본 발명은 냉장고에 관한 것으로, 더욱 상세하게는 냉기유로를 개폐하는 댐퍼장치를 갖춘 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly to a refrigerator having a damper device for opening and closing the cold air flow path.

일본 공개특허공보 2005-69646호에 개시된 냉장고는 상부에 냉장실이 형성되고 하부에 냉동실이 형성된 본체를 구비한다. 이 냉장고의 냉동실 후방에는 냉동실 및 냉장실의 냉각을 위한 증발기가 설치되어 있다. 냉장실 후방에는 증발기를 통해 냉각된 공기를 내장실 쪽으로 공급하기 위한 냉기유로가 형성되어 있고, 냉기유로에는 냉기공급을 제어하기 위한 댐퍼장치가 설치되어 있다.The refrigerator disclosed in Japanese Patent Laid-Open No. 2005-69646 has a main body in which a refrigerating chamber is formed at an upper portion and a freezing chamber is formed at a lower portion thereof. Behind the freezer compartment of the refrigerator is an evaporator for cooling the freezer compartment and the refrigerating compartment. A cold air flow passage is formed at the rear of the refrigerating compartment to supply the air cooled through the evaporator to the interior compartment, and a damper device is provided at the cold air flow passage to control the cold air supply.

댐퍼장치는 냉기유로에 회전 가능하게 설치된 개폐판과, 냉기유로의 개폐를 위해 개폐판을 정방향 또는 역방향으로 회전시키는 스탭모터를 포함한다. 스탭모터의 축은 개폐판에 직결된 형태이다. 이러한 댐퍼장치는 냉장실의 온도가 제어 상한 온도로 상승할 때 스탭모터가 개폐판을 회전시켜 냉기유로를 개방하고, 냉장실의 온도가 제어 하한 온도로 내려갈 때 스탭모터가 개폐판을 역으로 회전시켜 냉기유로를 폐쇄한다. 이처럼 댐퍼장치는 냉장실의 냉기공급을 조절함으로써 냉장실이 설정한 온도범위로 유지되도록 한다.The damper device includes an opening and closing plate rotatably installed in the cold air flow path, and a step motor for rotating the opening and closing plate in the forward or reverse direction to open and close the cold air flow path. The shaft of the stepper motor is directly connected to the opening and closing plate. Such a damper device has a stepper motor rotating the switchboard to open the cold air flow path when the temperature of the refrigerating chamber rises to the control upper limit temperature, and the stepper motor rotates the switchboard in reverse when the temperature of the refrigerating chamber lowers to the control lower limit temperature. Close the flow path. In this way, the damper device adjusts the cold air supply of the refrigerating compartment so that the refrigerating compartment is maintained at the set temperature range.

그러나 이러한 냉장고의 댐퍼장치는 개폐판을 정회전 또는 역회전시키거나 개폐판의 회전각을 제어하기 위해 가격이 비싼 스탭모터를 채용한 것이기 때문에 제조원가가 높은 결점이 있었다. 또 스탭모터의 동작제어를 위해서는 스탭모터에 직류전원을 인가하기 위한 D/C컨버터가 필요하기 때문에 냉장고의 구성이 복잡하였다.However, the damper device of the refrigerator has a drawback in that the manufacturing cost is high because it employs an expensive step motor to rotate the switchboard forward or reverse or control the rotation angle of the switchboard. In addition, since the D / C converter for applying DC power to the step motor is necessary for the operation control of the step motor, the configuration of the refrigerator is complicated.

또 이러한 댐퍼장치는 하나의 유로만을 개폐할 수 있기 때문에 복수의 공간 으로 선택적인 냉기공급이 필요한 냉장고의 경우 각각 별도의 스탭모터를 갖춘 댐퍼장치를 복수개소에 설치해야 했다. 이는 냉장고 제조비용 상승의 원인이 되었다.In addition, since the damper device can open and close only one flow path, it is necessary to install a damper device having a separate step motor in a plurality of places in the case of a refrigerator which needs to selectively supply cold air to a plurality of spaces. This caused the increase in the manufacturing cost of the refrigerator.

