[0098] Various components constituting the driving device (200) may be mounted on the frame (210). The frame (210) may be provided to support various components constituting the driving device (200). For example, a motor (220), a cam (230), a connecting rod (240), a moving member (250), a lever (260), an elastic member (270), and / or a switch (280) may be mounted on the frame (210).

[0099] The frame (210) may include a first insertion hole (2161). A coupler (300), which will be described later, may be inserted into the first insertion hole (2161). The first insertion hole (2161) may be formed on one side of the frame (210). For example, the first insertion hole (2161) may be formed by penetrating the front side wall (2102a) of the frame (210). The coupler (300) may be fixed by a fastening member while being inserted into the first insertion hole (2161). The coupler may be fixed to the frame (210) from the inside.

[0100] In the drawing, the frame (210) is depicted as including two first insertion holes (2161a, 2161b), but is not limited thereto. The number of first insertion holes (2161) may correspond to the number of cover members.

[0101] The frame (210) may include a second insertion hole (2162). An insertion protrusion (150) of a cover (100) to be described later may be inserted into the second insertion hole (2162). The second insertion hole (2162) may be formed on the other side of the frame (210). For example, the second insertion hole (2162) may be formed by penetrating the rear wall (2102b) of the frame (210). However, the present invention is not limited thereto, and a coupler (300) may also be inserted into the second insertion hole (2162). For example, both ends of the cover (100) along the length direction may be coupled to the frame (210) through the coupler (300).

[0102] In the drawing, the frame (210) is depicted as including two second insertion holes (2162a, 2162b), but is not limited thereto. The number of second insertion holes (2162) may correspond to the number of cover members described later.

[0103] Meanwhile, although it has been described above that the frame (210) is a component of the driving device (200), it is not limited thereto. The frame (210) may be provided as a separate component from the driving device (200).

[0104] The frame (210) may include position guide protrusions (217, 219). The position guide protrusions (217, 219) may guide the position of the lever (260). For example, the position guide protrusions (217, 219) may guide the position of the lever (260) in a first cover position (P1) where the cover (100) closes the suction port (12), or may guide the position of the lever (260) in a second cover position (P2) where the cover (100) opens the suction port (12). Since the lever (260) is interlocked with the coupler (300) and the moving member (250), the position guide protrusions (217, 219) may also guide the positions of the coupler (300) and the moving member (250).

[0105] The position guide protrusions (217, 219) may be provided in multiple numbers. The multiple position guide protrusions may include a first position guide protrusion (217) and a second position guide protrusion (219).

[0106] The first position guide protrusion (217) can guide the position of the lever (260) at the first cover position (P1) where the cover (100) closes the suction port (12). The first position guide protrusion (217) can come into contact with the lever (260) to prevent the lever (260) from rotating further upward. For example, the lower surface of the first position guide protrusion (217) and the upper surface of the lever (260) can come into contact.

[0107] The second position guide protrusion (219) can guide the position of the lever (260) at the second cover position (P2) where the cover (100) opens the suction port (12). The second position guide protrusion (219) can contact the lever (260) to prevent the lever (260) from rotating further downward. For example, the side surface of the second position guide protrusion (219) and the lower surface of the lever (260) can come into contact.

[0108] The driving device (200) may include a motor (220). The motor (220) may generate rotational force and / or power. The motor (220) may provide rotational force and / or power to a cam (230). The motor (220) may include a motor shaft (221). The motor shaft (221) may be coupled to and / or mounted to the cam (230).

[0109] The driving device (200) may include a cam (230). The cam (230) may be connected to a motor (220). The cam (230) may receive rotational force and / or power from the motor (220). The cam (230) may rotate in conjunction with the motor (220).

[0110] The cam (230) may include a cam coupling portion (232) that is coupled with the motor shaft (221) of the motor (220). For example, the cam coupling portion (232) may be provided at the center of the cam (230).

[0111] The cam (230) may include a cam shaft (231) that is spaced apart from the cam coupling portion (232). As the cam (230) connected to the motor (220) rotates, the cam shaft (231) may rotate about the cam coupling portion (232). As the cam (230) connected to the motor (220) rotates, the cam shaft (231) may rotate about the motor shaft (221).

[0112] The cam (230) may include at least one cam protrusion (233 and / or 234). As the cam (230) rotates, the at least one cam protrusion (233 and / or 234) may be arranged to contact a switch (280) to be described later. For example, the cam (230) may include a first cam protrusion (233) and a second cam protrusion (234). The first cam protrusion (233) and the second cam protrusion (234) may have different lengths.

[0113] The driving device (200) may include a connecting rod (240). The connecting rod (240) may be connected to a cam (230). The connecting rod (240) may be moved in conjunction with the cam (230). For example, the connecting rod (240) may be moved in a vertical direction (Z direction).

[0114] The first end (241) of the connecting rod (240) may be connected to the cam shaft (231). The first end (241) of the connecting rod (240) may rotate in conjunction with the cam shaft (231). The first end (241) of the connecting rod (240) may rotate together with the cam shaft (231). Therefore, the first end (241) of the connecting rod (240) may rotate around the motor shaft (221) of the motor (220). The first end (241) of the connecting rod (240) may be arranged to rotate around the motor shaft (221) of the motor (220). The first end (241) of the connecting rod (240) may rotate approximately in a circle.

