[0079] See also Figures 8 to 13 As shown, in some embodiments, the heating element 5 can be arranged at one end of the lower air duct shell 35 close to the connecting pipe 7, so that the hot air heated by the heating element 5 can be directly blown into the clothing processing chamber 21 through the connecting pipe 7.

[0080] In some embodiments, the heating element 5 is disposed at one end of the lower air duct shell 35 close to the connecting pipe 7, so that there can be a gap between the end of the upper air duct shell 34 protruding out of the lower air duct shell 35 and the heating element 5, thereby reducing the heat received by the inner wall of the connection between the connecting pipe 7 and the upper air duct shell 34, thereby preventing the inner wall of the connection between the connecting pipe 7 and the upper air duct shell 34 from being deformed by heat.

[0081] See also Figures 4 to 13 As shown, in some embodiments, a heat insulating portion 37 may be provided at one end of the air duct assembly 3 near the connecting pipe 7.

The heat insulating portion 37 may be attached to the inner wall of the connecting pipe 7. The heat insulating portion 37 can cover part of the inner wall of the connecting pipe 7. When the heating element 5 is working, the heat insulating portion 37 can prevent the heat on the heating element 5 from being transferred to the inner wall of the connecting pipe 7 near the air duct assembly 3, thereby preventing the inner wall of the connecting pipe 7 from being deformed by heat, thereby preventing the sealing of the air supply duct 31 from being affected, thereby ensuring the drying efficiency of the clothing processing device.

[0082] In some embodiments, the insulation portion 37 can be extended from one end of the down duct shell 35 close to the connecting pipe 7 toward the interior of the connecting pipe 7, so that the insulation portion 37 can cover the inner wall of the connecting pipe 7 close to the down duct shell 35, and further enable the insulation portion 37 to insulate the inner wall of the connecting pipe 7 close to the down duct shell 35.

[0083] It should be noted that, in some other embodiments, the heat insulating portion 37 may be arranged to extend from one end of the upper air duct shell 34 close to the connecting pipe 7 toward the inside of the connecting pipe 7 .

[0089] See also Figures 9 to 13 As shown, in some embodiments, a clamping portion 72 may be protruded from the inner wall of the connecting pipe 7 at one end close to the air duct assembly 3. When the heat insulating portion 37 extends into the connecting pipe 7, the heat insulating portion 37 may be clamped at the clamping portion 72, thereby allowing the heat insulating portion 37 to be attached to the inner wall of the connecting pipe 7.

[0090] In some embodiments, a clamping groove 73 may be formed between the clamping portion 72 and the inner wall of the connecting tube 7. When the heat insulating portion 37 extends into the connecting tube 7, the heat insulating portion 37 may be clamped in the clamping groove 73. The clamping of the heat insulating portion 37 by the clamping groove 73 can improve the stability of the heat insulating portion 37 attached to the inner wall of the connecting tube 7.

[0091] In some embodiments, the clamping portion 72 may be a clamping rib. The clamping rib may be extended upward from the inner wall of the connecting tube 7. A clamping groove 73 is formed between the clamping rib and the inner wall of the connecting tube 7. When the heat insulating portion 37 extends into the connecting tube 7, the heat insulating portion 37 may be clamped in the clamping groove 73.

[0092] See also Figures 2 to 13As shown, in some embodiments, the connecting pipe 7 can be arranged to extend upwardly and obliquely from the upper side of the door seal 22. The heat insulating portion 37 can be arranged to extend downwardly and obliquely from one end of the lower air duct shell 35 close to the connecting pipe 7 toward the inside of the connecting pipe 7. The inclination direction of the heat insulating portion 37 can be the same as the inclination direction of the inner wall of the connecting pipe 7, so that the heat insulating portion 37 can be attached to the inner wall of the connecting pipe 7, thereby avoiding the heat insulating portion 37 from occupying the space inside the connecting pipe 7 and avoiding affecting the air circulation efficiency in the connecting pipe 7.

[0093] In some embodiments, the insulation portion 37 can be plate-shaped so that the insulation portion 37 can completely cover the inner wall of the connecting pipe 7 close to the downwind duct shell 35, thereby increasing the coverage rate of the inner wall of the connecting pipe 7 and preventing the inner wall of the connecting pipe 7 from being deformed due to heating by the heating element 5.

[0094] See also Figures 4 to 13 As shown, in some embodiments, a mounting groove 74 extending toward the lower air duct shell 35 may be provided at the end of the connecting pipe 7 away from the air inlet 23.

[0095] In some embodiments, when the end of the lower air duct shell 35 close to the connecting pipe 7 is installed in the installation groove 74, the heat insulating portion 37 extends into and is attached to the inner wall of the connecting pipe 7. The lower air duct shell 35 and the heat insulating portion 37 can insulate the groove wall of the installation groove 74 to prevent the groove wall of the installation groove 74 from being heated by the heating element 5 and deformed.

[0096] In some embodiments, a limiting groove 75 may be provided on the bottom wall of the installation groove 74. The limiting groove 75 may be formed by the bottom wall of the installation groove 74 being recessed downward.

When the end of the lower air duct shell 35 close to the connecting pipe 7 is installed in the installation groove 74, the limiting rib 38 can extend into the limiting groove 75 and be limited, thereby improving the installation accuracy of the lower air duct shell 35 and the connecting pipe 7.

[0097] In some embodiments, a mounting groove 77 may be provided on the top surface of the side wall of the mounting groove 74. The mounting groove 77 may be formed by the top surface of the side wall of the mounting groove 74 being recessed downward. The mounting groove 77 may be connected to the mounting groove 74. The edge of the end of the downwind shell 35 close to the connecting pipe 7 may be assembled in the mounting groove 77, thereby positioning the installation position of the downwind shell 35 and the connecting pipe 7, and improving the connection stability of the downwind shell 35 and the connecting pipe 7.

[0098] In some embodiments, the edge of the peripheral side wall of the lower air duct shell 35 is bent outward to extend with a first extension rib 351. When the lower air duct shell 35 is connected to the end of the connecting pipe 7 away from the air inlet 23, the first extension rib 351 can be assembled in the assembly groove 77, thereby positioning the installation position of the lower air duct shell 35 and the connecting pipe 7, and improving the connection stability of the lower air duct shell 35 and the connecting pipe 7.

[0099] In some embodiments, the circumferential edge of the upper air duct shell 34 is provided with a second extension rib 341 that bends and extends outward. When the upper air duct shell 34 is covered on the upper part of the lower air duct shell 35, the second extension rib 341 can be arranged vertically opposite to the first extension rib 351, and the second extension rib 341 can be sealed against the first extension rib 351 to improve the sealing between the upper air duct shell 34 and the lower air duct shell 35.

[0100] In some embodiments, a sealing groove 76 may be recessed downward at the end of the connecting pipe 7 away from the air inlet 23. The sealing groove 76 may be arranged around the end of the connecting pipe 7 away from the air inlet 23. A sealing strip 761 may be provided in the sealing groove 76. The sealing strip 761 may be covered in the sealing groove 76 at one end of the upper air duct shell 34 close to the connecting pipe 7, so that the upper air duct shell 34 and the connecting pipe 7 can be sealed and connected, thereby preventing the air of the air supply duct 31 from leaking between the upper air duct shell 34 and the connecting pipe 7.

[0101] In some embodiments, the circumferential edge of the upper air duct shell 34 may be provided with a third extension rib 342 that bends and extends outward. The third extension rib 342 may be connected to the second extension rib 341. When the upper air duct shell 34 is covered on the lower air duct shell 35, the third extension rib 342 may protrude from one end of the lower air duct shell 35.
