Technical Field

[0001] The present application relates to the field of electromechanical technology, and in particular to a food processor and a heating component thereof. Background Art

[0002] Currently, food processors have a heating function to heat the food materials in a container. To achieve this, a heating component is usually fixedly arranged on the outer wall of the container, and the heating component can generate heat to heat the container.

[0003] During the use of a food processor, some liquid may inevitably flow along the outer walls of the container and onto the heating element. For example, while adding liquid to the container before cooking, liquid may spill outside the container and flow along the outer walls onto the heating element. Alternatively, during cooking, liquid may overflow or splash out of the container and flow along the outer walls onto the heating element. The heating element contains high-voltage components. If these components come into contact with liquid, there is a risk of short circuiting or damage to the heating element. Summary of the Invention

[0011] Furthermore, the heating unit has a first snap-fit ​​portion, the inner peripheral side wall of the locking member has a second snap-fit ​​portion, and the first snap-fit ​​portion and the second snap-fit ​​portion are snap-fitted.

[0012] Furthermore, the support member has a first guide portion, which is used to slideably cooperate with the second guide portion of the base of the food processor to guide the movement of the support member.

[0013] Furthermore, the first guide portion is a groove or a column extending in the moving direction of the support member.

[0044] To reduce the risk of short circuits or damage to the heating assembly, this application provides a heating assembly for a food processor, comprising a support member and a heating unit. Driven by the food processor's main unit, the support member can move toward or away from the food processor's container. The heating unit is disposed on the support member so that when the support member approaches the container, it contacts and heats the container.

[0045] To reduce the risk of short circuiting or damage to the heating assembly, the present application also provides a food processor comprising: a container, the aforementioned heating assembly, and a main unit. The container is used to hold cooking ingredients. The main unit is used to drive the support member in the heating assembly.

[0046] The food processor and heating assembly of the present application are described in detail below with reference to Examples 1 and 2.

[0047] Example 1:

[0048] Figure 1 and Figure 2 They are the three-dimensional structural diagram and exploded diagram of the food processor. Figure 1 and Figure 2 As shown, the food processor includes a cup 10 and a main body 20. The cup 10 is detachably mounted on top of the main body 20, facilitating the transfer of cooking ingredients and cleaning. The main body 20 supports the cup 10 and provides power and heat to the cup 10, thereby cooperating with the cup 10 to cook the cooking ingredients. The cooking ingredients, for example, are soybeans and water, which can be used to make soy milk.

[0049] Figure 3 and Figure 4 They are respectively a cross-sectional view and a three-dimensional structural schematic diagram of the cup body 10. Figure 5 1 is a schematic diagram of the three-dimensional structure of the bottom of the cup body 10, and the bottom of the cup body 10 specifically refers to the bottom wall 112 and the connecting wall 1112 in the container shell 11. Figures 3 to 5 As shown, the cup body 10 includes a container shell 11, a container 12, a knife group 13, a transmission assembly 14 and a cup lid 15. The container shell 11 includes a side wall 111 and a bottom wall 112. The side wall 111 and the bottom wall 112 are arranged to 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 the container 12. Specifically, the side wall 111 includes a side wall body 1111 and a connecting wall 1112. The side wall body 1111 is generally conical, and the outer diameter of the top end is smaller than the outer diameter of the bottom end. The connecting wall 1112 is generally cylindrical, integrally formed with the bottom wall 112, embedded in the bottom end of the side wall body 1111, and detachably connected to the side wall body 1111. During the manufacturing process, the side wall body 1111 is a part, and the connecting wall 1112 and the bottom wall 112 are a part. Once assembled, the connecting wall 1112 is fixedly connected to the side wall body 1111, and together they form the side wall 111. The removable bottom wall 112 facilitates the assembly of the container 12 into the first cavity 113. The container 12 is used to hold cooking ingredients. The container 12 defines a second cavity 121 with an open top, which contains the cooking ingredients. The user can add or remove cooking ingredients through the top opening of the container 12, and can also clean the interior of the container 12 through the opening.

[0050] The container 12 is rotatably connected to the bottom wall 112 of the container housing 11 via a transmission assembly 14 so as to be rotatable about its own axis. The transmission assembly 14 includes a cooking shaft 141 , a bearing 142 , and two bearings 143 .

