The control method of the drum washing machine of the present invention is described below with reference to fig. 10, wherein fig. 10 is a flowchart of the control method of the drum washing machine of the present invention.
As shown in fig. 10, the control method of the drum washing machine of the present invention mainly includes:
s100, controlling the electromagnetic valve 8 to be opened, wherein after a user selects related functions of steam washing and the like of the drum washing machine, the control unit 9 controls the electromagnetic valve 8 to be opened to feed water into the atomizing cavity 42;
s200, when the electromagnetic valve 8 is opened, the ultrasonic atomization sheet 441 is controlled to vibrate to detect the height of the liquid level in the atomization cavity 42, if the electromagnetic valve 8 is opened, the controller 47 controls the driving circuit board 444 to be connected, the driving circuit board 444 drives the ultrasonic atomization sheet 441 to work, and the ultrasonic atomization sheet 441 detects the height of the liquid level in the atomization cavity 42 through vibration; of course, the timing of the detection of the ultrasonic atomization sheet 441 can be adjusted, for example, after the electromagnetic valve 8 is opened for a certain period of time, the ultrasonic atomization sheet 441 is controlled to vibrate to detect the height of the liquid level in the atomization chamber 42.
S300, judging whether the height of the liquid level reaches a set height, if the set height is calculated based on the weight of the clothes or a preset height, and judging whether the height of the liquid level reaches the set height while the ultrasonic atomization sheet 441 detects the height of the liquid level;
s400, selectively controlling the electromagnetic valve 8 to close based on the judgment result; if the liquid level reaches the set height, the control solenoid valve 8 is closed, and if the liquid level does not reach the set height, the ultrasonic atomization sheet 441 continuously detects the height of the liquid level.
Through the control method, the utility model discloses a drum type washing machine can utilize ultrasonic atomization piece 441 to detect the height of liquid level, improves the measurement precision of liquid level to improve drum type washing machine's control accuracy.
The operation of the drum washing machine in one possible embodiment will be described with reference to fig. 1 to 10.
In a possible embodiment, after a user selects a steam washing option on a control panel of the drum washing machine, the electromagnetic valve 8 is opened, water enters the atomizing chamber 42, the ultrasonic atomizing sheet 441 firstly detects the height of the liquid level, after the liquid level reaches a set height, the electromagnetic valve 8 is closed, the controller 47 controls the driving circuit board 444 and the fan 48 to be simultaneously started, the ultrasonic atomizing sheet 441 atomizes water in the atomizing chamber 42, meanwhile, the fan 48 introduces external air into the mounting chamber 43 through the air inlet 4111, the air flow cools the controller 47 through the controller 47 and then flows into the atomizing chamber 42 through the notch 4171, and drives steam atomized by the ultrasonic atomizing sheet 441 to sequentially pass through the first communicating hole 4141, the communicating chamber, the second communicating hole 4142, the communicating pipe, the mist outlet 4113 and the mist outlet pipe 7 and then is sprayed into the inner barrel 2 to treat clothes.
So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
