TECHNICAL FIELD

[0001] The present application relates to the technical field of small household appliances, in particular to a cooking appliance. BACKGROUND

[0002] In the related art, a cooking appliance includes a base and a container arranged on the base, the base is used for supporting or containing the container, and the container is used for containing food materials to be processed. The base is generally a pot body or a base, and the container can be an inner container or a cup body.

[0003] In order to facilitate the processing of food materials, the container of some cooking appliances is arranged as a stirring container, which is provided with a stirring structure, such as a frying machine or a bread machine. The stirring structure includes stirring blades and an upper coupling device. A motor and a lower coupling device are arranged in the base, and the output shaft of the motor drives the stirring blades through the cooperation of the upper coupling device and the lower coupling device. The stirring blades rotate in the container to stir the food materials.

[0004] In the above structure, when cooking food materials that do not require stirring, such as cooking rice or making soup, the arrangement of the stirring structure will occupy space and affect the cooking operation. At this time, a common container similar to the inner container of a rice cooker can be considered. However, since the lower coupling device is arranged in the base, it will interfere with the common container, resulting in the inability to use the common container. SUMMARY

[0005] The present application aims to provide a cooking appliance to solve the problem that the lower coupling device in the related art will interfere with the common container, resulting in the inability to use the common container.

As will be realized, the application is capable of modifications in various obvious aspects, all without departing from the scope of the inventive subject matter. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature, and not as restrictive.

[0037] As Figures 1 to 4 , Figures 7 to 9As shown, the cooking appliance of the first embodiment comprises a base 10, a first container 21, a second container 22, a pot cover 80, a first driving mechanism 30 and a heating device 60. The first container 21 and the second container 22 can be loaded on the base 10, and the second container 22 has a stirring structure 90. The pot cover 80 is arranged on the first container 21 or the second container 22. The first driving mechanism 30 is arranged on the base 10, and the first driving mechanism 30 comprises a power source 31 and a transmission member 32 driven by the power source 31. The heating device 60 has an avoiding hole 62 for avoiding the transmission member 32, and the heating device 60 is movably arranged on the base 10 and has a first position and a second position. When the heating device 60 is in the first position, the transmission member 32 does not protrude out of the avoiding hole 62. When the heating device 60 is in the second position, the transmission member 32 protrudes out of the avoiding hole 62 and can be in butt joint with the stirring structure 90.

[0038] By applying the technical solution of the first embodiment, the heating device 60 is movably arranged on the base 10 and has a first position and a second position. When the heating device 60 is in the first position, the transmission member 32 does not protrude out of the avoiding hole 62, and the first container 21 without the stirring structure 90 can be loaded on the base 10. At this time, the transmission member 32 can avoid the first container 21, and the transmission member 32 will not interfere with the first container 21. When the heating device 60 is in the second position, the second container 22 can be loaded on the base 10, the transmission member 32 protrudes out of the avoiding hole 62 and can be in butt joint with the stirring structure 90, and the power source 31 can drive the transmission member 32 to rotate to drive the stirring structure 90 to rotate. Therefore, the cooking appliance of the first embodiment can use both the first container 21 without the stirring structure 90 and the second container 22 with the stirring structure 90, and can have multiple cooking functions. In this way, the problem that the lower coupling will interfere with the ordinary container in the related art, resulting in the failure to use the ordinary container, is effectively solved.

[0039] It should be noted that the base is generally a pot body or a base, and the container can be an inner container or a cup body. The above-mentioned "avoiding" means that the heating device 60 can be moved to drive the container to move, such as up and down. In this way, the first container 21 will not interfere with the transmission member when it is placed in the base. The above-mentioned "butt joint" means that the transmission member and the stirring structure can be in plug-in joint and can rotate synchronously.

[0040] For example, Figure 7 and Figure 11As shown in the first embodiment, the second container 22 is provided with a recess 221. The stirring structure 90 is located in the recess 221. When the heating device 60 is in the second position, a part of the transmission member 32 extends into the recess 221 and cooperates with the stirring structure 90. The recess 221 forms a cooperating space on the bottom surface of the second container 22, so that when a part of the transmission member 32 cooperates with the stirring structure 90, the transmission member 32 does not interfere with the bottom surface of the second container 22. At the same time, the stirring structure 90 is arranged in the recess 221, so that when the second container 22 is placed on the operation table or the like, the stirring structure 90 does not affect the stable placement of the second container 22. In other embodiments not shown in the drawings, the stirring structure can also be arranged on the side of the second container, and correspondingly, the transmission member is arranged on the side of the base body.

