Description

[0001] The present invention relates to an air cleaner having a humidifying function,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air cleaner, and more particularly, to an air cleaner which is provided with a humidifying function and a sufficient air purifying function by performing filtration of foreign matter by a filter and humidification by a swirl flow of a cyclonic system, And more particularly to a wet air cleaner constructed.

Traditionally, an air purifier has a function of purifying air using a predetermined filter or a filtering method using electricity. Basically, the humidifier generates humidification of indoor air by generating water vapor by various methods such as generation of water vapor using ultrasonic waves or heat, or natural vaporization using wind, irrespective of the air cleaning function It can be said to perform.

In recent years, various types of products having both the humidifying function and the air purifying function have been introduced in various forms, which are also called "airwashers" or "wet type air purifiers". Such an air purifier equipped with a humidification function is disclosed in Korean Patent No. 10-0863307, Japanese Patent No. 10-0805667, Registration Practical Utility Model Registration No. 20-0157935, and Korean Patent Publication No. 10-2010-0084828 It has been proposed in the form of branches.

In such an air purifier, a plurality of discs are provided on a rotating shaft disposed horizontally, and a plurality of such discs are partially rotated in a state of being immersed in water contained in a water tank. Airflow from the air blowing fan toward the disk assembly is formed so that foreign matter including dust and the like contained in the air is trapped in the water film formed on the surface of the disk and is transferred into water inside the water tank, The water on the surface of the assembly is naturally evaporated by the blowing of the blowing fan to perform a humidifying function.

However, the conventional air purifier has the following problems. In such air cleaning and humidification functions, the most important point in removing foreign substances contained in the air or spontaneously evaporating the water is the size of the contact area between the airflow and the water. However, according to the conventional air purifier, the contact area of the air flow generated in the first blowing fan is substantially limited to a part of the surface area of the disk, and the second air flow is once discharged to the outside of the air cleaner Therefore, there is a certain limit to the air purifying function and the humidifying function.

In order to sufficiently enlarge the surface area of a large number of disks provided on the rotary shaft, the interval between them must be narrow, which makes cleaning of the surface difficult. It is natural that the performance of the basic function of air cleaning is deteriorated.

Further, according to the conventional air purifier, a plurality of motors are required including a motor as a power source for rotating a rotary shaft on which a plurality of disks are mounted and a motor as a power source for rotating the air blowing fan. The necessity of at least two or more motors in this way not only increases the number of component parts but also causes a complicated assembly process. In other words, it can be pointed out that the increase in the production cost due to the increase in the number of relatively expensive components and the decrease in productivity in the assembly process can be pointed out.

Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings. First, an air purifier according to a first embodiment of the present invention will be described with reference to Figs. 1 and 2. Fig. As shown in FIGS. 1 and 2, the air purifier of the present invention has a casing 10 of a standing type having a predetermined height.

An inlet 12 through which air flows from the outside is formed on the bottom side surface of the casing 10 and an outlet 14 through which the filtered air is discharged is formed on the upper surface of the casing 10. The outside air introduced through the inlet 12 is purified by a filtering unit to be described later in the casing 10, and then the purified air is discharged through the outlet 14.

In the illustrated embodiment, the casing 10 is constituted by a casing main body 20 forming a bottom surface and side walls, and a main cover 500 for opening and closing an open upper portion of the casing main body 20. A vent hole 510 is formed in a central portion of the main cover 500. The vent hole 510 is an outlet through which purified air and humid air are discharged.

In order to purify the air introduced from outside, the casing 10 includes a first filtering unit 200 for primarily filtering the air introduced from the outside, and a second filtering unit 200 for filtering And a second filtering unit 300 for filtering the air again. The first filtering unit 200 is substantially a filtering unit for filtering foreign matter using a HEPA filter. The second filtering unit 300 may be a part for filtering the foreign matter and humidifying the air by using the cyclone principle.

 As shown more clearly in FIG. 2, the first filtering unit 200 includes a conventional filter 210, which is a HEPA filter. The cylindrical filter 210 has upper and lower portions opened, and a cylindrical portion forming a cylindrical portion forms a filter body. This filter 210 is a HEPA filter as described above, and air is filtered while passing through the filter body forming this circumferential portion. That is, it can be seen that the air is passed through the filter 210 in the course of being sucked in the radial direction from the outer circumference side of the casing 10.

