Description

TECHNICAL FIELD

[0001] The present application relates to the field of clothes processing devices, in particular to a fixed structure of a stacked clothes processing device and a stacked clothes processing device. BACKGROUND

[0002] In modern life, washing machines have become a necessary household appliance. Some families further purchase clothes dryers due to the need for drying clothes after washing, or have multiple washing machines to meet the needs of adults and children to wash clothes separately.

[0003] The above needs will lead to an excessive number of household appliances and space occupation problems. Users usually choose to stack two appliances vertically, but the connection between the two devices is loose and unstable, which has safety hazards.

[0004] To solve the above problems, the prior art proposes to use a plastic or wooden stacking support to stack two devices. For example, the stacking support is fixed to the table panel of the washing machine by screws, and then the clothes dryer is directly stacked on the support. This method only meets the stacking needs of two machines, and lacks consideration of overall stability. When the washing machine vibrates violently, the clothes dryer has a risk of falling because it is not rigidly connected to the washing machine.

[0005] In addition, the stacking support further increases the overall height of the two devices, making it inconvenient for users to operate the upper device and resulting in a poor user experience. In addition, the stacking support itself is prone to loosening.

[0006] Therefore, the present application is proposed. SUMMARY

[0007] To solve the above technical problems, the purpose of the present application is to provide a stacked clothes processing device, which connects two clothes processing devices by the fixed structure of the present application, and has higher connection stability.

[0012] The first clothes processing device and the insertion part are provided with a limiting structure and a limiting hole respectively, and the limiting structure is inserted into the limiting hole to limit the movement of the fixing structure.

[0013] In the above technical solution, the insertion direction of the insertion part and the insertion direction of the limiting structure are inclined or perpendicular to each other.

[0014] Preferably, the insertion part is inserted into the first clothes processing device along a horizontal direction, and the limiting structure is inserted into the limiting hole along a vertical direction.

[0015] In any of the above technical solutions, the connecting part and the insertion part are connected by bending, wherein the extension direction of the connecting part is parallel to the axial direction of the limiting hole; and / or

[0016] The insertion part has two opposite ends, one end of which is connected to the connecting part, and one of the limiting structure and the limiting hole is arranged on the insertion part close to the other end.

[0017] Preferably, the limiting hole is arranged on the insertion part, and the limiting structure is a limiting protrusion arranged on the first clothes processing device.

[0018] In any of the above technical solutions, the limiting structure is a limiting protrusion, and the outer surface of the limiting protrusion includes a stop surface and an arc surface or an inclined surface opposite to the stop surface, and the insertion part is inserted into the first clothes processing device along the direction from the arc surface or the inclined surface to the stop surface.

[0019] Preferably, the arc surface or the inclined surface is curved or inclined along the insertion direction of the insertion part.

[0020] In any of the above technical solutions, the first clothes processing device comprises:

[0021] a top plate;

[0023] The insertion part is provided with the limiting hole, and at least one of the top plate and the reinforcing beam is provided with the limiting structure.

[0024] In any of the above technical solutions, the limiting structure is arranged on one of the top plate and the reinforcing beam, and there is a gap between the limiting structure and the other one.

[0025] In any of the above technical solutions, the insertion part has a recessed area and a protruding area, the recessed area is in contact with the reinforcing beam, and the protruding area is in contact with the top plate, wherein,

[0026] When the limiting structure is arranged on the top plate, the limiting hole is located in the protruding area; when the limiting structure is arranged on the reinforcing beam, the limiting hole is located in the recessed area.

[0027] In any of the above technical solutions, the limiting structure is arranged on the inner surface of the top plate.

[0028] Preferably, part of the top plate is recessed inward to form the limiting structure.

[0029] In any of the above technical solutions, part of the top plate is recessed in the direction of the reinforcing beam to form a profiling structure, and the insertion part is located between the profiling structure and the reinforcing beam, wherein the limiting structure is located in the profiling structure.

During the assembly process of inserting the insertion part into the first clothes processing device by the operator, when the operator feels that the limiting structure extends into the limiting hole, it indicates that the insertion part is inserted in place, and the installation is more convenient.

DETAILED DESCRIPTION

[0058] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments will be described clearly and completely below by referring to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0059] In the description of the present application, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0060] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0061] Some embodiments of the present application will be described below with reference to the drawings.

