[0030] At present, after the expansion of the application scenarios of microwave cooking devices, microwave cooking devices have been able to enter people's lives as multi-scenario cooking appliances that integrate microwave steaming and baking. In addition to simple heating, they can also be used as ovens and steamers, and can even be used to set up frying and baking trays for frying and baking food. However, the current application of microwave cooking devices in the frying and baking tray scenario is still in its infancy, requiring manual observation and judgment of the cooking status of food, requiring frequent manual intervention, and not monitoring the real-time temperature of the baking tray. Temperature is crucial to the quality of frying and baking. How to monitor the real-time temperature of the microwave absorbing baking tray through hardware and input it as feedback into the control system of the microwave oven so that the microwave oven can adjust the temperature of the baking tray by adjusting the power, thereby realizing a more intelligent automatic cooking menu, is a problem to be solved.

[0031] This article provides a cooking control method for controlling the temperature of the following cooking device. Figure 1 , Figure 1 It is a simplified structural diagram of an embodiment of a cooking device of the present application.

[0032] The cooking device 100 includes a cabinet 110, a microwave generator 120, a temperature sensor 130, and a food tray mounting portion (not shown).

[0033] Among them, the box body 110 has a cooking cavity 140, and the food pan mounting portion is arranged on the inner wall of the box body 110 facing the cooking cavity 140, for mounting a food pan 150. When the food pan 150 is placed in place through the food pan mounting portion, the cooking cavity 140 is divided into a first cavity 141 and a second cavity 142. The microwave generator 120 is arranged on a side of the box body 110 close to the first cavity 141, for heating the food pan 150. The temperature sensor 130 is arranged on a side of the box body 110 close to the second cavity 142, and the temperature sensor 130 is used to detect the surface temperature of the food pan 150.

[0034] It can be understood that the first cavity 141 is the lower half of the cooking cavity 140, and the second cavity 142 is the upper half of the cooking cavity 140. In one application scenario, the food pan 150 is mounted in the cooking cavity 140 through the food pan mounting portion. When the microwave generator 120 emits microwaves, the microwaves propagate in the first cavity 141, heating the food pan 150, increasing the temperature of the outer surface of the food pan 150, and the food on the food pan 150 can be fried by the upper surface temperature of the food pan 150. In another application scenario, the food pan 150 is not used to cook food, and the container containing the food can be directly placed in the cooking cavity, and the microwave energy emitted by the microwave generator 120 is used to heat the food.

[0035] The microwave generator 120 is disposed on one side of the box 110 close to the first cavity 141, specifically, at a position where the bottom and / or side wall of the box 110 is located below the food pan 150; the temperature sensor 130 is disposed on one side of the box 110 close to the second cavity 142, specifically, at a position where the top or side wall of the box 110 is located above the food pan 150. After the food pan 150 is placed in place, the microwave generator 120, the first cavity 141 and the lower surface of the food pan 150 are located in the same space, and the temperature sensor 130, the second cavity 142 and the upper surface of the food pan 150 are located in the same space.

[0036] The microwave generator 120 is a magnetron, which can generate microwaves with a vibration frequency of 2.45 billion times per second. Such microwaves, which are invisible to the naked eye, can penetrate food to a depth of 5 cm and cause water molecules in the food to move. The violent movement generates a large amount of heat energy, thereby heating the food plate 150 and the food.

[0037] The temperature sensor 130 is, for example, an infrared temperature sensor, which is used to detect the temperature of the food pan 150 according to the infrared rays emitted by the food pan 150. In some embodiments, a small hole may be provided on the inner surface of the top or side wall of the box body 110, and the temperature sensor 130 is provided in the small hole. The temperature sensor 130 detects the infrared rays emitted from the surface of the food pan 150 through the small hole, and then measures the temperature of the surface of the food pan 150.

[0038] The side of the food pan 150 close to the second cavity 142 is provided with an absorbing layer 160, which is used to absorb the microwaves emitted by the microwave generator 120 and convert the microwave energy into heat and transfer it to the food pan 150. The absorbing layer 160 evenly covers the side of the food pan 150 close to the second cavity 142. When the microwave generator 120 is working, the absorbing layer 160 can evenly absorb the microwaves and convert the microwaves into heat energy and provide it to the food pan 150, so that the food on the food pan 150 is evenly heated.

