[0039] The first connection unit (300) of the main body module (100) and the second connection unit (400) of the function module (200) can be designed in consideration of the upper structure of the main body module (100) and the assembly process of the main body module (100) and the function module (200).

[0040] For example, in the main body module (100), an exhaust port (102) for exhausting air may be provided in the upper central portion of the main body housing (101). In the functional module (200), a second intake port (205) into which air exhausted from the exhaust port (102) is introduced may be provided in the lower central portion of the sub-housing (201). The second connection unit (400) of the functional module (200) and the first connection unit (300) of the main body module (100) may be arranged so as not to interfere with the air movement path.

[0041] For example, the first connection unit (300) of the main body module (100) may be disposed at a periphery portion of the end facing the function module (200). The first connection unit (300) may be disposed around the discharge port (102) at the top of the main body module (100). The second connection unit (400) of the function module (200) may be disposed at a periphery portion of the end facing the main body module (100) of the function module (200). The second connection unit (400) may be disposed around the second suction port (205) at the top of the function module (200).

[0042] The output terminal (150) of the main body module (100) may be arranged in the first connection unit (300). The output terminal (150) may be arranged on the edge portion of the end of the main body module (100) facing the function module (200). The connection terminal (220) of the function module (200) may be arranged in the second connection unit (400). The connection terminal (220) may be arranged on the edge portion of the end of the function module (200) facing the main body module (100).

[0043] FIG. 7 is a diagram showing an example of the first and second connection units (300, 400) of the air purifier (1) of FIG. 6 according to various embodiments. FIG. 8 is a diagram showing a part of the first and second connection units (300, 400) of FIG. 7 according to various embodiments in isolation. FIG. 9a is a diagram showing the first connection unit (300) of FIG. 8 in isolation according to various embodiments, and FIG. 9b is a diagram showing the second connection unit (400) of FIG. 8 in isolation according to various embodiments. FIGS. 10 and 11 are cross-sectional views for explaining the operation of the first and second connection units (300, 400) of FIGS. 8 to 9b according to various embodiments.

[0044] Referring to FIGS. 6 to 11, the first connection unit (300) and the second connection unit (400) according to the embodiment may be configured to be assembled without rotational movement of the function module (200). For example, the first connection unit (300) and the second connection unit (400) may be configured to be fixed to each other by at least one of the vertical movement of the second connection unit (400) and the horizontal movement of the second connection unit (400). For example, the first connection unit (300) and the second connection unit (400) may be configured to be detachably fixed to each other by at least one of a push latch method and a lever lock method.

[0045] For example, the first connection unit (300) and the second connection unit (400) can be configured to be fixed (or connected) to each other through the vertical movement of the second connection unit (400) and the movement of the lever member (410) of the second connection unit (400). By fixing the first connection unit (300) and the second connection unit (400), the function module (200) and the main body module (100) can be electrically connected.

[0046] For example, the first connection unit (300) of the main body module (100) includes a base member (310) and an elevating member (320) that can move up and down with respect to the base member (310). A hook member (321) is arranged at the lower portion of the elevating member (320), and the base member (310) includes a hook engaging member (311) configured to fix the hook member (321) by a push latch method when the elevating member (320) is lowered. By the push latch method, the hook engaging member (311) can be released from fixation to the hook member (321) when the elevating member (320) is lowered again.

[0047] The lifting member (320) may be elastically pressed in an upward direction. An elastic member (330) (e.g., a spring) for elastically pressing the lifting member (320) upward may be included between the lifting member (320) and the base member (310). An output terminal (150) for electrical connection with the function module (200) may be arranged on the edge of the lifting member (320).

[0048] The second connection unit (400) of the function module (200) may include a lever member (410) and a locking member (420) that is movable in the radial and centrifugal directions in conjunction with the lever member (410). The second connection unit (400) further includes a direction changing member (430) for changing the rotational movement of the lever member (410) into the centrifugal movement of the locking member (420).

[0049] The direction changing member (430) may include a rotating member (431) that is fixed to the lever member (410) and rotates together with the lever member (410), and a guide member (432) that guides the centrifugal movement of the locking member (420). The locking member (420) may be fixed by a support member (433) that penetrates the rotating member (431) and the guide member (432).

[0050] The locking member (420) can move radially or centrifugally in conjunction with the operation of the lever member (410). When the lever member (410) rotates, the locking member (420) can move centrifugally or radially in a direction opposite to the centrifugal direction by the direction changing member (430) depending on the rotational direction. A connection terminal (220) for electrical connection with the main body module (100) can be arranged on the locking member (420).

[0051] The locking member (420) may have a contact position (421) that surrounds and contacts the edge of the lifting member (320) of the first connecting unit (300), and a non-contact position (421) that is spaced apart from the contact position in a radial direction so as not to contact the edge of the lifting member (320).

[0052] When the second connection unit (400) is placed on the first connection unit (300) and the second connection unit (400) is pressed downward, as shown in Fig. 10, the hook member (321) of the first connection unit (300) can be fixed to the hook engagement member (311) of the base member (310). At this time, the locking member (420) can be in a non-contact position (422) that does not come into contact with the edge of the lifting member (320).

