본 발명은 충진제가 수납된 채로 외곽내부의 공기만을 배기시켜서 속이 비어 있는 형상으로 되는 진공단열패널에 관한 것이다.The present invention relates to a vacuum insulation panel in which only the inside of the outer air is exhausted while the filler is stored, thereby becoming hollow.

종래에는 이러한 종류의 진공 단열 패널로서 가스벽성 필름(gas barrier 性 film)을 주머니 형상으로 형성한 외곽내에 통기성이 있는 직물 또는 종이 재질의 안주머니에 피얼라이트(pearlite) 분말 등의 분말체를 수용한 충진체를 수납하고 이 수납상태에서 외곽의 내부로부터 공기를 배기시켜서 밀폐되게 밀봉하고 이로써 내부를 진공상태로 유지하도록 구성한 것이 제공되고 있었다.Conventionally, this type of vacuum insulation panel is filled with a powder such as pearlite powder in a breathable fabric or paper inner pocket in a gas barrier film formed in a bag shape. It has been provided that the sieve is stored and sealed in such a state that the air is evacuated from the inside of the outer enclosure to be hermetically sealed, thereby maintaining the interior in a vacuum state.

그러나 전술한 구성에서는 외곽의 내부 즉 충진제의 배기를 행할 때 안주머니를 거쳐서 분말체간의 공기를 배출케하므로 공기가 안주머니를 통과할 때에 받는 저항이 크기 때문에 배기에 요하는 시간이 길어진다는 결점이 있었다.However, the above-described configuration has a drawback in that the time required for the exhaustion is increased because the resistance received when the air passes through the inner pocket is large because the air between the powders is discharged through the inner pocket when exhausting the inside, that is, the filler.

한편 배기시간을 단축하기 위해서 안주머니의 두께를 얇게 하여 통기성을 높이게 되면 분말체가 안주머니를 통과해서 진공펌프 내로 흡인되어 진공펌프를 손상시킬 염려가 있었다.On the other hand, in order to shorten the exhaust time, if the thickness of the inner pocket is increased to increase the air permeability, the powder may be sucked into the vacuum pump through the inner pocket and damage the vacuum pump.

또한 분말체의 평균입자 지름은 통상 10-20μ정도이므로 이와 같은 분말제를 취급하는 경우 그 작업성이 나쁘며 또한 안정 위생상으로도 문제가 많았었다.In addition, since the average particle diameter of the powder is usually about 10-20 µm, when the powder is handled, its workability is poor and there are many problems in terms of stable hygiene.

본 발명은 상기와 같은 문제점에 비추어서 확이하여 된 것으로서 그 목적은 외곽의 내부에서 공기를 배기시킬 때에 배기의 소요시간을 단축할 수 있음과 동시에 충진체인 분말체가 외부로 새어 나가게 되는 것을 방지할 수가 있으며, 더욱이 취급 작업성을 향상시킬 수 있는 등 여러가지 우수한 효과를 나타내는 진공단열패널을 제공하고저 하는데 있다.The present invention has been made in view of the above problems, and the object thereof is to shorten the time required for exhausting the exhaust air from the outside and prevent the powder from leaking out to the outside. In addition, to provide a vacuum insulation panel exhibiting various excellent effects, such as to improve the handling workability.

본 발명은 외곽의 내부에 수납되는 충진체인 분말체를 가압해서 서로 결합시킴으로써 형성된 다공질 성형체로 구성시킨 것에 특징이 있으며 이로써 종래에는 필요로 하였던 안주머니를 불필요하게 한 것이다.The present invention is characterized in that it is composed of a porous molded body formed by pressing the powder body, which is a packing body contained in the outer part, and bonding them to each other, thereby eliminating the need for the inner bag required in the prior art.

