[0045] Please refer to Figure 1 and Figure 2 A cooking device 100 according to an embodiment of the utility model includes a pot cover assembly 10, a pot body 36 and a sealing assembly 40. The pot cover assembly 10 includes a pot cover 11 and an exhaust valve 30. The pot cover 11 is provided with a first exhaust hole 12 and a second exhaust hole 22. The exhaust valve 30 is connected to the pot cover 11 and seals the first exhaust hole 12. The pot body 36 is connected to the pot cover 11. A cooking cavity 38 is formed in the pot body 36. The pot cover 11 covers the cooking cavity 38. The sealing assembly 40 includes a driving member 42 and a movable member 44. The driving member 42 is configured to drive the movable member 44 to open the second exhaust hole 22 or close the second exhaust hole 22, wherein the exhaust area of ​​the second exhaust hole 22 is greater than or equal to 30 mm^2 (square millimeters).

[0046] In the above-mentioned cooking device 100, by adding a second exhaust hole 22 on the pot cover 11, the exhaust area of ​​the second exhaust hole 22 is greater than or equal to 30mm^2, and the driving member 42 can drive the movable member 44 to open the second exhaust hole 22 or close the second exhaust hole 22. When the cooking device 100 needs to perform pressureless cooking, the driving member 42 drives the movable member 44 to open the second exhaust hole 22, so that the cooking cavity 38 is connected to the outside of the cooking device 100 through the second exhaust hole 22, thereby increasing the exhaust volume, avoiding the decrease in cooking speed and the increase in cooking time due to insufficient exhaust volume of the exhaust valve 30.

[0047] 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 36. The height direction of the cooking device 100 may be represented by H. Along the H direction, the pot cover 11 may be provided with a first exhaust hole 12 and a second exhaust hole 22. The first exhaust hole 12 and the second exhaust hole 22 may be provided at different positions on the pot cover 11. The exhaust valve 30 may be connected to the pot cover 11 and may seal the first exhaust hole 12. A cooking cavity 38 may be formed in the pot body 36. The pot body 36 may be connected to the pot cover 11, and the pot cover 11 may cover the cooking cavity 38, so that food may be placed in the cooking cavity 38 for cooking.

[0048] The driving member 42 may be a screw motor or a push rod motor.

[0049] In one embodiment, the screw motor includes a screw motor body and a screw, and optionally, the movable member 44 can be a screw. Alternatively, the movable member 44 can be a component connected to the screw. The screw motor can drive the movable member 44 to move forward and backward in a rotating manner, and the direction of rotation determines whether the movable member 44 moves forward or backward relative to the screw motor.

[0050] In one embodiment, the push rod motor includes a push rod motor body and a push rod, and optionally, the movable member 44 can be a push rod. Alternatively, the movable member 44 can be a component connected to the push rod. The push rod motor can drive the movable member 44 to move forward and backward in a linear motion. The driving member 42 can be connected to the pot cover 11. The driving member 42 can be fixedly connected to the pot cover 11. In one embodiment, the driving member 42 can drive the movable member 44 along the H direction to close the second exhaust hole 22, so that the cooking device 100 can perform pressure cooking. In one embodiment, the driving member 42 can drive the movable member 44 along the H direction to open the second exhaust hole 22, so that the cooking device 100 can perform pressureless cooking. That is, when the cooking device 100 needs to perform pressureless cooking, the driving member 42 can drive the movable member 44 to open the second exhaust hole 22, so that the cooking cavity 38 is connected to the outside of the cooking device 100 through the second exhaust hole 22, thereby increasing the exhaust volume, avoiding the decrease in cooking speed and the increase in cooking time due to insufficient exhaust volume of the exhaust valve 30.

