Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to an electric pressure cooker with adjustable pressure release speed. Background Art

[0002] The electric pressure cooker is an upgraded product of the traditional pressure cooker and rice cooker. It combines the advantages of pressure cookers and rice cookers, completely solving the safety problems of pressure cookers and eliminating the potential safety hazards of ordinary pressure cookers that have troubled consumers for many years. Its thermal efficiency is greater than 80%, saving time and electricity. However, in order to ensure safe use, it is generally necessary to wait until the air pressure in the pot is the same as the atmospheric pressure before opening the lid after cooking is completed.

[0003] Existing electric pressure cookers generally discharge the high pressure in the pot through the exhaust hole. Under normal circumstances, it takes a certain amount of time for the air pressure in the electric pressure cooker to be completely discharged. If you want to quickly discharge the air pressure in the pot, you usually increase the exhaust port to achieve the purpose of rapid pressure relief. At this time, you usually need to manually pull the valve switch upward. The height to which the valve switch is pulled determines how fast the pressure in the pot is relieved. Since this process is performed manually, it is impossible to judge whether the height to which the valve switch is pulled is appropriate. If the valve is pulled too high, it is easy to cause the pressure in the pot to be released too quickly. When liquid is stored in the inner pot, it is easy to cause the liquid to boil and gush, thereby contaminating the interior of the electric pressure cooker.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0005] In view of the problems in the related technology, the utility model provides an electric pressure cooker with adjustable pressure release speed to overcome the above technical problems existing in the existing related technology.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses an electric pressure cooker with adjustable pressure relief speed, comprising a pot body, a pot cover is arranged on the top of the pot body, a conical groove is opened on the top of the pot cover, a conical plug is arranged inside the conical groove, a mounting cylinder is fixedly connected to the top of the pot cover, a moving disk is movably connected inside the mounting cylinder, the moving disk is fixedly connected to the conical plug, a driving assembly is arranged on one side of the moving disk, the top of the pot cover is fixedly connected to a dial, and a driving end of the driving assembly is rotatably connected to the dial.

[0008] Furthermore, a spring is fixedly connected to the top of the movable plate, the other end of the spring is fixedly connected to the top of the inner wall of the mounting tube, and an air hole is opened at the bottom of the mounting tube.

[0009] Furthermore, the driving assembly includes a driving groove, a screw is rotatably connected inside the driving groove, a driving block is threadedly connected outside the screw, a moving groove is opened on the outside of the moving disk, and the driving block is movably connected to the moving groove.

[0010] Furthermore, the driving assembly also includes a small bevel gear, the bottom end of the screw rod passes through the driving block and is fixedly connected to the small bevel gear, the outer side of the small bevel gear is meshed with a large bevel gear, and one side of the large bevel gear is fixedly connected to a driving rod.

[0011] Furthermore, one end of the driving rod passes through the mounting tube and is fixedly connected to a knob, and a pointer is fixedly connected to the outer side of the knob, and the pointer is arranged on the front side of the dial.

[0012] Furthermore, a fixing column is fixedly connected to the top of the pot cover, the driving rod is rotatably connected to the fixing column, and the dial is fixedly connected to one end of the fixing column.

[0013] Furthermore, an installation cavity is opened inside the fixed column, a mounting plate is fixedly connected to the inner wall of the installation cavity, a switch is arranged on the top of the mounting plate, an indicator light is arranged on the outer side of the fixed column, the switch is electrically connected to the indicator light, a pressure plate is arranged on the top of the switch, and the pressure plate is fixedly connected to the driving rod.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model rotates the driving rod through the knob, and the driving rod drives the screw to rotate through the large bevel gear and the small bevel gear, and the rotating screw drives the driving block to move inside the driving groove. When the driving block contacts the top of the inner wall of the moving groove, it can drive the moving plate to move upward. At this time, a gap is generated between the conical plug and the conical groove, so that the air pressure inside the pot body can be leaked. When the driving rod is rotated, the setting of the pointer and the dial allows the operator to adjust the gap between the conical plug and the conical groove to a suitable size according to actual conditions, and make the pressure relief speed of the electric pressure cooker just right. In summary, when the high pressure cooker is depressurized, the operator can accurately adjust the pressure relief speed according to the type of food cooked inside the pot body, thereby effectively avoiding the situation where the pressure in the pot is relieved too quickly and the liquid boils and gushes.

