A food waste disposer and kitchen equipment using it

Abstract

This invention relates to a food waste disposer and a kitchen appliance using the same. The food waste disposer includes a housing with a grinding chamber inside. The housing has an inlet and a outlet connected to the grinding chamber. A grinding assembly includes a grinding disc arranged horizontally in the grinding chamber, which can rotate around its axis. A cover is disposed in the grinding chamber, covering the grinding disc from top to bottom. The top of the cover has an opening corresponding to the inlet, and there is a gap between the inner wall of the cover and the periphery of the grinding disc. The cover can rotate around its axis, and the grinding disc can also rotate around its axis. This increases the relative movement of the grinding disc and the cover compared to a method where only the grinding disc rotates, thereby enhancing the impact and friction on the food waste and improving the grinding effect.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food waste treatment, in particular to a kitchen waste processor and a kitchen equipment applying the same. BACKGROUND

[0002] Kitchen residues are mainly organic matter, which has the characteristics of easy breeding of bacteria, generation of unpleasant odor, and complex composition and difficult sorting, and is the main processing object of household garbage. With the implementation of garbage classification policies in various places, the sales of classified garbage cans and garbage processors have increased significantly, and kitchen waste processors have been purchased and used by more and more users. There are various types of existing kitchen waste processors, among which the direct discharge type garbage processor directly discharges the garbage into the sewer through crushing, which brings certain convenience to the users. The direct discharge type garbage processor is generally composed of a crushing chamber, a stainless steel grinding hammer, a stainless steel grinding disc and the like. It utilizes a high-speed rotating permanent magnet motor to drive the grinding disc in the grinding chamber, and the food waste is impacted under the action of centrifugal force, and is ground into fine particles in a very short time and discharged through the pipeline, thereby achieving the effects of cleaning the environment, removing odor and the like, and providing great convenience for people's life.

[0003] For example, the Chinese utility model patent with the patent number CN202223546707.1 (publication number CN219240733U) discloses a garbage processor, which comprises a shell, a crushing chamber is arranged in the shell, the crushing chamber is provided with a garbage inlet and a sewage discharge port, a crushing piece is rotatably arranged in the crushing chamber, a driving assembly is connected with the crushing piece to drive the crushing piece to rotate, an ozone generating assembly is arranged to discharge ozone into the crushing chamber, and a blocking assembly is arranged to open or close the garbage inlet and / or the sewage discharge port. The garbage processor is provided with a sterilization mode, the garbage inlet and / or the sewage discharge port are closed in the sterilization mode, and the ozone generating assembly is operated to introduce ozone into the crushing chamber.

[0004] However, the above-mentioned patent has the following problems: 1. When feeding from the garbage inlet to the crushing chamber, because the kitchen garbage usually has a certain humidity, it is easy to accumulate at the garbage inlet and not easy to be fed into the crushing chamber; 2. The garbage disposer mainly relies on the rotation of the crushing piece to impact the kitchen garbage for crushing treatment. In the process of rapid rotation of the crushing piece, the kitchen garbage will impact back and forth between the crushing piece and the wall surface of the crushing chamber. The crushed garbage will splash in all directions. Although the first blocking piece is provided at the garbage inlet, the first blocking piece also causes certain difficulty in feeding. The user needs to take out the first blocking piece from the garbage inlet for feeding. Even if the first blocking piece of the patent has elasticity, the user needs to use his hand or a feeding rod to stab the kitchen garbage downward to help feeding, which is more troublesome; 3. Only relying on the rotation of the crushing piece to drive the garbage to impact, the crushing effect on the garbage is poor, and the crushing efficiency is low. SUMMARY

[0005] The first technical problem to be solved by the present application is to provide a kitchen garbage disposer with good crushing effect on garbage in view of the status of the prior art.

[0006] The second technical problem to be solved by the present application is to provide a kitchen garbage disposer capable of guiding the garbage at the feeding port into the crushing chamber in view of the status of the prior art.