[0051] It should be noted that, in one embodiment, when the cooking device 100 is in the non-pressure cooking mode, the pressure in the cooking cavity 38 can be detected by the detection device to be lower than 4 kPa, and the movable member 44 can open the second exhaust hole 22, and the gas in the cooking cavity 38 can be discharged from the second exhaust hole 22. Optionally, the driving member 42 can also be connected to the exhaust valve 30, and the driving member 42 can drive the exhaust valve 30 to open the first exhaust hole 12, so that the gas in the cooking cavity 38 can also be discharged from the first exhaust hole 12. In one embodiment, when the cooking device 100 is in the pressure cooking mode, the movable member 44 can close the second exhaust hole 22, and the gas in the cooking cavity 38 can be discharged from the first exhaust hole 12.

[0052] In addition, when the cooking device 100 performs pressurized cooking, the driving member 42 can drive the movable member 44 to seal the second exhaust hole 22, and the pressure in the cooking cavity 38 rises. The locking force of the driving member 42 to lock the movable member 44 can be greater than or equal to the pressure of the air pressure in the cooking cavity 38 at the end of the movable member 44, so that the movable member 44 can seal the second exhaust hole 22 and prevent the movable member 44 from being pushed.

[0053] The exhaust area of ​​the second exhaust hole 22 is greater than or equal to 30 mm^2 (square millimeters), which can ensure to a certain extent that the exhaust area of ​​the second exhaust hole 22 meets the relevant exhaust speed design. Specifically, in one embodiment, the second exhaust hole 22 is a cylindrical hole, and the exhaust area of ​​the cylindrical hole is the area of ​​the bottom surface of the cylinder. In one embodiment, the second exhaust hole 22 is a prismatic hole, and the exhaust area of ​​the prismatic hole is the bottom surface area of ​​the prism. The bottom surface of the prism includes but is not limited to a triangle, a quadrilateral, a pentagon or other polygon. The prism may include a straight prism and an oblique prism.

[0054] Optionally, for other regular or irregular shaped second exhaust holes 22, the exhaust area of ​​the second exhaust hole 22 may be the area of ​​a plane shape obtained by a cross section perpendicular to the axis of the second exhaust hole 22. 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.

[0055] The exhaust area of ​​the second exhaust hole 22 is S2, and the exhaust area of ​​the second exhaust hole 22 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.

[0056] In some embodiments, the exhaust area of ​​the second exhaust hole 22 is greater than the exhaust area of ​​the first exhaust hole 12 .

[0057] In this way, the cooking device 100 can smoothly perform pressure-free cooking.

[0058] Specifically, the exhaust valve 30 can play a pressure limiting function. When the pressure in the cooking cavity 38 is less than the pressure limiting pressure of the exhaust valve 30, the exhaust valve 30 can seal the first exhaust hole 12 under the action of gravity, and the airflow generated in the cooking cavity 38 cannot be discharged through the first exhaust hole 12. As the cooking time progresses, the air pressure generated in the cooking cavity 38 becomes greater and greater. When the pressure in the cooking cavity 38 is greater than or equal to the pressure limiting pressure of the exhaust valve 30, the exhaust valve 30 is lifted by the air pressure in the cooking cavity 38, so that the airflow in the cooking cavity 38 can be discharged through the first exhaust hole 12. In one example, the pressure limiting pressure of the exhaust valve 30 can be 70 kPa.

[0059] The exhaust area of ​​the second exhaust hole 22 is larger than the exhaust area of ​​the first exhaust hole 12. After the driving member 42 drives the movable member 44 to open the second exhaust hole 22, the exhaust area of ​​the second exhaust hole 22 is larger than the exhaust area of ​​the first exhaust hole 12, so that the exhaust amount (loss amount) of the airflow generated by the cooking device 100 during the pressureless cooking process is greater than the generation amount of the airflow, so that the cooking device 100 can smoothly perform pressureless cooking.

[0060] In some embodiments, the exhaust area of ​​the first exhaust hole 12 is less than or equal to 10 mm^2.

