Description

Technical Field

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

[0002] Current cooking products typically divide the cooking process into two stages: a preheating stage and a temperature / pressure maintenance stage. Because the weight of the food being cooked is uncertain, the preheating time is also uncertain. Current cooking products generally use a fuzzy timing scheme to display the cooking countdown; or they may not display a countdown during the preheating stage but display a precise countdown during the temperature / pressure maintenance stage; or they may display a fuzzy countdown during the preheating stage but a precise countdown during the temperature / pressure maintenance stage. All of these solutions result in an inaccurate overall cooking countdown display with significant errors, making it impossible for users to know the accurate cooking countdown time and thus affecting their cooking 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 countdown display method for a cooking device. This method obtains the remaining cooking time based on preset cooking parameters and preheating stage cooking parameters, and allows the target preset maintenance time to be a floating time. This eliminates errors caused by obtaining the remaining preheating stage time, thereby achieving accurate countdown display and improving the user's cooking experience.

[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 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, a first aspect of the present invention provides a countdown display method for a cooking device, wherein the method includes the following steps: obtaining preset cooking parameters of the cooking device and obtaining preheating stage cooking parameters of the cooking device; obtaining the remaining cooking time of the cooking device based on the preset cooking parameters and the preheating stage cooking parameters; and displaying a countdown based on the remaining cooking time, wherein the remaining cooking time is the sum of the remaining preheating stage time and the target preset maintenance time for controlling the cooking device to maintain at a preset target temperature and / or a preset target pressure.

[0008] According to the countdown display method for a cooking device proposed in this embodiment of the invention, preset cooking parameters of the cooking device and preheating stage cooking parameters of the cooking device are obtained. Based on the preset cooking parameters and preheating stage cooking parameters, the remaining cooking time of the cooking device is obtained, and a countdown is displayed based on the remaining cooking time. The remaining cooking time is the sum of the remaining preheating stage time and the target preset maintenance time for controlling the cooking device to maintain a preset target temperature and / or preset target pressure. Therefore, by obtaining the remaining cooking time based on the preset cooking parameters and preheating stage cooking parameters, the target preset maintenance time can be made to be a floating time, eliminating the error caused by obtaining the remaining preheating stage time, thereby achieving accurate countdown display and improving the user's cooking experience.

[0009] In addition, the countdown display method of the cooking device according to the above embodiments of the present invention may further include the following additional technical features:

[0010] According to one embodiment of the present invention, the preset cooking parameters include the preset target temperature and / or preset target pressure and the target preset holding time, and the preheating stage cooking parameters include the initial temperature and / or initial pressure of the food to be cooked, the first temperature at which the food to be cooked is cumulatively heated to a first preset time and the second temperature at which the food to be cooked is cumulatively heated to a second preset time, wherein the second preset time is greater than the first preset time.

[0011] According to one embodiment of the present invention, obtaining the remaining cooking time of the cooking device includes: obtaining a fitted temperature-time curve based on the initial temperature and / or initial pressure of the food to be cooked, the first preset time, the first temperature, the second preset time, and the second temperature; obtaining the preheating stage cooking time of the cooking device based on the preset target temperature and / or preset target pressure and the fitted temperature-time curve; and determining the remaining cooking time of the cooking device based on the preheating stage cooking time, the first preset time, the second preset time, and the target preset maintenance time.

[0012] According to an embodiment of the present invention, the fitted temperature-time curve is obtained by the following formula:

[0013]

[0014]

[0015] t1 = k(T - T0) + b,

[0016] Wherein, t1n is the second preset time, t1m is the first preset time, Tn is the second temperature, Tm is the first temperature, T0 is the initial temperature and / or initial pressure of the food to be cooked, t1 is the cooking time of the preheating stage, T is the preset target temperature and / or preset target pressure, k is the first curve fitting parameter, b is the second curve fitting parameter, and t1 = k(T-T0) + b is the fitted temperature-time curve.

[0017] According to one embodiment of the present invention, the method further includes: obtaining curve correction parameters; and performing time compensation on the cooking time of the preheating stage of the cooking equipment according to the curve correction parameters.

