Description

냉장고의 냉각팬 회전장치Cooling fan rotator of refrigerator

본 고안은 냉장고의 냉각팬 회전장치에 관한 것으로서, 더욱 상세하게는 냉동실 고내로 냉기를 골고루 토출시켜 고내의 온도를 항상 일정하게 유지할 수 있도록 한 냉장고의 냉각팬 회전장치에 관한 것이다.The present invention relates to a cooling fan rotating device of the refrigerator, and more particularly, to a cooling fan rotating device of the refrigerator to maintain a constant temperature in the refrigerator by constantly discharging the cold air into the freezer compartment.

일반적으로, 냉장고는 제빙용기 및 냉동식품을 설정된 온도하에서 보관하기 위한 냉동실과 냉장대상물이 수납되는 냉장실로 구획되며, 냉동 및 냉장실 고내에는 냉동사이클로 순환하는 냉매에 의해서 제공된 냉기가 고내로 토출되어 식품을 장시간 보관하게 된다.In general, a refrigerator is divided into a freezing compartment for storing an ice making container and a frozen food at a set temperature, and a refrigerating compartment in which a refrigeration object is stored, and in the freezer and refrigerating compartment, cold air provided by a refrigerant circulating in a refrigeration cycle is discharged into the inside of the food. Will be stored for a long time.

이러한, 종래의 냉장고는 도 1에 도시된 바와같이, 단열구조로 제작된 냉장고 본체(10)는 냉동 및 냉장실(10a)(10b)로 구획되고, 냉장고 본체(10)의 전면에는 냉동실(10a)과 냉장실(10b)의 고내를 선택적 또는 동시에 밀폐하기 위한 냉동실 및 냉장실도어(12)(14)가 개폐 가능하게 결합되며, 냉장실(10b) 내부에는 냉장대상물을 올려놓기 위한 선반(16)들이 다층으로 장착된다.In the conventional refrigerator, as illustrated in FIG. 1, the refrigerator body 10 having a heat insulation structure is partitioned into a freezing and refrigerating chamber 10a, 10b, and a freezing chamber 10a is disposed at the front of the refrigerator body 10. The freezer compartment and the refrigerating compartment doors 12 and 14 for selectively or simultaneously sealing the inside of the refrigerator compartment 10b are opened and closed, and the shelves 16 for placing the refrigeration objects in the refrigerating compartment 10b are multi-layered. Is mounted.

냉장고 본체(10) 하단에는 저온 ·저압의 기체냉매를 고온 ·고압으로 압축시키는 압축기(18)와 기체냉매를 액화시키기 위한 응축기(도시되지않음)가 각각 설치되고, 냉동실(10a)의 내상 후면에는 압축기(18)로부터 보내진 기체냉매를 증발시켜 주위 공기를 냉각하는 증발기(20)가 설치된다.At the bottom of the refrigerator main body 10, a compressor 18 for compressing low-temperature and low-pressure gas refrigerant at high temperature and high pressure and a condenser (not shown) for liquefying the gas refrigerant are respectively installed. An evaporator 20 is installed to cool the ambient air by evaporating the gas refrigerant sent from the compressor 18.

증발기(20)의 상부에는 냉기를 냉동 및 냉장실(10a)(10b)로 강제 송풍시킬 수 있도록 냉각팬(22)이 위치된다.In the upper portion of the evaporator 20, a cooling fan 22 is positioned to force cold air to the freezing and refrigerating chambers 10a and 10b.

증발기(20)의 전방측에는 이를 보호 지지하는 증발기 커버(24)와 토출구(26a)를 갖는 덕트(26)가 각각 장착된다. 덕트(26)는 증발기 커버(24)에 대해 일정간격으로 이격되어 냉각팬(22)으로부터 송풍된 냉기를 냉동실(10a)로 토출시키기 위한 것이다.On the front side of the evaporator 20, a duct 26 having an evaporator cover 24 and a discharge port 26a for protecting and supporting the evaporator 20 is mounted. The duct 26 is for discharging the cold air blown from the cooling fan 22 to the freezing chamber 10a by being spaced at a predetermined interval with respect to the evaporator cover 24.

