Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A heating control method of a pressure cooker, a heating control device of a pressure cooker, and a pressure cooker having the same according to embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a heating control method of a pressure cooker according to an embodiment of the present invention. As shown in fig. 1, the heating control method of the pressure cooker may include the steps of:
and S1, controlling the pressure cooker to work at a first preset power during the heating process of the pressure cooker, and acquiring the internal temperature or the internal pressure of the pressure cooker in real time.
The first preset power can be calibrated according to actual conditions, for example, the first preset power can be determined according to the type and cooking effect of food to be cooked.
Specifically, boiled rice is still exemplified. When the pressure cooker begins to heat rice water, the rice water can be heated with high power firstly, so that the rice water in the pressure cooker is boiled quickly, and in the process of heating the rice water, the internal temperature of the pressure cooker can be obtained in real time through a temperature sensor arranged in the pressure cooker, or the internal pressure of the pressure cooker is obtained in real time through a pressure sensor arranged in the pressure cooker.
And S2, judging whether the internal temperature of the pressure cooker is greater than a first preset temperature or whether the internal pressure of the pressure cooker is greater than a first preset pressure.
The first preset temperature and the first preset pressure may be calibrated according to actual conditions, for example, the first preset temperature may be 101 ℃ to 112 ℃, and the first preset pressure may be 5kPa to 50 kPa.
And S3, if the internal temperature of the pressure cooker is higher than a first preset temperature or the internal pressure of the pressure cooker is higher than a first preset pressure, controlling the pressure cooker to start pressure relief, and controlling the pressure cooker to stop heating or to heat with preset low power so as to enable food in the pressure cooker to fall back uniformly when the pressure cooker is controlled to stop pressure relief.
In the embodiment of the present invention, the preset small power may also be determined according to the type of food to be cooked and the cooking effect.
According to an embodiment of the present invention, the preset small power may be less than or equal to half of the first preset power.
According to an embodiment of the present invention, the preset small power is inversely proportional to the amount of food in the pressure cooker.
Specifically, in the process of heating the pressure cooker with high power, whether the pressure cooker needs to be depressurized or not can be judged according to the internal temperature or the internal pressure of the pressure cooker. For example, when the internal temperature of the pressure cooker reaches a first preset temperature (e.g., 110 ℃), or the internal pressure reaches a first preset pressure (e.g., 25kPa), the pressure cooker is controlled to perform a pressure relief action, and at the same time, the pressure cooker is controlled to stop heating or to perform heating with a smaller power (e.g., less than or equal to half of the first preset power), and the larger the amount of food in the pressure cooker, the smaller the preset power is, which can more effectively prevent the food from overflowing and make the food fall back uniformly.
In-process at the pressure release, because the air current upwards strikes and drives rice water and upwards rise, break up the caking between the rice grain, make the thermal field in the whole pressure cooking ware become even, and, because the pressure release in-process does not heat rice water or heat with less power, therefore, when rice water fully overturns, and the hot air flow balance in the pressure cooking ware of not disturbing, therefore after the pressure release action is accomplished, rice water can evenly fall back, and can not appear spilling over the phenomenon because of rice water is too much, thereby make rice water surface level, and then after rice boils thoroughly, can guarantee that rice's surfacing is just pleasing to the eye.
Therefore, according to the heating control method of the pressure cooker provided by the embodiment of the invention, in the pressure relief process of the pressure cooker, the heating process of the pressure cooker is reasonably controlled, for example, heating is stopped or heating is performed with low power, so that when food is fully overturned, the balance of hot airflow in the pressure cooker is not disturbed, and therefore, the food can uniformly fall back when pressure relief is stopped, and the surface of the food is smooth and attractive.
According to an embodiment of the present invention, when the pressure cooker is controlled to release pressure, the method further includes: acquiring current pressure relief time, and judging whether the current pressure relief time is greater than first preset time; and if the current pressure relief time is longer than the first preset time, controlling the pressure cooker to stop pressure relief. The first preset time may be calibrated according to an actual situation, for example, the first preset time may be 0.1s to 30 s.
That is, whether the pressure cooker needs to stop the pressure relief can be judged by the pressure relief time. For example, when the pressure cooker is controlled to start pressure relief, timing is started, and when the timing time reaches a first preset time (for example, 0.2s), the pressure cooker is controlled to stop pressure relief.
It can be understood that, since the internal temperature and the internal pressure of the pressure cooker are reduced during the pressure relief process, in the embodiment of the present invention, whether the pressure relief needs to be stopped may also be determined according to the internal temperature or the internal pressure of the pressure cooker.
According to an embodiment of the present invention, when the pressure cooker is controlled to stop the pressure relief, the method further comprises: acquiring the current pressure relief times, and judging whether the current pressure relief times is greater than a first preset time; if the current pressure relief times is less than or equal to the first preset times, controlling the pressure cooker to work at a second preset power, and continuously judging whether the internal temperature of the pressure cooker is greater than the first preset temperature or whether the internal pressure of the pressure cooker is greater than the first preset pressure; and if the current pressure relief times are larger than the first preset times, judging that the pressure relief process is completely finished, and controlling the pressure cooker to work at a third preset power. The first preset frequency, the second preset power and the third preset power can be calibrated according to actual conditions, and for example, the first preset frequency can be 1-10.
