[0057] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0058] In the description of the present application, it should be noted that the terms “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inner”, “outer” and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are merely for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0059] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms “mounting”, “connection”, “connecting” should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection, can also be electrical connection; can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0060] As Figures 1 to 9As shown, the present invention provides a clothing processing device and its drying component, wherein the drying component 20 includes a drying tunnel 21 and an air guide channel 22, the drying tunnel 21 has an air outlet, the air guide channel 22 has an air inlet, and the air inlet is connected to the air outlet of the drying tunnel 21.

[0061] Additionally, the drying assembly 20 may also include a fan 25 and a heating device 24, with the heating device 24 disposed within the drying tunnel body 21. The fan 25 is disposed within the fan housing.

[0062] like Figures 1 to 3 As shown, the air outlet of the fan casing is connected to the air inlet of the drying tunnel 21, which is used to guide air into the drying tunnel 21 to be heated by the heating device 24. After the air is heated in the drying tunnel 21, it is guided into the clothing processing drum 10 of the clothing processing equipment through the air guide channel 22 to remove the moisture in the clothes, thereby achieving the purpose of drying the clothes.

[0063] like Figure 3 and Figure 4 As shown, the drying tunnel body 21 includes an upper drying tunnel shell 211 and a lower drying tunnel shell 212 that interlock with each other. The outer wall of the lower drying tunnel shell 212 has a planar structure at the air outlet, while the upper drying tunnel shell 211 has a curved structure at the air outlet. The air guide channel 22 has an outwardly folded edge at the end of the air inlet. The outer wall surface of the lower drying tunnel shell 212 is sealed to the surface of a portion of the folded edge 221 of the air guide channel 22, and the end of the upper drying tunnel shell 211 is sealed to the end face of the remaining folded edge 222 of the air guide channel 22.

[0064] Detailed, such as Figure 4 and Figure 6 As shown, taking the example of the drying duct 21 being positioned above the garment processing drum 10 of the garment processing equipment, the curved structure of the upper shell 211 of the drying duct is formed by bending a flat surface downwards. The outer wall of the lower shell 212 of the drying duct has a flat structure at the air outlet; in other words, the side wall of the lower shell 212 of the drying duct does not bend downwards. That is to say, the air outlet of the drying duct 21 does not have an elbow structure.

[0065] The flange located at one end of the air inlet of the air guide channel 22 is formed by folding the end of the air inlet outward. One part of the flange 221 is used to connect with the lower shell 212 of the drying tunnel, and the other part of the flange 221 is used to connect with the end of the upper shell 211 of the drying tunnel.

[0066] In the specific design, the air guide channel 22 includes a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall connected sequentially from end to end. The widths of the first and third sidewalls are smaller than the widths of the second and fourth sidewalls. When the air guide channel 22 is connected to the clothing processing drum 10, the second sidewall is closer to the clothing processing drum 10, while the fourth sidewall is farther away from the clothing processing drum 10.

[0067] The first side wall, the second side wall, the third side wall and the fourth side wall are all outwardly folded to form a folded edge, and thus the folded edge corresponding to the second side wall is the partial folded edge 221, which is connected with the lower shell 212 of the drying channel. The folded edges corresponding to the first side wall, the third side wall and the fourth side wall are the remaining folded edges 222, which are connected with the upper shell 211 of the drying channel.

[0068] When the drying channel body 21 is assembled with the air guide channel 22, the lower shell 212 of the drying channel is first connected with the partial folded edge 221 of the air guide channel 22, and then the upper shell 211 of the drying channel is connected with the remaining folded edge 222 of the air guide channel 22, and finally the upper shell 211 of the drying channel is connected with the lower shell 212 of the drying channel.

[0069] In the above scheme, the drying channel body 21 is provided as the upper shell 211 and the lower shell 212 of the drying channel in a split structure, and the upper shell 211 and the lower shell 212 are respectively connected with the air inlet of the air guide channel 22, forming a structure of partial surface sealing connection and partial end surface sealing connection, which simplifies the connection structure of the drying channel body 21 and the air guide channel 22 and facilitates installation. At the same time, the air outlet of the drying channel body 21 does not need to be designed as a nearly 90° elbow, which reduces the processing difficulty of the drying channel body 21, thereby improving the qualification rate of the drying channel body 21 product, achieving the purpose of reducing the cost of the drying assembly 20, and improving the market competitiveness of the clothes treatment equipment as a whole.

