도 3은 본 발명의 바람직한 실시예에 따른 집진 블레이드와 먼지통의 분해 사시도이다.3 is an exploded perspective view of a dust collecting blade and a dust container according to a preferred embodiment of the present invention.
먼지통(100)의 전면 하부에는 쓰레기가 유입되도록 개방형성되는 유입구(106)가 구비된다. The lower portion of the front surface of the dust container 100 is provided with an inlet opening 106 is formed to open the waste.
먼지통(100)은 일측에 내부방향을 향해 오목한 요홈의 형태로 형성되는 후크 삽입홈(110)을 구비한다. 또한, 먼지통(100)의 타측에는 수직방향으로 돌출형성되는 힌지(120)가 구비된다. Dust bin 100 has a hook insertion groove 110 is formed in the form of a recess concave toward the inner direction on one side. In addition, the other side of the dust container 100 is provided with a hinge 120 protruding in the vertical direction.
상기 후크 삽입홈(110)과 힌지(120)는 먼지통(100)에 집진 블레이드(200)를 탈착시키기 위해 구비되는 것으로 후에 집진 블레이드(200)와 함께 상세하게 설명한다.The hook insertion groove 110 and the hinge 120 are provided to detach the dust collecting blade 200 in the dust container 100 will be described in detail later with the dust collecting blade 200.
먼지통(100)은 유입구(106)의 하부를 막도록 하부면으로부터 미리 정해진 높이만큼 돌출형성되는 흘림 방지판(124)을 구비한다. 상기 흘림 방지판(124)은 집진 블레이드(200)를 먼지통(100)에서 분리시킬 때 유입구(106)에 가까이 모여있는 분진 등의 쓰레기가 임의로 쏟아지게 되는 것을 방지하는 역할을 한다.The dust container 100 includes a spill prevention plate 124 protruding from the lower surface by a predetermined height so as to block the lower portion of the inlet 106. The spill prevention plate 124 serves to prevent the dust, such as dust, collected near the inlet 106 when the dust collecting blade 200 is separated from the dust container 100.
여기서 흘림 방지판(124)의 높이는 집진 블레이드(200)의 높이보다 작게 형성하여 먼지통(100) 내부로 쓰레기가 원활하게 유입될 수 있도록 한다.Here, the height of the spill prevention plate 124 is smaller than the height of the dust collecting blades 200 so that the waste can be smoothly introduced into the dust container (100).
집진 블레이드(200)는 유입구(106)의 전방에 장착된다. 이러한 집진 블레이드(200)는 브러쉬(2)의 회전에 의해 후방으로 이송되는 쓰레기가 먼지통(100) 내부로 유입되도록 가이드하는 역할을 한다.The dust collecting blade 200 is mounted in front of the inlet 106. The dust collecting blade 200 serves to guide the garbage transported to the rear by the rotation of the brush 2 to be introduced into the dust container 100.
도 4는 본 발명의 바람직한 실시예에 따른 집진 블레이드의 측면도이고, 도 5는 집진 블레이드가 변형된 상태를 도시한 도면이다.Figure 4 is a side view of the dust collecting blade according to a preferred embodiment of the present invention, Figure 5 is a view showing a state in which the dust collecting blade is deformed.
도 4에 도시된 바와 같이, 집진 블레이드(200)는 후면에 집진 블레이드(200)의 길이방향, 즉 횡방향을 따라 길게 형성되는 지지돌기(202)를 복수 개 구비한다.As illustrated in FIG. 4, the dust collecting blade 200 includes a plurality of support protrusions 202 formed on the rear surface of the dust collecting blade 200 in the longitudinal direction, that is, in the transverse direction.
집진 블레이드(200)는 청소 로봇(1)의 청소 도중 그 하단부가 솟아오른 바닥이나 바닥에 있는 장애물에 접하게 되면, 청소 로봇(1)의 주행에 방해되지 않도록 휘어져서 장애물 등을 통과할 수 있어야 한다.When the dust collecting blade 200 comes into contact with an obstacle on the floor or the bottom of which the lower end is raised during the cleaning of the cleaning robot 1, the dust collecting blade 200 should be bent so as not to interfere with the running of the cleaning robot 1 and pass through the obstacle. .