[0018] According to one embodiment of the present invention, the method further includes: obtaining the actual time consumed in the remaining preheating stage after the end of the remaining preheating stage; obtaining the actual maintenance time for controlling the cooking device to maintain at the preset target temperature and / or preset target pressure based on the actual time consumed in the remaining preheating stage and the remaining cooking time; and displaying a countdown based on the actual maintenance time.

[0019] According to one embodiment of the present invention, the method includes: obtaining the temperature and / or pressure of the food to be cooked; and determining that the remaining preheating stage ends after the temperature and / or pressure of the food to be cooked is greater than or equal to the preset target temperature and / or preset target pressure.

[0020] To achieve the above objectives, a second aspect of the present invention provides a computer-readable storage medium storing a countdown display program for a cooking device, wherein the countdown display program for the cooking device, when executed by a processor, implements the countdown display method for the cooking device described in the aforementioned embodiments of the present invention.

[0021] According to the computer-readable storage medium of the present invention, by executing the countdown display program of the cooking device through a processor, the remaining cooking time can be obtained according to the preset cooking parameters and the preheating stage cooking parameters. In this way, the target preset maintenance time can be made into a floating time to eliminate the error caused by obtaining the remaining preheating stage time, thereby achieving accurate countdown display and improving the user's cooking experience.

[0022] To achieve the above objectives, a third aspect of the present invention provides a countdown display device for a cooking device, wherein the device comprises: a first acquisition module, configured to acquire preset cooking parameters of the cooking device and acquire preheating stage cooking parameters of the cooking device; a second acquisition module, configured to acquire the remaining cooking time of the cooking device based on the preset cooking parameters and the preheating stage cooking parameters; and a control module, configured to perform a countdown display based on the remaining cooking time, wherein the remaining cooking time is the sum of the remaining preheating stage time and a target preset maintenance time for controlling the cooking device to maintain at a preset target temperature and / or a preset target pressure.

[0023] The countdown display device for a cooking apparatus according to an embodiment of the present invention acquires preset cooking parameters and preheating stage cooking parameters of the cooking apparatus through a first acquisition module, and acquires the remaining cooking time of the cooking apparatus based on the preset cooking parameters and preheating stage cooking parameters through a second acquisition module. Then, a control module displays the countdown based on the remaining cooking time. The remaining cooking time is the sum of the remaining preheating stage time and the target preset maintenance time for maintaining the cooking apparatus at a preset target temperature and / or preset target pressure. Therefore, by obtaining the remaining cooking time based on the preset cooking parameters and preheating stage cooking parameters, the target preset maintenance time can be made a floating time to eliminate errors caused by acquiring the remaining preheating stage time, thereby achieving accurate countdown display and improving the user's cooking experience.

[0024] To achieve the above objectives, a fourth aspect of the present invention provides a cooking apparatus, the cooking apparatus including the countdown display device of the cooking apparatus of the aforementioned embodiments of the present invention.

[0035] 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.

[0036] The following description, with reference to the accompanying drawings, describes a countdown display method for a cooking apparatus, a computer-readable storage medium, a countdown display device for a cooking apparatus, and a cooking apparatus according to embodiments of the present invention.

[0037] Figure 1 This is a flowchart illustrating a countdown display method for a cooking device according to an embodiment of the present invention.

[0038] Specifically, in some embodiments of the present invention, such as Figure 1 As shown, the countdown display method for cooking equipment includes the following steps:

[0039] S101, Obtain the preset cooking parameters of the cooking equipment, and obtain the cooking parameters of the preheating stage of the cooking equipment.

[0040] Specifically, in this embodiment, the preset cooking parameters include a preset target temperature and / or a preset target pressure and a target preset holding time. The preheating stage cooking parameters include the initial temperature and / or initial pressure of the food to be cooked, a first temperature reached after the food has been heated to a first preset time, and a second temperature reached after the food has been heated to a second preset time, wherein the second preset time is greater than the first preset time.

