Description

Technical Field

[0001] The invention belongs to the field of garbage disposal, and in particular relates to a garbage disposer for processing kitchen garbage. Background Art

[0002] A kitchen food waste disposer is a kitchen appliance that is installed under the kitchen sink and connected to the drain pipe. The blade is driven by an AC or DC motor, and the food waste in the crushing chamber is crushed by centrifugal force and then discharged into the sewer. It can easily achieve instant, convenient and fast kitchen cleaning, avoid the breeding of bacteria, mosquitoes and odors due to the storage of food waste, and thus create a healthy, clean and beautiful kitchen environment.

[0003] Traditional food waste disposers include a feeding area, a crushing area, and a power area that drives the crushing area. The garbage entering from the feeding area is crushed into small enough particles in the crushing area and then directly discharged into the sewer pipe. For example, the Chinese invention patent "A method for treating kitchen waste" with patent number ZL201610836231.5 (authorization announcement number CN106631194B) discloses that the garbage disposal tool includes an outer barrel, a barrel, a guide pipe, a heating block, a control module, a reduction motor, a transmission mechanism, a fixed blade, a moving blade, and a rotating shaft. After the kitchen waste enters the cavity of the barrel, it is heated and dried, and is mixed, cut, and squeezed to crush the waste. When the waste is fibrous waste, the waste is relatively tough and soft, and will pile up fluffy after drying. In the above patent, the waste in the gap between the moving blade (first cutting piece) and the fixed blade is cut. When the waste is high-fiber kitchen waste such as leeks, corn, animal hair, corn silk, celery, and edamame skin, it is easy to be entangled on the moving blade (cutting piece) and easily piled up in the gap and cannot be processed, thereby affecting the rotation of the moving blade.

[0004] Therefore, it is necessary to further improve the existing garbage disposer. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a garbage disposer which reduces garbage entanglement and improves the crushing capacity in view of the current status of the above-mentioned prior art.

[0006] The second technical problem to be solved by the present invention is to provide a garbage disposer for cleaning the inner wall of the cavity.

[0007] The third technical problem to be solved by the present invention is to provide a garbage disposer which reduces the adhesion of garbage to the inner wall of the cavity.

[0008] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a garbage disposer includes a shell, the interior of which is hollow to form a cavity, and has a feed port connected to the cavity;

[0009] a rotating shaft, rotatably disposed on the housing and at least partially located in the cavity;

[0010] A first cutting member is located on the peripheral side of the rotating shaft, extends laterally, and rotates together with the rotating shaft;

[0011] It is characterized by also including:

[0012] a second cutting member, disposed on the outer peripheral wall of the first cutting member;

[0013] The first driving mechanism has a power output end drivingly connected to the second cutting member, thereby driving the second cutting member to move along the length direction or circumferential direction of the first cutting member.

[0014] In order to improve the cutting efficiency, a fixed knife is arranged in the cavity, and a gap is left between the fixed knife and the first cutting member. When the first cutting member rotates to a position corresponding to the fixed knife, the second cutting member is at least partially located in the gap. In this way, the second cutting member can crush and cut the garbage accumulated in the gap during the movement, reducing the possibility of garbage accumulation in the gap.

[0015] There are many structural forms of the second cutting member, which can be in the form of an annular conveyor belt or a strip. However, from the perspective of cutting efficiency, preferably, the second cutting member is a conveyor belt that at least partially surrounds the periphery of the first cutting member, the conveyor belt is annular and extends along the length direction of the first cutting member, and the outer peripheral wall of the conveyor belt is provided with cutting teeth for cutting. Since the conveyor belt surrounds the outer wall surface of the first cutting member in the length direction, on the one hand, during the movement of the conveyor belt, the garbage on the entire first cutting member can be cut to prevent high-fiber garbage from being entangled on the first cutting member, reducing the dead angle of entanglement, and on the other hand, it also reduces the accumulation and entanglement of garbage in the entire gap.

[0016] The first driving mechanism has various structural forms, such as gear transmission or roller transmission. However, from the perspective of transmission reliability, preferably, the first driving mechanism includes:

[0017] a first motor, disposed in the first cutting member;

[0018] A gear is mounted on the power output shaft of the first motor and is located inside the conveyor belt; a plurality of inner teeth arranged at intervals along the circumference of the conveyor belt are provided on the inner circumferential wall of the conveyor belt, and the gear is meshed with the inner teeth.