[0039] The absorbing layer 160 is, for example, an absorbing patch, an absorbing coating, or an absorbing plate, etc. The microwave absorber in the absorbing layer 160 may include one or more of a magnetic absorber and a non-magnetic absorber, wherein the magnetic absorber may include one or more of ferrite, carbonyl iron, and magnetic alloy powder, and the non-magnetic absorber may include one or more of carbon black, graphene, carbon nanotubes, silicon carbide ceramics, and conductive polymers.

[0040] The thickness of the wave absorbing layer 160 may be any value between 0.2 mm and 5 mm.

[0041] In the cooking device 100 of this embodiment, since the cooking cavity 140 is separated by the food plate 150, the microwaves emitted by the microwave generator 120 are only propagated in the first cavity 141, and the second cavity 142 has no microwave heat source. The food placed in the food plate 150 is heated only by the temperature of the surface of the food plate 150, so that the cooking device 100 can be used to fry food, such as frying steak, frying eggs, and pancakes. When frying food using the cooking device 100 provided by this embodiment, the output power of the microwave generator 120 can be adjusted according to the surface temperature of the food plate 150 detected by the temperature sensor 130, so as to achieve automatic adjustment of the cooking temperature, reduce manual participation, and provide convenience for cooking.

[0042] This document also provides a control method, which can control the cooking process according to the temperature feedback from the temperature sensor 130 to reduce the manual participation in the cooking process. Please refer to the embodiments provided below for details.

[0043] See also Figure 2 , Figure 2 1 is a flowchart of an embodiment of a control method for a cooking device of the present application. It should be noted that if there are substantially the same results, this embodiment is not limited to Figure 2 The process sequence shown is limited. This embodiment includes the following steps:

[0044] Step S11: Determine cooking parameters.

[0045] The cooking parameters include the corresponding relationship between the cooking time and the cooking temperature. In this embodiment, the cooking temperature is the temperature requirement for the food plate 150 during the heating process.

[0046] Specifically, during the cooking process of food, the cooking temperature, heating power, etc. are controlled according to the time and temperature relationship in the cooking parameters.

[0047] In some embodiments, for a single temperature control cooking strategy, the cooking parameters may be presented in the form of a temperature-time comparison table, for example, the cooking parameters are shown in the following table:

[0048] Cooking Stage Cooking Temperature Cooking time Phase 1 T1 t1 Phase 2 T2 t2

[0049] The stage 1 and stage 2 shown in the above table represent different cooking stages, T1 represents the cooking temperature of stage 1, t1 represents the duration of cooking in stage 1, T2 represents the cooking temperature of stage 2, and t2 represents the duration of cooking in stage 2. That is, under the cooking parameters specified in this embodiment, first, heating is continued for t1 time at the temperature represented by T1 in stage 1, and then heating is continued for t2 time at the temperature represented by T2 in stage 2.

[0050] In another embodiment, for a cooking strategy with complex temperature control, the cooking parameters may be presented in the form of a temperature-time curve. Figure 3 , Figure 3 This is a schematic diagram of an embodiment of the cooking parameters of the present application. In the cooking parameters of this embodiment, the temperature rises to T3 at a fixed rate in the time period of 0 to t3, and is kept heated at T3 in the time period of t3 to t5. When the cooking operation is performed according to this cooking parameter, the temperature is first heated at a heating rate of T3 / t3 for a time period of t3, and then continuously heated at the temperature represented by T3 in the time periods of t3-t4 and t4-t5.

[0051] The cooking parameters can be selected according to the control instructions received by the control center. Specifically, an operation panel can be provided on the cooking device. After the operator prepares the ingredients to be cooked and puts them into the cooking device, the operator selects the cooking program on the operation panel according to the ingredients and maturity, and issues control instructions accordingly. The control center determines the corresponding cooking parameters according to the received control instructions. For example, the control panel can display cooking programs such as "medium-rare steak", "medium-rare steak", and "sunny egg". By selecting different cooking programs, the corresponding cooking parameters can be called for cooking.

[0052] The operation panel may include one or more knobs or buttons, and the operator can select the cooking program to be enabled by pressing a button or turning a knob. The operation panel may also include a touch operation interface, and the operator can pull out an operation menu on the touch operation interface and click to select the cooking program to be enabled.

[0053] Step S12: During the operation of the microwave generator, the detected temperature detected by the temperature sensor is obtained.

[0054] In this step, when the microwave generator 120 is working, the temperature sensor 130 works synchronously to detect the temperature of the food pan 150 to obtain the detected temperature. Since the heat source in the second cavity 142 is the heat transferred from the upper surface of the food pan 150, the detected temperature obtained by the temperature sensor 130 can represent the temperature of the upper surface of the food pan 150.

