본 고안은 냉장고의 멀티덕트에 관한 것으로, 보다 상세하게는 조립작업 및 기밀유지가 용이하도록 멀티덕트를 내상의 내측에 설치하도록 한 냉장고의 멀티덕트에 관한 것이다.The present invention relates to a multi-duct of the refrigerator, and more particularly to a multi-duct of the refrigerator to install the multi-duct inside the inner box to facilitate assembly work and airtight.

일반적으로 냉장실 후벽의 상부에는 냉각기실에 의해 생성된 냉기를 냉장실로 선택적으로 공급하여 주는 댐퍼가 설치되고 상기 댐퍼의 하측으로는 멀티덕트가 연통설치되어 상기 댐퍼를 통해 냉장실로 공급된 냉기를 냉장실의 상부, 중앙, 하부로 골고루 토출시키게 된다.In general, a damper for selectively supplying the cool air generated by the cooler chamber to the refrigerating chamber is installed at the upper part of the rear wall of the refrigerating chamber, and a multi duct is installed at the lower side of the damper to supply the cold air supplied to the refrigerating chamber through the damper. It is evenly discharged to the top, center, and bottom.

종래의 멀티덕트는 제1도에 도시되어 있는 바와 같이, 그 내측으로 절연재(2)가 내장되어 'U'자형으로 형성된 ABS재질의 루버(1)를 냉장실 후면부의 내상(3)에 나사(4)결합하도록 하는 것이 일반적이었다.As shown in FIG. 1, the conventional multi duct has an ABS material louver 1 formed in a 'U' shape with an insulating material 2 embedded therein, and screwed into the inner box 3 of the rear side of the refrigerating compartment. It was common to have a bond.

그러나, 이와 같은 구성에 따르면 상기 루버(1)와 내상(3)사이의 볼트고정부위에서 발생되는 틈새의 기밀유지가 곤란하고, 또한 그 재료인 ABS의 가격이 고가여서 제작비용이 상승하게되는 단점이 있다.However, according to such a configuration, it is difficult to maintain the airtightness of the gap generated on the bolt fixing part between the louver 1 and the inner box 3, and also the manufacturing cost increases due to the high price of ABS as the material. There is this.

따라서, 본 고안의 목적은 부품비를 절감시킬 수 있고, 또한 조립작업 및 기밀유지가 용이한 냉장고의 멀티덕트를 제공하는 것이다.Accordingly, an object of the present invention is to provide a multi-duct of the refrigerator that can reduce the parts cost, and also easy assembly work and airtight.

위와 같은 목적을 달성하기 위해 본 고안에서는, 후면 중앙부에 냉장실 내측방향으로 'U'자형으로 돌출부가 형성되고 상기 돌출부 전면에 상하로 다수개의 통공이 형성된 냉장실의 내상과, 전면에 상기 내상의 통공과 일치되어 연통하는 다수의 통공이 형성되고 후면은 상기 내상 외측에 형성된 단열 발포층에 일정깊이만큼 삽입되면서 상기 돌출부의 내측으로 대응되어 삽입고정되는 관형상의 절연재와, 상기 절연재의 후면과 상기 단열발포층사이에 개재되는 카버를 포함하는 것을 특징으로 하는 냉장고의 멀티덕트를 제공한다.In order to achieve the above object, in the present invention, the inner portion of the refrigerating chamber formed with a plurality of through-holes formed on the front surface of the refrigerator in the direction of the 'U' shape in the refrigerating chamber inward direction, and the front and the through-holes on the inner surface of the refrigerating chamber. A plurality of through-holes are formed in communication with each other, and the rear surface is inserted into the thermal insulation foam layer formed on the outer side of the inner shell with a predetermined depth and is inserted into and fixed to the inner side of the protrusion, and the rear surface of the insulation and the thermal insulation foam It provides a multi-duct of the refrigerator comprising a coverr interposed between the layers.

이하, 첨부한 제2도를 참고하여 본 고안의 일 실시예에 대하여 상세히 설명한다.Hereinafter, with reference to the accompanying Figure 2 will be described in detail an embodiment of the present invention.

