[0036] Example 1

[0037] An embodiment of the present application provides a condensing air duct assembly, which is used for application on a clothing processing device, which is a clothing processing device with a drying function, such as a washer-dryer.

[0038] For ease of understanding, Figure 1As shown, the clothing processing device includes an outer drum 1 and an inner drum 2, and a drying air duct 81 is formed between the outer drum 1 and the inner drum 2. The drying air duct 8 is provided with a fan 8. The drying air flow in the drying air duct 81 is driven by the fan 8 and flows from the drying air duct 81 to the inner drum 2, contacts the clothes to be dried in the inner drum 2, dries the clothes, and then enters the outer drum 1 from the inner drum 2.

[0039] The drying air duct 81 includes a condensing air duct, a fan air duct, and a heating air duct along the flow direction of the drying air flow, and the above-mentioned fan 8 is arranged in the fan air duct.

[0040] The condensation duct includes an outer condensation duct and an inner condensation duct. The inner condensation duct is formed in the inner space of the outer tube, that is, between the inner wall surface of the outer tube bottom and the inner wall surface of the inner tube bottom. The outer condensation duct is formed in the outer space of the outer tube and is formed by the condensation duct housing. Furthermore, the bottom of the inner tube 2 is provided with a first condensation zone that connects the space of the inner tube 2 with the inner space of the outer tube 1, that is, connects the inner tube 2 and the outer tube 1. The bottom of the outer tube 1 is provided with a flow hole that connects the inner space of the outer tube 1 with the outer space of the outer tube 1, that is, connects the inner condensation duct and the outer condensation duct.

[0041] Taking the above application scenario as an example, this application proposes an embodiment of a condensing air duct assembly:

[0042] like Figure 1 As shown, the condensing air duct assembly includes a condensing air duct shell and a spray assembly; wherein

[0043] The condensation air duct housing is arranged on the outer wall surface of the bottom of the outer cylinder to form an outer condensation air duct;

[0044] The spray assembly is provided on the condensing air duct housing and can be controlled to spray water toward the bottom of the inner cylinder through the above-mentioned through-holes and allow the water to flow into the inner cylinder 2 through the through-holes 21. It can also be controlled to spray water into the outer condensing air duct to cool and dehumidify the dry air flow in the outer condensing air duct.

[0045] It should be noted that the space between the inner wall of the outer cylinder 1 and the outer wall of the inner cylinder constitutes the inner space of the outer cylinder, and the area between the inner wall surface of the bottom of the outer cylinder 1 and the outer wall surface of the bottom of the inner cylinder constitutes the above-mentioned first condensation zone. The outer condensation duct formed by the condensation duct shell belongs to the outer space of the outer cylinder, and the second condensation zone 18 is composed of the internal cavity of the condensation duct shell.

[0046] As one embodiment of the spray assembly, the spray assembly can be controlled to spray toward the first condensation zone or the second condensation zone 18, and the fluid sprayed into the first condensation zone can also flow into the inner drum through the through holes at the bottom of the inner drum to achieve clothing care, and the cooling water sprayed into the second condensation zone 18 can achieve cooling and dehumidification of the second condensation zone 18.

[0047] As one embodiment of the spray assembly, the spray assembly 4 is rotatable, and its spray direction can be adjusted by rotating so that it can spray toward the first condensation zone or the second condensation zone 18;

[0048] As two embodiments of the spray assembly, Figure 2-5 As shown, the spray assembly 4 includes a first spray head 9 and a second spray head 10 . The first spray head 9 sprays toward the first condensation zone, and the second spray head 10 sprays toward the second condensation zone 18 .

[0049] The embodiment of the spray assembly provided with the first spray head 9 and the second spray head 10 is advantageous for adapting to the setting of the double condensation zone. Below, we take the embodiment of the spray assembly including the first spray head 9 and the second spray head 10 as an example to further illustrate the structure and spraying method of the condensation air duct assembly:

[0050] Continuing with the above-mentioned clothing processing device as an example, the flow holes at the bottom of the outer drum 1 include a first air outlet and a second air outlet, wherein the first air outlet is positioned lower than the second air outlet. The first air outlet is used to direct at least a portion of the airflow in the inner drum 2 into the bottom of the second condensation zone 18 of the outer condensation duct, and the second air outlet is used to direct the airflow passing through the first condensation zone into the top of the second condensation zone 18 of the outer condensation duct. Therefore, a portion of the dry airflow entering the outer drum 1 is directed to flow upward in the first condensation zone, undergoes condensation in the first condensation zone, and then flows out of the second air outlet to the top of the second condensation zone 18 outside the outer drum 1. This portion of the dry airflow is minimally condensed by the second condensation zone 18. Another portion of the dry airflow entering the outer drum 1 passes through the first air outlet and enters the bottom of the second condensation zone 18 of the outer drum 1, causing this portion to flow upward from the bottom of the second condensation zone 18 and condense in the second condensation zone 18. Finally, the airflow that enters the second condensation zone 18 from the first condensation zone and then enters the drying zone is not subjected to condensation.

