In addition, the liquid level monitoring device 2 may be any type of sensor or other device having a detection function, such as a liquid level sensor and a radar sensor, which is not particularly limited in this embodiment.

Since the first tub is drained, the water in the first drainage chamber 5 does not enter the second drainage chamber 6 under normal conditions, but is directly drained from the water outlet 13. Therefore, in the case of an excessive displacement, a water signal is generated once the liquid level monitoring device 2 detects the presence of water in the second drainage chamber 6. At this time, the controller or the user can find the water-crossing phenomenon according to the water-crossing signal, so that the water-crossing phenomenon is treated in time, and when the first barrel is drained, water is not easy to cross into the second barrel, the normal use of the second barrel is ensured, and the drainage quality is improved.

8. The laundry treatment apparatus of claim 6, wherein the controller is configured to:

in response to a status signal of the laundry treatment apparatus, when the status signal characterizes that the first tub is in a draining state and the second tub is not in a draining state, controlling the liquid level monitoring device (2) to detect whether water is present in the second draining chamber.

9. The laundry treatment apparatus according to claim 8, characterized in that when a second probe in the liquid level monitoring device (2) detects that there is water in the second drain chamber and a first probe detects that there is water in the first drain chamber, an electrical connection line between the first and second probes and the controller is conducted, so that signals transmitted by the first and second probes form the water signal.

10. The laundry treatment apparatus of claim 6, wherein the controller is configured to:

when the water signal is received, judging whether the state signal represents that the first barrel is in a drainage state and the second barrel is not in the drainage state;

if yes, judging that the water flowing condition is met;

otherwise, judging that the water flowing condition is not met,

or alternatively, the first and second heat exchangers may be,

the controller is configured to:

when the water signal is received, judging whether the state signal represents that the first barrel is in a drainage state and the second barrel is not in the drainage state;

if yes, judging whether the water level value of the second water discharge cavity in the water signal exceeds a preset water level threshold value;

if the water level threshold value is exceeded, judging that the water flowing condition is met;

and if the first barrel is not in the drainage state or the second barrel is in the drainage state or the water level value does not exceed the water level threshold value, judging that the water flowing condition is not met.

11. Laundry treatment apparatus according to any of claims 5-10, characterized in that the first tub is located above the second tub, the second water inlet (12) being provided with a drain pump (4) for guiding water in the second tub into the second drain chamber.

12. Laundry treatment apparatus according to any of claims 5-10, characterized in that the baffle (7) is closer to the second water inlet (12) than the first water inlet (11).

13. A drain control method applied to the laundry treating apparatus according to any one of claims 5 to 12, comprising:

acquiring a state signal of the clothes treatment equipment in response to a water signal output by a liquid level monitoring device (2) in the drain box assembly;

when the water signal and the state signal meet the water-flowing condition, the water draining mode of the first barrel is changed into intermittent water draining mode.
