It should be understood that the objects so used may be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described.

[0053] See Figure 1 , which shows a flowchart of the juice-receiving control method of the cooking appliance according to the embodiment of the present application.

[0054] As Figure 1 shown, according to the first aspect of the embodiment of the present application, a juice-receiving control method of a cooking appliance is provided, and the method includes but is not limited to being implemented by the following steps S1 to step S2:

[0055] Step S1. In response to the signal that the cooking appliance performs pressure-holding cooking until the first preset time, control the cooking appliance to perform a first juice-receiving at the first pressure and the first exhaust frequency;

[0056] It should be noted that based on the traditional cooking mode of the cooking appliance, after placing the ingredients and filling with water, the upper cover of the cooking appliance is closed, and the cooking appliance is started to enter the heating and pressure - increasing cooking stage. In the heating and pressure - increasing cooking stage, the heating module at the bottom of the cooking appliance starts to operate, heating the cavity to raise the temperature and pressure inside the cavity. When it is detected that the heating and pressure - increasing inside the cavity is completed, it is adjusted to the pressure - maintaining cooking stage.

[0057] It can be understood that during the heating and pressure - increasing process of the cooking appliance, from the start of the cooking appliance to when the pressure inside the cavity reaches the preset pressure (for example, 70 kPa), the exhaust device of the cooking appliance is in a working state in the early stage, used to discharge the cold air inside the cavity. After the cold air is discharged, the exhaust device stops working. Among them, the exhaust device can be an exhaust valve. After the exhaust valve stops working, the exhaust valve presses the cavity of the cooking appliance in the way of a weight, making the cavity of the cooking appliance in a sealed state.

[0058] In some embodiments, the upper cover of the cooking appliance is provided with a temperature - control probe. The temperature - control probe is used to detect the temperature inside the cavity. There is a preset corresponding relationship between the temperature inside the cavity and the pressure inside the cavity. Therefore, when the temperature - control probe detects the temperature point corresponding to the preset pressure, a signal that the cooking appliance has increased the pressure to the preset pressure is obtained.

[0059] In some embodiments, there is a preset corresponding relationship between the pressure inside the cavity of the cooking appliance and the downward displacement position of the inner - pot cavity. The displacement of the inner - pot cavity is detected by a displacement sensor. When the displacement sensor detects the displacement point corresponding to the preset pressure, a signal that the cooking appliance has increased the pressure to the preset pressure is obtained.

[0060] It can be understood that after the cooking appliance increases the pressure to 70 kPa and jumps to the pressure - maintaining cooking stage, if the first preset time has passed in the pressure - maintaining cooking stage, the cooking appliance is controlled to enter the first juice - reducing stage.

[0061] In some embodiments, the first preset time in the pressure - maintaining cooking stage is shorter than the pressure - maintaining cooking time of traditional cooking appliances. For example, the pressure - maintaining cooking time of traditional cooking appliances is 15 minutes, and the pressure - maintaining cooking time of the cooking appliance in the embodiment of the present application can be 7 minutes; the pressure - maintaining cooking time of traditional cooking appliances is 10 minutes, and the pressure - maintaining cooking time of the cooking appliance in the embodiment of the present application can be 5 minutes, etc. By shortening the first preset time, the overall cooking time of the cooking appliance can be shortened.

[0062] In step S1, in response to a signal that the cooking appliance has maintained pressure and cooked for a first preset time, the cooking appliance is controlled to collect juice once at a first pressure and a first exhaust frequency, that is, when the cooking appliance is operated at the first pressure, the cooking appliance discharges the gas in the cavity intermittently at the first exhaust frequency through the exhaust device. For example, the exhaust valve is controlled to be opened intermittently at the first exhaust frequency, so that the gas generated after the liquid in the cavity boils is discharged from the cooking appliance.

