자동 습도조절 악기 케이스{Portable Case for a Musical instrument, with Automatic humidity controller} Portable Case for a Musical instrument, with Automatic humidity controller

악기 케이스, 습도조절장치Instrument Case, Humidity Controller

바이올린 등의 악기는 전통적으로 나무로 만들어지기 때문에 습도에 민감하여 습도조절이 매우 중요하다. 특히 대한민국은 사계절의 변화가 크므로 더욱 습도 조절에 유의해야한다.       Since musical instruments such as violins are traditionally made of wood, humidity control is very important because they are sensitive to humidity. In particular, the Republic of Korea has a big change in the four seasons, so be careful to control the humidity.

악기를 만들 때 접착성분은 특성상 물에 녹는 성질을 가지고 있어 건조한 겨울철과 습한 여름철에 습도의 정도에 따라서 악기를 보관하는 방법이 다르다. 바이올린의 경우 종류에 따라 약간의 차이가 있을 수 있지만 일반적인 적정 습도는 50%에서 60%가 가장 이상적이다. 원목이 합판에 비해 습도에 더 취약하여 시간이 지날수록 온도와 습도 자체적인 영향으로 계속 변형이 될 수 있다. 또한 나무의 뒤틀림이 가장 큰 치명적 경우라 할 수 있다. 오래 건조를 시켜서 나무가 더 이상 뒤틀릴 수 없을 만큼 많이 뒤틀리게 만든 스트레스 공법으로 만든 악기도 있다. 나무가 뒤틀리면 줄을 조절해도 튜닝이 안되고 소리 자체가 불안해 질 수도 있고 피치가 불안해지고 버징이 심해질 수 있다. 따라서 바이올린 케이스에 습도계를 비치 해두고 물을 넣어 습도를 대략적으로 조절하는 제품이 판매되고 있다.When making musical instruments, the adhesive component is water-soluble, so the method of storing the instrument differs depending on the humidity level in dry winter and wet summer. The violin may vary slightly depending on the type, but the ideal humidity is usually 50% to 60%. Logs are more vulnerable to humidity than plywood, so they can continue to deform over time due to their own effects on temperature and humidity. The warping of trees is also the most deadly case. Some instruments are made with a stress method that has been dried for a long time, causing the tree to warp so much that it can no longer be twisted. If the tree is warped, adjusting the strings will not tune, and the sound itself may become unstable, the pitch may be unstable, and the buzzing may be severe. Therefore, there is a product that has a hygrometer on the violin case and adds water to control the humidity.

습도를 측정하는 장치는 크게 기계적 습도계와 전기적 습도계 두 가지가 있다. 기계적 습도계는 유기물질들이나 머리카락과 같은 단백질 또는 플라스틱이 상대습도에서 수축하거나 팽창하는 원리를 이용해 아날로그 눈금으로 나타낸 것이다. 전기 습도계는 상대 습도에 따라서 염화 리튬 (LiCl)의 얇은 층이나 반도체소자의 전기저항이 변하는 정도에 따라 디지털화시킨 것이다. 이 밖에도 이슬점을 이용하거나 건구 습구의 온도차를 비교해서 상대 습도를 나타내는 여러 가지 습도측정 장치가 있다.There are two types of humidity measuring devices, mechanical hygrometer and electrical hygrometer. Mechanical hygrometers are displayed on an analog scale using the principle that organic materials, proteins or plastics such as hair or plastic contract or expand at relative humidity. An electric hygrometer is digitized according to the relative humidity of a thin layer of lithium chloride (LiCl) or the electrical resistance of a semiconductor device. In addition, there are several humidity measuring devices that use a dew point or compare the temperature difference between dry bulbs and wet bulbs.

바이올린 등의 악기 케이스 안에 습도를 일정하게 유지시킬 수 있는 장치로써 한쪽에는 물이 수분 흡수 플라스틱에 흡수되어 젤 상태로 유지하게 하고 다른 한쪽에는 건조제가 들어 있어서 습도가 일정 수치보다 높아질 경우 이쪽의 밸브가 열려서 습도를 조절할 수 있게 한다. 이러한 밸브들의 개폐를 전자 습도기 장착에 의한 전기적 신호를 감지해서 습도가 일정 수치 이상일 경우는 물이 담겨있는 쪽의 밸브가 닫히고 건조제 부분의 밸브가 열리는 방식으로 습도 센서에 의한 피드벡 방식으로 습도유지를 일정하게 유지할 수가 있다. 하지만 전자 회로를 이용해 이 장치를 사용하기 위해서는 전원이 계속해서 공급되어야 하는 불편함이 발생하므로 이에 대한 방편으로써 전원을 사용하지 않으면서 밸브가 작동될 수 있는 새로운 방식이 필요하다.        It is a device to keep the humidity in the instrument case such as a violin. Water is absorbed by water-absorbing plastic on one side to keep it in a gel state, and on the other side, the desiccant contains the valve. Open to control humidity. When the humidity is above a certain value by detecting the electrical signal by installing the electronic humidifier, the valves on the side of the water are closed and the valve on the desiccant part is opened. Can be kept constant. However, the use of this device with electronic circuits creates the inconvenience of having to continue to supply power, which requires a new way to operate the valve without using power.

