[0013] In one embodiment, during the same boiling period, the heating power of the heater corresponding to the case where the temperature of the target fluid is greater than the corresponding preset temperature is less than the heating power of the heater corresponding to the case where the temperature of the target fluid is less than or equal to the corresponding preset temperature.

[0014] And / or, during the same boiling period, the heating power of the heater corresponding to the case where the temperature change rate of the target fluid is greater than the corresponding preset temperature change rate is less than the heating power of the heater corresponding to the case where the temperature change rate of the target fluid is less than or equal to the corresponding preset temperature change rate.

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0053] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this application will not be described separately.

[0054] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0055] In related technologies, cooking appliances cook food within a cooking cavity. During the cooking process, the gas inside the cooking cavity is essentially not released, making it difficult to achieve sustained boiling. As a result, the food is overcooked, affecting its texture. However, for some foods, it is necessary for the cooking cavity to continuously boil during the cooking process to achieve a better texture.

[0056] Therefore, this application provides a cooking appliance; please refer to the embodiments provided. Figure 1 The cooking appliance includes a cooking body 1 and a pressure relief valve 2. The cooking body 1 has a cooking cavity 11 for cooking food and an exhaust channel 12 for communicating with the cooking cavity 11 to discharge gas from the cooking cavity 11. The pressure relief valve 2 is located at the exhaust channel 12. When the pressure relief valve 2 is in a closed state, it cuts off the exhaust channel 12 from the cooking cavity 11, and the steam is basically sealed inside the cooking cavity 11. When the pressure relief valve 2 is in an open state, it communicates with the exhaust channel 12 from the cooking cavity 11, and the steam is discharged from the cooking cavity 11 into the exhaust channel 12 and then discharged to the outside of the cooking appliance.

[0057] Pressure relief valve 2 is a device to relieve excessive pressure in the cooking chamber 11 of the cooking appliance. When the pressure in the cooking chamber 11 of the cooking appliance is greater than or equal to the pressure relief valve 2, the pressure relief valve 2 is opened by the steam in the cooking chamber 11, and the steam in the cooking chamber 11 can flow out from the cooking chamber 11 through the pressure relief valve 2. When the pressure in the cooking chamber 11 of the cooking appliance is less than the pressure relief valve 2, the pressure relief valve 2 is closed.

[0058] For example, please refer to Figure 1 The temperature measuring device 3 is installed in the exhaust channel 12 to measure the temperature of the steam discharged from the cooking chamber 11 to the exhaust channel 12 via the pressure limiting valve 2. When the pressure limiting valve 2 is open, the steam generated by boiling in the cooking chamber 11 is discharged to the exhaust channel 12 via the pressure limiting valve 2 and flows through the temperature measuring device 3 in the exhaust channel 12 before being discharged to the outside of the cooking appliance.

[0059] For example, the pressure relief valve 2 is closed by its own weight to cut off the cooking chamber 11 from the exhaust passage 12. When the cooking chamber 11 boils, the steam pressure inside the cooking chamber 11 overcomes the weight of the pressure relief valve 2, causing the pressure relief valve 2 to open, thereby allowing the steam inside the cooking chamber 11 to push open the pressure relief valve 2.

[0060] For example, the temperature measuring device 3 can be a temperature sensor.

[0061] This application provides a cooking method, which includes:

[0062] Step S1: Adjust the heating power of the heater to keep the cooking chamber of the cooking appliance boiling, at least with the pressure relief valve in the open position. The heater is used to heat the cooking chamber.

[0063] It should be noted that the main point here is to maintain boiling, not to maintain it at a specific boiling point.

[0064] In this embodiment of the application, during the food cooking process, the pressure limiting valve 2 is opened, and the steam in the cooking chamber 11 is discharged from the pressure limiting valve 2, so that the cooking chamber 11 can boil well. By adjusting the power at least when the pressure limiting valve 2 is open, the cooking chamber 11 can maintain boiling. The boiling in the cooking chamber 11 can be sustained to a certain extent, which can also alleviate the excessive boiling in the cooking chamber 11.

[0065] In one embodiment, adjusting the heating power of the heater to maintain boiling in the cooking chamber 11 of the cooking appliance, at least when the pressure relief valve 2 is in the open state, includes:

[0066] Step S2: When the pressure relief valve remains open during the boiling cycle, adjust the heating power of the heater according to the temperature of the target fluid to maintain the corresponding boiling level in the cooking chamber of the cooking appliance. The target fluid is the steam discharged from the cooking chamber through the pressure relief valve.

[0067] The degree of boiling, or the intensity of boiling, varies. In some cases, the boiling in the cooking chamber 11 is more intense, producing a larger amount of steam. In other cases, the boiling in the cooking chamber 11 is slight, producing a smaller amount of steam.

[0068] The pressure relief valve 2 remains open during the boiling cycle. During the boiling cycle, the pressure relief valve 2 is pushed open by the steam in the cooking chamber 11 and will not close. Steam continues to flow out of the cooking chamber 11 through the pressure relief valve 2.

