본 발명은 진동감지센서를 이용한 진공청소기의 출력조절장치에 관한 것으로, 특히, 진동감지센서를 진공청소기에 적용하여 흡입면의 상태, 흡입되는 먼지량, 먼지의 종류에 따라 청소에 필요한 적절한 흡입력을 자동으로 조절할 수 있게 된 진동감지센서를 이용한 진공청소기의 출력조절장치에 관한 것이다.The present invention relates to an output control device for a vacuum cleaner using a vibration sensor, in particular, by applying the vibration sensor to the vacuum cleaner automatically applies the appropriate suction force required for cleaning according to the state of the suction surface, the amount of dust to be sucked, the type of dust It relates to a vacuum cleaner output control device using a vibration sensor that can be adjusted to.

종래 기술의 진공청소기 출력조절은 압력센서를 이용하거나 광센서 등을 이용하여 진공청소기의 모터속도를 조절토록 하여 청소하고자 하는 구역에 따라 적합한 흡입력을 내도록 하는 구조로 구성되어 있었다.The vacuum cleaner output control of the prior art was configured to provide a suitable suction force according to the area to be cleaned by adjusting the motor speed of the vacuum cleaner using a pressure sensor or an optical sensor.

그러나, 압력센서를 이용한 출력조절장치는 진공청소기 내부의 압력을 측정함으로, 흡입구가 막히면 진공압이 증가하여 먼지가 다량으로 흡입되는 것으로 인식하게 되고, 내부에 있는 먼지수거통의 먼지량을 측정할 경우, 먼지가 가득차 있는 것으로 오판하여 사용에 따른 오동작이 발생되었으며, 또한 광센서를 이용한 출력조절장치는 수광부와 발광부로 구성되어 그 양단에 흐르는, 유로에 섞인 먼지량의 빛의 산란변화로 감지하는 장치로, 이 역시 흡입구가 막히게 되면 먼지가 없다고 판단하는 등, 여러 문제점이 발생되었다.However, the output control device using the pressure sensor measures the pressure inside the vacuum cleaner, and when the suction port is blocked, the vacuum pressure increases to recognize that a large amount of dust is sucked in. When measuring the amount of dust in the dust container inside, Malfunction caused by misuse due to the dust is full, and the output control device using the optical sensor is composed of the light-receiving unit and the light-emitting unit to detect the scattering change of the light amount of dust mixed in the flow path, This also caused a number of problems, such as determining that there is no dust if the suction port is blocked.

이에 본 발명은 상술한 바와 같은 종래의 제반문제점을 감안하여 안출된 것으로, 압전효과를 이용한 압력감지장치(PIEZO FILM)를 진공청소기의 흡입관 적절한 위치에 매설하여 유입되는 먼지 및 각종 불순물 등에 의한 진동으로, 먼지의 량, 먼지의 종류, 흡입상태 등을 감지토록 하여 보다 편리한 사용이 되도록한 진동감지센서를 이용한 진공청소기의 출력조절장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in view of the above-mentioned problems in the related art, and the vibration of dust and various impurities introduced by installing a pressure sensor (PIEZO FILM) using a piezoelectric effect at an appropriate position of a suction tube of a vacuum cleaner is introduced. It is an object of the present invention to provide an output control device for a vacuum cleaner using a vibration sensor for detecting the amount of dust, the type of dust, the suction state, and the like so as to make the use more convenient.

In addition, among the plurality of signals output from the vibration detecting unit (A), a frequency filter having a function of passing only a frequency signal of a specific range or vice versa and removing the frequency filter is combined in parallel in a plurality of different ranges of the specific range. Section (B) and frequency filter section (B) A / D converter (C) that converts information that can be represented by a continuous analog quantity, such as a signal from one, into a digital quantity that can be represented by a combination of signs, and a signal that is output from the A / D converter (C).

It is configured by sequentially combining the operation state display unit (F) to display to.

이와 같이 구성된 본 발명의 일실시예를 들어 작용 및 효과를 설명하면 다음과 같다.Referring to the action and effect of an embodiment of the present invention configured as described above are as follows.

