Problems solved by technology

[0003] The mechanical kettle starts and stops heating according to the signal of the water temperature sensor. Since there is no detection and judgment on the amount of water in the kettle, when there is no water in the kettle, the water is boiled dry, or the water is poured out by the user, the water temperature sensor will The signal directly starts the heating, causing the electric kettle to dry, which is easy to cause damage or even a fire hazard

Embodiment 1

[0051] like Figure 1-2 As shown, a method for controlling heat preservation of an electric kettle is provided. The electric kettle is provided with a water temperature sensor 2 assembled in the kettle body 1, a water quantity detection device 5, a main control board 3 and a heating assembly 4, and the water temperature sensor 2 is arranged in the kettle body. Inside, the water temperature sensor 2 transmits the detected water temperature information in the pot to the main control board 3 , and the water volume detection device 5 transmits the detected water volume information to the main control board 3 .

[0052] According to the water temperature information and water quantity information, the main control board 3 controls the heating component 4 to heat and regulate the water temperature in the kettle only when the water quantity in the kettle is greater than the anti-dry threshold.

[0053] When the user lifts the kettle body 1 and puts it back after adding water in the h...

Embodiment 2

[0063] A method for controlling the heat preservation of an electric kettle, the other features are the same as in Embodiment 1, the difference is that: image 3 As shown, the water quantity detection device 5 includes a plurality of capacitive sensors 51 mounted on different water levels and a processor connected to the plurality of capacitive sensors 51, and the plurality of capacitive sensors 51 compare the detected capacitance with each capacitive sensor 51 Compare with the initially set capacitance;

[0064] If the capacitance detected by the sensor is greater than or equal to the corresponding capacitance initially set, it is determined that there is water at the water level;

[0065] If the capacitance detected by the sensor is less than the corresponding capacitance initially set, it is determined that there is no water at the water level;

[0066] The capacitive sensors 51 at multiple water levels send the detection results to the processor, and the processor compare...

Embodiment 3

[0069] A method for controlling the heat preservation of an electric kettle, the other features are the same as in Embodiment 1, the difference is that: Figure 4 As shown, the water quantity detection device 5 includes a plurality of water level probes 52 assembled at different water level heights and a processor connected to the plurality of water level probes 52, and the plurality of water level probes 52 compare the detected conductivity with each The capacitance initially set by the water level probe 52 is compared;

[0070] If the detected conductivity is greater than or equal to the initially set conductivity, it is determined that there is water at the water level;

[0071] If the detected conductivity is lower than the initially set conductivity, it is determined that there is no water at the water level.

[0072] It should be noted that in this embodiment, the water level probe 52 is used as the detection device to detect the water level information, and at the same...

Abstract

The invention discloses a method for controlling thermal insulation after lifting of an electric kettle. A water temperature sensor, a water volume detection device, a main control board and a heating assembly are assembled in a kettle body of the electric kettle, the water temperature sensor is arranged in the kettle and transmits detected in-kettle water temperature information to the main control board, and the water volume detection device transmits detected water volume information to the main control board. By means of the added in-kettle water volume detection function, the water volume of the kettle can be detected in real time; when no water exists in the kettle or water is dried out or used up by a user, the electric heating kettle reliably enters a water shortage protection procedure, dry heating of the electric heating kettle is prevented, and damage or danger is avoided. Control of the electric kettle is more intelligent and humanized, and the use experience of the user is improved while the product reliability is improved.

Description

technical field [0001] The invention relates to the technical field of lifting kettle heat preservation, in particular to a method for controlling heat preservation of an electric kettle lifting kettle. Background technique [0002] Electric kettles are one of the most frequently used household appliances in general households. The vast majority of electric kettles use electric heating wires for heating. In order to ensure the heating speed, the general heating power is relatively high. Therefore, it is necessary to avoid dry heating of the kettle in the absence of water. Once the dry heating may cause damage to the kettle, serious even Risk of fire, electric shock. In the prior art, some electric kettles have heat preservation function. Through intermittent supplementary heating, the water in the kettle is maintained at the set temperature range. When the user lifts the kettle to pour water, put the kettle back on the kettle seat to continue to maintain Insulation state, ...
