Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, specifically to a waste treatment device and a waste treatment method. Background Technology

[0002] Currently, garbage disposals are becoming increasingly popular among users, especially food waste disposers, which are gradually becoming an indispensable appliance in the kitchen. A food waste disposer uses a grinding motor to drive a grinding disc at high speed, causing the blades on the disc to collide, strike, cut, and grind the garbage thrown into the disposal chamber, reducing the size of the food waste so it can be discharged through the drain pipe.

[0003] Existing garbage disposers grind up kitchen waste and then flush the ground waste into the drain pipe by controlling the flushing mechanism to introduce water into the garbage disposal chamber. However, some larger or stickier pieces of waste inevitably remain in the ground waste and accumulate in the drain pipe, making them difficult to flush away. This increases the risk of drain pipe blockage and shortens the service life of the disposer. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of high risk of blockage and short service life of the drain pipe of the garbage disposal unit in the prior art, so as to provide a garbage disposal equipment and garbage disposal method that can effectively monitor the drain pipe, reduce the risk of blockage, extend the service life of the drain pipe, and at the same time save water resources.

[0008] Optionally, after adjusting the flushing water flow of the flushing procedure based on the difference between the current turbidity value and the first preset threshold, the following steps are further performed: after the second preset flushing time is reached, the steps of detecting the current turbidity value and flushing the waste treatment chamber are repeated until the absolute value of the difference between the current turbidity value and the first preset threshold is detected to be less than the second preset difference for n consecutive times, at which point the flushing procedure is stopped; where n≥3.

[0009] Optionally, if the absolute value of the difference between the current turbidity value and the first preset threshold is less than the second preset difference in n consecutive tests, after stopping the rinsing procedure, the following steps are performed: updating the first preset threshold to the last detected current turbidity value.

[0010] Optionally, if it is determined that the first preset threshold for pre-updating is greater than the second preset threshold, an abnormal prompt message is sent to the user to replace or manually clean the drain pipe, wherein the second preset threshold is the limit threshold when the drain pipe is blocked.

[0011] Optionally, the waste treatment equipment includes a flushing mechanism, the outlet of which is connected to the waste treatment chamber; adjusting the flushing water flow of the flushing procedure includes: adjusting the flow rate of the flushing water flow by adjusting the size of the outlet of the flushing mechanism, and / or adjusting the force of the sprayed water flow by adjusting the working power of the flushing mechanism.

[0012] Optionally, when the ground kitchen waste in the waste disposal chamber is started to be rinsed, the water outlet of the rinsing mechanism is opened to the maximum value to rinse the waste in the waste disposal chamber.

[0013] Optionally, adjusting the flushing water flow of the flushing procedure based on the difference between the current turbidity value and the first preset threshold includes: determining whether the absolute value of the difference between the current turbidity value and the first preset threshold is greater than the first preset difference; if yes, adjusting the outlet of the flushing mechanism to the first opening area; if no, further determining whether the absolute value of the difference between the current turbidity value and the first preset threshold is greater than the second preset difference, wherein the second preset difference is less than the first preset difference; if yes, adjusting the outlet of the flushing mechanism to the second opening area; if no, adjusting the outlet of the flushing mechanism to the third opening area; wherein the first opening area < the second opening area < the third opening area.

[0014] Optionally, the grinding process includes: after the waste is placed into the waste treatment chamber, controlling the injection of a set amount of water into the waste treatment chamber and controlling the grinding motor to start wet grinding of the waste; when the speed of the grinding motor is detected to be constant, it can be determined that grinding is completed and the grinding motor is controlled to stop working; controlling the drain valve at the bottom of the waste treatment chamber to open.

