[0034] The aforementioned objectives, features, and advantages are described in detail below with reference to the attached drawings, thereby enabling those skilled in the art to easily implement the technical concept of the present invention. In describing the present invention, detailed descriptions of known technologies related to the present invention are omitted if it is determined that such descriptions would unnecessarily obscure the essence of the invention. Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings. In the drawings, the same reference numerals are used to indicate the same or similar components.

[0035] [Overall configuration of the individually sealed food waste disposal device]

[0036] FIG. 1 is a perspective view showing the state in which an individual sealed food waste disposal device (1) according to one embodiment of the present invention is installed on a refrigerator door (410); FIG. 2 and FIG. 3 are perspective views showing the individual sealed food waste disposal device (1) according to one embodiment of the present invention; and FIG. 4 is an exploded perspective view of the individual sealed food waste disposal device (1) according to one embodiment of the present invention.

[0037] As illustrated in FIGS. 1 to 4, an individual sealed food waste disposal device (1) according to one embodiment of the present invention seals a small amount of food waste (600) contained in a bag (500) and stores it in a frozen state inside a case part (10). Since a plurality of bags (500) stored frozen inside the case part (10) are discharged simultaneously, the storage and discharge of food waste (600) can be easily performed.

[0038] A height adjustment unit (700) is installed on the inner side of the case unit (10), and a bag (500) for holding food waste (600) is installed on the upper side of the height adjustment unit (700). The height adjustment unit (700) is operated by a control signal from the control unit (310), and the height of the movable support unit (710) supporting the bag (500) is adjusted by the operation of the driving unit (740).

[0039] Therefore, when there is no sealed bag (500), the movable support (710) moves upward and is positioned below the sealing drive unit (200). Then, when the number of sealed bags (500) increases, the movable support (710) moves downward to form a space for loading food waste (600).

[0040] A door section (100) is installed on the upper side of a case section (10) that forms a space for storing food waste (600). The door section (100) includes a first door section (110) that opens and closes the upper part of the case section (10), and a second door section (130) that is rotatably installed on the inside of the first door section (110). The first door section (110) is opened when discarding a bag (500) containing food waste (600), and the second door section (130) is opened when discarding food waste (600) on the inside of the case section (10).

[0041] A sterilization unit (140) for sterilizing bacteria by irradiating light is installed in the door unit (100) or case unit (10). Various sterilization methods can be applied to the sterilization unit (140), such as using ozone generation in addition to irradiating light.

[0042] A bag supply unit (150) and a sealing drive unit (200) are each installed in the door unit (100). A raw material (170) that serves as the material for the bag (500) is supplied through the bag supply unit (150), and the sealing drive unit (200) is operated to seal the raw material (170) at a set position or to cut between the raw material (170) and the bag (500).

[0043] By the operation of the drive motor (210) provided in the sealed drive unit (200), the first heating unit (270) and the second heating unit (275) constituting the heater unit (260) come together in the center to seal the plastic bag (500).

[0044] In addition, the individual sealed food waste treatment device (1) according to the present invention can hygienically treat food waste (600) by dividing it into smaller portions, sealing them, and storing them in a frozen state.

[0045] An individual sealed food waste treatment device (1) according to one embodiment of the present invention may include at least one of a case part (10), a door part (100), a sterilization part (140), a bag supply part (150), a sealing drive part (200), a sealing part (280), a blower fan (290), a damper part (300), a control part (310), a battery (320), and a height adjustment part (700).

[0046] In the present invention, a case part (10) and a door part (100) are combined to form the outer shape of an individually sealed food waste treatment device (1). The case part (10) has an open upper side to form an inlet part (32), and a door part (100) connected to the case part (10) opens and closes the inlet part (32).

[0047] The user opens the door (100) and puts food waste (600) into the bag (500) located inside the case (10). Then, with the door (100) closed, the case (10) is positioned inside the refrigerator (400). The case (10) can be installed on the freezer door of the refrigerator (400), and various modifications are possible, such as being installed on the inner shelf of the freezer if necessary.

[0048] The food waste (600) inside the case part (10) is frozen by the cold air of the freezer.

[0049] The door section (100) for opening and closing the case section (10) may be a single door, or it may be a double door to facilitate the operation of disposing of food waste (600). When the door section (100) is a double door, the door section (100) includes a first door section (110) and a second door section (130).

[0050] The first door section (110) is rotatably installed in the case section (10), and the second door section (130) is rotatably installed on the inside of the first door section (110). Therefore, when food waste (600) is put into a bag (500) located on the inside of the case section (10), the second door section (130) can be opened and the food waste (600) can be disposed of in the bag (500).

[0051] And, when the bag (500) is completely filled with food waste (600), after the bag (500) is automatically sealed, the first door section (110) can be opened and the bag (500) filled with food waste (600) can be easily removed to the outside of the case section (10).

[0052] A sterilization unit (140) is installed in the door unit (100) to irradiate a sterilization light toward the inside of the case unit (10). Since the operation of the sterilization unit (140) stops when the second door unit (130) is opened, it is possible to block the transmission of a sterilization light harmful to the human body to the user.

[0053] A bag supply unit (150) for supplying a bag (500) to the inside of the case unit (10) is installed in the door unit (100). A fabric member (170) made of vinyl is installed inside the bag supply unit (150), and the fabric member (170) drawn out to the outside of the bag supply unit (150) unfolds to the inside of the case unit (10) to form a bag (500).

[0054] A sealing drive unit (200) is installed in succession to the envelope supply unit (150), and a heater unit (260) equipped with a heating wire heats and cuts a fabric member (170) that extends to the lower side of the envelope supply unit (150). In addition, since the lower side of the fabric member (170) supplied through the envelope supply unit (150) is sealed by heat fusion by the heater unit (260) of the sealing drive unit (200), the supply of the envelope (500) can be performed automatically.

[0055] And, since the lower side of the fabric member (170) located on the upper side of the sealing drive unit (200) is also sealed by heat fusion, the lower side of the envelope (500) newly supplied to the inside of the case unit (10) can be supplied in a state sealed by heat fusion.

[0056] A blower fan (290) is installed on the lower side of the case section (10) and discharges air inside the case section (10) to the outside of the case section (10). Accordingly, a newly supplied envelope (500), which has its lower side sealed by the operation of the sealing drive unit (200), is moved to the lower side of the case section (10) by the operation of the blower fan (290).

[0057] Air passing through the blower fan (290) is discharged to the lower side of the case section (10), and a separate damper section (300) is installed at the outlet of the blower fan (290) to control the discharge and suction of air. The damper section (300) allows the discharge of air toward the outside of the case section (10) and blocks the movement of air toward the inside of the case section (10). A plastic bag (500) is unfolded toward the inside of the case section (10) and adheres to the inside of the case section (10), and the blower fan (290) is installed at the lower side of the case section (10) to prevent contamination of the blower fan (290).

