Description

Technical Field

[0001] This invention relates to the field of small household appliance technology, and more specifically, to a cooking appliance. Background Technology

[0002] In related technologies, a stirring component with a rotating shaft extending laterally is installed in a cooking appliance with a stir-frying function, which can fully stir the food in the cooking cavity and improve the cooking effect.

[0003] To accommodate user habits, the pot body is typically designed to be removable within the base along the vertical direction. The direction in which the user removes or lowers the pot body is perpendicular to the direction of rotation of the stirring assembly's shaft. When the user attempts to lower or remove the pot body, the stirring assembly's shaft may interfere with the base, or the drive shaft of the drive mechanism may interfere with the pot body, preventing the user from smoothly lowering or removing the pot body. Summary of the Invention

[0004] The main objective of this invention is to provide a cooking appliance that solves the problem in related technologies where the rotating shaft of the stirring assembly interferes with the base or the drive shaft of the drive structure interferes with the pot body, making it impossible for the user to smoothly put down or take out the pot body.

[0005] To achieve the above objectives, the present invention provides a cooking appliance, comprising: a base having a receiving cavity with a top opening; a pot assembly including a pot body removably disposed within the base and a stirring blade rotatably disposed within the pot body, the rotation axis of the stirring blade extending in a transverse direction; a drive mechanism disposed within the base, the output shaft of the drive mechanism extending in a transverse direction and capable of driving the stirring blade to rotate; a transmission cylinder retractably disposed on the output shaft of the drive mechanism and capable of rotating synchronously with the output shaft, the transmission cylinder having a drive position for engaging with the rotating shaft and driving the rotating shaft to rotate, and a clearance position for separating from the rotating shaft; and a first reset member disposed between the output shaft and the transmission cylinder; wherein, during the process of placing the pot assembly into the base, the rotating shaft pushes the transmission cylinder to move in a transverse direction, gradually moving away from the drive position and reaching the clearance position, and the transmission cylinder, under the action of the first reset member, returns from the clearance position to the drive position, thereby realizing the engagement between the rotating shaft and the transmission cylinder.

[0006] Applying the technical solution of this invention, the stirring blade is rotatably mounted inside the pot. The base is equipped with a drive mechanism and a transmission cylinder. When the transmission cylinder is in the drive position, the drive mechanism can drive the stirring blade to rotate to stir the food, realizing an automatic cooking function. When cooking is complete and the pot needs to be removed, the user only needs to drive the transmission cylinder from the drive position to the clearance position to remove the pot assembly from the base, facilitating user operation. After the pot assembly is removed from the base, the transmission cylinder moves from the clearance position to the drive position under the action of the first reset member. When the pot needs to be placed, the user only needs to lower the pot assembly. During the lowering process, the rotating shaft pushes the transmission cylinder to move laterally away from the drive position and reach the clearance position. After the pot assembly is placed in place, the transmission cylinder moves from the clearance position to the drive position under the action of the first reset member, and the rotating shaft and the transmission cylinder are engaged. That is, when the pot needs to be removed, the user only needs to operate the transmission cylinder. The above structure avoids interference between components when placing or removing the pot and has the advantage of simple operation. Therefore, the technical solution of this application can effectively solve the problem in the related technology that the rotating shaft of the stirring component interferes with the base or the driving shaft of the driving structure interferes with the pot body, making it impossible for the user to put down or take out the pot body smoothly.

[0007] Furthermore, the transmission cylinder also has a limiting position. When the transmission cylinder is in the limiting position, the distance between it and the rotating shaft is greater than the distance between the transmission cylinder and the rotating shaft when it is in the avoidance position. The cooking appliance also includes a limiting mechanism, which is located inside the base. The limiting mechanism includes a stop mechanism, a locking mechanism, and a reversing mechanism. The stop mechanism is located at the first end of the reversing mechanism, and the locking mechanism is located at the second end of the reversing mechanism. When the pot assembly is placed inside the base, the pot assembly and the stop mechanism abut against each other, and the locking mechanism locks the transmission cylinder in the limiting position. When the pot assembly leaves the base, the locking mechanism unlocks the transmission cylinder, allowing it to move from the limiting position to the driving position under the action of the first reset member. When cooking is complete and the pot needs to be removed, the driving transmission cylinder moves from the driving position to the limiting position. At this time, the limiting mechanism locks the transmission cylinder in the limiting position, meaning that the user does not need to continuously operate the transmission cylinder; the user can use both hands to remove the pot assembly from the base, facilitating user operation.

[0008] Furthermore, the locking mechanism includes a locking frame, which is movably disposed within the base and has a locked position for locking the transmission cylinder and an unlocked position separate from the transmission cylinder. The reversing mechanism includes a transmission rod, which drives the locking frame to move from the locked position to the unlocked position when the pot assembly leaves the base. When the locking frame is in the locked position, it locks the transmission cylinder, holding it in a limited position; when the locking frame is in the unlocked position, it unlocks the transmission cylinder, disengaging it from the limited position.

