[0003] In the related art, an electric pressure cooker includes a pot body and an upper cover assembly. A closed cooking cavity is formed by buckling the upper cover assembly on the pot body. Among them, the upper cover assembly includes an outer cover and an inner cover arranged inside the outer cover. The inner cover rotates relative to the outer cover so that the cover teeth of the inner cover are locked with the pot teeth of the pot body.

[0004] However, in the existing inner cover, it is connected to the outer cover through a buckle structure, and the contact surface between the inner cover and the outer cover is large, resulting in a large frictional force when the inner cover rotates. Summary of the Utility Model

The positioning member is installed at the first radial gap between the temperature measuring member and the inner cover, and the temperature measuring member and the inner cover radially clamp the positioning member. When the inner cover rotates, due to the radial positioning effect of the positioning member, the inner cover will not deviate from the rotation center during the rotation process. And due to the radial positioning of the positioning member, there is a second radial gap between the outer side wall of the inner cover and the inner side wall of the outer cover. When the inner cover rotates, the inner cover and the outer cover will not contact. Thus, the contact area between the inner cover and the outer cover can be reduced to reduce the frictional force when the inner cover rotates.

[0008] Furthermore, the positioning member is made of an elastic material. The positioning member made of an elastic material can form a good radial positioning for the inner cover and is convenient for the positioning member to form a tight fit with the inner cover during pressure cooking.

The driving column passes through the rotating plate. The upper end of the driving column is drivingly connected to the rotating rod, and the lower end of the driving column is connected to the inner cover. The rotating rod can drive the rotating plate and the inner cover to rotate through the driving column. With the above structure, when the handle rotates, it drives the rotating rod to rotate. The rotating rod drives the driving column to rotate. The driving column drives the inner cover to rotate. At the same time, the driving column drives the rotating plate to rotate, and the rotating plate drives the turntable to rotate. Thus, it is realized that only by rotating the handle can the exhaust pipe and the inner cover be driven to rotate; and / or, the outer cover includes a face cover and a lining. The lining is arranged between the face cover and the inner cover. The temperature measuring member is connected to the lining. The turntable is rotatably arranged on the face cover.

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0056] As Figures 1 to 25 shown, the embodiment of the present invention provides an upper cover assembly, which is covered on the pot body. The upper cover assembly includes an outer cover 10, an inner cover 20, and a positioning member 60. The outer cover 10 is provided with a temperature measuring member 11; the inner cover 20 is rotatably arranged on the outer cover 10. The inner cover 20 is provided with a cover tooth 21 that cooperates with the pot tooth of the pot body. A positioning hole 27 is provided at the center of the inner cover 20. The temperature measuring member 11 passes through the positioning hole 27 and has a first radial clearance L1 with the inner cover 20; the positioning member 60 is installed in the first radial clearance L1 in a manner of being radially clamped by the temperature measuring member 11 and the inner cover 20, so that there is a second radial clearance L2 between the outer side wall of the inner cover 20 and the inner side wall of the outer cover 10.

[0057] Applying the technical solution of the present invention, the upper cover assembly includes an outer cover 10, an inner cover 20, and a positioning member 60. The positioning member 60 is installed at the first radial clearance L1 between the temperature measuring member 11 and the inner cover 20, and the temperature measuring member 11 and the inner cover 20 are used to radially clamp the positioning member 60. When the inner cover 20 rotates, due to the radial positioning function of the positioning member 60, the inner cover 20 will not deviate from the rotation center during the rotation process. Moreover, due to the radial positioning of the positioning member 60, there is a second radial clearance L2 between the outer side wall of the inner cover 20 and the inner side wall of the outer cover 10. When the inner cover 20 rotates, the inner cover 20 and the outer cover 10 will not contact. Thus, the contact area between the inner cover 20 and the outer cover 10 can be reduced to reduce the friction force when the inner cover 20 rotates.

[0058] In this embodiment, the positioning member 60 is made of an elastic material. The positioning member 60 made of an elastic material can form a good radial positioning for the inner lid 20 and facilitate the formation of a tight fit between the positioning member 60 and the inner lid 20 during pressure cooking.

[0059] It should be noted that when there is no pressure in the cooking cavity of the cooking appliance, there is an axial gap between the positioning member 60 and the inner lid 20, enabling the inner lid 20 to rotate smoothly. During pressure cooking, due to the pressure, the positioning member 60 is pressed against the inner lid 20 to form a tight fit.

[0060] As Figure 24 shown, the positioning member 60 has a plugging hole 61 penetrating vertically. The temperature measuring member 11 is inserted into the plugging hole 61 and is in positioning cooperation with the plugging hole 61 in the radial direction. With the above structure, the plugging hole 61 can be used to position the temperature measuring member 11 for the positioning member 60, keeping the positioning member 60 at the first radial gap.