[0063] It can be understood that since the exhaust valve is opened intermittently, the first pressure may change when the exhaust valve is opened and closed. Therefore, the first pressure is not necessarily a constant value. It can be set and adjusted in real time according to actual needs. For example, when the required pressure is greater than the current pressure in the cavity, the heating power can be increased. When the required pressure is lower than the current pressure in the cavity, the heating power can be reduced. This is not limited here.

[0064] In some embodiments of step S1, based on the above scheme, before responding to the signal that the cooking appliance maintains pressure and cooks for a first preset time and controlling the cooking appliance to collect juice once at a first pressure and a first exhaust frequency, the method further includes:

[0065] (1) determining the amount of liquid in the cooking utensil when the cooking utensil is pressurized;

[0066] It should be noted that the cooking appliance pressure-starting refers to the state in which the cooking appliance is pressurized to a preset pressure after being started. The amount of liquid in the cooking appliance is determined under the pressure-starting condition, and the amount of liquid in the cavity can be confirmed before entering the juice collection process, providing data support for the subsequent determination of the first exhaust frequency. The amount of liquid in the cooking cavity determined in advance is used to regulate the exhaust process of juice collection, so as to make the variable pressure juice collection more efficient, reduce the juice collection cooking time and achieve faster and better cooking results.

[0067] (2) adjusting the first exhaust frequency according to the amount of liquid, wherein the first exhaust frequency is negatively correlated with the amount of liquid.

[0068] It should be noted that the negative correlation between the first exhaust frequency and the liquid amount means that: the larger the liquid amount, the smaller the first exhaust frequency; and the smaller the liquid amount, the larger the first exhaust frequency.

[0069] In some embodiments of the present application, based on the above solution, determining the amount of liquid in the cooking utensil includes:

[0070] Determining the heating duration according to the heating start time and the pressure start time of the cooking appliance;

[0071] The amount of liquid in the cooking vessel is determined according to the heating time.

[0072] It should be noted that the heating duration is the duration between the heating start time and the pressure rising time. Since the liquid volume in the cooking cavity is closely related to the pressure rising rate in the pot, the cooking appliance can determine the liquid volume in the cooking appliance before the first sauce reduction based on the heating duration, so as to realize the adaptive adjustment of the second sauce reduction, take into account the differences in different cooking processes and different ingredients conditions in the pot, and regulate the sauce reduction process in real time, so as to obtain a faster and better cooking effect, and avoid problems such as slow sauce reduction, poor flavoring effect, and uneven coloring caused by the user's incorrect operation or excessive water addition.

[0073] In addition, the first exhaust frequency can also be determined according to the ingredient properties. For example, for ingredients with a relatively long cooking duration corresponding to their ingredient properties, the first exhaust frequency can be appropriately reduced to keep the first pressure in the cavity and accelerate the softening of the ingredients, etc.

[0074] For example: the first exhaust frequency can be exhausting for 4 seconds every 10 seconds, every, exhausting for 3 seconds every 8 seconds, etc. Specifically, it can be set according to influencing factors such as ingredient properties and the added liquid volume, and no limitation is made here.

[0075] In some embodiments, the first pressure is greater than or equal to 70 kPa, that is, the cooking appliance is in a high-pressure cooking state during the first sauce reduction process, so as to enhance the sauce reduction effect of the ingredients without reducing the cooking efficiency of the cooking appliance, and promote the flavoring and fragrance enhancement of the ingredients.

[0076] It should be noted that the heating and pressure rising of the cooking appliance are realized by heating with the bottom heating module. Therefore, if the cooking appliance is to operate at the first pressure, the bottom heating module needs to provide the corresponding heating power. In the embodiments of the present application, the average heating power during the first sauce reduction process can be controlled to be about 1500 W, so as not to reduce the cooking efficiency of the ingredients.

[0077] It can be understood that controlling the cooking appliance to exhaust intermittently enables the cooking appliance to store energy and boost pressure during heating in the cavity when the exhaust valve is closed, and enables the liquid in the cavity to boil and reduce the sauce when the exhaust valve is opened. For example: if the exhaust valve operates at an exhaust frequency of exhausting for the last 4 seconds every 10 seconds, then the first 4 seconds of every 10 seconds are in the energy storage and pressure boosting state, and the last 4 seconds are in the exhaust state, enabling the liquid in the cavity to boil and reduce the sauce.

