[0033] Hereinafter, a range hood (1) according to one embodiment of the present invention will be described with reference to the attached drawings.

[0034] The range hood (1) of the present example is configured to suck in air from a space such as a kitchen where a kitchen exhaust structure (20) is installed, by means of operation of a driving unit (211), and to discharge it to the outside through the kitchen exhaust structure (20).

[0035] The range hood (1) of this example may be equipped with a mounting structure (10) and an exhaust structure (20) mounted on the mounting structure (10), as shown in FIGS. 1 to 3.

[0036] The mounting structure (10) may have an empty space inside, as shown in FIGS. 3 to 5, and may have a polygonal or circular planar shape such as a rectangle.

[0037] The mounting structure (10) comprises a hood case (11) having an open bottom and an empty space inside, a filter section (12) having at least one filter section (e.g., a first filter section (121) and a second filter section (122)) positioned in the empty space within the hood case (11) and spaced apart from each other along the height direction of the mounting structure (10), a blocking plate (13) positioned in the empty space within the hood case (11) and positioned above the second filter section (122), a first support section (141) and a second support section (142) positioned on each side of the hood case (11) and supporting the second filter section (122), a first guide section (151) and a second guide section (152) positioned between the hood case (11) and the blocking plate (13) to move the position of the second filter section (122) in the corresponding direction (e.g., forward direction and rear direction), and a blocking plate (13) connected to the A handle part (16) may be provided.

[0038] The hood case (11) contains a blocking plate (13) located at the bottom, a second filter part (122), and a first filter part (121), and may have a flat shape identical to the flat shape of these.

[0039] Accordingly, the hood case (11) has a rectangular flat shape and may have an internal space for housing a blocking plate (13), a second filter part (122), and a first filter part (121), etc.

[0040] The front and bottom parts of this hood case (11) may be open.

[0041] Accordingly, the hood case (11) of the present example may have an upper surface (111), a left side (112), a right side (1113), a rear surface (114), and a lower surface (115) that is connected without interruption to the left side (112), the right side (113), and the rear surface (114).

[0042] Additionally, the hood case (11) may have first to third inner surfaces (15a-15c) that are continuously connected to the inner edge of the lower surface (115). At this time, the first inner surface (15a) and the second inner surface (15b) may face the left side (112) and the right side (113), respectively, and may be located adjacent to the left side (112) and the right side (113), and the third inner surface (15c) may face the rear surface (115) and may be located adjacent to the rear surface (115).

[0043] A mounting hole (H15) may be located on each of the first inner surface (15a) and the second inner surface (15b), so that the first filter portion (121) can be mounted to the hood case (11) through the mounting hole (H15).

[0044] For example, mounting protrusions (P121) that can be inserted into mounting holes (H15) may be positioned on the left and right sides of the first filter portion (121), respectively, and as each mounting protrusion (P121) is inserted into the corresponding mounting hole (H15), the first filter portion (121) can be mounted on the hood case (11).

[0045] Accordingly, the height of the internal space of the hood case (11), which is enclosed by the upper surface (111), left side (112), right side (113), rear (114) and lower surface (115), can be determined according to the height of the left side (112), right side (113) and rear (114) (i.e., the size in the vertical direction).

[0046] An air penetration section (16) having a plurality of slit-shaped penetration holes (H16) that completely penetrate the upper surface (111) may be located in the approximately center portion of the upper surface (111) of the hood case (11). Accordingly, the upper surface (111) of the hood case (11) may be provided with an air penetration section (16) having a plurality of air penetration holes (H16).

[0047] Multiple through holes (H16) are spaced apart from each other and can have various sizes and shapes.

[0048] At this time, if the ends of the air penetration holes (H16) positioned at the outermost edge are connected, they can have a roughly circular shape, and as a result, the air penetration part (16) can have a circular planar shape.