[0009] Furthermore, the limiting mechanism also includes a second reset member disposed between the base and the locking frame. The second reset member applies an upward reset force to the locking frame to keep the locking frame in the locked position. The second reset member ensures that the locking frame remains in the locked position, so that when the transmission cylinder moves to the limiting position, the transmission cylinder can be locked and kept in the limiting position, facilitating the user's subsequent pot removal operation.

[0010] Furthermore, the limiting mechanism also includes a third reset member disposed between the base and the lower part of the transmission rod. The third reset member abuts upward against the first end of the transmission rod, causing the second end of the transmission rod to move the locking frame from the locked position to the unlocked position and remain in the unlocked position. The reset force of the third reset member is greater than the reset force of the second reset member. The third reset member, in conjunction with the pot assembly, allows the locking frame to switch between the locked and unlocked positions, enabling the transmission cylinder to be locked by the locking frame when the pot needs to be removed, thus facilitating the user's pot removal operation. Since the reset force of the third reset member is greater than that of the second reset member, when the pot assembly leaves the base, the transmission rod, driven by the third reset member, can overcome the reset force of the second reset member, causing the locking frame to move from the locked position to the unlocked position and remain in the unlocked position.

[0011] Furthermore, a fixing frame is provided inside the base, adjacent to the drive mechanism. The fixing frame includes a horizontal plate and a vertical plate connected to each other. A locking frame is located below the output shaft. The locking frame includes a first connecting rod and a first latch. The first end of the first connecting rod away from the pot assembly is rotatably connected to the vertical plate. The first latch is located on the second end of the first connecting rod near the pot assembly and can lock into the transmission cylinder. The two ends of the second reset member abut against the first connecting rod and the horizontal plate respectively. That is, the locking frame is rotatably connected to the base, eliminating the need for an additional limiting structure to restrict the movement direction of the locking frame, thus simplifying the structure.

[0012] Furthermore, the locking frame also includes a second connecting rod connected to the second end of the first connecting rod and extending downward. The transmission rod is a lever structure, with the first end of the lever structure engaging with the pot assembly, and the second end of the lever structure being movably connected to the second connecting rod to move the locking frame from the locked position to the unlocked position. By setting a lever structure between the pot assembly and the locking frame, the locking frame can remain in the locked position when the pot assembly is placed inside the base, offering the advantage of a simple structure.

[0013] Furthermore, a notch is provided at the second end of the transmission rod, and the second connecting rod passes through the notch. A stop block is provided at the lower end of the second connecting rod, which engages with a stop on the lower surface of the transmission rod. This stop block engages with the lower surface of the transmission rod, preventing the second connecting rod from disengaging from the transmission rod and ensuring that the second connecting rod is always in a position where it can be driven by the transmission rod. Providing a notch at the second end of the transmission rod, with the second connecting rod passing through the notch, facilitates the assembly of the transmission rod and the locking frame.

[0014] Furthermore, the cooking appliance also includes a switching mechanism, which is located within the base and drives the transmission cylinder from the driving position to the limiting position, so that the transmission cylinder is locked by the limiting mechanism. When the user needs to remove the pot, they first operate the switching mechanism to drive the transmission cylinder from the driving position to the limiting position. After the transmission cylinder moves to the limiting position, it will be locked in the limiting position by the limiting mechanism. At this time, the user can use both hands to remove the pot assembly from the base, facilitating user operation.

[0015] Furthermore, the switching structure includes a switching sleeve movably disposed in the lateral direction. A raised edge is provided on the outer wall of the transmission cylinder, and a stepped portion is provided on the inner wall of the switching sleeve to engage with a stop on the raised edge. A second latch is provided on the outer wall of the switching sleeve to engage with a limiting mechanism. With the stepped portion and the raised edge engaging, when the switching sleeve moves in the lateral direction, it drives the transmission cylinder from the driving position to the limiting position. Conversely, when the transmission cylinder moves from the limiting position to the driving position, it also drives the transmission cylinder to move, achieving synchronous movement. By providing the first and second latches, the locking frame locks the switching sleeve, thereby locking the transmission cylinder and keeping it in the limiting position, facilitating the user's subsequent removal of the pot assembly.

[0016] Furthermore, the switching structure also includes a pressing mechanism exposed on the base, which drives the switching sleeve to move. When the pot needs to be removed, the user only needs to press the pressing mechanism to move the transmission cylinder from the driving position to the limit position, and the transmission cylinder will be held in the limit position by the limit mechanism, which has the advantage of simple operation.

