A garbage disposal

Abstract

This invention discloses a garbage disposal unit, including a grinding chamber and a drainage trough located below the grinding chamber and communicating vertically with it. The height of the inner bottom wall of the drainage trough gradually decreases clockwise or counterclockwise along the circumference. The height of the inner bottom wall of the drainage trough gradually decreases radially from the middle portion to the outer perimeter. By setting the inner bottom wall of the drainage trough to gradually decrease clockwise or counterclockwise along the circumference, when the grinding assembly of the drainage trough rotates, the potential energy brought by the height difference of the inner bottom wall of the drainage trough is converted into the kinetic energy of the water flow, thereby increasing the impact force of the water flow in the drainage trough, increasing the sewage discharge pressure, effectively reducing the amount of food waste residue, increasing the sewage discharge pressure, accelerating the discharge speed of food waste, and preventing food waste residue and sewage from remaining in the drainage trough.

Description

Technical Field

[0001] This invention belongs to the field of waste disposal, and more specifically, relates to a waste disposer. Background Technology

[0002] With the improvement of living standards and the increasing variety of food, the amount of kitchen waste generated is also gradually increasing. Garbage disposers, as kitchen appliances that can process kitchen waste, are becoming increasingly popular. When a garbage disposer is working, food waste and water enter the water tank together. After being ground into small pieces by the collision and friction of the grinding components such as the blades, grinding hammers, and toothed rings, the food waste is ground into small pieces. These small pieces, along with water, then enter the drain tank and are discharged into the sewer pipe through the drain outlet on the drain tank. However, existing garbage disposers have a flat bottom drain tank with a slight slope at the connection to the drain outlet. This results in a slow discharge rate of food waste residue and wastewater, and food waste residue tends to remain in the drain tank after processing.

[0003] In view of this, the present invention is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a garbage disposal unit.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is to provide a garbage disposer, including a grinding chamber and a drainage trough located below the grinding chamber and communicating with the grinding chamber vertically, wherein the height of the inner bottom wall of the drainage trough gradually decreases clockwise or counterclockwise along the circumferential direction.

[0006] By setting the inner bottom wall of the garbage disposal's drain tank to gradually decrease clockwise or counterclockwise along the circumference, when the grinding components of the drain tank rotate, the potential energy brought by the height difference of the inner bottom wall of the drain tank is converted into the kinetic energy of the water flow, thereby increasing the impact force of the water flow in the drain tank, increasing the sewage discharge pressure, effectively reducing the amount of food waste residue and increasing the sewage discharge pressure, accelerating the discharge speed of food waste, and preventing food waste residue and sewage from remaining in the drain tank.

[0007] Furthermore, the height of the inner bottom wall of the drainage ditch gradually decreases radially from the middle portion to the outer perimeter. While the inner bottom wall of the drainage ditch decreases clockwise or counterclockwise along the circumference, it also decreases radially outward from the center. This structure facilitates the discharge of food residue with the water flow during wastewater disposal.

[0008] Furthermore, the angle between the height of the inner bottom wall of the drainage trough and the horizontal plane along the radial direction is α, where 0 < α ≤ 30°.

[0009] Furthermore, the height difference of the bottom wall inside the drainage trough gradually decreasing along the circumference is 2-25mm.

[0010] Furthermore, the outer peripheral edge of the inner bottom wall of the drainage trough is smoothly connected to the side wall of the drainage trough.

[0011] By making the outer periphery of the inner bottom wall of the drainage trough and the side wall of the drainage trough a smooth transition connection, dead angles are avoided at the connection between the outer periphery of the inner bottom wall of the drainage trough and the side wall of the drainage trough, and food residue can be prevented from accumulating at the connection between the inner bottom wall of the drainage trough and the side wall of the drainage trough and being unable to be discharged.

[0012] Furthermore, the waste disposer also includes a drain outlet, which is located on the side wall of the drainage trough and is connected to the bottom wall inside the drainage trough. The drainage trough gradually decreases in a clockwise or counterclockwise direction from one side of the drain outlet.

