[0161] For example, the movable member (250) may include a body portion (251) and a wing portion (252) that is provided to be rotatable with respect to the body portion (251). For example, as the movable member (250) moves in a vertical direction (Z direction), the wing portion (252) may be provided to rotate with respect to the body portion (251). For example, as the movable member (250) moves downward (-Z direction), the wing portion (252) may contact the guide link (260) while rotating with respect to the body portion (251). The movable member (250) may be provided to be larger than a predetermined size in order to pressurize the guide link (260). The movable member (250) may be provided in a more compact size by including the wing portion (252) that is rotatable with respect to the body portion (251) and can pressurize the guide link (260).

[0162] For example, the movable member (250) may include a first wing portion (252a) that can contact a first guide link (260a).

[0163] For example, the movable member (250) may include a connecting projection (253) that is connectable to the second end (242) of the connecting rod (240). The connecting projection (253) may be inserted into the second rod hole (2422) of the connecting rod (240). The connecting projection (253) may move along the rail (212) of the frame (210) while being inserted into the second rod hole (2422).

[0164] For example, the movable member (250) may include an upper protrusion (254) and a lower protrusion (255) spaced apart from the upper protrusion (254). The upper protrusion (254) and the lower protrusion (255) may move along the rail (213) of the frame (210). When the upper protrusion (254) is located at the upper end of the rail (213), the movable member (250) may be restricted from moving upward. When the lower protrusion (255) is located at the lower end of the rail (213), the movable member (250) may be restricted from moving downward. The range of movement of the movable member (250) along the vertical direction (Z direction) may be determined by the upper protrusion (254) and the lower protrusion (255) of the movable member (250).

[0165] The moving member (250) may be referred to as a moving panel (250) or a moving block (250).

[0166] 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 perform linear reciprocating motion.

[0167] 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 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). Thus, the guide link (260), the holder (300), and the cover (100) can be arranged to rotate together. However, the present disclosure is not limited thereto, and for example, the guide link (260) can be directly connected to the cover (100) to rotate the cover (100).

[0169] For example, the guide link (260) may include a lever (261) provided to come into contact with the moving member (250). For example, the guide link (260) may include a link coupling portion (263) that is connectable to the holder (300). For example, the guide link (260) may include a guide protrusion (262) provided to move along at least one rail (214 and / or 215) formed in the frame (210). For example, the lever (261) and the guide protrusion (262) may protrude in opposite directions. As the moving member (250) moves downward (-Z direction), the lever (261) of the guide link (260) may be pressed by the moving member (250). The lever (261) of the guide link (260) may be provided to rotate about the link coupling portion (263) by the pressing force of the moving member (250). The lever (261) of the guide link (260) may be arranged to rotate in an approximately circular arc around the link coupling portion (263). Accordingly, as the guide link (260) rotates while being pressed by the moving member (250), the cover (100) can operate to open the suction port (12).

[0170] The driving device (200) may include a first guide link (260a) configured to rotate the first cover panel (110a) in a first direction (R1) about a first rotation axis (O1). As the moving member (250) moves downward (-Z direction), the first guide link (260a) may be pressed by the moving member (250) to rotate in the first direction (R1).

[0171] For example, the lever (261) of the first guide link (260a) may be arranged to rotate around the link coupling portion (263) of the first guide link (260a). The lever (261) of the first guide link (260a) may be arranged to rotate approximately in an arc around the link coupling portion (263) of the first guide link (260a). The guide protrusion (262) of the first guide link (260a) may be arranged to move along the rail (214).

[0172] The driving device (200) may include a second guide link (260b) configured to rotate the second cover panel (110b) in a second direction (R2) opposite to the first direction (R1) about the second rotation axis (O2). As the moving member (250) moves downward (-Z direction), the second guide link (260b) may be pressed by the moving member (250) to rotate in the second direction (R2).

[0173] For example, the lever (261) of the second guide link (260b) may be arranged to rotate around the link coupling portion (263) of the second guide link (260b). The lever (261) of the second guide link (260b) may be arranged to rotate approximately in an arc around the link coupling portion (263) of the second guide link (260b). The guide protrusion (262) of the second guide link (260b) may be arranged to move along the rail (215).

[0174] 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). The cover (100), which is connected to the guide link (260) via 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 (in the +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).

