[0043] The embodiments of this utility model 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 this utility model, and should not be construed as limiting this utility model.

[0044] Existing garment processing equipment typically includes a drying function. During operation, airflow enters from the base, flows through the heat exchange components, and is then guided by the fan assembly into the inner drum of the garment processing equipment for drying. For garment processing equipment, the placement of the fan assembly and the construction of the air duct both affect airflow, thus impacting the drying efficiency. In related technologies, after passing through the heat exchange components, the airflow flows through a curved duct in the base, through the fan assembly and the rear cover, before entering the inner drum of the garment processing equipment. This results in high wind resistance and noise, low airflow volume, and a poor user experience.

[0045] The following is for reference. Figures 1-10 This invention describes a garment processing device according to an embodiment of the present invention.

[0046] The garment processing device 1 according to this utility model includes a cylindrical body 11, a base 121, a fan assembly 122, a rear cover assembly 14, and an air guide 13. A garment processing chamber 111 is formed inside the cylindrical body 11. The base 121 is disposed at the bottom of the cylindrical body 11 and has an air duct 1211 that communicates with the garment processing chamber 111. The fan assembly 122 is housed in the air duct 1211 and has an air outlet 1223. The fan assembly 122 is adapted to discharge the airflow in the air duct 1211. The rear cover assembly 14 is disposed in the cylindrical body 11 and has an air supply channel 15. One end of the air supply channel 15 communicates with the air outlet 1223, and the other end of the air supply channel 15 communicates with the garment processing chamber 111. The air guide 13 is disposed in the rear cover assembly 14. At least a portion of the air guide 13 is located in the air supply channel 15 and is used to guide the airflow discharged from the air outlet 1223 to the garment processing chamber 111.

[0047] The garment processing device 1 includes a cylindrical body 11, within which a garment processing chamber 111 for accommodating garments is formed. A base 121 is located at the bottom of the cylindrical body 11, supporting the cylindrical body 11 and improving the overall structural stability of the garment processing device 1. An air duct 1211 communicating with the garment processing chamber 111 is formed within the base 121. A fan assembly 122 is arranged within the air duct 1211, with its inlet connected to the air duct 1211. Airflow can enter the fan assembly 122 along the air duct 1211 and exit under the guidance of the fan assembly 122. A rear cover assembly 14 is located at the rear of the cylindrical body 11, with its bottom connected to the base 121. Thus, the cylindrical body 11 and the rear cover assembly 14 are respectively located on top of the base 121 and spaced apart in the front-to-back direction. This arrangement of the cylindrical body 11, base 121, and rear cover assembly 14 makes the overall structure of the garment processing device 1 more compact and space-saving.

[0048] A heat exchange component 123 can be installed inside the air duct 1211. The humid air entering the air duct 1211 is converted into hot air after heat exchange by the heat exchange component 123 and enters the clothes processing chamber 111 for drying clothes.

[0049] The rear cover assembly 14 is provided with an air supply channel 15 that communicates with the clothes processing chamber 111. The air outlet 1223 in the fan assembly 122 is connected to the air supply channel 15. After passing through the fan assembly 122, the airflow can enter the air supply channel 15 and then enter the clothes processing chamber 111 to dry the clothes. The design of the air supply channel 15 forms a direct and efficient connection between the air outlet 1223 of the fan assembly 122 and the clothes processing chamber 111, ensuring that the airflow can be smoothly delivered into the clothes processing chamber 111. The airflow after drying the clothes forms humid gas. The humid gas can return to the base 121 and, after passing through the heat exchange component 123 (e.g., evaporator), regenerate high-temperature gas and enter the clothes processing chamber 111 through the fan assembly 122 for recycling, thereby improving the clothes drying effect of the clothes processing equipment 1.

[0050] The fan assembly 122 is housed in the air duct 1211 of the base 121 and is located behind the heat exchange component 123. This arrangement allows the high-temperature airflow formed after the airflow passes through the heat exchange component 123 to directly enter the fan assembly 122, reducing additional wind resistance and energy loss.

[0051] An air guide 13 is also provided in the air supply channel 15 formed by the rear cover assembly 14. The air guide 13 extends along the air supply channel 15 and can improve the airflow distribution in the air supply channel 15. Through the guiding effect of the air guide 13, the airflow entering the air supply channel 15 can flow into the garment processing chamber 111 more evenly. Moreover, the airflow is guided by the air guide 13 when entering the air supply channel 15, resulting in low noise and a good user experience.

