Along the circumference of the inner drum, the distance between the guide wall and the opening gradually changes.

[0008] In one embodiment, the maximum distance between the guide wall and the opening is 30 mm to 40 mm.

[0009] In one embodiment, the guide wall is arranged opposite to the opening.

[0010] In one embodiment, the condensation channel is arranged on the inner wall surface of the outer drum facing the inner drum and is located at the rear side of the inner drum, and the guide wall is inclined relative to the height direction of the clothing processing device.

[0011] In one embodiment, the angle between the guide wall and the height direction is 20° to 30°.

[0012] In one embodiment, the guide channel extends along the circumference of the inner tube, and the air inlet area is arranged at one end of the guide channel.

[0013] In one embodiment, an end wall of the guide channel close to one end of the air inlet area is a partition wall, and the partition wall extends along a first direction. The cylinder assembly further comprises a support frame, and the inner cylinder is rotatably supported on the outer cylinder by the support frame, and the support frame comprises a plurality of supports evenly spaced along the circumference of the inner cylinder, and the side walls of each support along both sides of the circumference of the inner cylinder are respectively a first side wall and a second side wall, and in the process of the support frame rotating from the air inlet area to the guide channel, the first side wall and the second side wall sequentially pass over the opening;

[0014] When projected onto a plane perpendicular to the axial direction of the inner cylinder, when the first side wall of any of the brackets is rotated to a state where the projection of the first side wall coincides with the projection of one end of the partition wall along the first direction close to the rotation center of the inner cylinder, the extension direction of the first side wall is the second direction, and the first direction and the second direction are set at an angle.

[0015] In one implementation, an angle between the first direction and the second direction is 20° to 45°.

[0016] In one embodiment, the outer cylinder includes a cylinder body and a condensation cover plate, the inner cylinder is rotatably arranged in the cylinder body, the side of the cylinder body facing the inner cylinder is recessed to form a recessed area, the condensation cover plate is covered on the cylinder body and blocks a portion of the recessed area, the blocked portion of the recessed area constitutes the guide channel, and the unblocked portion of the recessed area constitutes the air inlet area.

[0017] In one embodiment, the condensation cover plate includes a main body and reinforcing ribs, wherein the main body covers the cylinder body and covers a portion of the recessed area, and the reinforcing ribs are arranged on a side of the main body facing the recessed area and are located at one end of the main body close to the air inlet area.

In addition, since the depth of the air inlet area gradually increases in the counterclockwise direction, the volume of the stirred airflow entering the air inlet area through the opening will gradually change when the parts on the inner barrel pass through the opening, which is conducive to improving the noise problem caused by the sudden change of the airflow volume. In other words, the barrel assembly of the embodiment of the present application is conducive to improving the noise problem of the clothing processing equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Please also read Figures 1 to 7 An embodiment of the present application provides a clothing processing device, which includes a housing 200 and a drum assembly according to any one embodiment of the present application.

[0040] It should be noted that the clothing processing device can be a drum washing machine with a drying function, or a washer-dryer, etc., and there is no limitation here.

[0041] The box 200 can be understood as the external frame structure of the laundry processing device, and its specific shape is not limited. Figure 1 As shown, the box body 200 is a roughly cubic structure, and the box body 200 is placed on the ground, and its stability is relatively better.

[0042] The barrel assembly is arranged in the box 200. In other words, the box 200 can provide a mounting base for the barrel assembly.

[0043] Please also read Figures 1 to 7 The embodiment of the present application also provides a drum assembly for a clothing processing device, wherein the drum assembly includes an outer drum 10 and an inner drum 20.

[0044] The inner drum 20 has a clothes processing chamber 20a. The clothes are washed and cared for in the clothes processing chamber 20a. Figure 1 As shown, one side of the laundry processing chamber 20a is opened to form a laundry loading port, through which a user can take in and put out laundry.

[0045] The outer cylinder 10 is provided with a condensation channel 10a. Condensate is introduced into the condensation channel 10a. The type of condensate is not limited. For example, it can be condensed water.