[0115] The second end (242) of the connecting rod (240) can be moved in a vertical direction by the rotation of the first end (241) of the connecting rod (240). The second end (242) of the connecting rod (240) can be moved along a rail formed in the frame (210). The second end (242) of the connecting rod (240) can perform a linear reciprocating motion. The second end (242) of the connecting rod (240) can be connected to a moving member (250).

[0116] The driving device (200) may include a movable member (250). The movable member (250) may be movable in one direction. For example, the movable member (250) may be slidably moved in a vertical direction.

[0117] The moving member (250) may include a pressing portion (251). The pressing portion (251) may extend in one direction to press the lever (260). For example, the pressing portion (251) may extend in a horizontal direction to press the contact protrusion (261) of the lever (260) that is positioned below the pressing portion (251). The pressing portion (251) may come into contact with the contact protrusion (261). The pressing portion (251) may be provided above the moving member (252).

[0118] The pressurizing portion (251) may be provided in multiple forms. For example, the multiple pressurizing portions (251a, 251b) may include a first pressurizing portion (251a) and a second pressurizing portion (251b). The first pressurizing portion (251a) may extend horizontally. The second pressurizing portion (251b) may be rotatably coupled to the first pressurizing portion (251a). The second pressurizing portion (251b) may be coupled to both sides of the first pressurizing portion (251a).

[0119] Based on the operation of the motor (220), the pressing portion (251) of the moving member (250) can press the contact protrusion (261) of the lever (260). For example, when the cover (100) initially moves from the first cover position (P1) to the second cover position (P2), the first pressing portion (251a) can press the contact protrusion (261), and thereafter, the second pressing portion (251b) can press the contact protrusion (261).

[0120] The movable member (250) may further include a movable portion (252). The movable portion (252) may be positioned below the pressurizing portion (251). The movable portion (252) may extend vertically. The movable portion (252) may slide vertically. The movable portion (252) may be a sliding portion.

[0121] The movable member (250) may be connected to the second end (242) of the connecting rod (240). The movable member (250) may be movable in a vertical direction by being linked to the second end (242) of the connecting rod (240). The movable member (250) may be arranged to reciprocate linearly together with the second end (242) of the connecting rod (240). The movable member (250) may press the lever (260) as it moves in the vertical direction. The movable member (250) may be referred to as a slider (250), a movable panel (250), and / or a movable block (250).

[0122] The driving device (200) can convert rotational motion into linear reciprocating motion. For example, the motor (220), the cam (230), and the first end (241) of the connecting rod (240) can rotate. For example, the second end (242) of the connecting rod (240) and the moving member (250) can reciprocate linearly.

[0123] The driving device (200) may include a lever (260). The lever (260) may be pressed by the moving member (250). The lever (260) may be rotated as it is pressed by the moving member (250). The lever (260) may extend in one direction. For example, the lever (260) may extend in a horizontal direction. One end of the lever (260) along the longitudinal direction may be arranged to rotate about the other end of the lever (260).

[0124] The lever (260) can be coupled to the frame (210) from the outside of the frame (210). The lever (260) can be positioned on the opposite side of the coupler (300) with respect to the wall (2102a) of the frame (210).

[0125] The lever (260) can provide rotational force to the cover (100). The lever (260) can rotate the cover (100). The coupler (300) connecting the lever (260) and the cover (100) can transmit the rotational force of the lever (260) to the cover (100). The coupler (300) can be mounted on the lever (260). The lever (260) can be detachably coupled to the coupler (300) to transmit force to the coupler (300). The lever (260), the coupler (300), and the cover (100) can be arranged to rotate together. However, the lever (260) and the coupler (300) can be formed integrally to transmit the rotational force to the cover (100) or receive the rotational force from the cover (100).

[0126] The lever (260) can guide the rotation and movement of the cover (100) and / or the coupler (300). The lever (260) can be referred to as a guide link (260).

[0127] The lever (260) may include an extension (264). The extension (264) may extend in one direction. For example, while the cover (100) is in the first cover position (P1), the extension (264) may extend in the second direction (B1 or B2). Also, for example, while the cover (100) is in the second cover position (P2), the extension (264) may extend in the third direction (C).

[0128] The lever (260) may include a contact protrusion (261) that can contact the moving member (250). The contact protrusion (261) may extend and / or protrude from the extension (264). For example, the contact protrusion may protrude in the first direction (A). As the moving member (250) moves downward (-Z direction), the contact protrusion (261) may be contacted and pressed by the moving member (250).

[0129] The lever (260) may include a lever coupling portion (263) that can be coupled to the coupler (300). The lever coupling portion (263) may be referred to as a link coupling portion (263). The contact protrusion (261) of the lever (260) may be rotated about the lever coupling portion (263) by the pressing force of the moving member (250). The contact protrusion (261) of the lever (260) may be rotated approximately in an arc about the lever coupling portion (263). Accordingly, as the lever (260) is pressed and rotated by the moving member (250), the cover (100) may operate to open the suction port (12).

[0130] The lever (260) may include a moving projection (262) that moves along a path (2180) formed by the guide rib (218). The moving projection (262) may extend and / or protrude from the extension (264). For example, the moving projection (262) may protrude in a direction (D) opposite to the contact projection (261). The moving projection (262) may be arranged on the inside of the guide rib (218).

