본 고안은 온장 및 냉장기능을 갖는 전자 냉, 온장고에 있어서 외부의 온도가 냉, 온장고의 온도 조절기의 설정온도 보다 낮을시 일어나는 전자 냉, 온장고 기동불능 현상 방지회로에 관한 것이다.The present invention relates to a circuit for preventing electronic cold and warmer start-up phenomenon that occurs when the external temperature is lower than the set temperature of the temperature controller of the cold and warmer in an electronic refrigerator and a refrigerator having a hot and cold function.

종래의 온장 및 냉장기능을 갖는 전자 냉, 온장고는 제2도로 도시된 바와같이 온장시에 선택스위치(1)를 온장스위치 접점(c)(c')에 놓으면 저원은 온장온도 조절기(PTC)와 냉장온도 조절기(2)를 통하여 구동부(5)를 가동시키게 되어 온장기능을 갖게 되며, 또한 고내 온도를 일정범위 이내로 유지하기 위하여 온장온도조절기(PTC)에 전원이 인가되면서 구동부(5)가 기동 및 가열을 하게 되는 것이다.In the conventional electronic cold and cold storage having a function of heating and refrigerating, as shown in FIG. 2, when the selection switch 1 is placed on the heating switch contacts c and c 'at the time of heating, the source is connected to the temperature control controller PTC. The driving unit 5 is operated through the refrigerating temperature controller 2 to have a warming function. In addition, the driving unit 5 starts and operates while power is applied to the heating temperature controller PTC to maintain the internal temperature within a certain range. It will be heated.

그러나 온장 기능시 냉,온장고 주위 온도 및 냉,온장고 자체의 온도가 냉장온도 조절기(2)의 설정온도 보다 더 낮은 온도인 경우에는 냉장온도 조절기(2)의 접점이 "OFF"되어 팬 모터(4) 및 구동부(5)에 전원을 투입하지 못하게 됨으로써 온장고로서 가동을 할 수 없게 되는 문제점이 내재되어 있었다.However, when the temperature of the cold / hothouse temperature and the temperature of the cold / hothouse itself are lower than the set temperature of the refrigerator temperature controller (2) during the heat storage function, the contact point of the refrigerator temperature controller (2) is “OFF” and the fan motor (4 ) And the driving unit 5 cannot be turned on, so that it is impossible to operate as a warmer.

이에 본 고안은 종래의 이러한 문제점을 감안하여 냉, 온장고에 있어서 온장기능시에는, 냉장온도 조절기를 거치지 않고 온장온도 조절기만으로 전원의 투입이 조절될 수 있도록 한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Therefore, the present invention is to allow the input of the power supply only by the temperature control temperature controller without going through the refrigerating temperature controller in the case of the heating function in the cold, warm storage in consideration of the conventional problems, it will be described in detail by the accompanying drawings Is as follows.

입력전원(DC) 양단과 온장온도 조절기(PTC) 및 선택스위치(1)의 접점(b)(b')을 연결하고 선택스위치의 접점(c)(c')과 운전표시등(3), 팬모터(4), 구동부(5)를 병렬 접속하며, 선택스위치의 접점(a)과 접점(c')을 연결하고 접점(a')과 접점(c)을 접속하되 그 사이에 냉장온도 조절기(2)를 접속하여서 된 것이다.Connect both ends of input power (DC), contact temperature controller (PTC) and contact (b) (b ') of selector switch (1), selector switch (c) (c') and operation indicator (3), The fan motor 4 and the drive unit 5 are connected in parallel, and the contact point (a) and the contact point (c ') of the selector switch are connected, and the contact point (a') and the contact point (c) are connected between the refrigerator temperature controllers. It was made by connecting (2).

이와같이 구성된 본 고안의 작용효과를 설명하면 온장 및 냉장기능을 갖는 전자냉, 온장고의 고내 온도를 냉장온도로 유지시키기 위해 선택스위치(1)의 접점(b)(b')이 접점(a)(a')과 접속되게하면 전원(DC)은 온장온도 조절기(PTC)와 접점(b)(b'), (a)(a') 및 냉장온도 조절기(2)를 통하여 흐르게 되며 운전표시등(3)이 점등을 하게되고 팬모터(4)와 구동부(5)가 가동을 하게되어 통상의 냉,온장고와 동일하게 가동할 수 있는 것이다.Referring to the effect of the present invention configured as described above, the contact point (b) (b ') of the selector switch (1) is a contact (a) ( a '), the power supply (DC) flows through the temperature controller (PTC) and the contacts (b) (b'), (a) (a ') and the refrigeration temperature controller (2). 3) is turned on and the fan motor 4 and the drive unit 5 are operated so that they can be operated in the same manner as a normal cold / warmer.

