Description

Technical Field

[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] A blade is disposed below the first grinding disc and is constrained together with the first grinding disc, and the blade has:

[0011] A transverse portion extending radially along the lower surface of the first grinding disc, wherein at least a portion of the transverse portion is located at the periphery of the side edge of the first grinding disc to form a convex tooth;

[0012] A vertical portion extending downward relative to the horizontal portion.

[0013] Therefore, when the driving mechanism drives the first grinding disc to rotate, the convex teeth on the horizontal part and the vertical part of the blade can grind and crush the food waste to ensure the processing 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 crushing chamber in the food waste disposer, thereby flushing the inner wall of the crushing chamber to achieve self-cleaning, and at the same time, the rotating fluid can achieve strong drainage and increase the drainage speed.

[0014] Moreover, the utility model has a simple structure and is easy to implement.

[0015] Preferably, the vertical portion is located at the inner periphery of the side of the first grinding disc and extends along the radial direction of the first grinding disc, so as to better disturb the rotation of the fluid.

[0016] Preferably, the blade further has an annular body arranged around the axis, the annular body is located at the inner periphery of the side of the first grinding disk and is constrained together with the first grinding disk, and the transverse portion and the vertical portion are both arranged on the annular body.

[0017] Preferably, there are at least two vertical portions, which are arranged on the annular body at intervals along the circumferential direction.

[0019] Furthermore, the annular body is integrally connected with the vertical portion.

[0020] Furthermore, the annular body has a folded piece at its outer periphery, and the folded piece extends downward relative to the annular body to form the above-mentioned vertical portion. At the same time, a T-shaped hole is formed due to the folded edge of the folded piece. The longitudinal bar portion of the T-shaped hole extends from the outer periphery of the annular body to the center, and the outer end of the longitudinal bar portion opens to the outer periphery of the annular body; the transverse bar portion of the T-shaped hole is arranged corresponding to the inner end of the longitudinal bar portion.

[0021] Since the vertical portion is integrally formed on the annular body, the structure is simplified and the cost is reduced.

[0022] Furthermore, there are at least two T-shaped holes, which are arranged on the annular body at intervals along the circumferential direction.

[0023] In the above solution, preferably, the transverse portion extends radially outward from the outer periphery of the annular body.

[0024] Preferably, there are at least two transverse portions, which are arranged at intervals along the circumferential direction.

[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] By providing a tongue with a flanged and bent edge at the periphery of the first grinding disc, and the bent tongue extends upward relative to the upper surface of the first grinding disc, when the driving mechanism drives the first grinding disc to rotate, the tongue on the first grinding disc can grind and crush the kitchen waste to ensure the processing effect; at the same time, since the tongue is integrally formed on the first grinding disc, the structure is simplified and the cost is reduced.

[0029] Preferably, a second grinding disc is further included, which is placed horizontally 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 through hole that penetrates the wall thickness thereof, so as to allow the bent tongue to pass through. The design of the through hole on the second grinding disc can not only allow the tongue to pass through, but also stabilize the structure of the tongue to prevent the tongue from being accidentally bent.

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

[0031] Preferably, the bent tongue extends in the radial direction of the first grinding disk.

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0046] 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 crushing cover 1, a grinding structure and a valve plate 861.

[0047] The crushing cover 1 has a crushing chamber 10 inside, a feed port 10a and a water inlet 10c are provided at the upper part of the crushing chamber 10, and a discharge port 10b is provided at the side wall of the lower part of the crushing chamber 10. The edge of the discharge port 10b extends outward relative to the side wall of the crushing chamber 10. The feed port 10a is located at the top of the crushing chamber 10, the water inlet 10c is located below the feed port 10a, and a solenoid valve is provided at the water inlet 10c.

[0048] The grinding structure includes a first grinding disc 21, a second grinding disc 22, a driving mechanism 200 and blades 23. The first grinding disc 21 and the second grinding disc 22 are horizontally placed in the grinding chamber 10, below the water inlet 10c and above the discharge port 10b, and the two are coaxially arranged.

