Description

Technical Field

[0001] The present invention relates to the technical field of small household appliances, and more particularly, to a cooking appliance. Background Art

[0002] In the related art, a cooking appliance includes a base body and a container disposed on the base body. The base body is used to support or accommodate the container, and the container is used to accommodate the food ingredients to be processed. The base body is generally a pot body or a base, and the container can be an inner pot or a cup body.

[0003] In order to facilitate the processing of food ingredients, the container of some cooking appliances is provided as a stirring container, and the stirring container is provided with a stirring structure, such as a cooking machine or a bread machine. The above-mentioned stirring structure includes a stirring blade and an upper coupler. A motor and a lower coupler are disposed in the base body, and the output shaft of the motor drives the stirring blade through the cooperation of the upper coupler and the lower coupler. When the stirring blade rotates in the container, it can stir the food ingredients.

[0004] In the above structure, when cooking food ingredients that do not require stirring, such as cooking rice or making soup, the setting of the stirring structure will occupy space and affect cooking operations. At this time, it can be considered to add an ordinary container similar to the inner pot of an electric rice cooker. However, since there is a lower coupler disposed in the base body, it will interfere with the above-mentioned ordinary container, resulting in the inability to use the ordinary container. Summary of the Invention

[0005] The present invention aims to provide a cooking appliance to solve the problem in the related art that the lower coupler interferes with the ordinary container, resulting in the inability to use the ordinary container.

[0006] To achieve the above object, the present invention provides a cooking appliance, including: a base body; a first container and a second container that can be installed on the base body, the second container having a stirring structure; a driving mechanism disposed on the base body, the driving mechanism including a motor and a transmission mechanism that is drivingly coupled with the motor, the transmission mechanism including a transmission member that can be docked with the stirring structure; wherein the transmission member is movably disposed on the base body and has an avoidance position for avoiding the first container or a docking position for docking with the stirring structure; and a heating device disposed on the base body.

[0007] Applying the technical solution of the present invention, the transmission member is movably arranged on the base body and has an avoidance position for avoiding the first container or a docking position for docking with the stirring structure. When the first container is installed on the base body and the transmission member is moved to the avoidance position, the transmission member can avoid the first container and there will be no interference between the transmission member and the first container. When the second container is installed on the base body, the transmission member moves to dock with the stirring structure, and the motor can drive the transmission member to rotate to drive the stirring structure to rotate. Therefore, the cooking appliance of the present application can use both the first container without a stirring structure and the second container with a stirring structure, enabling the cooking appliance to have multiple cooking functions. Therefore, the technical solution of the present application effectively solves the problem in the related art that the lower coupler interferes with ordinary containers, resulting in the inability to use ordinary containers.

[0008] Further, the transmission member is movably arranged on the base body along a predetermined straight line direction. The above-mentioned movement along the predetermined straight line direction makes the setting of the transmission member easier and the structure simpler.

[0009] Further, the cooking appliance further includes an elastic reset member arranged on the base body, and the elastic reset member is arranged below or on one side of the transmission member. When the first container is installed on the base body, the bottom of the first container presses down or presses on the side of the transmission member, and the elastic reset member is compressed under pressure, and the transmission member moves to the avoidance position. In this way, under the action of the first container and the elastic reset member, the transmission member can achieve movement, that is, the lifting or translation of the transmission member is realized.

[0010] Further, the cooking appliance further includes a fixing member connected to the base body, the transmission member is passed through the fixing member, and the elastic reset member is located between the transmission member and the fixing member. In this way, when the motor drives the transmission member to rotate, the fixing member can support the transmission member.

[0011] Further, the heating device is located below the first container or the second container, and an avoidance hole is provided on the heating device. When the transmission member is in the docking position, it passes through the avoidance hole. The above-mentioned avoidance hole can avoid the transmission member.

[0012] Further, the transmission mechanism further includes a linkage mechanism arranged between the motor and the transmission member. The motor has an output shaft, and the output shaft drives the transmission member to rotate through the linkage mechanism. The arrangement of the above-mentioned linkage mechanism enables the power of the motor to be transmitted to the transmission member, and the layout of the linkage mechanism enables the motor to be arranged more flexibly without directly driving the transmission member.

