Description

Technical Field

[0001] This invention generally relates to the field of kitchen appliances, and more particularly to food scraping devices and drainage systems. Background Technology

[0002] Common sink drain filters have a simple structure. During drainage, their filter holes are easily clogged by debris, reducing drainage efficiency. Furthermore, the sink strainer basket needs to be removed and emptied after each wash, and the small residues are already quite dirty after washing, creating an unpleasant user experience. Excessive residue can also clog the strainer basket, preventing water from draining. After a period of use, small debris, along with grease, accumulates in the drain pipe's bend. Over time, this buildup can clog the drain, rendering the sink unusable, causing unpleasant odors, and resulting in a poor repair experience.

[0003] Therefore, a device is proposed that can break up the residue in the water tank. After the residue in the water tank is broken up by the device, it can be directly flushed away without the need for manual cleaning. However, common residue breaking devices use a blade to break up the residue, which takes a long time and is inefficient. Summary of the Invention

[0021] As an implementation method, the transmission mechanism includes a third-stage transmission, which includes the fourth transmission gear and the second cutter group, with the fourth transmission gear meshing with the transmission gear.

[0022] As one possible implementation, the slag crushing device includes: an inlet, at which the cutter head assembly is installed;

[0023] The outlet is located on the side of the slag crushing device and is at the same height as the drainage impeller.

[0024] Secondly, a drainage system is provided, including the aforementioned slag-crushing device.

[0025] The drainage system further includes at least one drainage trough, the slag crushing device is installed below the drainage trough, and each of the drainage troughs is connected to the inlet of the slag crushing device through a first drain pipe.

[0057] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0058] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0059] Please refer to Figures 1 to 11 As shown, this embodiment provides a slag crushing device 100, including:

[0060] The cutter head assembly 120 includes a first cutter group 122 and a second cutter group 121 with opposite rotation directions, used for crushing residue;

[0061] The transmission mechanism 130 includes two transmission gears with opposite rotation directions, which are respectively connected to the first cutter group 122 and the second cutter group 121, for driving the first cutter group 122 and the second cutter group 121 to rotate in opposite directions.

[0062] The drive device 140 is used to drive the transmission mechanism 130 to rotate.

[0063] This embodiment provides a first blade group 122 and a second blade group 121 with different rotation directions to crush residual waste, so that the crushing device 100 has higher crushing efficiency and better crushing effect. At the same time, a drive device 140 is set to drive the first blade group 122 and the second blade group 121, and the transmission mechanism 130 realizes the transmission and bidirectional rotation control, which improves the relative speed of the blade assembly 120 and improves the processing effect of kitchen waste.

[0064] The shredder 100 is installed below the drainage trough and is connected to the inlet 161 of the shredder 100 through the first drain pipe of the drainage trough. The shredder 100 is provided with a water pipe structure that is connected to the first drain pipe. The water pipe structure outside the shredder 100 can also be used as part of the first drain pipe, so that the shredder 100 can be installed inside the first drain pipe.

[0065] Optionally, it includes: a first drive shaft 110, the cutter head assembly 120 is mounted on the first drive shaft 110, and the transmission mechanism 130 and the drive device 140 are both connected to the first drive shaft 110. The first drive shaft 110 is used to transmit the driving force of the drive device 140 to the transmission mechanism 130 and the cutter head assembly 120.

[0066] like Figure 4 and Figure 5 As shown, the shredding device 100 includes a first drive shaft 110, which is mounted on a first drain pipe or on a water pipe structure outside the shredding device 100 via bearings 111, ensuring that the first drive shaft 110 can rotate. A cutter head assembly 120 and a drainage impeller 150 for drainage are arranged around the first drive shaft 110. A friction bushing 181 is provided between the cutter head assembly 120 and the first drain pipe. The friction bushing 181 is interference-fitted with the first drain pipe, or it can be integrally injection molded with the first drain pipe as an insert, ensuring that the first drain pipe does not leak at the position of the friction bushing 181, i.e., the position where the cutter head assembly 120 is mounted on the first drain pipe. Simultaneously, a sealing ring 182 is provided between the friction bushing 181 and the cutter head assembly 120 to seal the gap between them, preventing leakage. Preferably, two sealing rings 182 are fitted onto the cutter head assembly 120, and corresponding transmission teeth are provided on the cutter head assembly 120 between the two sealing rings 182 to drive the rotation of the cutter head assembly 120. Preferably, the sealing rings 182 are made of wear-resistant rubber, which can meet the requirement of working for at least 1000 hours at a working state of 3000 rpm.

