[0043] The embodiments of the utility model are described in detail below, examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as limiting the utility model.

[0044] The existing clothes treatment equipment usually has the function of drying clothes. When the clothes treatment equipment is in use, air flow enters from the base and flows through the two devices, and then enters the inner drum of the clothes treatment equipment for drying clothes through the guide of the fan assembly. For the clothes treatment equipment, the setting of the fan assembly and the structure of the base air duct will affect the flow of air flow, and then will affect the drying effect of the clothes treatment equipment. In the related technology, after the air flow passes through the two devices, it flows through the fan assembly and the rear cover through the bent air duct of the base, and then enters the inner drum of the clothes treatment equipment. The air resistance and noise are large, the air inlet amount is small, and the user experience is not good.

[0045] Reference will now be made to Figures 1-10 The base assembly according to the embodiments of the present application is described.

[0046] The base assembly 12 according to the present application comprises a base 121, a heat exchange component 123 and a fan assembly 122. The base 121 is formed with an air duct 1211 communicating with the clothes treatment cavity 111. The heat exchange component 123 is arranged in the air duct 1211 and is used for heat exchange of the air flow passing through the air duct 1211. The fan assembly 122 is accommodated in the air duct 1211 and is formed with an air outlet 1223. The fan assembly 122 is adapted to guide the air flow in the air duct 1211 to flow out. The air outlet 1223 of the fan assembly 122 is configured to gradually increase in cross-sectional area in the air outlet direction.

[0047] The base assembly 12 according to the present application is arranged with the air duct 1211 in the base 121. The air duct 1211 communicates with the clothes treatment cavity 111. After the clothes treatment equipment 1 dries clothes, the humid air can return to the air duct 1211 in the base 121. The heat exchange component 123 is arranged in the air duct 1211. The humid air entering the air duct 1211 is converted into hot air after heat exchange of the heat exchange component 123 and can return to the clothes treatment cavity 111 for drying clothes, realizing the recycling use of the air flow. The fan assembly 122 is arranged in the air duct 1211 and is located behind the heat exchange component 123. The hot air generated after heat exchange of the heat exchange component 123 can enter the fan assembly 122 and flow towards the clothes treatment cavity 111 after being guided by the fan assembly 122. The fan assembly 122 is arranged with the air outlet 1223 gradually increasing in cross-sectional area in the air outlet direction. The fan assembly 122 can increase the flow rate of the gas and change the flow direction of the gas, so that the air flow in the air duct 1211 of the base 121 flows to the clothes treatment cavity 111. The gradual increase in the cross-sectional area of the air outlet 1223 can reduce the resistance of the air flow at the outlet, so that the air flow can flow out of the fan assembly 122 more smoothly, enter other parts of the air duct 1211 or the clothes treatment cavity 111. When the air flow flows out of the air outlet 1223, the flow rate of the air flow gradually decreases, which can reduce the noise generated by the air flow and improve the user experience.

[0048] According to one embodiment of the present application, the air duct 1211 is configured as a straight air duct 1211, and the heat exchange component 123 and the fan assembly 122 are arranged in sequence in the extension direction of the straight air duct 1211. The design of the straight air duct 1211 optimizes the airflow path, and when the airflow flows in the straight air duct 1211, the resistance generated due to the bending or turning of the air duct 1211 can be reduced, so that the airflow flows more smoothly through the heat exchange component 123 and the fan assembly 122. The heat exchange component 123 and the fan assembly 122 are arranged in sequence in the straight air duct 1211, so that the humid airflow entering the air duct 1211 can be first subjected to heat exchange and then guided to flow by the fan assembly 122, thereby improving the efficiency of the hot air entering the clothes treatment cavity 111. In addition, the design of the straight air duct 1211 also helps the heat exchange component 123 to more effectively exchange heat with the airflow: since the airflow flows at a relatively uniform speed in the straight air duct 1211, the heat exchange component 123 can more fully exchange heat with the airflow, thereby improving the heat exchange efficiency.

[0049] According to one embodiment of the present application, the fan assembly 122 includes: a volute 1221 and an impeller 1222, the volute 1221 is arranged in the air duct 1211, and the volute 1221 is formed with an air outlet 1223 open in the tangential direction; the impeller 1222 is rotatably arranged in the volute 1221, and the impeller 1222 is formed with air inlets 1224 on both sides in the axial direction, which are in communication with the air duct 1211. The volute 1221 is located in the air duct 1211, and when the airflow enters the air duct 1211 in the base 121, it can directly enter the volute 1221 along the air duct 1211, and the airflow entering the volute 1221 is driven by the impeller 1222 to be 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 in the axial direction, and the arrangement of the air inlets 1224 on both sides increases the air intake; when the airflow leaves the volute 1221, the air outlet 1223 is open in the tangential direction of the volute 1221, and the airflow is discharged tangentially, which can reduce the impact of the airflow on the inner wall of the shell, reduce the energy loss of the airflow, ensure that the airflow has a stable speed when flowing out of the volute 1221, so that the airflow can normally flow into the clothes treatment cavity 111, and also reduce the noise generated in the fan assembly 122.

[0050] According to one embodiment of the present application, the fan assembly 122 is configured as multiple fan assemblies arranged in the air duct 1211 and coaxially arranged. The multiple fan assemblies 122 arranged in the air duct 1211 can significantly improve the conveying capacity of the airflow, and the multiple fan assemblies 122 work cooperatively to generate greater air volume and air pressure, thereby ensuring that the airflow can be efficiently conveyed to every corner in the clothes treatment cavity 111. The fan assemblies 122 arranged coaxially can be more compactly arranged in the air duct 1211, thereby optimizing the space utilization of the device. Meanwhile, the coaxial arrangement of the multiple fan assemblies 122 can ensure that the airflow generated by the multiple fan assemblies 122 can simultaneously enter the corresponding sub-air duct 150, so that the airflow in the air supply channel 15 can uniformly enter the clothes treatment cavity 111.