[0061] In this way, the cooking device 100 can smoothly perform pressure cooking to a certain extent.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] When the cooking device 100 performs pressurized cooking, the driving member 42 can drive the movable member 44 to close the second exhaust hole 2214. The exhaust valve 30 can play a pressure limiting function. Specifically, when the pressure in the cooking cavity 38 is less than the pressure limiting pressure of the exhaust valve 30, the exhaust valve 30 can seal the first exhaust hole 12 under the action of gravity, and the airflow generated in the cooking cavity 38 cannot be discharged through the first exhaust hole 12. As the cooking time progresses, the air pressure generated in the cooking cavity 38 becomes greater and greater. When the pressure in the cooking cavity 38 is greater than or equal to the pressure limiting pressure of the exhaust valve 30, the exhaust valve 30 is lifted up by the air pressure in the cooking cavity 38, so that the airflow in the cooking cavity 38 can be discharged through the first exhaust hole 12. In one example, the pressure limiting pressure of the exhaust valve 30 can be 70kPa.

[0066] 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 30 releases pressure, the exhaust amount (loss amount) of airflow is less than the generation amount of airflow, thereby ensuring that after the exhaust valve 30 releases pressure, the cooking device 100 can still perform pressurized cooking smoothly.

[0067] In some embodiments, the self-locking force of the driving member 42 is greater than the pressure exerted on the end of the movable member 44 by the gas pressure in the cooking cavity 38 .

[0068] In this way, the movable part 44 can withstand pressure, ensuring that the cooking device works in a pressurized mode.

[0069] Specifically, when the cooking device 100 performs pressure cooking, the movable member 44 is required to close the second exhaust hole 22. The self-locking force of the driving member 42 is greater than the pressure of the gas pressure in the cooking cavity 38 acting on the end of the movable member 44, so that in the pressure cooking mode, the movable member 44 can withstand the pressure, and to a certain extent, avoid the situation where the movable member 44 is pushed open by the pressure in the cooking cavity 38, resulting in a decrease in the pressure in the cooking cavity 38, thereby ensuring the smooth progress of pressure cooking to a certain extent.

[0070] In some embodiments, the sealing assembly includes a first sealing member 19 , which is disposed on the wall of the second exhaust hole 22 . When the movable member 44 closes the second exhaust hole 22 , the first sealing member 19 is clamped between the movable member 44 and the wall of the second exhaust hole 22 .

[0071] Thereby, the sealing performance of the second exhaust hole 22 can be improved.

[0072] Specifically, when the movable part 44 closes the second exhaust hole 22, the first sealing part 19 is clamped between the movable part 44 and the hole wall of the second exhaust hole 22, so that the sealing between the movable part 44 and the hole wall of the second exhaust hole 22 can be improved, thereby improving the sealing of the second exhaust hole 22.

[0073] Optionally, the first seal 19 can be a sealing ring, and the two ends of the sealing ring along the axial direction of the second exhaust hole 22 can extend away from the second exhaust hole 22 and fit on the surface of the pot cover 11, thereby preventing the first seal 19 from shifting and affecting the sealing of the second exhaust hole 22.

[0074] Please combine Figure 1 , Figure 2 and Figure 3 In some embodiments, the pot cover 11 includes an inner cover 14 and a cover plate 16, and the sealing assembly 40 includes a second sealing member 20. The pot cover 11 is formed with a mounting hole 18. The mounting hole 18 passes through the inner cover 14 and the cover plate 16. The second sealing member 20 is disposed in the mounting hole 18. The second sealing member 20 seals and connects the inner cover 14 and the cover plate 16. The second sealing member 20 is formed with a second exhaust hole 22.

[0075] In this way, the second exhaust hole 22 can be opened through the second sealing member 20 , so that the second sealing member 20 seals and connects the inner cover 14 , the cover plate 16 , and the movable member 44 , thereby sealing the second exhaust hole 22 .