[0013] Further, the linkage mechanism includes: a driving wheel arranged on the output shaft; a driven wheel; the above-mentioned motor can drive the driving wheel to rotate together. The transmission member is movably passed through the driven wheel; a belt or a chain is wound around the driving wheel and the driven wheel. With the above-mentioned structure, under the action of the belt or the chain, the driving wheel and the driven wheel can achieve synchronous rotation.

[0014] Further, the cooking appliance further includes a support member and a fixed retaining ring respectively located on the upper and lower sides of the driven wheel, and both the support member and the fixed retaining ring are connected to the base body. The above-mentioned driven wheel is restricted between the support member and the fixed retaining ring. Furthermore, the support member and the fixed retaining ring can restrict the movement of the driven wheel in the axial direction thereof, preventing the driven wheel from shifting during rotation.

[0015] Further, the cooking appliance further includes a fixing member connected to the base body and a stop member provided on the transmission member. The transmission member is passed through the fixing member, and the stop member is in a stop fit with the fixing member. In the case where the transmission member moves upward, the stop member is blocked below the fixing member, preventing the transmission member from continuing to move upward.

[0016] Further, the heating device is located below the first container or the second container. The first container has a smooth bottom surface. When the first container is installed on the base body, 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 body, the top surface of the transmission member is higher than the surface of the heating device; a concave portion is provided at the bottom of the second container, and the stirring structure is docked with the transmission member in the concave portion; the cooking appliance is an electric pressure cooker or a rice cooker; the base body includes an outer pot and a heat preservation cover provided inside the outer pot. When the cooking appliance is a pressure cooker, the cooking appliance further includes a pot lid and a pressure limiting valve and a sealing ring provided on the pot lid. At least one of the first container, the second container, and the heat preservation cover is provided with an anti-disengagement mechanism between the pot lid. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0032] 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.

[0033] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0034] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. 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.

[0035] like Figures 1 to 4 , Figure 6 and Figure 8 As shown, the cooking utensil of the first embodiment includes: a base 10, a first container 21, a second container 22, a driving mechanism and a heating device 60. The first container 21 and the second container 22 can be installed on the base 10, and the second container 22 has a stirring structure 90. The driving mechanism is arranged on the base 10, and the driving mechanism includes a motor 31 and a transmission mechanism 32 driven by the motor 31. The transmission mechanism 32 includes a transmission member 321, and the transmission member 321 can be docked with the stirring structure 90. Among them, the transmission member 321 can be movably arranged on the base 10 and has an avoidance position for avoiding the first container 21 or a docking position for docking with the stirring structure 90. The heating device 60 is arranged on the base 10.

[0036] Applying the technical solution of Embodiment 1, the transmission member 321 is movably arranged on the base body 10 and has an avoidance position for avoiding the first container 21 or a docking position for docking with the stirring structure 90. When the first container is installed on the base body, the transmission member moves to the avoidance position, and the transmission member can avoid the first container. The transmission member will not interfere with the first container. When the second container is installed on the base body, the transmission member moves to dock with the stirring structure, and the motor can drive the transmission member to rotate to drive the stirring structure to rotate. Therefore, the cooking appliance of the present application can use both the first container without a stirring structure and the second container with a stirring structure, enabling the cooking appliance to have multiple cooking functions, so that the cooking appliance includes multiple cooking modes, bringing users a choice of multiple different cooking modes. Therefore, the technical solution of Embodiment 1 effectively solves the problem in the related art that the lower coupler interferes with ordinary containers, resulting in the inability to use ordinary containers.

[0037] It should be noted that: the base body 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 321 can move to make room, such as moving downward (when the transmission member is arranged below the container) or moving sideways (when the transmission member is arranged on the side of the container). In this way, when the first container 21 is placed in the base body, it will no longer interfere with the transmission member. The above-mentioned "docking" means that the transmission member and the stirring structure can be inserted and matched and can rotate synchronously.

[0038] In an embodiment not shown in other figures, the transmission member is arranged in the base body in a swinging manner or a flipping manner and has an avoidance position for avoiding the first container or a docking position for docking with the stirring structure.

[0039] In the present application, the motor drives the transmission member to rotate to drive the stirring structure to rotate, which can be turned on according to the user's operation. For example, a stirring key can be 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 key, the motor does not start. When the user presses or touches the stirring key, the motor starts.

[0040] As Figure 1 、 Figure 4 and Figure 5 shown, in Embodiment 1, the transmission member 321 is movably arranged on the base body 10 along a predetermined straight line direction. The above-mentioned movement along the predetermined straight line direction is convenient for guiding and easy to implement.

