Description

Food waste disposing device {APPARATUS FOR DISPOSING FOOD WASTE}

The present invention relates to an apparatus for processing food waste, and more specifically, first or firstly and secondly finely pulverizing food waste discharged from a sink, such as at home or a restaurant, decomposing it by introducing microorganisms, and then disassembling the sewage system. It relates to a food waste treatment system that treats sewage through

Food waste, which is an organic waste, is discharged in large quantities from general households and restaurants. Such food waste cannot be incinerated because it contains a large amount of moisture, and it is difficult to collect because of its large weight. Even if incineration treatment is possible, a lot of fuel is consumed, so it is not economical, and it is difficult to completely burn it. In addition, when incinerated, a large amount of pollutants such as dioxins, known to have a fatal effect on the human body, are emitted. In the case of landfilling food waste, most of it is bulky, which causes the number of years of use of the landfill to be rapidly reduced, and a large amount of leachate is generated, which causes severe odor and causes soil and water pollution.

On the other hand, technologies for collecting food waste and processing it into livestock feed or compost are being actively proposed, but it is difficult to collect and process it due to the large amount of water. In addition, food waste is stored for a certain period of time until it is collected at the food waste discharging site. In this process, the food waste decays or is not completely sealed, causing a bad odor and becoming a hotbed for mold and bacteria, and careless handling at the time of collection. As a result, food waste flows into the surrounding area and adversely affects the living environment.

1 is a diagram schematically illustrating an apparatus for treating food waste according to an embodiment.

The food waste treatment apparatus 100 includes a primary processing apparatus 200 , a secondary processing apparatus 1100 , a connection unit 1600 connecting the primary processing apparatus 200 and the secondary processing apparatus 1100 , and processed food. It may include a discharge pipe 2200 for discharging garbage.

The primary processing device 200 may be installed, for example, in a sink (not shown). In this case, the primary processing device 200 may be coupled to some components of the sink. In this case, a separate drain container (not shown) may be connected to the drain port (not shown) of the sink. In addition, it is also possible that the primary processing device 200 is directly connected. In this case, the primary treatment device 200 may include a function of a drain container. The primary treatment device 200 may physically pulverize the food waste using the blade unit. That is, the food waste can be pulverized on the spot by directly putting the food waste in the sink and operating the primary treatment device 200 . In addition, since water is fed through the sink, it is possible to efficiently pulverize it without a separate water inlet. The food waste pulverized in the primary treatment device 200 may be discharged to the secondary treatment device 1100 through the connection unit 1600 . The secondary treatment device 1100 may decompose the food waste by introducing a microorganism or a microbial culture solution to the firstly pulverized food waste and stirring it. The food waste decomposed in the secondary treatment device 1100 may be discharged to the sewage through the discharge pipe 2200 . In this way, food waste can be effectively treated through physical pulverization through the primary treatment device 200 and chemical decomposition through the secondary treatment device 1100 .

2 is a view showing the primary processing apparatus 200 in more detail.

The primary treatment device 200 may include a fixing unit 300 that may be installed in the drain port of the sink. The fixing unit 300 may be installed in the drain port when the sink is manufactured, or may be installed in the drain hole after the sink is manufactured. The inside of the fixing part 300 may be formed to penetrate, and water and food waste flowing into the drain may be introduced. The bottom surface of the fixing part 300 may be inclined. In this case, food waste and water can be safely and accurately guided to the grinding housing 280 through the lower surface of the fixing unit 300 . A locking plate (not shown) may be disposed on the upper surface of the fixing part. The locking plate may have wings that are separated from each other. At this time, the wing unit may allow food waste and water to enter the inside of the fixing unit 300 in an appropriate amount. In addition, the wing unit may block food waste and odors rising from the fixing unit 300 and the grinding housing 280 .

The cover 210 may be selectively coupled to the fixing part 300 . At this time, the cover 210 may be coupled to the portion of the fixing part 300 exposed through the drain hole of the sink to block the fixing part 300 . At this time, the cover 210 may be fixed to the fixing unit 300 in various ways. For example, the cover 210 may be fixed by rotating the fixing unit 300 . As another embodiment, the cover 210 may be fixed by simply fitting it to the fixing unit 300 . Hereinafter, for convenience of description, a case in which the cover 210 is fixed by rotating on the fixing unit 300 will be mainly described.

One of the cover 210 or the fixing part 300 may include a coupling protrusion protruding from the outer surface. In addition, the other one of the cover 210 or the fixing part 300 may include a coupling protrusion coupling part selectively coupled to the coupling protrusion. The coupling protrusion and the coupling protrusion coupling part may be formed in various shapes. For example, the coupling protrusion may include a screw thread. In this case, the coupling protrusion coupling portion may be coupled to the coupling protrusion by including a screw thread. As another embodiment, the coupling protrusion may include a protrusion in the form of a quadrangular pole. In this case, the coupling protrusion coupling portion may include a screw thread, a spiral groove, a straight groove, a straight hole, and the like. By blocking the fixing part 300 with the cover 210 in this way, it is possible to prevent food waste from protruding from the top surface of the fixing part 300 when the primary processing device 200 is operating, and also, the cover 210 It is possible to prevent the user from a safety accident by allowing the primary processing device 200 to operate only when is combined. The operation of the primary processing device 200 by the coupling of the cover 210 will be described in more detail with reference to FIG. 3 .

The fixing unit 300 may be coupled to the grinding housing 280 on which the food waste is seated. In this case, the sealing part 220 may be disposed therebetween to prevent water or food waste from leaking and noise caused by vibration.

When the fixing part 300 is inserted into the drain hole of the sink, it can be fixed with the primary fixing ring 400 on the lower surface of the sink in order to stably couple the fixing part 300 to the sink. Unlike the conventional fixing bracket including a screw thread, the embodiment can derive various effects by applying the primary fixing ring 400 with high fixing force and simple installation. Details of the primary fixing ring 400 will be described later.

The blocking plate 250 may be disposed between the grinding housing 280 and the fixing part 300 . At this time, the blocking plate 250 may be formed in a ring shape, and a part of the blocking plate 250 may protrude into the grinding housing 280 . In this case, the blocking plate 250 may block the movement of the food waste from the grinding housing 250 toward the fixing part 300 when the food waste is pulverized inside the grinding housing 280 .

The fixing ring 260 may be disposed inside the grinding housing 280 . At this time, the fixing ring 260 may be formed integrally or a plurality may be provided to be separated from each other. For example, the fixing ring 260 may include a first fixing ring and a second fixing ring. A portion of the fixing ring 260 may be formed in a concave-convex shape. For example, the first fixing ring may include a first insertion protrusion protruding toward the blade portion (272). In addition, the second fixing ring may include a second insertion protrusion protruding toward the blade portion (272). Each of the first insertion protrusion and the second insertion protrusion may be respectively inserted between the fixing protrusions adjacent to each other. In addition, the fixing ring 260 may include a protrusion protruding from the outer surface. These protrusions may form an angle with the inner surface of the fixing ring 260 . For example, the protrusion may form a right angle with the inner surface of the fixing ring 260 . Through this, the food waste may be crushed together with the blade part 272 . In addition, the protrusion may block food waste that rises when the blade part 272 rotates.

