전통적으로 공기청정기는 헤파(HEPA) 필터 또는 전기를 이용하는 필터링 다바이스를 이용하여 공기를 정화하는 기능을 가지고 있다. 그리고 기본적으로 가습기는, 공기 청정 기능과는 무관하게, 초음파 또는 열을 이용하여 수증기를 발생시키거나, 또는 바람을 이용하는 자연 기화 등과 같은 여러 가지 방법으로 수증기를 발생시켜 공급함으로써, 실내 공기에 대한 가습을 수행하는 것이라고 할 수 있다.Traditionally, air cleaners have the ability to purify the air using HEPA filters or filtering devices using electricity. And basically, the humidifier irrespective of the air cleaning function, humidifying the indoor air by generating water vapor using ultrasonic waves or heat, or by generating water vapor in various ways such as natural vaporization using wind. It can be said to perform.

Recently, products having both such a humidifying function and an air cleaning function have been released in various forms, and are also called 'airwashers' or 'wet air purifiers'. Air cleaners having a humidification function as described above, such as the Republic of Korea Patent No. 10-0863307, Patent No. 10-0805667, Registration Utility Model Publication No. 20-0157935, and Korea Patent Publication No. 10-2010-0084828 It has been proposed in various forms.

Such air purifiers are provided with a plurality of disks on a horizontally arranged rotary shaft, and the plurality of disks are rotating while a part of the disks is submerged in water contained in the water tank.

However, according to the conventional air cleaner, the area where the airflow in the first blower fan contacts is substantially limited to a part of the surface area of the disk, and the second airflow outside the air cleaner after contacting the surface of the disk once. Since it is discharged into the air, the air cleaning and humidification function has a certain limit. And in the conventional air cleaner or humidifier, there is no mention of a configuration capable of quiet operation by absorbing the vibration and noise generated by the motor for the rotation of the disk.

Therefore, according to the present invention, even if airflow is generated by using a fan motor assembly to purify and humidify a large amount of air, noise and vibration due to a part related to a rotating part or between airflow and a part are minimized. It can be seen that.

다음에는 도면에 도시한 실시예에 기초하면서 본 발명에 대하여 더욱 상세하게 살펴보기로 한다. 먼저 도 1 및 도 2에 기초하면서, 본 발명의 제1실시예에 의한 공기청정기에 대하여 살펴보기로 한다. 도 1 및 도 2에 도시된 바와 같이, 본 발명의 공기청정기는, 일정한 높이를 가지는 스탠딩 타입의 케이싱(10)이 외형을 형성하고 있다. Next, the present invention will be described in more detail with reference to the embodiments shown in the drawings. First, referring to FIGS. 1 and 2, an air cleaner according to a first embodiment of the present invention will be described. As shown in Fig. 1 and Fig. 2, in the air purifier of the present invention, a standing type casing 10 having a constant height forms an outer shape.
이러한 케이싱(10)의 저부 측면에는 외부에서의 공기가 유입되는 입구(12)가 성형되어 있고, 케이싱(10)의 상면에는 필터링된 공기가 배출되는 출구(14)가 성형되어 있다. 상기 입구(12)를 통하여 유입된 외부 공기는 케이싱(10)의 내부에서 후술하는 필터링부에 의하여 정화된 후, 출구(14)를 통하여 정화된 공기가 배출되도록 구성되어 있다. 이러한 케이싱(10)은 원통형상을 가지거나, 원형 단면을 가지면서 일정한 높이를 가지도록 형성된다. 이러한 형상 및 구성은 본 발명에서 사용하는 싸이클론을 형성하기 위한 것이라고 할 수 있고, 이에 대해서는 후술하기로 한다. An inlet 12 through which air from the outside flows is formed on the bottom side of the casing 10, and an outlet 14 through which filtered air is discharged is formed on an upper surface of the casing 10. After the outside air introduced through the inlet 12 is purified by the filtering unit described later inside the casing 10, the purified air is discharged through the outlet 14. The casing 10 has a cylindrical shape or is formed to have a constant height while having a circular cross section. Such a shape and configuration can be said to form a cyclone used in the present invention, which will be described later.
도 2에 도시한 바와 같이, 상기 케이싱(10)은, 저면 및 측벽을 형성하는 케이싱본체(20)와, 상기 케이싱본체(20)의 개방된 상부를 개폐하는 메인커버(500)로 구성되고 있다. 상기 메인커버(500)의 중앙부분에는 배출공(510)이 형성되는데, 이러한 배출공(510)이 정화되고 가습된 공기가 배출되는 출구라고 할 수 있다.As shown in FIG. 2, the casing 10 includes a casing body 20 that forms a bottom and sidewalls, and a main cover 500 that opens and closes an open upper portion of the casing body 20. . A discharge hole 510 is formed in the central portion of the main cover 500, and this discharge hole 510 may be referred to as an outlet through which purified and humidified air is discharged.
이와 같이 외부에서 유입된 공기의 정화를 위하여, 상기 케이싱(10)의 내부에는, 외부에서 유입된 공기를 1차로 필터링하는 제1필터링부(200)와, 상기 제1필터링부(200)에서 필터링된 공기를 다시 필터링하는 제2필터링부(300)가 구비되어 있다. 여기서 제1필터링부(200)는 실질적으로는 헤파(HEPA)필터를 이용하여 이물질을 필터링하는 부분이라고 할 수 있다. 그리고 제2필터링부(300)는 싸이클론 원리를 이용하여 이물질을 필터링하는 것과 동시에 공기를 가습시키기 위한 부분이라고 할 수 있다. In order to purify the air introduced from the outside in this way, the inside of the casing 10, the first filtering unit 200 for first filtering the air introduced from the outside, and the filtering in the first filtering unit 200 The second filtering unit 300 for filtering the air again is provided. Here, the first filtering unit 200 may be referred to as a portion for substantially filtering foreign matter using a HEPA filter. In addition, the second filtering unit 300 may be referred to as a part for filtering foreign substances and humidifying air using a cyclone principle.
여기서 제1필터링부(200)는, 헤파(HEPA) 필터로 구성되는 원통상의 필터(210)를 포함하고 있다. 이러한 원통상의 필터(210)는 상하부가 개방된 상태이고, 원통부분이 필터링의 기능을 수행하고 있다. 이러한 필터(210)는 상술한 바와 같이 헤파필터이고, 이러한 원통부분을 통과하면서 공기중의 이물질이 필터링된다.즉, 케이싱(10)의 외부에서 내부를 향하는 레디얼 방향으로 흡입되는 과정에서 상기 필터(210)를 통과하게 됨을 알 수 있다.Here, the first filtering unit 200 includes a cylindrical filter 210 composed of a HEPA filter. The cylindrical filter 210 has a top and bottom open, and the cylindrical portion performs a filtering function. The filter 210 is a HEPA filter as described above, and foreign substances in the air are filtered while passing through the cylindrical portion. That is, the filter (in the process of being sucked in the radial direction from the outside of the casing 10 to the inside) is filtered. It can be seen that the pass through 210.
그리고 이와 같이 필터(210)를 통과하는 과정에 의하여 1차적으로 불순물이 여과되는데, 이러한 불순물의 1차여과를 위한 필터(210)는 원하는 사양 및 기능을 가지는 것으로 선택할 수 있을 것임은 당연하다. 예를 들면 불순물을 제거함과 같이 악취를 제거하는 기능이 있는 필터를 선택적으로 같이 설치함으로써, 냄새 제거 기능을 부여하는 것도 가능할 것이다.  In this way, impurities are primarily filtered by the process of passing through the filter 210. The filter 210 for the primary filtration of such impurities may be selected to have a desired specification and function. For example, it may be possible to provide an odor removing function by selectively installing a filter having a function of removing odors such as removing impurities.
이와 같은 필터(210)의 상부에는, 공기청정기의 외부에서 내부로 유입되는 공기 흐름을 발생시키기 위한 팬(420)이 설치되어 있다. 본 발명에서 사용되는 팬은, 원통형 필터(210)의 중앙부분에서의 공기를 상부로 끌어올린 후 팬(420)의 방사상 외측으로 불어내는 기능을 가지는 것으로 구성된다. 따라서 이러한 팬(420)은 원심팬을 사용하는 것이 바람직하다고 할 수 있으며, 터보팬 또는 시로코팬 등이 사용될 수 있을 것이나, 이에 한정될 수 없음은 당연하다. 본 발명에서의 팬(420)은 케이싱(10) 외부에서의 공기를 흡입하여 필터(210)를 통과시키고, 필터 내부의 공기를 그 상부에 설치된 팬(420)의 방사상 외측으로 불어낼 수 있는 것으로 충분하다. In the upper portion of the filter 210, a fan 420 for generating an air flow flowing from the outside of the air cleaner to the inside is installed. The fan used in the present invention is configured to have a function of pulling air at the center portion of the cylindrical filter 210 upwardly and then blowing it radially outward of the fan 420. Therefore, such a fan 420 may be preferable to use a centrifugal fan, a turbo fan or a sirocco fan may be used, but it is not limited thereto. In the present invention, the fan 420 may suck air from the outside of the casing 10 to pass the filter 210, and blow the air inside the filter to the radially outer side of the fan 420 installed thereon. Suffice.
이러한 팬(420)은, 전원의 인가에 의하여 회전력을 발생시키는 모터부(410)에 의하여 회전하는데, 이러한 모터부(410)는 구분하여 도시하지는 않았지만 회전자와 고정자, 그리고 회전자와 연결된 회전축(412)로 구성된다. 이러한 회전축(412)은 상기 팬(420)과 연결되어 있어서, 팬(420)을 회전시키고 이에 따른 에어플로를 발생시킨다. 그리고 이하에서는 상기 팬(420) 및 모터부(410)를 총칭하여 에어플로를 발생시키는 팬모터어셈블리(400)라고 칭하기로 한다. The fan 420 is rotated by a motor unit 410 that generates a rotational force by the application of a power source. The motor unit 410 is not shown separately, but the rotor and the stator, and the rotating shaft connected to the rotor ( 412). The rotation shaft 412 is connected to the fan 420 to rotate the fan 420 and generate an airflow accordingly. Hereinafter, the fan 420 and the motor unit 410 will be collectively referred to as a fan motor assembly 400 that generates airflow.
이러한 팬모터어셈블리(400)가 동작하게 되면, 케이싱(10)의 외측면에 형성된 입구(12)를 통하여 케이싱(10)의 외부에서 케이싱(10) 내부로 공기가 유입된다. 이렇게 유입되는 공기는 필터(210)를 통과하게 되고, 필터(210)의 중앙에서 상방으로 이동한 후, 상기 팬(420)에 의하여 방사상의 외측으로 이동하게 됨을 알 수 있다.When the fan motor assembly 400 operates, air is introduced into the casing 10 from the outside of the casing 10 through the inlet 12 formed on the outer surface of the casing 10. The inflowing air is passed through the filter 210, and after moving upward from the center of the filter 210, it can be seen that the moving to the radially outward by the fan 420.