 As a result, the impurities are primarily filtered by the process of passing through the filter 210. It is a matter of course that the filter 210 for the first filtering of the impurities can be selected to have a desired specification and function. It is also possible to provide an odor removing function by selectively providing a filter having a function of removing odors, for example, removing impurities.

A fan 420 is installed on the filter 210 to generate an air flow from the outside to the inside of the air purifier. The fan used in the present invention is configured to blow air from the central portion of the filter 210 radially outward of the fan 420. Therefore, it is preferable to use a centrifugal fan, and a turbo fan, a sirocco fan, or the like may be used, but it is not limited thereto. It is sufficient that the fan 420 in the present invention sucks the air outside the casing 10 to pass the filter 210 and blow air inside the filter radially outward of the fan 420. [

The fan unit 420 is rotated by a motor unit 410 that generates a rotational force by application of power. The motor unit 410 includes a rotor, a stator, and a rotating shaft 412). The rotary shaft 412 is connected to the fan 420 to rotate the fan 420 and to generate airflow. Hereinafter, the fan 420 and the motor unit 410 will collectively be referred to as a fan motor assembly 400 that generates air flow.

When the fan motor assembly 400 is operated, air flows into the casing 10 through the inlet 12 formed on the outer surface of the casing 10. It can be seen that the inflowing air passes through the filter 210, moves upward from the center of the filter 210, and then moves radially outward by the fan 420.

The air radially outwardly moved by the fan 420 ascends along the connecting passage R. The connecting passage R is a cylindrical passage formed between the casing 10 and the airflow housing 440. The connecting passage R is formed to extend from the outer portion of the fan 420 to the inside of the upper end of the casing 10. Since the fan 420 generates airflow passing through the connection passage R by rotation, air passing through the connection passage R substantially forms a swirling flow. For example, in accordance with the rotation direction of the fan 420, the air flow rising while passing through the connection passage R as viewed in a plan view is raised while rotating counterclockwise.

If the air flow passing through the connecting passage R directly contacts the casing 10, a noise problem may be caused. That is, if the air flow converted in the radial direction by the fan 420 directly impacts the casing 10, noise may be generated. Therefore, in the illustrated embodiment, the connecting passage R of the portion adjacent to the fan 420 is configured to be formed by the airflow housing 440. 3, the airflow housing 440 includes a cylindrical inner tube 442 and an outer tube 444 which are spaced apart from each other by a predetermined distance, (R) is formed between the outer pipe (442) and the outer pipe (444).

 The inner tube 442 has a diameter substantially corresponding to the upper surface of the fan motor assembly 400 and the lower end of the inner tube 442 is positioned at a portion corresponding to the upper surface of the fan motor assembly 400. The outer tube 444 is spaced apart from the inner tube 442 by a predetermined distance so that the connection tube R can be formed and the lower end of the outer tube 444 is molded so as to be in close contact with the inner diameter of the filter 310 have. Here, the outer tube 444 of the airflow housing 440 may be said to be substantially in contact with the inner surface of the casing 10.

It will be appreciated that substantially the airflow housing 440 is installed directly above the fan motor assembly 400. The motor unit 410 is accommodated in a motor cover 414 recessed upward from the bottom surface of the air flow housing 440. The fan 420 rotating by the motor unit 410 includes an air flow Is an inner region of the diameter of the inner tube 442 of the housing 400 and is supported at a position corresponding to the lower region (space). Therefore, the air flow generated by the rotation of the fan 420 is guided to the connection passage R from the inside of the outer pipe 444.

Referring again to FIG. 2, a second filtering unit 300 is provided on the upper portion of the airflow housing 440. The second filtering unit 300 filters the air that has passed through the first filtering unit 200 and generates a humidifying function. The second filtering unit 300 includes a cyclone body 310. The cyclone body 310 is for performing filtration and humidification of foreign matter by forming a swirling flow of air supplied to the inside through the above-described connection passage (R).

The cyclone body 310 is constituted by a cylindrical container having an open top, and water is supplied to the inside thereof. Here, the supply of water to the inside of the cyclone body 310 may be directly supplied by the user, or may be supplied so as to maintain a constant water level through a separate water tank.

The casing 10 is extended outside the cyclone body 310 at regular intervals, and the connecting passage R as described above is extended therebetween. Therefore, the airflow rising in the swirling flow form through the connection passage R enters the inside of the cyclone body 310 through the open top of the cyclone body 310. The open upper end of the casing 10 is configured to be opened and closed by the main cover 500.