[0015] In a second aspect, the present invention provides a waste treatment device, comprising: a waste treatment chamber, a drain pipe, a flushing mechanism, a turbidity detection mechanism, and a controller; a drain outlet is provided at the bottom of the waste treatment chamber; the drain pipe is connected to the drain outlet; a grinding mechanism is disposed inside the waste treatment chamber and is adapted to grind the waste inside the waste treatment chamber; the flushing mechanism has its outlet connected to the waste treatment chamber and is adapted to introduce water into the waste treatment chamber; the turbidity detection mechanism is disposed in the drain pipe and is used to detect the turbidity information of the fluid inside the drain pipe; the controller is connected to the grinding mechanism, the flushing mechanism and the turbidity detection mechanism respectively, and is used to control the waste treatment device to treat waste using the above-mentioned waste treatment method.

[0016] Optionally, the device also includes a waste treatment control unit, which comprises a control module, an acquisition module, and a judgment module. The control module controls the waste treatment equipment to sequentially execute a grinding program and a rinsing program. The acquisition module acquires the current turbidity value of the fluid in the drain pipe of the waste treatment equipment after the waste treatment equipment has executed the rinsing program for a first preset rinsing time. The judgment module determines whether the current turbidity value is less than a first preset threshold. If so, the rinsing program is stopped; if not, the rinsing program continues to be executed, and the rinsing water flow of the rinsing program is adjusted based on the difference between the current turbidity value and the first preset threshold.

[0020] The present invention has the following advantages:

[0021] The waste disposal method provided by this invention, after grinding the waste in the waste disposal chamber, begins rinsing. After rinsing for a certain period, it monitors the current turbidity value of the fluid in the drain pipe and adaptively adjusts the rinsing water flow based on the difference between the current turbidity value and a first preset threshold. For example, if the difference between the detected current turbidity value and the first preset threshold is greater than a preset difference, it can be inferred that there is still a significant amount of residual waste in the drain pipe. In this case, the water flow rate can be increased to enhance the flushing force, thus fully utilizing the kitchen waste in the waste disposal chamber and drain pipe, making rinsing more efficient and thorough, reducing the risk of drain pipe blockage, and extending the service life of the drain pipe. If the difference between the detected current turbidity value and the first preset threshold is less than a preset difference, the water flow rate is reduced. This not only avoids water waste but also effectively mitigates the impact damage to the drain pipe caused by the long-term action of high-speed, high-pressure water flow, improving the stress performance of the pipe and its connections, and extending its service life. Therefore, it can effectively solve the problems of high risk of blockage and short service life of existing waste treatment equipment's drain pipes. Attached Figure Description

[0036] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] Example 1

[0038] like Figures 1 to 3As shown, this embodiment provides a waste treatment method for a waste treatment device. The waste treatment device 1 has a waste treatment chamber 10, and a grinding mechanism 15 for grinding kitchen waste is provided in the waste treatment chamber 10. The waste treatment device 1 also includes a flushing mechanism 13 that allows water to enter the waste treatment chamber 10 from below to flush the ground waste out from the drain pipe 11.

[0039] Combination Figure 1 and Figure 2 As shown, the waste treatment method provided in this embodiment includes: controlling the waste treatment equipment to sequentially execute a grinding program and a rinsing program; after the waste treatment equipment executes the rinsing program for a first preset rinsing time, obtaining the current turbidity value of the fluid in the drain pipe 11 of the waste treatment equipment; determining whether the current turbidity value is less than a first preset threshold; if so, stopping the rinsing program; if not, continuing to execute the rinsing program, and adjusting the rinsing water flow of the rinsing program based on the difference between the current turbidity value and the first preset threshold.

[0040] The kitchen waste treatment method provided in this embodiment starts rinsing after the waste in the waste treatment chamber is ground up. After rinsing for a certain period of time, the current turbidity value of the fluid in the drain pipe is monitored. The rinsing water flow of the rinsing program is adaptively adjusted according to the difference between the current turbidity value and the first preset threshold. This enables the full utilization of kitchen waste in the waste treatment chamber and drain pipe, reduces the risk of drain pipe blockage, extends the service life of the drain pipe, and also saves water resources.

