Detailed Description

Hereinafter, some embodiments of the present invention will be described in detail with reference to the exemplary drawings. When reference numerals are given to constituent elements in the drawings, the same reference numerals are given to the same constituent elements even when they are shown in different drawings. In describing the embodiments of the present invention, when it is determined that specific descriptions of known structures or functions may hinder understanding of the embodiments of the present invention, detailed descriptions thereof will be omitted.

Also, the terms first, second, A, B, (a), (b), etc. may be used in describing the constituent elements of the embodiments of the present invention. These terms are only used to distinguish one constituent element from another constituent element, and are not used to limit the substance, order, or sequence of the corresponding constituent elements, or the like. When it is described that one constituent element is "connected" or "connected" to another constituent element, the constituent element may be directly connected or connected to the other constituent element, but other constituent elements may also be "connected", "combined", or "connected" between the constituent elements.

As shown in fig. 1, the humidification purification device 1 according to the present inventive concept includes a case 10 forming an external appearance. The housing 10 may be formed in a cylindrical shape. In addition, the housing 10 may be configured such that an upper portion has a smaller diameter than a lower portion so as to be stably disposed on the ground. That is, the housing 10 may have a conical shape with a cut end.

The case 10 includes a separating portion 11, and two components constituting the case 10 are coupled to the separating portion 11 or separated from the separating portion 11. The housing 10 further includes a hinge portion (not shown) provided on the opposite side of the separating portion 11.

A stopper (not shown) may be provided at a portion where the two components are joined, that is, the separating portion 11. The blocking means may comprise a blocking protrusion or a magnetic member.

In this case, the two components can be relatively rotated about the hinge portion. In addition, if at least any one of the two components is rotated, the housing 10 can be opened. The housing 10 is opened so that the internal components can be replaced or repaired.

The housing 10 is formed with an intake portion 12 for taking in air. The suction unit 12 includes a through hole formed through at least a part of the housing 10.

The suction portions 12 are formed uniformly in a circumferential direction along the outer circumferential surface of the housing 10 so that air can be sucked in any direction with respect to the housing 10. That is, the air can be sucked in the 360-degree direction with reference to the center line in the vertical direction passing through the center of the inside of the casing 10.

In this way, the housing 10 is formed in a cylindrical shape, and the plurality of suction portions 12 are formed along the outer circumferential surface of the housing 10, so that the suction amount of air can be increased. Thus, by avoiding the hexahedral shape having the angular portion, there is an effect that the flow resistance to the sucked air can be reduced.

The air sucked through the suction portion 12 may flow in a substantially radial direction from the outer circumferential surface of the housing 10. In the following, the direction is defined. With reference to fig. 1, the vertical direction is referred to as the axial direction, and the horizontal direction is referred to as the radial direction. The axial direction may correspond to a motor shaft direction of a fan described later.

The radial direction may be a direction perpendicular to the axial direction. The circumferential direction may be a virtual circular direction formed by rotating around the axial direction and a distance in the radial direction as a radius of rotation.

A display device 30 and a discharge grid 22 forming a discharge portion 21 are provided on the upper portion of the housing 10. The display device 30 may be configured to display an operation state of the humidification/purification device 1.

The display device 30 may be provided with a power supply unit 31 for turning ON/OFF the humidification/purification device, and a plurality of input units 32 for selecting an operation mode and the like. In this case, as shown in the figure, the power supply unit 31 and the input unit 32 may be provided in a button type.

The flow of air will be described, and the air sucked into the humidification/purification device 1 from the suction portion 12 radially inward is discharged from the humidification/purification device 1 in the axial direction from the discharge portion 21. That is, the air can flow through the housing 10 in the axial direction from the radial direction.

FIG. 2 is a schematic sectional view of II-II' of FIG. 1. Fig. 2 is a diagram schematically showing the internal configuration of the humidification/purification apparatus 1.

As shown in fig. 2, the humidification/purification device 1 is provided with

air blowing modules

40 and 41 for forcibly flowing air.

The air supply unit includes a fan 40 for generating air flow and a fan motor 41 for supplying power to the fan 40. The fan motor 41 may be coupled to an upper side of the fan 40.

