However, pointed NTC is easy to scratch the inside of the pot and is not easy to clean. Flat NTC is NTC wrapped in metal, which makes its heat transfer slow, resulting in a serious lag in temperature detection and inability to accurately control the temperature during heating.

For example, without departing from the scope of the embodiments of the present invention, the first set threshold may also be referred to as the second set threshold, and similarly, the second set threshold may also be referred to as the first set threshold.

[0054] Figure 1 This is a schematic diagram of the structure of an electric kettle provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the electric kettle includes a heating plate 1, a flat-top negative temperature coefficient (NTC) temperature sensor 2, and a kettle body 3.

[0055] In this embodiment of the invention, the heating plate 1 is disposed at the bottom of the kettle and is used to heat the liquid in the electric kettle. The heating plate 1 transfers heat to the flat-head NTC 2 by thermal radiation.

[0056] In this embodiment of the invention, the flat-head NTC 2 is located at the center of the heating plate 1 and extends inward into the heating plate 1. The flat-head NTC 2 is mainly used to measure the temperature of the liquid in the electric kettle.

[0057] In this embodiment of the invention, the heating plate 1 is sealed to the kettle body 3, and the kettle body 3 is a kettle-shaped container for holding liquid.

[0058] In the technical solution provided by the embodiment of the present invention, the first temperature is detected by the flat head temperature sensor of the electric kettle; if the difference between the set target temperature and the first temperature is greater than or equal to the set first threshold, the electric kettle is controlled to heat at a specified first power and the second temperature is detected; in response to the second temperature being greater than or equal to the set second threshold, the electric kettle is controlled to stop heating; when the duration of stopping heating reaches the set first duration, the overshoot temperature is calculated according to the second temperature and the detected third temperature; if the overshoot temperature is less than the set overshoot threshold, the electric kettle is controlled to heat at a specified second power and the fourth temperature is detected; in response to the fourth temperature being greater than or equal to the target temperature, heating completion is prompted, and precise temperature control can be achieved during the heating process.

[0059] Figure 2 It is a flowchart of a heating method for an electric kettle provided by an embodiment of the present invention. As Figure 2 shown, the method includes:

[0060] Step 101: Detect the first temperature through the flat head temperature sensor of the electric kettle.

[0061] Step 102: If the difference between the set target temperature and the first temperature is greater than or equal to the set first threshold, control the electric kettle to heat at a specified first power and detect the second temperature.

[0062] Step 103: In response to the second temperature being greater than or equal to the set second threshold, control the electric kettle to stop heating.

[0063] Step 104: When the duration of stopping heating reaches the set first duration, calculate the overshoot temperature according to the second temperature and the detected third temperature.

[0064] Step 105: If the overshoot temperature is less than the set overshoot threshold, control the electric kettle to heat at a specified second power and detect the fourth temperature.

[0065] Step 106: In response to the fourth temperature being greater than or equal to the target temperature, prompt heating completion.

[0066] In the technical solution provided by this invention, a first temperature is detected by a flat-top temperature sensor of an electric kettle; if the difference between the set target temperature and the first temperature is greater than or equal to a set first threshold, the electric kettle is controlled to heat at a specified first power and a second temperature is detected; in response to the second temperature being greater than or equal to the set second threshold, the electric kettle is controlled to stop heating; when the heating stop time reaches a set first time, the charging temperature is calculated based on the second temperature and the detected third temperature; if the charging temperature is less than the set charging threshold, the electric kettle is controlled to heat at a specified second power and a fourth temperature is detected; in response to the fourth temperature being greater than or equal to the target temperature, a heating completion indicator is displayed, thus achieving precise temperature control during the heating process.

[0067] Figure 3 A flowchart illustrating another heating method for an electric kettle provided in an embodiment of the present invention is shown below. Figure 3 As shown, the method includes:

[0068] Step 201: Detect the first temperature using the flat-top temperature sensor of the electric kettle.

[0069] In this embodiment of the invention, each step can be executed by the processor of the electric kettle.

[0070] In this embodiment of the invention, the flat-head temperature sensor is a flat-head NTC, which is a thermistor whose resistance decreases as the temperature rises.

[0071] In this embodiment of the invention, the current temperature of the liquid in the electric kettle is detected by a flat-head NTC.

