[0049] Please refer to Figures 1 to 5 A cooking device 100 according to an embodiment of the utility model includes a pot cover assembly 10, a pot body 26 and a float assembly 30. The pot cover assembly 10 includes a pot cover 11 and an exhaust device 20. The pot cover 11 is provided with a first exhaust hole 12 and a second exhaust hole 14. The exhaust device 20 is connected to the pot cover 11 and seals the first exhaust hole 12. The pot body 26 is connected to the pot cover 11. A cooking cavity 28 is formed in the pot body 26. The pot cover 11 covers the cooking cavity 28. The float assembly 30 is detachably mounted at the second exhaust hole 14 and seals the second exhaust hole 14. The float assembly 30 includes a float valve 32 and an exhaust channel 33. The float valve 32 can be movably connected to the pot cover 11. When the float valve 32 is located in the first position, the exhaust channel 33 is communicated with the cooking cavity 28. When the float valve 32 is located in the second position, the exhaust channel 33 is isolated from the cooking cavity 28.
[0050] In the above-mentioned cooking device 100, the float assembly 30 is detachably installed at the second exhaust hole 14 and seals the second exhaust hole 14. The cooking device 100 can perform pressure cooking. When the cooking device 100 needs to perform pressureless cooking, the float assembly 30 can be removed, and the cooking cavity 28 can be connected to the outside of the cooking device 100 through the second exhaust hole 14, so that the pressureless cooking function of the cooking device 100 can be realized, avoiding the user from using additional electrical appliances for pressureless cooking.
[0051] 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 26. 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 14. The first exhaust hole 12 and the second exhaust hole 14 may be disposed at different positions on the pot cover 11.
[0052] Generally, the transverse dimension of the valve body of the float valve 32 is not much different from the transverse dimension of the exhaust pipe provided with the first exhaust hole 12, and the float assembly 30 is detachably mounted at the second exhaust hole 14, thereby, it can be determined that the exhaust area of the second exhaust hole 14 is larger than the exhaust area of the first exhaust hole 12. In one embodiment, the aperture of the second exhaust hole 14 can be larger than the aperture of the first exhaust hole 12. The exhaust device 20 can be connected to the pot cover 11 and can seal the first exhaust hole 12. A cooking cavity 28 can be formed in the pot body 26. The pot body 26 can be connected to the pot cover 11, and the pot cover 11 can cover the cooking cavity 28, so that food can be placed in the cooking cavity 28 for cooking.
[0053] The float assembly 30 is detachably mounted at the second exhaust hole 14 and seals the second exhaust hole 14. In one embodiment, the float assembly 30 can be detached from the pot cover 11 to open the second exhaust hole 14. Optionally, the float valve 32 can be columnar. The float valve 32 can be movably connected to the pot cover 11. In one embodiment, when the cooking device 100 performs pressureless cooking, the float assembly 30 can be detached from the pot cover 11 along the H direction, so that the float assembly 30 is in a state of opening the second exhaust hole 14, and the cooking device 100 can perform pressureless cooking.
[0054] In one embodiment, when the cooking device 100 performs pressure cooking, the float assembly 30 is installed at the second exhaust hole 14 and seals the second exhaust hole 14. The function of the float valve 32 is to exhaust the cold air in the cooking cavity 28. Under normal temperature and pressure, the float valve 32 can sink along the H direction and be in the first position, and the exhaust channel 20 is connected with the cooking cavity 28, so that the inside and outside of the cooking cavity 28 are connected through the exhaust channel 20; when the cooking cavity 28 is pressurized, the float valve 32 can float along the H direction to the second position, and the exhaust channel 20 is isolated from the cooking cavity 28, so that the inside and outside of the cooking cavity 28 are isolated, and the cooking device 100 can perform pressure cooking.
[0055] In some embodiments, the exhaust area of the second exhaust hole 14 is greater than or equal to 30 mm^2 (square millimeters).
[0056] 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.
[0057] 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.
[0058] 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.
[0059] 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.
[0060] In some embodiments, the exhaust area of the second exhaust hole 14 is greater than the exhaust area of the first exhaust hole 12 .
[0061] In this way, the cooking device 100 can smoothly perform pressure-free cooking.
[0062] Specifically, the transverse dimension of the valve body of the float valve 32 is not much different from the transverse dimension of the exhaust pipe provided with the first exhaust hole 12, and the float assembly 30 is detachably mounted at the second exhaust hole 14, so that the exhaust area of the second exhaust hole 14 is larger than the exhaust area of the first exhaust hole 12. After the float assembly 30 is removed from the pot cover 11, the second exhaust hole 14 is opened, and 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.
