Poor situation.

본 발명은 로봇청소기의 하부에 두개의 걸레를 설치함에 있어 강력한 회전력을 발생시켜야하고 두개의 걸레가 서로 반대의 방향으로 회전하여야 하며 회전속도가 동일하도록 구성하는 것을 기술적 과제로 한다.The present invention is to provide a strong rotational force in the installation of the two mop in the lower part of the robot cleaner, the two mop should be rotated in the opposite direction to each other and to configure the rotational speed is the technical problem.

본 발명에서는 상기의 기술적 과제를 해결하기 위하여, 도1에서 볼 수 있는 바와 같이 로봇청소기본체(1)의 하부에 회전 가능한 두개의 원형 회전체(3)가 본체와 일체형으로 형성된 원형의 회전체가이드(4) 내부에서 회전하도록 조립하고 회전체(3)에 극세사걸레(2)를 암수의 구조로 이루어진 상용의 벨크로테잎에 의해 탈착 및 부착이 가능하도록 구성함으로서, 로봇청소기가 걸레청소를 완료한 후 사용자가 극세사걸레(2)를 세척하기 위하여 회전체(3)로부터 극세사걸레(2)를 탈착하고 세척 후에 다시 부착할 수 있도록 되어있다.In the present invention, in order to solve the above technical problem, as shown in Figure 1, the circular rotating body guide is formed in one body and two circular rotating body (3) rotatable in the lower part of the robot cleaning base (1) (4) By assembling to rotate in the inside and by attaching and detaching the microfiber mop (2) to the rotating body (3) by a commercial Velcro tape made of a male and female structure, the robot cleaner after cleaning the mop In order to clean the microfiber mop (2), the user can detach the microfiber mop (2) from the rotating body (3) and attach it again after washing.

본 발명의 회전체(3) 작동원리나 감속원리를 자세히 살펴보면,Looking at the principle of operation of the rotating body (3) or the deceleration of the present invention in detail,

도2에서는 로봇청소기본체(1)의 중앙부에 회전걸레의 동력원인 전동모터(7)를 배치하고 청소기본체 내부에 감속기어뭉치(8)가 조립된 상태에서 기어박스커버(6)가 분리되어 있는 상태를 나타낸 것으로서 기어박스커버(6)는 다수의 커버고정볼트(5)에 의하여 청소기본체에 형성된 조립보스(21)에 견고히 고정되어 감속기어뭉치(8)는 외부로 이탈되지 않고 정 위치에서 감속의 역할을 수행할 수가 있다.In FIG. 2, the electric motor 7 which is the power source of the rotary mop is disposed at the center of the robot cleaning base 1, and the gearbox cover 6 is separated in the state where the gear reducer 8 is assembled inside the cleaning base. As shown, the gearbox cover 6 is firmly fixed to the assembly boss 21 formed on the cleaning base by a plurality of cover fixing bolts 5 so that the gear reducer 8 is decelerated at the correct position without being separated outward. Can play the role of

도3 내지 도4에서 감속기어부에 대한 상세한 조립구조 및 감속의 원리를 살펴보면, 전동모터(7)는 로봇청소기본체(1)의 내부에 모터의 외부 형상에 일치하도록 형성된 모터고정부b(23) 위에 놓여진 상태에서 기어박스커버(6)의 일부분에 역시 모터의 외부 형상과 일치하도록 형성된 모터고정부a(22)에 의해 고정될 수 있는 구조로서 커버고정볼트(5)를 사용하여 기어박스커버(6)를 청소기본체의 조립보스(21)에 조립함으로서 확실히 고정되어 진다.Looking at the detailed assembly structure and the principle of the deceleration of the reduction gear in Figures 3 to 4, the electric motor (7) is a motor fixing part b (23) formed to match the external shape of the motor inside the robot cleaning base (1) The gearbox cover using the cover fixing bolt (5) as a structure that can be fixed to a portion of the gearbox cover (6) in the state laid on it by the motor fixing portion (22) also formed to match the external shape of the motor ( 6) is firmly fixed by assembling the assembly boss 21 of the cleaning base.