[0070] In other words, the structure of the drying channel body 21 and the connection mode between the drying channel body 21 and the air guide channel 22 are substantially that the outer wall surface of the lower shell 212 of the drying channel is surface sealing connected with the partial folded edge 221 of the air guide channel 22, and the upper shell 211 of the drying channel is connected with the lower shell 212 of the drying channel and the remaining folded edge 222 of the air guide channel 22.

[0071] In addition, through the above connection structure, the sealing performance between the drying channel body 21 and the air guide channel 22 can also be improved.

[0072] In some embodiments of the present application, as shown in Figs. Figure 4 , Figure 6 and Figure 8 , the surface of the partial folded edge 221 formed by folding the second side wall is lower than the surface of the remaining folded edge 222 formed by folding the remaining side walls, forming an installation space for installing the air outlet part of the lower shell 212 of the drying channel. The lower shell 212 of the drying channel includes a bottom wall and a side wall, and after the bottom wall of the lower shell 212 is connected with the folded edge of the second side wall, the upper edge of the side wall at the air outlet of the lower shell 212 is flush with the surface of the folded edge formed by folding the first side wall, the third side wall and the fourth side wall. In other words, the connection surface of the lower shell 212 and the upper shell 211 of the drying channel should be flush with the surface of the remaining folded edge 222.

[0073] The above solution can increase the space at the junction of the drying tunnel 21 and the air guide channel 22, and prevent the heated air from forming vortices at this point, which would affect the air intake efficiency.

[0074] In some specific embodiments of the present invention, the outer wall surface of the lower shell 212 of the drying tunnel and the partial folded edge 221 of the air guide channel 22 are sealed together in the following three ways.

[0075] The first option, such as Figure 4 As shown, a sealing gasket mounting groove 223 is provided on the surface of the partial folded edge 221, and a sealing gasket 23 is provided in the sealing gasket mounting groove 223. The outer wall surface of the lower shell 212 of the drying tunnel and the sealing gasket mounting groove 223 jointly compress the sealing gasket 23.

[0076] Preferably, a recessed sealing gasket mounting groove 223 is provided on the surface of the partial folded edge 221, so that the sealing gasket 23 is embedded in the sealing gasket mounting groove 223. When assembling the lower shell of the drying tunnel 212 and the air guide channel 22, the sealing gasket 23 can be installed in place, and then the lower shell of the drying tunnel 212 and the partial folded edge 221 can be fixedly connected, squeezing the sealing gasket 23, and at the same time making the snap-fit ​​surface of the lower shell of the drying tunnel 212 flush with the surface of the remaining folded edge 222, ensuring the integrity of the mounting surface of the lower shell of the drying tunnel 212 and the remaining folded edge 222, and further improving the sealing performance.

[0077] In the second embodiment, a lower sealing gasket mounting groove 223 is provided on the surface of the partial folded edge 221, and an upper sealing gasket mounting groove 223 is provided on the outer wall surface of the lower shell 212 of the drying tunnel. The lower sealing gasket mounting groove 223 and the upper sealing gasket mounting groove 223 together constitute the sealing gasket mounting groove 223, and a sealing gasket 23 is provided in the sealing gasket mounting groove 223.

[0078] The difference between this solution and the first solution is that sealing gasket mounting grooves 223 for mounting the sealing gasket 23 are provided on both the surface of the partial folded edge 221 and the outer wall surface of the lower shell 212 of the drying tunnel. When assembling the lower shell 212 of the drying tunnel and the air guide channel 22, the sealing gasket 23 can be installed into any sealing gasket mounting groove 223, and then the lower shell 212 of the drying tunnel and the partial folded edge 221 can be fixedly connected, pressing the sealing gasket 23, and at the same time making the snap-fit ​​surface of the lower shell 212 of the drying tunnel flush with the surface of the remaining folded edge 222, ensuring the integrity of the mounting surfaces of the lower shell 212 of the drying tunnel and the remaining folded edge 222, and further improving the sealing performance.

