Description

Technical Field

[0001] This invention relates to the field of microwave cooking appliance technology, and more specifically, to a control method, control device, microwave cooking appliance, and computer-readable storage medium for heating shelled food. Background Technology

[0002] In related technologies, microwave ovens can be used to heat or cook food. However, microwave ovens are generally not suitable for heating eggs. Because eggshells are airtight, microwaving eggs can easily cause a large amount of steam to be generated inside the egg in a short period of time, increasing the pressure and potentially causing an explosion. Summary of the Invention

[0003] The present invention provides a control method, control device, microwave cooking appliance, and computer-readable storage medium for heating shelled food, which can solve the problem of explosions that easily occur when microwave cooking appliances heat shelled food.

[0004] The control method for heating shelled food according to embodiments of the present invention is used in a microwave cooking appliance, the microwave cooking appliance including a cooking cavity and a microwave generator. The control method includes controlling the microwave generator to operate at a first microwave power to perform a first heating stage on the shelled food, the first microwave power being determined based on the initial surface temperature of the shelled food and the cavity temperature of the cooking cavity; when the surface temperature of the shelled food reaches a first set temperature, controlling the microwave generator to operate at a second microwave power to perform a second heating stage on the shelled food, the second microwave power being less than the first microwave power.

[0005] In this way, by monitoring the surface temperature of shelled food, the state of the shelled food during the heating process can be determined, and the microwave power of the microwave generator for heating the shelled food can be continuously adjusted according to the surface temperature. This can prevent the rapid generation of a large amount of steam inside the shelled food in a short period of time during the heating process, thereby avoiding the explosion of the shelled food during the heating process to a certain extent.

[0006] In some embodiments, controlling the microwave generator to operate at a second microwave power to perform a second heating stage on the shelled food when the surface temperature of the shelled food reaches a first set temperature includes controlling the microwave generator to stop operating for a preset time and then operate at the second microwave power again when the surface temperature of the shelled food reaches the first set temperature.

[0007] In this way, by controlling the microwave generator to stop working after the surface temperature of the shelled food reaches a certain level, and then resuming work after the preset food, the temperature of the shelled food can be lowered during the period when the microwave generator is not working, thus preventing the generation of a large amount of steam inside the shelled food in a short period of time, thereby preventing the shelled food from exploding.

[0008] In some embodiments, controlling the microwave generator to operate at a second microwave power to perform a second heating stage on the shelled food when the surface temperature of the shelled food reaches a first set temperature includes controlling the microwave generator to operate at a second microwave power to perform at least two second heating stages on the shelled food when the surface temperature of the shelled food reaches the first set temperature.

[0009] In this way, when the surface temperature of the shelled food reaches the preset value, by heating the shelled food in multiple heating stages and adjusting the power of the microwave generator during the switching of heating stages, the microwave generator can maintain a low heating power to heat the shelled food during the heating process, avoiding the generation of a large amount of steam inside the shelled food in a short period of time, thereby preventing the shelled food from exploding.

[0010] In some embodiments, when the surface temperature of the shelled food reaches the first set temperature, controlling the microwave generator to operate at a second microwave power to perform at least two second heating stages on the shelled food includes, during the execution of the previous second heating stage, when the surface temperature of the shelled food reaches the second set temperature, controlling the microwave generator to operate at the second microwave power to perform a next second heating stage on the shelled food, wherein the second set temperature is greater than the first set temperature, and the second set temperature of the next second heating stage is greater than the second set temperature of the previous second heating stage.

[0011] Thus, by controlling the microwave generator to operate at a second microwave power to perform the next second heating stage on the shelled food, and the second set temperature of the next second heating stage is greater than the second set temperature of the previous second heating stage, the temperature of the shelled food can be increased while preventing the shelled food from exploding.

[0012] In some implementations, the second set temperature ranges from 65 degrees Celsius to 75 degrees Celsius.

[0013] Thus, when the surface temperature of shelled food reaches 65 to 75 degrees Celsius, the food is almost cooked through. By adjusting the power of the microwave generator, the food can be prevented from being overheated, which would cause nutrient loss and affect the taste.

