The thermal resistance of the rear wall 12 and the condensing air duct 133, the outer cylinder 1 after being heated by the drying airflow can keep the drying airflow circulating in the condensing air duct 133 warm and heat it, thereby reducing heat loss and achieving faster drying; the condensing shell 131 and the condensing cover 132 are fixed by welding, screws or fixing clips; the condensing shell 131 and the condensing cover 132 are sealed and connected to prevent water leakage in the condensing air duct 133; an outer guide rib 151 is provided in the condensing air duct 133, and the outer guide rib 151 can be a linear structure or an arc structure; a plurality of outer guide ribs 151 are provided, and the plurality of outer guide ribs 151 are sequentially spaced and staggered along the length direction of the condensing air duct 133; the position and / or extension direction and / or extension length of the outer guide rib 151 can be adjusted;

[0047] The heating air duct 32 is connected to the drying air inlet at one end, and is connected to the condensing air outlet 134 at the other end via the drying fan 31. The inner side surface of the outer cylinder rear wall 12 serves as a condensing surface, through which condensed water can flow. A portion of the drying air flow in the outer cylinder 1 completes heat exchange with the condensed water flowing through the condensing surface when flowing along the inner side surface of the outer cylinder rear wall 12, and then enters the condensing air duct 133 through the first drying air outlet 121. A heating device is provided in the heating air duct 32 to heat the drying air flow flowing through the heating air duct 32. Specifically, the heating device is an electric heater. The drying air flow in the heating air duct 32 enters the tube mouth of the inner cylinder through the drying air inlet.

The drying time is shortened; the drying air in the condensing air duct 133 can enter the heating air duct through the condensing air outlet 134; the outer cylinder 1, the inner cylinder, the condensing air duct 133, the drying fan 31 and the heating air duct 32 form a drying air flow loop, and the drying fan 31 provides power to the drying air flow, so that the drying air flow circulates in the drying air flow loop; specifically, the condensing pipe 21 is arranged on the inner side surface of the condensing cover 132 through the fixing clamp 22; the position, extension length and formed structure of the condensing pipe can be adjusted according to actual needs, thereby expanding the application range of the condensing pipe;

[0049] A condenser 21 is provided at the location where the drying airflow velocity is maximum in the condensation duct 133, and condensed water is sprayed out of the condenser 21 to form a water curtain; the heat exchange area between the drying airflow and the condensed water is increased, so that the drying airflow and the condensed water are in full contact; the water curtain is used to further absorb hair debris and impurities in the drying airflow.

[0050] A condensate inner water inlet valve 141 is provided at one end of the outer tube peripheral wall 11 close to the outer tube rear wall 12. The condensate inner water inlet valve 141 is connected to the outer tube 1. Condensate from the outside can enter the outer tube 1 through the condensate inner water inlet valve 141, flow from top to bottom along the inner side surface of the outer tube rear wall 12, and exchange heat with the drying air flow flowing through the inner side surface of the outer tube rear wall 12.

[0051] A condensation external water inlet valve 142 is provided on the side wall of the condensation shell 131. The condensation external water inlet valve 142 is connected to the condensation pipe 21. The external condensation water can enter the condensation pipe 21 through the condensation external water inlet valve 142 and be sprayed out through multiple spray holes. Then, it enters the condensation air duct 133 and flows from top to bottom and exchanges heat with the drying air flow in the condensation air duct 133. The external guide ribs 151 play a guiding role and can slow down the flow rate of the condensation water, increase the heat exchange area between the condensation water and the drying air flow, improve the condensation efficiency, and save condensation water.

