Description

걸레가 장착된 진공청소기{A vacuum cleaner that can sweep with a floorcloth}A vacuum cleaner that can sweep with a floorcloth}

본 발명은 걸레가 장착된 진공청소기에 관한 것으로서, 종래 진공청소기와 물걸레질을 별도로 사용하여야 했던 불편함을 해결하고자 발명된 걸레가 장착된 진공청소기에 관한 것이다.The present invention relates to a vacuum cleaner equipped with a mop, and relates to a vacuum cleaner equipped with a mop invented to solve the inconvenience of having to separately use a conventional vacuum cleaner and a mop.

청소는 보통 쓸고 닦는다는 말로 예로부터 대변되고 있으며 쓴다는 것은 비교적 큰 쓰레기나 먼지 등을 빗자루를 이용해서 치우는 작업을 말하며 닦는다는 건 걸레등을 이용해서 작은 먼지나 얼룩을 제거하는 걸로 대표할 수 있다.Cleaning is usually represented by sweeping and wiping, and sweeping refers to the removal of relatively large garbage or dust with a broom.

현재 가정에서 빗자루의 역할를 대신하고 있는 건 진공청소기로 청소의 효과와 편리함에서 뛰어난 효과를 가지고 있다.The broom that replaces the role of a broom in the home now has an excellent effect on the effectiveness and convenience of cleaning.

하지만 진공청소기가 아주 미세한 먼지나 얼룩 등을 제거할 수는 없으며 때문에 물걸레질이 필요하게 되어 청소에 대한 부담이 상당히 남아있다.However, vacuum cleaners can't remove very fine dust or stains, which requires mopping, which leaves a considerable burden on cleaning.

따라서 한번에 쓸고 닦는 모든 작업을 할 수 있는 청소기의 개발은 청소 시간을 줄이고 능률을 높이는 길이 될 것이다.Therefore, the development of a cleaner that can do all the sweeping and wiping at once will be a way to reduce cleaning time and increase efficiency.

본 발명은 상기와 같은 문제점을 해결하고자 발명된 것으로서 그 목적은 물걸레 청소를 겸할 수 있는 진공청소기를 제공하는데 있다.The present invention was invented to solve the above problems, and an object thereof is to provide a vacuum cleaner that can serve as a mop cleaning.

또한 마찰에 의한 저항이나 진공흡입기의 흡입력이 증가 또는 감속하더라도안정적인 회전운동을 할 수 있는 구동부를 제공하는데 있다.Another object of the present invention is to provide a driving unit capable of stable rotational movement even if the resistance due to friction or the suction force of the vacuum suction unit increases or decreases.

상기와 같은 목적을 달성하기 위하여 본 발명은 저면에 형성된 공기흡입구와 연결된 밀폐된 연통와, 상기 연통의 타측에 연결된 원통형의 휀장착부와, 상기 휀장착부에 연결되어 타측에 호스장착부가 형성된 진공흡입부와, 저면 양측에 각각 형성된 원형의 삽입홈과, 상기 삽입홈의 중앙에 형성된 축장착홀로 이루어진 케이스와;In order to achieve the above object, the present invention provides a sealed communication connected to an air inlet formed on a bottom surface, a cylindrical shock mount part connected to the other side of the communication, and a vacuum suction part connected to the shock mount part and having a hose mounting part on the other side. A case consisting of circular insertion grooves formed on both sides of the bottom, and shaft mounting holes formed at the center of the insertion grooves;

상기 휀장착부 내부에 장착되어 공기흡입부로 인입되는 공기와 충돌하여 회전하는 휀과, 상기 케이스 내부에서 수평방향의 양측 부쉬로 고정되고 휀장착부를 관통하여 휀과 연결된 회전축과, 상기 휀장착부의 좌우측 회전축에 웜기어가 양측에 각각 형성됨으로 이루어지는 구동부와;휀 which is mounted inside the shock mount and rotates by colliding with air introduced into the air intake, a rotating shaft fixed to both side bushes in the horizontal direction inside the case and connected to the shock through the shock mount, and the left and right rotation shafts of the shock mount. A driving unit comprising a worm gear formed at both sides thereof;