[0013] Furthermore, a water-retaining wall is provided on one side of the bottom wall of the drainage trough corresponding to the sewage outlet. The water-retaining wall is formed by the height difference between the highest and lowest points of the bottom wall as it gradually decreases along the circumference.

[0014] The water-blocking wall can block the flow of water in the circumferential direction, increasing the flushing force of the water on food residue. At the same time, the water-blocking wall is set on the side of the bottom wall inside the drainage channel corresponding to the sewage outlet, which can block food residue and guide food residue into the sewage outlet, making it convenient to discharge food waste residue.

[0015] Furthermore, the grinding chamber is provided with a grinding assembly, which is located above the drainage groove, and the height of the inner bottom wall of the drainage groove gradually decreases along the rotation direction of the grinding assembly;

[0016] Preferably, the inner bottom wall of the drainage groove gradually decreases in height along the rotation direction of the grinding assembly, with the center of the bottom wall as the center. Further, the grinding assembly includes a cutter disc having a radially arranged impeller extending towards the drainage groove.

[0017] Furthermore, the impeller of the grinding assembly is formed by radially arranged ribs or water-repellent blades.

[0018] Because the blade disc has an impeller arranged radially, this structure not only facilitates the discharge of food residue during drainage, but also facilitates the use of water flow to flush away any food residue that may remain in the drainage tank when the grinding assembly rotates and grinds.

[0019] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0020] (1) By setting the inner bottom wall of the garbage disposal drain to gradually decrease clockwise or counterclockwise along the circumference, when the grinding component of the drain rotates, the potential energy brought by the height difference of the inner bottom wall of the drain is converted into the kinetic energy of the water flow, thereby increasing the impact force of the water flow in the drain, increasing the sewage pressure, effectively reducing the amount of food waste residue and increasing the sewage pressure, accelerating the discharge speed of food waste, and preventing food waste residue and sewage from remaining in the drain.

[0021] (2) By making the outer periphery of the inner bottom wall of the drainage trough and the side wall of the drainage trough a smooth transition connection, the dead angle formed at the connection between the outer periphery of the inner bottom wall of the drainage trough and the side wall of the drainage trough can be avoided, thus preventing food residue from accumulating at the connection between the inner bottom wall of the drainage trough and the side wall of the drainage trough and being unable to be discharged.

[0022] (3) The water-blocking wall can block the flow of water in the circumferential direction, increase the flushing force of water on food residue, and the water-blocking wall is set on the side of the bottom wall inside the drainage channel corresponding to the sewage outlet, which can block food residue and guide food residue into the sewage outlet, making it convenient to discharge food waste residue.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0032] like Figures 1 to 2 As shown, the garbage disposal unit of the present invention includes a grinding chamber and a drainage trough 3 located below the grinding chamber and communicating vertically with it. The height of the inner bottom wall 31 of the drainage trough 3 gradually decreases clockwise or counterclockwise along the circumference. The inner bottom wall 31 of the drainage trough 3 has a conical structure with a higher center and lower periphery. The direction in which the inner bottom wall 31 of the drainage trough gradually decreases is related to the rotation direction of the grinding assembly. Preferably, the direction in which the inner bottom wall 31 of the drainage trough gradually decreases is the same as the rotation direction of the grinding assembly.

[0033] When the garbage disposal unit is working, food waste and water enter the garbage disposal unit's water storage tank 1. The water storage tank 1 contains a grinding component 2, including a blade disc 31, a toothed ring 32, and a grinding hammer 33. The motor 4 drives the blade disc 31 to rotate, causing the food waste to collide and rub against the blades 31, grinding hammer 33, and toothed ring 32, grinding the food waste into small pieces. Then, the small pieces and water enter the drainage tank 3 together, and then enter the sewer pipe through the drain outlet 33 of the drainage tank 3.

