Rotating operation type pressure cooker with single handle

Abstract

A rotating operation type pressure cooker with a single handle comprises a pot body (001); pot lugs (002) arranged on the pot body (001); a pot cover (004); a movable pressure ring (006) fixed on the pot cover (004); a panel (007); a right bracket (009) and a left bracket (010) mounted on the panel (007); a rotatable handle (008) mounted on the right bracket (009) and the left bracket (010). By rotating the rotatable handle (008), the opening and closing of the pressure ring (006) may be controlled; the pot cover (004) is internally provided with a pressure sealing ring (005), used for the sealing between the pot cover (004) and the pot body (001); the pressure cooker is further provided with a regulating valve (015') and a safety pressure valve. Air can be released to pressurize the regulating valve (015') or to return the regulating valve (015') to zero by rotating the rotatable handle (008) of the pot cover (004) with a hand in a clockwise or counterclockwise manner when the pot cover (004) is opened, the safety pressure valve is lowered, and the pressure ring (006) is expanded, so that the pot cover (004) can be opened or closed. At this time, the rotatable handle (008) is both a lifting handle and an operating handle of a locking mechanism, so the structure is simple and firm.

Description

technical field [0001] The invention relates to a pressure cooker, in particular to a single-handle rotary operation pressure cooker. Background technique [0002] The pressure cooker used for sealed cooking generally steams and cooks food under the pressure inside the pot of 4-110KPa. The pot body and the pot cover are sealed by a sealing ring, and the two are tightly fastened to each other. There is a problem of how to open the lid of this pressure cooker. The existing method of opening the pressure cooker pot lid is: at first trying to reduce the pressure in the pot, when reaching the normal pressure connected with the atmospheric pressure, the pot lid can be opened easily. Try to reduce the air pressure in the pot, usually by opening the regulating valve to quickly deflate or force cooling; or natural cooling for a long time. For a pressure cooker with a high pressure in the pot, if only two gears are set, the water in the pot will often be ejected by the air valve un...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a single-handle rotary operation pressure cooker, which aims to solve the problem that the air valve of the existing pressure cooker is easily blocked by gambling, which causes the regulating valve to be in a sealed state during use, and is prone to safety accidents
