본 고안은 냉동 냉장 겸용 냉장고에 관한 것으로, 겸용실의 냉기 통기구에 개폐판을 장설하고 냉동순환로 및 냉장순환로 전방부에 개폐판을 설치하여 노브가 축착된 캠과 연결선으로 개폐판을 개폐자재되게 연결시키어 겸용실을 냉장으로 절환시킬 경우 냉장온도로 유지된 냉장실의 냉기는 겸용실로 공급순환되어 겸용실을 냉장온도로 신속히 도달하게 하였고, 냉장실의 댐퍼장치에 의하여 동작되는 온도조절 스위치와 겸용실의 온도를 조절하는 2개의 접점스위치를 갖는 겸용실 온도조절 스위치의 양단에 병렬로 연결시키고, 이를 제상 타이머와 압축기 및 팬모우터 사이에 연결하여 팬모우터와 압축기의 기등을 전기적으로 제어하도록 하여서 냉동에서 냉장으로 사용할 경우 부하적응성을 향상시키고, 또한 절환할때 발생되는 일정시간 동안의 냉장실 온도 상승의 문제점을 해결할 수 있게 한 것이다.The present invention relates to a refrigerator for combined use of refrigeration and refrigerating, install an opening and closing plate in the cold air vent of the combined room, and install the opening and closing plate in the front of the freezing circulation passage and the refrigeration circulation passage to connect the opening and closing plate to the cam and the connection line with the knob is connected When switching the combined room to refrigerating, the cold air of the refrigerating chamber kept at the refrigerating temperature was circulated to the refrigerating chamber to quickly reach the refrigerating temperature, and the temperature control switch operated by the damper of the refrigerating chamber and the temperature of the mixed room In parallel in both ends of the temperature control switch of the combined room having two contact switches to control the, and between the defrost timer and the compressor and fan motor to electrically control the fan motor and compressor, etc. When used as refrigeration, it improves load adaptability and also cools for a certain period of time during switching It will be able to solve the problems of the actual temperature.

종래에 통상의 냉장고는 냉동실과 냉장실로 별도로 설치되어서 실제적으로 사용자 입장에서 냉동실이 필요하지 않을 때에도 냉동실은 항상 저온(－10°－9－30℃ 정도)으로 냉동의 상태를 유지시키기 위하여 압축기 및 팬모우터를 가동시켜야 하므로 소비전력의 상승을 초래하는 결점이 발생하였던 것이다.Conventionally, conventional refrigerators are separately installed in the freezer compartment and the refrigerator compartment so that the freezer compartment is always kept at a low temperature (about -10 ° -9-30 ° C.) even when the freezer is not required from the user's point of view. Since the motor needs to be operated, a defect that causes an increase in power consumption has occurred.

이들 결점을 해결하고자 격벽부에 증발기가 설치된 냉장고에 있어 냉동실을 냉장으로 절환시키기 위하여 냉동실로 유입되는 냉기를 차단시켜 증발기로부터 발생하는 냉기를 전도의 냉기에 의해 냉동실을 냉장 설정온도로 유지시키게 하고 냉동실엔 냉동온도 영역용 온도조절기 이외에 냉장온도 영역용 온도조절기를 별도로 설치하여 절환스위치로 절환되게 하고 있으나 이와 같은 방식은 냉장으로 절환시 냉동실이 냉장온도로 상승되는 동안 압축기와 팬이 정지되므로 냉장실의 온도가 상승되는 폐단이 있어 냉장실은 설정온도 보다 높아 냉장실의 구실을 못하여 보관물품이 상할 염려가 있으며, 냉동실을 냉장으로 절환시킬 경우 냉기공급이 단순히 전도에 의해 공급되어 부하적응성이 좋지 못한 폐단이 있었다.In order to solve these shortcomings, in a refrigerator equipped with an evaporator in the partition wall, the cold air flowing into the freezer compartment is blocked in order to switch the freezer compartment to refrigeration so that the cold air generated from the evaporator is kept at the set temperature of the freezer compartment by the cold air of conduction. In addition to the temperature controller for the refrigeration temperature zone, a separate temperature controller for the refrigeration temperature zone is installed to switch to the changeover switch.However, in this method, the temperature of the refrigerator compartment is stopped because the compressor and the fan are stopped while the freezer compartment is raised to the refrigeration temperature. There is a fear that the refrigerator compartment is higher than the set temperature because the refrigerator is higher than the set temperature, the storage items may be damaged, and when the refrigerator is switched to the refrigerator, the cold air supply is simply supplied by conduction, resulting in poor load adaptability.

