Description

Apparatus for both humidification and air cleaning

The present invention relates to a humidifying and cleaning device.

The air conditioner includes an air conditioner for controlling the temperature of the air, an air purifier for maintaining cleanliness by removing foreign substances from the air, a humidifier for providing moisture in the air, and a dehumidifier for removing moisture in the air.

Conventionally, a humidifier is classified into a natural evaporation type in which water is atomized in a diaphragm, and a natural evaporation is performed in a vibration type and a humidifying filter which discharge water into the air.

The natural evaporative humidifier includes a disk type humidifier in which a disk is rotated using a driving force and water is naturally evaporated from the surface of the disk in the air and a humidifying filter type humidifier which is naturally evaporated by air flowing in a humidifying medium Respectively.

In the conventional humidifier, a part of the air flowing in the humidification process was filtered through the filter. That is, since the conventional humidifier has a humidifying function as its main function, the function of purifying the air is weak and the filtering function is added in the humidifying process. Conventionally, the humidifier has large particles of water generated so as to be sprayed into the intake air, so that a large droplet can be discharged to the outside through the discharge port.

Also, the conventional humidifier can not be operated only for air cleaning. Therefore, humidification is performed when the user desires air cleaning even in a high humidity condition.

Conventionally, a humidifier, an air cleaner, and the like provide an operation state of a product sensed by an internal sensor or the like through a display unit or the like. Thus, the user can confirm that the product is operating normally.

However, since the user can not visually confirm the humidification process or the air cleaning process, the user can not intuitively grasp the operation state of the device. Therefore, the recognition of the internal pollution degree is not immediate, and the contamination state can be grasped and cleaned only when the product is dismantled periodically.

In addition, a conventional rotary atomizing apparatus for spraying water by centrifugal force and collecting air sucked is disclosed in the conventional air cleaner. However, in the conventional air cleaner, the water jetting amount varies depending on the water height, so that the dust accumulation varies, and a large droplet is discharged into the discharge port to pollute the surroundings. And it is difficult to perform a humidifying function by using a rotary atomizing device for the purpose of dust collection.

The following is a list of prior literature information.

1 to 3, a humidifying and cleaning device 1 according to an embodiment of the present invention includes a blowing unit 100 for providing a flow pressure of air, a flow guide 100 connected to a lower side of the blowing unit 100, A filter unit 300 connected to a lower side of the flow guide 200 to suck outside air, a humidifying medium 350 for humidifying air passing through the filter unit 300, a humidifying medium 350 A receiving part 500 for receiving the water receiving part 400; a driving part 550 for providing a driving force; a base 600 installed inside the driving part 400; A water tub guide 700 for collecting water supplied to the humidifying medium 350, and a spray module 800 for spraying water by rotating under the driving force of the driving unit.

The air evacuating part 100 can provide a suction force for sucking outside air, and can also provide a discharge pressure that can suck the sucked air to be discharged to the outside through humidification or cleaning. That is, the airflow 100 provides a pressure to flow air.

A flow guide 200 for guiding the flow of air to the inflow portion 100 may be positioned below the inflow portion 100. For example, the flow-through portion 100 may be removably stacked on the upper end of the flow guide 200.

The flow guide 200 can be formed in a cylindrical shape with its top and bottom opened. The inner surface of the flow guide 200 may be curved so that the inner diameter of the flow guide 200 becomes narrower toward the center from the upper and lower ends of the flow guide 200.

In addition, the inside of the flow guide 200, which is formed by the outer side surface and the inner side surface of the flow guide 200, may be hollow. For example, the flow guide 200 may be formed in a donut shape. A detailed description thereof will be described later.

The filter unit 300 may be positioned below the flow guide 200. The flow guide 200 may be removably stacked on the filter unit 300. For example, the outer diameter of the filter unit 300 may be equal to the outer diameter of the flow guide 200. Therefore, the lower end of the flow guide 200 can be mounted on the upper end of the filter unit 300.

The filter unit 300 may include a HEPA filter.

The filter unit 300 is formed with a suction passage through which the outside air is sucked, and the outside air sucked through the suction passage can flow into the humidifying medium 350. That is, the outside air can be sucked in the filter unit 300 in all directions 360 degrees.

delete

Since the outside air sucked into the filter unit 300 is filtered while passing through the filter unit 300, the suction channel may be regarded as a first filtering channel.

The humidifying medium 350 may be positioned at a certain distance in the center of the filter unit 300.

It is preferable that water flowing down after wetting the humidifying medium 350 is stored in the water receiving part 400. That is, it is preferable that water flowing down after wetting the humidifying medium 350 is disposed so as not to flow out of the water tank 400. Thus, the humidifying medium 350 may be located inside the filter unit 400 to provide humidification to the filtered air passing through the filter unit 400.

The humidifying medium 350 may form a humidifying passage for humidifying the filtered air passing through the filter unit 300. The filtered air can be humidified by receiving moisture while passing through the humidification channel.

The humidifying medium 350 is soaked in water, and the wetted water is naturally evaporated.

The filtered air passing through the humidifying medium (350) is humidified by receiving moisture from the water receiving section (400). That is, the filtered air passing through the filter unit 400 and supplied to the humidifying medium 350 passes through the humidifying medium 350. This is because it is advantageous for humidification that the filtered air passes through the humidifying medium 350.

Specifically, in the embodiment of the present invention, the filtered air is humidified by the water that is naturally evaporated. The natural evaporation refers to the evaporation of water in the absence of additional heat. As the contact with air increases, as the flow rate of air increases, the lower the pressure in the air, the more natural evaporation is promoted. The natural evaporation may be referred to as natural vaporization. Therefore, the humidifying medium 350 promotes natural evaporation of water.

On the other hand, the humidifying medium 350 is immersed in water, but is not immersed in the water receiving part 400. The water impregnated with the humidifying medium 350 sufficiently flows down to the water receiving part 400 and can be stored or reused.

The air having passed through the humidifying medium 350 can be filtered, collected and humidified once again by the water sprayed from the spray module 800. Accordingly, the flow path through which the air having passed through the humidifying medium 350 flows can be understood as a second filtration flow path.

