Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and in particular to a driving component, a pot body component and a cooking utensil. Background Art

[0002] In the related art, a double lock is generally provided between the lid assembly and the pot body assembly of the pressure cooking appliance, wherein one lock is between the pot teeth and the lid teeth, and the other lock is between the hook structures.

[0003] For pressure cooking appliances that flip open the lid, a lid-opening torsion spring is generally provided at the hinged position of the lid assembly and the pot body assembly to apply a force to flip open the lid to the lid assembly and to enable the lid assembly to remain in the open state after opening.

[0004] Due to the presence of the lid-opening torsion spring, the dual locking between the lid and pot assembly requires a specific sequence for both locking and unlocking. Specifically, when closing the lid, the hook mechanism first locks, followed by the locking mechanism between the pot and lid teeth. When opening the lid, the two teeth first unlock, followed by the hook mechanism. Therefore, the user must perform two operations to open the lid: the first to unlock the pot and lid teeth, and the second to unlock the hook mechanism. This makes the lid-opening operation cumbersome and impacts the user experience. Utility Model Content

[0005] The main purpose of the utility model is to provide a driving assembly, a pot body assembly and a cooking utensil to solve the problem in the related art that the user needs to perform two operations when opening the lid.

[0006] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a drive assembly is provided, which is used to be arranged on the shell of the pot body assembly, wherein the drive assembly includes: an operating member, which is movably or rotatably arranged relative to the shell, and the operating member has an operating part and a transmission part; a driving member, which has a matching groove, and the transmission part extends into the matching groove, and the matching groove has a linkage groove section and an avoidance groove section. When the transmission part is located in the linkage groove section, the operating member drives the driving member to move when it is actuated, and when the transmission part is located in the avoidance groove section, the operating member can continue to act and the driving member remains stationary.

[0007] According to the technical solution of the present invention, a drive assembly is mounted on the housing of the pot assembly and is capable of rotating the locking cover of the lid assembly and disengaging the hook structure of the pot assembly. The drive assembly includes an operating member and a driver. To open the lid, the user can operate the operating member to move the driver, thereby performing both the unthreading and unthreading operations. Specifically, the operating member includes an operating portion and a transmission portion. The transmission portion extends into a mating slot on the driver and drives the driver to move. The mating slot includes a linkage slot section and a relief slot section. When the transmission portion is within the linkage slot section, the operating member moves the driver together, enabling unthreading. After the unthreading operation is complete, the transmission portion extends into the relief slot section. The relief slot section relieves the transmission portion's movement, allowing the operating member to continue moving without the driver moving synchronously with the operating member. The unthreading operation can then be performed by the operating member. In this process, the user only needs to move or rotate the operating member to first unthread and then unthread, simplifying the operation and improving the user experience. Therefore, the technical solution of the present application can effectively solve the problem in the related art that the user needs to perform two operations when opening the cover.

[0008] Furthermore, the operating portion includes an operating knob, and the transmission portion includes a transmission rod disposed on the operating knob. The transmission rod is disposed offset from the center of the operating knob and is capable of rotating within adjacent first and second rotational regions. When the transmission rod rotates within the first rotational region, the transmission rod is located within the linkage groove section and abuts against the sidewall of the linkage groove section, thereby driving the driving member to move. When the transmission rod rotates within the second rotational region, the transmission rod is located within the avoidance groove section and is separated from the sidewall of the avoidance groove section. The transmission rod is disposed offset from the center of the operating knob. When the operating knob is rotated, the transmission rod rotates along an arcuate or circular trajectory, thereby causing the transmission rod to have motion components in the up-down and left-right directions. The transmission rod is disposed within the mating groove, enabling the driving member to move along with the transmission rod.

[0009] According to another aspect of the present invention, a pot body assembly is provided, comprising a housing, a drive assembly and a hook structure disposed on the housing. The drive assembly is the aforementioned drive assembly, and the hook structure is movably disposed on the housing and has a hooked state and an unlocked state. When a transmission portion is located within the escape groove, the transmission portion engages with the hook structure and drives the hook structure from the hooked state to the unlocked state. The aforementioned drive assembly effectively resolves the problem in the related art of requiring users to perform two operations to open the lid. A pot body assembly incorporating the aforementioned drive assembly also has the aforementioned advantages.

[0010] Furthermore, the hook structure has an escape zone corresponding to the linkage slot section and a matching slope corresponding to the escape zone. The matching slope extends toward the transmission portion in a direction away from the escape zone. When the transmission portion is located within the linkage slot section, the hook structure remains in a hooked state. When the transmission portion moves within the escape zone in a direction away from the linkage slot section, the transmission portion abuts against the matching slope and drives the hook structure from the hooked state to the unlocked state. The above-mentioned structure allows the transmission portion to perform the stripping and release operations in steps, so that the transmission portion can first strip the teeth and then release the gear in a single action.

[0011] According to another aspect of the present invention, a pot body assembly is provided, comprising a housing, a drive assembly and a mounting base disposed on the housing, wherein the drive assembly is the aforementioned drive assembly, the housing is provided with a mounting hole, the mounting base is disposed at the mounting hole, an operating member is disposed through the mounting base, the mounting base is provided with an arcuate groove, and a transmission rod is disposed within the arcuate groove. The arcuate groove on the mounting base can guide the movement of the transmission rod and limit the transmission rod to an extreme position.