밸브에 습윤 팽창율 (hygroscopic expansion)이 높은 셀로판지 PET 필름(poly-ethylene terephthalat )을 여러 겹 겹쳐서 말아 놓게 되면 습도가 높아지면 늘어나고 낮아지면 당겨지는 장력을 이용해서 밸브들을 열고 닫을 수 있는 방식의 습윤 팽창 개폐 방식의 습도 유지 장치를 만들 수 있다. 또한 모발의 경우 습도가 높아지면 모발이 약 13% 이상 팽창하여 모발 습도계에 널리 사용되고 있다. 이 모발을 이용하면 역시 습윤 팽창 개폐 방식의 습도 유지 장치를 만들 수 있다.        Multiple layers of cellophane PET film (polyethylene terephthalat) with high hygroscopic expansion on the valve can be rolled up and closed to open and close the valves using tension that increases when the humidity increases and when the humidity decreases. It is possible to make a humidity maintaining device. In addition, in the case of hair, when the humidity increases, the hair expands about 13% or more and is widely used in the hair hygrometer. This hair can also be used to create a wet expansion and humidity control device.

습윤 팽창률이 열팽창률에 비해 훨씬 큰 물질들을 선정해서 습도에 따라 어느 정도 늘어날지 수축할지에 대한 실험과 여러 습윤 팽창률이 다른 시료들을 일정한 크기의 모양으로 가공하여 밸브를 움직일 수 있는 최소한의 힘을 얻기 위해서는 어느 정도의 길이나 두께인지를 실험해 본 결과, PET 필름과 모발이 가장 안정적이었다. Select materials whose wet expansion rate is much larger than the thermal expansion rate to determine how much they will increase or shrink with humidity, and process samples with different wet expansion rates to a certain size to obtain the minimum force to move the valve. In order to test the length and thickness, the PET film and hair were the most stable.

본 발명은 기존의 전기적인 자동 습도조절장치가 전기를 사용하기 위해 건전지를 교체해야 하는 불편함을 제거해 준다. 또한 본 발명은 악기 케이스뿐만 아니라 반영구적이고 전기 공급이 필요하지 않은 자동 습도조절 장치가 필요한 어떤 환경에도 사용이 가능하여 폭넓은 응용이 가능하다.The present invention eliminates the inconvenience of having to replace the battery in order to use the existing electric automatic humidity control device. In addition, the present invention can be used in any environment that requires a semi-permanent, automatic humidity control device that does not require electricity supply, as well as a musical instrument case is possible for a wide range of applications.

2 is a perspective view of the present invention

본 발명은 외부의 전기 공급없이 자동으로 밸브나 구멍이 자동으로 개폐되는 장치를 구성하고 있다. 도 2는 본 발명의 자동 습도조절장치(1-2) 일실시예 사시도로 모발(2-6)이나 PET의 습윤 팽창 성질을 이용한 것이다.        The present invention constitutes an apparatus in which a valve or a hole is automatically opened and closed without an external electric supply. Figure 2 is a perspective view of an embodiment of the automatic humidity control device 1-2 of the present invention using the wet expansion properties of the hair (2-6) or PET.

본 발명의 작동원리를 보다 상세하게 설명하면 다음과 같다. 악기 케이스 안에 습기가 많아지면 모발 감개(2-5)에 감겨져 있는 모발의 팽창이 일어나 길이가 늘어 나는데 이를 반대쪽에 장착되어 있는 스프링(2-4)이 잡아 당기게 된다. 이때 제습조절 창(2-7)이 반대쪽으로 움직이게 되어 제습창(2-10)이 열리게 된다. 제습창(2-10)이 열리면 제습장치(2-3)가 악기 케이스(1-1) 안의 습기를 제거한다. 반대로 악기 케이스(1-1) 안이 건조하게 되면 모발 감개(2-5)에 감겨져 있는 모발(2-6)이 수축하게 된다. 이때 모발 감개에 부착된 스프링(2-11)이 모발 감개쪽으로 제습조절 창(2-7)을 당겨 주고 가습창(2-9)이 열려 가습장치(2-2)에서 악기 케이스(1-1) 안에 습기를 공급해 주게 된다.        Referring to the principle of operation of the present invention in more detail as follows. When the moisture in the instrument case increases, the hair wound around the hair reel (2-5) is expanded and the length is increased, and the spring (2-4) mounted on the opposite side is pulled out. At this time, the dehumidification control window (2-7) is moved to the opposite side to open the dehumidification window (2-10). When the dehumidification window (2-10) is opened, the dehumidifier (2-3) removes moisture in the instrument case (1-1). On the contrary, when the inside of the musical instrument case 1-1 is dried, the hair 2-6 wound on the hair reel 2-5 is contracted. At this time, the spring (2-11) attached to the hair reel pulls the dehumidification control window (2-7) toward the hair reel and the humidification window (2-9) is opened to open the instrument case (1-1). Will be moisturized.

상기와 같은 작동원리로 된 본 발명의 자동 습도조절장치(1-2)는 별도의 수분을 공급해 주는 일 없이 제습장치(2-3)의 수분을 그대로 사용할 수도 있다.        Automatic humidity control device (1-2) of the present invention as described above may use the moisture of the dehumidifier (2-3) without supplying additional moisture.

모발의 인장력 정도로 충분히 당길 수 있는 무게를 가진 재질은 많이 있으므로 제습조절 창(2-7)을 원하는 정도의 무게와 경도를 가진 재질로 만들 수 있다.        Since there are many materials with enough weight to pull the hair enough to tension, the dehumidification control window (2-7) can be made of a material with the desired weight and hardness.

또한 본 발명에서 모발을 PET로 대체하여도 원하는 효과를 달성할 수 있다.          In addition, in the present invention, replacing the hair with PET can achieve the desired effect.
