The present invention relates to a food waste disposal apparatus that decomposes food waste by treating and composting food waste using a microbial fermentation and decomposition method. , It relates to a food waste disposal device that can be implemented on a small scale while reducing odor and can be used for home use.

Food waste contains high-concentration organic matter, and when buried in the ground, high-concentration pollutants such as solids and leachate are discharged, causing river pollution and soil pollution, and in particular, by emitting a strong odor, which adversely affects the living environment. do. Accordingly, in the case of food waste, a dedicated collection method has been used, and landfill and incineration methods have been used to treat food waste.

In the present invention, the control commands that can be input by the user refer to the operation conditions of each configuration preset for various functions such as automatic mode, grinding mode, water removal mode, stirring mode, washing mode, etc. When a detailed input possible command for a mode is input using the control device, the driving conditions of each configuration according to each mode or detailed command are stored in the processor 60 and then loaded, and each component is loaded according to the corresponding driving conditions. It will be understood that if a control command to drive is matched with each input and selected, the corresponding control command is transmitted to each configuration.

In addition, in the present invention, each component except for the processor 60 is configured to be separable from the above-described case or mutually separate and combine, so that each component can be separated and washed with water or washed with a dedicated cleaning means during washing. can Alternatively, when the above-described washing module 50 is included in the apparatus of the present invention as an additional configuration, the processor 60 receives the input of the washing mode through the control device, or the grinder 20 according to the automatic setting described later. When it is detected before and after the operation of the washing module 50, the washing liquid is supplied from the inlet hopper 10 to the grinder 20, etc., and functions to clean the inside of the grinder 20.

The inlet hopper 10 is configured to supply water-containing food waste or a microbial preparation for decomposition of food waste to the grinder 20 when the aforementioned microbial supply device does not exist. At this time, in the case of a configuration in which the microbial agent is supplied to the inlet hopper 10 together, the microbial agent may be implemented as a cube or powder type agent that is not mixed with water, for example. Meanwhile, the microbial agent may be supplied through the inlet hopper 10 or introduced through an input unit (not shown) for each stirring tank 411 , 412 , 413 inside the separate stirring device 40 .

On the other hand, when the grinder 20, the transfer and moisture reduction device 30, and the stirring device 40, which will be described later, are driven, food, moisture, odor, etc. are discharged to the outside through the inlet hopper 10, or the grinder 20 An accident may occur because the user's body is caught in the In order to prevent this problem, as shown in FIG. 2, the inlet hopper 10 may be implemented to include a detailed configuration.

Referring to FIG. 2 , the inlet hopper 10 may include a door 11 . The door 11 is installed to cover the inlet of the inlet hopper 10 and is configured to open or close the inlet. For example, it is coupled to the inlet side of the inlet hopper 10 through a hinge 14 to move the hinge It can be implemented to open or close the inlet in one rotational direction.

According to this configuration, when food waste is introduced through the inlet after opening the door 11, the food waste will be guided to be introduced into the agitator 20 through the internal space formed between the outlet 12 and the inlet. . In this case, the contact area between the door 11 and the inlet hopper 10, preferably the area on the opposite side of the hinge 14, has a door detection sensor 15 that detects whether the door is closed. Detailed configuration of the inlet hopper 10 It can be included and installed as

Under this configuration, the processor 60, according to the detection value of the door detection sensor 15, as shown in Figure 3, among the grinder 20, the transfer and moisture reduction device 30, and the stirring device 40 to be described later It will control at least one drive. More specifically, as shown in FIG. 3, a grinder shaft 21 of a grinder 20 to be described later, a rotation shaft 32 of a conveying and moisture reducing device 30, and a stirring tank shaft 42 of a stirring device 40 ) by controlling the rotation of the blade 22 of the grinder 20, the screw 32 of the conveying and moisture reducing device 30, and the shaft blade 43 of the agitator 40 by controlling the rotation of each component It will be understood as controlling the actuation.

