[0057] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments will be described clearly and completely below by combining the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but not 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 shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not 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 a limitation on 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", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be 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 10As shown, the present invention provides a garment processing device and its drying assembly 20, wherein the drying assembly 20 includes a lower housing having a lower drying tunnel housing 212 and a lower fan housing 261, wherein the lower drying tunnel housing 212 and the lower fan housing 261 are respectively fastened to an upper drying tunnel housing 211 and an upper fan housing 26; the upper drying tunnel housing 211 is connected to the upper fan housing 26, and a sealing element is provided between the upper drying tunnel housing 211 and the upper fan housing 26.

[0061] like Figure 5 As shown, the upper shell 26 and the lower shell 261 of the fan are fastened together to form a fan housing for mounting the fan 25. The upper shell 211 and the lower shell 212 of the drying tunnel are fastened together to form a drying tunnel body 21 with an airflow channel. The fan housing is connected to the drying tunnel body 21. The drying tunnel body 21 has an air outlet, and a heating device 24 is installed inside the airflow channel.

[0062] The drying assembly 20 also includes an air guide channel 22, which has an air inlet connected to the air outlet of the drying tunnel body 21.

[0063] 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.

[0064] It is evident that the sealing performance between the fan casing and the drying tunnel 21 directly affects the drying efficiency of the garment processing equipment.

[0065] like Figure 9 As shown, the present invention provides a sealing element between the upper shell 26 of the fan and the upper shell 211 of the drying tunnel, so that the upper shell 26 of the fan and the upper shell 211 of the drying tunnel form a sealed connection, ensuring the airtightness between the fan shell and the drying tunnel 21, preventing air leakage, and thus improving drying efficiency.

[0066] In a further embodiment, the sealing element includes a body and a protruding post 271 protruding from the surface of the body; the upper shell 211 of the drying tunnel body and / or the upper shell 26 of the fan are provided with mounting holes 262; the body is sandwiched between the upper shell 211 of the drying tunnel body and the upper shell 26 of the fan, and the protruding post 271 is embedded in the mounting hole 262.

[0067] In detail, the shape and size of the upper shell 211 of the drying tunnel and the upper shell 26 of the fan should match each other at least at the connection point so that the upper shell 211 of the drying tunnel and the upper shell 26 of the fan can be assembled.

[0068] Therefore, it is understandable that the shape and size of the seal body also match the shape and size of the upper shell 211 of the drying tunnel and the upper shell 26 of the fan at the connection.

[0069] like Figure 10 As shown, for example, the body of the seal is a sheet-like sealing strip. When assembling the upper shell 211 of the drying tunnel and the upper shell 26 of the fan, the upper shell 211 of the drying tunnel can be fixedly connected to the lower shell first, then the seal can be placed at the connection between the upper shell 211 of the drying tunnel and the upper shell 26 of the fan, and finally the upper shell 26 of the fan can be fixedly connected to the lower shell. In this way, the seal is pressed between the upper shell 211 of the drying tunnel and the upper shell 26 of the fan. Furthermore, the seal can be made of flexible materials such as rubber.

[0070] Furthermore, the surface of the sealing element body is provided with several protruding protrusions 271, and the upper shell 211 of the drying tunnel body and / or the upper shell 26 of the fan are also provided with mounting holes 262. When the sealing element is placed at the connection between the upper shell 211 of the drying tunnel body and the upper shell 26 of the fan, the protrusions 271 are inserted into the mounting holes 262 accordingly. When the upper shell 26 of the fan is fixedly connected to the lower shell, the mounting holes 262 are also aligned with the protrusions 271, so that the sealing element is pressed between the upper shell 211 of the drying tunnel body and the upper shell 26 of the fan, while the protrusions 271 are fixed in the mounting holes 262, which can prevent the sealing element from slipping and further enhance the sealing performance.

[0071] Furthermore, the mounting hole 262 can be a mounting post with a through hole that protrudes outward from the outer wall of the upper casing 26 of the fan, and the through hole constitutes the mounting hole 262.

[0072] It should be noted that the assembly sequence of the above components can be adjusted according to the actual situation.

[0073] The aforementioned lower housing, upper housing 211 of the drying tunnel, and upper housing 26 of the fan may be partially or entirely sheet metal parts.

