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, after processing food waste, some small residues will remain inside the food waste disposers on the market. If the food waste disposer is not started for a long time or is used multiple times, the residues will 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, and their cleaning effect needs to be further improved. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a kitchen waste disposer capable of improving the self-cleaning effect in view of the current status of the prior art.

[0007] The technical solution adopted by the utility model to solve the above technical problems is: a kitchen waste disposer, comprising:

[0008] 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;

[0009] A crushing element is arranged in the crushing chamber and is used to crush the garbage entering from the feed inlet;

[0010] A driving mechanism, the output end of which acts on the crushing member to drive the crushing member to rotate;

[0011] It is characterized by also including:

[0012] A valve plate is provided with a counterweight block, and the valve plate is rotatably constrained at the discharge port or a position adjacent to the discharge port. Under the action of the gravity of the counterweight block, the valve plate always has a tendency to rotate to horizontally block the discharge port. At the same time, the valve plate is arranged to overcome the gravity of the counterweight block and rotate to open the discharge port under the action of the fluid disturbed by the crushing parts in the crushing chamber.

[0013] By setting a valve plate at the discharge port of the grinding chamber or at a position adjacent to the discharge port, in a natural state, the valve plate rotates under the gravity of the counterweight block to horizontally block the discharge port. At this time, the water flow entering from the water inlet accumulates in the grinding chamber (that is, the water inlet speed is greater than the water discharge speed), and then the driving mechanism works to drive the grinding parts to rotate. The rotating grinding parts 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 to enable the valve plate to overcome the gravity of the counterweight block and rotate to open the discharge port, so that the fluid is discharged from the discharge port together with the cleaned residue.

[0014] Therefore, the utility model can realize the self-cleaning of the food waste disposer by controlling the operation of the driving mechanism and the water inlet, and the structure is relatively simple.

[0015] Preferably, the upper side portion of the valve plate can be rotatably constrained at the discharge port or a position adjacent to the discharge port, and at least the lower side portion of the valve plate is provided with the above-mentioned counterweight block. Under the action of the gravity of the counterweight block, the valve plate always has a tendency to rotate downward and horizontally block the discharge port, and under the action of the fluid disturbed by the crushing parts in the crushing chamber, it can overcome the gravity of the counterweight block and rotate upward to open the discharge port.

[0016] Preferably, the edge of the discharge port extends outward relative to the side wall of the pulverizing chamber;

[0017] The valve plate is located outside the discharge port, and under 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. The inclined valve plate is conducive to opening and closing the discharge port.

[0018] Preferably, when the valve plate surface is in contact with the edge of the discharge port, the angle θ between the valve plate surface and the vertical plane is less than 90°. Further preferably, the angle θ is less than or equal to 60°.

[0019] Furthermore, when the driving mechanism stops working, the valve plate is arranged to be able to overcome the gravity of the counterweight block and rotate upward to open the discharge port under the action of the water stored in the crushing chamber, wherein the water storage liquid level is located above the crushing element. That is, when there is a lot of water stored in the crushing chamber, the water can be discharged by opening the discharge port. At this time, the height of the water stored in the crushing chamber can be controlled by controlling the water inlet speed. For example, when the water inlet speed is equal to the water discharge speed, the water storage height remains unchanged; when the water inlet speed is greater than the water discharge speed, the water storage height increases slowly; when the water inlet speed is less than the water discharge speed, the water storage height gradually decreases.

[0020] Preferably, the weight of the counterweight is t, the volume of the crushing chamber is v, the diameter of the crushing chamber is D, and the diameter of the discharge port is d, satisfying:

[0021] v=(t×cosθ / (ρ×g×π×d 2 )-d / 8)×π×D 2

[0022] Among them, ρ is the density of water and g is the acceleration due to gravity, 9.8N / kg.

[0023] That is, the required water storage capacity can be achieved by adjusting the weight of the counterweight. The water storage capacity is generally v / 2.

[0024] In the above schemes, preferably, the crushing piece is in the shape of a disk as a whole, which is horizontally placed in the crushing chamber, below the feed port and above the discharge port, and can rotate around its own axis extending up and down under the drive of the driving mechanism.

[0025] Preferably, the lower surface of the disc-shaped body is provided with blades, at least part of the blades extends downward, and the downwardly extending part is recorded as a vertical part, and at least the lower part of the vertical part is arranged corresponding to the discharge port. The arrangement of the blades is conducive to disturbing the fluid, and the blades pressurize the fluid by high-speed stirring to achieve rapid discharge of the fluid. During the discharge process, the valve plate can be strongly flushed to ensure the reliable operation of the valve plate.