On the other hand, in addition to the door detection sensor 15 described above, on the path of the inlet hopper 10, it detects that foreign substances that are not fermented and decomposed by the microbial agent are supplied to food waste input through the inlet hopper 10, A configuration for preventing damage due to foreign substances being introduced into the grinder 20 and the stirring device 40 may additionally be included.

For example, a metal detection device (not shown) may be further included in the present invention for this purpose. The metal detection device includes a magnetic sensor and the like for detecting metal impurities in food waste introduced from the inlet hopper 10 . This is a configuration for detecting metal impurities that are not pulverized by the pulverizer 20 or may cause damage to the pulverizer 20 during pulverization.

At this time, the processor 60 may control the driving of at least one of the grinder 20, the transport and moisture reduction device 30, and the stirring device 40 according to the detection result of the metal detection device. For example, driving of the above components may be stopped. At this time, the inlet hopper 10 has an output means such as an LED, and when the driving of the above-described components is stopped, it can be induced to remove metal impurities in the inlet hopper 10 through control such as turning on the LED. there is.

Meanwhile, as shown in the drawings, the crusher 20 performs a function of pulverizing the food waste introduced from the outlet 12 of the inlet hopper 10 into particles smaller than a predetermined particle size. Although the grinder 20 may be implemented in various ways, for example, a plurality of (for example, 16) grinding blades 22, a grinder shaft 21, a shaft holder, a motor M1, a case, and a sprocket. etc., and the shredder shaft 21 and the shredder blades 22 formed thereon may be installed as shown in FIG. 1 in a plurality of pairs facing each other.

Through this, the food waste introduced through the outlet 12 may be finely pulverized while passing through the pulverizing blades 22 rotating along the shredder shaft 21 that rotates facing each other. Meanwhile, a key may be installed on the shredder shaft 21 so that the crushing blades 22 do not rotate in a reverse direction when food is crushed.

Meanwhile, the grinder 20 may be implemented to rotate with a torque capable of pulverizing only food in order to prevent inflow of various foreign substances, such as plastic and metal, which do not react with microbial agents, to food waste, for example. A sensor (not shown) may be installed on the grinder shaft.

In this case, the processor 60 receives a result of sensing resistance to rotation of the grinder shaft by food waste, foreign matter, etc. through a torque sensor when the grinder shaft is driven, and at this time, when the resistance exceeds a predetermined threshold size , it is determined that foreign substances are included in the objects being pulverized, the operation of the pulverizer 20 is stopped, and an inspection of the pulverizer may be requested to a display device that may be disposed near the above-described control device.

Meanwhile, when the above-described torque of the grinder axis is set to be able to grind only food, the corresponding function may be replaced with a rotation sensor of the grinder axis instead of a torque sensor, and the processor 60 may cause the grinder 20 ) fails to pulverize foreign substances and receives data from the rotation sensor that indicates that the shredder shaft does not rotate or that the rotational speed decreases below the critical speed according to the foreign matter being caught, the operation of the shredder 20 is also received. It is stopped, and an inspection of the grinder can be requested to a display device that can be placed near the above-described control device.

Meanwhile, the conveying and moisture reducing device 30 performs a function of reducing the moisture of food waste discharged from the crusher 20 . The transport and water reduction device 30 may be implemented in various configurations, for example as a kind of solid-liquid separation device. In the present invention, for miniaturization, for example, it may be implemented to include detailed configurations as shown in FIGS. 1, 2, and 4 .

Referring to the above drawings, the transfer and moisture reduction device 30 includes a spiral screw 33 having a rotation shaft 32 whose rotation is controlled by the processor 60, and the screw 33 is accommodated therein. In this way, it is composed of a transport path through which food waste is transported. At this time, in the embodiment of FIG. 2, the transport path means a long space in the longitudinal direction of the inside where the screw 33 and the rotation shaft 32 are accommodated, and the upper part is formed to be connected to the grinder 20. It can be confirmed that the food waste passed through the grinder 20 and pulverized is configured to be put into the conveyance path.

According to this, as the screw 33 rotates, the food waste is transported along the transfer path to the inlet 36 on the agitator 40 side, and at the same time, the torque and gravity applied to the food waste as the screw 33 rotates It will be configured to separate water from food waste by an external force in a direction.

