[0001] This invention relates to the field of cooking equipment technology, and in particular to a method for displaying a countdown timer for a cooking device, a computer-readable storage medium, a countdown timer display device for a cooking device, and a cooking device. Background Technology

[0002] Currently, pressure cooker products using this technology typically have a pressure-reducing stage after high-pressure cooking to prevent users from being scalded by high-pressure steam when opening the lid. However, the problem with this technology is that some products only display a special symbol during the pressure-reducing process, while others only display the heat-keeping time. This makes it impossible for users to know whether the pressure-reducing process has completely ended, making it difficult for them to open the lid easily and significantly reducing the user experience. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the first objective of this invention is to provide a method for displaying a pressure reduction countdown in a cooking device. This method can accurately obtain the remaining pressure reduction time by fitting a pressure reduction curve to the cooking device, thereby improving the accuracy of the pressure reduction countdown. Furthermore, it does not require changes to the existing structure of the cooking device and has wide applicability.

[0004] A second objective of this invention is to provide a computer-readable storage medium.

[0005] The third objective of this invention is to provide a pressure reduction countdown display device for a cooking appliance.

[0006] The fourth objective of this invention is to provide a cooking device.

[0007] To achieve the above objectives, the first aspect of the present invention provides a method for displaying a countdown timer for a cooking device, comprising: acquiring a first pot pressure with a cumulative pressure reduction of a first preset time and a second pot pressure with a cumulative pressure reduction of a second preset time, wherein the second preset time is greater than or equal to the first preset time, and the second pot pressure is less than or equal to the first pot pressure; acquiring a fitted pressure reduction curve based on the pot pressure when the cooking device finishes cooking, the first preset time, the first pot pressure, the second preset time, and the second pot pressure; acquiring a predicted pressure reduction time based on a preset pressure threshold and the fitted pressure reduction curve, and acquiring the remaining pressure reduction time based on the second preset time and the predicted pressure reduction time; and displaying a countdown based on the remaining pressure reduction time.

[0008] According to an embodiment of the present invention, a pressure reduction countdown display method for a cooking device involves acquiring the first pot pressure after a cumulative pressure reduction of a first preset time and the second pot pressure after a cumulative pressure reduction of a second preset time, wherein the second preset time is greater than or equal to the first preset time, and the second pot pressure is less than or equal to the first pot pressure. Then, a fitted pressure reduction curve is obtained based on the pot pressure at the end of cooking, the first preset time, the first pot pressure, the second preset time, and the second pot pressure. Next, a predicted pressure reduction time is obtained based on a preset pressure threshold and the fitted pressure reduction curve. The remaining pressure reduction time is then obtained based on the second preset time and the predicted pressure reduction time. Finally, a countdown is displayed based on the remaining pressure reduction time. Therefore, the remaining pressure reduction time is accurately obtained through the fitted pressure reduction curve of the cooking device, thereby improving the accuracy of the pressure reduction countdown without altering the existing structure of the cooking device, making it widely applicable.

[0009] In addition, the pressure reduction countdown display method for the cooking device according to embodiments of the present invention may also have the following additional technical features:

[0010] According to an embodiment of the present invention, the fitted blood pressure reduction curve is obtained by the following formula: c = p0; P = at 2 +bt+c; where p1 is the pressure inside the first pot, t1 is the first preset time, p2 is the pressure inside the second pot, t2 is the second preset time, p0 is the pressure inside the pot when the cooking device finishes cooking, and P = at 2 +bt+c corresponds to the fitted pressure reduction curve, P is the target pressure threshold, and t is the predicted pressure reduction time.

[0011] According to an embodiment of the present invention, the step of obtaining the predicted pressure reduction time based on a preset pressure threshold and the fitted pressure reduction curve, and obtaining the remaining pressure reduction time based on the second preset time and the predicted pressure reduction time, includes: determining the preset pressure threshold as the target pressure threshold; obtaining the predicted pressure reduction time based on the target pressure threshold and the fitted pressure reduction curve; and determining the difference between the second preset time and the predicted pressure reduction time as the remaining pressure reduction time.

