CONSTITUTION: A hinge mechanism of a top cover includes: a hinge bracket(20) formed in a top cover, having a rotatable shaft portion(201) hinged to a body case to connect the top cover with the body case rotatably; a hinge spring(22) having a side inserted into the body case and the other side fixed to the top cover as well as a torsion part inserted into the rotatable shaft portion of the hinge bracket to lift up the top cover through the torsional stress of the torsion part; and a damping spring(30) for preventing the top cover from over-lifting by applying elasticity in the opposite direction of the rotating top cover when the top cover is opened. When the top cover is opened at an opening angle exceeding a specific range, the rotational inertia force of the top cover is absorbed by the elasticity opposite to the rotational direction of the top cover. Thereby, the rotational velocity of the top cover is reduced slowly and the top cover is prevented from over-lifting. In addition, the body case does not move up and down.

Description

전기 압력밥솥의 탑커버 힌지기구{Hinge device for top cover of electric induction heating type rice cooker}Hinge device for top cover of electric induction heating type rice cooker}

본 발명은 전기 압력밥솥에 관한 것으로서, 보다 상세하게는 탑커버가 개방되는 과정에서 발생하는 충격을 감소시킴과 동시에, 과도하게 젖혀지는 현상을 방지할 수 있는 전기 압력밥솥의 탑커버 힌지기구에 관한 것이다.The present invention relates to an electric pressure cooker, and more particularly, to reduce the impact generated in the process of opening the top cover, and at the same time relates to the top cover hinge mechanism of the electric pressure cooker that can prevent the phenomenon of being excessively flipped. will be.

전기 압력밥솥은 전기를 가열원으로 사용하여 취사작용을 행하며, 오븐 내부를 고압으로 유지하여 가열온도를 정상기압에서 보다 높게 함으로써 취사공정을 신속히 이루기 위한 것으로, 도 1에 나타난 것과 같이 오븐(10)과, 상기 오븐(10)이 안착되는 본체 케이스(12)와, 상기 본체 케이스(12)를 개폐하는 탑커버(14)을 포함하여 구성되어 있다.Electric pressure cooker is a cooking operation using electricity as a heating source, to maintain the inside of the oven at a high pressure to achieve a cooking process quickly by raising the heating temperature at a normal atmospheric pressure, the oven 10 as shown in FIG. And a main cover case 12 on which the oven 10 is mounted, and a top cover 14 opening and closing the main body case 12.

여기서, 상기 본체 케이스(12) 내에는 오븐(10)을 가열하기 위한 전기장치가 구비되어 있고, 탑커버(14)에는 오븐(10) 내의 압력을 조절하기 위한 증기 배출밸브(미도시) 등이 구비되어 있는데, 상기 전기장치는 취사 시에 유도전류를 발생시키는 워킹코일(working coil)(16)과, 보온 시에 비교적 약한 발열작용을 행하는 히터(미도시) 등으로 이루어져 있다.Here, the main body case 12 is provided with an electric device for heating the oven 10, the top cover 14 is provided with a steam discharge valve (not shown) for adjusting the pressure in the oven (10) The electric device includes a working coil 16 for generating an induction current during cooking, a heater (not shown) for relatively weak heat generation during warming, and the like.

상술한 바와 같은, 전기 압력밥솥에 의하면 상기 워킹코일(16)에 의해 오븐(10)에 와전류가 유도되고, 와전류로 인해 오븐(10)이 가열됨으로써 취사작용이 이루어지는데, 취사공정에서는 탑커버(14) 내측부가 오븐(10)의 상단에 밀착되고, 증기 배출밸브가 폐쇄된 상태를 유지하기 때문에 밥물이 끓게 되면 증기발생으로 인해 오븐(10) 내부의 압력이 정상기압 보다 높아지게 된다.As described above, according to the electric pressure cooker, the eddy current is induced in the oven 10 by the working coil 16, and the oven 10 is heated by the eddy current. 14) Since the inner part is in close contact with the upper end of the oven 10 and the steam discharge valve is kept closed, when the rice boils, the pressure inside the oven 10 becomes higher than the normal air pressure due to steam generation.

그리고, 압력이 높아짐에 따라 밥물의 온도 역시 정상기압에서의 비등점 (100℃) 보다 높은 온도까지 올라가기 때문에 밥알이 빨리 익게 된다. 취사공정이 종료되면, 워킹코일(16)에 의한 가열이 중단된 상태에서 오븐(10)내의 압력을 그대로 유지하는 뜸공정이 일정 시간동안 진행되고, 뜸공정이 종료된 후에는 증기 배출밸브의 작동에 의해 오븐(10) 내부의 증기가 외부로 배출되어 압력이 낮아진 상태에서 히터에 의해 오븐(10)이 일정한 온도로 약하게 가열되는 보온공정이 진행된다.In addition, as the pressure increases, the temperature of the rice also rises to a temperature higher than the boiling point (100 ° C.) at normal pressure, so the rice grains ripen quickly. When the cooking process is finished, the steaming process for maintaining the pressure in the oven 10 is maintained for a predetermined time while the heating by the working coil 16 is stopped, the steam discharge valve is operated after the steaming process is finished By the steam inside the oven 10 is discharged to the outside by the heater in the state in which the pressure is lowered by the heater 10 is heated to a constant temperature is a thermal insulation process is in progress.

