본 발명은 업라이트형 진공청소기의 흡입구체에 관한 것으로, 특히 프론트 휠 캐리지의 처짐방지기능을 구비한 흡입구체에 관한 것이다.The present invention relates to a suction inlet of an upright vacuum cleaner, and more particularly to a suction inlet having a deflection prevention function of a front wheel carriage.

일반적으로 업라이트형 진공청소기는, 흡입력을 발생시키는 구동모터가 구비된 청소기본체와, 청소기본체의 하측에 소정각도 회동 가능하게 설치되는 흡입구체를 구비한다. 이와 같은 청소기본체 내에는 필터링수단과 오물수거통 등이 구비된다. 구동모터의 흡입력에 의해 흡입구체를 통해 흡입된 이물질은 필터링수단에 의해 필터링된 뒤, 오물수거통에 수거된다. 또한, 상기 청소기본체의 상부에는 온/오프 스위치가 마련된 손잡이가 마련된다. 따라서, 사용자는 손잡이를 잡고 피청소면을 따라 청소기를 이동시키면서 청소를 하게 되면, 흡입구체를 통해 피청소면의 먼지나 이물질 등이 빨려 들어와 제거된다.In general, the upright vacuum cleaner includes a cleaning main body provided with a drive motor for generating a suction force, and a suction inlet body rotatably provided at a predetermined angle under the cleaning main body. Such a cleaning body is provided with a filtering means and a waste container. The foreign matter sucked through the suction port by the suction force of the drive motor is filtered by the filtering means and collected in the waste container. In addition, a handle provided with an on / off switch is provided on the cleaning main body. Therefore, when the user cleans while holding the handle and moves the cleaner along the surface to be cleaned, dust or foreign matter on the surface to be cleaned is sucked in and removed through the suction port.

이러한 업라이트형 진공청소기에는 흡입브러시와 피청소면 사이의 높이를 조절하기 위한 장치가 구비되어 있는데, 이러한 노브형 높이조절 장치를 갖는 진공청소기가 대한민국 등록특허 제500846호에 개시된 바 있다.The upright type vacuum cleaner is provided with a device for adjusting the height between the suction brush and the surface to be cleaned, and the vacuum cleaner having such a knob type height adjusting device has been disclosed in Korean Patent No. 500846.

이러한 종래의 업라이트형 진공청소기는, 높이조절 노브의 회전이 피청소면의 상태에 따라 단계별로 구분되기 때문에 보다 다양한 청소면, 예컨대 털이 긴 카페트에서 짧은 털의 카페트까지 간편하게 청소작업을 수행할 수 있다. Such a conventional upright vacuum cleaner, since the rotation of the height adjustment knob is divided step by step according to the state of the surface to be cleaned, it is possible to perform a cleaning operation from a variety of cleaning surfaces, such as long hair carpet to short hair carpet easily.

이와 같은 업라이트형 진공청소기의 흡입구체의 높이를 조절할 경우, 사용자 는 노브를 돌려 원하는 위치에 설정하면, 캠의 위치가 결정됨에 따라 프론트 휠 캐리지의 경사가 위치가 결정된다. 이와 동시에, 프론트 휠 캐리지는 흡입구체 후방 양측에 결합된 메인 휠을 중심으로 회전브러시측이 소정각도로 승강함에 따라 흡입구체 전방에 결합된 회전브러시와 피청소면간의 이격거리가 조절된다.When adjusting the height of the suction port of the upright vacuum cleaner, the user sets the knob to a desired position, and the inclination of the front wheel carriage is determined according to the cam position. At the same time, the front wheel carriage adjusts the separation distance between the rotating brush coupled to the front of the suction port and the surface to be cleaned as the rotating brush side moves up and down at a predetermined angle around the main wheels coupled to both sides of the rear of the suction port.

한편, 사용자가 상기와 같은 업라이트형 진공청소기를 들어 올린 상태로 이동할 때, 프론트 휠 캐리지는 프론트 휠이 결합된 전방이 프로트 휠 캐리지의 힌지 결합부를 중심으로 자중에 의해 중력방향으로 회전한다. 이 때, 프론트 휠 캐리지는 프론트 휠 캐리지의 전방에 인접한 흡입구체의 하부에 형성된 소정의 걸림돌기에 흡입구체로부터의 이탈이 방지된다.On the other hand, when the user moves in the state of lifting the upright type vacuum cleaner as described above, the front wheel carriage is rotated in the direction of gravity by its own weight around the hinge coupling portion of the front wheel carriage is coupled to the front wheel carriage. At this time, the front wheel carriage is prevented from being separated from the suction port by a predetermined locking projection formed on the lower portion of the suction port adjacent to the front of the front wheel carriage.

