Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooking utensils, in particular to an induction cooker and a heating method of the induction cooker. BACKGROUND

[0002] The induction cooker is also known as the electromagnetic stove. It produces heat directly on the bottom of the pot without fire or conduction, so the thermal efficiency is greatly improved. With the progress of technology, there are induction cookers on the market that can control output power by temperature measurement. The main temperature measurement methods are as follows: the first method is to implant a temperature sensor in the pot body matched with the induction cooker to measure the temperature of the pot body. In this method, the temperature of the food in the pot is not directly measured, but the temperature of the food is approximated by the temperature of the pot. The second method is to set a wired probe for temperature measurement in the pot based on the first method, which can directly measure the temperature of the food in the pot.

[0003] In the use of the induction cooker, the above two methods have certain problems. In the first method, for the scene where there is a large amount of liquid medium in the pot, the induction cooker heats by the following steps: after the user sets the target temperature, the induction cooker heats the pot, and when the temperature of the pot measured by the temperature sensor reaches the target temperature, the induction cooker reduces the output power to reduce energy consumption and avoid the temperature of the liquid medium deviating from the target temperature due to the large temperature of the pot exceeding the target temperature. The temperature gradient from the bottom of the pot to the surface of the liquid medium is caused by the heat conduction method. The decrease of the output power of the induction cooker will cause the heating speed of the liquid medium in the pot to decrease, so that

[0004] the time required to reach the target temperature is very long. The second method directly measures the temperature of the liquid medium through the wired probe to a certain extent to reduce the slow heating speed of the liquid medium in the first method, but the wired probe not only increases the cost, but also causes inconvenience to the user's daily use experience.

[0052] The application will be further described below in connection with specific embodiments with reference to the drawings. Like numbers in different figures refer to like elements. In the following description, numerous specific details are described to provide a thorough understanding of the application. However, one of ordinary skill in the art will recognize that the application can be practiced without one or more of the specific details. In other instances, well-known structures have not been described in order to avoid obscuring the application. The following detailed description is not to be considered in a limiting sense, as one of ordinary skill in the art would be able to make or use alternative embodiments without the exercise of inventive faculty.

[0053] In addition, features, operations, or steps described in the specification can be combined in any suitable manner without departing from the scope of the application. Similarly, the steps and actions of various methods described herein can be combined in a manner other than the order described. The scope of the methods described herein therefore includes other orders than the described ones.

[0054] The serial numbers of components in the specification, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any sequence or technical meaning. The "connection" and "coupling" in the application include direct and indirect connections (couplings) unless otherwise specified.

[0055] The liquid medium referred to herein includes, but is not limited to, water, oil and other liquid substances. In the use of an induction cooker, the liquid medium itself can be a food material to be heated, such as by boiling water in an induction cooker. The liquid medium can also be used as a heat transfer medium. After heating the liquid medium to a certain temperature, food materials are added to the liquid medium. For example, when the liquid medium is cooking oil, food materials are placed in the cooking oil for frying or deep-frying after the cooking oil reaches a certain temperature.

[0056] The pot body referred to herein refers to a pot that has appeared in the past or may appear in the future and can be used with an induction cooker. From the perspective of use, the types of pot bodies include, but are not limited to, frying pans, frying pans, and soup pots. From the perspective of material, the types of pot bodies include, but are not limited to, iron pots, stainless steel pots, etc.

[0057] The specific heat coefficient, also known as specific heat or specific heat capacity, refers to the heat absorbed or released by a unit mass of a substance when its temperature decreases or increases by 1°C. It is usually represented by the letter c and has the unit of joules per kilogram per degree Celsius.

[0058] The electromagnetic oven mentioned herein is usually internally provided with a coil. An alternating current passes through the coil to generate a magnetic field. When the magnetic lines of force in the magnetic field pass through the bottom of the pot body made of a magnetic conductive material such as an iron pot or a stainless steel pot, an eddy current is generated, which causes the pot bottom to heat up rapidly to achieve the purpose of heating food. Its working process is as follows: AC power is converted into DC power by a rectifier, and then the DC power is converted into high-frequency AC power exceeding audio frequency by a high-frequency power conversion device. The high-frequency AC power is applied to the flat and hollow spiral-shaped induction heating coil, thereby generating a high-frequency alternating magnetic field. The magnetic lines of force act on the pot body, and a strong eddy current is generated in the pot body due to electromagnetic induction. When the eddy current flows against the internal resistance of the pot body, the conversion of electrical energy into heat energy is completed, and the generated Joule heat is the heat source for cooking. As can be seen from the above description, the bottom of the pot body is the source of heat, so there will be a temperature gradient of the liquid medium in the pot at different depths, which in turn leads to the problem of long heating time for the liquid medium in the pot to reach the target temperature. In other cooking fields or scenarios of heating solid media, the technical solution of the present application does not have reference value. For example, when using a microwave oven to heat food, the microwave oven emits microwaves to make the water molecules in the food move to heat, which is equivalent to heating from all around the food, which is quite different from the scenario of the present application.

