본 발명은 진공청소기에 관한 것으로서, 특히 청소기 몸체 내부로 흡입(suction)된 공기가 정화되어 대기중으로 배기되도록 전동기를 통과한 흡입공기에 실린 먼지를 걸르는 진공청소기용 배기필터의 고정장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to an apparatus for fixing an exhaust filter for a vacuum cleaner that filters dust contained in suction air passing through an electric motor so that the air sucked into the cleaner body is purified and exhausted into the atmosphere. .
일반적으로 진공청소기는 몸체 내부의 구동실 후면에 배기필터를 장착하여 집진실, 집진필터, 구동실의 전동기를 순차통과한 공기의 미세먼지가 배기필터에 걸러져 정화된 상태로 대기에 배기 되도록 구성한다. 따라서 배기필터는 고유 목적인 먼지의 걸름기능을 수행하기 위하여 누진된 먼지를 수시 세척해야 한다. 이에 배기필터의 착탈이 용이하도록 그 고정구조를 구성함은 진공청소기에서 중요한 관건이다.In general, the vacuum cleaner is equipped with an exhaust filter on the back of the driving chamber inside the body so that the fine dust of the air passing through the dust collection chamber, the dust collecting filter, and the driving chamber in the sequential order is exhausted to the atmosphere in a filtered state. . Therefore, the exhaust filter has to clean the accumulated dust from time to time to perform the dust filtering function for its own purpose. Therefore, it is important to configure the fixing structure to easily attach and detach the exhaust filter.
아울러 몸체를 흡배기되는 공기의 유속음을 저하시켜 저소음을 실현함은 진공청소기의 신뢰감을 형성하는 중요한 관건이다.In addition, the low noise by lowering the flow rate of the air intake and exhaust of the body is an important key to build a confidence of the vacuum cleaner.
제1도는 종래 기술에 의한 진공청소기의 내부 구성을 나타낸 단면도이다.1 is a cross-sectional view showing the internal configuration of a vacuum cleaner according to the prior art.
제1도에서 진고청소기는 몸체(10)내부를 전면에 유로수단(미도시)이 끼워지는 흡입공(12)을 형성하고 집진봉지(40)를 장착하며 집진덮개(25)를 갖는 집진실(20)과, 후면에 복수개의 배기공(14)을 형성하고 전동기(50)를 내장하며 구동덮개(35)를 갖는 구동실(30)로 대별한다.In Figure 1, the vacuum cleaner forms a suction hole (12) fitted with a flow path means (not shown) in the front of the body 10, the dust collecting chamber 40 is equipped with a dust collecting chamber having a dust collecting cover 25 ( 20) and a plurality of exhaust holes 14 are formed on the rear surface, and the motor chamber 50 is built-in, and the driving chamber 30 having the driving cover 35 is roughly divided.
상기 집진실(20)와 구동실(30)은 통공(62)을 형성한 칸막이(60)로 연통되도록 구획하고, 칸막이(60)의 통공(62)을 차단하는 집진필터(70)를 장착하며, 구동실(30)후면에는 배기필터(80)를 장착하여 배기공(14)을 차단한다.The dust collecting chamber 20 and the driving chamber 30 are partitioned so as to communicate with the partition 60 formed with the through hole 62, and is equipped with a dust collecting filter 70 for blocking the through hole 62 of the partition 60. In addition, an exhaust filter 80 is mounted on the rear surface of the driving chamber 30 to block the exhaust hole 14.
상기 구성에 의한 종래의 진공청소기는 전류를 인가하여 전동기(50)를 구동하면, 즉 선단에 임펠러를 장착한 회전축이 회전하면 임펠러의 회전에 의해 몸체(10)내부의 공기는 배기공(14)을 통해 몸체(10) 밖으로 배기되어 몸체(10) 내부의 기압이 대기압보다 낮아져 몸체(10)내에 흡입력이 발생한다.The conventional vacuum cleaner according to the above configuration applies an electric current to drive the electric motor 50, that is, when the rotating shaft with the impeller mounted at the front end rotates, the air inside the body 10 is exhausted by the rotation of the impeller 14. Exhausted through the body 10 through the air pressure inside the body 10 is lower than the atmospheric pressure to generate a suction force in the body (10).