The blade unit 272 may be connected to the rotational force generating unit 278 and rotate according to the driving of the rotating force generating unit 278 . At this time, the blade unit 272 may crush the food waste. The blade portion 272 may have one or more blades formed on one or more of the upper surface, lower surface, and side surfaces of one plate. For example, the blade unit 272 may include a rotating body unit, a protruding blade protruding from the upper surface of the rotating body unit, and an edge blade formed on a side surface of the rotating body unit. In addition, irregularities may be formed on the rim of the rotating body part. The protruding blade may be formed by cutting a portion of the rotating body and bending upward. The protruding blade may include a plurality, and the size of each may be the same or different. In addition, the angle at which each blade faces may also be the same or different. In addition, the plurality of protruding blades may be divided into an inner blade close to the center of rotation and an outer blade formed further away from this. The upper surface of the protruding blade may be formed in multiple stages. In addition, the tip may be formed to be flat.

In addition, the blade unit 272 may include a first rotating unit, a blade fixing unit, and a second rotating unit. In this case, the first rotating unit and the second rotating unit may include the aforementioned blades. The blade fixing part may be disposed between the first rotating part and the second rotating part. At this time, the blade fixing part may be formed in a ring shape, and irregularities may be formed therein. That is, the blade fixing portion is formed of an annular plate, the inside of the blade fixing portion may be formed so that the fixing projection protrudes. At this time, the blade fixing part may be seated in the grinding housing (280). The second rotating unit may be disposed to face the first rotating unit with respect to the blade fixing unit. At this time, the second rotating unit may be coupled to the first rotating unit through screws, bolts, pins, etc. to move together with the first rotating unit. The second rotating unit may include a plurality of blades like the first rotating unit. At this time, the blades of the second rotating unit may be formed to protrude toward the rotating force generating unit 278 .

The blade driving unit 270 includes a rotating shaft coupling unit 271 , a blade unit 272 , a cap 273 , an oil chamber 274 , a first outlet 275 , a bearing 276 , a rotating shaft 277 , a rotational force generating unit. (278), it may include a driving unit case (279).

The driving unit case 279 may have a space formed therein, and the rotational force generating unit 278 may be disposed therein. The driving unit case 279 may be fixed in combination with the grinding housing 280 . The torque generating unit 278 may include a motor. At this time, the motor may receive electricity from the outside to generate rotational force, and may also receive a signal from the controller 240 to control the operation of the motor.

The rotation shaft 277 may be connected to the rotational force generation unit 278 to transmit the rotation generated by the rotational force generation unit 278 to the outside. At this time, the rotating shaft 277 may be connected to the blade portion 272 to rotate the blade portion (272). The bearing 276 may connect the grinding housing 280 and the rotating shaft 277 . At this time, the bearing 276 may support the rotation shaft 277 to be rotatable. The oil chamber 274 may be disposed in the grinding housing 280 to seal between the rotating shaft 277 and the grinding housing 280 or between the rotating shaft 277 and the bearing 276 . In this case, the oil chamber 274 may prevent the water of the grinding housing 280 from flowing out.

The cap 273 may be coupled to the grinding housing 280 to fix the oil chamber 274 . In addition, the rotation shaft coupling portion 271 may be coupled to the rotation shaft 277 to couple the blade portion 272 to the rotation shaft 277 . In this case, the rotating shaft coupling portion 271 and the rotating shaft 277 may be coupled to each other through separate members such as screws, bolts, pins, etc., and a screw thread is formed on the inner or outer surface to be coupled to each other without a separate member. It is possible.

The grinding housing 280 may be combined with the blade fixing part of the blade part 272 . At this time, a space may be formed inside the grinding housing 280, and a first outlet 275 through which food waste and water are discharged may be formed during grinding. In this case, the first outlet 275 may be connected to the secondary processing apparatus 1100 through the connection unit 1600 . At least a portion of the outer surface of the grinding housing 280 is formed to protrude so that the blade fixing part is caught or the position of the fixing ring 260 can be fixed.

The case 230 may be fixed in combination with at least one of the fixing unit 300 , the grinding housing 280 , the blade driving unit 270 , and the sink. In addition, the case 230 may be coupled to the control unit 240 . The case 230 may be coupled while surrounding the fixing part 300 , and may include a sensor to be described later on the inner surface facing the fixing part 300 .

The controller 240 may control the operations of the primary processing apparatus 200 and the secondary processing apparatus 1100 . For example, the control unit 240 may supply power to the torque generating units of the primary processing device and the secondary processing device, and may also transmit a control signal for controlling the operation. The control unit 240, the primary processing device 200, and the secondary processing device 1100 may be connected by wire or wirelessly to transmit and receive signals. For example, the control unit may transmit a signal to operate or stop the operation of the primary processing unit and/or secondary processing unit, and also, when there is an abnormality in the primary processing unit and/or secondary processing unit It can also receive an error signal to stop the operation or send a notification to the user.

Furthermore, the control unit 240 may be connected to an external communication device. For example, the control unit 240 may include a communication module to communicate with an external communication device, for example, a mobile phone, a computer, a laptop computer, a TV, a terminal, and the like. In this case, various types of wireless signals such as Bluetooth, Wi-Fi, and CAN communication may be transmitted and received.

For example, the control unit 240 may be connected to an application that can be installed in an external communication terminal. The user may download and install the application to the user's communication terminal, connect it with the control unit 240 to control the food waste disposal apparatus through an external communication terminal, and check information on the state. Alternatively, the communication module may be disposed in the primary processing device or the secondary processing device to be directly connected to an external communication terminal. Accordingly, the user can directly check the operating state of the primary processing device or the secondary processing device through the communication terminal. For example, in the case of the secondary processing apparatus, it may take more time than the primary processing apparatus that immediately pulverizes food because the food is decomposed by stirring after the injection of microorganisms. In this case, when a large amount of food waste is temporarily injected through the primary processing device, the processing capacity of the secondary processing device may be exceeded. In this case, the current throughput of the secondary processing device, the available throughput, the estimated time until the disassembly is completed, and the like may be transmitted to the user. In addition, when an error occurs in power supply or signal transmission, the user may be notified of this to notify the user to proceed with repair or repair. In this way, the controller 240 may provide a notification to the user through data transmission/reception with an external device as well as controlling the primary processing device and the secondary processing device.

3 is a diagram illustrating in more detail the fixing part 300 of the primary processing apparatus 200 according to an embodiment.

The cover 310 may cover the upper part of the fixing part. A signal generator 330 may be disposed on a side surface of the cover 310 . At this time, the signal generator 330 may generate a signal to the outside. For example, the signal generator 330 may include a permanent magnet. One or more signal generators 330 may be provided, and when a plurality of signal generators 330 are disposed, they may be disposed to be spaced apart from each other along the side surface of the cover 310 . In addition, a sensor 320 may be disposed on the side of the fixing unit 300 to detect a signal generated by the signal generating unit 330 of the cover 310 . Alternatively, the sensor 320 may be disposed inside the case 230 . In this case, one or more sensors 320 may be disposed, and when a plurality of sensors 320 are disposed, they may be disposed to be spaced apart from each other.

On the other hand, looking at the method of primarily grinding food waste through the primary treatment device 200 , when food waste and water are introduced through the drain hole of the sink, it enters the grinding housing 280 . In this case, the user may drive the rotational force generating unit 278 through a separately provided switch. Alternatively, when the cover 310 is fixed to the fixing unit 300 by rotating the cover 310 , the rotational force generating unit 278 may operate. Hereinafter, a method of driving the primary processing apparatus using the cover will be described in more detail.

