Description

air purifier

[0001] The present disclosure relates to an air purifier, and more particularly, to an air purifier with improved air purification performance and convenience.

[0002] An air purifier is a device that filters and expels the air within a space, thereby reducing dust and bacteria. An air purifier filters out foreign substances through the airflow within the space and expels the air free of these contaminants.

[0003] The air purifier can form an outlet at the top and cause the filtered air discharged upward to flow in all directions to quickly increase the cleanliness of the indoor space.

[0004] Additionally, when forming an outlet on the upper side, a separate fan for wind direction control can be placed on the upper side to send the filtered air to a long distance.

[0005] Additionally, research is underway on an air purifier configured with multiple stages by stacking the blower devices vertically.

[0006] Prior art (Korean Patent Publication No. KR10-2022-0007365) relates to an air purifier circulator, and discloses an air purifier that transmits a clean air stream to a long distance by placing a circulator on blower devices arranged in a vertical direction.

[0007] The air purifier in the prior literature has a problem in that the stepper motor for rotating the circulator is placed within the flow path, partially blocking the flow path area, thereby reducing the air purification performance.

[0008] Additionally, the air purifier in the prior literature could generate vibration because the fan of the circulator is connected to the shaft of the motor and rotates.

[0009] In addition, since the circulator is screwed to the main body of the air purifier below, it is difficult to disassemble, so there is a disadvantage in that it is difficult to clean if dust accumulates on the grill, internal flow path, and fan of the main body of the air purifier.

[0010] The problem that the present disclosure seeks to solve is to provide an air purifier in which a booster module can be easily separated and mounted.

[0011] The problem that the present disclosure seeks to solve is to provide an air purifier whose internal components are easy to maintain and repair.

[0012] The problem that the present disclosure seeks to solve is to provide an air purifier that can circulate discharged clean air over a longer distance.

[0013] The problem that the present disclosure seeks to solve is to provide an air purifier capable of improving air purification performance by rotating a booster module without shielding the internal flow path.

[0014] The problem that the present disclosure seeks to solve is to provide an air purifier capable of reducing vibration and noise of a booster module.

[0015] The problem that the present disclosure seeks to solve is to provide an air purifier that can improve air purification performance by preventing discharged clean air from being re-inflowed.

[0016] The problem that the present disclosure seeks to solve is to provide a miniaturized air purifier that prevents backflow without adding a structure such as a partition plate.

[0017] The problem that the present disclosure seeks to solve is to provide an air purifier capable of forming an airflow that effectively removes allergen substances that cause allergies.

[0079] Additionally, while terms such as "first" and "second" may be used in this specification to describe various elements, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0080] FIG. 1 is a perspective view of an air purifier according to an embodiment of the present disclosure. FIG. 2 is a cross-sectional view of an air purifier according to an embodiment of the present disclosure, and FIG. 3 is a diagram showing air flow in an air purifier according to an embodiment of the present disclosure. FIG. 4 is an exploded view of an air purifier according to an embodiment of the present disclosure.

[0081] Referring to FIGS. 1 to 4, the air purifier (1) includes a case (10) forming an exterior. The case (10) has suction holes (11a, 12a) formed on the circumferential surface so that air can be sucked in from various directions. Air can be sucked in from 360 degrees based on a vertical center line passing through the inner center of the case (10). A plurality of suction holes (11a, 12a) are formed spaced apart from each other in the circumferential direction. The plurality of suction holes (11a, 12a) are evenly formed in the circumferential direction along the circumferential surface of the case (10) so that air can be sucked in from any direction based on the case (10).

[0082] Meanwhile, in this specification, the up-down direction or vertical direction is defined as the axial direction. The axial direction may correspond to the central axis direction of the blower fan (140, 240) described later, i.e., the motor axis direction of the fan. In addition, the radial direction or horizontal direction may be understood as a direction perpendicular to the axial direction. In addition, the circumferential direction may be understood as the direction of an imaginary circle formed when rotating with the axial direction as the center and the radial distance as the rotation radius.

[0083] An air purifier (1) includes an air purification module (100, 200) that generates air flow. The air purification module (100, 200) includes a blower fan (140, 240) arranged inside a case (10) and a filter (120, 220) that removes foreign substances in the air flowing in through an intake port (11a, 12a).

[0084] Air flowing into the intake port (11a, 12a) can pass through the filter (120, 220). The filter (120, 220) is provided in a cylindrical shape and may have a filter surface for filtering air.

