[0001] The utility model belongs to the technical field of garbage disposal, and in particular relates to a grinding structure for a kitchen waste disposer and a kitchen waste disposer. Background Art

[0002] In order to improve the fineness and pulverizing speed of shredded garbage, existing food waste disposers mostly achieve this by increasing the power and rotation speed of driving mechanisms such as motors, and improving the structure of pulverizing parts such as grinding discs.

[0003] For example, the Chinese utility model patent "A grinding system for a kitchen waste disposer" with patent number 202320967186.2 and authorization announcement number CN219690666U includes a grinding cover with a grinding ring and a grinding disc installed in the grinding cover. The grinding disc rotates relative to the grinding ring under the drive of a driving mechanism. A grinding disc is fixed to the bottom of the grinding disc. A first curved portion with an opening facing upward is formed on the outer periphery of the grinding disc. The first curved portion extends outward from the outer edge of the grinding disc. The lower part of the grinding ring extends into the first curved portion with a gap left. A first blanking hole is opened on the first curved portion, thereby increasing the grinding area and effectively improving the grinding effect. Utility Model Content

[0004] The first technical problem to be solved by the utility model is to provide a grinding structure for a kitchen waste disposer in view of the current status of the prior art, so as to simplify the structure while ensuring the grinding effect.

[0005] The second technical problem to be solved by the utility model is to provide a kitchen waste disposer with the above-mentioned grinding structure.

[0006] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a grinding structure for a kitchen waste disposer, comprising:

[0007] a first grinding disc;

[0008] A driving mechanism, whose output end acts on the first grinding disc to drive the first grinding disc to rotate around its own axis extending up and down;

[0009] It is characterized by also including:

[0010] The first blade is vertically arranged below the first grinding disk and can rotate with the first grinding disk. The first blade extends radially along the first grinding disk, and at least a portion of the upper edge of the first blade close to the side of the first grinding disk is serrated and spaced from the lower surface of the first grinding disk to form a gap.

[0011] Therefore, when the driving mechanism drives the first grinding disc to rotate, the first blade rotates with the first grinding disc, and the serrated upper edge of the first blade can cut long strips of food waste such as fibers, and other parts of the first blade can grind and crush the food waste to ensure the treatment effect. At the same time, when the vertical part rotates with the first grinding disc, it can disturb the rotation of the fluid in the grinding chamber in the food waste disposer, thereby flushing the inner wall of the grinding chamber to achieve self-cleaning. At the same time, the rotating fluid can achieve strong drainage and increase the drainage speed.

[0012] Moreover, the utility model has a simple structure and is easy to implement.

[0013] Preferably, there are at least two first blades, which are arranged at intervals along the circumference of the first grinding disk.

[0014] Preferably, the first blade is located at the inner periphery of the side of the first grinding disk.

[0015] Further, the side edge of the first grinding disc is a tooth-shaped body with concave and convex parts alternately arranged circumferentially;

[0016] At least a portion of the serrated upper edge of the first blade is opposite to the teeth on the side of the first grinding disk.

[0017] When the teeth rotate, they can cut the long fibers in the kitchen waste, further improving the crushing effect. The cut waste passes through the gaps between the teeth and moves downward to the top of the first blade, and the serrated upper edge of the first blade can further cut and grind this part of the waste, improving the grinding effect.

[0018] In the above schemes, preferably, it further comprises an annular body arranged around the axis, arranged below the first grinding disc and located at the inner periphery of the side of the first grinding disc, and constrained together with the first grinding disc;

[0019] The first blade is connected to the annular body, and the serrated upper edge of the first blade extends outward relative to the outer periphery of the annular body.

[0020] Preferably, the first blade is integrally connected to the annular body.

[0021] Furthermore, the annular body is provided with a second blade which is vertically arranged and radially extends;

[0022] A first through hole is provided on the first grinding disc at a position corresponding to the second blade, and the second blade is located above the first grinding disc after passing through the first through hole.

[0023] The design of the first perforation allows the second blade to pass through while also stabilizing the structure of the second blade to prevent the second blade from accidentally bending.

[0024] A second blade is arranged on the annular body, and the second blade passes through the first through hole on the first grinding disc and is located above the first grinding disc. When the driving mechanism drives the first grinding disc to rotate, the second blade above the first grinding disc can grind and crush the kitchen waste to ensure the processing effect.

[0025] To simplify the structure, preferably, the annular body has a tongue piece with a flanged edge at its outer periphery, and the bent tongue piece is the second blade, and the first strip hole and the second strip hole are formed by the flanged edge bending of the tongue piece, wherein:

[0026] A first strip hole extends from the outer periphery of the annular body toward the center, and an outer end of the first strip hole opens at the outer periphery of the annular body;

[0027] The second strip-shaped hole extends from the inner end of the first strip-shaped hole and forms an L-shaped arrangement together with the first strip-shaped hole.

[0028] That is, the second blade of the utility model is connected to the annular body as a whole. In addition, the second blade can also be an independent component, connected to the annular body by connecting members such as screws.

