Description

Technical Field

[0001] The invention belongs to the technical field of kitchen appliances and relates to a kitchen waste treatment device. Background Art

[0002] With the acceleration of urbanization and the improvement of people's living standards, the amount of kitchen waste is increasing, which has caused great pressure on the environment. Kitchen waste mainly includes food residues, fruit peels, vegetable leaves and other organic waste. If it is not properly handled, it will not only cause a waste of resources, but also cause environmental pollution problems. The most common way to deal with it is to discard it with domestic garbage, which is not only troublesome, but also emits a foul odor after being discarded in the garbage station, affecting the surrounding environment. Therefore, it is imperative to develop efficient and environmentally friendly kitchen waste treatment technology.

[0003] In recent years, food waste disposers have become increasingly popular as a common device in household kitchens. This type of device can be installed under the sink. The built-in mechanical device crushes the food waste and discharges it through the pipe with the water flow, which greatly simplifies the daily treatment process of food waste. Compared with the traditional method of discarding it with domestic waste, the use of food waste disposers can effectively reduce garbage accumulation, reduce the pressure of urban garbage disposal, and help improve the resource utilization rate of food waste.

[0004] Most of the food waste disposers on the market currently use the technical principle of centrifugal collision crushing. This working method uses the centrifugal force generated by high-speed rotation to make the food waste collide with the blades in the crushing chamber, thereby achieving the purpose of crushing. However, this traditional centrifugal collision crushing method has certain limitations: on the one hand, due to the relatively low crushing efficiency, it takes a long time to process a large amount of food waste; on the other hand, during the crushing process, due to the violent collision between the blades and the garbage, a large noise will be generated, affecting the user experience. Summary of the invention

[0005] The object of the present invention is to provide a kitchen waste treatment device, which uses a grinding and crushing method to treat kitchen waste, with higher crushing efficiency and less noise during operation.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a kitchen waste treatment device, comprising a shell, the shell is divided into an electrical chamber and a grinding chamber, a grinding roller is rotatably connected in the grinding chamber, a grinding motor for driving the grinding roller to rotate is installed in the electrical chamber, a plurality of grinding convex teeth are arranged on the outer periphery of the grinding roller, a J-shaped extrusion plate matched with the grinding roller is movably arranged in the grinding chamber, the J-shaped extrusion plate gradually approaches the side wall of the grinding roller from top to bottom, the lower end of the J-shaped extrusion plate is located at the lower end of the grinding roller and is connected to the inner wall of the grinding chamber, a support spring is arranged between the upper part of the J-shaped extrusion plate away from the grinding roller and the inner wall of the grinding chamber, an inlet is opened at the upper end of the shell above between the J-shaped extrusion plate and the grinding roller, a collection funnel is arranged in the grinding chamber below the side of the grinding roller away from the J-shaped extrusion plate, and the lower end of the collection funnel is connected with a sewer connection pipe extending downward from the shell;

[0007] The two inner walls at the top of the grinding chamber are slidably connected with a baffle plate capable of blocking the input port, a driving motor for driving the baffle plate to slide is installed in the electrical chamber, a flushing pipe is provided at the lower end of the baffle plate along its length direction, a plurality of flushing holes distributed along its length direction are opened at the lower end of the flushing pipe, an instant heating cylinder is provided in the grinding chamber away from the J-shaped extrusion plate, the flushing pipe is connected to the outlet end of the instant heating cylinder through a water outlet hose, the inlet end of the instant heating cylinder is connected to a solenoid valve, and the free end of the solenoid valve is connected to a water inlet interface extending out of the shell.

