Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, and in particular to a feeding device for a waste processor and a control method for the waste processor. Background Technology

[0002] As people's living standards improve, the demand for smart kitchens is increasing, leading to the widespread use of smart appliances such as smart rice cookers and smart dishwashers. Kitchen waste, mostly organic matter, is prone to bacterial growth, producing unpleasant odors, and its complex composition makes sorting difficult, making it a major component of household waste and thus requiring corresponding products for processing. With the implementation of waste sorting policies across various regions, sales of sorting bins and waste disposers have increased significantly, and food waste disposers are being purchased and used by more and more users. Existing food waste disposers come in various types, among which direct-discharge disposers grind waste and discharge it directly into the sewer, offering some convenience. Most existing food waste disposers rely on a pull-type feeder to assist in feeding food waste into the disposer. While the pull-type feeder can assist in feeding food into the grinding chamber to some extent, it is cumbersome for users, resulting in a poor user experience. Furthermore, the grinding noise generated during the pulling process is intermittent, further complicating the user experience. In addition, existing food waste disposers cannot adjust the rotation speed of the grinding disc according to the speed at which food waste is put in, resulting in a low level of intelligence and insufficient energy efficiency. Summary of the Invention

[0003] The first technical problem to be solved by the present invention is to provide a feeding device for a waste disposer that has high feeding efficiency and good noise reduction effect, in view of the above-mentioned existing technology.

[0004] The second technical problem to be solved by the present invention is to provide a control method for a garbage disposer that can adjust the motor speed according to the garbage input speed to achieve efficient and precise grinding, in light of the aforementioned existing technology.

[0005] The technical solution adopted by the present invention to solve the first technical problem mentioned above is as follows: The feeding device for a garbage disposer includes a garbage disposer located at the bottom of a water tank. The bottom of the water tank has an installation hole. The feeding port at the top of the garbage disposer is installed on the installation hole through an installation component. The device is characterized in that it further includes a feeder bracket, a feeder, and a feeding agitator. The lower part of the feeder bracket is installed on the installation component. The upper part of the feeder bracket extends upward through the installation hole and into the water tank. The feeder is located inside the water tank and is rotatably connected to the feeder bracket. A feeding channel communicating with the feeding port is formed between the feeder and the bottom of the water tank. The feeding agitator is fixed to the bottom of the feeder and can rotate synchronously with the feeder. The feeding agitator extends into the feeding port. A distance sensor capable of sensing changes in the position of the feeding agitator is installed on the outer wall of the feeding port.

[0006] The distance sensor can be installed in multiple different locations. Preferably, the waste disposer includes a grinding cover, the top of which forms the feeding port, and the distance sensor is installed on the outer wall of the grinding cover.

[0007] The feeding agitator can have various structures. To ensure that the signal detected by the distance sensor changes continuously as the feeding agitator rotates, the feeding agitator is cylindrical with an oblique cut on its side. The top of the oblique cut is near the top of the feeding agitator, and the bottom of the oblique cut is located at the bottom of the feeding agitator. The bottom of the feeding agitator is located within the sensing area of ​​the distance sensor. In this way, the distance sensor can detect changes in the position of the feeding agitator, and the detected signal will change periodically.

[0008] In order to allow some of the water carried in the waste to flow into the grinding chamber through the water passage holes, water passage holes distributed in a mesh pattern are opened on the side wall of the feeding agitator.

[0009] The feeding agitator and the feeder can have various different mating structures. Preferably, the feeding agitator has an outwardly flared protrusion on its upper edge, and the protrusion has circumferentially spaced locking slots. The feeder has a latch at its bottom, which engages with the corresponding locking slots, allowing the feeding agitator to rotate synchronously with the feeder. This makes assembly and disassembly of the feeding agitator and the feeder very convenient, and ensures reliable synchronous rotation.

[0010] Preferably, the feeder support has a feed hole on its peripheral wall, and the feed channel is connected to the feed inlet through the feed hole. In this way, kitchen waste in the sink can enter the feed inlet through the feed channel and feed hole, and then enter the grinding chamber of the garbage disposal unit for processing.

[0011] In order to ensure that food waste can enter the garbage disposal unit evenly from all directions, the feed holes are distributed at intervals along the circumference of the feeder support.

[0012] In order to mount the feeder bracket on the mounting assembly and allow the feeder to rotate relative to the feeder bracket, the top of the feeder bracket is an upper annular wall, and the bottom of the feeder is provided with a circular limiting groove. The upper annular wall is limited within the circular limiting groove so that the feeder can rotate circumferentially relative to the feeder bracket. The bottom of the feeder bracket is a lower annular wall, and the feed hole is located on the circumferential wall between the upper and lower annular walls. The lower annular wall is mounted on the mounting assembly.

