Description

물매트용 물보일러에서 소음방지 구조를 갖는 솔레노이드 밸브용 플런저 완충캡{Noise blocking packing for plunger of Solenoid valve}Noise blocking packing for plunger of solenoid valve with noise-proof structure in water boiler for water mat

본 발명은 물보일러에 솔레노이드 밸브가 내장되어 물길의 개폐를 조절하도록 하되, 상기 솔레노이드 밸브는 일측 플런저의 헤드 부분에 소음 저감용 완충캡이 결합되도록 함으로서, 조립된 물분배 캡의 개폐공의 물길 개폐시 열고 닫히는 순간 발생하는 접촉 소음을 차단하여 쾌적한 수면환경을 조성할 수 있도록 하는 것을 특징으로 하는 소음방지 구조를 갖는 솔레노이드 밸브 플런저용 완충캡에 관한 것이다.The present invention is provided with a solenoid valve in the water boiler to control the opening and closing of the waterway, the solenoid valve is to open and close the waterway of the opening and closing hole of the assembled water distribution cap by coupling the shock absorbing cap to the head portion of the plunger The present invention relates to a shock absorbing cap for a solenoid valve plunger having a noise preventing structure, which allows to create a comfortable sleeping environment by blocking contact noise generated at the moment of opening and closing.

이에 본 발명은 물분배용 개폐공과 맞닿는 접촉단부에 댐퍼 형식의 다단 접촉식 구조의 완충립과 충격감소판이 형성되어 충격소음을 최소화(완화 또는 방지)하는 반면 솔레노이드 밸브의 가압용 탄성스프링의 장력은 높게 유지할 수 있도록 하는 바, 이는 우수한 기밀(수밀)성이 확보되는 것을 특징으로 한다.Accordingly, the present invention provides a damper-type multi-stage contact structure and a shock reduction plate formed at a contact end contacting the opening / closing hole for water distribution to minimize (relax or prevent) shock noise, while the tension of the elastic spring for pressurizing the solenoid valve is The bar can be kept high, which is characterized by ensuring excellent airtightness (watertightness).

일반적으로 물매트란 물통에 저수된 물을 물보일러를 통해 순환시키도록 하되, 물보일러 내에 형성된 히터로 하여금 물을 가열시킨 후 발생한 온수가 매트본체에 내장된 순환호스에 공급되면서 그 가열 온도를 난방열로 사용하는 매트를 일컫는다.In general, the water mat is to circulate the water stored in the bucket through the water boiler, the hot water generated after heating the water by the heater formed in the water boiler is supplied to the circulation hose built into the mat body to heat the heating temperature Refers to the mat used as.

이러한 물매트는 전기 발열체가 내장된 기존의 전기매트의 문제점, 즉 유해 전자파 및 전기열선에 의한 화재나 감전 등의 위험성을 해소할 수 있게 되는 장점이 있다.Such a water mat has the advantage that it is possible to solve the problems of the existing electric mat in which the electric heating element is built, that is, the risk of fire or electric shock by harmful electromagnetic waves and electric heating wire.

한편, 종래의 물매트는 도 8에서와 같이 원난방, 투난방(분리난방) 구조로 구분되면서 사용되는데, 상기 물매트 사용시에는 사용자가 맞춤 온도(물온도의 도달온도)를 설정하면 물보일러에 장착된 솔레노이드 밸브가 열린 상태를 유지하면서 물의 순환을 조장하게 되고, 이후 설정온도에 도달하게 되면 솔레노이드의 개폐밸브 플런저가 물분배캡의 개폐공을 닫으면서 물길을 막도록 형성된다.On the other hand, the conventional water mat is used while being divided into the heating and the heating (separated heating) structure as shown in Figure 8, when using the water mat when the user sets the custom temperature (water temperature reached temperature) to the water boiler The installed solenoid valve maintains the open state to encourage the circulation of water, and when the set temperature is reached, the on / off valve plunger of the solenoid is formed to close the opening while closing the opening and closing hole of the water distribution cap.

