Description

Technical Field

[0001] This invention relates to the field of control technology for cooking equipment, and more particularly to a cooking device and its countdown display method and apparatus, and storage medium. 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, cooking parameters during the weighing and detection phase, and the heating parameters of the cooking device. Furthermore, it allows the target preset maintenance time to be a floating time, eliminating errors caused by obtaining the remaining preheating stage time, thereby achieving accurate countdown display and improving the user's cooking experience.

[0004] The second objective of this invention is to provide another method for displaying a countdown timer on a cooking device.

[0005] A third objective of this invention is to provide a computer-readable storage medium.

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

[0007] The fifth objective of this invention is to provide a countdown display device for another cooking appliance.

[0009] 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 cooking parameters of the weighing detection stage of the cooking device; obtaining the remaining cooking time of the cooking device based on the preset cooking parameters, the cooking parameters of the weighing detection stage, and the heating parameters of the cooking device; 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.

[0010] 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 cooking parameters during the weighing and detection phase of the cooking device are obtained. Based on the preset cooking parameters, the cooking parameters during the weighing and detection phase, and the heating parameters of the cooking device, the remaining cooking time of the cooking device is obtained. A countdown is then displayed based on the remaining cooking time, which is the sum of the remaining preheating phase time and the target preset maintenance time for maintaining the cooking device at a preset target temperature and / or a preset target pressure. Therefore, by obtaining the remaining cooking time based on the preset cooking parameters, the cooking parameters during the weighing and detection phase, and the heating parameters of the cooking device, the target preset maintenance time can be made a floating time to eliminate errors caused by obtaining the remaining preheating phase time, thereby achieving accurate countdown display and improving the user's cooking experience.

[0011] 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:

[0013] According to one embodiment of the present invention, obtaining the remaining cooking time of the cooking device includes: obtaining the mass of the food to be cooked based on the initial temperature and / or initial pressure of the food to be cooked, the first preset time, the first temperature, the average heating power, and the average thermal efficiency; obtaining the remaining preheating stage time based on the preset target temperature and / or preset target pressure, the first temperature, the average heating power, the average thermal efficiency, and the mass of the food to be cooked; and determining the remaining cooking time of the cooking device based on the remaining preheating stage time and the target preset maintenance time.

[0014] According to one embodiment of the present invention, the mass of the food to be cooked and the remaining preheating stage time are obtained by the following formula:

[0015]

[0016]

[0017] Wherein, m is the mass of the food to be cooked, p is the average heating power of the cooking equipment during the preheating stage, t is the first preset time, k is the average thermal efficiency of the cooking equipment during the preheating stage, c is the specific heat capacity, Tm is the first temperature, T0 is the initial temperature and / or initial pressure of the food to be cooked, T is the preset target temperature and / or preset target pressure, b is the preset time compensation parameter, and t1a is the remaining preheating stage time.

[0020] According to an 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.

[0021] To achieve the above objectives, a second aspect of the present invention provides another countdown display method for a cooking device. The method includes the following steps: acquiring preset cooking parameters of the cooking device, acquiring the initial temperature and / or initial pressure of the food to be cooked, and the first temperature at which the food to be cooked has been cumulatively heated to a first preset time; acquiring the remaining cooking time of the cooking device based on the preset cooking parameters, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature at which the food to be cooked has been cumulatively heated to the first preset time; 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 preset target pressure.

[0022] According to the countdown display method for a cooking device proposed in this embodiment of the invention, preset cooking parameters of the cooking device are obtained, along with the initial temperature and / or initial pressure of the food to be cooked, and the first temperature reached after the food has been heated to a first preset time. Then, based on the preset cooking parameters, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature reached after the food has been heated to the first preset time, the remaining cooking time of the cooking device is obtained. A countdown display is then performed based on the remaining cooking time, which 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, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature, 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.

[0023] 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:

[0024] 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.

[0025] According to one embodiment of the present invention, obtaining the remaining cooking time of the cooking device includes: obtaining the remaining preheating stage time based on the preset target temperature and / or preset target pressure, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature at which the food to be cooked has been heated to a first preset time; and determining the remaining cooking time of the cooking device based on the remaining preheating stage time and the target preset maintenance time.

