The water level of the balance water tank is parallel to the water outlet of the instant heating pipe of the instant heating water drinking device, so that the situation that the instant heating pipe is free of water does not exist, the problems of instant heating pipe dry heating and the like cannot occur, the control is simple, and the instant heating system partially occupies a large volume. In order to miniaturize the instant heating water dispenser and be widely applied to products with various sizes, the instant heating system is minimized, namely a balance water tank of the instant heating system is eliminated, wherein the instant heating system comprises an instant heating pipe, a water inlet temperature sensor, a water outlet temperature sensor and a water pump, and the instant heating pipe temperature sensor is additionally arranged on the instant heating pipe, so that the instant heating water dispenser is miniaturized on the structure of the instant heating system and can be better applied to various products.
In the aspect of controlling the water temperature, for the instant heating system with the balance water tank, the temperature control is based on the outlet water temperature, and the temperature regulation is simpler; however, for the instant heating system without the balance water tank, if the control is still performed based on the outlet water temperature, the water temperature changes greatly under the condition of input fluctuation, so the water temperature trend needs to be judged to better control the water temperature to reach the target temperature quickly.

In this embodiment, at the time of starting the water discharge, both the lowest temperature (first water temperature) and the highest temperature (second water temperature) of the discharged water are assigned as the initial water temperature. In the whole water outlet process, the minimum temperature and the maximum temperature are updated along with the change of the real-time water temperature, namely the real-time water temperature is assigned to the minimum temperature when the real-time water temperature is smaller than the minimum temperature, and the real-time water temperature is assigned to the maximum temperature when the real-time water temperature is larger than the maximum temperature, so that the trend of the water temperature is accurately judged by using the continuous updating mode of the minimum temperature and the maximum temperature.
When it is determined that the real-time water temperature is greater than the first water temperature (the lowest temperature) and less than the second water temperature (the highest temperature), it indicates that the change curve of the real-time water temperature is a parabolic curve as shown in fig. 3a or 3b, and the real-time water temperatures at time T1, time T2, time T3, and time T4 are water temperatures between the lowest temperature and the highest temperature. And judging whether the last updated water temperature is the lowest temperature or the highest temperature, if the last updated water temperature is the lowest temperature, the real-time water temperature is in an ascending trend, and if the last updated water temperature is the highest temperature, the real-time water temperature is in a descending trend, so that the change trend of the outlet water temperature is more accurately judged.
In an embodiment of the present invention, preferably, the determining unit 708 is further configured to determine that the real-time water temperature is in a decreasing trend when the real-time water temperature is less than or equal to the first water temperature; and when the real-time water temperature is greater than or equal to the second water temperature, determining that the real-time water temperature is in an ascending trend.
In this embodiment, when the real-time water temperature is less than or equal to the minimum temperature (first water temperature), the real-time water temperature is determined to be a single drop, followed by a downward trend. When the real-time water temperature is greater than or equal to the maximum temperature (second water temperature), the real-time water temperature is determined to be in single rising, and then the real-time water temperature also has a rising trend.