[0019] Preferably, a mounting shaft is provided on the rotating shaft, and the first cutting member is a first cutting knife which is provided on the outer peripheral wall of the mounting shaft and extends laterally.

[0020] In order to improve the grinding and crushing efficiency, at least one second cutting knife is arranged on the outer peripheral wall of the mounting shaft, and the second cutting knife is arranged with an interval with the first cutting knife along the circumferential direction.

[0021] In order to burn off the garbage entangled on the first cutting blade and the second cutting blade, the first cutting blade and the second cutting blade are both provided with a heating element. Thus, the presence of the heating element can burn off and carbonize the garbage entangled on the corresponding cutting blade, thereby reducing the accumulation of garbage on the first cutting blade and the second cutting blade.

[0022] The rotating shaft may be arranged vertically or horizontally, but preferably, the rotating shaft is arranged vertically and mounted on the bottom wall of the housing.

[0023] In order to improve the drying efficiency, the second cutting blade is hollow inside to form a chamber, and an outlet connected to the chamber is provided on the top wall of the second cutting blade, and an air inlet channel is provided on the wall plate of the chamber, and the air inlet channel is located upstream of the outlet along the fluid flow path. In this way, fresh air from the outside flows out through the outlet on the second cutting blade, and a spiral upward airflow is formed during the rotation of the second cutting blade, thereby strengthening the heat convection in the cavity and improving the drying efficiency.

[0024] In order to improve heat convection, there are multiple outlets, which are arranged at intervals along the length direction of the second cutting knife.

[0025] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: a water inlet channel is opened on the second cutting knife for connecting with the liquid supply component inside the garbage disposer, and the water inlet channel is connected with the chamber and is not connected with the air inlet channel.

[0026] In order to discharge the fluid in the cavity, the fixed knife is arranged on the inner wall of the cavity and extends inwardly. The interior of the fixed knife is hollow to form a cavity. An inlet connected to the cavity is opened on the bottom wall of the fixed knife. The cavity is provided with an outlet for connecting to a fan. The fan is located outside the cavity.

[0027] In order to achieve the purpose of deodorization, a deodorization device is also included, the air inlet end of the deodorization device is connected to the exhaust port of the cavity, and the air outlet end of the deodorization device is connected to the air inlet of the fan.

[0028] Preferably, when the second cutting knife rotates to the corresponding position of the fixed knife, the second cutting knife is located below the fixed knife, and when the first cutting knife rotates to the position of the fixed knife, the first cutting knife is located above the fixed knife, and the gap is formed between the first cutting knife and the fixed knife. In this way, the garbage in the gap is cut after being squeezed by the fixed knife and the first cutting knife, and the garbage between the fixed knife and the second cutting knife is cut after being squeezed by the fixed knife and the second cutting knife, that is, the garbage above and below the fixed knife can be squeezed and crushed, which improves the uniformity of garbage cutting and improves the cutting efficiency.

[0029] The technical solution adopted by the present invention to solve the third technical problem is as follows: a convex portion is provided on the bottom of the second cutting knife, and cutting teeth for cutting are provided on the outer peripheral wall of the convex portion.

[0030] In order to reduce the size of the garbage after cutting, there are multiple protrusions and they are arranged at intervals along the length direction of the second cutting blade, and a cutting channel is formed between two adjacent protrusions, and along the rotation direction of the second cutting blade, the cutting channel gradually shrinks inward. In this way, the cutting channel continuously crushes the garbage and cuts the garbage into small pieces, thereby reducing the size of the garbage after cutting.

[0031] In order to dry and carbonize the garbage in the cavity, a heating plate is arranged on the bottom wall of the cavity.

[0032] The rotating shaft can be driven manually or electrically, but from the perspective of crushing efficiency and crushing effect, it is preferably also provided with a second driving mechanism for driving the rotating shaft to rotate, and the power output end of the second driving mechanism is drivingly connected to the rotating shaft.

