In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1
The embodiment provides a pressure relief method of an electric pressure cooker, which is suitable for a cooking electric pressure cooker provided with a cooling pressure reduction device and an exhaust pressure reduction device. As shown in figure 1, the pressure relief method of the electric pressure cooker comprises the following steps:
s11, when the electric pressure cooker utilizes the cooling and pressure reducing device to reduce the pressure, the pressure value inside the electric pressure cooker is obtained.
Exemplarily, when the electric pressure cooker finishes cooking, the initial air pressure inside the electric pressure cooker is higher than the ambient atmospheric pressure, and at the moment, the electric pressure cooker needs to be decompressed, and the electric cooker cover can be opened when the internal air pressure is equal to the ambient atmospheric pressure. Because the pressure intensity can reflect the intensity of the pressure intensity born by the unit area, the pressure intensity can reflect the air pressure in the electric pressure cooker. According to an ideal gas state equation: PV ═ nRT, where P is pressure, V is volume, R is a rational gas constant, and n is the amount of gaseous species. According to the ideal gas state equation, when the temperature T in the electric pressure cooker is reduced, the pressure P is also reduced. Because the initial pressure inside the electric pressure cooker is larger, the cooling and pressure reducing device can be firstly adopted to reduce the pressure without opening the exhaust and pressure reducing device, and the pressure reduction is realized by reducing the temperature. When the cooling and pressure reducing device is used for reducing pressure, the pressure value in the electric pressure cooker can be obtained through the pressure sensor arranged in the electric pressure cooker.
And S12, judging whether the pressure value is smaller than a preset threshold value.
For example, the preset threshold is a pressure value at which the electric pressure cooker does not produce an explosion boiling phenomenon, and can be used as a critical pressure value for judging whether an exhaust pressure reducing device of the electric pressure cooker needs to be opened. The preset threshold value can be set according to the rated power or other parameters of the electric pressure cooker, and the preset threshold value is not limited in the application and can be determined by a person skilled in the art according to actual needs.
And S13, when the pressure value is smaller than the preset threshold value, the exhaust pressure reduction device of the electric pressure cooker is started.
Exemplarily, when the pressure sensor detects that the pressure inside the electric pressure cooker is smaller than a preset threshold value, the exhaust pressure reducing device is opened at the moment, so that the phenomenon of bumping cannot be generated in the electric pressure cooker, fluid food is prevented from being ejected from an exhaust port, the exhaust pressure reducing device of the electric pressure cooker is opened at the moment, air injection heat dissipation can be carried out through the exhaust port, and the pressure value in the electric pressure cooker can be quickly reduced by combining with the cooling pressure reducing device, so that the air pressure in the electric pressure cooker is reduced.
According to the pressure relief method of the electric pressure cooker, the relation between the pressure value and the preset threshold value is judged by acquiring the pressure value in the electric pressure cooker, and if the pressure value is not less than the preset threshold value, the pressure is reduced only by the cooling and pressure reducing device; when the pressure value is smaller than the preset threshold value, the exhaust pressure reducing device of the electric pressure cooker is started, so that the exhaust pressure reducing device and the cooling pressure reducing device act together to realize rapid pressure reduction. Compared with the prior art that the cooling and pressure reducing device is used for pressure reduction independently, the pressure reduction method is higher in speed, and the requirement that a user opens the cover as soon as possible after cooking is completed can be met; meanwhile, the method determines the opening time of the exhaust valve according to the internal pressure value, and compared with the method that the exhaust valve is opened for pressure relief after cooking is finished, the method can reduce the working energy consumption of the electric pressure cooker and improve the use safety because the exhaust valve is opened only when the pressure value is smaller than the preset threshold value.
As an alternative embodiment of the present invention, as shown in fig. 2, the pressure relief method of the electric pressure cooker may further include:
and S14, when the pressure value is greater than or equal to the preset threshold value, adjusting the rotating speed of the fan 311 according to the pressure value by using the corresponding relation between the preset pressure value and the rotating speed of the fan.
Illustratively, when the pressure value is greater than or equal to the preset threshold value, the exhaust pressure reduction device is opened at the moment, an explosion boiling phenomenon can be generated in the electric pressure cooker, and fluid food can be sprayed out from the exhaust port, at the moment, in order to avoid the situation, the exhaust pressure reduction device needs to be kept closed, the pressure reduction is carried out only by using the cooling pressure reduction device, the rotating speed of the fan corresponding to the pressure value is determined by detecting the pressure value in the electric pressure cooker, and the air volume is controlled by adjusting the rotating speed of the fan 311 so as to achieve the purpose of reducing the pressure.
As an alternative embodiment of the present invention, in the correspondence relationship between the pressure value and the fan rotation speed in step S14, the fan rotation speed increases as the pressure value decreases.