[0029] Furthermore, it also includes a second grinding disc, which is horizontally placed above the first grinding disc and can rotate together with the first grinding disc under the drive of the driving mechanism. The second grinding disc is provided with a second through hole penetrating the wall thickness thereof for the second blade to pass through.

[0030] Preferably, a grinding hammer is provided on the upper surface of the second grinding disc. The design of the grinding hammer and the second blade can further improve the grinding and crushing effect of the kitchen waste.

[0031] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: a kitchen waste disposer, characterized by having the grinding structure as described above.

[0032] Preferably, the food waste disposer also includes:

[0033] A grinding cover, wherein the interior is hollow and a grinding chamber is formed, in which the grinding disc and the blades are arranged, wherein the upper part of the grinding chamber has a feed inlet, and the lower part of the grinding chamber has a discharge outlet;

It has a first ring wall vertically arranged on the periphery of the grinding disk, and a second ring wall folded inward from the lower edge of the first ring wall. The inner edge of the second ring wall is in a tooth shape with concave and convex parts alternately arranged circumferentially, and extends into the gap.

[0035] Compared with the prior art, the utility model has the following advantages: when the driving mechanism drives the first grinding disc to rotate, the first blade rotates with the first grinding disc, the serrated upper edge of the first blade can cut long strips of kitchen waste such as fibers, and other parts of the first blade can grind and crush the kitchen waste to ensure the treatment effect. At the same time, when the vertical part rotates with the first grinding disc, it can disturb the rotation of the fluid in the grinding chamber in the kitchen waste disposer, thereby flushing the inner wall of the grinding chamber to achieve self-cleaning.

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0044] like Figures 1 to 6 As shown, a grinding structure for a food waste disposer and a preferred embodiment of the food waste disposer of the present invention are shown. The food waste disposer includes a grinding cover 1, a grinding structure, a grinding ring 3, and a valve plate 861.

[0045] The grinding cover 1 has a grinding chamber 10 inside, a feed port 10a and a water inlet 10c are provided at the upper part of the grinding chamber 10, and a discharge port 10b is provided at the side wall of the lower part of the grinding chamber 10. The edge of the discharge port 10b extends outward relative to the side wall of the grinding chamber 10. The feed port 10a is located at the top of the grinding chamber 10, the water inlet 10c is located below the feed port 10a, and a solenoid valve is provided at the water inlet 10c.

[0046] The grinding structure includes a first grinding disc 21, a second grinding disc 22, a driving mechanism 200 and a blade assembly. The first grinding disc 21 and the second grinding disc 22 are placed horizontally in the grinding chamber 10, below the water inlet 10c and above the discharge port 10b, and the two are arranged coaxially. At the same time, a grinding hammer 221 is provided on the upper surface of the second grinding disc 22. The side edge of the first grinding disc 21 is located circumferentially on the periphery of the side surface of the second grinding disc 22, and is a toothed body with concave and convex parts alternately arranged circumferentially.

[0047] The driving mechanism 200 is a motor, and the output shaft of the motor acts on the first grinding disc 21 and the second grinding disc 22 to drive the first grinding disc 21 and the second grinding disc 22 to rotate around their own vertically extending axes.

[0048] The blade assembly includes an annular body 230 , a first blade 231 and a second blade 232 .

[0049] The annular body 230 is disposed around the axis below the first grinding disc 21 and located at the inner periphery of the side of the first grinding disc 21 , and is connected to the first grinding disc 21 by screws.

[0050] The first blade 231 is vertically disposed on the lower surface of the annular body 230 and can rotate with the first grinding disc 21. The first blade 231 extends along the radial direction of the annular body 230. At least a portion of the upper edge of the first blade 231 close to the side of the first grinding disc 21 is serrated and spaced from the lower surface of the first grinding disc 21 to form a gap 201. At least a portion of the serrated upper edge of the first blade 231 is opposite to the teeth on the side of the first grinding disc 21. At the same time, the serrated upper edge of the first blade 231 extends outward relative to the outer periphery of the annular body 230.

[0051] In this embodiment, there are multiple first blades 231, and they are arranged at intervals along the circumference of the annular body 230. And each first blade 231 is connected to the annular body 230 as a whole. Specifically: the annular body 230 has a flap with a flanged bend at its outer periphery, and the bent flap extends downward relative to the annular body 230 to form the first blade 231, and at least the lower part of the first blade 231 is arranged corresponding to the discharge port 10b. At the same time, due to the flanged bend of the flap, a T-shaped hole 235 is formed. The longitudinal strip part of the T-shaped hole 235 extends from the outer periphery of the annular body 230 to the center, and the outer end of the longitudinal strip part opens at the outer periphery of the annular body 230; the transverse strip part of the T-shaped hole 235 is arranged corresponding to the inner end of the longitudinal strip part. In this way, a single T-shaped hole 235 can be flanged and bent to form two first blades 231. There are at least two T-shaped holes 235 in this embodiment, and they are arranged at intervals along the circumference.

