[0037] 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.

[0038] As Figures 1 to 11 shown, the embodiment of the present invention provides an upper cover assembly, which is covered on the cooking pot body. The upper cover assembly includes an outer cover 10, an inner cover 20, a pressure limiting assembly 30, and a driving assembly 40. The outer cover 10 is provided with a temperature measuring member 11; the inner cover 20 is detachably arranged below the outer cover 10. The inner cover 20 is provided with cover teeth 21 that cooperate with the pot teeth of the cooking pot body. The inner cover 20 has a through central hole 22 and an eccentric hole 23. The temperature measuring member 11 passes through the central hole 22 and is hermetically fitted with the inner cover 20; the pressure limiting assembly 30 includes an exhaust pipe 31. The exhaust pipe 31 is arranged vertically on the outer cover 10. The lower end of the exhaust pipe 31 passes through the eccentric hole 23 and is hermetically fitted with the inner cover 20.

[0039] Applying the technical solution of the present invention, the upper cover assembly includes an outer cover 10, an inner cover 20, and a pressure limiting assembly 30. The upper cover assembly is buckled on the cooking pot body, and the inner cover 20 is rotated, so that the cover teeth of the inner cover 20 can be locked with the pot teeth of the cooking pot body. After cooking is completed, the pressure air in the cooking pot body is discharged through the exhaust pipe 31 passing through the outer cover 10 and the inner cover 20. The inner cover 20 is rotated again, and the cover teeth of the inner cover 20 can be unlocked from the pot teeth of the cooking pot body to open the upper cover assembly. Since the temperature measuring member 11 and the exhaust pipe 31 are both arranged on the outer cover 10 and are hermetically fitted with the inner cover 20. When disassembling the inner cover 20, there is no need to disassemble the temperature measuring member 11 and the exhaust pipe 31, thus simplifying the disassembly steps of the inner cover 20 and making the operation more convenient.

[0040] In other embodiments, the exhaust pipe 31 can be passed through the central hole 22, and the temperature measuring member 11 can be passed through the eccentric hole 23, so that the inner cover 20 rotates around the axis of the exhaust pipe 31. Or, the temperature measuring member 11 and the exhaust pipe 31 are integrated, so that the inner cover 20 rotates around the axis of the integrated temperature measuring member 11 and the exhaust pipe 31. No matter which scheme is adopted, it is necessary to arrange the temperature measuring member 11 and the exhaust pipe 31 on the outer cover 10 so as not to affect the disassembly and assembly of the inner cover 20.

[0041] As Figure 2 shown, a first sealing ring 24 is provided at the central hole 22. The outer side wall of the first sealing ring 24 is in sealing fit with the hole wall of the central hole 22. The temperature measuring element 11 is inserted through the inner hole of the first sealing ring 24, and the inner side wall of the first sealing ring 24 abuts against the temperature measuring element 11. By using the method of sealing fit of the first sealing ring 24 with the central hole 22 and the temperature measuring element 11 respectively, it has the advantages of convenient material selection and low cost.

[0042] As Figure 2 and Figure 4 shown, the inner hole of the first sealing ring 24 includes a first hole section 241 and a second hole section 242 that are connected and communicate with each other. The first hole section 241 is located above the second hole section 242, and the aperture of the first hole section 241 is larger than that of the second hole section 242. The temperature measuring element 11 has a first sealing surface 111 and a second sealing surface 112 located below the first sealing surface 111. The first sealing surface 111 abuts against the first hole section 241, and the second sealing surface 112 abuts against the second hole section 242. By adopting the above sealing method, two-stage sealing can be formed, and further enhance the sealing performance between the first sealing ring 24 and the temperature measuring element 11.

[0043] As Figure 4 and Figure 5 shown, the first sealing surface 111 is an annular inclined surface, and the first hole section 241 is a tapered hole that cooperates with the annular inclined surface. The aperture of the first hole section 241 gradually decreases in the direction from top to bottom. By adopting the tapered sealing method, tight sealing between the first sealing surface 111 and the first hole section 241 can be achieved.

