Abstract

The utility model discloses a food processor. The food processor comprises a stirring cup, a stirring knife assembly and a motor. The stirring cutter assembly comprises a cutter shaft and a blade assembled on the cutter shaft. The motor comprises a stator assembly and a rotor assembly which are oppositely arranged, and the rotor assembly is assembled with the cutter shaft. The magnetic force between the stator assembly and the rotor assembly drives the rotor assembly to rotate so as to drive the blades of the stirring cutter assembly to rotate in the stirring cup.

Description

Technical Field

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

[0002] Food processors, such as the commonly used household blender, typically have a high-speed motor whose output shaft is connected to the blending blade assembly via a clutch. Conventional drive motors (series motors) require a rated blending speed exceeding 10,000 rpm to achieve sufficient and rapid blending. While series motors offer a simple structure, low cost, and high speed, their carbon brush commutation leads to a short motor lifespan, high noise levels, and a high axial mounting height, requiring significant space for the entire machine. Furthermore, the rigidly connected blade shaft and clutch still contribute to high-speed blending noise. Utility Model Content

[0003] The present application aims to disclose a food processor that operates with low noise and has a low height.

[0004] The present application discloses a food processor. The food processor includes a blending cup, a blending blade assembly, and a motor. The blending blade assembly includes a blade shaft and a blade assembled to the blade shaft. The motor includes a stator assembly and a rotor assembly disposed relative to each other, the rotor assembly being assembled to the blade shaft. The magnetic force between the stator and rotor assemblies drives the rotor assembly to rotate, thereby driving the blade of the blending blade assembly to rotate within the blending cup.

[0005] As described above, the food processor includes a motor, a rotor assembly, and a blade shaft of a mixing blade assembly, and the rotor assembly is driven by the magnetic force between the rotor assembly and the stator assembly. Consequently, the food processor lacks rigid connections such as a clutch, as is common with conventional motors. This effectively reduces overall vibration and noise caused by the motor's operation, and / or noise generated by the interaction of the upper and lower clutches, resulting in low noise during operation. Furthermore, the relative positioning of the motor's rotor assembly and stator assembly creates a planar air gap and an axial magnetic field within the air gap, effectively reducing the height of the food processor.

[0006] In some embodiments, the food processor includes a blending cup assembly and a base, the blending cup assembly is placed on the base, and the blending cup assembly includes the blending cup, the blending blade assembly, and the motor.

[0007] As configured above, since the blending cup assembly includes the motor and the blending cup assembly is placed on the base, the air gap between the rotor assembly and the stator assembly is also small, the rotor assembly can rotate more forcefully, and the food crushing effect is better; in addition, the blending cup assembly can be conveniently placed on the base or removed from the base without overcoming the magnetic force between the rotor assembly and the stator assembly.

[0008] In some embodiments, the rotor assembly and the stator assembly are both disc-shaped, and the rotor assembly and the stator assembly are parallel in the axial direction of the knife shaft to achieve the relative arrangement.

[0009] As described above, since the rotor assembly and the stator assembly are parallel in the axial direction of the blade shaft, the relative arrangement is achieved, which more effectively reduces the height of the food processor. In particular, when the rotor assembly and the stator assembly are both arranged in the blender cup assembly, the height of the food processor can be further reduced.

[0010] In some embodiments, the blending cup assembly includes a rotor holder and a cup holder; the rotor holder is assembled with the blending cup; the blade shaft is rotatably assembled with the rotor holder through a bearing; the cup holder is assembled with the rotor holder to form a receiving space; the stator assembly is assembled with the rotor holder and is located in the receiving space.

[0011] As set up above, the blending cup can be assembled with the rotor fixing frame, the blending blade assembly can be assembled with the rotor fixing frame, the rotor assembly can be assembled with the blade shaft, the stator assembly can be assembled with the rotor fixing frame, and finally, the cup holder can be assembled with the rotor fixing frame so that the stator assembly is located in the accommodating space. The blending cup assembly is simple to assemble.