[0012] Furthermore, the arcuate groove has a first arcuate segment corresponding to the first rotational region and a second arcuate segment corresponding to the second rotational region. The pot body assembly also includes a first return member disposed between the mounting base and the operating member. When the transmission rod is located within the first arcuate segment, the return member separates from the transmission rod. When the transmission rod is located within the second arcuate segment, the first return member applies a return force to the transmission rod to cause the transmission rod to rotate into the first arcuate segment. When the lid opening operation is completed and the user no longer operates the operating member, the transmission rod located within the second arcuate segment is moved back into the first arcuate segment under the action of the first return member. Since the transmission rod no longer abuts the mating inclined surface, the hook structure returns to the hooked state. When the user subsequently closes the lid, the hook structure can automatically engage with the fixed hook on the lid body assembly.

[0013] Furthermore, the first return element is a torsion spring. The mounting seat is provided with a mounting recess that is sunken toward the inside of the pot body assembly. The mounting recess includes a central mounting area located in the middle of the mounting seat and a return mounting area located outside the central mounting area and connected to the second arc segment. The mounting recess has a first sidewall distal to the second arc segment and a second sidewall proximal to the second arc segment. The torsion spring includes a torsion spring body and first and second torsion arms disposed at opposite ends of the torsion spring body. The torsion spring body is located within the central mounting area. When the transmission rod is located within the first arc segment, the first torsion arm abuts against the first sidewall, and the second torsion arm abuts against the second sidewall. When the transmission rod is located within the second arc segment, the first torsion arm abuts against the first sidewall, and the second torsion arm abuts against the transmission rod. The mounting recess provides mounting space for the torsion spring. When the transmission rod moves into the second arc segment, the second torsion arm applies a return force to the transmission rod, enabling the transmission rod to return to the first arc segment, thereby preventing interference with the automatic fastening function of the hook structure.

[0014] Furthermore, the pot body assembly further includes a locking member, which is movably disposed on the housing in an up-down direction and is exposed upward from the housing. The locking member has an unlocked position and a locked position. When the locking member is subjected to downward pressure, it can switch from the locked position to the unlocked position. When the locking member is in the unlocked position, the driving member can move. When the locking member is in the locked position, the locking member and the driving member are locked and engaged. When the locking member is not subjected to downward pressure, the locking member locks the driving member, facilitating alignment between the driving member and a corresponding structure on the lid assembly when the user closes the lid.

[0015] Furthermore, the locking member includes a trigger portion, a locking portion, and a second reset portion. The trigger portion extends upward from the housing, the locking portion is located below the trigger portion and can be locked with the driving member, and the second reset portion applies an upward force to the trigger portion and / or the locking portion to keep the locking member in the locked position; and / or the locking member includes a lock hook, the lock hook has a lock slot opening upward, and a locking rod is provided on the driving member. When the locking member is in the unlocked position, the locking rod is located above the lock slot, and when the locking member is in the locked position, the locking rod is located in the lock slot. The second reset portion can apply an upward force to the trigger portion and / or the locking portion, so that the locking member remains in the locked position and the locking portion locks the driving member; the trigger portion can be triggered by the cover assembly to move downward so that the locking member moves from the locked position to the unlocked position. The locking of the driving member is achieved by the lock hook with the lock slot cooperating with the locking rod, which has the advantages of simple structure and reliable locking.

[0016] According to another aspect of the present invention, a cooking utensil is provided, comprising a pot body assembly and a cover assembly that is openably and closably disposed over the pot body assembly, wherein the pot body assembly is the pot body assembly described above, wherein the cover assembly comprises a mounting cover, a locking member movably disposed on the mounting cover, and a swinging member disposed on the mounting cover, wherein a driving member is capable of drivingly cooperating with the swinging member and driving the swinging member to swing, and when the swinging member swings, the locking member switches between a locked position and a circumventing position. When the driving member moves laterally, the swinging member is driven to swing, thereby achieving rotation of the locking cover through the swinging member, thereby achieving the advantage of a simple structure.

[0017] Furthermore, the swinging member includes a swinging rod, a rotating portion disposed at one end of the swinging rod, and a drive-cooperating portion disposed at the other end of the swinging rod. The driving member can cooperate with the drive-cooperating portion to drive the swinging member to swing about the rotating portion. Alternatively, the cooking appliance further includes a transmission assembly rotatably disposed between the driving member and the swinging member. When the driving member moves, the transmission assembly rotates, and the transmission assembly cooperates with the swinging member to drive the swinging member to swing. The driving member cooperates with the drive-cooperating portion to cause the swinging member to swing about the center of the rotating portion, thereby enabling the locking member to switch positions. By providing the transmission assembly, the movement of the driving member is converted into the swinging portion's swinging, thereby transmitting the driving force on the pot assembly to the lid assembly. Specifically, by providing the driving assembly on the pot assembly, the space above the lid assembly can be freed up to accommodate a larger control panel, thereby enhancing the user experience.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. 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.

[0051] like Figures 1 to 3 As shown, the present application provides a driving assembly for being arranged on the shell 10 of the pot body assembly. An embodiment of the driving assembly of the present application includes an operating member 20 and a driving member 30, wherein the operating member 20 is movably or rotatably arranged relative to the shell 10, and the operating member 20 has an operating part 21 and a transmission part 22; the driving member 30 has a matching groove 31, and the transmission part 22 extends into the matching groove 31, and the matching groove 31 has a linkage groove section 311 and an avoidance groove section 312. When the transmission part 22 is located in the linkage groove section 311, the operating member 20 drives the driving member 30 to move when it is actuated. When the transmission part 22 is located in the avoidance groove section 312, the operating member 20 can continue to actuate and the driving member 30 remains stationary.