[0061] As Figure 24 shown, the outer side wall of the positioning member 60 has an annular plugging groove 62. The inner lid 20 includes a mounting plate 28, and the mounting plate 28 encloses a positioning hole 27. The mounting plate 28 extends into the annular plugging groove 62 and is in positioning cooperation with the annular plugging groove 62 in the radial direction. With the above structure, the annular plugging groove 62 can be used to position the positioning member 60 for the inner lid 20, so that the inner lid 20 will not deviate from the rotation center during rotation.

[0062] As Figure 2 shown, the upper cover assembly further includes a pressure limiting assembly 30. The pressure limiting assembly 30 includes an exhaust pipe 31 and a pressure limiting valve. The exhaust pipe 31 penetrates vertically through the outer lid 10 and the inner lid 20, and the pressure limiting valve is arranged at the upper end of the exhaust pipe 31. The pressure limiting valve can be used to form a high pressure in the cooking cavity, thereby accelerating the stewing efficiency of the food. After cooking, the pressure limiting valve is opened, and the pressurized air in the pot body is discharged through the exhaust pipe 31 penetrating through the outer lid 10 and the inner lid 20.

[0063] In this embodiment, an eccentric hole is further provided on the inner lid 20. The eccentric hole is located at the side of the positioning hole, and the lower end of the exhaust pipe 31 passes through the eccentric hole and is in sealing cooperation with the inner lid 20.

[0064] It should be noted that since the inner lid 20 needs to rotate, the exhaust pipe 31 is eccentrically arranged on the inner lid 20. The exhaust pipe 31 needs to rotate with the inner lid 20, and the outer lid 10 needs to be provided with an avoidance structure to avoid the exhaust pipe 31.

[0065] As Figure 4 and Figure 13As shown, the upper cover assembly further includes a driving assembly 40. The driving assembly 40 includes a driving member 41 and a turntable 42. The driving member 41 is drivingly connected to the inner cover 20 to enable the inner cover 20 to rotate around the axis of the temperature measuring member 11. The exhaust pipe 31 passes through the turntable 42, and the driving member 41 is drivingly connected to the turntable 42, so that the turntable 42 is rotatably arranged on the outer cover 10. With the above arrangement, the driving member 41 can drive the inner cover 20 to rotate, and the driving member 41 drives the turntable 42 to rotate, thereby driving the exhaust pipe 31 to rotate.

[0066] In this embodiment, the exhaust pipe 31 is fixedly connected to the turntable 42.

[0067] As Figure 4 and Figure 5 shown, the driving member 41 includes a handle 411 and a rotating rod 412. The handle 411 is rotatably arranged on the outer cover 10 around its own axis. The rotating rod 412 is arranged inside the outer cover 10. One end of the rotating rod 412 is fixedly connected to the handle 411, and the other end of the rotating rod 412 is drivingly connected to both the inner cover 20 and the turntable 42 to enable the inner cover 20 and the turntable 42 to rotate. By rotating the handle 411, the rotating rod 412 can be driven to rotate, and the inner cover 20 and the turntable 42 can be driven to rotate by the rotating rod 412, which has the advantage of simple operation.

[0068] Wherein, the rotating rod 412 extends in the horizontal direction.

[0069] As Figure 4 and Figure 5 shown, the driving assembly 40 further includes a rotating plate 43 and a driving column 44 extending vertically. The rotating plate 43 is connected to the turntable 42. The driving column 44 passes through the rotating plate 43. The upper end of the driving column 44 is drivingly connected to the rotating rod 412, and the lower end of the driving column 44 is connected to the inner cover 20. The rotating rod 412 can drive the rotating plate 43 and the inner cover 20 to rotate through the driving column 44. With the above structure, when the handle 411 rotates, it drives the rotating rod 412 to rotate. The rotating rod 412 drives the driving column 44 to rotate. The driving column 44 drives the inner cover 20 to rotate. At the same time, the driving column 44 drives the rotating plate 43 to rotate, and the rotating plate 43 drives the turntable 42 to rotate. Thus, only by rotating the handle 411, the exhaust pipe 31 and the inner cover 20 can be driven to rotate.

[0070] In this embodiment, the handle 411 is located at the side of the temperature measuring member 11. Since the driving column 44 drives the inner cover 20 to rotate around the axis of the temperature measuring member 11, and the rotating rod 412 is fixedly connected to the handle 411, therefore, for the rotating rod 412 relative to the inner cover 20, the rotation centers of the two are different. When the rotating rod 412 drives the inner cover 20 to rotate, an avoidance structure needs to be provided between the rotating rod 412 and the driving column 44. The avoidance structure is a strip-shaped groove having the same extending direction as the rotating rod 412. The driving column 44 is inserted into the strip-shaped groove, and the driving column 44 can slide in the strip-shaped groove when the rotating rod 412 rotates.

