[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0025] As Figure 1 shown, Figure 1 It is a flowchart of the cooking control method of the electric pressure cooker provided by the embodiment of the present invention. The cooking control method of the electric pressure cooker provided by the embodiment of the present invention includes the following steps S101 to S103.

[0026] S101. Detect whether the lid of the electric pressure cooker is opened.

[0027] In some embodiments, each cooking process completed by the electric pressure cooker may include a pressure boosting stage, a pressure holding stage, a pressure releasing stage, and a sauce thickening stage that is only carried out after the pressure releasing ends. Since the lid of the electric pressure cooker can be opened after the pressure releasing ends, however, whether the user will open the lid of the electric pressure cooker and when to open the lid of the electric pressure cooker are both uncertain after the pressure releasing of the electric pressure cooker ends. Therefore, in some embodiments, before step S101, it further includes: in response to a signal indicating that the pressure releasing of the electric pressure cooker ends, outputting a prompt message for prompting the user to open the lid of the electric pressure cooker; when the electric pressure cooker outputs the prompt message, triggering to start detecting whether the lid of the electric pressure cooker is opened, that is, triggering to execute the above step S101: detecting whether the lid of the electric pressure cooker is opened.

[0028] Through the above embodiments, it is realized that after the pressure releasing of the electric pressure cooker ends, a prompt message for prompting the user to open the lid of the electric pressure cooker is immediately output, so that the user can be timely reminded to open the lid of the electric pressure cooker after the pressure releasing of the electric pressure cooker ends.

[0029] Different from the above embodiments, after the pressure releasing of the electric pressure cooker ends, the user is not immediately prompted to open the lid, but after the electric pressure cooker thickens the sauce for a period of time in the lid-closed state, the user is then prompted to open the lid. Therefore, in some other embodiments, before step S101, it further includes: in response to a signal indicating that the pressure releasing of the electric pressure cooker ends, controlling the exhaust device of the electric pressure cooker to open and controlling the electric pressure cooker to operate at a second heating power so that the electric pressure cooker thickens the sauce in the lid-closed state; during the process of the electric pressure cooker operating at the second heating power, if it is detected that the working parameters of the electric pressure cooker meet the start condition for opening the lid and thickening the sauce, outputting a prompt message for prompting the user to open the lid of the electric pressure cooker; and when the prompt message is output, triggering to start detecting whether the lid of the electric pressure cooker is opened, that is, executing the above step S101: detecting whether the lid of the electric pressure cooker is opened.

[0030] In some embodiments, the electric pressure cooker may output a prompt message for prompting the user to open the lid of the electric pressure cooker in a way such as display and / or sound to prompt the user to open the lid. It can be understood that the second heating power can be a fixed power value, or a variable power value that increases with the passage of time of the electric pressure cooker thickening the sauce in the lid-closed state or the rise of the bottom temperature.

[0031] In some embodiments, detecting whether the working parameters of the electric pressure cooker meet the conditions for starting to open the lid and collect juice during the operation of the electric pressure cooker at the second heating power can include: detecting whether the time for which the electric pressure cooker runs at the second heating power is greater than a preset time, and when it is detected that the time for which the electric pressure cooker runs at the second heating power is greater than the preset time, it is characterized that the working parameters of the electric pressure cooker meet the conditions for starting to open the lid and collect juice, wherein the preset time can be set to a time value that is less than the time for closing the lid and collecting juice required for the current cooking, thereby reserving a portion of water and time for collecting juice after opening the lid.

[0032] S102: If it is detected that the electric pressure cooker has its lid opened, control the electric pressure cooker to operate at a first heating power, so that the electric pressure cooker can collect juice with its lid opened.

[0033] It is understandable that the first heating power may be a fixed power value, or a variable power value that increases as the time for the electric pressure cooker to collect juice increases with the lid open or the temperature of the bottom of the pot rises.