[0076] Specifically, in Figure 3 In the illustrated embodiment, the inner cover 14 and the cover plate 16 may be disposed at the bottom of the pot cover 11, and the inner cover 14 may be located above the cover plate 16. In one embodiment, the pot cover 11 may be formed with a mounting hole 18, and the mounting hole 18 may penetrate the inner cover 14 and the cover plate 16. The second sealing member 20 may include a sealing ring. The second sealing member 20 is formed with a second vent hole 22.

[0077] In one embodiment, when the movable member 44 closes the second exhaust hole 22 , the second sealing member 20 can seal the inner cover 14 , the cover plate 16 and the movable member 44 , thereby sealing the second exhaust hole 22 .

[0078] Please combine Figure 1 In some embodiments, the cooking device 100 includes an exhaust pipe 34. The exhaust pipe 34 passes through the pot cover 11. The exhaust valve 30 is movably installed at one end of the exhaust pipe 34 away from the cooking cavity 38. The exhaust pipe 34 is provided with a first exhaust hole 12.

[0079] In this way, the cooking device 100 can release pressure through the exhaust valve 30 to ensure the safety of the cooking device 100.

[0080] Specifically, the exhaust valve 30 may be disposed near the top of the pot cover 11. The exhaust pipe 34 may pass through the pot cover 11, and one end of the exhaust pipe 34 away from the cooking cavity 38 may protrude from the top of the pot cover 11. The exhaust valve 30 may be movably mounted at one end of the exhaust pipe 34 away from the cooking cavity 38. The exhaust pipe 34 is provided with a first exhaust hole 12.

[0081] When the pressure in the cooking cavity 38 is less than the pressure limiting pressure of the exhaust valve 30, the exhaust valve 30 can seal the first exhaust hole 12 under the action of gravity, and the airflow generated in the cooking cavity 38 cannot be discharged through the first exhaust hole 12. As the cooking time progresses, the air pressure generated in the cooking cavity 38 becomes greater and greater. When the pressure in the cooking cavity 38 is greater than or equal to the pressure limiting pressure of the exhaust valve 30, the exhaust valve 30 is lifted by the air pressure in the cooking cavity 38, so that the airflow in the cooking cavity 38 can be discharged through the first exhaust hole 12, thereby ensuring the safety of the cooking device 100 in the pressurized mode. In one example, the pressure limiting pressure of the exhaust valve 30 can be 70 kPa.

[0082] It should be noted that the cooking device 100 may be provided with an exhaust drive mechanism near the exhaust valve 30. The exhaust drive mechanism may control the exhaust valve 30 to release pressure and exhaust when the air pressure in the cooking cavity 3826 reaches a predetermined pressure, so that the air pressure in the cooking cavity 38 is less than the predetermined pressure, and the exhaust drive mechanism may drive the exhaust valve 30 to seal the first exhaust hole 12. In one example, when the cooking device 100 performs pressurized cooking, the exhaust valve 30 may reciprocate at one end of the first exhaust hole 12 away from the cooking cavity 38. Optionally, the predetermined pressure is less than the pressure limit of the exhaust valve 22. In one example, the predetermined pressure is 50 kPa, and the pressure limit of the exhaust valve 22 is 70 kPa.

[0083] Please combine Figures 5 to 8 In some embodiments, the movable member 44 includes a first movable segment 46 and a second movable segment 47. The first movable segment 46 connects the second movable segment 47 and the driving member 42. The diameter of the first movable segment 46 is greater than the diameter of the second movable segment 47. The second exhaust hole 22 includes a first hole 24 and a second hole 26. When the movable member 44 closes the second exhaust hole 22, the first movable segment 46 penetrates the first hole 24, and the second movable segment 47 penetrates and seals the second hole 26.

[0084] When the movable member 44 opens the second exhaust hole 22 , the second movable section 47 opens the second hole 26 so that the second hole 26 is connected to the outside of the cooking device 100 through the first hole 24 .

[0085] In this way, the second exhaust hole 22 can be closed by movable segments with different diameters.