The fan 40 includes a centrifugal fan that discharges air from the upper side in the radial direction after air is introduced in the axial direction. Specifically, the fan 40 includes a hub 43 to which the rotating shaft 410 of the fan motor 41 is coupled, a wind shield 44 disposed apart from the hub 43, and a plurality of blades 42 disposed between the hub 43 and the wind shield 44. A fan inflow portion 45 for guiding inflow of air is formed at a lower portion of the fan 40.

The hub 43 may have a bowl (bowl) shape whose diameter becomes narrower toward the lower side. The hub 43 includes a shaft coupling portion to which the rotary shaft 410 is coupled, and a blade coupling portion extending obliquely upward from the shaft coupling portion.

The wind deflector 44 includes a lower end portion in which a wind deflector suction portion is formed and a blade coupling portion extending upward from the lower end portion, and air passing through the fan inflow portion 45 is sucked into the wind deflector suction portion.

One surface of the blade 42 may be coupled to the blade coupling portion of the hub 43, and the other surface may be coupled to the blade coupling portion of the wind shield 44. Further, a plurality of the blades 42 may be arranged in a circumferential direction of the hub 43.

Also, the humidification purification device 1 according to the present inventive concept includes a humidification module 50 that humidifies flowing air. As shown in fig. 2, the humidifying unit 50 is located above the

blower units

40 and 41.

The humidifying assembly 50 includes a humidifying filter 52. The humidification filter 52 is made of a water-absorbing and air-permeable material. That is, the humidifying filter 52 may absorb the supplied water, and the air may vaporize the absorbed water when passing through the humidifying filter 52. Therefore, the air sucked from the suction unit 12 passes through the humidification filter 52 which absorbs water, and humidification can be performed.

The humidifying module 50 will be described in detail later.

Also, the humidification purification device 1 according to the present inventive concept may further include a purification assembly 60 purifying the flowing air. In this case, the above-described purge assembly 60 may be omitted according to the structure and need.

The cleaning assembly 60 includes an air cleaning filter 62. The air cleaning filter 62 is formed in a cylindrical shape and may have a filter surface for filtering air. In particular, the air cleaning filter 62 is located inside the suction portion 12 formed along the outer circumferential surface of the housing 10. Thereby, the air sucked from the suction part 12 can pass through the air cleaning filter 62.

As shown in fig. 2, the cleaning module 60 is located below the blowing

modules

40 and 41.

That is, the purge module 60, the

blower modules

40 and 41, and the humidification module 50 are sequentially disposed in the casing 10 in the axial direction. At this time, the air sucked from the suction unit 12 passes through the purge module 60, the

blower modules

40 and 41, and the humidifying module 50, and is discharged from the discharge unit 21.

That is, the air flowing into the housing 10 may be discharged after passing through the air cleaning filter 62 and the humidifying filter 52 in sequence. Thus, the humidification/purification device 1 can purify and humidify the indoor air.

Fig. 3 is a schematic view of a humidifying assembly of a humidifying and purifying device according to a first embodiment of the present invention, and fig. 4 is a split schematic view of the humidifying assembly of the humidifying and purifying device according to the first embodiment of the present invention.

As shown in fig. 3 and 4, the humidifying unit 50 further includes humidifying elevating

devices

56 and 58 for moving the water tank 54 and the humidifying filter 52. In this case, the humidifying filter 52 is disposed above the water tank 54.

The water tank 54 is provided as a container for storing water. More specifically, the water tank 54 may be formed in a cylindrical shape with an open upper portion.

Also, referring to fig. 2, the humidifying assembly 50 further includes a water tub 59, and the water tub 59 is detachably coupled to the water tub 54. The water tub 59 may store a predetermined amount of water therein. The size and shape of the water tub 59 are not limited, and may be set to various sizes and shapes.

The water tank 54 includes a water tank coupling part 540 coupled to the water tank 59. Therefore, one side of the water tub 59 may be inserted into the water tub coupling part 540. And, water may flow from the water tub 59 to the water tub 54 so that the water stored in the water tub 54 maintains a predetermined water level.

The humidifying filter 58 may be disposed outside the water tub 59 so as to surround the water tub 59. In fig. 3 and 4, the water tub 59 is omitted for convenience of illustration, and only a frame structure forming the outer shape of the humidifying filter 52 is illustrated. The moisture-absorbing and air-permeable material humidification surface may be bonded to such a frame structure.