[0051] A bearing hole 112c is provided in the center of the bottom wall 112. A downwardly protruding bearing seat 123 is provided in the center of the bottom of the container 12, and a bearing hole 1231 is provided in the bearing seat 123 that passes through the bottom of the container 12. The bearing seat 123 of the container 12 is inserted into the bearing hole 112c and is rotatably connected to the bottom wall 112 through the bearing 142. The cooking shaft 141 is inserted into the bearing hole 1231 and is rotatably connected to the bearing seat 123 through the bearing 143. The upper end of the cooking shaft 141 extends into the container 12 and is connected to the knife assembly 13. Both the bearing 142 and the bearing 143 are one-way bearings. A one-way bearing is a bearing that can be rotatably connected in one direction and locked in the opposite direction. In this embodiment, when the cooking shaft 141 rotates, one of the bearings 142 and 143 is in a rotatably connected state, and the other is in a locked state. When the cooking shaft 141 rotates forward, the bearing 142 is locked and the bearing 143 is in a rotationally connected state. The cooking shaft 141 only drives the blade assembly 13 to rotate. In this case, the food processor performs a crushing operation, processing the cooking ingredients to produce a slurry. When the cooking shaft 141 rotates backward, the bearing 142 is in a rotationally connected state and the bearing 143 is locked. The cooking shaft 141 simultaneously drives the blade assembly 13 and the container 12 to rotate. In this case, the food processor performs a centrifugal operation on the slurry. By controlling the rotation direction of the cooking shaft 141, the food processor can selectively perform a crushing operation or a centrifugal operation. When the rotation speed of the container 12 reaches a predetermined speed, the slurry flows toward the inner wall of the container 12 under the action of centrifugal force and contacts the inner wall of the container 12. At least a portion of the residue (i.e., solid particles such as food residue in the slurry) adheres to the inner wall of the container 12, and the slurry (i.e., the highly fluid liquid in the slurry) flows back to the bottom of the container 12, thereby achieving centrifugal separation of the slurry.

[0052] The blade assembly 13 is positioned within the second cavity 121 and at the top of the cooking shaft 141. Driven by the cooking shaft 141, it rotates to crush the cooking ingredients, producing a slurry. The blade assembly 13 includes a cutting blade 131 and a grinding blade 132. The cutting blade 131 is used to cut the cooking ingredients. Grinding teeth 122 are located at the bottom of the container 12, and the grinding blade 132 cooperates with the grinding teeth 122 to grind the cut cooking ingredients.

[0053] The cup cover 15 is detachably mounted on the top of the container shell 11 and the container 12. The cup cover 15 includes an outer cover 151, a bearing seat 152, an inner cover 153, a hollow column 154 and a bearing 155. The outer cover 151 is snap-connected to the container shell 11 to seal the top opening of the container shell 11. The 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 fixed relative to the container 12 by friction and cannot rotate relative to the container 12. The hollow column 154 is fixed in the center of the inner cover 153 and is rotatably connected to the bearing seat 152 through a bearing 155. The hollow column 154 connects 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 bearing 155 is a bidirectional bearing. Due to the presence of bearing 155, the inner lid 153 can rotate with the container 12 during centrifugal operation without affecting the rotation of the container 12. Furthermore, because the inner lid 153 and outer lid 151 are inseparable, the container 12 and the container housing 11 can be opened or closed simultaneously. The cup lid 15 prevents liquid from splashing during operation of the food processor. In this embodiment, the cup lid 15 is not required.

