Problems solved by technology

[0002] In the related technology, when controlling the operation of the instant heating device to obtain the outlet water at the target temperature, due to the influence of multiple factors such as the response speed of the water pump, the change time of the water temperature, and the response speed of the outlet water temperature detection device, the actual outlet water temperature of the instant heating device and the detection of the outlet water temperature There will be a certain delay error between the outlet water temperature detected by the device
In this way, it is difficult for the temperature control system of the instant heating device to accurately control the actual situation of the outlet water temperature, which reduces the accuracy of the working control of the instant heating device, and thus is prone to overshoot, large temperature fluctuations, and even water temperature out of control leading to boiling and vaporization. The accuracy of the water outlet temperature of the instant heating device, which in turn reduces the water outlet effect of the instant heating device

Abstract

The invention provides an instant heating device, a temperature prediction control method and device thereof and a water treatment device. The temperature prediction control method of the instant heating device comprises the steps that multiple historical detection water outlet temperatures within a first preset duration before the current time are obtained; the current detected water outlet temperature at the current time is obtained; and according to the current detected outlet water temperature and the multiple historical detected outlet water temperatures, the predicted outlet water temperature after the second preset duration after the current time is determined. According to the temperature prediction control method of the instant heating device, the current detected water outlet temperature and the multiple historical detected water outlet temperatures of the instant heating device are collected, and the actual water outlet temperature after the second preset duration is obtained according to the collected multiple temperatures. Thus, the accuracy of determining the actual water outlet temperature of the instant heating device is guaranteed, in the subsequent temperature prediction control process of the instant heating device, control errors caused by work delay are reduced, the work control accuracy of the instant heating device is improved, and therefore the water outlet effect of the instant heating device is improved.