[0034] Existing garbage disposals have a flat bottom and a small ramp at the drain outlet. This structure relies entirely on the gravity of the water and the centrifugal force of the rotating disc to drain water and food scraps, without adding any pressure. This results in food scraps remaining inside the garbage disposal and slow garbage scrap discharge.

[0035] This invention sets the inner bottom wall 31 of the garbage disposal drain 3 to gradually decrease clockwise or counterclockwise along the circumference. When the grinding component of the drain 3 rotates, the potential energy brought by the height difference of the inner bottom wall 31 of the drain 3 is converted into the kinetic energy of the water flow, thereby increasing the impact force of the water flow in the drain 3, increasing the sewage discharge pressure, effectively reducing the amount of food waste residue and increasing the sewage discharge pressure, accelerating the discharge speed of food waste, and preventing food waste residue and sewage from remaining in the drain 3.

[0036] Furthermore, the height of the inner bottom wall 31 of the drainage trough gradually decreases from the middle portion to the outer peripheral edge in the radial direction. While the inner bottom wall 31 of the drainage trough gradually decreases in the circumferential direction clockwise or counterclockwise, it also gradually decreases radially outward from the center. This structure is more conducive to the discharge of food residue with the water flow during sewage discharge.

[0037] The height of the inner bottom wall 31 of the drainage trough forms an angle α with the horizontal plane along the radial direction, where 0 < α ≤ 30°.

[0038] The height difference of the inner bottom wall 31 of the drainage trough gradually decreases along the circumference by 2-25mm. The inclined area of ​​the inner bottom wall 31 of the drainage trough is an annular area, and the radial width L, i.e., the difference between the outer radius and the inner radius of the annular area, is related to the radius R of the inner bottom wall 31 of the drainage trough in the following way: R / 5 < L < R.

[0039] like Figure 2 As shown, the outer periphery of the inner bottom wall 31 of the drainage trough is connected to the side wall 32 of the drainage trough by a rounded transition. By making the outer periphery of the inner bottom wall 31 of the drainage trough and the side wall 32 of the drainage trough a smooth transition connection, which can be a rounded connection or a diagonal transition connection, dead angles can be avoided at the connection between the outer periphery of the inner bottom wall 31 of the drainage trough and the side wall of the drainage trough. This prevents food residue from accumulating at the connection between the inner bottom wall 31 of the drainage trough and the side wall 32 of the drainage trough, and prevents food residue from accumulating in the drainage trough and being unable to drain.

[0040] Furthermore, the waste disposer also includes a drain outlet 33, which is disposed on the side wall 32 of the drainage trough. The drain outlet 33 communicates with the inner bottom wall 31 of the drainage trough. The drainage trough 3 gradually descends clockwise or counterclockwise from one side of the drain outlet 33 to the other side of the drain outlet, and then continues to gradually descend from the other side of the drain outlet 33 back to one side of the drain outlet, i.e., the highest point of the inner bottom wall of the drainage trough. Alternatively, the area between the drain outlet and the center of the drainage trough is a sloping structure that slopes downward from the center of the drainage trough to the drain outlet 33, and the sloping structure smoothly transitions to the highest and lowest points of the bottom circumference of the drainage trough.

[0041] A water-retaining wall 311 is provided on one side of the inner bottom wall 31 corresponding to the drain outlet 33. The water-retaining wall 311 is formed by the height difference between the highest and lowest points of the inner bottom wall 31 as it gradually decreases in the circumferential direction. The water-retaining wall 311 can block the flow of water in the circumferential direction, increasing the flushing force of the water flow on food residue. At the same time, the water-retaining wall 311 is located on the side of the inner bottom wall 31 of the drainage trough corresponding to the drain outlet 33, which can block food residue and guide it into the drain outlet for discharge. The water-retaining wall 311 smoothly transitions with the inner bottom wall 31 of the drainage trough, which can prevent food residue from accumulating near the drain outlet 33.

