이 때, 상기 외기유입차단수단은, 도 2에 도시된 바와 같이, 상기 배수관(5)의 상부에 구비되어 배수관의 상부를 개폐시키는 제1 밸브(51)와; 상기 배수관에 구비되되 제1 밸브와 배수관의 끝단부 사이에 구비되어 제1 밸브를 통해 유입된 제상수를 저장하는 제상수저장챔버(52)와; 상기 제상수저장챔버와 상기 배수관의 끝단 사이에 구비되어 배수관의 하부를 개폐시키는 제2 밸브(53)와; 평상시, 상기 제상수저장챔버(52)로 제상수가 이동되도록 제1 밸브(51)를 열어주고 외부공기가 진공챔버(30)내로 유입되지 못하도록 상기 제2 밸브(53)를 닫아주며, 상기 제상수 배출시, 상기 제상수저장챔버내의 제상수가 외부로 배출되도록 상기 제2 밸브(53)를열어주고 외부공기가 진공챔버(30)내로 유입되지 못하도록 상기 제1 밸브(51)를 닫아주는 마이콤(도시생략)이 포함되어 이루어진다.At this time, the external air inlet blocking means, as shown in Figure 2, the first valve 51 which is provided on the upper portion of the drain pipe 5 to open and close the upper portion of the drain pipe; A defrost water storage chamber 52 provided in the drain pipe and provided between the first valve and the end of the drain pipe to store defrost water introduced through the first valve; A second valve 53 provided between the defrost water storage chamber and an end of the drain pipe to open and close a lower portion of the drain pipe; Normally, the first valve 51 is opened to move the defrost water to the defrost water storage chamber 52 and the second valve 53 is closed to prevent external air from entering the vacuum chamber 30. When the water is discharged, the microcomputer that opens the second valve 53 to discharge the defrost water in the defrost water storage chamber to the outside and closes the first valve 51 so that external air does not flow into the vacuum chamber 30 (Not shown) is included.

상기와 같이 이루어진 본 발명은 다음과 같은 동작을 수행한다.The present invention made as described above performs the following operation.

먼저, 진공챔버(30)내를 진공상태로 유지하기 위해 진공펌프(40)가 가동되어 진공챔버내의 공기를 배기시키게 된다.First, in order to maintain the inside of the vacuum chamber 30 in a vacuum state, the vacuum pump 40 is operated to exhaust the air in the vacuum chamber.

이 때, 고내 전체가 진공챔버(30)로 이루어진 경우, 외부공기가 배수관(5)을 통해 유입되게 되는데, 이를 막기 위해 외기유입차단수단은 다음과 같은 동작을 수행한다.At this time, when the whole inside is made of a vacuum chamber 30, the outside air is introduced through the drain pipe (5), the external air inlet blocking means performs the following operations to prevent this.

첫째, 평상시, 도 3a에 도시된 바와 같이 마이콤(도시생략)에 의해 제1 밸브(51)가 열리게 되어 증발기(4)에서 발생되는 제상수가 제상수저장챔버(52)로 이동되고, 이와 동시에, 마이콤에 의해 제2 밸브(53)는 닫힌 상태를 유지하게 되어 외부공기가 진공챔버(30)내로 유입되는 것을 차단시키게 된다.First, normally, as shown in FIG. 3A, the first valve 51 is opened by a microcomputer (not shown), and the defrost water generated in the evaporator 4 is moved to the defrost water storage chamber 52. By the microcomputer, the second valve 53 maintains the closed state to block external air from flowing into the vacuum chamber 30.

둘째, 제상수 배출시, 도 3b에 도시된 바와 같이 마이콤(도시생략)에 의해 제1 밸브(51)가 닫히게 되어 진공챔버(30)내로 외부공기가 유입되는 것을 차단시키게 되고, 이와 동시에, 마이콤에 의해 제2 밸브(53)는 열리게 되어 제상수저장챔버(52)내의 제상수가 외부로 배수되게 된다.Second, when the defrost water is discharged, as shown in FIG. 3B, the first valve 51 is closed by a microcomputer (not shown) to block external air from flowing into the vacuum chamber 30, and at the same time, the microcomputer As a result, the second valve 53 is opened so that the defrost water in the defrost water storage chamber 52 is drained to the outside.

결국, 고내 전체가 진공챔버(30)인 경우 발생될 수 있는 문제인 배수관(5)을 통한 외부공기의 유입을 미연에 차단시킴과 함께, 진공펌프(40)의 가동으로 진공챔버내의 진공도를 일정하게 유지시킴에 따라, 식품을 장기간 보관할 수 있게 된다.As a result, while blocking the inflow of external air through the drain pipe 5, which may be a problem that may occur when the entire chamber is the vacuum chamber 30, the degree of vacuum in the vacuum chamber is constantly maintained by the operation of the vacuum pump 40. By maintaining, the food can be stored for a long time.