[0041] It should be noted that the initial temperature and / or initial pressure of the food being cooked can be obtained by installing a temperature sensor and / or a pressure sensor, and the first temperature and the second temperature can also be obtained by the temperature sensor. The preset target temperature and / or preset target pressure and the target preset holding time in the preset cooking parameters can be set by the user as needed.

[0042] S102: Obtain the remaining cooking time of the cooking equipment based on the preset cooking parameters and the cooking parameters of the preheating stage.

[0043] Specifically, in this embodiment, the remaining cooking time t0 of the cooking device can be obtained based on the preset target temperature and / or preset target pressure T and target preset holding time t2, the initial temperature and / or initial pressure T0 of the food to be cooked, the first temperature Tm of the food to be cooked after being heated to the first preset time, and the second temperature Tn of the food to be cooked after being heated to the second preset time.

[0044] S103, a countdown display is made based on the remaining cooking time, which is the sum of the remaining preheating stage time and the target preset maintenance time for controlling the cooking equipment to maintain at the preset target temperature and / or preset target pressure.

[0045] Specifically, in this embodiment, a countdown timer is displayed on the display device of the cooking equipment, showing the remaining cooking time t0. Figure 2 As shown, the remaining cooking time t0 is the sum of the remaining preheating stage time and the target preset maintenance time for controlling the cooking equipment to maintain at the preset target temperature and / or preset target pressure. Theoretically, the remaining cooking time t0 is equal to the sum of the theoretical time t1a of the remaining preset stage and the target preset maintenance time t2. In the actual cooking process, the remaining cooking time t0 is equal to the sum of the actual time t1s of the remaining preheating stage and the actual maintenance time t2s for controlling the cooking equipment to maintain at the preset target temperature and / or preset target pressure.

[0046] It should be noted that the theoretical time t1a for the remaining preset stage can be obtained based on the cooking time t1 of the preheating stage, the first preset time t1m, and the second preset time t1n, where the theoretical time t1a for the remaining preset stage is t1 - t1m - t1n.

[0047] Furthermore, in some embodiments of the present invention, such as Figure 3 As shown, the remaining cooking time of the cooking equipment is obtained, including:

[0048] S201, based on the initial temperature and / or initial pressure of the food to be cooked, the first preset time, the first temperature, the second preset time, and the second temperature, obtain the fitted temperature-time curve.

[0049] Specifically, in this embodiment, a fitted temperature-time curve can be obtained based on the initial temperature and / or initial pressure T0 of the food to be cooked, the first preset time t1m, the first temperature Tm, the second preset time t1n, and the second temperature Tn, using the following formula:

[0050]

[0051]

[0052] t1 = k(T - T0) + b,

[0053] Wherein, t1n is the second preset time, t1m is the first preset time, Tn is the second temperature, Tm is the first temperature, T0 is the initial temperature and / or initial pressure of the food to be cooked, t1 is the preset stage cooking time, T is the preset target temperature and / or preset target pressure, k is the first curve fitting parameter, b is the second curve fitting parameter, and t1=k(T-T0)+b is the fitted temperature-time curve.

[0054] S202, based on the preset target temperature and / or preset target pressure and the fitted temperature-time curve, obtain the cooking time of the preheating stage of the cooking equipment.

[0055] Specifically, in this embodiment, the preset target temperature and / or preset target pressure T are directly obtained after being set by the user. Based on the initial temperature and / or initial pressure T0 of the food to be cooked, the first preset time t1m, the first temperature Tm, the second preset time t1n, and the second temperature Tn, the fitted temperature-time curve t1 = k(T-T0) + b is obtained, where t1 is the preset stage cooking time, T0 is the initial temperature and / or initial pressure of the food to be cooked, k is the first curve fitting parameter, and b is the second curve fitting parameter. Substituting the preset target temperature and / or preset target pressure T set by the user into the fitted temperature-time curve t1 = k(T-T0) + b, the value of the preset stage cooking time t1 can be calculated.

[0056] S203, determine the remaining cooking time of the cooking equipment based on the preheating stage cooking time, the first preset time, the second preset time, and the target preset maintenance time.

