Meanwhile, the pressure sensor transmits the current pressure value to the controller, and the pressure value transmitted to the controller by the pressure sensor is gradually reduced along with the gradual evaporation of the moisture in the wet towel.
The wet towel is dried, and the weight is not changed any more.
When the controller detects that the pressure value transmitted by the pressure sensor is the same value for two consecutive times, the drying of the wet towel is finished by default (or the change range of the pressure value is lower than a set value, for example, if the difference between the pressure values measured for two adjacent times is less than 1g, the towel is judged to be dried), the controller controls the motor to stop working, and the heater continues to work for a set time a.
When the memory alloy spring rebounds the connecting part to the initial position, the pressure value borne by the pressure sensor is zero, the pressure sensor transmits a signal to the controller, and the controller controls the heater to stop working.
When a plurality of wet towels are continuously hung on the hook and the hook is pulled, when the controller receives a first signal, the controller controls the motor and the heater to work; after the wet towels are dried, when the controller receives the last continuous same pressure value, the controller controls the motor to stop working, the connecting parts rebound together, and each wet towel is dried completely.