[0072] Step 202: Determine whether the difference between the set target temperature and the first temperature is greater than or equal to the set first threshold. If yes, proceed to step 203; otherwise, proceed to step 210.

[0073] In this embodiment of the invention, a basic threshold is first measured, and a test temperature point T and a trip temperature point T1 are set. The liquid in the electric kettle is at the lowest water level mark, and the electric kettle is controlled to heat at full power. The flat-head NTC of the electric kettle detects the temperature of the liquid in the electric kettle according to a preset time period to achieve real-time detection of the liquid temperature in the electric kettle. When the flat-head NTC detects that the current temperature is greater than or equal to the trip temperature point T1, the electric kettle is controlled to stop heating. The actual temperature T2 of the liquid in the electric kettle is measured by a thermometer. The difference between the actual temperature T2 and the test temperature point T is determined as the basic threshold ΔT, that is: ΔT = T - T2. The trip temperature point T1 is set so that when the electric kettle is controlled to stop heating, the actual temperature T2 does not exceed the test temperature point T under specified conditions. The specified conditions are that the liquid in the electric kettle is within the range between the lowest water level mark and the rated water level mark, and the liquid in the electric kettle is heated at full power.

[0074] In this embodiment of the invention, if it is determined that the difference between the target temperature and the first temperature is greater than or equal to the first threshold, it indicates that the temperature difference between the target temperature and the current temperature is large, and step 203 is continued; if it is determined that the difference between the target temperature and the second temperature is less than the first threshold, it indicates that the temperature difference between the target temperature and the current temperature is small, and step 210 is continued.

[0075] In this embodiment of the invention, the first threshold can be set according to the actual situation. As an optional solution, the first threshold is twice the basic threshold, that is: 2△T.

[0076] For example: if the target temperature is set to 80 degrees Celsius (°C), the measured base threshold ΔT is 10°C, the first threshold is 2ΔT, i.e., 20°C, the detected first temperature is 50°C, and the difference between the target temperature and the first temperature is 30°C, which is greater than the first threshold, it indicates that the temperature difference between the target temperature and the current temperature is large, so continue to step 203; if the detected first temperature is 70°C, the difference between the target temperature and the first temperature is 10°C, which is less than the first threshold, it indicates that the temperature difference between the target temperature and the current temperature is small, so continue to step 210.

[0077] Step 203: Control the electric kettle to heat according to the specified first power and detect the second temperature.

[0078] In this embodiment of the invention, the first power is specified as full power, and as an optional scheme, the first power is specified as 1200 watts (W).

[0079] In this embodiment of the invention, the temperature of the liquid in the electric kettle is detected by a flat-head NTC according to a specified preset time period, so as to realize the real-time detection of the current temperature of the liquid.

[0080] Step 204: Determine whether the second temperature is greater than or equal to the set second threshold. If yes, proceed to step 205; otherwise, proceed to step 203.

[0081] In this embodiment of the invention, if it is determined that the second temperature is greater than or equal to the second threshold, it indicates that the temperature difference between the target temperature and the current temperature is small, and step 205 is continued; if it is determined that the second temperature is less than the second threshold, it indicates that the temperature difference between the target temperature and the current temperature is large, and heating needs to continue, and step 204 is continued.

[0082] In this embodiment of the invention, the second threshold can be set according to the actual situation. As an optional solution, the second threshold is the actual temperature T2 when the flat-head NTC detects that the current temperature has reached the tripping temperature point T1, that is: T2=T-△T.

[0083] For example: if the target temperature is set to 80 degrees Celsius (°C), the measured basic threshold ΔT is 15°C, the second threshold is T-ΔT, which is 65°C, and the detected second temperature is 70°C, which is greater than the second threshold, it indicates that the temperature difference between the target temperature and the current temperature is small, so continue to execute step 205; if the detected second temperature is 60°C, which is less than the second threshold, it indicates that the temperature difference between the target temperature and the current temperature is large, and heating needs to continue, so continue to execute step 203.

[0084] Step 205: Control the electric kettle to stop heating.

[0085] In this embodiment of the invention, the electric kettle is controlled to stop heating, so that the flat-head NTC with hysteresis can detect the temperature of the liquid after heating within a specified time after heating stops.