[0085] The case (10) may have a cylindrical shape. The case (10) may include a first case (11) having a semi-cylindrical shape and covering a portion of the outer surface of the air purification module (100, 200), and a second case (12) having a semi-cylindrical shape and covering the remaining portion of the outer surface of the air purification module (100, 200).

[0086] Alternatively, the case (10) may have a conical shape (a truncated cone shape), and the first case (11) and the second case (12) may each have a semi-conical shape.

[0087] The first case (11) and the second case (12) can be combined to form the exterior of the air purifier (1). The first case (11) covers the front of the air purifier (1) and may be referred to as a "front case" or "front cover." The second case (12) covers the rear of the air purifier (1) and may be referred to as a "rear case" or "rear cover."

[0088] The suction ports (11a, 12a) include a first suction port (11a) formed in the first case (11) and a second suction port (12a) formed in the second case (12). The suction ports (11a, 12a) connect the inside and the outside of the case (10). A plurality of suction ports (11a, 12a) are formed. The case (10) can form a plurality of suction ports (11a, 12a) on its peripheral surface.

[0089] A plurality of suction ports (11a, 12a) are formed evenly in the circumferential direction along the outer surface of the case (10) so that air can be sucked in from any direction based on the case (10).

[0090] The plurality of suction ports (11a, 12a) are formed in a stripe shape extending vertically. Alternatively, the plurality of suction ports (11a, 12a) may be formed by perforating in a circular or oval shape.

[0091] In this way, the case (10) is configured in a cylindrical shape, and a plurality of suction ports (11a, 12a) are formed along the outer surface of the case (10), so that the amount of air sucked in can increase.

[0092] Meanwhile, referring to FIGS. 1 to 4, the air purification module (100, 200) includes a first air purification module (100) and a second air purification module (200) arranged in a vertical direction.

[0093] For example, the second air purification module (200) may be arranged above the first air purification module (100). Since the first air purification module (100) is arranged at the bottom of the air purifier (1), it may be called a “lower air purification module” or “lower module,” and since the second air purification module (200) is arranged at the top of the air purifier (1), it may be called an “upper air purification module” or “upper module.”

[0094] The first air purification module (100) and the second air purification module (200) each include a blower fan (140, 240) and a filter (120, 220) that removes foreign substances in the air flowing in through the intake port (11a, 12a).

[0095] The first air purification module (100) includes a first blower fan (140) and a first filter (120) that removes foreign substances in the air flowing into the intake port. In addition, the first air purification module (100) further includes a first motor (130) that rotates the first blower fan (140).

[0096] The second air purification module (200) includes a second blower fan (240) and a second filter (220) that removes foreign substances in the air flowing into the intake port. In addition, the second air purification module (200) further includes a second motor (230) that rotates the second blower fan (240).

[0097] Meanwhile, the air purification module (100, 200) includes a first discharge port (110a) formed at the bottom and a second discharge port (210a) formed at the top. The first discharge port (110a) is formed at the bottom of the first blower fan (140) and the first filter (120). The second discharge port (210a) is formed at the top of the second blower fan (240) and the second filter (220). Air from which foreign substances have been removed in the filter (120, 220) is discharged downward through the first discharge port (110a) and upward through the second discharge port (210a).

[0098] When the second air purification module (200) is placed above the first air purification module (100), the first discharge port (110a) is formed at the bottom of the first air purification module (100), and the second discharge port (210a) is formed at the top of the second air purification module (200).

[0099] Additionally, a lower discharge grill (110) including multiple grills and designed to guide lower airflow is disposed at the lower end of the first air purification module (100). Additionally, an upper discharge grill (210) including multiple grills and designed to guide upper airflow is disposed at the upper end of the second air purification module (200).

[0100] The upper discharge grill (210) may each include a cylindrical inner wall (211) and an outer wall (212). The plurality of grills of the upper discharge grill (210) may each connect the inner wall (211) and the outer wall (212) and may be arranged in a radial structure.

[0101] The lower discharge grille (110) may include a plurality of grilles having a concentric circle structure. The plurality of grilles may be a plurality of circles having the same center and different radii. The plurality of grilles may each include a section that is bent outward in the radial direction. The lower discharge grille (110) may include a plurality of grilles that are bent outward at a predetermined angle. The lower discharge grille (110) may be arranged at the discharge port (110a) to transmit downward discharge airflow laterally.