[0078] For example: The bottom heating module operates at an average heating power of 1500W. When the exhaust valve is closed, the energy stored in the cavity causes the pressure in the cavity to reach the first pressure. When the exhaust valve is opened, there is a pressure difference between the pressure in the cooking cavity and the ambient pressure. For example, the pressure in the cavity is 70 kPa and the ambient pressure is 1000 Pa. The large pressure difference causes the liquid in the cavity to boil. Since the ingredients become soft after pressure-holding cooking, during this stage, thickening the sauce can make the juice more easily enter the ingredients, ensuring the flavor and aroma of the ingredients are enhanced without reducing the cooking efficiency and shortening the cooking time.

[0079] In some embodiments of step S1, based on the foregoing solution, controlling the cooking appliance to perform a first thickening process according to the first pressure and the first exhaust frequency includes:

[0080] Step S11. Determine the first heating power according to the first pressure;

[0081] It should be noted that the heating and pressure increase of the cooking appliance are realized by heating with the bottom heating module. Therefore, if the cooking appliance is to operate at the first pressure, the bottom heating module needs to provide the corresponding first heating power. In the embodiments of the present application, the average heating power during the first thickening process can be controlled to be about 1500W, so as not to reduce the cooking efficiency of the ingredients. It can be understood that since the first pressure is not necessarily a fixed value, the corresponding first heating power is not necessarily a fixed value either. For example, when the required power is greater than the cavity pressure, the first heating power can be increased; when the required power is less than the cavity pressure, the first heating power can be decreased.

[0082] Step S12. Determine the first exhaust duration within each first exhaust cycle according to the first exhaust frequency and the first preset ratio;

[0083] The first preset ratio refers to the ratio of the first exhaust duration corresponding to each first exhaust cycle to the first exhaust cycle. For example: The first exhaust cycle is 10 seconds, and the first preset ratio is 2 / 5, then the first exhaust duration is 4 seconds.

[0084] It can be understood that for different types of ingredients, different weights of ingredients, or different liquid amounts, different first exhaust frequencies and first preset ratios can be set, or the same first exhaust frequency and different first preset ratios can be set, so that the control of the first thickening process can better meet the cooking requirements and further improve the cooking efficiency. For example: When cooking 1 kg of braised pork and adding 200 g of water, if the first exhaust frequency is set to 1 / 10, the first exhaust cycle is 10 seconds, the first preset ratio is set to 2 / 5, and the first exhaust duration is 4 seconds; if 150 g of water is added, the first exhaust frequency is set to 1 / 8, the first exhaust cycle is 8 seconds, the first preset ratio is set to 1 / 2, and the first exhaust duration is 4 seconds.

[0085] Step S13. Control the cooking appliance to operate at the first heating power and with the first exhaust duration within each first exhaust period, so that the liquid in the cavity boils to achieve primary sauce reduction.

[0086] For example: The first heating power is 1500 W, each first exhaust period is 10 seconds, each first exhaust duration is 4 seconds, and it is preset to exhaust in the last 4 seconds of every 10 seconds. Then, assuming the continuous process of primary sauce reduction is 1 minute, there are 6 first exhaust periods. Control the exhaust valve to close in the first 6 seconds of each first exhaust period and control the exhaust valve to open in the last 4 seconds of each first exhaust period.

[0087] In some embodiments of step S1, based on the foregoing solution, a temperature control module is provided at the bottom of the cooking appliance. Before responding to the first exit signal for primary sauce reduction, the method further includes:

[0088] Obtain the bottom temperature detected by the temperature control module;

[0089] Among them, the signal that the bottom temperature reaches the first temperature threshold is used to represent the first exit signal for primary sauce reduction.

