Description

Technical Field

[0001] This application relates to the field of electromechanical technology, and particularly to a cooking machine. Background Art

[0002] Currently, cooking machines have a heating function to heat the cooking materials in a container. To achieve the heating function, generally, a heating component is fixedly arranged on the outer wall surface of the container, and the heating component can generate heat to heat the container.

[0003] During the use of the cooking machine, it is inevitable that some liquids flow down the outer wall surface of the container onto the heating component. For example, during the process of adding liquid into the container before cooking, the liquid spills outside the container and flows down the outer wall surface of the container onto the heating component. Or, during the cooking process, the liquid in the container overflows or splashes out of the container and flows down the outer wall surface of the container onto the heating component. There are some high-voltage components in the heating component. After the high-voltage components get contaminated with liquid, there is a risk of short circuit or damage to the heating component.

[0035] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. In addition, it should be noted that for the convenience of description, only the parts related to the present application rather than all the structures are shown in the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0036] To reduce the risk of short - circuit or damage of the heating component, the present application provides a cooking machine, which includes a container, a base, a heating component, and a first driving component. The container is used to hold cooking materials. The base is used to support the container. The heating component is arranged on the base and can rise to approach the bottom of the container to heat the container or descend to move away from the bottom of the container. The first driving component can drive the heating component to rise or descend. The cooking machine provided by the present application will be specifically introduced below with Embodiment 1 and Embodiment 2 respectively.

[0037] Embodiment 1: Figure 1 It is a three - dimensional structure diagram of Embodiment 1 of the cooking machine of the present application. Figure 2 It is an exploded view of Embodiment 1 of the cooking machine of the present application. As Figure 1 and Figure 2 shown, the cooking machine includes a cup body 10 and a body main part 20. The cup body 10 is detachably arranged on the top of the body main part 20 to facilitate the transfer of cooking materials and the cleaning of the cup body 10. The body main part 20 is used to support the cup body 10 and provide power and heat to the cup body 10 to cooperate with the cup body 10 to cook the cooking materials. The cooking materials are, for example, soybeans and water, and through cooking operations, soy milk can be made. Figure 3 It is a cross - sectional view of the cup body 10 in Embodiment 1 of the cooking machine of the present application. Figure 4 It is a three - dimensional structure diagram of the cup body 10 in Embodiment 1 of the cooking machine of the present application. Figure 5 It is a three - dimensional structure diagram of the bottom of the cup body 10 in Embodiment 1 of the cooking machine of the present application. The bottom of the cup body 10 specifically refers to the bottom wall 112 and the connecting wall 1112 in the container housing 11. As Figures 3 to 5 shown, the cup body 10 includes a container housing 11, a container 12, a knife set 13, a transmission component 14, and a cup cover 15.

[0038] The container housing 11 includes a side wall 111 and a bottom wall 112. The side wall 111 and the bottom wall 112 enclose and form a first cavity 113 for accommodating the container 12. The top of the first cavity 113 is open to facilitate the user to operate on the container 12. Specifically, the side wall 111 includes a side - wall main body 1111 and a connecting wall 1112. The side - wall main body 1111 is generally in the shape of a tapered cylinder, and the outer diameter of the top end is smaller than that of the bottom end. The connecting wall 1112 is generally in the shape of a cylinder, is integrally formed with the bottom wall 112, is embedded at the bottom end of the side - wall main body 1111, and is detachably connected to the side - wall main body 1111. During the manufacturing process, the side - wall main body 1111 is one part, and the connecting wall 1112 and the bottom wall 112 are one part. After assembly, the connecting wall 1112 is fixedly connected to the side - wall main body 1111, and the two together form the side wall 111. The bottom wall 112 has a detachable design, which can make it more convenient to assemble the container 12 into the first cavity 113.

[0039] The container 12 is used to hold cooking materials. The container 12 can form a second cavity 121 with an open top, and the cooking materials are held in the second cavity 121. The user can load or pour out the cooking materials through the open top of the container 12, and can also clean the inner wall of the container 12 through the opening.

[0040] The container 12 is rotatably connected to the container housing 11 through a transmission assembly 14 so as to be able to rotate about its own axis. The transmission assembly 14 includes a cooking rotating shaft 141, a first bearing 142, and two second bearings 143. A first bearing hole 112c is provided at the center of the bottom wall 112. A bearing seat 123 protruding downward is provided at the center of the bottom of the container 12, and a second bearing hole 1231 penetrating the bottom of the container 12 is provided in the bearing seat 123. The bearing seat 123 of the container 12 is inserted into the first bearing hole 112c and is rotatably connected to the bottom wall 112 through the first bearing 142. The cooking rotating shaft 141 is inserted into the second bearing hole 1231 and is rotatably connected to the bearing seat 123 through the second bearing 143. The upper end of the cooking rotating shaft 141 extends into the container 12 and is connected to the cutter group 13. Both the first bearing 142 and the second bearing 143 are one-way bearings. A one-way bearing is a bearing that can achieve rotational connection in one direction and lock in the reverse direction. In this embodiment, when the cooking rotating shaft 141 rotates, one of the first bearing 142 and the second bearing 143 is in a rotational connection state, and the other is in a locked state. When the cooking rotating shaft 141 rotates forward, the first bearing 142 is in a locked state, and the second bearing 143 is in a rotational connection state. The cooking rotating shaft 141 only drives the cutter group 13 to rotate. At this time, the cooking machine performs a crushing operation to process the cooking materials into slurry. When the cooking rotating shaft 141 rotates in reverse, the first bearing 142 is in a rotational connection state, and the second bearing 143 is in a locked state. The cooking rotating shaft 141 drives both the cutter group 13 and the container 12 to rotate. At this time, the cooking machine performs a centrifugal operation on the slurry. By controlling the rotation direction of the cooking rotating shaft 141, the cooking machine can selectively perform a crushing operation or a centrifugal operation.

