Technical Field

[0001] The present invention relates to the technical field of cooking equipment, and in particular to a method for displaying a pressure reduction countdown of a cooking device, a computer-readable storage medium, a device for displaying a pressure reduction countdown of a cooking device, and a cooking device. Background Art

[0002] At present, after cooking is completed, the pressure cooker products of the related art cannot be opened immediately due to the pressure inside the pot. Therefore, it is usually necessary to reduce the pressure. However, the problem with the related art is that some products only display special symbols during the pressure reduction process, while other products only display the insulation time during the pressure reduction process. This makes it impossible for users to know whether the pressure reduction process has ended, resulting in users being unable to easily open the lid, which greatly reduces the user experience. Summary of the Invention

[0003] The present invention aims to at least partially address one of the technical problems in the related art. To this end, a first object of the present invention is to provide a method for displaying a pressure drop countdown in a cooking device. The method can retrieve a predicted pressure drop time from a pressure drop time database and display a countdown based on different function selection instructions, the amount of food being cooked, and the pressure within the pot. This method enables a countdown display of the pressure drop process in the cooking device while ensuring countdown accuracy. Furthermore, the method eliminates the need to modify the existing structure of the cooking device and has broad applicability.

[0004] A second object of the present invention is to provide a computer-readable storage medium.

[0005] A third object of the present invention is to provide a pressure reduction countdown display device for cooking equipment.

[0006] A fourth object of the present invention is to provide a cooking device.

[0007] To achieve the above-mentioned purpose, the first aspect of the present invention proposes a method for displaying a pressure reduction countdown for a cooking device, which includes: obtaining a function selection instruction of the cooking device, and obtaining the amount of cooked food of the cooking device before the cooking stage is started, and obtaining the pressure in the pot of the cooking device at the end of the cooking stage; obtaining a predicted pressure reduction time from a pressure reduction time database according to the function selection instruction, the amount of cooked food and the pressure in the pot, wherein the pressure reduction time database stores multiple sets of mapping relationships between the amount of cooked food and the pressure in the pot and the predicted pressure reduction time; and performing a countdown display according to the predicted pressure reduction time.

[0008] According to an embodiment of the present invention, a method for displaying a pressure drop countdown for a cooking device obtains a function selection instruction for the cooking device, obtains the amount of food being cooked by the cooking device before a cooking phase begins, and obtains the pressure within the pot of the cooking device at the end of the cooking phase. Based on the function selection instruction, the amount of food being cooked, and the pressure within the pot, a predicted pressure drop time is obtained from a pressure drop time database, wherein the pressure drop time database stores a mapping relationship between multiple sets of food amounts, pot pressures, and predicted pressure drop times. A countdown display is then performed based on the predicted pressure drop time. Thus, by obtaining a predicted pressure drop time from the pressure drop time database and displaying a countdown based on different function selection instructions, food amounts, and pot pressures, a countdown display of the pressure drop process of the cooking device is implemented, ensuring countdown accuracy without requiring changes to the existing structure of the cooking device, thus achieving wide applicability.

[0009] In addition, the method for displaying the voltage reduction countdown of the cooking device according to the above embodiment of the present invention may also have the following additional technical features:

[0010] According to one embodiment of the present invention, obtaining the amount of cooked food by the cooking device before the cooking stage is started includes: obtaining the time taken to heat the food to be cooked to a preset temperature threshold or a preset pressure threshold, and determining the amount of cooked food by the cooking device based on the time taken, or heating the food to be cooked for a preset time to obtain a heating rate of the food to be cooked, and determining the amount of cooked food by the cooking device based on the heating rate.

[0011] According to one embodiment of the present invention, the method further includes: when the countdown has a preset time threshold remaining, determining whether the pressure in the pot of the cooking device has reached a preset pressure threshold; if the pressure in the pot of the cooking device has reached the preset pressure threshold, then when the countdown reaches the predicted pressure reduction time, controlling the cooking device to end the pressure reduction.

[0012] According to one embodiment of the present invention, the cooking device includes an auxiliary pressure reducing unit, which is used to reduce the pressure in the pot of the cooking device. The method also includes: when the countdown has a preset time threshold remaining, judging whether the pressure in the pot of the cooking device has reached a preset pressure threshold; if the pressure in the pot of the cooking device has not reached the preset pressure threshold, adjusting the pressure reduction speed of the auxiliary pressure reducing unit so that the pressure in the pot of the cooking device reaches the preset pressure threshold when the countdown reaches the predicted pressure reduction time.