한편, 이와 같은 전기 압력밥솥에서, 탑커버(14)는 힌지기구에 의해 본체 케이스(12)의 일단과 회전 가능한 구조로 취부되어 있는데, 상기 힌지기구는 탑커버(14)를 회동 가능하게 본체 케이스(12)에 연결하는 힌지브라켓(20)과, 그 일단이 본체 케이스(12)의 내측에 삽입 고정되고, 타단이 탑커버(14)의 일단에 고정된 힌지스프링(22)으로 이루어져 있다.On the other hand, in such an electric pressure cooker, the top cover 14 is mounted in a rotatable structure with one end of the main body case 12 by the hinge mechanism, the hinge mechanism is the main case to rotate the top cover 14 The hinge bracket 20 connected to 12 and one end of the hinge bracket 20 are inserted into and fixed to the inner side of the main body case 12, and the other end of the hinge bracket 22 is fixed to one end of the top cover 14.

여기서, 상기 힌지브라켓(20)은 탑커버(14)의 내측에 형성된 구조물로서, 그 일측의 회전축부(201)가 본체 케이스(12)의 일단에 힌지 결합됨으로써 탑커버(14)와 본체 케이스(12)를 회전 가능하게 연결한다.Here, the hinge bracket 20 is a structure formed inside the top cover 14, the top of the cover 14 and the main body case (1) by rotating the shaft portion 201 of one side is hinged to one end of the main body case 12 12) is rotatably connected.

그리고, 상기 힌지스프링(22)은 도 2에 나타난 것과 같이 그 하단이 서로 연결되고, 타단이 분리되어 평행하는 형태로서, 분리된 양단에 각각 비틀림부(221)가 형성된 구조로 이루어져 있으며, 상기 비틀림부(221)가 힌지브라켓(20)의 회전축부(201)에 끼워짐으로써 비틀림부(221)를 중심으로한 회동각도가 탑커버(14)의 개방각도와 일치되도록 장착되어 있다.In addition, the hinge spring 22 has a lower end connected to each other as shown in FIG. 2 and the other end is separated and parallel to each other, and has a structure in which a torsion part 221 is formed on each of the separated ends, and the torsion is performed. The portion 221 is fitted to the rotation shaft 201 of the hinge bracket 20 is mounted so that the rotation angle around the torsion portion 221 coincides with the opening angle of the top cover 14.

상술한 바와 같은 종래의 탑커버 힌지기구의 작용에 대해 설명하면 다음과 같다.Referring to the operation of the conventional top cover hinge mechanism as described above are as follows.

탑커버(14)가 닫힌 상태에서는 힌지스프링(22)의 선단이 탄성적으로 구부러짐으로써 비틀림부(221)에 비틀림 응력이 인가되고, 탑커버(14) 선단의 후크(미도시)가 본체 케이스(12)의 결속기구(미도시)와 결합함으로써 탑커버(14)의 닫힌 상태가 유지되며, 탑커버(14)를 열 경우에는 결속장치를 해제하면 비틀림부(221)의 비틀림 응력에 의해 탑커버(14)가 자동으로 열리게 된다.(도면상 가상선으로 표시)In the state where the top cover 14 is closed, a torsional stress is applied to the torsion part 221 by bending the tip of the hinge spring 22 elastically, and a hook (not shown) at the tip of the top cover 14 is attached to the body case ( The top cover 14 is maintained in a closed state by coupling with a binding mechanism (not shown) of 12). When the top cover 14 is opened, the top cover is distorted by the torsional stress of the torsion part 221 when the binding device is released. (14) will open automatically (shown as an imaginary line in the drawing).

이때, 탑커버(14)가 열리면서 일정각도(대략 90°) 이상으로 회동하게 되면, 힌지브라켓(20)이 본체 케이스(12)의 상단에 걸리고, 힌지스프링(22)의 선단이 비틀림부(221)의 비틀림 각도 변동으로 인해 개방 시와 반대방향으로 탄성지지력을 발휘하게 됨으로써 탑커버(14)의 개방작동이 멈추게 된다.At this time, when the top cover 14 is opened and rotated by a predetermined angle (approximately 90 °) or more, the hinge bracket 20 is caught by the upper end of the body case 12, and the tip of the hinge spring 22 is twisted part 221. Due to the change in the torsion angle of) exerts an elastic bearing force in the opposite direction as the opening time, the opening operation of the top cover 14 is stopped.