The air flow rising in a swirling flow form along the connection passage R is introduced into the cyclone body 310 whose upper end is opened when the main cover 500 can not be lifted further by the main cover 500 will be. Since the discharge hole 510 for discharging purified air is formed in the central portion of the main cover 500, air is introduced into the cyclone body 310 from the connection passage R more efficiently So that the air inside the cyclone body 310 can be discharged more efficiently through the exhaust hole 510.

For example, the air flow rising in the swirling flow form along the connection passage R must enter the inside of the cyclone body 310 to form a swirling flow. The air circulated a plurality of times through the swirling flow in the cyclone body 310 should be discharged more smoothly through the discharge hole 510. Hereinafter, a structure for guiding the flow of air will be described.

As shown in FIGS. 2 and 4, the upper end of the casing 10 is configured to be opened and closed by the main cover 500. The main cover 500 includes a main body 502 that opens and closes an upper portion of the casing 10 and a main body 502 that is formed in a central portion of the main body 502 and forms a vent hole 510 between the main body 502 and the main body 502, And a head part 520 which is formed in a state in which the head part 520 is formed. The head 520 is formed into a circular shape when viewed from above, so that a plurality of the discharge holes 510 are formed in a circular shape.

In the main cover 500, an air guide portion 530 is formed at the bottom of the head portion 520 and integrally formed with the main body 502. The air guide portion 530 can be said to guide the airflow rising through the connection passage R into the inside of the cyclone body 310. [ Particularly, when the air flow rising through the connection passage R is guided to the inside of the cyclone body 310 without being climbed and climbed on the bottom surface of the main cover 500, Clone body < RTI ID = 0.0 > 310 < / RTI >

In order to guide the air, the air guide portion 530 has a substantially trumpet shape. By this streamlined connection curve, the air flow can be smoothly guided into the cyclone container 310 without generating vortex do. The lower end portion 532 of the air guide portion 530 preferably extends downward to have a lower position than the upper end portion 605 of the water pump 600 described later. By forming the air guide portion 530 in the shape of a trumpet tube, airflow rising through the connection passage R will be guided to the inside of the cyclone body.

Here, the above-mentioned air flow rising through the connecting passage R substantially forms a swirling flow (for example, a swirling flow in the counterclockwise direction when viewed from the top view). Therefore, it is a matter of course that the air flow flowing into the cyclone body 310 from the connection passage R also enters the swirling flow in the same manner. The swirling flow is guided by the air guide part 530. The guiding part 530 is provided with a plurality of guide ribs 530 for guiding the swirling flow into the inside of the cyclone body 310 while keeping the swirling flow in a more stable state, (See Fig. 5). The guide ribs 534 may be protruded downward along the same direction as the swirling flow so as to allow the swirling flow to flow into the inside of the cyclone body 310 while maintaining the swirling flow.

Next, the cyclone body 310 and its internal structure will be described. As described above, it can be seen that the air flowing into the inside of the cyclone body 310 is a swirling flow. It is a matter of course that such a swirling flow flows into the inside of the cyclone body 310, and a swirling flow is formed continuously in the cyclone body 310.

In the present invention, when the cyclone body 310 receives water from the outside, the water always maintains water level at least to some extent during operation. The supply of water to the cyclone body 310 can be directly supplied through the open top of the user, and can be supplied while maintaining a constant water level in a separate water tank.

The cyclone body 310, which is the main constituent of the second filtering unit 300 in the present invention, has a function of again filtering (secondary filtering) the foreign substances contained in the air supplied to the room, It is possible to say that it has a humidifying function of including moisture in air. In order to exert such a function efficiently, a water pump 600 is installed inside the cyclone body 310.

The water pump 600 performs an operation such as sprinkling or scattering the water inside the cyclone body 310 into the space inside the cyclone body 310 by rotation. That is, the water pump 600 supplies small particles of water, such as spraying or scattering, into the rotating air while forming a swirling flow inside the cyclone body 310, To be exposed.

In the present invention, the water pump 600 can be said to perform operations such as spraying water into the air from the inside of the cyclone body 310 or scattering the water. Hereinafter, the operation of the water pump 600 will be collectively referred to as " splashing water into particles into air. &Quot; The fact that the water is dispersed in the inside of the cyclone body and scattered is not limited to the particle size of the water. For example, not only the fine particle state such as mist, but also the kinetic energy It is natural that the operation of scattering the water droplet into the air by applying the water droplet is also included.