[0012] According to an embodiment of the present invention, the method further includes: when the countdown has a remaining preset time threshold, determining whether the pressure inside the pot when the cooking device ends cooking reaches a preset pressure threshold; if the pressure inside the pot when the cooking device ends cooking reaches the preset pressure threshold, then controlling the cooking device to end the pressure reduction when the countdown reaches the predicted pressure reduction time.

[0013] According to one embodiment of the present invention, the cooking device includes an auxiliary pressure reducing unit for reducing the pressure inside the pot of the cooking device. The method further includes: when the countdown has a remaining preset time threshold, determining whether the pressure inside the pot when the cooking device finishes cooking has reached a preset pressure threshold; if the pressure inside the pot when the cooking device finishes cooking has not reached the preset pressure threshold, adjusting the pressure reducing speed of the auxiliary pressure reducing unit so that when the countdown reaches the predicted pressure reducing time, the pressure inside the pot of the cooking device reaches the preset pressure threshold.

[0014] According to one embodiment of the present invention, the method further includes: when the countdown reaches the predicted pressure drop time and the pressure inside the pot of the cooking device does not reach the preset pressure threshold, controlling the cooking device to issue a high-pressure warning.

[0015] According to one embodiment of the present invention, the auxiliary pressure reduction unit includes at least one of an exhaust auxiliary pressure reduction unit, a water-cooled auxiliary pressure reduction unit, and an air-cooled auxiliary pressure reduction unit.

[0016] To achieve the above objectives, a computer-readable storage medium is provided in a second aspect embodiment of the present invention, which stores a voltage reduction countdown display program for a cooking device. When the voltage reduction countdown display program for the cooking device is executed by a processor, it implements the voltage reduction countdown display method for the cooking device described in the embodiments of the present invention.

[0017] According to embodiments of the present invention, when a computer-readable storage medium is used to execute a countdown display program for a cooking device stored thereon via a processor actuator, the remaining pressure reduction time can be accurately obtained through the fitted pressure reduction curve of the cooking device, thereby improving the accuracy of the pressure reduction countdown without changing the existing structure of the cooking device, and thus having wide applicability.

[0018] To achieve the above objectives, a pressure reduction countdown display device for a cooking apparatus according to a third aspect embodiment of the present invention includes: a first acquisition module, configured to acquire a first pot pressure with a cumulative pressure reduction of a first preset time and a second pot pressure with a cumulative pressure reduction of a second preset time, wherein the second preset time is greater than or equal to the first preset time, and the second pot pressure is less than or equal to the first pot pressure; a second acquisition module, configured to acquire a fitted pressure reduction curve based on the pot pressure when the cooking apparatus finishes cooking, the first preset time, the first pot pressure, the second preset time, and the second pot pressure; a third acquisition module, configured to acquire a predicted pressure reduction time based on a preset pressure threshold and the fitted pressure reduction curve, and acquire the remaining pressure reduction time based on the second preset time and the predicted pressure reduction time; and a control module, configured to perform a countdown display based on the remaining pressure reduction time.

[0019] According to an embodiment of the present invention, a pressure reduction countdown display device for a cooking apparatus acquires, via a first acquisition module, the first pot pressure accumulated over a first preset time and the second pot pressure accumulated over a second preset time, wherein the second preset time is greater than or equal to the first preset time, and the second pot pressure is less than or equal to the first pot pressure. Then, via a second acquisition module, a fitted pressure reduction curve is acquired based on the pot pressure at the end of cooking, the first preset time, the first pot pressure, the second preset time, and the second pot pressure. Next, via a third acquisition module, a predicted pressure reduction time is acquired based on a preset pressure threshold and the fitted pressure reduction curve, and the remaining pressure reduction time is acquired based on the second preset time and the predicted pressure reduction time. Finally, via a control module, a countdown is displayed based on the remaining pressure reduction time. Thus, the remaining pressure reduction time is accurately obtained using the fitted pressure reduction curve of the cooking apparatus, thereby improving the accuracy of the pressure reduction countdown without altering the existing structure of the cooking apparatus, making it widely applicable.

[0028] Figure 6 This is a block diagram of a cooking apparatus according to an embodiment of the present invention. Detailed Implementation

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

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

[0031] Figure 1 This is a flowchart illustrating the pressure reduction countdown display method of a cooking device according to an embodiment of the present invention.

