[0094] The frame (210) may have a shape in which the upper and / or lower portions are generally open. The frame (210) may include an opening (2101) corresponding to the intake port (12). The frame (210) may include a side wall (2102) to form a flow path (210f). For example, the side wall (2102) may include a front side wall (2102a), a rear side wall (2102b), a right side wall (2102c), and a left side wall (2102d). For example, at least a portion of the side wall (2102) may partition the flow path (210f) and the internal space (13c) of the case (13).
[0095] The frame (210) can be mounted on the cooktop (10). For example, the frame (210) can be fixed to the plate (11) and / or the bottom (13a) of the case (13) (see FIG. 7).
[0096] 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).
[0097] 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.
[0098] 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.
[0099] 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 according to one embodiment, 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).
[0100] 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.
[0101] 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).
[0102] 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).
[0103] 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).
[0104] 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.
[0105] 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.
[0106] 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).
[0107] 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).
[0108] 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).
[0109] 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).
[0110] 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.
[0111] 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).
[0112] 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.
[0113] 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).
[0114] 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.
[0115] 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).
[0116] 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). However, the pressurizing portion (251) may only be provided with the first pressurizing portion (251a).
[0117] 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). Since the second pressing portion (251b) is rotatably coupled to the first pressing portion (251a), it may not impede or interfere with the rotation of the lever (260) including the contact protrusion (261) (see FIGS. 20 and 21).
[0118] 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.
[0119] 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).
[0120] 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.
[0121] 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).
[0122] 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).
[0123] 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).
[0124] 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).
[0125] 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).
[0126] 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).
[0127] 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).
[0128] 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).
[0129] 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.
[0130] 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).
[0131] 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.
[0132] 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).
[0133] 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).
[0134] 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).
[0135] 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).
[0136] 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.
[0137] 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).
[0138] 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).
[0139] 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.
[0140] 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.
[0141] 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.
[0142] 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).
[0143] 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).
[0144] 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).
[0145] 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).
[0146] 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).
[0147] The coupler (300) may include a fixing projection (334). The fixing projection (334) may be fixed within the engaging projection (333) 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 engaging 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 operated stably.
[0148] 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.
[0149] 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.
[0150] 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).
[0151] 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.
[0152] 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. For example, the cover members (100a, 100b) may extend in a horizontal direction. For example, the cover members (100a, 100b) may extend in a front-back direction.
[0153] The cover (100) may include a first cover member (100a) and a second cover member (100b). For example, the first cover member (100a) and the second cover member (100b) may be arranged in the Y direction (e.g., left-right direction). The first cover member (100a) may cover a part of the suction port (12), and the second cover member (100b) may cover another part of the suction port (12). In addition, the first cover member (100a) may open and close a part of the suction port (12), and the second cover member (100b) may open and close another part of the suction port (12).
[0154] 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 this 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. In addition, the cover member may include cover members 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.
[0155] 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).
[0156] 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.
[0157] 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.
[0158] 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.
[0159] 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.
[0160] 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.
[0161] 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).
[0162] 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).
[0163] In one embodiment, a coupling portion (120) including a coupling groove (140) is provided in the cover (100), and a coupler (300) is described as being inserted into the coupling groove (120). However, this is not limited thereto, and 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).
[0164] 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).
[0165] 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.
[0166] 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 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.
[0167] 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).
[0168] 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).
[0169] 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.
[0170] 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).
[0171] 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).
[0172] 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 illustrates an example of a state in which the cover is in the second cover position in a cooking appliance according to one embodiment.
[0173] Referring to FIGS. 13 and 14, the cover (100) is 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).
[0174] 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, as the coupling protrusion (333) of the coupler (300) rotates around the shaft portion (331) of the coupler (330), the cover (100) can be arranged to rotate together with 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.
[0175] 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).
[0176] 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.
[0177] In addition, since the movement of the moving protrusion (262) is restricted and guided by the guide rib (219), while the cover (100) is at the first cover position (P1), the moving protrusion (262) cannot move further upward by the guide rib (219) provided on the upper side. Accordingly, the cover (100) can be prevented from moving upward at the first cover position (P1).
[0178] 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).
[0179] 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. Thus, 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).
[0180] While the cover (100) is moved from the first cover position (P1) to the second cover position (P2), the pressing portion (251) of the moving member (250) can press the contact protrusion (261) of the lever (260). For example, when the rotation angle of the cover (100) is small, the first pressing portion (251a) can press the contact protrusion (261), and as the rotation angle of the cover (100) increases, the second pressing portion (251b) can press the contact protrusion (261). However, when only the first pressing portion (251a) is provided as the pressing portion (251), as the rotation angle of the cover (100) increases, the rounded portions (251aa) provided at both ends of the first pressing portion (251a) can press the contact protrusion (261).