[0026] According to one embodiment of the present invention, the remaining preheating stage time is obtained by the following formula:

[0027]

[0028] Wherein, t is the first preset time, Tm is the first temperature, T0 is the initial temperature and / or initial pressure of the food being cooked, T is the preset target temperature and / or preset target pressure, and t1a is the remaining preheating stage time.

[0029] 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.

[0030] According to one embodiment 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 the preset target temperature and / or preset target pressure, it is determined that the remaining preheating stage ends.

[0031] To achieve the above objectives, a third 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.

[0032] According to the computer-readable storage medium of the present invention, by executing a countdown display program of a cooking device through a processor, the remaining cooking time can be obtained based on preset cooking parameters, cooking parameters of the weighing detection stage, and heating parameters of the cooking device. 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.

[0033] To achieve the above objectives, a fourth 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 cooking parameters of the cooking device during the weighing detection stage; a second acquisition module, configured to acquire the remaining cooking time of the cooking device based on the preset cooking parameters, the cooking parameters of the weighing detection stage, and the heating parameters of the cooking device; and a first 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 the target preset maintenance time for controlling the cooking device to maintain at a preset target temperature and / or a preset target pressure.

[0034] The countdown display device for a cooking device according to an embodiment of the present invention acquires preset cooking parameters and weighing detection stage cooking parameters of the cooking device through a first acquisition module, and acquires the remaining cooking time of the cooking device through a second acquisition module based on the preset cooking parameters, weighing detection stage cooking parameters, and heating parameters of the cooking device. 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, weighing detection stage cooking parameters, and heating parameters of the cooking device, 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.

[0035] To achieve the above objectives, a fifth aspect of the present invention provides a countdown display device for a cooking apparatus, wherein the device comprises: a third acquisition module for acquiring preset cooking parameters of the cooking apparatus; a fourth acquisition module for acquiring the initial temperature and / or initial pressure of the food to be cooked, and a first temperature reached by the food to be cooked after a first preset time; a fifth acquisition module for acquiring the remaining cooking time of the cooking apparatus based on the preset cooking parameters, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature reached by the food to be cooked after a first preset time; and a second control module for 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 apparatus to maintain at a preset target temperature and / or preset target pressure.

Then, a fifth acquisition module acquires the remaining cooking time of the cooking apparatus based on the preset cooking parameters, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature reached by the food after being heated to the first preset time through a fifth acquisition module. A second control module then displays the countdown based on the remaining cooking time, which 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 acquiring the remaining cooking time based on the preset cooking parameters, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature, the target preset maintenance time can be made a floating time, eliminating errors caused by acquiring the remaining preheating stage time, thus achieving accurate countdown display and improving the user's cooking experience.

[0054] 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.

[0055] The following description, with reference to the accompanying drawings, describes the cooking apparatus and its countdown display method and device, as well as the storage medium, according to embodiments of the present invention.

[0056] Figure 1 This is a flowchart illustrating a countdown display method for a cooking device according to an embodiment of the present invention.

[0057] 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:

[0058] S101, Obtain the preset cooking parameters of the cooking equipment, and obtain the cooking parameters of the weighing detection stage of the cooking equipment.

[0059] Specifically, in this embodiment of the invention, the cooking stage of the cooking device can be divided into a preheating stage and a temperature / pressure holding stage. The preheating stage includes a weighing detection stage and a residual preheating stage. The weighing detection stage refers to the time period during which the mass of the food to be cooked is weighed. After the weighing detection stage ends, the residual preheating stage begins. The residual preheating stage refers to the time period during which the food to be cooked is preheated from the initial temperature / pressure to a preset target temperature and / or a preset target pressure. The temperature / pressure holding stage refers to the time period during which the cooking device maintains the food to be cooked at the preset target temperature and / or preset target pressure.

[0060] Optionally, in the above embodiments of the present invention, the preset cooking parameters of the cooking device include a preset target temperature and / or a preset target pressure and a target preset holding time. The cooking parameters of the weighing detection stage of the cooking device include the initial temperature and / or initial pressure of the food to be cooked, and the first temperature of the food to be cooked after being heated to a first preset time. In addition, the heating parameters of the cooking device are also acquired, such as the average heating power and average thermal efficiency of the cooking device in the preheating stage.