[0041] As Figure 1 、 Figure 4 and Figure 5As shown, in the first embodiment, the cooking appliance further includes an elastic reset member 40 disposed on the base body 10, and the elastic reset member 40 is disposed below the transmission member 321. When the first container 21 is mounted on the base body 10, the bottom of the first container 21 presses down the transmission member 321, the elastic reset member 40 is compressed under pressure, and the transmission member 321 moves to the avoidance position. When the first container 21 is loaded into the base body 10, the bottom of the first container 21 presses down the transmission member 321, the elastic reset member 40 is compressed under pressure, and the transmission member 321 moves downward. When the first container 21 is removed from the base body 10, the bottom of the first container 21 no longer presses against the transmission member 321, the elastic reset member 40 resets, and the elastic reset member 40 drives the transmission member 321 upward, causing the transmission member 321 to move upward. In this way, under the action of the first container 21 and the elastic reset member 40, the upward or downward movement of the transmission member 321 is achieved, that is, the lifting or lowering of the transmission member 321 is achieved. The elastic reset member 40 has a simple structure and is easy to implement.

[0042] In the first embodiment, as Figure 6 and Figure 7 shown, the stirring structure is disposed at the bottom of the second container, and the transmission member is located at the bottom of the base body. In an embodiment not shown in other figures, the stirring structure may also be disposed on the side of the second container. Correspondingly, the transmission member is located on the side of the base body. At this time, the elastic reset member is disposed on one side of the transmission member. When the first container is mounted on the base body, the side of the first container laterally presses the transmission member.

[0043] As Figure 1 、 Figure 4 and Figure 5 shown, in the first embodiment, the cooking appliance further includes a fixing member 50 connected to the base body 10. The transmission member 321 is disposed through the fixing member 50, and the elastic reset member 40 is located between the transmission member 321 and the fixing member 50. The transmission member 321 includes a transmission cylinder portion and a shaft portion connected to the transmission cylinder portion, and the shaft portion is disposed through the fixing member 50. The elastic reset member 40 is located between the transmission cylinder portion and the fixing member 50. In this way, when the motor drives the transmission member 321 to rotate, the fixing member 50 can support the transmission member 321. In addition, the arrangement of the fixing member 50 facilitates the arrangement of the elastic reset member 40. When the elastic reset member 40 is compressed under pressure, the transmission member 321 moves downward. At this time, the bottom of the first container 21 abuts against the top of the fixing member. In this way, it is beneficial for the transmission member 321 to avoid the first container 21.

[0044] As Figure 4 、 Figure 8 and Figure 10As shown, in the first embodiment, the fixing member 50 includes a cylindrical body 51 and a flange 52 provided on the cylindrical body 51, and the flange 52 is connected to the base body 10. A ring groove 511 is formed on the bottom wall of the cylindrical body 51, and a stepped surface 3211 is formed on the side wall of the transmission member 321. One end of the elastic reset member 40 abuts against the stepped surface 3211, and the other end of the elastic reset member 40 abuts against the ring groove 511. In this way, the elastic reset member 40 can apply an elastic force to the transmission member 321 to facilitate the movement of the transmission member 321 along its axial direction. The elastic reset member 40 in the first embodiment is preferably a spring. In an embodiment not shown in other figures, the fixing member may also include a fixing bracket, which includes a fixing plate and a support column provided below the fixing plate. The transmission member is passed through the fixing plate, and the elastic reset member is located between the fixing plate and the transmission member. The motor is located below or on one side of the fixing plate.

[0045] As Figure 1 and Figure 6 shown, in the first embodiment, the cooking appliance further includes a heating device 60 provided in the base body 10. The heating device 60 is located below the first container 21 or the second container 22. An avoidance hole 61 is provided on the heating device 60. When the transmission member 321 is in the docking position, it passes through the avoidance hole 61. In this way, the avoidance hole 61 can avoid the transmission member 321. At the same time, the avoidance hole 61 provides an installation space for the fixing member 50 below the first container 21 or the second container 22, facilitating the installation of the fixing member 50.

