[0047] Example 1

[0048] <Outer Cylinder Assembly>

[0049] like Figures 1 to 3 As shown, this embodiment provides an outer drum assembly for a clothes processing device; the clothes processing device includes an inner drum, the inner drum includes an inner drum rear wall and the inner drum is rotatably arranged for carrying clothes; the outer drum assembly includes an outer drum 1 and a condensation cover 132, the outer drum 1 is arranged around the outside of the inner drum; the outer drum 1 includes an outer drum rear wall 12 and an outer drum peripheral wall 11, and the outer drum rear wall 12 and the inner drum rear wall are arranged correspondingly, and the outer drum peripheral wall 11 is arranged around one axial side of the outer drum rear wall 12; the inner side surface of the outer drum rear wall 12 is formed with a first condensation surface, and a first condensation area is formed between the first condensation surface and the outer side surface of the inner drum rear wall;

[0050] A second condensation surface is formed on the outer side of the outer cylinder rear wall 12, and a condensation shell 131 is integrally injection-molded on the second condensation surface; an opening is formed on the side of the condensation shell 131 away from the outer cylinder rear wall 12; a condensation cover 132 is provided on the opening, and a third condensation surface is formed on the inner side of the condensation cover 132; a second condensation area 133 is formed between the second condensation surface and the third condensation surface;

[0051] The outer tube rear wall 12 is formed with a first outer tube air outlet 121 and a second outer tube air outlet 122. The first outer tube air outlet 121 is located above the second outer tube air outlet 122. The first outer tube air outlet 121 communicates with the upper ends of the first condensation area and the second condensation area 133, while the second outer tube air outlet 122 communicates with the lower ends of the first condensation area and the second condensation area 133.

[0052] The first condensation surface, the second condensation surface and the third condensation surface can all flow through the condensed water from top to bottom and through the drying air flow from bottom to top;

[0053] Specifically, the condensation shell 131 and the rear wall 12 of the outer cylinder are integrally injection-molded to reduce the thermal resistance of the first condensation zone and the second condensation zone 133 during drying. The outer cylinder 1 heated by the drying airflow can heat and increase the temperature of the drying airflow circulating in the first condensation zone and the second condensation zone 133, thereby reducing heat loss and achieving faster drying. The condensation shell 131 and the condensation cover 132 are fixed by welding, screws or buckles. The condensation shell 131 and the condensation cover 132 are sealed to prevent water leakage in the second condensation zone 133.

[0054] The first portion of condensed water can enter the first condensation zone and flow from top to bottom along the first condensation surface. The first portion of dry airflow in the outer tube 1 can enter the first condensation zone and flow from bottom to top along the first condensation surface. In this way, the first portion of dry airflow can exchange heat with the first portion of condensed water. After heat exchange, the first portion of dry airflow enters the second condensation zone 133 through the first outer tube outlet 121.

[0055] The second part of the condensed water can enter the second condensation area 133 and flow from top to bottom along the second condensation surface and the third condensation surface. The second part of the drying airflow in the outer tube 1 can enter the first condensation area through the second outer tube air outlet 122 and flow from bottom to top along the second condensation surface and the third condensation surface. In this way, the second part of the drying airflow can exchange heat with the second part of the condensed water.

[0056] To address the problem that condensed water cannot smoothly enter the first condensation zone and the second condensation zone 133, this embodiment proposes that a condensation inner water inlet valve 141 is provided at one end of the outer cylinder peripheral wall 11 close to the outer cylinder rear wall 12. The condensation inner water inlet valve 141 is connected to the first condensation zone, and external condensed water can enter the first condensation zone through the condensation inner water inlet valve 141; a condensation outer water inlet valve 142 is provided on the side wall of the condensation shell 131, and external condensed water can enter the second condensation zone 133 through the condensation outer water inlet valve 142;

[0057] The first part of the condensed water can enter the first condensation zone through the inner condensation water inlet valve 141 and flow along the first condensation surface from top to bottom and exchange heat with the drying air flow flowing through the first condensation surface; the second part of the condensed water can enter the second condensation zone 133 through the outer condensation water inlet valve 142 and flow along the second condensation surface and the third condensation surface, and at the same time exchange heat with the drying air flow flowing through the second condensation surface and the third condensation surface.