[0069] The target fluid refers to the fluid flowing out of the cooking chamber 11 through the pressure relief valve 2. For cooking food in a boiling state, the target fluid is mainly steam.

[0070] The temperature of the target fluid is measured by the temperature measuring device 3 corresponding to the exhaust channel 12 of the pressure limiting valve 2. The temperature of the target fluid is affected by steam. When the pressure limiting valve 2 is closed, the steam is confined within the cooking chamber 11, and no target fluid flows out of the pressure limiting valve 2. The temperature measured by the temperature measuring device 3 corresponding to the exhaust channel 12 of the pressure limiting valve 2 is close to the ambient temperature. When the pressure limiting valve 2 is open, the target fluid flows out of the cooking chamber 11 through the pressure limiting valve 2, and the temperature measured by the temperature measuring device 3 corresponding to the exhaust channel 12 of the pressure limiting valve 2 is higher. The temperature of the target fluid is related to the amount of steam discharged from the pressure limiting valve 2. The greater the amount of steam, the more heat is transferred to the temperature measuring device 3 corresponding to the exhaust channel 12 of the pressure limiting valve 2, resulting in a higher temperature measured by the sensor. The amount of steam is also related to the boiling degree within the cooking chamber 11. The greater the boiling degree, the greater the amount of steam discharged from the pressure limiting valve 2; the lower the boiling degree, the smaller the amount of steam discharged from the pressure limiting valve 2. The temperature of the target fluid effectively reflects the boiling degree within the cooking chamber 11.

[0071] For example, the temperature of the target fluid is greater than or equal to 50°C.

[0072] Step S3: When the pressure relief valve switches between the open and closed states during the boiling cycle, adjust the heating power of the heater according to the state of the pressure relief valve to maintain boiling in the cooking chamber.

[0073] The pressure relief valve 2 switches between open and closed states, resulting in significant differences in boiling intensity even within the same boiling period. The primary purpose of maintaining the cooking chamber 11 at a boiling state is to use the state of the pressure relief valve 2 as a reference.

[0074] There are several ways to determine the state of pressure relief valve 2. For example, it can be triggered by an electrical signal indicating whether pressure relief valve 2 is open or closed. Another method is to determine the open or closed state of pressure relief valve 2 by measuring the pressure inside the cooking chamber 11. If the pressure inside the cooking chamber 11 is less than the pressure relief valve 2's limit value, pressure relief valve 2 is closed; if the pressure inside the cooking chamber 11 is less than or equal to the pressure relief valve 2's limit value, pressure relief valve 2 is open. For instance, when pressure relief valve 2 is closed, steam is confined within the cooking chamber 11, and there is almost no steam at the exhaust channel 12 of pressure relief valve 2. The temperature measured by the temperature measuring device 3 at the exhaust channel 12 of pressure relief valve 2 is close to the ambient temperature. When pressure relief valve 2 is open, the target fluid flows out of the cooking chamber 11 through the exhaust channel 12 of pressure relief valve 2. The temperature of the target fluid measured by the temperature measuring device 3 at the exhaust channel 12 of pressure relief valve 2 is close to the steam temperature. Since the target fluid temperature is relatively high, the state of pressure relief valve 2 can also be determined by the temperature of the target fluid.

[0075] For example, when the temperature measured by the temperature measuring device 3 at the exhaust channel 12 of the pressure relief valve 2 is close to the ambient temperature, the pressure relief valve 2 is in the closed state; when the temperature measured by the temperature measuring device 3 at the exhaust channel 12 of the pressure relief valve 2 is greater than or equal to 50°C, the pressure relief valve 2 is in the open state.

[0076] In this embodiment, the specific power adjustment method for different situations is defined, at least when the pressure relief valve 2 is in the open state. When the pressure relief valve 2 remains in the open state during the boiling cycle, different boiling degrees correspond to different temperatures of the target fluid discharged from the cooking chamber 11 through the pressure relief valve 2. Different temperatures of the target fluid correspond to different boiling degrees. By adjusting the heater power at different target fluid temperatures, the cooking chamber 11 is kept in a state of approximately continuous boiling, and the boiling degree is approximately similar. When the pressure relief valve 2 switches between the open and closed states during the boiling cycle, the state of the pressure relief valve 2 can reflect the boiling state in the cooking chamber 11 to a certain extent. Adjusting the heating power according to the state of the pressure relief valve 2 can better maintain the boiling state in the cooking chamber 11.

[0077] In one embodiment, please refer to Figure 2 When the pressure relief valve 2 remains open during the boiling cycle, the heating power of the heater is adjusted according to the temperature of the target fluid to maintain the cooking chamber 11 of the cooking appliance at a corresponding boiling level, including:

[0078] Step S4: Determine the preset parameters corresponding to the boiling degree in the cooking chamber based on the boiling period within each boiling cycle. The preset parameters include preset temperature and / or preset temperature change rate.