[0052] The first drying air outlet 121 and the second drying air outlet 122 can be independently controlled to be opened or closed; according to actual drying needs, the first drying air outlet 121 can be opened and the second drying air outlet 122 can be closed, and the drying air flow in the outer drum 1 enters the condensing air duct 133 through the inner side surface of the outer drum rear wall 12 and the first drying air outlet 121; or the second drying air outlet 122 can be opened and the first drying air outlet 121 can be closed, and the drying air flow in the outer drum 1 enters the condensing air duct 133 through the second drying air outlet 122; or both the first drying air outlet 121 and the second drying air outlet 122 can be opened, a part of the drying air flow in the outer drum 1 enters the condensing air duct 133 through the inner side surface of the outer drum rear wall 12 and the first drying air outlet 121, and another part of the drying air flow in the outer drum 1 enters the condensing air duct 133 through the second drying air outlet 122.

[0053] To address the problem of low condensation efficiency caused by the unreasonable structural design of the condenser 21, this embodiment proposes that the condensation air duct 133 includes a first condensation section 1331 and a second condensation section 1332. One end of the first condensation section 1331 is connected to the first drying air outlet 121, one end of the second condensation section 1332 is connected to the second drying air outlet 122, and the other end of the first condensation section 1331 is connected to the other end of the second condensation section 1332. The first condensation section 1331 and the second condensation section 1332 are both arc-shaped structures, and the flow area of ​​the first condensation section 1331 is smaller than the flow area of ​​the second condensation section 1332.

[0054] The condenser pipe 21 is disposed at the connection point between the first condenser section 1331 and the second condenser section 1332, and includes a first pipe section 211 and a second pipe section 212. The first pipe section 211 is adjacent to the first condenser section 1331, and the second pipe section 212 is adjacent to the second condenser section 1332. The second pipe section 212 is connected to the first pipe section 211 and surrounds the first pipe section 211 to form a three-dimensional annular structure.

[0055] The drying airflow in the first condensation section 1331 can flow through the first pipe section 211 and heat exchange with the condensed water ejected from the first pipe section 211 , and the drying airflow in the second condensation section 1332 can flow through the second pipe section 212 and heat exchange with the condensed water ejected from the second pipe section 212 .

[0056] Furthermore, the structure formed by the first pipe section 211 is adapted to the inner contour of the first condensing section 1331. The side wall of the first pipe section 211 is formed with a plurality of first spray holes 213. The condensed water sprayed from the plurality of first spray holes 213 can exchange heat with the drying air flow flowing through the first condensing section 1331.

[0057] The structure formed by the second pipe section 212 is adapted to the inner contour of the second condensation section 1332 , and a plurality of second spray holes 214 are formed on the side wall of the second pipe section 212 . The condensed water sprayed from the plurality of second spray holes 214 can be heat exchanged with the drying air flow flowing through the second condensation section 1332 .

[0058] To address the problem of poor condensation effect caused by unreasonable structural design and unreasonable position setting of the first spray hole 213 and the second spray hole 214, this embodiment proposes that the first spray hole 213 is a circular hole and the second spray hole 214 is a waist-shaped hole;

[0059] The first spray holes 213 are oriented toward the center line of the structure surrounded by the first condensing section 1331. The condensed water sprayed from the multiple first spray holes 213 can cover the cross section of the structure surrounded by the first condensing section 1331, so that the condensed water is fully in contact with the drying airflow in the first condensing section 1331, thereby improving the heat exchange efficiency.

[0060] The second spray hole 214 faces one end of the second drying air outlet 122, and the condensed water sprayed from multiple second spray holes 214 flows from top to bottom and can exchange heat with the drying air flow flowing from bottom to top, so that the condensed water is fully in contact with the drying air flow in the second condensation section 1332, thereby improving the heat exchange efficiency.

[0061] Furthermore, a first plane formed by the first tube segment 211 is perpendicular to a second plane formed by the second tube segment 212 .

[0062] In order to address the problem of low drying efficiency caused by unreasonable structural design of the first drying air outlet 121 and the second drying air outlet 122, this embodiment proposes that the diameter of the first drying air outlet 121 is d1, and the diameter of the second drying air outlet 122 is d2, satisfying: 18mm≤d1≤35mm, 35mm≤d2≤50mm; in this way, most of the drying air flow enters the condensation air duct 133 through the second drying air outlet 122, and a small part of the drying air flow enters the condensation air duct 133 through the first drying air outlet 121, thereby increasing the heat exchange area between the drying air flow and the condensed water and improving the condensation effect.

