Description

Technical Field

[0001] The utility model belongs to the technical field of daily necessities and relates to a garbage disposer. Background Art

[0002] In daily life, in order to reduce the pollution of kitchen waste to the kitchen environment and prevent solid waste from clogging the pipes, a garbage disposer is installed under the sink to crush the solid waste, and the crushed solid waste is discharged from the pipe along with the liquid.

[0003] The garbage disposer includes a main unit and an inlet, the inlet is fixedly connected to the bottom of the sink, the main unit is fixedly connected to the lower end of the inlet, and the garbage in the sink enters the main unit of the garbage disposer through the inlet. The inlet is equipped with a water plug. When water needs to be stored in the sink, the water plug is installed at the inlet to block the inlet. When it is necessary to process kitchen waste and drain water, the water plug is taken out to open the inlet. For example, a garbage disposer with a publication number of CN210658561U or a publication number of CN204017947U disclosed in Chinese patent literature, a motor is installed at the bottom of the main unit, and a grinding disc is connected to the rotating shaft of the motor. Among them, a flange is provided at the inlet of the main unit housing, and a ring-shaped lower flange is clamped on the flange, and three inwardly protruding blocks are provided on the lower flange. The inlet device includes a feeding cylinder, which is provided with an upper flange and a mounting flange. The mounting flange is axially positioned on the feeding cylinder through a retaining ring. The mounting flange is provided with an inclined clamping strip corresponding to the clamping block. The clamping block on the lower flange is clamped on the inclined clamping strip to connect the host to the inlet device. A lug is provided on the mounting flange between two adjacent inclined clamping strips. Each lug is threadedly connected with a connecting bolt. The rod of the connecting bolt passes through the lug and abuts against the upper flange.

[0004] Garbage disposers generally use a manual switch to turn on or off the motor. This can easily cause the motor to be turned on when the water plug does not block the feeding tube, causing the crushed garbage to splash out through the feeding tube, and even other objects or hands to enter the main unit when the garbage disposer is working. In order to improve the safety of use, engineers have modified the structure of the feeding tube, such as the safety protection device of the garbage disposer with the announcement number CN210797759U proposed in the Chinese patent literature, in which a switch slot is opened on the main connecting ring, the magnetic switch is accommodated in the switch slot, the magnetic switch is electrically connected to the motor of the garbage disposer, the outer ring surface of the water receiving ring matches the inner ring surface of the main connecting ring, and the water receiving ring is provided with a flushing groove matching the position of the switch slot, the flushing groove is concave toward the inner side of the water receiving ring, and the flushing groove covers the magnetic switch. The protective cover includes a side ring, a bottom plate and a permanent magnet, the permanent magnet is arranged in the side ring, the bottom plate is located at the bottom of the side ring, and the outer ring surface of the side ring at the position of the permanent magnet is opened with a positioning groove, and the positioning groove extends to the bottom of the bottom plate.

[0005] The main connecting ring and the water receiving ring are the feeding barrel of the inlet device, and the magnetic switch is the switch sensor. When the above-mentioned safety protection device is used in conjunction with the garbage disposer, when the protective cover is not covered in the water receiving ring, the magnetic switch is in a normally open state, and the motor of the garbage disposer is disconnected and cannot be started; after the protective cover is covered in the water receiving ring, the punching groove is embedded in the positioning groove, and the permanent magnet and the magnetic switch are accurately aligned, so that the magnetic switch can sense the magnetic field of the permanent magnet and change to a closed state, thereby connecting the motor of the garbage disposer. In order to install the magnetic switch, it is necessary to open a switch groove and a punching groove on the main connecting ring and the water receiving ring respectively, and the punching groove forms a bulge on the inner side of the water receiving ring, which makes it easy for garbage to get caught on the bulge when entering the water receiving ring, and the setting of the switch groove and the punching groove is easy to cause a notch effect, resulting in a weakening of the structural strength of the main connecting ring at the switch groove, and a weakening of the structural strength of the water receiving ring at the punching groove, affecting the stability of the feeding barrel structure. In order to reduce the adverse effects of the protrusion, the conventional practice is to increase the wall thickness of the water receiving ring so that the protrusion at the punching groove is flush with the inner side of the water receiving ring. However, this will cause the inner hole diameter of the water receiving ring to become smaller, and at the same time, the structural strength of the main receiving ring at the switch slot is not improved. In addition, when the protective cover is put into the water receiving ring, the positioning groove must be aligned with the protrusion, which is inconvenient to operate. When the switch slot is in an open state, the magnetic switch inside is easy to fall out during the vibration of the garbage disposer. At the same time, the magnetic switch is small in size and the opening of the switch slot is also small, which is inconvenient to install. Utility Model Content

