본 고안은 냉동 및 냉장으로 겸용할 수 있게한 겸용실과 냉장실 사이의 격벽부에 증발기를 설치하고 겸용실에 냉동용 온도 조절기 및 냉장용 온도 조절기를 스위치에 의해 절환되게 설치시킨 냉장고에 있어서 냉기 개폐판을 구동시키는 절환 노브와 같이 연결 작동되게 시간 스위치를 병설하여 겸용실을 냉동에서 냉장으로 사용시에 팬만을 일정시간 가동되게 하므로써 냉기를 공급시켜 냉장실 내의 온도 상승을 막고 냉장온도롤 유지토록 한 것이다.The present invention provides a cold air opening and closing plate in a refrigerator having an evaporator installed in the partition wall between the double room and the refrigerating room that can be used for freezing and refrigeration, and the freezing temperature controller and the refrigerating temperature controller are switched by a switch. By connecting the time switch so as to operate as a switching knob to drive the combined room to use only the fan for a certain time when used in the refrigeration to refrigeration by supplying cold air to prevent the temperature rise in the refrigerating chamber to maintain the refrigerating temperature roll.

종래의 겸용실을 냉장 및 냉동 겸용으로 사용하는 낸장고를 보면 겸용실을 낸동으로 사용하다가 냉장으로 절환하는 경우에는 겸용실의 온도가 절환 스위치의 조작으로 연결된 냉장실용 온도 조절기의 동작 온도 점까지 자연 상승하도록 기다려서 압축기의 운전을 조절하므서 겸용실을 냉장으로 절환 사용하게 하는 것으로,In the case of using a conventional double room for both refrigeration and freezing, when using the double room as a refrigerator and switching to refrigeration, the temperature of the combined room is changed to the operating temperature point of the temperature controller for the refrigerating room connected by the operation of the changeover switch. By waiting to ascend to adjust the operation of the compressor to switch to the refrigerating chamber,

이때의 자연 온도 상승시간은 2-3시간 정도 소요되며 압축기가 운전이 되지않아 식품 보관하는데 부적당하였던 것이다.At this time, the natural temperature rise time takes about 2-3 hours and was inadequate for food storage because the compressor did not operate.

본 고안은 이상과 같은 여러가지 결점을 해결하기 위하여 겸용실에 냉동용 온도 조절기와 냉장용 온도조절기를 절환 스위치에의해 절환되게 설치하고 냉기 개폐판을 구동시키는 절환 노브와 연동되게 시간 스위치를 병설하여 겸용실을 냉장으로 절환시켰을때 팬만을 일정시간 동안 가동시켜 냉장실 내에 냉기를 공급시키어 냉장온도를 유지케 하였다.In order to solve the above-mentioned shortcomings, the present invention installs a refrigerating temperature controller and a refrigerating temperature controller by a switching switch in a combined room, and combines a time switch in conjunction with a switching knob for driving a cold opening / closing plate. When the yarn was switched to refrigeration, only the fan was operated for a predetermined time to supply cold air into the fridge to maintain the refrigeration temperature.

이를 첨부도면에 의하여 설명하면 다음과 같다.This will be described with reference to the accompanying drawings.

겸용실(1)의 냉동, 냉장 겸용에 필요한 냉동용 온도조절기(2)와 냉장용 온도 조절기(3)가 설치되고 냉기통로(5)를 개폐시켜 주는 냉기 개폐판(6)이, 절환스위치(4')가 설치된 절환노브(4)에 의해 개폐되게 되여있고, 냉기 개폐판(6)이 절환노브(4)의 동축(7)에 고정된 캠(8)에 연결 강선(9)으로 연결되어 절환노브(4) 회전조절에 따라 냉기개폐판(6)이 냉기통로(5)을 개폐토록 하였다.Refrigeration temperature controller (2) and refrigeration temperature controller (3), which are necessary for the freezing and refrigeration of the combined use room (1), are provided with a cold air opening / closing plate (6) for opening and closing the cooling passage (5). 4 ') is opened and closed by the switching knob 4 is installed, the cold air opening and closing plate 6 is connected to the cam (8) fixed to the coaxial (7) of the switching knob (4) by a connecting wire (9) In accordance with the rotation control of the switching knob (4), the cold air opening and closing plate (6) to open and close the cold air passage (5).