In detail, the humidifying filter 52 includes first and second humidifying frames 520 and 522 having a circular shape, and a third humidifying frame 524 connecting the first and second humidifying frames 520 and 522.

In this case, the first humidification frame 520 forms a lower end portion of the humidification filter 52, and the second humidification frame 522 forms an upper end portion of the humidification filter 52. That is, the first humidification frame 520 and the second humidification frame 522 are disposed in a vertically separated state.

The diameter of the first humidification frame 520 is formed to be smaller than the diameter of the second humidification frame 522. Therefore, the humidifying filter 52 is formed in a bowl shape (bowl shape) as a whole, which is widened from the lower end toward the upper end.

The second humidification frame 522 is disposed adjacent to the inner surface of the casing 10. That is, the diameter of the second humidification frame 522 may be formed to be similar to the diameter of the case 10.

The diameter of the water tank 54 is formed to be larger than the diameter of the first humidification frame 520 and smaller than the diameter of the second humidification frame 522. Accordingly, the air flows radially outward of the water tank 54 and radially inward of the casing 10, and passes through the humidifying filter 52.

The

humidification elevating devices

56 and 58 move the humidification filter 52 up and down. Accordingly, the humidifying filter 52 may be disposed in any one of a first state in which at least a part thereof is immersed in the water stored in the water tank 54 and a second state in which it is separated from the water stored in the water tank 54.

The humidification elevating device includes a first elevating member 56 having an elevating guide 560 formed thereon and a second elevating member 58 coupled to the first elevating member 56 and having a humidification motor 580 provided thereon.

The first elevating member 56 may be formed in a cylindrical shape opened in the upper and lower directions. In this case, the first elevating member 56 is disposed adjacent to the inner surface of the housing 10 so as not to obstruct the flow of air. In particular, the first elevating member 56 is disposed radially outside the humidifying filter 52 and the water tank 54.

That is, the diameter of the first elevation member 56 may be formed to be close to the diameter of the housing 10. Since the first elevating member 56 is a moving part, it may be disposed at a predetermined interval in order to prevent interference with the inner surface of the housing 10.

The elevation guide 560 may be formed as a long groove penetrating the first elevation member 56. In detail, the elevation guide unit 560 is formed as a long groove extending in a circumferential direction.

The elevation guide unit 560 includes a first guide unit 562 and a second guide unit 564 formed above the first guide unit 562. The present invention further includes a third guide portion 566 connecting the first guide portion 562 and the second guide portion 564.

That is, the elevation guide unit 560 may extend to be disposed at different positions in the vertical direction. In detail, the first guide portion 562 and the second guide portion 564 linearly extend in the circumferential direction. On the other hand, the third guide portion 568 extends obliquely in a circumferential direction so as to connect the first guide portion 562 and the second guide portion 564 formed at different heights.

A plurality of elevation guide portions 560 are formed at the first elevation member 56 so as to be spaced apart in the circumferential direction. For example, four lifting guide portions 560 are formed at the same interval in the circumferential direction. In this case, the first guide portion 562 and the second guide portion 564 of each elevation guide portion 560 have the same height, that is, the same axial position.

The second elevation member 58 includes a circular first elevation frame 586 and a second elevation frame 588 extending radially outward from the first elevation frame 586.

The diameter of the first elevation frame 586 may correspond to the diameter of the water tank 54. In particular, first raising/lowering frame 586 may be disposed at a position corresponding to a lower end portion of water tub 54. That is, the second elevating member 58 may be disposed under the water tank 54.

The second elevation frame 588 extends radially outward of the first elevation frame 586 so as to be coupled to the first elevation member 56. The second lift frame 588 may be provided in plural numbers separated in the circumferential direction. For example, second lift frames 588 each separated by 60 degrees in the circumferential direction are shown in fig. 4.

In particular, the second elevation frame 588 may be coupled to a lower end portion of the first elevation member 56. Therefore, the first elevating member 56 may be provided to extend upward in the axial direction at a position corresponding to the lower end of the water tank 54.

The second elevation member 58 further includes a rack 584 provided along at least a portion of the first elevation frame 586, and a gear 582 communicating the rack 584 with the humidification motor 580.