When food waste and water enter at least one of the fixing unit 300 and the grinding housing 280 , the user may couple the cover 310 to the fixing unit 300 . After that, when the cover 310 is rotated, the signal generator 330 disposed on the cover 310 may also be rotated. Accordingly, when the signal generating unit 330 is moved to a position close to the sensor 320 , the sensor 320 may detect a signal generated by the signal generating unit 330 . For example, the signal generator 330 may include a magnetic material such as a magnet, and the sensor 320 may include a reed switch. In particular, in this case, when the positions of the signal generator 330 and the sensor 320 match, the sensor 320 may detect a signal, which may be transmitted to the controller 240 . As such, when the sensor 320 detects a signal, the control unit 240 determines that the cover 310 has reached the locking position, and may operate the rotational force generating unit 278 .

Hereinafter, the primary fixing ring will be described in detail with reference to FIGS. 4 to 6 .

The primary fixing ring 400 may include a plurality of sub-arms 440 . In one embodiment, the primary fixing ring 400 composed of three sub-arms 440 is described based on, but is not limited thereto, and may be composed of two, four, five sub-arms 440 such as may be The sub-arm 440 may be connected to an adjacent sub-arm through a hinge part 420 . The hinge part 420 may include a hinge hole 421 and a hinge pin 422 that can be inserted into the hinge hole 421 . Through this, the sub-arm 440 can rotate around the hinge part 420 . A fastening part 430 may be included at one end of the sub-arm 440 . The fastening part 430 may be fastened to the other end of the other sub-arm so that the primary fixing ring 400 as a whole forms a closed loop. Each sub-arm 440 may be formed to form a gentle curve inward. Accordingly, when both ends of the sub-arm are coupled through the fastening part 430 , the primary fixing ring 400 may form a circular inner circumferential surface therein. The fastening unit 430 may be applied to various types of fastening units, and is not limited thereto.

In another embodiment, the light emitting unit 450 may be included on the inner surface of the sub-arm 440 . The light emitting unit 450 may implement various functions by irradiating light to the inside of the primary fixing ring 400 , which will be described later.

Figure 5 (a) shows a state in which the primary fixing ring 500 is unfolded. As shown in (a), the primary fixing ring 500 can be rotated through the hinge part, so that it can be unfolded in a straight line. 5 (b) is a view showing a state in which the primary fixing ring 500 is folded around the hinge portion to form a circle shape. In another embodiment, a stopper (not shown) may be disposed on the hinge portion to prevent the sub-arm from being folded more than necessary. Figure 5 (c) shows a shape in which the sub-arm is fastened by the fastening part. When fastened by a fastening part, the primary fixing ring 500 forms a circular shape.

The fixing part 610 is inserted into the drain hole of the upper surface of the sink and protrudes to the lower surface of the sink. The upper surface of the fixing unit 610 has a clasp that is larger than the diameter of the drain hole on the upper surface of the sink so that it can be fixed to the upper surface of the sink when inserted from the upper surface of the sink 620 . In order to stably fix the fixing part 610 to the sink 620, it is necessary to fix the fixing part 610 on the sink lower surface. For example, the fixing part 610 may be fixed by forming a screw thread on the exposed outer surface of the fixing part 610 and inserting a fixing part bracket having a screw thread that can be coupled thereto. However, in the case of the bracket using the screw coupling as described above, the coupling may be loosened by vibration according to the motor of the primary processing device, and it has a disadvantage in that it cannot absorb vibration and noise.

In the embodiment, the fixing part 610 may be stably fixed to the sink 620 by using the primary fixing ring 600 instead of the fixing part bracket. Specifically, as shown in FIG. 6, after inserting the fixing part 610 into the sink drain, the primary fixing ring 600 is wrapped around the outer peripheral surface of the fixing part 610 at the bottom of the sink and the fastening part 630 is fastened. can be fixed. The side of the fixing part 600 may be provided with a groove in which the primary fixing ring 600 can be seated. Therefore, the primary fixing ring 600 is seated in the groove may not flow down. In addition, a flexible packing may be disposed on the upper surface of the primary fixing ring 600 , that is, on the surface in contact with the lower surface of the sink 620 , thereby performing waterproofing and cushioning functions. As described above, according to the embodiment, the fixing part 610 and the sink 620 can be stably fixed by using the primary fixing ring 600 instead of a separate fixing part bracket. Even in the fastening of the primary fixing ring 600, the fastening part 630 can be locked in a snap type, so that it can be easily fastened. In addition, unlike the fixing bracket that is fixed by rotation, it is fixed by applying pressure in the upper direction while filling the gap between the sink and the fixing unit, so that it can be more stable against vibration caused by the rotation of the motor. In addition, since the first fixing ring 600 has rigid sub-arms connected through the hinge part, it can be smoothly fastened to the fixing part outer circumferential surface while maintaining high rigidity.

7 is a view showing a primary fixing ring 700 according to another embodiment. The primary fixing ring 700 illustrated in FIG. 7 may include a light emitting part 740 inside the sub-arm. In the light emitting unit 740 , a plurality of light emitting devices 741 , for example, LEDs may be disposed on the flexible substrate 742 . The light emitting device 741 may be disposed to emit light toward the center of the circle of the primary fixing ring 700 . The substrates 742 disposed on each sub-arm may be electrically connected, and may transmit/receive electrical signals to and from the controller 240 by wire or wirelessly. In addition, the light emitting unit 740 may receive power through the control unit 240, or the primary fixing ring 700 itself may be provided with a power source. A plurality of light emitting devices 741 may be provided and may be spaced apart from each other at regular intervals. The light emitting devices 741 may emit various colors according to the signal of the controller 240 , but are not limited thereto and may emit light of a single color. The light of the light emitting unit 740 may provide various types of notifications to the user.

FIG. 8 is a view showing an example in which the primary fixing ring 700 of FIG. 7 is mounted on the fixing part 610 . (a) of FIG. 8 shows a state in which the cover 210 is coupled to the fixing part 610, and (b) of FIG. 8 shows a state in which the cover 210 is not coupled.

According to FIG. 8 , a portion of the fixing part 610 , at least a region in contact with the primary fixing ring 700 , may be made of a material through which light can pass. Alternatively, the fixing part 610 may be made of a transparent or semi-transparent material through which light can pass as a whole. Therefore, when light is emitted from the light emitting part 740 of the primary fixing ring 700 coupled to the outer circumferential surface of the fixing part 610 , it is transmitted at least partially into the fixing part 610 inside the fixing part 610 . light may be recognized by the user. For example, when the cover 210 is coupled as shown in (a) of FIG. 8 , a portion of the upper surface of the fixing part 610 , for example, the outer annular area of the cover 210 may transmit light. It may be a material that can be Therefore, the user can check the light through it. Alternatively, the cover 210 itself may be formed of a material that can transmit light. In this case, the light may be checked through the cover 210 . Figure 8 (b) is an example when the cover 210 is not coupled. When the cover 210 is not coupled, the user can directly see the inside of the fixing part, so that the light can be recognized.

An example of operation through the light emitting unit 740 of the primary fixing unit 700 will be described.

When the primary processing device and/or the secondary processing device are in an operable state, the light emitting unit 740 may emit light. For example, when power is not supplied to the primary processing device and/or the secondary processing device or when power is cut off, the light emitting unit 740 is turned off, and the light emitting unit 740 is in an operable state. may emit light. Accordingly, the user can check whether the food waste treatment apparatus is in an operable state before putting in the food waste and then drop the food waste. In addition, when there is an error in the primary processing device and/or the secondary processing device, or when an inspection is required, when a user action is required, such as when a microorganism supplement is required, the light emitting unit 740 emits a flashing signal You can also notify users of notifications.

