Description

Technical Field

[0001] The present application relates to the technical field of clothing treatment, and particularly relates to a clothing treatment device. Background Art

[0002] Clothing treatment devices are one of the indispensable household appliances in modern families. For example, large household appliances such as drum washing machines and drum dryers usually need to go through processes such as loading, transportation, and unloading after production before finally reaching the hands of users. In this series of complex logistics processes, clothing treatment devices will inevitably suffer various impacts and vibrations. For example, accidental dropping during transportation or impacts caused by vehicle bumps. The internal structure of clothing treatment devices is complex, including the most critical clothing tub and many other components. Usually, there is no rigid connection between the clothing tub suspended in the box body and the box body and other components fixed in the box body, resulting in poor connection strength and stability. When the clothing treatment device is subjected to a large impact load, the suspended clothing tub will generate a large relative displacement under the action of inertia, and then collide with the box body or other components, leading to the risk of deformation or even damage of the tub body, which seriously affects the use performance and service life of the clothing treatment device.

[0003] In order to reduce the damage caused by external impacts during transportation to clothing treatment devices, in the prior art, a transportation protection rod passing through the back panel of the clothing treatment device and connecting to the cross beam of the front panel is usually used to protect the clothing treatment device. This transportation protection rod can absorb external impact forces during transportation to a certain extent to reduce the risk of damage to the clothing treatment device. However, this transportation protection rod will transfer the absorbed external impact force to the front panel of the clothing treatment device, thereby causing deformation of the front panel, damaging the user's overall appearance impression of the clothing treatment device, and thus reducing the user's experience.

[0004] Therefore, there is still a practical need for continuous improvement in the protection structure of clothing treatment devices during transportation. Utility Model Content

[0005] In view of this, the purpose of the embodiments of the present application is to provide an improved clothing treatment device to at least overcome one of the above disadvantages and / or other possible disadvantages not mentioned in this article.

[0006] According to the present application, a laundry treatment device is provided. The laundry treatment device includes: a laundry tub assembly, the laundry tub assembly including a laundry tub configured to accommodate laundry; a bottom structure located below the laundry tub assembly; a reinforcing structure located in front of the laundry tub assembly, the reinforcing structure being connected to the bottom structure; and at least one transport protection member, the transport protection member being configured to pass through the laundry tub assembly in an installed state and be connected to the reinforcing structure to allow protection of the laundry tub during transportation of the laundry treatment device. Thus, such an arrangement can, during transportation, for example when the laundry tub assembly is subjected to an external impact, transmit the impact force to the reinforcing structure through the transport protection member and further to the bottom structure that is not an external component of the laundry treatment device, thereby reducing the damage to the laundry tub caused by the impact force without affecting the aesthetic appearance of the laundry treatment device.

[0007] According to an optional embodiment of the present application, the laundry tub assembly includes a counterweight connected to the laundry tub, and the transport protection member is configured to pass through the counterweight in an installed state. Thus, the counterweight can serve as a fulcrum for the transport protection member to support the laundry tub assembly, further enhancing the support and protection effect of the transport protection member on the laundry tub assembly. At the same time, by utilizing the counterweight originally provided on the laundry tub assembly, there is no need to additionally add other structures to the laundry tub, which is beneficial for saving internal space.

[0008] According to an optional embodiment of the present application, the counterweight is located between the laundry tub and the reinforcing structure. Thus, the transport protection member can, for example, first pass through the counterweight from the rear of the laundry treatment device and then be connected to the reinforcing structure. In this arrangement, the impact force can be transmitted to the transport protection member through the counterweight. After the transport protection member deforms to absorb the impact force, the remaining impact force is transmitted to the front reinforcing structure. The entire force transmission path is more reasonable, the force is more dispersed, and the impact damage to a single component is reduced.

[0009] According to an optional embodiment of the present application, there is a gap between the reinforcing structure and the counterweight. Thus, even when the laundry treatment device is in normal use subsequently, for example when a drum washing machine is washing laundry, there will be no intense collision and friction between the reinforcing structure and the counterweight due to vibration, resulting in an undesired noise, without the need to disassemble the reinforcing structure.

[0010] According to an optional embodiment of the present application, the laundry treatment device includes a back panel located behind the laundry tub assembly, and the transport protection member is configured to pass through the back panel in an installed state. Thus, installers can, for example, insert and remove the transport protection member from the back panel without affecting the appearance of the front of the laundry treatment device. At the same time, the back panel can also play a role in restricting the position of the rear end of the transport protection member.