[0012] In some embodiments, the food processor includes a blending cup assembly and a base, the blending cup assembly includes the blending cup, the blending blade assembly and the rotor assembly, and the base is provided with the stator assembly.

[0013] As described above, because a motor is used and the rotor assembly is connected to the blade shaft of the stirring blade assembly, even if a split design is adopted, the food processor has low noise during operation and effectively reduces the height of the food processor.

[0014] In some embodiments, the blending cup assembly includes a rotor fixing frame, and the blade shaft is rotatably assembled with the rotor fixing frame; the blending cup assembly includes a heating plate assembly, and the heating plate assembly is assembled to the rotor fixing frame, and a heat insulation device is provided between the heating plate assembly and the rotor assembly.

[0015] As described above, by providing the heating plate assembly and cooperating with the motor, the food processor can heat food (such as soy milk) while maintaining low operating noise and a low axial height, making the food processor convenient to use. Furthermore, the heat insulation device effectively isolates the magnetic material within the rotor assembly from the effects of the heating temperature, thereby preventing demagnetization.

[0016] In some embodiments, the rotor assembly and the heating plate assembly are located on both sides of the rotor fixing frame, the thermal insulation device is a thermal insulation material applied on the rotor fixing frame, or the rotor fixing frame is made of a thermal insulation material, and the thermal insulation device is the rotor fixing frame.

[0017] As set up above, the heat insulation device is the heat insulation material laid on the rotor fixing frame, or the rotor fixing frame is made of heat insulation material, and the heat insulation device is the rotor fixing frame, which will not increase the axial height of the mixing cup assembly, ensuring that the height of the food processor is low.

[0018] In some embodiments, the rotor assembly includes a rotor housing and blades, and the rotor housing and the blades are integrally formed.

[0019] As described above, since the fan blades and the rotor housing are integrally formed, they can be made by a set of molds, eliminating the step of assembling the fan blades and the rotor housing, and the structural strength is also high. For example, the structural strength will not be affected by the connection structure between the fan blades and the rotor housing.

[0020] In some embodiments, the fan blades are evenly distributed on the sidewalls of the rotor housing.

[0021] As described above, since the fan blades are evenly distributed on the side walls of the rotor housing, the fan blades rotate synchronously with the rotor housing, thereby generating wind better.

[0022] In some embodiments, the stator assembly includes a stator housing, a stator core, and a stator winding; the stator housing includes a receiving cavity for accommodating the stator core and the stator winding, and at least one of the bottom and side wall of the stator housing is provided with a heat dissipation hole connected to the receiving cavity.

[0023] As described above, by providing the heat dissipation holes, the heat dissipation of the motor can be effectively improved.

[0024] In some embodiments, the stator assembly includes a stator housing, which includes a accommodating cavity; the stator assembly includes a winding bobbin for assembling a stator core and a stator winding; the winding bobbin circumferentially includes a circle of flanges and a turnbuckle located below the flange, and the flange has spaced positioning notches; the inner wall of the accommodating cavity is provided with a positioning block and a mating buckle; the positioning block passes through the positioning notch and moves on the flange until the turnbuckle and the mating buckle are locked.

[0025] As set up above, through the cooperation of the positioning notch and the positioning block, combined with the locking of the winding frame and the stator housing by rotation, the assembly of the stator assembly is simple, and the stator winding, winding frame and stator core will not fall out of the accommodating cavity.

[0026] In some embodiments, the stator assembly includes a stator housing, a stator winding, a stator core, and a winding bobbin. The stator winding, the stator core, and the winding bobbin are all located within the stator housing. The winding bobbin includes a winding portion, the stator winding is wound around the outer wall of the winding portion in a radial plane of the stator housing, and the stator core is located within the winding portion.