The rack 584 is formed in a curved shape along the outer circumferential surface of the first lifter frame 586. In detail, the rack 584 may be disposed between the second lift frames 588. Referring to fig. 4, one of the second lift frames 588 that are separated by 60 degrees in the circumferential direction is omitted, and the rack 584 is disposed to extend approximately 60 degrees in the circumferential direction.

The gear 582 is coupled to a motor shaft 581 of the humidifying motor 580. In this case, the humidifying motor 580 is disposed such that the motor shaft 581 extends in the axial direction. Therefore, the gear 582 is rotatable in the circumferential direction about the motor shaft 581 extending in the axial direction.

At this time, the rack 584 is engaged with the gear 582 and is disposed to be in contact with the gear 582. Therefore, the rack 584 can be moved in the circumferential direction by the rotation of the gear 582. That is, the first lifter frame 586 provided with the rack 584 is movable in a circumferential direction.

In this case, the humidification filter 52 includes a mounting portion 528 which is placed on the elevation guide portion 560. As shown in fig. 4, the mounting portion 528 may be formed to extend outward in a radial direction from the second humidification frame 522.

The mounting portion 528 may be provided in plurality so as to be circumferentially spaced. In this case, the number and positions of the mounting portions 528 correspond to the number and positions of the elevation guide portions 560. That is, four of the mounting portions 528 may be formed at the same interval in the circumferential direction.

Referring to fig. 3, the mounting portion 528 may be placed on the elevation guide portion 560 to penetrate the first elevation member 56 and protrude outward. In this case, the mounting portion 528 is disposed apart from the inner wall of the housing 10 by a predetermined interval in order to prevent interference with the housing 10.

Next, based on the structure of the humidifying unit 50, the movement of the humidifying filter 52 will be described.

Fig. 5 is a schematic diagram of a first state of the humidifying assembly of the humidification purification device according to the first embodiment of the present invention, and fig. 6 is a schematic diagram of a second state of the humidifying assembly of the humidification purification device according to the first embodiment of the present invention. For the sake of easy understanding, the water tub 59 and one side of the humidifying assembly 50 are omitted in the drawings.

The humidifying filter 52 may be disposed in a first state in which at least a part thereof is immersed in the water stored in the water tank 54. Fig. 5 shows a case where the humidification filter 52 is arranged in the first state. In this case, the state in which the humidification filter 52 is disposed in the first state is referred to as a first state of the humidification module 50.

The humidifying filter 52 may be disposed in a second state separated from the water stored in the water tank 54. Fig. 6 shows a case where the humidification filter 52 is arranged in the second state. In this case, the state in which the humidification filter 52 is disposed in the second state is referred to as a second state of the humidification module 50.

Referring to fig. 5, the humidifying filter 52 is disposed such that the mounting portion 528 is placed on the first guide portion 562. At this time, the humidifying motor 580 is driven. Specifically, the humidifying motor 580 is configured as a stepping motor, and a predetermined pulse signal is input thereto.

Thereby, the gear 582 rotates, and the rack 584 engaged therewith moves. Specifically, the humidifying motor 580 is disposed in a state of being fixed to the housing 10, and the gear 582 is fixed to the motor shaft 581. Therefore, the gear 582 rotates at a fixed position, and the rack 584 engages therewith to move.

Thereafter, first lift frame 586 provided with rack 584 rotates. In detail, the first elevation frame 586 rotates in a circumferential direction by a predetermined angle around the water tank 56. The first and second elevation frames 586 and 588 rotate by a predetermined angle, and the first elevation member 56 coupled to the second elevation frame 588 rotates by a predetermined angle.

Thereby, the position of the elevation guide unit 560 is changed. In detail, the elevation guide unit 560 moves in a circumferential direction in accordance with the rotation of the first elevation member 56.

As the elevation guide 560 moves, the placement part 528 moves relatively along the first guide part 562. Thereby, the placement portion 528 reaches the third guide portion 566, and rises in the axial direction along the inclined third guide portion 566.

Thereafter, the placing part 528 may reach the second guide part 564. That is, the humidifying filter 52 is disposed in a state where the placing section 528 is placed on the second guide section 564 as shown in fig. 6. Accordingly, the humidification filter 52 may be raised by an amount corresponding to a difference in height between the first and

second guide portions

562 and 564.

