Description

직냉식 냉장고{ A direct cooling-typed refrigerator }Direct Cooling Refrigerator {A direct cooling-typed refrigerator}

본 고안은 냉장고에 관한 것으로, 특히 업소용으로 주로 사용되는 직냉식 냉장고에 관한 것이다.The present invention relates to a refrigerator, and in particular to a direct-cooling refrigerator mainly used for business.

일반적으로, 냉장고는 증발기에 의해 냉각된 공기를 순환시키는 간냉식과 냉매가 흐르는 냉매관이 증발기 역할을 하도록 함으로써 별도로 증발기가 필요없는 직냉식이 있다.In general, a refrigerator has direct cooling that circulates air cooled by an evaporator and a refrigerant tube through which a refrigerant flows to serve as an evaporator.

이와 같은 직냉식은 냉동실과 냉장고가 격실로 분리되어 있으나 일련의 연속된 냉매관을 공통으로 사용하고 냉장실 보다 냉동실에 냉매관을 더 많이 설치함으로써 냉동실과 냉장실의 온도차를 발생시키도록 되어 있다.In this type of direct cooling, the freezer compartment and the refrigerator are separated into compartments, but a series of continuous refrigerant tubes are commonly used, and more refrigerant tubes are installed in the freezer compartment than the freezer compartment to generate a temperature difference between the freezer compartment and the refrigerator compartment.

따라서, 초기의 냉매관 설치에 따라 온도차가 정형화되므로 냉동실과 냉장실의 온도를 독립적으로 조절할 수 없는 문제점이 있었다.Therefore, since the temperature difference is normalized according to the initial refrigerant pipe installation, there is a problem that the temperature of the freezing compartment and the refrigerating compartment cannot be independently controlled.

특히, 종래의 직냉식 냉장고는 업소용으로 사용하는 경우가 많아 가정용에 비해 비교적 규모가 크므로 운반과 설치가 용이하지 않고, 냉동실과 냉장실이 분리되어 있으므로 보관하고자 하는 물건의 양에 따라 공간을 효율적으로 사용할 수 없는 문제점이 있었다.In particular, conventional direct-cooling refrigerators are often used for businesses, and are relatively large in size compared to homes, so they are not easy to carry and install, and the freezer compartment and the refrigerator compartment are separated so that the space can be used efficiently according to the amount of objects to be stored. There was a problem that could not be.

이에 본 고안은 상기한 바의 제반 문제점들을 해소하기 위해 안출된 것으로, 냉동실과 냉장실로 유입되는 냉매관을 각각 독립적으로 개폐하여 냉동실과 냉장실의 온도를 독립적으로 제어할 수 있는 직냉식 냉장고를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, to provide a direct-cooling refrigerator that can independently control the temperature of the freezer compartment and the freezer compartment by opening and closing the refrigerant pipe flowing into the freezer compartment and the refrigerator compartment independently. There is a purpose.

상기한 바의 목적을 달성하기 위한 본 고안은, 상부격실과, 하부격실, 상기상부격실과 하부격실로 냉매를 순환시키는 냉매관과, 상기 냉매관의 냉매를 압축시키는 압축기, 상기 압축기를 통과한 냉매를 응축시켜 열을 방출하는 응축기, 상기 상부격실로 유입되는 냉매관을 개폐하는 제1개폐밸브, 상기 하부격실로 유입되는 냉매관을 개폐하는 제2개폐밸브, 상기 상부격실 내부의 온도를 감지하여 상기 제1개폐밸브를 개폐하는 제1온도조절기, 상기 하부격실 내부의 온도를 감지하여 상기 제2개폐밸브를 개폐하는 제2온도조절기로 구성되어 있다.The present invention for achieving the above object, the upper compartment, the lower compartment, a refrigerant pipe for circulating the refrigerant to the upper compartment and the lower compartment, a compressor for compressing the refrigerant of the refrigerant pipe, the compressor passed through A condenser for condensing refrigerant to release heat, a first opening and closing valve for opening and closing a refrigerant pipe flowing into the upper compartment, a second opening and closing valve for opening and closing a refrigerant pipe flowing into the lower compartment, sensing a temperature inside the upper compartment And a first temperature controller for opening and closing the first opening and closing valve, and a second temperature controller for opening and closing the second opening and closing valve by sensing a temperature inside the lower compartment.