[0008] By adopting the above technical solution, after the kitchen waste is put into the grinding chamber from the input port, the waste is accumulated between the J-shaped extrusion plate and the grinding roller, and the grinding motor is started to drive the grinding roller to rotate. The grinding roller rotates to grind and scrape the waste on the J-shaped extrusion plate backward little by little, and finally forms fragments that fall into the aggregate hopper and are discharged from the sewer connection pipe. If harder waste (such as bones) is encountered, the J-shaped extrusion plate is pushed to compress the support spring during the rotation of the grinding roller, so that the bones are further stuck between the J-shaped extrusion plate and the grinding roller, so that the grinding roller can grind and crush them little by little, and the grinding will not rotate between the J-shaped extrusion plate and the grinding roller, which will cause difficulty in grinding and noise.

[0009] After the kitchen waste is ground and crushed, the solenoid valve opens, allowing tap water to enter the hot heating cylinder for heating, and the driving motor drives the baffle plate to move the flushing pipe, spraying hot water to the J-shaped extrusion plate and grinding roller for flushing. During the process, the grinding roller also rotates, and part of the hot water also enters the oil separation tank from the bottom along the filtrate hole and the liquid guide channel for flushing, and finally rinses the equipment in the grinding chamber. The water that completes the flushing is discharged from the sewer connection pipe.

[0010] The present invention is further configured as follows: an oil separation groove is arranged below the J-shaped extrusion plate in the grinding chamber, a filtrate hole is provided on the side wall of the grinding chamber between the J-shaped extrusion plate and the grinding roller, the shell is provided with a liquid guide channel connecting the filtrate hole with the lower part of the oil separation groove on the outer side of the grinding chamber, a liquid outlet is arranged at the lower part of the oil separation groove close to the collecting funnel, a guide channel is connected between the oil separation groove and the collecting funnel, the guide channel is used to connect the liquid outlet with the collecting funnel, an oil collecting funnel is arranged on the side of the oil separation groove away from the collecting funnel, an oil outlet connected to the oil collecting funnel is arranged on the upper side of the oil separation groove, and the lower end of the oil collecting funnel is connected to an oil drain pipe passing through the shell downward.

[0011] By adopting the above technical scheme, after the kitchen waste is put into the grinding chamber from the input port, the waste is first accumulated between the J-shaped extrusion plate and the grinding roller, and the oil and liquid in the waste enter the oil separation tank from the bottom through the filtrate hole and the liquid guide channel. In the oil separation tank, the oil floats on the upper layer. When there is a certain amount of liquid in the oil separation tank, the resistance baffle is pushed to open the liquid outlet, so that the liquid enters the gathering funnel through the liquid outlet and the guide channel, and is finally discharged through the sewer connecting pipe, while the oil on the upper layer is discharged into the oil collecting funnel through the oil outlet, and is finally collected in the oil bottle through the oil drain pipe.

[0012] The present invention is further configured as follows: a resistance baffle rotating in a vertical plane is rotatably connected to one side of the oil separation tank close to the collecting funnel, and the resistance baffle is used to block the liquid outlet so that it does not open when the liquid thrust is small.

[0013] The present invention is further configured as follows: a support seat is provided at the lower end of the shell, the support seat is provided with an oil receiving groove and a water connection groove with a front end opening, the oil drain pipe extends downward into the oil receiving groove, and the water connection pipe extends downward into the water connection groove.

[0014] The present invention is further configured as follows: a threaded drive rod perpendicular to the electrical chamber is rotatably connected to the upper portion of the grinding chamber away from the J-shaped extrusion plate, a power output shaft of the drive motor is connected to one end of the threaded drive rod, the front and rear sections of the threaded drive rod have opposite spiral directions of threads, the front and rear sections of the threaded drive rod are both threadedly connected to threaded sleeves, and a push-pull arm is rotatably connected between each threaded sleeve and the baffle plate.

[0015] The present invention is further configured as follows: a safety filter is provided above the grinding roller and the J-shaped extrusion plate in the grinding chamber, and the safety filter is located below the baffle plate.

[0016] The present invention is further configured as follows: the safety filter is located at a side inclined downward toward the J-shaped extrusion plate.