[0013] According to one embodiment of the present invention, the method further includes: when the countdown reaches the predicted pressure reduction time and the pressure in the pot of the cooking device does not reach a preset pressure threshold, controlling the cooking device to issue a high pressure warning.

[0014] According to one embodiment of the present invention, the method further includes: acquiring the current ambient temperature of the cooking device; correcting the predicted pressure drop time according to the current ambient temperature, and performing a countdown display according to the corrected predicted pressure drop time.

[0015] According to one embodiment of the present invention, after controlling the cooking device to end the pressure reduction, the method further includes: obtaining the actual pressure reduction time of the cooking device; establishing a new mapping relationship between the actual pressure reduction time and the function selection instruction, the amount of cooked food and the pressure in the pot, and updating the new mapping relationship to the pressure reduction time database.

[0016] In order to achieve the above-mentioned purpose, the second aspect of the present invention proposes a computer-readable storage medium, on which a pressure reduction countdown display program for a cooking device is stored. When the pressure reduction countdown display program for the cooking device is executed by a processor, the pressure reduction countdown display method for the cooking device of the above-mentioned embodiment of the present invention is implemented.

[0017] According to the computer-readable storage medium of an embodiment of the present invention, a processor executes a pressure reduction countdown display program for a cooking device stored thereon, and can obtain a predicted pressure reduction time from a pressure reduction time database and perform a countdown display according to different function selection instructions, the amount of food to be cooked, and the pressure in the pot. Thus, a countdown display of the pressure reduction process of the cooking device is realized, and the accuracy of the countdown is ensured. At the same time, there is no need to change the existing structure of the cooking device, and the applicability is wide.

[0018] To achieve the above-mentioned purpose, the third aspect of the present invention proposes a pressure reduction countdown display device for a cooking device, comprising: a first acquisition module for acquiring a function selection instruction of the cooking device; a second acquisition module for acquiring the amount of cooked food of the cooking device before the cooking stage is started; a third acquisition module for acquiring the pressure in the pot of the cooking device at the end of the cooking stage; a control module for acquiring the predicted pressure reduction time from a pressure reduction time database according to the function selection instruction, the amount of cooked food and the pressure in the pot, and performing a countdown display according to the predicted pressure reduction time, wherein the pressure reduction time database stores a plurality of mapping relationships between the amount of cooked food and the pressure in the pot and the predicted pressure reduction time.

[0019] According to an embodiment of the present invention, a pressure reduction countdown display device for a cooking device uses a first acquisition module to obtain a function selection instruction for the cooking device, a second acquisition module to obtain the amount of food being cooked by the cooking device before the cooking phase begins, and a third acquisition module to obtain the pressure within the pot of the cooking device at the end of the cooking phase. Then, a control module retrieves a predicted pressure reduction time from a pressure reduction time database based on the function selection instruction, the amount of food being cooked, and the pressure within the pot, and displays a countdown based on the predicted pressure reduction time. The pressure reduction time database stores multiple mappings between the amount of food being cooked, the pressure within the pot, and the predicted pressure reduction time. Thus, according to different function selection instructions, the amount of food being cooked, and the pressure within the pot, the predicted pressure reduction time is retrieved from the pressure reduction time database and displayed as a countdown. This allows for a countdown display of the pressure reduction process of the cooking device while ensuring countdown accuracy. This also eliminates the need to modify the existing structure of the cooking device, resulting in a wide range of applicability.

At the same time, there is no need to change the existing structure of the cooking device, and the applicability is wide.

[0029] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0030] The following describes a method for displaying a voltage reduction countdown for a cooking device, a computer-readable storage medium, a device for displaying a voltage reduction countdown for a cooking device, and a cooking device according to embodiments of the present invention with reference to the accompanying drawings.

[0031] Figure 1 4 is a flow chart of a method for displaying a pressure reduction countdown for a cooking device according to an embodiment of the present invention.

[0032] Specifically, if Figure 1 As shown, in some embodiments of the present invention, a method for displaying a pressure reduction countdown of a cooking device includes:

[0033] S101, obtaining a function selection instruction of a cooking device, obtaining the amount of food cooked by the cooking device before a cooking phase is started, and obtaining the pressure in the pot of the cooking device at the end of the cooking phase.

