[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] According to an embodiment of the present invention, a kitchen waste disposer is provided. Please refer to [link / reference]. Figures 1 to 6 The device includes: a housing 1, with a grinding chamber 2 inside the housing 1 containing a conductive medium, and a first capacitor 3 on the housing 1; a grinding disc 4, rotatably disposed inside the grinding chamber 2; a second capacitor 5 disposed inside the grinding disc 4, corresponding to the first capacitor 3; and a detection circuit connected to both the first capacitor 3 and the second capacitor 5; when the second capacitor 5 rotates to a preset position, the detection circuit detects the capacitance value between the first capacitor 3 and the second capacitor 5.

[0031] Specifically, the dielectric constant of the capacitance value between the first capacitor plate 3 and the second capacitor plate 5 is affected by the conductive medium between the capacitor plates. If there is no conductive medium between the first capacitor plate 3 and the second capacitor plate 5, the dielectric constant is the dielectric constant of air. At this time, the capacitance value when there is no garbage will be obtained. If there is a blockage caused by the accumulation of kitchen garbage between the two capacitor plates, the dielectric constant will change. At this time, a new capacitance value will be obtained, which is the capacitance value when there is a blockage. By judging whether the detected capacitance value is close to the capacitance value when there is a blockage, it is determined whether there is a blockage between the first capacitor plate 3 and the second capacitor plate 5.

[0032] It should be noted that during the grinding process of the grinding disc 4, the capacitance value feedback between the first capacitor 3 and the second capacitor 5 is obtained through the detection circuit to determine whether there is a blockage between the first capacitor 3 and the second capacitor 5. At the same time, the second capacitor 5 located on the grinding disc 4 rotates with the grinding disc 4. When it is determined that there is a blockage between the first capacitor 3 and the second capacitor 5, the location of the blockage can be obtained through the preset installation position of the first capacitor 3 or the second capacitor 5, thereby controlling the garbage disposal unit to clean in a targeted manner. This realizes the judgment of the blockage location of the kitchen garbage disposal unit, prevents the kitchen garbage disposal unit from becoming blocked, improves detection efficiency and accuracy, and solves the technical problem in related technologies where kitchen garbage disposal units are blocked and the location of the blockage cannot be detected.

[0033] In the kitchen waste disposer of this embodiment, see Figure 1The kitchen waste disposer includes a waste passage 11, which is located on the inner wall of the housing 1 and is connected to a drain pipe 6. The waste in the grinding chamber 2 passes through the waste passage 11 and enters the drain pipe 6.

[0034] Specifically, after being ground, the waste passes through the waste channel 11 and enters the drain pipe 6.

[0035] Specifically, the garbage passage 11 includes multiple garbage passage 11s, which are evenly distributed on the inner wall of the housing 1.

[0036] In the kitchen waste disposer of this embodiment, see Figure 1 The kitchen waste disposer includes: a water inlet pipe 7 connected to the grinding chamber 2, and a solenoid valve installed on the water inlet pipe 7; a cleaning device 8 disposed inside the grinding chamber 2 and connected to the solenoid valve; and a controller connected to a detection circuit, the solenoid valve, and the cleaning device 8 to control the cleaning device 8 to clean the grinding chamber 2 based on the capacitance value between the first capacitor 3 and the second capacitor 5. With the above configuration, when a blockage is detected between the first capacitor 3 and the second capacitor 5, the controller controls the solenoid valve and the cleaning device 8 to open, thereby allowing the cleaning device 8 to clean the grinding chamber 2.

[0037] In the kitchen waste disposer of this embodiment, see Figure 1 The cleaning device 8 is installed on the inner wall of the housing 1. The cleaning device 8 includes a nozzle 81, which is rotatably disposed. With the above arrangement, the nozzle 81 can be directed toward any position inside the grinding chamber 2, and can perform all-round cleaning of the inside of the grinding chamber 2.