[0042] Furthermore, the grinding chamber is equipped with a grinding assembly 2, which is located above the drainage trough 3. The height of the inner bottom wall 31 of the drainage trough gradually decreases along the rotation direction of the grinding assembly 2. Preferably, the water-retaining wall 311 is located on the side of the inner bottom wall 31 of the drainage trough corresponding to the drain outlet 33, which gradually decreases from the rotation direction of the grinding assembly 2. That is, the water-retaining wall 311 forms a cross-section with a height difference between its highest and lowest points as the inner bottom wall 31 gradually decreases along the rotation direction of the grinding assembly 2.

[0043] Generally, the grinding component 2 of the existing garbage disposal rotates clockwise. Therefore, the height of the bottom wall 31 inside the drainage trough gradually decreases clockwise. The drain outlet 33 is connected to the lowest point of the bottom wall 31 inside the drainage trough, and one side of the drain outlet 33 is adjacent to the highest point of the bottom wall 31 inside the drainage trough, which gradually decreases clockwise.

[0044] This invention sets the height of the inner bottom wall 31 of the garbage disposal drain 3 to gradually decrease clockwise or counterclockwise along the circumference. When the grinding component 2 rotates, the inner bottom wall 31 of the drain 3 cooperates with the grinding component 2, which increases the water flow pressure in the drain 3, thereby increasing the drainage pressure at the drain outlet. This effectively reduces the amount of food waste residue and increases the drainage pressure at the drain outlet, thus accelerating the discharge speed of food waste.

[0045] Preferably, the bottom wall 31 of the drainage trough is annular, and the inner bottom wall 31 of the drainage trough gradually decreases in height along the rotation direction of the grinding component 2 with the center of the bottom wall as the center. The drainage trough 3 has a barrel-shaped structure, and a mounting hole 312 is provided in the middle of the inner bottom wall 31 of the drainage trough. The motor 4 is located below the drainage trough 3, and the drive shaft of the motor 4 passes through the mounting hole 312 of the drainage trough 3 and is axially connected to the grinding component 2 to provide power to the grinding component 2 and drive the grinding component 2 to rotate and grind food waste.

[0046] The grinding assembly 2 includes a blade disc 21, which has a radially arranged impeller (not shown in the figure) extending toward the drainage groove 3. Because the blade disc 21 has a radially arranged impeller, this structure facilitates the discharge of food residue during drainage. When the grinding assembly 2 rotates and grinds, the impeller drives the water flow to flush away any food residue that may remain in the drainage groove 3.

[0047] After food waste enters the water storage tank 1, it is ground into residue by the grinding component 2 and enters the drainage tank through the leakage hole on the grinding component's blade. After drainage, the water level drops, and the food residue may get stuck in the gap between the blade and the drainage tank. Due to the rotation of the blade, it can fall into the drainage tank.

[0048] Furthermore, the impeller of the grinding assembly 3 is formed by radially arranged ribs or water-repelling blades. Alternatively, it may be composed of radially arranged protrusions formed by other structures.

[0049] In a more preferred embodiment, a recessed annular waterway (not shown in the figure) is provided along the circumferential direction at the outer peripheral edge of the inner bottom wall 31 of the drainage trough and the adjacent side wall 32 of the drainage trough. The sewage outlet 33 is provided on the side wall 32 of the drainage trough and communicates with the annular waterway.

[0050] Furthermore, the depth of the annular waterway gradually decreases clockwise or counterclockwise along the circumference, with the decreasing direction consistent with the rotation direction of the grinding assembly. The drain outlet 6 is located on the side wall of the drainage trough and connects to the lowest point of the annular waterway 12, with one side adjacent to the shallowest point of the annular waterway. And / or the width of the annular waterway gradually widens clockwise or counterclockwise along the circumference, with the changing direction consistent with the rotation direction of the grinding assembly. The sewage outlet 33 is located at the widest point of the annular waterway, with one side adjacent to the narrowest point of the annular waterway.

[0051] The annular waterway can be formed by gradually sloping from the center of the inner bottom wall 31 of the drainage trough towards the side wall 32 of the drainage trough, and cooperating with the side wall 32 of the drainage trough.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