[0041] When the rotational speed of the container 12 reaches a predetermined rotational speed, the slurry runs towards the inner wall of the container 12 under the action of centrifugal force and contacts the inner wall of the container 12. At least part of the dregs (i.e., solid particles such as food residues in the slurry) adheres to the inner wall of the container 12, and the slurry (i.e., the liquid with high fluidity in the slurry) flows back to the bottom of the container 12, thereby realizing the centrifugal separation of the slurry. After the slurry is poured out, it does not need to be filtered, and the taste is improved. The slurry can be understood as a mixture of dregs and slurry obtained through methods such as crushing and grinding. In order to achieve a better drinking taste, it is necessary to separate the slurry from the dregs. Most of the dregs are insoluble dietary fiber, and the dregs have a certain viscosity and can closely adhere to the inner wall of the container 12 under the centrifugal state. For example, when a blender is used to make fruit juice, after the fruit is broken into slurry and then centrifuged, the fruit dregs will adhere to the inner wall of the container 12, enabling the quick separation of the fruit dregs from the fruit juice. The fruit juice can be directly drunk after being poured out of the container 12, while the fruit dregs remain in the container 12 without manual filtration. Another example is that when a blender is used to make soy milk, the beans and water are mixed in a certain proportion. After the beans are broken to form soy milk, and then centrifuged, the soybean dregs adhere to the inner wall of the container 12, separating the soybean dregs from the soy milk, thereby obtaining relatively pure soy milk without manual filtration and with a better drinking taste. The above-mentioned predetermined rotational speed can be 500 revolutions per minute to 5000 revolutions per minute. The value of the predetermined rotational speed can be set according to the quantity and type of cooking materials.

[0042] The container 12 is arranged inside the container housing 11, so that the container 12 is isolated from the outside world, which can prevent accidents from occurring when the container 12 rotates.

[0043] The cutter group 13 is arranged in the second cavity 121 and at the top of the cooking rotating shaft 141, and can rotate under the drive of the cooking rotating shaft 141 to perform a crushing operation on the cooking materials to obtain slurry. The cutter group 13 includes a cutting tool 131 and a grinding tool 132. The cutting tool 131 is used to cut the cooking materials. The bottom of the container 12 is provided with grinding teeth 122, and the grinding tool 132 is used to cooperate with the grinding teeth 122 to grind the cut cooking materials.

[0044] The cup cover 15 is detachably disposed on the top of the container housing 11 and the container 12. The cup cover 15 includes an outer cover 151, a third bearing seat 152, an inner cover 153, a hollow column 154, and a third bearing 155. The outer cover 151 is snap-connected to the container housing 11 to seal the top opening of the container housing 11. The third bearing seat 152 protrudes downward from the central area of the outer cover 151. The inner cover 153 is embedded in the opening at the top of the container 12 and is relatively fixed to the container 12 by friction and is non-rotatable relative to the container 12. The hollow column 154 is fixed to the center of the inner cover 153 and is rotatably connected to the third bearing seat 152 through the third bearing 155. The hollow column 154 communicates the second cavity 121 with the external environment so that the hot air in the container 12 can escape through the hollow column 154. The third bearing 155 is a bi-directional bearing. Due to the arrangement of the third bearing 155, when the cooking machine performs a centrifugal operation, the inner cover 153 can rotate following the container 12 without affecting the rotation of the container 12. Also, since the inner cover 153 and the outer cover 151 are inseparable, the container 12 and the container housing 11 can be opened or capped synchronously. By providing the cup cover 15, liquid splashing during the operation of the cooking machine can be avoided. In this embodiment, the cup cover 15 is not necessary.

[0045] Figure 6 It is a cross-sectional view of the first embodiment of the cooking machine of the present application. Figure 7 It is an exploded view of the body main body 20 in the first embodiment of the cooking machine of the present application. As Figure 6 and Figure 7 shown, the body main body 20 includes a base 21, a heating component 22, a first driving component 23, a second driving component 24, and a locking component 25.

[0046] The container housing 11 is placed on the base 21. The base 21 is used to support the container 12 through the container housing 11 and is also used to install other components of the body main body 20. The base 21 has a cavity 211 to accommodate other components. The top of the cavity 211 is open to expose the heating component 22 from the base 21 so as to contact the container 12. The base 21 includes an upper housing 212, a lower housing 213, and a mounting seat 214. The upper housing 212 and the lower housing 213 are detachably connected and jointly form the cavity 211 after assembly. The mounting seat 214 is accommodated in the cavity 211 and is detachably connected to the upper housing 212 for installing other components. When assembling the cooking machine, other components can be first assembled to the mounting seat 214, then the mounting seat 214 can be assembled to the upper housing 212, and then the lower housing 213 can be assembled to the upper housing 212. Compared with setting the mounting seat 214 as an integral structure, it can facilitate the assembly operation.