[0074] In some embodiments of the present invention, the upper shell 211 of the drying tunnel and / or the upper shell 26 of the fan are provided with grooves for mounting the main body. The grooves can further limit the sealing body and prevent the sealing element from slipping off.

[0075] In some embodiments of the present invention, such as Figure 3 and Figure 6As shown, the drying duct body 21 is further provided with a mounting port 219 opposite to the air outlet, which is formed by the ports of the upper shell 211 and the lower shell 212 of the drying duct body. Moreover, the heating device 24 comprises a heating pipe 241 and a terminal 242 provided at the end of the heating pipe 241, the heating pipe 241 is installed in the airflow channel of the drying duct body 21, the extending direction of the heating pipe 241 is consistent with the airflow direction in the drying duct body 21, and the terminal 242 is installed in the mounting port 219. Preferably, the heating pipe 241 comprises a plurality of extending sections consistent with the airflow direction in the drying duct body 21, and a bending part is arranged between the two ends of each extending section and the adjacent extending section, except for the extending section connected with the terminal 242.

[0076] In the above scheme, the mounting port 219 for mounting the terminal 242 is arranged opposite to the air outlet, and the extending direction of the heating pipe 241 is consistent with the airflow direction in the drying duct body 21, which can reduce the number of bends of the spiral heating pipe 241, and further reduce the influence of the bends on the airflow, reduce the flow loss of the airflow in the drying duct body 21, and achieve the purpose of improving the drying efficiency.

[0077] In addition, since the overall size of the clothes treatment equipment is small, the above mounting structure of the present application arranges the heating pipe 241 in the front-rear direction, maximally utilizes the channel space of the drying duct body 21, increases the area of the heating pipe 241, and improves the drying rate.

[0078] In addition, the fixing structure for fixing the end of the heating pipe 241 is arranged at the position of the drying duct body 21 close to the air outlet, the fixing structure is tightly connected with the drying duct body 21 to fix the heating pipe 241, and the stability of the heating pipe 241 is provided.

[0079] Further, the fixing structure can be a metal sheet, specifically a copper sheet, a stainless steel sheet, etc.

[0080] Further, the fan 25 is arranged in the fan housing, so that the fan housing becomes a pipeline for conveying the airflow into the drying duct body 21. In order to further increase the size of the heating pipe 241, the present application limits that the airflow direction in the fan housing and the air inlet direction in the drying duct body 21 have an included angle. The air outlet of the drying duct body 21 for arranging the heating pipe 241 can be arranged at the front side of the clothes treatment cylinder 10, and the mounting port 219 for mounting the terminal 242 can be arranged at the rear side of the clothes treatment cylinder 10, so that the drying duct body 21 can be arranged above the clothes treatment cylinder 10 from front to rear, which greatly increases the channel space of the drying duct body 21, and further makes the extending part of the heating pipe 241 as long as possible, and reduces the number of bending parts.

[0081] In the above scheme, the lower shell part 212 of the drying channel and the lower shell part 261 of the fan are integrally formed into the lower shell, which can reduce the assembly process. However, the upper shell 211 of the drying channel body and the upper shell 26 of the fan are not integrally formed. In this way, when the heating pipe 241 or the fan 25 fails, the upper shell 211 of the drying channel body or the upper shell 26 of the fan can be opened separately for maintenance or replacement.

[0082] In some embodiments of the present application, as shown in Figure 3 and Figure 4 , the outer wall of the lower shell part 212 of the drying channel is in a planar structure at the air outlet, and the upper shell 211 of the drying channel body is in a curved structure at the air outlet. The air guide channel 22 is provided with a folded edge folded outward at the air inlet end. The outer wall surface of the lower shell part 212 of the drying channel is in sealing connection with part of the folded edge 221 of the air guide channel 22, and the end of the upper shell 211 of the drying channel body is in sealing connection with the end surface of the remaining folded edge 222 of the air guide channel 22.

[0083] In detail, as shown in Figure 4 and Figure 6 , taking the case that the drying channel body 21 is arranged above the clothes treatment drum 10 of the clothes treatment device as an example, the curved structure of the upper shell 211 of the drying channel body is formed by bending the plane downward. The outer wall surface of the lower shell part 212 of the drying channel is in a planar structure at the air outlet, in other words, the side wall of the lower shell part 212 of the drying channel does not bend downward. That is to say, the air outlet of the drying channel body 21 is not provided with an elbow structure.