[0181] FIG. 15 is a front view of a cooking device according to one embodiment. FIG. 16 is an enlarged view of a cooking device according to one embodiment. FIG. 17 is an enlarged view of a cooking device according to one embodiment. FIG. 18 is an enlarged view of a cooking device according to one embodiment. FIG. 19 is an enlarged view of a cooking device according to one embodiment. FIG. 20 is an enlarged view of a cooking device according to one embodiment. FIG. 21 is an enlarged view of a cooking device according to one embodiment.
[0182] Figures 15 to 17 illustrate the first cover member (100a) and the second cover member (100b) before they are rotated. Figure 17 illustrates the cooking appliance with the slider (250) omitted for explanation. Figure 18 illustrates that only the first cover member (100a) is rotated. For example, Figure 18 illustrates that the first cover member (100a) is rotated by about 5 degrees. Figures 19 to 21 illustrate that the first cover member (100a) and the second cover member (100b) are rotated. For example, FIG. 19 illustrates that the first cover member (100a) is rotated about 15 degrees and the second cover member (100b) is rotated about 5 degrees, FIG. 20 illustrates that the first cover member (100a) and the second cover member (100b) are rotated about 50 degrees, and FIG. 21 illustrates that the first cover member (100a) and the second cover member (100b) are rotated about 80 degrees.
[0183] However, the rotation angles of the first cover member (100a) and the second cover member (100b) in FIGS. 16 to 21 are merely examples, and the values of the rotation angles illustrated in FIGS. 16 to 21 may vary depending on the vertical lengths of the first cover member (100a) and the second cover member (100b). For example, if the vertical lengths of the first cover member (100a) and the second cover member (100b) become larger, the angles illustrated in FIGS. 16 to 20 may become larger.
[0184] The extension (264a) of the first lever (260a) may be referred to as a first extension (264a), and the extension (264b) of the second lever (260b) may be referred to as a second extension (264b). The contact projection (261a) of the first lever (260a) may be referred to as a first contact projection (261a), and the contact projection (261b) of the second lever (260b) may be referred to as a second contact projection (261b). The moving projection (262a) of the first lever (260a) may be referred to as a first moving projection (262a), and the moving projection (262b) of the second lever (260b) may be referred to as a second moving projection (262b).
[0185] Referring to FIGS. 16 and 17, the first lever (260a) and the second lever (260b) may have different widths. The width (L1) of the first extension portion (264a) along one direction and the width (L2) of the second extension portion (264b) along one direction may be different. For example, at the first cover position (P1) of the cover (100), the length (L1) of the first extension portion (264a) along the vertical direction and the length (L2) of the second extension portion (264b) along the vertical direction may be different. For example, at the first cover position (P1) of the cover (100), the length (L1) of the first extension portion (264a) along the vertical direction may be smaller than the length (L2) of the second extension portion (264b) along the vertical direction. In other words, the length (L2) of the second extension (264b) along the vertical direction at the first cover position (P1) of the cover (100) may be greater than the length (L1) of the first extension (264a) along the vertical direction. In addition, the length (L2) of the second extension (264b) along the horizontal direction at the second cover position (P2) of the cover (100) may be greater than the length (L1) of the first extension (264a) along the horizontal direction.
[0186] While the cover (100) is in the first cover position (P1), the first contact protrusion (261a) may be positioned above the second contact protrusion (261b). While the cover (100) is in the first cover position (P1), the second contact protrusion (261b) may be positioned below the first contact protrusion (261a) while the cover (100) is in the first cover position (P1). For example, the second contact protrusion (261b) may be positioned lower than the second lever (260b). While the cover (100) is in the first cover position (P1), the center (C1) of the first contact protrusion (261a) may be positioned above the center (C2) of the second contact protrusion (261b). While the cover (100) is at the first cover position (P1), the center (C2) of the second contact protrusion (261b) may be positioned lower than the center (C1) of the first contact protrusion (261a).
[0187] The pressurizing portion (251) includes a first pressurizing portion (251a), and the first pressurizing portion (251a) may include a rounding portion (251aa). The first pressurizing portion (251a) may extend in one direction. For example, the first pressurizing portion (251a) may extend in the Y direction. The rounding portion (251aa) may be provided at both ends of the first pressurizing portion (251a) along the extension direction and / or the longitudinal direction. The rounding portion (251aa) may be formed by rounding on the lower surface and / or both side surfaces of the first pressurizing portion. The rounding portion (251aa) may be formed adjacent to the rotation coupling portion (251ab).