[0034] Specifically, in some embodiments of the present invention, a function selection instruction of the cooking device may be obtained according to function information input by a user through an operation panel of the cooking device.

[0035] Furthermore, in some embodiments of the present invention, obtaining the amount of cooked food by the cooking device before the cooking stage is started includes: obtaining the time taken to heat the food to be cooked to a preset temperature threshold or a preset pressure threshold, and determining the amount of cooked food by the cooking device based on the time taken, or heating the food to be cooked for a preset time to obtain a heating rate of the food to be cooked, and determining the amount of cooked food by the cooking device based on the heating rate.

[0036] It can be understood that in this embodiment of the present invention, during the cooking process of the cooking device, the time taken for the food to be cooked to be heated to a preset temperature threshold or a preset pressure threshold can be obtained to determine the amount of food cooked by the cooking device based on the time taken, or the food to be cooked can be heated for a preset time to obtain the heating rate of the food to be cooked to determine the amount of food cooked by the cooking device based on the heating rate.

[0037] In addition, in the above-mentioned embodiments of the present invention, the amount of food cooked by the cooking device can be calculated based on the energy and thermal efficiency of the cooking device, or the amount of food cooked by the cooking device can be directly calculated based on a specific sensor (pressure sensor), or the amount of food cooked by the cooking device can be obtained based on the cooking information input by the user through the operation panel of the cooking device or the mobile terminal.

[0038] Furthermore, in this embodiment of the present invention, when the time for maintaining the target pressure of the cooking device reaches the target time threshold, it can be determined that the cooking stage of the cooking device is over. At this time, the pressure in the pot of the cooking device at the end of the cooking stage can be obtained with the help of a temperature sensor or a pressure sensor. For example, the temperature in the pot of the cooking device at the end of the cooking stage is detected by a temperature sensor, and then the pressure in the pot of the cooking device at the end of the cooking stage is calculated based on the temperature in the pot. For another example, the pressure in the pot of the cooking device at the end of the cooking stage can be directly detected by a pressure sensor.

[0039] It should be noted that, in the above-mentioned embodiment of the present invention, the pressure in the pot of the cooking device at the end of the cooking stage is usually a function default target pressure or a target pressure preset by the user.

[0040] S102, obtaining a predicted pressure reduction time from a pressure reduction time database according to the function selection instruction, the amount of food to be cooked, and the pressure in the pot, wherein the pressure reduction time database stores a mapping relationship between multiple sets of cooking food amounts, pressures in the pot, and predicted pressure reduction times.

[0041] Specifically, in this embodiment of the present invention, the predicted pressure reduction time that matches the current cooking scenario can be obtained from the pressure reduction time database according to different function selection instructions, cooking food quantity and pressure in the pot, so as to achieve accurate timing of the pressure reduction stage of the cooking equipment.

[0042] It should be noted that, in the above embodiment of the present invention, different function selection instructions correspond to different pressure reduction time databases, and different cooking food amounts and pressures correspond to different predicted pressure reduction times in the pressure reduction time database (current function selection instruction).

[0043] S103, displaying a countdown based on the predicted blood pressure reduction time.

[0044] It can be understood that in this embodiment of the present invention, the depressurization time database can be combined with the function selection instructions of the cooking device, the amount of food cooked by the cooking device before the cooking stage starts, and the pressure in the pot of the cooking device at the end of the cooking stage to realize the countdown display of the depressurization process of the cooking device and ensure the accuracy of the countdown. At the same time, there is no need to change the existing structure of the cooking device, and the applicability is wide.

[0045] In addition, in other embodiments of the present invention, the external ambient temperature of the cooking device can be obtained when the cooking device starts cooking, and a more accurate predicted pressure reduction time can be obtained by combining the external ambient temperature, function selection instructions, food cooking amount and pressure in the pot, so as to further improve the accuracy of the countdown display of the pressure reduction process of the cooking device.

[0046] Furthermore, if Figure 2 As shown, in some embodiments of the present invention, the method further includes:

[0047] S201: When the countdown reaches a preset time threshold, determine whether the pressure in the pot of the cooking device reaches a preset pressure threshold.

[0048] It should be understood that in this embodiment of the present invention, when the countdown reaches a preset time threshold, it is possible to determine whether the pressure in the pot of the cooking device has reached a preset pressure threshold to determine whether the cooking device has completed the pressure reduction in the pot, thereby ensuring the accuracy of the countdown display of the pressure reduction process.