In addition, when the secondary treatment device exceeds the processing capacity and it is necessary to stop inputting the food waste, this signal is transmitted to the controller to stop the operation of the primary treatment device as well. In this case, the current state may be accurately informed to the user by emitting the promised light through the light emitting unit 740 . For example, if the primary processing device simply does not operate in the above case, the user cannot check whether the device is malfunctioning, malfunctioning, or in a state that has to wait for the processing of the secondary processing device. Accordingly, accurate state information can be presented to the user by transmitting the light signal to the user through the light emitting unit 740 .

Specifically, when the light emitting unit 740 can implement various colors, accurate information on the current state can be provided to the user by emitting light in a predetermined color or a blinking cycle. Accordingly, the user's convenience can be greatly improved.

9 provides a fixing unit 900 according to another embodiment.

The fixing part 900 of FIG. 9 may be coupled to the above-described primary fixing ring, as well as using a fixing part bracket other than the primary fixing ring.

The fixing part 900 may include a rubber 910 on the inside. The rubber 910 may prevent vibration and noise according to the operation of the primary processing device. Specifically, the rubber 910 may be formed of a material having elastic force, such as rubber or silicone, and may be disposed in close contact with the inner surface of the fixing unit 900 . Through this, it is possible to absorb the vibration of the fixing unit 900 , thereby reducing noise caused by the vibration of the fixing unit 900 . The rubber 910 may be formed in a cylindrical shape with an empty interior, and may include a groove portion 911 corresponding to the curvature of the inner surface of the fixing portion 900 on the upper surface. In addition, the lower surface of the rubber 910 may include an extension 912 that further extends outward. The extension 912 is formed to be caught on the lower surface of the fixing unit 900 , so that when the rubber 910 is inserted from the lower surface of the fixing unit 900 , it can be fixed at an appropriate position. The rubber 910 may be integrally formed on the inner surface of the fixing unit, or may be inserted into the fixing unit as a separate member as described above. Accordingly, when the rubber 910 is contaminated, it may be replaced.

FIG. 10 is a view showing a state in which the rubber 1010 is mounted on the fixing part 1000 .

As shown in (a) of FIG. 10 , the rubber 1010 may be fixed in close contact with the inner surface of the fixing part 1000 . Fig. 10(b) is a view showing a cross section. As shown in (b) of FIG. 10 , the rubber 1010 is formed to correspond to the internal curvature of the fixing part 1000 , so that it can be in close contact with the inside of the fixing part 1000 . Accordingly, it is possible to effectively attenuate vibration and noise accompanying it.

Another embodiment of the present invention may include an ultraviolet light emitting unit in the primary processing device. The food waste is primarily accommodated in the grinding housing of the primary treatment device, and then mechanically pulverized by the blade driving unit and discharged to the secondary treatment device together with water. In this process, some of the pulverized food waste may remain inside the pulverizing housing. In particular, in the case of sticking to the inner sidewall of the grinding housing, the food waste is not discharged and bacteria, etc. may grow. In order to prevent and sterilize bacteria from the residual food waste, an ultraviolet light emitting unit for irradiating the inside of the grinding housing may be included. That is, it is possible to prevent the spread of bacteria into the air by including an ultraviolet sterilization device for suppressing odor and bacterial propagation in the food waste inlet.

Ultraviolet rays are light in a wavelength range of 10 nm to 400 nm, and among them, ultraviolet rays (100 to 280 nm) of a short wavelength called UVC have a sterilizing effect. UVC is strongly absorbed by the nucleic acids in the cells of microorganisms and destroys the cells. That is, it can be used for sterilization by destroying nucleic acids and destroying DNA at the cellular level.

The ultraviolet light emitting unit may be disposed to irradiate ultraviolet rays inside the grinding housing of the primary treatment device, but is not limited thereto. Illustratively, the ultraviolet light emitting unit may be a part of the light emitting unit of the primary fixing ring. The primary fixing ring may include a plurality of light emitting devices that illuminate the inside of the grinding housing. At least some of them may emit ultraviolet light. That is, some of the plurality of light emitting devices may be LEDs irradiating a wavelength of a visible ray band that provides a notification to a user with a color, and the other part may be an LED irradiating a wavelength of a UVC band in order to sterilize the inside of the grinding housing. Visible light LEDs and UVC LEDs may be arranged alternately, or one UVC LED may be arranged for every plurality of visible light LEDs.

The ultraviolet light emitting unit may be driven by the control unit of the primary processing device. As described above, when included in the light emitting part of the primary fixing ring, it may operate in the same way as the visible light emitting device. Alternatively, it may operate separately from the visible light emitting device. That is, the control unit may distinguish the signal for controlling the visible light emitting device and the signal for controlling the ultraviolet light emitting unit and control them independently. For example, the visible light emitting device may emit light while the primary processing device performs the grinding operation, and the ultraviolet light emitting unit may emit light for a certain period of time after the grinding operation is completed. The specific operation timing may be variously applied according to embodiments, and the present invention is not limited thereto.

The ultraviolet light emitting unit may be mounted on the lower surface of the cover. Referring back to FIG. 3 , FIG. 3 shows an example of irradiating ultraviolet rays into the fixing part 300 by being disposed on the lower surface or the side surface of the cover 310 . The downward arrow shown on the cover 310 of FIG. 3 indicates the irradiation direction of ultraviolet rays. UV light emitting units may be disposed on the lower surface of the cover 310 at regular intervals, or may include UV light emitting units disposed on the side surface of the cover 310 and aligned in the downward irradiation direction.

That is, it is possible to irradiate ultraviolet rays downward from the upper part of the grinding housing. In this case, the cover itself may include a power supply and a control unit for controlling the ultraviolet light emitting unit. Alternatively, power may be supplied from the cover and the control unit of the primary processing device may process the control of the operation. For example, when the control unit receives a signal through the signal generating unit disposed on the side of the cover, the control unit may control the ultraviolet light emitting unit based on the signal. Alternatively, both the power and the control signal may be supplied to the ultraviolet light emitting unit disposed on the cover in the primary processing device.

In addition, the ultraviolet light emitting unit may be disposed in a region other than the above-described primary fixing ring and cover. For example, an arrow pointing toward the inner center of the fixing part 300 shown in FIG. 3 represents an embodiment in which the ultraviolet rays are irradiated toward the center of the grinding housing by being disposed in the fixing part 300 . In this way, the ultraviolet light emitting unit may be disposed on the inner surface of the fixing unit 300 , or the UV light emitting unit may be disposed outside the fixing unit 300 , and the UV light will pass through the fixing unit 300 and be irradiated inside the grinding housing. may be As such, the technical idea of this embodiment is not limited to the specific position as being satisfied as long as the ultraviolet light emitting unit can irradiate ultraviolet light inside the grinding housing, and the ultraviolet light emitting unit may be disposed in various ways.

Another embodiment may further include an antibacterial film inside the grinding housing to prevent bacterial propagation inside the grinding housing. For example, by attaching a film including copper (Cu) to the inner surface of the fixing part or the inner surface of the rubber, it is possible to prevent the propagation of bacteria on the inner surface of the grinding housing.

In another embodiment, an ultraviolet light emitting unit may be disposed to irradiate ultraviolet rays inside the connection portion between the primary treatment device and the secondary treatment device, but the position is not limited thereto.