[0017] Furthermore, the switching structure also includes a connecting rod connected to the outer wall of the switching sleeve and a first swing rod disposed between the pressing structure and the connecting rod. The first swing rod converts the vertical force of the pressing structure into a lateral force acting on the connecting rod, which in turn drives the switching sleeve to move laterally, thereby driving the transmission cylinder to move.

[0018] Furthermore, the first end of the first swing rod is located below the pressing structure and abuts against it. The switching structure also includes a linkage pin at the second end of the first swing rod and a linkage groove at the end of the connecting rod away from the switching sleeve. The linkage pin is rotatably disposed in the linkage groove and can slide along it. The first swing rod can convert the vertical movement of the pressing structure into the horizontal movement of the connecting rod. By using the cooperating linkage pin and linkage groove to convert the swing of the first swing rod into the horizontal movement of the connecting rod and the switching sleeve, jamming can be avoided.

[0019] Furthermore, a guide ramp is provided on the side of the connecting rod facing the pot assembly. When the pot assembly is placed into the base, the rotating shaft abuts against the guide ramp, causing the switching sleeve to move the transmission cylinder from the driving position to the avoidance position. When lowering the pot assembly, the rotating shaft abuts against the guide ramp and pushes the connecting rod, switching sleeve, and transmission cylinder to move away from the rotating shaft, thereby avoiding the rotating shaft and allowing the pot assembly to be lowered smoothly.

[0020] Furthermore, the transmission cylinder includes a first transmission cylinder section, a second transmission cylinder section, and a connecting cylinder section disposed between the first and second transmission cylinder sections. When the transmission cylinder is in the driving position, the first transmission cylinder section is inserted into the rotating shaft. The end of the first transmission cylinder section away from the second transmission cylinder section has an end wall, and a first reset member is disposed between the end wall and the output shaft; and / or, the driving mechanism is a drive motor. When the rotating shaft, the switching sleeve, and the locking frame do not apply any force to the transmission cylinder to move it to or maintain it in the limit position, the transmission cylinder will be maintained in the driving position or moved from the limit position to the driving position and maintained in the driving position under the action of the first reset member.

[0021] Furthermore, the reversing mechanism includes a transmission rod, and the locking mechanism includes a third latch disposed at the second end of the reversing mechanism. The aforementioned third latch has a simple structure and can lock the transmission cylinder in a limited position, facilitating the user's pot removal operation.

[0022] Furthermore, the reversing mechanism includes a transmission rod, and a fixed frame is provided inside the base. The fixed frame is adjacent to the drive mechanism and includes a horizontal plate and a vertical plate connected to each other. A locking mechanism is located below the output shaft and includes a second swing rod and a fourth latch. The first end of the second swing rod is rotatably connected to the vertical plate, and the fourth latch is located at the second end of the second swing rod. When the pot assembly is placed inside the base, the pot assembly abuts against the supporting mechanism, and the transmission rod pushes upward against the second swing rod, so that the fourth latch can lock the transmission cylinder in a limited position. When the pot assembly leaves the base, the second swing rod falls, so that the fourth latch can unlock the transmission cylinder. The structure of the second swing rod and the fourth latch is simple, and the fourth latch can lock the transmission cylinder in a limited position, facilitating the user's pot removal operation.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

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

[0041] like Figure 1 and Figure 5 as well as Figure 8 As shown, the cooking appliance of this embodiment includes: a base 10, a pot body assembly 20, a drive mechanism 30, and a linkage structure 40. The base 10 has a receiving cavity with a top opening; the pot body assembly 20 includes a pot body 21 removably disposed within the base 10 and a stirring blade 22 rotatably disposed within the pot body 21, with the rotation axis 221 of the stirring blade 22 extending laterally; the drive mechanism 30 is disposed within the base 10, and the output shaft 31 of the drive mechanism 30 extends laterally and is capable of driving the stirring blade 22 to rotate; the linkage structure 40 includes a transmission cylinder 41 movably disposed on the output shaft 31 of the drive mechanism 30 and capable of rotating synchronously with the output shaft 31, and a linkage structure 40 disposed on the transmission cylinder 41. The first reset member 42 between the output shaft 31 and the transmission cylinder 41 has a driving position that is inserted into and drives the rotating shaft 221 to rotate, and a clearance position that is separated from the rotating shaft 221. When the pot assembly 20 is placed into the base 10, the rotating shaft 221 pushes the transmission cylinder 41 to move away from the driving position and reach the clearance position in the lateral direction. Under the action of the first reset member 42, the transmission cylinder 41 returns from the clearance position to the driving position, so as to realize the insertion and engagement between the rotating shaft 221 and the transmission cylinder 41.

