The temperature control modules, are connected with temperature inductor, for pass through temperature inductor detect in real time it is described
The temperature (treating as the temperature of food in upper shell 1) of 1 bottom outer surface of shell, when the temperature is more than or equal to default temperature
When angle value, the size of current and direction that the lithium battery 7 is exported to the semiconductor chilling plate 4 are controlled so that the semiconductor
The top surface of cooling piece 4 absorbs the heat (heat that i.e. described 1 bottom of upper shell is transmitted) transmitted from the bottom surface of the heat-conducting plate 3,
And makes the bottom surface of the semiconductor chilling plate 4 discharge heat outward, radiate, to realize to the food in upper shell 1
Object temperature carries out the purpose of refrigeration cool-down；
And when the temperature is less than preset temperature value, control the electricity that the lithium battery 7 is exported to the semiconductor chilling plate 4
Flow size and Orientation (at this moment current direction commutation) so that the top surface of the semiconductor chilling plate 4 generates heat, is led by described
Hot material filled layer 8 is transmitted to the bottom surface of the heat-conducting plate 3, to be heated to the food temperature in upper shell 1, to upper casing
Food in body 1 carries out additional heat processing, realizes the insulation effect to food.
It should be noted that the preset temperature value can be arranged according to the needs of user, under normal circumstances, such as can
Think 30 DEG C.
It should be noted that for the present invention, the semiconductor chilling plate 4 therein makes full use of semi-conducting material
Peltier effect (peltier) effect, when the galvanic couple that direct current is connected by two kinds of different semi-conducting materials, in galvanic couple
Both ends can absorb heat and release heat respectively, and the purpose of refrigeration may be implemented.It is a kind of refrigeration skill for generating and bearing thermal resistance
Art, its main feature is that movement-less part, reliability is also relatively high.
In the present invention, in specific implementation, the bottom of the upper shell 1 preferably holds transcalent material and is made, for example,
The bottom of the upper shell 1 is the bottom of aluminum.
In the present invention, in specific implementation, the lithium battery 7 is located on 1 bottom interior surface of the lower housing, with fully profit
With the space in lower casing 1.
In the present invention, in specific implementation, the temperature control modules can be include a microcontroller or an arteries and veins