[0067] The shredding device 100 is also equipped with a drive device 140, which drives the transmission mechanism 130. The transmission mechanism 130 drives the first blade group 122 and the second blade group 121 on the cutter head assembly 120 to rotate in different directions. The drive device 140 is connected to the first transmission shaft 110. The drive device 140 drives the first transmission shaft 110 to rotate, which in turn drives part of the cutter head assembly 120, namely the first blade group 122, which is mounted on the first transmission shaft 110, to rotate. At the same time, the drive device 140 drives the transmission structure to rotate, and the transmission mechanism 130 drives the other part of the blade assembly, namely the second blade group 121, to rotate in the opposite direction to the first blade group 122.

[0068] Furthermore, it also includes a drainage impeller 150, which is mounted on the first drive shaft 110 and located at one end of the cutter head assembly 120 away from the inlet 161 of the slag crushing device 100. The drainage impeller 150 is driven to rotate by the drive device 140.

[0069] The shredding device 100 provided in this embodiment is also equipped with a drainage impeller 150. The drainage impeller 150 is installed on the first drive shaft 110 and is located below the cutter head assembly 120. When the cutter head assembly 120 shreds the garbage, the shreds are discharged into the sewer through the drainage impeller 150. The drainage impeller 150 is installed on the first drive shaft 110. When the drive device 140 drives the first drive shaft 110 to rotate, it also drives the drainage impeller 150 to rotate. That is, when the drive device 140 starts and the blade assembly starts to rotate, the drainage impeller 150 also rotates at the same time to discharge the shreds.

[0070] Optionally, the diameter of the drainage impeller 150 gradually increases from one end to the other, and the diameter of the end of the drainage impeller 150 near the cutter head assembly 120 is larger than the diameter of the end of the drainage impeller 150 away from the cutter head assembly 120.

[0071] like Figure 11 The diagram shows the structure of the drainage impeller 150 provided in this embodiment. The diameter of the drainage impeller 150 gradually increases from one end to the other, forming a conical structure that is smaller at the top and larger at the bottom. During installation, it is also installed in this top-to-bottom shape. This structure ensures that the drainage impeller 150 will not be jammed, while increasing the drainage passage area, making the discharge of wastewater and waste residue smoother and the operation of the drainage impeller 150 more efficient. The drainage impeller 150 has an annular body 151, which is fitted onto the first drive shaft 110 with an interference fit. The outer surface of the annular body 151 has multiple blades 152, which are narrower at the top and wider at the bottom. The number of blades 152 is set to an even number to maintain dynamic balance when the drainage impeller 150 rotates. Preferably, the number of blades 152 is 6 or more, ensuring stable operation of the drainage impeller 150.

[0072] A pressure ring 170 is provided between the drainage impeller 150 and the bearing. The pressure ring 170 is sleeved on the first drive shaft 110, with one end of the pressure ring 170 pressing against the drainage impeller 150 and the other end pressing against the bearing, thus restricting the position of the upper end of the drainage impeller 150. At the same time, an annular boss 112 is provided on the first drive shaft 110 at the lower end of the drainage impeller 150. The lower end of the drainage impeller 150 abuts against the annular boss 112, thereby restricting the position of the lower end of the drainage impeller 150, so that the drainage impeller 150 can only rotate with the first drive shaft 110 and will not move up and down along the first drive shaft 110.

[0073] Furthermore, the first blade assembly 122 includes a base 1221, which is fixedly mounted on the first drive shaft 110. The surface of the base 1221 is an arc-shaped surface, and the outer peripheral surface is provided with a plurality of grinding teeth 1222.

[0074] The cutter head assembly 120 provided in this embodiment includes two parts, wherein the first cutter group 122 is disposed in the middle and the second cutter group 121 is disposed around the first cutter group 122. The two rotate in different directions to achieve higher slag crushing efficiency.