[0071] As Figure 4 and Figure 13 shown, the outer cover 10 includes a face cover 12 and a lining 13. The lining 13 is disposed between the face cover 12 and the inner cover 20. The temperature measuring member 11 is connected to the lining 13. The turntable 42 is rotatably disposed on the face cover 12. A first avoidance groove is provided on the turntable 42. The handle 411 passes through the first avoidance groove and is connected to the lining 13. A second avoidance groove for avoiding the exhaust pipe 31 is provided on the lining 13. With the outer cover 10 having the above structure, the face cover 12 can be used to shield the lining 13. At the same time, the turntable 42 is disposed on the face cover 12, and the temperature measuring member 11 is disposed on the lining 13. When the handle 411 rotates, the turntable 42 can avoid the handle 411 by means of the first avoidance groove, and the lining 13 can avoid the exhaust pipe 31 by means of the second avoidance groove.

[0072] As Figures 18 to 21 shown, a chute is provided on the inner side wall of the outer cover 10, and an insertion block 22 and a clamping block 23 are provided on the outer side wall of the inner cover 20. When the inner cover 20 rotates relative to the outer cover 10, the lower surface of the insertion block 22 and the lower surface of the clamping block 23 are respectively in guiding cooperation with the bottom wall of the chute, and the outer side wall of the insertion block 22 and the outer side wall of the clamping block 23 are respectively in clearance fit with the side wall of the chute. By making both the insertion block 22 and the clamping block 23 in guiding cooperation with the chute, a guiding effect can be formed on the rotation of the inner cover 20, making the rotation of the edge of the inner cover 20 smoother and avoiding excessive swing of the inner cover 20 during rotation.

[0073] In this embodiment, the chute includes a first chute 14 and a second chute 15. When the inner cover 20 rotates relative to the outer cover 10, the lower surface of the insertion block 22 is in guiding cooperation with the bottom wall of the first chute 14, and the lower surface of the clamping block 23 is in guiding cooperation with the bottom wall of the second chute 15.

[0074] As Figure 12 and Figure 18As shown in the figure, the outer cover 10 is provided with a button 16 and a hook 17. The button 16 is movably arranged vertically, and the hook 17 is movably arranged horizontally. The button 16 can drive the hook 17 to move horizontally. The outer cover 10 is also provided with a through groove 18 communicating with the sliding groove. The hook 17 has a clamping position for clamping and cooperating with the clamping block 23 and an avoidance position for avoiding the clamping block 23. When the hook 17 is in the avoidance position, the clamping block 23 can move into the sliding groove through the through groove 18. When the hook 17 moves to the clamping position, the hook surface of the hook 17 is flush with the bottom wall of the sliding groove and can be clamped and cooperated with the clamping block 23. By pressing the button 16, the hook 17 can be driven to move horizontally, so that the hook 17 moves from the clamping position to the avoidance position. At this time, the clamping block 23 can be installed into the sliding groove through the through groove 18. Then release the button 16, so that the hook 17 moves from the avoidance position to the clamping position, and the hook 17 can be clamped and cooperated with the clamping block 23 to limit the inner cover 20 and prevent the inner cover 20 from falling off the outer cover 10.

[0075] In this embodiment, springs are arranged on both the button 16 and the hook 17, and the restoring force provided by the springs can realize the automatic reset of the button 16 and the hook 17.

[0076] In this embodiment, the hook surface of the hook 17 is flush with the groove wall of the second sliding groove 15. When the inner cover 20 is installed on the outer cover 10, the hook 17 is used to limit and support the inner cover 20. After the inner cover 20 rotates relative to the outer cover 10, the groove wall of the second sliding groove 15 is used to limit and support the inner cover 20.

[0077] Specifically, when installing the inner cover 20, the inner cover 20 is inclined relative to the outer cover 10 to insert the insertion block 22 into the first sliding groove 14, and then push the inner cover 20. Thus, with the insertion block 22 as the swing point, the inner cover 20 swings towards the direction close to the outer cover 10, so that the clamping block 23 extends into the second sliding groove 15, and the inner cover 20 is installed on the outer cover 10. And the inner cover 20 rotates relative to the outer cover 10 below the outer cover 10, and the groove wall of the first sliding groove 14 supports the insertion block 22, and the groove wall of the second sliding groove 15 supports the clamping block 23. When the cooking appliance is pressed down, the inner cover 20 is pushed to float relative to the outer cover 10. At this time, the insertion block 22 moves upward in the first sliding groove 14, and the clamping block 23 moves upward in the second sliding groove 15. When disassembling the inner cover 20, pull the inner cover 20. Thus, with the insertion block 22 as the swing point, the inner cover 20 swings towards the direction away from the outer cover 10, so that the clamping block 23 disengages from the second sliding groove 15, and the inner cover 20 is inclined relative to the outer cover 10 to facilitate taking out the insertion block 22 from the first sliding groove 14.

