[0002] An electro-ceramic stove is a device that uses electro-thermal infrared radiation for heating. The electro-ceramic stove can heat various cookware (such as iron, aluminum, tile, ceramic, etc. flat-bottomed cookware), and is deeply loved by users.

[0003] When the electro-ceramic stove is in heating operation, the temperature of the stove top can reach above 500 degrees Celsius. After the electro-ceramic stove is powered off, the residual temperature of the stove top is relatively high, and the time required for the residual temperature to drop to a safe temperature is relatively long. Therefore, if the user touches the stove top of the electro-ceramic stove without knowing the temperature of the stove top, it may cause the user to be scalded, resulting in low safety in using the electro-ceramic stove.

When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0042] In the related art, after the induction cooker is powered off, the remaining temperature on the stove top is relatively high, and the time required for the remaining temperature to drop to a safe temperature is relatively long. Therefore, when the user does not know the temperature of the stove top, the user may touch the stove top of the induction cooker, resulting in the user being scalded, so that the use safety of the induction cooker is relatively low.

[0043] In the present application, in order to improve the use safety of the induction cooker, the inventor designs a heating device, including: a stove top assembly, a temperature measurement assembly, a weighing assembly, and an alarm assembly. After the induction cooker is powered off, the temperature of the stove top assembly is measured by the temperature measurement assembly, the weight of the heating device is measured by the weighing assembly, and when the temperature and weight meet certain conditions, an alarm prompt is given through the alarm assembly, so as to prevent the user from touching the high-temperature area of the heating device and prevent the user from being scalded, thereby improving the use safety of the heating device.

[0044] The heating device provided by the present application will be described below in conjunction with specific embodiments. These several specific embodiments of the heating device can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0045] Figure 1 Structural schematic of the heating device provided by the embodiment of the present application Figure 1 . As Figure 1 shown, the heating device 10 includes: a housing assembly 11, a stove top assembly 12, a temperature measuring assembly 13, a weighing assembly 14, an alarm assembly, and a control board assembly 16.

[0046] The housing assembly 11 includes a housing 111 and a cover plate 112. The housing 111 and the cover plate 112 enclose a receiving cavity.

[0047] The stove top assembly 12 is located inside the receiving cavity and is spaced apart from the cover plate 112.

[0048] The temperature measuring assembly 13 is located inside the receiving cavity. The temperature measuring assembly 13 has a temperature sensor, and a part of the temperature sensor extends into the inside of the stove top assembly 12. The temperature measuring assembly 13 is configured to measure the temperature of the stove top assembly 12.

[0049] The weighing assembly 14 is located at the bottom of the housing 111. The weighing assembly 14 is configured to measure the weight of the heating device 10.

[0054] The control board assembly 16 is located inside the receiving cavity. The control board assembly 16 is respectively connected to the stove top assembly 12, the temperature measuring assembly 13, the weighing assembly 14, and the alarm assembly. The control board assembly 16 is configured to control the alarm assembly to give an alarm prompt according to the temperature and the weight.

[0055] When the control board assembly 16 is connected to the alarm assembly, the control board assembly 16 is connected to the light strip assembly 15. The control board assembly 16 is configured to control the light strip assembly 15 to give an alarm prompt according to temperature and weight.

[0056] At present, the related art provides a safety anti-scald induction cooker, which includes: two infrared temperature sensors and an LED warning light ring. The two infrared temperature sensors are vertically arranged at the upper corner positions on the upper surface of the induction cooker body. The infrared emission direction of the infrared temperature sensor can shine into the interior of the LED warning light ring, causing the LED warning light ring to emit light. In the above related art, the infrared temperature sensors are vertically arranged at the upper corner positions on the upper surface of the induction cooker body, so that the distance between the infrared temperature sensors and the stove surface is relatively far, and the temperature of the stove surface cannot be accurately detected. In this application, the heating device 10 includes a temperature measurement component 13, and the temperature measurement component 13 has a temperature sensor. Part of the temperature sensor extends into the interior of the stove top assembly 12. Therefore, the distance between the temperature sensor and the stove surface is relatively close, and the temperature of the stove surface can be detected more accurately.

