In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in a specific case to those of ordinary skill in the art.

As shown in fig. 1 to 15, the present invention provides a laundry treating apparatus including a laundry treating drum 100, a window pad 200, and a wind guide passage 300.

The laundry processing drum 100 has a laundry taking and putting opening 105, the laundry taking and putting opening 105 is used for putting or taking laundry into or out of the laundry processing drum 100, and a first channel 104 communicated with the inside of the laundry processing drum 100 is arranged at the laundry taking and putting opening 105.

As a preferred embodiment of the present invention, as shown in fig. 2 to 5, the laundry treating drum 100 includes an outer drum 101 and an inner drum 102 rotatably disposed in the outer drum 101, and the first passage 104 directly communicates with the inside of the inner drum 102.

The window mat 200 comprises an annular body 201 and a second channel 202 formed by the annular body 201 extending outwards, the annular body 201 is covered on the clothing taking and placing opening 105, and the second channel 202 is inserted in the first channel 104. When the door 400 closes the laundry loading and unloading opening 105, the ring-shaped body 201 seals between the laundry loading and unloading opening 105 and the door 400, as shown in fig. 9.

The air guide channel 300 is used for introducing drying hot air into the laundry treatment drum 100, and the air guide channel 300 is disposed at the front side of the laundry treatment drum 100. As shown in fig. 5 and 8, one end of the air guiding channel 300 is inserted into the second channel 202, the other end of the air guiding channel 300 is communicated with a source of drying hot air, and an end of one end of the air guiding channel 300 is at least flush with an end of the second channel 202 on a side close to the laundry loading/unloading opening 105.

In the above embodiment, the first channel 104 provides an installation space for the air guiding channel 300, so that the drying hot air can enter the laundry loading/unloading opening 105 from the front side of the laundry processing drum 100 and then enter the interior of the laundry processing drum 100. Second channel 202 is actually a seal between first channel 104 and air guide channel 300, so that drying hot air can completely enter laundry drum 100 without leaking from the gap between first channel 104 and air guide channel 300.

When the wind guide channel 300 extends into the second channel 202, one end of the wind guide channel 300 is at least flush with one end of the second channel 202 close to the clothes taking and placing opening 105, so that when drying hot wind enters the clothes treatment drum 100 from the wind guide channel 300, the drying hot wind does not directly impact the second channel 202, namely does not directly contact the second channel 202.

Since the window mat 200 is made of a flexible material such as rubber, the second channel 202 is typically integrally formed with the annular body 201, and thus the second channel 202 is also typically made of a rubber-like material. According to the invention, the drying hot air does not directly impact the side wall of the second channel 202, and the second channel 202 can be protected to a certain extent, so that the second channel 202 serving as the sealing structure on the window gasket 200 is not directly impacted by the hot air, and the sealing function of the second channel 202 serving as the sealing structure is prevented from being influenced by aging of the material.

In some embodiments of the present invention, as shown in fig. 10 to 12, at least a section of the outer wall of the air guiding channel 300 inserted into the second channel 202 is contracted along a direction from a side of the second channel 202 away from the clothes access opening 105 to a side of the second channel 202 close to the clothes access opening 105.

As described above, one end of the air guide channel 300 of the present invention is inserted into the second channel 202 and extends into a position flush with at least one end of the second channel 202 close to the door 400. Therefore, in order to facilitate the insertion of the air guiding channel 300 into the second channel 202, the outer wall of at least one section of the pipeline of the air guiding channel 300 extending into the second channel 202 is set to be in a contracted shape, that is, the air guiding channel 300 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 300 should match the cross-sectional shapes of the second channel 202 and the first channel 104, so that the second channel 202 can be tightly fitted between the air guiding channel 300 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 300 extending into the second channel 202 as a shrinking shape, so that the inner wall of the air guiding channel 300 maintains a straight cylindrical structure, thereby achieving the purpose of easy insertion, without reducing the cross-sectional area of the air guiding channel 300, and without reducing the amount of air entering the laundry treating drum 100, thereby increasing the drying rate.