[0058] Additionally, the case section (10) is made of a double structure, and a blower fan (290), a control section (310), a battery (320), and a damper section (300) may be installed between the outer case (20) and the inner case (30). Since the blower fan (290), the control section (310), the battery (320), and the damper section (300) are not located inside the inner case (30), interference with the frozen food waste (600) is prevented when the food waste (600) is frozen inside the bag (500). Therefore, when the bag (500) is taken out to the outside of the case section (10) along with the frozen food waste (600), the food waste (600) can be easily discharged.

[0059] A height adjustment unit (700) is installed on the lower side of the sealing drive unit (200). The height adjustment unit (700) is installed on the inner bottom surface of the case unit (10) and is operated by the control unit (310) to adjust the height supporting the envelope (500).

[0060] The height adjustment unit (700) is equipped with an adjustment motor (742) that operates under the control of the control unit (310). Since the height of the movable support unit (710) provided in the height adjustment unit (700) is adjusted by the operation of the adjustment motor (742), the support height of the envelope (500) is varied.

[0061] The individual sealed food waste treatment device (1) according to the present invention sets the storage amount of food waste (600) contained in the bag (500) to be small, and seals the upper side of the bag (500) containing the set amount of food waste (600). Then, after lowering the movable support member (710) considering the volume of the sealed bag (500), a new bag (500) is supplied again to the upper side of the sealed bag (500).

[0062] When the sealing drive unit (200) stores bags (500) containing food waste (600) in succession after sealing them, it controls the temperature of the heater unit (260) to prevent the bags (500) and adjacent bags (500) from being cut.

[0063] In preparation for cases where the envelope (500) is stored in storage mode and where the envelope (500) is discharged in discharge mode, the control unit (310) controls the operation of the sealing drive unit (200) and the height adjustment unit (700). Additionally, the control unit (310) receives measurement values ​​from the measurement unit (800) and the door sensor unit (810) to control the operation of the sealing drive unit (200) and the height adjustment unit (700) more precisely.

[0064] [refrigerator]

[0065] The individual sealed food waste disposal device (1) is located inside the refrigerator (400) or freezer and can be used independently if necessary. The individual sealed food waste disposal device (1) according to one embodiment of the present invention is detachably installed on the refrigerator door (410) that opens and closes the freezer compartment of the refrigerator (400) or on the shelf of the freezer compartment.

[0066] When an individual sealed food waste disposal device (1) is installed on a refrigerator door (410), a separate support shelf (411) may be separately provided on the refrigerator door (410) to support the lower part of the individual sealed food waste disposal device (1). The individual sealed food waste disposal device (1) is located on the upper side of the support shelf (411) and slides along the support shelf (411). The individual sealed food waste disposal device (1), which has moved horizontally along the support shelf (411), can be separated from the support shelf (411) and used independently.

[0067] Meanwhile, when the individual sealed food waste disposal device (1) is installed on the shelf of the freezer, a separate device to restrict the movement of the individual sealed food waste disposal device (1) may also be additionally provided on the freezer shelf.

[0068] [Case Section]

[0069] The case section (10) is provided with an internal space for storing food waste (600) and is installed so as to be detachably attached to the refrigerator (400). An entrance section (32), which is a space for withdrawing a bag (500), is provided on the upper side of the case section (10).

[0070] Food waste (600) is stored inside the bag (500) while the bag (500) is unfolded inside the case section (10). Then, the food waste (600) is frozen by the operation of storing the case section (10) in the freezer. The case section (10) is installed in the freezer equipped in the refrigerator (400), and can be separated from the refrigerator (400) and used independently as needed, thereby further improving convenience of use.

[0071] For example, the refrigerator door (410) can be opened, and the door portion (100) provided in the individual sealed food waste disposal device (1) can be opened, and the food waste (600) can be put into the inside of the case portion (10). Alternatively, the case portion (10) can be separated from the refrigerator (400), placed on a sink or the like, and the door portion (100) can be opened to put the food waste (600) into the inside of the case portion (10). In this way, the food waste (600) can be processed in various ways according to the user's needs, and since the food waste (600) contained in the case portion (10) is frozen, the time and cost required for the food waste (600) processing work can be reduced.

[0072] The case part (10) can be implemented in various modifications within the technical concept of being detachably installed on the freezer door of the refrigerator (400). The case part (10) according to one embodiment of the present invention may include at least one of an outer case (20), an inner case (30), a rail projection (40), a handle part (50), and a monitor part (60).

[0073] The outer case (20) forms the outer shape of the case part (10) and has a shape with an open upper side. The outer case (20) according to one embodiment of the present invention is formed in a cuboid shape with an open upper side. However, the outer case (20) can be modified into other shapes, including a cylindrical shape.

[0074] The inner case (30) is located on the inner side of the outer case (20) and has an inner space for the envelope (500) to unfold. A space is formed between the inner case (30) and the outer case (20). Thus, a blower fan (290), a damper unit (300), a control unit (310), and a battery (320) can be installed between the inner case (30) and the outer case (20).

[0075] Food waste (600) inside the inner case (30) is frozen inside the bag (500), and if there is a protruding part in contact with the bag (500), it may be frozen together with the bag (500), so difficulty may occur in the operation of withdrawing the bag (500).

[0076] Alternatively, when food waste (600) stored inside the bag (500) is moved to the outside of the case part (10) together with the bag (500) while frozen, the frozen food waste (600) may get caught on a part protruding into the inner case (30), causing difficulty in the extraction of the bag (500).

[0077] Therefore, components such as the blower fan (290), damper unit (300), control unit (310), and battery (320) are installed in the space provided between the inner case (30) and the outer case (20), so that the discharge of the bag (500) along with the frozen food waste (600) can be easily performed.

[0078] A blower fan (290) is located between the outer case (20) and the inner case (30), the inlet of the blower fan (290) is connected to the blower hole (33), and the outlet of the blower fan (290) is connected to the outside of the outer case (20).

[0079] In addition, a blower hole (33) is provided on the lower side of the inner case (30), and a blower fan (290) is installed at a position facing the blower hole (33). When the blower fan (290) is operated, air inside the inner case (30) is discharged to the outside of the case part (10) through the blower hole (33).

[0080] The rail projection (40) protrudes downward from the outer case (20) and is inserted into the rail groove provided in the refrigerator door (410), thereby guiding the linear movement of the outer case (20). The rail projection (40) is installed on each side in the width direction (W) of the outer case (20) and protrudes downward from the outer case (20). The rail projection (40) is a projection protruding in the shape of a rectangular parallelepiped and is inserted into the support shelf (411) provided in the refrigerator door (410) to slide.

[0081] Accordingly, when an individual sealed food waste disposal device (1) is installed on the refrigerator door (410), the user can slide the individual sealed food waste disposal device (1) horizontally, open the door (100), and put food waste (600) into the inside of the case (10).

[0082] The handle portion (50) protrudes outward from the outer case (20) and is grasped by the user's hand. Therefore, the user can easily move the individually sealed food waste disposal device (1) by holding the handle portion (50).

[0083] The monitor unit (60) can be implemented in various modifications within the technical concept of checking the usage status of the bag (500) located inside the case unit (10). In one embodiment of the present invention, the monitor unit (60) has a transparent window (62) installed in the case unit (10) in the vertical direction. Therefore, the user can easily know the storage height of the food waste (600) through the transparent window (62).