[0090] The first exit signal refers to the signal indicating the end of the primary sauce reduction stage.

[0091] It should be noted that in the early stage of cooking ingredients, since the density of oil is lower than that of water, oil and water will be stratified, that is, the oil floats on the upper layer of water; during the primary sauce reduction process, the liquid boils through intermittent exhaust, so that the oil and water roll and mix, and part of the water evaporates during the exhaust process, so that the proportion of oil in the soup increases, and then the bottom temperature gradually increases. Therefore, by detecting the bottom temperature, the current sauce reduction state can be determined. For example, when the first temperature threshold is exceeded, dry burning may occur at the bottom or in some areas, resulting in too high a temperature; therefore, by using the signal that the bottom temperature reaches the first temperature threshold as the exit signal for primary sauce reduction, over-sauce reduction and abnormal temperature increase can be avoided. Among them, the range of the first temperature threshold can be 120°C to 125°C.

[0092] Step S2. In response to the first exit signal for primary sauce reduction, control the cooking appliance to perform secondary sauce reduction at the second pressure until the second exit signal for secondary sauce reduction is obtained, and the second pressure is less than the first pressure.

[0093] For example: In the primary sauce reduction stage, when the bottom temperature reaches 120°C, the primary sauce reduction is exited, and the cooking appliance is controlled to perform secondary sauce reduction at the second pressure.

[0094] The second exit signal refers to the signal indicating the end of the secondary sauce reduction stage.

[0095] It can be understood that since the liquid in the cavity may not be completely reduced in the first reduction stage, and the ingredients in the cavity may further release water during the pressure cooking in the first reduction stage, therefore, through the second reduction, the liquid in the cavity boils evenly, and the soup is emulsified again and evenly distributed on the ingredients, playing a role in further flavoring and enhancing the aroma of the ingredients.

[0096] It can be understood that even if the amount of liquid added in the early stage of cooking is different, or the properties of the ingredients are different (such as different water release amounts), after the first reduction, the liquid amount in the cavity can be basically within a relatively small range. Therefore, in the second reduction stage,

[0097] In some embodiments of step S2, based on the foregoing solution, controlling the cooking appliance to perform the second reduction according to the second pressure includes:

[0098] Step S21A. Determine the second heating power according to the second pressure;

[0099] It should be noted that the heating and pressure increase of the cooking appliance are achieved by heating with the bottom heating module. Therefore, if the cooking appliance is to operate according to the second pressure, the bottom heating module needs to provide the corresponding second heating power. In the embodiments of the present application, the average heating power during the second reduction can be controlled to be about 1800W, so as not to reduce the cooking efficiency of the ingredients. It can be understood that since the second pressure is not necessarily a fixed value, the corresponding second heating power is not necessarily a fixed value either. For example, when the required power is greater than the cavity pressure, the second heating power can be increased; when the required power is less than the cavity pressure, the second heating power can be decreased.

[0100] In some embodiments, the second pressure is less than or equal to 10 kPa.

[0101] Step S22A. Determine the respective second exhaust durations within each second exhaust cycle according to the second exhaust frequency and the second preset ratio;

[0102] The second preset ratio refers to the ratio between the second exhaust duration corresponding to each second exhaust cycle and the second exhaust cycle. For example: if the second exhaust cycle is 10 seconds and the first preset ratio is 3 / 5, then the first exhaust duration is 6 seconds.

[0103] It can be understood that even if the amount of liquid added in the early stage of cooking is different, or the properties of the ingredients are different (such as different water release amounts), after the first reduction, the liquid amount in the cavity can be basically within a relatively small range. Therefore, in the second reduction stage, in order to further shorten the cooking time, the second exhaust frequency can be set to be greater than the first exhaust frequency, and the second preset ratio can be greater than the first preset ratio.

[0104] Step S23A. Control the cooking appliance to operate at the second heating power and for the second exhaust duration within each second exhaust period, so that the liquid in the cavity boils to achieve secondary thickening of the sauce.