[0046] It should be noted that the specific position of the condensation channel 10a on the outer tube 10 is not limited. In some embodiments, the condensation channel 10a is arranged on the inner side wall of the outer tube 10 in the circumferential direction; Figures 2 to 4 As shown, the condensation channel 10a is arranged on the inner end surface of one axial end of the outer cylinder 10.

[0047] When drying clothes, the wet air flow in the clothes processing chamber 20a can flow into the condensation channel 10a, and under the action of the condensation liquid, the water vapor in the wet air flow releases heat and condenses. That is, after passing through the condensation channel 10a, the wet air flow can become a dry air flow.

[0048] Furthermore, the clothing processing device also includes a heating device, in which a heating element is provided, and the heating element can be, for example, a heating tube, which is electrically connected to the power supply assembly, so that electrical energy can be converted into thermal energy. The wet airflow passes through the condensation channel 10a to form a dry airflow, and the dry airflow passes through the heating device and is heated by the heating element to obtain a dry hot airflow. The dry hot airflow enters the clothing processing chamber 20a, exchanges heat and moisture with the wet clothes, absorbs moisture from the clothes, and the dry hot airflow gradually turns into a wet airflow, and the clothes gradually achieve a drying effect under the action of the dry hot airflow.

[0049] The inner drum 20 is rotatably disposed in the outer drum 10. The inner drum 20 can achieve functions such as washing and dehydrating clothes by rotating. In addition, when drying clothes, the inner drum 20 can also rotate, thereby improving the uniformity of the clothes drying effect.

[0050] The inner drum 20 and the outer drum 10 are coaxially arranged inside and outside, and holes can be provided on the side wall of the inner drum 20, so that the water in the outer drum 10 can enter the inner drum 20 through the holes of the inner drum 20 to wash the clothes in the clothing processing chamber 20a. At the same time, when the clothes in the clothing processing chamber 20a are dried, the dry hot air flow and the clothes in the clothing processing chamber 20a exchange heat and moisture to generate a humid air flow can also enter the space between the outer drum 10 and the inner drum 20 through the holes of the inner drum 20. In this embodiment, the inner drum 20 can also be called a perforated inner drum.

[0051] The condensation channel 10a includes a flow guiding channel 10aa and an air inlet area 10ab. The flow guiding channel 10aa is connected to the inner space of the outer tube 10 through the air inlet area 10ab.

[0052] The air inlet area 10ab is open to the side facing the inner cylinder 20 and forms an opening 10b. In other words, the opening 10b is directly opposite the inner cylinder 20, and during the rotation of the inner cylinder 20, the outer wall of the inner cylinder 20 will pass over the top of the opening 10b. It should be noted that the "top" here should be understood based on the surface where the opening 10b is located. The space inside the air inlet area 10ab is located below the opening 10b, and the space after passing through the opening 10b inside the air inlet area 10ab is above the opening 10b. Specifically, Figures 2 to 4 As shown, when the opening 10b is located on the inner end wall of one axial end of the outer cylinder 10, the space above the opening 10b is the space between the outer end surface of one axial end of the inner cylinder 20 and the inner end wall of one axial end of the outer cylinder 10.

[0053] After the humid air flow in the clothing processing chamber 20a enters the space between the outer drum 10 and the inner drum 20, it can enter the guide channel 10aa through the air inlet area 10ab.

[0054] Please refer to Figures 2 to 4 The side wall of the condensation channel 10a includes a guide wall 111, which is located at one end of the condensation channel 10a close to the opening 10b, and the distance between the guide wall 111 and the opening 10b gradually changes along the circumference of the inner tube 20. For example, when the condensation channel 10a is formed by surrounding side walls in four directions, the opening 10b is opened on one of the side walls, and the guide wall 111 is the side opposite to the side where the opening 10b is located, and the side walls on the other two sides are the two side walls adjacent to the side where the opening 10b is located.