[0131] The movable protrusion (262) may be in contact with the elastic member (270). A second end (272) of the elastic member (270) may be positioned below the movable protrusion (262), and based on the movement of the movable protrusion (262), an elastic force may be generated in the elastic member (270). At this time, the elastic force generated in the elastic member (270) may be a force that returns the lever (260) to its original position. The movable protrusion (262) may fix and support the second end (272) of the elastic member (270). The movable protrusion (262) may be referred to as a support protrusion and / or a fixing protrusion.

[0132] The lever (260) may include a plurality of levers (260a, 260b). The plurality of levers (260a, 260b) may include a first lever (260a) and a second lever (260b). Each of the first lever (260a) and the second lever (260b) may include an extension portion (264), a contact protrusion (261), a lever engaging portion (263), and a moving protrusion (262).

[0133] In the drawing, the driving device (200) is depicted as including two levers (260a, 260b), but is not limited thereto. The number of levers (260) may correspond to the number of cover members described later.

[0134] The driving device (200) may include an elastic member (270). The elastic member (270) may be configured to elastically bias the cover (100) and / or the lever (260). The elastic member (270) may include a spring (270).

[0135] The elastic member (270) may be provided to elastically bias the lever (260) so that the lever (260) rotates in the opposite direction to the direction in which the lever (260) rotates when pressed by the movable member (250). In addition, the movable member (250) and the elastic member (270) may not be bound to each other. In addition, the cover (100) connected to the lever (260) via the coupler (300) may also rotate in conjunction with the lever (260).

[0136] For example, in response to the cover (100) rotating in the first rotational direction to open the suction port (12), the coupler (300) and the lever (260) can also rotate, and the elastic member (270) can press the lever (260) and the cover (100) in the second rotational direction to close the suction port (12).

[0137] In other words, the elastic member (270) can cause the cover (100) to rotate in a direction that covers and / or closes the suction port (12), regardless of the movement and position of the movable member (250). As the movable member (250) moves upward (-Z direction), the lever (260) may not be pressed by the movable member (250). The lever (260) that is not pressed by the movable member (250) can rotate in a direction that causes the cover (100) to close the suction port (12) due to the elastic restoring force of the elastic member (270). Accordingly, as the lever (260) rotates while being elastically biased by the elastic member (270), the cover (100) can operate to close the suction port (12).

[0138] The elastic member (270) may be configured to surround the wall (2163) of the frame (210) forming the first insertion hole (2161). The elastic member (270) may include a first end (271) and a second end (272). The first end (271) of the elastic member (270) may be restricted from moving by a support protrusion (213). For example, the first end (271) of the elastic member (270) may be in contact with the lower surface of the support protrusion (213). The second end (272) of the elastic member (270) may be in contact with the moving protrusion (262) of the lever (260). For example, the second end (272) of the elastic member (270) comes into contact with the lower surface of the movable projection (262) of the lever (260), and as the lever (260) rotates, the cover (100) also rotates, and an elastic force may be generated in the elastic member (270). Based on the rotation of the lever (260), a force may be generated in the elastic member (270) that returns the lever (260) and the cover (100) to their pre-rotation positions.

[0139] In other words, the movable member (250) does not press the cover (100) in the direction (upward) in which the cover (100) closes the suction port (12), and the elastic member (270) can press the lever in the direction (upward) in which the cover (100) closes the suction port (12). In addition, when a user presses the cover (100) downward to open the suction port (12), the cover (100), the lever (260), the coupler (300), and the elastic member (270) can rotate without the movable member (250) moving. In addition, the elastic member (270) can press the lever (260) in the direction in which the cover (100) closes the suction port (12).

[0140] Accordingly, even if the user's body is caught between the first cover member (100a) and the second cover member (100b), the user can pull the body out by pressing the first cover member (100a) and the second cover member (100b) downwards to increase the gap between the first cover member (100a) and the second cover member (100b). After pulling the body out, the first cover member (100a) and the second cover member (100b) can return to the first cover position (P1) by the elastic member (270). The cooking appliance according to one embodiment can prevent the user's body from being injured by being caught between the first cover member (100a) and the second cover member (100b).

[0141] In the drawing, the driving device (200) is depicted as including two elastic members (270a, 270b), but is not limited thereto. The number of elastic members (270) may be the same as the number of cover members described later.

[0142] In addition, although the plurality of elastic members (270a, 270b) are illustrated as including a first end (271a, 271b) and a second end (272a, 272b), the present invention is not limited thereto.

[0143] The driving device (200) may include a switch (280). The switch (280) may be positioned adjacent to the cam (230). The switch (280) may be configured to detect a rotational position of the cam (230). The switch (280) may be configured to contact at least one cam protrusion (233 and / or 234) of the cam (230). The switch (280) may be configured to be turned on / off upon contact with at least one cam protrusion (233 and / or 234) of the cam (230). The cooking appliance may determine the position of the cover (100) based on whether the switch (280) is turned on / off. For example, the control unit of the cooking appliance may determine whether the cover (100) opens the suction port (12) or closes the suction port (12). Although the drawing shows two switches (280), the present invention is not limited thereto. The switch (280) may be provided as one or as three or more.

[0144] The cooking device (1) may include a coupler (300). The coupler (300) may connect the driving device (200) and the cover (100). The coupler (300) may be configured to transmit power of the driving device (200) to the cover (100). The coupler (300) may be rotated by power generated by the driving device (200). The cover (100) coupled to the coupler (300) may be rotated together with the coupler (300). As a result, the cover (100) may operate to close or open the suction port (12).