상기 팬(420)에 의하여 방사상 외측으로 이동한 공기는, 연결통로(R)를 따라 상승하게 된다. 이러한 연결통로(R)는, 케이싱(10)과 에어플로 하우징(440) 사이에서 형성되는 원통상의 통로이고, 예를 들면 일정한 높이를 가지는 링 형상의 통로라고 할 수 있다. 그리고 이러한 연결통로(R)는 상기 팬(420)의 외측 부분에서 케이싱(10)의 상단부 내측까지 연장 성형되어 있다. 상기 팬(420)은, 회전에 의하여 내부에서 외부의 연결통로(R)를 통과하는 에어플로를 발생시키게 되기 때문에, 실질적으로 상기 연결통로(R)를 향하는 공기의 흐름을 형성하게 되기때문에, 실질적으로 연결통로(R) 내부에서는 선회류가 형성된다. 예를 들면 상기 팬(420)의 회전 방향에 따라서, 평면도 상에서 볼 때 연결통로(R)를 통과하면서 상승하는 에어플로는 반시계 방향으로 회전하면서 상승하게 되는 것이다. The air moved radially outward by the fan 420 rises along the connection path (R). The connection passage R is a cylindrical passage formed between the casing 10 and the airflow housing 440, and may be, for example, a ring-shaped passage having a constant height. The connection passage R is formed to extend from the outer portion of the fan 420 to the inner side of the upper end of the casing 10. Since the fan 420 generates an air flow passing through the external connection passage R from the inside due to rotation, the fan 420 substantially forms a flow of air toward the connection passage R. As a result, the swirl flow is formed in the connection passage R. For example, according to the rotation direction of the fan 420, the airflow rising while passing through the connection passage (R) in the plan view is to rise while rotating in the counterclockwise direction.
이러한 연결통로(R)를 통과하는 에어플로가 케이싱(10)에 직접 접촉하면 소음 문제를 유발할 수 있다. 즉, 상기 팬(420)에 의하여 레디얼 방향으로 전환된 에어플로가 직접 케이싱(10)에 충격을 가하게 되면 소음이 발생할 수 있다. 특히 팬(420)에 의하여 방향이 전환된 에어플로가 케이싱(10) 내측부분에 접촉하는 부분에서는, 소음 및 진동이 더욱 크게 나타날 수 있을 것으로 예상된다. If the airflow passing through the connection passage (R) is in direct contact with the casing 10 may cause noise problems. That is, when the airflow converted to the radial direction by the fan 420 directly impacts the casing 10, noise may occur. In particular, it is expected that the noise and vibration may appear even more in the part where the airflow turned by the fan 420 contacts the inner part of the casing 10.
따라서 상기 팬(420)과 인접한 부분의 연결통로(R)에서 소음 및 진동의 발생을 최대한 억제할 수 있도록 구성하는 것이 요구된다. 본 발명에서는, 에어플로가 통과하는 원통(링) 형상의 연결통로(R)가 에어플로하우징(440)에 의하여 형성될 수 있도록 구성하고 있다. 도 3을 참조하면 알 수 있는 바와 같이, 에어플로하우징(440)은, 서로 일정한 간격을 가지는 원통형의 내부관(442)과 외부관(444)으로 구성되고 있으며, 이러한 내부관(442)과 외부관(444) 사이에서 연결통로(R)가 형성되고 있다.Therefore, it is required to be configured to suppress the generation of noise and vibration in the connection passage (R) of the portion adjacent to the fan 420 as much as possible. In the present invention, the connecting passage (R) of the cylindrical (ring) shape through which the air flow passes is configured to be formed by the air flow housing 440. As can be seen with reference to Figure 3, the air flow housing 440 is composed of a cylindrical inner tube 442 and the outer tube 444 having a predetermined interval from each other, such an inner tube 442 and the outer A connecting passage R is formed between the pipes 444.
그리고 상기 내부관(442)은 팬모터어셈블리(400)의 상부에 해당하는 지름을 가지고 있어서, 실질적으로 내부관(442)의 저면에 팬모터어셈블리(400)가 설치되는 것이라고 할 수 있다. 또한 외부관(444)은 케이싱(10)의 내측면에 설치되는 것이라고 할 수 있고, 외부관(444)은 내부관(442)과의 사이에서 일정한 간격을 가짐으로써, 연결통로(R)가 형성될 수 있도록 하고 있음을 알 수 있다.  In addition, since the inner tube 442 has a diameter corresponding to an upper portion of the fan motor assembly 400, it may be said that the fan motor assembly 400 is installed on the bottom surface of the inner tube 442. In addition, the outer tube 444 may be said to be installed on the inner surface of the casing 10, the outer tube 444 has a constant distance between the inner tube 442, the connection passage (R) is formed It can be seen that it is possible to be.
이러한 외부관(444)의 하부는 기본적으로 팬모터어셈블리(400)의 외측에 대응하는 위치까지 하부로 연장되도록 성형된다. 그리고 외부관(444)의 하단부는, 도시한 실시예에서와 같이, 상기 필터(310)의 내경에 밀착되도록 내측으로 경사를 가지고 연장 성형되어 있다. 이와 같은 구성에 의하면, 상기 팬모터어셈블리(400)에서 발생하는 에어플로는 내부관(442)과 외부관(444) 사이에 진행하게 되는데, 여기서 팬(420)이 회전하고 있기 때문에, 내부관(442)과 외부관(444) 사이에서는 선회류가 생성된다. 내부관(442)과 외부관(444) 사이에서 선회류가 생성된다는 것은 실질적으로 연결통로(R) 내부에서 선회류가 생성되면서 공기가 상승한다는 것을 의미하는 것이다. The lower portion of the outer tube 444 is basically formed to extend downward to a position corresponding to the outside of the fan motor assembly 400. And the lower end of the outer tube 444, as shown in the illustrated embodiment, is elongated inwardly inclined in close contact with the inner diameter of the filter 310. According to such a configuration, the air flow generated in the fan motor assembly 400 proceeds between the inner tube 442 and the outer tube 444. Here, since the fan 420 is rotating, the inner tube ( A swirl flow is created between 442 and the outer tube 444. The fact that the swirl flow is generated between the inner tube 442 and the outer tube 444 substantially means that the air rises while the swirl flow is generated in the connection passage R.
그리고 상기 에어플로하우징(440)은, 팬모터어셈블리(400)의 직상부에 설치된다. 상기 모터부(410)는 에어플로하우징(440)의 저면에서 상방으로 오목하게 성형된 모터커버(414)에 수납되어 있으며, 상기 모터부(410)에 의하여 회전하는 팬(420)은 에어플로하우징(400)의 내부관(442)의 지름의 내부영역임과 동시에 그 하부 영역(공간)에 해당하는 위치에서 지지되고 있다. 따라서 상기 팬(420)의 회전에 의하여 발생하는 에어플로는, 외부관(444)의 내부에서 연결통로(R)로 유도되는 것이다.The air flow housing 440 is installed directly above the fan motor assembly 400. The motor unit 410 is accommodated in the motor cover 414 formed concave upward from the bottom of the air flow housing 440, the fan 420 rotated by the motor unit 410 is air flow housing It is an inner region of the diameter of the inner tube 442 of the 400 and is supported at a position corresponding to its lower region (space). Therefore, the air flow generated by the rotation of the fan 420 is guided to the connection passage (R) inside the outer tube (444).
이상에서 알 수 있는 바와 같이, 본 발명의 연결통로(R)는, 내부관(442)과 외부관(444) 사이에서 형성되고 있다. 이와 같은 구성에 의하면, 상기 팬모터어셈블리(400)에서 발생하는 에어플로는 내부관(442)과 외부관(444) 사이에서 흐르게 되는데, 여기서 팬모터어셈블리(400)에서 발생하는 에어플로가 접촉하여 충격이 가장 크게 작용하는 것은 실질적으로 외부관(444)이라고 할 수 있다. As can be seen from the above, the connecting passage R of the present invention is formed between the inner tube 442 and the outer tube 444. According to this configuration, the air flow generated in the fan motor assembly 400 flows between the inner tube 442 and the outer tube 444, where the air flow generated in the fan motor assembly 400 is in contact with each other. It can be said that the outermost impact 444 is the greatest impact.
여기서 실질적으로 외부관(444)은 케이싱(10)의 내측에 형성되고 있는 것이기 때문에, 공기청정기의 외관을 형성하고 있는 케이싱(10)에 직접 에어플로가 접촉하는 것에 비하여, 소음 및 진동이 저감될 수 있음은 당연하다고 할 수 있다. 즉, 본 발명에 의한 에어플로하우징(440)은 선회류가 형성되는 연결통로(R)을 형성하면서, 팬모터어셈블리(400)가 발생시키는 에어플로에 의한 소음 및 진동을 일차적으로 흡수함으로써, 최소화시키는 1차적인 기능을 가지고 있다고 할 수 있다. Since the outer tube 444 is formed inside the casing 10 substantially, the airflow directly contacts the casing 10 forming the appearance of the air cleaner, so that noise and vibration can be reduced. Of course it can be said. That is, the airflow housing 440 according to the present invention forms a connection passage R through which the swirl flow is formed, and minimizes the noise and vibration caused by the airflow generated by the fan motor assembly 400. It can be said that it has a primary function.
도 3의 확대도에서 알 수 있는 바와 같이, 상기 외부관(444)과 케이싱(10) 사이에는, 진동흡수부재(DR)이 개재되어 있다. 상기 진동흡수부재(DR)는 에어플로하우징(440)의 외부관(444)을 감싸는 원뿔 또는 원통 형상으로 성형되어, 기본적으로 외부관(444)에서 케이싱(10)으로 전달되는 진동을 최대한 흡수함으로써 소음의 전달도 방지할 수 있도록 설치되는 것이다. As can be seen in the enlarged view of FIG. 3, a vibration absorbing member DR is interposed between the outer tube 444 and the casing 10. The vibration absorbing member DR is formed into a conical or cylindrical shape surrounding the outer tube 444 of the airflow housing 440, thereby basically absorbing the vibration transmitted from the outer tube 444 to the casing 10 as much as possible. It is installed to prevent the transmission of noise.
