Description

food waste disposer

[0001] The present disclosure relates to a food waste disposer, and more particularly, to a built-in type food waste disposer that can be installed inside a sink.

[0002] Generally, food waste disposers are divided into built-in type, which is installed under the sink and is integrated into the sink so that food waste is directly fed into the sink inlet and processed, and standing type, which is installed separately from the sink and collects and processes dehydrated solid food waste.

[0003] In the case of a stand-alone food waste disposer, solid food waste that has undergone dehydration is collected and decomposed into inorganic substances mainly through decomposition using microorganisms, and the decomposed waste is collected and discharged.

[0004] Meanwhile, in the case of a sink built-in food waste disposer, it includes a crusher that crushes food waste fed through the inlet and a dehydrator that dehydrates the crushed food waste.

[0005] Typically, food waste is processed sequentially through grinding and dehydration. Food waste passes through a grinder, a dehydrator, and then is loaded into a loading bin. The liquid separated from the food waste is discharged through a drain hose. Remaining food waste is collected in a food waste collection bin and disposed of once a certain amount has accumulated.

[0006] Users select and use food waste disposers according to the food waste disposal method and installation method, taking into account various factors such as environmental conditions and preferences.

[0007] In particular, the decomposition unit, where food is broken down, is agitated by a mixer and decomposed by microorganisms. However, in humid conditions, the microorganisms in the decomposition unit are dominated by anaerobic microorganisms rather than aerobic microorganisms, which slows down the decomposition process and causes an unpleasant odor.

[0008] Publication patent No. 10-2019-01121611 provides a method for automatically determining the operation of a food waste disposer by comparing measured values ​​with set values ​​using moisture and temperature detection sensors.

[0009] However, the public notice technology has a problem in that the decomposition efficiency of microorganisms may be reduced due to incorrect settings by non-experts by setting the function rate, etc., and it does not disclose an accurate control method according to the function rate.

[0015]

[0016] The purpose of the present disclosure is to provide a built-in type food waste disposer that can collect and remove food waste by fermenting it without crushing it in a sink-integrated food waste disposer.

[0017] In addition, another object of the present disclosure is to provide a food waste disposer that maintains the state of microorganisms in the decomposition section of the food waste disposer at an optimal state.

[0018] In addition, another object of the present disclosure is to provide a food waste disposer that efficiently controls a heater, an exhaust fan, and a stirrer to maintain the state of microorganisms in a decomposition section of the food waste disposer at an optimal state.

[0019] In addition, another object of the present disclosure is to provide a food waste disposer in which a lower module including a decomposition unit is not separated from the main body during operation of the food waste disposer or during an over-humidification process.

[0020] In addition, another object of the present disclosure is to provide a food waste disposer that stops the operation of the agitator and the solid-liquid separator when the lower module including the decomposition unit is separated from the main body during the operation of the food waste disposer.

[0021] In addition, another object of the present disclosure is to provide a food waste disposer that stops the operation of the transport unit when the collection bin is separated from the main body during the operation of the food waste disposer.

[0022] Another object of the present disclosure is to provide a food waste disposer in which a waste transfer unit for collecting only the waste fermented in the decomposition unit into an adjacent collection unit is arranged above the collection unit, thereby utilizing the limited space under the sink and, in particular, minimizing the space other than the space where food is fermented or collected.

[0023]

[0024] The present disclosure is characterized in that it determines the state within the decomposition unit based on the functional ratio within the decomposition unit and performs an operation corresponding to the state within the decomposition unit.

[0025] Specifically, a food waste disposer according to one embodiment of the present disclosure includes a decomposition unit in which food is decomposed by microorganisms, a stirrer for stirring the food and a stirring motor for rotating the stirrer, a moisture content detection sensor for detecting a moisture content of the food in the decomposition unit, a heater for heating the decomposition unit, and a control unit for controlling the decomposition unit, the moisture content detection sensor, and the heater, wherein the control unit is characterized in that it determines a state in the decomposition unit based on a moisture content input from the moisture content detection sensor, and controls the stirring motor and the heater to perform a process corresponding to the state in the decomposition unit.

[0026] The above control unit can determine the state of the inside of the decomposition unit as one of an over-moisture state, a medium-moisture state having a lower moisture content than the over-moisture state, and a low-moisture state having a lower moisture content than the medium-moisture state.

[0027] The control unit, when determining that the state inside the decomposition unit is the over-moisture state, controls the stirring motor to rotate for a first time period and stop for a second time period shorter than the first time period, and controls the heater to maintain the decomposition unit in the first temperature range.

[0028] The control unit, when determining that the state inside the decomposition unit is the medium moisture state, controls the stirring motor to rotate for a third time and stop for a fourth time shorter than the third time, and controls the heater to maintain the decomposition unit in the second temperature range.

[0029] The first time may be longer than the third time, and the second time may be shorter than the fourth time.

[0030] The middle temperature of the first temperature range may be higher than the middle temperature of the second temperature range.

[0031] The control unit, when determining that the state of the inside of the decomposition unit is the low moisture state, can control the stirring motor to rotate for a fifth time period and stop for a sixth time period longer than the fifth time period, and turn off the heater.

[0032] The first time may be longer than the third time, and the third time may be longer than the fifth time.

[0033] The second time may be shorter than the fourth time, and the fourth time may be shorter than the sixth time.

[0034] In addition, the present disclosure further includes an exhaust fan disposed in a path for discharging air within the decomposition unit, and the control unit can rotate the exhaust fan at a first speed when determining that the state within the decomposition unit is the over-moisture state, and can rotate the exhaust fan at a second speed lower than the first speed when determining that the state within the decomposition unit is the medium-moisture state.

[0035] The control unit can rotate the exhaust fan at the second speed when it determines that the state inside the decomposition unit is the low moisture state.

[0036] If the control unit determines that the state of the inside of the decomposition unit is the low moisture state, it can operate the transport unit to transport the food from the decomposition unit to the collection unit.

[0037] The above control unit can output a control signal notifying a processing abnormality when the state inside the decomposition unit is maintained in the over-moisture state for a reference time.

[0038] In addition, the present disclosure further includes a display unit that displays visually recognizable information, and the control unit can output a processing abnormality state through the display unit when the state inside the decomposition unit is maintained in the over-moisture state for a reference time.

[0039] In addition, the present disclosure may further include a main body that accommodates the high-liquid separation unit, the decomposition unit is retractably accommodated in the main body, and may further include a lower locking unit that locks the decomposition unit so that it does not detach from the main body.

[0040] If the control unit determines that the internal state of the disassembly unit is in the over-moisture state, the control unit can control the lower locking unit to maintain a locked state that prevents the disassembly unit from being separated from the main body.

[0041] If the control unit determines that the state inside the decomposition unit is the over-moisture state, it can display through the display unit that the decomposition unit is at a high temperature.

[0042] The above moisture content detection sensor may include at least one of an electrode sensor that measures the resistance of food in the decomposition unit to calculate the moisture content of the food, and an electrostatic capacity sensor that measures the permittivity of food in the decomposition unit to calculate the moisture content of the food.

[0043] The above control unit can output the internal state of the disassembly unit to the screen of the terminal through at least one of an image and text.

[0044]

[0045]

[0046] Through the above solution, the food waste disposer has the advantage of being easy to post-process and environmentally friendly as it decomposes food into microorganisms.

[0047] In addition, the present disclosure controls the food waste disposer so that the moisture content of the food waste in the decomposition section of the food waste disposer is at an optimal moisture content with excellent microbial activity, thereby maintaining the state of the microorganisms in an optimal state, thereby having the advantages of a short decomposition time and excellent energy efficiency.

[0048] In addition, the present disclosure efficiently controls the moisture content of food by controlling the heater, exhaust fan, and stirrer to maintain the state of microorganisms in the decomposition section of a food waste disposer at an optimal state, thereby improving energy efficiency, shortening the decomposition time of food, and quickly changing the moisture content of food to an optimal moisture content.

[0049] In addition, the present disclosure has the advantage of preventing a user from being injured by a hot decomposition part by preventing the lower module including the decomposition part from being separated from the main body during an over-humidification process to lower the moisture content of food.

[0050] In addition, the present disclosure has the advantage of allowing the user to quickly recognize the abnormal state of the microorganisms in the decomposition unit, since it can notify the user in various ways that the state of the moisture content in the decomposition unit of the food waste disposer is bad when the state of the moisture content in the decomposition unit continues in an excessively humid state for a long time.

[0051] In addition, the present disclosure has the advantage of easily controlling the opening and closing of the door by opening and closing the door connecting the transfer section and the decomposition section through which food is discharged from the high-liquid separation section, thereby restricting food that is not decomposed in the decomposition section from moving to the transfer section, and physically synchronizing the opening of the transfer section with the rotation of the transfer section to open the transfer section.

[0090] The expressions referring to directions such as “front (F) / back (R) / left (Le) / right (Ri) / upper (U) / lower (D)” mentioned below are defined as indicated in the drawings, but this is only for the purpose of explaining so that the present disclosure can be clearly understood, and it goes without saying that each direction can be defined differently depending on where the standard is set.

[0091] The use of terms such as "first," "second," etc., preceding components mentioned below is intended solely to avoid confusion regarding the components they refer to, and has no bearing on the order, importance, or dominant-subordinate relationship between the components. For example, an embodiment that includes only the second component and no first component is also possible.

[0092] The thickness and size of each component in the drawings are exaggerated, omitted, or schematically illustrated for convenience and clarity. Furthermore, the size and area of ​​each component do not entirely reflect its actual size or area.

[0093] Additionally, the angles and directions mentioned in the process of describing the structure of the present disclosure are based on those described in the drawings. If the reference point and positional relationship for angles are not clearly mentioned in the description of the structure in the specification, reference should be made to the relevant drawings.

[0094] Hereinafter, a food waste disposer (10) according to the present disclosure will be described with reference to FIGS. 1 to 4.

[0095] FIG. 1 is a front perspective view of a food waste disposer (10) according to one embodiment of the present specification, FIG. 2 is an exploded perspective view of a main body (700) and a lower module (750) of a food waste disposer (10) according to one embodiment of the present specification, FIG. 3 is a perspective view showing the inside of the food waste disposer (10) of FIG. 1, and FIG. 4 is a front view showing the inside of the food waste disposer (10) of FIG. 1.

[0096] The food waste disposer (10) of the present disclosure is a microbial decomposition method, and food waste, which is the object of disposal, is introduced through an inlet (11) located at the top of the food waste disposer (10) and undergoes a decomposition process inside the food waste disposer (10). The composted waste, which is decomposed by microorganisms and turned into compost, is discharged through an outlet (12) located at the bottom of the food waste disposer (10), and is received in a collection unit (500) and then discharged to the outside all at once.

[0097] The food waste disposer (10) can be installed as an integral part (3) inside the sink (1). When the food waste disposer (10) is built into the sink (1), the inlet (100) of the food waste disposer (10) can be provided with a size and shape corresponding to the drain (4) on the bottom surface of the sink bowl (2). Therefore, when the food waste disposer (10) is installed in the sink (1), it can be conveniently used by connecting the inlet (100) of the food waste disposer (10) to the drain (4) of the existing sink bowl (2) without the need for a separate sink bowl (2) for connection.

[0098] The food waste disposer (10) of the present disclosure built into the interior (3) of the sink (1) is implemented to have an upper surface that is arranged parallel to the sink bowl (2) of the sink (1), a lower surface that is parallel to the upper surface and faces the bottom of the sink (1), and front, back, left, and right sides between the upper surface and the lower surface, and to have an internal space.

[0099] The front of the food waste disposer (10) is defined as the side facing the user when the user stands in front of the sink (1), the back is defined as the side that is parallel to the front and faces the back of the sink (1), the side that is bent to the left from the front is defined as the left side, and the side that is bent to the right from the front is defined as the right side.

[0100] In FIGS. 1 and 2, the upper and lower surfaces of the food waste disposer (10) have different areas, and a rear recessed portion (15) is formed according to the difference in the areas of the upper and lower surfaces, and a distributor (not shown) inside the sink (1) (3) can be positioned in the rear recessed portion (15).

[0101] The left and right sides are also formed into a square shape with at least a portion of the side facing the back being sunken by the back recess (15).

[0102] Accordingly, the food waste disposer (10) according to the present disclosure has an overall hexahedral shape, but may have a portion sunken at the lower back, and may be provided in various ways depending on the shape of the sink (1). That is, if the upper inlet (100) of the food waste disposer (10) is arranged so that it can be connected to the drain (4) of the sink (1), and the drain / deodorization module (600) of the food waste disposer (10) is arranged so that it can be connected to the drain pipe of the sink (1), it can be transformed into any structure as long as it has an internal space.

[0103] The food waste disposer (10) is configured with an upper module (710) having an inlet (11) arranged on the upper surface of the food waste disposer (10), a solid-liquid separation unit (200) connected to the inlet and separating the incoming food waste into solids and liquids and transporting the solids, and a lower module (750) arranged below the upper module (710).