[0145] One side of the coupler (300) can be coupled to the driving device (200), and the other side of the coupler (300) can be coupled to the cover (100).

[0146] The coupler (300) may include a shaft portion (331) that can be inserted into a first insertion hole (2161) of the frame (210). For example, the shaft portion (331) can be inserted into the first insertion hole (2161) in a first direction (A, see FIGS. 8 and 10). The shaft portion (331) can be inserted into the first insertion hole (2161) and connected to the lever (260). For example, an end portion (3311) of the shaft portion (331) can be detachably connected to a lever coupling portion (263) of the lever (260).

[0147] The coupler (300) may include a coupling protrusion (333). The coupling protrusion (333) of the coupler (300) may be detachably coupled with a coupling groove (140) of the cover (100) to be described later. The coupling protrusion (333) and the coupling groove (140) may have shapes corresponding to each other. The coupling protrusion (333) may extend and / or protrude from the shaft portion (331). The coupling protrusion (333) may extend and protrude in the left-right direction (e.g., Y, -Y) from the shaft portion (331). As will be described later, when the coupler (300) includes a shield portion (332), the coupling protrusion (333) may extend and protrude in the left-right direction (e.g., Y, -Y) from the shield portion (332). For example, the coupling protrusion (333) may extend from the shaft portion (331) in a second direction (B1 or B2, see FIG. 8) intersecting the first direction (A). For example, in the case of the coupler (300a), the coupling protrusion (333) may extend from the shaft portion (331) in a second direction (B1) intersecting the first direction (A). For example, in the case of the coupler (300b), the coupling protrusion (333) may extend from the shaft portion (331) in a second direction (B2) intersecting the first direction (A).

[0148] The coupling protrusion (333) may be provided to be rotatable around the shaft portion (331) inserted into the first insertion hole (2161). The coupling protrusion (333) may be rotated approximately in an arc around the shaft portion (331) inserted into the first insertion hole (2161).

[0149] The coupler (300) may include a fixing projection (334). The fixing projection (334) may allow the engaging projection (333) to be fixed within the engaging groove (140). The fixing projection (334) may be formed on the engaging projection (333). For example, the fixing projection (334) may protrude from one end of the engaging projection (333). The fixing projection (334) of the coupler (300) may be arranged to be caught in the engaging groove (160) of the cover (100). The fixing projection (334) of the coupler (300) may be arranged to be engaged with the engaging groove (160) of the cover (100). While the fixing projection (334) of the coupler (300) and the fixing groove (160) of the cover (100) are engaged, the cover (100) may not be easily separated from the coupler (300). While the fixing projection (334) of the coupler (300) and the fixing groove (160) of the cover (100) are engaged, the cover (100) may not be detached from the coupler (300). While the fixing projection (334) of the coupler (300) and the fixing groove (160) of the cover (100) are engaged, the cover (100) may not shake during the operation of opening or closing the suction port (12), and the cover (100) may be stably operated.

[0150] The connecting portion (120) of the cover (100) may include a groove forming portion (124). For example, the groove forming portion (124) may be formed in the second rib portion (122) to form a fixed groove (160). The groove forming portion (124) may include a protrusion.

[0151] The coupler (300) may include a shield portion (332). The shield portion (332) may extend from the shaft portion (331). For example, the shield portion (332) may be provided between the shaft portion (331) and the coupling protrusion (333). The shield portion (332) may be provided to cover the first insertion hole (2161). The shield portion (332) may be larger than the first insertion hole (2161). The shield portion (332) may have a larger size than the first insertion hole (2161). For example, the diameter of the shield portion (332) may be larger than the diameter of the first insertion hole (2161). The first insertion hole (2161) into which the coupler (300) is inserted may be sealed. Accordingly, air flowing in the euro (210f) can be prevented from leaking out through the first insertion hole (2161). Air guided by the frame (210) can be prevented from leaking out through the first insertion hole (2161). Consequently, contaminants contained in the air can be prevented from penetrating into the internal space (13c) of the case (13), various components of the driving device (200), etc.

[0152] The coupler (300) may include a plurality of couplers (300a, 300b). The plurality of couplers (300a, 300b) may include a first coupler (300a) and a second coupler (300b). Each of the first coupler (300a) and the second coupler (300b) may include a shaft portion (331), a shield portion (332), a coupling protrusion (333), and a fixing protrusion (334).

[0153] In the drawing, the cooking device (1) is depicted as including two couplers (300a, 300b), but is not limited thereto. The number of couplers (300) may be the same as the number of cover members described later.

[0154] A cooking appliance (1) may include a cover (100). The cover (100) may include at least one cover member (100a and / or 100b). The cover members (100a, 100b) may extend in one direction, and for example, may extend longer in the one direction than in the width direction. For example, the cover members (100a, 100b) may extend in the horizontal direction. For example, the cover members (100a, 100b) may extend in the front-back direction.

