Description

Technical Field

[0001] The present application relates to the technical field of small household appliances, and in particular to a heating plate assembly and a food processor. Background Art

[0002] The food processor comprises a main machine and a mixing cup assembly. The mixing cup assembly comprises a mixing cup and a heating plate assembly located at the bottom of the mixing cup. The heating plate assembly and the mixing cup enclose a food processing space, and the heating element of the heating plate assembly is used to heat food in the food processing space.

[0003] During the heating of the heating element and the rotation of the blade of the stirring knife assembly, foam will be generated in the food cavity formed by the plate body of the heating plate and the stirring cup. Therefore, how to reduce the foam is a problem that must be solved. Utility Model Content

[0004] The purpose of the present application is to disclose a heating plate assembly and a food processor. The heating plate assembly can achieve a good defoaming effect of the food processor.

[0005] The present application discloses a heating plate assembly. The heating plate assembly includes a plate body and a stirring blade assembly. The plate body includes a stirring chamber surrounded by a plate bottom wall and a plate side wall, and the width of the stirring chamber along the horizontal direction decreases toward the direction of the plate bottom wall. The stirring blade assembly is arranged on the plate bottom wall, and includes a driving shaft and a blade assembly, and the blade assembly includes a blade and a blade mounting member. The driving shaft rotates relative to the plate body; the blade is mounted on the driving shaft by the blade mounting member. In the vertical direction, the highest blade tip of at least one of the second blades is lower than the top end of the blade mounting member.

[0006] As set up as above, the rotation of the blade assembly of the stirring blade assembly will generate a vortex, and this vortex causes the foam generated by the blade assembly in the previous stage (such as the high-speed rotation stage) to move toward the center of the vortex. Since in the vertical direction, the highest tip of the blade is lower than the top of the blade mounting member, this distance relationship ensures that when the blade assembly rotates to generate the vortex, the space between the blade and the blade mounting member becomes solid because it is filled with liquid. Therefore, based on the Coanda effect, the blade mounting member drains the liquid stirred by the blade assembly to allow the liquid to enter the stirring chamber, thereby preventing the foam generated in the high-speed operation stage of the blade assembly from entering the stirring chamber. Combined with the fact that the width of the stirring chamber in the horizontal direction decreases toward the bottom wall of the plate, and the drained liquid is stirred by the first blade to enhance the fluidity of the liquid, therefore, the faster flow of the liquid in the stirring chamber will drive the faster flow of the liquid outside the stirring chamber, and then, the flowing liquid and the foam in the center of the vortex are mixed faster and better to play a defoaming role. Finally, the defoaming effect of the heating plate assembly of the present application is good. In addition, in some cases, it is not easy to generate foam when the knife assembly rotates at a low speed (which can be considered as a kind of defoaming). This method combined with the aforementioned structure further improves the defoaming effect of the heating plate assembly of the present application.

[0007] In some embodiments, the blade includes at least one first blade extending into the stirring chamber and at least one second blade extending out of the stirring chamber.

[0008] As described above, the second blade extends out of the stirring chamber, so that the second blade can stir the liquid outside the stirring chamber, and the first blade stirs the liquid in the stirring chamber. Combined with the drainage effect of the blade mounting member, the fluidity of the liquid is better, so that the liquid is better and faster mixed with the foam, and the defoaming effect is better. When this embodiment is combined with the width of the stirring chamber in the horizontal direction decreasing toward the bottom wall of the plate, the fluidity of the liquid is better, and then, the liquid and the foam are better mixed, and the defoaming effect is better.

[0009] In some embodiments, the disk sidewall includes an inner surface of the disk sidewall, and the inner surface of the disk sidewall extends outward in an arc shape relative to the disk bottom wall, so that the width of the stirring chamber in the horizontal direction decreases toward the disk bottom wall.

[0010] As set up above, since the side wall of the disk is arc-shaped, the arc-shaped side wall of the disk will guide the fluid to form a more dynamic and complex flow pattern during the stirring process, generating more complex and irregular vortices. At the same time, the vortex energy can be distributed more unevenly in the stirring area, resulting in better fluidity of the fluid (such as faster flow rate); compared with the more stable flow of a flat disk, the mixing property is better and the defoaming effect is also better.