[0105] For example: the second heating power is 1800 W, each second exhaust period is 10 seconds, each second exhaust duration is 8 seconds, and it is preset to exhaust in the last 8 seconds of every 10 seconds. Then, assuming the continuous process of secondary thickening of the sauce is 1 minute, there are 6 second exhaust periods in total. Control the exhaust valve to close in the first 2 seconds of each second exhaust period, and control the exhaust valve to open in the last 8 seconds of each second exhaust period.

[0106] In some embodiments, the cooking appliance is provided with an exhaust valve. After controlling the cooking appliance to operate at the second pressure and for the second exhaust duration within each second exhaust period, so that the liquid in the cavity boils to achieve secondary thickening of the sauce, the method further includes:

[0107] Control the exhaust valve to remain open so that the cooking appliance completes pressure relief.

[0108] It can be understood that since the liquid volume in the cavity is very small after the first and secondary thickenings of the sauce, controlling the exhaust valve to remain open for strong pressure relief at this time will not cause liquid to overflow, that is, it will not affect the user's cooking experience.

[0109] In some embodiments of step S2, based on the foregoing solution, the cooking appliance is provided with an exhaust valve. Controlling the cooking appliance to perform secondary thickening of the sauce according to the second pressure includes:

[0110] Step S21B. Control the exhaust valve to remain open;

[0111] Step S22B. Determine the second heating power according to the second pressure;

[0112] Step S23B. Control the cooking appliance to operate at the second heating power so that the liquid in the cavity boils to achieve secondary thickening of the sauce.

[0113] It can be understood that after the first thickening of the sauce ends, controlling the exhaust valve to remain open enables the cooking appliance to continuously relieve pressure during the secondary thickening of the sauce, further shortening the cooking time. Therefore, the second pressure may drop to zero pressure during the pressure relief process, that is, the secondary thickening of the sauce is completed under low pressure or zero pressure.

[0114] In some embodiments of step S2, based on the foregoing solution, the cooking appliance is provided with an exhaust valve. Controlling the cooking appliance to perform secondary thickening of the sauce according to the second pressure includes:

[0115] Step S21C. Control the exhaust valve to remain open until the second preset time so that the pressure in the cavity of the cooking appliance drops below the pressure threshold;

[0116] It can be understood that after the first thickening is completed, the exhaust valve is controlled to remain open for pressure relief. When the exhaust valve has been open for a second preset time, the pressure inside the cooking appliance drops below the pressure threshold, for example, below 4000 Pa. At this time, the user can manually open the electric pressure upper cover.

[0117] Step S22C. In response to a signal indicating that the upper cover of the cooking appliance is opened, control the cooking appliance to operate at a third heating power in a zero-pressure state to cause the liquid inside the cavity to boil and achieve secondary thickening.

[0118] For example: send a prompt message to the user indicating that the upper cover of the cooking appliance can be opened currently. If the user manually opens the upper cover of the cooking appliance, after the cooking appliance detects that the upper cover is opened, it can control the cooking appliance to operate at a third heating power in a zero-pressure state. That is to say, the second pressure at this time drops to zero, so that secondary thickening can be achieved in the open-lid state, further shortening the cooking time; in addition, when thickening is carried out with the lid open, the ingredients can be placed in an environment with sufficient oxygen, thus bringing a better oxygen flavor enhancement effect to the ingredients.

[0119] In some embodiments of the present application, based on the foregoing solution, a temperature control module is provided at the bottom of the cooking appliance. Obtaining a second exit signal for secondary thickening includes:

[0120] Obtain the duration of secondary thickening; and / or obtain the bottom temperature detected by the temperature control module;

[0121] Among them, a signal indicating that the duration of secondary thickening reaches the time threshold, and / or a signal indicating that the bottom temperature reaches the second preset threshold is used to represent the second exit signal for secondary thickening.