In addition, the filter unit 300 and the humidifying medium 350 may be installed on the upper side of the water tank guide 700 and may be removably installed. Details related to this will be described later.

A water supply hole 755 may be formed at the center of the water tub guide 700 to prevent interference with the spray module 800 and to recover a part of the water supplied to the humidifying medium 350.

At the lower side of the water tub guide 700, a receiving part 500 and a water receiving part 400 formed of a material through which the user can see the inside can be positioned.

In another aspect, the upper end of the injection module 800 may be positioned higher than the water tub guide 700.

The upper end of the receiving part 500 may be detachably coupled to the water tub guide 700.

The receiving portion 500 may be formed in a cylindrical shape with the upper side thereof opened. The receiving portion 500 may be formed with a water tank coupling opening so as to open along the semicircular side of the bottom surface to allow the water receiving portion 400 to be drawn in and out.

The water receiving portion 400 is coupled to the receiving portion 500 and is located inside the receiving portion 500. Further, a water repellent coating may be formed on the inner surface of the water receiving portion 400. When the water-repellent coating is formed, it is possible to prevent the droplet from spreading widely, and to make the shape of the droplet more round.

And may be detachably coupled to the receiving portion 500 in the receiving portion 400. [ That is, a water tank coupling is formed in the receiving part 500 so that the water receiving part 400 is detachably stored.

The receiving unit 400 may be installed to be slidable in the receiving unit 500. Therefore, when the water receiving portion 500 is drawn out from the receiving portion 500, the receiving portion 500 is slidably moved along the bottom surface of the receiving portion 500 So as to protrude outwardly from the water tank coupling. That is, the water receiving unit 400 can be inserted into or drawn out of the receiving unit 500 through the water tank coupling.

The injection module 800 sucks water in the water receiving part 400 and sucks the sucked water upward so that the pumped water can be sprayed onto the humidifying medium 350 and the side wall of the water receiving part 400 have.

The injection module 800 includes a water supply hole 755 formed at an opening of the central portion of the coupling guide 700 and a central axis of the receiving portion 500 and connected to the driving portion 550, . Accordingly, the injection module 800 can rotate the water in the water receiving part 400 to sweep upward and spray the water, thereby wetting the humidifying medium 350.

The injection module 800 supplies water to the humidifying medium 350 and visualizes the humidifying process. That is, the injection module 800 injects water into the water receiving part 400 to collide with the water, and the collided water is scattered to realize a rain view.

The rain-view refers to a situation in which droplets formed on the inner surface of the water receiving part 400 appear as if a raindrop flows down.

The spray module 800 rotates the spraying housings 820 and 840 to suck water in the water receiving part 400 and pump the sucked water upward. The injection module 800 injects the pumped water radially outward. A detailed description thereof will be described later.

The bottom of the water receiving part 400 may be formed with a bottom opening 410 with a predetermined diameter to avoid interference with the injection module 800 when sliding. The bottom opening 410 may be formed at the center of the bottom surface of the water receiving portion 400. Details related to this will be described later.

The injection module 800 is positioned on the central axis of the receiving part 500, the water receiving part 400 and the coupling guide 700 when the receiving part 400 is drawn into the receiving part 500 .

A base 600 for fixing the receiving part 500 can be positioned below the receiving part 500. The receiving portion 500 may be removably stacked on the base 600.

The base 600 may have a cylindrical shape with an open top. The base 600 may be a supporting part of the humidifying and cleaning device 1 and directly contact the ground or the like, or a wheel may be provided to movably support the humidifying and cleaning device 1.

A driving unit 550 for transmitting a driving force to the injection module 800 may be installed in the base 600. The driving unit 550 may include a driving motor and a power transmission shaft 555 for transmitting the rotational force of the driving motor. That is, a driving motor is installed in the base 600, and rotational force can be transmitted to the injection module 800 through the driving motor.

Meanwhile, at the center of the bottom surface of the receiving part 500, a sealing function is performed to avoid the influence of water supplied to the receiving part 400 and protect the driving part 550, and at the same time, the power transmission shaft 555 And may include a column 510 protruding upward to support the column.

A hole is formed in the upper end of the column 510 to connect the driving unit 550 to transmit the rotational force to the injection module 800. A power transmission shaft 555 connected to the driving motor of the driving unit 550 is connected to the hole And may transmit the rotational force by being coupled with the injection module (800).

The humidifying medium 350, the water receiving unit 400, the receiving unit 500, the water collecting unit 500, and the humidifying unit 500 are installed in the humidifying and cleaning apparatus according to the embodiment of the present invention. The driving unit 550, the base 600, the water tub guide 700, and the injection module 800 may be referred to as a humidifying and purifying unit.

That is, the humidifying and cleaning device 1 according to the embodiment of the present invention can be largely constituted of a blowing unit 100 and a humidifying and filtering unit disposed below the blowing unit 100.

The air evacuating part 100 provides a suction force for sucking outside air. The humidifying / cleaning unit filters the sucked outside air and humidifies the filter air to provide moisture. The humidifying air passing through the humidifying / purifying unit is discharged to the outside by the blowing unit (100).

4 is an exploded perspective view showing a blower of a humidifying and cleaning device according to an embodiment of the present invention.

Referring to FIG. 4, the inflow portion 100 may be positioned above the flow guide 200.

The airflow guide part 100 includes a shroud support part 10 provided on the upper side of the flow guide 200, a shroud 20 supported by the shroud support part 10, A vane part 40 installed inside the vane part 30 to guide the air discharge direction of the air passing through the air blowing fan assembly 30, 40 for guiding air to be discharged to the outside.

The shroud support part 10 is located on the upper side of the flow guide 200 and can be installed along the outer diameter of the flow guide. The shroud support 10 may support the loudspeaker 20 below the shroud 20. For example, the shroud support 10 may be formed in a disc shape having open top and bottom.

In detail, the lower end of the upper layer part is mounted on the upper side of the shroud support part 10, and the lower end part of the lower layer part can be mounted on the upper side of the flow guide 200 and supported. That is, the shroud support part 10 can be understood as a case covering the space formed between the shroud 20 and the flow guide 200.

