Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and in particular to a locking assembly and a cooking utensil having the same. Background Art

[0002] In related art, pressure cooking appliances feature interlocking pot and lid teeth between the pot and lid assemblies to provide pressure during the upper cooking phase. For lid assemblies that flip open, a torsion spring is typically installed between the two assemblies to allow the lid assembly to automatically open if the pot and lid teeth become misaligned. The strong force of the torsion spring can cause the pot and lid teeth to fit together, resulting in significant friction between them during lid opening, making it difficult to operate.

[0003] To avoid the aforementioned problems, a snap-fit ​​structure is provided between the pot body assembly and the lid assembly to prevent the lid teeth from abutting against the pot teeth under the force of the lid-opening torsion spring. Once the lid teeth and pot teeth are completely dislocated, the snap-fit ​​structure is released, allowing the lid assembly to automatically open under the force of the lid-opening torsion spring. Currently, this snap-fit ​​structure is typically released by providing a pressing structure on either the pot body assembly or the lid assembly. Utility Model Content

[0004] The main purpose of the present invention is to provide a locking assembly which is different from a push-locking structure and is easy to operate, and a cooking utensil having the same.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a locking assembly for cooperating with a pot body assembly and a cover body assembly is provided, the locking assembly including: an operating part, which is movably arranged on the pot body assembly; a lock hook part, which is movably arranged on the pot body assembly and has a hook state and an unfastened state, the lock hook part including a snap plate and a first snap hook arranged at the end of the snap plate, when the lock hook part is in the hook state, the first snap hook is engaged with the second snap hook on the cover body assembly, when the lock hook part is in the unfastened state, the first snap hook is separated from the second snap hook, a driving inclined surface is provided on the snap plate, and when the operating part is active, it can push the driving inclined surface to switch the lock hook part from the hook state to the unfastened state.

[0006] The technical solution of the present invention comprises a locking assembly movably mounted on the pot body assembly. The locking assembly comprises a locking plate and a first hook disposed at an end of the locking plate. The locking plate is provided with a driving inclined surface that can be driven by an operating unit to cause the locking plate to move. When the locking plate moves, it can drive the first hook to switch between engaging and disengaging with a second hook on the lid assembly, thereby achieving engagement or disengagement between the lid assembly and the pot body assembly. When closing the lid, the first and second hooks can first engage to overcome the force of the lid opening torsion spring, and then the lid teeth and the pot teeth can be aligned. When opening the lid, the lid teeth and the pot teeth can first be offset, and then the first hook and the second hook can be separated. This effectively ensures smooth position switching of the pot teeth during the lid opening and closing process. Specifically, a user can operate the operating unit to move the operating unit along the extension direction of the driving inclined surface, thereby driving the locking plate to move. The invention has the advantages of simple structure and simple operation.

[0007] Furthermore, the operating portion includes an operating knob rotatably mounted on the pot body assembly, and when the operating knob is rotated, the operating knob pushes the driving inclined surface. The user can switch the lock hook portion from the hooked state to the unlocked state by rotating the operating knob, which has the advantage of easy operation.

[0008] Furthermore, the operating knob includes an operating button and a drive rod connected to the operating button. The drive rod is disposed offset from the rotation center of the operating button, and when the operating button is rotated, the drive rod is capable of pushing against the drive inclined surface. When the user rotates the operating button, the drive rod moves in an arc or circular trajectory. The movement of the drive rod drives the locking plate to move, thereby switching the lock hook portion from the hooked state to the unlocked state.

[0009] Furthermore, the end of the driving rod has a push-up arc surface. The setting of the push-up arc surface can reduce the friction between the driving rod and the driving inclined surface during the movement of the driving rod, so that the user can operate the operating button more smoothly.

[0010] Furthermore, the lock hook portion includes a rotating shaft disposed on the locking plate, and the locking plate is swivellable about the axis of the rotating shaft to switch the lock hook portion between a locked state and an unlocked state. Swinging of the locking plate partially releases the force of the lid-opening torsion spring, reducing the force of the lid-opening torsion spring on the lid assembly when the first and second hooks finally separate, thereby preventing the cooking appliance from shifting or jumping due to excessive force from the lid-opening torsion spring.

[0011] Furthermore, the lock hook portion includes a reset member that applies a reset force to the snap plate to enable the lock hook portion to switch from the unfastened state to the engaged state and remain in the engaged state. The reset member enables the lock hook portion to automatically reset after the user stops operating the operating portion, and the lock hook portion automatically resets to drive the operating portion to reset as well.

