[0098] 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).

[0099] 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) having a different length than the first cam protrusion (233).

[0100] 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 arranged to move in conjunction with the cam (230).

[0101] 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). Accordingly, 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.

[0102] The second end (242) of the connecting rod (240) may be provided to be movable in the vertical direction (Z direction) by the rotation of the first end (241) of the connecting rod (240). The second end (242) of the connecting rod (240) may be provided to move along a rail formed in the frame (210). The second end (242) of the connecting rod (240) may be provided to perform a linear reciprocating motion. The second end (242) of the connecting rod (240) may be connected to a movable member (250).

[0103] The driving device (200) may include a movable member (250). The movable member (250) may be connected to a second end (242) of a connecting rod (240). The movable member (250) may be arranged to be movable in a vertical direction (Z direction) by being linked to the second end (242) of the connecting rod (240). The movable member (250) may be arranged to perform a linear reciprocating motion together with the second end (242) of the connecting rod (240). The movable member (250) may be arranged to pressurize a guide link (260) as it moves in the vertical direction (Z direction). The movable member (250) may be referred to as a movable panel (250) or a movable block (250).

[0104] The driving device (200) may be configured to 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) may be configured to rotate. For example, the second end (242) of the connecting rod (240) and the moving member (250) may be configured to reciprocate linearly.

[0105] The driving device (200) may include a guide link (260). The guide link (260) may be configured to be pressed by the moving member (250). The guide link (260) may be configured to rotate as it is pressed by the moving member (250). One end of the guide link (260) may be configured to rotate about the other end of the guide link (260).

[0106] The guide link (260) can provide rotational force to the cover (100). The guide link (260) can be arranged to rotate the cover (100). The guide link (260) can be detachably coupled to the holder (300). The holder (300) connecting the guide link (260) and the cover (100) can be arranged to transmit the rotational force of the guide link (260) to the cover (100). The guide link (260), the holder (300), and the cover (100) can be arranged to rotate together.

[0107] For example, the guide link (260) may include a lever (261) provided to come into contact with the movable member (250). For example, the guide link (260) may include a link engaging portion (263) that can be coupled to the holder (300). As the movable member (250) moves downward (-Z direction), the lever (261) of the guide link (260) may be pressed by the movable member (250). The lever (261) of the guide link (260) may be provided to rotate about the link engaging portion (263) by the pressing force of the movable member (250). The lever (261) of the guide link (260) may be provided to rotate approximately in an arc about the link engaging portion (263). Accordingly, as the guide link (260) is pressed by the movable member (250) and rotates, the cover (100) can operate to open the suction port (12).

[0108] In the drawing, the driving device (200) is depicted as including two guide links (260a, 260b), but the present disclosure is not limited thereto. The number of guide links (260) may be the same as the number of cover members described later.

[0109] The driving device (200) may include a spring (270). The spring (270) may be provided to elastically bias the cover (100). The spring (270) may be provided to elastically bias the guide link (260) so that the guide link (260) rotates in a direction opposite to the direction in which the guide link (260) rotates when pressed by the movable member (250). Accordingly, the cover (100), which is connected to the guide link (260) through the holder (300), may also rotate in conjunction with the guide link (260). Accordingly, the cover (100) may rotate to cover the suction port (12). As the movable member (250) moves upward (-Z direction), the guide link (260) may not be pressed by the movable member (250). The guide link (260), which is not pressurized by the movable member (250), can rotate by the elastic restoring force of the spring (270). Accordingly, as the guide link (260) rotates while being elastically biased by the spring (270), the cover (100) can operate to cover the suction port (12).

[0110] In the drawing, the driving device (200) is depicted as including two springs (270a, 270b), but the present disclosure is not limited thereto. The number of springs (270) may be the same as the number of cover members described later.

[0111] 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 or off upon contact with at least one cam protrusion (233 and / or 234) of the cam (230). Based on whether the switch (280) is turned on or off, the position of the cover (100) can be determined. For example, it can be determined whether the cover (100) opens the intake port (12) or covers the intake port (12). Although the drawing illustrates two switches (280), the present disclosure is not limited thereto. The switch (280) may be provided as one or as three or more.

[0112] The cooking device (1) may include a holder (300). The holder (300) may be provided to connect the driving device (200) and the cover (100).

The holder (300) may be provided to rotate by the driving force generated by the driving device (200). The cover (100) coupled to the holder (300) may be provided to rotate together with the holder (300). As a result, the cover (100) may operate to cover or open the suction port (12).

[0113] One side of the holder (300) can be coupled to the driving device (200), and the other side of the holder (300) can be coupled to the cover (100).

[0114] The holder (300) may include a fixing member (331) that can be inserted into the first insertion hole (2161) of the frame (210). For example, the fixing member (331) can be inserted into the first insertion hole (2161) in a first direction (A, see FIGS. 8 and 9). The fixing member (331) can be inserted into the first insertion hole (2161) and connected to the guide link (260). For example, an end (3311) of the fixing member (331) can be detachably connected to a link connecting member (263) of the guide link (260).

