[0045] The existing clothes treatment equipment usually has the function of drying clothes. When the clothes treatment equipment is used, the air flow enters from the base and flows through the heat exchange component, 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 air duct will affect the flow of the air flow, and then will affect the drying effect of the clothes treatment equipment. In the related art, the air flow flows through the fan assembly and the rear cover after the heat exchange component and then enters the inner drum of the clothes treatment equipment through the bent air duct of the base. Therefore, the arrangement of the heat exchange component and the fan assembly will affect the flow of the air flow, and even affect the drying effect of the clothes treatment equipment.

[0046] Reference is made below to Figures 1-10 A base assembly according to an embodiment of the present application is described.

[0047] 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 out. The distance between the fan assembly 122 and the heat exchange component 123 is d, and satisfies: 30mm≤d≤40mm.

[0048] The base assembly 12 is provided with an air duct 1211 in the base 121, the air duct 1211 is communicated 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 air duct 1211 is provided with a heat exchange component 123, 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 again, and circulation use of the airflow is realized. The fan assembly 122 is arranged in the air duct 1211 and located at the rear of 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 provided with an air outlet 1223 with gradually increasing cross-sectional area in the air outlet direction, the fan assembly 122 can increase the gas flow rate and change the flow direction of the gas, so that the airflow in the air duct 1211 of the base 121 flows to the clothes treatment cavity 111.

[0049] When the base assembly 12 is assembled, the fan assembly 122 and the heat exchange component 123 need to have a safety distance d, and satisfy: 30mm≤d≤40mm. When d<30mm, the distance between the fan assembly 122 and the heat exchange component 123 is too close, which can cause uneven heat exchange of the airflow entering the air duct 1211, or the airflow is guided to flow out by the fan assembly 122 before complete heat exchange, which can affect the generation of hot air, and further reduce the drying effect of the clothes treatment equipment 1 on clothes. When d>40mm, the distance between the fan assembly 122 and the heat exchange component 123 is too far, due to the limited space in the base 121, the distance between the fan assembly 122 and the heat exchange component 123 is too far, which can affect the layout in the air duct 1211, and is not conducive to the arrangement of the base assembly 12.

[0050] According to an embodiment of the utility model, the air duct 1211 is constructed as a straight air duct 1211, 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, 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 heat exchanged first and then guided to flow by the fan assembly 122, and the efficiency of the hot air entering the clothes treatment cavity 111 is improved. In addition, the design of the straight air duct 1211 is also helpful for the heat exchange component 123 to heat exchange the airflow more effectively: since the airflow flows in the straight air duct 1211 at a relatively uniform speed, the heat exchange component 123 can heat exchange the airflow more fully, thereby improving the heat exchange efficiency.

[0051] According to one embodiment of the utility model, fan assembly 122 includes: volute 1221 and impeller 1222, volute 1221 is arranged in air duct 1211, and the air outlet 1223 that opens in tangential direction is formed on volute 1221, impeller 1222 is rotatably arranged in volute 1221, and the air inlet 1224 that is communicated with air duct 1211 is formed on both sides of impeller 1222 in axial direction. Volute 1221 is located in air duct 1211, when the airflow enters air duct 1211 in base 121, can directly enter volute 1221 along air duct 1211, and the airflow that enters volute 1221 is discharged from the air outlet 1223 of volute 1221 under the driving of impeller 1222, when the airflow enters volute 1221, the airflow can enter from the air inlet 1224 on both sides of impeller 1222 in axial direction, and the setting of both sides air inlet 1224 increases the air intake volume, when the airflow leaves volute 1221, the air outlet 1223 opens in the tangential direction of volute 1221, and the airflow is tangentially discharged, 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 volute 1221, make the airflow can normally flow into the clothes treatment cavity 111, and also reduce the noise generated in fan assembly 122.