In the illustrated embodiment, the water pump 600 is configured to be rotatably supported on the bottom surface of the main cover 500. That is, the upper end of the water pump 600 is rotatably supported on the bottom surface of the main cover 500. However, it is apparent that the support structure of the water pump 600 can not be limited by these. For example, it is also possible that the lower end of the water pump 600 is simultaneously supported at the upper part of the bottom surface of the cyclone body.

Accordingly, the water pump 600 may be configured such that the upper end thereof is rotatably supported by the main cover 500. The upper end of the water pump 600 is rotatably connected to the main cover 500, Or may be rotatably supported on an upper surface of the bottom surface of the base 510. In the latter case, the bottom surface of the water pump 600 may be rotatably supported via a separate member between the lower end of the water pump 600 and the bottom surface of the cyclone body.

Next, the water pump 600 installed in the cyclone body 310 will be described. The water pump 600 in the illustrated embodiment is constructed so that water droplets or small water particles can be scattered into the inside of the cyclone body 310 after the water is drawn upward by using the centrifugal force by rotation .

4 and 5, the water pump 600 is rotatably supported by the main cover 500. As shown in FIG. A rotary shaft 630 vertically disposed by a pair of bearings 622 and 624 having a predetermined gap therebetween is rotatably supported on a bottom surface of the head portion 520 occupying a central portion of the main cover 500. [ . The bearing support block 626 supporting the bearings 622 and 624 is preferably formed of a metal material or the like so as to provide sufficient support strength. The bearing support block 626 is supported at the bottom of the head portion 52 by a bearing housing 628 that can be fixed to the bottom surface of the head portion 520.

In this manner, a rotating body 634, which rotates together with the rotating shaft, is coupled to the lower end of the rotating shaft 630 rotatably supported at the lower center of the main cover 500. The rotating body 634 is integrally formed with a plurality of bridges 616 for connection with the water pump 600 or is integrated with the bridge by bolting or screw coupling or the like. The rotating body 634 is inserted into the lower end of the bearing housing and rotatably connected to the blade supporting tube 612 of the plurality of blades 610 so as to be rotatable.

A plurality of bridges 616 extending outward from the rotating body 634 and a plurality of blades 610 are provided at a lower end of the rotating shaft 630 Which are integrally molded or separately molded, joined, and assembled, so as to rotate together.

A water pump 600 is coupled to an outer end of the bridge 616. That is, it can be seen that the water pump 600 of the present invention is rotatably supported by the rotation shaft 630 rotatably supported by the bottom surface of the center portion of the main cover 500. The water pump 600, which is rotatably supported on the bottom surface of the head portion 520 of the main cover 500, can be formed into a cylindrical or inverted conical shape. In the illustrated embodiment, the water pump 600 has an inverted conical shape .

The water pump 600, which is shaped like an inverted conical shape, is expected to be more advantageous than the cylindrical shape in terms of minimizing the occurrence of vibration during rotation. In addition, the water pump 600 is formed in an inverted conical shape, and the water can be smoothly moved upward by virtue of centrifugal force based on rotation.

The water pump 600 has an upper end opened to allow air to pass therethrough. In the illustrated embodiment, the water pump 600 has an inverted conical sidewall portion 602 and a plurality of open portions 604 formed between the sidewalls. Preferably, the open portion 604 is shaped relative to the overall height of the water pump 600.

A plurality of water guiding grooves 606 are vertically formed inside the side wall portion 602 of the water pump 600. The water guide groove 606 is for substantially pumping up the water on the bottom of the cycle body by centrifugal force when rotating. It is also possible to replace the water guide groove 606 in the illustrated embodiment with a wall (or rib) having a constant height extending in the up-and-down direction, and the concave portion between the wall and the wall And will correspond to the water guide groove 606 in the illustrated embodiment.

The water guide groove 606 may have any shape as long as it can substantially rise upward along the inside of the water guide groove 606. It is obvious that the water guide groove 606 can not be limited to a vertical groove . The open portion 604 formed between the side wall portions 602 is formed to have a constant inclination with respect to the vertical line as shown in the figure. Therefore, the uppermost portion of the water guide groove 606 is opened (opened) along the inclined open portion 604.

