In a preferred embodiment, the first mounting structure 227 may be a lug with a through hole protruding from a side wall of the air guiding channel 22, and the second mounting structure 106 may be a boss with a screw hole protruding from a front side of the laundry treatment drum 10. When the air guide channel 22 is assembled, two ends of the air guide channel 22 are fixed, and then the convex lugs and the convex columns are fastened and connected through screws.

In some embodiments of the present invention, a mounting hole for installing a temperature sensor is formed on a side wall of the air guiding channel 22 at a position between the air inlet and the first mounting structure 227. The temperature sensor is inserted into the air guide channel 22 through the mounting hole to obtain the temperature of the air in the air guide channel 22, so that the clothes processing equipment can conveniently control parameters such as the power of the heating device 24 and the fan.

In some embodiments of the present invention, as shown in fig. 3 and 4, the drying tunnel body 21 includes an upper drying tunnel shell 211 and a lower drying tunnel shell 212, which are fastened to each other, the upper drying tunnel shell 211 and the lower drying tunnel shell 212 together enclose an airflow channel having an air inlet and an air outlet, and the heating device 24 is disposed in the airflow channel. The outer wall of the lower drying tunnel shell 212 is of a plane structure at the air outlet, and the upper drying tunnel shell 211 is of a curved structure at the air outlet. The end of the air inlet of the air guide channel 22 is provided with a folded edge which is turned outwards. The outer wall surface of the drying tunnel lower shell 212 is hermetically connected with the surface of a part of the folding edge 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 remaining folding edge 222 of the air guide channel 22.

In detail, as shown in fig. 4, 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 upper shell 211 is formed by bending a flat surface downward. The outer wall surface of the lower drying tunnel shell 212 is a plane structure at the air outlet, in other words, the side wall of the lower drying tunnel shell 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 portion of the flap 221 is used to connect with the outer wall of the lower housing 212 of the drying tunnel and the other portion of the flap 221 is used to connect with the end of the upper housing 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 folded edges, and therefore the folded edges corresponding to the second side wall are the partial folded edges 221 and are connected with the outer wall of the drying tunnel lower 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 end surface of 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.

In the above scheme, the drying tunnel body 21 is provided with the drying tunnel upper shell 211 and the drying tunnel lower shell 212 which are in split structures, and the drying tunnel 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 air guide channel 22 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 assembly 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 to 8, the plane of the surface of the partial folded edge 221 formed by folding the second side wall is lower than the plane of 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 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.

In some embodiments of the present invention, the sealing connection between the outer wall surface of the lower drying tunnel 212 and the partial folded edge 221 of the air guiding passage 22 includes the following three schemes.

In the second scheme, an upper sealing groove is formed in the buckling surface of the drying tunnel upper shell 211 along the contour line; the fastening surface of the lower drying tunnel shell 212 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 drying tunnel lower shell 212 and the surface of the residual folding edge 222.

The difference between this scheme and the first scheme is that only the fastening surface of the drying tunnel upper shell 211 is provided with an upper sealing groove, and the sealing effect is realized by jointly extruding the sealing body by using the fastening surface of the drying tunnel lower shell 212 and the surface of the residual folded edge 222.

In the third scheme, a lower sealing groove is formed on the surface of the residual folding edge 222 and the buckling surface of the lower drying tunnel shell 212 along the contour line; the surface of the buckling surface of the drying tunnel upper shell 211 is of a plane structure; a sealing ring is arranged in the lower sealing groove, and the lower sealing groove and the buckling surface of the drying tunnel upper shell 211 are jointly pressed tightly by the sealing ring.

The difference between this scheme and the first scheme is that only the fastening surface of the lower drying tunnel shell 212 and the surface of the residual folded edge 222 are provided with lower sealing grooves, and the sealing body is extruded by the fastening surface of the upper drying tunnel shell 211 to realize the sealing effect.

As described above, the air guide passage 22 is used for introducing dry hot air into the laundry treatment drum 10, and the air guide passage 22 is disposed at the front side of the laundry treatment drum 10.

Therefore, in some embodiments of the present invention, as shown in fig. 9, one end of the air guiding channel 22 is inserted into the second channel 312, the other end of the air guiding channel 22 is communicated with the source of the drying hot wind, and an end of one end of the air guiding channel 22 is at least flush with an end of the second channel 312 on a side close to the laundry loading and unloading opening 105.