[0175] For example, the driving device (200) may include a first spring (270a) configured to elastically bias the first guide link (260a) in the second direction (R2). One end of the first spring (270a) may be fixed to a spring fixing portion (217a) of the frame (210). The other end of the first spring (270a) may be fixed to the first guide link (260a).

[0176] For example, the driving device (200) may include a second spring (270b) configured to elastically bias the second guide link (260b) in the first direction (R1). One end of the second spring (270b) may be fixed to a spring fixing portion (217b) of the frame (210). The other end of the second spring (270b) may be fixed to the second guide link (270b).

[0177] However, the present disclosure is not limited to the above. For example, one end of the first spring (270a) may be fixed to the frame (210), and the other end of the first spring (270a) may be fixed to the first holder (300a). For example, one end of the first spring (270a) may be fixed to the frame (210), and the other end of the first spring (270a) may be fixed to the first cover panel (110a). For example, one end of the second spring (270b) may be fixed to the frame (210), and the other end of the second spring (270b) may be fixed to the second holder (300b). For example, one end of the second spring (270b) may be fixed to the frame (210), and the other end of the second spring (270b) may be fixed to the second cover panel (110b). If the cover (100) can be rotated to cover the suction port (12) by the elastic restoring force of the spring (270), the arrangement of the spring (270) is not limited.

[0178] 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.

[0179] 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 transmit the driving force of the driving device (200) to the cover (100). The holder (300) may be provided to rotate by the driving force generated by the driving device (200). The holder (300) may be provided to connect the guide link (260) and the cover (100). The holder (300) may be provided to rotate by the guide link (260). 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).

[0180] The holder (300) may include a first connecting portion (310) connected to the guide link (260) and a second connecting portion (320) connected to the cover (100). The first connecting portion (310) may be inserted into the insertion hole (216) and connected to the link coupling portion (263) of the guide link (260). The second connecting portion (320) may be provided to be rotatable around the first connecting portion (310) inserted into the insertion hole (2161). The second connecting portion (320) may rotate approximately in an arc around the first connecting portion (310) inserted into the insertion hole (2161). The cover (100) may rotate around the first connecting portion (310) together with the second connecting portion (320).

[0181] The cooking device (1) may include a first holder (300a) configured to connect a first cover panel (110a) and a first guide link (260a). The first holder (300a) may transmit the rotational force of the first guide link (260a) to the first cover panel (110a). The first holder (300a) may form a first rotational axis (O1) of the first cover panel (110a).

[0182] One end of the first holder (300a) may be connected to the first guide link (260a), and the other end of the first holder (300a) may be connected to the first cover panel (110a). For example, the first connecting portion (310) of the first holder (300a) may be inserted into the insertion hole (2161a) and coupled to the first guide link (260a). For example, the first connecting portion (310) of the first holder (300a) may form a first rotational axis (O1). For example, the second connecting portion (320) of the first holder (300a) and the first cover panel (110a) connected to the second connecting portion (320) of the first holder (300a) may rotate about the first connecting portion (310) of the first holder (300a).

[0183] The cooking device (1) may include a second holder (300b) configured to connect a second cover panel (110b) and a second guide link (260b). The second holder (300b) may transmit the rotational force of the second guide link (260b) to the second cover panel (110b). The second holder (300b) may form a second rotational axis (O2) of the second cover panel (110b).

[0184] One end of the second holder (300b) may be connected to the second guide link (260b), and the other end of the second holder (300b) may be connected to the second cover panel (110b). For example, the first connecting portion (310) of the second holder (300b) may be inserted into the insertion hole (2161b) and connected to the second guide link (260b). For example, the first connecting portion (310) of the second holder (300b) may form a second rotational axis (O2). For example, the second connecting portion (320) of the second holder (300b) and the second cover panel (110b) connected to the second connecting portion (320) of the second holder (300b) may rotate about the first connecting portion (310) of the second holder (300b).

[0185] Next, with reference to FIGS. 10 to 15, an example of the operation of the cover (100) will be described. In FIGS. 10 to 15, an example is described in which the cover (100) is sequentially arranged in a first position (P1), a second position (P2), and a third position (P3) as the motor (220) rotates counterclockwise.

[0186] When the cover (100) is in the first position (P1), the cover (100) may have the suction port (12) completely open. For example, the cover (100) completely opening the suction port (12) may mean maximizing the flow rate of air flowing in through the suction port (12).