[0016] 2. When the utility model adjusts the pressure relief speed of the electric pressure cooker, the driving rod can drive the pressure plate to rotate inside the installation cavity, and the pressure plate no longer presses the switch. At this time, the indicator light is on. The above arrangement enables the operator to rotate the driving rod again and reset it under the reminder of the indicator light after completing the pressure relief operation, thereby avoiding the electric pressure cooker from being in a pressure relief state the next time it is used, which will affect the cooking effect.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] See also Figure 1-Figure 7 As shown, the utility model is an electric pressure cooker with adjustable pressure relief speed, comprising a pot body 1, a pot cover 2 is arranged on the top of the pot body 1, a conical groove 3 is opened on the top of the pot cover 2, a conical plug 4 is arranged inside the conical groove 3, a mounting tube 5 is fixedly connected to the top of the pot cover 2, a movable disk 6 is movably connected inside the mounting tube 5, the movable disk 6 is fixedly connected to the conical plug 4, a driving assembly 7 is arranged on one side of the movable disk 6, a dial 8 is fixedly connected to the top of the pot cover 2, and a driving end of the driving assembly 7 is rotatably connected to the dial 8.

[0031] When rapid pressure relief is performed, the driving end of the driving assembly 7 is directly rotated to make the driving assembly 7 drive the movable disk 6 to move upward, and the movable disk 6 drives the conical plug 4 to move upward. At this time, a gap appears between the conical plug 4 and the conical groove 3. As the conical plug 4 continues to move upward, the gap between the two continues to increase. At the same time, the pressure relief speed inside the pot body continues to increase. At the same time, the operator observes the dial 8 and moves the conical plug 4 to a suitable height.

[0032] The conical plug 4 is moved by the driving component 7, so that the gap size between the conical plug 4 and the conical groove 3 can be adjusted, so that the speed of the electric pressure cooker during pressure relief can be adjusted. At the same time, the dial 8 cooperates with the driving component 7 to enable the operator to have a more intuitive understanding of the pressure relief speed. In summary, the operator can adjust the pressure relief speed of the electric pressure cooker according to actual conditions.

[0033] In one embodiment, for the above-mentioned movable plate 6, a spring 9 is fixedly connected to the top of the movable plate 6, and the other end of the spring 9 is fixedly connected to the top of the inner wall of the mounting tube 5, and an air hole 10 is opened at the bottom of the mounting tube 5.

[0034] The spring 9 can push the movable plate 6 downward and make the conical plug 4 at the bottom of the movable plate 6 inside the conical groove 3. When cooking in the electric pressure cooker, when the air pressure inside the electric pressure cooker reaches a certain limit, the conical plug 4 moves upward under the action of the air pressure and makes the movable plate 6 squeeze the spring 9. At this time, the high-pressure gas inside the pot body 1 flows to the outside of the pot body 1 through the gap between the conical plug 4 and the conical groove 3 and the air hole 10. When the air pressure inside the pot body 1 is lower than the limit value, the conical plug 4 is pushed by the spring 9 to fit together with the conical groove 3 again.

[0035] The arrangement of the spring 9 enables the electric pressure cooker to automatically release pressure when the internal pressure of the pot body 1 is too high during cooking, thereby ensuring the safety of the electric pressure cooker during use.

[0036] In one embodiment, for the above-mentioned driving component 7, the driving component 7 includes a driving groove 701, the internal rotation of the driving groove 701 is connected to a screw rod 702, the outer side of the screw rod 702 is threadedly connected to a driving block 703, and a moving groove 704 is opened on the outer side of the moving disk 6, and the driving block 703 is movably connected to the moving groove 704.

[0037] When the air pressure inside the pot body 1 is quickly released, the screw rod 702 can be rotated to drive the driving block 703 to move inside the driving groove 701. When the driving block 703 contacts the top of the inner wall of the moving groove 704, the moving disk 6 can also drive the conical plug 4 to move as the driving block 703 continues to move, so that the air pressure inside the pot body 1 can be quickly released.

[0038] The movable groove 704 is arranged so that when the air pressure inside the pot body 1 is too high and needs to be relieved during cooking, since the driving block 703 is in contact with the top of the inner wall of the movable groove 704 under normal circumstances, the tapered plug 4 will not be hindered by the driving block 703 when moving upward. This means that when the pot body 1 is cooking and the air pressure inside the pot body 1 is higher than the critical value, the electric pressure cooker can relieve the pressure normally.

