[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0037]

Steaming equipment

[0038] Figure 1 is a diagram of the steaming equipment provided in the embodiment of the present application.

[0039] As shown in the embodiment of the present application, a cooking device is provided, which comprises a cooking pot 100 and a cover opening device 1. The cooking pot 100 is generally used for cooking raw materials of food in the industries of brewing, food, solid fermentation, etc. The cover opening device 1 is used for opening and closing the cooking pot 100. Figure 1

[0040] Figures 2-3 is a schematic view of a cooking pot provided in the embodiment of the present application.

[0041] As shown in the embodiment of the present application, a cooking device is provided, which comprises a cooking pot 100 and a cover opening device 1. The cooking pot 100 is generally used for cooking raw materials of food in the industries of brewing, food, solid fermentation, etc. The cover opening device 1 is used for opening and closing the cooking pot 100. Figures 2-3

[0042] In the embodiment, the cooking device further comprises a pot body rotating mechanism 103 and a positioning mechanism 104. The pot body rotating mechanism 103 is used to drive the pot body 102 to rotate for cooking operation. The pot body rotating mechanism 103 is arranged on both sides of the pot body 102, and can be specifically arranged as a motor-driven transmission bearing to drive the pot body 102 to rotate.

[0043] In the embodiment, the positioning mechanism 104 is provided with two, which are arranged on both sides of the pot body 102, respectively, and position the pot body 102 by clamping the positioning slots 1021 provided on both sides of the pot body 102. The positioning mechanism 104 comprises a telescopic structure, which can be extended and clamped into the positioning slot 1021 only when the positioning slot 1021 corresponds to the position of the positioning mechanism 104. Therefore, the positioning mechanism 104 can limit the pot body 102, so that the pot body 102 stops at the same specified position (the position where the positioning slot 1021 corresponds to the position of the positioning mechanism 104) each time it stops rotating, thereby facilitating the cover opening device 1 to accurately position the pot body 102 to perform the opening and closing operation.

[0044] In the above embodiment, the rotary cooking pot is taken as an example for description, while in other embodiments of the present application, the type and structure of the cooking pot 100 can be adjusted according to actual conditions, for example, it can also be a non-rotary ordinary high-pressure cooking pot, which is not limited herein.

[0045]

Cover opening device

[0046] Figure 4 is a partial exploded view of the cooking pot 100 and the cover opening device 1 provided in the embodiment of the present application.

[0047] As shown in the embodiment of the present application, a cooking device is provided, which comprises a cooking pot 100 and a cover opening device 1. The cooking pot 100 is generally used for cooking raw materials of food in the industries of brewing, food, solid fermentation, etc. The cover opening device 1 is used for opening and closing the cooking pot 100. Figure 4 ​​As shown, in an embodiment of the present invention, the lid opening device 1 includes a rotating mechanism 2, a safety mechanism 3 and a sealing airbag 4. The rotating mechanism 2 can drive the lid 101 to rotate so as to separate from or join with the pot body 102.

[0048] Figures 5-6 This is a schematic diagram illustrating the cooperation between the pot lid and the rotating mechanism provided in an embodiment of the present invention.

[0049] like Figures 5-6 As shown, in an embodiment of the present invention, a circular abutment groove 1012 is formed on the upper surface of the pot lid 101 (the contact surface with the rotating mechanism 2), and three locking grooves 1013 are formed on the edge of the abutment groove 1012.

[0050] Figures 7-8 This is a schematic diagram of the claw extension / retraction state provided in an embodiment of the present invention.

[0051] like Figures 7-8 As shown, in an embodiment of the present invention, the rotating mechanism 2 includes a turntable 20 and three jaws 21 disposed below the turntable 20. Each jaw 21 has a base 210, a locking portion 211 extending from the base 210, and a receiving portion 212, with the receiving portion 212 disposed below the locking portion 211. When the jaw 21 retracts, the length of the receiving portion 212 extending in the axial direction is less than the length of the locking portion 211 extending in the axial direction; when the jaw 21 extends, the length of the receiving portion 212 extending in the axial direction is greater than the length of the locking portion 211 extending in the axial direction.