[0059] The most important idea of the present application is to regard the pot body and the liquid medium as a whole to output target energy, so that the medium temperature of the liquid medium can rapidly rise to the target temperature without increasing the wired probe.

[0060] Please refer to the embodiment shown in Figure 1 The embodiment provides an electromagnetic oven 100 for use with a pot body 200. The pot body 200 can at least hold a liquid medium. The electromagnetic oven 100 includes a panel 110, an interactive device 120, a heating device 130, a weight sensor 140, a storage 150, and a processor 160.

[0061] The panel 110 is used to carry the pot body 200 matched with the electromagnetic oven 100. The material of the panel 110 includes but is not limited to ceramic, microcrystalline glass, etc.

[0062] The interaction device 120 is configured to receive the input of the user. In the present embodiment, the interaction device 120 is configured to receive at least the target temperature input by the user, where the target temperature refers to the temperature that the user expects the liquid medium to reach. In some embodiments, the interaction device 120 comprises an operation part, which comprises a full-enclosed micro-motion or touch type key circuit, and the user inputs the corresponding instruction through the operation part.

[0063] In some embodiments, the interaction device 120 further comprises a signal transmission part, which is configured to be signal-connected with a remote control device adapted to the electromagnetic oven 100. The user can input the corresponding instruction through the remote control device, for example, the electromagnetic oven 100 is equipped with a remote controller, and the user operates the remote controller to set the target temperature, or the user can set the target temperature through an app in a mobile terminal such as a mobile phone. In some embodiments, the pot body 200 adapted to the electromagnetic oven 100 also has a temperature measurement function. Specifically, a first temperature sensor 210 is implanted at the bottom of the pot body 200, and the first temperature sensor 210 sends the temperature at the bottom of the pot body 200 to the electromagnetic oven 100 through the signal transmission part after measuring the temperature at the bottom of the pot body 200, or a first temperature sensor 210 such as a handheld temperature probe or a wireless temperature probe is placed in the pot body 200, and the temperature of the liquid medium contained in the pot body 200 or the temperature at the bottom of the pot body 200 is sent to the electromagnetic oven 100 through the signal transmission part. In other embodiments, the signal transmission part can also be signal-connected with other smart or non-smart devices, for example, the signal transmission part can also receive the weight information sent by a kitchen electronic scale to obtain the weight of the food material.

[0064] In some embodiments, the interaction device 120 can also provide the required information to the user. In some embodiments, the interaction device 120 further comprises a display part, which is configured to display the information related to the electromagnetic oven 100. Specifically, the display part can adopt a light-emitting diode indication, that is, the functions and states are represented by the corresponding light-emitting diodes being on or off; the display part can also adopt a liquid crystal display, which directly and clearly displays the content; the display part can also adopt a digital display, which directly displays the set target temperature, time, fault code and other information through a digital tube; in addition, the display part can also be a fluorescent screen display, also known as a VFD (Vacuum Fluorescent Display) display. The fluorescent display has the advantages of high brightness, wide viewing angle, dynamic display pattern, clear and easy to understand, etc. The information displayed by the display part includes but is not limited to the output power of the electromagnetic oven 100, the current heating mode of the electromagnetic oven 100, and the temperature at the bottom of the pot body 200, etc.

[0065] In other embodiments, the operation part and the display part can also be an integral whole, for example, the interaction device 120 comprises a touch display screen, and the corresponding instruction is obtained based on the clicking, sliding, etc. of the user on the touch display screen.

[0066] The heating device 130 is arranged below the panel 110. In some embodiments, the heating device 130 comprises one or more coils, and an alternating current is passed through the coil to generate a magnetic field. When the magnetic lines of the magnetic field pass through the bottom of the pot 200, eddy current is generated to rapidly heat the bottom of the pot 200.

