[0074] As a commonly used cooking appliance, the electric pressure cooker is increasingly widely used in various cooking scenarios due to its advantages such as rapid cooking and good cooking effects. In the related art, when using an electric pressure cooker for cooking, the ingredients and water are first added to the inner pot together, and then the cooking cavity is heated to cook the ingredients, that is, water is added first and then heated. Since the electric pressure cooker must be able to generate pressure and sufficient steam is required, a sufficient amount of water needs to be added. However, a large amount of water will cause the pressure in the cooking cavity to rise slowly, resulting in a longer cooking time.

[0075] To solve the problems existing in the related art, the embodiments of the present application provide a cooking method, a cooking module, a cooking appliance, and a computer storage medium. When cooking, the cooking cavity is heated first and then water is added to the cooking cavity. Since the cooking cavity already has a certain temperature when water is added to the cooking cavity, the water in the cooking cavity can be heated up faster and evaporated faster, and thus the pressure in the cooking cavity can rise faster, so as to reduce the cooking time.

[0076] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0077] The embodiments of the present application provide a cooking appliance 10, and the cooking appliance 10 provided by the embodiments of the present application can inject water into the cooking cavity 300 when the cooking cavity 300 is in a high-pressure state.

[0078] As Figure 1 shown, the cooking appliance 10 includes a pot body 200 and a lid body 100, and the pot body 200 and the lid body 100 form a cooking cavity 300. The cooking cavity 300 is used to store food. A heating device and the like are also provided in the pot body 200 for heating the food in the cooking cavity 300 to cook the food in the cooking cavity 300.

[0079] Among them, the pot body 200 includes a main body and a container. Structures such as a heating device are installed on the main body, and the food is placed in the container. The lid body 200 and the container form the cooking cavity 300. The pot body 200 can be a base, and the bottom of the container is placed on the base. The pot body 200 can also have a receiving cavity, and the bottom of the container can be placed in the installation groove, or the entire container can be accommodated in the receiving cavity.

[0080] The cooking appliance 10 further includes a water injection module 400, as Figure 2 shown. The water injection module 400 includes a mounting base 410 and a valve core member 420. The mounting base 410 is mounted on the pot body 200 or the lid body 100. The mounting base 410 has a flow channel 412, a water inlet 413 and a water outlet 414 that communicate with the flow channel 412. The water outlet 414 is located within the cooking cavity 300.

[0081] It should be understood that the water inlet 413 of the water injection module 400 is used to communicate with a water source, so that the water source can enter the flow channel 412 through the water inlet 413 and then flow to the water outlet 414. The water outlet 414 is located within the cooking cavity 300, so that the water flowing out of the water outlet 414 can enter the cooking cavity 300 to achieve the function of injecting water into the cooking cavity 300. Since the lid body 100 and the pot body 200 are connected to form the cooking cavity 300, the mounting base 410 can be mounted on the pot body 200 or on the lid body 100. There is no limitation in this application, as long as the water outlet 414 can be located within the cooking cavity 300 after installation.

[0082] The pot body 200 and the lid body 100 can be connected to form the cooking cavity 300. For example, after the lid body 100 is aligned with the pot body 200, it is rotated by a certain angle and snapped onto the pot body. Another example is that one side of the lid body 100 is rotatably connected to one side of the pot body 200, and the other side of the lid body 100 is snap-connected to the other side of the pot body 200. The pot body 200 and the lid body 100 can also not be connected to form the cooking cavity 300. For example, the lid body 100 is directly placed on the pot body 200 to form the cooking cavity 300 with the pot body 200.

[0083] The mounting base 410 is the installation foundation of the valve core member 420, and can provide support and limit for the valve core member 420. The valve core member 420 of the water injection module 400 is installed in the flow channel 412, and the valve core member 420 can disconnect the water inlet 413 and the water outlet 414.

