Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a clothing processing device. Background Art

[0002] Laundry processing equipment such as drum washing machines are household appliances that use electrical energy to generate mechanical action to dry clothes. As consumers' living standards improve, their requirements for laundry processing equipment are also getting higher and higher.

[0003] In related laundry processing devices, such as drum washing machines, the laundry processing device typically comprises a housing, an inner drum, and an outer drum. The inner and outer drums are located within the housing. The inner drum contains a laundry processing chamber for placing laundry to be processed. The inner drum is rotatable relative to the outer drum. During the laundry drying process, the hot and humid air generated in the inner drum flows into the outer drum and condenses on the rear wall of the outer drum, thereby condensing the hot and humid air in the outer drum.

[0004] In existing clothing processing equipment, since the surface between the inner drum and the outer drum is relatively flat, when the inner drum rotates relative to the outer drum, the hot and humid air inside the outer drum cannot be controlled to flow efficiently to the rear wall of the outer drum, thereby resulting in poor condensation efficiency of the hot and humid air in the inner and outer drums of the existing clothing processing equipment. Utility Model Content

[0005] The purpose of the present utility model is to provide a clothes processing device to optimize the structure of the clothes processing device in the related art and to improve the condensation efficiency of the hot and humid air in the outer drum.

[0006] The purpose of the present invention is not limited to the above-mentioned purpose, and those skilled in the art can clearly understand other purposes not mentioned through the following description.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] According to one aspect of the present invention, the present invention provides a clothing processing device, comprising: a casing, which is configured as the outer shell of the clothing processing device; a drum assembly, which is arranged inside the casing; the drum assembly includes an outer drum and an inner drum arranged inside the outer drum; a clothing processing device is provided inside the inner drum, and the inner drum can rotate relative to the outer drum; a fixed frame, which is fixed to the rear wall of the inner drum; wherein the fixed frame has a plurality of fan blades protruding and extending toward the rear wall of the outer drum; when the inner drum rotates relative to the outer drum, the fixed frame can drive the plurality of fan blades to rotate, thereby driving the flow of air around the plurality of fan blades, so that the hot and humid air in the outer drum flows toward the rear wall of the outer drum.

[0009] One of the above technical solutions has the following advantages or beneficial effects: when the inner drum rotates relative to the outer drum, the fixed frame can drive the fan blade part to rotate, thereby driving the flow of air around the fan blade part, so that the hot and humid air in the outer drum flows to the rear wall of the outer drum, that is, the flow of hot and humid air in the outer drum can be made directional, so that the hot and humid air in the outer drum can be quickly transferred to the rear wall of the outer drum, thereby improving the condensation efficiency of the hot and humid air in the outer drum, and thereby improving the drying efficiency of the clothing processing equipment.

[0010] In some embodiments of the present application, the fixing frame includes a plurality of fixing arms, and the plurality of fixing arms are arranged at intervals on the rear wall of the inner cylinder; a flange is provided on one side of the inner rear wall of the inner cylinder close to the outer cylinder, and the flange is arranged around the circumference of the rear wall of the inner cylinder; the inner ends of the plurality of fixing arms are interconnected at the center of the rear wall of the inner cylinder, and the plurality of fixing arms are extended from the center of the rear wall of the inner cylinder toward the circumferential edge of the rear wall of the inner cylinder; the fan blade portion is extended from the fixing arm toward the direction of the flange.

[0011] One of the above technical solutions has the following advantages or beneficial effects: by providing multiple fixed arms spaced apart on the flange of the inner tube, the multiple fixed arms can simultaneously provide support for the rear wall of the inner tube when the inner tube rotates, thereby increasing the support strength of the fixed frame for the inner tube during rotation. By extending the fan blade portion toward the rear wall of the outer tube, the rear end of the fan blade portion protrudes beyond the rear end of the fixed arms. When the inner tube rotates relative to the outer tube, the fixed frame on the rear wall of the inner tube can drive the fan blade portion to rotate, thereby driving the flow of air around the fan blade portion, thereby allowing the hot and humid air in the outer tube to quickly flow to the rear wall of the outer tube, thereby increasing the condensation efficiency of the hot and humid air in the outer tube.

[0012] In some embodiments of the present application, the fan blade portion is provided on the edge of the fixed arm, and the fan blade portion protrudes and extends from the edge of the fixed arm toward the rear wall of the outer cylinder.

