Embodiment

[0023] A water heater constant temperature control method of this embodiment, such as figure 1 As shown, it includes the following steps: A1: Detect the outlet water temperature, and compare the outlet water temperature with the set temperature;

[0024] A2: If the outlet water temperature is equal to the set temperature, perform step A1; if the outlet water temperature is not equal to the set temperature, perform step A3; the outlet water temperature is the water temperature output to the user after heating by the water heater. When they are equal, it is necessary to repeatedly compare the outlet water temperature with the set temperature. Since the water temperature control is a continuous process, it is necessary to continuously monitor the water temperature. Some subtle changes in the inlet water environment may cause changes in the outlet water temperature. For example, when the temperature is low in winter, since some of the water pipes are indoors and part of the water ...

Abstract

The invention discloses a constant temperature control method for a water heater. In order to solve the problems that in the prior art, the water temperature adjusting speed is low, the adjusting time is long, and a user feels uncomfortable, a water amount server is adopted for adjusting the water amount, the optimal water amount is calculated, an optimal heating curve is generated, and when the outlet water temperature is not equal to the set temperature, the optimal water amount is obtained through calculation; the water outlet amount is adjusted to the optimal water amount so as to keep the water temperature constant, and after the optimal water amount is calculated for the first time, besides environment condition changes, the water amount is kept stable at the optimal water amount, it is guaranteed that the water outlet temperature is constant, the influence of the hysteresis effect is reduced, and the temperature adjusting precision and the temperature adjusting speed are improved; through temperature adjustment closed-loop detection, the water amount is readjusted in time when the environment water temperature and the water amount change, and real constant-temperature control is achieved.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a constant temperature control method for a water heater. Background technique [0002] At present, most of the water volume servers on the market are controlled at the maximum power when the water outlet temperature cannot reach the shrinkage process, and the water volume server can only be maintained at the maximum power operation. , did not achieve the functions of rapid heating and water temperature maintenance; in order to improve the problem of heat exchanger heating delay, due to the current constant temperature control, the heater power will only be adjusted when the temperature changes, and then the heat energy will be converted through the heat exchanger. , resulting in a heating delay effect, resulting in unstable constant temperature; some thermostatically controlled water heaters, when the power of the electric water heater is sufficient to provide the required...
