Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and in particular to a fan assembly and clothing processing device for a clothing processing apparatus. Background Technology

[0002] In related technologies, the air duct components of clothing handling devices used for drying clothes often use unidirectional asynchronous external rotor motors due to limited space. This may be beneficial for timely heat dissipation of the motor and ensure normal operation of the system. However, the complex manufacturing process of this type of motor makes the air duct components equipped with this motor cost more. Summary of the Invention

[0003] Because the motor installation space in the duct housing is small, the heat dissipation of the motor is poor. Therefore, the prior art usually does not use an internal rotor motor for driving. The patent applicant discovered that there is usable space in the vertical direction of the duct housing. Therefore, the present invention proposes a fan assembly for a garment processing device. The fan assembly of the garment processing device has low cost and simple manufacturing process.

[0004] The present invention also proposes a garment processing device having a fan assembly of the above-mentioned garment processing device.

[0005] According to a first aspect of the present invention, a fan assembly of a garment handling apparatus includes: a duct housing having a mounting cavity; an impeller rotatably disposed within the mounting cavity; and a motor disposed in the duct housing, the motor including a stator and a rotor, the stator being sleeved on the outside of the rotor, the rotor being used to drive the impeller to rotate; the motor extending toward the upper cover of the garment handling apparatus and / or the inner wall of the duct housing, and the distance between the upper end of the motor and the upper cover of the garment handling apparatus being h1, h1 being greater than or equal to 5 mm, and the vertical distance between the lower end of the motor and the inner wall of the duct housing being h2, h2 being greater than or equal to 0.5 mm.

[0006] According to an embodiment of the present invention, the fan assembly of the garment processing device increases the vertical dimension of the motor by replacing the external rotor motor in related technologies with an internal rotor motor and setting the motor to extend towards the inner wall of the garment processing device's upper cover and / or air duct housing. This increase in motor size leads to a larger heat dissipation area, significantly improving the motor's heat dissipation efficiency. Furthermore, setting h1 to be greater than or equal to 5 mm and h2 to be greater than or equal to 0.5 mm ensures heat dissipation efficiency while preventing interference between the motor and other components, thus facilitating the normal operation of the fan assembly. Therefore, the fan assembly of the garment processing device of the present invention significantly reduces costs while ensuring the motor's heat dissipation efficiency, facilitates power output and connection to an external impeller, and simplifies the production process.

[0007] According to some embodiments of the present invention, the motor extends at least partially beyond the mounting cavity, the lower end of the motor extends downward beyond the lower outer surface of the mounting cavity by a distance h3, and the upper end of the motor extends upward beyond the upper outer surface of the mounting cavity by a distance h4, wherein h3 is greater than or equal to h4.

[0008] Since the fan assembly is mostly assembled to the drum assembly of the garment processing device, meaning the fan assembly moves with the drum assembly, an excessively large upward extension of the motor would greatly increase the possibility of interference with the top cover of the garment processing device. At the same time, since the relative movement (e.g., large vibration) between the motor and the air duct housing is relatively small, the present invention sets the motor to extend downward by a larger dimension, thereby reducing the possibility of interference between the motor and the top cover while ensuring the motor size.

[0009] In some embodiments, h3 is greater than or equal to 5 mm.

[0010] According to some embodiments of the present invention, h1 is greater than or equal to 10 mm.

[0011] According to some embodiments of the present invention, h2 is greater than or equal to 2 mm.

[0012] In some embodiments, the motor further includes a motor shaft connected to the rotor, the impeller being mounted on the motor shaft, wherein the lower end of the motor shaft extends downward beyond the mounting cavity, and the vertical distance between the lower end of the motor shaft and the inner wall of the duct housing is h2. Since the airflow is driven to move axially along the motor shaft, increasing the axial dimension of the motor has a relatively small impact on the airflow, thus enabling the use of an internal rotor motor and thereby reducing the cost of the fan assembly.

[0013] In some examples, the impeller is connected to the motor shaft via a connecting frame, the outer surface of which is formed as an arc-shaped transition zone, at least a portion of which is formed with an absolute value of the slope gradually increasing from bottom to top.