Separation of water can be achieved in a variety of ways. Ultimately, food waste may be transported to the inlet 36 on the agitator 40 side through the screw 33, and water may be discharged through the water outlet 35 as shown in FIG. 4. . Of course, a storage device (not shown) for collecting the separately discharged water may be installed in the water outlet 35 or the water outlet 35 may be configured to be connected to the drain.

In this case, in order to accurately separate and transport moisture and food waste having reduced moisture, structural features of the transport path as shown in FIG. 4 may be included. That is, referring to the contents shown in FIG. 2 by reflecting the bar shown in FIG. 4 , the conveyance path is such that the height of the area into which the food waste discharged from the grinder 20 is introduced is the inlet 36 on the side of the agitator 40 It may be installed inclined so as to be lower than the height of the area. At the same time, a water outlet 35 formed of a mesh filter may be formed in an area into which food waste discharged from the grinder 20 flows. According to this embodiment, the water is moved and discharged through the water outlet 35 having a low height by gravity, and the food waste having reduced water according to the rotation of the screw 33 is pushed by the screw 33. It may be implemented to be transferred to the inlet 36 area while moving to (D1).

Meanwhile, in various embodiments of the present invention, various embodiments for effectively removing moisture may be implemented. First, in the first embodiment, a heating wire is disposed on the screw 33 and heated by power supply, so that the screw 33 touches the screw 33 and moves the food waste, thereby heating the water contained in the food waste. It may be implemented to be evaporated by, or a heating means may be disposed in the inner space itself of the transfer and moisture reduction device 30 so that the moisture is evaporated in the same way.

In this case, the structural features of the transfer path, the water outlet 35, and the inlet 36 are implemented to be inclined in the same way as in the above example, so that when the evaporated water falls or rises, the transport and water reduction device 30 It may be implemented such that it is liquefied while being in contact with the wall of the inner region, and the liquefied moisture flows along the inner wall of the transfer path and is eventually discharged through the moisture outlet 35 .

Meanwhile, in the second embodiment, a filter is formed on the blade surface of the screw 33, and the size of the filter may be implemented to allow water molecules to pass through. Accordingly, water from the food waste is discharged through the filter according to the moving force, torque, etc. in the direction D1 applied by the rotation of the screw 33, and only the food waste from which the water has been removed to some extent is passed through the inlet 36. It can be implemented to move to .

The various structures mentioned in the first and second embodiments may be configured independently or in combination with each other to implement a moisture control function. In addition, in order to control moisture in the above-described first and second embodiments, the processor 60 controls the above-described hot wire or heating means at a preset temperature, or rotates the rotation shaft 32 at a preset rotational speed or torque. rotation can be controlled.

On the other hand, the stirring device 40 mixes food waste with reduced moisture discharged from the transport and moisture reduction device with an internal fermentation and decomposition microbial agent to decompose and compost the food waste, It performs a function of discharging gas to the outside, and as described above, the processor 60 performs a function of controlling the driving of the grinder 20, the transport and moisture reduction device 30, and the stirring device 40. Additionally, as will be described later, driving of the odor reduction module and the cleaning module 50 can be controlled.

The reaction device 40 is configured to include a stirring tank 41, a stirring tank shaft 42, and shaft blades 43, as specifically shown in FIGS. 1, 2 and 5, for example. The stirring tank 41 is a configuration that refers to an internal cavity that is a space in which food waste and microbial agents are mixed. At this time, when the progress of composting through the decomposition of food is completed, the stirring tank 41 can be separated from the apparatus of the present invention as described above so that the composted food waste can be discharged.

On the other hand, in the present invention, the stirring tank 41 is characterized by being composed of a plurality of stirring tank units 411, 412, and 413 that may be included so as to be disposed along the longitudinal direction with each other. At this time, as shown in FIGS. 1 and 5, the areas between the stirring tanks 411, 412, and 413 may be divided from each other through partition walls. The shaft 42 of the stirring tank is configured to pass through each partition wall, and at this time, the mixture of food waste and microbial agents and composted material are prevented from passing between the partition walls and at the same time to protect the shaft 42 of the stirring tank. The penetration area of may be configured to be sealed with a sealing means.

