[0023] The present invention is further described below in conjunction with specific embodiments and drawings.

[0024] See Figures 1 to 6 As shown, the present invention is a kitchen waste disposer, which mainly includes: a silo 1, a knife group 2, a drive motor 3 and a transmission assembly 4. Of course, in order to facilitate installation and protect the product, a shell 5 can be set outside the disposer.

[0025] The silo 1 is formed into a box shape with a hollow cavity 1 by an upper cover 101 and a lower cover 102, wherein a feed port 11 is provided on the top surface of the upper cover 101, and a discharge port 12 is provided on the side of the lower cover 102. The kitchen waste enters the silo 1 through the feed port 11, is crushed by the knife group 2 arranged in the silo 1, and is discharged through the discharge port 12. The upper cover 101 and the lower cover 102 can be fixed by screws. In addition, a water inlet 14 is also provided on the upper cover 101, and waste water generated in the kitchen can enter the cavity 1 of the silo 1 through the water inlet 14. The water inlet 14 has two functions: first, it can be used to discharge kitchen waste water, or as a water outlet for external equipment such as a dishwasher. Second, after the waste water enters the silo 1, it has a flushing effect on the crushed kitchen waste, which can accelerate the timely discharge of the crushed waste.

[0026] The knife group 2 mainly includes an outer knife disc 21 and an inner knife disc 22 which are arranged concentrically. The outer knife disc 21 and the inner knife disc 22 are superimposed on each other and driven by a transmission assembly 4 to realize forward and reverse relative rotation. The upper end surfaces of the outer knife disc 21 and the inner knife disc 22 are respectively formed with mutually matching knife teeth.

[0027] The main body of the outer cutter disc 21 is in the shape of a disc, and composite cutter teeth are formed at the edge of the upper end surface of the outer cutter disc 21. The composite cutter teeth include: outer cutter teeth 211 located on the outer circle and inner cutter teeth 212 located on the inner circle, wherein the outer cutter teeth 211 and the inner cutter teeth 212 are staggered with each other.

[0028] The main body of the inner blade disc 22 is also in the shape of a disc, and at least two cutting teeth 221 cooperating with the inner teeth 212 are formed on the edge of the upper end surface of the inner blade disc 22, that is, the outer diameter of the inner blade disc 22 just matches the inner diameter surrounded by the inner teeth 212 in the outer blade disc 21. At the same time, the composite teeth formed on the upper end surface of the outer blade disc 21 correspond in height to the cutting teeth 221 on the inner blade disc 22.

[0029] Since the feed port 11 is located above the central area of ​​the inner blade disc 22, in order to ensure safety in use, the diameter of the feed port 11 is smaller than the diameter of the cutting teeth 221 on the inner blade disc 22. In this way, even if the user accidentally puts his hand into the silo 1, the position he directly touches is the central area of ​​the inner blade disc 22, and the inner and outer teeth and cutting teeth used for crushing are all on the outer edge and cannot cause harm to the hand.

[0030] Similarly, since the feed port 11 is located above the center area of ​​the inner blade disc 22, when the food waste enters, it will directly fall into the center area of ​​the inner blade disc 22, and then the food waste will be thrown to the surroundings by centrifugal force, and cut and crushed by the blade teeth. In order to better guide the food waste, the center area of ​​the upper end surface of the inner blade disc 22 is formed with a spiral guide block 222. Figure 5 As shown, in this embodiment, two centrally symmetrical spiral guide blocks 222 are formed on the upper end surface of the inner cutter disc 22. The spiral guide blocks 222 are sharp-angled with a certain spiral curvature, and their tips point to the edge of the inner cutter disc 22. At the same time, the spiral guide blocks 222 have a curved surface. In addition, a protrusion 223 is also formed on the upper end surface of the inner cutter disc 22.

[0031] The circumferential surface of the outer cutter disc 21 is formed with at least one circle of horizontal cutter teeth 213. In this embodiment, two circles of horizontal cutter teeth 213 are provided, and the two circles of horizontal cutter teeth 213 are provided in parallel up and down, and the tips of the cutter teeth point to the outside.

[0032] The knife set 2 further includes a knife barrel 23 disposed outside the outer knife disc 21, the inner diameter of the knife barrel 23 corresponds to the outer diameter of the outer knife disc 21, and a through hole 231 is provided on the circumferential surface of the knife barrel 23. The inner wall of the knife barrel 23 will move relative to the side of the outer knife disc 21, thereby forming a cutting and crushing effect, further crushing the kitchen waste, and the crushed kitchen waste will pass through the through hole 231 and fall downward into the space below the outer knife disc 21. At the same time, during the downward feeding process of the kitchen waste, the horizontal blade teeth 213 disposed on the outer knife disc 21 will further crush the kitchen waste together with the inner wall of the knife barrel 23.

[0033] The knife barrel 23 is formed with a locking protrusion 232, and the inner wall of the lower cover 12 of the silo 1 is provided with a locking groove 13 that cooperates with the locking protrusion 232. The knife barrel 23 is installed in the lower cover 12 of the silo 1 through the locking cooperation between the locking protrusion 232 and the locking groove 13.

[0034] In addition, the knife assembly 2 further includes a lower blade 24, which is located below the outer knife disc 21 and driven by the transmission assembly 4. The lower blade 24 not only has a cutting function, but also has a spiral propulsion function. Through the rotation of the lower blade 24, the kitchen waste collected below the outer knife disc 22 is pushed forward and discharged from the discharge port 12.