[0014] Because at least a portion of the arc-shaped transition zone is formed with an absolute value of the slope gradually increasing from bottom to top, the outer surface of the connecting frame protrudes outward, which is beneficial for the stator to extend downward in the axial direction, thereby improving the heat dissipation effect and effectively solving the heat dissipation problem.

[0015] According to some embodiments of the present invention, the duct housing has an upward-opening receiving recess adapted to at least partially extend into the mounting cavity, and the motor is located within the receiving recess.

[0016] In some embodiments, the duct housing includes: a first duct body, the mounting cavity being formed in the first duct body; a second duct body, the second duct body being connected to the first duct body through the mounting cavity, a cover plate being provided above the mounting cavity, at least a portion of the cover plate being recessed downward to form the receiving recess.

[0017] According to a second aspect of the present invention, a clothing processing apparatus includes a fan assembly of the clothing processing apparatus described in the above embodiments, the clothing processing apparatus having a drying function.

[0018] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The following is for reference. Figures 1-6 A fan assembly 100 of a garment processing apparatus according to an embodiment of the present invention is described.

[0036] like Figures 1-3 as well as Figure 5 As shown, the fan assembly 100 of the garment handling apparatus according to an embodiment of the present invention includes a duct housing 10, an impeller 21, and a motor 30. The duct housing 10 has a mounting cavity 101, the impeller 21 is rotatably disposed in the mounting cavity 101, and the motor 30 is disposed in the duct housing 10 for driving the impeller 21 to rotate, thereby generating airflow.

[0037] The motor 30 includes a stator 31 and a rotor 32, with the stator 31 sleeved on the outside of the rotor 32. That is, the motor 30 is an internal rotor motor; for example, it can be a single-phase asynchronous internal rotor motor. The rotor 32 can be directly connected to the impeller 21 or indirectly connected to it, thereby driving the impeller 21 to rotate.

[0038] Because the motor mounting space in the duct housing is small, the motor's heat dissipation is poor. Therefore, in the prior art, an internal rotor motor is generally not used to drive the impeller. However, the inventors of this application discovered that there is usable space in the vertical direction of the duct housing. Therefore, in this application, by setting the motor 30 to extend towards the upper cover 201 of the clothing handling device 200 and / or the inner wall of the duct housing 10, the vertical dimension of the motor 30 is increased. The increased size of the motor 30 increases its heat dissipation area, which can greatly improve the heat dissipation efficiency of the motor 30.

[0039] Furthermore, the vertical distance between the upper end of the motor 30 (i.e., the surface of the motor 30 at its highest point in the vertical direction) and the upper cover 201 of the clothing handling device 200 is h1, where h1 is greater than or equal to 5 mm. This not only prevents the motor 30 from colliding with the upper cover 201 of the clothing handling device 200 during operation, thus avoiding noise, but also facilitates airflow and heat dissipation of the motor 30. The vertical distance between the lower end of the motor 30 (i.e., the surface of the motor 30 at its lowest point in the vertical direction) and the inner wall of the air duct housing 10 is h2, where h2 is greater than or equal to 0.5 mm. This prevents the motor 30 from interfering with the inner wall of the air duct housing 10 during operation, thus ensuring heat dissipation efficiency while avoiding interference between the motor 30 and other components, which is beneficial for ensuring the normal operation of the fan assembly 100.

[0040] Therefore, the fan assembly 100 of the garment processing device according to the present invention, by replacing the external rotor motor in the related art with an internal rotor motor, can significantly reduce costs while ensuring the heat dissipation efficiency of the motor 30, facilitate power output and connection with the external impeller 21, and simplify the production process.

[0041] like Figure 2 As shown, in order to better reduce the possibility of the motor 30 colliding with the upper cover 201 of the clothing handling device 200 during operation and to ensure the heat dissipation effect of the motor 30, in some embodiments, the h1 is set to be greater than or equal to 10mm. For example, the h1 can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 20mm, etc.

[0042] like Figure 2 As shown, in order to better reduce the possibility of interference between the motor 30 and the inner wall of the air duct housing 10 during operation, and to ensure the heat dissipation effect of the motor 30, in some embodiments, h2 is set to be greater than or equal to 2mm. For example, h2 can be 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 3mm, etc.

