Ventilation module and cooking appliance including same

[0001] Embodiments of the present disclosure relate to a ventilation module and a cooking appliance including the same.

[0002] Hoods, which typically draw in contaminated air or smoke generated during cooking and exhaust it to the outside, are placed above heating appliances, such as induction or gas ranges.

[0003] Recently, considering space utilization and design aspects, products have been released that do not mount the hood on top of the heating device, but place the hood on the heating device itself or adjacent to the heating device.

[0004] A cooking appliance according to one embodiment of the present disclosure may include a heating module configured to heat and cook food, and a ventilation module including an intake port for sucking cooking smoke generated during cooking of the food downward.

[0005] The ventilation module may include a suction chamber having the suction port positioned at the top and first and second oil filters mounted opposite each other at the bottom of the suction port.

[0006] The ventilation module may further include an exhaust chamber disposed on one side of the suction chamber, having a blower fan provided therein to generate a flow for suction, and providing at least a portion of a direct path for a portion of cooking smoke sucked through the suction port to pass through the first oil filter and move toward the blower fan.

[0007] The ventilation module may further include a bypass chamber disposed on the other side of the suction chamber and providing at least a portion of a bypass path through which the remainder of the cooking smoke sucked through the suction port passes through the second oil filter and moves toward the blower fan.

[0008] The ventilation module may include at least one deodorizing filter configured to filter a portion of the cooking smoke traveling along the direct path and to filter a remainder of the cooking smoke traveling along the bypass path.

[0009] A ventilation module according to one embodiment of the present disclosure extracts cooking smoke from a cooking appliance, and may include a suction chamber having an upper portion of the suction port and first and second oil filters mounted opposite to each other at a lower portion of the suction port.

[0010] The ventilation module may further include an exhaust chamber disposed on one side of the suction chamber, having a blower fan provided therein to generate a flow for suction, and providing at least a portion of a direct path for a portion of cooking smoke sucked through the suction port to pass through the first oil filter and move toward the blower fan.

[0011] The ventilation module may further include a bypass chamber disposed on the other side of the suction chamber and providing at least a portion of a bypass path through which the remainder of the cooking smoke sucked through the suction port passes through the second oil filter and moves toward the blower fan.

[0012] The ventilation module may include at least one deodorizing filter configured to filter a portion of the cooking smoke traveling along the direct path and to filter a remainder of the cooking smoke traveling along the bypass path.

[0036] Hereinafter, a cooking appliance and a ventilation module used therein according to various embodiments will be specifically described with reference to the drawings.

[0037] FIG. 1 is a perspective view showing an example of an installed cooking device (1) according to one embodiment of the present disclosure, FIG. 2 is an assembled perspective view showing a cooking device (1) according to one embodiment, and FIG. 3 is an exploded perspective view showing an exploded cooking device (1) according to one embodiment.

[0038] Referring to FIGS. 1 to 3, a cooking device (1) according to an embodiment may include a heating module (10) configured to heat and cook food, and a ventilation module (100) configured to inhale cooking smoke (S) generated when cooking food. The cooking device (1) may further include a control module (20) that controls the operation of the heating module (10). The cooking device (1) may be placed in an island-shaped sink, as shown in FIG. 1.

[0039] The heating module (10) is positioned at the top of the cooking appliance (1) and generates high-temperature heat to heat the food itself or a dish containing the food. For example, the heating module (10) may be an induction module with a flat upper surface and driven by electricity. The heating module (10) may also be a module other than an induction module, for example, a gas range module.

[0040] For example, a heating module (10) may include a top plate (11), at least one heating element (12, 13) disposed on the lower portion of the top plate (11), and a housing (14) in which the heating element (12, 13) is disposed inside. Heat generated from the heating element (12, 13) may be transferred to food through the top plate (11).

[0041] At least one heating element (12, 12) may include a plurality of heating elements (12, 13) arranged to be spaced apart from each other. However, the number of heating elements (12, 13) does not necessarily have to be multiple and may be a single heating element as needed.

[0042] The ventilation module (100) may include an intake port (1101) configured to intake cooking smoke (S) in a downward direction (a direction opposite to the Z direction, hereinafter referred to as the “-Z direction”). The ventilation module (100) may further include a shutter (112) for opening and closing the intake port (1101). The ventilation module (100) may further include a blower fan (180) for generating a flow for intake of cooking smoke (S) through the intake port (1101). The ventilation module (100) may further include an outlet port (1211) through which air passing through the blower fan (180) is discharged.