[0044] Among them, the second sealing surface 112 is a cylindrical surface 311, and the second hole section 242 is a tapered hole that cooperates with the cylindrical surface 311. The aperture of the second hole section 242 gradually decreases in the direction from top to bottom. By adopting the sealing method of matching the cylindrical surface 311 with the second hole section 242, the fit between the first sealing ring 24 and the temperature measuring element 11 can be made closer and closer, and further enhance the sealing performance between the first sealing ring 24 and the temperature measuring element 11.

[0045] As Figure 4 shown, the outer side wall of the first sealing ring 24 has an annular mounting groove 243. The inner cover 20 includes a mounting plate 26. The mounting plate 26 encloses the central hole 22, and a part of the mounting plate 26 is located in the annular mounting groove 243. By using the method of sealing fit of the annular mounting groove 243 with the inner cover 20, it has the advantages of simple installation structure and high sealing reliability.

[0046] As Figure 2 and Figure 6As shown in the figure, a second sealing ring 25 is provided at the eccentric hole 23. The outer side wall of the second sealing ring 25 is in sealing fit with the hole wall of the eccentric hole 23. The exhaust pipe 31 passes through the inner hole of the second sealing ring 25, and the inner side wall of the second sealing ring 25 abuts against the exhaust pipe 31. By using the second sealing ring 25 to be in sealing fit with the eccentric hole 23 and the exhaust pipe 31 respectively, it has the advantages of convenient material selection and low cost.

[0047] Among them, the second sealing ring 25 and the inner cover 20 can adopt either a direct sealing method or an indirect sealing method. In this embodiment, the second sealing ring 25 and the inner cover 20 adopt an indirect sealing method.

[0048] As Figure 6 and Figure 7 shown in the figure, the inner side wall of the second sealing ring 25 has an annular protrusion 251, and the annular protrusion 251 is in fit with the outer side wall of the exhaust pipe 31. By using the sealing method of the annular protrusion 251 being in fit with the exhaust pipe 31, it has the advantages of simple sealing structure and convenient processing.

[0049] As Figure 6 and Figure 7 shown in the figure, the second sealing ring 25 includes an annular ring 252 and a conical plate 253. The annular protrusion 251 is arranged on the inner side wall of the annular ring 252. The conical plate 253 is arranged on the inner side wall of the annular ring 252 and is located below the annular protrusion 251. The inner hole diameter of the conical plate 253 gradually decreases in the direction from top to bottom, and the outer side wall of the exhaust pipe 31 is in fit with the conical plate 253. By using the sealing method of the conical plate 253 being in fit with the exhaust pipe 31, it has the advantage of simple sealing structure.

[0050] Among them, the outer side wall of the exhaust pipe 31 includes a cylindrical surface 311 and a conical surface 312 located below the cylindrical surface 311. The annular protrusion 251 is in sealing fit with the cylindrical surface 311, and the conical surface 312 is in sealing fit with the conical plate 253, forming a two-stage seal, which enhances the sealing performance between the exhaust pipe 31 and the second sealing ring 25.

[0051] As Figure 2 shown in the figure, the upper cover assembly further includes a fixing cylinder 50 and a third sealing ring 60. The fixing cylinder 50 is installed on the inner cover 20 and is located at the eccentric hole 23. The second sealing ring 25 is clamped between the fixing cylinder 50 and the exhaust pipe 31 to seal the radial gap between the fixing cylinder and the exhaust pipe. The third sealing ring 60 is clamped between the fixing cylinder 50 and the inner cover 20 to seal the axial gap between the fixing cylinder and the inner cover. By using the second sealing ring 25, the fixing cylinder 50 and the exhaust pipe 31 can be sealed. By using the third sealing ring 60, the fixing cylinder 50 and the inner cover 20 can be sealed, so that the exhaust pipe and the inner cover have good sealing performance.

[0052] In this embodiment, an annular flange is provided at the upper end of the fixed cylinder 50. The bottom wall of the annular flange forms the wall of the fixing groove 51, and the upper end of the second sealing ring 25 is located above the annular flange.

