본 발명은 전기밥솥의 뚜껑 개폐장치에 관한 것으로 특히 뚜껑이 열릴때 부드럽게 열릴 수 있도록 한 것이다.The present invention relates to a lid opening and closing device of the electric rice cooker to be able to open particularly smoothly when the lid is opened.

종래의 전기밥솥의 뚜껑 개폐장치는 제1도 및 제2도와 같이 뚜껑(1)에 형성된 돌부(2)와, 상기 돌부(2)를 본체(3)에 연결하여 뚜껑(1)이 개폐될 수 있도록 축(4)과 상기 축(4)을 중심으로 하여 뚜껑(1)이 열리도록 탄력을 가해주는 탄성부재(5)와, 상기 뚜껑(1)이 탄성부재(5)에 의하여 축(4)을 중심으로 하여 열릴 때 회전력을 약화시켜 줄 수 있도록 돌부(2)의 선단이 닿도록 한 롤러(6)와, 상기 롤러(6)가 회전되도록 축설된 축(7)으로 구성되었다.Lid opening and closing device of a conventional electric rice cooker can be opened and closed the lid (1) by connecting the protrusion (2) formed on the lid (1) and the main body (3), as shown in FIG. An elastic member 5 for applying elasticity to open the lid 1 around the shaft 4 and the shaft 4 so that the lid 1 is connected to the shaft 4 by the elastic member 5. It consists of a roller (6) so that the tip of the protrusion (2) to reach when opened about the center and the shaft (7) arranged so that the roller (6) rotates.

그리고 보턴(8)은 뚜껑(1)을 개폐시켜주는 것이다.And the button 8 is to open and close the lid (1).

이와같이 구성된 상태에서 닫혀진 뚜껑(1)을 열고저 할때는 보턴(8)을 눌러주게 되면 걸쇠가 풀리면서 탄성부재(5)의 탄력에 의하여 축(4)을 중심으로 하여 뚜껑(1)이 열리게 된다.When opening the closed cap (1) in the state configured in this way, when pressing the button (8), the latch is released and the lid (1) is opened around the shaft (4) by the elasticity of the elastic member (5).

이와같이 뚜껑(1)이 열리게 되면 뚜껑(1)에 형성된 돌부(2)의 선단이 축(7)에 축설된 롤러(6)에 닫기 때문에 롤러(6)가 눌리면서 같이 회전하기 때문에 롤러(6)가 뚜껑(1)의 회전력을 약화시켜 부드럽게 열리는 것이었다.When the lid 1 is opened in this way, the tip of the protrusion 2 formed on the lid 1 is closed by the roller 6 arranged on the shaft 7, so that the roller 6 rotates together while the roller 6 is pressed. The rotational force of the lid 1 was weakened and opened smoothly.

그러나, 뚜껑을 제작시 뚜껑에 형성된 돌부에 축이 축설되도록 끼워 넣어야 하기 때문에 작업성이 좋지않고, 롤러가 돌기에 눌리면서 회전하기 때문에 롤러가 쉽게 마모되어 자주 교환해야 하는 문제가 있을뿐만 아니라 돌부가 외관으로 돌출되기 때문에 미관상에도 문제점이 있었다.However, when the lid is manufactured, the workability is not good because the shaft must be inserted into the protrusion formed on the lid, and because the roller is rotated while being pressed on the protrusion, the roller is easily worn and there is a problem that frequently needs to be replaced. There was a problem in appearance because it protrudes.

본 발명은 이러한 점을 감안하여 발명한 것으로서, 뚜껑에 축설된 힌치축이 몸체에 연결되어 회동할 수 있도록 연결하는 힌지기둥과 삽입홈을 구성하고, 상기 힌지기등과 삽입홈이 결합된 상태에서 탄성부재의 탄력에 의하여 뚜껑이 열릴때 과도한 세기로 빨리 열리는 것을 마찰에 의하여 부드럽게 열리도록 하는 마찰수단을 구비함으로써 뚜껑이 열릴 때 부드럽게 열리도록 하는데 목적이 있다.The present invention has been invented in view of this point, and the hinge shaft arranged on the lid is configured to connect the hinge pillar and the insertion groove to be connected to the body, in the state the hinge and the insertion groove is coupled The object of the present invention is to provide a smooth opening when the lid is opened by providing friction means for opening the lid quickly by excessive force when the lid is opened by elasticity of the elastic member.

본 발명 전기밥솥의 뚜껑 개폐장치를 제3도 내지 제6도에 의하여 설명한다.The lid opening and closing device of the rice cooker of the present invention will be described with reference to FIGS.

뚜껑(101)이 축설된 힌지축(102)이 몸체(103)에 연결되어 회동할 수 있도록 몸체(103)에 형성된 힌지기둥(105)과, 상기 힌지기둥(105)에는 뚜껑(101)에 축설된 힌지축(102)이 삽입되어 회전될 수 있도록 형성된 삽입홈(106)과, 상기 힌지축(102)이 삽입홈(106)에 결합된 상태에서 탄성부재 (104)의 탄력에 의하여 뚜껑(101)이 열릴 때 과도한 세기로 빨리 열리는 것을 탄성의 변위에 의해 부드럽게 열리도록 하는 마찰수단을 구비하였다.A hinge pillar 105 formed on the body 103 so that the hinge shaft 102 on which the lid 101 is arranged is connected to the body 103 to be rotated, and on the hinge pillar 105, the hinge shaft 102 is disposed on the lid 101. The insertion groove 106 is formed so that the hinge shaft 102 is inserted and rotated, and the lid 101 by the elasticity of the elastic member 104 in a state in which the hinge shaft 102 is coupled to the insertion groove 106. It was provided with a friction means to open quickly with excessive strength when the) was opened.