[0063] The extension length of the outer guide ribs 151 is L, 20 mm ≤ L ≤ 100 mm; the condensed water entering the condensation air duct 133 can flow along the outer guide ribs 151, extending the flow path of the condensed water and expanding the heat exchange area between the condensed water and the drying airflow; the outer guide ribs 151 are arranged at intervals and staggered, and when the drying airflow flows through the condensation air duct 133, the outer guide ribs 151 can block debris, which can fall with the condensed water flowing along the outer guide ribs 151 and eventually be discharged from the outer drum 1. This can prevent debris from entering the drying fan, ensuring the reliable operation of the drying fan.

[0064] The outer guide rib 151 is formed with a plurality of through holes, which are arranged in sequence and spaced apart along the length of the outer guide rib 151. When the drying airflow flows through the through holes, the hair debris therein can be intercepted by the through holes, thereby achieving the effect of removing the hair debris.

[0065] In response to the problem of poor diversion effect caused by unreasonable positioning of external guide ribs, this embodiment proposes that the external guide ribs 151 include multiple first external guide ribs, and the multiple first external guide ribs are all arranged on the condensation cover 132 and the multiple first external guide ribs are arranged in sequence along the length direction of the condensation cover 132, and the extension direction of each first external guide rib is inclined relative to the vertical direction; after the condensed water enters the condensation air duct 133, it flows along the inner side surface of the condensation cover 132 and flows through the multiple first external guide ribs; on the one hand, the condensed water can exchange heat with the condensation cover 132; on the other hand, the condensed water can exchange heat with the drying airflow, and both types of heat exchanges are beneficial to reducing the humidity of the drying airflow.

[0066] Furthermore, the position and / or extension direction and / or extension length of the first outer guide rib can be adjusted on the condensation cover 132; the position, extension direction and extension length of the first outer guide rib can be adjusted according to actual needs, thereby adjusting the flow rate and flow state of the condensed water and improving the heat exchange efficiency between the condensed water and the drying airflow;

[0067] Among the two adjacent first outer guide ribs, the water outlet end of the upstream first outer guide rib is close to the water inlet end of the downstream first outer guide rib, so that the condensed water entering the condensation air duct 133 can flow through multiple first outer guide ribs in sequence; the flow path of the condensed water in the condensation air duct 133 is extended, the heat exchange area between the condensed water and the drying air flow is increased, and the condensation efficiency is improved.

[0068] In response to the problem of poor diversion effect caused by unreasonable positioning of the external guide ribs, this embodiment also proposes that the external guide ribs 151 also include multiple second external guide ribs, and the multiple second external guide ribs are all arranged on the outer side of the outer cylinder rear wall 12 and the multiple second external guide ribs are arranged in sequence along the length direction of the condensation shell 131, and the extension direction of each second external guide rib is inclined relative to the vertical direction; after the condensed water enters the condensation air duct 133, it flows along the outer side surface of the outer cylinder rear wall 12 and flows through the multiple second external guide ribs; on the one hand, the condensed water can exchange heat with the outer cylinder rear wall 12; on the other hand, the condensed water can exchange heat with the drying air flow, and both types of heat exchanges are beneficial to reducing the humidity of the drying air flow.

[0069] Furthermore, the position and / or extension direction and / or extension length of the second outer guide rib can be adjusted on the outer side of the outer cylinder rear wall 12; the position, extension direction and extension length of the second outer guide rib can be adjusted according to actual needs, thereby adjusting the flow rate and flow state of the condensed water and improving the heat exchange efficiency between the condensed water and the drying airflow;

[0070] Among the two adjacent second outer guide ribs, the water outlet end of the upstream second outer guide rib is close to the water inlet end of the downstream second outer guide rib, so that the condensed water entering the condensation air duct 133 can flow through multiple second outer guide ribs in sequence; the flow path of the condensed water in the condensation air duct 133 is extended, the heat exchange area between the condensed water and the drying air flow is increased, and the condensation efficiency is improved.