[0079] In the third embodiment, a sealing gasket mounting groove 223 is provided on the outer wall surface of the lower shell 212 of the drying tunnel, and a sealing gasket 23 is provided in the sealing gasket mounting groove 223. The sealing gasket mounting groove 223 and the surface of the partial folded edge 221 jointly compress the sealing gasket 23.

[0080] The difference between the scheme and the first scheme is that the sealing gasket mounting groove 223 for mounting the sealing gasket 23 is arranged on the outer wall surface of the lower shell 212 of the drying channel. When the lower shell 212 of the drying channel and the air guide channel 22 are assembled, the sealing gasket 23 can be mounted to the sealing gasket mounting groove 223, and then the lower shell 212 of the drying channel and the partial folded edge 221 are fixedly connected to extrude the sealing gasket 23, and at the same time, the fastening surface of the lower shell 212 of the drying channel is flush with the surface of the remaining folded edge 222, so as to ensure the integrity of the mounting surface of the lower shell 212 of the drying channel and the remaining folded edge 222, and further improve the sealing performance.

[0081] In a further scheme, as shown in Figure 5 the lower shell 212 of the drying channel is provided with the first fastening structure 213 at the air outlet, the partial folded edge 221 is provided with the second fastening structure 224, and the first fastening structure 213 and the second fastening structure 224 are connected.

[0082] In detail, in order to further improve the sealing performance between the drying channel body 21 and the air guide channel 22, the sealing gasket 23 is extruded, and then the lower shell 212 of the drying channel and the partial folded edge 221 are connected by the fastener to be relatively fixed, and the integrity of the mounting surface of the lower shell 212 of the drying channel and the remaining folded edge 222 is also ensured.

[0083] In a preferred scheme, the first fastening structure 213 is a protruding lug arranged on the side wall of the lower shell 212 of the drying channel, and a screw hole is arranged on the lug. Similarly, the second fastening structure 224 is a fixed plate further extended on the folded edge of the air guide channel 22, and a screw hole is also arranged on the fixed plate. When the lower shell 212 of the drying channel and the partial folded edge 221 of the air guide channel 22 are assembled in place, the lug and the fixed plate are tightened by a screw.

[0084] In some embodiments of the present application, as shown in Figures 5 to 8 the upper shell 211 of the drying channel is provided with the first positioning structure 214 at the air outlet, the remaining folded edge 222 of the air guide channel 22 is provided with the second positioning structure 225, and the first positioning structure 214 and the second positioning structure 225 are connected.

[0085] In detail, generally, the shape of the drying duct body 21 is not regular, so that misalignment may occur when the drying duct lower shell 212 and the air guide channel 22 are assembled. The present application provides positioning structures on the drying duct lower shell 212 and the air guide channel 22. When assembled, the general positional relationship between the drying duct lower shell 212 and the air guide channel 22 is first determined through the positioning structures, and then the next assembly process is performed, so that misalignment does not occur when the drying duct lower shell 212 and the air guide channel 22 are assembled, the assembly precision is improved, and the sealing performance is improved, so as to avoid leakage of hot air at the connection part between the drying duct body 21 and the air guide channel 22, and thus the heat utilization rate of the hot air is ensured, and the drying energy efficiency of the clothes treatment equipment is improved.

[0086] The above-mentioned scheme of the drying duct upper shell 211 and the drying duct lower shell 212 and the remaining folded edge 222 of the air guide channel 22 has the following three embodiments.

[0087] The first scheme is that the fastening surface of the drying duct upper shell 211 is provided with an upper sealing groove along the contour line; the fastening surface of the drying duct lower shell 212 is provided with a first lower sealing groove 216 along the contour line, and the surface of the remaining folded edge 222 is provided with a second lower sealing groove 226 along the contour line, and the second lower sealing groove 226 and the first lower sealing groove 216 together form a lower sealing groove matched with the upper sealing groove; and a sealing ring is arranged between the upper sealing groove and the lower sealing groove.