[0012] Furthermore, the locking assembly further includes a transmission plate movably mounted on the pot body assembly. The operating knob is capable of driving the transmission plate to move, and when the transmission plate moves, the locking member on the cover assembly is switched between the aligned and misaligned positions. Rotating the operating knob drives the transmission plate to move, thereby switching the locking member between the aligned and misaligned positions. By operating the operating knob, the user can switch the state of both the fastening structure and the locking member, thereby facilitating user operation.

[0013] Furthermore, the transmission plate is provided with a driving groove and an escape groove communicating with the driving groove, and the snap plate is further provided with an escape recess adjacent to the driving inclined surface, the escape recess being provided corresponding to the driving groove, and the escape groove being provided corresponding to the driving inclined surface. The driving rod is located in the driving groove or the escape groove. When the driving rod is located in the driving groove, the transmission plate can be driven to move, and the escape recess avoids the driving rod. When the driving rod is located in the escape groove, the driving rod pushes against the driving inclined surface. The driving rod sequentially drives the transmission plate and the snap plate to move, thereby achieving step-by-step unlocking and locking of the lock hook portion and the locking member, simplifying the structure of the operating knob.

[0014] Furthermore, the locking assembly further includes a first transmission post, a second transmission post, and a transmission rocker. The first transmission post is disposed on the pot body assembly and engages with a transmission plate for driving. When the transmission plate moves, it drives the first transmission post to rotate. The second transmission post is disposed on the cover assembly and engages with the first transmission post for rotation. When the first transmission post rotates, it drives the second transmission post to rotate synchronously. The transmission rocker is disposed on the cover assembly and connected between the second transmission post and the locking member. When the second transmission post rotates, it drives the transmission rocker to swing, thereby driving the locking member to switch between the aligned and misaligned positions. By disposing the transmission plate, the first transmission post, the second transmission post, and the transmission rocker between the operating portion and the locking member, the driving force of the operating portion can be transmitted from the pot body assembly to the cover assembly, thereby enabling the operating portion that drives the locking member to switch its state to be disposed on the pot body assembly. This leaves the entire upper portion of the cover assembly free for a larger operating panel or other structure, thereby improving the user experience.

[0015] According to another aspect of the present invention, a cooking appliance is provided, comprising a pot body assembly, a lid assembly, and a locking assembly, wherein the locking assembly is the aforementioned locking assembly. The aforementioned locking assembly engages with the lid assembly through a pressing operation different from that of a press-locking structure, and has the advantage of a simple structure. The cooking appliance incorporating the aforementioned locking assembly also has the aforementioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0042] like Figures 1 to 5 As shown, the present application provides a locking assembly that is different from a push-lock structure and is simple to operate. The locking assembly is used to cooperate with the pot body assembly 20 and the cover body assembly 40. The embodiment of the assembly of the present application includes an operating portion 10 and a lock hook portion 30. The operating portion 10 is movably disposed on the pot body assembly 20; the lock hook portion 30 is movably disposed on the pot body assembly 20 and has a hook state and an unhooked state. The lock hook portion 30 includes a locking plate 31 and a first hook 32 disposed at the end of the locking plate 31. When the lock hook portion 30 is in the hook state, the first hook 32 is engaged with a second hook on the cover body assembly 40. When the lock hook portion 30 is in the unhooked state, the first hook 32 is separated from the second hook. The locking plate 31 is provided with a driving inclined surface 311. When the operating portion 10 is movable, it can push against the driving inclined surface 311 to switch the lock hook portion 30 from the hook state to the unhooked state.

[0043] The locking assembly 30 includes a locking hook portion 30 movably provided on the pot body assembly 20, the locking hook portion 30 including a locking plate 31 and a first hook 32 provided at an end of the locking plate 31. The locking plate 31 is provided with a driving inclined surface 311 which can be driven by the operating part 10 to make the locking plate 31 move. When the locking plate 31 moves, it can drive the first hook 32 to switch between a state of engagement with or separation from the second hook on the lid assembly 40, thereby achieving engagement or disengagement between the lid assembly 40 and the pot body assembly 20. When closing the lid, the first hook 32 and the second hook can be engaged to overcome the force of the lid opening torsion spring, and then the lid teeth 422 are aligned with the pot teeth 251. When opening the lid, the lid teeth 422 and the pot teeth 251 can be offset first, and then the first hook 32 is separated from the second hook, which can effectively ensure the smoothness of the pot teeth in switching positions during the lid opening and closing process. Specifically, the user can operate the operating portion 10 to move the operating portion 10 along the extension direction of the driving inclined surface 311, thereby driving the locking plate 31 to move, which has the advantages of simple structure and simple operation.