[0079] The more intense the boiling, the greater the amount of steam in the exhaust channel 12 of the pressure relief valve 2, and the higher the temperature of the target fluid measured by the temperature measuring device 3 at the exhaust channel 12 of the pressure relief valve 2. Correspondingly, the temperature measuring device 3 has a faster temperature rise.

[0080] The preset temperature and preset temperature change rate were obtained experimentally based on the amount of food. The goal is to minimize overflow caused by boiling within the cooking cavity 11 while ensuring the food is boiling.

[0081] The degree of boiling varies depending on the different boiling periods within each boiling cycle.

[0082] For example, the duration of each boiling period can be determined based on the amount of food, cooking function, and cooking stage.

[0083] For example, the duration of each boiling period can be set by the user according to actual needs.

[0084] For example, the duration of each boiling period within the same boiling cycle can be equal or unequal.

[0085] The preset temperature change rate is the preset temperature change rate.

[0086] For example, the preset temperature is determined by the amount of food, the cooking function, and the cooking stage.

[0087] For example, the correspondence between preset temperature and food quantity, cooking function and cooking stage can be determined experimentally.

[0088] For example, the preset temperature can be set by the user according to actual needs.

[0089] For example, the preset temperature change rate is determined by the amount of food, cooking function, and cooking stage.

[0090] For example, the correspondence between the preset temperature change rate and the amount of food, cooking function, and cooking stage can be determined experimentally.

[0091] For example, the preset temperature change rate can be set by the user according to actual needs.

[0092] For example, the amount of food can be determined by the time required to heat the food to a specific temperature.

[0093] For example, by measuring the temperature change of the target fluid over a period of time through the temperature measuring device 3 at the exhaust channel 12 of the pressure relief valve 2, the temperature change rate of the target fluid can be obtained.

[0094] The more violently the boiling occurs in the cooking chamber 11, the greater the amount of steam discharged from the exhaust channel 12 of the pressure relief valve 2, and the faster the heat can be transferred to the temperature measuring device 3, resulting in a greater rate of temperature change of the target fluid.

[0095] A boiling period refers to a time segment within a boiling cycle. For example, if each boiling cycle is 60 seconds and each boiling period is 20 seconds, there are three boiling periods in each boiling cycle: the first boiling period is from 0 to 20 seconds, the second boiling period is from 20 to 40 seconds, and the third boiling period is from 40 to 60 seconds.

[0096] Step S5: Determine the heating power based on the temperature of the target fluid and the preset parameters to maintain the cooking chamber at the corresponding boiling level.

[0097] Different target fluid temperatures correspond to different boiling levels, and the heating power of the cooking chamber 11 will also differ depending on the boiling level.

[0098] The preset temperature and / or the rate of change of preset temperature corresponding to different boiling periods characterize the degree of boiling that needs to be basically maintained during that boiling period.

[0099] For example, when the temperature of the target fluid is less than or equal to the preset temperature of the corresponding boiling period, the boiling degree in the cooking chamber 11 deviates from the boiling degree of the corresponding boiling period. By using higher heating power to bring the temperature of the target fluid as close as possible to the preset temperature, the cooking chamber 11 is maintained at the corresponding boiling degree. When the temperature of the target fluid is greater than the preset temperature of the corresponding boiling period, the boiling degree in the cooking chamber 11 deviates from the boiling degree of the corresponding boiling period. By using lower heating power to lower the temperature of the target fluid as close as possible to the preset temperature, the cooking chamber 11 is maintained at the corresponding boiling degree.

[0100] For example, when the temperature change rate of the target fluid is less than or equal to the preset temperature change rate for the corresponding boiling period, the boiling level in the cooking chamber 11 deviates from the boiling level for the corresponding boiling period. By using a higher heating power to increase the temperature change rate of the target fluid to approach the preset temperature change rate as closely as possible, the cooking chamber 11 is maintained at the corresponding boiling level. When the temperature change rate of the target fluid is greater than the preset temperature change rate for the corresponding boiling period, the boiling level in the cooking chamber 11 deviates from the boiling level for the corresponding boiling period. By using a lower heating power to decrease the temperature change rate of the target fluid to approach the preset temperature change rate as closely as possible, the cooking chamber 11 is maintained at the corresponding boiling level.

[0101] In this embodiment, the preset parameters for the corresponding boiling degree can be determined by the boiling period. By using the temperature of the target fluid and the preset parameters corresponding to different boiling degrees, the deviation of the boiling degree within the cooking chamber 11 can be determined, thereby enabling a more accurate determination of the heating power so that the cooking chamber 11 can be maintained at the corresponding boiling degree as much as possible.

[0102] In one embodiment, please refer to Figure 2 and Figure 4 During the same boiling period, the heating power of the heater corresponding to the case where the temperature of the target fluid is greater than the corresponding preset temperature is less than the heating power of the heater corresponding to the case where the temperature of the target fluid is less than or equal to the corresponding preset temperature.