[0043] The suction port (1101) may be arranged on the side of the heating module (10). For example, the suction port (1101) may be arranged between a plurality of heating elements (12, 13). The suction port (1101) of the ventilation module (100) may be arranged to penetrate the heating module (10). The suction port (1101) may be arranged in the opening (15) of the upper plate (11) of the heating module (10) and the opening (16) of the housing (14). However, the arrangement of the suction port (1101) is not necessarily limited thereto and may be modified in various ways.

[0044] A part of the ventilation module (100), for example, an intake port (1101), may be disposed on the side of the heating module (10), and another part of the ventilation module (100), for example, a blower fan (180), may be disposed on the lower part of the heating module (10). The blower fan (180) may be disposed on the lower part of a heating element (12) of the heating module (10). The control module (20) may be disposed on the lower part of another heating element (13) of the heating module (10).

[0045] The blower fan (180) may be a centrifugal fan designed to suck in cooking smoke (S) in a vertical direction and discharge cooking smoke (S) in a lateral direction. For example, the blower fan (180) may have an intake port (181) provided at the top and an exhaust port (182) provided at the side. For example, the blower fan (180) may be a sirocco fan. The exhaust port (182) of the blower fan (180) may be connected to the exhaust port (1211) of the ventilation module (100). However, the type of the blower fan (180) is not limited thereto and may be modified in various ways.

[0046] Fig. 4 is an assembled perspective view showing a ventilation module (100) according to one embodiment, and Fig. 5 is an exploded perspective view of the ventilation module (100) of Fig. 4.

[0047] Referring to FIGS. 4 and 5, a ventilation module (100) according to an embodiment may include a plurality of chambers provided to allow cooking smoke (S) introduced through an intake port (1101) to move. The ventilation module (100) may include a suction chamber (110), an exhaust chamber (120), and a bypass chamber (130). The suction chamber (110), the exhaust chamber (120), and the bypass chamber (130) may be arranged in a horizontal direction perpendicular to the vertical direction (Z direction). For example, the suction chamber (110), the exhaust chamber (120), and the bypass chamber (130) may be arranged in the X direction, which is one of the horizontal directions.

[0048] The suction chamber (110) has a suction port (1101) positioned at the top, and may be equipped with multiple oil filters inside. The oil filter may be a filter for removing oil during cooking. The oil filter may be referred to as a grease filter. The suction chamber (110) may include a separate frame (111) defining the suction port (1101).

[0049] A plurality of oil filters may be mounted so as to be detachable. The plurality of oil filters may include first and second oil filters (141, 142) provided at the lower portion of the intake (1101).

[0050] The first and second oil filters (141, 142) may be arranged to face each other. The first and second oil filters (141, 142) may be arranged to be spaced apart from each other. However, the arrangement of the first and second oil filters (141, 142) is not necessarily limited to this, and may be arranged in various structures as long as they are arranged to face each other. For example, the first and second oil filters (141, 142) may be provided as an integrated structure having a structure to face each other.

[0051] Each of the first and second oil filters (141, 142) may be positioned so as to face the discharge chamber (120) and the bypass chamber (130). In other words, the first oil filter (141) may be positioned so as to face the discharge chamber (120), and the second oil filter (142) may be positioned so as to face the bypass chamber (130).

[0052] The first and second oil filters (141, 142) may be arranged obliquely with respect to the vertical direction. For example, the first and second oil filters (141, 142) may be arranged so that the distance between them becomes closer as they get farther away from the intake port (1101).

[0053] The first and second oil filters (141, 142) can be placed in the path of cooking smoke (S) introduced through the intake port (1101). The first and second oil filters (141, 142) can remove the flexibility of the introduced cooking smoke (S).

[0054] The exhaust chamber (120) may be arranged on one side of the suction chamber (110). For example, as shown in FIG. 4, the exhaust chamber (120) may be arranged on the right side of the suction chamber (110). The exhaust chamber (120) may be arranged in a direction perpendicular to the direction in which cooking smoke (S) is introduced through the suction port (1101) of the suction chamber (110). The exhaust chamber (120) and the suction chamber (110) may be arranged in a horizontal direction.

[0055] The exhaust chamber (120) may be provided with a blower fan (180) inside that creates a flow for suction inside the ventilation module (100). As the blower fan (180) operates, cooking smoke (S) is sucked in through the suction port (1101), and the cooking smoke (S) may move toward the intake port (181) of the blower fan (180).