[0047] The heating component 22 is disposed on the base 21 and can move upward to approach the bottom of the container 12 or move downward to move away from the bottom of the container 12. Specifically, the heating component 22 is located below the container 12, at least a part of it is disposed in the cavity 211 of the base 21, and is movably connected to the base 21 so as to be able to move up and down relative to the base 21.

[0048] Figure 8 Yes Figure 6 is the sectional view taken along line A-A in. As Figure 6 and Figure 8 shown, in order to enable the heating component 22 to move along a predetermined path, the base 21 has a first guiding portion 215, and the heating component 22 has a second guiding portion 226. The second guiding portion 226 is slidably engaged with the first guiding portion 215 in the moving direction of the heating component 22. Specifically, the first guiding portion 215 and the second guiding portion 226 are respectively disposed on a pair of opposite surfaces of the base 21 and the heating component 22. The first guiding portion 215 is a cylinder and extends in the moving direction of the heating component 22. The second guiding portion 226 is a groove and extends in the moving direction of the heating component 22. In this embodiment, the first guiding portion 215 is disposed on the wall of the cavity 211 of the base 21. The second guiding portion 226 is disposed on the outer edge of the heating component 22. Of course, in other embodiments, the positions of the first guiding portion 215 and the second guiding portion 226 can also be interchanged, that is, the first guiding portion 215 is disposed on the heating component 22, and the second guiding portion 226 is disposed on the base 21.

[0049] The heating component 22 can also generate heat by itself to heat the container 12 when approaching the bottom of the container 12, and further heat the cooking materials in the container 12. Further, when the heating component 22 abuts against the bottom of the container 12, it heats the container 12 to improve the heat transfer efficiency.

[0050] Figure 9 is a three-dimensional structural schematic diagram of the heating component 22 in the first embodiment of the food processor of the present application. As Figure 5 and Figure 9As shown in the figure, in order to enable the heating component 22 to heat the bottom of the container 12, a through hole 112a is provided on the bottom wall 112 for at least a part of the heating component 22 to extend into the first cavity 113 and fit with the bottom of the container 12. Specifically, the number of through holes 112a on the bottom wall 112 is several. The upper surface of the heating component 22 has heat generating protrusions 2211a corresponding one by one to the through holes 112a. Grooves 2211b matching the shape of the bottom wall 112 are formed between the heat generating protrusions 2211a. When the heating component 22 approaches the bottom of the container 12, the heat generating protrusions 2211a can pass through the through holes 112a on the bottom wall 112, and at least part of the bottom wall 112 is received in the grooves 2211b. In this embodiment, the bottom wall 112 has three spokes 112b distributed radially. Through holes 112a are formed between two adjacent spokes 112b. The shape of each through hole 112a is generally fan-shaped. The shape and size of the heat generating protrusions 2211a match those of the through holes 112a. When the heating component 22 approaches the bottom of the container 12, the spokes 112b are received in the grooves 2211b between adjacent heat generating protrusions 2211a. A number of through holes 112a are provided on the bottom wall 112, so that the heating component 22 can contact the bottom of the container 12 as much as possible, thereby improving the heating efficiency.

[0051] Figure 10 It is a three-dimensional structure diagram of the heating component 22 from another perspective in the first embodiment of the food processor of the present application. Figure 11 It is an exploded view of the heating component 22 in the first embodiment of the food processor of the present application. Figure 12 It is an exploded view of the heating unit 221 in the heating component 22 in the first embodiment of the food processor of the present application. As Figures 10 to 12 shown, the heating component 22 includes a heating unit 221, a lifting support 222, five elastic members 223, and five fasteners 224.

[0052] The heating unit 221 is located on the side of the lifting support 222 facing the container 12. The heating unit 221 can generate heat by itself. The heating unit 221 includes a heat transfer main body 2211, nine heating elements 2212, a heat insulation member 2213, a bracket 2214, and a sensor 2215.

[0053] The heat transfer main body 2211 has thermal conductivity and is made of a heat conductive material, for example, aluminum alloy. The above-mentioned heat generating protrusions 2211a are provided on the side of the heat transfer main body 2211 facing the container 12. The heat transfer main body 2211 is generally annular. Five guide posts 2211c also protrude from the heat transfer main body 2211. The five guide posts 2211c extend towards the side away from the container 12 and are spaced apart around the axis of the heat transfer main body 2211.

[0054] The heating element 2212 is thermally coupled to the heat transfer body 2211 and can generate heat when powered on. The heating element 2212 can be a heating tube inserted into the heat transfer body 2211. The heating tube is an optional existing technology. Nine heating elements 2212 are evenly distributed on the heat transfer body 2211 around the axis of the heat transfer body 2211 to make the temperature on the heat transfer body 2211 uniform. Of course, the heating element 2212 can also be one and in a ring shape, surrounding outside the axis of the heat transfer body 2211.