In another embodiment, an ultraviolet light emitting unit may be disposed to irradiate ultraviolet rays inside the discharge pipe of the secondary treatment device, but the position is not limited thereto.

11 is a view showing the secondary processing device 1100 and the secondary fixing ring 1120 that can be mounted thereto according to an embodiment.

The secondary treatment apparatus 1100 may include a water storage tank 1130 in which food waste can be stirred and a shielding unit 1110 for shielding the upper surface of the water storage tank 1130 . The water storage tank 1130 and the shielding part 1110 may be combined in various ways. In the embodiment, in particular, the coupling through the secondary fixing ring 1120 is shown. The secondary fixing ring 1120 may have a structure similar to that of the primary fixing ring. After the shielding part 1110 is coupled to the upper surface of the water storage tank 1130 , the coupling part is wrapped with the secondary fixing ring 1120 , and then it can be fixed by fastening it with a coupling part. A protrusion may be formed at a coupling portion between the shielding part 1110 and the water storage tank 1130 . For example, the protrusion may be firmly fixed by being fitted into the groove of the secondary fixing ring 1120 and further tightening the secondary fixing ring 1120 through the fastening portion. In addition, a separate sealing member may be inserted into a surface in which the shielding part 1110 and the protrusion of the water storage tank 1130 contact each other, or a sealing member may be formed in the protrusion itself. Accordingly, by being fitted into the groove portion of the secondary fixing ring 1120 while the protrusion is engaged with the sealing portion interposed therebetween, it may be coupled while effectively maintaining the sealing function.

12 is a view specifically showing an example of the secondary fixing ring (1220). The secondary fixing ring may include a plurality of sub-arms 1225 like the primary fixing ring, and may include a hinge portion 1223 for connecting them. The hinge part 1223 may include, for example, a hinge hole 1222 and a hinge pin 1221 that may be inserted into the hinge hole 1222 . In addition, it may include a fastening part 1224 for coupling both ends of the sub-arm. The fastening part of the secondary fixing ring 1220 may have the same structure as the fastening part of the primary fixing ring, but is not limited thereto, and may have a different type of fastening structure. Like the primary fixing ring, the fastening part of the secondary fixing ring may also have a structure that is easy to combine and separate, and various fastening methods may be applied. In addition, a stopper (not shown) may be provided on the hinge portion 1223 of the secondary fixing ring 1220 to prevent the sub-arm from rotating more than necessary. The secondary fixing ring 1220 may also include a light emitting part like the primary fixing ring. However, in this case, since the user cannot see the inside of the secondary processing device 1100, the light emitting part may be mounted on the outer surface of the secondary fixing ring. In this case, status information of the secondary processing apparatus may be displayed through the light emitting unit.

13 and 14 are views illustrating a secondary processing apparatus according to another embodiment.

It is a figure which shows the upper surface of the shielding part 1310 which covers the upper part of the secondary processing apparatus of FIG. 13(a). The shield 1310 may be connected to the primary treatment device through the connection unit 1600 so that food waste and water pulverized in the primary treatment device may flow into the secondary treatment device. The shielding part 1310 may include a shielding body part 1320 , a guide part 1340 , a barrier formed inside the guide part 1340 , and a microorganism input part. The shielding body part 1320 may be formed in a plate shape, and a driving part, a valve, a water supply part, etc. may be disposed on the upper surface. In addition, a supply hole 1450 through which the water and food waste supplied to the connection part 1600 move to the water storage tank 1130 may be formed in the shielding body part 1320 . In this case, the supply hole 1450 may be disposed inside the guide part 1340 . Also, since the supply hole 1450 is disposed at a different portion from the outlet of the connection part 1600 , water and food waste introduced from the connection part 1600 may be prevented from being directly supplied to the supply hole 1450 . The barrier part is disposed inside the guide part 1340 , and may be disposed around the supply hole 1450 . In this case, the barrier portion may be formed to protrude from the upper surface of the shielding body portion 1320 toward the cap portion 1330 . The guide part 1340 is formed to protrude from the shielding body part 1320 toward the cap part 1330, and may form a space therein by forming a closed space. In this case, the guide part 1340 may form a space with the cap part 1330 to form a movement path for water and food waste. In this case, the discharge part of the connection part 1600 may be disposed at one end of the guide part 1320 , and the supply hole 1450 may be disposed at the other end of the guide part 1340 to be spaced apart from the connection part 1600 . In particular, the upper surface of the shielding body part 1320 disposed inside the guide part 1340 may be curved. The microorganism input unit may be formed to protrude from the outer surface of the shielding body part. The microorganism input unit may be formed in the form of a tube to inject the microorganism in powder form. The microorganism input unit may be disposed at a position different from the supply hole 1450 .

The cap part 1330 may be disposed on the upper surface of the guide part 1340 to shield the guide part 1340 . At this time, the cap part 1330 not only forms a movement path for water and food waste together with the guide part 1340 , but also odor flows out through the supply hole 1450 through the connection part 1600 and the primary treatment device. can be prevented from becoming Specifically, when water and food waste move to the supply hole 1450 along the flow path between the cap part 1330 and the guide part 1340 , and water and food waste no longer flow through the connection part 1600 , the It is trapped between the cap part 1330 and the guide part 1340 before reaching. For example, when the user ends using the sink, water may be filled between the cap part 1330 and the guide part 1340 before reaching the barrier part by flowing water last. In this case, since the odor generated in the water storage tank and the stirring container does not move to the connection part 1600 along the supply hole 1450, it is possible to prevent the odor from being leaked to the outside.

In addition, the embodiment may include a valve 1440 blocking the supply hole 1450 . The valve 1440 is disposed in the supply hole 1450 to control opening and closing of the supply hole 1450 . Specifically, FIG. 14A shows a state in which the valve 1440 disposed in the supply hole 1450 is open. When water and food waste are injected into the supply hole 1450 , the valve 1440 is opened so that water and food waste can be introduced into the stirring container. On the other hand, when water and food waste are not introduced, the valve 1440 may be closed to block the supply hole 1450 as shown in FIG. 14B . Therefore, it is possible to fundamentally block the passage through which the odor can flow back. Opening and closing of the valve 1440 may be electronically opened and closed by detecting whether water and food waste are introduced through a sensor. Alternatively, the opening and closing of the valve 1440 may be mechanically controlled. For example, the valve 1440 is made to have an elastic force so that the supply hole 1450 is basically maintained in a closed position, opens when pressure is applied by water and food waste, and when the inflow of water and food waste is stopped, the elastic force is applied. The supply hole 1450 may be restored to the closing position by the method.

15 is a diagram illustrating a specific embodiment of the valve 1540 .