The blower fan assembly 30 may be installed inside the shroud 20. In detail, the blowing fan assembly 30 may be installed inside the lower layer portion to guide air passing through the humidifying medium 350 to the discharging portion 50.

The blowing fan assembly 30 may include a centrifugal fan. The blowing fan assembly 30 may further include a blade 31 for changing the flow of air through rotation and a fan motor 35 for providing a rotating force to the blade 31.

The blade 31 is connected to the fan motor 35 and can be rotated by receiving the driving force of the fan motor.

The apparatus may further include a blade housing (not shown) that defines a space between the blades 31 and the fan motor 35 and connects upper ends of the plurality of blades 31 to suck air from the lower side .

The blade housing may be integrally formed with a plurality of blades.

The plurality of blades 31 may be spaced along the circumference of the fan motor 35. Here, in order to minimize installation space, the fan motor 35 may be positioned in the inner depression space formed by the blade housing, and a plurality of blades 31 may be positioned outside the opposite surface.

The fan motor 35 is located at the center of the blowing fan assembly 30 and rotates the rotation axis of the fan motor downward to easily secure a space for sucking and flowing the lower air by the rotation of the blade 31 .

FIG. 5 is an exploded perspective view showing a humidifying / cleaning unit of the humidifying / cleaning apparatus according to the embodiment of the present invention, FIG. 6 is an enlarged view of 'A' of FIG. 3, Fig.

5 to 7, as described above, the flow guide 200 can be formed into a cylindrical shape with its top and bottom opened. The inner surface of the flow guide 200 may be formed as a curved surface having a narrowed circumference of the open space from the upper end and the lower end of the flow guide 200 toward the center.

The flow guide 200 may be stacked on the filter unit and the humidifying medium. A suction passage may be formed to allow the air sucked through the filter unit to be sucked into the blowing fan assembly. That is, the air sucked into the filter unit 300 by the flow guide 200 closely connected to the upper end of the humidifying medium 250 flows through the humidifying medium 350 into the blowing fan assembly .

The flow guide 200 may include a seating rib 230 protruding along a circumference of an inner center portion. That is, the minimum inner diameter of the flow guide 200 may be a circle formed by the seating rib 230.

The upper end of the humidifying medium 350 may be seated on the seating rib 230 to be fixedly supported.

The flow guide 200 includes an upper guide surface 210 forming a curved surface such that an inner diameter of the flow guide 200 is increased upward and a lower guide surface 220 forming a curved surface of an inner diameter of the flow guide 200 . That is, the inner side surface of the flow guide 200 is defined as the upper guide surface 210 with respect to the seating rib 230, and the lower side surface is defined as the lower guide surface 220. Accordingly, the flow guide 200 can be formed in a donut shape.

The seating rib 230 and the lower guide surface 220 guide the air sucked into the filter unit 400. In detail, since the humidifying medium 350 and the inner surface of the flow guide are closely supported by the seating rib 230, the filtered air passing through the filter unit 400 flows along the dew surface 220, It can not flow to the upwardly blown portion 100 without passing through the medium 350. Therefore, air passing through the filter unit 400 can flow to the humidifying medium 350 along the lower guide surface 220.

Similarly, the upper guide surface 210 serves to guide the air that has passed through the humidifying medium 350. In detail, the air passing through the humidifying medium 350, that is, the humidifying air, can flow upward to the blowing unit 100. At this time, a lower portion of the shroud 20 can be closely fixed to the upper end of the upper guide surface 210. Therefore, all of the humidifying air flowing upward along the upper guide surface 210 flows into the shroud 20 and is sucked in the axial direction of the blowing fan assembly 30 installed inside the shroud 20, And can be discharged in the radial direction.

In addition, the inside of the flow guide 200, which is formed by the outer side surface and the inner side surface, may be hollow. According to this, the effect of cost reduction and weight reduction can be obtained.

Meanwhile, as described above, the filter unit 300 and the humidifying medium 350 are located on the upper side of the water tub guide 700 and can be detachably installed. Hereinafter, the water tank guide 700 will be described in detail.

The water tank guide 700 includes a filter seating surface 710 for fixing and supporting the filter unit 300, a first drainage guide 730 for guiding water recovered from the outside of the humidification medium 350, And a drain hole 740 formed to allow water flowing along the first drain guide 730 to flow into the receiver 400.

The filter seating surface 710 can be formed along the outer diameter of the water tub guide with a constant width. The filter seating surface 710 may form the highest position on the upper surface of the water tub guide 700.

The filter seating surface 710 may have various shapes depending on the type of the filter unit 300.

The lower surface of the filter unit 300 is mounted on the filter mounting surface 710 and the upper surface of the filter unit 300 is mounted on the flow guide 200 to support the filter unit 300 . For example, a coupling groove may be formed on the filter seating surface 710 so that the filter unit 300 is positioned and fixed. Of course, the coupling means for fixing the filter unit 300 may be variously proposed.

The first drainage guide 730 may be formed as a downward inclined surface from the filter seating surface 710 toward the center of the water tub guide 700.

The first drainage guide 730 can guide the droplets discharged from the outer side surface of the humidifying medium 530 to flow toward the center of the inside of the water tub guide along the inclined surface so that the droplets are not discharged to the outside.

When a liquid droplet ejected by the flow pressure by the injection module 800 is discharged toward the outward direction of the humidifying medium 350, the liquid droplet is discharged from the inner surface of the filter portion 300 and the outer surface of the humidifying medium 350 . ≪ / RTI > At this time, since the first drainage guide 730 is formed as a downward inclined surface in the center direction, the risk that the droplet flows out to the outside through the filter unit 300 can be prevented.

Since the droplet that flows inward along the first drain guide 730 is collected at the lower end of the outer side surface of the humidifying medium 350 and easily flows into the drain hole 740, It can be easily done.

The first drainage guides 730 may be formed in a plurality of holes. The plurality of first drainage guides are located between the filter seating surface 710 and the humidifying medium seating surface 720. The plurality of first drainage guides 730 are spaced apart from each other at regular intervals . In addition, the plurality of first drainage guides 730 may be disposed radially with respect to the central axis.