[0115] The holder (300) may include a coupling protrusion (333). The coupling protrusion (333) of the holder (300) may be detachably coupled with a coupling groove (140) of the cover (100) to be described later. The coupling protrusion (333) may protrude from the fixing portion (331). The coupling protrusion (333) may protrude from the fixing portion (331) toward the cover (100). As will be described later, when the holder (300) includes a shield portion (332), the coupling protrusion (333) may protrude from the shield portion (332) toward the cover (100). For example, the coupling protrusion (333) may extend from the fixing portion (331) in a second direction (B1 or B2, see FIG. 8) intersecting the first direction (A). For example, in the case of the holder (300a), the coupling protrusion (333) can extend from the fixing portion (331) in a second direction (B1) intersecting the first direction (A). For example, in the case of the holder (300b), the coupling protrusion (333) can extend from the fixing portion (331) in a second direction (B2) intersecting the first direction (A).

[0116] The coupling protrusion (333) may be provided to be rotatable around the fixing portion (331) inserted into the first insertion hole (2161). The coupling protrusion (333) may be rotated approximately in an arc around the fixing portion (331) inserted into the first insertion hole (2161).

[0117] The holder (300) may include a hook (334). The hook (334) may be formed on the engaging protrusion (333). The hook (334) may protrude from an end of the engaging protrusion (333). The hook (334) of the holder (300) may be arranged to be caught in a hook groove (160) of a cover (100) to be described later. The hook (334) of the holder (300) may be arranged to be engaged with the hook groove (160) of the cover (100). While the hook (334) of the holder (300) and the hook groove (160) of the cover (100) are engaged, the cover (100) may not be easily separated from the holder (300). While the hook (334) of the holder (300) and the hook groove (160) of the cover (100) are engaged, the cover (100) may not be detached from the holder (300). While the hook (334) of the holder (300) and the hook groove (160) of the cover (100) are engaged, the cover (100) may not shake during the operation of opening or covering the suction port (12). The cover (100) may be driven stably.

[0118] The holder (300) may include a shield portion (332). The shield portion (332) may extend from the fixing portion (331). For example, the shield portion (332) may be provided between the fixing 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 holder (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.

[0119] In the drawing, the cooking appliance (1) is depicted as including two holders (300a, 300b), but the present disclosure is not limited thereto. The number of holders (300) may be the same as the number of cover members described later.

[0120] The cooking appliance (1) may include a cover (100). The cover (100) may include at least one cover member (100a and / or 100b). 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) being arranged approximately along a horizontal direction (Y direction), but the present disclosure 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 a front-back direction (X direction). For example, the cover (100) may include three or more cover members. The present disclosure may include cover members provided in various numbers, shapes, and / or arrangements. For convenience of explanation, the following description will be given of an example in which the cover (100) includes a first cover member (100a) and a second cover member (100b).

[0121] In the drawing, reference signs 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 signs 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 guide link (260a), the holder (300a), the spring (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 guide link (260b), the holder (300b), the spring (270b), the first insertion hole (2161b), the second insertion hole (2162b), etc. may be provided to correspond to the second cover member (100b).

[0122] 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.

[0123] 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.

[0124] The cover (100) can be detachably connected to the holder (300). The cover (100) can be arranged to cover the suction port (12) or open the suction port (12) by being linked to the holder (300). The cover (100) can be arranged to rotate together with the holder (300). As the holder (300) rotates by the driving device (200), the cover (100) connected to the holder (300) can also rotate.

[0125] 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).

[0126] 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 a guide link (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, the present disclosure is not limited to the above-described examples, and the cover panel (110) may have various shapes.

[0127] 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 one 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).

[0128] The cover (100) may include a coupling groove (140). The coupling groove (140) may be formed in the first cover extension (120). The coupling groove (140) of the cover (100) may be detachably coupled to the coupling protrusion (333) of the holder (300).

[0130] The joining groove (140) may include a first groove (141) that is provided to be surrounded by a first rib portion (121), a second rib portion (122), and a third rib portion (123). The joining groove (140) may include a second groove portion (142) that is provided to be open on an opposite side to the first groove portion (141). For example, the second groove portion (142) may correspond to a portion of the joining groove (140) that is not surrounded by the first rib portion (121), the second rib portion (122), and the third rib portion (123). For example, the joining groove (140) may include an approximately U-shape.

[0131] The cover (100) may include a hook groove (160). The hook groove (160) of the cover (100) may be provided so that the hook (334) of the holder (300) is caught therein. The hook groove (160) may have a shape corresponding to the hook (334). The hook groove (160) may be provided so as to communicate with the joining groove (140). For example, the hook groove (160) may be formed as the second rib portion (122) is sunken.

[0132] 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 deformable 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. A detailed description thereof will be provided later.

[0133] 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 the other side of the cover panel (110). For example, the second cover extension (130) may extend from the 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 to face the first cover extension (120).

[0134] 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).

[0135] Fig. 12 illustrates an example of a state in which the cover is in a position to cover the suction port. Fig. 13 is a cross-sectional view taken along line A-A' of Fig. 12. Fig. 14 is a cross-sectional view taken along line B-B' of Fig. 12. Fig. 15 illustrates an example of a state in which the cover is in a position to open the suction port. Fig. 16 is a cross-sectional view taken along line C-C' of Fig. 15. Fig. 17 illustrates an example of a state in which a portion of the cover illustrated in Fig. 16 is deformed.