소정의 작동수단을 거쳐 진공청소기(1)를 작동케 되면 작동에 따른 모터의 동작으로 각종 먼지를 흡입케되고, 도면 제2도에서 보는 바와 같이 진공청소기(1)의 흡입관(2) 내부에 형성한 고정돌기(4)에 의해 먼지등이 함유되어 흡입되는 공기가, 화살표 "P"와 같은 방향으로 와류현상을 일으키며 흡입관(2) 내벽에 매설한 진동감지수단인 피에조필름(3)에 진동을 인가하게 되면, 먼지에 의해 얻어지는 진동주파수와 흡입관(2) 고유의 진동주파수를, 주파수 필터부(B)로 출력하게 된다. 이어서, 각각의 고유범위가 다른 다수개로 조합된 주파수 필터부(B)에서 각 진동주파수 별로 분리하고, 부호화된 디지탈로 변환하는 A/D 변환기(C)를 거쳐, 중앙처리장치(D)에 출력하면, 중앙처리장치(D)에서는 입력된 신호를 미리 설정된 데이타와 비교, 분석하고, 이에 따른 동작지시를 흡입력 구동장치(E)와 동작상태표시부(F)로 출력케 된다.When the vacuum cleaner 1 is operated through a predetermined operating means, various dusts are sucked by the operation of the motor according to the operation. As shown in FIG. 2, the vacuum cleaner 1 is formed inside the suction pipe 2 of the vacuum cleaner 1. The dust sucked by the fixing protrusion 4 causes the vortex phenomenon in the same direction as the arrow "P" and vibrates the piezo film 3 which is a vibration sensing means embedded in the inner wall of the suction pipe 2. When applied, the vibration frequency obtained by dust and the vibration frequency inherent to the suction pipe 2 are output to the frequency filter part B. FIG. Subsequently, the frequency filter unit B, which is combined into a plurality of different inherent ranges, is separated for each vibration frequency, and is output to the central processing unit D through an A / D converter C for converting the encoded digital signal. Then, the central processing unit (D) compares and analyzes the input signal with the preset data, and outputs the operation instruction according to the suction force driving device (E) and the operation state display unit (F).

한편, 진동감지부(A)를 거쳐 출력되는 진동신호는 흡입관(2)의 고유진동수와 먼지 및 각종 불순물 등에 의해 얻어지는 진동주파수에 의해 결정되므로 흡입관(2)의 고유진동수와, 출력되는 진동신호가 동일하거나, 먼지 및 각종 불순물 등에 의해 얻어지는 진동주파수보다, 흡입관(2)의 고유진동수가 계속적으로 크게 출력되면, 흡입구가 막혀 피에조필름(3)을 진동토록 된 공기의 흡입량이 거의 없게 됨을 감지하고, 흡입구가 막힌 상태에서 동작중임을, 중앙처리장치(D)에서 판단하여 이를, 동작상태 표시부(F)를 통해 외부에 알리도록 하는 출력신호를 내보낸다(예를들어, 버저를 통한 경고음 발생 및, 동작정지에 따른 경고등 점등, 에러기호 및 문자를 디스플레이 한다).On the other hand, the vibration signal output through the vibration detection unit (A) is determined by the natural frequency of the suction pipe (2) and the vibration frequency obtained by dust and various impurities, etc., the natural frequency of the suction pipe (2) and the output vibration signal If the natural frequency of the suction pipe 2 is continuously larger than the vibration frequency obtained by the same or dust and various impurities, the suction port is blocked and the piezo film 3 is detected to have little suction amount of air. The central processing unit (D) determines that the inlet is operating in a blocked state, and outputs an output signal for notifying the outside of the operation state display unit (F) (for example, generating a warning sound through the buzzer, The warning lamp lights up and displays the error symbol and text according to the operation stop).

또한, 진공감지부(A)의 진동신호가 흡입관(2)의 고유진동수와, 먼지 및 각종 불순물 등에 의해 얻어지는 진동주파수의 양신호로 출력되면, 일반적인 청소상태임을 감지함과 동시에, 피에조필름(3)에 인가되는 불순물의 종류(예를들어, 흙모래, 또는 과자부스러기나 일반 먼지)에 따라 진동주파수의 크기도 변화하므로, 주파수 필터부(B)에서 진동신호를 입력받아 각 주파수대별로 분리하는 과정에서, 불순물의 종류 또한 분리, 파악되고, 파악된 내용의 신호가 A/D 변환기(C)에서 디지탈 신호로 변환되어, 중앙처리장치(D)에 입력되면, 중앙처리장치(D)에서는 이에 따른 적절한 청소상태를 유지하도록 흡입력 구동장치(E)에 지시신호를 내어 모터회전력을 증감시키므로, 청소범위에 따른 출력조절을 제어하도록 된 것이다.In addition, when the vibration signal of the vacuum detection unit (A) is output as both the natural frequency of the suction pipe (2), and the vibration signal obtained by the dust and various impurities, etc., it detects that the general cleaning state, the piezo film (3) Since the magnitude of the vibration frequency also varies depending on the type of impurities (for example, soil, confectionery, or general dust) applied to the filter, the frequency filter part B receives a vibration signal and separates it by each frequency band. When the type of impurity is also separated and identified, and the signal of the identified content is converted into a digital signal by the A / D converter C and input to the central processing unit D, the central processing unit D accordingly In order to maintain the cleaning state by sending an indication signal to the suction force driving device (E) to increase and decrease the motor rotation power, it is to control the output adjustment according to the cleaning range.

이상에서 본 바와 같이 진동감지수단인 피에조필름(3)에 의해 흡입관내의 진동주파수를 감지, 이를 분석하고, 청소하고자 하는 구역의 상태 등을 판단하여 이에 적합한 모터의 구동력을 조절하므로 진공청소기의 청소능력을 배가시키도록 된 것이다.As described above, the vibration sensor in the suction pipe is sensed and analyzed by the piezo film 3, which is a vibration sensing means, and the state of the area to be cleaned is determined to adjust the driving force of the motor suitable for the cleaning of the vacuum cleaner. It is to double the power.