[0067] The weight sensor 140 is used to detect the weight of the object placed on the induction cooker 100. The type or specific structure of the weight sensor 140 is not limited in the present embodiment. It can be understood that the induction cooker 100 can use the existing or future weight sensor 140. In some embodiments, the weight sensor 140 is implanted in the induction cooker 100. In other embodiments, the weight sensor 140 can also be arranged on the surface of the induction cooker 100. By arranging the weight sensor 140, the induction cooker 100 has a weighing function. When the pot 200 containing the liquid medium is placed on the induction cooker 100, the weight sensor 140 can measure the total weight of the pot 200 and the liquid medium. The weight of the pot 200 can also be obtained by the weight sensor 140 when the pot 200 is placed on the induction cooker 100 before the liquid medium is poured into the pot 200.

[0068] The storage 150 can be used to store data or programs, such as the total weight of the pot 200 and the liquid medium obtained, the data generated by the processor 160, the programming instructions for the processor 160, etc. The storage 150 can be a tangible and non-transitory computer readable medium, such as a flash memory, a RAM, a ROM, an EEPROM, etc.

[0069] The processor 160 is used to execute instructions or programs, control the interaction device 120 and the heating device 130, or process the received data to generate the required calculation or judgment results.

[0070] In some embodiments, the induction cooker 100 further comprises a second temperature sensor 170. When the pot 200 is placed on the induction cooker 100, the second temperature sensor 170 can measure the temperature of the bottom of the pot 200, that is, the induction cooker 100 also has a temperature measuring function. In some embodiments, the second temperature sensor 170 is implanted in the induction cooker 100. In other embodiments, the second temperature sensor 170 can also be arranged on the surface of the induction cooker 100, or a through hole is arranged on the panel 110, and the second temperature sensor 170 is elastically arranged in the through hole.

[0071] Based on the hardware structure of the induction cooker 100 described above, please refer to Figure 2As shown in the embodiment, a heating method of an electromagnetic oven 100 is provided, which comprises:

[0072] Step A100, obtaining a target temperature set for the liquid medium.

[0073] In some embodiments, the obtaining of the target temperature occurs after the pot 200 is placed on the electromagnetic oven 100. For example, the user first places the pot 200 on the electromagnetic oven 100, then sets the target temperature, and then pours the liquid medium into the pot 200, or first places the pot 200 on the electromagnetic oven 100, then pours the liquid medium, and then sets the target temperature. In other embodiments, the obtaining of the target temperature can also occur before the pot 200 is placed on the electromagnetic oven 100, for example, the user first sets the target temperature, then places the pot 200 on the electromagnetic oven 100, and finally pours the liquid medium, or first sets the target temperature, and then places the pot 200 containing the liquid medium on the electromagnetic oven 100. From the above description, it can be seen that the embodiment does not limit the order of setting the target temperature, placing the pot 200 on the electromagnetic oven 100, and pouring the liquid medium into the pot 200.

[0074] Step A200, determining a first energy required by the liquid medium according to the target temperature.

[0075] In this step, the medium temperature of the liquid medium rises after receiving the first energy, so that outputting the first energy to the liquid medium is also a process of heating the liquid medium.

[0076] In some embodiments, as shown in the embodiment, step A200 specifically comprises: Figure 3

[0077] Step A210, obtaining a medium temperature of the liquid medium before the electromagnetic oven 100 heats the pot 200.

[0078] The purpose of the electromagnetic oven 100 heating the pot 200 is to first increase the pot temperature, and then increase the medium temperature through heat transfer. Before the electromagnetic oven 100 heats the pot 200, the liquid medium is in an initial state of being heated. In some embodiments, the heating of the electromagnetic oven 100 is triggered based on the setting of the target temperature, that is, the electromagnetic oven 100 starts heating when the setting of the target temperature is completed, which is suitable for the scenario of placing the pot 200 containing the liquid medium on the electromagnetic oven 100, and then setting the target temperature. In other embodiments, the setting of the target temperature and the start of the heating of the electromagnetic oven 100 can be performed in two steps, for example, the user first inputs the target temperature, and then presses the physical or virtual button on the electromagnetic oven 100 to start the heating of the electromagnetic oven 100, which is suitable for the scenario of setting the target temperature first, and then placing the pot 200.

[0079] ​In some embodiments, the medium temperature in front of the induction cooker 100 before heating the pot 200 is input by the user to the induction cooker 100, for example, the user can input the medium temperature according to the reading of the temperature measuring device inserted into the liquid medium, and the input medium temperature is similar to the input target temperature described above, and will not be described here.

[0080] In some embodiments, the medium temperature of the liquid medium can be measured by a pre-set temperature measuring device. For example, the temperature measuring device is inserted into the liquid medium, and after measuring the medium temperature, the temperature measuring device sends the medium temperature to the induction cooker 100 by near field communication or wired transmission.

