Description

진공청소기의 흡입력 조절스위치{Suction regulator of a vacuum cleaner}Suction regulator of a vacuum cleaner {Suction regulator of a vacuum cleaner}

본 발명은 진공청소기에 관한 것이며, 보다 상세하게는 진공모터의 전원 온/오프 제어 및 흡입력 조절을 위한 스위치의 구조를 개선한 진공청소기의 흡입력 조절스위치에 관한 것이다.The present invention relates to a vacuum cleaner, and more particularly, to a suction force control switch of a vacuum cleaner having an improved structure of a switch for controlling power on / off and adjusting suction power of a vacuum motor.

일반적으로 진공청소기는 도 1에 도시된 바와 같이, 본체(B)에 내장된 모터(도시하지 않음)의 구동으로 본체(B)내의 집진실(集塵室)에 강력한 흡입력을 발생시켜 본체(B)의 집진실과 호스(hose:H) 및 연장관(extension wands:P)에 의해 연결된 브러시(brush:R)를 통해서 바닥면의 먼지나 이물질을 흡입한 뒤, 집진실에 장착된 먼지봉투에 포집함으로써 청소작업을 자동으로 수행하는 장치이다.In general, as shown in FIG. 1, the vacuum cleaner generates a strong suction force in the dust collecting chamber in the main body B by driving a motor (not shown) built in the main body B, thereby causing the main body B to be discharged. Dust or foreign substances on the floor through the brush (R) connected by the dust collection chamber and hose (Hse: H) and extension wands (P), and then collected in the dust bag mounted in the dust collection chamber. This is a device that automatically performs the cleaning work.

이와 같이 진공청소기는 모터의 구동에 의해 흡입력을 발생시키는 바, 본체(B)에는 도 2에 도시한 바와 같이, 모터의 구동을 단속하기 위한 전원 스위치(1)가 구비된다. 이러한 전원스위치(1)는 통상 인쇄회로기판(PCB:4)에 설치되는 푸시스위치(2)로 구성되고, 본체(B)에 외측방향으로 탄성바이어스 되게 장착된 푸시버튼(push button:3)에 의해 온(ON)/오프(OFF) 된다.As described above, the vacuum cleaner generates suction force by driving the motor, and as shown in FIG. 2, the main body B is provided with a power switch 1 for controlling the driving of the motor. The power switch 1 is usually composed of a push switch 2 installed on a printed circuit board (PCB) 4, and is provided on a push button 3 mounted elastically biased outwardly to the body B. It turns ON / OFF.

한편, 이러한 진공청소기는 전원스위치(1)의 제어에 의한 모터의 작동으로 흡입력을 발생하지만, 이 흡입력이 과대할 경우에는 브러시(R)가 바닥면에 흡착되어 이동이 어렵게 되는 등 효율적인 청소작업을 저해하게 된다. 또한 청소대상에 따라 작은 흡입력이 요구될 경우도 있고 큰 흡입력이 요구될 경우도 있는데, 예컨대 그다지 큰 흡입력이 요구되지 않는 경우에도 모터가 큰 흡입력으로 일관되게 구동된다면 불필요하게 전력이 낭비될 뿐만 아니라 모터의 수명도 그만큼 단축되게 된다. 따라서 진공청소기에는 필요에 따라 모터의 흡입력을 적절히 조절할 수 있도록 흡입력 조절스위치(5)도 함께 구비되는 것이 일반적이다.On the other hand, such a vacuum cleaner generates suction force by the operation of the motor under the control of the power switch 1, but when the suction force is excessive, the brush R is sucked to the bottom surface, making it difficult to move. Will be inhibited. In addition, depending on the object of cleaning, a small suction force may be required and a large suction force may be required. For example, even if a large suction force is not required, if the motor is driven consistently with a large suction force, power is unnecessary and the motor is not necessary. Is also shortened. Therefore, it is common that the vacuum cleaner is also provided with a suction force control switch 5 to properly adjust the suction force of the motor as necessary.

이러한 흡입력 조절스위치(5)는 PCB(4)에 설치되는 로터리스위치(rotary switch:6)로 구성되며, 이 로터리스위치(6)는 본체(B)에 장착된 조정노브(7)에 의해 조작된다.This suction force control switch 5 is composed of a rotary switch (6) installed on the PCB (4), the rotary switch (6) is operated by the adjustment knob (7) mounted on the main body (B) .

그런데, 이러한 종래의 진공청소기는 전원스위치(1)와 흡입력 조절스위치(5)가 별개의 부품으로 본체(B)에 각각 장착되는 바, 이들을 조작하기 위한 푸시버튼(3) 및 조정노브(7)를 별도로 구비해야 되므로 부품수 증가에 따른 제조원가 상승을 부추길 뿐만 아니라 많은 설치공간을 확보해야 하는 문제가 있었다. 또한 전원스위치(1)와 흡입력 조절스위치(5)가 분리 설치됨으로 인해 사용에 적잖은 불편이 수반되는 문제도 있었다.By the way, such a conventional vacuum cleaner bar power switch (1) and suction force control switch (5) is mounted to the body (B) as a separate component, respectively, the push button (3) and the adjusting knob (7) for operating them Since it must be provided separately, not only to increase the manufacturing cost due to the increase in the number of parts, but also had to secure a lot of installation space. In addition, since the power switch 1 and the suction power control switch 5 is installed separately there was also a problem that is accompanied by a slight inconvenience in use.