[0013] One of the above technical solutions has the following advantages or beneficial effects: by arranging the fan blades at the edge of the fixed arm, the connection between the fan blades and the fixed arm can be smoother. By arranging the fan blades at the edge of the fixed arm, the fan blades can be staggered with the fixed arm. When the inner cylinder rotates relative to the outer cylinder, the fixed arm drives the fan blades to rotate, which can increase the air volume generated by the fan blades, thereby allowing the hot and humid air in the outer cylinder to flow quickly to the rear wall of the outer cylinder, thereby improving the condensation efficiency of the hot and humid air in the outer cylinder.

[0014] In some embodiments of the present application, the fan blade portion is in the shape of an elongated strip, and the length extension direction of the fan blade portion is the same as the extension direction of the fixed arm.

[0015] One of the above technical solutions has the following advantages or beneficial effects: the fan blade portion is in a long strip shape, and the length extension direction of the fan blade portion is the same as the extension direction of the fixed arm, so that the fan blade portion can drive a larger air area, so that more humid and hot air in the outer tube can flow to the rear wall of the outer tube faster, so that the humid and hot air in the outer tube can be transferred to the rear wall of the outer tube faster, thereby improving the condensation efficiency of the humid and hot air in the outer tube.

[0016] In some embodiments of the present application, the length of the fan blade portion is at least greater than half the length of the fixed arm.

[0017] One of the above technical solutions has the following advantages or beneficial effects: when the inner cylinder rotates relative to the outer cylinder, the fixed frame on the rear wall of the inner cylinder can drive the fan blade portion to rotate, so that the fan blade portion can drive the flow of air around the fan blade portion. By utilizing the length of the fan blade portion being greater than half the length of the fixed arm, the air area driven by the fan blade portion can be increased, thereby ensuring that the rotation of the fan blade portion can drive more air toward the rear wall of the outer cylinder. If the length of the fan blade portion is less than half the length of the fixed arm, the area of air flow driven by the fan blade portion will be small, so that the fan blade portion cannot fully drive the hot and humid air in the outer cylinder toward the rear wall of the outer cylinder, so that the hot and humid air in the outer cylinder cannot be quickly transferred to the rear wall of the outer cylinder, thereby affecting the condensation efficiency of the hot and humid air in the outer cylinder.

[0018] In some embodiments of the present application, the middle portion of the fan blade portion protrudes and extends in an arc shape toward the rear wall of the outer cylinder.

[0019] One of the above technical solutions has the following advantages or beneficial effects: the middle part of the fan blade part is extended in an arc shape toward the rear wall of the outer tube, and then when the inner tube drives the fan blade part to rotate, the protruding part of the fan blade part pushes the air toward the rear wall of the outer tube, so that a pressure difference is formed on both sides of the fan blade part, thereby forming an airflow flowing toward the rear wall of the outer tube, so that the hot and humid air in the outer tube can be quickly blown toward the rear wall of the outer tube, thereby improving the condensation efficiency of the hot and humid air in the outer tube.

[0020] In some embodiments of the present application, the fan blade portion is arranged to extend obliquely from the fixed arm toward the direction close to the rear wall of the outer cylinder.

[0021] One of the above technical solutions has the following advantages or beneficial effects: the fan blade portion is arranged to extend obliquely toward the rear wall of the outer cylinder, and when the inner cylinder drives the fan blade portion to rotate, the fan blade portion can push the air toward the rear wall of the outer cylinder, so that a pressure difference is formed on both sides of the fan blade portion, thereby forming an airflow flowing toward the rear wall of the outer cylinder, and then the hot and humid air in the outer cylinder can be quickly blown toward the rear wall of the outer cylinder, thereby improving the condensation efficiency of the hot and humid air in the outer cylinder.

