However, these exemplary embodiments can be implemented in various different forms, and should not be construed as being limited to the embodiments set forth herein. It should be understood that the embodiments are provided so as to make the present disclosure complete and comprehensive, and to fully convey the concept of the exemplary embodiments to those of ordinary skill in the art.

[0032] As shown in FIGS. 1 to 7, the embodiments of the present application provide a fan volute 100, a fan 200, and a laundry treating apparatus 300, in which the fan volute 100 is applied to the fan 200, and the fan 200 is applied to the laundry treating apparatus 300.

[0033] The laundry treating apparatus 300 has at least a drying function, that is, the laundry treating apparatus 300 can be a dryer or a washer-dryer. The fan 200 can be understood as a fan 200 that provides power for a drying air flow.

[0034] It can be understood that the laundry treatment apparatus 300 is mostly in the form of a drum, and the capacity of the laundry treatment apparatus 300 can be small 3-5 kg, medium 6-8 kg, large 9 kg or more, mini less than 3 kg, etc.

[0035] As shown in FIGS. 1, 2 and 5, the embodiment of the first aspect of the present application provides a fan volute 100, the fan volute 100 comprising a surrounding wall 112 and two first walls 111 arranged in pairs, the surrounding wall 112 being located between the two first walls 111 and enclosing the two first walls 111 to form a containing cavity 113 for containing an impeller 210; wherein the surrounding wall 112 is provided with a bearing structure 120 located outside the fan volute 100, the bearing structure 120 being configured to bear a fan terminal 220.

[0036] Among them, the two first walls 111 of the fan volute 100 can be perpendicular to the rotation axis of the impeller 210, that is, the two first walls 111 are distributed along the direction of the rotation axis of the impeller 210, and the surrounding wall 112 can be distributed along the radial direction of the impeller 210 on the circumferential side of the impeller 210, thereby enclosing the containing cavity 113 by the surrounding wall 112 and the two first walls 111, so that the fan volute 100 plays a good protective role for the impeller 210 and can collect and guide the gas of the impeller 210 to ensure good air outlet effect.

[0037] The fan volute 100 provided by the embodiment of the present application is provided with a bearing structure 120 located outside the fan volute 100 on the surrounding wall 112, and the bearing structure 120 is configured to bear the fan terminal 220, that is, the fan terminal 220 is installed on the surrounding wall 112 outside the fan volute 100 through the bearing structure 120, so that at least part of the fan terminal 220 is opposite to the surrounding wall 112, so that in the axial direction of the impeller 210, the size of the fan terminal 220 protruding from the first wall 111 can be minimized, or the fan terminal 220 is located between the two first walls 111, thereby minimizing the installation space of the fan volute 100. Compared with the fan terminal fixed on the top plate of the fan volute through line binding in the related art, the gap distance of the fan volute 100 along the axial direction of the impeller 210 and other components can be reduced, the design requirement of compact structure and small volume of the laundry treatment apparatus 300 can be met, so that the laundry treatment apparatus 300 can reduce the volume on the basis of maintaining the original capacity, and improve the market competitiveness.

[0038] In the related art, the fan terminal is fixed on the top plate of the fan volute by a wire tie. During the operation of the clothes treatment apparatus, the wire tie is easily loosened due to shaking, which causes the fan terminal to be separated from the fan volute, and further causes the wire to be loose or dropped, which leads to the failure of the clothes treatment apparatus. In the embodiments of the present application, the bearing structure 120 is arranged on the surrounding wall 112 of the fan volute 100, and the fan terminal 220 can be reliably and stably fixed on the fan volute 100 through the bearing structure 120, which reduces the risk of separation of the fan terminal 220 from the fan volute 100, improves the reliability of the wire, reduces the failure rate of the clothes treatment apparatus 300, and improves the reliability of the clothes treatment apparatus 300.

[0046] Further, the fan volute 100 is provided with an air inlet on a first wall 111, so that the airflow flows into the fan volute 100 through the air inlet, is acted on by the impeller 210, is guided by the volute tongue, and is discharged through the air outlet.

[0047] As shown in FIG. 1 and FIG. 3, in some possible implementation embodiments provided by the present application, in the first direction of the fan volute 100, the bearing structure 120 does not protrude from the two first walls 111, wherein the two first walls 111 are arranged at intervals in the first direction, and the first direction can be the direction indicated by the arrow X in FIG. 1.

[0048] By arranging the bearing structure 120 in the first direction of the fan volute 100 without protruding from the two first walls 111, the arrangement of the bearing structure 120 does not increase the overall space occupied by the fan volute 100 in the first direction, thereby reducing the gap distance between the first wall 111 and other components, and meeting the design requirements of compact structure and small volume of the clothes treatment equipment 300.

[0049] As shown in FIG. 1 and FIG. 3, in some possible implementation embodiments provided by the present application, the fan volute 100 comprises a first half shell 130 and a second half shell 140 which are detachably connected and enclose the accommodating cavity 113.

In some examples, the air inlet can also be formed in the first wall 1111 of the first half shell 130.

[0057] As shown in FIG. 1, FIG. 2, FIG. 4 and FIG. 5, in some possible implementation embodiments provided by the present application, the bearing structure 120 comprises a limiting portion 121, which is configured to be connected with the fan terminal 220 in one of the following manners: clamping, plugging, and screwing, so that the fan terminal 220 can be quickly and conveniently fixed on the bearing structure 120 through the limiting portion 121 of the bearing structure 120, and the fan terminal 220 is convenient to disassemble, which is conducive to improving the assembly efficiency and maintenance efficiency of the fan 200, and is suitable for popularization and application.

[0058] Specifically, the limiting portion 121 can be a limiting hole, which is connected with the limiting hole through a bolt, a positioning pin or the like, so that the fan terminal 220 and the bearing structure 120 can be quickly and conveniently disassembled. Alternatively, the limiting portion 121 can be a clamping groove, a clamping hook, a plug groove or the like, so that the fan terminal 220 and the bearing structure 120 can be quickly and conveniently disassembled.

[0059] Further, the bearing structure 120 can be a plastic part, which has a certain elasticity, so that the reliability and stability of the connection between the fan terminal 220 and the bearing structure 120 can be further enhanced.

[0060] As shown in FIG. 1, FIG. 2, FIG. 4 and FIG. 5, in some possible implementation embodiments provided by the present application, the bearing structure 120 further comprises a bearing plate 122, which is connected with the surrounding wall 112, and the limiting portion 121 comprises a clamping groove connected to the bearing plate 122, and the fan terminal 220 is detachably connected with the clamping groove.

Moreover, the clamping groove can reliably and stably fix the fan terminal 220, compared with the fixing of the fan terminal in the related art through a wire, the risk of separation of the fan terminal 220 from the fan volute 100 is reduced, which is conducive to improving the reliability of the wiring, reducing the failure rate of the clothes treatment equipment 300, and improving the reliability of the clothes treatment equipment 300.

[0062] The setting of the bearing plate 122 provides reliable and stable support for the clamping groove connected to the bearing plate 122, reduces the possibility of shaking of the clamping groove during the working process of the fan 200, and then improves the reliability and stability of the fan terminal 220 clamped in the clamping groove, which is conducive to reducing the failure rate of the clothes treatment equipment 300 and improving the reliability of the clothes treatment equipment 300.