[0084] In other embodiments of the present invention, various modifications are possible, such as installing a separate sensor to automatically measure the storage height of food waste (600) and notify the user.

[0087] As illustrated in FIGS. 5 and 6, the door section (100) is composed of double doors and opens and closes the upper side of the case section (10). Additionally, the door section (100) is rotatably connected to the case section (10), and various modifications are possible within the technical concept of opening and closing the entrance section (32) of the case section (10). The door section (100) according to the present invention is composed of a plurality of doors, and a door used for disposing of food waste (600) and a door used for disposing of frozen food waste (600) may be separately provided. The door section (100) according to one embodiment of the present invention includes a first door section (110) and a second door section (130).

[0088] The first door part (110) is rotatably installed on the case part (10) and opens and closes the entrance part (32). The first door part (110) is rotatably installed on the outer case (20) and opens and closes the upper side of the case part (10). The first door part (110) according to one embodiment of the present invention is installed in the shape of a square frame and has an inner insertion part (112) which is a hole penetrating in the vertical direction on the inside.

[0089] An inner support member (114) is installed along the inner perimeter of the first door section (110) facing the inner input section (112). The inner support member (114) supports the lower part of the bag supply section (150) and is installed in the shape of a square frame. Accordingly, the bag supply section (150) is installed on the inner side of the first door section (110), and the inner input section (112), which is a space for disposing of food waste (600), is located on the inner side of the bag supply section (150).

[0090] The second door section (130) is installed on the first door section (110) and opens and closes the inner insertion section (112) that penetrates the first door section (110) in the vertical direction. The second door section (130) is located above the envelope supply section (150) and is rotatably installed on the first door section (110). Accordingly, the inner insertion section (112) is opened and closed by the rotational movement of the second door section (130).

[0091] A door section (100) according to one embodiment of the present invention is divided into a first door section (110) used for disposing of food waste (600) and a second door section (130) used for collecting food waste (600). Therefore, since the second door section (130), which is smaller in size than the first door section (110), can be opened to dispose of the food waste (600), the task of disposing of the food waste (600) can be performed conveniently. In addition, when disposing of frozen food waste (600) together with a bag (500), the first door section (110) is opened to perform the disposal task, so the task of disposing of the food waste (600) is also performed conveniently.

[0092] Although it has been described that the first door section (110) and the second door section (130) are opened and closed by a rotating motion, this is not limited thereto, and the opening and closing motion can be performed in various ways, including a sliding method.

[0093] A bag supply unit (150) that supplies a bag (500) and a sealing drive unit (200) that cuts and seals the bag (500) are installed in the door unit (100). Therefore, since the bag supply unit (150) and the sealing drive unit (200) rotate together with the door unit (100), the collection of the bag (500) is easily performed, and maintenance of the bag supply unit (150) and the sealing drive unit (200) can be easily performed.

[0094] The envelope supply unit (150) and the sealing drive unit (200) are not installed in a position that interferes with the inner input unit (112) and are installed on the inner side of the first door unit (110). Since the sealing drive unit (200) is located below the envelope supply unit (150), the cutting and sealing of the raw material member (170) drawn out to the lower side of the envelope supply unit (150) can be easily performed. The raw material member (170) is a material for making an envelope (500), and vinyl or the like can be used as the raw material member (170).

[0095] Meanwhile, the second door section (130) can be opened to facilitate replacement and maintenance work on the envelope supply section (150). Since the envelope supply section (150) is installed on the lower side of the second door section (130), the upper side of the envelope supply section (150) is opened when the second door section (130) is rotated upward. Therefore, when the material material (170) stored inside the envelope supply section (150) is depleted, the user can take out the envelope supply section (150) from the door section (100) and resupply the material material (170).

[0096] [Sterilization Section]

[0097] The sterilization unit (140) is installed in the second door unit (130), and various modifications can be implemented within the technical concept of irradiating a sterilization light toward the inside of the case unit (10). The sterilization unit (140) operates only when the second door unit (130) is closed and irradiates a sterilization light toward the inside of the case unit (10) into which food waste (600) is introduced.

[0098] The sterilization light irradiates ultraviolet rays, which are invisible radiation with a shorter wavelength than the visible violet light. Ultraviolet A (UVA) has a wavelength range of 315 to 380 nanometers (nm), ultraviolet B (UVB) has a wavelength range of 280 to 315 nanometers (nm), and ultraviolet C (UVC) has a wavelength range of 100 to 280 nanometers (nm). The sterilization unit (140) according to the present invention uses an LED that irradiates UVC, which has an excellent sterilization effect.

[0099] Since the sterilization unit (140) uses an ultraviolet LED with a lifespan of 30,000 hours or more, the operational safety of the sterilization unit (140) can be ensured. Additionally, the sterilization unit (140) can use an ultraviolet LED that outputs light with a sterilization wavelength of 270 to 280 nm alone. Alternatively, since an ultraviolet LED that outputs light with a sterilization wavelength of 270 to 280 nm is used together with an ultraviolet LED that outputs light with a wavelength of 365 nm, which is effective for reaction with titanium dioxide (TiO2), a photocatalyst, ozone is not generated.

[0100] [Envelope Supply Unit]

[0101] FIG. 7 is a perspective view illustrating a bag supply unit (150) and a sealing drive unit (200) according to one embodiment of the present invention.

[0102] As illustrated in FIGS. 4 and 7, the bag supply unit (150) is installed in the door unit (100), and various modifications are possible within the technical concept of supplying a bag (500) for containing food waste (600) into the inside of the case unit (10). The bag supply unit (150) according to one embodiment of the present invention is installed in the door unit (100) together with a sealing drive unit (200). The bag supply unit (150) according to one embodiment of the present invention includes a storage frame (160) and a discharge supply unit (180).

[0103] A storage frame (160) is mounted on a door portion (100) connected to a case portion (10) and installed along the perimeter of an inner input portion (112) through which food waste (600) is moved. A fabric material (170) for making a bag (500) is stored inside the storage frame (160).

[0104] A storage frame (160) according to one embodiment of the present invention is installed in a polygonal, circular, or elliptical shape using a pipe or a square tube, and the inner side of the storage frame (160) is interconnected so that the fabric member (170) is integrally connected. The center of the storage frame (160) is connected to an inner input section (112), which is a space for moving food waste (600). The storage frame (160) is provided with a space for storing the fabric member (170) on the inner side, such as an elliptical or polygonal shape, and various modifications are possible within the technical concept of extending in a strip shape.

[0105] A storage frame (160) according to one embodiment of the present invention is formed in the shape of a square frame, and the inner side of the storage frame (160) is provided with a hollow extending in the vertical direction. The cross-section of the storage frame (160) is in the shape of a square tube, and a space for storing a fabric member (170) is provided on the inner side.

[0106] The shape of the storage frame (160) is not limited to a square frame, and various modifications are possible, such as installing a pipe with a circular cross-section in a circular or elliptical shape as needed.

[0107] The hollow space provided on the inner side of the storage frame (160) is connected in the vertical direction to the inner input section (112) of the door section (100). Accordingly, food waste (600) that falls into the hollow space of the storage frame (160) after opening the second door section (130) passes through the inner input section (112) of the door section (100) and falls into the inner side of the bag (500) located on the lower side.