[0049] S202: If the pressure in the pot of the cooking device reaches a preset pressure threshold, the cooking device is controlled to end the pressure reduction when the countdown reaches the predicted pressure reduction time.

[0050] Specifically, in this embodiment of the present invention, when the pressure in the pot of the cooking device reaches a preset pressure threshold, it can be judged that the cooking device has completed the pressure reduction process of the cooking stage. At this time, when the countdown reaches the predicted pressure reduction time, the cooking device can be controlled to end the pressure reduction.

[0051] It should be noted that, in the above-mentioned embodiments of the present invention, the following two situations may be included but not limited to: (1) the pressure in the pot of the cooking device reaches the preset pressure threshold, and the countdown just reaches the predicted pressure reduction time. At this time, the cooking device is controlled to end the pressure reduction; (2) the pressure in the pot of the cooking device reaches the preset pressure threshold, and the countdown has not yet reached the predicted pressure reduction time. At this time, when the countdown reaches the predicted pressure reduction time, the cooking device is controlled to end the pressure reduction.

[0052] Furthermore, in some embodiments of the present invention, the cooking device includes an auxiliary pressure reducing unit, which is used to reduce the pressure in the pot of the cooking device. The method also includes: when the countdown leaves a preset time threshold, determining whether the pressure in the pot of the cooking device reaches a preset pressure threshold, and, if the pressure in the pot of the cooking device does not reach the preset pressure threshold, adjusting the pressure reduction speed of the auxiliary pressure reducing unit so that the pressure in the pot of the cooking device reaches the preset pressure threshold when the countdown reaches the predicted pressure reduction time.

[0053] Specifically, in this embodiment of the present invention, when the countdown has a preset time threshold remaining and the pressure in the pot of the cooking device has not reached the preset pressure threshold (for example, the countdown of the cooking device has 1 minute remaining and the pressure in the pot of the cooking device is still 10kPa), at this time, if the pressure in the pot is reduced according to the normal pressure reduction speed, then when the countdown reaches the predicted pressure reduction time, it cannot be ensured that the pressure in the pot of the cooking device is normally reduced to a safe pressure. At this time, the pressure reduction speed of the auxiliary pressure reduction unit can be adjusted so that when the countdown reaches the predicted pressure reduction time, the pressure in the pot of the cooking device reaches the preset pressure threshold, thereby ensuring the accuracy of the countdown display.

[0054] Optionally, in some embodiments of the present invention, the auxiliary depressurization unit includes at least one of an exhaust auxiliary depressurization unit, a water-cooled auxiliary depressurization unit, and an air-cooled auxiliary depressurization unit.

[0055] That is to say, in this embodiment of the present invention, the cooking equipment can be assisted by an exhaust auxiliary pressure reduction unit to reduce the pressure in the pot, the cooking equipment can be assisted by a water-cooled auxiliary pressure reduction unit to reduce the pressure in the pot, and the cooking equipment can be assisted by an air-cooled auxiliary pressure reduction unit to reduce the pressure in the pot.

[0056] Furthermore, in some embodiments of the present invention, the method further includes: acquiring the current ambient temperature of the cooking device, and correcting the predicted pressure drop time according to the current ambient temperature, and performing a countdown display according to the corrected predicted pressure drop time.

[0057] It can be understood that in this embodiment of the present invention, the predicted pressure drop time can also be corrected according to the current ambient temperature of the cooking equipment to obtain a more accurate predicted pressure drop time. Then, a countdown display is performed based on the corrected predicted pressure drop time to further improve the countdown accuracy. At the same time, there is no need to change the existing structure of the cooking equipment, and it has a wide range of applicability.

[0058] Furthermore, in some embodiments of the present invention, the method further includes: when the countdown reaches the predicted pressure reduction time and the pressure in the pot of the cooking device does not reach the preset pressure threshold, controlling the cooking device to issue a high pressure warning.

[0059] Specifically, in this embodiment of the present invention, when the countdown reaches the predicted pressure reduction time and the pressure in the pot of the cooking device has not reached the preset pressure threshold, at this time, since the pressure in the pot of the cooking device is still in a high-pressure state, a high-pressure warning can be issued by controlling the cooking device, thereby avoiding safety accidents caused by the user opening the cooking device without knowing it.