[0052] According to one embodiment of the present invention, the fan assembly 122 is provided with multiple air outlets 1223, and the air guide 13 divides the air supply channel 15 into multiple sub-air channels 150, each sub-air channel 150 communicating with at least one air outlet 1223. The air guide 13 defines multiple sub-air channels 150 within the air supply channel 15, each of which allows airflow to pass through, making the airflow entering the air supply channel 15 more uniform and reducing dead zones and eddies in the airflow within the air supply channel 15. Each sub-air channel 150 is responsible for guiding the airflow to different areas of the garment processing chamber 111, ensuring a more uniform distribution of airflow within the garment processing chamber 111. A more uniform airflow distribution means that the garments can be heated more evenly, and all parts of the garments can be properly treated, avoiding localized dampness caused by uneven airflow distribution. This improves airflow utilization efficiency and the drying effect of the garment processing equipment 1. The fan assembly 122 is provided with multiple air outlets 1223. The multiple air outlets 1223 increase the air volume of the fan assembly 122. Each air outlet 1223 corresponds to a sub-duct 150, which allows the airflow from the air outlet 1223 to directly enter the corresponding sub-duct 150, reducing wind resistance and wind noise.

[0053] According to one embodiment of the present invention, at least one sub-air duct 150 has a gradually increasing cross-sectional area in the direction away from the base 121. As the cross-sectional area of ​​the sub-air duct 150 gradually increases, the airflow speed as it passes through the sub-air duct 150 gradually decreases, which can reduce the airflow resistance in the sub-air duct 150 and make the airflow flow more smoothly towards the garment processing chamber 111. When the airflow passes through the gradually increasing sub-air duct 150, the airflow state is more stable, reducing the noise generated by the airflow and improving the user experience.

[0054] According to one embodiment of the present invention, the rear cover assembly 14 includes a rear cover 141 and a rear plate 142. The rear cover 141 has a cavity that opens toward the cylinder 11, and an air guide 13 is disposed in the cavity. The rear plate 142 is disposed on the side of the rear cover 141 near the cylinder 11 and closes the cavity to define an air supply channel 15. An air outlet 1421 is provided on the rear plate 142 to connect the air supply channel 15 with the garment processing cavity 111.

[0055] An open cavity is formed inside the rear cover 141. The rear plate 142, when fitted with the rear cover 141, closes the cavity inside the rear cover 141 and forms the air supply channel 15 in the above embodiment. The rear plate 142 ensures the sealing and integrity of the air supply channel 15. The air guide 13 is disposed inside the cavity of the rear cover 141 and can effectively guide and control the airflow flowing out from the air outlet 1223 of the fan assembly 122. The air guide 13 can guide the airflow evenly and smoothly to the air outlet 1421 on the rear plate 142, and then into the clothes processing chamber 111, reducing the noise of the airflow impacting the air supply channel 15 and allowing the airflow to enter the clothes processing chamber 111 evenly, thereby improving the clothes drying effect of the clothes processing equipment 1. The rear plate 142 is provided with an air outlet 1421 that communicates with the garment processing chamber 111. The airflow in the air supply channel 15 can enter the garment processing chamber 111 through the air outlet 1421. The design of the air outlet 1421 enables the airflow to enter the garment processing chamber 111 efficiently. In actual assembly, the number and position of the air outlets 1421 can be optimized according to the specific needs of the garment processing equipment 1 to ensure that the airflow can evenly cover all areas in the garment processing chamber 111.

[0056] The design of the rear cover 141 and the rear plate 142 improves the ease of maintenance of the garment processing equipment 1. For example, when it is necessary to clean or replace the air guide 13, the rear cover assembly 14 can be directly disassembled and the rear plate 142 opened to directly replace or repair the air guide 13, reducing maintenance costs and time. It should be noted that the air guide 13 can also be integrally formed with the rear cover 141, in which case the entire rear cover 141 can be disassembled and repaired.

