It should be noted that the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
The instant heating device, the temperature prediction control method and device thereof, and the water treatment device provided by the embodiments of the present application are described in detail below with reference to fig. 1 to 16 through specific embodiments and application scenarios thereof.
First embodiment, fig. 1 shows one of the flow diagrams of the temperature prediction control method of an instant heating device according to the embodiment of the present invention. The temperature prediction control method comprises the following steps:
step S102, acquiring a plurality of historical detected water temperatures within a first preset time before the current time;
step S104, acquiring the current detected water temperature at the current time;
and step S106, determining the predicted water outlet temperature after the second preset time length at the current time according to the plurality of historical detected water temperatures and the current detected water temperature.
The temperature prediction control method of the instant heating device provided by the embodiment is used for the instant heating device, and the instant heating device is provided with main parts such as an instant heat pipe, a water pump and an outlet water temperature detection piece. In the actual application process of the instant heating device, due to the influence of multiple factors such as the response speed of the water pump, the change time of the water temperature, the response speed of the water outlet temperature detection piece and the like, namely a certain delay error exists between the actual water outlet temperature of the instant heating device and the detected water temperature detected by the water outlet temperature detection piece, so that the actual condition of the water outlet temperature is difficult to accurately control by a temperature control system of the instant heating device, the accuracy of the work control of the instant heating device is reduced, the conditions of overshoot, large temperature fluctuation and even water temperature runaway which cause boiling vaporization easily occur, the accuracy of the water outlet temperature of the instant heating device is reduced, and the water outlet effect of the instant heating device is further reduced.
Therefore, in the temperature prediction control method of the instant heating device proposed by the present embodiment, the currently detected water temperature of the instant heating device and a plurality of historically detected water temperatures of the instant heating device within a first preset time period before the current time are collected. Namely, the outlet water temperature of the heating device has certain regularity along with the change of time, and based on the regularity, a plurality of collected historical detected water temperatures and the current detected water temperature are processed to determine the current actual outlet water temperature of the heating device, namely, the detected water temperature (namely, the predicted outlet water temperature) of the water temperature detection piece after the second preset time length at the current time is determined. Therefore, the accuracy of determining the actual outlet water temperature of the instant heating device is ensured, in the temperature prediction control process of the subsequent instant heating device, the control error caused by the work delay of each part in the instant heating device is reduced, the accuracy of the work control of the instant heating device is improved, the outlet water effect of the instant heating device is improved, and the overall performance of the instant heating device is further improved.
The detection time interval corresponding to two adjacent historical detected water temperatures is a second preset time length, the first preset time length is N times of the second preset time length, and N is a positive integer greater than or equal to 2. That is, in this embodiment, the currently detected water temperature of the instant heating device and the plurality of historically detected water temperatures of the instant heating device within the first preset time period before the current time are collected at intervals of the second preset time period. Therefore, the water outlet process of the instant heating device is divided into a plurality of sections of temperature change processes, the time length of each section of temperature change process is limited to be equal, the consistency of the change rule of the water outlet temperature in each temperature change process is guaranteed, and when the current actual water outlet temperature (namely the predicted water outlet temperature) is determined through the historical temperature change process, the accuracy of the predicted water outlet temperature determination can be further guaranteed. In addition, the N is defined as a positive integer which is greater than or equal to 2, namely the first preset time period is defined to be at least twice of the second preset time period, namely the number of the historically detected water temperatures is defined to be at least two, so that the accuracy of the detected water temperature data in the historical temperature change process is ensured, and the accuracy of the predicted water temperature can be further ensured.
Further, the second preset time period is related to the delay time period of the outlet water temperature detection part of the instant heating device. Specifically, the value of the second preset time period is equal to the lag time of the detected water temperature detected by the outlet water temperature detection piece compared with the actual outlet water temperature of the instant heating device. After the lag time of the detected water temperature detected by the outlet water temperature detecting piece compared with the actual outlet water temperature of the instant heating device is obtained, the current detected water temperature of the instant heating device and a plurality of historical detected water temperatures of the instant heating device in a first preset time before the current time are obtained by taking the lag time as a time interval, and then the current actual outlet water temperature of the instant heating device is predicted according to the obtained plurality of detected water temperature data by means of the change rule of the outlet water temperature along with time so as to eliminate the influence of the delay time of the outlet water temperature detecting piece on the outlet water temperature detection.