이러한 진동흡수부재(DR)은, 예를 들면 EPDM을 포함하는 고무로 성형되거나, 압축된 스폰지, 고무 또는 실리콘이 첨가된 물질(합성수지), 또는 폼(Foam) 등으로 성형되어, 진동을 흡수할 수 있고 이러한 진동의 흡수에 의하여 소음의 전달도 저감시킬 수 있는 것으로 성형될 수 있다. 여기서 예시한 재질 이외에도 진동을 흡수할 수 있거나 소음을 흡수하여 외부로 전달되는 것을 방지할 수 있는 것이면 어떠한 재질로 가능할 것임은 당연하고, 예를 들면 부직포 등과 같은 인공 또는 천연 섬유재로 성형하는 것도 가능할 것이다. The vibration absorbing member DR may be formed of, for example, a rubber including EPDM, or may be molded of a compressed sponge, rubber or silicone-added material (synthetic resin), foam, or the like to absorb vibration. It can be molded to be able to reduce the transmission of noise by the absorption of such vibration. In addition to the materials exemplified herein, any material can be used as long as it can absorb vibration or prevent noise from being transmitted to the outside. Naturally, it can be formed from artificial or natural fiber materials such as nonwoven fabrics. will be.
따라서 팬모터어셈블리(400)에 의하여 발생하는 에어플로가 상술한 외부관(444)에 접촉함으로써 발생하는 진동 및 소음은, 진동흡수부재(DR)에 의하여 실질적으로 현저하게 저감될 수 있을 것임은 당연하다고 할 수 있다. 다음에는 본 발명의 공기청정기에서 회전에 의하여 진동 또는 소음이 발생할 수 있는 다른 부분에 대하여 살펴보기로 한다. Therefore, the vibration and noise generated by the air flow generated by the fan motor assembly 400 in contact with the outer tube 444 described above will be substantially reduced by the vibration absorbing member DR. It can be said. Next, the air cleaner of the present invention will be described with respect to other parts in which vibration or noise may occur due to rotation.
상술한 모터부(410)는 전기의 인가에 의하여 회전축(412)을 회전시킴으로써, 상기 회전축(412)에 지지되는 팬(420)을 회전시키게 된다. 여기서 합성수지재로 만들어지는 팬(420)은 회전 시 다양한 원인에 의하여 진동 및 소음이 발생할 수 있음은 주지의 사실이다. 가장 큰 하나의 원인을 들면, 팬(420)은 전체적으로 질량이 균일하게 분포되어야 회전 시 편심에 의한 진동 및 소음의 발생이 방지될 수 있으나, 실제 성형 시에는 이렇게 만드는 것은 현실적으로 어렵다. The motor unit 410 rotates the rotating shaft 412 by the application of electricity, thereby rotating the fan 420 supported by the rotating shaft 412. It is well known that the fan 420 made of a synthetic resin material may cause vibration and noise due to various causes during rotation. For one of the biggest causes, the fan 420 should be uniformly distributed throughout the mass to prevent the generation of vibration and noise due to eccentricity when rotating, but in actual molding it is difficult to make this.
따라서 본 발명에서는, 상기 회전축(412)과 팬(420)을 댐퍼(418)를 통하여 연결함으로써, 회전에 의하여 팬(420)에서 발생하는 진동 및 소름이 상기 댐퍼(418)에서 흡수될 수 있도록 구성하고 있다. 기본적으로 상기 댐퍼(418)는, 회전축(412)과 연결되는 부분은 알미늄과 같은 금속으로, 그리고 팬(420)과 연결되는 부분도 금속으로 성형하고, 중간 부분에 진동을 흡수할 수 있는 고무 재질의 댐핑부분을 개재한 것이라고 할 수 있다. 따라서 팬(420)의 질량 편심 등을 포함하여 여러 가지 이유로 발생하는 진동은 상술한 댐핑부분에서 흡수할 수 있게 된다. 여기서 팬(420)에서 발생하는 진동이라고 함은, 회전 시 진원을 이루지 못하는 어떠한 것에서 오는 것을 모든 비정상적인 움직임을 포함하는 것이라고 할 수 있다.Therefore, in the present invention, by connecting the rotary shaft 412 and the fan 420 through the damper 418, the vibration and creepy generated from the fan 420 by the rotation can be absorbed in the damper 418 Doing. Basically, the damper 418, a part connected to the rotating shaft 412 is made of a metal such as aluminum, and a part connected to the fan 420 is also formed of a metal, a rubber material that can absorb vibration in the middle portion It can be said through the damping part of. Therefore, the vibration generated by various reasons including the eccentric mass of the fan 420 can be absorbed by the damping portion described above. Here, the vibration generated in the fan 420 may include all abnormal movements that come from something that does not form a circle during rotation.
그리고 상기 연결통로(R)는, 도 2를 참조하면 알 수 있는 바와 같이, 제2필터링부(300)와 연결되어 있다. 이러한 제2필터링부(300)는, 제1필터링부(200)를 통과한 공기를 다시 필터링(2차 필터링)함과 동시에, 가습 기능을 발생시키는 부분이라고 할 수 있다. 이러한 제2필터링부(300)는 싸이클론바디(310)를 포함하여 구성되고 있다. 싸이클론바디(310)는, 상술한 연결통로(R)를 통하여 내부로 공급되는 공기가 선회류를 형성함으로써, 이물질의 여과 및 가습을 수행하기 위한 것이다. The connection passage R is connected to the second filtering unit 300, as can be seen with reference to FIG. 2. The second filtering unit 300 may be referred to as a part for filtering (secondary filtering) the air passing through the first filtering unit 200 and generating a humidification function. The second filtering unit 300 is configured to include a cyclone body (310). The cyclone body 310 is for performing filtration and humidification of foreign matter by forming a swirl flow of the air supplied to the inside through the above-described connection passage (R).
이러한 싸이클론바디(310)는, 상부가 열린 원통형의 용기로 구성되고, 그 내부에는 물이 공급되어 있는 상태이다. 여기서 사이클론바디(310) 내부로의 물의 공급은 사용자가 직접 공급하는 것도 가능하고, 별도의 물탱크를 통하여 일정한 수위를 유지할 수 있도록 공급되도록 하는 것도 가능하다. The cyclone body 310 is composed of a cylindrical container with an open top, and water is supplied therein. Here, the supply of water into the cyclone body 310 may be directly supplied by the user, or may be supplied to maintain a constant water level through a separate water tank.
상기 연결통로(R)를 통하여 선회류 형태로 상승하는 에어플로는, 싸이클론바디(310)의 열린 상부를 통하여 싸이클론바디(310)의 내부로 들어가게 된다. 여기서 케이싱(10)의 열린 상단부는 메인커버(500)에 의하여 개폐될 수 있도록 구성되고 있다. 상기 연결통로(R)를 따라 선회류 형태로 상승하는 에어플로는, 상기 메인커버(500)에 의하여 더 이상 상승하지 못하는 상태가 되면, 상단부가 열려 있는 싸이클론바디(310)의 내부로 들어가게 될 것이다. 여기서 상기 메인커버(500)의 중앙 부분에는 정화된 공기를 배출하는 배출공(510)이 성형되어 있기 때문에, 연결통로(R)에서 싸이클론바디(310)의 내부로 공기를 보다 효율적으로 유입시킴과 동시에 싸이클론바디(310) 내부의 공기가 배출공(510)을 통하여 보다 효율적으로 배출될 수 있도록 구분하는 구조가 필요하다. The airflow rising in the swirl flow form through the connection passage R enters into the cyclone body 310 through the open upper portion of the cyclone body 310. Here, the open upper end of the casing 10 is configured to be opened and closed by the main cover 500. The airflow rising in the form of swirl flow along the connection passage (R), when the state can no longer rise by the main cover 500, the upper end is to enter the cyclone body 310 is open. will be. Here, since the discharge hole 510 for discharging the purified air is formed in the central portion of the main cover 500, the air flows more efficiently into the cyclone body 310 from the connection passage R. At the same time, there is a need for a structure that separates the air inside the cyclone body 310 to be discharged more efficiently through the discharge hole 510.
예를 들어, 연결통로(R)를 따라 선회류 형태로 상승한 에어플로는, 싸이클론바디(310)의 내부로 들어가면서 선회류를 형성해야 한다. 그리고 사이클론 바디(310) 내부에서 선회류로 만들어져서 여러 번 선회한 공기는 상기 배출공(510)을 통하여 보다 원활하게 배출되어야 할 것이다. 이와 같은 공기의 흐름을 안내하기 위한 구조에 대하여 살펴보기로 한다. For example, the airflow rising in the form of swirl flow along the connection passage R should form swirl flow as it enters the cyclone body 310. In addition, air that is made of swirling flow in the cyclone body 310 and rotated several times should be discharged more smoothly through the discharge hole 510. A structure for guiding such a flow of air will be described.
도 2 및 도 4에 도시한 바와 같이, 상기 케이싱(10)의 상단부는 메인커버(500)에 의하여 개폐될 수 있도록 구성되고 있다. 상기 메인커버(500)는, 상기 케이싱(10)의 상부를 개폐하는 본체(502)와, 상기 본체의 중앙 부분에 성형되고, 본체(502)와의 사이에서 배출공(510)을 성형하면서 일부 이격된 상태로 성형되는 헤드부(520)으로 구성되고 있다. 이러한 헤드부(520)는 평면도 상에서 볼 때 원형으로 성형되고 있으며, 따라서 배출공(510)도 다수 개가 원형으로 배열되도록 성형되어 있다. 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 is formed in the central portion of the main body 502, which opens and closes the upper portion of the casing 10, and is partially separated while forming the discharge hole 510 between the main body 502 and the main cover 502. It is comprised by the head part 520 shape | molded in the state which was made. The head portion 520 is formed in a circular shape when viewed in plan view, and thus, a plurality of discharge holes 510 are also formed to be arranged in a circular shape.
그리고 상기 메인커버(500)에서, 상기 헤드부(520)의 외측임과 동시에 저면 부분에는, 상기 본체(502)와 일체로 성형되는 에어가이드부(530)가 구비되어 있다. 이러한 에어가이드부(530)는, 상술한 연결통로(R)를 통하여 상승하는 에어플로를 싸이클론바디(310)의 내부로 안내하기 위한 것이라고 할 수 있다. 특히 상기 에어가이드부(530)는 연결통로(R)를 통하여 상승하는 에어플로가, 메인커버(500)의 저면에 막혀서 더 이상 상승하지 못하고 싸이클론바디(310)의 내측으로 유도될 때, 싸이클론바디(310)의 측벽을 따라 흐를 수 있도록 안내한다.In the main cover 500, an air guide part 530 integrally formed with the main body 502 is provided at the same time as the outside of the head part 520 and at the bottom of the main cover 500. The air guide part 530 may be said to guide the airflow rising through the connection passage R to the inside of the cyclone body 310. Particularly, the air guide part 530 is a cyclone when the airflow rising through the connecting passage R is blocked by the bottom of the main cover 500 and is no longer raised and is guided to the inside of the cyclone body 310. It guides to flow along the sidewall of the clone body (310).
