[0002] With the improvement of living standards, automated cooking equipment has gradually entered the public's field of vision, and has been loved by the majority of users due to its fool-proof operation. Among them, the stir-frying machine is one of them. The stir-frying machine uses a motor to drive the stirring blade to rotate, thereby realizing the function of stir-frying the ingredients.

[0003] In order to facilitate the use of users, the pot body of the cooking utensil is generally removably arranged in the base body along the vertical direction. The direction in which the user takes and places the pot is perpendicular to the extension direction of the rotation axis of the stirring component. Therefore, when the user takes and places the pot, it is generally necessary to disengage the stirring component from the corresponding driving structure.

[0004] At present, the cooking utensils in the related art can use a button structure to disengage the driving structure from the stirring component. When the user needs to take out the pot, he only needs to press the button to take the pot out of the base. However, the above cooking utensils also have disadvantages. The user needs to keep pressing the button to keep the driving structure and the stirring component in the disengaged state, that is, the user only has one hand left to take out the pot, which is inconvenient to operate, especially when there is a lot of food in the pot, the user is very difficult to operate. Summary of the invention

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] like Figures 1 to 24As shown, an embodiment of the present invention provides a cooking utensil, which includes an outer shell 11, an inner pot 12, an upper cover 20, a stirring assembly 30 and an advance and retreat blade assembly 40. The inner pot 12 is detachably arranged on the outer shell 11, and the inner pot 12 has a cooking cavity; the upper cover 20 is detachably arranged on the upper part of the inner pot 12; the stirring assembly 30 includes a stirring blade 31, a driving member 32 and a connecting member 33, the stirring blade 31 is rotatably arranged on the inner pot 12 or the upper cover 20 around its transverse axis, and the connecting member 33 is movably arranged on the outer shell 11 or the inner pot 12, the connecting member 33 has a driving position for connecting the driving shaft 321 of the driving member 32 with the stirring blade 31 and a separation position for separating the driving shaft 321 from the stirring blade 31; the advance and retract blade assembly 40 includes a reset member 41 that can provide a restoring force for the connecting member 33. When the upper cover 20 is covered on the outer shell 11, the upper cover 20 can serve as a driving source to drive the connecting member 33 to move from the separation position to the driving position. When the upper cover 20 is opened from the outer shell 11, the reset member 41 drives the connecting member 33 to move from the driving position to the separation position.

[0057] The cooking device according to the technical solution of the present invention includes a shell 11, an inner pot 12, an upper cover 20, a stirring assembly 30 and a knife advance and retreat assembly 40. When the upper cover 20 is placed on the shell 11, the upper cover 20 can act as a driving source to drive the connecting member 33 to move, so that it moves from the separation position to the driving position, so that the driving shaft 321 and the stirring knife 31 are connected, and then the driving member 32 drives the connecting member 33 to rotate, and the connecting member 33 drives the stirring knife 31 to flip in the cooking cavity to achieve stirring of the food. When the upper cover 20 is opened from the shell 11, the restoring force provided by the reset member 41 can drive the connecting member 33 to move in the opposite direction, so that it moves from the driving position to the separation position, so that the driving shaft 321 and the stirring knife 31 are separated. At this time, the inner pot 12 can be easily taken out of the shell 11.

[0058] The upper cover 20 can serve as a driving source, which means that the upper cover 20 can drive the connecting member 33 to move by means of a mechanical structure.

[0059] In other embodiments, magnetic components may be provided on both the upper cover 20 and the outer shell 11 , and the magnetic attraction or repulsion of the magnetic components may be utilized to drive the connecting component 33 to move.

[0060] It should be noted that the upper cover 20 , as a driving source, can either directly drive the connecting member 33 to move, or a transmission structure can be provided, and the upper cover 20 drives the connecting member 33 to move through the transmission structure.

[0061] In this embodiment, the connecting member 33 is disposed on the driving shaft 321 and moves along the axial direction of the driving shaft 321. The connecting member 33 can be disposed on either the mixing blade 31 or the driving shaft 321, as long as the connecting member 33 can move along the axial direction of the driving shaft 321 to connect the mixing blade 31 and the driving shaft 321.

[0062] In other embodiments, the connecting member 33 can move perpendicular to the axial direction of the driving shaft 321. In this case, the driving member 32 can be arranged vertically in the outer shell 11, the stirring blade 31 can be arranged horizontally on the inner pot 12, and the connecting member 33 can be arranged vertically on the driving shaft 321. Bevel gears that can mesh are respectively sleeved on the connecting member 33 and the stirring blade 31. When the upper cover 20 is covered on the outer shell 11, the connecting member 33 is driven to move vertically by the upper cover 20 to connect the stirring blade 31 and the driving shaft 321. Alternatively, the connecting member 33 is arranged horizontally on the stirring blade 31, and bevel gears that can mesh are respectively sleeved on the connecting member 33 and the driving shaft 321. When the upper cover 20 is covered on the outer shell 11, the connecting member 33 is driven to move horizontally by the upper cover 20 to connect the stirring blade 31 and the driving shaft 321.