[0061] It should be noted that the preset target temperature and / or preset target pressure and the preset target duration in the preset cooking parameters are set by the user as needed. The initial temperature and / or initial pressure of the food to be cooked can be obtained by installing temperature sensors and / or pressure sensors, and the first temperature and the second temperature can also be obtained by temperature sensors. In addition, the average heating power of the cooking device in the preheating stage is the average of the heating power stored in the database for the last n times, and the average thermal efficiency of the cooking device in the preheating stage is the average of the thermal efficiency stored in the database for the last n times. Therefore, the average heating power and average thermal efficiency of the cooking device in the preheating stage can be directly obtained from the database. For example, the last n times can be 5 times, 10 times, 15 times, etc. The present invention does not specifically limit the value of the last n times.

[0062] S102: Based on the preset cooking parameters, the cooking parameters during the weighing and detection stage, and the heating parameters of the cooking equipment, obtain the remaining cooking time of the cooking equipment.

[0063] Specifically, in this embodiment, the remaining cooking time t0 of the cooking equipment can be obtained based on the preset target temperature and / or preset target pressure T, the 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, the average heating power P and average thermal efficiency k of the cooking equipment in the preheating stage.

[0064] 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.

[0065] 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.

[0066] 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:

[0067] S201, the quality of the food to be cooked is obtained based on the initial temperature and / or initial pressure of the food to be cooked, the first preset time, the first temperature, the average heating power, and the average thermal efficiency.

[0068] Specifically, in this embodiment, the mass m of the food to be cooked is obtained using the following formula, based on the initial temperature and / or initial pressure T0 of the food to be cooked, the first preset time t, the first temperature Tm, the average heating power p, and the average thermal efficiency k:

[0069]

[0070] Where m is the mass of the food to be cooked, p is the average heating power of the cooking equipment during the preheating stage, t is the first preset time, k is the average thermal efficiency of the cooking equipment during the preheating stage, c is the specific heat capacity, Tm is the first temperature, and T0 is the initial temperature and / or initial pressure of the food to be cooked.

[0071] S202, based on the preset target temperature and / or preset target pressure, first temperature, average heating power, average thermal efficiency and the quality of the food to be cooked, obtain the remaining preheating stage time.

[0072] Specifically, in this embodiment, the remaining preheating stage time t1a is obtained using the following formula, based on the preset target temperature and / or preset target pressure T, the first temperature Tm, the average heating power p, the average thermal efficiency k, and the mass m of the food to be cooked:

[0073]

[0074] Where m is the mass of the food to be cooked, p is the average heating power of the cooking equipment during the preheating stage, k is the average thermal efficiency of the cooking equipment during the preheating stage, c is the specific heat capacity, Tm is the first temperature, T is the preset target temperature and / or preset target pressure, b is the preset time compensation parameter, and t1a is the remaining preheating stage time.

[0075] It should be noted that the preset time compensation parameter b is a preset parameter, and its value depends on whether there is a heating stop time during the remaining preheating stage due to equipment safety issues such as overheating or temperature rise. If so, the remaining preheating stage time t1a is compensated by the preset time compensation parameter b. If not (i.e., b is 0), then, based on the above formula... and The formula can be obtained as follows: In other words, if there is no heating stop time in the remaining preheating stage, the remaining preheating stage time t1a can be directly calculated using the preset target temperature and / or preset target pressure T, the first temperature Tm, and the initial temperature and / or initial pressure T0 of the food being cooked.

[0076] S203, determine the remaining cooking time of the cooking equipment based on the remaining preheating stage time and the target preset maintenance time.

[0077] Specifically, in this embodiment, the remaining cooking time t0 of the cooking device is equal to the sum of the remaining preheating stage time t1a and the target preset maintenance time t2. The target preset maintenance time t2 is set at the factory or by the user.

[0078] Furthermore, in some embodiments of the present invention, such as Figure 4 As shown, the countdown display method for cooking equipment also includes:

[0079] S301, Obtain the actual time consumed in the remaining preheating stage after the end of the remaining preheating stage.

[0080] 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.

[0081] S302, 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.

[0082] Specifically, in this embodiment, the actual duration t2s of controlling the cooking device to maintain at the preset target temperature and / or preset target pressure is equal to the remaining cooking time t0 minus the actual duration t1s of the remaining preheating stage.

