[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The following describes, with reference to the accompanying drawings, a method for predicting the ambient temperature of an instant hot water device, a computer-readable storage medium, an apparatus for predicting the ambient temperature of an instant hot water device, and an instant hot water device according to embodiments of the present invention.

[0035] Specifically, in some embodiments of the present invention, Figure 1 As shown, the instant hot drinking water device 1000 includes a water purifier 100 and an instant heating system 200. The instant heating system 200 heats the water supplied to the water purifier 100 through a tankless pipeline machine.

[0036] Figure 2 1 is a flow chart of a method for predicting the ambient temperature of an instant hot water drinking water device according to an embodiment of the present invention.

[0037] Specifically, in some embodiments of the present invention, Figure 2 As shown, the ambient temperature prediction method of the instant hot water device includes:

[0038] S101, obtaining an ambient temperature estimation strategy of an instant hot water device, wherein the ambient temperature estimation strategy includes an inlet water temperature estimation strategy and / or an outlet water temperature estimation strategy.

[0039] It can be understood that in this embodiment of the present invention, the ambient temperature estimation strategy is preset in the temperature control program of the instant hot water device, wherein the water inlet temperature estimation strategy specifically adopts the water inlet temperature of the instant hot water system to characterize the current ambient temperature of the instant hot water device, and the water outlet temperature estimation strategy specifically adopts the water outlet temperature of the instant hot water system to characterize the current ambient temperature of the instant hot water device.

[0040] S102, obtaining a judgment parameter of the ambient temperature, wherein the judgment parameter includes an inlet water temperature and / or an outlet water temperature of the instant heating system.

[0041] It can be understood that, in this embodiment of the present invention, the water inlet temperature of the instant heating system is obtained through the water inlet temperature sensor and / or the water outlet temperature of the instant heating system is obtained through the water outlet temperature sensor.

[0042] S103, predicting the current ambient temperature of the instant hot water device according to the ambient temperature estimation strategy and the judgment parameters.

[0043] It is understandable that in this embodiment of the present invention, the current ambient temperature of the instant hot water device is predicted by combining the water inlet temperature estimation strategy with the water inlet temperature of the instant hot water system and / or the current ambient temperature of the instant hot water device is predicted by combining the water outlet temperature estimation strategy with the water outlet temperature of the instant hot water system. Thus, more accurate temperature control accuracy is achieved without additionally increasing the equipment cost, ensuring the temperature control stability of the instant hot water device.

[0044] Furthermore, in some embodiments of the present invention, the current ambient temperature of the instant hot water device is predicted based on the ambient temperature estimation strategy and judgment parameters, including: if the ambient temperature estimation strategy is an inlet water temperature estimation strategy, the current ambient temperature of the instant hot water device is predicted based on the inlet water temperature of the instant heating system.

[0045] It can be understood that in this embodiment of the present invention, when the ambient temperature estimation strategy is the water inlet temperature estimation strategy, the current ambient temperature of the instant hot water device is predicted based on the water inlet temperature of the instant hot water system. Specifically, the current ambient temperature T of the instant hot water device is predicted using the water inlet temperature sensor. 环 .

[0046] It should be noted that, in the above-mentioned embodiment of the present invention, since the water inlet temperature sensor detects the water inlet temperature (or water source temperature) of the instant hot water system, and the water inlet usually comes from a water purifier and does not pass through a heating link, the water inlet temperature is basically consistent with the ambient temperature. At this time, the water inlet temperature of the instant hot water system is directly used as the current ambient temperature of the instant hot water equipment.

[0047] Furthermore, in some embodiments of the present invention, the current ambient temperature of the instant hot water device is predicted based on the ambient temperature estimation strategy and judgment parameters, including: if the ambient temperature estimation strategy is a water outlet temperature estimation strategy, the current ambient temperature of the instant hot water device is predicted based on the water outlet temperature of the instant heating system.

[0048] It can be understood that in this embodiment of the present invention, when the ambient temperature estimation strategy is the water outlet temperature estimation strategy, the current ambient temperature of the instant hot water device is predicted based on the water outlet temperature of the instant hot water system. Specifically, the current ambient temperature T of the instant hot water device is predicted using the water outlet temperature sensor. 环 .