[0056] A portion of the cooking smoke (S) sucked into the suction chamber (110) through the suction port (1101) may move to the exhaust chamber (120). The exhaust chamber (120) may provide at least a portion of a direct path (P1) through which a portion of the cooking smoke (S) passes through the first oil filter (141) and moves toward the blower fan (180).

[0057] Considering the size of the blower fan (180), the size of the exhaust chamber (120) may be larger than the sizes of the other chambers. The size of the exhaust chamber (120) may be larger than the size of the suction chamber (110). The planar size of the exhaust chamber (120) may be larger than the planar size of the suction chamber (110). The volume of the exhaust chamber (120) may be larger than the volume of the suction chamber (110). The size of the exhaust chamber (120) may be larger than the size of the bypass chamber (130). The planar size of the exhaust chamber (120) may be larger than the planar size of the bypass chamber (130). The volume of the exhaust chamber (120) may be larger than the volume of the bypass chamber (130). The size of the exhaust chamber (120) may be larger than the sum of the sizes of the suction chamber (110) and the bypass chamber (130).

[0058] The bypass chamber (130) may be arranged on the other side of the suction chamber (110). The bypass chamber (130) may be arranged in a direction perpendicular to the direction in which cooking smoke (S) is introduced through the suction port (1101) of the suction chamber (110). The bypass chamber (130) and the suction chamber (110) may be arranged in a horizontal direction. The bypass chamber (130), the suction chamber (110), and the discharge chamber (120) may be arranged in a horizontal direction. A portion of the bypass chamber (130) may be arranged on the opposite side of the discharge chamber (120) with the suction chamber (110) interposed therebetween. Another portion of the bypass chamber (130) may be connected to the discharge chamber (120) so that the cooking smoke (S) moving through the other side of the suction chamber (110) moves to the discharge chamber (120).

[0059] The bypass chamber (130) may provide at least a portion of a bypass path (P2) through which the remainder of the cooking smoke (S) sucked in through the intake port (1101) passes through the second oil filter (142) and moves toward the blower fan (180). The bypass chamber (130) may include a first bypass region (131) that changes the direction of movement of the cooking smoke (S) that has passed through the second oil filter (142) and a second bypass region (132) that changes the direction of movement of the cooking smoke (S) that has passed through the first bypass region (131) so as to direct it toward the exhaust chamber (120).

[0060] Since the bypass chamber (130) is intended to provide a bypass path (P2) for cooking smoke (S), the size of the bypass chamber (130) may be smaller than the size of the exhaust chamber (120). The flow rate of cooking smoke (S) moving through the bypass path (P2) may be greater than the flow rate of cooking smoke (S) moving through the direct path (P1).

[0061] The ventilation module (100) may further include at least one deodorizing filter. The deodorizing filter may filter cooking smoke (S) from which oil or grease has been removed by the first and second oil filters (141, 142). The deodorizing filter may be a filter for removing volatile organic compounds contained in the cooking smoke (S).

[0062] The deodorizing filter may be configured to filter a portion of the cooking smoke (S) traveling along the direct path (P1) and to filter the remainder of the cooking smoke (S) traveling along the bypass path (P2).

[0063] The deodorizing filter and the blower fan (180) may be arranged horizontally. The deodorizing filter and the blower fan (180) may be arranged vertically and in a direction perpendicular to the vertical direction. By arranging the blower fan (180) and the deodorizing filter horizontally, the vertical height of the ventilation module (100) may be reduced. For example, the vertical height of the ventilation module (100) may be no more than three times the vertical height of the blower fan (180). For example, the vertical height of the ventilation module (100) may be no more than 2.5 times the vertical height of the blower fan (180).

[0064] Deodorizing filters may be activated carbon or ceramic filters. However, the types of deodorizing filters are not limited to these, and any filter that can be used for deodorizing purposes may be freely modified.

