During the drying process of the laundry treatment device, the water inlet valve 7 may open to let water in, and the external condensed water can enter the interior of the outer tub 2 through the water inlet valve 7, the first interface 811, the water delivery channel 813, the second interface 812, and the water inlet hole 22.

[0079] In some embodiments, a third interface 821 may be provided inside the three-way pipe 8. The third interface 821 may be disposed above the water delivery channel 813. The third interface 821 may be connected to one end of the pressure balance pipe 6 close to the outer tub 2. During the washing process of the laundry treatment device, the interior space of the outer tub 2 can be connected to the external space through the water inlet hole 22, the second interface 812, the third interface 821, the pressure balance pipe 6, and the water inlet box 4.

[0080] In some embodiments, the three-way pipe 8 may include a horizontal pipe 81 and a vertical pipe 82. The horizontal pipe 81 may be horizontally extended in the front-rear direction. The vertical pipe 82 may be extended upward from the top of the horizontal pipe 81. The interior of the horizontal pipe 81 and the interior of the vertical pipe 82 may be connected.

[0081] In some embodiments, the first interface 811 may be disposed at one end of the horizontal pipe 81 away from the outer cylinder 2. The second interface 812 may be disposed at one end of the horizontal pipe 81 close to the outer cylinder 2. The third interface 821 may be disposed at the upper end of the vertical pipe 82.

[0082] Please refer to Figures 2 to 4 As shown, in some embodiments, a second water inlet pipe 71 may be provided between the water inlet valve 7 and the third water inlet pipe 23. The second water inlet pipe 71 may be disposed between the water inlet valve 7 and the first interface 811. One end of the second water inlet pipe 71 may be communicated with the water inlet valve 7. The other end of the second water inlet pipe 71 may be communicated with the first interface 811. During the drying process of the laundry treatment device, the water inlet valve 7 may be opened, and external condensed water can enter the interior of the outer cylinder 2 through the water inlet valve 7, the second water inlet pipe 71, the first interface 811, the water delivery channel 813, the second interface 812, and the water inlet hole 22.

[0083] In some embodiments, a third water inlet pipe 23 may be provided at the water inlet hole 22. The third water inlet pipe 23 may be disposed between the water inlet hole 22 and the second interface 812. One end of the third water inlet pipe 23 may be communicated with the water inlet hole 22. The other end of the third water inlet pipe 23 may be communicated with the water inlet valve 7. During the drying process of the laundry treatment device, the water inlet valve 7 may be opened, and external condensed water can enter the interior of the outer cylinder 2 through the water inlet valve 7, the second water inlet pipe 71, the first interface 811, the water delivery channel 813, the second interface 812, the third water inlet pipe 23, and the water inlet hole 22.

[0084] It should be noted that in some other embodiments, the laundry treatment device may not be provided with the third water inlet pipe 23. The laundry treatment device may not be provided with the second water inlet pipe 71.

[0085] Please refer to Figures 2 to 10 As shown, in some embodiments, a float 9 may be provided inside the water delivery channel 813. The float 9 is movably disposed up and down in the water delivery channel 813. During the laundry drying process, the water inlet valve 7 may be opened, and external condensed water can enter the water delivery channel 813 from the water inlet valve 7. The float 9 may be disposed below the third interface 821, and the water level in the water delivery channel 813 can rise, so that the float 9 can move upward with the rise of the water level to block the third interface 821. By blocking the third interface 821 during the drying process, it is possible to prevent the hot and humid air in the laundry treatment chamber 31 from entering the pressure balance pipe 6 through the third interface 821, thereby reducing the heat loss in the laundry treatment chamber 31. At the same time, by blocking the third interface 821 during the drying process, it is possible to prevent the formation of condensed water in the pressure balance pipe 6 by the hot and humid air, thereby preventing the condensed water from flowing out of the laundry treatment device and affecting the user experience.

[0086] In some embodiments, the water delivery channel 813 can be circular. The float 9 can be spherical. Since a sphere has no edges or corners, this reduces the friction between the float 9 and the inner wall of the water delivery channel 813, thus ensuring the smooth up and down movement of the float 9.