상기 탄성부재(1049는 힌지축(102)에 축설되게 하여 일단은 몸체(103)에 지지되며, 타단은 뚜겅(101)내에 고정토록 하였다.The elastic member 1049 is arranged on the hinge shaft 102 so that one end is supported by the body 103 and the other end is fixed in the lid 101.

그리고, 뚜껑(101)이 열릴 때 뚜껑 (101)의 측단부(101′)가 닿지 아니하도록 탄성부재 (104)에 경사면(104′)을 구비하였다.And the inclined surface 104 'was provided in the elastic member 104 so that the side end part 101' of the lid 101 may not touch when the lid 101 is opened.

마찰수단은 뚜껑 (101)에 고정된 탄성편(107)과, 상기 뚜껑 (101)이 열릴때 탄성편(107)이 닿아 탄성편(107)이 변위를 일으키도록 몸체 (103)에 형성된 힌지기둥(105)에 마찰면(105′)을 구비하였다.The friction means includes an elastic piece 107 fixed to the lid 101 and a hinge column formed on the body 103 such that the elastic piece 107 is in contact with the elastic piece 107 when the lid 101 is opened to cause displacement. The friction surface 105 'was provided in the 105. As shown in FIG.

그리고 상기 힌지축(102)과 탄성편(107)의 폭(d1)보다 힌지축(102)과 마찰면(105′)의 폭(d2)이 크도록 구성 하였다.In addition, the width d2 of the hinge shaft 102 and the friction surface 105 'is greater than the width d1 of the hinge shaft 102 and the elastic piece 107.

그리고 탄성편(107)이 휘어지는 간격 (△d)는 힌지축(102)과 탄성편(107)의 폭(d1)에서 힌지축(102)과 마찰면(105′)의 폭(d2)을 뺀 간격으로 하였다.The gap Δd in which the elastic pieces 107 are bent is obtained by subtracting the width d 2 of the hinge axis 102 and the friction surface 105 ′ from the width d 1 of the hinge axis 102 and the elastic piece 107. At intervals.

도면중 미설명부호 108은 뚜껑 (101)이 닫혔을 때 걸쇠 (109)를 풀어주는 보턴이다.Reference numeral 108 in the figure is a button to release the latch 109 when the lid 101 is closed.

이와같이 구성된 본 발명의 작용, 효과를 제3도 내지 제6도에 의하여 상세히 설명한다.The operation and effects of the present invention configured as described above will be described in detail with reference to FIGS. 3 to 6.

전기밥솥을 사용하기 위하여 버튼(10)을 눌러주게 되면 괘정장치가 해정되면서 뚜껑 (101)이 힌지축(102)을 중심으로 회전하면서 열린다.When the button 10 is pressed in order to use an electric rice cooker, the lid 101 is released while rotating the lid 101 about the hinge shaft 102.

즉, 힌지축(102)에 축설되어 있는 탄성부재 (104)의 일단은 몸체 (103)에 지지되고 타단은 뚜껑 (101)내에 고정되어 있기 때문에 탄성부재 (104)의 탄력에 의하여 뚜껑 (101)이 열리는 것이다.That is, since one end of the elastic member 104 arranged on the hinge shaft 102 is supported by the body 103 and the other end is fixed in the lid 101, the lid 101 is formed by the elasticity of the elastic member 104. Will be opened.

이와같이 뚜껑 (101)이 열리게 되면 제6도와 같이 뚜껑 (101)에 고정된 탄성편 (107)이 몸체 (103)에 형성된 힌지기둥(105)의 마찰면(105′)에 닿게 된다.When the lid 101 is opened in this manner, as shown in FIG. 6, the elastic piece 107 fixed to the lid 101 comes into contact with the friction surface 105 ′ of the hinge pillar 105 formed on the body 103.

따라서 탄성편(107)이 마찰면(105′)에 닿아 변위를 일으키는 것은 힌주축(102)과 마찰면(105′)의 폭(d2)이 힌지축(102)과 탄성편(107)의 폭(d1)보다 간격 (△d)이 작기 때문에 탄성편(107)이 간격 (△d)만큼 마찰면(105′)에 닿아 밀리게 되어 변위가 발생하는 것이다.Therefore, the elastic piece 107 touches the friction surface 105 'and causes displacement, so that the width d2 of the hinge axis 102 and the friction surface 105' is the width of the hinge shaft 102 and the elastic piece 107. Since the space | interval (DELTA) d is smaller than (d1), the elastic piece 107 will touch the friction surface 105 'by the space | interval (DELTA), and it will push | displace, and a displacement will generate | occur | produce.

이와 같이 본 발명은 뚜껑이 열릴 때 뚜껑이 형성된 탄성편이 몸체에 형성된 힌지기둥의 접촉면에 닿아 마찰을 일으키기 때문에 뚜껑이 부드럽게 열리는 것으로서, 외관으로 장치가 도출되지 아니하기 때문에 외관이 미려하고 뚜껑이 부드럽게 열릴 수 있는 유용한 발명이다.As described above, the present invention is that the lid is opened smoothly because the elastic piece formed in the lid touches the contact surface of the hinge pillar formed on the body when the lid is opened, and the lid is opened smoothly. It is a useful invention that can be.
