Description

Technical Field

[0001] This invention belongs to the technical field of washing machine transportation auxiliary equipment, specifically, it relates to a washing machine packaging and transportation structure. Background Technology

[0002] Washing machines include top-loading washing machines and front-loading washing machines. Front-loading washing machines mainly wash clothes through impact washing, which creates a washing structure that is less likely to damage clothes. To make it easier for the operator to load and unload clothes, front-loading washing machines are designed with an inclined front-loading design, where the rotation axis is tilted and the rotating drum opens to one side at an angle.

[0003] The inner drum module in a drum washing machine is the core component of the washing machine. Because the washing machine is designed to cushion vibrations, it is designed to allow for jumping. However, during the transportation of the whole machine, the inner drum is subjected to external transportation bumps or drops, causing damage to the inner drum module. In addition, commercial washing machines require a relatively large washing drum capacity. To ensure the reliability of the whole machine, the inner and outer drum modules and the shock absorption system are designed to be relatively heavy.

[0004] In addition, inclined drum washing machines are often used in engineering projects. During transportation, the whole machine is inevitably subjected to rough handling, which may cause the whole machine to fall and damage the whole machine and inner drum module. Summary of the Invention

[0005] The purpose of this invention is to provide a packaging and transportation structure for washing machines to solve the problems existing in the prior art, such as the inner drum of existing washing machines, especially tilting drum washing machines, being damaged by bumps and impacts during transportation due to their own working structure characteristics, which affects product quality.

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution: This invention proposes a packaging and transportation structure for a washing machine, comprising: A reinforcing member for connecting to the outer wall of the housing, the reinforcing member having at least one positioning hole and at least one limiting hole; A fastening assembly, which is connected in the corresponding positioning hole, is used to connect the inner cylinder to the housing; The fastening assembly includes a guide member, a fastener, and a limiting member for connecting the guide member to the reinforcing member. The guide member includes a guide sleeve and a positioning portion formed at one end of the guide sleeve. A guide channel is formed inside the guide sleeve, and a limiting portion is formed on the outer wall of the guide sleeve. In the installed state, the fastener passes through the guide channel, and its connecting end is detachably connected to the inner cylinder. The guide sleeve is located between the inner cylinder and the reinforcing member. A rotating neck is formed between the positioning part and the guide member, and a limiting part is formed on the guide member; after the guide sleeve is connected to the positioning hole, the guide member rotates at an angle until the limiting part corresponds to the limiting hole, and the limiting member positions the guide member on the reinforcing member.

[0007] In some embodiments of this application, the shape of the positioning hole is adapted to the cross-sectional shape that is perpendicular to the centerline of the guide sleeve and passes through the limiting portion.

[0008] In some embodiments of this application, at least one positioning notch is formed on the positioning part, and a positioning protrusion adapted to the position of the positioning notch is formed on the limiting member.

[0009] In some embodiments of this application, a fastening washer is further provided between the operating end of the fastener and the positioning part.

[0010] In some embodiments of this application, a buffer portion is further provided between the fastening gasket and the positioning portion, and a through hole is formed in the middle of the buffer portion, the fastening gasket, and the limiting member.

[0011] In some embodiments of this application, the limiting member is a limiting gasket formed between the buffer portion and the positioning portion, and the positioning protrusion is formed on the limiting member and extends toward the positioning portion.

[0012] In some embodiments of this application, the two ends of the reinforcing member are detachably connected to the housing by fastening screws, and a profile extending away from the housing is formed on the reinforcing member, and the positioning hole and the limiting hole are both formed at the bottom of the profile.

[0013] In some embodiments of this application, two reinforcing members are spaced apart on the back side of the housing, and each reinforcing member has at least one positioning hole at both ends. Correspondingly, a threaded hole is provided at the bottom of the inner cylinder, and the connecting end of the fastener is formed with an external thread. The connecting end is detachably connected to the threaded hole.

[0014] In some embodiments of this application, at least one reinforcement is formed on the sidewall of the threaded hole, the reinforcement being a groove-shaped structure that gradually expands away from the center of the threaded hole.

[0015] In some embodiments of this application, a support member is further provided at the bottom of the inner cylinder, the bottom of the support member is connected to the bottom of the box body, and a conformal surface is formed on the support member that contacts and connects with the outer wall of the inner cylinder.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are: The washing machine packaging and transportation structure involved in this application has reinforcing members and fastening components on the outer wall of the box to strengthen the connection between the box and the inner drum, and to change the movable connection between the inner drum and the box to a fixed connection. The reinforcing members on the box provide a fixed foundation for the connection of the fastening components. One end of the fastener in the fastening components is fixed to the reinforcing member, and the other end extends from the guide member to the inner drum and connects with the inner drum. The guide member can improve the structural strength of the fastener, fix the relative position between the inner drum and the box, and reduce the vibration of the inner drum. In addition, the limiting component can fix the position of the guide component, preventing the guide component from rotating or coming out of the positioning hole during the fastener connection process, making the fastener installation process simple, quick and convenient.