[0084] In some embodiments, the valve core member 420 can disconnect the water inlet 413 and the water outlet 414 under the action of the air pressure in the cooking cavity 300.

[0085] The water inlet 413 and the water outlet 414 are disconnected, which means that the water inlet 413 and the water outlet 414 are not connected. Under the action of the air pressure in the cooking cavity 300, the valve core 420 can block any one of the water inlet 413, the flow channel 412 or the water outlet 414, so that the water inlet 413 and the water outlet 414 are not connected, so that the gas in the cooking cavity 300 will not be discharged from the water inlet 413, so that the cooking appliance 10 can achieve the functions of pressurization and pressure maintenance; at the same time, when the cooking appliance 10 is cooking food, the food in the cooking cavity 300 will not or will be difficult to enter the water injection module 400, thereby avoiding blockage of the water injection module 400 and ensuring that the water injection function of the water injection module 400 can be achieved. When water is added, under the action of water pressure, the water flow pushes the valve core 420 to move in the direction from the water inlet 413 to the water outlet 414. The water inlet 413 and the water outlet 414 are connected, so that the water flow entering the water inlet 413 can be discharged through the water outlet 414 and enter the cooking cavity 300.

[0086] The cooking utensil 10 of the present application can inject water into the cooking cavity 300 when the cooking cavity 300 is under pressure. When injecting water, there is no need to vent or reduce the pressure in the cooking cavity 300, nor is there any need to open the cover 100. When injecting water, the water can be injected through the water inlet 413, which simplifies the process of replenishing water in the cooking utensil 10 during cooking, helps to ensure the taste of food, saves cooking time, and is convenient for users.

[0087] There are various ways for the valve core member 420 to disconnect the water inlet 413 and the water outlet 414, which are not limited in this application.

[0088] In some embodiments, the valve core 420 disconnects the water inlet 413 and the water outlet 414 by blocking the water inlet 413. The valve core 420 may be a spherical member located in the flow channel 412, with a gap between the flow channel 412 and the valve core 420. Under the action of the air pressure in the cooking chamber 300, the valve core 420 moves toward the water inlet 413 and blocks the water inlet 413, preventing gas or food from being discharged through the water inlet 413. When the air pressure in the cooking chamber 300 is low or water is being injected into the cooking chamber 300, the valve core 420 moves downward under the action of gravity or water pressure, unblocking the water inlet 413 and allowing the water inlet 413 to communicate with the water outlet 414, thereby enabling the water injection function of the cooking chamber 300.

[0089] In some embodiments, the valve core 420 can also disconnect the water inlet 413 and the water outlet 414 by blocking the water outlet 414. The lower end of the valve core 420 can extend outside the water outlet 414. Under the action of the air pressure in the cooking chamber 300, the lower end of the valve core 420 will move toward the water outlet 414 until the lower end of the valve core 420 blocks the water outlet 414, preventing gas or food from being discharged through the water inlet 413. When the air pressure in the cooking chamber 300 is low or water is injected into the cooking chamber 300, the valve core 420 moves downward under the action of gravity or water pressure, unblocking the water outlet 414, allowing the water inlet 413 and the water outlet 414 to communicate, thereby realizing the water injection function of the cooking chamber 300.

[0090] In some embodiments, the valve core member 420 may include a first sealing member 422 mounted within the flow channel 412, a valve core body 423, and a return member 424. The first sealing member 422 is mounted on the valve core body 423, and the return member 424 is connected to the valve core body 423 and the mounting seat 410. The return member 424 can be compressed when the water injection module 400 is filled with water. The return member 424 can provide a restoring force to the first sealing member 422 to seal the first flow channel 4121, thereby disconnecting the water inlet 413 and the water outlet 414.

[0091] With this design, when the water injection module 400 is not injected with water, under the action of the reset member 424, the valve core body 423 drives the first sealing member 422 to press against the mounting seat 410, so that the first flow channel 4121 is sealed, thereby disconnecting the water inlet 413 and the water outlet 414.