[0187] When the cover (100) is in the second position (P2), the cover (100) may completely cover the intake port (12). For example, the cover (100) completely covering the intake port (12) may mean blocking the flow of air flowing in through the intake port (12) or minimizing the flow rate of air flowing in through the intake port (12).

[0188] When the cover (100) is in the third position (P3), the cover (100) may be in a state of covering the suction port (12). However, in the example where the motor (220) rotates clockwise, when the cover (100) is provided in the third position (P3), the cover (100) may be in a state of opening the suction port (12). In addition, the cooking appliance (1) may be provided to suck air through the suction port (12) even when the cover (100) is in the third position (P3).

[0189] An example of a cover (100) moving from a first position (P1) to a second position (P2) will be described. The motor (220) can rotate counterclockwise. The cam shaft (231) of the cam (230) can rotate counterclockwise, drawing a semicircle approximately around the motor shaft (221). The cam shaft (231) of the cam (230) can rotate approximately 180 degrees from the highest point to the lowest point of the rail (211). The first end (241) of the connecting rod (240) can rotate together with the cam shaft (231). The second end (242) of the connecting rod (240) can move downward (-Z direction). The moving member (250) can move together with the second end (242) of the connecting rod (240). The moving member (250) can move downward (-Z direction). The upper protrusion (254) of the movable member (250) can move downward from the upper end of the rail (213). The lower protrusion (255) of the movable member (250) can move to be positioned at the lower end of the rail (213). As the movable member (250) moves downward (-Z direction), it can pressurize the first guide link (260a) and the second guide link (260b). One end of the first guide link (260a) can rotate in the first direction (R1) around the other end of the first guide link (260a). The guide protrusion (262) of the first guide link (260a) can move from the upper end of the rail (214) to the lower end. The first holder (300a) can rotate in the first direction (R1) in conjunction with the first guide link (260a). The first cover panel (110a) can rotate in a first direction (R1) by being linked to the first holder (300a). The first cover panel (110a) can rotate in the first direction (R1) around the first rotation axis (O1). One end of the second guide link (260b) can rotate in a second direction (R2) around the other end of the second guide link (260b).The guide protrusion (262) of the second guide link (260b) can move from the upper end to the lower end of the rail (215). The second holder (300b) can rotate in the second direction (R2) by being linked to the second guide link (260b). The second cover panel (110b) can rotate in the second direction (R2) by being linked to the second holder (300b). The second cover panel (110b) can rotate in the second direction (R2) around the second rotation axis (O2). Through the above-described process, the cover (100) can move from the first position (P1) to the second position (P2). That is, the cover (100) can be switched from a state of covering the suction port (12) to a state of opening the suction port (12).

[0190] An example of a cover (100) moving from a second position (P2) to a third position (P3) will be described. The motor (220) can rotate counterclockwise. The cam shaft (231) of the cam (230) can rotate counterclockwise, roughly drawing an arc around the motor shaft (221). FIGS. 14 and 15 illustrate an example in which the cam shaft (231) of the cam (230) rotates approximately 90 degrees at the lowest point of the rail (211). The cam shaft (231) of the cam (230) can be positioned between the lowest point and the highest point of the rail (211). The first end (241) of the connecting rod (240) can rotate together with the cam shaft (231). The second end (242) of the connecting rod (240) can move upward (in the +Z direction). The movable member (250) can move together with the second end (242) of the connecting rod (240). The movable member (250) can move upward (in the +Z direction). The lower protrusion (255) of the movable member (250) can move upward from the lower end of the rail (213). As the movable member (250) moves upward (in the +Z direction), the first guide link (260a) and the second guide link (260b) may not be pressed. The first guide link (260a) that is not pressed by the movable member (250) can rotate in the second direction (R2) as it is elastically biased by the first spring (270a). One end of the first guide link (260a) can rotate in the second direction (R2) about the other end of the first guide link (260a). The guide projection (262) of the first guide link (260a) can move from the lower end to the upper end of the rail (214). The first holder (300a) can rotate in the second direction (R2) by being linked to the first guide link (260a). The first cover panel (110a) can rotate in the second direction (R2) by being linked to the first holder (300a).The first cover panel (110a) can rotate in the second direction (R2) about the first rotation axis (O1). One end of the second guide link (260b) can rotate in the first direction (R1) about the other end of the second guide link (260b). The guide protrusion (262) of the second guide link (260b) can move from the lower end of the rail (215) toward the upper end. The second holder (300b) can rotate in the first direction (R1) by being linked to the second guide link (260b). The second cover panel (110b) can rotate in the first direction (R1) by being linked to the second holder (300b). The second cover panel (110b) can rotate in the first direction (R1) about the second rotation axis (O2). Through the above-described process, the cover (100) can move from the second position (P2) to the third position (P3). That is, the cover (100) can be switched from a state in which the suction port (12) is open to a state in which the suction port (12) is covered.

