Description
Technical Field
[0001] The present invention relates to the technical field of household electrical appliances, and in particular to a garbage disposer. Background Art
[0002] Food waste disposers, also known as garbage disposers, are gaining increasing acceptance as waste sorting policies mandate this. They pulverize food waste and dispose of it directly into the sewer, reducing the inconvenience of waste sorting and disposal. A motor drives the grinding disc to grind the waste into a powder, which then flows through the holes in the grinding chamber into the drainpipe. Inadequate grinding can clog the drainpipe and the holes in the grinding chamber, affecting grinding efficiency and making cleaning difficult. Summary of the Invention
[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the garbage disposer in the prior art that insufficiently ground garbage may enter the drain pipe during the garbage grinding process and cause the drain pipe to be blocked, thereby providing a garbage disposer that can prevent insufficiently ground garbage from entering the drain pipe during the garbage grinding process.
[0004] In order to solve the above technical problems, the present invention provides a garbage disposer, comprising: a grinding chamber having a through hole; a permanent magnet grinding disc, rotatably arranged in the grinding chamber and having an initial position and a suspended position, wherein the permanent magnet grinding disc blocks the through hole when the permanent magnet grinding disc is in the suspended position; a driving structure, connected to the permanent magnet grinding disc, for driving the permanent magnet grinding disc to rotate; an electromagnetic induction coil, arranged in the grinding chamber, wherein when the permanent magnet grinding disc rotates, the electromagnetic induction coil induces current to generate an induced magnetic field to move the permanent magnet grinding disc from the initial position to the suspended position.
[0005] Optionally, the electromagnetic induction coil is in an "8" shape, including an upper ring and a lower ring, and when the permanent magnet grinding disk is in the initial position, the permanent magnet grinding disk is located on the inner side of the lower ring.
[0006] Optionally, the electromagnetic induction coil is formed by folding a ring coil.
[0007] Optionally, a plurality of electromagnetic induction coils are provided and are evenly distributed along the circumference of the permanent magnet grinding disc.
[0008] Optionally, each of the electromagnetic induction coils is a multi-turn coil.
[0009] Optionally, the driving structure can rise and fall along with the permanent magnet grinding disc.
[0010] Optionally, the garbage disposer further includes an installation cavity, which is located below the grinding cavity and separated from the grinding cavity. A slide rail is provided in the installation cavity, and the driving structure is arranged on the slide rail.
[0011] Optionally, the driving structure is a motor, and the rotating shaft of the motor is fixedly connected to the permanent magnet grinding disc.
[0012] Optionally, the garbage disposer further includes a controller, which is communicatively connected to the drive structure, and the controller can control the drive structure to stop working after the drive structure has worked for a preset time.
[0013] Optionally, the controller is installed at the bottom of the installation cavity.
[0014] The technical solution of the present invention has the following advantages:
[0015] 1. The garbage disposer provided by the present invention has a drive structure that drives the permanent magnet grinding disc to rotate. When the permanent magnet grinding disc rotates, the coil moves relative to the permanent magnet grinding disc, causing the coil to cut the magnetic flux lines to generate an induced current. The induced current generates an induced magnetic field. Under the action of gravity and the magnetic force of the magnetic field, the permanent magnet moves from the initial position to the suspended position, and continues to rotate at the suspended position to grind and crush the garbage. When in the suspended position, the permanent magnet grinding disc blocks the through hole, and the unground garbage cannot enter the drain pipe through the through hole, thereby avoiding clogging of the drain pipe. When grinding is completed, the drive structure stops working, and under the action of gravity, the permanent magnet grinding disc returns to its initial position. The ground and crushed garbage can be discharged into the drain pipe through the through hole. Since the garbage has been fully ground, it can avoid clogging of the sewer pipe. At the same time, when the coil cuts the magnetic flux lines to generate an induced current, it can heat the grinding chamber, solving the problem of bacterial growth in the grinding chamber.
