[고안의 분야][Field of design]
본 고안의 진공청소기의 동력솔에 관한 것이다. 더욱 구체적으로는 동력솔의 고속회전으로 인한 바닥의 마모방지 및 소음 및 진동을 감소시키기 위한 방진부재가 부착된 진공청소기의 회전솔에 관한 것이다.It relates to a power brush of the vacuum cleaner of the present invention. More specifically, the present invention relates to a rotary brush of a vacuum cleaner equipped with a dustproof member for preventing abrasion of the floor due to the high speed rotation of the power brush and reducing noise and vibration.
[고안의 배경][Design background]
가정 또는 사무실 등에서 점차 사용이 증가되는 진공청소기는 종래 빗자루와 같이 바닥의 먼지를 쓸어모으는 역할을 하는 회전솔을 가지고 있다.Vacuum cleaners, which are increasingly used in homes or offices, have a rotary brush that serves to sweep dust from the floor like a conventional broom.
이러한 솔 중에는 솔틀에 모터를 설치하고, 모터와 회전솔을 벨트풀리 등으로 연결하여 구동시키는 동력솔이 많이 사용되고 있다. 이러한 동력솔은 통상의 무동력솔이 청소하기 힘든 카펫트와 같은 것을 용이하게 청소할 수 있는 잇점이 있었다.Among these brushes, a power brush for installing a motor on the sole and connecting the motor and the rotating brush with a belt pulley and driving the motor is used. This power brush had the advantage of being able to easily clean things such as carpets that are difficult to clean with conventional non-powered brushes.
제1도는 이러한 동력솔의 분해사시도로서, 그 구조는 표면에 2줄의 솔(17)이 부착된 원통형의 회전솔(13)의 일단부는 모터와 연결된 벨트풀리(11)에 연결되고, 회전솔(13)의 양단부에는 고정축(15)이 설치되고, 고정축(15)은 베어링고정자(16)의 내부에 장착된 베어링(16′)에 지지되며, 베어링고정자(16)는 틀(10)의 바닥(12)에 고정되는 구조를 가지고 있다.1 is an exploded perspective view of such a power brush, the structure of which is connected to the belt pulley 11 connected to the motor, one end of the cylindrical rotary brush 13 attached to the surface of the two rows of brushes 17, the rotary brush A fixed shaft 15 is installed at both ends of the 13, and the fixed shaft 15 is supported by a bearing 16 ′ mounted inside the bearing stator 16, and the bearing stator 16 is connected to the frame 10. It has a structure that is fixed to the bottom 12.
그러나 이러한 동력솔은 모터 자체에서 발생되는 소음 뿐 아니라 회전솔(13)의 고정축(15)과 이것을 지지하는 베어링의 동심도의 불량 및 불균형(unblance)에 의한 진동이 바닥(12)에 전달되어 소음발생의 요인이 되었다.However, such a power brush is not only a noise generated by the motor itself, but also a vibration due to a poor and unbalanced concentricity of the fixed shaft 15 of the rotating brush 13 and the bearing supporting the noise to the floor 12, thereby making noise. It was a factor of occurrence.
또한 진동에 의하여 베어링고정자(16) 및 바닥(12)이 손상되는 문제점이 있었다. 즉, 제2도에 도시된 바와 같이 회전솔(13)의 고정축(15)이 연결되는 베어링(16′)을 지지하는 베어링고정자(16)와 바닥(12)이 직접 접촉되어 있으므로 고정축(15)이 베어링의 중심에 잘 맞지 않을 때에는 소음이 발생하거나 무리한 힘이 가해지므로 바닥(12)이 용이하게 마모되거나 손상되는 문제점이 있었다.In addition, there was a problem that the bearing stator 16 and the bottom 12 are damaged by the vibration. That is, as shown in FIG. 2, the bearing stator 16 supporting the bearing 16 'to which the fixed shaft 15 of the rotary brush 13 is connected and the bottom 12 are in direct contact with each other. 15) When the center of the bearing does not fit well, noise or excessive force is applied, so that the bottom 12 is easily worn or damaged.
[고안의 목적][Purpose of designation]
본 고안의 목적은 베어링고정자의 진동이 바닥에 전달되는 것을 방지하여 소음이 감소된 진공청소기의 동력솔을 제공하는데 있다.An object of the present invention is to provide a power brush for the vacuum cleaner to reduce the noise by preventing the vibration of the bearing stator is transmitted to the floor.
본 고안의 다른 목적은 베어링고정자에 의하여 바닥이 손상되는 것을 방지하기 위한 방진부재를 가진 진공청소기의 동력솔을 제공하는데 있다.Another object of the present invention is to provide a power brush of a vacuum cleaner having a dustproof member for preventing the floor from being damaged by the bearing stator.
[고안의 요약]Summary of the proposal
본 고안의 동력솔은 모터에 의하여 구동되는 회전솔의 양단부에 설치된 한쌍의 고정축을 지지하는 베어링을 포함하는 베어링고정자의 외부를 감싸도록 방진부재가 설치되어 있으며, 방진부재는 틀에 고정되는 구조를 가진다.The power brush of the present invention is provided with a dustproof member to surround the outside of the bearing stator including a bearing for supporting a pair of fixed shafts installed on both ends of the rotary brush driven by the motor, the dustproof member is fixed to the frame Have
[고안의 구체예에 대한 설명][Description of Specific Example of Design]
상기한 본 고안의 동력솔(10)을 첨부한 도면을 참고하여 설명하면 다음과 같다.Referring to the accompanying drawings, the power brush 10 of the present invention is as follows.
제3도에 도시된 바와 같이 본 고안에 의한 동력솔은 종래의 것에 베어링 고정자(16)에서 발생되는 충격을 흡수하기 위한 방진부재(18)를 더 포함하는 것을 특징으로 한다.As shown in Figure 3, the power brush according to the present invention is characterized in that it further comprises a dustproof member 18 for absorbing the shock generated by the bearing stator 16 to the conventional one.
즉, 모터에 연결된 벨트풀리(11)를 통한 회전솔(13)의 회전시에 회전축(15)과 베어링(16′)사이의 동심도 불량이나 불균형에 의한 진동을 베어링고정자(16)와 바닥(12)의 사이에 충격흡수를 위하여 방진부재(18)를 삽입함으로서, 진동으로 인한 소음발생 및 바닥(12)의 손상을 방지하는 것이다.That is, when the rotation brush 13 is rotated through the belt pulley 11 connected to the motor, vibrations due to poor concentricity or unbalance between the rotation shaft 15 and the bearing 16 'are prevented from the bearing stator 16 and the bottom 12. By inserting the anti-vibration member 18 for shock absorption between the), it is to prevent the generation of noise and damage to the floor 12 due to vibration.
방진부재(18)는 진동감쇄고무를 사용하며, 이것은 베어링고정자(16)의 표면에 모울딩하여 일체로 제조할 수 있다.The vibration damping member 18 uses vibration damping rubber, which can be manufactured integrally by molding the surface of the bearing stator 16.
본 고안은 기재된 실시예에 대해서만 상세히 설명되었지만 본 고안의 사상과 범위내에서 여러가지로 변형 또는 수정할 수 있음은 이 분야의 당업자에게는 명백한 것이며 따라서 그러한 변형 및 수정은 첨부된 실용신안 등록청구범위에 속하는 것은 당연하다.Although the present invention has been described in detail only with respect to the embodiments described, it will be apparent to those skilled in the art that various modifications or changes can be made within the spirit and scope of the present invention, and such variations and modifications are within the scope of the appended claims. Do.