[0062] Embodiments of the present application provide a stacked laundry processing apparatus 200, as shown in Figure 13 and Figure 14 The stacked laundry processing apparatus 200 at least includes two laundry processing devices stacked vertically, which is beneficial to save the occupied space of the devices, and the two devices are closer, which is convenient for users to operate. For example, the two laundry processing devices are both washing machines or both drying machines, or the two laundry processing devices are a washing machine and a drying machine, and the drying machine is stacked on the washing machine, which is convenient for users to take out the washed clothes and place them directly in the drying machine for subsequent drying treatment. In addition, the lighter drying machine is placed on the heavier washing machine, which is beneficial to ensure the stability of the whole. The two laundry processing devices are connected and fixed by a fixing structure, which ensures the stability of the connection of the two devices, avoids shaking, displacement and falling, and thus ensures the safety and reliability of the two devices.

[0063] As shown in Figure 13 , Figure 15 and Figure 16 Embodiments of the present application provide a stacked laundry processing apparatus 200, which includes a first laundry processing device 210, a second laundry processing device 220 and a fixing structure 100.

[0064] Specifically, the first laundry treatment device 210 and the second laundry treatment device 220 are stacked, the fixing structure 100 has the insertion part 120 inserted into the first laundry treatment device 210 and the connecting part 110 connected with the second laundry treatment device 220, so that the first laundry treatment device 210 is connected through the insertion part and the second laundry treatment device 220 is connected through the connecting part 110, thereby realizing that the fixing structure 100 connects and fixes the first laundry treatment device 210 and the second laundry treatment device 220, and avoids shaking and toppling of the stacked first laundry treatment device 210 and the second laundry treatment device 220.

[0065] And the fixing structure 100 of the embodiment has the advantages of simple structure, convenient assembly and low cost, and only needs to release the connection between the connecting part 110 and the second laundry treatment device 220 to realize the disassembly of the second laundry treatment device 220, which is more convenient to disassemble. At the same time, the insertion mode does not increase the overall height of the stacked laundry treatment equipment 200, so that the product is relatively more compact, more space-saving, and more convenient for the user to operate the first laundry treatment device 210 which is relatively higher in position, and the product use experience is better.

[0066] In some embodiments, as shown in Figure 1 , Figure 4 and Figure 6 , one of the first laundry treatment device 210 and the insertion part 120 is provided with a limiting structure 2115, and the other is provided with a limiting hole 124, and the limiting structure 2115 extends into the limiting hole 124 to limit the movement of the fixing structure 100. The limiting structure and the limiting hole 124 limit the insertion part 120, which can prevent the insertion part 120 from shaking and prevent the insertion part 120 from loosening and causing the fixing structure 100 to loosen, thereby improving the connection and fixation of the fixing structure 100, and further improving the connection firmness between the first laundry treatment device 210 and the second laundry treatment device 220. On the other hand, the limiting hole 124 and the limiting structure 2115 also have the function of positioning, and during the assembly process of inserting the insertion part 120 into the first laundry treatment device 210, when the operator feels that the limiting structure 2115 extends into the limiting hole 124, it indicates that the insertion part 120 is inserted in place, and the installation is more convenient.

[0067] In some embodiments, as shown in Figure 4 , Figure 5 and Figure 6As shown, the insertion direction of the plug-in part 120 and the extending direction of the limiting structure 2115 are inclined or perpendicular to each other, so that the limiting structure 2115 limits the plug-in part 120 in the insertion direction, increases the resistance of the plug-in part 120 to be pulled out of the first clothes processing device 210, prevents the plug-in part 120 from loosening to cause the fixing structure 100 to be loosened, and further improves the connection stability of the fixing structure 100. It should be noted that the limiting structure 2115 limits the plug-in part 120 in the insertion direction in the embodiment, which does not mean that the plug-in part 120 cannot be detached after the limiting structure 2115 extends into the limiting hole 124, but the user needs to exert more force to pull out the plug-in part 120.

[0068] In a preferred embodiment, as shown in Figure 2 、 Figure 3 and Figure 7 , the plug-in part 120 is inserted into the first clothes processing device 210 along the horizontal direction, and the limiting structure 2115 extends into the limiting hole 124 along the vertical direction, which is more convenient for the operator to operate and assemble.

