Outer rotor motor and food processor

By incorporating a baffle in the external rotor motor, the rotation direction is altered by the impact of the baffle claws with the food, enabling multiple cycles of pulverization. This solves the problem of poor pulverization performance in existing food processors and improves the pulverization effect.

[0021] The outer rotor motor 100 can be used in a food processor, a soybean milk machine, or the like as a driving mechanism. In one embodiment, the food processor includes a cup body and a head. A head cover is arranged on the cup body, and the head includes a cup cover and an outer rotor motor.

[0022] Referring to Figures 1 to 6 The outer rotor motor 100 includes a main shaft 10, a motor stator 20, a motor rotor 30, and a housing 40. The motor stator 20 is sleeved on the main shaft 10, the motor rotor 30 is sleeved on the motor stator 20, and the housing 40 is sleeved on the motor rotor 30. A crushing assembly 50 is arranged at the bottom end of the motor rotor 30, and a turbulence member 45 is arranged at the bottom end of the housing 40. The turbulence member 45 includes a turbulence claw 451 arranged outside the crushing assembly 50. The crushing assembly 50 and the turbulence member 45 extend into the cup body, respectively.

[0023] The main shaft 10 is fixed with a support 11 at the top end, and is provided with bearings 15 at the upper and lower ends. The motor stator 20 includes a core 21, end frames 22 arranged at both ends of the core 21, a PCB wire frame 23 arranged above the end frames 22, and a coil winding (not shown) arranged around the core 21 and the end frames 22. The motor rotor 30 includes a rotor shell 31, magnets 32, and magnet frames 33 at both ends of the magnets 32, which function to position the magnets 32. The rotor shell 31 is matched with the bearings 15 at the upper and lower ends. The outer shell 40 is arranged outside the rotor shell 31, and the top end of the outer shell 40 is fixed with the support 11.

[0024] Since the spoiler 45 is arranged at the bottom end of the outer shell 40, and the spoiler 45 includes spoiler claws 451 outside the crushing assembly 50, the food materials are stirred during the rotation of the crushing assembly 50, and the food materials change the rotation direction when colliding with the spoiler 45, thereby having the effect of turbulence. Part of the food materials move towards the crushing assembly 50 after colliding with the spoiler 45, and are stirred and cut again by the crushing assembly 50, so as to be repeatedly circulated, so that the crushing of the food materials is more delicate, and the crushing effect is better.

[0025] The spoiler claws 451 have spoiler surfaces 452 at the ends, and the included angle R between the spoiler surfaces 452 and the rotation direction of the crushing assembly 50 is greater than 0 degrees and less than 120 degrees. In this way, the spoiler effect of the spoiler claws 451 is better, and the crushing effect is better.

[0026] In some embodiments, the included angle R between the spoiler surfaces 452 and the rotation direction of the crushing assembly 50 can be 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, 90 degrees, 100 degrees, 110 degrees, 119 degrees, or a value between any two adjacent values.

[0027] The spoiler claws 451 extend downward and outward at an angle A between 30 degrees and 100 degrees with the horizontal direction. In this way, the spoiler effect of the spoiler claws 451 is better, and the crushing effect is better.

[0028] In some embodiments, the included angle A between the spoiler claws 451 and the horizontal direction can be 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, 90 degrees, 100 degrees, or a value between any two adjacent values.

[0029] In one embodiment, the spoiler 45 comprises a mounting sleeve 450 which cooperates with the housing 40, and at least two spoiler claws 451 extend downward and outward from the mounting sleeve 450. In this way, the assembly of the spoiler 45 is facilitated, and the spoiler 45 has a good spoiler effect. The number of the spoiler claws 451 can be two, three, four, five or six, and is not limited thereto. In other embodiments, the spoiler 45 and the housing 40 can be integrally formed.

[0030] In one embodiment, the spoiler 45 is detachably arranged at the bottom end of the housing 40. In another embodiment, the spoiler 45 is fixed at the bottom end of the housing 40. In this way, the structure is simple and the assembly is facilitated.

[0031] Referring to Figure 5 and Figure 6 , the spoiler claw 451 comprises a slot 453 arranged at the end. By arranging the slot 453 on the spoiler claw 451, the spoiler effect of the spoiler claw 451 is improved, so that the crushing effect of the crushing assembly 50 is better. The position, size and shape of the slot 453 can be arranged according to specific conditions, which are not limited herein.

[0032] Please continue to refer to Figure 5 and Figure 6 , the spoiler claw 451 comprises a rib 454 arranged in the slot 453. By arranging the rib 454 in the slot 453, the spoiler effect of the spoiler claw 451 is improved, so that the crushing effect of the crushing assembly 50 is better.

[0033] In the illustrated embodiment, the crushing assembly 50 comprises a rotating shaft 51 connected with the motor rotor 30 and a stirring blade 52 arranged at the bottom end of the rotating shaft 51, and the spoiler claw 451 is located outside the stirring blade 52. The stirring blade 52 can be fixed to the rotating shaft 51 by means of fasteners 56 or the like. In this way, the spoiler claw 451 plays a spoiler role outside the stirring blade 52, so that the crushing effect of the crushing assembly 50 is better. Specifically, the lower end of the rotor shell 31 is provided with a shaft seat 311, and the rotating shaft 51 is fixedly connected with the shaft seat 311. In another embodiment, the rotating shaft 51 is integrally formed with the rotor shell 31.
