[0021] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0022] In related technologies, a garment processing device may include at least two washing tubs of different capacities. After the garments are washed in the smaller washing tub (the first tub), hot air may be supplied to the first tub to dry the garments inside.

[0023] The garment processing apparatus 100 according to an embodiment of the present disclosure is described below with reference to the accompanying drawings. As shown in Figures 1-5, the garment processing apparatus 100 according to an embodiment of the present disclosure includes a housing (not shown), an upper suspension beam 2, a first tub 3, a drying duct 4, and a fan 5. The first tub 3 has a first air inlet 31 and a first air outlet. The drying duct 4 has a second air inlet 411 and a second air outlet 412. The outlet 51 of the fan 5 is connected to the second air inlet 411 of the drying duct 4, and the second air outlet 412 of the drying duct 4 is connected to the first air inlet 31 of the first tub 3. The upper suspension beam 2 is connected to the housing, the drying duct 4 is connected to the upper suspension beam 2, the drying duct 4 is connected to the first tub 3, and the fan 5 is connected to the drying duct 4.

[0024] The garment processing apparatus 100 according to an embodiment of the present disclosure connects the drying duct 4 to both the upper suspension beam 2 and the first drum 3, thereby enabling a more stable installation of the drying duct 4 without the need for additional installation structures. The garment processing apparatus 100 according to an embodiment of the present disclosure connects the fan 5 to the drying duct 4, eliminating the need for additional structures for installing the fan 5, thus simplifying the structure of the garment processing apparatus 100 and reducing manufacturing costs.

[0025] Therefore, the garment processing apparatus 100 according to the embodiments of this disclosure has advantages such as stable structure, simple structure, and low manufacturing cost.

[0026] As shown in Figures 1-5, the garment processing apparatus 100 according to an embodiment of the present disclosure includes a housing, an upper suspension beam 2, a first tub 3, a drying air duct 4, and a fan 5. Those skilled in the art will understand that the garment processing apparatus 100 may further include a second tub, which may be located below the first tub 3. In some embodiments, the second tub can be used for washing or processing large garments, while the first tub 3 can be used for washing or processing small garments (e.g., underwear, children's clothing).

[0027] In this configuration, the volume of the first bucket 3 is generally no greater than the volume of the second bucket. This can also be understood as the external dimensions of the first bucket 3 being no greater than the external dimensions of the second bucket. In some embodiments, the first bucket 3 can be understood as a smaller bucket, and the second bucket as a larger bucket.

[0028] The housing includes a first side plate, a second side plate, a third side plate, and a fourth side plate. The first side plate and the second side plate are arranged opposite each other in the length direction of the housing (clothing handling device 100), and the third side plate and the fourth side plate are arranged opposite each other in the width direction of the housing (clothing handling device 100).

[0029] In some embodiments, the length direction of the housing (clothing handling device 100) is consistent with the left-right direction, the width direction of the housing (clothing handling device 100) is consistent with the front-back direction, and the height direction of the housing (clothing handling device 100) is consistent with the up-down direction. The left-right direction is shown by arrow A in Figure 1, and the front-back direction is shown by arrow B in Figures 1-5.

[0030] The first tub 3 is located inside the housing. The first tub 3 is adjacent to the upper suspension beam 2 in the height direction of the housing (clothing handling device 100), and is located below the upper suspension beam 2. In some embodiments, the upper suspension beam 2 is rigidly connected to the housing. This allows for a more secure installation of the drying duct 4.

[0031] The upper part of the first side plate has an inwardly extending first flange, and the upper part of the second side plate has an inwardly extending second flange. The upper suspension beam 2 has a first end 21 and a second end 22 opposite to each other in the length direction of the housing. The first end 21 is connected to the first flange by a threaded fastener, and the second end 22 is connected to the second flange by a threaded fastener. This allows the upper suspension beam 2 to be connected to the housing more conveniently and more securely.

[0032] In some embodiments, the first side panel is located to the left of the second side panel, the first flange extends to the right from the first side panel, and the second flange extends to the left from the second side panel.

[0033] As shown in Figures 2-5, the drying duct 4 includes a duct section 42 and a mounting section 43. The duct section 42 has a second air inlet 411 and a second air outlet 412, and is connected to the first barrel 3. The mounting section 43 is provided on the duct section 42 and is connected to each of the upper suspension beam 2 and the fan 5. By including the duct section 42 and the mounting section 43 in the drying duct 4, drying gas is conveyed into the first barrel 3 using the duct section 42, and the drying duct 4 is mounted to the upper suspension beam 2 and the fan 5 is mounted to the drying duct 4 using the mounting section 43, thus making the structure of the drying duct 4 more reasonable.

[0034] As shown in Figures 2 and 4, a portion 431 of the mounting part 43 extends out of the air duct part 42 along the length direction of the first barrel 3, and this portion 431 is connected to the fan 5. By having a portion 431 of the mounting part 43 extend out of the air duct part 42, it is easier and more convenient to connect the fan 5 to the portion 431 of the mounting part 43. In some embodiments, the length direction of the first barrel 3 is consistent with the width direction (front-back direction) of the casing.

