[0054] A delicious dish not only needs superb culinary skills, but also needs precise control of temperature, but it is not easy to accurately obtain the temperature of a cooking utensil.

[0055] Currently, the cooking temperature of a cooking utensil is mainly measured by using a contact type NTC, but this method is not only difficult to realize in structure, but also slow to obtain the temperature, so it is improved, that is, a non-contact temperature measuring device is used to measure the cooking temperature of a cooking utensil.

[0056] However, the surface thermal emissivity of different material cooking utensils is not equal, resulting in low accuracy and poor reliability of the measured cooking temperature of the cooking utensil.

[0057] To address the aforementioned deficiencies, this application provides a method for calibrating temperature. When the object to be measured is in operation, the method acquires the temperature to be calibrated corresponding to the object. Based on the thermal emissivity of the object and the temperature to be calibrated, a target temperature is calculated for the object. The target temperature is then used as the actual temperature of the object. When using a non-contact temperature measuring device to measure the cooking temperature of a cooking appliance, although the materials of the cooking appliances may differ, the actual temperature is obtained by calibrating the measured cooking temperature based on the thermal emissivity. Using this actual temperature as the final cooking temperature results in a high accuracy and reliability of the final output cooking temperature. This method is highly user-friendly and practical.

[0058] The temperature calibration method provided in this application is mainly applicable to cooking utensils or cups. The application scenarios of this method are as follows: Figures 1-3 As shown, the specific process is as follows:

[0059] The first step is to obtain the boiling point temperature of the water when the cooking appliance is boiling water, under the current atmospheric pressure.

[0060] In this step, firstly, as follows Figure 1 The cooking appliance shown in Figure (A) is filled with water, but not necessarily completely; next, the appliance is placed on a gas stove, induction cooker, or fireplace to boil the water; then, the current atmospheric pressure is obtained using a pressure measuring device, which can be installed on a stove such as... Figure 1 The calibration temperature device shown in Figure (B) can also exist independently of the calibration temperature device; then, the boiling point temperature corresponding to the current atmospheric pressure is looked up through the pressure boiling point mapping table.

[0061] The second step is to obtain the radiant temperature of the cooking utensils using a non-contact temperature measuring device.

[0062] In this step, first press as follows Figure 1 The on / off switch of the calibration temperature device shown in Figure (C) is as follows: Figure 1 The non-contact temperature measuring device in the calibration temperature apparatus shown in Figure (B) will automatically measure, for example... Figure 1 The cooking appliance in Figure (A) radiates heat; then, as shown in Figure (A), Figure 1 The calibration temperature device shown in Figure (C) displays the radiation temperature measured by the non-contact temperature measuring device on the screen.

[0063] The third step is to calculate the thermal emissivity of the cooking appliance based on the boiling point temperature and radiation temperature.

[0064] In this step, press as shown Figure 1calculates and saves the thermal emissivity key, and the calibration temperature device automatically calculates the thermal emissivity based on the boiling point temperature of the boiling water and the radiation temperature of the cooking utensil measured in the above steps, and automatically saves the calculated thermal emissivity in the memory in the calibration temperature device for calling in the subsequent steps.

[0065] Fourthly, when the cooking utensil is in the working state, the corresponding to-be-calibrated temperature of the cooking utensil is obtained.

[0066] In this step, first, the cooking utensil as shown in the (A) of the FIG. 1 is placed on a fire tool such as a gas stove, an electromagnetic oven or a fire stove for cooking, at this time, the cooking utensil will radiate a certain temperature, which is not necessarily the real temperature of the cooking utensil, so it is taken as the to-be-calibrated temperature first, and then it is calibrated in the subsequent steps to calculate the actual temperature of the cooking utensil; secondly, the non-contact temperature measuring device of the calibration temperature device as shown in the (B) of the FIG. 1 automatically measures the to-be-calibrated temperature of the cooking utensil; then, the calibration temperature device as shown in the (C) of the FIG. 1 displays the to-be-calibrated temperature of the cooking utensil on the display screen. Figure 2 Figure 2 Figure 2

[0067] Fifthly, the target temperature of the cooking utensil is calculated according to the thermal emissivity corresponding to the cooking utensil and the to-be-calibrated temperature.

[0068] In this step, first, the calculation target temperature key of the calibration temperature device as shown in the (C) of the FIG. 1 is pressed, the calibration temperature device automatically calculates the target temperature of the cooking utensil as shown in the (A) of the FIG. 1; secondly, the calibration temperature device displays the target temperature of the cooking utensil on the display screen. Figure 2 Figure 2

[0069] Sixthly, the target temperature calculated in the above step is taken as the actual temperature of the cooking utensil.