[0022] In some embodiments of the present application, a rotating shaft is provided between the outer cylinder and the inner cylinder, one end of the rotating shaft is rotatably provided on the outer cylinder, and the other end of the rotating shaft is connected to the inner cylinder; the surface at the connection between the fixing frame and the rotating shaft is a first connecting surface, the edge of the first connecting surface close to the inner rear wall of the outer cylinder is a first connecting line, and the plane where the first connecting line is located is a first reference plane; one of the fixed arms is a first fixed arm, the fan blade portion provided on the first fixed arm is a first fan blade portion, and at least one mounting hole is provided on the first fixed arm, and the first fixed arm is connected to the flange through the mounting hole; the axis of the inner cylinder is a first axis, and the first axis is aligned with the first axis. The intersection of a reference plane is the first axis point a, the axis of the mounting hole close to the first fan blade part is the second axis point, the intersection of the second axis point and the side wall of the flange close to the fixed arm is the second axis point b, the vertical projection point of the second axis point on the first reference plane is the first projection point c, and the line connecting the first axis point and the first projection point is the first reference line; the point of the first fan blade part farthest from the first reference plane is the first reference point d, the intersection of the first reference point and the first reference line perpendicular to the first reference line is the first intersection point e, and the angle between the line connecting the first reference point and the first intersection and the first plane is α, and α satisfies 15°<α<75°.

[0023] One of the above technical solutions has the following advantages or beneficial effects: by utilizing the angle range of α between 15 degrees and 75 degrees, when the inner cylinder drives the first blade portion to rotate, the airflow of the hot and humid air driven by the first blade portion can reach the rear wall of the outer cylinder faster, thereby improving the condensation efficiency of the hot and humid air in the outer cylinder. If the angle of α is less than 15 degrees, when the inner cylinder drives the first blade portion to rotate, due to the small angle deviation between the first blade portion and the first fixed arm, the airflow toward the rear wall of the outer cylinder formed when the first blade portion rotates is small, thereby making the hot and humid air in the outer cylinder unable to be quickly transferred to the rear wall of the outer cylinder, thereby affecting the condensation efficiency of the hot and humid air in the outer cylinder. If the angle of α is greater than 75 degrees, when the inner cylinder drives the first blade portion to rotate, the first blade portion is subjected to large resistance, so that the first blade portion requires more power.

[0024] In some embodiments of the present application, the plurality of fixing arms include at least three, and the three fixing arms are arranged at intervals on the rear wall of the outer cylinder.

[0025] One of the above technical solutions has the following advantages or beneficial effects: at least three fixed arms are provided, and the three fixed arms are arranged at intervals on the rear wall of the inner cylinder, so that the three fixed arms can simultaneously provide support for the rear wall of the inner cylinder when the inner cylinder rotates, thereby increasing the support strength of the fixed frame for the inner cylinder during rotation by providing three fixed arms.

[0026] In some embodiments of the present application, the fixing frame further includes a connecting portion, which is provided at the center of the rear wall of the outer cylinder, and the plurality of fixing arms are arranged around the connecting portion at intervals, and the plurality of fixing arms extend from the connecting portion toward the peripheral edge of the rear wall of the inner cylinder.

[0027] One of the above technical solutions has the following advantages or beneficial effects: the connecting part is arranged at the center of the rear wall of the inner drum, and multiple fixed arms are arranged at intervals around the circumference of the connecting part. When the motor is working, the motor can drive the connecting part and the fixed arms to rotate stably, thereby causing the inner drum to rotate relative to the outer drum to achieve cleaning of the clothes in the clothing processing cavity of the inner drum.

[0028] In some embodiments of the present application, a mounting groove is provided forwardly on the back side of the rear wall of the inner cylinder, and the fixing frame is installed in the mounting groove; the rear end of the fan blade portion protrudes out of the mounting groove; and a gap is provided between the fan blade portion and the side wall of the mounting groove.

[0029] One of the above technical solutions has the following advantages or beneficial effects: a mounting groove is provided on the back side of the rear wall of the inner cylinder, and the fixing bracket is installed in the mounting groove, so that the fixing bracket can be stably installed on the rear wall of the inner cylinder through the mounting groove; and a gap is provided between the fan blade part and the side wall of the mounting groove. When the inner cylinder drives the fan blade part to rotate, the pressure of the fan blade part at the gap is lower than the pressure on the side of the fan blade part close to the rear wall of the outer cylinder, so that the air in the gap can be blown toward the rear wall of the outer cylinder, thereby improving the condensation efficiency of the hot and humid air in the outer cylinder.

[0030] In some embodiments of the present application, a plurality of bosses are provided on the back side of the rear wall of the inner drum, and air outlet holes are respectively provided on the top surfaces of the plurality of bosses; the hot and humid air in the clothing processing chamber can enter the outer drum through the air outlet holes; the rear end of the fan blade part protrudes out of the top surface of the boss; and the mounting groove is formed between the plurality of bosses.

