They are only for the convenience of describing the embodiments of the present application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the embodiments of the present application.

[0031] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The present application embodiment provides a clothes processing device 1, see Figures 1 to 4 , including a shell 10, a frame 11 and a barrel assembly.

[0033] One side of the lower end of the housing 10 has an opening 10a, and the frame 11 is disposed in the housing 10. The frame 11 has a first space 11a and a second space 11b located below the first space 11a, the barrel assembly is disposed in the first space 11a, and the opening 10a is communicated with the second space 11b for the cleaning robot to enter and exit the second space 11b.

[0034] The housing 10 is an appearance component of the clothes processing device 1, and can protect the internal drum assembly and the cleaning robot.

[0035] The drum assembly has a clothes processing chamber for holding clothes. Exemplarily, in some examples, the drum assembly includes an outer drum and an inner drum, the outer drum is sleeved on the outside of the inner drum, the outer drum is used to hold water, and the inner drum is used to hold clothes. In this embodiment, the inner drum holds water through the outer drum, and the inner drum can also be called a perforated inner drum. In other embodiments, the inner drum holds water by itself, and can also be called a non-perforated inner drum, and the outer drum can be set outside the inner drum, or it can be set without the outer drum.

[0036] The cleaning robot can be used to automatically clean dust and hair on the ground. When a mop is provided on the cleaning robot, the cleaning robot can mop the ground after cleaning it.

[0037] It can be understood that the clothes processing device 1 of this embodiment includes at least one of charging, dust removal, washing, drying and disinfecting the cleaning robot.

[0038] The first space 11a is used to provide an installation space for the barrel assembly, and the second space 11b is used to provide a receiving space for the cleaning robot. The cleaning robot can enter or leave the second space 11b through the opening 10a.

[0039] The frame 11 is a load-bearing component that can bear vertical load and resist horizontal forces. When the cylinder assembly is arranged in the first space 11a and the cleaning robot is accommodated in the second space 11b, the frame 11 can bear the weight of the cylinder assembly and its load, the weight of the cleaning robot and its load, and provide support for the cylinder assembly and the cleaning robot to improve the installation stability of the cylinder assembly and the storage reliability of the cleaning robot.

[0040] In the related art, the clothing processing machine is used to wash and care for clothing, and the base assembly is used to accommodate a cleaning robot. The clothing processing machine and the base assembly are integrated together by stacking them up and down, and the base bears the weight of the clothing processing machine and its load. On the one hand, the clothing processing machine and the base assembly are two independent components with a low degree of integration. On the other hand, the base is larger than the size of the clothing processing machine to increase the stability of the integration and reserve a safe distance for the clothing processing machine to reduce the chance of the clothing processing machine vibrating and displacing and falling. However, this method has low space utilization and still requires a large space, and the appearance of the integrated clothing processing machine and the base assembly is low.

[0041] The clothing processing device 1 provided in the embodiment of the present application is provided with a first space 11a and a second space 11b through a frame 11 to accommodate a drum assembly and a cleaning robot. The clothing processing device 1 as an independent component can realize clothing washing and sweeping cleaning in one step. The frame 11 serves as a load-bearing component to support the drum assembly and the cleaning robot. The overall structure has high strength and better vibration resistance. In addition, since the outer shell 10 does not need to bear the weight of the drum assembly, the structural strength requirements of the outer shell 10 can be reduced, thereby reducing the manufacturing difficulty and manufacturing cost of the outer shell 10, and it is also convenient to realize a richer process design of the outer shell 10. Moreover, the overall visual appearance of the clothing processing device 1 is more coordinated and neat, and the overall aesthetics is high.

[0042] When assembling the clothes processing device 1 provided in the embodiment of the present application, the drum assembly and the frame 11 are assembled first. Since the surrounding of the frame 11 is open space, there is a large amount of operating space and a large operating field of view, which is convenient for the assembler to operate and assemble. In the related art, the drum assembly is placed in a box, and then other parts are installed. However, due to the obstruction of the box, the operating field of view and operating space are very small, which is not conducive to assembly.

[0043] The specific structure of the frame 11 is not limited.

[0044] For some examples, see Figure 3 The frame 11 includes a plurality of longitudinal beams 111 and a spacing component 112. The spacing component 112 is disposed in an area defined by the plurality of longitudinal beams 111 and connected to each longitudinal beam 111. The spacing component 112 separates the area enclosed by the plurality of longitudinal beams 111 into a first space 11a and a second space 11b.

[0045] It can be understood that the longitudinal beam 111 is a beam extending in the longitudinal direction, specifically, a beam extending in the height direction of the clothes processing device 1 .

[0046] The multiple longitudinal beams 111 are jointly stressed, and the weight of the barrel assembly and its load is transferred to the longitudinal beams 111 for support. The spacing component 112 divides the area surrounded by the multiple longitudinal beams 111, separating the installation area of ​​the barrel assembly and the accommodation area of ​​the cleaning robot, so that the clothing processing device 1 can simultaneously realize the functions of clothing washing and sweeping. In addition, the spacing component 112 can also serve as a stress-bearing component, bearing the weight of the barrel assembly and its load and providing support for the cleaning robot, thereby increasing the structural stability of the clothing processing device 1.

