Accompanying drawing explanation
Fig. 1 is the structural representation of the heating plate on electric food warmer in prior art;
Fig. 2 is the structural representation of the heating plate on the electric food warmer of the utility model embodiment;
Fig. 3 is the operation principle schematic diagram of the heating plate on the electric food warmer of the utility model embodiment;
Wherein, 1 is Electric heating cooker, and 2 is heating tube, and 3 is temperature controller, and 4 is thermosistor, and 5 is tempilstick, and 6 is temperature measuring head.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
As shown in Figure 1, of the prior art, heating plate on electric food warmer is often only installed a thermosistor 4 at the edge of Electric heating cooker 1, thermosistor 4 is tripping operation power-off in time when the temperature that Electric heating cooker 1 edge detected surpasses uniform temperature, thereby avoids Electric heating cooker 1 because excess Temperature burns.But, the temperature of Electric heating cooker 1 center obviously will be higher than the temperature of marginal position, that is to say, when thermosistor 4 is when the temperature that Electric heating cooker 1 edge detected surpasses uniform temperature, Electric heating cooker 1 center position has surpassed uniform temperature, the phenomenon that so probably just there will be Electric heating cooker 1 to be burnt.
Heating plate on a kind of electric food warmer of the utility model embodiment as shown in Figure 2, comprising: Electric heating cooker 1 and the heating tube 2 that is arranged on Electric heating cooker 1 bottom.
Heating tube 2 is divided into symmetrical two parts, and all from the edge of Electric heating cooker 1 extends to the edge relative with this Electric heating cooker 1, the roundabout center position to Electric heating cooker 1 is electrically connected to.Specifically, roundabout heating tube 2 parts to Electric heating cooker 1 center first stretch out and extend internally afterwards, roughly S-type, the spacing of heating tube 2 that this setup makes to be positioned at Electric heating cooker 1 marginal position is little, and the spacing of heating tube 2 that is positioned at Electric heating cooker 1 center is large, make heating tube 2 there is enough expansion spaces (being positioned at the required expansion space of the heating tube 2 of Electric heating cooker 1 center large) at adstante febre.Junction, center is serially connected with temperature controller 3; temperature controller 3 disconnects the electrical connection of heating tube 2 during higher than preset temperature (uniform temperature value) in the temperature that Electric heating cooker 1 center detected; once temperature controller 3 detects temperature higher than the uniform temperature power-off of will tripping in time, has effectively protected electric food warmer.
