본 고안은 제1도에서와 같이 겸용실(1)과 냉장실(2) 사이의 격벽부(3)를 단열성이 우수하게 한 냉동 냉장 겸용 냉장고에 있어서, 후벽부에 증발기(4)가 설치된 냉장고에 증발기(4)로부터 발생되는 냉기를 팬(5)에 의하여 송출되어 냉장실(2)로 연동되는 증발기(4)와 그릴판(6) 사이에 설치된 냉기통로(7)에 스프링(8)이 탄성력 있게 설치된 절환노브(9)에 의하여 작동되는 절환 샷터(10)를 설치하여 냉장실(2)로 유입되는 통로를 완전히 차단 시킬 수 있도록하여 냉장실(2)를 폐쇄시킬 수 있게 구성되어 있으며, 냉장실(2)을 폐쇄시킬 경우에 발생되는 냉기의 역류를 방지하기 위하여 냉장실 냉기 유출통로(11) 전반부에 개폐판(12)를 설치시킨 것이다.The present invention is a refrigerator freezing combined use refrigerator having excellent thermal insulation of the partition wall portion 3 between the mixing chamber 1 and the refrigerating chamber 2, as shown in FIG. 1, in a refrigerator provided with an evaporator 4 at the rear wall. The spring 8 is elastically supplied to the cold air passage 7 provided between the evaporator 4 and the grill plate 6 which is discharged from the evaporator 4 by the fan 5 and interlocked with the refrigerating chamber 2. It is configured to close the refrigerating compartment (2) by installing a switching shot 10, which is operated by the installed switching knob (9) to completely block the passage flowing into the refrigerating compartment (2), the refrigerating compartment (2) In order to prevent the reverse flow of the cold air generated when closing the to the opening and closing plate 12 is installed in the first half of the refrigerating chamber cold air outlet passage (11).
본 고안은 위와같이 구성된 선출원에 있어 제2도에서와 같이 절환샷터(10)의 조절축(20)에 형성된 돌출암(21)의 회전에 의하여 레버(22)가 움직이면서 버턴(23)을 눌렀다 놓았다하여 스위치(SW1)가 접속 또는 개방상태가 되도록 연결하고 이 스위치(SW1)는 제3도 (a)에서와 같이 스위치(SW1)와 통상의 구동부(30)가 연결 구성된 공지의 차동 증폭부(40) 사이에 차동 증폭 제어부(50)를 구성시키고, 이 차동증폭 제어부(50)는 저항(R1)과 발광 다이오드(LED1)가 연결된 사이에 발광 다이오드(LED2)를 접속시키며, 이들 다이오드(D1)와 저항(R2)을 통하여 트랜지스터 (Q1)의 베이스측에 접속시키고, 트랜지스터(Q1)의 콜렉터측은 통상의 차동 증폭부(40)의 저항(R4)(R5) 사이에 접속시켜 구성된 것이다.In the present invention, the button 22 is pressed and released while the lever 22 is moved by the rotation of the protrusion arm 21 formed on the control shaft 20 of the switching shotter 10 as shown in FIG. The switch SW 1 is connected or opened, and the switch SW 1 is connected to the switch SW 1 and the conventional driving unit 30 as shown in FIG. The differential amplification control unit 50 is configured between the units 40, and the differential amplification control unit 50 connects the light emitting diode LED 2 between the resistor R 1 and the light emitting diode LED 1 connected thereto. the diode (D 1) and connected to the base side of the transistor (Q 1) through the resistor (R 2) and, side of the collector of the transistor (Q 1) resistance (R 4) of the conventional differential amplifier unit (40) (R 5 ) is connected to each other.
위와같이 구성된 본 고안의 작용효과를 설명하면 본 고안에서 겸용실(1)과 냉장실(2)을 모두 사용할 경우에는 제2도에서의 절환노브(9)를 개방 방향으로 절환시켜 절환노브(9)에 연동되는 조절축(20)의 회동에 의해 절환샷터(10)를 개방시키면서 냉기통로(7)를 열어주게 되며 또한 조절축(20)에 연결 설치된 돌출암(21)의 회전에 의해 레버(22)가 눌려짐에 따라 버턴(23)이 눌려지므로 스위치(SW1)의 내부접점이 접속되므로 스위치(SW1)는 접속상태가 되어 기존의 냉장고의 기능을 발휘하게 된다.Referring to the effect of the present invention configured as described above, when using the combined chamber (1) and the refrigerating chamber (2) in the present invention, the switching knob (9) in FIG. Opening the cold air passage (7) while opening the switching shot 10 by the rotation of the control shaft 20 linked to the lever 22 by the rotation of the protrusion arm 21 is connected to the control shaft (20) so) is pressed so the button 23 is pressed in accordance with the internal contact of the load switch (SW 1) connected to the switch (SW 1) is connected to the state is to function in the conventional refrigerator.