[0078] Among them, the inner cover 20 includes a pressure-bearing cover 24 and a fixed cover 25 arranged on the pressure-bearing cover 24. The insertion block 22 and the clamping block 23 are both arranged on the outer side wall of the fixed cover 25. The fixed cover 25 is used to facilitate the arrangement of the insertion block 22 and the clamping block 23.

[0079] In this embodiment, the inner lid 20 further includes a pot mouth sealing ring. The pot mouth sealing ring and the fixing cover 25 are respectively located on both sides of the pressure-bearing cover 24, and the pot mouth sealing ring and the fixing cover 25 are fixed on the pressure-bearing cover 24 by steel needles.

[0080] As Figures 6 to 11 shown, the upper cover assembly further includes a top column 50 that is floatingly arranged on the outer lid 10. The inner lid 20 is detachably arranged on the outer lid 10. When the inner lid 20 is separated from the outer lid 10, the top column 50 floats downward and is in a stop fit with the rotating rod 412. When the inner lid 20 is assembled to the outer lid 10, the inner lid 20 abuts against the top column 50 to make the top column 50 float upward and separate from the rotating rod 412. After the inner lid 20 is removed from the outer lid 10, the top column 50 can form a stop fit with the rotating rod 412, thereby preventing the rotating rod 412 from rotating, so as to prevent the outer lid 10 from being directly covered on the pot body after the inner lid 20 is removed, resulting in misoperation and causing damage.

[0081] Moreover, after the inner lid 20 is installed on the outer lid 10, the inner lid 20 can abut against the top column 50 to separate the top column 50 from the rotating rod 412, and then drive the inner lid 20 to rotate through the rotating rod 412, so that the pot teeth and the cover teeth 21 are locked or unlocked.

[0082] As Figure 7 and Figure 9 shown, a blocking protrusion 413 is provided on the side wall of the rotating rod 412, and a blocking block 51 is provided on the side wall of the top column 50. When the inner lid 20 is separated from the outer lid 10, the blocking protrusion 413 can be in a stop fit with the blocking block 51. The stop structure with the cooperation of the blocking protrusion 413 and the blocking block 51 has the advantages of simple structure and convenient processing.

[0083] Wherein, a return spring 52 extending in the vertical direction is sleeved on the outer periphery of the top column 50. The two ends of the return spring 52 are respectively abutted against the side wall of the top column 50 and the inner wall of the outer lid 10. When the inner lid 20 is separated from the outer lid 10, the return force provided by the return spring 52 can drive the top column 50 to automatically reset and be in a stop fit with the rotating rod 412.

[0084] As Figure 22 and Figure 23 shown, an avoidance hole is provided on the outer lid 10. The hole wall of the avoidance hole has a plurality of positioning grooves 26. The plurality of positioning grooves 26 are arranged at intervals along the circumferential direction of the avoidance hole. A plurality of positioning protrusions 111 are provided on the side wall of the temperature measuring member 11. The plurality of positioning protrusions 111 are respectively inserted into the plurality of positioning grooves 26. Through the positioning structure with the cooperation of the positioning protrusions 111 and the positioning grooves 26, the positioning of the temperature measuring member 11 can be more stable, and the temperature measuring member 11 can be prevented from rotating during the rotation of the inner lid 20.

[0085] Among them, an annular boss 112 is provided at the upper end of the temperature measuring member 11, and the annular boss 112 is erected on the inner wall of the outer cover 10. By using the cooperation of the annular boss 112 and the outer cover 10, the temperature measuring member 11 can be limited, thereby preventing the temperature measuring member 11 from falling off the outer cover 10.

[0086] In this embodiment, the temperature measuring member 11 is connected to the outer cover 10 by screws.

[0087] Another embodiment of the present utility model provides a cooking appliance, which includes an upper cover assembly and a cooking pot body. The upper cover assembly is pivotally covered above the cooking pot body, and the upper cover assembly is the upper cover assembly provided above. When the inner cover 20 rotates, due to the radial positioning function of the positioning member 60, the inner cover 20 will not deviate from the rotation center during the rotation process. Moreover, due to the radial positioning of the positioning member 60, a second radial gap is formed between the outer side wall of the inner cover 20 and the inner side wall of the outer cover 10. When the inner cover 20 rotates, the inner cover 20 and the outer cover 10 will not come into contact. Thereby, the contact area between the inner cover 20 and the outer cover 10 can be reduced to reduce the frictional force when the inner cover 20 rotates.

[0088] Among them, the cooking appliance includes an electric pressure cooker and a multi-functional cooking pan with a pressure cooking function.