[0049] It should be noted that, in the above-mentioned embodiment of the present invention, since the outlet water temperature sensor detects the outlet water temperature of the instant heating system (unheated outlet water or heated outlet water), it is necessary to perform corresponding processing on the outlet water temperature detected by the outlet water temperature sensor so that the outlet water temperature detected by the outlet water temperature sensor accurately represents the ambient temperature.

[0050] The specific processing method of the outlet water temperature in the embodiments of the present invention is described below in combination with some embodiments of the present invention:

[0051] Furthermore, in some embodiments of the present invention, the current ambient temperature of the instant hot water device is predicted based on the water outlet temperature, including: if the water tank pipeline machine does not heat for a first preset time, the current ambient temperature of the instant hot water device is predicted based on the current water outlet temperature of the instant heating system.

[0052] It should be understood that when the instant heating pipe is not heated, the outlet water temperature of the instant heating system is T 出 Will gradually approach the current ambient temperature T of the instant hot water equipment 环 , and when the instantaneous heating pipe does not heat for a period of time exceeding the corresponding time, the outlet water temperature of the instantaneous heating system T 出 Current ambient temperature T of basic and instant hot water equipment 环 At this time, it can be considered that T 出 =T 环 Therefore, in this embodiment of the present invention, when it is detected that the water tankless pipeline machine does not heat for a first preset time (i.e., the heat pipe maintains 0w power for more than m time), the current ambient temperature of the instant hot water equipment is predicted as the current water outlet temperature of the instant hot water system detected by the water outlet temperature sensor.

[0053] Optionally, in the above-mentioned embodiment of the present invention, the value of the first preset time may be calibrated accordingly according to the equipment parameters of the instant hot water drinking equipment. For example, the first preset time may preferably be 1 hour.

[0054] Further, in some embodiments of the present invention, Figure 3 As shown, after predicting the current ambient temperature of the instant hot water device according to the current water outlet temperature of the instant hot water system, the method further includes:

[0055] S201, obtaining multiple outlet water temperatures of the instant heating system within a first preset sampling period.

[0056] It can be understood that in this embodiment of the present invention, after predicting the current ambient temperature of the instant hot water device based on the current water outlet temperature of the instant hot water system, multiple water outlet temperatures of the instant hot water system within the first preset sampling period are obtained through the water outlet temperature sensor.

[0057] Optionally, in the above embodiment of the present invention, the first preset sampling period may be one period for every 100 pieces of water outlet temperature data collected.

[0058] S202: Obtain a first ambient temperature fitting curve according to a plurality of outlet water temperatures of the instant heating system within a first preset sampling period and a least squares formula.

[0059] It can be understood that in this embodiment of the present invention, multiple outlet water temperatures of the instant heating system within the first preset sampling period can be substituted into the least squares formula in real time to obtain a value where the horizontal axis is time t and the vertical axis is ambient temperature T 环 The first ambient temperature fitting curve is used to characterize the current ambient temperature of the instant hot water device:

[0060] T 环 =f(t)=kt+b……①

[0061] in, b=T 平均 -kt 平均 , t i is the i-th second, the initial t coordinate is 0, T i is the outlet water temperature at the ith second, t 平均 is the average value of all t coordinates, T 平均 is the average of all outlet water temperatures.

[0062] Furthermore, in some embodiments of the present invention, after obtaining the first ambient temperature fitting curve, the method also includes: if the water tank-less pipeline machine starts heating and continues for a second preset time after the heating ends, the current ambient temperature of the instant hot water equipment is predicted according to the first ambient temperature fitting curve.

[0063] It can be understood that in this embodiment of the present invention, when it is detected that the water tankless pipeline machine starts heating and continues for the second preset time after the heating ends, the current ambient temperature of the instant hot water device can be predicted according to the first ambient temperature fitting curve (i.e., the aforementioned formula ①). Specifically, by substituting the current time t into formula ①, the current ambient temperature T of the instant hot water device is predicted. 环 .

[0064] Optionally, in the above embodiment of the present invention, the value of the second preset time may be calibrated accordingly according to the equipment parameters of the instant hot water device. For example, the second preset time may preferably be 20 minutes.

