Embodiment 1

[0026] This embodiment provides a water temperature constant temperature control method, which is mainly used in the field of raising the water temperature, and can be applied to various electrical equipment for heating water such as electric kettles, electric water heaters, and water dispensers.

[0027] The control method provided in this embodiment includes the following steps:

[0028] S1. Obtain the target temperature and water injection volume;

[0029] In this step, the target temperature refers to the water temperature of the hot water that the user finally wishes to obtain. According to the different needs of users for hot water, the target temperature will also change accordingly. For example: when brewing green tea, the target temperature is suitable for selection at 80°C-90°C; when brewing Puer tea, the target temperature is suitable for selection 100°C. In this step, the amount of water injected refers to the amount of water injected into the electric kettle by ...

Embodiment 2

[0068] This embodiment provides a computer-readable storage medium, which stores a computer program for execution by an electronic device. When the program runs on the electronic device, the electronic device executes the water temperature constant provided in Embodiment 1. Control Method.

Embodiment 3

[0070] This embodiment provides an electric heating water heating device, including: a temperature acquisition module, used to acquire the real-time temperature in the electric kettle; a water injection volume acquisition module, used to acquire the water injection volume in the electric kettle; a heating module, used for The electric kettle is heated; the temperature compensation module is used to obtain the compensation temperature according to the real-time temperature, the water injection volume and the target temperature; the control module is used to stop when the sum of the compensation temperature and the real-time temperature is greater than or equal to the target temperature Heating operation.

[0071] In the electric heating water heating device provided in this embodiment, the temperature compensation module includes: a first temperature compensation module, which obtains a first temperature compensation value according to the target temperature and the water inject...

Abstract

The present invention provides a water temperature constant temperature control method and electric hot water equipment, comprising: acquiring a target temperature and water injection volume; calculating a first compensation value according to the target temperature and water injection volume; Calculating the second compensation value; acquiring the current real-time temperature; and stopping the heating operation when the sum of the first compensation value, the second compensation value and the real-time temperature is greater than or equal to the target temperature. In the present invention, the method of cutting off the power in advance and using the waste heat to slowly raise the temperature to reach the target temperature can avoid the situation that the heating method in the prior art tends to cause the temperature of the finally obtained hot water to exceed the preset temperature. At the same time, when determining the temperature to stop heating, the target temperature, the amount of water injection, and the amount of temperature increase in the sampling period are considered at the same time. It can weaken the influence of voltage, target temperature and water injection volume, so as to achieve the purpose of precise temperature setting.

Description

technical field [0001] The invention relates to the technical field of electric kettle temperature control, in particular to a method for precise temperature control of an electric kettle. Background technique [0002] Electric kettle is an indispensable electrical equipment in people's daily life. The inside of the electric kettle is provided with a resistance wire, and the water inside the electric kettle is heated by heating through the resistance wire. [0003] The electric kettle in the prior art often allows the user to directly select the final temperature of the hot water, thereby satisfying the user's demand for hot water at different temperatures. However, since electric kettles are heated by resistance wires, when the water temperature reaches the preset temperature, the control program controls the resistance wires to stop power supply, but because there is still preheating on the resistance wires, the resistance wires still heat the hot water, resulting in The...