[0092] In this way, when the cooking utensil 10 is cooking food, due to the sealing effect of the first sealing member 422, the food in the cooking cavity 300 will not or will hardly enter the water injection module 400, thereby avoiding blockage and contamination of the water injection module 400 to a certain extent, ensuring that the water injection function of the water injection module 400 can be realized, and also ensuring the cleanliness and hygiene of the water injection module 400; in this way, when the cooking utensil is a high-pressure cooking utensil, due to the sealing effect of the first sealing member 422, the gas in the cooking cavity 300 will not be discharged from the water inlet 413, so that the cooking utensil 10 can achieve the functions of pressurization and pressure maintenance.

[0093] When the water injection module 400 is injecting water, under the action of water pressure, the water flow pushes the first sealing member 422 and the valve core body 42 to move and compress the reset member 424, so that there is a gap between the first sealing member 422 and the flow channel 412, so that the water inlet 413 and the water outlet 414 are connected in the direction from the water inlet 413 to the water outlet 414, so that the water flow entering the water inlet 413 is discharged through the water outlet 414, thereby entering the cooking cavity 300 and realizing the water injection function.

[0094] In some embodiments, the valve core member 420 disconnects the water inlet 413 and the water outlet 414 by blocking the flow channel 412. As Figure 2 shown, the mounting seat 410 includes a valve seat 416 and a joint 417 connected to the valve seat 416. The water inlet 413 is provided on the joint 417, the water outlet 414 is provided on the valve seat 416, the flow channel 412 includes a first flow channel 4121 provided in the joint 417 and a second flow channel 4122 provided in the valve seat 416, and the valve core member 420 can block the first flow channel 4121 to disconnect the water inlet 413 and the water outlet 414. After such a design, the mounting seat 410 is composed of two parts, the valve seat 416 and the joint 417, and is designed in a split structure, which helps to simplify the processing technology and processing difficulty of the mounting seat 410. It should be understood that the first flow channel 4121 and the second flow channel 4122 are connected so that the water flowing into the first flow channel 4121 from the water inlet 413 then enters the second flow channel 4122 and finally flows out from the water outlet 414.

[0095] The connection method between the first seal 422 and the valve core body 423 is diverse and can be bonding, snap connection, etc., which is not limited here.

[0096] In some embodiments, the valve core member 420 has a pushing surface 426. Under the condition that the water injection module 400 injects water, the pushing surface 426 can move towards the direction of the water outlet 414 to push the impurities in the flow channel 412 out of the water outlet 414 to the outside of the water outlet channel 131.

[0097] During the use of the cooking appliance 10, it is inevitable that the food in the cooking cavity 300 enters the flow channel 412, resulting in the blockage of the flow channel 412 and affecting the water injection efficiency. After the pushing surface 426 is provided, under the water injection condition, the valve core member 420 will move towards the direction of the water outlet 414 under the action of water pressure, and the pushing surface 426 thereon will also move towards the direction of the water outlet 414, so as to push the food in the flow channel 412 out of the water outlet 414, relieving the blockage of the flow channel 412 by food to a certain extent and ensuring the water injection efficiency of the water injection module 400.

[0098] In some embodiments, the pushing surface 426 includes a first pushing surface 4261 and / or a second pushing surface 4262. The first pushing surface 4261 is annularly provided on the outer peripheral wall of the valve core member 420, and the second pushing surface 4262 is the end surface of the valve core member 420 facing the water outlet 414. That is to say, the pushing surface 426 can have only the first pushing surface 4261, or only the second pushing surface 4262, or both the first pushing surface 4261 and the second pushing surface 4262.

[0099] Based on the same inventive concept, an embodiment of the present application further provides a cooking appliance. At the hardware level, the cooking appliance includes a processor, and optionally also includes an internal bus, a network interface, and a memory.

