도 2을 참조하면, 제2흡입체(220)는 경사진 제2피청소면(20)을 청소하기 위하여 제1흡입체(210)에 회전가능하게 관절 결합된다. 이를 위해, 제1흡입체(210)에는 힌지홈(211)이 형성되며, 제2흡입체(220)에는 힌지홈(211)에 삽입되기 위한 힌지돌기(221)가 형성된다. 그리고, 이러한 힌지홈(211) 및 힌지돌기(221)를 결합하기 위한 힌지핀(230)과, 힌지핀(230)에 설치된 탄성부재(240)가 필요하게 된다.Referring to FIG. 2, the second suction body 220 is rotatably articulated to the first suction body 210 to clean the inclined second cleaning surface 20. To this end, a hinge groove 211 is formed in the first suction body 210, and a hinge protrusion 221 for insertion into the hinge groove 211 is formed in the second suction body 220. Then, a hinge pin 230 for coupling the hinge groove 211 and the hinge protrusion 221, and the elastic member 240 installed on the hinge pin 230 is required.

이러한 힌지홈(211)을 형성하기 위해 제1흡입체(210)의 상면 우측에는 힌지핀(230)이 관통되기 위한 구멍이 뚫린 2개의 지지물(211a, 211b)이 제1흡입체(210)와 일체 또는 별개로 제작되어 설치된다.In order to form the hinge groove 211, two supports 211a and 211b having holes for penetrating the hinge pins 230 are formed on the upper right side of the first suction body 210 and the first suction body 210. It is manufactured and installed separately or separately.

힌지돌기(221)은 힌지홈(211)에 삽입되기 위해 제2흡입체(220)의 상면 좌측에 제2흡입체(220)와 일체 또는 별개로 제작되어 설치된 돌기로서, 돌기의 좌우측면에는 힌지핀(230)이 관통되기 위한 구멍이 뚫려있다.The hinge protrusion 221 is a protrusion formed integrally or separately from the second suction body 220 on the upper left side of the second suction body 220 so as to be inserted into the hinge groove 211, and hinges on the left and right sides of the protrusion. The hole for the pin 230 to penetrate is drilled.

힌지핀(230)은 힌지홈(211)에 힌지돌기(221)를 회전가능하게 결합시키기 위한 축으로서, 지지물(211a, 211b)의 구멍과 힌지돌기(221)의 구멍을 차례로 관통한다.The hinge pin 230 is an axis for rotatably coupling the hinge protrusion 221 to the hinge groove 211, and sequentially passes through the holes of the supports 211a and 211b and the holes of the hinge protrusion 221.

힌지핀(230)에는 코일스프링 같은 탄성부재(240)가 설치된다. 이러한 탄성부재(240)는 제2흡입체(220)를 항상 화살표 B방향(도 1참조)으로 가압하도록 설치된다. 따라서 제1피청소면(10)과 제2피청소면(20)이 평탄하여 경사각(θ1)이 0도일 경우, 탄성부재(240)에 의해 제1흡입체(210)와 제2흡입체(220)의 내각(θ2)이 자동적으로 180도가 되어, 제2흡입체(220)는 제1흡입체(210)에 대하여 수평으로 펴지게 된다. 그리고, 내각(θ2)이 0도가 되면 제2흡입체(220)가 제1흡입체(210)에 포개진 다.The hinge pin 230 is provided with an elastic member 240 such as a coil spring. The elastic member 240 is installed to always press the second suction body 220 in the direction of the arrow B (see Fig. 1). Therefore, when the first cleaning surface 10 and the second cleaning surface 20 are flat and the inclination angle θ1 is 0 degrees, the first suction body 210 and the second suction body 220 are formed by the elastic member 240. The inner angle (θ2) of the automatically becomes 180 degrees, the second suction body 220 is spread out horizontally with respect to the first suction body (210). When the internal angle θ2 is 0 degrees, the second suction body 220 overlaps the first suction body 210.

상기와 같은 제1흡입체(210)와 제2흡입체(220)의 결합구조에 의해 사용자는 제1피청소면(10)과 경사진 제2피청소면(20)을 동시에 청소할 수 있다. 보다 구체적인 청소방법을 설명하면 다음과 같다.By the coupling structure of the first suction body 210 and the second suction body 220 as described above, the user can simultaneously clean the first cleaning surface 10 and the inclined second cleaning surface 20. More specific cleaning method is as follows.