[0052] Using the technical solution of this embodiment, a drive assembly is mounted on the housing 10 of the pot assembly and is capable of shifting the locking member 90 of the lid assembly and disengaging the hook structure 40 of the pot assembly. The drive assembly includes an operating member 20 and a driving member 30. To open the lid, the user manipulates the operating member 20 to move the driving member 30, thereby performing both the thread removal and the release operation. Specifically, the operating member 20 includes an operating portion 21 and a transmission portion 22. The transmission portion 22 extends into a mating slot 31 on the driving member 30 and drives the driving member 30 to move. The matching groove 31 includes a linkage groove section 311 and an avoidance groove section 312. When the transmission part 22 is located in the linkage groove section 311, the operating member 20 drives the driving member 30 to move together, thereby realizing the tooth removal operation. After the tooth removal operation is completed, the transmission part 22 extends into the avoidance groove section 312. The avoidance groove section 312 can avoid the movement of the transmission part 22, so that the operating member 20 can continue to move, and the driving member 30 will not move synchronously with the operating member 20. At this time, the operating member 20 can realize the tripping operation. In the above process, the user only needs to move or rotate the operating member 20 to realize the tooth removal first and then the tripping, which simplifies the user's operation and improves the user experience. Therefore, the technical solution of this embodiment can effectively solve the problem in the related art that the user needs to perform two operations when opening the cover.

[0053] like Figures 1 to 3 as well as Figure 11 As shown, the operating portion 21 includes an operating knob 211, and the transmission portion 22 includes a transmission rod 221 provided on the operating knob 211. The transmission rod 221 is provided offset from the center of the operating knob 211. The transmission rod 221 can rotate within a first rotation area a and a second rotation area b that are adjacently provided. When the transmission rod 221 is in the first rotation area a (as shown in FIG. Figure 11 As shown, when the first rotation area a rotates in the area between the first straight line l1 and the second straight line l2, the transmission rod 221 is located in the linkage groove section 311 and abuts against the side wall of the linkage groove section 311 to drive the driving member 30 to move. When the transmission rod 221 rotates in the second rotation area b (as shown in FIG. Figure 11 As shown, when the transmission rod 221 rotates within the second rotation area (b) (the area between the first straight line l1 and the third straight line l3), it is located within the avoidance groove section 312 and separated from the sidewalls of the avoidance groove section 312. The transmission rod 221 is offset from the center of the operating knob 211. When the operating knob 211 is rotated, the transmission rod 221 rotates along an arc or circular trajectory, resulting in the transmission rod 221 having motion components in the vertical direction and the left-right direction. The transmission rod 221 is inserted into the mating groove 31, allowing the driving member 30 to move with the transmission rod 221.

[0054] Specifically, if Figure 1 and Figure 3 As shown, the matching groove 31 is a long groove structure extending vertically, and the avoidance groove section 312 is located below the linkage groove section 311. The width of the linkage groove section 311 is equivalent to the diameter of the transmission rod 221. The long groove can avoid the movement of the transmission rod 221 in the up and down directions, and the movement of the transmission rod 221 in the left and right directions drives the driving member 30 to move together; the avoidance groove section 312 has an arc-shaped side wall. When the transmission rod 221 moves into the avoidance groove section 312, the avoidance groove section 312 avoids the movement of the transmission rod 221 in the up and down directions and the left and right directions, so that the operating member 20 can continue to rotate and the driving member 30 remains stationary.

[0055] like Figure 3 As shown, in this embodiment, the avoidance groove section 312 is provided at the lower end of the linkage groove section 311 and is surrounded by a section of arc-shaped wall. In an embodiment not shown in the figure, the avoidance groove section can also be an arc-shaped groove adapted to the motion trajectory of the transmission rod.

[0056] In this embodiment, the operating member 20 is a rotating member, and the driving member 30 is a translating member. In an embodiment not shown in the figures, both the operating member and the driving member can be movable members. Specifically, the operating portion of the operating member is a push button structure. The user pushes the push button to push the operating member along an "L"-shaped trajectory. The mating groove on the driving member is a long groove structure extending in the vertical direction. When the lid needs to be opened, the user first pushes the push button along the horizontal section of the "L"-shaped trajectory. At this time, the operating member can drive the driving member to move synchronously. Then, the user pushes the push button along the vertical section of the "L"-shaped trajectory. At this time, the operating member can continue to move while the driving member remains stationary.

[0057] like Figures 4 to 11 As shown, the present application also provides a pot body assembly. An embodiment of the pot body assembly of the present application includes a housing 10, a drive assembly and a hook structure 40 disposed on the housing 10. The drive assembly is the drive assembly described above, and the hook structure 40 is movably disposed on the housing 10 and has a hook state and an unlocked state. When the transmission part 22 is located within the avoidance groove section 312, the transmission part 22 can cooperate with the hook structure 40 and drive the hook structure 40 to switch from the hook state to the unlocked state. The above-mentioned drive assembly can effectively solve the problem in the related art that the user needs to perform two operations when opening the lid. The pot body assembly with the above-mentioned drive assembly also has the above-mentioned advantages.