[0042] Using the technical solution of this embodiment, the stirring blade 22 is rotatably disposed inside the pot body 21. The base 10 is provided with a drive mechanism 30 and a linkage structure 40. When the transmission cylinder 41 of the linkage structure 40 is in the drive position, the drive mechanism 30 can drive the stirring blade 22 to rotate to stir the food, thereby realizing the automatic cooking function. When the cooking is finished and the pot needs to be removed, the user only needs to drive the transmission cylinder 41 from the drive position to the avoidance position to remove the pot body assembly 20 from the base 10, which is convenient for the user. After the pot body assembly 20 is removed from the base 10, the transmission cylinder 41 moves from the avoidance position to the drive position under the action of the first reset member 42. When the pot needs to be placed down, the user only needs to lower the pot body assembly 20. During the downward movement of the pot body assembly 20, the rotating shaft 221 will push the transmission cylinder 41 to move laterally away from the drive position and reach the avoidance position. After the pot body assembly 20 is placed in place, the transmission cylinder 41 moves from the avoidance position to the drive position under the action of the first reset member 42, and the rotating shaft 221 and the transmission cylinder 41 are engaged. When the pot needs to be removed, the user only needs to operate the transmission cylinder 41. The above structure avoids interference between components when placing or removing the pot and has the advantage of simple operation. Therefore, the technical solution of this embodiment can effectively solve the problem in related technologies where the rotating shaft of the stirring assembly interferes with the base or the drive shaft of the drive structure interferes with the pot body, making it impossible for the user to smoothly place or remove the pot.

[0043] The "lateral direction" mentioned above can be a horizontal direction or a direction that forms a certain angle with the horizontal direction (such as within 30°). Specifically, the drive mechanism 30 mentioned above is a drive motor.

[0044] In this embodiment, when the user directly or indirectly operates (e.g., inserts the pot assembly) the transmission cylinder 41, the transmission cylinder 41 retracts relative to the output shaft 31, thereby reaching a clearance position (not shown). This clearance position is instantaneous; when the transmission cylinder 41 is not subjected to external force, it will not remain in this position. The transmission cylinder 41 also has a limiting position. When the transmission cylinder 41 is in the limiting position, the distance between it and the rotating shaft 221 is greater than the distance between it and the rotating shaft 221 when it is in the clearance position. That is, during the process of the transmission cylinder 41 moving away from the rotating shaft 221, it will first reach the clearance position, and then move a certain distance before reaching the limiting position. Specifically, when the pot assembly 20 is placed into the base 10, the rotating shaft 221 pushes the transmission cylinder 41 to move to the clearance position. At this time, the transmission cylinder 41 is separated from the rotating shaft 221 but has not yet reached the limiting position.

[0045] The cooking appliance in this embodiment also includes a limiting mechanism 60, which is disposed within the base 10. The limiting mechanism includes a pushing mechanism, a locking mechanism, and a reversing mechanism. The pushing mechanism is disposed at the first end of the reversing mechanism, and the locking mechanism is disposed at the second end of the reversing mechanism. When the pot assembly 20 is placed within the base 10, the pot assembly 20 abuts against the pushing mechanism. At this time, after the user operates the transmission cylinder 41 to move it to the limiting position, the locking mechanism locks the transmission cylinder 41 in the limiting position. When the pot assembly 20 leaves the base 10, the locking mechanism unlocks the transmission cylinder 41, causing the transmission cylinder 41 to move from the limiting position to the driving position under the action of the first reset member 42. When the pot assembly 20 is placed back into the base 10 after leaving it, the rotating shaft 221 pushes the transmission cylinder 41 to move laterally from the driving position to the avoidance position. After the pot assembly is placed in place, the transmission cylinder 41 will reset to the driving position to achieve the insertion and engagement between the rotating shaft 221 and the transmission cylinder 41.

[0046] When cooking is complete and the pot needs to be removed, the user can apply a lateral force to the transmission cylinder 41, or the user can convert forces from other directions into a lateral force and apply it to the transmission cylinder 41 through an intermediate transmission mechanism (such as a switching structure, which will be described in detail below). This will drive the transmission cylinder 41 from the driving position to the limit position. At this time, the locking mechanism will lock the transmission cylinder 41 in the limit position, meaning that the user does not need to continuously operate the transmission cylinder 41. The user can use both hands to remove the pot body assembly 20 from the base 10, which is convenient for the user. After being removed from the base 10, the locking mechanism no longer locks the transmission cylinder 41. Under the action of the first reset member 42, the transmission cylinder 41 moves from the limit position to the drive position. When the pot needs to be placed back in, the user only needs to lower the pot body assembly 20. During the downward movement of the pot body assembly 20, the rotating shaft 221 will push the transmission cylinder 41 to move laterally to the clearance position. After the pot body assembly 20 is in place, the transmission cylinder 41 moves from the clearance position to the drive position under the action of the first reset member 42, and the rotating shaft 221 and the transmission cylinder 41 are engaged. That is, when the pot needs to be removed, the user only needs to operate the transmission cylinder 41 once; when the pot needs to be placed back in, the user simply lowers the pot body assembly 20 without any other operation.

