본 발명은 전기압력밥솥에 관한 것으로, 좀더 상세하게는 뚜껑이 완전히 닫히지 않은 상태에서는 취사 모드 또는 보온 모드 등이 수행되지 않기 때문에 뚜껑이 완전히 닫히지 않은 상태에서 취사가 진행되어 발생할 수 있는 안전사고를 사전에 방지할 수 있는 전기압력밥솥 및 그 뚜껑 개폐 감지장치에 관한 것이다.The present invention relates to an electric pressure cooker, and more particularly, because the cooking mode or the warming mode is not performed in a state where the lid is not completely closed, the safety accident that may occur due to cooking in a state where the lid is not completely closed in advance. The present invention relates to an electric pressure cooker and a lid opening / closing detection device which can be prevented.

일반적으로 전기압력밥솥은 취사 물이 담긴 밀폐 압력용기(내통 또는 내솥)를 전기적인 가열수단으로 가열하여 취사를 하는 주방조리기기이다.In general, the electric pressure cooker is a kitchen cooking equipment for cooking by heating a closed pressure vessel (inner container or inner pot) containing cooking water by an electric heating means.

통상, 전기압력밥솥은 크게 본체와, 본체 내부에 삽입되며 취사 물(조리 물)이 담기는 내통과, 본체에 개폐 가능하게 설치되는 뚜껑(조립체)으로 나누어질 수 있다.In general, the electric pressure cooker may be divided into a main body, an inner tube inserted into the main body and containing cooking water (cooking water), and a lid (assembly) installed to be opened and closed on the main body.

본체 내부에는 취사, 보온, 증기 배출 등 일련의 동작을 제어하는 제어부와 작동 상태를 표시하는 표시부와, 사용자가 취사 모드 또는 보온 모드 등을 선택하기 위한 조작부 등을 구비한다.The main body is provided with a control unit for controlling a series of operations such as cooking, heat keeping, steam discharge, a display unit for displaying an operating state, and an operation unit for a user to select a cooking mode or a heat keeping mode.

본체 내부에는 내통을 가열하기 위한 IH(Induction Heater)와 같은 가열수단이 구비되어 있다.The inside of the main body is provided with a heating means such as an induction heater (IH) for heating the inner cylinder.

뚜껑은 취사 시 내통의 상부에 놓여져 내통 내부를 밀폐시키는 내통의 뚜껑 역할을 하는 방열판을 구비한다.The lid is provided on the upper portion of the inner cylinder when cooking has a heat sink that serves as a lid of the inner cylinder to seal the inside of the inner cylinder.

전기압력밥솥에 있어서는 취사 물이 담긴 내통이 방열판으로 밀폐된 상태에 서 가열되기 때문에 조리도중 내통의 내부가 항상 고온 고압상태를 유지한다.In the electric pressure cooker, the inner cylinder containing cooking water is heated in a sealed state with a heat sink, so the inside of the inner cylinder always maintains a high temperature and high pressure during cooking.

따라서, 전기압력밥솥 뚜껑이 완전히 닫힌 상태에서 그 다음 동작이 수행되어야 안전사고를 방지할 수 있다.Therefore, the next operation must be performed while the electric pressure cooker lid is completely closed to prevent a safety accident.

그러나, 종래 전기압력밥솥에서는 뚜껑이 완전히 닫혔는지를 판별하는 별도의 감지장치를 구비하고 있지 않고 있기 때문에, 뚜껑이 완전히 닫히지 않은 상태에서 취사가 진행될 수 있고 이로 인해 안전사고의 위험이 있었다.However, since the conventional electric pressure cooker does not have a separate sensing device for determining whether the lid is completely closed, cooking may proceed in a state in which the lid is not completely closed, thereby causing a risk of safety accident.

따라서, 본 발명은 전술한 문제점을 감안한 것으로, 뚜껑이 완전히 닫히지 않은 상태에서는 취사 모드 또는 보온 모드 등이 수행되지 않기 때문에 뚜껑이 완전히 닫히지 않은 상태에서 취사가 진행되어 발생할 수 있는 안전사고를 사전에 방지할 수 있는 전기압력밥솥 및 그 뚜껑 개폐 감지장치를 제공하는 데에 그 목적이 있다.Therefore, the present invention has been made in view of the above-mentioned problems, and thus, the cooking mode or the warming mode is not performed in a state where the lid is not completely closed, thereby preventing a safety accident that may occur due to cooking in a state where the lid is not completely closed.