That is to say, in the process that pressure cooker heats, can carry out many times pressure release to guarantee that the food in pressure cooker can tumble many times, thereby make food can be heated by the uniformity.
Specifically, when the internal temperature or the internal pressure of the pressure cooker reaches a preset parameter during the heating of the pressure cooker with high power, the first pressure relief is started, and during the pressure relief, the pressure cooker stops heating or heats with low power. After this pressure release is accomplished, begin to control pressure cooking ware and heat with second preset power (can be less than first preset power), and when pressure cooking ware's internal temperature or internal pressure reached preset parameter once more, begin to carry out the pressure release for the second time, in the pressure release process, pressure cooking ware stops heating or heats with the miniwatt, …, circulate in proper order, until the pressure release number of times reaches first preset number of times (like 5), then no longer carry out the pressure release, begin to heat with third preset power (can be less than first preset power) this moment, end up cooking.
Further, fig. 2 is a flowchart of a heating control method of the pressure cooker according to an embodiment of the present invention. As shown in fig. 2, the heating control method of the pressure cooker may include the steps of:
and S101, starting cooking.
And S102, heating by the pressure cooker at a first preset power P1.
And S103, acquiring the internal temperature or the internal pressure of the pressure cooker in real time.
S104, judging whether the internal temperature is higher than a first preset temperature A1 or whether the internal pressure is higher than a first preset pressure A2. If yes, go to step S105; if not, return to step S102.
And S105, the pressure cooker releases pressure, and stops heating or heats with low power.
And S106, judging whether the current pressure relief time is greater than a first preset time t. If yes, go to step S107; if not, return to step S105.
S107, the pressure cooker stops releasing pressure, the pressure release port is closed, and the pressure cooker continues to start pressing.
And S108, judging whether the pressure relief times are greater than a first preset time C. If yes, go to step S109; if not, step S110 is executed.
And S109, finishing the pressure relief work, and heating the pressure cooker at a third preset power P3.
And S110, heating by the pressure cooker at a second preset power P2.
In summary, according to the heating control method of the pressure cooker in the embodiment of the invention, in the heating process of the pressure cooker, the pressure cooker is controlled to operate at the first preset power, and the internal temperature or the internal pressure of the pressure cooker is obtained in real time. When the internal temperature of the pressure cooker is higher than a first preset temperature or the internal pressure of the pressure cooker is higher than a first preset pressure, the pressure cooker is controlled to start pressure relief, the pressure cooker is controlled to stop heating or to heat with preset low power, and when the pressure cooker is controlled to stop pressure relief, food in the pressure cooker falls back at a constant speed. According to the method, the pressure cooker is controlled to stop heating in the pressure relief process or to heat with low power, so that after the pressure cooker stops pressure relief, food in the pressure cooker can uniformly fall back, and the surface of the food is smooth and attractive.
Fig. 3 is a block schematic diagram of a heating control apparatus of a pressure cooker according to an embodiment of the present invention. As shown in fig. 3, the heating control device of the pressure cooker may include a heating module 10, a pressure relief module 20, a first obtaining module 30, and a control module 40.
Wherein, the first obtaining module 30 is used for obtaining the internal temperature or the internal pressure of the pressure cooker in real time. The control module 40 is connected to the heating module 10, the pressure relief module 20 and the first obtaining module 30, respectively, and the control module 40 is configured to control the heating module 10 to operate at a first preset power in a heating process of the pressure cooker, and determine whether an internal temperature of the pressure cooker is greater than a first preset temperature, or determine whether an internal pressure of the pressure cooker is greater than a first preset pressure. If the internal temperature of the pressure cooker is higher than the first preset temperature or the internal pressure of the pressure cooker is higher than the first preset pressure, the control module 40 controls the pressure relief module 20 to release pressure, and controls the heating module 10 to stop heating or heat with preset low power, so that the food in the pressure cooker uniformly falls back when the pressure relief module 20 is controlled to stop releasing pressure.
In an embodiment of the present invention, the first predetermined temperature may be 101 to 112 ℃ and the first predetermined pressure may be 5 to 50 kPa.
According to an embodiment of the present invention, the preset small power may be less than or equal to half of the first preset power.
According to an embodiment of the present invention, the preset small power is inversely proportional to the amount of food in the pressure cooker.
Specifically, boiled rice is taken as an example. When the control module 40 controls the heating module 10 to heat the rice water, the rice water in the pressure cooker can be rapidly boiled by heating with high power, the internal temperature or the internal pressure of the pressure cooker can be obtained in real time through the first obtaining module 30 in the process of heating the rice water, and whether the pressure cooker needs to be decompressed or not is judged according to the internal temperature or the internal pressure of the pressure cooker. For example, when the internal temperature of the pressure cooker reaches a first preset temperature (e.g., 110 ℃), or the internal pressure reaches a first preset pressure (e.g., 25kPa), the control module 40 controls the pressure relief module 20 to perform the pressure relief action, and at the same time, the control module 40 controls the heating module 10 to stop heating or to heat with a smaller power (e.g., less than or equal to half of the first preset power), and the larger the amount of food in the pressure cooker, the smaller the preset power, which can more effectively prevent the food from overflowing and make the food fall back uniformly.