[0038] In another embodiment of the kitchen waste disposer, see Figure 3 The cleaning device 8 includes a nozzle 81, which protrudes from the grinding disc 4 and is movable.

[0039] With the above settings, the cleaning device 8 can rotate together with the grinding disc 4. When the grinding disc rotates to the position of abnormal capacitance value, the controller can drive the cleaning device 8 to rinse in time.

[0040] Specifically, during grinding, the nozzle 81 can be hidden in the grinding disc. After grinding, the nozzle 81 rises along the rotation axis of the grinding disc to clean the grinding chamber 2.

[0041] In the kitchen waste disposer of this embodiment, see Figure 2 The first capacitor 3 includes multiple first capacitors 3, which are distributed at intervals around the axis of the grinding cavity 2 on the housing 1.

[0042] With the above settings, each first capacitor 3 can form a capacitance effect with the second capacitor 5. The location of the blockage can be determined based on the preset position of each first capacitor 3, so as to control the cleaning device 8 to clean the area.

[0043] It is understandable that, since the garbage passage 11 is frequently clogged, the first capacitor 3 can be placed inside the garbage passage 11 to improve the utilization efficiency of the capacitor. Alternatively, the first capacitor 3 can be placed on one side of the garbage passage 11 to achieve more comprehensive detection of blockages in the grinding chamber 2.

[0044] It is understandable that the number of second capacitor pieces 5 can be one or more.

[0045] In this embodiment, the second capacitor 5 is one piece. The position of the second capacitor 5 on the grinding disk 4 can be adjusted along the radial direction of the grinding disk 4. The specific position is not limited, but it is necessary to ensure that the second capacitor 5 is parallel to any one of the first capacitors 3.

[0046] In some embodiments, the first capacitor sheet 3 is arranged in a ring on the housing 1. By setting the capacitor sheet in a ring, more comprehensive detection of blockages in the grinding chamber can be achieved.

[0047] Specifically, when the above embodiment is used, the location of the blockage can be determined by recording the rotation angle of the second capacitor 5.

[0048] Specifically, the first capacitor 3 and the second capacitor 5 are both hidden in the structure and do not come into direct contact with the contents of the grinding chamber.

[0049] In the kitchen waste disposer of this embodiment, see Figure 5 The kitchen waste disposer includes: a cover plate 12, which is connected to the housing and is used to seal the grinding chamber 2; and a motor 9, which is driven by the grinding disc 4 to rotate the grinding disc 4 and is connected to the controller for signal transmission. The cover plate 12 is used to cover the grinding chamber 2, preventing waste from splashing out during grinding.

[0050] In the control method of this embodiment, see Figure 5 The control method is applicable to the above-mentioned kitchen waste disposer. The control method includes: obtaining the capacitance value between the first capacitor 3 and the second capacitor 5 through a detection circuit, and determining whether the first capacitor 3 and the second capacitor 5 are blocked based on the capacitance value; if the first capacitor 3 and the second capacitor 5 are blocked, then cleaning is performed; if the first capacitor 3 and the second capacitor 5 are not blocked, then no cleaning is performed.

[0051] Using the above control method, during the grinding process, the detection circuit detects the capacitance value between the first capacitor 3 and the second capacitor 5 to determine whether a blockage has occurred between the first capacitor 3 and the second capacitor 5, and obtains the location of the blockage. If a blockage occurs, the garbage disposal unit is controlled to clean it in time. This method can realize the functions of blockage handling and self-cleaning of the kitchen garbage disposal unit.

[0052] At the start of grinding, the second capacitor 5 is in its initial position, forming a capacitive effect with the first capacitor 3. The controller records the capacitance value obtained by the detection circuit. When the motor drives the second capacitor 5 to the relative position of the second capacitor 3, the controller re-records the capacitance value obtained by the detection circuit, and this process is repeated. As grinding continues, the waste is gradually ground into fragments and enters the drain pipe through the waste channel. At this time, every time the controller detects the capacitance value C, the dielectric constant between the first capacitor 3 and the second capacitor 5 changes due to the waste fragments, thus the trend of blockage can be judged based on the change in capacitance value.