[0060] Optionally, in the above embodiment of the present invention, the high-voltage warning may include but is not limited to special displays such as time, characters, and graphics.

[0061] Furthermore, if Figure 3 As shown, in some embodiments of the present invention, after controlling the cooking device to end pressure reduction, the method further includes:

[0062] S301, obtaining the actual pressure reduction time of the cooking equipment.

[0063] It is understandable that, in this embodiment of the present invention, after the cooking device is controlled to finish reducing the pressure, the actual pressure reduction time of this pressure reduction can be obtained to update the pressure reduction time database.

[0064] S302: Establish a new mapping relationship between the actual pressure reduction time and the function selection instruction, the amount of food to be cooked, and the pressure in the pot, and update the new mapping relationship to the pressure reduction time database.

[0065] Specifically, in an embodiment of the present invention, after the cooking equipment is controlled to end the pressure reduction, a new mapping relationship can be established between the function selection instructions corresponding to this pressure reduction, the amount of cooked food and the pressure in the pot, combined with the actual pressure reduction time, and then the new mapping relationship is updated to the pressure reduction time database. Thus, by continuously updating the pressure reduction time database, the predicted pressure reduction time in the pressure reduction time database becomes more and more accurate.

[0066] The following is combined with Figure 4 In accordance with the specific embodiment of the present invention, the specific control process of the pressure reduction countdown display method of the cooking device in the embodiment of the present invention is described accordingly.

[0067] Specifically, if Figure 4 As shown, the cooking device executes step S1 after starting cooking.

[0068] S1, obtaining a function selection instruction of a cooking device.

[0069] S2, obtaining the amount of cooked food of the cooking device before the cooking stage is started.

[0070] S3, obtaining the pressure in the pot of the cooking device at the end of the cooking stage.

[0071] S4, obtaining a predicted pressure reduction time from a pressure reduction time database according to the function selection instruction, the amount of cooking food, and the pressure in the pot.

[0072] S5, countdown display according to the predicted blood pressure reduction time.

[0073] S6, when the pressure in the pot of the cooking device reaches a preset pressure threshold and the countdown reaches the predicted pressure reduction time, the cooking device is controlled to end the pressure reduction.

[0074] S7, obtaining the actual pressure reduction time of the cooking device, and establishing a new mapping relationship between the actual pressure reduction time and the function selection instruction, the amount of cooking food and the pressure in the pot, and updating the new mapping relationship to the pressure reduction time database.

[0075] In summary, according to an embodiment of the present invention, a method for displaying a pressure drop countdown for a cooking device obtains a function selection instruction for the cooking device, obtains the amount of food being cooked by the cooking device before the cooking phase begins, and obtains the pressure within the pot of the cooking device at the end of the cooking phase. Furthermore, based on the function selection instruction, the amount of food being cooked, and the pressure within the pot, a predicted pressure drop time is obtained from a pressure drop time database, wherein the pressure drop time database stores a mapping relationship between multiple sets of food amounts being cooked, pressure within the pot, and predicted pressure drop times. A countdown display is then performed based on the predicted pressure drop time. Thus, by obtaining a predicted pressure drop time from the pressure drop time database and displaying a countdown based on different function selection instructions, food amounts being cooked, and pressure within the pot, a countdown display of the pressure drop process of the cooking device is implemented, ensuring countdown accuracy without requiring changes to the existing structure of the cooking device, thus achieving wide applicability.

[0076] Based on the above-mentioned method for displaying a pressure reduction countdown for a cooking device in an embodiment of the present invention, an embodiment of the present invention further proposes a computer-readable storage medium on which a program for displaying a pressure reduction countdown for a cooking device is stored. When the program for displaying a pressure reduction countdown for a cooking device is executed by a processor, the method for displaying a pressure reduction countdown for a cooking device in the above-mentioned embodiment of the present invention is implemented.

[0077] It should be noted that the specific implementation of the computer-readable storage medium in the embodiment of the present invention can refer to the specific implementation of the pressure reduction countdown display method for the cooking device in the aforementioned embodiment of the present invention. To reduce redundancy, it will not be repeated here.

[0078] In summary, according to the computer-readable storage medium of an embodiment of the present invention, the processor executes the pressure reduction countdown display program of the cooking device stored thereon, and can obtain the predicted pressure reduction time from the pressure reduction time database and perform a countdown display according to different function selection instructions, cooking food quantity and pressure in the pot, thereby realizing the countdown display of the pressure reduction process of the cooking device and ensuring the accuracy of the countdown. At the same time, there is no need to change the existing structure of the cooking device, and it has a wide range of applicability.

