At this time, the gas is continued to be filled into the wok 100, and the wok 100 The internal air pressure is greater than the pressure of the liquid fluid in the pressure stabilizing device connected to the smoke exhaust port 207 of the pot cover 200. When a pressure difference is generated between the air pressure in the wok 100 and the pressure of the liquid fluid, the gas in the wok 100 passes through the liquid fluid. and then discharged, so that the air pressure in the wok 100 is not only maintained at a constant pressure value, but also the air in the wok 100 is in a continuous flow state. This cooking state not only allows the ingredients in the pot 100 to mature quickly, but also does not cause damage due to the air flow. The ingredients are in a simmering state.

Specifically, as shown in FIGS. 1 and 2 , the pressure wok device includes a wok 100 , a pot lid 200 , a pressure charging tube 13 , a gas charging device 10 , a pressure stabilizing device and a sealed cooking cavity 300 .

1. Wok 100, pot lid 200 and pressure tube 13

As shown in FIGS. 3 and 4 , the pot cover 200 includes an upper fixed plate 201 and a lower fixed plate 202 that are fixedly connected to each other, and is rotatably clamped between the upper fixed plate 201 and the lower fixed plate 202 . The rotating plate 203 can be detachably connected to the rotating plate 203 with the pot lid bladder assembly 204 and the elastic device 205.

The elastic device 205 is disposed on the inside of the rotating plate 203 and elastically resists the outside of the pot lid assembly 204. The pot lid assembly 204 is sealed and pressed on the wok 100 under the action of the elastic device 205. On the mouth of the pot, when the wok 100 rotates, the pot lid assembly 204 and the wok 100 can generate sufficient friction force to rotate synchronously.

The upper fixed plate 201 and the lower fixed plate 202 are both fixed to the inner shell 301 of the cooking machine through fasteners. The pot lid 200 is provided with an air filling port 206 and a smoke exhaust port 207.

The air outlet 111 of the diaphragm pump 11 is also connected to the charging pipe 13 and is connected to the charging pipe 13. The air filling port 206 of the pot cover 200 is connected.

A one-way valve 14 is provided at the exhaust port 121 of the high-speed centrifugal fan 12 to prevent the gas in the wok 100 from flowing back from the charging pipe 13 to the high-speed centrifugal fan 12 when the air pressure in the wok 100 is too high.

The high-speed centrifugal fan 12 and the diaphragm pump 11 are both connected to the controller of the cooking machine, and both are in independent control working modes. The specific working modes are as follows:

During the cooking process, when the pressure sensor installed in the wok 100 detects that the air pressure in the wok 100 is less than the set air pressure, the controller controls to turn on the high-speed centrifugal fan 12 to quickly fill the wok 100 with gas. At this time, the diaphragm The pump 11 is in a closed state. When it is detected that the air pressure in the frying pan 100 is equal to the set air pressure, the controller controls the high-speed centrifugal fan 12 to stop working, and at the same time, the diaphragm pump 11 is turned on, and the air intake volume is lower than that of the high-speed centrifugal fan 12. The gas in the wok 100 continues to be filled. At this time, the air pressure in the wok 100 is higher than the pressure of the liquid fluid in the pressure stabilizing device. The gas in the wok 100 passes through the liquid fluid and is discharged. When the gas filling and the discharged gas reach a balanced state, The air pressure in the wok 100 is always maintained at a constant pressure during the cooking process when the pot body 100 and the pot lid 200 are tightly coupled.

Then continue to fill the wok 100 with gas through the diaphragm pump 11 at a low speed, so that the gas in the wok 100 is replaced without causing the heat in the wok 100 to be taken away, ensuring that the gas in the wok 100 is always maintained at high pressure while being replaced. Cooking can be done in a state that reduces power consumption and costs.

The set air pressure can be set to different values according to the cooking requirements of different dishes. Preferably, the set air pressure range in the present invention is 5KPa-8KPa higher than a standard atmospheric pressure.

3. Voltage stabilizing device

The pressure stabilizing device is an oil fume filtering device 400 filled with liquid fluid at a set height that is harmless to the human body, and can stabilize the air pressure in the wok 100 .

The present invention uses the oil fume filter device 400 filled with liquid fluid as a pressure stabilizing device to relieve the pressure of the wok 100 while maintaining the air pressure in the wok 100 at a constant value. Compared with the mechanical valve switch or the electronically controlled valve switch, it has the following advantages: It has the advantages of safety, reliability, long service life and low cost.