[0043] Therefore, by limiting the distance between the upper end of the motor 30 and the upper cover 201 of the clothing handling device 200 and the vertical distance between the lower end of the motor 30 and the inner wall of the air duct housing 10, the purpose of facilitating airflow can be achieved, and the axial length of the stator 31 can be increased, which can significantly improve and optimize the heat dissipation effect of the motor 30.

[0044] like Figure 3 As shown, according to some embodiments of the present invention, the motor 30 extends at least partially beyond the mounting cavity 101. The lower end of the motor 30 (i.e., the lower surface of the motor 30) extends downward beyond the lower outer surface of the mounting cavity 101 by a distance h3, and the upper end of the motor 30 (i.e., the upper surface of the motor 30) extends upward beyond the upper outer surface of the mounting cavity 101 by a distance h4, where h3 is greater than or equal to h4. That is, the upper end of the motor 30 protrudes upward beyond the upper surface of the cover plate 113 described below, and the lower end of the motor 30 protrudes downward beyond the lower surface of the base 111 described below.

[0045] Since the fan assembly is mostly assembled to the drum assembly of the garment handling device, that is, the fan assembly moves with the drum assembly, an excessively large upward extension of the motor would greatly increase the possibility of interference with the top cover of the garment handling device. At the same time, since the relative movement (e.g., large vibration) between the motor and the air duct shell is small, the present invention sets the motor 30 to extend downward by a large dimension, thereby reducing the possibility of interference between the motor 30 and the top cover 201 of the garment handling device 200 while ensuring the size of the motor 30.

[0046] In some embodiments, h3 is greater than or equal to 5 mm. For example, h3 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.

[0047] like Figure 3 As shown, according to some embodiments of the present invention, the axial direction of the stator 31 of the motor 30 (e.g.) Figure 3 The length (shown in the vertical direction) is L1, which is 15-40mm. By increasing the axial dimension of the stator 31 inside the motor 30, the motor 30 can dissipate heat faster and more effectively.

[0048] In some embodiments, the axial length L1 of the stator 31 of the motor 30 is 15-30 mm. Specifically, L1 can be 15 mm, 20 mm, 25 mm, or 30 mm, etc.

[0049] like Figure 3 As shown, according to some embodiments of the present invention, the axial length of the motor 30 is L2, which is 50-100mm. By limiting the axial dimension of the motor 30, the heat dissipation problem of the internal rotor motor is improved and optimized.

[0050] In some embodiments, the axial length L2 of the motor 30 is 50-80 mm. Specifically, L2 can be 50 mm, 60 mm, 70 mm, or 80 mm, etc.

[0051] In some examples, the axial length L2 of the motor 30 is 86 mm, and the axial length L1 of the stator 31 of the motor 30 is 26 mm.

[0052] In some other examples, the axial length L2 of the motor 30 is 50 mm, and the axial length L1 of the stator 31 of the motor 30 is 15 mm.

[0053] In other examples, the axial length L2 of the motor 30 is 100 mm, and the axial length L1 of the stator 31 of the motor 30 is 40 mm.

[0054] like Figure 3 As shown, according to some embodiments of the present invention, the motor 30 further includes a motor shaft 33, which is connected to the rotor 32, and the impeller 21 is mounted on the motor shaft 33.

[0055] The lower end of the motor shaft 33 extends downward beyond the mounting cavity 101. The vertical distance between the lower end of the motor shaft 33 and the inner wall of the duct housing 10 is h2, which means that the vertical distance between the lower end of the motor shaft 33 and the inner wall of the duct housing 10 is greater than or equal to 0.5mm. This not only facilitates the connection between the motor shaft 33 and the impeller 21, thereby driving the impeller 21 to rotate through the motor shaft 33, but also reduces the possibility of interference between the motor 30 and the upper cover 201 while ensuring the size of the motor 30.

[0056] In some embodiments, the impeller 21 is connected to the motor shaft 33 via a connecting frame 22, and the outer surface of the connecting frame 22 is formed as an arc-shaped transition area, at least a portion of which is formed such that the absolute value of the slope gradually increases from bottom to top.