[0055] It is understandable that the guide wall 111 may be entirely the side wall of the air inlet area 10ab; or part of it may be the side wall of the air inlet area 10ab and the other part of it may be the side wall of the guide channel 10aa. Figure 4 As shown, a portion of the guide wall 111 is a side wall of the air inlet area 10ab, and another portion is a side wall of the guide channel 10aa.

[0056] The circumferential direction of the inner cylinder 20 can be counterclockwise or clockwise. The specific situation of the gradual change in the distance between the guide wall 111 and the opening 10b needs to be understood based on whether the counterclockwise direction or the clockwise direction is used as a reference. For example, Figures 2 to 4 As shown, in the counterclockwise direction, the distance between the guide wall 111 and the opening 10b gradually increases, while in the clockwise direction, the distance between the guide wall 111 and the opening 10b gradually decreases.

[0057] The rotation direction of the inner cylinder 20 is a direction on the circumference of the inner cylinder 20. For example, it can be a counterclockwise direction or a clockwise direction.

[0058] In the embodiment of the present application, the direction in which the distance between the guide wall 111 and the opening 10b gradually increases can be consistent with the rotation direction of the inner drum 20 when the laundry processing device is in the dehydration mode. For example, when the laundry processing device is in the dehydration mode, the inner drum 20 rotates counterclockwise, then, along the counterclockwise direction, the distance between the guide wall 111 and the opening 10b gradually increases; for another example, when the laundry processing device is in the dehydration mode, the inner drum 20 rotates clockwise, then, along the clockwise direction, the distance between the guide wall 111 and the opening 10b gradually increases. It can be understood that when the laundry processing device is running in the dehydration mode, the rotation speed of the inner drum 20 is relatively high, and the noise generated is relatively large. Therefore, the direction in which the distance between the guide wall 111 and the opening 10b gradually increases is consistent with the rotation direction of the inner drum 20 when the laundry processing device is in the dehydration mode, so that when the laundry processing device is running under relatively harsh working conditions, the guide wall 111 can play a better noise reduction effect.

[0059] In the air inlet area 10a, the "distance between the guide wall 111 and the opening 10b" can be understood as the depth of the air inlet area 10ab. That is, along the circumference of the inner cylinder 20, the depth of the air inlet area 10ab gradually changes. It can be understood that the surface where the guide wall 111 is located is set at an angle with the direction perpendicular to the surface where the opening 10b is located. For example, Figures 2 to 4 As shown, when the opening 10 b is located on the inner end surface of the outer cylinder 10 in the axial direction, the direction perpendicular to the surface where the opening 10 b is located is the axial direction of the inner cylinder 20 .

[0060] Specifically, the distance needs to be measured in a direction perpendicular to the surface where the opening 10b is located. For example, the distance between the guide wall 111 and the opening 10b is as follows: Figure 4 Middle D 1 shown.

[0061] It should be noted that Figure 4 Middle D 1 The figure shows the distance between one position on the wall surface of the flow guide wall 111 and the opening 10 b .

[0062] In the related art, in order to ensure the drying effect of the clothes processing equipment, the opening of the air inlet area needs to be set to a larger size to meet the air intake. Based on the outer drum of this structure, when the clothes processing equipment runs the dehydration function, the inner drum rotates at a high speed, which causes the airflow at the opening to be relatively violently agitated. The airflow enters the air inlet area under the agitation and hits the side wall of the air inlet area, which causes the clothes processing equipment to generate a large noise.

[0063] In the barrel assembly of the embodiment of the present application, the side wall of the condensation channel 10a includes a guide wall 111, which is located at one end of the condensation channel 10a close to the opening 10b. Along the circumference of the inner barrel 20, the distance between the guide wall 111 and the opening 10b gradually changes. Taking the example that the distance between the guide wall 111 and the opening 10b gradually increases in the counterclockwise direction, when the inner drum 20 rotates at high speed in the counterclockwise direction and stirs the airflow, the airflow flows roughly in the counterclockwise direction through the opening 10b into the air inlet area 10ab, and the guide wall 111 forms a certain guiding effect on the airflow, thereby guiding the airflow into the guide channel 10aa, which is conducive to improving the rebound problem after the airflow hits the side wall of the air inlet area 10ab, that is, it can alleviate the collision between the rebounded airflow and the airflow stirred into the air inlet area 10ab, thereby helping to improve the problem of high noise caused by airflow oscillation caused by the collision of gases. In addition, since the depth of the air inlet area 10ab gradually increases in the counterclockwise direction, the volume of the stirred airflow entering the air inlet area 10ab through the opening 10b will gradually change when the parts on the inner drum 20 pass through the opening 10b in the counterclockwise direction, which is conducive to improving the noise problem caused by the sudden change of the airflow volume. In other words, the drum assembly of the embodiment of the present application is conducive to improving the noise problem of the clothing processing equipment.