[0058] like Figure 4 As shown, the housing 10 includes an outer shell 12, a middle plate 13 disposed above the outer shell 12, and a bottom shell 14 disposed below the outer shell 12. The pot assembly further includes a pot body 120 disposed in the housing 10.

[0059] like Figure 3 and Figure 6As shown, a second guide post 135 is provided below the middle plate 13, and a guide slot 33 extending in the transverse direction is provided on the driving member 30. The second guide post 135 is provided from top to bottom within the guide slot 33 to guide the movement of the driving member 30. In this embodiment, there are two second guide posts 135 and two guide slots 33, and the two second guide posts 135 and the two guide slots 33 correspond to each other.

[0060] Specifically, the hook structure 40 can cooperate with the fixed hook on the cover assembly. When the hook structure 40 is in the hooked state, the hook structure 40 and the fixed hook on the cover assembly are hooked and engaged, so that the cover assembly can be kept in the fastened state. When the hook structure 40 is in the unlocked state, the hook structure 40 and the fixed hook on the cover assembly are unlocked, and the cover can be opened. When the transmission part 22 is located in the avoidance groove section 312, the transmission part 22 drives and cooperates with the hook structure 40 and drives the hook structure 40 to switch from the hooked state to the unlocked state, thereby opening the cover assembly.

[0061] like Figure 5 、 Figure 8 and Figure 9 As shown, the hook structure 40 has an avoidance area 401 corresponding to the linkage groove section 311 and a matching bevel 402 corresponding to the avoidance groove section 312. In the direction away from the avoidance area 401, the matching bevel 402 extends toward the transmission part 22. When the transmission part 22 is located in the linkage groove section 311, the hook structure 40 remains in the hooked state. When the transmission part 22 moves in the avoidance groove section 312 in the direction away from the linkage groove section 311, the transmission part 22 pushes against the matching bevel 402 and drives the hook structure 40 to switch from the hooked state to the unlocked state. The avoidance area 401 is configured to correspond to the linkage groove section 311. That is, when the transmission part 22 is located in the linkage groove section 311, the transmission part 22 and the driving member 30 drive and cooperate to drive the driving member 30 to move. The transmission part 22 is configured to correspond to the avoidance area 401 and cannot drive the hook structure 40. At this time, the thread removal operation can be performed, and the hook structure 40 remains in the hooked state. The matching inclined surface 402 corresponds to the avoidance groove section 312. That is, when the transmission part 22 is located in the avoidance groove section 312, the transmission part 22 and the matching inclined surface 402 drive and cooperate to drive the hook structure 40 to switch states. The transmission part 22 cannot drive the driving member 30 to move. At this time, the release operation can be performed. That is, the configuration of the above structure enables the transmission part 22 to perform the thread removal operation and the release operation in steps, so that the transmission part 22 can achieve thread removal and release operation by only performing one action.

[0062] like Figure 8As shown, the hook structure 40 is a swinging member, and the hook structure 40 includes a push top portion 41, a rotating shaft portion 42, and a hook body portion 43. The push top portion 41 and the hook body portion 43 are respectively arranged on both sides of the rotating shaft portion 42. Two mounting plates are provided on the middle plate 13 of the shell 10, and the two mounting plates are respectively provided with fixing holes 136. The two ends of the rotating shaft portion 42 are respectively passed through the two fixing holes 136, so that the hook structure 40 swings around the rotating shaft portion 42. The hook body portion 43 is located on the upper side of the rotating shaft portion 42 and can pass upward through the middle plate 13 and engage with the fixed hook on the cover assembly. The push top portion 41 is provided on the lower side of the rotating shaft portion 42, and the avoidance area 401 and the mating inclined surface 402 are both formed on the push top portion 41.

[0063] like Figure 9 and Figure 12 As shown, in this embodiment, the hook structure 40, the driving member 30 and the operating member 20 are arranged in sequence from the inside to the outside of the pot body assembly, the matching groove 31 is a through groove, and the transmission rod 221 extends from the outside of the matching groove 31 to the inside of the matching groove 31 and matches with the hook structure 40.

[0064] In this embodiment, the pot body assembly also includes an elastic member arranged between the shell 10 and the hook structure 40. The elastic member applies a force to the hook structure 40 so that the hook structure 40 remains in the hooked state, that is, the hook structure 40 always remains in the hooked state in the natural state. When the user drives the hook structure 40 through the operating member 20, the hook structure 40 overcomes the force of the elastic member and switches from the hooked state to the unlocked state.

[0065] A guiding slope is provided on the hook body of at least one of the hook structure 40 and the fixed hook on the cover assembly, so that when the cover assembly is pressed downward toward the pot body assembly, under the action of the guiding slope, the hook structure 40 overcomes the elastic force of the elastic member and switches from the hook state to the unlocked state; when the hook body of the fixed hook on the cover assembly passes over the hook body 43 of the hook structure 40, the hook structure 40 switches from the unlocked state to the hook state under the action of the elastic member, thereby realizing automatic fastening between the hook structure 40 and the fixed hook on the cover assembly.