[0070] The calibration temperature device in the above steps is a desktop device, which can be directly placed in a suitable position beside the cooking utensil, the non-contact temperature measuring device is aimed at the periphery of the cooking utensil, the to-be-calibrated temperature of the cooking utensil is measured, the thermal emissivity is calculated, and finally the target temperature of the cooking utensil is calculated, which is the actual temperature of the cooking utensil.

[0071] The calibration temperature device can also be a handheld device as shown in the (C) of the FIG. 1. Figure 3 ​​​​​The hand-held device shown in (B) of FIG. 1 is used by directly holding the device in hand, aiming the non-contact temperature measuring device of the device at the periphery of the cooking appliance, and then pressing the corresponding control key to measure the temperature to be calibrated of the cooking appliance, calculate the thermal emissivity, and finally calculate the target temperature of the cooking appliance, which is the actual temperature of the cooking appliance.

[0072] The calibration temperature device can also be a hanging device as shown in (D) of FIG. 1, which is used by directly hanging the device on the wall, aiming the non-contact temperature measuring device of the device at the periphery of the cooking appliance, and then pressing the corresponding control key to measure the temperature to be calibrated of the cooking appliance, calculate the thermal emissivity, and finally calculate the target temperature of the cooking appliance, which is the actual temperature of the cooking appliance. Figure 3 The calibration temperature device can also be a hanging device as shown in (D) of FIG. 1, which is used by directly hanging the device on the wall, aiming the non-contact temperature measuring device of the device at the periphery of the cooking appliance, and then pressing the corresponding control key to measure the temperature to be calibrated of the cooking appliance, calculate the thermal emissivity, and finally calculate the target temperature of the cooking appliance, which is the actual temperature of the cooking appliance.

[0073] The above calibration temperature device can also be used to measure and calibrate the temperature to be calibrated of a cup, and finally obtain the actual temperature of the cup, which is substantially the same as the process of calculating the target temperature of the cooking appliance, and will not be described here.

[0074] The implementation process of the calibration temperature method will be described below through specific embodiments.

[0075] Please refer to Figure 4 , Figure 4 is the implementation flowchart of the calibration temperature method provided by the embodiments of the present application. As shown in Figure 4 , the method can include the following steps:

[0076] S401, when the object to be measured is in a working state, obtaining the temperature to be calibrated corresponding to the object to be measured.

[0077] In some embodiments, the object to be measured can be a cooking appliance or a cup, etc. The object to be measured in a working state means that the object to be measured is being used to realize its functions.

[0078] The temperature to be calibrated of the object to be measured is the radiation temperature of the object to be measured in the working state, which is not necessarily the actual temperature of the object to be measured, so calibration is needed. The temperature to be calibrated of the object to be measured can be obtained by a non-contact temperature measuring device.

[0079] For example, the object to be measured is a cooking utensil. When the cooking utensil is used for cooking, it is placed on a gas stove, an induction cooker or a fire stove, and the fire tool conducts heat to the cooking utensil. The cooking utensil radiates a certain temperature, which can be measured by a non-contact infrared temperature sensor. However, due to the different materials and thermal radiation rates of different cooking utensils, the radiation temperature is not necessarily the actual temperature of the cooking utensil. Therefore, the actual temperature of the cooking utensil needs to be calculated by using the thermal radiation rate of the cooking utensil. Therefore, the radiation temperature of the cooking utensil in the working state is taken as the temperature to be calibrated, and then the temperature to be calibrated is calibrated. The temperature to be calibrated of the cooking utensil can be measured by a non-contact infrared temperature sensor. For example, the temperature to be calibrated of the cooking utensil is 70℃.

[0080] In S402, a target temperature of the object to be measured is calculated according to the thermal radiation rate corresponding to the object to be measured and the temperature to be calibrated.

[0081] In some embodiments, the thermal radiation rate corresponding to the object to be measured can be measured and calculated by a merchant in advance according to different materials of the object to be measured and stored in the calibration temperature device provided in the embodiments of the present application. Alternatively, the thermal radiation rate can be calculated by a user according to the material of the object to be measured and by using a thermal radiation rate formula when the user actually uses the calibration temperature device. The calculated target temperature is the actual temperature of the object to be measured.

[0082] For example, the merchant can calculate the corresponding thermal radiation rate according to different materials of the cooking utensil, and store the calculated thermal radiation rate in the calibration temperature device. When the user uses the calibration temperature device, the user can directly call the thermal radiation rate measured in advance by the merchant. If the merchant does not measure the thermal radiation rate of the cooking utensil of any material in advance, the user can calculate the thermal radiation rate corresponding to the cooking utensil according to the material of the cooking utensil owned by the user and by using a thermal radiation rate calculation formula. If the merchant only measures the thermal radiation rate of the cooking utensil of some materials, and the material of the cooking utensil owned by the user does not belong to the materials, the user can calculate the thermal radiation rate corresponding to the cooking utensil owned by the user according to the material of the cooking utensil owned by the user and by using a thermal radiation rate calculation formula. For example, the merchant only measures the thermal radiation rate corresponding to the cooking utensil of stainless steel and / or iron, and the material of the cooking utensil owned by the user is aluminum. Therefore, the user can calculate the thermal radiation rate corresponding to the cooking utensil owned by the user according to the cooking utensil of aluminum and by using a thermal radiation rate calculation formula.