[0007] The third technical problem to be solved by the present application is to provide a kitchen garbage disposer capable of closing or opening the feeding port according to needs in view of the status of the prior art.

[0008] The fourth technical problem to be solved by the present application is to provide a kitchen equipment applying the above-mentioned kitchen garbage disposer in view of the status of the prior art.

[0009] The technical scheme adopted by the present application to solve the above-mentioned first technical problem is as follows: a kitchen garbage disposer, comprising:

[0010] a shell, the shell having a crushing chamber inside, the shell being provided with a feeding port and a discharging port in communication with the crushing chamber;

[0011] a grinding assembly, comprising a grinding disc transversely arranged in the crushing chamber, the grinding disc being capable of rotating about its axis;

[0012] characterized in that it further comprises:

[0013] a cover body arranged in the crushing chamber, the cover body covering the grinding disc from top to bottom, the top of the cover body having an opening in communication with the feeding port, and the inner wall surface of the cover body having a gap with the periphery of the grinding disc, the cover body being capable of rotating about its axis.

[0014] In order to drive the cover to rotate, the kitchen garbage disposer further comprises a driving mechanism connected with the cover driving, the driving mechanism comprising a driving member and a second output shaft connected with the driving member driving, the second output shaft being connected with the cover driving through a transmission assembly. The second output shaft can be directly connected with the cover, but the length of the second output shaft needs to be longer, so the second output shaft is connected with the cover through the transmission assembly.

[0015] The transmission assembly can have various structural forms, and is simple in structure. A first gear is mounted on the second output shaft, an annular plate is formed on the outer peripheral wall of the cover and extends outwardly and transversely, a plurality of teeth are arranged on the peripheral wall of the annular plate, the first gear and the teeth are engaged through a transmission structure, and the first gear, the teeth and the transmission structure jointly constitute the transmission assembly.

[0016] The driving member is arranged below the crushing cavity, the second output shaft extends vertically, the first gear is a bevel gear, and the transmission structure can be a plurality of gears engaged with each other. However, a large number of gears are involved, so the transmission structure comprises:

[0017] A first transmission rod is arranged transversely;

[0018] A second gear, which is a bevel gear, is arranged at one end of the first transmission rod and engaged with the first gear;

[0019] A first pulley is arranged at the other end of the first transmission rod;

[0020] A second transmission rod is arranged transversely above the first transmission rod;

[0021] A second pulley is arranged above the first pulley, the second pulley is arranged at one end of the second transmission rod, and the first pulley and the second pulley are connected through a belt transmission;

[0022] A third gear is arranged at the other end of the second transmission rod, the third gear is a bevel gear and is engaged with the teeth, and a through hole is arranged on the housing and locally extends into the third gear. Through the belt transmission, a small number of components can realize the long-distance transmission of the first gear and the teeth.

[0023] In order to reduce the number of components involved, the driving mechanism further comprises a first output shaft connected with the driving member driving, the first output shaft extending into the crushing cavity and being connected with the grinding disc driving. In this way, the driving member is provided with double output shafts, so as to realize the rotation of the cover and the grinding disc, and a driving member does not need to be arranged for the cover and the grinding disc.

[0024] In order to make the cover rotate smoothly, a first bearing is arranged between the top wall surface of the accommodating cavity and the upper surface of the positioning plate, and a second bearing is arranged between the bottom wall surface of the accommodating cavity and the lower surface of the positioning plate. The arrangement of the bearings reduces the friction between the cover and the shell, so that the rotating resistance of the cover is small.

[0025] In order to make the cover rotate smoothly, a first bearing is arranged between the top wall surface of the accommodating cavity and the upper surface of the positioning plate, and a second bearing is arranged between the bottom wall surface of the accommodating cavity and the lower surface of the positioning plate. The arrangement of the bearings reduces the friction between the cover and the shell, so that the rotating resistance of the cover is small.

