본 고안은 물걸레기능을 갖는 진공청소기의 물통구조에 관한 것으로, 특히 흡입되는 오염수(물, 오물등)와 먼지가 유입통로를 통해 흡입되는 것을 방지하여 모터의 부식 및 필터설치를 없앨 수 있는 물걸레기능을 갖는 진공청소기의 물통구조에 관한 것이다.The present invention relates to a bucket structure of a vacuum cleaner having a water mop function, and in particular, to prevent the suction of contaminated water (water, dirt, etc.) and dust through the inlet passage to remove the corrosion and filter installation of the motor It relates to a bucket structure of a vacuum cleaner having a function.

종래의 물걸레기능을 갖는 진공청소기는 제1도에 도시한 바와 같이, 본체(1)의 일측에는 하우징(2)내에 삽입설치된 모터(M)가 위치되어 있고, 그 타측에는 내부중앙에 유입통로(3a)를 형성한 오물저장박스(3)가 삽입설치되어 있으며, 상기한 모터(M)와 오물저장박스(3)에 형성된 유입통로(3a)와의 사이에는 필터부재(4)를 개재하여 흡입된 공기를 정화토록 되어 있고, 또한 상기 오물저장박스(3)의 상부개구부에는 일정한 간격을 두고 외부쪽으로 볼록한 만곡선을 형성하는 2중덮개부재(5)가 형성되어 있으며, 상기한 오물저장박스(3)의 일측에는 상기 2중덮개부재(5)와 연통됨과 동시에 도시하지 않은 흡입구체와 연결관(도시안됨)을 매개로 연결되는 흡입관(6)이 설치되어 있다.As shown in FIG. 1, a vacuum cleaner having a conventional mop function has a motor M inserted into the housing 2 on one side of the main body 1, and an inflow passage in the inner center on the other side thereof. The dirt storage box 3 having the 3a formed therein is inserted and installed between the motor M and the inflow passage 3a formed in the dirt storage box 3 via the filter member 4. In order to purify the air, and the upper opening of the waste storage box (3) is formed a double cover member (5) forming a curved line convex outward at regular intervals, the waste storage box (3) At one side of the) is connected to the double cover member 5 and at the same time the suction pipe (not shown) connected to the inlet port (not shown) and the suction port 6 is installed.

이와 같이 구성된 종래의 진공청소기는, 모터(M)의 구동력에 따라 본체(1) 내부에 강력한 흡입력이 발생되면 먼지 및 오염수등과 함께 흡입공기가 본체(1)의 일측에 설치된 흡입관(6)을 통해 흡입되면서 그 흡입관(6)과 연통된 2중덮개부재(5)의 간극통로를 따라 상기 흡입관(6)의 반대편으로 흡입유도되어 진다.In the conventional vacuum cleaner configured as described above, when a strong suction force is generated inside the main body 1 according to the driving force of the motor M, the suction tube 6 provided with suction air on one side of the main body 1 together with dust and contaminated water, etc. The suction is guided to the opposite side of the suction pipe 6 along the gap passage of the double lid member 5 in communication with the suction pipe 6 while being sucked through.

이때, 흡입유도된 먼지는 흡입공기와 함께 오물저장박스(3)내의 중앙에 일체로 형성된 유입통로(3a)를 따라 유입되어서 필터부재(4)에 의해 필터링된 후 정화된 깨끗한 공기만이 모터(M)를 통해 본체(1)의 외부로 배출되고, 한편 흡입유도된 오염수는 오물저장박스(3)의 내측면을 따라 오물저장박스(3)내에 저장되어 진다.At this time, the suction-induced dust is introduced along the inlet passage (3a) integrally formed in the center of the waste storage box (3) together with the suction air, filtered by the filter member (4), the purified air only motor ( The contaminated water discharged to the outside of the main body 1 through M) is sucked and stored in the waste storage box 3 along the inner surface of the waste storage box 3.

그러나, 이와 같은 종래의 기술에서는, 유입통로(3a)의 선단이 완전히 개방되어 있기 때문에 모터(M)의 흡입구동력에 의해 완전하게 분리되지 않은 오염수(예컨대, 수분 및 미세입자의 오물등)가 먼지 및 흡입공기와 함께 유입통로(3a)로 유입되어 필터부재(4)에 필터링됨에 따라 필터부재(4)에 필터링된 오염수 및 먼지등을 소비자가 직접 제거시켜 주어야 하는 불편함과 번거로움이 자주 발생된다는 문제점이 있었고, 또 필터부재(4)를 장기간 사용시에는 필터부재(4)에 의해 필터링 된 오염수로 부터 발생되는 수분이 모터(M)을 부식시켜 성능을 저하시킨다는 문제점도 있었다.However, in such a conventional technique, since the tip of the inflow passage 3a is completely open, contaminated water (e.g., water and fine particles dirt, etc.) that is not completely separated by the suction driving force of the motor M is generated. As it enters the inflow passage 3a together with the dust and the suction air and is filtered by the filter member 4, inconvenience and hassle that a consumer must remove the contaminated water and dust filtered by the filter member 4 directly. There was a problem that occurs frequently, and when the filter member 4 is used for a long time, there was also a problem that moisture generated from the contaminated water filtered by the filter member 4 corrodes the motor M and degrades performance.