[0055] Step S13: Based on the cooking parameters and the detected temperature, the output power of the microwave generator is controlled.

[0056] During the cooking process, according to the corresponding relationship between the cooking temperature and the cooking time determined by the cooking parameters, the detected temperature at the corresponding moment needs to be controlled to be the same as or close to the cooking temperature.

[0057] The cooking parameters may include a preheating section. The preheating section is used to preheat the food pan 150 so that the food pan 150 can reach a set temperature before cooking the food, and the temperature of the food pan 150 is stabilized at the set temperature. After putting the food in, the food can be evenly heated in a temperature-stable environment, which helps to quickly cook the food, and can also prevent uneven heating of the food from causing partial undercooking or burning.

[0058] It can be understood that the purpose of the preheating stage is to make the temperature of the food tray 150 reach the preheating temperature corresponding to the preheating stage. Figure 3 Taking the cooking curve shown as an example, time 0 to time t3 is the preheating stage, and the preheating temperature corresponding to the preheating stage is the temperature represented by T3. The goal of the preheating stage is to heat the temperature of the food plate 150 to the temperature represented by T3.

[0059] See also Figure 4 , Figure 4 1 is a schematic flow chart of an embodiment of the heating control method for the preheating stage of the present application. It should be noted that if there are substantially the same results, this embodiment is not limited to Figure 4 The process sequence shown is limited. This embodiment includes the following steps:

[0060] Step S21: In the preheating stage, the microwave generator is controlled to heat the food dish according to a first set power.

[0061] During preheating in this step, the microwave generator 120 heats the food pan 150 according to a fixed first set power, so that the temperature of the food pan 150 continues to rise.

[0062] Step S22: in response to the detected temperature reaching the preheating temperature corresponding to the preheating section, controlling the microwave generator to stop working.

[0063] In the preheating stage, the temperature of the food plate 150 is detected, and the detected temperature is compared with the preheating temperature. If the detected temperature reaches the preheating temperature, it is determined that the preheating is completed, otherwise, the preheating continues.

[0064] See also Figure 5 , Figure 5 It is a schematic flow chart of another embodiment of the heating control method for the preheating section of the present application. It should be noted that if there is substantially the same result, this embodiment is not used. Figure 5The process sequence shown is limited. This embodiment includes the following steps:

[0065] Step S31: Determine to enter the preheating stage.

[0066] Among them, the cooking parameters can be divided into multiple cooking stages in chronological order, and the preheating stage is usually ranked first. When the first cooking stage is executed, it is determined to enter the preheating stage; in addition, each cooking stage can also be labeled, and whether to enter the preheating stage is determined by identifying the label.

[0067] Step S32: controlling the microwave generator to heat the food dish according to the first set power.

[0068] This step is the same as step S21 and will not be repeated here.

[0069] Step S33: acquiring the detected temperature at every preset time interval.

[0070] In this step, the temperature data detected by the temperature sensor 130 is acquired at a preset interval, and the preset interval is 0.1 to 5 seconds, such as 1 second, 2 seconds, 0.5 seconds, etc.

[0071] Step S34: Determine whether the detected temperature reaches the preheating temperature.

[0072] If the detected temperature is greater than or equal to the preheating temperature, it is determined that the detected temperature has reached the preheating temperature, and step S35 is executed to control the microwave generator 120 to suspend operation; if the detected temperature is less than the preheating temperature, it is determined that the detected temperature has not reached the preheating temperature, and step S32 is executed to continue heating the food plate 150 according to the first preset power.

[0073] Step S35: Control the microwave generator to stop working.

[0074] When the preheating temperature is reached, it indicates that the purpose of the preheating stage is achieved, and the microwave generator 120 is controlled to stop working, so that the operator can put the prepared ingredients on the food plate 150.

[0075] After this step, a prompt message may be issued to indicate that the preheating is complete, such as a flashing indicator light or a prompt tone.

[0076] The cooking parameters may include a cooking section, which is used to continuously or intermittently heat the food pan 150 so that the food on the food pan 150 absorbs heat and is cooked.

[0077] See also Figure 6 , Figure 6 1 is a schematic flow chart of an embodiment of a heating control method for a cooking section of the present application. It should be noted that if there is substantially the same result, this embodiment is not used. Figure 6The process sequence shown is limited. This embodiment includes the following steps:

[0078] Step S41: Compare the detected temperature with the corresponding cooking temperature to obtain a comparison result.

