However, the first connection structure 217 may not be loosened even in some cases such as a long use time. Therefore, the present invention further provides a second connecting structure 218 on the blower upper shell 26 spaced from the first connecting structure 217, which presses the lower shell between the blower upper shell 26 and the laundry treating drum 10 after the second connecting structure 218 is connected with the laundry treating drum 10. At this time, once the first connecting structure 217 is loosened by the vibration, the second connecting structure 218 is still tightly connected with the laundry treating drum 10, and the stability of the lower casing is also ensured because the lower casing is pressed between the upper casing 26 and the lower casing.

It can be seen that, in the above solution, the second connecting structure 218 is connected and fastened with the laundry processing drum 10, and simultaneously, the lower casing is also pressed and compressed, if the first connecting structure 217 between the upper casing 26 and the lower casing of the blower has a fault such as loosening, the pressing effect of the second connecting structure 218 still prevents the lower casing 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. Moreover, the second connecting structure 218 is formed by folding the transition section of the first connecting structure 217 connected with the blower upper shell 26 in the direction of the lower shell, so that the first connecting structure 217 and the second connecting structure 218 can cooperate with each other, and the possibility that the first connecting structure 217 and the second connecting structure 218 are loosened is reduced.

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.

In the above solution, the second connecting structure 218 includes a first folded portion and a second folded portion; the first folding portion is formed by folding the edge of the upper casing 26 of the fan towards the direction of the lower casing, and the second folding portion is formed by extending the end of the first folding portion outwards, so that the longitudinal section of the second connecting structure 218 is in an L-shaped structure. Therefore, the first folded portion can be formed only by the blower upper case 26 and the lower case, and the strength of the second connecting portion can be increased.

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.

In the above scheme, the drying tunnel lower shell part 212 and the fan 25 lower shell 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 breaks down, 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.

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.

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.

In the first scheme, as shown in fig. 4, a gasket installation groove 223 is formed on the surface of the partial flange 221, a gasket 23 is disposed in the gasket installation groove 223, and the gasket 23 is compressed by the outer wall surface of the drying tunnel lower shell portion 212 and the gasket installation groove 223 together.

Preferably, a concave gasket mounting groove 223 is formed on the surface of the partial folded edge 221, so that the gasket 23 is embedded into the gasket mounting groove 223, when the drying tunnel lower shell portion 212 and the air guide channel 22 are assembled, the gasket 23 can be mounted in place, then the drying tunnel lower shell portion 212 and the partial folded edge 221 are fixedly connected, the gasket 23 is pressed, and meanwhile, the buckling surface of the drying tunnel lower shell portion 212 is flush with the surface of the residual folded edge 222, so that the integrity of the mounting surface of the drying tunnel lower shell portion 212 and the residual folded edge 222 is ensured, and the sealing performance is further improved.