또한, 감속기어뭉치(8)는 여러 개의 기어부품이 상호 연관되어 조립되어 이루어졌으며 로봇청소기본체(1)의 중앙부에 형성된 감속기어뭉치가이드(13)에 삽입되어 회전체조립홀(15)을 기준으로 회전운동을 하도록 구성되어지고 전동모터(7)가 회전하게 되면 설계된 감속비에 의해 전동모터(7)에서 발생된 동력을 회전체(3)로 감속하여 전달하게 되며 회전체(3)의 하단 바닥에는 극세사걸레(2)의 윗면에 붙어있는 상용의 벨크로테잎F(14)의 상대인 벨크로테잎M(24)이 붙어있으므로 극세사걸레(2)는 회전체(3)에 탈착 또는 부착할 수 있도록 구성되어 진다.In addition, the reduction gear assembly (8) is made by assembling a number of gear parts are interrelated with each other, and is inserted into the reduction gear assembly guide (13) formed in the center of the robot cleaning base (1) based on the rotating body assembly hole (15) When the electric motor (7) is rotated to rotate the power to the rotary body (3) by reducing the power generated from the electric motor (7) by the designed reduction ratio is transmitted to the bottom bottom of the rotor (3) Since the Velcro tape M (24), which is a counterpart of the commercial Velcro tape F (14) attached to the upper surface of the microfiber mop (2), is attached, the microfiber mop (2) is configured to be detachable or attached to the rotating body (3). It is done.

도4에서는 본 발명의 감속기어뭉치(8)와 회전체(3)의 구성과 조립상태를 상세히 확인할 수 있으며 전체적인 동력 전달 경로를 살펴보면 , 전동모터(7)의 축단에 고정된 웜(12)과 맞물려 있는 웜휠(11)의 윗면에 형성된 다수의 감속기어고정축(18)에 각각의 감속기어(10)가 삽입되어 정 위치에서 회전이 가능하게 되고 다수의 감속기어(10)에 맞물린 상태에서 중앙부에 피니언(9)이 조립되고 피니언(9)의 내부에는 회전체(3)의 윗단부에 형성된 고정돌기(17)의 형상에 대응되는 홈이 가공되어 있어서 회전체(3)가 암수의 구조로 결합되어 진다In Figure 4 can be confirmed in detail the configuration and assembly state of the reduction gear assembly (8) and the rotating body (3) of the present invention and looking at the overall power transmission path, the worm 12 and fixed to the shaft end of the electric motor (7) and Each reduction gear 10 is inserted into the plurality of reduction gear fixing shafts 18 formed on the upper surface of the engaged worm wheel 11 so that rotation is possible at a fixed position and is engaged with the plurality of reduction gears 10 in the center portion. The pinion 9 is assembled and a groove corresponding to the shape of the fixing protrusion 17 formed on the upper end of the rotor 3 is machined inside the pinion 9 so that the rotor 3 is joined in a male and female structure. Become

결국, 회전체(3)의 고정돌기(17)는 로봇청소기본체(1)에 형성된 회전체조립홀(15)을 관통하여 피니언(9)에 조립된 상태에서 피니언고정볼트(16)에 의해 분리되지 않도록 확실히 고정되어 있고, 웜휠(11) 및 감속기어(10)에 의해 동력을 전달하도록 구성되어 있으며, 그 상부에는 기어박스커버(6)가 커버고정볼트(5)에 의해 로봇청소기본체(1)에 고정되어 있기 때문에 전동모터(7)가 회전하게 되면 전동모터(7)의 회전축단에 고정된 웜(12)이 회전하고 웜(12)에 맞물려 있는 웜휠(11)이 회전하게 되며 다수의 감속기어(10)가 피니언(9)을 회전시킴으로서 피니언(9)은 강력한 회전력으로 회전하게 되고 피니언(9)과 맞물려 있는 회전체(3)가 회전하게 됨으로서 극세사걸레(2)가 회전하게 되어 걸레청소의 역할을 수행할 수가 있다.As a result, the fixing protrusion 17 of the rotating body 3 is separated by the pinion fixing bolt 16 in the state of being assembled to the pinion 9 through the rotating body assembly hole 15 formed in the robot cleaning base 1. It is fixed so as not to be fixed, and is configured to transmit power by the worm wheel 11 and the reduction gear 10, and the gear box cover 6 is the upper part of the robot cleaning body (1) by the cover fixing bolt (5). When the electric motor 7 rotates, the worm 12 fixed to the rotary shaft end of the electric motor 7 rotates and the worm wheel 11 engaged with the worm 12 rotates. As the reduction gear 10 rotates the pinion 9, the pinion 9 rotates with a strong rotational force, and the rotating body 3 engaged with the pinion 9 rotates so that the microfiber mop 2 rotates. Can perform the role of cleaning.

본 발명은 두개의 걸레가 동일한 속도로서 서로 반대의 방향으로 회전 가능하도록 하고 다수의 감속기어를 사용하여 큰 감속비를 구성함으로서 로봇청소기가 진행시 휘어지지 않고 직진운동을 할 수 있도록 하며 강력한 회전력으로 효과적인 걸레청소 기능을 수행할 수 있도록 해준다.The present invention allows the two mops to rotate in the opposite direction at the same speed, and by using a plurality of reduction gears to configure a large reduction ratio, so that the robot cleaner does not bend during progression, it can move straight and effective with a strong rotational force Allows you to perform mop cleaning function.