[0027] In the above arrangement, the stator winding is wound around the outer wall of the winding portion in a radial plane of the stator housing. The stator core is located inside the winding portion. Thus, the planar winding of the stator winding can effectively control the axial dimension of the motor, reduce the axial installation space of the entire machine, and effectively reduce the height of the food processor.

[0042] See also Figure 2 、 Figure 3 and Figure 4 and combined Figure 1 The present application discloses a food processor. The food processor includes a blending cup 1, a blending blade assembly 2, and a motor 3. The blending blade assembly 2 includes a blade shaft 21 and a blade 22 assembled on the blade shaft 21. The motor 3 includes a rotor assembly 31 and a stator assembly 32 that are relatively arranged. There is no limit to how the rotor assembly 31 and the stator assembly 32 are relatively arranged, as long as the magnetic force between the rotor assembly 31 and the stator assembly 32 can drive the rotor assembly 31 to rotate. The rotor assembly 31 is assembled with the blade shaft 21. There is no limit to how the assembly is assembled. Figure 5 and combined Figure 3 and Figure 4The blade shaft 21 and the rotor assembly 31 are assembled together by mounting screws 211. The magnetic force between the stator assembly 32 and the rotor assembly 31 drives the rotor assembly 31 to rotate, thereby driving the blade 22 of the mixing blade assembly 2 to rotate in the mixing cup 1.

[0043] As described above, since the food processor includes a motor 3, a rotor assembly 31 of the motor 3, and a blade shaft 21 of the stirring blade assembly 2, and the rotor assembly 31 is driven by the magnetic force between the rotor assembly 31 and the stator assembly 32, the food processor does not have a hard connection such as a clutch as a traditional motor, effectively reducing the vibration and noise of the entire machine caused by the operation of the motor, and / or the noise generated by the cooperation of the upper clutch and the lower clutch, and the food processor has low noise during operation. In addition, the rotor assembly 31 and the stator assembly 32 of the motor 3 are arranged relative to each other, the air gap of the motor 3 is planar, and the air gap magnetic field is axial, which effectively reduces the height of the food processor. For example, compared with a series-excited motor method, the weight is reduced by 50%, and the axial height is reduced by 50%. Compared with a structure in which an active magnetic drive component is provided on the motor and a driven magnetic component is connected to the blade shaft, the height of the food processor can also be reduced because a motor is not provided.

[0044] See also Figure 3 and Figure 4 and combined Figure 1 and Figure 2 The food processor includes a blending cup assembly 10 and a base 20, wherein the blending cup assembly 10 is placed on the base 20. The blending cup assembly 10 includes the blending cup 1, the blending blade assembly 2, and the motor 3. The blending cup assembly 10 also includes a cup cover assembly 91 that covers the blending cup 1 and a handle assembly 92 that facilitates the handling of the blending cup assembly 10.

[0045] As configured above, since the blending cup assembly 10 includes the motor 3 and the blending cup assembly 10 is placed on the base 20, the air gap between the rotor assembly 31 and the stator assembly 32 is also small, and the rotor assembly 31 can rotate more forcefully, thereby achieving a better food crushing effect. In addition, the blending cup assembly 10 can be conveniently placed on or removed from the base 20 without overcoming the magnetic force between the rotor assembly 31 and the stator assembly 32.

[0046] In the above embodiment, the motor 3 is built into the blender cup assembly 10 (named as an integral built-in type to distinguish it from the subsequent split type). However, technicians can also understand that the rotor assembly 31 and the stator assembly 32 can be separated, and the stator assembly 32 can be set on the base 20, and the rotor assembly 31 can be set on the blender cup assembly 10 to form a split type.

[0047] As described above, because the motor 3 is used and the rotor assembly 31 is connected to the blade shaft 21 of the stirring blade assembly 2, even if a split design is adopted, the food processor has low noise during operation and effectively reduces the height of the food processor.