This is to enable the opening and closing plate 31 to close the refrigerating chamber cold air flow passage (21) unless an external force is applied to the opening and closing plate (31). 3 illustrates a case in which the opening and closing plate 31 is installed in the cold air duct 21, but the opening and closing plate 31 is a rear wall or an inner panel 22 of the refrigerator main body 10 defining the refrigerator compartment cold air flow passage 21. It can also be coupled to the) side.

회전캠(32)은 교류모터(33)의 축에 결합되는 회전판(32a)과, 회전판(32a)의 테두리부분으로부터 교류모터(33)의 축방향으로 돌출하며 회전판(32a)의 원주방향으로 일부구간 형성된 돌출부(32b)를 포함한다. The rotary cam 32 protrudes in the axial direction of the alternating-current motor 33 from the edge of the rotating plate 32a coupled to the shaft of the alternating-current motor 33 and partially rotates in the circumferential direction of the rotating plate 32a. It includes a section formed protrusion 32b.

굴절축(34)은 냉기덕트(21) 또는 냉장고 본체(10) 내부에 마련된 지지부(36)에 의해 회전 가능하게 지지되는 회전지지부(34a)와, 회전지지부(34a)의 양단에 각각 마련되며 회전중심과 편심되도록 굴절된 제1굴절부(34b) 및 제2굴절부(34c)를 포함한다. The refractive shaft 34 is provided at both ends of the rotation support part 34a rotatably supported by the support part 36 provided in the cold air duct 21 or the refrigerator main body 10 and the rotation support part 34a, respectively. And a first refractive portion 34b and a second refractive portion 34c refracted to be eccentric with the center.

제1굴절부(34b)는 회전지지부(34a)로부터 수회 굴절되어 형성되며 그 단부가 개폐판(31) 상면의 걸림부(31b)와 결합된다. 이는 굴절축(34)의 정/역방향 회전에 의해 제1굴절부(34b)가 회전할 때 개폐판(31)의 개폐가 이루어지도록 한 것이다. The first refraction portion 34b is formed by refraction several times from the rotation support portion 34a, and an end thereof is coupled to the locking portion 31b on the upper surface of the opening and closing plate 31. This is to open and close the opening and closing plate 31 when the first refractive portion 34b is rotated by the forward / reverse rotation of the refractive axis 34.

제2굴절부(34c)는 회전지지부(34a)로부터 굴절되어 형성되며 그 단부가 회전캠(32)의 상면에 놓인다.The second refraction portion 34c is formed by refraction from the rotation support portion 34a and its end is placed on the upper surface of the rotary cam 32.

따라서 본 발명의 댐퍼장치(30)는 도 3에 도시한 바와 같이, 교류모터(33)의 동작에 의해 회전캠(32)이 일방향으로 회전하면, 제2굴절부(34c)가 회전캠(32)의 회전판(32a) 상부에 위치하거나, 회전캠(32)의 돌출부(32b) 상부에 위치하게 된다. Accordingly, in the damper device 30 of the present invention, as shown in FIG. 3, when the rotation cam 32 rotates in one direction by the operation of the AC motor 33, the second refraction portion 34c rotates the rotation cam 32. ) Is positioned above the rotating plate 32a or above the protrusion 32b of the rotary cam 32.

즉 회전캠(32)이 회전하면, 굴절축의 제2굴절부(34c)가 상하로 이동하면서 굴절축(34)의 회전을 유발하므로 굴절축(34)의 제1굴절부(34b)와 연결된 개폐판(31)이 상하로 회전하면서 냉장실 냉기유로(21)를 개폐한다. That is, when the rotating cam 32 rotates, the second refractive portion 34c of the refraction axis moves up and down, causing the rotation of the refraction axis 34 to be opened and closed connected to the first refraction portion 34b of the refraction axis 34. The plate 31 rotates up and down to open and close the refrigerating compartment cold air flow passage 21.