[0055] The bracket 2214 is used to stably fix the heat insulation member 2213 on the heat transfer body 2211. The heat insulation member 2213 is padded between the heat transfer body 2211 and the bracket 2214. The bracket 2214 is detachably arranged on the side of the heat transfer body 2211 facing away from the container 12. The heat insulation member 2213 is made of heat insulation material to avoid the heat on the heat transfer body 2211 being transferred to the side facing away from the container 12. On the one hand, it can protect the components on the body main body 20, and on the other hand, it can reduce the heat loss on the heat transfer body 2211. The bracket 2214 is generally in a ring shape, and three notches 2214a are provided on its outer peripheral edge. The three notches 2214a are circumferentially spaced on the bracket 2214.

[0056] The sensor 2215 is arranged on the heat transfer body 2211 to detect the temperature on the heat transfer body 2211, or to detect the temperature of the container 12 when the heat transfer body 2211 is in contact with the container 12.

[0057] The process of assembling the heating unit 221 is as follows: Assemble the heating element 2212 and the sensor 2215 onto the heat transfer body 2211; then assemble the heat insulation member 2213 onto the heat transfer body 2211; then assemble the bracket 2214 onto the heat transfer body 2211.

[0058] The lifting support member 222 includes a lifting support main body 2221 and four support blocks 2222. The lifting support main body 2221 is generally in the shape of a hollow disk, and three notches 2221a are provided on its outer peripheral edge. The three notches 2221a of the lifting support main body 2221 correspond to the three notches 2214a of the support bracket 2214 one by one. After the heating assembly 22 is assembled, each notch 2221a and the corresponding notch 2214a are combined to form the second guiding portion 226 described above. The lifting support main body 2221 is further provided with five through holes 2221b. The five through holes 2221b correspond to the five guiding columns 2211c one by one. After the heating assembly 22 is assembled, each guiding column 2211c is inserted into the corresponding through hole 2221b to guide the relative movement of the lifting support member 222 and the heating element 221 in the extending direction of the guiding column 2211c. The four support blocks 2222 are located on the side of the lifting support main body 2221 facing away from the heating element 221, and each support block 2222 is used to abut against the first surface 2331 of the transmission member 233 described below.

[0059] The relative two ends of each elastic member 223 are respectively elastically abutted / connected to the heating element 221 and the lifting support member 222. Specifically, the five elastic members 223 correspond to the five guiding columns 2211c one by one. Each elastic member 223 is sleeved outside the corresponding guiding column 2211c, and the relative two ends are respectively elastically abutted / connected to the heat transfer main body 2211 and the lifting support main body 2221. The elastic member 223 can be a spring.

[0060] The fastener 224 is connected to the heating element 221 and is used to abut against the lifting support member 222. Specifically, the five fasteners 224 correspond to the five guiding columns 2211c one by one. Each fastener 224 is located on the side of the lifting support main body 2221 facing away from the heating element 221 and is fixed at the end of the corresponding guiding column 2211c. The fastener 224 can be a nut and is threadedly connected to the guiding column 2211c.

[0061] The process of assembling the heating assembly 22 is as follows: First, the five elastic members 223 are respectively sleeved on the five guiding columns 2211c of the heating element 221; then the lifting support member 222 is assembled onto the heating element 221 so that the five guiding columns 2211c pass through the five through holes 2221b; and the five fasteners 224 are respectively fixed at the ends of the five guiding columns 2211c.

[0062] In this embodiment, when the heating assembly 22 is not subject to external force, the elastic member 223 is in a compressed state. Under the elastic force of the elastic member 223, the fastener 224 abuts against the lifting support main body 2221. Thus, the heating assembly 22 has a compact structure, and the relative positions of the components inside the heating assembly 22 are stable. The heating unit 221 and the lifting support 222 will not move relative to each other (when not subject to external force). When the fastener 224 is a nut, the degree of compression of the elastic member 223 can be adjusted by tightening or loosening the nut.

[0063] Driven by the first driving assembly 23, the lifting support 222 moves towards the container 12. At this time, the lifting support 222 drives the heating unit 221 to move towards the container 12 through the elastic member 223. After the heating unit 221 contacts the container 12 and stops moving, the lifting support 222 will still move slightly towards the container 12, causing the elastic member 223 to be further compressed. The elastic force towards the container 12 is applied to the heating unit 221, so that the heating unit 221 closely adheres to the container 12. Even if the container 12 moves slightly in some cases, the heating unit 221 can always closely adhere to the container 12 and stably heat the container 12. Through the above structural design, the heating assembly 22 can elastically abut against the container 12 when contacting the container 12, so that the heating assembly 22 better fits the container 12 and improves the heat transfer efficiency.

[0064] As Figure 6 and Figure 7As shown, the first driving assembly 23 is arranged on the base 21, and can drive the heating assembly 22 to rise or fall. Specifically, the first driving assembly 23 is arranged on the mounting seat 214 and is located below the heating assembly 22. The first driving assembly 23 may include a transmission member 233, a gear 232 and a first motor 231. The transmission member 233 is rotatably arranged on the mounting seat 214 and can rotate around the axis L1. The transmission member 233 has a first surface 2331. The first surface 2331 is located outside the axis L1, extends around the axis L1, and at the same time extends in the direction of the axis L1 to form a helical surface. The gear 232 is rotatably arranged on the mounting seat 214 and meshes with the transmission member 233. The first motor 231 is arranged on the mounting seat 214, and the output shaft of the first motor 231 is connected to the gear 232. The first motor 231 can rotate forward and reverse to drive the transmission member 233 to rotate along the first direction D1 or the second direction D2. The first direction D1 is opposite to the second direction D2. The first surface 2331 contacts the heating assembly 22 in a direction inclined to the axis L1, so as to convert the rotational motion of the transmission member 233 into the linear motion of the heating assembly 22. When the transmission member 233 rotates along the first direction D1, the heating assembly 22 moves downward under the action of gravity and moves away from the container 12. When the transmission member 233 rotates along the second direction D2, the heating assembly 22 moves upward under the push of the first surface 2331, approaches until it contacts the container 12. The number of the first surfaces 2331 can be several, and the several first surfaces 2331 are arranged at intervals around the axis L1. In this way, the force on the heating assembly 22 is more uniform, and it is prevented from getting stuck with the base 21 during the rising process.