[0075] Furthermore, the first blade assembly 122 also includes a processing blade 1223, which is fixedly mounted on the base 1221 and includes at least a first blade 1224 and a second blade 1225 with different directions. The first blade 1224 has an angle with the surface of the base 1221, and the second blade 1225 is fitted to the surface of the base 1221.

[0076] like Figure 4 and Figure 9 As shown, the first blade assembly 122 comprises two parts: a base 1221 in the lower part and a processing blade 1223 in the upper part. The base 1221 is mounted on the first drive shaft 110 via a limiting ring. The processing blade 1223 is mounted on the base 1221 and fixed between the first drive shaft 110 and the base 1221 by fastening screws. The rotation of the first drive shaft 110 causes the processing blade 1223 and the base 1221 to rotate simultaneously. Grinding teeth 1222 are provided around the bottom periphery of the base 1221. When the base 1221 rotates at high speed, the grinding teeth 1222 can mask the kitchen waste thrown to the surrounding area by the centrifugal force of rotation.

[0077] The processing blade 1223 mounted on the base 1221 includes blades of different heights. The first blade 1224 is positioned higher, used to shred kitchen waste upon contact or to strike the kitchen waste onto the annular second blade assembly 121. The second blade 1225 is positioned lower and close to the surface of the base 1221, used to cut and shred kitchen waste that falls onto the surface of the base 1221. Simultaneously, the surface of the base 1221 is designed as an arc-shaped surface, preferably a spherical surface, and the second blade 1225 is also designed as an arc-shaped structure, completely fitting the base 1221, so that there are no gaps between the second blade 1225 and the base 1221, thus eliminating any dead corners for waste to accumulate, allowing the waste to be completely shredded and flushed away. The first blade 1224 can also be configured as follows... Figure 9 The upward-sloping form shown can also be set to a horizontal form.

[0078] Furthermore, the second blade assembly 121 includes: an annular body 1211, the outer wall of which is provided with transmission teeth 1212, the transmission teeth 1212 being arranged around the annular body 1211.

[0079] The cutting teeth, a plurality of the cutting teeth are provided on the inner wall of the annular body 1211 and arranged at different heights on the inner wall of the annular body 1211.

[0080] like Figure 10 The diagram shows the structure of the second blade assembly 121, which is an annular structure surrounding the first blade assembly 122. The friction bushing 181 described in the previous embodiment is fitted onto the annular body 1211 of the second blade assembly 121, and the sealing ring 182 is also fitted onto the annular body 1211 to form a sealing structure. A transmission tooth 1212 is provided on the outer wall of the annular body 1211 of the second blade assembly 121. This transmission tooth 1212 surrounds the annular body 1211 and drives the rotation of the second blade assembly 121 through the cooperation of the transmission mechanism 130 and the transmission tooth 1212. The transmission tooth 1212 is located in the middle of the annular body 1211 and between the two sealing rings 182, giving the sealing rings 182 a better sealing effect and making the rotation drive of the second blade assembly 121 more stable. Multiple blades are provided on the inner wall of the annular body 1211 and arranged at different heights, allowing the blades to crush waste of different heights.

[0081] Optionally, the cutting teeth include: cutting teeth 1213, the cutting teeth 1213 having a strip-shaped cross-section and extending along the circumferential direction of the annular body 1211.

[0082] The tearing tooth 1214 is conical, and the cutting tooth 1213 is disposed above the tearing tooth 1214 and close to the inlet 161.

[0083] The blades on the inner wall of the annular body 1211 provided in this embodiment include two types: one is the upper cutting teeth 1213, which are strip-shaped and arranged along the circumference of the annular body, and are used to cut fibrous kitchen waste when the second blade assembly 121 rotates; the other is the lower tearing teeth 1214, which are conical structures and are relatively sharp, and are used to tear brittle or large pieces of kitchen waste when the second blade assembly 121 rotates.

[0084] In this embodiment, the distance between the base 1221 and the annular body 1211 needs to be set to an appropriate distance. It should not be set too large, which would affect the degree of cutting and crushing of the waste by the grinding teeth 1222 and the cutting teeth 1213. It should not be set too small, which would make the area for accommodating the waste too small, or affect the grinding effect of the teeth.