[0104] The upper module (710) may include a display unit (14) on the front of the food waste disposer (10) and is integrated into the main body (700) (entire housing) of the food waste disposer (10).

[0105] The display unit (14) can display information about the temperature and humidity within the decomposition unit (300), the degree of maturation, and the remaining filling amount of the collection unit (500).

[0106] The lower module (750) is a functional module for receiving food from the upper module (710) and fermenting and storing it. It is integrated into one module and can be separated from the main body (700) in which the upper module (710) is placed.

[0107] The lower module (750) can be separated from the main body (700) by pulling it out in the first direction, i.e., in the front-back direction, from the front of the food waste disposer (10). By separating the lower module (750), it is possible to directly collect the decomposing matter and microorganisms that are decomposed within the decomposition unit (300) mounted on the lower module (750), and to clean the inside of the decomposition unit (300).

[0108] Various techniques can be applied to facilitate the assembly and separation of the lower module (750) from the main body (700). For example, the lower module (750) can be detached from the main body (700) in a drawer-like manner.

[0109] The input cover (111) covers the inlet (11) so that it can be opened and closed, but is provided to cover most of the area of ​​the inlet (11) so that the odor of the input food does not escape.

[0110] The collection unit (500) stores decomposed food waste. The collection unit (500) implements a sealed structure so that no foul odors generated inside the food waste disposer (10) leak out.

[0111] The food waste disposer (10) of the present disclosure is connected to a water supply pipe formed in a sink (1) and supplies moisture to the inside, and a drain / deodorization module (600) connected to a drain pipe formed in the sink (1) separates solid and liquid from food waste, and the liquid discharged is discharged immediately, while the odor or moisture discharged from each module is guided to be discharged to the drain pipe through the drain / deodorization module (600). Therefore, it has a structure that is directly connected to the water supply pipe and drain pipe of the sink (1), and does not have a separate hole through which odor is discharged to the outside, so when the food waste disposer (10) is operated and the inlet cover (111) is covered, the inside has a sealed structure.

[0112] The collection unit (500) connected to the outlet (12) of the food waste disposer (10) is detachable from the outlet (12). The separated collection unit (500) can empty the collected waste and be reassembled into the food waste disposer (10). The collection unit (500) can be installed in the food waste disposer (10).

[0113] The input cover (111) may be provided in a circular shape so as to be rotatable at the inlet (11). Specifically, the input cover (111) can be secured by simply being fitted into the inlet (11) to ensure a sealing force between the input cover (111) and the inlet (11). Therefore, the coupling of the input cover (111) and the inlet (11) to the extent of fitting or securing is required without performing engagement with the inlet (11) and a screw structure or the like.

[0114] In addition, when the insertion cover (111) is rotated by a predetermined angle or more while in a settled state, the rotation is detected by a sensor, and the settling and start of operation of the insertion cover (111) can be recognized.

[0115] That is, the rotation of the input cover (111) can also be used as an operation switch of the food waste disposer (10). For example, the input cover (111) and the input section (100) to which the input cover (111) is coupled can be provided with a sensing structure of a magnet and a hall sensor. That is, when the input cover (111) is fastened to the inlet (11) and rotated, the hall sensor periodically detects the magnet to recognize the rotational motion, and accordingly, recognizes the start of the operation.

[0116] That is, the operation of the insertion cover (111) being installed and the operation start command of the food waste disposer (10) can be recognized separately. Accordingly, the installation operation of the insertion cover (111) to prevent bad odors and the rotation operation for the operation start command of the food waste disposer (10) are separated, enabling accurate operation start while minimizing user intervention.

[0117] Figures 3 and 4 are a perspective view and a front view showing the inside of a food waste disposer (10) according to the present disclosure.

[0118] Below, the configurations according to the food waste processing process of the food waste processor (10) of the present disclosure are described.

[0119] The input section (100) is the inlet (11) of the food waste disposer (10), and guides food to be input and delivers the food to the solid-liquid separation section (200) at the bottom.

[0120] The solid-liquid separation unit (200) is provided at the bottom of the inlet unit (100) and separates liquid from food moved from the inlet unit (100). In order for food to be easily decomposed, it is desirable for it to have a moisture content below a certain level, and the solid-liquid separation unit (200) separates liquid without crushing it and discharges it into an external sink drain through the drain / deodorization module (600).

[0121] The solid-liquid separation unit (200) can receive water from a water supply unit connected to an external sink water supply pipe and supply it to the lower decomposition unit (300). The interior of the decomposition unit (300) must maintain a certain amount of humidity for microbial activity, and the humidity can be sprayed from the water supply unit (730) of the solid-liquid separation unit (200).

[0122] A water supply part (730) is formed that penetrates from the outside to the inside of the case (201) of the solid-liquid separation part (200), and the water supply part (730) can have a water supply pipe extended so as to be connected to an external water supply pipe. Meanwhile, the internal water supply pipe (730) provided inside the food waste disposer (10) connects the solid-liquid separation part (200) and the external sink water supply pipe through the pipe connection part (732), and the internal drainage / deodorization module (600) connects the solid-liquid separation part (200) and the external drain port through the pipe connection part (680) (see FIG. 10a). The internal drainage / deodorization module (600) is connected so that a part is branched to perform a deodorization function, and also functions as a deodorization module that discharges odors together with liquid into the external drain port.

[0123] The solid-liquid separation unit (200) removes at least a portion of the liquid from the food input from the input unit (100) and moves it linearly or rotationally on a horizontal plane to drop it into the lower decomposition unit (300).

[0124] The decomposition unit (300) can decompose solid food materials using microorganisms. The decomposition unit (300) is located below the solid-liquid separation unit (200) and within the lower module (750). The decomposition unit receives food materials from which liquid has been removed, mixes them with microorganisms, and composts them, thereby decomposing them into compost. Food materials decomposed into compost are decomposed into a form similar to compost with small, uniform particle sizes without the need for separate grinding.

[0125] Accordingly, the decomposed material has a small particle size and a small weight, so it can move along a relatively large trajectory by stirring by the stirrer and be fed into the transfer unit (400) located at the top.

[0126] The collection unit (500) receives food that has been decomposed in the decomposition unit (300) and stores food to be discharged outside the food waste disposer (10) in advance. The collection unit (500) may be arranged horizontally with the decomposition unit (300). The decomposition unit (300) and the collection unit (500) may be partitioned by a side wall (360), and the decomposed matter of the decomposition unit (300) may be moved to the collection unit (500) through a side wall opening formed in the side wall (360).

[0127] The transfer unit (400) transfers at least a portion of the decomposed matter produced in the decomposition unit (300) to the collection unit (500). The transfer unit (400) is arranged horizontally with the decomposition unit (300) and is arranged above the collection unit (500) so that food in the decomposition unit (300) can be moved through the upper opening of the collection unit (500) via the inlet (361) of the side wall (360). The transfer unit (400) moves food in the decomposition unit (300) to the collection unit (500) by mechanical drive.

[0128] That is, when light and small particles of decomposition material are moved upward by the stirring of the decomposition unit (300), they are introduced into the transfer unit (400) through the inlet (361) of the side wall (360) and are discharged into the upper opening of the collection unit (500) through the outlet (12) by the mechanical driving of the transfer unit (400).

[0129] The main body (700), which determines the appearance and volume of the internal space of the food waste disposer (10), mounts each module.

[0130] Specifically, the input section (100) and the solid-liquid separation section (200) are formed integrally within the housing of the main body (700) that forms the exterior of the food waste disposer (10) as an upper module (710), and the decomposition section (300), the collection section (500), and the transport section (400) are mounted within a drawer-type lower module (750) that is physically separable from the housing of the main body (700).

[0131] Below, the detailed configuration of each functional module is described with reference to each drawing.

[0132] Fig. 5 is an exploded perspective view showing the input section of the food waste disposer (10) of Fig. 1, Fig. 6a is a partial cross-sectional view of the input section (100) of Fig. 5 taken along line Ⅰ-Ⅰ', and Fig. 6b is a detailed perspective view of the input cover and cover guide.

[0133] The food waste disposer (10) according to the present disclosure includes an inlet (100) that protrudes from the upper surface of the main body (700) and is aligned with the drain (4) on the bottom surface of the sink bowl (2) of the sink (1).

[0134] The inlet (100) includes a sink lock (120) that is coupled to the inlet of the high-liquid separation unit (200), an inlet cover (111), and a cover guide (130) that is assembled with the inlet cover (111) and detects the presence and start of operation of the inlet cover (111).

[0135] The inlet (2011) of the solid-liquid separation unit (200) is inserted into the drain (4) on the bottom surface of the sink bowl (2) and is connected to the upper opening of the solid-liquid separation unit (200) in the sink (1) to form the input inlet (11) of the food waste disposer (10).

[0136] The inlet (2011) of the high-liquid separation unit (200) is formed to have a diameter equal to or smaller than the diameter of the drain (4) on the bottom surface of the sink bowl (2), but since the diameter of the drain (4) is generally standardized, the inlet (2011) of the high-liquid separation unit (200) can also be manufactured / distributed / sold according to the standard.

[0137] As shown in FIGS. 5 and 6a, the inlet (2011) of the high-liquid separation unit (200) is formed to have a cylindrical side inserted into the drain (4) of the sink bowl (2) and to extend from the side to the upper surface of the sink bowl (2) to cover and compensate for the gap caused by the diameter difference between the drain (4) of the sink (1) and the side.

[0138] At this time, the inlet (2011) of the high-liquid separation unit (200) is formed with a step on the side to form a mounting surface (137) having a narrower diameter than the upper opening, and the mounting surface is formed so that the cover guide (130) is mounted.

[0139] The sink lock (120) is formed on the side of the inlet (2011) of the solid-liquid separation unit (200) and completely covers the space between the sink (1) and the sink bowl (2) and is screw-connected to the side of the inlet (2011) of the solid-liquid separation unit (200) so as to be in close contact with the upper surface of the sink bowl (2). Therefore, the food waste disposer (10) and the sink (1) are connected without a space within the sink bowl (2) by the sink lock (120).

[0140] A cover guide (130) is placed on the side of the sink lock (120).

[0141] The cover guide (130) has a mounting surface (137) on which the insertion cover (111) is mounted, and guides the mounting of the insertion cover (111).

[0142] Specifically, referring to FIG. 6b, the cover guide (130) has a cylindrical structure having a diameter smaller than the side of the sink lock (120).

[0143] The cover guide (130) includes a side (132) that overlaps the side of the sink lock (120) within the side of the sink lock (120), a mounting surface (137) that is bent inward from the lower side of the side (132), and on which the insertion cover (111) is mounted.

[0144] Additionally, the cover guide (130) includes an expansion rim (131) having a step (133) so that the cover guide (130) is mounted on the mounting surface (137) of the inlet of the high-liquid separation unit (200) from the upper side (132).

[0145] The inner surface of the expansion rim (131) has a slope so that it has a predetermined slope from the top to the bottom, and can be formed so that the diameter of the cross-section decreases as it goes downward.

[0146] At this time, the outer surface of the expansion rim (131) can be formed vertically in the up-down direction. Accordingly, a step (133) is formed between the expansion rim (131) and the side surface (132), and the cover guide (130) is supported while the step (133) hangs over the mounting surface of the inlet (2011) of the high-liquid separation unit (200).

[0147] A locker slot (134) is formed on at least a portion of the side (132) of the cover guide (130).

[0148] The locker slot (134) is an opening through which the cover locking unit (280) is inserted into the slot (134) to secure the insertion cover (111) and the cover guide (130).

[0149] The locker slot (134) may be formed as a rectangular opening that is long and opens to have a predetermined width along the side (132), and may include a mountain whose middle region is inclined upwards to correspond to the shape of the arm of the cover locking unit (280).

[0150] At this time, the lower mounting surface (137) may be removed corresponding to the area where the locker slot (134) is formed, but is not limited thereto. That is, when the mounting surface (137) is removed, the mounting surface (137) may have a C shape with a portion removed rather than a ring shape.

[0151] Meanwhile, a guide portion (136) is formed on the inner surface of the expansion rim (131) of the cover guide (130).

[0152] The guide unit (136) provides a light path for guiding and transmitting the guidance indication received from the control unit (not shown) located in the lower high-liquid separation unit (200) to the upper part.

[0153] That is, the guide section (136) is formed of a light-transmitting light-guiding material and is connected to the control section located adjacent to the solid-liquid separation section (200) below by penetrating the expansion rim (131).

[0154] The guide unit (136) provides the user with a guidance display that illuminates from the control unit. At this time, the guidance display may be an indication of the current operating status of the food waste disposer (10), for example, an indication of operation in progress, operation completion, or an error. The indications of operation in progress, operation completion, and error may be briefly indicated by an emitting color, flicker, or the like. Therefore, the user can intuitively recognize the emitting color of the set guide unit (136) and quickly recognize the current status of the food waste disposer (10).

[0155] Since such a guide member (136) is placed on the slope of the expansion forest (131), it can be recognized with the naked eye when the user looks at the drain (4) of the sink bowl (2) from above.

