[0031] In the embodiments of the present application, Figure 1 and Figure 2 As shown, the first energy conversion device 21 is arranged toward the exhaust port 14 to fully utilize the exhaust energy. The airflow formed by the pressure cooking component when exhausting can drive the first energy conversion device 21 to rotate, so that the exhaust energy is converted into the mechanical energy of the first energy conversion device 21, thereby realizing energy conversion. The second energy conversion device 22 is arranged close to the box-type shell 11, and the first energy conversion device 21 is connected to the second energy conversion device 22, so that the mechanical energy of the first energy conversion device 21 is transmitted to the second energy conversion device 22, and then the second energy conversion device 22 is further converted into electrical energy and stored, so as to realize the reuse of exhaust gas.

[0032] In an optional embodiment, the first energy conversion device 21 includes a rotating shaft and a plurality of rotating parts arranged on the rotating shaft, one end of the rotating shaft is connected to the rotating part, and the other end of the rotating shaft is connected to the second energy conversion device 22, and the airflow can drive the rotating part to rotate, thereby driving the rotating shaft to rotate.

The rotor unit can rotate in the preset space. The rotor unit includes a rotating shaft and a metal coil arranged on the rotating shaft. The metal coil constitutes a closed loop. When the rotating shaft rotates in the preset space, the metal coil on the rotating shaft cuts the magnetic flux lines, thereby generating an induced electromotive force, thereby converting mechanical energy into electrical energy.

[0043] In a specific embodiment, one end of the rotating shaft is fixedly connected to the rotating shaft body, and the rotating shaft body can drive the rotating shaft to rotate, so that the mechanical energy of the rotating shaft body is converted into the mechanical energy of the rotating shaft, and then the metal coil on the rotating shaft cuts the magnetic flux lines, thereby generating an induced potential, which is led out through the wiring ports at both ends of the metal coil, thereby generating current, thereby realizing energy conversion.

[0049] In the embodiment of the present application, the wind speed detection device 24 can be a wind speed sensor. By setting the wind speed detection device 24, the start and stop of the refrigeration component 15 used to cool the pressure cooking component can be accurately controlled according to the exhaust speed at the exhaust port 14 detected by the wind speed detection device 24, thereby reducing energy consumption.

[0050] In practical applications, the wind speed detection device 24 is disposed directly above the exhaust port 14 so as to accurately obtain the exhaust speed at the exhaust port 14 , thereby improving the accuracy of controlling the refrigeration component 15 .

At the same time, since the change of the exhaust speed at the exhaust port 14 is significantly faster than the change of the temperature in the pot, the signal corresponding to the exhaust speed can be responded to quickly. Therefore, the control component 3 controls the start and stop of the refrigeration component 15 according to the exhaust speed, making the entire control process faster and more stable and effective, thereby avoiding the defects of slow response and large error of controlling the refrigeration component 15 by only relying on detecting the temperature in the pot.

The rotation speed and / or the exhaust speed of the fan blades and the working time of the liquid conveying device to output the coolant are all affected by the exhaust speed, and then, the exhaust speed detected by the wind speed detection device 24 can be linked to the rotation speed of the fan blades in the air-cooling component and / or the working time of the liquid conveying device to output the coolant, so as to accurately and efficiently control the operating speeds of the air-cooling component and the water-cooling component in the refrigeration assembly 15.

[0063] Based on the technical features of the exhaust gas utilization device of the above-mentioned box-type pressure cooking device, the working principle of the exhaust gas utilization device is described below.

[0064] In a specific embodiment, after cooking is completed, the exhaust port 14 is opened so that the high-temperature and high-pressure gas in the pot body 12 of the pressure cooking component can be exhausted by the exhaust port 14. Then, the airflow formed by the pressure cooking component during exhaust drives the rotating part in the first energy conversion device 21 to rotate. Since one end of the rotating shaft in the first energy conversion device 21 is fixedly connected to the rotating part, at this time, the rotating part rotates synchronously with the rotating shaft, thereby converting the airflow formed by the pressure cooking component during exhaust into mechanical energy of the first energy conversion device 21.

Specifically, when the wind speed detection device 24 detects that the exhaust speed is greater than or equal to the third preset wind speed and less than the fourth preset wind speed, the control component 3 controls the rotation speed of the fan blades in the air-cooled component to be the first preset speed, or controls the working time of the liquid delivery device in the water-cooled component to output the coolant to be the first preset time, or controls the rotation speed of the fan blades in the air-cooled component to be the second preset speed and controls the working time of the liquid delivery device in the water-cooled component to be the second preset time. Furthermore, when the wind When the speed detection device 24 detects that the exhaust speed is greater than or equal to the fifth preset wind speed and less than the sixth preset wind speed, the control component 3 controls the rotation speed of the fan blades in the air-cooled component to be the third preset speed, or controls the working time of the liquid conveying device in the water-cooled component to output the coolant to be the third preset time, or controls the rotation speed of the fan blades in the air-cooled component to be the fourth preset speed and controls the working time of the liquid conveying device in the water-cooled component to be the fourth preset time, and so on.