[0057] Specifically, in this embodiment, the remaining cooking time t0 of the cooking device can be calculated using the following formula based on the preheating stage cooking time t1, the first preset time t1m, the second preset time t1n, and the target preset maintenance time t2:

[0058] t0 = t1 - t1m - t1n + t2,

[0059] It should be noted that after calculating the remaining cooking time t0 of the cooking equipment, a countdown display is made based on the remaining cooking time t0.

[0060] Furthermore, in some embodiments of the present invention, such as Figure 4 As shown, the countdown display method for cooking equipment also includes:

[0061] S301, obtain curve correction parameters.

[0062] Specifically, in this embodiment, a curve correction parameter c can be set, which is a compensation value added based on the fitted temperature-time curve.

[0063] S302, Time compensation is performed on the cooking time during the preheating stage of the cooking equipment based on the curve correction parameters.

[0064] Specifically, in this embodiment, after compensating the cooking time t1 of the preheating stage of the cooking equipment according to the curve correction parameter c, the compensated cooking time t1 of the preheating stage of the cooking equipment can be obtained according to the following formula:

[0065] t1 = k(T - T0) + b + c,

[0066] It should be noted that before time compensation is performed on the preheating stage cooking time of the cooking equipment according to the curve correction parameters, the preheating stage cooking time of the cooking equipment is t1 = k(T-T0) + b.

[0067] Furthermore, in some embodiments of the present invention, such as Figure 5 As shown, the countdown display method for cooking equipment also includes:

[0068] S401, Obtain the actual time consumed in the remaining preheating stage after the remaining preheating stage ends.

[0069] Specifically, in this embodiment, a timer device can be installed to obtain the actual time t1s of the remaining preheating stage after the end of the remaining preheating stage. In addition, the present invention does not specifically limit the method of obtaining the actual time t1s of the remaining preheating stage after the end of the remaining preheating stage.

[0070] S402, based on the actual time consumed in the remaining preheating stage and the remaining cooking time, obtain the actual duration for which the cooking equipment is maintained at the preset target temperature and / or preset target pressure.

[0071] Specifically, in this embodiment, the actual duration t2s of controlling the cooking device to maintain a preset target temperature and / or preset target pressure can be obtained according to the following formula:

[0072] t2s = t0 - t1s,

[0073] Where t0 is the remaining cooking time and t1s is the actual time spent in the remaining preheating stage.

[0074] S403 displays a countdown based on the actual duration of operation.

[0075] Specifically, in this embodiment, after calculating the actual holding time t2s, the countdown display time needs to be updated to the actual holding time t2s. This eliminates the error caused by obtaining the remaining preheating stage time, thereby achieving accurate countdown display and improving the user's cooking experience.

[0076] Furthermore, in some embodiments of the present invention, such as Figure 6 As shown, the countdown display methods for cooking equipment include:

[0077] S501, obtain the temperature and / or pressure of the food to be cooked.

[0078] Specifically, in this embodiment, the temperature and / or pressure of the food to be cooked can be obtained by setting a temperature sensor and / or a pressure sensor. Furthermore, the present invention does not specifically limit the method of obtaining the temperature and / or pressure of the food to be cooked.

[0079] S502, after the temperature and / or pressure of the food to be cooked are greater than or equal to the preset target temperature and / or preset target pressure, it is determined that the remaining preheating stage ends.

[0080] Specifically, in this embodiment, the remaining preheating stage is determined to end after the temperature and / or pressure of the food to be cooked, which are obtained in real time by a temperature sensor and / or a pressure sensor, are greater than or equal to the preset target temperature and / or preset target pressure set by the user.

[0081] In summary, such as Figure 2As shown, the cooking stage can be divided into a parameter setting stage, a preheating stage, and a preset target temperature and / or preset target pressure maintenance stage. The preheating stage can be further divided into a curve fitting stage and a residual preheating stage. The time of the curve fitting stage consists of a first preset time t1m and a second preset time t1n, wherein the second preset time t1n is greater than the first preset time t1m. Users can set preset cooking parameters in the parameter setting stage, and then enter the curve fitting stage. In this stage, a special display is performed on the display device of the cooking equipment. The special display can be time, characters, graphics, etc. In addition, the present invention does not specifically limit the specific form of the special display.

