Description
Technical field
The present invention relates to washing machine technology field, and more specifically to a kind of drying mechanism, the invention further relates to one kind
Washing machine with above-mentioned drying mechanism.
Background technology
Existing washing machine drying mechanism includes：Air channel, fan, fan electromotor, heater, temperature controller and TEMP
Device；Wherein, fan is arranged in air channel；Fan electromotor is used to drive electric fan to rotate, to provide air flow into air channel；Heating
The air that device is used in heating air duct, temperature controller are used for overtemperature protection, and temperature sensor is used to detect hot-air at ducting outlet
Temperature.
When washing machine runs drying procedure, heater heats to air, there is provided heat；Fan electromotor drives fan to rotate
So as to drive washing machine internal air circulation, it is finally heated after hot-air be brought on the clothing of washing machine internal, Jin Ershi
Now dry.Above-mentioned temperature controller is bi-metallic laminar kind high temperature protection device, and the hot air temperature at ducting outlet exceedes setting temperature
It when spending, can automatically disconnect, to cut off heater, prevent drying course medium temperature from spending height；Temperature sensor goes out for detecting air channel
Hot air temperature at mouthful, the start-stop of heater is controlled according to feedback.
At present, fan electromotor is controlled with heater action by circuit control panel, is respectively arranged with circuit control panel
For controlling the electric motor loop of fan electromotor and heating circuit for controlling heater.But if circuit control panel starts
During fan electromotor, fan electromotor breaks down (for example start failure or be stuck), and the fault feedback signal can not
Effective Feedback will be heated normally to circuit control panel, heater；So, heater is in the idle feelings of fan electromotor
Heated under condition, the air flow property in air channel is poor, is relatively easily caused heat build-up, causes drying mechanism temperature to rise rapidly, deposits
In larger hidden danger on fire, it is easier to burn drying structure.And temperature controller only can be abnormal in the hot air temperature at ducting outlet
Protection is disconnected when high, when the hot air temperature of ducting outlet reaches disconnection protection temperature, the temperature of drying mechanism has reached
Larger high temperature, it still can not avoid hidden danger on fire.
In summary, how to realize in the case of fan electromotor is idle, avoid drying mechanism temperature too high, to reduce
Hidden danger on fire, it is current those skilled in the art technical problem urgently to be resolved hurrily.
The content of the invention
In view of this, it is an object of the invention to provide a kind of drying mechanism, to realize in the idle feelings of fan electromotor
