Description

A kind of pot of liner and the electric cooker with pot liner

Technical field

The utility model relates to a kind of household kitchen cookers, especially a kind of pot of liner and the electric cooker with pot liner.

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, pot liner and pot liner at the bottom, in the prior art Electric cooker inner container, usually vertical side wall and horizontal bottom wall, bottom wall is placed in heating dish, during cooking rice, The heat of heating dish is transmitted by bottom wall, is boiled to the food in liner, this common flat liner because bottom surface by Heat area is small cause to boil needs time it is longer, meanwhile, the lower part grain of rice is heated fast, and the top grain of rice is heated slow, uneven heating and Grain of rice water swelling 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, though The heating surface area of food is so increased, but it is placed in outer pan body and is easy shaking, is not easy to realize between pot liner and upper cover good Good sealing influences the effect that boils, and on the other hand, in order to obtain good heating effect, heating dish upper surface needs to form and ball The spherical of shape liner at the bottom fitting, difficulty of processing and cost of manufacture rise, and spherical pot liner is easy to happen movement, can lead The abrasion for causing liner bottom surface and heating dish, for this purpose, technical staff researches and develops Aided design related to improvement constantly to overcome above-mentioned ask Topic, causes electric cooker whole design complicated and processing cost rises.But increase since the electric cooker heating surface area of spherical liner is opposite Greatly, heating time is relatively uniform with respect to shortening, being heated, and the rice made is more in good taste than pan, still by quality of the life It is required that high and fast pace crowd pursue.

Although spherical liner the bottom of a pan heating surface area is bigger than pan, the bottom of a pan limited area, will such as be further increased after all The heating surface area of food and shortening heating time, and the effect that boils for further increasing rice cannot；And this reality With novel purpose, the limitation of prior art mentality of designing is exactly broken through, providing a kind of can increase substantially food heating surface area And shorten heating time, while the above-mentioned insufficient pot liner of spherical inner container electric rice cooker and electric cooker can be overcome again.

Summary of the invention

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

A kind of pot of liner, including side wall and bottom wall, the bottom wall include central part and surrounding bottom surface, the central part It upwardly extends and convexes to form hollow cylinder, the hollow cylinder is top closed, and there is lower open mouth to penetrate through the bottom wall for bottom；It is described The surrounding bottom surface of bottom wall is plane.

The hollow cylinder is the round estrade of revolution, is gradually reduced from bottom to top.

The side wall of the hollow cylinder and the angle of center axis thereof are 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.

A kind of electric cooker, including pot liner, outer pan body and upper cover, liner at the bottom are equipped with heating dish, and pot liner is using above-mentioned Described in any item pots of liners.

The beneficial effects of the utility model are: due to being provided with hollow cylinder in pot liner, when heating dish heats liner When, heating surface is not only liner bottom wall, the side wall of hollow cylinder is further increased, whether compared to pan liner or ball Shape pot liner, heat transfer area are significantly increased, and food is looped around around hollow cylinder, pot liner bottom wall and hollow posts Body simultaneously heats food, can not only transmit from bottom to top, and can transmit around from center, makes to be located at lower part The grain of rice and the superposed grain of rice can synchronize be absorbed into heat, so that food faster but also can be heated more uniformly, do Rice grain out it is more uniform it is full, mouthfeel is more preferable；The processing of spherical pot liner difficulty can be overcome again simultaneously, easily shake in use and It is not easy to realize the use defect of excellent sealing between upper cover, reduces the complexity of electric cooker product entirety Aided design and adds Work difficulty.

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 pot liner.

Specific embodiment

Referring to Fig.1, the electric cooker of the utility model, including pot liner, outer pan body 4 and upper cover 5, pot liner include side wall 1 With bottom wall 2, natural arc surface connects transition as pot liner in the prior art between side wall 1 and bottom wall 2, and bottom wall 2 wraps Central part 21 and surrounding bottom surface 22 are included, the central part 21 of the utility model, which upwardly extends, convexes to form hollow cylinder 3, hollow Cylinder 3 it is top closed, bottom have lower open mouth 31 penetrate through the bottom wall 2；And the surrounding bottom surface 22 except central part 21 is Plane.

Due to being provided with hollow cylinder 3 in pot liner, when heating dish 6 heats liner, heating surface is not only liner Bottom wall 2 further increases the surrounding side wall of hollow cylinder 3, whether compared with the prior art in pan liner or spherical shape Pot liner, the heat transfer area of the pot liner of the utility model are all greatly improved, and it is hollow to can according to need setting The height or diameter of main body 3 are to realize different degrees of raising；When food is looped around around hollow cylinder 3,2 He of pot liner bottom wall Hollow cylinder 3 simultaneously heats food, and thermal energy can not only transmit from bottom to top, and can pass around from center Pass, make the grain of rice positioned at lower part and the superposed grain of rice can synchronize be absorbed into heat, thus can faster but also more evenly Ground heat food, the rice grain made it is more uniform it is full, mouthfeel is more preferable；Meanwhile the utility model can increase food by Heat area can retain the flat-bottom design of pot liner in the prior art again, avoid the processing of spherical liner difficulty, easily shake in use and with It is not easy to realize the use defect of excellent sealing between upper cover, reduces the complexity and processing of electric cooker product entirety Aided design Difficulty.

Preferably, hollow cylinder 3 is the round estrade of revolution, it is gradually reduced from bottom to top, the round estrade of revolution is just In processing and fabricating, and non-pinnacle at the top of rotary table, it can avoid touching manpower and generate security risk；Hollow cylinder side wall and central shaft The angle of line avoids occupying excessive liner space less than 45 °.

It is different from the linear type side wall of pot liner in Fig. 1 referring to Fig. 2, in the present embodiment, 1 convex of side wall of pot liner The curved wall of revolution is formed out, which is conducive to suitable curved wall and hollow cylinder surrounding formation circulation after water boiling, together When can also increase the volume of liner, so that small pot body is realized boiling for large capacity.

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.

The above-mentioned pot liner of the utility model can not only be suitable for electric cooker, could be applicable to the households such as electric pressure cooking saucepan and cook a meal On tool.