본 고안은 이상과 같은 재결점을 해결하기 위하여 겸용실의 그릴판 후면측에 형성된 단열벽에 천공된 통기구에 개폐판을 장설하고 냉동순환로 및 냉장순환로 전방부에 개폐판을 장설하여 노브가 축착된 캠과 연결선으로 연결하여 두개의 개폐판을 개폐 자재하여서 냉기의 순환을 교환하게 하였으며 냉장실의 댐퍼장치에 의하여 동작되는 온도조절 접점스위치를 겸용실의 온도조절 스위치내의 2개의 접점양단에 병렬시키고 제상 타이머와 압축기 팬모우터 사이에 연결하여 기동을 전기적으로 제어하여 냉동에서 냉장으로 사용시 부하 적응성을 향상시키고 일정시간 동안의 냉장실 온도상승을 해결한 것이다.The present invention is to install the opening and closing plate in the vent hole perforated in the insulating wall formed on the rear side of the grill plate of the combined room, and the opening and closing plate in the front of the freezing circulation path and the refrigeration circulation passage to the knob to be condensed By connecting the cam and the connecting line to open and close the two opening and closing materials to exchange the circulation of cold air, the temperature control contact switch operated by the damper device of the refrigerating compartment is parallel to the two contact points in the temperature control switch of the combined room and the defrost timer It is connected between the compressor and the fan motor to electrically control the start, thereby improving the load adaptability when using from refrigeration to refrigeration and solving the temperature rise in the refrigerator compartment for a certain time.

이와 같이 된 본 고안의 작용효과를 상술하면 다음과 같다.The effect of the present invention made as described above is as follows.

절환노브(10)를 냉동으로 절환시킬 경우 단열벽(5˝)의 통기구(4˝)에 설치된 개폐판(7)은 노브(10)에 연결된 캠(10´)에 의하여 당겨지게 되어 도면 제3도 (b)와 같이 스프링(9)이 늘어나면서 개폐판(7)이 통기구(4˝)을 열어주고 냉동순환로(4) 및 냉장순환로(4´) 전방부에 설치된 개폐판(7´)은 겸용실(5)과 냉장실(8)을 통하는 통로를 막아주게 되어 제2도에서 개폐판(7)(7´)은 가상선 상태로 되어서 증발기(3)로부터 발생하는 냉기는 팬(6)에 의해 통기구(4˝)에 유입하면서 그릴판(5´)을 통과하여 겸용실(5)로 냉기가 유통 공급하게 하여서 냉동순환로(4)를 거쳐 증발기(3)로 유입되는 것이며, 이때 겸용실(5)은 냉동온도를 유치하게 되는 것이다.In the case of switching the switching knob 10 to freezing, the opening / closing plate 7 installed in the vent hole 4 단열 of the heat insulation wall 5˝ is pulled by the cam 10 'connected to the knob 10, and the third drawing As shown in FIG. 2B, as the spring 9 is extended, the opening and closing plate 7 opens the vent hole 4 주고 and the opening and closing plate 7 ′ provided at the front of the freezing circulation passage 4 and the refrigerating circulation passage 4 ′ is In FIG. 2, the opening and closing plates 7 and 7 ′ become virtual lines so that the coolant generated from the evaporator 3 is blocked in the fan 6. By passing through the grill plate (5 ') while flowing into the vent (4˝) by the cold air flows into the mixing chamber (5) flows into the evaporator (3) through the freezing circulation passage (4), at this time 5) is to attract the freezing temperature.

또한 겸용실(5)에 유통되는 일부의 냉기는 겸용실(5) 천정일측의 그릴판(5´)과 단열벽(5˝) 사이의 통로에 형성된 유출통로(20)를 거쳐서 증발기(3)로 순환되는 것이어서 냉동온도로 설정시킨 겸용실(5)의 냉기 유통이 신속하고 원활하게 이루어지는 것이다.In addition, a part of the cold air circulated in the combined use chamber 5 passes through the outlet passage 20 formed in the passage between the grill plate 5 'and the heat insulation wall 5' on the ceiling of the combined use chamber 5, and the evaporator 3 The circulation of the cold air is quickly and smoothly performed in the combined use chamber 5 set to the freezing temperature.