[0039] In one embodiment, for the above-mentioned driving component 7, the driving component 7 also includes a small bevel gear 705, the bottom end of the screw rod 702 passes through the driving block 703 and is fixedly connected to the small bevel gear 705, the outer side of the small bevel gear 705 is meshed with a large bevel gear 706, and one side of the large bevel gear 706 is fixedly connected to a driving rod 707.

[0040] When the screw 702 is driven, the driving rod 707 is directly rotated, so that the driving rod 707 drives the large bevel gear 706 to rotate, and the large bevel gear 706 drives the small bevel gear 705 to rotate, so that the small bevel gear 705 can drive the screw 702 to rotate.

[0041] When the screw 702 is driven, the driving rod 707 can be directly rotated, so that the driving rod 707 directly drives the screw 702 through the large bevel gear 706 and the small bevel gear 705, and one end of the driving rod 707 is arranged at the edge of the pot cover 2, so that when the screw 702 is driven by the driving rod 707, the operator's hands will not be burned by hot air.

[0042] In one embodiment, for the above-mentioned driving rod 707, one end of the driving rod 707 passes through the mounting tube 5 and is fixedly connected to a knob 11, a pointer 12 is fixedly connected to the outer side of the knob 11, the pointer 12 is arranged on the front side of the dial 8, a fixing column 13 is fixedly connected to the top of the pot cover 2, the driving rod 707 is rotatably connected to the fixing column 13, and the dial 8 is fixedly connected to one end of the fixing column 13.

[0043] The driving rod 707 is rotated by the knob 11, and the knob 11 can drive the pointer 12 to rotate on the front side of the dial 8. At this time, the operator can know the speed of pressure release of the electric pressure cooker through the pointer 12 and the dial 8.

[0044] The fixed column 13 can support the driving rod 707, so that the stability of the driving rod 707 during rotation is guaranteed. The setting of the pointer 12 and the dial 8 allows the operator to more accurately adjust the appropriate pressure relief speed of the electric pressure cooker according to the type of food being cooked.

[0045] In one embodiment, for the above-mentioned fixed column 13, an installation cavity 14 is opened inside the fixed column 13, and a mounting plate 15 is fixedly connected to the inner wall of the mounting cavity 14. A switch 16 is arranged on the top of the mounting plate 15, and an indicator light 17 is arranged on the outer side of the fixed column 13. The switch 16 is electrically connected to the indicator light 17, and a pressure plate 18 is arranged on the top of the switch 16, and the pressure plate 18 is fixedly connected to the driving rod 707.

[0046] When the pressure relief speed of the electric pressure cooker is adjusted, the driving rod 707 drives the pressing plate 18 to rotate inside the installation cavity 14. At this time, the pressing plate 18 no longer presses the switch 16, and the indicator light 17 lights up directly.

[0047] The lighted indicator light 17 can remind the operator so that after the pressure cooker is depressurized, the operator can remember to turn the knob 11 and reset it, so that the next time the electric pressure cooker is used, the electric pressure cooker will not be in a depressurized state and the cooking effect will not be affected.

[0048] Through the above technical solution, 1. The driving rod 707 is rotated by the knob 11, and the driving rod 707 drives the screw 702 to rotate through the large bevel gear 706 and the small bevel gear 705. The rotating screw 702 drives the driving block 703 to move inside the driving groove 701. When the driving block 703 contacts the top of the inner wall of the moving groove 704, it can drive the moving disk 6 to move upward. At this time, a gap is generated between the conical plug 4 and the conical groove 3, so that the air pressure inside the pot body 1 can be leaked. When the driving rod 707 is rotated, the setting of the pointer 12 and the dial 8 allows the operator to adjust the gap between the conical plug 4 and the conical groove 3 to a suitable size according to actual conditions, and make the pressure relief speed of the electric pressure cooker just right. , in summary, when relieving the pressure of the high pressure cooker, the operator can accurately adjust the pressure relief speed according to the type of food cooked inside the pot body 1, thereby effectively avoiding the situation where the pressure in the pot is relieved too quickly and the liquid boils and gushes; 2. When adjusting the pressure relief speed of the electric pressure cooker, the driving rod 707 can drive the pressing plate 18 to rotate inside the installation cavity 14, and the pressing plate 18 no longer presses the switch 16, and the indicator light 17 lights up at this time. The above setting enables the operator to rotate and reset the driving rod 707 again under the reminder of the indicator light 17 after completing the pressure relief operation, thereby avoiding the electric pressure cooker from being in a pressure relief state when the electric pressure cooker is used next time. The cooking effect is affected.