[0188] The first pressurizing portion (251a) may include a rotational coupling portion (251ab). The rotational coupling portion (251ab) may be formed at both ends of the first pressurizing portion (251a) along the longitudinal direction. The second pressurizing portion (251b) may be rotatably coupled to the rotational coupling portion (251ab). The second pressurizing portion (251b) may be rotatably coupled to the first pressurizing portion (251a) so as to prevent the pressurizing portion (251) from interfering with or hindering the rotation of the contact protrusion (261) as the cover (100) and the contact protrusion (261) rotate.
[0189] However, the pressurizing portion (251) may only be provided with the first pressurizing portion (251a), and the first pressurizing portion (251a) may not include the rotational coupling portion (251ab). In the case where the pressurizing portion (251) is provided with only the first pressurizing portion (251a), as the rotation angle of the cover (100) and the contact protrusion (261) increases, the rounding portions (251aa) provided at both ends of the first pressurizing portion (251a) can press the contact protrusion (261), and the contact protrusion (261) can rotate along the rounding portion (251aa). As the contact protrusion (261) is pressed by the rounding portion (251aa), the cover (100) can rotate.
[0190] Referring to FIG. 18, in response to the motor (220) being driven, one (100a, 100b) of the plurality of cover members (100a, 100b) may rotate before the other cover members (100a, 100b). The plurality of cover members (100a, 100b) may rotate sequentially. For example, in response to the motor (220) being driven, the first cover member (100a) may rotate before the second cover member (100b). For example, the first cover member (100a) may rotate at least 5 degrees before the second cover member (100b).
[0191] In response to the motor (220) being driven, the slider (250) can move downward. Since the first contact protrusion (261a) is positioned above the second contact protrusion (261b), the pressing portion (251) of the slider (250) can press the first contact protrusion (261a) downward before the second contact protrusion (261b). At this time, the pressing portion (251) may not press the second contact protrusion (261b). For example, the first pressing portion (251a) may press the first contact protrusion (261a) and not press the second contact protrusion (261b). As the first contact protrusion (261a) is pressed, the first cover member (100a) coupled to the first lever (260a) and the first coupler (300a) can be rotated in a direction that opens the suction port (12). Based on the rotation of the first cover member (100a), a portion of the suction port (12) can be opened.
[0192] Since the first cover member (100a) and the second cover member (100b) do not rotate simultaneously, the first cover member (100a) and the second cover member (100b) can be prevented from colliding and / or interfering with each other due to the rotation radius. Since the collision and / or interference between the first cover member (100a) and the second cover member (100b) can be prevented, the gap between the first cover member (100a) and the second cover member (100b) at the first cover position (P1) of the cover can be minimized. Since the gap between the first cover member (100a) and the second cover member (100b) at the first cover position (P1) of the cover is minimized, the aesthetics of the cooking appliance can be improved.
[0193] Referring to Fig. 19, in response to the motor (220) being driven, the slider (250) can be moved downward. The pressurizing portion (251) can press the first contact protrusion (261a) and the second contact protrusion (261b) downward. As the first contact protrusion (261a) and the second contact protrusion (261b) are pressed, the first cover member (100a) coupled to the first lever (260a) and the first coupler (300a) and the second cover member (100b) coupled to the second lever (260b) and the second coupler (300b) can be rotated in a direction that opens the suction port (12). At this time, the first cover member (100a) may be rotated more than the second cover member (100b). For example, the first pressurizing portion (251a) can simultaneously pressurize the first contact protrusion (261a) and the second contact protrusion (261b).
[0194] Referring to FIGS. 20 and 21, in response to the motor (220) being driven, the slider (250) can move downward, so that the pressurizing portion (251) can press the first contact protrusion (261a) and the second contact protrusion (261b) downward. As the first contact protrusion (261a) and the second contact protrusion (261b) are pressed, the first cover member (100a) and the second cover member (100b) can be rotated to fully open the suction port (12). As the rotation angle of the first cover member (100a) and the second cover member (100b) increases, the second pressurizing portion (251b) can press the first contact protrusion (261a) and the second contact protrusion (261b) (see FIG. 21).
[0195] In FIGS. 15 to 21, it has been described that the first cover member (100a) rotates first and then the second cover member (100b) rotates based on the rotation of the motor (220). However, it is also possible for the second cover member (100b) to rotate first and then the first cover member (100a) to rotate. In addition, it is also possible for the motor (220) not to rotate and for the user to pressurize multiple cover members (100a, 100b) to open the suction port (12).
[0196] 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.