[0066] like Figure 4 、 Figure 10 and Figure 11 As shown, the pot body assembly includes a housing 10, a drive assembly and a mounting base 50 disposed on the housing 10. The housing 10 is provided with a mounting hole 11, and the mounting base 50 is disposed at the mounting hole 11. The operating member 20 is disposed through the mounting base 50. The mounting base 50 is provided with an arcuate groove 51, and the transmission rod 221 is disposed within the arcuate groove 51. The arcuate groove 51 on the mounting base 50 can guide the movement of the transmission rod 221 and limit the extreme position.

[0067] Preferably, the central angle of the arc groove 51 is less than or equal to 180°, that is, the user can perform the tooth removal operation and the tripping operation successively by rotating the operating member 20 at most 180°, so that the user only needs to make one rotation, which further facilitates the user's use and improves the user experience.

[0068] like Figure 4 As shown, the mounting hole 11 is provided on the housing 12 , and the mounting seat 50 is mounted on the mounting hole 11 through a snap-fit ​​structure.

[0069] like Figure 4 and, Figure 10 and Figure 11 As shown, the arcuate groove 51 has a first arcuate segment corresponding to the first rotation region a and a second arcuate segment corresponding to the second rotation region b. The pot body assembly also includes a first return member 60 disposed between the mounting base 50 and the operating member 20. When the transmission rod 221 is located within the first arcuate segment, the first return member 60 separates from the transmission rod 221. When the transmission rod 221 is located within the second arcuate segment, the first return member 60 applies a return force to the transmission rod 221, causing the transmission rod 221 to rotate into the first arcuate segment. When the lid opening operation is completed and the user no longer operates the operating member 20, the transmission rod 221 located within the second arcuate segment moves back into the first arcuate segment under the action of the first return member 60. Since the transmission rod 221 no longer abuts the mating inclined surface 402, the hook structure 40 returns to the hooked state. When the user subsequently closes the lid, the hook structure 40 automatically engages with the fixed hook on the lid assembly.

[0070] like Figure 10 and Figure 11As shown, the first return member 60 is a torsion spring. The mounting seat 50 is provided with a mounting recess 52 that sinks toward the inner side of the pot body assembly. The mounting recess 52 includes a central mounting area 521 located in the middle of the mounting seat 50 and a reset mounting area 522 located outside the central mounting area 521 and connected to the second arc segment. The mounting recess 52 has a first side wall 523 away from the second arc segment and a second side wall 524 close to the second arc segment. The torsion spring includes a torsion spring body 61 and a first torsion arm 62 and a second torsion arm 63 provided at both ends of the torsion spring body 61. The torsion spring body 61 is located in the central mounting area 521. When the transmission rod 221 is located in the first arc segment, the first torsion arm 62 abuts against the first side wall 523, and the second torsion arm 63 abuts against the second side wall 524. When the transmission rod 221 is located in the second arc segment, the first torsion arm 62 abuts against the first side wall 523, and the second torsion arm 63 abuts against the transmission rod 221. Specifically, when the transmission rod 221 is located in the first arc segment, the first torsion arm 62 and the second torsion arm 63 respectively press against the first side wall 523 and the second side wall 524, and the torsion spring does not apply a force to the transmission rod 221; when the transmission rod 221 is located in the second arc segment, the first torsion arm 62 presses against the first side wall 523, and the second torsion arm 63 disengages from the second side wall 524 and presses against the transmission rod 221. As the transmission rod 221 gradually moves away from the first arc segment, the transmission rod 221 drives the second torsion arm 63 to gradually approach the first torsion arm 62, and the reset force applied by the torsion spring to the transmission rod 221 becomes greater and greater. When the tripping action is completed and the user releases the operating knob 211, the torsion spring applies a reset force to the transmission rod 221, so that the transmission rod 221 moves out of the second arc segment. At this time, the second torsion arm 63 presses against the second side wall 524 and no longer applies a reset force to the transmission rod 221. The setting of the mounting recess 52 provides an installation space for the torsion spring. When the transmission rod 221 moves into the second arc segment, the second torsion arm 63 applies a reset force to the transmission rod 221, so that the transmission rod 221 can be reset to the first arc segment, avoiding affecting the automatic fastening function of the hook structure 40.

[0071] like Figure 10 and Figure 11 As shown, a stopper is provided at one end of the first side wall 523 close to the operating knob 211 , and the stopper can stop and limit the first torsion arm 62 to prevent the first torsion arm 62 from being separated from the mounting seat 50 .

[0072] Specifically, a mounting protruding ring is provided in the central mounting area 521 , and the torsion spring body 61 is sleeved on the mounting protruding ring.

[0073] like Figure 4 、 Figure 5 and Figure 7As shown, the pot body assembly further includes a locking member 70, which is movably disposed on the housing 10 in the vertical direction and is exposed upward from the housing 10. The locking member 70 has an unlocked position and a locked position. When the locking member 70 is subjected to downward pressure, it can switch from the locked position to the unlocked position. When the locking member 70 is in the unlocked position, the driving member 30 can move. When the locking member 70 is in the locked position, the locking member 70 and the driving member 30 are locked and engaged. Specifically, when the locking member 70 is not subjected to downward pressure (i.e., when the lid assembly is not closed on the pot body assembly), the locking member 70 locks the driving member 30, facilitating alignment between the driving member 30 and the corresponding structure on the lid assembly when the user closes the lid.