[0051] The first spray head 9 is arranged close to the second air outlet and the multiple first spray holes 11 on the first spray head 9 are arranged toward the second air outlet for spraying water mist in the direction of the second air outlet, and the water mist can pass through the second air outlet into the first condensation area and the inner cylinder 2; the second spray head 10 is arranged on the upper part of the condensation duct shell 3 and the multiple second spray holes 12 on the second spray head 10 are arranged inside the condensation duct shell 3 toward the second condensation area 18, spraying water mist onto the second condensation area 18 formed by the condensation duct shell 3, and the water mist contacts the airflow in the second condensation area 18 to condense the drying airflow.

[0052] Preferably, to adapt to the setting that the condensation capacity of the first condensation zone is greater than the condensation capacity of the second condensation zone 18 , the aperture of the first spray hole 11 is smaller than the aperture of the second spray hole 12 .

[0053] It should be noted that the inlet of the fan duct can be arranged at the upper portion of the first condensation zone, so that the drying airflow after condensation in the first condensation zone can directly enter the fan duct, be agitated by the fan 8, and circulate in the drying duct 81. In addition, in one embodiment, the inlet of the fan duct can also be connected to the condensation duct assembly, so that the drying airflow in the condensation duct assembly enters the fan duct and is agitated by the fan 8.

[0054] Based on this, Figure 2-5 As shown, the condensing air duct assembly provided in the embodiment of the present application includes a condensing air duct shell 3 and a spray assembly 4, wherein the condensing air duct shell 3 is used to be connected to the outer side of the bottom of the outer tube 1 away from the inner tube 2; corresponding to the arrangement of the first air outlet and the second air outlet, the condensing air duct shell 3 is provided with a first air vent 5, a second air vent 6 and a return air vent 7. The condensing air duct shell 3 is designed so that after being connected to the outer tube 1, the position of the first air vent 5 is adapted to the position of the first air outlet, and the position of the second air vent 6 is adapted to the position of the second air outlet. The first vent 5 is used to connect the lower part of the condensing air duct shell 3 with the lower part of the first condensation zone, and the second vent 6 is used to connect the upper part of the condensing air duct shell 3 with the upper part of the first condensation zone;

[0055] The return air vent 7 is used to connect to the fan duct of the clothes processing equipment, and introduce the airflow in the condensation duct housing 3 into the fan duct, so that the airflow circulates between the inner drum 2, the outer drum 1, the condensation duct housing 3 and the fan duct;

[0056] The spray assembly 4 is arranged near the second air vent 6, and a through hole 21 is provided on the wall of the inner tube 2 to connect the space of the inner tube 2 and the space of the outer tube 1. The water flow sprayed by the spray assembly 4 can be sprayed toward the inner side of the outer tube 1 and flow into the inner tube 2 through the through hole 21 and sprayed toward the inside of the condensation duct shell 3 to condense the air flow inside the condensation duct shell 3.

[0057] In one embodiment, since the position of the first air vent 5 needs to be adapted to the position of the first air outlet, and the position of the second air vent 6 also needs to be adapted to the position of the second air outlet, the shape and volume of the condensation duct shell 3 need to be designed according to the position of the first air outlet and the second air outlet on the outer tube 1. That is to say, if the distance between the first air outlet and the second air outlet on the outer tube 1 is relatively far, in order to enable the first air vent 5 and the second air vent 6 to meet the corresponding installation conditions at the same time, the length of the condensation duct shell 3 needs to be no less than the distance between the first air outlet and the second air outlet. As for the specific shape and volume of the condensation duct shell 3, this embodiment does not make any specific restrictions.

[0058] In one embodiment, the spray assembly 4 refers to a device capable of spraying water streams, water droplets or water mist, such as a spray head.

