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 a window mat body 201 and a second channel 202 formed by the window mat body 201 extending outwards, the window mat body 201 is coated on the clothes 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 window gasket 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 may be disposed at a front side of the laundry treatment drum 100. The air guiding channel 300 comprises a body having a hollow pipe, one end of the hollow pipe constitutes an air inlet, and the other end constitutes an air outlet 307.

The body comprises a first side wall 303, a second side wall 304, a third side wall 305 and a fourth side wall 306, wherein the first side wall 303, the second side wall 304, the third side wall 305 and the fourth side wall 306 are sequentially connected end to form the hollow pipeline in an enclosing manner. 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. In the air outlet 307, the distance from the middle of the second side wall 304 and the fourth side wall 306 to the air inlet is smaller than the distance from the end of the second side wall 304 and the fourth side wall 306 to the air inlet.

In detail, at the air outlet 307, the middle portions of the second side wall 304 and the fourth side wall 306 are designed to have a structure retracting towards the air inlet direction, so as to avoid mechanical interference between the air guide channel 300 and the window gasket body 201 after installation is completed, so that the air guide channel 300 of the present invention can be inserted into the second channel 202 of the window gasket 200 and reach the position of the window gasket body 201, so that 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 a sealing structure on the window gasket 200 cannot be directly impacted by the hot air, and the sealing function of the second channel 202 serving as a sealing structure is prevented from being influenced by aging of the material of the second channel 202.

Specifically, as shown in fig. 5 and 8, one end of the air guiding channel 300 is inserted into the second channel 202, an air inlet of the hollow pipeline is communicated with a source of drying hot air, and an end of one end of the hollow pipeline is at least flush with an end of the second channel 202 on a side close to the clothes taking and placing 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. The second channel 202 substantially serves as a sealing member between the first channel 104 and the wind guide channel 300, so that the drying hot wind can completely enter the laundry treating drum 100 without leaking from a gap between the first channel 104 and the wind guide channel 300.

In a preferred embodiment, the second sidewall 304 and the fourth sidewall 306 have a circular arc structure at the air outlet 307.

Since the structure of the window mat body 201 is generally an annular structure, in order to make the structure of the air outlet 307 of the air guiding channel 300 match the structure of the opening of the window mat body 201 better, the structures of the second side wall 304 and the fourth side wall 306 at the air outlet 307 are designed to be arc-shaped structures. Moreover, this structure can prevent the user from getting the laundry through the laundry taking and putting opening 105.

In some embodiments of the present invention, the first sidewall 303 and the third sidewall 305 are provided with a fixing structure for fixedly connecting with the front side of the laundry treating apparatus.

In a specific embodiment, 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 outside the air guide channel 300; a fixed connection is provided 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 on the front side of the laundry treating drum 100, i.e., on the outer drum front plate 103 at a position matching 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 barrel front plate 103.

In some embodiments of the present invention, at the air inlet, the first side wall 303, the second side wall 304, the third side wall 305 and the fourth side wall 306 are provided with folded edges folded outwards; the folded edge of the fourth side wall 306 is used for being in sealing connection with the surface of the air outlet of the drying tunnel body of the clothes treatment device, and the folded edges of the first side wall 303, the second side wall 304 and the third side wall 305 are used for being in sealing connection with the end face of the air outlet of the drying tunnel body of the clothes treatment device.

In detail, the clothes treatment equipment further comprises a drying tunnel body, and a heating device is arranged in the drying tunnel body and used for heating air. The air outlet of the drying tunnel body is connected with the air guide channel 300, and the air is heated in the drying tunnel body, passes through the air guide channel 300 and then enters the clothes treatment cylinder 100.

Specifically, the drying tunnel body includes drying tunnel epitheca and drying tunnel inferior valve of mutual lock, the outer wall of drying tunnel inferior valve is planar structure in its air outlet department, the drying tunnel epitheca is the curved surface structure in its air outlet department. The end of the air inlet of the air guide channel 300 is provided with a folded edge which is turned outwards. The outer wall surface of the lower drying tunnel shell is hermetically connected with part of the folded edge surface of the air guide channel 300, and the end part of the upper drying tunnel shell is hermetically connected with the residual folded edge end surface of the air guide channel 300.