본 발명은 상술한 종래의 문제점들을 감안하여 안출된 것으로, 모터를 단속하는 전원스위치와 모터의 흡입력을 제어하는 흡입력 조절스위치를 일체적으로 구성하여 각 스위치를 하나의 노브만으로 조작할 수 있는 진공청소기의 흡입력 조절스위치를 제공함에 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and a vacuum cleaner capable of operating each switch with only one knob by integrally configuring a power switch for controlling the motor and a suction power control switch for controlling the suction power of the motor. Its purpose is to provide a suction force control switch.

이러한 본 발명의 한 바람직한 특징에 의하면, 노브의 보스 외주에 누름판의 상면에 접촉하는 복수의 리브(rib)가 형성된다.According to one preferred feature of this invention, a plurality of ribs are formed on the boss outer periphery of the knob in contact with the upper surface of the pressing plate.

이에 따라 본 발명은, 흡입력 조절스위치의 노브 하나만으로 모터의 온/오프 조작과 모터의 흡입력 조절 조작을 모두 수행할 수 있어 종래의 전원스위치 조작용 푸시버튼 및 그 설치공간을 삭제할 수 있게 되므로 진공청소기의 제조원가 절감과 사용의 편의성 향상에 효과를 발휘하게 된다.Accordingly, the present invention can perform both the on / off operation of the motor and the suction power control operation of the motor with only one knob of the suction power control switch, so that the conventional push button for operating the power switch and its installation space can be deleted. It is effective in reducing the manufacturing cost and improving the convenience of use.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3 및 도 4에서, 본 발명에 의한 진공청소기의 흡입력 조절스위치는, 모터(도시하지 않음)가 내장된 청소기 본체(B)에 회전 및 축방향 이동 가능하게 장착되는 노브(11)와, 이 노브(11)의 조작에 의해서 모터의 흡입력을 조절하도록 PCB(20)에 설치되는 로터리스위치(21)와, 상기 노브(11)에 장착되어 그 이동에 따라 PCB(20)에 설치된 전원스위치(22)를 온/오프 시키는 누름판(16)으로 구성된다.3 and 4, the suction force control switch of the vacuum cleaner according to the present invention, the knob 11 is mounted to the vacuum cleaner body (B) with a motor (not shown) to be rotatable and axially movable, and Rotary switch 21 installed on the PCB 20 to adjust the suction force of the motor by the operation of the knob 11, and a power switch 22 mounted on the knob 11 and installed on the PCB 20 according to the movement of the knob 11 ) Is composed of a pressing plate 16 for turning on / off.

상기 노브(11)는 스커트(skirt:12a)를 갖는 캡형 몸체(12)의 내측 중앙에 고정구멍(13a)을 축방향으로 갖는 보스(13)가 돌출 형성된다. 보스(13)의 선단에는 복수의 훅(14)이 원주방향을 따라 등간격으로 형성되고, 보스(13)의 외주에는 누름판(16)의 상면에 접촉하는 복수의 리브(15)가 역시 원주방향을 따라 등간격으로 형성된다.The knob 11 has a boss 13 protrudingly formed in the inner center of the cap-shaped body 12 having a skirt 12a in the axial direction. At the tip of the boss 13, a plurality of hooks 14 are formed at equal intervals along the circumferential direction, and on the outer circumference of the boss 13, a plurality of ribs 15 contacting the upper surface of the pressing plate 16 are also in the circumferential direction. It is formed along the same interval.

누름판(16)은 노브(11)의 훅(14)들이 각각 탄성적으로 끼워져 걸리는 복수의 결합슬롯(17)을 중앙에 갖는 원반형으로 형성된다. 이에 따라 누름판(16)은 그 결합구멍(17)의 상·하면 가장자리가 복수의 훅(14)과 리브(15) 사이에 개재됨으로써 노브(11)에 위치 고정된다.The pressing plate 16 is formed in a disk shape having a plurality of coupling slots 17 at the centers of which hooks 14 of the knob 11 are elastically fitted. Accordingly, the pressing plate 16 is fixed to the knob 11 by interposing the upper and lower edges of the engaging hole 17 between the plurality of hooks 14 and the ribs 15.

로터리스위치(21)는 노브(11)의 보스(13) 직하방에 위치되고, 전원스위치(22)는 누름판(16)의 주변부 하방에 위치된다.The rotary switch 21 is located directly below the boss 13 of the knob 11, and the power switch 22 is located below the periphery of the pressing plate 16.