[0065] The deodorizing filter may include a first deodorizing filter (160) disposed on one side of the suction chamber (110). At least a portion of the first deodorizing filter (160) may be disposed between the suction chamber (110) and the discharge chamber (120). The first deodorizing filter (160) may include a first deodorizing region (161) and a second deodorizing region (162). The first deodorizing region (161) may be provided to filter cooking smoke (S) traveling along a direct path (P1). For example, the first deodorizing region (161) may be provided between the suction chamber (110) and the discharge chamber (120). At least a portion of the second deodorizing region (162) may be provided to filter cooking smoke (S) traveling along a bypass path (P2). For example, the second deodorizing region (162) may be provided between the bypass chamber (130) and the discharge chamber (120). For example, a part of the second deodorization area (162) may be disposed between the bypass chamber (130) and the exhaust chamber (120), and another part of the second deodorization area (162) may be disposed between the suction chamber (110) and the exhaust chamber (120). A part of the second deodorization area (162) may filter cooking smoke (S) traveling along the bypass path (P2), and another part may filter cooking smoke (S) traveling along the direct path (P1).

[0066] The first deodorizing filter (160) may have a structure corresponding to the external shape of the blower fan (180). For example, the first deodorizing filter (160) may become narrower as it approaches the blower fan (180). The first deodorizing region (161) may become narrower as it approaches the blower fan (180) along the round external shape of the blower fan (180). The second deodorizing region (162) may become narrower as it approaches the blower fan (180) along the round external shape of the blower fan (180). In this way, since the first deodorizing filter (160) has a structure corresponding to the external shape of the blower fan (180), the size occupied by the first deodorizing filter (160) in the ventilation module (100) can be reduced, and accordingly, the size of the blower fan (180), which is directly related to ventilation performance, can be increased.

[0067] The first deodorizing region (161) and the second deodorizing region (162) of the first deodorizing filter (160) may be configured as separate bodies. For example, the first deodorizing region (161) and the second deodorizing region (162) may be individually mounted and separated. However, the configuration of the first deodorizing filter (160) is not limited thereto and may vary. For example, the first deodorizing region (161) and the second deodorizing region (162) may be configured as one body or as separate bodies. For example, the first deodorizing filter (160) may be configured as one body with the first deodorizing region (161) and the second deodorizing region (162).

[0068] The deodorizing filter may further include a second deodorizing filter (170) disposed on the other side of the suction chamber (110). The second deodorizing filter (170) may be disposed between the suction chamber (110) and the bypass chamber (130). The second deodorizing filter (170) may be disposed between the suction chamber (110) and the first bypass area (131) of the bypass chamber (130).

[0069] The second deodorizing filter (170) may be configured to filter cooking smoke (S) moving along the bypass path (P2). The second deodorizing filter (170) may be positioned on the bypass path (P2). The second deodorizing filter (170) may be mounted separately from the first deodorizing filter (160).

[0070] The second deodorizing filter (170) may have a different shape from the first deodorizing filter (160). For example, the second deodorizing filter (170) may have at least one of a height in the vertical direction and a length in the horizontal direction different from the first deodorizing filter (160). For example, the first deodorizing filter (160) and the second deodorizing filter (170) may have different lengths. For example, the first deodorizing filter (160) and the second deodorizing filter (170) may have different lengths in the Y direction. For example, the length of the second deodorizing filter (170) may be shorter than the length of the first deodorizing filter (160). In other words, the length of the first deodorizing filter (160) may be longer than the length of the second deodorizing filter (170). As another example, although not shown, the first deodorizing filter (160) and the second deodorizing filter (170) may have different heights in the vertical direction (Z).

[0071] The second deodorizing filter (170) may be made of the same material as the first deodorizing filter (160). The second deodorizing filter (170) may filter cooking smoke (S) moving along the bypass path (P2).

[0072] Meanwhile, although not shown in the drawing, the ventilation module (100) may further include a dust collection filter. For example, a dust collection filter may be placed between the oil filter and the deodorizing filter. Through the dust collection filter, the dust collection performance of the ventilation module (100) can be improved.

[0073] FIG. 6 is a cross-sectional view taken vertically through a cooking device (1) according to one embodiment, and FIG. 7 is a cross-sectional view taken horizontally through a cooking device (1) according to one embodiment.

[0074] Referring to FIGS. 6 and 7, in the cooking device (1) according to the embodiment, cooking smoke (S) can be introduced in a downward direction (-Z direction) through an intake port (1101). The cooking smoke (S) introduced in a downward direction (-Z direction) can branch and move to a direct path (P1) and a bypass path (P2) in the suction chamber (110).

[0075] Some of the cooking smoke (S) may be filtered by the first deodorizing area (161) of the first deodorizing filter (160) as it moves directly along the euro (P1).