[0014] In some embodiments, during the execution of the previous second heating stage, when the surface temperature of the shelled food reaches the second set temperature, controlling the microwave generator to operate at the second microwave power to execute the next second heating stage on the shelled food includes, during the execution of the previous second heating stage, when the surface temperature of the shelled food reaches the second set temperature, controlling the microwave generator to stop operating for a preset time before executing the next second heating stage.

[0015] In this way, by controlling the microwave generator to stop working after the surface temperature of the shelled food reaches a certain level, and then resuming work after the preset food, the temperature of the shelled food can be lowered during the period when the microwave generator is not working, thus preventing the generation of a large amount of steam inside the shelled food in a short period of time, thereby preventing the shelled food from exploding.

[0016] In some implementations, the preset duration ranges from 3 seconds to 15 seconds.

[0017] Thus, by setting the preset duration for when the microwave generator stops working to a range of 3 to 15 seconds, the temperature of shelled food can be reduced to a level that will not cause an explosion. If the preset duration for when the microwave generator stops working is less than 3 seconds, the temperature of the shelled food will drop too little, which may easily cause an explosion. If the preset duration for when the microwave generator stops working is greater than 15 seconds, the temperature of the shelled food will drop too much, which will prolong the heating time and reduce the heating efficiency.

[0018] In some embodiments, the first microwave power ranges from 300 watts to 600 watts, the first set temperature ranges from 45 degrees Celsius to 60 degrees Celsius, and the second microwave power ranges from 50 watts to 200 watts.

[0019] Thus, by setting the microwave generator's power to 300 to 600 watts, heating efficiency can be improved while preventing the shelled food from exploding. When the surface temperature of the shelled food reaches 45 to 60 degrees Celsius, adjusting the microwave generator's power can prevent excessive heat from causing a large amount of steam to be generated inside the shell in a short time. By adjusting the microwave generator's power to 50 to 200 watts, the shelled food can be heated while preventing the rapid generation of a large amount of steam inside the shell, thereby preventing the shelled food from exploding.

[0020] In some embodiments, after the step of controlling the microwave generator to operate at a second microwave power to perform a second heating stage on the shelled food, the control method includes controlling the microwave generator to shut down so that the shell of the shelled food remains intact when the microwave generator heats the shelled food to a third set temperature at the second microwave power.

[0021] Thus, when the microwave generator heats the shelled food to the third set temperature at the second microwave power, the microwave generator is turned off. At this point, the shelled food is fully cooked. By turning off the microwave generator, the shelled food can be prevented from being overheated, thus avoiding nutrient loss and affecting the taste.

[0022] In some embodiments, the third set temperature ranges from 75 degrees Celsius to 82 degrees Celsius.

[0023] Thus, by heating shelled food to between 75 and 82 degrees Celsius, it can be determined that the shelled food is fully cooked and does not need to be heated further, thereby saving energy consumption and reducing costs.

[0024] The control device of the present invention is used in a microwave cooking appliance. The control device includes a processor and a memory. The memory stores a computer program. When the computer program is executed by the processor, it implements the steps of the control method for heating shelled food as described in any of the above embodiments.

[0025] The microwave cooking appliance of the present invention includes a control device, a microwave generator, and a cooking cavity. The control device is electrically connected to the microwave generator and is the control device described in the above embodiment.

[0026] The computer-readable storage medium of the present invention stores a computer program thereon, which, when executed by a processor, implements the steps of the control method for heating shelled food as described in any of the above embodiments.

[0041] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.

[0042] Among related technologies, the microwave cooking appliance industry has emerged and developed rapidly with the application of microwave heating technology. Today, using microwave cooking appliances to heat or cook food has become a common practice in households both in China and abroad, such as heating milk, boiling sweet potatoes, or cooking noodles. However, heating shelled foods has remained a challenge for microwave ovens in many dishes.

[0043] Because shelled foods are not airtight, when heated, they generate steam inside, increasing pressure and potentially leading to an explosion—a very dangerous situation. Furthermore, microwave cooking appliances generally have high microwave power and feature overall heating; therefore, when heating shelled foods, they generate a large amount of steam inside the food in a short time, causing a rapid increase in pressure and potentially resulting in an explosion.

[0044] To address the aforementioned technical problems, this invention provides a control method for heating shelled food.