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

[0033] S101, acquire the first pot pressure after a cumulative pressure reduction of a first preset time and the second pot pressure after a cumulative pressure reduction of a second preset time, wherein the second preset time is greater than or equal to the first preset time and the second pot pressure is less than or equal to the first pot pressure.

[0034] It is understood that, in this embodiment of the present invention, after the cooking device finishes cooking, the cooking device can be controlled to accumulate a first preset time of pressure reduction, and the first pressure inside the pot can be obtained through a sensor (temperature sensor or pressure sensor). The cooking device can also be controlled to continue accumulating a second preset time of pressure reduction, and the second pressure inside the pot can be obtained through a sensor (temperature sensor or pressure sensor). The pressure inside the pot of the cooking device decreases as the pressure reduction time accumulates.

[0035] S102, obtain the fitted pressure reduction curve based on the pressure inside the pot when the cooking device finishes cooking, the first preset time, the first pressure inside the pot, the second preset time, and the second pressure inside the pot.

[0036] It is understood that, in this embodiment of the present invention, the actual pressure reduction data of the cooking device (first preset time, first pot pressure, second preset time and second pot pressure) can be used in combination with the pot pressure when the cooking device finishes cooking to fit the pressure reduction curve of the cooking device in order to obtain the fitted pressure reduction curve.

[0037] Furthermore, in some embodiments of the present invention, the fitted blood pressure reduction curve is obtained using the following formula:

[0038]

[0039]

[0040] c = p0;…………(3)

[0041] P = at 2 +bt+c;…………(4)

[0042] Where p1 is the pressure inside the first pot, t1 is the first preset time, p2 is the pressure inside the second pot, t2 is the second preset time, p0 is the pressure inside the pot when the cooking device finishes cooking, and P = at 2 +bt+c corresponds to the fitted pressure reduction curve, where P is the target pressure threshold and t is the predicted pressure reduction time.

[0043] S103, obtain the predicted pressure reduction time based on the preset pressure threshold and the fitted pressure reduction curve, and obtain the remaining pressure reduction time based on the second preset time and the predicted pressure reduction time.

[0044] It is understood that, in this embodiment of the present invention, the next pressure reduction time of the cooking device can be predicted based on a preset pressure threshold and a fitted pressure reduction curve to obtain the predicted pressure reduction time. Then, the remaining pressure reduction time can be obtained by combining the second preset time of cumulative pressure reduction of the cooking device.

[0045] S104 displays a countdown based on the remaining pressure reduction time.

[0046] Specifically, in this embodiment of the invention, the remaining pressure reduction time can be accurately obtained by fitting the pressure reduction curve of the cooking device, and a countdown display can be made based on the remaining pressure reduction time, thereby improving the accuracy of the pressure reduction countdown, without changing the existing structure of the cooking device, and thus having wide applicability.

[0047] Furthermore, such as Figure 2 As shown, in some embodiments of the present invention, the predicted pressure reduction time is obtained based on a preset pressure threshold and a fitted pressure reduction curve, and the remaining pressure reduction time is obtained based on a second preset time and the predicted pressure reduction time, including:

[0048] S201, the preset pressure threshold is set as the target pressure threshold.

[0049] It is understood that in this embodiment of the present invention, the user can input a preset pressure threshold through the control panel of the cooking device to determine the preset pressure threshold as the target pressure threshold. During the depressurization process, the cooking device needs to reduce the pressure inside the pot at the end of cooking to the target pressure threshold.

[0050] S202, based on the target pressure threshold and the fitted pressure reduction curve, obtain the predicted pressure reduction time.

[0051] It is understood that in this embodiment of the present invention, the predicted pressure reduction time can be obtained by substituting the target pressure threshold into the formula (4) corresponding to the aforementioned fitted pressure reduction curve. It should be noted that the predicted pressure reduction time refers to the total time required for the pressure inside the pot to decrease to the target pressure threshold when the cooking device finishes cooking.

[0052] For example, in the above embodiments of the present invention, assuming that the preset pressure threshold set by the user is 0, then substituting P=0 into the aforementioned formula (4) yields the following formula:

[0053]

[0054] Where t3 is the predicted pressure drop time.