[0053] By rotating the lever member (410) while the hook member (321) is fixed to the hook coupling member (311), the locking member (420) can be moved to the contact position (421), as shown in Fig. 11. For example, a user can rotate the lever member (410) in the first direction to move the locking member (420) to the contact position. In the process of moving the locking member (420) to the contact position (421), the connection terminal (220) can be electrically connected to the output terminal (150).

[0054] As described above, by pressing the second connection unit (400) downward and rotating the lever member (410), the function module (200) and the main body module (100) can be structurally assembled and electrically connected. The structural separation and electrical separation of the function module (200) and the main body module (100) can be performed in the opposite manner to the above-described method. For example, by rotating the lever member (410) in the opposite direction and re-pressuring the second connection unit (400) downward, the function module (200) and the main body module (100) can be structurally separated and electrically separated.

[0055] In the above-described embodiment, the assembly method of the first connection unit (300) and the second connection unit (400) has been described with a focus on examples using the lever lock method and the push latch method. However, the assembly method of the first connection unit (300) and the second connection unit (400) is not limited thereto and may vary.

[0056] FIG. 12 is a drawing showing an example of the first and second connection units (300A, 400A) of the air purifying device (1) of FIG. 6 according to various embodiments. FIG. 13 is an exploded perspective view showing an example of the first and second connection units (300A, 400A) of the air purifying device (1) of FIG. 12 according to various embodiments. FIG. 14 is a cross-sectional view for explaining the operation of the first and second connection units (300A, 400A) of FIG. 12 according to various embodiments.

[0057] Referring to FIGS. 12 to 14, the first connection unit (300A) and the second connection unit (400A) can be configured to be assembled by vertical movement. The first connection unit (300A) includes an elevating member (320a) and a base member (310a) provided to fix or release the position of the elevating member (320a) in the vertical direction. The first connection unit (300A) includes a cover member (350) to prevent / suppress the elevating member (320a) from being detached.

[0058] The lifting member (320a) may include a first connecting portion (323) for assembly with a second connecting unit (400A). The second connecting unit (400A) may include a second connecting portion (450) for coupling to the first connecting portion (323).

[0059] The first coupling portion (323) and the second coupling portion (450) may be configured to be fitted together. For example, the shape of the outer circumference of the first coupling portion (323) may correspond to the shape of the inner circumference of the second coupling portion (450). The outer diameter of the first coupling portion (323) and the inner diameter of the second coupling portion (450) may correspond. For example, the outer diameter of the first coupling portion (323) may be the same as or slightly larger than the inner diameter of the second coupling portion (450). Here, the slightly larger size may refer to a size at which the first coupling portion (323) is inserted into the interior of the second coupling portion (450) by deformation without damage to the first coupling portion (323) or the second coupling portion (450).

[0060] In the process of moving the function module (200) up and down relative to the main body module (100), the second coupling part (450) can be fitted into the first coupling part (323). In this state, the second coupling part (450) can press the first coupling part (323) up and down.

[0061] The base member (310a) includes a receiving portion defining a receiving space for receiving a portion of the elevating member (320a) when the elevating member (320a) is lowered. The inner surface of the receiving portion includes a plurality of guide grooves (312) for guiding the elevation of the elevating member (320a) when the elevating member (320a) is raised and a stopper (3123) for restricting the vertical movement of the elevating member (320a). The plurality of guide grooves (312) may extend in the vertical direction.

[0062] The lifting member (320a) includes a vertical moving member (325) that moves up and down along the base member (310a), and a rotation inducing member (324) that induces rotation of the vertical moving member (325).

[0063] The outer surface of the vertical moving member (325) may include a plurality of guide protrusions (326a) that move along the guide groove (312). The plurality of guide protrusions (326a) include first and second guide protrusions (3261, 3262) that have different protrusion heights in the radial direction. The protrusion height of the first guide protrusion (3261) is higher than that of the second guide protrusion (3262). The first guide protrusion (3261) and the second guide protrusion (3262) may be alternately arranged on the outer surface of the lifting member (320a).

[0064] The plurality of guide grooves (312) may include a first guide groove (3121) that guides the up-and-down movement of the first guide protrusion (3261) and a second guide groove (3122) that guides the up-and-down movement of the second guide protrusion (3262). A stopper (3123) of the base member (310a) may limit the up-and-down movement of the first guide protrusion (3261) and allow the up-and-down movement of the second guide protrusion (3262). For example, the stopper (3123) may be provided in the second guide groove (3122).

[0065] The rotation induction part (324) may be arranged on the upper part of the vertical movement part (325). The edge of the rotation induction part (324) includes at least one rotation induction protrusion (3241). The rotation induction protrusion (3241) may be arranged on the upper part of the guide protrusion (326a). An inclined surface that induces rotation of the guide protrusion (326a) may be arranged on the lower part of the rotation induction protrusion (3241).