이때, 상기 플런저는 도 7에서와 같이 외주면 일측 단부에 코일스프링이 장착되어 상시 개폐공을 막도록 장력이 발휘되는데, 개폐공의 열림을 위해 전자석 ON 가동시에는 플런저가 후방으로 밀리면서 개폐공을 열게 된다.At this time, the plunger is provided with a coil spring at one end of the outer circumferential surface as shown in FIG. 7 to exert tension to prevent opening / closing holes at all times. Open.

그러나, 물의 온도가 설정온도에 도달하게 되면 상기 전자석은 OFF가 되면서 잡아당겼던 플런저를 놓게 되는데 이때 코일스프링의 장력은 플런저를 홈으로부터 밀어내면서 외측 단부가 개폐공을 닫도록 형성된다. However, when the temperature of the water reaches the set temperature, the electromagnet is turned off to release the plunger pulled, wherein the tension of the coil spring is formed so that the outer end closes the opening and closing hole while pushing the plunger out of the groove.

다시 말해, 상기 코일스프링은 장력이 높을 경우 플런저의 닫음시 수밀성, 기밀성을 높게 확보할 수 있으나 솔레노이드 밸브의 ON 구동후 후방으로 밀렸던 플런저가 전자석 OFF가 되면 코일스프링의 장력으로 하여금 개폐공을 향해 돌진하듯 밀착되어 "땅" 하는 충격 소음이 발생하게 된다.In other words, the coil spring can ensure high watertightness and airtightness when the plunger is closed when the tension is high, but when the plunger pushed backward after the solenoid valve is turned on, the electromagnet is turned off, the tension of the coil spring rushes toward the opening and closing hole. It will come in close contact and create "ground" impact noise.

이를 해소하기 위해 종래에는 납작한 원판형의 패킹을 부착하여 이를 해소하고자 하였으나, 개폐공과 닿는 면적이 민자이고 플런저의 외측단부에 대하여 원통체 형태로 결합된 종래의 패킹은 충격소음을 크게 감소시키지 못해 소음이 계속되고 있는 실정이다. Conventionally, in order to solve this problem, a flat disk-shaped packing was attached to solve the problem. However, the conventional packing, which has an area of contact with the opening and closing hole and is combined in the form of a cylindrical body with respect to the outer end of the plunger, does not significantly reduce the impact noise. This situation continues.

즉, 이러한 충격 소음은 낮시간(주간)은 물론 야간 취침 중에도 빈번하게 발생하게 됨으로서, 사용자는 물론 이웃 주거 세대에도 적지 않은 소음 민원을 초래하고 있는 실정이다. In other words, the impact noise is frequently generated during the daytime (daytime) as well as during bedtime, causing a lot of noise complaints not only to users but also to neighboring residential generations.

다음은 첨부된 도면을 참조하며 본 발명을 보다 상세히 설명하겠다.The following describes the present invention in more detail with reference to the accompanying drawings.

먼저, 도 1 내지 도 6에 도시된 바와 같이, 본 발명은 탄성 지지체(100)를 기준으로 상측에는 연질형 완충립(200)이 형성된다.First, as shown in Figures 1 to 6, the present invention is based on the elastic support 100, the soft buffer lip 200 is formed on the upper side.

이에, 상기 완충립(200)은 납작한 원판 형태로서 완충립(200)의 직경보다 좁은 직경의 연결대(300)에 의해 탄성 지지체(100) 상면과 일체로 결합되도록 형성된다.Thus, the buffer lip 200 is formed to be integrally coupled to the upper surface of the elastic support 100 by a connecting rod 300 of a diameter smaller than the diameter of the buffer lip 200 in the form of a flat disk.

즉, 상기 탄성 지지체와 연결대 및 완충립 그리고 후술되는 충격감소판 모두 연질 실리콘 재질로 된 일체형 구조로서 전부 상하방향 텐션이 확보되면서 전체 물성이 신축되도록 형성된다.That is, the elastic support, the connecting rod, the buffer lip, and the impact reducing plate to be described below are all formed as a unitary structure made of a soft silicon material, so that all the upper and lower tensions are secured so that the entire physical properties can be stretched.

