Abstract

The utility model relates to the technical field of a pressure cooker, which is manufactured for the purpose of having the advantages of convenient use and reduced space volume. The utility model comprises a cooker body, a cooker lid, a pressure limiting valve, a safety valve and a lid opening and closing safety device. The utility model is characterized in that an upper hand lever is installed on the top of the cooker lid, and the whole hand lever is limited within circumference space on the upper part of the pressure cooker lid; a lower hand lever is a short hand lever within the range of 7 centimeters, and the upper and the lower hand levers are symmetrically installed on both sides of the cooker body. The utility model has the advantages of easy and convenient lid opening and closing, decreased space volume and convenient packing and transportation, and the utility model is suitable for popularization and application on pressure cookers.

Description

Pressure cooker

The utility model relates to a kind of kitchen tools pressure cooker technical field.

Pressure cooker becomes one of indispensable kitchen tools in the Modern Family, and is popular to people deeply, still, the pressure cooker that we use always is based on 14 centimetres of left and right sides long handles, that its shortcoming is that long handle is installed is easily loosening, it is inconvenient to place when frangibility, use, and takes up space more, causes the packed and transported cost to improve.Our its cover closing and opening safety device of wirking pressure pot in addition needs that push pedal is used in the upper handle, says exactly in the time of will opening pot cover that the additional simultaneously push pedal action of rotary handle could be opened, causes like this and uses upward inconvenience.

The purpose of this utility model is to provide the pressure cooker that a kind of structure is firm, easy to use, the volume that takes up space is less, be easy to packed and transported.

The technical solution of the utility model is to realize like this.This pressure cooker includes a pot body, pot cover, sealing ring, pressure limiting valve, safety valve, cover closing and opening safety device, handle, pot cover is fastened on the pot tooth of pot body, pot cover is provided with sealing ring with pot body contact-making surface place simultaneously, the pot cover top is separately installed with pressure limiting valve and safety valve, pot cover, pot have upper and lower handle on one's body, it is characterized in that: upper handle is installed in the pot cover top, and handle integral body is limited in the circuferential spacing of pot cover top; Lower handle is that short handle, the cardinal principle in the 7 centimeter length scopes is installed on pot body both sides symmetrically.

Above-mentioned cover closing and opening safety device is the movable eccentric wheel that is fixed with in the side handle internal cavity that is fixed on the pot cover, the eccentric wheel bottom is provided with ejector pin and withstands on pot body tooth by the perforate of pot cover edge, pass the guard plate perforate by pin on the eccentric wheel and be pressed with guard plate, guard plate has card base to be buckled on the eccentric wheel simultaneously, the front portion has between button hole and the pin and is connected with spring, pot cover guard plate head annex open interior be equipped with can be with pot internal gas pressure size the latching valve of lifting.

This pressure cooker adopts the long handle revolving type to change the pot cover top into and holds revolving type, cover closing and opening safety device need not the push button operation, make pressure cooker open and close convenient easily, fixing more firm, the frangibility not of handle, and reduce pressure cooker and occupy spatial volume, be convenient to packed and transported, outward appearance uniqueness also attractive in appearance.

Below in conjunction with description of drawings embodiment of the present utility model is described in further detail:

As shown in the figure, this pressure cooker has pot body 2, pot cover 15, sealing ring 17, pressure limiting valve 21, safety valve 18, cover closing and opening safety device, handle, after upper handle 10 is connected by screw 11 and supporting base 19, be fixed on the pot cover top, and handle integral body is limited in the circuferential spacing of pot cover top, its inside is hollow form, anti-riot safety device is housed, as shown in Figure 4, sidepiece has venthole, and nick place, corresponding pot cover top has several apertures, is pressed with sealing gasket 14 and pressing plate 13, supporting base 19 also is fixed in the upper handle cavity on the pot cover with screw 20, and there is spring 12 on the top between pressing plate and the supporting base.The pot cover top is equipped with outside safety valve and the pressure limiting valve, also be fixed with short type side handle 4, the movable eccentric wheel 5 that is fixed with in the internal cavities, the eccentric wheel bottom is provided with ejector pin and withstands on pot body tooth by the perforate of pot cover edge, the perforate of passing guard plate 8 by pin 6 on the eccentric wheel is pressed with guard plate 8, guard plate has card base to be buckled on the eccentric wheel simultaneously, the front portion has and is connected with spring 7 between button hole and the pin, near the pot cover open interior guard plate head be equipped with can be with pot internal gas pressure size the latching valve 9 of lifting, as Fig. 8 and shown in Figure 2.Lower handle 3 is installed on pot body both sides symmetrically for the long interior short handle of 7cm, cardinal principle.The pressure limiting valve bottom is with automatic cleaning Anti-stop cover 22, also can be provided with in the pot and steam grate 1 annex, and the pot cover edge also has superpressure steam leakage window 16.

Its operation principle process is as follows: when pot cover, when the pot body fastens and is in initial position, when pressure cooker is heated, because the sealing ring between pot cover and the pot body loses sealing function, can not go up pressure in the pot; Fasten process at pot cover, pot body, the protruding tooth of pot body makes eccentric wheel deflection drive the guard plate level and moves to the pot cover center, pushes down latching valve and makes it to rise and lose sealing function, can not go up pressure in the pot; Have only to pot body and pot cover fasten put in place after, the eccentric wheel position that is in the normal state, spring makes to move behind the guard plate and resets, latching valve freely rises under the vapour pressure effect, the sealing ring that install common latching valve bottom seals pot cover, pressure cooker is just normally gone up pressure work.When pressure cooker pot pressure was in the hole above a certain value, air pressure backed down sealing gasket and pressing plate, and the step-down of losing heart is in a large number pressed the pressure cooker pot and is returned to safe condition.
