[0040] Please refer to Figure 1 , Figure 2 and Figure 3A cooking device 100 according to an embodiment of the utility model includes a pot cover assembly 10, a pot body 24 and a sealing assembly 28. The pot cover assembly 10 includes a pot cover 11 and an exhaust device 16. The pot cover 11 is provided with a first exhaust hole 12 and a second exhaust hole 14. The exhaust device 16 is connected to the pot cover 11 and seals the first exhaust hole 12. The pot body 24 is connected to the pot cover 11. A cooking cavity 26 is formed in the pot body 24. The pot cover 11 covers the cooking cavity 26. The sealing assembly 28 includes a movable first sealing member. The first sealing member 30 is used to open and close the second exhaust hole 14, and the exhaust area of the second exhaust hole 14 is larger than the exhaust area of the first exhaust hole 12. When the second exhaust hole 14 is opened, the cooking cavity 26 is connected to the outside of the cooking cavity 26 through the second exhaust hole 14.
[0041] In the above-mentioned cooking device 100, by adding a second exhaust hole 14 on the pot cover 11, the exhaust area of the second exhaust hole 14 is larger than the exhaust area of the first exhaust hole 12. When the cooking device 100 needs to perform pressureless cooking, the first sealing member 30 can open the second exhaust hole 14, and the cooking cavity 26 is connected to the outside of the cooking cavity 26 through the second exhaust hole 14, thereby increasing the exhaust volume, which to a certain extent avoids the decrease in cooking speed and the increase in cooking time caused by insufficient exhaust volume of the exhaust device 16.
[0042] Specifically, in Figure 1 In the illustrated embodiment, the cooking device 100 may include a pressure cooker. The cooking device 100 may have a pressure cooking function and a pressure-free cooking function. The pot cover assembly 10 may be disposed above the pot body 24. The height direction of the cooking device 100 may be represented by H. Optionally, along the H direction, a first exhaust hole 12 and a second exhaust hole 14 may be provided on the pot cover 11. The first exhaust hole 12 and the second exhaust hole 14 may be provided at different positions on the pot cover 11. The exhaust device 16 may be connected to the pot cover 11 and may seal the first exhaust hole 12. A cooking cavity 26 may be formed in the pot body 24. The pot body 24 may be connected to the pot cover 11, and the pot cover 11 may cover the cooking cavity 26, so that food may be placed in the cooking cavity 26 for cooking.
[0043] exist Figure 3 In the illustrated embodiment, the sealing assembly 28 is installed on the side of the pot cover 11 away from the cooking cavity 26. At this time, the first sealing member 30 closes the second exhaust hole 14, so that the cooking cavity 26 cannot be connected to the outside of the cooking cavity 26 through the second exhaust hole, thereby sealing the cooking cavity 26.
[0044] exist Figure 1In the illustrated embodiment, the sealing assembly 28 is mounted on the side of the pot cover 11 close to the cooking cavity 26, and the first sealing member 30 closes the second exhaust hole 14, so that the cooking cavity 26 cannot communicate with the outside of the cooking cavity 26 through the second exhaust hole 14, and the sealing assembly 28 can seal the cooking cavity 26. That is, by adding the second exhaust hole 14 to the pot cover 11, the exhaust area of the second exhaust hole 14 is larger than the exhaust area of the first exhaust hole 12, so that the airflow discharge amount (loss amount) generated by the cooking device 100 during the pressureless cooking process is greater than the airflow generation amount, so that the cooking device 100 can smoothly perform pressureless cooking. Therefore, when the cooking device 100 needs to perform pressureless cooking, the first sealing member 30 can open the second exhaust hole 14, so that the cooking cavity 26 communicates with the outside of the cooking cavity 26 through the second exhaust hole 14, and then the exhaust amount can be increased, which to a certain extent avoids the decrease in cooking speed and the increase in cooking time due to insufficient exhaust amount of the exhaust device 16.
[0045] It should be noted that, in one embodiment, when the exhaust device 16 seals the first exhaust hole 12 and the first seal 30 closes the second exhaust hole 14, the cooking device 100 can perform pressure cooking. In one embodiment, when the first seal 30 opens the second exhaust hole 14, the cooking cavity 26 can communicate with the outside of the cooking cavity 26 through the second exhaust hole 14, and the cooking device 100 can perform non-pressure cooking.
[0046] Optionally, when the first sealing member 30 opens the second exhaust hole 14, the exhaust device 16 may also open the first exhaust hole 12. The cooking cavity 26 may be exhausted through the first exhaust hole 12 and the second exhaust hole 14, further increasing the exhaust speed.
[0047] Please combine Figure 1 In some embodiments, the exhaust device 16 includes an exhaust valve 18 , and the exhaust valve 18 is movably disposed on the pot cover 11 .
[0048] In this way, the cooking apparatus 100 can release pressure through the exhaust device 16 during pressurized cooking.
