S200: the time relay starts to count after receiving the heating instruction, and electrifies the socket after a set time length, for example, 10 minutes, and electrifies the plug which is in butt joint with the socket, at the moment, the circuit of the heating device is conducted, and the heating device can start the heating function;
the heating device is started in a delayed manner, so that sufficient reaction time is reserved for a user, for example, when the user finds that clothes in the washing machine are not taken out, the heating system is in an un-started state due to the fact that the set time is not reached, the washing machine is opened at the moment, the operation safety of the user can be effectively guaranteed, and the situation that the system is short-circuited or the heating system is repeatedly opened and closed to cause the service life of heating equipment to be shortened due to the fact that the running heating system is suddenly interrupted can be avoided; on the other hand, the delay starting can ensure that the heating system is started under the condition that the washing machine is in a stable state, so that the service life of the washing machine is ensured. The socket assembly is arranged to ensure accurate alignment, effectively avoid the problems of ageing and damage caused by exposed circuits, and ensure that the plug is in a non-electrified state when in butt joint due to delayed electrification of the time relay, thereby avoiding the phenomena of spark or electricity leakage which possibly occur when the plug and the socket are in butt joint, and ensuring the electricity utilization safety.
S300: the heating device directly heats the door glass, the temperature of the door glass absorbing heat gradually rises and the heat is conducted to the window pad through air so as to heat the window pad, and the residual moisture on the window pad gradually evaporates and dries due to the heating;
the mode of indirectly heating the window pad through the door glass can realize that the heat is more uniformly diffused to the window pad after the door glass directly absorbs the heat of the heating device, thereby avoiding the phenomenon of local overheating of the window pad
S400: in the heating process, the temperature sensor and/or the humidity sensor feed back the detected temperature and/or humidity of the window pad to the main control board in real time, the main control board compares the temperature and/or humidity with a preset value to judge, when the temperature and/or humidity of the window pad reaches the preset value, the main control board stops the heating device, the heating system stops heating the window pad, and therefore the window pad is judged to be sufficiently dried, and single operation of the heating system is finished.
Through temperature sensor and/or humidity transducer's setting, can make heating system in time turn-off when window pad is dry, avoid window pad drying inadequately or influence window pad self even washing machine's life cycle because window pad is overheated many times.
It can be seen that in the window pad heating method of the invention, the window pad is heated in time through the electric connection of the main control board, the time relay, the socket, the plug and the heating device, and the window pad heating system is shut down through the electric connection of the main control board (the temperature sensor and the humidity sensor), so that the aim of timely and effectively drying the window pad is realized on the premise of giving enough reaction time to a user and ensuring the service life cycle of the washing machine.