[0076] The remainder of the cooking smoke (S) can be primarily filtered by the second deodorizing filter (170) while moving along the bypass path (P2). The cooking smoke (S) that has passed through the second deodorizing filter (170) can be secondarily filtered by the second deodorizing region (162) of the first deodorizing filter (160). In this way, the filtering performance of the ventilation module (100) can be improved by filtering a portion of the cooking smoke (S) twice without increasing the thickness of the first deodorizing filter (160).

[0077] As described above, in the ventilation module (100) according to the embodiment, the cooking smoke (S) introduced through the intake port (1101) moves toward the blower fan (180) through parallel paths such as the direct path (P1) and the bypass path (P2). Accordingly, when the resistance of the first deodorizing filter (160) increases while the cooking smoke (S) passes through the direct path (P1), the amount of the cooking smoke (S) passing through the second deodorizing filter (170) can naturally increase. Through this, even if the resistance of the first deodorizing filter (160) increases, the air volume of the ventilation module (100) can be prevented from rapidly decreasing. Accordingly, the ventilation module (100) according to the embodiment can lower the filter differential pressure and improve the filter performance compared to the ventilation module (100) without the bypass path (P2).

[0078] The air volume of the cooking smoke (S) flowing from the suction chamber (110) to the discharge chamber (120) may be different from the air volume flowing from the suction chamber (110) to the bypass chamber (130). The air volume of the cooking smoke (S) flowing from the suction chamber (110) to the discharge chamber (120) may be greater than the air volume flowing from the suction chamber (110) to the bypass chamber (130). The air volume of the cooking smoke (S) moving along the direct path (P1) may be greater than the air volume of the cooking smoke (S) moving along the bypass path (P2).

[0079] FIG. 8 is a plan view of a cooking device (1) according to one embodiment viewed from above, and FIG. 9 is a cross-sectional view of a cooking device (1) according to one embodiment cut in an up-down direction.

[0080] The ventilation module (100) according to the embodiment can determine the size of the intake port (1101) and the size of the bypass chamber (130) by taking into consideration the size and air volume.

[0081] Referring to Fig. 8, in the cooking device (1) according to the embodiment, the planar size may be limited. Accordingly, the sum of the planar sizes of the suction chamber (110) and the bypass chamber (130) of the ventilation module (100) may be determined. For example, the sum of the length (L1) of the suction port (1101) and the length of the bypass chamber (130) may be determined. The sum of the length (L1) of the suction port (1101) and the length (L2) of the second bypass area (132) of the bypass chamber (130) may be limited. The sum of the length (L1) of the suction port (1101) and the length (L2) of the second bypass area (132) of the bypass chamber (130) may be 500 mm or less.

[0082] Within this limited size range, when the length (L1) of the suction port (1101) is increased, the length (L2) of the first bypass region (131) may decrease. When the length (L1) of the suction port (1101) increases, the amount of air flowing in through the suction port (1101) increases, whereas when the length (L2) of the second bypass region (132) decreases, the amount of air flowing into the bypass chamber (130) may decrease. Taking this into consideration, the length (L1) of the suction port (1101) and the length (L2) of the second bypass region (132) can be designed within a predetermined range.

[0083] For example, the ratio of the length (L1) of the suction port (1101) to the length (L2) of the second bypass region (132) may be 2:1 to 20:1. For example, the ratio of the length (L1) of the suction port (1101) to the length (L2) of the second bypass region (132) may be 2:1 to 10.4:1. For example, the ratio of the length (L1) of the suction port (1101) to the length (L2) of the second bypass region (132) may be 2:1 to 10:1.

[0084] The length (L1) of the suction port (1101) may be 200 mm to 400 mm. The length (L2) of the second bypass region (132) may be 20 mm to 150 mm. The length (L1) of the suction port (1101) may be 225.5 mm to 310 mm. The length (L2) of the second bypass region (132) may be 30 mm to 114.5 mm.

[0085] In addition, in the ventilation module (100) according to the embodiment, the arrangement of the blower fan (180) can be determined by considering the wind volume.

[0086] For example, considering the air volume of the ventilation module (100), the blower fan (180) can determine the distance (D) from the side where the exhaust port (1211) is provided in the exhaust chamber (120). For example, the distance (D) from the center of rotation of the blower fan (180) and the side where the exhaust port (1211) is provided in the exhaust chamber (120) may be 150 mm to 200 mm. For example, the distance (D) from the center of rotation of the blower fan (180) and the side where the exhaust port (1211) is provided in the exhaust chamber (120) may be 170 mm to 200 mm. For example, the distance (D) from the center of rotation of the blower fan (180) and the side where the exhaust port (1211) is provided in the exhaust chamber (120) may be 180 mm to 190 mm.