[0057] Therefore, by forming an arc-shaped transition area on the outer surface of the connecting frame 22, not only can the impeller 21 be installed at a position on the motor shaft 33 that extends downward beyond the mounting cavity 101 without affecting the installation of the impeller 21, but the axial dimension of the stator 31 can also be increased, thereby increasing the axial dimension of the motor 30 and ensuring the heat dissipation effect of the motor 30. Furthermore, it can increase the horizontal space of the fan assembly 100 to a certain extent, further improving the heat dissipation effect of the motor 30.

[0058] According to some embodiments of the present invention, the duct housing 10 has an upward-facing receiving recess 102, which is adapted to at least partially extend into the mounting cavity 101, and the motor 30 is located within the receiving recess 102. Specifically, the motor 30 can be fixed within the receiving recess 102 by fasteners such as screws. By forming the receiving recess 102 on the outer surface of the duct housing 10, it is not only convenient to position the motor 30, but also to reduce the space occupied by the motor 30 on the outside of the duct housing 10.

[0059] In some embodiments, the motor 30 further includes a motor shaft 33, which is connected to the rotor 32. The lower end of the motor shaft 33 passes through the bottom wall of the receiving recess 102 and is connected to the impeller 21, thereby driving the impeller 21 to rotate. The lower end of the motor shaft 33 can be directly connected to the impeller 21 or indirectly connected.

[0060] In some examples, the impeller 21 is connected to the motor shaft 33 via a connecting frame 22. The shape of the connecting frame 22 matches the shape of the receiving recess 102. For example, the outer surface of the connecting frame 22 is formed as an arc-shaped transition area, at least a portion of which is formed with an absolute value of the slope gradually increasing from bottom to top. A gap is left between the connecting frame 22 and the receiving recess 102 to avoid interference between them.

[0061] In some embodiments, the air duct housing 10 includes a first air duct body 11 and a second air duct body 12. A mounting cavity 101 is formed in the first air duct body 11. The second air duct body 12 is connected to the first air duct body 11 through the mounting cavity 101. A cover plate 113 is provided above the mounting cavity 101. At least a portion of the cover plate 113 is recessed downward to form a receiving recess 102.

[0062] Specifically, such as Figure 3 As shown, the first air duct body 11 includes a base 111, a cover 112, and a cover plate 113. The cover 112 and the cover plate 113 are respectively installed above different positions of the base 111. The base 111 and the cover 113 define the first air duct, and the base 111 and the cover plate 113 define the mounting cavity 101. The second air duct body 12 defines the second air duct, and the first air duct and the second air duct are connected through the mounting cavity 101.

[0063] In some examples, the upper end of the motor 30 protrudes from the upper outer surface of the duct housing 10 (i.e., the upper surface of the cover plate 113), and the lower end of the motor 30 protrudes from the lower surface of the impeller 21.

[0064] In other examples, the upper end of the motor 30 does not protrude from the upper outer surface of the duct housing 10 (i.e., the upper surface of the cover plate 113), and the lower end of the motor 30 protrudes from the lower surface of the impeller 21.

[0065] In some other examples, the upper end of the motor 30 protrudes from the upper outer surface of the duct housing 10 (i.e., the upper surface of the cover plate 113), and the lower end of the motor 30 does not protrude from the lower surface of the impeller 21.

[0066] In some other examples, the upper end of the motor 30 does not protrude from the upper outer surface of the duct housing 10 (i.e., the upper surface of the cover plate 113), and the lower end of the motor 30 does not protrude from the lower surface of the impeller 21.

[0067] To ensure a tight seal between the base 111 and the cover plate 113, a first sealing element 371 is provided between them. To ensure a tight seal between the first air duct body 11 and the second air duct body 12, a second sealing element 372 is provided between them, i.e., between the base 111 and the second air duct body 12. The first air duct body 11 can be made of metal, and the second air duct body 12 can be made of plastic.

[0068] The following is combined with Figures 1-6 A specific embodiment of the fan assembly 100 of the garment handling apparatus according to the present invention will be described in detail.

[0069] like Figures 1-4 As shown, the fan assembly 100 of the garment handling device includes a duct housing 10, an impeller 21, and a motor 30.

[0070] The air duct shell 10 includes a first air duct body 11 and a second air duct body 12.