[0031] One of the above technical solutions has the following advantages or beneficial effects: the air outlet can be used to make the hot and humid air in the inner drum flow into the outer drum, so that the hot and humid air in the clothing processing chamber can enter the condensation chamber through the air outlet; by providing multiple bosses, the hot and humid air in the clothing processing chamber can enter the condensation chamber through the air outlet on multiple bosses at the same time, and thus the efficiency of the hot and humid air in the clothing processing chamber to flow to the condensation chamber can be improved through multiple bosses.

One end of the rotating shaft 5 is rotatably connected to the rear end of the outer cylinder 2. The other end of the rotating shaft 5 can be used to connect to the rear end of the inner cylinder 3.

[0075] In some embodiments, the laundry processing device may include a motor (not shown). The motor may be located outside the outer drum 2. The driving end of the motor may be connected to the end of the rotating shaft 5 that is away from the inner drum 3.

The outer ends of the three fixing arms 62 may be fixedly connected to the edges of the rear wall of the inner cylinder 3, respectively. The three fixing arms 62 can increase the support strength of the fixing frame 6 on the rear wall of the inner cylinder 3 during rotation.

[0084] It should be noted that, in some other embodiments, there may be more than three fixed arms 62 , which is not limited here.

[0085] In some embodiments, three fixed arms 62 can be arranged evenly spaced circumferentially on the rear wall of the inner cylinder 3, so that the stability of the support provided by the fixed arms 62 to the rear wall of the inner cylinder 3 can be improved during the rotation of the inner cylinder 3 relative to the outer cylinder 2.

[0086] See also Figure 9 and Figure 10 As shown, in some embodiments, a flange 34 may extend from the edge of the rear surface of the rear wall of the inner cylinder 3 toward the rear wall of the outer cylinder 2.

[0088] In some embodiments, the fixed arm 62 may be provided with a plurality of first mounting holes. The plurality of first mounting holes may be spaced apart and their axial directions may be parallel to one another. The flange 34 may be provided with a plurality of second mounting holes. The plurality of first mounting holes and the plurality of second mounting holes may be arranged in a one-to-one correspondence. The plurality of first mounting holes and the plurality of second mounting holes may be arranged in a coordinated manner to improve the connection stability between the fixed arm 62 and the flange 34, and thereby improve the connection stability between the fixed arm 62 and the inner cylinder 3.

[0089] See also Figures 6 to 12As shown, in some embodiments, a mounting groove 32 may be provided on the rear wall of the inner tube 3. The mounting groove 32 may be formed by a forward recessed portion of the rear surface of the rear wall of the inner tube 3. The fixing bracket 6 may be adapted to fit within the mounting groove 32.

[0090] In some embodiments, a boss 33 is provided on the back side of the rear wall of the inner tub 3. The surface of the boss 33 facing the outer tub 2 may be provided with an air outlet 331. The air outlet 331 connects the laundry processing chamber 31 and the condensation chamber. The hot and humid air in the laundry processing chamber 31 can enter the outer tub 2 through the air outlet 331. The hot and humid air in the laundry processing chamber 31 can also enter the condensation chamber through the air outlet 331.

[0091] It should be noted that, in some other embodiments, the air outlet 331 may also be provided on the side wall of the boss 33 .

[0092] In some embodiments, there may be multiple air outlets 331. The hot and humid air in the laundry processing chamber 31 can simultaneously enter the outer tub 2 through the multiple air outlets 331, thereby improving the efficiency of the hot and humid air in the laundry processing chamber 31 flowing into the outer tub 2.

[0093] In some embodiments, multiple bosses 33 may be provided. Multiple bosses 33 may be spaced apart and arranged around the circumference of the rotating shaft of the inner drum 2. A mounting groove 32 may be formed between two adjacent bosses 33. Each of the multiple bosses 33 is provided with an air outlet 331. The hot and humid air within the laundry processing chamber 31 can simultaneously enter the condensing chamber through the air outlet 331 on the multiple bosses 33, and then pass through the multiple bosses 33, thereby improving the efficiency of the hot and humid air flowing from the laundry processing chamber 31 to the condensing chamber.