[0063] The stirring blade 31 can also be arranged on the upper cover 20. In this case, the connecting member 33 can be arranged on the driving shaft 321. The driving member 32 can be arranged horizontally or vertically. When the upper cover 20 is covered on the housing 11, the connecting member 33 is driven by the upper cover 20 to move so as to connect the stirring blade 31 and the driving shaft 321.

[0064] In this embodiment, the reset member 41 is a reset spring. In other embodiments, the reset member 41 can also be configured as a reset motor or a mechanical button. The reset motor or the user pressing the mechanical button drives the connector 33 to move.

[0065] like Figure 3 , Figure 6 , Figure 8 as well as Fig.14 As shown, the advance and retract blade assembly 40 also includes a lever 42, which is swingably disposed on the housing 11, and has a first matching portion and a second matching portion, which are respectively located on both sides of the swing center of the lever 42, and the upper cover 20 can drive and match the lever 42 through the first matching portion to make the lever 42 swing, and the lever 42 can drive and connect with the connecting member 33 through the second matching portion to move the connecting member 33. By swinging the lever 42 in the housing 11, the first matching portion and the second matching portion can have opposite moving directions, and then reversing can be achieved. When the upper cover 20 drives and matches with the first matching portion, the second matching portion moves in the opposite direction, and then drives the connecting member 33 to move, so that the connecting member 33 moves from the separation position to the driving position.

[0066] In other embodiments, the transmission structure may not be provided with the lever 42, and the upper cover 20 may be directly used to drive the transmission structure, such as a slider, and the transmission structure drives the connecting member 33 to move from the separation position to the driving position.

[0067] It should be noted that the first matching portion and the second matching portion can be arranged at the end of the lever 42 or at a position close to the swing center of the lever 42, and both of the above methods can achieve the effect of reversing. In this embodiment, the first matching portion and the second matching portion are both arranged at the end of the lever 42.

[0068] In this embodiment, the lever 42 is arranged to swing in the lateral direction. In other embodiments, the lever 42 can be arranged to swing in the vertical direction.

[0069] In this embodiment, a slider is movably connected to the first mating portion of the lever 42, and the slider extends to the outside of the side wall of the housing 11, and the slider is driven by the upper cover 20 to swing the lever 42. Of course, it is also possible to extend the end of the lever 42 to the outside of the side wall of the housing 11 without providing a slider, and directly abut the end of the lever 42 through the upper cover 20 to swing the lever 42.

[0070] In other embodiments, a chain and a sprocket can be used to set a transmission member on one side of the chain and set the connecting member 33 on the other side of the chain. The transmission member is driven by the upper cover 20 so that the movement directions of the transmission member and the connecting member 33 are opposite, thereby realizing that the connecting member 33 moves from the separation position to the driving position.

[0071] The lever 42 may be disposed inside the outer shell 11 or on the outer wall of the inner pot 12 , as long as it does not affect the removal of the inner pot 12 from the outer shell 11 .

[0072] like Figure 3 , Figure 6 , Figure 8 as well as Fig.14 As shown, the blade advancing and retracting assembly 40 further includes a slider 43 disposed in the housing 11, and the upper cover 20 can drive the slider 43 to slide, and the slider 43 is movably connected to the lever 42. The upper cover 20 can drive the slider 43 to move in a direction away from the mixing blade 31, and then the slider 43 drives the lever 42 to swing in the housing 11, so that the lever 42 drives the connecting member 33 to move in a direction close to the mixing blade 31, so that it moves from the separation position to the driving position.

[0073] When the lever 42 is disposed in the housing 11, the slider 43 can slide in the housing 11 and can pass through the housing 11 to cooperate with the upper cover 20. When the lever 42 is disposed in the inner pot 12, the slider 43 can be disposed on the outer wall of the inner pot 12.

[0074] like Figure 2As shown, the upper cover 20 is provided with a pressing block 21, and one end of the slider 43 facing the pressing block 21 is provided with an inclined surface 431. When the upper cover 20 is covered on the housing 11, the end of the pressing block 21 facing the slider 43 abuts against the inclined surface 431 to drive the slider 43 to slide. By virtue of the pressing block 21 being able to abut against the inclined surface 431, when the upper cover 20 is gradually covered on the housing 11, the pressing block 21 can gradually press on the inclined surface 431 and drive the slider 43 to move.

