[0004] Background of the Invention

[0005] With the improvement of living standards, automated cooking appliances have gradually entered the public’s field of vision, and are popular with a lot of users due to their fool-proof operations. A stir-frying machine is one of them. A stir-frying machine uses a motor to drive a stirring blade to rotate, thereby realizing a function of stir-frying a food material.

[0006] In order to facilitate use by a user, the pot body of a cooking appliance is generally detachably arranged in a base body along a vertical direction, and the direction in which the user places and takes the pot is perpendicular to the extension direction of the rotation axis of a stirring blade. The patent CN218105619U discloses a cooking appliance comprising a magnetic induction switch, a retractable moving mechanism and a clutch driver. The retractable moving mechanism comprises a driving gear, a driven adjusting gear and a guide threaded member. When an upper lid covers a pot body, a magnet triggers the magnetic induction switch, a signal is then sent to an electronic control system, the electronic control system sends a control signal to the clutch driver. Under the driving force provided by the clutch driver, the driving gear rotates to drive the driven adjusting gear to move along the center line of the guide threaded member, so that a clutch driving part of a clutch transmission member is separated from a clutch driven part, thereby realizing the separation of a stirring blade from a stirring rotating device.

[0007] However, the above patent has a relatively high cost because it uses multiple transmission components.

[0008] Summary of the Invention

[0009] In order to solve the problem in the relevant art that a cooking appliance has a high cost, the present invention provides a cooking appliance.

[0010] The present invention provides a cooking appliance comprising: an outer shell; an inner pot which is detachably arranged on the outer shell and has a cooking chamber; a stirring assembly comprising a stirring blade, a driving member and a connecting member, wherein the stirring blade is rotatably arranged in the cooking chamber, the connecting member is movably arranged on the stirring blade or on a driving shaft of the driving member, and the connecting member has a driving position for connecting the driving shaft with the stirring blade and a separation position for separating the driving shaft from the stirring blade; and, an electromagnet arranged on the outer shell that is connected to the connecting member and capable of driving the connecting member to move between the separation position and the driving position.

Among an inner wall of the shift fork and an outer wall of the connecting member, one is provided with a second protrusion and the other is provided with a groove, the second protrusion being inserted into the groove. The cooperation between the second protrusion and the groove has the advantage of a simple connection structure.

[0019] Further, the induction member comprises a micro switch arranged on the outer shell, and the upper lid has a trigger bump arranged in a manner corresponding to the micro switch. When the upper lid covers the outer shell, the trigger bump is capable of triggering the micro switch, so that the working state of the micro switch switches, the electromagnet works accordingly, and the push rod extends out of the body by electromagnetic induction, thereby driving the connecting element to move.

[0042] Detailed Description of the Invention

[0043] The technical solutions in embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention or its application or use. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without inventive work are within the scope of protection of the present invention.

[0044] As shown in Figures 1 to 12, an embodiment of the present invention provides a cooking appliance. The cooking appliance comprises an outer shell 11 , an inner pot 12, a stirring assembly 30 and an electromagnet 42. The inner pot 12 is detachably arranged in the outer shell 11 and has a cooking chamber. The stirring assembly 30 comprises a stirring blade 31 , a driving member 32 and a connecting member 33. The stirring blade 31 is rotatably arranged in the cooking chamber. The connecting member 33 is movably arranged on the stirring blade 31 or on a driving shaft 321 of the driving member 32. The connecting member 33 has a driving position for connecting the driving shaft 321 with the stirring blade 31 and a separation position for separating the driving shaft 321 from the stirring blade 31 . The electromagnet 42 is arranged on the outer shell 11 . The electromagnet 42 is connected to the connecting member 33 and capable of driving the connecting member 33 to move between the separation position and the driving position.

[0045] By applying the technical solution of the present invention, the cooking appliance comprises the outer shell 11 , the inner pot 12, the stirring assembly 30 and the electromagnet 42. During use, by arranging the electromagnet 42 in a first state, the connecting member 33 is driven to move by means of the electromagnet 42 arranged on the outer shell 11 , so that the connecting member 33 moves from the separation position to the driving position, thus the driving shaft 321 is connected with the stirring blade 31 and the stirring blade 31 is driven to rotate by the driving member 32 through the connecting member 33 to stir food materials in the cooking chamber. After cooking ends, by switching the electromagnet 42 from the first state to a second sate, the connecting member 33 is driven to move in the opposite direction by means of the electromagnet 42, so that the connecting member 33 moves from the driving position to the separation position, thus the driving shaft 321 is separated from the stirring blade 31. At this time, a user can easily remove the inner pot 12 from the outer shell 11 . Compared to a method of driving a clutch driving part and a clutch driven part to disengage and engage by means of the cooperation between a guide threaded member and a gear, using the electromagnet 42 of the present application to drive the connecting member 33 to move has the advantages of a simple structure and low cost.