In detail, as shown in fig. 12, a section of the duct of the air guiding channel 300 inserted into the second channel 202 is an air outlet 307, an outer wall of the air outlet 307 is retracted inward by a certain thickness, a shoulder structure is formed on the outer wall of the air outlet 307 and an outer wall of the upper main body of the air guiding channel 300, and when the air outlet 307 is inserted into the second channel 202, the shoulder structure can play a role in limiting.

In another embodiment, the whole air guide channel 300 is set to be contracted along the flow direction of the drying hot air, so that the air guide channel 300 can be inserted into the second channel 202 more conveniently.

The two embodiments can also be combined to form a shoulder structure on the outer wall of the air outlet 307, and the air outlet 307 is a whole contraction structure.

In the above scheme, the longitudinal section of the air guiding channel 300 is in an inverted trapezoid shape along the flow direction of the drying hot air, and the transverse section of the air guiding channel 300 is in a rectangular shape.

In detail, as shown in fig. 10, the air guiding channel 300 includes a first side wall 303, a second side wall 304, a third side wall 305, and a fourth side wall 306 connected in sequence. The first sidewall 303 is disposed opposite to the third sidewall 305, the second sidewall 304 is disposed opposite to the fourth sidewall 306, and the widths of the first sidewall 303 and the third sidewall 305 are smaller than the widths of the second sidewall 304 and the fourth sidewall 306. According to the invention, the second side wall 304 and the fourth side wall 306 with larger widths are set to be in a contraction-shaped structure along the flow direction of the drying hot air, and the first side wall 303 and the third side wall 305 with smaller widths are set to be in an approximately parallel-shaped structure along the flow direction of the drying hot air, so that the air guide channel 300 is integrally in a thin wedge-shaped structure, and the air guide channel 300 is convenient to insert into a second air duct.

In some embodiments of the present invention, as shown in fig. 5 and 8, an end of the second channel 202 away from the clothing access opening 105 is at least partially provided with an outward folded portion 203, and an end of the first channel 104 away from the clothing access opening 105 is in interference connection with the folded portion 203.

In detail, the laundry treating drum 100 includes an outer drum 101 and an inner drum 102, the outer drum 101 has an open structure at a front end, and an outer drum front structure 103 is disposed at the open position to close the open position. The first channel 104 is disposed on the outer barrel front structure 103. In a preferred embodiment, the first channel 104 is formed on the outer cylindrical front structure 103.

That is, a cover is disposed on the outer cylinder front structure 103, and an inner wall of the cover and an outer wall of the outer cylinder front structure 103 together form the first passage 104.

Since the air guide passage 300 of the present invention needs to be inserted at least to the end of the second passage 202 close to the clothes inlet 105, in other words, the air guide passage 300 of the present invention needs to be inserted into the second passage 202 for a long length. Further, since the assembly sequence of the air guide duct 300 is the latter and the assembly sequence of the second duct 202 is the former, the second duct 202 and the annular body 201, which have been assembled, are likely to be displaced from their original positions during the insertion of the air guide duct 300. In summary, in order to avoid the second channel 202 and the annular body 201 from being displaced during the assembly and insertion process, the present invention at least partially provides an outward folded part 203 on the side of the second channel 202 away from the clothes access opening 105, i.e. provides a folded part 203 at least at the position matching with the casing, so that the end of the casing away from the clothes access opening 105 interferes with the folded part 203. Thus, when the air guide duct 300 is fitted into and inserted into the second duct 202, the flap 203 can grasp the end of the cover and is not displaced with the insertion of the air guide duct 300.

In some embodiments of the invention, the flap 203 comprises a first flap 205 and a second flap 206 connected to each other; the side wall of the second channel 202, the first flange 205 and the second flange 206 together form an embedded part 204 with a groove-shaped structure; an end of the first channel 104 remote from the laundry access opening 105 is inserted into the insertion portion 204.

