Electric pressure cooker

Abstract

The invention relates to pressure cooker, in particular to an electric pressure cooker. The electric pressure cooker is capable of automatically sealing, preventing overflow during boiling and automatically venting. The electric pressure cooker comprises a pot, a pot cover, a pot sleeve and an electric heating program panel and is characterized in that a first lever and a second lever are sequentially mounted on the pot cover, the left end of the first lever is mounted below an upper pressure valve of the pot cover, and the left end of the second lever is located above the right end of the first lever; a third lever and an electromagnetic valve are mounted at the bottom of the pot sleeve, and the electromagnetic valve is mounted near the left end of the third lever; a transmission lever is mounted on the side in the pot sleeve, the upper end of the transmission rod is located below the right end of the second lever, the lower end of the transmission rod is located above the right end of the third lever, a timer is added to the electric heating program panel, and the electromagnetic valve is connected with the timer. A microcomputer controls the electromagnetic valve to trigger a venting mechanism for venting, venting time and frequency can be set, and boiling and non-boiling control of various cooking functions can be achieved.

Description

technical field [0001] The invention relates to a pressure cooker, in particular to an electric pressure cooker with automatic sealing, non-overflow when boiling, and automatic exhaust. Background technique [0002] Under a certain temperature and a certain pressure, the liquid (moisture in food) can achieve static non-boiling, that is, under normal pressure (one atmospheric pressure) the water temperature is lower than 100°С will not boil, and the electric pressure cooker with an air pressure of 65Kp-75Kp In the body, the water temperature is close to 112°С and does not boil. At this time, the pressure in the pot is released instantly, and the boiling point of the water is lowered, but the water temperature is still maintained, and boiling will inevitably occur. Existing electric pressure cookers cannot automatically exhaust gas to control boiling or non-boiling according to the type of food, and it is easy to forget to manually seal and cause the pot to overflow. If you b...