[0011] According to an alternative embodiment of the present application, the back plate is fixedly connected to the bottom structure. Thus, during the transportation of the laundry treatment device, when the back plate receives the supporting force from the transportation protection member, the supporting force can be transmitted to the bottom structure. Even if the bottom structure is deformed to a certain extent, it is still not easily noticed by the user, improving the overall aesthetics of the laundry treatment device.

[0012] According to an alternative embodiment of the present application, the back plate has a first through hole for the transportation protection member to pass through, and the laundry treatment device further includes a flexible member at least partially located in the first through hole. Thus, during the transportation of the laundry treatment device, when the transportation protection member is subjected to an impact load, the flexible member can deform within the first through hole to reduce the impact of the impact load on the back plate.

[0013] According to an alternative embodiment of the present application, the flexible member is configured as a rubber member. Thus, the rubber member has excellent flexibility and wear resistance, can effectively cover the transportation protection member and absorb the impact force, and can be used for a long time without easy aging.

[0014] According to an alternative embodiment of the present application, the flexible member is configured as an integrally formed part. Thus, the manufacturing process of this flexible member is simple and can be made by injection molding or the like to reduce the manufacturing cost.

[0015] According to an alternative embodiment of the present application, the flexible member has a first section and a second section connected to each other and a perforation passing through the first section and the second section, and the perforation has an inner diameter adapted to the outer diameter of the transportation protection member. Thus, the perforation of the flexible member is adapted to the transportation protection member, enabling the flexible member to stably cover the transportation protection member. And through the arrangement of the first section and the second section, the flexible member can better cooperate with the back plate, and the stability and support strength of the flexible member are improved through the two-section structure.

[0016] According to an alternative embodiment of the present application, the outer diameter of the first section is adapted to the inner diameter of the first through hole and is smaller than the outer diameter of the second section. Thus, this structure enables the first section to be inserted and clamped in the first through hole, while the second section cannot pass through the first through hole, thereby firmly fixing the flexible member on the back plate without falling off, and at the same time facilitating the rapid installation of the flexible member.

[0017] According to an alternative embodiment of the present application, the laundry treatment device includes two side plates connected to the back plate and opposed to each other, and the strengthening structure is respectively connected to the two side plates. Thus, without disassembling the strengthening structure, even when the laundry treatment device is in normal use subsequently, for example, when a drum washing machine is washing clothes, there will still be no intense collision and friction between the strengthening structure and the two side plates or other components inside the laundry treatment device due to vibration, resulting in undesirable noise.

[0018] According to an alternative embodiment of the present application, the laundry treating apparatus includes a front panel structure opposed to the back panel, and the reinforcing structure is configured to be shielded by the front panel structure on the front side. Thus, the reinforcing structure can be prevented from being exposed, improving the overall aesthetics of the laundry treating apparatus.

[0019] According to an alternative embodiment of the present application, the laundry tub has an opening for loading laundry, and the reinforcing structure is configured to avoid the opening on the front side. Thus, by reasonably arranging the position of the reinforcing structure, the reinforcing structure does not block the opening of the laundry tub, facilitating the user to load and unload laundry. At the same time, the size of the reinforcing structure can be shortened, saving materials and space.

[0020] According to an alternative embodiment of the present application, the reinforcing structure has ribs, and the ribs extend on the reinforcing structure along the width direction of the laundry treating apparatus. Thus, by providing ribs on the reinforcing structure, the ability of the reinforcing structure to resist deformation can be increased, improving the strength of the reinforcing structure and preventing excessive deformation under impact loads, thereby affecting the supporting function.

[0021] According to an alternative embodiment of the present application, the transportation protection member is configured as a straight rod with an outer diameter to length ratio less than 1:50. Thus, this slender rod-like structure is more likely to deform, facilitating the absorption of impact force. At the same time, it does not occupy too much internal space, making it convenient to arrange.

[0022] According to an alternative embodiment of the present application, the transportation protection member is configured as a hollow structure. Thus, compared with a solid structure, the hollow structure is more likely to deform when subjected to an impact load, thereby better absorbing the impact load and playing a better shock-absorbing role.

[0023] According to an alternative embodiment of the present application, the transportation protection member is configured to be in constrained cooperation with the reinforcing structure in the installed state. Thus, through the constrained cooperation, the transportation protection member and the reinforcing structure can be reliably fixed together, facilitating the transportation protection member to stably transfer the impact force to the reinforcing structure.