본 발명의 뚜껑 개폐 감지 유닛(300)은 상기 뚜껑(200)에 설치되는 마그네트(237)와, 상기 마그네트(237)를 감지할 수 있도록 상기 본체(110)에 설치되는 마그네트 센서(238)를 구비한다.Lid opening and closing detection unit 300 of the present invention includes a magnet 237 installed on the lid 200 and a magnet sensor 238 installed on the main body 110 so as to detect the magnet 237. do.

상기 마그네트 센서(238)는 상기 본체(110) 내부에 설치된 제어부(미도시)와 전기적으로 연결되어 있다.The magnet sensor 238 is electrically connected to a controller (not shown) installed inside the main body 110.

상기 뚜껑(200)에는 장착용 브래킷(201)이 형성되고, 상기 장착용 브래킷(201) 안에 상기 마그네트 센서(238)가 끼워져 설치되어 있다.A mounting bracket 201 is formed on the lid 200, and the magnet sensor 238 is fitted into the mounting bracket 201.

상기 본체(110)에는 장착 홈(111)이 형성되고, 상기 장착 홈(111) 안에 상기 마그네트(237)가 장착될 수도 있다.A mounting groove 111 may be formed in the main body 110, and the magnet 237 may be mounted in the mounting groove 111.

뚜껑(200)이 개방되어 있을 때, 마그네트(237)와 마그네트 센서(238)는 떨어지게 되고, 이로 인해 마그네트 센서(238)는 마그네트(237)를 감지하지 못한다.When the lid 200 is open, the magnet 237 and the magnet sensor 238 fall off, which causes the magnet sensor 238 to not detect the magnet 237.

반면에, 뚜껑(200)이 폐쇄되어 있을 때, 마그네트(237)와 마그네트 센서(238)는 근접되고, 이로 인해 마그네트 센서(238)는 마그네트(237)를 감지한다.On the other hand, when the lid 200 is closed, the magnet 237 and the magnet sensor 238 are in proximity, thereby the magnet sensor 238 detects the magnet 237.

상기 마그네트 센서(238)는 상기 본체(120) 내부에 설치된 제어부(미도시)와 전기적으로 연결되어 있다.The magnet sensor 238 is electrically connected to a controller (not shown) installed inside the main body 120.

취사를 하기 위해서는 우선, 내통(120) 안에 취사 물을 담은 후, 내통(120)을 본체(110)에 삽입한 다음 뚜껑(200)을 닫는다.To cook, first, cooking water is contained in the inner cylinder 120, and then the inner cylinder 120 is inserted into the main body 110, and then the lid 200 is closed.

뚜껑(200)을 닫기 직전에는 마그네트 센서(238)가 마그네트(237)와 멀리 떨어져 있기 때문에 마그네트(237)를 감지하여 못한다.Just before the lid 200 is closed, the magnet sensor 238 is far from the magnet 237 and thus cannot detect the magnet 237.

뚜껑(200)이 닫히는 순간, 마그네트 센서(238)와 마그네트(237)가 근접 위치되어 마그네트 센서(238)가 마그네트(237)를 감지한다.As soon as the lid 200 is closed, the magnet sensor 238 and the magnet 237 are proximately positioned so that the magnet sensor 238 detects the magnet 237.

이때 마그네트 센서(238)는 본체(110) 내부에 내장된 제어부에 전기적으로 연결되어 있기 때문에, 제어부는 마그네트 센서(238)로부터 신호를 받아서 뚜껑이 닫힌 것으로 판단한다. 제어부는 뚜껑(200)이 완전히 닫힌 것으로 판단하고, 본체(110) 내부에 전원 인가를 허용한다.At this time, since the magnet sensor 238 is electrically connected to a control unit embedded in the main body 110, the control unit receives a signal from the magnet sensor 238 and determines that the lid is closed.
