본 고안은 초음파 세척기등에 사용하며 BLT형 진동자의 공진특성을 개선하여 동시다주파를 발생시킬 수 있도록 한 다주파용 진동자에 관한 것이다.The present invention relates to a multi-frequency vibrator used in an ultrasonic cleaner, etc. to improve the resonance characteristics of the BLT type oscillator to generate simultaneous multi-frequency.
일반적으로 초음파는 주파수가 20KHz 이상인 음파를 의미하는 것으로 그것의 여러가지 물리학화학적인 작용을 이용하여 초음파 세척기, 용착기 및 의료용 진단기능을 만드는데 사용한다.In general, ultrasonic waves refer to sound waves having a frequency of 20 KHz or more, and are used to make ultrasonic cleaners, welding machines, and medical diagnostic functions using various physicochemical actions.
초음파 발생기는 고주파 전기신호를 발생하는 발진장치와 전기신호를 초음파로 변환하는 진동자로 구성되어 있다.The ultrasonic generator is composed of an oscillator for generating a high frequency electrical signal and a vibrator for converting the electrical signal into ultrasonic waves.
초음파 진동을 일으키는 소자로는 자왜효과를 이용한 자왜진동자와 압전효과를 이용한 압전진동자가 있다.The devices that generate ultrasonic vibration include magnetostrictive vibrators using magnetostrictive effects and piezoelectric vibrators using piezoelectric effects.
압전효과는 수정등의 결정체에 전기적인 진동이 가해질때 그에 대응하는 기계적 진동이 발생하는 현상을 의미한다.The piezoelectric effect refers to a phenomenon in which mechanical vibrations corresponding to electrical vibrations are applied to crystals such as crystals.
이러한 효과를 나타내는 물질을 압전체 혹은 압전물질이라 하고, 이러한 압전체로는 수정, PZT(티탄산 지르콘산 납화화물 세마릭; PZT라 칭함)등이 있다.Substances having such an effect are referred to as piezoelectric or piezoelectric materials. Examples of such piezoelectric materials include quartz and PZT (zirconate zirconate titanate semaric; referred to as PZT).
초음파 세척기에는 28KHz와 40KHz의 진동자가 사용되고 있다.Ultrasonic cleaners with 28KHz and 40KHz oscillators are used.
이 진동자들은 하나의 원형 블록에 전극과 압전소자, 밸메스 등을 순차적으로 결합한 형상의 것으로 단일 주파수의 기계적 공진을 일으키는 원리로 되어 있다.These vibrators are formed by sequentially combining electrodes, piezoelectric elements, and valmes in one circular block, and have the principle of causing mechanical resonance at a single frequency.
이 방식의 진동자는 부하에 의해 공진주파수가 크게 변할 뿐더러 정재파 현상(Standing Wave)을 일으키는 단점이 있다.This type of oscillator has a disadvantage in that the resonance frequency is greatly changed by the load and also causes a standing wave.
정재파 현상은 초음파의 방사면에서 부터 진행하는 파와 수면에서 반사되는 파가 간섭하여 발생하는 것이다.The standing wave phenomenon is caused by the interference between the wave propagating from the radiation plane of the ultrasonic wave and the wave reflected from the water surface.
이 현상에 따라 세정조내에서 초음파가 불균일하게 되고 수심변동에 따라 전체적인 초음파 출력이 민감하게 변한다.According to this phenomenon, the ultrasonic waves become uneven in the cleaning tank, and the overall ultrasonic power changes sensitively as the water depth fluctuates.
따라서, 본 고안의 목적은 상기와 같은 종래의 제반 문제점을 해결하기 위하여 안출된 것으로, 기존 진동자의 블록 구조를 원형에서 장방형으로 개선하고 한개의 공진 블록을 2개의 공진블록으로 바꿈으로써 종진동, 횡진동을 포함한 복합진동을 일으키도록 하고, 하나의 진동자로 40∼90KHz까지 다양한 초음파를 동시에 만들어 낼 수 있도록 한 것이다.Therefore, the object of the present invention was devised to solve the conventional problems as described above, longitudinal vibration, lateral by improving the block structure of the existing vibrator from circular to rectangular and replacing one resonant block with two resonant blocks It is intended to generate complex vibrations including vibrations, and to simultaneously produce various ultrasonic waves up to 40 ~ 90KHz with one oscillator.
먼저, 도시된 제1도에 의하여 설명한다.First, a description will be given with reference to FIG. 1.