[0064] See also Figures 2 to 4 In one embodiment, the maximum distance between the guide wall 111 and the opening 10b is 30 mm to 40 mm, for example, 30 mm, 31 mm, 32 mm, 33 mm, 34 mm, 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, 40 mm, etc.

[0065] For example, the maximum distance between the guide wall 111 and the opening 10b is as follows: Figure 4 Middle D max shown.

[0066] Specifically, Figures 2 to 4 As shown, in the embodiment where the distance between the guide wall 111 and the opening 10b gradually increases in the counterclockwise direction, the maximum distance D max It is generated at the downstream end of the guide wall 111 in the counterclockwise direction.

[0067] In this embodiment, on the one hand, D max will not be less than 30 mm, that is, it can ensure that the air inlet area 10ab has a sufficient depth, that is, the guide wall 111 has a sufficient inclination angle, which is conducive to ensuring the guiding effect of the guide wall 111 on the airflow, thereby better reducing noise; on the other hand, D max It will not be greater than 40 mm, and thus, the depth of the air inlet area 10ab will not be too large, so that the size of the outer drum 10 can be controlled within a reasonable range, which is conducive to ensuring the compactness of the clothing processing equipment.

[0068] See also Figures 2 to 4 In one embodiment, the guide wall 111 is arranged opposite to the opening 10b. One side of the air inlet area 10ab is opened to form the opening 10b, and the wall surface on the side opposite to the opening 10b is at least a part of the guide wall 111. After the airflow enters the air inlet area 10ab through the opening 10b, the wall surface on the side opposite to the opening 10b is formed as the windward surface 10c. In this embodiment, the side wall serving as the windward surface 10c is at least a part of the guide wall 111, thereby being able to better reduce noise.

[0069] Of course, the side walls in other directions of the air inlet area 10ab can also be formed as a part of the guide wall 111.

[0070] See also Figures 1 to 4 In one embodiment, the condensation channel 10a is located at the rear side of the inner drum 20, and the guide wall 111 is inclined relative to the height direction of the clothing processing device.

[0071] It should be noted that, in the embodiment of the present application, the side of the inner drum 20 where the clothing loading port is opened is the front side, and the side opposite to the front side is the rear side. Figure 1 and Figure 3 shown.

[0072] The height direction of the clothes processing device should be understood based on the clothes processing device in normal use. Figure 1 and Figure 3 shown.

[0073] like Figure 3 and Figure 4 As shown, the condensation channel 10a is arranged on the inner wall surface of the outer cylinder 10 facing the inner cylinder 20 and is located at the rear side of the inner cylinder 20, that is, on the end wall at one axial end of the outer cylinder 10. As a result, the outer cylinder 10 can be more conveniently provided with the condensation channel 10a, and at the same time, it is also convenient for the internal space of the aforementioned heating device to be connected with the condensation channel 10a.

[0074] See also Figure 5 The cylinder assembly also includes a support frame 30, which is generally arranged between the rear end of the inner cylinder 20 and the outer cylinder 10. The support frame 30 is connected to the drive shaft of the inner cylinder 20 to provide support force for the drive shaft to improve the stability of the drive shaft.

[0075] When the inner cylinder 20 rotates at high speed, the support frame 30 rotates synchronously with the inner cylinder 20, so as to pass through the opening 10b at high speed, stir the airflow and make the airflow enter the air inlet area 10ab roughly along the rotation direction of the inner cylinder 20. In this embodiment, the component of the inner cylinder 20 that rotates at high speed and stirs the airflow is the support frame 30.