다음에 본 발명의 한 실시예에 관해서 도면을 참조하면서 설명하자면 제 2 도에서 "1"은 속이 빈 형상의 외곽으로서 이것은 예를 들면 표면에 금속 증착층이 있는 폴리에스텔등으로 만들어지는 가스벽 성의 필름을 용기 형상으로 형성해서 구성되어 있다.In the following, an embodiment of the present invention will be described with reference to the drawings. In FIG. 2, "1" is a hollow outer shape, for example, a gas wall property made of polyester or the like having a metal deposition layer on its surface. The film is formed in a container shape and is configured.

"2"는 외곽(1)의 내부에 수납되어 있는 충진체로 이것은 예를 들면 규산칼슘 판상 결정분말(상품명 「후로라이트 R」: 도꾸야마 소오다 주식회사제, 평균 입자 지름 20μ)로 된 분말체를 예를 들면 100kg/㎠의 압력으로 가압해서 서로 결합시킴으로써 평판상으로 형성되어 있는 다공질 성형체로 구성되어 있다."2" is a packing body which is stored inside the outer part 1, for example, the powder body which consists of calcium silicate plate crystal powder (brand name "Florite R: Tokuyama Soda Co., Ltd., average particle diameter 20 micrometers). For example, it consists of the porous molded object formed in flat form by pressurizing at the pressure of 100 kg / cm <2>, and bonding together.

그리고 이와 같은 충진체(1)가 외곽(2)내에 수납된 상태의 것을 제 1 도에 나타낸 바와 같이 진공용기(3)내에 수용함으로써 외곽(1)에 형성된 배기구(1a)를 거쳐서 외곽(1)의 내부의 공기가 배기되어진다.As shown in FIG. 1, the filling body 1 is accommodated in the outer space 2, and the outer space 1 is provided through the exhaust port 1a formed in the outer space 1 by accommodating the inside of the vacuum container 3 as shown in FIG. The air inside is exhausted.

이 경우 진공용기(3)의 내부는 도시하지 않은 진공펄프에 의해 배기구(3a)에서부터 진공되므로써 예를 들면 1torr 정도로 감압되게 되어 있다.In this case, the inside of the vacuum container 3 is reduced in pressure, for example, about 1 torr by vacuuming from the exhaust port 3a by a vacuum pulp not shown.

진공용기(3)내부 즉 외곽(1)의 내부가 1torr 정도로 배기된 후 히팅시일러(heating sealer)(4)에 의해서 외곽(1)의 배기구(1a)를 용착해서 외곽(1) 내부를 밀폐되게 밀봉한다.After the inside of the vacuum container 3, that is, the inside of the outside 1 is exhausted about 1 torr, the exhaust port 1a of the outside 1 is welded by a heating sealer 4 to seal the inside of the outside 1. Seal it.

이와 같은 구성의 본 실시예에 의하면 충진체(2)를 분말체를 가압해서 서로 결합시킴으로써 형성된 다공질 성형체를 구성하였으므로 종래와는 달리 안주머니를 통해서 배기되는 일이 없어지며 배기 소요시간을 단축시킬 수가 있다.According to this embodiment of such a configuration, since the porous body formed by pressing the powders 2 together by pressing the powders is constituted, unlike the related art, the exhaust body is not exhausted through the inner pocket and the exhaust time can be shortened. .

더욱이 이와 같은 분말체를 가압해서 형성된 다공질 성형체로 충진체(2)를 구성하였으므로 종래의 안주머니에 분말체를 수용하는 것에 비해서 분말체가 새어나오는 것을 거의 방지할 수가 있으며, 이 결과 분말체가 진공 배기계통 특히 진공펌프로 흡인되는 것을 방지할 수가 있으므로 진공배기 계통의 보수 관리 및 진공 펌프의 손상을 감소시킬 수가 있다.Furthermore, since the filling body 2 is formed from the porous molded body formed by pressing such powder, it is almost impossible to prevent the powder from leaking out compared to accommodating the powder in a conventional inner pocket. Since the vacuum pump can be prevented from being sucked, the maintenance of the vacuum exhaust system and the damage of the vacuum pump can be reduced.