[0102] A bottom plate (170) is placed on the lower side of the first air purification module (100). The bottom plate (170) is placed so as to contact the ground and supports the air purification module (100, 200).

[0103] On the upper surface of the bottom plate (170), a flow guide (170a) is arranged to laterally guide air discharged downward through the first discharge port (110a). The bottom plate (170) may further include a base (170b) that supports the flow guide (170a). The flow guide (170a) may be formed on the upper surface of the base (170b). In addition, the flow guide (170a) and the base (170b) may be combined to form the bottom plate (170).

[0104] Air from which foreign substances have been removed in the first filter (120) is discharged downward through the first discharge port (110a). Air from which foreign substances have been removed in the second filter (220) is discharged upward through the second discharge port (210a).

[0105] According to the present disclosure, even if two air purification modules are stacked vertically, air is not discharged upward from the lower air purification module. Therefore, by forming suction ports (11a, 12a) on the peripheral surface of the case (10), suction performance can be improved, while preventing air discharged from the lower air purification module from being re-introduced into the upper air purification module.

[0106] Conventional two-stage air purifiers have a problem in that the discharge airflow of the lower air purification module is configured to be directed upward, which reduces air purification performance due to re-intake of the purified airflow. In the present disclosure, the discharge airflow direction of the lower air purification module is changed to downward, thereby preventing a backflow and improving air purification performance.

[0107] In addition, according to the present disclosure, since the air purifier (1) product does not have a mechanical structure for preventing a return airflow and a configuration for discharge, the product can be made more compact and the degree of freedom in design, such as the arrangement of internal components, can be improved.

[0108] For example, by positioning the control module (400) at the center of the air purifier (1) product, the length of the power and signal wires and the connection structure can be made more efficient, and the overall product height can be reduced. In addition, by positioning the control module (400) between the air purification modules (100, 200) and controlling the air purification modules (100, 200) with a single integrated control module (400), the air purification modules (100, 200) do not each have a control module, so the overall product height can be reduced.

[0109] Meanwhile, the particle size of general allergen substances is on the order of 3 to 100 ㎛, and since it is larger than fine dust, it has the property of settling to the bottom. Therefore, the airflow for floating allergen particles and capturing them with the filter (120, 220) can be implemented through the lower airflow discharged downward by the first air purification module (100). Therefore, allergen substances that cause allergies can be effectively removed through the lower airflow discharged downward by the first air purification module (100).

[0110] Meanwhile, the air purifier (1) may be equipped with a UVC LED (not shown) that outputs ultraviolet rays of a wavelength band that has a sterilizing effect on bacteria, mold, and microorganisms, and an ionizer (not shown) that eliminates bacteria and mold by passing electricity inside the case (10).

[0111] Meanwhile, the air purification module (100, 200) includes a fan housing (145, 245) that accommodates a blower fan (140, 240), and a plurality of support parts (150, 250) that extend vertically from the fan housing (145, 245). The support parts (150, 250) may extend in the length direction based on the air purifier (1) product. The number of support parts (150, 250) may vary depending on the model size and specifications. In addition, some of the support parts (150, 250) may be configured to have at least one different shape, size, or material from the rest.

[0112] A wire cover (155, 255) covering the support (150, 250) may be placed on at least one side of a plurality of support members (150, 250). The support members (150, 250) and the wire cover (155, 255) may be spaced apart from each other to form a space in which wires, etc. may be placed.

[0113] In addition, the air purification module (100, 200) may further include a wire cover (115, 215) in which wires, etc. can be placed. The motors (130, 230) may be accommodated in the motor fastening portions (125, 225), respectively.

[0114] The air purification module (100, 200) includes a filter mounting portion (160, 260) on which a filter (120, 220) is mounted, and a control module (400) is placed between the filter mounting portions (160, 260).

[0115] Net steel (165, 265) is placed between the filter (120, 220) and the blower fan (140, 240) to prevent the body or other objects from entering the space where the blower fan (140, 240) is placed.

[0116] Meanwhile, a top cover (270) is placed on the top of the combined case (10). An upper discharge grill (210) is placed on the inside of the top cover (270).

[0117] Meanwhile, a booster module (300) that controls the wind direction of air discharged through the second discharge port (210a) may be placed on the upper side of the air purification module (100, 200). A booster module (300) that changes the discharge direction of air flow generated from the second air purification module (200) may be placed on the upper side of the second air purification module (200).

