Embodiment 1

[0057] A kind of insulation method of electric kettle, such as figure 1 As shown, the method may include S01-S102:

[0058] S101. Real-time collection of the current water temperature T in the electric kettle C ;

[0059] S02. Set the preset heat preservation point T K The upper and lower limits of the current water temperature T C The comparison standard and according to the current water temperature T C The heating signal is controlled in real time by the comparison result with the upper limit value and the lower limit value.

[0060] In the embodiment of the present invention, in order to achieve the heat preservation effect, it is necessary to judge the water temperature in time, and judge the heat preservation effect by comparing the current water temperature with the set heat preservation point. In the embodiment of the present invention, the holding point T K The upper and lower limits of the current water temperature T C The comparative standard adopts double st...

Embodiment 2

[0063] In this embodiment, on the basis of Embodiment 1, according to the current water temperature T C The scheme of controlling the heating signal in real time with the comparison result of the upper limit value and the lower limit value is introduced in detail.

[0064] Optionally, as in figure 2 , image 3 shown, according to the current water temperature T C The real-time control of the heating signal based on the comparison result with the upper limit value and the lower limit value may include S201-S202:

[0065] S201. Set the current water temperature T C Respectively with the holding point T K Compare the upper limit value with the lower limit value;

[0066] S202. When the current water temperature T C When it is less than or equal to the lower limit value, control the electric kettle to start heating; when the current water temperature T C When greater than or equal to the upper limit, control the electric kettle to stop heating.

[0067] Optionally, the up...

Embodiment 3

[0078] In this embodiment, on the basis of the second embodiment, the upper limit fluctuation value ΔT U and the lower limit fluctuation value ΔT D The value of is further limited.

[0079] Optionally, the upper limit fluctuation value ΔT U and the lower limit fluctuation value ΔT D Can include: 2-5 AD values ​​respectively.

[0080] In the embodiment of the present invention, in order to achieve the heat preservation effect, it is necessary to judge the water temperature in time, and judge the heat preservation effect by comparing the current water temperature with the set heat preservation point. And if the insulation range is set relatively large, that is, ΔT U and ΔT D If it is too large, the heat preservation accuracy will be very poor, which means that the heat preservation effect is poor; but if the ΔT U and ΔT D If the setting is small, the frequency of the heat preservation power will be high, which will increase the power consumption, but will improve the heat...

Abstract

The embodiment of the invention discloses a heat insulation method of an electric water kettle. The heat insulation method comprises the steps that the current water temperature TC of the interior ofthe electric water kettle is acquired in real time; the upper limit value and the lower limit value of the preset heat insulation point TK are taken as the comparison standards of the current water temperature TC, and a heating signal is controlled in real time according to the comparison results of the current water temperature TC with the upper limit value and the lower limit value. The heat insulation precision is improved through the heat insulation method of the electric water kettle.

Description

technical field [0001] The embodiment of the present invention relates to the control technology of a liquid heating device, in particular to a heat preservation method for an electric kettle. Background technique [0002] With the gradual improvement of people's living standards, the demand for drinking water has begun to pursue scenarios. Different scenarios require water at different temperatures, such as brewing milk, coffee, and tea. This has new requirements for the function of the electric kettle, which needs to provide accurate heat preservation at different temperatures. At present, most of the heat preservation schemes on the market use real-time temperature feedback to control heating to achieve heat preservation within a certain temperature range, but the heat preservation effect is not good because the water temperature is greatly affected by external factors and the accuracy of the temperature measurement scheme is not high. Contents of the invention [0003...