[0156] A feedback magnet (135) can be placed below the guide portion (136) of the cover guide (130), and the feedback magnet (135) can provide resistance when the input cover (111) rotates in conjunction with the magnet (112) of the input cover (111).

[0157] At this time, the magnetic force of the feedback magnet (135) may be greater than the magnetic force of the magnet (112) of the input cover (111).

[0158] The input cover (111) is introduced into the side of the sink lock (120) of the input section (100) and is inserted so as to be placed on the mounting surface (137) of the cover guide (130).

[0159] At this time, the input cover (111) is installed within the cover guide (130) without a separate connection structure such as a screw connection, and can be used as a cover to prevent food from falling out during operation and operation of the food waste disposer (10).

[0160] Specifically, the input cover (111) can be formed into a disc shape having a predetermined thickness so as to be rotatable over the cover guide (130), as shown in FIG. 6b.

[0161] The insertion cover (111) can be implemented with a cover housing (1111) forming a disc and an upper plate (1112) covering the upper portion of the cover housing (1111).

[0162] The cover housing (1111) has a space inside and can be formed in a cylindrical shape. At this time, the diameter of the cover housing (1111) may be smaller than the diameter of the upper plate (1112).

[0163] A predetermined number of magnets (112) can be arranged spaced apart from each other inside the cover housing (1111).

[0164] The magnets (112) are magnets of the same size and magnetic force and are formed to have the same polarity. Such magnets (112) are arranged to have the same spacing distance, and can be formed to be spaced apart from the center point of the cover housing (1111) by a predetermined distance, for example, an angle of 360 / n. n is defined as the number of magnets (112).

[0165] For example, when six magnets (112) are arranged, the magnets (112) can be arranged to have a separation angle of 60 degrees.

[0166] The upper plate (1112) covers the cover housing (1111) and can be finished smoothly and flat to form the upper surface of the input cover (111).

[0167] After the insertion cover (111) is seated on the seating surface (137) of the cover guide (130), it can be rotated by a predetermined angle or more to command the start of operation.

[0168] The food waste disposer (10) of the present disclosure does not rotate to grind or dehydrate food input from the input unit (100) and the solid-liquid separation unit (200). Therefore, the input cover (111) is not required to be completely sealed to the input unit (100), and only a covering force equivalent to that required to prevent the emission of unpleasant odors that may occur during the operation of the food waste disposer (10) by covering the drain (4) is required. Therefore, an engaging shape such as a screw structure is not necessarily required.

[0169] However, the input cover (111) rotates after being installed in the inlet (11), and the rotation of the input cover (111) is recognized by the magnet (112) mounted on the input cover (111) and the Hall sensor mounted on the control unit of the solid-liquid separation unit (200).

[0170] By rotating the input cover (111) in this manner, a command for the settling and operation initiation of the input cover (111) can be artificially generated. That is, the rotation of the input cover (111) can also be used as an operation switch of the food waste disposer (10).

[0171] Specifically, after the insertion cover (111) is installed in the inlet (11) and rotates, the Hall sensor periodically detects the magnet (112) to recognize the rotational motion, and accordingly, recognizes the operation start command.

[0172] That is, the control unit can distinguish and recognize the operation of the insertion cover (111) being installed and the operation start command of the food waste disposer (10). Accordingly, the installation operation of the insertion cover (111) to prevent bad odors and the rotation operation for the operation start command of the food waste disposer (10) are distinguished, enabling accurate operation start while minimizing user intervention.

[0173]

[0174] Below, the main body (700) and the solid-liquid separation unit (200) of the food waste disposer (10) are described.

[0175] Figures 7a and 7b are detailed drawings of the solid-liquid separation unit (200) of the food waste disposer (10) of Figure 1.

[0176] As shown in Fig. 7a, the high-liquid separation unit (200) is placed in the upper module (710) of the main body (700) of the food waste treatment device (10) between the input unit (100) and the decomposition unit (300).

[0177] The solid-liquid separation unit (200) performs the function of filtering liquid from food waste introduced into the inlet unit (100), i.e., food waste introduced directly from the sink bowl (2) of the sink (1), and delivering only solids to the decomposition unit (300).

[0178] The solid-liquid separation unit (200) has an inlet (2011) and an outlet (208). The inlet (2011) is connected to the drain (4) of the sink (1) as described above, and the outlet (208) is arranged on the lower surface of the upper module (710), that is, on the lower surface of the case (201) of the solid-liquid separation unit (200), and communicates with the decomposition unit (300).

[0179] To this end, the solid-liquid separation unit (200) is provided so that at least one area overlaps with the decomposition unit (300), and the outlet (208) of the solid-liquid separation unit (200) is provided so as to be located in this overlapping area. As a result, food discharged through the outlet (208) of the solid-liquid separation unit (200) falls freely and is transferred to the decomposition unit (300).

[0180] The inlet (2011) and outlet (208) of the high-liquid separation unit (200) are arranged so as not to overlap with respect to the second direction, which is the vertical direction.

[0181] For example, the inlet (2011) of the solid-liquid separation unit (200) may be positioned rearward from the front and rear of the food waste disposer (10), and the outlet (208) of the solid-liquid separation unit (200) may be positioned frontward of the food waste disposer (10). Accordingly, the solid-liquid separation unit (200) may horizontally move the input food waste from the rear to the front and transfer it to the decomposition unit (300).

[0182] The high-value separation unit (200) includes a case (201) defining the interior of the upper module (710).

[0183] The case (201) of the high-liquid separation unit (200) has a shape in which the length and depth are greater than the height, and the height is greater than the height of the filter (210) in which the introduced food is initially received, and an inlet (2011) is provided on the upper surface of the case (201), and an outlet (208) is provided on the lower surface.

[0184] At this time, the case (201) can form a hexahedron, and forming a hexahedron means not only having the exact shape of a hexahedron, but also having a cross-section that has a square shape in some part.

[0185] Food in the input unit (100) is delivered to the inlet (2011) of the solid-liquid separation unit (200), and food that has passed through the solid-liquid separation unit (200) moves horizontally and is delivered to the decomposition unit (300) through the outlet (208) of the solid-liquid separation unit (200). The outlet (208) of the solid-liquid separation unit (200) is connected to the inlet of the decomposition unit (300) and the entrance (751) of the lower module (750), so that its shape can be identical to the entrance (751) of the lower module (750).

[0186] The internal space of the high-liquid separation unit (200) defined by the high-liquid separation unit (200) case (201) can be divided into a high-liquid separation space (A) and a transfer space (B).

[0187] The high-liquid separation space (A) may be an area located at the rear within the case (201), and is a space between the inlet (2011) and the drain hole (270) that accommodates the filter (210). The filter (210) may be composed of a cylindrical side portion (211) and a bottom portion (212) that covers the lower opening of the side portion (211), and the side portion (211) includes a filter (210) surface forming the main area of ​​the side, an upper rim (2112) that extends upward from the filter (210) surface, and a lower rim (2113) of the side.

[0188] The side part (211) of the filter (210) is mainly cylindrical and can be implemented as a strainer, i.e., a strainer, in which holes of a predetermined size are formed. Liquid flows out through the side part (211) and is injected into the drain hole connection part (271) along the slope of the bottom surface (2016) of the solid-liquid separation space (A).

[0189] The upper rim (2112) is formed as a slope so that the diameter increases as it goes upward, but the lower rim (2113) can be formed to extend from the side portion (211) and function as a border.

[0190] At this time, it may include at least one fixed projection (2111, 2117) that protrudes from a part of the lower rim (2113) and is fixed to the bottom surface of the high-liquid separation space (A), i.e., the bottom part (212) of the filter (210).

[0191] In addition, the lower rim (2113) may further include at least one side fixing protrusion (2115) that fixes the bottom portion (212) of the filter (210) to the side. The filter (210) is formed so that the side portion (211) and the bottom portion (212) can be separated, and the bottom portion (212) is formed in a closed structure without a hole.

[0192] At this time, the bottom part (212) may be bent upward at a part of the edge to form a joining guide (2121, 2122) that guides the side part (211) of the filter (210).

[0193] The detailed structure of the filter (210) is described later in Fig. 8.

[0194] The filter (210) is separated or combined with the case (201) of the high-liquid separation space (A) in a state where the side part (211) and the bottom part (212) are combined. At this time, the bottom part (212) is a part of the case (201) and the combination guides (2121, 2122), specifically, the area where the combination guides (2121, 2122) extend outside the circumference, and the lower part of the side wall (2015) of the case (201) are combined, and can be separated only by physical pressure.

[0195] When the filter (210) is placed in the high-liquid separation space (A), a gap is formed between the side part (211) of the filter (210) and the case side wall (2015) as shown in Fig. 7d, and only liquid is separated from food waste through the perforations of the side part (211) of the filter (210) in the space created by the gap and flows into the case (201).

[0196] The liquid flowing into the case (201) flows to the bottom surface (2016) of the case through the gap space (2017) between the bottom part (212) of the filter (210) and the case side wall (2015) formed by the extended area of ​​the coupling guide (2121, 2122) when the bottom part (212) of the filter (210) is located in the solid-liquid separation space (A) and is introduced into the discharge hole connection part (271).

[0197] In this way, the bottom part (212) of the filter (210) is not integrated with the bottom surface of the case (201), but is combined in a structure that can be separated when pressurized, so that it can be separated from the case (201) for washing and drying as needed. In addition, by separating the bottom part (212), it is possible to wash the bottom surface of the case (201), i.e., the inclined surface that guides the flow of liquid to the drain hole (270) connected to the drain (4) of the sink (1), to prevent the growth of bacteria, etc.

[0198] The filter (210) can be removed externally by the user lifting it from the inlet (11) of the inlet (100). This has a structure similar to the drain (4) strainer of a conventional sink (1), and the filter (210) can be removed externally for washing and drying, thereby enabling individual management of the space where food comes into contact.

[0199] The case (201) includes a side wall (2015) surrounding the filter (210), and the side wall (2011) can be formed to have a curved surface in an area corresponding to the filter (210). A transfer space (B) is formed in front of the solid-liquid separation space (A).

[0200] The transport space (B) is mainly an empty space, and may be empty when the filter (210) is placed due to movement of the filter (210) by the transport unit (400) or when the filter (210) is retreated.

[0201] The transfer space (B) is open at the bottom, and the open bottom is connected to the entrance of the decomposition unit (300) as the outlet (208) of the high-liquid separation unit (200).

[0202] The case (201) of the high-liquid separation unit (200) surrounding the transfer space (B) can have a bent square shape, and a transfer cover that seals the front of the case (201) can be separately arranged. When the transfer cover that seals the front is separately provided and combined, it can be opened and closed for cleaning and repair.

[0203] The high-liquid separation unit (200) includes a transfer module on one side of the case (201) for moving the filter (210) on a horizontal plane between the transfer space (B) and the high-liquid separation space (A).

[0204] The transfer module may include a transfer motor (220), a pinion (221) connected to a shaft of the transfer motor (220), and a linear rack (222) that moves forward and backward by the pinion (221).

[0205] In addition, the linear rack (222) may further include a guide bar (223) for moving and a transfer body (230) that is bent from the linear rack (222) and has a planar structure facing forward.

[0206] The motor (220) rotates the pinion (221) in one direction to horizontally move the filter (210) from the solid-liquid separation space (A) to the transfer space (B) from rear to front. In addition, the pinion (221) may be rotated in the opposite direction as needed to return the filter (210) from the transfer space (B) to the solid-liquid separation space (A).

[0207] Specifically, when the food is fed into the filter (210) and the feed cover (111) is rotated to recognize the start of operation, the transport motor (220) can be rotated. Alternatively, the transport motor (220) can be operated when a start signal is received from a user, and such a start signal from the user can be received from a user terminal having an application that can be linked with the food waste disposer (10) installed. The rotational drive of the transport motor (220) can be controlled by a control unit.

[0208] The transport motor (220) may be disposed outside the case (201), for example, outside the side of the case (201), but is not limited thereto, and may also be disposed inside the case (201). When the transport motor (220) is disposed outside the case (201), the shaft of the transport motor (220) may penetrate the side wall of the case (201) and be connected to the pinion (221). The pinion (221) engages with the teeth of the linear rack (222) by the shaft of the motor to move the linear rack (222) in a linear direction in the forward and backward directions.

[0209] At this time, a guide bar (223) may be further included to allow the linear rack (222) to move in a forward and backward direction along a horizontal plane.

[0210] The transfer module includes an extension surface (2221) extending vertically (in a second direction) with respect to the longitudinal direction (in a first direction) of the linear rack (222), and the extension surface (2221) extends in the longitudinal direction like the linear rack (222) and is formed integrally with the linear rack (222).

[0211] At least one holder (2222) for holding a guide bar (223) protrudes from the upper and lower portions of the expansion surface (2221). The at least one holder (2222) may be formed in a cylindrical structure through which the guide bar (223) passes, or may be formed in a semicircular shape. If the holder is semicircular, the holders may be arranged to open in opposite directions. Accordingly, the expansion surface (2221) can move in a straight line without shaking along the guide bars (223) installed to pass through a plurality of semicircular holders (2222) at the same time.