이와같이 구성된 종래의 냉장고는, 냉동실(10a) 내에 수납되거나 또는 냉장실(10b)에 다층으로 장착된 선반(16) 상부에 올려진 식품 등의 대상물을 냉각시켜 장시간 보관하기 위해 압축기(18)를 동작시키면, 액냉매는 캐필러리 튜브(도시되지 않음)에 의해 감압되면서 증발기(20)로 보내지고, 증발기(20)에서는 증발잠열을 빼앗아 주변의 공기를 냉각시킨다.In the conventional refrigerator configured as described above, when the compressor 18 is operated in order to cool an object such as a food stored in the freezer compartment 10a or mounted on the shelf 16 mounted in the refrigerator compartment 10b in a multi-layer and store it for a long time. The liquid refrigerant is sent to the evaporator 20 while being decompressed by a capillary tube (not shown), and the evaporator 20 takes the latent heat of evaporation to cool the surrounding air.

그 후, 냉각팬(22)이 고속 회전함에 따라 냉기는 덕트(26)에 형성된 토출구(26a)를 통하여 냉동실(10a) 내부로 토출되고, 냉장고 본체(10)에 형성된 냉기유로(10c)를 따라 흐르면서 냉장실(10b)로 토출되어 냉장대상물을 설정된 온도에서 냉각한다.Thereafter, as the cooling fan 22 rotates at high speed, the cool air is discharged into the freezing chamber 10a through the discharge port 26a formed in the duct 26, and along the cold air flow path 10c formed in the refrigerator main body 10. As it flows, it is discharged into the refrigerating chamber 10b to cool the refrigeration object at the set temperature.

그러나, 상기와 같이 냉동실의 고내로 냉기를 강제 송풍시키기 위한 냉각팬이 내상 후면에 고정 설치되었기 때문에 증발기로부터 제공된 냉기가 냉동실의 고내로 골고루 토출되지 않고, 특히 냉동실의 모서리 부위로 토출되는 냉기량이 적어 고내 전체를 균일한 온도로 유지할 수 없는 단점이 있었다.However, since the cooling fan for forcedly cooling the cold air into the freezer compartment as described above is fixedly installed on the rear of the inner box, the cool air provided from the evaporator is not evenly discharged into the freezer compartment, and in particular, the amount of cold air discharged to the corner of the freezer compartment is small. There was a disadvantage in that the entire interior of the oven could not be maintained at a uniform temperature.

또한, 냉각팬의 전방에 토출구를 갖는 별도의 덕트를 장착함에 따라서 작업 공수 및 경제적인 비용이 상승되는 문제점이 있었다.In addition, the installation of a separate duct having a discharge port in front of the cooling fan has a problem that the labor cost and economic cost is increased.

본 고안은 상기와 같은 문제점들을 해결하기 위한 것으로서, 본 고안의 목적은 냉각팬을 일정반경을 갖도록 고정시킨 다음 360°씩 반복적으로 정,역회전시키고, 증발기를 보호 지지하기 위한 증발기 커버에는 냉각팬이 회전되는 궤도에 위치되도록 토출구를 형성시킴으로써, 냉기를 토출시키기 위한 별도의 덕트가 삭제되어 작업공수 및 제조원가를 절감할 수 있고, 특히 냉동실 고내의 모서리 부위에 냉기를 충분히 토출시킬 수 있어 이에 따라 냉동실 내부의 온도를 항상 일정하게 유지시킬 수 있는 냉장고의 냉각팬 회전장치를 제공하는데 있다.The present invention is to solve the above problems, the purpose of the present invention is to fix the cooling fan to have a certain radius, and then rotates forward and backward repeatedly by 360 °, the cooling fan in the evaporator cover for protecting and supporting the evaporator By forming the discharge port so as to be located in the rotating track, a separate duct for discharging the cold air can be eliminated, thereby reducing the labor and manufacturing cost, and in particular, the cold air can be discharged sufficiently at the corners of the freezer compartment. It is to provide a cooling fan rotating device of the refrigerator capable of maintaining a constant internal temperature at all times.

이하, 본 고안에 따른 냉장고의 냉각팬 회전장치에 대한 바람직한 실시예를첨부도면에 의거하여 상세하게 설명한다.Hereinafter, a preferred embodiment of the cooling fan rotating apparatus of the refrigerator according to the present invention will be described in detail with reference to the accompanying drawings.

도 2 및 도 3은 본 고안에 따른 냉각팬 회전장치를 도시한 도면으로서, 냉장고 본체(10)는 냉동 및 냉장실(10a)(10b)로 구획되고, 냉동실(10a)의 내상 후면에는 주위의 공기를 냉각시키기 위한 증발기(20)가 설치된다.2 and 3 are views showing the cooling fan rotating apparatus according to the present invention, the refrigerator main body 10 is divided into a freezing and refrigerating chamber (10a) (10b), the inner air of the freezing chamber (10a) in the back of the surrounding air Evaporator 20 is installed to cool the.