The first drainage guide 730 may have an upper end abutting the filter seating surface 710 and a longer arc than the lower end abutting the humidifying medium seating surface 720. Since the upper end of the first drainage guide 730 is connected to the filter inner surface 710 at a position higher than the lower end, the droplet falling to the outer side of the humidifying medium 350 can flow toward the inner center.

The drain hole 740 may be located on both side portions of the first drainage guide 730. In addition, another first drainage guide 730 is disposed on both side portions of the first drainage guide 730, and the drainage hole 740 is spaced apart from the first drainage guide 730 by a plurality of first drainage guides 730 Can be formed in the spacing space.

The drain hole 740 is formed to communicate with the water receiving portion 400 so that the droplet flowing down to the outer side portion of the humidifying medium 350 is guided by the first drainage guide 730, The large droplet is collected at the lower end of the guide 730 to form a large droplet that flows into the drain hole 740 and drops into the receiver 400 or directly into the drain hole 740, (400) and can be recovered.

The shape of the drain hole 740 may be variously formed. For example, the drain hole 740 may be formed as a whole as a spaced space formed by the plurality of first drainage guides 730. Alternatively, a part of the spacing space may be shielded along the inclination of the first drainage guide 730 and only the lowermost position may be opened.

The water tank guide 700 includes a humidifying medium seating surface 720 for holding and supporting the humidifying medium 350, a second water drain guide 750 for guiding water recovered from the inside of the humidifying medium 350, And a water supply port 755 formed to allow water flowing along the second drainage guide 750 to flow into the water receiving part 400.

The humidifying medium seating surface 720 may be formed to support the lower surface of the humidifying medium 350 in a fixed manner.

The humidifying medium seating surface 720 may have a smaller diameter than the diameter of the filter seating surface 710. And may be formed along the inner diameter of the water tub guide 700 with a constant width at a position lower than the filter receiving surface 710.

The lower surface of the humidifying medium 350 is fixedly supported by the humidifying medium seating surface 720 and the upper surface of the humidifying medium 350 can be fixedly supported by the seating ribs 230 of the flow guide 200. [ have.

The coupling between the humidifying medium 350 and the humidifying medium receiving surface 720 may be performed by various means.

The second drainage guide 720 may extend along the inner diameter of the humidifying medium seating surface 720 so as to have a downward inclination toward the center.

Since the second drainage guide 720 has a downward inclined surface toward the center, a part of the droplet sprayed from the injection module 800 and a droplet flowing down from the inner surface of the humidifying medium 250 can flow into the receiving part 400 It can be easily dropped.

The water supply port 755 prevents the interference with the rotating injection module 800 and prevents the droplet flowing along the second drainage guide 720 from dropping into the water receiving part 400 at the center of the water tank guide 700 .

In other respects, the water supply port 755 can be understood as a hole formed by the inner diameter of the second drainage guide 72.

7, the water (see the dashed arrows) pumped by the injection module 800 is wetted with the humidifying medium 350, and the liquid droplets from the outside and inside of the humidifying medium 350, It is possible to flow downwardly. In addition, a droplet which is discharged to the outside of the humidifying medium 350 or can not reach the inside of the humidifying medium 350 may also flow downward.

At this time, the falling droplet is flowed into the drain hole 740 by the first drain guide 730 and falls (see a solid line arrow) to the receiver 400, or the second drain guide 750, (Refer to a solid line arrow) through the water supply port 755 to the water receiving portion 400.

That is, the water tank guide 700 may have a function of holding the filter unit 400 and the humidifying medium 350, as well as a function of collecting the water sprayed.

FIG. 8 is a partially assembled view showing a combined state of the water receiving part and the receiving part of the humidifying and cleaning device according to the embodiment of the present invention, and FIG. 9 is a sectional view cut along the line C-C 'of FIG.

Referring to FIGS. 8 and 9, as described above, the base 600 is provided with a driving unit 550 therein, and the receiving unit 500 is detachably stacked on the upper side.

The receiving part 500 accommodates the receiving part 400 and the receiving part 400 can be coupled to the receiving part 500 in a sliding manner. Further, the water tub guide 700 can be detachably stacked and coupled to the upper portion of the receiving portion 500.

The driving unit 550 may include a driving motor and a power transmission shaft 555 for transmitting the rotational force of the driving motor. The driving motor is located at the center of the base 600 and the power transmission shaft 555 passes through the central portion of the receiving floor 501 which is the bottom surface of the receiving portion 500, Lt; / RTI >

The receiving part 500 supports the power transmission shaft 555 coupled with the injection module 800 so that the power transmitting shaft 555 can rotate stably and includes a column 51 for protecting the water receiving part 400 from water filled therein can do.

The column 510 may extend upward from the center of the receiving floor 501 to enclose the power transmission shaft 555. For example, the column 510 may be formed in an inverted cup shape.

The receiving unit 500 may include a water tank coupling 400 for receiving the water receiving unit 400 because the water receiving unit 400 accommodated therein is drawn in and drawn out through sliding movement.

The water tank coupling may be formed such that the side surface of the receiving part 500 is opened along the periphery of the semicircle of the receiving floor 501. Therefore, interference with the receiving portion 500 can be avoided during the drawing and drawing of the receiving portion 400, so that the receiving portion 500 can slide easily.

The bottom surface of the water receiving part 400 may slide along the bottom surface of the receiving part 500.

Meanwhile, the size of the receiving unit 400 may be smaller than that of the receiving unit 500. As the outer diameter of the water receiving part 400 becomes smaller, the size of the opening of the water tub access hole can be reduced.

However, even when the outer diameter of the water receiving unit 400 is reduced, it is necessary to restrict the droplets falling by the water tank guide 700. That is, the minimum value of the outer diameter of the receiving portion 400 may be the inner diameter of the filter receiving surface 710. [

The water receiving part 400 includes a water tank center hole 410 which forms a hole in the center of the water tank bottom 401 which is the bottom surface of the water receiving part 400 in order to avoid interference with the column 510 can do. The water tub central hole 410 may have a predetermined size or more for smooth sliding movement of the water receiving unit 400.

