[0048] 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.

[0049] 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.

[0050] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the directions in normal use, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions in normal use.

[0051] 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.

[0052] In related technologies, cooking appliances have a covered stewing mode, a frying mode, and a preset mode. Each cooking mode can achieve a corresponding cooking effect. During the cooking process, after the food is placed in the cooking cavity and cooked for a period of time, the user needs to select a cooking mode. The cooking appliance then runs the user-selected cooking mode and cooks the food with the cooking parameters corresponding to the cooking mode. However, the cooking appliance cannot automatically select a cooking mode, indicating that the cooking appliance lacks sufficient intelligence.

[0053] In one embodiment, please refer to Figure 1 The cooking appliance includes a cooking body 8, a cavity cover 6, a heater 7, a first thermometer 1, a second thermometer 2, a pressure relief valve 5, and an exhaust port 4. The cooking cavity 3 is formed in the cooking body 8. The cavity cover 6 is detachably installed over the cooking cavity 3. The second heater 7 and the second thermometer 2 are both installed in the cooking body 8. The heater 7 is located on the bottom outer side of the cooking cavity 3. The second thermometer 2 is located on the bottom outer side of the cooking cavity 3 to measure the temperature at the bottom of the cooking cavity 3. The exhaust port 4 is connected to the cooking cavity 3 to discharge the gas inside the cooking cavity 3. The pressure relief valve 5 is used to restrict the exhaust from the exhaust port 4. The first thermometer 1 is installed at the exhaust port 4.

[0054] This application provides a cooking method in one embodiment; please refer to [link / reference]. Figure 2 Cooking methods include:

[0055] Step S1: Select the cooking mode of the cooking appliance based on the temperature measured by the first thermometer 1 and the temperature measured by the second thermometer 2. The cooking modes include stewing mode with lid closed, frying mode and preset mode. The first thermometer 1 can measure the temperature of the target fluid when the pressure relief valve 5 is open. The target fluid is the fluid discharged from the cooking chamber 3 of the cooking appliance through the pressure relief valve 5 and the exhaust port 4. The second thermometer 2 is located at the bottom of the cooking chamber 3 and on the outside of the cooking chamber 3.

[0056] Step S2: Cook the food in the cooking chamber 3 according to the selected cooking mode.

[0057] It should be noted that "closed" means that the lid 6 of the cooking chamber 3 is placed on the cooking chamber 3, sealing the cooking chamber 3. The fluid inside the cooking chamber 3 is mainly discharged through the pressure relief valve 5 and the exhaust port 4. "Open" means that the lid 6 of the cooking chamber 3 is open, and the cooking chamber 3 is directly connected to the outside. There is no pressure inside the cooking chamber 3, and the fluid inside the cooking chamber 3 is discharged directly from the opening of the cooking chamber 3. The fluid inside the cooking chamber 3 is basically not discharged through the pressure relief valve 5 and the exhaust port 4.

[0058] It should be noted that, with the lid closed, when the pressure inside the cooking chamber 3 exceeds the pressure limit of the pressure relief valve 5, the pressure relief valve 5 is open, and the fluid inside the cooking chamber 3 is discharged outside through the exhaust port 4, allowing the first thermometer 1 to measure the temperature of the target fluid. When the pressure inside the cooking chamber 3 is less than or equal to the pressure limit of the pressure relief valve 5, the pressure relief valve 5 is closed, no fluid is discharged from the exhaust port 4, the cooking chamber 3 is sealed, and the temperature measured by the first thermometer 1 is the ambient temperature outside the cooking chamber 3. With the lid open, the cooking chamber 3 is directly connected to the outside, and the fluid inside the cooking chamber 3 is discharged directly from the opening of the cooking chamber 3. The fluid spills into the vicinity of the first thermometer 1, causing the temperature measured by the first thermometer 1 to rise to a certain extent, but not significantly.

[0059] It should be noted that the preset mode primarily operates with the lid open. However, even with the lid closed, the cooking start time is shorter, and the temperature measured by the first thermometer 1 is lower. In this case, the preset mode will still run to cook the food in the cooking cavity 3. After repeatedly running multiple cycles of the preset mode, the temperature measured by the first thermometer 1 will be higher, and the cooking appliance will meet the conditions for the closed-lid stewing mode. In this case, the closed-lid stewing mode will be run to cook the food in the cooking cavity 3. The preset mode is mainly used for cooking food.