In the above embodiment, the first channel 104 provides an installation space for the air guiding channel 22, so that the drying hot air can enter the laundry loading/unloading opening 105 from the front side of the laundry treatment drum 10 and then enter the interior of the laundry treatment drum 10. Second channel 312 is actually a seal between first channel 104 and air guide channel 22, so that drying hot air can completely enter laundry drum 10 without leaking from the gap between first channel 104 and air guide channel 22.

When the wind guide channel 22 extends into the second channel 312, one end of the wind guide channel 22 is at least flush with one end of the second channel 312 close to the clothes taking and placing opening 105, so that when drying hot wind enters the inside of the clothes processing drum 10 from the wind guide channel 22, the drying hot wind does not directly impact the second channel 312, namely, does not directly contact the second channel 312.

Since the window mat 30 is made of a flexible material such as rubber, and the second channel 312 is generally integrally formed with the window mat body 311, the second channel 312 is also generally made of a rubber material. According to the utility model, the drying hot air does not directly impact the side wall of the second channel 312, and the second channel 312 can be protected to a certain extent, so that the second channel 312 serving as a sealing structure on the window gasket 30 is not directly impacted by the hot air, and the sealing function of the second channel 312 serving as a sealing structure is prevented from being influenced by aging of the material.

In some embodiments of the present invention, as shown in fig. 9, at least a section of the outer wall of the air guiding channel 22 inserted into the second channel 312 is contracted along a direction from the side of the second channel 312 far from the clothes placing opening 105 to a side of the second channel 312 close to the clothes placing opening 105.

As described above, one end of the air guide duct 22 of the present invention is inserted into the second duct 312, and extends into a position flush with at least one end of the second duct 312 close to the door body. Therefore, in order to insert the air guiding channel 22 into the second channel 312, the outer wall of a section of the air guiding channel 22 extending into the second channel 312 is set to be contracted, that is, the air guiding channel 22 is in an inverted bell mouth shape along the flow direction of the drying hot air.

It should be noted that the cross-sectional shape of the air guiding channel 22 should match the cross-sectional shapes of the second channel 312 and the first channel 104, so that the second channel 312 can be tightly fitted between the air guiding channel 22 and the first channel 104.

In one embodiment, the present invention only defines the outer wall of at least one section of the air guiding channel 22 extending into the second channel 312 as a shrinking shape, so that the inner wall of the air guiding channel 22 maintains a straight cylindrical structure, thereby achieving the purpose of easy insertion, without reducing the cross-sectional area of the air guiding channel 22, and without reducing the amount of air entering the laundry treating drum 10, thereby increasing the drying rate.

In detail, as shown in fig. 9, a section of the duct of the air guiding channel 22 inserted into the second channel 312 is an air outlet, an outer wall of the air outlet is retracted inward by a certain wall thickness, a shoulder structure is formed on the outer wall of the air outlet and an outer wall of the upper main body of the air guiding channel 22, and when the air outlet is inserted into the second channel 312, the shoulder structure can play a role in limiting.

In another embodiment, the air guiding channel 22 is integrally set to be contracted along the flow direction of the drying hot air, so that the air guiding channel 22 is more conveniently inserted into the second channel 312.

The two embodiments can also be combined for use, so that a shoulder structure is formed on the outer wall of the air outlet, and the air outlet is integrally in a shrinkage structure.

In the above-mentioned scheme, the longitudinal section of the air guiding channel 22 is in an inverted trapezoid shape along the flow direction of the drying hot air, and the transverse section of the air guiding channel 22 is in a rectangular shape.

In some embodiments of the present invention, as shown in fig. 5 and 9, an end of the second channel 312 away from the clothing access opening 105 is at least partially provided with an outward folded portion, and an end of the first channel 104 away from the clothing access opening 105 is in interference connection with the folded portion.

In detail, the laundry treating drum 10 includes an outer drum and an inner drum 102, the outer drum has a structure in which the front end has an opening, and a front plate 103 of the outer drum is provided at the opening to close the opening. The first channel 104 is arranged on the front plate 103 of the outer cylinder. In a preferred embodiment, the first channel 104 is formed on the outer cylinder front plate 103.