도시된 제1도는 본 고안의 분해사시도로서, 장방형의 방사바(Radiating Bar)(1)의 양측에 두 체결공(2)을 나란히 형성하고, 양측 각각에는 제1전극판(Electrode)(3)과 제1압전소자(PZT Element)(4), 제2전극판(5)과, 제2압전소자(6), 백메스(Back mass)(7) 및 압축와셔(Compression Washers)(8)의 공진블럭을 순차적으로 결합하되, 결합하는 수단으로는 상기의 결합 구조물들에 삽입공(9)을 각각 형성하고 이에 절연부시(10)를 삽입한 다음 체결볼트(11)로써 관통시켜 상기의 체결공(2)에 각각 체결고정하여 구성한 것이다.1 is an exploded perspective view of the present invention, in which two fastening holes 2 are formed side by side on both sides of a rectangular radiating bar 1 and a first electrode plate 3 on each side thereof. Of the first piezoelectric element (PZT element) 4, the second electrode plate 5, the second piezoelectric element 6, the back mass 7 and the compression washers 8; The resonance blocks are sequentially coupled, but as a means for coupling, insertion holes 9 are formed in the coupling structures, and the insulating bush 10 is inserted into the coupling blocks, and then the coupling holes 11 are penetrated through the fastening holes 11. It is composed by fastening and fastening in (2) respectively.
이상과 같이 구성된 본 고안은 제1 및 제2전극판(3),(5)에 전원이 인가되면 이들 제1 및 제2전극판(3),(5)에 접하게 결합되고 세라믹재로된 제1 및 제2압전소자(4),(6)가 기계적 진동을 일으키게 되며, 이에 따라 백메스(7)와 방사바(1)가 공진을 일으켜 강한 초음파를 발생시킨다.The present invention configured as described above is made of a ceramic material coupled to the first and second electrode plates 3 and 5 when power is applied to the first and second electrode plates 3 and 5. The first and second piezoelectric elements 4 and 6 generate mechanical vibrations, and thus the back scalpel 7 and the radiation bar 1 generate resonance to generate strong ultrasonic waves.
이때 방사바(1)는 장방형의 구조를 가지고 있으므로 단일주파수공진이 일어나는 대신 복합적인 주파수 공진이 일어난다.At this time, since the radiation bar 1 has a rectangular structure, a complex frequency resonance occurs instead of a single frequency resonance.
또한 2개의 제1 및 제2압전소자(4),(6)를 동일 방사바(1)에 양측으로 나란히 결합함으로써 종진동, 횡진동을 포함한 복합진동이 발생하게 된다.In addition, by combining two first and second piezoelectric elements 4 and 6 side by side on the same radiation bar 1 on both sides, a complex vibration including longitudinal vibration and lateral vibration occurs.
이에 따라 다양한 복합주파수의 초음파 발생이 이루어지게 되는 것이다.Accordingly, the generation of ultrasonic waves of various complex frequencies is achieved.
이와 같은 본 고안의 진동자는 실험에 의하면, 주파수 응답특성이 평탄하며 전압, 전류위상이 넓은 범위에서 일정하여 발진기의 신뢰성이 크게 향상되고, 또한 본 고안의 진동자에서는 정재파 현상이 거의 나타나지 않았으며 수심에 따라서도 출력의 변동폭이 30%이내 이었다(종래에는 70% 이상 이었음).According to the experiment, the vibrator of the present invention has a flat frequency response characteristic and a constant voltage and current phase in a wide range, which greatly improves the reliability of the oscillator. Therefore, the fluctuation of the output was within 30% (previously 70% or more).
이상과 같은 본 고안의 진동자는 초음파 세척기용으로 적합하다.The vibrator of the present invention as described above is suitable for an ultrasonic cleaner.
본 고안의 진동자를 세척기에 적용시켜 사용하는 실시예를 도시된 제2도와 제3도에 의하여 설명한다.An embodiment using the vibrator of the present invention applied to a washing machine will be described with reference to FIGS. 2 and 3.
세척액(12)이 내장되는 세척용기(13)의 밑판(14)에 에폭시 접착제와 같은 특수접착제와 자동가열로 등에 의하여 방사바(1)를 부착한다.The spinning bar 1 is attached to the bottom plate 14 of the cleaning container 13 in which the cleaning solution 12 is embedded by a special adhesive such as an epoxy adhesive and an automatic heating furnace.
이와 같은 초음파 세척기는 제1 및 제2전극판(3),(5)에 전원을 인가시키면 상기에서 상세히 설명한 바와 같은 작용원리에 의하여 초음파를 발생시키게 되며, 발생된 초음파는 세척용기(13)로 전달된다.When the ultrasonic cleaner is applied with power to the first and second electrode plates 3 and 5, the ultrasonic cleaner generates ultrasonic waves according to the operating principle described in detail above, and the generated ultrasonic waves are transferred to the washing container 13.
