In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0045] like Figures 1 to 3 , Figure 8 and Fig. 9 As shown, the cooking utensil of the first embodiment includes a base 10, a first container 21, a second container 22, and a first driving mechanism. The first container 21 and the second container 22 can be installed in the base 10, and the second container 22 has a stirring structure 90. The first driving mechanism is arranged on the base 10, and the first driving mechanism includes a motor 31 and a transmission member 32 connected to the motor 31. In the first embodiment, the motor 31 is movably arranged on the base 10 to drive the transmission member 32 to move, and the transmission member 32 has an avoidance position to avoid the first container 21 or a docking position to dock with the stirring structure 90; the heating device 13 is arranged in the base 10.

[0046] By applying the technical solution of the first embodiment, the motor 31 can be movably arranged on the base 10 to drive the transmission member 32 to move, and the transmission member 32 has an avoidance position to avoid the first container 21 or a docking position to dock with the stirring structure 90. When the first container 21 is installed on the base 10, the transmission member 32 is in the avoidance position, and the transmission member 32 can avoid the first container. The transmission member 32 will not interfere with the first container 21. When the second container 22 with the stirring structure 90 is installed on the base 10, the transmission member 32 is in the docking position, and the motor 31 can drive the transmission member 32 to rotate to drive the stirring structure 90 to rotate. Therefore, the cooking utensil of the first embodiment can use both the first container without the stirring structure and the second container with the stirring structure, so that the cooking utensil can have multiple cooking functions. Therefore, the technical solution of the first embodiment effectively solves the problem that the lower coupler in the related art will interfere with the ordinary container, resulting in the inability to use the ordinary container.

[0047] It should be noted that: the base is generally a pot body or a base, and the container can be an inner pot or a cup body. The above-mentioned "avoidance" means that the transmission member can move to make room, such as moving down (when the transmission member is set below the container) or moving sideways (when the transmission member is set on the side of the container). In this way, when the first container is placed in the base, it will no longer interfere with the transmission member. The above-mentioned "docking" means that the transmission member and the stirring structure can be plugged in and matched and can rotate synchronously.

[0048] In the first embodiment, the stirring structure is arranged at the bottom of the second container, and the transmission member is located at the bottom of the base. In other embodiments not shown in the figures, the stirring structure can also be arranged at the side of the second container, and correspondingly, the transmission member is located at the side of the base.

[0049] In the first embodiment, the cooking appliance further comprises a second driving mechanism, which drives the motor 31 to move. The second driving mechanism is provided to facilitate the control of the movement of the motor.

[0050] like Figure 7 As shown, in the first embodiment, the second driving mechanism includes a magnetic mechanism 60. Under the action of the magnetic mechanism 60, the motor 31 can directly drive the transmission member 32 to move, so that the transmission member 32 can avoid or cooperate with the stirring structure 90. The magnetic mechanism 60 has a simple structure, reliable operation and low cost.

[0051] Of course, in other embodiments not shown in the figures, the second driving mechanism includes a controller, a button connected to the controller, and an actuator connected to the controller, the actuator can drive the motor to move, and the controller controls the actuator according to the signal of the button to control the movement of the motor. As another feasible implementation, the second driving mechanism may include an elastic member arranged between the base and the motor, under the action of the elastic member, the motor can move and can drive the transmission member to move.

[0052] like Figure 4 , Figure 7 , Fig.10 and Fig.13 As shown, in the first embodiment, the magnetic mechanism 60 includes a first magnetic member 61, and the first magnetic member 61 can drive the motor 31 to move toward the first container or the second container. When the first magnetic member 61 applies magnetic force to the motor, the movement of the motor 31 is achieved. The first magnetic member 61 has a simple structure and is easy to achieve. The movement of the motor 31 and the transmission member 32 away from the first container 21 or the second container 22 can be achieved by pressing down the first container 21.