이에, 상기 완충립(200)은 상면부에 압착면(210)이 형성되도록 하되, 상기 압착면(210)은 측단면을 기준으로 깔대기 형상 또는 접시 형상으로 형성되는 것이 바람직하다.Thus, the buffer lip 200 is to be formed on the upper surface of the pressing surface 210, the pressing surface 210 is preferably formed in a funnel shape or plate shape based on the side cross-section.

즉, 상기 압착면(210)은 물개폐공(20)과 대응시 중앙부가 물개폐공 내부로 역으로 솟으면서 원뿔형태로 상부로 돌출된 면 일부가 압착되도록 형성된다. 이는 닫힐 때 소음을 방지하면서 수밀성을 강화시키기 위함이다.That is, the pressing surface 210 is formed so that the portion of the surface protruding upward in the shape of a cone is compressed when the center portion rises back into the seal opening hole in correspondence with the seal opening 20. This is to enhance the watertightness while preventing noise when closing.

이때, 압착면을 갖는 완충립이 시옷자로 꺽이면서 개폐공에 들어가면 연결대도 일부 압축되면서 신축하게 되고 이는 탄성지지체와 함께 뒤로 밀림으로서, 소음을 단계별로 감소시키도록 형성된다.At this time, when the cushioning lip having a compression surface enters the opening and closing hole by bending the sieve, the connecting table is also partially compressed and stretched, which is pushed back together with the elastic support, and is formed to reduce the noise step by step.

즉, 상기 연결대(300)는 완충립(200)이 후방으로 밀리면 동시에 상하 신축되면서 탄성 압축되도록 형성된다.That is, the connecting table 300 is formed to elastically compress while simultaneously stretching up and down when the buffer lip 200 is pushed backward.

이때, 상기 탄성 지지체(100)의 하측에는 충격감소판(400)이 형성되도록 하되, 상기 충격감소판(400)의 저면에는 접촉돌출면(500)이 돌출되도록 형성된다.At this time, the impact reducing plate 400 is to be formed on the lower side of the elastic support 100, the bottom surface of the impact reducing plate 400 is formed so that the contact projection surface 500 protrudes.

이에, 상기 충격감소판(400)은 연질 형태로서 탄성력에 의해 외측 날개면이 상하 신축되도록 형성된다.Thus, the impact reducing plate 400 is formed in a soft form so that the outer wing surface is stretched up and down by the elastic force.

또한, 상기 탄성 지지체(100)는 내부측에 결합홈(110)이 형성되어 저면 개구공(120)을 관통한 플런저(10)의 상단부 결합턱(11)이 대응되면서 삽입 고정될 수 있도록 형성된다.In addition, the elastic support 100 is formed so that the coupling groove 110 is formed on the inner side so that the upper end coupling jaw 11 of the plunger 10 penetrating the bottom opening hole 120 can be inserted and fixed. .

이때, 상기 충격감소판(400)은 하부면에 접촉돌출면(500)으로부터 분기된 돌기띠(600)가 다수 형성되어 플런저의 인출공(30) 단부에 압착시 공기틈을 확보하여 소음을 방지하되, 완전 압착(진공 밀폐)이 방지되어 플런저 상승시 발생하는 소음을 차단하도록 형성된다.At this time, the impact reducing plate 400 is formed on the bottom surface is formed with a plurality of projection strips 600 branched from the contact protrusion surface 500 to secure the air gap when pressing the end of the outlet hole 30 of the plunger to prevent noise However, the complete compression (vacuum seal) is prevented is formed to block the noise generated when the plunger rises.

즉, 상기 인출공의 단부와 실질적으로 맞닿는 접촉돌출면은 상하 압축되도록 하되, 돌기띠 역시 납작하게 압축될 수 있도록 함으로서, 기밀은 확보하되 추후 이격될 때는 진공압착되지 않도록 함으로서 닫힘 동작에서의 소음이 발생하지 않도록 형성된다.That is, the contact protruding surface substantially in contact with the end of the outlet hole is to be compressed up and down, but also the projection belt can be compressed evenly, to ensure the airtight but not to be vacuum-pressed when later spaced away noise in the closing operation It is formed so as not to occur.

본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 고안이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims.
