[0065] Figure 3 is Figure 2 is a structural schematic view from another perspective. Figure 4 is Figure 3 is a partial enlarged structural schematic view.

[0066] as Figure 3and Figure 4 As shown, in some embodiments, a drive device may be provided within the housing 1. The drive device may be provided outside the outer drum 21. The drive device may also be provided within the housing 1. The drive device may be in transmission connection with the inner drum 22. The drive device can drive the inner drum 22 to rotate relative to the outer drum 21, thereby achieving the washing or dehydration function of the laundry processing chamber 20 in the inner drum 22.

[0067] In some embodiments, a drive shaft 24 may be provided at the axis of the barrel assembly 2. The drive shaft 24 may be rotatably connected to the axis of the outer barrel 21. The drive shaft 24 may be coaxially connected to the axis of the inner barrel 22. A drive device may be connected to the drive shaft 24. Thus, the drive device can drive the drive shaft 24 to rotate, thereby driving the inner barrel 22 to rotate within the outer barrel 21 via the drive shaft 24.

[0068] like Figure 3 and Figure 4 As shown, in some embodiments, the drive device may include a drive motor 3. The drive motor 3 may be disposed within the housing 1. The drive motor 3 may be disposed outside the outer cylinder 21. The output shaft 31 of the drive motor 3 may be in driving connection with the transmission shaft 24. Thus, when the drive motor 3 is in operation, the output shaft 31 of the drive motor 3 may drive the transmission shaft 24 to rotate, thereby driving the inner cylinder 22 to rotate within the outer cylinder 21 via the transmission shaft 24.

[0069] In some embodiments, the drive device may include a drive wheel 4. A transmission wheel 25 may be provided on a transmission shaft 24. The drive wheel 4 and the transmission wheel 25 may be connected by a transmission belt (not shown). Thus, when the drive motor 3 is in operation, the output shaft 31 of the drive motor 3 can drive the drive wheel 4 to rotate coaxially, so that the drive wheel 4 drives the transmission wheel 25 to rotate synchronously via the transmission belt. The transmission wheel 25 can then drive the transmission shaft 24 to rotate coaxially, thereby driving the inner cylinder 22 to rotate within the outer cylinder 21 via the transmission shaft 24.

[0070] In some embodiments, a reducer (not shown) may be provided inside the outer cylinder 21. The transmission shaft 24 may be connected to the axis of the inner cylinder 22 via the reducer.

[0071] like Figure 3 and Figure 4 As shown, in some embodiments, a mounting seat 27 may be provided at the bottom of the outer cylinder 21. The drive motor 3 may be fixed on the mounting seat 27. It should be noted that, in other embodiments, the drive motor 3 may also be directly fixed on the outer wall of the outer cylinder 21.

[0072] Figure 5 yes Figure 4A structural schematic diagram of the driving motor 3, the driving wheel 4 and the heat dissipation wheel 5.

[0073] As shown in Figure 4 and Figure 5 , in some embodiments, the driving device can include a heat dissipation wheel 5. The heat dissipation wheel 5 can be provided on the output shaft 31 of the driving motor 3. The heat dissipation wheel 5 can be provided at one end of the driving motor 3 in the axial direction. The heat dissipation wheel 5 can be arranged in a spaced manner with the driving motor 3. When the driving motor 3 is working, the output shaft 31 of the driving motor 3 can drive the heat dissipation wheel 5 to rotate synchronously, and the heat dissipation wheel 5 can blow air towards the driving motor 3 for heat dissipation.

[0074] In some embodiments, the output shaft 31 of the driving motor 3 can be located on the axis of the driving motor 3. The output shaft 31 of the driving motor 3 can be located at one end of the driving motor 3 in the axial direction. In this way, by providing the heat dissipation wheel 5 on the output shaft 31 of the driving motor 3, the heat dissipation wheel 5 can be provided at one end of the driving motor 3 in the axial direction. When the heat dissipation wheel 5 rotates with the output shaft 31 of the driving motor 3, the heat dissipation wheel 5 can blow air towards the driving motor 3 from one end of the driving motor 3 in the axial direction for heat dissipation.