Specifically, as shown in FIGS. 5 and 6 , the oil fume filtering device 400 includes a cavity 41 containing the liquid fluid, a secondary filtering device 42 and an exhaust fan 43 arranged outside the cavity 41 .

3.1 Cavity 41

The cavity 41 is provided with an air inlet 4121 and an air outlet 4111. The air inlet 4121 is connected to the smoke exhaust port 207 of the pot cover 200 through the gas pipe 21. The air outlet 4111 of the cavity 41 passes through the exhaust pipe. 44 is connected to the exhaust fan 43.

The interior of the cavity 41 is divided into a relatively closed left chamber 411 and a right chamber 412. The bottoms of the left chamber 411 and the right chamber 412 are connected.

Specifically, the cavity 41 in the present invention has a rectangular parallelepiped structure. The interior of the cavity 41 is divided into a left chamber 411 and a right chamber 412 through a partition 414, and there is a spacer at the bottom of the partition 414. For the communication hole 413 connecting the left chamber 411 and the right chamber 412, the air inlet 4121 is provided at the upper part of the right chamber 41, and the air outlet 4111 is provided at the upper part of the left chamber 411. Under normal pressure, the liquid The height of the fluid in the left chamber 411 and the right chamber 412 is equal and located below the air inlet 4121 and the air outlet 4111 .

The liquid fluid is water, or a layered combination composed of water and edible oil. When the liquid fluid is a layered combination of water and edible oil, when considering the pressure of the liquid fluid on the bottom of the cavity 41, depending on the density of the edible oil (the density of edible oil is generally between 0.91-0.925) Approximately to water (that is, the pressure of a liquid fluid is determined only by the height of the liquid fluid).

Filtration principle: Water can capture some hydrophilic substances in gas molecules, such as gas molecules in water-based liquid seasonings, while oil can capture some lipophilic substances in gas molecules, such as oil smoke molecules. Compared with the filter device using flexible filter media, the advantages of this structure are: low material cost, high filtration efficiency, and no problem that the flexible filter media will be affected by the filter quality (referring to the substances to be filtered, such as solid particles, oil, etc.) Drops, etc.) blockage resulting in poor airflow. When the liquid filtrate has a high concentration of filtrate, it can be discharged through the sewer pipe.

Note: Flexible filter media has the following categories:

Metal filter media.

Metal and non-metal mixed media.

The height of the liquid fluid is set according to the set air pressure. For the same type of liquid fluid in the same cavity 41, the bottom area of the cavity 41 is the same, and the density of the liquid fluid is the same. Therefore, the liquid fluid has the same impact on the cavity. The pressure at the bottom of the body 41 is only related to the height of the liquid fluid. The present invention adjusts the air pressure in the wok 100 by adjusting the height of the liquid fluid so that the pressure of the liquid fluid on the bottom of the cavity 41 is equal to the set air pressure, so that it can be pressurized during cooking. The air pressure is always maintained at a constant level during the cooking process.

A drain port 416 is provided at the bottom of the cavity 41 and a water inlet 417 is provided at the top of the cavity 41. When the intelligent cooking machine executes the cooking recipe program, the controller receives the set air pressure value and controls the drain port 416 and the water inlet respectively. The drain valve and the water inlet valve at 417 are opened and closed to adjust the height of the liquid fluid in the cavity, so that the air pressure in the wok 100 can be stabilized at the set air pressure value during the cooking process.

The cavity of the present invention not only serves as a pressure stabilizing device, but also can filter the gas (oil fume gas) discharged from the wok 100.

Furthermore, in order to increase the contact time between the gas and the liquid fluid in the left chamber 411 (that is, to increase the filter channel) and to improve the effect of oil fume filtration, several transverse partitions are spaced from bottom to top in the left chamber 411. plate 415, each transverse partition 415 is provided with a notch 4151, and the notches 4151 on two adjacent transverse partitions 415 are offset in the horizontal direction, from the bottom of the left chamber 411 (i.e., the communication hole) to the outlet A gas filter channel with an "S" shape is formed between the air holes 4111.

Specifically, the notch 4151 is composed of a number of small holes arranged in a matrix. Several small holes are arranged to form the notch 4151, which can disperse the bubbles when the gas passes through the small holes, which is beneficial to increasing the amount of oil smoke gas and liquid fluid. The contact area improves processing efficiency.