이와 같은 공기의 안내를 위하여, 에어가이드부(530)는 실질적으로 나팔관 형상을 가지고 있고 이러한 유선형 연결곡선에 의하여, 에어플로가 와류의 발생 없이 부드럽게 싸이클론용기(310)의 내부로 안내할 수 있게 된다. 그리고 에어가이드부(530)의 하단부(532)는 후술하는 워터펌프(600)의 상단부(605) 보다 낮은 위치를 가지도록 하방으로 연장되는 것이 바람직하다. 이와 같이 상기 에어가이드부(530)를 나팔관 형상으로 성형함으로써, 연결통로(R)를 통하여 상승하는 에어플로는 싸이클론바디의 내측으로 안내될 것이다. In order to guide the air, the air guide part 530 has a substantially fallopian tube shape, and by this streamlined connection curve, the airflow can be guided smoothly into the cyclone container 310 without vortex generation. do. The lower end portion 532 of the air guide portion 530 is preferably extended downward to have a lower position than the upper end portion 605 of the water pump 600 to be described later. As such, by forming the air guide portion 530 in the shape of a fallopian tube, the airflow rising through the connection passage R will be guided into the cyclone body.
여기서 상기 연결통로(R)를 통하여 상승하는 에어플로는, 실질적으로 선회류(예를 들면 평면도 상에서 볼 때 반시계 방향의 선회류)를 형성하고 있음은 상술한 바와 같다. 따라서 연결통로(R)에서 싸이클론바디(310)의 내부로 유입되는 에어플로도 동일하게 선회류를 이루면서 들어가게 되는 것은 당연하다. 여기서 이러한 선회류는 상기 에어가이드부(530)에 의하여 가이드되는데, 상기 가이드부(530)에는 이러한 선회류를 더욱 안정된 상태로 유지하면서 싸이클론바디(310)의 내부로 안내하기 위한 다수개의 안내리브(534)가 저면에 성형되어 있다(도 5 참조). 이러한 안내리브(534)는, 선회류가 그대로 유지되면서 싸이클론바디(310)의 내부로 유입되도록 하기 위하여, 선회류와 동일한 방향을 따라 하방으로 일정한 두께로 돌출 성형되는 것이라고 할 수 있다. Here, the airflow rising through the connection passage R substantially forms a swirl flow (for example, a counterclockwise swirl flow in plan view), as described above. Therefore, it is natural that the airflow flowing into the cyclone body 310 from the connection passage R enters while forming the same swirl flow. Here, the swirl flow is guided by the air guide portion 530, the guide portion 530, a plurality of guide ribs for guiding the inside of the cyclone body 310 while maintaining this swirl flow in a more stable state 534 is molded at the bottom (see FIG. 5). The guide ribs 534 may be formed to protrude to a predetermined thickness downward in the same direction as the swirl flow in order to allow the swirl flow to flow into the cyclone body 310.
다음에는 싸이클론바디(310) 및 그 내부 구성에 대하여 살펴보기로 한다. 상술한 바와 같이, 싸이클론바디(310)의 내부로 유입되는 공기는 선회류임을 알 수 있다. 그리고 이러한 선회류가 싸이클론바디(310)의 내부로 유입되어, 사이클론바디(310) 내에서도 계속하여 선회류가 형성되고 있음은 당연하다. Next, the cyclone body 310 and its internal configuration will be described. As described above, it can be seen that the air flowing into the cyclone body 310 is a swirl flow. And it is natural that the swirl flow is introduced into the cyclone body 310, the swirl flow is continuously formed even in the cyclone body (310).
본 발명에서 싸이클론바디(310)는, 외부에서 물을 공급받아서 동작 시 항상 물이 어느 정도 이상의 수위를 유지하고 있다. 그리고 싸이클론 바디(310)로의 물의 공급은, 사용자가 개방된 상부를 통하여 직접 공급하는 것도 가능하고, 별도의 물탱크에서 일정한 수위를 유지하면서 공급될 수 있도록 하는 것도 가능할 것임은 상술한 바와 같다.In the present invention, the cyclone body 310, the water is supplied from the outside at all times when the water maintains a certain level or more. In addition, the supply of water to the cyclone body 310 may be directly supplied by the user through an open upper portion, and may be possible to be supplied while maintaining a constant water level in a separate water tank.
본 발명에서 제2필터링부(300)의 주요 구성이라고 할 수 있는 싸이클론바디(310)는, 실내로 공급하는 공기에 포함된 이물질을 다시 한번 필터링(2차필터링)하는 기능과, 실내로 공급하는 공기에 수분을 포함시키는 가습 기능을 동시에 가지는 것이라고 할 수 있다. 이러한 기능을 효율적으로 발휘하기 위하여, 상기 싸이클론바디(310)의 내부에는 워터펌프(600)가 설치되어 있다. Cyclone body 310, which can be said to be the main configuration of the second filtering unit 300 in the present invention, the function of filtering (secondary filtering) the foreign matter contained in the air supplied to the room once again, and supplies to the room It can be said that it has a humidification function which includes water to air at the same time. In order to efficiently exhibit such a function, the water pump 600 is installed inside the cyclone body 310.
이러한 워터펌프(600)는, 회전에 의하여, 싸이클론바디(310)의 내부에 있는 물을 싸이클론바디(310) 내부의 공간에 뿌리거나 비산시키는 등의 동작을 수행하는 것이다. 즉, 워터펌프(600)는, 싸이클론바디(310)의 내부에서 선회류를 형성하면서 회전하고 있는 공기 중으로, 뿌리거나 비산시키는 등과 같이 물을 작은 입자화하여 공급함으로써, 물입자가 선회류 중에 노출되도록 하는 것이다. The water pump 600, by rotation, to perform the operation, such as spraying or scattering water in the interior of the cyclone body 310 to the interior of the cyclone body (310). That is, the water pump 600 is supplied to the air rotating while forming the swirl flow inside the cyclone body 310 by supplying small particles of water, such as spraying or scattering, so that the water particles are in the swirl flow. To be exposed.
본 발명에서, 상기 워터펌프(600)는, 물을 입자화하여 싸이클론바디(310)의 내부에서 공기 중으로 뿌리거나 비산시키는 등의 동작을 수행하는 것이라고 할 수 있는데. 이러한 워터펌프(600)의 동작을 총칭하여 물을 입자화하여 공기중으로 비산시킨다는 용어로 정의하기로 한다. 여기서 싸이클론 바디의 내부에서 물을 입자화하여 비산시킨다는 것은, 물의 입자 크기로 한정할 수 없는 것으로, 예를 들면 미스트와 같은 미세 입자 상태는 물론이고, 싸이클론 내부에 고인 물에 운동에너지(외력)를 가하는 등에 의하여 물방울이 공기 중으로 비산되는 등의 동작도 포함되는 것은 당연하다. In the present invention, the water pump 600, it can be said to perform an operation such as spraying or splashing into the air in the interior of the cyclone body 310 by granulating the water. The operation of the water pump 600 will be collectively defined as a term of granulating water and scattering it into the air. Here, the granulation and scattering of water in the cyclone body is not limited to the particle size of the water. For example, fine particles such as mist, as well as kinetic energy (external force) Naturally, the water droplets are also scattered in the air by adding a).
도시한 실시예에 있어서, 상기 워터펌프(600)는 메인커버(500)의 저면에 회전 가능하게 지지되도록 구성되고 있다. 즉, 워터펌프(600)의 상단부가 메인커버(500)의 저면에 회전 가능하게 지지되고 있다. 그러나 워터펌프(600)의 지지구조는 이러한 것에 의하여 한정될 수 없음은 자명하다. 예를 들면 상기 워터펌프(600)의 하단부가 싸이클론바디의 저면 상부에서 동시에 지지되도록 구성하는 것도 가능할 것이다. In the illustrated embodiment, the water pump 600 is configured to be rotatably supported on the bottom of the main cover 500. That is, the upper end of the water pump 600 is rotatably supported on the bottom of the main cover 500. However, it is apparent that the support structure of the water pump 600 can not be limited by this. For example, the lower end of the water pump 600 may be configured to be simultaneously supported on the upper surface of the cyclone body.
따라서 상기 워터펌프(600)는, 그 상단부가 메인커버(500)에 의하여 회전 가능하게 지지되도록 구성되는 것도 가능하고, 메인커버(500)에 상단부가 연결되어 회전 가능하게 지지되고 하단부가 싸이클론바디(510)의 저면 상부에 회전 가능하게 지지되도록 구성하는 것도 가능하다. 후자의 경우, 워터펌프(600)의 하단부와 싸이클론바디의 저면과의 사이에 별도의 부재를 개재하여 워터펌프(600)의 저면이 회전 가능하게 지지되도록 구성하는 것도 가능할 것이다. Accordingly, the water pump 600 may be configured such that its upper end is rotatably supported by the main cover 500, and the upper end is connected to the main cover 500 to be rotatably supported, and the lower end is a cyclone body. It is also possible to be configured to be rotatably supported on the upper surface of the bottom (510). In the latter case, the bottom of the water pump 600 may be rotatably supported through a separate member between the lower end of the water pump 600 and the bottom of the cyclone body.
다음에는 상기 싸이클론바디(310) 내부에 설치되어 회전하는 워터펌프(600)에 대하여 살펴보기로 한다. 도시한 실시예에서의 워터펌프(600)는 회전에 의한 원심력을 이용하여, 물을 상방으로 끌어올린 후, 싸이클론바디(310)의 내부로 물방울 또는 작은 물입자를 비산시킬 수 있도록 구성되고 있다. Next, the water pump 600 installed inside the cyclone body 310 will be described. In the illustrated embodiment, the water pump 600 is configured to lift water upward by using a centrifugal force by rotation, and then to cause droplets or small water particles to scatter into the cyclone body 310. .
도 4 및 도 5를 참고하면 알 수 있는 바와 같이, 상기 워터펌프(600)는, 메인커버(500)에 회전 가능하게 지지되고 있다. 상기 메인커버(500)의 중앙부분을 차지하고 있는 헤드부(520)의 저면에는, 상하에서 일정한 간격을 가지고 있는 한 쌍의 베어링(622,624)에 의하여 수직으로 배치되는 회전축(630)이 회전 가능하게 지지되고 있다. 상기 베어링(622,624)을 지지하고 있는 베어링지지블럭(626)은 금속재 등으로 성형되는 것이 충분한 지지강도를 제공하기 위하여 바람직하다고 할 수 있다. 그리고 상기 베어링지지블럭(626)은, 헤드부(520)의 저면에 고정될 수 있는 베어링하우징(628)에 의하여 헤드부(52)의 저부에 지지되고 있음을 알 수 있다. As can be seen with reference to FIGS. 4 and 5, the water pump 600 is rotatably supported by the main cover 500. On the bottom surface of the head portion 520 occupying the center portion of the main cover 500, a rotation shaft 630 vertically disposed by a pair of bearings 622 and 624 having a predetermined interval from the top and bottom is rotatably supported. It is becoming. The bearing support block 626 supporting the bearings 622 and 624 may be preferable to be formed of a metal material to provide sufficient support strength. The bearing support block 626 may be supported by the bearing housing 628, which may be fixed to the bottom of the head 520, at the bottom of the head 52.