The coupling method of the receiving unit 400 and the receiving unit 500 may be variously suggested. For example, when receiving the water receiving part 400, the receiving part may be coupled with the receiving part by a latch switch. At the time of withdrawing the receiving unit 400, the latch switch may be disassembled by pressing or pulling the user.

In addition, when the water receiving portion 400 is drawn into the accommodating portion 500, a latching rib may be formed to prevent the humidifying and cleaning device from being drawn out to the outside.

When the water receiving unit 400 is drawn out, the inner surface of the receiving unit 400 may be drawn out until the inner side of the receiving unit 400 is hooked by the injection module 800, Lt; / RTI >

In order to prevent the above-described risk of breakage, the size of the water tank center hole 410 may be set in advance. Accordingly, the water tank center hole 410 can be restricted to prevent the water tank 400 from being drawn out when the water collection unit 400 is drawn out. Here, the radius of the predetermined water tank center hole 410 may be equal to the distance that the water receiving unit 400 is drawn out.

The water receiving part 400 may form a water storage space 420, which is a water storage space.

The user can pull or pull out the water receiving part 400 to supply water to the water tank space 420 of the water receiving part 400. [ The water receiving part 400 is drawn out from the receiving part 500 through sliding movement and can supply water to the water tub space 420 exposed to the outside by supplying water to the user. Thereafter, when the user pushes the receiving part 400 into the receiving part 500, the receiving part 400 is brought into the receiving part 500 through the sliding movement, and the user can operate the humidifying and cleaning device. Accordingly, the user can easily supply the water to the water receiving part 400.

FIG. 10 is a perspective view showing a spraying module of a humidifying and cleaning apparatus according to an embodiment of the present invention, FIG. 11 is an exploded perspective view of a spraying module of a humidifying and cleaning apparatus according to an embodiment of the present invention, Fig. 3 is a cross-sectional view showing the spray module of the humidifying and cleaning device according to the first embodiment.

10 to 12, the injection module 800 includes a first spray housing 820 for sucking water inward, sucking the sucked water upward and ejecting the sucked water outward in a radial direction, And a housing 840.

The injection module 800 is configured to inject water stored in the water receiving part 400. Accordingly, the injection module 800 has a structure for efficiently pumping the water stored in the water receiving part 400.

The injection module 800 is rotated by receiving the rotational force of the driving unit 550, and when it rotates, it sucks the water stored in the water receiving unit 400 and can pump the water upward. The water pumped into the injection module 800 can be discharged through the injection port.

The spray module 800 may rotate the spray housings 820 and 840 to spray water.

Of course, water may be sprayed using a nozzle instead of the spraying housings 820 and 840. In this case, water can be supplied to the humidifying medium by spraying water from the row, and the rain view can be similarly implemented.

Water sprayed from the spraying housings 820 and 840 may wet the humidifying medium 350. The water sprayed from the spraying housings 820 and 840 may be sprayed toward at least one of the water receiving unit 400 and the humidifying medium 350.

Here, the water sprayed toward the water receiving part 400 may implement a rain view. The water sprayed toward the humidifying medium 350 can humidify the filtered air. In addition, it is also possible to implement a rain view by water sprayed toward the humidifying medium 350 to wet the humidifying medium, followed by water flowing to the water receiving part 400.

The spraying housings 820 and 840 may include a plurality of jetting ports 821 and 841 having different heights. In detail, the first spraying housing 820 may include a first jetting port 821. A plurality of the first injection openings 821 may be provided. The second spraying housing 840 may include a second jetting port 841. A plurality of the second ejection openings 841 may be provided.

A plurality of the second jetting openings 841 may be disposed in the circumferential direction of the second spraying housing 840. A plurality of the first jetting ports 821 may be disposed in the circumferential direction of the first spraying housing 820.

The water discharged from one jetting port forms a droplet on the inner surface of the water receiving portion 400 to implement the rain view and the water discharged from the other jetting port is wetted with the humidifying medium 350 to be used for humidification.

The first spraying housing 820 injects water toward the inner surface of the water receiving part 400 through the first jetting port 821 and the sprayed water flows downward along the inner surface of the water receiving part 400 Lt; / RTI > That is, a droplet formed in the form of water droplets is formed on the inner surface of the water receiving part 400, and the user can see the droplet through the water receiving part 400.

The second spraying housing 840 may spray water toward the humidifying medium 350 through the second jetting port 841 to wet the humidifying medium. The sprayed water flows down to the outside or the inside of the humidifying medium 350 and the flowing water can be recovered to the water receiving part 400 according to the guide of the water tank guide 700. At this time, the water recovered in the water receiving part 400 forms a droplet on the inner surface of the water receiving part 400, thereby realizing a rain view.

The injection module 800 is provided with a pumping means. The pumping means pumping the water of the water receiving portion 400 upward. The method of pumping water in the receiving part can be variously implemented. For example, water may be pumped through the amphibious pump and then injected. As another example, the injection housings 820 and 840 may be rotated and water may be pumped by friction or cross-interference with water during rotation.

In the spray module 800 of the humidifying and cleaning apparatus according to the embodiment of the present invention, a structure for pumping water through rotation of the spray housings 820 and 840 is proposed.

The first spraying housing 820 may be formed by opening the upper side and the lower side, respectively, and may further include a positive groove 810 on the inner side thereof. The lower end of the first spraying housing 820 may be spaced from the bottom of the receiving portion 500 by a predetermined distance to form a suction gap 801.

The pumping groove 810 is a pumping means for pushing water upwards through friction or mutual interference with water. The positive groove 810 may be formed on the inner surface of the first spraying housing 820.

The positive groove 810 can improve the positive water efficiency. In detail, the amphipatic groove 810 may protrude from the inner surface of the first spraying housing 820. The positive groove 810 may be formed to extend in the vertical direction. In another aspect, the positive groove 810 is disposed radially with respect to the power transmission shaft 555.

The positive groove 810 turns the horizontal rotational force against water in the vertical direction. When the positive groove 810 is formed, water can be more effectively pumped in the vertical direction. Of course, the positive groove 810 may be formed in a zigzag shape.