[0083] S303 displays a countdown based on the actual duration of operation.

[0084] 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.

[0085] Furthermore, in some embodiments of the present invention, such as Figure 5 As shown, the countdown display method for cooking equipment also includes:

[0086] S401, based on the actual time consumed in the remaining preheating stage, the preset target temperature and / or preset target pressure, the first temperature, the average heating power, and the mass of the food to be cooked, obtain the actual thermal efficiency of the cooking equipment.

[0087] Specifically, in this embodiment, the actual thermal efficiency ks of the cooking equipment is obtained by the following formula based on the actual time t1s of the remaining preheating stage, the preset target temperature and / or preset target pressure T, the first temperature Tm, the average heating power p, and the mass m of the food to be cooked:

[0088]

[0089] Where ks is the actual thermal efficiency, m is the mass of the food being cooked, c is the specific heat capacity, T is the preset target temperature and / or preset target pressure, Tm is the first temperature, p is the average heating power of the cooking equipment during the preheating stage, t1s is the actual time consumed during the remaining preheating stage, and b is the preheating time compensation parameter.

[0090] S402 updates the average thermal efficiency of the cooking equipment based on the actual thermal efficiency.

[0091] Specifically, after calculating the actual thermal efficiency ks, the actual thermal efficiency ks is uploaded to the database, and then the average thermal efficiency of the cooking equipment in the preheating stage is calculated from the database by obtaining the thermal efficiency ks stored in the last n times. The last n times can be 5 times, 10 times, 15 times, etc. The present invention does not specifically limit the value of the last n times.

[0092] Furthermore, in some embodiments of the present invention, such as Figure 6 As shown, the countdown display methods for cooking equipment include:

[0093] S501, obtain the temperature and / or pressure of the food to be cooked.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] In summary, such as Figure 2 As 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 divided into a detection stage and a remaining preheating stage. The first preset time t can be set by the user. During the detection 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.

[0098] 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.

[0099] Then, the preheating stage begins. The initial temperature and / or initial pressure T0 of the food to be cooked is obtained. After the food is heated to a first preset time t, a first temperature Tm is obtained. The average thermal efficiency k from the database (based on the average of the last n stored values) is then obtained, yielding the average thermal efficiency of the cooking equipment. Based on the specific heat capacity c and the average heating power p, the mass m of the food to be cooked can then be obtained using the following formula:

[0100]

[0101] After obtaining the mass m of the food to be cooked, the remaining preheating stage time t1a can be obtained using the following formula, based on the preset time compensation parameter b, specific heat capacity c, preset target temperature and / or preset target pressure T, first temperature Tm, average heating power p, average thermal efficiency k, and the mass m of the food to be cooked:

[0102]

[0103] Therefore, the sum of the calculated remaining preheating stage time t1a and the target preset maintenance time t2 can be used as the remaining cooking time t0 of the cooking equipment, and the special display on the display device of the cooking equipment is updated to the remaining cooking time t0, so as to display the countdown with the remaining cooking time t0.

[0104] At this point, the actual time t1s of the remaining preheating stage is timed using a timer device. Then, based on the specific heat capacity c, the preheating time compensation parameter b, the actual time t1s of the remaining preheating stage, the preset target temperature and / or preset target pressure T, the first temperature Tm, the average heating power p, and the mass m of the food to be cooked, the actual thermal efficiency ks of the cooking equipment is obtained using the following formula:

[0105]

[0106] After calculating the actual thermal efficiency ks of the cooking equipment, store the actual thermal efficiency ks of the cooking equipment in the database.

[0107] During the preset target temperature and / or preset target pressure maintenance phase, the remaining cooking time t0 minus the actual remaining preheating time t1s is used as the actual maintenance time t2s for controlling the cooking equipment to maintain the preset target temperature and / or preset target pressure. This actual maintenance time t2s is displayed on the cooking equipment's display device, and a countdown is performed based on this actual maintenance time t2s until cooking is complete. This allows the target preset maintenance time to be a floating time, eliminating errors caused by obtaining the remaining preheating time, thus achieving accurate countdown display and improving the user's cooking experience.

