Description

Technical Field

[0001] This invention relates to the field of waste disposal technology, and in particular to an anti-clogging kitchen waste disposer. Background Technology

[0002] Kitchen waste, mostly organic matter, easily breeds bacteria, produces unpleasant odors, and is complex in composition, making it difficult to sort. It is a major component of household waste and naturally requires corresponding products for processing. With the implementation of garbage sorting policies in various regions, the sales of sorting garbage bins and garbage disposers have increased significantly, and food waste disposers are being purchased and used by more and more users. There are various types of existing food waste disposers, among which the direct-discharge type grinds the waste and discharges it directly into the sewer, providing users with a certain degree of convenience. Direct-discharge type garbage disposers generally consist of a corrosion-resistant grinding chamber, stainless steel grinding hammers, and stainless steel grinding discs. It uses a high-speed rotating permanent magnet motor to drive the grinding discs in the grinding chamber. Food waste collides with each other under centrifugal force, grinding it into fine particles in a very short time and flushing it out of the pipe with the water flow, thus achieving the effects of cleaning the environment and eliminating odors, providing great convenience to people's lives. However, existing food waste disposers often suffer from sewer blockage problems. Once the drainage becomes blocked, it can cause users to be unable to use the food waste disposer normally or even the sink. Therefore, how to effectively design anti-clogging structures for food waste disposal and improve anti-clogging performance has always been a difficult problem hindering the development of food waste disposers. Furthermore, existing food waste disposers have poor processing capabilities for coarse-fiber food waste, indicating significant room for improvement. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an anti-clogging kitchen waste processor that shears ground kitchen waste under the action of water flow driven by centrifugal ejection from a pump impeller, in light of the above-mentioned existing technology.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: The anti-clogging kitchen waste disposer includes a housing and a grinding chamber disposed within the housing. The grinding chamber has a feeding port at the top and a discharge port at the bottom. A grinding disc rotating under the drive of a motor is installed inside the grinding chamber. The invention is characterized in that: a fixed shear and a turbine shear are installed inside the grinding chamber, which cooperate with each other. The fixed shear and the turbine shear are distributed circumferentially along the inner wall of the grinding chamber and form a shearing area below the outer periphery of the grinding disc. A pump wheel that rotates synchronously with the grinding disc is installed at the bottom of the grinding disc. A circumferentially distributed material drop holes are opened on the inner periphery of the fixed shear. The turbine shear has an annular blade holder located below the inner periphery of the fixed shear. A rotating blade head that rotates under the drive of the centrifugal water flow ejected by the pump wheel is installed on the annular blade holder. The rotating blade head is located below the material drop holes and is spaced apart circumferentially along the annular blade holder.

[0005] Preferably, each of the rotating cutter heads includes a shank and a blade, the bottom of the shank being fixed to an annular cutter holder, and the blade being rotatably disposed at the head of the shank.

[0006] In order to enable the water flow centrifugally ejected by the pump impeller to smoothly drive the rotating cutter head to rotate, the blade has a vertically arranged water flow impact surface and a cutting surface located at the top of the water flow impact surface.

[0007] In order to ensure that the water ejected by the centrifugal impeller can flow smoothly to the rotating cutter head, the annular cutter holder has water passage holes distributed circumferentially, and each water passage hole corresponds to a rotating cutter head on its radial outer side.

[0008] The fixed shear and the turbine shear can have various installation structures. Preferably, the fixed shear is fixed to the inner wall of the grinding chamber, and the annular blade holder of the turbine shear is fixed to the fixed shear or to the inner wall of the grinding chamber. Alternatively, the annular blade holder is movably disposed on the fixed shear or the grinding chamber and can rotate circumferentially relative to the fixed shear.