[0057] In addition, the heating device 10 provided in the embodiment of the present application includes an alarm assembly and a weighing assembly 14.

[0058] Optionally, the light strip assembly 15 includes a plurality of light strips sleeved from the inside to the outside in sequence.

[0063] Optionally, when the preset threshold is greater than 0, the light-transmitting area may be a plurality of light-transmitting strips, and the light-transmitting strips and the light strips are arranged in one-to-one correspondence. Optionally, for each light-transmitting strip, the width of the light-transmitting strip is equal to the width of the light strip corresponding to the light-transmitting strip.

[0064] Among the plurality of light-transmitting strips, the distance between two adjacent light-transmitting strips may also be equal to the preset threshold.

[0065] When the light band gives an alarm prompt, the user can view the alarm prompt through the light-transmitting band corresponding to the light band.

[0066] Optionally, the multiple light bands include a first light band, and the first light band is disposed around the side wall of the stove top assembly 12.

[0067] It should be noted that the first light band is disposed around the side wall of the stove top assembly 12. When the first light band gives an alarm prompt, it reminds the user of the heating area (i.e., the high-temperature area) corresponding to the stove top assembly 12 on the cover plate 112, preventing the user from touching the high-temperature area and improving the use safety of the heating device.

[0068] Optionally, the light band assembly 15 may also include only the first light band.

[0069] Optionally, when the light band assembly 15 includes only the first light band, the light-transmitting area may include one light-transmitting band, as Figure 3 shown.

The weight of the heating device 10 is measured by the weighing assembly 14, the temperature of the stove top assembly 12 is measured by the temperature measuring assembly 13, and the control board assembly 16 controls the alarm assembly (such as the light band assembly 15) to give an alarm prompt according to the temperature and the weight, so as to prevent the user from touching the high-temperature area of the heating device 10 and prevent the remaining temperature of the heating device 10 from scalding the user, thereby improving the use safety of the heating device 10.

[0077] Figure 2 It is a schematic diagram of a light-transmitting area provided by an embodiment of this application. AsFigure 2 As shown, the cover plate 112 has a light-transmitting area. The light-transmitting area has a plurality of light-transmitting bands. The plurality of light-transmitting bands are arranged at intervals. It should be noted that Figure 2 the following takes the plurality of light-transmitting bands including the light-transmitting band 1121 and the light-transmitting band 1122 as an example for illustration.

[0078] Figure 3 This is a schematic diagram of another light-transmitting area provided by an embodiment of the present application. As Figure 3 shown, the cover plate 112 has a light-transmitting area. The light-transmitting area includes a light-transmitting band 1123.

[0079] Based on the above embodiments, the present application further provides a control method for a heating device. The following will describe the control method provided by the present application in combination with specific embodiments. The following specific embodiments of the control method can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following will describe the embodiments of the present application with reference to the drawings.

[0080] Figure 4 This is a schematic flow of the control method provided by an embodiment of the present application Figure 1 As Figure 4 shown, the method includes:

[0081] S401. When it is determined that the heating device is in a power-off state, obtain the first current temperature of the furnace plate assembly through the temperature measurement component; the temperature measurement component and the furnace plate assembly are arranged in the heating device.

[0082] Specifically, the execution subject of the control method provided by the present application is the control board assembly in the heating device, and the control board assembly is implemented through the combination of software and hardware.

[0083] For the positions of the temperature measurement component and the furnace plate assembly in the heating device, please refer to Figure 1 the embodiment.

[0084] Specifically, obtain the first current temperature of the furnace plate assembly through the temperature sensor in the temperature measurement component.

[0085] S402. Determine whether the first current temperature is greater than a preset temperature threshold.

[0086] Optionally, the preset temperature threshold can be 60 °C, 70 °C, etc. The specific value of the preset temperature threshold is not limited herein.

