Upper cover of electric pressure rice cooker

Abstract

The invention relates to an upper cover of an electric pressure rice cooker, comprising an inner cover articulated with the cooker body, a lock latch arranged below the inner cover and rotating relative to the inner cover, and a swing handle and a connecting bar which are arranged above the inner cover and can drive the lock latch to rotate; the inner cover is also provided with a steam discharge base with a steam discharge hole and a pressure ball positioned at the upper end of the steam discharge hole; wherein, the inner cover is also provided with a self-righting safety push rod; a self-righting drive swing arm is arranged between the safety push rod and the swing handle; the middle part of the drive swing arm is articulated on the inner cover by a connecting piece; one end of the safety push rod passes through the side wall of the steam discharge base to be right against the pressure ball and the other end thereof can contact the first end of the drive swing arm capable of driving the safety push rod to move; the second end of the drive swing arm is provided with a rapid unloading system which can ensure the pressure ball to depart from the steam discharge hole. Under the condition that the electric rice cooker has pressure inside, the rapid unloading system is employed to ensure the drive swing arm to push the pressure ball to depart from the steam discharge hole, so as to discharge steam and release pressure, thereby realizing rapid and safe uncovering.

Description

technical field [0001] The invention relates to a top cover of a pressure rice cooker, in particular to a top cover of an electric rice cooker which ensures that the rice cooker can be quickly and safely released under pressure so that the top cover can be safely opened, and belongs to the transformation of the top cover of the pressure rice cooker technology. Background technique [0002] The upper cover of the existing pressure rice cooker generally has the following two structures: one structure is that when the electromagnet is not energized, the pressure ball is placed on the exhaust hole for a long time, so that the exhaust hole is closed, and the body of the cooker passes through when there is no pressure. The small hole in the float valve is connected to the atmospheric pressure, and the cold air is discharged from the float valve; when the steam is heated and pressurized, the steam lifts the float valve and seals the pot body, thus forming a closed space to realize ...

AI Technical Summary

Problems solved by technology

When the product with this structure is in the state of unexpected power failure, the electromagnet will automatically make the pressure ball deviate from the steam vent, and the pressure in the pot will be released quickly, which is especially prone to burns for users who are next to the product and who are not prepared for unexpected power failure; in addition The electromagnet of this structure requires a relatively large suction force, resulting in high cost, and it is in the suction state for a long time during the working process, which generates a large amount of heat and is prone to failure.