그리고 절환노브(4)의 동축(7)에 고정된 캠(8)의 타단을 일측(10)에 유동되어 스프링(11)에 고정된 연동캠(13)에 접속 작동되게 설치하였으며, 연동캠(13)에 의해동작되는 시간스위치(12)의 접점(d)(e)(f)을 팬모우터(15), 절환스위치(4')의 접점 (c), 냉동냉장용 온도조절기(2)(3)에 각각 연결하여 겸용실(1)을 냉장으로 절환시 팬(5')을 일정시간 가동되게 하였다.And the other end of the cam (8) fixed to the coaxial (7) of the switching knob (4) flows to one side (10) was installed to be connected to the interlocking cam (13) fixed to the spring (11), the interlocking cam ( 13) the contacts d, e and f of the time switch 12 operated by the fan motor 15, the contacts c of the changeover switch 4 ', the temperature controller 2 for refrigeration and refrigerating. The fan 5 'was operated for a predetermined time when the combined room 1 was switched to refrigeration by connecting to (3).

냉각작용을 가능케하는 압축기(14), 증발기(16)와 댐퍼(17)로 구성된 것으로 미설명 부호 20은 냉장실이다.Compressor 14, the evaporator 16 and the damper 17 to enable the cooling action, 20 is a refrigeration chamber.

이와같이 된 본 고안의 작용효과를 설명하면 다음과 같다.When explaining the effect of the present invention made as follows.

겸용실(1)내에 절환노브(4)를 냉동에서 냉장위치로 돌려주면 도면 제4도에서 절환스위치(4')내부의 접점상태가 a-b에서 a-c상태로 연결되어 냉장용 온도조절기 (3)로 연결되고 도면 제2도 상태에서 절환노브(4)의 동축(7)에 고정된 캠(8)이 동축(7)을 중심으로 시계방향으로 회전하면서 제 3도와 같은 상태로 회전시켜 냉기 조절냉기 개폐판 (6)에 물려있는 연결강선(9)을 당기므로서 겸용실(1)의 냉기통로(5)에 설치된 냉기개폐판(6)이 통로를 차단하여 중발기(16)에서 발생하는 냉기가 겸용실(1)로 통하지 않게하므로 증발기(7)의 냉기전도에 의해 겸용실(1)을 냉장의 온도 영역을 사용할 수 있는 것이다.When the selector knob 4 is turned from the freezer to the refrigerating position, the contact state inside the switch 4 'in Fig. 4 is connected from ab to ac to the refrigerating thermostat (3). The cam 8, which is connected and fixed to the coaxial 7 of the switching knob 4 in the state of FIG. 2, rotates clockwise about the coaxial 7 in the same state as in FIG. As the cold air opening and closing plate 6 installed in the cold air passage 5 of the dual-use room 1 blocks the passage while pulling the connecting steel wire 9 held by the plate 6, the cold air generated in the heavy machinery 16 Since it does not pass through the mixing chamber 1, the temperature range of refrigeration of the mixing chamber 1 can be used by the cold air conduction of the evaporator 7. As shown in FIG.