[0059] As described above, the condensing duct housing is provided with a first vent and a second vent. The first vent can introduce a portion of the airflow flowing out of the inner drum, allowing the airflow to be condensed within the condensing duct housing, thereby improving the condensation efficiency of the drying airflow of the clothing treatment device and thus improving the drying efficiency of the clothing treatment device. The spray assembly can spray water into the inner drum through the second vent, so that when the clothes are being treated, the water sprayed by the spray assembly enters the inner drum and comes into contact with the clothes, increasing the humidity of the clothes. Due to the certain humidity of the clothes, the treatment effect is higher, thereby improving the treatment effect of the device on the clothes.

[0060] In another embodiment of the present application, the spray assembly 4 includes a first spray head 9 and a second spray head 10, the first spray head 9 is arranged close to the second air vent 6 and the multiple first spray holes 11 on the first spray head 9 are arranged toward the second air vent 6, the second spray head 10 is arranged on the upper part of the condensation duct shell 3 and the multiple second spray holes 12 on the second spray head 10 are arranged toward the inside of the condensation duct shell 3; the first spray head 9 is used to spray water mist in the direction of the second air vent 6, and the water mist passes through the second air vent 6 and the second air outlet into the first condensation area and the inner cylinder 2; the second spray head 10 is used to spray water mist into the condensation duct shell 3, and the water mist contacts the air flow in the condensation duct shell 3 to condense the air flow.

[0061] In one embodiment, the spray assembly 4 includes two spray heads, namely a first spray head 9 and a second spray head 10. Both the first spray head 9 and the second spray head 10 are disposed on the upper portion of the condensation duct housing 3, with the first spray head 9 positioned corresponding to the second vent 6 and the second spray head 10 positioned between the return air vent 7 and the first spray head 9. When the first spray head 9 is turned on, the mist sprayed from the first spray head 9 passes through the second air outlet and the second vent 6 into the first condensation zone. The mist then descends within the first condensation zone, passes through the through-holes 21 of the inner drum 2, and enters the inner drum 2, where it comes into contact with the clothing. When the second spray head 10 is turned on, the mist sprayed from the second spray head 10 falls onto the upper portion of the interior of the condensation duct housing 3. The mist then moves downward from the upper portion of the interior of the condensation duct housing 3, where it comes into contact with the dry airflow in the condensation duct housing 3, condensing the dry airflow and forming a second condensation zone 18 within the condensation duct housing 3.

[0062] Through the above content, by setting the first spray head 9 and the second spray head 10, it is helpful to separately control the condensation situation inside the condensation duct shell 3 and the spraying of water mist into the inner drum 2, so as to better dry and care for clothes.

[0063] In another embodiment of the present application, the aperture of the first spray hole 11 is smaller than the aperture of the second spray hole 12 .

[0064] In one embodiment, the diameter R2 of the first spray hole 11 and the diameter R1 of the second spray hole 12 satisfy the relationship of 2 mm > R1 > R2 > 0 mm.

[0065] As described above, the diameter of the second spray holes 12 is larger than that of the first spray holes 11, which helps improve the condensation efficiency and quality within the condensation duct housing 3, thereby improving the drying quality. At the same time, the water mist sprayed from the smaller-diameter first spray holes 11 is less likely to significantly increase the humidity of the clothes in the inner drum 2, ensuring a certain degree of dryness after the clothes are dried, avoiding secondary drying.

[0066] In another embodiment of the present application, a baffle 13 connected to the condensation duct housing 3 is provided on one side of the second spray head 10 close to the return air outlet 7 , and the baffle 13 is used to prevent water mist from entering the return air outlet 7 .

[0067] In one embodiment, the baffle 13 is arc-shaped, and the bending direction of the baffle 13 is close to the return air inlet 7 , so as to block the water mist sprayed by the second spray head 10 .

[0068] Through the above, by providing baffle 13, it is difficult for the fan duct to contain a large amount of water mist, thereby preventing the fan 8 from being affected by moisture and allowing the drying air flow to reach the specified temperature to ensure drying efficiency. In addition, baffle 13 prevents the amount of water used for condensation within the condensation duct housing 3 from being reduced, thereby ensuring the condensation efficiency and condensation quality within the condensation duct housing 3.

[0069] In another embodiment of the present application, the condensation duct shell 3 includes a bottom plate 14, a side plate 15 and a top plate 16. The bottom plate 14 and the top plate 16 are parallel to each other. The side plate 15 is arranged between the bottom plate 14 and the top plate 16 to form a ring. The side plate 15 is perpendicular to the bottom plate 14. The first air vent 5 and the second air vent 6 are both opened on the bottom plate 14, and the return air vent 7 is opened on the side plate 15.