[0088] In the preferred scheme, as shown in Figure 6 the fastening surface of the drying duct upper shell 211 is provided with a convex rib to form an upper sealing groove, the fastening surface of the drying duct lower shell 212 is provided with a convex rib to form a first lower sealing groove 216, and the surface of the remaining folded edge 222 is provided with a convex rib to form a second lower sealing groove 226. Among them, the first lower sealing groove 216 and the second lower sealing groove 226 together form a completed lower sealing groove. When assembling the drying duct upper shell 211, the drying duct lower shell 212 and the air guide channel 22, the sealing body can be first installed in any one of the upper sealing groove or the lower sealing groove, and then the drying duct upper shell 211, the drying duct lower shell 212 and the air guide channel 22 are fastened and connected to extrude the sealing body to achieve the sealing effect.

[0089] The second scheme is that the fastening surface of the drying duct upper shell 211 is provided with an upper sealing groove along the contour line; the fastening surface of the drying duct lower shell 212 and the surface of the remaining folded edge 222 are flat structures; a sealing ring is arranged in the upper sealing groove, and the upper sealing groove, the fastening surface of the drying duct lower shell 212 and the surface of the remaining folded edge 222 together compress the sealing ring.

[0090] The difference between the scheme and the first scheme is that only the upper sealing groove is arranged on the fastening surface of the upper shell 211 of the drying duct, and the sealing effect is realized by extruding the sealing body by the fastening surface of the lower shell 212 of the drying duct and the surface of the remaining folded edge 222.

[0091] The third scheme, the fastening surface of the lower shell 212 of the drying duct and the surface of the remaining folded edge 222 are provided with a lower sealing groove along the contour line; the surface of the fastening surface of the upper shell 211 of the drying duct is a plane structure; the lower sealing groove is provided with a sealing ring, and the lower sealing groove and the fastening surface of the upper shell 211 of the drying duct jointly compress the sealing ring.

[0092] The difference between the scheme and the first scheme is that only the lower sealing groove is arranged on the fastening surface of the lower shell 212 of the drying duct and the surface of the remaining folded edge 222, and the sealing effect is realized by extruding the sealing body by the fastening surface of the upper shell 211 of the drying duct.

[0093] In some embodiments of the present application, as shown in Figure 5 The drying assembly 20 further comprises a fan housing, and a fan 25 is arranged in the fan housing. The fan housing comprises a fan upper shell 26 and a fan lower shell 28 which are connected by fastening. The fan lower shell 28 is integrally formed with the lower shell 212 of the drying duct, and the fan upper shell 26 is sealingly connected with the upper shell 211 of the drying duct. The fan upper shell 26 is provided with a plurality of first connecting structures 217 for connecting with the fan lower shell 28 and a plurality of second connecting structures 218 for connecting with the clothes treatment drum 10 of the clothes treatment equipment.

[0094] Preferably, the second connecting structure 218 comprises a first folded part which is formed by folding the edge of the fan upper shell 26 towards the fan lower shell 28 and a second folded part which is formed by extending the end of the first folded part outwardly. The second folded part is provided with a through hole for connecting with the clothes treatment drum 10.

[0095] In the above scheme, the second connecting structure 218 is connected and fastened with the clothes treatment drum 10, and at the same time, the fan lower shell 28 is extruded and compressed. If the first connecting structure 217 between the fan upper shell 26 and the fan lower shell 28 is loose or has other faults, the compression of the second connecting structure 218 still prevents the fan lower shell 28 from loosening. If the second connecting structure 218 is loose or has other faults, the first connecting structure 217 still has an effect, so that the sealing property of the drying assembly 20 is not affected. It can be seen that the two kinds of connecting structures provided in the present application can improve the overall reliability of the drying assembly 20 and improve the fault tolerance.

[0096] Preferably, the second connecting structure 218 comprises a first folded portion folded from the edge of the upper fan shell 26 towards the lower fan shell 28 and a second folded portion extended from the end of the first folded portion; the second folded portion is provided with a through hole for connecting with the clothes treating drum 10.

[0097] It should be noted that the clothes treating drum 10 should be provided with a structure matched with the second connecting structure 218. For example, when the second connecting structure 218 is provided with a through hole, the clothes treating drum 10 should be provided with a screw column 11 for fastening the second connecting structure 218 with the clothes treating drum 10 by a screw.