따라서 청소대상면 주변의 공기는 이물질과 함께 유로수단으로 유도되어 몸체(10)전면의 흡입공(12)을 통해 집진실(20)로 빨려들어가 이물질은 집진봉지(40)에 모아진다. 집진봉지(40)를 통과한 공기는 전동기(50)등을 보호하기 위하여 집진필터(70)에 먼지가 1차 걸러진 상태로 칸막이(60)의 통공(62)을 통해 전동기(50)로 흡배기된다. 배기된 공기는 배기필터(80)에 미세먼지가 2차 걸러진 상태로 정화되어 배기공(14)을 통해 몸체(10) 외부로 배기된다.Therefore, the air around the object to be cleaned is guided to the flow path means together with the foreign matter is sucked into the dust collecting chamber 20 through the suction hole 12 on the front of the body 10, the foreign matter is collected in the dust collecting bag (40). The air passing through the dust collecting bag 40 is sucked into the electric motor 50 through the through hole 62 of the partition 60 in the state in which dust is first filtered through the dust collecting filter 70 to protect the electric motor 50 and the like. . The exhausted air is purified in a state in which fine dust is secondarily filtered through the exhaust filter 80 and exhausted to the outside of the body 10 through the exhaust hole 14.
그러나 상기 작동에 따른 종래의 진공청소기는 배기공(14)이 대기 노출된 상태로 전동기(50)를 통과한 공기가 배기공(14)을 통해 화살표로 나타낸 바와 같이 일직선으로 빠르게 배기된다.However, the conventional vacuum cleaner according to the above operation, the air passing through the electric motor 50 while the exhaust hole 14 is exposed to the atmosphere is quickly exhausted in a straight line as indicated by the arrow through the exhaust hole 14.
이에 배기공(14)을 통과한 배기공기에 의해 배기공(14) 후방, 즉 청소기 몸체(10)후방의 청소바닥면에 놓인 이물질등이 날려 사용자에 불쾌감을 주며 호흡기 질환을 일으키는등 문제점이 있었다. 또한 배기필터(80)의 두께가 배기공기의 유로를 이룸으로써, 구조적으로 걸름기능이 미약한 것이다. 이러한 문제점은 청소기 몸체(10) 내부로 흡입된 공기를 정화된 상태로 배기하기 위한 배기필터(80)의 장착 목적에도 반하게 된다.Accordingly, foreign matters placed on the cleaning bottom surface of the rear of the exhaust hole 14, that is, behind the cleaner body 10 by the exhaust air passing through the exhaust hole 14 are blown off, causing inconvenience to the user and causing respiratory diseases. . In addition, since the thickness of the exhaust filter 80 constitutes the flow path of the exhaust air, the filtering function is structurally weak. This problem is also opposed to the purpose of mounting the exhaust filter 80 for exhausting the air sucked into the cleaner body 10 in a purified state.
다른 문제점은 배기필터(80)를 통과한 공기중 일부는 배기공(14)을 통해 직접 배기되나, 나머지 일부는 배기공(14)의 인접부위에 부딪치게 되어 소음원이 되는 것이다.Another problem is that some of the air passing through the exhaust filter 80 is directly exhausted through the exhaust hole 14, but the other part hits the adjacent portion of the exhaust hole 14 to become a noise source.
또 다른 문제점은 배기필터(80)를 몸체(10) 내부에 장착함으로써, 배기필터(80)의 교체 및 세척 작업이 번거로운 것이다. 아울러 구동실(30)이 협소공간을 형성하여 배기필터(80)의 착탈 작업이 더욱 어려운 것이다.Another problem is that by mounting the exhaust filter 80 inside the body 10, replacement and cleaning of the exhaust filter 80 is cumbersome. In addition, since the driving chamber 30 forms a narrow space, the detachable work of the exhaust filter 80 is more difficult.
