Technical Field

[0001] The present invention relates to the technical field of garbage disposal, and in particular to an anti-blocking structure, kitchen garbage disposal equipment and an anti-blocking control method. Background Art

[0002] After using the kitchen garbage disposer for a period of time, oil is likely to accumulate between the grinding disc and the grinding wall. As time goes by, the accumulated oil becomes more and more viscous and more and more, resulting in the ground garbage being unable to be discharged from between the grinding disc and the grinding wall, which is prone to blockage. Since users cannot use tools to clean it, it is difficult to clean it, and it can only be disassembled for cleaning, which often brings great trouble and inconvenience to users. Summary of the invention

[0003] In view of this, the present invention provides an anti-blocking structure, a kitchen waste treatment device and an anti-blocking control method to solve the problem that oil and dirt are easily accumulated between the grinding disc and the grinding wall of the kitchen waste treatment device and are difficult to clean.

[0004] In a first aspect, the present invention provides an anti-blocking structure, which is applicable to a garbage disposal device, wherein the garbage disposal device comprises a grinding wall and a grinding disc, wherein an annular space channel suitable for discharging grinding products is formed between the grinding disc and the grinding wall, and the anti-blocking structure comprises:

[0005] A coil assembly, arranged on the grinding wall and / or the grinding disc;

[0006] A power source electrically connected to the coil assembly, wherein the coil assembly generates a magnetic field between the grinding wall and the grinding disk when powered on;

[0007] The magnetic flow mechanism comprises a magnetic flow storage tank filled with magnetic fluid. After the outlet of the magnetic flow storage tank is opened, the magnetic fluid can flow along the annular channel under the action of the magnetic field to clear the blockage in the annular channel.

[0008] Beneficial effects: A coil assembly is arranged on the grinding wall and / or grinding disc. The coil assembly can generate a magnetic field after being energized. Under the action of the magnetic field, the magnetic fluid can move along the annular channel between the grinding disc and the grinding wall to clean up blockages such as oil stains in the annular channel. The grinding disc does not need to be disassembled for cleaning, which improves the cleaning convenience and enhances the user experience.

[0009] In an optional embodiment, the coil assembly includes:

[0010] A first coil, embedded in the grinding wall;

[0011] and / or a second coil, which is arranged on the peripheral side of the grinding disc close to the grinding wall.

[0012] Beneficial effects: The coil assembly can be arranged on one of the grinding wall and the grinding disk, with a simple structure; the first coil can also be arranged in the grinding wall, and the second coil can be arranged in the grinding disk. Such an arrangement can increase the magnetic field strength, the magnetic force acting on the magnetic fluid is stronger, the dredging effect is better, and the cleaning efficiency can be effectively improved.

[0013] In an optional embodiment, the anti-blocking structure further includes a switching circuit for converting the positive and negative poles of the power supply, and the power supply is arranged in the switching circuit.

[0014] Beneficial effects: The use of an exchange circuit facilitates the control and exchange of the polarity of the power supply, realizes the rapid conversion of the positive and negative poles of the power supply, and then can provide alternating current to the coil. The polarity of the magnetic field can be periodically changed, so that the magnetic fluid can reciprocate up and down in the annular channel, quickly disintegrate the blockage, and effectively improve the cleaning effect and cleaning efficiency.

[0015] In an optional embodiment, the magnetic flow storage tank is arranged above the annular channel.

[0016] Beneficial effects: After the outlet of the magnetic flow storage tank is opened, the magnetic fluid moves more smoothly to the annular channel below it under the action of gravity, thereby increasing the movement speed of the magnetic fluid. Even if the coil is not passing the electromagnetic fluid at this time, the magnetic fluid can still reach the annular channel smoothly; and the gravity can also serve as a supplement to the magnetic field effect, overcoming the insufficient magnetic field strength caused by the distance limitation between the magnetic flow storage tank and the annular channel, so that the magnetic fluid can reach the annular channel smoothly.

[0017] In an optional embodiment, the magnetic flow mechanism further includes a collecting chamber, and the magnetic fluid is suitable for flowing into the collecting chamber under the action of gravity.

