[0058] In a specific embodiment, the opening and closing of the gas delivery device 21 and the first regulating valve 23 can be controlled according to the temperature of the gas in the pot body 11 detected by the temperature detection device. In actual application, after cooking is completed, the gas delivery device 21 and the first regulating valve 23 are controlled to be in an open state so that the gas delivery device 21 can transmit gas of a preset temperature to the interior of the pot 11 through the first cooling gas path 22. When the temperature detection device detects that the temperature of the gas in the pot body 11 is the first preset temperature value, the gas delivery device 21 and the first regulating valve 23 are closed to terminate the cooling process. The cooling process can then be accurately controlled according to the detected temperature value to reduce energy consumption.

[0059] It should be noted that the first preset temperature value is a temperature value at which the cover 12 can be opened.

[0060] In another specific embodiment, the opening and closing of the third regulating valve 43 and the gas cooling device 44 can be controlled according to the temperature of the gas in the pot body 11 detected by the temperature detection device.

During the cooling process, the temperature of the gas in the pot body 11 is detected. When it is detected that the temperature of the gas in the pot body 11 is a second preset temperature value, the air induction cooling method is started, that is, the gas delivery device 21 and the first regulating valve 23 are controlled to be in an open state, so that the gas delivery device 21 transmits gas of a preset temperature to the interior of the pot 11 through the first cooling gas path 22. When the temperature detection device detects that the temperature of the gas in the pot body 11 is the first preset temperature value, the gas delivery device 21 and the first regulating valve 23 are closed to terminate the cooling process, so as to further reduce energy consumption while improving the cooling efficiency.

[0063] It should be noted that when the air cooling method is started to cool the temperature, the liquid delivery device 31 and the second regulating valve 33 are controlled to be in a disconnected state so as to stop cooling the outer surface of the pot body 11.

[0064] It should be noted that the second preset temperature value is greater than the first preset temperature value. Specifically, the difference between the second preset temperature value and the first preset temperature value is greater than or equal to the first temperature threshold. The first temperature threshold can be set according to actual conditions and is not specifically limited here.

[0065] In another specific embodiment, the interior of the pot 11 can be cooled by combining a gas self-circulation cooling method in which the high-temperature and high-pressure gas in the pot body 11 is circulated and cooled through the second cooling gas circuit 4 and the gas cooling device 44, and a liquid circulation cooling method in which the liquid conveying device 31 cools the outer surface of the pot body 11 through the cooling water circuit 32, so as to improve the cooling efficiency and reduce energy consumption.

[0066] In actual application, after cooking is finished, the liquid conveying device 31 and the second regulating valve 33 are controlled to be in an open state, so that the liquid conveying device 31 outputs liquid of a preset temperature to cool the outer surface of the pot body 11. During the cooling process, the temperature of the gas in the pot body 11 is detected.

When the temperature detection device detects that the temperature of the gas in the pot body 11 is a first preset temperature value, the third regulating valve 43 and the gas cooling device 44 are closed to terminate the cooling process, so as to further reduce energy consumption while improving the cooling efficiency.

[0067] It should be noted that when the gas self-circulation cooling method is started for cooling, the liquid delivery device 31 and the second regulating valve 33 are controlled to be in a closed state so as to stop cooling the outer surface of the pot body 11.

[0068] It should be noted that the third preset temperature value is greater than the first preset temperature value. Specifically, the difference between the third preset temperature value and the first preset temperature value is greater than or equal to the second temperature threshold, wherein the second temperature threshold can be set according to actual conditions and is not specifically limited here.

[0069] In another specific embodiment, the interior of the pot 11 can be cooled by combining the air entrainment cooling method in which the gas delivery device 21 transmits the gas of preset temperature to the interior of the pot 11 through the first cooling gas path 22, and the gas self-circulation cooling method in which the high-temperature and high-pressure gas in the pot body 11 is circulated and cooled through the second cooling gas path 4 and the gas cooling device 44, so as to improve the cooling efficiency and reduce energy consumption.