[0075] Figure 6 is Figure 5 a schematic diagram of the exploded view.

[0076] As shown in Figure 5 and Figure 6 , in some embodiments, a first heat dissipation hole 32 can be provided on the end face of the driving motor 3 in the axial direction. In this way, when the heat dissipation wheel 5 rotates with the output shaft 31 of the driving motor 3, the heat dissipation wheel 5 can blow air towards the first heat dissipation hole 32, and then blow air towards the inside of the driving motor 3 for heat dissipation.

[0077] In some embodiments, the first heat dissipation hole 32 can be provided in two groups. One group of the first heat dissipation hole 32 can be provided on the end face of the driving motor 3 facing the heat dissipation wheel 5, and multiple first heat dissipation holes 32 in this group of the first heat dissipation hole 32 can be arranged in a circumferential spaced manner around the output shaft 31 of the driving motor 3. Another group of the first heat dissipation hole 32 can be provided on the end face of the driving motor 3 away from the heat dissipation wheel 5, and multiple first heat dissipation holes 32 in this group of the first heat dissipation hole 32 can also be arranged in a circumferential spaced manner around the output shaft 31 of the driving motor 3. In this way, when the heat dissipation wheel 5 blows air towards one group of the first heat dissipation hole 32, the air inside the driving motor 3 can be blown out through another group of the first heat dissipation hole 32, so as to realize the blowing heat dissipation inside the driving motor 3.

[0078] As shown in Figure 5 and Figure 6As shown, in some embodiments, the outer peripheral wall of the drive motor 3 may be provided with a second heat dissipation hole 33. The second heat dissipation hole 33 may be provided on the outer peripheral wall of the drive motor 3 at one end near the heat dissipation wheel 5. In this way, when the heat dissipation wheel 5 rotates with the output shaft 31 of the drive motor 3, the heat dissipation wheel 5 can blow air toward the second heat dissipation hole 33, thereby blowing air into the interior of the drive motor 3 to dissipate heat.

[0079] In some embodiments, multiple second heat dissipation holes 33 may be provided. The multiple second heat dissipation holes 33 may be circumferentially spaced around the outer peripheral wall of the drive motor 3. The multiple second heat dissipation holes 33 may be circumferentially spaced around the output shaft 31 of the drive motor 3. In this way, when the heat dissipation wheel 5 rotates with the output shaft 31 of the drive motor 3, the heat dissipation wheel 5 can simultaneously blow air toward the multiple second heat dissipation holes 33, thereby improving the heat dissipation efficiency within the drive motor 3.

[0080] In some embodiments, two groups of second heat dissipation holes 33 may be provided. The plurality of second heat dissipation holes 33 in one group may be located on the outer peripheral wall of the drive motor 3 at the end closest to the heat dissipation wheel 5. The plurality of second heat dissipation holes 33 in this group may be circumferentially spaced around the output shaft 31 of the drive motor 3. The plurality of second heat dissipation holes 33 in the other group may be located on the outer peripheral wall of the drive motor 3 at the end farther from the heat dissipation wheel 5. The plurality of second heat dissipation holes 33 in this group may also be circumferentially spaced around the output shaft 31 of the drive motor 3. In this manner, when the heat dissipation wheel 5 rotates with the output shaft 31 of the drive motor 3, the heat dissipation wheel 5 can blow air toward the plurality of second heat dissipation holes 33 in the one group, dissipating heat within the drive motor 3. Furthermore, the air within the drive motor 3 can be discharged through the plurality of second heat dissipation holes 33 in the other group, dissipating heat within the drive motor 3.

[0081] It should be noted that, in some other embodiments, only one group of first heat dissipation holes 32 may be provided. Alternatively, only one group of second heat dissipation holes 33 may be provided.

