Micro-pressure insulation anti-oxidative electric cooker

Abstract

The invention provides a micro-pressure insulation anti-oxidative electric cooker. The cooker comprises a cooker body, a cooker lid and a gas pressure release valve. The cooker body comprises an outer shell, a middle shell, an inner liner and an electric heating disk. The gas pressure release valve comprises a valve lid, a valve seat, a valve body, a backflow rubber piece and a floating cap. The upper end of the valve body and the lower end of the valve seat are connected. A steam guide pipe extends into the valve seat. The interface of the valve seat is inserted into a steam cavity of the valve lid. The lower end of the steam chamber presses tightly a sealing ring in a sealing groove to seal the liquid from the gas. The upper end of the steam guide pipe is located in a steam chamber which is located at the outer side of a steady-stable-flow plate. The valve body is inserted into a gas release valve installation hole which is located in the cooker lid. The lower end of the valve body protrudes out of the gas release installation hole. After the cooker body is covered by the cooker lid, when the electric cooker does not work, the floating lid and the valve lid are attached to cover the gas release hole, after the electric cooker begins to work, steam with pressure is generated in the cooker, when the steam pressure is strong enough to overcome the weight of the floating lid, the floating lid is elevated, the gas release hole releases the gas to depressurize the cooker, when the cooker is in the temperature keeping stage, after the pressure in the cooker is reduced, the floating lid recovers to prevent the external air from entering the cooker, and prevent the food from oxidizing. The cooker also has an energy-saving feature.

Description

technical field [0001] The invention relates to an electric rice cooker. Background technique [0002] In the current prior art, an electric rice cooker includes a pot body, a pot cover and an exhaust valve. The pot body includes an outer shell, a middle layer, an inner tank and an electric heating plate. There is an exhaust valve installation hole; the exhaust valve and the exhaust valve installation hole can be detachably matched. The problem is: from the beginning to the end of the heating, the inside of the pot is always connected with the atmosphere, there is no pressure in the pot, and the outside air enters to cause the food to oxidize, and the energy consumption is high. Contents of the invention [0003] The object of the present invention is to provide a micro-pressure heat preservation and anti-oxidation electric rice cooker, which has the characteristics of energy saving and anti-oxidation of food. [0004] The present invention is achieved in the following w...
