Document Type and Number:
WIPO Patent Application WO/2016/148492
Kind Code:
A1
Abstract:
The present invention relates to a low vacuum and vacuum release device for an electric rice cooker, the device being capable of releasing a vacuum and maintaining a vacuum state by the rotation of an operation lever. The electric rice cooker has: the operation lever provided at the upper part of a lid; and the low vacuum and vacuum release device provided inside the lid, elastically connected to the operation lever such that when the operation lever is rotated, the device rises so as to open an air inlet, thereby releasing the vacuum while external air flows therein, and when the operation lever is released, the device lowers by the elastic force of a spring so as to maintain the vacuum state by blocking the air inlet, wherein the low vacuum and vacuum release device comprises: a housing provided in the inside of the lid; a first pressure opening/closing operation part provided inside the housing and rising or lowering according to the vapor pressure during cooking, thereby opening or closing the first vapor outlet of a first lower sealing member; a second vacuum release operation part provided inside the housing and rising or lowering according to the rotation of the operation lever, thereby opening or closing the air inlet of a second lower sealing member; and a raising/lowering operation connection part provided at the upper part of the housing and raising or lowering the second vacuum release operation part while being mounted with the operation lever.