[0069] In some embodiments, as shown in Figure 10 、 Figure 11 and Figure 12 , the connecting part 110 and the plug-in part 120 are connected by bending, for example, the plug-in part 120 is connected to the lower end of the connecting part 110 by bending, for example, the connecting part 110 and the plug-in part 120 form a shape similar to an "L" shape, the vertical connecting plate of the "L" shape forms the connecting part 110, and the horizontal connecting plate of the "L" shape forms the plug-in part 120. The connecting part 110 is used to connect with the side part 221 of the second clothes processing device located above, and the plug-in part 120 is used to connect with the top of the first clothes processing device 210 located below.

[0070] Therefore, the second clothes processing device 220 is connected through the connecting part 110, and the first clothes processing device 210 is connected through the plug-in part 120, so as to realize the connection and fixation of the second clothes processing device 220 and the first clothes processing device 210, and the connection stability is better. Moreover, the connecting part 110 and the plug-in part 120 are connected by bending, so that the fixing structure 100 has a certain deformation ability. When the second clothes processing device 220 shakes during operation, the second clothes processing device 220 applies a force to the connecting part 110, so that the connecting part 110 deforms and applies a counterforce to the second clothes processing device 220, slows down and weakens the shaking of the second clothes processing device 220, so that the fixing structure 100 has the functions of connection and shock absorption, further avoids the displacement and falling of the second clothes processing device 220, and improves the connection reliability of the second clothes processing device 220 and the first clothes processing device 210.

[0071] Further, asFigure 10 As shown, the extension direction of the connecting portion 110 is parallel to the axial direction of the limiting hole 124, which is more convenient for the operator to operate and assemble.

[0072] In some embodiments, the insertion portion 120 has two opposite ends, one of which is connected to the connecting portion 110, and one of the limiting structure 2115 and the limiting hole 124 is arranged on the insertion portion 120 close to the other end. It can be understood that when the insertion portion 120 is inserted in place, the connecting portion 110 is located outside the first clothes processing device 210, so that the connecting portion 110 can be connected to the second clothes processing device 220. One of the limiting structure 2115 and the limiting hole 124 is arranged away from the other end of the connecting portion 110, which avoids the limiting structure 2115 hindering the insertion of the insertion portion 120, so that the insertion portion 120 can be more smoothly inserted into the first clothes processing device 210, and the assembly is more convenient.

[0073] Further, the limiting hole 124 is arranged on the insertion portion 120, and the limiting structure 2115 is a limiting protrusion 2115a arranged on the first clothes processing device 210. Arranging the limiting hole 124 on the insertion portion 120 is beneficial to ensure the relative flatness of the surface of the insertion portion 120, so that the insertion portion 120 is more smoothly inserted before the position of the limiting protrusion 2115a, reduces the hindering of the limiting protrusion 2115a to the insertion of the insertion portion 120, and the assembly is more simple and convenient.

[0074] In some embodiments, as shown in Figure 4 , Figure 7 and Figure 8 , the limiting structure 2115 is a limiting protrusion 2115a, the outer surface of the limiting protrusion 2115a includes a stop surface 21151 and an arc surface or inclined surface 21152 opposite to the stop surface 21151, and the insertion portion 120 is inserted into the first clothes processing device 210 along the direction from the arc surface or inclined surface 21152 to the stop surface 21151. When the insertion portion 120 is inserted in place, the limiting protrusion 2115a extends into the limiting hole 124, and the stop surface 21151 of the limiting protrusion 2115a and the hole wall of the limiting hole 124 are in stop cooperation, preventing the insertion portion 120 from loosening. The arrangement of the arc surface or inclined surface 21152 further reduces the resistance of the limiting protrusion 2115a to the insertion of the insertion portion 120, reduces the wear of the limiting protrusion 2115a, ensures the limiting reliability of the limiting protrusion 2115a, prolongs the service life of the limiting protrusion 2115a, and the assembly is more simple and convenient.

[0075] Preferably, the arc surface or inclined surface 21152 is curved or inclined along the insertion direction of the plug-in part 120. More specifically, one end of the arc surface or inclined surface 21152 is connected with the inner surface of the first clothes treatment device 210, and the other end is transitionally connected with the stop surface 21151, wherein the arc surface or inclined surface 21152 extends from one end to the other end in a direction away from the inner surface of the first clothes treatment device 210.