[0104] Of course, in addition to the software implementation manner, the cooking appliance of this application does not exclude other implementation manners, such as a logic device or a combination of software and hardware, etc. That is to say, the execution subject of the following processing flow is not limited to each logic unit, and may also be hardware or a logic device.

[0105] Based on the same inventive concept, an embodiment of this application provides a cooking method, which is applied to the cooking appliance described above. The cooking appliance includes a pot body, a lid body that forms a cooking cavity with the pot body, a water injection module installed on the pot body or the lid body, and a heating device, and the water injection module is communicated with the cooking cavity.

[0106] Combined with Figure 3 , the specific steps of the cooking method include:

[0107] Step S100, in response to a cooking instruction, control the heating device to start heating the cooking cavity 300.

[0108] The cooking instructions include cooking modes, etc. For example, if the cooking instruction is to cook porridge, the cooking mode can be selected as quick porridge or delicate porridge. When the cooking appliance 10 receives the cooking instruction issued by the user, it responds to the cooking instruction and controls the heating device to start heating the cooking cavity 300. At this time, there is no water in the cooking cavity 300, that is, the heating device dry burns the cooking cavity 300 to quickly raise the temperature of the cooking cavity 300. Of course, from a safety perspective, the dry burning time should not be too long, and it can be controlled within about one minute.

[0109] The heating method of the cooking cavity 300 can be continuous heating or intermittent heating, as long as the cooking cavity 300 can be quickly heated up. It should be noted that if the intermittent heating method is adopted, in the subsequent steps, at least after each time water is added to the cooking cavity 300, it is necessary to maintain a heating state for a period of time to heat the water in the cooking cavity 300 and make the cooking cavity 300 pressurize.

[0110] Moreover, in order to make the heating-up speed of the cooking cavity 300 faster, before controlling the water injection module 400 to add the target volume of water into the cooking cavity 300, the heating device can be controlled to operate at full power.

[0111] Step S200, obtain the real-time temperature value inside the cooking cavity 300.

[0112] Among them, the real-time temperature value represents the temperature value at the current moment inside the cooking cavity 300. The real-time temperature value can be detected by a temperature sensor or by a temperature detection module. The interval time for obtaining the temperature value can be set, and the real-time temperature value is obtained once every first preset time.

[0113] After the heating device is started, the temperature value inside the cooking cavity 300 will continuously rise with the heating of the heating device. Since there is no water in the cooking cavity 300 after responding to the cooking instruction, if the temperature inside the cooking cavity 300 continues to rise, the situation of dry burning of the cooking cavity 300 will occur. And there is uncooked food to be cooked placed inside the cooking cavity 300. If the cooking cavity 300 is continuously heated without water, if the temperature is too high, it will also cause the uncooked food to change color and deteriorate, affecting the cooking effect. Therefore, during the heating process, the real-time temperature value is continuously obtained, and the real-time temperature value is used to judge whether the temperature inside the cooking cavity 300 is too high.

[0114] Step S300, if the condition that the real-time temperature value is greater than or equal to the first preset temperature value is met, then control the water injection module 400 to add the target volume of water into the cooking cavity 300.

[0115] In the related art, water is first injected into the cooking cavity and then the cooking cavity is heated. That is, the water starts to heat up from a lower temperature, so the evaporation process of the water is relatively long and the pressure rise in the cooking cavity is slow. In the embodiments of the present application, the cooking cavity 300 is first heated and then water is injected into the cooking cavity 300. That is, when the water is added to the cooking cavity 300, the cooking cavity 300 already has a relatively high temperature, which can make the water heat up faster and evaporate faster, and then make the pressure rise faster in the cooking cavity 300, reducing the cooking time. The first preset temperature value is the timing condition for adding water set in the embodiments of the present application. That is, when the real-time temperature value of the cooking cavity 300 is greater than or equal to the first preset temperature value, it means that the real-time temperature value of the cooking cavity 300 has reached a relatively high range at this time, which can make the water heat up faster. Therefore, in this step, it is necessary to judge whether the real-time temperature value is greater than or equal to the first preset temperature value to obtain the timing for adding water.