그러므로 냉장실내의 온도가 냉장온도 조절기(2)의 설정온도가 될때까지 냉각시키게 되며, 고내의 온도가 하한 온도가 도달하게 되면 냉장온도 조절기(2)가 오프되어 운전표시등(3)과 팬모터(4) 및 구동부(5)에 전원(DC)도 차단이 되어 운전이 정지되는 것이다.Therefore, it cools down until the temperature in the refrigerator compartment reaches the set temperature of the refrigerator temperature controller (2). When the temperature in the refrigerator reaches the lower limit temperature, the refrigerator temperature controller (2) is turned off to turn on the operation indicator (3) and the fan motor. The power source DC is also cut off to the 4 and the drive unit 5 to stop the operation.

이러한 상태로 일정시간이 경과하면 냉기유출등에 의하여 냉장실내의 온도가 냉장온도 조절기(2)의 상한선 이상으로 상승하게 되며, 이때 냉장온도 조절기(2)가 다시 턴온되어 상기와 같이 운전표시등(3)과 팬모터(4) 및 구동부(5)가 기동을 하게 되어 다시 냉장기능을 발휘하게 되며 이의 반복적인 동작으로 냉장실내의 온도는 설정온도를 유기하게 되는 통상의 냉장고로 사용할 수 있게 되는 것이다.After a certain time has elapsed in such a state, the temperature in the refrigerating chamber rises above the upper limit of the refrigerating temperature controller 2 due to cold air leakage. At this time, the refrigerating temperature controller 2 is turned on again and the operation indicator 3 is ) And the fan motor 4 and the driving unit 5 are started again to exert the refrigerating function. The repetitive operation allows the temperature in the refrigerating chamber to be used as a normal refrigerator to induce a set temperature.

또한 온장고로 사용할 시에는 선택스위치(1)의 접점 (b)(b')이 접점(c)(c')이 접속되도록 하면 전원(DC)은 온장온도 조절기(PTC)의 ON,OFF에 따라 선택스위치(1)의 접점(b)(b')이 접점(c)(c')을 거쳐 운전표시등(3), 팬모터(4)와 구동부(5)에 공급되던 전원의 공급이 단속되어 온장고로서의 기능을 갖게 된다.In case of using as a heating cabinet, if contact (b) (b ') of selector switch (1) is connected to contact (c) and (c'), power supply (DC) is changed according to ON / OFF of temperature controller (PTC). The supply of power supplied to the operation indicator 3, the fan motor 4 and the drive unit 5 is interrupted via the contacts b and b 'of the selector switch 1 via the contacts c and c'. It has a function as a warmer.

즉, 온장고내의 고내온도가 설정온도까지 상승하게 되면 온장온도 조절기(PTC)는 오프되어 운전표시등(3)과 팬모터(4) 및 구동부(5)에 공급되던 전원 또한 차단되어 모든 기능을 일시 정지하게 되는 것이다.In other words, when the temperature inside the refrigerator rises to the set temperature, the temperature controller (PTC) is turned off, and the power supplied to the operation indicator (3) and the fan motor (4) and the driving unit (5) is also cut off to temporarily stop all functions. It will stop.

또한 온장실내의 설정온도가 온장온도 조절기(PTC)의 하한선까지 내려가게 되면 온장온도 조절기(PTC)는 다시 "ON"되어 상기와 같이 반복적인 동작으로 일정한 온도를 유지하게 되는 것이어서, 통상의 냉온장고로 사용할 수 있게 되는 것이다.In addition, when the set temperature in the warm room is lowered to the lower limit of the warm temperature temperature controller (PTC), the warm temperature temperature controller (PTC) is “ON” again to maintain a constant temperature by repeating the operation as described above. It can be used as.

본 고안에서는 특히, 이러한 온장고로서의 가동개시 초기에 주위온도와 자체의 온도가 냉장 온도 조절기(2)의 설정온도 보다 낮은 경우일지라도 전원(DC)은 냉장온도 조절기(2)를 통하지 않고 구동부(5)를 가동시키도록 되어 있어서 온장고를 사용할시에 냉장온도 조절기(2)의 조절상태나 주위온도에 관계없이 가동을 개시할수 있게 된다.In the present invention, in particular, even when the ambient temperature and its own temperature are lower than the set temperature of the refrigerating temperature controller 2 at the initial start of operation as the warmer, the power supply DC does not pass through the refrigerating temperature controller 2 but the driving unit 5. It is possible to start the operation regardless of the controlled state of the refrigerating temperature controller 2 or the ambient temperature when using the warmer.

이상에서와 같이하여 본 고안에서는 온장기능선택시에 냉장온도 조절기(2)의 설정상태나 주위온도 등에 의하여 온장기능개시가 불능하게 됨을 방지할 수 있으므로, 냉,온장고로서의 원활한 기능을 얻을 수 있게 되는 효과가 있다.As described above, the present invention can prevent the starting of the heating function due to the setting state of the refrigerating temperature controller 2 or the ambient temperature at the time of selecting the heating function, so that a smooth function as a cold storage device can be obtained. It works.