[0103] Within the same boiling period, the preset temperature is fixed. If the temperature of the target fluid is less than or equal to the preset temperature, the boiling degree in the cooking chamber 11 is not reached for the corresponding boiling period. If the temperature of the target fluid is greater than the preset temperature, the boiling degree in the cooking chamber 11 for the corresponding period is too high.

[0104] The heating power of the heater corresponding to the target fluid temperature being greater than the corresponding preset temperature is less than the heating power of the heater corresponding to the target fluid temperature being less than or equal to the corresponding preset temperature. This means that the heating power of the heater corresponding to the target fluid temperature being greater than the corresponding preset temperature is smaller, and the heating power of the heater corresponding to the target fluid temperature being less than or equal to the corresponding preset temperature is larger.

[0105] Maintaining the boiling level does not mean that the boiling level within the cooking chamber 11 remains completely constant, but rather that the boiling level within the cooking chamber 11 fluctuates within a certain range around the corresponding boiling level during the corresponding boiling period. Specifically, this manifests as the temperature of the target fluid fluctuating within a certain range around a preset temperature, or the rate of change of the target fluid's temperature fluctuating within a certain range around a preset rate of change of temperature.

[0106] In this embodiment, when the temperature of the target fluid is greater than the corresponding preset temperature, the boiling degree within the cooking chamber 11 during the corresponding boiling period is too high. The cooking chamber 11 is heated with lower power to appropriately reduce its temperature to approach the preset temperature, thereby maintaining the boiling degree during the corresponding boiling period. When the temperature of the target fluid is less than or equal to the corresponding preset temperature, the boiling degree within the cooking chamber 11 during the corresponding boiling period is insufficient. The cooking chamber 11 is heated with higher power to appropriately increase its temperature to approach the preset temperature, thereby maintaining the boiling degree during the corresponding boiling period, and the cooking chamber 11 boils almost continuously.

[0107] In one embodiment, please refer to Figure 2 and Figure 4 During the same boiling period, the heating power of the heater corresponding to the case where the temperature change rate of the target fluid is greater than the corresponding preset temperature change rate is less than the heating power of the heater corresponding to the case where the temperature change rate of the target fluid is less than or equal to the corresponding preset temperature change rate.

[0108] Within the same boiling period, the preset temperature change rate is fixed. If the temperature change rate of the target fluid is less than or equal to the preset temperature change rate, the boiling degree in the cooking chamber 11 is not reached for the corresponding boiling period. If the temperature change rate of the target fluid is greater than the preset temperature change rate, the boiling degree in the corresponding period in the cooking chamber 11 is too high.

[0109] The heating power of the heater corresponding to the condition where the temperature change rate of the target fluid is greater than the corresponding preset temperature change rate is less than the heating power of the heater corresponding to the condition where the temperature change rate of the target fluid is less than or equal to the corresponding preset temperature change rate. This means that the heating power of the heater corresponding to the condition where the temperature change rate of the target fluid is greater than the corresponding preset temperature change rate is relatively small, and the heating power of the heater corresponding to the condition where the temperature change rate of the target fluid is less than or equal to the corresponding preset temperature change rate is relatively large.

[0110] In this embodiment, when the temperature change rate of the target fluid is greater than the corresponding preset temperature change rate, the boiling degree within the cooking chamber 11 during the corresponding boiling period is too high. Heating the cooking chamber 11 with lower power appropriately reduces the temperature change rate of the cooking chamber 11 to approach the preset temperature change rate, thereby maintaining the boiling degree during the corresponding boiling period. When the temperature change rate of the target fluid is less than or equal to the corresponding preset temperature change rate, the boiling degree within the cooking chamber 11 during the corresponding boiling period is insufficient. Heating the cooking chamber 11 with higher power appropriately increases the temperature change rate of the cooking chamber 11 to approach the preset temperature change rate, thereby maintaining the boiling degree during the corresponding boiling period, and the cooking chamber 11 boils almost continuously.

[0111] In one embodiment, when the cooking appliance cooks the food in the cooking chamber 11 and enters the boiling stage, the cooking chamber 11 is in a boiling state. The entire boiling stage of cooking the food may include one or at least two boiling cycles. By controlling the boiling in each boiling cycle, the entire boiling stage is made to continue boiling.

[0112] In one embodiment, please refer to Figure 2 and Figure 4 There are multiple boiling periods within each boiling cycle, and each boiling period corresponds to a boiling degree and a preset parameter corresponding to the boiling degree.

[0113] Each boiling period within a boiling cycle has a corresponding preset parameter, which characterizes the boiling degree of that boiling period. For example, each boiling period within a boiling cycle has a corresponding preset temperature, which characterizes the boiling degree of that boiling period. Similarly, each boiling period within a boiling cycle has a corresponding preset temperature change rate, which characterizes the boiling degree of that boiling period.