[0075] It should be noted that a vertical surface 435 is also provided on the slider 43, and the vertical surface 435 is connected to the bottom of the inclined surface 431. After the upper cover 20 is covered on the outer shell 11 and the slider 43 slides into place, the pressure block 21 abuts against the vertical surface 435 to prevent the pressure block 21 and the inclined surface 431 from cooperating to generate an upward force on the upper cover 20 and lift the upper cover 20.

[0076] In this embodiment, the angle between the inclined surface 431 and the horizontal plane is between 35° and 70°. The projected length of the inclined surface 431 on the horizontal plane is between 3 mm and 10 mm.

[0077] like Figure 2 and Figure 5 As shown, the blade advance and retract assembly 40 further includes a sleeve 44 slidably disposed in the housing 11, the sleeve 44 is movably connected to a side of the lever 42 away from the slider 43, and the sleeve 44 is drivingly connected to the connecting member 33. By movably connecting the sleeve 44 to the lever 42, the connecting member 33 is driven to move by the sleeve 44, which has the advantage of a simple structure.

[0078] In other embodiments, other structures may be provided at the second end of the lever 42, such as a slidable connector, with one end of the connector hinged to the lever 42 and the other end of the connector inserted into the connector 33 to drive the connector 33 to move.

[0079] The sliding sleeve 44 is drivingly connected to the connecting member 33 , which means that the sliding sleeve 44 can provide driving force for the connecting member 33 to drive the connecting member 33 to move.

[0080] When the lever 42 is disposed in the outer shell 11 , the sliding sleeve 44 can slide in the outer shell 11 . When the lever 42 is disposed in the inner pot 12 , the sliding sleeve 44 can be disposed on the outer wall of the inner pot 12 .

[0081] In this embodiment, the lever 42 is swingably disposed in the housing 11 and is located at the side of the inner pot 12, the slider 43 is slidably disposed in the housing 11 and can pass through the housing 11, and the sliding sleeve 44 is slidably disposed in the housing 11. With the above-mentioned structural arrangement, the side space of the housing 11 can be fully utilized to reduce the space occupied by the cooking utensil, facilitate the arrangement, and reduce the height size of the cooking utensil.

[0082] Specifically, the lever 42 is horizontally arranged in the transverse direction, and the slider 43 and the sliding sleeve 44 are hinged at two ends of the lever 42 respectively.

[0083] like Figure 7 and Figure 8 As shown, a bracket 111 is provided in the housing 11, a hinge shaft 1111 extending vertically is provided on the bracket 111, a lever 42 is hingedly provided at the hinge shaft 1111, and a slider 43 and a sliding sleeve 44 are both slidably provided in the horizontal direction on the bracket 111. By providing the bracket 111, on the one hand, the arrangement of the lever 42 can be facilitated, and on the other hand, during the swinging process of the lever 42, the slider 43 and the sliding sleeve 44 can be guided so that the slider 43 and the sliding sleeve 44 can both move in the horizontal direction.

[0084] In this embodiment, the reset member 41 includes a first spring, and two ends of the first spring are respectively in contact with the slider 43 and the bracket 111 .

[0085] Specifically, a fixing column 432 is provided at one end of the slider 43, and the first spring is sleeved on the fixing column 432. The two ends of the first spring are respectively in contact with the outer wall of the slider 43 and the bracket 111. With the above structure, the fixing column 432 can guide the first spring so that the first spring will not be skewed.

[0086] When the pressing block 21 drives the slider 43 to move away from the stirring blade 31, the first spring is gradually compressed to generate a restoring force. When the upper cover 20 is opened from the housing 11, the restoring force of the first spring can drive the slider 43 to move toward the stirring blade 31.

[0087] like Figure 2 , Fig.12 as well as Fig.13 As shown, the bracket 111 is provided with a drive member installation cavity 1112, a first slide groove 1113 and a second slide groove 1114, the drive member 32 is located in the drive member installation cavity 1112, the first slide groove 1113 and the second slide groove 1114 are respectively located on both sides of the bracket 111 and extend in the transverse direction, the slider 43 is slidably arranged in the first slide groove 1113, and the slide sleeve 44 is slidably arranged in the second slide groove 1114. The bracket 111 with the above structure can not only carry the drive member 32, but also carry the slider 43 and the slide sleeve 44, and can guide the slider 43 and the slide sleeve 44, thereby improving the integration of the bracket 111. In addition, the first slide groove 1113 can be used to limit the slider 43, so as to prevent the slider 43 from tilting due to the force when the upper cover 20 abuts against the slider 43.