[0052] In this embodiment, the turntable 20 of the rotating mechanism 2 is coaxially arranged with the abutment groove 1012, and the three claws 21 below the turntable 20 respectively engage in the three locking grooves 1013 formed on the edge of the abutment groove 1012. Specifically, when the claws 21 grasp the pot lid 101, the rotating mechanism 2 as a whole approaches the pot lid 101 along the height direction H, the claws 21 are in a retracted state, and the locking part 211 extending from the base 210 abuts into the locking groove 1013, and the receiving part 212 below the locking part 211 is in the abutment groove 1012; then the claws 21 extend, and the receiving part 212 below the locking part 211 extends along the axial direction of the turntable 20 below the locking groove 1013. The length of the receiving part 212 extending in the axial direction is greater than the length of the locking part 211 extending in the axial direction, and the receiving part 212 is inserted into the lower part of the locking groove 1013; the locking part 211 and the receiving part 212 of the claw 21 engage and fix with the locking groove 1013 from the upper and lower sides, so that the rotating mechanism 2 can grasp and fix the pot lid 101 through the three claws 21, thereby realizing the rotating mechanism 2 driving the pot lid 101 to rotate and realizing the grasping and placing action of the pot lid 101.

[0053] In other embodiments of the present application, the connecting and fixing structure between the rotating mechanism 2 and the pot cover 101 can also be riveting, clamping jaws or any other form, which is not limited herein.

[0054] Figure 9 is a partial view of the cooking pot and cover opening device provided in an embodiment of the present application.

[0055] As shown in Figures 4-9 In an embodiment of the present application, the pot body 102 of the cooking pot 100 has a plurality of matching blocks 1022 protruding outward in the axial direction at the opening of the pot body 102; the pot cover 101 has a plurality of matching blocks 1014 protruding inward in the axial direction at the opening of the pot cover 101. When closing the pot cover 101, the rotating mechanism 2 drives the pot cover 101 to move above the pot body 102, and makes the plurality of matching blocks 1014 of the pot cover 101 staggered with the plurality of matching blocks 1022 of the pot body 102 (the projection of the plurality of matching blocks 1014 of the pot cover 101 and the plurality of matching blocks 1022 of the pot body 102 in the height direction H has no overlapping part). Then the rotating mechanism 2 drives the pot cover 101 to descend along the height direction H, so that the plurality of matching blocks 1014 of the pot cover 101 pass through between the plurality of matching blocks 102 of the pot body 102, and descend to the position where the plurality of matching blocks 1014 of the pot cover 101 completely exceed the plurality of matching blocks 102 of the pot body 102 in the height direction H. Then the rotating mechanism 2 drives the pot cover 101 to rotate, so that the matching blocks 1022 of the pot body 102 and the matching blocks 1014 of the pot cover 101 are aligned and abutted in the height direction H and are clamped with each other, thereby limiting the relative movement of the pot body 102 and the pot cover 101 in the height direction H, and locking the pot body 102 and the pot cover 101 into a combined state. Similarly, when opening the pot cover 101, the pot body 102 and the pot cover 101 are separated in the height direction H, and the plurality of matching blocks 1022 of the pot body 102 and the plurality of matching blocks 1014 of the pot cover 101 need to be rotated first so that the projection of the plurality of matching blocks 1022 of the pot body 102 and the plurality of matching blocks 1014 of the pot cover 101 in the height direction H has no overlapping part.

[0056] The rotating mechanism 2 is linked with the sealing air bag 4, and the sealing air bag 4 is arranged at the joint position of the pot cover 101 and the pot body 102, and uses air intake or exhaust to switch the sealing state between the pot cover 101 and the pot body 102.

[0057] Specifically, the opening of the pot body 102 is provided with a pot opening groove 1024, which is arranged as a ring-shaped groove formed around the opening of the pot body 102. The sealing air bag 4 of the cover opening device 1 is arranged in the pot opening groove 1024 and can abut against the pot cover 101 in the air intake state, thereby filling the gap between the pot body 102 and the pot cover 101 at the pot opening groove 1024, and achieving the sealing between the pot body 102 and the pot cover 101.