[0049] These air penetrations (16) may be parts that allow air introduced into the mounting structure (10) to pass through a plurality of penetrations (H16) and send it toward the exhaust structure (20).

[0050] As previously described, the lower surface (115) can be positioned to be connected along the edge of the hood case (11), and the first support member (141) and the second support member (142) are positioned on this lower surface (115) so that the positions of the first support member (141) and the second support member (142) can be stably maintained.

[0051] As previously described, the filter section (12) may have a first filter section (121) and a second filter section (122) positioned sequentially spaced apart from each other along the height direction (e.g., up and down direction) of the mounting structure (10) from the bottom.

[0052] The first filter portion (121) and the second filter portion (122) may have the same size and shape as each other, and, for example, may have a plate shape having a rectangular planar shape.

[0053] These first filter portion (121) and second filter portion (122) are each equipped with a grease filter for mainly removing grease components contained in the inhaled air.

[0054] Therefore, when air sucked into the range hood (1) passes through the first filter section (121) and the second filter section (122), purified air with grease components removed can be sucked into the exhaust structure (20).

[0055] In this example, the first filter portion (121) can be coupled and mounted to the hood case (11) as previously described, and the second filter portion (122) can be coupled directly or indirectly to the blocking plate (13) and assembled integrally to the blocking plate (13).

[0056] The blocking plate (13) can be positioned on the second filter portion (122) and can be installed to move forward and backward along the first support portion (141) and the second support portion (142).

[0057] These blocking plates (13) may have a roughly rectangular flat shape, and the bottom surface may be open, and the top surface, left side, right side, front and rear surfaces may be connected to the top surface without interruption.

[0058] Accordingly, the blocking plate (13) may have an internal space enclosed by an upper surface, a left side, a right side, a front, and a rear, and a second filter part (122) may be embedded and positioned within this internal space. At this time, the upper surface of the second filter part (122) may be positioned in contact with the inner surface of the upper surface of the blocking plate (13), so that the second filter part (122) may be positioned integrally and detachably on the blocking plate (13).

[0059] For connection with the second filter portion (122), at least one mounting hole is provided on each side of the blocking plate (13) or on each side of a separate connecting portion (not shown) located on the blocking plate, and each side of the second filter portion (122) may also be provided with at least one mounting projection (P122) corresponding to the mounting hole.

[0060] Accordingly, when the second filter portion (122) is directly or indirectly connected to the blocking plate (13) through a connecting part and assembled integrally with the blocking plate (13), the second filter portion (122) can also move in the forward and backward directions according to the movement of the blocking plate (13).

[0061] The left and right sides of the blocking plate (13) can be positioned in a movable state, for example, in a free state not connected to either the first support member (141) and the second support member (142), respectively. Thus, the blocking plate (13) can move in the forward and backward directions along the first support member (141) and the second support member (142).

[0062] In this way, a blocking plate (13) is positioned on the upper part of the second filter portion (122), and as the blocking plate (13) is combined with the second filter portion (122), the upper surface of the second filter portion (122) may be covered by the blocking plate (13).

[0063] At this time, the portion of the blocking plate (13) covering the filter mounted on the second filter portion (122) may be in the shape of a plate that is completely blocked without any openings and may be made of a material (e.g., aluminum) that does not allow air to pass through.

[0064] Therefore, since the air passing through the filter of the second filter section (122) may not pass through the blocking plate (13), the air passing through the second filter section (122) may move toward the exhaust structure (20) along the inner surface of the upper surface of the blocking plate (13) instead of moving in an upward direction, and may be sucked toward the exhaust structure (20) by passing through the air penetration section (16) located in the hood case (110).

[0065] The first support member (141) and the second support member (142) can be positioned to be seated on both sides of the lower surface of the hood case (11), for example, the left and right sides, respectively, and can have the same shape as each other.

[0066] For example, the first support member (141) and the second support member (142) may each have a cross-sectional shape approximately in the shape of an 'L', as shown in FIGS. 4 and FIGS. 5.