[0087] Referring to FIG. 9, for example, the distance (G) between the intake port (181) of the blower fan (180) and the upper surface (122) of the exhaust chamber (120) can be determined by considering the airflow of the ventilation module (100). For example, the distance (G) between the intake port (181) of the blower fan (180) and the upper surface (122) of the exhaust chamber (120) can be 35 mm to 50 mm. For example, the distance (G) between the intake port (181) of the blower fan (180) and the upper surface (122) of the exhaust chamber (120) can be 41 mm to 50 mm. The upper surface (122) of the exhaust chamber (120) can be defined by the heating module (10). For example, the upper surface (122) of the exhaust chamber (120) can be defined by the lower surface of the housing (14) of the heating module (10). The vertical height of the exhaust chamber (120) may be less than twice the vertical height of the blower fan (180).

[0088] Meanwhile, in the above-described embodiment, the deodorizing filter of the ventilation module (100) was described with an example including a first deodorizing filter (160) and a second deodorizing filter (170), but the configuration and arrangement of the deodorizing filter are not necessarily limited thereto.

[0089] FIG. 10 is a drawing for explaining a modified example of a deodorizing filter in a ventilation module (100) according to one embodiment, and FIG. 11 is a drawing for explaining a modified example of a deodorizing filter in a ventilation module (100) according to one embodiment.

[0090] Referring to FIG. 10, the ventilation module (100) according to the embodiment may be equipped with only the first deodorizing filter (160) and may not be equipped with the second deodorizing filter (170). In other words, the second deodorizing filter (170) in the ventilation module (100) may be an optional component of the ventilation module (100). For example, when the suction pressure by the blower fan (180) is low, only the first deodorizing filter (160) may be equipped in the ventilation module (100). Even if only the first deodorizing filter (160) is mounted on the ventilation module (100) without the second deodorizing filter (170), cooking smoke (S) moving along the direct path (P1) can be filtered by the first deodorizing area (161) of the first deodorizing filter (160), and cooking smoke (S) moving along the bypass path (P2) can be filtered by the second deodorizing area (162) of the first deodorizing filter (160). In this way, even if the second deodorizing filter (170) is not mounted, since cooking smoke (S) is filtered by the first deodorizing filter (160), a rapid decrease in filtering efficiency can be prevented.

[0091] Referring to Fig. 11, the deodorizing filter of the ventilation module (100) according to the embodiment may include a first deodorizing filter (160A) and a second deodorizing filter (170). The first deodorizing filter (160A) may have different performances in the first deodorizing region (161) and the second deodorizing filter (170). For example, the materials of the first deodorizing region (161) and the second deodorizing region (162) may be different. For example, the first deodorizing region (161) may have excellent removal performance for a first odor, and the second deodorizing region (162) may have excellent removal performance for a second odor that is different from the first odor.

[0092] Fig. 12 is a simplified drawing of the configuration of a ventilation module (100) according to one embodiment. Fig. 13 is a simplified drawing of the configuration of a ventilation module (100) according to another embodiment.

[0093] Referring to FIG. 12, the ventilation module (100) according to the embodiment may have a bypass chamber (130) connected to the second deodorization area (162) of the first deodorization filter (160), as in the above-described embodiments. Accordingly, the bypass path (P2) may extend past the second deodorization filter (170), past the second deodorization area (162) of the first deodorization filter (160), and to the blower fan (180). However, the design of the bypass path (P2) of the ventilation module (100) is not necessarily limited thereto.

[0094] Referring to FIG. 13, in the ventilation module (100) according to the embodiment, a bypass flow path (P2) may be connected between the first oil filter (141) and the first deodorizing filter (160). Accordingly, a portion of the cooking smoke (S) introduced through the suction chamber (110) may move along the direct flow path (P1) to the first oil filter (141) and the first deodorizing filter (160) and then to the blower fan (180). The remainder of the cooking smoke (S) introduced through the suction chamber (110) may move along the bypass flow path (P2) to the second oil filter (142), the second deodorizing filter (170), and the first deodorizing filter (160) and then to the blower fan (180).

[0095] Meanwhile, in the above-described examples, cooking smoke (S) is exemplified as smoke generated during cooking, but is not necessarily limited thereto. For example, cooking smoke (S) can be understood as a broad concept that includes polluted indoor air.