예를 들어, 청소 로봇(1)이 문턱을 넘거나 카펫 위를 이동하는 경우, 집진 블레이드(200)는 도 5에 도시된 바와 같이 바닥으로부터 솟아오른 문턱 또는 카펫과 같은 장애물에 접하더라도 주행방향의 반대방향으로 휘어지면서 장애물을 지나쳐갈 수 있도록 형성되어야 하는 것이다.For example, when the cleaning robot 1 moves over a threshold or moves on a carpet, the dust collecting blade 200 may be in a driving direction even if it encounters an obstacle such as a threshold raised from the floor or a carpet as shown in FIG. 5. It should be formed to be able to pass over obstacles while bending in the opposite direction.
그런데, 이와 같이 집진 블레이드(200)가 바닥에 접하여 휘어지게 되면 초기에는 집진 블레이드(200) 자체의 탄성에 의해 그 형태가 복원될 수 있으나, 이러한 휨이 반복될 경우에는 집진 블레이드(200)가 탄성을 잃고 영구적으로 변형된다. By the way, when the dust collecting blades 200 are bent in contact with the floor as described above, the shape may be restored by the elasticity of the dust collecting blades 200 itself, but when such bending is repeated, the dust collecting blades 200 may be elastic. Lose and become permanently deformed.
이렇게 되면, 브러쉬(2)와 집진 블레이드(200) 단부 사이의 거리가 멀어지게 되어 브러쉬(2)에 의해 후방으로 이송된 쓰레기를 먼지통(100) 내부로 유입시키는 것이 어렵게 되는 문제가 발생하게 된다. In this case, a distance between the brush 2 and the end of the dust collecting blade 200 becomes far, which causes a problem that it becomes difficult to introduce the waste transported backward by the brush 2 into the dust container 100.
상기 지지돌기(202)는 집진 블레이드(200)의 복원력을 향상시키고, 영구적 변형이 발생되는 것을 방지하여 장시간 동안 높은 청소효율이 지속되도록 하는 역할을 한다.The support protrusion 202 improves the restoring force of the dust collecting blade 200 and prevents permanent deformation from occurring, thereby maintaining a high cleaning efficiency for a long time.
바람직하게 복수 개 구비되는 지지돌기(202)는 상기 집진 블레이드(200)의 하단에 가깝게 배치되는 것일수록 직경이 작게 형성되도록 하여 더욱 원활하게 휘어질 수 있도록 한다.Preferably, the plurality of support protrusions 202 are provided to be closer to the lower end of the dust collecting blade 200, so that the diameter of the support protrusions 202 is formed to be more smoothly bent.
이러한 지지돌기(202)는 집진 블레이드(200)의 길이방향으로 형성됨에 따라 집진 블레이드(200)가 문턱이나 카펫 등을 용이하게 통과할 수 있도록 충분히 휘어지는 것이 가능하게 되는 것이다.As the support protrusion 202 is formed in the longitudinal direction of the dust collecting blades 200, the dust collecting blades 200 may be sufficiently curved to easily pass through the threshold or the carpet.
도 6은 집진 블레이드가 먼지통에 장착된 상태를 나타낸 사시도이고, 도 7은 먼지통에서 집진 블레이드를 분리하는 상태를 나타낸 사시도이다. 6 is a perspective view showing a state in which the dust collecting blade is mounted on the dust container, Figure 7 is a perspective view showing a state of separating the dust collecting blade from the dust container.
집진 블레이드(200)는 상기 후크 삽입홈(110)에 탈착되는 후크부(210)와 상기 힌지(120)에 결합되어 회동되는 회동부(220)를 구비한다.The dust collecting blade 200 includes a hook portion 210 detachably attached to the hook insertion groove 110 and a pivoting portion 220 coupled to the hinge 120 and rotated.
후크부(210)는 상기 후크 삽입홈(110)에 대응되도록 집진 블레이드(200)의 일측에 위치한다. 후크부(210)의 일단에는 후크 삽입홈(110)에 걸리도록 이루어지는 후크(212)가 형성된다. The hook portion 210 is positioned at one side of the dust collecting blade 200 to correspond to the hook insertion groove 110. One end of the hook portion 210 is formed with a hook 212 to be caught by the hook insertion groove (110).