[0053] Wherein, an anti-blocking cover is further provided on the outer periphery of the fixed cylinder 50. The anti-blocking cover can block the slurry outside the exhaust pipe 31 to prevent the exhaust pipe 31 from being blocked.

[0054] As Figures 9 to 11 shown, the outer cover 10 includes a face cover 12, a lining 13 and a turntable 14. The lining 13 is arranged between the face cover 12 and the inner cover 20. The temperature measuring member 11 is connected to the lining 13. The turntable 14 is rotatably arranged on the face cover 12. The exhaust pipe 31 is arranged on the turntable 14. A first 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 14 is arranged on the face cover 12, the temperature measuring member 11 is arranged on the lining 13, and the turntable 14 is used to drive the exhaust pipe 31 to rotate, so as to prevent interference between the inner cover 20 and the exhaust pipe 31 when the inner cover 20 rotates.

[0055] Specifically, the upper cover assembly further includes a driving assembly 40. The driving assembly 40 includes a handle 41 and a rotating rod 42. The handle 41 is rotatably arranged on the lining 13 around its own axis. One end of the rotating rod 42 is connected to the handle 41, and the other end of the rotating rod 42 is drivingly connected to both the inner cover 20 and the turntable 14, so that the inner cover 20 and the turntable 14 rotate. The rotation axis of the inner cover 20 is the axis of the temperature measuring member 11. A second avoidance groove for avoiding the handle 41 is provided on the turntable 14. When the handle 41 rotates, it drives the rotating rod 42 to rotate, and the rotating rod 42 drives the exhaust pipe 31 and the inner cover 20 to rotate. Therefore, by operating the handle 41, the exhaust pipe 31 and the inner cover 20 can be rotated simultaneously.

[0056] Wherein, the pressure limiting assembly 30 further includes a pressure limiting valve, and the pressure limiting valve covers the upper end of the exhaust pipe 31. The pressure limiting valve can block the exhaust pipe 31 to form a high-pressure state in the cooking cavity and improve the food stewing efficiency.

[0057] Specifically, the driving assembly 40 further includes a rotating plate and a driving column extending vertically. The rotating plate is connected to the turntable 14. The driving column passes through the rotating plate. The upper end of the driving column is drivingly connected to the rotating rod 42, and the lower end of the driving column is connected to the inner cover 20. The rotating rod 42 can drive the rotating plate and the inner cover 20 to rotate through the driving column. When the handle 41 rotates, it drives the rotating rod 42 to rotate, the rotating rod 42 drives the driving column to rotate, the driving column drives the inner cover 20 to rotate, and at the same time, the driving column drives the rotating plate to rotate, and the rotating plate drives the turntable 14 to rotate. Thus, only by rotating the handle 41, the exhaust pipe 31 and the inner cover 20 can be driven to rotate.

[0058] Among them, when the handle 41 rotates, the inner liner 13 can be avoided from the exhaust pipe 31 by using the first avoidance groove, and the turntable 14 can be avoided from the handle 41 by using the second avoidance groove.

[0059] In this embodiment, the handle 41 is located on the side of the temperature measuring member 11. Since the driving column drives the inner cover 20 to rotate about the axis of the temperature measuring member 11, and the rotating rod 42 is fixedly connected to the handle 41, therefore, relative to the inner cover 20, the rotation centers of the two are different. When the rotating rod 42 drives the inner cover 20 to rotate, an avoidance structure needs to be provided between the rotating rod 42 and the driving column. The avoidance structure is a strip-shaped groove having the same extending direction as that of the rotating rod 42, and the driving column is inserted into the strip-shaped groove. When the rotating rod 42 rotates, the driving column can slide in the strip-shaped groove.

[0060] Among them, a first sliding groove and a second sliding groove are provided on the inner side wall of the outer cover 10, and an insertion block and a clamping block 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 is in guiding cooperation with the groove wall of the first sliding groove, and the lower surface of the clamping block is in guiding cooperation with the groove wall of the second sliding groove. With the above structure, through the guiding cooperation between the first sliding groove and the insertion block, and the guiding cooperation between the second sliding groove and the clamping block, 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 swinging amplitude of the inner cover 20 during rotation.