[0074] like Figures 5 to 7 As shown, the locking member 70 includes a trigger portion 71, a locking portion 72, and a second return member. The trigger portion 71 extends upward from the housing 10, and the locking portion 72 is located below the trigger portion 71 and is capable of lockingly engaging with the driver 30. The second return member applies an upward force to the trigger portion 71 and / or the locking portion 72 to maintain the locking member 70 in the locked position. When the lid assembly is not closed on the pot assembly, the locking member 70 moves to the locked position under the action of the second return member. The locking portion 72 locks the driver 30 to restrict lateral movement of the driver 30, and the trigger portion 71 extends a greater height from the housing 10. When the lid assembly is closed on the pot assembly, the lid assembly presses the trigger portion 71 downward and overcomes the force of the second return member (in this case, the trigger portion 71 may extend a lesser height from the housing 10 or not extend from the housing 10), causing the locking member 70 to move downward to the unlocked position. The locking portion 72 unlocks the driver 30, allowing the driver 30 to move.

[0075] like Figure 6 and Figure 7 As shown, a locking hole 133 is provided on the middle plate 13 for the trigger portion 71 to pass upward; a first guide column 134 is also provided below the middle plate 13, and a guide hole 723 is provided on the locking portion 72. The first guide column 134 extends downward and passes through the guide hole 723 downward. The second reset member is a compression spring that is sleeved on the first guide column 134 and located below the locking portion 72. The locking member 70 also includes a mounting plate connected to the bottom of the middle plate 13 and extending to the bottom of the first guide column 134. The two ends of the compression spring respectively press against the locking portion 72 and the mounting plate to apply an upward pressing force to the locking portion 72.

[0076] like Figure 5 and Figure 7As shown, the locking member 70 includes a locking hook 721 having a locking slot 722 opening upward. The driving member 30 is provided with a locking rod 32. When the locking member 70 is in the unlocked position, the locking rod 32 is located above the locking slot 722. When the locking member 70 is in the locked position, the locking rod 32 is located within the locking slot 722. The locking hook 721 having the locking slot 722 cooperates with the locking rod 32 to lock the driving member 30, which has the advantages of simple structure and reliable locking.

[0077] like Figure 7 As shown, the locking hook 721 includes a connecting arm, a first hook body and a second hook body connected in sequence, the connecting arm extends downward, the first hook body is connected to the lower end of the connecting arm and extends in the transverse direction, the second hook body is connected to the end of the second hook body away from the connecting arm and extends upward, and a locking groove 722 is formed between the connecting arm, the first hook body and the second hook body. The width of the upper end surface of the second hook body gradually decreases in the direction from bottom to top to guide the movement of the locking rod 32 into and out of the locking groove 722.

[0078] like Figures 12 to 15 As shown, the present application also provides a cooking utensil. An embodiment of the cooking utensil of the present application includes a pot body assembly and a cover body assembly that can be opened and closed to cover the pot body assembly. The pot body assembly is the pot body assembly described above, wherein the cover body assembly includes a mounting cover 80, a locking member 90 that is movably disposed on the mounting cover 80, and a swinging member 100 disposed on the mounting cover 80. The driving member 30 can cooperate with the swinging member 100 to drive and drive the swinging member 100 to swing. When the swinging member 100 swings, it drives the locking member 90 to switch between a locked position and a avoidance position. When the driving member 30 moves horizontally, it drives the swinging member 100 to swing, thereby achieving the switching of the locking member 90 between the locked position and the avoidance position through the swinging member 100, which has the advantage of a simple structure.

[0079] like Figure 4 and Figure 13 As shown, the pot body 120 of the pot body assembly is provided with a plurality of pot teeth, and the locking member 90 is a locking cover rotatably arranged under the mounting cover 80. The locking cover is provided with a plurality of cover teeth corresponding to the plurality of pot teeth one by one. When the locking member 90 is rotated, the cover teeth can correspond to the pot teeth or the cover teeth and the pot teeth can be misaligned.

[0080] like Figures 12 to 14As shown, the swing member 100 includes a swing rod 101, a rotating portion 102 provided at one end of the swing rod 101, and a drive engaging portion 103 provided at the other end of the swing rod 101. The drive member 30 can cooperate with the drive engaging portion 103 to drive the swing member 100 to swing about the rotating portion 102. The drive member 30 cooperates with the drive engaging portion 103 to cause the swing member 100 to swing about the center of the rotating portion 102, thereby achieving rotation of the locking member 90 through the swing member 100.

[0081] like Figure 13 As shown, a rotating support 84 is provided on the mounting cover 80 , and the rotating portion 102 of the swing member 100 is sleeved on the rotating support 84 , so that the swing member 100 can swing around the center of the rotating support 84 .

[0082] Preferably, the longer the swing member 100 is, the better, so that the driving member 30 can drive the swing member 100 to swing a smaller angle and then drive the locking member 90 to rotate a preset angle.

[0083] like Figures 12 to 14 As shown, the cover assembly further includes an upper cover 130 disposed above the mounting cover 80. The swinging member 100 is disposed between the mounting cover 80 and the upper cover 130. The drive engaging portion 103 of the swinging member 100 is a plate-like structure, and a drive hole 104 is provided on the drive engaging portion 103. The mounting cover 80 is provided with an arcuate guide groove 81, and the locking member 90 is provided with a guide post 91. The guide post 91 extends upward and passes through the arcuate guide groove 81 and the drive hole 104 in sequence. When the swinging member 100 swings, the guide post 91 is driven by the drive hole 104 to move along the arcuate guide groove 81, thereby driving the locking member 90 to rotate.