그리고 냉장실(8)로 유입되는 냉기는 팬(6)에 의해 유입통로(19)를 거쳐 직접 냉장실(8)로 유통공급되어 냉장순환로(4´)를 통하여 증발기(3)로 순환하게 되는 것이다.The cold air introduced into the refrigerating chamber 8 is circulated to the evaporator 3 through the refrigerating circulation line 4 'by being circulated and supplied directly to the refrigerating chamber 8 through the inflow passage 19 by the fan 6.

한편 겸용실(5)을 냉장의 설정온도로 절환하고자 할 때에는 노브(10)을 냉장으로 절환시키면 도면 제3도 (a)와 같이 캠(10´)에 연결된 연결선(10˝)에 의해 개폐판 (7)은 스프링(9)의 복원력으로 닫혀지게 하여 통기구(4˝)를 막아주게 되며, 냉동순환로(4) 및 냉장순환로(4´) 전방부에 설치된 개폐판(7´)은 스프링(9´)이 늘어나 겸용실(5)과 냉장실(8)을 서로 통하게 도면 제2도 개폐판(7)(7´)의 실선상태로 되어서 증발기(3)로부터 발생하는 냉기는 팬(6)에 의하여 겸용실(5)측의 통기구(4˝)를 통과하지 못하고 냉장실(8)로 통하는 유입통로(19)로 유입되어 냉장실(8)로 유입된후 유통냉기는 개폐판(7´)에 의해 폐쇄된 냉장순환로(4´)를 통과하지 못하고 겸용실(5)로 상승 순환하여 냉기는 겸용실(5) 천정일측에 형성된 그릴판(5´) 사이의 유출통로 (20)를 거쳐 증발기(3)로 순환하게 되는 것이다.On the other hand, when the dual-use chamber 5 is to be switched to the set temperature of refrigeration, when the knob 10 is switched to refrigeration, the opening and closing plate is connected by a connecting line 10 'connected to the cam 10' as shown in FIG. (7) is closed by the restoring force of the spring (9) to block the vent (4˝), the opening and closing plate (7 ') provided in the front of the freezing circulation passage (4) and the refrigeration circulation passage (4') is the spring (9). ′) Is extended so that the coolant generated from the evaporator 3 is drawn to the solid state of the opening and closing plates 7 and 7 ′ of FIG. 2 through the combined chamber 5 and the refrigerating chamber 8. After passing through the intake passage (19) to the refrigerating chamber (8) without passing through the vent (4˝) on the side of the combined-use chamber (5) and flowing into the refrigerating chamber (8), the distribution cold air is closed by the opening and closing plate (7 '). The cold air is passed through the outflow passage 20 between the grill plates 5 'formed on one side of the ceiling of the combined chamber 5 without passing through the refrigerating circulation passage 4', and thus, the evaporator 3 In order It will be bright.

따라서 냉기의 유통을 냉장실(8)에서 겸용실(5)로 순환케 하므로 겸용실(5)을 냉동온도에서 냉장온도로 신속히 도달하게 되는 것이다.Therefore, the circulation of cold air is circulated from the refrigerating chamber 8 to the combined chamber 5 so that the combined chamber 5 is quickly reached from the freezing temperature to the refrigerating temperature.

여기서 냉장실(8)의 댐퍼(21)에 의하여 동작되는 온도조절 스위치와 겸용실 (5)의 온도를 조절하는 접점스위치를 겸용실 온도조절 스위치의 2개의 접점과 병렬로 연결되고 제상 타이머와 압축기(C) 및 팬모우터(14) 사이에 연결되어 기동이 전기적 제어하도록 하여 냉동에서 냉장으로 사용할 경우 부하적응성을 향상시키고 또한 절환할때 발생되는 일정시간 동안의 냉장실(8) 온도상승의 문제점을 해결한 것이다.Here, the temperature control switch operated by the damper 21 of the refrigerating chamber 8 and the contact switch for controlling the temperature of the combined chamber 5 are connected in parallel with the two contacts of the combined temperature control switch, and the defrost timer and the compressor ( C) and fan motor (14) connected to the electric control to start the electrical control to improve the load adaptability when used in refrigeration, and also solves the problem of the temperature rise of the refrigerator compartment (8) for a certain time generated during switching It is.