그러나, 상술한 바와 같은 종래기술에 의한 탑커버 힌지기구에 의하면, 탑커버(14)의 개방작동에 필요한 힘뿐만 아니라, 개방작동을 저지하는데 필요한 힘 또한 힌지스프링(20)의 탄성적인 비틀림 응력에 주로 의존하기 때문에, 탑커버(14)가 그 개방과정에서 발생하는 강한 회동 관성력에 의해 정상적인 개방각도 이상으로 과도하게 젖혀지는 이른바 오버 리프팅(over lifting)현상이 발생하게 된다.However, according to the top cover hinge mechanism according to the prior art as described above, not only the force required for the opening operation of the top cover 14, but also the force required to prevent the opening operation also affects the elastic torsional stress of the hinge spring 20. Since it depends mainly, the so-called over lifting phenomenon in which the top cover 14 is excessively flipped beyond the normal opening angle by the strong rotational inertia force generated in the opening process occurs.

그리고, 이와 같은 오버 리프팅 현상에 의하면 탑커버(14)가 반동하여 크게 흔들리게 됨으로써 본체 케이스(12)의 전면부가 들썩거리는 요동현상까지 유발되어, 결과적으로 밥솥 전체에 충격이 가해지기 때문에 밥솥의 내구성이 떨어진다는문제점이 발생한다.In addition, according to such an overlifting phenomenon, the top cover 14 is recoiled and shakes greatly, causing the front part of the main body case 12 to shake up, resulting in an impact on the entire rice cooker. This problem occurs.

본 발명은 상기한 종래 문제점을 해결하고자 안출된 것으로, 탑커버의 개방각도가 일정치 이상이 되면 일종의 댐핑작용을 수행함으로써 탑커버의 과도한 흔들림 및 본체의 들썩거림을 방지할 수 있는 전기 압력밥솥의 탑커버 힌지기구 제공을 목적으로 한다.The present invention has been made to solve the above-mentioned conventional problems, when the opening angle of the top cover is more than a predetermined value by performing a kind of damping action of the electric pressure cooker that can prevent excessive shaking of the top cover and shaking of the main body The purpose is to provide a top cover hinge mechanism.

이하, 본 발명의 실시예를 첨부된 도 3과 도 4를 참조로 하여 상세하게 설명하며, 종래기술과 동일한 부분에 대해서는 동일 부호를 부여하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 3 and 4, and like reference numerals refer to like elements.

우선, 본 발명의 실시예에 따른 전기 압력밥솥의 탑커버 힌지기구는 탑커버를 회전 가능하게 본체 케이스에 연결하는 힌지브라켓과 탑커버에 탄성적인 회동력을 가하는 힌지스프링 및, 탑커버의 개방 시, 탑커버의 회동방향에 대향하는 탄성력을 발휘함으로써 탑커버의 오버 리프팅 현상을 방지할 수 있는 댐핑수단을 포함하여 이루어진다.First, the top cover hinge mechanism of the electric pressure cooker according to the embodiment of the present invention is a hinge spring for applying elastic rotational force to the hinge bracket and the top cover to connect the top cover to the main body rotatably, and when the top cover is opened. And a damping means capable of preventing an overlifting phenomenon of the top cover by exerting an elastic force opposite to the rotational direction of the top cover.

여기서, 상기 댐핑수단은 도 3에 나타난 것과 같이 본체 케이스(12)의 상부에 장착되어, 탑커버(14)의 개방각도가 일정각도를 초과할 경우, 그 상단이 힌지브라켓(20)의 일단과 접하여 탄성적으로 변형되는 댐핑스프링(30)과, 상기 댐핑스프링(30)의 일측면을 지지하는 부싱(32)으로 구성되는데, 상기 댐핑스프링(30)은 그 하단이 체결 스크류(S) 등에 의한 스크류 결합방식으로 본체 케이스(12)에 고정되며, 부싱(32)은 힌지브라켓(20)의 힌지축부(201)에 끼워지는 형태로 장착된다.Here, the damping means is mounted on the upper portion of the main body case 12, as shown in Figure 3, when the opening angle of the top cover 14 exceeds a certain angle, the upper end and the one end of the hinge bracket 20 The damping spring 30 is elastically deformed in contact with, and the bushing 32 for supporting one side of the damping spring 30, the damping spring 30 is the lower end by a fastening screw (S) or the like It is fixed to the main body case 12 by a screw coupling method, the bushing 32 is mounted in the form of being fitted to the hinge shaft portion 201 of the hinge bracket 20.