[0033] There are many structural forms of the second drive mechanism for realizing the rotation of the shaft, which can be in the form of a combination of gears and a motor, or in the form of a gear and an annular transmission belt. However, preferably, the second drive mechanism includes

[0034] a second motor, located outside the cavity, with its output shaft extending vertically;

[0035] A driving gear, mounted on the output shaft of the second motor;

[0036] A connecting shaft is arranged side by side with the output shaft of the second motor at intervals;

[0037] A first transmission gear, mounted on the connecting shaft and meshing with the driving gear;

[0038] A driven gear is mounted on the connecting shaft and is located above the first transmission gear; and

[0039] The second transmission gear is mounted on the rotating shaft and meshes with the driven gear.

[0040] Compared with the prior art, the advantage of the present invention is that the second cutting piece in the garbage disposer is arranged on the outer peripheral wall of the first cutting piece, and moves relative to the first cutting piece under the drive of the first driving mechanism, so as to cut the garbage on the first cutting piece, prevent the garbage from being entangled on the first cutting piece and affecting the rotation of the first cutting piece, thereby preventing damage to the first driving mechanism and improving the service life of the garbage disposer.

[0051] The present invention is further described in detail below with reference to the accompanying drawings.

[0052] like Figures 1 to 10 As shown, the garbage disposer of the embodiment of the present invention includes a shell 1, a rotating shaft 2, a first cutting member, a fixed knife 4, a second cutting member, a deodorizing device 03, a first driving mechanism 6, a fan 7, a heating plate 8 and a second driving mechanism 9.

[0053] like Figure 2 As shown, the shell 1 is hollow inside to form a cavity 11, and has a feed port 111 connected to the cavity 11. Specifically, the top of the cavity 11 is open, and the top opening is the aforementioned feed port 111. The feed port 111 in this embodiment is covered with a cover plate.

[0054] like Figures 2 to 3 As shown, the rotating shaft 2 is vertically arranged and rotatably arranged on the bottom wall of the housing 1, and the rotating shaft 2 is partially located in the cavity 11. The second driving mechanism 9 is used to drive the rotating shaft 2 to rotate, and the power output end of the second driving mechanism 9 is drivingly connected to the rotating shaft 2. Specifically, as Figure 4 As shown, the second driving mechanism 9 includes a second motor 91, a driving gear 92, a connecting shaft 93, a first transmission gear 94, a driven gear 95 and a second transmission gear 96, wherein the driving gear 92 and the driven gear 95 are small gears, and the first transmission gear 94 and the second transmission gear 96 are large gears. Figure 2 and Figure 4 As shown, the second motor 91 is located outside the cavity 11, and the output shaft of the second motor 91 extends vertically; the driving gear 92 is mounted on the output shaft of the second motor 91; the connecting shaft 93 is vertically arranged and arranged side by side with the output shaft of the second motor 91; the first transmission gear 94 is mounted on the connecting shaft 93 and meshes with the driving gear 92; the driven gear 95 is mounted on the connecting shaft 93 and is located above the first transmission gear 94; the second transmission gear 96 is mounted on the rotating shaft 2 and meshes with the driven gear 95. In this way, under the drive of the second motor 91, and under the transmission of the driving gear 92, the connecting shaft 93, the first transmission gear 94, the driven gear 95 and the second transmission gear 96, the rotating shaft 2 will be driven to rotate.

[0055] The first cutting member rotates under the drive of the rotating shaft 2. The first cutting member is arranged on the rotating shaft 2 and rotates together with the rotating shaft 2. Specifically, Figure 3 As shown, the aforementioned rotating shaft 2 is provided with a mounting shaft 3, and the first cutting member is a first cutting knife 31 which is provided on the outer peripheral wall of the mounting shaft 3 and extends laterally. Figure 2 and Figure 4 As shown, the end of the first cutting blade 31 has a bent section 310 extending upward and then laterally outward. Figures 2 to 4 As shown, the fixed blade 4 is fixedly arranged on the inner wall of the cavity 11 and extends inwardly. Figure 3 and Figure 4 As shown, when the first cutting knife 31 rotates with the rotating shaft 2 to a position corresponding to the fixed knife 4, the fixed knife 4 is located below the first cutting knife 31, and a gap 01 is left between the fixed knife 4 and the first cutting knife 31.

