[0001] The utility model relates to the technical field of food waste processors, and particularly to an integrated motor of a food waste processor. Background Art

[0002] The invention patent with the patent number 201720904782.2 discloses a driving direct current brushless motor for a food waste processor, which includes a motor body and a controller. The motor body and the controller are electrically connected through a phase wire cable, and there are three phase wires in the phase wire cable. The motor body is not provided with a position sensor. The motor body includes a front end cover equipped with a front bearing, a rear end cover equipped with a rear bearing, a stator assembly, a rotor assembly, and a motor shaft. Two ends of the stator assembly are respectively fixed to the front end cover and the rear end cover, and the outer surface of the stator assembly serves as the machine body.

[0003] There are certain defects in the disclosed content of this patent. The split structure of the motor and the driver will generate redundant parts. Placing the motor and the driver separately will occupy too much unnecessary space, increasing the requirements for the installation space and the overall machine cost. Assembling the motor and the driver separately increases the assembly steps, the process is slow, and the increase in man-hours leads to an increase in cost. Summary of the Invention

[0004] In view of the above technical problems, the utility model provides an integrated motor of a food waste processor, which integrates the motor and the drive board. On the premise of ensuring the performance of the motor, redundant parts are eliminated, the installation space is saved, the assembly efficiency is improved, and the installation cost is reduced.

[0017] The following further describes the embodiments of the present utility model in detail with reference to the drawings.

[0018] Figures 1 to 4 The structural schematic diagram of the present utility model is shown.

[0019] The reference numerals therein are: front end cover 1, stirring bin 1a, blade locking portion 1b, residue discharge port 1c, inner ring 1d, outer ring 1e, oil-impregnated bearing 2, motor housing 3, first screw 4a, second screw 4b, motor installation cavity 5, stator core 6, skeleton 7, rotating shaft 8, rotor magnetic ring 9, adjusting gasket 10, lower bearing 11, corrugated gasket 12, drive board 13, mounting housing 14, mounting seat 14a, plastic housing 14b, wire outlet 14c.

[0020] An integrated food waste processor motor of the present utility model includes a front end cover 1, a motor housing 3, a stator core 6, a rotating shaft 8, a rotor magnetic ring 9, a driving board 13, and a mounting housing 14. The motor and the driving board 13 are integrated into one, improving the assembly efficiency. The mounting seat 14a at the bottom of the mounting housing 14 dissipates the heat generated during the operation of the motor and the driving board 13, ensuring the stable operation of the motor.

[0021] As Figure 1 shown, inside the upper end of the front end cover 1, there is a cylindrical stirring chamber 1a. In the middle of the stirring chamber 1a, there is a blade locking part 1b, and on the side of the front end cover 1, there is a residue discharge port 1c. The front end cover 1 can be used both as the front end cover 1 of the motor and directly as the stirring chamber 1a of the food waste processor. Food residues are put into the stirring chamber 1a. After being crushed by the blades, the food residues are discharged from the residue discharge port 1c. Such a design reduces the number of parts, thereby achieving the purpose of cost reduction.

[0022] At the lower end of the front end cover 1, there is an oil-impregnated bearing 2. Compared with ball bearings, the oil-impregnated bearing 2 has a low price, a long service life, and low noise. The oil-impregnated bearing 2 is pressed into the bottom of the front end cover 1, and the oil-impregnated bearing 2 and the front end cover 1 are assembled into one, improving the assembly efficiency.

[0023] As Figure 2 shown, at the lower end of the front end cover 1, there are concentric inner ring 1d and outer ring 1e. At the lower end of the front end cover 1, there are a motor housing 3 and a mounting housing 14. The upper end of the motor housing 3 is fixedly connected to the inner ring 1d of the front end cover 1 through a first screw 4a, and the mounting housing 14 is fixedly connected to the outer ring 1e of the front end cover 1. As Figure 3 shown, between the inner ring 1d of the front end cover 1 and the inside of the motor housing 3, there is a motor installation cavity 5. Inside the motor installation cavity 5, there are installed a stator core 6, a skeleton 7, a rotor magnetic ring 9, and a rotating shaft 8. The stator core 6 is installed on the skeleton 7, the rotor magnetic ring 9 is sleeved on the rotating shaft 8, and the stator core 6 and the rotor magnetic ring 9 are assembled together. Since a regularly changing current passes through the stator core 6, the stator core 6 will generate an induced magnetic field. Driven by the induced magnetic field, the rotor magnetic ring 9 drives the rotating shaft 8 to rotate.

[0024] At the upper end of the rotating shaft 8, an adjusting gasket 10 is placed, passed through the oil-impregnated bearing 2 and assembled with the front end cover 1, and locked and assembled through a first screw 4a. At the upper end of the bottom of the motor housing 3, there is a lower bearing 11. The lower bearing 11 is pressed into the bottom of the motor housing 3, and there is a corrugated gasket 12 at the lower end of the lower bearing 11. The lower end of the rotating shaft 8 is connected to the lower bearing 11 and sleeved with the corrugated gasket 12 to prevent parts from loosening, completing the assembly of the motor part.

[0025] As Figure 4As shown, a drive board 13 is provided inside the installation housing 14. The drive board 13 is located at the lower end of the motor housing 3 and is used to control the motor speed and the opening and closing effect. The ends of the components on the drive board 13 are accommodated between the inner wall of the installation housing 14 and the outer wall of the motor housing 3, improving the space utilization rate inside the motor.

[0026] The installation housing 14 is composed of an installation base 14a at the bottom and a plastic housing 14b around it. The installation base 14a and the plastic housing 14b are combined into one by an injection molding process. An outlet 14c is provided on the plastic housing 14b, and the installation base 14a is made of a metal material. The plastic housing 14b around the installation housing 14 is used to protect the internal structure. The drive board 13 is fixed to the installation base 14a by a second screw 4b. The installation base 14a at the bottom of the installation housing 14 is covered with heat dissipation ribs, and the heat generated when the motor body and the drive board 13 work is dissipated through the metal installation base 14a to ensure the normal operation of the motor. Combining the assembled motor part with the assembled installation housing 14 part completes the integrated assembly of the food waste processor motor and the drive board 13.

[0027] The best embodiments of the present invention have been illustrated, and various changes or modifications made by those of ordinary skill in the art will not depart from the scope of the present invention.