[0041] For example, when it is determined that the difference between the currently detected turbidity value and the first preset threshold is greater than a preset difference, it can be inferred that there is still a significant amount of residual waste in the drain pipe. In this case, the water flow rate can be increased to enhance the flushing force, effectively targeting the kitchen waste in the waste disposal chamber and drain pipe, resulting in more efficient and thorough flushing, reducing the risk of drain pipe blockage, and extending the drain pipe's lifespan. When it is determined that the difference between the currently detected turbidity value and the first preset threshold is less than a preset difference, the water flow rate is reduced. This not only avoids water waste but also effectively mitigates the long-term impact damage to the drain pipe caused by high-speed, high-pressure water flow, improving the stress performance of the pipe and its connections, and extending its service life. Therefore, this effectively solves the problems of high risk of blockage and short service life of existing waste disposal equipment's drain pipes.

[0042] In this embodiment, the waste treatment equipment is a kitchen waste treatment equipment, and the waste treatment method is a kitchen waste treatment method.

[0043] In one embodiment of this invention, when it is determined that the difference between the currently detected turbidity value and the first preset threshold is greater than a preset difference, it can be inferred that there is still a significant amount of residual garbage in the drain pipe 11. At this point, the water flow rate can be increased to enhance the flushing force, thus fully utilizing the kitchen waste in the garbage disposal chamber 10 and the drain pipe 11. This makes flushing more efficient and thorough, reduces the risk of blockage in the drain pipe 11, and extends its service life. When it is determined that the difference between the currently detected turbidity value and the first preset threshold is less than a preset difference, the water flow rate is reduced. This not only avoids water waste but also effectively mitigates the impact damage to the drain pipe 11 caused by the long-term action of high-speed, high-pressure water flow, improving the stress performance of the pipe and its connections, and increasing its service life. This effectively solves the problem that the existing flushing mechanism 13 has a constant flushing water flow rate, which cannot fully utilize the garbage in the drain pipe 11, resulting in a high risk of blockage and a short service life for the drain pipe 11.

[0044] In one embodiment of this example, adjusting the flushing water flow in the flushing program includes: adjusting the flow rate of the flushing water flow in the flushing program. Adjusting the flushing water flow in the flushing program based on the difference between the current turbidity value and a first preset threshold includes the following steps: determining whether the absolute value of the difference between the current turbidity value and the first preset threshold is greater than a preset difference; if yes, then adjusting the flow rate of the flushing water flow to a first flow rate; if no, then adjusting the flow rate of the flushing water flow to a second flow rate, wherein the first flow rate > the second flow rate.

[0045] In another embodiment of this example, combined with Figure 1 and Figure 3 As shown, adjusting the flushing water flow of the flushing program based on the difference between the current turbidity value and a first preset threshold includes the following steps:

[0046] Determine whether the absolute value of the difference between the current turbidity value and the first preset threshold is greater than the first preset difference: if yes, adjust the flow rate of the flushing water to the first flow rate; if no, further determine whether the absolute value of the difference between the current turbidity value and the first preset threshold is greater than the second preset difference, wherein the second preset difference is less than the first preset difference: if yes, adjust the flow rate of the flushing water to the second flow rate; if no, adjust the flow rate of the flushing water to the third flow rate; wherein the first flow rate > the second flow rate > the third flow rate.

[0047] In the above embodiment, the difference between the current turbidity value T and the first preset threshold T1 is set to Δt, the first preset difference is ΔT1, the second preset difference is ΔT2, the first flow rate is V1, the second flow rate is V2, and the third flow rate is V3.

[0048] Table 1: Correspondence between Δt and the flow velocity of the flushing water

[0049] Difference Δt (ΔT1>ΔT2) The flow velocity of the water (V1 > V2 > V3) Δt>ΔT1 V1 ΔT2<Δt≤ΔT1 V2 Δt≤ΔT2 V3

