A flap support member is formed on the front surface such that a rod-shaped shaft is formed in the transverse direction and a plurality of snap protrusions protruding along the cold air discharge direction are formed at a predetermined interval, and a snap protrusion of the flap support member is located in front of the flap support member. A flap is formed in which the insertion hole corresponding to the snap projection penetrates the upper end portion so that the penetrates the penetrating portion. Of a flap support member protrudes through the ball snap protrusions are snap-coupled to the coupling groove provides a non-return valve of the refrigerator cold air supply duct characterized by a flap departure avoidance side installed to prevent separation of said flaps.
이하, 첨부한 제2도를 참조하여 본 고안에 대하여 상세히 설명한다.Hereinafter, with reference to the accompanying Figure 2 will be described in detail the present invention.
도면에 도시되어 있는 바와 같이, 본 고안에 따른 냉장고 냉기공급덕트의 역류방지밸브는 먼저, 냉기공급덕트(10)의 말단부의 밸브설치벽(11)을 냉기 토출방향으로 연장 형성시킴과 동시에 상기 밸브설치벽(11) 내측에 냉기토출구(12a)를 갖는 플랩시이트(12)를 일체로 성형시키고 한편, 상기 밸브설치벽(11) 상단에는 요입홈(13)이 형성되어 있다.As shown in the figure, the non-return valve of the refrigerator cold air supply duct according to the present invention, first, while extending the valve installation wall 11 of the distal end of the cold air supply duct 10 in the cold air discharge direction, the valve A flap sheet 12 having a cold air outlet 12a is integrally formed inside the mounting wall 11, and a recessed groove 13 is formed at the upper end of the valve mounting wall 11.
그리고 중심부에는 봉형상의 축(14b)이 형성되어 있으며 상기 축(14b)의 양단부가 상기 요입홈(13)에 회전가능하게 삽입되고 상기 축(14b)의 하측 즉, 냉기토출 방향을 따라 일정간격 복수개의 스냅결합돌기(12b)가 형성된 플랩지지부재(14)가 형성되어 있다.A rod-shaped shaft 14b is formed at the center portion, and both ends of the shaft 14b are rotatably inserted into the recessed grooves 13, and a plurality of predetermined intervals are disposed below the shaft 14b along the cold air discharge direction. The flap support member 14 in which the two snap engagement protrusions 12b were formed is formed.
상기 플랩지지부재(14)의 전방에는 상기 플랩지지부재(14)의 스냅돌기(14a)가 관통하도록 스냅돌기(14a)에 대응하는 삽입공(15a)이 상단부에 형성된 플랩(15)이 설치된다.In front of the flap support member 14, a flap 15 having an insertion hole 15a corresponding to the snap protrusion 14a is provided at an upper end thereof so that the snap protrusion 14a of the flap support member 14 passes therethrough. .
상기 플랩(15)의 삽입공(15a)을 관통하여 돌출된 플랩지지부재(14)의 스냅돌기(14a)가 스냅결합홈(16a)에 결합되어 상기 플랩(15)의 이탈을 방지하는 플랩이탈방지편(16)이 설치된다.The flap detachment 14a of the flap support member 14 protruding through the insertion hole 15a of the flap 15 is coupled to the snap coupling groove 16a to prevent the flap 15 from being separated. The prevention piece 16 is provided.
따라서, 상기 플랩(15)의 상단부에 형성된 다수의 삽입공(15a)을 상기 플랩지지부재(14)의 스냅돌기(14b)에 삽입한 후 플랩이탈방지편(16)의 스냅결합홈에 결합시키고, 상기 플랩지지부재(14)의 중심에 고정된 축(14b)을 상기 밸브설치벽(12)의 요입홈(13)에 결합시키면 역류방지밸브가 완성된다.Therefore, the plurality of insertion holes 15a formed at the upper end of the flap 15 are inserted into the snap protrusion 14b of the flap support member 14, and then coupled to the snap coupling groove of the flap detachment preventing piece 16. When the shaft 14b fixed to the center of the flap support member 14 is coupled to the inlet groove 13 of the valve mounting wall 12, the check valve is completed.
이상의 설명과 같은 구성에 의하면 역류방지밸브는 냉기공급덕트의 밸브설치벽을 냉기 토출방향으로 연장 형성함과 아울러 상기 밸브설치벽 내측에 냉기토출구를 갖는 플랩시이트를 일체로 성형함으로써 부품관리가 용이하다.According to the configuration as described above, the non-return valve is easy to manage parts by extending the valve installation wall of the cold air supply duct in the cold air discharge direction and integrally forming a flap sheet having a cold air outlet inside the valve installation wall. .
또한, 플랩시이트의 전면에 플랩을 간단하게 설치할 수 있다.Moreover, a flap can be easily installed in the front surface of a flap sheet.
