Based on the hardware structure, various embodiments of the pressure control method of the present invention are proposed.

The invention provides a pressure control method.

Referring to fig. 2, fig. 2 is a schematic flow chart of a pressure control method according to a first embodiment of the present invention.

In the present embodiment, the pressure control method is applied to a cooking appliance, and includes the following steps S10 to S30:

step S10, when the heating device is in a boiling stage, acquiring a large power modulation ratio and a small power modulation ratio of the heating device, wherein the large power modulation ratio is larger than the small power modulation ratio;

in this embodiment, the pressure control method is implemented by a cooking appliance, the cooking appliance includes a heating device, specifically, referring to fig. 3, fig. 3 is a schematic structural diagram of the cooking appliance according to the embodiment of the present invention, and fig. 3 includes a sealing ring and a pressure relief hole in addition to the heating device 1. The heating device is used for heating food, water, gas and the like in the cooking appliance so as to boil the water in the cooking appliance and cook the food in the cooking appliance.

In one embodiment, the cooking device includes a boiling stage, a bumping and pressure-releasing stage, and a stewing stage. Firstly, a boiling stage is entered to boil water in the cooking appliance, and a current cooking program is determined in the boiling stage, so that a subsequent boiling stage carries out corresponding heating work based on the current cooking program. The boiling stage can comprise a plurality of stages, each boiling stage can also comprise a plurality of heating stages, and an bumping decompression stage can be included between each boiling stage. The stewing stage is the stage after all boiling stages are executed. Wherein, in boiling stage and the stage of braising, can push sealing washer partially or totally to sealed pressure release hole, not sealed pressure release hole or part sealed pressure release hole, and then realize pressurize and pressure release operation. The sealing ring can be pushed completely in the boiling stage to seal the pressure relief hole, so that the pressure maintaining operation is realized. The sealing ring can be partially pushed or completely pushed in the bumping pressure relief stage so as to partially seal the pressure relief hole or not seal the pressure relief hole, and further realize the pressure relief operation.

Wherein, the ratio of the power adjusting ratio represents the ratio of the heating time or the heating power, which is used for indicating the specific process of the heating work. Specifically, the large duty ratio is used to rapidly increase the pressure within the cooking appliance, i.e., to near the target pressure value, and then the small duty ratio is used to increase the pressure to the target pressure value and is maintained for 15 seconds or more, for example, 15 to 30 seconds. It will be appreciated that it is not possible to heat in the full work regime, and therefore the turndown ratio is typically less than 1, i.e. the high turndown ratio is a ratio less than 1, e.g. 6/16, 10/16, and the low turndown ratio is also a ratio less than 1, e.g. 1/16, 5/16.

It should be noted that, when the pressure in the cooking appliance is far from the target pressure value, the heating operation may be performed according to a large duty ratio, so that the pressure in the cooking appliance is rapidly increased, thereby increasing the cooking speed. When the pressure in the cooking appliance is closer to the target pressure value, in order to realize accurate pressure control, heating work can be carried out according to a small power adjustment ratio, namely slow heating work is carried out, so that the pressure in the cooking appliance is slowly changed, and accurate pressure control is realized. Therefore, the large power ratio must be larger than the small power ratio, and in one boiling stage, the boosting operation corresponding to the large power ratio is performed before, and the voltage stabilizing operation corresponding to the small power ratio is performed after, that is, in one boiling stage, the heating stage at the previous time is heated at the large power ratio, and the heating stage at the later time is heated at the small power ratio.

In some embodiments, after the boiling stage, the boiling stage may include a plurality of stages, for example, the boiling stage includes five stages, where the first stage may include 0 or more than 0 heating stages, that is, the first stage may not be present, or the first stage may include 1 or more heating stages, and if the plurality of heating stages are included, a plurality of power modulation ratios are correspondingly included in the plurality of heating stages, and at this time, the plurality of power modulation ratios may be divided into a large power modulation ratio and a small power modulation ratio according to a time sequence of the heating stages, that is, the large power modulation ratio may include a large power modulation ratio 1, a large power modulation ratio 2, and the like, and the small power modulation ratio may include a small power modulation ratio 1, a small power modulation ratio 2. After the first boiling stage, the pressure relief hole can be sealed to increase the pressure in the cooking appliance when the second boiling stage is entered. For example, if the second boiling stage includes 2 heating stages, the duty ratio corresponding to the first heating stage is a large duty ratio, and the duty ratio corresponding to the second heating stage is a small duty ratio. For example, if 3 heating stages are included, the duty ratio corresponding to the first heating stage is a large duty ratio, and the duty ratios corresponding to the second heating stage and the third heating stage are small duty ratios.

