Description

Technical Field

[0001] The present invention relates to the technical field of food waste treatment, and in particular to a food waste disposer and kitchen equipment using the same. Background Art

[0002] Kitchen waste is mostly organic matter, which is easy to breed bacteria, produce unpleasant odors, and has complex components and is difficult to sort. It is the main object of treatment in household garbage. With the implementation of garbage classification policies in various places, the sales of classified garbage bins and garbage disposers have greatly increased, and kitchen waste disposers have been purchased and used by more and more users. There are various types of existing kitchen waste disposers. Among them, the direct-discharge type garbage disposer directly discharges the garbage into the sewer by crushing it, which brings certain convenience to users. The direct-discharge type garbage disposer is generally composed of a crushing chamber, a stainless steel grinding hammer, a stainless steel grinding disc, etc. It uses a high-speed rotating permanent magnet motor to drive the grinding disc in the grinding chamber. The food waste collides with each other under the action of centrifugal force, and is ground into fine particles in a very short time and discharged into the pipe along the water flow, thereby achieving the effects of cleaning the environment and eliminating odors, providing great convenience for people's lives.

[0003] For example, the "Garbage Disposer" disclosed in the Chinese Utility Model Patent No. CN202223546707.1 (Announcement No. CN219240733U) comprises: a casing, a crushing chamber is provided in the casing, and the crushing chamber is provided with a garbage inlet and a sewage outlet; a crushing member, the crushing member is rotatably arranged in the crushing chamber; a driving assembly, the driving assembly is connected to the crushing member to drive the crushing member to rotate; an ozone generating assembly, the ozone generating assembly is used to discharge ozone into the crushing chamber; a blocking assembly, the blocking assembly is used to open or close the garbage inlet and / or the blocking assembly is used to open or close the sewage outlet, the garbage disposer is provided with a sterilization mode, in which the garbage inlet and / or the sewage outlet are closed, and the ozone generating assembly operates to pass ozone into the crushing chamber.

[0004] However, the above patent has the following problems: 1. When feeding the garbage into the crushing chamber from the garbage entrance, because the kitchen waste usually has a certain humidity, it is easy to accumulate at the garbage entrance and is not easy to be put into the crushing chamber; 2. The garbage disposer mainly relies on the rotation of the crushing parts to impact the kitchen waste for crushing. During the rapid rotation of the crushing parts, the kitchen waste will collide back and forth between the crushing parts and the wall of the crushing chamber, and the crushed garbage will splash in all directions. Although a first blocking part is provided at the garbage entrance, the first blocking part will also cause certain difficulties in feeding. The user either needs to take out the first blocking part from the garbage entrance for feeding, or even if the first blocking part of the patent is elastic, the user needs to poke the kitchen waste downward with his hand or a feeding rod to help feed, which is more troublesome; 3. Relying solely on the rotation of the crushing parts to drive the garbage to impact, the garbage crushing effect is poor and the crushing efficiency is low. Summary of the invention

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

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

[0007] The third technical problem to be solved by the present invention is to provide a food waste disposer that can close or open a feeding port according to demand in view of the current status of the prior art.

[0008] The fourth technical problem to be solved by the present invention is to provide a kitchen device using the above-mentioned food waste disposer in view of the current status of the prior art.

[0009] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a kitchen waste disposer, comprising

[0010] A shell, wherein a crushing chamber is provided inside the shell, and a feed port and a discharge port connected to the crushing chamber are provided on the shell;

[0011] A grinding assembly, comprising a grinding disc disposed transversely in the pulverizing chamber, the grinding disc being rotatable about its axis;

[0012] It is characterized by that it also includes

[0013] The cover body is arranged in the pulverizing chamber, and the cover body covers the grinding disc from top to bottom. The top of the cover body has an opening corresponding to the feed port, and there is a gap between the inner wall surface of the cover body and the peripheral edge of the grinding disc. The cover body can rotate around its axis.