이때 캠(8)이 동축(7)으로 고정된 절환노브(4)에 의해 회전할때 회전력으로 시간스위치(12)의 연동캠(13)을 회동시켜 연동캠(13)의 타단이 인장력이 우수한 스프링 (11)에 인장되며, 일축(10)을 중심으로 회동되어 시간스위치(12)을 동작시켜 시간스위치(12)의 내부 접점은 도면 제4도에서 f-d에서 e-d로 변경되어서 전원은 a-c-e-d로 공급되어 팬(15')만 구동시키므로 증발기(16)의 냉기를 압축기(14)의 운전없이 냉장실(20)에 공급하는 것이다. 그리고 시간스위치(12)의 캠(13)이 스프링 (11)의 복원력에 의해 복원되는 일정 동작시간이 지나 시간스위치(12)의 내부 접점 작동이 완료되면 접점은 다시 e-d에서 f-d로 연결되고 그후는 냉장용 온도조절기(3)에 의하여 압축기(14)와 냉기 순환팬모우터(5)을 구동하게 하므로 소정의 냉장고 역활을 하게되는 것이다.At this time, when the cam 8 is rotated by the switching knob 4 fixed by the coaxial 7, the interlocking cam 13 of the time switch 12 is rotated with the rotational force so that the other end of the interlocking cam 13 has excellent tensile force. It is tensioned by the spring 11 and rotated about one axis 10 to operate the time switch 12 so that the internal contact of the time switch 12 is changed from fd to ed in FIG. 4 and power is supplied to aced. Since only the fan 15 'is driven, the cold air of the evaporator 16 is supplied to the refrigerating chamber 20 without the compressor 14 being operated. When the internal contact of the time switch 12 is completed after a certain operating time in which the cam 13 of the time switch 12 is restored by the restoring force of the spring 11, the contact is connected again from ed to fd. The compressor 14 and the cold air circulating fan motor 5 are driven by the refrigerating temperature controller 3 to serve as a predetermined refrigerator.

따라서 종래의 겸용실을 냉동상태에서 냉장으로 절환사용할때 겸용실(1)의 자연온도 상승이 도면 제 5도(a)에 도시한 바에서와 같은 온도 특성도에서 도면 제5도 (b)와 같은 절환에 따른 온도특성을 나타나게 되는 것이다.Therefore, when the conventional combined use room is switched from refrigerated to refrigerated, the natural temperature rise of the combined use room 1 is the same as that shown in FIG. 5 (a). It will show the temperature characteristics by the same switching.

역으로 겸용실(1)을 냉장에서 냉동으로 절환할때에는 절환노브(4)를 돌려주므로서 도면 제4도에서 내부 접점이 a-c에서 a-b 로 연결되어 냉동실용 온도조절기(2)가 작동하게하고 절환노브(4)의 동축(7)에고정된 캠(8)이 도면 제2도와 같이 연결강선(9)을 느슨하게 풀어 냉기조절 냉기개폐판(6)이 냉기통로(5)에서 열리고 시간스위치(12)는 일측(10)에 물려있는 연동캠(13)이 자유로운 상태로 되어 어내부접점은 f-d로 통전되는 상태이므로 냉동용 온도조절기(2)에 의해 압죽기와 팬이 조절되는 것이다.Conversely, when switching the combined chamber (1) from refrigeration to freezing, turning the switching knob (4), the internal contact is connected from ac to ab in Fig. 4 so that the freezer temperature controller (2) operates and switches. The cam 8 fixed to the coaxial 7 of the knob 4 loosely disengages the connecting steel wire 9 as shown in FIG. 2, and the cold air control cold air opening and closing plate 6 opens in the cold air passage 5 and the time switch 12. ), The interlocking cam 13, which is bitten on one side 10, becomes free, and the inner contact point is energized by fd, so that the rolling die and the fan are controlled by the temperature controller 2 for the freezing.

이와같이 냉기 개폐판을 구동시키는 절환노브와 연결 작동되게 시간스위치를 병설하여 냉각팬을 일정시간 가동시켜 겸용실을 냉동으로 사용하다가 냉장으로 절환하여 사용하더라도 냉장실내의 온도상승을 방지하여 보관식품의 변질을 막을 수 있는 것이다.In this way, the switch is operated in conjunction with the switching knob for driving the cold air switchboard to operate the cooling fan for a certain period of time to use the combined room for freezing and then to switch to refrigeration to prevent the temperature rise in the fridge. You can stop.