[0108] In summary, the countdown display method for a cooking device proposed in this embodiment of the invention obtains preset cooking parameters of the cooking device, obtains cooking parameters during the weighing and detection phase of the cooking device, and obtains the remaining cooking time of the cooking device based on the preset cooking parameters, the cooking parameters during the weighing and detection phase, and the heating parameters of the cooking device. The remaining cooking time is then displayed as a countdown, where the remaining cooking time is the sum of the remaining preheating phase time and the target preset maintenance time for maintaining the cooking device at a preset target temperature and / or a preset target pressure. Therefore, by obtaining the remaining cooking time based on the preset cooking parameters, the cooking parameters during the weighing and detection phase, and the heating parameters of the cooking device, the target preset maintenance time can be made a floating time, eliminating the error caused by obtaining the remaining preheating phase time, thus achieving accurate countdown display and improving the user's cooking experience.

[0109] Based on the countdown display method for cooking equipment proposed in the aforementioned embodiments of the present invention, this embodiment also proposes another countdown display method for cooking equipment. It should be noted that the preset time compensation parameter b is used as a preset parameter, and its value depends on whether there is a heating stop time during the remaining preheating stage due to equipment safety issues such as overheating or temperature rise. If not (i.e., b is 0), then... Figure 7 As shown, the countdown display method for cooking equipment involves the following steps:

[0110] S601, obtain the preset cooking parameters of the cooking device, and obtain the initial temperature and / or initial pressure of the food to be cooked, and the first temperature of the food to be cooked after being heated to the first preset time.

[0111] Specifically, in this embodiment, the cooking stage of the cooking device can be divided into a preheating stage and a temperature / pressure holding stage. The preheating stage includes a residual preheating stage, which refers to the time period during which the food to be cooked is preheated from the initial temperature / pressure to the preset target temperature and / or preset target pressure. The temperature / pressure holding stage refers to the time period during which the cooking device maintains the food to be cooked at the preset target temperature and / or preset target pressure.

[0112] The preset cooking parameters include a preset target temperature and / or a preset target pressure and a target preset holding time. The preset target temperature and / or preset target pressure and target preset holding time are set by the user as needed. The preset target temperature and / or preset target pressure and target preset holding time can be directly obtained. The initial temperature and / or initial pressure of the food to be cooked, as well as the first temperature of the food to be cooked after being heated to the first preset time, can be obtained by installing a temperature sensor and / or pressure sensor.

[0113] S602, based on preset cooking parameters, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature at which the food to be cooked has been heated to a first preset time, the remaining cooking time of the cooking device is obtained.

[0114] 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, the initial temperature and / or initial pressure T0 of the food to be cooked, and the first temperature Tm of the food to be cooked after being heated to the first preset time t.

[0115] S603 displays a countdown 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 the preset target temperature and / or preset target pressure.

[0116] Specifically, in this embodiment, a countdown timer is displayed on the display device of the cooking equipment, showing the remaining cooking time t0. Figure 8 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 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 the preset target temperature and / or preset target pressure.

[0117] Furthermore, in some embodiments of the present invention, such as Figure 9 As shown, the remaining cooking time of the cooking equipment is obtained, including:

[0118] S701, based on the preset target temperature and / or preset target pressure, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature at which the food to be cooked has been heated to the first preset time, obtain the remaining preheating stage time.

[0119] Specifically, in this embodiment, the remaining preheating stage time is obtained based on the preset target temperature and / or preset target pressure T, the initial temperature and / or initial pressure T0 of the food to be cooked, and the first temperature Tm of the food to be cooked after being heated to the first preset time t, and the following formula:

[0120]

[0121] Where t is the first preset time, Tm is the first temperature, T0 is the initial temperature and / or initial pressure of the food being cooked, T is the preset target temperature and / or preset target pressure, and t1a is the remaining preheating stage time.

[0122] S702 determines the remaining cooking time of the cooking equipment based on the remaining preheating stage time and the target preset maintenance time.

[0123] Specifically, in this embodiment, the remaining cooking time t0 of the cooking device is equal to the sum of the remaining preheating stage time t1a and the target preset maintenance time t2. The target preset maintenance time t2 is set at the factory or by the user.