[0086] Step 206: When the heating stop time reaches the set first time, calculate the overheating temperature based on the second temperature and the detected third temperature.

[0087] In this embodiment of the invention, the first duration can be set by the system based on performance and / or implementation requirements during specific implementation. This embodiment does not limit the size of the first duration. As an optional solution, the first duration is 40 seconds.

[0088] In this embodiment of the invention, due to the inherent hysteresis of the flat-head NTC's structure, the detected temperature will rise after a period of time when heating is stopped. Therefore, when the heating is stopped for a first period of time, the current temperature of the liquid in the electric kettle is detected by the flat-head NTC, which is the third temperature; the overheating temperature is calculated by subtracting the second temperature from the third temperature.

[0089] Step 207: Determine whether the charging temperature is less than the set charging threshold. If yes, proceed to step 208; otherwise, proceed to step 215.

[0090] In this embodiment of the invention, the overheating threshold can be set by the system based on performance and / or implementation requirements during specific implementation. This embodiment does not limit the size of the overheating threshold. As an optional solution, the overheating threshold is 1 / 2 times the base threshold, i.e., ΔT / 2.

[0091] In this embodiment of the invention, if it is determined that the boiling temperature is less than the boiling temperature threshold, it is inferred that the volume of liquid in the electric kettle is greater than or equal to 1 / 2 times the rated volume of the electric kettle, i.e., large volume, and step 208 is continued; if it is determined that the boiling temperature is greater than or equal to the boiling temperature threshold, it is inferred that the volume of liquid in the electric kettle is less than 1 / 2 times the rated volume of the electric kettle, i.e., small volume, and step 215 is continued.

[0092] Step 208: Control the electric kettle to heat according to the specified second power and detect the fourth temperature.

[0093] In this embodiment of the invention, the second power is specified as 1 / 3 of the full power. As an optional option, the second power is specified as 400 watts (W).

[0094] In this embodiment of the invention, the temperature of the liquid in the electric kettle is detected by a flat-head NTC according to a specified preset time period, so as to realize the real-time detection of the current temperature of the liquid.

[0095] Step 209: Determine whether the fourth temperature is greater than or equal to the target temperature. If yes, proceed to step 220; otherwise, proceed to step 208.

[0096] In this embodiment of the invention, if the fourth temperature is determined to be greater than or equal to the target temperature, it indicates that the liquid in the electric kettle has reached the target temperature, and step 220 is executed; if the fourth temperature is determined to be less than the target temperature, it indicates that the liquid in the electric kettle has not yet reached the target temperature and needs to be heated further, and step 208 is executed.

[0097] Step 210: Control the electric kettle to heat according to the specified third power and detect the fifth temperature.

[0098] In this embodiment of the invention, the third power is specified as 1 / 3 of the full power. As an optional scheme, the third power is specified as 400 watts (W).

[0099] In this embodiment of the invention, the temperature of the liquid in the electric kettle is detected by a flat-head NTC according to a specified preset time period, so as to realize the real-time detection of the current temperature of the liquid.

[0100] Step 211: Determine whether the fifth temperature is greater than or equal to the set third threshold. If yes, proceed to step 212; otherwise, proceed to step 210.

[0101] In this embodiment of the invention, if the fifth temperature is determined to be greater than or equal to the third threshold, it indicates that the fifth temperature is close to the target temperature, and step 212 is executed; if the fifth temperature is determined to be less than the third threshold, it indicates that the temperature difference between the fifth temperature and the target temperature is large, and heating needs to continue, and step 210 is executed.

[0102] In this embodiment of the invention, the third threshold can be set according to the actual situation. As an optional solution, the third threshold is the difference between the target temperature and 5°C, i.e., T-5.

[0103] Step 212: Control the electric kettle to stop heating.

[0104] In this embodiment of the invention, the electric kettle is controlled to stop heating, so that the flat-head NTC with hysteresis can detect the temperature of the liquid after heating within a specified time after heating stops.

[0105] Step 213: When the heating stop time reaches the set second time, control the electric kettle to heat according to the specified fourth power and detect the sixth temperature.

[0106] In this embodiment of the invention, the second duration can be set by the system based on performance and / or implementation requirements during specific implementation. This embodiment does not limit the size of the second duration. As an optional solution, the second duration is 20 seconds.