[0081] In other embodiments, the medium temperature can also be approximately replaced by the pot temperature, for example, the pot 200 is placed on the induction cooker 100 at room temperature, and then the cooking oil is introduced into the pot 200, and in this scenario, the pot temperature of the induction cooker 100 before heating the pot 200 can be used as the oil temperature of the cooking oil before heating.

[0082] Step A220, obtaining a first temperature rise of the liquid medium according to the target temperature and the medium temperature.

[0083] For example, the liquid medium is cooking oil, the target temperature is 200℃, and the medium temperature is 20℃, and the first temperature rise is 180℃.

[0084] Step A230, obtaining the medium weight of the liquid medium.

[0085] In some embodiments, the medium weight of the liquid medium is calculated according to the total weight of the pot 200 and the liquid medium and the pot weight of the pot 200.

[0086] In some embodiments, the medium weight of the liquid medium can also be obtained by the user setting, for example, the user first measures the medium weight of the liquid medium to be poured into by the kitchen electronic scale, and then inputs the medium weight into the induction cooker 100.

[0087] In some embodiments, the induction cooker 100 also displays the medium weight of the liquid medium in the pot 200, and the user can judge whether the expected amount of liquid medium is placed in the pot 200 according to the displayed medium weight, and when the amount of liquid medium does not meet the expectation, the liquid medium can be added or part of the liquid medium can be taken out as needed without taking out the pot 200, so as to achieve better cooking effect. From the above description, it can be seen that the weighing function of the induction cooker 100 can help the user to control the accuracy of adding the liquid medium, and on the other hand, at least the medium weight required for calculating the first energy can be provided. The various effects of setting the weight sensor 140 are one of the improvements of the present application relative to the existing induction cooker 100.

[0088] Step A240, obtaining the first specific heat capacity coefficient of the liquid medium.

[0089] The first specific heat capacity coefficient is determined based on the medium type of the liquid medium. In some embodiments, the electromagnetic oven 100 stores a correspondence between different medium types and the first specific heat capacity coefficient, and the electromagnetic oven 100 obtains the first specific heat capacity coefficient of the liquid medium according to the correspondence after receiving the medium type of the liquid medium input by the user. In other embodiments, the electromagnetic oven 100 can have at least two heating modes, for example, the at least two heating modes include a frying mode, a searing mode, and a boiling mode, and each heating mode corresponds to a specific heat capacity coefficient. When the user controls the electromagnetic oven 100 to work in one of the heating modes, the electromagnetic oven 100 takes the specific heat capacity coefficient corresponding to the selected heating mode as the first specific heat capacity coefficient. For example, the specific heat capacity coefficient corresponding to the frying mode is the specific heat capacity coefficient of cooking oil, and when the user selects the frying mode, the first specific heat capacity coefficient is the specific heat capacity coefficient of cooking oil when calculating the first energy required by the liquid medium.

[0090] Step A250, calculating the first energy according to the medium weight, the first specific heat capacity coefficient, and the first temperature rise.

[0091] In some embodiments, the first energy is calculated by using the following formula (I):

[0092] ①E liquid =(W all -W pan )*C liquid *(T target -T liguid );

[0093] wherein, E liquid represents the first energy, W all represents the total weight of the pot body 200 and the liquid medium, W pan represents the pot body weight, (W all -W pan ) represents the medium weight, C liquid represents the first specific heat capacity coefficient, T target represents the target temperature, T liquid represents the medium temperature, and (T target -T liquid ) represents the first temperature rise.

[0094] Step A300, determining the second energy required to be received by the pot body 200 according to the target temperature.

[0095] In some embodiments, as shown in FIG. 3B, step A300 specifically includes: Figure 4

[0096] ​Step A310, obtain the pot temperature of the pot 200 before the induction cooker 100 heats the pot 200.

[0097] The purpose of the induction cooker 100 heating the pot 200 is to first increase the pot temperature, and then increase the medium temperature of the liquid medium through heat transfer.

[0098] In some embodiments, the setting of the target temperature triggers the heating of the induction cooker 100, that is, the induction cooker 100 starts heating as soon as the setting of the target temperature is completed, which is suitable for the scenario described above that the pot 200 containing the liquid medium is placed on the induction cooker 100, and then the target temperature is set. In other embodiments, the setting of the target temperature and the start of the heating of the induction cooker 100 can be performed in two steps, for example, the user first inputs the target temperature, and then presses the button on the induction cooker 100 to start the heating of the induction cooker 100, which is suitable for the scenario described above that the pot 200 is placed after the target temperature is set.