[0124] Furthermore, in some embodiments of the present invention, such as Figure 10 As shown, the countdown display method for cooking equipment also includes:

[0125] S801, obtain the actual time consumed in the remaining preheating stage after the end of the remaining preheating stage.

[0126] 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.

[0127] S802, based on the actual time consumed in the remaining preheating stage and the remaining cooking time, obtains the actual duration for which the cooking equipment is maintained at the preset target temperature and / or preset target pressure.

[0128] Specifically, in this embodiment, the actual duration t2s of controlling the cooking device to maintain at the preset target temperature and / or preset target pressure is equal to the remaining cooking time t0 minus the actual duration t1s of the remaining preheating stage.

[0129] S803 displays a countdown based on the actual duration of operation.

[0130] 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.

[0131] Furthermore, in some embodiments of the present invention, such as Figure 11 As shown, the countdown display methods for cooking equipment include:

[0132] S901, obtain the temperature and / or pressure of the food to be cooked.

[0133] 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.

[0134] S902, 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.

[0135] 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.

[0136] In summary, such as Figure 8 As 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 includes a remaining preheating stage, and the first preset time t can be set by the user.

[0137] 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.

[0138] Then, the preheating stage begins, where the preset target temperature and / or preset target pressure T, the initial temperature and / or initial pressure T0 of the food to be cooked, and the first temperature Tm of the food to be cooked after being heated to a first preset time t are obtained. The remaining preheating stage time is then calculated using the following formula:

[0139]

[0140] Therefore, the sum of the calculated remaining preheating stage time t1a and the target preset maintenance time t2 can be used as the remaining cooking time t0 of the cooking equipment, and the special display on the display device of the cooking equipment is updated to the remaining cooking time t0, so as to display the countdown with the remaining cooking time t0.

[0141] During the preset target temperature and / or preset target pressure maintenance phase, the remaining cooking time t0 minus the actual remaining preheating time t1s is used as the actual maintenance time t2s for controlling the cooking equipment to maintain the preset target temperature and / or preset target pressure. This actual maintenance time t2s is displayed on the cooking equipment's display device, and a countdown is performed based on this actual maintenance time t2s until cooking is complete. This allows the target preset maintenance time to be a floating time, eliminating errors caused by obtaining the remaining preheating time, thus achieving accurate countdown display and improving the user's cooking experience.

[0142] In summary, the countdown display method for a cooking device proposed in this embodiment of the invention obtains preset cooking parameters of the cooking device, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature reached after the food has been heated to a first preset time. Then, based on the preset cooking parameters, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature reached after the food has been heated to the first preset time, the remaining cooking time of the cooking device is obtained. A countdown display is then performed based on the remaining cooking time, which 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, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature, the target preset maintenance time can be made 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.

[0143] 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.

[0144] According to the computer-readable storage medium of the present invention, by executing a countdown display program of a cooking device through a processor, the remaining cooking time can be obtained based on preset cooking parameters, cooking parameters of the weighing detection stage, and heating parameters of the cooking device. 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.

[0145] Figure 12 This is a block diagram of a countdown display device for a cooking apparatus according to an embodiment of the present invention.

[0146] Specifically, such as Figure 12 As shown, the countdown display device 100 of the cooking equipment includes a first acquisition module 10, a second acquisition module 20, and a first control module 30.

[0147] The first acquisition module 10 is used to acquire the preset cooking parameters of the cooking equipment and the cooking parameters of the weighing detection stage of the cooking equipment; the second acquisition module 20 is used to acquire the remaining cooking time of the cooking equipment based on the preset cooking parameters, the cooking parameters of the weighing detection stage and the heating parameters of the cooking equipment; the first 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.

[0148] 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 weighing detection stage include the initial temperature and / or initial pressure of the food to be cooked, and the first temperature at which the food to be cooked has been heated to a first preset time; and the heating parameters of the cooking equipment include the average heating power and average thermal efficiency of the cooking equipment in the preheating stage.

[0149] In some embodiments of the present invention, the second acquisition module 20 is specifically used to acquire the mass of the food to be cooked based on the initial temperature and / or initial pressure, a first preset time, a first temperature, average heating power, and average thermal efficiency of the food to be cooked; acquire the remaining preheating stage time based on the preset target temperature and / or preset target pressure, the first temperature, average heating power, average thermal efficiency, and the mass of the food to be cooked; and determine the remaining cooking time of the cooking equipment based on the remaining preheating stage time and the target preset maintenance time.