제2도에 도시되어 있는 바와 같이, 본 고안의 일 실시예에 따른 냉장고의 멀티덕트는 단면이 'U'자형으로 돌출부(35)가 형성되고, 그 전면부에 다수개의 통공(30a)을 구비하는 냉장고의 냉장실 내상(30)을 포함한다.As shown in FIG. 2, the multi duct of the refrigerator according to the exemplary embodiment of the present invention has a protruding portion 35 formed in a 'U' shape in cross section, and has a plurality of through holes 30a in the front surface thereof. It includes the refrigerator compartment inner box 30 of the refrigerator.

상기 돌출부(35)의 내측으로는 상기 돌출부(35)의 형상에 대응되도록 사각형의 단면을 갖는 사각관형상의 절연재(20)가 연직방향으로 삽입설치된다.Inside the protruding portion 35, a rectangular tubular insulating material 20 having a rectangular cross section is inserted in the vertical direction so as to correspond to the shape of the protruding portion 35.

상기 관형상의 절연재(20)의 전면으로는 상기 내상(30)에 형성된 다수의 통공(30a)설치위치와 일치되어 상호 연통되는 다수의 통공(20a) 이 구비되어 있으므로 댐퍼(미도시)를 통해 공급된 냉기는 상기 절연재(20)에 형성된 통공(20a)및 내상(30)에 형성된 통공(30a)을 경유하여 냉장고 냉장실 내로 유입될 수 있다.The front of the tubular insulating material 20 is provided with a plurality of through holes (20a) are in communication with each other in accordance with the installation position of the plurality of through holes (30a) formed in the inner wound (30) through a damper (not shown) The supplied cold air may be introduced into the refrigerator refrigerating chamber via the through hole 20a formed in the insulating material 20 and the through hole 30a formed in the inner box 30.

또한, 상기 관형상의 절연재(20)의 후방에는 이 절연재(20)를 상기 돌출부(35)에 긴밀하게 밀착시키고, 또한 이 절연재(20)를 보호하기 위한 카버(10)가 씌워진다.In addition, the back cover of the tubular insulator 20 is covered with the cover 10 for closely contacting the insulator 20 to the protruding portion 35 and for protecting the insulator 20.

상기 카버(10)는 그 양단부를 접착테이프(50)를 이용하여 상기 내상(30)의 배면에 부착시킴으로써 고정될 수 있다.The carver 10 may be fixed by attaching both ends thereof to the rear surface of the inner phase 30 using the adhesive tape 50.

상기 카버(10)의 후측으로는 냉장고의 본체 캐비넷과 내상 사이에 충진되는 단열발포층(40)이 형성된다.On the rear side of the carver 10 is formed a heat insulation foam layer 40 is filled between the main cabinet and the inner phase of the refrigerator.

위와 같은 구성의 본 고안의 일 실시예에 따른 냉장고의 멀티덕트에 의하면, 내상(10)과 절연재(20)의 결합면에 틈새가 존재하지 않으므로 냉장실 후면부 내상(10)에 설치되는 멀티덕트(100)의 기밀유지가 용이하고, 또한 냉기덕트를 내상의 배면에 설치하므로 재료비가 고가인 ABS재질 대신 폴리프로필렌재를 사용하여 멀티덕트의 절연재(20)를 형성할 수 있으므로 재료비가 절감되는 효과를 얻을 수 있다.According to the multi-duct of the refrigerator according to an embodiment of the present invention of the configuration as described above, since there is no gap in the coupling surface of the inner wound 10 and the insulating material 20, the multi-duct (100) installed in the inner wound 10 of the refrigerating compartment. Airtightness and easy installation of the cold air duct on the back of the inner box, so the polypropylene material can be formed using polypropylene material instead of ABS material, which is expensive. Can be.

이상은 본 고안의 일 실시예에 대한 설명이며, 본 고안은 그 요지 구성의 범위 내에서 다양한 변경이 가능하다.The above is a description of an embodiment of the present invention, and the present invention is capable of various modifications within the scope of the gist configuration.