도 1을 참조하면, 제1피청소면(10)에 대한 제2피청소면(20)의 경사각(θ1)이 크면, 사용자는 연장관(140)을 화살표 F1방향으로 밀어 흡입구조립체(200)를 화살표 F2방향으로 전진시킨다. 이때 제2흡입체(220)는 사용자의 미는 힘에 의해 화살표 A방향으로 이동하면서 내각(θ2)이 작아진다.Referring to FIG. 1, when the inclination angle θ1 of the second cleaning surface 20 with respect to the first cleaning surface 10 is large, the user pushes the extension tube 140 in the direction of arrow F1 to move the suction assembly 200 to the arrow F2. Advance in the direction. At this time, the second suction body 220 is moved in the direction of the arrow A by the pushing force of the user, the inside angle (θ2) is reduced.

반면, 제1피청소면(10)에 대한 제2피청소면(20)의 경사각(θ1)가 작으면, 사용자는 연장관(140)을 화살표 F3방향으로 당겨 제1흡입체(210)를 화살표 F4방향으로 후진시킨다. 이때 제2흡입체(220)는 탄성부재(240)의 힘에 의해 화살표 B방향으로 이동하면서 내각(θ2)이 커진다.On the other hand, if the inclination angle θ1 of the second cleaning surface 20 with respect to the first cleaning surface 10 is small, the user pulls the extension tube 140 in the direction of arrow F3 and pulls the first suction body 210 in the direction of arrow F4. Rewind to At this time, the second suction body 220 is moved in the direction of the arrow B by the force of the elastic member 240, the inner angle (θ2) is increased.

이러한 방식에 의해 경사각(θ1)에 따라 제1흡입체(210)와 제2흡입체(220) 사이의 내각(θ2)이 가변되고, 이렇게 내각(θ2)이 가변됨에 따라 제1피청소면(10)에 제1흡입체(210)를 밀착하면서, 제2피청소면(20)에 제2흡입체(220)를 밀착시킬 수 있다. 따라서 청소기의 흡입성능이 그대로 유지되며, 청소도중 흡입구조립체(200)가 피청소면(10,20)과 충돌되어 손상되는 것이 방지된다. In this manner, the inner angle θ2 between the first suction body 210 and the second suction body 220 is variable according to the inclination angle θ1, and as the internal angle θ2 is thus changed, the first cleaning surface 10 is changed. The second suction body 220 may be brought into close contact with the second cleaning surface 20 while the first suction body 210 is in close contact with the first suction body 210. Accordingly, the suction performance of the cleaner is maintained as it is, and the suction structure assembly 200 is prevented from being damaged by colliding with the surfaces to be cleaned 10 and 20 during cleaning.

이하, 도 1에 도시된 흡입구조립체(200)의 동작을 설명하면 다음과 같다.Hereinafter, the operation of the suction structure assembly 200 shown in FIG. 1 will be described.

도 1 및 도 2를 참조하면, 사용자는 제1피청소면(10)과 제2피청소면(20)을 동시에 청소하기 위하여 경사각(θ1)에 따라 내각(θ2)을 가변시킨다. 이를 위해 연장관(140)을 화살표 F1방향으로 민다. 이 경우 제1흡입체(210)는 제1피청소면(10)과 접촉하면서 화살표 F2방향으로 전진하고, 제2흡입체(220)는 화살표 A방향으로 회전하면서 제2피청소면(20)에 접촉하게 된다. 이렇게 제1흡입체(210)가 제1피청소면(10)에 접촉되고 제2흡입체(220)가 제2피청소면(20)에 접촉된 상태에서 흡입구조립체(200)를 화살표 E나 F방향으로 움직이면서 제1피청소면(10)과 제2피청소면(20)을 청소한다.1 and 2, the user changes the inner angle θ2 according to the inclination angle θ1 to simultaneously clean the first and second cleaned surfaces 10 and 20. To this end, the extension pipe 140 is pushed in the direction of the arrow F1. In this case, the first suction body 210 moves forward in the direction of arrow F2 while contacting the first cleaning surface 10, and the second suction body 220 contacts the second cleaning surface 20 while rotating in the direction of arrow A. FIG. Done. The suction structure assembly 200 moves in the direction of the arrow E or F while the first suction body 210 is in contact with the first cleaning surface 10 and the second suction body 220 is in contact with the second cleaning surface 20. The first cleaning surface 10 and the second cleaning surface 20 are cleaned while moving to.