[0076] In some embodiments, as shown in Figure 5 、 Figure 6 and Figure 9 , the first clothes treatment device 210 comprises a top plate 211 and a reinforcing beam 212. Specifically, the reinforcing beam 212 is located below the top plate 211, and the plug-in part 120 is inserted between the top plate 211 and the reinforcing beam 212 to be clamped by the top plate 211 and the reinforcing beam 212. By arranging the plug-in part 120 to be inserted between the top plate 211 and the reinforcing beam 212, on the one hand, the plug-in part 120 is clamped and fixed by the top plate 211 and the reinforcing beam 212, improving the connection stability of the plug-in part 120 and avoiding the plug-in part 120 from shaking or loosening, and on the other hand, the reinforcing beam 212 shares the stress of the top plate 211, avoiding the deformation of the top plate 211 due to stress, which is beneficial to maintaining the flatness of the top plate 211.

[0077] In further detail, the reinforcing beam 212 is located in the front area of the top plate 211, which on the one hand strengthens the strength of the end and corner of the first clothes treatment device 210, and on the other hand makes it easier for the plug-in part 120 to be inserted between the top plate 211 and the reinforcing beam 212, reduces the length of the plug-in part 120, saves materials, and reduces cost and weight.

[0078] Further, the insertion part is provided with a limiting hole 124, and at least one of the top plate 211 and the reinforcing beam 212 is provided with a limiting structure 2115.

[0079] Further, the limiting structure 2115 is arranged on one of the top plate 211 and the reinforcing beam 212, and has a gap α with the other one, which makes the plug-in part 120 more easily pass through the position where the limiting structure 2115 is located, further reduces the obstruction of the limiting structure 2115 to the insertion of the plug-in part 120, reduces the wear of the limiting structure 2115, ensures the limiting reliability of the limiting structure 2115, prolongs the service life of the limiting structure 2115, and makes the insertion simpler and more convenient.

[0080] Further, as shown in Figure 6 、 Figure 8 and Figure 10As shown, the insertion part 120 has a recessed area 123 and a protruding area 122, the recessed area 123 is in contact with the reinforcing beam 212, and the protruding area 122 is in contact with the top plate 211. The strength of the insertion part 120 is improved by the recessed area 123 and the protruding area 122, avoiding deformation and breakage of the fixing structure 100, and ensuring the connection stability and reliability of the fixing structure 100.

[0081] In some embodiments, part of the insertion part 120 is recessed in the direction of the reinforcing beam 212 to form the recessed area 123, and the other part forms the protruding area 122, which is simple to process and has higher strength.

[0082] Preferably, the recessed area 123 is in contact with the reinforcing beam 212 and spaced from the top plate 211, and the protruding area 122 is in contact with the top plate 211 and spaced from the reinforcing beam 212. The fixing structure 100, the reinforcing beam 212 and the top plate 211 respectively form point area contact through the recessed area 123 and the protruding area 122, so that the clamping force of the top plate 211 and the reinforcing beam 212 on the insertion part 120 is greater, the connection is more firm, and the fixing structure 100 is prevented from loosening.

[0083] Preferably, the recessed area 123 and the protruding area 122 extend along the extension direction of the insertion part 120, or in other words, the extension direction of the recessed area 123 and the protruding area 122 is along the insertion and extraction direction of the insertion part 120, so that the recessed area 123 and the protruding area 122 do not hinder the insertion and extraction of the insertion part 120, facilitating installation by the operator.

[0084] Preferably, the recessed area 123 and the protruding area 122 are alternately distributed to make the insertion part 120 have a concave-convex shape.

[0085] Further, the recessed area 123 includes a bottom wall 1231 and a surrounding wall 1232 arranged along the outer periphery of the bottom wall 1231, wherein the surrounding wall 1232 and the bottom wall 1231 are curvedly or obliquely transitioned, and / or the surrounding wall 1232 and the protruding area 122 are curvedly or obliquely transitioned. The recessed area 123 has a certain deformation capacity through the curved or oblique transition of the surrounding wall 1232, which weakens the rigidity of the recessed area 123. When the top plate 211 and the reinforcing beam 212 clamp the insertion part 120, the clamping force of the top plate 211 and the reinforcing beam 212 is improved through the deformation of the recessed area 123, the connection is more reliable, and the curved or oblique transition reduces the internal stress concentration points of the recessed area 123 and its surrounding area, the strength of the fixing structure 100 is higher, the risk of local stress concentration and breakage is avoided, the service life of the fixing structure 100 is prolonged, and the connection reliability of the fixing structure 100 is improved.