[0035] In some embodiments, a portion 432 of the mounting part 43 located in the air duct part 42 is connected to the upper suspension beam 2 via threaded fasteners, and a portion 431 of the mounting part 43 is also connected to the upper suspension beam 2 via threaded fasteners. This allows for a more convenient and stable installation of the drying air duct 4 onto the upper suspension beam 2, enabling the drying air duct 4 to better bear the weight of the fan 5. A portion 431 of the mounting part 43 is connected to the fan 5 via threaded fasteners. This allows for a more convenient and stable installation of the fan 5 into the drying air duct 4.

[0036] As shown in Figures 3 and 5, the outlet end 52 of the fan 5 has an outlet 51, and the air inlet end 423 of the air duct section 42 has a second air inlet 411. The outlet end 52 of the fan 5 extends into the air duct section 42 through the second air inlet 411. Alternatively, the air inlet end 423 of the air duct section 42 extends into the outlet end 52 of the fan 5 through the outlet 51. This allows all the air discharged from the fan 5 to enter the air duct section 42 and then into the first drum 3, thereby increasing the drying speed and shortening the garment processing time.

[0037] In some embodiments, a seal is provided between the outlet end 52 of the fan 5 and the inner wall surface of the air duct 42, or a seal is provided between the air inlet end 423 of the air duct 42 and the inner wall surface of the outlet end 52 of the fan 5. This effectively prevents air leakage at the joint between the air duct 42 and the fan 5, thereby further improving the drying speed and further shortening the garment processing time.

[0038] As shown in Figures 2-5, the air duct section 42 includes a first air duct section 421 and a second air duct section 422. The first air duct section 421 extends along the length of the first barrel 3 and has a second air inlet 411. The mounting part 43 is provided on the first air duct section 421.

[0039] The second air duct section 422 includes a first part 4221 and a second part 4222, which are connected. The first part 4221 extends along the length of the first barrel 3 and is connected to the first air duct section 421. The second part 4222 extends along the inward and outward directions of the first barrel 3, and has a second air outlet 412, which is also connected to the first barrel 3. In some embodiments, the second air duct section 422 is L-shaped. This makes the structure of the air duct section 42 more reasonable.

[0040] In some embodiments, the first portion 4221 and the second portion 4222 are integrally formed. This allows for a more rational structure of the air duct section 42 and reduces the manufacturing difficulty of the second air duct section 422 (air duct portion 42). The second portion 4222 extends radially along the first barrel 3.

[0041] In some embodiments, the first air duct section 421 and the second air duct section 422 are detachably connected. The first air duct section 421 has a third air outlet, and the first part 4221 has a third air inlet, which communicates with the third air outlet. This reduces the manufacturing difficulty of the air duct section 42 and makes the structure of the air duct section 42 more reasonable.

[0042] In some embodiments, the first air duct section 421 and the second air duct section 422 are detachably connected by threaded fasteners. In some embodiments, the first air duct section 421 and the first portion 4221 of the second air duct section 422 are connected by threaded fasteners. This makes it easier and more secure to connect the first air duct section 421 and the second air duct section 422, thereby making the structure of the air duct section 42 (drying air duct 4) more stable.

[0043] As shown in Figures 3 and 5, the garment handling device 100 further includes a heating element 44, which is disposed within the air duct section 42 and located at the connection between the first air duct section 421 and the second air duct section 422. Since the first air duct section 421 and the second air duct section 422 are detachably connected, placing the heating element 44 at the connection reduces the difficulty of installation and replacement, thus facilitating maintenance of the heating element 44.

[0044] Specifically, the heating element 44 may be entirely located within the first air duct section 421 and adjacent to the second air duct section 422, or it may be entirely located within the second air duct section 422 and adjacent to the first air duct section 421. Alternatively, a portion of the heating element 44 may be located within the first air duct section 421, and the remaining portion may be located within the second air duct section 422. In some embodiments, the heating element 44 may be a PTC heater.

[0045] The length of the first air duct section 421 is greater than or equal to 65 mm and less than or equal to 79 mm. The second air inlet 411 and the third air outlet are both rectangular openings. The length of the second air inlet 411 is less than the length of the third air outlet, and the width of the second air inlet 411 is greater than the width of the third air outlet.

[0046] By making the second air inlet 411 have a larger width and a smaller length, the second air inlet 411 of the first air duct section 421 (air duct part 42) can be better matched with the outlet 51 of the fan 5. By making the third air outlet have a larger length and a smaller width, the third air outlet of the first air duct section 421 can be better matched with the heating element.

[0047] In some embodiments, the length of the second air inlet 411 is greater than or equal to 60 mm and less than or equal to 65 mm, and the width of the second air inlet 411 is greater than or equal to 35 mm and less than or equal to 40 mm. The length of the third air outlet is greater than or equal to 90 mm and less than or equal to 100 mm, and the width of the third air outlet is greater than or equal to 22 mm and less than or equal to 28 mm.

