Abstract
A kind of cast iron pressure cooker as cooking utensil, its pot body, pot cover are cylinder iron made, and adopt at the bottom of the inside spill in its bottom of a pan, increases the heat transfer contact area, and guaranteeing has than good heat transfer efficient, and other structure is identical with the pressure cooker that present people adopt.This pressure cooker has also that manufactured materials source is wide, and price is low, and iron is to advantages such as health are harmless.
Description
The present invention relates to a kind of pressure cooker, the pressure cooker that particularly adopts cast iron to make as cooking utensil.
The pressure cooker of Xiao Shouing all is flat pressure cookers in the market, and its manufactured materials is an aluminium, and this kind pressure cooker price is higher, because flat, heat transfer efficiency is general.And a large amount of aluminium constantly enter human body from food, also can bring potential harmful effect to health.
The purpose of this invention is to provide that a kind of material source is wide, price is lower, and health is not had potential harmful effect, and also pressure cooker preferably of its heat transfer efficiency.
Task of the present invention is finished as follows: with pressure cooker body bottom by flat change into be inside spill at the bottom of.Pot body, pot cover material adopt cast iron, can be malleable cast iron or spheroidal graphite cast-iron.
Fig. 1 is a generalized section of the present invention.
Below in conjunction with accompanying drawing the present invention is described in further detail: the modular construction of this pressure cooker is the inside concave bottom except flat the changing into of pot body (1) bottom by present employing, other parts are roughly all identical, and it is made of pot body, pot cover, flame-arrester vent plug, valve gap, fuse sheet, rubber ring and handle. Its manufactured materials pot cover (2), pot body (1) are all used spheroidal graphite cast-iron, and spheroidal graphite cast-iron has higher intensity, good toughness is arranged, and can satisfy the requirement of pressure cooker. Behind pot cover, pot body and function magnesium iron moulding by casting, on request through 820 ℃～860 ℃ cryogenic normalizings, and then carry out machining and polishing, extexine chromium plating is to increase aesthetic feeling and to strengthen corrosion-resistant antioxygenic property.
Cast iron pressure cooker has following features: manufactured materials source is wide, price is low, iron is harmless and owing to adopt the inside spill the bottom of a pan to health, has increased the heat transfer contact area, and good heat transfer efficiency is arranged, and is particularly suitable for the pressure cooker as family expenses.
Claims (2)
1, a kind of cast iron pressure cooker, it is made up of pot body, pot cover, flame-arrester vent plug, valve gap, fuse sheet, rubber ring and handle, it is characterized in that a pot body (1) bottom is inside spill, and pot body (1), pot cover (2) material are cast iron.
2, pressure cooker according to claim 1 is characterized in that cast iron materials is malleable cast iron or spheroidal graphite cast-iron.