이와 같은 구성에 의하여, 메인커버(500)의 중심 하부에서 회전 가능하게 지지되는 회전축(630)의 하단부에는 회전축과 같이 회전하는 회전체(634)가 결합되어 있다. 그리고 상기 회전체(634)는, 워터펌프(600)와의 연결을 위한 다수의 브릿지(616)와 일체로 성형되거나 볼팅 또는 스크류결합 등에 의하여 브릿지와 일체화되어 있다. 또한 상기 회전체(634)는, 베어링하우징의 하단부에 삽입되어 회전 가능한 상태이고 다수의 블레이드(610)가 구비하는 블레이드지지관(612)와도 연결되어 같이 회전할 수 있도록 설치되어 있다. By such a configuration, the lower end of the rotating shaft 630 which is rotatably supported at the lower center of the main cover 500 is coupled to the rotating body 634 to rotate like a rotating shaft. The rotating body 634 is integrally formed with a plurality of bridges 616 for connection with the water pump 600 or integrated with the bridge by bolting or screwing. In addition, the rotating body 634 is inserted into the lower end of the bearing housing is rotatable and is connected to the blade support tube 612 provided with a plurality of blades 610 is installed to rotate together.
즉 상기 회전축(630)의 하단부에는, 회전축에 끼워져 같이 회전하는 회전체(634)와, 상기 회전체(634)에서 외측으로 연장되는 다수의 브릿지(616), 그리고 다수의 블레이드(610)을 구비하는 블레이드지지관(612)가 설치되어 있고, 이들은 일체로 성형되거나 별도로 성형되어 결합되어 일체화(어셈블리)됨으로써, 같이 회전하도록 구성되고 있음을 알 수 있다. That is, the lower end of the rotating shaft 630 is provided with a rotating body 634, which is fitted to the rotating shaft to rotate together, a plurality of bridges 616 extending outward from the rotating body 634, and a plurality of blades 610 It is understood that the blade support pipe 612 is provided, and these are configured to rotate together by being integrally molded or separately molded and combined to be integrated (assembled).
상기 브릿지(616)의 외측단부에는 워터펌프(600)가 결합된다. 즉 본 발명의 워터펌프(600)는, 메인커버(500)의 중심부분 저면에서 회동 가능하게 지지되는 회전축(630)과 연동하면서 회전 가능하게 지지되고 있음을 알 수 있다. 이와 같이 메인커버(500)의 헤드부(520)의 저면에 회전 가능하게 지지되는 워터펌프(600)는, 원통형상 또는 역원뿔 형상으로 성형될 수 있는데, 도시한 실시예에서는 역원뿔 형상을 가지고 있음을 알 수 있다. The water pump 600 is coupled to the outer end of the bridge 616. That is, it can be seen that the water pump 600 of the present invention is rotatably supported while interlocking with the rotation shaft 630 which is rotatably supported at the bottom of the central part of the main cover 500. As such, the water pump 600 rotatably supported on the bottom surface of the head part 520 of the main cover 500 may be formed in a cylindrical shape or an inverted cone shape. In the illustrated embodiment, the water pump 600 has a inverted cone shape. It can be seen that.
이와 같이 역원뿔 형상으로 성형되는 워터펌프(600)는 회전 시 진동 발생의 최소화할 수 있는 측면에서는 원통형상 보다 유리한 것으로 기대된다. 또한 상기 워터펌프(600)가 역원뿔 형상으로 성형되는 것은, 실질적으로 회전에 기초한 원심력을 이용하여 물이 상부로 보다 원활하게 이동할 수 있는 장점도 기대된다. Thus, the water pump 600 is formed in a reverse cone shape is expected to be more advantageous than the cylindrical shape in terms of minimizing the generation of vibration during rotation. In addition, the water pump 600 is formed in an inverted cone shape, it is also expected that the water can be moved more smoothly to the top by using a centrifugal force based on the rotation substantially.
그리고 상기 워터펌프(600)는, 공기의 통과를 위하여 상단부가 개구되어 있다. 그리고 도시한 실시예에서, 상기 워터펌프(600)는 역원뿔 형상의 측벽부분(602)과, 이러한 측벽 사이에 형성되는 다수의 열린부분(604)을 구비하고 있다. 상기 열린부분(604)은 워터펌프(600)의 전체 높이에 대하여 성형되는 것이 바람직하다. In addition, the water pump 600 has an upper end opening for passage of air. In the illustrated embodiment, the water pump 600 has an inverted sidewall portion 602 and a plurality of open portions 604 formed between the sidewalls. The open portion 604 is preferably molded over the entire height of the water pump 600.
그리고 상기 워터펌프(600)의 측벽부분(602)의 내측에는 다수의 물안내홈(606)이 상하 방향으로 성형되어 있다. 이러한 물안내홈(606)은 실질적으로 회전 시 원심력을 이용하여 싸이클로바디의 저면에 고인 물을 상방으로 펌핑하기 위한 것이다. 그리고 도시한 실시예에서의 물안내홈(606)에 대신하여 상하 방향으로 연장된 일정한 높이를 가지는 벽(또는 리브)으로 대신하는 것도 가능함은 물론이고, 이 때 이러한 벽과 벽 사이의 오목한 부분이 도시한 실시예에서의 물안내홈(606)에 대응하게 될 것이다. In addition, a plurality of water guide grooves 606 are formed in the up and down direction inside the side wall part 602 of the water pump 600. The water guide groove 606 is for pumping the water accumulated in the bottom of the cyclo body upward by using the centrifugal force during the rotation. And it is also possible to replace with a wall (or rib) having a constant height extending in the vertical direction in place of the water guide groove 606 in the illustrated embodiment, wherein the concave portion between the wall and the wall Will correspond to the water guide groove 606 in the illustrated embodiment.
이와 같은 물안내홈(606)은 실질적으로 물이 그 내부를 따라 상방으로 올라갈 수 있는 것이면 어떠한 형상을 가지는 것도 가능하며, 도시한 바와 같이 수직에 가까운 상하 방향의 홈으로 한정될 수 없음은 당연하다. 그리고 상기 측벽부분(602) 사이에 성형되는 열린 부분(604)은 도시한 바와 같이 수직선에 대하여 일정한 경사를 가지도록 성형되어 있다. 따라서 상기 물안내홈(606)의 가장 상단부는 경사진 열린부분(604)을 따라서 열린 상태(개구 상태)가 된다. The water guide groove 606 may have any shape as long as water can substantially rise upward along the inside thereof, and it is natural that the water guide groove 606 may not be limited to a vertical groove close to the vertical as shown. . The open portion 604 formed between the side wall portions 602 is shaped to have a constant inclination with respect to the vertical line as shown. Therefore, the uppermost part of the water guide groove 606 is in an open state (opening state) along the inclined open portion 604.
그리고 상술한 물안내홈(606)은, 일정한 간격을 가지고 상측방향으로 연속적으로 연장되어 있기 때문에 상기 열린부분(604)에는 물안내홈(606)의 출구(608)가 성형된다. 또한 열린부분(604)은 일정한 기울기를 가지는 경사 상태로 성형되기 때문에, 물안내홈(606)의 출구는 싸이클론바디(30) 내부에서 상하에 걸쳐 다수 개 성형된다고 할 수 있다. 상기 물안내홈(606)의 출구(608)는, 상기 열린 부분(604)의 가장 낮은 부분부터 가장 높은 부분에 걸쳐 다수개가 연속적으로 성형되어 있음을 알 수 있다.In addition, since the above-described water guide groove 606 continuously extends upward at regular intervals, an outlet 608 of the water guide groove 606 is formed in the open portion 604. In addition, since the open portion 604 is formed in an inclined state having a constant inclination, it can be said that a plurality of outlets of the water guide grooves 606 are formed up and down inside the cyclone body 30. The outlet 608 of the water guide groove 606, it can be seen that a plurality of continuously formed from the lowest portion to the highest portion of the open portion 604.
그리고 상기 워터펌프(600)의 하단부(620)는 싸이클론바디(310)의 내부에 담겨있는 물에 잠겨 있는 상태이다. 상기 워터펌프(600)의 하단부(620)는, 물이 그 내측으로 들어올 수 있도록 적어도 일부가 개방된 형상을 가지고 있다. 또한 워터펌프(600)의 내측면에 성형되는 물안내홈(606)은, 워터펌프(600)의 하단부까지 연장 성형되어 있다. 따라서 상기 워터펌프(600)가 회전하면, 싸이클론바디(310)의 내부에 있는 물은 회전에 의하여 발생하는 원심력에 의하여 물안내홈(606)을 따라서 상승하게 된다. 그리고 물안내홈(606)을 따라 상승하는 물은 열린부분(604)에 성형되어 있는 그 출구(608)를 통하여 외부로 분사 또는 비산될 것이다. In addition, the lower end 620 of the water pump 600 is in a state of being immersed in water contained in the cyclone body 310. The lower end portion 620 of the water pump 600 has a shape in which at least a part of the water pump 600 is open so that water can enter the inside thereof. In addition, 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. Therefore, when the water pump 600 rotates, the water inside the cyclone body 310 is raised 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 sprayed or scattered out through the outlet 608 formed in the open portion 604.
이때 상기 열린부분(604)은 전체 높이에 대하여 또는 상하 방향에 대하여 일정한 경사를 가지고 성형되어 있음과 동시에 상기 물안내홈(606)은 일정한 간격으로 다수개 성형되어 있기 때문에, 일정한 높이 이상에서 부터 워터펌프(600)의 전체 높이에 걸쳐서, 물은 열린부분(604)을 통하여 외부로 비산될 것이다. 이러한 물의 비산은, 실질적으로 싸이클론바디(310)의 내부에서 물은 전체 높이에 대하여 균일하게 비산된다는 것을 의미한다고 할 수 있다. At this time, since the open portion 604 is formed with a predetermined inclination with respect to the overall height or up and down direction and at the same time a plurality of the water guide grooves 606 are formed at regular intervals, water from a certain height or more Over the entire height of the pump 600, water will splash out through the open portion 604. Such water scattering may substantially mean that the water is uniformly scattered with respect to the entire height inside the cyclone body 310.
예를 들면 상기 워터펌프(600)를 상부와 하부의 지름이 동일하거나 유사한 원통형상을 성형하게 되면, 특히 하단부에서 회전에 의하여 진동이 더욱 발생할 우려가 더욱 높아진다. 본 실시예에서는, 상기 워터펌프(600)를 역원뿔 형상으로 하거나, 적어도 부분적인 역원뿔 형상으로 함으로써, 하단부에서의 무게의 편심을 최대한 억제하고 이로 인한 회전 시의 진동을 억제할 수 있도록 구성하는 것이다. For example, when the water pump 600 is formed in a cylindrical shape having the same diameter or the same diameter as that of the upper and lower portions, in particular, there is a high possibility that the vibration is further generated by the rotation at the lower portion. In this embodiment, by forming the water pump 600 in the reverse cone shape or at least a partial inverted cone shape, it is configured to suppress the eccentricity of the weight at the lower end as possible and thereby suppress the vibration during rotation will be.