[0009] The pump impeller can have various structures. Preferably, the pump impeller includes a pump impeller fixing disc and pump impeller blades. The pump impeller blades are distributed circumferentially. The upper end of the pump impeller blades is mounted on a grinding disc, and the lower end of the pump impeller blades is mounted on the pump impeller fixing disc. The turbine is sheared on the outer periphery of the pump impeller blades.

[0010] Further preferably, the grinding chamber includes an upper grinding cover and a lower grinding cover connected to each other. The feeding port is located at the top of the upper grinding cover, and the discharge port is located on the side of the lower grinding cover and below the grinding disc. The grinding disc is located inside the lower grinding cover, and the motor is located below the lower grinding cover. The motor's output shaft passes vertically upward through the lower grinding cover and is connected to the grinding disc. The fixing shear is fixed to the inner circumferential wall of the lower grinding cover. The upper and lower grinding covers allow for smooth installation of the grinding disc.

[0011] In order to limit the fixed shear on the grinding cover, a limiting protrusion is provided on the inner peripheral wall of the grinding cover, and a limiting groove is opened on the outer peripheral part of the fixed shear, and the limiting protrusion is inserted into the corresponding limiting groove.

[0012] Further preferably, a lower grinding ring is installed on the upper part of the inner peripheral wall of the lower grinding cover, and the fixed shear is installed at the bottom of the lower grinding ring. A water-passing gap is left between the outer peripheral edge of the grinding disc and the lower grinding ring. After setting the lower grinding ring, the grinding effect can be improved, and most of the water falling on the grinding disc enters the shearing area below through the water-passing gap under the action of centrifugal force.

[0013] In order to allow some of the water that falls onto the grinding disc to fall off through the grinding disc, a drainage hole is made on the grinding disc.

[0014] To install the garbage disposer on the sink, an installation assembly is installed at the feed inlet.

[0015] Compared with the prior art, the advantages of the present invention are as follows: the anti-clogging food waste disposer has a fixed shear and a turbine shear arranged below the grinding disc. The turbine shear has a rotating blade. When the food waste ground by the grinding disc falls into the shearing area below, the rotating blade rotates under the drive of the rotating water flow thrown by the centrifugal pump disc to shear the falling food waste, especially effectively shearing fibrous waste, thereby greatly improving the processing capacity of fibrous food waste and improving the anti-clogging performance.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 5 As shown, the anti-clogging food waste disposer of this embodiment includes a housing 1 and a grinding chamber disposed within the housing. The grinding chamber includes an upper grinding cover 2 and a lower grinding cover 3 connected to each other. A grinding disc 4 is installed inside the lower grinding cover 3, and a motor 5 is installed below the lower grinding cover 3. The output shaft of the motor 5 passes vertically upward through the lower grinding cover 3 and is connected to the grinding disc 4. The grinding disc 4 rotates under the drive of the motor 5. A feeding port 21 is opened at the top of the upper grinding cover 2, and a mounting assembly 10 is installed at the feeding port 21. A discharge port 31 is opened on the side of the lower grinding cover 3, located below the grinding disc 4. The waste discharged from the discharge port 31 enters the sewer. The above structure is the conventional structure of existing food waste disposers and will not be described in detail here.

[0028] like Figures 6 to 9 As shown, a fixed shear 6 and a turbine shear 7 are installed inside the lower grinding cover 3, cooperating with each other. The fixed shear 6 and the turbine shear 7 are distributed circumferentially along the inner wall of the grinding chamber, forming a shearing area below the outer periphery of the grinding disc 4. The inner periphery of the fixed shear 6 has circumferentially distributed material dropping holes 61. The fixed shear 6 is fixed to the inner periphery of the lower grinding cover 3. Specifically, a limiting protrusion 32 protrudes inward on the inner periphery of the lower grinding cover 3, and a limiting groove 62 is opened on the outer periphery of the fixed shear 6. The limiting protrusion 32 is engaged in the corresponding limiting groove 62.