[0013] For ease of operation, the feeder is disc-shaped, with a rotating handle protruding upwards from the top. Preferably, multiple rotating handles can be provided and arranged at intervals along the circumference.

[0014] To rotate the waste in the feeding channel into the grinding chamber, the bottom of the feeder is provided with a downward-protruding rotating arm, which is spaced out circumferentially. When the feeder rotates, the rotating arms can effectively drive the kitchen waste to rotate inward, and the kitchen waste is smoothly carried into the grinding chamber.

[0015] The technical solution adopted by the present invention to solve the second technical problem mentioned above is: a control method for a garbage disposal unit, wherein the garbage disposal unit includes a grinding chamber and a grinding disc disposed in the grinding chamber, the grinding disc rotating under the drive of a motor, characterized in that: the garbage disposal unit is equipped with the feeding device, and the control method includes the following steps:

[0016] S1. Power on;

[0017] S2, The distance sensor detects the current distance di of the feeding agitator;

[0018] S3. Determine whether di is less than dm, where dm is the preset distance value of the feeding agitator;

[0019] If so, the motor will not run;

[0020] If not, proceed to step S4;

[0021] S4. The distance sensor detects the rate of change kdi of the current distance to the feeding agitator.

[0022] S5. Determine whether kdi is less than kdm1, where kdm1 is the minimum rate of change of the distance of the feeding agitator;

[0023] If so, it means that the feeder rotates at a slow speed, the amount of garbage being fed is small, and the motor is running at the default speed.

[0024] If not, proceed to step S6;

[0025] S6. Determine whether kdi satisfies kdm1 < kdi < kdm2, where kdm2 is the maximum change rate of the distance of the feeding agitator;

[0026] If so, it means that the rotation speed of the feeder is within a reasonable range, and the motor runs at the default medium gear;

[0027] If not, go to step S7;

[0028] S7. kdi > kdm2 indicates that the rotation speed of the feeder increases and the garbage delivery volume increases, and the motor runs at the default high gear;

[0029] S8. When the motor reaches the running time, shut down.

[0030] Compared with the prior art, the advantages of the present invention are as follows: The feeder of the feeding device for the garbage processor is arranged inside the sink and is rotatably connected to the feeder bracket. The feeding agitator is fixed at the bottom of the feeder and can rotate synchronously with the feeder. The rotation of the feeding agitator causes the signal detected by the distance sensor to change periodically. This control method can judge the speed of input kitchen waste according to the detected distance of the feeding agitator and its change rate, and then achieve precise matching control of the motor speed, with better energy-saving effect. Moreover, the noise generated during the grinding process can be significantly reduced in proportion to the human ear under the shielding effect of the feeder, and the noise reduction effect is obvious.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] like Figures 1 to 6 As shown, the feeding device for the garbage disposal unit in this embodiment includes a garbage disposal unit 2 located at the bottom of a water tank 1. A mounting hole 11 is provided at the bottom of the water tank 1, and the feeding port 21 at the top of the garbage disposal unit 2 is mounted on the mounting hole 11 via a mounting assembly 3. The lower part of a feeder bracket 4 is mounted on the mounting assembly 3, and the upper part of the feeder bracket 4 extends upward through the mounting hole 11 and into the water tank 1. A feeder 5 is located inside the water tank 1 and rotatably connected to the feeder bracket 4. A feeding channel 8 is formed between the feeder 5 and the bottom of the water tank 1. A feeding agitator 6 is fixed to the bottom of the feeder 5 and can rotate synchronously with the feeder 5. The feeding agitator 6 extends into the feeding port 21, and a distance sensor 7 capable of sensing changes in the position of the feeding agitator 6 is installed on the outer wall of the feeding port 21.

[0040] In this embodiment, the waste processor 2 includes a grinding cover 20, with a feeding port 21 formed on the top of the grinding cover 20. A distance sensor 7 is mounted on the outer wall of the grinding cover 20. The distance sensor 7 consists of a magnet and a Hall sensor. The feeding agitator 6 is made of metal and is cylindrical with a beveled cut 61 on its side. The top of the beveled cut 61 is close to the top of the feeding agitator 6, and the bottom of the beveled cut 61 is located at the bottom of the feeding agitator. The bottom of the feeding agitator 6 is located within the sensing area of ​​the distance sensor 7. After the beveled cut is provided on the feeding agitator 6, when the feeding agitator 6 rotates, the distance sensor 7 can detect the positional change of the feeding agitator 6, and the signal detected by the distance sensor 7 will change periodically. The specific detection principle is existing technology and will not be described in detail here.