[0079] The detected temperature can be regarded as the real-time temperature of the food plate 150, and the cooking temperature is the temperature of the food plate 150 corresponding to the cooking parameter at that moment. Whether the current detected temperature deviates from the cooking temperature and the degree of deviation can be determined based on the comparison result of the detected temperature and the cooking temperature.

[0080] Step S42: controlling the output power of the microwave generator according to the comparison result so that the difference between the detected temperature and the cooking temperature does not exceed a preset temperature difference threshold.

[0081] The output power of the microwave generator 120 may be increased when the detected temperature is low, and the output power of the microwave generator 120 may be reduced or the microwave generator 120 may be controlled to stop working when the detected temperature is high.

[0082] See also Figure 7 , Figure 7 FIG. 1 is a flow chart showing another embodiment of the heating control method for the cooking section of the present application. It should be noted that if there is substantially the same result, this embodiment is not used as Figure 7 The process sequence shown is limited. This embodiment includes the following steps:

[0083] Step S51: Compare the detected temperature with the corresponding cooking temperature.

[0084] The comparison operation in this step may include two aspects: one is the size relationship between the detection temperature and the corresponding cooking temperature, and the other is the difference between the detection temperature and the cooking temperature.

[0085] Step S52: Determine whether the detected temperature is lower than the corresponding cooking temperature, and whether the difference between the detected temperature and the cooking temperature exceeds a first temperature difference threshold.

[0086] If it is determined in this step that the detected temperature is lower than the corresponding cooking temperature, and the difference between the detected temperature and the cooking temperature exceeds the first temperature difference threshold, it indicates that the detected temperature is too low and the firepower needs to be increased, and step S53 is executed; otherwise, step S54 is executed.

[0087] Step S53: increasing the output power of the microwave generator.

[0088] Step S54: Determine whether the detected temperature is higher than the corresponding cooking temperature, and whether the difference between the detected temperature and the cooking temperature exceeds a second temperature difference threshold.

[0089] If it is determined in this step that the detected temperature is higher than the corresponding cooking temperature, and the difference between the detected temperature and the cooking temperature exceeds the second temperature difference threshold, indicating that the detected temperature is too high, step S55 is executed; otherwise, step S56 is executed.

[0090] Step S55: reducing the output power of the microwave generator or controlling the microwave generator to stop working.

[0091] The reduction value of the output power of the microwave generator 120 can be determined according to the numerical range of the difference between the detection temperature and the cooking temperature. For example, if the difference is between the second temperature difference threshold and the third temperature difference threshold, P1 is reduced on the basis of the previous output power; if the difference is between the third temperature difference threshold and the fourth temperature difference threshold, P2 is reduced on the basis of the previous output power; if the difference exceeds the fourth temperature difference threshold, the microwave generator 120 is controlled to suspend operation, and the timing of continuing to work of the microwave generator 120 is subsequently controlled according to the comparison result of step S51.

[0092] Step S56: Keep the output power of the microwave generator unchanged.

[0093] In this step, the output power of the microwave generator 120 is not adjusted, and the microwave generator 120 continues to operate at the previous output power.

[0094] Different from the prior art, the cooking device control method provided in the present embodiment can detect the temperature of the food plate 150 in real time, obtain the detected temperature, and compare it with the cooking temperature determined by the cooking parameters, and control the output power of the microwave generator 120 according to the comparison result to realize the control of the temperature of the food plate 150. The temperature control accuracy of the food plate 150 is high, and the temperature adjustment is sensitive and convenient. When the food plate 150 is used for microwave cooking, manual participation can be greatly reduced, and manpower is liberated, so that the microwave cooking device can fry food in a highly intelligent manner, which not only broadens the application scenarios of the microwave cooking device, but also can highly automatically adjust the temperature in the application scenario of frying food, which is easy to use.

[0095] See also Figure 8 , Figure 8 The cooking device 200 includes a microwave generator 210, a temperature sensor 220, a memory 230, a controller 240, and a cabinet and a food tray installation part, wherein the cabinet and the food tray installation part are not shown.

[0096] The box has a cooking cavity, and the food tray mounting portion is arranged on the inner wall of the box facing the cooking cavity. When the food tray is placed in place by the food tray mounting portion, the cooking cavity is divided into a first cavity and a second cavity. The microwave generator 210 is arranged on a side of the box close to the first cavity, and is used to heat the food tray. The temperature sensor 220 is arranged on a side of the box close to the second cavity, and is used to detect the surface temperature of the food tray.