[0046] As Figure 1 and Figure 6 shown, in the first embodiment, the transmission mechanism 32 further includes a linkage mechanism 33 provided between the motor 31 and the transmission member 321. The motor 31 has an output shaft 311, and the output shaft 311 drives the transmission member 321 to rotate through the linkage mechanism 33.. The setting of the linkage mechanism 33 enables the power of the motor 31 to be transmitted to the transmission member 321, and the arrangement of the linkage mechanism 33 enables the motor 31 to be arranged more flexibly without directly driving the transmission member 321.

[0047] As Figure 1 and Figure 6 shown, the linkage mechanism 33 includes a driving wheel 331, a driven wheel 332, and a belt 333 or a chain. The driving wheel 331 is provided on the output shaft 311. In this way, the motor 31 can drive the driving wheel 331 to rotate together. The transmission member 321 is movably passed through the driven wheel 332. When the transmission member 321 cooperates with the driven wheel 332, the transmission member 321 and the driven wheel 332 are in cooperation through a transmission plane. At this time, the transmission member 321 and the driven wheel 332 can rotate synchronously. The belt 333 or the chain is wound around the driving wheel 331 and the driven wheel 332. In this way, under the action of the belt 333 or the chain, the driving wheel 331 and the driven wheel 332 can be synchronized to rotate.

[0048] In an embodiment not shown in other figures, the linkage mechanism includes a gear mechanism. For example, the gear mechanism includes a driving gear and a first driven gear drivingly connected to the driving gear. The output shaft of the motor is connected to the driving gear, and the transmission member is connected to the first driven gear. The gear mechanism may further include a second driven gear connected between the driving gear and the first driven gear. When the output shaft of the motor rotates, the output shaft can drive the driving gear to rotate, and the driving gear drives the first driven gear to rotate, thereby driving the transmission member to rotate, or the driving gear drives the second driven gear to rotate, and the second driven gear then drives the first driven gear to rotate, ultimately driving the transmission member to rotate.

[0049] Such as Figure 6 , Figure 7 and Figure 9 As shown in

[0050] In the first embodiment, the stirring structure 90 includes stirring blades 91, a tool holder assembly 92, a nut 93, and a connector 94. The tool holder assembly 92 is fixed to the second container 22 by the nut 93. The tool holder assembly 92 is connected to the connector 94, and the outer side of the connector 94 is inserted into the transmission member 321. When the transmission member 321 rotates, the transmission member 321 drives the stirring blades 91 to rotate synchronously through the tool holder assembly 92. Figure 1 As Figure 4 , Figure 6 , Figure 8 and Figure 11 As shown in

[0051] In the first embodiment, as Figure 4 , Figure 8 and Figure 11As shown, the base body 10 includes an outer pot and a heat preservation cover 12 arranged inside the outer pot, and the fixing member 50 is connected to the heat preservation cover 12. The cooking appliance further includes a support plate 73, on which legs are arranged, and the support plate 73 is fixed to the heat preservation cover 12 through the legs. The support member 71 is connected to the fixing member 50, so that the support member 71 can be fixed to the heat preservation cover 12 through the fixing member 50. A fixed retaining ring 72 is connected to the support plate 73. The fixed retaining ring 72 is fixed to the support plate 73 through fasteners, so that the support plate 73 can fix the fixed retaining ring 72. The cooking appliance further includes a fixed bracket 76, and the heat preservation cover 12 is fixed to the outer pot through the fixed bracket 76.

[0052] As Figure 4 and Figure 8 As shown, in the first embodiment, the cooking appliance further includes a fixing member 50 connected to the base body 10 and a stopper 74 arranged on the transmission member 321. The transmission member 321 is arranged through the fixing member 50, and the stopper 74 is in a stopper fit with the fixing member 50. When the transmission member 321 moves downward, the stopper 74 is blocked above the driven wheel 332 to prevent the transmission member 321 from continuing to move downward. When the transmission member 321 moves upward, the stopper 74 is blocked below the fixing member 50 to prevent the transmission member 321 from continuing to move upward. In this way, the stopper 74 can limit the moving range of the transmission member 321 along its axial direction. The stopper in the first embodiment is preferably an E-shaped stopper commonly used in the art. Of course, there are many structures of the stopper, and any structure that can achieve the function of limiting the moving range of the transmission member can be used. The cooking appliance further includes a motor fixing plate 75, the motor fixing plate 75 is connected to the base body 10, and the motor 31 is fixed on the motor fixing plate 75.