[0050] Referring to Table 1, when the difference Δt between the current turbidity value T and the first preset threshold T1 is determined to be at a high level (greater than the first preset difference ΔT1), it indicates that the water flowing through the drain pipe 11 contains a large amount of kitchen waste. In this case, the flushing water flow is controlled at a high level with a first flow rate V1 to flush the waste disposal chamber 10 and the drain pipe 11, quickly flushing out the accumulated waste and reducing the risk of blockage. When the difference Δt between the current turbidity value T and the first preset threshold T1 is determined to be at a medium level (between the first preset difference ΔT1 and the second preset difference ΔT2), it indicates that the water flowing through the drain pipe 11 contains a small amount of kitchen waste. In this case, the flushing water flow is controlled at a medium level with a second flow rate V2 to flush the waste disposal chamber 10 and the drain pipe 11, effectively ensuring the flushing of residual waste while also conserving water resources. When it is determined that the difference Δt between the current turbidity value T and the first preset threshold T1 is at a low level, i.e. less than or equal to the second preset difference ΔT2, it indicates that the water flowing through the drain pipe 11 contains very little kitchen waste. At this time, the flushing water flow is controlled to flush the waste disposal chamber 10 and the drain pipe 11 at a low level of the third flow rate V3, so as to avoid water waste and also reduce the impact damage to the pipeline caused by the long-term action of high-speed and high-pressure water flow on the drain pipe 11.

[0051] In a preferred embodiment of this example, after adjusting the flushing water flow of the flushing procedure based on the difference between the current turbidity value and a first preset threshold, the following steps are further performed:

[0052] After the second preset flushing time is reached, the steps of detecting the current turbidity value and flushing the waste treatment chamber 10 are repeated until the absolute value of the difference between the current turbidity value and the first preset threshold is less than the second preset difference is detected n times in a row. Then the flushing program is stopped, where n≥3.

[0053] In the above embodiment, after adjusting the flow rate of the flushing water and flushing the waste treatment chamber 10 and the drain pipe 11 for a second preset time, the detection and flushing operation is repeated. If Δt is found to be less than ΔT2 for n consecutive times, the drain pipe 11 is considered clean and the flushing is considered complete, and the flushing process is stopped. For example, if Δt is found to be less than ΔT2 for 3, 4, or 5 consecutive times, it can be determined that the drain pipe 11 is clean, avoiding false judgments.

[0054] In a preferred embodiment of this example, after the rinsing procedure is stopped when the absolute value of the difference between the current turbidity value and the first preset threshold is less than the second preset difference for n consecutive times, the following steps are performed:

[0055] Update the first preset threshold to the current turbidity value detected last time.

[0056] After long-term use, some stubborn dirt and grime will accumulate on the wall of the drain pipe 11, which may cause the turbidity value detected the next time to be larger than the turbidity value detected the first time. Therefore, it is impossible to accurately determine the turbidity value of the fluid in the drain pipe 11. So, after each use, the current turbidity value detected the last time is replaced with the first preset threshold for the next initial judgment.

[0057] Furthermore, if it is determined that the first preset threshold for pre-updating is greater than the second preset threshold, an abnormal prompt message is sent to the user to replace or manually clean the drain pipe 11, wherein the second preset threshold is the limit threshold when the drain pipe 11 is blocked.

[0058] In the above scheme, the second preset threshold T2 represents extremely poor water quality in drain pipe 11, requiring users to be reminded to check and replace it promptly. Under normal circumstances, the first preset threshold T1 is less than the second preset threshold T2. However, after repeated use, impurities gradually accumulate in drain pipe 11, potentially leading to blockage. In this case, the pre-updated first preset threshold T1 will exceed the second preset threshold T2, requiring a notification to the user to clean or replace drain pipe 11 promptly to avoid related safety accidents.

[0059] For example, an alarm prompt can be issued to the user via voice and / or text and / or flashing lights so that the user can replace the drain pipe 11 in a timely manner.

[0060] In this embodiment, the waste treatment equipment 1 includes a rinsing mechanism 13. The outlet of the rinsing mechanism 13 is connected to the waste treatment chamber 10. The rinsing mechanism 13 is adapted to introduce water into the waste treatment chamber 10, wet the kitchen waste, and rinse the ground waste.

[0061] In some embodiments, adjusting the flushing water flow of the flushing procedure includes: adjusting the flow rate of the flushing water flow by adjusting the size of the outlet of the flushing mechanism 13; and / or adjusting the force of the sprayed water flow by adjusting the operating power of the flushing mechanism 13.