[0048] In the above-mentioned integral built-in embodiment, the air gap between the rotor assembly 31 and the stator assembly 32 is h, 1mm≤h≤5mm.

[0049] As set above, due to 1mm≤h≤5mm, the air gap is small, the magnetic force between the stator assembly 32 and the rotor assembly 31 is large, the blade 22 of the stirring knife assembly 2 rotates more powerfully, and the food crushing effect is better.

[0050] See also Figure 8 and combined Figure 3 and Figure 4 For the integrated built-in type, the rotor assembly 31 and the stator assembly 32 are both disc-shaped and arranged parallel to the axis of the blade shaft 21, thereby achieving the relative arrangement. In other words, the plane in which the rotor assembly 31 and the stator assembly 32 lie is perpendicular to the axis of the blade shaft 21. A motor in which both the rotor assembly 31 and the stator assembly 32 are disc-shaped is, for example, an axial flux motor.

[0051] For the split type, the arrangement between the rotor assembly 31 and the stator assembly 32 is the same as that of the integral built-in type, except that the axial spacing between the rotor assembly 31 and the stator assembly 32 on the blade shaft 21 is larger than that of the integral built-in type.

[0052] As described above, since the rotor assembly 31 and the stator assembly 32 are parallel in the axial direction of the blade shaft 21, the relative arrangement is achieved, which more effectively reduces the height of the food processor, especially when the rotor assembly 31 and the stator assembly 32 are both arranged in the blender cup assembly 10, the height of the food processor can be further reduced.

[0053] See also Figure 5 、 Figure 4 and Figure 3 The blending cup assembly 10 includes a rotor fixing frame 4 and a cup holder 5. The rotor fixing frame 4 is assembled with the blending cup 1. The blade shaft 21 is assembled with the rotor fixing frame 4 through the bearing 23. There is no limit to the assembly method. Figure 5 and Figure 4 The mixing cup assembly 10 includes a bearing fixing frame 24, and the bearing fixing frame 24 and the rotor fixing frame 4 respectively include mounting holes 48 (only in Figure 7The mounting holes 48 on the rotor mount 4 are shown in the figure. Bolts pass through the mounting holes 48 of the bearing mount 24 and the rotor mount 4 and are fixed with nuts. Thus, the blade shaft 21 is rotatably connected to the rotor mount 4. The cup holder 5 is assembled with the rotor mount 4 to form a receiving space 51. The stator assembly 32 is assembled with the rotor mount 4 and is located in the receiving space 51. Figure 6 and combined Figure 4 、 Figure 7 The rotor mounting frame 4 includes a mounting portion 49 and a stator housing 321 of the stator assembly 32. The stator housing 321 is provided with a screw hole 3219. A fixing screw 3218 passes through the screw hole 3219 and is locked with the mounting portion 49, thereby assembling the stator assembly 32 to the rotor mounting frame 4.

[0054] As described above, the blending cup 1 can be assembled with the rotor fixing frame 4, the blending blade assembly 2 can be assembled with the rotor fixing frame 4, the rotor assembly 31 can be assembled with the blade shaft 21, and the stator assembly 32 can be assembled with the rotor fixing frame 4. Finally, the cup holder 5 can be assembled with the rotor fixing frame 4 so that the stator assembly 32 is located in the accommodating space 51. The blending cup assembly 10 is simple to assemble.

[0055] The above describes the assembly of the rotor fixing frame 4 and the rotor assembly 31 . Those skilled in the art will appreciate that, for the above-mentioned split type, the assembly of the rotor assembly 31 and the rotor fixing frame 4 may also be performed in the above-mentioned manner.