[0079] Figure 5 4 is a block diagram of a voltage reduction countdown display device for a cooking device according to an embodiment of the present invention.

[0080] Specifically, if Figure 5 As shown, in some embodiments of the present invention, a voltage reduction countdown display device 100 for a cooking device includes: a first acquisition module 10 , a second acquisition module 20 , a third acquisition module 30 and a control module 40 .

[0082] Furthermore, in some embodiments of the present invention, the first acquisition module 10 is also used to obtain the time taken to heat the food to be cooked to a preset temperature threshold or a preset pressure threshold, and determine the amount of food cooked by the cooking device based on the time taken, or to heat the food to be cooked for a preset time to obtain the heating rate of the food to be cooked, and determine the amount of food cooked by the cooking device based on the heating rate.

[0083] Furthermore, in some embodiments of the present invention, the control module 30 is also used to determine whether the pressure in the pot of the cooking device reaches a preset pressure threshold when the countdown reaches a preset time threshold; if the pressure in the pot of the cooking device reaches the preset pressure threshold, then when the countdown reaches the predicted pressure reduction time, the cooking device is controlled to end the pressure reduction.

[0084] Furthermore, in some embodiments of the present invention, the cooking device includes an auxiliary pressure reducing unit, which is used to reduce the pressure in the pot of the cooking device. The control module 30 is also used to determine whether the pressure in the pot of the cooking device reaches a preset pressure threshold when the countdown reaches a preset time threshold; if the pressure in the pot of the cooking device does not reach the preset pressure threshold, the pressure reduction speed of the auxiliary pressure reducing unit is adjusted so that the pressure in the pot of the cooking device reaches the preset pressure threshold when the countdown reaches the predicted pressure reduction time.

[0085] Furthermore, in some embodiments of the present invention, the control module 30 is also used to control the cooking device to issue a high pressure warning when the countdown reaches the predicted pressure reduction time and the pressure in the pot of the cooking device does not reach a preset pressure threshold.

[0086] Furthermore, in some embodiments of the present invention, the auxiliary pressure-reducing unit includes at least one of an exhaust auxiliary pressure-reducing unit, a water-cooled auxiliary pressure-reducing unit, and an air-cooled auxiliary pressure-reducing unit.

[0087] Furthermore, in some embodiments of the present invention, the control module 30 is also used to obtain the current ambient temperature of the cooking device, correct the predicted pressure drop time according to the current ambient temperature, and display a countdown based on the corrected predicted pressure drop time.

[0088] Furthermore, in some embodiments of the present invention, the control module 30 is also used to obtain the actual pressure reduction time of the cooking equipment after controlling the cooking equipment to end the pressure reduction; establish a new mapping relationship between the actual pressure reduction time and the function selection instruction, the amount of cooked food and the pressure in the pot, and update the new mapping relationship to the pressure reduction time database.

[0089] It should be noted that the specific implementation of the pressure reduction countdown display device for cooking equipment in the embodiment of the present invention can be found in the aforementioned pressure reduction countdown display device for cooking equipment in the embodiment of the present invention, and will not be described again here to reduce redundancy.

[0090] In summary, according to an embodiment of the present invention, a pressure reduction countdown display device for a cooking device acquires a function selection instruction and the amount of food being cooked by the cooking device via a first acquisition module, acquires the amount of food being cooked by the cooking device before the cooking phase begins via a second acquisition module, and acquires the pressure within the pot of the cooking device at the end of the cooking phase via a third acquisition module. Then, based on the function selection instruction, the amount of food being cooked, and the pressure within the pot, a control module acquires a predicted pressure reduction time from a pressure reduction time database, and performs a countdown display based on the predicted pressure reduction time. The pressure reduction time database stores a mapping relationship between multiple sets of food amounts and pot pressures and predicted pressure reduction times. Thus, according to different function selection instructions, food amounts, and pot pressures, the predicted pressure reduction time is acquired from the pressure reduction time database and a countdown display is performed. This enables a countdown display of the pressure reduction process of the cooking device while ensuring countdown accuracy. This also eliminates the need to modify the existing structure of the cooking device, resulting in a wide range of applicability.