[0053] In the control method of this embodiment, the method of obtaining the capacitance value between the first capacitor 3 and the second capacitor 5 through the detection circuit and determining whether there is a blockage between the first capacitor 3 and the second capacitor 5 based on the capacitance value includes: when the grinding disc 4 is turned on, obtaining the first capacitance value A between the first capacitor 3 and the second capacitor 5 through the detection circuit, and determining whether there is a blockage between the first capacitor 3 and the second capacitor 5 based on the first capacitance value A; when the grinding disc 4 is turned off, obtaining the second capacitance value B between the first capacitor 3 and the second capacitor 5 through the detection circuit, and determining whether there is a blockage between the first capacitor 3 and the second capacitor 5 based on the second capacitance value B.

[0054] It should be noted that when the product leaves the factory, the capacitance value between the first capacitor 3 and the second capacitor 5 when there is no debris will be recorded. When the detected capacitance value is within the first capacitance threshold range C1-C2, the detected capacitance value is close to the capacitance value when there is no debris. The capacitance value when completely blocked will also be recorded. When the detected capacitance value is within the second capacitance threshold range C3-C4, the detected capacitance value is close to the capacitance value when completely blocked.

[0055] Specifically, during grinding, a first capacitance value A is acquired, and the first capacitance value A is compared with a first capacitance threshold range to determine whether a blockage is about to occur in the grinding chamber. The blockage point that is about to occur is then treated to prevent blockage. After grinding, when cleaning the inside of the grinding chamber, a second capacitance value B is acquired, and the second capacitance value B is compared with a second capacitance threshold range to determine whether the cleaning is complete.

[0056] In the control method of this embodiment, when the grinding disc 4 is turned on, the first capacitance value A between the first capacitor 3 and the second capacitor 5 is obtained by the detection circuit. The method for determining whether there is a blockage between the first capacitor 3 and the second capacitor 5 based on the first capacitance value A includes: comparing the first capacitance value A with a first capacitance threshold range C1-C2; if A is within the first capacitance threshold range, it is determined that there is a blockage between the first capacitor 3 and the second capacitor 5; if A is not within the first capacitance threshold range, it is determined that there is no blockage between the first capacitor 3 and the second capacitor 5.

[0057] Specifically, during the grinding process, the first capacitance value A detected between the first capacitor 3 and any one of the second capacitors 5 is between the capacitance value when there is no garbage and the capacitance value when it is completely blocked. If A is within the first capacitance threshold range, it is determined that there is a lot of residual garbage here, and the first capacitance value A tends to approach the capacitance value when it is completely blocked, indicating that a blockage is about to occur. Then, the controller drives the cleaning device 8 to flush and prevent garbage fragments from accumulating and causing a blockage. If A is not within the first capacitance threshold range, it is determined that there is no need to clean between the first capacitor 3 and the second capacitor 5. This method plays a role in treating the blockage when the kitchen garbage disposal is about to become blocked.

[0058] In the control method of this embodiment, when the grinding disc 4 is turned off, the second capacitance value B between the first capacitor 3 and the second capacitor 5 is obtained by the detection circuit. The method for determining whether there is a blockage between the first capacitor 3 and the second capacitor 5 based on the second capacitance value B includes: comparing the second capacitance value B with a second capacitance threshold range C3-C4; if B is not within the second capacitance threshold range, it is determined that there is a blockage between the first capacitor 3 and the second capacitor 5; if B is within the second capacitance threshold range, it is determined that there is no blockage between the first capacitor 3 and the second capacitor 5.