[0076] In order to ensure the condensation effect of the condensation channel 10a on the humid airflow, a height difference is formed at both ends of the condensation channel 10a. The condensate enters the condensation channel 10a from the end with a higher height, so that it can flow downward under the action of gravity. The humid airflow enters the condensation channel 10a from the end with a lower height, and generates convective heat exchange with the condensate. Therefore, the air inlet area 10ab is generally arranged on the left or right side of the outer cylinder 10. Therefore, at the opening 10b, the tangent of the inner cylinder 20 is nearly parallel to the height direction, and the airflow flows along the rotation direction of the inner cylinder 20, that is, it flows along the tangent, that is, the airflow enters the air inlet area 10ab roughly along the height direction. In this embodiment, by tilting the guide wall 111 relative to the height direction of the clothing processing device, the guide wall 111 has a better guiding effect on the airflow when the airflow enters the air inlet area 10ab and flows to the guide channel 10aa, which is conducive to improving the noise problem at the opening 10b.

[0077] It should be noted that “left side” or “right side” needs to be understood based on the directions of “front side” and “rear side” mentioned above.

[0078] See also Figures 2 to 4 In one embodiment, the angle between the guide wall 111 and the height direction is 20° to 30°, for example, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, etc.

[0079] The included angle between the guide wall 111 and the height direction is as follows: Figure 4 As shown in α.

[0080] It can be understood that, under the condition that the length of the guide wall 111 extending in the height direction is constant, the larger α is, the greater the maximum distance D between the guide wall 111 and the opening 10b is. max The bigger.

[0081] In this embodiment, on the one hand, α will not be less than 20°, so that the guide wall 111 has a sufficient inclination angle, which is conducive to ensuring the guiding effect of the guide wall 111 on the airflow, thereby better improving the noise problem; on the other hand, α will not be greater than 30°, so that under the condition that the dimension of the guide wall 111 extending in the height direction is constant, the maximum distance D between the guide wall 111 and the opening 10b is max Nor will it be too large, that is, the overall size of the outer drum 10 along the front-to-back direction can be controlled within a reasonable range, which is beneficial to ensuring the compactness of the clothing processing device.

[0082] See also Figure 2 , Figure 5 and Figure 6The guide channel 10aa extends along the circumference of the inner tube 20, and the air inlet area 10ab is arranged at one end of the guide channel 10aa. Therefore, when the size of the guide channel 10aa in the height direction is constant, it is beneficial to increase the length of the guide channel 10aa, thereby improving the condensation effect of the condensation channel 10a on the humid airflow.

[0083] It should be noted that, the guide channel 10aa may have only a portion extending along the circumferential direction of the inner tube 20, while the other portion still extends along the height direction.

[0084] See also Figure 4 , Figure 5 and Figure 7 The end wall of the guide channel 10aa close to the air inlet area 10ab is a partition wall 121a, and the partition wall 121a extends along the first direction. Figure 5 Medium 1 direction shown.

[0085] The barrel assembly further includes a support frame 30, and the inner barrel 20 is rotatably supported on the outer barrel 10 by the support frame 30. Specifically, the support frame 30 is drivingly connected to the driving shaft of the inner barrel 20, and the support frame 30 can improve the stability of the inner barrel 20 driven by the driving shaft to rotate.

[0086] The support frame 30 includes a plurality of supports 31 evenly spaced along the circumference of the inner cylinder 20. For example, Figure 5 As shown, there are three brackets 31 , and the support frame 30 is a tripod.

[0087] The side walls of each bracket 31 along the circumferential sides of the inner tube 20 are respectively the first side wall 311 and the second side wall 312. When the bracket 30 rotates from the air inlet area 10ab to the air guide channel 10aa, the first side wall 311 and the second side wall 312 pass over the opening 10b in sequence. In other words, when the bracket 31 rotates, the first side wall 311 first passes over the opening 10b, and then the second side wall 312 passes over the opening.