굴절축(34)의 제2굴절부(34c)가 회전판(32a) 상면과 접할 때는 개폐판(31)이 하부로 회전하여 냉장실 냉기유로(21)를 폐쇄하고, 굴절축(34)의 제2굴절부(34c)가 돌출부(32b)의 위에 위치할 때는 개폐판(31)이 상부로 회전하여 냉장실 냉기유로(21)를 개방한다.When the second refraction portion 34c of the refracting shaft 34 contacts the upper surface of the rotating plate 32a, the opening and closing plate 31 rotates downward to close the refrigerating chamber cold air flow passage 21 and the second of the refracting shaft 34. When the refraction portion 34c is positioned above the protrusion 32b, the opening and closing plate 31 rotates upward to open the refrigerating compartment cold air flow passage 21.

회전캠(32)을 동작시키는 교류모터(33)는 회전속도를 센서를 통해 감지한 후 동작시간을 조절하는 방식으로 제어하거나, 도면에 도시하지는 않았지만 개폐판(31)의 개폐여부를 감지하는 센서를 감지정보를 토대로 제어할 수 있다The alternating current motor 33 for operating the rotating cam 32 is controlled by controlling the operation time after sensing the rotational speed through a sensor, or a sensor for detecting whether the opening / closing plate 31 is opened or closed, although not shown in the drawing. Can be controlled based on detected information

이처럼 본 발명의 댐퍼장치(30)는 회전캠(32)을 일방향으로 360도 회전시키는 동작으로도 유로의 개폐를 원활히 구현할 수 있다. 따라서 회전캠(32)의 구동원 으로 교류모터(33)를 채용할 수 있으며, 교류모터(33)의 가격이 저렴하기 때문에 댐퍼장치(30)의 제조비용을 줄일 수 있다.Thus, the damper device 30 of the present invention can smoothly implement the opening and closing of the flow path even by the operation of rotating the rotary cam 32 360 degrees in one direction. Therefore, the AC motor 33 may be employed as the driving source of the rotary cam 32, and the manufacturing cost of the damper device 30 can be reduced because the price of the AC motor 33 is low.

도 5와 도 6은 본 발명에 따른 냉장고의 제2실시 예이다. 제2실시 예의 냉장고는 도 5에 도시한 바와 같이, 상부의 냉장실(101)과 하부의 냉동실(102)을 구비한 본체(100)를 구비하며, 상부의 냉장실(101)이 구획판(103)에 의해 상측의 제1공간(104)과 하측의 제2공간(105)으로 구획된다. 또 냉장실(101) 쪽으로 냉기를 공급하기 위한 냉기유로도 제1공간(104)으로 냉기공급을 안내하는 제1냉기유로(121)와, 제2공간(105)으로 냉기공급을 안내하는 제2냉기유로(122)로 분기된다. 5 and 6 are a second embodiment of a refrigerator according to the present invention. As shown in FIG. 5, the refrigerator according to the second embodiment includes a main body 100 having an upper refrigerating compartment 101 and a lower freezing compartment 102, and the upper refrigerating compartment 101 is a partition plate 103. The upper space is partitioned into an upper first space 104 and a lower second space 105. In addition, the cold air flow path for supplying cold air toward the refrigerating chamber 101 also includes a first cold air flow passage 121 for guiding cold air supply to the first space 104 and a second cold air for guiding cold air supply to the second space 105. It branches to the flow path 122.