[0065] Further, in some embodiments of the present invention, Figure 4 As shown, after predicting the current ambient temperature of the instant hot water device according to the first ambient temperature fitting curve, the method further includes:

[0066] S301, obtaining multiple outlet water temperatures of the instant heating system within a second preset sampling period.

[0067] It can be understood that after predicting the current ambient temperature of the instant hot water device according to the first ambient temperature fitting curve, multiple outlet water temperatures of the instant hot water system in the second preset sampling period are obtained through the outlet water temperature sensor. Specifically, the outlet water temperatures collected every minute are recorded and saved in a rolling manner. For example, the outlet water temperature collected this minute is 90°C, which is recorded as T 0 , the outlet water temperature 1 minute ago is T 1 , the outlet water temperature 2 minutes ago is T 2 , ..., and so on, the outlet water temperature n minutes ago is T n .

[0068] Optionally, in the above embodiment of the present invention, the second preset sampling period may be to collect the outlet water temperature data once every minute.

[0069] S302: Obtain an nth-order derivative of a current outlet water temperature of the instant heating system according to a plurality of outlet water temperatures of the instant heating system within a second preset sampling period.

[0070] It can be understood that each time the latest outlet water temperature is collected, the first, second, third, ..., nth order derivatives are calculated in real time (the origin is defined as the current time, the horizontal axis is time t, the positive half axis of the horizontal axis is the past time, the horizontal axis 1 is 1 minute ago, 2 is 2 minutes ago, and so on, the negative half axis is the future time, -1 is 1 minute in the future, -2 is two minutes in the future, and so on):

[0071] (1) Method for calculating the first-order derivative (taking △t = 1 (minutes)):

[0072] That is, T′ 1 =T 1 -T 2 ,T′ 2 =T 2 -T 3 ,……

[0073] And so on, and save the latest first-order derivative;

[0074] (2) Similarly, the method for calculating the second-order derivative is just to differentiate the first-order derivative again:

[0075] That is, T″ 1 =T′ 1 -T′ 2 ,T″ 2 =T′ 2 -T′ 3 ,…, and so on;

[0076] Then, the third-order derivative can be obtained by taking the derivative of the second-order derivative again, thereby obtaining the n-th-order derivative of the current outlet water temperature:

[0077] S303, obtaining a second ambient temperature fitting curve according to the nth-order derivative of the current outlet water temperature of the instant heating system and the Taylor formula.

[0078] It can be understood that, in this embodiment of the present invention, by substituting the nth-order derivative of the current outlet water temperature of the instant heating system into the Taylor formula: The second ambient temperature fitting curve (x 0 =0):

[0079]

[0080] Among them, T 0 is the current outlet water temperature, T′ 0 is the first-order derivative of the current outlet water temperature, T″ 0 is the second-order derivative of the current outlet water temperature, is the nth-order derivative of the current outlet water temperature, and t is the time to be predicted.

[0081] It should be noted that, in the above embodiment of the present invention, the origin of the second ambient temperature fitting curve is the current water outlet temperature, the positive half axis t is the (historical) water outlet temperature t minutes ago, and the negative half axis t is the (predicted) water outlet temperature t minutes later.

[0082] Furthermore, in some embodiments of the present invention, after obtaining the second ambient temperature fitting curve, the method also includes: if the water tank-free pipeline machine starts heating and continues for a third preset time after the heating ends, then predicting the current ambient temperature of the instant hot water equipment according to the second ambient temperature fitting curve, wherein the third preset time is greater than the second preset time.

[0083] It can be understood that in this embodiment of the present invention, when it is detected that the water tankless pipeline machine starts heating and continues for a third preset time after the heating ends, the current ambient temperature of the instant hot water device can be predicted according to the second ambient temperature fitting curve (i.e., the aforementioned formula ②). Specifically, by substituting the time required for the outlet water temperature to fall back to the ambient temperature into formula ②, the current ambient temperature T of the instant hot water device is predicted. 环 .

[0084] Optionally, in the above embodiment of the present invention, the value of the third preset time may be calibrated accordingly according to the equipment parameters of the instant hot water device. For example, the third preset time may preferably be 90 minutes.