[0084] The folded edge arranged at one end of the air inlet of the air guide channel 22 is formed by folding outward from the end of the air inlet. Part of the folded edge 221 is used to connect with the lower shell part 212 of the drying channel, and the other part of the folded edge 221 is used to connect with the end of the upper shell 211 of the drying channel body.

[0085] In a specific scheme, the air guide channel 22 includes a first side wall, a second side wall, a third side wall and a fourth side wall connected in sequence, the width of the first side wall and the third side wall is smaller than the width of the second side wall and the fourth side wall. When the air guide channel 22 is connected with the clothes treatment drum 10, the second side wall is close to the clothes treatment drum 10, and the fourth side wall is away from the clothes treatment drum 10.

[0086] The first side wall, the second side wall, the third side wall and the fourth side wall are all folded outward to form a folded edge, therefore, the folded edge corresponding to the second side wall is the part of the folded edge 221, which is connected with the lower shell part 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 body.

[0087] When the drying duct body 21 is assembled with the air guide channel 22, the lower shell part 212 of the drying duct is first connected with the partial folded edge 221 of the air guide channel 22, and then the upper shell 211 of the drying duct is connected with the remaining folded edge 222 of the air guide channel 22, and finally the upper shell 211 of the drying duct is connected with the lower shell part 212.

[0088] In the above scheme, the drying duct body 21 is provided as a split structure of the upper shell 211 and the lower shell part 212, and the upper shell 211 and the lower shell part 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 duct body 21 and the drying air duct, and facilitates installation. At the same time, the air outlet of the drying duct body 21 does not need to be designed as a nearly 90° elbow, which reduces the processing difficulty of the drying duct body 21, thereby improving the qualified rate of the drying duct 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.

[0089] In other words, the structure of the drying duct body 21 and the connection mode between the drying duct body 21 and the air guide channel 22 are essentially that the outer wall surface of the lower shell part 212 is surface sealing connected with the partial folded edge 221 of the air guide channel 22, and the upper shell 211 is connected with the remaining folded edge 222 of the air guide channel 22.

[0090] In addition, through the above connection structure, the sealing performance between the drying duct body 21 and the air guide channel 22 can also be improved.

[0091] In some embodiments of the present application, as shown in 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 wall, forming an installation space for installing the air outlet part of the lower shell part 212. The lower shell part 212 includes a bottom wall and a side wall, and after the bottom wall of the lower shell part 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 part 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 part 212 and the upper shell 211 of the drying duct should be flush with the surface of the remaining folded edge 222.

[0092] The above scheme can increase the space at the transition between the drying duct body 21 and the air guide channel 22, and avoid the formation of vortex of heated air at this position, thereby affecting the air inlet efficiency.

[0093] In some specific embodiments of the present application, the sealing connection between the outer wall surface of the lower shell part 212 and the partial folded edge 221 of the air guide channel 22 includes the following three schemes.

[0094] The first scheme, as shown in the figure, the surface of the partial fold 221 is provided with a sealing gasket installation groove 223, the sealing gasket installation groove 223 is provided with a sealing gasket 23, the outer wall surface of the lower shell part 212 and the sealing gasket installation groove 223 jointly extrude the sealing gasket 23. Figure 4

[0095] Preferably, the surface of the partial fold 221 is provided with a recessed sealing gasket installation groove 223, the sealing gasket 23 is embedded in the sealing gasket installation groove 223, when the lower shell part 212 and the air guide channel 22 are assembled, the sealing gasket 23 can be installed in place, then the lower shell part 212 and the partial fold 221 are fixedly connected, extruding the sealing gasket 23, at the same time, the fastening surface of the lower shell part 212 is flush with the surface of the remaining fold 222, ensuring the integrity of the installation surface of the lower shell part 212 and the remaining fold 222, further improving the sealing performance.

[0096] The second scheme, the surface of the partial fold 221 is provided with a lower sealing gasket installation groove 223, the outer wall surface of the lower shell part 212 is provided with an upper sealing gasket installation groove 223, the lower sealing gasket installation groove 223 and the upper sealing gasket installation groove 223 jointly constitute a sealing gasket installation groove 223, the sealing gasket installation groove 223 is provided with a sealing gasket 23.