[0054] Figure 6 This is a cross-sectional view of a food processor. Figure 7 and Figure 8 They are respectively a three-dimensional structural schematic diagram and an exploded diagram of the main body 20 of the food processor. Figure 9 and Figure 10 They are respectively a three-dimensional structural diagram and an exploded diagram of the base 21 in the main body 20 of the food processor. Figure 9 The lower shell 2112, the mounting bracket 213 and the cover 214 are omitted. Figures 6 to 10As shown, the main body 20 includes a base 21, a heating component 22 and a main unit. The main unit includes a first drive component 23 and a second drive component 24. Among them, the base 21 includes a body shell 211, a locking ring 212, a mounting bracket 213, a cover 214, a transmission member 215 and a knob 216. The body shell 211 is the main structure of the base 21. The body shell 211 includes an upper shell 2111, a lower shell 2112 and a mounting seat 2113. The upper shell 2111 and the lower shell 2112 are detachably connected. The mounting seat 2113 is accommodated in the cavity formed by the upper shell 2111 and the lower shell 2112, and is detachably connected to the upper shell 2111. When assembling the first and second drive assemblies 23 and 24 to the base 21, they can first be assembled to the mounting base 2113, then the mounting base 2113 can be assembled to the upper housing 2111, and finally the lower housing 2112 can be assembled to the upper housing 2111. Compared to designing the main housing 211 as a single piece, this makes assembly of the first and second drive assemblies 23 and 24 easier. An annular guide groove 2111a is provided on the surface of the main housing 2111. Specifically, the top surface of the upper housing 2111 is provided with the annular guide groove 2111a. The annular guide groove 2111a is circular. A third stopper 2111b is provided within the annular guide groove 2111a. Multiple third stoppers 2111b are provided, spaced apart in the annular guide groove 2111a along its extension direction. The locking ring 212 is rotatably mounted on the housing 211 about its own axis. Specifically, the locking ring 212 includes an annular locking body 2121, four fourth limiting portions 2122, and four snap-fit ​​portions 2123. The four fourth limiting portions 2122 are disposed on the bottom surface of the locking body 2121 and spaced apart along the circumference of the locking body 2121. At least a portion of each fourth limiting portion 2122 is inserted into the annular guide groove 2111a, allowing the locking ring 212 to rotate about its own axis under the guidance of the annular guide groove 2111a until the third limiting portion 2111b and the fourth limiting portion 2122 are mutually restrained. Two adjacent third limiting portions 2111b define the two extreme rotational positions of the locking ring 212. The four snap-fit ​​portions 2123 are disposed on the top surface of the locking body 2121 and spaced apart along the circumference of the locking body 2121. Mounting bracket 213 is fixed to body housing 211. Specifically, mounting bracket 213 is fixed to upper housing 2111. Mounting bracket 213 has an annular protrusion 2131. Annular protrusion 2131 is sleeved onto locking ring 212. A first stopper 2133 is provided on the outer side of annular protrusion 2131. Four transverse second through-holes 2132 are formed on the side of annular protrusion 2131. These four transverse second through-holes 2132 correspond to the four latching portions 2123.The buckle portion 2123 of the locking ring 212 passes through the corresponding second through hole 2132 on the annular protrusion 2131 and is exposed on the annular protrusion 2131. The shape of the cover 214 matches the mounting bracket 213 and covers the mounting bracket 213. When the cup body 10 is placed on the main body 20, the cover 214 is placed between the cup body 10 and the main body 20. The cover 214 can be made of a heat-insulating material. Since the heating component 22 described below is arranged on the top of the base 21, the cover 214 can prevent the surface temperature of the base 21 from being too high. The cover 214 can also be made of an elastic material to reduce the vibration between the cup body 10 and the main body 20. The cover 214 is not required. The cover 214 can also be an integral structure with the mounting bracket 213. The transmission member 215 is rotatably arranged on the top of the upper shell 2111 and is located on the outside of the locking ring 212, engaging with the locking ring 212. When the transmission member 215 rotates, the transmission member 215 can drive the locking ring 212 to rotate. The knob 216 is plugged into and matched with the transmission member 215. When the user turns the knob 216, the transmission member 215 can be driven to rotate, thereby driving the locking ring 212 to rotate.

[0055] The process of assembling the base 21 is as follows: first, assemble the locking ring 212 and the transmission member 215 to the top of the fuselage shell 211 respectively; then fix the mounting bracket 213 to the top of the fuselage shell 211; then cover the mounting bracket 213 with the cover 214, and then plug the knob 216 into the transmission member 215.

[0056] Please also refer to Figure 3 and Figure 6The sidewall 111 of the container shell 11 is removably mounted on the base 21, thereby indirectly allowing the container 12 to be removably mounted on the base 21. Specifically, a latching portion 1112a is provided at the bottom of the sidewall 111 of the container shell 11, which mates with a latching portion 2123. The locking ring 212 can be rotated to different positions to achieve a locked or separated state between the latching portion 2123 and the latching portion 1112a. Specifically, the latching portion 2123 engages or disengages with the latching portion 1112a via a portion exposed by an annular protrusion 2131. The bottom wall 112 of the container shell 11 is higher than the bottom end of the sidewall 111, allowing the container shell 11 to cover the mounting bracket 213. The bottom end of the sidewall 111 of the container shell 11 is sleeved over the annular protrusion 2131. Of course, if a cover 214 is provided, it is also interposed between the container shell 11 and the mounting bracket 213. A second stopper 1112b is provided on the inner side of the bottom end of the side wall 111. The first stopper 2133 and the second stopper 1112b engage to restrict the rotation of the housing 11. In this embodiment, the first stopper 2133 is convexly disposed on the outer wall of the annular protrusion 2131, while the second stopper 1112b is concavely disposed on the inner wall of the side wall 111. In other embodiments, the first stopper 2133 may be concavely disposed on the outer wall of the annular protrusion 2131, while the second stopper 1112b is convexly disposed on the inner wall of the side wall 111.