[0065] The second driving assembly 24 is disposed on the mounting seat 214 and is located below the heating assembly 22. The heating assembly 22 has an escape hole 225 (see FIG. Figure 10 ), a part of the second drive assembly 24 passes through the avoidance hole 225 and is connected to the container 12, and the second drive assembly 24 is used to drive the container 12 to rotate. Specifically, the second drive assembly 24 is detachably connected to the cooking shaft 141, and is used to drive the container 12 and / or the knife group 13 to rotate. A first connector 144 is fixed to the bottom end of the cooking shaft 141. The second drive assembly 24 includes a second motor 241 and a second connector 242. The second motor 241 is arranged on the mounting seat 214. The second connector 242 is fixed to the output shaft of the second motor 241. When the cup body 10 is arranged on the base 21, the first connector 144 and the second connector 242 are plugged and matched to form a coupling, connecting the cooking shaft 141 with the output shaft of the second motor 241, so that the second motor 241 can drive the cooking shaft 141 to rotate. The second motor 241 can rotate forward and reverse, thereby driving the cooking shaft 141 forward and reverse.

[0066] When the cooking machine performs a centrifugation operation, if the heating component 22 is in contact with the bottom of the container 12, it will affect the rotation of the container 12. For this reason, the first driving component 23 is used to drive the heating component 22 to approach and contact the container 12 during at least part of the period when the container 12 stops rotating, and is used to drive the heating component 22 away from the container 12 before the container 12 rotates. For example, during the operation of the second driving component 24 to drive the container 12 to rotate, the user cannot select the heating mode. Alternatively, it can be preset that after the heating component 22 finishes heating, the first driving component 23 immediately drives the heating component 22 away from the container 12. Alternatively, when the user selects the centrifugation mode, the controller (not shown in the figure) of the cooking machine can determine whether the heating component 22 is in a separated state from the container 12. If so, it controls the second driving component 24 to act to drive the container 12 to rotate, otherwise it controls the first driving component 23 to act so that the heating component 22 is separated from the container 12.

[0067] The latch component 25 is arranged on the base 21 and is used to cooperate with the card slot 1112a at the bottom of the container housing 11, so that the container housing 11 can be detachably arranged on the base 21. Thus, after the cooking is completed, the container housing 11 together with the container 12 can be removed from the base 21 to facilitate pouring the slurry or cleaning the container 12.

[0068] Beneficial effects:

[0069] In this embodiment, the heating component 22 is movably arranged on the base 21 and can be driven by the first driving component 23 to rise or fall, and then approach or move away from the container 12, and heat the container 12 when approaching the container 12. When the cooking machine is in a state without heating, the heating component 22 can be kept separated from the container 12. Even if there is liquid flowing down along the outer wall surface of the container 12, it will not directly flow onto the heating component 22. Thus, the probability of the heating component 22 being stained with liquid can be reduced, thereby reducing the risk of short circuit or damage to the heating component 22.

[0070] Since the container 12 can rotate around its own axis and the heating component 22 can approach or move away from the container 12, the first driving component 23 can drive the heating component 22 away from the container 12 before the container 12 rotates, and drive the heating component 22 to approach and contact the container 12 during at least part of the period when the container 12 stops rotating. Thus, it is possible to prevent the heating component 22 from affecting the rotation of the container 12. By supporting the container 12 through the base 21 and arranging the heating component 22 on the base 21, the heating component 22 can approach or move away from the bottom of the container 12, so that the heating component 22 can heat the bottom of the container 12. The cooking materials in the container 12 converge at the bottom of the container 12 under the action of gravity. Heating the bottom of the container 12 by the heating component 22 can transfer heat to the cooking materials faster.

[0071] The cooking machine is also provided with a container housing 11. The container housing 11 includes a side wall 111 and a bottom wall 112. The side wall 111 and the bottom wall 112 enclose a first cavity 113 for accommodating the container 12. The container housing 11 is placed on the base 21, and the base 21 supports the container 12 through the container housing 11. Thus, in the application scenario where the container 12 can rotate, the container housing 11 isolates the container 12 from the outside world and avoids accidental injury accidents.

[0072] A through hole 112a is provided on the bottom wall 112. At least a part of the heating component 22 extends into the first cavity 113 through the through hole 112a and fits against the bottom of the container 12. Thus, even if the container housing 11 blocks it, the container 12 can still be heated.