상기 댐핑스프링(30)은 도 4에 나타난 것과 같이 다수회 절곡되고, 그 하단에 본체 케이스(12)와의 스크류 결합을 위한 스크류홀(30a)이 형성된 패널형 부재로서, 형태적인 특성상 적절한 탄성력을 발휘할 수 있는 구조로 이루어져 있다.The damping spring 30 is bent a plurality of times as shown in Figure 4, a panel member formed with a screw hole (30a) for screw coupling with the main body case 12 at the bottom, it is possible to exert an appropriate elastic force in the form of characteristics It consists of structures that can be.

따라서, 상술한 바와 같이 구성된 본 발명의 실시예에 의하면 상기 댐핑수단에 의해 탑커버(14)의 개방 시, 탑커버(14)의 개방각도가 일정치를 초과하는 순간부터는 탑커버(14)의 급격한 회동이 제한되어, 결과적으로 탑커버(14)의 오버 리프팅 현상이 방지되는데, 이에 대해 보다 상세히 설명하면 다음과 같다.Therefore, according to the embodiment of the present invention configured as described above, when the top cover 14 is opened by the damping means, the opening angle of the top cover 14 is increased from a moment when the top cover 14 exceeds a predetermined value. Sudden rotation is limited, as a result, the overlifting phenomenon of the top cover 14 is prevented, which will be described in more detail as follows.

먼저, 탑커버(14)의 개방 시, 상기 탑커버(14)는 그 개방각도가 일정치(약45°)에 도달할 때까지는 정상적인 속도로 열리게 된다.First, when the top cover 14 is opened, the top cover 14 is opened at a normal speed until the opening angle reaches a predetermined value (about 45 °).

탑커버(14)의 개방작동이 계속되어 개방각도가 일정치를 초과하면 댐핑스프링(30)의 상단이 힌지브라켓(20)에 접하여 탄성적으로 구부러지면서(도 3에서 가상선으로 표시) 탑커버(14)의 회동방향에 대향하는 탄성력을 발휘함으로써 탑커버(14)의 회동관성력을 흡수하게 되는데, 이에 따르면 탑커버(14)의 회동속도가 서서히 감소되어 정상적인 개방각도에서 그 회동상태가 정지되므로, 탑커버(14)가 과도하게 뒤로 젖혀지는 오버 리프팅 현상이 발생하지 않게 된다.When the opening operation of the top cover 14 continues and the opening angle exceeds a predetermined value, the top cover of the damping spring 30 is elastically bent in contact with the hinge bracket 20 (indicated by a virtual line in FIG. 3). By exerting an elastic force opposite to the rotational direction of (14), the rotational inertia force of the top cover 14 is absorbed. As a result, the rotational speed of the top cover 14 is gradually reduced to stop the rotational state at a normal opening angle. As a result, the overlifting phenomenon in which the top cover 14 is excessively flipped back does not occur.

이때, 탑커버(14)에 의해 댐핑스프링(30)이 어느 정도 이상 구부러지게 되면, 힌지브라켓(20)의 회동축부(201)에 장착된 부싱(32)에 의해 상기 댐핑스프링(30)의 구부러짐이 일정 각도 내에서 제한되기 때문에 댐핑스프링(30)이 심하게 구부러져 소성 변형되는 것이 방지된다.At this time, when the damping spring 30 is bent to some extent by the top cover 14, the damping spring 30 is bent by the bushing 32 mounted on the pivot shaft 201 of the hinge bracket 20. Since the damping spring 30 is severely bent and plastically deformed, since it is limited within a certain angle.

즉, 상술한 바와 같이 본 발명의 실시예에 의하면 오버 리프팅 현상에 의한 반동작용으로 탑커버(14)가 크게 흔들려 본체 케이스(12)까지 들썩거리게 되는 요동현상이 거의 발생하지 않거나, 발생하더라도 본체 케이스(12)의 요동 폭이 종래에 비해 감소된다.That is, according to the embodiment of the present invention as described above, the top cover 14 is greatly shaken due to the reaction caused by the overlifting phenomenon, so that the shaking phenomenon that causes the body case 12 to shake up hardly occurs or even occurs. The swing width of (12) is reduced compared with the prior art.

본 발명에 따른 전기 압력밥솥의 탑커버 힌지기구에 의하면 탑커버의 개방 시, 개방각도가 일정치를 초과하는 순간부터 댐핑스프링에 의해 탑커버의 회동관성력이 흡수됨으로써 탑커버의 오버 리프팅 현상이 방지되며, 결과적으로 탑커버의 오버 리프팅에 의해 탑커버가 반동하여 본체의 전면부가 들썩거리는 요동현상이 방지되어 밥솥의 내구성이 향상된다.According to the top cover hinge mechanism of the electric pressure cooker according to the present invention, when the top cover is opened, the rotational inertial force of the top cover is absorbed by the damping spring from the moment when the opening angle exceeds a certain value, thereby preventing the overlifting phenomenon of the top cover.