[0212] When a plurality of guide bars (223) are arranged, holders (2222) may be provided at the upper and lower portions of the expansion surface (2221), and guide bars (223) may be coupled to the upper and lower holders (2222), respectively, so that the linear rack (222) can move more horizontally and without shaking.

[0213] The guide bar (223) may be an STS guide that is fixed at one end, i.e., the rear end, to the case (201) and maintains the front end in a free state, but is not limited thereto. Alternatively, the linear rack (222) can move in a straight line by calculating the angle in real time and controlling the horizontality, including a horizontal sensor. At this time, the side of the case facing the linear rack (222) may further include a touch sensor (not shown) that detects the position of the protrusion at the bottom of the linear rack (222).

[0214] At this time, the touch sensor is placed at a position that limits the displacement according to the movement of the linear rack (222), and when a touch of the protrusion is detected by the touch sensor, the control unit can stop the operation of the motor (220). The touch sensor (235) can be placed at both ends of the displacement of the linear rack (222).

[0215] A linear rack (222) is arranged inside the side wall of the case (201) and moves in a straight line forward and backward according to the rotation of the pinion (221), and a planar transfer body (230) is arranged in the front by being bent from the front edge of the linear rack (222).

[0216] The transfer body (230) is a coupling member that is combined with the filter (210) to move the filter (210) together when the linear rack (222) moves in a straight line.

[0217] The transfer body (230) forms a cover in itself, and can be formed to have the same area and shape as the cross-section of the case (201) perpendicular to the direction of movement so that the transfer body (230) divides the case (201) of the high-liquid separation unit (200) into front and rear.

[0218] Accordingly, the rear of the transfer body (230), which is the area where food exists, and the front of the transfer body (230), which is the area where no food exists, are separated and sealed from each other. The sealed structure of the transfer body (230) is described in detail in Fig. 9.

[0219] The transfer body (230) is slidably coupled to a fixed part (2114) formed on the side of the filter (210) with the side facing the transfer space (B) to horizontally move the side of the filter (210) to the transfer space (B) according to the movement of the linear rack (222).

[0220] When moving horizontally, only the side part (211) of the filter (210) moves, and the bottom part (212) remains in the solid-liquid separation space (A), so that only the solid matter of the solid-liquid separated food retained in the filter (210) moves to the transfer space (B) and falls to the decomposition unit (300) through the outlet (208) at the bottom.

[0221] Meanwhile, the high-liquid separation unit (200) further includes a separate upper deodorizing module (250) for absorbing and discharging gas containing odor particles inside the case (201) outside the case (201).

[0222] Referring to FIGS. 10c to 10e, the upper deodorization module (250) includes a deodorization pipe (260) connected to a deodorization hole (261) in the side wall of the transfer space (B), one side of which is connected to the deodorization pipe (260), and the other side of which is connected to a leak hole (251) in the side wall of the solid-liquid separation space (A), and is designed to discharge odors to a decomposition unit (300) in which a negative pressure is set through the deodorization pipe (260). The upper deodorization module (250) is designed so that the water leak hole (251) is lower than the deodorization hole (261) to prevent a large amount of water from flowing out of the solid-liquid separation unit (200) through the water leak hole (251) and being injected through the water leak hole (251), and is operable to close the valves (253, 254) when water rises through the valves (253, 254) between the water leak hole (251) and the deodorization hole (261).

[0223] Meanwhile, the high-liquid separation unit (200) may further include a nozzle module (731) connected to the sink (1) water supply pipe to supply a predetermined humidity to the decomposition unit (300).

[0224] When the solid-liquid separation unit (200) includes a nozzle module (731), the nozzle module (731) can be connected to a water supply connection pipe (730) by penetrating the case (201) at the upper part of the transport space (B). Accordingly, the water supply connection pipe (730) extends from the water supply pipe to the nozzle (731) at the upper part of the case (201), and the nozzle module (731) can supply water toward the outlet (208) at the upper part of the transport space (B) by penetrating the upper part of the case (201).

[0225] Such a nozzle module (731) is controlled by a control unit, and can be turned on to spray a predetermined amount of water when the humidity is lower than a predetermined value by a humidity sensor within the decomposition unit (300). However, if the decomposition unit (300) functions as a drying unit that does not contain microorganisms, the nozzle module (731) can be omitted.

[0226] Additionally, one side of the high-value separation unit (200) may further include a cover locking unit (280) for fixing the input cover (111) by penetrating the cover guide (130).

[0227] As described above, the cover locking unit (280) is controlled by the control unit, and when the side of the filter (210) is coupled with the bottom surface of the filter (210) within the solid-liquid separation space (A), the unit detects the coupling, and when the cover guide (130) is seated on the side of the filter (210), the unit detects the seating of the cover guide (130), and when the input cover (111) is seated on the cover guide (130), the unit detects the seating of the input cover (111), and then moves horizontally toward the input cover (111). The cover locking unit (280) includes a fixed hand (281) that is branched to fix one side of the input cover (111), and the fixed hand (281) passes through the locker slit (134) of the cover guide (130) to grasp and fix the side of the input cover (111).

[0228] By fixing the cover locking unit (280) in this way, it is possible to prevent the input cover (111) from coming off due to shaking of food inside the filter (210) when the side of the filter (210) moves horizontally due to the movement of the transfer body (230) under the input cover (111).

[0229] Therefore, even if there is vibration inside, the injection cover (111) can be kept firmly sealed, thereby preventing odor from leaking outside.

[0230] In this way, since the solid-liquid separation unit (200) of this specification does not have an inlet (2011) and an outlet (208) positioned in a straight line in the vertical direction, it performs a filtering (210) of solids and liquids by inputting food, while performing a function of horizontally moving only the filtered solids and dropping them into the lower decomposition unit (300) and introducing them.

[0231] There may be various modifications for the basic module and operation of the high-value separation unit (200), and these are not limited to FIG. 7.

[0232] In addition, the positions of the motor (220), the cover locking unit (280), and the upper deodorizing module (250) are only an example for the high-liquid separation unit (200) of the first embodiment, and various modifications are possible.

[0233] The structure is greatly simplified by the high-liquid separation unit (200) in which only a part of the filter (210), for example, the side part (211), moves horizontally from the rear to the front, and isolation of the decomposition unit (300) is possible.

[0234]

[0235] Hereinafter, the detachable lower module (750) of the present disclosure will be described with reference to FIGS. 8 and 9.

[0236] The lower module (750) that accommodates the disassembly section (300), the transport section (400), and the collection section (500) is packaged as an individual module that can be separated from the main body (700). Since the lower module (750) accommodates the inner case (320) of each module within the lower case (751), each functional module has a double case structure.

[0237] The lower module (750) case (751) can be implemented with the same material as the main body (700) as shown in FIGS. 1 and 2, and is formed in a rectangular parallelepiped shape so as to be insertable into the main body (700).

[0238] Fig. 8 is a perspective view showing the inside of the lower module (750) of the food waste disposer (10) of Fig. 1.

[0239] The inner case (320) defines the positions of the disassembly section (300), the transport section (400), and the collection section (500) and can be provided in the form of a single injection molded product.

[0240] At this time, the transfer unit (400) and the collection unit (500) may have individual cases placed within the inner case (320), but the disassembly unit (300) may have the inner case (320) itself define the space of the disassembly unit (300).

[0241] That is, the decomposition unit (300) is defined as a space for stirring while containing microorganisms and food. The decomposition unit (300) is a space (310) that is maintained mostly empty on one side of the inner case (320), and occupies 1 / 2 to 2 / 3 of the volume of the lower module (750).

[0242] The decomposition unit (300) can be positioned to the lower left of the front of the food waste disposer (10), and the collection unit (500) and the transfer unit (400) are positioned to overlap each other to the lower right.

[0243] Accordingly, the space (310) of the disassembly section (300) maintains a deep concave shape that occupies the entire overlapping length of the collection section (500) and the transfer section (400), and the inner case (320) has a partition wall (380) positioned therein that divides the collection section (500) and the transfer section (400) from the disassembly section (300).

[0244] The decomposition unit (300) within the lower module (750) mixes the solid food material from which the liquid transferred to the decomposition unit (300) has been removed with microorganisms. The mixing of the food material and microorganisms increases the decomposition efficiency.

[0245] When the upper part of the decomposition unit (300) is opened, the opened upper part of the decomposition unit (300) is aligned with the outlet (208) of the case (201) of the solid-liquid separation unit (200).

[0246] At this time, the upper part of the decomposition part (300) may be larger than the outlet (208) of the solid-liquid separation part (200). Since the lower module (750) can be packaged in a separate case (751) and can be independently separated, the user's hand can enter the internal space (310) through the opening in the upper part of the decomposition part (300). Therefore, cleaning the internal space (310) of the decomposition part (300), removing stuck or stuck food, etc. can be facilitated, and if a foreign substance (e.g., a spoon, chopsticks, bottle cap, etc.) is introduced into the lower space (310), it can be easily removed.

[0247] A deodorizing port (322) for connection with a rear drain / deodorizing module (600) is formed in the disassembly section (300). A deodorizing port (322) that can be aligned with a deodorizing fan disposed in the main body (700) at the rear of the case (320) of the disassembly section (300) can be implemented.

[0248] The decomposition unit (300) does not have a separate drainage structure and decomposes dehydrated solid food matter and discharges only the vaporized odor or water vapor through deodorization. Therefore, it does not have a structure connected to the outside except for the deodorizing port (322).

[0249] In some cases, when a separate drainage structure is required, the drawer-type lower module (750) may include a module for connecting a drainage structure for connecting the drain to the sink (1) drain pipe, but alternatively, it may further include a tank for separately collecting and then discharging the liquid.

[0250] In the decomposition unit (300), delivered food and food undergoing decomposition by microorganisms are mixed and accumulated. Among the accumulated food, food that has been completely decomposed becomes compost, with particles that are very small and light in weight.

[0251] Such decomposed matter moves further along a larger trajectory due to the rotation of the mixer due to the difference in weight between it and the newly introduced food, and is transferred to the collection unit (500) through the transfer unit (400) located at the top of the decomposition unit (300).

[0252] The decomposition unit (300) may further include a dryness sensor that detects the dryness of food in the decomposition tank (310).

[0253] For example, the dryness sensor may include an electrode sensor (371) that measures the resistance of food in the decomposition tank (310) to calculate the dryness. The electrode sensor (371) has two electrodes placed in a space where stirring is active in the decomposition tank (310).

[0254] The electrode sensor (371) detects the resistance of the by-product located between the two electrodes by supplying voltage between the two electrodes. If the moisture content within the by-product is high, current flows well, so the resistance value between the electrode sensors is low. On the other hand, if the moisture content within the by-product is low (dry), current does not flow well, so the resistance value between the electrode sensors is high. The difference in these resistance values ​​can be used to indirectly determine the dryness of the by-product.

[0255] As another example, the dryness sensor may include a capacitance sensor (372) that measures the dielectric constant of food within the decomposition tank (310) to calculate the dryness. The capacitance sensor (372) may be installed on the outer surface of the decomposition tank (310) to detect the dryness of the byproduct in a non-contact manner.

[0256] The capacitance sensor (372) may include two capacitance sensors (372) with different sensitivities.

[0257] Since a high sensitivity capacitive sensor can detect low permittivity, it is designed to send a LOW signal when the by-product reaches a certain dryness level, and when this sensor signal goes LOW, it is determined that drying is complete.

[0258] Since the low sensitivity capacitance sensor can detect high permittivity, it is designed to send a HIGH signal when the by-product exceeds a certain moisture content, and when this sensor signal is sent as HIGH, it is determined that the internal state of the decomposition tank (310) is over-humidified, and thus food input can be restricted.

[0259]

[0260] Below, the structure of the collection unit and the combined structure of the collection unit and the transfer unit (400) will be described in detail.

[0261] Figure 9a is a perspective view showing a state in which the transfer unit and the collection unit are separated, and Figure 9b is a perspective view showing a state in which the transfer unit and the collection unit are combined.

[0262] Referring to FIGS. 9a and 9b, the collection unit (500) may be positioned on the lower right side within the inner case (320) of the lower module (750) in the shape of a rectangular parallelepiped.

[0263] The collection unit (500) is inserted into the collection space (326) of the inner case (320) of the lower module (750).

[0264] The collection unit (500) can be individually assembled and separated from the main body (700) as a single module, and can also be assembled and separated from the lower module (750).

[0265] That is, the collection unit (500) is a module that is inserted into the collection space (326) in a state similar to an insertable trash can.

[0266] The collection unit (500) is composed of a collection unit (500) cover (520) and a collection box (510).

[0267] A hinged cover (521) is placed on the cover (520) of the collection unit (500).

[0268] The hinged cover (521) opens when combined with the transfer unit (400) and connects the internal space of the collection box (510) with the exit (12) of the transfer unit (400).