[0057] The process of assembling the cup body 10 to the main body 20 is as follows: after aligning the second limiting portion 1112b with the first limiting portion 2133, the cup body 10 is placed on top of the main body 20; the user turns the knob 216, which drives the locking ring 212 to rotate via the transmission member 215, so that the locking portion 2123 and the locking portion 1112a are in a locked state. The process of removing the cup body 10 from the main body 20 is as follows: the user turns the knob 216 in the opposite direction, which drives the locking ring 212 to rotate via the transmission member 215, so that the locking portion 2123 and the locking portion 1112a are in a separated state; and the cup body 10 is lifted upward to separate the cup body 10 from the main body 20.

[0058] The assembled base 21 forms a cavity 21a with an open top. Cavity 21a is used to accommodate a heating assembly 22, a first drive assembly 23, and a second drive assembly 24. The heating assembly 22 is mounted on the base 21 and is capable of rising toward the bottom of the container 12 or descending away from the bottom of the container 12 when the container 12 is removably mounted on the base 21. Specifically, the heating assembly 22 is positioned below the container 12, with at least a portion disposed within the cavity 21a of the base 21. The heating assembly 22 is movably connected to the base 21 to enable vertical movement relative to the base 21. Figure 11 yes Figure 6 AA section view. Figure 6 and Figure 11As shown, to enable the heating assembly 22 to move along a predetermined path, the base 21 has a guide portion 217, and the heating assembly 22 has a guide portion 2221a. The guide portion 2221a slidably engages with the guide portion 217 in the direction of movement of the heating assembly 22. Specifically, the guide portion 217 and the guide portion 2221a are respectively disposed on a pair of opposing surfaces of the base 21 and the heating assembly 22. The guide portion 217 is a column extending in the direction of movement of the heating assembly 22, while the guide portion 2221a is a groove extending in the direction of movement of the heating assembly 22. In this embodiment, the guide portion 217 is disposed on the wall of the cavity 21a of the base 21. The guide portion 2221a is disposed on the outer edge of the heating assembly 22. Of course, in other embodiments, the positions of the guide portion 217 and the guide portion 2221a can be interchanged, that is, the guide portion 217 is disposed on the heating assembly 22, and the guide portion 2221a is disposed on the base 21.

[0059] The heating element 22 can also generate heat by itself, so as to heat the container 12 when it is close to the bottom of the container 12, thereby heating the cooking materials in the container 12. Furthermore, when the heating element 22 contacts the bottom of the container 12, it heats the container 12 to improve the heat transfer efficiency.

[0060] Figure 12 3D schematic diagram of the heating component 22 in the food processor. Figure 5 and Figure 12 As shown, in order to enable the heating component 22 to heat the bottom of the container 12, a first through-hole 112a is provided on the bottom wall 112, so that at least a portion of the heating component 22 can extend into the first cavity 113 and fit against the bottom of the container 12. Specifically, there are a plurality of first through-holes 112a on the bottom wall 112. The upper surface of the heating component 22 has heating protrusions 2211a corresponding one-to-one to the first through-holes 112a. Avoidance grooves 2211b that match the shape of the bottom wall 112 are formed between the heating protrusions 2211a. When the heating component 22 approaches the bottom of the container 12, the heating protrusions 2211a can pass through the first through-holes 112a on the bottom wall 112, and the bottom wall 112 is at least partially accommodated in the avoidance grooves 2211b. In this embodiment, the bottom wall 112 has three spokes 112b distributed radially. A first through-hole 112a is formed between two adjacent spokes 112b. Each first through-hole 112a is generally fan-shaped. The shape and size of the heating protrusions 2211a match those of the first through-holes 112a. When the heating assembly 22 approaches the bottom of the container 12, the spokes 112b are accommodated in the avoidance grooves 2211b between adjacent heating protrusions 2211a. The provision of multiple first through-holes 112a on the bottom wall 112 ensures that the heating assembly 22 maximizes contact with the bottom of the container 12, thereby improving heating efficiency.