[0016] 2. The garbage disposer provided by the present invention, wherein the electromagnetic induction coil is in the shape of an "8", including an upper ring and a lower ring, and when the permanent magnet grinding disc is in the initial position, the permanent magnet grinding disc is located on the inner side of the lower ring. In this embodiment, when the permanent magnet grinding disc is in the initial position, the permanent magnet grinding disc is located on the inner side of the lower ring. When the permanent magnet grinding disc starts to rotate, the upper and lower rings of the coil simultaneously cut the magnetic flux lines, and the change in the magnetic flux of the lower ring is greater than the change in the magnetic flux of the upper ring. The direction of the induced current generated in the coil and the direction of the induced magnetic field generated by the upper and lower rings are shown in the figure. The magnetic field generated by the lower ring produces a repulsive force on the permanent magnet grinding disc, and the magnetic field generated by the upper ring produces an attractive force on the permanent magnet grinding disc, thereby overcoming the gravity of the permanent magnet grinding disc and causing the permanent magnet grinding disc to float. When the permanent magnet grinding disc floats to the inner side of the upper ring, the induced current generated by the upper ring is greater than the induced current generated by the lower ring, and the permanent magnet grinding disc descends and eventually suspends. When the grinding is completed, the driving structure stops working, and the permanent magnet grinding disk continues to rotate by inertia, the speed gradually decreases, the change in magnetic flux of the upper ring and the lower ring decreases, and the magnetic field force of the induced magnetic field formed by the upper ring and the lower ring on the permanent magnet grinding disk decreases. Under the action of gravity, the permanent magnet grinding disk returns to its initial position. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example
[0031] Food waste disposers, also known as garbage disposers, are gaining increasing acceptance as waste sorting policies mandate this. They pulverize food waste and dispose of it directly into the sewer, reducing the inconvenience of waste sorting and disposal. A motor drives the grinding disc to grind the waste into a powder, which then flows through the holes in the grinding chamber into the drainpipe. Inadequate grinding can clog the drainpipe and the holes in the grinding chamber, affecting grinding efficiency and making cleaning difficult.
[0032] To this end, this embodiment provides a garbage disposer that can prevent insufficiently ground garbage from entering the drain pipe 9 during the garbage grinding process.
[0033] In one embodiment, Figures 1 to 6 As shown, the garbage disposer includes a grinding chamber 1, a permanent magnet grinding disc 2, a drive structure, and an electromagnetic induction coil 4. The grinding chamber 1 has a through hole. The permanent magnet grinding disc 2 is rotatably disposed within the grinding chamber 1 and has an initial position and a suspended position. When the permanent magnet grinding disc 2 is in the suspended position, the through hole is blocked. The drive structure is connected to the permanent magnet grinding disc 2 and is used to drive the permanent magnet grinding disc 2 to rotate. The electromagnetic induction coil 4 is disposed within the grinding chamber 1. When the permanent magnet grinding disc 2 rotates, the electromagnetic induction coil 4 induces a current to generate an induced magnetic field, causing the permanent magnet grinding disc 2 to move from the initial position to the suspended position.
[0034] In this embodiment, when the garbage disposer is in operation, the drive structure drives the permanent magnet grinding disc 2 to rotate. As the permanent magnet grinding disc 2 rotates, the coil moves relative to the permanent magnet grinding disc 2, causing the coil to cut through the magnetic flux lines, generating an induced current. The induced current generates an induced magnetic field. Under the influence of gravity and the magnetic force of the magnetic field, the permanent magnet moves from its initial position to a suspended position, where it continues to rotate and grind the garbage. In the suspended position, the permanent magnet grinding disc 2 blocks the through hole, preventing unground garbage from passing through the through hole into the drain pipe 9, thus preventing clogging of the drain pipe 9. When grinding is complete, the drive structure stops, and under the influence of gravity, the permanent magnet grinding disc 2 returns to its initial position. The ground garbage can be discharged through the through hole into the drain pipe 9. Since the garbage is fully ground, clogging of the sewer pipe is avoided. At the same time, when the coil cuts through the magnetic flux lines, generating the induced current, it can heat the grinding chamber 1, solving the problem of bacterial growth in the grinding chamber 1.
[0035] On the basis of the above embodiment, in a preferred embodiment, the electromagnetic induction coil 4 is in the shape of an "8", including an upper ring 401 and a lower ring 402. When the permanent magnet grinding disc 2 is in the initial position, the permanent magnet grinding disc 2 is located on the inner side of the lower ring 402. In this embodiment, when the permanent magnet grinding disc 2 is in the initial position, the permanent magnet grinding disc 2 is located on the inner side of the lower ring 402. When the permanent magnet grinding disc 2 starts to rotate, the upper ring 401 and the lower ring 402 of the coil simultaneously cut the magnetic flux lines. The change in the magnetic flux of the lower ring 402 is greater than the change in the magnetic flux of the upper ring 401. The direction of the induced current generated in the coil and the direction of the induced magnetic field generated by the upper ring 401 and the lower ring 402 are as shown in FIG. Figure 6 As shown, the magnetic field generated by the lower ring 402 exerts a repulsive force on the permanent magnet grinding disc 2, while the magnetic field generated by the upper ring 401 generates an attractive force on the permanent magnet grinding disc 2, thereby overcoming the gravity of the permanent magnet grinding disc 2 and causing it to float upward. When the permanent magnet grinding disc 2 floats to the inside of the upper ring 401, the induced current generated by the upper ring 401 is greater than the induced current generated by the lower ring 402, causing the permanent magnet grinding disc 2 to descend and eventually levitate. In the suspended position, the permanent magnet grinding disc 2 blocks the through hole, preventing unground garbage from passing through the through hole and entering the drain pipe 9, thus preventing clogging of the drain pipe 9. After grinding is complete, the drive mechanism stops, and the permanent magnet grinding disc 2 continues to rotate due to inertia, gradually decreasing its speed. The change in magnetic flux between the upper ring 401 and the lower ring 402 decreases, and the magnetic field force exerted on the permanent magnet grinding disc 2 by the induced magnetic field formed by the upper ring 401 and the lower ring 402 decreases. Under the action of gravity, the permanent magnet grinding disc 2 returns to its initial position, and the ground and pulverized waste is discharged through the hole into the drain pipe 9. Because the waste is fully ground, clogging of the sewer pipe is avoided.