[0066] When the lifting member (320a) descends, the first guide protrusion (3261) descends along the first guide groove (3121), and the second guide protrusion (3262) descends along the second guide groove (3122). When the guide protrusion (326a) of the vertical moving unit (325) descends out of the guide groove (312), the vertical moving unit (325) is in a state where it can rotate in the circumferential direction. The guide protrusion (326a) of the vertical moving unit (325) is pressed by the rotation induction protrusion (3241) of the rotation induction unit (324), and can rotate. The guide protrusion (326a) can be rotated so that the first guide protrusion (3261) can be positioned at the bottom of the second guide groove (3122), and the second guide protrusion (3262) can be positioned at the bottom of the first guide groove (3121).

[0067] Even if an elastic force is applied in the upward direction by the elastic member (330), the movement of the first guide protrusion (3261) in the upward direction is restricted by the stopper (3123) of the second guide groove (3122). Thus, the lifting member (320a) can be fixed in position in the vertical direction while inserted into the base member (310a).

[0068] When force is applied again in the up-and-down direction to the lifting member (320a), the guide protrusion (326a) of the up-and-down moving member (325) can be additionally rotated by the rotation induction member (324). The first guide protrusion (3261) can be positioned at the bottom of the first guide groove (3121), and the second guide protrusion (3262) can be positioned at the bottom of the second guide groove (3122). Since the lifting member (320a) is subjected to an upward elastic force by the elastic member (330), the first guide protrusion (3261) rises along the first guide groove (3121), and the second guide protrusion (3262) rises along the second guide groove (3122). Thus, the lifting member (320a) moves upward.

[0069] The structure for raising and lowering the above-described lifting member (320a) is an example of a structure for a push latch method, and is not necessarily limited thereto, and can be modified in various ways as long as the structure is for assembly in the up-down direction.

[0070] FIG. 15 is a drawing showing an example of the first and second connection units (300B, 400A) of the air purifying device (1) of FIG. 6 according to various embodiments. FIG. 16 is an exploded perspective view showing an example of the first and second connection units (300B, 400A) of the air purifying device (1) of FIG. 15 according to various embodiments. FIG. 17 is a drawing for explaining an exemplary operation of the first and second connection units (300B, 400A) of FIG. 15 according to various embodiments.

[0071] For example, referring to FIGS. 15 to 17, the first connection unit (300B) and the second connection unit (400A) can be configured to be assembled by vertical movement. The first connection unit (300B) includes an elevating member (320b) and a base member (310b) provided to fix or release the position of the elevating member (320b) in the vertical direction. The first connection unit (300B) includes a cover member (350) to prevent / block the elevating member (320b) from coming off.

[0072] The first coupling portion (323) and the second coupling portion (450) may be configured to be fitted together. For example, the shape of the outer circumference of the first coupling portion (323) may correspond to the shape of the inner circumference of the second coupling portion (450). The outer diameter of the first coupling portion (323) and the inner diameter of the second coupling portion (450) may correspond. For example, the outer diameter of the first coupling portion (323) may be the same as or slightly larger than the inner diameter of the second coupling portion (450). Here, the slightly larger size may refer to a size at which the first coupling portion (323) is inserted into the interior of the second coupling portion (450) by deformation without damage to the first coupling portion (323) or the second coupling portion (450).

[0073] In the process of moving the function module (200) up and down relative to the main body module (100), the second coupling part (450) can be fitted into the first coupling part (323). In this state, the second coupling part (450) can press the first coupling part (323) up and down.

[0074] The base member (310b) includes a receiving portion that defines a receiving space for receiving a portion of the elevating member (320b) when the elevating member (320b) is lowered. On the inner surface of the receiving portion, a plurality of guide rails (313) are included that guide the elevation and rotation of the elevating member (320) when the elevating member (320b) is raised and lowered. The plurality of guide rails (313) may extend so as to be inclined in the up-down direction. A stopper (not shown) may be provided at an end of the guide rail (313) to maintain the position of the guide protrusion (326b).

[0075] The lifting member (320b) is inserted into the guide rail (313) and may include a guide protrusion (326b) that moves along the guide rail (313). When the lifting member (320b) descends, the guide protrusion (326b) moves along the guide rail (313), and the lifting member (320b) descends while rotating counterclockwise. When the lifting member (320b) rises, the guide protrusion (326b) moves along the guide rail (313), and the lifting member (320b) rises while rotating clockwise.

[0076] FIG. 18 is a drawing showing an example of the first and second connection units (300C, 400C) of the air purifier (1) of FIG. 6 according to various embodiments. FIG. 19 is a drawing for explaining the operation of the first and second connection units (300C, 400C) of FIG. 18 according to various embodiments.

[0077] Referring to FIGS. 18 and 19, the first and second connection units (300C, 400C) according to the embodiment can be assembled by horizontal movement. For example, with the function module (200) placed on top of the main body module (100), the function module (200) can be moved horizontally and fixed to the main body module (100).

[0078] For example, the first connecting unit (300C) may include a protruding portion (340) protruding upward. The edge of the protruding portion (340) may include a locking protrusion (341) protruding horizontally.

