Abstract

The invention provides an electric pressure cooker delayed shut-off valve, comprising a pot cover steam vent and a floater and a silicon seal used to seal the steam vent. The floater is connected with a temperature control sheet, and forms a linage structure moving with the temperature control sheet. After temperature distortion occurs to the temperature control sheet, the floater is driven to move to the position of blocking the steam vent. The temperature control sheet is on the position of measuring temperature of the pot cover or measuring temperature of steam of the pot, the steam vent is in a floater base fixed bolt sleeve which is fixed on the pot cover, and the floater is sleeved in the steam vent and the steam vent is sealed by the silicon seal on the lower part. The delayed shut-off valve can make rice in the pot continuously boil until rice grains are about to fully absorb water when rice is cooked to boiled in an electric pressure cooker, and then the electric pressure cooker enters a pressure maintaining tight covering rice state. Grains of the rice cooked by the process are soft and dry, and are tough and chewy to eat, and have obvious rice fragrance. No matter how much rice is cooked in the pot, the electric pressure cooker delayed shut-off valve can make rice in the pot continuously boil until rice grains are about to fully absorb water, and then the electric pressure cooker enters a pressure maintaining tight covering rice state. The electric pressure cooker delayed shut-off valve is rational in structure, and is suitable for mass production.

Description