그리고 다음에는 이와 같은 워터펌프(600)를 메인커버(500)의 저면에 회전 가능하게 지지하는 다른 실시예에 대하여 살펴보기로 한다. 본 실시예는 워터펌프(600)가 자석에서 발생하는 자력에 의하여, 메인커버(500)에 착탈 가능하게 구성되는 실시예이다. 이하 본 실시예의 설명에 있어서, 실질적으로 위에서 설명한 것과 동등한 구성요소는 동일한 도면부호를 부여하면서 설명한다.Next, another embodiment of supporting the water pump 600 rotatably on the bottom of the main cover 500 will be described. This embodiment is an embodiment in which the water pump 600 is detachably attached to the main cover 500 by the magnetic force generated from the magnet. In the following description of the present embodiment, components substantially equivalent to those described above will be described with the same reference numerals.
도 7에 도시한 바와 같이, 상기 메인커버(500)의 중앙에 있는 헤드부(520)의 저면에는, 상하에서 일정한 간격을 가지고 있는 한 쌍의 베어링(622,624)에 의하여 수직으로 배치되는 회전축(630)이 회전 가능하게 지지되고 있다. 상기 회전축(630)은 임의로 하방으로 빠지지 않는 구조를 가지고 있음은 당연하고, 예를 들면 최상단부에 베어링(622)에 지지되는 헤드(634)가 성형되어 있다. As shown in FIG. 7, a rotation shaft 630 vertically disposed on a bottom surface of the head part 520 in the center of the main cover 500 by a pair of bearings 622 and 624 having a predetermined distance from the top and the bottom. ) Is rotatably supported. Naturally, the rotating shaft 630 has a structure that does not fall downward arbitrarily, for example, a head 634 supported by the bearing 622 is formed at the uppermost end thereof.
그리고 상기 베어링(622,624) 및 베어링(622,624)을 지지하는 베어링지지블럭(626)은 금속재 등으로 성형되는 것이 충분한 지지강도를 제공하기 위하여 바람직하다고 할 수 있다. 그리고 상기 베어링지지블럭(626)은, 헤드부(520)의 저면에 서 이탈하지 않도록 지지되는데, 예를 들면 베어링하우징(628)에 의하여 헤드부(520)의 저부에 지지되고 있음을 알 수 있다. 베어링지지블럭(626)은 다른 체결요소 등을 이용하여 헤드부(520)의 저면에 고정되는 것도 가능함은 물론이다. In addition, the bearings 622 and 624 and the bearing support blocks 626 supporting the bearings 622 and 624 may be preferable in order to provide sufficient support strength to be formed of a metal material or the like. In addition, the bearing support block 626 is supported so as not to be detached from the bottom of the head 520, for example, the bearing housing 628 is supported by the bottom of the head 520. . The bearing support block 626 may also be fixed to the bottom of the head portion 520 using other fastening elements.
상기 회전축(630)은 하방으로 연장된 후, 너트(632)가 단부에 채결되어 일정한 면적을 가지도록 하고 있다. 그리고 상기 너트(632)의 하측에는 마그네트(640)가 내장되어 있는 마그네트하우징(642)이 자력에 의하여 착탈 가능하게 고정된다. 상기 마그네트하우징(642)은 하방으로 연장된 다수(예를 들면 3개)의 체결후크(644)가 워터펌프(600)에 후킹되어 있다. After the rotation shaft 630 extends downward, the nut 632 is formed at the end to have a constant area. And the lower side of the nut 632, the magnet housing 642, in which the magnet 640 is built, is detachably fixed by magnetic force. In the magnet housing 642, a plurality of fastening hooks 644 extending downward are hooked to the water pump 600.
따라서 본 실시예에서의, 워터펌프(600)를 메인커버(500)의 중앙 저부에 조립하기 위한 구조를 정리하면, 한 쌍의 베어링(622,624)을 통하여 회전축(630)이 헤드부분(520)의 저면에 회전 가능하게 지지되고 있다. 그리고 상기 회전축(630)의 저면에는 마그네트(640)를 내장하고 있는 마그네트하우징(642)이 자력으로 착탈되며, 마그네트하우징(642)은 워터펌프(600)과 탈착 가능하게 연결되고 있다. Therefore, in this embodiment, if the structure for assembling the water pump 600 in the central bottom of the main cover 500, the rotation shaft 630 through the pair of bearings (622, 624) of the head portion 520 It is rotatably supported by the bottom. In addition, the magnet housing 642 having the magnet 640 embedded therein is detachably attached to the bottom of the rotation shaft 630, and the magnet housing 642 is detachably connected to the water pump 600.
여기서 자성체인 회전축(630)의 하단부는 너트(632)를 통하여 자력에 반응하는 면적을 충분히 확보하고 있다. 여기서 상기 너트(632)의 저면 전체를 커버할 수 있는 평판의 금속재를 더 개재하는 것도 가능할 것임은 당연하다. 그리고 상기 마그네트하우징(642)과 워터펌프(600)를 서로 분해 및 조립이 가능하도록 서로 연결하는 구조에 있어서는 많은 다른 변형이 가능할 것임은 당연하다. Here, the lower end of the rotating shaft 630, which is a magnetic body, sufficiently secures an area reacting to the magnetic force through the nut 632. Of course, it will be possible to further interpose a metal material of the plate that can cover the entire bottom of the nut 632. In addition, in the structure in which the magnet housing 642 and the water pump 600 are connected to each other to be disassembled and assembled, it is obvious that many other modifications are possible.
그리고 본 발명에 의하면, 상기 싸이클론바디(310)는 투시 가능한 합성수지재로 성형되고, 상기 싸이클론바디(310)이 위치하는 부분의 케이싱(10) 상부로 투시 가능한 합성수지재로 성형된다. 따라서 상기 워터펌프(600)의 회전에 의하여 싸이크론바디(310) 내부에서 비산되는 물은, 외부에서 시각으로 인식할 수 있게 될 것이다. 즉, 본 발명에 의한 공기청정기는, 상술한 싸이클론바디(310)의 내부에서 물이 비산되고, 이와 동시에 선회류가 형성되는 것을 외부에서 보는 사람에게 노출시키고 있음을 알 수 있다. 이러한 점은 시각적으로, 공기 정화 및 가습에 대한 효과를 사용자에게 인식시킬 수 있는 장점을 기대할 수 있을 것이다. In addition, according to the present invention, the cyclone body 310 is formed of a transparent synthetic resin material, and the cyclone body 310 is formed of a transparent resin material visible to the upper casing 10 of the portion where the cyclone body 310 is located. Therefore, water scattered inside the cyclone body 310 by the rotation of the water pump 600 will be able to recognize visually from the outside. That is, it can be seen that the air cleaner according to the present invention exposes to the outside viewer that water is scattered inside the cyclone body 310 and the swirl flow is formed at the same time. This can be expected to visually benefit the user to recognize the effect on air purification and humidification.
그리고 본 발명에 의하면, 싸이클론바디(310)의 내부로 들어오는 에어플로는, 상술한 연결통로(R)를 통하여 유입되는 선회류임은 상술한 바와 같다. 그리고 이러한 선회류에 기초하여, 워터펌프가 회전하게 되도록 구성되고 있으며, 워터펌프(600)는 회전해야, 내부의 물을 싸이클론 바디의 내부에서 비산시킴으로써, 본 발명의 공기청정기가 동작할 수 있을 것임을 알 수 있다. In addition, according to the present invention, the airflow coming into the cyclone body 310 is the swirl flow flowing in through the connection passage R described above. And based on this swirling flow, the water pump is configured to rotate, the water pump 600 must rotate, the air purifier of the present invention can operate by scattering the water in the interior of the cyclone body It can be seen that.
여기서 상기 워터펌프(600)를 회전시키기 위한 구성에서는 다양한 변형이 가능함은 물론이다. 예를 들면 상기 메인커버(500)의 헤드부(520)에 장착되는 소형의 모터를 이용하여 상기 워터펌프(600)를 회전시키도록 하는 것도 가능하다. 그리고 도시한 실시예에서와 같이, 상기 연결통로(R)를 통하여 싸이클론용기(310)의 내부로 유입되고, 싸이클론용기(310) 내부에서 배출공(510)을 통하여 배출되는 공기의 흐름을 이용하여 상기 워터펌프(600)를 회전시키도록 구성하는 것도 가능하다. Here, in the configuration for rotating the water pump 600, various modifications are possible, of course. For example, it is also possible to rotate the water pump 600 by using a small motor mounted to the head part 520 of the main cover 500. As shown in the illustrated embodiment, the flow of air introduced into the cyclone container 310 through the connection passage R and discharged through the discharge hole 510 inside the cyclone container 310 is obtained. It is also possible to configure to rotate the water pump 600 by using.
이와 같이 에어플로를 이용하여 상기 워터펌프(600)를 회전시키는 구성을 가지는 실시예에 대하여 자세하게 살펴보기로 한다. 싸이클론바디(310)의 내부로 안내되는 에어플로는 선회류를 형성하는 상태로 유입되는데, 이러한 선회류는 실질적으로 싸이클론바디(310)의 내측면에 근접한 부분을 따라 형성되고 있다. 그리고 상기 메인커버(500)의 중심부분에는 원형을 이루도록 배열된 배출공(510)이 있기 때문에, 싸이클론 원리에 의하여 선회하는 공기를 상기 배출공(510)을 통하여 외부로 배출된다. As described above, an embodiment having a configuration of rotating the water pump 600 using airflow will be described in detail. The airflow guided into the cyclone body 310 is introduced into a state of forming a swirl flow, and the swirl flow is formed along a portion substantially adjacent to the inner surface of the cyclone body 310. And since the discharge hole 510 is arranged in a central portion of the main cover 500 to form a circle, the air turning by the cyclone principle is discharged to the outside through the discharge hole 510.
여기서 상기 배출공(510)은 싸이클론바디(310)의 중심부분에 형성되어 있기 때문에, 싸이클론바디(310)의 내부 중심부분에서는 상승하는 기류가 형성된다. 즉, 싸이클론바디(310)의 내부에서의 공기의 흐름을 살펴보면, 싸이클론바디(310)의 내면에 근접한 외측 부분에서는 선회류가 성형되고 있으며, 싸이클론바디(310)의 중심부분에서는 상기 배출공(510)을 통하여 외부로 배출되는 공기가 상승하는 기류를 형성하고 있는 것이다. Here, since the discharge hole 510 is formed in the central portion of the cyclone body 310, the rising air flow is formed in the inner central portion of the cyclone body 310. That is, when looking at the flow of air in the cyclone body 310, the swirl flow is formed in the outer portion close to the inner surface of the cyclone body 310, the discharge portion in the central portion of the cyclone body 310 The air discharged to the outside through the ball 510 is to form an air stream rising.