[0191] Meanwhile, the first holder (300a) may form a first rotation axis (O1), and the first guide link (260a) and the first cover panel (110a) connected to the first holder (300a) may be arranged to share the first rotation axis (O1). The second holder (300b) may form a second rotation axis (O2), and the second guide link (260b) and the second cover panel (110b) connected to the second holder (300b) may be arranged to share the second rotation axis (O2).

[0192] Fig. 16 is an enlarged view of a portion of a state in which the cover is in the first position (P1). Fig. 17 is an enlarged view of a portion of a state in which the cover is in the second position (P2). Fig. 18 is a drawing for explaining a relationship that prevents collision between the first cover panel and the second cover panel. Fig. 19 is a drawing for explaining a relationship that prevents the cover from protruding upward from the cooktop.

[0193] Referring to FIG. 16, while the cover (100) is at the first position (P1), the first cover panel (110a) and the second cover panel (110b) may be arranged in parallel along a substantially horizontal direction (Y direction). While the cover (100) is at the first position (P1), it may be arranged so that no step occurs between the first cover panel (110a) and the plate (11) within a predetermined error range. While the cover (100) is at the first position (P1), it may be arranged so that no step occurs between the second cover panel (110b) and the plate (11) within a predetermined error range. For example, while the cover (100) is at the first position (P1), the first upper portion (115a) of the first cover panel (110a) may be provided on approximately the same plane as the upper surface (11a) of the plate (11) or may be provided to be approximately parallel to the upper surface (11a) of the plate (11). For example, while the cover (100) is at the first position (P1), the second upper portion (115b) of the second cover panel (110b) may be provided on approximately the same plane as the upper surface (11a) of the plate (11) or may be provided to be approximately parallel to the upper surface (11a) of the plate (11).

[0194] Referring to FIG. 17, while the cover (100) is in the second position (P2), at least a portion of the first cover panel (110a) and at least a portion of the second cover panel (110b) may be arranged to face each other. For example, while the cover (100) is in the second position (P2), the first upper portion (115a) of the first cover panel (110a) and the second upper portion (115b) of the second cover panel (110b) may be arranged to face each other. For example, while the cover (100) is in the second position (P2), the first upper portion (115a) of the first cover panel (110a) may be arranged to face the inside of the suction port (12). For example, while the cover (100) is in the second position (P2), the second upper portion (115b) of the second cover panel (110b) may be positioned so as to face the inside of the suction port (12). For example, while the cover (100) is in the second position (P2), the first upper portion (115a) of the first cover panel (110a) and the second upper portion (115b) of the second cover panel (110b) may be positioned with the vertical center line (V) of the suction port (12) interposed therebetween.

[0195] The cover (100) may not protrude upward from the cooktop (10) while in the second position (P2). The cover (100) may not protrude upward from the plate (11) while in the second position (P2). While the cover (100) is in the second position (P2), the first cover panel (110a) and the second cover panel (110b) may not protrude upward from the upper surface (11a) of the plate (11). However, the above-described content may mean that the cover (100) does not protrude upward from the cooktop (10) within a predetermined error range.

[0196] The driving device (200) can guide the cover (100) so that it does not protrude upwards from the plate (11) while the cover (100) is in the second position (P2). While the cover (100) moves from the first position (P1) to the second position (P2), the driving device (200) can guide a portion of the cover (100) to move downwards.