[0045] Please see Figures 1 to 4 The control method for heating shelled food according to an embodiment of the present invention is used in a microwave cooking appliance 100, which includes a cooking cavity 20 and a microwave generator 10. The control method includes:

[0046] Step 011: Control the microwave generator 10 to operate at a first microwave power to perform a first heating stage on the shelled food. The first microwave power is determined based on the initial surface temperature of the shelled food and the oven cavity temperature of the cooking cavity 20.

[0047] Step 012: When the surface temperature of the shelled food reaches the first set temperature, control the microwave generator 10 to operate at the second microwave power to perform the second heating stage on the shelled food. The second microwave power is less than the first microwave power.

[0048] In this way, by monitoring the surface temperature of the shelled food, the state of the shelled food during the heating process can be determined, and the microwave power of the microwave generator 10 for heating the shelled food can be continuously adjusted according to the surface temperature. This can prevent the rapid generation of a large amount of steam inside the shelled food in a short period of time during the heating process, thereby avoiding the explosion of the shelled food during the heating process to a certain extent.

[0049] The microwave cooking appliance 100 can be a microwave oven, a microwave oven-oven combination, or a microwave steam oven combination, or other devices that use microwaves to heat food. The microwave cooking appliance 100 described in this application is an example of a microwave oven.

[0050] The microwave cooking appliance 100 includes a microwave generator 10 and a cooking cavity 20. The microwave generator 10 includes, but is not limited to, a magnetron, a solid-state generator, and a radio frequency module. After the food is placed in the cooking cavity 20, microwaves are emitted from the microwave generator 10 onto the food, and the food is heated by the microwave energy.

[0051] For example, a microwave cooking appliance 100 may include a power supply, a cooking cavity 20, and an electrical compartment, while a microwave generator 10 may include a magnetron and a frequency converter. During operation, the frequency converter in the electrical compartment controls different output powers by changing the power supply frequency, which are supplied to the magnetron in the electrical compartment. The magnetron continuously generates microwaves, which are then transmitted through a waveguide and a stirring antenna in the electrical compartment to the cooking cavity 20, heating the food inside the cooking cavity 20.

[0052] The microwave cooking appliance 100 is equipped with a control device 200 for controlling the heating of shelled food. The control device 200 includes a processor 210, a memory 220, and a computer program 221. The computer program 221 is stored in the memory 220 and executed by the processor 210. The computer program 221 includes steps for performing a control method for heating shelled food.

[0053] Specifically, when food with shells is placed in the cooking cavity 20 of the microwave cooking appliance 100 for heating, the processor 210 can determine the first microwave power for heating the food with shells in the first heating stage based on the initial surface temperature of the food with shells and the cavity temperature of the cooking cavity 20. For example, as Figure 3 As shown, the first heating stage can be a [0, Ta] heating stage, and the first microwave power of the first heating stage [0, Ta] can be P0. It should be noted that the shelled food can be eggs, duck eggs, or other egg-based foods. The initial surface temperature of the shelled food refers to the surface temperature of the shell when the shelled food is placed in the cooking cavity 20 without being heated. For example, when the shelled food is placed in a natural environment, the initial surface temperature is 20 degrees Celsius; when the shelled food is placed in a freezer or other freezing environment, the initial surface temperature is 5 degrees Celsius. The first heating stage is the time period required to heat the shelled food to a first set temperature based on its surface temperature. The first set temperature is a temperature preset in the memory 220 of the microwave cooking appliance 100.

[0054] The processor 210 acquires the initial surface temperature of the shelled food and the cavity temperature of the cooking cavity 20 by installing a temperature sensor 30 in the microwave cooking appliance 100. When the shelled food is placed in the cooking cavity 20 and the microwave cooking appliance 100 is powered on, the temperature sensor 30 can collect the initial surface temperature of the shelled food and the cavity temperature of the cooking cavity 20. Based on the comparison between the collected initial surface temperature and cavity temperature and the temperature-power table pre-set in the memory 220 of the microwave cooking appliance 100, the processor 210 can obtain the first microwave power for the first heating stage. When there are multiple shelled foods, the highest surface temperature of the shelled food is collected as the initial surface temperature.