[0094] In some embodiments, three bosses 33 may be provided. The three bosses 33 may be spaced apart and arranged around the circumference of the rotating shaft of the inner cylinder 2. Mounting slots 32 may be formed between two adjacent bosses 33. The three bosses 33 may have three mounting slots 32 formed therein. The number of mounting slots 32 may correspond to the number of fixed arms 62.

[0095] It should be noted that, in some other embodiments, the number of bosses 33 and mounting slots 32 may also be adjusted according to the number of fixing arms 62 .

[0096] See also Figures 6 to 12As shown, in some embodiments, a fan blade portion 63 may be provided on the fixing frame 6. The fan blade portion 63 may be provided to protrude and extend from the fixing frame 6 toward the rear wall of the outer cylinder 2. The fan blade portion 63 may be provided to protrude and extend from the fixing frame 6 toward the condensation pan 22. When the inner cylinder 3 rotates relative to the outer cylinder 2, the fixing frame 6 on the rear wall of the inner cylinder 3 can drive the fan blade portion 63 to rotate, thereby driving the flow of air around the fan blade portion 63, so that the hot and humid air in the outer cylinder 2 can flow to the rear wall of the outer cylinder 2, thereby making the flow of the hot and humid air in the outer cylinder 2 directional, so that the hot and humid air in the outer cylinder 2 can be quickly transferred to the rear wall of the outer cylinder 2, thereby improving the condensation efficiency of the hot and humid air in the outer cylinder 2.

[0097] In some embodiments, the fan blade portion 63 can be arranged to protrude and extend from the fixed arm 62 toward the rear wall of the outer drum 2. When the inner drum 3 rotates relative to the outer drum 2, the inner drum 3 can drive the fixed arm 62 to rotate, and the fixed arm 62 can drive the fan blade portion 63 to rotate, thereby driving the flow of air around the fan blade portion 63, so that the hot and humid air in the outer drum 2 can flow toward the rear wall of the outer drum 2, thereby making the flow of the hot and humid air in the outer drum 2 directional, so that the hot and humid air in the outer drum 2 can be quickly transferred to the rear wall of the outer drum 2, thereby improving the condensation efficiency of the hot and humid air in the outer drum 2, and thus improving the drying efficiency of the clothes processing device.

[0098] It should be noted that, in some other embodiments, the fan blade portion 63 may also be provided to protrude and extend from the connecting portion 61 toward the rear wall of the outer tube 2 .

[0099] In some embodiments, the fan blade portion 63 can be provided on the edge of the fixed arm 62. The fan blade portion 63 can be provided to protrude from the edge of the fixed arm 62 toward the rear wall of the outer tube 2.

[0100] It should be noted that, in some other embodiments, the fan blade portion 63 may also be provided to protrude and extend from the middle portion or other areas of the fixed arm 62 toward the rear wall of the outer tube 2 .

[0101] In some embodiments, the rear end of the fan blade portion 63 can protrude out of the mounting slot 32. The rear end of the fan blade portion 63 can protrude beyond the surface of the boss 33 near the rear wall of the outer tube 2. A gap 321 can be provided between the fan blade portion 63 and the sidewall of the mounting slot 32. When the inner tube 3 drives the fan blade portion 63 to rotate, the pressure of the fan blade portion 63 at the gap 321 is lower than the pressure on the side of the fan blade portion 32 near the rear wall of the outer tube 2, thereby blowing the air at the gap 321 toward the rear wall of the outer tube 2, thereby improving the condensation efficiency of the hot and humid air in the outer tube 2.

[0102] In some embodiments, the fan blade portion 63 can be in the shape of an elongated strip. The fan blade portion 63 can extend along the edge of the fixed arm 62 toward the peripheral edge of the inner drum 3. The length extension direction of the fan blade portion 63 can be the same as the extension direction of the fixed arm 62, thereby allowing the fan blade portion 63 to drive the flow speed of the air over an increased area, thereby enabling the hot and humid air in the outer drum 2 to flow to the rear wall of the outer drum 2 faster, allowing the hot and humid air in the outer drum 2 to be transferred to the rear wall of the outer drum 2 faster, thereby improving the condensation efficiency of the hot and humid air in the outer drum 2, and thereby improving the drying efficiency of the clothes processing device.

[0103] In some embodiments, the length of the fan blade portion 63 can be at least greater than half the length of the fixed arm 62, so as to increase the air area that the fan blade portion 63 can drive, thereby ensuring that the rotation of the fan blade portion 63 can drive more air to move toward the rear wall of the outer tube 2.