[0087] It should be noted that, in some other embodiments, the float 9 can be a regular polyhedron. The float 9 can be a cube.

[0088] In some embodiments, a vent hole 814 can be formed in the top wall of the water delivery channel 813. The vent hole 814 can communicate the third interface 821 and the water delivery channel 813. During the clothes drying process, the water inlet valve 7 can be opened, and external condensed water can enter the water delivery channel 813 from the water inlet valve 7. The float 9 can be disposed below the vent hole 814, and the water level in the water delivery channel 813 can rise, so that the float 9 can move upward with the rising water level to block the vent hole 814, thereby blocking the third interface 821 by blocking the vent hole 814.

[0089] In some embodiments, the size of the vent hole 814 can be smaller than the size of the third interface 821, so that when the float 9 rises, it can more easily block the vent hole 814.

[0090] Please refer to Figures 4 to 10 As shown, in some embodiments, a blocking member 815 can be provided in the water delivery channel 813. The blocking member 815 can be disposed on one side close to the second interface 812 below the third interface 821. When the water inlet valve 7 is opened to let water in, the water flow of the condensed water can drive the float 9 to abut against the blocking member 815. At this time, the float 9 can be located below the third interface 821. The blocking member 815 can limit the float 9, so that when the water inlet valve 7 is opened to let water in, the float 9 can be located below the third interface 821.

[0091] In some embodiments, a water passing hole 8151 can be formed in the blocking member 815. The water passing hole 8151 can communicate the first interface 811 and the second interface 812. When the water inlet valve 7 is opened to let water in, the condensed water can flow into the interior of the outer cylinder 2 through the water inlet valve 7, the first interface 811, the water passing hole 8151, the second interface 812, and the water inlet hole 22.

[0092] In some embodiments, the water passing hole 8151 can be disposed at the lower end of the blocking member 815, so that the condensed water passing through the water inlet valve 7 can more easily enter the interior of the outer cylinder 2 through the water passing hole 8151.

[0093] It should be noted that, in some other embodiments, the water passing hole 8151 can be disposed at the upper end or other positions of the blocking member 815.

[0094] It should be noted that in some other embodiments, there may be multiple water passing holes 8151. When the water inlet valve 7 opens to let water in, the condensed water can pass through the water inlet valve 7 and the first interface 811 and then simultaneously pass through multiple water passing holes 8151, the second interface 812, and the water inlet hole 22 to flow into the interior of the outer cylinder 2. Furthermore, through the multiple water passing holes 8151, the flow efficiency of the condensed water flowing from the first interface 811 to the second interface 812 can be improved.

[0095] In some embodiments, during the clothes drying process, the water inlet valve 7 can open to let water in, and the water inlet speed of the condensed water at the water inlet valve 7 can be greater than the water outlet speed at the water passing holes 8151. As a result, the water level in the water delivery channel 813 near the first interface 811 can rise, and then the float 9 can be driven to move upward so that the float 9 can block the ventilation hole 814.

[0096] Please refer to Figures 4 to 10 As shown, in some embodiments, a contact surface 8152 can be provided on one side of the blocking member 815 close to the float 9. The contact surface 8152 can be inclined and extend downward in the direction towards the float 9. When the water inlet valve 7 opens to let water in, the float 9 can be abutted against the contact surface 8152 under the impact of the water flow and can move upward along the bottom cross-section as the water level rises, so that the float 9 blocks the third interface 821. Through the inclined setting of the contact surface 8152, it is easier for the float 9 to rise along the contact surface 8152.

[0097] In some embodiments, the blocking member 815 can include a second extension portion 8154. The second extension portion 8154 is inclined and extends downward in the direction towards the float 9. The contact surface 8152 can be provided on one side of the second extension portion 8154 close to the float 9. When the water inlet valve 7 opens to let water in, the float 9 can be abutted against the second extension portion 8154 under the impact of the water flow and can move upward along the bottom cross-section as the water level rises, so that the float 9 blocks the third interface 821. Through the inclined setting of the contact surface 8152, it is easier for the float 9 to rise along the contact surface 8152.