[0047] like Figure 4 As shown, in this embodiment, the rotating shaft 221 includes a shaft body 2211 and a sleeve structure 2212 fixedly connected to the shaft body 2211 and sleeved around the outer periphery of the shaft body 2211. When the transmission cylinder 41 is in the driving position, the transmission cylinder 41 and the sleeve structure 2212 are inserted into each other and can drive the rotating shaft 221 to rotate synchronously. Of course, in other embodiments, the shaft body can also be directly inserted into the transmission cylinder.

[0048] like Figure 1As shown, the cooking appliance in this embodiment also includes a cover 70 that is placed on top of the pot body assembly 20. When cooking automatically, the cover 70 can prevent food from splashing out of the pot body assembly 20.

[0049] like Figure 1 , Figure 4 as well as Figure 7 As shown, in order to facilitate the user to drive the transmission cylinder 41, the cooking appliance also includes a switching structure 50, which is set in the base 10 and drives the transmission cylinder 41 from the driving position to the limit position.

[0050] In this embodiment, as Figure 2 , Figure 4 as well as Figures 6 to 8 As shown, the switching structure 50 includes a switching sleeve 51 movably disposed in the lateral direction. A raised edge 411 is provided on the outer wall of the transmission cylinder 41, and a stepped portion 511 is provided on the inner wall of the switching sleeve 51, which engages with the raised edge 411. The stepped portion 511 and the raised edge 411 engage, so that when the switching sleeve 51 moves in the lateral direction, it drives the transmission cylinder 41 from the driving position to the limiting position, and when the transmission cylinder 41 moves from the limiting position to the driving position, it also drives the switching sleeve 51 to move, achieving synchronous movement of the two. A stepped hole is provided inside the switching sleeve 51, and the stepped surface of the stepped hole forms the aforementioned stepped portion 511. Of course, the stepped portion can also be formed in other ways; for example, a raised ring can be provided on the inner wall of the switching sleeve, forming the stepped portion.

[0051] like Figures 1 to 4 As shown, the switching structure 50 also includes a pressing structure 52 exposed on the base 10, which drives the switching sleeve 51 to move. When the pot needs to be removed, the user only needs to press the pressing structure 52 to move the transmission cylinder 41 from the driving position to the limit position, and the transmission cylinder 41 will be held in the limit position by the limit mechanism 60. The above structure has the advantage of simple operation.

[0052] like Figures 1 to 4 , Figure 7 as well as Figure 11As shown, the switching structure 50 also includes a connecting rod 53 connected to the outer wall of the switching sleeve 51 and a first swing rod 54 disposed between the pressing structure 52 and the connecting rod 53. Specifically, to facilitate user operation, in this embodiment, the pressing structure 52 extends vertically, with its upper end exposed above the base 10. During use, the user operates the pressing structure 52 by pressing down. The first swing rod 54 converts the vertical force of the pressing structure 52 into a lateral force acting on the connecting rod 53. The connecting rod 53 drives the switching sleeve 51 to move laterally, thereby driving the transmission cylinder 41 to move. Of course, in other embodiments, the pressing structure can also extend laterally, in which case the user needs to operate the pressing structure laterally.

[0053] Specifically, such as Figure 3 As shown, the pressing structure 52 includes a mounting bracket 522 fixedly connected to the base 10, a pressing cap 521 disposed above the mounting bracket 522, a pressing rod 523 fixedly connected to the pressing cap 521 and movably disposed through the mounting bracket 522, and a fourth reset member 524 disposed between the mounting bracket 522 and the pressing cap 521. The mounting bracket 522 is provided with a receiving space with a top opening, and the pressing cap 521 is movably disposed in the receiving space. The base 10 is provided with a through-hole structure, and the pressing cap 521 passes through the through-hole structure. The lower end of the pressing cap 521 is provided with an anti-disengagement edge that can cooperate with the stop of the through-hole structure to prevent the pressing cap 521 from disengaging from the base 10. The through-hole structure and the mounting bracket 522 limit the range of movement of the pressing cap 521 in the vertical direction. The fourth reset member 524 is sleeved on the outer periphery of the pressing rod 523 and abuts against the pressing cap 521 and the mounting bracket 522 respectively. When the user no longer applies force to the pressing cap 521, the pressing cap 521 will rebound under the action of the fourth reset member 524. The mounting bracket 522 is provided with a retaining ring structure, and the fourth reset member 524 is partially located within the retaining ring structure. The retaining ring structure can limit and guide the fourth reset member 524 so that it can be kept within the retaining ring structure, ensuring the stability of the force exerted by the fourth reset member 524 on the pressing cap 521. Specifically, in this embodiment, the fourth reset member 524 is a spring.