[0053] like Figure 4 , Figure 7 , Fig.10 and Fig.13As shown, in the first embodiment, the magnetic mechanism 60 includes a second magnetic member 62, and the motor 31 can be driven by the second magnetic member 62, and the second magnetic member 62 can drive the motor 31 to move in a direction away from the first container or the second container. When the second magnetic member 62 applies a magnetic force to the motor, the movement of the motor is achieved, and the force application process is reliable. The second magnetic member 62 and the first magnetic member 61 drive the motor 31 to move respectively, so that the motor 31 can move as required. The first magnetic member 61 is located above the motor 31, and the second magnetic member 62 is located below the motor 31. The second magnetic member 62 can apply a magnetic force to the motor 31, and the motor 31 can move downward under the action of the second magnetic member 62. The first magnetic member 61 can apply a magnetic force to the motor 31, and the motor 31 can be in a position after moving upward under the action of the first magnetic member 61.

[0054] like Figure 4 , Figure 7 , Fig.10 and Fig.13 As shown, in the first embodiment, the motor 31 is provided with a third magnetic member and a fourth magnetic member, the first magnetic member 61 cooperates with the third magnetic member, and the second magnetic member 62 cooperates with the fourth magnetic member to drive the motor 31 to move. The driving motor 31 can move upward. The first magnetic member 61 cooperates with the third magnetic member, and the second magnetic member 62 cooperates with the fourth magnetic member, so that the process of driving the motor 31 to move is more accurate and reliable.

[0055] It should be noted that, in the first embodiment, the first magnetic member 61 cooperates with the third magnetic member, and the second magnetic member 62 cooperates with the fourth magnetic member. The specific cooperation relationship is as follows:

[0056] When the first magnetic part 61 cooperates with the third magnetic part to produce a magnetic attraction, there is no magnetic attraction between the second magnetic part 62 and the fourth magnetic part; when the second magnetic part 62 cooperates with the fourth magnetic part to produce a magnetic attraction, there is no magnetic attraction between the first magnetic part 61 and the third magnetic part. In this way, when the first magnetic part cooperates with the third magnetic part, the influence of the cooperation between the second magnetic part and the fourth magnetic part is avoided. The first magnetic part and the second magnetic part of embodiment one are preferably electromagnets. The third magnetic part and the fourth magnetic part are preferably permanent magnets.

The first magnetic member 61 cooperates with the third magnetic member magnetic mechanism and the second magnetic member 62 cooperates with the fourth magnetic member to drive the guide member 80 to move in the guide groove 81 to drive the housing 70 to move up or down. The guide member 80 cooperates with the guide groove 81, so that the guide member 80 can move along the track of the guide groove 81, so that the process of the housing 70 moving up or down is more stable.

[0059] like Figure 4 , Figure 7 , Fig.10 and Fig.13 As shown, the guide member 80 includes two racks 82 arranged opposite to each other and a gear 83 arranged between the two racks 82, and the gear 83 is connected to the housing 70. In this way, the gear 83 is clamped between the two racks 82, and the two racks 82 clamp the gear 83 to move upward or downward. There is no relative movement between the rack 82 and the gear 83. The magnetic mechanism 60 drives the rack 82 to move in the guide groove 81 to drive the housing 70 to move up or down.

The motor is located below the fixing plate 51, and the guide slot 81 is arranged on the pillar 52. In this way, the position of the guide slot 81 corresponds to the position of the motor, which facilitates the arrangement of the rack 82 and the gear 83 structure.

[0061] like Figure 4 , Figure 7 , Fig.10 , Figures 13 to 16 As shown, the pillar 52 is bent, and the pillar 52 includes a first column section 521 and a second column section 522 arranged at intervals, and a connecting section 523 connected between the first column section 521 and the second column section 522. The first column section 521, the second column section 522 and the connecting section 523 together form an installation space, which is convenient for accommodating the housing 70 and the guide member 80. The guide groove 81 is provided in the first column section 521, and the rack 82 is provided with a stopper 821 that cooperates with the connecting section 523.

[0062] like Figure 4 and Fig.10 As shown, a baffle 74 is provided on the side wall of the shell 70, one end of the baffle 74 is connected to the shell 70, and the other end is a free end, and there is an accommodation distance between the free end and the side wall of the shell 70, and a first through hole is provided on the free end, and a second through hole corresponding to the first through hole is provided on the side wall of the shell 70, one end of the axle of the gear 83 is inserted into the first through hole, and the other end of the axle of the gear 83 is inserted into the second through hole, so that the gear 83 is easily assembled on the shell 70.

