DETAILED DESCRIPTION

[0029] In the following description, a large number of specific details are given to provide a more thorough understanding of the technical solution provided by the utility model. However, it is obvious to those skilled in the art that the technical solution provided by the utility model can be implemented without one or more of these details.

[0030] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of the features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0031] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0032] like Figures 1 to 7As shown, an embodiment of the utility model provides a fan volute 100, a fan 200 and a clothes processing device 300, wherein the fan volute 100 is applied to the fan 200, and the fan 200 is applied to the clothes processing device 300200.

[0033] The clothes processing device 300 at least has a drying function, that is, the clothes processing device 300 can be a drying machine or a washing and drying machine. The fan 200 can be understood as a fan 200 that provides power for the drying airflow.

[0034] It is understandable that the clothing processing device 300 is mostly in the form of a drum, and the capacity of the clothing processing device 300 can be small 3-5 kg, medium 6-8 kg, large 9 kg and above, mini less than 3 kg, etc.

[0035] like Figure 1 , Figure 2 and Figure 5 As shown, an embodiment of the first aspect of the utility model provides a fan volute 100, which includes a surrounding wall 112 and two first walls 111 arranged in pairs, wherein the surrounding wall 112 is located between the two first walls 111 and together with the two first walls 111 forms an accommodating cavity 113 for accommodating an impeller 210; wherein a bearing structure 120 located outside the fan volute 100 is provided on the surrounding wall 112, and the bearing structure 120 is 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 spaced apart along the rotation axis direction of the impeller 210, and the surrounding wall 112 can be distributed on the peripheral side of the impeller 210 along the radial direction of the impeller 210. Thus, the surrounding wall 112 and the two first walls 111 are combined to form a accommodating cavity 113, so that the fan volute 100 has a good protective effect on the impeller 210, and can collect and guide the gas of the impeller 210 to ensure a good air outlet effect.

[0037] The fan volute 100 provided by the embodiment of the utility model has 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 a part of the fan terminal 220 is opposite to the surrounding wall 112, so that along 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, the installation space of the fan volute 100 can be minimized, compared with the related art in which the fan terminal is fixed to the top plate of the fan volute by wire ties, the gap distance between the fan volute 100 and other components along the axial direction of the impeller 210 can be reduced, and the design requirements of the clothing processing device 300 with a compact structure and a small volume can be met, so that the clothing processing device 300 can reduce the volume while maintaining the original capacity, thereby improving the market competitiveness.

[0038] Among them, in the related art, the fan terminal is fixed to the top plate of the fan volute by a wire tie. The shaking during the operation of the clothing processing device can easily loosen the wire tie, causing the fan terminal to separate from the fan volute, thereby causing the wiring to loosen or drop, resulting in a failure of the clothing processing device. In the embodiment of the utility model, by providing a bearing structure 120 on the surrounding wall 112 of the fan volute 100, the fan terminal 220 can be reliably and stably fixed on the fan volute 100 through the bearing structure 120, reducing the risk of separation of the fan terminal 220 from the fan volute 100, which is conducive to improving the reliability of the wiring, reducing the failure rate of the clothing processing device 300, and improving the reliability of the clothing processing device 300.

[0039] like Figure 2 Figure 4 and Figure 5 As shown, in some possible embodiments provided by the present invention, the surrounding wall 112 includes a volute tongue section 1121, and a first air outlet section 1122 and a volute section 1123 located on both sides of the volute tongue section 1121. The volute section 1123 is opposite to the impeller 210, that is, the volute section 1123 can be understood as matching the outer contour of the impeller 210. Among them, the volute tongue section 1121 is recessed into the interior of the accommodating cavity 113 to prevent part of the gas from circulating inside the fan volute 100, so as to ensure that the fan volute 100 has a good air outlet effect.

[0040] Among them, the volute tongue section 1121 and the first air outlet section 1122 and the volute section 1123 form a accommodating space 114 located outside the fan volute 100, that is, the accommodating space 114 is roughly located in the depression formed by the volute tongue section 1121 and the first air outlet section 1122 and the volute section 1123. By positioning the supporting structure 120 in the accommodating space 114, the supporting structure 120 can effectively and fully utilize the external structural characteristics of the volute fan 200 itself, so that the setting of the supporting structure 120 will not increase, or increase as little as possible, the space occupied by the fan volute 100 as a whole, and can meet the design requirements of the clothing processing device 300 with a compact structure and a small size.