[0085] When the aforementioned blade assembly 120 is in use, the kitchen waste first touches the first blade 1224 as it falls downwards. The first blade 1224 cuts or strikes the kitchen waste it touches onto the annular body 1211. The waste is then further cut and torn by the teeth on the annular body 1211 of the second blade assembly 121. Under the action of gravity, the waste falls onto the base 1221, where it is cut and crushed by the second blade 1225 that is attached to the base 1221. At the same time, under the action of centrifugal force, the waste is thrown between the annular body 1211 of the second blade assembly 121 and the base 1221. The grinding teeth 1222 arranged circumferentially on the base 1221 grind and crush the waste. The debris falls from the gap between the annular body 1211 and the base 1221 and enters the position of the drain impeller 150. Under the action of the drain impeller 150, the waste is discharged from the second drain pipe.

[0086] Furthermore, the transmission mechanism 130 includes: a first-stage transmission, the first-stage transmission including a first transmission gear 131, the first transmission gear 131 being mounted on the output shaft of the drive device 140;

[0087] The second transmission gear 132 meshes with the first transmission gear 131.

[0088] refer to Figure 6 , Figure 7 As shown, in this embodiment, a drive mechanism is provided to drive the transmission mechanism 130 and the first transmission shaft 110. The transmission mechanism 130 needs to control the rotation of the first tool group 122 and the second tool group 121 in different directions. Therefore, the transmission mechanism 130 is set to an odd number of transmission stages. For example, if the transmission stage of the transmission mechanism 130 is N, then the first stage structure is connected to the first tool group 122, and the Nth stage is connected to the second tool group 121. When the drive mechanism is driving, it realizes the opposite rotation of the first tool group 122 and the second tool group 121. In this embodiment, a three-stage transmission is preferably adopted.

[0089] like Figure 2 As shown, the transmission mechanism 130 is protected by a protective cover 137. To clarify the specific structure of the transmission mechanism 130, Figure 6 The Lieutenant General's protective shield 137 is removed for display. Figure 7The drive unit 140 is removed for display. The transmission mechanism 130 includes a first transmission gear 131, which is connected to the output shaft of the drive unit 140 and coaxially arranged with the first transmission shaft 110, providing the first stage of power input for the entire transmission mechanism 130. Since both the first transmission gear 131 and the first transmission shaft 110 are connected to the output shaft of the drive unit 140, the rotation directions of the first transmission gear 131 and the first transmission shaft 110 are the same. The rotation direction of the first tool assembly 122 mounted on the first transmission shaft 110 is the same as the rotation direction of the first transmission gear 131.

[0090] A second transmission gear 132 is provided, which meshes with the first transmission gear 131. The rotation direction of the second transmission gear 132 is opposite to the rotation direction of the first transmission gear 131 and the first cutter assembly 122. The first-stage power is transmitted through the second transmission gear 132. The second transmission gear 132 is mounted on a third transmission shaft 136, which is fixed to the first drain pipe or to a pipe outside the slag crushing device 100 by a friction ring. At the same time, the second transmission gear 132 is fixed to the third transmission shaft 136 by gear fixing screws.

[0091] Furthermore, the transmission mechanism 130 includes a second-stage transmission, which includes a second transmission shaft 135 fixed to the side of the first transmission shaft 110.

[0092] The third transmission gear 133 and the fourth transmission gear 134 are respectively mounted at both ends of the second transmission shaft 135, and the third transmission gear 133 meshes with the second transmission gear 132.

[0093] In this embodiment, a second drive shaft 135 is provided, and a third drive gear 133 and a fourth drive gear 134 are respectively installed at both ends of the second drive shaft 135. These gears are fixed to both ends of the second drive shaft 135 with gear fixing screws. Therefore, the rotation direction and rotation speed of the third drive gear 133 and the fourth drive gear 134 are the same. The third drive gear 133 meshes with the second drive gear 132, transmitting the power of the second drive gear 132 to the fourth drive gear 134 through the third drive gear 133. The second drive gear 132 serves as an intermediate transmission mechanism. (Refer to...) Figure 8The diagram on the left illustrates the rotational directions between the first transmission gear 131, the second transmission gear 132, and the third transmission gear 133. Therefore, the rotational directions of the third transmission gear 133 and the fourth transmission gear 134 are opposite to those of the second transmission gear 132, but the same as those of the first transmission gear 131 and the first cutter group 122, thus achieving the second stage of power transmission. In this embodiment, the second transmission shaft 135 is preferably fixed to the first drain pipe or the external pipe of the slag crushing device 100 via a friction ring.