[0057] According to one embodiment of the present invention, the air guide 13 includes: a main body 131, a first extension 132, and a second extension 133. The main body 131 is disposed on the rear cover 141 and extends in the height direction, dividing the cavity into a first cavity 153 and a second cavity 154. The first extension 132 is connected to one end of the main body 131 and extends toward the base 121. The first extension 132 is spaced apart from the side wall of the cavity to form a first flow channel section 151 communicating with the first cavity 153. The cross-sectional area of ​​the first flow channel section 151 gradually increases toward the first cavity 153. The second extension 133 is connected to one end of the main body 131 and extends toward the base 121. The second extension 133 is spaced apart from the side wall of the cavity to form a second flow channel section 152 communicating with the second cavity 154. The cross-sectional area of ​​the second flow channel section 152 gradually increases toward the second cavity 154.

[0058] The main body 131 is disposed on the inner wall of the cavity of the rear cover 141 and extends in the height direction, which increases the structural strength of the cavity and effectively divides the cavity into the first cavity 153 and the second cavity 154, so that the airflow can flow in two independent areas, improving the flexibility and efficiency of airflow control. The first extension 132 and the second extension 133 are respectively connected to one end of the main body 131 and extend toward the base 121. The first extension 132 and the second extension 133 define the first flow channel section 151 and the second flow channel section 152 in the cavity. The first flow channel section 151 is connected to the first cavity 153 to form a sub-air channel 150, and the second flow channel section 152 is connected to the second cavity 154 to form another sub-air channel 150. The two sub-air channels 150 can be used to plan two air supply paths in the air supply channel 15. At this time, two air outlets 1223 can be set on the fan assembly 122 to correspond to the two sub-air channels 150 respectively. The airflow from each air outlet 1223 enters the corresponding sub-air channel 150, making the airflow in the air supply channel 15 more uniform and stable.

[0059] The cross-sectional area of ​​the first flow channel section 151 gradually increases in the direction near the first cavity 153, while the cross-sectional area of ​​the second flow channel section 152 gradually increases in the direction near the second cavity 154. The design of the first flow channel section 151 and the second flow channel section 152 results in the inlet positions of the two sub-air channels 150 having gradually expanding flow channel structures. When the airflow enters the corresponding sub-air channel 150, the airflow velocity will decrease as the cross-sectional area of ​​the sub-air channel 150 increases. This helps to reduce the direct impact of the airflow on the air supply channel 15, reduce eddy currents, and at the same time, reduce noise.

[0060] According to one embodiment of the present invention, the main body 131 has a protruding turbulence portion 134 formed on at least one side in the width direction. The turbulence portion 134 enhances the disturbance of airflow when passing through the main body 131, and can prevent the airflow from forming eddies at the location of the main body 131.

[0061] According to one embodiment of the present invention, the air outlets 1421 are configured as a plurality of spaced-apart outlets on the rear plate 142, with connecting ribs 1422 provided between adjacent air outlets 1421. By spaced-aparting multiple air outlets 1421 on the rear plate 142, the airflow blown from the air outlets 1421 can be distributed more evenly, ensuring that the airflow can cover a wider area within the garment processing chamber 111, reducing airflow blind spots, and thus improving the uniformity of drying. At the same time, multiple air outlets 1421 can also increase the air intake, thereby improving the drying effect of the garment processing equipment 1. The connecting ribs 1422 provided between adjacent air outlets 1421 play a role in enhancing the structural strength. The connecting ribs 1422 can increase the overall rigidity and stability of the rear plate 142, prevent deformation or damage caused by airflow impact or vibration, and extend the service life of the rear cover assembly 14.

[0062] According to one embodiment of the present invention, a plurality of air outlets 1421 are arranged at intervals around the center of the rear plate 142, and one end of a plurality of connecting ribs 1422 is connected to each other at the center of the rear plate 142. The connection of one end of each connecting rib 1422 at the center of the rear plate 142 significantly enhances the overall rigidity and stability of the rear plate 142. Even under airflow impact or equipment vibration, the rear plate 142 can maintain good shape stability, thereby extending the service life of the garment processing equipment 1. The plurality of air outlets 1421 arranged at intervals around the center of the rear plate 142 not only increases the air intake volume but also ensures that airflow enters the garment processing chamber 111 from multiple angles, improving the drying effect of the garment processing equipment 1.

[0063] According to one embodiment of the present invention, the air duct 1211 is constructed as a straight air duct 1211 extending in a first direction. The straight air duct 1211 design simplifies the airflow path within the air duct 1211, reduces energy loss and eddies that may occur at bends or branches, and ensures smoother airflow through the air duct 1211, improving airflow delivery efficiency. Compared to the curved air duct 1211 in the prior art, the straight air duct 1211 reduces the chance of airflow collision and friction within the air duct 1211, thereby reducing the noise during operation of the garment handling equipment 1 and improving the user experience.