[0024] According to an alternative embodiment of the present application, the transportation protection member is configured to have a wall thickness of 0.8 mm to 1 mm. Thus, it can ensure that the transportation protection member is easily deformed while meeting the strength requirements.

[0025] According to an alternative embodiment of the present application, the transportation protection member is configured as an integrally formed part. Thus, the integrally formed process can avoid secondary processing, with higher production efficiency, and is beneficial to ensuring the coaxiality of the transportation protection member, making the force more uniform. At the same time, integral forming can also avoid stress concentration at the joints, improving the strength and service life of the transportation protection member.

[0026] According to an optional embodiment of the present application, the transport protection piece is made of stainless steel. Therefore, the transport protection piece is not only easy to process and shape, but also the stainless steel with good mechanical properties can effectively absorb the impact force and deform when subjected to impact load, thereby better protecting the clothes barrel from damage.

[0027] According to an optional embodiment of the present application, the transport protection member includes an external thread section, and the external thread section is configured to be screwed and connected with the internal thread of the reinforcement structure in the installed state. Thus, through the threaded connection, the transport protection member can be firmly fixed to the reinforcement structure and is easy to disassemble.

[0028] According to an optional embodiment of the present application, the transport protection member includes a matching section, and the matching section is configured to be loosely matched with the counterweight member in the installed state. This not only facilitates the rapid installation of the transport protection member, but also allows the counterweight member to move slightly when subjected to force, thereby further reducing the impact on the laundry tub.

[0029] According to an optional embodiment of the present application, the transport protection member includes a suspension section, which is configured to be suspended below the laundry tub in an installed state without being matched with the laundry tub assembly. Thus, direct contact between the transport protection member and the laundry tub is avoided, and the adverse effect of the impact force generated during transportation on the laundry tub is reduced.

[0030] According to an optional embodiment of the present application, the transport protection member includes a rear connection section, which is configured to pass through the first through hole of the back plate in the installed state and be surrounded by the flexible member. Thus, by arranging the rear connection section at the rear end of the transport protection member, the transport protection member and the back plate can be stably connected; and by arranging the flexible member between the two, a buffering effect can be played, so as to avoid the rigid connection between the rear connection section of the transport protection member and the back plate, which causes the impact force generated during transportation to be directly transmitted to the back plate, thereby avoiding undesirable deformation of the back plate.

[0031] According to an optional embodiment of the present application, the transport protection member includes an end section, and the end section has an operating portion for the operator to screw. Therefore, an operating portion that is convenient for applying force, such as a handle, a nut, a flange, etc., is provided at the end, which can facilitate the operator to quickly tighten or disassemble the transport protection member, thereby improving the work efficiency.

[0032] According to an optional embodiment of the present application, the counterweight has a second through hole for the transport protection member to pass through, and the difference between the inner diameter of the second through hole and the outer diameter of the matching section is in the range of 6 mm to 14 mm. Thus, a suitable gap is left between the counterweight and the transport protection member, which not only facilitates the rapid installation of the transport protection member, but also allows the counterweight to move slightly when subjected to force, thereby further reducing the impact on the laundry tub.

[0033] According to an alternative embodiment of the present application, the end segment further includes a flange portion configured to press against the flexible member in the installed state. Thus, by providing a flange portion at the end of the transportation protection member and making it abut against the flexible member, the flexible member can be squeezed when the transportation protection member is tightened, causing the flexible member to deform and block the first through hole, improving the fitting strength between the flexible member, the transportation protection member, and the back plate, and avoiding shaking and loosening.

[0034] According to an alternative embodiment of the present application, the fitting segment, the suspension segment, and the rear connection segment are sequentially connected to each other. Thus, by sequentially arranging the three segments of the fitting segment, the suspension segment, and the rear connection segment in the threading direction of the transportation protection member, a favorable force transmission path can be formed to sequentially achieve the fitting connection between the transportation protection member, the strengthening structure, the counterweight member, and the back plate. On the one hand, this arrangement conforms to the spatial structure inside the laundry treatment device. On the other hand, when the laundry tub assembly is impacted, the impact load can be sequentially transmitted along the fitting segment, the suspension segment, and the rear connection segment and gradually attenuated, thereby protecting the laundry tub from damage and also avoiding undesired deformation of the back plate.

