Abstract

The utility model discloses a kind of electric cooker, including outer pan body, liner and upper cover, liner at the bottom is equipped with heating dish, liner includes side wall and bottom wall, bottom wall central, which upwardly extends, convexes to form hollow cylinder, and hollow cylinder is top closed, and there is lower open mouth to penetrate through bottom wall for bottom；Heating panel surface has heating pillar to hollow cylinder inner cavity protrusion, and the outer surface for heating pillar is bonded with hollow cylinder inner surface；When heating dish heats liner, heating surface is not only liner bottom wall, further increase the side wall of hollow cylinder, whether all it is greatly improved, can not only transmit from bottom to top compared to flat liner or spherical liner, heat transfer area, and it can be transmitted around from center, make the grain of rice positioned at lower part and the superposed grain of rice can synchronize be absorbed into heat, so that food faster but also can be heated more uniformly, the rice grain made it is more uniform it is full, mouthfeel is more preferable.

Description

A kind of electric cooker

Technical field

The utility model relates to a kind of household kitchen cooker, especially a kind of electric cooker.

Background technique

Electric cooker as cooked food especially rice kitchen appliance due to its is convenient and efficient in daily life In be widely used；Electric cooker generally includes the heating dish of outer pan body, upper cover, liner and liner at the bottom, electricity in the prior art Meal liner, usually vertical side wall and horizontal bottom wall, bottom wall is placed in heating dish, during cooking rice, heating dish Heat transmitted by bottom wall, boil to the food in liner, heating surface area of this common flat liner because of bottom surface The time of the small needs that cause to boil is longer, meanwhile, the lower part grain of rice is heated fast, and the top grain of rice is heated slow, and uneven heating and the grain of rice are inhaled Water expansion unevenly also causes the rice mouthfeel made undesirable.

Followed by a kind of electric cooker of spherical liner, the bottom of liner and most of outer surface are in spherical evagination, are increased The heating surface area for having added the grain of rice improves heat transfer efficiency, and can shorten heating time；But the bottom of a pan limited area after all leads to It crosses outer convex spherical and can not achieve qualitative leap to improve electric rice cooker heated effect.The purpose of this utility model is exactly to break through now Have the limitation of mentality of designing in technology, provide it is a kind of can increase substantially food heating surface area and shorten heating time, improve pass The thermal efficiency improves rice and boils the electric cooker of mouthfeel.

Summary of the invention

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of electric cooker, including outer pan body, liner and upper cover, liner at the bottom are equipped with heating dish, and the liner includes side wall And bottom wall, the bottom wall central, which upwardly extends, convexes to form hollow cylinder, and the hollow cylinder is top closed, and bottom has lower spacious Mouth penetrates through the bottom wall；The heating panel surface has heating pillar to hollow cylinder inner cavity protrusion, the heating pillar Outer surface is bonded with the hollow cylinder inner surface.

The hollow cylinder and heating pillar are the round estrade of revolution, are gradually reduced from bottom to top.

The angle of the side wall and center axis thereof of the hollow cylinder and heating pillar is less than 45 °.

The side wall of inner outwardly protrudes the curved wall to form revolution or side wall of inner is vertical wall surface.

The liner bottom wall has the revolution cambered surface of indent, and the recessed camber surface of heating dish is bonded the liner bottom Wall.

The beneficial effects of the utility model are: due to being provided with hollow cylinder in liner, heating panel surface is to hollow cylinder Inner cavity protrusion has heating pillar, and when heating dish heats liner, heating surface is not only liner bottom wall, further increases hollow posts The side wall of body is whether significantly increased compared to flat liner or spherical liner, heat transfer area, food cycle around Around hollow cylinder, liner bottom wall and hollow cylinder simultaneously heat food, can not only transmit from bottom to top, and Can be transmitted around from center, make the grain of rice positioned at lower part and the superposed grain of rice can synchronize be absorbed into heat, conduct heat High-efficient, heating time is short, so that food faster but also can be heated more uniformly, the rice grain made is more uniform full Completely, mouthfeel is more preferable, realizes qualitative leap relative to flat or ball bottom electric cooker.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model；

Fig. 2 is the structural schematic diagram of second of embodiment of the utility model；

Fig. 3 is the structural schematic diagram of the third embodiment of the utility model.

Specific embodiment

Referring to Fig.1, the electric cooker of the utility model, including 1 liner 2 of outer pan body and upper cover 5, liner at the bottom are equipped with heating dish 4, liner 2 includes side wall 21 and bottom wall 22, the natural arc surface as liner in the prior art between bottom wall 22 of side wall 21 Transition is connected, 22 center of liner bottom wall of the utility model, which upwardly extends, convexes to form hollow cylinder 3, the top of hollow cylinder 3 There is lower open mouth 31 to penetrate through the bottom wall 22 for closing, bottom；There is heating on 4 surface of heating dish to the 3 inner cavity protrusion of hollow cylinder The outer surface of pillar 41, heating pillar 41 is bonded with 3 inner surface of hollow cylinder.

Due to being provided with hollow cylinder 3 in liner 2, heating dish 4 has been correspondingly arranged table in heating pillar 41 and hollow cylinder 3 Face paste is closed, and when heating dish 6 heats liner, heating surface is not only liner bottom wall 22, further increases the surrounding of hollow cylinder 3 Side wall, whether compared with the prior art in flat liner or spherical liner, the heat transfer area of the liner of the utility model All it is greatly improved, and the height or diameter that can according to need setting hollow body 3 are to realize different degrees of mention It is high；When food is looped around around hollow cylinder 3, liner bottom wall 22 and hollow cylinder 3 simultaneously heat food, and thermal energy is not only It can transmit, and can be transmitted around from center from bottom to top, be made positioned at the grain of rice of lower part and the superposed grain of rice all Can synchronize and be absorbed into heat, so that food faster but also can be heated more uniformly, the rice grain made it is more uniform it is full, Mouthfeel is more preferable.

Preferably, hollow cylinder 3 and heating pillar 41 are the round estrade of revolution, it is gradually reduced from bottom to top, The production easy to process of the round estrade of revolution, and non-pinnacle at the top of rotary table can avoid touching manpower generation security risk；Hollow cylinder Side wall and the angle of center axis thereof avoid occupying excessive liner space less than 45 °.

Referring to Fig. 2, different from the linear type side wall of liner in Fig. 1, in the present embodiment, the side wall 21 of liner 2 is outwardly protruded The curved wall of revolution is formed, which is conducive to suitable curved wall and hollow cylinder surrounding formation circulation after water boiling, simultaneously The volume that liner can also be increased makes small pot body realize boiling for large capacity.

Referring to the another embodiment of Fig. 3 the utility model, liner bottom wall 22 has the revolution cambered surface of indent, under heating dish 4 It is recessed into curved surfaces and is bonded the liner bottom wall 22, side wall of inner 21 and the 22 natural sparse model transition of liner bottom wall.

Above-mentioned, the only section Example enumerated of technical solutions of the utility model, and not all embodiments cannot be to limit The protection scope of the utility model processed；All goals of the invention that the utility model is realized with essentially identical technological means, are all answered Belong to the protection scope of the utility model.
