Abstract

The invention relates to a lid locking device for electric pressure cooker, which improves the productivity and operation reliability of the electric pressure cooker by fixing the open / close handle of the inner cooker lid and preventing from moving or separating along up-and-down direction. The lid locking device for electric pressure cooker comprises: open / close handle of inner cooker lid; rotating pole which rotates followed by the rotation of open / close handle of inner cooker lid; and locking ring which rotates followed by the rotation of the rotating pole fixing the inner cooker lid on the inner pan and seals the inside of the inner pan. The open / close handle of inner cooker lid comprises a projecting element on the outer surface, which hooks on the terminal of the guide way in order to prevent the open / close handle of inner cooker lid separating.

Description

technical field [0001] The invention relates to a lid locking device for a pressure rice cooker, in particular to a lid locking device for a pressure rice cooker which improves productivity and reduces production costs by assembling an inner pot lid opening / closing handle and a rotating rod. Background technique [0002] Generally, a pressure rice cooker uses a heat source (not shown) using electric power. The pressure electric rice cooker comprises a locking ring 3, a pressure control device (not shown) for maintaining internal pressure and an exhaust device (not shown) for discharging high-temperature and high-pressure steam after the rice is stewed. There is high temperature and high pressure inside, in order to make the product more stable and safe, the locking ring 3 seals the inside of the inner pot 1 by fixing the inner pot lid 2 to the inner pot 1 . [0003] Ordinary pressure rice cooker uses such as Figures 1 to 4 Lid locking device shown. Refer to attached fig...
