Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processing machine. Background Technology

[0002] A food processor with a detachable and washable blade assembly that achieves non-contact transmission via magnetic drive is currently available. The transmission disk needs to rotate synchronously with the main unit's drive disk to drive the mixing blades to cut the food. The transmission disk is installed inside the blade holder of the blade assembly, and a clearance needs to be maintained between the transmission disk and the blade holder to ensure that they do not rub against each other during high-speed rotation. However, if the clearance between the transmission disk and the drive disk is too large, it will greatly reduce the transmitted torque and affect the pulverization. Therefore, precise control of the transmission clearance between the transmission disk and the drive disk is required.

[0003] The mixing cup of a food processor typically consists of an open-bottomed cup body, an open-bottomed heating plate, and a cup base. In existing assembly technology, the cup body serves as the mounting reference. The heating plate first overlaps with the stepped part of the cup base via its own flange. Then, the cup base is threaded onto the cup body. Once the cup base and cup body are securely fitted in place, the heating plate is pressed against the bottom of the cup body by the cup base. Therefore, after assembly, the heating plate is suspended relative to the bottom wall of the cup base, creating an assembly gap. This gap is uncontrollable due to the precision of the fit between the cup base and the cup body. When the mixing cup is installed in the main unit, the assembly dimension chain between the transmission disk and the drive disk includes the assembly gaps between the transmission disk and the bottom wall of the blade holder, the bottom wall of the blade holder and the heating plate, the electromagnetic drive device and the heating plate, as well as the uncontrollable gap between the heating plate and the bottom wall of the cup holder. Therefore, the assembly dimension chain between the transmission disk and the drive disk is too long and cannot be precisely controlled, resulting in excessive fluctuations in the transmission magnetic attraction force between the drive disk and the transmission disk of the food processor, reduced transmission torque, and decreased crushing efficiency. This affects the product stability of the food processor and makes it impossible to commercialize the magnetic transmission technology solution used in the food processor. Utility Model Content

[0004] This invention provides a food processing machine that solves the problem in magnetically driven food processing machines where the large size chain generated by the assembly of the stirring cup causes uncontrollable transmission distance between the drive disk and the transmission disk, resulting in large fluctuations in the transmission magnetic attraction force.

[0005] The technical solution adopted in this utility model is as follows:

[0006] This utility model provides a food processing machine, including a main unit, a mixing cup mounted on the main unit, and a blade assembly detachably mounted inside the mixing cup. The mixing cup includes a cup body, a cup base fixed to the bottom of the cup body, and a heating plate located inside the cup base and encapsulated in the bottom of the cup body. The blade assembly includes a blade holder supported on the heating plate, a transmission disk mounted inside the blade holder, a mixing blade located above the blade holder, and a transmission shaft connecting the transmission disk and the mixing blade. The main unit is equipped with an electromagnetic drive device. A clearance hole and a support ring rib extending towards the heating plate are provided on the bottom wall of the cup base. The heating plate axially abuts against the support ring rib to axially limit its position in the cup base. The heating plate has an exposed portion exposed through the clearance hole. The bottom wall of the cup base is provided with a first support portion that supports and cooperates with the top wall of the main unit. The electromagnetic drive device protrudes from the top wall of the main unit and passes through the clearance hole to approach the exposed portion. The transmission disk is located above the exposed portion and is driven remotely by the electromagnetic drive device.

[0007] This utility model provides a food processing machine. By providing clearance holes and supporting ring ribs extending towards the heating plate from the bottom wall of the cup holder, the heating plate is axially abutted against the supporting ring ribs and axially limited within the cup holder. Therefore, the heating plate uses the cup holder as the installation reference, and the cup body is also installed based on the cup holder, making the assembly reference of the mixing cup unified as the cup holder. This avoids the influence of assembly tolerances of the cup body, heating plate, and cup holder on the axial clearance between the heating plate and the cup holder. Since the heating plate is supported by the supporting ring ribs on the bottom wall of the cup holder, the two directly abut against each other, achieving precise control of the axial clearance between the bottom wall of the cup holder and the heating plate. Furthermore, the bottom wall of the cup holder is provided with a first support part that cooperates with the top wall of the main unit, thereby precisely controlling the assembly tolerance between the cup holder and the main unit. In short, this reduces the assembly dimension chain between the mixing cup and the main unit, thereby improving the more precise control of the transmission distance between the drive disk and the transmission disk, and avoiding large fluctuations in the transmission magnetic attraction force.