[0055] It should be noted that formula (5) has two solutions, positive and negative. The positive value is taken as the total time required for the pressure inside the pot to drop to the target pressure threshold when the cooking equipment finishes cooking, which is the predicted pressure drop time.

[0056] S203, the difference between the second preset time and the predicted pressure reduction time is determined as the remaining pressure reduction time.

[0057] It is understood that, in this embodiment of the present invention, since the predicted pressure reduction time is the total time required for the pressure inside the pot to decrease to the target pressure threshold when the cooking device finishes cooking, it is necessary to subtract the second preset time that has been accumulated for pressure reduction, and thus determine the difference between the second preset time and the predicted pressure reduction time as the remaining pressure reduction time.

[0058] Furthermore, such as Figure 3 As shown, in some embodiments of the present invention, the method further includes:

[0059] S301, when the countdown has a remaining preset time threshold, determine whether the pressure inside the pot when the cooking device finishes cooking has reached a preset pressure threshold.

[0060] It should be understood that, in this embodiment of the present invention, when the countdown has a remaining preset time threshold, it can be determined whether the pressure inside the pot of the cooking device has reached a preset pressure threshold, thereby ensuring the accuracy of the countdown display for the pressure reduction process.

[0061] S302, if the pressure inside the pot reaches a preset pressure threshold when the cooking device finishes cooking, the cooking device will stop depressurizing when the countdown reaches the predicted pressure reduction time.

[0062] Specifically, in this embodiment of the present invention, when the pressure inside the pot of the cooking device reaches a preset pressure threshold, it can be determined 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.

[0063] It should be noted that in the above embodiments of the present invention, there may be, but not limited to, the following two situations: (i) the pressure inside 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 stop pressure reduction; (ii) the pressure inside 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 stop pressure reduction.

[0064] Furthermore, in some embodiments of the present invention, the cooking device includes an auxiliary pressure reducing unit, which is used to reduce the pressure inside the pot of the cooking device. The method further includes: when the countdown has a remaining preset time threshold, determining whether the pressure inside the pot when the cooking device finishes cooking has reached a preset pressure threshold; if the pressure inside the pot when the cooking device finishes cooking has not reached the preset pressure threshold, adjusting the pressure reducing speed of the auxiliary pressure reducing unit so that when the countdown reaches the predicted pressure reducing time, the pressure inside the pot of the cooking device reaches the preset pressure threshold.

[0065] Specifically, in this embodiment of the present invention, when the countdown has a remaining preset time threshold and the pressure inside 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 inside the pot of the cooking device is still 10 kPa), if the pressure inside the pot is reduced at the normal pressure reduction rate, then when the countdown reaches the predicted pressure reduction time, it cannot be guaranteed that the pressure inside the pot of the cooking device will normally decrease to the preset pressure threshold. At this time, the pressure reduction rate of the auxiliary pressure reduction unit can be adjusted so that when the countdown reaches the predicted pressure reduction time, the pressure inside the pot of the cooking device reaches the preset pressure threshold, thereby ensuring the accuracy of the countdown display.

[0066] Furthermore, in some embodiments of the present invention, the method further includes: when the countdown reaches the predicted pressure reduction time and the pressure inside the pot of the cooking device has not reached the preset pressure threshold, controlling the cooking device to issue a high-pressure warning.

[0067] Specifically, in this embodiment of the present invention, when the countdown reaches the predicted pressure reduction time and the pressure inside the pot of the cooking device has not reached the preset pressure threshold, since the pressure inside the pot of the cooking device is still in a high-pressure state, the cooking device can be controlled to issue a high-pressure warning, thereby preventing the user from opening the cooking device without knowing it and causing a safety accident.

[0068] Optionally, in the above embodiments of the present invention, the high-voltage warning may include, but is not limited to, special displays such as time, characters, and graphics.

[0069] Furthermore, in some embodiments of the present invention, the auxiliary pressure reduction unit includes at least one of an exhaust auxiliary pressure reduction unit, a water-cooled auxiliary pressure reduction unit, and an air-cooled auxiliary pressure reduction unit.