[0052] The second blades 232 are vertically arranged on the upper surface of the annular body 230 and can rotate with the first grinding disc 21. There are two second blades 232, which are arranged at intervals along the circumference of the annular body 230 and extend along the radial direction of the annular body 230. The first grinding disc 21 is provided with a first through hole 210 at a position corresponding to each second blade 232, and the second grinding disc 22 is provided with a second through hole 220 penetrating through the wall thickness thereof at a position corresponding to each second blade 232. The second blades 232 pass through the first through hole 210 and the second through hole 220 in sequence and are located above the second grinding disc 22.

[0053] In this embodiment, each second blade 232 is connected to the annular body 230 as a whole. Specifically, the annular body 230 has a tongue piece with a flanged bend at its outer periphery, and the bent tongue piece is the second blade 232. At the same time, the flanged bend of the tongue piece also forms a first strip hole 233 and a second strip hole 234, wherein: the first strip hole 233 extends from the outer periphery of the annular body 230 to the center, and the outer end of the first strip hole 233 opens to the outer periphery of the annular body 230; the second strip hole 234 extends from the inner end of the first strip hole 233 and forms an L-shaped arrangement together with the first strip hole 233. In this embodiment, each second blade 232 is arranged to avoid the first blade 231.

[0054] The above-mentioned grinding ring 3 is located in the grinding chamber 10 and fixed relative to the grinding chamber 10. It has a first ring wall 31 vertically arranged on the periphery of the grinding disk, and a second ring wall 32 folded inward from the lower edge of the first ring wall 31. The inner edge of the second ring wall 32 is in a tooth shape with alternating concave and convex parts arranged circumferentially, and extends into the gap 201.

[0055] The valve plate 861 is located outside the discharge port 10b, and at least the lower side of the valve plate 861 is provided with a counterweight 862, and the upper side of the valve plate 861 is rotatably constrained to the discharge port 10b. Under the gravity of the counterweight 862, the valve plate 861 always has a tendency to rotate downward so that the surface of the valve plate 861 fits the edge of the discharge port 10b, and when the surface of the valve plate 861 fits the edge of the discharge port 10b (that is, the valve plate 861 horizontally blocks the discharge port 10b), the surface of the valve plate 861 tilts outward from top to bottom, and the angle θ between the surface of the valve plate 861 and the vertical plane is ≤60°. At the same time, the valve plate 861 is arranged to overcome the gravity of the counterweight 862 and rotate upward to open the discharge port 10b under the action of the fluid disturbed by the blade 23 in the pulverizing chamber 10.

[0056] In the natural state, the valve plate 861 rotates downward under the action of the gravity of the counterweight block 862 and blocks the discharge port 10b horizontally. At this time, the water flow entering from the water inlet 10c accumulates in the grinding chamber 10 (that is, the water inlet speed is greater than the water discharge speed). Then the driving mechanism 200 works to drive the grinding disc and the blade assembly to rotate. The rotating grinding disc and the first blade 231 can disturb the fluid in the grinding chamber to rotate together, thereby flushing the inner wall of the grinding chamber to achieve self-cleaning. At the same time, the rotating fluid can apply pressure to the valve plate 861, so that the valve plate 861 overcomes the gravity of the counterweight block 862 and rotates upward to open the discharge port, so that the fluid is discharged from the discharge port together with the cleaned residue.

[0057] The steps of the self-cleaning method of this embodiment are as follows:

[0058] 1. The driving mechanism 200 stops working, and water enters the water inlet 10c, so that water is stored in the grinding chamber 10, and the water level is above the grinding disc;

[0059] Second, the driving mechanism 200 drives the grinding disc and the blade assembly to rotate, so as to disturb the fluid to rotate and flush the inner wall surface of the grinding chamber 10. At the same time, the fluid opens the valve plate 861 and discharges the flushed residue from the discharge port 10b.

[0060] 3. When the driving mechanism running time reaches t1, water inlet 10c stops entering, and driving mechanism 200 continues to drive the grinding disc and blade assembly to rotate for t2 and then stops working, wherein t1≤30s, t2≤10s.

[0061] During the grinding operation, the driving mechanism 200 drives the grinding disc and the blade assembly to rotate. The kitchen waste entering from the feed port is ground and crushed by the grinding hammer 211, the second blade 232, and the first and second grinding discs, and then passes through the first blade 231. It is further cut and crushed under the action of the upper edge of the first blade 231 and the second ring wall 32 of the grinding ring, thereby improving the grinding and crushing effect.

Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0063] The term "vertical" is also used in the specification and claims of the present utility model, which means basically along the up and down direction, and is not limited to the vertical direction only, and can also be slightly inclined relative to the vertical direction.

[0064] The term "radial" is also used in the specification and claims of the present utility model, which means basically along the inward and outward direction, and is not limited to the radial direction passing through the center of the circle, and can also be slightly deviated from the radial direction.