[0011] In some embodiments, the heating disk assembly includes a heating element, and the heating element is attached to the side wall of the disk to form a contact surface. The blade includes at least one first blade extending into the stirring chamber. In the vertical direction, the tip of at least one first blade is located between the highest point and the lowest point of the contact surface.

[0012] As described above, since the heating element is arranged on the side wall of the dish to form a contact surface, the tip of at least one first blade is located between the highest point and the lowest point of the contact surface. On the one hand, the food is usually located on the bottom wall of the dish. After the side wall of the dish is heated, the heat is transferred to the bottom wall of the dish to heat the food. After the heating element is arranged on the side wall of the dish, it is far away from the bottom wall of the dish. In this way, it is not easy to burn the bottom wall of the dish. Moreover, the rotation of the first blade will also make the food in the contact surface area fluid, and these foods will not stick to the side wall of the dish, thereby avoiding the side wall of the dish from being burned. In summary, the heating element is arranged on the side wall of the dish and matched with the positional relationship between the contact surface and the tip of the first blade, which can avoid the dish body from being burned. Of course, in the case where the contact surface is a curved surface, the area of ​​the curved surface is larger, the heat is not concentrated, and it is more possible to avoid the dish body from being burned.

[0013] In some embodiments, the height difference between the top end of the blade mount and the blade tip is d, 0mm<d≤25mm.

[0014] As configured above, since 3mm≤d≤25mm, the blade mounting member has a better drainage effect and enables liquid and foam to be mixed faster and better, thereby achieving a better defoaming effect.

[0015] In some embodiments, the blade mount meets at least one of the following characteristics:

[0016] a) In the vertical direction, the distance between the top of the blade mounting member and the bottom wall of the disk is H, 25mm≤H≤50mm; as set above, since 25mm≤H≤50mm, the drainage effect of the blade mounting member is better, and the foam is prevented from entering the stirring chamber. Ultimately, the heating disk assembly has a better defoaming effect.

[0017] b) In the vertical direction, the distance between the top of the blade mounting member and the root of the blade is h, 15mm≤h≤35mm. As described above, since 15mm≤h≤35mm, it is not only ensured that the blade mounting member has a sufficient length for better drainage, but also provides a gripping portion of sufficient length to facilitate the placement of the knife assembly or the mixing knife assembly. In the embodiment in which the knife assembly and the drive shaft are detachably assembled, the gripping portion facilitates the disassembly and assembly of the knife assembly.

[0018] c) The blade mounting member is cylindrical. As described above, since the blade mounting member is cylindrical, the curved surface of the cylinder is more convenient for drainage, thereby achieving the defoaming effect and facilitating gripping.

[0019] In some embodiments, the drive shaft is assembled to the bottom wall of the disk via a bearing seat, and the knife assembly is detachably assembled with the drive shaft.

[0020] As set up above, since the knife assembly and the drive shaft are detachably assembled, the knife assembly can be disassembled for cleaning, which is convenient. The heating element assembly is clean and the user experience is good.

[0021] In some embodiments, the knife assembly satisfies at least one of the following conditions:

[0022] a) The blade mounting component includes a socket and a mounting hole located at the bottom of the socket, and the mounting hole is circular; the top end of the drive shaft includes a cylindrical mounting portion, the drive shaft is inserted into the socket, and the mounting portion is concentric with the mounting hole; the mounting portion is inserted into the mounting hole; as set up as above, because the mounting portion is concentric with the mounting hole, after the drive shaft is inserted into the socket, the concentricity of the knife assembly and the drive shaft can be calibrated, otherwise, the center of the mounting portion and the center of the mounting hole will not coincide.

