Gland type safety pressure cooker

Abstract

The invention discloses a gland type safety pressure cooker which comprises a pot body, a pot cover and a pot bottom. The pot body and the pot bottom are of an integrated structure. The pot bottom isof a three-layer composite structure, and comprises a magnetic stainless steel outer layer, an aluminum interlayer and a food-grade 304 stainless steel inner layer. The pot cover is provided with a pressing and holding beam, an opening and closing locking device, a safety valve, a pressure limiting valve and an exhaust pipe. The pressing and holding beam is fixed on the pot cover through the opening and closing locking device. Pot lugs used for buckling the two ends of the pressing and holding beam are arranged on the two sides of the pot body respectively. A circle of groove is formed in theperiphery of the bottom face of the pot cover, and a sealing ring is placed in the groove. The three-layer composite pot bottom is durable, fast in heat conduction, even in heating, suitable for various stoves such as gas stoves and induction cookers and good in universality. The sealing ring with a U-shaped or V-shaped section is good in sealing performance. The pot cover with the pressing and holding beam, the pressure limiting valve and the safety valve is good in anti-explosion performance, the situation of pot frying is avoided, and the safety performance is high. The pot lugs are of highstrength and are provided with blocking pieces. The pressing and holding beam cannot be displaced to leak air.

Description

technical field [0001] The invention relates to the field of kitchen utensils, in particular to a gland-type safety pressure cooker. Background technique [0002] Pressure cooker cooking food not only has a short cooking time, but also tastes good. It is suitable for food, pharmaceutical processing and cooking of difficult-to-cook dishes. It is widely used in households, hotels and catering industries. Pot body, pot lid, pressure holding beam, pot ears, ventilation pipe, pressure limiting valve, etc., the existing pressure cooker has some defects: the sealing ring of the pot cover is an "O"-shaped sealing ring, which has poor sealing performance; the heat conduction of the bottom of the pot is uneven, And it cannot adapt to various stoves. The thickness of the pot ear is thin and the strength is insufficient. After a long time of use, it will deform and cause poor crimping effect. Moreover, only the top horizontal section of the pot ear buckles the holding beam, and the hold...

[0002] Pressure cooker cooking food not only has a short cooking time, but also tastes good. It is suitable for food, pharmaceutical processing and cooking of difficult-to-cook dishes. It is widely used in households, hotels and catering industries. Pot body, pot lid, pressure holding beam, pot ears, ventilation pipe, pressure limiting valve, etc., the existing pressure cooker has some defects: the sealing ring of the pot cover is an "O"-shaped sealing ring, which has poor sealing performance; the heat conduction of the bottom of the pot is uneven, And it cannot adapt to various stoves. The thickness of the pot ear is thin and the strength is insufficient. After a long time of use, it will deform and cause poor crimping effect. Moreover, only the top horizontal section of the pot ear buckles the holding beam, and the holding beam is prone to move left and right and cause air leakage.