상기 양측 웜기어에 각각 상응하여 연동하는 웜휠과, 상기 케이스의 저면에 형성된 삽입홈에 상응하는 원판형의 걸레부착판과, 상기 웜휠과 걸레부착판를 축장착홀을 통하여 연결하는 축으로 이루어진 회전판으로 구성됨을 특징으로 하는 걸래가 장착된 진공청소기에 관한 것이다.It consists of a worm wheel interlocked corresponding to each of the worm gears on each side, a disk-shaped mop attached plate corresponding to the insertion groove formed in the bottom surface of the case, and a rotating plate made of a shaft connecting the worm wheel and the mop attached plate through the shaft mounting hole.

이에 본 발명의 구성을 첨부된 도면에 의하여 당업자가 용이하게 이해하고 재현할 수 있도록 상세히 설명하면 다음과 같다.Accordingly, the configuration of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.

도 1은 본 발명의 일 실시 예를 나타낸 분해사시도이며 도 2는 본 발명의 일실시 예에 따른 부분 절개도로서, 저면에 형성된 공기흡입구(11)와 연결된 밀폐된 연통(12)와, 상기 연통(12)의 타측에 연결된 원통형의 휀장착부(13)와, 상기 휀장착부(13)에 연결되어 타측에 호스장착부(14a)가 형성된 진공흡입부(14)와, 저면 양측에 각각 형성된 원형의 삽입홈(15)과, 상기 삽입홈(15)의 중앙에 형성된 축장착홀(16)로 이루어진 케이스(1)와;1 is an exploded perspective view showing an embodiment of the present invention, Figure 2 is a partial cutaway view according to an embodiment of the present invention, the closed communication 12 connected to the air inlet 11 formed on the bottom and the communication Cylindrical shock mount portion 13 connected to the other side of (12), vacuum suction portion 14 connected to the shock mount portion 13 and having a hose mount portion 14a formed on the other side, and circular insertions respectively formed on both sides of the bottom surface. A case (1) consisting of a groove (15) and an axial mounting hole (16) formed in the center of the insertion groove (15);

상기 휀장착부(13) 내부에 장착되어 공기흡입부(11)로 인입되는 공기와 충돌하여 회전하는 휀(21)과, 상기 케이스(1) 내부에서 수평방향의 양측 부쉬(22)로 고정되고 휀장착부(13)를 관통하여 휀(21)과 연결된 회전축(23)과, 상기 휀장착부(13)의 좌우측 회전축(23)에 웜기어(24)가 양측에 각각 형성됨으로 이루어지는 구동부(2)와;The shock absorber 21 is mounted inside the shock absorbing part 13 and rotates by colliding with air introduced into the air suction part 11, and is fixed to both side bushes 22 in the horizontal direction in the case 1. A driving part 2 formed through the mounting part 13 and a rotation shaft 23 connected to the shock 21 and worm gears 24 formed on both sides of the left and right rotation shaft 23 of the shock mounting part 13;

상기 양측 웜기어(24)에 각각 상응하여 연동하는 웜휠(31)과, 상기 케이스(1)의 저면에 형성된 삽입홈(15)에 상응하는 원판형의 걸레부착판(32)과, 상기 웜휠(31)과 걸레부착판(32)를 축장착홀(16)을 통하여 연결하는 축(33)으로 이루어진 회전판(3)으로 구성됨을 특징으로 하는 걸래가 장착된 진공청소기를 나타내었다.Worm wheels 31 interlocked corresponding to the worm gears 24 on both sides, disc-shaped mop attachment plates 32 corresponding to the insertion grooves 15 formed on the bottom surface of the case 1, and the worm wheels 31. ) And a mop mounted vacuum cleaner, characterized in that it consists of a rotating plate (3) consisting of a shaft (33) connecting the mop attachment plate (32) through the shaft mounting hole (16).