이하 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 고안에 따른 직냉식 냉장고는, 상부격실(11)과, 하부격실(12), 상기 상부격실(11)과 하부격실(12)로 냉매를 순환시키는 냉매관(20)과, 상기 냉매관(20)의 냉매를 압축시키는 압축기(30), 상기 압축기(30)를 통과한 냉매를 응축시켜 열을 방출하는 응축기(40), 상기 상부격실(11)로 유입되는 냉매관(20)을 개폐하는 제1개폐밸브(51), 상기 하부격실(12)로 유입되는 냉매관(20)을 개폐하는 제2개폐밸브(52), 상기 상부격실(11) 내부의 온도를 감지하여 상기 제1개폐밸브(51)를 개폐하는 제1온도조절기(61), 상기 하부격실(12) 내부의 온도를 감지하여 상기 제2개폐밸브(52)를 개폐하는 제2온도조절기(62)를 포함한다.The direct-cooling refrigerator according to the present invention, the upper compartment 11, the lower compartment 12, the refrigerant pipe 20 for circulating the refrigerant to the upper compartment 11 and the lower compartment 12, and the refrigerant tube 20 Compressor 30 for compressing the refrigerant of the), the condenser 40 for condensing the refrigerant passing through the compressor 30 to release heat, the agent for opening and closing the refrigerant pipe 20 introduced into the upper compartment 11 The first opening and closing valve 51, the second opening and closing valve 52 for opening and closing the refrigerant pipe 20 introduced into the lower compartment 12, the temperature inside the upper compartment 11 by detecting the first opening and closing valve ( And a first temperature controller 61 for opening and closing 51 and a second temperature controller 62 for opening and closing the second opening / closing valve 52 by sensing a temperature inside the lower compartment 12.

상기 상부격실(11)과 하부격실(12)은 서로 분리되고, 그 상부격실(11)과 하부격실(12)의 내부로 냉매관(20)이 관통하여 설치되어 있다.The upper compartment 11 and the lower compartment 12 are separated from each other, and the refrigerant pipe 20 penetrates into the upper compartment 11 and the lower compartment 12.

상기 상부격실(11)의 내부에 응축기(40)를 통과한 냉매가 유입되는 제1냉매관(22)과, 상기 제1냉매관(22)을 통과한 냉매가 유입되는 제2냉매관(21)으로 구성되어 있다.The first refrigerant pipe 22 through which the refrigerant passing through the condenser 40 flows into the upper compartment 11, and the second refrigerant pipe 21 through which the refrigerant passing through the first refrigerant pipe 22 flows in. )

상기 하부격실(12)의 내부에 상기 제1냉매관(22)에서 토출되는 냉매를 통과시키는 제3냉매관(23)이 구비되어 있다.A third refrigerant pipe 23 through which the refrigerant discharged from the first refrigerant pipe 22 passes is provided in the lower compartment 12.

상기 제1냉매관(22)과 제2냉매관(21)은 제1개폐밸브(51)에 의해 서로 연통가능하게 되고, 상기 제1냉매관(22)과 제3냉매관(23)은 제2개폐밸브(52)에 의해 서로 연통가능하게 된다.The first refrigerant pipe 22 and the second refrigerant pipe 21 can be communicated with each other by the first opening and closing valve 51, the first refrigerant pipe 22 and the third refrigerant pipe 23 is The two open / close valves 52 enable communication with each other.

즉, 제1개폐밸브(51)를 닫고 제2개폐밸브(52)를 개방하게 되면 제1냉매관(22)과 제2냉매관(21)은 연결이 차단되고 제1냉매관(22)의 냉매가 제3냉매관(23)으로 순환하게 된다.That is, when the first opening / closing valve 51 is closed and the second opening / closing valve 52 is opened, the connection between the first refrigerant pipe 22 and the second refrigerant pipe 21 is blocked and the first refrigerant pipe 22 is closed. The refrigerant is circulated to the third refrigerant pipe 23.