[0071] A plurality of first drying air outlets 121 are sequentially arranged along the extension direction of the first condensation section 1331, and each first drying air outlet 121 can be independently controlled to be opened or closed; a plurality of second drying air outlets 122 are sequentially arranged along the extension direction of the second condensation section 1332, and each second drying air outlet 122 can be independently controlled to be opened or closed; according to actual drying needs, the first drying air outlets 121 and the second drying air outlets 122 at corresponding numbers and positions can be opened, so that the drying air flow in the outer tube 1 enters the condensation air duct 133 through the first drying air outlet 121 and the second drying air outlet 122 respectively, thereby extending the flow path of the drying air flow, increasing the heat exchange area between the drying air flow and the condensed water, and improving the condensation efficiency.

[0072] In addition, a plurality of inner guide ribs 152 are provided at intervals on the inner side surface of the outer cylinder rear wall 12. The extension direction of each inner guide rib 152 is inclined relative to the vertical direction. In addition, the outlet end of the upstream inner guide rib 152 of two adjacent inner guide ribs 152 is close to the inlet end of the downstream inner guide rib 152, so that the condensed water flowing along the inner side surface of the outer cylinder rear wall 12 can flow through the plurality of inner guide ribs 152. The position, extension direction, and / or extension length of the inner guide ribs 152 are adjustable.

[0073] When the condensed water flows through the inner guide ribs 152 , the heat exchange time and heat exchange area between the condensed water and the drying air flow can be extended, thereby improving the condensation effect.

[0074] The clothing processing equipment runs a drying process. When the temperature of the drying airflow in the inner drum reaches the drying temperature, the condensation inner water inlet valve 141 is opened, allowing a part of the condensed water to enter the outer drum 1 through the condensation inner water inlet valve 141 and flow along the inner side surface of the outer drum rear wall 12. This part of the condensed water exchanges heat with the drying airflow flowing along the inner side surface of the outer drum rear wall 12, and this part of the drying airflow enters the condensation duct 133 through the first drying air inlet 121; the condensation outer water inlet valve 142 is opened, allowing another part of the condensed water to enter the condensation pipe 21 through the condensation outer water inlet valve 142, and then enter the condensation duct 133 through the spray hole and form a water curtain. The water curtain is in full contact with the drying airflow in the condensation duct 133 and exchanges heat, thereby improving the condensation efficiency and shortening the drying time; at the same time, the water curtain can absorb hair debris and impurities in the drying airflow.

[0075] Example 2

[0076] On the basis of the difference from Example 1, each inner guide rib 152 is formed with a guide groove and a dripping hole, and the extension direction of the guide groove is consistent with the extension direction of the inner guide rib; the dripping hole is close to the inner side surface of the rear wall 12 of the outer cylinder, and a plurality of dripping holes are provided; the plurality of dripping holes are sequentially spaced along the extension direction of the guide groove, and each dripping hole is connected to the guide groove;

[0077] In two adjacent inner guide ribs 152, the condensed water in the upstream guide groove can be discharged through the corresponding drip holes and flow along the transition surface to the downstream guide groove;

[0078] The transition surface is the portion of the inner surface of the outer cylinder rear wall 12 between two adjacent inner guide ribs 152;

[0079] In this embodiment, the condensed water in the guide groove is discharged through each drip hole and flows along the transition surface. On the one hand, it can reduce the flow rate of the condensed water, and on the other hand, it expands the flow area of ​​the condensed water, so that the condensed water and the drying airflow are fully in contact, and the condensed water is fully utilized for dehumidification, solving the problem of poor condensation effect caused by excessive condensed water flow rate and small contact area between condensed water and drying airflow.

[0080] While the exemplary embodiments of the present disclosure have been specifically illustrated and described above, it should be understood that the present disclosure is not limited to the detailed structures, configurations, or implementations described herein; rather, the present disclosure is intended to encompass various modifications and equivalent configurations within the spirit and scope of the appended claims.