Since the water guide groove 606 is continuously extended upward with a predetermined distance, the outlet 608 of the water guide groove 606 is formed in the open portion 604. Further, since the open portion 604 is formed in an inclined state having a constant inclination, a plurality of openings of the water guide groove 606 are formed in the upper and lower portions of the inside of the cyclone body 30. It can be seen that the outlet 608 of the water guide groove 606 is continuously formed from the lowest part to the highest part of the open part 604.

The lower end 620 of the water pump 600 is immersed in the water contained in the cyclone body 310. The lower end portion 620 of the water pump 600 has a shape at least partially opened to allow water to enter the inside thereof. The water guide groove 606 formed on the inner surface of the water pump 600 is extended to the lower end of the water pump 600. Accordingly, when the water pump 600 rotates, the water inside the cyclone body 310 rises along the water guide groove 606 by the centrifugal force generated by the rotation. And the water rising along the water guide groove 606 will be ejected or scattered out through its outlet 608 which is molded into the open portion 604. [

At this time, since the open portion 604 is formed with a predetermined inclination with respect to the entire height or in the vertical direction, and the water guide grooves 606 are formed in a plurality of the water guide grooves 606 at regular intervals, Over the entire height of the pump 600, water will be scattered out through the open portion 604. This scattering of water can be said to mean that water is uniformly scattered over the entire height inside the cyclone body 310.

Further, if the water pump 600 is formed in the shape of a cylinder having the same or similar diameters as the upper and lower portions, vibration is more likely to occur due to rotation at the lower end portion. In this embodiment, the water pump 600 is configured as an inverted conical shape or at least partially inverted conical so as to suppress the eccentricity of the weight at the lower end as much as possible, will be.

Next, another embodiment in which the water pump 600 is rotatably supported on the bottom surface of the main cover 500 will be described. The present embodiment is an embodiment in which the water pump 600 is detachably attached to the main cover 500 by the magnetic force generated by the magnet. In the following description of the embodiment, substantially the same components as those described above will be described with the same reference numerals.

7, a pair of bearings 622 and 624, which are vertically spaced apart from each other by a pair of bearings 622 and 624, vertically arranged on the bottom surface of the head portion 520 at the center of the main cover 500, Is rotatably supported. It is a matter of course that the rotation shaft 630 has a structure that does not fall down in a downward direction. For example, a head 634 supported by a bearing 622 is formed at the upper end.

The bearing support block 626 for supporting the bearings 622 and 624 and the bearings 622 and 624 is preferably formed of metal or the like in order to provide sufficient support strength. The bearing support block 626 is supported on the bottom of the head part 520 by a bearing housing 628 for example . The bearing support block 626 may be fixed to the bottom surface of the head portion 520 by using other fastening elements or the like.

The rotation shaft 630 extends downward, and then the nut 632 is stuck at the end portion to have a constant area. A magnet housing 642 having a magnet 640 embedded therein is detachably fixed to the lower side of the nut 632 by a magnetic force. The magnet housing 642 is hooked to a water pump 600 by a plurality of (for example, three) locking hooks 644 extending downward.

Therefore, the structure for assembling the water pump 600 to the central bottom of the main cover 500 in the present embodiment is summarized, so that the rotary shaft 630 is connected to the head portion 520 through the pair of bearings 622, And is rotatably supported on the bottom surface. A magnet housing 642 incorporating a magnet 640 is detachably attached to the bottom surface of the rotary shaft 630 by magnetic force and the magnet housing 642 is detachably connected to the water pump 600.

Here, the lower end of the rotating shaft 630, which is a magnetic body, has a sufficient area through which the nut 632 reacts to the magnetic force. It is of course possible to further interpose a metal plate of a flat plate capable of covering the entire bottom surface of the nut 632. [ It is a matter of course that many other modifications are possible in the structure in which the magnet housing 642 and the water pump 600 are connected to each other so that they can be disassembled and assembled with each other.

In addition, since the water pump 600 of the present invention has an inverted conical shape, the water guide groove 606 is limited in its upper and lower areas. Therefore, as can be seen from Fig. 7, the number of the water guide grooves 606 in the upper portion 600U and the lower portion 600L of the water pump 600 is different. That is, since the lower portion 600L of the water pump 600 has a substantially small surface area, a large number of water guiding grooves can not be formed. However, if the water guide groove is formed on the basis of the lower portion 600L of the water pump 600, the water guide groove may be formed in a short distance, which may make it difficult to uniformly disperse sufficient water particles over and under the cyclone body 310 .