[0061] Figure 13It is a three-dimensional structural diagram of the heating component 22 in the food processor from another perspective. Figure 14 It is an exploded view of the heating component 22 in the food processor. Figure 15 2 is an exploded view of the heating unit 221 in the heating assembly 22 of the food processor. Figures 13 to 15 As shown, the heating assembly 22 includes a heating unit 221 , a support member 222 , five elastic members 223 and five fasteners 224 .

[0062] The heating unit 221 is located on the side of the support member 222 facing the container 12. The heating unit 221 itself is capable of generating heat. The heating unit 221 comprises a heat transfer body 2211, nine heating elements 2212, a heat insulator 2213, a locking element 2214, and a sensor 2215. The heat transfer body 2211 is thermally conductive and made of a thermally conductive material, such as an aluminum alloy. The aforementioned heating protrusion 2211a is located on the side of the heat transfer body 2211 facing the container 12. The heat transfer body 2211 is generally annular in shape. Five guide posts 2211c are also protruding from the heat transfer body 2211. The five guide posts 2211c extend toward the support member 222 and are spaced apart around the axis of the heat transfer body 2211. The heating elements 2212 are thermally coupled to the heat transfer body 2211 and are capable of generating heat when powered. The heating elements 2212 may be heat pipes inserted into the heat transfer body 2211. The heat pipes may be conventionally selected. Nine heating elements 2212 are evenly distributed on the heat transfer body 2211 around the axis of the heat transfer body 2211 to ensure a uniform temperature on the heat transfer body 2211. A heat insulating member 2213 is sleeved on the outer periphery of the heat transfer body 2211. The heat insulating member 2213 is made of a heat-insulating material to prevent heat loss from the heat transfer body 2211. A locking member 2214 is sleeved on the outside of the heat insulating member 2213 and is detachably connected to the heat transfer body 2211 to stably secure the heat insulating member 2213 to the heat transfer body 2211. The heat transfer body 2211 has a first snap-fit ​​portion 2211d. The inner peripheral side wall of the locking member 2214 has a second snap-fit ​​portion 2214b. The first snap-fit ​​portion 2211d and the second snap-fit ​​portion 2214b snap-fit ​​together. The locking member 2214 is generally annular in shape, with three notches 2214a provided on its outer periphery. The three notches 2214a are spaced apart around the locking member 2214. The sensor 2215 is provided on the heat transfer body 2211 for detecting the temperature of the heat transfer body 2211 or for detecting the temperature of the container 12 when in contact with the container 12.

[0063] The process of assembling the heating unit 221 is as follows: assemble the heating element 2212 and the sensor 2215 to the heat transfer body 2211 ; then assemble the heat insulation element 2213 to the heat transfer body 2211 ; and then assemble the locking element 2214 to the heat transfer body 2211 .

[0064] The support member 222 includes a support body 2221 and four support blocks 2222. The support body 2221 is generally in the shape of a hollow disk, and the outer periphery thereof is provided with three guide portions 2221a. After the heating assembly 22 is assembled, the three notches 2214a of the locking member 2214 correspond to the three guide portions 2221a one by one. The notches 2214a are used to avoid the guide portion 217 (see Figure 11 ). The support body 2221 is also provided with five guide holes 2221b. The five guide holes 2221b correspond one to one with the five guide posts 2211c. After the heating component 22 is assembled, each guide post 2211c passes through the support member 222 through the corresponding guide hole 2221b. The guide post 2211c slides into the guide hole 2221b to guide the heating unit 221 to move relative to the support member 222. The four support blocks 2222 are located on the side of the support body 2221 facing away from the heating unit 221, and each support block 2222 is used to conflict with the first surface 2331 of the transmission member 233 described below.

[0065] The heating unit 221 is floatably mounted on the support member 222 in the direction in which the guide posts 2211c extend. Specifically, the opposite ends of each elastic member 223 are elastically coupled to the heating unit 221 and the support member 222. Specifically, the five elastic members 223 correspond one to each of the five guide posts 2211c. Each elastic member 223 is sleeved around its corresponding guide post 2211c, with its opposite ends elastically abutting / connected to the heat transfer body 2211 and the support body 2221. The elastic members 223 may be springs.