즉 제1도의 증발기(4)로부터 발생하는 냉기는 팬(5)에 의하여 그릴판(6)을 지나 겸용실(1)로 송출되어 냉동 유출통로(11')에서 증발기(4)로 순환되는 것이며, 냉장실(2)의 냉기 유입은 증발기(4)와 그릴판(6) 사이에 설치된 냉기통로(7)를 거쳐 냉장실(2)로 송출되어 냉장유출통로(11)에서 증방기(4)로 순환하게 되는 것이다.That is, the cold air generated from the evaporator 4 of FIG. 1 is sent by the fan 5 through the grill plate 6 to the combined chamber 1 and circulated from the freezing outlet passage 11 'to the evaporator 4. The cold air inflow of the refrigerating compartment (2) is sent to the refrigerating compartment (2) through the cold passage (7) installed between the evaporator (4) and the grill plate (6) and circulated from the refrigerating outlet passage (11) to the increaser (4). Will be done.
한편 냉장실(2)을 폐쇄하고자 할때에는 절환노브(9)를 “폐쇄” 위치로 하면 절환샷터(10)는 냉기통로(7)를 완전 차단시켜 냉장실(2)로의 냉기 공급을 중단하고 용적이 적은 겸용실(1)을 광범위 온도 조절기(13)에 의하여 냉동 및 냉장으로 절환하여 증발기(4)로부터 발생하는 냉기를 팬(5)에 의하여 겸용실(1)에 송출시켜 냉동 유출통로(11')를 통하여 증발기(4)로 순환하게 되는 것이다.On the other hand, when closing the refrigerating compartment (2), if the switching knob (9) to the "closed" position, the switching shotter 10 completely blocks the cold passage (7) to stop the cold air supply to the refrigerating compartment (2) and the volume The combined chamber (1) is switched to freezing and refrigeration by the wide-range temperature controller (13), and the cold air generated from the evaporator (4) is sent out to the combined chamber (1) by the fan (5) and the freezing outlet passage (11 ') It is to be circulated to the evaporator (4) through.
따라서 본 고안에서 절환노브(9)를 개방 또는 폐쇄방향으로 절환시키면 이에 연동된(제3도 b) 스위치(SW1)가 접속 또는 개방상태가 되는 것으로 냉동실이 냉동실 혹은 냉장실로 전환 될때마다 발광 다이오드(LED1)(LED2)에 의하여 이를 알려줄 수 있도록 구성되어 있으며, 냉기통로(7)가 개방되어 있는 평상시에는 스위치(SW1)가 접속되어 있어 기존의 냉장고의 기능을 발휘할 수 있는 것으로, 발광 다이오드(LED2)와 다이오드(D1)의 양단 전압보다 발광 다이오드(LED1)의 전압이 낮게 설정되어 있어 전원(VCC)은 발광 다이오드(LED1)를 점등시켜 평상시의 냉장고 상태를 알려줄 수 있으며, 온도 비교기(U)의 단자에인되는 전압은가 되어 저항 (R4+R5)의 값과 냉장실의 써어미스터(TH)의 저항 값(RTH라 칭함)과 같게 된다면 기존의 냉장고와 같이 온도 비교기(U)에서 써어미스터(TH)의 감지된 상태 신호에 따라 차동 증폭부(40)가 제어되어 구동부(30)가 구동됨으로 냉동실은 통상의 온도인 -19℃의 냉동상태를 유지할 수 있는 것이다.Therefore, in the present invention, when the switching knob 9 is switched in the open or closed direction, the switch SW 1 interlocked thereto (Fig. 3b) is connected or opened, so that the light emitting diode is switched to the freezer compartment or the refrigerator compartment every time. (LED 1 ) (LED 2 ) is configured to inform this, the cold air passage (7) is normally open, the switch (SW 1 ) is connected to exhibit the function of the existing refrigerator, Since the voltage of the light emitting diode (LED 1 ) is set lower than the voltages between the diodes (LED 2 ) and the diode (D 1 ), the power supply (VCC) turns on the light emitting diode (LED 1 ) to inform the normal refrigerator status. , The voltage at the terminal of the temperature comparator (U) Is equal to the value of the resistance (R 4 + R 5 ) and the resistance value of the thermistor (TH) in the refrigerating chamber (referred to as RTH), then the detected temperature of the thermistor (TH) in the temperature comparator (U) The differential amplifier 40 is controlled according to the status signal, so that the driving unit 30 is driven so that the freezing chamber can maintain a freezing state of -19 ° C, which is a normal temperature.