[0056] The second cutting member is disposed on the outer peripheral wall of the first cutting blade 31, and when the first cutting blade 31 rotates to a position corresponding to the fixed blade 4, the second cutting member is at least partially located in the gap 01 to cut the garbage in the gap 01. Figure 5 and Figure 6 As shown, the outer peripheral wall of the first cutting blade 31 is provided with a groove 315 along the circumference of the length direction thereof, and the groove 315 is annular. Figure 2 and Figure 3 As shown, the second cutting member is a conveyor belt 5 that surrounds the periphery of the first cutting blade 31 and is located in the groove 315. Therefore, the conveyor belt 5 is annular and extends along the length direction of the first cutting blade 31. The inner peripheral wall of the conveyor belt 5 is provided with a plurality of inner teeth 52 arranged at intervals along the circumference thereof, and the outer peripheral wall of the conveyor belt 5 is provided with a cutting tooth portion 51 for cutting. For details, see Figure 3 and Figure 4 shown.

[0057] In order to continuously cut and crush the garbage in the gap 01, the conveyor belt 5 of the second cutting member moves along the length direction of the gap 01 under the drive of the first driving mechanism 6. Specifically, the first driving mechanism 6 includes a first motor and a gear 62, wherein the first motor (not shown) is arranged in the first cutting blade 31; Figure 3 As shown, the gear 62 is mounted on the power output shaft 611 of the first motor and is located inside the conveyor belt 5 and meshes with the inner tooth portion 52 on the inner circumferential wall of the conveyor belt 5. For details, see Figure 3 As shown. In this way, under the drive of the first motor, the conveyor belt 5 can move around the first cutting blade 31 through the meshing of its inner tooth portion 52 and the gear 62, so that the cutting tooth portion 51 of the conveyor belt 5 continuously cuts the garbage in the gap 01 and the garbage on the outer surface of the first cutting blade 31, preventing the garbage from accumulating and entangled in the gap 01 and the first cutting blade 31 and affecting the rotation of the first cutting blade 31.

[0058] like Figures 5 to 7As shown, the outer peripheral wall of the above-mentioned installation shaft 3 extends outward to form a second cutting knife 32, there are two second cutting knives 32, and they are arranged at intervals along the circumference of the installation shaft 3, and when the second cutting knife 32 rotates to the corresponding position of the second cutting knife 4, the second cutting knife 32 can be located below the fixed knife 4. In addition, the first cutting knife 31, the second cutting knife 32 and the fixed knife 4 are all provided with heating elements, and the heating elements of the first cutting knife 31, the second cutting knife 32 and the fixed knife 4 can burn off the garbage wrapped around the corresponding cutting knife, reducing the possibility of garbage entanglement and accumulation. The heating element can be in the form of a heating film or a heating wire, as long as it can achieve heating of the first cutting knife 31 and the second cutting knife 32. In addition, a heating plate 8 is provided below the cavity 11 and on the bottom wall surface of the cavity 11, and the heating plate 8 is used to heat the inside of the cavity, thereby carbonizing the garbage inside the cavity. The heating plate 8 is provided with an escape opening for the rotating shaft 2 to pass through at the position corresponding to the rotating shaft 2.

[0059] like Figure 4 and Figure 5 As shown, the free end of the second cutting knife 32 extends upward to form a longitudinal knife portion 320, and the fixed knife 4 extends upward to form a step 40 at a position corresponding to the longitudinal knife portion 320. When the second cutting knife 32 is rotated to a position corresponding to the fixed knife 4, the second cutting knife 32 can be located under the step 40, and when the first cutting knife 31 is rotated to a position corresponding to the fixed knife 4, as shown in FIG. Figure 3 As shown, the bending section 310 of the first cutting blade 31 is partially located above the step 40. Figure 6 As shown, a convex portion 323 is convexly provided at the bottom of the second cutting knife 32. Along the rotation direction of the second cutting knife 32, the convex portion 323 is a tapered structure with a gradually increasing longitudinal section, and the taper of the convex portion 323. The outer peripheral wall of the aforementioned convex portion 323 is provided with cutting teeth 3231 for cutting. There are multiple convex portions 323 and they are arranged at intervals along the length direction of the second cutting knife 32. A cutting channel 324 is formed between two adjacent convex portions 323, and along the rotation direction of the second cutting knife 32, the cutting channel 324 gradually shrinks inward. In this way, during the rotation of the second cutting knife 32, the kitchen waste at the bottom of the cavity 11 can be better cut into small pieces, the degree of refinement is improved, and the efficiency of heating and carbonization can be improved to a certain extent.

