Description

Technical Field

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

[0002] Currently, the food waste disposers on the market are unable to completely discharge the food waste after processing it, resulting in some small residues remaining inside the machine. If the food waste disposer is not started for a long time or is used multiple times, the residues may rot and stink, resulting in a poor user experience.

[0003] To this end, the Chinese invention patent application "A Kitchen Waste Disposer" with application number 202210782652.X and publication number CN117344831A discloses a kitchen waste disposer, which includes a housing and a grinding cover installed inside the housing, a grinding disc is installed inside the grinding cover, and the grinding cover includes an upper grinding cover and a lower grinding cover, a feeding port is opened on the top of the upper grinding cover, a discharge port is opened on the lower grinding cover, an annular step portion is formed on the side wall of the upper grinding cover, and a grinding disc is installed inside the upper grinding cover. The grinding cover is provided with first water outlets spaced along the circumference, the first water outlets are arranged above the annular step portion, a second water outlet is arranged on the annular step portion, a water inlet cover is installed on the outer periphery of the upper grinding cover, the water inlet cover has a water inlet, a liquid separation cavity is formed between the water inlet cover and the upper grinding cover, the first water outlet is always connected with the water inlet through the liquid separation cavity, a liquid separation ring that can move up and down is installed in the liquid separation cavity, and the second water outlet is connected with or blocked by the up and down movement of the liquid separation ring. When the kitchen waste disposer is turned on, the liquid separation ring is in the lower position, and water flows out from the first water outlet to achieve the wall cleaning effect. When the kitchen waste is put into the grinding cavity, the liquid separation ring is pushed up by the effect of disturbing the food, and the water flow is also directly shot to the grinding working area through the second water outlet, which suppresses the ground food, enhances the disturbance, and increases the grinding effect.

[0004] Another example is the Chinese utility model patent "A kitchen waste treatment device" with patent number 202221360135.5 and announcement number CN218078151U, which includes a housing and a grinding cover, a grinding disc is installed inside the grinding cover, a feeding port is provided at the top of the grinding cover, a discharge port is provided at the bottom of the grinding cover, a fixed sprayer is installed inside the grinding cover, the fixed sprayer is arranged above the grinding disc, and water outlet holes distributed along the circumferential direction are opened on the fixed sprayer, a water inlet cavity is formed between the fixed sprayer and the inner wall of the grinding cover, a water inlet connected to the water inlet cavity is opened on the grinding cover, a rotating disk is installed in the water inlet cavity, and the rotating disk can rotate under the action of the water flow flowing in from the water inlet, and the rotation direction of the rotating disk is opposite to that of the grinding disk. When working, the water flow in the water inlet cavity produces a spraying effect through the water outlet hole on the fixed sprayer, and the water flow is directly sprayed on the grinding working area, stirring the kitchen waste and improving the grinding effect. At the same time, the spray water can also be sprayed onto the inner wall of the grinding cover to wash away the kitchen waste splashed onto the inner wall of the grinding cover by the grinding disc, thus achieving a self-cleaning effect.

[0005] Existing food waste disposers mostly achieve self-cleaning through spraying, their structures are relatively complex, and the cleaning effect needs to be further improved. Utility Model Content

[0006] The first technical problem to be solved by the utility model is to provide a kitchen waste disposer in view of the current status of the prior art, so as to facilitate the discharge of the kitchen waste after being crushed.

[0007] The second technical problem to be solved by the utility model is to provide a kitchen waste disposer to improve the garbage crushing effect.

[0008] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a kitchen waste disposer, comprising:

[0009] A crushing cover, which has a crushing chamber inside, a feed inlet and a water inlet are arranged at the upper part of the crushing chamber, and a discharge port is arranged on the side wall of the lower part of the crushing chamber;

[0010] A grinding disc is placed horizontally in the pulverizing chamber and is used to pulverize the garbage entering from the feed inlet;

[0011] A driving mechanism, whose output end acts on the grinding disc to drive the grinding disc to rotate around its own axis extending up and down;

[0012] Features:

[0013] The lower surface of the grinding disc is provided with a vertically arranged blade located at the outer periphery of the axis and extending in the radial direction of the grinding disc. The blade is arranged corresponding to the discharge port, and the blade can rotate with the grinding disc to disturb the fluid;

[0014] Also included are:

[0015] A one-way valve is arranged at or near the discharge port to close the discharge port, and the one-way valve is arranged to be movable to open the discharge port under the action of the fluid disturbed by the blades in the pulverizing chamber.