The upper end surface of the first spraying housing 820 may be formed wider than the lower end surface. The first spraying housing 820 may be inclined in the vertical direction. For example, the first spraying housing 820 may be in the form of a cone with a lower cross section.

The lower end of the first spraying housing 820 may be spaced apart from the bottom of the water receiving part 400 by a predetermined distance to form a suction interval 801. In detail, the suction interval 801 may be formed at a predetermined distance from the bottom of the water tank 401 and the receiving floor 501.

The water in the water receiving part 400 can be sucked into the first spraying housing 820 through the suction interval 801. [ That is, the water in the water receiving part 400 can be sucked into the injection module 800 by the suction interval 801.

The first spraying housing 820 and the second spraying housing 840 can be assembled and disassembled. The first spraying housing 820 and the second spraying housing 840 may be assembled through a screw connection.

The first spraying housing 820 may further include a thread 822 formed on the upper outer circumferential surface. The second spray housing 740 can be assembled through the thread 822.

The first spraying housing 820 may further include a first barrier 823 for limiting the movement of the second spraying housing 840 below the thread 822. [

The first barrier 823 may be formed in the circumferential direction of the first spray housing 820. For example, the first barrier 823 may be formed in a strip shape, and may protrude outward from the first spraying housing 820.

The first barrier 823 may be in close contact with the lower end of the second spray housing 840 when the first spray housing 820 and the second spray housing 840 are assembled. The first barrier 823 may protrude further outward than the thread 822.

The first spraying housing 820 may further include a first packing 825 disposed between the thread 822 and the first barrier 823.

The first packing 825 blocks water from leaking through the first spray housing 820 and the second spray housing 840. For example, the first packing 825 may be formed of an elastic material, and the first packing 825 may be formed of a ring.

The first spraying housing 820 may further include a packing mounting rib 824 disposed to fix the position of the first packing 825. The packing mounting ribs 824 may be disposed on an extension of the threads 822. In addition, the packing mounting ribs 824 may be part of the threads 822. Thus, the threads 822 may be formed in a plurality and discontinuously dispersed, and one of them may be the packing mounting ribs 824.

As described above, the first spraying port 821 may be formed in the first spraying housing 820. For example, the first jetting ports 821 may be arranged in two. The two first injection openings 821 can be formed so as to face opposite directions.

The first jetting port 821 communicates the inside and the outside of the first spraying housing 820. In this embodiment, the inner opening area of the first ejection opening 821 may be larger than the outer opening area.

The water level of the water receiving part 400 from which the injection module 800 can inject water may be higher than the suction interval and lower than the first injection port 821.

When the water level is lower than the suction interval 801, since water is not sucked, a positive number is not possible. In addition, when the water level is higher than the first jetting port 821, the water injected into the jetting port 410 is not sprayed.

The first spraying housing 820 may be formed so that the lower side thereof is opened. That is, the injection module 800 is formed so that its lower side is opened. For example, the injection module 800 may be cup-shaped. In particular, the injection module 800 may be in the shape of an inverted cup,

A housing space 847 is formed in the injection module 800. A column 510 of the receiving part 500 is positioned inside the injection module 800 and a power transmission shaft 555 is disposed inside the column 510. [ The injection module 800 may be arranged to surround the column 510. For example, the first spraying housing 820 may be disposed to surround the column 510.

The injection module 800 may be formed such that the flat section thereof is expanded toward the upper side. In addition, the column 35 may be formed so that the flat cross section thereof is reduced toward the upper side. The shape of the injection module 800 and the column 35 may be preferably a shape for effectively pumping water. Therefore, the volume of the housing space 847 can be increased toward the upper side.

When the injection module 800 is rotated, the water sucked into the inside is closely attached to the inner circumferential surface of the injection module 800 by centrifugal force. The amphibious groove 810 formed on the inner peripheral surface of the injection module 800 provides rotational force to the water sucked in.

The injection module 800 may have injection ports 821 and 841 for discharging sucked water to the outside. In the present embodiment, the injection port may be arranged to discharge water in a horizontal direction. And the water pumped through the jetting port is discharged to the outside.

As described above, the number of the injection ports 821 and 841 can be adjusted according to design conditions. For example, a plurality of the jetting ports 821 and 841 may be formed in the first spraying housing 820 and the second spraying housing 840 with a height difference.

The first jetting port 821 may be installed at a position viewed through the water receiving unit 400 and the receiving unit 500. The first jetting port 821 may be formed at a lower position than the jetting port 755 of the water tub guide 700 and the second jetting port 841 may be formed at a position higher than the jetting port 755 .

The water jetted from the second jetting port 841 is mainly used for humidifying and can be used for collecting and purifying air passing through the humidifying medium 350 incidentally. It can also be used in lane view.

After the water jetted from the first jetting port 821 hits the water receiving part 400, it is scattered to form a rainbow view. In addition, after the water jetted from the first jetting port 821 hits the water receiving portion, it may be converted into fine droplets, and the droplets may also be used in a process of collecting and purifying the air that cleans the filtered air.

On the other hand, when the injection module 800 is rotated at a speed higher than the first rotation speed, water may be injected from the first injection port 821. When the injection module 800 is rotated at a speed higher than the second rotation speed, water may be injected from the second injection port 841. The second rotation speed is higher than the first rotation speed.

That is, only when the injection module 800 is rotated at a high speed, water is discharged from the second injection port 841. The water is not discharged through the second jetting port 841 at a speed at which the jetting module 800 is normally rotated. The first injection port 821 can discharge water at every stage in which the injection module 800 is routinely operated.

As described above, if the injection module 800 is not rotated, water is not discharged through the injection ports 821 and 841. For example, when the user operates only in the air purge mode, the injection module 800 is not operated and only the blower 100 can be operated. When the user operates only in the humidification mode, the injection module 800 is rotated, and water is discharged through the injection ports 821 and 841. Of course, when the injection module 800 is operated only at the first rotational speed in the air cleaning mode, the humidifying medium 350 is not wetted, so that the air cleaning and the lane view can be performed at the same time.