댐퍼장치(130)는 제1냉기유로(121)와 제2냉기유로(122)를 선택적으로 개폐한다. 이는 댐퍼장치(130)가 제1냉기유로(121)와 제2냉기유로(122)를 선택적으로 개폐하여 제1공간(104) 또는 제2공간(105)의 냉기공급을 제어함으로써 제1공간(104)과 제2공간(105)의 온도를 다르게 유지할 수 있도록 한 것이다. 이는 보관조건이 다른 저장물들을 제1공간(104)과 제2공간(105)에 구분하여 보관함으로써 저장물의 신선도를 장기간 유지하기 위함이다. 냉장실(101)의 제1 및 제2공간(104,105)의 공기는 복귀유로(106)를 통해 냉동실(102) 후방의 증발기(107) 쪽으로 복귀하며, 증발기(107)를 통해 냉각된 후 다시 냉동실(102) 또는 냉장실(101)로 공급된다. The damper device 130 selectively opens and closes the first cold air passage 121 and the second cold air passage 122. This is because the damper device 130 selectively opens and closes the first cold air flow passage 121 and the second cold air flow passage 122 to control the supply of cold air to the first space 104 or the second space 105. The temperature of the 104 and the second space 105 is to be kept different. This is to maintain the freshness of the storage for a long time by storing the storage having different storage conditions in the first space 104 and the second space 105 separately. The air in the first and second spaces 104 and 105 of the refrigerating compartment 101 returns to the evaporator 107 behind the freezing compartment 102 through the return passage 106, and after being cooled through the evaporator 107, is again stored in the freezing compartment ( 102 or to the refrigerating chamber 101.

댐퍼장치(130)는 도 6에 도시한 바와 같이, 제1냉기유로(121)에 회전 가능하게 설치된 제1개폐판(131), 제2냉기유로(122)에 회전 가능하게 설치된 제2개폐판(132), 제1 및 제2개폐판(131,132)의 개폐를 위한 회전캠(133), 회전캠(133)을 회전시키는 교류모터(134)를 포함한다. As shown in FIG. 6, the damper device 130 includes a first opening / closing plate 131 rotatably installed in the first cold air passage 121 and a second opening / closing plate rotatably installed in the second cold air passage 122. 132, a rotation cam 133 for opening and closing the first and second opening and closing plates 131 and 132, and an AC motor 134 for rotating the rotation cam 133.

또 댐퍼장치(130)는 제1개폐판(131)과 회전캠(133) 사이에 회전 가능하게 설치되며 일단이 제1개폐판(131)에 연결되고 타단이 회전캠(133)에 의해 동작하는 제1굴절축(135), 제2개폐판(132)과 회전캠(133) 사이에 회전 가능하게 설치되며 일단이 제2개폐판(132)에 연결되고 타단이 회전캠(133)에 의해 동작하는 제2굴절축(136), 제1개폐판(131)을 폐쇄방향으로 회전시키는 제1토션스프링(137), 제2개폐판(132)을 폐쇄방향으로 회전시키는 제2토션스프링(138)을 포함한다.In addition, the damper device 130 is rotatably installed between the first opening and closing plate 131 and the rotary cam 133, one end is connected to the first opening and closing plate 131 and the other end is operated by the rotary cam 133 It is rotatably installed between the first refractive shaft 135, the second opening and closing plate 132 and the rotary cam 133, one end is connected to the second opening and closing plate 132 and the other end is operated by the rotary cam 133 The second torsion spring 136, the first torsion spring 137 for rotating the first opening and closing plate 131 in the closing direction, the second torsion spring 138 for rotating the second opening and closing plate 132 in the closing direction It includes.

회전캠(133)은 제1실시 예에서의 회전캠과 동일한 형태이다. 즉 교류모터(134)의 축에 결합되는 회전판(133a)과, 회전판(133a)에 마련된 돌출부(133b)를 포함한다. 제1굴절축(135)은 제1굴절부(135a)가 제1개폐판(131)에 연결되고 제2굴절부(135b)가 회전캠(133)에 상부에 놓인다. 제2굴절축(136)은 제1굴절부(136a)가 제2개폐판(132)에 연결되고 제2굴절부(136b)가 회전캠(133) 상부에 놓인다. The rotary cam 133 has the same form as the rotary cam in the first embodiment. That is, it includes a rotating plate 133a coupled to the shaft of the AC motor 134 and a protrusion 133b provided on the rotating plate 133a. The first refraction shaft 135 has a first refraction portion 135a connected to the first opening and closing plate 131, and a second refraction portion 135b is placed on the rotary cam 133. The second refraction shaft 136 has a first refraction portion 136a connected to the second opening and closing plate 132, and the second refraction portion 136b is disposed on the rotary cam 133.