로터리스위치(21)의 회전축(21a)에는 이를 노브(11)에 연결하는 전동축(18)이 결합되는데, 이 전동축(18)은 누름판(16)의 중앙을 관통하여 노브(11)의 보스(13) 고정구멍(13a)에 전동 가능하게 결합된다. 이를 위해 전동축(18)은 예를 들어 도 4에 도시된 바와 같이, 사각형으로 구성될 수도 있고, 또는 별도로 도시하지는 않았으나 원형으로 구성되어 결합부가 D커팅될 수도 있다.The rotary shaft 21a of the rotary switch 21 is coupled to the transmission shaft 18 which connects it to the knob 11, which passes through the center of the pressing plate 16 to the boss of the knob 11. (13) It is rotatably coupled to the fixing hole 13a. To this end, the transmission shaft 18 may be configured as a quadrangle, for example, as shown in FIG. 4, or may be circularly cut so that the coupling portion may be cut D, although not separately illustrated.

한편, 본체(B)에는 노브(11)의 보스(13)가 관통하는 관통구멍(A)이 형성되고, 이 관통구멍(A)의 둘레에는 노브(11)의 이동시 그 스커트(12a)의 이동을 안내하기 위한 환형의 안내홈(G)이 적정깊이로 인입 형성된다. 그리고 노브(11)의 몸체(12) 내면과 본체(B) 사이에는 노브(11)를 외측으로 탄성 바이어스시키는 압축코일 스프링(19)이 설치되며, 이에 따라 노브(11)는 본체(B)의 외부로 적절히 돌출된다.On the other hand, in the main body B, a through hole A through which the boss 13 of the knob 11 penetrates is formed, and the skirt 12a is moved around the through hole A when the knob 11 is moved. Annular guide groove (G) for guiding the formed to the appropriate depth. In addition, a compression coil spring 19 for elastically biasing the knob 11 to the outside is installed between the inner surface of the body 12 of the knob 11 and the main body B. Accordingly, the knob 11 is connected to the main body B. Properly projected to the outside.

이와 같이 구성된 본 발명에 의한 진공청소기의 흡입력 조절스위치의 작동은 다음과 같다.The operation of the suction force control switch of the vacuum cleaner according to the present invention configured as described above is as follows.

먼저, 모터를 온/오프 시키고자 할 경우에는 본체(B)의 외부로 돌출된 노브(11)를 하방으로 누른다. 그러면 노브(11)가 압축코일 스프링(19)를 압축하면서 본체(B)내로 이동되고, 이에 따라 노브(11)의 보스(13) 선단부에 장착된 누름판(16)이 노브(11)와 함께 이동됨으로써 전원스위치(22)를 눌러주게 된다. 이어서 노브(11)에 가한 외력을 제거하면, 압축코일 스프링(19)의 복원탄성에 의해 노브(11)는 초기위치로 복귀된다.First, when the motor is to be turned on / off, the knob 11 protruding to the outside of the main body B is pressed downward. Then, the knob 11 is moved into the main body B while compressing the compression coil spring 19, and thus the pressing plate 16 mounted at the tip of the boss 13 of the knob 11 moves with the knob 11. As a result, the power switch 22 is pressed. Subsequently, when the external force applied to the knob 11 is removed, the knob 11 returns to the initial position by the restoring elasticity of the compression coil spring 19.

다음, 모터의 흡입력을 조절하고자 할 경우에는 본체(B)의 외부로 돌출되어 있는 노브(11)를 정방향 또는 역방향으로 적절히 돌린다. 그러면 노브(11)가 본체(B)에 대해 상대적으로 회전됨으로써 이의 보스(13)에 결합된 전동축(18)이 동시에 회전된다. 이에 따라 전동축(18)에 결합된 로터리스위치(21)의 회전축(21a)이 함께 회전됨으로써 모터의 흡입력을 조절하게 된다. 이 때, 누름판(16)은 노브(11)와 함께 회전되지만, 전원스위치(22)가 누름판(16)의 주변부 하방에 위치하므로 어느 위치에서든 전원스위치(22)를 조작할 수 있다.Next, when adjusting the suction force of the motor, appropriately turn the knob 11 protruding to the outside of the main body B in the forward or reverse direction. The knob 11 is then rotated relative to the body B so that the transmission shaft 18 coupled to its boss 13 is rotated simultaneously. Accordingly, the rotary shaft 21a of the rotary switch 21 coupled to the electric shaft 18 is rotated together to adjust the suction force of the motor. At this time, the pressing plate 16 is rotated together with the knob 11, but since the power switch 22 is located below the periphery of the pressing plate 16, the power switch 22 can be operated at any position.

이상에서 설명한 바와 같이 본 발명에 의하면, 흡입력 조절스위치의 노브 하나만으로 모터의 온/오프 조작과 모터의 흡입력 조절 조작을 모두 수행할 수 있으며, 이에 따라 종래와 같은 별도의 전원스위치 조작용 푸시버튼 및 그 설치공간을 삭제할 수 있게 된다.As described above, according to the present invention, both the on / off operation of the motor and the suction force adjustment operation of the motor can be performed using only one knob of the suction force adjustment switch. The installation space can be deleted.

따라서 본 발명은, 진공청소기의 제조원가 절감과 사용의 편의성을 향상시키는 우수한 효과를 가진다.Therefore, the present invention has an excellent effect of reducing the manufacturing cost of the vacuum cleaner and improving the ease of use.