[0041] It is understandable that, under normal circumstances, due to the particularity of the position and shape of the accommodation space 114 formed by the volute tongue section 1121, the first air outlet section 1122, and the volute section 1123, no other components are set at the accommodation space 114, that is, this part of the accommodation space 114 is idle, but the accommodation space 114 still belongs to the space occupied by the fan volute 100 as a whole. The embodiment of the utility model places the bearing structure 120 in the accommodation space 114, so that the bearing structure 120 fully utilizes the idle accommodation space 114 to achieve the setting. Compared with the idle accommodation space in the related art, the space occupied by the fan volute 100 as a whole is not increased, or the space occupied by the fan volute 100 as a whole is rarely increased. Compared with the related art in which the fan terminal is fixed to the top plate of the fan volute by wire ties, the space occupied by the fan volute 100 as a whole is greatly reduced, which can meet the design requirements of the laundry processing device 300 with a compact structure and a small volume.

[0042] In some possible embodiments provided by the present invention, the bearing structure 120 is arranged on the surrounding wall 112 of the volute tongue section 1121; or, the bearing structure 120 is arranged on the surrounding wall 112 of the first air outlet section 1122; or, the bearing structure 120 is arranged on the surrounding wall 112 of the volute section 1123; or, the bearing structure 120 is arranged on the surrounding wall 112 of the volute tongue section 1121 and the first air outlet section 1122; or, the bearing structure 120 is arranged on the surrounding wall 112 of the volute tongue section 1123. 121 and the surrounding wall 112 of the snail section 1123; or, the bearing structure 120 is arranged on the surrounding wall 112 of the first air outlet section 1122 and the snail section 1123; or, the bearing structure 120 is arranged on the surrounding wall 112 of the snail tongue section 1121, the first air outlet section 1122 and the snail section 1123, thereby, the bearing structure 120 can be located in the accommodating space 114 formed by the snail tongue section 1121, the first air outlet section 1122 and the snail section 1123.

[0043] Specifically, Figure 1 , Figure 4 and Figure 5As shown, the bearing structure 120 is arranged on the surrounding wall 112 of the volute tongue section 1121, the first air outlet section 1122 and the volute section 1123, that is, the bearing structure 120 is connected to the surrounding wall 112 of the volute tongue section 1121, the first air outlet section 1122 and the volute section 1123, thereby increasing the connection area between the bearing structure 120 and the surrounding wall 112, improving the strength and reliability of the connection between the bearing structure 120 and the surrounding wall 112, which is beneficial to improving the overall reliability of the fan volute 100 and can provide reliable and stable support for the fan terminal 220.

[0044] like Figure 1 , Figure 4 and Figure 5 As shown, in some possible embodiments provided by the present invention, the surrounding wall 112 also includes a second air outlet section 1124, and the second air outlet section 1124 and the volute tongue section 1121 are distributed on both sides of the volute section 1123. The air outlet section of the fan 200 is formed between the second air outlet section 1124 and the first air outlet section 1122, that is, the second air outlet section 1124 and the first air outlet section 1122 are away from the side of the volute section 1123 and the two first walls 111 to form an air outlet, and the air outlet is located on the side of the air outlet section away from the impeller 210.

[0045] Among them, Figure 1 and Figure 3 As shown, along the direction from the first air outlet section 1122 to the second air outlet section 1124, as shown in FIG. Figure 1 In the direction indicated by the arrow Y in FIG, the bearing structure 120 does not protrude from the volute tongue section 1121. Therefore, the arrangement of the bearing structure 120 along the direction from the first air outlet section 1122 to the second air outlet section 1124 does not increase the space occupied by the fan volute 100 as a whole. The bearing structure 120 can reasonably and fully utilize the accommodating space 114 defined by the structure of the fan volute 100 itself, while meeting the design requirements of the clothing processing device 300 with a compact structure and a small size, and is suitable for popularization and application.

[0046] Furthermore, an air inlet is provided on a first wall 111 of the fan volute 100, whereby air flows into the fan volute 100 through the air inlet, is acted upon by the impeller 210, is guided by the volute tongue, and is discharged through the air outlet.

[0047] like Figure 1 and Figure 3 As shown, in some possible embodiments provided by the present invention, along 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 along the first direction, and the first direction can be as follows Figure 1 The direction is indicated by the arrow X.