[0066] The fasteners 224 are connected to the ends of the guide posts 2211c and are used to interfere with the support member 222. Specifically, there are five fasteners 224 corresponding to the five guide posts 2211c. Each fastener 224 is located on the side of the support body 2221 facing away from the heating unit 221 and is connected to the end of the corresponding guide post 2211c. The fasteners 224 can be nuts that are threadedly connected to the guide posts 2211c.

[0067] The process of assembling the heating component 22 is as follows: first, the five elastic members 223 are respectively mounted on the five guide posts 2211c of the heating unit 221; then, the support member 222 is assembled onto the heating unit 221 so that the five guide posts 2211c pass through the five guide holes 2221b; and the five fasteners 224 are respectively connected to the ends of the five guide posts 2211c.

[0068] In this embodiment, when the heating assembly 22 is not subjected to external forces, the elastic member 223 is in a compressed state. Under the elastic force of the elastic member 223, the fastener 224 contacts the support body 2221. As a result, the heating assembly 22 is compact, the relative positions of the various components within the heating assembly 22 are stable, and the heating unit 221 and the support member 222 do not move relative to each other (when not subjected to external forces). If the fastener 224 is a nut, the degree of compression of the elastic member 223 can be adjusted by tightening or loosening the nut.

[0069] Driven by the first drive assembly 23, the support member 222 moves toward the container 12. At this time, the support member 222 drives the heating unit 221 to move toward the container 12 through the elastic member 223. After the heating unit 221 contacts the container 12 and stops moving, the support member 222 will still move slightly toward the container 12, so that the elastic member 223 is further compressed, and the elastic force toward the container 12 is applied to the heating unit 221, thereby making the heating unit 221 close to the container 12. Even if the container 12 moves slightly in some cases, the heating unit 221 can always be close to the container 12 and stably heat the container 12. Through the above-mentioned structural design, the heating component 22 can elastically press against the container 12 when it contacts the container 12, so that the heating component 22 better fits the container 12 and improves the heat transfer efficiency.

[0070] The heating unit 221 and the support member 222 are both annular, and the hollow areas of the heating unit 221 and the support member 222 have an overlapping area, which is used to avoid the second drive assembly 24 of the food processor. For details, see the introduction of the second drive assembly 24 below.

[0071] like Figure 6 and Figure 7As shown, the first drive assembly 23 is mounted on the base 21 and is capable of driving the heating assembly 22 upward or downward. Specifically, the first drive assembly 23 is mounted on the mounting base 2113 and positioned below the heating assembly 22. The first drive assembly 23 includes a transmission member 233, a gear 232, and a first motor 231. The transmission member 233 is rotatably mounted on the mounting base 2113 and is capable of rotating about an axis L1. The transmission member 233 has a first surface 2331. The first surface 2331 is located outside the axis L1, extending around the axis L1 and extending in the direction of the axis L1 to form a helical surface. The gear 232 is rotatably mounted on the mounting base 2113 and meshes with the transmission member 233. The first motor 231 is mounted on the mounting base 2113, and its output shaft is connected to the gear 232. The first motor 231 can rotate forward and reverse to drive the transmission member 233 to rotate in either a first direction D1 or a 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 oblique to the axis L1, converting the rotational motion of the transmission member 233 into linear motion of the heating assembly 22. When the transmission member 233 rotates in the first direction D1, the heating assembly 22 moves downward under the action of gravity, away from the container 12. When the transmission member 233 rotates in the second direction D2, the heating assembly 22 moves upward under the push of the first surface 2331, approaching until it contacts the container 12. The number of first surfaces 2331 can be multiple, and the multiple first surfaces 2331 are spaced apart around the axis L1. This ensures that the force applied to the heating assembly 22 is more uniform, preventing it from getting stuck with the base 21 during the ascent process.