In the pressure release in-process, because the air current upwards strikes and drives the rice water and upwards rise, break up the caking between the rice grain, make the thermal field in the whole pressure cooking ware become even, and, because the pressure release in-process does not heat the rice water or heat with less power, therefore, when the rice water fully tumbles, and the hot air flow balance in the pressure cooking ware of not disturbing, therefore after the pressure release action is accomplished, the rice water can evenly fall back, and can not appear spilling over the phenomenon because the rice water is too much, thereby make rice water surface level, and then after rice boils thoroughly, can guarantee that the surface of rice levels and is pleasing to the eye.
Therefore, according to the heating control device of the pressure cooker provided by the embodiment of the invention, in the pressure relief process of the pressure cooker, the heating process of the pressure cooker is reasonably controlled, such as stopping heating or heating with low power, so that food can uniformly fall back when the pressure relief of the food is stopped, and the surface of the food is flat and beautiful.
According to an embodiment of the present invention, the control module 40 is further configured to, when controlling the pressure cooker to perform pressure relief, obtain a current pressure relief time, determine whether the current pressure relief time is greater than a first preset time, and control the pressure relief module 20 to stop pressure relief when the current pressure relief time is greater than the first preset time. Wherein, the first preset time can be 0.1 s-30 s.
That is, whether the pressure cooker needs to stop the pressure relief can be judged by the pressure relief time. For example, the control module 40 starts timing when controlling the pressure cooker to start pressure relief, and when the timing time reaches a first preset time (e.g. 0.2s), the control module 40 controls the pressure relief module 20 to stop pressure relief.
It can be understood that, since the internal temperature or the internal pressure of the pressure cooker is reduced during the pressure relief process, in the embodiment of the present invention, whether the pressure relief needs to be stopped may also be determined according to the internal temperature or the internal pressure of the pressure cooker.
According to an embodiment of the present invention, the control module 40 is further configured to, when the pressure relief module 20 is controlled to stop relieving pressure, obtain a current pressure relief frequency, and determine whether the current pressure relief frequency is greater than a first preset frequency, if the current pressure relief frequency is less than or equal to the first preset frequency, the control module 40 controls the heating module 10 to operate at a second preset power, and continuously determine whether the internal temperature of the pressure cooker is greater than the first preset temperature, or determine whether the internal pressure of the pressure cooker is greater than the first preset pressure; if the current pressure relief times is greater than the first preset times, the control module 40 judges that the pressure relief process is completely finished, and controls the heating module 10 to work at a third preset power. Wherein the first preset number of times can be 1-10.
That is to say, in the process that pressure cooker heats, can carry out many times pressure release to guarantee that the food in pressure cooker can tumble many times, thereby make food can be heated by the uniformity.
Specifically, when the control module 40 controls the heating module 10 to heat with high power, when the internal temperature or the internal pressure of the pressure cooker reaches a preset parameter, the first pressure relief is started, and during the pressure relief, the control module 40 controls the heating module 10 to stop heating or to heat with low power. After the pressure relief is completed, the control module 40 controls the heating module 10 to heat with a second preset power (which may be smaller than the first preset power), and when the internal temperature or the internal pressure of the pressure cooker reaches a preset parameter again, the second pressure relief is started to be executed, in the pressure relief process, the control module 40 controls the heating module 10 to stop heating or to heat with a small power, …, the steps are sequentially circulated until the pressure relief frequency reaches the first preset frequency (such as 5 times), the pressure relief is not performed any more, at this time, the control module 40 controls the pressure cooker to start heating with a third preset power (which may be smaller than the first preset power) until the cooking is finished.
According to the heating control device of the pressure cooker, in the heating process of the pressure cooker, the control module controls the heating module to work at the first preset power, judges whether the internal temperature of the pressure cooker is higher than the first preset temperature or not or judges whether the internal pressure of the pressure cooker is higher than the first preset pressure or not, if yes, the control module controls the pressure relief module to start pressure relief, controls the heating module to stop heating or performs heating at a preset low power, and enables food in the pressure cooker to fall back uniformly when the pressure relief module stops pressure relief. The device stops heating at the pressure release in-process through control pressure cooking ware, or heats with less power to after pressure cooking ware stops the pressure release, food among the pressure cooking ware can evenly fall back, make food surface level and pleasing to the eye.
In addition, the embodiment of the invention also provides a pressure cooker which comprises the heating control device of the pressure cooker.
According to the pressure cooker provided by the embodiment of the invention, through the heating control device, the pressure cooker is controlled to stop heating or perform heating with low power in the pressure relief process of the pressure cooker, so that after the pressure cooker stops relieving pressure, food in the pressure cooker can uniformly fall back, and the surface of the food is flat and attractive.