[0060] In order to prevent the garbage from sticking to the bottom of the shell when heated at high temperatures, Figure 7As shown, the second cutting blade 32 is hollow inside to form a chamber 321, and an outlet 3212 connected to the chamber 321 is provided on the top wall of the second cutting blade 32, and an air inlet channel 3111 is provided on the wall panel of the chamber 321. Along the fluid flow path, the air inlet channel 3111 is located upstream of the outlet 3212. There are multiple outlets 3212, which are arranged at intervals along the length direction of the second cutting blade 32. Due to the arrangement of the outlet 3212 on the second cutting blade 32, during the grinding and drying process, the second cutting blade 32 rotates and discharges hot air, so that the gas in the cavity forms a spiral airflow, thereby enhancing heat convection, improving the drying efficiency, and reducing the time for garbage disposal. In addition, as Fig.10 As shown, the second cutting blade 32 is provided with a water inlet channel 322 for communicating with the liquid supply assembly inside the garbage disposer. The water inlet channel 322 is connected to the chamber 321 and is not connected to the air inlet channel 3111. Fig.10 As shown, the air inlet channel 3111 is provided with an air inlet valve 3112 for controlling whether the air inlet channel 3111 is on or off, and the water inlet channel 322 is provided with a water inlet valve 3223 for controlling whether the water inlet channel 322 is on or off. Fig.10 For schematic purposes only.

[0061] Thus, during the grinding and drying process, the water inlet valve 3223 is closed, and the air inlet valve 3112 is opened. The fresh air outside the cavity 11 enters the chamber 321 through the air inlet valve 3112, is heated into hot air by the heating element on the second cutting blade 32, and is ejected through the outlet 3212. As the second cutting blade 32 rotates, a vortex is formed inside the cavity 11, accelerating the convection heat transfer in the cavity 11 and improving the drying efficiency. During cleaning, the water inlet valve 3223 is in an open state, and water enters the chamber 321 through the water inlet valve 3223, and then is ejected through the outlet to clean the inside of the cavity. After cleaning, the sterilization and drying mode is entered, at which time the water inlet valve is closed, and the outlet ejects hot air again to sterilize and disinfect the inside of the cavity 11.

[0062] like Figure 3 and Fig. 9 As shown, the interior of the fixed knife 4 is hollow to form a cavity 41, the bottom wall of the fixed knife 4 is provided with an inlet 411 connected to the cavity 41, and the cavity 41 is provided with an outlet 412. Figure 1 and Figure 2 As shown, the air inlet end of the deodorizing device 03 is connected to the exhaust port 412 of the cavity 41 through the connecting pipe 031, and the air outlet end of the deodorizing device 03 is connected to the air inlet of the fan 7. The deodorizing device 03 and the fan 7 are both arranged outside the cavity 11. The deodorizing device in this embodiment can adopt any deodorizing device in the existing garbage disposer, and will not be described in detail in this embodiment.

[0063] The garbage disposer of this embodiment is provided with a Bluetooth module for sensing whether there is someone in the kitchen. The signal output end of the Bluetooth module is electrically connected to the controller, and the controller is electrically connected to the second motor.

[0064] The working process of the above garbage disposal is as follows:

[0065] The user pours kitchen waste into the garbage disposer and starts the power supply. The second motor 91 and the heating plate 8 work at the same time. Driven by the second motor, and driven by the driving gear 92, the connecting shaft 93, the first transmission gear 94, the driven gear 95 and the second transmission gear 96, the rotating shaft 2 is driven to rotate. At this time, the first cutting knife 31 and the second cutting knife 32 rotate with the rotating shaft 2, thereby stirring, cutting and grinding the garbage in the cavity 11, and finally cutting the garbage into granular powder. The cut powder is discharged through the discharge port (not marked) of the garbage disposer. The odor in the cavity 11 enters the cavity 41 through the inlet 411 on the fixed knife 4, and is then discharged through the discharge port 412, deodorized by the deodorization device 03, and finally discharged after the fan 7.