증발기(20)의 상부에는 냉기를 냉동실(10a)의 고내로 강제 송풍시키기 위한 냉각팬(30)이 위치된다. 이 냉각팬(30)은 모터를 포함한 모터 하우징(32)과 모터의 회전축에 압입된 프로펠러(propeller)(34)로 된다.In the upper portion of the evaporator 20, a cooling fan 30 for forcibly blowing cold air into the freezer compartment 10a is located. The cooling fan 30 is composed of a motor housing 32 including a motor and a propeller 34 pressed into the rotating shaft of the motor.

냉각팬(30)은 이를 시계방향과 반시계방향으로 360°씩 반복적으로 정,역회전시키기 위한 냉각팬 회전부재에 고정되며, 냉각팬 회전부재는 냉동실(10)의 내상 후면에 형성된 결합공(10d)으로 삽입 결합된 구동모터(36)에 압입된다. 미설명부호 10d는 결합공이다.The cooling fan 30 is fixed to the cooling fan rotating member for rotating it forward and backward repeatedly by 360 ° clockwise and counterclockwise, and the cooling fan rotating member is coupled to the coupling hole formed on the inner back of the freezing chamber 10 ( 10d) is pressed into the drive motor 36 inserted into the coupling. Reference numeral 10d is a coupling hole.

냉각팬 회전부재는 구동모터(36)의 회전축(36a)에 압입된 회전판(38)과 회전판(38)의 중심으로부터 일정거리로 이격된 위치에 장착되어 냉각팬(30)을 일정반경의 궤도로 회전시키기 위해 모터 하우징(32)이 고정되는 홀더(40)로 구비된다.The cooling fan rotating member is mounted at a position spaced apart from the center of the rotating plate 38 and the rotating plate 38 press-fitted to the rotating shaft 36a of the drive motor 36 to move the cooling fan 30 into a raceway having a predetermined radius. It is provided with a holder 40 to which the motor housing 32 is fixed for rotation.

회전판(38)에는 홀더(40)와 근접되도록 관통공(38a)이 형성되어 있고, 관통공(38a)에는 냉각팬(30)으로 전원을 인가하기 위한 와이어(42)가 관통되며, 이 와이어(42)는 회전판(38)의 배면에서 클립(44)에 의해 고정된다.A through hole 38a is formed in the rotating plate 38 so as to be close to the holder 40, and a wire 42 for applying power to the cooling fan 30 passes through the through hole 38a. 42 is fixed by the clip 44 on the back of the rotating plate 38.

여기에서, 구동모터(36)는 회전판(38)을 시계 및 반시계방향으로 360°씩 반복적으로 회진시키기 위해 마이컴(도시되지않음)에 의해 제어되는 스텝핑 모터가 사용된다. 구동모터(36)의 정,역회전은 회전판(38)의 회전시 냉각팬(30)으로 전원을 인가하기 위한 와이어(42)의 꼬임을 방지하기 위한 것이다.Here, the drive motor 36 is a stepping motor controlled by a microcomputer (not shown) to repeatedly rotate the rotating plate 38 by 360 ° clockwise and counterclockwise. Forward and reverse rotation of the drive motor 36 is to prevent the twisting of the wire 42 for applying power to the cooling fan 30 during the rotation of the rotary plate (38).

냉각팬(30)의 전방에는 증발기(20)를 보호 지지함과 동시에 냉동실(10a) 고내로 냉기를 토출시킬 수 있도록 다수의 토출구(46a)를 갖는 증발기 커버(46)가 장착되며, 토출구(46a)는 냉각팬(30)이 회전하는 궤도에 위치되도록 원형상으로 배열된다.In front of the cooling fan 30, an evaporator cover 46 having a plurality of discharge ports 46a is mounted to protect and support the evaporator 20 and discharge cold air into the freezer compartment 10a. ) Is arranged in a circular shape so that the cooling fan 30 is located in a rotating track.

상기와 같이 구성된 본 고안에 따른 냉장고의 냉각팬 회전장치에 대한 작용을 도4를 참조하여 상세하게 설명한다.The operation of the cooling fan rotating apparatus of the refrigerator according to the present invention configured as described above will be described in detail with reference to FIG.