The valve 1540 according to an embodiment has a cover portion 1541 capable of shielding the supply hole, a coupling portion 1543 that can be coupled to the lower surface of the shielding portion, and an elasticity that can apply a restoring force to the cover portion 1541 . portion 1542 . The cover portion 1541 may be formed to be the same as or wider than the diameter of the supply hole to cover the supply hole so as to cover the supply hole. In addition, a sealing member or the like may be included in a region where the cover portion 1541 and the supply hole contact each other to increase airtightness. The coupling part 1543 is a configuration for fixing the cover part 1541 to the lower surface of the shielding part, and may be coupled to the lower surface of the shielding part through various methods such as screws, bolts, and pins. The coupling portion 1543 may have coupling protrusions 1545 formed on both sides thereof. The coupling protrusion 1545 may be inserted into the hole 1544 of the cover part 1541 to be coupled. Accordingly, the cover part 1541 can rotate around the hole 1544 while the position is fixed by the coupling part 1543 . The elastic part 1542 is a means for providing a restoring force, such as a spring, and is not limited to the material or shape thereof, and any means capable of providing a certain force to the rotational movement of the cover part 1541 is possible. An elastic part 1542 may be disposed at a coupling portion between the coupling part 1543 and the cover part 1541 . For example, an elastic part coupling part 1546 may be disposed in one region of the cover part 1541 to fix the elastic part 1542 . The elastic part 1542 may maintain a state in which the cover part 1541 closes the supply hole with a constant force. When a pressure greater than the restoring force of the elastic part 1542 is applied to the cover part 1541 , for example, when water and food waste are introduced through the supply hole to apply pressure to the cover part 1541 , the cover part 1541 . ) is opened, and when the supply of water and food waste is stopped, the cover part 1541 is rotated to its original position, that is, to a position where the supply hole is closed by the restoring force of the elastic part 1542 . As such, the valve 1540 can effectively shield the supply hole without interfering with the inflow of water and food waste through the supply hole, thereby preventing the odor of the water storage tank from flowing backward.

In another embodiment, the valve may be coupled to the outlet of the supply hole. Specifically, the valve may be in the form of a disk having a plurality of wings. The plurality of wings may be connected to the supply hole on the outer circumferential surface of the disk and may be separated from each other in the center. The plurality of wings may be made of a flexible material such as rubber or silicone. Accordingly, when water and food waste are introduced through the supply hole, the plurality of wings may be opened downward to move water and food waste. If water and food waste do not flow in, the wing is closed in the form of a disk, so it is possible to prevent the odor from flowing back.

16 is a diagram illustrating a connection unit 1600 connecting the primary processing device and the secondary processing device. The connection unit 1600 may connect the first outlet 1675 of the primary treatment device and the supply unit 1685 of the secondary treatment device. In addition, the connection part 1600 may include a supply pipe 1620 and a connection part 1610 through which food waste and water can move. The food waste and water pulverized in the primary treatment device may move to the secondary treatment device through the supply pipe 1620 , and may transmit/receive electrical signals to and from each other through the connection unit 1610 . For example, the connection part 1600 may be a pipe. The connection part 1600 may have a straight shape, but may include one or more bent parts. The bent portion may have a U-shape, but may be bent at a predetermined angle while extending in the same direction as shown in FIG. 16 . By forming one or more bent parts in the connection part 1600 , the flow rate of the food waste can be controlled and the odor flowing back from the secondary processing device can be prevented from moving to the primary processing device. In addition, the connection part 1600 may be bent in an S-shape, which may adjust the height of the secondary processing device. For example, since the primary treatment device is installed at the sink drain, the location is constant, but in the case of the secondary treatment device, the installation location may be different depending on the specific surrounding environment. When the connection part 1600 is bent in an S-shape, the position at which the secondary processing apparatus is disposed, particularly the height, may be adjusted by rotating the connection part 1600 . Furthermore, the connection part 1600 may be made of a material having a predetermined flexibility. Therefore, the degree of freedom at the time of installing a secondary processing apparatus can also be raised more.

The connection part 1610 may be combined with the supply pipe 1620 or formed integrally. The connection unit 1610 may include a terminal and a cable, and may include a terminal, a socket, and the like so that the primary processing device and the secondary processing device are electrically connected. Alternatively, terminals, sockets, etc. may be disposed separately from the connection unit 1610 . When the primary processing apparatus and the secondary processing apparatus are electrically connected through the connection unit 1610 , the driving of the primary processing apparatus and the secondary processing apparatus may be organically linked. For example, when the secondary processing device is in a state in which it cannot operate or the available throughput of the secondary processing device may be exceeded, a signal for this may be transmitted to the control unit of the primary processing unit, and the control unit may It may stop the operation of the processing unit. In addition, even when a notification about the state of the secondary processing device is provided to the user through the light emitting unit of the above-described primary fixing ring, the signal of the secondary processing device may be transmitted through the connection unit 1610 . Accordingly, it is possible to prevent the food waste from being properly treated by operating only one of the primary processing device and the secondary processing device. At least one of the primary processing device and the secondary processing device may include a sensor unit for detecting whether the connection unit 1610 is coupled. For example, when the connection unit 1610 is damaged or damaged, or when the connection with the primary processing device or the secondary processing device is cut off, the sensor unit detects this and controls the operation of the primary processing device and the secondary processing device. You can also stop it.

In addition, power may be supplied to the secondary processing device through the connection unit 1610 . For example, external power may be supplied through a control unit coupled to the primary processing device, and the control unit may supply it to the primary processing device. In addition, power may be supplied to the secondary processing device connected through the connection unit 1610 . Accordingly, a separate power source for the secondary processing device may not be provided.

17 is a view showing a cross-section of the connection part 1700 in which the connection part 1710 is formed. One or more connection parts 1710 may be formed on the outer peripheral surface of the connection part 1700 . The connection unit 1710 may include a hole 1720 in which a wire may be disposed. That is, in the hole 1720 of the connection unit 1710, a wire, a cable, or the like capable of transmitting power or an electrical signal may be disposed. The diameter of the hole 1720 may be formed to match the diameter of the wire or cable to be disposed therein, and is not limited to specific values. In this way, by forming the connection part 1710 integrally with the supply pipe 1730 and arranging the wire or cable inside the connection part 1710, it is possible to prevent the wire or cable from being exposed to the outside and being damaged. One or more connection portions 1710 may be formed, and cables required for one hole 1720 may be disposed together, or may be disposed inside different connection portions 1710 according to cables. For example, when the power cable and the signal cable exist separately, each may be arranged inside the other connection unit 1710 so that only the connection unit 1710 for the corresponding cable can be checked in case of a problem.

18 shows a connection unit 1810 according to another embodiment. The connection part 1810 may be formed as a separate member rather than integrally formed with the supply pipe 1811 and then coupled thereto. Specifically, a groove 1820 to which the connection part 1810 can be coupled may be formed on the outer circumferential surface of the supply pipe 1811 . Meanwhile, a protrusion 1830 that can be fitted and coupled to the groove 1820 of the supply pipe 1811 may be formed in the connection portion 1810 . Accordingly, the connection portion 1810 and the supply pipe 1811 may be easily coupled. In this case, when a wire, cable, etc. inside the connection part 1810 is inserted or separated for repair, the connection part 1810 can be separated from the supply pipe 1811 to proceed with the operation, thereby greatly improving user convenience.

The groove 1820 of the supply pipe 1811 may be formed to a predetermined depth from the outer circumferential surface so as not to penetrate the supply pipe 1811 . Accordingly, it is possible to prevent food waste or water passing through the supply pipe 1811 from flowing out through the groove 1820 . Alternatively, if necessary, a groove 1820 may be formed to pass through the supply pipe 1811 , and the protrusion 1830 and the groove 1820 may be coupled while maintaining airtightness. In this case, a separate sealing member may be further included.

19 is a diagram illustrating an embodiment of a secondary processing apparatus.

The secondary treatment apparatus 1900 may include a water storage tank 1930 for accommodating food waste, a shielding unit 1910 covering the upper portion of the water storage tank 1930 , and a microorganism input unit (not shown). Specific details of the shielding unit 1910 can be understood through the above-described description of the shielding unit, and will be omitted below.