[0048] By allowing the bearing structure 120 to not protrude beyond the two first walls 111 along the first direction of the fan volute 100, the arrangement of the bearing structure 120 will not increase the space occupied by the fan volute 100 as a whole along the first direction, thereby reducing the gap distance between the first wall 111 and other components, thereby meeting the design requirements of the clothing processing device 300 with a compact structure and a small size.

[0049] like Figure 1 and Figure 3 As shown, in some possible embodiments provided by the present invention, the fan volute 100 includes a first half shell 130 and a second half shell 140 that are detachably connected and enclosed to form an accommodating chamber 113. The detachable connection between the first half shell 130 and the second half shell 140 facilitates the disassembly and maintenance of the impeller 210 accommodated in the accommodating chamber 113, which is conducive to improving the assembly efficiency and maintenance efficiency of the fan 200. Specifically, the first half shell 130 and the second half shell can be detachably connected by at least one of a bolt structure, a clamping structure, a plug-in structure, and a mortise and tenon structure.

[0050] Among them, the two first walls 111 are respectively located on the first half shell 130 and the second half shell 140, and the surrounding wall 112 is located on the first half shell 130 and the second half shell 140, that is, the first half shell 130 and the second half shell 140 are distributed along the axial direction of the impeller 210, the first half shell 130 includes a first wall 111 and a part of the surrounding wall 112, and the second half shell 140 includes a first wall 111 and a part of the surrounding wall 112, and then the first half shell 130 and the second half shell are used to enclose a receiving chamber 113.

[0051] Among them, the bearing structure 120 is arranged on the first half shell 130 and / or the second half shell 140, that is, the bearing structure 120 can be arranged on the surrounding wall 112 of the first half shell 130, or, the bearing structure 120 can be arranged on the surrounding wall 112 of the second half shell 140, or, the bearing structure 120 can be arranged on the surrounding wall 112 of the first half shell 130 and the surrounding wall 112 of the second half shell 140 at the same time to meet the requirements of different structures of the bearing structure 120.

[0052] In some possible embodiments provided by the present invention, the first half shell 130 and / or the second half shell 140 are plastic parts, that is, the first half shell 130 can be a plastic part, or the second half shell 140 can be a plastic part, or both the first half shell 130 and the second half shell 140 are plastic parts. Among them, plastic parts have the advantages of light material, high hardness, strong protection, strong environmental protection, long service life, low cost, and easy molding, and are suitable for promotion and application.

[0053] The bearing structure 120 is integrally formed with the first half shell 130 and / or the second half shell 140 by injection molding. That is, when the first half shell 130 is a plastic part, the bearing structure 120 can be located on the surrounding wall 112 of the first half shell 130 and integrally formed with the first half shell 130 by injection molding; when the second half shell 140 is a plastic part, the bearing structure 120 can be located on the surrounding wall 112 of the second half shell 140 and integrally formed with the second half shell 140 by injection molding; when the first half shell 130 is a plastic part, the bearing structure 120 can be located on the surrounding wall 112 of the second half shell 140 and integrally formed with the second half shell 140 by injection molding; When the first half shell 130 and the second half shell 140 are both plastic parts, the bearing structure 120 can be located on the surrounding wall 112 of the first half shell 130 and be integrally injection molded with the first half shell 130. The bearing structure 120 can also be located on the surrounding wall 112 of the second half shell 140 and be integrally injection molded with the second half shell 140. Alternatively, the bearing structure 120 can be located on the surrounding walls 112 of the first half shell 130 and the second half shell 140 at the same time and be integrally injection molded with the first half shell 130 and the second half shell 140. This equipment simplifies the processing of the bearing structure 120, is easy to implement, is conducive to saving processing costs, and is suitable for popularization and application.

[0054] Further, when one of the first half shell 130 and the second half shell 140 is a plastic part, the materials of the first half shell 130 and the second half shell 140 can be different, such as one is a plastic part and the other is a stainless steel part, a metal part, etc., to meet the requirements of different structures of the fan volute 100. In this case, the bearing structure 120 can be integrally injection molded with the first half shell 130 or the second half shell 140 of the plastic part, simplifying the processing process of the bearing structure 120 and saving processing costs.

[0055] It can be understood that when the first half shell 130 and the second half shell 140 are both made of plastic, the load-bearing structure 120 can also be set on one of the first half shell 130 and the second half shell 140, such as the load-bearing structure 120 can be integrally injection molded with the first half shell 130, or the load-bearing structure 120 can be integrally injection molded with the second half shell 140 to improve the overall strength and reliability of the load-bearing structure 120.

