Abstract

Disclosed is a low pressure cooker made from refined aluminum, which is a cooking device suitable for various fire sources. The utility model has the same working principle of the public-known pressure cooker with same use effect and safety. The working pressure is low and thus the cooked food has low nutrition loss and delicious taste. The price is one third cheaper.

Description

Low pressure cooker

The utility model is daily refined aluminium goods, a kind of culinary art cooking utensils that are suitable for various burning things which may cause a fire disaster.

Known closed pressure cooker, operating pressure is 100 in the pot ^{± 1}About KPa, a maximum temperature reaches Celsius more than 120 ° in the pot, the food that culinary art is come out, and nutrition is destroyed in a large number, and food also off-flavor often itself.

The purpose of this utility model provides a kind of cook utensil of optimum working pressure, is guaranteeing cooking time, under the situation that result of use and known pressure cooker are equal to, reduces the food nutrition loss, the natural taste of maintenance food.This low pressure pot performance is safe and reliable, and price is than general pressure cooker cheap 1/3rd.

Main points of the present utility model are that low pressure pot pot body, pot cover adopt commercial-purity aluminium plate stretching attenuation punch forming.Pot body bottom and mouth flange wall thickness thereof keep 2.5mm, enclosure wall thickness 2mm, and pot cover wall thickness 1.5mm, sealing ring are placed in pot cover limit flange inner, and sealing closely when guaranteeing pot cover with the pressing of pot body.Sealing back low pressure pot can bear air pressure and reach more than the 250KPa.Pot cover center and its end respectively account for a hole with device bolt gas off-take and flame-arrester vent plug.Pot cover and pot body outside symmetry are equipped with the bakelite handle, so that the low pressure pot is opened freely, end is kept steady.Form concave ring groove on the pot body madial wall, in order to laying double-edged fine-toothed comb.The pressure-control valve valve body is No. 45 steel chrome-faceds, and the valve stamen adopts H62 brass to make.Pressure-control valve gross weight 45g, when the low pressure pot was worked, pressure-control valve was enclosed within on the bolt gas off-take, made a pot interior operating pressure keep 50 ^{+ 10}KPa is constant.When its operating pressure 〉=50 ^{+ 10}During KPa, gas lifts pressure-control valve along the bolt gas off-take, lifts to certain height, and gas is promptly discharged along air leakage hole on the valve body.The flame-arrester vent plug fuse sheet adopts tin pewter, thickness 0.10 ^{+ 0.005}Mm, safety coefficient is 80-100KPa.When the pressure-control valve air leakage hole block or malfunctioning, when a pot internal gas pressure reaches 80-100KPa, the fuse sheet explosion that promptly fuses.Because low pressure pot operating pressure is little, thus can corresponding its pot of minimizing body, the wall thickness of pot cover, the saving raw material.This low pressure pot each than the nearly 1kg raw material of known pressure cooker saving because pressure-control valve weight saving, each valve 55g that saves material, thereby make the single cost of whole pressure cooker descend 1/3.This low pressure pot is the same with usual pressure pot operation principle, and fuel factor equates, and pressure is low, and the nutrient ingredient of food that culinary art is come out destroys little, and it is good that taste of food keeps.This pot promptly can be used as pressure cooker and uses, and also can be used as general aluminum saucepan and uses.

Below in conjunction with accompanying drawing, the utility model is further described.

The low pressure pot is by pot body 1, pot cover 2, pressure-control valve 3, double-edged fine-toothed comb 4, bakelite handle 9,10, sealing ring 11, flame-arrester vent plug 12, bolt gas off-take 13 are formed up and down.Pot body 1 and pot cover 2 aluminium sheet punch forming, pot body madial wall forms groove, in order to laying double-edged fine-toothed comb 4.Pot body mouth flange is identical consistent with pot cover limit flange, and sealing ring 11 is placed in pot cover limit flange inner, and when pot cover and the pressing of pot body, sealing ring is withheld at pot body mouth flange place, thereby makes pot cover and the pressing of pot body seal tight.Pot cover is installed down bakelite handle 9 and 10 with pot body outside symmetry, and the bakelite handle is tightened up by rivet 5, clip 6, half garden screw 7, sunk screw 8, to guarantee that the low pressure pot is open freely, end is kept steady.The bakelite handle adopts and is difficult for the heat-transfer matcrial making.Bolt gas off-take 13 is equipped with at the pot cover top, and when the low pressure pot was worked, pressure-control valve 3 was enclosed within on the bolt gas off-take 13.Fuse sheet is pressed into by hollow nut among the flame-arrester vent plug 12 on pot cover top, to cover the flame-arrester vent plug eyelet.Sealing ring 11 adopts elastomeric material, and is general with high-pressure cooker sealing ring.