[0082] First, the parameter setting stage begins. Based on the function selected by the user on the cooking device, the target preset duration t2 and the preset target temperature and / or preset target pressure T are adjusted. The cooking device can have functions such as cooking rice, cooking porridge, and making soup. Different functions correspond to different target preset duration t2 and preset target temperature and / or preset target pressure T. After the user selects the cooking function, cooking can be started.

[0083] Then, the process enters the preheating stage. The initial temperature and / or initial pressure T0 of the food to be cooked is obtained through a temperature sensor. Heating continues for a first preset time t1m, and a first temperature Tm is obtained, where the first temperature Tm is the temperature at which the food to be cooked has been heated cumulatively to the first preset time t1m. Heating continues for a second preset time t1n, and a second temperature Tn is obtained, where the second temperature Tn is the temperature at which the food to be cooked has been heated cumulatively to the second preset time t1n. The first curve fitting parameter k and the second curve fitting parameter b are calculated according to the following formulas:

[0084]

[0085]

[0086] Then, based on the fitted temperature-time curve t1 = k(T-T0) + b and the curve correction parameter c, the preheating stage cooking time t1 = k(T-T0) + b + c is calculated. Substituting the preset target temperature and / or preset target pressure T into the formula t1 = k(T-T0) + b + c, the value of the preheating stage cooking time t1 can be obtained. Then, based on the preheating stage cooking time t1, the first preset time t1m, and the second preset time t1n, the theoretical time of the remaining preset stage t1a = t1 - t1m - t1n is calculated. Thus, based on the target preset maintenance time t2, the remaining cooking time of the cooking equipment t0 = t1a + t2 is calculated. At this time, the special display on the display device of the cooking equipment is updated to the remaining cooking time t0 of the cooking equipment, and the countdown is displayed with the remaining cooking time t0 of the cooking equipment.

[0087] The timer device obtains the actual time t1s of the remaining preheating stage after it ends. Based on the remaining cooking time t0 of the cooking equipment, the actual maintenance time t2s = t0-t1s of controlling the cooking equipment to maintain the preset target temperature and / or preset target pressure is calculated. At this time, the time on the display device of the cooking equipment is updated to the actual maintenance time t2s of controlling the cooking equipment to maintain the preset target temperature and / or preset target pressure. The countdown is displayed for the actual maintenance time t2s of controlling the cooking equipment to maintain the preset target temperature and / or preset target pressure until the cooking ends.

[0088] In summary, the countdown display method for a cooking device proposed in this embodiment of the invention obtains preset cooking parameters and preheating stage cooking parameters of the cooking device, and obtains the remaining cooking time of the cooking device based on the preset cooking parameters and preheating stage cooking parameters. The remaining cooking time is then displayed as a countdown, where the remaining cooking time is the sum of the remaining preheating stage time and the target preset maintenance time for maintaining the cooking device at a preset target temperature and / or preset target pressure. Therefore, by obtaining the remaining cooking time based on the preset cooking parameters and preheating stage cooking parameters, the target preset maintenance time can be made a floating time, eliminating errors caused by obtaining the remaining preheating stage time, thus achieving accurate countdown display and improving the user's cooking experience.

[0089] Based on the countdown display method for cooking equipment proposed in the foregoing embodiments of the present invention, the present invention also proposes a computer-readable storage medium storing a countdown display program for cooking equipment. When the countdown display program for cooking equipment is executed by a processor, it implements the countdown display method for cooking equipment as described in the embodiments of the present invention.

[0090] According to the computer-readable storage medium of the present invention, by executing the countdown display program of the cooking device through a processor, the remaining cooking time can be obtained according to the preset cooking parameters and the preheating stage cooking parameters. In this way, the target preset maintenance time can be made into a floating time to eliminate the error caused by obtaining the remaining preheating stage time, thereby achieving accurate countdown display and improving the user's cooking experience.

[0091] Figure 7 This is a block diagram of a countdown display device for a cooking apparatus according to an embodiment of the present invention.