[0079] The second connection unit (400C) may include a locking groove (440) that accommodates the first connection unit (300C). The locking groove (440) includes a first receiving portion (441) that accommodates a protruding portion (340) and a locking projection (341), and a second receiving portion (442) that is connected to the first receiving portion (441) and has a smaller size than the first receiving portion (441) to correspond to the protruding portion (340). After the function module (200) is positioned on the main body module (100) so that the first connection unit (300C) is inserted into the first receiving portion (441), the function module (200) may be moved horizontally as a whole to position the first connection unit (300C) in the second receiving portion (442). The second receiving portion (442) can limit the vertical movement of the first connecting unit (300C) and the second connecting unit (400C) by limiting the vertical movement of the locking protrusion (341).

[0080] Although not shown, the first connection unit (300A, 300B, 300C) may be provided with an output terminal (150), and the second connection unit (400A, 400C) may be provided with a connection terminal (220). During the horizontal or vertical movement of the first connection unit (300) and the second connection unit (400), the output terminal (150) and the connection terminal (220) may be electrically connected. In this way, during the vertical or horizontal movement of the function module (200), the function module (200) and the main body module (100) may be electrically connected and structurally connected at the same time.

[0082] Referring to FIGS. 20 to 22, the output terminals (150a, 150b, 150c) and the connection terminals (220a, 220b, 220c) for electrical connection can be configured to be connected by moving in the up-and-down direction or moving in the horizontal direction.

[0083] For example, either the output terminal (150a, 150b, 150c) or the connection terminal (220a, 220b, 220c) may have a protruding structure. For example, either the connection terminal (220a, 220b, 220c) may have a protruding structure. For example, either the output terminal (150a, 150b, 150c) or the connection terminal (220a, 220b, 220c) may have a protruding structure. For example, as shown in FIG. 20, the output terminal (150a) may have a concave structure, and the connection terminal (220a, 220b, 220c) may have a protruding structure configured to be insertable into the concave structure. At least one of the output terminal (150a) and the connection terminal (220a) can move in the vertical direction so that the output terminal (150a) and the connection terminal (220a) can be connected to each other.

[0084] At least one of the output terminal (150b) and the connection terminal (220b) may have a structure that is elastically deformable in the vertical direction for connection stability. For example, at least one of the output terminal (150b) and the connection terminal (220b) may further include an elastic member (221) (e.g., a spring) that provides elastic force in the vertical direction. For example, the elastic member (221) may be arranged in a protruding structure. For example, as shown in FIG. 21, the elastic member (221) may be arranged inside the connection terminal (220b). Depending on the elasticity of the elastic member (221), the protruding length of the connection terminal (220b) may change. However, the arrangement of the elastic member (221) is not limited thereto and may vary. For example, although not illustrated, the elastic member (221) may be arranged in a concave structure. The output terminal (150b) may have a flat structure that can come into contact with the connection terminal (220b).

[0085] However, the structures of the output terminals (150a, 150b, 150c) and the connection terminals (220a, 220b, 220c) are not limited thereto and may vary. For example, although not illustrated, the output terminals (150a, 150b, 150c) may have a protruding structure, and the connection terminals (220a, 220b, 220c) may have a concave structure configured such that the protruding structure can be inserted.

[0086] The connection method of the output terminals (150a, 150b, 150c) and the connection terminals (220a, 220b, 220c) may be various in addition to the vertical direction. For example, at least one of the output terminals (150a, 150b, 150c) and the connection terminals (220a, 220b, 220c) may move horizontally and be electrically connected. For example, as shown in FIG. 22, the output terminal (150c) and the connection terminal (220c) may be electrically connected in the process of the connection terminal (220c) moving horizontally.

[0087] The main body module (100) and the function module (200) can be configured to operate in an assembled state as well as in a separated state. The function module (200) can be configured to operate in a separated state from the main body module (100).

[0088] FIG. 23 is a drawing for explaining an exemplary operation of the air purifying device (1) when the main body module (100) and the function module (200) according to various embodiments are separated, and FIG. 24 is a drawing for explaining the operation of the air purifying device (1) when the function module (200) according to various embodiments is assembled to the main body module (100). FIG. 25a is a drawing for explaining an example of use when the main body module (100) and the function module (200, 200A) according to various embodiments are assembled, and FIG. 25b is a drawing for explaining an example of use when the main body module (100) and the function module (200, 200A) according to various embodiments are separated. FIG. 26 is a block diagram showing an exemplary configuration of the main body module (100) and the function module (200) of the air purifying device (1) according to various embodiments.

[0089] Referring to FIGS. 23 and 24, the air purifying device (1) according to the embodiment can be configured to be operable in a state where the function module (200) is assembled to the main body module (100) and in a state where it is separated from the main body module (100).

[0090] For example, the function module (200) may include a second power supply unit (230) configured to receive power separate from the power supplied to the power supply unit (140) of the main body module (100). The function module (200) may operate through power received through the second power supply unit (230) even when it is separated from the main body module (100).