In this case, the placement portion 528 may be fixed in the circumferential direction. The placement section 528 may slightly move in the circumferential direction due to friction between the elevation guide 560 and the placement section 528.

On the other hand, in the state shown in fig. 6, the humidification motor 580 is driven. At this time, the pulse signal opposite to the previous pulse signal is input to the humidification motor 580.

Thereby, the gear 582 rotates, and the rack 584 engaged therewith moves. At this time, the rack 582 is moved in the opposite direction to the previous direction.

Thereafter, the first lift frame 586 provided with the rack 584 rotates. The first and second elevation frames 586 and 588 rotate by a predetermined angle, and the first elevation member 56 coupled to the second elevation frame 588 rotates by a predetermined angle. Thereby, the position of the elevation guide unit 560 is changed.

As the elevation guide 560 moves, the placement part 528 moves relatively along the second guide part 564. Accordingly, the placement portion 528 reaches the third guide portion 566, and descends in the axial direction along the inclined third guide portion 566.

Thereafter, the placing part 528 may reach the first guide part 562. That is, the humidifying filter 52 is disposed in a state where the placement portion 528 is placed on the first guide portion 562 as shown in fig. 5. Accordingly, the humidification filter 52 may be lowered by an amount corresponding to a difference in height between the first and

second guide portions

562 and 564.

As described above, the humidification filter 52 can be immersed in the water stored in the water tank 56 and used only when the humidification/purification device 1 is driven in a mode required for humidification. In addition, when humidification is not necessary or after the humidification/purification device is turned off, the humidification filter 52 may be dried separately from the water stored in the water tank 56.

The humidification/purification device and the humidification filter may have various configurations. Next, a humidification purification device according to another embodiment of the present invention will be described. The same reference numerals as those used in fig. 1 to 6 denote the same components with a added thereto, and the description thereof will be referred to.

Fig. 7 is a schematic sectional view of a humidification purification device according to a second embodiment of the present invention. Fig. 7 is a schematic sectional view of the humidification purification device having the appearance shown in fig. 1.

As shown in fig. 7, the humidification purification device 1a according to the present inventive concept includes a housing 10a formed in a cylindrical shape. The housing 10a is formed with a suction portion 12a formed along an outer peripheral surface. A display device 30a and a discharge unit 21a are provided on the upper portion of the housing 10 a.

The humidification/purification device 1a is provided with

blower modules

40a and 41a for forcing air to flow. The blower unit includes a fan 40a for generating air flow and a fan motor 41a for supplying power to the fan 40 a.

The fan 40a includes a hub 43a to which the rotating shaft 410a of the fan motor 41a is coupled, a wind shield 44a disposed apart from the hub 43a, and a plurality of blades 42a disposed between the hub 43a and the wind shield 44 a. A fan inflow portion 45a for guiding inflow of air is formed at a lower portion of the fan 40 a.

The humidification/purification device 1a includes a humidification module 50a that humidifies the air flowing therethrough. As shown in fig. 7, the humidifying unit 50a is located below the

blower units

40a and 41 a.

The humidifying module 50a includes a cylindrical humidifying filter 52 a. In particular, the humidification filter 52a is disposed inside the casing 10a in which the suction unit 12a is formed. Therefore, the air sucked from the suction unit 12a may directly pass through the humidification filter 52 a.

The humidifying unit 50a will be described in detail below. Unlike the humidification/purification device 1 shown in fig. 1 to 6, the humidification/purification device 1a shown in fig. 7 does not separately include a purification unit.

Fig. 8 is a schematic view of a humidifying assembly of a humidifying and purifying device according to a second embodiment of the present invention, and fig. 9 is a split schematic view of the humidifying assembly of the humidifying and purifying device according to the second embodiment of the present invention.

As shown in fig. 8 and 9, the humidifying unit 50a further includes humidifying elevating

devices

56a and 58a for moving the water tank 54a and the humidifying filter 52 a. In this case, the humidification filter 52a is disposed above the water tank 54a, and the

humidification lifters

56a and 58a are disposed above the humidification filter 52 a.