[0083] like Figure 6 、 Figure 7 and Figure 8 As shown, in some embodiments, the drive wheel 4 and the axial end surface of the drive motor 3 can be spaced apart. The heat dissipation wheel 5 can be provided on the side of the drive wheel 4 close to the drive motor 3. In this way, when the output shaft 31 of the drive motor 3 drives the drive wheel 4 to rotate, the drive wheel 4 can drive the heat dissipation wheel 5 to rotate, thereby blowing air toward the drive motor 3 to dissipate heat.

[0084] In some embodiments, the heat dissipation wheel 5 can be injection molded on the side of the driving wheel 4 close to the driving motor 3. In this way, the heat dissipation wheel 5 can be embedded in the driving wheel 4 close to the driving motor 3 by injection molding, so that the heat dissipation wheel 5 and the driving wheel 4 are connected as a whole, and the driving wheel 4 can stably drive the heat dissipation wheel 5 to rotate synchronously. This way, the heat dissipation wheel 5 and the driving wheel 4 do not need to be assembled, but can be injection molded by an injection molding machine and a mold, which is beneficial to reduce the cost.

[0085] In some embodiments, the side of the driving wheel 4 close to the driving motor 3 can be provided with a connecting wall 41. The connecting wall 41 can be annular, and the connecting wall 41 can extend towards the side close to the driving motor 3. During the injection molding of the heat dissipation wheel 5, the driving wheel 4 can be used as an insert to embed the connecting wall 41 in the heat dissipation wheel 5, so that the heat dissipation wheel 5 and the connecting wall 41 are connected as a whole. In this way, the driving wheel 4 can be connected to the heat dissipation wheel 5 through the connecting wall 41, so that when the driving wheel 4 rotates, the driving wheel 4 can stably drive the heat dissipation wheel 5 to rotate synchronously through the annular connecting wall 41.

[0086] As shown in Figure 7 and Figure 8 In some embodiments, during the injection molding of the heat dissipation wheel 5, the side of the heat dissipation wheel 5 away from the driving motor 3 can be formed with an embedding groove 511. The embedding groove 511 can be provided on the side of the heat dissipation wheel 5 facing the driving wheel 4. The connecting wall 41 can be embedded in the embedding groove 511, and then connected to the heat dissipation wheel 5 as a whole.

[0087] In some embodiments, the outer circumferential wall of the connecting wall 41 can be provided with a connecting rib 411. The connecting rib 411 can be arranged in an arc shape on the outer circumferential wall of the connecting wall 41. The connecting rib 411 can be provided with a plurality of connecting ribs 411 arranged circumferentially on the outer circumferential wall of the connecting wall 41. When the heat dissipation wheel 5 is injection molded, the connecting rib 411 can be embedded in the heat dissipation wheel 5 together with the connecting wall 41, so that the heat dissipation wheel 5, the connecting wall 41 and the connecting rib 411 are connected as a whole. In this way, after the heat dissipation wheel 5 is injection molded, the plurality of connecting ribs 411 can firmly connect the connecting wall 41 in the heat dissipation wheel 5, improving the connection strength and stability of the heat dissipation wheel 5 and the driving wheel 4.

[0088] It should be noted that in other embodiments, the connecting rib 411 can also be provided in other shapes on the outer circumferential wall of the connecting wall 41.

[0089] In other embodiments, the heat dissipation wheel 5 and the driving wheel 4 can also be detachably connected as a whole.

[0090] As shown in Figure 7 and Figure 8As shown, in some embodiments, a fixing sleeve 42 is protruding from the side of the drive wheel 4 away from the heat dissipation wheel 5. When the drive wheel 4 is mounted on the output shaft 31 of the drive motor 3, the output shaft 31 of the drive motor 3 can be inserted into the fixing sleeve 42. The outer wall of the fixing sleeve 42 can be provided with a fixing member 43, which can be a screw. The fixing member 43 can be inserted into the fixing sleeve 42 and abut against the output shaft 31 of the drive motor 3, thereby fixing the drive wheel 4 to the output shaft 31 of the drive motor 3.