[0118] The booster module (300) can send the air discharged from the second air purification module (200) over a longer distance. In addition, the booster module (300) can blend airflows by rotating left and right, thereby forming various airflows. Depending on the embodiment, the booster module (300) can also move in an up and down direction to form a more diverse airflow.

[0119] The booster module (300) can be detachably mounted on the top of the second air purification module (200). In addition, a contact power structure is applied to the booster module (300) and the second air purification module (200), so that when mounted, power can be supplied from the second air purification module (200) to the booster module (300).

[0120] When cleaning of parts within the booster module (300), such as the booster fan (330), is required, or when cleaning of the upper discharge grill (210) at the top of the second air purification module (200), etc. is required, the hygienic aspect can be enhanced by separating and managing the booster module (300).

[0121] The booster module (300) includes an outer cover (320), an inner grill (355) disposed on the inner side of the outer cover (320) and having an outlet (see 355a in FIG. 5) formed therein, a rear suction grill (311) having an intake (see 311a in FIG. 6) formed therein, a booster fan (330) disposed on the front side of the rear suction grill (311) and on the inner side of the inner grill (355), and a motor (340) that rotates the booster fan (330).

[0122] The rear suction grille (311) may be a part of the rear cover (310) that forms the exterior of the rear of the booster module (300). Alternatively, the rear suction grille (311) may be provided separately and combined with the rear cover (310).

[0123] The rear cover (310) may have an opening formed through which the upper part of the booster neck (360) passes. In addition, the rear cover (310) may be joined to the booster neck (360) using a predetermined fastening member.

[0124] The booster module (300) is supported by a booster neck (360) and can be mounted on the second air purification module (200).

[0125] The booster module (300) may be provided to be movable. The booster module (300) may be in an inclined upright position or in a lying down position, as illustrated in FIG. 1.

[0126] The booster module (300) further includes a display panel (390) arranged on the front of the booster fan (330). The display panel (390) can cover the entire front of the booster fan (330). The motor (340) can be arranged on the inside of the booster fan (330).

[0127] The booster fan (330) may be a sirocco fan. While a radial fan is used to discharge airflow through the front grill, a sirocco fan can discharge airflow through the inner grill (355) on the side. Accordingly, a display panel (390) can be placed on the front of the fan to obscure the fan structure. In addition, a sirocco fan has the advantage of reducing noise compared to a radial fan.

[0128] In addition, the booster module (300) further includes an internal flow guide (350) that is arranged between the outer cover (320) and the inner grill (355) and changes the flow direction of air discharged through the discharge port (355a) of the inner grill (355).

[0129] A slit (351) is formed between the inner euro guide (350) and the display panel (390). Air discharged through the discharge port (355a) of the inner grill (355) passes through the slit (351) and is discharged from the booster module (300).

[0130] FIG. 5 is an assembly diagram of a booster module according to an embodiment of the present disclosure, and FIGS. 6 and 7 are exploded views of a booster module according to an embodiment of the present disclosure.

[0131] FIG. 8 is a cross-sectional view of a booster module according to an embodiment of the present disclosure, and FIG. 9 is a drawing showing airflow of a booster module according to an embodiment of the present disclosure.

[0132] Referring to FIGS. 5 to 9, a display panel (390) displaying operating information of the air purifier (1) is positioned on the front of the booster module (300). The display panel (390) can move together with the booster module (300). The user can better view the information displayed on the display panel (390) at the top of the product.

[0133] A booster fan (330) and a booster motor (340) are arranged on the rear side of the display panel (390). The booster motor (340) is arranged inside the booster fan (330). The display panel (390) covers the entire front side of the booster fan (330) and the booster motor (340), so that the booster fan (330) is not exposed to the user.

[0134] More preferably, the booster fan (330) may be a sirocco fan. When a slit fan is used, the flow is forward, making it unsuitable for a slit-shaped flow path, requiring a front grille. However, when a sirocco fan is used, the discharge flow resistance to the slit structure is reduced, which is advantageous for the slit structure. Accordingly, the bottom grille can be omitted, and the fan and inner grille are not visible from the outside.

[0135] The rear cover (310) and the outer cover (320) are combined to form a space for accommodating components inside. A booster fan (330) and a booster motor (340) can be placed in the inner space of the outer cover (320).

[0136] An inner grill (355) in which an outlet (355a) is formed and an internal flow guide (350) that changes the direction of air flow discharged through the outlet (355a) of the inner grill (355) are placed between the outer cover (320) and the booster fan (330).