[0034] In some embodiments, the second heating power is less than the first heating power. This is because when the electric pressure cooker is in the open state, the ingredients in the cooking cavity can be in direct contact with the air, and there is no fear of the soup in the cooking cavity overflowing. Therefore, the first heating power can use a higher power value than the second heating power to speed up the juice collection speed when the lid is open. Speeding up the juice collection speed can shorten the cooking time of the entire cooking process, and a large heating power is more conducive to flavor enhancement. When the electric pressure cooker is in the closed state, it can only be vented through the open exhaust device. Therefore, when the electric pressure cooker is in the closed state, if the heating power is too high, there will be a risk of overflow. Therefore, when collecting juice when the electric pressure cooker is in the closed state, a second heating power that is smaller than the first heating power needs to be used.

[0035] It should be noted that the first heating power may be measured when the electric pressure cooker is in an open lid state, so as to prevent the soup in the cooking chamber of the electric pressure cooker from overflowing. The second heating power may be measured when the electric pressure cooker is in a closed lid state and the exhaust device is at the maximum opening, so as to prevent the soup in the cooking chamber of the electric pressure cooker from overflowing.

[0036] S103, when the electric pressure cooker is running at the first heating power, if it is detected that the working parameters of the electric pressure cooker meet the condition of opening the lid and collecting juice, the electric pressure cooker is controlled to stop heating.

[0037] In step S103, it is detected whether the working parameters of the electric pressure cooker meet the conditions for ending the juice collection by opening the lid. If it is detected that the working parameters of the electric pressure cooker meet the conditions for ending the juice collection by opening the lid, the electric pressure cooker is controlled to stop heating. At this point, the juice collection stage of the electric pressure cooker ends.

[0038] Regarding the detection in step S103 of whether the operating parameters of the electric pressure cooker meet the conditions for ending the opening and reducing the juice, according to different operating parameters, there can be multiple different implementation manners. Some implementation manners are given below:

[0039] In some implementation manners, the operating parameters of the electric pressure cooker may only include the juice-reducing duration of the electric pressure cooker. During the process of the electric pressure cooker operating at the first heating power, it is detected whether the duration of the electric pressure cooker operating at the first heating power is greater than the opening and juice-reducing duration required for the current cooking. If the duration of the electric pressure cooker operating at the first heating power is greater than the opening and juice-reducing duration, it indicates that the operating parameters of the electric pressure cooker meet the conditions for ending the opening and juice-reducing.

[0040] In some other implementation manners, the operating parameters of the electric pressure cooker may only include the bottom temperature of the electric pressure cooker. During the process of the electric pressure cooker operating at the first heating power, it is detected whether the bottom temperature of the electric pressure cooker rises to the first temperature threshold. When it is detected that the bottom temperature rises to the first temperature threshold, it indicates that the operating parameters of the electric pressure cooker meet the conditions for ending the opening and juice-reducing.

[0041] In some other implementation manners, the operating parameters of the electric pressure cooker may include both the juice-reducing duration and the bottom temperature of the electric pressure cooker. During the process of the electric pressure cooker operating at the first heating power, it is detected whether the duration of the electric pressure cooker operating at the first heating power is greater than the opening and juice-reducing duration required for the current cooking and whether the bottom temperature of the electric pressure cooker rises to the first temperature threshold. If it is detected that the duration of the electric pressure cooker operating at the first heating power is greater than the opening and juice-reducing duration or the bottom temperature rises to the first temperature threshold, it indicates that the operating parameters of the electric pressure cooker meet the conditions for ending the opening and juice-reducing. That is to say, when any one of the following two conditions is detected to be reached first, it is determined that the operating parameters of the electric pressure cooker meet the conditions for ending the opening and juice-reducing: Condition 1, the duration of the electric pressure cooker operating at the first heating power is greater than the opening and juice-reducing duration; Condition 2, the bottom temperature of the electric pressure cooker rises to the first temperature threshold. By combining the above two conditions to judge whether to end the opening and juice-reducing, the end of the opening and juice-reducing can be controlled more accurately.

[0042] In some implementation manners, the first temperature threshold can be within the range of 115 - 135 °C. For example, it can be 115 °C, 125 °C or 135 °C.