As shown in FIG. 3 , the stirring vessel shaft 42 refers to a shaft rotated within the stirring vessel 41 by the motor M3 whose driving is controlled by the processor 60 . In addition, a plurality of shaft blades 43 are installed on the shaft 42 of the stirring tank in the longitudinal direction of the shaft to mix and agitate the food waste and the microbial agent in the stirring tank 41 . The shaft blades 43 may be implemented such that a plurality of shafts 42 and shaft blades 43 are coupled and installed in the width direction or height direction according to the size of the stirring tank 41 and the size of the area of the stirring tank 41 .

At this time, whether or not the agitator 40, more precisely, the motor M3 is driven and the driving conditions may be controlled by the processor 60 described above. That is, the processor 60 may control the motor M3 so that the stirring tank shaft 42 rotates at a specific rotational speed for a predetermined time through the test, for example, the power is turned on by the control device. and when the automatic mode is turned on, the operation can be controlled so as to operate for a period of time (24 hours to 72 hours) required for the decomposition of food waste by the reaction of the food waste and the microbial agent.

In addition, as mentioned in the example of FIG. 3 described above, when the door 11 is opened and closed according to the detection value of the door detection sensor 15, for example, by the door detection sensor 15, After the motor (M1) of the grinder (20), the motor (M2) of the conveying and moisture reducing device (30) and the motor (M3) of the agitator (40) are driven for a certain period of time, all motors (M1, M2, M3 ) is configured to stop, or after being driven for a certain period of time, the driving of the motor (M1) of the grinder (20) and the motor (M2) of the conveying and moisture reducing device (30) is stopped, and the motor (of the stirring device 40) ( Only M3) can function to be driven continuously.

Meanwhile, in the embodiment shown in FIGS. 2 and 5, a plurality of stirring tanks 411, 412, and 413 are installed in the stirring tank unit. Accordingly, the food waste that has fallen through the inlet 36 is first put into the stirring tank 411 disposed directly below the inlet 36 to be stirred and reacted with the microbial agent. Thereafter, it needs to be transported toward the discharge port 45. At this time, the shaft blades 43 are inclined in the longitudinal direction to transport the food waste in the longitudinal direction, that is, in the direction of arrangement of the stirring tanks 411, 412, and 413, and the food waste And the microbial agent may be implemented to be transported in the longitudinal direction while mixing and stirring.

According to various configuration examples of the shaft blade 43, each of the agitation tanks 411, 412, and 413 included in the agitation tank unit has a height (h1, h2) of the partition wall therebetween and each agitation tank (411, 412, 413). ) may have different lengths (w1, w2, w3) in the longitudinal direction. Accordingly, when food waste and microbial agents mixed and stirred in one stirring tank are piled up to exceed the height of the barrier rib, the food waste may be transported in the longitudinal direction and transferred over the barrier rib to another stirring tank. At this time, the moving direction is preferably 411, 412, and 413 in order as described above.

At this time, the washing liquid is supplied along the inner wall of the inlet hopper 10 through the penetrating part, and the grinder shaft 21 and the blade 22 of the grinder 20 along with the inner wall of the inlet hopper 10 are transported and the moisture reduction device 30 is transported. It can perform the function of cleaning the inner wall of the path, the rotating shaft 32 and the screw 33.

The washing liquid pump 52 serves to supply the washing liquid from the washing liquid tank 51 to the inside of the inlet hopper 10 through the washing liquid line 53 . In this case, the food waste and the washing liquid should not be mixed with each other, and the food waste should flow into the grinder 20 after the washing liquid completely escapes through the above-described water outlet 35 after washing.

To this end, the processor 60 drives the washing liquid pump 52 for a predetermined time before and after driving the grinder 20 (for example, about 5 minutes after the grinder 20 is driven for 15 to 20 minutes), or the user The washing liquid pump 52 may be driven only when the washing mode driving is input.