[0017] The present invention is further configured as follows: a spiral electric heating tube is provided in the instant heating cylinder.

[0018] In summary, the present invention has the following beneficial effects:

[0019] First, the present invention adopts a rolling grinding method to crush kitchen waste, and gradually scrapes the waste into pieces and discharges them by extrusion and grinding. Compared with the existing centrifugal collision crushing method, the crushing speed is faster, and no collision occurs during the process, so there will be no noise generated by the collision. The noise during the work process is smaller, and the user experience is better;

[0020] Secondly, when the present invention is grinding and crushing, if it encounters harder garbage (such as bones), it will push the J-shaped extrusion plate to move and deform, so that the bones are stuck between the J-shaped extrusion plate and the grinding roller and are ground and crushed little by little, without rotating between the J-shaped extrusion plate and the grinding roller, which makes it difficult to grind and makes noise;

[0021] Third, in order to solve the problem that a large amount of grease in kitchen waste may cause pipe blockage when poured into the sewer, the present invention also has an oil separation function, which can separate and collect the oil in the kitchen waste separately to prevent the sewer from being blocked, and the collected oil can be used to make products such as biodiesel and soap, thereby realizing the effective recycling of resources;

[0022] Fourthly, the present invention automatically cleans the grinding chamber by sliding the baffle plate after use to prevent garbage from adhering to the grinding chamber, and after cleaning, the baffle plate automatically blocks the input port to prevent objects from accidentally falling into the input port.

A safety filter 10 is provided above the grinding roller 4 and the J-shaped extrusion plate 7 in the grinding chamber 3. The safety filter 10 is a strip-shaped grille, and the aperture is so large that a human hand cannot pass through, so as to prevent a human hand from reaching in and causing danger. The safety filter 10 is located on the side facing the J-shaped extrusion plate 7 and is tilted downward. When there is larger garbage that cannot pass through, it is accumulated on one side of the safety filter 10 for easy removal. A collection funnel 11 is provided below the side of the grinding roller 4 away from the J-shaped extrusion plate 7 in the grinding chamber 3. The lower end of the collection funnel 11 is connected to a water connection pipe 12 extending downward from the housing 1. The water connection pipe 12 is used to connect to the kitchen drain.

[0034] The two inner walls at the top of the grinding chamber 3 are slidably connected with a baffle plate 13 that can block the input port 9. The two inner walls at the top of the grinding chamber 3 are both provided with slide rails 14 slidably connected to the baffle plate 13. The safety filter 10 is located below the baffle plate 13. A driving motor 15 for driving the baffle plate 13 to slide is installed in the electrical chamber 2.

The power output shaft of the driving motor 15 is connected to one end of the threaded driving rod 16. The front and rear sections of the threaded driving rod 16 have opposite spiral directions of the threads. The front and rear sections of the threaded driving rod 16 are both threadedly connected with a threaded sleeve 17. A push-pull arm 18 is rotatably connected between each threaded sleeve 17 and the baffle plate 13.

The free end of the solenoid valve 24 is connected to a water inlet interface 25 extending out of the shell 1. The flushing pipe 19 flushes the grinding chamber 3 as the baffle plate 13 slides.

[0036] An oil-contamination separation groove 26 is provided below the J-shaped extrusion plate 7 in the grinding chamber 3, a plurality of filtrate holes 27 are provided on the side wall of the grinding chamber 3 between the J-shaped extrusion plate 7 and the grinding roller 4, and a liquid guide channel 28 is provided on the outer side of the grinding chamber 3 for connecting the filtrate holes 27 and the lower part of the oil-contamination separation groove 26, so that the liquid between the J-shaped extrusion plate 7 and the grinding roller 4 flows into the oil-contamination separation groove 26, and a liquid outlet 29 is provided at the lower part of the oil-contamination separation groove 26 near the collecting funnel 11. A resistance baffle 30 rotating in a vertical plane is rotatably connected to the side of the oil-contamination separation groove 26 near the collecting funnel 11, and the resistance baffle 30 is used to block the liquid outlet 29 so that it does not open when the liquid thrust is small. The liquid in the oil-contamination separation groove 26 can push the resistance baffle 30 to open the liquid outlet 29 only when there is a certain amount of liquid, so as to prevent the oil from being discharged from the liquid outlet 29.

