본 고안은 절전형 진공청소기의 모터소음 및 전력소모를 줄일수 있는 압력스위치에 관한 것으로, 특히 단자를 서로 이어주는 스프링의 좌,우 유동을 방지함으로서 전기적 단락을 방지하고, 작동 신뢰성을 향상시킬수 있는 진공청소기의 압력스위치 접점 고정장치에 관한 것이다.The present invention relates to a pressure switch that can reduce motor noise and power consumption of a power saving vacuum cleaner, and in particular, prevents an electrical short circuit by preventing left and right flow of springs connecting terminals to each other, and improves the operation reliability. It relates to a pressure switch contact fixing device.

일반적으로 진공청소기를 사용하는 경우에 있어서는 브러쉬 구조가 바닥에 접촉하고 있는 상태와 브러쉬 구조가 바닥으로부터 이격되어 있는 상태로 구분될 수 있다. 물론 브러쉬 구조가 바닥에 접촉하고 있는 상태에서는 전동 모터의 회전에 의하여 발생된 흡인력에 의하여 바닥에 있는 먼지등의 오염물들이 브러쉬 구조의 흡입구를 경유하여 흡입되므로 청소가 이루어지나, 브러쉬 구조가 바닥으로부터 이격되어 있는 상태에서는 전동모터는 단순히 공회전을 하게되어 불필요한 전력소모의 원인이 될 뿐 아니라 전동모터가 지속적으로 공회전하기 때문에 소음이 더욱 크게 발생한다.In general, in the case of using a vacuum cleaner may be divided into a state in which the brush structure is in contact with the floor and a state in which the brush structure is spaced apart from the floor. Of course, in the state where the brush structure is in contact with the floor, cleaning is performed because contaminants such as dust on the floor are sucked through the inlet of the brush structure by the suction force generated by the rotation of the electric motor, but the brush structure is separated from the floor. In this state, the electric motor simply idles, causing unnecessary power consumption, and the noise is generated even more because the electric motor continuously idles.