[0060] The food inside the cooking chamber 3 is cooked using the selected cooking mode, that is, the cooking parameters corresponding to the corresponding cooking mode are used to cook the food. For example, cooking parameters include heating power or heating time.

[0061] For example, the first temperature sensor 1 is disposed on the top outer side of the cooking cavity 3.

[0062] For example, the first temperature sensor 1 is located at the exhaust port 4.

[0063] For example, when the pressure inside the cooking chamber 3 is greater than the pressure limit value of the pressure limiting valve 5, the pressure limiting valve 5 is opened by the airflow inside the cooking chamber 3.

[0064] In this embodiment, the cooking environment of the food can be identified based on the temperature measured by the first thermometer 1 and the temperature measured by the second thermometer 2, thereby automatically selecting the corresponding cooking mode to cook the food in the cooking cavity 3. During the food cooking process, automatic switching between the covered stewing mode, the frying mode and the preset mode is realized. The automatic cooking mode does not require manual switching by the user, thereby improving the intelligence level of the product, enhancing the product's competitiveness and user experience.

[0065] For example, the cooking appliance only has a stewing mode with lid, a frying mode, and a preset mode.

[0066] For example, the cooking appliance also includes other cooking modes besides the covered stewing mode, frying mode and preset mode, such as the baking mode.

[0067] In one embodiment, selecting the cooking mode of the cooking appliance based on the temperature measured by the first thermometer 1 and the temperature measured by the second thermometer 2 includes:

[0068] When the temperature measured by the first thermometer 1 is greater than or equal to the first preset temperature, select the cooking mode of the cooking appliance as the covered stewing mode.

[0069] Cook the food in cooking cavity 3 using the covered stewing mode.

[0070] It should be noted that the first preset temperature is the temperature of the target fluid discharged through the exhaust port 4 via the pressure relief valve 5 when the pressure relief valve 5 is open, as measured by the first thermometer 1. The first preset temperature is greater than the ambient temperature.

[0071] It should be noted that the second preset temperature was determined experimentally.

[0072] With the lid closed, the cooking cavity 3 has a certain pressure, the steam temperature is high, and the temperature of the target fluid is also high. The temperature of the target fluid measured by the first thermometer 1 with the lid closed is significantly higher than the temperature measured by the first thermometer 1 with the cooking appliance open. When the temperature measured by the first thermometer 1 is greater than or equal to the first preset temperature, it can be considered that the cavity lid 6 of the cooking cavity 3 is in the closed state.

[0073] The food in the cooking chamber 3 is cooked using the covered stewing mode, that is, the cooking parameters corresponding to the covered stewing mode are used to cook the food, such as the heating power and heating time corresponding to the covered stewing mode.

[0074] In this embodiment, when the cooking cavity 3 is heated to a sufficiently high temperature, the pressure inside the cooking cavity 3 can reach the pressure limit value of the pressure limiting valve 5 when the lid is closed. The cooking appliance then discharges the target fluid through the exhaust port via the pressure limiting valve 5, and the first thermometer 1 can measure the temperature of the target fluid. When the temperature measured by the first thermometer 1 is greater than or equal to the first preset temperature, it can be determined that the first thermometer 1 is measuring the temperature of the target fluid. It is then determined that the lid 6 of the cooking cavity 3 is in the closed state, and the cooking appliance meets the conditions for operating the closed stewing mode. The closed stewing mode is selected to cook the food inside the cooking cavity 3. In the closed stewing mode, the cooking cavity 3 is closed by the lid 6, and the heat loss inside the cooking cavity 3 is slower. The cooking cavity 3 can maintain a higher temperature to cook the food, thus accelerating the cooking speed. The cooking appliance uses the relationship between the first thermometer 1 and the first preset temperature as a judgment condition to determine the opening and closing state of the lid 6 of the cooking cavity 3, and further automatically selects the closed stewing mode, improving the intelligence of the cooking appliance.

[0075] It is understood that the cooking mode of the cooking appliance is selected as the closed stewing mode, not limited to when the temperature measured by the first thermometer 1 is greater than or equal to the first preset temperature. For example, the cooking appliance includes a third thermometer disposed in the cooking cavity 3, which measures the temperature at the top of the cooking cavity 3. When the temperature measured by the third thermometer is greater than or equal to the first preset temperature, the cooking mode of the cooking appliance is selected as the closed stewing mode.