[0084] like Figure 4 、 Figure 12 and Figure 13 As shown, the cooking appliance further includes a transmission assembly 110 rotatably disposed between the driving member 30 and the swinging member 100. When the driving member 30 moves, the transmission assembly 110 rotates. The transmission assembly 110 cooperates with the swinging member 100 to drive the swinging member 100 to swing. The transmission assembly 110 converts the movement of the driving member 30 into the swinging of the swinging member 100, thereby transmitting the driving force on the pot body assembly to the lid assembly.

[0085] In this embodiment, since the driving assembly is arranged on the pot body assembly, the driving assembly can successively drive the pot teeth to rotate and drive the hook structure 40 to swing. In this way, there is no need to set an operating handle or other structures on the cover assembly, and the space above the cover assembly can be vacated to set a larger control panel or other structures, thereby improving the user experience.

[0086] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 13 and Figure 14 As shown, the transmission assembly 110 includes a lower transmission assembly mounted on the pot body assembly and an upper transmission assembly mounted on the lid assembly. The lower transmission assembly includes a lower gear 111 and a lower coupling 112. Lower gear 111 is provided with lower driven teeth, and the driver 30 is provided with lower driving teeth 34. When the driver 30 moves laterally, the lower driving teeth 34 engage with the lower driven teeth, driving the lower gear 111 to rotate about a vertical axis. A fixed connection is provided between lower gear 111 and lower coupling 112, allowing the lower coupling 112 to rotate synchronously with the lower gear 111. The upper transmission assembly includes an upper coupling 113 and an upper gear 114. The upper coupling 113 and lower coupling 112 are plugged into and fixedly engaged with each other. When the lid assembly is placed over the pot body assembly, rotation of the lower coupling 112 drives the upper coupling 113 synchronously. The fixed connection between the upper coupling 113 and upper gear 114 allows the upper gear 114 to rotate synchronously with the upper coupling 113. The upper gear 114 is provided with an upper driving tooth, and the driving mating portion 103 of the swing member 100 is provided with an upper driven tooth 106. The upper driven tooth 106 is meshed with the upper driving tooth, so that when the upper gear 114 rotates, the swing member 100 is driven to swing.

[0087] like Figure 6 As shown, the middle plate 13 includes a lower transmission seat 131, and a first transmission hole 132 is provided on the lower transmission seat 131. The lower coupling 112 and the lower gear 111 are respectively installed in the first transmission hole 132 from the upper and lower sides of the first transmission hole 132 and fixedly connected. The lower driven tooth of the lower gear 111 is located below the first transmission hole 132 to mesh with the lower driving tooth 34. Figure 13 As shown, the mounting cover 80 is further provided with an upper transmission seat 82, which is provided with a second transmission hole 83. An upper gear 114 and an upper coupling 113 are respectively installed in the second transmission hole 83 from the upper and lower sides thereof. The upper drive teeth of the upper gear 114 are located above the upper transmission seat 82. When the cover assembly is placed on the pot body assembly, the lower transmission seat 131 extends below the upper transmission seat 82, and the upper coupling 113 and the lower coupling 112 are locked to rotate synchronously.

[0088] like Figure 13 and Figure 15 As shown, the cover assembly further includes an upper locking member 140. When the cover assembly is not closed on the pot body assembly, the upper locking member 140 can lock the swing member 100, so that the swing member 100 stays in a position where the locking member 90 is kept in the misaligned position between the cover teeth and the pot teeth (that is, the locking member 90 is kept in the avoidance position), thereby facilitating the misalignment between the pot teeth and the cover teeth when the cover is subsequently closed. Specifically, Figure 15As shown, the upper locking member 140 includes a main body, a cantilever arranged on the main body, and a locking protrusion 141 arranged below the free end of the cantilever. A mounting cylinder 142 is provided on the main body, and a third reset member 150 is provided in the mounting cylinder 142. The third reset member 150 is a compression spring, and the two ends of the third reset member 150 respectively press against the lower wall surface of the mounting cylinder 142 and the upper cover 130; a limiting hole 105 is provided on the swing member 100; and a perforated structure is provided on the mounting cover 80 for the lower end of the main body to pass downward. When the cover assembly is not covered on the pot body assembly, the upper locking member 140 moves downward as a whole under the action of the third restoring member 150, so that the locking protrusion 141 is inserted into the limiting hole 105, thereby restricting the swinging member 100 from swinging; when the cover assembly is covered on the pot body assembly, the pot body assembly will push up against the upper locking member 140, so that the upper locking member 140 moves upward as a whole and the locking protrusion 141 leaves the limiting hole 105. At this time, the swinging member 100 can swing.

[0089] The following describes the movement and transmission relationship of various components during the opening and closing of the lid in conjunction with the specific structure of the cooking appliance:

[0090] In the open state:

[0091] The hook structure 40 is kept in the hook state under the action of the elastic member; the locking member 70 is kept in the locked position under the action of the second reset member, and the locking rod 32 on the driving member 30 is located in the locking groove 722 of the lock hook 721, limiting the movement of the driving member 30 in the lateral direction; the transmission rod 221 is kept at the intersection of the first arc segment and the second arc segment under the action of the second torsion arm 63 of the first reset member 60; the upper locking member 140 moves downward under the action of the third reset member 150 and causes the swinging member 100 to stay in the position where the locking member 90 remains in the misaligned position between the cover teeth and the pot teeth (that is, the locking member 90 remains in the locked position).