[0094] Furthermore, the transmission mechanism 130 includes a third-stage transmission, which includes the fourth transmission gear 134 and the second cutter group 121, with the fourth transmission gear 134 meshing with the transmission gear 1212.

[0095] refer to Figure 7 As shown, the fourth transmission gear 134, positioned above the second transmission shaft 135, meshes with the transmission gear 1212 on the second tool assembly 121 to form a gear pair. This gear 134 drives the second tool assembly 121 to rotate. The rotation direction of the fourth transmission gear 134 is opposite to that of the second tool assembly 121. (Refer to...) Figure 8 The diagram on the right shows the rotation direction of the fourth transmission gear 134 and the second cutter group 121; therefore, the rotation direction of the second cutter group 121 is opposite to the rotation direction of the first cutter group 122, realizing the rotation of the two cutter groups in different directions.

[0096] Specifically, according to Figure 8 For example, when the drive device 140 rotates clockwise, both the first blade assembly 122 and the first transmission gear 131 rotate clockwise. The second transmission gear 132 meshes with the first transmission gear 131, therefore, the second transmission gear 132 rotates counterclockwise. The third transmission gear 133 meshes with the second transmission gear 132, therefore, the third transmission gear 133 rotates clockwise. The fourth transmission gear 134 is connected to the third transmission gear 133 on the same second connecting shaft, therefore, the fourth transmission gear 134 also rotates clockwise. Simultaneously, the transmission teeth 1212 on the second blade assembly 121 mesh with the fourth transmission gear 134, therefore, the second blade assembly 121 rotates counterclockwise. The entire transmission mechanism 130 achieves the directional movement of the first blade assembly 122 and the second blade assembly 121, increasing their relative speed and thus improving the processing effect. In this embodiment, the transmission mechanism 130 can also be configured with five or more transmission stages to achieve the reverse movement of the first blade assembly 122 and the second blade assembly 121, ensuring that it is an odd-numbered transmission stage.

[0097] Furthermore, the slag crushing device 100 includes an inlet 161, and the cutter head assembly 120 is installed at the inlet 161;

[0098] The outlet 162 is located on the side of the slag crushing device 100 and is at the same height as the drainage impeller 150.

[0099] The slag crushing device 100 provided in this embodiment is provided with an inlet 161 and an outlet 162. Wastewater and slag are discharged into the sewer through the outlet 162. Preferably, the outlet 162 is located next to the drainage impeller 150. When the drainage impeller 150 rotates, it directly discharges the wastewater and slag. At the same time, a second drain pipe is installed at the outlet 162. The second drain pipe has a bend, so that after the wastewater is discharged, there is a certain amount of water residue in the bend, so as to block the odor in the sewer.

[0100] The shredder 100 provided in this embodiment can not only improve the shredding efficiency and effect of kitchen waste, but also promptly remove the shredded waste, so that the granular waste will not accumulate at the second drain pipe and will not cause the problem of easy blockage at the bend of the drain pipe.

[0101] This embodiment also provides a drainage system, including the aforementioned slag crushing device 100.

[0102] The drainage system further includes at least one drainage trough 400, the slag crushing device 100 is installed below the drainage trough 400, and each of the drainage troughs 400 is connected to the inlet 161 of the slag crushing device 100 through a first drain pipe 200.