[0046] In the embodiment, the driving member 32 is a driving electric motor.

[0047] As shown in Figure 1 , the cooking appliance further comprises an upper lid 20 that can be arranged above the inner pot 12 or the outer shell 11 to cover it or be opened from it. When the upper lid 20 covers the outer shell 11 , the electromagnet 42 switches from a first state to a second state to drive the connecting member 33 to move from the separation position to the driving position; and when the upper lid 20 is opened from the outer shell 11 , the electromagnet 42 switches from the second state to the first state to drive the connecting member 33 to move from the driving position to the separation position. Achieving the switching of the states of the electromagnet 42 by opening and closing the upper lid 20 so as to drive the connecting member 33 to move has the advantage of being easy to operate.

[0048] In the embodiment, the cooking appliance further comprises an induction member arranged on the upper lid 20 or the outer shell 11. The induction member is capable of switching the electromagnet 42 between the first state and the second state. Using the induction member to switch the states of the electromagnet 42 has the advantages of easy material acquisition and low cost.

[0049] In the embodiment, the first state and the second state of the electromagnet 42 refer respectively to a power-on state and a power-off state of the electromagnet 42.

[0050] It should be noted that, when the induction member is arranged on the upper lid 20 and the upper lid 20 covers the outer shell 11 , the induction member can trigger the electromagnet 42 to change the operating state of the electromagnet 42. When the upper lid 20 is opened from the outer shell 11 , the electromagnet 42 returns to an initial operating state. The following two situations are included. First, when the upper lid 20 covers the outer shell 11 , the electromagnet 42 switches between a power-off state and a power-on state, at which time the push rod 422 moves relative to the body 421 under the effect of electromagnetic induction. When the upper lid 20 is opened from the outer shell 11 , the electromagnet 42 returns to an initial state, at which time the push rod 422 and the body 421 are provided with the reset spring used to drive the push rod 422 to move in an opposite direction. Second, when the upper lid 20 covers the outer shell 11 , electric current in the electromagnet 42 flows in a first direction; when the upper lid 20 is opened from the outer shell 11 , electric current in the electromagnet 42 flows in a second direction opposite to the first direction, thus realizing the switching of the movement direction of the push rod 422.

[0051] In the embodiment, the induction member is arranged on the upper lid 20. When the upper lid 20 covers the outer shell 11 , the induction member should be capable of coupling with the electromagnet 42, so that election current flows through the electromagnet 42, thus generating electromagnetic induction to drive the push rod 422 to move. In another embodiment where the induction member is arranged on the outer shell 11 , the upper lid 20 covers the outer shell 11 , the upper lid 20 should be capable of triggering the induction member so that electric current flows through the electromagnet 42.

[0052] The connecting member 33 can be arranged on the stirring blade 31 or on the driving shaft 321 , so long as it can move along the axial direction of the driving shaft 321 and realize the connection and separation between the two.

[0053] In the embodiment, the cooking appliance further comprises a control panel which is in signal connection respectively with the induction member and with the body 421. The control panel is capable of sending a control signal to the body 421 according to the operating state of the induction member. After the operating state of the induction member switches, it can be in signal connection with the control panel. Thus, the control panel can send a signal to the electromagnet 42 so that the electromagnet 42 generates electromagnetic induction.

[0054] As shown in Figures 6 and 7, the electromagnet 42 comprises the body 421 , the push rod 422 and the reset spring 423. The push rod 422 is movably arranged through the body 421 . The induction member is capable of being electrically connected to the body 421 . The push rod 422 is capable of driving the connecting element 33 to move relative to the driving shaft 321. When the upper lid 20 covers the outer shell 11 , the push rod 422 drives the connecting element 33 to move from the separation position to the driving position. By realizing the switching of the state of the electromagnet 42 by means of the induction member, the push rod 422 can be driven by electromagnet induction to move relative to the body 421 and thus drive the connecting element 33 to move.

[0055] As shown in Figures 6 and 7, the two ends of the push rod 422 both extend out of the body 421 . The reset spring 423 is sleeved on the push rod 422. One end of the reset spring 423 is connected to the push rod 422, and the other end of the reset spring 423 abuts against an outer wall of the body 421 . The reset spring 423 is capable of driving the push rod 422 to move when the upper lid 20 is opened from the outer shell 11 , so that the connecting element 33 is driven to move from the driving position to the separation position. By using the reset spring 423, the connecting member 33 can be automatically moved from the driving position to the separation position, which has the advantages of a simple structure and low cost.