[0137] The inner grille (355) is positioned on the side of the booster fan (330). Air flow due to the rotation of the booster fan (330) occurs along the inner grille (355) outlet (355a) on the side and the internal flow guide (350).

[0138] An internal flow path (352) including a forwardly curved surface is arranged on the inner surface of the internal flow path guide (350). An end of the internal flow path guide (350) and an end of the display panel (390) are spaced apart at a predetermined interval to form a slit (351).

[0139] The air discharged through the discharge port (355a) of the inner grill (355) passes through the internal passage (352) and the slit (351) and is discharged from the booster module (300).

[0140] According to the present disclosure, dust accumulation on the booster fan (330) and grill (355) is improved by discharging the airflow through the slit (351), and the aesthetic aspect is improved by making the fan (330) and grill (355) invisible from the outside.

[0141] According to the present disclosure, airflow is transmitted through the inner grille (355), internal flow path (352), and slit (351) on the side of the booster fan (330), so that the blades of the booster fan (330) are not visible from the outside, and the size of the motor (340) can also be reduced. In addition, according to the present disclosure, the problem of dust accumulating on the front grill can be improved by removing the front grill.

[0142] The rear cover (310) includes a joining portion (312) that is joined to the outer cover (320) and a grill portion (311) in which an intake port (311a) is formed. The grill portion (311) includes a plurality of grills and may be the rear intake grill (311) described above. The rear surface of the outer cover (320) may be configured to correspond to the shape and joining structure of the joining portion (312). For example, when the rear cover (310) and the outer cover (320) are joined, a step portion may be formed at the rear surface of the outer cover (320) so that the outer lines are smoothly connected, and a joining member that is joined to the joining portion (312) may be arranged at the step portion. Meanwhile, the outer cover (320) may be joined to the inner flow guide (350) by the joining member on the inner surface.

[0143] The configuration from the front display panel (390) to the rear suction grill (311) located at the top of the air purifier (1) can also be called a “booster head.”

[0144] The booster module (300) / booster head is coupled to and supported by the booster neck (360). In addition, the booster neck (360) is coupled to the air purification module (100, 200), which is the main body of the air purifier (1).

[0145] The booster neck (360) can be connected to the uppermost part of the second air purification module (200). Accordingly, at least a portion of the clean air flow discharged through the second discharge port (210a) formed at the upper end of the second air purification module (200) can be introduced into the suction port (311a) of the rear suction grill (311).

[0146] The upper part of the booster neck (360) can be combined with the booster module (300). The lower part of the booster neck (360) can be connected to the second air purification module (200). To facilitate connection between the booster neck (360) and the second air purification module (200), a protrusion protruding downward can be formed on the lower part of the booster neck (360).

[0147] A head rotation part (380) may be located at the lower side of the booster neck (360). The head rotation part (380) may be located on the inner side of the inner wall (211) of the upper discharge grill (210). The head rotation part (380) may include a structure for rotating the booster module (300), a case for accommodating internal components, etc., and may be connected to or accommodate components such as a stepper motor, ionizer, and wires.

[0148] The upper part of the head rotation part (380) can be coupled with the booster neck (360). The lower part of the head rotation part (380) can be coupled with another mechanical structure of the second air cleaning module (200). For example, the lower part of the head rotation part (380) can be coupled to the upper part of the second fan housing (245). Alternatively, the lower part of the head rotation part (380) can be coupled to the upper part of the second motor coupling part (225). In another embodiment, a separate coupling part (not shown) may be provided between the lower part of the head rotation part (380) and the upper part of the second fan housing (245) or the second motor coupling part (225).

[0149] Meanwhile, the booster module (300) includes a power module (370). The power module (370) may include a wire for power supply, a signal wire for signal transmission, and a terminal connected to the wire and signal wire.

[0150] When the booster module (300) is mounted on the second air purification module (200), the terminal of the power module (370) comes into contact with the terminal of the second air purification module (200) and can receive power from the second air purification module (200).

[0151] FIG. 10 is a drawing for reference in the description of a fan motor module of a booster module according to one embodiment of the present disclosure.

[0152] Referring to FIG. 10, the booster fan (330) and booster motor (340) described above may be formed integrally to form a fan motor module (330, 340). The booster motor (340) may be positioned at the center inner side of the booster fan (330). At least a portion of the rotating part (341) of the booster motor (340) may be positioned at the center inner side of the booster fan (330).

[0153] The booster fan (330) may be a Sirocco fan. Additionally, the booster motor (340) may be an external rotor motor in which the rotor is located outside the stator.