[0150] In some embodiments of the present invention, the second acquisition module 20 is specifically used to acquire the mass of the food to be cooked and the remaining preheating stage time using the following formula:

[0151]

[0152]

[0153] Where m is the mass of the food to be cooked, p is the average heating power of the cooking equipment during the preheating stage, t is the first preset time, k is the average thermal efficiency of the cooking equipment during the preheating stage, c is the specific heat capacity, Tm is the first temperature, T0 is the initial temperature and / or initial pressure of the food to be cooked, T is the preset target temperature and / or preset target pressure, b is the preset time compensation parameter, and t1a is the remaining preheating stage time.

[0154] 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.

[0155] In some embodiments of the present invention, the actual thermal efficiency of the cooking equipment is obtained based on the actual time consumed in the remaining preheating stage, the preset target temperature and / or the preset target pressure, the first temperature, the average heating power, and the mass of the food to be cooked; and the average thermal efficiency of the cooking equipment is updated based on the actual thermal efficiency.

[0156] 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.

[0157] 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.

[0158] In summary, the countdown display device for a cooking device according to the embodiments of the present invention acquires preset cooking parameters and weighing detection stage cooking parameters of the cooking device through a first acquisition module, and acquires the remaining cooking time of the cooking device through a second acquisition module based on the preset cooking parameters, weighing detection stage cooking parameters, and heating parameters of the cooking device. Then, a control module displays the countdown based on the remaining cooking time, 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, weighing detection stage cooking parameters, and heating parameters of the cooking device, 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.

[0159] Figure 13 This is a block diagram of a countdown display device for a cooking apparatus according to another embodiment of the present invention.

[0160] Specifically, such as Figure 13 As shown, the countdown display device 100 of the cooking equipment includes a third acquisition module 40, a fourth acquisition module 50, a fifth acquisition module 60, and a second control module 70.

[0161] The third acquisition module 40 is used to acquire the preset cooking parameters of the cooking equipment; the fourth acquisition module 50 is used to acquire the initial temperature and / or initial pressure of the food to be cooked, and the first temperature at which the food to be cooked has been heated to the first preset time; the fifth acquisition module 60 is used to acquire the remaining cooking time of the cooking equipment based on the preset cooking parameters, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature at which the food to be cooked has been heated to the first preset time; the second control module 70 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.

[0162] 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.

[0163] In some embodiments of the present invention, the fifth acquisition module 60 is specifically used to acquire the remaining preheating stage time based on the preset target temperature and / or preset target pressure, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature at which the food to be cooked has been heated to the first preset time; and to determine the remaining cooking time of the cooking device based on the remaining preheating stage time and the target preset maintenance time.

[0164] In some embodiments of the present invention, the remaining preheating stage time is obtained using the following formula:

[0165]

[0166] Where t is the first preset time, Tm is the first temperature, T0 is the initial temperature and / or initial pressure of the food being cooked, T is the preset target temperature and / or preset target pressure, and t1a is the remaining preheating stage time.

[0167] 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.

[0168] 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.

[0169] 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.

[0170] In summary, the countdown display device for a cooking apparatus according to the embodiments of the present invention acquires preset cooking parameters of the cooking apparatus through a third acquisition module, and acquires the initial temperature and / or initial pressure of the food to be cooked, and the first temperature at which the food to be cooked has been accumulated to a first preset time through a fourth acquisition module. Then, a fifth acquisition module acquires the remaining cooking time of the cooking apparatus based on the preset cooking parameters, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature at which the food to be cooked has been accumulated to the first preset time through a fifth acquisition module. The second control module then displays the countdown based on the remaining cooking time, which is the sum of the remaining preheating stage time and the target preset maintenance time for maintaining the cooking apparatus at the preset target temperature and / or preset target pressure. Therefore, by acquiring the remaining cooking time based on the preset cooking parameters, the initial temperature and / or initial pressure of the food to be cooked, and the first temperature, the target preset maintenance time can be made a floating time, eliminating the error caused by acquiring the remaining preheating stage time, thereby achieving accurate countdown display and improving the user's cooking experience.