[0044] like Figures 1 to 5 As shown, the operating portion 10 includes an operating knob 11, which is rotatably disposed on the pot body assembly 20. When the operating knob 11 is rotated, it can push the driving inclined surface 311. The user can switch the lock hook portion 30 from the hook state to the unlocked state by rotating the operating knob 11, which has the advantage of easy operation.

[0045] like Figures 1 to 5 As shown, the operating knob 11 includes an operating button 111 and a driving rod 112 connected to the operating button 111. The driving rod 112 is arranged offset from the rotation center of the operating button 111. When the operating button 111 is rotated, the driving rod 112 can push against the driving inclined surface 311. The driving rod 112 is arranged offset from the rotation center of the operating button 111. When the user rotates the operating button 111, the driving rod 112 moves in an arc or circular trajectory. The movement component of the driving rod 112 drives the locking plate 31 to move, thereby switching the lock hook portion 30 from the hooked state to the unlocked state.

[0046] like Figures 3 and 4As shown, the operating button 111 includes a first rotary disk 1111 and a second rotary disk 1112, which are separately arranged. The pot body assembly 20 includes a mounting base 24 for mounting the operating knob 11. The first rotary disk 1111 is arranged on the outside of the mounting base 24, and the second rotary disk 1112 is arranged on the inside of the mounting base 24. The circumferential sidewall of the first rotary disk 1111 is provided with anti-slip grooves to facilitate the user's grip. The inside of the first rotary disk 1111 is also provided with a connecting tube 1113 that penetrates the mounting base 24. The inside of the connecting tube 1113 has an insertion groove. The outside of the second rotary disk 1112 is provided with a connecting block 1114 that can be inserted into the insertion groove to achieve a rotation-proof connection between the first rotary disk 1111 and the second rotary disk 1112. The driving rod 112 is provided on the inner surface of the second rotary disk 1112.

[0047] like Figure 4 and Figure 5 As shown, the end of the driving rod 112 has a push-up arc surface 1121. The setting of the push-up arc surface 1121 can reduce the friction between the driving rod 112 and the driving inclined surface 311 during the movement, so that the user can operate the operating button 111 more smoothly.

[0048] like Figure 1 and Figure 2 As shown, the lock hook portion 30 also includes a rotating shaft 33 disposed on the locking plate 31. The locking plate 31 is oscillating about the axis of the rotating shaft 33 to switch the lock hook portion 30 between a locked and unlocked state. The locking plate 31 is configured as a swinging member. When the locking plate 31 swings under the drive rod 112, the first hook 32 moves in an arc. During this process, the lid assembly 40 opens slightly under the action of the lid-opening torsion spring, partially releasing the force of the lid-opening torsion spring. This reduces the force of the lid-opening torsion spring on the lid assembly when the first hook 32 and the second hook finally separate, thus preventing the cooking appliance from shifting or jumping due to excessive force from the lid-opening torsion spring. The driving rod 112 moves in an arc or circular motion, and the movement of the locking plate 31 through the movement component of its motion trajectory can further mitigate the release of the force of the lid-opening torsion spring.

[0049] like Figure 3 As shown, the lock hook portion 30 includes two rotating shafts 33 arranged on two opposite sides of the buckling plate 31, and the two rotating shafts 33 are respectively inserted into two second mounting holes 233 on two mounting plates 232 provided on the middle plate 23.

[0050] In this embodiment, the lock hook portion 30 further includes a reset member that applies a reset force to the snap plate 31, thereby enabling the lock hook portion 30 to switch from the unfastened state to the engaged state and remain in the engaged state. The lock hook portion 30 can remain in the engaged state under the force of the reset member, enabling the lock hook portion 30 to automatically reset after the user stops operating the operating portion 10. The lock hook portion 30 automatically resets, and the operating portion 10 can also be reset when the lock hook portion 30 automatically resets.

[0051] Specifically, in this embodiment, the reset member is a torsion spring structure, which applies a pushing force toward the outside of the pot body assembly 20 to the lower end of the buckle plate 31, so that the lock hook portion 30 can be kept in the hooked state.

[0052] like Figure 2 As shown, a guiding slope is provided on the first hook 32. When the cover assembly 40 is closed onto the pot body assembly 20, the second hook on the cover assembly 40 cooperates with the guiding slope and pushes the first hook 32 outward to drive the locking plate 31 to swing, so that the lock hook portion 30 switches from the hooked state to the unfastened state. After the second hook passes over the first hook 32, the lock hook portion 30 switches from the unfastened state to the hooked state under the action of the reset member. The above structure realizes the automatic fastening between the first hook 32 and the second hook during the closing process. The user does not need to perform any operations other than pressing down the cover assembly 40, which is convenient for the user.