이에 본 발명은 상기한 제반 문제점을 해결하기 위하여 창출한 것으로서, 본 발명의 목적은 배기공기를 원심방향으로 산포시켜 배기필터를 통과하는 배기공기의 유로를 길게하는 진공청소기용 배기필터의 고정장치를 제공하는 데 있다.Accordingly, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a device for fixing an exhaust filter for a vacuum cleaner that spreads exhaust air in a centrifugal direction and lengthens the flow path of the exhaust air passing through the exhaust filter. To provide.
본 발명의 다른 목적은 배기되는 공기의 저항에 따라 발생한 진동을 억제하는 배기필터의 고정장치를 제공하는 데 있다.Another object of the present invention is to provide an apparatus for fixing an exhaust filter which suppresses vibration generated by the resistance of the exhaust air.
본 발명의 또다른 목적은 배기필터의 착탈이 용이한 배기필터의 고정장치를 제공하는 데 있다.Still another object of the present invention is to provide a fixing device for the exhaust filter, which is easy to attach and detach the exhaust filter.
이와 같은 목적은 본 발명의 구성중 구동실에 내장한 전동기에서 고속으로 베기되는 배기공기를 대기로 배기하기 위하여 후면에 복수개의 배기공을 형성한 몸체와, 상기 몸체의 배기공과 대향하여 몸체 외부에 착탈 가능하게 대향하는 필터지지판과, 상기 필터지지판에 지지되어 배기공을 몸체 외부에서 차단하는 배기필터를 특징적 구성으로 하여, 상기 배기되는 공기의 직선흐름 및 배기공 인접부위의 유속마찰의한 진동이 필터지지판에 통제되고, 배기필터가 몸체외부에서 착탈가능 함으로써 실현할 수 있다.This object is a body formed with a plurality of exhaust holes in the rear to exhaust the exhaust air to be cut at a high speed in the motor of the drive chamber in the configuration of the present invention, and to the outside of the body facing the exhaust hole of the body A filter support plate that is detachably opposed to each other and an exhaust filter that is supported by the filter support plate to block the exhaust hole from outside the body, the linear flow of the exhausted air and the vibration of the flow rate friction of the adjacent portion of the exhaust hole Controlled by the filter support plate, the exhaust filter can be detachable from the outside of the body.
이하 첨부한 도면 제2도와 제3도를 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 2 and 3.
도면에서 본 발명에 적용한 진공청소기용 배기필터의 고정장치는 복수개의 배기공(140)을 형성한 몸체(100) 후면을 전동기(400)를 내장한 구동실(120) 측으로 절곡하여 함몰부(130)를 형성하고, 상기 배기공(140)을 몸체(100) 외부에서 배기필터(200)로 차단하며, 상기 배기필터(200)를 지지하여 몸체(100) 외부 후면에 착탈 가능하게 고정하는 필터지지판(300)으로 구성한다.In the drawings, the fixing device of the exhaust filter for the vacuum cleaner applied to the present invention is bent 130 by bending the back of the body 100 having the plurality of exhaust holes 140 toward the drive chamber 120 incorporating the electric motor 400. A filter support plate which forms a), blocks the exhaust hole 140 from the outside of the body 100 by the exhaust filter 200, and supports the exhaust filter 200 to be detachably fixed to the outer rear of the body 100. It consists of 300.