상기와 같이 형성되는 후크(212)는 후크 삽입홈(110)에 걸리도록 탄지된 상태에서 소정의 힘을 가함으로써 상기 후크 삽입홈(110)에서 분리시킬 수 있도록 구비된다.The hook 212 formed as described above is provided to be separated from the hook insertion groove 110 by applying a predetermined force in a state of being striking to be caught by the hook insertion groove 110.
회동부(220)는 상기 힌지(120)의 위치에 대응되는 집진 블레이드(200)의 타측에 구비된다. 회동부(220)는 힌지(120)에 결합된 상태로 회동되어 유입구(106)를 개폐시키는 역할을 한다.The rotating part 220 is provided at the other side of the dust collecting blade 200 corresponding to the position of the hinge 120. Rotating portion 220 is rotated in a state coupled to the hinge 120 serves to open and close the inlet (106).
도 8은 회동부가 힌지에 결합되는 상태를 도시한 단면도이다.8 is a cross-sectional view showing a state in which the rotating unit is coupled to the hinge.
회동부(220)는 내주면이 상기 힌지(120)의 외주면에 접하도록 형성되는 힌지 삽입구(222)를 구비한다. 힌지 삽입구(222)는 힌지(120)에 결합 및 분리가 가능하도록 반원형이나 'c'자형으로 형성되는 것이 바람직하다.Rotating portion 220 has a hinge insertion hole 222 is formed so that the inner circumferential surface is in contact with the outer circumferential surface of the hinge 120. Hinge insertion hole 222 is preferably formed in a semi-circular or 'c' shape to be coupled to and detached from the hinge 120.
상기와 같이 힌지 삽입구(222)를 형성함으로써 도3에 도시된 바와 같이 집진 블레이드(200)를 먼지통(100)으로부터 완전히 분리시키는 것이 가능하게 되고, 이에 따라 집진 블레이드(200)가 손상되거나 수명이 다하게 되었을 경우 용이하게 교체할 수 있게 되는 것이다. 또한, 집진 블레이드(200)를 완전히 분리시킬 경우, 먼지통(100)의 내부를 더욱 용이하게 청소할 수 있게 된다.By forming the hinge insertion hole 222 as described above, it is possible to completely separate the dust collecting blade 200 from the dust container 100 as shown in Figure 3, thereby damaging the dust collection blade 200 or end of life. If you do it will be easy to replace. In addition, when the dust collecting blades 200 are completely separated, the inside of the dust container 100 may be more easily cleaned.
한편, 먼지통(100)은 힌지 삽입구(222)가 힌지(120)에 결합된 상태에서 상기 힌지 삽입구(222)의 외주면을 감싸도록 형성되는 분리 방지부(122)를 구비한다.On the other hand, the dust container 100 is provided with a separation prevention portion 122 formed to surround the outer circumferential surface of the hinge insertion hole 222 in a state in which the hinge insertion hole 222 is coupled to the hinge 120.
분리 방지부(122)는 힌지(120)에 결합된 힌지 삽입구(222)가 분리 방지부(122)와의 간섭을 피해 소정 각도 이상 회동되어야만 분리될 수 있도록 하는 역할을 한다.The separation prevention part 122 serves to allow the hinge insertion hole 222 coupled to the hinge 120 to be separated only when the hinge insertion hole 222 is rotated by a predetermined angle or more to avoid interference with the separation prevention part 122.
이러한 구성으로 인해, 후크부(210)가 후크 삽입홈(110)으로부터 분리된 상태에서도 힌지 삽입구(222)는 힌지(120)에 결합된 상태를 유지할 수 있게 되어 집진 블레이드(200)가 먼지통(100)에서 임의로 이탈되는 것을 방지하게 되는 것이다. Due to this configuration, even when the hook portion 210 is separated from the hook insertion groove 110, the hinge insertion hole 222 can maintain the state coupled to the hinge 120, so that the dust collecting blade 200 has the dust container 100. ) Will be prevented from leaving at random.