[0062] For example, the rinsing mechanism 13 includes a housing and a water pump disposed within the housing. The housing has an outlet with an adjustable opening size. The outlet of the rinsing mechanism 13 is similar to the outlet of a high-pressure water gun for car washing. The speed of the water jet can be changed by changing the size of the outlet. The smaller the opening of the outlet, the higher the water speed. Alternatively, the water speed can be increased by increasing the working power of the water pump while keeping the opening constant, thereby increasing the water pressure.

[0063] Optionally, the process of rinsing the ground kitchen waste in the waste disposal chamber 10 includes: controlling the water outlet of the rinsing mechanism 13 to open to the maximum value to rinse the waste in the waste disposal chamber 10. Since the waste in the waste disposal chamber 10 is still relatively large after grinding, the water output of the rinsing mechanism 13 is relatively large at this time, which can improve the rinsing efficiency.

[0064] Preferably, in this embodiment, the speed of water jet is changed by changing the size of the outlet opening. Changing the size of the outlet is easier and more convenient than adjusting the working power of the water pump.

[0065] Specifically, in combination Figure 3 The flushing water flow adjustment procedure based on the difference between the current turbidity value and the first preset threshold, as shown in Table 2, includes: determining whether the absolute value Δt of the difference between the current turbidity value T and the first preset threshold T1 is greater than the first preset difference ΔT1; if yes, the outlet of the flushing mechanism 13 is adjusted to the first opening area D1, at which point the water flow velocity is at its maximum and at a high level, effectively flushing away the kitchen waste accumulated in the drain pipe 11; if no, it is further determined whether the absolute value Δt of the difference between the current turbidity value T and the first preset threshold T1 is greater than the second preset difference ΔT2, wherein the second preset difference ΔT2 is less than the first preset difference ΔT1; if yes, the outlet of the flushing mechanism 13 is adjusted to the second opening area D2, at which point the water flow velocity is at a medium level; if no, the outlet of the flushing mechanism 13 is adjusted to the third opening area D3, at which point the water flow velocity is at a low level, avoiding water waste; wherein the first opening area D1 < the second opening area D2 < the third opening area D3.

[0066] Table 2: Correspondence between Δt and outlet size

[0067] The difference Δt (ΔT1>ΔT2) The size of the water outlet D (D3>D2>D1) Δt>ΔT1 D1 ΔT2<Δt≤ΔT1 D2 Δt≤ΔT2 D3

[0068] Optionally, the grinding process includes: placing the kitchen waste to be processed into the waste processing chamber 10; then injecting a set amount of water into the waste processing chamber 10, controlling the grinding motor 151 to start wet grinding of the waste, and the waste can be wetted by injecting a set amount of water, which facilitates grinding and crushing; when the rotation speed of the grinding motor 151 is detected to be constant, it can be determined that the grinding is completed, and the grinding motor 151 is controlled to stop working.

[0069] During the grinding process, when the waste in the waste treatment chamber 10 is ground into a slurry solution, the drive load of the grinding motor 151 is constant, and the input power of the motor remains unchanged. The constant operating speed of the motor indicates that grinding is complete, and the grinding motor 151 can stop grinding. After grinding is completed, the drain valve 12 at the bottom of the waste treatment chamber 10 is opened to initiate the flushing process.

[0070] It should be noted that the waste treatment equipment described in this embodiment includes, but is not limited to, kitchen waste treatment equipment.

[0071] Example 2

[0072] like Figure 1 As shown, this embodiment provides a waste treatment device 1, which processes kitchen waste using any of the waste treatment methods described in Embodiment 1 above. The waste treatment device 1 includes: a waste treatment chamber 10, a drain pipe 11, a flushing mechanism 13, a turbidity detection mechanism 14, and a controller. The waste treatment chamber 10 has a drain outlet at its bottom; the drain pipe 11 is connected to the drain outlet. A grinding mechanism 15 is disposed inside the waste treatment chamber 10 and is suitable for grinding the waste inside the waste treatment chamber 10. The outlet of the flushing mechanism 13 is connected to the waste treatment chamber 10 and is suitable for introducing water into the waste treatment chamber 10. The turbidity detection mechanism 14 is disposed on the drain pipe 11 and is used to detect the turbidity information of the fluid inside the drain pipe 11. The controller is connected to the grinding mechanism, the flushing mechanism, and the turbidity detection mechanism respectively, and is used to control the waste treatment device to process waste using any of the waste treatment methods described in Embodiment 1 above.