[0092] During the lid closing process:

[0093] The user first presses down the cover assembly so that the cover assembly is close to the pot body assembly. Since the locking member 90 is kept in the position where the cover teeth and the pot teeth are misaligned under the action of the upper locking member 140, the cover assembly can be pressed down smoothly. During the process of pressing down the cover assembly, the pot body assembly presses upward against the upper locking member 140 so that the upper locking member 140 switches from the position of locking the swinging member 100 to the position of unlocking the swinging member 100, and the cover assembly presses downward against the locking member 70 so that the locking member 70 switches from the locked position to the unlocked position, and the hook structure 40 and the fixed hook on the cover assembly are automatically engaged under the action of the guide slope and the elastic member. At this time, the transmission rod 221 of the operating member 20 is located at the intersection of the second rotation area b and the first rotation area a (that is, the transmission rod 221 is located at the intersection of the first arc segment and the second arc segment and at the intersection of the linkage slot segment 311 and the avoidance slot segment 312).

[0094] Then the user can use the operating part 20 to drive the cover teeth and pot teeth to align. Figure 9 The operating knob 211 is rotated clockwise in the middle, and the transmission rod 221 moves clockwise along the first arc segment. At this time, the transmission rod 221 and the Figure 9 The right side wall of the middle linkage groove section 311 cooperates with the driving member 30 to move Figure 9 The lower driving tooth 34 on the driving member 30 meshes with the lower driven tooth on the lower gear 111, driving the lower gear 111, the lower coupling 112, the upper coupling 113 and the upper gear 114 to move synchronously along Figure 4 and Figure 5 The upper driving teeth of the upper gear 114 mesh with the upper driven teeth 106 on the swing member 100, driving the swing member 100 to swing along the center of the rotating part 102. Figure 13 During the swinging process of the swinging member 100, the locking member 90 is driven to rotate by the cooperation between the guide column 91 and the driving hole 104, so that the locking member 90 is rotated from the position where the cover teeth and the pot teeth are staggered to the position where the cover teeth and the pot teeth are opposite (that is, the locking member 90 is rotated to the locked position) to meet the pressure bearing requirements during the cooking process.

[0095] Through the above steps, when closing the lid, the hook structure between the lid assembly and the pot body assembly is firstly engaged, and then the pot teeth and the lid teeth are aligned.

[0096] In the closed state:

[0097] The hook structure 40 is kept in the hook state under the action of the elastic member; the locking member 70 is kept in the unlocked position due to the downward pressure of the cover assembly, and the upper locking member 140 is kept in the position of the unlocked swing member 100 due to the upward pressure of the pot assembly; the transmission rod 221 is located at Figure 10 The rightmost end of the middle arc-shaped slot 51 , that is, the operating knob 211 is located at the right-hand limit position; the cover teeth and the pot teeth are kept in facing positions.

[0098] During the opening process:

[0099] The user first drives the cover teeth and pot teeth to dislocate by operating the part 20, and then Figure 9 The operating knob 211 is rotated counterclockwise in the middle, and the transmission rod 221 moves counterclockwise along the first arc segment. At this time, the transmission rod 221 and Figure 9 The left side wall of the middle linkage slot section 311 cooperates with the driving member 30 to move Figure 9 The left side of the drive member 30 moves, and the lower driving tooth 34 on the lower driven tooth on the lower gear 111 is engaged, driving the lower gear 111, the lower coupling 112, the upper coupling 113 and the upper gear 114 to move synchronously along the Figure 4 and Figure 5 The upper driving teeth of the upper gear 114 mesh with the upper driven teeth 106 on the swing member 100, driving the swing member 100 to swing along the center of the rotating part 102. Figure 13 The swing member 100 swings in the counterclockwise direction, and the locking member 90 is driven to rotate by the cooperation between the guide column 91 and the drive hole 104 during the swing process, until the transmission rod 221 moves to Figure 10 The leftmost end of the first arc segment (i.e., the intersection of the first arc segment and the second arc segment) causes the locking member 90 to rotate from a position where the cover teeth and the pot teeth are opposite to each other to a position where the cover teeth and the pot teeth are staggered.

[0100] The user continues along Figure 9 The operating knob 211 is rotated counterclockwise, and the transmission rod 221 enters the second arc segment and the avoidance groove segment 312. Since the avoidance groove segment 312 avoids the trajectory of the transmission rod 221, the transmission rod 221 no longer drives the driving member 30 to move during the rotation process. At this time, the locking rod 32 on the driving member 30 moves just above the lock groove 722, and the free end of the transmission rod 221 hits the matching inclined surface 402, and the transmission rod 221 continues to move along the Figure 9 The counterclockwise rotation of the hook structure 40 drives the hook structure 40 to swing along the axis 4 as the center. Figure 5 Swing clockwise until the transmission rod 221 moves to Figure 10 The lowermost end of the second arc segment causes the hook structure 40 to disengage from the fixed hook on the cover assembly. At this time, the cover assembly is automatically flipped open under the action of the cover opening torsion spring set between the pot body assembly and the cover assembly.

[0101] Through the above steps, when opening the lid, the pot teeth and the lid teeth between the lid assembly and the pot body assembly are firstly removed, and then the hook structure is released.

[0102] 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.

[0103] 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.