[0023] b) The drive shaft includes an assembly section, the assembly section includes a plurality of side edges extending in the up-down direction, the plurality of side edges gradually deflect along the circumference of the assembly section, the blade and / or the blade mounting member is provided with a drive hole matching the assembly section, the drive hole includes a plurality of convex corners extending vertically in the up-down direction, the plurality of convex corners are respectively abutted and matched with the plurality of side edges. As set up as above, the side edges and the convex corners cooperate to apply a force to the knife assembly to prevent the knife assembly from being separated from the drive shaft. The knife assembly moves in different directions along the deflection of the side edges to achieve assembly and disassembly, and the assembly and disassembly of the knife assembly is convenient.

[0024] In a second aspect, the present application discloses a food processor. The food processor comprises a blending cup assembly and a main machine, wherein the blending cup assembly comprises any one of the aforementioned heating plate assemblies and the blending cup, wherein the heating plate assembly is located at the bottom of the blending cup, and the plate body and the blending cup form a food cavity; the main machine comprises a driving assembly, and the driving assembly drives the blade to rotate in the food cavity; the working stages of the blade include a high-speed stage and a low-speed stage, and the high-speed stage precedes the low-speed stage.

[0025] As configured above, the blending cup assembly has at least the beneficial effects of the heating plate assembly, which will not be elaborated. In particular, based on the structure of the heating plate assembly, the high-speed stage precedes the low-speed stage. In the low-speed stage, the heating plate assembly can play a defoaming role to avoid foam in the blending cup.

[0026] In some embodiments, the speed in the low speed stage is V, 500RPM≤V≤3000RPM.

[0027] As described above, the food processor has at least the beneficial effects of the heating plate assembly, which will not be described in detail. In addition, since 500RPM≤V≤3000RPM, the knife assembly is ensured to rotate at a low speed, and it is not easy to generate foam, the drainage effect of the blade mounting part, etc., thereby ensuring a good defoaming effect.

[0028] In some embodiments, along the vertical direction, the vortex formed by the blade stirring the liquid in the blending cup has a height Q relative to the bottom wall of the disk, the height between the top of the blade mount and the bottom wall of the disk is H, and 1 / 5≤H / Q≤1 / 2.

[0029] As set above, since 1 / 5≤H / Q≤1 / 2, Q can be determined to ensure that the foam moves toward the center of the vortex. In addition, H and Q in the above ratio range correspondingly limit the low-speed rotation of the knife assembly, and low-speed rotation is not easy to generate foam. Therefore, based on the above-mentioned proportional relationship and the distance relationship between the blade mounting part and the blade tip, the drainage effect of the blade mounting part and the mixing of the liquid and the foam in the center of the vortex can be ensured, thereby ensuring that the defoaming effect of the heating plate assembly is good.

[0042] See also Figure 8 and Figure 4 Combined with Fig. 9 , Fig.10 and Figure 2 , the present application discloses a heating plate assembly 10. The heating plate assembly 10 includes a plate body 1 and a stirring blade assembly 2. Of course, the heating plate assembly 10 is not limited to the method of using the heating element 3 as described later, nor is it limited to the implementation method in which the heating element 3 is arranged on the plate side wall 12, as long as the heating plate assembly 10 has a heating function. The plate body 1 includes a stirring chamber 13 surrounded by a plate bottom wall 11 and a plate side wall 12. The width of the stirring chamber 13 along the horizontal direction decreases toward the direction of the plate bottom wall 11. Figure 8 , the width w decreases in the downward direction, for example, when the stirring chamber 13 is circular, the width w is the diameter of the stirring chamber 13. How to reduce is not limited to the embodiment in which the inner surface of the disk side wall 12 is arc-shaped as described later, and the inner surface may be a plane inclined to the disk bottom wall 11. In short, it is sufficient to achieve the reduction.