[0054] Specifically, in this embodiment, such as Figure 2 , Figure 3 and Figure 7 As shown, both the pressing rod 523 and the connecting rod 53 have a cross-section in the shape of a cross, which ensures the strength of the rod structure. The base 10 is provided with a guide structure that guides the pressing rod 523 and the connecting rod 53, so that the pressing rod 523 can move vertically and the connecting rod 53 can move horizontally.

[0055] like Figure 1 , Figures 4 to 6 as well as Figure 9 As shown, the limiting mechanism 60 includes a locking frame 61 and a transmission rod 62 located between the locking frame 61 and the pot assembly 20. The locking frame 61 is movably disposed within the base 10 and has a locked position for locking the switching sleeve 51 and an unlocked position separated from the switching sleeve 51. The pot assembly 20 drives the locking frame 61 to move from the locked position to the unlocked position via the transmission rod 62. When the locking frame 61 is in the locked position, it locks the switching sleeve 51, thereby locking the transmission cylinder 41 and keeping it in the limiting position. When the locking frame 61 is in the unlocked position, it unlocks the switching sleeve 51, allowing the transmission cylinder 41 to leave the limiting position and move from the limiting position to the driving position under the action of the first reset member 42.

[0056] like Figure 1 , Figures 4 to 6 as well as Figure 9 As shown, the limiting mechanism 60 also includes a second reset member 63 disposed between the base 10 and the locking frame 61. The second reset member 63 applies a reset force to the locking frame 61 to keep the locking frame 61 in the locked position. The second reset member 63 enables the locking frame 61 to remain in the locked position, so that when the transmission cylinder 41 moves to the limiting position, the locking frame 61 can lock the transmission cylinder 41 and keep it in the limiting position, facilitating the user's subsequent pot removal operation. Specifically, in this embodiment, the second reset member 63 is a compression spring that applies an upward force to the locking frame 61.

[0057] like Figure 1 , Figures 4 to 7 as well as Figure 12 As shown, a fixing frame 11 is provided inside the base 10. The fixing frame 11 is arranged adjacent to the drive mechanism 30. The fixing frame 11 includes a horizontal plate and a vertical plate connected to each other. The locking frame 61 is located below the output shaft 31. The locking frame 61 includes a first connecting rod 611 and a first latch 612. The first end of the first connecting rod 611 away from the pot assembly 20 is rotatably connected to the vertical plate. The first latch 612 is provided on the second end of the first connecting rod 611 near the pot assembly 20. A second latch 512 is provided on the outer wall of the switching sleeve 51, which can lock and cooperate with the first latch 612. The two ends of the second reset member 63 abut against the first connecting rod 611 and the horizontal plate respectively. Preferably, a positioning post is provided on the lower surface of the first connecting rod 611, and the top end of the second reset member 63 is sleeved on the positioning post.

[0058] By setting the first latch 612 and the second latch 512, the locking frame 61 locks the switching sleeve 51, thereby locking the transmission cylinder 41 and keeping it in the limited position, which facilitates the user's subsequent removal of the pot assembly 20. Specifically, the opposing surfaces of the first latch 612 and the second latch 512 are provided with guide slopes. When the user needs to remove the pot, the locking frame 61 is kept in the locked position under the action of the second reset member 63. During the process of the transmission cylinder 41 moving from the driving position to the limited position under the drive of the switching structure 50, the sloped structures on the first latch 612 and the second latch 512 abut against each other. The second latch 512 applies a downward force to the first latch 612 to overcome the elastic force of the second reset member 63, so that the first latch 612 avoids the second latch 512. When the transmission cylinder 41 moves to the limited position, the second latch 512 passes over the first latch 612 and engages with the first latch 612.

[0059] In this embodiment, the locking frame 61 is rotatably connected to the base 10, eliminating the need for additional limiting structures to restrict the movement direction of the locking frame 61, thus simplifying the internal structure of the base 10.

[0060] like Figures 5 to 6 As shown, the locking frame 61 also includes a second connecting rod 613 connected to the second end of the first connecting rod 611 and extending downward. The transmission rod 62 is a lever structure. The first end of the lever structure can abut against the pot assembly 20, and the second end of the lever structure is movably connected to the second connecting rod 613 to drive the locking frame 61 from the locked position to the unlocked position. Specifically, by setting a lever structure between the pot assembly 20 and the locking frame 61, the locking frame 61 can be kept in the locked position when the pot assembly 20 is placed inside the base 10. The above structure has the advantage of simple structure.