[0103] The drainage system mentioned in this embodiment is generally a water tank drainage structure. A first drain pipe 200 is installed under the water tank to discharge the sewage in the water tank. By installing the shredder 100 in the above embodiment under the water tank, the garbage in the water tank is directly shredded and then flushed away through the sewer, eliminating the need for manual cleaning of the water tank garbage. At the same time, the shredder 100 in this embodiment can shred the garbage through two sets of blades with different rotation directions, resulting in higher shredding efficiency and better shredding effect. Generally, a double-tank structure is used in water tank drainage structures, with the shredder 100 placed under either drainage trough 400, forming a structure like... Figure 1 and Figure 2 The structure shown is preferably positioned below the larger drainage trough 400, that is, below the main drainage trough 400. The smaller drainage trough 400 is connected to the inlet 161 of the shredding device 100 via a drain pipe, so that the waste in both drainage troughs 400 can be processed by the shredding device 100. Alternatively, the drainage system can adopt a large single-trough design, providing only one drainage trough 400, with the shredding device 100 positioned below this drainage trough 400 to crush the waste, forming a structure like... Figure 3 The structure shown.

[0104] Furthermore, each of the first drain pipes 200 below the drainage trough 400 is provided with a water inlet, and the water inlet is equipped with a water inlet valve 300. The opening time of the water inlet valve 300 is greater than or equal to the opening time of the slag crushing device 100.

[0105] In the above embodiment, the shredder 100 is installed below the drainage trough 400 to shred the garbage in the drainage trough 400. The shredded garbage also needs to be flushed away directly. The outlet 162 of the shredder 100 is connected to the first drain pipe 200 for the discharge of sewage and waste. Therefore, a water inlet is also required. When the shredder 100 is shredding, water enters through the water inlet to flush the shredded garbage to the outlet 162 and discharge it into the sewer through the second drain pipe 600. The shredder 100 shreds and flushes simultaneously, so that the garbage entering the second drain pipe 600 is a mixture of solid and liquid, which facilitates the treatment and discharge of kitchen waste. In this embodiment, an inlet valve 300 is also installed at the inlet to control whether water enters the inlet. Generally, when the shredder 100 starts working, the inlet valve 300 is opened to flush the shredder. After the shredder 100 stops working, the inlet valve 300 remains open for a period of time to further flush the shredder 100 for the purpose of rinsing and deodorizing. This ensures that the water remaining in the second drain pipe 600 at the outlet 162 is clean and can remain clean even after long periods of non-use, without developing an odor.

[0106] Furthermore, it also includes a controller 500, which is electrically connected to the inlet valve 300 and the drive device 140, and is used to control the start and stop of the inlet valve 300 and the drive device 140.

[0107] A control switch 510 is disposed on the side of the drainage trough 400 and electrically connected to the controller 500, and is used to control the start and stop of the controller 500.

[0108] In this embodiment, the drainage system is equipped with a controller 500, which controls the start and stop of the inlet valve 300 and the drive device 140. Optionally, when the controller 500 controls the drive device 140 to start and the shredding device 100 starts shredding, the inlet valve 300 is started simultaneously to flush the system. The running time of the drive device 140 is set to X, and the running time of the inlet valve 300 is set to Y. Y is set to ≥ X, so that the inlet valve 300 stops after the drive device 140 stops, allowing for a longer flushing time. After the set time Y is reached, the controller 500 controls the inlet valve 300 to close, and the entire machine stops operating. The water that is not discharged accumulates at the bottom of the second drain pipe 600, filling the gaps in the pipe and preventing odors from the drain pipes installed in the building from flowing into the tank through the drain pipe, thus playing a role in preventing odors.

[0109] Additionally, a control switch 510 is provided. This control switch 510 serves as a switch structure for driving and stopping the controller 500. It is located in a position easily accessible to the user, and can optionally be installed on the side of the drainage trough 400. Figure 1 and Figure 3 The positions shown are convenient for user operation. The control switch 510 is electrically connected to the controller 500 via a connecting cable. The drive device 140 and the water inlet valve 300 are also electrically connected to the controller 500 via connecting cables.

[0110] When using the drainage system provided in this embodiment, the user turns on the control switch 510, which controls the controller 500 to start. Under the action of the controller 500, the drive device 140 starts to rotate, driving the first blade group 122 and the second blade group 121 to rotate in different directions to crush the garbage. At the same time, it drives the drainage impeller 150 to rotate. At this time, the controller 500 controls the water inlet valve 300 to open, providing an external water source for the drainage system. Water enters through the water inlet valve 300 and first flushes the garbage under the smaller drainage tank 400 into the crushing device 100 for crushing. At the same time, the crushed garbage is flushed into the drain pipe and discharged into the sewer.
