential link is recorded as ErrDiffer = Error-LastError, where LastError is the previous adjustment error (SetTemper-WaterTemper') in the error adjustment. Therefore, the PID adjustment formula of the hot water flow controller can be defined as KX = C0*Error + C1*ErrSum + C2*ErrDiffer, where C0, C1, and C2 are the proportional integral differential parameters of the hot water flow controller respectively; similarly, the adjustment formula of the normal temperature water flow controller can be defined as PX = D0*Error + D1*ErrSum + D2*ErrDiffer, where D0, D1, and D2 are the proportional integral differential parameters of the normal temperature water flow controller respectively.

[0121] In some embodiments of the present application, in order to make the actual outlet water temperature the same as the target outlet water temperature more quickly, adjusting the hot water flow controller and / or the normal temperature water flow controller according to the actual outlet water temperature and the target outlet water temperature may further include:

[0122] If the actual outlet water temperature is lower than the target outlet water temperature, based on the difference between the actual outlet water temperature and the target outlet water temperature, the opening duty cycle of the hot water flow controller is increased to increase the amount of hot water flowing to the outlet end;

[0123] If the actual outlet water temperature is greater than the target outlet water temperature, the opening duty cycle of the normal temperature water flow controller is increased based on the difference between the actual outlet water temperature and the target outlet water temperature to increase the amount of normal temperature water flowing to the outlet.

[0124] In an embodiment of the present application, when the actual water outlet temperature is different from the target water outlet temperature, the duty cycle of the hot water flow controller or the normal temperature water flow controller can be adjusted individually, or the duty cycles of the hot water flow controller and the normal temperature water flow controller can be adjusted at the same time. The specific duty cycle can be determined based on the actual application scenario and user needs, and is not limited here.

[0125] In order to meet the rapid adjustment of the outlet water temperature and ensure the outlet water flow rate, in the embodiment of the present application, one of the hot water flow controller and the normal temperature water flow controller can be selected for adjustment according to the relationship between the actual outlet water temperature and the target outlet water temperature.

[0126] For example, if the target outlet water temperature is 48°C, when the hot water flow controller operates based on the first initial working parameter and the normal temperature water flow controller operates based on the second initial working parameter, the actual outlet water temperature detected at the outlet is 45°C. Since the target outlet water temperature 48°C> the actual outlet water temperature 45°C, the working parameters of the normal temperature water flow controller can be maintained unchanged at this time, and the hot water flow controller can be adjusted to increase its opening duty cycle, so that the hot water flow to the mixed water area increases, thereby increasing the actual outlet water temperature. In addition, since the hot water in the hot water tank is always boiling hot water, the actual outlet water temperature can quickly complete the closed loop and reach the target outlet water temperature set by the user while ensuring the outlet water flow. Figure 4 As shown, it is the real-time data of detecting the actual outlet water temperature when the target outlet water temperature is 48°C, wherein the sampling frequency of the temperature sensor is to sample the outlet water temperature at the outlet end once every 100ms.

[0127] Similarly, if the target water outlet temperature is 55°C, when the hot water flow controller operates based on the first initial working parameters and the normal temperature water flow controller operates based on the second initial working parameters, the actual water outlet temperature at the water outlet is detected to be 60°C. Since the target water outlet temperature of 55°C < the actual water outlet temperature of 60°C, the working parameters of the hot water flow controller can be maintained unchanged at this time, and the normal temperature water flow controller can be adjusted to increase its opening duty cycle, so that the flow rate of normal temperature water flowing to the mixed water area increases, thereby reducing the actual water outlet temperature. In this way, the actual water outlet temperature can quickly complete the closed loop and reach the target water outlet temperature set by the user while ensuring the water outlet flow rate.

[0128] It is worth noting that if the target water outlet temperature is high, such as exceeding 98°C, hot water in a boiling point state can be directly provided. At this time, you can choose to close the normal temperature water flow controller to control the direct outlet of hot water in a boiling point state to provide hot water with a water temperature higher than 98°C; if the target water outlet temperature is low, such as below 30°C, normal temperature water in a normal temperature state can be directly provided. At this time, you can choose to close the hot water flow controller to control the direct outlet of normal temperature water to provide normal temperature water with a water temperature lower than 30°C.

[0129] The above is a description of the water outlet temperature adjustment method of the embodiment of the present application. In order to facilitate better implementation of the water outlet temperature adjustment method provided by the present application, the present application also provides a water purifier.