[0053] like Figure 1 、 Figure 2 、 Figure 10 and Figure 12 As shown, the locking assembly further includes a transmission plate 50 movably mounted on the pot body assembly 20. The operating knob 11 is capable of driving the transmission plate 50 to move. When the transmission plate 50 moves, it can drive the locking member 42 on the cover body assembly 40 to switch between the aligned position and the misaligned position. When the operating knob 11 is rotated, it can drive the transmission plate 50 to move, thereby driving the locking member 42 to switch between the aligned position and the misaligned position. By operating the operating knob 11, the user can switch the state of both the snap-fit ​​structure and the state of the locking member 42, eliminating the need for the user to operate different operating members on the cover body assembly and the pot body assembly to switch the state of the two structures, thereby facilitating user use.

[0054] like Figure 1 、 Figure 2 and Figure 6As shown, the transmission plate 50 is provided with a driving groove 51 and an avoidance groove 52 connected to the driving groove 51, and the locking plate 31 is also provided with an avoidance recess 312 adjacent to the driving inclined surface 311. The avoidance recess 312 is arranged corresponding to the driving groove 51, and the avoidance groove 52 is arranged corresponding to the driving inclined surface 311. The driving rod 112 is located in the driving groove 51 or the avoidance groove 52. When the driving rod 112 is located in the driving groove 51, it can drive the transmission plate 50 to move and the avoidance recess 312 avoids the driving rod 112. When the driving rod 112 is located in the avoidance groove 52, the driving rod 112 pushes the driving inclined surface 311. Specifically, in this embodiment, the avoidance recess 312 and the driving inclined surface 311 are disposed adjacent to each other in the vertical direction, and the driving groove 51 and the avoidance groove 52 are disposed adjacent to each other and in communication in the vertical direction. When the driving rod 112 is located in the driving groove 51, the driving rod 112 can abut against the vertical groove wall of the driving groove 51, thereby driving the transmission plate 50 to move in the lateral direction. The avoidance recess 312 avoids the driving rod 112, so that the driving rod 112 cannot cause the locking plate 31 to swing. When the driving rod 112 is located in the avoidance groove 52, the avoidance groove 52 avoids the driving rod 112, so that the driving rod 112 cannot cause the transmission plate 50 to move. The driving rod 112 abuts against the driving inclined surface 311 and causes the locking plate 31 to swing. The driving rod 112 sequentially drives the transmission plate 50 and the locking plate 31 to move, thereby achieving step-by-step unlocking and locking of the lock hook portion 30 and the locking member 42, simplifying the structure of the operating knob 11.

[0055] like Figure 1 、 Figures 6 to 10 as well as Figure 12 As shown, the locking assembly also includes a first transmission column 60, a second transmission column 70 and a transmission rocker 80. The first transmission column 60 is arranged on the pot body assembly 20 and is driven by the transmission plate 50. When the transmission plate 50 moves, it drives the first transmission column 60 to rotate. The second transmission column 70 is arranged on the cover body assembly 40 and is stopped by the first transmission column 60. When the first transmission column 60 rotates, it drives the second transmission column 70 to rotate synchronously. The transmission rocker 80 is arranged on the cover body assembly 40 and is connected between the second transmission column 70 and the locking member 42. When the second transmission column 70 rotates, it drives the transmission rocker 80 to swing and thereby drives the locking member 42 to switch between the tooth-matching position and the tooth-mismatching position. By arranging a transmission plate 50, a first transmission column 60, a second transmission column 70 and a transmission rocker 80 between the operating part 10 and the locking part 42, the driving force of the operating part 10 can be transmitted from the pot body assembly 20 to the cover body assembly 40, thereby achieving the operation part 10 that drives the locking part 42 to switch the state to be arranged on the pot body assembly 20. That is, there is no need to arrange an operating part for driving the locking part 42 to switch the state on the cover body assembly 40, so that the upper part of the cover body assembly 40 can be completely left empty for arranging a larger operating panel or other structure, thereby improving the user experience.