That is, a cover is provided on the outer cylinder front plate 103, and an inner wall of the cover and an outer wall of the outer cylinder front plate 103 together constitute the first passage 104.

Since the air guide passage 22 of the present invention needs to be inserted at least to the end of the second passage 312 near the clothes inlet 105, in other words, the air guide passage 22 of the present invention needs to be inserted into the second passage 312 for a long length. Further, since the air guide duct 22 is assembled in the subsequent order and the second duct 312 is assembled in the previous order, the second duct 312 and the window pad body 311, which have been assembled, are likely to be displaced from their original positions during the process of inserting the air guide duct 22. In summary, in order to avoid the second channel 312 and the window pad body 311 from shifting during the assembling and inserting process, the present invention at least partially provides an outward folded portion on the side of the second channel 312 away from the clothing access opening 105, that is, provides a folded portion at a position at least matching with the casing, so that the end of the casing away from the clothing access opening 105 is abutted against the folded portion. Thus, when the air guide duct 22 is fitted into and inserted into the second duct 312, the folded portion can grasp the end of the cover, and the air guide duct 22 is not displaced.

In some embodiments of the utility model, the flap comprises a first flap 315 and a second flap 316 connected to each other; the sidewall of the second channel 312, the first folded part 315 and the second folded part 316 together form an embedded part 314 with a groove-shaped structure; an end of the first passage 104 remote from the laundry access opening 105 is inserted into the insertion portion 314.

In detail, the turning portion has a reverse-L-shaped cross section, so that the sidewall of the second channel 312 and the turning portion together form a recessed insertion portion 314 having an inverted-U-shaped structure. When the window gasket 30 is assembled, the end of the housing is inserted into the insertion portion 314 through the opening of the insertion portion 314. In other words, the groove-shaped structure of the embedding portion 314 tightly wraps the upper end of the casing forming the first channel 104 to prevent the second channel 312 from being displaced by the wind guiding channel 22, so as to ensure that the joint of the wind guiding channel 22 and the first channel 104 has a good sealing effect all the time.

In a specific embodiment, the first folded part 315 extends from the end of the second channel 312 outward along the radial direction thereof, and the second folded part 316 extends from the end of the first folded part 315 along the axial direction of the second channel 312 to a side close to the clothing access opening 105.

Further, the inner side surface of the second folded portion 316 may be provided with an inclined structure to reduce the size of the opening of the insertion portion 314. In general, the folded portion is integrally formed with the second channel 312, and is also made of rubber, so that when the opening of the insertion portion 314 is reduced, the opening of the insertion portion 314 is fastened to the upper end of the housing like a binding, thereby further preventing displacement.

Furthermore, the outside of the housing is provided with an avoiding portion matched with the folded portion, when the groove-shaped structure of the embedding portion 314 tightly wraps the upper end of the housing forming the first channel 104, the end portion of the second folded portion 316 can be located in the avoiding portion, so that the fixing effect is better.

In some embodiments of the present invention, as shown in fig. 5 and 9, one end of the wind guiding channel 22 is connected to the second channel 312 in an interference fit manner.

In detail, since the end of the second channel 312 is provided with the folded portion capable of wrapping the end of the casing constituting the first channel 104, the air guide channel 22 cannot be directly connected to the first channel 104, and the fixation of the air guide channel 22 is affected.

The present invention sets the assembling relationship between the air guiding channel 22 and the second channel 312 as interference fit, that is, a certain external force is required to insert the air guiding channel 22 into the second channel 312. That is, when the air guide passage 22 is assembled, an interference space is formed between the air guide passage 22 and the second passage 312, the air guide passage 22 is pressed against the second passage 312 by an external force, and the elasticity of the second passage 312 is fully utilized to fix the air guide passage 22.

In the above solution, the air guide channel 22 is inserted into the end of the second channel 312, so that the drying hot air can be prevented from directly impacting the second channel 312 to cause the second channel 312 to age, and the purpose of fixing the second channel 312 can be achieved by using the elasticity of the second channel 312. It can be seen that the above solutions of the present aspect complement each other.

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.