[0064] According to one embodiment of the present invention, the fan assembly 122 includes: a volute 1221 and an impeller 1222. The volute 1221 is disposed in the air duct 1211 and has an air outlet 1223 that is tangentially open. The impeller 1222 is rotatably disposed in the volute 1221 and has air inlets 1224 formed on both sides of the impeller 1222 in the axial direction. The volute 1221 is located inside the air duct 1211. When the airflow enters the air duct 1211 inside the base 121, it can directly enter the volute 1221 along the air duct 1211. The airflow entering the volute 1221 is driven by the impeller 1222 and discharged from the air outlet 1223 of the volute 1221. When the airflow enters the volute 1221, the airflow can enter from the air inlets 1224 on both sides of the impeller 1222 axial direction. The setting of the air inlets 1224 on both sides increases the air intake volume. When the airflow leaves the volute 1221, the air outlet 1223 is tangentially open in the volute 1221. The tangential airflow can reduce the impact of the airflow on the inner wall of the housing, reduce the energy loss of the airflow, and ensure that the airflow has a stable speed when flowing out of the volute 1221, so that the airflow can flow normally into the clothing processing chamber 111. At the same time, it also reduces the noise generated in the fan assembly 122.

[0065] In some embodiments, a protrusion 1215 protruding in the extending direction of the straight air duct 1211 is formed on the base 121. An extension space 1212 for mounting the fan assembly 122 is formed within the protrusion 1215, and at least a portion of the volute 1221 is accommodated within the extension space 1212. The protrusion 1215 formed on the base 121 provides an extension space 1212 for easy assembly of the fan assembly 122, allowing the fan assembly 122 to be mounted more compactly on the base 121 without occupying additional external space, resulting in a more compact overall structure. The design of the protrusion 1215 not only provides mounting space for the fan assembly 122 but also enhances the structural stability of the base 121.

[0066] In some embodiments, the volute 1221 outlets air towards the top of the extension space 1212. This top-outlet design allows the airflow, after being accelerated by the fan assembly 122, to flow directly upwards along the outlet 1223. This top-outlet design optimizes the airflow path, reducing detours and resistance within the duct 1211, thereby improving airflow efficiency and the air delivery capacity of the fan assembly 122. Furthermore, the top-outlet design of the volute 1221 also helps reduce noise. As the airflow exits from the outlet 1223 of the volute 1221, friction and collision between the airflow and the inner wall of the duct 1211 are reduced, thus lowering noise levels.

[0067] According to one embodiment of the present invention, multiple fan assemblies 122 are configured to be spaced apart from each other within the air duct 1211, and the multiple fan assemblies 122 are coaxially arranged. Arranging multiple fan assemblies 122 within the air duct 1211 can significantly improve the airflow delivery capacity. The coordinated operation of multiple fan assemblies 122 can generate greater airflow and air pressure, thereby ensuring that the airflow can be efficiently delivered to all corners within the garment processing chamber 111. The coaxial arrangement of the fan assemblies 122 allows for a more compact arrangement within the air duct 1211, thus optimizing the space utilization of the equipment. Simultaneously, the coaxial arrangement of multiple fan assemblies 122 ensures that the airflow generated by the multiple fan assemblies 122 can simultaneously enter the corresponding sub-air duct 150, allowing the airflow within the air supply channel 15 to uniformly enter the garment processing chamber 111.

[0068] According to one embodiment of the present invention, the cross-sectional area of ​​the air outlet 1223 gradually increases in the opening direction. This gradual increase in the cross-sectional area of ​​the air outlet 1223 helps optimize airflow distribution. When airflow exits from the air outlet 1223 of the volute 1221, the gradually increasing cross-sectional area allows the airflow to be more evenly dispersed within the air duct 1211, reducing eddies at the outlet and thus reducing energy loss. Simultaneously, the gradually increasing air outlet 1223 allows for a smoother airflow transition, reducing collisions and friction at the air outlet 1223, thereby lowering the noise level of the clothing handling equipment 1 during operation.