In detail, as shown in fig. 4 and 6, taking an example that the drying tunnel body is disposed above the laundry treating drum 100 of the laundry treating apparatus, the curved surface structure of the drying tunnel upper shell is formed by bending a flat surface downwards. The outer wall surface of the lower drying tunnel shell is of a plane structure at the air outlet, in other words, the side wall of the lower drying tunnel shell is not bent downwards. That is, the air outlet of the drying tunnel body is not provided with an elbow structure.

When the air guide channel 300 is connected with the front side of the laundry treating drum 100, the fourth sidewall 306 is close to the laundry treating drum 100, and the second sidewall 304 is far from the laundry treating drum 100.

The first side wall 303, the second side wall 304, the third side wall 305 and the fourth side wall 306 are all folded outwards to form a folded edge, and therefore, the corresponding folded edge of the fourth side wall 306 is used for being connected with the air outlet surface of the drying tunnel body of the clothes treatment device in a sealing manner, namely, connected with the drying tunnel lower shell. The corresponding folds of the first, third and second side walls 303, 305, 304 are used for sealing connection with the outlet end face of the drying tunnel body of the clothes treatment apparatus, i.e. the drying tunnel upper shell.

When the drying tunnel body is assembled with the air guide channel 300, the lower drying tunnel shell is firstly connected with the folded edge of the fourth side wall 306 in a sealing manner, then the upper drying tunnel shell is connected with the folded edge on the other side wall in a sealing manner, and then the upper drying tunnel shell is connected with the lower drying tunnel shell in a buckling manner.

In other words, the structure of the drying tunnel body and the connection mode between the drying tunnel body and the air guide channel 300 are substantially that the outer wall surface of the lower drying tunnel shell is in surface sealing connection with the partial folded edge of the air guide channel 300, and the upper drying tunnel shell is in buckling connection with the lower drying tunnel shell and the residual folded edge of the air guide channel 300.

In addition, the sealing performance between the drying tunnel body and the air guide passage 300 can be improved by the connection structure.

Further, the distance between the plane where the folded edge of the fourth side wall 306 is located and the air outlet is smaller than the distance between the plane where the folded edge of the first side wall 303, the second side wall 304, and the third side wall 305 is located and the air outlet.

Specifically, the surface of the partial folded edge formed by folding the fourth side wall 306 is lower than the surface of the remaining folded edge formed by folding the remaining side walls, so as to form an installation space for installing the air outlet of the lower shell of the drying tunnel. The lower drying tunnel shell comprises a bottom wall and side walls, and after the bottom wall of the lower drying tunnel shell is connected with the folded edge of the second side wall 304, the upper edge of the side wall at the air outlet of the lower drying tunnel shell is flush with the surfaces of the folded edges formed by folding the first side wall 303, the third side wall 305 and the second side wall 304. In other words, the fastening surface of the lower drying tunnel shell and the upper drying tunnel shell is kept flush with the surface of the residual folded edge.

Above-mentioned scheme can increase the space of drying tunnel body and air guide channel 300 switching department, and the air after avoiding the heating forms the vortex here, influences air inlet efficiency.

Further, a positioning structure is disposed on a folded edge of the second side wall 304.

In detail, the drying tunnel upper shell is provided with a first positioning structure at the air outlet, and a second positioning structure is arranged on the remaining folded edge of the air guide channel 300 and connected with the second positioning structure.

In general, since the shape of the drying tunnel body is not regular, a misalignment may occur when the lower drying tunnel shell is assembled with the air guide duct 300. According to the invention, the positioning structures are arranged on the lower drying tunnel shell and the air guide channel 300, when the clothes drying device is assembled, the approximate position relation between the lower drying tunnel shell and the air guide channel 300 is determined through the positioning structures, and then the next assembly process is carried out, so that the condition that the lower drying tunnel shell and the air guide channel 300 are assembled without dislocation 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 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.

In some embodiments of the present invention, a reinforcing structure for reinforcing the strength of the sidewall of the body is disposed on the inner wall of the end of the body close to the air outlet 307.

