본 고안은 각종 전기제품의 도어 개폐장치에 관한 것으로 특히, 도어를 개폐시키는데 있어 충격을 완화시켜 개폐동작이 원활하게 이루어지도록 되 전기제품의 도어 개폐장치에 관한 것이다.The present invention relates to a door opening and closing device of various electrical appliances, and more particularly, to reduce the impact of opening and closing the door to smoothly open and close the operation of the door opening and closing device of the electrical appliance.
종래의 경우 각종 전기제품(예. 오븐렌지등)의 도어 개폐장치는 일반적으로 도면 제3도에 도시된 바와같이 제품의 본체(80)에 측부재(82)를 매개로 도어(70)를 장착한후 고정부재(81)로 체결시킨 구조이므로 도어개폐시, 도어(70)의 혹은 폐동작이 완료될때까지 사용자가 도어(70)를 잡고 있어야만 제품의 파손을 방지할 수 있었으나, 사용자의 부주의로 도어(70)를 닫을때, 무리한 힘을 가하거나, 도어(70)를 놓칠경우에는 충격에 의해 제품이 파손되는 등 사용상에 여러 결점이 있었다.In the conventional case, the door opening and closing device of various electric appliances (eg, an oven, etc.) is generally equipped with the door 70 via the side member 82 to the main body 80 of the product, as shown in FIG. Since the structure is fastened by the fixing member 81, when the door is opened or closed, the user must hold the door 70 until the door 70 or the closing operation is completed, thereby preventing damage to the product. When closing the door 70, if excessive force is applied, or if the door 70 is missing, there are various defects in use, such as damage to the product by the impact.
따라서 본 고안은 상기와 같은 종래의 결점을 해소시키기 위해 전기 제품의 도어개폐구조로 캠과 탄성부재를 이용하여 개폐시 발생될 수 있는 충격을 완화시킬수 있도록 안출된 것으로 첨부된 도면에 의하여 그 구성과 작용효과를 상세히 설명하면 다음과 같다.Therefore, the present invention is designed to mitigate the shock that may occur during opening and closing by using the cam and the elastic member as the door opening and closing structure of the electrical appliance to solve the conventional drawbacks as described above and the configuration and according to the accompanying drawings Detailed description of the effect is as follows.
전기제품의 도어 개폐장치에 있어서, 사각축(1)상에 보조판(2) 안내면(3a)을 갖는 고정캠(3), 상기 안내면(3a)에 슬라이딩되는 미끄럼면(4a) 및 걸림돌부(4b)를 갖는 작동캠(4), 탄성부재(5)를 순차적으로 삽입시킨 상태에서 미끄럼폄(4a′) 걸림돌부(4b′)를 갖는 작동캠(4′), 안내면(3a′)를 갖는 고정캠(3)을 삽입시켜, 고정부재(6)를 상기 사각축(1)일측에 고정시켜서된 조립체를 도어 (7)의 걸리턱(7b)를 갖는 삽입홈(7a)에 끼워준후 상기 고정캠(4′)을 매개로 본체(8)의 지지부재(9)에 도어(7)를 장착시킨 구성으로, 도어(7) 개폐시 작동캠(4)(4′)이 좌, 우 이동되면서 탄성부재(5)를 팽창 혹은 수축시키면서 충격을 완화시킬 수 있도록 구성된 것이다.In the door opening and closing device of an electric product, a fixed cam (3) having a guide plate (2) guide surface (3a) on the square shaft (1), a sliding surface (4a) and a locking portion (4b) sliding on the guide surface (3a) (4a) having a sliding member (4a ') and an engaging cam (4b'), and a fixing surface (3a '). Insert the cam (3), the fixing member 6 is fixed to one side of the square shaft (1) to fit the assembly into the insertion groove (7a) having a hooking jaw (7b) of the door 7 and then the fixing cam The door 7 is mounted on the support member 9 of the main body 8 via the 4 ', and when the door 7 is opened and closed, the actuating cams 4 and 4' move left and right. It is configured to mitigate the impact while expanding or contracting the member (5).
