The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 9, the present invention provides a clothes treating apparatus and a drying assembly thereof, wherein the drying assembly 20 includes a drying tunnel body 21 and an air guiding channel 22, the drying tunnel body 21 has an air outlet, the air guiding channel 22 has an air inlet, and the air inlet is connected to the air outlet of the drying tunnel body 21.

In addition, the drying assembly 20 may further include a blower 25 and a heating device 24, and the heating device 24 is disposed in the drying tunnel body 21. The fan 25 is disposed in the fan housing.

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.

One portion of the flap 221 is for attachment to the lower tunnel shell 212 and the other portion of the flap 221 is for attachment to the end of the upper tunnel shell 211.

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 folded edges, and therefore the folded edges corresponding to the second side wall are the partial folded edges 221 and are connected with the lower drying tunnel shell 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 upper shell 211.

When the drying tunnel body 21 is assembled with the air guide channel 22, firstly, the drying tunnel lower shell 212 is hermetically connected with a part of folded edges 221 of the air guide channel 22, then, after the drying tunnel upper shell 211 is hermetically connected with the rest folded edges 222 of the air guide channel 22, the drying tunnel upper shell 211 is buckled with the drying tunnel lower shell 212.

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 lower drying tunnel shell 212 is in surface sealing connection with the partial folded edge 221 of the air guide passage 22, and the upper drying tunnel shell 211 is in snap-fit connection with the lower drying tunnel shell 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 lower than the surface of the remaining folded edge 222 formed by folding the remaining side wall, so as to form a mounting space for mounting the air outlet portion of the lower shell 212 of the drying tunnel. The lower drying tunnel shell 212 comprises a bottom wall and side walls, and after the bottom wall of the lower drying tunnel shell 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 lower drying tunnel shell 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.

The present embodiment is different from the first embodiment in that a gasket installation groove 223 for installing a gasket 23 is provided on both the surface of the partial flange 221 and the outer wall surface of the lower casing 212 of the drying tunnel. When the drying tunnel lower shell 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 212 is fixedly connected with the partial folding edge 221, the sealing gasket 23 is squeezed, meanwhile, the buckling surface of the drying tunnel lower shell 212 is enabled to be flush with the surface of the residual folding edge 222, the integrity of the installation surface of the drying tunnel lower shell 212 and the residual folding edge 222 is guaranteed, and the sealing performance is further improved.

In detail, since the drying tunnel body 21 is not regular in shape in general, a misalignment may occur when the drying tunnel lower casing 212 is assembled with the air guide duct 22. According to the utility model, the positioning structures are arranged on the drying tunnel lower shell 212 and the air guide channel 22, when assembling, the approximate position relation between the drying tunnel lower shell 212 and the air guide channel 22 is determined through the positioning structures, and then the next assembling procedure is carried out, so that the situation that the assembly of the drying tunnel lower shell 212 and the air guide channel 22 is not staggered can be ensured, the assembling 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.

When the drying tunnel upper shell 211, the drying tunnel lower shell 212 and the air guide channel 22 are assembled, the sealing body can be firstly installed in any one of the upper sealing groove or the lower sealing groove, and then the drying tunnel upper shell 211, the drying tunnel lower shell 212 and the air guide channel 22 are buckled and connected to extrude the sealing body to achieve the sealing effect.

In some embodiments of the present invention, as shown in fig. 5, the drying assembly 20 further comprises a blower housing; a fan 25 is provided in the fan housing.

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.

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 some embodiments of the present invention, as shown in fig. 5 and 9, a sealing member is disposed between the blower upper shell 26 and the drying tunnel upper shell 211, so that a sealing connection relationship is formed between the blower upper shell 26 and the drying tunnel upper shell 211, thereby ensuring the sealing property between the blower outer shell and the drying tunnel body 21, preventing air leakage, and further improving drying efficiency.