[0043] Since the user may not be able to obtain the prompt information in time after the electric pressure cooker outputs the prompt information, or even if the user obtains the prompt information, he or she may not open the lid of the electric pressure cooker in time, in order to avoid the electric pressure cooker being unable to enter the juice collection stage due to the user not opening the lid of the electric pressure cooker for a long time, in some embodiments, it is detected whether the lid of the electric pressure cooker is opened within a preset limit time after the prompt information is output; if the lid of the electric pressure cooker is detected to be opened within the preset limit time after the prompt information is output, the juice collection control logic of the electric pressure cooker in the lid-open state is executed, that is, the above steps S102~S103 are executed; if the lid of the electric pressure cooker is not detected to be opened within the preset limit time after the prompt information is output, the juice collection control logic of the electric pressure cooker in the lid-closed state is executed, that is, the following steps S102'~S103' are executed.

[0044] In some implementations, the preset limit time can be set according to actual needs, and can be set to a time value within 0 to 5 minutes, for example, can be set to 1 minute, 2 minutes, 3 minutes, 4 minutes or 5 minutes.

[0045] Through the above implementation, two different juice collection control logics can be adopted according to whether the electric pressure cooker has its lid opened. When the user has opened the lid of the electric pressure cooker, the juice can be collected faster. Even if the user has not opened the lid of the electric pressure cooker, the electric pressure cooker can collect juice with its lid closed.

[0046] S102': If the opening of the lid of the electric pressure cooker is not detected within the preset time limit, the exhaust device of the electric pressure cooker is controlled to open and the electric pressure cooker is controlled to operate at the second heating power, so that the electric pressure cooker can collect juice with the lid closed.

[0047] In some embodiments, the exhaust device may be an exhaust valve disposed on the lid of the electric pressure cooker, and controlling the exhaust device of the electric pressure cooker to open may be: controlling the exhaust valve to be continuously opened at the maximum opening, so that the second heating power used by the electric pressure cooker in the lid closed state is as large as possible, so as to speed up the juice collection speed in the lid closed state.

[0048] S103': when the electric pressure cooker is running at the second heating power, if the working parameters of the electric pressure cooker meet the condition of closing the lid and collecting the juice, the electric pressure cooker is controlled to stop heating.

[0049] In step S103', when the electric pressure cooker is running at the second heating power, it is detected whether the working parameters of the electric pressure cooker meet the condition for closing the lid and collecting juice. When it is detected that the working parameters of the electric pressure cooker meet the condition for closing the lid and collecting juice, the electric pressure cooker is controlled to stop heating. At this point, the juice collecting stage ends, and the subsequent user will not collect juice even if he opens the lid of the electric pressure cooker.

[0050] It can be understood that during the process of the electric pressure cooker operating at the second heating power in step S103’, there is a possibility that the user performs an operation of opening the lid of the electric pressure cooker. In response to this situation, the present invention can adopt various implementation manners to deal with it:

[0051] In some implementation manners, during the process of the electric pressure cooker operating at the second heating power in step S103’, it is no longer necessary to continuously detect whether the lid of the electric pressure cooker is opened; such that even if the user performs an operation of opening the lid of the electric pressure cooker, it will not change the heating power used for sauce collection, but continue to operate at the second heating power in the lid-open state until the working parameters of the electric pressure cooker meet the lid-closed sauce collection end condition, and then control the electric pressure cooker to stop heating.

[0052] In other implementation manners, during the process of the electric pressure cooker operating at the second heating power in step S103’, continue to detect whether the lid of the electric pressure cooker is opened; if it is detected that the lid of the electric pressure cooker is opened, control the electric pressure cooker to switch from the second heating power to the first heating power and continue to operate; during the process of the electric pressure cooker switching to continue operating at the first heating power, detect whether the working parameters of the electric pressure cooker meet the lid-open sauce collection end condition, and if it is detected that the working parameters of the electric pressure cooker meet the lid-open sauce collection end condition, control the electric pressure cooker to stop heating. Thus, the sauce collection stage ends.

[0053] Regarding detecting whether the working parameters of the electric pressure cooker meet the lid-closed sauce collection end condition in step S103’, according to different working parameters, there can be various different implementation manners. Some implementation manners are given below:

[0054] In some implementation manners, if the working parameters of the electric pressure cooker only include the sauce collection duration of the electric pressure cooker, during the process of the electric pressure cooker operating at the second heating power, detect whether the duration of the electric pressure cooker operating at the second heating power is greater than the lid-closed sauce collection duration required for the current cooking; if the duration of the electric pressure cooker operating at the second heating power is greater than the lid-closed sauce collection duration, it indicates that the working parameters of the electric pressure cooker meet the lid-closed sauce collection end condition.