Therefore, in the present invention, as shown in FIG. 8, water is boiled at a predetermined height through the water guide groove 606 of the lower portion 600L, and then water is introduced into the low water groove 650 It temporarily stores water. That is, water is raised from the lower portion 600L of the water pump 600 by the rotation of the water pump 600 and temporarily stays in the low water groove 650, It means that it will become over the whole.

If the low water groove 650 is to be formed on the inner side of the water pump 600 as in the illustrated embodiment but it is difficult to form the groove in relation to the mold, the portion corresponding to the low water groove 650 It is also preferable to form the low water groove 650 as shown in the drawing by engaging a ring band 653 which is made to pass through the inside and the outside and made of synthetic resin or an elastic material such as rubber.

The water in the low water groove 650 rises along the water guide groove 606 in the upper portion 600U of the water pump 600 in accordance with the rotation. Since the water guide groove 606 on the upper part of the water pump 600 is formed in a larger number than the lower part 600L, the water scattered through the outlet 608, which is ultimately formed in the open part 604, It is expected that it will be uniformly distributed across small particles as possible.

The water pump 600 according to the present invention is most preferably formed integrally with the water pump 600 by injection molding at one time. However, when the water pump 600 can not be limited by the integral injection, It is natural that it is also possible to complete the water pump 600.

According to the present invention, the cyclone body 310 is formed of a viewable synthetic resin material, and is formed into a synthetic resin material that can be seen through the upper portion of the casing 10 where the cyclone body 310 is located. Therefore, the water scattered inside the cyclone body 310 by the rotation of the water pump 600 will be visually recognizable from the outside. That is, the air purifier according to the present invention exposes water to the inside of the cyclone body 310, and at the same time, the formation of a swirling flow is exposed to the outside. This will allow users to visually recognize the effects of air purification and humidification on the user.

According to the present invention, the air flow entering the inside of the cyclone body 310 is the swirl flow introduced through the above-described connection passage R as described above. The water pump 600 is rotated so that the water inside the cyclone body is scattered so that the air cleaner of the present invention can operate .

It goes without saying that various modifications are possible in the configuration for rotating the water pump 600 as described above. It is also possible to rotate the water pump 600 using a small motor mounted on the head 520 of the main cover 500, for example. The flow of the air that flows into the cyclone vessel 310 through the connection passage R and is discharged through the discharge hole 510 inside the cyclone vessel 310 And the water pump 600 may be rotated using the water pump 600.

Hereinafter, an embodiment in which the water pump 600 is rotated using the air flow will be described in detail. The air flow guided to the inside of the cyclone body 310 flows in a state of forming a swirling flow, and this swirling flow is formed substantially along a portion close to the inner side of the cyclone body 310. In addition, since the center hole of the main cover 500 has a circular exhaust hole 510, air circulated by the cyclone principle is discharged to the outside through the exhaust hole 510.

Since the discharge hole 510 is formed at the central portion of the cyclone body 310, a rising airflow is formed at the inner center portion of the cyclone body 310. In other words, the flow of air inside the cyclone body 310 is formed at the outer portion near the inner surface of the cyclone body 310, and at the center portion of the cyclone body 310, And the air discharged to the outside through the hole 510 forms an upward flow.

And a plurality of blades 610 formed on the outer surface of the rotating shaft 630. And is formed in such a direction as to rotate the blade supporting tube 612 in the same direction as the swirling flow formed inside the cyclone body 310 in contact with the ascending air flow. Accordingly, when the airflow rising from the center of the inside of the cyclone body 310 collides with the blade 612, the blade support tube 612 is rotated in a counterclockwise direction (as viewed in a plan view). The rotation of the blade and the blade supporting tube 612 substantially rotates the water pump 600 in the same direction through the bridge 616.

In the illustrated embodiment, the swirling flow introduced into the cyclone body 310 forms a rising air flow in the central portion of the cyclone body 310, and the rising air stream is discharged through the exhaust hole 510. Here, it is understood that the ascending air flow immediately before being discharged through the discharge hole 510 is configured to contact the blade 610 to rotate the blade supporting tube 612. The rotation of the blade 610 rotates the water pump 600 in the desired direction through the bridge 616.

In this embodiment, it can be seen that the rotation of the water pump 600 is caused by the flow of air through the outlet 12 by the fan motor assembly 400. The rotation of the water pump 400 by the air flow generated by the fan motor assembly 400 may have various advantages that do not require a separate motor for rotating the water pump 400. [ . As described above, the rotation of the water pump 400 splashes water particles by applying an external force to the water held in the cyclone body 310, as described above.

