Abstract
A pressure cooker with an improved sealing structure for bearing higher pressure is composed of an external cooker with a heater on its bottom, an internal cooker with a bottom in contact with said heater and several fastening slots on its upper part, and a cover on said internal cooker and with a downward extended short wall having several slots for matching with said fastening slots on internal cooker.
Description
Technical field
The present invention relates to the field of pressure cooker, particularly the pressure cooker hermetically-sealed construction.
Background technology
Existing pressure cooker daily pressure cooker is to adopt pot cover and the rigidly connected mode of pot body the most common, this rigidly connected structure, because the unsafe factor on principle, just can't avoiding fully using, although taked multiple safety precautions, still have into thousands of mouth pressure pots accident of in use blasting every year in China.The another kind of spiral clamping mode that adopts is realized the daily pressure cooker product that pot cover is connected with the pot body elasticity, though thoroughly solved the unsafe problems in using, but because its structural design scheme causes to substitute common daily pressure cooker to use factor such as make troubles.
As Chinese patent application number is 200410028519.7, denomination of invention is that pot cover passes through the cap-rotating type electric pressure cooking saucepan that metalwork directly connects shell, a kind of pot cover directly connects the cap-rotating type electric pressure cooking saucepan of shell by metalwork, there is metal column at the pot cover center, and the metal latticing is porose, and metal column is incorporated in the hole of metal latticing, metal latticing tail end has the metal pore, there is metal tube the metalwork upper end, and the metal pore is incorporated into metal tube, and bearing pin pierces in the hole of metal tube and metal pore.Metalwork is by riveting, be threaded or be welded to connect the inside or the outside at metal shell, there is float-controlled valve the pot cover appropriate location, when the jail sealing was closed in pot cover rotation contraposition, the working of plastics above the float-controlled valve had the hole or does not just have working of plastics or latticing to cover above the float-controlled valve.It is that pot cover securely is connected on the metal shell by metal latticing and metalwork, in any case pot cover can quick-friedly not fly out yet, has fundamentally solved the safety problem of cap-rotating type electric pressure cooking saucepan maximum.
This invention utilizes metalwork by riveting, be threaded or be welded to connect the inside or the outside at metal shell, and the jail sealing is closed in pot cover rotation contraposition.Such encapsulating method exists certain dangerous.If pressure cooker pressure is excessive, cause the external piece of pot to be pulled to relaxing or coming off by outer pressure in the pot.Thereby reduce the service life of pressure cooker, add and utilize the method processing pot cover rotation contraposition of welding or riveting to close firm mechanism, have the phenomenon that expends processing cost.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming, and a kind of bigger pressure that can bear be provided, pot cover and interior pot to screw fastener more firm, durable, the pressure cooker of long service life.
The present invention realizes like this.A kind of pressure cooker, comprise outer pot, inner pan body and pot cover, establish heater block in the outer pot bottom, inner pan body is placed in the outer pot, the bottom contacts with the heater block of outer pot, and pot cover covers on inner pan body, and pot cover down extends and is provided with shortwall, the shortwall place is provided with groove, and the top of interior pot is provided with the corresponding catching groove of the groove that is provided with on the shortwall that down extends with pot cover.
Pot cover bottom extended spot is a lid in, the inner cap bodily form is an alms bowl body, the inner cap body wall is provided with the flange part on outside anti-limit, flange part has the pot cover sealing ring, groove is located on the wall of interior lid, there is a boss that makes progress in inner cap dignity central authorities, and its cross section is arc line type, and the projecting inward rib of several inside lids evenly is set between boss and the wall.Or the groove on the pot cover, be the round table-like projection of outwards protruding.
Catching groove on the inner pan body is set to the corresponding projection of groove, and inner pan body and interior lid screw.Inner pan body top is provided with corresponding catching groove, and inner pan body and interior lid screw.Set groove is 3～8 roads on the interior lid, and the catching groove on inner pan body top is the quantity equity with it.Interior lid and inner pan body, with and the groove and the catching groove that are arranged at, all drawings on the whole, groove and catching groove are simultaneously outwards or to projecting inward.
Fastening structure design between pot cover of the present invention and the interior pot, novel and simple, in process,,, implement the cell body of drawing as long as on interior lid and inner pan body without any need for welding or riveted joint, pot cover and inner pan body are worked in coordination, make pressure in the use be evenly distributed on one's body the interior pot of pressure cooker, fasten than the several pots of teeth of singly examining in the past on the pot mouthful, pressure concentrates on the pot mouthful, the present invention is more safe and reliable, can guarantee the sealing of pressure cooker again.Sturdy and durable to a certain extent, and the life-span is long.Process of the present invention than in the past fast, economize, have the progress of saving production cost and enhancing productivity.