상기 필터지지판(300)의 고정은 필터지지판(300)에 복수개의 체결돌기(310)를 형성하고, 상기 체결돌기(310)에 대향하는 몸체(100) 이부 후면에 체결공(110)을 형성하여, 상기 체결공(110)에 체결돌기(310)를 끼워맞춤식으로 형합하여 이루어진다. 체결돌기(310) 및 체결공(110)은 형성면이 바뀌어도, 즉 체결돌기(310)를 몸체(100) 외부 후면에 형성하고 체결공(110)을 필터지지판(300)에 형성하여도 실시가 가능하다.The fixing of the filter support plate 300 forms a plurality of fastening protrusions 310 on the filter support plate 300, and forms a fastening hole 110 on a rear portion of the body 100 opposite to the fastening protrusion 310. The fitting protrusion 310 is formed by fitting to the fastening hole 110. The fastening protrusion 310 and the fastening hole 110 may be formed even if the forming surface is changed, that is, the fastening protrusion 310 is formed on the outer back of the body 100 and the fastening hole 110 is formed on the filter support plate 300. It is possible.
그리고 필터지지판(300)에는 배기필터(200)의 이탈방지 및 유동방지수단으로 체결돌기(310)에 인접하여 배기필터(200)의 테두리가 걸리는 걸림턱(320)을 복수개 형성하고, 배기필터(200)의 대향면에 배기필터(200)를 가압하는 누름돌기(330)를 복수개 형성한다.In addition, the filter support plate 300 is provided with a plurality of catching jaws 320, which are adjacent to the fastening protrusion 310, to which the edge of the exhaust filter 200 is caught, to prevent separation and flow of the exhaust filter 200. A plurality of push protrusions 330 for pressing the exhaust filter 200 are formed on the opposite surface of the 200.
아울러 배기공(140)을 통과한 배기공기가 함몰부(130)와 필터지지판(300) 사이로 원활히 배기되도록 함몰부(130)의 면적보다 필터지지판(300)의 면적을 보다 작게 형성함이 바람직하다.In addition, the area of the filter support plate 300 is preferably smaller than the area of the depression 130 so that the exhaust air passing through the exhaust hole 140 is smoothly exhausted between the depression 130 and the filter support plate 300. .
상기 구성에 의한 본 발명의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention by the above configuration is as follows.
필터지지판(300)은 제2도에 분해사시도로 나타낸 바와 같이 배기필터(200)를 지지하여 체결돌기(310)를 체결공(110)에 형합하여 몸체(100) 외부 후면에 고정한다.The filter support plate 300 supports the exhaust filter 200 as shown in the exploded perspective view in FIG. 2 to form the fastening protrusion 310 to the fastening hole 110 to be fixed to the outer rear of the body 100.
제3도에서, 배기필터(200)는 테두리 및 필터지지판(300)의 대향면이 각각 걸림턱(320) 및 누름돌기(330)에 가압되어 이탈 및 유동이 방지된 상태로 배기공(140)을 포함한 몸체(100)의 외부 후면 및 필터지지판(300)에 밀착되어 있다.In FIG. 3, the exhaust filter 200 has the exhaust hole 140 in a state where the opposite surfaces of the edge and the filter support plate 300 are pressed against the locking jaw 320 and the pressing protrusion 330, respectively, to prevent the separation and flow. It is in close contact with the outer back and the filter support plate 300 of the body 100, including.
이 상태에서 전동기(400)를 통해 고속으로 흡배기되는 공기는 복수개의 배기공(140)을 통해 배기필터(200)로 진입하여 미세먼지가 걸러진 상태로 일직선으로 진행한다. 이후 배기공기는 필터지지판(300)에 부딪쳐 유속이 저하된 상태로 원심방향으로 산포(散布)된후 함몰부(130)의 주변에 부딪쳐 유속이 다시한번 저하된 상태로 배기된다. 따라서 배기공(140) 후면, 즉 몸체(100) 외부 후면의 청소대상면에 놓인 이물질이 날리지 않게되어 사용자의 불쾌감등이 해소된다.In this state, the air intake and exhaust at high speed through the motor 400 enters the exhaust filter 200 through the plurality of exhaust holes 140 and proceeds in a straight line with fine dust filtered. Since the exhaust air hits the filter support plate 300 and is dispersed in the centrifugal direction in a state where the flow rate is lowered, the exhaust air hits the periphery of the recess 130 and is exhausted in the state where the flow rate is lowered again. Therefore, foreign matters placed on the rear surface of the exhaust hole 140, that is, the outer surface of the body 100, are not blown away, and thus discomfort of the user is eliminated.