[0104] In some embodiments, if the length of the fan blade portion 63 is less than half the length of the fixed arm 62, the area of air flow driven by the fan blade portion 63 will be small, so that the fan blade portion 63 cannot fully drive the hot and humid air in the outer tube 2 to move toward the rear wall of the outer tube 2, so that the hot and humid air in the outer tube 2 cannot be quickly transferred to the rear wall of the outer tube 2, thereby affecting the condensation efficiency of the hot and humid air in the outer tube 2.

[0105] See also Figure 10 As shown, in some embodiments, the fan blade portion 63 can be arranged to extend obliquely from the fixed arm 62 toward the direction close to the rear wall of the outer tube 2. The fan blade portion 63 can be arranged to extend obliquely toward the direction of the adjacent boss 33. The fan blade portion 63 can be arranged above the interval 321. When the inner tube 3 drives the fan blade portion 63 to rotate, the fan blade portion 63 can push the air toward the rear wall of the outer tube 2, so that a pressure difference is formed on both sides of the fan blade portion 63, thereby forming an airflow flowing toward the rear wall of the outer tube 2, and then the hot and humid air entering the outer tube 2 can be quickly blown toward the rear wall of the outer tube 2, that is, the hot and humid air entering the outer tube 2 can be blown toward the condensation plate 22, thereby improving the condensation efficiency of the hot and humid air in the outer tube 2, and then improving the drying efficiency of the clothing processing equipment.

[0107] See also Figures 13 to 15As shown, in some embodiments, a first connection surface may be provided at the connection between the fixing bracket 6 and the rotating shaft 5. The first connection surface may be provided on the side of the connection hole that is close to the rear wall of the outer cylinder 2. The first connection surface may be circular. The edge of the first connection surface close to the inner rear wall of the outer cylinder 2 may be a first connection line. The plane on which the first connection line lies may be a first reference plane 7. The first reference plane 7 may be parallel to the first connection surface. The first reference plane 7 may be parallel to the plane on which the inner rear wall of the outer cylinder 2 lies. The first reference plane 7 may be parallel to the plane on which the rear wall of the inner cylinder 3 lies.

[0108] It should be noted that, in some other embodiments, the first connecting surface may be square or in other shapes.

[0109] In some embodiments, one of the three fixed arms 62 may be a first fixed arm 621. The first fixed arm 621 may be provided with a first blade portion 631. The first blade portion 631 may be provided on a side edge of the first fixed arm 621. The first blade portion 631 may extend from the edge of the first fixed arm 621 toward the inner rear wall of the outer tube 2.

[0110] See also Figures 13 to 15 As shown, in some embodiments, the inner cylinder 3 may be provided with a first axis aa. The first axis aa may be the central axis of the inner cylinder 3. The first axis aa may be colinear with the rotating shaft 5. The intersection of the first axis aa and the first reference plane 7 may be a first axis point a. The axis near the first mounting hole of the first blade portion 631 may be a second axis bb. A second axis point b may be provided on the second axis bb. The second axis point b may be the intersection of the second axis bb and the side wall of the flange 34 near the first fixed arm 621. The vertical projection of the second axis point b on the first reference plane 7 may be a first projection point c. The line connecting the first axis point b and the first projection point c may be a first reference line cc. The first reference line cc may be provided on the first reference plane 7. The first blade portion 631 may be provided with a first reference point d. The first reference point d may be the point of the first blade portion 631 farthest from the first reference plane 7. The first reference point d may be the point of the first blade portion 631 closest to the rear wall of the outer cylinder 2. The intersection of the first reference point d and the first reference line cc can be a first intersection point e. The first intersection point e can be the projection point of the first reference point d on the first reference line cc. The angle between the line between the first reference point d and the first intersection point e and the first reference plane 7 can be α.

[0111] In some embodiments, the angle α can be greater than 15 degrees, so that when the inner tube 3 drives the first fan blade portion 631 to rotate, the airflow of the humid and hot air driven by the first fan blade portion 631 can reach the rear wall of the outer tube 2 faster, thereby improving the condensation efficiency of the humid and hot air in the outer tube 2.