[0088] In this embodiment, a sleeve pressure plate and a slider pressure plate are further provided on the bracket 111 . The slider pressure plate cover is disposed on the first slide groove 1113 , and the sleeve pressure plate cover is disposed on the second slide groove 1114 .

[0089] like Fig.10 and Fig.16 As shown, the sliding sleeve 44 includes a sleeve section 441 and a sliding section 442 connected to the outer wall of the sleeve section 441. The sleeve section 441 is sleeved on the outer side of the connecting member 33 and is drivingly connected to the connecting member 33. The sliding section 442 is slidably arranged on the bracket 111 and is hinged to the lever 42. The sliding sleeve 44 with the above structure can form a guide match with the bracket 111 by using the sliding section 442, and can drive the connecting member 33 to move by using the sleeve section 441, which has the advantage of simple structure.

[0090] like Figures 8 to 10 As shown, in this embodiment, the slider 43 is provided with a first rotating shaft 433, the sleeve 44 is provided with a second rotating shaft 443, and the two ends of the lever 42 are respectively provided with a first strip groove 421 and a second strip groove 422. The first rotating shaft 433 is inserted in the first strip groove 421 and can slide along the extension direction of the first strip groove 421, and the second rotating shaft 443 is inserted in the second strip groove 422 and can slide along the extension direction of the second strip groove 422. With the above structure, the slider 43 can drive the lever 42 to swing in the housing 11 by using the first rotating shaft 433. The sleeve 44 can be driven to slide when the lever 42 swings by using the second rotating shaft 443. By using the first strip groove 421, during the sliding process of the slider 43, the first end of the lever 42 can slide relative to the slider 43, so that the distance between the swing centers of the slider 43 and the lever 42 remains unchanged, so that no force away from the hinge axis 1111 is generated between the slider 43 and the lever 42, and the slider 43 slides more smoothly along a straight line. By using the second strip groove 422, during the swing process of the lever 42, the second end of the lever 42 can slide relative to the sleeve 44, so that the distance between the swing centers of the sleeve 44 and the lever 42 remains unchanged, so that no force away from the hinge axis 1111 is generated between the sleeve 44 and the lever 42, and the sleeve 44 slides more smoothly along a straight line.

[0091] In other embodiments, Figures 14 to 16 As shown, the slider 43 is provided with a first insertion hole 434, the sleeve 44 is provided with a second insertion hole 444, the first end of the lever 42 is inserted into the first insertion hole 434 and can slide in the first insertion hole 434, and the second end of the lever 42 is inserted into the second insertion hole 444 and can slide in the second insertion hole 444. The above arrangement has the advantage of simple structure.

[0092] like Figure 2 and Fig.17As shown, the connecting member 33 includes a connecting sleeve, which can be slidably mounted on the driving shaft 321. The outer wall of the connecting sleeve is provided with an annular protrusion 331. The end wall of the sliding sleeve 44 abuts against the side wall of the annular protrusion 331 facing the stirring blade 31, so that the connecting member 33 moves from the driving position to the separation position. The connecting member adopting the above structure has the advantages of simple structure and easy setting.

[0093] like Figure 2 and Figure 8 As shown, the stirring assembly 30 also includes a stop pin 34 and a second spring 35. The driving shaft 321 is provided with a strip hole 3211 extending along its axial direction. The connecting sleeve is provided with a stop hole 332. The stop pin 34 is inserted through the strip hole 3211 and the stop hole 332. The stop pin 34 can slide along the extension direction of the strip hole 3211. The second spring 35 is sleeved on the driving shaft 321. The two ends of the second spring 35 are respectively in contact with the driving shaft 321 and the connecting sleeve, so that the connecting member 33 moves from the separation position to the driving position. The second spring 35 can provide a restoring force. When the connecting sleeve moves from the driving position to the separation position, the second spring 35 is gradually compressed. When the sliding sleeve 44 moves toward the direction close to the stirring blade 31, the restoring force of the second spring 35 can be used to drive the connecting sleeve from the separation position to the driving position. The stop pin 34 can be used to make the connecting sleeve slide along the extension direction of the strip hole 3211 to form a guiding effect on the connecting sleeve.

[0094] In other embodiments, a groove may be provided on one of the connecting sleeve and the sliding sleeve 44, and a protrusion may be provided on the other of the connecting sleeve and the sliding sleeve 44. The protrusion may be inserted into the groove. By cooperating with the groove and the protrusion, the connecting sleeve may be driven to move when the sliding sleeve 44 moves toward the stirring blade 31 or away from the stirring blade 31, and there is no need to provide a second spring 35.