[0008] Based on this, by setting a clearance hole, the obstruction of the bottom wall of the cup holder is eliminated; by having the electromagnetic drive device protrude from the top wall of the main unit and pass through the clearance hole to approach the exposed part, the obstruction of the top wall of the main unit is also eliminated, thereby allowing the transmission disk to be positioned above the exposed part and driven remotely by the electromagnetic drive device. Therefore, the transmission disk and the drive disk are not obstructed by the bottom wall of the cup holder and the top wall of the main unit, further reducing the transmission distance between the transmission disk and the drive disk. In summary, this application achieves more precise control of the transmission distance between the transmission disk and the drive disk while reducing the transmission distance between them, improving the effectiveness and reliability of the transmission.

[0009] In a preferred embodiment, the heating plate includes a bottom wall that abuts against the supporting ring rib and a recessed groove from the center of the bottom wall, the groove opening facing the electromagnetic drive device to form the exposed portion, and the electromagnetic drive device extending into the groove.

[0010] By setting a sink in the heating plate, the bottom wall strength of the heating plate can be strengthened by the bending shape, preventing the heating plate from deforming. On the other hand, with the sink opening facing the electromagnetic drive device, the electromagnetic drive device extends into the sink, so that after the stirring cup is installed in place, the sink plays a certain role in limiting the radial swing of the electromagnetic drive device.

[0011] In a preferred embodiment, the bottom wall of the cup holder is further provided with a limiting ring rib surrounding the outer periphery of the supporting ring rib, the bottom wall of the heating plate abuts against the supporting ring rib, and the limiting ring rib extends to the outer periphery of the side wall of the heating plate.

[0012] By setting a support ring rib, the axial positioning of the heating plate and the cup holder is achieved. By using a limiting ring rib that surrounds the outer periphery of the support ring rib and extends to the outer periphery of the side wall of the heating plate, the radial positioning of the heating plate and the cup holder is achieved, so that the heating plate is stably installed in the cup holder.

[0013] In a preferred embodiment, the heating plate includes a bottom wall that abuts against the supporting ring rib and a side wall connected to the edge of the bottom wall. The top of the side wall is provided with an outwardly folded flange. The side wall of the cup holder is provided with a mounting boss that axially supports the flange. The flange is pressed against the bottom end of the cup body by the mounting boss. The flange is fitted with a buffer.

[0014] Because the heating plate is rigidly axially limited by the supporting ring rib of the cup holder, if there are machining errors between the cup holder and the cup body, the heating plate may not be able to fit tightly and seal with the cup body during assembly. Therefore, by setting a flange on the heating plate and using the flange to fit a buffer, when the flange is pressed by the mounting boss, the buffer is flexibly placed between the cup body and the cup holder. This absorbs the fit tolerance between the cup holder and the cup body while ensuring reliable contact between the heating plate and the supporting ring rib, so that the cup holder and the cup body are tightly connected. At the same time, the flange fitted with the buffer seals the fit seam between the cup body, the heating plate and the cup holder.

[0015] More preferably, the sidewall includes a limiting wall surrounding the knife holder and a heating wall connected to the top of the limiting wall, the flange being located at the top of the heating wall, the heating wall extending outward at an angle from bottom to top, and a heating tube being fixed to the outer side of the heating wall.

[0016] By setting a limiting wall and a heating wall, the limiting wall limits the tool holder, and the heating wall is equipped with a heating tube, so that the heating tube can be located above the tool holder. This achieves a height misalignment between the heating tube and the tool holder, allowing the heat from the heating tube to be fully transferred to the slurry above the tool holder, avoiding heat loss caused by the tool holder absorbing the heat from the heating tube, and improving heating efficiency.

[0017] In a preferred embodiment, the top wall edge of the host is provided with an annular rib surrounding the electromagnetic drive device, the annular rib and the top wall of the host form a mounting groove, and the cup seat is radially limited in the mounting groove.

[0018] The ring-shaped ribs enclose the mixing cup with the top wall of the main unit to form a mounting groove. This allows the cup holder to be axially supported by the first support part while the mounting groove provides radial restraint, ensuring stable installation of the mixing cup and the main unit and improving operational stability. Simultaneously, the mounting groove guides the mixing cup during installation, ensuring accurate positioning and proper alignment of the transmission and drive disks for reliable transmission.

[0019] In a preferred embodiment, the stirring cup is detachably mounted on the main unit, and the bottom wall of the cup holder is provided with a second support portion surrounding the outer periphery of the first support portion. The second support portion protrudes relative to the first support portion to support and cooperate with the workbench surface, and the top wall of the main unit is provided with a groove that avoids the second support portion.