[0067] Accordingly, the first support member (141) and the second support member (142) may each have a structure having a step difference and may be positioned in a left-right inverted form in the hood case (11) as shown in FIGS. 4 and 5.

[0068] Accordingly, the lower left and right sides of the lower surface of the second filter part (122) can be positioned on the seating surface (S14) of the first support part (141) and the second support part (142), respectively.

[0069] As a result, the second filter portion (122) coupled to the blocking plate (13) can be supported by the first support portion (141) and the second support portion (142), and can move in the forward and backward direction along the first support portion (141) and the second support portion (142), which are fixed in position.

[0070] The first guide section (151) and the second guide section (152) move the blocking plate (13), which is combined with the second filter section (122), in the forward and backward directions so that the blocking plate (13) can slide.

[0071] These first guide portion (151) and second guide portion (152) may have the same structure and may be fixedly positioned on the outer surface of the upper surface of the sealing plate (13) and the inner surface of the upper surface of the hood case (11), respectively.

[0072] In this example, the first guide part (151) and the second guide part (152) may each have a movable rail shape having a first part (15a) fixed to the outer surface of the upper surface of the sealing plate (13) and a second part (15b) fixed to the inner surface of the upper surface of the hood case (11).

[0073] Accordingly, the first part (15a), which is located inside the second part (15b) and overlaps with the second part (15b), can move in the forward and backward directions along the extension direction of the second part (15b), and through the operation of the first guide part (151) and the second guide part (152), the blocking plate (13) connected to the first part (15a) can also move in the forward and backward directions.

[0074] Accordingly, the blocking plate (13) combined with the second filter portion (122) may be located inside the hood case (11) or may move forward away from the hood case (11) and protrude outside the hood case (11).

[0075] When the blocking plate (13) located between the first filter portion (121) and the air penetration portion (16) of the hood case (11) moves forward and protrudes outside the hood case (11), the air penetration portion (16) of the hood case (11) can be located right next to the first filter portion (121).

[0076] Accordingly, the purified air that has passed through the first filter section (121) can pass through the air penetration port (H16) of the air penetration section (16) located directly above and move toward the exhaust structure (20).

[0077] The handle portion (16) can be connected to the front of the blocking plate (13) using a fastening means such as a screw, and can be integrally connected to the blocking plate (13).

[0078] Additionally, the handle portion (16) can cover the front of the open hood case (11) to improve the aesthetics of the range hood (1).

[0079] Accordingly, when the user grasps the handle portion (16) and pulls the handle portion (16) forward, the blocking plate (13) connected to the handle portion (16) can move forward, so that the blocking plate (13) can protrude outward from inside the hood case (11).

[0080] Due to the protruding movement of the blocking plate (13), as previously explained, the second filter part (122) located at the bottom of the blocking plate (13) and assembled to the blocking plate (13) can also be exposed to the outside.

[0081] Accordingly, when the user pulls the handle portion (16) toward the first direction (e.g., forward), the blocking plate (13) connected to the handle portion (16) and the second filter portion (122) located below the blocking plate (13) also move toward the forward, so that the second filter portion (122) can protrude outward from inside the hood case (11) and spread outward.

[0082] Conversely, when the user pushes the handle portion (16) in the second direction (e.g., rearward) opposite to the first direction, the blocking plate (13) combined with the second filter portion (122) moves toward the rearward direction, and the blocking plate (13) can be inserted into the hood case (11) at its initial position, and as a result, the second filter portion (122) can also be positioned inside the hood case (11) at its initial position.

[0083] At this time, unlike the second filter part (122), the first filter part (121) can always be located inside the hood case (11) regardless of the operation of the handle part (16).

[0084] The range hood (1) of the present example may further be equipped with a drive switch that changes its operating state according to the position change of the blocking plate (13).