[0069] In some embodiments, the base 121 includes a base body 1213 and a cover plate 1214. The base body 1213 defines a straight air duct 1211 with an open top. A heat exchange component 123 and a fan assembly 122 are respectively disposed on the base body 1213. The cover plate 1214 covers the top of the base body 1213 to close the straight air duct 1211. A connecting hole corresponding to the air outlet 1223 is formed on the cover plate 1214.

[0070] The base 121 consists of a base body 1213 and a cover plate 1214. The base body 1213 defines a straight air duct 1211 with an open top, while the cover plate 1214 covers the top of the base body 1213 to close the straight air duct 1211. The cooperation between the cover plate 1214 and the base body 1213 ensures the structural integrity and sealing of the base 121, effectively preventing airflow leakage and heat loss.

[0071] The connecting hole formed on the cover plate 1214 corresponding to the air outlet 1223 ensures that the airflow can flow smoothly from the air outlet 1223 of the fan assembly 122 and enter other components of the clothing processing equipment 1 along the preset airflow path, thereby optimizing the airflow path, reducing airflow resistance, and improving the air delivery efficiency and performance of the fan assembly 122.

[0072] The cover plate 1214 and the base body 1213 can be integrated or detachably connected. The integrated base 121 has high structural strength; while the detachably connected base 121 allows users to directly enter the interior of the straight air duct 1211 by removing the cover plate 1214, which facilitates the necessary installation, inspection, cleaning and maintenance of the fan assembly 122 and heat exchange components 123. This not only improves the maintainability of the garment processing equipment 1, but also reduces maintenance costs.

[0073] In some embodiments, the base assembly 12 includes a base 121, a fan assembly 122, and a heat exchange component 123.

[0074] In summary, the garment processing equipment 1 is provided with a cylinder 11, a base 121, a fan assembly 122 and a rear cover assembly 14. The cylinder 11 is located on top of the base 121, and the rear cover assembly 14 is located at the rear of the cylinder 11 and on top of the base 121, resulting in a compact structure. An air duct 1211 is formed inside the base 121, which is connected to the clothes processing chamber 111 inside the cylinder 11. The humid airflow generated after drying clothes can enter the air duct 1211 and flow along the air duct 1211. A heat exchange component 123 and a fan assembly 122 are provided inside the air duct 1211. After the humid airflow is heated by the heat exchange component 123, it generates hot air. The hot air can be guided by the fan assembly 122 and enter the air supply channel 15 inside the rear cover assembly 14 through the air outlet 1223. An air guide component 13 is provided inside the air supply channel 15, which defines multiple sub-air ducts 150 within the air supply channel 15. At the same time, multiple air outlets 1223 are provided on the fan assembly 122, which correspond one-to-one with the multiple sub-air ducts 150. The cross-sectional area of ​​each sub-air duct 150 gradually increases in the direction away from the base 121. When the airflow flows from the air outlet 1223 into the corresponding sub-air duct 150, the flow velocity decreases and the noise is reduced.

[0075] The top of the air guide 13 is provided with a turbulence section 134, which can prevent the airflow from forming eddies in the air delivery channel 15. The rear cover assembly 14 is provided with a rear cover 141 and a rear plate 142. A cavity is formed inside the rear cover 141, and the rear plate 142 closes the cavity to define the air delivery channel 15. The rear plate 142 is provided with multiple air outlets 1421 that communicate with the clothing processing chamber 111, ensuring that the airflow in each sub-air duct 150 can directly enter the clothing processing chamber 111 for drying clothes. Multiple air outlets 1421 can increase the air intake and improve the drying effect of the clothing processing equipment 1. A connecting rib 1422 is provided between two adjacent air inlets 1224. One end of the multiple connecting ribs 1422 is connected to each other at the center of the rear plate 142, which increases the structural strength of the rear plate 142.

[0076] The fan assembly 122 includes a volute 1221 and an impeller 1222. The rotation of the impeller 1222 guides airflow. The volute 1221 has a tangentially open outlet 1223 with a gradually increasing cross-sectional area in the open direction. Airflow enters axially from the volute 1221 and exits tangentially. When the airflow reaches the outlet 1223, the flow velocity decreases, reducing noise and improving user experience. During assembly, the fan assembly 122 is constructed with multiple coaxially arranged components, enabling simultaneous air intake through multiple inlets 1224 and simultaneous air outlets 1223, improving airflow efficiency. The protrusion 1215 on the base 121 provides space for the assembly of the volute 1221, making the overall structure of the base assembly 12 more compact.