[0041] In addition, the side wall of the feeding agitator 6 in this embodiment has water passage holes 62 distributed in a mesh pattern, so that water carried in the waste can partially flow into the grinding chamber through the water passage holes 62.

[0042] The feeding agitator 6 rotates synchronously with the feeder 5. Specifically, the feeding agitator 6 has an outwardly flared protrusion 63 on its upper edge, with circumferentially spaced locking slots 64 on the protrusion 63. The feeder 5 has a latch 50 at its bottom, which engages with the corresponding latch 64, allowing the feeding agitator 6 to rotate synchronously with the feeder 5. The rotation of the feeding agitator 6 effectively prevents kitchen waste from getting stuck in the feeding inlet 21.

[0043] In this embodiment, the feeder bracket 4 has feed holes 41 on its peripheral wall. The feed holes 41 are spaced apart along the circumference of the feeder bracket 4, and the feed channel 6 is connected to the feed inlet 21 through the feed holes 41. The top of the feeder bracket 4 is an upper annular wall 42, and the bottom of the feeder 5 is provided with a circular limiting groove 51. The upper annular wall 42 is limited within the circular limiting groove 51, allowing the feeder 5 to rotate circumferentially relative to the feeder bracket 4. The bottom of the feeder bracket 4 is a lower annular wall 43, and the feed holes 41 are located on the peripheral wall between the upper annular wall 42 and the lower annular wall 43. The lower annular wall 43 is mounted on the mounting assembly 3.

[0044] The feeder 5 in this embodiment is disc-shaped. A rotating handle 52 protrudes upward from the top of the feeder 5. In this embodiment, there are three rotating handles 52, which are spaced apart circumferentially. A rotating arm 53 protrudes downward from the bottom of the feeder 5. In this embodiment, there are three rotating arms 53, which are spaced apart circumferentially.

[0045] like Figure 6 As shown, the waste disposer includes a grinding chamber 22 and a grinding disc 23 disposed in the grinding chamber. The grinding disc 23 rotates under the drive of a motor 24. The waste disposer also includes the aforementioned feeding device.

[0046] When this garbage disposal unit is working, the user can rotate the feeder 5 by rotating the handle 52 on the feeder 5. The rotating arm 53 rotates synchronously, effectively driving the kitchen waste to rotate centripetally. The kitchen waste is smoothly brought into the grinding chamber 22, where it is ground by the rotation of the grinding disc 23 driven by the motor 24. Compared with a pull-type feeder, this feeding device can significantly improve feeding efficiency. It is simple and convenient for users to operate. Furthermore, the noise generated during the grinding process is significantly reduced to the ear due to the shielding effect of the feeder 5, resulting in a noticeable noise reduction effect.

[0047] The control method for this waste disposal unit includes the following steps:

[0048] S1. Power on;

[0049] S2, Distance sensor 7 detects the current distance di of feeding agitator 6;

[0050] S3. Determine whether di is less than dm, where dm is the preset distance value of the feeding agitator 6;

[0051] If so, the motor will not run for 24 hours;

[0052] If not, proceed to step S4;

[0053] S4, Distance sensor 7 detects the rate of change kdi of the current distance to the feeding agitator 6;

[0054] S5. Determine whether kdi is less than kdm1, where kdm1 is the lowest change rate of the distance of the feeding agitator 6;

[0055] If so, it indicates that the rotation speed of the feeder 5 is slow, the garbage delivery volume is small, and the motor 24 operates at the default gear;

[0056] If not, proceed to step S6;

[0057] S6. Determine whether kdi satisfies kdm1 < kdi < kdm2, where kdm2 is the highest change rate of the distance of the feeding agitator 6;

[0058] If so, it indicates that the rotation speed of the feeder 5 is within a reasonable range, and the motor 24 operates at the default medium gear;

[0059] If not, proceed to step S7;

[0060] S7. kdi > kdm2 indicates that the rotation speed of the feeder 5 increases, the garbage delivery volume increases, and the motor 24 operates at the default high gear;

[0061] S8. When the motor 24 reaches the operating time, shut down.

[0062] As can be seen from the above control method, the garbage processor can detect the distance di of the feeding agitator 6 and its change rate Kdi through the distance sensor 7 to judge the speed of the input kitchen waste, so as to accurately match and control the speed of the motor 24, achieve efficient and accurate grinding, and is also beneficial to energy saving.