[0052] According to one embodiment of the utility model, the air outlet 1223 of fan assembly 122 is configured to gradually increase in cross-sectional area in the air outlet direction. The gradually increasing cross-sectional area of the air outlet 1223 in the opening direction helps to optimize the distribution of the airflow, and when the airflow flows out of the air outlet 1223 of volute 1221, the airflow can be more evenly dispersed into the air duct 1211 due to the gradually increasing cross-sectional area of the air outlet 1223, reducing the vortex of the airflow at the outlet, thereby reducing energy loss. At the same time, the gradually increasing air outlet 1223 can make the airflow transition more smoothly, reducing the collision and friction of the airflow at the air outlet 1223, thereby reducing the noise level when the clothes treatment equipment 1 is running.

[0053] According to one embodiment of the utility model, the fan assembly 122 is configured to be arranged in multiple in the air duct 1211 and coaxially arranged. Arranging multiple fan assemblies 122 in the air duct 1211 can significantly improve the conveying capacity of the airflow, and multiple fan assemblies 122 work together to generate greater air volume and air pressure, thereby ensuring that the airflow can be efficiently delivered to every corner of the clothes treatment cavity 111. The coaxially arranged fan assemblies 122 can be more compactly arranged in the air duct 1211, thereby optimizing the space utilization of the equipment. At the same time, the coaxial arrangement of multiple fan assemblies 122 can ensure that the airflow generated by multiple fan assemblies 122 can enter the corresponding sub-air duct 150 at the same time, so that the airflow in the air supply channel 15 can uniformly enter the clothes treatment cavity 111.

[0054] According to one embodiment of the utility model, the base 121 is formed with a protruding part 1215 protruding in the extending direction of the straight air duct 1211, an extension space 1212 for mounting the fan assembly 122 is formed in the protruding part 1215, and at least part of the volute 1221 is accommodated in the extension space 1212. The protruding part 1215 formed on the base 121 provides an extension space 1212 for the fan assembly 122, facilitating assembly, so that the fan assembly 122 can be more compactly mounted on the base 121, without occupying additional external space, and the overall structure is more compact. The design of the protruding part 1215 not only provides mounting space for the fan assembly 122, but also enhances the structural stability of the base 121.

[0055] According to one embodiment of the utility model, 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 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 noise.

[0056] According to one embodiment of the utility model, 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.

[0057] The base 121 is composed of the base body 1213 and the cover plate 1214. 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 airflow leakage and heat loss.

[0058] The communication hole corresponding to the air outlet 1223 formed on the cover plate 1214 ensures that the airflow 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 predetermined airflow path, optimizes the airflow path, reduces airflow resistance, and improves the air supply efficiency and performance of the fan assembly 122.

[0062] The rear cover assembly 14 is provided with a supply air passage 15 which is in communication with the clothes treatment cavity 111. The air outlet 1223 in the fan assembly 122 is in communication with the supply air passage 15. After passing through the fan assembly 122, the airflow can enter the supply air passage 15 and then enter the clothes treatment cavity 111 along the supply air passage 15 for drying clothes.

The rear plate 142 cooperates with the rear cover 141 to close the cavity in the rear cover 141 and form the air supply channel 15 in the above-mentioned embodiments, and the provision of the rear plate 142 ensures the closure and integrity of the air supply channel 15. The air guide 13 is arranged in the cavity of the rear cover 141 and can effectively guide and control the airflow from the outlet 1223 of the fan assembly 122, and the air guide 13 can uniformly and smoothly guide the airflow to the air supply openings 1421 on the rear plate 142 and then into the clothes treatment cavity 111, thereby reducing the noise caused by the airflow impacting the air supply channel 15 and allowing the airflow to uniformly enter the clothes treatment cavity 111, thereby improving the drying effect of the clothes treatment device 1.

[0067] The rear plate 142 is provided with air supply openings 1421 that communicate with the clothes treatment cavity 111, and the airflow in the air supply channel 15 can enter the clothes treatment cavity 111 through the air supply openings 1421. The design of the air supply openings 1421 allows the airflow to efficiently enter the clothes treatment cavity 111, and in actual assembly, the number and position of the air supply openings 1421 can be optimized according to the specific needs of the clothes treatment device 1 to ensure that the airflow can uniformly cover all areas in the clothes treatment cavity 111. The design of the rear cover 141 and the rear plate 142 improves the convenience of maintaining the clothes treatment device 1, for example, when cleaning or replacing the air guide 13, the rear cover assembly 14 can be directly disassembled and the rear plate 142 can be opened to directly replace or repair the air guide 13, thereby reducing maintenance costs and time. It should be noted that the air guide 13 can also be integrally formed with the rear cover 141, at this time, the entire rear cover 141 can be disassembled and repaired.