[0006] The utility model aims to solve the above problems in the prior art and proposes a garbage disposer, which solves the technical problem of how to make the switch sensor easy to install and stably fixed while ensuring the stability of the feeding barrel structure.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A garbage disposer comprises a feeding barrel, wherein an upper flange and a mounting flange are sequentially mounted on the outer side of the feeding barrel in the up-down direction, and connecting bolts are connected between the upper flange and the mounting flange. The garbage disposer is characterized in that it also comprises an induction box in which a switch sensor is installed, and the induction box is located between the upper flange and the mounting flange, and the induction box has a mating surface that matches the outer side surface of the feeding barrel, and the induction box has a connecting portion that is sleeved with the connecting bolt, and a fastener is threadedly connected to the connecting bolt, and the fastener abuts against the connecting portion to press the induction box onto the mounting flange.

[0009] When installing the garbage disposer, the feeding barrel is inserted into the drain hole of the sink, the upper flange and the mounting flange are located below the sink, and the connecting bolts are tightened to make the upper flange abut against the lower surface of the sink, so that the feeding barrel, the upper flange and the mounting flange are fixed on the sink, and then the main unit of the garbage disposer is connected to the mounting flange. The switch sensor is installed in the induction box, and fixing the induction box is to fix the switch sensor. When installing the induction box, the mating surface of the induction box is close to or close to the outer side of the feeding barrel, and the connecting part is sleeved on the connecting bolts to radially and circumferentially position the induction box and the feeding barrel, and then tighten the fasteners, and the fasteners abut against the connecting part to make the induction box tightly abut against the mounting flange, so that the induction box and the mounting flange are axially positioned, so that the induction box can be stably fixed on the garbage disposer. Moreover, compared with the switch sensor, the induction box is larger in size, and it is convenient and stable to hold during installation, so that the induction box is easy to install on the garbage disposer. And the fixing of the induction box does not require changing the structure of the feeding barrel, so that the structure of the feeding barrel remains stable. In addition, the induction box also protects the switch sensor, preventing impurities in the environment from contaminating the switch sensor, making the switch sensor work stably and sensitively. Therefore, the garbage disposal can ensure the stability of the feeding barrel structure while making the switch sensor easy to install and stable, and can also ensure that the switch sensor works stably and sensitively.

[0010] In the above-mentioned garbage disposer, a positioning groove corresponding to the connecting bolt is provided on the side of the connecting part, and the connecting bolt can enter the positioning groove through the notch of the positioning groove. When installing, place the induction box on the mounting flange, and make the mating surface face the feeding tube, and the notch of the positioning groove face the connecting bolt, and then push the induction box so that the mating surface is close to or close to the outer side of the feeding tube, and at the same time, the connecting bolt enters the positioning groove, and then tighten the fastener. The setting of the positioning groove makes it easy to install the induction box on the garbage disposer.

[0011] In the above-mentioned garbage disposer, the mating surface has a protruding abutting protrusion, and the abutting protrusion abuts against the outer surface of the feeding barrel. The abutting protrusion has the function of determining the positioning position of the induction box and the feeding barrel, so as to avoid the problem of uncertain positioning position of the mating surface and the outer surface of the feeding barrel caused by processing errors such as concentricity errors. The abutting protrusion stabilizes the radial positioning between the induction box and the feeding barrel, which is conducive to fixing the induction box on the garbage disposer stably, that is, fixing the switch sensor on the garbage disposer stably.

[0012] In the above garbage disposer, a groove is provided on the upper surface of the connection part, and a protruding boss is provided on the lower end surface of the fastener, the boss is inserted into the groove, the lower end surface of the boss abuts against the bottom surface of the groove, and the lower end surface of the fastener abuts against the upper surface of the connection part. The boss can increase the thread length of the fastener, stabilize the connection of the fastener, and thus stabilize the axial positioning of the fastener to the induction box.

[0013] In the above-mentioned garbage disposer, the fastener is made of plastic or rubber, and an opening is provided on the fastener to disconnect the side wall of the fastener, and the connecting bolt can enter the fastener through the opening. The fastener made of plastic or rubber has a certain elasticity, so it is convenient for the connecting bolt to enter the fastener through the opening, so that the fastener can be installed on the connecting bolt at a position close to the induction box, reducing the number of turns when the fastener fixes the induction box, so that the induction box is fixed stably and easy to install. In addition, the fastener is made of plastic or rubber, and the lower end face of the combined boss abuts against the bottom surface of the groove, and the lower end face of the fastener abuts against the upper surface of the connecting part, so that the boss is in an elastic compression state, so that the inner thread of the boss can be more tightly engaged with the thread of the connecting bolt, so that the induction box is fixed more stably.