따라서 본 발명자는 압력스위치를 사용하여 집진실내의 압력의 변화에 따라 전동모터에 공급되는 전력량을 조절하여 브러쉬 구조가 바닥에 접촉하고 있는 상태에서는 사용자가 조작스위치로 설정한 대로의 전력량을 전동모터에 공급하여 원하는 흡인력을 내도록 하고, 브러쉬 구조가 바닥으로부터 이격되어 있는 상태에서는 전동모터에 공급되는 전력량이 최소가 되도록 하여 불필요한 전력소모를 방지할 뿐 아니라 전동모터의 공회전에 따른 소음의 발생을 최소화한 절전형 진공청소기를 제1도에 도시한 바와같이 제안하였다. 또한, 종래의 압력스위치(10)는 하우징(11), 상기 하우징(11)의 내측벽에 밀착되어 상기 하우징(11)의 내부를 밀봉하는 패킹(12), 상기 패킹(12)의 하단부에 인접하여 위치하는 이동단자받침(13), 상기 이동단자받침(13)의 하단부에 고정된 이동단자(14), 상기 이동단자(14)와 전기적으로 연결되어 상기 이동단자(14)를 지지하고 있는 스프링(15). 상기 스프링(15)에 전기적으로 연결되어 있는 제1고정단자(16), 상기 하우징(11)과 결합하며, 상기 스프링(15)과 상기 제1고정단자(16)를 지지하는 프레임(17), 상기 프레임(17)에 고정되며, 상기 스프링(15)과 접촉하지 아니하며 상기 스프링(15)의 중앙을 통과하여 상기 프레임(17)으로부터 상기 이동단자(14)에 인접한 위치까지 수직으로 연장되어 있는 제2고정단자(18) 및 상기 패킹(12)으로 밀폐된 내부공간을 집진실(21)과 유체적으로 연결하는 연결관(19)으로 이루어지고, 제1고정단자(16)와 제2고정단자(18)가 전원과 전동모터(22)사이에 전기적으로 연결되어 있으며, 저항(23)에 병렬로 연결된 구조를 갖는다. 따라서, 상기와 같은 진공청소기는 브러쉬 구조가 바닥에 밀착되면 상기 압력스위치(10)가 연결되어 전동모터(22)에 충분한 전력을 공급하므로써 충분한 청소력을 발휘하도록 하고, 브러쉬 구조가 바닥으로부터 이격되면 상기 압력스위치(10)가 단락되어 전동모터(22)에는 최소한의 전력만을 공급하도록 하여 불필요한 전력의 낭비를 억제함과 동시에 전동모터(22)의 공회전을 최소화하므로써 소음발생을 최대한 억제할 수 있다. 그러나, 종래의 압력스위치(10)는 양단자(16)(18)를 전기적으로 연결하는 스프링(15)이 좌,우로 유동되어 정확하게 양단자(16)(18)를 전기적으로 연결하지 못하는 문제점을 갖는 것이다. 이는 스프링(15)이 아무런 고정수단 없이 이동단자(14)와 프레임(17)사이에 배치된 것이기 때문에 이동단자(14)의 상,하 이동중에 스프링(15)이 좌측 또는 우측으로 이동됨으로서 스프링(15)의 하단부가 제1고정단자(16)와 정확하게 일치하지 못하는 문제점을 갖는 것이다.Therefore, the present inventor adjusts the amount of electric power supplied to the electric motor according to the pressure change in the dust collecting chamber using the pressure switch, so that the amount of electric power as set by the user's operation switch is set to the electric motor when the brush structure is in contact with the floor. Power supply to provide the desired suction force, and the brush structure is spaced from the floor to minimize the amount of power supplied to the electric motor to prevent unnecessary power consumption and to minimize the generation of noise due to idle idling of the motor A vacuum cleaner was proposed as shown in FIG. In addition, the conventional pressure switch 10 is in close contact with the housing 11, the packing 12 to be in close contact with the inner wall of the housing 11 to seal the inside of the housing 11, the lower end of the packing 12 The mobile terminal support 13 is positioned to be positioned, the mobile terminal 14 fixed to the lower end of the mobile terminal support 13, the spring electrically connected to the mobile terminal 14 to support the mobile terminal 14 (15). A first fixed terminal 16 electrically connected to the spring 15, a frame 17 coupled to the housing 11 and supporting the spring 15 and the first fixed terminal 16; It is fixed to the frame 17, and is not in contact with the spring 15 and extends vertically from the frame 17 to a position adjacent to the mobile terminal 14 through the center of the spring (15) 2 fixed terminal 18 and the connecting tube 19 for fluidly connecting the inner space sealed by the packing 12 and the dust collecting chamber 21, the first fixed terminal 16 and the second fixed terminal 18 is electrically connected between the power source and the electric motor 22, and has a structure connected in parallel to the resistor (23). Therefore, the vacuum cleaner as described above, when the brush structure is in close contact with the floor, the pressure switch 10 is connected to provide a sufficient cleaning power by supplying sufficient power to the electric motor 22, and when the brush structure is spaced apart from the floor Since the pressure switch 10 is short-circuited, the electric motor 22 may be supplied with only a minimum amount of power, thereby minimizing waste of unnecessary power and minimizing idle rotation of the electric motor 22, thereby minimizing noise generation. However, the conventional pressure switch 10 has a problem that the spring 15 for electrically connecting both terminals 16 and 18 is flowed to the left and right, so that the terminals 16 and 18 cannot be electrically connected correctly. To have. This is because the spring 15 is disposed between the mobile terminal 14 and the frame 17 without any fixing means, so that the spring 15 is moved to the left or right during the up and down movement of the mobile terminal 14. The lower end of 15) has a problem that does not exactly coincide with the first fixed terminal 16.

본 고안은 상기와 같은 종래의 문제점을 해소하기 위하여 안출된 것으로서, 이동단자의 상,하이동중에 스프링의 좌,우유동이 방지됨으로서 양단자 사이의 전기적 연결을 확실하게 보장하여 작동신뢰성을 크게 향상시킨 진공청소기의 압력스위치 접점 고정장치를 제공함에 그 목적이 있다.The present invention has been devised to solve the above-mentioned problems, and the left and right flow of the spring is prevented during the up and down movement of the mobile terminal, thereby ensuring the electrical connection between both terminals, thereby greatly improving the operation reliability. It is an object to provide a pressure switch contact fixing device of a vacuum cleaner.