[0056] See also Figure 4 and combined Figure 3 The blending cup assembly 10 includes a rotor fixing frame 4, and the blade shaft 21 is rotatably assembled with the rotor fixing frame 4. For how to rotatably connect, please refer to the above. The blending cup assembly 10 includes a heating disk assembly 6. The heating disk assembly 6 is assembled on the rotor fixing frame 4, and a heat insulation device is provided between the heating disk assembly 6 and the rotor assembly 31. The structure of the heat insulation device is not limited, as long as the heat generated by the heating disk assembly 6 does not affect the performance of the motor 3, for example, it does not cause the motor 3 to be demagnetized.

[0057] As described above, by providing the heating plate assembly 6 and cooperating with the motor 3, the food processor can heat food (such as soy milk) while maintaining low operating noise and a low axial height, making the food processor convenient to use. In addition, the heat insulation device effectively isolates the magnetic material in the rotor assembly from the effects of the heating temperature, thereby preventing demagnetization.

[0058] See also Figure 4 、 Figure 5 and Figure 2 and combined Figure 7The rotor assembly 31 and the heating plate assembly 6 are located on both sides of the rotor fixing frame 4. Figure 4 As a reference, the heating plate assembly 6 is located on the upper side of the rotor fixing frame 4, and the rotor assembly 31 is located on the lower side of the rotor fixing frame 4. Figure 7 , the heat insulation device is the heat insulation material 41 laid on the rotor fixing frame 4. The heat insulation material 41 is not limited, for example, it is a heat insulation sheet or heat insulation film laid on the upper surface of the rotor fixing frame 4 facing the heating disk assembly 6. In some embodiments, the rotor fixing frame 4 is made of heat insulation material. The heat insulation device is the rotor fixing frame

[0059] As set up above, the heat insulation device is the heat insulation material 41 laid on the rotor fixing frame 4, or the rotor fixing frame 4 is made of heat insulation material, and the heat insulation device is the rotor fixing frame, which will not increase the axial height of the mixing cup assembly 10, ensuring that the height of the food processor is low.

[0060] In this embodiment, the rotor fixing frame 4 includes a fixing frame bottom wall 42 and a fixing frame side wall 43. The fixing frame bottom wall 42 is arched and has an installation space 421. The blade shaft 21 passes through the top of the fixing frame bottom wall 42 and is rotatably connected to the top of the fixing frame bottom wall 42. The rotor assembly 31 is located in the installation space 421. In the embodiment of the present application, the bearing 23 and the bearing fixing frame 24 are also located in the installation space 421. The heat insulation material 41 is applied to the fixing frame bottom wall 42, for example, the surface of the arch. The fixing frame bottom wall 42, the fixing frame side wall 43 and the heating disk assembly 6 form a closed cavity 60, and the components of the heating disk assembly 6 (such as the heating tube 61, the thermostat, etc.) are located in the closed cavity 60.

[0061] As described above, since the rotor fixing frame 4 is arched and has the installation space 421 and forms a closed cavity 60 with the heating plate assembly 6, the rotor assembly 31 is located in the installation space 421, the heat insulation material 41 is applied to the bottom wall 42 of the mounting frame, and the components of the heating plate assembly 6 are located in the closed cavity 60. In this way, the food processor has a compact structure and a small size.

[0062] See also Figure 8 and Figure 9 and combined Figure 5, the rotor assembly 31 includes a rotor housing 311 and a fan blade 312. The rotor housing 311 and the fan blade 312 are integrally formed. In an embodiment of the present application, the rotor assembly 31 includes a magnetic sheet 313 (such as an aluminum iron boron magnetic sheet) and a magnetic conductive sheet 314. The rotor housing 311 includes a magnetic sheet mounting slot 3111. The magnetic sheet 313 is pressed against the magnetic sheet mounting slot 3111 and bonded to the magnetic sheet mounting slot 3111. The magnetic conductive sheet 314 and the rotor housing 311 can be assembled in any structure. With such a configuration, the assembly steps can be reduced, and the assembly between the components of the rotor assembly 31 is simple. The number of magnetic sheets 313 is not limited. For example, the number of magnetic sheets 313 enables the rotor assembly 31 to include even-pole magnetic poles such as a 4-pole rotor, a 6-pole rotor, and an 8-pole rotor.