[0091] The second power supply unit (230) may include a power adapter (232) configured to supply power to the function module (200). For example, the second power supply unit (230) may include a power adapter (232) detachably provided on the function module (200) and an input terminal (231) configured to be electrically connected to the power adapter (232). The second power supply unit (230) may be configured to receive alternating current (AC) power. The power adapter (232) may be configured to receive alternating current (AC) power. However, the power supplied to the second power supply unit (230) is not necessarily limited to alternating current power and may be direct current power.

[0092] The second power supply unit (230) of the function module (200) may further include a battery (not shown). The battery may be a rechargeable secondary battery. However, since the battery is an optional component of the function module (200), it may be omitted as needed. The second power supply unit (230) may also include a battery instead of a power adapter (232).

[0093] The function module (200) may include a switch (240) configured to selectively receive power from either the connection terminal (220) or the second power supply (230).

[0094] The switch (240) can change the path of power supplied to the function unit (210) depending on whether the second power supply unit (230) is connected to the function module (200). For example, the switch (240) can change the path of power supplied to the function unit (210) depending on whether the power adapter (232) of the second power supply unit (230) is mounted on the function module (200).

[0095] The switch (240) can be operated by the force of mounting the power adapter (232) of the second power supply unit (230). For example, the switch (240) can be pressed by the force of mounting the power adapter (232) to the input terminal (231), thereby electrically connecting the function unit (210) and the second power supply unit (230). The switch (240) can be a switch (240) operated by an external force. For example, the switch (240) can be a micro switch (240), but is not limited thereto, and can be modified in various ways as long as it can be operated by an external force.

[0096] When the power adapter (232) of the function module (200) is assembled to the input terminal (231), the switch (240) can electrically connect the function unit (210) and the power adapter (232). When the power adapter (232) of the function module (200) is separated from the input terminal (231), the switch (240) can disconnect the electrical connection between the function unit (210) and the power adapter (232).

[0097] The switch (240) can change the path of power supplied to the function unit (210) or the auxiliary control unit (260) depending on whether the connection terminal (220) of the function module (200) is assembled to the output terminal (150) of the main body module (100). The power supplied to the auxiliary control unit (260) is transmitted to the function unit (210).

[0098] For example, when the connection terminal (220) of the function module (200) is assembled to the output terminal (150) of the main body module (100), the switch (240) can electrically connect the auxiliary control unit (260) and the connection terminal (220). For example, when the connection terminal (220) of the function module (200) is separated from the output terminal (150) of the main body module (100), the switch (240) can disconnect the electrical connection between the auxiliary control unit (260) and the connection terminal (220).

[0099] The function module (200) may further include a DC power supply (245) positioned between the auxiliary control unit (260) and the switch (240). The DC power supply (245) may convert AC power into DC power. The DC power supply (245) may be a switching mode power supply (SMPS). However, the type of the DC power supply (245) is not limited thereto and may vary.

[0100] The main body module (100) may further include a module detection sensor (180) that detects the function module (200). The module detection sensor (180) may be configured to identify whether the function module (200) is assembled to the main body module (100). For example, the module detection sensor (180) may detect whether the function module (200) is assembled or approached. As an example, the module detection sensor (180) may be a magnet sensor. The main control unit (130) may detect a magnet mounted on the function module (200) through the module detection sensor (180) to determine whether the function module (200) is assembled to or approached the main body module (100).

[0101] The main control unit (130) of the main body module (100) can control the operation of the main body module (100) based on information detected by the module detection sensor (180). For example, the main control unit (130) can selectively supply power to the output terminal (150) based on information detected by the module detection sensor (180).

[0102] For example, the main control unit (130) can electrically connect or disconnect between the output terminal (150) and the power supply unit (140) based on information detected by the module detection sensor (180). As an example for this, the main body module (100) may further include a main body switch (131) disposed between the output terminal (150) and the power supply unit (140). The main body module (100) may further include a DC power supply device (135) disposed between the main control unit (130) and the power supply unit (140). The main body switch (131) may be a relay switch, but is not necessarily limited thereto and may vary.

[0103] The main control unit (130) can selectively connect the output terminal (150) and the power supply unit (140) by controlling the on / off of the main body switch (131) based on information detected by the module detection sensor (180). For example, when the module detection sensor (180) determines that the function module (200) and the main body module (100) are assembled, the main control unit (130) can control the main body switch (131) so that the output terminal (150) and the power supply unit (140) are electrically connected. When the module detection sensor (180) determines that the function module (200) and the main body module (100) are separated, the main control unit (130) can control the main body switch (131) so that the electrical connection between the output terminal (150) and the power supply unit (140) is released. The main body module (100) can prevent / suppress the current supplied through the power adapter (232) from flowing to the output terminal (150) through the main body switch (131) when the function module (200) is not assembled.

[0104] For example, the main control unit (130) can control the operation of the main body module (100) based on information detected by the module detection sensor (180). For example, when the module detection sensor (180) determines that the function module (200) is assembled to the main body module (100), the main control unit (130) can control the operating speed of the main body module (100).