[0063] In other embodiments not shown in the figures, the motor includes an iron material part, and the first magnetic part and the second magnetic part can cooperate with the iron material part to drive the motor to move. The first magnetic part and the second magnetic part can cooperate with the iron material part. The first magnetic part cooperates with the iron material part to drive the motor to move upward.

[0065] The cooking appliance further comprises a container detection device and a controller, both of which are arranged on the base 10. The controller controls the movement of the motor according to the detection signal of the container detection device. When the controller and the container detection device cooperate, the movement of the motor is more accurate and the degree of automation is high.

[0066] Preferably, the controller is connected to the motor 31. The container detection device is connected to the controller, and when the first container 21 is loaded into the base 10, the container detection device transmits a first container signal to the controller. The controller controls the motor 31 and the transmission member 32 to move down together to avoid the first container 21. When the second container 22 is loaded into the base 10, the container detection device transmits a second container signal to the controller, and the controller controls the motor 31 and the transmission member 32 to move up together so that the transmission member 32 is docked with the stirring structure 90, and the motor 31 drives the stirring structure 90 to rotate through the transmission member 32.

[0067] In the first embodiment, after receiving the first container signal and the second container signal, the controller can be used to prompt the user of the type of the current container, or directly control the start and stop of the motor, which can effectively prevent the user from mixing containers and prevent the motor from starting when it is not necessary, thereby avoiding wasting electricity and extending the service life of the motor.

[0068] It should be noted that the first container 21 of the first embodiment is a container without a stirring structure, similar to the container of an ordinary pressure cooker or rice cooker. The controller can be a main control chip or a single-chip microcomputer, etc. "Moving up" or "moving down" can refer to the movement state of moving up or moving down, and can also refer to the position after moving up or moving down.

[0069] In the first embodiment, the motor drives the transmission member to rotate to drive the stirring mechanism to rotate, which can be turned on according to the user's operation. For example, a stirring button is set on the operation panel of the cooking appliance, which can be a physical button or a virtual button displayed on the touch screen. When the user does not press or touch the stirring button, the motor does not start, and when the user presses or touches the stirring button, the motor starts. In this way, the cooking appliance is easy to operate, safe and convenient to operate.

[0070] In the first embodiment, the cooking utensil further comprises an operation panel, and the operation panel is connected to the controller. When the container detection device transmits a first container signal, the controller sends a first prompt signal to the operation panel, and when the container detection device transmits a second container signal, the controller sends a second prompt signal to the operation panel. When the operation panel receives an ordinary container signal, it can prompt the user that the utensil is an ordinary container, a container without a stirring structure. When the operation panel receives a stirring container signal, it can prompt the user that the utensil is a stirring container, a container with a stirring structure. The prompting methods of the first and second prompting signals include prompt lights, text displays, sounds, and the like.

[0071] Specifically, Figure 1 to Figure 1c , Figure 8 As shown, the container detection device includes a first container detection device 6 and a second container detection device. The first container detection device is arranged in the base 10 and is located below the first container 21 or the second container 22. The second container detection device is arranged at the handle 7 of the second container 22 and the corresponding position of the base 10 and the handle 7. The handle of the first container 21 does not need to be provided with a container detection device. The second container detection device includes a first connector 4 arranged on the handle 7 and a second connector 5 arranged on the base 10. The first container detection device 6, the first connector 4 or the second connector 5 are all connected to the controller.

[0072] After the first container 21 or the second container 22 is placed in the base 10, it is determined whether the first container 21 or the second container 22 is a common container or a stirring container. When the first container 21 is placed in the base 10, the bottom of the first container 21 has a flat surface or an arc surface, and the flat surface or the arc surface touches the first container detection device 6. The bottom of the first container 21 presses down the first container detection device 6 (such as Figure 1cWhen the first container 21 is placed in the base 10, the second container 22 has an avoidance structure at the bottom, which can avoid the first container detection device 6. The bottom of the second container 22 does not touch the first container detection device 6, the first container detection device 6 does not deform, and the first container detection device 6 does not send a signal. At the same time, the first connector 4 of the second container 22 is connected to the second connector 5 on the base 10, and the controller receives the signal of the first connector 4 and the second connector 5 being connected, that is, the second container signal. The operation panel will prompt the user that the second container 22 is a stirring container according to the signal of the controller.