[0036] It should be noted that the upper ring 401 and the lower ring 402 can be various ring shapes such as a circular ring, a rectangular ring, etc.
[0037] On the basis of the above embodiment, in a preferred embodiment, as Figure 4 and Figure 5 As shown, the electromagnetic induction coil 4 is formed by folding the annular coil 5. In this embodiment, the formation of the electromagnetic induction coil 4 is simple and easy to operate. In other alternative embodiments, the electromagnetic induction coil 4 can be formed by connecting two annular coils 5.
[0038] Based on the above embodiment, in a preferred embodiment, a plurality of electromagnetic induction coils 4 are provided and are evenly distributed along the circumference of the permanent magnet grinding disk 2. In this embodiment, by providing a plurality of electromagnetic induction coils 4 and evenly distributing them along the circumference of the permanent magnet grinding disk 2, the magnetic force applied to the permanent magnet grinding disk 2 can be made uniform, thereby preventing the permanent magnet grinding disk 2 from deflecting.
[0039] Based on the above embodiment, in a preferred embodiment, each electromagnetic induction coil 4 is a multi-turn coil. In this embodiment, by making each electromagnetic induction coil 4 a multi-turn coil, the strength of the generated induced magnetic field can be ensured.
[0040] Based on the above embodiment, in a preferred embodiment, the drive structure can be raised and lowered along with the permanent magnet grinding disc 2. In this embodiment, by having the drive structure rise and fall along with the permanent magnet grinding disc 2, the permanent magnet grinding disc 2 drives the drive structure along with it during the raising and lowering process. This allows for a relatively simple connection between the drive structure and the permanent magnet grinding disc 2, requiring only a fixed connection between the two. In other alternative embodiments, it is possible to consider a fixed arrangement of the drive structure, allowing the permanent magnet to rise and fall relative to the drive structure and to rotate under the drive structure's drive.
[0041] Based on the above embodiment, in a preferred embodiment, the garbage disposer further includes a mounting chamber 6, which is located below and separated from the grinding chamber 1. A slide rail 7 is provided in the mounting chamber 6, and the drive structure is disposed on the slide rail 7. In this embodiment, the slide rail 7 can guide and limit the raising and lowering of the drive structure, preventing deflection during the raising and lowering process.
[0042] Based on the above embodiment, in a preferred embodiment, the drive structure comprises a motor 3, and the rotating shaft 301 of the motor 3 is fixedly connected to the permanent magnet grinding disc 2. In this embodiment, the drive structure comprises only the motor 3, which is simple in structure and easy to control. Of course, in other alternative embodiments, the drive structure includes not only the motor 3 but also a transmission structure connected between the rotating shaft 301 of the motor 3 and the permanent magnet grinding disc 2, so that the transmission structure can transmit the rotation of the motor 3 to the permanent magnet grinding disc 2.
[0043] In a preferred embodiment, based on the above embodiment, the garbage disposer further includes a controller 8, which is in communication with the drive mechanism and is capable of controlling the drive mechanism to stop operating after the drive mechanism has operated for a predetermined period of time. In this embodiment, the configuration of the controller 8 enables automatic control, eliminating the need for the user to manually shut down the drive mechanism.
[0044] Specifically in one embodiment, when the driving structure is only the motor 3, the controller 8 is in communication with the motor 3 and can control the motor 3 to stop working after the motor 3 has worked for a preset time.
[0045] Based on the above embodiment, in a preferred embodiment, the controller 8 is installed at the bottom of the installation cavity 6. In this embodiment, the controller 8 is installed at the bottom of the installation cavity 6. The controller 8 is close to the motor 3, which is convenient for connecting to the motor 3 and controlling the motor 3.
[0046] In a preferred embodiment, the controller 8 can be connected to the water inlet valve to realize the automatic water inlet function. During the grinding process, the speed of the motor 3 can be adjusted by the controller 8 to expose part of the through hole, so that some garbage can enter the drain pipe 9 through the through hole first.
[0047] Based on the above embodiment, in a preferred embodiment, the through hole is connected to a drain pipe 9 .
[0048] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