[0099] In some embodiments, the temperature of the bottom of the pot 200 before the induction cooker 100 heats the pot 200 is measured, and the temperature of the bottom of the pot 200 is taken as the pot temperature of the pot 200. The advantage of taking the temperature of the bottom of the pot 200 as the pot temperature is that since the heating of the induction cooker 100 to the pot 200 is essentially heating the bottom of the pot 200, taking the temperature of the bottom of the pot 200 as the pot temperature can more accurately reflect the actual pot temperature.

[0100] Step A320, obtain the second temperature rise of the pot 200 according to the target temperature and the pot temperature of the pot 200 before the induction cooker 100 heats the pot 200.

[0101] Step A330, obtain the pot weight of the pot 200.

[0102] In some embodiments, the pot weight is measured by the weight sensor 140 when the pot 200 is placed on the induction cooker 100 before the liquid medium is poured into the pot 200.

[0103] In some embodiments, the pot weight of the pot 200 is pre-stored, that is, the induction cooker 100 can be equipped with a corresponding pot 200.

[0104] In other embodiments, the induction cooker 100 pre-stores the correspondence between different pot types and pot weights, and the user can input the corresponding pot type according to the currently used pot 200 when using the induction cooker 100, and obtain the weight of the used pot 200 according to the correspondence between the pot type and the pot weight.

[0105] Step A340, obtain the second specific heat capacity coefficient of the pot 200.

[0106] In some embodiments, the electromagnetic oven 100 pre-stores the second specific heat capacity coefficient of the pot 200. In other embodiments, the electromagnetic oven 100 pre-stores a correspondence between different pot types and the second specific heat capacity coefficient, and when the electromagnetic oven 100 is used, the user can input the corresponding pot type according to the currently used pot 200, and obtain the second specific heat capacity coefficient according to the correspondence between the pot type and the second specific heat capacity coefficient. For example, the user inputs that the currently used pot 200 is a pure iron pot, and then the specific heat capacity coefficient of iron is taken as the second specific heat capacity coefficient.

[0107] Step A350, the second energy is calculated according to the pot weight, the second specific heat capacity coefficient, and the second temperature rise.

[0108] In some embodiments, the second energy is calculated by using the following formula (II):

[0109] II E pan = W pan * C pan * (T target -T current );

[0110] wherein, E pan represents the second energy, W pan represents the pot weight, C pan represents the second specific heat capacity coefficient, T target represents the target temperature, T current represents the pot temperature, and (T target -T current ) represents the second temperature rise.

[0111] Step A400, the electromagnetic oven 100 is controlled to heat the pot 200 to output the target energy. The target energy is equal to the sum of the first energy and the second energy.

[0112] The relationship between the target energy and the first energy and the second energy can be expressed by the following formula:

[0113] E target = E liquid +E pan ;

[0114] wherein, E target represents the target energy.

[0115] In some embodiments, when the pot 200 is heated, the electromagnetic oven 100 outputs energy at a set output power, and the output power is integrated to obtain the energy output by the electromagnetic oven 100 by the following formula:

[0116]

[0117] wherein, E outrepresents the energy output by the electromagnetic cooker 100, P sample represents the sampling of the output power.

[0118] In some embodiments, the electromagnetic cooker 100 works at the rated maximum power when outputting the energy, that is, the electromagnetic cooker 100 outputs the target energy at the fastest speed to further improve the heating speed of the liquid medium.

[0119] In some embodiments, when the pot temperature is used to approximate the medium temperature, there is T liquid equal to T current The target energy can be expressed by the following formula (III):

[0120] III E target = {W pan *C pan +(W all -W pan )*C liquid}*(T target -T current ).

[0121] In some embodiments, considering the heating efficiency of the electromagnetic cooker 100 and the heat loss in the heating process, the formula (III) can be further improved to obtain formula (IV):

[0122] IV E target = {W pan *C pan +(W all -W pan )*C liquid}*(T target -T current )*f;

[0123] Wherein, f is a preset proportion coefficient.

[0124] The above heating of the electromagnetic cooker 100 to the pot 200, on the one hand, does not set a wired probe in the pot 200, thereby reducing the cost, on the other hand, does not limit to measuring the pot temperature, but from the perspective of energy, respectively calculates the first energy required for the liquid medium to rise to the target temperature, and the second energy required for the pot 200, and then considers the pot 200 and the liquid medium as a whole, and outputs the target energy to the pot 200 and the liquid medium. The target energy can make the liquid medium quickly reach the target temperature or the vicinity of the target temperature, and reduce the additional power consumption.