[0092] Specifically, such as Figure 7 As shown, the countdown display device 100 of the cooking equipment includes a first acquisition module 10, a second acquisition module 20, and a control module 30.

[0093] The first acquisition module 10 is used to acquire the preset cooking parameters of the cooking equipment and the cooking parameters of the preheating stage of the cooking equipment; the second acquisition module 20 is used to acquire the remaining cooking time of the cooking equipment according to the preset cooking parameters and the cooking parameters of the preheating stage; the control module 30 is used to display a countdown based on the remaining cooking time, wherein the remaining cooking time is the sum of the remaining preheating stage time and the target preset maintenance time for controlling the cooking equipment to maintain at the preset target temperature and / or preset target pressure.

[0094] In some embodiments of the present invention, the preset cooking parameters include a preset target temperature and / or a preset target pressure and a target preset holding time. The cooking parameters in the preheating stage include the initial temperature and / or initial pressure of the food to be cooked, a first temperature at which the food to be cooked has been heated to a first preset time, and a second temperature at which the food to be cooked has been heated to a second preset time, wherein the second preset time is greater than the first preset time.

[0095] In some embodiments of the present invention, the second acquisition module 20 is specifically used to acquire a fitted temperature-time curve based on the initial temperature and / or initial pressure of the food to be cooked, a first preset time, a first temperature, a second preset time, and a second temperature; acquire the preheating stage cooking time of the cooking device based on the preset target temperature and / or preset target pressure and the fitted temperature-time curve; and determine the remaining cooking time of the cooking device based on the preheating stage cooking time, the first preset time, the second preset time, and the target preset maintenance time.

[0096] In some embodiments of the present invention, the first acquisition module 10 is specifically used to acquire the fitted temperature-time curve using the following formula:

[0097]

[0098]

[0099] t1 = k(T - T0) + b,

[0100] Wherein, t1n is the second preset time, t1m is the first preset time, Tn is the second temperature, Tm is the first temperature, T0 is the initial temperature and / or initial pressure of the food to be cooked, t1 is the preset stage cooking time, T is the preset target temperature and / or preset target pressure, k is the first curve fitting parameter, b is the second curve fitting parameter, and t1=k(T-T0)+b is the fitted temperature-time curve.

[0101] In some embodiments of the present invention, the first acquisition module 10 is further configured to acquire curve correction parameters and perform time compensation on the cooking time of the preheating stage of the cooking equipment according to the curve correction parameters.

[0102] In some embodiments of the present invention, the actual time consumed in the remaining preheating stage after the end of the remaining preheating stage is obtained; based on the actual time consumed in the remaining preheating stage and the remaining cooking time, the actual maintenance time for controlling the cooking device to maintain at the preset target temperature and / or preset target pressure is obtained; and a countdown display is performed based on the actual maintenance time.

[0103] In some embodiments of the present invention, the temperature and / or pressure of the food to be cooked are obtained; after the temperature and / or pressure of the food to be cooked is greater than or equal to a preset target temperature and / or a preset target pressure, it is determined that the remaining preheating stage ends.

[0104] It should be noted that other specific embodiments of the countdown display device for cooking equipment proposed in this embodiment of the invention can be found in the specific embodiments of the countdown display method for cooking equipment described above. To reduce redundancy, they will not be repeated here.

[0105] In summary, the countdown display device for a cooking device according to the embodiments of the present invention acquires preset cooking parameters and preheating stage cooking parameters of the cooking device through a first acquisition module, and acquires the remaining cooking time of the cooking device based on the preset cooking parameters and preheating stage cooking parameters through a second acquisition module. Then, a control module displays the countdown based on the remaining cooking time. The remaining cooking time is the sum of the remaining preheating stage time and the target preset maintenance time for maintaining the cooking device at a preset target temperature and / or preset target pressure. Therefore, by obtaining the remaining cooking time based on the preset cooking parameters and preheating stage cooking parameters, the target preset maintenance time can be made a floating time to eliminate errors caused by acquiring the remaining preheating stage time, thereby achieving accurate countdown display and improving the user's cooking experience.