[0086] Specifically, in Figures 5 to 8 In the illustrated embodiment, the first movable segment 46 may be cylindrical. The second movable segment 47 may be cylindrical. One end of the first movable segment 46 may be connected to the driving member 42, and the other end may be connected to the second movable segment 47. The diameter of the first movable segment 46 may be represented by D1, and the diameter of the second movable segment 47 may be represented by D2. The diameter D1 of the first movable segment 46 is greater than the diameter D2 of the second movable segment 47.

[0087] exist Figures 5 to 8 In the embodiment, the second hole 26 is arranged close to the cooking cavity 38, and the first hole 24 is arranged above the second hole 26. The aperture of the first hole 24 can be represented by d1, and the aperture of the second hole 26 can be represented by d2. The aperture d1 of the first hole 24 is larger than the aperture d2 of the second hole 26. In one embodiment, when the movable member 44 closes the second exhaust hole 22, the first movable section 46 penetrates the first hole 24, and the first hole 24 can communicate with the outside of the cooking device 100, and the second movable section 47 penetrates and seals the second hole 26, so that the cooking device 100 can perform pressure cooking.

[0088] In one embodiment, when the movable member 44 opens the second exhaust hole 22, the second movable section 47 opens the second hole 26 so that the second hole 26 is connected to the outside of the cooking device 100 through the first hole 24, and the gas in the cooking cavity 38 can be discharged, so that the cooking device 100 can perform pressure-free cooking.

[0089] Please combine Figures 5 to 10 In some embodiments, the pot cover 11 includes an inner cover 14 and a cover plate 16, the inner cover 14 is provided with a first hole 24, the cover plate 16 is provided with a second hole 26, and the sealing assembly includes a third sealing member 54. When the second movable section 47 penetrates and seals the second hole 26, the third sealing member 54 seals and connects the first movable section 46 and the cover plate 16.

[0090] In this way, when the cooking apparatus 100 performs pressure cooking, the sealing performance of the second hole 26 can be improved.

[0091] Specifically, the third seal 54 may include a sealing ring. The third seal 54 may be annular. A partial cross section of the third seal 54 may be L-shaped. In one embodiment, when the cooking device 100 performs pressure cooking, the third seal 54 may seal and connect the first movable section 46 and the cover plate 16. Specifically, the end surface of the first movable section 46 may press a portion of the third seal 54 between the end surface of the first movable section 46 and the cover plate 16, thereby improving the sealing performance of the second hole 26.

[0092] In some embodiments, the third sealing member 54 is at least disposed on an end surface of the first movable segment 46 connected to the second movable segment 47 and surrounds the second movable segment 47 .

[0093] Thereby, the sealing performance of the second exhaust hole 22 can be further improved.

[0094] Specifically, the diameter of the first movable segment 46 is greater than that of the second movable segment 47 , so that an end of the first movable segment 46 connected to the second movable segment 47 forms an end surface, and the third sealing member 54 includes a first portion disposed on the end surface.

[0095] When the movable part 44 closes the second exhaust hole 22, the first part is clamped between the end surface and the upper surface of the cover plate 16. The first part surrounds the second movable segment 47 and the third sealing member 54 can seal the end surface of the first movable segment 46 and the cover plate 16 from the circumference of the second movable segment 47, thereby further improving the sealing of the second exhaust hole 22.

[0096] Optionally, the third sealing member 54 further includes a second portion that is attached to the circumferential side of the first movable segment 46 , and the first portion is connected to the second portion, so that the third sealing member 54 can be more firmly installed on the first movable segment 46 .

[0097] Please combine Figure 7 and Figure 8 In some embodiments, a first thread is provided on the circumferential side surface of the second movable segment 47, and a second thread is provided on the hole wall of the second hole 26. When the movable member 44 closes the second exhaust hole 22, the first thread and the second thread are connected in a cooperative manner, and when the movable member 44 opens the second exhaust hole 22, the first thread and the second thread are separated.