[0087] S403. If the first current temperature is greater than the preset temperature threshold, obtain the first current weight of the heating device through the weighing component, and when it is determined that the first current weight meets the preset condition, give an alarm prompt through the alarm component.

[0088] Among them, the weighing component and the alarm component are arranged in the heating device.

[0089] Optionally, the alarm prompt can be a constant light, or a flash, or a voice prompt, etc. performed by the alarm component within a preset alarm duration.

[0090] Optionally, when the alarm component includes a light strip component, the alarm prompt can be performed in the following three ways.

[0091] Method 11: When the light strip component includes multiple light strips, the alarm prompt is performed through the multiple light strips.

[0092] Method 12: When the light strip component includes multiple light strips, according to the first current temperature, determine the first quantity; the first quantity indicates the number of light strips for alarm prompt among the multiple light strips included in the light strip component; the alarm prompt is performed through the first quantity of light strips among the multiple light strips.

[0093] Specifically, according to the corresponding relationship, determine the preset temperature range where the first current temperature is located; determine the preset quantity corresponding to the preset temperature range of the first current temperature as the first quantity. Among them, the corresponding relationship includes multiple preset temperature ranges and the preset quantity corresponding to each preset temperature range.

[0094] Method 13: When the light strip component includes the first light strip, the alarm prompt is performed through the first light strip, and the first light strip is arranged around the side wall of the cooking plate component 12.

[0095] In Figure 4 In the control method of the heating device provided in the embodiment, after determining that the heating device is in a power-off state, if the first current temperature of the cooking plate component is greater than the preset temperature threshold and the first current weight of the heating device meets the preset condition, an alarm prompt is given through the alarm prompt, which can timely remind the user that the residual temperature of the cover plate of the heating device is relatively high, prevent the user from being scalded, and improve the use safety of the heating device.

[0096] On the basis of the above embodiment, the control method provided in the present application will be described in detail below in combination with Figure 5 ,.

[0097] Figure 5 is a schematic flow chart of the control method provided in the embodiment of the present application Figure 2 . As Figure 5 shown, the method includes:

[0098] S501. Obtain the working voltage of the heating device.

[0099] Specifically, the working voltage (i.e., the chip working voltage) is the working voltage of the control board component.

[0100] Optionally, a voltage detection component can be provided in the heating device, and the working voltage of the heating device is obtained through the voltage detection component.

[0101] S502. Determine whether the working voltage is less than the preset power-off voltage threshold.

[0102] S503. If the working voltage is less than the preset power-off voltage threshold, determine that the heating device is in a power-off state.

[0103] S504. Use the power provided by the backup power supply component in the heating device to obtain the first current temperature of the stove top component through the temperature measurement component.

[0104] It should be noted that in this application, the control board component uses the backup power supply component (or the mains power supply component) to obtain the current temperature of the stove top component through the temperature measurement component in real time.

[0105] S505. Determine whether the first current temperature is greater than the preset temperature threshold.

[0106] If not, execute S506; otherwise, execute S507 - S512.

[0107] S506. Control the heating device to be in a standby state.

[0108] Optionally, the heating device in the standby state receives a start instruction input by the user through the operation area provided on the cover plate to control the heating device to start working.

[0109] After the heating device starts working, the current temperature of the above-mentioned stove top component and the current weight of the heating device can be collected in real time.

[0110] Optionally, after the heating device starts working, S501 - S512 can be executed.

[0111] S507. Obtain the first current weight of the heating device through the weighing component.

[0112] It should be noted that in this application, the control board component uses the backup power supply component (or the mains power supply component) to obtain the current weight of the heating device through the weighing component in real time.

[0113] S508. Obtain the second current weight stored in advance.

[0114] The second current weight is the weight of the heating device obtained by the weighing component at the previous moment of the first current weight.

[0115] S509. Determine whether the difference between the first current weight and the second current weight is greater than the preset weight threshold.

[0116] If so, execute S510; otherwise, execute S512.

[0117] S510. Give an alarm prompt through the alarm component and record the alarm duration.

[0118] The alarm duration is the duration of the alarm prompt.