It should be noted that the lag time between the detected water temperature detected by the outlet water temperature detector and the actual outlet water temperature of the instant heating device can be determined through a large number of experiments, and the obtained result is stored in the memory of the instant heating device in advance for later retrieval and use.
Illustratively, when a water outlet instruction input by a user is received, the lag time of a detected water temperature detected by a water outlet temperature detecting element pre-stored in a memorizer of the instant heating device compared with the actual water outlet temperature of the instant heating device is acquired as n (n is more than or equal to zero) seconds, the current detected water temperature of the water outlet temperature detecting element, the historical detected water temperature before the current time is n seconds, the historical detected water temperature before the current time is 2n seconds, the historical detected water temperature before the current time is 3n seconds and the like are acquired at preset time intervals of n seconds, and then the actual detected water temperature of the water temperature detecting element after the current time is n seconds is determined according to the acquired current detected water temperature and the historical detected water temperatures by the instant heating device according to the regularity of the water outlet temperature of the instant heating device along with time, namely the current actual water outlet temperature of the instant heating device is determined, so as to eliminate the influence of the delay time of the water outlet temperature detection piece on the water outlet temperature detection.

Wherein the detection time of the second historically-detected water temperature is earlier than the detection time of the first historically-detected water temperature, and the detection time of the first historically-detected water temperature is earlier than the current time (i.e., the detection time of the currently-detected water temperature). The detection time interval of the second historically detected water temperature, the first historically detected water temperature and the currently detected water temperature is the second preset time, namely the lag time of the detected water temperature detected by the water outlet temperature detecting element compared with the actual water outlet temperature of the instant heating device.
Illustratively, when a water outlet instruction input by a user is received, the lag time of the detected water temperature detected by a water outlet temperature detecting piece prestored in a memorizer of the instant heating device and the actual water outlet temperature of the instant heating device is acquired as n seconds, and then the instant heating device is acquired by taking the n seconds as a preset time intervalThe water temperature detection device comprises a current detected water temperature, a first historical detected water temperature n seconds before the current time, and a second historical detected water temperature 2n seconds before the current time.

Specifically, step S208 may be executed after step S206 is executed, or step S206 may be executed after step S208 is executed, and the execution sequence of step S206 and step S208 is not particularly limited.
In addition, the embodiment is described with the value of N being 2, that is, the number of the historically detected water temperatures being 2, and when N is another value, the current actual outlet water temperature of the heating device can be determined by the principle of the above method.

Ninth embodiment, fig. 9 shows a schematic block diagram of a temperature prediction control apparatus 900 of an instant heating apparatus according to an embodiment of the present invention. Wherein, this temperature prediction control device includes:
an obtaining module 902, configured to obtain a plurality of historical detected water temperatures within a first preset time period before a current time, and obtain a current detected water temperature at the current time;
and a processing module 904, configured to determine a predicted water outlet temperature after a second preset time period at the current time according to the plurality of historical detected water temperatures and the current detected water temperature.
The temperature prediction control device 900 of the instant heating device is used for the instant heating device, and the instant heating device is provided with main components such as a heat pipe, a water pump, an outlet water temperature detection piece and the like. In the actual application process of the instant heating device, due to the influence of multiple factors such as the response speed of the water pump, the water temperature change time (namely, the working time of the heating element), the response speed of the water outlet temperature detection element and the like, namely, a certain delay error exists between the actual water outlet temperature of the instant heating device and the detected water temperature detected by the water outlet temperature detection element, so that the actual condition of the water temperature is difficult to accurately control by a temperature control system of the instant heating device, the accuracy of the work control of the instant heating device is reduced, thereby being easy to generate overshoot, the condition of boiling vaporization caused by large temperature fluctuation and even out-of-control water temperature is easily generated, the accuracy of the water outlet temperature of the instant heating device is reduced, and further the water outlet effect of the instant heating device is reduced.