[0114] In one embodiment, please refer to Figure 2 In two adjacent boiling periods, the preset temperature of the later boiling period is lower than the preset temperature of the earlier boiling period.

[0115] For example, within each boiling cycle, the preset temperature decreases sequentially from the first boiling period to the last boiling period.

[0116] For example, there are three boiling periods in each boiling cycle, the preset temperature of the second boiling period is lower than the preset temperature of the first boiling period, and the preset temperature of the third boiling period is lower than the preset temperature of the second boiling period.

[0117] For example, each boiling cycle is 60 seconds, the first boiling cycle is 0 to 20 seconds, the second boiling cycle is 20 to 40 seconds, and the third boiling cycle is 40 to 60 seconds.

[0118] In this embodiment, the preset temperature of the later boiling period is lower than the preset temperature of the previous boiling period, that is, the boiling degree of the previous boiling period is more intense than the boiling degree of the later boiling period. This boiling method makes the boiling degree of each boiling period in each boiling cycle decrease gradually. By using different boiling degrees in each boiling period, the food can be cooked better, and it is easy to end the boiling at a lower boiling degree.

[0119] In one embodiment, please refer to Figure 2 The rate of change of the preset temperature in the later boiling period is less than the rate of change of the preset temperature in the earlier boiling period.

[0120] For example, within each boiling cycle, from the first boiling period to the last boiling period, the corresponding preset temperature change rate decreases period by period.

[0121] For example, there are three boiling periods in each boiling cycle, the preset temperature change rate of the second boiling period is lower than the preset temperature change rate of the first boiling period, and the preset temperature change rate of the third boiling period is lower than the preset temperature change rate of the second boiling period.

[0122] In this embodiment, the preset temperature change rate of the later boiling period is less than the preset temperature change rate of the earlier boiling period. That is, the boiling degree of the earlier boiling period is more intense than the boiling degree of the later boiling period. This boiling method makes the boiling degree of each boiling period in each boiling cycle decrease gradually. By using different boiling degrees in each boiling period, the food can be cooked better, and it is easy to end the boiling at a lower boiling degree.

[0123] In one embodiment, please refer to Figure 2The earliest boiling period within each boiling cycle is the first boiling period, the preset temperature corresponding to the first boiling period is the first preset temperature, and the rate of change of the preset temperature corresponding to the first boiling period is the first preset temperature change rate. The heating power is determined based on the temperature of the target fluid and the preset parameters to maintain the cooking chamber 11 at a corresponding boiling level, including:

[0124] Step S6: During the first boiling period, when the temperature of the target fluid is less than or equal to the first preset temperature and / or the rate of change of the temperature of the target fluid is less than or equal to the first preset temperature change rate, the cooking cavity is heated with the first power.

[0125] During the first boiling period, the preset temperature and / or preset temperature change rate correspond to the required boiling degree during the first boiling period.

[0126] When the temperature of the target fluid is less than or equal to the first preset temperature, the boiling degree in the cooking chamber 11 deviates from the boiling degree corresponding to the first boiling period, and the boiling degree in the cooking chamber 11 is smaller.

[0127] When the rate of change of the target fluid temperature is less than or equal to the first preset rate of change of temperature, the boiling degree in the cooking chamber 11 deviates from the boiling degree corresponding to the first boiling period, and the boiling degree in the cooking chamber 11 is smaller.

[0128] When the temperature of the target fluid is less than or equal to the first preset temperature and the rate of change of the target fluid temperature is less than or equal to the first preset temperature change rate, the boiling degree in the cooking chamber 11 deviates from the boiling degree corresponding to the first boiling period, and the boiling degree in the cooking chamber 11 is relatively small.

[0129] Step S7: During the first boiling period, when the temperature of the target fluid is greater than the first preset temperature and / or the rate of change of the temperature of the target fluid is greater than the rate of change of the first preset temperature, reduce the power of the heater.

[0130] When the temperature of the target fluid is greater than the first preset temperature, the boiling degree in the cooking chamber 11 deviates from the boiling degree corresponding to the first boiling period, and the boiling degree in the cooking chamber 11 is larger.

[0131] When the rate of change of the target fluid temperature is greater than the first preset rate of change of temperature, the boiling degree in the cooking chamber 11 deviates from the boiling degree corresponding to the first boiling period, and the boiling degree in the cooking chamber 11 is larger.

[0132] When the temperature of the target fluid is greater than the first preset temperature and / or the rate of change of the temperature of the target fluid is greater than the rate of change of the first preset temperature, the boiling degree in the cooking chamber 11 deviates from the boiling degree corresponding to the first boiling period, and the boiling degree in the cooking chamber 11 is relatively large.

