And to improve the lever structure so that the cold air flow can be smoothly controlled.

일반적으로, 냉장고는 증발기에서 냉매가 주변 대기의 잠열을 빼앗아 증발함에 따라 주변 공기를 냉각시키게 되고, 이렇게 냉각된 냉기를 도 1에 개략적으로 도시된 바와같이 송풍팬(1)에 의해 덕트(2)를 통하여 냉동실과 냉장실로 공급하게 된다.In general, the refrigerator cools the surrounding air as the refrigerant evaporates the latent heat of the surrounding atmosphere from the evaporator, and the cooled air is cooled by the blower fan 1 as illustrated in FIG. Through the freezer and the refrigerating chamber is supplied.

이를 위하여 냉장고 냉동실(3)에서 하측의 냉장실(4)로 냉기를 공급하기 위하여 덕트(2)가 형성되며, 상기 덕트에는 필요에 따라 냉장실의 온도를 제어할 수 있게 냉동실로부터 냉장실로의 냉기 공급량을 제어하기 위하여 덕트를 적어도 부분적으로 개폐할 수 있도록 조절 레버(5)가 설치된다. 이러한 냉기 공급량 조절 레버는 회전식 또는 슬라이드식으로 구성될 수 있으며, 본 발명에서는 슬라이드식의 종래 레버 구조의 개선에 관한 것이다.To this end, a duct (2) is formed to supply cold air from the refrigerator freezer compartment (3) to the lower refrigerating compartment (4). The duct is provided with a supply amount of cold air from the freezer compartment to the refrigerating compartment to control the temperature of the refrigerating compartment as necessary. An adjusting lever 5 is provided to at least partially open and close the duct for control. The cold air supply amount adjusting lever may be configured to be rotatable or slide type, and the present invention relates to an improvement of the conventional lever structure of the slide type.

종래의 레버 구조는 도 2 내지 도 4에 개략적으로 부분단면도로 도시된 바와같이, 레버 하측의 덕트(2)내에 배치되는 차단부재(6)가 판상으로 이루어져 있으며, 송풍팬에 의해 송풍된 냉기가 냉장실로 유동하지 못하도록 덕트를 완전히 폐쇄 하는 위치와, 도 3에 도시된 바와같이 부분적으로 덕트를 폐쇄하고 일부는 개방되게 하는 위치, 및 도 4에 도시된 바와같이 레버의 차단부재(6)가 덕트에서 완전히 벗어나 덕트의 유로가 완전히 개방되는 위치로 슬라이드가능하게 배치된다.In the conventional lever structure, as shown in a partial cross-sectional view schematically in FIGS. 2 to 4, the blocking member 6 disposed in the duct 2 under the lever has a plate shape, and the cold air blown by the blower fan is The position of closing the duct completely to prevent flow into the refrigerating compartment, the position of partially closing the duct as shown in FIG. 3 and allowing some to be opened, and the blocking member 6 of the lever as shown in FIG. And is slidably disposed in a position where the flow path of the duct is completely out of position.

이러한 종래 조절 레버의 구조에 따라 도 3에 도시된 부분적으로 덕트의 유로를 폐쇄하여 일부의 냉기만 냉장실로 공급되게 하는 위치에서는 판상의 차단부재 뒤쪽에서 냉기가 와류를 형성하게 되어 냉기 흐름을 방해하게 되고, 그에 따라 소음에 발생되는 문제가 있었다. According to the structure of the conventional control lever in the position shown in Figure 3 to close the flow path of the duct to only a portion of the cold air to the refrigeration chamber, the cold air behind the blocking member to form a vortex to hinder the flow of cold air Thereby, there was a problem caused by noise.

따라서, 본 발명의 목적은 종래 냉장고의 냉기 공급량 조절을 위하여 덕트에 제공되는 조절 레버의 차단부재 뒤쪽에서의 냉기 와류 형성 및 소음발생의 문제를 해소하여 소음이 유발되지 않고 냉기 흐름을 방해하지 않도록 개선된 구조의 차단부재를 갖는 냉장고용 냉기 공급량 조절 레버를 제공하는 것이다.Accordingly, an object of the present invention is to solve the problem of the formation of cold air vortex and noise generated in the rear of the blocking member of the control lever provided in the duct for controlling the supply of cold air in the conventional refrigerator to improve noise so as not to disturb the flow of cold air It is to provide a cold air supply amount control lever for a refrigerator having a blocking member of the structure.