It should be noted that different power adjustment ratios correspond to different total heating times, that is, different large power adjustment ratios correspond to different total heating times, such as 112 seconds and 176 seconds, and different small power adjustment ratios correspond to different total heating times, such as 64 seconds and 96 seconds. The specific total heating time varies according to the ambient pressure, and generally, the greater the ambient pressure, the longer the total heating time. In addition, the total heating time also varies depending on the amount of food in the cooking appliance, and generally, the more the amount of food, the longer the total heating time. The environmental pressure can be graded and then mapped with the total heating time, and the environmental pressure can also be directly mapped with the total heating time, so that the total heating time can be determined according to the environmental pressure. Correspondingly, the mapping relation between the food material amount and the total heating time is substantially the same as the ambient pressure, and the details are not repeated here.

It can be understood that the large power modulation ratio and the small power modulation ratio corresponding to different cooking programs are different, and correspondingly, the total heating time corresponding to the large power modulation ratio and the small power modulation ratio is different from the actual heating time. How to select and determine the cooking program can refer to the following sixth embodiment, which is not described in detail herein.

Step S20, controlling the heating device to carry out boosting operation at the large power regulation ratio;

after obtaining the large power adjustment ratio, controlling the heating device of the cooking appliance to perform boosting operation at the large power adjustment ratio so as to rapidly increase the pressure in the cooking appliance. The boosting operation is a heating operation mode of the heating device, and the boosting operation is used for rapidly increasing the pressure in the cooking appliance.

In an embodiment, different large power ratios correspond to different total heating times, so that the corresponding total heating time needs to be determined according to the large power ratios, and then the total heating time is multiplied by the large power ratios to obtain the actual heating time corresponding to the large power ratios. For example, when the total heating time is 176 seconds and the large duty ratio is 6/16, the actual heating time is 66 seconds. Therefore, in actual implementation, the heating device is controlled to perform the heating operation for the actual heating time. The heating operation performed in the actual heating time is usually performed in a periodic manner, and the specific implementation process may refer to the following second embodiment, which is not described in detail herein.

In another embodiment, the total power may also be set, then the large power regulation ratio is multiplied by the total power to obtain the corresponding actual power, and finally the heating device is controlled to perform the heating operation with the actual power.

And step S30, after the boosting operation is finished, controlling the heating device to perform voltage stabilization operation at the small power regulation ratio.

After the small power adjustment ratio is obtained and after the boosting operation of the step S20 is finished, the heating device of the cooking appliance is controlled to perform the voltage stabilization operation at the small power adjustment ratio so that the pressure in the cooking appliance is slowly increased or approaches the target value. The pressure stabilizing operation is a heating operation mode of the heating device, and the pressure stabilizing operation is used for slowly increasing or approaching the pressure in the cooking utensil to a target value.

In an embodiment, different small power ratios correspond to different total heating times, so that the corresponding total heating time needs to be determined according to the small power ratios, and then the total heating time is multiplied by the small power ratios to obtain the actual heating time corresponding to the small power ratios. For example, if the total heating time is 112 seconds and the small duty ratio is 5/16, the actual heating time is 35 seconds. Therefore, in actual implementation, the heating device is controlled to perform the heating operation for the actual heating time. The heating operation performed in the actual heating time is usually performed in a periodic manner, and the specific implementation process may refer to the following third embodiment, which is not described in detail herein.

In another embodiment, the total power may be set, then the small power modulation ratio is multiplied by the total power to obtain the corresponding actual power, and finally the heating device is controlled to perform the heating operation with the actual power.

The embodiment of the invention provides a pressure control method, which is applied to a cooking appliance, wherein the cooking appliance comprises a heating device, and a large power modulation ratio and a small power modulation ratio of the heating device are obtained when the cooking appliance is in a boiling stage, wherein the large power modulation ratio is larger than the small power modulation ratio; controlling a heating device to perform boosting operation at a large power regulation ratio; and after the boosting operation is finished, controlling the heating device to perform voltage stabilization operation at a small power regulation ratio. By the mode, in a boiling stage, heating work is carried out at a large power regulation ratio to increase the pressure in the cooking utensil to be close to a target value, then, heating work is carried out at a small power regulation ratio to slowly increase the pressure in the cooking utensil to be the target value, and after the target value is reached, because the heating device still carries out pressure stabilization work at the small power regulation ratio, the pressure in the cooking utensil can be maintained at the target value for a period of time, so that accurate pressure control is realized based on the stable pressure in the cooker. Simultaneously, cooking utensil heats work with little turn-ups ratio to slowly rise to the target value and maintain a period with the pressure in the cooking utensil, can solve the problem that the temperature sensor that sets up in the cooking utensil detects the hysteresis, pressure in the cooking utensil can not the rapid change promptly, even there is temperature detection hysteresis, also can realize accurate accuse pressure. In conclusion, the embodiment of the invention improves the pressure control accuracy of the cooking appliance and ensures the cooking effect of the cooking appliance.