Here, the user can visually confirm that water is sprayed through the water receiving part 400 and the receiving part 500. [ This water injection means that the water is being operated in the humidification mode or the air purifying mode. The user can intuitively confirm that he is operating in the humidification mode or the air cleaning mode through the spray of water.

The lower end of the injection module 800 may be disposed at a predetermined distance from the bottom of the water receiving part 400 and the receiving part 500, that is, the bottom of the water tank 401 and the receiving floor 501.

The injection module 800 may further include a spray housing cover 860 and a power transmission unit (not shown).

The power transmission unit (not shown) may be configured to transmit the rotational force of the power transmission shaft 555 to the injection module 800.

The power transmission unit may be formed on the upper side of the first spray housing 820 and connected to the first spray housing 820. The power transmitting portion may engage with the power transmitting shaft 555. Of course, the power transmitting portion may be formed below the second spray housing 820 to transmit power.

The spray housing cover 860 is positioned on the upper side of the second spray housing 860 and can engage with the power transmission shaft 555. Accordingly, the first spray housing 820 and the second spray housing 840 may be assembled with the power transmission shaft 555, and a structure for receiving the rotational force from the power transmission shaft 555 may be disposed. That is, the injection module 800 can be assembled with the power transmitting shaft 555 through the power transmitting portion and the spraying housing cover 860.

Also, unlike the present embodiment, the injection module 800 can receive rotational force in a manner other than the power transmission shaft 555. [ For example, the rotational force of the driving unit 550 can be transmitted through a belt-pulley system, a gear engagement system, a chain system, or the like.

The second spraying housing 840 is formed to be open at the upper side and the lower side, respectively, and can be assembled to the upper end of the first spraying housing 820.

The spraying housing cover 860 is coupled to the upper end of the second spraying housing 840 and covers the upper surface of the second spraying housing 840.

Of course, the first spray housing 820, the second spray housing 840, and the spray housing cover 860 can be integrally manufactured.

The outer peripheral surface of the second spray housing 840 may further include a water ring blade 850. The water ring vane 850 can flow humidifying air. That is, when the water ring housing 800 rotates, the water ring vane 850 can draw air around the water ring.

The water ring vane 850 functions not only as a function of flowing air but also as a rain view directing means for making droplets finer.

The air of the flow path 106 in which the injection module 800 is disposed flows to the most discharge side by the blowing fan of the blowing section 100 but the air around the water ring vane 850 can flow in the opposite direction . That is, the water ring vane 850 can form an air flow locally as opposed to an air flow by the blowing fan 30.

Of course, depending on the shape of the water ring vane 850, it is also possible to flow the air in the same direction as the flow by the blowing fan 30.

The air flow by the water ring vane 850 has the effect of flowing water particles around the injection module 800 to the water receiving part 400. That is, the rotation of the water ring vane 850 has an effect of generating an air flow and drawing water particles around the injection module 800.

Meanwhile, the water ring vane 850 can flow air around the injection module 800, and further can fine water jetted from the second jet opening 841. For example, the water jetted from the second jetting port 841 may collide with the water ring vane 850 and may be made fine in the form of mist.

The water jetted from the second jetting port 841 forms a predetermined trajectory, and the water ring 850 that rotates is hit with the water on the locus. In other words, among the water jetted from the second jetting port, a part of the water may be scattered by colliding with the water ring vane 850, and the rest may be diffused without colliding with the water ring vane 850.

The water dispersed in the water ring vane 850 may wet the humidifying medium 350. In addition, the water scattered in the water ring vane 850 can be formed in the water receiving part 400. In addition, the water scattered in the water ring vane 850 can be floated on the air flow path.

That is, the water finely fined by the water ring vane 850 is effective to produce a lane view.

As described above, the second spraying housing 840 may include a second jetting port 841.

The second jetting port 841 injects water toward the humidifying medium 350. For example, two of the second ejection openings 841 may be formed. And the second ejection openings 841 may be arranged to face in different directions. That is, the two second injection openings 841 are disposed so as to face each other. In another aspect, the second jetting port 841 may be disposed symmetrically with respect to the power transmission shaft 555.

The second jetting port 8411 is disposed between the watering vanes 850. The height of the second jetting port 841 may be equal to or higher than the height of the water ring vane 850. [

The part of the locus of the water jetted from the second jetting port 841 is positioned within the rotation radius of the water ring vane 850 so that when the jetting module 800 rotates, Some of the water is scattered by colliding with the water ring vane 850.

The diameters of the first jetting port 821 and the second jetting port 841 are not limited. However, as the diameter becomes smaller, small particles of water may be discharged.

On the other hand, in the case of forming two jet lines by the first jetting port and the second jetting port, since the position of the water jetting is different, the sound generated by the jetting is formed differently. This acoustic difference allows the user to visually recognize that the injection module 800 is being rotated.

The difference in sound through the plurality of jetting lines is effective for effectively conveying an operational situation to a low vision or hearing impaired person. Also, it is easy to confirm that the humidifying and cleaning device is operating even in the absence of light.

Meanwhile, the second spraying housing 840 may further include a water film-restraining rib 843 formed therein to suppress the rotation of the water film.

The water film rotation flow means a flow which is rotated along the inner peripheral surface of the injection module 800.

The water groove 810 of the first spraying housing 820 is for forming the water film rotation flow and the water film retaining rib 843 is for suppressing the water film rotation flow.

Since the water in the first spraying housing 820 must be pumped up to the second spraying housing 840, the water spraying flow is actively generated, but the water raised to the second spraying housing 840 is rotated As the flow is not formed, the injection through the second injection port 841 is easy. That is, when a high-speed water film rotation flow is formed in the second spraying housing 840, water flows along the inside without being discharged through the second jetting port.

Further, as the large amount of water stays in the second spraying housing 840, the vibration of the spraying module 800 is largely formed. Therefore, the water pumped up to the second spraying housing 840 must be rapidly injected through the second injection port 841, thereby minimizing the eccentricity of the injection module 800 and minimizing the vibration thereof.

In summary, the water-barrier ribs 843 minimize the rotational motion of the water film, thereby minimizing the eccentricity and vibration of the injection module 800.