[0035] In the present invention, the diameters of the outer blade disc 21, the horizontal blade teeth 213, and the lower blade disc 24 in the blade assembly 2 are equivalent to the inner wall diameter of the blade cylinder 23 to ensure that the kitchen waste can be completely crushed.

[0036] The knife group 2 is linked with the driving motor 3 through the transmission assembly 4 to achieve relative rotation. The transmission assembly 4 includes: a concentric double shaft consisting of a sleeve shaft 41 and an inner shaft 42, and a direction-changing gear box 43. The sleeve shaft 41 and the inner shaft 42 are linked through the direction-changing gear box 43 to change the rotation direction.

[0037] The lower end of the inner shaft 42 is linked to the drive motor 3, and the upper end thereof is connected to the inner cutter disc 22. The sleeve shaft 41 is sleeved outside the inner shaft 42 and connected to the outer cutter disc 21; the lower blade 24 is also fixed on the sleeve shaft 41 and operates synchronously with the outer cutter disc 22.

[0038] During operation, the driving motor 3 drives the inner cutter disc 22 to rotate forwardly through the inner shaft 42, and the inner shaft 42 drives the sleeve shaft 41 to rotate reversely through the direction-changing gear box 43, and simultaneously drives the outer cutter disc 21 and the lower blade 24 to rotate reversely.

[0039] The direction-changing gearbox 43 can be any direction-changing gearbox. Figure 7As shown, this is a schematic diagram of one embodiment of a direction-changing gearbox, which includes: an outer gear 431 fixed to the sleeve shaft 41, an inner gear 432 fixed to the inner shaft 42, an intermediate gear 433 and a double gear 434, wherein; the inner gear 432 is meshed with the intermediate gear 433, the intermediate gear 433 is meshed with one of the gears in the double gear 434, and the other gear in the double gear 434 is meshed with the outer gear 431. During operation, the driving motor 3 drives the inner cutter disc 22 to rotate in the forward direction through the inner shaft 42, and the inner gear 432 on the inner shaft 42 drives the intermediate gear 433 to rotate. The intermediate gear 433 is meshed with one of the gears in the double gear 434, so the double gear 434 starts to rotate and drives the outer gear 431 on the sleeve shaft 41 to rotate, thereby driving the sleeve shaft 41 and the outer cutter disc 21 and the lower blade 24 fixed on the sleeve shaft 41 to rotate, and at this time, the rotation direction of the sleeve shaft 41 is opposite to the rotation direction of the inner shaft 42.

[0040] Since the present invention is usually installed at the drain outlet of a kitchen sink, in order to protect the entire mechanism, the kitchen waste disposer further includes a housing 5, and the silo 1, the drive motor 3 and the transmission assembly 4 are covered in the housing 5. The knife group 2 is installed in the silo 1, the drive motor 3 is located outside the silo 1, and the transmission assembly 4 is connected between the drive motor 3 and the knife group 2.

[0041] Combination Figure 1 , 2 As shown in Figures 3 and 4, the shell 5 includes an upper shell 51 and a lower shell 52. The upper and lower shells 51 and 52 can be fixed by threaded connection. An upper through hole 511 corresponding to the feed port 11 is opened on the top surface of the upper shell 51, and side through holes corresponding to the discharge port 12 and the water inlet 14 are opened on the side of the upper shell 51.

[0042] The working principle of the present invention is as follows: the present invention is installed below the drain outlet of the kitchen sink, the drain outlet of the sink is docked with the feed inlet 11, and the discharge outlet 12 is connected to the sewage outlet. If a dishwasher is installed in the kitchen, the drain outlet of the dishwasher can be docked with the water inlet 14 of the present invention. During operation, the kitchen waste in the sink will enter the cavity 1 of the silo 1 through the feed inlet 11 and fall onto the inner cutter disc 22. At this time, the inner and outer cutter discs 22 and 21 rotate relative to each other, and the kitchen waste moves around along the spiral guide block 222 under the action of the release force, and the mutual operation of the cutting teeth 221, the inner teeth 212, and the outer teeth 211 forms a pulling, cutting, and crushing effect. Due to the end face molding adopted by the cutting teeth 221, the inner teeth 212, and the outer teeth 211, the teeth are relatively strong and can withstand greater impact, so even harder garbage such as meat and bones can be crushed.

[0043] The pulverized kitchen waste will run downward through the through hole 231 on the knife barrel 23 (the kitchen waste contains a lot of water, so the pulverized kitchen waste is a fluid), and the inner wall of the knife barrel 23 will move relative to the side of the outer knife disc 21, thereby forming a cutting and pulverizing effect, further pulverizing the kitchen waste, and the pulverized kitchen waste will pass through the through hole 231 and fall downward into the space below the outer knife disc 21. At the same time, during the downward feeding of the kitchen waste, the horizontal blade teeth 213 provided on the outer knife disc 21 will further pulverize the kitchen waste with the inner wall of the knife barrel 23. When the kitchen waste is transported to the bottom of the outer knife disc 21, the lower blade 24 has a spiral propulsion function, and the kitchen waste collected under the outer knife disc 22 is pushed forward by the rotation of the lower blade 24 and discharged from the discharge port 12.

[0044] The present invention uses end face blades to crush garbage by centrifugal force, and the end face blades are located at the edge of the blade disc, which ensures the safety of the user and prevents accidents. At the same time, the whole structure is stable and the operation is stable without running jitter and high noise.

[0045] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. All equivalent changes or modifications made according to the structure, characteristics and principles described in the patent application scope of the present invention should be included in the patent application scope of the present invention.