그리고 상기 회전축(630)의 외측면에 형성되어 있는 다수 개의 블레이드(610)는. 상승기류에 접촉하여 싸이클론바디(310) 내부에서 형성되는 선회류와 동일한 방향으로 블레이드지지관(612)를 회전시키는 방향으로 성형되어 있다. 따라서 싸이클론바디(310)의 내부 중앙에서 상승하는 기류가 상기 블레이드(612)에 부딪히게 되면, 상기 블레이드지지관(612)을 반시계 방향(평면도 상에서 볼 때)으로 회전시키게 된다. 그리고 이러한 블레이드 및 블레이드지지관(612)의 회전은, 실질적으로는 브릿지(616)를 통하여 워터펌프(600)를 위와 같은 방향으로 회전시키게 되는 것이다. And a plurality of blades (610) formed on the outer surface of the rotating shaft (630). The blade support tube 612 is rotated in the same direction as the swirl flow formed in the cyclone body 310 in contact with the upward airflow. Therefore, when the air flow rising from the inner center of the cyclone body 310 hits the blade 612, the blade support tube 612 is rotated in a counterclockwise direction (as viewed in plan view). The rotation of the blade and the blade support tube 612 substantially rotates the water pump 600 through the bridge 616 in the same direction as above.
도시한 실시예에서, 싸이클론바디(310)로 유입되는 선회류는, 싸이클론바디(310)의 중앙부분에서 상승기류를 형성하게 되고 이러한 상승기류는 배출공(510)을 통하여 배출되고 있다. 여기서 상기 배출공(510)을 통하여 배출되기 직전에 상승기류는 상술한 블레이드(610)에 접촉하여 블레이드지지관(612)을 회전시키도록 구성되고 있음을 알 수 있다. 그리고 블레이드(610)의 회전은 브릿지(616)를 통하여 워터펌프(600)를 원하는 방향으로 회전시키고 있다. In the illustrated embodiment, the swirl flow flowing into the cyclone body 310 forms an upward airflow at the central portion of the cyclone body 310, and the upward airflow is discharged through the discharge hole 510. Here, it can be seen that the air flow immediately before being discharged through the discharge hole 510 is configured to rotate the blade support pipe 612 in contact with the blade 610 described above. The blade 610 rotates the water pump 600 in the desired direction through the bridge 616.
이와 같은 구성을 가지는 실시예에서, 상기 워터펌프(600)의 회전은, 팬모터어셈블리(400)에 의하여 출구(12)를 통하여 들어오는 공기의 흐름에 의한 것임을 알 수 있다. 이와 같이 상기 팬모터어셈블리(400)에 의하여 만들어지는 에어플로에 의하여, 상기 워터펌프(400)가 회전하게 된다는 것은 워터펌프를 회전시키기 위한 별도의 모터를 필요로 하지 않는 여러 가지 장점을 가질 수 있음을 알 수 있다. 그리고 워터펌프(400)의 회전은 상술한 바와 같이, 싸이클론바디(310) 내부에 고여 있는 물에 외력을 가하여 물 입자를 비산시킴은 상술한 바와 같다. In the embodiment having such a configuration, it can be seen that the rotation of the water pump 600 is due to the flow of air entering through the outlet 12 by the fan motor assembly 400. As such, the water pump 400 being rotated by the air flow formed by the fan motor assembly 400 may have various advantages of not requiring a separate motor for rotating the water pump. It can be seen. As described above, the rotation of the water pump 400 scatters water particles by applying an external force to the water accumulated in the cyclone body 310.
다음에는 이상과 같은 구성을 가지는 본 발명의 공기청정기의 전체적인 동작에 대하여 살펴보기로 한다. 여기서 본 발명의 공기청정기의 동작 설명은, 상기 팬(420)에 의하여 성형되는 전체적인 공기의 흐름을 따라 설명하고자 한다. 먼저 본 발명의 공기청정기가 동작하게 되면, 팬모터어셈블리(400)가 구동되면서, 케이싱(10) 외부의 공기가 입구(12)를 통하여 내부로 유입된다. Next will be described the overall operation of the air cleaner of the present invention having the configuration as described above. Here, the description of the operation of the air cleaner of the present invention will be described according to the overall air flow formed by the fan 420. First, when the air cleaner of the present invention operates, while the fan motor assembly 400 is driven, air outside the casing 10 is introduced into the inside through the inlet 12.
이렇게 외부(실내)에서 케이싱(10) 내부로 유입되는 공기는, 상기 필터(210)를 통과하게 되는데, 이러한 과정에서 1차적으로 불순물이 여과된다. 즉, 제1필터링부(200)를 구성하고 있는 헤파 필터(210)에 의하여 1차적으로 불순물이 제거되는데, 여기서 상기 필터(210)는 원하는 사양 및 기능을 가지는 것으로 선택할 수 있을 것임은 상술한 바와 같다. 예를 들면 미세 먼지와 같은 이물질은 물론이고, 악취 제거가 가능한 필터를 일부 포함시킬 수도 있어서, 필터(210)에 의하여 악취제거의 효과도 기대할 수 있다. In this way, the air flowing into the casing 10 from the outside (indoor) passes through the filter 210, and in this process, impurities are primarily filtered. That is, impurities are firstly removed by the HEPA filter 210 constituting the first filtering unit 200, wherein the filter 210 may be selected to have a desired specification and function. same. For example, as well as foreign matters such as fine dust, and may include a filter capable of removing the odor, the filter 210 can also be expected to the effect of removing the odor.
도 1에 도시한 실시예에서, 상기 필터(210)는 원통 형상의 필터로 구성되고 있으며, 상기 팬(420)은 원심팬으로 구성되고 있으나, 본 발명은 이러한 구성에 의하여 한정될 수 없음은 자명하다. 상기 팬(420)은 입구(12)를 통하여 외기를 유입시키면서 이러한 외기가 필터(210)을 통과할 수 있도록 에어플로를 형성하는 것이면 충분하다. In the embodiment shown in Figure 1, the filter 210 is composed of a cylindrical filter, the fan 420 is composed of a centrifugal fan, the present invention is not limited by this configuration is obvious Do. It is sufficient that the fan 420 forms an airflow such that the outside air can pass through the filter 210 while introducing the outside air through the inlet 12.
본 발명에서 팬(420)을 회전시키는 회전축(412)은, 모터부(410)와 댐퍼(DR)를 통하여 연결되어 있음은 상술한 바와 같다. 따라서 상대적으로 큰 크기의 팬(420)의 회전 시 발생할 수 있는 진동은 상기 댐퍼(DR)에 의하여 흡수될 수 있을 것임은 상술한 바와 같다. 여기서 상기 댐퍼(DR)에 의하여 회전체인 팬(420)의 진동이 흡수된다는 것은 실질적으로 팬(420)이 보다 원활하게 회전할 수 있어서 에어플로의 발생에 유리함은 물론이고, 진동 및 소음 저감에도 충분한 기능을 가지는 것은 당연하다고 할 수 있다. In the present invention, the rotating shaft 412 for rotating the fan 420 is connected to the motor unit 410 through the damper DR as described above. Therefore, as described above, the vibration that may occur when the relatively large size of the fan 420 rotates may be absorbed by the damper DR. In this case, the vibration of the fan 420 which is the rotating body is absorbed by the damper DR may substantially allow the fan 420 to rotate more smoothly. It is natural to have enough functions.
그리고 상기 필터(210)를 통과한 공기는, 상방으로 이동하면서 팬(420)에 의하여 레디얼 방향으로 이동하게 되는데, 이는 에어플로가 케이싱(10)의 내측부분을 향하여 방사상으로 흐르는 것을 의미한다. 상기 팬(420)의 회전에 의하여 방사상 외측으로 나가는 공기는 연결통로(R)의 외측벽, 즉 외부관(444)의 내측에 접촉하게 된다. 그러나 외부관(444)은 케이싱(10)와는 별도로 그 내측에 성형된 부분이고, 더욱이 케이싱(10)과 외부관(444) 사이에는 진동흡수부재(DR)가 개재되어 있기 때문에, 발생한 에어플로에 기초하여 케이싱(10) 내부에서 발생하는 진동 및 소음은 대부분 흡수될 수 있게 될 것이다. The air passing through the filter 210 is moved upward in the radial direction by the fan 420 while moving upward, which means that the airflow flows radially toward the inner portion of the casing 10. The air exiting radially outward by the rotation of the fan 420 comes into contact with the outer wall of the connection passage R, that is, the inner side of the outer tube 444. However, the outer tube 444 is a portion formed inside thereof separately from the casing 10, and furthermore, since the vibration absorbing member DR is interposed between the casing 10 and the outer tube 444, the generated air flows. On the basis, most of the vibration and noise generated inside the casing 10 will be able to be absorbed.
여기서 상기 팬(420)에 의하여 생성되는 공기의 흐름은 상술한 연결통로(R)로 흐르게 되는데, 이때 회전하는 팬(420)에 의하여 상기 연결통로(R)로 흐르는 공기의 흐름은 선회류를 형성하게 되고, 이러한 공기의 흐름 방향이 도 6에 상세하게 도시되어 있다. 이하 본 발명의 공기청정기의 동작 설명에서는 도 6을 같이 참고하면 이해가 더욱 쉬울 것이다.Here, the flow of air generated by the fan 420 flows into the above-described connection passage (R), wherein the flow of air flowing into the connection passage (R) by the rotating fan 420 forms a swirl flow. This air flow direction is shown in detail in FIG. 6. In the following description of the operation of the air purifier of the present invention will be easier to understand with reference to FIG.
상기 연결통로(R)의 상단부에 이른 에어플로는 메인커버(500)에 의하여 상면이 막혀 있기 때문에, 상부가 열린 싸이클론바디(310)의 내부로 유입된다. 이렇게 싸이클론바디(310)의 내부로 유입되는 공기도 선회류를 유지하게 될 것이고, 그 과정에서 메인커버(500)에 성형된 나팔관 형상의 에어가이드부(530) 및 안내리브(534)의 도움을 받을 것임은 당연하다. Since the upper surface of the air flow that reaches the upper end of the connection passage (R) is blocked by the main cover 500, the upper flows into the open cyclone body 310. Thus, the air flowing into the cyclone body 310 will also maintain the swirl flow, in the process the help of the fallopian tube-shaped air guide portion 530 and the guide ribs 534 formed in the main cover 500 It is natural to receive.
