Abstract

The utility model relates to an explosion-proof and leakage-proof energy-saving pressure cooker, which is characterized in that the edge of a cooker cover engaged with a cooker port presents a hook shape and the edge is matched with a groove of the edge of the pressure cooker port, the edge of the cooker port is thickened from an inlet when the cooker cover is covered, and an anti-blocking net is fixed between an exhaust pipe and an anti-blocking cover which are fixed on the cooker cover; the upper outlet of the exhaust pipe presents a loudspear shape, and the cooker bottom presents a concave arc shape inside the pressure cooker. The utility model can raise pressure in the pressure cooker, and can avoid explosion or gas leakage. The utility model has the advantages that heat energy can be saved and foods cooking time in the pressure cooker can be shortened.

Description

Explosion-proof leakage-proof energy-saving pressure cooker

The utility model is a kind of explosion-proof leakage-proof energy-saving pressure cooker.

At present, the pressure cooker of selling on the market, for preventing its superpressure blast, generally adopt pressure release, so pot inner pressure generally is no more than 100～130KPa, because of pot inner pressure little, the food that boils for difficulty need could ripe through the long period, so lose time and heat energy, seals bad between sealing ring aging or pot cover and pot body, then need the longer time, therefore the nutrition in the food is lost much.

The purpose of this utility model provides a kind of pot inner pressure that makes and raises, and is unlikely to blast or leak gas, and saves heat energy and the explosion-proof leakage-proof energy-saving pressure cooker of service time.

The technical scheme that realizes the utility model purpose is on the basis of original pressure cooker the edge of pot cover with pot mouthful mate to be: "

" hook-shaped, matching with groove on the pot mouth, every section of pot mouthful edge begins progressive additive from the pot cover porch, and be meshed the with it hook of portion of pot cover reduces gradually; Be fixed with anti-network blocking between blast pipe and the Anti-stop cover, the blast pipe upper outlet is horn-like; The bottom of a pan is circular-arc to the pot sunken inside.

Above-mentioned anti-blocking Netcom crosses nut and is fixed in the blast pipe import.

Outage is left in above-mentioned Anti-stop cover bottom.

Above-mentioned pot mouthful diameter is greater than the diameter in the bottom of a pan.

After the utility model adopts technique scheme, the pressure cooker internal pressure is increased, pressure cooker blast and gas leak phenomenon can not occur, can shorten the digestion time of food simultaneously, save heat energy.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the enlarged drawing of pot cover upper air-vent among Fig. 1;

Fig. 3 is the cross section enlarged drawing of the anti-network blocking 8 among Fig. 2.

The utility model is described in further detail below in conjunction with accompanying drawing:

Pressure cooker cover 1 and the pot mouth part that is meshed is identical with the known pressure pot, is divided into 12 parts as present pressure cooker, and a pot mouthful groove is 1/12nd section, and the edge of pot cover 1 bends to hook-shaped, be "

" the shape hook; be meshed with the groove 3 on the pressure cooker mouth edge; make and cover 1 dogging and advance in the pot mouthful groove; the pot body is washed out with pot cover 1 or be out of shape to prevent interior the hyperbar of pot; guarantee the safe air pressure of generation in the pot; every section of pot mouth edge begins progressive additive from pot cover 1 porch, hook on the pot cover 1 is corresponding to be reduced gradually, make pot cover 1 crush seal circle, the pot cover lid is tight, be fixed on the outlet 5 that the blast pipe 2 on the pot cover 1 stretches out on pot cover 1 one ends and be horn-like, the thimble that is beneficial to pressure limiting valve is blocked exhaust pipe mouth 5 better, makes in the pressure that limits and can not leak gas; Blast pipe 2 is fixed with Anti-stop cover 9 on the side in pot cover 1, Anti-stop cover 9 is fixed on the blast pipe 2 by exhaust pipe clamp bracket 11, Anti-stop cover 9 bottoms have outage 7, be fixed with anti-network blocking 8 between blast pipe 2 and the Anti-stop cover 9, it is netted that anti-network blocking 8 usefulness aluminium flakes are pressed into microphone head, and this net is fixed on the nut 6 with screw 10, and nut 6 is fixed on blast pipe 2 terminations, as shown in Figure 2, to guarantee that blast pipe 2 can blocking; For preventing the bottom of a pan 4 temperature distortions, the circular shape of mind-set pot sunken inside during the bottom of a pan 4 made, the center is thicker; The slightly larger in diameter of pot mouthful is 4 diameter in the bottom of a pan, slowing down the pressure to the pot wall, thereby guarantees that pot body and pot cover 1 can not be out of shape under rated pressure; Upper and lower handle 12,13 of the present utility model is fixed on pot cover 1 and pot body 3 one ends, and as shown in Figure 1, root adopts the square iron pipe, guarantees that handle is not loosening or revolve disconnected.

During use, as the donkey of over-cookeding, beef, with the increasing pressure limiting valve of 120～130KPa, make difficult prepared food deposits yields high pressure, high temperature, in the short period maturation, three kinds of form: 50～60KPa of pressure limiting valve, 90～100KPa, the pressure of 120～130KPa.