[0197] For example, the driving device (200) can guide the first edge portion (111a) of the first cover panel (110a) and the first edge portion (111b) of the second cover panel (110b) to move downward while the cover (100) moves from the first position (P1) to the second position (P2). The first cover panel (110a) can rotate in the first direction (R1) around the first rotation axis (O1) by the first guide link (260a). As a result, the first edge portion (111a) of the first cover panel (110a) can move downward. The second cover panel (110b) can rotate in the second direction (R2) around the second rotation axis (O2) by the second guide link (260b). Accordingly, the first edge portion (111b) of the second cover panel (110b) can move downward.

[0198] The first rotation axis (O1) may be located further from the second cover panel (110b) than the vertical center line (C1) of the first cover panel (110a) while the cover (100) is in the first position (P1). The first rotation axis (O1) may be located below the horizontal center line (C2) of the first cover panel (110a) while the cover (100) is in the first position. When the first cover panel (110a) is rotated about the first rotation axis (O1) described above and is in a position to open the suction port (12), the first cover panel (110a) may not protrude beyond the plate (11). The second edge portion (112a) of the first cover panel (110a) may not protrude beyond the upper surface (11a) of the plate (11) within a predetermined error range.

[0199] The second rotation axis (O2) may be located further from the first cover panel (110a) than the vertical center line of the second cover panel (110b) while the cover (100) is in the second position (P2). The second rotation axis (O2) may be located below the horizontal center line of the second cover panel (110b) while the cover (100) is in the second position. When the second cover panel (110b) is rotated about the second rotation axis (O2) described above and is in a position to open the suction port (12), the second cover panel (110b) may not protrude beyond the plate (11). The second edge portion (112b) of the second cover panel (110b) may not protrude beyond the upper surface (11a) of the plate (11) within a predetermined error range.

[0200] Typically, in related technologies, the intake port is always open, or the cover may protrude above the cooktop. For example, if the cover opens the intake port, at least one edge of the cover may protrude above the cooktop plate. In such cases, the cover may interfere with a cooking vessel placed on the plate. The cover may collide with other components, such as the cooking vessel, and be damaged. Furthermore, the user may experience inconvenience in using the cooking appliance. For example, moving the cooking vessel from the top of the cooktop may be difficult. Ultimately, the usability of the cooking appliance may be reduced.

[0201] In contrast, according to the present disclosure, the cover (100) may not protrude upwards from the cooktop (10) while the suction port (12) is opened. For example, the first cover panel (110a) may not protrude upwards from the upper surface (11a) of the plate (11). For example, the second cover panel (110b) may not protrude upwards from the upper surface (11a) of the plate (11). As a result, the cover (100) may not interfere with a cooking vessel placed on the plate (11). The risk of damage to the cover (100) may be reduced. In addition, since space above the cooktop (10) is secured, the user can easily move the cooking vessel. Consequently, the usability of the cooking appliance (1) may be improved.

[0202] Meanwhile, the first cover panel (110a) and the second cover panel (110b) may be arranged so as not to interfere with each other. The first cover panel (110a) and the second cover panel (110b) may be arranged so as not to collide with each other while each is rotating. To this end, a gap (g) may be formed between the first cover panel (110a) and the second cover panel (110b) while the cover (100) is at the first position (P1).

[0203] The gap (g) may be arranged to be determined according to the position of the first rotation axis (O1) and the position of the second rotation axis (O2). The gap (g) may vary according to the position of the first rotation axis (O1) and the position of the second rotation axis (O2).

[0204] For example, the larger the width of the suction port (12), the larger the gap (g) can be. For example, the closer the first rotation axis (O1) is to the vertical center line (V) of the suction port (12), the larger the gap (g) can be. For example, the closer the second rotation axis (O2) is to the vertical center line (V) of the suction port (12), the larger the gap (g) can be. For example, the further downward the first rotation axis (O1) is from the upper surface (11a) of the plate (11), the larger the gap (g) can be. For example, the further downward the second rotation axis (O2) is from the upper surface (11a) of the plate (11), the larger the gap (g) can be.

[0205] Referring to FIG. 18, a relationship regarding the distance (L3) of the gap (g) formed between the first cover panel (110a) and the second cover panel (110b) while the cover (100) is at the first position (P1) can be derived. The first cover panel (110a) and the second cover panel (110b) can be arranged to be symmetrical with respect to the vertical center line (V) of the suction port (12). The first cover panel (110a) and the second cover panel (110b) can have substantially the same shape. Hereinafter, a relationship regarding the distance (L3) of the gap (g) is derived based on the first cover panel (110a). However, the relationship regarding the distance (L3) of the gap (g) can be derived in the same manner based on the second cover panel (110b). Therefore, the length (distance) related to the first cover panel (110a) described below can be replaced with the length (distance) related to the second cover panel (110b).