[0055] In other implementation manners, if the working parameters of the electric pressure cooker only include the bottom temperature of the electric pressure cooker, during the process of the electric pressure cooker operating at the second heating power, detect whether the bottom temperature of the electric pressure cooker rises to the second temperature threshold. When the bottom temperature rises to the second temperature threshold, it indicates that the working parameters of the electric pressure cooker meet the lid-closed sauce collection end condition.

[0056] In some other embodiments, if the operating parameters of the electric pressure cooker simultaneously include the juice-concentrating duration and the bottom temperature of the electric pressure cooker, during the operation of the electric pressure cooker at the second heating power, it is detected whether the duration of the operation of the electric pressure cooker at the second heating power is greater than the juice-concentrating duration with the lid closed required for the current cooking and whether the bottom temperature of the electric pressure cooker rises to the second temperature threshold. If it is detected that the duration of the operation of the electric pressure cooker at the second heating power is greater than the juice-concentrating duration with the lid closed or the bottom temperature rises to the second temperature threshold, it is characterized that the operating parameters of the electric pressure cooker meet the end condition of juice-concentrating with the lid closed. That is to say, when it is detected that any one of the following two conditions is reached first, it is determined that the operating parameters of the electric pressure cooker meet the end condition of juice-concentrating with the lid closed: Condition 1: The duration of the operation of the electric pressure cooker at the second heating power is greater than the juice-concentrating duration with the lid closed; Condition 2: The bottom temperature rises to the second temperature threshold. By combining the above two conditions to determine whether to end the juice-concentrating with the lid closed, the end of the juice-concentrating with the lid closed can be controlled more accurately.

[0057] In some embodiments, the second temperature threshold can be in the range of 115-135°C, and the second temperature threshold can be equal to the first temperature threshold. Since the heating power used for juice-concentrating with the lid closed in the electric pressure cooker is relatively small and the thermal inertia is small, the second temperature threshold can be a value greater than the first temperature threshold in the range of 115-135°C. For example, the first temperature threshold is set to 125°C and the second temperature threshold is set to 130°C to improve the juice-concentrating effect with the lid closed and make the juice-concentrating with the lid closed more flavorful.

[0058] In some embodiments, the electric pressure cooker may further include an opening / closing lid detection device that generates different electrical signals corresponding to the opening and closing of the lid of the electric pressure cooker. When the electric pressure cooker includes the opening / closing lid detection device, if the user performs an opening lid operation on the electric pressure cooker, the opening / closing lid detection device will generate an electrical signal indicating the opening of the lid of the electric pressure cooker. If the user performs a closing lid operation on the electric pressure cooker, the opening / closing lid detection device will generate an electrical signal indicating the closing of the lid of the electric pressure cooker. When the electric pressure cooker includes the opening / closing lid detection device, the step of detecting whether the lid of the electric pressure cooker is opened may include: detecting whether the opening / closing lid detection device generates an electrical signal indicating the opening of the lid of the electric pressure cooker; if so, it is characterized that the user has performed an opening lid operation on the electric pressure cooker, and thus, it can be determined that the lid of the electric pressure cooker is opened.

[0059] In some embodiments, the opening lid juice-concentrating duration and the closing lid juice-concentrating duration required for the current cooking can be fixed durations measured in advance, and the opening lid juice-concentrating duration is less than the closing lid juice-concentrating duration. That is to say, during different cooking processes of the electric pressure cooker, the opening lid juice-concentrating duration and the closing lid juice-concentrating duration used will not change and will not vary due to the amount of water added in the current cooking.

[0060] In some other embodiments, to achieve more precise control of the sauce-reducing effect, the actual pressure-boosting duration of the electric pressure cooker during the current cooking or the menu information selected by the user for the current cooking can be obtained. Based on the actual pressure-boosting duration or the menu information, the lid-opening sauce-reducing duration and the lid-covering sauce-reducing duration required by the electric pressure cooker during the current cooking can be determined.