[0154] The fan motor module (330, 340) can be formed as an integral body by inserting at least a portion of the rotating part (341) of the booster motor (340) into the central recessed part (331) of the booster fan (330).

[0155] The product size can be reduced by configuring the fan / motor module (330, 340) in which the booster fan (330) and the booster motor (340) are integrated. In addition, since the rotating part (341) of the booster motor (340) and the booster fan (330) are integrated, vibration caused by the difference in balance of the fan / motor can be eliminated.

[0156] FIG. 11 is a cross-sectional view of a booster module according to an embodiment of the present disclosure, FIG. 12 is a bottom view of a booster module according to an embodiment of the present disclosure, and FIG. 13 is a drawing referenced in an explanation of rotational drive of a booster module according to an embodiment of the present disclosure.

[0157] Referring to FIGS. 11 to 13, the booster neck (360) supports the booster module (300) from the lower side. A head rotation part (380) is coupled to the lower side of the booster neck (360).

[0158] The head rotation part (380) includes a rotation part upper case (381) and a rotation part lower case (382) located below the rotation part upper case (381). A rotation bearing (290), various types of wires (1110), etc. can be accommodated in the space formed between the rotation part upper case (381) and the rotation part lower case (382).

[0159] The upper case (381) can be coupled with the booster neck (360). The lower case (382) can be coupled with other mechanical structures of the second air purification module (200). For example, the lower end of the lower case (382) can be coupled to the upper end of the second fan housing (245). Alternatively, a separate coupling portion (not shown) may be provided between the lower end of the lower case (382) and the upper end of the second fan housing (245).

[0160] Meanwhile, the upper discharge grill (210) at the top of the second air purification module (200) has a ring shape with an open center, and a structure for coupling with the booster module (300) is arranged in the central opening, and a plurality of grills forming a second discharge port (210a) are arranged on the periphery. The plurality of grills can connect the inner wall (211) and the outer wall (212) and can be arranged in a radial structure.

[0161] The booster neck (360) may be coupled with the rear cover (310) and / or the outer cover (320). A portion of the booster neck (360) may penetrate the opening of the rear cover (310) and the remainder may be located on the lower side of the rear cover (310).

[0162] To avoid blocking the airflow discharged from the upper discharge grill (210), the booster neck (360) and the head rotation part (380) are coupled on the inside of the upper discharge grill (210). At least a portion of the head rotation part (380) can rotate together with the booster module (300).

[0163] The booster neck (360) and the head rotation part (380) are joined at the central opening of the upper discharge grill (210). That is, the booster neck (360) and the head rotation part (380) can be joined between the cylindrical inner wall (211) of the upper discharge grill (210).

[0164] A motor (345) that rotates the booster module (300) in the first direction is arranged inside the booster neck (360). Since the motor (345) is located inside the booster neck (360), which is a support structure of the booster module (300), it does not shield the internal flow path of the second air purification module (200) leading to the discharge port (210a) of the upper discharge grill (210).

[0165] The motor (345) generates a driving force for the rotation of the booster module (300). For example, the motor (345) may be a step motor whose rotation angle can be easily controlled. In addition, the motor (345) may include a motor capable of bidirectional rotation.

[0166] A first gear (346) is connected to the motor (345). The first gear (346) can be coupled to the motor shaft of the motor (345). The first gear (346) can be connected to the motor (345) and rotate.

[0167] Meanwhile, the first gear (346) is gear-coupled to the second gear (347). The second gear (347) is linked to the first gear (346) and may extend in a circular manner in the circumferential direction. The second gear (347) serves as a guide rail for guiding rotational motion and is formed with a plurality of gear teeth. The first gear (346) is also formed with a plurality of gear teeth. The second gear may be a type of rack gear arranged in a circular arc shape. When the motor (345) is driven, the first gear (346) engages with the second gear (347) and rotates.

[0168] As the motor (345) is driven, the first gear (346) rotates and engages the second gear (347). At this time, since the second gear (347) has a fixed configuration, the first gear (346) can move along the second gear (347).

[0169] Meanwhile, the motor (345) may be positioned eccentrically from the rotation axis of the booster module (300). The first gear (346) may be rotated with a set rotation radius around the rotation axis. The second gear (347) may be formed with a length corresponding to the rotation amount or rotation angle of the booster module (300).