[0085] Accordingly, depending on the state of the drive switch, if the blocking plate (13) moves from the initial position to the first direction by a set amount, the state of the drive switch may change, and a control unit not shown may detect such change in the state of the drive switch and drive the exhaust structure (20).

[0086] Accordingly, depending on the operation of the exhaust structure (20), the air located at the bottom of the mounting structure (10) can be sucked in and flowed toward the exhaust structure (20).

[0087] Next, the structure of the exhaust structure (20) will be explained with reference to FIGS. 3, FIGS. 6 and FIGS. 7.

[0088] The exhaust structure (20) can be mounted on the upper surface (111) of the hood case (11), more specifically on the part of the upper surface (111) where the air penetration (16) is located. Thus, the air penetration (16) can be located inside the exhaust structure (20), so that air passing through the air penetration (16) can be sucked into the exhaust structure (20) and then discharged to the outside.

[0089] In this way, the exhaust structure (20) of the present example can be mounted on the upper surface (111) of the mounting structure (10) and positioned to protrude upward from the upper surface (111) of the mounting structure (10).

[0090] As shown in FIGS. 6 and 7, this exhaust structure (20) may be provided with a centrifugal separator (21) and a housing (22) positioned above the centrifugal separator (21) to house the centrifugal separator (21) inside.

[0091] The centrifugal separation unit (21) can be located inside the housing (22) and can rotate in the corresponding direction.

[0092] Accordingly, the centrifugal separation unit (21) rotates at a predetermined speed and in a predetermined direction to rotate the air introduced from the air penetration unit (16) of the mounting structure (10) in a predetermined direction, so that foreign substances such as at least one of grease components and moisture contained in the inhaled air can be discharged to the outside by centrifugal force, and the inhaled air can move toward the housing (22).

[0093] Due to the rotational movement of the centrifugal unit (21), foreign substances contained in the inhaled air can be ejected toward the housing (22) located adjacent to the centrifugal unit (21). At this time, the order of discharge of foreign substances by the outward ejection movement in the inhaled air can be discharged starting from the heavier components.

[0094] As such, the centrifugal separation unit (21) of the present example can utilize the centrifugal force generated by its own rotational movement, and thus may be equipped with a driving unit (211) having a motor that rotates according to a control signal applied from the outside and a driving circuit that drives the motor, and a separation unit body (212) to which the driving unit (211) is located and coupled. The driving unit (211) may be operated according to the control of the control unit so that its rotational state can be controlled.

[0095] As previously described, the driving unit (211) may further be provided with a rotating shaft (211a) that is coupled with the main body (212) of the separation unit.

[0096] The main body (212) of the separation part may have a circular planar shape with an open bottom.

[0097] As illustrated in FIGS. 6 and 7, the separating body (212) may have an upper surface (T21), a lower surface (B21) facing the upper surface (T21) on the opposite side of the upper surface (T21), and a plurality of wings (W21) located between the upper surface (T21) and the lower surface (B21).

[0098] The upper surface (T21) of the main body (212) of the separation part may have a flat portion (P211) having a circular planar shape as shown in FIG. 6, and a recessed portion (P212) that is completely surrounded by the flat portion (P211) and located approximately in the center. As a result, the flat portion (P211) may be located on the outer side of the upper surface (T21), and the recessed portion (P212) may be located on the inner side.

[0099] At this time, the recess (P212) can function as an insertion part for the driving part (211) into which the driving part (211) is inserted and located, and a coupling hole (H212) can be located in the center of the recess (P212) for stable coupling with the recess (P212).

[0100] Accordingly, the rotation axis (211a) of the driving unit (211) is inserted into the coupling hole (H212) of the recess (P212), so that the driving unit (211) can be fixedly coupled to the recess (P212). As a result, when the driving unit (211) rotates, the separating unit body (212) can also rotate together, so that the separating unit body (212) can rotate together in the same direction as the rotation direction of the driving unit (211).