[0197] Referring to Fig. 22, the cover (100) may include a first cover member (100a) and a second cover member (100b). The first cover member (100a) and the second cover member (100b) may be arranged in a horizontal direction to open and close the suction port (12).
[0198] The first cover member (100a) may include an inclined portion (100aa). The inclined portion (100aa) of the first cover member (100a) may be referred to as a first inclined portion (100aa). For example, the first inclined portion (100aa) may protrude downward toward the second cover member (100b). The first inclined portion (100aa) may be provided on a side opposite to the rotational axis of the first cover member (100a). For example, the rotational axis of the first cover member (100a) may be positioned at one end along the -Y direction, and the first inclined portion (100aa) may be positioned at one end along the Y direction.
[0199] The second cover member (100b) may include an inclined portion (100ba). The inclined portion (100ba) of the second cover member (100b) may be referred to as a second inclined portion (100ba). For example, the second inclined portion (100ba) may protrude upward toward the first cover member (100a). The second inclined portion (100ba) may be provided on a side opposite to the rotational axis of the second cover member (100b). For example, the rotational axis of the second cover member (100b) may be positioned at one end along the Y direction, and the second inclined portion (100ba) may be positioned at one end along the -Y direction.
[0200] The first inclined portion (100aa) and the second inclined portion (100ba) may correspond to each other. The direction in which the first inclined portion (100aa) and the second inclined portion (100ba) are inclined is not limited to the above-described example. For example, the first inclined portion (100aa) may protrude toward the second cover member (100b) as it goes upward, or the second inclined portion (100ba) may protrude toward the first cover member (100a) as it goes downward.
[0201] Based on the rotation of the motor (220), the first cover member (100a) and the second cover member (100b) can be rotated. For example, the first cover member (100a) and the second cover member (100b) can be rotated simultaneously. Since the first inclined portion (100aa) and the second inclined portion (100ba) correspond to each other and have an inclined portion, even if the first cover member (100a) and the second cover member (100b) are rotated simultaneously, the first cover member (100a) and the second cover member (100b) may not collide and / or interfere with each other. Since the collision and / or interference between the first cover member (100a) and the second cover member (100b) does not occur, the gap between the first cover member (100a) and the second cover member (100b) can be minimized, and the aesthetics of the cooking appliance can be improved.
[0202] Figure 23 is a schematic diagram of a cooking appliance according to one embodiment.
[0203] Referring to Fig. 23, the cover (100) may include a first cover member (100a) and a second cover member (100b). The first cover member (100a) and the second cover member (100b) may be arranged in a horizontal direction to open and close the suction port (12).
[0204] The first cover member (100a) may include a body (101a) and a protrusion (102a). The body (101a) and the protrusion (102a) of the first cover member (100a) may be referred to as the first body (101a) and the first protrusion (102a). The first body (101a) may cover most of the suction port (12) covered by the first cover member (100a). The first protrusion (102a) may protrude from the first body (101a) toward the second cover member (100b). The first protrusion (102a) may be positioned below the second protrusion (102b).
[0205] The second cover member (100b) may include a body (101b) and a protrusion (102b). The body and the protrusion (102b) of the second cover member (100b) may be referred to as a second body (102a) and a second protrusion (102b). The second body (102a) may cover most of the suction port (12) covered by the second cover member (100b). The second protrusion (102b) may protrude from the second body (102a) toward the first cover member (100a). The second protrusion (102b) may be disposed above the first protrusion (102a).
[0206] The first body (101a) may be larger than the first protrusion (102a). For example, the first protrusion (102a) may be provided in a small size so as not to collide with and / or interfere with the second protrusion (102b) while the first cover member (100a) and the second cover member (100b) rotate. The second body (101b) may be larger than the second protrusion (102b). For example, the second protrusion (102b) may be provided in a small size so as not to collide with and / or interfere with the first protrusion (102a) while the first cover member (100a) and the second cover member (100b) rotate.
[0207] The first protrusion (102a) and the second protrusion (102b) can correspond to each other.
[0208] Based on the rotation of the motor (220), the first cover member (100a) and the second cover member (100b) can be rotated. For example, the first cover member (100a) and the second cover member (100b) can be rotated simultaneously. Since the first protrusion (102a) and the second protrusion (102b) correspond to each other, even if the first cover member (100a) and the second cover member (100b) are rotated simultaneously, the first cover member (100a) and the second cover member (100b) may not collide and / or interfere with each other. Since the collision and / or interference between the first cover member (100a) and the second cover member (100b) does not occur, the gap between the first cover member (100a) and the second cover member (100b) can be minimized, and the aesthetics of the cooking appliance can be improved.