[0061] It can be understood that the more water is added to the cooking cavity for the current cooking, the more time the electric pressure cooker needs during the pressure-boosting stage. Therefore, the pressure-boosting duration used by the electric pressure cooker during the pressure-boosting stage can reflect the amount of soup in the cooking cavity that needs to be reduced. The longer the pressure-boosting duration used, the more soup there is in the cooking cavity, and a longer sauce-reducing time is required to achieve a better sauce-reducing state and make the ingredients more flavorful. Therefore, based on the actual pressure-boosting duration of the current cooking, the lid-opening sauce-reducing duration and the lid-covering sauce-reducing duration more suitable for the current cooking can be set, which can more accurately and reasonably control the sauce-reducing duration, making the ingredients more flavorful after sauce reduction without over-sauce reduction. The menu information selected by the user for the current cooking includes various recommended ingredient amounts for the current cooking, including the recommended water addition amount. Therefore, based on the menu information selected by the user, the lid-opening sauce-reducing duration and the lid-covering sauce-reducing duration suitable for the current cooking can also be determined.

[0062] It should be noted that both the lid-opening sauce-reducing duration and the lid-covering sauce-reducing duration required by the electric pressure cooker during the current cooking determined based on the actual pressure-boosting duration are positively correlated with the actual pressure-boosting duration used by the electric pressure cooker during the pressure-boosting stage, and the lid-opening sauce-reducing duration required for the current cooking is less than the lid-covering sauce-reducing duration required for the current cooking. In some embodiments, the actual pressure-boosting duration of the electric pressure cooker during the pressure-boosting stage of the current cooking is recorded; based on the first preset positive correlation relationship between the pressure-boosting duration and the lid-opening sauce-reducing duration, the lid-opening sauce-reducing duration required for the current cooking is determined; based on the second preset positive correlation relationship between the pressure-boosting duration and the lid-covering sauce-reducing duration, the lid-covering sauce-reducing duration required for the current cooking is determined.

[0063] For example, the first preset positive correlation relationship and the second preset positive correlation relationship can correspond to the relationship that the lid-opening sauce-reducing duration and the lid-covering sauce-reducing duration increase linearly as the pressure-boosting duration increases. Thus, based on the linearly increasing relationship and the actual pressure-boosting duration of the electric pressure cooker during the current cooking, the lid-covering sauce-reducing duration and the lid-opening sauce-reducing duration required for the current cooking are determined.

[0064] For another example, multiple pressure-boosting duration intervals can be pre-divided. Each pressure-boosting time interval corresponds to a lid-opening sauce-reducing duration and a lid-covering sauce-reducing duration. Based on the pressure-boosting duration interval in which the actual pressure-boosting duration of the current cooking is located, the corresponding lid-opening sauce-reducing duration is determined as the lid-opening sauce-reducing duration required for the current cooking, and based on the pressure-boosting duration interval in which the actual pressure-boosting duration interval of the current cooking is located, the corresponding lid-covering sauce-reducing duration is determined as the lid-covering sauce-reducing duration required for the current cooking.

[0065] Determine the lid-open simmering duration and lid-closed simmering duration suitable for the current cooking according to the menu information selected by the user, which may include: determining the recommended water addition amount for the current cooking according to the menu information, and determining the lid-open simmering duration and lid-closed simmering duration required by the electric pressure cooker for the current cooking according to the recommended water addition amount. The specific implementation process is similar to the above process of determining the lid-open simmering duration and lid-closed simmering duration required by the electric pressure cooker for the current cooking according to the actual pressure boosting duration. For the sake of simplicity of the specification, it will not be elaborated here.

[0066] To facilitate the understanding of the technical solutions provided by the embodiments of the present invention, the following is an example for illustration, but it does not limit the present invention:

[0067] Taking the current cooking of the electric pressure cooker as cooking braised pork as an example, after the electric pressure cooker finishes pressure relief, output a prompt message for prompting the user to open the lid. While outputting the prompt message, start detecting whether the user opens the lid for 5 minutes continuously.