[0018] Beneficial effect: After the blockage is cleared, the magnetic fluid flows into the lower collection chamber under the action of gravity, which is convenient for the magnetic fluid to be recycled or collected for treatment.

[0019] In an optional embodiment, the anti-blocking structure further includes a photoelectric sensor or a capacitive sensor for determining a blockage state in the annular channel.

[0020] Beneficial effect: Use photoelectric sensor or capacitance sensor to judge the blockage status of the annular channel. If there is a blockage, the controller will start the coil of the anti-blockage structure to energize and open the outlet of the magnetic flow storage tank for cleaning and dredging.

[0021] In a second aspect, the present invention further provides a kitchen waste treatment device, comprising:

[0022] grinding wall;

[0023] A grinding disc, an annular passage suitable for discharging the grinding product is formed between the grinding disc and the grinding wall;

[0024] The anti-blocking structure described in any of the above items;

[0025] A housing, wherein the grinding disc is arranged in the housing to divide the internal space of the housing into a grinding chamber and a discharge chamber; at least a part of the housing constitutes the grinding wall;

[0026] A water inlet pipeline, connected to the grinding chamber;

[0027] A discharge pipeline is arranged in communication with the discharge cavity.

[0028] Beneficial effects: The kitchen waste treatment equipment includes the anti-blocking structure of the present invention, so that the coil assembly can generate a magnetic field after being energized. Under the action of the magnetic field, the magnetic fluid moves along the annular channel between the grinding disc and the grinding wall to clean up blockages such as oil stains in the annular channel. The grinding disc does not need to be disassembled for cleaning, which improves the cleaning convenience and enhances the user experience; and it can be cleaned in time after blockage, which is not easy to cause damage and malfunction of the kitchen waste treatment equipment.

[0029] In a third aspect, the present invention further provides an anti-blocking control method, which is applicable to any of the anti-blocking structures or the kitchen waste treatment equipment described above, and the control method comprises:

[0030] Obtaining the blockage status in the annular passage between the grinding disc and the grinding wall;

[0031] If there is a blockage in the annular passage, the control coil is energized, and a magnetic field is generated between the grinding wall and the grinding disc;

[0032] The outlet of the magnetic fluid storage tank is controlled to open, and the magnetic fluid flows along the annular channel under the action of the magnetic field.

[0033] Beneficial effect: By obtaining the blockage status in the annular channel between the grinding disc and the grinding wall, the coil is energized in time when there is a blockage, and the outlet of the magnetic fluid storage tank is controlled to open. The magnetic fluid flows along the annular channel under the action of the magnetic field generated by the coil. The magnetic particles in the magnetic fluid act on the blockage, disintegrate the blockage, and discharge the blockage smoothly, avoiding equipment blockage and affecting the normal use of users.

[0034] In an optional embodiment, obtaining the blockage state in the annular channel between the grinding disc and the grinding wall includes:

[0035] Get the signal of the photoelectric sensor;

[0036] Determine whether there are any obstructions in the annular channel;

[0037] Alternatively, obtaining a capacitance value measured by a capacitance sensor;

[0038] Determine whether the capacitance value is equal to the capacitance value when there is no obstruction in the annular channel.

[0039] Beneficial effects: The photoelectric sensor includes a transmitting tube and a receiving tube, one of which can be set on the grinding wall and the other on the grinding disk. When there is a blockage, the light emitted by the transmitting tube is blocked, and the receiving tube cannot receive the light signal. At this time, it is determined that there is a blockage. The photoelectric sensor can quickly identify whether there is an obstruction in the annular channel; the capacitive sensor can detect the capacitance between the grinding wall and the grinding disk. When there is no oil, the capacitance value between the two is C0. If oil accumulates in the annular channel, the dielectric constant in the capacitor will change, causing the capacitance value between the two to change. At this time, the capacitance value C≠C0, which is determined to be an oil blockage. The capacitive sensor has high detection accuracy.