[0086] In some embodiments, the plug-in part 120 is provided with a plurality of recessed areas 123 and a plurality of convex areas 122 arranged alternately, which further strengthens the strength of the plug-in part 120 and improves the connection reliability of the fixing structure 100.

[0087] In some embodiments, the recessed area 123 is provided with a first connecting hole 121 for the fastener to pass through. It can be understood that the recessed area 123 is in contact with the reinforcing beam 212 and is spaced apart from the top plate 211. The recessed area 123 is provided with the first connecting hole 121, which is beneficial to avoid the situation that the reinforcing beam 212 and the fastener are disconnected due to the gap, avoid the reinforcing beam 212 from loosening, and improve the connection reliability between the reinforcing beam 212 and the plug-in part 120.

[0088] Further, the plug-in part 120 is provided with a plurality of recessed areas 123 arranged alternately, wherein the recessed areas 123 at opposite edges of the plurality of recessed areas 123 are respectively provided with the first connecting hole 121, which makes the connection more stable and reliable.

[0089] Further, as shown in Figure 6 some embodiments, the limiting structure 2115 is arranged on the top plate 211, and the limiting hole 124 is located in the convex area 122. In other embodiments, the limiting structure 2115 is arranged on the reinforcing beam 212, and the limiting hole 124 is located in the recessed area 123. In this way, the position of the limiting hole 124 is closer to the limiting structure 2115, which ensures that the limiting structure 2115 can be inserted into the limiting hole 124, guarantees the limiting reliability of the limiting structure 2115 and the limiting hole 124, and is beneficial to shorten the height of the limiting structure 2115, so that the limiting structure 2115 has a gap α with the reinforcing beam 212 (or the top plate 211) while extending into the limiting hole 124.

[0090] In some embodiments, the limiting structure 2115 is arranged on the inner surface of the top plate 211, which is beneficial to ensure that the limiting structure 2115 is inserted into the limiting hole 124 and improves the limiting reliability of the limiting structure 2115.

[0091] Further, part of the top plate 211 is recessed inward to form the limiting structure 2115, which is simpler to process and has lower cost.

[0092] Further, part of the top plate 211 is recessed in the direction of the reinforcing beam 212 to form a profiled structure 2113, and the plug-in part 120 is located between the profiled structure 2113 and the reinforcing beam 212. The profiled structure 2113 further strengthens the strength of the top plate 211 and improves the clamping force between the top plate 211 and the reinforcing beam 212.

[0093] The limiting structure 2115 is arranged on the profiling structure 2113. On the one hand, the distance between the profiling structure 2113 and the reinforcing beam 212 is shorter than that of other regions of the top plate 211. The limiting structure 2115 is arranged on the profiling structure 2113, which is beneficial to shorten the height of the limiting structure 2115 and reduce the cost while ensuring that the limiting structure 2115 extends into the limiting hole 124. On the other hand, the larger clamping force of the profiling structure 2113 further makes the limiting structure 2115 more firmly inserted into the limiting hole 124, increases the resistance of the plug-in part 120 to the first clothes treatment device 210, prevents the plug-in part 120 from loosening and causing the fixing structure 100 to be loose, and further improves the connection stability of the fixing structure 100.

[0094] In some specific embodiments, part of the profiling structure 2113 is inwardly recessed to form the limiting structure 2115.

[0095] In some specific embodiments, the profiling structure 2113 comprises a clamping wall and a peripheral wall arranged along the outer periphery of the clamping wall, wherein the limiting structure 2115 is arranged on the clamping wall to ensure the clamping effect of the clamping wall on the limiting structure 2115.

[0096] Further, the peripheral wall and the clamping wall are curvedly or obliquely transitioned. The curved or oblique transition of the peripheral wall enables the profiling structure 2113 to have a certain deformation capacity, which weakens the rigidity of the profiling structure 2113. When the top plate 211 and the reinforcing beam 212 clamp the plug-in part 120, the clamping force of the top plate 211 and the reinforcing beam 212 is improved by the deformation of the profiling structure 2113, and the connection is more reliable. The curved or oblique transition reduces the internal stress concentration points of the profiling structure 2113 and its surrounding regions, and the strength of the fixing structure is higher, which avoids the risk of local stress concentration and breakage, prolongs the service life of the fixing structure, and improves the connection reliability of the fixing structure.