[0026] In order to reduce the vibration caused by the rotation of the cover, a first gasket is arranged between the top wall surface of the accommodating cavity and the first bearing, and a second gasket is arranged between the bottom wall surface of the accommodating cavity and the second bearing. Because the cover is frequently impacted by kitchen waste during operation, the bearings are fixed on the gaskets, which can play a role in overall shock absorption and noise reduction. The first gasket and the second gasket are made of rubber material.

[0027] In order to further make the cover rotate smoothly, the positioning plate has at least two upper and lower spaced-apart plates, and correspondingly, the accommodating cavity also has at least two upper and lower spaced-apart plates. In this way, the shell positions the cover at multiple positions, further reducing the probability of tilting of the cover during rotation.

[0028] In the above scheme, the positioning plate has two, the upper positioning plate is called the top plate, and the lower positioning plate is called the annular plate. The annular plate is arranged on the outer peripheral wall of the cover and is connected with the driving mechanism.

[0029] In order to further improve the grinding efficiency of the garbage, the inner wall surface of the cover is provided with a grinding block. During the rotation of the cover, the grinding block can also cut the garbage.

[0030] In order to further improve the grinding efficiency of the garbage, the cover is provided with at least two shearing grooves arranged at intervals along the circumferential direction thereof, and the shearing grooves are arranged around the outer periphery of the grinding disc. The shearing grooves can also play a shearing role on the garbage. After being sheared, the garbage flows to the lower part of the crushing cavity from the gap between the cover and the outer periphery of the grinding disc.

[0031] The technical solution adopted by the application to solve the above-mentioned second technical problem is that a feeding pipe capable of rotating around its axis is inserted into the feeding port, and a material guiding structure capable of conveying materials from top to bottom during rotation of the feeding pipe is arranged in the feeding pipe.

[0032] The material guiding structure can have various structural forms, such as a blade arranged in the feeding pipe in a spiral shape along the axial direction of the feeding pipe, or the material guiding structure can include at least two blades arranged along the circumferential direction of the feeding pipe, each blade extending along the axial direction of the feeding pipe, and each blade having an inner side close to the center line of the feeding pipe and an outer side away from the center line of the feeding pipe, the inner side and the outer side extending along the circumferential direction of the feeding pipe. When the feeding pipe rotates, the blades guide the garbage downward.

[0033] The technical scheme adopted by the present application to solve the third technical problem is that a movable ring capable of moving up and down relative to the feeding pipe is inserted into the feeding pipe, and the movable ring is fixed relative to the feeding pipe in the circumferential direction, the upper end of the outer side of each blade is fixed relative to the feeding pipe, and the lower end of the outer side of each blade is connected to the movable ring.

[0034] The movable ring can move downward to a first position and upward to a second position relative to the feeding pipe under the action of the driving assembly, in the state that the movable ring is in the first position, the adjacent two blades are staggered to form a material passing opening for the garbage to pass through, and in the state that the movable ring is in the second position, all the blades are folded to form a structure that transversely blocks the feeding pipe and separates the upper end of the feeding pipe from the crushing cavity.

[0035] In order to be able to feed when the movable ring is in the second position, the blades are flexible members capable of deforming under the action of an external force, at this time, although the blades are folded to block the feeding pipe, the blades can be poked out of the opening by a tool such as a ramming rod to allow the garbage to pass through.

[0036] The driving assembly can have various structural forms, such as an electric push rod directly pushing the movable ring, but in this way, the electric push rod needs to be at least partially arranged in the crushing cavity, which not only occupies the space of the crushing cavity, but also is easily contaminated by the garbage, therefore, the driving assembly includes:

[0037] A first magnetic member embedded in the movable ring;

[0038] A second magnetic member arranged on the housing and located outside the crushing cavity, the second magnetic member being capable of moving up and down relative to the housing, and the second magnetic member and the first magnetic member being magnetically attracted to each other;

[0039] A driving structure arranged on the housing and located outside the crushing cavity, for driving the second magnetic member to move up and down. In this way, only the first magnetic member is arranged in the crushing cavity, the second magnetic member and the driving structure are both arranged outside the crushing cavity, and the first magnetic member is embedded in the movable ring, without occupying additional space of the crushing cavity.