[0269] The hinged cover (521) is closed when the user separates the collection unit (500) from the collection space (326) and takes it out, and when the user re-mounts the collection unit (500) on the food waste disposer (10), it rises up and opens along the inclined surface (475) of the bracket (470) of the transport unit (400). For this purpose, the hinged cover (521) is hinged on the front side.

[0270] Accordingly, when the collection unit (500) is taken out, the user can prevent the garbage from being seen and the foul odor of the garbage can be prevented from escaping.

[0271] The collection box (510) has a concave shape to have an internal collection space, and may have a stepped structure so that it can be used by covering it with vinyl.

[0272] It includes a sensor (530) that can measure the amount of waste in the collection unit (500) so that the user can collect and discard it when a certain amount accumulates in the collection unit (500).

[0273] The sensor (530) of the collection unit (500) may be a weight sensor, and a weight plate (540) is formed on the bottom surface of the collection box (510), and the weight of the waste material can be detected through a load cell at the bottom of the weight plate 540 and transmitted to the control unit.

[0274] The collection unit (500) sensor (530) may, on the other hand, be a water level sensor placed inside the collection space, and various sensors such as an ultrasonic sensor, a laser sensor, and an image sensor can be applied as the water level sensor.

[0275] In this way, the combination and communication of the collection unit (500) and the transfer unit (400) are carried out by sliding combination of the outlet (12) of the transfer unit (400) and the opening / closing cover (521) of the cover (520) of the collection unit (500), so that the user does not feel discomfort due to internal deterioration when removing the collection unit (500), and the two modules can be easily connected and separated.

[0276] In addition, the present disclosure may further include a collection withdrawal detection sensor (496) that detects withdrawal of the collection unit (500). The collection withdrawal detection sensor (496) detects that the collection unit (500) has been separated from the main body (700) and coupled to the main body (700).

[0277] The collection withdrawal detection sensor (496) may include various configurations that detect the position of the collection unit (500). For example, the collection withdrawal detection sensor (496) may detect the position of the opening / closing cover (521) to detect whether the collection unit (500) is engaged. The collection withdrawal detection sensor (496)

[0278] When the collection unit (500) is withdrawn from the main body, the operation of the transport unit (400) is stopped. Specifically, when a signal is input from the collection withdrawal detection sensor (496) that the collection unit (500) has been withdrawn from the main body (700), the control unit can stop the operation of the collection motor (450) of the transport unit (400).

[0279] Accordingly, even if the collection unit (500) is withdrawn from the main body, the operation of the collection motor (450) of the transport unit (400) is stopped, so that damage to the user's body can be prevented even if the user's body enters the inside of the main body (700).

[0280]

[0281] Meanwhile, the food waste disposer (10) of the present disclosure further includes a drainage / deodorization module (600) in the space between the main body (700) and the lower module (750), i.e., the rear space.

[0282] Below, the drainage / deodorization module that discharges odor / vapor from the food waste disposer is described.

[0283] FIG. 10a is a simplified schematic diagram showing the drain deodorization module of the food waste disposer of FIG. 1, FIG. 10b is an enlarged diagram showing the part where the backflow prevention valve of FIG. 10a is installed, FIG. 10c is a simplified schematic diagram showing the drain deodorization module of the food waste disposer of FIG. 1 as viewed from a different direction from FIG. 10a, FIG. 10d is a simplified schematic diagram showing the upper deodorization module of the food waste disposer of FIG. 1, and FIG. 10e is a schematic diagram showing the operation of the upper deodorization module of FIG. 10d.

[0284] Referring to FIGS. 10A and 10B, the internal space of the lower module (750) is defined by a rectangular lower module (750) case (751) having a depth smaller than that of the main body (700).

[0285] Due to this depth difference, a gap exists between the main body (700) and the case (751) of the lower module (750) at the rear of the lower module (750).

[0286] The drain deodorization module (600) discharges liquid separated from food or liquid injected from the inlet (100) into the sink drain pipe, and discharges gas containing odor particles that have passed through the solid-liquid separation unit (200) and the decomposition unit (300) into the sink drain pipe.

[0287] Additionally, the drainage deodorization module (600) can filter out odor particles in the air through a filter (not shown).

[0288] This separation space is positioned toward the lower rear of the entire body (700) of the food waste disposer (10). An exhaust fan (620) is formed at the rear of the separation space, i.e., the rear of the body (700). In addition, a sewage pipe connection part that is connected to the sewage pipe of an external sink (1) is formed at the bottom surface of the separation space, i.e., the bottom surface of the body (700).

[0289] A negative pressure is created inside the food waste disposer (10) by the exhaust fan (620), and the gas containing the odor particles inside is discharged into the sink (1) drain pipe through the deodorizing duct (610) connected to the exhaust fan (620).

[0290] Of course, as another example, although not shown in the drawing, odor particles may be filtered by the filter of the deodorizing duct (610).

[0291] Here, the gas containing odorous particles may include molecules or particles that produce an odor or odor. Furthermore, the gas containing odorous particles may also include water vapor. For example, the odorous particles may include at least one of ammonia, acetaldehyde, methyl mercaptan, and hydrogen sulfide.

[0292] The deodorizing duct (610) is a spiral (snail-shaped) duct (610), and the area facing the exhaust fan (620) on one side is connected to a ventilation hole (322) formed on the rear of the case of the lower module (750), and the other side is connected to a drainage deodorizing pipe (650, 660).

[0293] A connection between the deodorizing duct (610) and the drainage deodorizing pipe (650, 660) can be formed through a connecting unit (630), which can be implemented using an O-ring, etc.

[0294] The drainage deodorization pipe (650, 660) is formed as a pipe having a plurality of bends, connecting a first inlet (656) connected to the sewage pipe (270) of the solid-liquid separation unit (200), a second inlet (661) connected to the deodorization duct (610), and a first outlet (657) connected to the sewage pipe of an external sink (1).

[0295] The drainage deodorization pipe (650, 660) may include a drainage pipe (650) and a deodorization pipe (660). The drainage pipe (650) and the deodorization pipe (660) may be formed integrally or may be formed separately and then combined.

[0296] The drain pipe (650) is connected to the sink drain pipe on one side and discharges liquid separated from food or liquid injected from the inlet into the sink drain pipe.

[0297] The drain pipe (650) is in the form of an S-shaped trap between the first inlet (656) and the first outlet (657), and includes a drain pipe (650) for forming a path for the washing water flowing down from the strainer from the first inlet (656) while allowing the liquid filtered from the solid-liquid separation unit (200) to flow into an external sewer pipe. Since the S-shaped trap always contains water, it can prevent the backflow of odors from the sewer (4).

[0298] Specifically, the drain pipe (650) includes a first inlet (656) connected to the sewage pipe of the solid-liquid separation unit (200) and a first outlet (657) connected to the sink sewage pipe.

[0299] To prevent foul odors from flowing back through the sink drain, the drain pipe (650) may further include a collecting portion (652) where liquid accumulates.

[0300] The reservoir (652) may be located between the first inlet (656) and the first outlet (657). The reservoir (652) may include various configurations, but is preferably a U-shaped pipe convex downward.

[0301] More specifically, the drain pipe (650) may include a first drain pipe (651) having a first inlet (656) at one end and extending vertically, a reservoir (652) connected to the lower end of the first drain pipe (651), a second drain pipe (653) connected to the upper end of the reservoir (652) and extending vertically, a direction changing portion (654) connected to the upper end of the second drain pipe (653) and extending in a direction intersecting with the second drain pipe (653), and a third drain pipe (655) having one end connected to the direction changing portion (654) and the other end provided with a first outlet (657).

[0302] The reservoir (652) may be positioned higher than the second outlet (661). The reservoir (652) may be positioned higher than the first outlet (657) and lower than the first inlet (656). The reservoir (652) may be positioned lower than the direction changer (654).

[0303] Accordingly, the liquid flowing into the sink is prevented from collecting in the sump (652) and flowing back into the sink drain pipe and the upper part of the sink, thereby preventing the bad smell from spreading to the outside.

[0304] The first inlet (656) may be positioned higher than the first outlet (657).

[0305]

[0306] Meanwhile, the deodorizing pipe (660) may have at least one bend between the second inlet (661) and the first outlet (657). The deodorizing pipe (660) has one end connected to the exhaust fan (620) and the other end connected to the drain pipe (650) so that gas containing odor particles flows.

[0307] According to an embodiment, the deodorizing pipe (660) may be connected to at least one of the solid-liquid separation unit (200) and the decomposition unit (300). That is, the deodorizing pipe (660) is connected to the solid-liquid separation unit (200) and the decomposition unit (300), so that the gas containing the odor particles of the solid-liquid separation unit (200) and the decomposition unit (300) can be discharged into the sink drain.

[0308] As another example, the deodorizing pipe (660) may be connected to at least one of the deodorizing duct (610) and the upper deodorizing module (250).

[0309] The deodorizing pipe (660) may include a second inlet (661) connected to the exhaust fan (620) and a second outlet (661) connected to the drain pipe (650). The deodorizing pipe (660) may have an inner diameter that expands from the second inlet (661) toward the second outlet (661).

[0310] The second inlet (661) may be positioned higher than the second outlet (661). The first inlet (656) may be positioned higher than the second outlet (661). The second outlet (661) may be positioned closer to the first outlet (657) than to the first inlet (656) in the drain pipe (650).

[0311] The second inlet (661) may be formed at the right end of the deodorization pipe (660), and the second outlet (661) may be formed at the upper right end of the deodorization pipe (660).

[0312] Of course, the high-value separation unit (200) can be positioned higher than the drainage deodorization pipe (650, 660).

[0313] The drain deodorization module prevents liquid from flowing back into the solid-liquid separation unit (200) or the decomposition unit (300) while the liquid is flowing, and discharges gas containing odor particles that have passed through the solid-liquid separation unit (200) and the decomposition unit (300) into the sink drain while the liquid is not flowing. This control can be implemented electronically by a microcomputer or by a physical force acting on a backflow prevention valve (670) described below.

[0314]

[0315] At this time, a backflow prevention valve (670) is formed between the second inlet (661) and the second outlet (661) of the deodorization pipe (660) to prevent liquid from flowing back from the drain pipe (650) into the deodorization pipe (660).

[0316] The check valve (670) is intended to prevent an accident in which all microorganisms in the decomposition unit (300) die if the liquid flows back into the deodorizing pipe (660) and is injected into the decomposition unit (300). A check valve can be used as the check valve (670).

[0317] A check valve (670) is placed in the deodorizing pipe (660) to limit the backflow of liquid from the drain pipe (650) and allow the flow of gas containing odor particles.

[0318] The check valve (670) restricts the backflow of liquid by the buoyancy of the backflowing liquid and allows the gas containing odor particles to flow by its own weight.

[0319] The check valve (670) can open the deodorization pipe (660) by its own weight and close the deodorization pipe (660) by the buoyancy of the liquid flowing in the deodorization pipe (660).

[0320] When liquid flows in the drain pipe (650), the exhaust fan (620) does not operate and the check valve (670) can close the deodorizing pipe (660). When liquid does not flow in the drain pipe (650), the exhaust fan (620) operates and the check valve (670) can open the deodorizing pipe (660).

[0321] Specifically, the check valve (670) may include a valve body (672) that opens and closes the deodorizing pipe, and the valve body (672) may include a valve hinge (671) that is hinge-connected to the deodorizing pipe.

[0322] The valve body (672) can be rotated about the valve hinge (671). The hinge axis of the valve hinge (671) can extend in a direction intersecting the direction of gravity. Preferably, the hinge axis of the valve hinge (671) can extend in a direction orthogonal to the direction of gravity.

[0323] If the hinge axis of the valve hinge (671) extends in a direction perpendicular to the direction of gravity, it is easy for the valve body (672) to rotate downward by its own weight, and it is advantageous for it to rotate upward by buoyancy.

[0324] The specific gravity of the valve body (672) may be less than the specific gravity of the liquid. When the specific gravity of the valve body (672) is less than the specific gravity of the liquid, when the liquid flows backward, the valve body (672) floats on the liquid due to the buoyancy of the liquid, thereby allowing the valve body (672) to close the deodorizing pipe (660).

[0325] For example, the interior of the valve body (672) may include a hollow space. The hollow space is formed inside the valve body (672), so that it can easily float on a liquid.

[0326] Since the backflow prevention valve (670) is automatically operated by the buoyancy and self-weight of the liquid, a separate operating structure for control is not required, and there is an advantage of no flow resistance compared to the existing valve opening by the wind pressure of the exhaust fan.

[0327] More specifically, the check valve (670) can be raised by the buoyancy of the liquid flowing through the deodorizing pipe (660) to close the second inlet (661) and open the second inlet (661) by the weight of the check valve (670).

[0328] The check valve (670) may be positioned below the second inlet (661). Preferably, at least a portion of the check valve (670) may be positioned to overlap the second inlet (661) in the gravity (up-down) direction.

[0329] The check valve (670) may further include a limit rib (673) that sets a limit to the downward rotation of the valve body (672). The limit rib (673) prevents the valve body (672) from coming into contact with the lower end of the deodorizing pipe (660) and being lifted by the liquid.