이때, 제1흡입공(212)의 외곽에 설치된 청소모(250)에 의해 제1피청소면(10)에 고착된 먼지가 타격 및 스크래치 되어서 분리되며, 이렇게 분리된 먼지와 제1피청소면(10)의 먼지는 제1흡입체(210)의 하면에 형성된 제1흡입공(212)을 거쳐 흡입통로(213)에 모이게 된다.At this time, the dust adhered to the first cleaning surface 10 by the cleaning cap 250 installed on the outside of the first suction hole 212 is separated by hitting and scratching, the separated dust and the first cleaning surface (10) Dust is collected in the suction passage 213 via the first suction hole 212 formed on the lower surface of the first suction body 210.

또한, 제2흡입공(222)의 외곽에 설치된 청소모(250)에 의해 제2피청소면(20)에 고착된 먼지가 타격 및 스크래치 되어서 분리되며, 이렇게 분리된 먼지와 제2피청소면(20)의 먼지는 제2흡입체(220)의 하면에 형성된 제2흡입공(222)과 이와 연통된 제1흡입공(212)을 거쳐 흡입통로(213)에 모이게 된다.In addition, the dust adhered to the second cleaning surface 20 by the cleaning cap 250 installed on the outer side of the second suction hole 222 is separated by hitting and scratching, the separated dust and the second cleaning surface 20 Dust is collected in the suction passage 213 through the second suction hole 222 formed on the lower surface of the second suction body 220 and the first suction hole 212 communicated with the second suction hole 222.

이후, 흡입통로(213)에 모인 먼지는 연장관(140), 플랙스블호스(120)를 거쳐 청소기본체(110)내의 오물수거실(미도시)에 집진되게 된다.Thereafter, the dust collected in the suction passage 213 is collected in the waste collection chamber (not shown) in the cleaning main body 110 through the extension pipe 140 and the flexible hose 120.

한편, 흡입구조립체(300)를 도 3에 도시된 바와 같이 계단청소전용으로 구성할 수 있다. 여기서 도면부호 400은 계단(300)에 깔려있는 카페트를 나타낸다.On the other hand, the suction assembly 300 can be configured for stair cleaning only, as shown in FIG. Here, reference numeral 400 denotes a carpet laid on the stairs 300.

흡입구조립체(300)를 계단청소전용으로 구성할 경우 제1흡입체(310)와 제2흡입체(320)가 이루는 내각(θ4)은 항상 60도이상인 것이 바람직하다. 보다 바람직하 게는 90도로 고정하는 것이 더 좋다. 이를 위해 제1흡입체(310)의 우측모서리(310a, 도 4참조)와 제2흡입체(320)의 좌측모서리(320b, 도 4 참조)를 상호 접촉시킨다. 이렇게 90도로 고정시키는 이유는, 제1피청소면(30)과 제2피청소면(40)의 경사각(θ3)이 항상 90도이므로, 청소시에는 내각(θ4)이 가변될 필요가 없기 때문이다. 같은 이유로, 흡입구조립체(300)가 계단청소전용으로 사용될 경우에는 흡입구조립체(300)에 내각(θ4)을 자동적으로 조절해 주는 탄성부재(240, 도 2참조)가 필요없게 된다.When the suction structure assembly 300 is configured for stair cleaning only, the inner angle θ4 formed by the first suction body 310 and the second suction body 320 is always 60 degrees or more. More preferably, it is better to fix it at 90 degrees. To this end, the right edge 310a (see FIG. 4) of the first suction body 310 and the left edge 320b (see FIG. 4) of the second suction body 320 are brought into contact with each other. The reason for fixing it at 90 degrees is because the inclination angle θ3 of the first to-be-cleaned surface 30 and the second to-be-cleaned surface 40 is always 90 degrees, and thus the inner angle θ4 does not need to be changed during cleaning. For the same reason, when the suction assembly 300 is used exclusively for stair cleaning, there is no need for an elastic member 240 (see FIG. 2) that automatically adjusts the inner angle θ4 to the suction assembly 300.