그리고 싸이클론바디(310)의 내부에서는, 가장자리 부분에서는 선회류가 성형되고, 배출공(510)이 위치하는 중앙부분에서는 상승기류가 형성되는 것은 당연하다. 또한 이렇게 싸이클론바디(310)의 중앙에서 상승하는 공기는 블레이드(610)에 풍압을 가하여, 실질적으로는 워터펌프(600)를 회전시키게 되는 것도 상술한 바와 같다. And inside the cyclone body 310, it is natural that the swirl flow is formed at the edge portion, and the rising air flow is formed at the center portion where the discharge hole 510 is located. In addition, as described above, the air rising in the center of the cyclone body 310 applies the wind pressure to the blade 610 to substantially rotate the water pump 600.
그리고 싸이클론바디(310)의 내부에는 물이 고여 있고, 이러한 물은 워터펌프(600)의 하단부(620) 내부까지 들어와 있을 것이다. 상술한 바와 같이, 상기 워터펌프(600)가 회전하게 되면, 싸이클론바디(310) 내부에서, 워터펌프(600)의 하단부(620) 내측에 들어 있는 물은, 원심력에 의하여 워터펌프(600) 하단부(620)의 측벽부분(602) 내부에 형성된 물안내홈(606)을 따라서 상방으로 이동하게 된다. Water is accumulated in the cyclone body 310, and the water may enter the inside of the lower end 620 of the water pump 600. As described above, when the water pump 600 is rotated, the water contained in the lower end portion 620 of the water pump 600 in the cyclone body 310, the water pump 600 by the centrifugal force It moves upward along the water guide groove 606 formed in the side wall portion 602 of the lower end 620.
이렇게 물안내홈(606)을 따라서 이동하는 물은, 열린부분(604)에 성형된 물안내홈(606)의 다수의 출구(608)를 통하여 외부로 비산된다. 이러한 물안내홈(606)의 출구는 하단부에서 상단부에 걸쳐 일정한 간격으로 성형되어 있고, 열린부분(604)은 경사를 가지고 성형되어 있기 때문에, 전체적으로 물이 균일하게 외측으로 비산될 수 있게 된다. The water moving along the water guide groove 606 is scattered to the outside through a 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 to the upper end, and since the open portion 604 is formed with an inclination, the water can be uniformly scattered outward as a whole.
여기서 상기 싸이클론바디(310) 및 그에 대응하는 케이싱(10)은 내부를 투시할 수 있는 재질로 성형되기 때문에, 싸이클론바디(310) 내부에서 비산되는 물은 사용자가 직접 시각으로 인식할 수 있게 될 것이다. 이와 같이 물이 비산되는 상태를 시각으로 확인할 수 있다는 것은, 본 발명의 공기청정기가 실질적으로 작동하고 있음과 동시에, 충분한 가습효과를 사용자에게 인식시킬 수 있다는 것을 의미하는 것이라고도 할 수 있다. Here, since the cyclone body 310 and the corresponding casing 10 are formed of a material that can see through the inside, water scattered inside the cyclone body 310 can be directly recognized by the user. Will be. In this way, the state in which water is scattered can be confirmed visually, which means that the air purifier of the present invention is substantially operated and a sufficient humidification effect can be recognized by the user.
그리고 이와 같은 현재의 상태는, 상기 워터펌프(600)가 회전하면서 싸이클론바디(310) 내부에서 물이 비산되고 있음과 동시에, 싸이클론바디(310) 내부에서는 선회류가 형성되고 있는 중이라고 할 수 있다. 상기 싸이클론바디(310) 내부에서 선회류가 성형된 상태에서 물이 이러한 선회류를 향하여 비산되면, 비산되는 물 입자는 실질적으로 반복하여 회전하는 공기에 노출된다. 또한 싸이클론바디(310)의 내부에서 공기는 다수 회 반복하여 선회한 후, 중심부분에서 상승하게 되는데, 실질적으로 워터펌프(600)에 의하여 비산되는 물 입자는 수회 반복하여 선회하는 물과 충분한 시간 동안 접촉하게 된다. In this current state, as the water pump 600 rotates, water is being scattered in the cyclone body 310, and whirlpool flow is being formed in the cyclone body 310. have. When water is scattered toward the swirl in a state in which the swirl flow is formed in the cyclone body 310, the scattered water particles are exposed to the air which rotates substantially repeatedly. In addition, the air inside the cyclone body 310 is repeatedly rotated a plurality of times, and then rises at the center portion. Substantially, water particles scattered by the water pump 600 are repeatedly rotated several times and sufficient time. While contacting.
이와 같이 비산되는 물방울이 적어도 다수회 반복하는 선회류에 노출된다는 것은 실질적으로, 입구(35)를 통하여 유입되는 공기와 워터펌프(600)를 통하여 비산되는 물방울과의 접촉 표면적이 충분히 확보된다는 것을 의미한다. 그리고 비산되는 물방울과 공기와의 접촉 표면적이 넓다는 것은, 실질적으로 공기 중에 포함된 이물질이 표면장력 및 흡착력 등에 의하여 물에 포획된다는 것과 동일한 의미를 가진다고 할 수 있다. The exposure of the droplets scattered in this manner to at least a plurality of repeated swirl flows substantially means that the contact surface area between the air flowing through the inlet 35 and the droplets scattered through the water pump 600 is sufficiently secured. do. In addition, having a large contact surface area between water droplets and air scattered may have the same meaning as that the foreign matter contained in the air is captured in water by surface tension and adsorption force.
또한 비산되는 물방울과 공기와의 접촉 표면적이 넓다는 것은 실질적으로 공기와의 접촉에 의하여 증기화되는 물의 양도 많아진다는 것을 의미한다. 더욱이 공기가 미세한 물입자와 충분한 시간 동안 접촉한다는 것은, 공기 중에 포함되어 있는 냄새 입자를 포집하여, 공기를 충분히 탈취시킬 수 있다는 것을 의미하는 것이기도 하다. In addition, the large contact surface area of the water droplets and air that are scattered means that the amount of water vaporized by the contact with the air is also increased. Furthermore, contact of the air with the fine water particles for a sufficient time also means that the odor particles contained in the air can be captured to sufficiently deodorize the air.
이와 같이 본 발명에서는, 싸이클론 바디의 내부에서 선회류를 형성하고, 이러한 선회류에 물방울을 비산시킴으로써 물에 포함된 이물질(악취 입자 포함)의 포집 능력이 우수함과 동시에 가습 성능 또한 높은 상태를 확보할 수 있도록 구성하고 있음을 알 수 있다. 즉, 제2필터링부(300)를 구성하고 있는 싸이클론바디(310)는, 물 입자가 선회류와의 충분한 접촉에 의하여, 공기 중의 이물질을 포집하는 것과 동시에 배출공(510)으로 배출되는 공기를 충분히 가습하고 있음을 알 수 있을 것이다. As described above, in the present invention, the swirl flow is formed inside the cyclone body, and the water droplets are scattered on the swirl flow, so that the foreign substances (including odor particles) contained in the water are excellent and the humidification performance is also high. You can see that it is configured to do so. That is, the cyclone body 310 constituting the second filtering part 300 collects foreign substances in the air by sufficient contact with the swirl flow, and simultaneously discharges the air to the discharge hole 510. You can see that it is sufficiently humidified.
이와 같은 물방울의 비산 및 선회류의 선회과정이 지속적으로 반복되면, 싸이클론바디(310) 내부에서 상대적으로 무거운 물 입자는 이물질 등과 같이 하방으로 가라앉게 되고, 상대적으로 가벼운 물 입자는 싸이클론바디(310) 상부의 개구된 중앙부분 출구(38)을 통하여 실내(외부)로 배출될 것이다. 그리고 이렇게 배출되는 공기는 실질적으로 충분하 가습량을 제공할 수 있음은 물론이고, 이물질이 충분히 필터링된 정화된 공기임은 당연하다고 할 수 있다. When the water droplets splash and the swirl flow of the swirl flow is continuously repeated, the relatively heavy water particles in the cyclone body 310 sinks downward, such as foreign matter, and the relatively light water particles are cyclone bodies ( 310 it will be discharged into the interior (outside) through an open central portion outlet 38. In addition, the discharged air is substantially sufficient to provide a humidification amount, and it is a matter of course that the foreign matter is purified air that is sufficiently filtered.
상기 싸이클론바디(310)의 내부에서 선회하는 물 입자에 포집된 이물질은 다시 싸이클론바디(310)의 밑부분으로 떨어짐은 상술한 바와 같다. 이러한 이물질에 대한 살균 등을 수행하기 위하여, 상기 싸이클론바디(310)의 내부, 더욱 바람직하게는 싸이클론바디(310)의 하단부에 살균 기능이 있는 램프(예를 들면 UV램프)를 설치하는 것도 가능할 것이다. As described above, the foreign matter collected by the water particles turning inside the cyclone body 310 falls back to the bottom of the cyclone body 310. In order to perform such sterilization on the foreign matter, it is also possible to install a lamp having a sterilizing function (for example, UV lamp) inside the cyclone body 310, more preferably at the lower end of the cyclone body 310. It will be possible.
이상과 같은 구성에 있어서, 상기 메인커버(500)는 케이싱(10)에서 당연히 분리 가능하고, 싸이클론바디(310)도 케이싱(10)에서 분리 가능하게 구성되고 있다. 따라서 실질적으로 물을 담아야 하는 싸이클론바디(310)를 아주 손쉽게 청소하는 것이 가능 하게 되기 때문에, 가습되는 공기가 싸이클론바디의 오염에 의한 어떠한 문제도 발생할 수 없게 된다. In the above configuration, the main cover 500 is naturally detachable from the casing 10, and the cyclone body 310 is also configured to be detachable from the casing 10. Therefore, since it becomes possible to clean the cyclone body 310 which should substantially contain water very easily, the air to be humidified cannot cause any problems due to the contamination of the cyclone body.
그리고 싸이클론바디(310)의 내부 중심의 공기는 위로 상승하는 흐름을 따르게 되어, 메인커버(500)의 배출공(510)을 통하여 외부로 배출된다. 이렇게 배출되기 위하여 상승하는 공기는, 상기 블레이드(610)와 접촉하여 워터펌프(600)를 회전시키는 원동력으로 작용함은 상술한 바와 같고, 이러한 동작의 반복에 의하여 싸이클론바디(310) 내부에서는 공기 중에 포함된 이물질의 제거 및 공기에 대한 충분한 가습이 진행될 수 있을 것이다. In addition, the air in the inner center of the cyclone body 310 follows a flow rising upward, and is discharged to the outside through the discharge hole 510 of the main cover 500. The air rising to be discharged as described above acts as a driving force for rotating the water pump 600 in contact with the blade 610, and the air inside the cyclone body 310 by the repetition of this operation. Removal of foreign matter contained in the air and sufficient humidification to the air may proceed.