[0085] Further, in some embodiments of the present invention, Figure 5 As shown, after predicting the current ambient temperature of the instant hot water drinking device, the method further includes:

[0086] S401, obtaining the operating parameters of the instant hot water system according to the current ambient temperature of the instant hot water device.

[0087] Optionally, in this embodiment of the present invention, the operating parameters of the instant heating system may include the operating power of the tankless pipeline machine and the operating time of the tankless pipeline machine.

[0088] S402, according to the operating parameters of the instant heating system, controlling the tankless pipeline machine to heat the water supply to the water purifier.

[0089] It should be understood that for instant hot water dispensers, the heating power and flow rate performed at different ambient temperatures are different. Therefore, in this embodiment of the present invention, the operation of the instant heating system is better controlled by accurately knowing the current ambient temperature of the instant hot water device, thereby ensuring the temperature control stability of the instant hot water device and improving user safety.

[0090] Combine the following Figure 6 The specific process of the method for predicting the ambient temperature of the instant hot water drinking equipment according to the embodiment of the present invention is described as follows:

[0091] For example, Figure 6 As shown, in a specific embodiment of the present invention, when the ambient temperature estimation strategy is the water inlet temperature estimation strategy, the water inlet temperature of the water inlet temperature sensor is directly used as the current ambient temperature of the instant hot water device. In addition, in another specific embodiment of the present invention, when the ambient temperature estimation strategy is the water outlet temperature estimation strategy, if the instant hot water pipe does not work for more than a first preset time (for example, 1 hour), the water outlet temperature of the water outlet temperature sensor is used as the current ambient temperature of the instant hot water device. If the instant hot water pipe starts to heat within a second preset time after the heating is completed (for example, from the beginning to the 20th minute after the heating is completed), the current ambient temperature of the instant hot water device is predicted by a first ambient temperature fitting curve determined based on a least squares formula. If the instant hot water pipe starts to heat within a third preset time after the heating is completed (for example, from the 20th minute to the 90th minute after the heating is completed), the current ambient temperature of the instant hot water device is predicted by a second ambient temperature fitting curve determined based on a Taylor formula. Thus, the ambient temperature acquisition method is covered in various situations such as when the instant hot water pipe is not heated, during heating, and after heating, and a better prediction result is achieved.

[0092] In summary, according to the ambient temperature prediction method of the instant hot water device in the embodiment of the present invention, the ambient temperature estimation strategy of the instant hot water device is obtained, wherein the ambient temperature estimation strategy includes the water inlet temperature estimation strategy and / or the water outlet temperature estimation strategy, and then, the judgment parameter of the ambient temperature is obtained, wherein the judgment parameter includes the water inlet temperature and / or the water outlet temperature of the instant hot water system, and the current ambient temperature of the instant hot water device is predicted according to the ambient temperature estimation strategy and the judgment parameter. Therefore, based on the judgment parameter of the ambient temperature combined with the ambient temperature estimation strategy, the current ambient temperature of the instant hot water device is accurately predicted, thereby achieving more accurate temperature control accuracy without additionally increasing the equipment cost, and ensuring the temperature control stability of the instant hot water device.

[0093] Based on the ambient temperature prediction method for the instant hot drinking water device of the aforementioned embodiment of the present invention, the embodiment of the present invention proposes a computer-readable storage medium, on which an ambient temperature prediction program for the instant hot drinking water device is stored. When the ambient temperature prediction program for the instant hot drinking water device is executed by a processor, the ambient temperature prediction method for the instant hot drinking water device of the aforementioned embodiment of the present invention is implemented.

[0094] It should be understood that the specific implementation of the computer-readable storage medium in the embodiment of the present invention refers to the specific implementation of the ambient temperature prediction method of the instant hot water equipment in the aforementioned embodiment of the present invention, and will not be repeated here to reduce redundancy.

[0095] In summary, according to the computer-readable storage medium of an embodiment of the present invention, through the ambient temperature prediction program of the instant hot water drinking equipment stored thereon, it is possible to achieve more accurate temperature control accuracy without increasing the equipment cost, thereby ensuring the temperature control stability of the instant hot water drinking equipment.