[0056] Specifically, Figure 4 As shown, the first half shell 130 is a plastic part, the bearing structure 120 is arranged on the surrounding wall 1112 of the first half shell 130, the first half shell 130 is located at the top of the fan volute 100, and the second half shell 140 is located at the bottom of the fan volute. It can be understood that the air inlet is opened on the first wall 1111 of the second half shell 140. In some examples, the air inlet can also be opened on the first wall 1111 of the first half shell 130.

[0057] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, in some possible embodiments provided by the utility model, the bearing structure 120 includes a limiting portion 121, and the limiting portion 121 is configured to be connected to the fan terminal 220 in at least one of the following ways: snap-on, plug-in, and bolt connection. Thus, through the limiting portion 121 of the bearing structure 120, the fan terminal 220 can be quickly and conveniently fixed to the bearing structure 120, and the disassembly and assembly of the fan terminal 220 is convenient, which is beneficial 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 may be a limiting hole, which is connected to the limiting hole by bolts, positioning pins, etc., so that the fan terminal 220 and the bearing structure 120 can be quickly and conveniently disassembled. Alternatively, the limiting portion 121 may be a slot, a hook, a slot, etc., so that the fan terminal 220 and the bearing structure 120 can be quickly and conveniently disassembled.

[0059] Furthermore, the bearing structure 120 may be a plastic component, which has a certain elasticity, thereby further enhancing the reliability and stability of the connection between the fan terminal 220 and the bearing structure 120 .

[0060] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some possible embodiments provided by the present invention, the bearing structure 120 also includes a bearing plate 122, the bearing plate 122 is connected to the surrounding wall 112, the limiting portion 121 includes a slot connected to the bearing plate 122, and the fan terminal 220 is detachably connected to the slot.

[0061] Through the card slot, the fan terminal 220 can be snap-connected with the supporting structure 120, and then the fan terminal 220 and the card slot can be quickly disassembled and assembled, which is beneficial to improving the assembly efficiency and maintenance efficiency of the fan 200. In addition, the card slot can reliably and stably fix the fan terminal 220. Compared with the related art in which the fan terminal is fixed by tying wire, the risk of separation of the fan terminal 220 and the fan volute 100 is reduced, which is beneficial to improving the reliability of wiring, reducing the failure rate of the clothing processing device 300, and improving the reliability of the clothing processing device 300.

[0062] Among them, the setting of the supporting plate 122 provides reliable and stable support for the card slot connected to the supporting plate 122, reduces the possibility of shaking of the card slot during the operation of the fan 200, and thereby improves the reliability and stability of the fan terminal 220 connected in the card slot, which is beneficial to reducing the failure rate of the clothing processing device 300 and improving the reliability of the clothing processing device 300.

[0063] like Figure 1 and 2 As shown, in some possible embodiments provided by the present invention, the opening 1211 of the slot faces the top of the fan volute 100 , and the slot includes two buckles 1212 arranged in pairs, with an escape opening 1213 formed between the two ends of the two buckles 1212 .

[0064] Among them, since the fan 200 of the clothing processing device 300 is usually arranged close to the top of the clothing processing device 300, when the top outer shell of the clothing processing device 300 is disassembled, the top of the fan volute 100 can be exposed to the outside, that is, the first wall 111 of the fan volute 100 located at the top is exposed to the outside. Therefore, the opening 1211 of the slot is set to face the top of the fan volute 100. For example, when the supporting structure 120 does not protrude from the first wall 111 along the first direction, the opening 1211 of the slot can face the first wall 111 located at the top of the fan volute 100.

Since the clothes processing device 300 includes the aforementioned fan 200, it has all the technical effects of the aforementioned fan 200, which will not be repeated here one by one.

[0070] Furthermore, the drying channel 320 of the clothing processing device 300 is connected to the clothing accommodating chamber 310, and the fan volute 100 is connected to the drying channel 320. In this way, when the fan 200 works, it can input the drying air flow into the clothing accommodating chamber 310 through the drying channel 320 to dry the clothes in the clothing accommodating chamber 310.

[0071] Further, the fan volute 100 may be connected to one end of the drying passage 320, or the drying passage 320 may include a plurality of sections, and the fan volute 100 is connected between two adjacent sections of the drying passage 320. Figure 7 As described above, the drying channel 320 includes two sections, and the fan volute 100 is connected between the two sections.