[0058] In the embodiment, the rotation mechanism 2 rotates the pot cover 101 to lock it with the pot body 102, and then the sealing air bag 4 is inflated to seal the pot cover 101 and the pot body 102. Before the rotation mechanism 2 rotates the pot cover 101 to separate it from the pot body 102, the sealing air bag 4 is deflated to release the sealing state between the pot cover 101 and the pot body 102, and the high-pressure gas in the pot body 102 can be released from the gap between the fitting blocks 1022. Thus, the efficiency of opening and closing the cover is improved, and the safety of the high-temperature and high-pressure operation of the steaming pot 100 is ensured.

[0059] The safety mechanism 3 in the cover opening device 1 can anchor the relative position of the locking combination between the pot body 102 and the pot cover 101. Referring to Figure 7 , the safety mechanism 3 is fixed to the platform part 1023 formed on one side of the pot body 102, and the safety mechanism 3 has an extension part 31 that can be engaged with the safety groove 1011 on the pot cover 101 in the extended state. In other words, when the extension part 31 is engaged with the safety groove 1011 on the pot cover 101, the relative rotation of the pot body 102 and the pot cover 101 in the circumferential direction can be limited.

[0060] In the embodiment, the extension part 31 is extended and retracted in response to the sealing state of the steaming pot 100. After the rotation mechanism 2 rotates the pot cover 101 to lock it with the pot body 102, the sealing air bag 4 is inflated to seal the pot cover 101 and the pot body 102, and then the extension part 31 of the safety mechanism 3 is extended to ensure that there is no relative rotation between the pot cover 101 and the pot body 102 after the steaming pot 100 is sealed. Before the sealing air bag 4 is deflated, the extension part 31 of the safety mechanism 3 is retracted first to ensure that the rotation mechanism 2 can rotate the pot cover 101 to separate it from the pot body 102 after the deflation of the sealing air bag 4 is completed. Thus, the efficiency and safety of opening and closing the cover of the steaming pot 100 are further improved.

[0061] In the embodiment of the present application, the cover opening device 1 further comprises a control mechanism (not shown) for controlling the rotation mechanism 2, the safety mechanism 3 and the sealing air bag 4, so that the extension part 31 of the safety mechanism 3 and the inflation and deflation of the sealing air bag 4 are controlled in linkage.

[0062] The control mechanism controls the rotation mechanism 2 to rotate the pot cover 101 to lock it with the pot body 102, and then the sealing air bag 4 is inflated for a specified time, and / or the sealing air bag 4 is deflated for a specified time, and then the rotation mechanism 2 is used to rotate the pot cover 101 to separate it from the pot body 102. Thus, the sealing state between the pot cover 101 and the pot body 102 can be maintained at all times when the pot cover 101 is combined with the pot body 102.

[0063] Preferably, in an embodiment of the present invention, the specified time for the sealing airbag 4 to vent / vent is 3-5 seconds. 3-5 seconds is sufficient for the sealing airbag 4 to be fully inflated or deflated, ensuring sufficient time for the sealing airbag 4 to vent after the lid 101 and the pot body 102 are joined, thus guaranteeing a sealing effect; and also, ensuring sufficient time for the sealing airbag 4 to deflate before the lid 101 and the pot body 102 are separated, preventing residual gas in the sealing airbag 4 from affecting the inflation and deflation during the next lid opening and closing operation.

[0064] Figures 10-11 This is a schematic diagram of the moving mechanism provided in an embodiment of the present invention.

[0065] like Figures 5-6 As shown in Figures 10-11, in an embodiment of the present invention, the cover opening device 1 further includes a lifting mechanism 5 and a moving mechanism 6.

[0066] The lifting mechanism 5 consists of two lifting cylinders. The two ends of the rotating mechanism 2 are fixed to the lifting cylinders located on both sides. The two lifting cylinders simultaneously extend and retract along the height direction H, driving the rotating mechanism 2 to move along the height direction H. The lifting mechanism 5 allows the pot lid 101, connected to the rotating mechanism 2, to move up and down along the height direction H, perpendicular to the contact surface between the pot lid 101 and the pot body 102, in a direction close to / away from the pot body 102. Compared to manual opening and closing of the lid, this significantly reduces or even eliminates friction and impact between the pot lid 101 and the pot body 102 during opening and closing, thereby improving the safety of the equipment and extending its service life.