[0116] The first preset temperature value can be set at the factory or set by the user according to the actual cooking mode. Specifically, the first preset temperature value can be 170°-190°. In the case of dry burning, when heating at full power for about one minute, the temperature of the cooking cavity 300 can reach the above range.

[0117] The target capacity is the total amount of water required during the cooking process. Therefore, during the water addition process, it is necessary to control the water injection module 400 to add the target capacity of water into the cooking cavity 300 to ensure the cooking effect.

[0118] During the water addition process, the target capacity of water can be added at one time, or the water can be added in small amounts multiple times. When adding water in multiple times, since the amount of water added each time is small, the evaporation of the water can be faster, so the pressure rise in the cooking cavity 300 is faster, shortening the cooking time. Moreover, the small amount of water added each time can also avoid generating too much juice during the cooking process and ensure the taste of the ingredients. The situation of adding water in multiple times will be introduced in detail below.

[0119] In some embodiments, in combination with Figure 4 , step S300 may include step S310, step S320, step S330, and step S340.

[0120] Step S310, control the water injection module 400 to add a preset capacity of water into the cooking cavity 300; and accumulate the number of water addition times to obtain a count value; wherein, the preset capacity is related to the count value.

[0121] The number of water additions can be one or more, and the count value is accumulated. For example, for the first water addition, the count value is 1; for the second water addition, the count value is 2; for the third water addition, the count value is 3, and so on. The preset capacity is the amount of water added each time, and there is a corresponding preset capacity for each water addition. For example, the preset capacity for the first water addition is m, and the preset capacity for the second water addition is n, where m and n may be the same or different.

[0122] The number of water additions is related to the preset capacity and the target capacity. When both the target capacity and the preset capacity are determined, the number of water additions can be obtained. For example, when the preset capacity for each water addition is the same, the target capacity divided by the preset capacity directly gives the number of water additions. Of course, the preset capacity for each water addition can also be different, and the number of water additions can be obtained by allocating the preset capacity according to the target capacity. The following will introduce the ways to obtain the preset capacity and the target capacity.

[0123] In some embodiments, in combination with Figure 5 , step S310 may include step S311, step S312, and step S313.

[0124] Step S311, obtain the cooking mode information carried in the cooking instruction.

[0125] The cooking modes may include cooking rice, making soup, steaming, roasting meat, etc. The user can select the corresponding cooking mode according to their needs and issue a cooking instruction. In different cooking modes, the target capacity and the preset capacity of water are also different. For example, when making soup or porridge, the target capacity of water is larger, while when cooking rice, the target capacity of water is smaller. The setting of the preset capacity needs to meet the requirement of rapid pressure increase in the current cooking mode. That is, while achieving rapid pressure increase through adding water in small amounts multiple times, it also needs to meet the water demand in the current cooking mode. For example, when making soup or porridge, the water should not evaporate too much at one time, so the preset capacity for each water addition will be larger, and of course, the overall number of water additions will be smaller; while when cooking rice, the preset capacity for each water addition can be smaller, and thus the overall number of water additions will be larger.

[0126] Step S312, obtain the total amount of food in the cooking chamber 300.

[0127] A weighing sensor can be set in the pot body 200 to detect the total amount of food in the cooking chamber 300. When the food is placed in the cooking chamber 300, the weighing sensor can obtain the total amount of food in the cooking chamber 300. Obviously, in the same cooking mode, the larger the total amount of food, the more water is needed, and thus the target capacity and the preset capacity are larger.

[0128] Step S313, determine the preset capacity and the target capacity according to the total amount of food and the cooking mode information.