그리고, 내각(θ4)이 90도로 고정될 경우, 도 4와 같이 제2흡입체(320)를 제1흡입체(310)방향으로 90도 회전시켜 제1흡입체(310)에 포개지도록 하여, 흡입구조립체(300)의 보관상 편리함을 기할 수 있다. 이 밖의 구성은 도 1에 도시된 흡입구조립체(200)과 동일하므로 설명을 생략한다.When the internal angle θ4 is fixed at 90 degrees, the second suction body 320 is rotated 90 degrees in the direction of the first suction body 310 to be superimposed on the first suction body 310 as shown in FIG. 4. Convenience in storage of the suction assembly 300 can be provided. Since the other configuration is the same as the suction structure assembly 200 shown in FIG. 1, description thereof will be omitted.

이하, 도 3에 도시된 흡입구조립체(300)의 동작을 설명하면 다음과 같다.Hereinafter, the operation of the suction structure assembly 300 shown in FIG. 3 will be described.

도 3을 참조하면, 사용자는 제1피청소면(30)과 제2피청소면(40)을 동시에 청소하기 위하여 제1흡입체(310)를 제1피청소면(30)에, 제2흡입체(320)를 제2피청소면(30)에 각각 접촉시킨다. 이 경우, 도 1 및 도 2의 구성을 가진 흡입구조립체(200)와 달리 경사각(θ3)과 내각(θ4)이 90도로 고정된 관계로, 경사각(θ3)에 따라 내각(θ4)을 가변시키기 위해 연장관(140)에 별도의 힘을 가할 필요가 없다.Referring to FIG. 3, in order to simultaneously clean the first cleaning surface 30 and the second cleaning surface 40, the user may attach the first suction body 310 to the first cleaning surface 30 and the second suction body ( 320 is in contact with the second cleaning surface 30, respectively. In this case, unlike the suction structural assembly 200 having the configuration of FIGS. 1 and 2, the inclination angle θ3 and the internal angle θ4 are fixed at 90 degrees, so that the internal angle θ4 may be changed according to the inclination angle θ3. It is not necessary to apply a separate force to the extension tube 140.

이렇게 제1흡입체(310)가 제1피청소면(30)에 접촉되고 제2흡입체(320)가 제2피청소면(40)에 접촉된 상태에서 흡입구조립체(300)를 화살표 G나 H방향으로 움직이면서 제1피청소면(30)과 제2피청소면(40)을 청소한다. 이후 과정은 도 1 및 도 2 의 구성을 가진 흡입구조립체(200)와 동일하므로 설명을 생략하기로 한다.The first suction body 310 is in contact with the first cleaning surface 30 and the second suction body 320 is in contact with the second cleaning surface 40. The first cleaning surface 30 and the second cleaning surface 40 are cleaned while moving to. Since the process is the same as the suction structure assembly 200 having the configuration of Figures 1 and 2 will not be described.

이상에서 설명한 바와 같은 진공청소기의 흡입구조립체의 실시예에 따르면, 피청소면이 경사각을 가지더라도 편리하게 청소할 수 있으며, 청소기의 흡입성능이 그대로 유지되며, 청소도중 흡입구조립체가 피청소면과 충돌되어 손상되는 것이 방지된다.According to the embodiment of the suction structure assembly of the vacuum cleaner as described above, even if the surface to be cleaned has an inclination angle, it can be conveniently cleaned, the suction performance of the vacuum cleaner is maintained as it is, and the cleaning structure collides with the surface to be cleaned during cleaning. Is prevented.

상기와 같은 효과는 특히, 피청소면의 경사각이 90도인 계단을 청소하는 경우와, 계단에 먼지가 쉽게 쌓일 수 있는 카펫트가 깔려 있어 그 청소주기가 짧은 경우에 더 크다.The above effects are particularly great when cleaning a staircase with an inclination angle of the surface to be cleaned 90 degrees, and when the cleaning cycle is short because the carpet is easily piled up with dust.