[0061] A key and a hook are provided on the outer cover 10. The key is movably arranged vertically, and the hook is movably arranged horizontally. The key can drive the hook to move horizontally. A through groove communicating with the second sliding groove is also provided on the outer cover 10. The hook has a clamping position for clamping and cooperating with the clamping block and an avoidance position for avoiding the clamping block. When the hook is in the avoidance position, the clamping block can move into the second sliding groove through the through groove. When the hook moves to the clamping position, the hook surface of the hook is flush with the groove wall of the second sliding groove and can be in clamping and cooperating with the clamping block. By pressing the key, the hook can be driven to move horizontally, so that the hook moves from the clamping position to the avoidance position. At this time, the clamping block can be installed into the second sliding groove through the through groove, and the insertion block can be installed into the first sliding groove. Then release the key, so that the hook moves from the avoidance position to the clamping position, and the hook can be used to be in clamping and cooperating with the clamping block to realize the limit of the inner cover 20 to prevent the inner cover 20 from falling off the outer cover 10.

[0062] In this embodiment, springs are provided on both the key and the hook, and the restoring force provided by the springs can realize the automatic reset of the key and the hook.

[0063] Among them, since the hook surface of the hook is flush with the groove wall of the second sliding groove, when the inner cover 20 is installed on the outer cover 10, the inner cover 20 is limited and supported by the hook. After the inner cover 20 rotates relative to the outer cover 10, the inner cover 20 is limited and supported by the groove wall of the second sliding groove.

[0064] Specifically, when installing the inner cover 20, the inner cover 20 is inclined relative to the outer cover 10 to insert the insertion block into the first sliding groove, and then the inner cover 20 is pushed. Thus, with the insertion block as the swing point, the inner cover 20 swings towards the direction close to the outer cover 10, so that the clamping block extends into the second sliding groove, thereby installing the inner cover 20 on the outer cover 10. And the inner cover 20 rotates relative to the outer cover 10 under the outer cover 10, and the groove wall of the first sliding groove supports the insertion block, and the groove wall of the second sliding groove supports the clamping block. When the cooking appliance is pressed downwards, the inner cover 20 is pushed to float relative to the outer cover 10. At this time, the insertion block moves upwards in the first sliding groove, and the clamping block moves upwards in the second sliding groove. When disassembling the inner cover 20, the inner cover 20 is pulled, so that with the insertion block as the swing point, the inner cover 20 swings away from the outer cover 10, so that the clamping block disengages from the second sliding groove, and the inner cover 20 is inclined relative to the outer cover 10 to facilitate taking out the insertion block from the first sliding groove.

[0065] Another embodiment of the present utility model provides a cooking appliance, which includes an upper cover assembly and a pot body. The upper cover assembly is openably and closably covered above the pot body, and the upper cover assembly is the upper cover assembly provided above. Since the temperature measuring member 11 and the exhaust pipe 31 are both arranged on the outer cover 10 and are both in sealed cooperation with the inner cover 20. When disassembling the inner cover 20, it is not necessary to disassemble the temperature measuring member 11 and the exhaust pipe 31, thereby simplifying the disassembly steps of the inner cover 20 and making the operation more convenient.

[0066] Among them, the cooking appliance includes an electric pressure cooker and a multifunctional frying pan with a pressure cooking function.

[0069] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Without contrary statements, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be construed as limiting the protection scope of the present utility model; the orientation words "inner, outer" refer to the inside and outside relative to the contour of each component itself.

[0070] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationships of one device or feature to other devices or features as shown in the drawings. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0071] In addition, it should be noted that the use of words such as "first", "second" to limit components is only for the convenience of differentiating the corresponding components. Without additional statements, the above words have no special meanings, and thus cannot be construed as limiting the protection scope of the present utility model.
