Ceramic electric cooker
Technical field
The utility model relates to a kind of electric cooker, more specifically to a kind of ceramic electric cooker that adopts ceramic liner.
Background technology
Existing ceramic electric cooker, because ceramic thermal coefficient of expansion is less, the uneven just explosion easily of being heated.
The electric cooker of a kind of employing enamel (or pottery) as inner bag disclosed as Chinese patent literature CN2035208 " enamel (or pottery) electric cooker ", it is characterized in that installing the additional electrical gas ket at the waist of electric cooker inner container, make loop or two half-turn ring-types or additional electrical gas ket and heating chassis are fused, do discoid.But this technology is even inadequately to the heating of ceramic liner, the inequality of being heated, explosion easily.
A kind of red porcelain ceramic electric cooker is disclosed as Chinese patent literature CN1167379C " red porcelain ceramic electric cooker ", make electric heating copper coin heater with copper as heat conductor, comprise loam cake, red-clay inner, heat conduction cover dish, heat radiation lining, shell, heater, temperature limiter, heat insulation cup etc.Heat insulation cup by compression spring and installation sheet setting, heat insulation cup of mat and tight contact the at the bottom of the inner bag, by heat insulation in centre bore, play the effect of limit temperature, in addition, also have air-vent, heat radiation window and thermal current discharge channel, it is more even that inner bag is heated, and skin temperature reduces, and improves electrical heating power and improve cooking quality.But this technology is still even inadequately to the heating of ceramic liner, and the structure more complicated.
Summary of the invention
The purpose of this utility model provides a kind of ceramic electric cooker, makes being heated of ceramic liner more even, and the technical scheme of employing is as follows:
Ceramic electric cooker of the present utility model, comprise shell, control device, bracing or strutting arrangement, movable aluminum pot, ceramic liner and main heater, described shell comprises lid and housing, bracing or strutting arrangement is located at the housing inside bottom, main heater is located on the bracing or strutting arrangement, movable aluminum pot is located at the top of the main heater of bracing or strutting arrangement, movable bottom of aluminium pot contacts main heater, ceramic liner is located in the movable aluminum pot, control device is located on the lateral surface of shell, it is characterized in that: the lateral wall of described movable aluminum pot is provided with assisted heating device.Like this, because the effect of assisted heating device, the power of the bracing or strutting arrangement of bottom just can reduce, and also more even to the heating of ceramic liner, is not easy to occur the phenomenon of explosion.
Described assisted heating device comprises a heater, and this heater is circular, and is set on the lateral wall of movable aluminum pot, and Jia Re effect is more even like this.
Described assisted heating device comprises at least two heaters, and it is circular that each heater all is, and be set on the lateral wall of movable aluminum pot.Like this, the ceramic liner that each heater is striven respectively the differing heights place heats, and can better evenly heat, and improve the thermal efficiency of electric cooker.
Described assisted heating device comprises at least two heaters, and each heater is along the circumferentially evenly distribution of the lateral wall of movable aluminum pot.All heaters preferably can form the shape of similar annulus on the lateral wall of movable aluminum pot, Jia Re effect also can compare evenly like this.
Described assisted heating device bottom is the 40%-80% of ceramic liner height to the vertical range of movable bottom of aluminium pot, can effectively play the purpose of even heating like this.
Described bracing or strutting arrangement comprises supporting disk and a plurality of elastic supporting member for supporting optical member, and supporting disk is fixed on the housing inside bottom by elastic supporting member for supporting optical member, and main heater and movable aluminum pot all are located on the supporting disk.Promptly main heater is located on the supporting disk, and movable aluminum pot is located at the top of the main heater of supporting disk.Like this, no matter the height of ceramic liner is smaller or bigger, when housing propped up the pot edge of ceramic liner, inside bottom that can assurance activity aluminum pot contacted with the ceramic liner bottom all the time.
In order to prevent that better heat from leaking, also be provided with heat-insulation layer in the described housing, it is circular that heat-insulation layer is.
In order to increase the pressure in the ceramic liner, improve the efficiency of heating surface, described lid bottom surface is provided with the sealing ring that cooperates with ceramic liner.
For the ease of operation, and reduce volume, described control device is located at the top of lid.Design has been saved volume than traditional electrical pot for cooking rice like this, and also is convenient to the user electric cooker is operated.
The utility model beneficial effect against existing technologies is, ceramic liner is heated evenly, and its whole temperature difference is not too large, avoided the phenomenon of ceramic liner explosion, and two groups of heaters heat simultaneously, improved the thermal efficiency of electric cooker, and reduced volume, also be convenient to user's operation.

Fig. 2 is the cutaway view of preferred embodiment shown in Figure 1.
The specific embodiment
As shown in Figure 1, 2, ceramic electric cooker in this preferred embodiment, comprise shell, control device 3, bracing or strutting arrangement, main heater 8, movable aluminum pot 6 and ceramic liner 5, described shell comprises lid 1 and housing 2, bracing or strutting arrangement is located at housing 2 inside bottom, and main heater 8 is located on the bracing or strutting arrangement, and movable aluminum pot 6 is located at the top of the main heater 8 of bracing or strutting arrangement, movable aluminum pot 6 bottom surfaces contact main heater 8, and ceramic liner 5 is located in the movable aluminum pot 6.
For the ease of operation, and reduce volume, described control device 3 is located at the top of lid 1.Design has been saved volume than traditional electrical pot for cooking rice like this, and also is convenient to the user and operates.
Described housing 2 comprises shell 201 and inner casing 202.
In order to prevent that better heat from leaking, also be provided with heat-insulation layer 11 in the described housing 2, heat-insulation layer 11 is circular, between shell 201 and inner casing 202.
The lateral wall of described movable aluminum pot 6 is provided with assisted heating device 7.Like this, because the effect of assisted heating device 7, the power of the bracing or strutting arrangement of bottom just can reduce, and also more even to the heating of ceramic liner 5, is not easy to occur the phenomenon of explosion.
Described assisted heating device 7 is located on the lateral wall of movable aluminum pot 6, and the assisted heating device bottom is 50% of ceramic liner 5 height to the vertical range of movable aluminum pot 6 bottom surfaces.
Described assisted heating device 7 comprises a heater, and this heater is circular, and is set on the lateral wall of movable aluminum pot 6, and Jia Re effect is more even like this.
Described bracing or strutting arrangement comprises supporting disk 10 and 3 elastic supporting member for supporting optical member 9, and supporting disk 10 is fixed on housing 2 inside bottom by these elastic supporting member for supporting optical member 9.Main heater 8 and movable aluminum pot 6 all are located on the supporting disk 10.Promptly main heater 8 is located on the supporting disk 10, and movable aluminum pot 6 is located at the top of the main heater 8 of supporting disk 10.Like this, no matter the height of ceramic liner 5 is smaller or bigger, when housing 2 propped up the pot edge of ceramic liner 5, inside bottom that can assurance activity aluminum pot 6 contacted with ceramic liner 5 bottoms all the time.