[0108] The fabric member (170) may be made of various materials within the technical concept of forming a bag (500) for holding food waste (600). In one embodiment of the present invention, a plastic film for holding food waste (600) may be used as the fabric member (170). The fabric member (170) is a tube-shaped cylindrical plastic film, with the upper and lower sides open.

[0109] The material of the fabric member (170) according to another embodiment of the present invention may be manufactured using a vinyl sheet containing calcium carbonate so that it can decompose by moisture. The fabric member (170) containing calcium carbonate is formed by mixing calcium carbonate powder with a synthetic resin (PE) having a certain tensile strength and density, thereby improving biodegradability.

[0110] A fabric member (170) according to another embodiment of the present invention is manufactured by incorporating plant components or biological materials into a resin to facilitate decomposition when landfilled. A fabric member (170) according to another embodiment of the present invention is made of a biodegradable material. The fabric member (170) may use a natural polymer-based vinyl that incorporates various plant components, such as biodegradable starch, corn flour, or soybean flour, into the resin. Alternatively, biodegradable vinyl may be used, such as a microbial synthesis system utilizing biopolymers or a chemical synthesis system that replaces a part of the molecular structure.

[0111] A bag (500) made of a fabric member (170) made of a biodegradable material has an improved decomposition speed and decomposition rate compared to conventional vinyl. Additionally, natural fermentation can be induced by adsorbing beneficial microorganisms that induce aerobic and anaerobic fermentation on the inside or outside of the fabric member (170).

[0112] The fabric member (170), which is made in various ways as described above, is a cylindrical envelope (500) with the upper and lower sides open, and is stored in a folded state inside the storage frame (160). The fabric member (170) is folded in a zigzag shape and positioned inside the storage frame (160).

[0113] The discharge supply unit (180) forms a hole for discharging a fabric member (170) in a storage frame (160) facing the inner input unit (112). The discharge supply unit (180) is provided with a narrow gap-shaped hole that is installed continuously along the inner circumference of the storage frame (160).

[0114] The discharge supply unit (180) is located on the side of the storage frame (160) facing the inner input unit (112) and forms a strip-shaped groove along the inner circumference of the storage frame (160). Accordingly, the fabric member (170) is drawn out through the discharge supply unit (180) and extends to the lower side of the storage frame (160).

[0115] The envelope supply unit (150) provides a structure in which a vinyl material material (170) is discharged from the upper side of the case unit (10). Since the material material (170) drawn out through the discharge supply unit (180) provided in the envelope supply unit (150) is installed in a shape that bends downward, the material material (170) provided inside the envelope supply unit (150) is prevented from unraveling downward.

[0116] [envelope]

[0117] The fabric member (170) extended downward through the discharge supply unit (180) has its lower side open, and the lower side of the fabric member (170) is sealed by heat fusion by the operation of the sealing drive unit (200) to form an envelope (500).

[0118] The bag (500) is provided with an inner space for holding food waste (600). The bag (500) is placed inside the case part (10), and the lower side of the bag (500) is closed while the upper side is open. Additionally, the upper side of the bag (500) placed in the case part (10) is connected to the fabric member (170).

[0119] The bag (500) can be made from a fabric material (170) supplied through the bag supply unit (150), and various modifications can be implemented, such as allowing the user to directly insert the bag (500) for food waste (600) into the inside of the case unit (10) as needed.

[0120] [Sealed drive unit]

[0121] FIG. 8 is a perspective view showing the state in which a sealing drive unit (200) according to one embodiment of the present invention is installed in a door unit (100), and FIG. 9 is a cross-sectional view showing the state in which a sealing drive unit (200) according to one embodiment of the present invention is installed in a door unit (100).

[0122] As illustrated in FIGS. 8 and 9, the sealing drive unit (200) is installed in the case unit (10) or door unit (100), and various modifications can be implemented within the technical concept of shielding or cutting the opening of the bag (500) containing food waste (600).

[0123] By operating the sealing drive unit (200), a bag (500) containing food waste (600) is sealed in a small quantity and frozen for storage. Additionally, multiple sealed bags (500) are discharged to the outside of the case unit (10), thereby preventing the decay and odor generation of the food waste (600).

[0124] The present invention is a device that helps a user store and dispose of food waste (600) more hygienically. An individual sealed food waste disposal device (1) according to one embodiment of the present invention can store food waste (600) hygienically by sealing a bag (500) in a small capacity.

[0125] The sealing drive unit (200) cuts the bag (500) containing food waste (600) and the fabric member (170) by heat, as the heated heater unit (260) moves and presses the lateral side of the fabric member (170) extended in the vertical direction from both sides. Additionally, the lower side of the fabric member (170) located above the heater unit (260) is sealed by the heater unit (260). Furthermore, the upper side of the bag (500) located below the heater unit (260) is also sealed by the heater unit (260).

[0126] When food waste (600) is filled into the bag (500), the sealing drive unit (200) is operated so that the sealing operation of the bag (500) is performed automatically, thereby preventing contamination caused by the user coming into contact with the food waste (600).

[0127] In addition, by operating the sealing drive unit (200), the operation of sealing the bag (500) filled with food waste (600) and sealing the bottom of the newly supplied bag (500) is performed automatically, thereby saving time required for collecting and reinstalling the bag (500). The sealing drive unit (200) according to one embodiment of the present invention includes a drive motor (210), an operating gear unit (220), and a heater unit (260).

[0128] In addition, to prevent the first heating unit (270) and the second heating unit (275) from moving in a tilted shape when the first heating unit (270) and the second heating unit (275) are moved, a guide structure is applied to the door unit (100) and the sealing drive unit (200), respectively.

[0129] [Drive Motor]

[0130] The drive motor (210) is fixed to the case part (10) or the door part (100) connected to the case part (10) and supplies rotational power. The drive motor (210) is operated by the control of the control part (310) and is installed on the inside of the door part (100). The drive motor (210) is installed on the inside of the first door part (110), and the operation gear part (220) is operated by the operation of the drive motor (210).

[0131] The drive motor (210) may be a servo motor or a stepper motor. Alternatively, various modifications are possible, such as using a motor combined with an encoder as the drive motor (210). The drive motor (210) according to the first embodiment of the present invention consists of a single motor and is installed at a position facing the point where the envelope (500) is cut.

[0132] [Operating Gear Section]

[0133] The operating gear unit (220) receives power from the driving motor (210) and moves a plurality of moving gears toward the center of the bag supply unit (150) or in a direction away from the center of the bag supply unit (150). Additionally, the operating gear unit (220) can be implemented in various variations within the technical concept of receiving power from the driving motor (210) to move the heater unit (260) located on both sides of the bag (500). The operating gear unit (220) according to one embodiment of the present invention may include a rotating gear (230), a first spur gear (240), a first moving block (245), a second spur gear (250), and a second moving block (255). The moving gear provided in the operating gear section (220) may be at least one of a rotating gear (230), a first spur gear (240), a first moving block (245), a second spur gear (250), and a second moving block (255).