[0029] The turbine shear 7 has an annular cutter holder 71 and rotating cutter heads 72 mounted on the annular cutter holder 71. The annular cutter holder 71 is located below the inner periphery of the fixed shear 6 and is fixed to the fixed shear 6. The rotating cutter heads 72 are located below the material discharge hole 61 and are distributed circumferentially along the annular cutter holder 71. The annular cutter holder 71 has water passage holes 711 distributed circumferentially. Each water passage hole 711 has a rotating cutter head 72 corresponding to its radial outer side, so that water can pass through the water passage hole 711 and impact the rotating cutter head 72, causing the rotating cutter head 72 to rotate.

[0030] In this embodiment, each rotating cutter head 72 includes a handle 721 and a blade 722. One handle 721 and one blade 722 constitute a group, and there are three groups in each rotating cutter head 72. The bottom of the handle 721 is fixed on the annular cutter seat 71, and the blade 722 is rotatably mounted on the head of the handle 721. In addition, the blade 722 has a vertically arranged water flow impact surface 7221 and a cutting surface 7222 located on top of the water flow impact surface. After the water flow impacts the water flow impact surface 7221, it can drive the blade 722 to rotate, thereby cutting the kitchen waste. In particular, fibrous waste that has been ground by the grinding disc 4 is effectively cut after falling from the discharge hole 61, thereby greatly improving the processing capacity of fibrous kitchen waste and further ensuring the anti-clogging performance.

[0031] like Figure 6 and Figure 10 As shown, a pump wheel disc 8 is installed at the bottom of the grinding disc 4. Driven by the motor 5, the pump wheel disc 8 rotates synchronously with the grinding disc 4. In this embodiment, the pump wheel disc 8 includes a pump wheel fixing disc 81 and pump wheel blades 82. The pump wheel blades 82 are spaced circumferentially. The upper ends of the pump wheel blades 82 are mounted on the grinding disc 4, and the lower ends are mounted on the pump wheel fixing disc 81. The pump wheel blades 82 and the grinding disc 4 can be connected by insert riveting or by welding. The pump wheel blades 82 and the pump wheel fixing disc 81 can also be connected by insert riveting or by welding. The ground kitchen waste is smoothly discharged through the discharge port 31 under the centrifugal force of the pump wheel, significantly improving the anti-clogging capability. The turbine shear 7 is located on the outer periphery of the pump wheel blade 82. When water is stored in the grinding chamber, the pump wheel blade 82 rotates at high speed with the motor 5, which drives the water flow inside the grinding chamber to rotate at high speed. The water flow centrifugally thrown out by the pump wheel disc 8 impacts the water flow impact surface 7221 of the rotating cutter head 72, causing the rotating cutter head 72 to rotate. It cooperates with the fixed shear 6 to achieve fiber shearing.

[0032] like Figure 6 and Figure 7As shown, an upper grinding ring 92 is installed on the inner circumferential wall of the lower part of the grinding upper cover 2, and a lower grinding ring 91 is installed on the upper part of the inner circumferential wall of the grinding lower cover 3. The grinding effect can be improved by setting the upper grinding ring 92 and the lower grinding ring 91. The working principle of the lower grinding ring 91 and the upper grinding ring 92 can be referred to the existing garbage disposal unit, and will not be described in detail here.

[0033] In this embodiment, a water passage gap 11 is left between the outer periphery of the grinding disc 4 and the lower grinding ring 91, and a water drop hole 41 is opened on the grinding disc 4. During operation, water enters the grinding disc 4 from the feed port 21. As the grinding disc 4 rotates under the action of the motor 5, most of the water on the grinding disc 4 flows to the lower shearing area through the water passage gap 11 under the action of centrifugal force. A small portion of the water flows downward through the water drop hole 41 on the grinding disc 4 and enters the pump wheel disc 8 area. The water falling into the pump wheel disc 8 area is thrown out under the action of the centrifugal force of the pump wheel to form a water flow that impacts the rotating cutter head 72.