[0055] When the surface temperature of the shelled food reaches a first set temperature after being heated by the first microwave power, the processor 210 can control the microwave generator 10 to reduce the heating power and heat the shelled food with a second microwave power to perform a second heating stage. The second microwave power is less than the first microwave power. Therefore, compared to the prior art where heating shelled food with the same power can easily lead to an explosion, by changing the first microwave power of the microwave generator 10 to the second microwave power, the rate at which the shelled food generates steam can be reduced, thus preventing the generation of a large amount of steam in a short time and avoiding an explosion. For example, as... Figure 3 As shown, the first set temperature can be Ta, the second heating stage can be the [Ta, Tt] heating stage, and the second microwave power of the second heating stage can be P1 or P2.

[0056] In some implementations, the first microwave power can be in the range of 300 watts to 600 watts. For example, the first microwave power can be any value among 300 watts, 350 watts, 400 watts, 450 watts, 500 watts, 550 watts, 600 watts, or any value among 300 watts to 600 watts.

[0057] The first set temperature range is 45 degrees Celsius to 60 degrees Celsius. For example, the first set temperature can be any value of 45 degrees Celsius, 48 ​​degrees Celsius, 50 degrees Celsius, 55 degrees Celsius, 60 degrees Celsius, or any value of 45 degrees Celsius to 60 degrees Celsius.

[0058] The second microwave power is between 50 watts and 200 watts. For example, the second microwave power can be any value between 50 watts, 80 watts, 100 watts, 120 watts, 150 watts, 180 watts, 200 watts, or between 50 watts and 200 watts.

[0059] Thus, by setting the microwave power of the microwave generator 10 to 300 watts to 600 watts, heating efficiency can be improved while preventing the shelled food from exploding. When the surface temperature of the shelled food reaches 45 to 60 degrees Celsius, adjusting the power of the microwave generator 10 can prevent the temperature from becoming too high and generating a large amount of steam inside the shell in a short time. By adjusting the power of the microwave generator 10 to 50 to 200 watts, the shelled food can be heated while preventing the generation of a large amount of steam inside the shelled food in a short time, thereby preventing the shelled food from exploding.

[0060] Please see Figure 5 and Figure 6 In some embodiments, step 012: when the surface temperature of the shelled food reaches a first set temperature, controlling the microwave generator 10 to operate at a second microwave power to perform a second heating stage on the shelled food includes:

[0061] Step 0121: When the surface temperature of the shelled food reaches the first set temperature, control the microwave generator 10 to stop working for a preset time and then work at the second microwave power.

[0062] In this way, by controlling the microwave generator 10 to stop working after the surface temperature of the shelled food reaches a certain level, and then resuming work after the preset food, the temperature of the shelled food can be lowered during the period when the microwave generator 10 is not working, thus preventing the generation of a large amount of steam inside the shelled food in a short period of time, thereby preventing the shelled food from exploding.

[0063] Specifically, such as Figure 5 As shown, when the surface temperature of the shelled food reaches a first set temperature after being heated by the first microwave power, the processor 210 can control the microwave generator 10 to stop working for a preset time before heating the shelled food with the second microwave power to execute the second heating stage. The second microwave power is less than the first microwave power. Therefore, compared to the prior art where heating shelled food with the same power can easily cause an explosion, by heating the shelled food with the first microwave power to the first preset temperature and then stopping heating, the temperature of the shelled food is maintained at or lowered from the first preset temperature. This reduces the rate at which the shelled food generates steam, preventing the generation of a large amount of steam in a short time and thus avoiding an explosion. Then, after the preset heating time has elapsed, the processor 210 controls the microwave generator 10 to heat with the second microwave power, allowing the shelled food to enter the second heating stage and continue heating until cooked. For example, as... Figure 6 As shown, the first heating stage can be the [0, Ta] heating stage, the first microwave power of the first heating stage [0, Ta] can be P0, the preset duration can be t1, and the first set temperature can be Ta. The second heating stage can be the [Ta, Tt] heating stage, and the second microwave power of the second heating stage can be P1 or P2.