[0125] In some embodiments, after outputting the target energy, the electromagnetic cooker 100 stops heating the pot 200. In some other embodiments, after outputting the target energy, the method further comprises the step of:

[0126] Step A500, adjust the output power of the electromagnetic cooker 100 to maintain the pot temperature of the pot 200 around the target temperature.

[0127] The purpose of this step is to maintain the medium temperature of the liquid medium around the target temperature by maintaining the pot temperature around the target temperature. This step is applicable to scenarios where the temperature of the liquid medium needs to be maintained, for example, scenarios where the oil temperature needs to be maintained in the deep-frying mode. It can be understood that "around" is clear and explicit to those skilled in the art. In the actual application of the electromagnetic cooker 100, the pot temperature is affected by various factors and is not constant. When the difference between the pot temperature and the target temperature is maintained within an acceptable range, the pot temperature can be considered to be around the target temperature.

[0128] In some embodiments, when the electromagnetic cooker 100 heats the pot 200 with the output target energy, or maintains the pot temperature of the pot 200 around the target temperature after outputting the target energy, as shown in Figure 5 , it further includes:

[0129] Step A510, monitor whether the target temperature is reset. When the target temperature is reset, step A520 is executed, otherwise, step A510 is continued.

[0130] Step A520, determine whether the reset target temperature is greater than the pot temperature when the target temperature is reset. If the reset target temperature is greater than the pot temperature when the target temperature is reset, step A530 is executed, otherwise, step A550 is executed.

[0131] The reset target temperature can be greater than the pot temperature when the target temperature is reset, or it can be less than the pot temperature when the target temperature is reset.

[0132] Step A530, re-determine the target energy according to the reset target temperature.

[0133] To re-determine the target energy, the first energy and the second energy need to be determined again according to the reset target temperature, and the process is similar to steps A200 and A300. Specifically, the reset target temperature is substituted into T target in formula ①, the medium temperature when the reset target temperature is substituted into T liquid in formula ①, and the first energy is obtained; the reset target temperature is substituted into T target in formula ②, and the pot temperature when the reset target temperature is substituted into T current in formula ②, and the second energy is obtained.

[0134] Step A540, the induction cooker 100 continues to heat the pot 200 to output the re-determined target energy.

[0135] It can be understood that the amount of energy that the induction cooker 100 has already outputted is not considered in step A540, for example, in step A100, the target temperature is set to 180℃, the medium temperature of the liquid medium to be heated and the pot temperature are both 20℃, the induction cooker 100 heats the pot 200, when the pot temperature rises to 120℃, the target temperature is re-set to 160℃, and the target energy refers to the energy that the induction cooker 100 needs to output with the pot temperature of 120℃ as the initial state.

[0136] Step A550, the output power of the induction cooker 100 is adjusted to maintain the pot temperature of the pot 200 around the target temperature.

[0137] It has been described above that the re-set target temperature can be less than or equal to the pot temperature, when the target temperature is not greater than the pot temperature, the pot 200 is not heated in the manner of outputting the target energy, but other ways of adjusting the output power of the induction cooker 100 are adopted.

[0138] In some embodiments, in step A500 and step A550, the temperature difference between the pot temperature of the pot 200 and the target temperature is inputted, and a pre-set closed-loop control algorithm is adopted to adjust the output power of the induction cooker 100, which can include but is not limited to the classic PID control algorithm, etc.

[0139] Please refer to the embodiment shown in Figure 6 , Figure 6 A heating method of the induction cooker 100 is provided, which is applied when the induction cooker 100 carries the pot 200 containing the liquid medium, and includes:

[0140] Step B100, the pot temperature of the pot 200 is obtained, and the output power of the induction cooker 100 is adjusted so that the pot temperature of the pot 200 is maintained around the pre-set target temperature.

[0141] The purpose of this step is to maintain the pot temperature of the pot 200 that has been heated around the target temperature. The heating method in the last embodiment described above can be used to heat the pot temperature to the target temperature, or other heating methods that have existed in the past or may appear in the future can be used to heat the pot temperature to the target temperature.

[0142] In some embodiments, the temperature of the bottom of the pot 200 is measured and taken as the pot temperature of the pot 200. The advantage of taking the temperature of the bottom of the pot 200 as the pot temperature is that, since the electromagnetic cooker 100 heats the pot 200 substantially by heating the bottom of the pot 200, taking the temperature of the bottom of the pot 200 as the pot temperature can more accurately reflect the actual pot temperature.