[0101] As illustrated in FIGS. 1 and 3, a portion of the driving unit (211) located within the recess (P212) may pass through the recess (P212) and the housing (22) located above it in sequence and protrude outward, and the protruding portion of the driving unit (211) may be coupled to the housing (22).

[0102] The lower surface (B21) of the separating body (212) may have a circular band shape with a hollow space in the center and may have a diameter larger than the diameter of the upper surface (T21).

[0103] Since the upper surface (T21) and the lower surface (B21) of the separating body (212) are spaced apart from each other in the vertical direction (i.e., height direction) at a predetermined distance, a plurality of wings (W21) can be positioned spaced apart along the edges of the upper surface (T21) and the lower surface (B21) in this vertically spaced space.

[0104] Multiple wings (W21) may have the same size and shape as each other and, as previously described, may be positioned spaced apart at a predetermined interval between the upper surface (T21) and the lower surface (B21). Accordingly, multiple wings (W21) may be arranged adjacently along the extension direction (i.e., circular direction) of the edge of the upper surface (T21) of the separating body (212).

[0105] Accordingly, one side of each wing (W21) can be positioned by being connected to the upper surface (T21), and the other side can be positioned by being connected to the lower surface (B21).

[0106] As previously described, since the diameter of the lower surface (B21) is larger than the diameter of the upper surface (T21), the position of one end of the wing (W21) may coincide with the outer edge of the upper surface (T21), and the position of the other end of the wing (W21) may coincide with the inner edge of the lower surface (B21).

[0107] As a result, the upper surface (T21), lower surface (B21), and multiple wings (W21) of the separating body (212) can be integrally combined.

[0108] Accordingly, a plurality of wings (W21) are positioned in the empty space in the center of the lower surface (B21), so that the lower surface (B21) can be positioned to surround the plurality of wings (W21) from the outside.

[0109] At this time, the lower surface (B21) of the main body (212) of the separation part also surrounds the air exhaust part (222) located in the hood case (11) of the mounting structure (10), so that the air exhaust part (222) can be located within the area surrounded by the lower surface (B21).

[0110] Due to these upper surface (T21), lower surface (B21) and multiple wings (W21), the centrifugal separation unit (21) can form an internal space surrounded by the upper surface (T21), lower surface (B21) and multiple wings (W21), and air from the mounting structure (10) can be introduced into this internal space.

[0111] Each wing may be a curved plate having a defined curvature, as shown in FIG. 6, and may be positioned to extend along the flat portion (P211) of the separating body (212). At this time, each wing may be positioned obliquely on the flat portion (P211) of the upper surface (T21) in a direction that crosses the width (D1) of the flat portion (P211), for example, in a diagonal direction.

[0112] At this time, each wing (W21) may be a curved plate bent in the same direction (e.g., left direction).

[0113] In this way, since a plurality of wings (W21) are positioned between the upper surface (T21) and the lower surface (B21) of the separation unit body (212), the plurality of wings (W21) can form the side of the centrifugal separation unit (21), more specifically, the separation unit body (212). That is, the side of the centrifugal separation unit (21) can be provided with a plurality of wings arranged side by side at spaced intervals.

[0114] Since there is an empty space between the two adjacent wings (W21), a part of the side of the centrifugal separation unit (21) may be exposed, and the empty space between the two adjacent wings (W21) that is open may become an air passage (OP22) that extends in the vertical direction.

[0115] Accordingly, by the rotational movement of the drive unit (211), the upper surface (S22) of the separation unit body (212) connected integrally with the drive unit (211) is rotated, and by the rotation of the upper surface (S22), a plurality of wings (W21) and a lower surface (B21) can also be rotated together with the drive unit (211).

[0116] Due to the rotational movement of the centrifugal separation unit (21), air located in the internal space of the centrifugal separation unit (21) can be discharged to the outside of the centrifugal separation unit (21) through the air passage (OP22), which is the space between adjacent wings (W21).