[0064] In some implementations, the preset duration ranges from 3 seconds to 15 seconds. For example, the preset duration can be any value between 3 seconds, 5 seconds, 7 seconds, 9 seconds, 11 seconds, 13 seconds, 15 seconds, or 3 seconds to 15 seconds.

[0065] Thus, by setting the preset duration for which the microwave generator 10 stops working to a range of 3 to 15 seconds, the temperature of the shelled food can be reduced to a temperature that will not explode. When the preset duration for which the microwave generator 10 stops working is less than 3 seconds, the temperature of the shelled food drops too little, which may easily cause an explosion. When the preset duration for which the microwave generator 10 stops working is greater than 15 seconds, the temperature of the shelled food drops too much, which prolongs the heating time and reduces the heating efficiency.

[0066] Please see Figure 6 and Figure 7 In some embodiments, step 012: when the surface temperature of the shelled food reaches a first set temperature, controlling the microwave generator 10 to operate at a second microwave power to perform a second heating stage on the shelled food includes:

[0067] Step 0122: When the surface temperature of the shelled food reaches the first set temperature, control the microwave generator 10 to operate at the second microwave power to perform at least two second heating stages on the shelled food.

[0068] Thus, when the surface temperature of the shelled food reaches the preset value, by heating the shelled food in multiple heating stages and adjusting the power of the microwave generator 10 during the switching of heating stages, the microwave generator 10 can maintain a relatively low heating power to heat the shelled food during the heating process, avoiding the generation of a large amount of steam inside the shelled food in a short period of time, thereby preventing the shelled food from exploding.

[0069] Specifically, after heating the surface temperature of the shelled food to a first set temperature using the first microwave power, the processor 210 can control the microwave generator 10 to heat the shelled food with a second microwave power to perform at least two second heating stages. Multiple second heating stages can be preset in the memory 220 of the microwave cooking appliance 100, and the specific number of second heating stages can be selected according to user instructions. Multiple second heating stages can reduce the efficiency of steam generation inside the shelled food, preventing the shelled food from exploding due to excessive steam generation in a short period.

[0070] Among them, such as Figure 6 As shown, the second heating stage may include multiple heating stages, which are not limited here, and the second microwave power is different for each heating stage. For example, as Figure 5 As shown, the second heating stage may include two heating stages [Ta, tb] and [Tb, Tt], and the second microwave power P1 of the heating stage [Ta, tb] is greater than the second microwave power P2 of the heating stage [Tb, Tt].

[0071] Please see Figure 6In some embodiments, step 0122: when the surface temperature of the shelled food reaches a first set temperature, the microwave generator 10 is controlled to operate at a second microwave power to perform at least two second heating stages on the shelled food. This includes, during the execution of the previous second heating stage, when the surface temperature of the shelled food reaches a second set temperature, the microwave generator 10 is controlled to operate at a second microwave power to perform a next second heating stage on the shelled food. The second set temperature is greater than the first set temperature, and the second set temperature of the next second heating stage is greater than the second set temperature of the previous second heating stage.

[0072] Thus, by controlling the microwave generator 10 to operate at a second microwave power to perform the next second heating stage on the shelled food, and the second set temperature of the next second heating stage is greater than the second set temperature of the previous second heating stage, the temperature of the shelled food can be increased while preventing the shelled food from exploding.

[0073] Specifically, based on user instructions, the processor 210 can determine the number of second heating stages. During the execution of the previous second heating stage, if the processor 210 detects that the surface temperature of the shelled food has reached a second set temperature, the processor 210 can control the microwave generator 10 to operate at a second microwave power to heat the shelled food, thus executing the next second heating stage. The second set temperature is greater than the first set temperature, and the second set temperature of the next second heating stage is greater than the second set temperature of the previous second heating stage.

[0074] For example, such as Figure 6 As shown, according to the user's instructions, the processor 210 can determine that the number of second heating stages is two. When the first second heating stage [Ta, tb] is heated to the second set temperature Tb of the first second heating stage [Ta, tb] with the second microwave power P1, the processor 210 controls the microwave generator 10 to heat to the second set temperature Tt of the next second heating stage [Tb, Tt] with the second microwave power P2. The second set temperature Tb of the first second heating stage is less than the second set temperature Tt of the second second heating stage.