[0076] In one embodiment, the first preset temperature is greater than or equal to 40°C, and the first preset temperature is less than or equal to 100°C.

[0077] For example, the first preset temperature is 40°C, 50°C, 80°C, or 100°C.

[0078] In this embodiment of the application, the first preset temperature is greater than or equal to 40°C, the first preset temperature is less than or equal to 100°C, and the first preset temperature is within a suitable range. When the first temperature sensor 1 is greater than or equal to the first preset temperature, the first temperature sensor 1 measures the temperature of the target fluid.

[0079] It is understood that the first preset temperature is not limited to being greater than or equal to 40°C, nor is it limited to being less than or equal to 100°C.

[0080] For example, the first preset temperature is less than 40°C.

[0081] For example, the first preset temperature is greater than 100°C.

[0082] In one embodiment, selecting the cooking mode of the cooking appliance based on the temperature measured by the first thermometer 1 and the temperature measured by the second thermometer 2 includes:

[0083] The temperature change rate of the first thermometer 1 is obtained based on the temperature measured by the first thermometer 1 within a first preset time period.

[0084] When the temperature change rate of the first thermometer 1 is greater than or equal to the first preset change rate, the cooking mode of the cooking appliance is selected as the covered stewing mode.

[0085] Cook the food in cooking cavity 3 using the covered stewing mode.

[0086] It should be noted that the temperature change rate of the first thermometer 1 refers to the calculated rate of temperature change obtained from the temperature measured by the first thermometer 1 within the first preset time period. The temperature change rate reflects the speed of temperature change within the first preset time period. When the temperature measured by the first thermometer 1 rises within the first preset time period, the temperature change rate is greater than 0; when the temperature measured by the first thermometer 1 falls within the first preset time period, the temperature change rate is less than 0; when the temperature measured by the first thermometer 1 remains constant within the first preset time period, the temperature change rate is 0. A larger temperature change rate indicates a faster temperature rise, and a smaller temperature change rate indicates a faster temperature fall.

[0087] It should be noted that when the lid is closed, when the fluid in the cooking cavity 3 is discharged through the pressure relief valve 5 and the exhaust port 4, the temperature measured by the first thermometer 1 is the temperature of the target fluid, and the temperature change rate of the first thermometer 1 is the temperature change rate of the target fluid.

[0088] In this embodiment of the application, when the lid is closed, the temperature measured by the first thermometer 1 within a first preset time period is used to obtain the temperature change rate of the first thermometer 1. The relationship between the temperature change rate of the first thermometer 1 and the first preset change rate is used as the judgment condition for the closed stewing mode. This reduces the influence of ambient temperature on the temperature measured by the first thermometer 1, and the cooking appliance can more accurately judge the temperature of the target fluid, automatically select the cooking mode, and improve the intelligence of the cooking appliance.

[0089] In one embodiment, selecting the cooking mode of the cooking appliance based on the temperature measured by the first thermometer 1 and the temperature measured by the second thermometer 2 includes:

[0090] When the lid 6 of the cooking cavity 3 is in the open state, and the temperature measured by the second temperature sensor 2 is greater than or equal to the second preset temperature, the cooking mode is selected as the frying mode.

[0091] Cook the food in cooking cavity 3 using the frying / stir-frying mode;

[0092] When the lid 6 of the cooking cavity 3 is in the open state, if the temperature measured by the second temperature sensor 2 is lower than the second preset temperature, the cooking mode is selected as the preset mode.

[0093] Cook the food in cooking chamber 3 using the preset mode.

[0094] It should be noted that the second preset temperature was determined experimentally.

[0095] The preset mode runs when the lid is open, and is mainly used for cooking food when the lid is open.

[0096] The food in the cooking chamber 3 is cooked using a preset mode, that is, the food is cooked using the cooking parameters corresponding to the preset mode, such as heating power or heating time.

[0097] The food in the cooking chamber 3 is cooked using the frying / stir-frying mode, that is, the food is cooked using the cooking parameters corresponding to the frying / stir-frying mode, such as heating power or heating time.

[0098] With the lid open, the temperature measured by the second temperature sensor 2 located on the outer side of the bottom of the cooking cavity 3 allows selection of a suitable cooking mode between the preset mode and the frying / stir-frying mode. The frying / stir-frying mode requires high heat, and the temperature measured by the second temperature sensor 2 in this mode is significantly higher than the temperatures in other cooking modes. The temperature measured by the second temperature sensor 2 distinguishes between the frying / stir-frying mode and the preset mode.