[0020] By setting a second support on the bottom wall of the cup holder, the mixing cup is supported by the first support and the main unit, and supported by the second support and the worktable. This avoids wear on the first support when the mixing cup is placed on the worktable, which would otherwise lead to increased assembly tolerance between the mixing cup and the main unit and uncontrollable transmission distance. This improves the assembly accuracy between the mixing cup and the main unit during operation, and makes the transmission distance between the transmission disk and the drive disk more controllable.

[0021] In a preferred embodiment, the first support portion is a support surface that fits against the top wall of the host unit.

[0022] The first support part is a support surface that fits against the top wall of the main unit, forming a large contact area with the main unit, which improves the support strength and stability during operation.

[0023] In a preferred embodiment, the second support portion is a plurality of legs spaced apart at the edge of the first support portion.

[0024] The second support is a leg, which has a simple structure. When placed on the workbench, the leg raises the bottom wall of the cup holder, separating the bottom wall of the cup holder from the workbench. This prevents water from entering the cup holder through the clearance hole if there is water accumulation on the workbench, thus providing a waterproof effect.

[0025] In a preferred embodiment, the food processing machine further includes a housing, the cup body includes a main body segment and a constricted segment connected below the main body segment, the cup holder is sleeved and fixed to the constricted segment, the housing is fitted over the cup holder and extends to the outer periphery of the main body segment, and a sealing ring is provided between the top of the housing and the main body segment.

[0026] By designing an outer shell that integrates the cup body and the base together, the cup body is prevented from getting too hot to handle. At the same time, the outer shell protects both the cup body and the base, enclosing the mating area and improving the sealing and waterproofing effect, resulting in a consistent appearance for the blending cup.

[0041] like Figure 1-6As shown, in one embodiment, this utility model provides a food processing machine, including a main unit 10, a mixing cup 20 mounted on the main unit 10, and a blade assembly 30 detachably mounted inside the mixing cup 20. The mixing cup 20 includes a cup body 21, a cup base 23 fixed to the bottom of the cup body 21, and a heating plate 22 located inside the cup base 23 and encapsulated in the bottom of the cup body 21. The blade assembly 30 includes a blade holder 31 supported on the heating plate 22, a transmission disk 32 mounted inside the blade holder 31, a mixing blade 33 located above the blade holder 31, and a transmission shaft 34 connecting the transmission disk 32 and the mixing blade 33. The main unit 10 is equipped with an electromagnetic drive device 11, such as... Figure 2 As shown, a clearance hole 231 and a support ring rib 232 extending around the clearance hole 231 and toward the heating plate 22 are provided on the bottom wall of the cup holder 23. The heating plate 22 and the support ring rib 232 are axially abutted to limit the heating plate 22 in the cup holder 23. The heating plate 22 has an exposed part that is exposed through the clearance hole 231. The bottom wall of the cup holder 23 is provided with a first support part 233 that cooperates with the top wall of the host 10. The electromagnetic drive device 11 protrudes from the top wall of the host 10 and passes through the clearance hole 231 to approach the exposed part. The transmission disk 32 is located above the exposed part and is driven by the electromagnetic drive device 11 in the air.

[0042] In this embodiment, such as Figure 1 , 2 As shown in Figure 3, the electromagnetic drive device 11 includes a motor 12 and a drive disk 13 driven by the motor 12. The drive disk 13 is located below the transmission disk 32 and drives the transmission disk 32 to rotate. The drive disk 13 protrudes from the top wall of the host 10 and passes through the clearance hole 231 to approach the exposed part.

[0043] The food processing machine provided by this utility model has a clearance hole 231 and a supporting ring rib 232 extending around the clearance hole 231 and toward the heating plate 22 on the bottom wall of the cup holder 23. The heating plate 22 is axially abutted against the supporting ring rib 232 and axially limited in the cup holder 23. Therefore, the heating plate 22 is installed with the cup holder 23 as the mounting reference, and the cup body 21 is also installed based on the cup holder 23. This makes the assembly reference of the mixing cup 20 uniformly the cup holder 23, avoiding the assembly tolerance of the cup body 21, heating plate 22 and cup holder 23 affecting the axial direction between the heating plate 22 and the cup holder 23. The impact of the gap is mitigated because the heating plate 22 is supported by the supporting ring rib 232 on the bottom wall of the cup holder 23, and the two directly abut against each other, achieving precise control of the axial gap between the bottom wall of the cup holder 23 and the heating plate 22. Furthermore, the bottom wall of the cup holder 23 is provided with a first support part 233 that cooperates with the top wall of the main unit 10, thereby precisely controlling the assembly tolerance between the cup holder 23 and the main unit 10. In short, the assembly dimension chain between the stirring cup 20 and the main unit 10 is reduced, thereby improving the more precise control of the transmission distance between the drive disk 13 and the transmission disk 32.