[0040] The driving structure can be an electric push rod, or it can include a motor, a rotating shaft connected to the motor drive, and a traction rope wound on the rotating shaft. The rotating shaft extends laterally, and one end of the traction rope is connected to a second magnetic component.

[0041] A drive mechanism can be provided to rotate the feed pipe. Preferably, the feed pipe and the cover are fixed relative to each other in the circumferential direction. In this way, when the cover rotates, it can drive the feed pipe to rotate synchronously, eliminating the need for a separate mechanism to drive the feed pipe to rotate, thus simplifying the structure.

[0042] In order to automatically control the moving ring to the first position or the second position, the food waste disposer also includes a controller, a noise detector, and a sensor that can detect the power of the drive mechanism. The noise detector and the sensor are electrically connected to the input terminal of the controller, and the drive assembly is electrically connected to the output terminal of the controller. The noise detector is mounted on the housing.

[0043] When the noise detector detects a noise level greater than or equal to the threshold, the drive assembly moves the movable ring to the second position. At this point, the blades can be manually opened to allow material to be fed in. When the noise detector detects a noise level less than the threshold and the sensor detects that the power difference of the drive mechanism per unit time is less than the threshold, the drive assembly moves the movable ring to the second position. At this point, no more waste enters the crushing chamber, the slag guiding is basically finished, and the main task is to grind the waste. The blades block the feed pipe, which reduces external noise.

[0044] The technical solution adopted by the present invention to solve the fourth technical problem mentioned above is: a kitchen appliance, characterized in that: it includes a sink and the above-mentioned food waste disposer, the food waste disposer is located below the sink, the bottom of the sink is provided with a drain outlet, and the drain outlet is connected to the feed inlet of the shell.

[0045] Preferably, the bottom of the water tank is provided with a sludge sweeping device for sweeping garbage into the drain outlet, so that the garbage in the water tank does not need to be manually pushed into the drain outlet.

[0046] The slag-sweeping component can have various structural forms, such as a pusher plate that can move towards or away from the drain outlet. Preferably, the slag-sweeping component includes an annular body and slag-sweeping strips. The annular body surrounds the drain outlet and can rotate around its axis. Multiple slag-sweeping strips are spaced apart circumferentially within the annular body. One end of each slag-sweeping strip is connected to the annular body, and the other end extends spirally towards the center line of the annular body. Thus, when the annular body rotates, the slag-sweeping strips sweep the debris in the water tank towards the drain outlet, preventing debris from accumulating in the water tank.

[0047] In order to make the annular body rotate, the other end of the slag sweeping bar is connected to the feed pipe. In this way, when the feed pipe rotates, it can drive the annular body to rotate, eliminating the need for a separate structure to drive the annular body to rotate, making the structure more concise.

[0048] Compared with the prior art, the advantages of the present invention are as follows: 1. The cover of the present invention can rotate around its axis, and the grinding disc can also rotate around its axis. This increases the relative movement of the grinding disc and the cover compared to the method where only the grinding disc rotates, thereby enhancing the impact and friction on kitchen waste and improving the grinding effect; 2. The present invention inserts a rotatable feed pipe into the feed pipe, and the feed pipe is equipped with a material guiding structure. When feeding, the feed pipe rotates, and the material guiding structure can transport the waste from top to bottom into the crushing chamber, preventing waste from accumulating at the feed inlet; 3. The blades of the material guiding structure of the present invention... The upper end of the outer side is fixed relative to the feed pipe, while the lower end can move up and down with the movable ring. When feeding is needed, the positioning ring moves downward to the first position, and the adjacent two blades are staggered to form a feed inlet for the garbage to pass through, allowing normal feeding. When feeding is not needed, the movable ring moves upward to the second position, and all the blades close together to form a structure that shields the feed pipe. This serves two purposes: firstly, it prevents the impacted garbage from splashing out of the feed inlet, acting as a splash guard; secondly, it isolates some of the noise generated by the food waste processor during operation within the grinding chamber, reducing noise impact on the user.