[0099] When the lid is open, if there is a large amount of water in the food being cooked in the cooking chamber 3, the boiling temperature of the water in the cooking chamber 3 will remain at the boiling point, and the temperature measured by the second thermometer 2 will not be too high.

[0100] When the lid is open, the heater 7 has just started heating. The temperature measured by the second thermometer 2 is low. The cooking appliance executes the preset mode. During the process of repeatedly executing the preset mode to cook food, when the amount of water in the cooking cavity 3 is small or even empty, the temperature measured by the second thermometer 2 continues to rise. When the temperature measured by the second thermometer 2 is greater than or equal to the second preset temperature, the cooking appliance selects the frying mode to continue cooking food.

[0101] In this embodiment, when there is a large amount of water in the cooking cavity 3, the heater 7 heats the cooking cavity 3. The water in the cooking cavity 3 evaporates and absorbs heat, resulting in a slower temperature rise at the bottom of the cooking cavity 3 and a relatively low temperature inside the cooking cavity 3. The temperature measured by the second thermometer 2 is also relatively low. In the open state, the cooking modes include a preset mode and a frying / stir-frying mode. When the temperature measured by the second thermometer 2 is lower than the second preset temperature, it is determined that there is a large amount of water in the cooking cavity 3, and the cooking appliance automatically selects the preset mode to cook the food in the cooking cavity 3. During the cooking process, the temperature inside the cooking cavity 3 continuously rises. When the temperature measured by the second thermometer 2 is greater than or equal to the second preset temperature, it is determined that there is little or no water in the cooking cavity 3, and the cooking appliance automatically selects the frying / stir-frying mode to cook the food in the cooking cavity 3. In the open state, the cooking appliance automatically selects either the preset mode or the frying / stir-frying mode based on the relationship between the second thermometer 2 and the second preset temperature, thus improving the intelligence of the cooking appliance.

[0102] In one embodiment, the second preset temperature is greater than or equal to 110°C, and the second preset temperature is less than or equal to 160°C.

[0103] For example, the second preset temperature can be 110°C, 125°C, 140°C, 150°C or 160°C.

[0104] In this embodiment, the second preset temperature is greater than or equal to 110°C and less than or equal to 160°C. Based on the relationship between the temperature measured by the second thermometer 2 and the second preset temperature, the moisture state in the cooking cavity 3 can be determined, thereby automatically selecting the preset mode or the frying mode.

[0105] It is understood that the second preset temperature is not limited to being greater than or equal to 110°C, nor is it limited to being less than or equal to 160°C. As long as the second preset temperature is within a suitable range, the moisture state inside the cooking cavity 3 can be determined by using the relationship between the second thermometer 2 and the second preset temperature as the judgment condition.

[0106] For example, the second preset temperature is less than 110°C, such as 100°C.

[0107] For example, the second preset temperature is greater than 160°C, such as 170°C.

[0108] In one embodiment, the cooking method further includes:

[0109] Step S3: When the temperature measured by the first thermometer 1 is lower than the first preset temperature, the opening and closing state of the cavity cover 6 of the cooking cavity 3 is determined to be the open state.

[0110] For example, determining the opening / closing state of the cavity lid 6 based on the relationship between the temperature measured by the first thermometer 1 and the first preset temperature is a prediction of the opening / closing state of the cavity lid 6. In the open state, the temperature measured by the first thermometer 1 is lower. In the closed-lid stewing mode, at the beginning of heating, the pressure inside the cooking cavity 3 has not reached the pressure limit value of the pressure relief valve 5, and the pressure relief valve 5 has not yet opened. The temperature measured by the first thermometer 1 is approximately the ambient temperature, and the temperature measured by the first thermometer 1 is also relatively low, so the cavity lid 6 can be considered to be in the open state. In this case, the judgment of the cavity lid 6's state is a prediction. If the amount of food and water in the cooking cavity 3 is sufficient to cook the food, and the cavity lid 6 is actually in the closed state, as the preset mode is repeatedly executed, the pressure inside the cooking cavity 3 increases, opening the pressure relief valve 5, making the temperature measured by the first thermometer 1 greater than or equal to the first preset temperature. The cooking appliance will then correct the predicted open state to the closed state and execute the closed-lid stewing mode. If the food in the cooking cavity 3 has enough water to cook the food, and the cavity lid 6 is actually in an open state, the cooking appliance will continue to execute the aforementioned preset mode to cook the food with the lid open.