The water-restraining ribs 843 may protrude from the inner surface of the second watering housing 840. For example, the water-barrier ribs 843 may protrude toward the power transmitting shaft 555. According to this, the water-film-restraining ribs 843 can be formed in a direction crossing the water film rotation flow. That is, the water film rotation flow flows spirally or circularly along the inner surface of the second spray housing 840, and the water film restriction ribs 843 are preferably formed in the vertical direction.

A plurality of the water-film-restraining ribs 843 may be formed.

As described above, the spraying housing cover 860 is coupled to the upper side of the second spraying housing 840 and seals the upper side of the second spraying housing 86. In one example, the spray housing cover 860 may be threadably engaged with the second spray housing 840.

The spray housing cover 860 can engage with the power transmission shaft 555. At this time, eccentricity and vibration of the injection module 800 can be more effectively reduced.

The spray housing cover 860 includes a cover body (not shown) covering an upper opening of the second spray housing 840, and a cover body 840 extending downward from the cover body, A cover mounting rib (not shown) formed on the lower side of the cover body and spaced apart from the cover body border by a predetermined distance, and a cover fixing rib (not shown) fixed to the power transmission shaft 555 (Not shown), and a reinforcing rib (not shown) connecting the shrinking portion and the packing installation rib.

The cover body borders (not shown) may include a plurality of protrusions 861 on the outer surface.

The plurality of protrusions 861 may be disposed at regular intervals of 360 degrees along the circumferential direction of the spray housing cover 860. The projection 861 can provide a gripping feeling to the user when detaching the spraying housing cover 860.

Further, the projections 861 can scatter water in a secondary direction.

The shaft fixing part is assembled with the power transmission shaft 555 and receives the rotational force from the power transmission shaft 555.

The spraying housing cover 860 may be formed larger than the diameter of the second spraying housing 840. When viewed from above, only the spray housing cover 860 is exposed, and the second spray housing 840 and the first spray housing 820 are not exposed.

13 is a cross-sectional view showing an air flow path of a humidifying and cleaning device according to an embodiment of the present invention. Hereinafter, the flow of air and the flow of water will be described with reference to FIG.

The user may supply water to the water tank space 420 of the water receiving unit 400 exposed to the outside and then push the water receiving unit 400 to the receiving unit 500. [ At this time, the receiving portion 400 may be inserted into the receiving portion 500 through the sliding movement to be fixed.

On the other hand, when the user operates only in the air cleaning mode, the injection module 800 is not operated and only the blowing fan assembly 30 is operated.

Only when the user operates in the humidification mode or operates in the clean mode and the humidification mode, the injection module 800 is rotated and water can be discharged through the injection ports 841 and 821.

The blowing fan assembly 30 operates to provide a flow pressure of air and when the injection module 800 operates, the water discharged from the injection ports 821 and 841 flows into the inside of the water receiving part 400, (Not shown).

The water discharged from the injection ports 821 and 841 is rotated while hitting the inner surface of the water receiving part 400 and the humidifying medium 350 because the injection module 800 is rotated.

The user can visually confirm that the water is sprayed through the water receiving part 400 and the receiving part 500. This water injection means that it is operating in the humidification mode. Thus, the user can intuitively confirm that the humidification mode is operating through the injection of water.

Lane view means the same effect as raining out the window. The water jetted from the jetting port can be used to produce a lane view inside the water receiving part.

That is, the effect of raining or the effect of raining is produced in the water receiving portion 400. When the lane view is rendered, droplets of various sizes are formed.

The air flow of the water ring vane 850, the first jetting port, the second jetting port, the protrusion 861 and the blowing fan assembly 30 is a rain view directing means for generating droplets.

The droplets generated by the above-described rain view directing means can flow or float in the air flow path. The droplets can secondarily humidify, collect and purge the air to be flowed, and can be formed in the form of droplets on the inner surface of the receiving portion.

On the other hand, the sprayed water is wetted with the humidifying medium 350, and then flows downward. The water flowing down from the humidifying medium 350 is guided to the water tub space 420 of the water receiving unit 400 along the upper surface of the water tub guide 700. Thereafter, the water in the water receiving part 400 is pumped back into the injection module 800 and then injected, and the above-described process is repeated.

The humidifying medium 350 is wetted with water, but is not immersed in the water tank 400. The humidifying medium 350 is not always in a wet state even if there is water stored in the water receiving unit 400 because the water stored in the water receiving unit 400 is separated from the water stored in the water receiving unit 400.

That is, the humidifying medium 350 is wetted only when operated in the humidifying mode, and the humidifying medium 350 can be maintained in a dried state when the humidifying medium 350 is operated in the air cleaning mode. Therefore, independent operation of the humidification board and the air cleaning mode can be performed.

Meanwhile, a suction force is provided by the operation of the blowing fan assembly 30, and the outside air is sucked in the filter unit 300 in all directions 360 degrees. The filtered air filtered through the filter unit 300 flows into the first flow space 901, and the process of passing through the filter unit 300 may be referred to as a first filtering process.

The filtered air flowing into the first flow space 901 passes through the humidifying medium 350 by a suction force. The filtered air is humidified by the water that is naturally evaporated in the course of passing through the humidifying medium (350). This is called humidification air.

The humidifying air passing through the humidifying medium 350 flows into the second fluid space 902, which is an internal space of the humidifying medium 350. At this time, the second flow space exists due to the strong suction force of the blowing fan assembly 30, although flow resistance due to rotation of the injection module 800 exists.

The raised humidifying air sucks the axial direction of the blowing fan assembly 30 in accordance with the guide of the flow guide 200 and can be radially discharged by the rotation of the blades. Here, the space formed by the flow guide 200 may be referred to as a third flow space 903. That is, the humidified air in the second flow space 902 flows into the third flow space 903, and is sucked into the blowing fan assembly 30.

The discharge air discharged in the radial direction of the blowing fan assembly 30 flows in the vertical direction of the upper part along the guide of the shroud 20 and the vane part 40 and finally passes through the discharge part 50 So that the humidifying air is discharged to the outside.