[0073] The number of through holes 112a on the bottom wall 112 is several. The upper surface of the heating component 22 has heat generating protrusions 2211a corresponding to the through holes 112a one by one. Grooves 2211b matching the shape of the bottom wall 112 are formed between the heat generating protrusions 2211a. When the heating component 22 approaches the bottom of the container 12, the heat generating protrusions 2211a can pass through the through holes 112a on the bottom wall 112, and at least part of the bottom wall 112 is received in the grooves 2211b. Thus, while ensuring that the fitting area between the heating component 22 and the container 12 remains unchanged, by providing several through holes 112a, compared with only providing one through hole 112a, the structural strength of the bottom wall 112 can be improved, thereby stably supporting the container 12.

[0074] Variant example:

[0075] In other embodiments, the third bearing 155 can also be a one-way bearing. When the cooking rotating shaft 141 rotates forward (when the cooking machine performs a crushing operation), the third bearing 155 is in a locked state. When the cooking rotating shaft 141 rotates backward (when the cooking machine performs a centrifugal operation), the third bearing 155 is in a rotatably connected state. Additionally, when the third bearing 155 is a one-way bearing, it also functions as the first bearing 142 in this embodiment. At this time, the first bearing 142 can be a one-way bearing or a two-way bearing. That is, at least one of the first bearing 142 and the third bearing 155 is a one-way bearing.

[0076] In other embodiments, to make the heating component 22 better fit the container 12, the cooking machine can also include a heat conductive elastic pad (not shown in the figure). The heat conductive elastic pad is provided on the heating component 22 or the container 12. When the heating component 22 contacts the container 12, the heat conductive elastic pad can fill the gap between the two. The heat conductive elastic pad has elasticity and heat conductivity. The heat conductive elastic pad can be a heat conductive silicone sheet. The heat conductive silicone sheet is a heat conductive medium material synthesized by using silicone as the base material, adding various auxiliary materials such as metal oxides, and through a special process, and can be selected from the prior art.

Figure 13 It is an exploded view of Embodiment 2 of the food processor of the present application. Figure 14 It is an exploded view of Embodiment 2 of the food processor of the present application from another perspective.

[0079] As Figures 12 to 14 shown, the food processor includes: a cup body 30 and a body main body 40. The cup body 30 is detachably arranged on the top of the body main body 40 to facilitate the transfer of cooking materials and the cleaning of the cup body 30. The body main body 40 is used to support the cup body 30 and provide power and heat to the cup body 30 to cooperate with the cup body 30 to cook the cooking materials.

[0080] Figure 15 It is a cross - sectional view of Embodiment 2 of the food processor of the present application. Figure 16 It is Figure 15 an enlarged view of the partial view B in

[0081] As Figure 15 and Figure 16 shown, the cup body 30 includes a container outer shell 31, a container 32, a second cooking rotating shaft 33, a bearing 34, a cup cover 35, and a knife set 36.

[0082] The container outer shell 31 includes a side wall, and a first cavity 311 for accommodating the container 32 is formed by enclosing the side surface of the side wall. The bottom of the container outer shell 31 is open, so that the heating component 42 can enter the first cavity 311 from the opening and fit with the bottom of the container 32. The container outer shell 31 is generally in the shape of a conical cylinder, and the outer diameter of the upper end is smaller than the outer diameter of the lower end.

[0083] The container 32 is accommodated in the first cavity 311. The container 32 forms a second cavity 321 with an open top, and the second cavity 321 is used to hold cooking materials. A slot 322 is provided in the center of the bottom wall of the container 32. The slot 322 is recessed on the outer wall surface of the container 32, on the side facing the second cavity 321. The slot 322 is cylindrical. A plurality of clamping portions 322a are convexly provided on the side wall of the slot 322. Each clamping portion 322a extends in the axial direction of the slot 322. The plurality of clamping portions 322a are evenly distributed in the circumferential direction of the slot 322. A clamping groove 322b is formed between two adjacent clamping portions 322a. The bottom surface of the slot 322 is recessed on the side facing the second cavity 321 to form a receiving groove 323. The receiving groove 323 is cylindrical and is coaxially arranged with the slot 322. The bottom surface of the receiving groove 323 forms a third bearing hole 324 penetrating the bottom wall of the container 32.

[0084] The second cooking rotating shaft 33 is inserted into the third bearing hole 324 and is rotatably connected to the container 32 through the bearing 34. The bearing 34 is a two-way bearing, and the second cooking rotating shaft 33 can rotate forward and backward relative to the container 32. Specifically, the second cooking rotating shaft 33 includes a first rotating shaft 331 and a first connector 332. The first rotating shaft 331 is inserted into the bearing hole 324 and is rotatably connected to the container 32 through the bearing 34. The top end of the first rotating shaft 331 is accommodated in the second cavity 321. The first connector 332 is fixed to the bottom end of the first rotating shaft 331. The first connector 332 is located in the receiving groove 323. The outer diameter of the first connector 332 is smaller than the inner diameter of the receiving groove 323, so that the first connector 332 can rotate with the first rotating shaft 331. To prevent the container 32 from leaking, a sealing material is stuffed between the first rotating shaft 331 and the container.

[0085] The knife set 36 is disposed in the second cavity 321 and is fixed to the top end of the first rotating shaft 331. The knife set 36 can refer to the knife set 13 in the first embodiment and will not be elaborated here.