[0088] When projected on a plane perpendicular to the axial direction of the inner cylinder 20, the first side wall 311 of any bracket 31 rotates to a state where the projection of the first side wall 311 coincides with the projection of the partition wall 121a along the first direction close to the rotation center of the inner cylinder 20, the extension direction of the bracket 31 is the second direction. For example, the second direction is Figure 5 Medium 2 direction shown.

[0089] That is, when the bracket 31 passes through the opening 10b and the projection of the first side wall 311 overlaps with the projection of the partition wall 121a on a plane perpendicular to the axial direction of the inner tube 20, the extension direction of the first side wall 311 in this state is the second direction.

[0090] The first direction and the second direction are arranged at an angle. In this embodiment, when the bracket 31 passes over the partition wall 121a, the size of the opening 10b between the partition wall 121a and the bracket 31 gradually decreases, that is, when the bracket 31 passes over the partition wall 121a, the volume of the airflow entering the air inlet area 10ab gradually changes, which is conducive to improving the problem that the volume of the airflow entering the air inlet area 10ab changes suddenly and generates a lot of noise when the bracket 31 passes over the partition wall 121a.

[0091] See also Figure 5 In one embodiment, the angle between the first direction and the second direction is 20° to 45°, for example, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 32°, 34°, 36°, 38°, 40°, 45°, etc.

[0092] For example, the angle between the first direction and the second direction is as follows: Figure 5 As shown in β.

[0093] In this embodiment, β is controlled between 20° and 45°. On the one hand, the rate of change of the air flow volume entering the air inlet area 10ab when the bracket 31 passes over the partition wall 121a is more appropriate, which is beneficial to controlling the amount of noise generated; on the other hand, the size of the opening 10b can also be controlled at an appropriate size, so that the extension length of the guide channel 10aa in the condensation channel 10a is longer, which is beneficial to improving the heat exchange performance of the condensation channel 10a.

[0094] See also Figure 6 In one embodiment, the outer cylinder 10 includes a cylinder body 11 and a condensation cover plate 12, the inner cylinder 20 is rotatably arranged in the cylinder body 11, the side of the cylinder body 11 facing the inner cylinder 20 is recessed to form a recessed area 11a, the condensation cover plate 12 is covered on the cylinder body 11 and blocks part of the recessed area 11a, the blocked part of the recessed area 11a constitutes a guide channel 10aa, and the unblocked part of the recessed area 11a constitutes an air inlet area 10ab.

[0095] The guide wall 111 is the side wall of the recessed area 11 a .

[0096] It can be understood that the side of the cylinder body 11 facing the inner cylinder 20 is recessed to form a recessed area 11a, and the side of the recessed area 11a facing the inner cylinder is formed into an opening, the condensation cover plate 12 covers the opening and blocks a part of the opening, and the area not blocked by the opening forms an opening 10b.

[0097] In this embodiment, the end wall of the condensation cover plate 12 close to the air inlet area 10ab is the partition wall 121a, and the partition wall 121a divides the condensation channel 10a into the guide channel 10aa and the air inlet area 10ab. The partition wall 121a can be understood as the end wall of the guide channel 10aa close to the air inlet area 10ab.

[0098] The barrel 11 and the condensation cover plate 12 are split structures. During the production process of the barrel 11, the recessed area 11a is equivalent to having an open side, so as to facilitate demolding. Then, a part of the recessed area 11a is covered by the condensation cover plate 12, so that the guide channel 10aa and the air inlet area 10ab can be formed. In other words, the outer barrel 10 of this embodiment, on the premise of being able to form the guide channel 10aa, is also conducive to demolding of various components of the outer barrel 10.

[0099] See also Figures 2 to 4 and 7. In one embodiment, the condensation cover plate 12 includes a main body 121 and a reinforcing rib 122. The main body 121 is covered on the barrel 11 and covers a portion of the recessed area 11a. The reinforcing rib 122 is provided on a side of the main body 121 facing the recessed area 11a and is located at one end of the main body 121 close to the air inlet area 10ab.