[0026] Preferably, there are at least two blades, which are circumferentially spaced apart and disposed at the periphery of the axis and relatively close to the edge of the disc-shaped body.

[0027] Preferably, the vertical portion extends in a radial direction of the disc-shaped body, and a radial extension length L1 is half of a radius of the disc-shaped body.

[0028] Preferably, the extension length of the vertical portion relative to the lower surface of the disc-shaped body is denoted as L2, and the shortest distance between the lower surface of the disc-shaped body and the bottom wall of the pulverizing chamber is denoted as h, and both satisfy: L2=2 / 3×h.

[0029] In the above schemes, preferably, the feed port is located at the top of the pulverizing chamber, the water inlet is arranged below the feed port, and a solenoid valve is provided at the water inlet.

[0030] The cleaning method of the kitchen waste disposer of the utility model comprises the following steps:

[0031] 1. The driving mechanism stops working, and water is introduced into the water inlet, so that water is stored in the crushing chamber, and the water level is above the crushing element;

[0032] Second, the driving mechanism drives the crushing parts to rotate, so as to disturb the fluid to rotate and flush the inner wall of the crushing chamber. At the same time, the fluid opens the valve plate and discharges the flushed residue from the discharge port;

[0033] 3. When the driving mechanism runs for t1, water stops flowing into the water inlet, and the driving mechanism continues to drive the crushing parts to rotate for t2 and then stops working, wherein t1≤60s, t2≤30s.

[0034] Compared with the prior art, the utility model has the following advantages: by arranging a valve plate at the discharge port of the grinding chamber or at a position adjacent to the discharge port, in a natural state, the valve plate rotates downward under the action of the gravity of the counterweight block and blocks the discharge port horizontally. At this time, the water flow entering from the water inlet accumulates in the grinding chamber (that is, the water inlet speed is greater than or equal to the water discharge speed), and then the driving mechanism works to drive the grinding parts to rotate. The rotating grinding parts 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, so that the valve plate overcomes the gravity of the counterweight block and rotates upward to open the discharge port, so that the fluid is discharged from the discharge port together with the cleaned residue.

[0035] Therefore, the utility model can realize the self-cleaning of the food waste disposer by controlling the operation of the driving mechanism and the water inlet, and the structure is relatively simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0050] Embodiment 1:

[0051] like Figures 1 to 7 As shown, a preferred embodiment 1 of a food waste disposer of the present invention is shown. The food waste disposer includes a crushing cover 1, a crushing element 2, a driving mechanism 200 and a valve plate 861.

[0052] 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.

[0053] The crushing element 2 is disposed in the crushing chamber 10 and is used to crush the garbage entering from the feed port 10a. The output end of the driving mechanism 200 acts on the crushing element 2 and is used to drive the crushing element 2 to rotate.

[0054] In this embodiment, the crushing element 2 is in the shape of a disk, and is disposed horizontally in the crushing chamber 10 , below the water inlet 10 c and above the discharge port 10 b . The crushing element 2 includes a first grinding disc 21 and a second grinding disc 22 .

[0055] 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 along the radial direction of 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.

[0056] The first grinding disc 21 also has blades 23 with flanges and bends at its periphery (that is, the blades 23 and the first grinding disc 21 are an integral piece, and the flanges and bends of the blades 23 are formed in the same manner as the tongue 210, which will not be elaborated here), and the bent blades 23 extend downward relative to the lower surface of the first grinding disc 21 and are recorded as vertical portions 232, and the vertical portions 232 extend radially along the first grinding disc 21, and the radial extension length L1 is half the radius of the disc. The extension length of the bent blades 23 relative to the lower surface of the first grinding disc 21 is recorded as L2, and the shortest distance between the lower surface of the first grinding disc 21 and the bottom wall of the crushing chamber 10 is recorded as h, and both satisfy: L2 = 2 / 3 × h. In addition, the lower edge of the blade 23 is arranged corresponding to the upper portion of the discharge port 10b. For details, please refer to Figure 4 .

[0057] In this embodiment, there are two tongues 210 , which are arranged at equal intervals along the circumferential direction on the first grinding disc 21 . There are also two blades 23 , which are arranged at equal intervals along the circumferential direction on the first grinding disc 21 and are arranged alternately with the tongues 210 .

[0058] 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 positions corresponding to the tongue pieces 210 and the blades 23 .

[0059] 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.

[0060] 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.