[0063] In some embodiments, the exhaust area of the first exhaust hole 12 is less than or equal to 10 mm^2.
[0064] In this way, the cooking device 100 can smoothly perform pressure cooking to a certain extent.
[0065] 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.
[0066] 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.
[0067] 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.
[0068] When the cooking device 100 performs pressurized cooking, the float assembly 30 is mounted on the pot cover 11 and seals the second exhaust hole 14. When the cooking cavity 28 is not pressurized, the float valve 32 sinks to the first position, the inside and outside of the cooking cavity 28 are connected through the exhaust passage 33, and the air in the cooking cavity 28 can be exhausted through the exhaust passage 33. When the cooking cavity 28 is pressurized, the float valve 32 floats to the second position, and the exhaust passage 33 is isolated from the cooking cavity 28.
[0069] The exhaust valve 22 can play a pressure limiting function. Specifically, when the pressure in the cooking cavity 28 is less than the pressure limiting pressure of the exhaust valve 22, the exhaust valve 22 can seal the first exhaust hole 12 under the action of gravity, and the airflow generated in the cooking cavity 28 cannot be discharged through the first exhaust hole 12. As the cooking time progresses, the air pressure generated in the cooking cavity 28 becomes greater and greater. When the pressure in the cooking cavity 28 is greater than or equal to the pressure limiting pressure of the exhaust valve 22, the exhaust valve 22 is lifted up by the air pressure in the cooking cavity 28, so that the airflow in the cooking cavity 28 can be discharged through the first exhaust hole 12. In one example, the pressure limiting pressure of the exhaust valve 22 can be 70 kPa.
[0070] 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 22 releases pressure, the exhaust amount (loss amount) of airflow is less than the generation amount of airflow, thereby ensuring that after the exhaust valve 22 releases pressure, the cooking device 100 can still perform pressurized cooking smoothly.
[0071] Please combine Figure 1 and Figure 2 In some embodiments, the exhaust device 20 includes an exhaust valve 22 and an exhaust pipe 24. The exhaust pipe 24 passes through the pot cover 11. The exhaust valve 22 is movably mounted at one end of the exhaust pipe 24 away from the cooking cavity 28. The first exhaust hole 12 passes through the exhaust pipe 24.
[0072] In this way, the cooking apparatus 100 can perform pressure cooking through the exhaust device 20 .
[0073] Specifically, the exhaust valve 22 may be disposed near the top of the pot cover 11. The exhaust pipe 24 may pass through the pot cover 11, and one end of the exhaust pipe 24 away from the cooking cavity 28 may protrude from the top of the pot cover 11. The exhaust valve 22 may be movably mounted at one end of the exhaust pipe 24 away from the cooking cavity 28. The first exhaust hole 12 may pass through the exhaust pipe 24. In one embodiment, the cooking device 100 may perform pressurized cooking through the exhaust device 20, and the gas in the cooking cavity 28 may be discharged to the outside of the cooking device 100 through the first exhaust hole 12.
[0074] It should be noted that the cooking device 100 may be provided with an exhaust drive mechanism (not shown) near the exhaust valve 22. The exhaust drive mechanism may control the exhaust valve 22 to release pressure and exhaust when the air pressure in the cooking cavity 28 reaches a predetermined pressure, so that the air pressure in the cooking cavity 28 is less than the predetermined pressure, and the exhaust drive mechanism may drive the exhaust valve 22 to seal the first exhaust hole 12. In one example, when the cooking device 100 performs pressurized cooking, the exhaust valve 22 may reciprocate at one end of the first exhaust hole 12 away from the cooking cavity 28. 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.
[0075] In some embodiments, the exhaust passage 33 is disposed within the float valve 32 .
[0076] In this way, an exhaust passage 33 may be provided in the float valve 32 .
[0077] Specifically, please combine Figure 4 and Figure 5 The float valve 32 may be provided with an air inlet 35 and an air outlet 37. The air inlet 35 may be connected to the air outlet 37 through the exhaust passage 33. The air inlet 35 may be provided on a side wall of the float valve 32 near the bottom of the float valve 32. The air outlet 37 may be provided on a side wall of the float valve 32 near the top of the float valve 32.