[0098] Therefore, the second exhaust hole 22 can be closed by means of a threaded connection.

[0099] Specifically, the driving member 42 may include a screw motor, which may drive the movable member 44 to move forward and backward in a rotating manner, and the direction of rotation determines whether the movable member 44 moves forward or backward relative to the screw motor. When the movable member 44 initially opens the second exhaust hole 22, the driving member 42 may drive the movable member 44 to rotate in a first direction, so that the movable member 44 moves forward and extends into the second hole 26, and the first thread on the second movable section 47 is connected in a matching manner with the second thread on the hole wall of the second hole 26. When the movable member 44 is screwed into place, the first thread is connected in a matching manner with the second thread to close the second exhaust hole 22.

[0100] When the second exhaust hole 22 is opened, the driving member 42 can drive the movable member 44 to rotate in the second direction, so that the movable member 44 retreats. The second movable section 47 withdraws from the second hole 26, and the portion where the first thread and the second thread are connected slowly decreases until the first thread is separated from the second thread, and the second exhaust hole 22 is opened. The second direction is opposite to the first direction.

[0101] Please combine Figure 7 and Figure 8 In some embodiments, a boss 61 is provided on the surface of the cover plate 16 facing the inner cover 14 , and the second hole 26 passes through the boss 61 .

[0102] Therefore, the boss 61 can make the threaded joint position thicker, further improving the sealing performance of the second exhaust hole 22 .

[0103] Specifically, in Figure 7 In the figure, the boss 61 is protruded on the upper surface of the cover plate 16, and the second hole 26 passes through the boss 61, so that the length of the second hole 26 is relatively large, and the length of the hole wall of the second hole 26 on which the second thread can be set is also relatively large, so that a longer second thread can be set. In combination with the first thread, the thread combination position of the first thread and the second thread can be made thicker, thereby further improving the sealing performance of the second exhaust hole 22.

[0104] Optionally, the boss 61 is connected to the cover plate 16 to form an integral structure. Optionally, the boss 61 and the cover plate 16 can be separate structures, and the boss 61 can be fixed to the cover plate 16 by welding or the like.

[0105] Please combine Figures 5 to 8 In some embodiments, the sealing assembly includes a fourth seal 50, the inner cover 14 and the cover plate 16 are spaced apart, the fourth seal 50 is located between the inner cover 14 and the cover plate 16, and the fourth seal 50 connects the inner cover 14 and the cover plate 16 along the circumferential direction of the second exhaust hole 22.

[0106] Thereby, the sealing performance inside the pot cover assembly 10 can be improved.

[0107] Specifically, the second exhaust hole 22 is formed with a first hole 24 and a second hole 26 in the inner cover 14 and the cover plate 16, respectively, and the fourth sealing member 50 is located between the inner cover 14 and the cover plate 16. The fourth sealing member 50 connects the inner cover 14 and the cover plate 16 along the circumferential direction of the second exhaust hole 22, thereby, the fourth sealing member 50 can surround the space between the inner cover 14 and the cover plate 16 to form an exhaust space connecting the first hole 24 and the second hole 26. When the movable member 44 opens the second exhaust hole 22, the gas can enter the first hole 24 through the exhaust space from the second hole 26, and be discharged from the first hole 24 to the outside of the pot cover assembly 10, thereby preventing the gas from flowing to other places of the pot cover assembly 10 through the gap between the inner cover 14 and the cover plate 16, thereby improving the sealing inside the pot cover assembly 10.

[0108] Please combine Fig. 9 and Fig.10 In some embodiments, at least a portion of the second hole 26 is a tapered hole that gradually expands in a direction away from the pot body, and the end of the second movable segment 47 away from the first movable segment 46 is a tapered portion that gradually expands in a direction away from the pot body. The tapered portion is adapted to the tapered hole, and the driving member 42 is configured to drive the movable member 44 to move to a different position compared to the pot cover 11 to change the opening area of ​​the second hole 26.

