본 발명은 김치냉장고의 제어 장치에 관한 것으로서, 보다 상세하게는 냉각장치의 드라이어가 수직으로 장착된 김치냉장고에서 압축기를 오프시킨 후 스텝밸브를 설정시간 동안 개방시켜 냉매가 압력차로 인해 저장실에 자연 공급되도록 함으로써 무전력 냉각효과를 올릴 수 있도록 하는 김치냉장고의 제어 장치에 관한 것이다. More particularly, the present invention relates to a control device for a kimchi refrigerator, and more particularly, to a kimchi refrigerator in which a dryer of a cooling device is vertically mounted, a compressor is turned off in a kimchi refrigerator, So that the powerless cooling effect can be enhanced.

일반적으로, 김치냉장고는 일반 냉장고의 원리를 채택하고 있으나, 일반 냉장고와 달리 김치만을 전용으로 숙성하고 신선하게 보관할 수 있도록 하는 기능을 수행한다. 즉 김치냉장고는 계절의 변화 및 사용자의 기호에 따라 김치를 적당히 숙성시킨 다음, 적정온도로 유지하여 잘 익은 김치의 맛을 오랫동안 보존할 수 있도록 구성되어 있다. Generally, the Kimchi refrigerator adopts the principle of a general refrigerator, but unlike an ordinary refrigerator, the kimchi refrigerator performs only a function of allowing the kimchi to be matured and stored freshly. That is, the Kimchi refrigerator is configured to keep the taste of ripe kimchi for a long time by moderately aging the kimchi according to seasonal changes and user's preference, and then keeping it at the proper temperature.

이와 같은 김치냉장고는 냉각장치와 가열장치를 구비하고 있어 사용자가 시스템을 발효 또는 숙성모드로 선택하면 가열장치가 구동되어 저장용기에 담아진 김치를 발효시킨 다음, 냉각장치가 구동되어 냉장고의 내부온도를 일정하게 유지시킴으로써, 김치의 맛과 신선도를 장기간 보존하는 것이 가능하게 된다. 이를 위해 냉매를 사용하여 김치의 신선도를 보존하게 되는데, 보통 냉각 사이클은 냉매를 고온, 고압의 가스 상태로 만드는 압축기와, 이 압축기에서 보내진 고온, 고압의 냉매를 송풍팬에 의해 강제 냉각하여 액화시키는 응축기와, 액화된 냉매를 팽창시키는 팽창밸브와, 팽창밸브를 통과하면서 기화되는 과정에서 주변의 공기가 갖고 있는 열을 흡수하여 차갑게 냉각시키는 증발기를 통하여 이루어지게 된다.The Kimchi refrigerator includes a cooling device and a heating device. When the user selects the fermentation or aging mode, the user drives the heating device to ferment the kimchi stored in the storage container, and then the cooling device is driven to cool the inside temperature of the refrigerator The taste and freshness of the kimchi can be preserved for a long period of time. In order to accomplish this, the freshness of the kimchi is preserved by using the refrigerant. Usually, the cooling cycle includes a compressor for making the refrigerant into a high-temperature and high-pressure gaseous state and a high-temperature and high-pressure refrigerant sent from the compressor, A condenser, an expansion valve for expanding the liquefied refrigerant, and an evaporator for cooling the refrigerant by absorbing the heat of surrounding air while being vaporized while passing through the expansion valve.

In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

도 1은 본 발명의 일 실시예에 따른 김치냉장고의 제어 장치를 나타낸 블록구성도이다. 1 is a block diagram showing a controller of a Kimchi refrigerator according to an embodiment of the present invention.

도 1에 도시된 바와 같이 본 발명의 일 실시예에 따른 김치냉장고의 제어 장치는 압축기(10), 스텝밸브(40) 및 제어부(60)를 포함한다. As shown in FIG. 1, the controller of the Kimchi refrigerator according to the embodiment of the present invention includes a compressor 10, a step valve 40, and a controller 60.

압축기(10)는 제 1내지 제 3저장실(R1, R2, R3)에 설치된 제 1내지 제 3증발기(71, 72, 73)로부터 유입된 냉매를 고온 고압으로 압축시킨다. The compressor 10 compresses the refrigerant introduced from the first to third evaporators 71, 72, 73 installed in the first to third storage rooms R1, R2, R3 to high temperature and high pressure.

제 1내지 제 3저장실(R1, R2, R3)은 제 1내지 제 3저장실(71,72, 73)을 구비할 수 있으며, 제 1저장실(R1)은 제 1증발기(71)와 송풍기(80)를 구비하여 송풍기(80)에 의해 냉기를 순환시키는 간냉식 저장실이고, 제 2저장실(R2)은 제 2증발기(72)가 구비되고, 제 3저장실(R3)은 제 3증발기(73)가 구비된 직냉식 저장실이다. The first to third storage rooms R1, R2 and R3 may have first to third storage rooms 71, 72 and 73. The first storage room R1 is connected to the first evaporator 71 and the blower 80 The second storage room R2 is provided with a second evaporator 72 and the third storage room R3 is provided with a third evaporator 73. The second evaporator 72 is provided in the second storage room R2, Cooled storage compartment.