[0117] At this time, since multiple wings (W21) are positioned diagonally with respect to the virtual side of the separation unit body (212), the air discharged to the outside of the centrifugal separation unit (21) does not scatter outward and can rotate in correspondence with the rotation of the centrifugal separation unit (21) (40) along the curved direction of the wings. At this time, the direction of rotation of the air may be the same as the direction of rotation of the centrifugal separation unit (21).

[0118] Centrifugal force is generated by the rotation of the centrifugal separation unit (21), and foreign substances contained in the intake air, such as moisture or oil heavier than air, can be ejected outward by this centrifugal force and discharged from the intake air, thereby allowing for additional removal of foreign substances from the intake air.

[0119] At this time, since the housing (22) covers the centrifugal separation unit (21) from the outside, foreign substances discharged to the outside can be flung toward the inner surface of the housing (22).

[0120] As a result, the separated foreign matter can be positioned on the inner surface of the housing (22) and the air discharged to the outside of the centrifugal separation unit (21) can rotate along the inner surface of the housing (22).

[0121] After separating the housing (22) from the exhaust structure (20), the user or manager can easily remove foreign matter attached to the housing (22) through a separate cleaning process.

[0123] The housing (22) can be positioned to be coupled to the upper surface of the mounting structure (10), and as previously described, it can be positioned on the upper surface (T21) of the centrifugal separation part (21) so that the centrifugal separation part (21) is located inside.

[0124] This housing (22) may be provided with a centrifugal separation unit position (221) having an open bottom and an empty space (H221) inside, an air discharge unit (222) connected to the outside and having an empty space (H222) connected to the empty space (H221) of the centrifugal separation unit position (221), and a component position (223) having a space (H223) separated from the empty space (H221) of the centrifugal separation unit position (221) and the empty space (H222) of the air discharge unit (222).

[0125] The centrifugal separation part location portion (221) is the part where the centrifugal separation part (21) is located, and may have an upper surface (T221) and a side surface (S221).

[0126] The upper surface (T221) may be provided with a drive unit (211) penetration hole (H221) that allows a part of the drive unit (211), which protrudes upward from the centrifugal separation unit (21) as shown in FIGS. 1 and 3, to pass through and protrude to the outside of the upper surface (T221).

[0127] Accordingly, the driving unit (211) can protrude outward by passing through the driving unit (211) through hole (H221) and can be coupled to the upper surface (T221) of the centrifugal separation unit position (221) adjacent to the driving unit (211) through hole (H221) using fastening means such as a screw.

[0128] The air discharge section (222) can protrude upward from the upper surface of the centrifugal separation section (221).

[0129] This air outlet (222) may be provided with an air outlet (H222) having one side connected to the empty space (H221) of the centrifugal separation unit location (221) and the other side connected to the outside. Accordingly, air discharged from the centrifugal separation unit (21) toward the housing (22) can be discharged to the outside through the air outlet (H222).

[0130] At this time, the air discharge unit (222) may be equipped with an air flow control panel (222a) mounted on the top of the air discharge port (H222) and having an opening / closing state that changes according to the air flow.

[0131] This air flow control panel (222a) can control the state of the air flow to change according to the direction in which the air is applied, so that the air can move in only one direction.

[0132] In this example, when the air inside the housing (22) moves in a direction (e.g., upward) to be discharged to the outside through the air outlet (H222), the air flow control panel (222a) can be folded upward around the central axis according to the input of this air.

[0133] As a result, the air outlet (H222) that was blocked by the air flow control panel (222a) can be opened. Therefore, the air inside the housing (22) can be discharged to the outside through the open air outlet (H222).

[0134] On the other hand, if air is introduced from the outside towards the air outlet (H222) in a direction (e.g., downward direction) or if the airflow moving upward is reduced to a set state, the airflow control panel (H222) can be folded downward around the central axis to return to the initial state.