냉동 및 냉장실(10a)(10b) 내부에 냉각대상물을 수납한 후 압축기(18)를 동작시키면, 저온 ·저압의 기체냉매가 고온 ·고압으로 변환되어 응축기로 보내진다. 응축기에서 응축된 액냉매는 캐필러리 튜브를 따라 감압되면서 증발기(20)로 흐르고, 증발기(20)에서는 주변의 공기를 냉각시킨다.When the compressor 18 is operated after storing the object to be cooled in the freezing and refrigerating chambers 10a and 10b, the low-temperature and low-pressure gas refrigerant is converted into high-temperature and high-pressure and sent to the condenser. The liquid refrigerant condensed in the condenser flows to the evaporator 20 while being decompressed along the capillary tube, and the evaporator 20 cools the surrounding air.

그 후, 냉각팬(30)은 이에 연결된 와이어(42)를 통해 인가된 전원에 의해서 회전되기 시작하고, 구동모터(36)의 기동에 따라 일정한 궤도로 회전하면서 증발기 커버(46)에 원형상으로 배열되도록 형성되어 있는 토출구(46a)를 통해 토출되므로 냉기를 냉동실(10a) 내부로 골고루 토출시킬 수 있어 고내 전체의 온도를 항상 일정하게 유지할 수 있는 것이다.Thereafter, the cooling fan 30 starts to rotate by the power applied through the wire 42 connected thereto, and rotates in a constant orbit according to the operation of the driving motor 36 in a circular shape on the evaporator cover 46. Since it is discharged through the discharge port 46a which is formed to be arranged, it is possible to evenly discharge cold air into the freezing chamber 10a, so that the temperature of the whole inside of the refrigerator can be kept constant at all times.

즉, 냉동실(10a)의 내상 후면에 결합된 구동모터(36)는 마이컴의 제어신호에 의해서 반복적으로 정,역회전함에 따라 구동모터(36)의 회전축(36a)에 압입된 회전판(38)을 시계 및 반시계방향으로 회전시키고, 이와 동시에 회전판(38)의 홀더(40)에 모터 하우징(32)이 고정된 냉각팬(30)은 일정한 반경의 궤도로 회전된다.That is, the driving motor 36 coupled to the inner surface rear surface of the freezing compartment 10a repeatedly rotates forward and backward by the control signal of the microcomputer, thereby rotating the rotating plate 38 press-fitted to the rotation shaft 36a of the driving motor 36. The cooling fan 30, which is rotated clockwise and counterclockwise, and at which the motor housing 32 is fixed to the holder 40 of the rotating plate 38, is rotated in a raceway of a constant radius.

이때, 냉각팬(30)에 연결된 와이어(42)는 회전판(38)이 시계 및 반시계방향으로 회전됨에 따라 회전축(36a)에 대해 꼬이는 것이 방지된다.At this time, the wire 42 connected to the cooling fan 30 is prevented from twisting about the rotating shaft 36a as the rotating plate 38 is rotated clockwise and counterclockwise.

따라서, 냉기는 냉각팬(30)이 회전하는 궤도와 동일한 위치에 원형상으로 배열되도록 형성된 토출구(46a)를 통하여 토출됨에 따라 냉동실(10a) 모서리 부위에 많은 냉기량을 공급할 수 있는 것이다.Therefore, as the cool air is discharged through the discharge port 46a formed so that the cooling fan 30 is arranged in a circular shape at the same position as the rotating track, it is possible to supply a large amount of cool air to the corner of the freezer compartment 10a.

이상에서와 같이 본 고안에 따른 냉장고의 냉각팬 회전장치에 의하면, 냉각팬을 일정반경을 갖도록 고정시킨 다음 360°씩 반복적으로 정,역회전시키고, 증발기를 보호 지지하기 위한 증발기 커버에는 냉각팬이 회전되는 궤도에 위치되도록 토출구를 형성시킴으로써, 냉기를 토출시키기 위한 별도의 덕트가 삭제되어 작업공수 및 제조원가를 절감할 수 있고, 특히 냉동실 고내의 모서리 부위에 냉기를 충분히 토출시킬 수 있어 이에 따라 냉동실 내부의 온도를 항상 일정하게 유지시킬 수 있다.As described above, according to the cooling fan rotating apparatus of the refrigerator according to the present invention, the cooling fan is fixed to have a certain radius, and then rotated forward and backward repeatedly by 360 °, and the cooling fan is provided on the evaporator cover for protecting and supporting the evaporator. By forming the discharge port so as to be located in the rotating track, a separate duct for discharging the cold air can be eliminated to reduce the labor and manufacturing cost, and in particular, it is possible to discharge enough cold air to the corner portion of the freezer compartment, thus the inside of the freezer compartment The temperature of can be kept constant at all times.

본 고안은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구 범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안 이 속하는 기술 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