[0044] Based on this, by providing the clearance hole 231, the obstruction of the bottom wall of the cup holder 23 is eliminated; by having the electromagnetic drive device 11 protrude from the top wall of the main unit 10 and pass through the clearance hole 231 to be close to the exposed part, the obstruction of the top wall of the main unit 10 is also eliminated, thereby allowing the transmission disk 32 to be positioned above the exposed part and driven remotely by the electromagnetic drive device 11. Therefore, the transmission disk 32 and the drive disk 13 are not obstructed by the bottom wall of the cup holder 23 and the top wall of the main unit 10, further reducing the transmission distance between the transmission disk 32 and the drive disk 13. In summary, this application achieves more precise control of the transmission distance between the transmission disk 32 and the drive disk 13 while reducing the transmission distance between them, thus improving the effectiveness and reliability of the transmission.

[0045] Of course, it should be noted that the structure of the electromagnetic drive device 11 is not limited to the one described above. In other embodiments, the electromagnetic drive device 11 includes a stator and a coil winding wound around the stator. The coil winding is energized to generate a magnetic field to drive the transmission disk 32 to rotate. The top of the stator protrudes from the top wall of the host 10 and passes through the clearance hole 231 to approach the exposed part.

[0046] like Figure 2 As shown, in a preferred embodiment, the bottom wall of the cup holder 23 is further provided with a limiting ring rib 235 surrounding the outer periphery of the supporting ring rib 232, the bottom wall of the heating plate 22 abuts against the supporting ring rib 232, and the limiting ring rib 235 extends to the outer periphery of the side wall of the heating plate 22.

[0047] By setting the support ring 232, the axial positioning of the heating plate 22 and the cup holder 23 is achieved. The limiting ring 232 is used to surround the outer periphery of the support ring 232 and extends to the outer periphery of the side wall of the heating plate 22, thereby achieving the radial positioning of the heating plate 22 and the cup holder 23, so that the heating plate 22 is stably installed in the cup holder 23.

[0048] like Figure 3 As shown, in a preferred embodiment, the top wall edge of the host 10 is provided with an annular rib 101 surrounding the electromagnetic drive device 11. The annular rib 101 and the top wall of the host 10 enclose a mounting groove, and the cup seat 23 is radially limited in the mounting groove.

[0049] The annular rib 101 forms an installation groove with the top wall of the main unit 10, allowing the cup holder 23 to be axially supported by the first support part 233 on the main unit 10, while the installation groove provides radial restraint, thus achieving stable installation of the mixing cup 20 and the main unit 10 and improving operational stability. Simultaneously, the installation groove guides the installation of the mixing cup 20, ensuring accurate positioning and proper alignment of the transmission disk 32 and the drive disk 13, achieving reliable transmission.

[0050] like Figure 3 ,4 As shown in Figure 5, in a preferred embodiment, the stirring cup 20 is detachably installed on the main unit 10, and the bottom wall of the cup holder 23 is provided with a second support 234 surrounding the outer periphery of the first support 233. The second support 234 protrudes relative to the first support 233 to support and cooperate with the workbench surface. The top wall of the main unit 10 is provided with a groove that avoids the second support 234.

[0051] By providing a second support 234 on the bottom wall of the cup holder 23, the stirring cup 20 is supported and cooperated with the main unit 10 by the first support 233 and with the worktable by the second support 234. This avoids wear on the first support 233 when the stirring cup 20 is placed on the worktable, which would lead to increased assembly tolerance between the stirring cup 20 and the main unit 10 and uncontrollable transmission distance. This improves the assembly accuracy between the stirring cup 20 and the main unit 10 during operation, so as to make the transmission distance between the transmission disk 32 and the drive disk 13 more controllable.

[0052] It should be noted that the present invention does not limit the specific structure of the first support part 233 and the second support part 234. For example, the first support part 233 may be a support surface that fits against the top wall of the main unit 10 or the first support part 233 may be a support rib. The second support part 234 may be a plurality of legs spaced apart on the edge of the first support part 233 or the second support part 234 may be a ring rib.

[0053] The first support part 233 is a support surface that fits against the top wall of the main unit 10, forming a large contact area with the main unit 10, thereby improving support strength and stability during operation. The second support part 234 is a support leg with a simple structure. When placed on a workbench, the support leg raises the bottom wall of the cup holder 23, separating the bottom wall of the cup holder 23 from the workbench. This prevents water from entering the cup holder 23 through the clearance hole 231 in case of water accumulation on the workbench, thus providing a waterproof effect.