[0086] The cup cover 35 is detachably covered on the tops of the container housing 31 and the container 32. The cup cover 35 includes an outer cover 351, a bearing seat 352, an inner cover 353, a hollow column 354, and a bearing 355. The outer cover 351 is snap-connected to the container housing 31 to cover the top opening of the container housing 31. The bearing seat 352 protrudes downward from the central area of the outer cover 351. The inner cover 353 is embedded in the opening at the top of the container 32 and is relatively fixed to the container 32 by friction and is non-rotatable relative to the container 32. The hollow column 354 is fixed to the center of the inner cover 353 and is rotatably connected to the bearing seat 352 through the bearing 355. The bearing 355 is a two-way bearing.

[0087] The body main body 40 includes a base 41, a heating component 42, a first driving component 43, a motor 44, a first bearing seat 45, a second bearing seat 46, a first bearing 471, a second bearing 472, a first cooking rotating shaft 48, and a plug 49.

[0088] The container housing 31 is placed on the base 41, and the part of the base 41 located at the bottom opening of the container housing 31 supports the container 32.

[0089] The heating component 42 and the first driving component 43 can be referred to the introduction in the first embodiment and will not be elaborated here.

[0090] The motor 44 is an example of the second driving component. The motor 44 is disposed on the base 41 and can rotate forward and backward.

[0091] The first bearing seat 45 is located at the central position on the top of the base 41 and is an integral structure with the base 41. In other embodiments, it can also be a split structure. The first bearing seat 45 is provided with a first bearing hole 451 with an open top end.

[0092] The second bearing seat 46 is a hollow cylindrical shape, and the outer diameter of its upper end is larger than that of its lower end. A second bearing hole 461 is formed at the upper end of the second bearing seat 46. The lower end of the second bearing seat 46 is inserted into the first bearing hole 451 and is rotatably connected to the first bearing seat 45 through the first bearing 471.

[0093] The first cooking rotating shaft 48 is inserted into the bearing hole 461 and is rotatably connected to the second bearing seat 46 through the second bearing 472. The first cooking rotating shaft 48 includes a second rotating shaft 481 and a second connector 482. The bottom end of the second rotating shaft 481 is connected to the output shaft of the motor 44 and rotates under the drive of the motor 44. The second connector 482 is fixedly arranged at the top end of the second rotating shaft 481 and can be inserted and matched with the first connector 332 in the vertical direction to form a coupling to connect the first rotating shaft 331 and the second rotating shaft 481. Both the first bearing 471 and the second bearing 472 are one-way bearings. When one of the first bearing 471 and the second bearing 472 rotates, the other is locked.

[0094] The plug 49 is generally cylindrical and is sleeved on the top end of the second bearing seat 46. The outer shape of the plug 49 matches the inner wall shape of the slot 322 so that the plug 49 can be inserted and matched with the slot 322 in the vertical direction. The connection method between the plug 49 and the slot 322 is similar to the connection method between the first connector 332 and the second connector 482. The plug 49 and the second bearing seat 46 can be a split structure or an integral structure.

[0095] Before cooking, align the slot 322 at the bottom of the container 32 with the plug 49 on the body mainframe 40 so that the slot 322 and the plug 49 are inserted and matched in the vertical direction, thereby placing the container 32 on the top of the body mainframe 40. When the slot 322 and the plug 49 are inserted and matched, the second cooking rotating shaft 33 and the first cooking rotating shaft 48 are automatically inserted and matched. Then, set the container housing 31 on the top of the body mainframe 40 to sleeve outside the container 32. After adding cooking materials to the container 32, cover the cup cover 35 on the container housing 31 and the container 32. After cooking is completed, disassemble the cup cover 37, the container housing 31, and the container 32 in sequence, transfer the cooking materials in the container 32, and clean the container 32.

[0096] The cooking machine can heat the cooking materials. Specifically, the first driving component 43 acts to drive the heating component 42 to rise until the heating component 42 fits against the bottom of the container 32. After the heating component 42 heats the container 32 for a predetermined time, the first driving component 43 acts to drive the heating component 42 to descend and move away from the container 32.

[0097] The cooking machine can crush cooking materials. Specifically, the output shaft of the motor 44 rotates in the first direction. At this time, the second bearing 472 is in a rotating connection state, while the first bearing 471 is in a locked state, and the container 32 cannot rotate. The motor 44 drives the cutter group 36 to rotate through the first cooking rotating shaft 48 and the second cooking rotating shaft 33 to cut and grind the cooking materials. During the grinding process of the cooking materials, since the container 32 cannot rotate, the grinding effect can be improved.

[0098] The cooking machine can centrifuge cooking materials. The output shaft of the motor 44 rotates in the second direction opposite to the first direction. At this time, the first bearing 471 is in a rotating connection state, the second bearing 472 is in a locked state, and the motor 44 drives the cutter group 36 and the container 32 to rotate together through the first cooking rotating shaft 48 and the second cooking rotating shaft 33 to centrifuge the cooking materials.

