Abstract

The utility model relates to a spring-loaded safety insulating pressure-cooker used for cooking food. The pot body of the utility model is formed by an inner pot body sheathing with an outer pot cover, and an interlayer between the inner port body and the outer pot cover is filled with heat-insulating materials. The edges of an outer-ring-shaped flat base at the upper part of the inner pot body are respectively flipped downwardly and riveted on the outer pot cover, and a rubber sealing ring is arranged on an inner-ring-shaped flat base. The heat-insulating materials are filled in the interlayer of a pan-lid. The edges of a ring-shaped plane of a lower cover turn upwardly to be riveted on the upper cover. Bakelite handles on the both sides of the pot body are respectively fixed with steel timbers, and a shaft lever passes through bearing holes of the steel timbers, wherein, the shaft lever is sheathed with a spring and a bakelite pressure holder. The utility model has the advantages of handy pan-lid, good heat-insulating property, easy use, safety and reliability.

Description

Spring-loaded safety insulating pressure-cooker

The cooker that a kind of cooking is used.

Existing pressure cooker lid snaps together with the pot body.Complex structure, manufacture difficulty is big.Its pot wall is an individual layer, and heat-insulating property is poor.In addition, if safety valve or fusible plug break down, pressure cooker explodes easily, even security incident takes place.Therefore, the working pressure pot is wanted significant care, at every moment needs the people to look after.

No. 922174067 patent has proposed a kind of safe heat preservation pressure pot, can accomplish that making is simple, heat-insulating property is better, safe in utilization.Its operation principle is that heavier pot cover is pressed on the rubber seal, pot interior steam is not leaked and forms pressure.Irritating in its pot cover interlayer has cement mortar and insulation materials such as pearlite wool, asbestos, thereby has pot cover heaviness and the not good enough defective of heat-insulating property.

The purpose of this utility model provides a kind of spring compression type safety heat preservation pressure pot, accomplishes that insulation, safety, pot cover are light and handy.

The purpose of this utility model is achieved in that pot body puts one by inner pan body and do not have the outer pot cover at the end to form, and is plugged with light heat insulation materials such as glass fibre, pearlite wool, asbestos in the interlayer between inner pan body and the outer pot cover.There is ring-like platform outer pot cover upper edge, and inside and outside two ring-like platforms are arranged at inner pan body top, and upset downwards of the edge of outer ring-like platform and riveted are on outer pot collar type platform, and rubber seal is placed on the inner ring type platform.Pot cover is made up of loam cake and lower cover, the outer rim place that is plugged with the light heat insulation material upper and lower cover in the interlayer that upper and lower cover forms is ring-like plane, the ring-like horizontal edge of lower cover upwards overturns also, and riveted forms a downward protruding ring-like boss on the ring-like plane of loam cake.Be fixed with metallic support respectively on the bakelite handle of pot body both sides, axostylus axostyle passes through in the metallic support support holes, and shaft rod upper sleeve is equipped with spring and bakelite pressure clamp, and the two ends of spring are against respectively on bakelite handle and the bakelite pressure clamp.In addition, that place the pot body and function and an onesize chassis, the bottom of a pan are arranged, in insulation material by the glass fabric parcel is housed.

Operation principle is as follows: under the effect of spring, the bakelite pressure clamp is close on the rubber seal pot cover, pot interior steam is not leaked and draws into pressure.Steam pressure increases to certain limit in pot, and promptly pot cover below is stressed greater than the bakelite pressure clamp during to the thrust of pot cover, and pot cover one side will be backed down, and lets out the vapour decompression automatically, the accident of can never blasting.When not heating, the pot body can be put on the chassis and be incubated.

The utility model also has a width and the degree of depth all at the logical vapour groove below 2 millimeters on the ring-like boss of pot cover, purpose is to make to take off to cover the pine that lightens, in order to avoid the ring-like boss of pot cover tightly is bonded on the rubber seal, is difficult for opening.

Compared with the prior art, the utlity model has following characteristics:

1, owing to do not fill in weight such as cement mortar in the interlayer of pot cover, only fill in light heat insulation material, so pot cover becomes lightly, and heat-insulating property improves further, can make pot interior food be incubated more than 6 hours.

2, owing to pot cover weight saving, its pressure to rubber seal also alleviates thereupon, thereby improves the service life of sealing ring.

3, take off lid easily, easy to use, safe and reliable.

Fig. 1 is the spring compression type safety heat preservation pressure Cooker structure schematic diagram that proposes according to the utility model.

Fig. 2 is the chassis structure schematic diagram.

Be described in detail concrete structure of the present utility model below in conjunction with drawings and Examples.

As shown in Figure 1, pot body of the present utility model puts one by inner pan body 1 does not have the outer pot cover 2 at the end to form, be plugged with light heat insulation material in the interlayer between inner pan body 1 and the outer pot cover 2, it is characterized in that outer pot overlaps 2 upper edges ring-like platform 21 is arranged, outer ring-like platform 11 and inner ring type platform 12 are arranged at inner pan body 1 top, upset downwards of the edge of outer ring-like platform 11 and riveted are on outer pot collar type platform 21, rubber seal 13 is placed on the inner ring type platform 12, pot cover is made up of loam cake 3 and lower cover 4, on, be plugged with light heat insulation material in the interlayer that lower cover forms, on, the lower cover outer rim is ring-like plane, lower cover 4 ring-like horizontal edges upwards upset and riveted on loam cake 3 ring-like planes.Constitute protruding ring-like boss 41 downwards, be fixed with metallic support 6 respectively on the pot body both sides bakelite handle 5, axostylus axostyle 7 passes through in metallic support 6 support holes, is set with spring 8 and bakelite pressure clamp 9 on the axostylus axostyle 7, and the two ends of spring 8 are against respectively on bakelite handle 5 and the bakelite pressure clamp.Present embodiment has a width and the degree of depth all at the air channel below 2 millimeters 42 on ring-like boss 41.

As shown in Figure 2, also have a chassis 10 of placing the pot body and function, size is identical with the bottom of a pan, in the insulation material that is wrapped up by glass fabric is housed.