[0071] The first air duct body 11 includes a base 111, a cover 112, and a cover plate 113. The cover 112 and the cover plate 113 are respectively positioned above the base 111 at different locations. The base 111 and the cover 113 define the first air duct and the mounting cavity 101. The upper part of the base 111 has a first mounting groove, within which a first sealing element 371 is provided. The cover plate 113 has a protrusion pressing against the first sealing element 371, thereby sealingly connecting the cover plate 113 to the upper part of the base 111. The middle part of the cover plate 113 is recessed downwards, forming a receiving recess 102 with an upper opening on the outer surface of the middle part of the cover plate 113. The bottom wall of the receiving recess 102 has a through hole.

[0072] The second air duct body 12 is located below the base 111, defining a second air duct. The lower part of the base 111 has a second mounting groove, within which a second sealing element 372 is provided. The second air duct body 12 has a flange pressed against the second sealing element 372, thereby sealingly connecting the second air duct body 12 to the lower part of the base 111. The first and second air ducts are connected via the mounting cavity 101.

[0073] The motor 30 is disposed in the receiving recess 102. The motor 30 includes a stator 31, a rotor 32, a motor shaft 33, a motor housing 34, a motor cover 35, and bearings 36. The motor cover 35 is disposed on the top of the motor housing 34, defining a receiving cavity between the motor cover 35 and the motor housing 34. Bearings 36 are respectively provided at opposite positions on the motor housing 34 and the motor cover 35. The two ends of the motor shaft 33 are rotatably supported on the bearings 36 at corresponding positions. The stator 31 and the rotor 32 are both disposed in the receiving cavity. The stator 31 is sleeved on the outside of the rotor 32, and the rotor 32 is sleeved on the outside of the motor shaft 33 and connected to the motor shaft 33, thereby driving the motor shaft 33 to rotate together. The motor shaft 33 extends in the vertical direction, and the lower end of the motor shaft 33 passes through a through hole, thus extending downward beyond the mounting cavity 101.

[0074] The impeller 21 is mounted on the lower end of the motor shaft 33 via the connecting bracket 22. The lower end of the motor shaft 33 is also provided with a limiting member 23, which serves to limit the movement and prevent the connecting bracket 22 from coming off the lower end of the motor shaft 33.

[0075] like Figure 3 and Figure 5 As shown, the vertical distance between the upper end of the motor 30 and the upper cover 201 of the clothing handling device 200 is h1, where h1 is greater than or equal to 5 mm. The vertical distance between the lower end of the motor 30 (i.e., the lower end of the motor shaft 33) and the inner wall of the air duct housing 10 is h2, where h2 is greater than or equal to 0.5 mm. The lower end of the motor 30 extends downward beyond the lower surface of the base 111, and the distance between the lower end of the motor 30 and the lower surface of the base 111 is h3, where h3 is greater than or equal to 5 mm. The upper end of the motor 30 extends upward beyond the upper surface of the cover plate 113, and the distance between the upper end of the motor 30 and the upper surface of the cover plate 113 is h4, where h4 is less than or equal to h3. The axial length of the stator 31 of the motor 30 is L1, where L1 is 15-40 mm. The axial length of the motor 30 is L2, where L2 is 50-100 mm.

[0076] It should be noted that the motor 30 in this application is an internal rotor motor. Under the same power conditions, the axial length of the motor in this application is less than the axial length of the external rotor motor in the related art.

[0077] like Figure 4 and Figure 5 As shown, the clothing processing device 200 according to an embodiment of the present invention includes the fan assembly 100 of the clothing processing device of the above embodiment. The clothing processing device has a drying function. For example, the clothing processing device can be a dryer or a washer-dryer combo.

[0078] Specifically, the garment handling device 200 includes a housing, a tub assembly, and a fan assembly 100. The tub assembly is located inside the housing, the fan assembly 100 is located on top of the tub assembly, and the fan assembly 100 is located between the tub assembly and the upper cover 201 of the housing.

[0079] Since the fan assembly 100 of the clothing processing device according to the embodiment of the present invention has the above-mentioned technical effects, the clothing processing device 200 according to the embodiment of the present invention also has the above-mentioned technical effects, that is, the clothing processing device 200 of the embodiment of the present invention has low cost, simple manufacturing process, and good heat dissipation effect.