[0073] like Figure 7 and Fig.13 As shown, the magnetic mechanism 60 also includes a first magnetic member 61 located above the motor 31 and a second magnetic member 62 located below the motor 31. When the container detection device outputs the first container signal, the motor 31 moves downward under the action of the second magnetic member 62. At this time, the second magnetic member 62 can apply a magnetic force to the motor 31 to achieve the downward movement of the motor 31. When the container detection device outputs the second container signal, the motor 31 moves upward under the action of the first magnetic member 61. At this time, the first magnetic member 61 can apply a magnetic force to the motor 31 to achieve the position of the motor 31 after moving upward.

[0074] The magnetic mechanism also includes a first magnetic member located above the motor and a second magnetic member located below the motor. When the container detection device outputs the first container signal, the motor moves downward under the action of the second magnetic member, and at this time, the second magnetic member generates a downward attraction force to achieve the downward movement of the motor. When the container detection device outputs the second container signal, the motor moves upward under the action of the first magnetic member, and at this time, the first magnetic member generates an upward magnetic attraction force to achieve the position of the motor after moving upward.

[0075] like Figure 4 , Figure 7 , Fig.10 and Fig.13 As shown, the cooking appliance further includes a housing 70, and the motor 31 is a motor installed in the housing 70. The output shaft of the motor passes through the housing 70 and is connected to the transmission member 32, and the magnetic mechanism 60 drives the housing 70 to move up or down. The setting of the housing 70 can effectively protect the motor, and also facilitates the movement of the motor connected to the fixing member 50 by the magnetic mechanism 60.

[0076] like Figure 3 and Fig. 9As shown, the base 10 includes an outer shell 11 and a heat-insulating cover 12 arranged in the outer shell 11, a fixing frame is arranged between the bottom of the heat-insulating cover 12 and the bottom wall of the outer shell 11, and a avoidance hole 121 for the transmission member 32 to pass through is arranged at the bottom of the heat-insulating cover 12. The arrangement of the avoidance hole 121 enables the heat-insulating cover 12 to avoid the transmission member 32, so that the transmission member 32 can pass through. The cooking utensil also includes a heating device 13 arranged in the heat-insulating cover 12, and a through hole 131 is arranged on the heating device 13, and the transmission member 32 is arranged at the through hole 131. The arrangement of the through hole 131 enables the heating device 13 to avoid the transmission member 32, so that the transmission member 32 can pass through. In this way, the transmission member 32 can move between the heat-insulating cover 12 and the heating device 13, so that the transmission member 32 can be connected to the stirring structure 90.

[0077] In the present application, the first container 21 has a smooth bottom. It should be noted that the "smooth bottom" means that the bottom is flat or curved, and there is no concave portion on the bottom surface for avoiding the transmission member. At the same time, the "smooth bottom" also includes a bottom with a pattern and a certain degree of roughness.

[0078] When the first container 21 is installed on the base 10, the top surface of the transmission member is flush with or lower than the surface of the heating device. When the second container is installed on the base, the top surface of the transmission member is higher than the surface of the heating device. A recess is provided at the bottom of the second container, and the stirring structure and the transmission member are connected in the recess. Figure 8 As shown, due to the provision of the recess, the stirring structure does not protrude from the bottom surface of the second container, so that the second container can be stably placed on the platform surface.

[0079] It should be noted that the heating device 13 of the first embodiment is a common heating disk. Of course, in other embodiments not shown in the figures, the heating device can be an IH coil disk, so that the bottom of the heat preservation cover is completely open and the fixing member is fixed on the IH coil disk. The heating device can also be an electric heating film.

[0080] like Figure 1 , Figure 8 and Fig.15 As shown, the outer shell 11 includes an upper shell and a base 111 , the fixing plate 51 is connected to the heat-insulating cover 12 , the support column 52 is connected to the base 111 , and the fixing member 50 is fixed between the heat-insulating cover 12 and the base 111 .

