본 고안은 냉장고의 압축기 및 냉각팬 스위치 회로에 관한 것으로서, 특히 통상 운전시에는 하나의 릴레이만 온/오프시켜 압축기 및 냉각팬을 구동시키고, 선택실을 냉동실로 전환시킬때 냉각팬과 구동시키며, 재상복귀시에만 두개의 릴레이를 동시에 온시켜 압축기만 구동시키는 냉장고의 압축기 및 냉각팬 스위치회로에 관한 것이다.The present invention relates to a compressor and a cooling fan switch circuit of a refrigerator, and in particular, only one relay is turned on / off to drive a compressor and a cooling fan during normal operation, and is driven with a cooling fan when the selection chamber is switched to a freezer compartment. The present invention relates to a compressor and a cooling fan switch circuit of a refrigerator, which drives only two compressors by simultaneously turning on two relays at the time of return.
종래에는 제2도에 도시된 바와같이 하나의 릴레이로 압축기와 냉각팬을 동시 동작시키는 방식, 말하자면 논리방식을 채용하였으나, 이러한 방식에서는 냉각기 제상후에 제상히터에 의하여 온도가 상승된 냉각기 주변의 더운공기가 미쳐 냉각되기전에 압축기 운전과 동시에 동작되는 냉각팬에 의하여 냉동실에 유입되므로 냉동실의 냉동효과가 저하될 우려가 있었다. 또한 냉동실과 선택실을 구비한 냉장고에서 냉동실의 온도가 충분히 저하되어 냉동실 온도에 감응하여 작동되는 압축기가 정지된 상태에서 선택실을 냉동실 용도로 전환해야할 경우 냉각팬에 의하여 냉동실의 냉기를 선택실로 강제 대류시켜줌이 바람직하다 압축기와 동시에 냉각팬도 정지하고 있으므로 자연대류에만 의존하게 되어 선택실의 냉동실 전환이 지연되는 결점이 있었다.Conventionally, as shown in FIG. 2, a single relay adopts a method of simultaneously operating a compressor and a cooling fan, that is, a logic method. However, in this method, hot air around a cooler whose temperature is increased by a defrost heater after defrosting the cooler. In addition, since the cooling fan is introduced into the freezing chamber by a cooling fan operated simultaneously with the operation of the compressor before cooling, the freezing effect of the freezing chamber may be lowered. In addition, in the refrigerator having a freezer compartment and a selection chamber, when the temperature of the freezer compartment is sufficiently lowered and the compressor operating in response to the freezer compartment is stopped, the selection chamber needs to be converted to the freezer application, and the cooling fan forces the cold air of the freezer compartment to the selection chamber. Convection is desirable. The cooling fan is also stopped at the same time as the compressor, so it is dependent only on natural convection, which delays the switching of the freezing chamber of the selection chamber.
이와같은 단점을 해결하기 위하여 제3도에 도시된 OR논리방식이 개발되어 상기의 제반문제점들은 해결할수 있었으나 압축기와 냉각팬이 동시에 가동되는 통상 안전시에는 두개의 릴레이(RY1), (RY2)가 동시에 온/오프 되므로 하나의 릴레이를 사용한 방식에 비하여 릴레이에 의한 소비전력이 크고 릴레이의 접점잡음이 커져 예컨대 냉장고의 제어기판과 같은 주변의 전자장치에 오동작을 유발시키는 악영향을 미칠 우려가 있었다.In order to solve the above disadvantages, the OR logic method shown in FIG. 3 was developed to solve the above problems, but in normal safety when the compressor and the cooling fan are simultaneously operated, two relays (RY 1 ) and (RY 2) ) Is on / off at the same time, so the power consumption by the relay is larger and the contact noise of the relay is larger than the method using a single relay, which may adversely affect the peripheral electronic devices such as the control panel of the refrigerator. .
본 고안의 목적은 상기와 같은 종래기술의 제결점들을 해결하기 위하여 두개의 릴레이를 사용하되 통상운전시에는 하나의 릴레이로 압축기와 냉각팬을 동시에 가동시켜 릴레이에 의한 소비전력 및 접점잡음을 감소시킨 냉장고의 압축기 및 냉각팬 스위치 회로를 제공하는데 있다.The purpose of the present invention is to use the two relays to solve the drawbacks of the prior art as described above in normal operation to operate the compressor and the cooling fan at the same time to reduce the power consumption and contact noise by the relay It is to provide a compressor and cooling fan switch circuit of a refrigerator.
이와같은 목적을 달성하기 위하여 본 고안은 공통단자, 온단자 및 오프단자를 각각 갖춘 제1, 제2릴레이를 구비하여 상기 제1릴레이의 공통단자는 교류전원의 일단에 접속시키고, 온단자는 압축기는 일단과 제2릴레이의 오프단자에 공통접속시키고 오프단자는 제2릴레이의 온단자와 접속시키는 한편 제2릴레이의 공통단자에는 타단이 교류전원 및 압축기의 타단에 공통 접속된 냉각팬의 일단을 접속하여서된 것을 특징으로 한다.In order to achieve the above object, the present invention includes first and second relays each having a common terminal, an on terminal, and an off terminal, so that the common terminal of the first relay is connected to one end of an AC power source, and the on terminal is a compressor. Is commonly connected to one end and the off terminal of the second relay, and the off terminal is connected to the on terminal of the second relay, while the other terminal is connected to one end of the cooling fan, the other end of which is commonly connected to the other end of the AC power supply and the compressor. It is characterized by being connected.