[0112] In some embodiments, the angle α can be less than 75 degrees, so that when the inner tube 3 drives the first fan blade portion 631 to rotate, the airflow of the humid and hot air driven by the first fan blade portion 631 can reach the rear wall of the outer tube 2 faster, thereby improving the condensation efficiency of the humid and hot air in the outer tube 2.

[0113] In some embodiments, the angle α can be between 15 degrees and 75 degrees, so that when the inner tube 3 drives the first fan blade portion 631 to rotate, it can not only ensure that the distance of the air flow driven by the first fan blade portion 631 reaches the rear wall of the outer tube 2, but also enable the airflow of the humid and hot air driven by the first fan blade portion 631 to reach the rear wall of the outer tube 2 faster, thereby improving the condensation efficiency of the humid and hot air in the outer tube 2.

[0114] In some embodiments, if the angle α can be less than 15 degrees, when the inner tube 3 drives the first fan blade portion 631 to rotate, due to the small angle deviation between the first fan blade portion 631 and the first fixed arm 621, the air volume formed by the first fan blade portion 631 when rotating toward the rear wall of the outer tube 2 is small, and the hot and humid air in the outer tube 2 cannot be quickly transferred to the rear wall of the outer tube 2, thereby affecting the condensation efficiency of the hot and humid air in the outer tube 2.

[0115] In some embodiments, if the angle α is greater than 75 degrees, when the inner cylinder 3 drives the first fan blade portion 631 to rotate, the first fan blade portion 631 encounters greater resistance, so that the first fan blade portion 631 requires greater rotational power, thereby requiring greater driving force and placing higher requirements on the motor.

[0116] It should be noted that in some embodiments, one of the three fixed arms 62 may be a second fixed arm. The second fixed arm may be provided with a second blade portion. The second blade portion may be provided on a side edge of the second fixed arm. The second blade portion may extend from the edge of the second fixed arm toward the inner rear wall of the outer tube 2.

[0117] In some embodiments, the axis of the first mounting hole near the second blade portion may be a third axis. A third axis center point may be provided on the third axis. The third axis center point may be the intersection of the third axis and the side wall of the flange near the second fixed arm. The vertical projection point of the third axis center point on the first reference plane 7 may be the second projection point. The line connecting the first axis center point b and the second projection point may be the second reference line. The second reference line may be provided on the first reference plane 7. A second reference point may be provided on the second blade portion. The second reference point may be the point on the second blade portion farthest from the first reference plane 7. The second reference point may be the point closest to the rear wall of the outer cylinder 2 of the second blade portion. The intersection point of the second reference point perpendicular to the second reference line may be the second intersection point. The second intersection point may be the projection point of the second reference point on the second reference line. The angle between the line connecting the second reference point and the second intersection point and the first reference plane 7 may be β.

[0118] It should be noted that in some embodiments, the angle β can be the same as the angle α. The angle β can be between 15 degrees and 75 degrees. Thus, when the inner cylinder 3 drives the second fan blade unit to rotate, it can ensure that the air flow driven by the second fan blade unit reaches the rear wall of the outer cylinder 2, and the hot and humid air flow driven by the second fan blade unit can reach the rear wall of the outer cylinder 2 more quickly, thereby improving the condensation efficiency of the hot and humid air in the outer cylinder 2.

[0119] It should be noted that in some embodiments, one of the three fixed arms 62 may be a third fixed arm. The third fixed arm may be provided with a third fan blade portion. The third fan blade portion may be provided on a side edge of the third fixed arm. The third fan blade portion may extend from the edge of the third fixed arm toward the inner rear wall of the outer tube 2.

[0120] In some embodiments, the axis of the first mounting hole near the third blade portion may be a fourth axis. A fourth axis center point may be provided on the fourth axis. The fourth axis center point may be the intersection of the fourth axis and the side wall of the flange near the third fixed arm. The vertical projection point of the fourth axis center point on the first reference plane 7 may be the third projection point. The line connecting the first axis center point b and the third projection point may be the third reference line. The third reference line may be provided on the first reference plane 7. A third reference point may be provided on the third blade portion. The third reference point may be the point on the third blade portion farthest from the first reference plane 7. The third reference point may be the point on the third blade portion closest to the rear wall of the outer cylinder 2. The intersection point of the third reference point perpendicular to the third reference line may be the third intersection point. The third intersection point may be the projection point of the third reference point on the third reference line. The angle formed between the line connecting the third reference point and the third intersection point and the first reference plane 7 may be γ.