[0155] In the drawing, the cover (100) is illustrated as including a first cover member (100a) and a second cover member (100b), and the first cover member (100a) and the second cover member (100b) are arranged approximately along the horizontal direction (Y direction), but is not limited thereto. For example, the cover (100) may include one cover member, and in this case, one cover member may have a size corresponding to the suction port (12). For example, the first cover member (100a) and the second cover member (100b) may be arranged approximately along the front-back direction (X direction). For example, the cover (100) may include three or more cover members. The cover members may be provided in various numbers, shapes, and / or arrangements. Hereinafter, for convenience of explanation, an example in which the cover (100) includes a first cover member (100a) and a second cover member (100b) will be described.

[0156] In the drawing, reference symbols for the configuration of the first cover member (100a) and / or the configuration corresponding to the first cover member (100a) may be indicated with "a". In the drawing, reference symbols for the configuration of the second cover member (100b) and / or the configuration corresponding to the second cover member (100b) may be indicated with "b". For example, the lever (260a), the coupler (300a), the elastic member (270a), the first insertion hole (2161a), the second insertion hole (2162a), etc. may be provided to correspond to the first cover member (100a). For example, the lever (260b), the coupler (300b), the elastic member (270b), the first insertion hole (2161b), the second insertion hole (2162b), etc. may be provided to correspond to the second cover member (100b).

[0157] The first cover member (100a) and the second cover member (100b) may be provided symmetrically. The first cover member (100a) and the second cover member (100b) may be provided symmetrically with respect to the vertical center line (V) of the suction port (12). The first cover member (100a) and the second cover member (100b) may have substantially the same shape.

[0158] Hereinafter, the description of either the first cover member (100a) or the second cover member (100b) may be applied to the description of the other of the first cover member (100a) or the second cover member (100b). Hereinafter, the description of the cover (100) may be applied to both the first cover member (100a) and the second cover member (100b). Hereinafter, for convenience of explanation, the description of the cover (100) may be replaced with the description of each cover member.

[0159] The cover (100) can be detachably connected to the coupler (300). The coupler (300) can be inserted into the cover (100) or withdrawn from the cover (100). The cover (100) can be linked to the coupler (300) to close the suction port (12) or open the suction port (12). The cover (100) can be rotated together with the coupler (300). As the coupler (300) is rotated by the driving device (200), the cover (100) connected to the coupler (300) can also be rotated.

[0160] The cover (100) may include a cover panel (110). The cover panel (110) may be provided to correspond to the suction port (12). The cover panel (110) may have an extended shape to cover the suction port (12). For example, the cover panel (110) may extend in the front-rear direction.

[0161] For example, the cover panel (110) may have a roughly plate shape. For example, the cover panel (110) may include a first edge portion (111), a second edge portion (112), a third edge portion (113), and a fourth edge portion (114). For example, the first edge portion (111) and the second edge portion (112) may be provided as long sides. For example, the third edge portion (113) and the fourth edge portion (114) may be provided as short sides. For example, the third edge portion (113) may be provided on a side adjacent to the lever (260) of the driving device (200). For example, the fourth edge portion (114) may be provided on an opposite side of the third edge portion (113). For example, the cover panel (110) may have a shape that is long in the front-back direction (X direction) and short in the horizontal direction (Y direction). However, it is not limited to the above-described example, and the cover panel (110) may have various shapes.

[0162] The cover (100) may include a first cover extension (120). The first cover extension (120) may extend from the cover panel (110). The first cover extension (120) may extend from a first side of the cover panel (110). For example, the first cover extension (120) may extend from a third edge portion (113) of the cover panel (110). For example, the first cover extension (120) may extend from the third edge portion (113) in a third direction (C) intersecting the first direction (A) and the second direction (B). For example, the first cover extension (120) may extend downward from one end along the longitudinal direction of the cover panel (110).

[0163] The cover (100) may include a coupling portion (120). For example, the first cover extension portion (120) may be the coupling portion (120). The coupling portion (120) may allow the coupler (300) and the cover (100) to be coupled. The coupling portion (120) may include a coupling groove (140). For example, the coupling groove (140) may be formed in the first cover extension portion (120). The coupler (300) may be coupled and / or inserted into the coupling groove (140). The coupling groove (140) of the cover (100) may be detachably coupled to the coupling protrusion (333) of the coupler (300). The coupling groove (140) of the cover (100) may have a shape corresponding to the coupling protrusion (333) of the coupler (300). For example, the joining groove (140) of the cover (100) may extend along the extension direction of the third edge portion (113) of the cover panel (110).

[0164] Although it has been described that a coupling portion (120) including a coupling groove (140) is provided in the cover (100) and a coupler (300) is inserted into the coupling groove (120), it is not limited thereto. The coupler (300) may include a coupling groove, and a coupling portion protruding from the cover (100) may be provided so as to be inserted into the coupler (300).

[0165] The first cover extension (120) may include a first rib portion (121) adjacent to the cover panel (110). The first cover extension (120) may include a second rib portion (122) spaced apart from the first rib portion (121). The second rib portion (122) may be spaced apart from the first rib portion (121) with a joining groove (140) therebetween. The second rib portion (122) may be spaced apart from the first rib portion (121) in a third direction (C). The first cover extension (120) may include a third rib portion (123) connecting the first rib portion (121) and the second rib portion (122). The first cover extension (120) may be referred to as a joining portion (120) forming a joining groove (140).

[0166] The joining groove (140) may include a first groove (141) that is provided to be surrounded by a first rib (121), a second rib (122), and a third rib (123). The joining groove (140) may include a second groove (142) that is provided to be open on an opposite side to the first groove (141). For example, the second groove (142) may correspond to a portion of the joining groove (140) that is not surrounded by the first rib (121), the second rib (122), and the third rib (123). The area of ​​the second groove (142) may increase as it goes in the second direction. For example, the joining groove (140) may include an approximately U-shape.

