Abstract
Disclosed is a pressure relief structure for a pressure cooker, which can not plugged, belonging to the technical field of kitchen utensils. The utility model comprises an inner cooker, a sealing ring and a cover for the inner cooker; wherein the sealing ring is fixed on the cover for the inner cooker and is sealed together with the upper edge of the mouth of the inner cooker; the pressure relief structure also includes a cover for an outer cooker; the cover for the inner cooker is locked on the inner cooker through the cover for the outer cooker; the cover for the inner cooker or the cover for the outer cover or both have the capability of plastic deformation under dangerous pressure. The utility model provides a pressure relief structure for a pressure cooker, which can relieve pressure in a big area and will not be blocked and can avoid the danger that the cooker bursts.
Description
Technical field
The utility model belongs to cooker technical field for kitchen use, is specifically related to a kind of pressure relief of pressure cooker.
Background technology
Present electric pressure cooking saucepan all requires to prevent the pressure security protective device under the pressure anomaly situation, generally need possess the protective device of dual-pressure safety, comprises the pressure relief device after safe pressure device and safe pressure device stop up.The safe pressure device is generally safety valve at present, but because the sectional area of the exhaust passage of safety valve is less, still has blocked possibility.And relevant pressure relief device generally can adopt pressure release window (or gas pressure relief slot) mode to realize the pressure release of cushion rubber, with its pressure release pressure transient of device of pressure release window (or gas pressure relief slot) mode pressure release.
In a word, the pressure cooker that pot body and pot cover are connected by rigid structure, its safety device all are to realize that by auxiliary safety device structure pressure controls the pressure security of abnormal conditions and protect.This supplementary structure device generally all exists the pressure release passage sectional area less, and blocked possibility is still arranged under the extreme case, has the potential safety hazard of quick-fried pot.
Summary of the invention
For the pressure transient of the pressure relief that overcomes existing pressure cooker, have the deficiency of the blocked potential safety hazard that may, have quick-fried pot, the utility model provides a kind of and has realized the large tracts of land pressure release, can not stop up the pressure cooker pressure relief that can not stop up of the potential safety hazard of eliminating quick-fried pot.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of pressure cooker pressure relief that can not stop up, comprise interior pot, sealing ring and inner pot cover, sealing ring is fixed on the inner pot cover, mouthful position, the upper edge sealing of the pot of sealing ring and interior pot, pressure relief also comprises outer pot cover, on the pot, inner pot cover and interior pot formed pressure chamber in inner pot cover was fastened on by outer pot cover; Inner pot cover and/or outer pot cover are to have the pot cover that produces the plastic deformation performance when being subjected to dangerous pressure.
As preferred a kind of scheme: described sealing ring and interior lightly fried dumpling close sealing.
Technical conceive of the present utility model is: pressure relief comprises liner, double-canopy structure (comprising inner pot cover and outer pot cover), sealing ring, interior pot, outer pot, shell.Sealing ring is fixed on the inner pot cover, and with the sealing of fitting of the pot mouthful position, upper edge of interior pot, in inner pot cover is fastened on by outer pot cover on the pot, or outer pot cover is fastened on the outer pot, and inner pot cover is pressed to interior pot, is closing when cover inner pot cover and interior pot of formation one pressure chamber.Pot cover component is made up of inner pot cover and two on outer pot cover; by to the material of inner pot cover and/or outer pot cover and the choose reasonable of thickness; one of both or both material has the performance of plastic deformation; when dangerous pressure occurring in the pot, pot cover component produces outwards distortion, and sealing ring and interior pot gap increase; make sealing ring lose the pressurize effect; pot inner pressure releases from interior pot oral area edge, discharges pot inner pressure rapidly, reaches the safeguard protection effect.
The beneficial effects of the utility model mainly show: 1, releasing pressure automatically during superpressure, and safe and reliable, exhausted do not have the hidden danger of stopping up; 2, simple in structure, make the processing stability height.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, Fig. 2, a kind of pressure cooker pressure relief that can not stop up, pot 2, sealing ring 4 and inner pot cover 2 in comprising, described sealing ring 4 is fixed on the inner pot cover 2, fit and seal in the pot mouthful position, upper edge of described sealing ring 4 and interior pot 2, described pressure relief also comprises outer pot cover 3, and described inner pot cover 2 is fastened on the interior pot 2 by outer pot cover 3; Described inner pot cover 2 and outer pot cover 3 are for having the pot cover that produces the plastic deformation performance when being subjected to dangerous pressure.
Also comprise liner 1, outer pot 6, pot body 7 in the structure shown in Figure 1.
Pot cover component is made up of inner pot cover 2 and 3 two on outer pot cover.By inner pot cover 2 is reached the material of outer pot cover 3 and the choose reasonable of thickness; as the good aluminium alloy of selecting the plastic deformation performance forms and processes; when dangerous pressure occurring in the pot; inner pot cover 3 outside plastic deformations arch upward; outer pot cover 3 also outwards produces plastic deformation with the binding face of inner pot cover 2; both are out of shape stack increases sealing ring 4 and interior pot 5 gaps; make sealing ring 4 lose the pressurize effect; pot inner pressure releases from interior pot 5 oral area edges; discharge pot inner pressure rapidly, reach the safeguard protection effect.
With reference to Fig. 1, Fig. 3, the inner pot cover 2 of present embodiment is for having the pot cover that produces the plastic deformation performance when being subjected to dangerous pressure.
By to the material of inner pot cover 2 and the choose reasonable of thickness, process as selecting the good aluminium alloy of plastic deformation performance to form, outer pot cover 3 still adopts the high strength material to process.When dangerous pressure occurring in the pot, inner pot cover 3 outside plastic deformations arch upward, and sealing ring 4 increases with interior pot 5 gaps, makes sealing ring 4 lose the pressurize effect, and pot inner pressure releases from interior pot 5 oral area edges, discharges pot inner pressure rapidly, reaches the safeguard protection effect.
With reference to Fig. 1, Fig. 4, the outer pot cover 3 of present embodiment is for having the pot cover that produces the plastic deformation performance when being subjected to dangerous pressure.
By the material of external pot cover 3 and the choose reasonable of thickness, process as selecting the good aluminium alloy of plastic deformation performance to form, inner pot cover 2 still adopts the high strength material to process.When dangerous pressure occurring in the pot, inner pot cover 2 outside plastic deformations arch upward, and sealing ring 4 increases with interior pot 5 gaps, makes sealing ring 4 lose the pressurize effect, and pot inner pressure releases from interior pot 5 oral area edges, discharges pot inner pressure rapidly, reaches the safeguard protection effect.