[0060] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0061] like Figures 1 to 11 As shown, the kitchen equipment of this preferred embodiment includes a sink A and a food waste disposer B, with the food waste disposer B located below the sink A.

[0062] like Figures 3 to 6 As shown, the food waste disposer B includes a housing 1, a grinding assembly, a cover 3, and a drive mechanism. The housing 1 has a grinding chamber 11 inside, and the housing 1 is provided with a feed inlet 12 and a discharge outlet 13 that are connected to the grinding chamber 11. The feed inlet 12 is located at the top of the housing 1, and the discharge outlet 13 is located on the side wall of the housing 1.

[0063] The grinding assembly includes a grinding disc 2 arranged laterally in the grinding chamber 11. The grinding disc 2 can rotate about its axis. The grinding assembly can adopt an existing structure.

[0064] The cover 3 is located in the crushing chamber 11 and can rotate around its axis. The cover 3 covers the grinding disc 2 from top to bottom. The top of the cover 3 has an opening 31 that communicates with the feed inlet 12, and there is a gap 32 between the inner wall of the cover 3 and the periphery of the grinding disc 2. The cover 3 has at least two shearing slots 33 spaced circumferentially around the outer periphery of the grinding disc 2. The shearing slots 33 can also shear the waste. After being sheared, the waste flows from the gap 32 between the cover 3 and the outer periphery of the grinding disc 2 to the lower part of the crushing chamber 11. The inner wall of the cover 3 is provided with grinding blocks 34. During the rotation of the cover 3, the grinding blocks 34 can also cut the waste.

[0065] The drive mechanism can drive both the housing 3 and the grinding disc 2 to rotate. For example... Figure 4 , 6As shown in Figure 9, the driving mechanism includes a driving component 5 and a first output shaft 51 and a second output shaft 52 that are driven and connected to the driving component 5. The first output shaft 51 extends into the grinding chamber 11 and is driven and connected to the grinding disc 2, while the second output shaft 52 is driven and connected to the cover 3 through a transmission assembly. In this way, the driving component 5 is equipped with two output shafts, which can realize the rotation of the cover 3 and the grinding disc 2 without having to set a separate driving component 5 for each of the cover 3 and the grinding disc 2.

[0066] The first gear 53 is mounted on the second output shaft 52. A ring plate 35 extends laterally outward from the outer peripheral wall of the cover 3. A ring of teeth (not shown in the figure) is provided on the peripheral wall of the ring plate 35. The first gear 53 and the teeth mesh with each other through the transmission structure. The first gear 53, the teeth and the transmission structure together constitute the transmission component.

[0067] The drive unit 5 is located below the crushing chamber 11, the second output shaft 52 extends vertically, the first gear 53 is a bevel gear, and the transmission structure includes a first transmission rod 54, a second gear 55, a first pulley 56, a second transmission rod 57, a second pulley 58, and a third gear 59.

[0068] Both the first transmission rod 54 and the second transmission rod 57 are arranged laterally, with the second transmission rod 57 located above the first transmission rod 54. The second gear 55 is a bevel gear, located at one end of the first transmission rod 54 and meshing with the first gear 53. The first pulley 56 is located at the other end of the first transmission rod 54, and the second pulley 58 is located above the first pulley 56. The second pulley 58 is located at one end of the second transmission rod 57, and the first pulley 56 and the second pulley 58 are connected by a belt 50. The third gear 59 is located at the other end of the second transmission rod 57, and the third gear 59 is a bevel gear that meshes with the teeth. The housing 1 has a through hole 14 for the third gear 59 to partially extend into.