[0143] In some embodiments, the temperature difference between the pot temperature of the pot 200 and the target temperature is taken as the input, and a pre-set closed-loop control algorithm is used to adjust the output power of the electromagnetic cooker 100. The closed-loop control algorithm can include, but is not limited to, a classic PID control algorithm, etc.

[0144] Step B200, monitor whether the target temperature is reset. When the target temperature is reset, step B300 is executed, otherwise, step B100 is continued.

[0145] The method of resetting the target temperature is similar to the method of setting the target temperature in step A100, which will not be described here.

[0146] Step B300, determine whether the reset target temperature is greater than the pot temperature when the target temperature is reset. If the reset target temperature is greater than the pot temperature when the target temperature is reset, step B400 is executed, otherwise, step B100 is continued.

[0147] During the process of maintaining the pot temperature, the reset target temperature can be greater than the pot temperature when the target temperature is reset, or it can be less than the pot temperature when the target temperature is reset.

[0148] Step B400, determine the first energy required to be accepted by the liquid medium according to the reset target temperature.

[0149] In this step, the medium temperature of the liquid medium will rise after accepting the first energy. In some embodiments, step B400 specifically includes:

[0150] Step B410, obtain the medium temperature of the liquid medium when the target temperature is reset.

[0151] In some embodiments, the medium temperature when the target temperature is reset is input by the user to the electromagnetic cooker 100. For example, the user can input the medium temperature to the electromagnetic cooker 100 according to the reading of the temperature measuring device inserted into the liquid medium. The way of inputting the medium temperature is similar to the way of inputting the target temperature described above, which will not be described here.

[0152] In some embodiments, the medium temperature of the liquid medium can be measured by a pre-set temperature measuring device. For example, the temperature measuring device is inserted into the liquid medium, and after measuring the medium temperature, the temperature measuring device sends the medium temperature to the induction cooker 100 by near field communication or wired transmission.

[0153] In other embodiments, the medium temperature can also be approximately replaced by the pot temperature, that is, the pot temperature of the pot 200 when the target temperature is reset is obtained, and then the pot temperature is taken as the medium temperature.

[0154] Step B420, obtaining the first temperature rise of the liquid medium according to the reset target temperature and the medium temperature.

[0155] Step B430, obtaining the medium weight of the liquid medium.

[0156] In some embodiments, the medium weight is calculated according to the total weight of the pot 200 and the liquid medium and the pot weight of the pot 200.

[0157] In some embodiments, the medium weight of the liquid medium can also be obtained by user setting, for example, the user first measures the medium weight of the liquid medium to be poured by the kitchen electronic scale, and then inputs the medium weight into the induction cooker 100.

[0158] In some embodiments, the induction cooker 100 also displays the medium weight of the liquid medium in the pot 200, and the user can judge whether the expected amount of liquid medium is placed in the pot 200 according to the displayed medium weight, and when the amount of liquid medium does not meet the expectation, the user can continue to add or remove a part of the liquid medium according to the need without taking out the pot 200, so as to achieve better cooking effect. From the above description, it can be seen that the weighing function of the induction cooker 100 can help the user to control the precision of adding the liquid medium on the one hand, and on the other hand, at least the medium weight required for calculating the first energy can be provided. The multiple effects of setting the weight sensor 140 are one of the improvements of the present application relative to the existing induction cooker 100.

[0159] Step B440, obtaining the first specific heat capacity coefficient of the liquid medium.

[0160] The first specific heat capacity coefficient is determined based on the medium type of the liquid medium. In some embodiments, the electromagnetic oven 100 stores a correspondence between different medium types and the first specific heat capacity coefficient, and the electromagnetic oven 100 obtains the first specific heat capacity coefficient of the liquid medium according to the correspondence after receiving the medium type of the liquid medium input by the user. In other embodiments, the electromagnetic oven 100 can have at least two heating modes, for example, the at least two heating modes include a frying mode, a sautéing mode, and a boiling mode, etc., and each heating mode corresponds to a specific heat capacity coefficient. When the user controls the electromagnetic oven 100 to work in one of the heating modes, the electromagnetic oven 100 takes the specific heat capacity coefficient corresponding to the selected heating mode as the first specific heat capacity coefficient. For example, the specific heat capacity coefficient corresponding to the frying mode is the specific heat capacity coefficient of cooking oil, and the first specific heat capacity coefficient is the specific heat capacity coefficient of cooking oil when the user selects the frying mode and calculates the first energy required by the liquid medium.

[0161] Step B450, calculating the first energy according to the medium weight, the first specific heat capacity coefficient, and the first temperature rise.