[0043] See also Figure 4 and Figure 8 Combined with Fig. 9 , Fig.10Combined with Figure 2 , the stirring blade assembly 2 includes a driving shaft 21 and a blade assembly 22. The blade assembly 22 includes a blade 221 and a blade mounting member 222. The driving shaft 21 rotates relative to the bottom wall 11 of the disk, and how to rotate is not limited to being assembled to the bottom wall 11 of the disk through a bearing seat as shown in the figure. In some embodiments in which the driving assembly drives the blade 221 through magnetic force, the blade assembly 22 can be fixed to the bottom wall 11 of the disk through a fixed structure, or can be placed on the bottom wall 11 of the disk through a base and adsorbed to the bottom wall 11 through magnetic force. Regardless of the embodiment, the driving shaft 21 can rotate relative to the bottom wall 11 of the disk. The blade 221 is mounted on the driving shaft 21 by the blade mounting member 222. There is no limit to how to install it, as long as the blade 221 and the driving shaft 21 can rotate synchronously. The number of blades 221 is not limited, see Figure 6 and Figure 4 as well as Figure 3 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 In the embodiment of the present application, the blade 221 has four pieces (that is, the knife assembly 22 is a four-leaf knife), including two first blades 2211 and two second blades 2212.

[0044] See also Fig. 9 and Fig.10 , along the vertical direction (which can be understood as the direction of the rotation centerline of the drive shaft 21), the highest blade tip 2213 of the blade 221 is lower than the top of the blade mounting member 222. In the embodiment of the present application, the highest blade tip 2213 is the blade tip 2213 of the second blade 2212. Here, when the second blade 2212 has only one blade, the highest blade tip 2213 refers to the blade tip of the second blade 2212, and when the second blade 2212 has two or more blades, the highest blade tip 2213 is the highest blade tip 2213 along the vertical direction. Fig. 9 and Fig.10 The height difference between the two is shown as d.

[0045] As described above, the rotation of the blade assembly 22 of the stirring blade assembly generates a vortex, which causes the foam ( Fig. 9 and Fig.10The blade 221 moves toward the center of the vortex, and since the highest blade tip 2213 of the blade 221 is lower than the top of the blade mounting member 222 in the vertical direction, this distance relationship ensures that when the blade assembly rotates to generate the vortex, the space between the blade 221 and the blade mounting member 222 is filled with liquid and becomes solid. Therefore, based on the Coanda effect, the blade mounting member 222 drains the liquid stirred by the blade assembly 22 to allow the liquid to enter the stirring chamber 13, thereby preventing the foam generated by the high-speed operation stage of the blade assembly 22 from entering the stirring chamber 13 (compare Fig.10 and Fig. 9 It can be seen that), combined with the fact that the width of the stirring chamber 13 in the horizontal direction decreases toward the bottom wall 11 of the disk, and the liquid after drainage is stirred by the first blade 2211 to enhance the fluidity of the liquid, the faster flow of the liquid in the stirring chamber 13 will drive the faster flow of the liquid outside the stirring chamber 13, and then the flowing liquid and the foam in the center of the vortex are mixed faster and better to play a role in defoaming. Finally, the defoaming effect of the heating disk assembly 10 of the present application is good. In addition, in some cases, it is not easy to generate foam when the knife assembly 22 rotates at a low speed (which can be considered as a kind of defoaming). This method combined with the aforementioned structure further makes the defoaming effect of the heating disk assembly 10 of the present application good.

[0046] In some embodiments, the blade 221 includes at least one first blade 2211 extending into the stirring chamber 13 and at least one second blade 2212 extending out of the stirring chamber 13. In other embodiments, all blade tips of the blade 221 may be located outside the stirring chamber 13, or part of the blade 221 may be located outside the stirring chamber 13, or at least part of the root of the blade 221 assembled with the blade mounting member 222 may be located inside the stirring chamber 13, but the blade tip may extend out of the stirring chamber, etc. In short, the liquid stirred by the blade assembly 22 may enter the stirring chamber 13 under the drainage effect of the blade mounting member 222.

[0047] As described above, the second blade 2212 extends out of the stirring chamber 13, so that the second blade 2212 can stir the liquid outside the stirring chamber 13, and the first blade 2211 stirs the liquid in the stirring chamber 13, and combined with the drainage effect of the blade mounting member 222, the fluidity of the liquid is better, so that the liquid is better and faster mixed with the foam, and the defoaming effect is better. When this embodiment is combined with the width of the stirring chamber 13 in the horizontal direction being reduced toward the bottom wall 11 of the plate, the fluidity of the liquid is better, and then, the liquid and the foam are better mixed, and the defoaming effect is better.