[0133] The controller 601 can control the water purifier 602 to implement the present application as follows Figure 2 Corresponding to the outlet water temperature adjustment method in any embodiment, therefore, the present application can be implemented as follows Figure 2 The beneficial effects that can be achieved by the outlet water temperature adjustment method in any embodiment are detailed in the previous description and will not be repeated here.

[0134] The technical solution of the present application is described below in conjunction with specific application scenarios to facilitate understanding.

[0135] Application scenario 1

[0136] The user needs to drink 40℃ warm water. After the target water outlet temperature of the water purifier is set to 40℃, the main controller of the water purifier determines the first initial duty cycle of the hot water flow controller and the second initial duty cycle of the normal temperature water flow controller according to the normal temperature water temperature detected by the first sensor and the target water outlet temperature of 40℃, and then controls the hot water flow controller to operate based on the first initial duty cycle and the normal temperature water flow controller to operate based on the second initial duty cycle; the second sensor detects the actual water outlet temperature at the water outlet, and the main controller dynamically adjusts the opening duty cycle of the hot water flow controller and the normal temperature water flow controller according to the deviation between the actual water outlet temperature and the target water outlet temperature, thereby controlling the mixing ratio of hot water and normal temperature water in the mixing water area of ​​the water outlet, so that the actual water outlet temperature quickly becomes the same as the target water outlet temperature.

[0137] Application scenario 2

[0138] In the cold winter, users need 80℃ hot water to prepare beverages. After the target water outlet temperature of the water purifier is set to 80℃, the main controller of the water purifier determines that it is currently in a cold ambient temperature based on the normal temperature water temperature of 5℃ detected by the first sensor, and obtains the duty cycle parameters of the hot water flow controller and the normal temperature water flow controller corresponding to each preset water outlet temperature when the preset ambient temperature is 5℃, and then determines the preset water outlet temperature with the smallest difference from the target water outlet temperature of 80℃ as the reference water outlet temperature, determines the duty cycle parameter of the hot water flow controller corresponding to the reference water outlet temperature as the first initial duty cycle, and determines the duty cycle parameter of the normal temperature water flow controller corresponding to the reference water outlet temperature as the second initial duty cycle, and controls the operation of the two flow controllers respectively.

[0139] The second sensor detects the actual water outlet temperature at the water outlet of the water purifier. If the actual water outlet temperature is greater than the target water outlet temperature, the first initial duty cycle of the hot water flow controller is maintained unchanged, and the second initial duty cycle of the normal temperature water flow controller is gradually increased, and the normal temperature water flow rate is increased, thereby reducing the actual water outlet temperature, so that the actual water outlet temperature quickly becomes the same as the target water outlet temperature; if the actual water outlet temperature is lower than the target water outlet temperature, the second initial duty cycle of the normal temperature water flow controller is maintained unchanged, and the first initial duty cycle of the hot water flow controller is gradually increased, and the hot water flow rate is increased, thereby raising the actual water outlet temperature, so that the actual water outlet temperature quickly becomes the same as the target water outlet temperature.

[0140] Application scenario three

[0141] In the factory, workers want to drink 35℃ warm water. After the target water outlet temperature of the water purifier is set to 35℃, the main controller of the water purifier determines that it is currently at normal ambient temperature based on the normal water temperature of 27℃ detected by the first sensor. The preset ambient temperatures are 25℃ and 40℃. Then, the duty cycle parameters of the hot water flow controller and the normal temperature water flow controller corresponding to each preset water outlet temperature when the ambient temperature is 25℃ are obtained, and the duty cycle parameters of the hot water flow controller corresponding to the preset water outlet temperature of 35℃ are determined as the first initial duty cycle, and the duty cycle parameters of the normal temperature water flow controller corresponding to the preset water outlet temperature of 35℃ are determined as the second initial duty cycle, and the operation of the two flow controllers are controlled respectively.

[0142] The second sensor detects that the actual water outlet temperature at the water outlet of the water purifier is 38°C, which is higher than the target water outlet temperature of 35°C. Therefore, the main controller controls the first initial duty cycle of the hot water flow controller to decrease, and the second initial duty cycle of the normal temperature water flow controller to increase, thereby reducing the amount of hot water and increasing the normal temperature water flow to lower the actual water outlet temperature, so that the actual water outlet temperature quickly reaches the target water outlet temperature.