[0081] like Figure 3 , Figure 4 , Fig. 9 , Fig.10 and Fig.17As shown, the motor 31 is connected to the transmission member 32 through the connecting pin 33. In this way, when the motor 31 moves up and down, the transmission member 32 can move up and down together with the motor 31 through the connecting pin 33. The connection method is simple and the cost is low. The cooking utensil also includes a baffle 72 connected to the shell 70 and a bottom plate 73 located below the fixing member 50. The baffle 72 can isolate the heat generated by the heating device 13, thereby protecting the motor. The bottom plate 73 is connected to the shell 11, and the second magnetic member 62 is installed on the bottom plate 73 for easy fixing and installation. The first magnetic member 61 is installed on the fixing plate 51 for easy fixing and installation.

[0082] Specifically, Figure 1 , Figures 5 to 7 As shown, a step surface 321 is provided on the transmission member 32. When the first container 21 is loaded into the heat preservation cover 12, the first container detection device 6 is triggered, and the first container detection device 6 transmits the first container signal to the controller. The controller determines that the first container 21 is an ordinary container, and the controller controls the second magnetic member 62 so that the second magnetic member 62 attracts the fourth magnetic member on the rack 82 to move downward under the action of magnetic force, so that the motor 31 and the transmission member 32 move downward together, and the motor 31 and the transmission member 32 can avoid the first container 21. At this time, the distance L1 between the lower surface of the fixed plate 51 and the upper surface of the baffle 72 is greater than the distance L2 between the upper surface of the fixed plate 51 and the step surface 321 of the transmission member 32. After the cooking of the cooking utensils is finished, the controller controls the second magnetic member 62 to turn off the magnetic force and controls the first magnetic member 61 to turn on, so that the first magnetic member 61 attracts the third magnetic member on the rack 82 to move upward under the action of magnetic force, and at this time, the motor 31 and the transmission member 32 return to the upward position. Of course, after cooking is finished, the motor 31 and the transmission member 32 may not return to the upward position but remain in the downward position, and be adjusted according to the type of container to be put in next time, such as keeping the position unchanged or moving upward.

[0083] Specifically, Figure 8 , Figures 11 to 13 As shown, when the first container 21 or the second container 22 is not placed in the base 10, the transmission member 32 at the bottom of the base 10 protrudes from the upper surface of the heating device 13. When the second container 22 is placed in the base 10, the first container detection device 6 is not triggered, and at the same time, the first connector 4 or the second connector 5 transmits the second container signal to the controller, and the controller determines that the second container 22 is a stirring container, and the transmission member 32 is connected to the stirring structure 90 in the second container 22. At this time, the distance L2 from the upper surface of the fixed plate 51 to the step surface 321 of the transmission member 32 is greater than the distance L1 between the lower surface of the fixed plate 51 and the upper surface of the baffle 72.

[0084] When the cooking appliance is a pressure cooker, the cooking appliance further comprises a pot cover, a pressure limiting valve and a sealing ring arranged on the pot cover, and an anti-detachment mechanism is arranged between the pot cover and at least one of the first container 21, the second container 22 and the heat-insulating cover 12. The anti-detachment mechanism refers to a mechanism that prevents the pot cover from detaching from the pot body when pressure is applied in the first container or the second container, and can be a pot tooth, a cover tooth or a caliper structure in the prior art.

[0085] In the first embodiment, the cooking utensil is an electric pressure cooker or an electric rice cooker. Of course, in other embodiments not shown, the cooking utensil can also be an electric rice cooker, a low-pressure rice cooker, a soybean milk machine, a food processor, an electric stew pot, a cooking machine, a multi-function pot and other products.

[0086] like Fig.18 As shown, in the second embodiment of the cooking utensil provided in the present application, the difference from the first embodiment lies in the structure of the base. In the second embodiment, there is no shell and heat preservation cover. In the second embodiment, the base includes a base 6a, and the first container or the second container can be arranged above the base 6a. A receiving cavity is arranged in the base 6a, and the driving mechanism and the connecting member are arranged in the receiving cavity.

[0087] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0088] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0089] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