[0162] In some embodiments, the first energy can be calculated by using Formula ①, wherein the reset target temperature is substituted into T target the medium temperature at the time of resetting the target temperature is substituted into T liquid to obtain the first temperature rise.

[0163] Step B500, determining the second energy required to be accepted by the pot body 200 according to the reset target temperature.

[0164] In some embodiments, Step B500 specifically includes:

[0165] Step B510, obtaining the pot body temperature of the pot body 200 at the time of resetting the target temperature.

[0166] In some embodiments, the electromagnetic oven 100 can also display the measured pot body temperature, thereby more intuitively providing the user with information about the temperature change.

[0167] Step B520, obtaining the second temperature rise of the pot body 200 according to the reset target temperature and the pot body temperature at the time of resetting the target temperature.

[0168] Step B530, obtaining the pot body weight of the pot body 200.

[0169] In some embodiments, the pot body weight of the pot body 200 is measured by the weight sensor 140 when the pot body 200 is placed on the electromagnetic oven 100 before the liquid medium is poured into the pot body 200.

[0170] In some embodiments, the pot body weight of the pot body 200 is pre-stored, that is, the electromagnetic oven 100 can be equipped with a corresponding pot body 200.

[0171] In some embodiments, the electromagnetic oven 100 pre-stores the correspondence between different pot types and pot weights, and the user can input the corresponding pot type according to the currently used pot 200 when using the electromagnetic oven 100, and obtain the weight of the used pot 200 according to the correspondence between the pot type and the pot weight.

[0172] Step B540, obtaining the second specific heat capacity coefficient of the pot 200.

[0173] In some embodiments, the electromagnetic oven 100 pre-stores the second specific heat capacity coefficient of the pot 200. In other embodiments, the electromagnetic oven 100 pre-stores the correspondence between different pot types and the second specific heat capacity coefficient, and the user can input the corresponding pot type according to the currently used pot 200 when using the electromagnetic oven 100, and obtain the second specific heat capacity coefficient according to the correspondence between the pot type and the second specific heat capacity coefficient. For example, the user inputs that the currently used pot 200 is a pure iron pot, and then the specific heat capacity coefficient of iron is taken as the second specific heat capacity coefficient.

[0174] Step B550, calculating the second energy according to the pot weight, the second specific heat capacity coefficient, and the second temperature rise.

[0175] In some embodiments, the second energy can be calculated by using formula (II), wherein the reset target temperature is substituted into T target , the pot temperature at the time of resetting the target temperature is substituted into T current , and the second temperature rise is obtained.

[0176] Step B600, controlling the electromagnetic oven 100 to output the target energy to the pot 200, wherein the target energy is the sum of the first energy and the second energy.

[0177] The relationship between the target energy and the first energy and the second energy can be expressed by the following formula:

[0178] E target = E liquid + E pan ;

[0179] Wherein, E target represents the target energy.

[0180] In some embodiments, when heating the pot 200, the electromagnetic oven 100 outputs energy at a set output power, and simultaneously integrates the output power to obtain the energy output by the electromagnetic oven 100 by the following formula:

[0181]

[0182] Wherein, E outP represents the energy output by the electromagnetic cooker 100 sample represents the sampling of the output power.

[0183] In some embodiments, the electromagnetic cooker 100 works at the rated maximum power when outputting the energy, that is, the electromagnetic cooker 100 outputs the target energy at the fastest speed to further improve the heating speed of the liquid medium.

[0184] In some embodiments, when the pot temperature is used to approximate the medium temperature, there is T liquid equals T current The target energy can be represented by formula (III), and in some embodiments, considering the heating efficiency of the electromagnetic cooker 100 and the heat loss in the heating process, formula (III) can be improved to obtain formula (IV).

[0185] By outputting the target energy determined according to the reset target temperature, the medium temperature of the liquid medium can quickly reach the vicinity of the reset target temperature. In some embodiments, after step B600, step B100 can be further executed, that is, the pot temperature is continuously maintained near the reset target temperature.

[0186] The above embodiments are applicable to the scenario where the target temperature is changed after the pot 200 has been heated, for example, the liquid medium is cooking oil, and the target temperature is 200°C. After the cooking oil is heated to 200°C, the electromagnetic cooker 100 maintains the pot temperature near 200°C to keep the oil temperature. If the user increases the target temperature to 250°C, the electromagnetic cooker 100 can determine the target energy according to the method of the above embodiments and output the target energy based on the current pot temperature.

[0187] The above electromagnetic cooker effectively solves the slow heating problem of the current electromagnetic cooker when heating the liquid medium at a lower cost, and simplifies the user's operation.