압축기(10)에서 압축된 냉매는 응축기(20)를 지나면서 함유된 열을 방출하면서 액화되고, 액화된 냉매는 드라이어(30)를 통과하면서 냉매에 함유된 수분이나 이물질이 걸러진다. The refrigerant compressed in the compressor (10) is liquefied while releasing heat contained in the refrigerant passing through the condenser (20), and the liquefied refrigerant passes through the dryer (30) and water or foreign matter contained in the refrigerant is filtered.

스텝밸브(40)는 순차적으로 개폐되면서 드라이어(30)를 통과한 냉매를 제 1내지 제 3증발기(71, 72, 73)로 배출되도록 한다. The step valve 40 is sequentially opened and closed so that the refrigerant that has passed through the dryer 30 is discharged to the first to third evaporators 71, 72, and 73.

이때 드라이어(30)는 응축기(20)와 스텝밸브(40) 사이에 수직으로 설치되어 냉매가 드라이어(30)의 하부에 고이게 되도록 함으로써 압축기(10)가 정지되어 냉매를 밀어내지 않더라도 하부에 설치된 스텝밸브(40)가 개방될 경우 중력과 미세한 압력차에 의해 냉매가 증발기(70)로 자연 공급되도록 한다. At this time, the dryer 30 is vertically installed between the condenser 20 and the step valve 40 so that the refrigerant is concentrated on the lower portion of the dryer 30, so that the compressor 10 is stopped, When the valve 40 is opened, the refrigerant is naturally supplied to the evaporator 70 by the gravity and the minute pressure difference.

스텝밸브(40)에서 배출된 냉매는 감압장치(50)를 통과하여 저압상태로 바뀐 뒤 제 1내지 제 3증발기(71, 72, 73)에 공급됨으로써, 제 1내지 제 3증발기(71, 72, 73)에서는 저압상태로 바뀐 냉매가 증발되면서 주변의 열을 흡수하여 제 1내지 제 3저장실(R1, R2, R3)을 냉각시키게 된다. The refrigerant discharged from the step valve 40 is supplied to the first to third evaporators 71, 72 and 73 after passing through the decompressor 50 to be in a low pressure state so that the refrigerant discharged from the first to third evaporators 71 and 72 And 73, the refrigerant changed into a low-pressure state is evaporated and absorbs the surrounding heat to cool the first to third storage rooms R1, R2, and R3.

제어부(60)는 제 1내지 제 3저장실(R1, R2, R3)의 고내온도와 설정온도를 기반으로 압축기(10)의 구동조건을 판단하여 압축기(10)와 스텝밸브(40)를 구동시켜 제 1내지 제 3증발기(71, 72, 73) 중 해당되는 증발기(70)에 냉매를 유입시켜 각 저장실(100)을 냉각시킨다. The control unit 60 determines the driving conditions of the compressor 10 based on the internal temperature and the set temperature of the first to third storage rooms R1, R2 and R3 and drives the compressor 10 and the step valve 40 Refrigerant is introduced into the corresponding evaporator 70 of the first to third evaporators 71, 72, and 73 to cool the respective storage compartments 100.

또한, 제어부(60)는 압축기(10)의 정지 조건에 따라 압축기(10)를 정지시킨 후 스텝밸브(40)를 설정시간 동안 순차적으로 개폐시켜 드라이어(30)에 고여 있는 냉매가 중력과 압력차로 인해 제 1내지 제 3증발기(71, 72, 73)에 자연 유입될 수 있도록 한다. The control unit 60 stops the compressor 10 according to the stop condition of the compressor 10 and sequentially opens and closes the step valve 40 for a preset time period so that the refrigerant remaining in the dryer 30 is discharged by the gravity So that they can flow into the first to third evaporators 71, 72 and 73 naturally.

이와 같이 압축기(10)를 정지시킨 후 스텝밸브(40)를 순차적으로 개폐시킬 때 제 1내지 제 3증발기(71, 72, 73) 중 직냉식 저장실인 제 2저장실(R2)의 제 2증발기(72)와 제 3저장실(R3)의 제 3증발기(73)에만 냉매가 유입될 수 있도록 선택적으로 제어할 수 있다. When the step valve 40 is sequentially opened and closed after the compressor 10 is stopped, the second evaporator 72 of the second storage chamber R2, which is a freely cooled storage chamber among the first to third evaporators 71, 72, ) And the third evaporator (73) of the third storage chamber (R3).

이때 설정시간은 김치냉장고의 용량에 따라 최적화할 수 있으며 평압이 이루어지는 시간으로 설정할 수 있다. At this time, the set time can be optimized according to the capacity of the Kimchi refrigerator and can be set as the time when the pneumatic pressure is performed.