Further, based on the above-described first embodiment, a second embodiment of the pressure control method of the present invention is proposed.

Referring to fig. 4, fig. 4 is a flow chart illustrating a pressure control method according to a second embodiment of the present invention.

In the present embodiment, the above step S20 includes the following steps S21 to S23:

step S21, determining a current cooking program, and acquiring first total heating time corresponding to the large power modulation ratio according to the current cooking program;

in this embodiment, the current cooking program is determined before entering the boiling phase. Therefore, the current cooking program can be directly determined, and the first total heating time corresponding to the large power modulation ratio can be obtained according to the mapping table of the power modulation ratio and the total heating time preset in the current cooking program. The first total heating time is the total duration of the current heating stage, and comprises actual heating time and heating stopping time, wherein the actual heating time is the time when the heating device really works, and the heating stopping time is the time when the heating device stops working.

It should be noted that the large power adjustment ratios corresponding to different cooking programs are different, and correspondingly, the total heating time corresponding to the large power adjustment ratio is different from the actual heating time. How to select and determine the cooking program can refer to the following sixth embodiment, which is not described in detail herein.

In addition, it should be noted that the large power adjustment ratio is also determined by the current cooking program, and the specific execution flow may refer to the following fourth embodiment, which is not described in detail herein. Based on this, the mapping relation between the large power modulation ratio and the corresponding first total heating time is also determined by the current cooking program. The mapping relationship can be obtained by experiments and is preset in the corresponding cooking program.

In some embodiments, the large power modulation ratio may include a plurality of power modulation ratios, that is, a plurality of heating stages with large power modulation ratios need to be performed, and at this time, the total heating time corresponding to each large power modulation ratio may be obtained correspondingly, and the total heating time corresponding to each large power modulation ratio may be different. Subsequently, heating operation is performed according to the time sequence of the heating stage corresponding to the large power modulation ratio.

Step S22, determining first actual heating time corresponding to the large power modulation ratio according to the first total heating time and the large power modulation ratio;

after the first total heating time is obtained, according to the first total heating time and the large power modulation ratio, first actual heating time corresponding to the large power modulation ratio is determined. Specifically, the first total heating time may be multiplied by a corresponding large duty ratio, and then the calculation result may be used as the first actual heating time.

For example, if the first total heating time is 176 seconds and the large turn ratio is 6/16, the first actual heating time is 66 seconds.

In some embodiments, the large duty ratio may include a plurality of duty ratios, and accordingly, the first actual heating time may include a plurality of actual heating times. Subsequently, heating operation is performed according to the time sequence of the heating stage corresponding to the large power modulation ratio.

And step S23, controlling the heating device to perform boosting operation according to the first actual heating time.

And finally, controlling a heating device of the cooking appliance to perform boosting operation for the first actual heating time so as to rapidly increase the pressure in the cooking appliance. The pressure increasing operation is a heating operation mode of the heating device, and the pressure increasing operation is used for rapidly increasing the pressure in the cooking utensil.

In some embodiments, the large power modulation ratio may include a plurality of power modulation ratios, and correspondingly, the first actual heating time may include a plurality of actual heating times, and at this time, it is only necessary to control the heating device of the cooking appliance to perform the boosting operation with the corresponding first actual heating time according to a sequence of time of the heating stage corresponding to the large power modulation ratio.

In one embodiment, within the first total heating time, the heating device is controlled to perform the boosting operation with the first actual heating time, and then the heating device is controlled to stop heating until the first total heating time is reached. Or, in the first total heating time, controlling the heating device to stop heating in the heating stop time, wherein the heating stop time is the difference between the first total heating time and the first actual heating time, and then controlling the heating device to perform boosting operation in the first actual heating time.

In another embodiment, the denominator of the large duty ratio is taken as the period, for example, the large duty ratio is 10/16, in the current heating stage, every 16 seconds, the heating is performed for 10 seconds, and the remaining 6 seconds are stopped, and then the period is continuously changed until the first total heating time is reached. In other embodiments, the periodic replacement may be performed in other manners, which are not limited herein.