하지만, 프론트 휠 캐리지는 걸림돌기에 의해 전방이 하방향으로 소정 각도로 쳐진 위치에 설정하게 됨에 따라, 흡입구체의 저면보다 더 아래로 돌출된 상태를 유지하게 된다. 따라서, 진공청소기를 다소 낮게 들어 올린 상태로 이동할 경우, 문턱이나 바닥에 놓여있는 각종 물건 들과 충돌하기 쉽고, 이로 인해 프론트 휠 캐리지가 파손되는 문제점이 있었다.However, as the front wheel carriage is set at a position in which the front is struck at a predetermined angle in the downward direction by the locking protrusion, the front wheel carriage is maintained to protrude further below the bottom surface of the suction port. Therefore, when the vacuum cleaner is moved to a slightly lower state, it is easy to collide with various objects placed on the threshold or the floor, which causes a problem that the front wheel carriage is broken.

상기 문제점을 해결하기 위해 본 발명은 업라이트형 진공청소기를 들어올린 상태로 이동 시, 흡입구체의 프론트 휠 캐리지의 처짐을 방지할 수 있는 업라이트형 진공청소기의 흡입구체를 제공하는 데 그 목적이 있다.In order to solve the above problems, an object of the present invention is to provide an inlet body of an upright vacuum cleaner which can prevent sagging of the front wheel carriage of the inlet body when the upright vacuum cleaner moves in a lifted state.

상기와 같은 목적을 달성하기 위해, 본 발명은 높이조절장치를 구비하고, 상 기 높이조절장치와 연동하여 수평 또는 경사설정됨에 따라 흡입구체의 높이를 변경 설정하는 프론트 휠 캐리지를 구비한 업라이트형 진공청소기의 흡입구체에 있어서, 상기 흡입구체에 힌지 결합되는 프론트 휠 캐리지가 자중에 의해 일측이 중력방향으로 선회하는 것을 억제하도록, 상기 흡입구체 저면에 돌출 형성되어 상기 프론트 휠 캐리지의 후방을 지지하는 처짐방지돌기를 포함하는 것을 특징으로 하는흡입구체를 제공한다. In order to achieve the above object, the present invention is provided with a height adjusting device, upright type vacuum having a front wheel carriage for changing the setting of the height of the suction inlet according to the horizontal or inclined set in conjunction with the height adjusting device. In the suction inlet of the vacuum cleaner, a front wheel carriage hinged to the suction inlet body is formed to protrude on the bottom surface of the inlet body so as to prevent the one side from turning in the gravity direction by its own weight, and sags supporting the rear of the front wheel carriage. It provides a suction sphere comprising a prevention projection.

상기 처짐방지돌기에는, 상기 프론트 휠 캐리지의 힌지축이 결합되는 결합부가 형성될 수 있다.The deflection preventing protrusion may be provided with a coupling portion to which the hinge shaft of the front wheel carriage is coupled.

상기 프론트 휠 캐리지의 후방은 상기 힌지축보다 더 돌출되어, 흡입구체가 바닥으로부터 들어 올려졌을 때, 상기 프론트 휠 캐리지의 후방이 상기 처짐방지돌기에 가압 접촉됨에 따라 프론트 휠 캐리지의 전방이 상기 흡입구체의 저면보다 더 돌출되는 것을 방지할 수 있다.The rear of the front wheel carriage protrudes more than the hinge axis, so that when the inlet port is lifted from the floor, the front of the front wheel carriage is brought into contact with the deflection protrusion as the rear of the front wheel carriage is pressed against the deflection protrusion. It can prevent protruding more than the bottom.

상기 프론트 휠 캐리지는 후방의 상측 모서리부에 만곡부가 형성되며, 상기 높이조절장치를 통해 상기 흡입구체의 높이를 상승시킬 때, 상기 프론트 휠 캐리지의 후방이 상기 처짐방지돌기에 대항하여 장력이 발생된 상태로 강제 피봇될 수 있다.The front wheel carriage is formed with a curved portion at the upper edge of the rear, when the height of the suction inlet through the height adjustment device, the rear of the front wheel carriage is generated tension against the deflection prevention projections Can be forced to a state.

이와 같이 구성된 본 발명의 일 실시예에 따른 흡입구체의 프론트 휠 캐리지의 처짐을 방지하는 작용을 도면을 참고하여 설명하면 다음과 같다. 도 5 및 도 6은 흡입구체의 승하강에 따른 프론트휠 캐리지의 수평상태와 경사상태를 각각 나타내는 개략측면도이고, 도 7은 업라이트형 진공청소기를 들어올릴 경우, 흡입구체의 프론트휠 캐리지가 처짐방지돌기에 의해 처침이 방지된 상태를 나타내는 개략측면도이다.Referring to the drawings to explain the action of preventing the deflection of the front wheel carriage of the suction in accordance with an embodiment of the present invention configured as described above as follows. 5 and 6 are schematic side views respectively showing a horizontal state and an inclined state of the front wheel carriage according to the rising and lowering of the suction inlet, and FIG. 7 is a front wheel carriage of the suction inlet when the upright vacuum cleaner is lifted. It is a schematic side view which shows the state in which a roughening was prevented by protrusion.

먼저, 도 5와 같이, 흡입구체(20)의 높이를 조절하지 않은 상태로 사용하는 경우, 프론트 휠 캐리지(25)는 흡입구체(20)와 마찬가지로 피청소면에 대하여 대략 수평상태를 유지한다.First, as shown in FIG. 5, when the height of the suction inlet 20 is not adjusted, the front wheel carriage 25 maintains a substantially horizontal state with respect to the surface to be cleaned similarly to the suction inlet 20.