[0056] like Figure 6 and Figure 7 As shown, the upper end of the transmission plate 50 is provided with drive spur teeth, which include a plurality of first drive teeth 53. The first transmission column 60 includes a first coupling column 61 and a first gear 62, which are connected to each other in a rotationally fixed manner. The first gear 62 meshes with the drive spur teeth. The first gear 62 is provided with a plurality of first driven teeth 621. The cooperation between the first gear 62 and the drive spur teeth enables the first gear 62 and the first coupling column 61 to rotate when the transmission plate 50 moves. The transmission plate 50 is also provided with a guide slot 54. The guide column 234 provided on the middle plate 23 is inserted into the guide slot 54 to guide the movement of the transmission plate 50.

[0057] like Figure 7 、 Figure 8 and Figure 12 As shown, the first transmission column 60 includes a first coupling column 61 disposed above the middle plate 23 and engaging with the stopper of the middle plate 23, and a first gear 62 disposed below the middle plate 23 and engaging with the stopper of the middle plate 23. The second transmission column 70 includes a second coupling column 71 disposed below the lining cover 43 and engaging with the stopper of the lining cover 43, and a second gear 72 disposed above the lining cover 43 and engaging with the stopper of the lining cover 43. The first coupling column 61 and the second coupling column 71 can be rotationally coupled to achieve synchronous rotation of the first transmission column 60 and the second transmission column 70. Specifically, the first coupling column 61 is provided with a coupling groove 611 with an open upper end, and the lower end of the second coupling column 71 is provided with a coupling block 711 that plugs and engages with the coupling groove 611.

[0058] like Figure 1 、 Figure 7 and Figure 9 As shown, the second transmission column 70 includes a second gear 72, the second gear 72 includes a plurality of second driving teeth 721, and the transmission rocker 80 is provided with a driven arc tooth meshing with the second gear 72, the driven arc tooth includes a plurality of second driven teeth 81, and the transmission rocker 80 is provided with a rotating shaft hole 83 at one end away from the driven arc tooth. The mounting column on the lining cover 43 is passed through the rotating shaft hole 83. Through the cooperation between the driven arc tooth and the second gear 72, the second transmission column 70 is driven to drive the transmission rocker 80 to swing around the central axis of the rotating shaft hole 83 when it rotates.

[0059] like Figures 9 to 11 As shown, a driving groove 82 is also provided on the transmission rocker 80, and the transmission rod 423 on the locking member 42 is inserted into the driving groove 82. When the transmission rocker 80 swings, it drives the locking member 42 to move, thereby realizing the position switching of the locking member 42.

[0060] like Figures 10 to 13As shown, the present application also provides a cooking utensil comprising a pot body assembly 20, a lid assembly 40, and a locking assembly, wherein the locking assembly is the aforementioned locking assembly. The aforementioned locking assembly is engaged with the lid assembly 40 by a pressing operation different from that of the press-locking structure, and has the advantage of a simple structure. The cooking utensil having the aforementioned locking assembly also has the aforementioned advantages.

[0061] like Figure 10 As shown, the pot assembly 20 includes an outer shell 21, a bottom shell 22 disposed below the outer shell 21, a middle plate 23 disposed above the outer shell 21, and a pot body 25 disposed within the outer shell 21. The outer shell 21 is provided with an installation opening 211 for mounting the operating unit 10, and the mounting base 24 is mounted at the installation opening 211. The upper end of the pot body 25 is provided with pot teeth 251 that can be engaged with the cover teeth 422 on the locking member 42.

[0062] like Figure 13 As shown, the middle plate 23 is provided with a first mounting hole 231, and the first transmission column 60 is passed through the first mounting hole 231. Two mounting plates 232 are respectively located on both sides of the first mounting hole 231. Two guide columns 234 are further provided below the middle plate 23 to guide the movement of the transmission plate 50.

[0063] like Figure 10 and Figure 11 As shown, the cover assembly 40 includes a surface cover 44, a lining cover 43 and a locking member 42 arranged in sequence from top to bottom. The locking member 42 includes a locking cover 421, a cover tooth 422 arranged on the outer periphery of the locking cover 421 and a transmission rod 423 arranged above the locking cover 421. The locking cover 421 is rotatably arranged, and the transmission rod 423 passes upward through the lining cover 43 and extends into the driving groove 82 on the transmission rocker 80, so that the locking cover 421 is driven to rotate when the transmission rocker 80 swings, thereby driving the cover tooth 422 to switch between a position opposite to the pot tooth 251 and a position offset from the pot tooth 251.

[0064] In this embodiment, the locking member 42 is a rotatably arranged locking cover 421; in an embodiment not shown in the figure, the locking member can also be a caliper structure that performs translational motion to switch between the tooth-aligning position and the tooth-misaligning position.

[0065] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0066] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0067] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