[0069] When the drive unit 5 is working, the second output shaft 52 rotates, which drives the first gear 53 to rotate, and then drives the second gear 55, the first transmission rod 54 and the first pulley 56 to rotate. Then, through the transmission of the belt 50, the second pulley 58 is driven to rotate, which in turn causes the second transmission rod 57 and the third gear 59 to rotate. Because the third gear 59 meshes with the teeth, it will drive the cover 3 to rotate around its axis.

[0070] like Figure 5 , 6 As shown, the cover 3 has a ring of positioning plates extending circumferentially, and a ring of receiving cavities 15 is provided on the side wall of the housing 1 along its circumferential direction. The positioning plates are placed in the receiving cavities 15 and can slide along the circumferential direction of the receiving cavities 15. There are at least two positioning plates arranged vertically at intervals, and correspondingly, there are at least two receiving cavities 15 arranged vertically at intervals. In this way, the housing 1 provides multiple positioning for the cover 3, further reducing the probability of the cover 3 tilting when rotating.

[0071] A first bearing 61 is provided between the top wall of the accommodating cavity 15 and the upper surface of the positioning plate, and a second bearing 62 is provided between the bottom wall of the accommodating cavity 15 and the lower surface of the positioning plate. The bearings reduce the friction between the cover 3 and the housing 1, resulting in low rotational resistance of the cover 3. Additionally, a first gasket 63 is provided between the top wall of the accommodating cavity 15 and the first bearing 61, and a second gasket 64 is provided between the bottom wall of the accommodating cavity 15 and the second bearing 62. Because the cover 3 is frequently impacted by kitchen waste during operation, the bearings are fixed to the gaskets, which helps to reduce overall vibration and noise. Both the first gasket 63 and the second gasket 64 are made of rubber.

[0072] In this embodiment, there are two positioning plates. The upper positioning plate is called the top plate 36, which is located around the opening 31 of the cover 3. The lower positioning plate is called the annular plate 35. The annular plate 35 is provided on the outer peripheral wall of the cover 3 and is driven and connected to the driving mechanism. That is, the annular plate 35 has the aforementioned teeth on its peripheral wall.

[0073] like Figure 5 , 7 As shown in Figure 8, a feed tube 7 that can rotate around its axis is inserted into the feed inlet 12. A plug 71 is provided at the bottom of the feed tube 7, and a slot 30 is provided on the cover 3 for the plug 71 to be inserted into. The top of the slot 30 is open, so that the feed tube 7 and the cover 3 are relatively fixed in the circumferential direction. In this way, when the cover 3 rotates, it can drive the feed tube 7 to rotate synchronously, eliminating the need for a separate mechanism to drive the feed tube 7 to rotate, thus simplifying the structure.

[0074] The feed pipe 7 is equipped with a guiding structure that conveys material from top to bottom when it rotates. The guiding structure includes at least two blades 72 spaced apart circumferentially along the feed pipe 7. Each blade 72 extends along the axis of the feed pipe 7 and has an inner side 721 near the center line of the feed pipe 7 and an outer side 722 away from the center line of the feed pipe 7. Both the inner side 721 and the outer side 722 extend circumferentially along the feed pipe 7. When the feed pipe 7 rotates, the blades 72 act as guides, conveying the waste downwards.

[0075] A movable ring 73 that can move up and down relative to the feed pipe 7 is inserted in the feed pipe 7, and the movable ring 73 is fixed relative to the feed pipe 7 in the circumferential direction. The circumferential fixation between the two can adopt an existing mechanism, such as setting a vertically extending strip groove on the inner wall of the feed pipe 7, and setting an insert that can be embedded in the strip groove on the outer peripheral wall of the movable ring 73. The insert can move up and down along the strip groove.