[0016] In the natural state, the one-way valve closes the discharge port. At this time, the water flow entering from the water inlet is accumulated in the grinding chamber (that is, the water inlet speed is greater than the water discharge speed). Then the driving mechanism works to drive the grinding disc and the blades to rotate. The rotating blades 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 a pressure to the one-way valve to make the one-way valve open the discharge port, so that the fluid is quickly discharged from the discharge port together with the cleaned residue. Therefore, the utility model is conducive to the discharge of kitchen waste after grinding.

[0017] Preferably, the grinding disc is located above the discharge port, and the lower edge of the blade is arranged corresponding to the upper part of the discharge port.

[0018] Further, the one-way valve includes a valve plate, at least the lower side of which is provided with a counterweight, and the upper side of which is rotatably constrained at the discharge port or a position adjacent to the discharge port, and the valve plate always has a tendency to rotate downward and horizontally block the discharge port under the gravity of the counterweight, and at the same time, the valve plate is arranged to overcome the gravity of the counterweight and rotate upward to open the discharge port under the action of the fluid disturbed by the blades in the crushing chamber. In addition, the one-way valve can also adopt the existing duckbill valve and other structures.

[0019] Furthermore, the edge of the discharge port extends outward relative to the side wall of the pulverizing chamber;

[0020] The valve plate is located outside the discharge port, and under the action of the gravity of the counterweight block, it always has a tendency to rotate downward so that the surface of the valve plate fits the edge of the discharge port, and when the surface of the valve plate fits the edge of the discharge port, the surface of the valve plate tilts outward from top to bottom.

[0021] The inclined valve plate is conducive to opening and closing the discharge port.

[0022] Preferably, there are at least two blades, which are circumferentially spaced and disposed at the periphery of the axis and relatively close to the edge of the grinding disc. The blades can also assist the grinding disc in crushing the kitchen waste.

[0023] Preferably, the radial extension length L1 of the blade is half of the radius of the grinding disc.

[0024] Preferably, the extension length of the blade relative to the lower surface of the grinding disc is denoted as L2, and the shortest distance between the lower surface of the grinding disc and the bottom wall of the pulverizing chamber is denoted as h, and both satisfy: L2 = 2 / 3 × h.

[0025] This is beneficial to the disturbance of the fluid by the blades and the discharge of the fluid.

[0026] Furthermore, the lower edge of the discharge port extends upward toward the center of the crushing chamber to form an inclined surface, the upper edge of the inclined surface is located at the bottom center of the crushing chamber, and the upper edge of the inclined surface further extends horizontally to form a plane, the plane and the inclined surface constitute the bottom wall of the crushing chamber, and the spacing distance between the lower surface of the grinding disc and the plane is h.

[0027] The design of the inclined surface and the design of the position and size of the blades in the utility model are conducive to the rapid discharge of the fluid in the crushing chamber, further improving the drainage effect.

[0028] Preferably, the angle between the inclined plane and the horizontal plane is denoted as a, 0°<a≤45°.

[0029] To further solve the above second technical problem, preferably, the grinding disc includes:

[0030] The first plate body has a side edge in the shape of teeth with concave and convex parts alternately arranged circumferentially;

[0031] The second disc body is horizontally placed above the first disc body and can rotate together with the first disc body under the action of the driving mechanism. A grinding hammer is arranged on the upper surface of the second disc body.

[0032] Preferably, the first disk body has a tongue piece with a flanged edge at its periphery, and the bent tongue piece extends upward relative to the upper surface of the first disk body, and a first strip hole and a second strip hole are formed by the flanged edge bending of the tongue piece, wherein:

[0033] The first strip hole extends from the side of the first disk body to the center, and the outer end of the first strip hole opens to the side of the first disk body;

[0034] 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;

[0035] The second disk body is provided with a through hole penetrating through the wall thickness thereof, so as to allow the tongue piece to pass through.

[0036] In this way, the tongue piece and the grinding hammer can crush the kitchen waste together to improve the crushing effect. In addition, the tongue piece of the utility model is integrally formed on the first disc body, and the structure is simple; the perforated design on the second disc body can prevent the root of the tongue piece from bending.