[0099] Beneficial effects:

[0100] The cooking machine includes a container 32, a base 41, a heating component 42, and a first driving component 43. The container 32 is used to hold cooking materials. The base 41 is used to support the container 32. The heating component 42 is arranged on the base 41 and can rise to approach the bottom of the container 32 to heat the container 32, or descend to move away from the bottom of the container 32. The first driving component 43 can drive the heating component 42 to rise or descend. Thus, in this embodiment, the probability of the heating component 42 being stained with liquid can be reduced, thereby reducing the risk of short - circuit or damage of the heating component 42. In addition, under the action of gravity, the cooking materials in the container 32 gather at the bottom of the container 32. The heating component 42 heats the bottom of the container 32, and the heat can be transferred to the cooking materials faster.

[0101] Since the container 32 can rotate around its own axis and the heating component 42 can approach or move away from the container 32, the first driving component 43 can drive the heating component 42 to move away from the container 32 before the container 32 rotates, and drive the heating component 42 to approach and contact the container 32 during at least part of the period when the container 32 stops rotating. Thus, the influence of the heating component 42 on the rotation of the container 32 can be avoided.

[0102] The cooking machine further includes a container housing 31. The container housing 31 includes side walls, and a first cavity 311 for accommodating the container 32 is formed by enclosing the side walls. Thus, the container housing 31 can isolate the container 32 from the outside world, and accidents can be avoided when the container 32 rotates at a high speed.

[0103] In the first embodiment of the cooking machine, the container housing 11 bears the container 12 through the bottom wall 112. Due to the shielding of the bottom wall 112, the surface of the heating component 22 is provided with a groove 2211b to avoid the bottom wall 112. The groove 2211b reduces the contact area between the heating component 22 and the container 12. In this embodiment, the container housing 31 is placed on the base 41, and the base 41 supports the container 32 at the open part of the bottom of the container housing 31. The bottom of the container housing 31 is open, so that the heating component 42 can enter the first cavity 311 from the opening and fit with the bottom of the container 32. Since the container housing 31 has no bottom wall, there is no blockage between the heating component 42 and the container 32, and the side surface of the heating component 42 facing the container 32 can be set as a flat surface. Compared with the first embodiment of the cooking machine, this embodiment can increase the contact area between the heating component 42 and the container 32 and improve the efficiency of heat transfer.

[0104] The cooking machine further includes a first bearing 471, a second bearing 472, a first cooking rotating shaft 48, a second cooking rotating shaft 33, a first bearing seat 45 and a second bearing seat 46. The first bearing seat 45 and the second bearing seat 46 are coaxially arranged at the open part of the bottom of the base 41 where the container housing 31 is located. The first bearing seat 45 is provided with a first bearing hole 451. The lower end of the second bearing seat 46 is inserted into the first bearing hole 451 and is rotatably connected to the first bearing seat 45 through the first bearing 471. The second bearing seat 46 is provided with a second bearing hole 461, and the first cooking rotating shaft 48 is inserted into the second bearing hole 461 and is rotatably connected to the second bearing seat 46 through the second bearing 472. A third bearing hole 324 penetrating the bottom of the container 32 is provided at the center of the bottom of the container 32, and the second cooking rotating shaft 33 is inserted into the third bearing hole 324. The lower end of the second cooking rotating shaft 33 is detachably connected to the upper end of the first cooking rotating shaft 48, and the upper end of the second cooking rotating shaft 33 extends into the container 32. Thus, this embodiment provides a specific way for the base 41 to support the container 32. When the container 32 is arranged on the base 41, the weight of the container 32 is sequentially transmitted to the base 41 through the second cooking rotating shaft 33, the first cooking rotating shaft 48, the second bearing 472, the second bearing seat 46, the first bearing 471 and the first bearing seat 45. Thus, the base 41 can stably support the container 32. At the same time, the container 32 can also rotate around its own axis, so that the cooking machine has a centrifugal function. In addition, the container 32 can be detachably arranged on the body main body 40, which is convenient for transferring cooking materials and cleaning the container 32.

[0105] The outer wall surface and the center of the bottom of the container 32 are provided with slots 322. The cooking machine includes a plug 49, and the plug 49 is sleeved on the upper end of the second bearing seat 46 and is detachably connected to the container 32 through the slots 322. Thus, a part of the weight of the container 32 can be sequentially transmitted to the base 41 through the plug 49, the second bearing seat 46, the first bearing 471 and the first bearing seat 45. In some application scenarios, by appropriately adjusting the size, the entire weight of the container 32 can act on the plug 49 to avoid axial force on the first cooking rotating shaft 48. Variation:

[0106] In this embodiment, the container 32 rotates only in one direction. Therefore, the bearing 355 in the cup cover 35 is not limited to a bidirectional bearing and can also be a unidirectional bearing. When the bearing 355 is a unidirectional bearing, it is necessary to satisfy that when the output shaft of the motor 44 rotates in the first direction (when the cooking machine performs a crushing operation), the bearing 355 is in a locked state, and when the output shaft of the motor 44 rotates in the second direction (when the cooking machine performs a centrifugal operation), the bearing 355 is in a rotatably connected state. In addition, when the bearing 355 is a unidirectional bearing, it also functions as the first bearing 471. When the cooking machine performs a crushing operation, the container 32 will not rotate under the restriction of the bearing 355. At this time, the first bearing 471 can be a unidirectional bearing or a bidirectional bearing. That is, at least one of the first bearing 471 and the bearing 355 is a unidirectional bearing.

[0107] The above are only the embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present application by the same token.