[0072] The second drive assembly 24 is mounted on the mounting base 2113, below the bottom wall 112 of the container housing 11. The heating assembly 22 has a clearance hole 225 extending vertically therethrough. The driving end of the second drive assembly 24 passes through the clearance hole 225 and is removably connected to the lower end of the cooking shaft 141. The second drive assembly 24 is used to drive the container 12 and / or the knife assembly 13 to rotate. Specifically, 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 mounted on the mounting base 2113. The second connector 242 is fixed to the output shaft of the second motor 241. When the cup body 10 is mounted on the base 21, the first connector 144 and the second connector 242 engage and form a coupling, connecting the cooking shaft 141 to the output shaft of the second motor 241, allowing the second motor 241 to 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. When the food processor is performing a centrifugal operation, if the heating assembly 22 comes into contact with the bottom of the container 12, it will affect the rotation of the container 12. To this end, the first drive assembly 23 is configured to drive the heating assembly 22 toward and into contact with the container 12 during at least a portion of the time when the container 12 is stopped from rotating, and to drive the heating assembly 22 away from the container 12 before the container 12 rotates. For example, while the second drive assembly 24 is operating to rotate the container 12, the user cannot select a heating mode. Alternatively, the first drive assembly 23 can be pre-set to drive the heating assembly 22 away from the container 12 after the heating is complete. Alternatively, when the user selects the centrifugal mode, the food processor's controller (not shown) can determine whether the heating assembly 22 is separated from the container 12. If so, it controls the second drive assembly 24 to rotate the container 12; otherwise, it controls the first drive assembly 23 to separate the heating assembly 22 from the container 12.

[0073] Beneficial effects:

[0074] In this embodiment, the heating component 22 includes a support member 222 and a heating unit 221. The heating unit 221 is provided on the support member 222, and the support member 222 can approach or move away from the container 12 of the food processor under the drive of the main unit of the food processor. When the support member 222 approaches the container 12, the heating unit 221 contacts the container 12 and heats the container 12. When the food processor is in a non-heating state, the heating component 22 can be kept away from the container 12, and even if liquid flows down the outer wall of the container 12, it will not flow directly onto the heating component 22. The present application can reduce the probability of the heating component 22 being stained with liquid, thereby reducing the risk of short circuit or damage to the heating component 22.

[0075] Since the container 12 can rotate about its own axis, the heating assembly 22 can approach or move away from the container 12. The first driving assembly 23 can drive the heating assembly 22 away from the container 12 before the container 12 rotates, and drive the heating assembly 22 to approach and contact the container 12 during at least a portion of the period when the container 12 stops rotating. In this way, the heating assembly 22 can be prevented from affecting the rotation of the container 12.

[0076] The heating unit 221 has a guide post 2211c that extends toward one side of the support member 222. The support member 222 is provided with a guide hole 2221b. The guide post 2211c passes through the support member 222 through the guide hole 2221b. The heating unit 221 is floatably disposed on the support member 222 in the direction in which the guide post 221c extends. This allows the heating unit 221 to elastically contact the container 12, thereby better fitting the container 12 and improving heat transfer efficiency. Furthermore, guided by the guide post 221c, the heating unit 221 can move more smoothly relative to the support member 222.

[0077] The heating assembly 22 further includes a fastener 224. The fastener 224 is connected to the end of the guide column 2211c and is used to interfere with the support member 222. As a result, the overall structure of the heating assembly 22 is more compact.

[0078] The fastener 224 is screwed to the guide post 2211 c . Thus, the elastic force of the elastic member 223 can be adjusted by the fastener 224 .

[0084] The second cooking shaft 33 is inserted into the third bearing hole 324 and is rotatably connected to the container 32 via the bearing 34. The bearing 34 is a bidirectional bearing, allowing the second cooking shaft 33 to rotate forward and reverse relative to the container 32. Specifically, the second cooking shaft 33 includes a first shaft 331 and a first connector 332. The first shaft 331 is inserted into the bearing hole 324 and is rotatably connected to the container 32 via the bearing 34. The top end of the first shaft 331 is accommodated in the second cavity 321. The first connector 332 is fixed to the bottom end of the first 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, allowing the first connector 332 to rotate with the first shaft 331. To prevent leakage from the container 32, a sealing material is placed between the first shaft 331 and the container.

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

[0086] The cup cover 35 is detachably mounted on the top of the container shell 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 shell 31 to seal the top opening of the container shell 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 fixed relative to the container 32 by friction and cannot rotate relative to the container 32.

[0088] The container shell 31 is placed on the base 41 , and the base 41 is located at the open bottom portion of the container shell 31 to support the container 32 .

[0089] The first driving assembly 43 can be described in the first embodiment and will not be described again here.

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

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

[0092] The second bearing seat 46 is hollow and cylindrical, with a larger outer diameter at its upper end than at 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 via a first bearing 471.

[0093] The first cooking 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 shaft 48 includes a second shaft 481 and a second connector 482. The bottom end of the second 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 fixed to the top of the second shaft 481 and can be plugged and matched with the first connector 332 in the upper and lower directions to form a coupling to connect the first shaft 331 and the second shaft 481. The first bearing 471 and the second bearing 472 are both one-way bearings. When one of the first bearing 471 and the second bearing 472 is rotatably connected, the other is locked.