Specifically, the step S23 includes:

step a231, determining a first heating period according to the large power modulation ratio, and determining a first period number according to the first total heating time and the first heating period;

step a232, determining the actual heating time of a first period according to the first period number and the first actual heating time;

step a233, controlling the heating device to perform the boosting operation within the first heating period and within the first period actual heating time until the first period is executed.

In this embodiment, the denominator of the large power modulation ratio may be used as the first heating period, or the denominator of the large power modulation ratio may be multiplied by a corresponding multiple to be used as the first heating period. Then, the quotient of the first total heating time and the first heating period is taken as the first period number. Then, the quotient of the first actual heating time and the first cycle number is used as the first cycle actual heating time. And finally, controlling the heating device to perform boosting work within the first heating period according to the actual heating time of the first period until the first period is executed.

The first heating period is the total time of one heating period, the first period number represents the number of the heating periods included in the current heating stage, and the actual heating time of the first period is the actual heating time of the heating device in one heating period.

For example, if the large duty ratio is 10/16 and the first total heating time is 176 seconds, the first heating period may be 16 seconds, the first number of periods may be 11, and the actual heating time of the first period is 10 seconds. That is, the current heating stage includes 11 heating cycles, the total time of each heating cycle is 16 seconds, the actual heating time of each heating cycle is 10 seconds, and the remaining 6 seconds are the stop heating time.

In this embodiment, through calculating actual heating time to control cooking utensil's heating device carries out heating work according to actual heating time, so that in a heating stage, control heating device's start work and stop work, thereby improve cooking utensil's intellectuality, and further improve cooking utensil's culinary art effect.

Further, based on the above-described first embodiment, a third embodiment of the pressure control method of the present invention is proposed.

Referring to fig. 5, fig. 5 is a flow chart illustrating a third embodiment of the pressure control method according to the present invention.

In the present embodiment, the step S30 includes the following steps S31 to S33:

step S31, determining a current cooking program, and acquiring second total heating time corresponding to the small power adjustment ratio according to the current cooking program;

in this embodiment, the current cooking program is determined before entering the boiling phase. Therefore, the current cooking program can be directly determined, and the second total heating time corresponding to the small power modulation ratio can be obtained according to the mapping table of the power modulation ratio and the total heating time preset in the current cooking program. The second total heating time is the total duration of the current heating stage, and includes actual heating time and heating stop time, the actual heating time is the time when the heating device really works, and the heating stop time is the time when the heating device stops working.

It should be noted that the small power adjustment ratios corresponding to different cooking programs are different, and correspondingly, the total heating time corresponding to the small power adjustment ratios is different from the actual heating time. How to select and determine the cooking program can refer to the following sixth embodiment, which is not described in detail herein.

In addition, it should be noted that the minor turn ratio is also determined by the current cooking program, and the specific execution flow may refer to the following fourth embodiment, which is not described herein again. Based on this, the mapping relationship between the small power adjustment ratio and the corresponding second total heating time is also determined by the current cooking program. The mapping relationship can be obtained through experiments and is preset in the corresponding cooking program.

In some embodiments, the small power adjustment ratio may include a plurality of power adjustment ratios, that is, a heating stage requiring a plurality of small power adjustment ratios is performed, and at this time, the total heating time corresponding to each small power adjustment ratio may be obtained correspondingly, and the total heating time corresponding to each small power adjustment ratio may be different. Subsequently, heating operation is performed according to the time sequence of the heating stage corresponding to the small power adjustment ratio.

Step S32, determining second actual heating time corresponding to the small power modulation ratio according to the second total heating time and the small power modulation ratio;

and after obtaining the second total heating time, determining second actual heating time corresponding to the small modulation ratio according to the second total heating time and the small modulation ratio. Specifically, the second total heating time may be multiplied by the corresponding small turn ratio, and then the calculation result may be used as the second actual heating time.

For example, if the second total heating time is 116 seconds and the small duty ratio is 5/16, the second actual heating time is 35 seconds.

In some embodiments, the small turndown ratio may include a plurality of turndown ratios, and accordingly, the second actual heating time may include a plurality of actual heating times. Subsequently, heating operation is performed according to the time sequence of the heating stage corresponding to the small power adjustment ratio.

And step S33, controlling the heating device to perform voltage stabilization operation within the second actual heating time.

And finally, controlling the heating device of the cooking appliance to perform pressure stabilization operation at the second actual heating time so as to slowly increase or approach the pressure in the cooking appliance to the target value. The pressure stabilizing operation is a heating operation mode of the heating device, and the pressure stabilizing operation is used for slowly increasing or approaching the pressure in the cooking utensil to a target value.