[0122] It can be understood that when using one of the duration of secondary thickening and the bottom temperature as a signal to determine the end of the secondary thickening stage, it can be to only detect the duration of secondary thickening or only detect the bottom temperature of the cooking appliance; it can also be to simultaneously detect the duration of secondary thickening and the bottom temperature of the cooking appliance. Among them, when detecting both signals simultaneously, it can be to stop detecting the other signal when obtaining one of the threshold signals first. For example: if it is first detected that the duration reaches the time threshold, it is considered that the second exit signal for secondary thickening is obtained, and the detection of the bottom temperature is stopped, so that the cooking time can be shortened on the premise of ensuring that the secondary thickening meets the preset exit conditions.

[0123] In some embodiments, obtain the duration of secondary thickening and the bottom temperature detected by the temperature control module. If the duration of secondary thickening reaches the time threshold and the bottom temperature reaches the second preset threshold, then obtain the second exit signal for secondary thickening.

[0124] It should be noted that when the duration of the second sauce reduction and the bottom temperature detected by the temperature control module are jointly used as signals to determine the end of the second sauce reduction stage, the two can be combined to determine whether the second sauce reduction meets the preset exit conditions, ensuring the effect of the second sauce reduction.

[0125] In some embodiments, the time threshold for the second sauce reduction can range from 1 minute to 3 minutes.

[0126] In some embodiments, the second preset threshold for the bottom temperature can range from 130°C to 135°C.

[0127] For ease of understanding, the following takes "cooking braised pork" as an example to illustrate the implementation of the sauce reduction control method of the cooking appliance according to the embodiments of the present application:

[0128] I. Preparation stage: The user places 1000g of braised pork ingredients in the cooking appliance and adds about 100g of water.

[0129] II. Heating and pressure increasing cooking stage. After the cooking appliance is started, the bottom heating module operates at an average heating power of 2200W to raise the temperature and pressure in the cavity to the preset temperature and pressure, for example, the pressure is raised to 70 kPa, and this stage lasts for 4 minutes and 10 seconds.

[0130] III. Pressure maintaining cooking stage. The cooking appliance closes the exhaust valve, the cavity is in a sealed state, the bottom heating module stops heating, and pressure maintaining cooking is carried out in the cavity. This stage lasts for 10 minutes.

[0131] IV. High-pressure sauce reduction cooking stage. The first pressure of the cooking appliance is maintained at about 70 kPa, the exhaust valve exhausts at the first exhaust frequency of exhausting for 4 seconds every 10 seconds, and the average heating power of the bottom heating module is greater than 1500W, so that the liquid in the cavity is continuously heated and boiled for the first sauce reduction until the bottom temperature reaches 120°C. This stage lasts for about 5 minutes.

[0132] V. Low-pressure sauce reduction cooking stage. The exhaust valve of the cooking appliance increases the exhaust frequency, so that the cavity performs the second sauce reduction in a low-pressure or non-pressure state, further accelerating the sauce reduction time until the bottom temperature reaches 130°C.

[0133] VI. Pressure relief stage. Based on the high-pressure sauce reduction and low-pressure sauce reduction stages, at this time, the liquid volume in the cavity is very small, so strong pressure discharge is carried out to further shorten the cooking time.

[0134] Based on the above - disclosed content, after the pressure - maintaining cooking of the cooking appliance reaches the first preset time, the embodiments of the present application control the cooking appliance to perform a first stage of liquid - reducing at the first pressure and the first exhaust frequency, so as to reduce the liquid in the cavity without reducing the cooking efficiency of the cooking appliance; after the first stage of liquid - reducing is completed, the cooking appliance is controlled to perform a second stage of liquid - reducing at the second pressure until a second exit signal for the second stage of liquid - reducing is obtained. The second pressure is less than the first pressure. Thus, by means of variable - pressure liquid - reducing, not only the viscosity of the liquid - reduced ingredients is enhanced, promoting the flavoring and aroma - increasing of the ingredients during liquid - reducing, but also the cooking time of the cooking appliance is shortened, improving the cooking efficiency.