[0073] In the above scheme, the main body of the waste treatment device is installed between the water tank 2 and the drain pipe 11. The waste treatment chamber 10 is provided with a waste inlet for connection with the water tank 2. The drain pipe 11 can be connected to the sewage outlet through a connector or drain pipe. After the kitchen waste enters the waste treatment chamber 10 through the water tank 2, the grinding mechanism 15 grinds the kitchen waste. After the kitchen waste is crushed and ground, it is discharged into the drain pipe 11. After the flushing mechanism 13 flushes for a certain period of time, the turbidity detection mechanism 14 is activated. The turbidity detection mechanism 14 starts to detect the turbidity value of the fluid flowing through the drain pipe 11 and feeds it back to the control unit of the waste treatment device. The control unit then adjusts the flow rate of the flushing water according to the difference between the current turbidity value and the first preset threshold, so as to achieve efficient removal of the accumulated waste, save water resources, and extend the service life of the drain pipe 11.

[0074] Furthermore, the waste treatment equipment also includes a waste treatment control device, which comprises a control module, an acquisition module, and a judgment module. The control module, including a controller, controls the waste treatment equipment to sequentially execute a grinding program and a rinsing program. The acquisition module acquires the current turbidity value of the fluid in the waste treatment equipment's drain pipe after the waste treatment equipment has executed the rinsing program for a first preset rinsing time. The judgment module determines whether the current turbidity value is less than a first preset threshold. If so, the rinsing program is stopped; otherwise, the rinsing program continues, and the rinsing water flow is adjusted based on the difference between the current turbidity value and the first preset threshold.

[0075] Furthermore, the waste treatment equipment also includes a computer-readable storage medium storing computer instructions for causing the waste treatment equipment to perform the waste treatment method according to any of the embodiments in Example 1 above.

[0076] In some embodiments, a flushing mechanism 13 is installed on top of the waste disposal chamber 10. The flushing mechanism 13 includes a housing and a water pump disposed within the housing. The housing has an outlet with an adjustable opening size. Water flows from top to bottom to flush the waste disposal chamber 10. Optionally, a rotating nozzle can be installed at the outlet to achieve thorough flushing of the waste disposal chamber 10 without dead angles. By adding a flushing mechanism 13 above the waste disposal chamber 10, water flows of different velocities can be sprayed to flush the waste disposal chamber 10 and the drain pipe 11. This solves the problem of flushing debris from the drain pipe 11. The grinding mechanism 15 includes a grinding motor 151 and a grinding disc 152 disposed at the output end of the grinding motor 151. The turbidity detection mechanism 14 is installed on the drain pipe 11 with its detection end located inside the drain pipe 11. Exemplarily, the turbidity detection mechanism 14 can be a water quality sensor, conductivity sensor, ORP sensor, etc. The turbidity detection mechanism 14 can provide a numerical value for the detected turbidity of the water.

[0077] Preferably, the drain pipe 11 includes a U-shaped pipe disposed below the waste treatment equipment, and the turbidity detection mechanism 14 is disposed on the U-shaped pipe of the drain pipe 11. By adding the turbidity detection mechanism 14 to the U-shaped pipe of the drain pipe 11, the turbidity value of the water stored in the U-shape is detected, thereby realizing the dynamic detection of the state of the drain pipe 11.