[0053] As Figure 1 、 Figure 6 and Figure 11 As shown, in the first embodiment, the motor 31 is a motor, the base body 10 includes an outer pot and a heat preservation cover 12 arranged inside the outer pot, the heating device 60 is located above the bottom wall of the heat preservation cover 12, and the fixing member 50 is connected to the heat preservation cover 12. In this way, the fixing member 50 is arranged on the heat preservation cover 12, which is convenient for stable fixing. The cooking appliance further includes a cover body that can be opened and closed to cover the base body 10.

[0054] It should be noted that the heating device 60 in the first embodiment is a common electric heating plate. Of course, in the embodiments not shown in other figures, the heating device can be an IH coil disk. At this time, the bottom of the heat preservation cover can be completely open, and the fixing member can also be fixed on the IH coil disk. The heating device can also be an electric heating film.

[0055] As Figure 1 and Figure 6As shown, when the first container 21 or the second container 22 is placed in the base body 10, the bottom of the first container 21 or the second container 22 contacts the heating device 60. The base body 10 includes an outer pot and a heat preservation cover 12 disposed inside the outer pot. Both the first container 21 and the second container 22 are placed inside the heat preservation cover 12. The heating device 60 and the fixing member 50 are located inside the heat preservation cover 12. Among them, the flange 52 of the fixing member 50 is connected to the heat preservation cover 12 through a fastener to fix the fixing member 50.

[0056] In the present application, a "smooth bottom" means that the bottom is flat or arc-shaped, and no concave portion for avoiding the transmission member is provided on the bottom surface. At the same time, a "smooth bottom" also includes a bottom provided with patterns and having a certain roughness.

[0057] In the first embodiment, the first container 21 has a smooth bottom. When the first container is installed in the base body, 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 in the base body, the top surface of the transmission member is higher than the surface of the heating device; a concave portion is provided at the bottom of the second container, and the stirring structure is docked with the transmission member in the concave portion. As Figure 7 shown, due to the provision of the concave portion, 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. The base body 10 includes an outer pot and a heat preservation cover 12 disposed inside the outer pot. When the cooking appliance is a pressure cooker, the cooking appliance further includes a pot lid and a pressure limiting valve and a sealing ring provided on the pot lid. An anti-disengagement mechanism is provided between at least one of the first container 21, the second container 22 and the heat preservation cover and the pot lid. The anti-disengagement mechanism refers to a mechanism for preventing the pot lid from disengaging from the pot body when pressure is applied inside the first container or the second container, and can be structures such as pot teeth, lid teeth or calipers in the prior art.

[0058] In the first embodiment, the cooking appliance is an electric pressure cooker or a rice cooker. Of course, in other embodiments not shown, the cooking appliance can also be products such as a rice cooker, a low-pressure rice cooker, a soybean milk machine, a cooking machine, an electric stew pot, a stir-fry machine, a multi-functional pot, etc.

[0059] As Figure 1 and Figure 6As shown, in the first embodiment, the cooking appliance further includes a controller and a transmission detection device disposed within the base body 10. The transmission detection device includes a trigger member disposed on the transmission member 321 and a sensing member disposed within the base body 10, and the sensing member is connected to the controller. When the first container 21 is loaded into the base body 10, the transmission member 321 moves downward, the trigger member triggers the sensing member, and the sensing member sends a stop signal to the controller to cause the motor 31 to be in a stopped state. When the second container 22 is loaded into the base body 10, the transmission member 321 moves upward, the trigger member fails to trigger the sensing member, and the sensing member sends an enabling signal to the controller to cause the motor 31 to be in an enabled state, and the motor 31 can drive the stirring structure 90 to rotate through the drive mechanism. The above-mentioned controller and transmission detection device can control the start and stop of the motor, avoid the motor from starting when it does not need to start, and thus extend the service life of the motor. It should be noted that the controller will only receive the signal from the transmission detection device when there is a first container or a second container within the base body 10. The specific method for determining whether there is a first container or a second container within the base body is as follows:

[0060] Both the first container and the second container are provided with handles, and a first connector is provided on the handle, and a second connector is provided on the base body. The second connector is connected to the controller. When the first connector is connected to the second connector, the controller receives

[0061] a signal that the first container or the second container has been placed in the outer pot. At this time, there is a first container or a second container in the outer pot. When the first connector is disconnected from the second connector, the controller receives a signal that the first container or the second container has been removed from the base body. At this time, there is no first container or second container in the outer pot.