[0067] The moving mechanism 6 is configured as a moving track 61 and a sliding block 62 that can reciprocate along the length direction L of the moving track 61. The lifting mechanism 5 is fixed to the sliding block 62 in the moving mechanism 6 and can move along the length direction L of the moving mechanism 6 following the sliding block 62.

[0068] Preferably, in this embodiment, the lifting mechanism 5 and the moving mechanism 6 are equipped with multiple sensors for detecting and controlling the moving position and moving distance.

[0069] In this embodiment, the pot body 102 is disposed at one end of the moving track 61. Figure 8 , 9 (Middle right end), the pot lid 101 can be placed at the other end of the moving track 61 ( Figure 9 (Right end) The moving mechanism 6 drives the pot lid 101 to move along the length direction L of the moving track 61, which helps to realize the combination / separation of the pot lid 101 and the pot body 102.

[0070] It is worth mentioning that in other embodiments of the present application, the mechanism for driving the pot cover 101 to move up and down can also be provided in the form of a combination of one or more structures such as a cylinder, a guide rail, a chain, a roller, etc., or designed as a unified three-axis moving structure, etc., which is not limited here.

[0071]

Thus, it is ensured that the pot 102 always remains in the specified position during the subsequent cover opening step, and because the relative position between the pot cover 101 and the pot 102 is fixed by the insurance mechanism 3 during the operation of the cooking device, the pot cover 101 combined with the pot 102 can be kept in the specified position to facilitate the positioning of the cover opening device 1.

[0076] Next, the lifting mechanism 5 in the cover opening device 1 moves along the length direction L of the moving mechanism 6 to move the rotary mechanism 2 above the pot 102; the rotary mechanism 2 descends along the height direction H of the lifting mechanism 5; the pawl 21 in the rotary mechanism 2 extends and is fixed with the pot cover 101; during this period, the position sensor, distance sensor, etc. can be used to feedback control whether the movements, lifting, rotation, engagement, etc. of the cover opening device 1 are in place.

[0077] Then, before the rotary mechanism 2 drives the pot cover 101 to rotate, the extension part 31 of the insurance mechanism 3 is controlled to retract, and then the sealing air bag 4 is controlled to deflate for 3 seconds; to ensure that the pot cover 101 and the pot 102 can rotate relative to each other without obstruction.

[0078] Finally, the rotating mechanism 2 drives the cover 101 to rotate and separate from the pot 102, the rotating mechanism 2 rises along the height direction H of the lifting mechanism 5, and then moves along the length direction L of the moving mechanism 6 to retract the cover 101.

Thus, the pot 102 is always kept at a specified position during the subsequent cover closing step, so that the cover opening device 1 drives the cover 101 to be positioned close.

[0083] Then, the lifting mechanism 5 in the cover opening device 1 moves along the length direction L of the moving mechanism 6 to move the rotating mechanism 2 carrying the cover 101 above the pot 102; the rotating mechanism 2 descends along the height direction H of the lifting mechanism 5 to make the cover 101 abut against the pot 102; and the rotating mechanism 2 drives the cover 101 to rotate to combine the cover 101 with the pot 102.

[0084] After the cover 101 combines with the pot 102, firstly, the sealing air bag 4 is controlled to be ventilated, and after a delay of 3s, the extension part 31 of the safety mechanism 3 provided on the pot 102 is controlled to be extended to engage with the safety groove 1015 on the cover 101, thereby limiting the relative position of the cover 101 and the pot 102 to ensure that the cover 101 and the pot 102 cannot rotate relative to each other again.

[0085] Finally, the claw 21 in the rotating mechanism 2 is retracted and disengaged from the lid 101. The rotating mechanism 2 is raised in the height direction H of the lifting mechanism 5 and then moved in the length direction L of the moving mechanism 6 to retract the rotating mechanism 2.

[0086] So far, the technical solutions of the present application have been described in conjunction with the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to the above specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without deviating from the principles of the present application, and the technical solutions after these changes or replacements will all fall within the protection scope of the present application.