[0136] Referring to FIGS. 12 to 17, the cover (100) is movable between a position covering the suction port (12) (first position, P1) and a position opening the suction port (12) (second position, P2). The cover (100) is rotatable between a position covering the suction port (12) (first position, P1) and a position opening the suction port (12) (second position, P2).

[0137] As described above, the cover (100) can rotate in conjunction with the holder (300). While the engaging protrusion (333) of the holder (300) and the engaging groove (140) of the cover (100) are engaged, the cover (100) can cover the suction port (12) or open the suction port (12) in conjunction with the holder (300). While the engaging protrusion (333) of the holder (300) and the engaging groove (140) of the cover (100) are engaged, the cover (100) can be arranged to rotate together with the holder (300) as the engaging protrusion (333) of the holder (300) rotates around the fixing portion (331) of the holder (330). The coupling groove (140) of the cover (100) coupled to the coupling protrusion (333) of the holder (300) may be arranged to rotate around the fixing portion (331) of the holder (300). The fixing portion (331) of the holder (300) may be arranged to form a rotation axis of the cover (100).

[0138] Referring to FIGS. 12 to 14, while the cover (100) is at a position (P1) covering the suction port (12), the cover (100) may be restricted from moving upward due to interference from the holder (300). That is, while the cover (100) is at a position (P1) covering the suction port (12), the cover (100) may not be separated from the holder (300).

[0139] For example, while the coupling protrusion (333) and the coupling groove (140) are coupled and the cover (100) is at a position (P1) where it covers the suction port (12), 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 holder (300) as the second rib portion (122) and the coupling protrusion (333) interfere with each other.

[0140] Referring to FIGS. 15 to 17, while the cover (100) is at a position (P2) for opening the suction port (12), the cover (100) can be provided to be detachable upward from the holder (300). That is, while the cover (100) is at a position (P2) for opening the suction port (12), the cover (100) can be provided in a detachable state from the holder (300).

[0141] 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 be arranged to face downward. Accordingly, when a user attempts to lift the cover (100), the cover (100) may not be interfered with by at least one rib portion (121, 122 and / or 123). That is, when the user lifts the cover (100), the engaging groove (140) of the cover (100) moves upward, and the engaging projection (333) of the holder (300) may come out of the engaging groove (140) through the second groove portion (142).

[0142] Referring to Fig. 17, when the engaging protrusion (333) and the engaging groove (140) are engaged, the engaging protrusion (333) and the engaging groove (140) can be provided to be separable as the second rib portion (122) is pressed away from the engaging protrusion (333). The second rib portion (122) can be provided to be elastically deformed by the slit portion (170). As the second rib portion (122) is elastically deformed, the size of the second groove portion (142) can increase. While the cover (100) moves upward in a state where the size of the second groove portion (142) is increased, the cover (100) may not interfere with the holder (300). The cover (100) can be easily separated from the holder (300).

[0143] Fig. 18 illustrates an example of a state in which the coupling groove of the cover is separated from the coupling protrusion of the holder. Fig. 19 illustrates an example of a state in which the insertion protrusion of the cover is separated from the frame.

[0144] Referring to FIGS. 18 and 19, an example of a cover (100) being separated from a holder (300) will be described.

[0145] While the cover (100) is in a position to open the suction port (12), the cover (100) can be separated from the holder (300). The engaging groove (140) of the cover (100) can be separated from the engaging protrusion (333) of the holder (330) (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 holder (330). 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 (1262) of the frame (120) (see FIG. 19). For example, by moving the cover (100) in the first direction (A, see FIG. 9) opposite to the fourth direction (D, see FIG. 9), the insertion protrusion (150) can be separated from the second insertion hole (1262). With the insertion protrusion (150) detached from the second insertion hole (1262), the second cover extension (130) of the cover (100) can be moved upward.

[0146] For example, the process of attaching the cover (100) to the holder (300) may be performed in the reverse order of the process described above. For example, the insertion protrusion (150) of the cover (100) may be inserted into the second insertion hole (1262), and then the attachment groove (140) of the cover (100) may be attached to the attachment protrusion (333) of the holder (300).

[0147] Typically, in related technologies, a cover may be configured to cover or open an intake port by being driven by a driving device or the like. However, detaching or removing a cover connected to a driving device from a cooking appliance may not be easy. For example, the entire cooking appliance may need to be disassembled, or the driving device and cover may need to be disassembled simultaneously. For example, the driving device and cover may be configured as a single module, and in this case, the cover alone cannot be disassembled or removed separately from the cooking appliance. This means that cleaning and / or maintenance of the cover may not be easy.

[0148] In contrast, according to the present disclosure, the cover (100) can be easily coupled to or separated from the holder (300). The cover (100) is not directly connected to the driving device (200), but can be connected to the driving device (200) through the holder (300). When the cover (100) is separated or removed 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 separately disassembled or removed 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.