상기한 목적을 달성하기 위한 본 발명의 냉장고 냉기 공급량 조절 레버는 하측에 차단부재를 갖고 냉동실로부터 냉장실로 냉기 공급을 위한 덕트속에서 냉기 공급을 완전히 차단하도록 덕트를 폐쇄하는 위치와, 덕트를 부분적으로 개방하는 위치 및 덕트를 완전히 개방하여 냉동실로부터의 냉기가 냉장실로 원활하게 공급되게 하는 위치 사이에서 이동가능하게 배치되는 냉장고용 냉기 공급량 조절 레버에 있어서, 상기 차단부재는 냉기 흐름 방향의 앞쪽면과 뒤쪽면에서 냉기 흐름이 원활하게 유동하도록 횡단면이 타원 형상의 윤곽을 갖고 돌출되게 형성된 것을 특징으 로 하여 구성된다. Refrigerator air supply amount adjustment lever of the present invention for achieving the above object has a blocking member on the lower side and the position to close the duct to completely block the cold air supply in the duct for supply of cold air from the freezer compartment to the cold compartment, and partially A cold air supply amount control lever for a refrigerator, which is movably disposed between an open position and a position in which the duct is fully opened to allow the cool air from the freezer to be smoothly supplied to the refrigerating compartment, wherein the blocking member is provided at the front and rear sides of the cold air flow direction. It is characterized in that the cross section is formed to protrude with an elliptic contour so that the cold air flow smoothly in the plane.

이하, 본 발명의 실시예를 도시한 첨부 도면을 참고하여 본 발명을 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings showing an embodiment of the present invention will be described in detail the present invention.

도 5에는 본 발명에 따라 개선된 구조의 차단부재(11)를 갖는 냉기 공급량 조절 레버(10)가 도시되어 있다. 본 발명에 따라, 냉기 공급량 조절 레버(10)의 하측에서 하방으로 돌출되게 형성되어 냉기 공급용 덕트속에 배치되는 차단부재(11)는 그 횡단면 형상이 도 6에 도시된 바와같이 타원 형상의 윤곽을 갖고 돌출되어 있으며, 상기 차단부재의 중앙부에는 보강용 리브(12)가 형성되어 있다.5 shows a cold air supply amount adjusting lever 10 having a blocking member 11 of an improved structure according to the present invention. According to the present invention, the blocking member 11 formed to protrude downward from the lower side of the cold air supply control lever 10 and disposed in the cold air supply duct has an elliptical contour as shown in FIG. 6. And protrude, and a reinforcing rib 12 is formed at the center of the blocking member.

상기한 바와같이 조절 레버(10)에 형성되는 차단부재(11)에 의해 냉기 공급용 덕트(도 1 참조)속에 배치될 때 레버에 의해 사용자가 설정하는 위치에 따라 도 7에 도시된 위치에서와 같이 냉동실로부터 냉장실로의 냉기 공급량을 완전히 막도록 덕트(15)를 완전히 폐쇄하거나, 도 8에 도시된 바와같이 적어도 일부만 덕트를 개방하여 덕트를 통한 냉기 공급이 제한적으로 허용하도록 하거나, 도 9와 같이 덕트(150를 완전히 개방하여 냉동실에서의 냉기가 원활하게 냉장실로 공급되게 하여 냉장실의 온도를 보다 낮게 조절할 수 있게 위치 조절된다.In the position shown in FIG. 7 according to the position set by the user by the lever when disposed in the cold air supply duct (see FIG. 1) by the blocking member 11 formed in the adjustment lever 10 as described above. As shown in FIG. 8, the duct 15 is completely closed to completely prevent the supply of cold air from the freezer compartment to the refrigerating compartment, or at least a part of the duct 15 is opened to restrict the supply of cold air through the duct. The duct 150 is completely opened to allow the cool air in the freezer compartment to be smoothly supplied to the refrigerating compartment so that the temperature of the refrigerating compartment can be adjusted lower.