[0037] A flow guide channel 31 is connected between the oil-contamination separation tank 26 and the collecting funnel 11. The flow guide channel 31 is used to connect the liquid outlet 29 and the collecting funnel 11. The liquid after oil separation flows into the collecting funnel 11 through the flow guide channel 31. An oil collecting funnel 32 is arranged on the side of the oil-contamination separation tank 26 away from the collecting funnel 11. An oil outlet 33 connected to the oil collecting funnel 32 is opened on the upper side of the oil-contamination separation tank 26. The density of oil is higher than that of water bottom, so it will float on the upper layer of water and can be discharged from the oil outlet 33. The lower end of the oil collecting funnel 32 is connected to an oil drain pipe 34 that passes downward through the shell 1. A support seat 35 is provided at the lower end of the shell 1. The support seat 35 is provided with an oil receiving groove 36 with a front end opening and a water discharge connecting groove 37. The oil discharge pipe 34 extends downward into the oil receiving groove 36. The unused oil bottle is placed in the oil receiving groove 36, and the oil discharge pipe 34 is extended into the bottle mouth, so that it can be used to collect waste oil. The water discharge connecting pipe 12 extends downward into the water discharge connecting groove 37, and the water discharge connecting pipe 12 is connected to the water outlet in the water discharge connecting groove 37 through a sewage pipe.

[0038] Working principle: After the kitchen waste is put into the grinding chamber 3 from the input port 9, the waste is first accumulated between the J-shaped extrusion plate 7 and the grinding roller 4, and the oil and liquid in the waste enter the oil separation tank 26 from the bottom through the filtrate hole 27 and the liquid guide channel 28. In the oil separation tank 26, the oil floats on the upper layer. When there is a certain amount of liquid in the oil separation tank 26, the resistance baffle 30 is pushed to open the liquid outlet 29, so that the liquid enters the collecting funnel 11 through the liquid outlet 29 and the guide channel 31, and is finally discharged through the sewer connection pipe 12, while the upper layer of oil is discharged into the oil collecting funnel 32 through the oil outlet 33, and is finally collected in the oil bottle through the oil discharge pipe 34;

[0039] Then, the grinding motor 5 is started to drive the grinding roller 4 to rotate. The grinding roller 4 rotates to grind and scrape the garbage on the J-shaped extrusion plate 7 backwards little by little, and finally the broken pieces fall into the collecting funnel 11 and are discharged from the sewer connection pipe 12. If harder garbage (such as bones) is encountered, the J-shaped extrusion plate 7 is pushed to compress the support spring 8 during the rotation of the grinding roller 4, so that the bones are further stuck between the J-shaped extrusion plate 7 and the grinding roller 4, so that the grinding roller 4 can grind and crush them little by little, and the grinding will not rotate between the J-shaped extrusion plate 7 and the grinding roller 4, which will make it difficult to grind and make noise;

[0040] After the kitchen waste is ground and crushed, the solenoid valve 24 opens to allow tap water to enter the thermal heating cylinder for heating, and the driving motor 15 drives the baffle plate 13 to drive the flushing pipe 19 to move, spraying hot water to the J-shaped extrusion plate 7 and the grinding roller 4 for flushing. During the process, the grinding roller 4 also rotates, and part of the hot water also enters the oil separation tank 26 from the bottom along the filtrate hole 27 and the liquid guide channel 28 for flushing, and finally the equipment in the grinding chamber 3 is flushed clean, and the water after the flushing is finally discharged from the sewer connection pipe 12.

[0041] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0042] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