A rotational force generating unit 1920 for driving the stirring unit 1960 may be disposed above the shielding unit 1910 . The secondary treatment device 1900 decomposes the food waste by stirring it together with the microorganisms when the firstly pulverized food waste is accommodated together with water. To this end, the rotational force generating unit 1920 transmits the rotational force to the shaft 1951 , and the stirring unit 1950 including the shaft 1951 rotates the blades coupled to the shaft 1951 to agitate the food waste. . The food waste decomposed by the stirring unit 1950 may pass through the filter unit 1954 and flow into the bottom surface of the water storage tank 1930 . A second outlet 1940 is disposed in one area of the bottom surface of the water storage tank 1930 so that the food waste on which the secondary treatment has been completed can be discharged to the outside.

In addition, the secondary treatment apparatus 1900 may further include a separate water supply unit (not shown). The water supply unit may be connected to a sink, water supply, etc. to receive water from the outside. In addition, a valve may be disposed in the water supply unit to control the amount of water supplied through the water supply unit. In addition, the secondary processing apparatus 1900 may include a position sensing unit. The position sensing unit may be disposed on the shielding unit 1910 to detect whether the shaft is rotated by the rotational force generating unit 1920 .

The stirring unit 1950 is a shaft 1950 coupled with the rotational force generating unit 1920 for rotational motion, a filter unit 1954 having a hole through which the shaft 1950 passes through the center, and the filter unit 1954. Arranged on the upper part It may include an upper wing 1952 , a middle wing 1953 , a lower wing 1956 disposed under the filter unit 1954 , and a fixed wing 1955 coupled to the inner surface of the water storage tank 1930 . The agitator 1950 may agitate the food waste input to the water storage tank 1930 with microorganisms to decompose the food waste. To this end, the upper wing 1952 and the middle wing 1953 rotate according to the rotation of the shaft 1951 to mix the food waste with microorganisms. Food waste decomposed by the rotation of the upper wing 1952 and the middle wing 1953 may pass through the filter unit 1954 to move to the bottom of the water storage tank 1930 . The filter unit 1954 includes a plurality of grooves of a predetermined size so that only water and food waste that has been decomposed can selectively pass through the lower portion. The filter unit 1954 may have a mesh shape, for example.

20 is a view showing an example in which the stirring unit 1950 is disposed inside the secondary processing apparatus. A shaft 2050 serving as a center of rotation may be disposed at the center of the secondary processing device. The filter unit 2070 is coupled to the shaft and may be disposed at a higher position than the discharge pipe 2200 . Accordingly, only the residue that has passed through the filter unit 2070 may be discharged to the discharge pipe 2200 . The inner side of the water storage tank 2030 may include a groove to which the fixed blade 2064 can be coupled. That is, the fixed blade 2064 may be fixed to the inner surface of the water storage tank 2030 without rotating.

21 is a view showing a more specific embodiment of the stirring unit. Hereinafter, the function of each configuration of the stirring unit will be described with reference to FIG. 21 .

The upper wing 2110 is a wing disposed at the top. The upper wing 2110 may include a coupling portion 2113 coupled to the shaft 2150 . The coupling part 2113 may be directly coupled to the shaft 2150 or coupled to a member surrounding the shaft 2150 to be indirectly coupled to the shaft 2150 . The upper wing 2110 may include a flat wing 2112 that is bent and extended from the coupling part 2113 and forms a plane substantially parallel to the filter part 2160 . In addition, it may include an inclined blade 2111 extending from one side of the flat blade 2112 while forming an inclination toward the filter unit. 21 , when the inclined blade 2111 has a predetermined angle with the flat blade 2112, the efficiency of stirring can be greatly improved. For example, when the flat blade 2112 and the flat blade 2111 have an angle of 180 degrees, that is, when the two blades are placed on the same plane, the contact area between the inclined blade 2111 and the food waste is small. Therefore, it is difficult to stir. In addition, when the flat blade 2112 and the inclined blade 2111 form an angle of 90 degrees, the area in which the inclined blade and the food waste can contact is wide, but the food waste is moved to the side according to the rotation of the inclined blade 2111 . Since it can only be pushed, the efficiency of stirring decreases. On the other hand, when the inclined blade 2111 is inclined to have an angle between 90 and 180 degrees with the flat blade 2112 as in the embodiment, when the inclined blade 2111 rotates and comes into contact with the food waste, the food waste is disposed on the upper part is pushed in the direction The food waste that rises to the upper part sinks again to the lower part by gravity, and the inclined blade 2111 pushes it upward again. Since the food waste not only rotates but moves up and down by the inclined blades 2111, more efficient agitation is possible. More specifically, the inclined blade 2111 may be formed to have an angle of 100 degrees or more and 160 degrees or less with respect to the flat blade 2112 . Some or all of the inclined blades 2111, the flat blades 2112, and the coupling portion 2113 constituting the upper blade 2110 may be integrally formed. For example, the inclined blade 2111 may be formed by bending a portion of the flat blade 2112 . Alternatively, separate components may be combined with each other. Although the embodiment shows a case in which one inclined blade 2111 is provided, it is also possible for the inclined blade 2111 to be configured in two on both sides of the flat blade 2112 . For example, a second inclined blade (not shown) extending from the other side of the flat blade 2112 may be included. In this case, the inclination angles of the two inclined blades 2111 may be the same, but are not limited thereto and may have different angles.

The middle wing 2120 may be disposed between the upper wing 2110 and the filter unit 2160 . The middle wing 2120 may also perform a function of agitating the food waste with microorganisms in the same manner as the upper wing 2110 . For efficiency of agitation, the upper blade 2110 and the middle blade 2120 may be disposed in opposite directions with respect to the shaft 2150 . The middle blade 2120 may include a coupling part 2121 for coupling with the shaft 2150 , a first inclined blade 2122 , a second inclined blade 2124 , and a flat blade 2123 . Like the upper wing, each part of the middle wing may be integrally formed or separate components may be combined. The first inclined wing 2122 and the second inclined wing 2124 of the middle wing 2120 may extend downward at a constant angle similarly to the inclined wing 2111 of the upper wing 2110 . Accordingly, as described above, the food waste can be pushed upward through the first inclined blade 2122 or the second inclined blade 2124 of the middle blade 2120 , thereby induced vertical movement of the food waste. In addition, the middle wing 2120 may be disposed close to the upper surface of the filter unit 2160 to remove food wastes that have accumulated on the upper surface of the filter unit 2160 . For example, the first inclined blade 2122 may push food waste that has settled on the upper surface of the filter unit 2160 in an upward direction, and the second inclined blade 2124 bent at the opposite side may filter the remaining food waste. It may be pushed in the direction of the part 2160 to be discharged through the filter part 2160 . The first inclined blade and the second inclined blade may be formed to form an angle of 100 degrees or more to 160 degrees or less with respect to the flat blade 2123 , and the inclinations of the first inclined blade and the second inclined blade may be the same. It is not limited and may have different angles. In addition, the first inclined blade 2122 and the second inclined blade 2124 may have the same length, but are not limited thereto, and may have different lengths. In the embodiment, the case in which the middle blade 2120 includes two inclined blades has been exemplarily described, but may include only one inclined blade.

The lower wing 2140 may be disposed under the filter unit 2160 . Similarly, the lower wing 2140 may be coupled to the shaft 2150 , and may rotate according to the rotation of the shaft 2150 . The lower wing 2140 pushes the residue remaining after passing through the filter unit 2160 to the discharge pipe to prevent the pipe from being clogged by sediment. That is, since the lower wing 2140 is not intended for stirring, the rotating surface of the lower wing 2140 may be formed perpendicular to the filter unit 2160 so as to maximize the contact area between the lower wing and the sediment.

