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.

한편, 상기 진공펌프(40)는 상기 배수관(5)에 연통되게 구비될 수 있다On the other hand, the vacuum pump 40 may be provided in communication with the drain pipe (5).

이 때, 본 발명에 따른 진공냉장고는, 도 2에 도시된 바와 같이, 상기 제1 밸브(51)와 제상수저장챔버(52) 사이의 배수관(5)에 일단이 연통되게 구비되고 타단이 상기 진공펌프(40)와 연통되게 구비되는 연결호스(61)와, 상기 연결호스 외주면에 구비되어 증발기(4)가 제상될 때 발생되는 미량의 제상수가 진공펌프 구동시 진공펌프(40)로 유입되지 못하도록 미리 증발시키기 위해 증발기가 제상될 때 같이 가동되는 히터(62)가 더 포함되어 이루어짐이 바람직하다.At this time, the vacuum refrigerator according to the present invention, as shown in Figure 2, one end is provided in communication with the drain pipe 5 between the first valve 51 and the defrost water storage chamber 52 and the other end is A connection hose 61 provided in communication with the vacuum pump 40 and a small amount of defrost water provided when the evaporator 4 is defrosted on the outer circumferential surface of the connection hose flow into the vacuum pump 40 when the vacuum pump is driven. Preferably, the heater 62 is further included when the evaporator is defrosted so as not to evaporate in advance.

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

첫째, 평상시, 도 3a에 도시된 바와 같이 마이콤(도시생략)에 의해 제1 밸브(51)가 열리게 되어 제상시 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. 그리고, 진공챔버내의 진공도에 따라 진공펌프(40)가 가동되어 진공챔버의 공기를 배기시키게 되고, 제상시에는 히터(62)가 같이 가동되어 증발기(4)에서 발생되는 제상수가 진공펌프(40)로 유입되지 못하고 증발하게 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 during defrost is moved to the defrost water storage chamber 52. At the same time, the second valve 53 is kept closed by the microcomputer to block external air from flowing into the vacuum chamber 30. Then, the vacuum pump 40 is operated according to the degree of vacuum in the vacuum chamber to exhaust the air in the vacuum chamber, and during defrosting, the heater 62 is operated together to defrost water generated in the evaporator 4 in the vacuum pump 40. It does not flow into) and evaporates.

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.

그리고, 배수관(5)에 진공펌프(40)를 연통시킴에 따라 진공펌프를 위해 진공챔버(30)에 별도의 유로를 구비시키지 않아도 되므로 구조가 단순해질 수 있다.In addition, as the vacuum pump 40 communicates with the drain pipe 5, the structure may be simplified since it is not necessary to provide a separate flow path in the vacuum chamber 30 for the vacuum pump.

이제까지 본 발명에 대하여 그 바람직한 실시예를 살펴보았으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자는 본 발명의 본질적 기술 범위 내에서 상기 본 발명의 상세한 설명과 다른 형태의 실시예들을 구현할 수 있을 것이다. 여기서 본 발명의 본질적 기술 범위는 특허청구범위에 나타나 있다.So far, the present invention has been described with reference to preferred embodiments, and a person of ordinary skill in the art may implement the above-described detailed description of the present invention and other forms of embodiments within the essential technical scope of the present invention. There will be. Herein the essential technical scope of the present invention is shown in the claims.

이상에서와 같이 본 발명은 식품을 보관하는 진공챔버내의 공기를 배기시켜 고내 전체를 진공상태를 유지시킴에 따라, 공기중의 산소에 의해 냉장 또는 냉동보관중인 식품이 산화되는 것을 미연에 방지할 수 있어 식품을 장기간 보관할 수 있다.As described above, according to the present invention, the air in the vacuum chamber for storing food is evacuated to maintain the entire vacuum state, thereby preventing the food in refrigerated or frozen storage from being oxidized by oxygen in the air. Food can be stored for a long time.

이와 더불어, 진공챔버에 별도의 유로를 구비하여 진공펌프를 연결하지 않고 배수관에 진공펌프를 연결시키므로, 제작비용을 줄일 수 있고, 구조를 단순화시킬 수 있다.In addition, since a separate flow path is provided in the vacuum chamber to connect the vacuum pump to the drain pipe without connecting the vacuum pump, manufacturing cost can be reduced and the structure can be simplified.