[0048] See also Figure 8 Combined with Fig. 9 and Fig.10The disk side wall 12 includes a disk side wall inner surface 121 , and the disk side wall inner surface 121 extends outward in an arc shape relative to the disk bottom wall 11 , and the width of the stirring chamber 13 along the horizontal direction decreases toward the disk bottom wall 11 .

[0049] As set up above, since the disk side wall 12 is arc-shaped, the arc-shaped disk side wall 12 will guide the fluid to form a more dynamic and complex flow pattern during the stirring process, generating more complex and irregular vortices, and at the same time, the vortex energy can be distributed more unevenly in the stirring area, resulting in better fluidity of the fluid (such as faster flow rate); compared with the more stable flow of a flat disk, the mixing property is better and the defoaming effect is also better.

[0050] See also Figure 8 , Fig. 9 and Fig.10 Combined with Figure 2 and Figure 4 , the heating plate assembly 10 includes a heating element 3. The structure of the heating element 3 is not limited, as long as it can achieve heating. The heating element 3 is fitted with the side wall 12 of the plate to form a contact surface 122. The blade 221 includes at least one first blade 2211 extending into the stirring chamber 13. In the vertical direction, the tip of at least one of the first blades is located between the highest point and the lowest point of the contact surface 122. In an embodiment of the present application, the contact surface 122 is a curved surface, and the curved surface in the figure is an arc surface. In other embodiments, the curved surface can also be wavy, etc. In other embodiments, the contact surface 122 can also be a plane. Of course, for the heating plate assembly 10 to realize the heating function, when only the defoaming effect is considered, the heating element can be set at any position of the heating plate assembly 10, and can also be any structure, as long as the heating plate assembly 10 has a heating function.

[0051] As described above, since the heating element 3 is arranged on the side wall 12 of the dish to form the contact surface 122, the tip of at least one first blade 2211 is located between the highest point and the lowest point of the contact surface 122. On the one hand, the food is usually located on the bottom wall 11 of the dish. After the side wall 12 of the dish is heated, the heat is transferred to the bottom wall 11 of the dish to heat the food. After the heating element 3 is arranged on the side wall 12 of the dish, it is far away from the bottom wall 11 of the dish. In this way, it is not easy to burn the bottom wall 11 of the dish. Moreover, the rotation of the first blade 2211 will also make the food in the contact surface 122 area fluid, and these foods will not stick to the side wall 12 of the dish, thereby avoiding the side wall 12 of the dish from being burned. In summary, the heating element 3 is arranged on the side wall 12 of the dish and the positional relationship between the contact surface 122 and the tip of the first blade 2211 can avoid the dish body 1 from being burned. Of course, in the case where the contact surface 122 is a curved surface, the area of ​​the curved surface is large, the heat is not concentrated, and the dish body 1 can be prevented from being burned.

[0052] See also Figure 8 , Fig. 9 and Fig.10 The height difference between the top of the blade mounting member 222 and the blade tip 2213 (in the embodiment of the present application, the blade tip 2213 is the blade tip of the second blade 2212) is d, 3mm≤d≤25mm, for example, 3mm, 5mm, 6mm, 8mm, 10mm, 12mm, 13mm, 15mm, 16mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm or 25mm.

[0053] As configured above, since 3mm≤d≤25mm, the blade mounting member 222 has a better drainage effect and enables liquid and foam to be mixed faster and better, thereby achieving a better defoaming effect.

[0054] See also Figure 8 and Fig. 9 Combined with Fig.10 The blade mounting member 222 satisfies at least one of the following characteristics:

[0055] a) In the vertical direction, the distance between the top of the blade mounting member 222 and the bottom wall 11 of the disk is H, 25mm≤H≤50mm, for example, 25mm, 26mm, 28mm, 30mm, 32mm, 33mm, 35mm, 37mm, 38mm, 40mm, 43mm, 45mm, 48mm, 49mm or 50mm.

