As shown in fig. 5, the blower upper casing 26 and the blower lower casing 261 are connected in a snap-fit manner to form a blower housing for installing the blower 25. The drying tunnel upper shell 211 is connected with the drying tunnel lower shell 212 in a buckling way, and the drying tunnel upper shell and the drying tunnel lower shell together enclose the drying tunnel body 21 with an airflow channel. The fan shell is communicated with the drying tunnel body 21. The drying tunnel body 21 is provided with an air outlet, and a heating device 24 is arranged in the air flow channel.

The drying assembly 20 further comprises an air guide channel 22, the air guide channel 22 is provided with an air inlet, and the air inlet is connected with an air outlet of the drying tunnel body 21.

As shown in fig. 1 to 3, the air outlet of the blower housing is connected to the air inlet of the drying tunnel body 21, and is used for introducing air into the drying tunnel body 21 and heating the air by the heating device 24. After heated and raised in the drying tunnel body 21, the air is guided into the clothes treatment drum 10 of the clothes treatment equipment through the air guide channel 22 to remove moisture in the clothes, so that the clothes are dried.

It can be seen that the sealing performance between the blower housing and the drying tunnel body 21 directly affects the drying efficiency of the laundry treating apparatus.

As shown in fig. 9, in the present invention, a sealing member is disposed between the blower fan upper shell 26 and the drying tunnel body upper shell 211, so that a sealing connection relationship is formed between the blower fan upper shell 26 and the drying tunnel body upper shell 211, thereby ensuring the sealing property between the blower fan outer shell and the drying tunnel body 21, preventing air leakage, and further improving the drying efficiency.

In a further aspect, the seal includes a body and a post 271 protruding from a surface of the body; the drying tunnel body upper shell 211 and/or the fan upper shell 26 are/is provided with mounting holes 262; the body is clamped between the drying tunnel body upper shell 211 and the fan upper shell 26, and the convex column 271 is embedded in the mounting hole 262.

In detail, the shape and size of the drying tunnel upper shell 211 and the blower upper shell 26 at least at the connection part should be matched with each other, so that the drying tunnel upper shell 211 and the blower upper shell 26 can be completely assembled.

Thus, it will be appreciated that the shape and size of the body of the seal also matches the shape and size of the connection between the drying tunnel body top 211 and the blower top 26.

As shown in fig. 10, for example, the sealing member body is a sealing strip of a sheet structure, when the drying tunnel upper shell 211 and the blower upper shell 26 are assembled, the drying tunnel upper shell 211 and the lower shell are fixedly connected, the sealing member is padded at the connection position of the drying tunnel upper shell 211 and the blower upper shell 26, and finally the blower upper shell 26 and the lower shell are fixedly connected, so that the sealing member is compressed between the drying tunnel upper shell 211 and the blower upper shell 26. Further, the sealing member may be made of a flexible material such as rubber.

And, still there are several convex columns 271 that are outstanding on the surface of the body of the sealing element, still there are mounting holes 262 on the upper casing 211 of drying tunnel and/or blower upper casing 26, when cushioning the sealing element in the junction of upper casing 211 of drying tunnel and blower upper casing 26, plug the convex column 271 into mounting hole 262 correspondingly, when fixedly connecting upper casing 26 of blower with lower casing, also aim at the convex column 271 with the mounting hole 262, make the sealing element be compressed tightly between upper casing 211 of drying tunnel and blower upper casing 26 and fixed in mounting hole 262 again while the convex column 271, can prevent the sealing element from slipping, have further strengthened the sealing performance.

Further, the mounting hole 262 may be a mounting post having a through hole protruding outward from the outer wall of the blower upper shell 26, and the through hole forms the mounting hole 262.

The assembling sequence of the above components can be adjusted according to actual conditions.

The lower shell, the drying tunnel upper shell 211 and the blower upper shell 26 may be partially or entirely made of sheet metal.

In some embodiments of the present invention, the drying tunnel body upper shell 211 and/or the blower upper shell 26 are provided with a groove for mounting the body. The groove can further limit the sealing element body to prevent the sealing element from slipping.

In some embodiments of the present invention, as shown in fig. 3 and 6, the drying tunnel body 21 of the present invention is further provided with a mounting opening 219 opposite to the air outlet, and the mounting opening 219 may be formed by notches respectively provided on the upper and lower drying

tunnel casing portions

211 and 212. Furthermore, the heating device 24 includes a heating pipe 241 and a connection terminal 242 disposed at an end of the heating pipe 241, the heating pipe 241 is installed in the airflow channel of the drying tunnel body 21, an extending direction of the heating pipe 241 is consistent with an airflow direction in the drying tunnel body 21, and the connection terminal 242 is installed in the installation opening 219. Preferably, the heating pipe 241 includes a plurality of extension sections that are consistent with the direction of the airflow in the drying tunnel body 21, and except for the extension section connected to the connection terminal 242, a bending part is connected between each of two ends of each extension section and the adjacent extension section.

In the above scheme, the mounting opening 219 for mounting the connection terminal 242 is arranged opposite to the air outlet, and the extending direction of the heating pipe 241 is made to be consistent with the direction of the air flow in the drying tunnel body 21, so that the number of bends of the heating pipe 241 with the spiral structure can be reduced, the influence of the bends on the air flow is reduced, the flow loss of the air flow in the drying tunnel body 21 is reduced, and the purpose of improving the drying efficiency is achieved.

In addition, because the overall size of the clothes processing equipment is smaller, the heating pipe 241 is arranged in the front-back direction by the installation structure of the utility model, the channel space of the drying tunnel body 21 is utilized to the maximum extent, the area of the heating pipe 241 is enlarged, and the drying rate is improved.

In addition, a fixing structure for fixing the end of the heating pipe 241 is further arranged at a position of the drying tunnel body 21 close to the air outlet, and the fixing structure is tightly connected with the drying tunnel body 21 to fix the heating pipe 241, so that the stability of the heating pipe 241 is improved.

Further, the fixing structure may be a metal sheet, specifically, a copper sheet, a stainless steel sheet, or the like.

Further, the blower 25 is disposed in the blower housing, so that the blower housing becomes a pipeline for conveying airflow into the drying tunnel body 21, and in order to further increase the size of the heating pipe 241, an included angle is defined between an air outlet direction in the blower housing and an air inlet direction in the drying tunnel body 21. The air outlet of the drying tunnel body 21 for installing the heating pipe 241 can be arranged at the front side of the clothes treatment drum 10, and the installation port 219 for installing the connection terminal 242 can be arranged at the rear side of the clothes treatment drum 10, therefore, the drying tunnel body 21 can be arranged above the clothes treatment drum 10 from front to back, the passage space of the drying tunnel body 21 is greatly increased, the extension part of the heating pipe 241 can be made as long as possible, and the number of the bending parts is reduced.

In the above scheme, the drying tunnel lower shell part 212 and the fan lower shell part 261 are integrally formed into the lower shell, so that the assembly process can be reduced, but the drying tunnel upper shell 211 and the fan upper shell 26 are not integrally formed, so that when the heating pipe 241 or the fan 25 fails, the drying tunnel upper shell 211 or the fan upper shell 26 can be independently opened for maintenance and replacement.

In some embodiments of the present invention, as shown in fig. 3 and 4, the outer wall of the lower drying tunnel shell 212 has a planar structure at the air outlet, and the upper drying tunnel shell 211 has a curved structure at the air outlet. The end of the air guide channel 22 at the air inlet is provided with a folded edge which is folded outwards. The outer wall surface of the drying tunnel lower shell part 212 is hermetically connected with a part of folded edges 221 of the air guide channel 22, and the end part of the drying tunnel upper shell 211 is hermetically connected with the end surface of the rest folded edges 222 of the air guide channel 22.

In detail, as shown in fig. 4 and 6, taking the example that the drying tunnel body 21 is disposed above the laundry treating drum 10 of the laundry treating apparatus, the curved surface structure of the drying tunnel body upper shell 211 is formed by bending downward from a flat surface. The outer wall surface of the drying tunnel lower casing part 212 is in a plane structure at the air outlet, in other words, the side wall of the drying tunnel lower casing part 212 is not bent downward. That is, the air outlet of the drying tunnel body 21 is not provided with an elbow structure.

The folded edge arranged at one end of the air inlet of the air guide channel 22 is formed by folding the end part of the air inlet outwards. One part of the flap 221 is for coupling with the lower shell portion 212 of the drying tunnel and the other part of the flap 221 is for coupling with the end of the upper shell 211 of the drying tunnel.

In a specific scheme, the air guide channel 22 comprises a first side wall, a second side wall, a third side wall and a fourth side wall which are sequentially connected end to end, and the width of the first side wall and the width of the third side wall are smaller than the width of the second side wall and the width of the fourth side wall. When the air guiding channel 22 is connected with the laundry treating drum 10, the second sidewall is close to the laundry treating drum 10, and the fourth sidewall is far from the laundry treating drum 10.

The first side wall, the second side wall, the third side wall and the fourth side wall are all turned outwards to form a folded edge, and therefore, the folded edge corresponding to the second side wall is the partial folded edge 221 and is connected with the drying tunnel lower shell part 212. The folded edges corresponding to the first side wall, the third side wall and the fourth side wall are the residual folded edges 222 and are connected with the drying tunnel body upper shell 211.

When the drying tunnel body 21 is assembled with the air guide passage 22, the drying tunnel lower shell portion 212 is firstly connected with part of the folding edge 221 of the air guide passage 22 in a sealing manner, then the drying tunnel body upper shell 211 is connected with the rest folding edge 222 of the air guide passage 22 in a sealing manner, and then the drying tunnel body upper shell 211 is connected with the drying tunnel lower shell portion 212 in a buckling manner.

In the above scheme, the drying tunnel body 21 is provided with the drying tunnel body upper shell 211 and the drying tunnel lower shell 212 which are in split structures, and the drying tunnel body upper shell 211 and the drying tunnel lower shell 212 are respectively connected with the air inlet of the air guide channel 22, so that a structure with part of surfaces in sealing connection and part of end surfaces in sealing connection is formed, the connection structure of the drying tunnel body 21 and the drying air channel is simplified, and the installation is convenient. Meanwhile, the air outlet of the drying tunnel body 21 is not required to be designed to be an elbow of approximately 90 degrees, the processing difficulty of the drying tunnel body 21 is reduced, the qualification rate of the drying tunnel body 21 product is improved, the purpose of reducing the cost of the drying component 20 is achieved, and the market competitiveness of the clothes treatment equipment is integrally improved.

In other words, the structure of the drying tunnel body 21 and the connection manner with the air guide passage 22 according to the present invention are substantially that the outer wall surface of the drying tunnel lower casing portion 212 and the partial folded edge 221 of the air guide passage 22 are connected in a surface sealing manner, and the drying tunnel body upper casing 211 is connected in a snap-fit manner with the drying tunnel lower casing portion 212 and the residual folded edge 222 of the air guide passage 22.

In addition, the sealing performance between the drying tunnel body 21 and the air guide passage 22 can be improved by the above connection structure.

In some embodiments of the present invention, as shown in fig. 4, 6 and 8, the surface of the partial folded edge 221 formed by folding the second side wall is located at a lower level than the surface of the remaining folded edge 222 formed by folding the remaining side wall, so as to form an installation space for installing the air outlet portion of the lower housing part 212 of the drying tunnel. The drying tunnel lower shell part 212 comprises a bottom wall and side walls, and after the bottom wall of the drying tunnel lower shell part 212 is connected with the folded edges of the second side walls, the upper edges of the side walls at the air outlet of the drying tunnel lower shell part 212 are flush with the surfaces of the folded edges formed by folding the first side walls, the third side walls and the fourth side walls. In other words, the fastening surface of the lower drying tunnel shell 212 and the upper drying tunnel shell 211 should be flush with the surface of the remaining folded edge 222.

The space of the switching part of the drying tunnel body 21 and the air guide channel 22 can be enlarged by the scheme, and the phenomenon that the heated air forms vortex at the switching part to influence the air inlet efficiency is avoided.

In some embodiments of the present invention, the sealing connection between the outer wall surface of the drying tunnel lower shell 212 and the partial flap 221 of the air guide channel 22 includes the following three schemes.

The present solution is different from the first solution in that a gasket mounting groove 223 for mounting a gasket 23 is provided on both the surface of the partial flange 221 and the outer wall surface of the drying tunnel lower shell portion 212. When the drying tunnel 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 drying tunnel lower shell part 212 is fixedly connected with the partial folding edge 221, the sealing gasket 23 is pressed, and meanwhile, the buckling surface of the drying tunnel lower shell part 212 is flush with the surface of the residual folding edge 222, the integrity of the installation surface of the drying tunnel lower shell part 212 and the residual folding edge 222 is ensured, and the sealing performance is further improved.

In a further aspect, as shown in fig. 5, the drying tunnel lower shell part 212 is provided with a first fastening structure 213 at the air outlet, the partial flap 221 is provided with a second fastening structure 224, and the first fastening structure 213 and the second fastening structure 224 are connected.

In detail, in order to further improve the sealing performance between the drying tunnel body 21 and the air guide channel 22, after the sealing gasket 23 is pressed, the drying tunnel lower shell part 212 and the partial folding edge 221 are connected by a fastening piece to be relatively fixed, and the integrity of the mounting surface of the drying tunnel lower shell part 212 and the residual folding edge 222 can be ensured.

According to the utility model, the positioning structures are arranged on the drying tunnel lower shell part 212 and the air guide channel 22, when in assembly, the approximate position relation between the drying tunnel lower shell part 212 and the air guide channel 22 is determined through the positioning structures, and then the next assembly process is carried out, so that the condition that the assembly of the drying tunnel lower shell part 212 and the air guide channel 22 is not staggered can be ensured, the assembly precision is improved, the sealing performance is further improved, the hot air is prevented from leaking at the connecting part of the drying tunnel body 21 and the air guide channel 22, the heat utilization rate of the hot air is further ensured, and the drying energy efficiency of the clothes treatment equipment is improved.

In the above-mentioned solutions, there are three embodiments as follows for the solution of the fastening connection of the upper drying tunnel body 211, the upper blower housing 26, the lower housing, and the remaining folded edge 222 of the air guiding channel 22.

In the first scheme, an upper sealing groove is formed in the buckling surface of the drying tunnel body upper shell 211 along the contour line; a first lower sealing groove 216 is formed in the upper edge of the buckling surface of the lower shell, a second lower sealing groove 226 is formed in the upper edge of the residual folded edge 222, and the second lower sealing groove 226 and the first lower sealing groove 216 jointly 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.

In a preferred embodiment, as shown in fig. 6, a convex rib is disposed on a fastening surface of the drying tunnel upper shell 211 and the blower upper shell 26 to form an upper sealing groove, a convex rib is disposed on a fastening surface of the lower shell to form a first lower sealing groove 216, and a convex rib is disposed on a surface of the remaining folded edge 222 to form a second lower sealing groove 226. Wherein first lower seal groove 216 and second lower seal groove 226 cooperate together to form a completed lower seal groove. When the drying tunnel body upper shell 211, the fan upper shell 26, the lower shell and the air guide channel 22 are assembled, the sealing ring can be firstly installed in any one of the upper sealing groove or the lower sealing groove, and then the drying tunnel body upper shell 211, the fan upper shell 26, the lower shell and the air guide channel 22 are buckled and connected with the extrusion sealing body to realize the sealing effect.