[0051] According to one embodiment of the present application, the base 121 is formed with a protrusion 1215 protruding in the extension direction of the straight air duct 1211, the protrusion 1215 is formed with an extension space 1212 for mounting the fan assembly 122, and at least part of the volute 1221 is accommodated in the extension space 1212. The protrusion 1215 formed on the base 121 provides the fan assembly 122 with an extension space 1212 for convenient assembly, so that the fan assembly 122 can be more compactly mounted on the base 121, and at the same time, does not occupy additional external space, and the overall structure is more compact. 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.

[0052] According to one embodiment of the present application, the volute 1221 discharges air towards the top of the extension space 1212. The volute 1221 discharges air towards the top of the extension space 1212, so that the airflow can directly flow upwards along the air outlet 1223 after being accelerated by the fan assembly 122. The design of the top air outlet optimizes the airflow path, reduces the turning and resistance of the airflow in the air duct 1211, thereby improving the flow efficiency of the airflow and the air supply capacity of the fan assembly 122. In addition, the design of the volute 1221 discharging air towards the top also helps to reduce noise. When the airflow flows out of the air outlet 1223 of the volute 1221, the friction and collision of the airflow with the inner wall of the air duct 1211 are reduced, thereby reducing the noise.

[0053] According to one embodiment of the present application, the base 121 comprises a base body 1213 and a cover plate 1214. The base body 1213 defines a straight air duct 1211 with an open top, and the heat exchange component 123 and the fan assembly 122 are arranged in the base body 1213. The cover plate 1214 covers the top of the base body 1213 to close the straight air duct 1211, and the cover plate 1214 is formed with a communication hole corresponding to the air outlet 1223.

[0054] The base 121 is composed of a base body 1213 and a cover plate 1214, wherein the base body 1213 defines a straight air duct 1211 with an open top, and the cover plate 1214 covers the top of the base body 1213 to close the straight air duct 1211, the cooperation of the cover plate 1214 and the base body 1213 ensures the structural integrity and sealing of the base 121, effectively preventing air leakage and heat loss.

[0055] The communication hole formed on the cover plate 1214 corresponding to the air outlet 1223 ensures that the air flow can smoothly flow out of the air outlet 1223 of the fan assembly 122 and enter other components of the clothes treatment equipment 1 along the preset air flow path, optimizing the air flow path, reducing air flow resistance, and improving the air supply efficiency and performance of the fan assembly 122.

[0056] The cover plate 1214 and the base body 1213 can be integrated or detachably connected, the integrated base 121 has high structural strength; and the detachably connected base 121 allows the user to directly access the inside of the straight air duct 1211 by detaching the cover plate 1214, facilitating the necessary installation, inspection, cleaning and maintenance work of the fan assembly 122 and the heat exchange component 123, not only improving the maintainability of the clothes treatment equipment 1, but also reducing the maintenance cost.

[0057] The clothes treatment equipment 1 according to the present application is briefly described below.

The rear part of the cylinder body 11 is provided with the rear cover assembly 14, and the bottom of the rear cover assembly 14 is connected with the base 121, that is, the cylinder body 11 and the rear cover assembly 14 are arranged on the top of the base 121 and are spaced apart in the front-rear direction, and the position arrangement of the cylinder body 11, the base 121 and the rear cover assembly 14 makes the overall structure of the clothes processing equipment 1 more compact and occupies less space. The air supply channel 15 communicated with the clothes processing cavity 111 is arranged in the rear cover assembly 14, the air outlet 1223 in the fan assembly 122 is communicated with the air supply channel 15, and the airflow can enter the air supply channel 15 after passing through the fan assembly 122 and enter the clothes processing cavity 111 along the air supply channel 15 to dry clothes, and the design of the air supply channel 15 forms direct and efficient connection between the air outlet 1223 of the fan assembly 122 and the clothes processing cavity 111, so that the airflow can be smoothly and uniformly delivered into the clothes processing cavity 111. The airflow after drying clothes forms humid gas, and the humid gas can return to the base 121 and generate high-temperature gas again through the action of the heat exchange component 123 and enter the clothes processing cavity 111 through the fan assembly 122, thereby being recycled to improve the drying effect of the clothes processing equipment 1.

[0059] According to one embodiment of the utility model, the clothes processing equipment 1 further includes: air guide piece 13, air guide piece 13 is arranged in rear cover assembly 14, and at least part of air guide piece 13 is located in air supply channel 15 and is used for guiding the airflow exported by air outlet 1223 to clothes processing cavity 111.

[0060] According to one embodiment of the utility model, fan assembly 122 is provided with multiple air outlets 1223, air guide piece 13 divides air supply channel 15 into multiple sub air ducts 150, and each sub air duct 150 is communicated with at least one air outlet 1223.

[0061] According to one embodiment of the utility model, the cross-sectional area of at least one sub air duct 150 gradually increases in the direction away from the base 121. With the gradual increase of the cross-sectional area of the sub air duct 150, the speed of the air flow when passing through the sub air duct 150 will gradually decrease, which can reduce the resistance of the air flow in the sub air duct 150 and make the air flow flow more smoothly to the clothes processing cavity 111. When the air flow passes through the gradually increasing sub air duct 150, the flow state of the air flow is more stable, which reduces the noise generated by the air flow and improves the user experience.

The arrangement of the rear plate 142 ensures the closure and integrity of the air supply channel 15. The air guide piece 13 is arranged in the cavity of the rear cover 141 and can effectively guide and control the air flow out of the air outlet 1223 of the fan assembly 122.