[0092] like Figure 6 、 Figure 9 and Figure 10 As shown, in some embodiments, the heat dissipation wheel 5 may include a wheel body 51. The wheel body 51 may be sleeved on the outer circumference of the output shaft 31 of the drive motor 3. The wheel body 51 may be annular, and the wheel body 51 may be circumferentially arranged around the outer circumference of the output shaft 31 of the drive motor 3. The wheel body 51 may be provided on a side of the drive wheel 4 close to the drive motor 3. One end of the drive wheel 4 close to the drive motor 3 may be embedded in the wheel body 51, so that the drive wheel 4 and the wheel body 51 are connected as a whole. In this way, when the output shaft 31 of the drive motor 3 drives the drive wheel 4 to rotate, the drive wheel 4 can drive the wheel body 51 to rotate synchronously.

[0093] In some embodiments, during the injection molding process of the heat dissipation wheel 5 , the driving wheel 4 can be used as an insert, so that the connecting wall 41 is embedded in the wheel body 51 , so that the wheel body 51 and the connecting wall 41 are connected as one body.

[0094] It should be noted that, in some other embodiments, the wheel body 51 may also be detachably snap-connected to the side of the drive wheel 4 close to the drive motor 3. In this way, by detachably snapping the wheel body 51 to the side of the drive wheel 4 close to the drive motor 3, the heat dissipation wheel 5 can be assembled by snap-fitting instead of by integral injection molding.

[0095] In some embodiments, when the heat dissipating wheel 5 is injection molded, the engaging groove 511 can be provided on the side of the wheel body 51 facing the driving wheel 4. The connecting wall 41 can be embedded in the engaging groove 511 and then connected to the wheel body 51 as a whole.

[0096] In some embodiments, the heat dissipation wheel 5 can include heat dissipation blades 52. The heat dissipation blades 52 can be provided in plurality, and the plurality of heat dissipation blades 52 are arranged circumferentially at intervals on the side of the wheel body 51 facing the driving motor 3. In this way, when the driving wheel 4 drives the wheel body 51 to rotate, the wheel body 51 can drive the plurality of heat dissipation blades 52 to rotate synchronously, and the plurality of heat dissipation blades 52 can drive the surrounding air to blow towards the driving motor 3, thereby achieving air blowing heat dissipation of the driving motor 3. In addition, the number of heat dissipation blades 52 can be adjusted as needed, which is not limited herein.

[0097] Figure 11 is Figure 10 a sectional view in A-A direction.

[0098] As Figure 5 and Figure 11 shown, in some embodiments, the heat dissipation blades 52 can include an integral radial blade arm 521 and an axial blade arm 522. The inner end of the radial blade arm 521 can be directed towards the center of the wheel body 51. The outer end of the radial blade arm 521 can be arranged extending towards the outer circumferential direction of the wheel body 51. The axial blade arm 522 is arranged extending towards the side close to the driving motor 3 from the outer end of the radial blade arm 521. The radial blade arm 521 can be arranged at intervals with the axial end face of the driving motor 3. The axial blade arm 522 can be arranged at intervals with the outer circumferential wall of the driving motor 3. When the wheel body 51 drives the plurality of heat dissipation blades 52 to rotate synchronously, the plurality of radial blade arms 521 rotate synchronously, and the plurality of radial blade arms 521 can disturb the surrounding air to blow towards the corresponding axial end face of the driving motor 3 for air blowing heat dissipation. At the same time, the plurality of axial blade arms 522 rotate synchronously, and the plurality of axial blade arms 522 can disturb the surrounding air to blow towards the outer circumferential wall of the driving motor 3 for air blowing heat dissipation.

[0099] In some embodiments, the radial blade arm 521 can be arranged in the radial direction of the wheel body 51. When the radial blade arm 521 rotates with the wheel body 51, by arranging the radial blade arm 521 in the radial direction of the wheel body 51, the arrangement direction of the radial blade arm 521 can be perpendicular to its rotation direction, thereby enabling the radial blade arm 521 to push as much air as possible to flow in its rotation direction, and enabling the flowing air to blow towards the corresponding end face of the driving motor 3 for air blowing heat dissipation.