[0062] As another implementation manner, the cooking appliance further includes a container detection device disposed within the base body, and the container detection device is connected to the controller. When the first container is loaded into the base body, the container detection device transmits a first container signal to the controller. When

[0063] the second container is loaded into the base body, the container detection device transmits a second container signal to the controller. In this way, after receiving the first container signal and the second container signal, the controller can be used to prompt the user of the current type of container, or directly control the motor to stop working and start working.

[0064] In the first embodiment, the cooking appliance further includes an operation panel which 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. 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 a normal container signal, it can prompt the user that this appliance is a normal container, i.e., a container without a stirring structure. When the operation panel receives a stirring container signal, it can prompt the user that this appliance is a stirring container, i.e., a container with a stirring structure. The prompting methods of the first and second prompt signals include ways such as prompt lights, text displays, sounds, etc.

[0065] Specifically, the container detection device is connected to the controller. After the first container or the second container is placed into the base, it is determined whether the first container or the second container is a normal container or a stirring container. Suppose the second container is placed in the base. The bottom of the second container has an avoidance structure which can avoid the container detection device, and the bottom of the second container does not touch the container detection device. At this time, the container detection device does not deform, and the cooking appliance is in the default state, that is, the container detection device transmits a second container signal, and the operation panel will automatically prompt the user that the second container is a stirring container according to the signal of the controller. Suppose the first container is placed in the base. The bottom of the first container has a flat surface or a curved surface, and this bottom touches the container detection device. The bottom of the first container presses down the container detection device, and the container detection device deforms. At this time, the container detection device transmits a first container signal to the controller, and the operation panel will prompt the user that the first container is a normal container according to the signal of the controller.

[0066] It should be noted that the above-mentioned controller can be a main control chip or a single-chip microcomputer, etc. The container detection device is preferably a pressure sensor. When the trigger is preferably a magnetic attracting part, the sensing part is preferably a reed switch, or when the trigger is preferably a pressing block, the sensing part is preferably a microswitch.

[0067] In the second embodiment according to the present application, the difference from the first embodiment is that the upward or downward movement of the transmission part is realized through a magnetic mechanism. Specifically, the cooking appliance includes a magnetic mechanism which includes a first magnetic part arranged in the base and a second magnetic part arranged on the transmission part. The first magnetic part and the second magnetic part repel each other. When the second container is loaded into the base, the transmission part is kept in the upward movement position under the action of the repulsive force between the first magnetic part and the second magnetic part. In this way, it is convenient for the transmission part to be directly docked with the stirring structure in the second container. When the first container is loaded into the base, the bottom of the first container presses down the transmission part to overcome the repulsive force, and the transmission part moves downward. The above-mentioned transmission part can avoid the first container, so that there is no interference between the bottom of the first container and the transmission part, which is convenient for placing the first container.

[0068] In the third embodiment according to the present application, the difference from the first embodiment is that the motor directly moves up and down to drive the transmission member to move up and down. Specifically, the motor and the transmission member are movably arranged on the fixing member. The cooking appliance further includes a magnetic mechanism for driving the motor and the transmission member to move up or down. In this way, under the action of the magnetic mechanism, the motor can directly drive the transmission member to move up or down, facilitating the transmission member to avoid or cooperate with the stirring structure.

[0069] In the third embodiment, the magnetic mechanism further includes a first magnetic member located above the motor and a second magnetic member located below the motor. When the container detection device outputs a first container signal, the motor moves down under the action of the second magnetic member. At this time, the second magnetic member can apply a magnetic force to the motor to realize the downward movement of the motor. When the container detection device outputs a second container signal, the motor moves up under the action of the first magnetic member. At this time, the first magnetic member can apply a magnetic force to the motor to realize the position of the motor after moving upward.

[0070] As Figure 12 shown, in the fourth embodiment of the cooking appliance provided in the present application, the difference from the first embodiment lies in the structure of the base body. In the fourth embodiment, there is no outer shell and heat preservation cover. In the fourth embodiment, the base body includes a base 6, and the first container or the second container can be arranged above the base 6. A receiving cavity is arranged in the base 6, and the driving mechanism and the connecting member are arranged in the receiving cavity.

[0071] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0072] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations for the spatial relative descriptions used herein will be made accordingly.

[0073] In addition, it should be noted that the use of terms such as "first", "second" etc. to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present invention.

[0074] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
