The heating element 4 is electrically connected with the main control board 10; the temperature sensor is arranged in the heat insulation cavity 7, and feeds back information to the main control board 10 when the temperature in the heat insulation cavity 7 exceeds a preset temperature, and the main control board 10 is disconnected with a circuit between the heating part 4 according to the feedback information. Therefore, the electric heating furnace of the structure can control the rotating speed of the cooling fan 9 and also can control the working state of the heating element 4, which is mainly represented as follows: when the cooling fan 9 runs at the highest rotation speed and the inside of the heat insulation cavity 7 reaches the preset temperature, the temperature sensor feeds back the information to the main control board 10, and the main control board 10 then disconnects the circuit between the heat insulation component 4 and the heat dissipation component, so as to avoid a series of problems caused by the temperature rise inside the heat insulation cavity 7.
It should be noted that, in the above case, after the main control board 10 breaks the circuit with the heat generating member 4, the following two cases can be distinguished:
if the temperature sensor is an NTC thermistor or a kick type temperature control switch, due to the reset function, when the temperature in the heat insulation cavity 7 is reduced to a preset value, the information can be fed back to the main control board 10 through the NTC thermistor or the kick type temperature control switch, a circuit between the main control board 10 and the heating element 4 is recovered, and the circuit is recovered to enter a standby state again for a consumer to use after active operation.
However, if the temperature sensor is a fuse, since the temperature sensor does not have a reset function, even when the temperature in the heat insulation chamber 7 is reduced to a preset value, the circuit between the main control board 10 and the heat generating member 4 cannot be restored.
Specifically, the temperature sensor is an NTC thermistor 30, or a snap-action temperature control switch, or a fuse, which is located on the bottom side, or the outer side, or the upper side of the heat generating element 4, and is fixedly disposed in the heat insulating chamber 7.

The temperature sensor of the embodiment is preferably an NTC thermistor 30, and when the NTC thermistor 30 works, the resistance value of the NTC thermistor will rapidly decrease along with the temperature rise in the heat insulation cavity 7, and by using this characteristic, the NTC thermistor 30 can sense the information of the temperature change in the heat insulation cavity 7 by measuring the resistance value, so as to achieve the purposes of detecting the temperature and controlling the rotating speed of the fan and the on-off of the circuit of the heating element 4.
Meanwhile, the actual size of the NTC thermistor 30 is flexible and can be as small as 0.010 inch or a small diameter, so that the NTC thermistor can be freely arranged at any position in the heat insulation cavity 7.
The bottom of the furnace body 1 of the embodiment is further provided with a bottom plate 3, an air flowing channel 33 is formed between the bottom plate 3, the heat energy recovery cover 5 and the furnace body 1, and the air flowing channel 33 is communicated with the air inlet end of the heat insulation cavity 7.
The top of the furnace body 1 is also provided with a panel 2, the panel 2 is covered on the heating element 4, and a heating area is arranged corresponding to the heating element 4.

When the temperature in the heat insulation cavity 7 rises, the rotating speed of the cooling fan 9 is increased, the problem that the heat energy recovery cover 5 is damaged due to the fact that the temperature in the heat insulation cavity 7 reaches the use limit temperature of the heat energy recovery cover 5 is avoided, and meanwhile, the heat conducted outwards by the heat energy recovery cover 5 through the temperature in the heat insulation cavity 7 can be reduced.
When the temperature in the heat insulation cavity 7 does not reach the preset temperature of the temperature sensor, the heat radiation fan 9 stops rotating or rotates at a slow speed or rotates at different speeds according to the temperature inside the heat insulation cavity 7, so that the purpose of silence can be realized, the heat in the heat insulation cavity 7 can be rapidly increased, and the effect of heat conduction to the panel 2 is improved.
The rotating speed of the heat radiation fan 9 is changed to ensure that the temperature inside the heat insulation cavity 7 is in a preset temperature range and is relatively constant, more heat is conducted to the panel 2, and the damage to components caused by the temperature rise inside the heat insulation cavity 7 is avoided.
In order to reduce the temperature inside the heat insulation cavity 7, a heat dissipation cavity 19 is arranged among the furnace body 1, the panel 2 and the bottom plate 3, and the heat dissipation cavity 19 is communicated with the air outlet end of the heat insulation cavity 7; the wind in the heat insulation chamber 7 is discharged out of the furnace body 1 through the heat dissipation chamber 19.

According to the principle that heat is transferred in all directions, the inside of the electric heating furnace generates a plurality of hot air flows in different directions. Meanwhile, due to the arrangement of the air flow channel 33, when the heat dissipation fan 9 rotates to work, a negative pressure state is formed inside the air flow channel 33, the air outside the furnace body 1 is sucked into the air flow channel 33, guided into the heat insulation cavity 7 and finally discharged out of the furnace body 1 from the heat dissipation cavity 19.