이와같이 냉장실의 냉기통로(7)를 개방시키고 냉동실을 냉동실로 사용하는 일반적인 냉장고에서 필요에 따라 냉장실의 냉기통로(7)를 폐쇄시키고 냉동실을 냉장실로 사용하고자 할 때에는 사용자가 제2도에 도시한 절환노브(9)를 폐쇄방향으로 절환시켜 절환노브(9)에 연동되는 조절축(20)의 회동에 의해 절환샷터(10)를 폐쇄시키면서 조절축(20)에 연결 설치된 돌출암(21)의 회전에 의해 레버(22)가 놓아짐에 따라 버턴(23)이 놓아지므로 스위치(SW1)의 내부 접점이 개방되므로 제3도 (a)의 스위치 (SW1)가 개방되어 전원(VCC)이 저항(R1), 발광 다이오드(LED2) 및 다이오드(D1)를 통하여 트랜지스터(Q1)의 베이스에 인가되므로 트랜지스터(Q1)가 도통되면서 발광 다이오드(LED2)가 점등되어 현재 기점의 냉장실은 폐쇄되고 냉동실이 냉장실로(냉동 냉장실) 사용되고 있음을 알려줄 수가 있으며 트랜지스터(Q1)가 도통되면 A점은 OV가 되어 온도비교기(U)의 단자(+)에는(저항 R7은 극히 적은 값이다)의 전압이 인가되고, 온도 비교기 (U)의 단자(-)에는의 전압이 인가된다.As described above, when the user wants to close the cold passage 7 of the refrigerating compartment and use the freezer as the refrigerating chamber in a general refrigerator using the freezer passage 7 of the refrigerating compartment and using the freezer compartment as a freezer compartment, the user switches to FIG. Rotation of the protruding arm 21 connected to the control shaft 20 while closing the switching shotter 10 by rotating the control shaft 20 interlocked with the switching knob 9 by switching the knob 9 in the closing direction. As the lever 22 is released by the button 23 is released, the internal contact of the switch SW 1 is opened, so the switch SW 1 of FIG. 3 (a) is opened so that the power supply VCC is resisted. (R 1), a light emitting diode (LED 2) and a diode (D 1) a via is applied to the base of the transistor (Q 1) so as the transistor (Q 1) conducting light emitting diode (LED 2) lights up to the current starting point refrigerating compartment Is closed and the freezer is used as a freezer (freezer) And that the number of transistors and inform (Q 1) when the point is A, the terminal (+) of the temperature comparator (U) is a conductive OV (Resistance R 7 is an extremely small value) and a voltage is applied to the terminal (-) of the temperature comparator (U). Is applied.
따라서 냉동실의 온도가 높을 경우에는 단자(+)에 단자(-)보다 높은 전압이 인가되어 온도비교기(U)의 출력은 고전위(HIGH) 상태가 되어 저항(R8)을 통하여 트랜지스터(Q2)의 베이스에 인가되어 트랜지스터(Q2)가 도통되고 이에따라 릴레이(RL)가 여자되어 스위치(SW2)가 접속되어 콤프레샤(COMP)가 구동되는 것이다.Therefore, when the temperature of the freezer compartment is high, a voltage higher than that of the terminal (-) is applied to the terminal (+), so that the output of the temperature comparator (U) becomes a high potential (HIGH) state and the transistor (Q 2 ) through the resistor (R 8 ). Is applied to the base of the transistor), and the transistor Q 2 is conducted. Accordingly, the relay RL is excited and the switch SW 2 is connected to drive the compressor COMP.