[0047] The longitudinal beam 111 and the spacer assembly 112 can be made of metal to have sufficient structural strength. Of course, the longitudinal beam 111 and the spacer assembly 112 can also be made of plastic parts as long as the structural strength can meet the requirements. It should be noted that metal parts can also be added on the basis of injection molding to enhance the structural strength.

[0048] The longitudinal beam 111 may be formed in any manner.

[0049] In some embodiments, the single longitudinal beam 111 is a one-piece structure.

[0050] That is, the single longitudinal beam 111 is integrally formed, which is convenient for forming on the one hand; on the other hand, when the spacer component 112 is connected to the longitudinal beam 111 and separates the first space 11a and the second space 11b, the number of connections between the spacer component 112 and the longitudinal beam 111 can be reduced. When the spacer component 112 is connected to the single longitudinal beam 111, it only needs to be connected once. In this way, the installation process can be reduced. For example, when the spacer component 112 is connected to the longitudinal beam 111 located on the front left side, it only needs to be connected once.

[0051] Of course, in other embodiments, the single longitudinal beam 111 may also be a split structure.

[0052] For example, see Figure 3 The longitudinal beam 111 includes a first sub-segment 1111 and a second sub-segment 1112. The first sub-segment 1111 extends from the top end of the frame 11 to the spacing component 112, and the second sub-segment 1112 extends from the bottom end of the frame 11 to the spacing component 112. The first sub-segment 1111 and the second sub-segment 1112 are split structures.

[0053] In this embodiment, when the spacer component 112 is connected to the single longitudinal beam 111, two connection steps are required. Specifically, the spacer component 112 can be first connected to the first sub-segment 1111 and then connected to the second sub-segment 1112. Alternatively, the spacer component 112 can be first connected to the second sub-segment 1112 and then connected to the first sub-segment 1111. Of course, the first sub-segment 1111 and the second sub-segment 1112 can also be first connected, and then the connection between the first sub-segment 1111 and the second sub-segment 1112 is connected to the spacer component 112. In this way, the connection between the spacer component 112 and the single longitudinal beam 111 is achieved.

[0054] In this embodiment, the first sub-segment 1111 and the second sub-segment 1112 are split structures, which can facilitate the connection between the spacing assembly 112 and the single longitudinal beam 111, increase the convenience of connection, and also increase the stability of connection. At the same time, when the second sub-segment 1112 is manufactured, it is also possible to more conveniently increase the structural strength of the second sub-segment 1112, thereby increasing the supporting stability of the longitudinal beam 111 on the cylinder assembly.

[0055] In some embodiments, the cross-sectional area of ​​the portion of the longitudinal beam 111 located above the spacer assembly 112 is not greater than the cross-sectional area of ​​the portion of the longitudinal beam 111 located below the spacer assembly 112 .

[0056] In this way, the portion of the longitudinal beam 111 located below the spacing assembly 112 can have sufficient structural strength to provide sufficient support for the drum assembly above, thereby improving the structural stability of the clothing processing device 1.

[0057] It should be noted that, in this embodiment, the cross-sectional area of ​​the longitudinal beam 111 is the area of ​​the cross section of the longitudinal beam 111 along a direction perpendicular to the height direction.

[0058] It should be noted that in the embodiment of the present application, the height direction is consistent with the up-down direction and the top-bottom direction.

[0059] In some embodiments, the laundry processing apparatus 1 comprises a vibration damper, and the drum assembly is supported on the spacer assembly 112 via the vibration damper.

[0060] It should be noted that the vibration absorber is a structure whose material itself has a vibration-absorbing effect. The vibration absorber can adopt the vibration absorber in the prior art, which will not be described in detail here.

[0061] The barrel assembly is supported on the spacer assembly 112 by a shock absorber. The shock absorber can separate the barrel assembly from the spacer assembly 112, that is, the barrel assembly will not be in direct contact with the spacer assembly 112. The shock absorber is located on the force transmission path between the barrel assembly and the spacer assembly 112. The shock absorber can absorb part of the vibration. In this way, when the clothing processing device 1 is performing clothing washing and care, the vibration and noise transmitted from the barrel assembly to the spacer assembly 112 can be reduced, thereby increasing the operating stability of the clothing processing device 1.

[0062] The number of longitudinal beams 111 is not limited. For example, in some embodiments, the number of longitudinal beams 111 is at least four and defines a quadrilateral structure, and the longitudinal beams 111 are located at the vertex positions of the quadrilateral.

[0063] See also Figure 3 The frame 11 includes a connecting beam 113 , which is connected between the top ends of the two longitudinal beams 111 on the front side.