[0070] In actual application, after cooking is finished, the gas self-circulation cooling mode is started, that is, the third regulating valve 43 and the gas cooling device 44 are controlled to be in the open state, so that the high-temperature and high-pressure gas in the pot body 11 can be circulated and cooled with the help of the second cooling gas path 4 and the gas cooling device 44. During the cooling process, the temperature of the gas in the pot body 11 is detected. When it is detected that the temperature of the gas in the pot body 11 is a fourth preset temperature value, the air bleed cooling mode is started, that is, the gas delivery device 21 and the first regulating valve 23 are controlled to be in the open state, so that the gas delivery device 21 transmits the preset temperature gas to the inside of the pot 11 through the first cooling gas path 22. When the temperature detection device detects that the temperature of the gas in the pot body 11 is the first preset temperature value, the gas delivery device 21 and the first regulating valve 23 are closed to terminate the cooling process, so as to further reduce energy consumption while improving the cooling efficiency.

[0071] It should be noted that when the bleed air cooling method is started for cooling, the gas self-circulation cooling method can be turned off for cooling, or the gas self-circulation cooling method can be kept on for cooling. Preferably, when the bleed air cooling method is started for cooling, the gas self-circulation cooling method is turned off for cooling, so as to further reduce energy consumption while improving the cooling efficiency.

[0072] It should be noted that the fourth preset temperature value is greater than the first preset temperature value. Specifically, the difference between the fourth preset temperature value and the first preset temperature value is greater than or equal to the third temperature threshold. The third temperature threshold can be set according to actual conditions and is not specifically limited here.

[0073] In another specific embodiment, the interior of the pot 11 can be cooled by combining the air entrainment cooling method in which the gas delivery device 21 transmits the gas of a preset temperature to the interior of the pot 11 through the first cooling gas path 22, and the gas self-circulation cooling method in which the high-temperature and high-pressure gas in the pot body 11 is circulated and cooled through the second cooling gas path 4 and the gas cooling device 44.

[0074] In actual application, after cooking is finished, the liquid delivery device 31 and the second regulating valve 33 are both controlled to be in an open state, so that the liquid delivery device 31 outputs liquid of a preset temperature to cool the outer surface of the pot body 11. During the cooling process, the temperature of the gas in the pot body 11 is detected. When the temperature of the gas in the pot body 11 is detected to be a fifth preset temperature value, the gas self-circulation cooling mode is started, that is, the third regulating valve 43 and the gas cooling device 44 are both controlled to be in an open state, so that the gas in the pot body 11 is cooled by the second cooling gas path 4 and the gas cooling device 44.

When the temperature detection device detects that the temperature of the gas in the pot body 11 is the first preset temperature value, the gas delivery device 21 and the first regulating valve 23 are closed to terminate the cooling process, so as to further reduce energy consumption while improving the cooling efficiency.

[0075] It should be noted that when the gas self-circulation cooling method is started for cooling, the liquid delivery device 31 and the second regulating valve 33 are controlled to be in a closed state so as to stop cooling the outer surface of the pot body 11. When the air induced cooling method is started for cooling, the gas self-circulation cooling method can be closed for cooling, or the gas self-circulation cooling method can be kept open for cooling. Preferably, when the air induced cooling method is started for cooling, the gas self-circulation cooling method is closed for cooling, so as to further reduce energy consumption while improving the cooling efficiency.

[0076] It should be noted that the fifth preset temperature value is greater than the sixth preset temperature value, and the sixth preset temperature value is greater than the first preset temperature value. Specifically, the difference between the fifth preset temperature value and the sixth preset temperature value is greater than or equal to the fourth temperature threshold, and the difference between the sixth preset temperature value and the first preset temperature value is greater than or equal to the fifth temperature threshold. The fourth temperature threshold and the fifth temperature threshold can be set according to actual conditions and are not specifically limited here.