[0026] refer to Figure 1This application proposes a packaging and transportation structure for a washing machine, which is used to fix the inner drum 200 of the washing machine during transportation to prevent it from shaking or swaying during transportation or handling, thus avoiding damage to the inner drum 200 module.

[0027] Especially for inclined drum washing machines, due to their heavy weight, a compression spring 800 and a shock absorber 700 are installed at the bottom of the inner drum, and a tension spring 500 is installed at the top of the inner drum to help support the inner drum.

[0028] The compression spring 800 is used to support the weight of the entire inner drum 200, including the weight of the inner drum 200 itself and the weight of the clothes and washing water. Therefore, it should be installed at the center of gravity of the inner drum as much as possible. Alternatively, a figure-eight installation method can be used, which can both support the weight and reduce vibration.

[0029] Multiple pull rods 600 parallel to the rotation axis of the washing machine are provided outside the inner drum 200. The two ends of the pull rods 600 are connected to the front counterweight and the rear counterweight of the washing machine, respectively.

[0030] The front and rear counterweights can offset some of the centrifugal force generated during the operation of the inner drum, reducing the total centrifugal force that the tension spring 500 and damping support rod need to overcome, and ultimately reducing the vibration and noise experienced by the entire washing machine.

[0031] The tension spring 500 is connected to the top of the housing 100 at the top and to the pull rod 600 at the bottom. Multiple hanging positions are set on the top of the housing 100. The hanging position of the tension spring 500 can be adjusted at any time according to the center of gravity, which avoids damage to the inner cylinder 200 when the tension spring 500 is directly hung on the inner cylinder 200.

[0032] refer to Figures 1-3 The packaging and transport structure of the washing machine includes a reinforcing member 300 and a fastening component 400. The reinforcing member 300 is pre-fixed to the outer wall of the box 100. One end of the fastening component 400 is connected to the reinforcing member 300, and the other end extends into the box 100 until it is connected and fixed to the inner drum 200, thereby fixing the inner drum 200 to the box 100.

[0033] The number of reinforcing members 300 can be set according to actual needs. They can be set horizontally or at an angle. When multiple reinforcing members 300 are set, each reinforcing member 300 is set at intervals.

[0034] In some embodiments of this application, there are two reinforcing members 300, which are arranged vertically at intervals on the housing 100. The reinforcing members 300 are installed horizontally, and the two reinforcing members 300 are defined as a first reinforcing member 310 and a second reinforcing member 320 located below the first reinforcing member 310.

[0035] The first reinforcing member 310 and the second reinforcing member 320 are respectively provided with at least one positioning hole and at least one limiting hole 303 at both ends.

[0036] refer to Figure 4 The positioning hole is used to connect the fastening assembly 400, and the limiting hole 303 is used to position the guide 410 in the fastening assembly 400.

[0037] The fastening assembly 400 is divided into a first fastening assembly 401 connected to the first reinforcing member 310 and a second fastening assembly 402 connected to the second reinforcing member 320, depending on its specific connection position.

[0038] refer to Figures 11-14 The fastening assembly 400 includes a guide 410, a fastener 420, and a limiting member 430 for connecting the guide 410 to the reinforcing member 300. The guide 410 includes a guide sleeve 411 and a positioning part 412 formed at one end of the guide sleeve 411. The size of the positioning part 412 is larger than the positioning hole and is used to position the guide 410 in the length direction.

[0039] A guide channel is formed inside the guide sleeve 411. The fastener 420 passes through the guide channel. The connecting end 421 of the fastener 420 passes through the guide channel and connects to the inner cylinder 200. The operating end 422 of the fastener 420 is exposed on the outside of the reinforcing member 300, which is convenient for operators to install and disassemble.

[0040] A limiting part is formed on the outer wall of the guide sleeve 411. During installation, the guide sleeve 411 is installed from the positioning hole between the reinforcing member 300 and the inner cylinder 200. After installation, the guide sleeve 411 is rotated so that the limiting part abuts against the inner side of the reinforcing member 300 to prevent the guide sleeve 411 from coming out of the positioning hole.

[0041] refer to Figure 6 In some embodiments of this application, the reinforcing member 300 is disposed on the rear wall of the housing 100, the fastening component 400 is connected and fixed to the bottom of the inner cylinder 200, and the bottom of the inner cylinder 200 is formed with an inner cylinder fixing position 210. The number of inner cylinder fixing positions 210 is set according to actual needs, and each fastening component 400 is connected to the corresponding inner cylinder fixing position 210.

