The drum assembly 100 of the laundry treating apparatus according to the embodiment of the present invention may include an inner drum 1, an outer drum 5, a buoyancy member 2, and a magnetism detecting device 3.

Referring to fig. 1, the drum 1 has a laundry placing chamber 113 and a sensing passage 121, and the sensing passage 121 communicates with the laundry placing chamber 113 such that water levels of the laundry placing chamber 113 and the sensing passage 121 are the same. The clothes placing cavity 113 is used for placing clothes, the detecting channel 121 may extend along the up-down direction (see fig. 1), and the invention is not limited thereto, and the detecting channel 121 may also extend along an inclined direction having a certain included angle with the up-down direction, for example, the included angle between the extending direction of the detecting channel 121 and the up-down direction may be 1 °, 2 °, 3 °, 4 °, 5 °, 6 °, 7 °, or 8 °.

Referring to fig. 1 and 2, the buoyant member 2 includes a body 21 and a magnetic member 22, and the buoyant member 2 is configured to float on the surface of water to move in the detection passage 121 according to the height of the water level in the laundry placing chamber 113, and it can be understood that the buoyant member 2 moves up and down along with the surface of the water, and when the surface of the water rises, the buoyant member 2 rises along with the rise of the surface of the water, and when the surface of the water falls, the buoyant member 2 falls along with the fall of the surface of the water, and the height of the surface of the water can be determined by the floating height of the buoyant member 2. For example, the body 21 may be made of a foam material, and the magnetic member 22 may be a magnet.

The magnetic detection device 3 is located outside the inner barrel 1 and is disposed at a predetermined water level, for example, as shown in fig. 1, the magnetic detection device 3 is disposed on the outer barrel 5 and is at the same height as the predetermined water level of the inner barrel 1, and the magnetic detection device 3 is configured to detect a magnetic field signal of the magnetic member 22 to detect whether the magnetic member 22 is at the predetermined water level. It can be understood that the magnetic detection device 3 is in signal communication with a control device (not shown) of the laundry treatment apparatus, so that intelligent control of the water level in the drum 1 can be realized.

For example, as shown in fig. 1 and 2, the laundry treating apparatus is a drum washing machine, and when washing starts, the inner tub 1 is rotated to a first position, in the first position, the buoyancy member 2 is located at the lowermost end of the inner cylinder 1, and the detection passage 121 extends in the up-and-down direction, and then the laundry is placed in the inner cylinder 1, then the water inlet valve 6 of the clothes treatment device is controlled to feed water into the inner drum 1, the buoyancy element 2 rises along with the rise of the liquid level in the inner drum 1, when the magnetism detection device 3 detects that the magnetic field signal of the buoyancy member 2 reaches the strongest by detecting the magnetic member 22, the buoyancy member 2 floats to reach the same level as the magnetic detection device 3, at this time, the magnetic detection device 3 transmits the signal to the control device of the clothes treatment device, the control device judges that the water level in the inner barrel 1 reaches the preset water level, and the control device controls the water inlet valve 6 to stop adding water, so that the water level in the inner barrel 1 is controlled to be the preset water level.

However, since the washing machine itself is not accurately weighed, it is difficult to control the water level of the laundry with different qualities, and since the water absorption of the laundry with different materials is different, the related art laundry treatment apparatus cannot ensure that the water level in the inner tub is at the preset water level.

According to the barrel assembly 100 of the clothes treatment device provided by the embodiment of the invention, the floating height of the buoyancy element 2 is changed in real time along with the height of the water level in the inner barrel 1, and the magnetic detection device 3 is used for detecting the magnetic field signal of the magnetic element 22 to detect whether the magnetic element 22 is at the preset water level, so that the magnetic detection device 3 can accurately detect whether the water level in the inner barrel 1 reaches the preset water level, the accuracy of water level detection can be improved, the barrel assembly can be suitable for performing water level detection on clothes with different qualities and different water absorptions, and the water level in the inner barrel 1 can be ensured to accurately reach the preset water level, thereby solving the problems of inaccurate weighing and different water absorptions of different fabrics, being beneficial to ensuring the cleaning effect of the clothes treatment device and improving the working efficiency.