In detail, the section of the turning part 203 is in an L-shape structure, so that the sidewall of the second channel 202 and the turning part 203 together form an embedded part 204 in a groove structure, which is in an inverted U-shape structure. When the window gasket 200 is assembled, the end of the housing is inserted into the insertion portion 204 through the opening of the insertion portion 204. In other words, the groove-shaped structure of the insertion portion 204 tightly wraps the upper end of the casing forming the first channel 104, so as to prevent the second channel 202 from being displaced by the wind guide channel 300, thereby ensuring that the joint between the wind guide channel 300 and the first channel 104 has a good sealing effect all the time.

In a specific embodiment, the first flange 205 extends from the end of the second channel 202 along the radial direction thereof, and the second flange 206 extends from the end of the first flange 205 along the axial direction of the second channel 202 to the side close to the clothing access opening 105.

Further, the inner side surface of the second flange 206 may be provided with an inclined structure to reduce the opening size of the insertion portion 204. In general, the folded portion 203 is integrally formed with the second channel 202, and is also made of rubber, and when the opening of the insertion portion 204 is reduced, the opening of the insertion portion 204 is fastened to the upper end of the housing like a binding, thereby further preventing displacement.

Furthermore, an avoiding portion matched with the folded portion 203 is arranged on the outer side of the housing, and when the groove-shaped structure of the embedding portion 204 tightly wraps the upper end of the housing forming the first channel 104, the end portion of the second folded edge 206 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. 3 to 8, one end of the wind guiding channel 300 is connected to the second channel 202 in an interference fit manner.

In detail, since the end of the second channel 202 is provided with the folded portion 203 capable of wrapping the end of the casing constituting the first channel 104, the air guide channel 300 cannot be directly connected to the first channel 104, and the fixation of the air guide channel 300 is affected.

In the invention, the assembly relationship between the air guide channel 300 and the second channel 202 is set to be interference fit, that is, a certain external force is required to insert the air guide channel 300 into the second channel 202. That is, when air guide duct 300 is assembled, an interference space is formed between air guide duct 300 and second duct 202, air guide duct 300 is pressed against second duct 202 by external force, and air guide duct 300 is fixed by making full use of the elasticity of second duct 202.

In the above solution, the air guide channel 300 is inserted into the end of the second channel 202, so that the drying hot air can be prevented from directly impacting the second channel 202 to cause the second channel 202 to age, and the purpose of fixing the second channel 202 can be achieved by using the elasticity of the second channel 202. It can be seen that the above solutions of the present aspect complement each other.

In a further aspect, as shown in fig. 1 and fig. 2, a first fixing structure 106 is disposed at a front side of the laundry treatment drum 100, and a second fixing structure 302 is disposed at an outer portion of the air guiding channel 300; a fixed connector is disposed between the first fixing structure 106 and the second fixing structure 302.

In detail, the air guiding channel 300 is a hollow pipe structure surrounded by a first side wall 303, a second side wall 304, a third side wall 305 and a fourth side wall 306, and a second fixing structure 302, for example, a lug with a through hole, is respectively disposed outside the first side wall 303 and the third side wall 305. Preferably, the second fixing structure 302 is disposed at a middle position of the first and third sidewalls 303 and 305 in a flowing direction of the drying hot wind. Meanwhile, a first fixing structure 106, for example, a boss with a screw hole, is provided at the front side of the laundry treating drum 100, i.e., at a position on the outer drum front structure 103 that matches the position of the second fixing structure 302.

When the air guide channel 300 is assembled, the air guide channel 300 is firstly inserted into the second channel 202, then the positions of the second fixing structure 302 and the first fixing structure 106 are matched in place, and then the first fixing structure 106 and the second fixing structure 302 are fastened by fastening screws, so that the air guide channel 300 is further fixed.

It should be noted that the above-mentioned protruding lugs and protruding columns are only one embodiment capable of implementing the technical solution of the present invention, and any other technical solutions capable of implementing the fixed relative fixed connection between the air guide channel 300 and the laundry processing drum 100 are within the scope of the present invention.

