도 1은 본 고안이 설치되는 일반적인 냉장고를 보인 단면도 로써, 종래와 동일한 부분, 부재에 대해서는 동일 부재번호를 사용한다.1 is a cross-sectional view showing a general refrigerator in which the present invention is installed, and the same parts and members are used for the same parts and members as in the prior art.
본 고안이 설치되는 냉장고의 일반적인 구성은 종래의 기술에서 상술했던 바와 동일하므로, 이에 대한 별도의 설명은 생략하고, 단지, 본 고안의 특징부인 이격수단에 대해서만 한정하여 설명한다.Since the general configuration of the refrigerator to which the present invention is installed is the same as described above in the related art, a separate description thereof will be omitted, and only limited to the separation means which is a feature of the present invention.
부연하면, 본 고안에 따른 이격수단에 대해서는 도면부호 "90"을 부여하여 설명한다.In other words, the separation means according to the present invention will be described with reference to "90".
즉, 본 고안이 적용되는 상기 회전날개(71)는 단일의 축(72)에 소정의 간격을 두고 설치되며, 그 상단부는 상술했던 상기 구동모터(73)에 축설되고, 하단부는 상기 냉기덕트(80)의 내부 하측면에 이격수단(90)에 의해 축설된다.That is, the rotary blade 71 to which the present invention is applied is installed at a predetermined interval on a single shaft 72, the upper end of which is installed in the driving motor 73, and the lower end of the cold air duct ( On the inner lower side of the 80 is arranged by the spacing means (90).
상기 이격수단(90)은 상기 회전날개(71)의 하단부에 구비된 제1 자석(91)과, 상기 제1 자석(91)과 상응하는 상기 냉기덕트(80)의 상측에 게재된 제2 자석(92)으로 구비된다.The separation means 90 includes a first magnet 91 provided at a lower end of the rotary blade 71 and a second magnet disposed above the cold air duct 80 corresponding to the first magnet 91. 92 is provided.
이를 만족시키기 위해서는, 상기 제1,2 자석(91)(92)은 그 마주하는 극성이 동일한 극성을 가져야 할 것이다.In order to satisfy this, the first and second magnets 91 and 92 should have the same polarity as their opposite polarities.
바람직하게는, 상기 제1,2 자석(91)(92)은 상기 회전날개(71)와 상기 냉기덕트(80)의 상측면에 각각 부착되어 구비될 수 있지만, 상기 회전날개(71)의 하단부와 상기 냉기덕트(80)의 상측에 각각 그 표면이 노출되게 매입되도록 구비됨이 바람직하다.Preferably, the first and second magnets 91 and 92 may be attached to upper surfaces of the rotary blade 71 and the cold air duct 80, respectively, but the lower end of the rotary blade 71 may be provided. And it is preferred that the upper surface of the cold air duct 80 is embedded so as to expose the surface, respectively.
이와 같이 구성된 본 고안의 작용 및 효과에 대해 설명한다.The operation and effects of the present invention configured as described above will be described.
도 1과 같이, 처음, 구동모터(73)가 구동되며 상기 냉기 분배수단(70)의 주된 기능을 하는 상기 회전날개(71)를 회전시키게 되면, 상기 유로(21)와 상기 냉기덕트(80)에 형성된 도시되지 않은 유로를 통해 유입된 냉기는 상기 분배그릴(74)에 형성된 토출공을 통하여 냉장실의 내측으로 토출되며, 피 보관물에 대해 상술했던 일반적인 냉장고와 마찬가지로 냉각하게 된다.As shown in FIG. 1, when the driving motor 73 is driven to rotate the rotary blade 71 serving as a main function of the cold air distributing means 70, the flow path 21 and the cold air duct 80 are rotated. The cold air introduced through the flow path (not shown) formed in the discharge chamber is discharged into the refrigerating chamber through the discharge hole formed in the distribution grill 74, and is cooled like the general refrigerator described above with respect to the object to be stored.
다만, 본 고안에서의 특징부는, 상기 구동모터(73)의 구동력에 의해 상기 회전날개(71)가 회전될 때, 회전날개(71)의 하단면과 냉기덕트(80)의 상측면 사이에서 마찰이 발생되지 않는다는 점이다.However, the feature in the present invention, when the rotary blade 71 is rotated by the driving force of the drive motor 73, the friction between the lower surface of the rotary blade 71 and the upper surface of the cold air duct (80). Is that it does not occur.
즉, 축(72)의 가장 하측에 구비된 회전날개(71)의 하단면에는 제1 자석(91)의 표면이 노출되도록 일부 매입되고, 회전날개(71)가 축설되는 상기 냉기덕트(80)의 상측면에는 상기 제1 자석(91)과 동일한 극성을 갖는 제2 자석(92)이 그 표면이 노출된 상태에서 매입된 구조에 기인하여, 상기 제1,2 자석(91)(92)에서는 상호 밀어내려는 자력이 작용되며 회전날개(71)의 하단면과, 그 회전날개(71)가 축설되는 냉기덕트(80)의 상측면 사이에는 소정의 간격을 두고 이격된다는 점이다.That is, the cold air duct 80 is partially embedded in the lower end surface of the rotary blade 71 provided at the lowermost side of the shaft 72 so that the surface of the first magnet 91 is exposed, and the rotary blade 71 is built up. Due to the structure in which the second magnet 92 having the same polarity as that of the first magnet 91 is embedded on the upper side of the first magnet 91, the first and second magnets 91 and 92 The magnetic force to be pushed out mutually is applied and is spaced apart by a predetermined interval between the lower surface of the rotary blade 71 and the upper surface of the cold air duct 80, the rotary blade 71 is built up.
따라서, 종래와 같이, 구동모터의 구동력에 의해 냉기를 분배하는 냉기 분배수단인 회전날개가 회전될 때 냉기덕트에 설치되는 회전날개의 하단면과 와셔 그리고 와셔의 하측면과 냉기덕트의 상측면 사이에서 면접촉되며 마찰이 유발되고, 또, 그에 따라 냉기를 분배시키기 위한 냉기 분배수단의 원활한 회전을 방해하게 되어 냉기의 분배효율이 저하되었던 문제점은 적극적으로 해결된다.Therefore, as in the related art, when the rotary blades, which are cold air distribution means for distributing cold air by the driving force of the driving motor, are rotated between the lower surface of the rotary blade and the washer and the lower surface of the washer and the upper surface of the cold air duct, In the surface contact and friction is caused, and thus, the problem that the distribution efficiency of the cold air is lowered by preventing the smooth rotation of the cold air distribution means for distributing the cold air is actively solved.
이상에서와 같이 본 고안에 따른 냉장고의 회전날개 지지장치에 의하면, 냉장고의 내부에 대해 냉기를 분배하는 회전날개의 회전을 원활하게 함으로써, 냉장고의 냉기 분배효율이 향상되는 등의 특징이 있다.As described above, according to the rotating blade support apparatus of the refrigerator according to the present invention, by smoothly rotating the rotation blade for distributing the cold air to the inside of the refrigerator, there is a feature such as improving the cold air distribution efficiency of the refrigerator.
본 고안은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구 범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 기술 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 청구 범위 기재의 범위내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiment, 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.