[0014] In order to drive the cover to rotate, the food waste disposer also includes a driving mechanism connected to the cover, the driving mechanism includes a driving member and a second output shaft connected to the driving member, and the second output shaft is connected to the cover through a transmission assembly. The second output shaft can be directly connected to the cover, but the length of the second output shaft needs to be longer, so the second output shaft is connected to the cover through a transmission assembly.

[0015] The transmission assembly can have a variety of structural forms, and the structure is simple. A first gear is installed on the second output shaft. A circle of annular plates is formed on the outer peripheral wall of the cover body and extends laterally outward. A circle of teeth is provided on the peripheral wall of the annular plate. The first gear and the teeth are meshed through a transmission structure. The first gear, the teeth and the transmission structure together constitute the transmission assembly.

[0016] The driving member is arranged below the pulverizing chamber, the second output shaft extends vertically, the first gear is a bevel gear, and the transmission structure can be a plurality of gears meshing with each other, but the number of gears involved is relatively large, so the transmission structure includes

[0017] A first transmission rod, arranged transversely;

[0018] The second gear is a bevel gear, which is disposed at one end of the first transmission rod and meshes with the first gear;

[0019] A first pulley, disposed at the other end of the first transmission rod;

[0020] A second transmission rod, arranged transversely and located above the first transmission rod;

[0021] A second pulley is located 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 by belt transmission;

[0022] The third gear is arranged at the other end of the second transmission rod, the third gear is a bevel gear and meshes with the tooth portion, and the housing is provided with a through hole for the third gear to partially extend into. By means of belt transmission, fewer components are used, and long-distance transmission of the first gear and the tooth portion can be achieved.

[0023] In order to reduce the number of components involved, the driving mechanism further includes a first output shaft drivingly connected to the driving member, and the first output shaft extends into the crushing chamber and is drivingly connected to the grinding disc. In this way, the driving member is provided with double output shafts, which can realize the rotation of the cover body and the grinding disc, and there is no need to provide a driving member for both the cover body and the grinding disc.

[0024] In order to ensure the smooth rotation of the cover body, the cover body has a circle of positioning plates extending along its circumference, and a circle of accommodating cavities are provided on the side walls of the shell along its circumference. The positioning plates are placed in the accommodating cavities and can slide along the circumference of the accommodating cavities. The shell plays a certain positioning role on the cover body, so that the cover body rotates smoothly.

[0025] In order to make the cover body rotate smoothly, a first bearing is provided between the top wall surface of the accommodating cavity and the upper surface of the positioning plate, and a second bearing is provided 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 body and the shell, so that the rotation resistance of the cover body is small.

[0026] In order to reduce the vibration caused by the rotation of the cover, a first gasket is provided between the top wall of the accommodating cavity and the first bearing, and a second gasket is provided between the bottom wall of the accommodating cavity and the second bearing. Because the cover will be frequently hit by kitchen waste during operation, the bearing is fixed on the gasket to achieve overall shock absorption and noise reduction. The first gasket and the second gasket are both made of rubber.

[0027] In order to further ensure the stable rotation of the cover, the positioning plates are provided with at least two spaced apart from each other, and correspondingly, the accommodating chambers are provided with at least two spaced apart from each other. In this way, the housing can position the cover at multiple locations, further reducing the probability of tilting of the cover when rotating.

[0028] In the above scheme, there are two positioning plates. The upper positioning plate is called the top plate, which is located at the periphery of the opening of the cover body; the lower positioning plate is called the annular plate, which is arranged on the outer peripheral wall of the cover body and is connected to the driving mechanism.

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

[0030] In order to further improve the grinding efficiency of the garbage, the cover body is provided with at least two shearing openings spaced along the circumference thereof, and the shearing openings are arranged around the outer circumference of the grinding disc. The shearing openings can also play a shearing role on the garbage, and after the garbage is sheared, it flows from the gap between the cover body and the outer circumference of the grinding disc to the lower part of the crushing chamber.

[0031] The technical solution adopted by the present invention to solve the above second technical problem is: a feed pipe that can rotate around its axis is inserted in the feed port, and the feed pipe is provided with a material guiding structure that can transport materials from top to bottom when it rotates.