[0058] The first outer tube air outlet 121 and the second outer tube air outlet 122 can both be independently controlled to be opened or closed; according to actual drying needs, the first outer tube air outlet 121 can be opened and the second outer tube air outlet 122 can be closed, and the drying air flow in the outer tube 1 enters the second condensation area 133 through the first condensation surface and the first outer tube air outlet 121; or the second outer tube air outlet 122 can be opened and the first outer tube air outlet 121 can be closed, and the drying air flow in the outer tube 1 enters the second condensation area 133 through the second outer tube air outlet 122; or both the first outer tube air outlet 121 and the second outer tube air outlet 122 can be opened, and the first part of the drying air flow in the outer tube 1 enters the second condensation area 133 through the first condensation surface and the first outer tube air outlet 121, and the second part of the drying air flow in the outer tube 1 enters the second condensation area 133 through the second outer tube air outlet 122.

[0059] In order to address the problem of low drying efficiency caused by unreasonable structural design of the first outer cylinder air outlet 121 and the second outer cylinder air outlet 122, this embodiment proposes that the diameter of the first outer cylinder air outlet 121 is d1, and the diameter of the second outer cylinder air outlet 122 is d2, satisfying: 5mm≤d1≤50mm, 8mm≤d2≤80mm; in this way, most of the drying air flow enters the second condensation area 133 through the second outer cylinder air outlet 122, and a small part of the drying air flow enters the second condensation area 133 through the first condensation surface and the first outer cylinder air outlet 121, thereby increasing the heat exchange area between the drying air flow and the condensed water and improving the condensation effect.

[0060] To address the problem of low drying efficiency caused by unreasonable positioning of the first outer drum air outlet 121 and the second outer drum air outlet 122, this embodiment proposes that the angle α between the plane where the axis of the first outer drum air outlet 121 is located and the vertical reference plane satisfies the following conditions: -60°≤α≤60°; the angle β between the plane where the axis of the second outer drum air outlet 122 is located and the vertical reference plane satisfies the following conditions: -80°≤β≤80°;

[0061] Among them, the plane where the axis of the first outer tube air outlet 121 is located is the plane passing through the axis of the first outer tube air outlet 121 and the axis of the outer tube 1; the plane where the axis of the second outer tube air outlet 122 is located is the plane passing through the axis of the second outer tube air outlet 122 and the axis of the outer tube 1; the vertical reference plane is the plane passing through the axis of the outer tube 1 and parallel to the vertical plane.

[0062] External guide ribs are provided in the second condensation area 133. When the condensed water flows through the second condensation surface and the third condensation surface, the condensed water can flow through the external guide ribs. The external guide ribs can be a linear structure or an arc structure. The external guide ribs can not only guide the water but also slow down the flow rate of the condensed water, thereby increasing the heat exchange area between the condensed water and the drying air flow, thereby improving the condensation efficiency and saving condensed water.

[0063] There are multiple external guide ribs, which are arranged in sequence at intervals relative to the horizontal plane, and two adjacent external guide ribs are staggered in the horizontal direction; the extension direction of each external guide rib is inclined relative to the vertical direction, and two adjacent external guide ribs have different extension directions; the position and / or extension direction and / or extension length of the external guide ribs can be adjusted.

[0064] 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 include multiple first external guide ribs 151, and the multiple first external guide ribs 151 are all arranged or formed on the third condensation surface. The multiple first external guide ribs 151 are arranged in sequence along the extension direction of the condensation cover 132; the extension direction of each first external guide rib 151 is inclined relative to the vertical direction, and two adjacent first external guide ribs 151 have different extension directions; after entering the second condensation area 133, the condensed water flows along the third condensation surface and flows through the multiple first external guide ribs 151; 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 conducive to reducing the humidity of the drying airflow.