[0014] In the above-mentioned garbage disposer, there are several connecting bolts which are arranged in sequence along the circumference of the mounting flange. The induction box has two connecting parts which are respectively socketed with two adjacent connecting bolts. The mating surface is located between the two connecting parts, and the positioning grooves on the two connecting parts are arranged in parallel.

[0015] The two connecting parts are respectively connected to the connecting bolts to enhance the circumferential positioning effect, so that the induction box can be stably fixed on the garbage disposer. During installation, the induction box can still be placed on the mounting flange, with the mating surface facing the feeding barrel, the notches of the two positioning grooves facing the two adjacent connecting bolts, and then the induction box is pushed so that the mating surface is close to or close to the outer side of the feeding barrel, and the connecting bolt enters the positioning groove. The induction box is still very convenient to install on the garbage disposer.

[0016] In the above-mentioned garbage disposer, the sensing box includes a main body and a bottom cover, the mating surface and the connecting portion are both arranged on the main body, a mounting groove is arranged on the lower surface of the main body, a positioning seat is arranged in the mounting groove near the mating surface, the switch sensor is embedded in the positioning seat, and the bottom cover is clamped at the notch of the mounting groove to fix the switch sensor in the positioning seat.

[0017] Put the switch sensor into the positioning seat, and then close the bottom cover to install and fix the switch sensor into the induction box. The installation is convenient. At the same time, the switch sensor is fixed by the positioning seat and the bottom cover, so that the switch sensor is fixed and stable. In addition, the positioning seat is close to the mating surface, so that the switch sensor is close to the mating surface and the feeding barrel, so that the switch sensor can sense accurately and sensitively, and the garbage disposer can work stably.

[0018] In the above-mentioned garbage disposer, a removable water plug is provided in the feeding barrel, and the water plug includes a main body inserted in the feeding barrel, a rotatable lifting rod is passed through the center of the main body, a rotating part is circumferentially fixed to the lower end of the lifting rod, the upper end of the lifting rod extends out of the main body, and the outer edge of the rotating part is close to the feeding barrel and is provided with a sensing part that can be sensed by the switch sensor.

[0019] After the garbage is put into the garbage disposer through the feeding barrel, when the garbage disposer needs to be turned on, the water plug is first inserted into the feeding barrel, and then the lifting rod is turned to rotate the rotating part until the sensing part is close to the switch sensor and is sensed, and the switch sensor sends a start signal to start the garbage disposer. The setting of the rotating part does not require changing the structure of the feeding barrel, so that the feeding barrel structure remains stable. In addition, when the water plug is inserted into the feeding barrel, a specific circumferential position is not required, which makes the water plug easy to insert.

[0020] In the above garbage disposer, the outer edge of the rotating part has a convex ring protruding upward, and the induction part is embedded in the convex ring. The provision of the convex ring provides the induction part with sufficient installation space, and the convex ring protrudes upward to prevent the induction part from falling out of the lower end of the rotating part during use, thereby making the induction part stable to install. In addition, the convex ring also has the function of reinforcing ribs, making the outer edge structure of the rotating part stable.

[0021] In the above-mentioned garbage disposer, a plurality of slots are circumferentially arranged on the inner side surface of the convex ring, and a positioning ring is arranged on the inner side of the convex ring on the lower surface of the body, and an elastic positioning member is fixed on the positioning ring. As the rotating member rotates, the elastic positioning member continuously slides out of one slot and enters another adjacent slot. The elastic positioning member is subjected to different forces during the sliding process on the inner side surface of the convex ring, which can increase the feel of rotation and make it convenient for the operator to use. In addition, after the sensing member is rotated to be sensed by the switch sensor, the elastic positioning member is embedded in one of the slots, which can position the rotating member and prevent the rotating member from rotating at will.

[0022] In the above-mentioned garbage disposer, the mounting flange is connected to a main unit, the main unit includes a shell, a grinding disc is installed in the shell, a motor is fixed in the shell below the grinding disc, a water inlet joint is arranged on the shell above the grinding disc, an outer pipe joint is arranged at the bottom of the shell, a groove is arranged on the outer side of the shell, a water inlet pipe is embedded in the groove, the two ends of the water inlet pipe are respectively connected to the water inlet joint and the outer pipe joint, and a jacket covering the water inlet pipe and the water inlet joint is also set outside the shell. When the switch sensor senses the sensing element, the water inlet joint automatically fills with water and the motor starts to crush and grind the garbage. The water inlet pipe is fixed and protected by the groove and the jacket, so that the water inlet pipe is stable in use.