[0330] The restriction rib (673) can be formed by protruding from the deodorizing pipe (660).

[0331] In this way, the two paths (650, 660) are integrated and formed between the case of the main body (700) and the case (751) of the lower module (750), which is advantageous in space utilization. In addition, since both sewage and odor are discharged through the drain of the sink (1) without forming a separate odor discharge path, odor discharge to the outside can be prevented, and a separate filter structure for minimizing odor discharge to the outside is unnecessary. Therefore, the product can be simplified and costs can be reduced.

[0332] In addition, when the lower module (750) and the main body (700) are combined, the combination with the deodorizing duct (610) is induced, thereby allowing for a fitting combination without a separate physical combination structure. For this purpose, a sealing portion may be formed between the ventilation hole of the lower module (750) and the deodorizing duct (610).

[0333] At this time, the gas containing odor particles in the solid-liquid separation space (A) is sucked into the transfer space (B) of the solid-liquid separation unit (200) by the upper deodorization module (250) described above, and the odor and moisture are structured to be introduced into the decomposition unit (300) through the outlet (208) of the solid-liquid separation unit (200). Accordingly, the gas containing odor particles in both the upper module (710) and the lower module (750) passes through the deodorization duct (610) through the rear opening (322) in the decomposition unit (300) and is discharged into the deodorization pipe (660).

[0334] The ventilation holes of the lower module (750) are aligned to communicate with the rear opening (322) of the case of the decomposition unit (300), so that negative pressure is formed in the interior of the decomposition unit (300) and the interior space of the solid-liquid separation unit (200) through the opening at the top of the decomposition unit (300), the transfer unit (400), and the collection unit (500) connected to the transfer unit (400), thereby forming an air flow so that all gases containing odor particles can be discharged through the opening (322).

[0335] In addition, a guide seal is formed between the exhaust fan (620) and the deodorizing duct (610), and the guide seal helps the deodorizing duct (610) of the lower module (750) to fit properly into the exhaust fan (620) of the main body (700), while forming a sealed structure that prevents odor from the decomposition unit (300) from escaping to the outside.

[0336] The food waste disposer (10) of the present disclosure includes a control unit for recognizing a start command by rotation of the input cover (111) and controlling each module.

[0337] The control unit can be implemented with a processor or microcomputer, and communicates with various sensors and display units (14) in each module through wired or wireless communication to control the operation of each module accordingly.

[0338] Below, the liquid and odor / vapor paths of the food waste disposer (10) of the present disclosure are described.

[0339] FIG. 10f is a drawing showing the operation when liquid flows in the drain pipe (650) of FIG. 10a.

[0340] Referring to FIG. 10f, when liquid flows through the drain pipe (650), the deodorizing pipe (660) is opened by the check valve (670). Accordingly, the liquid discharged through the sink drain is discharged into the sink drain pipe.

[0341] Figure 10g is a drawing showing the operating state when no liquid flows through the drain pipe (650) of Figure 10a.

[0342] Referring to FIG. 10g, when no liquid flows through the drain pipe (650), the deodorizing pipe (660) is opened by the backflow prevention valve (670). Accordingly, gas containing odor particles generated from the food waste disposal device and gas containing odor particles generated from the sink drain are discharged into the sink drain pipe through the deodorizing pipe (660).

[0343] FIG. 10h is a drawing showing the operation when liquid flows through the drain pipe (650) of FIG. 10a and the liquid flows back through the deodorization pipe (660).

[0344] Referring to FIG. 10f, when liquid flows through the drain pipe (650) and flows back into the deodorizing pipe (660), the buoyancy of the liquid causes the backflow prevention valve (670) to rise, and the deodorizing pipe (660) is closed. Therefore, liquid flowing back from the sink drain does not flow into the interior of the food waste disposer.

[0345]

[0346] Below, the odor / vapor path of the food waste disposer (10) of the present disclosure is described.

[0347] FIG. 10i is a drawing illustrating the odor / vapor path of the food waste treatment device of FIG. 1.

[0348] Referring to FIG. 10i, external air is sucked through the inlet (100) by the negative pressure of the exhaust fan (620) and flows into the solid-liquid separation unit (200) and the upper deodorization module. At this time, the external air also causes gas containing odor particles to flow around the inlet (100) and within the solid-liquid separation unit (200) and the upper deodorization module.

[0349] The gas containing air / odor particles that flows into the high-liquid separation unit (200) and the upper deodorization module (250) passes through the decomposition unit (300) and the deodorization duct (610) in sequence and is discharged into the sink drain through the deodorization pipe (660).

[0350] A portion of the gas containing air / odor particles that has entered the high-liquid separation unit (200) and the resident deodorization module (250) passes through the transfer unit and deodorization duct (610) in sequence and is discharged into the sink drain through the deodorization pipe (660).

[0351]

[0352] Below, the cover locking unit (280') that locks the input cover (111) so that it does not come off from the input port is described in detail.

[0353] FIG. 11a is a cross-sectional view showing a locked state of an inlet cover and a cover locking unit (280') according to another embodiment of the present disclosure, FIG. 11b is a cross-sectional view showing an open state of the inlet cover and the cover locking unit (280') shown in FIG. 11a, FIG. 11c is a drawing showing the inlet cover and the cover locking unit (280') of FIG. 11a and its surroundings, and FIG. 11d is a drawing showing the cover locking unit (280') of FIG. 11a.

[0354] Referring to FIGS. 11A to 11D, a food waste treatment device according to another embodiment of the present disclosure has differences in the structures of the input cover (111) and the cover locking unit (280') from those of FIGS. 1 to 14. Hereinafter, the differences from the structures of FIGS. 1 to 14 will be mainly described, and any configuration without special description will be considered to be the same as that of FIGS. 1 to 14.

[0355] Of course, the structure of the input cover (111) and cover locking unit (280') of Fig. 11 can be combined with the structures of Figs. 1 to 14.

[0356] The cover locking unit (280') locks the input cover (111) so that it does not come off from the input port. That the cover locking unit (280') locks the input cover (111) means that the cover locking unit (280') directly contacts the input cover (111) to limit movement of the input cover (111), or that the cover locking unit (280') does not directly contact the input cover (111) and has a mutual structure that limits movement in one direction.

[0357] The cover locking unit (280') may have a structure capable of locking the input cover (111) while maintaining its balance. The cover locking unit (280') can stably lock the input cover (111) by locking the input cover (111) on both sides of the input cover (111) through one motor, one pinion gear, and two lockers.

[0358] For example, the cover locking unit (280') may include a cover motor (282), a cover pinion gear (283), a first locking arm (285), and a second locking arm (286).

[0359] The cover motor (282) rotates the cover pinion gear (283). The cover motor (282) can be installed in the case (201) of the solid-liquid separation unit (200). The shaft of the cover motor (282) can extend parallel to the vertical direction.

[0360] The cover pinion gear (283) is axially coupled to the cover motor (282) and transmits the rotational power of the cover motor (282) to the first locking arm (285) and the second locking arm (286).

[0361] The first locking arm (285) receives the rotational force of the cover pinion gear (283) and moves in translation to lock or unlock the input cover (111).

[0362] The first locking arm (285) includes a first rack gear (2853) that engages with the cover pinion gear (283) and a first locker (2851) that is connected to the first rack gear (2853) and locks one side of the input cover (111).

[0363] The first locker (2851) moves horizontally through the cover guide (130). The first locker (2851) can lock the input cover (111) through the cover guide (130).

[0364] The first locking arm (285) may further include a first connecting portion (2852) connecting the first locker (2851) and the first rack gear (2853).

[0365] The first locking arm (285) may further include a first guide slot (2854) guided by a locking guide (2231) installed in the high-liquid separation unit (200). The locking guide (2231) may be a protrusion protruding from the case (201) of the high-liquid separation unit (200), and the first guide slot (2854) may be a hole formed in the first connecting unit (2852).

[0366] The second locking arm (286) receives the rotational force of the cover pinion gear (283) and moves in translation to lock or unlock the input cover (111).

[0367] The second locking arm (286) includes a second rack gear (2863) that engages with the cover pinion gear (283) and a second locker (2861) that is connected to the second rack gear (2863) and locks one side of the input cover (111).

[0368] The second locker (2861) moves horizontally through the cover guide (130). The second locker (2861) can lock the input cover (111) through the cover guide (130).

[0369] The second locking arm (286) may further include a second connecting portion (2862) connecting the second locker (2861) and the second rack gear (2863).

[0370] The second locking arm (286) may further include a second guide slot (2864) guided by a locking guide (2231) installed in the high-liquid separation unit (200). The locking guide (2231) may be a protrusion protruding from the case (201) of the high-liquid separation unit (200), and the second guide slot (2864) may be a hole formed in the second connecting unit (2862).

[0371] The second locking arm (286) may further include an arm guide (2865) that guides the first rack gear (2853) of the first locking arm (285). The arm guide (2865) may include a groove formed by recessing a portion of the second rack gear (2863).

[0372] The first locker (2851) and the second locker (2861) may be arranged to face each other with respect to the input cover (111). The first rack gear (2853) and the second rack gear (2863) may be arranged to face each other with respect to the cover pinion gear (283).

[0373] Specifically, the first rack gear (2853) may be gear-coupled to one end of the cover pinion gear (283), and the second rack gear (2863) may be gear-coupled to the other end of the cover pinion gear (283). Accordingly, when the cover pinion gear (283) rotates in one direction, the first rack gear (2853) and the second rack gear (2863) move in opposite directions.

[0374] The first rocker (2851) and the second rocker (2861) can move toward each other when the cover pinion gear (283) rotates forward. The first rocker (2851) and the second rocker (2861) can move toward each other when the cover pinion gear (283) rotates backward.

[0375] Accordingly, when the cover motor (282) rotates forward, the first locker (2851) and the second locker (2861) move toward each other, so that the input cover (111) is locked (in a locked state) as shown in FIG. 11a, and when the cover motor (282) rotates backward, the first locker (2851) and the second locker (2861) move toward each other, so that the input cover (111) is unlocked (in an open state) as shown in FIG. 11b.

[0376] When the solid-liquid separation unit (200) is in operation, the cover locking unit (280') maintains a locked state to prevent the inlet cover (111) from being removed from the inlet. The control unit detects the operation of the solid-liquid separation unit (200), and when the operation of the solid-liquid separation unit (200) is detected, the control unit controls the cover motor (282) to rotate forward. When the operation of the solid-liquid separation unit (200) is not detected, the control unit controls the cover motor (282) to rotate in reverse.

[0377] The input cover (111) may further include a cover catch that catches the first locker (2851) and the second locker (2861). The cover catch vertically overlaps the first locker (2851) and the second locker (2861) in a locked state, thereby restricting vertical movement of the input cover (111) by the first locker (2851) and the second locker (2861). The cover catch may be a protrusion that protrudes outward from a side surface of the input cover (111).

[0378] The cover locking unit (280') may further include a locking detection sensor (287) that detects the locking state of the first locking arm (285) and the second locking arm (286). The locking detection sensor (287) may detect the position of a specific marker of the first locking arm (285) or may be configured as a contact switch that comes into contact with the first locking arm (285).

[0379] The solid-liquid separation unit (200) can be operated only when the first locking arm (285) and the second locking arm (286) are in a locked state. Specifically, the control unit can output a signal for operating the solid-liquid separation unit (200) only when a signal indicating that the first locking arm (285) and the second locking arm (286) are in a locked state is received from the locking detection sensor (287).

[0380]

[0381] Below, the lower locking unit (910) that fixes the disassembly part (300) so that it does not come off from the main body (700) is described in detail.

[0382] FIG. 12a is a drawing showing a food waste disposer and a lower locking unit (910) according to another embodiment of the present disclosure, FIG. 12b is an exploded view of the lower locking unit (910) shown in FIG. 12a, and FIG. 12c is a drawing showing a coupled state of the lower locking unit (910) and the exploded part (300) shown in FIG. 12a.

[0383] Referring to FIGS. 12a to 16c, a food waste disposer according to another embodiment of the present disclosure additionally includes a lower locking unit (910) in the structure of FIGS. 1 to 11. Hereinafter, differences from the structure of FIGS. 1 to 11 will be mainly described, and configurations without special description are considered to be the same as the configuration of FIGS. 1 to 15.

[0384] The lower locking unit (910) locks the disassembly part (300) so that it does not come off from the main body (700). The lower locking unit (910) may have various structures for locking the disassembly part (300).

[0385] For example, it may include a lower motor (911) installed in the main body (700), a lower gear (913) axially coupled to the lower motor (911), a lower rack gear (915) coupled to the lower gear (913), and a lower locker (914) connected to the lower rack gear (915) to lock the disassembly part (300). The lower locker (914) moves in translation in the rotational direction of the lower motor (911).

[0386] The lower locking unit (910) may further include a lower bracket (912) that secures the lower motor (911) to the main body (700). The lower bracket (912) may be installed on the main body (700). The lower bracket (912) may accommodate the lower gear (913) and guide the lower rack gear (915).