[0032] The material guide structure can have a variety of structural forms, such as blades that are integrally spirally arranged in the feed pipe along the axial direction of the feed pipe, or the material guide structure includes at least two blades that are spaced apart along the circumference of the feed pipe, each of which extends along the axis of the feed pipe, and each of which has an inner side edge close to the center line of the feed pipe and an outer side edge away from the center line of the feed pipe, and both the inner side edge and the outer side edge extend along the circumference of the feed pipe. When the feed pipe rotates, the blades play a guiding role to transport the garbage downward.

[0033] The technical solution adopted by the present invention to solve the third technical problem is: a movable ring capable of moving up and down relative to the feed pipe is inserted in the feed pipe, and the movable ring is fixed relative to the feed pipe in the circumferential direction, the upper end of the outer side edge of each blade is fixed relative to the feed pipe, and the lower end of the outer side edge 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 feed pipe under the action of the driving assembly. When the movable ring is in the first position, two adjacent blades are staggered to form a feeding port for garbage to pass through. When the movable ring is in the second position, all the blades are closed to form a structure that horizontally blocks the feed pipe and separates the upper end of the feed pipe from the crushing chamber.

[0035] In order to enable feeding when the movable ring is in the second position, the blades are flexible parts that can be deformed under the action of external force. At this time, although the blades are closed to block the feed pipe, the blades can be poked out of the opening by tools such as tamping rods to allow garbage to pass through.

[0036] The drive assembly can have a variety of structural forms, such as an electric push rod directly pushing the movable ring, but in this case, at least part of the electric push rod needs to be set in the crushing chamber, which not only occupies the space of the crushing chamber, but is also easily contaminated by garbage. Therefore, the drive assembly includes

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

[0038] A second magnetic member is arranged on the shell and located outside the pulverizing chamber, the second magnetic member can move up and down relative to the shell, and the second magnetic member and the first magnetic member are magnetically attracted to each other;

[0039] The driving structure is arranged on the shell and outside the crushing chamber, and is used to drive the second magnetic member to move up and down. In this way, only the first magnetic member is arranged in the crushing chamber, the second magnetic member and the driving structure are arranged outside the crushing chamber, and the first magnetic member is embedded in the movable ring, which does not occupy additional space in the crushing chamber.

[0040] The driving structure may be an electric push rod, or may be, the driving structure includes a motor, a rotating shaft connected to the motor drive, and a traction rope wound around the rotating shaft, the rotating shaft extends laterally, and one end of the traction rope is connected to the second magnetic member.

[0041] A driving mechanism can be provided to drive the feed pipe to rotate, and preferably, the feed pipe and the cover body are relatively fixed in the circumferential direction. In this way, when the cover body rotates, the feed pipe can be driven to rotate synchronously, and there is no need to provide a mechanism to drive the feed pipe to rotate, which simplifies the structure.

[0042] In order to automatically control the movable ring to be in the first position or the second position, the food waste disposer further includes a controller, a noise detector, and a sensor capable of detecting the power of the driving mechanism, wherein the noise detector and the sensor are both electrically connected to the input end of the controller, the driving assembly is electrically connected to the output end of the controller, and the noise detector is arranged on the housing;

[0043] When the noise detector detects that the noise decibel value is greater than or equal to the threshold, the drive component drives the movable ring to move to the second position. At this time, the blade can be manually poked open to a certain opening for feeding; when the noise detector detects that the noise decibel value is less than the threshold and the sensor detects that the power difference of the driving mechanism per unit time is less than the threshold, the drive component drives the movable ring to move to the second position. At this time, there is no more garbage entering the crushing chamber, and the slag guiding is basically completed, mainly for the grinding of garbage. The blades block the feed pipe, which can reduce 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 arranged below the sink, and a drain outlet is provided at the bottom of the sink, and the drain outlet is connected to the feed port of the shell.

[0045] 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 arranged below the sink, and a drain outlet is provided at the bottom of the sink, and the drain outlet is connected to the feed port of the shell.