[0134] The rotary gear (230) is connected to an output shaft (231) connected to a drive motor (210). The output shaft (231) of the rotary gear (230) is installed horizontally, and the rotary gear (230) is fixed to the outside of the output shaft (231). Thus, the rotary gear (230) rotates together with the output shaft (231).

[0135] The first spur gear (240) meshes with the upper side of the rotating gear (230) and moves horizontally by the rotation of the rotating gear (230). The first spur gear (240) extends in a rod shape, and a spur gear is provided on the lower side of the first spur gear (240). Since the first spur gear (240) is meshed with the rotating gear (230), the first spur gear (240) moves horizontally by the rotation of the rotating gear (230). The first spur gear (240) and the rotating gear (230) are made of rack and pinion gears, so rotational power is converted into linear movement.

[0136] The first spur gear (240) can be guided to move in a straight direction by a separate guide structure provided on the inner side of the door part (100).

[0137] The first moving block (245) is connected to the first spur gear (240), and a heater part (260) is installed on the side. The first moving block (245) is installed in a direction that intersects the first spur gear (240). Since the first moving block (245) is fixed to the first spur gear (240), it moves together with the first spur gear (240). The first moving block (245) is located on the lower side of the envelope supply part (150) and is installed on one side of the inner insertion part (112).

[0138] The second spur gear (250) meshes with the lower side of the rotating gear (230) and moves horizontally by the rotation of the rotating gear (230). The second spur gear (250) extends in a rod shape, and a spur gear is provided on the upper side of the second spur gear (250). Since the second spur gear (250) is meshed with the rotating gear (230), the second spur gear (250) moves horizontally by the rotation of the rotating gear (230).

[0139] The second moving block (255) is connected to the second spur gear (250), and a heater part (260) is installed on the side. The second moving block (255) is installed in a direction that intersects the second spur gear (250). Since the second moving block (255) is fixed to the second spur gear (250), it moves together with the second spur gear (250). The second moving block (255) is located on the lower side of the envelope supply part (150) and is installed on the other side of the inner insertion part (112).

[0140] The first moving block (245) and the second moving block (255) are installed facing each other with the inner insertion part (112) in between. The first spur gear (240) is engaged with the upper side of the rotating gear (230), and the second spur gear (250) is engaged with the lower side of the rotating gear (230). Therefore, the first spur gear (240) and the second spur gear (250) move in opposite directions due to the rotation of the rotating gear (230). Additionally, the first spur gear (240) and the second spur gear (250) are installed parallel to each other, and the direction of movement of the first spur gear (240) and the second spur gear (250) is opposite.

[0141] For example, if the first moving block (245) is positioned to the right of the rotating gear (230) and the second moving block is positioned to the left of the rotating gear (230), the first moving block and the first spur gear (240) move to the left due to the counterclockwise rotation of the rotating gear (230). Then, the second spur gear (250) and the second moving block (255) move to the right. Accordingly, at the center of the inner insertion part (112) where the rotating gear (230) is located, the first moving block (245) and the second moving block (255) face each other with the fabric member (170) or envelope (500) in between.

[0142] Accordingly, the sealing and cutting operations of the envelope (500) and the fabric member (170) can be performed by the heat generated from the heater unit (260) installed in the first moving block (245) and the second moving block (255).

[0143] The first moving block (245) and the second moving block (255) may be made of heat-resistant silicone rubber. Alternatively, various modifications are possible, such as being made of blocks made of insulating material.

[0144] [Heater]

[0145] FIG. 10 is a perspective view illustrating a sealed drive unit (200) according to one embodiment of the present invention.

[0146] As illustrated in FIG. 10, the heater unit (260) is installed on the operating gear unit (220), and various types of heating devices may be used within the technical concept of simultaneously cutting and joining the envelope (500) by heating with the supply of power. The heater unit (260) may be installed on at least one side of the first moving block (245) and the second moving block (255). The heater unit (260) according to one embodiment of the present invention includes a first heating unit (270) installed on the first moving block (245) and a second heating unit (275) installed on the second moving block (255).

[0147] The first heating unit (270) is installed on the side of the first movable block (245) and generates heat by supplying power. The first heating unit (270) according to one embodiment of the present invention includes a heating wire member (271), a first support member (272), and a first cover member (273).

[0148] A first support member (272) is installed on the side of the first movable block (245), and a heating element (271) is installed on the outer side of the first support member (272). A first cover member (273) is installed on the outer side of the heating element (271). The heating element (271) is installed between the first support member (272) and the first cover member (273).

[0149] The first support member (272) is made of an insulating material to block the heat of the heating wire from being transferred to the first moving block (245). The first support member (272) according to one embodiment of the present invention is used as an insulating tape and is fixed to the side of the first isoconvex.

[0150] The first cover member (273) is made of Teflon fiber, but is not limited thereto, and other types of fibers with heat resistance may also be used as the first cover member (273). Teflon is a fiber made of polytetrafluoroethylene (PTFE) obtained by the addition polymerization of tetrafluoroethylene, and has excellent chemical resistance, heat resistance, and hydrophobicity.

[0151] The first cover member (273) may have a Teflon tape with a low friction coefficient installed to prevent it from melting due to the heat of the heating member (271) and adhering to the heating member (271).

[0152] The first heating unit (270) forms a heater module composed of a heating element (271), a first support member (272), and a first cover member (273) and is fixed to the side of the first movable block (245). The second heating unit (275) is installed on the side of the second movable block (255) facing the first heating unit (270) and generates heat by power supply. Since the detailed structure of the second heating unit (275) is identical to that of the first heating unit (270), a detailed description thereof is omitted.

[0153] [Sealing section]

[0154] As illustrated in FIGS. 4 and FIGS. 7 to 9, when the envelope (500) is pressed against the inside of the case part (10) by the operation of the blower fan (290), sealing parts (280) are installed on both sides of the sealing drive part (200) to minimize the volume of the internal space being sucked in. The sealing parts (280) may be installed in multiple numbers, and silicone, which has excellent sealing function but poor deformability, may be installed in the parts where no interference occurs during the movement of the operating gear part (220). Additionally, a brush with excellent shape deformation may be installed in the parts where interference occurs during the movement of the operating gear part (220).

[0155] In the present invention, sealing sections (280) are installed on both sides in the width direction (W) of a first moving block (245) in which a first heating section (270) is installed and a second moving block (255) in which a second heating section (275) is installed. The envelope supply section (150), the sealing drive section (200), and the sealing section (280) are installed in the door section (100) and rotate together with the door section (100). Additionally, a square frame-shaped sealing structure is formed by the sealing section (280), the first heating section (270), and the second heating section (275).

[0156] Therefore, when the blower fan (290) is operated to install a new bag (500) after discarding the bag (500) filled with food waste (600), the space filled with air to be sucked in by the blower fan (290) is reduced, so the bag (500) can be quickly unfolded.

[0157] The sealing portion (280) blocks the side space of the door portion (100) where the heater portion (260) is not installed, thereby minimizing the intake of air inside the door portion (100) by the blower fan (290). The sealing portion (280) according to one embodiment of the present invention includes a first sealing portion (282) and a second sealing portion (284).