이와같이 콤프레샤(COMP)가 구동되어 냉동실의 온도가 내려가면 써어미스터 (TH)의 저항값(RTH)이 증가되어 저항(R4) 값보다 커지면서 온도 비교기(U)의 단자 (-)에 단자(+)보다 높은 전압이 인가되어 그의 출력은 저 전위(LOW) 상태가 되므로 트랜지스터(Q2)와 릴레이(RL)는 “오프”되는 것이다.In this way, when the compressor (COMP) is driven and the temperature of the freezer is lowered, the resistance value (RTH) of the thermistor (TH) is increased to be larger than the resistance (R 4 ) value, and the terminal (+) is connected to the terminal (-) of the temperature comparator (U). The transistor Q 2 and the relay RL are " off "
결국 이때에 저항(R4)의 값과 냉장고의 써어미스터의 저항 값(RTH)을 냉장고의 통상실온인 3℃로 일치시킨다면 냉동실은 냉장실의 실온과 일치되어 냉장고의 냉장실이 폐쇄될 때에 냉동실은 냉장실로 사용 할수가 있는 효과가 있는 것이다.Finally, if the value of the resistance (R 4 ) and the resistance value (RTH) of the thermistor of the refrigerator are matched to the normal temperature of the refrigerator at 3 ° C, the freezer is matched to the room temperature of the refrigerator and the freezer is closed when the refrigerator is closed. It can be used as an effect.
따라서 본 고안의 써어미스터(TH)는 냉동실을 냉동실로 사용할때에는 저항 (R4+R5)의 값과 써어미스터(TH)의 저항값이 일치되도록 하여야하며 냉동실을 냉장실로 사용하고자 할때에는 저항(R4)의 값과 써어미스터(TH)의 값이 일치되게끔 각 저항 (R4,R5) 및 써어미스터(TH)의 온도에 따른 저항 값(RTH)을 일치시킬 필요가 있는 것이다.Therefore, the thermistor (TH) of the present invention should match the value of the resistance (R 4 + R 5 ) and the resistance of the thermistor (TH) when the freezer is used as a freezer compartment. the value of the value of sseoeo Mr (TH) of R 4) being matched gekkeum there is a need to match the resistance (RTH) according to the temperatures of the respective resistors (R 4, R 5) and sseoeo Mr (TH).
이상에서와 같이 본 고안은 냉장실을 절환노브(9)에 의하여 개방시켜 통상의 냉장고와 같이 사용하고자 할때에는 스위치(SW1)가 접속되어 발광 다이오드(LED)가 점등되므로 현재의 냉장실 사용여부를 알려줄 수 있음과 동시에 통상의 냉장고로서 사용할 수 있으며, 냉장실을 폐쇄시켜 냉동실을 냉장실로 사용하고자 할때에는 절환노브(9)에 의하여 절환샷터(10)를 폐쇄시킴과 동시에 스위치(SW1)가 개방되어 발광 다이오드 (LTD1)는 소등상태가 되고 반면 발광 다이오드(ITD2)가 점등되므로 냉동실은 때장실로 사용하고 있는것을 알려주게 되며, 저항(R4)과 써어미스터(TH)의 저항값이 일치되므로 냉동실을 냉장실로 사용할 수 있으므로 냉장실이 폐쇄가능한 냉동 냉장 겸용 냉장고를 제공할 수 있는 것이다.As described above, the present invention opens the refrigerating compartment by the switching knob 9 and when the switch is to be used as a normal refrigerator, the switch (SW 1 ) is connected to the light emitting diode (LED) so that the current refrigerating compartment is used. At the same time, the refrigerator can be used as a normal refrigerator, and when the refrigerator is closed and the freezer is to be used as a refrigerator, the switch SW 1 is closed by the switching knob 9 and the switch SW 1 is opened to emit light. Since the diode (LTD 1 ) is turned off while the light emitting diode (ITD 2 ) is turned on, the freezer tells us that it is used for a long time, and the resistance value of the resistor (R 4 ) and thermistor (TH) are the same. Since the freezer compartment can be used as a refrigerating compartment, it is possible to provide a freezer and refrigerator which can be closed.