제1 및 제2굴절축(135,136)은 그 형태가 제1실시 예의 굴절축과 유사하고 동작원리도 같다. 다만 제2실시 예는 제1 및 제2굴절축(135,136)이 모두 하나의 회전캠(133)에 의하여 동작하는 점에서 제1실시 예와 다르다. 이는 하나의 교류모터(134) 동작에 의하여 제1개폐판(131)과 제2개폐판(132)이 선택적으로 개폐될 수 있도록 한 것이다. 즉 제2실시 예는 회전캠(133)이 회전하여 돌출부(133b)가 제1굴절축(135)을 상부로 회전시킬 때 제1냉기유로(121)가 개방되고, 회전캠(133)이 회전하여 돌출부(133b)가 반대 쪽 제2굴절축(136)을 상부로 회전시킬 때 제2냉기유로(122)가 개방된다. 따라서 제2실시 예는 교류모터(134)의 동작에 의해 회전 캠(133)이 360도 회전하는 동작만으로도 제1냉기유로(121)와 제2냉기유로(122)를 선택적으로 개폐할 수 있다.The first and second refractive axes 135 and 136 are similar in shape to the refractive axes of the first embodiment and have the same operation principle. However, the second embodiment differs from the first embodiment in that both the first and second refractive axes 135 and 136 operate by one rotating cam 133. This is to allow the first opening and closing plate 131 and the second opening and closing plate 132 to be selectively opened and closed by the operation of one AC motor 134. That is, in the second embodiment, when the rotary cam 133 rotates so that the protrusion 133b rotates the first refractive shaft 135 upward, the first cold air passage 121 is opened and the rotary cam 133 rotates. Thus, when the protrusion 133b rotates the opposite second refractive axis 136 upward, the second cold air flow passage 122 is opened. Accordingly, in the second embodiment, the first cold air passage 121 and the second cold air passage 122 may be selectively opened or closed only by the rotation cam 133 rotating 360 degrees by the operation of the AC motor 134.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 냉장고는 댐퍼장치의 회전캠이 360도 회전하는 동작만으로도 냉기유로를 개폐할 수 있는 구조이기 때문에 가격이 저렴한 교류모터를 채용하면서도 냉기유로의 개폐를 원활히 구현할 수 있는 효과가 있다.As described in detail above, the refrigerator according to the present invention is a structure that can open and close the cold air flow path only by rotating the rotation cam of the damper device 360 degrees to smoothly implement the opening and closing of the cold air flow path while adopting an inexpensive AC motor. It can be effective.

또한 본 발명에 따른 냉장고의 댐퍼장치는 하나의 회전캠으로 복수의 굴절축을 동작시킬 수 있고, 각 굴절축이 별도의 유로에 설치된 개폐판들을 개폐할 수 있기 때문에 하나의 교류모터를 채용하면서도 복수의 유로를 선택적으로 개폐할 수 있는 효과가 있다.In addition, the damper device of the refrigerator according to the present invention can operate a plurality of refraction shafts with one rotary cam, and because each of the refraction shafts can open and close the opening and closing plates installed in a separate flow path, a plurality of AC motors may be employed. There is an effect that can open and close the flow path selectively.

또한 본 발명은 댐퍼장치의 구동원으로 교류모터를 사용하기 때문에 댐퍼장치의 동작을 위해 교류전원을 직접 인가할 수 있다. 따라서 댐퍼장치의 동작을 위해 별도의 D/C컨버터가 필요하지 않기 때문에 냉장고의 구성을 단순화할 수 있는 효과가 있다.In addition, since the present invention uses an AC motor as a driving source of the damper device, AC power can be directly applied for the operation of the damper device. Therefore, since a separate D / C converter is not required for the operation of the damper device, the configuration of the refrigerator can be simplified.