상기의 경우 제1냉매관(22)과 제3냉매관(23)으로 냉매가 순환하게 되므로 상부격실(11)과 하부격실(12)의 내부 온도가 내부 공간 부피에 따라 달라지게 되고 상부격실(11)과 하부격실(12)의 내부 부피가 동일하다면 상부격실(11)과 하부격실(12)은 동일한 온도를 나타내게 된다.In this case, since the refrigerant is circulated to the first refrigerant pipe 22 and the third refrigerant pipe 23, the internal temperature of the upper compartment 11 and the lower compartment 12 is changed according to the internal space volume, and the upper compartment ( 11) and the lower compartment 12 has the same internal volume, the upper compartment 11 and the lower compartment 12 will show the same temperature.

따라서, 설정온도에 따라 상기 상부격실(11)과 하부격실(12) 모두 냉동실이나 냉장실로 동일하게 사용될 수 있게 되고, 도 4에 도시된 바와 같이 1개의 상부격실(11)과 1개의 하부격실(12)을 한조로 하는 2쌍의 격실(10)을 연속적으로 결합하여 사용할 수 있게 된다.Therefore, both the upper compartment 11 and the lower compartment 12 may be used as the freezing compartment or the refrigerating compartment according to a set temperature, and as shown in FIG. 4, one upper compartment 11 and one lower compartment ( It is possible to combine two pairs of compartments (10) in a row in succession.

즉, 상부격실(11)과 하부격실(12) 모두 냉동실이나 냉장실로 사용가능하므로 운반과 설치가 용이하게 격실을 소형으로 제작하여 설치장소에 다수개를 설치함으로써 필요에 따라 전체를 냉장실이나 냉동실로 사용할 수 있게 되고, 그로 인해 냉장실과 냉동실을 별도로 구비하여 공간을 많이 차지하는 것을 방지할 수 있게 된다.That is, since both the upper compartment 11 and the lower compartment 12 can be used as a freezing compartment or a refrigerating compartment, the compartments can be made small in size for easy transport and installation, and a plurality of the compartments are installed at the installation place. It is possible to use, and thus it is possible to prevent the use of a lot of space by having a refrigerator compartment and a freezer compartment separately.

상기 상부격실(11)과 다른 상부격실(11)의 상부가 결합볼트(71) 결합되며, 하부격실(12)과 다른 하부격실(12)의 하부에 각각 지지볼트(72)가 구비되고, 그 1쌍의 지지볼트(72)를 결합부재(73)가 물어 잡아 2쌍의 격실(10)을 인접하게 결합할 수 있게 된다.The upper compartment 11 and the upper portion of the other upper compartment 11 is coupled to the coupling bolt 71, the support bolt 72 is provided at the lower portion of the lower compartment 12 and the other lower compartment 12, respectively, The pair of support bolts 72 are caught by the coupling member 73 so that the two pairs of compartments 10 can be adjacently coupled.

또한, 상기 제2개폐밸브(52)를 닫고 상기 제1개폐밸브(51)를 개방하게 되면 제1냉매관(22)의 냉매가 제2냉매관(21)으로 순환하게 되고, 제3냉매관(23)으로의 순환이 차단된다.In addition, when the second opening / closing valve 52 is closed and the first opening / closing valve 51 is opened, the refrigerant of the first refrigerant pipe 22 is circulated to the second refrigerant pipe 21, and the third refrigerant pipe The circulation to 23 is cut off.

따라서, 상기 제3냉매관(23)이 통과하는 하부격실(12)에는 냉각이 정지되어 온도가 점차적으로 상승하게 되고, 상부격실(11)만 제1냉매관(22)과 제2냉매관(21)에 의해 계속해서 냉각가능하게 됨으로써 상부격실(11)은 냉장과 냉동이 모두 가능하게 된다.Therefore, cooling is stopped in the lower compartment 12 through which the third refrigerant pipe 23 passes, and the temperature is gradually increased. Only the upper compartment 11 has the first refrigerant pipe 22 and the second refrigerant pipe ( Continued cooling by 21) enables the upper compartment 11 to be both refrigerated and frozen.