In some embodiments, the small power adjustment ratio may include a plurality of power adjustment ratios, and correspondingly, the second actual heating time may include a plurality of actual heating times, and at this time, it is only necessary to control the heating apparatus of the cooking appliance to perform the voltage stabilization operation with the corresponding second actual heating time according to the sequence of the time of the heating stage corresponding to the small power adjustment ratio.

In one embodiment, during the second total heating time, the heating device is controlled to perform the boosting operation for the second actual heating time, and then the heating device is controlled to stop heating until the second total heating time is reached. Or, in the second total heating time, controlling the heating device to stop heating in the heating stop time, wherein the heating stop time is the difference between the second total heating time and the second actual heating time, and then controlling the heating device to perform the voltage stabilization operation in the second actual heating time.

In another embodiment, the period is the denominator of the small duty ratio, for example, the small duty ratio is 5/16, and in the current heating stage, every 16 seconds, the heating is performed for 5 seconds, and the remaining 11 seconds are stopped, and then the period is continuously changed until the second total heating time is reached. In other embodiments, the periodic replacement may be performed in other manners, which are not limited herein.

Specifically, the step S33 includes:

step a331, determining a second heating period according to the small modulation ratio, and determining a second period number according to the second total heating time and the small modulation ratio;

step a332, determining the actual heating time of the second period according to the second period number and the second actual heating time;

step a333, controlling the heating device to perform voltage stabilization operation within the second heating period and the actual heating time of the second period until the second period is executed.

In this embodiment, the denominator of the small dimming ratio may be used as the second heating period, or the denominator of the small dimming ratio may be multiplied by a corresponding multiple to be used as the second heating period. Then, the quotient of the second total heating time and the second heating period is taken as the second period number. And then, taking the quotient of the second actual heating time and the second period number as the second period actual heating time. And finally, controlling the heating device to perform voltage stabilization work within the second heating period according to the actual heating time of the second period until the second period is executed.

The second heating period is the total time of one heating period, the second period number represents the number of the heating periods included in the current heating phase, and the actual heating time of the second period is the actual heating time of the heating device in one heating period.

For example, if the small duty ratio is 5/16 and the second total heating time is 112 seconds, the second heating period may be 16 seconds, the second number of cycles may be 7, and the second actual heating time period is 5 seconds. That is, the current heating phase includes 7 heating cycles, the total time of each heating cycle is 16 seconds, the actual heating time of each heating cycle is 5 seconds, and the remaining 11 seconds are the stop heating time.

In this embodiment, through calculating actual heating time to control cooking utensil's heating device carries out heating work according to actual heating time, so that in a heating stage, control heating device's start work and stop work, thereby further improve cooking utensil's intelligence, and further improve cooking utensil's culinary art effect.

Further, based on the above-described first embodiment, a fourth embodiment of the pressure control method of the present invention is proposed.

In the present embodiment, the above step S10 includes the following steps a11 to a12:

step a11, determining a current cooking program when the cooking device is in a boiling stage;

in this embodiment, the boiling stage may comprise a plurality of heating stages. And the heating stage and the corresponding power adjusting ratio are determined by the current cooking program. Wherein the current cooking program is determined before entering the boiling phase. Therefore, the current cooking program can be directly determined, so that the large power regulation ratio of boosting operation and the small power regulation ratio of voltage stabilization operation can be determined according to the heating stage and the corresponding power regulation ratio which are preset in the current cooking program.

It should be noted that the heating stages and the power adjusting ratios thereof are different for different cooking programs. How to select and determine the cooking program can refer to the following sixth embodiment, which is not described in detail herein.

Step a12, determining power adjustment ratios corresponding to a plurality of heating stages according to the current cooking program, wherein the heating stage at the previous time corresponds to a large power adjustment ratio, and the heating stage at the later time corresponds to a small power adjustment ratio.

In this embodiment, the current cooking program is determined before entering the boiling phase. Therefore, the current cooking program can be directly determined, so that the power regulation ratio corresponding to each heating stage is determined according to the mapping relation between the heating stage and the power regulation ratio preset in the current cooking program. Wherein the power modulation ratio comprises a large power modulation ratio and a small power modulation ratio.