[0098] In some embodiments, the side wall of the second extension portion 8154 can be hermetically connected to the side wall of the water delivery channel 813 so that the blocking portion can be stably arranged inside the water delivery channel 813.

[0099] In some embodiments, the blocking member 815 can include a first extension portion 8153. The first extension portion 8153 can be arranged above the second extension portion 8154. The first extension portion 8153 can extend upward from the top end of the second extension portion 8154. The top end of the first extension portion 8153 is hermetically connected to the top wall of the water delivery channel 813.

[0100] In some embodiments, the blocking member 815 may include a third extension portion 8155. The third extension portion 8155 may be disposed below the second extension portion 8154. The third extension portion 8155 may extend downward from the lower end of the second extension portion 8154. The lower end of the third extension portion 8155 may be sealingly connected to the bottom wall of the water delivery channel 813.

[0101] In some embodiments, the water passing holes 8151 may be disposed on the third extension portion 8155. The water passing holes 8151 may be disposed at the bottom end of the third extension portion 8155.

[0102] It should be noted that, in some other embodiments, the water passing holes 8151 may be disposed on the second extension portion 8154. The water passing holes 8151 may be disposed on the first extension portion 8153.

[0103] Please refer to Figures 4 to 10 As shown, in some embodiments, a limiting rib 816 may be provided in the water delivery channel 813. The limiting rib 816 may protrude upward from the bottom wall of the water delivery channel 813. The limiting rib 816 may be located on the side close to the first interface 811 below the third interface 821. When the water inlet valve 7 is closed and no water enters, the float 9 can be limited between the limiting rib 816 and the blocking rib, thereby preventing the float 9 from detaching from the water delivery channel 813.

[0104] In some embodiments, the height of the limiting rib 816 is less than the difference between the diameter of the water delivery channel 813 and the diameter of the float 9, so that the float 9 can be installed into the water delivery channel 813 from the first interface 811.

[0105] From the above technical solutions, it can be seen that the embodiments of the present utility model have at least the following advantages and positive effects:

[0106] The present utility model provides a clothing treatment device. The housing 1 is the external shell of the clothing treatment device. Inside the housing 1, a drum assembly is provided. The drum assembly includes an inner drum 3 and an outer drum 2. Inside the inner drum 3, a clothing treatment cavity 31 is provided. On the outer wall of the outer drum 2, a water inlet hole 22 communicating with the inside of the outer drum 2 is provided. One end of a pressure balance pipe 6 communicates with the external space, and the other end communicates with a third interface 821 of a tee pipe 8. One end of a water inlet valve 7 communicates with an external water source, and the other end communicates with a first interface 811 of the tee pipe 8. A connecting pipe communicates with a second interface 812 of the tee pipe 8. The third interface 821, the first interface 811, and the second interface 812 communicate with each other. Inside the tee pipe 8, a water delivery channel 813 communicating the first interface 811 and the second interface 812 is provided. The water delivery channel 813 communicates with the third interface 821 and is disposed below the third interface 821. Inside the water delivery channel 813, a float 9 is provided. The float 9 is capable of moving up and down inside the water delivery channel 813. During the clothing drying process, the water inlet valve 7 can admit water. The float 9 can be disposed below the third interface 821. The water level inside the water delivery channel 813 can rise, enabling the float 9 to move upward as the water level rises, so that the float 9 can block the third interface 821, and the water inside the water delivery channel 813 can provide condensed water to the inside of the outer drum 2 through the water inlet hole 22. By blocking the third interface 821 during the drying process, it is possible to prevent the hot and humid air inside the clothing treatment cavity 31 from entering the pressure balance pipe 6 through the third interface 821, and thus reduce the heat loss inside the clothing treatment cavity 31. At the same time, by blocking the third interface 821 during the drying process, it is possible to prevent condensed water from forming in the pressure balance pipe 6 due to the hot and humid air, and thus avoid the condensed water flowing out of the external part of the clothing treatment device, and further avoid affecting the user experience.