[0119] S511. Determine whether the alarm duration is greater than the preset alarm duration.

[0120] If so, execute S512; otherwise, execute S507.

[0121] Optionally, the preset alarm duration can be 5 seconds, 6 seconds, etc.

[0122] S512. Control the alarm component to stop the alarm prompt and repeat the execution of S501 - S511 (or repeat the execution of S504 - S511).

[0123] Specifically, when it is detected that the alarm component gives an alarm prompt, control the alarm component to stop the alarm prompt.

[0124] It should be noted that during the execution of S503 - S511 by the above control board component, the required power comes from the backup power supply component in the heating device.

[0125] In Figure 5 In the control method of the heating device provided in the embodiment, after it is determined that the heating device is in a power-off state, when the first current temperature is greater than the preset temperature threshold and the difference between the first current weight and the second current weight is greater than the preset weight threshold, an alarm prompt is given through the alarm component, which can timely remind the user that the residual temperature of the cover plate of the heating device is relatively high, prevent the user from being scalded, and improve the use safety of the heating device.

[0126] In addition, during the repeated execution of S501 - S512, it can be realized that after it is determined that the heating device is in a power-off state, it can repeatedly judge whether the first current temperature is greater than the preset temperature threshold until the current temperature of the furnace disc component is less than or equal to the preset temperature threshold, and then control the heating device to be in a standby state, so that the alarm component stops the alarm prompt, avoiding the user touching the furnace surface when the current temperature of the furnace disc component is greater than the preset temperature threshold, resulting in the user being scalded, and improving the user's use safety.

[0127] Furthermore, in the present application, after the first current temperature is greater than the preset temperature threshold, when the difference between the first current weight and the second current weight is greater than the preset weight threshold, an alarm prompt is given through the alarm component, which can save the electric energy of the backup power supply component and ensure that there is sufficient power to ensure that the alarm component gives an alarm prompt before the current temperature of the furnace disc component drops to the preset temperature threshold, thereby improving the user's use safety.

[0128] Based on the above embodiments, the following combines Figure 6An embodiment will describe the control method when the working voltage is not less than the preset power-off voltage threshold.

[0129] Figure 6 The flowchart of the control method provided by the embodiment of the present application Figure 3 . On the basis of the above Figure 5 , as Figure 6 shown, the method further includes:

[0130] S601. If the working voltage is not less than the preset power-off voltage threshold, it is determined that the heating device is in a non-power-off state.

[0131] S602. Using the power provided by the mains power supply component in the heating device, the second current temperature of the stove top component is obtained through the temperature measuring component.

[0132] S603. Determine whether the second current temperature is greater than the preset temperature threshold.

[0133] If so, execute S604, otherwise execute S605.

[0134] S604. When it is detected that no alarm prompt is made through the alarm component, an alarm prompt is made through the alarm component.

[0135] Optionally, the method of making an alarm prompt through the alarm component can adopt any one of the above methods 11, 12, and 13.

[0136] Optionally, S604 may specifically include: S6041 obtaining the first current weight of the heating device through the weighing component; S6042 obtaining the second current weight stored in advance; S6043 determining whether the difference between the first current weight and the second current weight is greater than the preset weight threshold; S6045 if the difference between the first current weight and the second current weight is greater than the preset weight threshold, when it is detected that no alarm prompt is made through the alarm component, an alarm prompt is made through the alarm component.

[0137] Optionally, the first current weight may be greater than or less than the second current weight.

[0138] For example, when the first current weight is greater than the second current weight and greater than the preset weight threshold, the weight of the heating device decreases, indicating that the cookware on the heating device has been taken away. Since the bottom of the pot was close to the heating area before being taken away, and this heating area is the hottest area of the whole machine, it is necessary to alarm and prompt the user to avoid touching the high-temperature area when lifting the pot.

[0139] For example, when the first current weight is less than the second current weight and greater than the preset weight threshold, the weight of the heating device increases, indicating that there is an action of placing a pot or pressing the whole machine by hand (especially when the area where the whole machine is pressed by hand is not determined).