[0037] Compared with the prior art, the advantages of the utility model are: under the natural state, the one-way valve closes the discharge port. At this time, the water flow entering from the water inlet is accumulated in the crushing chamber (that is, the water inlet speed is greater than the water discharge speed). Then the driving mechanism works to drive the grinding disc and the blades to rotate. The rotating blades 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 one-way valve to make the one-way valve open the discharge port, so that the fluid is quickly discharged from the discharge port together with the cleaned residue. Therefore, the utility model is conducive to the discharge of kitchen waste after crushing. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0047] like Figures 1 to 8 As shown, a preferred embodiment of a food waste disposer of the present invention is shown, and the food waste disposer includes a crushing cover 1, a grinding assembly, a driving mechanism 200 and a one-way valve 86.

[0048] The crushing cover 1 has a crushing chamber 10 inside, and 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 on the side wall of the lower part of the crushing chamber 10. The feed port 10a is located at the top of the crushing chamber 10, and the water inlet 10c is located below the feed port 10a, and a solenoid valve is provided at the water inlet 10c. The edge of the discharge port 10b extends outward relative to the side wall of the crushing chamber 10. At the same time, in this embodiment, Figures 2 to 4 and Figure 8 As shown, the lower edge of the discharge port 10b extends upward toward the center of the crushing chamber 10 to form an inclined surface 11, and the angle a between the inclined surface 11 and the horizontal plane is ≤45° (the angle a can be any value between 0°<a≤45°, such as angle a is 5°, 10°, 20°, 30°, 45°, etc.), the upper edge of the inclined surface 11 is located at the bottom center of the crushing chamber 10, and the upper edge of the inclined surface 11 further extends horizontally to form a plane 12, and the plane 12 and the inclined surface 11 constitute the bottom wall of the crushing chamber 10.

[0049] The grinding assembly includes a grinding disc 20 and blades 23, wherein the grinding disc 20 is horizontally placed in the crushing chamber 10, and is located above the discharge port 10b and below the water inlet 10c, for crushing the garbage entering from the feed port 10a. The driving mechanism 200 is a motor, and its output end acts on the grinding disc 20, for driving the grinding disc 20 to rotate around its own axis extending up and down.

[0050] In this embodiment, Figures 5 to 7 As shown, the grinding disc 20 includes a first disc body 21 and a second disc body 22 arranged coaxially, the first disc body 21 has a tongue piece 210 with a flanged bend at its side, and the bent tongue piece 210 extends upward relative to the upper surface of the first disc body 21, and at the same time, 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 side of the first disc body 21 to the center, and the outer end of the first strip hole 211 opens to the side of the first disc body 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 bent tongue pieces 210, which are arranged on the first disc body 21 at equal intervals along the circumferential direction and extend along the radial direction of the first disc body 21. At the same time, the side of the first plate body 21 is in a tooth shape with concave and convex parts alternately arranged circumferentially, and tooth-shaped notches 213 are formed on the side of the first plate body 21 at positions corresponding to the tongue pieces 210 .

[0051] The second plate 22 is horizontally placed above the first plate 21 and can rotate together with the first plate 21 under the action of the driving mechanism 200. A grinding hammer 221 is provided on the upper surface of the second plate 22. A through hole 220 penetrating the wall thickness of the second plate 22 is provided at a position corresponding to each tongue piece 210, so that the corresponding tongue piece 210 can pass through.

[0052] The blade 23 is vertically arranged on the lower surface of the first disk body 21 adjacent to the side of the first disk body 21, and extends radially along the first disk body 21, and the radial extension length L1 is half of the radius of the grinding disk 20. And the lower edge of the blade 23 is arranged corresponding to the upper part of the discharge port 10b. Let the extension length of the blade 23 relative to the lower surface of the first disk body 21 be L2, and let the vertical distance between the lower surface of the first disk body 21 and the plane 12 of the bottom wall of the crushing chamber 10 be h, and both satisfy: L2 = 2 / 3 × h. And in this embodiment, there are two blades 23, and they are arranged at intervals along the circumferential direction on the periphery of the axis. Therefore, when the blade 23 rotates with the grinding disk, the blade 23 can disturb the rotation of the fluid in the crushing chamber.

[0053] like Figure 3 , 4 As shown, the one-way valve 86 includes a valve plate 861, which 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] The steps of the self-cleaning method of this embodiment are as follows:

[0055] 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 assembly;

[0056] Second, the driving mechanism 200 drives the grinding disc 20 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;

[0057] 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.

[0058] At the same time, during normal crushing operation, the cooperation between the blade 23 and the one-way valve 86 in this embodiment can also ensure that the crushed kitchen waste is discharged quickly and effectively.

[0059] In the specification and claims of the present invention, terms indicating directions, such as "upper", "lower", "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, "upper" and "lower" 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.