[0167] The cover (100) may include a guide (180). The coupling portion (120) may include a guide (180). The guide (180) may guide the coupling of the coupler (300) to the coupling portion (120). For example, the guide (180) may guide the insertion of the coupler (300) into the coupling groove (140). The guide (180) may be provided adjacent to the second groove portion (142). The guide (180) may be positioned farther from the third rib portion (123) than from the first rib portion (121), the second rib portion (122), the slit portion (170), and the first groove portion (141). The guide (180) may be inclined or tapered so that the area of ​​the second groove portion (142) increases as it moves in the second direction from the second groove portion (142). Since the guide (180) is formed to be tapered, the coupler (300) can be easily inserted into and separated from the cover (100) through the guide (180). The guide (180) can be a coupling guide, an insertion guide, an inlet guide, a withdrawal guide, and / or a separation guide.

[0168] The width (d2) of the second groove (142) may be longer than the width (d1) of the first groove (141). For example, the area of ​​the second groove (142) may be larger than the area of ​​the first groove (141). The coupler may be first inserted into the second groove (142) and then inserted into the first groove (141). Therefore, it may be easy for the coupler (300) to be inserted into the coupling groove (140) of the cover (100).

[0169] The cover (100) may include a fixing groove (160). The fixing groove (160) of the cover (100) may be provided so that the fixing projection (334) of the coupler (300) is caught therein. The fixing groove (160) may have a shape corresponding to the fixing projection (334). The fixing groove (160) may be provided so as to communicate with the coupling groove (140). For example, the fixing groove (160) may be formed as the second rib portion (122) is sunken in. The fixing groove (160) may also be included in the coupling groove (140).

[0170] The cover (100) may include a slit portion (170). The slit portion (170) may be formed by cutting a portion of the first cover extension portion (120). The slit portion (170) may allow a portion of the first cover extension portion (120) to be elastically deformed. For example, the slit portion (170) may be provided between the second rib portion (122) and the coupling groove (140) so that the second rib portion (122) may be elastically deformed relative to the coupling groove (140). For example, as force is applied to the second rib portion (122), the size of the second groove portion (242) of the coupling groove (140) may change.

[0171] The cover (100) may include a second cover extension (130). The second cover extension (130) may extend from the cover panel (110). The second cover extension (130) may extend from a second side of the cover panel (110). For example, the second cover extension (130) may extend from a fourth edge portion (114) of the cover panel (110). For example, the second cover extension (130) may extend from the fourth edge portion (114) in a third direction (C) intersecting the first direction (A) and the second direction (B). The second cover extension (130) may be arranged on an opposite side of the first cover extension (120) with respect to the cover panel (110). The second cover extension (130) may be arranged to face the first cover extension (120).

[0172] The cover (100) may include an insertion protrusion (150). The insertion protrusion (150) may be formed on the second cover extension (130). The insertion protrusion (150) may protrude from the second cover extension (130). The insertion protrusion (150) may be inserted into the second insertion hole (2162) of the frame (210). For example, the insertion protrusion (150) may be inserted into the second insertion hole (2162) in a fourth direction (D) opposite to the first direction (A).

[0173] Fig. 13 illustrates an example of a state in which the cover is in the first cover position in a cooking appliance according to one embodiment. Fig. 14 is a cross-sectional view of a cooking appliance according to one embodiment. Fig. 15 is a cross-sectional view of a cooking appliance according to one embodiment. Fig. 16 illustrates an example of a state in which the cover is in the second cover position in a cooking appliance according to one embodiment. Fig. 17 is a cross-sectional view of a cooking appliance according to one embodiment.

[0174] Fig. 14 is a cross-sectional view taken along line A-A' of Fig. 13. Fig. 15 is a cross-sectional view taken along line B-B' of Fig. 13. Fig. 17 is a cross-sectional view taken along line C-C' of Fig. 15.

[0175] Referring to FIGS. 13 to 17, the cover (100) may be rotatable and / or movable between a position (first cover position, P1) that covers and / or closes the suction port (12) and a position (second cover position, P2) that opens the suction port (12). In addition, since the coupler (300) is linked with the cover (100), the coupler (300) may be rotatable and / or movable between a first coupler position (P1') corresponding to the first cover position (P1) and a second coupler position (P2') corresponding to the second cover position (P2).

[0176] The cover (100) can rotate in conjunction with the coupler (300). While the coupling protrusion (333) of the coupler (300) and the coupling groove (140) of the cover (100) are coupled, the cover (100) can close the suction port (12) or open the suction port (12) in conjunction with the coupler (300). While the coupling protrusion (333) of the coupler (300) and the coupling groove (140) of the cover (100) are coupled, the cover (100) can be arranged to rotate together with the coupler (300) as the coupling protrusion (333) of the coupler (300) rotates around the shaft portion (331) of the coupler (300). The coupling groove (140) of the cover (100) coupled to the coupling protrusion (333) of the coupler (300) may be configured to rotate around the shaft portion (331) of the coupler (300). The shaft portion (331) of the coupler (300) may be configured to form a rotational axis of the cover (100). The shaft portion (331) may be referred to as a rotational shaft.