[0107] In this embodiment of the invention, the fourth power is specified as 1 / 6 of the full power; as an optional scheme, the fourth power is specified as 200W. The temperature of the liquid in the electric kettle is detected by a flat-head NTC sensor at a specified preset time period to achieve real-time detection of the liquid's current temperature.

[0108] Step 214: Determine whether the sixth temperature is greater than or equal to the target temperature. If yes, proceed to step 220; otherwise, proceed to step 213.

[0109] In this embodiment of the invention, if the sixth temperature is determined to be greater than or equal to the target temperature, it indicates that the liquid in the electric kettle has reached the target temperature, and step 220 is executed; if the sixth temperature is determined to be less than the target temperature, it indicates that the liquid in the electric kettle has not yet reached the target temperature and needs to be heated further, and step 213 is executed.

[0110] Step 215: Control the electric kettle to stop heating.

[0111] In this embodiment of the invention, the electric kettle is controlled to stop heating, so that the flat-head NTC with hysteresis can detect the temperature of the liquid after heating within a specified time after heating stops.

[0112] Step 216: When the heating has stopped for the set third duration, detect the seventh temperature.

[0113] In this embodiment of the invention, the third duration can be set by the system based on performance and / or implementation requirements during specific implementation. This embodiment does not limit the size of the third duration. As an optional solution, the third duration is 20 seconds.

[0114] In this embodiment of the invention, due to the inherent hysteresis of the flat-head NTC's structure, the detected temperature will rise after a period of time when heating is stopped. Therefore, when the heating is stopped for a third period of time, the current temperature of the liquid in the electric kettle is detected by the flat-head NTC, and this current temperature is the seventh temperature.

[0115] Step 217: Determine whether the seventh temperature is greater than or equal to the target temperature. If yes, proceed to step 220; otherwise, proceed to step 218.

[0116] In this embodiment of the invention, if the seventh temperature is determined to be greater than or equal to the target temperature, it indicates that the liquid in the electric kettle has reached the target temperature, and step 220 is executed; if the seventh temperature is determined to be less than the target temperature, it indicates that the liquid in the electric kettle has not yet reached the target temperature and needs to be heated further, and step 218 is executed.

[0117] Step 218: Control the electric kettle to heat according to the set fifth power and detect the eighth temperature.

[0118] In this embodiment of the invention, the fifth power is specified as 1 / 6 of the full power. As an optional solution, the sixth power is specified as 200W. The temperature of the liquid in the electric kettle is detected by a flat-head NTC sensor according to a specified preset time period to achieve real-time detection of the current liquid temperature.

[0119] Step 219: Determine whether the eighth temperature is greater than or equal to the target temperature. If yes, proceed to step 220; otherwise, proceed to step 218.

[0120] In this embodiment of the invention, if the eighth temperature is determined to be greater than or equal to the target temperature, it indicates that the liquid in the electric kettle has reached the target temperature, and step 220 is executed; if the eighth temperature is determined to be less than the target temperature, it indicates that the liquid in the electric kettle has not yet reached the target temperature and needs to be heated further, and step 218 is executed.

[0121] Step 220: Heating complete.

[0122] In this embodiment of the invention, if it is determined that the temperature of the liquid in the electric kettle has reached the target temperature, the user is notified that heating is complete. The kettle's buzzer can be set to sound to notify the user that heating is complete, effectively improving the user experience. Other methods can also be used to notify the user that heating is complete; this embodiment of the invention does not limit the specific methods used.

[0123] In the heating method of the electric kettle provided in this embodiment of the invention, a first temperature is detected by the flat-top temperature sensor of the electric kettle; if the difference between the set target temperature and the first temperature is greater than or equal to a set first threshold, the electric kettle is controlled to heat according to a specified first power and a second temperature is detected; in response to the second temperature being greater than or equal to the set second threshold, the electric kettle is controlled to stop heating; when the heating stop time reaches a set first time, the charging temperature is calculated based on the second temperature and the detected third temperature; if the charging temperature is less than the set charging threshold, the electric kettle is controlled to heat according to a specified second power and a fourth temperature is detected; in response to the fourth temperature being greater than or equal to the target temperature, a heating completion is indicated, thus achieving precise temperature control during the heating process.