[0094] Plug 49 is generally cylindrical and fits over the top of second bearing seat 46. The outer shape of plug 49 matches the inner shape of slot 322, allowing plug 49 to engage with slot 322 vertically. The connection between plug 49 and slot 322 is similar to the connection between first connector 332 and second connector 482. Plug 49 can be separate from or integral with second bearing seat 46.

[0095] Figure 21 It is a three-dimensional structural diagram of the heating component 42 in the second embodiment of the food processor of the present application. Figure 22 It is a cross-sectional view of the heating component 42 in the second embodiment of the food processor of the present application. Figure 23 This is an exploded view of the heating component 42 in the second embodiment of the food processor of the present application. Figure 24 It is an exploded view of the heating unit 421 in the heating component 42 in the second embodiment of the food processor of the present application.

[0096] like Figures 21 to 24 As shown, the heating assembly 42 includes a heating unit 421 , a support member 422 , five elastic members 423 and five fasteners 424 .

[0097] The heating unit 421 includes a heat transfer body 4211 , a heating element 4212 , a cover 4213 , a sensor 4214 and a sensor 4215 .

[0098] The heat transfer body 4211 is thermally conductive and is made of a thermally conductive material, such as aluminum alloy. The side of the heat transfer body 4211 facing the container 12 is a flat surface. The heating element 4212 is thermally coupled to the heat transfer body 4211 and can generate heat when powered on. The heating element 4212 can be a heating tube. The heating tube can be optionally of the existing technology. The heating element 4212 is annular and is arranged outside the axis of the heat transfer body 4211. The cover plate 4213 is covered on the heating element 4212 and is fixedly connected to the heat transfer body 4211. The cover plate 4213 and the heat transfer body 4211 can be integrally formed or separately formed. The sensor 4214 is provided on the heat transfer body 4211 for detecting the temperature of the heat transfer body 4211. The sensor 4215 is provided on the heat transfer body 4211 for detecting the temperature of the container 32 when in contact with the container 32. The part of the heating unit 421 not introduced can be parameter embodiment one.

[0099] Before cooking, align the slot 322 at the bottom of the container 32 with the plug 49 on the main body 40, so that the slot 322 and plug 49 engage vertically. Then, place the container 32 on top of the main body 40. As the slot 322 engages the plug 49, the second cooking shaft 33 and the first cooking shaft 48 automatically engage. Next, place the container housing 31 on top of the main body 40, fitting over the container 32. After adding cooking ingredients to the container 32, place the cup lid 35 over the container housing 31 and container 32. After cooking is complete, remove the cup lid 37, container housing 31, and container 32 in order to transfer the cooking ingredients from the container 32 and clean the container 32.

[0100] The food processor can heat the cooking ingredients. Specifically, the first drive assembly 43 is activated to drive the heating assembly 42 upward until the heating assembly 42 contacts the bottom of the container 32. After the heating assembly 42 heats the container 32 for a predetermined period of time, the first drive assembly 43 is activated to drive the heating assembly 42 downward, away from the container 32.

[0101] The food processor can grind food ingredients. Specifically, the output shaft of the motor 44 rotates in a first direction. At this time, the second bearing 472 is in a rotationally connected state, while the first bearing 471 is locked. The container 32 cannot rotate. The motor 44 drives the blade assembly 36 via the first and second cooking shafts 48 and 33 to rotate, cutting and grinding the food ingredients. During the grinding process, the non-rotatable container 32 can improve the grinding effect.

[0102] The food processor can centrifuge the food. The output shaft of the motor 44 rotates in a second direction opposite to the first direction. At this time, the first bearing 471 is in a rotationally connected state, and the second bearing 472 is in a locked state. The motor 44 drives the knife assembly 36 and the container 32 to rotate together via the first and second cooking shafts 48 and 33, thereby centrifuging the food.

[0103] Since the container 32 can rotate about its own axis, the heating assembly 42 can approach or move away from the container 32. The first driving assembly 43 can drive the heating assembly 42 away from the container 32 before the container 32 rotates, and drive the heating assembly 42 to approach and contact the container 32 during at least a portion of the period when the container 32 stops rotating. In this way, the heating assembly 42 can be prevented from affecting the rotation of the container 32.

[0104] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
