Before the pressure cooker is uncovered, the connecting rod buckled with the cooker body is removed to be in linkage with the relief valve to move upwards, and high-pressure gas is released and relieved from the cooker; the pressure cooker is simple in structure and convenient to operate, and safety in use of the pressure cooker can be improved.
Description
Technical field
The present invention relates to pressure cooking appliance field, relate in particular to a kind of safe pressure cooking appliance of opening.
Background technology
Existing pressure cooking appliance, particularly electric pressure cooking appliance, pressure exceedes setting value float-controlled valve and is just uncapped in safety buckle by the insertion of pressure jack-up, make upper cover rotate, only have by mention pressure limiting valve or wait for pressure cooker lower the temperature until pot inner pressure is discharged into safety value, float-controlled valve just can decline, user just can open upper cover, ensure and use safety, the disclosed technical scheme of ZL201020299424 that is called float-controlled valve used for pressure cooking utensil as name is exactly the safety device that is subject to pot inner pressure control.Pressure limiting valve, float-controlled valve and uncapping is associated, i.e. pressure limiting valve control pot inner pressure, and pressure control float-controlled valve, the float-controlled valve control action of uncapping, but separate not associated in their structures in prior art.In actual use, in the time that pot inner pressure is not fallen compared with large and float-controlled valve, just cannot open the pot cover of pressure cooker, and user can not mention the disappointing step-down of pressure limiting valve or pressure release degree is inadequate, user impatiently depresses float-controlled valve by force and uncaps with regard to use instrument or finger, but now pot inner pressure is often very large, the instantaneous ejection that in pot, boiling hot food is opened at pot cover, causes security incident.What is more does not mention pressure limiting valve venting not according to lower float-controlled valve yet, but everybody uses the design load that exceeds the safety buckle of uncapping to open by force the upper cover of pressure cooker, causes security incident.
Summary of the invention
The present invention is directed to above-mentioned prior art present situation, provide a kind of must be first the pressure cooking appliance that can open again pot cover after pressure means pressure release.
The present invention solves the problems of the technologies described above adopted technical scheme, a kind ofly open safe pressure cooking appliance, described pressure cooking appliance comprises a pot body, pot cover and is arranged on the safety valve on pot cover, described safety valve comprises pressure limiting valve and pressure release bar, pressure release bar is arranged on pot cover, pressure limiting valve is enclosed within on pressure release bar, it is characterized in that: also comprise that one end is by hinge and the hinged other end of pot cover and a pot connecting rod for body fastening, described connecting rod can swing up and down around hinge; Pressure limiting valve and connection-rod linkage, drive pressure limiting valve to move up and down when connecting rod swings up and down.Technical scheme of the present invention, connecting rod and pot cover are hinged, and connecting rod can swing around hinge; The interlock of connecting rod and pressure limiting valve, connecting rod and pressure limiting valve are dynamically connected and drive pressure limiting valve to move up and down, or connecting rod jack-up pressure limiting valve upwards below the low side of pressure limiting valve, and connecting rod during to lower swing, does not have the pressure limiting valve that lower link is conflicted just can move downward by conducting oneself with dignity; And connecting rod and pot body fastening, before uncapping, must remove the fastening of connecting rod and pot body, be that connecting rod is pulled up, and while pulling up connecting rod, connecting rod rotates around connecting a fulcrum, when rotating, connecting rod links with pressure limiting valve, connecting rod drives pressure limiting valve to move upward, after pressure limiting valve is raised, pressure cooking appliance starts pressure release, and gases at high pressure can send the sound while release from pressure release bar, give the prompting of a kind of danger of people, and then can not continue to uncap.
Described connecting rod is positioned at the side of pressure release bar and is positioned at below pressure limiting valve, drives pressure limiting valve to move up and down when connecting rod swings up and down.Connecting rod, between pressure limiting valve and pressure release bar, can reduce the occupied space of connecting rod, mentions link-type, and the upside of connecting rod will touch the downside of pressure limiting valve, and then by pressure limiting valve jack-up, by the pressure of relief hole on few pressure release bar, gases at high pressure gush.
Described connecting rod middle part has longitudinal through hole, and pressure release bar is through through hole, pressure limiting valve be set in through on the pressure release bar of through hole and be positioned at simultaneously connecting rod above, when connecting rod swings up and down, drive pressure limiting valve to move up and down.Connecting rod is through the through hole on pressure release bar, and pressure release bar passes from through hole, and pressure limiting valve is set on pressure release bar again, mentions link-type, and the part of lower side contacts that the upside of connecting rod will touch pressure limiting valve is more, is conducive to stablize pressure release.
Described connecting rod is positioned at pressure limiting valve upside, pressure limiting valve and being flexibly connected that connecting rod is clearance-type, and the relative connecting rod of pressure limiting valve can slide.Pressure limiting valve is suspended on connecting rod, and pressure limiting valve is step flexible connection with connecting rod, the relative rod slide of pressure limiting valve but can not fall.In the time mentioning connecting rod, connecting rod drives pressure limiting valve to move upward, and then discharges the pressure in pot.
Described pot body is provided with the stopper slot for limiting rod swaying direction.Limit the direction of motion of connecting rod, eliminate the connecting rod dislocation that connecting rod causes to other directions swings, increase the security using.
Described pot cover is provided with the stopper slot for limiting rod swaying direction and amplitude.Limit the direction of motion of connecting rod, eliminate the connecting rod dislocation that connecting rod causes to other directions swings, increase the security using.
Compared with prior art, the present invention must be first opening pot cover after pressure cooking appliance pressure release, simple in structure, easy to operate again, improves the security that pressure cooking appliance uses.