[0061] 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 crushing element 2 in the crushing chamber 10.

[0062] The weight of the counterweight 862 is t, the volume of the crushing chamber 10 is v, the diameter of the crushing chamber 10 is D, and the diameter of the discharge port 10b is d, satisfying: v = (t × cosθ / ρ × g × π × d 2 -d / 8)×π×D 2 , where ρ is the density of water and g is the gravitational acceleration of 9.8 N / kg. At this time, when the driving mechanism 200 stops working, the valve plate 861 can overcome the gravity of the counterweight block 862 under the action of the water stored in the crushing chamber 10 and rotate upward to open the discharge port 10b, wherein the water storage level is located above the crushing element 2, and the water storage capacity is v / 2.

[0063] When the water storage capacity reaches the set value (v / 2), the valve plate 861 will reach a specific opening and closing angle, at which time the water inlet speed of the water inlet 10c is equal to the water discharge speed of the discharge port 10b, the water storage capacity remains constant, and the water storage is completed; at this time, the motor is turned on to drive the crushing element 2 to rotate at a high speed, thereby forming a vortex, which strongly flushes the inner wall surface of the crushing chamber 10 to achieve the cleaning of the crushing chamber 10. And by adjusting the weight of the counterweight block 862, the required water storage capacity can be adjusted.

[0064] The steps of the self-cleaning method of this embodiment are as follows:

[0065] 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;

[0066] Second, the driving mechanism 200 drives the crushing element 2 to rotate, so as to disturb the fluid to rotate and flush the inner wall surface of the crushing chamber 10. At the same time, the fluid opens the valve plate 861, and the flushed residue is discharged from the discharge port 10b;

[0067] 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.

[0068] When the food waste disposer has been used N times or more (N is a manually defined number of times), the self-cleaning program will be triggered; if the food waste disposer has not been used for a long time, such as more than 3 days, the self-cleaning program will be triggered.

[0069] Embodiment 2:

[0070] like Figures 8 to 10 As shown, it is a preferred embodiment 2 of a kitchen waste disposer of the utility model. This embodiment is basically the same as the embodiment 1, except that each blade 23 in this embodiment is an independent component, and is arranged on the lower surface of the first grinding disc 21 corresponding to the position of each tongue piece 210, and is connected to the first grinding disc 21 by screws. Each blade 23 has a horizontally extending tooth portion 231, and each tooth portion 231 is located in the corresponding notch 213. At the same time, each blade 23 also has the above-mentioned vertical portion 232 extending downward relative to the tooth portion 231, and the vertical portion 232 is located at the inner periphery of the periphery of the first grinding disc 21 and extends along the radial direction of the first grinding disc 21.

[0071] Embodiment three:

[0072] like Fig.11 As shown, it is a preferred embodiment 3 of a kitchen waste disposer of the utility model.

In a natural state, under the gravity of the counterweight 862, the surface of the valve plate 861 fits the edge of the discharge port 10b. At this time, 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°; under the action of the fluid disturbed by the crushing element 2 in the crushing chamber 10, the valve plate 861 overcomes the gravity of the counterweight 862 and rotates outward to open the discharge port 10b. In this embodiment, the angle of the valve plate 861 rotating outward is not greater than θ. In order to further increase the angle of the valve plate 861 rotating outward, an elastic member can be added, which makes the valve plate 861 always have a tendency to rotate inward. Under the action of the fluid disturbed by the pulverizing element 2 in the pulverizing chamber 10, the valve plate 861 overcomes the gravity of the counterweight block 862 and the elastic force of the elastic element to rotate outward to open the discharge port 10b.

[0073] Embodiment 4:

[0074] like Fig.12 , 13As shown, it is a preferred embodiment 4 of a kitchen waste disposer of the utility model, which is basically the same as the embodiment 1, except that in this embodiment, the direction of the discharge port 10b is rightward, the rear side portion 8612 (or the front side portion) of the valve plate is rotatably constrained to the discharge port 10b, and at least the front side portion (or the rear side portion) of the valve plate 861 is provided with a counterweight 862. In a natural state, under the gravity of the counterweight 862, the surface of the valve plate 861 fits the edge of the discharge port 10b, and at this time, the surface of the valve plate 861 tilts outward from top to bottom; under the action of the fluid disturbed by the crushing element 2 in the crushing chamber 10, the valve plate 861 overcomes the gravity of the counterweight 862 and rotates outward to open the discharge port 10b.

[0075] 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.

[0076] 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.

[0077] 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.