[0109] Thereby, the opening area of ​​the second hole 26 can be adjusted.

[0110] Specifically, the movable member 44 can move along the axial direction of the second hole 26. When the movable member 44 closes the second exhaust hole 22, the length of the portion of the movable member 44 extending into the second hole 26 is the longest. When opening the second hole 26, the driving member 42 can drive the movable member 44 (in a rotational or linear motion) to move away from the pot body, so that the second hole 26 can be opened. The opening area of ​​the second hole 26 is related to the lifting position of the movable member 44.

[0111] Since at least a portion of the second hole 26 is a tapered hole that gradually expands in a direction away from the pot body, the end of the second movable section 47 away from the first movable section 46 is a tapered portion that gradually expands in a direction away from the pot body, and the tapered portion is adapted to the tapered hole. When the movable member 44 is raised or lowered to different positions, the opening area of ​​the second hole 26 formed is different, thereby achieving an adjustable opening area of ​​the second hole 26, and the space between the second movable section 47 and the hole wall of the second hole 26 can form an exhaust channel, that is, the exhaust channel is adjustable.

[0112] Please combine Fig. 9 and Fig.10 In some embodiments, the second exhaust hole 22 includes a first opening 57 and a second opening 59, the first opening 57 faces the cooking cavity, and the second opening 59 faces away from the cooking cavity. When the movable member 44 closes the second exhaust hole 22, the length of the movable member 44 extending from the first opening 57 toward the cooking cavity is greater than 1 mm (millimeter), and / or, when the movable member 44 opens the second exhaust hole 22, the distance between the movable member 44 and the second opening 59 is greater than 3 mm.

[0113] Thereby, the reliability of sealing and / or the patency of the second exhaust hole 22 can be ensured.

[0114] Specifically, in one embodiment, the movable member 44 may be cylindrical. Figures 1 to 10 When the movable member 44 seals the second exhaust hole 22, the length of the movable member 44 extending from the first opening 57 toward the cooking cavity is greater than 1 mm, and the length of the movable member 44 extending into the cooking cavity 38 is relatively large, thereby ensuring the reliability of the seal.

[0115] In some examples, H1=1 mm, 1.2 mm, 1.5 mm, 2.0 mm, 2.5 mm or other values ​​greater than 1 mm. The upper limit of H1 can be determined according to factors such as the space in the cooking cavity.

[0116] When the movable member 44 opens the second exhaust hole 22 , the distance between the movable member 44 and the second port 59 is greater than 3 mm. The movable member 44 is far away from the second exhaust hole 22 , thereby ensuring the patency of the second exhaust hole 22 .

[0117] In some examples, H2=3 mm, 3.2 mm, 3.5 mm, 4.0 mm, 4.5 mm or other values ​​greater than 3 mm. The upper limit of H2 can be determined according to factors such as the space in the pot cover assembly 10.

[0118] In some embodiments, the driving member 42 is configured to drive the movable member 44 to move to a different position compared to the pot cover 11 to change the opening area of ​​the second exhaust hole 22 .

[0119] Thus, the opening area of ​​the second exhaust hole 22 can be changed to realize more cooking modes of the cooking device 100.

[0120] Specifically, in one embodiment, the movable member 44 may be of variable diameter, and the driving member 42 may drive the movable member 44 to rise or fall to a specified height to achieve different opening areas of the second exhaust holes 22 , thereby achieving adjustable exhaust passages.

[0121] Please combine Fig. 9 and Fig.10 The second movable section 47 is of variable diameter, and the second hole 26 is also of variable diameter. The second movable section 47 is adapted to the shape of the second hole 26. Fig. 9 and Fig.10 In the embodiment, the end of the second movable section 47 away from the first movable section 46 is a tapered portion that gradually expands in the direction away from the pot body, corresponding to the tapered hole portion of the second hole 26. When the movable member 44 is raised or lowered to different positions, the opening area of ​​the second hole 26 is different, thereby realizing the adjustable exhaust passage. Fig. 9 The cooking device 100 can operate in a pressurized mode, and the second exhaust hole 22 is closed. Fig.10 When the second exhaust hole 22 is opened, the cooking device 100 can operate in a non-pressure mode.