[0040] In an optional embodiment, after the outlet of the magnetic flow storage tank is controlled to be opened, the method further comprises:

[0041] Obtaining the blockage status in the annular passage between the grinding disc and the grinding wall;

[0042] If there is no obstruction in the annular passage, the control coil is powered off, and the outlet of the magnetic flow storage tank is controlled to be closed.

[0043] Beneficial effect: During the process of cleaning the blockage with magnetic fluid, the blockage status in the annular channel is continuously monitored. If the blockage has been cleared, the control coil is powered off, the outlet of the magnetic fluid storage tank is controlled to be closed, and the cleaning operation is stopped in time to save energy.

[0044] In an optional implementation, energizing the control coil includes:

[0045] Controlling the alternating current passing through the coil.

[0046] Beneficial effects: Controlling the alternating current passing through the coil to generate an alternating magnetic field, achieving the up and down reciprocating motion of the magnetic fluid, effectively improving the cleaning effect and cleaning efficiency, making full use of the magnetic fluid, and not causing waste of the magnetic fluid.

[0073] Combine the following Figures 1 to 9 , describing an embodiment of the present invention.

[0074] According to an embodiment of the present invention, on the one hand, an anti-blocking structure is provided, which is applicable to a garbage disposal device, wherein the garbage disposal device comprises a grinding wall 1 and a grinding disc 2, wherein an annular space channel 13 suitable for discharging grinding products is formed between the grinding disc 2 and the grinding wall 1; the anti-blocking structure comprises:

[0075] A coil assembly 5, arranged on the grinding wall 1 and / or the grinding disc 2;

[0076] A power source, electrically connected to the coil assembly 5, wherein the coil assembly 5 generates a magnetic field between the grinding wall 1 and the grinding disc 2 when powered on;

[0077] The magnetic flow mechanism comprises a magnetic flow storage tank 31 filled with magnetic fluid 4. After the outlet of the magnetic flow storage tank 31 is opened, the magnetic fluid 4 can flow along the annular channel 13 under the action of the magnetic field to clear the blockage in the annular channel 13.

[0078] A coil assembly 5 is arranged on the grinding wall 1 and / or the grinding disc 2. The coil assembly 5 can generate a magnetic field after being energized. Under the action of the magnetic field, the magnetic fluid 4 can move along the annular channel 13 between the grinding disc 2 and the grinding wall 1 to clean blockages such as oil stains in the annular channel 13. The grinding disc 2 does not need to be disassembled for cleaning, which improves the cleaning convenience and enhances the user experience.

[0079] In some embodiments, the coil assembly 5 comprises:

[0080] A first coil 51, embedded in the grinding wall 1;

[0081] and / or a second coil 52 , which is arranged on the peripheral side of the grinding disc 2 close to the grinding wall 1 .

[0082] The coil assembly 5 can be arranged on one of the grinding wall 1 and the grinding disk 2, with a simple structure; the first coil 51 can also be arranged in the grinding wall 1, and the second coil 52 can be arranged in the grinding disk 2. Such an arrangement can increase the magnetic field strength, the magnetic force acting on the magnetic fluid 4 is stronger, the dredging effect is better, and the cleaning efficiency can be effectively improved.

[0083] When both the first coil 51 and the second coil 52 are powered, both generate magnetic fields, and the directions of the magnetic fields generated by the two are consistent, which has a superposition and reinforcement effect. Alternatively, when one of the first coil 51 and the second coil 52 is powered, the unpowered coil can also generate a magnetic field due to mutual induction.

[0084] In some embodiments, Figure 2 As shown, a plurality of evenly distributed first coils 51 are provided on the grinding wall 1, and a second coil 52 is provided on the grinding disc 2. Since the grinding disc 2 rotates during the process of grinding garbage, only one coil is provided to act on the magnetic fluid 4 in a whole circle of the annular channel 13, and the structure is simplified. Of course, in other embodiments, a plurality of second coils 52 may also be provided on the grinding disc 2 to improve working reliability.

