A thrust bearing 26 is arranged in the middle of the cutterhead 23, and an output shaft 221 of the motor 22 passes through the middle of the thrust bearing 26, so that the output shaft 221 and the cutterhead 23 can rotate relatively. The thrust bearing 26 includes a bearing main body 261, a bearing lower cover 262 disposed below the bearing main body 261, and a bearing upper cover 263 disposed above the bearing main body 261. The top surface of the bearing upper cover 263 of the thrust bearing 26 is slightly higher than the top surface of the cutterhead 23, and the cutter 24 is pressed against the thrust bearing 26. The cutter 24 includes a cutter table 241 in the middle and blades 242 connected to both sides of the blade connecting portion 241, and the cutter table 241 has a circular shape having a diameter corresponding to the thrust bearing 26 and is pressed against the bearing upper cover 263 of the thrust bearing 26. The arrangement of the thrust bearing 26 can control the concentricity and coaxiality of the output shaft 221 of the motor 22, and avoid the left and right shaking of the cutter disc 23 and the cutting piece 24, thereby influencing the cutting effect. The blades 242 extend symmetrically away from each other from the outer periphery of the table 241. The side of each blade 242 (having two and opposite) extending gradually away from the table 241 by the outer periphery of the table 241 has a first blade 2421 at the bottom end and a second blade 2422 at the top end, see fig. 7.

Referring to fig. 4 to 6 and 8, the stirring member 25 includes a centrally located vane shaft 251 and a first vane 252 disposed outside the vane shaft 251, and the stirring member 25 extends partially upward into the slag basket 1. The blade shaft 251 has a hollow cylindrical shape, abuts against the top of the table 241 of the cutter 24, and the output shaft 221 of the motor 22 penetrates into the blade shaft 251 and is connected thereto. Screws may be inserted into the top of the output shaft 221 of the motor 22 to connect the output shaft 221 and the stirring member 25, and also to compress the cutting member 24 against the cutterhead 23, so as to prevent the cutting member 24 from moving up and down relative to the cutterhead 23. The first blades 252 may have two, are disposed on the outer circumferential wall of the blade shaft 251, and are symmetrically arranged. The first blade 252 may be configured as an axial flow blade of an existing axial flow impeller for stirring and also for cutting during residue disposal.

Referring to fig. 9, the cutter head 23 includes a circular cutter head body 231, a boss 232 provided at a position near an edge of the cutter head body 231, a first drain hole 233 and a screw hole 234 provided on the cutter head body 231. Since the output shaft 221 of the motor 22 passes upward through the cutter head body 231, the cutter table 241 and the vane shaft 251, the cutter table 241, the vane shaft 251 and the cutter head body 231 are coaxially disposed, and the center of the cutter table 241 and the center of the cutter head body 231 are located on the same vertical line. The thrust bearing 26 is provided in the middle of the cutter body 231.

The bosses 232 may have four, circumferentially spaced apart on the cutterhead body 231, each boss 232 extending upwardly a distance from the upper surface of the cutterhead body 231. The distance from the outer end of the blade 242 of the cutter 24, which is far from the table 241, to the center of the table 241 is smaller than the distance from the inner side of the boss 232 to the center of the cutter head body 231, so that when the cutter 24 rotates, the outer end of the blade 242 is located radially inward of the boss 232 with a certain interval therebetween when it is rotated to be opposite to the boss 232, so that food waste is cut in the interval. The first leakage holes 233 have a plurality of triangular shapes in this embodiment. The cutter body 231 is further formed with a drain groove 235, and the drain groove 235 is formed by downwardly recessing the upper surface of the cutter body 231. In the present embodiment, the drain grooves 235 may have four, and each of the drain grooves 235 is elongated, each drain groove 235 being arranged along the radial direction of the cutterhead body 231, the four drain grooves 235 being uniformly arranged at intervals in the circumferential direction. A second drain hole 2351 is formed in each drain groove 235.

A flat head screw can be arranged in the screw hole 234 to connect and fix the cutter head 23 and the volute 27, and the flat head screw ensures that the screw head is flush with the upper surface of the cutter head 231, so that the cutter blade 242 is prevented from being damaged due to collision.

Referring to fig. 10, the impeller 21 includes a plurality of second blades 211, and a certain interval is provided between the top of the second blades 211 and the cutter head body 231, and each second blade 211 is provided with a third blade 212 near the top of the cutter head body 231, thereby performing a cutting function while accelerating the outflow of water.

When the residue is processed, after the food residue leaks from the residue basket 1 into the residue crushing assembly 2, the motor 22 drives the impeller 21, the cutting member 24 and the stirring member 25 to rotate along the first direction (anticlockwise in the embodiment), the food residue with larger friction between the first edge 2421 of the blade 242 of the cutting member 24 and the cutter head main body 231 of the cutter head 23 is crushed by the friction between the first leakage holes 233 and the cutter head 23, in addition, the residue is crushed by the shearing force generated between the second edge 2422 of the blade 242 and the top of the boss 232 on the cutter head 23, the shearing is mainly aimed at the residue with better toughness of the Chinese chives, so that the strip-shaped residue which can prevent the stirring of the blade 242 can be sheared out in the leakage grooves 235 of the cutter head 23, the effect of preventing the blade 242 from being blocked is achieved, and the smaller residue in the leakage grooves 235 can be leaked to the lower part of the cutter head 23 through the second leakage holes 2351; at the same time, the third blade 212 on the second blade 211 of the impeller 21 can also cooperate with the cutterhead 23 to cut the residue that leaks between the cutterhead 23 and the impeller 21, the residue is cut more and crushed, the cut residue is discharged from the volute 27 into the drain, and during this process the first blade 242 of the agitator 24 also has a certain cutting capacity. The motor 22 may be programmed with a protective function, and when the motor 22 rotates the cutter 24, and encounters a hard residue, and the residue cannot be cut, the protective mode is turned on, the output shaft 221 rotates clockwise by an angle, and then rotates counterclockwise, so as to avoid the phenomenon that the motor 22 is blocked.

When a lot of food residues remain in the residue basket 1 after the sink or the dish washer is used for a long time, such as oil and the like of chafing dish, self-cleaning is started, at this time, the motor 22 is operated to drive the impeller 21, the cutting member 24 and the stirring member 25 to rotate in a second direction (clockwise in this embodiment) opposite to the first direction, the stirring member 25 stirs the water discharged from the sink 100 and then upwards surges, and the residue basket 1 forms water flow impact, and the residues on the residue basket 1 are cleaned by the upwards surge of the water flow.
