For another example, in another alternative embodiment, the setting form and setting position of the flow stabilization plate 418 can be adjusted, as long as the adjustment satisfies the condition that the liquid level fluctuation can be reduced when the atomizing chamber 42 is filled with liquid. . For example, the steady flow plate 418 may also be disposed on the inner wall of the atomization chamber 42 or on the first cover, and a certain gap is left between the lower side of the flow stabilizer plate 418 and the atomization chamber 42 .

For another example, in another alternative embodiment, in addition to the ultrasonic atomizing sheet, the atomizing element 44 can obviously also use commonly used heating elements and other methods, as long as the setting form and setting position of the atomizing element 44 can make The water in the atomizing chamber 42 only needs to generate water mist.

Of course, the above-mentioned alternative embodiments, as well as between the alternative embodiments and the preferred embodiments, can also be used in cross-combination, so that new embodiments can be combined to be suitable for more specific application scenarios.

The control method of the drum washing machine of the present invention will be described below with reference to FIGS. 1 to 10 , wherein FIG. 10 is a flowchart of the control method of the drum washing machine of the present invention.

As shown in Figure 10, the control method of the drum washing machine of the present invention mainly includes:

S100, control the solenoid valve 8 to open, for example, after the related functions such as steam washing are completed, the control unit 9 controls the solenoid valve 8 to open to feed water into the atomizing chamber 42;

S200, when the solenoid valve 8 is opened, control the vibration of the ultrasonic atomizing sheet to detect the height of the liquid level in the atomization chamber 42. For example, when the solenoid valve 8 is opened, the controller 47 controls the driving circuit board 441 to be turned on, and the driving circuit The plate 441 drives the ultrasonic atomizing sheet to work, and the ultrasonic atomizing sheet detects the height of the liquid level in the atomizing chamber 42 through vibration; of course, the timing of the ultrasonic atomizing sheet detection can be adjusted, such as controlling the ultrasonic wave after the solenoid valve 8 is opened for a certain period of time. The atomizing sheet vibrates to detect the height of the liquid level in the atomizing chamber 42 .

S300. Determine whether the height of the liquid level reaches the set height. If the set height is a certain height in the interval higher than the siphon 491 but lower than the height of the gap 4171, when the ultrasonic atomizer detects the height of the liquid level, judge Whether the height of the liquid level reaches the set height;

S400. Based on the judgment result, selectively control the solenoid valve 8 to close, so as to discharge the liquid in the atomizing chamber 42; for example, when the liquid level reaches the set height, it is proved that the siphon has been formed, and the solenoid valve 8 is controlled to close at this time, The liquid in the atomizing cavity 42 will be completely drained under the action of siphon; when the liquid level does not reach the set height, the ultrasonic atomizing sheet continuously detects the height of the liquid level.

Through the above control method, the drum washing machine of the present invention can use the siphon principle generated between the siphon tube 491 and the siphon cap 492 to drain the liquid in the atomization chamber 42, thereby improving the self-cleaning effect of the drum washing machine and ensuring the atomization generator 4 fog effect.

1 to 10 , in a possible implementation manner, the working process of the front-loading washing machine will be described.

In a possible implementation, after the user selects the steam washing option on the control panel of the drum washing machine, the solenoid valve 8 is turned on, water enters the atomization chamber 42, and the ultrasonic atomizer first detects the height of the liquid level, and waits for the liquid After the position reaches the set height, the solenoid valve 8 is closed, the controller 47 controls the drive circuit board 441 and the fan 48 to start at the same time, the ultrasonic atomizing sheet atomizes the water in the atomizing chamber 42, and the fan 48 passes the external air through the inlet. The tuyere 4111 is introduced into the installation cavity 43. After the air flows through the controller 47 to cool the controller 47, it flows into the atomization cavity 42 through the gap 4171, and drives the steam atomized by the ultrasonic atomizing sheet to pass through the first communication hole 4141 and the communication cavity in turn. , the second communication hole 4142, the communication pipe, the mist outlet 4113 and the mist outlet pipe 7, and then sprayed into the inner cylinder 2 to treat the clothes. After the steam washing function is over, the solenoid valve 8 is controlled to open again, water enters the atomization chamber 42, and the ultrasonic atomizer detects whether the liquid level is higher than the set height. When the liquid level reaches the set height, it proves that the siphon has been At this time, the solenoid valve 8 is closed, and the liquid in the atomizing chamber 42 is completely drained under the action of siphon.