따라서, 본 고안은 상기 문제점을 해결하기 위하여 이루어진 것으로써, 본 고안의 목적은, 모터의 흡입구동력에 의해 회전팬이 회전되도록 유입통로의 상측에 회전팬을 설치하여 먼지 및 오염수가 흡입공기와 함께 유입통로를 통해 모터로 유입되는 것을 방지하고, 아울러 모터의 부식을 방지할뿐만 아니라 필터부재를 사용하지 않아도 되는 물걸레기능을 갖는 진공청소기의 물통구조를 제공하는데 있다.Therefore, the present invention has been made to solve the above problems, the object of the present invention is to install a rotary fan on the upper side of the inlet passage so that the rotary fan is rotated by the suction driving force of the motor together with the dust and contaminated water suction air The present invention provides a bucket structure of a vacuum cleaner that prevents the inflow into the motor through the inflow passage, and also prevents the corrosion of the motor, and has a water mop function that does not require the use of a filter member.

The cover member 15 is covered.

다음에는, 이와 같은 구성된 본 고안의 작용효과를 설명한다.Next, the effect of the present invention configured as described above will be described.

제2도 및 제3도에 도시한 바와 같이, 진공청소기의 가동을 위해 전원을 인가시키면, 이 전원을 인가받아 모터(M)가 가동됨에 따라 본체(11)내에 강력한 흡입력이 발생되어 도시하지 않은 흡입구체를 통해 먼지 및 오염수등을 공기와 함께 본체(11)의 일측에 설치된 흡입관(16)을 통해 흡입하게 되며, 또 상기 흡입관(16)으로 공기와 함께 흡입된 먼지 및 오염수등은 오물저장박스(13)의 물통내측덮개부재(13c)와 오물저장박스(13)의 상측개구부를 덮는 덮개부재(15)와의 일정한 간극을 통해 유도되면서 오물저장박스(13)의 내부로 1차수거되고, 일부의 잔여먼지 및 오염수(수분)는 유입통로(13a)로 유입되게 된다.As shown in FIG. 2 and FIG. 3, when power is applied for the operation of the vacuum cleaner, a strong suction force is generated in the main body 11 as the motor M is operated when this power is applied. Through the suction port, the dust and the contaminated water are sucked together with the air through the suction pipe 16 installed at one side of the main body 11, and the dust and the contaminated water sucked with the air into the suction pipe 16 are the dirt. It is first collected into the inside of the waste storage box 13 while being guided through a constant gap between the inner cover member 13c of the storage box 13 and the cover member 15 covering the upper opening of the waste storage box 13. , Some residual dust and contaminated water (water) is introduced into the inflow passage (13a).

이때, 상기 회전팬(17)은 상기 물통내측덮개부재(13c)에 지지됨과 동시에 상기 유입통로(13a)의 상부측에 대해 일정한 간격을 두고 경사지게 위치되어서 상기 모터(M)의 강력한 흡입력에 의해 회전되도록 되어 있기 때문에 상기와 같이 일부의 잔여먼지 및 오염수등은 상기 흡입력에 의해 회전되는 회전팬(17)의 둘레에 형성된 다수개의 날개부(17f)에 의해 차단되어 상기 유입통로(13a)로 유입되지 못함과 동시에, 그 날개부(17f)에 부딪쳐서 방사상으로 분산되어 오물저장박스(13)에 2차수거되며, 또 순수한 흡입공기는 회전팬(17)의 둘레에 형성된 다수개의 공기흡입구(17e)와 차단판(17d)에 형성된 다수개의 공기유입공(17c)을 통해 유입통로(13a)로 유입됨과 동시에 모터(M)내로 흡입되어 본체(11)의 외부로 배출되는 것이다.At this time, the rotary fan 17 is supported by the water tank inner cover member 13c and at an inclined position with respect to the upper side of the inflow passage 13a and rotated by a strong suction force of the motor M. Since some residual dust and contaminated water, as described above, are blocked by a plurality of blades 17f formed around the rotary fan 17 which is rotated by the suction force and flows into the inflow passage 13a. At the same time, a plurality of air intakes 17e formed around the rotary fan 17 are collected and collected in the waste storage box 13 by being distributed radially by hitting the wing 17f. And it is introduced into the inflow passage (13a) through a plurality of air inlet hole (17c) formed in the blocking plate (17d) and is sucked into the motor (M) is discharged to the outside of the main body (11).

이상에서 설명한 바와 같이 본 고안의 물걸레기능을 갖는 진공청소기의 물통구조는, 순수한 흡입공기만이 유입통로를 통해 모터로 유입되도록 그 유입통로의 상부측에 일정한 간격을 두고 회전팬이 흡입력에 의해 회전되는 구조로 되어 있기 때문에 유입통로를 통해 모터로 흡입될려는 잔여먼지 및 오염수를 회전팬에 의해 차단시켜 모터의 부식을 방지할 수 있을 뿐만 아니라, 그 회전팬이 잔여먼지 및 오염수를 미연에 차단시켜줌에 따라 모터의 흡입공에 설치되는 종래의 필터부재의 필요성을 없앨 수 있고, 이로 인하여는 필터부재의 해체 및 먼지 및 오물제거에 따른 소비자의 불편함과 번거로움등을 해소시킬 수 있는 효과가 있다.As described above, the bucket structure of the vacuum cleaner having the water mop function of the present invention has a rotation fan rotated by suction force at regular intervals on the upper side of the inflow passage so that only pure suction air flows into the motor through the inflow passage. Because the structure is designed to prevent the corrosion of the motor by blocking the remaining dust and contaminated water to be sucked into the motor through the inflow passage by the rotating fan, the rotating fan prevents residual dust and contaminated water. By blocking it, the necessity of the conventional filter member installed in the suction hole of the motor can be eliminated, thereby eliminating the inconvenience and hassle of consumers due to the disassembly of the filter member and the removal of dust and dirt. There is.