[0129] Under the same cooking mode, the greater the total amount of food, the greater the target capacity and the preset capacity. Similarly, when the total amount of food is the same, the target capacity and the preset capacity are different under different cooking modes. Therefore, the target capacity and the preset capacity of water need to be jointly determined by the total amount of food and the cooking mode.

[0130] Combined with Figure 6 , during the process of adding water to the cooking cavity 300 multiple times, the heating device is continuously heating differently. As the number of water additions increases, the air pressure value in the cooking cavity 300 will gradually increase, that is, the air pressure value in the cooking cavity 300 may be different after each water addition. Since the air pressure values are different, in order to enable the cooking cavity 300 to quickly boost pressure, it is necessary to adjust the heating power of the heating device, so as to ensure that it can be quickly heated after each water addition and reduce the pressure boost time as soon as possible. The power selection of the heating device during the process of adding water multiple times will be introduced below.

[0131] Step S321, determine whether the count value is greater than 1.

[0132] Determining whether the count value is greater than 1 is to determine whether it is the first water addition or subsequent water additions. The greater the power of the heating device, the faster the water evaporates and the faster the pressure rises. After the first water addition, the pressure in the cooking cavity 300 just starts to rise from a very low state, and during the subsequent water addition process, the cooking has experienced more than one pressure boost and has a relatively high pressure. Moreover, the later it is, the higher the pressure in the cooking cavity 300 will be. That is, the first water addition requires the fastest pressure boost, while during the subsequent water addition process, the pressure boost is relatively slow. Therefore, the heating powers required for the first water addition and subsequent water additions are inconsistent, so it is necessary to determine whether it is the first water addition or subsequent water additions.

[0133] Step S322, if the count value is 1, control the heating device to operate at full power.

[0134] Before the first water addition, since the cooking cavity 300 is dry burned and there is no water vapor, the pressure in the cooking cavity 300 is relatively low. The count value being 1 indicates that this is the first water addition at this time. Therefore, in order to enable the cooking cavity 300 to quickly boost pressure under the condition of very low pressure, it is necessary to control the heating device to operate at full power and heat the cooking cavity 300 with the maximum power to make the water evaporate quickly.

[0135] Step S323, if the count value is greater than 1, obtain the third air pressure value in the cooking cavity 300 after the water addition is completed, and determine the operating power of the heating device according to the third air pressure value.

[0136] If the count value is greater than 1, it indicates that water has been added to the cooking cavity 300 before, and thus there is already a certain pressure in the cooking cavity 300. If full-power heating is directly adopted after the water addition is completed, it may cause the pressure in the cooking cavity 300 to exceed the preset pressure value. Therefore, it is necessary to first obtain the third air pressure value in the cooking cavity 300 and select full-power heating or power-adjusted heating according to the third air pressure value.

[0137] If, after the water addition, the third air pressure value is relatively large, it means that the air pressure value in the cooking cavity 300 is relatively close to the target air pressure value, and small-power heating can be selected. If the third air pressure value is relatively small, it means that the current air pressure value in the cooking cavity 300 is far from the target air pressure value. In order to achieve rapid pressure increase, high-power heating is required to reduce the pressure increase time. That is, when the third air pressure value is small, full-power heating can be selected to rapidly increase the air pressure in the cooking cavity 300, while when the third air pressure value is large, power-adjusted heating can be used to slowly increase the air pressure in the cooking cavity 300.

[0138] Specifically, the larger the third air pressure value, the smaller the heating power of the heating device, and the smaller the third air pressure value, the larger the heating power of the heating device.

[0139] Step S330, obtain the second air pressure value of the cooking cavity 300 in real time during the heating process of the heating device.

[0140] During the water addition process of the cooking cavity 300, when the pressure rises to a certain value, water can be added once to reduce the pressure in the cooking cavity 300 to a certain extent, and then the pressure is restored and continues to rise through the heating of the heating device. Therefore, it is necessary to obtain the second air pressure value of the cooking cavity 300 to judge the timing of water addition. The second air pressure value is obtained in real time, and the interval time for obtaining the second air pressure value can be set, and it can be obtained once every first preset time.