본 발명에 따라 냉기 조절 레버의 차단부재(11)가 타원 형상의 윤곽을 가짐으로써, 도 8에 도시된 바와같이 덕트(15)속에서 부분적으로 돌출되게 위치하여 냉기의 흐름을 제한하게 되는 경우에, 냉기 흐름이 차단부재의 타원형의 표면을 따라 유동하게 되므로, 냉기 흐름이 차단부재의 앞쪽면(16)에 의해 받게 되는 저항이 감소됨에 따라 소음 발생 또한 감소된다. 또한, 냉기 흐름은 차단부재의 곡면상의 앞 쪽면으로 부터 뒤쪽면(17)으로 원활하게 유동하게 되므로 뒤쪽면이 끝나는 지점에서의 와류 발생이 최소화되므로 냉기 흐름이 원활하게 이루어지므로 사용자가 레버로 설정하는 냉장실의 설정 온도 제어가 정확하게 달성될 수 있게 되므로 종래 냉장고에서의 단순한 판상으로 된 차단부재 뒤쪽면에서의 와류 발생으로 인한 냉기 흐름이 원활하지 못하여 냉장실의 설정 온도가 정확히 달성되지 못함에 따른 제품 신뢰도 저하의 문제가 간편하게 해소될 수 있다.When the blocking member 11 of the cold air control lever has an elliptic contour according to the present invention, as shown in FIG. 8, the block member 11 is partially protruded in the duct 15 to limit the flow of cold air. Since the cold air flows along the oval surface of the blocking member, noise generation is also reduced as the cold air flow is reduced by the resistance of the front face 16 of the blocking member. In addition, since the cold air flows smoothly from the front surface on the curved surface of the blocking member to the rear surface 17, since the occurrence of vortex at the end of the rear surface is minimized, the cold air flow is made smoothly so that the user sets the lever. Since the set temperature control of the refrigerating compartment can be accurately achieved, the cold air flow due to the vortex generation at the back of the simple plate-shaped blocking member in the conventional refrigerator is not smooth, and thus the reliability of the product due to the inaccurate setting temperature of the refrigerating compartment is not accurately achieved. Can be easily solved.

본 발명에 따라, 냉장고의 냉동실로부터 냉장실로 송풍팬에 의해 냉기를 냉기 덕트를 통하여 공급하도록 되고, 그 덕트에 제공되어 냉장실로의 냉기 공급량을 제어하도록 제공되는 조절 레버의 하측에 돌출되게 형성되며 덕트속에 배치되는 차단부재를 타원형의 곡면을 갖도록 함으로써, 냉기 흐름과 부딪히는 앞쪽면(16)에서의 소음 발생을 감소시키고, 뒤쪽면에서도 냉기 흐름이 원활하게 유지되어 와류가 발생되지 않고 냉기 흐름이 원활하게 이루어지게 되므로 조절 레버에 의한 냉장실의 온도 설정이 정확하게 달성될 수 있게 되어 제품의 신뢰도가 향상되며, 기존의 냉기 덕트의 구조를 변경하지 않고도 간편하게 장착할 수 있는 장점이 있다.According to the invention, the cold air from the freezer compartment of the refrigerator to the refrigerating chamber by the blowing fan is supplied to the cold air through the duct, is formed to protrude to the lower side of the control lever provided in the duct to control the amount of cold air supplied to the refrigerating chamber By having an elliptical curved surface of the blocking member disposed therein, the noise generated in the front surface 16 that collides with the cold air flow is reduced, and the cold air flow is smoothly maintained at the rear surface, so that the cold air flow is smoothly generated without vortex flow. Since the temperature setting of the refrigerating chamber by the adjustment lever can be accurately achieved, the reliability of the product is improved, and there is an advantage that it can be easily installed without changing the structure of the existing cold air duct.