이와같이 구성된 본 고안을 첨부된 도면을 참조하여 보다 상세히 설명하기로 한다.The present invention configured as described above will be described in more detail with reference to the accompanying drawings.
제1도는 본 고안의 회로도로써 제1릴레이(RY1)의 공통단자(COM)에는 교류전원(AC)의 일단을 접속하고 제1릴레이(RY1)의 온단자(ON)에는 압축기(COMP) 및 제2릴레이(RY2)의 오프단자(OFF)를 공통 접속하여 제1릴레이(RY1)의 오프단자(OFF)에는 제2릴레이(RY2)의 온단자(ON)를 접속한다. 제2릴레이(RY2)의 공통단자(COM)에는 상기 교류전원(AC)및 압축기(COMP)의 타단에 그타단이 접속된 냉각팬(FAN)의 일단을 접속하여서 된 것이다.1 is a circuit diagram of the present invention. One end of the AC power source AC is connected to the common terminal COM of the first relay RY 1 , and the compressor COMP is connected to the ON terminal ON of the first relay RY 1 . And the off terminal OFF of the second relay RY 2 are commonly connected, and the on terminal ON of the second relay RY 2 is connected to the off terminal OFF of the first relay RY 1 . One end of the cooling fan FAN, the other end of which is connected to the other end of the AC power source AC and the compressor COMP, is connected to the common terminal COM of the second relay RY 2 .
이와같이 구성된 본 고안의 구성에 따른 작용효과를 다음 ＜표·1＞을 참조하여 설명하기로 한다.The operation and effect according to the constitution of the present invention configured as described above will be described with reference to the following <Table 1>.
[표 1]TABLE 1
상기 ＜표 1＞에서와 같이 정지 운전조건에서는 제1, 제2릴레이(RY1), (RY2)가 오프상태로 유지되며, 통상운전시에는 제1릴레이(RY1)만 온상태로 되어 압축기(COMP)가 운전됨과 동시에 제2릴레이(RY2)의 오프상태(COM-OFF)를 통하여 냉각팬(FAN)도 함께 운전되므로 하나의 릴레이를 구동시키는 소비전력만 소모되어 접점잡음이 제3도에 도시된 종래방식에 비하여 반감된다. 선택실을 냉동실로 전환시에는 제2릴레이(RY2)만 온상태(COM-ON)로 되어 교류전원(AC)이 제1릴레이(RY1)의 오프상태(COM-OFF)를 통하여 냉각팬(FAN)이 인가되고 냉각팬(FAN)의 구동으로 냉각기의 냉각된 냉기가 보다 빨리 선택실로 유입되어 선택실을 냉동실로 전환을 앞당길수 있다. 제상복귀시에만 두개의 제1, 2릴레이(RY1), (RY2)를 동시 온상태로 하여 압축기(COMP)에는 제1릴레이(RY1)의 온상태(COM-ON)를 통하여 교류전원(AC)이 공급되어 가동되고 냉각팬(FAN)에는 제2릴레이(RY2)의 온상태(COM-ON)로 교류전원(AC)의 공급이 차단되어 제상히터에 의하여 온도가 상승된 냉각기 주변의 더운 공기가 냉동실로 유입되는 것을 방지할 수 있다.As shown in <Table 1>, the first and second relays RY 1 and RY 2 are kept in the OFF state in the stop operation condition, and only the first relay RY 1 is in the ON state during normal operation. Since the compressor COMP is operated and the cooling fan FAN is also operated through the OFF state COM-OFF of the second relay RY 2 , only the power consumption of driving one relay is consumed, resulting in a third contact noise. Compared to the conventional method shown in FIG. When the selection chamber is switched to the freezer compartment, only the second relay RY 2 is turned on (COM-ON), and the AC power source AC turns the cooling fan through the OFF state (COM-OFF) of the first relay RY 1 . (FAN) is applied and the cooled cold air of the cooler flows into the selection chamber more quickly by the operation of the cooling fan (FAN) to facilitate the conversion of the selection chamber to the freezer compartment. Only the first, second relays (RY 1 ) and (RY 2 ) are turned on at the same time during defrosting and the compressor (COMP) is connected to the AC power supply through the ON state (COM-ON) of the first relay (RY 1 ). (AC) is supplied and operated, and the cooling fan (FAN) is turned off in the ON state (COM-ON) of the second relay (RY 2 ), the supply of AC power (AC) is cut off and the temperature rises by the defrost heater. It is possible to prevent the hot air from entering the freezer.
이와같이 본 고안에서는 종래의 제1도방식, 말하자면 AND논리방식의 상술한 결점과 제2도방식, 말하자면 OR논리방식의 상술한 결점들을 동시에 해결함으로써 냉장고의 소비전력을 감소시키며 냉장고의 자체 전자회로장치 뿐만아니라 주변 전자회로장치에 미치는 릴레이 접점 잡음을 감소시킬 뿐만아니라 냉장고의 신뢰도를 향상시킬수 있는 효과를 얻을 수 있다.As such, the present invention reduces the power consumption of the refrigerator by simultaneously solving the above-described shortcomings of the first FIG. 1 method, that is, the AND logic method, and the above described shortcomings of the second FIG. In addition, it can reduce the relay contact noise on the peripheral electronic circuit device and can improve the reliability of the refrigerator.
