Description

Pressure cooker

The utility model relates to a kind of kitchen cooking utensils, particularly a kind of improvement of family expenses pressure cooker.

Existing pressure cooker, there is not engineered safety features mostly, so that the generation high pressure was uncapped and is caused gas burst when misoperation took place the user, bring unnecessary loss to the user, have some pressure cookers to be provided with safeties at present on the market: (1) reaches the requirement of folding lid security with the exhaust of manual ejection sealing ring, but the using method more complicated of this device, cause the maloperation phenomenon of uncapping easily, the top of sealing ring and top sealing ring is damaged, make the pressure cooker forfeiture not reach standard so function is arranged, (2) utilize the float lifting of float-controlled valve and Handleset up and down to realize closing covering self-locking, the penetrating mechanism of uncapping satisfies the security of folding lid, but the float of this device and Handleset up and down, housing construction is comparatively complicated, and cost is too high, and fails to reach folding and cover full-automatic state.(3) utilize lever principle, with the lever sheet spring safety valve and upper and lower handle are linked and realize the security performance that folding is covered, but this device influences the outward appearance of pressure cooker, makes easy tired gas leakage of spring owing to often lifting spring valve, and makes pressure cooker can not reach the performance of sealing.

The utility model is to provide a kind of when folding is covered at the problem of above-mentioned several devices existence, can not cause misoperation, the generation that causes the accident, and simple in structure, safe and reliable pressure cooker.

Pressure cooker of the present utility model comprises a pot body, pot cover, upper handle, lower handle, pot cover and upper handle junction are provided with a valve body 1, one float 2 and O-ring seal 3 are housed in valve body, what be connected with float has putting film 4 and a slide block 6, the handle Luo silk 9 that the lower end of slide block 6 is provided with spring 8 and effect spring guiding is nested together and is installed in the upper handle inner chamber guide-localization groove, concavo-convex fastening of the guide-localization groove of slide block 6 by upper handle and last lower handle or separate and match.Putting film 4 is to be stamped to form by stainless steel, and the circular hole that cooperates with float is arranged at top, the bottom with screw 5 and screw 7 be fastenedly connected with slide block 6.Float is the semi-hollow body of rod, and the bottom has 2-6 pore that is communicated with mesopore.The upper handle head end has the circular hole that cooperates with float, and the middle part has the guide-localization groove that is used to lay slide block, and afterbody has the boss that matches with the lower handle groove.

Pressure cooker of the present utility model is by the improvement of float, putting film, slide block and the handle of valve body, pot cover is closed when tight, pot inner pressure can not raise, in the pot pressure is arranged, pot cover is not opened, showing has air pressure in the pot, still need be depressurized to float and fall and remove interlocking and can uncap, and it is simple in structure, easy to operate, durable in use, safe and reliable.

Be described further below in conjunction with accompanying drawing:

Figure 16 is that the I of Figure 13 is to figure.

Figure 17 is the C-C profile of Figure 14.

Figure 18 is the schematic diagram of float.

Figure 19 is the schematic diagram of valve body.

Among the figure: the 1st, valve body, the 2nd, float, the 3rd, O-ring seal, the 4th, putting film, the 5th, screw, the 6th, slide block, the 7th, screw, the 8th, spring, the 9th, handle screw, the 10th, upper handle, the 11st, lower handle.

When pot cover does not close or do not put in place (tooth of the tooth of pot cover and pot body not have to fasten or fasten fully or upward lower handle do not line up buckling state the time) on, lower handle does not have complete coincidence status, because the securing member slide block 6 of putting film 4 is under the effect of spring 8, slide block 6 is resetted backward, thereby the circular hole of putting film 4 heads can not be aligned with the float 2 that is fixed in the pot cover upper valve body 1, then there is float 2 not rise by the circular hole of putting film 4, float 2 is pushed down by putting film 4 envelopes all the time and can not be overcome deadweight with the increase that pressure is arranged and rise and to cause peak, because float 2 can not rise to O-ring seal 3 is engaged and the position of seal request with valve body 1, thus the spilehole of pot inner vapor by float 2 through float 2 mesopores drain take the dish out of the pot external.

Cover timing when closing, be that upper and lower palm overlaps fully, the slide block bottom guide head of upper handle moves to peak at the skewed slot of lower handle, thereby the circular hole that makes putting film 4 heads that link with it just aligns with float 2 and is concentric, so overcoming normal rising of deadweight under the situation of boosting of heating, float 2 causes the position of O-ring seal and valve body 1 sealing, and the pot body is sealed fully, can boost to the operating pressure requirement.

When uncapping, when not having pressure or air pressure to conduct oneself with dignity less than float in the pot, float 2 falls voluntarily owing to conduct oneself with dignity, and then float 2 is removed with putting film 4 interlocked relationship, and putting film 4 can freely move back and forth so.So the bottom guide head of slide block can freely skid off in the oblique groove of lower handle, to realize uncapping requirement, this situation is only the state of uncapping normally.

When the pot internal gas pressure is conducted oneself with dignity greater than float, float 2 on the valve body whereabouts of can not conducting oneself with dignity, thereby make float 2 pass the circular hole of putting film all the time, because interlocked is with making the putting film 4 can not be reciprocating, so the slide block bottom guide head of upper handle can not be done any motion and come slippage to go out the oblique groove position of lower handle and be captured between in the groove, makes upper and lower handle not uncap.

The utility model pressure cooker has following characteristics:

1, this device does not have the valve body of air pressure indication, i.e. float is when pressure cooker does not fasten to During the position, pot inner pressure can not rise, and steam then outside the float mesopore is discharged pot, is informed usefulness The family again gets togather lid and could use.

2, when pot inner pressure was conducted oneself with dignity greater than float, the float of float-controlled valve still was in locking bit Put, the lower handle interlocked relationship is not disengaged, so pot cover is not opened, and show in the pot Air pressure is arranged, and caution user row uncaps, still need be depressurized to float fall remove interlocking can Uncap.

3, this apparatus structure is succinct, and is easy to operate, is not with any switch, fully by air pressure With handle control, main component adopts stainless steel and intensity plastic production, and is durable in use, is fit to Anyone operates use, and meets GB fully " aluminum pressure cooker reaches safely performance requirement " Standard-required.