[0133] In this embodiment, when the temperature of the target fluid is less than or equal to a first preset temperature and / or the rate of change of the target fluid's temperature is less than or equal to the first preset temperature rate of change, the boiling degree of the cooking chamber 11 is small, and the boiling degree of the cooking chamber 11 deviates from the boiling degree corresponding to the first boiling period. The cooking chamber 11 is heated by a larger first power, causing the temperature of the target fluid to rise to approach the preset temperature and / or causing the rate of change of the target fluid's temperature to rise to approach the preset temperature rate of change. When the temperature of the target fluid is greater than the first preset temperature and / or the rate of change of the target fluid's temperature is greater than the first preset temperature rate of change, the boiling degree of the cooking chamber 11 is large, and the boiling degree of the cooking chamber 11 deviates from the boiling degree corresponding to the first boiling period. The power of the heater is reduced to make the heater power lower than the first power to heat the cooking chamber 11, causing the temperature of the target fluid to drop to approach the preset temperature and / or causing the rate of change of the target fluid's temperature to drop to approach the preset temperature rate of change, thereby achieving the purpose of maintaining the cooking chamber 11 at the corresponding boiling degree.

[0134] In one embodiment, please refer to Figure 2 The latest boiling period within each boiling cycle is the second boiling period, the preset temperature corresponding to the second boiling period is the second preset temperature, and the rate of change of the preset temperature corresponding to the second boiling period is the second preset temperature change rate. Determining the heating power based on the temperature of the target fluid and the preset parameters to maintain the cooking chamber 11 at a corresponding boiling level also includes:

[0135] Step S8: During the second boiling period, when the temperature of the target fluid is less than or equal to the second preset temperature and / or the rate of change of the temperature of the target fluid is less than or equal to the first preset temperature change rate, the cooking cavity is heated with a second power, where the second power is less than the first power.

[0136] The second boiling period is the latest phase in the boiling cycle. The boiling intensity during the second boiling period is lower than that during the first boiling period, which is more vigorous. Because the boiling intensity is lower during the second boiling period, it can be maintained by heating with lower power.

[0137] Step S9: During the second boiling period, when the temperature of the target fluid is greater than the second preset temperature and / or the rate of change of the temperature of the target fluid is greater than the rate of change of the second preset temperature, reduce the power of the heater.

[0138] For example, reducing the power of the heater can be done by turning the heater off.

[0139] In this embodiment, when the temperature of the target fluid is less than or equal to a second preset temperature and / or the rate of change of the target fluid's temperature is less than or equal to a first preset temperature change rate, heating with a second power raises the temperature of the target fluid to the preset temperature and / or increases the rate of change of the target fluid's temperature to the preset temperature change rate. When the temperature of the target fluid is greater than the second preset temperature and / or the rate of change of the target fluid's temperature is greater than the second preset temperature change rate, the power of the heater is reduced to heat the cooking chamber 11 with a lower power than the second power, causing the temperature of the target fluid to drop to the preset temperature and / or the rate of change of the target fluid's temperature to decrease to the preset temperature change rate, thereby maintaining the boiling level within the cooking chamber 11. Since the boiling level is lower during the second boiling period, heating the cooking chamber 11 with a second power lower than the first power ensures that the cooking chamber 11 can be heated to the boiling level corresponding to the second boiling period, preventing excessively rapid heating within the cooking chamber 11 from causing excessively vigorous boiling.

[0140] In one embodiment, please refer to Figure 2 When the pressure relief valve 2 remains open during the boiling cycle, the heating power of the heater is adjusted according to the temperature of the target fluid to maintain the cooking chamber 11 of the cooking appliance at a corresponding boiling level, and the following is also included:

[0141] Step S10: Determine the corresponding boiling period based on the running time of each boiling cycle. The running time of the boiling cycle is the time between the current moment of the boiling cycle and the start moment of the boiling cycle.

[0142] Step S11: When the running time of the boiling cycle reaches the total duration of the boiling cycle, the running time of the boiling cycle is reset to zero.

[0143] The running time of the boiling cycle is the time between the current moment of the boiling cycle and the start moment of the boiling cycle, that is, the time taken from the start moment of the boiling cycle as the starting point of the timing.

[0144] For example, the total duration of the boiling cycle is determined by the amount of food, the cooking stage, and the cooking function.

[0145] For example, the total duration of the boiling cycle can be set by the user according to actual needs.

[0146] For example, the boiling cycle is 60 seconds, the starting time of the boiling cycle is time 0, and each boiling period is 30 seconds. The first boiling period is from 0 to 30 seconds, and the second boiling period is from 30 to 60 seconds.

[0147] In this embodiment of the application, when the running time of the boiling cycle reaches the total duration of the boiling cycle, that is, the cooking appliance has completed one boiling cycle, the running time of the boiling cycle is reset to zero so that the next boiling cycle can continue to be boiled.

[0148] In one embodiment, please refer to Figure 3 and Figure 5 During the same boiling period of each boiling cycle, the heating power of the heater when the pressure relief valve 2 is in the closed state is greater than the heating power of the heater when the pressure relief valve 2 is in the open state.