[0085] In some embodiments, the anti-blocking structure further includes a switching circuit for converting the positive and negative polarities of the power source, and the power source is disposed in the switching circuit.

[0086] The use of an exchange circuit facilitates the control and exchange of the polarity of the power supply, realizes the rapid conversion of the positive and negative poles of the power supply, and then can provide alternating current to the coil. The polarity of the magnetic field can be periodically changed, so that the magnetic fluid 4 can reciprocate up and down in the annular channel 13, quickly disintegrate the blockage, and effectively improve the cleaning effect and cleaning efficiency.

[0087] In some embodiments, the magnetic flow storage tank 31 is disposed above the annular channel 13 .

[0088] After the outlet of the magnetic fluid storage tank 31 is opened, the magnetic fluid 4 moves more smoothly to the annular channel 13 below it under the action of gravity, thereby increasing the movement speed of the magnetic fluid 4. Even if the coil is not passing through the electromagnetic fluid 4 at this time, the magnetic fluid 4 can smoothly reach the annular channel 13; and the gravity can also serve as a supplement to the magnetic field effect, overcoming the insufficient magnetic field strength caused by the distance limitation between the magnetic fluid storage tank 31 and the annular channel 13, and the magnetic fluid 4 can smoothly reach the annular channel 13.

[0089] In some embodiments, the magnetic flow mechanism further includes a collection chamber 32, and the magnetic fluid 4 is suitable for flowing into the collection chamber 32 under the action of gravity.

[0090] After the blockage is cleared, the magnetic fluid 4 flows into the lower collecting chamber 32 under the action of gravity, so that the magnetic fluid 4 can be recycled or collected for treatment.

[0091] In some embodiments, the anti-blocking structure further includes a photoelectric sensor or a capacitive sensor for determining a blockage state in the annular channel 13 .

[0092] The blocking state of the annular passage 13 is determined by a photoelectric sensor or a capacitive sensor. If there is a blockage, the controller 8 starts the coil of the anti-blocking structure to energize and open the outlet of the magnetic flow storage tank 31 for cleaning and dredging.

[0093] According to an embodiment of the present invention, on the other hand, Figure 1 As shown, a kitchen waste treatment device is also provided, comprising:

[0094] Grinding wall 1;

[0095] An annular channel 13 suitable for discharging the grinding product is formed between the grinding disc 2 and the grinding wall 1;

[0096] Anti-clogging structure;

[0097] A housing, wherein the grinding disc 2 is disposed in the housing to divide the internal space of the housing into a grinding chamber 11 and a discharge chamber 12; at least a portion of the housing constitutes the grinding wall 1;

[0098] A water inlet pipe 6 is connected to the grinding chamber 11;

[0099] The discharge pipeline 7 is connected to the discharge cavity 12 .

[0100] The kitchen waste disposal equipment includes the anti-blocking structure of the present invention, so that the coil assembly 5 can generate a magnetic field after being energized. Under the action of the magnetic field, the magnetic fluid 4 moves along the annular channel 13 between the grinding disc 2 and the grinding wall 1 to clean blockages such as oil stains in the annular channel 13. The grinding disc 2 does not need to be disassembled for cleaning, which improves the cleaning convenience and enhances the user experience; and it can be cleaned in time after blockage, which is not easy to cause damage and malfunction of the kitchen waste disposal equipment.

[0101] According to an embodiment of the present invention, on the other hand, Figure 3 As shown, an anti-blocking control method is also provided, which is applicable to the anti-blocking structure and the kitchen waste treatment equipment, and the control method includes:

[0102] Obtaining the blockage state in the annular passage 13 between the grinding disc 2 and the grinding wall 1;

[0103] If there is a blockage in the annular passage 13, the control coil is energized, and a magnetic field is generated between the grinding wall 1 and the grinding disc 2;

[0104] The outlet of the magnetic fluid storage tank 31 is controlled to be opened, and the magnetic fluid 4 flows along the annular channel 13 under the action of the magnetic field.