[0049] Furthermore, the first grinding disc 21 has a tongue piece 210 with a flanged bend at its periphery, and the bent tongue piece 210 extends upward relative to the upper surface of the first grinding disc 21, and the upward extension length is 1 to 15 mm (the upward extension length can be any value between 1 and 15 mm, such as 1 mm, 5 mm, 10 mm, 15 mm, etc.), and the bent tongue piece 210 extends radially along the first grinding disc 21. In addition, due to the flanged bend of the tongue piece 210, a first strip hole 211 and a second strip hole 212 are formed, wherein: the first strip hole 211 extends from the periphery of the first grinding disc 21 to the center, and the outer end of the first strip hole 211 opens at the periphery of the first grinding disc 21; the second strip hole 212 extends from the inner end of the first strip hole 211 and forms an L-shaped arrangement together with the first strip hole 211. In this embodiment, there are two tongue pieces 210, which are arranged on the first grinding disc 21 at equal intervals along the circumferential direction. Meanwhile, the periphery of the first grinding disc 21 is a tooth-shaped body with concave and convex parts arranged alternately on the periphery. The periphery of the first grinding disc 21 forms notches 213 of the tooth-shaped body at the positions corresponding to the tongue pieces 210 .

[0050] The second grinding disc 22 is horizontally placed above the first grinding disc 21 and is coaxially arranged with the first grinding disc 21, and a grinding hammer 221 is arranged on the upper surface of the second grinding disc 22. The second grinding disc 22 is provided with a through hole 220 penetrating the wall thickness thereof at a position corresponding to each tongue piece 210, so that the corresponding bent tongue piece 210 can pass through.

[0051] The blade 23 is arranged below the first grinding disc 21 and is constrained together with the first grinding disc 21. The blade 23 has an annular body 230 arranged around the axis. The annular body 230 is 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. At the same time, the annular body 230 has a flanged and bent folded piece at its outer periphery, and the bent folded piece extends downward relative to the annular body 230 to form a vertical portion 232. The vertical portion 232 extends along the radial direction of the first grinding disc 21, and at least the lower part of the vertical portion 232 is arranged corresponding to the discharge port 10b. At the same time, due to the flanged bending of the folded piece, a T-shaped hole 233 is formed. The longitudinal strip portion of the T-shaped hole 233 extends from the outer periphery of the annular body 230 to the center, and the outer end of the longitudinal strip portion opens at the outer periphery of the annular body 230; the transverse strip portion of the T-shaped hole 233 is arranged corresponding to the inner end of the longitudinal strip portion. In this embodiment, there are at least two T-shaped holes 233, which are arranged at intervals along the circumferential direction on the annular body 230. In addition, the outer circumference of the annular body 230 is provided with a transverse portion extending radially outward at a position avoiding the folding sheet and corresponding to each notch 213, and the outer end of the transverse portion is located in the corresponding notch 213 to form a convex tooth 231.

[0052] 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.

[0053] 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.

[0054] Under 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 crushing 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 blades 23 to rotate. The rotating grinding disc and the blades 23 can disturb the fluid in the crushing chamber to rotate together, thereby flushing the inner wall of the crushing chamber to achieve self-cleaning. At the same time, the rotating fluid can apply a 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.

[0055] The steps of the self-cleaning method of this embodiment are as follows:

[0056] 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 located above the grinding element 2;

[0057] Second, the driving mechanism 200 drives the grinding disc and the blades 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 the flushed residue is discharged from the discharge port 10b;

[0058] 3. When the driving mechanism running time reaches t1, water inlet 10c stops inletting, and driving mechanism 200 continues to drive crushing element 2 to rotate for t2 and then stops working, wherein t1≤30s, t2≤10s.

[0059] In the specification and claims of the present invention, terms indicating directions, such as "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. 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, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0060] 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.

[0061] 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.
