As a kind of improvement project of the present utility model, temperature sensor element is provided with screening glass, and screening glass surface contacts with the detection position of temperature sensor assembly.Screening glass should have good heat conductivility, very little on the impact of temperature sensor element perception bottom of pot body temperature, and can play to temperature sensor assembly the effect of protection.Preferably, above-mentioned screening glass is aluminium flake.
As a kind of improvement project of the present utility model, above-mentioned through hole cover has silica gel ring, and the edge of screening glass is embedded in silica gel ring.In this programme; silica gel ring can play the effect of supporting screening glass; and silica gel ring and screening glass acting in conjunction can be played the effect of sealing; protect better temperature sensor assembly; because pot body is placed on micro-crystal plate, screening glass can be pressed down, so silica gel ring can allow screening glass to move down a bit of distance.
As a kind of preferred version of the present utility model, said temperature sensor cluster detects position higher than micro-crystal plate upper surface 1-5mm, and optimum is 2-4mm.
As a kind of improvement project of the present utility model, in described installing rack, be also provided with elasticity holder.Preferably, elasticity holder is spring, and spring housing is contained in the outside of installing rack, because pot body is placed on micro-crystal plate, installing rack can be pressed down, and withdraws after pot body, and spring can make installing rack automatic-ascending reset.
As another kind of improvement project of the present utility model, in described installing rack, be also provided with Thermal Cutoffs.
The beneficial effects of the utility model are:
By temperature sensor element, the through hole from micro-crystal plate stretches out electromagnetic oven of the present utility model, directly contacts with bottom of pot body, finds out the temperature of bottom of pot body, thereby reaches accurate detection and control the object of temperature.