[0105] Referring to FIGS. 2, 25A, and 26, the functional module (200, 200A) of the air purifier (1) may be a blower module. The functional unit (210) may be assembled to the main body module (100). In the process of assembling the functional module (200) to the main body module (100), the connection terminal (220) of the functional module (200, 200A) and the output terminal (150) of the main body module (100) may be electrically connected. By the force of assembling the functional module (200) to the main body module (100), the switch (240) may release the connection between the auxiliary control unit (260) and the second power supply unit (230), and connect the connection terminal (220) and the auxiliary control unit (260). The function module (200) can operate in conjunction with the main body module (100) through power supplied through the connection terminal (220).

[0106] The module detection sensor (180) of the main body module (100) can detect whether the function unit (210) is assembled. The main control unit (130) can control the operation of the air purifier (1) based on the information detected by the module detection sensor (180).

[0107] Depending on the operating mode set in the air purifier (1), the main control unit (130) can control the functional unit (210) of the functional module (200). For example, if the operating mode of the air purifier (1) is a mode that requires rapid diffusion of clean air indoors, the main control unit (130) can control the operation of the functional module (200) to induce rapid diffusion of clean air. For example, as shown in FIG. 4, if the functional unit (210) includes a fan and a blade (203), the main control unit (130) can adjust the rotation speed of the fan and the rotation angle of the blade (203) to quickly discharge clean air at various angles.

[0108] Referring to FIGS. 2, 25b, and 26, the air purifier (1) can operate with the function module (200) and the main body module (100) spaced apart from each other. The function module (200) can operate in conjunction with the main body module (100). As an example for this, the function module (200) can further include a communication unit (250) for communicating with an external device.

[0109] The communication unit (250) of the function module (200) can receive a signal applied from the main body module (100). For example, the auxiliary control unit (260) can receive a user command from the main body module (100) through the communication unit (160). The communication unit (250) can communicate with an external device through a wireless communication method such as BT (Bluetooth), BLE (Bluetooth Low Energy), WI-FI (Wireless Fidelity), etc.

[0110] For example, when the function module (200) is separated from the main body module (100), the function module (200, 200A) can receive power through the second power supply unit (230) and operate in conjunction with the main body module (100). For example, when the function module (200, 200A) is separated from the main body module (100), a signal can be transmitted between the main body module (100) and the function module (200, 200A) by wireless communication.

[0111] For example, when the function module (200) is a blower module, the main control unit (130) can control the operation of the function module (200, 200A). For example, as shown in FIG. 25b, when the main body module (100) and the function module (200) are spaced apart in an indoor space, the main control unit (130) can control the blowing direction of the main body module (100) and the blowing direction of the function module (200) to be different. For example, the main control unit (130) can control the blowing direction of the main body module (100) and the blowing direction of the function module (200) to face each other, or can control the blowing direction of the main body module (100) and the blowing direction of the function module (200) to be different to induce air circulation indoors.

[0112] In various embodiments, the description focuses on an example in which the functional module (200A) is a blower module that functions as a booster fan. However, the function and structure of the functional module (200A) are not limited thereto and may vary.

[0113] For example, the functional module (200, 200A) may include at least one of a blowing module having the above-described blowing function, a humidifying module performing a humidifying function, and a charging module performing a charging function. The functional module (200, 200A, 200B, 200C) may be at least one of a blowing module having the above-described blowing function, a humidifying module performing a humidifying function, and a charging module performing a charging function.

[0114] Fig. 27 is a drawing showing an example in which the functional module (200B) of the air purifier (1) according to various embodiments is a humidifying module. Fig. 28 is a drawing for explaining an example of the configuration of the functional module (200B) of Fig. 27 according to various embodiments.

[0115] Referring to FIGS. 27 and 28, an air purifier (1) according to an embodiment may include a main body module (100) and a functional module (200B). The functional module (200B) may be a humidifying module having a humidifying function.

[0116] For example, the function module (200B) may include a steam generation unit (210a) (e.g., including a circuit) for generating steam and an auxiliary control unit (260) (e.g., including a circuit) for controlling the steam generation unit (210a).

[0117] The steam generating unit (210a) may be configured to generate steam. For example, the steam generating unit (210a) may be a heater for generating steam by heating. As another example, the steam generating unit (210a) may be an ultrasonic vibrator for generating steam by ultrasonic means. As yet another example, the steam generating unit (210a) may be a fan for generating steam by vaporization. The auxiliary control unit (260) may control the operation of the steam generating unit (210a).

[0118] The function module (200B) may further include a sensor unit (281) for detecting humidity (e.g., including at least one sensor). The sensor unit (281) may detect humidity. The sensor unit (281) may detect at least one of temperature and humidity. For example, the sensor unit (281) may detect both temperature and humidity. The auxiliary control unit (260) may control the operation of the steam generation unit (210a) based on the temperature and humidity detected by the sensor unit (281).