Alternatively, the number of the first fixing structures 106 and the second fixing structures 302 may be multiple, for example, two, and the first fixing structures and the second fixing structures are disposed on the left and right sides of the air guide channel 300, which is beneficial to improving the fixing effect of the air guide channel 300 and the outer cylinder front structure 103.

In some embodiments of the present invention, as shown in fig. 6 to 8, a reinforcing portion for increasing strength is provided on at least a section of an inner wall of the wind guide channel 300 inserted into the second channel 202.

In detail, as mentioned above, the air guiding channel 300 extends at least to the end of the second channel 202, and the air guiding channel 300 is subjected to a high frequency of cold and hot impacts at the air outlet 307, and in addition, the air guiding channel 300 is generally made of a rigid plastic material, so that in order to prevent the material of the air guiding channel 300 from being stretched or shrunk and deformed under the action of cold and hot frequent impacts, and further influence the assembly strength and the air volume, the present invention provides a reinforcing part for reinforcing the strength of the air guiding channel 300 on the inner wall of the air outlet 307 of the air guiding channel 300.

In a specific embodiment, a reinforcing rib plate 301 is disposed between the second side wall 304 and the fourth side wall 306 of the air guide channel 300, which are disposed opposite to each other, and the reinforcing rib plate 301 is generally disposed at a middle position of the second side wall 304 and the fourth side wall 306, and deformation is likely to occur at the middle position due to the larger width of the second side wall 304 and the fourth side wall 306, that is, the larger span of the second side wall 304 and the fourth side wall 306. Placing stiffener plate 301 in an intermediate position may serve to support second sidewall 304 and fourth sidewall 306, as shown in fig. 10.

It should be noted that the rib plates 301 are also easily impacted by the cold and hot air, and therefore, the rib plates 301 should have a certain strength at least greater than the strength of the side walls of the air guiding channel 300.

In some embodiments of the present invention, as shown in fig. 12, an end of the air guiding channel 300 close to a side wall of the laundry processing drum 100 has a projection on a side wall far from the laundry processing drum 100.

In other words, the length of the end of the air guiding channel 300 on the side away from the laundry treatment drum 100 is greater than the length of the end of the air guiding channel 300 on the side close to the laundry treatment drum 100.

According to the invention, the positioning structures 1033 are arranged on the drying tunnel lower shell 502 and the air guide channel 300, when assembling, the approximate position relation between the drying tunnel lower shell 502 and the air guide channel 300 is determined through the positioning structures 1033, and then the next assembling procedure is carried out, so that the situation that the assembly of the drying tunnel lower shell 502 and the air guide channel 300 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 500 and the air guide channel 300, 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 501, the drying tunnel lower shell 502 and the air guide channel 300 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 501, the drying tunnel lower shell 502 and the air guide channel 300 are buckled and connected to extrude the sealing body to achieve a sealing effect.

In the second scheme, an upper sealing groove is formed in the buckling surface of the drying tunnel upper shell 501 along the contour line; the buckling surface of the lower drying tunnel shell 502 and the surface of the residual folded edge 309 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 502 and the surface of the residual folding edge 309.

The difference between this scheme and the first scheme is that only the upper sealing groove is arranged on the fastening surface of the drying tunnel upper shell 501, and the sealing effect is realized by jointly extruding the sealing body by using the fastening surface of the drying tunnel lower shell 502 and the surface of the residual folded edge 309.

In the third scheme, a lower sealing groove is formed in the surface of the residual folding edge 309 and the buckling surface of the lower drying tunnel shell 502 along the contour line; the surface of the buckling surface of the drying tunnel upper shell 501 is of a planar 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 501 jointly compress the sealing ring.

The difference between this scheme and the first scheme is that only the fastening surface of the lower drying tunnel shell 502 and the surface of the residual folded edge 309 are provided with lower sealing grooves, and the sealing body is extruded by the fastening surface of the upper drying tunnel shell 501 to realize the sealing effect.

Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present invention.