[0049] Specifically, optionally, the exhaust device 16 may include an exhaust member 20 and an air inlet member 22. The exhaust valve 18 may be arranged near the top of the pot cover 11. The exhaust member 20 may be arranged between the exhaust valve 18 and the air inlet member 22. The exhaust member 20 may pass through the pot cover 11. One end of the exhaust member 20 passing through the pot cover 11 near the cooking cavity 26 may be threadedly connected to the air inlet member 22. The first exhaust hole 12 may pass through the exhaust member 20 and the air inlet member 22, and may be located in the middle of the exhaust member 20 and the air inlet member 22.
[0050] Optionally, the exhaust valve 18 may be a pressure limiting valve, which may open when the pressure in the cooking cavity 26 is greater than a pressure limiting threshold of the pressure limiting valve, thereby ensuring the safety of the cooking device 100 to a certain extent. In one example, the pressure limiting threshold of the pressure limiting valve is 70 kPa (kilopascals).
[0051] In one embodiment, when the cooking device 100 performs pressurized cooking, initially, the pressure limiting valve can seal the first exhaust hole 12 under the action of gravity. The gas generated in the cooking cavity 26 enters the first exhaust hole 12 through the air inlet 22, but cannot be discharged from the first exhaust hole 12. As cooking proceeds, when the air pressure in the cooking cavity 26 is greater than the pressure limiting threshold of the pressure limiting valve, the air pressure in the first exhaust hole 12 can lift the pressure limiting valve, and then the gas in the cooking cavity 26 can be discharged through the first exhaust hole 12, achieving a short-term pressure relief effect, and to a certain extent ensuring the safety of the cooking device 100. When the air pressure in the cooking cavity 26 is lower than the pressure limiting threshold of the pressure limiting valve, the pressure limiting valve reseals the first exhaust hole 12.
[0052] It should be noted that the cooking device 100 may be provided with an exhaust drive mechanism (not shown) near the exhaust valve 18. The exhaust drive mechanism may control the exhaust valve 18 to release pressure and exhaust when the air pressure in the cooking cavity 26 reaches a predetermined pressure, so that the air pressure in the cooking cavity 26 is less than the predetermined pressure, and the exhaust drive mechanism may drive the exhaust valve 18 to seal the first exhaust hole 12. In one example, when the cooking device 100 performs pressurized cooking, the exhaust valve 18 may reciprocate at one end of the first exhaust hole 12 away from the cooking cavity 26. The predetermined pressure is less than the pressure limit threshold of the exhaust valve 18. In one example, the predetermined pressure is 50 kPa, and the pressure limit pressure of the exhaust valve 18 is 70 kPa.
[0053] In some embodiments, the exhaust area of the second exhaust hole 14 is greater than or equal to 30 mm^2 (square millimeters).
[0054] In this way, it can be ensured that the exhaust area of the second exhaust hole 14 meets the relevant exhaust speed design to a certain extent.
[0055] Specifically, in one embodiment, the second vent hole 14 is a cylindrical hole, and the venting area of the cylindrical hole is the area of the bottom surface of the cylinder. In one embodiment, the second vent hole 14 is a prismatic hole, and the venting area of the prismatic hole is the area of the bottom surface of the prism. The bottom surface of the prism includes but is not limited to a triangle, a quadrilateral, a pentagon or other polygons. The prism may include a straight prism and an oblique prism.
[0056] Optionally, for other regular or irregular shaped second exhaust holes 14, the exhaust area of the second exhaust hole 14 may be the area of a plane shape obtained by a cross section perpendicular to the axis of the second exhaust hole 14. When there are multiple areas of the obtained plane shapes, the minimum area of the plane shapes is greater than or equal to 30 mm^2.
[0057] The exhaust area of the second exhaust hole 14 is S2, and the exhaust area of the second exhaust hole 14 is greater than or equal to 30 mm^2, that is, S2≥30 mm^2. In some examples, S2=30 mm^2, 35 mm^2, 40 mm^2, 45 mm^2, 50 mm^2 or other values ≥30 mm^2. The upper limit of S2 can be determined according to the spatial configuration of the pot cover 11 and the size of the cooking device 100, and the utility model does not limit this.
[0058] In some embodiments, the exhaust area of the first exhaust hole is less than or equal to 10 mm^2.
[0059] In this way, the cooking device 100 can smoothly perform pressure cooking to a certain extent.
[0060] Specifically, in one embodiment, the first vent hole 12 is a cylindrical hole, and the venting area of the cylindrical hole is the area of the bottom surface of the cylinder. In one embodiment, the first vent hole 12 is a prismatic hole, and the venting area of the prismatic hole is the area of the bottom surface of the prism. The bottom surface of the prism includes but is not limited to a triangle, a quadrilateral, a pentagon or other polygons. The prism may include a straight prism and an oblique prism.
[0061] Optionally, for other regular or irregular shaped first exhaust holes 12, the exhaust area of the first exhaust hole 12 may be the area of a plane shape obtained by a cross section perpendicular to the axis of the first exhaust hole 12. When there are multiple areas of the obtained plane shapes, the maximum area of the plane shapes is less than or equal to 10 mm^2.
[0062] The exhaust area of the first exhaust hole 12 is S1, and the exhaust area of the first exhaust hole 12 is less than or equal to 10 mm^2, that is, S1≤10 mm^2. In some examples, S1=10 mm^2, 8 mm^2, 6 mm^2, 5 mm^2 or other values ≤10 mm^2. The lower limit of S1 can be determined according to the spatial configuration of the pot cover 11, the size of the cooking device 100, and the difficulty of processing, and the utility model does not limit this.