[0170] Depending on the driving of the motor (345), the booster module (300) can rotate in a first direction. The first direction can be a clockwise or counterclockwise direction with respect to the axial direction of the second blower fan (240). When the motor (345) rotates, the first gear (346) can rotate. The motor (345) rotates clockwise or counterclockwise with respect to the axial direction of the second blower fan (240), and correspondingly, the first gear (346) can rotate clockwise or counterclockwise.

[0171] For example, if the motor (345) rotates clockwise, the first gear (346) can move counterclockwise. On the other hand, if the motor (345) rotates counterclockwise, the first gear (346) can move clockwise.

[0172] Depending on the clockwise or counterclockwise movement of the first gear (346), the booster module (300) can rotate in the same direction as the movement direction of the first gear (346).

[0173] Meanwhile, a rotation bearing (290) may be located on the lower side of the upper case (381). The rotation bearing (290) may reduce frictional force generated during the first direction rotation process of the booster module (300).

[0174] According to one embodiment of the present disclosure, the booster module (300), the booster neck (360), and the upper case (381) can rotate according to the rotation of the motor (345).

[0175] The motor (345) for rotating the booster module (300) is built into the central booster neck (360) structure rather than the euro, thereby reducing flow resistance and improving air purification performance.

[0176] Meanwhile, the second air purification module (200) includes a wire (1110) passing through a hole formed in the upper case (381) and the lower case (382) and a first terminal (1120) connected to the wire (1110) and exposed on the upper side of the upper case (381).

[0177] The power module (370) of the booster module (300) includes a second terminal (371) that contacts the first terminal (1120) on the upper side of the upper case (381).

[0178] The second terminal (371) of the power module (370) is exposed to the lower side of the booster neck (360) and can come into contact with the first terminal (1120) of the second air purification module (200).

[0179] According to an embodiment, the air purifier (1) may further include a switch (not shown) that can turn power supply on / off when the second terminal (371) and the first terminal (1120) are in contact.

[0180] When the booster module (300) is mounted on the top of the second air purification module (200), the second terminal (371) of the booster module (300) and the first terminal (1120) of the second air purification module (200) come into contact. When the second terminal (371) and the first terminal (1120) come into contact with each other in the contact power structure of the booster module (300) and the second air purification module (200), current can flow from the second air purification module (200) to the booster module (300).

[0181] The power module (370) receives power from the second air purification module (200) through the second terminal (371). In addition, the power module (370) can supply power to the display panel (390), booster motor (340), booster fan (330), etc.

[0182] The booster motor (340) and the booster fan (330) may be integrated to form a fan motor module (330, 340). The fan motor module (330, 340) is disposed on the inner side of the outer cover (320) and the inner grill (355). In addition, the fan motor module (330, 340) is disposed on the front side of the rear cover (310) and the rear suction grill (311).

[0183] Meanwhile, the first and second terminals (1120, 371) may include a power terminal for supplying power and a signal terminal for transmitting a signal, respectively. That is, the first and second terminals (1120, 371) may perform the role of transmitting signals as well as transmitting power.

[0184] The booster module (300) is intended to transmit clean airflow to a long distance, but if the motor, which is a rotating component for controlling the direction of the airflow, is located inside the flow path (1300), there is a problem in that the flow path is partially (e.g., 15%) blocked, thereby generating flow resistance and reducing air purification performance. Referring to Fig. 13, conventionally, the motor was positioned in a position to block a portion of the flow path (1300) through which the clean airflow rises. Accordingly, the motor and gear structure became obstacles that hindered the airflow. As the flow of air blocked by the motor and gear structure occurred left and right, it hindered the flow of rising air, thereby increasing the flow resistance.

[0185] In the present disclosure, the motor (345) for rotating the booster module (300) is placed inside the booster neck (360), thereby improving the euro resistance by opening the inside of the euro (1300) so that it is not blocked by the motor and gear structure.

[0186] In addition, according to the present disclosure, the energy required for information display and rotation of the booster module (300) can be supplied with a contact power structure, and the separation and mounting of the booster module (300) can also be easily implemented.

[0187] FIG. 14 is a drawing for reference in the description of mounting and dismounting of a booster module according to one embodiment of the present disclosure.

[0188] Referring to FIG. 14, the booster neck (360) may include a lower cover (1410) forming a bottom surface and a ring-shaped first outer portion (1420) disposed on the outer side of the periphery of the lower cover (1410).