In detail, as shown in fig. 6 to 8, the reinforcing structure for reinforcing the strength of the side wall is disposed at the air outlet 307 of the air guiding duct 300, so that the side wall of the air guiding duct 300 at the air outlet 307 can bear a large thermal load and a high thermal shock frequency. Therefore, when the air guide channel 300 extends into the second channel 202, one end of the air guide channel 300 is at least flush with one end of the second channel 202 close to the clothes taking and placing opening 105, the air guide channel 300 replaces a sealing piece to directly bear heat load, and the door sealing ring is not required to be exposed in a high-temperature hot air environment for a long time. In this way, when the drying hot air enters the interior of the laundry processing drum 100 from the air guiding channel 300, the drying hot air does not directly impact the second channel 202, i.e. does not directly contact the second channel 202.

Since the window mat 200 is made of a flexible material such as rubber, and the second channel 202 is generally integrally formed with the window mat body 201, the second channel 202 is also generally 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 a further aspect, the reinforcing structure is disposed on the second sidewall 304 and the fourth sidewall 306.

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 arranged between the second side wall 304 and the fourth side wall 306 of the air guiding channel 300, which are arranged oppositely, and the reinforcing rib plate 301 is generally arranged at the 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 subjected to frequent impact of cold and hot air, and therefore, the rib plates 301 should have a certain strength at least greater than that of the side wall of the air guiding channel 300.

In some embodiments of the present invention, in the air outlet 307, the distance from the middle of the second side wall 304 and the fourth side wall 306 to the air inlet is smaller than the distance from the end of the second side wall 304 and the fourth side wall 306 to the air inlet.

In detail, as described above, when the air guiding channel 300 of the present invention is assembled, at least one end of the air inlet thereof needs to be inserted into a position flush with the end of the second channel 202 of the window mat 200 close to the clothes inlet 105, and both the clothes inlet 105 and the window mat body 201 are annular structures. Therefore, in order to match the structure of the air outlet 307 of the air guiding channel 300 of the present invention with the structure of the clothes pick-and-place opening 105 and the window pad body 201, the distance from the middle of the second side wall 304 and the fourth side wall 306 to the air inlet is smaller than the distance from the end of the second side wall 304 and the fourth side wall 306 to the air inlet. That is, one end of the air outlet 307 of the air guiding channel 300 is set to be an arch structure, so that the drying hot air can directly enter the laundry processing drum 100 from the air guiding channel 300. Moreover, the air outlet 307 of the air guiding channel 300 can avoid the thermal shock with high frequency, thereby preventing the material from stretching, contracting and deforming to influence the air volume.

In some embodiments of the present invention, the distance from the end surface of the air outlet 307 of the second sidewall 304 to the air inlet is greater than the distance from the end surface of the air outlet 307 of the fourth sidewall 306 to the air inlet.

In other words, as shown in fig. 12, after the wind guiding channel 300 is assembled, the length of the side of the wind inlet end of the wind guiding channel 300 far away from the laundry treatment drum 100 is greater than the length of the side of the wind inlet end of the wind guiding channel 300 near the laundry treatment drum 100.

In detail, in order to reduce the heat loss of the drying hot air, the drying hot air should be guided into the interior of the laundry treatment drum 100 as much as possible, and therefore, in the prior art, an adapter tube is disposed at the air outlet 307 of the air guiding channel 300, the adapter tube is an elbow-shaped structure, one end of the adapter tube is connected with the air guiding channel 300, and the other end of the adapter tube faces the interior of the laundry treatment drum 100, so that the drying hot air can directly enter the laundry treatment drum 100 without contacting the door 400, thereby reducing the heat loss and further improving the drying efficiency.

However, although the above-mentioned scheme of increasing the adapter tube has solved the hot-blast calorific loss's of stoving problem, also increased clothes treatment facility's assembly structure simultaneously, reduced assembly efficiency, still increased clothes treatment facility's cost.