[0063] As described above, since the fan blades 312 and the rotor housing 311 are integrally formed, they can be made by a set of molds, thereby eliminating the step of assembling the fan blades 312 and the rotor housing 311, and the structural strength is also high. For example, the structural strength will not be affected by the connection structure between the fan blades 312 and the rotor housing 311.

[0064] In some embodiments, the fan blades 312 are evenly distributed on the sidewall of the rotor housing 311 .

[0065] As described above, since the fan blades 312 are evenly distributed on the side walls of the rotor housing 311, the fan blades 312 rotate synchronously with the rotor housing 311, thereby generating wind better.

[0066] See also Figure 10 and Figure 8 and combined Figure 4 The stator assembly 32 includes a stator housing 321, a stator core 322, and a stator winding 323. The stator housing 321 includes a housing cavity 3211 for accommodating the stator core 322 and the stator winding 323. In the integral built-in type, the stator housing 321 is assembled with the rotor mounting frame 4. In the split type, the stator housing 321 is assembled with the corresponding portion of the base 20. Figure 4 Schematically, the bottom of the stator housing 321 is provided with a heat dissipation hole 3222 that communicates with the accommodating cavity 3211. In some embodiments, the heat dissipation hole 3222 may also be provided on the side wall of the stator housing 321. In short, the heat dissipation hole 3222 may be provided on at least one of the bottom or side wall of the stator housing 321.

[0067] As described above, by providing the heat dissipation holes 3222 , the heat dissipation of the motor 3 can be effectively improved.

[0068] See also Figure 11 and Figure 12 and combined Figure 10The stator assembly includes a stator housing 321, and the stator housing 321 includes a receiving cavity 3211. The stator assembly 32 includes a winding bobbin 324 for assembling a stator core 322 and a stator winding 323. The winding bobbin 324 includes a circle of flanges 3243 and a turn button 3244 located below the flange 3243 in the circumference. The structure of the turn button 3244 is not limited, for example, it is a card slot. The flange 3243 has spaced positioning notches 3245. The structure of the positioning notches 3245 is not limited. In this embodiment, the positioning notches 3245 divide the flange 3243 into multiple sections. The inner wall of the receiving cavity 3211 is provided with a positioning block 3212 and a mating buckle 3213. The positioning block 3212 passes through the positioning notch 3245 and moves on the flange 3243 until the turn button 3242 and the mating buckle 3213 are locked.

[0069] As described above, the stator winding 323 and the stator core 322 are assembled on the winding frame 324, and then the positioning notch 3245 and the positioning block 3212 are matched, and the winding frame 324 is locked with the stator housing 321 by rotation. The assembly of the stator assembly 32 is simple, and the stator winding, winding frame and stator core will not fall out of the accommodating cavity.

[0070] See also Figure 11 、 Figure 12 、 Figure 10 and Figure 8 and combined Figure 4 The stator assembly 32 includes a stator housing 321, a stator winding 323, a stator core 322, and a winding bobbin 324. The stator winding 323, the stator core 322, and the winding bobbin 324 are all located within the stator housing 321. The winding bobbin 324 includes a winding portion 3241. The stator winding 323 is wound around the outer wall of the winding portion 3241 in a radial plane of the stator housing 321. The stator core 322 is located inside the winding portion 3241 (for example, within the hole 3242 of the winding portion 3241).

[0071] As described above, since the stator winding 323 is wound around the outer wall of the winding portion 3241 in the radial plane of the stator housing 321, the stator core 322 is located inside the winding portion 3241. Thus, the stator winding 323 is wound in a plane (which can be understood as winding on a horizontal plane), which can effectively control the axial dimension of the motor 3, reduce the axial installation space of the entire machine, and effectively reduce the height of the food processor.

[0072] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