[0105] By obtaining the blockage status in the annular channel 13 between the grinding disc 2 and the grinding wall 1, the coil is energized in time when there is a blockage, and the outlet of the magnetic fluid storage tank 31 is controlled to open. The magnetic fluid 4 flows along the annular channel 13 under the action of the magnetic field generated by the coil, and the magnetic particles in the magnetic fluid 4 act on the blockage, disintegrate the blockage, and discharge the blockage smoothly, avoiding equipment blockage affecting normal use of users.

[0106] In some embodiments, Figure 4 and Figure 5 As shown, the obtaining of the blockage state in the annular channel 13 between the grinding disc 2 and the grinding wall 1 includes:

[0107] Get the signal of the photoelectric sensor;

[0108] Determine whether there is an obstruction in the annular channel 13;

[0109] Alternatively, obtaining a capacitance value measured by a capacitance sensor;

[0110] It is determined whether the capacitance value is equal to the capacitance value when there is no obstruction in the annular channel 13 .

[0111] The photoelectric sensor includes a transmitting tube and a receiving tube, one of which can be set on the grinding wall 1, and the other can be set on the grinding disc 2. When there is a blockage, the light emitted by the transmitting tube is blocked, and the receiving tube cannot receive the light signal. At this time, it is determined that there is a blockage. The photoelectric sensor can quickly identify whether there is an obstruction in the annular channel 13.

[0112] The capacitance sensor can detect the capacitance between the grinding wall 1 and the grinding disc 2. When there is no oil, the capacitance value between the two is C0. If oil accumulates in the annular channel 13, the dielectric constant in the capacitor will change, causing the capacitance value between the two to change. At this time, the capacitance value C≠C0, which means that there is oil blockage. The capacitance sensor has high detection accuracy.

[0113] In some embodiments, Figure 6 As shown, after the outlet of the magnetic flow storage tank 31 is controlled to be opened, the method further includes:

[0114] Obtaining the blockage state in the annular passage 13 between the grinding disc 2 and the grinding wall 1;

[0115] If there is no obstruction in the annular passage 13 , the control coil is powered off, and the outlet of the magnetic flow storage tank 31 is controlled to be closed.

[0116] During the process of cleaning the blockage with the magnetic fluid 4, the blockage state in the annular channel 13 is continuously monitored. If the blockage has been cleared, the control coil is powered off, the outlet of the magnetic fluid storage tank 31 is controlled to be closed, and the cleaning operation is stopped in time to save energy.

[0117] In some embodiments, Figure 7 As shown, the control coil is energized including:

[0118] Controlling the alternating current passing through the coil.

[0119] The alternating current passing through the coil is controlled to generate an alternating magnetic field, thereby realizing the up and down reciprocating motion of the magnetic fluid 4, effectively improving the cleaning effect and cleaning efficiency, making full use of the magnetic fluid 4, and not causing waste of the magnetic fluid 4.

[0120] When the kitchen garbage disposer starts working, the controller 8 detects that there is oil accumulation between the grinding disc 2 and the grinding wall 1. The controller 8 passes an alternating current through the coil assembly 5. The coil is located between the grinding disc 2 and the grinding chamber 11. The energized coil generates a magnetic field, and the magnetic field is located between the grinding disc 2 and the grinding chamber 11. The magnetic fluid 4 moves up and down in the magnetic field, and the magnetic particles in the magnetic fluid 4 clean the oil.

[0121] If the controller 8 detects that the oil sensor still has a signal after the operation is completed, it means that there is still oil between the grinding disc 2 and the grinding chamber 11. The magnetic particles in the magnetic fluid 4 continue to clean the oil, and the garbage debris and the cleaned oil are discharged from the discharge pipe 7. Until the controller 8 detects that the oil sensor has no signal, the controller 8 stops energizing the coil, and the magnetic fluid 4 flows down to the collection chamber 32, and the cleaning working mode is exited. The connection relationship between the controller 8 and the coil assembly 5 can be seen in Figure 8 , the connection structure between the controller 8 and the coil assembly 5, the motor 10 and the solenoid valve 9 is shown in Fig. 9 .