[0100] In some embodiments, the axial blade arm 522 is extended and arranged along the axial direction of the wheel body 51. One end of the axial blade arm 522 can be connected to the side wall of the wheel body 51. The axial direction of the wheel body 51 is the axial direction of the output shaft 31 of the drive motor 3. When the axial blade arm 522 rotates with the wheel body 51, the axial blade arm 522 is extended and arranged along the axial direction of the wheel body 51, so that the axial blade arm 522 can be arranged along the axial direction of the output shaft 31 of the drive motor 3, and the arrangement direction of the axial blade arm 522 can be perpendicular to its rotation direction, so that the axial blade arm 522 can push as much air as possible to flow along its rotation direction, so that the flowing air is blown toward the outer peripheral wall of the drive motor 3 for heat dissipation.

[0101] In some embodiments, when the multiple radial blade arms 521 rotate, the wind generated by the multiple radial blade arms 521 can be blown into the interior of the drive motor 3 through the first heat dissipation hole 32 on the end face of the drive motor 3, thereby achieving air blowing and heat dissipation inside the drive motor 3 and improving the heat dissipation effect of the drive motor 3.

[0102] like Figure 5 and Figure 11 As shown, in some embodiments, in the direction from the inner end of the radial blade arm 521 toward the outer end thereof, the radial blade arm 521 can be arranged obliquely toward the side close to the drive motor 3. The radial blade arms 521 of a plurality of heat dissipation blades 52 can be combined to form a blade structure that gathers wind toward the center of the drive motor 3. In this way, when the plurality of radial blade arms 521 rotate synchronously, the inclined arrangement structure of the radial blade arms 521 allows the plurality of radial blade arms 521 to gather the surrounding air toward the center of the corresponding end face of the drive motor 3, so that the wind can be smoothly blown into the interior of the drive motor 3 through the first heat dissipation hole 32, thereby ensuring the air intake on the end face and preventing the wind from diverging, which is beneficial for the heat dissipation wheel 5 to improve the heat dissipation effect on the drive motor 3.

[0103] In some embodiments, the radial blade arm 521 has an edge that is inclined toward the drive motor 3 along the direction from the inner end of the radial blade arm 521 toward its outer end. A straight line along the inclined direction of this edge is a first reference line L1, and the angle α between the first reference line L1 and the axial direction of the drive motor 3 can satisfy the following condition: α≤87°. Thus, by ensuring that α≤87°, the radial blade arm 521 has a sufficient inclination, ensuring that the radial blade arm 521 can gather surrounding air toward the center of the corresponding end face of the drive motor 3, preventing wind from dispersing and improving the heat dissipation effect of the heat dissipation wheel 5 on the drive motor 3.

[0104] In some embodiments, the angle α between the first reference line L1 and the axis of the drive motor 3 can satisfy the following requirement: α ≥ 80°. Thus, by ensuring that α ≥ 80°, the radial blade arms 521 will not tilt excessively, thereby ensuring that the air disturbed by the radial blade arms 521 is blown toward the corresponding end face of the drive motor 3 as much as possible, thereby ensuring the air intake on the end face and improving the heat dissipation effect of the heat dissipation wheel 5 on the drive motor 3.

[0105] In some embodiments, the angle α between the first reference line L1 and the axis direction of the drive motor 3 can satisfy the following: 80°≤α≤87°. Thus, by setting the angle 80°≤α≤87°, the radial blade arm 521 can meet the inclination requirement and prevent the radial blade arm 521 from being excessively tilted. This allows the air disturbed by the radial blade arm 521 to be blown toward the corresponding end face of the drive motor 3 as much as possible and to converge toward the center of the corresponding end face of the drive motor 3, thereby preventing wind force from diverging and ensuring the air intake on the end face, thereby improving the heat dissipation effect of the heat dissipation wheel 5 on the drive motor 3.