[0078] More preferably, the drain pipe 11 includes an upward-opening U-shaped section. The U-shaped design allows for a buffering process in the drainage, reducing pressure on the lower pipes and preventing odors from backing out of the drain pipe 11. More preferably, in this embodiment, the drain pipe 11 also includes an inverted U-shaped section. One end of the U-shaped section is connected to the drain outlet, and the other end is connected to the inlet of the inverted U-shaped section. The U-shaped and inverted U-shaped sections can be connected to each other or integrally injection molded to form a horizontal "S"-shaped section, which can further prevent odors from backing out of the drain pipe 11.

[0079] Furthermore, the turbidity detection mechanism 14 is a water quality sensor installed on the drain pipe 11. It is located near the bottom of the section.

[0080] Optionally, the waste treatment equipment 1 also includes a display screen, which is connected to a controller. The controller is connected to the grinding mechanism 15, the rinsing mechanism 13, and the turbidity detection mechanism 14, and is used to control the opening, closing, and operation of these components. The display screen shows the operating status of the waste treatment equipment 1, including grinding status, cleaning status, and abnormality alert status. The abnormality alert status includes a clogged drain pipe 11, prompting the user to replace or manually clean the drain pipe 11. For example, if the first preset threshold for pre-updating is determined to be greater than a second preset threshold, the display screen can display an abnormality alert via text or graphics. The display screen can also provide a user interface for human-machine interaction. Preferably, the controller and display screen are integrated into one unit.

[0081] In this embodiment, the waste disposal control device 16 is the core of operation and control. The controller has a built-in chip for data storage and logic control, sending relevant instructions to the corresponding execution devices and displaying relevant status feedback on the display screen, while also providing a user interface. The turbidity detection mechanism 14 mainly detects the turbidity information of the water stored in the U-shaped pipe of the drain pipe 11, thereby determining the state of the drain pipe 11 and whether there are any impurities in the water. The grinding mechanism 15 is mainly driven by a motor to rotate the grinding disc 152 at high speed, causing the waste put into the waste disposal chamber 10 to collide, knock, cut, and grind against the components on the grinding disc 152, reducing the size of the kitchen waste and ensuring that it can be discharged into the sewer through the drain pipe 11. A valve 12, which can be electrically or manually controlled, is installed at the drain outlet below the waste disposal chamber 10 to ensure that the water added during crushing does not flow away. The flushing mechanism 13 includes a water pump and a water outlet. The water pump provides water flow, and the opening area of ​​the water outlet can be controlled by the waste disposal control device 16 to provide different water velocities, thereby solving the problems of easy blockage of the drain pipe 11 and short service life of the pipe in the prior art.

[0082] The working process of the waste treatment equipment 1 provided in this embodiment is as follows:

[0083] Users can turn the waste disposal equipment 1 on or off via the waste disposal control device 16. After the user pours the waste to be ground into the waste disposal chamber 10, the waste disposal equipment 1 is turned on. The flushing mechanism 13 adds a certain amount of water to the waste disposal chamber 10, and the grinding motor 151 starts working to grind the kitchen waste. When the rotational speed of the grinding motor 151 is constant, the grinding is considered complete, and the grinding mechanism 15 stops working. Then, the drain valve 12 is opened, and the outlet of the flushing mechanism 13 is opened to its maximum to flush the waste disposal chamber 10 for a certain period of time (e.g., 5 seconds, 10 seconds). After flushing, the turbidity detection mechanism 14 measures the turbidity value T of the water in the U-shaped tube. The turbidity value T is compared with the set first preset threshold T1. If it is less than T, the pipe flushing is complete; if it is greater than or equal to T, the difference Δt between T and T1 is calculated, and the corresponding water flow rate is selected according to the magnitude of the difference Δt and the first preset threshold ΔT1 to flush the garbage treatment chamber 10 and the drain pipe 11 for a certain period of time (e.g., 5s or 10s). After flushing, the detection and flushing operation is repeated. If Δt is less than the second preset difference ΔT2 for n consecutive (3 or 5) times, it is determined that flushing is complete, and the set first preset threshold T1 is updated to the last detected turbidity value T. When the set first preset threshold T1 is greater than the set second preset threshold T2, a prompt to replace the drain pipe is displayed on the screen.

[0084] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