Hereinafter, the overall operation of the air purifier of the present invention having the above-described configuration will be described. The operation of the air cleaner of the present invention will now be described with reference to the overall air flow formed by the fan 420. First, when the air cleaner of the present invention is operated, the fan motor assembly 400 is driven, and the air outside the casing 10 flows into the interior of the casing 10 through the inlet 12.

Air introduced into the casing 10 from the outside (indoor) passes through the filter 210. In this process, impurities are primarily filtered. That is, the HEPA filter 210 constituting the first filtering unit 200 primarily removes impurities, and the filter 210 can be selected to have a desired specification and function. same. For example, it is possible to include not only a foreign substance such as fine dust but also a filter capable of removing odors, so that the effect of removing the odor by the filter 210 can also be expected.

In the embodiment shown in FIG. 1, the filter 210 is formed of a cylindrical filter, and the fan 420 is a centrifugal fan. However, the present invention is not limited to this configuration, Do. It is sufficient that the fan 420 forms an air flow so that the outside air can pass through the filter 210 while introducing the outside air through the inlet 12. [

The air that has passed through the filter 210 is moved in the radial direction by the fan 420, which means that the air flow flows radially toward the inner portion of the casing 10. The flow of the air generated by the fan 420 flows to the above-described connection passage R. At this time, the flow of the air flowing into the connection passage R by the rotating fan 420 forms a swirling flow , And the flow direction of such air is shown in detail in Fig.

Since the upper surface of the connecting path R is clogged by the main cover 500, the upper part of the air flow flows into the opened cyclone body 310. The air introduced into the cyclone body 310 will also maintain the swirling flow. In this process, the air guide portion 530 formed in the main cover 500 and the guide ribs 534 It is natural to receive.

In the inside of the cyclone body 310, a swirling flow is formed at the edge portion and an upward flow is formed at the central portion where the discharge hole 510 is located. In addition, as described above, air rising at the center of the cyclone body 310 applies wind pressure to the blade 610 and substantially rotates the water pump 600.

The water inside the cyclone body 310 is accumulated in the lower end portion 620 of the water pump 600. The water contained in the lower end 620 of the water pump 600 inside the cyclone body 310 is discharged to the water pump 600 by the centrifugal force, And moves upward along the water guide groove 606 formed in the side wall portion 602 of the lower end portion 620.

The water that moves along the water guide groove 606 is scattered to the outside through the plurality of outlets 608 of the water guide groove 606 formed in the open portion 604. [ The outlet of the water guide groove 606 is formed at regular intervals from the lower end portion to the upper end portion and the open portion 604 is formed with an inclination so that the water can be uniformly scattered outward as a whole.

Since the cyclone body 310 and the corresponding casing 10 are formed of a material capable of penetrating the inside of the cyclone body 310, water scattered inside the cyclone body 310 can be recognized by the user directly Will be. The fact that the state in which water is scattered can be visually confirmed means that the air purifier of the present invention is practically operative and that a sufficient humidifying effect can be recognized by the user.

In the present state, water is scattered in the cyclone body 310 while the water pump 600 rotates, and a swirling flow is being formed in the cyclone body 310 have. When the water is scattered toward the swirling flow in a state where the swirling flow is formed inside the cyclone body 310, the water particles that are scattered are exposed to the rotating air substantially repeatedly. In addition, the air circulates in the cyclone body 310 repeatedly a plurality of times and then rises at the central portion. The water particles scattered by the water pump 600 substantially repeat the water several times, .

The fact that the scattered water droplets are exposed to the swirling flow repeating at least a plurality of times substantially means that the contact surface area between the air introduced through the inlet 35 and the water droplets scattered through the water pump 600 is sufficiently secured do. The fact that the surface area of contact between the water droplets scattered and the air is wide means that the foreign matter contained in the air is substantially trapped in water by the surface tension and the suction force.

Also, the fact that the contact surface area between the water droplet to be scattered and the air is large means that the amount of water vaporized by the contact with air substantially increases. Furthermore, the contact of air with fine water particles for a sufficient time means that odor particles contained in the air can be trapped to sufficiently deodorize the air.