[0189] The first outer portion (1420) may protrude downwardly from the lower cover (1410). A hook (1425) for connection with the second air purification module (200) is arranged on the side of the first outer portion (1420) that protrudes downwardly from the lower cover (1410).

[0190] The bottom cover (1410) may have a portion of the bottom cover opened so that the second terminal (371) of the power module (370) is exposed downward. The second terminal (371) may penetrate the opening of the bottom cover (1410) and be exposed downward.

[0191] An upper discharge grill (210) forming an outlet (210a) is arranged at the top of the second air purification module (200). The upper discharge grill (210) may include a cylindrical inner wall (211) and an outer wall (212), and a plurality of grills arranged in a radial structure between the inner wall (211) and the outer wall (212).

[0192] An upper case (1450) and a lower case (1440) are arranged inside the upper discharge grill (210). The lower case (1440) can be located below the upper case (1450).

[0193] One side of the lower case (1440) may be a ring-shaped portion with an open center. Additionally, the side and rear surfaces supporting the ring-shaped portion may form a space for accommodating a wire connected to the first terminal (1460). In Fig. 14, the end of the ring-shaped outer portion of the lower case (1440) is shown exposed upward.

[0194] In response to the bottom structure of the booster neck (360) in which the first outer portion (1420) disposed on the outer side of the periphery of the lower cover (1410) protrudes and a hook (1425) protrudes from the inner surface of the first outer portion (1420), the upper case (1450) may be positioned higher than the ring-shaped outer portion of the lower case (1440). Meanwhile, a joining member (not shown) coupled with the hook (1425) may be arranged on the side of the upper case (1450).

[0195] The booster module (300) can be fixed to the second air purification module (200) with a hook (1425) structure. In addition, the booster module (300) can be easily detached upward, so that the user can easily clean the rear intake grill (311) and the upper discharge grill (210) after detaching the booster module (300).

[0196] Meanwhile, the upper case (1450) may be the above-described upper case (381) of the rotating part, and the lower case (1460) may be the above-described lower case (382) of the rotating part.

[0197] FIGS. 15 and 16 are exploded views of a booster module according to an embodiment of the present disclosure, and FIGS. 17 to 22 are drawings for reference in explanations regarding mounting and dismounting of a booster module according to an embodiment of the present disclosure.

[0200] The booster fan (330) may be placed on the lower side of the display base (395) so as not to be exposed to the user. The booster fan (330) may be a Sirocco fan.

[0201] The booster motor (340) is placed inside the booster fan (330). The booster motor (340) may be an external motor.

[0202] A rear cover (310) and an outer cover (320) are combined to form a space for accommodating components therein. A booster fan (330), a booster motor (340), an inner grill (355) in which an outlet (355a) is formed, and an internal flow guide (350) for changing the direction of air flow discharged through the outlet (355a) of the inner grill (355) may be arranged in the inner space of the outer cover (320). The rear cover (310) may include a rear suction grill (311).

[0203] The booster module (300) can be detachably mounted on the upper side of the second air purification module (200).

[0204] The booster neck (360) supports the booster module (300) and can be coupled to the upper side of the second air purification module (200). The booster neck (360) can be coupled to the mechanical structure of the second air purification module (200) on the inner side of the upper discharge grill (210).

[0205] A head rotation part (380) may be positioned at the lower side of the booster neck (360). The head rotation part (380) includes a rotation part upper case (381) and a rotation part lower case (382) positioned below the rotation part upper case (381). A rotation bearing (290), etc. may be accommodated in a space formed between the rotation part upper case (381) and the rotation part lower case (382). In addition, wires may be connected to a power module (370), a motor (345), an ionizer (1510), etc. through the head rotation part (380).

[0206] A motor (345) that generates power for the rotation of the booster module (300) may be placed inside the booster neck (360). The motor (345) may be placed inside the booster neck (360) so as not to block the upper discharge airflow of the second air purification module (200). The motor (345) may be a step motor whose angle can be easily adjusted.

[0207] The upper case (381) can be coupled to the booster neck (360), and the lower case (382) can be coupled to the upper side of the second fan housing (245).

[0208] The booster module (300) includes a pair of fasteners (1600) that are coupled to an outer cover (320). The pair of fasteners (1600) may be located on the lower side of a booster head (1700) supported by a booster neck (360).

[0209] A pair of fasteners (1600) each include a support (1610, 1620) coupled to an outer cover (320), a spring (1613, 1623) coupled to the support (1610, 1620), and a plate (1615, 1625) coupled to the spring (1613, 1623).