[0158] The first sealing portion (282) is located on one side in the width direction (W) of the first moving block (245) and the second moving block (255) and extends along the movement path of the first moving block (245) and the second moving block (255). The first sealing portion (282) may use silicone. Alternatively, the first sealing portion (282) may be made of an elastic material and is fixed to the inside of the first door portion (110).

[0159] The second sealing part (284) is located on the other side of the width direction (W) of the first moving block (245) and the second moving block (255), and extends along the movement path of the first moving block (245) and the second moving block (255). Since interference occurs with the second sealing part (284) when the first moving block (245) and the second moving block (255) move, the second sealing part (284) can use a brush that facilitates bending motion.

[0160] Therefore, interference caused by the second sealing part (284) can be minimized when the first moving block (245) and the second moving block (255) move. In addition, the installation of the second sealing part (284) can reduce the phenomenon in which air in the inner space of the door part (100) moves to the blower fan (290) through the inner side of the case part (10).

[0161] [Blower Fan]

[0162] A blower fan (290) is installed in the case section (10), and various types of blower devices can be used within the technical concept of discharging air from the inside of the case section (10) to the outside of the case section (10). The blower fan (290) is installed between the outer case (20) and the inner case (30), and is installed at a position facing the blower hole (33) of the inner case (30).

[0163] The blower fan (290) expels air from the inside of the case section (10) to the outside of the case section (10), thereby inducing the unfolding of the envelope (500) into the inside of the case section (10). Since the blower fan (290) operates to automatically unfold the envelope (500) into the inside of the case section (10), the time required for reinstalling the envelope (500) can be shortened.

[0164] A blower fan (290) that functions to press the envelope (500) against the inside of the case part (10) is installed on the lower side of the case part (10). The blower fan (290) is installed on the lower side of the case part (10) or on the lower surface. Therefore, compared to the case where the blower fan (290) is installed on the upper side of the case part (10), the unfolding of the envelope (500) is made easier.

[0165] When a blower fan (290) is installed on the upper side of the case part (10), if a plastic bag (500) is moved by the operation of the blower fan (290) and blocks the opening of the blower fan (290), a problem occurs in which the bag (500) cannot be properly unfolded.

[0166] Therefore, when the blower fan (290) is installed on the lower side or lower surface of the case part (10), the opening of the blower fan (290) is blocked when the envelope (500) is fully unfolded, so the unfolding of the envelope (500) can be easily achieved.

[0167] In addition, when the blower fan (290) according to the present invention is installed on the lower surface of the case part (10), foreign matter may enter the interior of the blower fan (290), so the blower fan (290) is installed on the lower side of the case part (10).

[0168] [Damper section]

[0169] The damper unit (300) is connected to the blower fan (290), and allows the movement of air from the blower fan (290) toward the outside of the outer case (20), and blocks the movement of air from the outside of the outer case (20) toward the blower fan (290).

[0170] When there is no movement of air from the inside to the outside of the case part (10), the damper part (300) blocks the movement of air, thereby preventing the odor of food waste (600) inside the case part (10) from being discharged to the outside of the case part (10), which can increase consumer satisfaction.

[0171] [Control Unit]

[0172] FIG. 20 is a block diagram of an individually sealed food waste treatment device (1) according to one embodiment of the present invention.

[0173] As illustrated in FIGS. 4 and FIGS. 20, the control unit (310) is installed in the case unit (10), and various modifications can be implemented within the technical concept of controlling the operation of the blower fan (290) and the sealed drive unit (200). In one embodiment of the present invention, the control unit (310) is installed between the inner case (30) and the outer case (20). In addition, the control unit (310) controls the operation of the sterilization unit (140) and can receive charging information of the battery (320).

[0174] In addition, the control unit (310) receives the measurement value from the measurement unit (800) and can control the operation of the sealing drive unit (200) and the height adjustment unit (700).

[0175] The operation of the control unit (310) controlling the operation of the sealing drive unit (200) is described. The control unit (310) controls the temperature of the heater unit (260) provided in the sealing drive unit (200) to distinguish between the sealing and cutting operations of the envelope (500).

[0176] The heater unit (260) operates in a storage mode that seals the bag (500) containing food waste (600) without cutting it, and a discharge mode that seals the bag (500) containing food waste (600) and cuts the part connected to an adjacent bag (500).

[0177] In the storage mode, after food waste (600) is placed inside the bag (500), the opening of the bag (500) is sealed to store a small amount of food waste (600). Additionally, in the storage mode, since the sealed bag (500) and the adjacent bag (500) are not cut, the disposal of the bag (500) containing food waste (600) can be easily performed.

[0178] The cutting mode is activated when the bags (500) are discarded after a set number of bags (500) have been filled inside the case part (10). In the cutting mode, the operation of sealing the upper side of the bag (500) containing food waste (600) and the lower side of the fabric member (170) connected to the bag (500) and the operation of cutting the upper side of the sealed bag (500) are performed simultaneously.

[0179] The control unit (310) controls the temperature of the heater unit (260) provided in the sealing drive unit (200) to distinguish between sealing and cutting operations of the envelope (500). When the control unit (310) operates the heater unit (260) in storage mode, it operates at a lower temperature than the temperature of the heater unit (260) when operated in cutting mode. Therefore, in storage mode, since the temperature of the heater unit (260) is lower than the temperature required to cut the envelope (500), only sealing operations are performed without cutting the envelope (500).

[0180] In addition, in the cutting mode, the central temperature of the heater part (260) is higher than the temperature for cutting the envelope (500), and the upper and lower temperatures of the heater part (260) are formed to be lower than the temperature for cutting the envelope (500). Accordingly, the boundary line between the envelope (500) and the fabric member (170) connected thereto is cut, the lower side of the fabric member (170) above the cut boundary line is sealed, and the upper side of the envelope (500) below the boundary line is also sealed.

[0181] Additionally, the control unit (310) receives the measurement values ​​from the measurement unit (800) and the door sensor unit (810), and after food waste (600) is introduced into the bag (500), it operates the sealing drive unit (200) to seal the bag (500).

[0182] The measuring unit (800) is installed inside the case unit (10) and measures the height of the envelope (500) loaded in the height adjustment unit (700) and transmits the measured value to the control unit (310). According to one embodiment of the present invention, the measuring unit (800) is installed in multiple numbers along the vertical direction inside the case unit (10) and can measure the loading height of the envelope (500) by irradiating a light beam.

[0183] The door sensor unit (810) measures whether the door unit (100) is open or closed and transmits the measured value to the control unit (310). The door sensor unit (810) according to one embodiment of the present invention measures whether the second door unit (130) is opened when food waste (600) is disposed of in a bag (500). The door sensor unit (810) according to one embodiment of the present invention is installed in a position facing the second door unit (130) and can measure whether the second door unit (130) is open or closed by irradiation of a light beam or by a contact method.

[0184] The control unit (310) lowers the height of the height adjustment unit (700) as the height of the sealed envelope (500) loaded on the upper side of the moving support unit (710) increases, based on the value measured by the measuring unit (800). Since the control unit (310) controls the operation of the adjustment motor (742) of the height adjustment unit (700), the height of the moving control unit (310) is gradually lowered as the number of sealed envelopes (500) increases.

