또한, 도 4에 도시한 바와 같이, 구동축(64)의 중도에는 경사홈(61)에 끼워져 결합되어 회전날개(58)(59)의 회전운동을 구동축(64)의 상하 직선운동으로 전환시키기 위한 구동돌기⒥5)가 일체로 마련된다. 구동돌기(65)는 후방으로 돌출 형성되어 선단부가 결합통(60)의 경사홈(61)에 헐겁게 결합됨으로써, 회전날개(58)(59)의 회존 시 경사홈(61)을 따라 상하로 이동하게 된다. 그리고, 이러힌 구동돌기(65)에는 경사홈(61)과의 마찰소음을 줄이기 위한 원통형상의 소음방지튜브(70)가 끼워져 설치되어 있다. 소음방지튜브(70)는 회전날개(58)(59)의 회전운동에 따라 경사홈(61) 내에서 용이하게 미끄러질 수 있도록 윤활수지재로 구성되어 있는데, 이것은 내열 내마모성이 우수한 테플론으로 구성하는 것이 바람직하다.In addition, as shown in Figure 4, the middle of the drive shaft 64 is fitted into the inclined groove 61 is coupled to convert the rotational movement of the rotary blades 58, 59 to the up and down linear movement of the drive shaft 64. The driving protrusion # 5 is provided integrally. The driving protrusion 65 is formed to protrude rearward so that the front end portion is loosely coupled to the inclined groove 61 of the coupling cylinder 60, thereby moving up and down along the inclined groove 61 when the rotary blades 58 and 59 are rotated. Done. The driving protrusion 65 is fitted with a cylindrical noise preventing tube 70 for reducing friction noise with the inclined groove 61. Noise prevention tube 70 is composed of a lubricating resin material so that it can easily slide in the inclined groove 61 according to the rotational movement of the rotary blades 58, 59, which is composed of Teflon excellent heat resistance wear resistance desirable.

다음에는 이와 같이 구성된 본 발명에 따른 냉기분산장치의 작동 및 효과를 설명한다.Next will be described the operation and effect of the cold air dispersing apparatus according to the present invention configured as described above.

먼저, 증발기(53) 상측에 배치된 팬(54)이 구동되면, 증발기(53)에서 생성된 냉기의 일부는 냉기토출구(56)를 통해 냉동실(51)로 인내되어 보관식품을 냉각시키며, 냉기의 나머지 일부는 덕트(55)를 통해 하측으로 내려와 냉장실(52)로 고르게 분산 공급된다.First, when the fan 54 disposed above the evaporator 53 is driven, a part of the cold air generated by the evaporator 53 is endured into the freezer compartment 51 through the cold air outlet 56 to cool the food stored therein. The remaining part of the lower portion is lowered through the duct 55 is distributed evenly supplied to the refrigerating chamber (52).

이 때, 냉상실(52)로 공급되는 냉기는 냉기분산장치를 통해 입체적으로 분산된다. 즉, 구동모터(66)의 구동으로 회전날개(58)(59)가 회전하면서 덕트(55)내로 유입된 냉기를 좌우측으로 분산 안내한다.At this time, the cold air supplied to the cold chamber 52 is three-dimensionally dispersed through the cold air dispersing apparatus. That is, the rotary blades 58 and 59 are rotated by the driving motor 66 to guide the cool air introduced into the duct 55 to the left and right.

또한, 회전날개(58)(59)의 회전운동과 동시에 경사홈(61)을 따라 구동돌기(65)가 이동되어 구동축(64)이 승하강한다. 이로 인해 상하분산날개(62)가 상하로 회동함으로써, 좌우로 분산되는 냉기의 일부는 또다시 상하로 분산되고, 이것에 의해 냉장실(52)에는 냉기가 상하, 좌우 입체적으로 분산 공급된다.In addition, the driving protrusion 65 is moved along the inclined groove 61 at the same time as the rotational movement of the rotary blades (58) and (59) to move up and down the drive shaft (64). As a result, the vertical dispersion blade 62 rotates up and down, so that a part of the cold air dispersed left and right is further dispersed up and down again, whereby cold air is distributed and supplied to the refrigerating chamber 52 vertically and horizontally.

한편, 구동축(64)의 승하강운동은 앞에서 설명한 바와 같이, 경사홈(61)을 따라 미끄림운동하는 구동돌기(65)에 의해 이루어지는데, 이러한 구동돌기(65)의 이동은 소음방지튜브(70)에 의해 보다 용이하게 이루어진다.On the other hand, the ascending and descending movement of the drive shaft 64 is made by a driving protrusion 65 sliding along the inclined groove 61, as described above, the movement of the driving protrusion 65 is a noise prevention tube ( 70) more easily.

즉, 실제로 구동돌기(65)에 끼워진 소음방지튜브(70)가 경시홈(61)에 직접 마찰하기 때문에, 이의 미끄럼운동이 보다 용이하게 이루어져 전반적인 마찰소음이 줄어들게 된다.That is, since the anti-noise tube 70 actually inserted into the driving protrusion 65 directly rubs against the slight groove 61, the sliding movement thereof becomes easier, so that the overall friction noise is reduced.

이상에서 상세히 설명한 바와 같이, 본 고안에 따른 냉장고의 냉기분산장치에 의하면, 회전날개 중도의 결합통에 마련된 경사홈을 따라 이동하여 상하분산날개를 상하방향으로 구동시키기 위한 구동축의 구동돌기에 윤활수지재의 소음방지튜브가 설치되어 있다. 따라서 경사홈을 따라 구동돌기가 보다 용이하게 미끄러져 냉기를 보다 안정적으로 분산 공급할 수 있으며, 작동소음이 보다 저감되어 제품신뢰성이 향상되는 이점이 있다.As described in detail above, according to the cold air dispersing apparatus of the refrigerator according to the present invention, the lubricant resin is driven to the driving projection of the drive shaft for driving the vertically distributed blades in the vertical direction by moving along the inclined grooves provided in the coupling cylinder of the rotary blades. Ash noise prevention tube is installed. Therefore, the driving protrusion slides more easily along the inclined groove, so that the cold air can be more stably distributed, and the operation noise is further reduced, thereby improving product reliability.