[0056] The push rod 422 can directly drive the connecting member 33 to move relative to the driving shaft 321. Alternatively, it is possible to provide a transmission structure through which the connecting member 33 is driven to move relative to the driving shaft 321 . Specifically, the stroke of the push rod is from 3 mm to 11 mm.

[0057] In the embodiment, when the push rod 422 moves relative to the body 421 so that the connecting member 33 moves from the separation position to the driving position, the reset spring 423 is gradually compressed as the push rod 422 moves, thus generating a restoring force. When the upper lid 20 is opened from the outer shell 11 , the induction member is no longer able to continue to trigger the electromagnet 42 to operate and there is no electromagnetic induction between the body 421 and the push rod 422, so that the push rod 422 moves automatically under the effect of the restoring force and thus the connecting member 33 moves from the driving position to the separation position.

[0058] It should be noted that the electromagnet 42 is not limited to the above structure, so long as the connection between the electromagnet 42 and the connecting member 33 can be realized and the connecting member 33 can be driven to move between the separation position and the driving position.

[0059] As shown in Figures 3 and 5, the cooking appliance further comprises a sliding member 43. The sliding member43 comprises a sliding part 431 and a protruding part 432 arranged on an outer wall of the sliding part 431. The electromagnet 42 and the protruding part 432 are located on the same side of the driving member 32. The push rod 422 is drivingly connected to the protruding part 432, and the sliding part 431 is drivingly connected to the connecting member 33. As the electromagnet 42 and the connecting member 33 are arranged in a spaced apart manner, the driving connection between the push rod 422 and the connecting member 33 can be facilitated by means of the sliding member 43, so that the push rod 422 drives the connecting member 33 to move.

[0060] As shown in Figures 8 and 11 , in a first embodiment of the present application, the sliding part 431 comprises a sliding sleeve sleeved on an outer side wall of the connecting member33. A hook 4311 is provided on an outerwall of the sliding sleeve. A first protrusion 331 is provided on the outer wall of the connecting member 33. The first protrusion 331 is sandwiched between the hook 4311 and an end wall of the sliding sleeve. Using the sliding part 431 provided with the sliding sleeve has the advantage of a simple structure.

[0061] Specifically, when the push rod 422 extends out relative to the body 421 , by the hook 4311 abutting against the first protrusion 331 of the connecting member 33, the connecting member 33 can be pushed from the separation position to the driving position. When the push rod 422 retracts in the body 421 , by the end wall of the sliding sleeve abutting against the first protrusion 331 of the connecting member 33, the connecting member 33 can be pushed from the driving position to the separation position. As shown in Figures 3 and 8, the protruding part 432 comprises a first lug arranged on an outer wall of the sliding sleeve. The push rod 422 is connected to the first lug. Connecting the push rod 422 to the sliding member 43 by means of the first lug has the advantage of a simple structure.

[0062] In the first embodiment, an end of the push rod 422 close to the protruding part 432 is provided with a knurling texture. The protruding part 432 is provided with an insertion connection hole in which the knurling texture is inserted, so as to increase the friction between the two.

[0063] It should be noted that, during sliding of the sliding sleeve, the sliding sleeve can be sleeved on the stirring blade 31 , thereby permitting the connection between the connecting member 33 and the stirring blade 31 to be more stable, and making the rotation state more stable during operation.

[0064] As shown in Figure 9, in a second embodiment of the present application, the sliding part 431 comprises a shift fork. A first end of the shift fork is provided with a mounting notch. The protruding part 432 is a second lug provided at a second end of the shift fork. The shift fork is fitted onto an outer side wall of the connecting member 33 through the mounting notch. The push rod 422 is connected to the second lug. Using the shift fork to drive the connecting member 33 to move has the advantage of a simple structure.

[0065] In the second embodiment, among an inner wall of the shift fork and an outer wall of the connecting member 33, one is provided with a second protrusion, and the other is provided with a groove 4312. The second protrusion is inserted into the groove 4312. Cooperation between the second protrusion and the groove 4312 has the advantage of a simple connection structure.

[0066] Specifically, the shift fork comprises an arc shaped section, a first straight section and a second straight section. The first straight section and the second straight section are arranged respectively at two ends of the arc shaped section. The second lug is connected to an outer wall of the arc shaped section. The groove passes through the arc shaped section, the first straight section and the second straight section. The shift fork of the above structure has the advantage of being easy to machine.

[0067] In a third embodiment of the present application, the induction member comprises a micro switch arranged on the outer shell 11 , and the upper lid 20 has a trigger bump 21 arranged in a manner corresponding to the micro switch. When the upper lid 20 covers the outer shell 11 , the trigger bump 21 is capable of triggering the micro switch, so that the working state of the micro switch switches and thus the electromagnet works, and the push rod 422 extends out of the body 421 by electromagnetic induction, thereby driving the connecting element 33 to move.