[0206] Referring to FIG. 18, (i) the distance in the horizontal direction between the first edge portion (111a) of the first cover panel (110a) and the first rotation axis (O1) may be a value obtained by adding half (W / 2) of the width (W) of the first cover panel (110a) and the shortest distance (L1) between the vertical center line (C1) of the first cover panel (110a) and the first rotation axis (O1). (ii) the distance in the vertical direction between the upper portion (115a) of the first cover panel (110a) and the first rotation axis (O1) may be a value obtained by adding the thickness (H) of the first cover panel (110a) and the shortest distance (L2) between the first cover panel (110a) and the first rotation axis (O1). (ⅲ) The distance connecting the first edge portion (111a) of the first cover panel (110a) and the first rotation axis (O1) is, by the Pythagorean theorem, It can be. The above distance( ) is less than or equal to (L3 / 2 + W / 2 + L1), which is the sum of half (L3 / 2) of the distance (L3) of the gap (g), half (W / 2) of the width (W) of the first cover panel (110a), and the shortest distance (L1) between the vertical center line (C1) of the first cover panel (110a) and the first rotation axis (O1), the first cover panel (110a) and the second cover panel (110b) may not collide. Accordingly, the distance (L3) of the gap (g) may satisfy the following relationship.

[0207] [Relationship]

[0208] W: Width of the first cover panel

[0209] H: Thickness of the first cover panel

[0210] L1: Shortest distance between the vertical center line of the first cover panel and the first rotation axis

[0211] L2: Shortest distance between the first cover panel and the first rotation axis

[0212] L3: Distance of the gap formed between the first cover panel and the second cover panel

[0213] Referring to Fig. 19, a relationship can be derived to prevent the cover (100) from protruding upwards from the plate (11) while in the second position (P2). In Fig. 19, a state in which the first cover panel (110a) rotates approximately 90 degrees to open the suction port (12) is illustrated as an example. For example, it can be assumed that the second edge portion (112a) of the first cover panel (110a) is maximally protruded from the frame (210) while the cover (100) is in the second position (P2). The first cover panel (110a) and the second cover panel (110b) can be arranged to be symmetrical with respect to the vertical center line (V) of the suction port (12). The first cover panel (110a) and the second cover panel (110b) can have substantially the same shape. Hereinafter, a relationship regarding the shortest distance (L2) between the cover panel and the rotation axis is derived based on the first cover panel (110a). However, the relationship regarding the shortest distance (L2) between the cover panel and the rotation axis can be derived in the same manner based on the second cover panel (110b). Therefore, the length (distance) related to the first cover panel (110a) described below can be replaced with the length (distance) related to the second cover panel (110b).

[0214] While the cover (100) is at the first position (P1), the vertical distance between the upper portion (115a) of the first cover panel (110a) and the first rotation axis (O1) may be H + L2. While the cover (100) is at the second position (P2), the vertical distance between the second edge portion (112a) of the first cover panel (110a) and the first rotation axis (O1) may be W / 2 - L1. In order for the cover (100) not to protrude upward from the plate (11) while it is at the second position (P2), H + L2 ≥ W / 2 - L1 must be satisfied. Accordingly, the shortest distance (L2) between the first cover panel (110a) and the first rotation axis (O1) may satisfy the following relationship.

[0215] [Relationship] L2 ≥ W / 2 - H - L1

[0216] W: Width of the first cover panel

[0217] H: Thickness of the first cover panel

[0218] L1: Shortest distance between the vertical center line of the first cover panel and the first rotation axis

[0219] L2: Shortest distance between the first cover panel and the first rotation axis

[0220] In addition, the shortest distance between the second cover panel (110b) and the second rotation axis (O2) can also satisfy the above relationship. However, in the above relationship, the distance (length) related to the first cover panel (110a) is replaced with the distance (length) related to the second cover panel (110b), and the first rotation axis (O1) is replaced with the second rotation axis (O2).

[0221] Meanwhile, each of the relationships derived in FIGS. 18 and 19 can also be applied to other embodiments (e.g., the embodiments illustrated in FIGS. 20 to 40 described below).