[0046] Preferably, a slag sweeping piece for sweeping garbage into the drain outlet is provided at the bottom of the water tank, so that the garbage in the water tank can be pushed into the drain outlet without manual operation.

[0047] The slag sweeping member can have a variety of structural forms, such as a push plate that can move toward or away from the drain outlet. Preferably, the slag sweeping member includes an annular body and a slag sweeping bar. The annular body surrounds the outer periphery of the drain outlet and can rotate around its axis. The annular body is provided with a plurality of slag sweeping bars at intervals along its circumference. One end of each slag sweeping bar is connected to the annular body, and the other end spirally extends toward the center line of the annular body. In this way, when the annular body rotates, the slag sweeping bar will sweep the garbage in the sink toward the drain outlet to prevent the garbage from accumulating in the sink.

[0048] In order to make the annular body rotate, the other end of the slag sweeping bar is connected to the feed pipe, so that when the feed pipe rotates, the annular body can be driven to rotate, and there is no need to set up a separate structure for driving the annular body to rotate, and the structure is relatively simple.

[0049] Compared with the prior art, the advantages of the present invention are as follows: 1. The cover body of the present invention can rotate around its axis, and the grinding disc can also rotate around its axis. Compared with the method in which only the grinding disc rotates, the relative movement of the grinding disc and the cover body can be increased, thereby enhancing the impact force and friction force on the kitchen waste and improving the grinding effect; 2. The present invention inserts a rotatable feed pipe into the feed pipe, and a material guide structure is provided in the feed pipe. When feeding, the feed pipe rotates, and the material guide structure can transport the garbage from top to bottom to the crushing chamber to prevent the garbage from accumulating at the feed inlet; 3. The blades of the material guide structure of the present invention The upper end of the outer side is fixed relative to the feed pipe, and 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 two adjacent blades are staggered to form a feeding port for garbage to pass through, so that feeding can be carried out normally. When feeding is not needed, the movable ring moves upward to the second position, and all the blades are closed to form a structure shielding the feed pipe. On the one hand, it can prevent the impacted garbage from splashing out of the feed port, playing the role of a splashproof cover. On the other hand, it can also isolate part of the noise generated when the food waste disposer is working in the crushing chamber, reducing the noise impact on the user.

[0061] The present invention is further described in detail below with reference to the accompanying drawings.

[0062] like Figures 1 to 11 As shown, the kitchen equipment of this preferred embodiment includes a sink A and a food waste disposer B, and the food waste disposer B is arranged below the sink A.

[0063] like Figures 3 to 6 As shown, the food waste disposer B includes a housing 1, a grinding assembly, a cover 3 and a driving mechanism. The housing 1 has a grinding chamber 11 inside, and is provided with a feed port 12 and a discharge port 13 connected to the grinding chamber 11. The feed port 12 is located at the top of the housing 1, and the discharge port 13 is provided on the side wall of the housing 1.

[0064] The grinding assembly includes a grinding disc 2 which is transversely arranged in the pulverizing chamber 11. The grinding disc 2 can rotate around its axis. The grinding assembly can adopt an existing structure.

[0065] The cover body 3 is arranged in the crushing chamber 11, and the cover body 3 can rotate around its axis. The cover body 3 covers the grinding disc 2 from top to bottom. The top of the cover body 3 has an opening 31 corresponding to the feed port 12, and there is a gap 32 between the inner wall surface of the cover body 3 and the peripheral edge of the grinding disc 2. The cover body 3 is provided with at least two shearing openings 33 arranged at intervals along its circumference, and the shearing openings 33 are arranged around the outer peripheral edge of the grinding disc 2. The shearing openings 33 can also play a shearing role on the garbage. After the garbage is sheared, it flows from the gap 32 between the cover body 3 and the outer peripheral edge of the grinding disc 2 to the lower part of the crushing chamber 11. A grinding block 34 is provided on the inner wall surface of the cover body 3. During the rotation of the cover body 3, the grinding block 34 can also cut the garbage.