또한 분말체가 새어나오는 것이 거의 방지되므로 분말체가 외곽(1)의 용착 부분에 부착되는 일이 없어지며 외곽의 용착시에 용착부분에 이 물질이 끼어서 가스누설이 생기는 것을 방지할 수가 있으며 용착부분에 있어서의 가스벽성 및 용착강도를 향상시킬 수가 있다.In addition, since the powder is almost prevented from leaking, the powder is not attached to the welded portion of the outer shell 1, and when the outer welding is carried out, this substance can be caught in the welded portion to prevent gas leakage. Can improve gas wall properties and welding strength.

또한 외곽(1) 내부의 배기시에 분말체가 새어나오는 일이 거의 없으므로 강력한 진공펌프를 사용해서 배기속도를 상승시킬 수가 있으며 제조의 신속화 및 제조 가격의 저감을 도모할 수 있다.In addition, since there is almost no leakage of powder during exhaust of the interior 1, a powerful vacuum pump can be used to increase the exhaust speed, and the manufacturing speed and the manufacturing cost can be reduced.

덧붙여서 충진체(2)가 다공질 성형체이므로 종래에 비해서 보다 안전 위생적이고 취급의 작업성이 향상된다.In addition, since the filling body 2 is a porous molded body, it is more safe and hygienic than the conventional one, and the workability of handling improves.

더욱이 앞에서도 기술한 바와 같이 분말체를 가압해서 서로 결합시킴으로써 충진체(2)를 구성하므로 분말체간의 틈새가 작아지므로 외곽(1)에 가스누설이 발생해서 외곽(1) 내부의 압력이 상승하여도 열전도율의 변화가 작게 되며 진공 단열 패널의 단열성능의 수명을 길게 할 수가 있다.Furthermore, as described above, the filling bodies 2 are formed by pressurizing the powder bodies and combining them, so that the gap between the powder bodies becomes smaller, so that gas leakage occurs in the outer shell 1 and the pressure inside the outer shell 1 increases. In addition, the change in thermal conductivity is small, and the lifetime of the thermal insulation performance of the vacuum insulation panel can be extended.

또한 전술한 실시예에서는 충진체(2) 전체를 규산칼슘판상의 결정 분말로 된 분말체로 형성하였으나 이것에 한정되지 않으며 예를 들면 알루미나 분말 또는 실리카 분말을 기제(基劑)로 하고 이 기제에 규산 칼슘판상의 결정 분말을 5중량% 이상 함유시켜서 된 분말체로 충진체를 구성해도 좋으며 이 경우에도 전술한 실시예와 같은 작용효과를 얻을 수가 있다.In addition, in the above-mentioned embodiment, although the whole filling body 2 was formed into the powder of the calcium silicate plate crystal powder, it is not limited to this, For example, alumina powder or a silica powder is used as a base, and a silicate is used for this base. The filler may be composed of a powder containing 5 wt% or more of calcium plate-like crystal powder, and in this case, the same effects as in the above-described embodiments can be obtained.

본 발명은 이상의 설명에서 명백한 바와 같이 외곽 내부에 수납되는 충진체인 분말체를 가압해서 서로 결합시킴으로써 형성된 다공질 성형체로 구성하였으므로 외곽의 내부에서 공기를 배기시킬 때에 배기 소요시간을 단축시킬 수 있는 동시에 충진체의 분말체가 외부로 새는 것을 방지할 수가 있으며, 더욱이 취급의 작업성을 향상시킬 수 있으며, 또한 기기의 수명을 길게할 수 있는 등 여러 가지 우수한 효과를 이룰 수 있다.As apparent from the above description, the present invention is made of a porous molded body formed by pressurizing the powders, which are filled in the outer body, and bonding them to each other, thereby reducing the exhaust time required when exhausting the air from the outer part. It is possible to prevent the powder from leaking to the outside, to improve the workability of handling, and also to achieve various excellent effects, such as to prolong the life of the device.