이와 같은 김치냉장고의 제어 장치에 대한 동작을 도 2에 도시된 발명의 일 실시예에 따른 김치냉장고의 제어 장치에 따른 동작을 설명하기 위한 흐름도를 참조하여 설명하면 다음과 같다. The operation of the controller of the Kimchi refrigerator will now be described with reference to a flowchart illustrating an operation of the controller of the Kimchi refrigerator according to the embodiment of the present invention shown in FIG.

먼저, 제어부(60)가 제 1내지 제 3저장실(R1, R2, R3)의 고내온도와 설정온도를 비교하여 압축기(10)의 구동 조건을 판단한다(S10). First, the controller 60 compares the internal temperature of the first to third storage chambers R1, R2, R3 with the set temperature to determine the driving condition of the compressor 10 (S10).

S10 단계에서 압축기(10)의 구동 조건을 판단하여 압축기(10)의 구동 조건을 만족할 경우, 제어부(60)는 압축기(10)를 구동시킨다(S20). 그리고, 제어부(60)는 고내온도에 따라 스텝밸브(40)를 순차적으로 개폐 구동하여 냉각시키고자 하는 저장실(100)에 냉매가 배출될 수 있도록 한다(S30). If the driving condition of the compressor 10 is satisfied in step S10, the controller 60 drives the compressor 10 (S20). Then, the controller 60 sequentially drives the step valve 40 to open and close the storage compartment 100 according to the internal temperature, thereby discharging the refrigerant to the storage compartment 100 to be cooled (S30).

이와 같이 제어부(60)는 압축기(10)의 구동 조건에 따라 압축기(10)와 스텝밸브(40)를 구동시켜 냉각이 필요한 저장실(100)의 증발기(70)에 냉매가 배출될 수 있도록 한다. The controller 60 drives the compressor 10 and the step valve 40 according to the driving conditions of the compressor 10 so that the refrigerant can be discharged to the evaporator 70 of the storage compartment 100 requiring cooling.

반면, S10 단계에서 압축기(10)의 구동 조건을 판단하여 압축기(10)의 구동 조건을 만족하지 않는 경우, 제어부(60)는 구동 중인 압축기(10)의 구동을 정지시킨다(S40). 또한, 정지된 상태인 압축기는 정지상태를 유지시킨다. On the other hand, if the driving condition of the compressor 10 is not satisfied in step S10, the controller 60 stops driving the compressor 10 in operation (S40). Further, the compressor in the stopped state maintains the stopped state.

S40 단계에서 압축기(10)의 구동을 정지시킨 후 스텝밸브(40)를 설정시간 동안 순차적으로 개폐시켜 드라이어(30)에 고여 있는 냉매가 중력과 압력차로 인해 제 1내지 제 3증발기(71, 72, 73)에 자연 유입될 수 있도록 한다(S50). The driving of the compressor 10 is stopped in step S40 and the step valve 40 is sequentially opened and closed for a preset time period so that the refrigerant flowing in the dryer 30 flows into the first to third evaporators 71 and 72 , And 73 (S50).

여기서 스텝밸브(40)를 순차적으로 개폐시킬 때 제 1내지 제 3증발기(71, 72, 73) 중 직냉식 저장실인 제 2저장실(R2)의 제 2증발기(72)와 제 3저장실(R3)의 제 3증발기(73)에만 냉매가 유입될 수 있도록 선택적으로 제어할 수 있다. When the step valve 40 is sequentially opened and closed, the second evaporator 72 of the second storage chamber R2, which is a freely-cooled storage chamber among the first to third evaporators 71, 72 and 73, It is possible to selectively control the refrigerant to flow into the third evaporator 73 only.

S50 단계에서 설정시간 동안 스텝밸브(40)를 순차적으로 개폐시킨 후 스텝밸브(40)를 폐쇄시킨다(S60). In step S50, the step valve 40 is sequentially opened and closed for a set time, and then the step valve 40 is closed (S60).

상술한 바와 같이, 본 발명의 실시예에 의한 김치냉장고의 제어 장치에 따르면, 냉각장치의 드라이어가 수직으로 장착된 김치냉장고에서 압축기를 오프시킨 후 스텝밸브를 설정시간 동안 개방시켜 냉매가 압력차로 인해 저장실에 자연 공급되도록 함으로써 무전력으로 소비전력을 절감하면서 냉각효과를 올릴 수 있도록 한다. As described above, according to the control apparatus of the Kimchi refrigerator according to the embodiment of the present invention, after the compressor is turned off in the kimchi refrigerator in which the dryer of the cooling apparatus is vertically installed, the step valve is opened for the set time, By allowing the power to be supplied to the storage room naturally, it is possible to increase the cooling effect while reducing power consumption by power-free.
