Abstract

The utility model relates to an inside viewing pressure cooker which mainly comprises a cooker body, a cooker lid with a sealing ring and a safety valve and a pressure limiting valve which are arranged on the cooker lid, wherein, a through opening is opened on the cooker lid, and a transparent viewing window which is made of high-intensity thermosetting transparent material and is connected with the edge of the through opening on the cooker lid by the sealing ring is fixed on the through opening. Moreover, the transparent viewing window forms a downward spherical surface arc shape, and accordingly, the utility model has the advantages of reasonable and compact structure, convenient operation and reliability; the utility model can visually observe the steaming situation of food in the pressure cooker and can know the steaming state of the food during steaming, so the utility model also has the advantages of increasing using function of the pressure cooker, etc.

Description

Internal visible pressure cooker

The utility model relates to a kind of apparatus that is used for cooking, a kind ofly can belong to the table ware class at the mess kit of high speed cooking food under the high pressure conditions.

Under high pressure conditions, can burn ripe rice quickly, so pressure cooker is popular rapidly.At present, almost the every household is all using pressure cooker to hot plate rice, and especially the family in the city because this not only is the easy to use of it, is that also it can also be energy-conservation, reduces the expenditure of fuel cost.This pressure cooker is relatively simple for structure, mainly by the pot body, and compositions such as safety valve that disposes on the pot cover of band sealing ring and the pot cover and pressure limiting valve, pot cover slides on pot filler rod circle of body top openning by the caulking groove flat-opening type and aims at and can realize sealing.But none is not totally-enclosed, not visible for the present family expenses pressure cooker that uses, this mainly is a safety issue of considering pressure cooker, therefore its pot cover comes out with the disposable die casting of aluminum alloy materials, but in fact, the working pressure of family expenses pressure cooker is also not really high, generally at 80-90KPa, also only about 120KPa, therefore adopting the pin-connected panel pot cover should not be problem to safe popping pressure technically.Because pot cover is not visible, people are difficult to when using pressure cooker know that the food in the pot hots plate situation, also brought inconvenience for the user, especially when putting into water then with bowl splendid attire food and carry out boiling, whether water can not expire in the bowl when having visual pot cover just can't learn boiling, influence the cooking effect of food, can't learn that bowl whether can overturning or the like.

The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of pot cover to be provided with the internal visible pressure cooker of visual windows.

The purpose of this utility model is finished by following technical solution, and it mainly includes a pot body, has the safety valve and the pressure limiting valve that dispose on the pot cover of sealing ring and the pot cover, offers port on described pot cover, is fixed with transparent window on port.

Described transparent window is to make with high strength thermosetting type transparent material, and itself and pot cover port edge are connected with the sealing ring sealing.

Described transparent window is a downward spherical arc shape, and its end is provided with male and fomale(M﹠F), is equipped with sealing ring on the face.

The utility model is arranged on the centre of pot cover with transparent window, and the safety valve on the pot cover and pressure limiting valve are placed on the corresponding side of pot cover.

Accompanying drawing is a structural representation of the present utility model.

Below in conjunction with accompanying drawing the utility model is described in detail: the utility model mainly contains pot body 1, has the pot cover 3 of sealing ring 2, safety valve 4 that disposes on hingle and the pot cover and pressure limiting valve 5.Pot cover 3 is the combining form of flat-opening type switch with pot body 1, pot cover 3 is provided with caulking groove 6, and the openning of pot body 1 is provided with filler rod circle 7, and caulking groove 6 and filler rod circle 7 mutually can be chimeric and be fixedly connected together, utilize the sealing ring 2 between them to be sealed securely.Offer a port in the centre of pot cover 3, the transparent window 8 that the solid type transparent material of fixedly connected useful high-strength hot is made on this port, its edge is tightly connected mutually with sealing ring 9 and port edge, described transparent window 8 be shaped as a downward spherical arc shape, when producing certain pressure in the pot body 1, this air pressure will act on the transparent window 8 of band arc, forces sealing ring 9 jam-packeds at the edge of pot cover port, thereby has played reliable sealing effect.In addition, the pot cover of band cambered surface is converted into tangential force along cambered surface with pressure, thereby makes pot cover and transparent window be subjected to rational stress effect.On two corresponding edges that the utility model is separately positioned on pot cover 3 with the safety valve 4 that disposes on the pot cover and pressure limiting valve 5, promptly split with the limit and putting, be beneficial to the reasonable Arrangement of structure.

The utility model is a kind of improvement to prior art, and it compared with prior art has structure and close Reason, compactness, easy to use, reliably, can observe intuitively the boiling situation of food in the pressure cooker, State when separating food-steaming has increased the characteristics such as use function of pressure cooker.