[0083] In S403, the target temperature is taken as the actual temperature of the object to be measured.

[0084] In some embodiments, the target temperature calculated by the above embodiments is the actual temperature of the object to be measured. The actual temperature can be output on the electronic device provided by the embodiments of the present application, and the output mode can be display on the display screen, voice broadcast, warning sound or warning light, etc.

[0085] For example, the target temperature calculated by the above embodiments is the actual temperature of the cooking appliance during cooking, and the actual temperature is displayed on the display screen of the electronic device.

[0086] As shown in Figure 5 The flowchart for calculating the thermal emissivity of the object to be measured provided by the embodiments of the present application can include the following steps:

[0087] S501, under the current atmospheric pressure, the boiling point temperature of the boiling water corresponding to the object to be measured is obtained.

[0088] In some embodiments, the current atmospheric pressure is obtained by the air pressure measuring device, and the boiling point temperature of the boiling water corresponding to the current atmospheric pressure is obtained by the air pressure boiling point mapping table.

[0089] For example, first, tap water or other unboiled water is filled in a cooking appliance, which can not be filled to the brim, but only a certain amount of water is filled; second, the water is boiled by using a gas stove, an electromagnetic oven or a fire stove; third, the current atmospheric pressure is obtained by using an air pressure measuring device, which can be independent or installed in a non-contact infrared temperature sensor; finally, the boiling point temperature of the boiling water corresponding to the current atmospheric pressure is obtained by using an air pressure boiling point mapping table.

[0090] S502, the radiation temperature corresponding to the object to be measured is obtained by using a non-contact temperature measuring device.

[0091] In some embodiments, when the object to be measured boils water, the object to be measured will radiate a certain temperature, which can be measured by using a non-contact temperature measuring device.

[0092] For example, when the water is boiled by using a cooking appliance, the cooking appliance will radiate a certain temperature, which can be measured by using a non-contact infrared temperature sensor.

[0093] S503, based on the boiling point temperature and the radiation temperature, the thermal emissivity corresponding to the object to be measured is calculated.

[0094] In some embodiments, the thermal emissivity of the object to be measured is calculated according to the following formula: Wherein, r represents the thermal emissivity of the object to be measured; T0 represents the radiation temperature of the current object to be measured, T frepresents the boiling point temperature of boiling water.

[0095] For example, the thermal emissivity of the cooking utensil is calculated according to the following formula: For example, the thermal emissivity of the cooking utensil is calculated according to the following formula: f For example, the thermal emissivity of the cooking utensil is calculated according to the following formula:

[0096] After the calculation of the thermal emissivity of the object to be measured in S503, the corresponding thermal emissivity of the object to be measured and the correspondence between the object to be measured and the thermal emissivity are also saved.

[0097] In some embodiments, after the thermal emissivity of the object to be measured is calculated, the thermal emissivity must be saved in order to calculate the target temperature of the object to be measured using the thermal emissivity and the calibrated temperature calculated in the above steps in the subsequent steps. If the calculated thermal emissivity is not saved, the target temperature of the object to be measured cannot be calculated in the subsequent steps. In addition, the correspondence between the object to be measured and the thermal emissivity is also saved, because the thermal emissivity is different for different materials of the object to be measured, so the correspondence is saved for use in the subsequent steps.

[0098] For example, after the thermal emissivity of the cooking utensil is calculated, it is saved in the electronic device in order to calculate the target temperature of the cooking utensil, i.e. the actual temperature of the cooking utensil, using the thermal emissivity and the calibrated temperature of the cooking utensil calculated in the above embodiments in the subsequent steps.

[0099] In S402, the target temperature of the object to be measured is calculated according to the corresponding thermal emissivity of the object to be measured and the calibrated temperature, which can be calculated according to the following formula: wherein T n represents the target temperature of the object to be measured; T t represents the calibrated temperature of the object to be measured, and r represents the thermal emissivity of the object to be measured.

[0100] In some embodiments, the target temperature of the object to be measured is calculated according to the thermal emissivity and the calibrated temperature of the object to be measured calculated in the above embodiments according to the following formula:

[0101] For example, the thermal emissivity of the cooking utensil calculated in the above embodiments is 0.8, and the calibrated temperature T t ​The temperature is 70℃. Using the above formula, the target temperature of the cooking appliance can be calculated to be 87.5℃.