[0141] Step S340, judge whether the second air pressure value is greater than the preset pressure value; where the preset pressure value and the preset capacity are both related to the count value.

[0142] The preset pressure value is related to the count value. That is to say, each water addition has a corresponding preset pressure value. After each water addition is completed, the corresponding preset pressure value is selected for comparison. For example, the preset pressure value corresponding to the second water addition is x, and the preset pressure value corresponding to the third water addition is y. After the second water addition is completed, judge whether the second air pressure value is greater than x, and after the third water addition is completed, judge whether the third air pressure value is greater than y.

[0143] If the second air pressure value is greater than or equal to the preset pressure value, repeat the step of controlling the water injection module 400 to add the preset capacity of water into the cooking cavity 300.

[0144] That is, the preset pressure value is the trigger condition for each water addition. Only when the second air pressure value is greater than or equal to the preset pressure value, the corresponding number of water additions is performed.

[0145] For example, set the preset pressure value corresponding to the second water addition as x, and set the preset pressure value corresponding to the third water addition as y. After the control water injection module 400 adds water with a preset volume into the cooking cavity 300, the pressure in the cooking cavity 300 rises. When the second air pressure value is greater than or equal to x, the step of controlling the water injection module 400 to add water with a preset volume into the cooking cavity 300 is repeatedly executed. At this time, it is the second water addition, the count value is 2, and the amount of water added is the preset volume corresponding to the second water addition; the heating device continuously heats, and the pressure in the cooking cavity 300 continues to rise. When the second air pressure value is greater than or equal to y, the step of controlling the water injection module 400 to add water with a preset volume into the cooking cavity 300 is repeatedly executed again. At this time, it is the third water addition, the count value is 3, and the amount of water added is the preset volume corresponding to the third water addition, and so on. The method of exiting the repeated water addition step is introduced below.

[0146] In some embodiments, in combination with Figure 7 , step S300 may further include step S351, step S352 and step S353.

[0147] Step S351, determine the total amount of water added by the current water injection module 400 according to the count value and the preset volume corresponding to the count value.

[0148] The count value is the number of water additions. By adding up the amount of water added each time, the total amount of water added by the water injection module 400 can be obtained. By comparing the total amount of water added with the target volume, it can be judged whether the water addition is completed, and thus the condition for exiting the repeated water addition step can be obtained.

[0149] Step S352, judge whether the total amount of water added is greater than or equal to the target volume.

[0150] If the total amount of water added is greater than or equal to the target volume, it indicates that the water addition is completed, and the repeated water addition step can be exited; if the total amount of water added is less than or equal to the target volume, it indicates that the water addition is not completed, and the step of continuing to control the water injection module 400 to add water with a preset volume into the cooking cavity 300 needs to be executed. Therefore, it is necessary to judge whether the total amount of water added is greater than or equal to the target volume to judge the timing of exiting the repeated water addition step.

[0151] If the total amount of water added is greater than or equal to the target volume, obtain the air pressure value of the cooking cavity 300; if the air pressure value of the cooking cavity 300 reaches the target pressure value, perform the steps of maintaining pressure and / or exhausting air for the cooking cavity 300.

[0152] The target pressure value is the pressure value that needs to be finally reached during the cooking process. At the target pressure value, cooking can be completed. When the total water addition amount is greater than or equal to the target capacity, it means that the water of the target capacity has been added. At this time, the repeated water addition step can be exited, and the air pressure value of the cooking cavity 300 can be obtained. Of course, after the last water addition is completed, it is necessary to heat for a period of time to continue boosting the pressure until the air pressure value of the cooking cavity 300 reaches the target pressure value. At this time, the cooking cavity 300 is pressurized and / or exhausted to end the cooking.