The water tank 54a is formed in a size corresponding to the humidifying filter 52a so as to accommodate a lower portion of the humidifying filter 52 a. In particular, the water tank 54a is provided below the housing 10a, so that it can be more stably disposed.

The humidification lifting/lowering

devices

56a and 58a move the humidification filter 52a up and down. Thus, the humidifying filter 52a may be disposed in any one of a first state in which at least a part thereof is immersed in the water stored in the water tank 54a and a second state in which it is separated from the water stored in the water tank 54 a.

The humidification elevating device includes a first elevating member 56a having an elevating guide 560a formed thereon and a second elevating member 58a coupled to the first elevating member 56a and including a humidification motor 580 a.

The first elevating member 56a may be disposed at a radially outer side of an upper portion of the humidification filter 52 a. The first elevating member 56a may be configured to have a minimum axial length so as to prevent interference with the flow of air flowing from the suction portion 12 a.

The elevation guide 560a includes a first guide part 562a and a second guide part 564a formed on an upper side of the first guide part 562 a. The present invention further includes a third guide portion 566 connecting the first guide portion 562a and the second guide portion 564 a.

Referring to fig. 7, the second elevating member 58a is spaced upward from the upper end of the humidification filter 52 a. The second elevation member 58a includes a circular first elevation frame 586a and a second elevation frame 588a extending radially outward from the first elevation frame 586 a.

The second elevation member 58a further includes a rack 584a provided along at least a portion of the first elevation frame 586a, and a gear 582a for communicating the rack 584a and the humidification motor 580 a.

In this case, the humidifying filter 52a includes a mounting portion 528a which is placed on the elevation guide portion 560 a. Specifically, the humidification filter 52a may include an upper end frame 522a, and the attachment portion 528a may protrude radially outward from the upper end frame 522 a.

The vertical movement of the humidification filter 52 by the driving of the

humidification lifters

56a and 58a is the same as that described above, and therefore, the description thereof will be given and omitted here.

Fig. 10 and 11 are schematic views of a humidifying assembly of a humidifying and purifying device according to a third embodiment of the present invention. The same reference numerals are used for the components corresponding to fig. 1 to 6.

As shown in fig. 10 and 11, the humidifying unit 50 further includes a humidifying lift device 56 for moving the water tank 54 and the humidifying filter 52. In this case, the humidifying filter 52 is disposed above the water tank 54.

The water tank 54 is configured as a container for storing water. In detail, the water tank 54 may be formed in a cylindrical shape with an open upper portion.

The humidifying assembly 50 further includes a water tub 58 detachably coupled to the water tub 54. The water tub 58 may store a predetermined amount of water therein. The size and shape of the water tub 58 are not limited, and various sizes and shapes may be used.

Referring to fig. 2, the water tank 54 includes a water tank coupling part 540 coupled to the water tank 58. One side of the water tub 58 may be inserted into the water tub combining part 540. And, water may move from the water tub 58 to the water tub 54 to maintain the water stored in the water tub 54 at a predetermined level.

The humidifying filter 58 may be disposed outside the water tub 58 so as to surround the water tub 58. For convenience of illustration, only a frame structure forming the outer shape of the humidification filter 52 is shown in fig. 10 and 11. The frame structure may be combined with a moisture-absorbing surface made of a water-absorbing and air-permeable material.

The diameter of the first humidification frame 520 is smaller than the diameter of the second humidification frame 522. Therefore, the humidifying filter 52 is formed in a bowl shape (bowl shape) as a whole, which is widened from the lower end toward the upper end.

The second humidification frame 522 is disposed adjacent to the inner surface of the casing 10. That is, the diameter of the second humidification frame 522 may be configured to be similar to the diameter of the case 10.

The diameter of the water tank 54 is configured to be larger than the diameter of the first humidification frame 520 and smaller than the diameter of the second humidification frame 522. Accordingly, the air can flow to the outside in the radial direction of the water tank 54 and the inside of the casing 10, and pass through the humidification filter 52.

The humidification elevating device 56 is coupled to the humidification filter 52, and moves the humidification filter 52 up and down.

Thus, the humidifying filter 52 may be disposed in any one of a first state in which at least a part thereof is immersed in the water stored in the water tank 54 and a second state in which it is separated from the water stored in the water tank 54. Fig. 10 shows a case where the humidification filter 52 is arranged in the first state, and fig. 11 shows a case where the humidification filter 52 is arranged in the second state.