[0042] In some embodiments of this application, four inner cylinder fixing positions 210 are provided on the bottom periphery of the inner cylinder 200, and at least two positioning holes are provided on the first reinforcing member 310 and the second reinforcing member 320 respectively, and each positioning hole corresponds to at least one limiting hole 303.

[0043] Drum washing machines are divided into horizontal drum washing machines with a horizontal rotation axis and inclined drum washing machines with an inclined rotation axis. The packaging and transportation structure involved in this application can be applied to both horizontal drum washing machines and inclined drum washing machines.

[0044] When applied to a horizontal drum washing machine, the first reinforcing member 310 and the second reinforcing member 320 are at the same length from the inner drum 200, and the fastening assembly 400 connected to the first reinforcing member 310 and the second reinforcing member 320 is at the same length.

[0045] When applied to an inclined drum washing machine, since the height of the opening end of the inclined drum washing machine is higher than the bottom of the inner drum 200, the distance between the first reinforcing member 310 and the bottom of the drum is greater than the distance between the second reinforcing member 320 and the inner drum 200.

[0046] Correspondingly, the length of the fastening component 400 connected to the first reinforcing member 310 is greater than the length of the fastening component 400 connected to the second reinforcing member 320.

[0047] Both the first reinforcing member 310 and the second reinforcing member 320 are horizontal fixed plate structures. The two ends of the first reinforcing member 310 are provided with two first positioning holes 301 corresponding to the positions of the inner cylinder fixing positions 210. The two ends of the second reinforcing member 320 are provided with two second positioning holes 302 corresponding to the two inner cylinder fixing positions 210 below the inner cylinder 200.

[0048] Fixed foot plates 304 are formed at both ends of the first reinforcing member 310 and the second reinforcing member 320, respectively. Fixed holes 305 are provided on the fixed foot plates 304 for fastening screws to fix the first reinforcing member 310 and the second reinforcing member 320 to the housing 100.

[0049] A profile 306 extending away from the inner cylinder 200 is formed between the fixed foot plates 304. The first positioning hole 301 and the second positioning hole 302 are both provided on the profile 306 corresponding to the first reinforcing member 310 and the second reinforcing member 320.

[0050] refer to Figure 5 The distance between the two first positioning holes 301 on the inclined drum washing machine is smaller than the distance between the two second positioning holes 302. In order to improve the versatility between the first reinforcing member 310 and the second reinforcing member 320 and reduce the processing and mold opening cost, a set of first positioning holes 301 and second positioning holes 302 are respectively provided on the first reinforcing member 310 and the second reinforcing member 320.

[0051] refer to Figure 6-8 In some embodiments of this application, the outer wall of the guide member 410 includes two opposing planar outer walls 4111, and between the two adjacent planar outer walls 4111 is an outwardly protruding arc-shaped outer wall 4112, which serves as a limiting part of the guide member 410.

[0052] The shape of the positioning hole is adapted to the cross-sectional shape that is perpendicular to the centerline of the guide sleeve 411 and passes through the limiting part.

[0053] The positioning part 412 on the guide member 410 is located at the outer end of the guide sleeve 411. The size of the positioning part 412 is larger than the size of the guide sleeve 411, that is, the size of the positioning part 412 is larger than the size of the positioning hole, which provides a limit to the inward installation length of the guide member 410.

[0054] At least one positioning notch 4121 is formed on the positioning part 412, and a limiting member 430 is installed on the outer side of the positioning part 412. A positioning protrusion 431 adapted to the position of the positioning notch 4121 is formed on the limiting member 430.

[0055] The limiting member 430 is a limiting pad formed between the buffer portion 440 and the positioning portion 412, and the positioning protrusion 431 is formed on the limiting member 430 and extends toward the positioning portion 412.

[0056] In the installed state, the positioning protrusion 431 passes through the corresponding positioning notch 4121 and is inserted into the corresponding limiting hole 303 of the reinforcing member 300 to fix the position of the guide member 410.

[0057] When the guide sleeve 411 passes through the positioning hole, the position of the positioning notch 4121 on it is set at an angle to the limiting hole 303 on the reinforcing plate.

[0058] That is, only after the guide sleeve 411 has completely passed through the positioning hole and the guide member 410 has rotated can the limiting member 430 and the limiting hole 303 be docked.

[0059] A rotating neck 413 is formed between the positioning part 412 and the guide sleeve 411 to prevent interference when the guide member 410 rotates.

[0060] After the guide member 410 is installed, rotating it at a certain angle will cause the position of the limiting part on the guide member 410 to deflect and contact the reinforcing member 300, thereby fixing the position of the reinforcing member 300 in the length direction and preventing it from coming out of the positioning hole.