[0065] Furthermore, the position and / or extension direction and / or extension length of the first outer guide rib 151 can be adjusted on the third condensation surface; the position, extension direction and extension length of the first outer guide rib 151 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; specifically, the first outer guide rib 151 can be detachably provided on the third condensation surface, thereby adjusting the position of the first outer guide rib 151 on the third condensation surface; or the first outer guide rib 151 can be rotatably provided on the third condensation surface, thereby adjusting the extension direction of the first outer guide rib 151; or the first outer guide rib 151 is made of a flexible material, thereby adjusting the extension length of the first outer guide rib 151;

[0066] Among the two adjacent first outer guide ribs 151, the water outlet end of the upstream first outer guide rib 151 is close to the water inlet end of the downstream first outer guide rib 151, so that the condensed water flowing along the third condensation surface can flow through multiple first outer guide ribs 151 in sequence; the flow path of the condensed water in the second condensation area 133 is extended, the heat exchange area between the condensed water and the drying air flow is increased, and the condensation efficiency is improved.

[0067] To address the problem of poor diversion effect caused by unreasonable structural design of the first outer guide rib 151, this embodiment proposes that the thickness of the first outer guide rib 151 is h1, the width of the first outer guide rib 151 is b1, and the length of the first outer guide rib 151 is a1, satisfying the following conditions: 1.5mm≤h1≤8mm, 1.5mm≤b1≤6mm, 5mm≤a1≤80mm; so that the first outer guide rib 151 can effectively divert condensed water without affecting the flow of drying air.

[0068] In response to the problem of poor diversion effect caused by unreasonable positioning of the outer guide ribs, this embodiment further proposes that the outer guide ribs also include a plurality of second outer guide ribs 152, and the plurality of second outer guide ribs 152 are all arranged or formed on the second condensation surface. The plurality of second outer guide ribs 152 are arranged in sequence along the extension direction of the condensation cover 132; the extension direction of each second outer guide rib 152 is inclined relative to the vertical direction, and two adjacent second outer guide ribs 152 have different extension directions; after entering the second condensation area 133, the condensed water flows along the second condensation surface and flows through the plurality of second outer guide ribs 152; on the one hand, the condensed water can exchange heat with the rear wall 12 of the outer cylinder; on the other hand, the condensed water can exchange heat with the drying airflow, and both types of heat exchanges are conducive to reducing the humidity of the drying airflow.

[0069] Furthermore, the position and / or extension direction and / or extension length of the second outer guide rib 152 can be adjusted on the second condensation surface; the position, extension direction and extension length of the second outer guide rib 152 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; specifically, the second outer guide rib 152 can be detachably provided on the second condensation surface, thereby adjusting the position of the second outer guide rib 152 on the second condensation surface; or the second outer guide rib 152 can be rotatably provided on the second condensation surface, thereby adjusting the extension direction of the second outer guide rib 152; or the second outer guide rib 152 is made of a flexible material, thereby adjusting the extension length of the second outer guide rib 152;

[0070] Among the two adjacent second outer guide ribs 152, the water outlet end of the upstream second outer guide rib 152 is close to the water inlet end of the downstream second outer guide rib 152, so that the condensed water flowing along the second condensation surface can flow through multiple second outer guide ribs 152 in sequence; the flow path of the condensed water in the second condensation area 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] To address the problem of poor guiding effect caused by unreasonable structural design of the second outer guide rib 152, this embodiment proposes that the thickness of the second outer guide rib 152 is h2, the width of the second outer guide rib 152 is b2, and the length of the second outer guide rib 152 is a2, satisfying the following conditions: 1.5 mm ≤ h2 ≤ 12 mm, 1.5 mm ≤ b2 ≤ 10 mm, and 5 mm ≤ a2 ≤ 100 mm.