즉 공기흡입구(11)를 통하여 인입되는 공기는 연통(12)을 지나 휀(21)을 구동시키게 되며 이 회전력은 양측에 형성된 웜기어(24)와 웜휠(31)을 통하여 회전판(3)을 회전시키게 된다.That is, the air introduced through the air inlet 11 drives the fan 21 through the communication 12, and the rotational force rotates the rotary plate 3 through the worm gear 24 and the worm wheel 31 formed on both sides. do.

이때 상기 웜기어(24)와 웜휠(31)은 방향을 전환하는 역할 뿐만 아니라 회전축(23)의 빠른 회전의 속도를 적당한 속도로 늦추는 역할을 하게 된다.At this time, the worm gear 24 and the worm wheel 31 serves to change the direction as well as to slow down the speed of the rapid rotation of the rotary shaft 23 to an appropriate speed.

또한 상기 회전축(23)에는 하나 이상의 플라이휠(25)을 장착하도록 하여 회전판(3)이 장애물이나 바닥과의 강한 압력으로 회전력이 감소하게 되거나 또 공기흡입구(11)가 이물질에 의해 흡입력이 순간적으로 저하될 경우에도 관성력에 의하여 지속적인 회전운동을 할 수 있도록 하는 것이 바람직한 실시 예일 것이다.In addition, the rotary shaft 23 is equipped with one or more flywheels 25 so that the rotational force is reduced by the strong pressure of the rotary plate 3 with the obstacle or the floor, or the suction force is momentarily lowered by the foreign matter in the air inlet 11 Even if it would be a preferred embodiment to enable the continuous rotational motion by the inertial force.

도 3은 본 발명의 일 실시 예에 따른 배면도로서, 상기 케이스(1)의 저면에는 하나 이상의 바퀴(17)를 장착하도록 하여 작업을 할때 용이하게 지면을 굴러가도록 하며 상기 바퀴(17)는 바닦과 케이스(1)의 저면과의 거리를 적당히 조절하도록 하여 공기흡입과 회전판(3)을 이용한 걸래질에 최적의 상태를 유지할 수 있도록 하는 것이 바람직하다.Figure 3 is a rear view according to an embodiment of the present invention, the bottom surface of the case 1 to be equipped with one or more wheels 17 to easily roll the ground when working and the wheels 17 It is preferable that the distance between the bottom and the bottom of the case 1 is appropriately adjusted to maintain the optimum state for the air suction and the lapping using the rotating plate 3.

또한 상기 걸레부착판(32)의 저면에는 하나 이상의 걸래 장착홀(34)을 형성하여 상기 걸레부착판(32)과 장착홀(34)에 상응하는 걸레를 장착할 수 있도록 하였다.In addition, the bottom surface of the mop attachment plate 32 is formed by one or more mop mounting holes 34 to mount the mop corresponding to the mop attachment plate 32 and the mounting hole 34.

상술한 바와 같이 본 발명은 물걸레질과 진공청소를 같이 할 수 있도록 하여 청소시간을 절약하고 능률을 높일 수 있는 효과가 있다.As described above, the present invention has the effect of saving the cleaning time and increasing the efficiency by allowing both mopping and vacuum cleaning.

또한 물걸레 부분이 청소하고자하는 부분과 밀착이 되어 회전력이 감소하거나 공기흡입이 용이하지 않아 팬의 회전력이 감소할지라도 플라이휠에 의한 관성으로 지속적이고 안정적인 회전력으로 안정적으로 청소할 수 있는 효과가 있다.In addition, even if the mop part is in close contact with the part to be cleaned, the rotational force is reduced or the air intake is not easy, so even if the rotational force of the fan is reduced, there is an effect that it can be stably cleaned with the continuous and stable rotational force by the inertia by the flywheel.