[0056] As set above, since 25mm≤H≤50mm, the blade mounting member 222 has a better drainage effect, preventing foam from entering the stirring chamber 13, and ultimately, the heating plate assembly 10 has a better defoaming effect.

[0057] b) In the vertical direction, the distance between the top of the blade mounting member 222 and the root of the blade 221 is h, 15mm≤h≤35mm. In the embodiment of the present application, all blades 221 converge at the bottom of the blade mounting member 222. In this case, h is the distance between the top of the blade mounting member 222 and the root of any blade. In other embodiments, when the blades are distributed up and down in the axial direction of the blade mounting member 222, h is the distance between the top of the blade mounting member 222 and the root of the highest blade.

[0058] As described above, since 15 mm ≤ h ≤ 35 mm, it is not only ensured that the blade mounting member 222 has a sufficient length for better drainage, but also provides a gripping portion 2220 of sufficient length (the gripping portion 2220 is as shown in FIG. Figure 4 , Figure 7 and Figure 8 In the embodiment where the knife assembly 22 and the drive shaft 21 are detachably assembled, the knife assembly 22 can be easily disassembled and assembled by the gripping portion.

[0059] c) The blade mounting member 222 is in a columnar shape. The columnar shape may be a cylinder, or as shown in the figure, the cylinder is provided with the gripping portion 2220. The structure of the gripping portion 2220 is not limited. In the embodiment of the present application, the gripping portion 2220 is a groove that surrounds the side wall of the blade mounting member 222.

[0060] As configured above, since the blade mounting member 222 is cylindrical, the curved surface of the cylinder is more convenient for drainage, thereby achieving the defoaming effect and facilitating gripping.

[0061] See also Figure 4 and Figure 3 Combined with Figure 6 , Figure 7 and Figure 8 The drive shaft 21 is assembled to the bottom wall 11 of the disk through a bearing seat. There is no limit on how the bearing seat is assembled with the bottom wall 11 of the disk. The knife assembly 22 is assembled with the drive shaft 21 in a detachable manner. Figure 3 The diagram shows a state where the knife assembly 22 is disassembled.

[0062] As described above, since the knife assembly 22 and the drive shaft 21 are detachably assembled, the knife assembly 22 can be disassembled for cleaning, which is convenient for cleaning, and the heating element assembly 10 is clean, and the user experience is good. Because if the knife assembly 22 is not detachable, food will accumulate between the blade 221 and the bottom wall 11 of the dish, and at least one of the following three aspects (a: the obstruction of the blade 221; b) the reduction of the stirring chamber 13 toward the bottom wall 11 of the dish; c) the stickiness of the food, such as pumpkin and rice), makes this area difficult to clean and not clean.

[0063] In some embodiments, the knife assembly 22 satisfies at least one of the following conditions:

[0064] See also Figure 6 and Figure 7 The blade mounting member 222 includes an insertion hole 2221 and a mounting hole 2222 located at the bottom of the insertion hole 2221. The mounting hole 2222 is circular. Figure 4 and Figure 5 The top end of the driving shaft 21 includes a cylindrical mounting portion 211. Figure 8 The drive shaft 21 is inserted into the insertion hole 2221, and the mounting portion 211 is inserted into the mounting hole 2222. The mounting portion 211 is concentric with the mounting hole 2222.

[0065] As set up as above, because the mounting portion 211 is concentric with the mounting hole 2222, after the drive shaft 21 is inserted into the insertion hole 2221, the concentricity of the knife assembly 22 and the drive shaft 21 can be calibrated, otherwise, the center of the mounting portion and the center of the mounting hole will not coincide.

