Abstract

The utility model belongs to the technical field of electric pressure cookers, in particular to an electric pressure cooker with a round-bottomed inner container. The electric pressure cooker comprises a cooker cover, an outer cooker, an inner container and a heating plate, wherein the cooker cover and the outer cooker are buckled; the inner container is arranged in the outer cooker; the heating plate is arranged under the inner container; the middle hole of the heating plate is provided with a temperature sensor; the bottom of the inner container is in contact with the temperature sensor; the bottom of the inner container is in a circular arc shape; the upper surface of the heating plate is in the circular arc shape; and the upper surface of the heating plate is matched with the bottom of the inner container. The inner container the bottom of which is in the circular arc shape and the heating plate the upper surface of which is in the circular arc shape are adopted, the contact area of the upper surface of the heating plate and the bottom of the inner container is increased, and thereby, the heating area is increased, the heating efficiency is high, the heating speed is high and the cooking effect is good.

Description

A kind of electric pressure cooking saucepan with the round bottom inner bag

Technical field:

The utility model belongs to the electric pressure cooking saucepan technical field, particularly a kind of electric pressure cooking saucepan with the round bottom inner bag.

Background technology:

Electric pressure cooking saucepan is the upgraded product of conventional high-tension pot and electric cooker, it combines the advantage of pressure cooker and electric cooker, the control of employing elastic pressure, dynamic seal (packing), new technology, new constructions such as outer spiral cover, the adjustable electric switch of displacement, the hermetically sealed cooking, pressure are adjustable continuously, have thoroughly solved the safety problem of pressure cooker, have removed usual pressure pot puzzlement consumer potential safety hazard for many years; Its thermal efficiency is greater than 80%, the power saving that saves time (than the ordinary electric rice cooker economize on electricity more than 30%).Electric pressure cooking saucepan has the incomparable advantage of other cooking appliance, can satisfy many-sided culinary art needs, can be fast, safety, realize multiple cooking method automatically, and it is energy-conservation, the characteristic of nutrition is the direction that the modern pursues.

But the inner bag of existing electric pressure cooking saucepan is flat inner bag, and the efficiency of heating surface of flat inner bag is not high, heats inhomogeneously, and firing rate is slow, therefore, influences the culinary art of electric pressure cooking saucepan to food easily.

The utility model content:

The purpose of this utility model is to provide a kind of electric pressure cooking saucepan with the round bottom inner bag at the deficiencies in the prior art, and its heating surface (area) (HS is big, efficiency of heating surface height, and firing rate is fast, cooks effective.

For achieving the above object, the utility model adopts following technical scheme:

A kind of electric pressure cooking saucepan with the round bottom inner bag, it comprises pot cover, outer pot, inner bag, heat-generating disc, pot cover and outer pot fasten, inner bag is arranged in the outer pot, heat-generating disc be arranged at inner bag under, the hole in the middle of the heat-generating disc is provided with temperature sensor, the bottom of inner bag contacts with temperature sensor, the bottom of described inner bag is circular arc, and the upper surface of heat-generating disc is circular arc, and the upper surface of heat-generating disc matches with the bottom of inner bag.

It also comprises sealing ring, and sealing ring is arranged at the edge of pot cover.

It also comprises elastic construction, and elastic construction is arranged on the bottom of outer pot, the bottom Elastic Contact of elastic construction and heat-generating disc.

It also comprises pressure switch, and pressure switch is arranged at the below of outer pot, the bottom of outer pot and pressure switch Elastic Contact.

The centre of the bottom of described inner bag inwardly convexes with protrusion, protrude be arranged at temperature sensor directly over, protrude and cooperate with temperature sensor.

The utility model beneficial effect is:

Adopting the bottom is the heat-generating disc of circular arc for the inner bag of circular arc and upper surface, makes the upper surface of heat-generating disc and the contact area increase of the bottom of inner bag, the heating surface (area) (HS increase, and efficiency of heating surface height, firing rate is fast, cooks effective.

Description of drawings:

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

Reference numeral:

1---pot cover 2---outer pot 3---inner bag

4---heat-generating disc 5---temperature sensor 6---sealing rings

7---elastic construction 8---pressure switch 9---protrusions

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described, sees Fig. 1.

A kind of electric pressure cooking saucepan with the round bottom inner bag, it comprises pot cover 1, outer pot 2, inner bag 3, heat-generating disc 4, elastic construction 7, pressure switch 8, pot cover 1 fastens with outer pot 2, inner bag 3 is arranged in the outer pot 2, heat-generating disc 4 be arranged at inner bag 3 under, hole in the middle of the heat-generating disc 4 is provided with temperature sensor 5, the bottom of inner bag 3 contacts with temperature sensor 5, elastic construction 7 is arranged on the bottom of outer pot 2, the bottom Elastic Contact of elastic construction 7 and heat-generating disc 4, pressure switch 8 is arranged at the below of outer pot 2, the bottom of outer pot 2 and pressure switch 8 Elastic Contact, the bottom of described inner bag 3 is circular arc, and the upper surface of heat-generating disc 4 is circular arc, and the upper surface of heat-generating disc 4 matches with the bottom of inner bag 3.

The bottom of inner bag 3 is circular arc, and the upper surface of heat-generating disc 4 is circular arc, and the upper surface of heat-generating disc 4 matches with the bottom of inner bag 3.Adopting the bottom is the heat-generating disc 4 of circular arc for the inner bag 3 of circular arc and upper surface, change the mode of the plane contact of existing plane heat-generating disc 4 and flat inner bag 3, make original plane contact heating become three-dimensional contact heating, the contact area of the bottom of the upper surface of heat-generating disc 4 and inner bag 3 increases, increase heating surface (area) (HS, make heating more saturated, improve the efficiency of heating surface and firing rate simultaneously, cook effective.