[0041] As shown in the first embodiment, Figure 2 , Figure 4 , Figure 7 and Figure 9 , the cooking utensil further comprises an elastic mechanism 40 arranged between the heating device 60 and the base body 10. When the first container 21 is mounted on the base body 10, the force exerted by the heating device 60 on the elastic mechanism 40 is weakened, and the elastic mechanism 40 rebounds so that the heating device 60 is in the first position. The elastic mechanism 40 is supported between the heating device 60 and the base body 10, so that the heating device 60 can move up and down.

[0042] As shown in the first embodiment, Figure 2 , Figure 4 , Figure 7 and Figure 9 , the elastic mechanism 40 comprises a support column 41 arranged on the heating device 60 and an elastic member 42 sleeved on the support column 41. The first end of the elastic member 42 cooperates with the heating device 60, and the second end of the elastic member 42 cooperates with the base body 10. The support column 41 can guide the elastic member 42. The elastic member 42 is simple in structure, easy to assemble, and low in cost. The elastic member of the present embodiment is preferably a spring.

[0043] In an embodiment not shown in other figures, the cooking utensil further comprises a second driving mechanism arranged between the heating device and the base, the second driving mechanism being capable of driving the heating device to move. Under the action of the second driving mechanism, the heating device can move up and down. Alternatively, the heating device can also move up and down by manually pressing the heating device. The second driving mechanism comprises a controller, a button connected to the controller, and an executing mechanism connected to the controller, the executing mechanism being capable of driving the heating device to move, and the controller controls the executing mechanism to control the heating device to move according to the signal of the button. In this way, by triggering the button to make the button send a signal, under the control of the controller, the executing mechanism controls the heating device to move up and down. The executing mechanism can be a gear and a rack cooperating with each other, the rack is fixed on the heating device, and the gear is arranged on the output shaft of the motor. The gear and the rack are engaged, and a guide mechanism of the rack also needs to be arranged. The button can be a physical button or a touch button, and the user selects the heating device to be in the first position or the second position through the button to facilitate the first container or the second container to be put in. The button control operation is convenient, and the user experience is improved.

[0044] As shown in Figure 9 and Figure 13 , in Embodiment One, the base 10 comprises a support portion below the heating device 60, and the support portion is provided with a through hole 121 through which the support column 41 passes. In the process of moving the heating device 60 from the first position to the second position, the through hole 121 is arranged so that the support portion can avoid the support column 41, thereby facilitating the heating device 60 to move up and down. In Embodiment One, the base 10 comprises an outer pot and a heat preservation cover, and the support portion is the bottom wall of the heat preservation cover. In Figure 14 Embodiment Two shown in the figure, the base comprises a base, and the support portion is a support plate arranged inside the base.

[0045] As shown in Figure 6 , Figure 12 and Figure 13 , in Embodiment One, the base 10 comprises an outer pot 11 and a heat preservation cover 12 arranged in the outer pot 11, the heating device 60 is located above the bottom wall of the heat preservation cover 12, and the fixing member 50 is connected with the heat preservation cover 12. The base 10 further comprises a middle plate arranged on the heat preservation cover 12, the handle seat 13 is a part of the middle plate, and the support portion is a part of the bottom of the heat preservation cover 12.

[0046] As shown in Figure 6 and Figure 11As shown, in Embodiment 1, the cooking appliance also includes a lid 80 placed on the base 10. When the first container 21 is mounted on the base 10, since the height H1 of the first container 21 is lower than the height H2 of the second container 22, the lid 80 does not contact the first container 21 when closed, and the lid 80 does not exert force on the first container 21. Therefore, the heating device 60 is not subjected to force from the lid 80, and the heating device 60 can be in the first position. When the second container 22 is mounted on the base 10, since the height H2 of the second container 22 is higher than the height H1 of the first container 21, the lid 80 contacts the second container 22 when closed, and the lid 80 exerts force on the second container 22, causing the second container 22 to press down on the heating device 60. When the lid 80 is on the base 10, the heating device 60 is in the second position. Thus, by using the lid 80 to press down on the second container 22, the heating device 60 can be pressed down, thereby placing the heating device 60 in the second position.