[0066] The driving mechanism can drive the cover 3 to rotate, and can also drive the grinding disc 2 to rotate. Figure 4 , 6 As shown in Figures 1 and 9, the driving mechanism includes a driving member 5 and a first output shaft 51 and a second output shaft 52 drivingly connected to the driving member 5. The first output shaft 51 extends into the pulverizing chamber 11 and is drivingly connected to the grinding disc 2, and the second output shaft 52 is drivingly connected to the cover body 3 through a transmission assembly. In this way, a double output shaft is provided on the driving member 5, so that the rotation of the cover body 3 and the grinding disc 2 can be realized, and there is no need to provide a driving member 5 for both the cover body 3 and the grinding disc 2.

[0067] A first gear 53 is mounted on the second output shaft 52. A ring plate 35 is formed on the outer peripheral wall of the cover body 3 and extends laterally outward. 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 are meshed with each other through a transmission structure. The first gear 53, the teeth and the transmission structure together constitute a transmission assembly.

[0068] The driving member 5 is arranged 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 .

[0069] The first transmission rod 54 and the second transmission rod 57 are both arranged transversely, and the second transmission rod 57 is located above the first transmission rod 54. The second gear 55 is a bevel gear, which is arranged at one end of the first transmission rod 54 and meshes with the first gear 53. The first pulley 56 is arranged 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 arranged at one end of the second transmission rod 57. The first pulley 56 and the second pulley 58 are connected by a belt 50. The third gear 59 is arranged at the other end of the second transmission rod 57. The third gear 59 is a bevel gear and meshes with the tooth portion. The housing 1 is provided with a through hole 14 for the third gear 59 to partially extend into.

[0070] When the driving member 5 works, the second output shaft 52 rotates, driving the first gear 53 to rotate, and then driving the second gear 55, the first transmission rod 54 and the first pulley 56 to rotate, and then the second pulley 58 is driven to rotate through the transmission of the belt 50, and then the second transmission rod 57 and the third gear 59 are rotated. Because the third gear 59 is meshed with the tooth portion, it will drive the cover body 3 to rotate around its axis.

[0071] like Figure 5 , 6 As shown, the cover body 3 has a circle of positioning plates extending along its circumference, and a circle of accommodating cavities 15 are provided on the side wall of the housing 1 along its circumference. The positioning plates are placed in the accommodating cavities 15 and can slide along the circumference of the accommodating cavities 15. There are at least two positioning plates arranged at intervals up and down, and correspondingly, there are at least two accommodating cavities 15 arranged at intervals up and down. In this way, the housing 1 positions the cover body 3 at multiple locations, further reducing the probability of the cover body 3 tilting when rotating.

[0072] A first bearing 61 is provided between the top wall surface of the accommodating chamber 15 and the upper surface of the positioning plate, and a second bearing 62 is provided between the bottom wall surface of the accommodating chamber 15 and the lower surface of the positioning plate. The setting of the bearing reduces the friction between the cover body 3 and the shell 1, so that the rotation resistance of the cover body 3 is small. In addition, a first gasket 63 is provided between the top wall surface of the accommodating chamber 15 and the first bearing 61, and a second gasket 64 is provided between the bottom wall surface of the accommodating chamber 15 and the second bearing 62. Because the cover body 3 will be frequently hit by kitchen waste during operation, the bearing is fixed on the gasket, which can play a role in overall shock absorption and noise reduction. The first gasket 63 and the second gasket 64 are both made of rubber.

[0073] In this embodiment, there are two positioning plates. The upper positioning plate is called the top plate 36, which is located on the periphery of the opening 31 of the cover body 3; the lower positioning plate is called the annular plate 35, which is arranged on the outer peripheral wall of the cover body 3 and is connected to the driving mechanism, that is, the peripheral wall of the annular plate 35 is provided with the above-mentioned teeth.