[0064] That is to say, the top ends of the two longitudinal beams 111 on the front side are connected by a connecting beam 113, and the connecting beam 113 is one of the sides of the quadrilateral. On the one hand, the connecting beam 113 can connect the two longitudinal beams 111 on the front side so that the two longitudinal beams 111 are not subjected to dispersed forces. The two longitudinal beams 111 are subjected to the forces together, which can increase the overall bearing capacity of the longitudinal beams 111. On the other hand, the connecting beam 113 can also balance the forces on the longitudinal beams 111, increase the structural stability of the top ends of the longitudinal beams 111, and thus increase the overall reliability of the clothing processing device 1.

[0065] It should be noted that a quadrilateral is a closed plane figure or solid figure formed by four non-colinear and non-intersecting line segments connected end to end. A quadrilateral can be a rectangle, square, rhombus, etc. For example, please refer to Figure 3 There are four longitudinal beams 111 defining a rectangular structure. The longitudinal beams 111 are located at the top corners of the rectangle, and the connecting beam 113 is one of the sides of the rectangle.

[0066] The connection method between the connecting beam 113 and the longitudinal beam 111 is not limited, and can be welding, threaded connection, etc.

[0067] For some examples, see Figure 3 The frame 11 includes two cross beams 114 , and the cross beam 114 is connected between the top ends of the two longitudinal beams 111 located on the same side in the left-right direction.

[0068] Specifically, two longitudinal beams 111 are located on the left side and connected by one of the cross beams 114. Specifically, the two longitudinal beams 111 located at the left front and the left rear are connected by one of the cross beams 114. The other two longitudinal beams 111 are located on the right side and connected by another cross beam 114. Specifically, the two longitudinal beams 111 located at the right front and the right rear are connected by another cross beam 114.

[0069] In this embodiment, the top ends of the left and right longitudinal beams 111 are connected by a cross beam 114, which improves the rigidity of the longitudinal beams 111 and reduces the probability of lateral deflection. They can bear force together to increase the overall bearing capacity and the structural stability of the top ends of the longitudinal beams 111, thereby increasing the overall reliability of the clothing processing device 1.

[0070] The connection method between the cross beam 114 and the longitudinal beam 111 is not limited, and can be welding, threaded connection, etc.

[0071] The clothes processing device 1 comprises a suspension assembly, one end of which is connected to the drum assembly, and the other end of which is connected to the crossbeam 114 .

[0072] That is to say, the cylinder assembly is connected to the cross beam 114 through the suspension assembly. Specifically, the bottom end of the cylinder assembly is supported on the spacer assembly 112 through the shock absorber, and the left and right ends of the cylinder assembly are supported on the cross beam 114 through the suspension assembly. The cross beam 114 and the spacer assembly 112 jointly provide support for the cylinder assembly, thereby increasing the installation stability of the cylinder assembly, thereby increasing the structural stability of the clothing processing device 1.

[0073] The specific structure of the suspension assembly is not limited. For example, the suspension assembly may include a plurality of suspension springs, and the cylinder assembly is connected to the crossbeam 114 via the plurality of suspension springs.

[0074] In some embodiments, the frame 11 includes at least one mounting plate 115; the mounting plate 115 is connected between two longitudinal beams 111 located on the same side in the left-right direction, and the mounting plate 115 is located below the cross beam 114; and / or, the mounting plate 115 is connected between two longitudinal beams 111 located on the rear side, and the height of the mounting plate 115 does not exceed the cross beam 114.

[0075] The mounting plate 115 can increase the structural strength of the frame 11 . In addition, the mounting plate 115 provides a mounting location for components inside the laundry processing apparatus 1 .

[0076] It should be noted that the number of the mounting plates 115 may be one or more.

[0077] When the number of the mounting plate 115 is one, the mounting plate 115 can be connected to the two longitudinal beams 111 on the left side, or to the two longitudinal beams 111 on the right side, or to the two longitudinal beams 111 on the rear side. Figure 3 The number of the mounting plate 115 is one and it is connected to the two longitudinal beams 111 at the rear side.

[0078] When there are multiple mounting plates 115 , for example, three mounting plates 115 , the three mounting plates 115 may be respectively connected to the two longitudinal beams 111 on the left side, the two longitudinal beams 111 on the right side, and the two longitudinal beams 111 on the rear side.

[0079] For some examples, see Figure 1 The housing 10 includes a front plate 101 and two side plates 102. The two side plates 102 are located on the left and right sides of the front plate 101. The front plate 101 is provided with a clothing inlet 10b and an opening 10a. The opening 10a is provided below the clothing inlet 10b.

[0080] Specifically, the user can put clothes into or take out clothes from the clothes processing chamber through the clothes putting port 10b. The clothes putting port 10b and the opening 10a are located together at the front side, which can facilitate the operation of the user.

[0081] The size of the opening 10a along the left-right direction is not less than the inner diameter of the clothing loading port 10b. In this way, the cleaning robot can have a more reasonable size, which is convenient for floor cleaning.

[0082] It is understood that in some embodiments, please refer to Figure 2 The clothes processing device 1 may also be provided with a climbing plate 12 to increase the convenience for the cleaning robot to enter and exit the second space 11b.