[0054] like Figure 2 , 4 As shown, in a preferred embodiment, the heating plate 22 includes a bottom wall that abuts against the supporting ring rib 232 and a recessed groove 220 from the center of the bottom wall. The groove opening of the groove 220 faces the electromagnetic drive device 11 to form an exposed portion, and the electromagnetic drive device 11 extends into the groove 220.

[0055] By setting a sink in the heating plate 22, on the one hand, the bottom wall strength of the heating plate 22 can be strengthened by the bending shape to prevent the heating plate 22 from deforming. On the other hand, with the sink opening facing the electromagnetic drive device 11, the electromagnetic drive device 11 extends into the sink, so that after the stirring cup 20 is installed in place, the sink plays a certain role in limiting the radial swing of the electromagnetic drive device 11.

[0056] like Figure 6 As shown, in a preferred embodiment, the heating plate 22 includes a bottom wall that abuts against the supporting ring rib 232 and a side wall connected to the edge of the bottom wall. The top of the side wall is provided with an outwardly folded flange 221. The side wall of the cup seat 23 is provided with a mounting boss that axially supports the flange 221. The flange 221 is pressed against the bottom end of the cup body 21 by the mounting boss. The flange 221 is sleeved with a buffer member 222.

[0057] In this embodiment, a mounting bracket is fixed to the side wall of the cup holder 23, and a mounting boss is provided on the flange 221 of the heating plate 22 supported by the mounting bracket. In fact, the cup holder 23 can be directly provided with a mounting boss supporting the flange 221 of the heating plate 22.

[0058] Since the heating plate 22 is rigidly axially limited by the support ring 232 of the cup seat 23, if there is a machining error between the cup seat 23 and the cup body 21, the heating plate 22 may not be able to fit tightly and seal with the cup body 21 during assembly. Therefore, by setting a flange 221 on the heating plate 22 and using the flange 221 to fit the buffer 222, when the flange 221 is pressed by the mounting boss, the buffer 222 is flexibly set between the cup body 21 and the cup seat 23. This absorbs the fit tolerance between the cup seat 23 and the cup body 21 while ensuring that the heating plate 22 and the support ring 232 reliably abut against each other, so that the cup seat 23 and the cup body 21 are tightly connected. At the same time, the flange 221 fits the buffer 222, so that the buffer 222 seals the fit seam between the cup body 21, the heating plate 22 and the cup seat 23.

[0059] like Figure 5 As shown, more preferably, the sidewall includes a limiting wall 201 surrounding the knife holder 31 and a heating wall 202 connected to the top of the limiting wall 201. The flange 221 is located at the top of the heating wall 202. The heating wall 202 extends outward from bottom to top at an angle. A heating tube 40 is fixed to the outer side of the heating wall 202.

[0060] By setting a limiting wall 201 and a heating wall 202, the limiting wall 201 limits the tool holder 31, and the heating wall 202 is used to install the heating tube 40, so that the heating tube 40 can be located above the tool holder 31. This achieves a height misalignment between the heating tube 40 and the tool holder 31, allowing the heat from the heating tube 40 to be fully transferred to the slurry above the tool holder 31, avoiding heat loss caused by the tool holder 31 absorbing the heat from the heating tube 40, and improving heating efficiency.

[0061] This invention does not limit the specific structure of the stirring cup, for example, as... Figure 6As shown, in a preferred embodiment, the food processing machine further includes a housing 24, a cup body 21 including a main body section and a constricted section connected below the main body section, a cup holder 23 sleeved and fixed to the constricted section, a housing 24 sleeved outside the cup holder 23 and extending to the outer periphery of the main body section, and a sealing ring 25 is provided between the top of the housing 24 and the main body section.

[0062] By setting the outer shell 24 to fit the cup body 21 and the cup base 23 together, the cup body 21 is prevented from getting hot to the touch. At the same time, the cup body 21 and the cup base 23 are protected together, and the mating parts of the cup body 21 and the cup base 23 are wrapped to improve the sealing and waterproof effect of the mating parts, so that the appearance of the mixing cup 20 is consistent.

[0063] In other implementation examples, the outer shell is omitted, and the cup holder is directly and sealed onto the outside of the contraction section of the cup body, which is a glass cup body, thus enabling visualization of the processing.

[0064] Alternatively, in other implementation examples, the cup holder extends from the bottom of the cup body to the rim of the cup body and seals with the top of the cup body to enclose the cup body. This eliminates the need for an additional outer shell, simplifies the structure of the mixing cup, and also provides a scalding protection effect.