[0048] As shown in Figures 2 and 3, in one embodiment of this disclosure, a first air inlet 31 is located on the circumferential surface 332 of the front end portion 331 of the first tub 3, and a first air outlet is located on the end face 334 and / or circumferential surface of the rear end portion 333 of the first tub 3. In some embodiments, the first air outlet is located on the end face 334 of the rear end portion 333 of the first tub 3. This allows drying gas to enter the front end portion 331 of the first tub 3 from the first air inlet 31, and then the drying gas flows from front to back within the first tub 3 to heat and dry the clothes inside. The drying gas carrying moisture is then discharged from the rear end portion 333 of the first tub 3.

[0049] In some embodiments, the fan 5 is adjacent to the rear end 333 of the first barrel 3 in the front-rear direction (width direction of the casing). The first air duct section 421 is located in front of the fan 5, and the third air outlet of the first air duct section 421 is located in front of the second air inlet 411 of the first air duct section 421. The second air duct section 422 is located in front of the first air duct section 421, and the second part 4222 is located in front of the first part 4221. The second air outlet 412 of the second part 4222 (second air duct section 422) is adjacent to the front end 331 of the first barrel 3 in the front-rear direction.

[0050] As shown in Figure 3, the first bucket 3 includes a bucket body 34 and an air intake section 35. A first air inlet 31 is located on the circumferential surface of the front end of the bucket body 34. The air intake section 35 extends in the inward and outward directions of the first bucket 3, and has a fourth air inlet 351 and a fourth air outlet 352. In some embodiments, the air intake section 35 extends radially along the first bucket 3. The outer end of the air intake section 35 is connected to the second portion 4222 so that the fourth air inlet 351 communicates with the second air outlet 412, and the inner end of the air intake section 35 is connected to the circumferential surface of the front end of the bucket body 34 so that the fourth air outlet 352 communicates with the first air inlet 31.

[0051] Because the circumferential surface of the front end of the barrel 34 is curved (in some embodiments, the circumferential surface is cylindrical), the second part 4222 of the drying duct 4 is not easily directly connected to the circumferential surface of the front end of the barrel 34. By including the air intake 35 in the first barrel 3 and connecting the second part 4222 of the drying duct 4 to the circumferential surface of the front end of the barrel 34 through the air intake 35, the drying duct 4 can be connected to the first barrel 3 more conveniently and easily.

[0052] As shown in Figures 4 and 5, in another embodiment of this disclosure, a first air inlet 31 is located on the end face 334 and / or circumferential surface of the rear end portion 333 of the first tub 3, and a first air outlet is located on the circumferential surface 332 of the front end portion 331 of the first tub 3. In some embodiments, the first air inlet 31 is located on the end face 334 of the rear end portion 333 of the first tub 3. This allows drying gas to enter the rear end portion 333 of the first tub 3 from the first air inlet 31, and then the drying gas flows from back to front within the first tub 3 to heat and dry the clothes inside the first tub 3. The drying gas carrying moisture is then discharged from the front end portion 331 of the first tub 3.

[0053] In some embodiments, the fan 5 is adjacent to the front end portion 331 of the first barrel 3 in the front-rear direction (width direction of the casing). The first air duct section 421 is located behind the fan 5, and the third air outlet of the first air duct section 421 is located behind the second air inlet 411 of the first air duct section 421. The second air duct section 422 is located behind the first air duct section 421, and the second portion 4222 is located behind the first portion 4221. The second air outlet 412 of the second portion 4222 (second air duct section 422) is adjacent to the rear end portion 333 of the first barrel 3 in the front-rear direction.

[0054] As shown in Figure 5, the first bucket 3 includes a bucket body 34 and an air intake section 35, with a first air inlet 31 located on the end face of the rear end portion of the bucket body 34. The air intake section 35 includes a third portion 353 and a fourth portion 354. The third portion 353 extends along the inward and outward directions of the first bucket 3 and has a fourth air inlet 351. In some embodiments, the third portion 353 extends radially along the first bucket 3. The fourth portion 354 extends along the length direction of the first bucket 3 and has a fourth air outlet 352.

[0055] The outer end of the third part 353 is connected to the second part 4222 so that the fourth air inlet 351 communicates with the second air outlet 412. The inner end of the third part 353 is connected to one end of the fourth part 354, and the other end of the fourth part 354 is connected to the end face of the rear end portion of the barrel 34 so that the fourth air outlet 352 communicates with the first air inlet 31. In some embodiments, the air duct 35 is L-shaped.

[0056] By including an L-shaped air intake 35 in the first barrel 3, the second part 4222 of the drying air duct 4, which extends in the inward and outward directions of the first barrel 3, can be more conveniently and easily connected to the end face of the rear end of the barrel body 34.

[0057] In some embodiments, the barrel body 34 and the air intake section 35 are integrally formed. This makes the structure of the first barrel 3 more reasonable and reduces the manufacturing difficulty and cost of the first barrel 3. The air intake section 35 is connected to the second part 4222 by threaded fasteners. This makes it easier and more secure to connect the air intake section 35 and the second air duct section 422.