Therefore, the present invention abandons the structure of arranging an adapter tube in the prior art, and inserts the air outlet 307 of the air guiding channel 300 directly into the position of the window pad body 201, and simultaneously sets the length of one end of the air guiding channel 300 away from the laundry treatment drum 100 to be greater than the length of one end of the air guiding channel 300 close to the laundry treatment drum 100, that is, the length of the second side wall 304 is greater than the length of the fourth side wall 306. The drying hot air is guided to be naturally guided into the interior of the laundry treating drum 100 by the structure formed between the side wall having the longer length and the side wall having the shorter length, so as to increase the effective intake air, as shown in fig. 4 to 8.

The scheme of the invention simplifies the assembly structure of the clothes treatment equipment and improves the assembly efficiency.

In a further aspect, as shown in fig. 6 to 8, the laundry treating apparatus further includes a door 400 for opening and closing the laundry loading and unloading opening 105; the end of one end of the air guide channel 300 is far away from the laundry treatment drum 100 and contacts with the door 400.

In detail, the door 400 has an inclined plane, when the door 400 is closed, one side of the air guide channel 300 far away from the laundry treatment drum 100 contacts with the door 400, and the side wall of the air guide channel 300 with a longer length and the inclined plane of the door 400 actually form an air guide part with a lambda-shaped structure for guiding the drying hot air into the laundry treatment drum 100.

The clothes treatment equipment is a washing and drying integrated machine, can be a floor type drum-type washing and drying integrated machine, and can also be a wall-mounted washing and drying integrated machine.

The laundry treating apparatus further includes a fan, a heater, a condenser, and the like, which can implement a drying function.

In some implementations of the invention, at least a section of the outer wall of the body near the outlet 307 is tapered along a direction from the inlet to the outlet 307.

In other words, as shown in fig. 10 to 12, the cross-sectional area of the hollow pipeline gradually decreases along the direction from the air inlet to the air outlet 307.

As described above, after the air guide channel 300 is assembled, one end of the air guide channel 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 attached 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 wall 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 guiding channel 300 is set to be contracted along the flow direction of the drying hot air, so that the air guiding 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 second side wall 304 and the fourth side wall 306 with larger widths are set to be in a contracted 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 structure along the flow direction of the drying hot air, so that the air guide channel 300 is in a thin wedge-shaped structure as a whole, and the air guide channel 300 is convenient to be inserted into the 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 a structure in which a 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 disposed 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 form the first passage 104.

Since the air guide passage 300 of the present invention needs to be inserted into at least the end of the second passage 202 close to the clothes loading/unloading opening 105, in other words, the air guide passage 300 of the present invention needs to be inserted into the second passage 202 to a long length. Further, since the air guide duct 300 is assembled in the latter order and the second duct 202 is assembled in the former order, the second duct 202 and the window mat body 201 which have been assembled are likely to be displaced from their original positions during the process of inserting the air guide duct 300. In summary, in order to avoid the second channel 202 and the window gasket body 201 from being displaced during the assembling and inserting process, the present invention at least partially provides an outward folded portion 203 on the side of the second channel 202 away from the clothing access opening 105, i.e. provides the folded portion 203 at least at the position matching with the casing, so that the end of the casing away from the clothing access opening 105 is abutted against the folded portion 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 present invention, the fold-over 203 comprises a first fold 205 and a second fold 206 connected to each other; the sidewall of the second channel 202, the first folded part 205 and the second folded part 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 embedding portion 204 tightly wraps the upper end of the housing forming the first channel 104, so as to prevent the second channel 202 from being displaced by the air guiding channel 300, and further ensure that the joint between the air guiding channel 300 and the first channel 104 has a good sealing effect all the time.

In a specific embodiment, the first folded part 205 is extended from the end of the second channel 202 along the radial direction thereof, and the second folded part 206 is extended from the end of the first folded part 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 folded portion 206 may be provided with an inclined structure to reduce the size of the opening of the embedding 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 portion 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 the air guide passage 300 is assembled, an interference space is formed between the air guide passage 300 and the second passage 202, the air guide passage 300 is pressed against the second passage 202 by an external force, and the elasticity of the second passage 202 is fully utilized to fix the air guide passage 300.

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.

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 invention as defined by the appended claims.