[0149] By adjusting the heating power between the closed and open states of the pressure-limiting valve 2, the heating power is regulated not only when the pressure-limiting valve 2 is open but also when it is closed. The power is adjusted based on the state of the pressure-limiting valve 2 to maintain boiling in the cooking chamber 11.

[0150] At the moment the pressure relief valve 2 closes, the cooking chamber 11 does not completely stop boiling, but the boiling level is low. With the pressure relief valve 2 closed, the heating of the cooking chamber 11 is switched to a higher power. After the pressure relief valve 2 closes, the low boiling level in the cooking chamber 11 will not continue to decrease, but the boiling level will be intensified under the heating of higher power, and the pressure relief valve 2 will be pushed open, so that the pressure relief valve 2 switches between the open and closed state, and the cooking chamber 11 continues to boil.

[0151] In this embodiment, during the same boiling period, when the pressure limiting valve 2 is closed, the boiling level in the cooking chamber 11 is low; when the pressure limiting valve 2 is open, it can be basically determined that the cooking chamber 11 is in a boiling state. The pressure limiting valve 2 is switched to an open state by heating with higher power when it is closed to induce boiling in the cooking chamber 11, and then heated with lower power when it is open to prevent excessive boiling in the cooking chamber 11. By adjusting the heating power of the pressure limiting valve 2 in the open and closed states, the pressure limiting valve 2 can repeatedly switch between these states, thereby maintaining a basic level of boiling in the cooking chamber 11 while preventing excessive boiling.

[0152] In one embodiment, please refer to Figure 3 The earliest boiling period within each boiling cycle is the first boiling period. When the pressure relief valve 2 switches between an open and closed state during the boiling cycle, the heating power of the heater is adjusted according to the state of the pressure relief valve 2 to maintain boiling in the cooking chamber 11, including:

[0153] Step S12: During the first boiling period, when the pressure relief valve is in the closed state, the cooking chamber is heated with the third power.

[0154] Step S13: During the first boiling period, when the pressure relief valve is in the open state, the cooking chamber is heated with a fourth power, the fourth power being less than or equal to the third power and greater than zero.

[0155] In this embodiment, a higher third power is used to heat the cooking chamber 11, causing it to boil and open the closed pressure-limiting valve 2. A lower fourth power is then used to heat the cooking chamber 11 to reduce boiling. This reduces the amount of steam and pressure in the cooking chamber 11, thus closing the open pressure-limiting valve 2 and achieving continuous boiling within the cooking chamber 11. The first boiling period is the most intense boiling phase within the boiling cycle. The fourth power is greater than zero and less than or equal to the third power, ensuring that regardless of whether the pressure-limiting valve 2 is closed or open, the cooking chamber 11 is heated with a power greater than zero, resulting in a relatively intense boiling process.

[0156] In one embodiment, please refer to Figure 3 The latest boiling period within each boiling cycle is the second boiling period. When the pressure relief valve 2 switches between open and closed states during the boiling cycle, the heating power of the heater is adjusted according to the state of the pressure relief valve 2 to maintain boiling in the cooking chamber 11. The method also includes:

[0157] Step S14: During the second boiling period, when the pressure relief valve is in the closed state, the cooking chamber is heated with a fifth power, the fifth power being less than or equal to the fourth power and greater than zero.

[0158] Step S15: During the second boiling period, when the pressure relief valve is in the open state, the heater is turned off.

[0159] When the heater is turned off, its power is 0. The fifth power is greater than zero, meaning the fifth power of the heater is greater than the power when the heater is turned off.

[0160] In this embodiment, the fifth power is less than or equal to the fourth power, resulting in a lower boiling degree in the cooking chamber 11 when the pressure-limiting valve 2 is closed during the second boiling period. When the pressure-limiting valve 2 is open during the second boiling period, the heater is turned off, resulting in almost no heating and a lower boiling degree in the cooking chamber 11. By ensuring the fifth power is less than or equal to the fourth power and the heater is turned off while the pressure-limiting valve 2 is open, the overall boiling degree of the cooking chamber 11 is more vigorous during the first boiling period and less vigorous during the second boiling period. This variation in boiling degree during cooking allows for better food preparation. The lower boiling degree during the latest second boiling period within the boiling cycle facilitates ending the cooking process at a lower boiling degree, preventing excessively vigorous boiling within the cooking chamber 11.

[0161] When the pressure relief valve 2 switches between an open and closed state during the boiling cycle, the heating power of the heater is adjusted according to the state of the pressure relief valve 2 to maintain boiling in the cooking chamber 11, including:

[0162] Step S16: Determine the corresponding boiling period based on the running time of each boiling cycle. The running time of the boiling cycle is the duration between the current moment of the boiling cycle and the start moment of the boiling cycle.

[0163] Step S17: When the running time of the boiling cycle reaches the total duration of the boiling cycle, the running time of the boiling cycle is reset to zero.

[0164] In this embodiment of the application, when the running time of the boiling cycle reaches the total duration of the boiling cycle, that is, the cooking appliance has completed one boiling cycle, the running time of the boiling cycle is reset to zero so that the next boiling cycle can continue to be boiled.