[0047] Of course, in embodiments not shown in the figures, the height H1 of the first container is equal to the height H2 of the second container. The first container is mounted on the base, the lid does not contact the first container, and the heating device is held in the first position by the support of an elastic mechanism or transmission component. The second container is mounted on the base, the lid does not contact the second container, and the second container presses down on the elastic mechanism to move the heating device downwards, placing the heating device in the second position.

[0048] like Figure 4 and Figure 9 As shown, the heating device 60 in Embodiment 1 is an electric heating plate. Electric heating plates are convenient to use, have low cost, and facilitate heating of both the first and second containers. In other embodiments not shown in the figures, the heating device is an IH coil, which provides better heating. The heating device can also be an electric heating film.

[0049] like Figures 5 to 7 As shown, in Embodiment 1, the cooking appliance also includes a handle base 13 connected to the base 10, and a handle 23 is provided on the first container 21. When the first container 21 is mounted on the base 10, an elastic mechanism is not required below the first container 21, and the handle base 13 can support the handle 23, with the heating device 60 in the first position. Thus, the handle 23 facilitates the user in lifting and placing the first container 21, and also provides support. The handle 23 has a simple structure and is easy to implement.

[0050] like Figures 7 to 9As shown in the embodiment one, the second container 22 is provided with a second handle 24, and the handle seat 13 can support the second handle 24 when the second container 22 is mounted on the base 10. Alternatively, the base can be provided with a fixing structure capable of keeping the heating device in a certain position. The second handle 24 is provided to facilitate the user to lift and place the second container 22 and facilitate the user to operate. In the embodiment one, the heating device 60 has a matching support surface 61 with the first container 21 or the second container 22. When the transmission member 32 does not protrude from the avoiding hole 62, the heating device 60 does not protrude from the support surface 61. When the transmission member 32 protrudes from the avoiding hole 62, the heating device 60 protrudes from the support surface 61.

[0051] In the embodiment one, the power source 31 is an electric motor, and the cooking appliance further comprises a motor fixing plate 72 connected to the base 10 and a fixing member 50, the electric motor is connected to the motor fixing plate 72, and the fixing member 50 can support the transmission member 32 so that the transmission member 32 can rotate smoothly. The motor fixing plate 72 is provided to realize reliable fixing of the electric motor. Meanwhile, the motor fixing plate 72 can also realize heat insulation function. The first driving mechanism 30 further comprises a shaft sleeve 33 provided between the electric motor and the transmission member 32, and the transmission member 32 is connected to the electric motor through the shaft sleeve 33. The shaft sleeve 33 is provided to facilitate connection of the transmission member 32 and the electric motor, and realize synchronous rotation of the electric motor and the transmission member 32.

[0052] In the embodiment one, the heating device 60 is located below the first container 21 or the second container 22, and the first container 21 has a smooth bottom. The "smooth bottom" refers to a bottom in a planar or arc shape, and the bottom surface is not provided with a recess for avoiding the transmission member. Meanwhile, the "smooth bottom" also includes a bottom provided with patterns or having a certain roughness. When the first container is mounted on the base 10, the top surface of the transmission member 32 is flush with or lower than the surface of the heating device 60, and when the second container is mounted on the base 10, the top surface of the transmission member 32 is higher than the surface of the heating device 60.

[0053] The bottom of the second container 22 is provided with a recess, and the stirring structure 90 is connected to the transmission member 32 in the recess. Figure 6 As shown, due to the recess, the stirring structure 90 does not protrude from the bottom surface of the second container 22, so that the second container 22 can be placed stably on the platform surface. The base 10 comprises an outer pot 11 and a heat preservation cover 12 provided in the outer pot 11, and when the cooking appliance is a pressure cooker, the cooking appliance further comprises a pressure limiting valve and a sealing ring provided on the pot cover 80, and at least one of the first container 21, the second container 22 and the heat preservation cover 12 is provided with an anti-falling mechanism with the pot cover 80. The anti-falling mechanism refers to a mechanism for preventing the pot cover from being separated from the pot body when the first container or the second container is pressed, which can be a structure such as a pot tooth, a cover tooth or a caliper in the prior art.

[0054] In the 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 stewer, a bread maker, a frying machine, a multifunctional cooker, etc.

[0055] As shown in FIG. 1, in the embodiment of the cooking utensil provided in the present application, the cooking utensil comprises a base 6, a first container 7 and a second container 8. The first container 7 is arranged above the base 6, and the second container 8 is arranged above the first container 7.
