The temperature gap Δ t for stating 1 bottom of kettle body, controls the heating work of the electric-heating assembly 3, to keep Δ t in set temperature T range
It is interior, so that the temperature difference of 1 bottom of the kettle body and the electric-heating assembly 3 is unlikely to too big, and make for 1 bottom of kettle body
Thermal shock it is excessive, and cause 1 bottom of kettle body be easy explosion the problem of.
In the present embodiment, step S30 includes:
Step 31, as Δ t < T, control electric-heating assembly 3 and work on;
Step 32, as Δ t >=T, control the electric-heating assembly 3 and stop heating or subtract low-power heating, to keep the temperature
Degree difference Δ t is in the range of setting temperature T.
Δ t >=T can control electric-heating assembly 3 and stop working after a period of time, starting to work, in this way, passing through switching institute
The closing and unlatching of electric-heating assembly 3 are stated, to keep Δ t within the value range of setting, it is of course also possible to by reducing the electricity
The mode of the heating power of hot component 3, to keep Δ t within the value range of setting, and then can be to avoid the electric-heating assembly 3
Frequent start and stop, specific implementation form can be converter technique etc..
The thermal coefficient of the size and glass pot body 1 that set T has relationship, and T size used in different glass materials is not
Unanimously, in the present embodiment, T≤200 DEG C, when Δ t is when within 200 DEG C, the kettle body 1 substantially will not be quick-fried because of thermal shock
It splits, and in order to further decrease the risk of explosion, better, T≤150 DEG C.
The electric-heating assembly 3 includes electric heating part 31 and connects the electric heating part 31 and 1 Base Heat of kettle body
Heat-conducting piece 32 namely the heat-conducting piece 32 be only and most directly contacted with the kettle body 1, in turn, the temperature of heat-conducting piece 32
Influence to kettle body 1 is most directly that in the present embodiment, step S20 is specially:Detect the temperature of the heat-conducting piece 32.Tool
Body, it can be by the way that first temperature sensor 4 be in contact with the heat-conducting piece 32, naturally it is also possible to be directly installed on institute
It states on heat-conducting piece 32, such as can be bonded in by heat-conducting glue on the heat-conducting piece 32, to measure the temperature of the heat-conducting piece 32.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all at this
