Abrégé

The present invention relates to an electric cooking appliance having a temperature sensor and an automatic opening/closing device, wherein a temperature sensor is installed inside a lid and above a hotplate and is elastically supported such that, by setting the temperature and time according to the cooking material, the degree of cooking of the cooking material, the taste thereof, and the texture thereof can be improved. The electric cooking appliance comprises: a temperature sensor installed on the lower portion of the interior of a lid so as to control the inner temperature of the electric cooking appliance; an automatic opening/closing device installed at the center of the inside the lid such that, according to the pressure, the same is opened and discharges stream or the same is closed and maintains a vacuum state; and a hotplate installed such that the same can be attached to/detached from the lower portion of the lid, a sealing ring being fastened to the outer periphery of the hotplate, wherein the temperature sensor comprises a fixed member fixed inside the lid by a bolt; a guide member coupled inside the fixed member; a temperature sensor tube installed on the lower portion of the guide member and provided with a temperature sensing portion for controlling the inner temperature of an inner pot of the electric cooking device; a temperature sensing element fixed/sealed inside the temperature sensor tube by epoxy; a spring installed inside the fixed member and the guide member so as to elastically support the guide member; a nut provided below the guide member such that the guide member can be supported; and a bolt and a temperature sensing insertion member fastened to the nut and the hotplate, respectively, such that the temperature sensor tube can be inserted and supported.

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.