[0070] In one embodiment, the condensing air duct housing 3 is generally shaped like a pipe, with the side panels 15 connected end to end to form a closed loop, one side of which is connected to the bottom panel 14 and the other side to the top panel 16. It should be noted that the bottom panel 14, the side panels 15, and the top panel 16 can be integrally formed or separately provided.

[0071] Through the above content, the condensation air duct housing 3 has stronger resistance to deformation.

[0072] In another embodiment of the present application, the bottom plate 14 and / or the side plate 15 are provided with through holes, threaded holes and / or clamping blocks for connecting with the bottom of the outer cylinder 1 .

[0073] As described above, the through holes and threaded holes facilitate the use of bolts, screws, and other structures to connect the condensing duct assembly to the outer cylinder 1. The condensing duct assembly can also be installed on the outer cylinder 1 by means of a snap fit. Specifically, the connection structure on the condensing duct assembly can be adapted to the connection structure on the outer cylinder 1 to facilitate the connection between the two, thereby improving the convenience of installing the condensing duct assembly.

[0074] In another embodiment of the present application, a plurality of guide ribs 17 are provided in the condensing air duct housing 3 for guiding the water flow in the condensing air duct housing 3 .

[0075] In one embodiment, a plurality of guide ribs 17 are bent and have different bending directions, so as to guide the water flow in the condensation duct shell 3 to spread over the condensation duct shell 3, increase the contact area with the drying air flow, and improve the condensation efficiency.

[0076] Example 2

[0077] like Figure 1 As shown, the clothes processing device of this embodiment includes the condensing air duct assembly of the above embodiment, and the clothes processing device is a clothes dryer or a washer-dryer;

[0078] The laundry processing apparatus includes an outer drum 1 and an inner drum 2. A drying duct 81 is formed between the outer drum 1 and the inner drum 2. A fan 8 is provided in the drying duct 8. The dry airflow in the drying duct 81 is driven by the fan 8 and flows from the drying duct 81 to the inner drum 2. There, the dry airflow comes into contact with the laundry to be dried, drying the laundry before entering the outer drum 1 from the inner drum 2. The drying duct 81 includes a condensing duct, a fan duct, and a heating duct along the dry airflow direction. The fan 8 is provided in the fan duct.

[0079] The condensation air duct includes an outer condensation air duct and an inner condensation air duct. The inner condensation air duct is formed in the inner space of the outer tube, that is, between the inner wall surface of the outer tube bottom and the inner wall surface of the inner tube bottom, forming a second condensation area 18. The outer condensation air duct is formed in the outer space of the outer tube, forming a second condensation area 18. Furthermore, the bottom of the inner tube 2 is provided with a through hole connecting the space of the inner tube 2 with the inner space of the outer tube 1, that is, connecting the first condensation areas of the inner tube 2 and the outer tube 1. The bottom of the outer tube 1 is provided with a through hole connecting the inner space of the outer tube 1 with the outer space of the outer tube 1, that is, connecting the inner condensation air duct and the outer condensation air duct.

[0080] The flow holes at the bottom of the outer tube 1 include a first air outlet and a second air outlet opened on the bottom of the outer tube 1, wherein the position of the first air outlet is lower than that of the second air outlet. The first air outlet is used to introduce at least part of the airflow in the inner tube 2 into the bottom of the second condensation zone 18 of the outer condensation duct, and the second air outlet is used to introduce the airflow passing through the first condensation zone into the top of the second condensation zone 18 of the outer condensation duct.

[0081] The spray assembly is arranged on the condensing air duct housing and can be controlled to spray water through the through-hole to the second condensing area 18 located at the bottom of the inner tube and allow the water to flow into the inner tube (2) through the through-hole (21). It can also be controlled to spray water to the second condensing area 18 located in the outer condensing air duct to cool and dehumidify the drying air flow in the outer condensing air duct.

[0082] Finally, the airflow from the first condensation zone and the second condensation zone 18 is sucked into the heating air duct by the fan duct for further heating, and then returns to the inner drum for further drying and heating, thereby completing a drying airflow cycle.

[0084] The present application also provides a drying method, which is applied to a clothes processing device including the above-mentioned condensing air duct assembly, and the method includes:

[0085] In response to the drying signal, the fan 8 in the fan duct is controlled to start, so as to drive the drying air flow to circulate in the fan duct, the inner drum 2, the outer drum 1 and the condensing duct housing 3;

[0086] Monitor the drying process and control the spray assembly 4 to spray condensed water into the condensing air duct housing 3 and / or spray cooling water into the inner drum 2 according to the drying process requirements:
