[0046] It should be noted that the drawings and the written description are not intended to limit the scope of the present application in any way, but are merely to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments will be described clearly and completely below with reference to the drawings of 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.

[0048] 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.

[0049] 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.

[0050] As shown in Figures 1 to 10 The present application provides a ventilation assembly for a clothes treatment device and a drying assembly 20, wherein the ventilation assembly comprises a lower shell body having a drying channel lower shell part 212 and a fan lower shell part 261, and the drying channel lower shell part 212 and the fan lower shell part 261 of the lower shell body are respectively connected with a drying channel body upper shell 211 and a fan upper shell 26 by snap-fit connection; a plurality of first connecting structures 217 for fixing the fan upper shell 26 and the lower shell body relative to each other are arranged between the fan upper shell 26 and the lower shell body, and the fan upper shell 26 is further provided with a plurality of second connecting structures 218 for connecting with a clothes treatment drum 10 of the clothes treatment device; the second connecting structures 218 are formed by folding the transition section connected with the fan upper shell 26 by the first connecting structures 217 towards the lower shell body.

[0051] In detail, the first connecting structures 217 enable the fan upper shell 26 to be tightly connected with the lower shell body, avoiding the loosening between the fan upper shell 26 and the lower shell body caused by the vibration of the fan 25 during the drying process. However, the first connecting structures 217 may still be loosened under some circumstances such as long-term use. Therefore, the present application further provides the second connecting structures 218 on the fan upper shell 26 at intervals from the first connecting structures 217, and the second connecting structures 218 press and tightly squeeze the lower shell body between the fan upper shell 26 and the clothes treatment drum 10 after being connected with the clothes treatment drum 10. At this time, once the first connecting structures 217 are loosened under the action of vibration, the second connecting structures 218 are still tightly connected with the clothes treatment drum 10, and at the same time, the lower shell body is tightly pressed between the fan upper shell 26 and the lower shell body, thereby ensuring the stability of the lower shell body.

[0052] It can be seen that in the above scheme, the second connecting structure 218 is connected and fastened with the laundry treatment drum 10 at the same time, and the lower shell is also extruded and pressed. If the first connecting structure 217 between the fan upper shell 26 and the lower shell is loose or has other faults, the second connecting structure 218 still has a pressing effect to prevent 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. Moreover, the second connecting structure 218 is folded from the transition section of the first connecting structure 217 connected with the fan upper shell 26 to the direction of the lower shell, so that the first connecting structure 217 and the second connecting structure 218 can cooperate to reduce the possibility of loosening of the first connecting structure 217 and the second connecting structure 218. It can be seen that the two kinds of connecting structures provided in the application can improve the overall reliability of the drying assembly 20, improve the fault tolerance, and reduce the overall failure repair rate of the laundry treatment equipment.

[0053] In a further scheme, a plurality of first connecting structures 217 and a plurality of second connecting structures 218 are arranged at intervals along the circumference of the fan upper shell 26.

[0054] The above scheme makes the fan upper shell 26 subjected to the action of the second connecting structure 218 in the circumferential direction, so that the fan upper shell 26 is not subjected to uneven stress.

[0055] Preferably, the second connecting structure 218 includes a first folded part folded from the edge of the fan upper shell 26 to the direction of the lower shell and a second folded part extended outward from the end of the first folded part; and the second folded part is provided with a through hole connected with the laundry treatment drum 10.

[0056] It should be noted that the laundry treatment 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 laundry treatment drum 10 should be provided with a screw column 11, and the second connecting structure 218 is fastened with the laundry treatment drum 10 by a screw.

[0057] In the above scheme, the second connecting structure 218 includes a first folded part and a second folded part; the first folded part is folded from the edge of the fan upper shell 26 to the direction of the lower shell, and the second folded part is extended outward from the end of the first folded part, so that the longitudinal section of the second connecting structure 218 is in an “L” shape. Therefore, the first folded part can only rely on the fan upper shell 26 and the lower shell to increase the strength of the second connecting part.

[0058] In some embodiments of the present application, the first connecting structure 217 comprises a first lug arranged at the edge of the upper shell 26 of the fan and a second lug arranged at the edge of the lower shell and corresponding to the position of the first lug, and a fastening connector is arranged between the first lug and the second lug.

[0059] It should be noted that the first lug and the second lug are both provided with a through hole for the fastening connector to pass through.

[0060] When the upper shell of the fan and the lower shell are assembled, the positions of the first lug and the second lug are made to correspond, and the fastening connector is passed through the through holes of the first lug and the second lug to relatively fix the upper shell 26 of the fan and the lower shell.

[0061] Further, the fastening connector comprises a screw or a rivet, etc.

[0062] In the above scheme, the first lug has an arc-shaped outer edge, and the upper shell 26 of the fan also has an arc-shaped outer edge. Therefore, after the first lug is arranged at the edge of the upper shell of the fan, the arc-shaped outer edge of the first lug and the arc-shaped outer edge of the upper shell of the fan should be connected smoothly to form a transition section. When the first folding part is folded downward from the transition section to the lower shell, the first folding part forms a structure with a "<" shape in longitudinal section, so that one side of the first folding part is closer to the lower shell, and the other side is closer to the first connecting structure 217.

[0063] In some embodiments of the present application, the upper shell 211 of the drying duct body is connected with the upper shell 26 of the fan, and a sealing member is arranged between the upper shell 211 of the drying duct body and the upper shell 26 of the fan.

[0064] As shown in Figure 5 , the upper shell 26 of the fan and the lower shell part 261 of the fan are connected by buckling, and together form a fan shell for arranging the fan 25. The upper shell 211 of the drying duct body and the lower shell part 212 of the drying duct body are connected by buckling, and together form a drying duct 21 having an airflow passage. The fan shell and the drying duct 21 are in communication. The drying duct 21 has an air outlet, and a heating device 24 is arranged in the airflow passage.

[0065] The drying assembly 20 further comprises an air guide passage 22, which has an air inlet connected with the air outlet of the drying duct 21.

[0066] As shown in Figures 1 to 3 , the air outlet of the fan shell is connected with the air inlet of the drying duct 21, for guiding air into the drying duct 21 to be heated by the heating device 24. After the air is heated in the drying duct 21, it is guided into the clothes treatment drum 10 of the clothes treatment device by the air guide passage 22 to remove moisture in the clothes, achieving the purpose of drying the clothes.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] It should be noted that the assembly sequence of the above components can be adjusted according to actual conditions.

[0076] The above lower shell, the upper shell 211 of the drying channel body, and the upper shell 26 of the fan can be partially sheet metal parts or all sheet metal parts.

[0077] In some embodiments of the present application, the upper shell 211 of the drying channel body and / or the upper shell 26 of the fan are provided with grooves for mounting the body. The grooves can further limit the position of the seal body to prevent the seal from slipping off.

[0078] In some embodiments of the present application, as shown in Figure 3 and Figure 6 The drying channel body 21 of the present application is further provided with a mounting port 219 opposite the air outlet, which is formed by the ports of the upper shell 211 of the drying channel body and the lower shell 212 of the drying channel. Moreover, the heating device 24 includes 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 passage of the drying channel body 21, the extension direction of the heating pipe 241 is consistent with the airflow direction in the drying channel body 21, and the terminal 242 is installed in the mounting port 219. Preferably, the heating pipe 241 includes several extension sections consistent with the airflow direction in the drying channel body 21, and a bending portion is connected between each extension section and the adjacent extension section at both ends of each extension section, except for the extension section connected with the terminal 242.

[0079] In the above scheme, the mounting port 219 for mounting the terminal 242 is arranged opposite the air outlet, and the extension direction of the heating pipe 241 is consistent with the airflow direction in the drying channel body 21, which can reduce the number of bends of the spiral-shaped heating pipe 241, thereby reducing the influence of the bends on the airflow, reducing the flow loss of the airflow in the drying channel body 21, and achieving the purpose of improving the drying efficiency.

[0080] In addition, since the overall size of the clothes treatment device is small, the above mounting structure of the present application arranges the heating pipe 241 in the front-rear direction, maximally utilizes the passage space of the drying channel body 21, increases the area of the heating pipe 241, and improves the drying rate.

[0081] In addition, a fixing structure for fixing the end of the heating pipe 241 is further arranged at the position of the drying channel body 21 close to the air outlet, the fixing of the heating pipe 241 is realized by fastening the fixing structure and the drying channel body 21, and the stability of the heating pipe 241 is provided.

[0082] Further, the fixing structure can be a metal sheet, specifically a copper sheet, a stainless steel sheet, etc.

[0083] Further, the fan 25 is arranged in the fan housing, so that the fan housing becomes a pipeline for conveying air flow into the drying duct body 21. In order to further increase the size of the heating pipe 241, the present application limits the included angle between the air outlet direction in the fan housing and the air inlet direction in the drying duct body 21. 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 drum 10, and the mounting port 219 for mounting the terminal 242 can be arranged at the rear side of the clothes treatment drum 10. Therefore, the drying duct body 21 can be arranged from front to back above the clothes treatment drum 10, which greatly increases the passage space of the drying duct body 21, and further can make the extension of the heating pipe 241 as long as possible, and reduces the number of bending parts.

[0084] In the above scheme, the drying duct lower shell part 212 and the fan 25 lower shell are integrally formed into a lower shell body, which can reduce the assembly process. However, the drying duct body upper shell 211 and the fan upper shell 26 are not integrally formed. In this way, when the heating pipe 241 or the fan 25 fails, the drying duct body upper shell 211 or the fan upper shell 26 can be opened separately for maintenance or replacement.

[0085] In some embodiments of the present application, as shown in Figure 3 and Figure 4 , the outer wall of the drying duct lower shell part 212 is in a planar structure at the air outlet, and the drying duct body upper shell 211 is in a curved surface structure at the air outlet. The air guide passage 22 is provided with a folded edge folded outward at the end of the air inlet. The outer wall surface of the drying duct lower shell part 212 is in sealing connection with part of the folded edge 221 of the air guide passage 22, and the end of the drying duct body upper shell 211 is in sealing connection with the end surface of the remaining folded edge 222 of the air guide passage 22.

[0086] In detail, as shown in Figure 4 and Figure 6 , taking the case that the drying duct body 21 is arranged above the clothes treatment drum 10 of the clothes treatment equipment as an example, the curved surface structure of the drying duct body upper shell 211 is formed by bending downward from a plane. The outer wall surface of the drying duct lower shell part 212 is in a planar structure at the air outlet, in other words, the side wall of the drying duct lower shell part 212 does not bend downward. That is to say, the air outlet of the drying duct body 21 is not provided with an elbow structure.

[0087] The folded edge arranged at one end of the air inlet of the air guide passage 22 is formed by folding outward from the end of the air inlet. Part of the folded edge 221 is used for connection with the drying duct lower shell part 212, and the other part of the folded edge 221 is used for connection with the end of the drying duct body upper shell 211.

[0088] In specific solutions, the air guide channel 22 comprises a first side wall, a second side wall, a third side wall and a fourth side wall connected in sequence, and the widths of the first side wall and the third side wall are smaller than the widths of the second side wall and the fourth side wall. When the air guide channel 22 is connected to 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.

[0089] 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 connected to 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 connected to the upper shell 211 of the drying channel body.

[0090] When the drying channel body 21 is assembled with the air guide channel 22, the lower shell part 212 of the drying channel is first connected to the partial folded edge 221 of the air guide channel 22 in a sealed manner, and then the upper shell 211 of the drying channel body is connected to the remaining folded edge 222 of the air guide channel 22 in a sealed manner, and finally the upper shell 211 of the drying channel body is connected to the lower shell part 212 in a buckling manner.

[0091] In the above solutions, the drying channel body 21 is provided as a drying channel body upper shell 211 and a drying channel lower shell part 212 in a split structure, and the drying channel body upper shell 211 and the drying channel lower shell part 212 are connected to the air inlet of the air guide channel 22 respectively, forming a structure of partial surface sealed connection and partial end surface sealed connection, which simplifies the connection structure of the drying channel body 21 and the drying air duct, and facilitates installation.