[0111] It should be noted that when the lid 6 of the cooking cavity 3 is closed, and the heating time of the cooking cavity 3 is short, the temperature inside the cooking cavity 3 is low, and the temperature measured by the first thermometer 1 is low. The temperature measured by the first thermometer 1 may be lower than the first preset temperature. The cooking appliance judges this situation to be an open state, and the cooking appliance selects the preset mode for cooking. The preset mode is similar to the closed stewing mode in the early stage and does not affect the closed stewing mode.

[0112] It should be noted that when the lid is open, the cooking chamber 3 is directly connected to the outside. The fluid in the cooking chamber 3 is directly released from the cooking chamber 3. The fluid in the cooking chamber 3 will not be discharged through the pressure relief valve 5 and the exhaust port 4. The temperature measured by the first thermometer 1 is the ambient temperature or the temperature of the fluid that has spilled into the vicinity of the first thermometer 1. The temperature measured by the first thermometer 1 is relatively low.

[0113] In this embodiment, the opening and closing state of the cavity cover 6 is initially predicted by the temperature measured by the first thermometer 1. During the subsequent heating process, the opening and closing state of the cavity cover 6 is judged again based on the temperature measured by the first thermometer 1, and finally a cooking mode corresponding to the amount of food and water is obtained more accurately. The temperature measured by the first thermometer 1 can simplify the judgment of the opening and closing state of the cavity cover 6, making the conditions for selecting the cooking mode of the cooking appliance simpler.

[0114] In one embodiment, the cooking method further includes:

[0115] Step S4: Obtain the temperature change rate of the first thermometer 1 based on the temperature measured by the first thermometer 1 within a first preset time period;

[0116] When the temperature change rate of the first thermometer 1 is less than the first preset change rate, the opening and closing state of the cavity cover 6 of the cooking cavity 3 is determined to be the open state.

[0117] It should be noted that when the lid 6 of the cooking cavity 3 is closed, and the heating time of the cooking cavity 3 is short, the temperature inside the cooking cavity 3 is low, and the temperature change rate of the first thermometer 1 is low. The temperature change rate of the first thermometer 1 may be lower than the first preset temperature change rate. The cooking appliance judges this situation to be an open state, and the cooking appliance selects the preset mode for cooking. The preset mode is similar to the closed stewing mode in the early stage and does not affect the closed stewing mode.

[0118] It is understandable that when the temperature change rate of the first thermometer 1 is greater than or equal to the first preset change rate, the opening and closing state of the cavity cover 6 of the cooking cavity 3 is determined to be the closed state.

[0119] In this embodiment, when the cooking chamber 3 is in the open state, the cover 6 is removed from the cooking chamber 3, allowing the cooking chamber 3 to directly communicate with the outside. The fluid inside the cooking chamber 3 directly escapes from the cooking chamber 3 and does not exit through the pressure relief valve 5 via the exhaust port 4. The temperature measured by the first thermometer 1 is either the ambient temperature or the temperature of the fluid that has spilled into the vicinity of the first thermometer 1. The temperature measured by the first thermometer 1 is relatively low, and the temperature change rate of the first thermometer 1 is small. When the temperature change rate of the first thermometer 1 is less than a first preset change rate, it is determined that the first thermometer 1 is measuring the ambient temperature, and the cover 6 of the cooking chamber 3 is in the open state.

[0120] In one embodiment, the first preset temperature is greater than or equal to 40°C, and the first preset temperature is less than or equal to 100°C.

[0121] For example, the first preset temperature is 40°C, 50°C, 80°C, or 100°C.

[0122] In this embodiment of the application, the first preset temperature is greater than or equal to 40°C, the first preset temperature is less than or equal to 100°C, and the first preset temperature is within a suitable range. When the first temperature sensor 1 is less than the first preset temperature, it can be determined that the cavity cover 6 of the cooking cavity 3 is in an open state. When the first temperature sensor 1 is greater than or equal to the first preset temperature, it can be determined that the cavity cover 6 of the cooking cavity 3 is in a closed state.

[0123] It is understood that the first preset temperature is not limited to being greater than or equal to 40°C, nor is it limited to being less than or equal to 100°C.

