Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail:
As Figure 1-4, the utility model is about a kind of improvement structure of pressure cooker, and it comprises that a pot body 1, that holds food materials to be cooked forms the pot cover 2 of hermetically-sealed construction and the handle group 3 in order to gripping with pot body 1.
As Figure 1-4, pot body 1 upper end is one to stretch out and be formed with the opening of ring-type pot edge 11, extend to form at least one rib 12 downwards along pot edge 11, improve the intensity of pot mouth, reduce deflection, do not increasing pot body wall thick in the situation that, greatly strengthen the breakdown pressure that pot body can bear, pot cover 2 is fastened on the opening part of pot body 1, pot cover 2 is provided with a sealing ring 4 with the junction of pot body 1, by the space between sealing ring 4 sealed pot covers 2 and pot body 1 junction, to improve the pressure in pressure cooker, these pot cover 2 end face centers are run through and are provided with an exhaust post 21 with steam vent 22, the alarm valve 24 piping be provided with the safety valve 23 of a superpressure exhaust and a superpressure on the pot cover 2 of exhaust post 21 1 sides time, on exhaust post 21, connect the pressure hammer 5 of a conveniently assemble and disassemble, exhaust post 21 constitutes pressure limiting valve with pressure hammer 5, in the time that pressure cooker operating pressure reaches 80kpa left and right, steam meeting jack-up pressure hammer 5 in pot, by steam vent 22 exhaust steams, pot cover 2 is also provided with at least one security window 27 in order to pressure release with the edge of the link of pot body 1, when all valve bodies on pot cover 2 are ineffective or when serious superpressure (when 160kpa-280kpa), pressure cooker internal pressure declines via security window 27, play the effect of pressure release.
As shown in Figure 1, 2, the rib 12 of pot body 1 is one to be located on the circulus of pot edge 11, and the shape of this rib 12 is consistent with the shape of pot edge 11.
Or as shown in Fig. 1,2,4, pot edge 11 is provided with more than two rib 12, each rib 12 is equidistantly located on pot edge 11, forms circulus.
Wherein, rib 12 is formed in one with pot edge 11, pot body 1, and rib 12 is mutually vertical with pot edge 11.
Further, pot body 1 is to be made up of stainless ladle egative film and aluminium flake, aluminium flake is heated to locate bonding in the bottoming of 1600 tons of high strength pressure to pot body bottom with bag egative film after fusing point, form multilayer bottoming, because being heated of aluminium is faster than stainless, so more abundant when heat conduction after bottom adds aluminium flake.Press the composite base test in Stainless steel pressure cooking-vessel standard GB15066-2004, after 260 DEG C ± 10 DEG C drying box constant temperature 5min, cooling 25 times repeatedly of holding chamber warm water, does not ftracture, and does not break off the base.
As shown in Figure 1, pot cover 2 forms the ring edge to downward-extension with pot body 1 link, be located on this ring edge in order to the security window 27 of pressure release, be equidistantly formed with multiple holding divisions 25 that extend to pot cover 2 center curvatures in ring edge lower end, this holding division 25 is connected on rib 12.
As shown in Figure 1,3, the steam vent 22 of pot cover 2 is connected with pot cover 2 inside, be provided with one in steam vent 22 places of pot cover 2 inside and prevent that food materials from blocking the Anti-stop cover 26 of steam vent 22, on the cover wall of this Anti-stop cover 26, be equidistantly provided with multiple through holes 261, in the time that pressure cooker is worked, gas is discharged by the steam vent 22 on exhaust post 21, Anti-stop cover 26 is set below exhaust post 21, can prevent that gas from discharging time, food stops up steam vent 22, and guarantee pressure cooker normally and is safely worked.
Safety valve 23 and alarm valve 24 are provided with stainless steel spring silk, and in the time of pressure rises, the valve rod of safety valve 23 can rise, and can confirm that a pot internal gas pressure rises; In the time there is no pressure in pot, valve rod just falls.And alarm valve 24 is just worked and sends song while only there is superpressure in pot.Wherein, safety valve 23 is to utilize stainless steel spring silk to be controlled sealing, and the safety while blocked by food for exhaust hole in the middle of preventing is established, if because now the interior steam of pot can not get discharge, the pressure and temperature in pot is rising constantly, quite dangerous.In the time that the gentle pressure of temperature is elevated to (112kpa-160kpa), the stainless steel spring silk of safety valve 23 will compress and exhaust, simultaneously; stainless steel spring silk on alarm valve 24 also can compress; send and pipe, a pot interior vapour pressure is reduced, thereby play safeguard protection effect.
As shown in Fig. 1,4, handle group 3 comprise the miniature lever 31 be located on pot body 1, one and the lower handle 32 and that is symmetrically set on pot body 1 of miniature lever 31 be located at the upper handle 33 on pot cover 2.
As shown in Figure 1, on upper handle 33, be provided with a float-controlled valve 34 with the junction of pot cover 2, ensured the security of pot cover folding by float-controlled valve 34.In the time that pressure cooker internal gas pressure rises, just automatic-ascending sealing of float-controlled valve 34, make pressure cooker interior under the state that has air pressure, pot cover 2 can not be opened, and (as: pressure in pressure cooker is in the time that 5kpa is above, on upper handle 33 and lower handle 32, apply the pulling force of 100N, pot cover 2 does not allow to be opened), play the effect of the security of uncapping; And fasten time not in place when pot cover 2, float-controlled valve 34 sealing of just cannot rising, the air pressure in pressure cooker just can not rise, and plays the effect of closing lid security.
The above is only to preferred embodiment of the present utility model; not scope of the present utility model is limited; therefore do not departing under the prerequisite of the utility model design spirit; equivalence that the common engineers and technicians in this area do structure described in the utility model, feature and principle changes or decorates, and all should fall in the protection domain that the utility model applies for a patent.