[0068] In some embodiments, the air supply openings 1421 are configured as multiple air supply openings 1421 arranged at intervals on the rear plate 142, and a connecting rib 1422 is arranged between adjacent two air supply openings 1421. By arranging multiple air supply openings 1421 at intervals on the rear plate 142, the airflow blown out of the air supply openings 1421 can be more evenly distributed to ensure that the airflow can cover a wider area in the clothes treatment cavity 111, reducing airflow blind spots and thereby improving the uniformity of drying. At the same time, multiple air supply openings 1421 can also increase the air intake, thereby improving the drying effect of the clothes treatment device 1.

[0069] In some embodiments, the plurality of air outlets 1421 are arranged around the center of the rear plate 142, and one ends of the plurality of connecting ribs 1422 are connected to each other at the center of the rear plate 142. The connection of one ends of the plurality of connecting ribs 1422 to each other at the center of the rear plate 142 can significantly enhance the overall rigidity and stability of the rear plate 142, so that the rear plate 142 can maintain good shape stability even in the case of air flow impact or equipment vibration, thereby prolonging the service life of the clothes treatment equipment 1. The plurality of air outlets 1421 arranged around the center of the rear plate 142 not only can increase the air inlet amount, but also can ensure that the air flow enters the clothes treatment cavity 111 from multiple angles, thereby improving the drying effect of the clothes treatment equipment 1.

[0070] In some embodiments, the air guide member 13 comprises a main body portion 131, a first extension portion 132, and a second extension portion 133. The main body portion 131 is arranged on the rear cover 141 and extends in the height direction, and the main body portion 131 divides the cavity into a first cavity 153 and a second cavity 154. The first extension portion 132 is connected to one end of the main body portion 131 and extends toward the direction close to the base 121. The first extension portion 132 is arranged in a spaced manner between the side wall of the cavity and forms a first flow passage section 151 that communicates with the first cavity 153. The cross-sectional area of the first flow passage section 151 gradually increases in the direction close to the first cavity 153. The second extension portion 133 is connected to one end of the main body portion 131 and extends toward the direction close to the base 121. The second extension portion 133 is arranged in a spaced manner between the side wall of the cavity and forms a second flow passage section 152 that communicates with the second cavity 154. The cross-sectional area of the second flow passage section 152 gradually increases in the direction close to the second cavity 154.

[0071] The main body portion 131 is arranged 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 air flow can flow in two independent areas, thereby improving the flexibility and efficiency of air flow control. The first extension portion 132 and the second extension portion 133 are respectively connected to one end of the main body portion 131 and extend toward the direction close to the base 121. The arrangement of the first extension portion 132 and the second extension portion 133 in the cavity defines the first flow passage section 151 and the second flow passage section 152. The first flow passage section 151 communicates with the first cavity 153 to form a sub-air duct 150, and the second flow passage section 152 communicates with the second cavity 154 to form another sub-air duct 150. The two sub-air ducts 150 can plan two air supply paths in the air supply passage 15. At this time, two air outlets 1223 can be arranged on the fan assembly 122 to correspond to the two sub-air ducts 150. The air flow from each air outlet 1223 enters the corresponding sub-air duct 150, so that the air flow in the air supply passage 15 is more uniform and stable.

[0072] In addition, the first flow passage section 151 gradually increases in cross-sectional area in the direction close to the first cavity 153, and the second flow passage section 152 gradually increases in cross-sectional area in the direction close to the second cavity 154. The design of the first flow passage section 151 and the second flow passage section 152 makes the inlet positions of the two sub-air ducts 150 have gradually expanding flow passage structures, respectively. When the airflow enters the corresponding sub-air duct 150, the flow rate of the airflow decreases as the cross-sectional area of the sub-air duct 150 increases, which helps to reduce the direct impact of the airflow on the air supply passage 15, reduce the vortex phenomenon, and at the same time, the noise is also reduced.