In the second scheme, upper sealing grooves are formed in the buckling surfaces of the drying tunnel body upper shell 211 and the fan upper shell 26 along the contour lines; the buckling surface of the lower shell and the surface of the residual folded edge 222 are of a planar structure; a sealing ring is arranged in the upper sealing groove, and the sealing ring is compressed together with the buckling surface of the lower shell and the surface of the residual folded edge 222.

The difference between this scheme and the first scheme is that only the upper sealing grooves are arranged on the fastening surfaces of the drying tunnel body upper shell 211 and the fan upper shell 26, and the sealing body is jointly extruded by using the fastening surface of the lower shell and the surface of the residual folded edge 222 to realize the sealing effect.

In the third scheme, a lower sealing groove is formed in the surface of the residual folding edge 222 and the buckling surface of the lower shell along the contour line; the surfaces of the buckling surfaces of the drying tunnel body upper shell 211 and the fan upper shell 26 are of a plane structure; and a sealing ring is arranged in the lower sealing groove, and the lower sealing groove and the buckling surfaces of the drying tunnel body upper shell 211 and the fan upper shell 26 are jointly pressed on the sealing ring.

The difference between this scheme and the first scheme is that only the fastening surface of the lower shell and the surface of the residual folded edge 222 are provided with lower sealing grooves, and the sealing effect is realized by extruding the sealing bodies through the fastening surfaces of the drying tunnel body upper shell 211 and the fan upper shell 26.

In some embodiments of the present invention, as shown in fig. 6, a plurality of first connecting structures 217 are respectively disposed on the drying tunnel upper shell 211 and the blower upper shell 26 for connecting with the lower shell; the blower upper shell 26 is further provided with a plurality of second connecting structures 218 for connecting with the clothes treating drum 10 of the clothes treating apparatus.

In the above scheme, the second connecting structure 218 is connected and fastened with the laundry processing drum 10, and simultaneously, the lower shell is also extruded and compressed, if the first connecting structure 217 between the upper shell 26 and the lower shell of the fan loosens and other faults occur, the compressing effect of the second connecting structure 218 still prevents the lower shell from loosening. If the second connecting structure 218 is loosened, the first connecting structure 217 still functions, so that the sealing performance of the drying assembly 20 is not affected. Therefore, the utility model is provided with the connecting structure with two functions, which can improve the overall reliability of the drying component 20 and the fault tolerance rate.

Preferably, the second connecting structure 218 includes a first folded portion formed by folding the edge of the blower upper casing 26 toward the lower casing, and a second folded portion formed by extending an end of the first folded portion; the second folding part is provided with a through hole connected with the clothes treatment drum 10.

It should be noted that the laundry treating drum 10 should be provided with a structure adapted to the second connecting structure 218. For example, when the second connecting structure 218 is provided with a through hole, the laundry treating drum 10 should be provided with a screw post 11, and the second connecting structure 218 is fastened with the laundry treating drum 10 by a screw.

Preferably, the second connecting structure 218 may be led out of the first connecting structure 217.

In a further aspect, as shown in fig. 7, a third connecting structure 227 for connecting with the laundry processing drum 10 of the laundry processing apparatus is provided on an outer side wall of the air guiding channel 22.

In the above-mentioned solution, the wind guiding channel 22 is disposed at the front side of the laundry treating drum 10, and therefore, the third connecting structure 227 for connecting with the laundry treating drum 10 is disposed on the outer side wall of the wind guiding channel 22, which can improve the stability of the connection between the drying module 20 of the present invention and the laundry treating drum 10.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