[0066] See also Figure 4 and Figure 5 , the drive shaft 21 includes an assembly section 212. The assembly section 212 includes a plurality of side edges 2123 extending in the up-down direction. The side edges 2123 are formed by the intersection of adjacent first side surfaces 2121 and second side surfaces 2122. In some embodiments, see Figure 4 , the first side surface 2121 and the second side surface 2122 can both be twisted spiral surfaces. The plurality of side edges 2123 are gradually deflected along the circumference of the assembly section 212, and the blade mounting member is provided with a driving hole matching the assembly section 212, and the driving hole includes a plurality of convex angles extending vertically in the up-down direction, and the plurality of convex angles are respectively abutted and matched with the plurality of side edges. In the above-mentioned embodiment, the blade 221 is connected to the blade mounting member 222, and the driving shaft and the blade mounting member 222 are penetrated to realize that the blade 221 is installed on the driving shaft 21 by the blade mounting member 222. In other embodiments, the blade 221 includes four blades, and the four blades converge at the connecting portion. The connecting portion is provided with a driving hole. The driving shaft 21 passes through the driving hole of the connecting portion, and the blade mounting member 222 is connected to the driving shaft 21 and abuts against the connecting portion, so that the blade 221 is installed on the driving shaft 21 by the blade mounting member 222. In yet another embodiment, the blade 221 and the blade mounting member 222 may both be provided with the driving hole, and the driving shaft passes through the driving hole.

[0067] As described above, the side edge 2123 cooperates with the convex angle to apply force to the knife assembly 22 to prevent the knife assembly 22 from being separated from the drive shaft 21. The knife assembly 22 can be disassembled and assembled by moving in different directions along the side edge, which is convenient for disassembly and assembly of the knife assembly 22.

[0068] See also Figure 1 , Figure 2 , Figure 3 , Fig. 9 and Fig.10In the second aspect, the present application discloses a food processor. The food processor includes a blending cup assembly 100 and a main unit 200. The blending cup assembly 100 includes a blending cup 20 and any one of the aforementioned heating plate assemblies 10. The heating plate assembly 10 is located at the bottom of the blending cup 20, and the plate body 1 and the blending cup 20 enclose a food cavity 101, and the food cavity 101 includes the blending cavity 13. As shown in the figure, the blending cup assembly 100 also includes a cup cover assembly 30, a handle assembly 40, a cup holder 50, a coupler 60 and a bottom cover 70. The main unit 200 includes a drive assembly, and the drive assembly drives the blade 221 to rotate in the food cavity 101. The drive assembly driving the blade 221 to rotate is not limited to being driven by a clutch as shown in the figure, and the working stages of the blade 221 include a high speed stage and a low speed stage, and the high speed stage precedes the low speed stage.

[0069] As configured above, the stirring cup assembly at least has the beneficial effects of the heating plate assembly, which will not be described in detail.

[0070] In some embodiments, the speed in the low speed stage is V, 500RPM≤V≤3000RPM. For example, when the food processor is used to make soybean milk, the knife assembly 22 needs to rotate at a high speed first and then at a low speed.

[0071] As described above, the food processor has at least the beneficial effects of the heating plate assembly, which will not be described in detail. In addition, since 500RPM≤V≤3000RPM, the knife assembly 22 is ensured to rotate at a low speed, and it is not easy to generate foam, the drainage effect of the blade mounting member 222, etc., thereby ensuring a good defoaming effect.

[0072] In some embodiments, see Fig. 9 In the vertical direction, the height of the vortex formed by the blade 221 stirring the liquid in the blending cup 20 relative to the bottom wall 11 of the plate is Q, and the height between the top of the blade mounting member 222 and the bottom wall 11 of the plate is H, 1 / 5≤H / Q≤1 / 2, for example, 25mm≤H≤50mm, 90mm≤Q≤135mm.

[0073] As described above, since 1 / 5≤H / Q≤1 / 2, once Q is determined, it can ensure that the foam moves toward the center of the vortex (and the larger the Q, the greater the rotation speed, see Fig.10 In that case, the foam will move to the side of the mixing cup). In addition, H and Q being in the above ratio range correspondingly limit the low-speed rotation of the knife assembly 22, and low-speed rotation is not easy to generate foam. Therefore, based on the above-mentioned proportional relationship and the distance relationship between the blade mounting member 222 and the blade tip, the drainage effect of the blade mounting member and the mixing of the liquid and the foam in the vortex center can be ensured, thereby ensuring that the defoaming effect of the heating plate assembly 10 is good.

[0074] The above description is only a preferred implementation mode of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