[0106] In some embodiments, the angle α between the first reference line L1 and the axis of the drive motor 3 can satisfy the following: α = 85°. Thus, by setting α = 85°, the radial blade arms 521 can have a relatively good inclination angle, which can prevent wind force from diverging while ensuring the air intake on the end face, thereby meeting the heat dissipation requirements of the heat dissipation wheel 5 for the drive motor 3.

[0107] like Figure 5 and Figure 11 As shown, in some embodiments, in the radially outward direction of the wheel body 51, the wheel body 51 is tilted toward the side close to the drive motor 3. The straight line along the tilt direction of the wheel body 51 is the second reference line L2, and the angle β between the second reference line L2 and the axial direction of the wheel body 51 can satisfy: β≤88°. In this way, by β≤88°, the wheel body 51 can have a sufficient tilt angle in its radially outward direction, thereby ensuring that the radial blade arm 521 has a sufficient tilt angle, ensuring that when the radial blade arm 521 rotates, the surrounding air can be gathered toward the center of the corresponding end face of the drive motor 3, preventing wind force from diverging, and improving the heat dissipation effect of the heat dissipation wheel 5 on the drive motor 3.

[0108] In some embodiments, the angle β between the second reference line L2 and the axis of the wheel body 51 satisfies: β ≥ 85°. Thus, by ensuring that β ≥ 85°, the wheel body 51 is prevented from excessively tilting in its radially outward direction, thereby preventing excessive tilting of the radial blade arms 521. This ensures that the air disturbed by the radial blade arms 521 is blown toward the corresponding end face of the drive motor 3 as much as possible, thereby ensuring the air intake on the end face and improving the heat dissipation effect of the heat dissipation wheel 5 on the drive motor 3.

[0109] In some embodiments, the angle β between the second reference line L2 and the axial direction of the wheel body 51 satisfies: 85°≤β≤88°. In this way, by 85°≤β≤88°, the requirements of the wheel body 51 and the radial blade arm 521 on the inclination can be met, and the wheel body 51 and the radial blade arm 521 will not be excessively inclined, so that the air disturbed by the wheel body 51 and the radial blade arm 521 can be blown to the corresponding end face of the driving motor 3 as much as possible, gathered towards the center of the corresponding end face of the driving motor 3, prevent the wind from dissipating, ensure the air intake on the end face, and thus improve the heat dissipation effect of the heat dissipation wheel 5 on the driving motor 3.

[0110] In some embodiments, the angle β between the second reference line L2 and the axial direction of the wheel body 51 satisfies: β=87°. In this way, by β=87°, the wheel body 51 and the radial blade arm 521 can have a good inclination angle, which can prevent the wind from dissipating and ensure the air intake on the end face, so as to meet the heat dissipation requirements of the heat dissipation wheel 5 on the driving motor 3.

[0111] As shown in Figure 5 and Figure 11 In some embodiments, when the plurality of axial blade arms 522 rotate, the wind generated by the plurality of axial blade arms 522 can be blown into the driving motor 3 through the second heat dissipation holes 33 on the outer peripheral wall of the driving motor 3, so as to realize the air blowing heat dissipation inside the driving motor 3 and improve the heat dissipation effect of the heat dissipation wheel 5 on the driving motor 3.

[0112] In some embodiments, the end of the axial blade arm 522 away from the radial blade arm 521 can extend to the outside of the second heat dissipation hole 33. In this way, when the axial blade arm 522 rotates, the wind generated by the axial blade arm 522 can smoothly blow into the driving motor 3 through the second heat dissipation hole 33, so as to improve the heat dissipation effect inside the driving motor 3.

[0113] As shown in Figure 5 In some embodiments, when the axial blade arm 522 rotates, the axial blade arm 522 can cover the outside of part of the second heat dissipation hole 33. It should be noted that in other embodiments, when the axial blade arm 522 rotates, the axial blade arm 522 can cover the outside of the entire second heat dissipation hole 33.
