Background technology

Electric cooker is a kind of modernization cooker that the multiple processing such as can steam, boil, stew, simmer, boil in a covered pot over a slow fire, and it not only can cook food ripe, and can be incubated, use sanitation and hygiene, do not pollute, time saving and energy saving, be one of indispensable apparatus of housework modernization.Utilize the kitchen appliance of electric heating cooking food, its operating temperature mostly 100 DEG C upper and lower, the multiple cooking operation such as can steam, boil, stew, simmer, boil in a covered pot over a slow fire.Traditional electric cooker generally utilizes electrothermal tube to heat inner bag, and electrothermal tube is installed on electric cooker shell inside bottom, by insulating heat-conductive plate, electrothermal tube is sealed, and inner bag contacts with heat-conducting plate, and heat is passed on inner bag.For the more family of population, electric cooker is disposable need to boil more food materials, thereby the general design of its volume is larger, make inner bag volume also larger, cleaning up is extremely inconvenient, therefore existing large capacity electric cooker is all that inner bag is designed to the structure that can take out at any time, and inner bag and electrothermal tube and heat-conducting plate are the structures of separate type.Although this structure has facilitated cleaning, due between the heat-conducting plate on inner bag bottom and electrothermal tube due to production technology restriction, inevitably can there is gap, easily cause heat loss, the thermal efficiency is lower, formation energy waste.Especially, the mini electric cooker using for single deal, because of its volume small and exquisite, there is not the difficulty in cleaning, if still adopt the structural design of the heat-conducting plate separate type of inner bag and electrothermal tube, not only can not promote the comfort level of use, make on the contrary its thermal loss causing can not be ignored.

Utility model content

The purpose of this utility model is to provide mini electric cooker, and it has can avoid thermal loss, the advantage that the efficiency of heating surface is high.

To achieve these goals, the technical solution adopted in the utility model is as follows: mini electric cooker, comprise shell, inner bag and pot cover, inner bag is arranged in described shell, pot cover covers the opening with sealing inner bag at the peristome of shell, it is characterized in that, also comprise heat-conducting plate, heater and pressing plate, described heat-conducting plate is close to described inner bag bottom outside surface, on described heat-conducting plate, be bent with holding tank, described heater is embedded in described holding tank, described pressing plate two ends are installed on inner bag bottom outside surface by screw, described pressing plate middle part is pushed down described heat-conducting plate and heat-conducting plate is pressed on described inner bag.

Preferably, described heater and described pressing plate are arranged in a crossed manner.

Preferably, between described heat-conducting plate and described inner bag, be also provided with heat conductive silica gel.

Preferably, described pressing plate middle part is also provided with two screws that connect and fix described heat-conducting plate.

Preferably, on described heater, fuse is also installed.

Preferably, on described heater, temperature controller is also installed.

Preferably, on described heater, be also connected with ground lead.

Preferably, the bottom outside surface of described inner bag is also provided with circuit board, and described fuse, temperature controller and ground lead are electrically connected by described circuit board.

Mini electric cooker of the present utility model, directly heater is installed on to inner bag bottom outside surface by heat-conducting plate, by pressing plate, heater and heat-conducting plate are closely pressed on to inner bag bottom again, make tightly to contact between inner bag and heat-conducting plate, heater, avoided the generation in gap, the heat that heater is produced is directly passed on inner bag by heat-conducting plate, can significantly eliminate thermal loss, improve the efficiency of heating surface of mini electric cooker, be particularly suitable for single use.

Detailed description of the invention

Below in conjunction with accompanying drawing and embodiment, the technical solution of the utility model is described.

As depicted in figs. 1 and 2, the utility model is a kind of mini electric cooker, comprise shell 10, inner bag 20 and pot cover 30, inner bag 20 is arranged in described shell 10, pot cover 30 covers the opening with sealing inner bag 20 at the peristome of shell 10, also comprise heat-conducting plate 40, heater 41 and pressing plate 42, described heat-conducting plate 40 is close to described inner bag 20 bottom outside surfaces, on described heat-conducting plate 40, be bent with holding tank 43, described heater 41 is embedded in described holding tank 43, described pressing plate 42 two ends are installed on inner bag 20 bottom outside surfaces by screw, described pressing plate 42 middle parts are pushed down described heat-conducting plate 40 and heat-conducting plate 40 are pressed on described inner bag 20.Mini electric cooker of the present utility model, directly heater 41 is installed on to inner bag 20 bottom outside surfaces by heat-conducting plate 40, by pressing plate 42, heater 41 and heat-conducting plate 40 are closely pressed on to inner bag 20 bottoms again, make tightly to contact between inner bag 20 and heat-conducting plate 40, heater 41, avoid the generation in gap, the heat that heater 41 produces is directly passed on inner bag 20 by heat-conducting plate 40, can significantly eliminate thermal loss, improve the efficiency of heating surface of mini electric cooker, be particularly suitable for single use.

Tightr in order to make to contact between heater 41 and inner bag 20, improve further the efficiency of heating surface, described heater 41 is arranged in a crossed manner with described pressing plate 42, make pressing plate 42 dynamics in the time compressing heater 41 and heat-conducting plate 40 even, the area compressing is larger, therefore heater 41, heat-conducting plate 40 get a promotion with the area of inner bag 20 close contacts, can improve further to a certain extent heat conduction, promote the efficiency of heating surface of mini electric cooker.

In addition, between described heat-conducting plate 40 and described inner bag 20, be also provided with heat conductive silica gel 44, there are good heat-conductive characteristic and insulating properties, one can make insulation between heater 41, heat-conducting plate 40 and inner bag 20, avoid with electrification, two carry out heat conductive silica gel 44 can further eliminate the gap existing between heater 41, heat-conducting plate 40 and inner bag 20, improve their laminating tight ness rating, can effectively avoid the loss in heat conductive process, also can further improve the efficiency of heating surface of mini electric cooker.