[0068] In a fourth embodiment of the present application, the induction member comprise a reed switch arranged on the outer shell 11 , and the upper lid 20 has a magnetic element arranged in a manner corresponding to the reed switch. When the upper lid 20 covers the outer shell 11 , the magnetic element is capable of triggering the reed switch to switch the working state of the reed switch so that the electromagnet works.

[0069] As shown in Figures 5 and 11 , a plurality of inner teeth 311 are arranged at one end of the stirring blade 31 facing the connecting member 33, and a plurality of outer teeth 332 are arranged at one end of the connecting member 33 facing the stirring blade 31 . The plurality of outer teeth 332 and the plurality of inner teeth 311 engage with each other. By means of the cooperation between the plurality of inner teeth 311 and the plurality of outer teeth 332, when the push rod 422 drives the connecting member 33 to move, if the connecting member 33 and the stirring blade 31 cannot engage with each other because the inner teeth 311 and the outer teeth 332 are not aligned, the connecting member 33 can be driven to rotate by the driving member 32 so that the inner teeth 311 and the outer teeth 332 are aligned and engage with each other.

[0070] In the embodiment, an end of the stirring blade 31 oriented towards the connecting member 33 is connected to a gear sleeve at which a plurality of inner teeth 311 are arranged.

[0071] In this embodiment, the electromagnet 42 and the connecting member 33 are located at a side of the inner pot 12, the electromagnet 42 is located above the connecting member 33 and the driving member 32.

[0072] As shown in Figure 11 , the connecting member 33 comprises a connecting sleeve slidably sleeved on the driving shaft 321. The stirring assembly 30 further comprises a position limiting pin 34. The driving shaft 321 is provided with an elongated hole 3211 extending along its axial direction. A position limiting hole 334 is provided on the connecting sleeve. The position limiting pin 34 is inserted through the elongated hole 3211 and the position limiting hole 334. The position limiting pin 34 is capable of sliding along the extension direction of the elongated hole 3211. With the above structure, the connecting sleeve can rotate along with the driving shaft 321 by means of the position limiting pin 34, and in the meanwhile, the connecting sleeve can move along the axial direction of the driving shaft 321 by means of the elongated hole 3211.

[0073] Specifically, when the connecting member 33 is in the driving position, the depth by which the connecting member 33 is inserted into the gear sleeve of the stirring blade 31 is from 4 mm to 9 mm. When the connecting member 33 is in the separation position, the distance between the connecting member 33 and the gear sleeve is from 0.3 mm to 5 mm.

[0074] In the embodiment, the stirring assembly 30 further comprises a mounting frame 35 which is provided with a mounting chamber 351 and an electromagnet mounting chamber 352. The driving member 32 is arranged in the mounting chamber 351 for driving member. The electromagnet 42 is arranged in the electromagnet mounting chamber 352. Using the mounting frame 35 to arrange the driving member 32 and the electromagnet 42 has the advantages of a simple structure and being easy to arrange.

[0075] In this embodiment, the electromagnet 42, the driving member 32 and the connecting member 33 are all arranged in the outer shell 11 and located at a side of the inner pot 12. The driving member 32 and the connecting member 33 are both located below the electromagnet 42. The above structural arrangement can reduce the height of the cooking appliance, facilitate operations by a user and facilitate the transportation and packaging of the cooking appliance.

[0076] In the embodiment, the cooking appliance comprises a stir frying machine.

[0077] Below is an introduction in conjunction with the specific operating process of the cooking appliance:

[0078] When the upper lid 20 is arranged on the outer shell 11 to cover it, the trigger bump 21 of the upper lid 20 triggers the micro switch on the outer shell 11 , alternatively the magnetic member of the upper lid 20 triggers the reed switch on the outer shell 11 , so that the working state of the micro switch or the reed switch switches and the body 421 of the electromagnet 42 is power-on. Thus the push rod 422 moves relative to the body 421 through electromagnetic induction, and the push rod 422 drives the sliding member 43 to move. The sliding member 43 thus drives the connecting member 33 to move along the axial direction of the driving shaft 321 and the connecting member 33 moves from the separation position to the driving position. In this way, the driving member 32 is connected to the stirring blade 31 through the connecting member 33, so as to drive the stirring blade 31 to rotate, realizing the stirring of food materials in the stir frying machine. In addition, when the push rod 422 moves relative to the body 421 , the reset spring 423 is compressed. When the upper lid 20 is separated from the outer shell 11 , the elastic force provided by the reset spring 423 moves the push rod 422, and the push rod 422 drives the sliding member 43 to move. The sliding member 43 thus drives the connecting member 33 to move from the driving position to the separation position, realizing the separation of the connecting member 33 from the stirring blade 31. At this time, the inner pot 12 can be taken out of the outer shell 11.