[0387] The disassembly section (300) may further include a lower slot (3201) into which a lower locker (914) is inserted. Specifically, the lower slot (3201) may be formed at one end of the inner case (320) to define a space through which the lower locker (914) passes.

[0388] Specifically, the lower slot (3201) may be a hole that penetrates in the vertical direction. The lower rocker (914) moves downward when the lower motor (911) rotates forward, and moves upward when the lower motor (911) rotates backward.

[0389] When the solid-liquid separation unit (200) is in operation, the locking unit maintains a locked state to prevent the disassembly unit (300) from being separated from the main body (700). Specifically, when the solid-liquid separation unit (200) is in operation, the control unit rotates the lower motor (911) forward to maintain a locked state to prevent the disassembly unit (300) from being separated from the main body (700). At this time, the lower locker (914) is positioned to overlap the lower slot (3201) in the horizontal direction.

[0390] As shown in Fig. 12e, in the locked state of the lower locking unit (910), the lower locker (914) is inserted into the lower slot (3201) to prevent the disassembly part (300) from being detached.

[0391] When the solid-liquid separation unit (200) is not operating, the lower locking unit (910) maintains an open state in which the decomposition unit (300) can be separated from the main body (700). Specifically, when the solid-liquid separation unit (200) is not operating, the control unit rotates the lower motor (911) in reverse to maintain the open state in which the decomposition unit (300) can be separated from the main body (700). At this time, the lower locker (914) is positioned so as not to overlap the lower slot (3201) in the horizontal direction.

[0392] As shown in FIG. 12d, in the open state of the lower locking unit (910), the lower locker (914) is positioned outside the lower slot (3201) to allow the disassembly part (300) to be removed.

[0393]

[0394] Below, the disassembly withdrawal detection sensor (920) that detects withdrawal of the disassembly unit (300) is described in detail.

[0395] FIG. 17a and FIG. 17b are drawings showing the operation of a disassembly extraction detection sensor (920) according to one embodiment of the present disclosure.

[0396] Referring to FIGS. 17a and 17b, a food waste treatment device according to another embodiment of the present disclosure additionally includes a disassembly and extraction detection sensor (920) in the structure of FIGS. 1 to 12. Hereinafter, differences from the structure of FIGS. 1 to 12 will be mainly described, and configurations without special description are considered to be the same as the configuration of FIGS. 1 to 16.

[0397] The disassembly and withdrawal detection sensor (920) can detect whether the disassembly part (300) is withdrawn from the main body (700). In addition, the disassembly and withdrawal detection sensor (920) can cut off the power between the stirring motor (330) and the power supply (not shown) when the disassembly part (300) is withdrawn from the main body (700), and can connect the power between the stirring motor (330) and the power supply when the disassembly part (300) is coupled to the main body (700).

[0398] The disassembly extraction detection sensor (920) may include a press switch (921) that is pressed by the disassembly unit (300) to electrically connect the stirring motor (330) and the power supply. A roller (9211) may be arranged on the press switch (921). The press switch (921) may selectively connect a terminal (922) connected to the stirring motor (330) and a terminal (923) connected to the power supply.

[0399] The push switch (921) can cut off the stirring motor (330) and the power supply by elastic force when the disassembly part (300) is pulled out from the main body (700).

[0400] When the high-liquid separation unit (200) is in operation, the cover locking unit (280') can lock the input cover (111) to prevent it from being removed from the input port, and the lower locking unit (910) can lock the decomposition unit (300) to prevent it from being removed from the main body (700). The operation of the decomposition unit (300) can be stopped when the withdrawal of the decomposition unit (300) is detected. The stirring motor (330) can be stopped when the withdrawal of the decomposition unit (300) is detected.

[0401] The motor (220) of the solid-liquid separation unit (200) can be stopped when the withdrawal of the decomposition unit (300) is detected. The control unit can stop the motor (220) and the stirring motor (330) of the solid-liquid separation unit (200) when the withdrawal of the decomposition unit (300) is detected.

[0402]

[0403] Hereinafter, another embodiment of a high-liquid separation unit (200) applicable to the present specification will be described with reference to FIG. 18.

[0404] Fig. 18 is a cross-sectional view of a high-liquid separation unit according to another embodiment of the present disclosure.

[0405] Referring to FIG. 18, a high-liquid separation unit (200') according to another embodiment of the present disclosure has a difference in that the high-liquid separation unit (200) of the first embodiment and the bottom unit (212) are inclined upward as they approach the transfer space (B) in the high-liquid separation space (A).

[0406] The bottom part (212) is formed to slope upward from the rear to the front, and when the side part (211) moves along the upper surface of the bottom part (212) while scraping the food, the bottom part (212) is arranged to slope downward toward the rear, so the liquid separated from the food cannot pass to the transfer space (B) but falls to the solid-liquid separation space (A).

[0407] At this time, the transfer module can move the side part (211) horizontally and inclinedly forward and backward.

[0408] Additionally, depending on the embodiment, the high-liquid separation unit (200') may be installed with an incline with respect to the horizontal direction. That is, the high-liquid separation unit (200) may be arranged with an upward incline from the rear to the front.

[0409]

[0410] Hereinafter, the control configuration of the present disclosure will be described.

[0411] FIG. 13 is a drawing showing a control configuration of a food waste disposer (1) according to one embodiment of the present disclosure.

[0412] The food waste disposer (1) of the present disclosure includes a moisture content detection sensor (1200), a heater (328), and a control unit (1800). The food waste disposer (1) of the present disclosure may further include at least one of a temperature sensor (1100), a speaker (1400), an inlet light (113), a display unit (14), an exhaust fan (620), a collection motor (450), and a stirring motor (330).

[0413] The moisture content detection sensor (1200) detects the moisture content of food (decomposed matter) within the decomposition unit (300) and provides the moisture content value to the control unit (1800). The moisture content detection sensor (1200) can also detect the moisture content within the decomposition unit (300).

[0414] For example, referring to FIG. 8b, the moisture content detection sensor (1200) may include an electrode sensor (371) that measures the resistance of food in the decomposition tank (310) to calculate the dryness (or moisture content). The electrode sensor (371) is an electrode having two poles placed in a space where stirring is active in the decomposition tank (310).

[0415] The electrode sensor (371) detects the resistance of the by-product located between the two electrodes by supplying voltage between the two electrodes. If the moisture content within the by-product is high, current flows well, so the resistance value between the electrode sensors is low. On the other hand, if the moisture content within the by-product is low (dry), current does not flow well, so the resistance value between the electrode sensors is high. The moisture content of the by-product can be indirectly determined by the difference in these resistance values.

[0416] As another example, the moisture content detection sensor (1200) may include a capacitance sensor (372) that measures the dielectric constant of food in the decomposition tank (310) to calculate the dryness (or moisture content). The capacitance sensor (372) may be installed on the outer surface of the decomposition tank (310) to detect the moisture content of the byproduct in a non-contact manner.

[0417] The capacitance sensor (372) may include two capacitance sensors (372) with different sensitivities.

[0418] Since a high sensitivity capacitive sensor can detect low permittivity, it is designed to send a LOW signal when the by-product reaches a certain moisture content, and when this sensor signal is LOW, it is determined that the moisture content is low.

[0419] Since the low sensitivity capacitance sensor can detect high permittivity, it is designed to send a HIGH signal when the by-product exceeds a certain moisture content, and when this sensor signal is sent as HIGH, it can be determined that the internal state of the decomposition tank (310) is over-humidified.

[0420] The temperature sensor (1100) detects the temperature within the decomposition unit (300) and provides the temperature to the control unit (1800). The temperature sensor (1100) may be installed in the decomposition tank (310) to detect the temperature within the decomposition tank (310).

[0421] The input port light (113) is placed on the input cover (111) to generate light. The input port light (113) may include an LED. The input port light (113) may display various colors to indicate whether the food waste disposer (1) is operating, whether there is a problem with the food waste disposer (1), and whether food can be input.

[0422] The control unit (1800) can be implemented with a processor or microcomputer, and communicates with various sensors and configurations in each module through wired or wireless communication to control the operation of each module accordingly.

[0423] For example, the control unit (1800) can determine the state within the decomposition unit (300) based on the moisture content input from the moisture content detection sensor (1200), and control the stirring motor (330) and heater (328) to perform an operation corresponding to the state within the decomposition unit.

[0424] In addition, the control unit (1800) can determine the state within the decomposition unit (300) based on the moisture content input from the moisture content detection sensor (1200), and control at least one of the stirring motor (330), heater (328), collection motor (450), inlet light (113), lower motor, exhaust fan (620), and display unit (14) to perform a process corresponding to the state within the decomposition unit. Accordingly, the control unit (1800) can optimally maintain the state of microorganisms within the decomposition unit (300).

[0425] In the decomposition tank (310), microorganisms capable of decomposing food materials in the decomposition tank (310) and excipients are placed together. These excipients and microorganisms exhibit a distinct tendency to decrease in the total bacterial count when the moisture content is 70% or higher, and the optimal condition for the total bacterial count is when the moisture content is 40-60%. The excipients can be selected from materials with a maximum moisture content of 72% to 75%.

[0426] Specifically, the control unit (1800) determines the state of the inside of the decomposition unit (300) as one of an over-moisture state, a medium-moisture state with a lower moisture content than the over-moisture state, and a low-moisture state with a lower moisture content than the medium-moisture state.

[0427] Here, the control unit (1800) can calculate the excess moisture content based on the maximum moisture content of the excipient entering the decomposition tank (310). The excess moisture content may be 90% to 95% of the maximum moisture content of the excipient. Accordingly, the excess moisture content may be 67% to 73%. Preferably, the excess moisture content may be 69% to 71%.

[0428] The control unit (1800) can determine the state of the decomposition unit (300) as an over-moisture state when the moisture content of the food is higher than the over-moisture content. Preferably, the control unit (1800) can determine the state as an over-moisture state when the moisture content of the food is 70% or higher.

[0429] The over-moisture condition is a condition in which the moisture content in the decomposition tank (310) is too high, resulting in low microbial activity. At this time, the control unit (1800) can execute a control (over-moisture treatment) to reduce the moisture content of the decomposition tank (310). This will be described later.

[0430] The control unit (1800) can calculate the medium moisture content based on the maximum moisture content of the excipient entering the decomposition tank (310). The medium moisture content may be 40% to 95% of the maximum moisture content of the excipient. Accordingly, the medium moisture content may be 30% to 70%. Preferably, the medium moisture content may be 35% to 65%.

[0431] The control unit (1800) can determine the state of the decomposition unit (300) as a medium moisture state when the moisture content of the food is within the medium moisture content range. Preferably, the control unit (1800) can determine the state as a medium moisture state when the moisture content of the food is between 30% and 68%.

[0432] The medium moisture state is a state in which the moisture content in the decomposition tank (310) is appropriate and microbial activity is excellent. At this time, the control unit (1800) can execute control (decomposition and drying process) to dry and decompose food in the decomposition tank (310). This will be described later.

[0433] The control unit (1800) can calculate the low moisture content based on the maximum moisture content of the excipient entering the decomposition tank (310). The low moisture content may be 40% of the maximum moisture content of the excipient. Accordingly, the low moisture content may be 27% to 32%. Preferably, the low moisture content may be 28% to 31%.

[0434] The control unit (1800) can determine the state of the decomposition unit (300) as a low moisture state when the moisture content of the food is lower than the low moisture content. Preferably, the control unit (1800) can determine the state as a low moisture state when the moisture content of the food is less than 30%.

[0435] The low-moisture state is a state in which the moisture content in the decomposition tank (310) is low, so that the food is well decomposed and dried. At this time, the control unit (1800) can execute a control (collection and storage process) to store the food in the decomposition tank (310) and transfer it to the transfer unit. This will be described later.

[0436] Specifically, the control unit (1800) can execute a super-humidification process to reduce moisture within the decomposition unit (300) in an over-moisture state. The control unit (1800) can increase the rotation frequency of the stirring motor (330) in an over-moisture state and raise the temperature within the decomposition tank (310).

[0437] More specifically, if the control unit (1800) determines that the state inside the decomposition unit (300) is an over-moisture state, the control unit (1800) controls the stirring motor (330) to rotate for a first time period and stop for a second time period shorter than the first time period, and controls the heater (328) to maintain the decomposition unit (300) in a first temperature range (high temperature).

[0438] The control unit (1800) may rotate the stirring motor (330) for a first time period, stop for a second time period, and then rotate it again for the first time period in a direction opposite to the previous rotation direction.

[0439] In addition, the control unit (1800) can execute a decomposition and drying process to dry and decompose food within the decomposition unit (300) in a medium moisture state. The control unit (1800) can maintain the rotation frequency of the stirring motor (330) at an intermediate level in a medium moisture state and maintain the temperature within the decomposition tank (310) at an intermediate temperature.

[0440] Specifically, if the control unit (1800) determines that the state of the inside of the decomposition unit (300) is a medium moisture state, the control unit (1800) controls the stirring motor (330) to rotate for a third time and stop for a fourth time shorter than the third time, and controls the heater (328) to maintain the decomposition unit (300) in the second temperature range.