[0059] Specifically, after the grinding process ends and the cleaning procedure is performed, the capacitance value should be close to the capacitance value when there is no garbage. The detection circuit obtains the second capacitance value B between the first capacitor 3 and any one of the second capacitors 5. The second capacitance value B is between the capacitance value when there is no garbage and the capacitance value when it is completely blocked. If B is not within the second capacitance threshold range, it is determined that there is a lot of residual garbage. The controller then drives the cleaning device 8 to rinse to prevent garbage residue from accumulating and producing odors. If A is within the second capacitance threshold range, it is determined that there is no need to clean between the first capacitor 3 and the second capacitor 5. This method serves to detect whether the kitchen garbage disposal unit has been completely cleaned after cleaning.

[0060] In the control method of this embodiment, the kitchen waste disposer includes a cleaning device 8, which is used to clean the grinding chamber 2. If there is blockage between the first capacitor plate 3 and the second capacitor plate 5, the cleaning method includes: when it is determined that there is blockage between the first capacitor plate 3 and the second capacitor plate 5, the cleaning device 8 is activated to clean the grinding chamber 2 until there is no longer blockage between the first capacitor plate 3 and the second capacitor plate 5. Through the above settings, the cleaning device 8 automatically cleans the blockage, realizing the functions of blockage handling and self-cleaning of the kitchen waste disposer.

[0061] In this embodiment, the control method detects the capacitance value between the first capacitor 3 and the second capacitor 5 during and after the grinding process. This can determine whether a blockage is about to occur in the grinding chamber and treat any potential blockages to prevent them from happening. This also prevents the kitchen waste disposer from becoming clogged. After grinding, the method checks whether cleaning is complete and detects any residual waste in the kitchen waste disposer to prevent it from causing odors. By controlling the cleaning device 8 to clean the blockages based on the blockage situation, the kitchen waste disposer achieves the functions of blockage treatment and self-cleaning.

[0062] The following is combined Figure 6 Here is an optional embodiment.

[0063] Specifically, the controller detects whether a blockage is about to occur by detecting the capacitance value between the capacitor plates of the grinding disc and the capacitor plate group of the grinding chamber, and drives the water pump to flush the location where a blockage is about to occur.

[0064] When the product leaves the factory, the capacitance value C1 between the grinding disc capacitor and the capacitor of each grinding chamber will be recorded, and the capacitance reference value C2 when completely blocked will be set.

[0065] At the start of grinding, the grinding disc capacitor is in its initial position, forming a capacitive effect with the first grinding chamber capacitor. The controller records the capacitance value C. When the motor drives the grinding disc capacitor to the relative position of the second grinding chamber capacitor, the controller records the capacitance value C again, repeating this process. As grinding continues, the waste is gradually ground into fragments and enters the drain pipe through the slot. Each time the controller detects the capacitance value C, the dielectric constant between the grinding disc capacitor and the grinding chamber capacitor changes due to the waste fragments, causing the detected capacitance value C to tend towards the reference capacitance value C2 when completely blocked. When the controller detects that the capacitance value C is close to the reference capacitance value C2, it drives a water pump to flush the corresponding grinding chamber capacitor to prevent the accumulation of waste fragments and subsequent blockage.

[0066] After grinding is completed, the controller drives the motor to rotate and detects the capacitance value C between the grinding disc capacitor and the grinding chamber capacitor group again. At this time, the capacitance value C should be close to C1 when there is no waste. If the controller detects that it is not close to C1, it means that there is a lot of waste residue at the grinding chamber capacitor. The controller drives the water pump to flush this area to prevent the waste residue from producing odor.

[0067] The kitchen waste disposer in this embodiment can achieve blockage removal and self-cleaning functions through this method; it can prevent blockage and detect residual waste through a capacitance detection method; the shape and number of the capacitor plate group in the grinding chamber and the capacitor plate in the grinding disc are not specific requirements, as long as the capacitance value between the slots can be detected, and the specifics are determined by the product.