Therefore, the temperature predictive control device 900 of the instant heating device provided by the embodiment collects the currently detected water temperature of the instant heating device through the obtaining module 902, and collects a plurality of historical detected water temperatures of the instant heating device within a first preset time period before the current time. That is, the outlet water temperature of the heating device has a certain regularity along with the change of time, and based on this, the processing module 904 processes the collected multiple historical detected water temperatures and the current detected water temperature to determine the current actual outlet water temperature of the heating device, that is, determine the detected water temperature of the water temperature detection piece after the second preset time period at the current time (that is, the predicted outlet water temperature). Therefore, the accuracy of determining the actual outlet water temperature of the instant heating device is ensured, in the temperature prediction control process of the subsequent instant heating device, the control error caused by the work delay of each part in the instant heating device is reduced, the accuracy of the work control of the instant heating device is improved, the outlet water effect of the instant heating device is improved, and the overall performance of the instant heating device is further improved.
The detection time interval corresponding to two adjacent historical detected water temperatures is a second preset time length, the first preset time length is N times of the second preset time length, and N is a positive integer greater than or equal to 2. That is, in this embodiment, the obtaining module 902 collects the currently detected water temperature of the instant heating device and a plurality of historical detected water temperatures of the instant heating device within a first preset time period before the current time at intervals of a second preset time period.

In addition, the N is defined as a positive integer which is greater than or equal to 2, namely the first preset time period is defined to be at least twice of the second preset time period, namely the number of the historically detected water temperatures is defined to be at least two, so that the accuracy of the detected water temperature data in the historical temperature change process is ensured, and the accuracy of the predicted water temperature can be further ensured.
Further, the second preset time period is related to the delay time period of the outlet water temperature detection part of the instant heating device. Specifically, the value of the second preset time period is equal to the lag time of the detected water temperature detected by the outlet water temperature detection piece compared with the actual outlet water temperature of the instant heating device. After the lag time that the detected water temperature detected by the outlet water temperature detecting element is compared with the actual outlet water temperature of the instant heating device is obtained, the obtaining module 902 obtains the current detected water temperature of the instant heating device and a plurality of historical detected water temperatures of the instant heating device within a first preset time before the current time by taking the lag time as a time interval, and then predicts the current actual outlet water temperature of the instant heating device according to the obtained plurality of detected water temperature data by virtue of the change rule of the outlet water temperature along with time so as to eliminate the influence of the delay time of the outlet water temperature detecting element on the outlet water temperature detection.
It should be noted that the lag time between the detected water temperature detected by the outlet water temperature detector and the actual outlet water temperature of the instant heating device can be determined through a large number of experiments, and the obtained result is stored in the memory of the instant heating device in advance for later retrieval and use.
Illustratively, when a water outlet instruction input by a user is received, a lag time of a detected water temperature detected by a water outlet temperature detecting element prestored in a memorizer of the instant heating device compared with an actual water outlet temperature of the instant heating device is acquired to be n (n is more than or equal to zero) seconds, n seconds are taken as a preset time interval, a current detected water temperature of the water outlet temperature detecting element, a historical detected water temperature n seconds before the current time, a historical detected water temperature 2n seconds before the current time, a historical detected water temperature 3n seconds before the current time and the like are acquired through an acquisition module 902, and then an actual detected water temperature of the water temperature detecting element n seconds after the current time is determined through a processing module 904 according to the acquired current detected water temperature and the historical detected water temperatures by virtue of the regularity of the water outlet temperature of the instant heating device along with time, namely, the current actual outlet water temperature of the instant heating device is determined so as to eliminate the influence of the delay time of the outlet water temperature detection piece on the outlet water temperature detection.