[0063] The exhaust area of the first exhaust hole 12 is less than or equal to 10 mm^2, which can, to a certain extent, ensure that when the exhaust valve 18 releases pressure, the exhaust amount (loss amount) of airflow is less than the generation amount of airflow, thereby ensuring that after the exhaust valve 18 releases pressure, the cooking device 100 can still perform pressurized cooking smoothly.
[0064] Please combine Figure 1 In some embodiments, the sealing assembly 28 is detachably connected to the pot cover 11.
[0065] Therefore, the second exhaust hole 14 can be opened by removing the sealing assembly 28 .
[0066] Specifically, in Figure 3 In the illustrated embodiment, the sealing assembly 28 is detachably mounted on a side of the pot cover 11 away from the cooking cavity 26 , and at this time, the first sealing member 30 closes the second exhaust hole 14 .
[0067] exist Figure 1 In the illustrated embodiment, the sealing assembly 28 is detachably mounted on a side of the pot cover 11 close to the cooking cavity 26 , and the first sealing member 30 closes the second exhaust hole 14 .
[0068] When the second exhaust hole 14 needs to be opened for pressure-free cooking, the sealing assembly 28 can be removed from the pot cover 11 to open the second exhaust hole 14 , and the cooking cavity 26 can be connected to the outside of the cooking cavity 26 through the second exhaust hole 14 .

[0070] In this way, the sealing assembly 28 can be fixedly connected to the pot cover 11 .
[0071] Specifically, in Figure 1 In the embodiment, the sealing assembly 28 can be detachably connected to the pot cover 11 by means of a buckle, so that the sealing assembly 28 can be fixedly connected to the pot cover 11. It should be noted that the buckle method can be a matching method of a buckle column and a buckle hole, or a matching method of a buckle and a clamping ring, or other suitable buckle methods.

[0074] Specifically, in Figure 1In the illustrated embodiment, the first sealing member 30 may be plate-shaped. The first mounting member 32 may be ring-shaped. The first sealing member 30 may be connected to the inner side of the first mounting member 32. The second mounting member 52 may be fixedly connected to a side of the pot cover 11 close to the cooking cavity 26.

[0075] Please combine Figure 1 In some embodiments, the first mounting member 32 is provided with a mounting hole 34. The second mounting member 52 includes a mounting portion 54 and a connecting portion 56. The connecting portion 56 connects the pot cover 11 and the mounting portion 54. The connecting portion 56 is located in the mounting hole 34. The mounting portion 54 holds the first mounting member 32 against the pot cover 11.
[0076] In this way, the first mounting member 32 can be further fixedly connected to the pot cover 11 .
[0077] Specifically, the surface of the first mounting member 32 may be provided with a mounting hole 34, and the mounting hole 34 may be provided with a plurality of holes. The second mounting member 52 may include a limiting column. The second mounting member 52 is provided with a mounting portion 54 and a connecting portion 56. The connecting portion 56 may be columnar. One end of the connecting portion 56 may be connected to the bottom of the pot cover 11. The end of the connecting portion 56 away from the pot cover 11 may be connected to the mounting portion 54. In one embodiment, when the sealing assembly 28 seals the second exhaust hole 14, the connecting portion 56 may be inserted into the mounting hole 34, and the end of the mounting portion 54 connected to the connecting portion 56 may abut the first mounting member 32 on the pot cover 11, so that the first mounting member 32 can be fixedly connected to the pot cover 11 to prevent the first mounting member 32 from slipping. In addition, the diameter of the mounting portion 54 near the connection with the connecting portion 56 is greater than the diameter of the connecting portion 56, so that after the second mounting member 52 is inserted through the mounting hole 34, the mounting portion 54 can abut the first mounting member 32 on the pot cover 11.
[0078] Please combine Figure 1 In certain embodiments, the first mounting member 32 and / or the mounting portion 54 are elastic.
[0079] This makes installation and disassembly easier.
[0080] Specifically, in one embodiment, the first mounting member 32 is elastic. The first mounting member 32 may be an elastic member. In one embodiment, the mounting portion 54 is elastic. The mounting portion 54 may be an elastic member. In one embodiment, both the first mounting member 32 and the mounting portion 54 are elastic. Both the first mounting member 32 and the mounting portion 54 may be elastic members.

[0081] Please combine Figure 1 In some embodiments, the sealing assembly 28 includes a second sealing member 36. The second sealing member 36 seals and connects the first mounting member 32 and the pot cover 11.
[0082] In this way, the cooking cavity 26 can be sealed to prevent gas leakage.
[0083] Specifically, the second sealing member 36 may include a sealing ring. The second sealing member 36 may be disposed around the outer side of the first mounting member 32. In one embodiment, when the sealing assembly 28 is mounted on the pot cover 11, the second sealing member 36 may seal the first mounting member 32 and the pot cover 11, thereby forming a seal for the cooking cavity 26 to prevent gas leakage.
