본 발명은 진공청소기의 배기구조에 관한 것으로, 특히 배출공기를 방사상으로 분산시키어 필터통과 거리를 증대시킴과 아울러, 후풍감속과 배기음을 감소시킬 수 있게한 진공청소기의 배기구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust structure of a vacuum cleaner, and more particularly, to an exhaust structure of a vacuum cleaner in which exhaust air is radially dispersed to increase a filter passage distance, and to reduce postwind reduction and exhaust sound.
진공청소기는 대체적으로 흡입펌프가 내장된 본체와 연결호우스로 하여 연이어지는 연결파이프의 선단부에 흡입구를 설치하고, 이의 흡입구를 통해 청소바닥면의 먼지나 이물을 흡입식으로 필터봉지내로 집진시키고 흡입공기는 별도의 배기경로를 토해 대기로 배출되게 하고 있다.In general, the vacuum cleaner is composed of a main body with a suction pump and a connection hose, and a suction port is installed at the front end of the connecting pipe, and dust or foreign matter on the bottom of the cleaning floor is suction-collected into the filter bag through the suction port. The gas is discharged to the atmosphere through a separate exhaust path.
그러한 진공청소기에서 청소바닥면의 흡입시 먼지나 이물을 빨아들인 흡인공기의 배출과정을 설명하면 제1도 및 제2도에서와 같이 본체(10)내 전방측에 읍입경로와 연이어지고 삽탁식으로 설치되는 필터봉지(20)내로 먼지와 이물이 함께 운반되어 흡입되고 이렇게 필터봉지(20)내로 흡입된 흡입공기는 필터봉지(20)내에서 먼지와 이물들과 분리되며 직후방의 흡입펌프(30)로 하여 필터(50)를 거친후 본체(10) 후면 하부측에 구비되는 배출공(40)를 통하여 대기로 배출되게 하고 있다.In the vacuum cleaner, the process of discharging the suction air that sucks in the dust or foreign matter during suction of the cleaning floor surface is connected to the entrance path in front of the main body 10 as shown in FIGS. 1 and 2. Dust and foreign matter are transported together and sucked into the filter bag 20 to be installed. The suction air sucked into the filter bag 20 is separated from the dust and foreign matter in the filter bag 20 and the suction pump 30 immediately afterwards. After passing through the filter 50 to the exhaust through the discharge hole 40 provided in the lower back side of the main body 10 to be discharged to the atmosphere.
그런데 이러한 흡인공기는 배출시 그 후풍이 청소기 본체의 후방에서 크게 작용하는, 즉 먼지나 이물의 원격흡인을 위해 적당한 흡입출력을 가지는 흡입펌프(30)로 흡인된 흡인공기는 필터(50)를 통과하면서 흡인공기내에 함유된 분진을 여과시키고 이렇게 정화된 순수한 흡인공기만을 배출공(40)을 통해 대기로 배출되게 하고 있는데, 이때 배출공(40) 직전방에서 필터(50)를 통과하나 배기 송풍력은 크게 완화되지 않은 상태에서 그대로 배출공(40)을 통해 대기로 배기되고 있다. 이러한 배기송풍력은 본체의 후풍을 크게 작용시키고 그 흡인공기의배출소음을 크게 일으키게 되어 청소시 소음공해등의 사용상에 많은 불편을 주고 있는 문제점이 있었다.However, when the suction air is discharged, the suction air acts largely at the rear of the cleaner body, that is, the suction air sucked into the suction pump 30 having a proper suction output for remote suction of dust or foreign matter passes through the filter 50. While the dust contained in the suction air is filtered and only the pure suction air thus purified is discharged to the atmosphere through the discharge hole 40. At this time, the filter 50 is directly passed through the discharge hole 40, but the exhaust blowing force Is exhausted to the atmosphere through the discharge hole 40 as it is not largely relaxed. Such exhaust blowing force acts to greatly increase the rear wind of the main body, and causes a large amount of exhaust noise of the suction air, which causes a lot of inconveniences in use such as noise pollution during cleaning.