[0121] It should be noted that, in some embodiments, the angle γ can be the same as the angle α. The angle γ can be the same as the angle β. The angle γ can be between 15 degrees and 75 degrees. Thus, when the inner tube 3 drives the third fan blade to rotate, it can ensure that the distance of the air flow driven by the third fan blade reaches the rear wall of the outer tube 2, and the airflow of the hot and humid air driven by the third fan blade can reach the rear wall of the outer tube 2 more quickly, thereby improving the condensation efficiency of the hot and humid air in the outer tube 2.

[0122] In some embodiments, in the length direction of the fan blade portion 63, the middle portion of the fan blade portion 63 can protrude in an arc shape toward the rear wall of the outer drum 2, and then when the inner drum 3 drives the fan blade portion 63 to rotate, the protruding portion of the fan blade portion 63 pushes the air toward the rear wall of the outer drum 2, so that a pressure difference is formed on both sides of the fan blade portion 63, thereby forming an airflow flowing toward the rear wall of the outer drum 2, so that the hot and humid air in the outer drum 2 can be quickly blown toward the rear wall of the outer drum 2, that is, the hot and humid air entering the outer drum 2 can be quickly blown toward the condensation plate 22, thereby improving the condensation efficiency of the hot and humid air in the outer drum 2, and thereby improving the drying efficiency of the clothes processing equipment.

[0123] It should be noted that, in some other embodiments, in the length direction of the fan blade portion 63 , both ends of the fan blade portion 63 may protrude and extend in an arc shape toward the rear wall of the outer cylinder 2 .

[0124] In some embodiments, the fan blade portion 63 can be provided at a side edge of the fixed arm 62. The fan blade portion 63 can be provided to extend obliquely from a side edge of the fixed arm 62 toward the rear wall of the outer tube 2. The fan blade portion 63 can be provided to extend obliquely from a side edge of the fixed arm 62 toward the adjacent boss 33. Multiple fan blade portions 63 can be provided to extend obliquely from a side edge of multiple fixed arms 62 toward the rear wall of the outer tube 2, so that when the fixed arm 62 drives the fan blade portion 63 to rotate, the airflow directions generated by the multiple fan blade portions 63 are the same, thereby improving the efficiency of the hot and humid air in the outer tube 2 flowing toward the rear wall of the outer tube 2. Multiple fan blade portions 63 can be provided at a side edge of multiple fixed arms 62, which can also improve the stability of the fan blade portion 63 during rotation.

[0125] It should be noted that in some other embodiments, fan blades 63 may be provided on opposite edges of the fixed arm 62 in the longitudinal direction. The fan blades 63 may extend obliquely from the opposite edges of the fixed arm 62 toward the rear wall of the outer cylinder 2. The fan blades 63 and the fixed arm 62 have the same inclination angle, so that when the fixed arm 62 drives the fan blades 63 to rotate, the airflow generated by the multiple fan blades 63 is in the same direction.

[0126] In some embodiments, the fan blade portion 63 and the fixed arm 62 can be provided in a one-to-one correspondence. One fixed arm 62 can be provided with a fan blade portion 63, so that when the fixed arm 62 drives the fan blade portion 63 to rotate, the rotation between the multiple fixed arms 62 can be more stable.

[0127] It should be noted that in some other embodiments, the number of fan blades 63 may be greater than the number of fixed arms 62. Multiple fan blades 63 may be provided on a single fixed arm 62. When the fixed arm 62 drives the multiple fan blades 63 to rotate, the multiple fan blades 63 can simultaneously generate airflow toward the rear wall of the outer drum 2, thereby rapidly blowing the hot and humid air entering the outer drum 2 toward the condensation tray 22, thereby improving the condensation efficiency of the hot and humid air in the outer drum 2 and, consequently, the drying efficiency of the clothes processing apparatus.

[0128] It should also be noted that, in some other embodiments, the number of blades 63 may be smaller than the number of fixed arms 62. The blades 63 may be provided on a portion of the fixed arm 62. When a portion of the fixed arm 62 rotates, driving its blades 63, the rotation of the blades 63 creates less resistance to the portion of the fixed arm 62, thereby reducing the driving force required to rotate the fixed arm 62 and, in turn, lowering the requirements for the motor.

[0129] While the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. Therefore, all changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