[0061] like Figures 4 to 6 as well as Figure 10 As shown, the second end of the transmission rod 62 has a notch 621, and the second connecting rod 613 passes through the notch 621. The lower end of the second connecting rod 613 has a stop block 6131 that can cooperate with the lower surface of the transmission rod 62. The stop block 6131 can cooperate with the lower surface of the transmission rod 62 to prevent the second connecting rod 613 from disengaging from the transmission rod 62, so that the second connecting rod 613 is always in a position that can be driven by the transmission rod 62. The locking frame 61 includes a first connecting rod 611 and a second connecting rod 613 that are connected to each other and arranged at an angle. The lower end of the second connecting rod 613 has a stop block 6131. ​​The second end of the transmission rod 62 has a notch 621, and the second connecting rod 613 passes through the notch 621. The above structure facilitates the assembly between the transmission rod 62 and the locking frame 61.

[0062] like Figures 4 to 6 As shown, in this embodiment, the limiting mechanism 60 further includes a third reset member 64 disposed between the base 10 and the lower part of the transmission rod 62. The third reset member 64 abuts upward against the first end of the transmission rod 62 so that the second end of the transmission rod 62 drives the locking frame 61 from the locked position to the unlocked position and remains in the unlocked position. Specifically, in this embodiment, the third reset member 64 is a compression spring, which applies an upward force to the first end of the transmission rod 62, causing the second end of the transmission rod 62 to press down on the locking frame 61. The reset force of the third reset member 64 is greater than the reset force of the second reset member 63, so that when the pot assembly 20 leaves the base 10, the transmission rod 62 can overcome the reset force of the second reset member 63 under the drive of the third reset member 64, causing the locking frame 61 to move from the locked position to the unlocked position and remain in the unlocked position.

[0063] The specific steps for placing and removing the pot body assembly of the cooking appliance in this embodiment are as follows:

[0064] When the pot body assembly 20 is not placed in the base 10, the third reset member 64 abuts against the first end of the transmission rod 62, causing the first end of the transmission rod 62 to tilt upward. At this time, the second end of the transmission rod 62 drops and drives the locking frame 61 to press down the second reset member 63, so that the locking frame 61 can remain in the unlocked position.

[0065] As the pot assembly 20 is placed inside the base 10, the rotating shaft 221 pushes the switching structure 50 during the downward movement of the pot assembly 20, causing the transmission cylinder 41 to move from the driving position to the avoidance position in the lateral direction. After the pot assembly 20 is in place, the transmission cylinder 41 moves from the avoidance position to the driving position under the action of the first reset member 42. This enables the rotating shaft 221 and the transmission cylinder 41 to be inserted and engaged, thereby driving the stirring blade 22 to rotate through the driving mechanism 30 to achieve the stir-frying function. At the same time, when the pot assembly 20 moves to the position, it abuts against the protrusion 622, which applies a downward force to the first end of the transmission rod 62 to overcome the elastic force of the third reset member 64, causing the second end of the transmission rod 62 to rise to a position flush with the first end of the transmission rod 62 or the second end of the transmission rod 62 to tilt upward. Under the action of the upward reset force of the second reset member 63, the locking frame 61 rotates upward to the locking position, so that the locking frame 61 can lock the transmission cylinder 41 through the switching structure 50 in the future.

[0066] When it is necessary to remove the pot, the user operates the switching structure 50 to move the transmission cylinder 41 to the limit position. The locking frame 61 can lock the switching sleeve 51 and thus lock the transmission cylinder 41 to keep it in the limit position. At this time, the user can remove the pot. During the process of the user removing the pot body assembly 20, the upward movement of the pot body assembly 20 no longer applies force to the first end of the transmission rod 62. The first end of the transmission rod 62 tilts upward under the action of the third reset member 64, and the second end of the transmission rod 62 descends, allowing the locking frame 61 to switch to the unlock position.

[0067] It should be noted that during the process of placing the pot body assembly 20 inside the base 10, the rotating shaft 221 will push the switching structure 50 to drive the transmission cylinder 41 to move away from the rotating shaft 221 to the avoidance position, but the transmission cylinder 41 will not reach the limit position, so the locking frame 61 will not lock the transmission cylinder 41.

[0068] In this embodiment, a positioning protrusion is provided on the shaft portion 2211, and the pot assembly 20 also includes a rotating shaft cover 23 disposed on the pot body 21. The shaft portion passes through the pot body 21 and the rotating shaft cover 23, and the positioning protrusion is sandwiched between the pot body 21 and the rotating shaft cover 23, so that the shaft portion 2211 can only rotate relative to the pot body 21 and will not move relative to the pot body 21. The abutting mechanism is a protrusion 622 disposed at the first end of the transmission rod 62. When the pot assembly 20 is placed into the base 10, the rotating shaft cover 23 will abut against the protrusion 622 downward, thereby causing the transmission rod 62 to swing.