[0119] The auxiliary control unit (260) controls the operation of the steam generation unit (210a) based on at least one of temperature and humidity detected through the sensor unit (281), and may include various circuits. The auxiliary control unit (260) can increase the amount of humidification by the steam generation unit (210a) when the humidity of the surrounding air is lower than the reference humidity. The auxiliary control unit (260) can decrease the amount of humidification by the steam generation unit (210a) when the humidity of the surrounding air is higher than the reference humidity.

[0120] The function module (200B) and the main body module (100) can operate in conjunction with each other. For example, when the sensor unit (281) of the function module (200B) detects information related to at least one of temperature and humidity, and the sensor unit (170) of the main body module (100) detects information related to the pollution level of the surrounding air, the main control unit (130) can control the blower unit (120) of the main body module (100) and the steam generating unit (210a) of the function module (200B) based on the information detected through the sensor units (170, 281) of the main body module (100) and the function module (200B), respectively. Through this, the air purifier (1) can perform an efficient purification function and a humidification function.

[0121] For example, when it is determined by the sensor unit (170) of the main body module (100) and the sensor unit (281) of the function module (200B) that the cleanliness of the surrounding air is in a bad state that does not satisfy the standard concentration and that the humidity is in an appropriate state that satisfies the standard humidity, the main control unit (130) can operate the blower unit (120) of the main body module (100) to rotate at high speed (or increase the rotation speed) and to minimize / reduce the amount of humidification by the water vapor generation unit (210a) of the function module (200B).

[0122] For example, if the sensor unit (170) of the main body module (100) and the sensor unit (281) of the function module (200B) determine that the cleanliness of the surrounding air is good enough to satisfy the standard concentration, but the humidity is low enough to not satisfy the standard humidity, the main control unit (130) can rotate the blower unit (120) of the main body module (100) at high speed for a certain period of time to quickly humidify and maintain the amount of humidification by the vapor generation unit (210a) of the function module (200B) at a high level. If the sensor unit (281) of the function module (200B) determines that the surrounding air has reached an appropriate humidity, the rotation speed of the blower unit (120) of the main body module (100) can be reduced. In this way, by simultaneously controlling the function module (200B) and the main body module (100), the humidity of the surrounding air can be quickly increased.

[0123] The function module (200B) may further include an input / output unit (270) (e.g., including an input / output circuit). The input / output unit (270) may include an input interface for receiving user commands. For example, the input interface may include a plurality of buttons for receiving user commands. The input / output unit (270) may include a display for displaying various screens related to the operation of the humidifying module or air purifying device (1). For example, the display may be implemented as various displays such as an LCD (Liquid Crystal Display), an OLED (Organic Light Emitting Diodes), etc. However, the input / output unit (270) may be an optional configuration and may be omitted from the function module (200B).

[0124] The function module (200B) may further include a communication unit (250). The communication unit (250) may receive a signal applied from the main body module (100). The main control unit (130) may transmit various data to an external device through the communication unit (160) and receive various data from the external device. For example, the auxiliary control unit (260) may receive a user command from the main body module (100) through the communication unit (250). The communication unit (250) may communicate with an external device through a wireless communication method such as BT (Bluetooth), BLE (Bluetooth Low Energy), WI-FI (Wireless Fidelity), etc. The function module (200B) and the main body module (100) may operate in conjunction with each other through the communication units (160, 250) while being spaced apart from each other.

[0125] Fig. 29 is a drawing showing an example in which the functional module (200C) of the air purifier (1) according to various embodiments is a charging module. Fig. 30 is a drawing for explaining an example of the configuration of the functional module (200C) of Fig. 29 according to various embodiments.

[0126] Referring to FIGS. 29 and 30, an air purifier (1) according to an embodiment may include a main body module (100) and a function module (200C). The function module (200C) may be a charging module having a charging function.

[0127] The function module (200C) may include at least one charging unit (210b) (e.g., including a charging circuit) and an auxiliary control unit (260) (e.g., including a circuit) that controls the charging unit (210b).

[0128] The charging unit (210b) may include a wireless charging unit capable of wirelessly charging an external device. The charging unit (210b) may further include a wired charging unit capable of charging an external device by connecting to the external device via a connection terminal.

[0129] The function module (200C) may include a charge detection unit (282) (e.g., including a detection circuit) that detects the charging state of the battery by the charging unit (210b). The charge detection unit (282) may detect whether charging of the battery is complete. If the charge detection unit (282) detects that charging of the battery is complete, the auxiliary control unit (260) may stop the operation of the charging unit (210b). The charge detection unit (282) may detect whether the battery is being charged by the charging unit (210b). For example, the charge detection unit (282) may detect whether the battery of the external device is out of the chargeable range of the charging unit (210b). In other words, the charge detection unit (282) may detect whether a charging error occurs in which the battery of the external device is placed on the charging unit (210b) but charging does not proceed.

[0130] The function module (200C) can operate in conjunction with the main body module (100). For example, the function module (200C) can be assembled into the main body module (100) and operate in conjunction with the main body module (100). For example, the main control unit (130) of the main body module (100) can provide the operating status of the function module (200C) to the user through the input / output unit (190) of the main body module (100).