[0153] If the total water addition amount is less than the target capacity, the step of continuing to control the water injection module 400 to add a preset capacity of water into the cooking cavity 300 is executed.

[0154] If the total water addition amount is less than the target capacity, the water addition step is not completed. Therefore, the step of continuing to control the water injection module 400 to add a preset capacity of water into the cooking cavity 300 is executed.

[0155] In some embodiments, the preset capacity with a count value of 1 is less than the preset capacities corresponding to other count values; the larger the count value, the larger the preset capacity; the larger the count value, the larger the preset pressure value.

[0156] Before the first water addition, since the cooking cavity 300 is dry burned and there is no water vapor, the pressure in the cooking cavity 300 is relatively low. A count value of 1 indicates that this is the first water addition. Therefore, in order to make the cooking cavity 300 boost the pressure as quickly as possible under the condition of low pressure, the amount of the first water addition needs to be the least, so that the water can evaporate faster and the pressure can rise faster. The larger the count value, that is, the later the water addition times. In the subsequent water addition times, since there is already water vapor in the cooking cavity 300, that is, the cooking cavity 300 has been boosted continuously, at this time, the pressure boost speed can be appropriately slowed down, and the core requirement changes from quickly boosting the pressure to fully cooking. Therefore, the amount of water added later can be more. Since during the cooking process of the cooking cavity 300, the pressure gradually rises until it reaches the target pressure value, the later the water addition times, the closer it is to the target pressure value. Therefore, the later the water addition times, the corresponding trigger condition, that is, the preset pressure value will be larger.

[0157] It should be noted that during the multiple water addition processes, the pressure in the cooking cavity 300 does not continuously rise. Each time water is added, the temperature in the cooking cavity 300 will decrease a little, and thus the pressure will also decrease. It is necessary to continuously heat the water in the cooking cavity 300 through the heating device to achieve pressure boost.

[0158] Step S400, obtain the air pressure value of the cooking cavity 300.

[0159] After performing a boosting operation on the cooking chamber 300 in step S300, it is necessary to determine whether the air pressure in the cooking chamber 300 reaches the target air pressure value. Therefore, the air pressure value of the cooking chamber 300 is required. The air pressure value of the cooking chamber 300 can be obtained according to the temperature value of the cooking chamber 300, or a pressure sensor can be set in the cooking chamber 300 to directly detect it.

[0160] Step S500: If the air pressure value in the cooking chamber 300 reaches the target pressure value, perform pressure holding and / or exhaust on the cooking chamber 300.

[0161] That is, after the air pressure value in the cooking chamber 300 reaches the target pressure value, at least one of the steps of pressure holding and exhaust can be selected. After the air pressure value in the cooking chamber 300 reaches the target pressure value, if the food is not cooked yet at this time, pressure holding can be selected to continue cooking the food. If the food is already cooked at this time, exhaust can be directly selected; or, if the target pressure value is relatively low, exhaust can also be not selected, and it can be selected according to the actual situation without limitation.

[0162] Combined with Figure 8 , the following introduces the steps of performing both pressure holding and exhaust:

[0163] Step S500 may include step S510 and step S520.

[0164] Step S510: Control the air pressure value in the cooking chamber 300 to maintain at the target pressure value, and obtain the pressure holding time maintained at the target pressure value.

[0165] Since the air pressure value in the cooking chamber 300 has reached the target pressure value, control the air pressure value in the cooking chamber 300 to maintain at the target pressure value to achieve pressure holding. If the food is almost cooked, the pressure holding time can be set shorter; if the food is still very raw, the pressure holding time can be set longer to increase the cooking time.

[0166] Step S520: If the pressure holding time is greater than or equal to the set time, control the cooking chamber 300 to release pressure.

[0167] When the pressure holding time is greater than or equal to the set time, it means that the food is cooked at this time, so the cooking chamber 300 can be controlled to release pressure to end the cooking.