[0074] like Figure 5 , 7 As shown in Figures 8 and 9, a feed pipe 7 that can rotate around its axis is inserted in the feed port 12, an insert block 71 is provided at the bottom of the feed pipe 7, and a slot 30 that can be inserted into the insert block 71 is provided on the cover body 3, and the top of the slot 30 is open, so that the feed pipe 7 and the cover body 3 are relatively fixed in the circumferential direction. In this way, when the cover body 3 rotates, the feed pipe 7 can be driven to rotate synchronously, and there is no need to set a mechanism for driving the feed pipe 7 to rotate, and the structure is simplified.

[0075] The feed pipe 7 is provided with a material guide structure that can transport materials from top to bottom when the feed pipe 7 rotates. The material guide structure includes at least two blades 72 arranged at intervals along the circumference of the feed pipe 7. Each blade 72 extends along the axis of the feed pipe 7, and each blade 72 has an inner side edge 721 close to the center line of the feed pipe 7 and an outer side edge 722 away from the center line of the feed pipe 7. The inner side edge 721 and the outer side edge 722 both extend along the circumference of the feed pipe 7. When the feed pipe 7 rotates, the blades 72 play a guiding role to transport the garbage downward.

[0076] A movable ring 73 capable of moving 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 providing a vertically extending strip groove on the inner wall surface of the feed pipe 7, and providing an insert on the outer circumferential wall of the movable ring 73 that can be embedded in the strip groove, and the insert can move up and down along the strip groove.

[0077] The upper end of the outer side edge 722 of each blade 72 is fixed relative to the feed pipe 7, and the lower end of the outer side 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 driving assembly. When the movable ring 73 is in the first position, two adjacent blades 72 are staggered to form a feeding port for garbage to pass through. When the movable ring 73 is in the second position, all the blades 72 are closed to form a structure that horizontally blocks the feed pipe 7 and separates the upper end of the feed pipe 7 from the crushing chamber 11.

[0078] The blade 72 is a flexible part that can be deformed under the action of external force and can be made of rubber. In this way, when the movable ring 73 is in the second position, material can still be fed. At this time, although the blade 72 is closed to block the feed pipe 7, the blade 72 can be poked out of the opening 31 by a tool such as a pounding rod to allow garbage to pass through.

[0079] like Figure 5 , 9 As shown, the driving assembly includes a first magnetic member 81, a second magnetic member 82 and a driving structure. The first magnetic member 81 is embedded in the movable ring 73, and the second magnetic member 82 is arranged on the shell 1 and located outside the crushing chamber 11. The second magnetic member 82 can move up and down relative to the shell 1.

[0080] The driving structure is disposed on the housing 1 and outside the pulverizing chamber 11, and is used to drive the second magnetic member 82 to move up and down. The driving structure includes a motor 83, a rotating shaft 84 connected to the motor 83, and a traction rope 85 wound around the rotating shaft 84, the rotating shaft 84 extends horizontally, and one end of the traction rope 85 is connected to the second magnetic member 82.

[0081] When the motor 83 is working, it drives the rotating shaft 84 to rotate, and 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 magnetically attracted to each other, the first magnetic component 81 can be driven to move up and down, so that the movable ring 73 moves synchronously.

[0082] In addition, the food waste disposer B also includes a controller, a noise detector and a sensor that can detect the power of the driving mechanism. The noise detector and the sensor are electrically connected to the input end of the controller, and the driving component is electrically connected to the output end of the controller. The noise detector is arranged in the crushing chamber 11 and can also be arranged outside the crushing chamber 11.

[0083] When the noise detector detects that the noise decibel value is greater than or equal to the threshold value, the drive component drives the movable ring 73 to move to the second position. At this time, the blade 72 can be manually poked to a certain opening 31 for feeding; when the noise detector detects that the noise decibel value is less than the threshold value, and the sensor detects that the power difference of the driving mechanism per unit time is less than the threshold value, the drive component drives the movable ring 73 to move to the second position. At this time, there is no more garbage entering the crushing chamber 11, and the slag guiding is basically completed, mainly for the grinding of garbage. The blade 72 blocks the feed pipe 7, which can reduce external noise.

[0084] like Figure 2 , 8 As shown, a drain port A1 is provided at the bottom of the water tank A, and the drain port A1 is communicated with the feed port 12 of the shell 1.