[0075] In some implementations, the second set temperature ranges from 65 degrees Celsius to 75 degrees Celsius. For example, the second set temperature can be any value among 65 degrees Celsius, 67 degrees Celsius, 69 degrees Celsius, 71 degrees Celsius, 73 degrees Celsius, 75 degrees Celsius, or any value among 65 degrees Celsius and 75 degrees Celsius.

[0076] Thus, when the surface temperature of the shelled food reaches 65 to 75 degrees Celsius, the shelled food is almost cooked through. By adjusting the power of the microwave generator 10, the shelled food can be prevented from being overheated, resulting in nutrient loss and affecting the taste.

[0077] Please see Figure 8 In some embodiments, during the execution of the previous second heating stage, when the surface temperature of the shelled food reaches the second set temperature, the microwave generator 10 is controlled to operate at the second microwave power to execute the next second heating stage on the shelled food. This includes controlling the microwave generator 10 to stop operating for a preset time after the surface temperature of the shelled food reaches the second set temperature during the execution of the previous second heating stage before executing the next second heating stage.

[0078] In this way, by controlling the microwave generator 10 to stop working after the surface temperature of the shelled food reaches a certain level, and then resuming work after the preset food, the temperature of the shelled food can be lowered during the period when the microwave generator 10 is not working, thus preventing the generation of a large amount of steam inside the shelled food in a short period of time, thereby preventing the shelled food from exploding.

[0079] Specifically, during the execution of the previous second heating stage, when the surface temperature of the shelled food reaches the second set temperature, the processor 210 can control the microwave generator 10 to stop working for a preset time before executing the next second heating stage.

[0080] For example, such as Figure 8 As shown, after the processor 210 completes the first second heating stage [Ta, tb] with the second microwave power P1, raising the surface temperature of the shelled food to the second set temperature Tb of the first second heating stage [Ta, tb], the processor 210 can control the microwave generator 10 to stop working for a preset time, so that the surface temperature of the shelled food is maintained at the second set temperature Tb or lowered below the second set temperature Tb. Then, the processor 210 controls the microwave generator 10 to heat the food to the second set temperature Tt with the second microwave power P2 of the next second heating stage [Tb, Tt].

[0081] Please see Figure 6 and Figure 9 In some embodiments, after step 012: controlling the microwave generator 10 to operate at a second microwave power to perform a second heating stage on the shelled food, the control method includes:

[0082] Step 013: When the microwave generator 10 heats the shelled food to the third set temperature at the second microwave power, control the microwave generator 10 to turn off so that the shell of the shelled food remains intact.

[0083] Thus, when the microwave generator 10 heats the shelled food to the third set temperature at the second microwave power, the microwave generator 10 is turned off. At this time, the shelled food is fully cooked. By turning off the microwave generator 10, the shelled food can be prevented from being overheated, thus avoiding nutrient loss and affecting the taste.

[0084] Specifically, when the microwave generator 10 heats the shelled food to a third set temperature at a second microwave power, the shelled food has already been microwave-cooked, and the processor 210 can control the microwave generator 10 to shut down so that the shell of the food remains intact. For example, as... Figure 6 As shown, the third set temperature can be Tt. After the second microwave power P2 of the second heating stage [Tb, Tt] heats the microwave generator 10 to the third set temperature Tt, the processor 210 can control the microwave generator 10 to stop working.

[0085] In some implementations, the third set temperature ranges from 75 degrees Celsius to 82 degrees Celsius. For example, the third set temperature can be any value among 75 degrees Celsius, 76 degrees Celsius, 77 degrees Celsius, 78 degrees Celsius, 79 degrees Celsius, 82 degrees Celsius, or 75 degrees Celsius and 82 degrees Celsius.

[0086] Thus, by heating shelled food to between 75 and 82 degrees Celsius, it can be determined that the shelled food is fully cooked and does not need to be heated further, thereby saving energy consumption and reducing costs.

[0087] Please see Figure 10 The present invention also provides a computer-readable storage medium 300 storing a computer program 221. When the computer program 221 is executed by the processor 210, it implements the steps of the control method for heating shelled food in any of the above embodiments. For the sake of brevity, these steps will not be described in detail here.