[0177] Referring to FIGS. 13 to 15, while the cover (100) is in the first cover position (P1) that closes the intake port (12), the cover (100) may be restricted from moving upward due to interference from the coupler (300). For example, while the cover (100) is in the position (P1) that closes the intake port (12), the cover (100) may not be separated from the coupler (300). At this time, the coupler (300) may be in the first coupler position (P1').

[0178] For example, while the coupling protrusion (333) and the coupling groove (140) are coupled and the cover (100) is at a position (P1) where the suction port (12) is closed, the coupling protrusion (333) may be positioned above the second rib portion (122). Accordingly, even if a user attempts to lift the cover (100), the cover (100) may not be detached from the coupler (300) as the second rib portion (122) and the coupling protrusion (333) interfere with each other.

[0179] In addition, since the movement of the moving projection (262) is restricted and guided by the guide rib (218), while the cover (100) is at the first cover position (P1), the moving projection (262) cannot move further upward by the guide rib (218) provided on the upper side. Accordingly, the cover (100) can be prevented from moving upward at the first cover position (P1).

[0180] Referring to FIGS. 16 and 17, while the cover (100) is in a position (P2) that opens the suction port (12), the cover (100) may be provided to be detachable upwardly from the coupler (300). For example, while the cover (100) is in a second cover position (P2) that opens the suction port (12), the cover (100) may be detachable from the coupler (300). At this time, the coupler (300) may be in a second coupler position (P2').

[0181] For example, while the engaging projection (333) and engaging groove (140) are engaged and the cover (100) is at a position (P2) where the suction port (12) is opened, the second groove portion (142) of the engaging groove (140) may face downward. Accordingly, when a user attempts to lift the cover (100), the cover (100) may not be prevented from moving upward by the coupler (300) and at least one rib portion (121, 122 and / or 123). For example, when a user lifts the cover (100), the engaging groove (140) of the cover (100) moves upward, and the engaging projection (333) of the coupler (300) may come out of the engaging groove (140) through the second groove portion (142) and the guide (180).

[0182] Fig. 18 is a perspective view of a cooking appliance according to one embodiment. Fig. 19 is a perspective view of a cooking appliance according to one embodiment.

[0183] Fig. 18 illustrates an example of a state in which the coupling groove of the cover is separated from the coupling protrusion of the coupler in a cooking appliance according to one embodiment. Fig. 19 illustrates an example of a state in which the insertion protrusion of the cover is separated from the frame in a cooking appliance according to one embodiment.

[0184] Referring to FIGS. 18 and 19, an example of a cover (100) being separated from a coupler (300) will be described.

[0185] While the cover (100) is in a position to open the suction port (12), the cover (100) can be separated from the coupler (300). The engaging groove (140) of the cover (100) can be separated from the engaging protrusion (333) of the coupler (300) (see FIG. 18). For example, as the first cover extension (120) of the cover (100) moves upward, the engaging groove (140) of the cover (100) can be separated from the engaging protrusion (333) of the coupler (300). For example, as the second groove (142) increases in size due to elastic deformation of the second rib (122), the first cover extension (120) of the cover (100) can be moved upward. Next, the insertion protrusion (150) of the cover (100) can be separated from the second insertion hole (2162) of the frame (120) (see FIG. 19). For example, by moving the cover (100) in the first direction (A, see FIG. 10) opposite to the fourth direction (D, see FIG. 10), the insertion protrusion (150) can be separated from the second insertion hole (1262). With the insertion protrusion (150) detached from the second insertion hole (2162), the second cover extension (130) of the cover (100) can be moved upward.

[0186] Fig. 20 is a schematic diagram of a cooking appliance according to one embodiment. Fig. 21 is a schematic diagram of a cooking appliance according to one embodiment.

[0187] Referring to FIGS. 20 and 21, the process of coupling the cover (100) to the coupler (300) may be performed in the reverse order of the process described in FIGS. 17 to 19. For example, the insertion protrusion (150) of the cover (100) may be inserted into the second insertion hole (1262), and then the coupling groove (140) of the cover (100) may be coupled to the coupling protrusion (333) of the coupler (300).

[0188] For example, while the coupler (300) is at the second coupler position (P2'), the cover (100) and the coupler (300) can be coupled. The cover (100) can be moved downward so that the coupling protrusion (333) is inserted into the coupling groove (140). As the cover (100) moves downward, the first end (333a, e.g., the upper end) of the coupler (300) can be first inserted into the second groove (142) having a larger area than the first groove (141), and then inserted into the first groove (141). While the coupler (300) is inserted into the coupling groove (140), the fixing protrusion (333) of the coupler (300) can be inserted into the fixing groove (160).

[0189] In addition, the home forming portion (124) can have a predetermined angle (b1), and the fixing protrusion (334) can also have a predetermined angle (a1). In addition, the second end (333b, e.g., the lower end) of the engaging protrusion (333) can also have a predetermined angle (a2). For example, the home forming portion (124), the fixing protrusion (334), and the second end (333b) of the engaging protrusion (333) can have predetermined angles (a1, a2, b1) with respect to the horizontal direction and / or the vertical direction. For example, while the coupler (300) is at the second coupler position (P2') and the cover (100) is at the second cover position (P2), the home forming portion (124), the fixing protrusion (334), and the second end (333b) of the engaging protrusion (333) can have predetermined angles (a1, a2, b1) with respect to the horizontal direction. Additionally, for example, while the coupler (300) is at the first coupler position (P1') and the cover (100) is at the first cover position (P1), the home forming portion (124), the fixing protrusion (334), and the second end (333b) of the coupling protrusion (333) may have a predetermined angle (a1, a2, b1) with respect to the vertical direction.