[0185] The operation of the height adjustment unit (700) is automatically controlled by the control unit (310) that receives the measurement value of the measuring unit (800) that measures the height of the envelope (500), so the convenience of use can be further improved.

[0186] [battery]

[0187] The battery (320) is located between the outer case (20) and the inner case (30), and various modifications can be implemented within the technical concept of supplying power to the blower fan (290) and the sealed drive unit (200). In addition, the battery (320) also supplies power to the sterilization unit (140). The battery (320) is charged through a charging terminal provided in the refrigerator (400) while the individual sealed food waste disposal device (1) is mounted in the refrigerator (400).

[0188] Since a battery (320) is installed in the individual sealed food waste disposal device (1), the individual sealed food waste disposal device (1) can be used independently even when separated from the refrigerator (400), thereby further improving the convenience of use of the device.

[0189] [Height adjustment section]

[0190] The height adjustment unit (700) is installed inside the case unit (10) to support the lower part of the bag (500), and various modifications can be implemented within the technical concept that allows for height adjustment in the up and down direction by the control of the control unit (310). As the number of sealed bags (500) increases, the height of the movable support unit (710) supporting the lower part of the bag (500) is gradually lowered, so that the loading of sealed bags (500) and the dropping of food waste (600) can be carried out stably.

[0191] A height adjustment unit (700) according to one embodiment of the present invention includes a movable support unit (710) and a height variable unit (720).

According to one embodiment of the present invention, the movable panel (712) is a rectangular panel and is installed horizontally on the inner side of the inner case (30).

[0196] The ventilation hole portion (714) penetrates the movable panel (712) in the vertical direction and forms a passage through which air moves. The ventilation hole portion (714) according to one embodiment of the present invention includes a plurality of ventilation holes (716) and is located on both sides in the width direction (W) of the movable panel (712).

[0197] A ventilation hole portion (714) according to one embodiment of the present invention is installed along both edges of a movable panel (712) and is installed parallel to each other.

[0198] [Variable height section]

[0199] The height variable part (720) is connected to the movable support part (710), and various modifications can be implemented within the technical concept of adjusting the height of the movable support part (710) by varying its length through an action of unfolding or folding in the up and down direction. The height variable part (720) moves in the up and down direction by the rotation of the adjustment motor (742). The height variable part (720) according to one embodiment of the present invention includes at least one of a base part (730), a driving part (740), a moving block (750), a moving guide part (760), a variable link part (770), a first connecting link (780), and a second connecting link (790).

[0200] The base portion (730) is located below the movable support portion (710) and is seated on the inside of the case portion (10). The base portion (730) is installed on the inner lower surface of the case portion (10) and forms a groove or hole portion through which the end of the variable link portion (770) moves. The base portion (730) according to one embodiment of the present invention includes at least one of a side base (732), a support bracket (736), and a lower plate (738).

[0201] The side base (732) is provided with a first guide hole (734) in the shape of an elongated hole that guides the first connecting link (780), which connects the movable block (750) and the variable link part (770), in a horizontal direction. The side base (732) according to one embodiment of the present invention is installed in a shape that is erected on both sides in the width direction (W) of the movable block (750), and the rotation of the movable block (750) is restricted by the side base (732), and only linear movement is allowed.

[0202] The support bracket (736) is fixed to the side base (732), and various modifications can be implemented within the technical concept of supporting the drive unit (740). In one embodiment of the present invention, the support bracket (736) is installed in an upright state by connecting the ends of the side base (732). Side bases (732) are installed on both sides of the support bracket (736).

[0203] The lower plate (738) supports the side base (732) and the support bracket (736) and is installed on the lower side of the side base (732) and the support bracket (736). The lower plate (738) is plate-shaped and supports the lower part of the movable block (750).

[0204] The drive unit (740) is fixed to the base unit (730), and various types of drive devices can be used within the technical concept of supplying rotational power. The drive unit (740) according to one embodiment of the present invention includes a control motor (742) and a screw bar (744).

[0205] The control motor (742) is fixed to the base part (730) and supplies rotational power by receiving power. Additionally, the control motor (742) is operated by a control signal from the control part (310). The control motor (742) is fixed to the support bracket (736), and a screw bar (744) is connected to the control motor (742).

[0206] The screw bar (744) is connected to the output of the control motor (742) and rotates by receiving power from the control motor (742). A spiral male screw is formed on the outer side of the screw bar (744). Since the screw bar (744) is fastened to a female screw provided in the movable block (750), the movable block (750) is moved by the rotational movement of the screw bar (744).

[0207] The moving block (750) is positioned between a pair of side bases (732) and is installed in a shape that intersects with the screw bar (744). The moving block (750) receives power from the driving unit (740) and can be implemented in various variations within the technical concept of moving along the base unit (730) in the longitudinal direction. According to one embodiment of the present invention, the moving block (750) is a block in the shape of a rectangular parallelepiped, and the screw bar (744) is installed in a shape that penetrates the moving block (750). In addition, a female screw is provided on the inner side of the moving block (750), and a male screw is provided on the outer side of the screw bar (744). Therefore, when the screw bar (744) is gear-connected to the moving block (750) and the screw bar (744) rotates, the moving block (750) is in contact with the side base (732) and rotation is restricted, so only linear movement along the direction in which the screw bar (744) is installed is allowed.

[0208] The variable link section (770) is installed in the vertical direction and can be moved by the operation of the control motor (742), allowing for various modifications within the technical concept in which its length is varied by folding or unfolding in the vertical direction. According to one embodiment of the present invention, the lower side of the variable link section (770) is connected to the movable block (750) and the base section (730), and the upper side is connected to the movable panel (712) or the movable guide section (760) connected to the movable panel (712). Furthermore, the lower side of the variable link section (770) is connected to the movable block (750) by the first connecting link (780), and the vertical length of the variable link section (770) is varied by the movement of the movable block (750).

[0209] The movement guide section (760) is connected to both sides in the width direction (W) of the movement panel (712) and is provided with a second guide hole (765) in the shape of an elongated hole that guides the second connecting link (790), which is connected to the upper side of the variable link section (770), in the horizontal direction. The movement guide section (760) extends to the lower side of the movement panel (712) and is provided with a second guide hole (765) on its inner side.

[0210] A second connecting link (790) is inserted into the second guide hole (765), the head of the second connecting link (790) is caught in the second guide hole (765), and the end of the second connecting link (790) is connected to the upper side of the variable link part (770).

[0211] The variable link section (770) is formed as a pair and is installed on each side base (732). The variable link section (770) has two links installed in a zigzag shape, and two ends are provided on the lower side of the variable link section (770). One end of the lower end of the variable link section (770) is fixed to the side base (732), and the other end is connected to the movable block (750) through the first connecting link (780).

[0212] Two ends are provided on the upper side of the variable link section (770). One end of the upper end of the variable link section (770) is fixed to the moving guide section (760), and the other end is connected to the second connecting link (790).