[0135] As a result, the open air outlet (H222) is closed by the air flow control panel (222a), so that air can be prevented from entering the housing (22) from the outside through the air outlet.

[0136] A pipe not shown may be connected to this air discharge section (222), so that air passing through the air discharge section (222) can be discharged to the outside through the connected pipe.

[0137] The component location portion (223) is a portion where wiring, etc., for applying power and control signals, etc., necessary for the operation of the driving portion (211) to the driving portion (211) is located, and may be provided with an empty space (H223) surrounded by an upper surface (T222), a side surface, and a lower surface (B223).

[0138] Unlike the air discharge section (222), this part location section (223) can be located on the same plane as the centrifugal separation section location section (221).

[0139] Therefore, the height of the upper surface (T223) of the part position portion (223) and the height of the upper surface (T221) of the centrifugal separation portion position portion (221) may be the same.

[0140] At this time, the upper surface (T223) of the component positioning part (223) can be connected to the side of the component positioning part (223) through screws, etc., so that it can be positioned so as to be detachable from the side as needed by the user. Accordingly, the user can detach the upper surface (T223) of the component positioning part (223) and perform operations such as replacing a component located in the internal space of the component positioning part (223).

[0141] Accordingly, each side of the centrifugal separation section (221), the air discharge section (222), and the component section (223) is connected to one another, so that these sides can ultimately form the sides of the housing (22), and the upper surface (T221) of the centrifugal separation section (221) can form at least a part of the upper surface of the housing (22), and the lower surface (B223) of the component section (223) can form at least a part of the lower surface of the housing (22).

[0142] According to the range hood (1) of this example, the exhaust structure (20) is mounted on the mounting structure (10), so that the exhaust structure (20) can be substantially located on the outside of the mounting structure (10).

[0143] Therefore, since the exhaust structure (20) is not located inside the mounting structure (10), the exhaust structure (20) is not located in the internal space of the mounting structure (10).

[0144] As a result, the mounting structure (10) is greatly reduced, and the overall volume of the range hood (1) can also be greatly reduced.

[0145] For use of the range hood (1) having this structure, first, the user can move the blocking plate (13), to which the second filter part (122) is attached, forward using the handle part (16).

[0146] As a result, as shown in FIG. 8, the second filter portion (122) can protrude forward from the first filter portion (121), and as shown in FIG. 9, the air passage (16) of the hood case (11) that was blocked by the blocking plate (13) can be located directly above the first filter portion (121).

[0147] As previously described, since the first filter section (121) and the second filter section (122) are spaced apart, an empty space where air flow occurs can be located between the first filter section (121) and the second filter section (122).

[0148] By the protruding movement of the blocking plate (13), the driving unit (211) is operated according to the control of the control unit, and the rotational movement of the principle separation unit can be achieved.

[0149] When the centrifugal separation unit (21) rotates, air is sucked in from the lower part of the open mounting structure (10), and the sucked air passes through the first filter part (121) and then passes through the air outlet (H16) located directly above the first filter part (121) and moves toward the exhaust structure (20).

[0150] Additionally, air sucked in from the lower part of the second filter section (122) can also be filtered by the second filter section (122) and, instead of moving upwards along the blocking plate (13) because it cannot pass through the blocking plate (13), it can move along the blocking plate (13) toward the air penetration section (16) of the hood case (11), pass through the air outlet (H16), and move toward the exhaust structure (20).

[0151] Accordingly, the air moved to the exhaust structure (20) rotates according to the rotational movement of the centrifugal separation unit (21), discharging foreign matter toward the housing (22), and can be discharged to the outside through the air outlet.

[0152] The technical features disclosed in each embodiment of the present invention are not limited to that embodiment only, and as long as they are not mutually incompatible, the technical features disclosed in each embodiment may be combined and applied to different embodiments.

[0153] Therefore, in each embodiment, the technical features are described primarily, but as long as the technical features are not mutually incompatible, they may be combined and applied together.