Illustratively, according to the ideal gas state equation, when the temperature T in the electric pressure cooker is reduced, the pressure P is also reduced, and the heat dissipation can be accelerated by properly increasing the rotating speed of the fan along with the reduction of the pressure value, so that the temperature reduction speed in the electric pressure cooker is increased, the pressure reduction speed in the electric pressure cooker is further increased, and the air pressure in the electric pressure cooker is rapidly reduced.
As an alternative embodiment of the present invention, as shown in fig. 3, the step S14 may include:
and S141, determining a pressure range to which the pressure value belongs.
For example, the pressure value may be obtained from a pressure sensor provided in the electric pressure cooker. When the pressure value is larger than or equal to the preset threshold value, only the cooling pressure reduction device needs to be started at the moment, the cooling pressure reduction device determines the pressure range according to the obtained pressure value in the electric pressure cooker, the pressure value in the electric pressure cooker can be divided into a plurality of ranges at the moment, and after the pressure value in the electric pressure cooker is obtained, the pressure range to which the pressure value belongs is determined at first. For example, the pressure value in the electric pressure cooker is divided into three ranges (P4, P3), (P3, P2), and (P2, P1), and according to that the pressure value obtained by the pressure sensor arranged in the electric pressure cooker is P, it is necessary to determine which pressure range the pressure value P belongs to at this time.
And S142, determining the rotating speed of the fan 311 according to the pressure range.
Illustratively, the rotation speed of the blower 311 is adjusted to a corresponding value according to the determined pressure range to ensure that the pressure in the electric pressure cooker decreases as the temperature decreases. For example, the pressure value in the electric pressure cooker is divided into three ranges (P4, P3), (P3, P2), (P2, P1). When the pressure value P is at (P2, P1), adjusting the fan rotation speed to N1; when the pressure value P is at (P3, P2), adjusting the fan rotation speed to N2; when the pressure value P is at (P4, P3), the fan speed is adjusted to N3.
The pressure in the electric pressure cooker is segmented, the rotating speed of the fan is adjusted according to the pressure value in the electric pressure cooker, and the pressure relief control method of the pressure segmentation is adopted, so that the electric pressure cooker can realize rapid pressure relief.
Specifically, the pressure value in the electric pressure cooker is divided into four ranges (0, P4), (P4, P3), (P3, P2), (P2, P1), and the pressure value P4 is used as a preset threshold. When the pressure value P in the electric pressure cooker is greater than or equal to P4, only starting the cooling and pressure reducing device to reduce the pressure; when the pressure value P in the electric pressure cooker is smaller than P4, the exhaust pressure reducing device of the electric pressure cooker is turned on again, the rotating speed of the fan 311 is adjusted, and the cooling pressure reducing device and the exhaust pressure reducing device act simultaneously to perform pressure relief, as shown in fig. 4. When the pressure value P in the electric pressure cooker is greater than or equal to P4 and only the cooling and pressure reducing device is started to reduce the pressure, the pressure range in which the pressure value P in the current electric pressure cooker is located is determined, and the corresponding fan rotating speed is determined according to the determined pressure range. The pressure in the electric pressure cooker is segmented, the rotating speed of the fan 311 is adjusted according to the pressure value in the electric pressure cooker, segmented pressure relief control is adopted, and meanwhile, the opening and closing of the exhaust and pressure reduction device are controlled, so that the electric pressure cooker can realize rapid pressure relief.
As shown in fig. 5, when the pressure value P is at (P2, P1), the fan rotation speed is adjusted to N1; when the pressure value P is at (P3, P2), adjusting the fan rotation speed to N2; when the pressure value P is at (P4, P3), adjusting the fan rotation speed to N3; when the pressure in the electric pressure cooker is at (0, P4), the rotating speed of the fan is adjusted to N0. For example, P1-100 kPa, P2-70 kPa, P3-40 kPa, and P4-10 kPa. When the pressure value P is (P2, P1), the exhaust pressure reduction device is closed, the cooling pressure reduction device is opened, and the rotating speed of the fan is adjusted to be N1 equal to 2000 rpm; when the pressure value P is (P3, P2), the exhaust pressure reducing device is turned off, the cooling pressure reducing device is turned on, and the rotation speed of the fan 311 is adjusted to N2-2500 rpm; when the pressure value P is (P4, P3), the exhaust pressure reduction device is still closed, the cooling pressure reduction device is opened, and the rotating speed of the fan is adjusted to N3 which is 3000 rpm; when the pressure value P is less than 10kPa, the exhaust pressure reduction device is opened again, and at this time, the rotation speed of the fan 311 may be adjusted to N0 ═ 2000rpm, where N0 of the fan 311 may be, but is not limited to, N1.