[0095] In this embodiment, when the connecting member 33 is in the driving position, the depth of the connecting member 33 inserted into the tooth sleeve of the stirring blade 31 is between 4 mm and 9 mm. When the connecting member 33 is in the separation position, the distance between the connecting member 33 and the tooth sleeve is between 0.3 mm and 5 mm.

[0096] The following is an explanation of the specific working process of the cooking appliance:

[0097] When the upper cover 20 is covered on the outer shell 11, the pressing block 21 can be used to abut against the inclined surface 431 of the slider 43, thereby driving the slider 43 to move in the direction away from the stirring knife 31. During the movement of the slider 43, the first spring is compressed, and at the same time, the lever 42 is driven to swing relative to the bracket 111. The lever 42 drives the sliding sleeve 44 to move in the direction close to the stirring knife 31. Under the elastic force of the second spring 35, the connecting member 33 moves in the direction close to the stirring knife 31, so that the stirring knife 31 is connected to the driving shaft 321. Under the driving force of the driving member 32, the stirring knife 31 can be driven to flip in the cooking cavity through the connecting member 33. When the upper cover 20 is opened from the outer shell 11, under the action of the restoring force of the first spring, the slider 43 moves toward the direction close to the stirring blade 31, and at the same time drives the lever 42 to swing relative to the bracket 111, and the bracket 111 drives the sliding sleeve 44 to move in the direction away from the stirring blade 31, and the sliding sleeve 44 drives the connecting piece 33 to move in the direction away from the stirring blade 31 through the annular protrusion 331, so that the stirring blade 31 is separated from the driving shaft 321, and the inner pot 12 can be taken out of the outer shell 11.

[0098] like Figure 5 and Fig.17 As shown, the end of the stirring blade 31 facing the connecting member 33 is provided with a plurality of inner teeth 311, and the end of the connecting member 33 facing the stirring blade 31 is provided with a plurality of outer teeth 333, and the plurality of outer teeth 333 mesh with the plurality of inner teeth 311. When the connecting member 33 moves to the driving position, if the connecting member 33 and the stirring blade 31 cannot mesh because the inner teeth 311 and the outer teeth 333 are not aligned, the driving member 32 can drive the connecting member 33 to rotate so that the inner teeth 311 and the outer teeth 333 are aligned and meshed.

[0099] Among them, a plurality of internal teeth 311 are arranged on the gear sleeve.

[0100] like Fig. 20 and Fig.21 As shown, the cooking utensil is provided with a plug-in structure 50, which includes a slot 51 and a plug-in protrusion 52. The slot 51 is provided at one of the upper cover 20 and the outer shell 11, and the plug-in protrusion 52 is provided at the other of the upper cover 20 and the outer shell 11. When the upper cover 20 is covered on the outer shell 11, the plug-in protrusion 52 is inserted in the slot 51, and the upper cover 20 abuts against the slider 43. When the upper cover 20 is covered on the outer shell 11, the plug-in structure 50 can be used to position the upper cover 20 to prevent the upper cover 20 from being unable to be installed in place due to the reaction force of the slider 43 on the upper cover 20.

[0101] In other embodiments, the upper cover 20 may also be hingedly disposed on the outer shell 11 , as long as the pressing block 21 can drive the sliding block 43 to move.

[0102] like Fig.21 and Fig.23 As shown, the slot 51 is arranged on the housing 11, the notch of the slot 51 is arranged toward the inner pot 12, and the slot 51 has a guide slope 511 arranged upwardly inclined. When the plug-in protrusion 52 is inserted into the slot 51, the guide slope 511 can facilitate the operation of the user.

[0103] In other embodiments, the notch of the slot 51 may be arranged upward, so that the insertion protrusion 52 can be conveniently inserted into the slot 51 without providing a guiding inclined surface.

[0104] like Figure 20 to Figure 22 As shown, the cooking utensil is provided with a snap-fit ​​structure 60, the plug-in structure 50 and the snap-fit ​​structure 60 are respectively located on opposite sides of the cooking utensil, and the snap-fit ​​structure 60 includes a snap-fitting snap-fitting groove 61 and a snap-fitting protrusion 62, the snap-fitting groove 61 is provided on one of the upper cover 20 and the outer shell 11, and the snap-fitting protrusion 62 is provided on the other of the upper cover 20 and the outer shell 11. By matching the plug-in structure 50 and the snap-fitting structure 60, the upper cover 20 and the outer shell 11 can be fixed to prevent the upper cover 20 from moving laterally.

[0105] In this embodiment, the cooking appliance includes a cooking machine.