It should be noted that, when the pressure in the cooking appliance is far from the target pressure value, the heating operation should be performed according to a large power adjustment ratio, so that the pressure in the cooking appliance is rapidly increased, and the cooking speed is increased. Therefore, the preceding heating stage should be a large work adjustment. When the pressure in the cooking appliance is closer to the target pressure value, in order to accurately control the pressure, heating work is carried out according to a small power adjustment ratio, namely slow heating work is carried out, so that the pressure in the cooking appliance is slowly changed, and accurate pressure control is realized. Therefore, the heating phase at the end should be a small work adjustment. Specifically, the power regulation ratio is divided into a large power regulation ratio and a small power regulation ratio according to the time sequence of the heating stage.

Wherein, the ratio of the power adjusting ratio represents the ratio of the heating time or the heating power, which is used for indicating the specific process of the heating work. The power adjusting ratio is a ratio less than 1, such as 6/16, 10/16, 1/16, 5/16.

The large power ratio must be larger than the small power ratio, and in a boiling stage, the boosting operation corresponding to the large power ratio is performed before and the voltage stabilizing operation corresponding to the small power ratio is performed after.

In a specific implementation, after the boiling stage, the boiling stage may include a plurality of stages, for example, the boiling stage includes five stages, where the first stage may include 0 or more than 0 heating stages, that is, the first stage may be absent, or the first stage may include 1 or more heating stages, and if the plurality of heating stages are included, a plurality of power adjusting ratios correspond to the plurality of heating stages. And is divided into a large power modulation ratio and a small power modulation ratio according to the sequence of the heating stage. After the first boiling stage, the pressure relief hole can be sealed to increase the pressure in the cooking appliance when the second boiling stage is entered. For example, if the second boiling stage includes 2 heating stages, the power adjustment ratio corresponding to the first heating stage is large, and the power adjustment ratio corresponding to the second heating stage is small. For example, when 3 heating stages are included, the power adjustment ratio corresponding to the first heating stage is large power adjustment, the second heating stage and the third heating stage are small power adjustment, and accordingly, after voltage stabilization operation is performed according to the small power adjustment corresponding to the second heating stage, voltage stabilization operation can be performed according to the small power adjustment corresponding to the third heating stage.

In some embodiments, during a boiling phase, the heating phase operating at a high turn-down ratio may include 1 or more, and the heating phase operating at a low turn-down ratio may also include 1 or more.

In one embodiment, the step a12 includes the following steps a121-a122:

step a121, determining a large power modulation ratio corresponding to the heating stage with the first time sequence according to the current cooking program;

in this embodiment, if the current boiling stage includes more than 2 heating stages, the chronological order of the heating stages is obtained, and the power adjustment ratio corresponding to the heating stage with the chronological order being the first is taken as the large power adjustment ratio according to the chronological order.

Step a122, according to the current cooking program, determining a small power ratio corresponding to the heating stage of which the time sequence is not the first, wherein the small power ratio includes 1 or more.

Then, the power adjustment ratios corresponding to the heating stages which are not the first before and after the time sequence are used as small power adjustment ratios, wherein the small power adjustment ratios comprise 1 or more power adjustment ratios.

When the small duty ratios include a plurality of small duty ratios and the boosting operation is completed, the heating devices are controlled to perform the voltage stabilizing operation at the corresponding small duty ratios.

In this embodiment, when the boiling stage includes a plurality of heating stages, the power adjustment ratio corresponding to the heating stage is divided into a large power adjustment ratio and a small power adjustment ratio, so that the subsequent heating operation is performed with the large power adjustment ratio first, so as to raise the pressure in the cooking appliance to a value near the target value, and then the heating operation is performed with the small power adjustment ratio, so as to slowly raise the pressure in the cooking appliance to the target value, and after the target value is reached, because the heating device performs the pressure stabilizing operation, the pressure in the cooking appliance can be maintained at the target value for a period of time, thereby implementing the accurate pressure control, and further improving the pressure control accuracy of the cooking appliance.

Further, a fifth embodiment of the pressure control method of the present invention is proposed based on the above-described first embodiment.

In the present embodiment, after the above-described step S30, the pressure control method further includes the following steps a to D:

step A, entering a bumping pressure relief stage after the pressure stabilizing work is finished;

firstly, when the pressure stabilizing work time is up, the sealing ring is pushed to open the pressure relief hole so as to enter the bumping pressure relief stage. It can be understood that the heating time with the small power adjustment ratio corresponding to the pressure stabilizing working time is determined by the cooking program, and the preset heating time in the cooking program can be obtained according to an experiment, specifically, the time when the pressure in the cooking appliance reaches the bumping pressure is taken as the experimental data in the experiment to obtain the pressure stabilizing working time. The pressure of the bumping is different under different environmental pressures, and the pressure difference between the pressure at bumping and the environment can be considered approximately equal.