아울러 원심방향으로 산포된 배기공기는 화살표로 나타낸 바와 같이 배기필터(200)내에서 배기유로를 길게 가짐으로써, 배기필터(200)의 걸림기능이 향상된다. 이에 배기공기는 완전히 정화된 상태로 배기된다.In addition, the exhaust air scattered in the centrifugal direction has a long exhaust passage in the exhaust filter 200 as indicated by the arrow, thereby improving the locking function of the exhaust filter 200. The exhaust air is exhausted in a completely purified state.
또한 고속으로 배기되는 공기중 배기공(140)의 인접부위, 즉 몸체(100) 내부 후면에 부딪쳐 발생하는 진동 및 소음은 필터지지판(300)이 배기필터(200)를 지지한 상태에서 몸체(100)에 고정됨으로써, 상기 필터지지판(300)이 몸체(100)의 떨림을 억제하고 소음원을 2중 차단하여 진동 및 소음을 억제하는 효과도 있다.In addition, the vibration and noise generated by hitting an adjacent portion of the exhaust hole 140 in the air, which is exhausted at a high speed, that is, the inner rear surface of the body 100 may be caused by the filter support plate 300 supporting the exhaust filter 200. By being fixed to the), the filter support plate 300 has an effect of suppressing the vibration of the body 100 and blocking the noise source twice to suppress vibration and noise.
그리고 필터지지판(300)의 착탈에 따라 몸체(100) 외부에서 배기필터(200)의 착탈이 이루어져, 배기필터(200)의 교체 및 세척이 용이한 효과도 있다.In addition, the detachment of the exhaust filter 200 is performed outside the body 100 according to the detachment of the filter support plate 300, so that the exhaust filter 200 may be easily replaced and cleaned.
아울러 배기필터(200)가 함몰부(130)내에 위치함으로써, 배기필터(200) 테두리가 대기에 노출되지 않아 청소기의 외적 미려함이 또한 있다.In addition, since the exhaust filter 200 is located in the recess 130, the edge of the exhaust filter 200 is not exposed to the atmosphere, and thus the external appearance of the cleaner is also beautiful.
한편 본 발명의 실예에에서 필터지지판(300)은 밀폐면으로 형성하였으나, 제품의 성능, 즉 전동기(400)의 구동에 따른 흡기압의 효율을 향상시키기 위하여 제4도에 나타낸 바와 같이 필터지지판(400)에 복수개의 통공(410)을 형성하여도 본 발명의 기술적 사상인 배기공기의 분산효과를 실현할 수 있다. 이때 복수개의 통공(410)을 몸체(100) 후면의 배기공(140)에 대하여 편심되도록 형성하여도 바람직하다.Meanwhile, in the exemplary embodiment of the present invention, the filter support plate 300 is formed as a closed surface, but as shown in FIG. 4 in order to improve the performance of the product, that is, the efficiency of intake pressure according to the driving of the electric motor 400 ( Even if the plurality of through holes 410 are formed in the 400, the dispersion effect of the exhaust air, which is the technical idea of the present invention, can be realized. In this case, the plurality of through holes 410 may be formed to be eccentric with respect to the exhaust hole 140 at the rear of the body 100.
상술한 바와 같이 본 발명에 의한 진공청소기용 배기필터의 고정장치는 배기필터의 착탈이 몸체 외부에서 이루어지고, 배기공기의 흐름 및 유속마찰에 의한 몸체의 진동이 필터지지판에 의해 통제됨으로써, 사용 및 신뢰감이 향상되는 유용한 발명이다.As described above, the fixing device of the exhaust filter for a vacuum cleaner according to the present invention is used by attaching and detaching the exhaust filter from the outside of the body, and the vibration of the body by the flow of the exhaust air and the flow rate friction is controlled by the filter support plate. It is a useful invention that improves the reliability.