[0072] In order to solve the problem that the condensation effect is poor due to the unreasonable structural design of the second condensation area 133, this embodiment proposes that the second condensation area 133 includes an A condensation section 1331, a B condensation section 1332 and an air outlet section 1333, one end of the A condensation section 1331 is connected to the first outer tube air outlet 121, one end of the B condensation section 1332 is connected to the second outer tube air outlet 122, and the other end of the A condensation section 1331 and the other end of the B condensation section 1332 are connected to the second outer tube air outlet 122. Condensation section A 1331 and condensation section B 1332 are both arc-shaped structures, and the flow area of ​​condensation section A 1331 is smaller than the flow area of ​​condensation section B 1332; the air outlet section 1333 is provided at the connection point between condensation section A 1331 and condensation section B 1332, and one end of the air outlet section 1333 is connected to both condensation section A 1331 and condensation section B 1332; the other end of the air outlet section 1333 is formed with a condensation air outlet 134;

[0073] A plurality of first outer cylinder air outlets 121 are sequentially arranged along the extension direction of the A condensation section 1331, and each first outer cylinder air outlet 121 can be independently controlled to be opened or closed; a plurality of second outer cylinder air outlets 122 are sequentially arranged along the extension direction of the B condensation section 1332, and each second outer cylinder air outlet 122 can be independently controlled to be opened or closed; according to actual drying needs, the first outer cylinder air outlets 121 and the second outer cylinder air outlets 122 at corresponding numbers and positions can be opened, so that the drying air flow in the outer cylinder 1 enters the second condensation area 133 through the first outer cylinder air outlet 121 and the second outer cylinder 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.

[0074] In addition, the first condensing surface is provided with a plurality of inner guide ribs, which are arranged at intervals on the first condensing surface, and the extension direction of each inner guide rib is inclined relative to the vertical direction; the position and / or extension direction and / or extension length of the inner guide ribs are adjustable;

[0075] When the condensed water flows through the inner guide ribs, 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.

[0078] The drying air inlet, the first outer cylinder air outlet 121 and the second outer cylinder air outlet 122 are all provided with filters to filter hair debris in the drying air flow; the drying air inlet, the first outer cylinder air outlet 121 and the second outer cylinder air outlet 122 are all provided with flushing valves, which can spray water to the corresponding filters to clean the corresponding filters; specifically, a door seal is provided at the tube mouth of the outer cylinder 1, and the door seal forms a drying air inlet, and the drying air flow in the heating air duct enters the tube mouth of the inner cylinder through the drying air inlet; the first outer cylinder air outlet 121 is located on the upper side of the horizontal reference plane, and the second outer cylinder air outlet 122 is located on the lower side of the horizontal reference plane, where the horizontal reference plane is a plane passing through the axis of the outer cylinder and parallel to the horizontal plane; the flow area of ​​the first outer cylinder air outlet 121 is smaller than the flow area of ​​the second outer cylinder air outlet 122;

[0079] The drying airflow in the second condensation zone 133 can enter the heating air duct through the condensation air outlet 134; a heating device is provided in the heating air duct to heat the drying airflow flowing through the heating air duct; the outer cylinder 1, the inner cylinder, the first condensation zone, the second condensation zone 133, the drying fan and the heating air duct constitute a drying airflow loop, and the drying fan provides power to the drying airflow so that the drying airflow circulates in the drying airflow loop; specifically, the heating device is an electric heating element.

[0080] <Drying control method>

[0081] like Figure 4 As shown, this embodiment provides a drying control method for a clothes processing device, wherein the clothes processing device is any of the clothes processing devices described above, and the clothes processing device is provided with a drying process, which includes a drying stage and a drying and cooling stage; when the clothes processing device is in the drying stage, the drying control method includes:

[0082] S1. Obtain the current temperature of the drying airflow in the outer drum 1;

[0083] S2, determine whether the current temperature is within the preset temperature range;

[0084] S3, controlling the condensed water to enter the first condensation zone and / or the second condensation zone 133 according to the judgment result of whether the current temperature is within the preset temperature range;

[0085] Specifically, when the clothes processing device runs the drying process, the heating device and the drying fan are both turned on; the preset temperature range is 55°C-65°C.