[0069] like Figures 1 to 3 as well as Figure 7 As shown, the first end of the first swing rod 54 is located below the pressing structure 52 and abuts against the pressing structure 52. The switching structure 50 also includes a linkage pin 541 disposed at the second end of the first swing rod 54 and a linkage groove 531 disposed at the end of the connecting rod 53 away from the switching sleeve 51. The linkage pin 541 is rotatably disposed in the linkage groove 531 and can slide along the linkage groove 531. When the user presses down on the pressing structure 52, the pressing structure 52 drives the first swing rod 54 to swing, and the linkage pin 541 located at the second end of the first swing rod 54 drives the connecting rod 53 to move in the lateral direction. The first swing rod 54 can convert the vertical movement of the pressing structure 52 into the lateral movement of the connecting rod 53. Specifically, the linkage groove 531 is a long groove structure (i.e., the length of the linkage groove 531 is greater than the width of the linkage groove 531). Through the mutual cooperation of the linkage pin 541 and the linkage groove 531, the swing of the first swing rod 54 is converted into the lateral movement of the connecting rod 53 and the switching sleeve 51, which can prevent jamming.

[0070] like Figure 2 and Figure 7As shown, the connecting rod 53 has a guide slope 532 on the side facing the pot assembly 20. When the pot assembly 20 is placed into the base 10, the rotating shaft 221 abuts against the guide slope 532, causing the switching sleeve 51 to move the transmission cylinder 41 from the driving position to the avoidance position. When lowering the pot assembly 20, the rotating shaft 221 can abut against the guide slope 532 and push the connecting rod 53, the switching sleeve 51, and the transmission cylinder 41 to move away from the rotating shaft 221, thereby avoiding the rotating shaft 221, so that the pot assembly 20 can be lowered smoothly and the rotating shaft 221 and the transmission cylinder 41 can be smoothly inserted and engaged.

[0071] like Figure 4 , Figure 6 and Figure 8 As shown, the transmission cylinder 41 includes a first transmission cylinder section 412, a second transmission cylinder section 413, and a connecting cylinder section 414 disposed between the first transmission cylinder section 412 and the second transmission cylinder section 413. When the transmission cylinder 41 is in the driving position, the first transmission cylinder section 412 is inserted into the rotating shaft 221. The end of the first transmission cylinder section 412 away from the second transmission cylinder section 413 has an end wall 415. A first reset member 42 is disposed between the end wall 415 and the output shaft 31. A protruding edge 411 is disposed on the outer side wall of the connecting cylinder section 414. When neither the rotating shaft 221 nor the switching sleeve 51 applies a force to the transmission cylinder 41 to move it to or maintain it in the avoidance position, the transmission cylinder 41 will be maintained in the driving position or moved from the avoidance position to the driving position and maintained in the driving position under the action of the first reset member 42. The transmission cylinder 41 is provided with a connecting hole 416. In this embodiment, the connecting hole 416 is a "D" shaped hole. The output shaft 31 passes through the connecting hole 416 and is anti-rotationally connected to the connecting hole 416. The output shaft 31 is provided with a sliding groove extending along its length, and the second transmission cylinder section 413 is provided with a mounting hole. The transmission cylinder 41 is telescopically connected to the output shaft 31 through a pin structure passing through the sliding groove and the mounting hole.

[0072] In embodiments not shown in the figures, two locking mechanisms different from those described above are also provided, as follows:

[0073] The first locking mechanism includes a third latch located at the second end of the reversing mechanism. The third latch has a simple structure, integrating it with the reversing mechanism. When the pot assembly is placed in or removed, the reversing mechanism drives the third latch to switch positions, thereby locking or unlocking the transmission cylinder, facilitating subsequent pot removal operations by the user.

[0074] The second locking mechanism includes a second swing rod and a fourth latch. The first end of the second swing rod is rotatably connected to the upright plate, and the fourth latch is located at the second end of the second swing rod. When the pot assembly is placed inside the base, the pot assembly abuts against the supporting mechanism, and the transmission rod pushes upward against the second swing rod, allowing the fourth latch to lock the transmission cylinder in a limited position. When the pot assembly leaves the base, the second swing rod falls, allowing the fourth latch to unlock the transmission cylinder. The structure of the second swing rod and the fourth latch is simple, eliminating the need for a reset component for the second swing rod. The fourth latch locks or unlocks the transmission cylinder directly by pushing against the second swing rod via the transmission rod, facilitating subsequent pot removal operations by the user.

[0075] The cooking appliance in this embodiment is a stir-fry machine, but it can also have other functions, such as pressure cooking.

[0076] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0077] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0078] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0079] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