Step B, determining a current cooking program, and determining a pressure relief and power regulation ratio corresponding to the bumping pressure relief stage according to the current cooking program;

in the sudden-boiling pressure-relief stage, 1 or more heating stages may be included, and if 1 heating stage is included, the current cooking program may be directly determined, so as to determine the pressure-relief power-regulation ratio corresponding to the current sudden-boiling pressure-relief stage according to a mapping relationship between the sudden-boiling pressure-relief stage and the pressure-relief power-regulation ratio preset in the current cooking program.

It should be noted that, if a plurality of heating stages are included, the execution flow of each heating stage is substantially the same, and details are not repeated here.

In one embodiment, since the pressure in the cooking utensil does not drop below the target value in the first time in the bumping pressure relief stage, especially in the beginning of bumping pressure relief, the pressure in the cooking utensil is still in a high state, and therefore, the pressure relief and power adjustment ratio is small.

Step C, controlling the heating device to carry out bumping pressure relief work according to the pressure relief power regulation ratio;

after the pressure relief and power regulation ratio is obtained, the heating device of the cooking appliance is controlled to perform bumping pressure relief work according to the pressure relief and power regulation ratio so as to improve the agglomeration problem of the rice, optimize the taste of the rice and further improve the cooking effect.

In an embodiment, different pressure relief and power regulation ratios correspond to different total heating times, so that the corresponding total heating time needs to be determined according to the pressure relief and power regulation ratios, and then the total heating time is multiplied by the pressure relief and power regulation ratios to obtain the actual heating time corresponding to the pressure relief and power regulation ratios. For example, if the total heating time is 112 seconds, the pressure/power ratio is 5/16, and the actual heating time is 35 seconds. Therefore, in actual implementation, the heating device is controlled to perform the heating operation for the actual heating time. The heating operation performed within the actual heating time is usually performed in a periodic manner, and the specific execution process may refer to the second embodiment, which is not described in detail herein.

In another embodiment, the total power may also be set, then the pressure relief power regulation ratio is multiplied by the total power to obtain the corresponding actual power, and finally the heating device is controlled to perform the heating operation with the actual power.

And D, after the sudden boiling pressure relief work is finished, returning to the step of obtaining the large power regulation ratio and the small power regulation ratio of the heating device when the sudden boiling pressure relief work is in a boiling stage until the plurality of boiling stages are finished.

In this embodiment, after the boiling stage, the bumping pressure relief stage may be entered, and after the bumping pressure relief stage, the boiling stage may be returned again. When all boiling stages are completed, the rice stewing stage can be entered.

Wherein, the bumping decompression phase can include 1 or more, if the bumping phase is 1, the boiling phase includes at least 2, if the bumping phase is 2, the boiling phase includes at least 3. The bumping pressure of each bumping pressure relief stage may be the same or different, and is not limited herein.

For example, in a cooking procedure, first, a first boiling stage performs a heating stage with a large power ratio, after the heating stage is completed, a pressure relief hole of a cooking appliance is sealed to enter a second boiling stage, the second boiling stage includes 2 heating stages, the first heating stage in time sequence is a heating stage with a large power ratio, the second heating stage in time sequence is a heating stage with a small power ratio, after the two heating stages are completed, when the pressure in the cooking appliance rises to a sudden boiling pressure, the pressure relief hole is opened to enter a sudden boiling pressure relief stage (i.e., a third boiling stage), in the sudden boiling pressure relief stage, the first heating stage is performed with a small power ratio, after the heating stage is completed, the pressure relief hole of the cooking appliance is sealed to enter a fourth boiling stage, the fourth boiling stage includes 2 heating stages, the first heating stage in time sequence is a heating stage with a large power ratio, the second heating stage is a heating stage with a small power ratio, and after the two heating stages are opened to a pressure relief hole is opened to enter a fifth boiling stage (i.e., when the pressure in the first boiling stage).

In the embodiment, the boiling stage and the sudden boiling pressure relief stage are alternated, so that the sudden boiling pressure relief stage and the boiling stage can be realized effectively, the agglomeration problem of the rice is improved, the taste of the rice is optimized, and the cooking effect of the cooking utensil is further improved.

Further, based on the above-described first embodiment, a sixth embodiment of the pressure control method of the present invention is proposed.

Referring to fig. 6, fig. 6 is a flow chart illustrating a pressure control method according to a sixth embodiment of the present invention.