[0213] The first connecting link (780) is a pin shape that is inserted into the first guide hole (734) and installed in a horizontal direction, and the second connecting link (790) is a pin shape that is inserted into the second guide hole (765) and installed in a horizontal direction.

[0214] Since one side of the lower end of the variable link section (770) is fixed and the other side is moved horizontally together with the moving block (750), the variable link section (770) is unfolded or folded, and as a result, the vertical length of the variable link section (770) is varied.

[0215] [Operation of Individually Sealed Food Waste Disposal Devices]

[0216] Hereinafter, the operating state of an individual sealed food waste treatment device (1) according to one embodiment of the present invention will be described in detail with reference to the attached drawings.

[0217] FIG. 14 is a cross-sectional view illustrating the state in which an envelope (500) is unfolded inside a case part (10) by the operation of a blower fan (290) according to one embodiment of the present invention.

[0218] As illustrated in FIG. 14, with the height-variable section (720) unfolded, the movable support section (710) is raised to an upper set height. The bag (500) is unfolded on the upper side of the movable support section (710). A bag (500) for holding food waste (600) is installed inside the case section (10). The control section (310) can stop the operation of the blower fan (290) by receiving a measurement value from a sensor member that detects that the installation of the bag (500) is complete. Alternatively, the control section (310) can automatically stop the operation of the blower fan (290) after a set time.

[0219] FIG. 15 is a cross-sectional view illustrating the state in which food waste (600) supplied through the second door section (130) according to one embodiment of the present invention is loaded into a bag (500).

[0220] As illustrated in FIG. 15, the second door section (130) is opened and food waste (600) is disposed of inside the case section (10). The food waste (600) is placed inside a bag (500), and when the disposal of food waste (600) is completed, the second door section (130) is closed and the food waste (600) disposal device is stored in the freezer of the refrigerator (400). Since the food waste (600) inside the case section (10) is frozen by the cold air of the freezer, the decay of the food waste (600) is prevented, and the generation of odor from the food waste (600) can also be minimized.

[0221] FIG. 16 is a cross-sectional view illustrating the state in which the upper part of the envelope (500) is sealed by operating the sealing drive unit (200) according to one embodiment of the present invention.

[0222] As illustrated in FIG. 16, when the second door unit (130) is closed, the door sensor unit (810) detects the closing of the second door unit (130) and transmits the measurement value to the control unit (310). The control unit (310) operates the sealing drive unit (200) to seal the upper side of the bag (500) containing food waste (600). At this time, the temperature of the heater unit (260) is adjusted so as not to cut the fabric member (170) connected to the upper side of the bag (500) and the bag (500).

[0223] The first moving block (245) and the second moving block (255) of the sealing drive unit (200) are moved to the center of the case unit (10) and come into contact with both sides of the envelope (500). A first heating unit (270) is installed in the first moving block (245), and a second heating unit (275) is installed in the second moving block (255) to apply heat while pressing between the envelope (500) and the fabric member (170).

[0224] Therefore, the envelope (500) and the fabric member (170) are fused by heat, and the upper side of the envelope (500) and the lower side of the fabric member (170) are sealed.

[0225] After discarding food waste (600) once inside the bag (500), the top of the bag (500) can be sealed. Alternatively, after discarding a small amount of food waste (600) inside the bag (500), the top of the bag (500) can be sealed to block the spread of odors generated from the food waste (600).

[0226] FIG. 17 is a cross-sectional view illustrating a sealed envelope (500) lowered together with a movable support member (710) according to one embodiment of the present invention.

[0227] As illustrated in FIG. 17, when the operation of the sealed drive unit (200) is completed, the control unit (310) operates the adjustment motor (742) of the height adjustment unit (700). When the adjustment motor (742) is operated to rotate the screw bar (744), the moving block (750) engaged with the screw bar (744) moves away from the drive motor (210).

[0228] When the first connecting link (780) connected to the moving block (750) moves along the first guide hole (734), the variable link part (770) connected to the first connecting link (780) also moves away from the driving motor (210). Consequently, since the variable link part (770) is folded from an unfolded state, the vertical length of the variable link part (770) is reduced.

[0229] And a new bag (500) for holding food waste (600) is installed on the upper side of the sealed bag (500).

[0230] FIG. 18 is a cross-sectional view illustrating a state in which a space for storing food waste (600) is divided into multiple sections inside a case part (10) according to one embodiment of the present invention.

[0231] As shown in FIG. 18, the second door section (130) is opened and food waste (600) is disposed of inside the case section (10). The food waste (600) is placed inside the bag (500) located above the sealed bag (500), and when the disposal of food waste (600) is completed, the second door section (130) is closed.

[0232] FIG. 19 is a perspective view illustrating a state in which a plurality of sealed envelopes (500) are discharged from a case part (10) according to one embodiment of the present invention.

[0233] As illustrated in FIG. 19, with the second door unit (130) closed, the sealing drive unit (200) is operated to seal the upper side of the bag (500) containing food waste (600). At the same time, the boundary between the sealed bag (500) and the fabric member (170) located on the upper side of the bag (500) is also cut. At this time, the lower side of the fabric member (170) is sealed by heat fusion of the heater unit (260) to form the lower part of the bag (500) to be supplied.

[0234] The sealing and cutting operations by the heater section (260) are explained in more detail. The parts facing the heating wire in the first heating section (270) and the second heating section (275) have a high temperature, and the upper and lower sides of the heating wire have a lower temperature relative to the heating wire.

[0235] Accordingly, the boundary between the envelope (500) facing the heating wire and the fabric member (170) is cut by the high heat of the heating wire. And the first heating part (270) and the second heating part (275), which have a relatively lower temperature than the heating wire and are located above the heating wire, seal the lower side of the fabric member (170) by heat fusion.

[0236] In addition, the first heating unit (270) and the second heating unit (275), which have a relatively lower temperature than the heating element and are located below the heating element, press and seal both upper sides of the envelope (500). Since the heater unit (260) of the sealing drive unit (200), which is heated to a high temperature, operates to press the upper part of the envelope (500), the upper part of the envelope (500) is fused by the heat of the sealing drive unit (200) and is automatically sealed.

[0237] Then, the user opens the door (100) and performs the task of taking out and discarding the multiple sealed envelopes (500).

[0238] In an individual sealed food waste disposal device (1) according to one embodiment of the present invention, the operation of sealing the upper side of a bag (500) containing a small amount of food waste (600) is performed automatically, and the operation of collecting a plurality of sealed bags (500) and disposing of them at once is performed. Since the bag (500) containing food waste (600) is sealed in small quantities and stored inside the case part (10) before being disposed of, the generation of bad odors caused by food waste (600) can be prevented even before the food waste (600) is frozen.

[0239] Although the present invention has been described above with reference to the illustrated drawings, the present invention is not limited by the embodiments and drawings disclosed in this specification, and it is obvious that various modifications can be made by a person skilled in the art within the scope of the technical concept of the present invention. Furthermore, even if the effects of the configuration of the present invention were not explicitly described while explaining the embodiments of the present invention above, it is natural to acknowledge that the effects predictable by said configuration should also be recognized.