The humidification elevating device 56 includes a humidification motor 560 that provides a driving force, and a connection member that is coupled to the humidification motor 560 and the humidification filter 52.

In this case, the humidifying motor 560 may be coupled and fixed to the water tank 54. In detail, the humidifying motor 560 is fixed to an outer surface of the water tank 54. In particular, the humidifying motor 560 is provided such that a motor shaft 560a protrudes outward in a radial direction from the water tank 54.

The connection member includes a gear 562 that rotates by the driving of the humidifying motor 560, and a rack 564 that moves up and down in conjunction with the gear 562.

In detail, the gear 562 is coupled to a motor shaft 560a of the humidifying motor 560. That is, the gear 562 is rotatable around the motor shaft 560a extending in the radial direction.

The rack 564 is configured to engage with the gear 562 and to contact with the gear 562. In particular, the rack 562 is configured to extend in an axial direction. Therefore, the rack 562 is movable in the axial direction, i.e., in the vertical direction, by the rotation of the gear 562.

The connecting member has a frame structure connecting the rack 564 and the humidification filter 52. For example, a first connection frame 563 coupled to the upper end of the rack 564 and a second connection frame 565 coupled to the lower end of the rack 564 are provided.

The first and second coupling frames 563 and 565 are formed in a circular shape and are spaced apart from each other in the vertical direction by a distance corresponding to the length of the rack 564. In particular, the first and second connection frames 563 and 565 are disposed outside the water tank 54 so as to have a diameter larger than that of the water tank 54. Accordingly, interference between the first and second coupling frames 563 and 565 and the sink 54 according to the movement of the rack 564 can be prevented.

A third connecting frame 567 may be provided to connect the first and second connecting

frames

563 and 565. The third coupling frames 567 may be formed in a plurality of axially extending and circumferentially spaced apart.

The first and second coupling frames 563 and 565 are stably coupled to each other by the third coupling frame 567. That is, the first and second coupling frames 563 and 565 may be coupled to each other by the rack 564 and the third coupling frame 567.

In particular, the third connecting frame 567 may connect the first and second connecting

frames

563 and 565 and the humidification frames 520, 522 and 524. For example, as shown in the drawing, one end of the third connecting frame 567 is coupled to the first connecting frame 563, and the other end is coupled to the second humidification frame 522.

The movement of the humidification filter will be described with reference to fig. 10 and 11. In the state shown in fig. 3, the humidifying motor 560 is driven. Specifically, the humidifying motor 560 is configured as a stepping motor, and a predetermined pulse signal is input thereto.

Thereby, the gear 562 rotates, and the rack 564 ascends. The first to third coupling frames 563, 565, and 567 coupled to the rack 564 are raised. Then, the first to third humidification frames 520, 522, and 524 coupled to the third coupling frame 567 are lifted. That is, the humidification filter 52 is lifted and arranged in the state shown in fig. 4.

On the other hand, in the state shown in fig. 11, the humidification motor 560 is driven. At this time, the humidifying motor 560 receives a pulse signal in reverse to the previous pulse signal.

Thereby, the gear 562 rotates, and the rack 564 descends. The first to third connecting

frames

563, 565, and 567 and the first to third humidification frames 520, 522, and 524 coupled to the rack 564 are lowered. That is, the humidification filter 52 is lowered and arranged in the state shown in fig. 10.

As described above, the humidification purification device and the humidification filter according to the present invention may have various configurations, and the humidification elevating device may have various configurations corresponding thereto.

As shown in fig. 12, the humidification purification device 1 according to the present inventive concept is provided with a control part 70 which controls the above-described fan motor 41, the above-described humidification motor 560, and the like. The configuration shown in fig. 5 is an exemplary configuration, and the control section 70 can control a wider variety of devices.

For example, the control unit 70 may input a predetermined pulse signal to the humidification motor 560. Thereby, the humidifying motor 560 is driven in one direction, and the humidifying filter 52 can be raised and lowered as described above.

The controller 70 may control ON/OFF and intensity of the fan motor 41. Accordingly, the fan 40 rotates at a predetermined rotational speed, and forcibly blows air toward the casing 10.

