Embodiment 1

[0035] Such as Figure 1-Figure 3 As shown, the present embodiment provides a water heater control method, which controls the heating temperature of the hot water in the inner tank of the water heater through the bathing time set by the user. While setting the bathing time, it is also necessary to set the bathing water temperature and the bathing water flow rate when the user takes a bath. value. By setting the above parameters and according to the law of energy conservation, calculate the minimum temperature of the hot water in the inner tank of the water heater that needs to be heated, so as to control the heating temperature of the hot water in the inner tank of the water heater.

[0036] When the user uses the water heater to take a bath, the water heater heats the water in the inner tank, and mixes it with cold water until the bath water at an appropriate bathing temperature is used by the user. The user can set the bathing time according to the needs, and control the t...

Embodiment 2

[0064] This embodiment provides a water heater, and the control method in Embodiment 1 is applied. The user can set the bathing time according to the needs, and control the temperature of the hot water in the inner tank of the water heater according to the set bathing time, that is, realize heating on demand, and make the hot water and cold water in the water heater mix to a suitable bathing temperature, then you can set it up In the case of a certain bathing water flow rate or the user's habitual bathing water flow rate, the demand for the set bathing time can be met, that is, the use demand of the user can be met with the minimum energy consumption.

Abstract

The invention discloses a control method of a water heater, and the water heater. The control method of the water heater comprises the steps that the heating temperature of hot water in a water heaterliner is controlled through the bathing time set by a user; and through the set bathing time, according to the energy conservation law, the minimum temperature of the hot water, needing to be heated,in the water heater liner is calculated to guarantee that bathing water mixed with the hot water in the liner and cold water meets the needs of the bathing time of the user, thus on-demand heating isachieved, energy consumption is reduced, and the purpose of energy saving is achieved.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a water heater control method and the water heater. Background technique [0002] As users' requirements for bathing quality and experience increase, on-demand heating and accurate prediction of remaining hot water or bathing time allow users to control bathing progress in real time, and can respond to hot water waste and insufficient bathing water in a timely manner, becoming a water heater An important direction of intelligence. [0003] Existing water heaters generally can only predict the remaining bathing time, and cannot be heated according to the bathing time set by the user, so the energy-saving effect is poor; the accuracy of the prediction method for the remaining bathing time is low, and more sensors need to be installed in the water heater Increase the manufacturing and maintenance cost of water heater, also can affect the reliability of its use simultaneously....