또 본체(10)의 흡인공기 배기를 위한 배출공(40)이 제1도에서와 같이 구조적으로 본체(10)의 후면 하부측에 위치되고 있는데, 이렇게 본체(10) 후면의 하부측에 위치한 배출공(40)을 통해 대기로 배출되는 흡인공기는 청소바닥면에 근접되게 송풍력이 작용하여 그 청소바닥면의 먼지나 이물을 비산시키고, 이러한 먼지의 비산은 불쾌감은 물론 비위생적이로 청소성을 떨어뜨리게 되는 문제점을 주고 있다.In addition, the exhaust hole 40 for the suction air exhaust of the main body 10 is structurally located on the lower rear side of the main body 10, as shown in FIG. The suction air discharged to the atmosphere through the ball 40 acts as a blowing force close to the cleaning floor surface to scatter dust or foreign matter on the cleaning floor surface, and the scattering of such dust is unpleasant as well as unsanitary. Giving problems dropped.
본 발명의 목적은 상기와 같은 사정을 고려하여 이루어진 것으로, 그 목적은 배기소음을 최소로 줄이고 여과필터의 정화능력을 극대화하고 청소바닥면의 먼지나 이물의 비산을 방지시키어 위생적이고도 청소성을 향상시킬 수 있게한 진공청소기의 배기구조를 제공하는 것이다.The object of the present invention has been made in consideration of the above circumstances, the object of which is to minimize the exhaust noise, to maximize the purifying capacity of the filter and to prevent the dust or foreign matters from the cleaning floor surface to improve hygienic and cleanability It is to provide an exhaust structure of the vacuum cleaner that allows.
본 발명의 다른 목적은 배출공이 노출되지 않게 하여 본체 후방의 외관성은 물론 제품성을 향상시킬 수 있게한 진공청소기의 배기구조를 제공함에 있다.It is another object of the present invention to provide an exhaust structure of a vacuum cleaner that prevents the discharge hole from being exposed, thereby improving the appearance as well as the productability behind the main body.
이러한 본 발명의 목적은 진공청소기의 구동시 본체 후방으로 배출하는 흡인공기 배기구조를 제공함에 의해 달성되게 되는데, 이 배기구조를 청소기 본체의 후면에 흡입펌프 직후방으로 연어지는 배기공을 구비하고 있고, 상기 배기공의 크기는 청소기 본체의 전체 또는 일부분을 차지할 수 있다. 이러한 배기공내에는 그 배기공내경 보다는 다소적은 외경을 가지고 배기공 내주연으로 배기통로가 제공되도록한 배기공덮개가 결속봉과 삽입보스에 의해 착탈식으로 설치된다. 배기공덮개 내측 주벽면에는 또한 배기되는 흡인공기에 함유된 분진을 걸러내는 여과필터를 적어도 하나이상 다중적으로 설치하고 배기가 여과필터내에서의 통과거리를 길게 하도록 구성되어 있다. 따라서 배출음을 최소로 줄이고 청소바닥면 먼지의 비산을 방지하게 된다.The object of the present invention is achieved by providing a suction air exhaust structure for discharging to the rear of the main body when the vacuum cleaner is driven. The exhaust structure is provided with an exhaust hole which is opened immediately after the suction pump on the rear surface of the cleaner main body. The size of the exhaust hole may occupy the whole or part of the cleaner body. In the exhaust hole, an exhaust hole cover having a smaller outer diameter than that of the exhaust hole and having an exhaust passage provided at an inner circumference of the exhaust hole is detachably installed by a binding rod and an insertion boss. The inner circumferential wall of the exhaust hole cover is also configured to provide at least one or more filtration filters that filter out the dust contained in the suction air to be exhausted, and to exhaust the exhaust passage in the filtration filter. This minimizes the discharge noise and prevents the dust from scattering on the floor.
