Double-layer grinding mechanism of food waste disposer

Abstract

The utility model discloses a double-layer grinding mechanism of a food waste disposer, which relates to the technical field of food waste disposers, and comprises a water inlet pipe, and the end part of the water inlet pipe is fixedly connected with a disposer body. With the rotation of the fixed frustum, the knife edge of the crushing knife cuts and grinds the kitchen garbage, so that the garbage is continuously crushed and then slides down from the side surface of the fixed frustum, and the vertical design of the crushing knife enables the blade to only bear a shearing force perpendicular to the blade during cutting, so that the pressure from the top is reduced, and the crushing efficiency is improved. In this way, the blades do not deform during use and do not bend downwards due to the force of kitchen garbage pressed downwards from the top, meanwhile, due to the design of the fixed frustum, crushed objects can slide down rapidly along with water flow, the rotating shaft is prevented from blocking falling of the crushed objects, the garbage flowing rate is increased, and blocking is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of food waste disposers, in particular to a double-layer grinding mechanism of a food waste disposer. Background Art

[0002] With the continuous development of urban life, people gradually found that food waste in the kitchen has become a thorny problem in life. When using a funnel with good filtering effect, the filtration speed is too slow. Conversely, when pouring water into the sink, there will be a lot of larger debris blocking the pipe, which often causes pipe blockage and affects the life and diet of citizens.

[0003] Some families now install food waste disposers at the bottom of the kitchen sink, which can crush the poured food waste, helping the food waste to flow into the sewer along the water flow without clogging the pipes. However, the single-layer grinding of the food waste disposer will be entangled with fibers after long-term use, which will affect the rotation speed and service life, requiring maintenance, and reduce the food waste treatment effect, making the user experience worse, which is not conducive to the promotion and application of food waste disposers. Therefore, this patent proposes a double-layer grinding food waste disposer that is easy to maintain to solve such problems. Utility Model Content

[0006] Preferably, the inner rotating tube is located in the middle of the upper limit ring and the lower limit ring, and four crushing knives are evenly arranged on the inner wall of the inner rotating tube, and the crushing knives are fixed obliquely.

[0011] Preferably, the outer body of the processor body is a stainless steel round tube.

[0012] Compared with the related art, the double-layer grinding mechanism of the food waste disposer provided by the utility model has the following beneficial effects:

[0013] The utility model provides a double-layer grinding mechanism for a food waste disposer, wherein kitchen waste is poured into the middle part of an inner rotating tube, and as the fixed cone rotates, the blade of the crushing knife cuts and grinds the kitchen waste, so that the waste is continuously crushed and then slides down from the side of the fixed cone. The vertical design of the crushing knife enables the blade to be subjected to only a shear force perpendicular to the blade during cutting, thereby reducing the pressure from the top. In this way, the blade will not be deformed during use, and will not bend downward due to the force of the kitchen waste pressing downward from the top. At the same time, the design of the fixed cone allows the crushed material to slide down quickly with the water flow, thereby avoiding the obstruction of the rotating shaft to the falling of the crushed material, thereby increasing the flow rate of the waste and avoiding blockage.

[0014] The utility model provides a double-layer grinding mechanism for a food waste disposer. By leaving a suitable spacing between the slope of the fixed cone and the bottom of the inner rotating tube, smaller debris can flow out through the gap between them, and there is no need to grind all the food waste, thereby improving the utilization efficiency of the food waste disposer, accelerating the falling of impurities, and making the grinded food waste run faster in the disposer, and then fall on the top surface of the centrifugal disk. As the push plate moves, it is centrifuged to the middle of the water outlet pipe under the action of the water flow and finally enters the sewer pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Reference Figure 3 The inner rotating tube 301 is located in the middle of the upper limit ring 303 and the lower limit ring 304, and four crushing knives 306 are evenly arranged on the inner wall of the inner rotating tube 301, and the crushing knives 306 are fixed obliquely; specifically, the inner rotating tube 301 rotates in the middle of the upper limit ring 303 and the lower limit ring 304, and the rotation of the inner rotating tube 301 causes the crushing knives 306 to rotate to crush the kitchen waste falling in the middle. The obliquely placed crushing knives 306 can prevent the blades from being overly stressed and will not deform.

[0022] Reference Figure 2 and Figure 3 , the two push plates 309 are placed vertically, and the height of the centrifugal disc 310 is the same as the water outlet pipe 2; specifically, the crushed kitchen waste falls to the top surface of the centrifugal disc 310, and driven by the rotation of the push plate 309, flows in the opposite direction to the water outlet pipe 2 along the radius of the centrifugal disc 310.

[0023] Reference Figure 3 The four crushing knives 306 are placed in an inverted cone shape, and the blades of the crushing knives 306 are inclined inward and to one side; specifically, the four crushing knives 306 are evenly placed to form a shape with an open top to avoid excessive top pressure during crushing.

[0024] Reference Figure 3 The structure of the centrifugal disk 310 is conical, and the bottom end of the inner rotating tube 301 is flush with the waist of the fixed cone 307; specifically, a slope is formed around the centrifugal disk 310 to accelerate the flow of the crushed material.

[0025] Reference Figure 1 and Figure 3 , circular holes are opened on both sides of the middle of the processor body 3, and the height of the water inlet pipe 1 is flush with the bottom of the fixed cone 307; specifically, the height of the water inlet pipe 1 allows the water flow to generate impact force on the crushed material.

[0026] Reference Figure 1 The outer body of the processor body 3 is a stainless steel round tube; specifically, the food waste processor is installed at the bottom of the sink, and the use of stainless steel can extend the service life of the food waste processor.

[0027] The working principle of the utility model is as follows: the drain pipe of the kitchen sink is connected to the inside of the processor body 3, so that the food waste can pass through the food waste processor along the inside of the processor body 3, the motor body 302 and the driving shaft 305 rotate, so that the four crushing knives 306 on the top rotate, and the food waste first enters the middle part of the crushing knives 306, and the larger physical waste is crushed at the bottom of the four crushing knives 306, and the small food waste falls through the gap between the inner rotating tube 301 and the fixed cone 307, and the crushed food waste slides along the side of the fixed cone 307, and the rotation of the fixed cone 307 accelerates the crushing.

The rotating centrifugal disk 310 drives the push plate 309 to centrifuge the crushed materials. At the same time, there is a water inlet pipe 1 on the side of the processor body 3, and water enters the inside of the water inlet pipe 1, so that the crushed materials on the top surface of the centrifugal disk 310 enter the inside of the water outlet pipe 2 along with the water flow and go to the sewer. The upper layer of this food waste processor crushes the food waste, and the lower layer grinds and stirs the crushed materials, and the crushed materials flow out of the kitchen under the action of water flow and centrifugal force, thereby improving the processing efficiency of food waste, avoiding the blockage of the sewer pipe, and extending the service life of the processor.