[0097] Further, the clamping wall is adapted to the shape of the plug-in part 120.

[0098] Preferably, the profiling structure 2113 is provided with a corresponding second connecting hole 2114. The fastener passes through the second connecting hole 2114 of the profiling structure 2113, the first connecting hole of the plug-in part, and the third connecting hole of the reinforcing beam in sequence to lock the top plate, the fixing structure, and the reinforcing beam.

[0099] In some embodiments, the edge of the top plate 211 is rolled to form a top plate sidewall 2111, which is provided with a plug-in interface 2112, along which the plug-in part 120 extends between the top plate 211 and the reinforcing beam 212. Further, the connecting part 110 has a connecting arm 112 and a leaning arm 111 at the lower end of the connecting arm 112, which is connected to the plug-in part 120 by bending, and leans against the top plate sidewall 2111. The plug-in interface 2112 has a positioning function. During assembly, the operator inserts the plug-in part 120 along the plug-in interface 2112, that is, inserts the plug-in part 120 between the top plate 211 and the reinforcing beam 212, and the first connecting hole 121 on the plug-in part 120 and the connecting holes on the top plate 211 and the reinforcing beam 212 are also positioned in the transverse direction (i.e., the direction perpendicular to the insertion direction). When the leaning arm 111 contacts the top plate sidewall 2111, the first connecting hole 121 on the plug-in part 120 and the connecting holes on the top plate 211 and the reinforcing beam 212 are also positioned in the longitudinal direction (i.e., the insertion direction), and the limiting structure 2115 and the limiting hole 124 are also positioned synchronously, thereby eliminating the process of alignment and adjustment by the operator, and making installation more convenient.

[0100] In a specific embodiment, the plug-in interface 2112 and the upper end of the top plate 211 have a spacing. As can be understood, after the fastener locks the top plate 211, the plug-in part 120 and the reinforcing beam 212, one end of the first connecting hole 121 of the plug-in part 120 is pressed to one side of the top plate 211 by the reinforcing beam 212 to a certain extent, while the other end of the plug-in part 120 is limited by the plug-in interface 2112, resulting in that one end of the first connecting hole 121 of the plug-in part 120 is inclined upward relative to the other end, so that the plug-in part 120 is less likely to be loosened from the plug-in interface, and the connection is more secure.

[0101] In some embodiments, as shown in Figure 13 The second laundry treatment device 220 is located above the first laundry treatment device 210, the connecting part 110 of the fixing structure 100 is connected to the side part 221 of the second laundry treatment device, and the plug-in part 120 of the fixing structure 100 is connected to the top part of the first laundry treatment device 210.

[0102] For example, the second laundry treatment device 220 is a clothes dryer, and the first laundry treatment device 210 is a washing machine. The fixing structure 100 is located at the front side of the clothes dryer and the washing machine. The fixing structure 100 is substantially in the shape of “L”, which includes the connecting part 110 and the plug-in part 120. The connecting part 110 is connected to the side part of the clothes dryer, and the plug-in part 120 is connected to the top part of the washing machine. In detail, the vertical connecting part 110 of the “L” shape is connected to the lower area of the front plate 2211 of the clothes dryer, and the transverse plug-in part 120 of the “L” shape is connected to the front edge area of the top plate 211 of the washing machine.

[0103] In some embodiments, as shown in Figure 10 、 Figure 11 and Figure 12 , the connecting part 110 includes a leaning arm 111 and a connecting arm 112, in detail, the leaning arm 111 is located below the connecting arm 112, one end of the leaning arm 111 is connected with the bending of the plug-in part 120, and the leaning arm 111 is adapted to lean against the top plate side wall 2111 of the first clothes processing device 210; the connecting arm 112 is connected with the other end of the leaning arm 111, and the connecting arm 112 is used to be connected with the side wall of the side part 221 of the second clothes processing device.