[0078] In one embodiment, during the process of pressure cooking of the cooking device 100, the float valve 32 may be located at the first position first, and the exhaust passage 33 may be connected to the cooking cavity 28. As the air pressure in the cooking cavity 28 gradually increases, the float valve 32 may be pushed to gradually rise. When the pressure in the cooking cavity 28 is much greater than the gravity of the float valve 32, the float valve 32 may rise to the second position, and the exhaust passage 33 may be isolated from the cooking cavity 28. That is, when the float assembly 30 seals the second exhaust hole 14, the cooking device 100 needs to exhaust air for a period of time in the initial stage of cooking before entering pressure cooking. After the cooking device 100 enters pressure cooking, the float valve 32 rises to the maximum height, which may indicate that the cooking device 100 is in a pressure state and the pot cover 11 cannot be opened.
[0079] Please combine Figure 1 and Figure 3 In some embodiments, the float assembly 30 includes a first sealing member 38. The first sealing member 38 is provided with a mounting hole 42. The float valve 32 is provided with the mounting hole 42 so that the float valve 32 can be lifted and lowered. The first sealing member 38 is detachably connected to the pot cover 11 and seals the second exhaust hole 14.
[0080] In this way, when the cooking device 100 performs pressureless cooking, the exhaust volume can be increased, thereby improving the reliability of achieving pressureless cooking.
[0081] Specifically, in Figure 3 In the illustrated embodiment, the first sealing member 38 may be in the shape of a disk. A mounting hole 42 may be provided near the middle of the first sealing member 38. In one embodiment, along the H direction, the bottom of the float valve 32 may move in a direction away from the mounting hole 42. In one embodiment, along the H direction, the bottom of the float valve 32 may move in a direction close to the mounting hole 42.
[0082] When the cooking device 100 performs pressureless cooking, the float assembly 30 can be removed from the pot cover 11, so that the first seal 38 opens the second exhaust hole 14, and the cooking cavity 28 can exhaust gas through the second exhaust hole 14, thereby increasing the exhaust volume and improving the reliability of pressureless cooking. When the cooking device 100 performs pressure cooking, the first seal 38 can be connected to the pot cover 11, so that the first seal 38 seals the second exhaust hole 14, thereby achieving pressure cooking.
[0083] In some embodiments, please combine Figures 4a to 4d The exhaust passage 33 is arranged around the outer peripheral side of the float valve 32 .
[0084] In this way, the air in the cooking cavity 28 can be discharged out of the cooking cavity 28 through the outer peripheral side surface of the float valve 32 .
[0085] Specifically, in one embodiment, the exhaust passage 33 is annular and can be disposed around the outer peripheral side of the float valve 32 , so that air can be discharged from the cooking cavity through the float valve 32 in a 360-degree circumferential direction.
[0086] In some embodiments, please combine Figures 4a to 4d The float assembly 30 includes a first sealing member 38, which is provided with a through hole 381. The float valve 32 can be raised and lowered through the through hole 381. An exhaust passage 33 is formed between the hole wall of the through hole 381 and the outer peripheral side of the float valve 32. The first sealing member 38 is detachably connected to the pot cover 11 and seals the second exhaust hole 14.
[0087] In this way, when the cooking device 100 performs pressureless cooking, the exhaust volume can be increased, thereby improving the reliability of achieving pressureless cooking.
[0088] Specifically, in Figure 4c and Figure 4d In the illustrated embodiment, the first sealing member 38 may be disc-shaped. A through hole 381 may be provided near the middle of the first sealing member 38. In one embodiment, along the H direction, the bottom of the float valve 32 may move away from the through hole 381. In one embodiment, along the H direction, the bottom of the float valve 32 may move toward a direction close to the through hole.
[0089] When the cooking device 100 performs pressureless cooking, the float assembly 30 can be removed from the pot cover 11, so that the first seal 38 opens the second exhaust hole 14, and the cooking cavity 28 can exhaust gas through the second exhaust hole 14, thereby increasing the exhaust volume and improving the reliability of pressureless cooking. When the cooking device 100 performs pressure cooking, the first seal 38 can be connected to the pot cover 11, so that the first seal 38 seals the second exhaust hole 14, thereby achieving pressure cooking.
[0090] Please combine Figure 1 and Figure 3 as well as Figures 4a to 4d In some embodiments, the float valve 32 includes a valve body 34 and a second sealing member 40. The valve body 34 is provided with a first sealing member 38 so as to be lifted and lowered. The second sealing member 40 is connected to one end of the valve body 34 extending into the cooking cavity 28. When the float valve 32 is in the first position, the second sealing member 40 is spaced apart from the first sealing member 38. When the float valve 32 is in the second position, the second sealing member 40 is connected to the first sealing member 38 and seals the exhaust passage 33.