[0190] However, the home forming portion (124), the fixing protrusion (334), and the second end (333b) of the engaging protrusion (333) may not all have an angle, but only one may have an angle. For example, only the home forming portion (124) may have a predetermined angle (b1), only the second end (333b) of the engaging protrusion (333) may have a predetermined angle (a2), or only the fixing protrusion (334) may have a predetermined angle (a1).

[0191] Accordingly, since the second end (333b) of the coupling protrusion (333) and the fixing protrusion (334) can be supported by the groove forming portion (124), after the coupler (300) is inserted into the coupling groove (140) of the coupling portion (120), the fixing protrusion (334) is inserted and fixed within the fixing groove (160), so that the coupler (300) cannot easily fall out from the coupling portion (120). For example, the predetermined angles (a1, a2, b1) of the groove forming portion (124), the fixing protrusion (334), and the second end (333b) of the coupling protrusion (333) can be 10 degrees or more.

[0192] Additionally, the guide (180) may have a predetermined angle (b2). For example, the guide (180) may have a predetermined angle (b2) with respect to the horizontal direction and / or the vertical direction. For example, while the coupler (300) is at the second coupler position (P2') and the cover (100) is at the second cover position (P2), the guide (180) may have a predetermined angle (b2) with respect to the horizontal direction. Additionally, for example, while the coupler (300) is at the first coupler position (P1') and the cover (100) is at the first cover position (P1), the guide (180) may have a predetermined angle (b2) with respect to the vertical direction.

[0193] FIG. 22 is a schematic diagram of a cooking appliance according to one embodiment. FIG. 23 is a schematic diagram of a cooking appliance according to one embodiment. FIG. 24 is a schematic diagram of a cooking appliance according to one embodiment. FIG. 25 is a schematic diagram of a cooking appliance according to one embodiment. FIG. 26 is a schematic diagram of a cooking appliance according to one embodiment. FIG. 27 is a schematic diagram of a cooking appliance according to one embodiment.

[0194] Referring to FIGS. 22 to 27, while the coupler (300) is at the first coupler position (P1'), the cover (100) and the coupler (300) can be coupled. The cover (100) can be moved downward so that the coupling protrusion (333) can be inserted into the coupling groove (140). Since the coupler (300) is at the first coupler position (P1'), the cover (100) can be slightly tilted and inserted into the second groove (142). For example, the cover (100) can be positioned between the first cover position (P1) and the second cover position (P2). At this time, the second groove (142) can be formed wide due to the guide (180) having an incline or tapering.

[0195] Referring to FIGS. 23 and 24, the inclination of the guide (180) can guide the insertion of the coupling protrusion (333) into the second groove (142). During the process of inserting the coupler (300) into the second groove (142), the cover (100) and the coupler (300) can be slightly tilted and inserted into the second groove (142). For example, the coupler (300) can be positioned between the first coupler position (P1') and the second coupler position (P2').

[0196] Referring to FIGS. 25 to 27, after the coupling protrusion (333) is inserted into the second groove (142), the cover (100) can be moved downward toward the first groove (141). While the coupler (300) is inserted into the coupling groove (140), the fixing protrusion (334) of the coupler (300) can be inserted into the fixing groove (160).

[0197] The cover (100) can be easily coupled to or detached from the coupler (300). The cover (100) is not directly connected to the driving device (200), but can be connected to the driving device (200) via the coupler (300). When detaching or removing the cover (100) from the cooking device (1), there is no need to disassemble the entire cooking device (1) or the driving device (200). Only the cover (100) can be disassembled or removed separately from the cooking device (1). Accordingly, cleaning and / or maintenance of the cover (100) is easy. Consequently, the usability of the cooking device (1) can be improved.

[0198] According to one aspect of the present disclosure, a cooking appliance can be provided in which the cover can be easily detached, so that the filter can be introduced and withdrawn through the suction port, thereby enabling cleaning of the filter.

[0199] The effects according to one aspect of the present disclosure are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by a person having ordinary skill in the art to which the present disclosure pertains from the description below.

[0200] A cooking appliance according to one aspect comprises: a plate (11) on which a cooking vessel can be placed and on which an intake port (12) is formed; a fan (51) disposed below the plate and configured to suck air through the intake port; a cover (100) configured to open and close the intake port; a motor (220) configured to drive the cover; and a coupler (300) coupleable to the cover to transmit power from the motor to the cover; wherein the cover comprises a coupling portion (120) coupleable to the coupler, and the coupling portion may include a tapered guide (180) at one end of the coupling portion to guide the coupler to be inserted into the cover.

[0201] The above-mentioned coupling portion includes a coupling groove (140) extending in one direction so that the coupler can be inserted; the coupling groove includes a first end (141) along the longitudinal direction of the coupling groove; and a second end (142) along the longitudinal direction of the coupling groove, the second end being opened so that the coupler can be inserted; and the guide can be inclined from the first end to the second end so that the area of ​​the second end is larger than the area of ​​the first end.