[0104] The connecting and fixing of the fixed structure 100 and the second clothes processing device 220 is realized through the connecting arm 112, the bending connection of the connecting arm 112 and the plug-in part 120 is realized through the leaning arm 111, and the leaning arm 111 is made to lean against the top plate side wall 2111. Through the leaning cooperation of the leaning arm 111 and the top plate side wall 2111, on the one hand, the leaning arm 111 can move relative to the top plate side wall 2111, so that the leaning arm 111 has a certain deformation ability relative to the plug-in part 120. After the second clothes processing device 220 shakes, the second clothes processing device 220 drives the connecting arm 112 to shake synchronously, the shaking of the connecting arm 112 makes the leaning arm 111 move relative to the top plate side wall 2111 and applies a counterforce to the second clothes processing device 220, so as to slow down and weaken the shaking of the second clothes processing device 220. The deformation of the leaning arm 111 reduces the stress of the plug-in part 120, avoids the direct stress of the fastener, the limiting structure 2115 and other structures, reduces the risk of loosening of the fastener, and further ensures the connection reliability between the second clothes processing device 220 and the first clothes processing device 210. On the other hand, the leaning arm 111 also has the function of positioning, and the leaning arm 111 is stopped by the top plate side wall 2111, so that the plug-in part 120 is installed in place, which is convenient for the assembly operation of the staff.

[0105] For example, the second clothes processing device 220 is a clothes dryer, and the clothes dryer is formed by a cabinet 210a surrounded by a front plate 2211, a rear plate, a left side plate and a right side plate, and a drying cylinder, a driving device, a drying system and other structures are installed in the cabinet 210a, wherein the bottom end of the front plate 2211 forms a side wall into the cabinet 210a through two flanges, more specifically, the bottom end of the front plate 2211 first forms a horizontal flange into the cabinet 210a, and the end of the horizontal flange away from the front plate 2211 is flanged along a vertical direction, and the vertical flange is the side wall of the side part 221 of the second clothes processing device; the first clothes processing device 210 is a washing machine, which comprises a cabinet 210a, and a top plate 211 is arranged above the cabinet 210a, and a reinforcing beam 212 is arranged on the lower side of the top plate 211, wherein the insertion part 120 is inserted between the top plate 211 and the reinforcing beam 212, the abutting arm 111 abuts on the side wall 2111 of the top plate, and the connecting arm 112 is located above the top plate 211 and connected to the bottom of the front plate 2211 of the clothes dryer.

[0106] Preferably, the connecting arm 112 is provided with a third connecting hole 114, and a fastener passes through the third connecting hole 114 to lock the fixing structure 100 to the second clothes processing device 220, so that the connection is simpler, more convenient and more stable.

[0107] In some embodiments, the connecting part 110 and the insertion part 120 are respectively provided with a reinforcing structure 113 to improve the strength of the connecting part 110 and the insertion part 120.

[0108] In detail, part of the insertion part 120 is recessed to form a recessed area 123 in the direction of the reinforcing beam 212, and the other part forms a protruding area 122, wherein the recessed area 123 is formed as a reinforcing structure 113 of the insertion part 120 to improve the strength of the insertion part 120.

[0109] Further, part of the abutting arm 111 is protruded to form the reinforcing rib in the direction away from the insertion part 120.

[0110] Part of the connecting part 110 is protruded to form the reinforcing structure 113 in the direction of the side part 221 of the second clothes processing device to improve the strength of the connecting part 110.

[0111] More specifically, the abutting arm 111 and the connecting arm 112 of the connecting part 110 are respectively provided with a reinforcing structure 113. The reinforcing structure 113 on the connecting arm 112 forms a point area contact with the side part 221 of the second clothes processing device, so that the connection between the connecting arm 112 and the side part 221 of the second clothes processing device is more firm.

[0112] Further, the reinforcing structure 113 on the insertion part 120 and the upper reinforcing structure 113 of the connecting part 110 are integrally formed.

[0113] In some embodiments, the extension direction of the lap arm 111 is the same as the extension direction of the connecting arm 112. The lap arm 111 and the connecting arm 112 may be in the same plane or they may not be coplanar.