[0061] In some other embodiments of this application, the limiting member 430 may also be other limiting forms, such as the positioning part 412 having a first insertion hole, the reinforcing member 300 having a second insertion hole, and the limiting member 430 having a pin or other structure.

[0062] The guide member 410 is installed and rotated until the first insertion hole corresponds to the second insertion hole. The limiting member 430 connects the first insertion hole and the second insertion hole, which can also achieve the purpose of limiting the guide member 410.

[0063] refer to Figures 9-11In some embodiments of this application, the inner cylinder fixing position 210 of the inner cylinder 200 is provided with a threaded hole 211, and the connecting end 421 of the fastener 420 is formed with an external thread, and the connecting end 421 is detachably connected to the threaded hole 211.

[0064] In order to improve the forming effect of the threaded hole 211 on the inner cylinder fixing position 210 and reduce the generation of deformation, burrs, etc., at least one reinforcing part 212 is formed on the side wall of the threaded hole 211. The reinforcing part 212 is a groove-shaped structure that gradually expands away from the center of the threaded hole 211.

[0065] The number of reinforcing parts 212 can be one, or multiple parts can be evenly distributed along the circumference.

[0066] The axis of the threaded hole 211 is on the same straight line as the axis of the corresponding positioning hole, which facilitates the connection of the fastener 420 and avoids twisting.

[0067] refer to Figures 12-14 The fastener 420's connecting end 421 is the operating end 422 of the fastener 420, and a fastening washer 450 is also provided between the fastener 420 and the positioning part 412.

[0068] A buffer part 440 is also provided between the fastening gasket 450 and the positioning part 412. The buffer part 440 is made of a rubber material with a certain degree of elasticity, which can provide a certain cushioning effect.

[0069] The buffer portion 440, the fastening washer 450 and the limiting member 430 have through holes formed in the middle for the fastener 420 to pass through.

[0070] refer to Figure 15 The bottom of the inner cylinder 200 is also provided with a support member 900. The bottom of the support member 900 is connected to the bottom of the box body 100. A conformal surface 910 is formed on the support member 900 to contact and connect with the outer wall of the inner cylinder 200, which is used to further support the inner cylinder 200.

[0071] The specific fixing process of fastening component 400 will be explained in detail below: The connection method of any positioning hole on any reinforcing member 300 is similar to that of the corresponding fastening component 400, and will not be elaborated on one by one.

[0072] After the first reinforcing member 310 and the second reinforcing member 320 are fixed on the housing 100, the connecting end 421 of the fastener 420 is passed through the fastening gasket 450, the buffer part 440, the limiting member 430 and the guide member 410 in sequence, and the positioning protrusion 431 corresponds to the positioning notch 4121.

[0073] The guide 410 passes through the corresponding positioning hole until the guide sleeve 411 is completely moved into the positioning hole. The rotating neck 413 corresponds to the position of the positioning hole, and the positioning part 412 is located outside the positioning hole.

[0074] Rotate the limiting member 430 and the guide member 410 until the position of the positioning protrusion 431 on the limiting member 430 matches the limiting hole 303 on the reinforcing member 300, insert the positioning protrusion 431 into the limiting hole 303, and fix the position of the guide member 410.

[0075] Using tools such as wrenches, rotate the operating end 422 of the fastener 420 to rotate the connecting end 421 of the fastener 420 into the threaded hole 211 on the inner cylinder 200. The length of the fastener 420 is sufficient. After the connecting end 421 is rotated into the threaded hole 211, the operating end 422 presses the fastening washer 450, the buffer part 440, and the limiting part 430 onto the reinforcing part 300, thereby achieving the connection and fixation of the fastening assembly 400.

[0076] The outer wall of the housing 100 is provided with a reinforcing member 300 and a fastening component 400 to strengthen the connection between the housing 100 and the inner cylinder 200, and to change the movable connection between the inner cylinder 200 and the housing 100 into a fixed connection.

[0077] The reinforcing member 300 on the housing 100 is used to provide a fixed base for the connection of the fastening assembly 400. One end of the fastener 420 in the fastening assembly 400 is fixed to the reinforcing member 300, and the other end extends from the guide member 410 to the inner cylinder 200 and is connected to the inner cylinder 200.

[0078] The guide member 410 can improve the structural strength of the fastener 420, fix the relative position between the inner cylinder 200 and the box 100, and reduce the vibration of the inner cylinder 200; In addition, the limiting member 430 can fix the position of the guide member 410, preventing the guide member 410 from rotating or coming out of the positioning hole during the connection of the fastener 420, making the installation process of the fastener 420 simple, quick and convenient.

[0079] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0080] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