[0070] In other words, in this embodiment of the present invention, the pressure inside the pot can be reduced by an exhaust-assisted pressure reduction unit, a water-cooled auxiliary pressure reduction unit, or an air-cooled auxiliary pressure reduction unit.

[0071] The following is in conjunction with the appendix Figure 4 The specific control process of the pressure reduction countdown display method of the cooking device according to the specific embodiments of the present invention will be described accordingly.

[0072] Specifically, such as Figure 4 As shown, after the cooking equipment finishes cooking, step S1 is executed.

[0073] S1, obtain the pressure inside the pot when the cooking equipment finishes cooking.

[0074] S2, accumulate pressure reduction for the first preset time, and obtain the first pressure inside the pot of the cooking equipment.

[0075] S3, accumulate the second preset time for pressure reduction, and obtain the second pressure inside the pot of the cooking device.

[0076] S4. Based on the pressure inside the pot when the cooking equipment finishes cooking, the first preset time, the first pressure inside the pot, the second preset time, and the second pressure inside the pot, obtain the fitted pressure reduction curve.

[0077] S5, obtain the predicted pressure reduction time based on the preset pressure threshold and the fitted pressure reduction curve.

[0078] S6, obtain the remaining pressure reduction time based on the second preset time and the predicted pressure reduction time.

[0079] S7 displays a countdown based on the remaining pressure reduction time.

[0080] S8, when the pressure inside the pot of the cooking device drops to the preset pressure threshold and the remaining pressure reduction time countdown ends, control the cooking device to end the pressure reduction process.

[0081] Based on the voltage reduction countdown display method for cooking equipment in the above embodiments of the present invention, the present invention also proposes a computer-readable storage medium storing a voltage reduction countdown display program for cooking equipment. When the voltage reduction countdown display program for cooking equipment is executed by a processor, it implements the voltage reduction countdown display method for cooking equipment in the above embodiments of the present invention.

[0082] It should be noted that the specific implementation of the computer-readable storage medium in the embodiments of the present invention can be found in the specific implementation of the pressure reduction countdown display method of the cooking device in the foregoing embodiments of the present invention. To reduce redundancy, it will not be repeated here.

[0083] In summary, the pressure reduction countdown display method for a cooking device according to an embodiment of the present invention acquires the first pot pressure after a cumulative pressure reduction of a first preset time and the second pot pressure after a cumulative pressure reduction of a second preset time, wherein the second preset time is greater than or equal to the first preset time, and the second pot pressure is less than or equal to the first pot pressure. Then, a fitted pressure reduction curve is obtained based on the pot pressure at the end of cooking, the first preset time, the first pot pressure, the second preset time, and the second pot pressure. Next, a predicted pressure reduction time is obtained based on a preset pressure threshold and the fitted pressure reduction curve, and the remaining pressure reduction time is obtained based on the second preset time and the predicted pressure reduction time. Finally, a countdown is displayed based on the remaining pressure reduction time. Therefore, the remaining pressure reduction time is accurately obtained through the fitted pressure reduction curve of the cooking device, thereby improving the accuracy of the pressure reduction countdown, without requiring changes to the existing structure of the cooking device, and thus has wide applicability.

[0084] Figure 5 This is a block diagram of a pressure reduction countdown display device for a cooking apparatus according to an embodiment of the present invention.

[0085] Specifically, such as Figure 5 As shown, in some embodiments of the present invention, the pressure reduction countdown display device 100 of the cooking equipment includes: a first acquisition module 10, a second acquisition module 20, a third acquisition module 30, and a control module 40.

[0086] The first acquisition module 10 is used to acquire the first pot pressure after a cumulative pressure reduction of a first preset time and the second pot pressure after a cumulative pressure reduction of a second preset time, wherein the second preset time is greater than or equal to the first preset time, and the second pot pressure is less than or equal to the first pot pressure; the second acquisition module 20 is used to acquire a fitted pressure reduction curve based on the pot pressure when the cooking device finishes cooking, the first preset time, the first pot pressure, the second preset time, and the second pot pressure; the third acquisition module 30 is used to acquire the predicted pressure reduction time based on the preset pressure threshold and the fitted pressure reduction curve, and to acquire the remaining pressure reduction time based on the second preset time and the predicted pressure reduction time; the control module 40 is used to display a countdown based on the remaining pressure reduction time.