[0131] For example, when charging is completed in the function module (200C), the main control unit (130) of the main body module (100) can guide the user that charging is completed through the output interface of the main body module (100). For example, the main control unit (130) can visually guide the user of the charging completion status of the external device on the function module (200C) through the display of the main body module (100). For example, the main control unit (130) can visually and audibly guide the user of the charging completion status of the external device on the function module (200C) through the display and speaker of the main body module (100).

[0132] For example, if a charging error occurs in the function module (200C) where charging is not performed on an external device, the output interface of the main body module (100) may notify the user that the charging status needs to be confirmed. For example, the display of the main body module (100) may visually notify the user that the charging status needs to be confirmed. For example, the display and speaker of the main body module (100) may visually and audibly notify the user that the charging status needs to be confirmed.

[0133] The functional module (200C) may further include a lighting unit (290) (e.g., including a light source). The lighting unit (290) may include a light source that radiates light around the functional module (200C). However, since the lighting unit (290) is an optional component of the functional module (200C), it may be omitted as needed.

[0134] The function module (200C) may further include a communication unit (250) (e.g., including a communication circuit). The communication unit (250) may receive a signal applied from the main body module (100). The communication unit (250) is a component that performs communication with an external device. The main control unit (130) may transmit various data to the external device through the communication unit (160) and receive various data from the external device. The auxiliary control unit (260) may receive a user command from the main body module (100) through the communication unit (250). The communication unit (250) may perform communication with the external device through a wireless communication method such as BT (Bluetooth), BLE (Bluetooth Low Energy), WI-FI (Wireless Fidelity), etc. The function module (200C) and the main body module (100) may operate in conjunction with each other while being spaced apart from each other through the communication units (160, 250).

[0135] The function module (200C) may further include an input / output unit (270). The input / output unit (270) may include an input interface for receiving user commands. For example, the input interface may include a plurality of buttons for receiving user commands. The input / output unit (270) may include an output interface for displaying various screens related to the operation of the charging module. For example, the output interface may include a display. The display may be implemented as various displays such as an LCD (Liquid Crystal Display), an OLED (Organic Light Emitting Diodes), etc. For example, the output interface may include a speaker for providing audio information.

[0136] Fig. 31 is a drawing for explaining the operation of an air purifier (1) according to various embodiments.

[0137] Referring to FIGS. 1, 2, and 31, the main body module (100) may be configured to operate differently depending on the function modules (200A, 200B, 200C). For example, the module detection sensor (180) of the main body module (100) may be configured to detect the type of the function module (200). For example, the module detection sensor (180) may be an NFC (Near Field Communication) sensor configured to identify an NFC (Near Field Communication) tag mounted on the function modules (200A, 200B, 200C). The main control unit (130) may identify the NFC tags mounted on different function modules (200A, 200B, 200C) through the module detection sensor (180), thereby identifying the function modules (200A, 200B, 200C) assembled to the main body module (100). However, the type of sensor is not limited to this, and can be applied in various ways as long as it can identify the access of the function module (200A, 200B, 200C) or the function module (200).

[0138] The module detection sensor (180) of the main body module (100) can detect the type of the function module (200A, 200B, 200C). For example, the module detection sensor (180) can detect the type of the function module (200A, 200B, 200C) arranged on the upper part of the main body module (100). For example, the module detection sensor (180) can detect whether the function module (200A, 200B, 200C) arranged on the upper part of the main body module (100) is a blower module, a humidifying module, or a charging module. The module detection sensor (180) can detect whether the function module (200A, 200B, 200C) assembled to the main body module (100) is a blower module, a humidifying module, or a charging module.

[0139] Based on the information detected by the module detection sensor (180), the operation of the main body module (100) can be controlled. The main control unit (130) can control the operation of the main body module (100) differently depending on the type of the detected function module (200A, 200B, 200C).

[0140] For example, when the function module (200A) assembled in the main body module (100) is detected as a blower module performing a blower function by the module detection sensor (180), the main control unit (130) can adjust the rotation speed of the blower unit (120) of the main body module (100). For example, the main control unit (130) can adjust the rotation speed of the blower unit (120) of the main body module (100) in consideration of the operation of the function module (200A).

[0141] For example, when the function module (200B) assembled to the main body module (100) is detected as a humidifying module performing a humidifying function by the module detection sensor (180), the main control unit (130) can adjust the rotation speed of the blower unit (120) of the main body module (100). For example, when the amount of humidification by the function module (200B) is low, the main control unit (130) can reduce the rotation speed of the blower unit (120) or maintain it at a low state.

[0142] For example, when the function module (200C) assembled in the main body module (100) is detected as a charging module performing a charging function by the module detection sensor (180), the main control unit (130) can adjust the rotation speed of the blower unit (120) of the main body module (100). For example, the rotation speed of the blower unit (120) can be adjusted in consideration of changes in the air flow path due to the arrangement of the function module (200C), changes in the temperature of the surrounding air, etc.