또한, 도 6과 같이, 높이조절장치(23)를 통해 흡입구체(20)의 전방을 소정 높이로 상승시키는 경우, 캠부(23b)에 접촉된 연장부(25f)에 의해 흡입구체(20)의 전방이 상승됨에 따라, 프론트 휠 캐리지(25)는 한쌍의 프론트 휠(25b,25c)이 피청소면에 접촉된 상태로 한쌍의 힌지축(25d,25e)을 중심으로하여 전방이 하향되게 경사진다. 이때, 프론트 휠 캐리지(25)의 몸체 후방(25g)에 형성된 만곡부(25h)가 처 짐방지돌기(27)의 제1 면(27a)에 대항하는 상태로 접촉되면서, 힌지축(25d,25e)을 기준으로 프론트 휠 캐리지(25)의 몸체 후방(25g)에 장력이 발생된 상태로 프론트 휠 캐리지(25)가 강제 피봇된다.In addition, as shown in FIG. 6, when the front of the suction port 20 is raised to a predetermined height through the height adjusting device 23, the suction port 20 is extended by the extension part 25f that is in contact with the cam part 23b. As the front is raised, the front wheel carriage 25 is inclined forward downward with respect to the pair of hinge shafts 25d and 25e with the pair of front wheels 25b and 25c in contact with the surface to be cleaned. At this time, the curved portion 25h formed in the body rear 25g of the front wheel carriage 25 is in contact with the first surface 27a of the anti-deflection projection 27, the hinge shaft (25d, 25e) The front wheel carriage 25 is forcibly pivoted in a state where tension is generated in the rear body 25g of the front wheel carriage 25 based on the reference.

한편, 도 7과 같이, 흡입구체(20)의 높이조절이 해제된 상태에서, 흡입구체(20)를 들어올렸을 경우, 프론트 휠 캐리지(25)는 한쌍의 힌지축(25d,25e)을 중심으로 전방이 자중에 의해 화살표 F1방향으로 선회하려고 하는데, 이때, 한쌍의 힌지축(25d,25e)의 위치보다 더 후방으로 돌출된 몸체(25a)의 후방(25g)이 화살표 F2방향으로 선회하려고 함에 따라 처짐방지돌기(27)의 제1 면(27a)에 가압 접촉된 상태가 되어, 프론트 휠 캐리지(25)의 전방이 화살표 F1방향으로 선회하는 것을 억제한다.On the other hand, as shown in Figure 7, when the suction inlet 20 is lifted in the height adjustment state of the suction inlet 20, the front wheel carriage 25 is centered around a pair of hinge axes (25d, 25e) The front tries to turn in the direction of arrow F1 by its own weight, at which time the rear 25g of the body 25a protruding further back than the position of the pair of hinge shafts 25d and 25e tries to turn in the direction of arrow F2. It comes into a state of being in pressure contact with the first surface 27a of the deflection preventing protrusion 27, and the front wheel carriage 25 is prevented from turning in the direction of the arrow F1.

이에 따라, 본 발명의 일 실시예에서는 프론트 휠 캐리지(25)가 높이조절장치(23)의 작동에 연동하여 흡입구체(20)의 높이를 설정할 수 있는 것은 물론이고, 흡입구체가 들어올려진 상태로 이동 시, 처짐방지돌기(27)를 통해 프론트 휠 캐리지(25)가 자중에 의해 중력방향으로 처지는 것을 방지할 수 있다.Accordingly, in one embodiment of the present invention, the front wheel carriage 25 can set the height of the suction inlet 20 in conjunction with the operation of the height adjusting device 23, as well as move to the state in which the suction inlet is lifted. At the time, the front wheel carriage 25 can be prevented from sagging in the direction of gravity due to its own weight through the deflection preventing protrusion 27.

상기한 바와 같이 본 발명에 있어서는, 진공처소기를 소정 높이로 들어올린 상태로 다른 곳으로 이동할 때, 프론트 휠 캐리지가 흡입구체의 저면으로부터 중력방향으로 돌출되는 것을 억제하여 이동 중에 프론트 휠 캐리지가 문턱 등과 충돌하여 파손되는 것을 미연에 방지할 수 있는 이점이 있다.As described above, in the present invention, when moving the vacuum cleaner to a predetermined height, the front wheel carriage is prevented from protruding in the direction of gravity from the bottom surface of the inlet port, so that the front wheel carriage is moved at the threshold and the like. There is an advantage that can be prevented in advance to crash and break.

이상에서는 본 발명을 특정의 바람직한 실시예를 예를 들어 도시하고 설명하 였으나, 본 발명은 상기한 실시예에 한정되지 아니하며 본 발명의 정신을 벗어나지 않는 범위 내에서 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 다양한 변경과 수정이 가능할 것이다.While the present invention has been illustrated and described with reference to certain preferred embodiments, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described embodiments. Many changes and modifications will be possible to those skilled in the art.