[0124] For example, the first preset temperature is less than 40°C.

[0125] For example, the first preset temperature is greater than 100°C.

[0126] In one embodiment, selecting the cooking mode of the cooking appliance based on the temperature measured by the first thermometer 1 and the temperature measured by the second thermometer 2 includes:

[0127] The temperature change rate of the second thermometer 2 is obtained based on the temperature measured by the second thermometer 2 within a second preset time period.

[0128] When the lid 6 of the cooking chamber 3 is in the open state, and the temperature change rate of the second temperature sensor 2 is greater than or equal to the second preset change rate, the cooking mode is selected as the frying mode.

[0129] Cook the food in cooking cavity 3 using the frying / stir-frying mode;

[0130] When the lid 6 of the cooking cavity 3 is in the open state, and the temperature change rate of the second temperature sensor 2 is less than the second preset change rate, the cooking mode is selected as the preset mode.

[0131] Cook the food in cooking chamber 3 using the preset mode.

[0132] It should be noted that the temperature change rate of the second thermometer 2 refers to the temperature change rate obtained by calculation from the temperature measured by the second thermometer 2 within the second preset time period.

[0133] In this embodiment, when there is a large amount of water in the cooking cavity 3, the cooking appliance heats the cooking cavity 3. The water in the cooking cavity 3 evaporates and absorbs heat, resulting in a slower temperature rise at the bottom of the cooking cavity 3 and a smaller temperature change rate of the second thermometer 2. When the lid is open, if the temperature change rate of the second thermometer 2 is less than a second preset temperature change rate, the temperature rise at the bottom of the cooking cavity 3 is slow, indicating a large amount of water in the cooking cavity 3. The cooking appliance automatically selects a preset mode to cook the food in the cooking cavity 3. During cooking, the water in the cooking cavity 3 continuously evaporates, the temperature rises faster, and the temperature change rate of the second thermometer 2 continuously increases. When the temperature change rate of the second thermometer 2 is greater than or equal to the second preset temperature change rate, the temperature rises rapidly at the bottom of the cooking cavity 3, indicating a small amount of water or no water in the cooking cavity 3. The cooking appliance automatically selects a frying / stir-frying mode to cook the food in the cooking cavity 3. In the open state, the cooking appliance uses the relationship between the temperature change rate of the second thermometer 2 and the second preset change rate as a judgment condition to automatically select a preset mode or a frying / stir-frying mode, improving the intelligence of the cooking appliance.

[0134] In one embodiment, the pressure limiting value of the pressure limiting valve 5 is less than or equal to 5 kPa.

[0135] In this embodiment, when the lid is closed, the pressure inside the cooking chamber 3 is less than or equal to 5 kPa, the pressure limiting valve 5 is closed, and the exhaust port 4 is sealed, creating a sealed environment inside the cooking chamber 3. When the pressure inside the cooking chamber 3 exceeds 5 kPa, the pressure limiting valve 5 opens, the exhaust port 4 opens, and the fluid inside the cooking chamber 3 is discharged through the pressure limiting valve 5 and the exhaust port 4. The pressure limiting value of the pressure limiting valve 5 is less than or equal to 5 kPa, which can maintain the pressure inside the cooking chamber 3 below 5 kPa, creating a micro-pressure cooking environment inside the cooking chamber 3.

[0136] It is understood that the pressure limiting value of pressure relief valve 5 is less than or equal to 5 kPa. For example, the pressure limiting value of pressure relief valve 5 is greater than 5 kPa, such as 8 kPa.

[0137] Preferably, the pressure limiting value of the pressure limiting valve 5 is less than or equal to 5 kPa, and the pressure limiting value of the pressure limiting valve 5 is greater than or equal to 1 kPa.

[0138] In one embodiment, the exhaust port 4 is opened or closed by the pressure relief valve 5, and the diameter of the exhaust channel of the exhaust port 4 is greater than or equal to 10 mm.

[0139] In one embodiment, the cross-sectional area of ​​the exhaust passage of the exhaust port 4 is greater than or equal to 80 square millimeters.

[0140] Preferably, the cross-sectional area of ​​the exhaust channel of the exhaust port 4 is greater than or equal to 80 square millimeters, and the cross-sectional area of ​​the exhaust channel of the exhaust port 4 is less than or equal to 300 square millimeters.