[0100] The body 121 and the reinforcing rib 122 may be an integrated structure, that is, the reinforcing rib 122 may be formed by a protrusion of a side wall of the condensation cover plate 12 .

[0101] Of course, the main body 121 and the reinforcing ribs 122 may also be separate structures.

[0102] By providing reinforcing ribs 122 on the main body 121, it is helpful to improve the overall structural strength of the condensation cover plate 12. When the airflow flows in the guide channel 10aa, it is helpful to reduce the probability of shaking of the condensation cover plate 12, thereby helping to improve the noise problem caused by the shaking of the condensation cover plate 12. At the same time, after the structural strength of the condensation cover plate 12 is improved, it is also helpful to improve the reliability of the cylinder assembly, thereby improving the user experience.

[0103] See also Figure 7 In one embodiment, the reinforcing rib 122 extends along the first direction, and the protruding dimension of any end of the reinforcing rib 122 relative to the main body 121 along the first direction is greater than the protruding dimension of the middle area of ​​the reinforcing rib 122 relative to the main body 121 along the first direction.

[0104] It is understandable that after the airflow enters the air inlet area 10ab, it will flow into the guide channel 10aa after being guided by the guide wall 111. The reinforcing ribs 122 are located on the flow path of the airflow, which will produce a certain obstruction to the flow of the airflow.

[0105] In this embodiment, the regions at both ends of the reinforcing ribs 122 along the first direction retain a larger size, which is beneficial to ensuring the overall structural strength of the condensation cover 12. At the same time, the protruding size of the middle region of the reinforcing ribs 122 along the first direction relative to the main body 121 is reduced as much as possible, thereby minimizing the problem of blocking the airflow caused by the reinforcing ribs 122, which is beneficial to improving the noise problem of the clothing processing equipment.

[0106] See also Figures 2 to 4 In one embodiment, the protrusion of the reinforcing rib 122 relative to the main body 121 in the middle area along the first direction is 2 mm to 10 mm, for example, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.

[0107] For example, the size of the reinforcement rib 122 protruding relative to the main body 121 in the middle region along the first direction is as follows: Figure 4 Middle D 2 shown.

[0108] In this embodiment, on the one hand, D 2 The size of D will not be less than 2 mm, so that to a certain extent, the reinforcing rib 122 can strengthen the overall structural strength of the condensation cover plate 12; on the other hand, D 2 The size will not be greater than 10 mm, so the reinforcing rib 122 has a relatively small blocking effect on the airflow, and the noise generated by the airflow passing through the reinforcing rib 122 is relatively low.

[0109] See also Figure 2 In one embodiment, the distance between the condensation channel 10a and the rotation center of the inner cylinder 20 along the radial direction of the outer cylinder 10 is the first dimension, the radius of the outer cylinder 10 is the second dimension, and the ratio of the first dimension to the second dimension is 1 / 2 to 3 / 4. That is, the first dimension accounts for 0.5 to 0.75 of the second dimension, for example, 0.5, 0.51, 0.52, 0.53, 0.54, 0.55, 0.56, 0.57, 0.58, 0.59, 0.6, 0.62, 0.64, 0.66, 0.68, 0.7, 0.75, etc.

[0110] For example, the first size is Figure 2 Middle D 3 shown.

[0111] The two ends of the condensation channel 10a are connected to the rotation center of the inner cylinder 20. It can be understood that, under the condition that the angle between the two connecting lines is constant, the larger the ratio of the first dimension to the second dimension, the larger the extension length of the condensation channel 10a, thereby facilitating the improvement of the heat exchange effect of the condensation channel 10a on the humid airflow.

[0112] In this embodiment, on the one hand, the ratio of the first size to the second size will not be less than 1 / 2, which is conducive to ensuring the heat exchange effect of the condensation channel 10a; on the other hand, the ratio of the first size to the second size will not be greater than 3 / 4, so that the opening 10b will not be too close to the outer peripheral side of the outer cylinder 10, thereby facilitating the moisture flow through the opening 10b into the air inlet area 10ab.