The control unit 70 may control various devices based on signals transmitted from the power supply unit 31 and the input unit 32. The ON/OFF of the humidification/purification device 1 may be input through the power supply unit 31, and the intensity of the fan 40 or the mode of the humidification/purification device 1 may be input through the input unit 32.

For example, the humidification/purification device 1 may be driven in a humidification mode or a purification mode. In the humidification mode, the humidification filter 52 may be arranged in the state of fig. 10, and in the purge mode, the humidification filter 52 may be arranged in the state of fig. 11. Such a mode of operation is illustrated in detail in fig. 13.

Also, the humidification purification device 1 according to the present inventive concept includes a humidity sensor 72. The humidity sensor 72 is provided to measure the humidity of the space in which the humidification/purification device 1 is disposed. For example, the humidity sensor 72 may be disposed inside the casing 10 to measure the humidity of the sucked air.

The humidity sensor 72 may be provided in an external device. The humidity sensor 72 may be omitted, and the humidification/purification device 1 may receive information about humidity by connecting to a server or the like.

As shown in fig. 13, the humidification purification device 1 is turned ON (S10). In this case, the user can input the ON of the humidification/purification device 1 to the power supply unit 31. The humidification/purification device 1 may be turned ON by a signal from the humidity sensor 72, a pollution sensor (not shown), or the like.

As described above, the humidification purification device 1 described above can be operated in the humidification mode or the purification mode. For example, the humidification mode may be performed when a result of measuring the indoor humidity is lower than a reference value, and the purge mode may be performed when the indoor humidity is higher than the reference value.

When operating in the purification mode, the humidification filter 52 is separated from the water stored in the water tank 54 and does not move. Namely, the state shown in fig. 11 is fixed. Accordingly, the air is discharged in a state of being decontaminated after passing through the air cleaning filter 62 by the operation of the fan 40.

On the other hand, when the humidification/purification device 1 is driven in the humidification mode, the humidification filter 52 is lowered to be at least partially immersed in the water stored in the water tank 54 (S20). That is, the humidification filter 52 moves from the state of fig. 11 to the state of fig. 10. Specifically, the humidifying motor 560 is driven, and the connecting member 56 converts the rotational force of the humidifying motor 560 to lower the humidifying filter 52.

In addition, the humidifying filter 52 absorbs the water stored in the water tank 54. The fan 40 is driven to flow air into the housing 10 (S30). That is, the fan motor 41 is driven, and the fan 40 rotates at a predetermined rotational speed.

Specifically, air is sucked from the suction portion 12, and air is ejected from the ejection portion 21. The air sucked from the suction unit 12 passes through the humidification filter 52 and is discharged from the discharge unit 21. In this case, the water absorbed by the humidification filter 52 is converted into air, and the humidity of the air can be increased.

The air sucked from the suction unit 12 passes through the air cleaning filter 62 and the humidifying filter 52 in this order. This causes humidified and decontaminated air to be discharged from the discharge unit 21.

After operating in the humidification mode for a predetermined time, it is determined whether the indoor humidity corresponds to the reference value (S40). When the indoor humidity does not reach the reference value, the humidification mode is continuously operated, and when the indoor humidity exceeds the reference value, the humidification mode is ended.

When the humidification mode is completed, the humidification filter 52 is raised so that the humidification filter 52 is separated from the water stored in the water tank 54 (S50). That is, the humidification filter 52 moves from the state shown in fig. 10 to the state shown in fig. 11. Specifically, the humidifying motor 560 is driven, and the connecting member 56 converts the rotational force of the humidifying motor 560 to raise the humidifying filter 52.

Thereafter, the fan 40 is stopped (S60), and the humidification purifier 1 is turned OFF (S70). The fan 40 is continuously driven, and the humidification/purification device 1 can be operated in the purification mode.

In this case, the fan 40 may be stopped after the humidification filter 52 is lifted and operated for a predetermined time. This vaporizes all the water absorbed in the humidification filter 52, and maintains the purification of the humidification filter 52.

In this way, the humidifying filter 52 is used only by being immersed in the water stored in the water tank 56 when operating in the humidifying mode. After the humidification mode is finished, the humidification filter 52 may be separated from the water stored in the water tank 56 and dried.