[0023] Compared with the prior art, the utility model has the following advantages:

[0024] The switch sensor is installed in the induction box, which is fixed to the mounting flange through the mating surface, the connection part and the fasteners. While ensuring the stability of the feeding barrel structure, the switch sensor is easy to install and fixed stably, and it can also ensure that the switch sensor works stably and sensitively. The water plug is easy to insert in the feeding barrel, and it is also very convenient to start the motor and automatically fill water. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The switch sensor 8 is installed in the induction box 7 during factory production. When installing a garbage disposer in the kitchen, the inlet 1 can be installed on the sink first. If the fasteners 9 are made of metal, the two fasteners 9 need to be first fitted onto the corresponding connecting bolts 3, and then the connecting bolts 3 are tightened. If the fasteners 9 are made of plastic or rubber, they can be connected when installing the induction box 7. Then the main unit 18 is fixed to the inlet 1, that is, the block 21a on the lower flange 21 of the main unit 18 is correspondingly connected to the inclined clamping strip 5a of the mounting flange 5. Then fix the induction box 7 on the inlet 1, place the induction box 7 on the upper surface of the mounting flange 5, make the mating surface 7a1 of the induction box 7 face the outer side of the feeding barrel 2, and align the notch of the positioning groove 7a4 on the connecting portion 7a3 with two adjacent connecting bolts 3, then push the induction box 7 so that the mating surface 7a1 of the induction box 7 is close to the outer side of the feeding barrel 2, and the protrusion 7a2 abuts against the feeding barrel 2, and the connecting bolt 3 enters the positioning groove 7a4, so that the induction box 7 and the feeding barrel 2 are radially positioned and circumferentially positioned. If the fastener 9 is made of plastic or rubber, the fastener 9 is set on the connecting bolt 3 through the opening 9b of the fastener 9, and then the fastener 9 is tightened, and the fastener 9 abuts on the connecting portion 7a3 so that the induction box 7 is tightly abutted against the mounting flange 5, so that the induction box 7 and the mounting flange 5 are axially positioned, so that the induction box 7 can be stably fixed on the garbage disposer. Then connect the data line 10 on the induction box 7 to the sensor connector at the bottom of the shell 19. Finally, the external water pipe is connected to the external pipe joint 25, the solenoid valve is connected to the solenoid valve socket 27, and the power cord is connected to the power socket 28. After power is turned on, the garbage disposer is in a standby state.

[0046] When water needs to be collected in the sink for cleaning, first insert the water plug 11 into the feeding tube 2, and press the lifting rod 14 downward, so that the sealing gasket 15a on the filter basket 15 blocks the water hole 12d. At this time, the steel ball 14b on the lifting rod 14 is embedded in the annular groove 12h, which has a positioning effect and prevents the lifting rod 14 from rising at will and causing water leakage. When washing items and water does not need to be collected in the sink, in order to prevent items from accidentally falling into the feeding tube 2 and entering the main machine 18, the water plug 11 can be inserted into the feeding tube 2, and the lifting rod 14 can be pulled up, and the filter basket 15 rises to open the water hole 12d. At this time, the steel ball 14b on the lifting rod 14 is embedded in the annular groove 12g, which has a positioning effect and prevents the sealing gasket 15a from blocking the water hole 12d again after the lifting rod 14 is lowered at will. After cleaning, the entire water plug 11 can be taken out of the feeding tube 2. After all the garbage passes through the feeding tube 2 and enters the main machine 18, the water plug 11 can be put back into the feeding tube 2. Then the lifting rod 14 is rotated, and the rotating member 16 rotates to make the sensing member 17 close to the switch sensor 8. When the switch sensor 8 senses the sensing member 17, the motor 31 starts and the solenoid valve opens. In order to facilitate the operator to identify the sensing situation, a speaker can be connected to the control panel 29. When the switch sensor 8 senses the sensing member 17, the speaker emits a prompt sound.

[0047] In this garbage disposal, the volume of the induction box 7 is relatively large, and it is convenient and stable to hold during installation, so that the switch sensor 8 is easy to install on the garbage disposal. In addition, the fixation of the induction box 7 and the use of the water plug 11 do not require changing the structure of the feeding barrel 2, so that the structure of the feeding barrel 2 remains stable. In addition, the induction box 7 also has a protective effect on the switch sensor 8, preventing impurities in the environment from contaminating the switch sensor 8, so that the switch sensor 8 works stably and sensitively. Therefore, this garbage disposal can ensure that the structure of the feeding barrel 2 is stable while making the switch sensor 8 easy to install and stable to fix, and can also ensure that the switch sensor 8 works stably and sensitively.