In the present embodiment, before the above step S10, the pressure control method further includes the following steps S40 to S50:

step S40, acquiring the environmental pressure of the cooking appliance and acquiring the food material amount of the cooking food material in the cooking appliance;

due to different environmental pressures, different corresponding bumping pressures and different corresponding food material quantity judgment standards, the total heating time corresponding to each power adjustment ratio in the heating stage is different. That is, the total heating time differs depending on the ambient pressure, and generally, the greater the ambient pressure, the longer the total heating time. In addition, the total heating time also varies according to the amount of food in the cooking appliance, and generally, the more the amount of food, the longer the total heating time. Therefore, the environmental pressure of the cooking device and the amount of the food material cooked in the cooking device need to be obtained to select the corresponding cooking program, and the large power ratio and the small power ratio in different cooking programs are different, and correspondingly, the corresponding total heating time is also different. Wherein, the total heating time is the total duration of the current heating stage, that is, the total duration of the heating stage corresponding to the power-adjusting ratio.

In one embodiment, the positioning information of the cooking appliance can be acquired through a WIFI (wireless fidelity) device configured on the cooking appliance, so that the use area of the cooking appliance can be known, the environmental pressure can be determined according to the use area, and the environmental pressure can be stored in the cooking appliance for acquiring the environmental pressure of the cooking device. In another embodiment, the ambient pressure may be detected by an ambient pressure sensor disposed outside the cooking appliance.

In some embodiments, the amount of the material cooked in the cooking appliance may be determined by detecting a pressure value according to a pressure sensor disposed at the bottom of the cooking appliance and determining the amount of the material according to the pressure value.

In an embodiment, in the step S40, the step of obtaining the amount of the material cooked in the cooking appliance includes the following steps a41 to a43:

step a41, acquiring the heating starting time of the heating device and acquiring the boiling time in the cooking appliance;

the timer is arranged in the cooking appliance, and can acquire the heating starting time of the heating device, namely after a user puts food materials, such as rice, coarse cereals and the like, and when a cooking starting instruction is triggered, the current time is acquired as the starting heating time.

In addition, during the heating process, whether the inside of the cooking appliance is boiled, that is, whether water in the cooking appliance is boiled or not can be detected through a temperature sensor arranged in the cooking appliance, and if the boiling is detected, the current time is taken as the boiling time.

Step a42, determining boiling time according to the heating starting time and the boiling time;

then, the boiling time is determined from the heating start time and the boiling time. Specifically, the boiling time is obtained by subtracting the boiling time from the heating start time.

Wherein the boiling time is related to the amount of food materials, and the boiling time is longer when the amount of the food materials is larger; the smaller the amount of food material, the shorter the boiling time. Meanwhile, the boiling time is also related to the environmental pressure, and the larger the environmental pressure is, the longer the boiling time is, and the smaller the environmental pressure is, the shorter the boiling time is. Of course, the boiling time is related to the capacity of the cooking appliance or the power of the cooking appliance itself, and will not be described in detail here.

Step a43, determining the amount of the cooking materials in the cooking appliance according to the boiling time.

And finally, determining the amount of the food material cooked in the cooking appliance according to the boiling time.

The boiling time can be subjected to grading and then mapped with the food material amount, and the boiling time can be directly mapped with the food material amount to obtain a mapping relation table, so that the food material amount of the cooking food material in the cooking appliance can be determined according to the boiling time based on the mapping relation table.

For example, when the food material is rice, the rice is judged to be small rice under standard atmospheric pressure when the boiling time is 5-6 minutes; when the boiling time is 6-7 minutes, judging the rice quantity is medium; when the boiling time is 8-10 minutes, the rice is judged to be large.

And S50, determining a corresponding current cooking program according to the environmental pressure and the food material quantity, and entering a boiling stage so that the boiling stage works according to the current cooking program.

In this embodiment, a corresponding cooking program is determined according to the environmental pressure and the food material amount, and a boiling stage is entered, so that the boiling stage operates according to the cooking program. The plurality of cooking programs are determined when the cooking appliance leaves a factory, and different cooking programs comprise different numbers of boiling stages and different heating stages, namely different cooking programs comprise different power modulation ratios (large power modulation ratio and small power modulation ratio). It can be understood that after the cooking program is determined, the subsequent boiling stage only needs to work according to the cooking program, and accurate pressure control can be realized.

In this embodiment, the cooking program is determined according to the environmental pressure of the cooking appliance and the amount of the food material cooked in the cooking appliance. Then, the cooking device enters the boiling stage, and only the cooking program needs to be operated, that is, the operation of the first embodiment is realized, so that the intelligence of the cooking device is further improved.