[0087] Furthermore, in some embodiments of the present invention, the fitted blood pressure reduction curve is obtained using the following formula: c = p0; P = at 2 +bt+c; where p1 is the pressure inside the first pot, t1 is the first preset time, p2 is the pressure inside the second pot, t2 is the second preset time, p0 is the pressure inside the pot when the cooking device finishes cooking, and P = at 2 +bt+c corresponds to the fitted pressure reduction curve, where P is the target pressure threshold and t is the predicted pressure reduction time.

[0088] Furthermore, in some embodiments of the present invention, the third acquisition module 30 is further configured to: determine the preset pressure threshold as the target pressure threshold; obtain the predicted pressure reduction time based on the target pressure threshold and the fitted pressure reduction curve; and determine the difference between the second preset time and the predicted pressure reduction time as the remaining pressure reduction time.

[0089] Furthermore, in some embodiments of the present invention, the control module 40 is also used to determine whether the pressure inside the pot when the cooking device finishes cooking reaches a preset pressure threshold when the countdown has a remaining preset time threshold; if the pressure inside the pot when the cooking device finishes cooking reaches the preset pressure threshold, then when the countdown reaches the predicted pressure reduction time, the control module 40 controls the cooking device to stop reducing pressure.

[0090] Furthermore, in some embodiments of the present invention, the cooking device includes an auxiliary pressure reducing unit, which is used to reduce the pressure inside the pot of the cooking device. The control module 40 is also used to determine whether the pressure inside the pot when the cooking device finishes cooking reaches a preset pressure threshold when the countdown has a remaining preset time threshold. If the pressure inside the pot when the cooking device finishes cooking does not reach the preset pressure threshold, the pressure reducing speed of the auxiliary pressure reducing unit is adjusted so that the pressure inside the pot of the cooking device reaches the preset pressure threshold when the countdown reaches the predicted pressure reducing time.

[0091] Furthermore, in some embodiments of the present invention, the control module 40 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 inside the pot of the cooking device has not reached the preset pressure threshold.

[0092] Furthermore, in some embodiments of the present invention, the auxiliary pressure reduction unit includes at least one of an exhaust auxiliary pressure reduction unit, a water-cooled auxiliary pressure reduction unit, and an air-cooled auxiliary pressure reduction unit.

[0093] It should be noted that the specific implementation of the pressure reduction countdown display device of the cooking equipment in the embodiments of the present invention can be found in the aforementioned pressure reduction countdown display device of the cooking equipment in the embodiments of the present invention. To reduce redundancy, it will not be described again here.

[0094] In summary, the pressure reduction countdown display device for a cooking appliance according to an embodiment of the present invention acquires, via a first acquisition module, the first pot pressure accumulated over a first preset time and the second pot pressure accumulated over a second preset time, wherein the second preset time is greater than or equal to the first preset time, and the second pot pressure is less than or equal to the first pot pressure. Then, via a second acquisition module, a fitted pressure reduction curve is acquired based on the pot pressure at the end of cooking, the first preset time, the first pot pressure, the second preset time, and the second pot pressure. Next, via a third acquisition module, a predicted pressure reduction time is acquired based on a preset pressure threshold and the fitted pressure reduction curve, and the remaining pressure reduction time is acquired based on the second preset time and the predicted pressure reduction time. Finally, via a control module, a countdown is displayed based on the remaining pressure reduction time. Therefore, the remaining pressure reduction time is accurately obtained through the fitted pressure reduction curve of the cooking appliance, thereby improving the accuracy of the pressure reduction countdown without altering the existing structure of the cooking appliance, making it widely applicable.

To reduce redundancy, it will not be described again here.

[0098] In summary, the cooking apparatus according to the embodiments of the present invention, employing the aforementioned pressure reduction countdown display device, can accurately obtain the remaining pressure reduction time through the fitted pressure reduction curve of the cooking apparatus, thereby improving the accuracy of the pressure reduction countdown, and without changing the existing structure of the cooking apparatus, thus having wide applicability.
