[0096] Further, based on the first embodiment of the heating control method for a liquid heating container of the present invention, in the second embodiment of the heating control method, judging whether the second change rate changes includes:

[0097] When the temperature of the liquid inside the liquid heating container is greater than the preset temperature, it is judged whether the second rate of change changes.

[0098] That is, on the basis of the first embodiment, in addition to obtaining the two capacitances sensed by the capacitive sensing sheet 10 when the liquid heating container is heated, the temperature of the liquid inside the kettle body 1 during heating is also obtained simultaneously. In this example, if figure 1 As shown, in order to obtain the temperature signal, the health pot can further include a temperature sensor 8 arranged at the bottom of the body 1 to detect the temperature of the liquid such as water inside the body 1, and the temperature signal ...

[0099] Further, based on the first embodiment of the heating control method for the liquid heating container of the present invention, in the third embodiment of the heating control method, it also includes:

[0100] When it is determined that the second rate of change has changed, the heating power to the liquid heating container is reduced.

[0101] From the analysis in the first embodiment, it can be seen that before the second change rate Vc2 changes, the liquid heating container has not yet produced foam or the foam has not risen, so at this time, the power to the liquid heating container can be increased, that is, with a constant maximum The power is used to heat the liquid heating container; and when the second change rate Vc2 changes, the surface foam starts to rise. If the original high power is maintained at this time, the foam will rise too fast and there is a risk of overflow. Therefore, it is necessary to reduce the power at this time , For example, intermittent h...

Abstract

The invention relates to the field of household appliance control, and discloses a heating control method, a device, a medium and a liquid heating container. According to the heating control method, when the liquid heating container is heated, a first capacitance of an upper capacitance sensing sheet and a second capacitance of a lower capacitance sensing sheet are obtained; when both the first capacitance and the second capacitance are changed, a first change rate of the first capacitance and a second change rate of the second capacitance are determined, then, under the condition that the first change rate and the second change rate are kept stable within a preset time period, it is determined whether the second change rate is changed, when it is determined that the second change rate ischanged, it is determined whether the first change rate is changed, and heating of the liquid heating container is stopped when it is determined the first change rate is changed. Therefore, accurate detection and control of overflow of the liquid heating container are realized, the problem of fault accidents caused by foam overflow generated during heating of the liquid heating container is effectively prevented, and the user experience is also improved.

Description

technical field [0001] The present invention relates to the technical field of home appliance control, in particular to a heating control method, device, medium and liquid heating container. Background technique [0002] Along with the use of the home appliance product of liquid heating container more and more widely, except the electric kettle of boiling water, also produced the liquid heating container of other functions such as the health pot of cooking health-preserving food material. [0003] The above-mentioned liquid heating container is prone to foam during use, especially for health pots, which is easy to cause overflow, stain the countertop, and even cause the liquid to seep into the circuit board to cause a short circuit, resulting in fire and contact accidents, and poor user experience. . Therefore, the control of anti-overflow is particularly important. Present product generally adopts intermittent heating control to realize, and when intermittent heating caus...