[0441] The first time period may be longer than the third time period, and the second time period may be shorter than the fourth time period. The middle temperature of the first temperature range may be higher than the middle temperature of the second temperature range. Therefore, in the over-moisture state, the stirring motor (330) rotates at a higher frequency than in the medium-moisture state, and the temperature of the decomposition tank (310) in the over-moisture state may be higher than the temperature of the decomposition tank (310) in the medium-moisture state.

[0442] Preferably, the first time period may be 28 seconds, the second time period may be 3 seconds, the third time period may be 25 seconds, and the fourth time period may be 6 seconds. The first temperature range may be 40 °C to 45 °C, and the second temperature range may be 32 °C to 39 °C.

[0443] Additionally, the control unit (1800) can execute a storage and transport operation to store food in the decomposition unit (300) in a low moisture state. The control unit (1800) can keep the rotation frequency of the stirring motor (330) low in the low moisture state and turn off the heater (328) of the decomposition tank (310).

[0444] Specifically, if the control unit (1800) determines that the state of the inside of the decomposition unit (300) is a low moisture state, it can control the stirring motor (330) to rotate for a fifth time and stop for a sixth time that is longer than the fifth time, and turn off the heater (328).

[0445] The first hour can be longer than the third hour, and the third hour can be longer than the fifth hour. The fifth hour can be 13 seconds.

[0446] The second time period may be shorter than the fourth time period, and the fourth time period may be shorter than the sixth time period. The sixth time period may be 40 to 50 seconds. The sixth time period may be longer than the first to fifth time periods.

[0447] The food waste disposer (1) of the present disclosure may further include an exhaust fan (620) disposed in a path for discharging air within the decomposition unit (300).

[0448] The control unit (1800) controls the speed of the exhaust fan (620) according to the state of the decomposition unit (300), thereby discharging moisture inside the decomposition unit (300) to the outside, thereby allowing the humidity inside the decomposition unit (300) to be controlled more quickly.

[0449] Specifically, if the control unit (1800) determines that the state inside the decomposition unit (300) is an over-moisture state, it can rotate the exhaust fan (620) at a first speed, and if it determines that the state inside the decomposition unit (300) is an intermediate moisture state, it can rotate the exhaust fan (620) at a second speed lower than the first speed.

[0450] In addition, if the control unit (1800) determines that the state inside the decomposition unit (300) is a low moisture state, the exhaust fan (620) can rotate at a second speed. Of course, if the control unit (1800) determines that the state inside the decomposition unit (300) is a low moisture state, the exhaust fan (620) can rotate at a third speed lower than the second speed, or stop the exhaust fan (620).

[0451] In addition, if the control unit (1800) determines that the state inside the decomposition unit (300) is a low moisture state, it can operate the transport unit to transport the food in the decomposition unit (300) to the collection unit (500). Specifically, the control unit (1800) rotates the collection motor (450) to transport the dried food in the decomposition tank (310) to the collection unit (500).

[0452] Of course, if the control unit (1800) determines that the moisture content is low, it can output a message indicating that the drying of the food is complete through the display unit (14) or / and the terminal.

[0453] In addition, the control unit (1800) can output the state of microorganisms inside the decomposition unit (300) through an image or / and text via the display unit (14) or / and a terminal.

[0454] If the control unit (1800) determines that the moisture content is low, it can output an image or / and text through the display unit (14) or / and the terminal to indicate that the microbial condition is good.

[0455] If the control unit (1800) determines that the condition of the microorganism is excessive, it can output the poor condition of the microorganism through an image or / and text via the display unit (14) or / and the terminal (Figs. 15 to 17).

[0456]

[0457] The control unit (1800) can output a control signal notifying of a processing abnormality if the state within the decomposition unit (300) remains in an over-moisture state for a period exceeding a reference time. Accordingly, the user can take appropriate measures if the state within the decomposition unit (300) remains in an over-moisture state for a long time.

[0458] Specifically, the control unit (1800) can control the display unit (14) to output an abnormal state of processing when the state inside the decomposition unit (300) remains in an over-moisture state for a period exceeding a reference time.

[0459] In addition, the control unit (1800) can control the processing unit (300) to output an abnormal state through the terminal if the state inside the decomposition unit (300) remains in an over-moisture state for a period exceeding a reference time.

[0460] In addition, the control unit (1800) can control to output an abnormal state of processing through the inlet light (113) if the state inside the decomposition unit (300) remains in an over-moisture state for a period exceeding a reference time. Specifically, if the state of processing is abnormal, the control unit (1800) can control to change the wavelength of the inlet light (113) or to turn it on and off repeatedly.

[0461] In addition, the control unit (1800) can control the food waste disposer (1) to prevent food from being fed through the inlet if the state inside the decomposition unit (300) remains in an over-moisture state for a period exceeding a standard time.

[0462] Specifically, the control unit (1800) can maintain the locked state of the cover locking unit (280) so that the inlet is not opened when the state inside the decomposition unit (300) remains in an over-moisture state for a period exceeding a reference time.

[0463] If the internal state of the decomposition unit (300) remains in an over-moisture state for a period exceeding a reference time, the control unit (1800) can maintain the lower locking unit (910) in an open state so that the decomposition unit (300) is separated from the main body.

[0464] If the control unit (1800) determines that the internal state of the decomposition unit (300) is in an over-moisture state, the lower locking unit (910) can be controlled to maintain a locked state that prevents the decomposition unit (300) from being separated from the main body. Since the decomposition tank (310) becomes hot in an over-moisture state, the decomposition unit (300) is prevented from being separated from the main body.

[0465] If the control unit (1800) determines that the internal state of the decomposition unit (300) is excessively moist, it can display through the display unit (14) that the decomposition unit (300) is at high temperature.

[0466]

[0467] Fig. 14 is a flowchart of a control method of a food waste disposer (1) according to one embodiment of the present disclosure.

[0468] Referring to FIG. 14, a method for controlling a food waste disposer (1) according to one embodiment of the present disclosure measures the moisture content of food inside a decomposition tank (310) (S10). Specifically, the control unit (1800) measures the moisture content of food inside the decomposition tank (310) by an electrode sensor (371) or / and a capacitance sensor (372).

[0469] Thereafter, the control unit (1800) determines the state of the decomposition unit (300) based on the moisture content (S20). Specifically, the control unit (1800) can determine the state within the decomposition unit (300) based on the moisture content input from the moisture content detection sensor (1200).

[0470] Specifically, if the control unit (1800) determines that the state of the inside of the decomposition unit (300) is an over-moisture state (S30), it can execute an over-moisture process (S40).

[0471] The over-moisture process is a process for quickly reducing moisture within the decomposition unit (300). Specifically, the control unit (1800) can increase the rotation frequency of the stirring motor (330) in the over-moisture state and raise the temperature within the decomposition tank (310).

[0472] More specifically, if the control unit (1800) determines that the state inside the decomposition unit (300) is an over-moisture state, the control unit (1800) can control the stirring motor (330) to rotate for a first time period and stop for a second time period shorter than the first time period, and control the heater (328) so that the decomposition unit (300) maintains a first temperature range (high temperature). If the control unit (1800) determines that the state inside the decomposition unit (300) is an over-moisture state, the control unit (1800) can control the exhaust fan (620) to rotate at a first speed. If the control unit (1800) determines that the state inside the decomposition unit (300) is an over-moisture state, the control unit (1800) can control the lower locking unit to maintain a locked state that prevents the decomposition unit (300) from being separated from the main body. Since the decomposition tank (310) becomes high temperature in the over-moisture state, the decomposition unit (300) is prevented from being separated from the main body.

[0473] If the control unit (1800) determines that the internal state of the decomposition unit (300) is excessively moist, it can display through the display unit (14) that the decomposition unit (300) is at high temperature.

[0474] Afterwards, if the over-watering state continues for a certain period of time (20 hours) or longer (S60), an abnormality in the processing state can be notified (S70).

[0475] Specifically, the control unit (1800) can control the display unit (14) to output an abnormal state of processing when the state inside the decomposition unit (300) remains in an over-moisture state for a period exceeding a reference time.

[0476] In addition, the control unit (1800) can control the processing unit (300) to output an abnormal state through the terminal if the state inside the decomposition unit (300) remains in an over-moisture state for a period exceeding a reference time.

[0477] In addition, the control unit (1800) can control to output an abnormal state of processing through the inlet light (113) if the state inside the decomposition unit (300) remains in an over-moisture state for a period exceeding a reference time. Specifically, if the state of processing is abnormal, the control unit (1800) can control to change the wavelength of the inlet light (113) or to turn it on and off repeatedly.

[0478] In addition, the control unit (1800) can control the food waste disposer (1) to prevent food from being fed through the inlet if the state inside the decomposition unit (300) remains in an over-moisture state for a period exceeding a standard time.

[0479] Specifically, the control unit (1800) can maintain the locked state of the cover locking unit (280) so that the inlet is not opened when the state inside the decomposition unit (300) remains in an over-moisture state for a period exceeding a reference time.

[0480] If the internal state of the decomposition unit (300) remains in an over-moisture state for a period exceeding a reference time, the control unit (1800) can maintain the lower locking unit in an open state so that the decomposition unit (300) is separated from the main body.

[0481] In addition, the control unit (1800) can control the solid-liquid separation unit not to operate if the internal state of the decomposition unit (300) remains in an over-moisture state for a period of time exceeding a reference time. Specifically, the control unit (1800) can stop the operation of the transport motor (220) if the internal state of the decomposition unit (300) remains in an over-moisture state for a period of time exceeding a reference time (S70).

[0482] If the control unit (1800) determines that the state of the decomposition unit (300) is a medium moisture state (S81), it executes the decomposition and drying process (S83). Specifically, if the control unit (1800) determines that the state inside the decomposition unit (300) is a medium moisture state, it controls the stirring motor (330) to rotate for a third time and stop for a fourth time shorter than the third time, and controls the heater (328) to maintain the decomposition unit (300) in a second temperature range.

[0483] If the control unit (1800) determines that the internal state of the decomposition unit (300) is a medium moisture state, it can rotate the exhaust fan (620) at a second speed.

[0484] If the control unit (1800) determines that the state of the decomposition unit (300) is a low moisture state (S91), it executes the decomposition and drying process (S93).

[0485] Specifically, the control unit (1800) can keep the rotation frequency of the stirring motor (330) low in a low moisture state and turn off the heater (328) of the decomposition tank (310).

[0486] Specifically, if the control unit (1800) determines that the state of the inside of the decomposition unit (300) is a low moisture state, it can control the stirring motor (330) to rotate for a fifth time and stop for a sixth time that is longer than the fifth time, and turn off the heater (328).

[0487] In addition, if the control unit (1800) determines that the state inside the decomposition unit (300) is a low moisture state, the exhaust fan (620) can rotate at a second speed. Of course, if the control unit (1800) determines that the state inside the decomposition unit (300) is a low moisture state, the exhaust fan (620) can rotate at a third speed lower than the second speed, or stop the exhaust fan (620).

[0488] In addition, if the control unit (1800) determines that the state inside the decomposition unit (300) is a low moisture state, it can operate the transport unit to transport the food in the decomposition unit (300) to the collection unit (500). Specifically, the control unit (1800) rotates the collection motor (450) to transport the dried food in the decomposition tank (310) to the collection unit (500).

[0489] Of course, if the control unit (1800) determines that the moisture content is low, it can output a message indicating that the drying of the food is complete through the display unit (14) or / and the terminal.

[0490]

[0491] FIG. 15 is a drawing illustrating a display unit according to one embodiment of the present disclosure.

[0492] Referring to FIG. 15, the display unit can display various states of the food waste disposer (1) according to the control signal of the control unit (1800).

[0498] The terminal (2000) can display various states of the food waste disposer (1) according to the control signal of the control unit (1800).

[0499] The control unit (1800) can output the state of microorganisms inside the decomposition unit (300) through an image or / and text via the terminal (2000).

[0500] Figure 16 illustrates displaying good microbial status on the terminal (2000) screen.

[0501] Referring to FIG. 16, if the control unit (1800) determines that the moisture content is low, it can output an image or / and text through the terminal (2000) indicating that the microbial condition is good.

[0502] Specifically, the terminal (2000) may include a user interface (2100) for exchanging information with a user. The user interface (2100) may include at least one of an image display unit (2110) for visually displaying the state of a microorganism, a text information display unit (2140) for displaying the state of a microorganism in letters and symbols, and a predicted lifespan display unit (2130) for displaying the predicted lifespan of a microorganism based on the state of the microorganism.

[0503] Additionally, the user interface (2100) may include a management guide execution unit (2130) that allows the user to check detailed information on a method for managing microorganisms.

[0504] The image display unit (2110) can display a character image of a microorganism, and can indicate the state of the microorganism by the color of the image and the expression of the character. Specifically, if the state of the microorganism is good, the image display unit (2110) can display the color of the image as green or blue, and the expression of the character as smiling or bright.

[0505] When a user's command is input through the management guide execution unit (2130), the user interface (2100) can output a management method corresponding to the state of the microorganism.