이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
도면에 도시된 바와같이 본 고안은 제품의 본체(8)에 고정캠(3)(3′), 작동캠(4)(4′)및 탄성부재(5), 보조판(2)이 사각축(1)에 삽입되어 고정부재(6)로 구성되어진 조립체를 매개로 도어(7)를 장착시켜, 도어(7)개폐시 작동캠(4)(4′)의 미끄럼면(4a)(4a′)이 고정캠(3)(3′)의 안내면(3a)(3a′)를 따라 슬라이딩되면서 탄성부재(5)를 팽창 혹은 수축시켜줌에 따라 도어(7)개폐시 발생되는 충격을 완화시킬 수 있도록 된 것이다. 즉, 사용자가 닫혀있는 도어(7)를 개방시키게되면 도어(7)의 삽입홈(7b)에 형성된 걸림턱(7a)에 걸림돌부(4b)(4b′)가 밀착되게 걸림되면서 내설된 작동캠(4)(4′)의 미끄러면(4a)(4a′)이 도어(7)의 개방동작에 의해 본체(8)의 지지부재(9)에 고정된 고정캠(3′) 및 보조판(2)이 밀착된 고정캠(3)의 안내면(3a)(3a′)을 따라 화살표 R 방향(도면 제2도 (나)에 표시됨)으로 이동되면서 안내면(3a)(3a′)과 미끄럼면(4a)(4a′)이 도면 제2도 (가)와 같이 맞물림된 상태가 되는데, 이때, 수축된 상태의 탄성부재(5)는 자체 복원력에 의해 팽창되므로 도어(7)는 원활하게 개방되어진다.As shown in the drawings, the subject innovation of the present invention is the fixed cam (3) (3 '), the actuating cam (4) (4') and the elastic member (5), the auxiliary plate (2) is a square shaft ( 1) by mounting the door (7) through the assembly composed of the fixing member (6) inserted into the door (7), the sliding surface (4a) (4a ') of the operating cam (4) (4') when opening and closing the door (7) Sliding along the guide surfaces (3a) and (3a ') of the fixed cam (3) (3') to expand or contract the elastic member (5) to mitigate the impact generated when opening and closing the door (7) will be. That is, when the user opens the closed door (7), the operation cam installed as the locking projection (4b) (4b ') is in close contact with the locking jaw (7a) formed in the insertion groove (7b) of the door (7) (4) The fixed cam 3 'and the auxiliary plate 2, on which the sliding surfaces 4a and 4a' of the 4 'are fixed to the supporting member 9 of the main body 8 by the opening operation of the door 7; ) Is moved along the guide surface 3a (3a ') of the fixed cam 3 in close contact with the arrow R direction (indicated in Fig. 2 (b) of the drawing), and the guide surface 3a (3a') and the sliding surface 4a. 4a 'is in the engaged state as shown in FIG. 2A, in which the retracted elastic member 5 is expanded by its restoring force, so that the door 7 is smoothly opened.
또한, 상기와 같이 개방되는 과정에서 작동캠(4)(4′)의 미끄럼면(4a)(4a′)과 고정캠(3)(3′)의 안내면(3a)(3a′)이 상호 치합되는 관계로 도어(7)가 일정각도 이상으로 개방되는 것을 방지할 수 있다.In addition, the sliding surface 4a (4a ') of the operation cam (4) (4') and the guide surface (3a) (3a ') of the fixed cam (3) (3') are engaged with each other during the opening process as described above. As a result, the door 7 may be prevented from opening at a predetermined angle or more.
한편, 사용자가 제품에 먼지등 이물질 혼입을 방지하도록 도어(7)를 닫아주게되면, 작동캠(4)(4′)의 미끄럼폄(4a)(4a′)은 고정캠(3)(3′)의 안내면(3a)(3a′)을 따라 화살표 L방향(도면 제2도 (가)에 표시됨)으로 이동되면서, 안내면(3a)(3a′)과 미끄럼면(4a)(4a′)이 도면 제2도 (나)와 같이 이완된 상태가 되는데, 이때 팽창된 상태의 탄성부재(5)는 도면 제2도 (나)와 같이 수축되므로, 도어(7)는 자중에 의해서 원활하게(부드럽게)하향이동하면서 닫혀진다.On the other hand, when the user closes the door 7 so as to prevent foreign matters from entering into the product, the sliding cams 4a and 4a of the operating cams 4 and 4 'are fixed to the fixed cams 3 and 3'. The guide surface 3a (3a ') and the sliding surface 4a (4a') are moved along the guide surface 3a (3a ') in the arrow L direction (shown in FIG. As shown in FIG. 2 (b), the elastic member 5 in the expanded state is contracted as shown in FIG. 2 (b), so that the door 7 smoothly (smooth) by its own weight. It is closed while moving downward.
이상에서 본 바와같이 본 고안은 제품내부로 먼지등 이물질의 혼입을 방지하기 위해서 장착되는 도어(7)에 고정캠(3)(3′), 작동캠(4)(4′) 및 탄성부재(5), 보조판(2), 사각축(1)으로된 조립체를 도어(7)의 삽입홈(7a)에 밀착 적용하여 도어(7)를 개폐시킴에 따라 작동캠(4)(4′)의 미끄러면(4a)(4a′)이 고정캠(3)(3′)의 안내면(3a)(3a′)을 따라 슬라이딩되면서 탄성부재(5)를 팽창 혹은 수축시켜주므로 도어 개폐시 발생되는 충격을 완화시킬 수 있을뿐 아니라, 개폐동작이 원활하므로, 사용이 편리함을 물론 고정발생율을 저하시키는 등 제품의 신뢰도를 향상시킬 수 있는 장점이 있다.As described above, the present invention is a fixed cam (3) (3 '), the operating cam (4) (4') and the elastic member (7) in the door (7), which is mounted to prevent the mixing of foreign substances such as dust into the product. 5) by applying the assembly of the auxiliary plate (2), the square shaft (1) in close contact with the insertion groove (7a) of the door (7) to open and close the door (7) of the operating cam (4) (4 ') As the sliding surfaces 4a and 4a 'slide along the guide surfaces 3a and 3a' of the fixed cams 3 and 3 ', the elastic members 5 expand or contract, thereby preventing shocks from occurring when the door is opened or closed. In addition to mitigating, the opening and closing operation is smooth, there is an advantage that can improve the reliability of the product, such as ease of use as well as lowering the fixed occurrence rate.