[0097] The difference between this scheme and the first scheme is that the sealing gasket installation groove 223 for installing the sealing gasket 23 is arranged on the surface of the partial fold 221 and the outer wall surface of the lower shell part 212. When the lower shell part 212 and the air guide channel 22 are assembled, the sealing gasket 23 can be installed in any sealing gasket installation groove 223, then the lower shell part 212 and the partial fold 221 are fixedly connected, extruding the sealing gasket 23, at the same time, the fastening surface of the lower shell part 212 is flush with the surface of the remaining fold 222, ensuring the integrity of the installation surface of the lower shell part 212 and the remaining fold 222, further improving the sealing performance.

[0098] The third scheme, the outer wall surface of the lower shell part 212 is provided with a sealing gasket installation groove 223, the sealing gasket installation groove 223 is provided with a sealing gasket 23, the sealing gasket installation groove 223 and the surface of the partial fold 221 jointly extrude the sealing gasket 23.

[0099] ​The difference between the present scheme and the first scheme is that a gasket mounting groove 223 for mounting a gasket 23 is arranged on the outer wall surface of the lower shell part 212 of the drying channel. When the lower shell part 212 of the drying channel and the air guide channel 22 are assembled, the gasket 23 can be mounted to the gasket mounting groove 223, and then the lower shell part 212 of the drying channel and the partial folded edge 221 are fixedly connected, the gasket 23 is pressed, and the fastening surface of the lower shell part 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 part 212 of the drying channel and the remaining folded edge 222, and further improve the sealing performance.

[0100] In a further scheme, as shown in Figure 5 the lower shell part 212 of the drying channel is provided with a first fastening structure 213 at the air outlet, the partial folded edge 221 is provided with a second fastening structure 224, and the first fastening structure 213 and the second fastening structure 224 are connected.

[0101] In detail, in order to further improve the sealing performance between the drying channel body 21 and the air guide channel 22, the gasket 23 is pressed, and then the lower shell part 212 of the drying channel and the partial folded edge 221 are connected by a fastener, so as to be relatively fixed, and the integrity of the mounting surface of the lower shell part 212 of the drying channel and the remaining folded edge 222 is also ensured.

[0102] In a preferred scheme, the first fastening structure 213 is a protruding lug arranged on the side wall of the lower shell part 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 part 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.

[0103] 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 a first positioning structure 214 at the air outlet, the remaining folded edge 222 of the air guide channel 22 is provided with a second positioning structure 225, and the first positioning structure 214 and the second positioning structure 225 are connected.

[0104] In detail, the shape of the drying tunnel body 21 is generally not regular. Therefore, misalignment may occur when assembling the lower shell 212 of the drying tunnel with the air guide channel 22. This invention provides positioning structures on both the lower shell 212 and the air guide channel 22. During assembly, the approximate positional relationship between the lower shell 212 and the air guide channel 22 is first determined using these positioning structures before proceeding to the next assembly step. This ensures that misalignment does not occur during the assembly of the lower shell 212 and the air guide channel 22, improving assembly accuracy and thus enhancing sealing performance. This prevents hot air leakage at the connection between the drying tunnel body 21 and the air guide channel 22, thereby ensuring the heat utilization rate of the hot air and improving the drying efficiency of the garment processing equipment.

[0105] The above-mentioned scheme has three implementation schemes for fastening and connecting the upper shell 211 of the drying tunnel, the upper shell 26 of the fan, the lower shell, and the remaining folded edge 222 of the air guide channel 22.

[0106] In the first embodiment, an upper sealing groove is provided along the contour line on the fastening surface of the upper shell 211 of the drying tunnel body; a first lower sealing groove 216 is provided along the contour line on the fastening surface of the lower shell, and a second lower sealing groove 226 is provided along the contour line on the remaining folded edge 222. The second lower sealing groove 226 and the first lower sealing groove 216 together constitute a lower sealing groove that is adapted to the upper sealing groove; a sealing ring is provided between the upper sealing groove and the lower sealing groove.