[0086] Furthermore, S3 includes:

[0087] When the current temperature is within the preset temperature range, the condensate inlet valve 141 is opened, allowing the first portion of condensate to enter the first condensation zone through the condensate inlet valve 141 and flow along the first condensation surface, and the time is counted. At this time, the condensate flowing through the first condensation surface can initially dehumidify the drying airflow in the first condensation zone.

[0088] Compare the measured duration with the preset duration;

[0089] When the timed duration is longer than the preset time, the condensation external water inlet valve 142 is opened, allowing the second portion of condensed water to enter the second condensation area 133 through the condensation external water inlet valve 142 and flow along the second condensation surface and the third condensation surface; at this time, the first condensation surface, the second condensation surface and the third condensation surface can all flow through the condensed water, and the condensed water can fully contact with the drying airflow, so that the drying airflow is quickly cooled and a large amount of condensed water is precipitated. This ensures that the water on the clothes in the inner drum evaporates sufficiently and that the water in the drying airflow condenses sufficiently, so that the clothes in the inner drum dry quickly; the preset time is 10 minutes;

[0090] When the clothing processing device is in the drying and cooling stage, the condensation inner water inlet valve 141 and the condensation outer water inlet valve 142 are opened to reduce the temperature in the inner drum to prevent excessive temperature from damaging the clothing.

[0091] Example 2

[0092] Different from Example 1, each first outer guide rib 151 is formed with a first guide groove and a first dripping hole. The extension direction of the first guide groove is consistent with the extension direction of the first outer guide rib 151. The first dripping hole is close to the third condensation surface and multiple first dripping holes are provided. The multiple first dripping holes are arranged in sequence along the extension direction of the first guide groove, and each first dripping hole is connected to the first guide groove.

[0093] In two adjacent first outer guide ribs 151, condensed water in the upstream first guide groove can be discharged through the corresponding first dripping hole and flow along the first transition surface to the downstream first guide groove;

[0094] The first transition surface is the portion of the third condensation surface between two adjacent first outer guide ribs 151 .

[0095] Each second outer guide rib 152 is formed with a second guide groove and a second dripping hole. The extension direction of the second guide groove is consistent with the extension direction of the second outer guide rib 152. The second dripping hole is close to the second condensation surface and a plurality of second dripping holes are provided. The plurality of second dripping holes are arranged in sequence along the extension direction of the second guide groove, and each second dripping hole is connected to the second guide groove.

[0096] In two adjacent second outer guide ribs 152 , condensed water in the upstream second guide groove can be discharged through the corresponding second dripping holes and flow along the second transition surface to the downstream second guide groove;

[0097] The second transition surface is the portion of the second condensation surface between two adjacent second outer guide ribs 152 .

[0098] In this embodiment, the condensed water in the first guide groove is discharged through each first drip hole and flows along the first transition surface, and the condensed water in the second guide groove is discharged through each second drip hole and flows along the second transition surface. On the one hand, the flow rate of the condensed water can be reduced, and on the other hand, the flow area of ​​the condensed water is expanded, so that the condensed water and the drying airflow are fully in contact, and the condensed water is fully utilized for dehumidification, which solves the problem of poor condensation effect caused by excessive condensed water flow rate and small contact area between condensed water and drying airflow.

[0100] Different from Example 1, the condensation shell 131 includes a condensation outer shell and a condensation inner shell. The condensation outer shell is sleeved on the outer side of the condensation inner shell. The condensation inner shell, the outer side surface of the outer cylinder rear wall 12 and the condensation cover 132 form a second condensation area 133. The inner side surface of the condensation inner shell is formed with a guide rib.