[0076] The upper end of the outer edge 722 of each blade 72 is fixed relative to the feed pipe 7, and the lower end of the outer edge 722 of each blade 72 is connected to the movable ring 73. The movable ring 73 can move downward to a first position and upward to a second position relative to the feed pipe 7 under the action of the drive assembly. When the movable ring 73 is in the first position, the adjacent two blades 72 are staggered to form a feed inlet for the waste to pass through. When the movable ring 73 is in the second position, all the blades 72 are closed to form a structure that laterally blocks the upper end of the feed pipe 7 and separates it from the crushing chamber 11.

[0077] The blade 72 is a flexible part that can deform under external force and can be made of rubber. This allows material to be fed even when the movable ring 73 is in the second position. Although the blade 72 closes and blocks the feed pipe 7, the blade 72 can be pushed open to allow the waste to pass through by tools such as a tamping rod.

[0078] like Figure 5 , 9 As shown, the drive assembly includes a first magnetic element 81, a second magnetic element 82, and a drive structure. The first magnetic element 81 is embedded in the movable ring 73, and the second magnetic element 82 is disposed on the housing 1 and located outside the crushing chamber 11. The second magnetic element 82 can move up and down relative to the housing 1.

[0079] The drive structure is mounted on the housing 1 and located outside the crushing chamber 11. The drive structure is used to drive the second magnetic component 82 to move up and down. The drive structure includes a motor 83, a rotating shaft 84 connected to the motor 83, and a traction rope 85 wound on the rotating shaft 84. The rotating shaft 84 extends laterally, and one end of the traction rope 85 is connected to the second magnetic component 82.

[0080] When the motor 83 is working, it drives the rotating shaft 84 to rotate. The traction rope 85 drives the second magnetic component 82 to move upward. The second magnetic component 82 can move downward under the action of gravity. Because the first magnetic component 81 and the second magnetic component 82 are attracted by magnetism, the first magnetic component 81 can be driven to move up and down, so that the movable ring 73 moves synchronously.

[0081] In addition, the food waste disposer B also includes a controller, a noise detector, and a sensor that can detect the power of the drive mechanism. The noise detector and the sensor are electrically connected to the input terminal of the controller, and the drive assembly is electrically connected to the output terminal of the controller. The noise detector is located in the grinding chamber 11 or can be located outside the grinding chamber 11.

[0082] When the noise detector detects a noise level greater than or equal to the threshold, the drive assembly drives the movable ring 73 to move to the second position. At this time, the blade 72 can be manually opened to a certain extent to allow material to be fed in. When the noise detector detects a noise level less than the threshold and the sensor detects that the power difference of the drive mechanism per unit time is less than the threshold, the drive assembly drives the movable ring 73 to move to the second position. At this time, no more waste enters the crushing chamber 11, the slag guiding is basically finished, and the main task is to grind the waste. The blade 72 blocks the feed pipe 7, which can reduce external noise.

[0083] like Figure 2 , 8 As shown, the bottom of the water tank A is provided with a drain outlet A1, which is connected to the feed inlet 12 of the shell 1. The bottom of the water tank A is provided with a slag sweeping component 9 for sweeping garbage into the drain outlet A1. The slag sweeping component 9 includes an annular body 91 and slag sweeping strips 92. The annular body 91 surrounds the outer periphery of the drain outlet A1 and can rotate around its axis. Multiple slag sweeping strips 92 are spaced apart along the circumference of the annular body 91. One end of each slag sweeping strip 92 is connected to the annular body 91, and the other end extends spirally toward the center line of the annular body 91. The other end of the slag sweeping strip 92 is connected to the feed pipe 7. When the feed pipe 7 rotates, it can drive the annular body 91 to rotate, and the slag sweeping strips 92 will sweep the garbage in the water tank A toward the drain outlet A1, preventing the garbage from accumulating in the water tank A.

[0084] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