As described above, according to the present invention, a swirling flow is formed inside a cyclone body, and water droplets are scattered in such a swirling flow, whereby the ability to collect foreign matter (including odor particles) contained in water is excellent, As shown in FIG. That is, the cyclone body 310 constituting the second filtering unit 300 is configured such that water particles sufficiently contact with the swirling flow to collect foreign substances in the air, and at the same time, air It can be seen that it is sufficiently humidified.

If the water droplets are scattered and the swirling flow of the swirling flow is continuously repeated, the relatively heavy water particles in the cyclone body 310 sink downward as foreign matter, and the relatively light water particles are discharged into the cyclone body 310 to the interior (exterior) through the open middle central portion outlet 38. And it can be said that the discharged air can provide substantially sufficient humidification amount, and it is natural that the foreign matter is purified air sufficiently filtered.

The foreign matter collected in the water particles circulating inside the cyclone body 310 falls back to the bottom of the cyclone body 310 as described above. (For example, a UV lamp) having sterilizing function may be installed in the interior of the cyclone body 310, more preferably, at the lower end of the cyclone body 310 in order to sterilize the foreign object It will be possible. It is also expected that when molding the cyclone body or the like, it is preferable to use a material having an antibacterial function added with an antibacterial agent.

The main cover 500 is detachably detachable from the casing 10 and the cyclone body 310 is detachable from the casing 10. Thus, it becomes possible to very easily clean the cyclone body 310 which is to contain water substantially, so that the problem of air humidified by the contamination of the cyclone body can not occur.

The air in the inner center of the cyclone body 310 follows the upward flow and is discharged to the outside through the discharge hole 510 of the main cover 500. As described above, the air that ascends to be discharged in this manner acts as a driving force for rotating the water pump 600 in contact with the blade 610. By repeating such operations, air inside the cyclone body 310 The removal of the foreign matter contained in the air and the sufficient humidification of the air may proceed.

Hereinafter, another embodiment of the present invention will be described with reference to the embodiments shown in FIGS. 1 to 6 and described above.

In the embodiment illustrated and described, since the fan 420 rotates the air in a radial direction, a swirling flow is formed in the connection passage R, and the swirling flow is directly transmitted to the inside of the cyclone body 310 As shown in FIG.

However, it is sufficient that the fan 420 has a function of allowing the outside air to flow into the casing 10 and primarily to remove the foreign matter by passing the filter 210 through the process. The air flow generated in the fan 420 may be introduced into the cyclone through another passage to generate a swirling flow.

That is, when the air flow generated in the fan 420 is introduced into the inside of the cyclone body 310, air is blown into the cyclone body 310 at an eccentric position, , It is natural that the foreign matter can be removed by the same cyclone principle as described above, and that the exhausted air can be humidified by contact with the scattered water.

In the embodiment described above, the water pump is rotated by using the swirling flow inside the cyclone body. However, it is needless to say that many other modifications are possible in the configuration of rotating the water pump 600 in order to scatter the water inside the cyclone body 310. For example, it is also possible to provide a motor at the bottom of the head portion of the main cover 500, and rotate the water pump using such a motor.

In the embodiment described above, when the upper part of the cyclone body is opened and the air flow rising through the connection space R is clogged by the main cover, the inside of the cyclone body through the opened upper part of the cyclone body As shown in FIG. However, it is natural that the cyclone body is capable of various changes within the range in which the air flowing into the inside can be accepted while maintaining the swirling flow.

For example, by forming an inlet through which the swirling flow in the connection passage R can be introduced into the upper end side wall of the cyclone body, the air flow of the connection passage R forming the swirling flow can be directly introduced into the cyclone It may be configured to be introduced into the inside of the body. In this case, the upper part of the cyclone body may be configured to be opened or closed by a separate cover, or may be formed in an open state, but close to the bottom surface of the main cover 500.

In the above-described embodiment, as described above, the plurality of blades 610 rotates the water pump in response to the pressure of the airflow discharged to the discharge hole 510. [ That is, in the present invention, the blade 610 is for ultimately rotating the water pump, and it is a basic idea to use the wind generated from the fan 420 as one driving source.

Therefore, in the present invention, it can be seen that the blade 610 is provided in the water pump and is sufficient to rotate the water pump in response to the air flow. In order to rotate the water pump in response to the air flow flowing into the inside of the cyclone body 310, the side wall portion 602 is provided with a plurality of It is also possible to form it on the outer side, more preferably on the upper side into which the wind flows. Or if the water pump can be rotated in response to the air flow, its installation position can not be limited.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims. It is also obvious that it is obvious.