여기서, 상기 제2냉매관(21)은 제1냉매관(22)의 냉매가 제3냉매관(23)으로 순환하다가 제2개폐밸브(52)의 차단으로 인해 발생하는 압력변화를 상쇄시키는 역할을 하는 것으로, 제3냉매관(23)의 길이와 동일하게 하여 냉매의 이동거리를 충분히 확보함으로써 압력변화를 줄일 수 있게 된다.Here, the second refrigerant pipe 21 serves to cancel the pressure change caused by the refrigerant in the first refrigerant pipe 22 circulates into the third refrigerant pipe 23 and the second opening / closing valve 52 is blocked. By making it equal to the length of the third refrigerant pipe 23, the pressure change can be reduced by sufficiently securing the moving distance of the refrigerant.

또한, 도 5에 도시된 바와 같이, 상기 제2냉매관(21)을 다른 격실(10)로 우회시켜 상부격실(11)과 함께 냉각되도록 하는 것도 가능하다.In addition, as shown in FIG. 5, the second refrigerant pipe 21 may be diverted to another compartment 10 to be cooled together with the upper compartment 11.

상기 제1온도조절기(61)는 상기 상부격실(11)의 온도를 설정하고, 상기 제2온도조절기(62)는 하부격실(12)의 온도를 설정하며, 상기 제2개폐밸브(52)를 개폐시키는 전기신호를 인가하고, 제2온도조절기(62)는 상기 제1개폐밸브(51)와 제2개폐밸브(52)를 선택적으로 개폐시키는 전기신호를 인가할 수 있게 된다.The first temperature controller 61 sets the temperature of the upper compartment 11, the second temperature controller 62 sets the temperature of the lower compartment 12, and opens the second opening / closing valve 52. An electric signal for opening and closing is applied, and the second temperature controller 62 is capable of applying an electric signal for selectively opening and closing the first open / close valve 51 and the second open / close valve 52.

상기 타이머(T)는 제1온도조절기(61)가 제2개폐밸브(52)를 작동시키는 전원을 인가할 때 압축기(30)의 작동을 지연시켜 모터의 고장을 방지하는 역할을 한다.The timer T serves to prevent the failure of the motor by delaying the operation of the compressor 30 when the first temperature controller 61 applies power for operating the second opening / closing valve 52.

즉, 상기 압축기(30)가 작동하다가 정지된 후 상기 제1온도조절기(61)와 제2온도조절기(62)로 다시 전원을 인가하더라도 일정시간이 경과하기 전에는 작동하지 않도록 함으로써 모터의 토크에 의한 고장을 방지할 수 있게 된다.That is, even if the compressor 30 is operated and then stopped, even if power is again supplied to the first temperature controller 61 and the second temperature controller 62, the compressor 30 is not operated until a predetermined time has elapsed. The failure can be prevented.

상기 제1온도조절기(61)와 제2온도조절기(62)는 독립적으로 작동하여 압축기(30)를 작동시키게 되므로, 제1온도조절기(61)나 제2온도조절기(62) 중 어느 하나의 설정온도에 의해 압축기(30)가 정지하였다가 다른 온도조절기의 작동에 의해 압축기(30)로 즉시 전원이 인가되더라도 수분의 시간동안 전원공급을 지연시켜 압축기(30)를 보호하게 되는 것이다.Since the first temperature controller 61 and the second temperature controller 62 operates independently to operate the compressor 30, one of the first temperature controller 61 and the second temperature controller 62 is set. Although the compressor 30 is stopped by the temperature and the power is immediately supplied to the compressor 30 by the operation of another temperature controller, the compressor 30 is protected by delaying the power supply for a few minutes.

이상에서 설명한 바와 같이 본 고안에 따른 직냉식 냉장고에 의하면, 냉동실과 냉장실로 유입되는 냉매관을 각각 독립적으로 개폐하여 냉동실과 냉장실의 온도를 독립적으로 제어할 수 있고, 좁은 공간에도 소형으로 설치가 가능하며, 운반과 설치가 용이하게 할 수 있는 효과가 있다.As described above, according to the direct-cooling refrigerator according to the present invention, the refrigerant pipes flowing into the freezing compartment and the refrigerating compartment are independently opened and closed to control the temperature of the freezing compartment and the refrigerating compartment independently, and can be installed in a small space. This has the effect of facilitating transport and installation.