겸용실 온도조절용 2개의 접점스위치(T/S1) 및 (T/S´1)를 겸용실(5)내에 설치하고, 기존냉장실(8)에는 댐퍼스위치(T/S2)를 설치하여 겸용실(5) 온도조절용 접점스위치(T/S1) 및 (T/S´1)는 겸용실(5)내의 온도가 규정 냉동온도(예시 －25℃)로 냉각될때까지는 접속(ON)상태로 작동하다가 겸용실(5)내의 온도가 규정 냉동온도에 도달하게 되면 그 접점스위치(S/S1)과 (T/S´1)는 개방(OFF)상태로 된다.Two contact switch (T / S 1 ) and (T / S´ 1 ) for temperature control are installed in the combined room (5), and the damper switch (T / S 2 ) is installed in the existing refrigerator compartment (8). (5) Temperature control contact switches (T / S 1 ) and (T / S´ 1 ) remain connected (ON) until the temperature in the combined room (5) cools to the specified freezing temperature (eg -25 ° C). During operation, when the temperature in the combined-use chamber 5 reaches the specified freezing temperature, the contact switches S / S 1 and T / S´ 1 are turned OFF.

접점스위치(T/S1)과 (T/S´1)가 개방(OFF)상태가 되면 기존 냉장실내의 온도는 댐퍼(21)에 의하여 동작되는 스위치(T/S2)에 의해서 제어된다.When the contact switch (T / S 1 ) and (T / S ' 1 ) is in the open (OFF) state, the temperature in the existing refrigerator compartment is controlled by the switch (T / S 2 ) operated by the damper (21).

즉 냉장실(8)내의 온도가 규정온도 이상이 되면 댐퍼(21)는 개방되며 연동스위치(T/S2)는 접속상태가 되어 그 접점스위치(T/S1) 및 (T/S´1)의 동작상태와는 관계없이 팬을 구동시켜 증발기(3)의 냉기를 기존 냉장실(8)내로 공급하게 되며, 기존 냉장실내의 온도가 규정 냉장온도(예시＋5℃)에 도달하게 되면 댐퍼(21)의 개폐판(21´)는 폐쇄되어 연동스위치(T/S2)는 개방(OFF)상태가 되어 겸용실(5)은 냉동온도로 기존 냉장실(8)내의 냉장온도로 유지되게 된다.That is, when the temperature in the refrigerating chamber 8 is above the prescribed temperature, the damper 21 is opened and the interlock switch T / S 2 is connected to the contact switch T / S 1 and T / S´ 1 . Irrespective of the operating state of the fan, the fan is driven to supply the cold air of the evaporator 3 into the existing refrigerator compartment 8, and when the temperature in the existing refrigerator compartment reaches the specified refrigerator temperature (eg + 5 ° C.), the damper 21 The opening and closing plate 21 'of the interlock switch (T / S 2 ) is opened (OFF) state, the combined room 5 is maintained at the refrigerating temperature in the existing refrigerating chamber (8) at the freezing temperature.

만일 겸용실(5)내의 온도를 냉장실(8)내의 온도수준으로 유지하고자 할 경우는 접점스위치(T/S1) 및 (T/S´1)를 구동하는 손잡이를 냉장영역으로 돌리면, 그 접점스위치(T/S1) 및 (T/S´1)는 겸용실내의 온도가 냉장온도 영역내로 상승되는 약간의 시간동안 개방(OFF)상태가 되어 있으므로 압축기(C)는 약간의 시간동안 구동되지 않는다.If you want to keep the temperature in the combined-use room 5 at the temperature level in the refrigerating compartment 8, turn the knobs that drive the contact switches T / S 1 and T / S´ 1 to the refrigerating area. Since the switches (T / S 1 ) and (T / S´ 1 ) remain in the OFF state for a period of time when the temperature in the combined room rises into the refrigerating temperature range, the compressor (C) does not run for a period of time. Do not.

다시 기존냉장실(8)의 온도가 상승하면 댐퍼의 개폐판(21´)가 개방되어 연동스위치(T/S2)는 접속상태가 되어 겸용실(5)내의 온도가 냉장온도로 상승되는 동안은 압축기(C)가 구동되지 않더라고 팬(6)만을 작동시켜 겸용실(5)내의 냉기를 기존냉장실(8)로 공급하므로 겸용실(5)내의 온도는 신속하게 냉장온도를 상승되므로 기존냉장실(8)은 항상 규정된 온도를 정확히 유지하게 된다.When the temperature of the existing refrigerating chamber 8 rises again, the damper opening / closing plate 21 'is opened, and the interlock switch T / S 2 is connected to the refrigerator. Even though the compressor C is not driven, only the fan 6 is operated to supply the cool air in the combined use chamber 5 to the existing refrigerator 8, so that the temperature in the combined use compartment 5 quickly increases the refrigerating temperature. 8) always maintains the specified temperature accurately.