[0107] In the preferred scheme, such as Figure 6 As shown, raised ribs are provided on the mating surfaces of the upper shell 211 of the drying tunnel and the upper shell 26 of the fan to form an upper sealing groove. Raised ribs are provided on the mating surface of the lower shell to form a first lower sealing groove 216. Raised ribs are provided on the surface of the remaining folded edge 222 to form a second lower sealing groove 226. The first lower sealing groove 216 and the second lower sealing groove 226 cooperate to form a complete lower sealing groove. When assembling the upper shell 211 of the drying tunnel, the upper shell 26 of the fan, the lower shell, and the air guide channel 22, the sealing ring can be first installed into either the upper sealing groove or the lower sealing groove, and then the upper shell 211 of the drying tunnel, the upper shell 26 of the fan, the lower shell, and the air guide channel 22 are fastened and connected to compress the sealing body to achieve a sealing effect.

[0108] In the second embodiment, an upper sealing groove is provided along the contour line on the fastening surfaces of the upper shell 211 of the drying tunnel and the upper shell 26 of the fan; the fastening surface of the lower shell and the surface of the remaining folded edge 222 are planar structures; a sealing ring is provided in the upper sealing groove, and the upper sealing groove, the fastening surface of the lower shell, and the surface of the remaining folded edge 222 together press the sealing ring.

[0109] The difference between the scheme and the first scheme is that only the upper sealing groove is arranged on the buckling surface of the upper shell 211 of the drying duct body and the upper shell 26 of the fan, and the sealing effect is realized by extruding the sealing body by the buckling surface of the lower shell and the surface of the remaining folded edge 222.

[0110] The third scheme, the buckling surface of the lower shell and the surface of the remaining folded edge 222 are provided with a lower sealing groove along the contour line; the surface of the buckling surface of the upper shell 211 of the drying duct body and the upper shell 26 of the fan is a plane structure; the lower sealing groove is provided with a sealing ring, and the lower sealing groove and the buckling surface of the upper shell 211 of the drying duct body and the upper shell 26 of the fan jointly compress the sealing ring.

[0111] The difference between the scheme and the first scheme is that only the lower sealing groove is arranged on the buckling surface of the lower shell and the surface of the remaining folded edge 222, and the sealing effect is realized by extruding the sealing body by the buckling surface of the upper shell 211 of the drying duct body and the upper shell 26 of the fan.

[0112] In some embodiments of the present application, as shown in Figure 6 The upper shell 211 of the drying duct body and the upper shell 26 of the fan are respectively provided with a plurality of first connecting structures 217 for connecting with the lower shell; and the upper shell 26 of the fan is further provided with a plurality of second connecting structures 218 for connecting with the clothes treatment drum 10 of the clothes treatment equipment.

[0113] 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 lower shell is extruded and compressed. If the first connecting structure 217 between the upper shell 26 of the fan and the lower shell is loose or has other faults, the compression of the second connecting structure 218 still prevents the lower shell 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.

[0114] Preferably, the second connecting structure 218 includes a first folded part formed by folding the edge of the upper shell 26 of the fan towards the lower shell and a second folded part formed by extending the end of the first folded part outwardly; and the second folded part is provided with a through hole connected with the clothes treatment drum 10.

[0115] It should be noted that the clothes treatment drum 10 should be provided with a structure matched with the second connecting structure 218. For example, when the through hole is arranged on the second connecting structure 218, the clothes treatment drum 10 should be provided with a screw column 11, and the second connecting structure 218 and the clothes treatment drum 10 are fastened by a screw.

[0116] Preferably, the second connecting structure 218 can be led out from the first connecting structure 217.

[0117] In a further aspect, as shown in Figure 7 The outer side wall of the air guide passage 22 is provided with a third connecting structure 227 for connecting with the clothes treatment drum 10.

[0118] In the above aspect, the air guide passage 22 is arranged at the front side of the clothes treatment drum 10, and the third connecting structure 227 for connecting with the clothes treatment drum 10 is arranged on the outer side wall of the air guide passage 22, so that the stability of the connection between the drying assembly 20 and the clothes treatment drum 10 can be improved.

[0119] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application in any form. Although the present application has been described above with reference to the preferred embodiments, the present application is not intended to be limited to the above described embodiments but can be variously modified or changed by those skilled in the art without departing from the scope of the present application. Any simple modification, equivalent change and modification of the above embodiments made by those skilled in the art based on the technical spirit of the present application without departing from the scope of the present application shall still fall within the scope of the present application.