[0114] In detail, such as Figure 10 As shown, a bending structure 115 is formed at the connection between the lap arm 111 and the connecting arm 112. This bending structure 115 further increases the deformation between the lap arm 111 and the connecting arm 112, relatively weakening the rigidity of the connecting arm 112. When the second garment handling device 220 shakes during operation, it applies a force to the connecting arm 112. Under the action of the second garment handling device 220, the connecting arm 112 deforms and bends relative to the lap arm 111, and applies a reaction force to the second garment handling device 220. On the one hand, it reduces and weakens the shaking of the second garment handling device 220. On the other hand, the second garment handling device 220 drives the connecting arm 112 to shake synchronously. The second garment handling device 220 and the connecting arm 112 are close to each other without generating a force to separate them. This avoids the situation where the second garment handling device 220 and the connecting arm 112 are misaligned, and also avoids the risk of the fasteners connecting the second garment handling device 220 and the connecting arm 112 being loosened by force. This makes the connection between the second garment handling device 220 and the connecting arm 112 more secure and the connection stability better.

[0115] Furthermore, in the above-described structural form, when the second garment handling device 220 shakes, the lap arm 111 relative to the first garment handling device 210 remains stationary or its movement is significantly reduced compared to a structure without the bending structure 115. This reduces the number of bends and the degree of bending of the lap arm 111 relative to the insertion part 120, thereby greatly reducing the risk of the lap arm 111 breaking. This extends the service life of the fixing structure 100 and ensures the connection reliability of the fixing structure 100. At the same time, due to the reduced movement of the lap arm 111, the force transmitted from the lap arm 111 to the insertion part 120 is correspondingly reduced, making it less likely for the insertion part 120 to move relative to the first garment handling device 210. This prevents the insertion part 120 from misaligning or loosening, improving the connection reliability between the insertion part 120 and the first garment handling device 210. Conversely, when the first garment handling device 210 shakes, the bending structure 115 blocks or weakens the force transmission from the insertion part 120 to the connecting arm 112, making the second garment handling device 220 relatively more stable.

[0116] In summary, by arranging the bending structure 115 between the abutting arm 111 and the connecting arm 112, the fixing structure 100 is connected to the second laundry treatment device 220 and the first laundry treatment device 210 more firmly, and thus the second laundry treatment device 220 and the first laundry treatment device 210 are more stable.

In other embodiments, the washing machine and the drying machine have common components, for example, the washing machine and the drying machine share an air duct, so that the airflow generated by the operation of the drying machine can be used by the washing machine through the shared air duct. Because of the common components, the washing machine and / or the drying machine cannot work independently, and some functions must rely on the other to be completed, and the two must be assembled during use.

Further, the control panel 222 is located at the upper end of the clothes dryer.

[0123] The clothes dryer has an accommodation space enclosed by a front plate 2211, side plates and a rear plate, and components such as a washing drum are located in the accommodation space. The front plate 2211 is provided with a door for taking and placing clothes. The bottom end of the front plate 2211 is first formed into a horizontal direction flange inwardly, and the end of the horizontal direction flange away from the front plate 2211 is formed into a vertical direction flange. The vertical direction flange is a first wall, and the horizontal direction flange is a second wall. The first wall and the second wall are used to be connected with the connecting part 110.

[0124] As to the fixing structure 100, it is used to connect and fix the washing machine and the clothes dryer, and prevent the clothes dryer from tilting and falling.

[0125] The fixing structure 100 is a metal piece in the shape of "L" generally, which includes a connecting part 110 in the vertical direction and a plug-in part 120 in the horizontal direction. The connecting part 110 includes connecting arms 112 and a leaning arm 111 distributed upward and downward. The leaning arm 111 is connected with the plug-in part 120 by bending. The connecting arms 112 are connected with the clothes dryer. The plug-in part 120 is connected with the washing machine, so that the washing machine and the clothes dryer are connected and fixed by the fixing structure 100.

[0126] Specifically, the plug-in part 120 extends into the space between the top plate 211 and the reinforcing beam 212, and the top plate 211, the plug-in part 120 and the reinforcing beam 212 are locked by fasteners, so that the connection is reliable.

[0127] Further, the front end of the top plate 211 is bent downward to form a top plate side wall 2111, and the top plate side wall 2111 is provided with a plug-in port 2112.

The end of the connecting arms 112 is bent in the horizontal direction to form a supporting arm, and the second wall of the clothes dryer is abutbed against the supporting arm.

[0128] Further, the limiting hole 124 is arranged on the plug-in part 120, and the inner surface of the top plate 211 is provided with the limiting protrusion 2115a.