[0122] Please combine Fig.11 and Fig.12 The movable member 44 includes a connecting portion 56 and a closing portion 58. The connecting portion 56 is connected to the closing portion 58. The driving member 42 drives the connecting portion 56 along a first direction to drive the closing portion 58 to close the second exhaust hole 22, so that the cooking cavity 38 is not connected to the outside of the cooking cavity 38, and drives the closing portion 58 to move to open the second exhaust hole 22, so that the cooking cavity 38 is connected to the outside of the cooking cavity 38.

[0123] Specifically, in Fig.12 In the illustrated embodiment, the driving member 42 may include a push rod motor. The connecting portion 56 may serve as a push rod of the push rod motor, or a component connected to a push rod of the push rod motor. Optionally, the connecting portion 56 may be columnar.

[0124] The closing portion 58 may be plate-shaped. The connecting portion 56 may be fixedly connected to the closing portion 58. Fig.11 and Fig.12 In one embodiment, when the cooking device 100 is required to perform pressure cooking, the driving member 42 can drive the connecting portion 56 to the left to drive the closing portion 58 to close the second exhaust hole 22, so that the cooking cavity 38 is not connected to the outside of the cooking cavity 38. In one embodiment, when the cooking device 100 is required to perform non-pressure cooking, the driving member 42 can drive the connecting portion 56 to the right to drive the closing portion 58 to move to open the second exhaust hole 22 so that the cooking cavity 38 is connected to the cooking cavity 38.

[0125] When the closing portion 58 moves from the leftmost side to the rightmost side at different strokes, or moves from the rightmost side to the leftmost side at different strokes, the closing portion 58 may be at different positions compared to the pot cover 11, thereby changing the opening area of ​​the second exhaust hole 22 and achieving adjustable exhaust passage.

[0126] Please combine Fig.11 and Fig.12 In some embodiments, the sealing assembly 40 includes a fifth sealing member 60. When the movable member 44 closes the second exhaust hole 22, the fifth sealing member 60 seals and connects the closing portion 58 and the pot cover 11.

[0127] In this way, the sealing performance of the second exhaust hole 22 can be improved.

[0128] Specifically, the fifth sealing member 60 may include a sealing ring. The fifth sealing member 60 may be annular. Two fifth sealing members 60 may be provided, and may be respectively provided on the top surface and the bottom surface of the closing portion 58.

[0129] Please combine Figure 3 In some embodiments, the pot cover 11 is provided with a groove 28. The driving member 42 is disposed in the groove 28. The cooking device 100 includes a cover plate 62. The cover plate 62 covers the groove 28. The cover plate 62 is provided with a third exhaust hole 64. The third exhaust hole 64 is connected to the groove 28.

[0130] In this way, when the cooking device 100 performs pressureless cooking, the gas in the cooking cavity 38 can be discharged to the outside of the cooking device 100 through the third exhaust hole 64. At the same time, the drive member 42 is arranged in the groove 28 to make the structure compact.

[0131] Specifically, a groove 28 may be provided at the top of the pot cover 11. A mounting hole 18 may be provided at the bottom wall of the groove 28. The second sealing member 20 may be disposed in the mounting hole 18. The second sealing member 20 may be provided with a second exhaust hole 22. The driving member 42 may be disposed in the groove 28. In one embodiment, when the cooking device 100 performs pressureless cooking, the gas in the cooking cavity 38 may be discharged into the groove 28 through the second exhaust hole 22, and may eventually be discharged to the outside of the cooking device 100 from the third exhaust hole 64. The driving member 42 is disposed in the groove 28 and then closed by the cover plate 62, thereby avoiding the protrusion of the structure and making the structure compact.