[0165] In one embodiment, there are multiple boiling periods within each boiling cycle, and in two adjacent boiling periods, the maximum boiling degree of the preceding boiling period is greater than the maximum boiling degree of the following boiling period.

[0166] The maximum boiling intensity in the previous boiling period is greater than that in the subsequent boiling period; that is, the maximum boiling intensity in the previous period is more intense than that in the subsequent boiling period.

[0167] For example, the preset temperature of the later boiling period is lower than the preset temperature of the earlier boiling period, that is, the preset temperature of the earlier boiling period is higher than the preset temperature of the later boiling period, so that the maximum boiling degree of the earlier period is more intense than the maximum boiling degree of the later boiling period.

[0168] For example, the preset temperature change rate of the later boiling period is less than the preset temperature change rate of the earlier boiling period, that is, the preset temperature change rate of the earlier boiling period is greater than the preset temperature change rate of the later boiling period, so that the maximum boiling degree of the earlier period is more intense than the maximum boiling degree of the later boiling period.

[0169] For example, the heating power for each boiling period is adjusted according to the state of the pressure relief valve, with the minimum heating power of the previous boiling period being greater than the maximum heating power of the next boiling period, so that the maximum boiling degree of the previous period is more intense than the maximum boiling degree of the next boiling period.

[0170] In this embodiment of the application, in two adjacent boiling periods, the maximum boiling degree of the previous boiling period is greater than that of the next boiling period. This makes the boiling degree of the cooking chamber decrease gradually within a boiling cycle, which is beneficial for cooking food at different maximum boiling degrees in different periods. It also allows the boiling cycle to end at the lowest possible maximum boiling degree in the last period, thus avoiding excessive boiling in the cooking chamber at the end of the boiling cycle.

[0171] In one embodiment, the pressure limiting value of the pressure limiting valve 2 is less than or equal to 5 kPa.

[0172] For example, the pressure limiting value of pressure relief valve 2 is greater than or equal to 1 kPa.

[0173] For example, the pressure limiting value of the pressure limiting valve 2 can be 1 kPa, 2 kPa, 3 kPa, 4 kPa or 5 kPa.

[0174] In this embodiment, the pressure limiting valve 2 has a small pressure limiting value. After boiling in the cooking chamber 11, the small boiling degree and amount of steam can open the pressure limiting valve 2, which makes it easier to control the continuous boiling of the cooking chamber 11.

[0175] In one embodiment, please refer to Figure 1 The diameter of the exhaust channel 12 corresponding to the pressure relief valve 2 is greater than or equal to 10 mm. The larger exhaust channel 12 corresponding to the pressure relief valve 2 is conducive to the rapid discharge of steam in the cooking chamber 11.

[0176] It should be noted that the exhaust passage 12 covers the opening through which the exhaust passage 12 connects to the outside.

[0177] For example, the diameter of the exhaust channel 12 corresponding to the pressure relief valve 2 can be 10mm, 12mm, 15mm, 20mm or 30mm.

[0178] In one embodiment, the cross-sectional area of ​​the exhaust channel 12 corresponding to the pressure relief valve 2 is greater than or equal to 80 mm². 2The pressure relief valve 2 has a larger exhaust channel 12, which facilitates the rapid discharge of steam from the cooking cavity 11.

[0179] For example, the cross-sectional area of ​​the exhaust passage 12 of the pressure relief valve 2 is greater than or equal to 80 mm². 2 The cross-sectional area of ​​the exhaust passage 12 is less than or equal to 300 mm². 2 .

[0180] For example, the cross-sectional area of ​​the exhaust passage 12 corresponding to the pressure relief valve 2 can be 80 mm². 2 90mm 2 100mm 2 150mm 2 200mm 2 230mm 2 260mm 2 280mm 2 Or 300mm 2 .

[0181] In one embodiment, please refer to Figure 4 The figure illustrates the operation of a complete boiling cycle. This cycle consists of two boiling periods: the earliest first boiling period and the latest second boiling period. Boiling is controlled by the temperature of the target fluid with pressure relief valve 2 open. The cooking method includes:

[0187] Step S104: Set the preset temperature T1 and / or preset temperature change rate K1 corresponding to the first boiling period, the preset temperature T2 and / or preset temperature change rate K2 corresponding to the second boiling period, the duration time1 of the first boiling period, and the total duration timeP of the boiling cycle.

[0200] If yes, proceed to step S108; otherwise, proceed to step S113.

[0201] Step S113: Heat with the second power, then proceed to step S115.

[0202] The second power is less than the first power.

[0203] Step S114: Clear timeC.

[0204] Step S115: Determine whether boiling control has ended;

[0205] If yes, proceed to step S116; otherwise, proceed to step S102.

[0206] Step S116: End.

[0207] In one embodiment, please refer to Figure 5 The diagram illustrates the operation of a complete boiling cycle.