In another embodiment, a brush may be disposed on the upper surface of the lower wing 2140 . The brush may be disposed in contact with or close to the lower surface of the filter unit 2160 . Food waste adhering to the lower surface of the filter unit 2160 may be removed through the brush.

The fixed blade 2130 may include a first fixed blade 2131 , a second fixed blade 2133 , and a coupling part 2132 . Unlike other blades, the fixed blade 2130 may be coupled to the inner surface of the water storage tank without being coupled to the shaft 2150 . For example, the coupling part 2132 may be coupled in such a way that it is fitted into a groove formed on the inner surface of the water storage tank. The first fixed blade 2131 and the second fixed blade 2133 may be bent and extended from the coupling portion 2132 . Alternatively, it may be fixed to the coupling unit 2132 through coupling means as a separate configuration. The first fixed blade 2131 and the second fixed blade 2133 may be disposed with a predetermined interval in the vertical direction, and the upper blade 2110 may pass therebetween during rotation. For example, the separation distance between the first fixed blade and the second fixed blade may be set to be greater than the height of the upper blade 2110 . The first fixed blade 2131 and the second fixed blade 2133 may function to release food waste. Specifically, food waste may be agglomerated into agglomerates during the stirring process. In this case, it may not pass through the filter unit 2160 and may float inside the water storage tank, and may also clog the filter unit. When the fixed blades are disposed, the food waste is released by colliding with the first fixed blade and the second fixed blade while rotating, so that the food waste agglomeration can be solved.

In addition, the water storage tank of the secondary treatment apparatus may include an ultraviolet light emitting unit. Since the specific contents of the ultraviolet light emitting unit have been described in the primary processing device, the overlapping contents are omitted. The ultraviolet light emitting unit of the secondary processing apparatus may be disposed to irradiate ultraviolet rays to the lower portion of the filter unit 1954 . That is, after the agitation is completed, the ultraviolet ray may be irradiated to a region that passes through the filter unit 1954 and is discharged to the second outlet 1940 . In the filter unit 1954, the lower wing 1956 rotates and discharges the processed food waste together with water to the second outlet 1940. In this process, residues may remain on the side wall or the bottom surface. Therefore, by irradiating ultraviolet rays to the lower region of the filter unit 1954, it is possible to prevent bacterial growth due to the residue. The ultraviolet light emitting unit of the secondary processing device may be controlled by the control unit of the primary processing device, but is not limited thereto, and the secondary processing device may include a separate control unit and/or a power supply. However, when microorganisms are input in the secondary treatment device, when UV rays are irradiated, the microbes are killed, so the time for decomposing food waste and the time for irradiating UV light are overlapped with the microbes in the secondary treatment device. It is preferable not to do so.

22 is a view showing a discharge pipe 2200 connected to the second outlet 2210 of the secondary treatment device. The food waste decomposed through the secondary treatment device is discharged to the outside through the second outlet 2210 . The second outlet 2210 is coupled to the discharge pipe 2200, and the other side of the discharge pipe 2200 is connected to the sewer, so that the processed food waste can be discharged together with water. On the other hand, even when the treatment is completed through the primary treatment device and the secondary treatment device, it may contain fine suspended matter, and if accumulated for a long time, waste materials may be accumulated on the inner wall of the discharge pipe 2200 . In particular, in the case of the discharge pipe 2200 through which food waste-treated waste is discharged, unlike a general drain through which water mainly moves, the stacking of wastes may be more severe. When wastes are accumulated in the discharge pipe 2200 for a long time, it may cause an odor, and may also cause clogging of the pipe. In order to prevent this, the inside of the discharge pipe 2200 must be frequently washed, but in order to clean the inside of the discharge pipe 2200, the discharge pipe 2200 has to be separated from the secondary treatment device and washed, which is not efficient. In addition, in the discharge pipe 2200, water does not always flow, but water can flow only when the secondary treatment device is operated, so that when the secondary treatment device is not driven for a long time, the inside of the discharge pipe 2200 may become dry. In this case, the residue may be laminated on the inner wall of the discharge pipe 2200 .

The embodiment of FIG. 22 describes a structure in which the pipe cleaning device 2220 is coupled to one region of the discharge pipe 2200 . The pipe cleaning device 2220 may be in the form of a pipe inserted into a hole formed in one area of the discharge pipe 2200 . Specifically, the pipe cleaning device 2220 includes an inlet 2222 that can receive water from the outside, a nozzle 2221 that can spray water into the discharge pipe 2200, and a discharge pipe 2200 to prevent leakage of water. It may include a packing 2223 for. The inlet 2222 of the pipe cleaning device 2220 may be vertically coupled to the discharge pipe 2200 , and the nozzle 2221 may be bent to have an inclination with the inlet 2222 . Specifically, the direction of the nozzle 2221 may be bent along the discharge direction of the food waste residue. Through this, it is possible to prevent the residue from being deposited on the inner wall of the discharge pipe 2200 by spraying water in the discharge direction of the food waste residue.

The inlet 2222 may be connected to the outside to supply water. In addition, the washing liquid may be supplied together with water. The supply of water through the inlet 2222 may be performed in various ways. For example, water may be supplied according to a certain period, or water may be selectively supplied according to whether the sink sink is used, or the operation state of the primary processing device and the secondary processing device. For example, when the secondary treatment device is processing food waste, there is no problem because the residue is continuously discharged together with water to the discharge pipe 2200. However, when the secondary processing device ends the operation, the last residue is It may sink to the lower part of the discharge pipe 2200 . Therefore, when the secondary processing device ends the operation, it may be set to drive the pipe washing device 2220 for a predetermined time. Alternatively, when a sink sink is used, water may be supplied to the pipe washing device 2220 by using a portion of the supplied water.

The nozzle 2221 may include various shapes. For example, water may flow toward the lower surface of the discharge pipe 2200, or the entire inner wall of the discharge pipe 2200 may be washed by spraying water in a spray manner. Also, the spraying method or spraying speed of water through the nozzle 2221 may be different depending on the amount of food waste treated.

23 illustrates a structure in which the pipe cleaning device 2320 is coupled to one area of the second outlet 2310 . Specific functions of the pipe washing device 2320 will be described with reference to the description of FIG. 22 , and will be mainly described with respect to a different part from the embodiment of FIG. 22 .

In the case of the embodiment of FIG. 22 , an example in which the pipe cleaning device 2220 is coupled to the discharge pipe 2200 has been described. That is, the discharge pipe 2200 has a structure coupled to the second outlet 2210 by screwing, and is an embodiment in which the discharge pipe 2200 can be separated from the second outlet 2210 . And, the pipe cleaning device 2220 is installed in the detachable discharge pipe (2200). Meanwhile, in FIG. 23 , a pipe cleaning device 2320 is coupled to a partial region of the second outlet 2310 . That is, in the case of the embodiment shown in FIG. 23 , the pipe cleaning device 2320 may be formed integrally with the second outlet 2310 , more generally, the secondary treatment device. Therefore, in the case of the embodiment of Fig. 23, there is an advantage that the existing discharge pipe 2300 can be combined as it is. For example, in the case of the embodiment of Fig. 22, the exhaust pipe to which the pipe washing device is applied needs to be replaced and installed, whereas in the embodiment of Fig. 23, the pipe washing device while using the existing exhaust pipe as it is. can utilize