[0035] According to an alternative embodiment of the present application, the length of the suspension segment occupies at least 3 / 4 of the total length of the transportation protection member. Thus, most of the laundry tub is located above the suspension segment of the transportation protection member. When the laundry tub assembly is impacted, the part that has a force interaction with the transportation protection member is basically limited to the counterweight member of the laundry tub assembly. The laundry tub and even the back plate are basically not affected by the impact force due to the existence of the relatively long suspension segment, thereby avoiding deformation of the laundry tub and even the back plate.

[0036] According to an alternative embodiment of the present application, the laundry treatment device includes a connecting member configured to fixedly connect the counterweight member to the laundry tub. The extending direction of the connecting member is parallel to the longitudinal axis of the transportation protection member. Along the extending direction of the longitudinal axis, the projection of the connecting member on the longitudinal axis at least partially overlaps with the fitting segment or the distance therebetween is less than 10 mm. Thus, by the projection of the connecting member on the longitudinal axis of the transportation protection member being covered by the fitting segment of the transportation protection member, or the two partially overlapping or having a short distance, when subjected to an impact load, damage to the connecting part of the connecting member due to excessive shear force can be avoided.

[0037] According to an alternative embodiment of the present application, the transportation protection member is configured such that its longitudinal axis is parallel to the central axis of the laundry tub in the installed state. The laundry treatment device includes two such transportation protection members, and the two transportation protection members are respectively located on both sides of the vertical plane where the central axis of the laundry tub is located. Thus, by arranging the transportation protection members on both sides of the laundry tub, the impact loads received by the transportation protection members are relatively balanced, and the protection effect is better.

[0038] According to an alternative embodiment of the present application, the distance between the two transportation protection members is at least greater than 2 / 3 of the outer diameter of the laundry tub. This ensures the support span of the transportation protection members for the laundry tub and achieves a more comprehensive protection effect.

[0039] According to an alternative embodiment of the present application, the laundry tub is configured not to have a structure for the transportation protection member to pass through. Thus, there is no need to specifically provide holes or lugs on the laundry tub for the transportation protection member to pass through. On the one hand, this avoids the impact force on the transportation protection member directly acting on the easily damaged laundry tub usually made of plastic. On the other hand, it also avoids reserving assembly holes or lugs on the laundry tub, which takes up internal space and is beneficial to improving space utilization.

Detailed implementation manners

[0053] In order to make the technical problems to be solved, technical solutions and beneficial technical effects of the present application clearer, the present application will be further described in detail below in conjunction with the drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the protection scope of the present application, and each embodiment may share the same view or multiple views for description, but all the features appearing in the same view cannot be interpreted as the features that must be possessed by an embodiment.

[0054] Before starting the description, it should be pointed out that for convenience, azimuth terms or direction terms may be used in this article for description. These azimuth terms or direction terms are relative to the normal use state of the clothing processing device (such as a drum washing machine), and those skilled in the art can clearly understand this from the description of the present application without any confusion. In this case, the azimuth terms and direction terms should not be simply interpreted as the azimuth or direction in any state. That is to say, the azimuth or position relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "longitudinal", "transverse", "high", "positive", "back", etc. in the description of the present application is based on the azimuth or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific azimuth, be constructed and operated in a specific azimuth, and therefore cannot be understood as a limitation to the present application.

[0055] For ease of understanding, the description made in the background art section of the present application can be traced back or recalled here. One object of the present application is to provide an improved laundry treatment apparatus, which comprises: a laundry tub assembly including a laundry tub configured to accommodate laundry; a bottom structure located below the laundry tub assembly; a reinforcing structure located in front of the laundry tub assembly and connected to the bottom structure; and at least one transportation protection member configured to pass through the laundry tub assembly in the installed state and be connected to the reinforcing structure to allow protection of the laundry tub during transportation of the laundry treatment apparatus. Thus, such an arrangement can, during transportation, for example when the laundry tub assembly is subjected to a downward impact force, transmit the impact force to the reinforcing structure through the transportation protection member and further transmit it to the bottom structure which does not belong to the appearance components of the laundry treatment apparatus, thereby reducing the damage to the laundry tub caused by the impact force without affecting the aesthetic appearance of the laundry treatment apparatus.

[0056] Exemplary embodiments of the present application will be described below with reference to the accompanying drawings.

[0057] Figure 1 A perspective view of a laundry treatment apparatus 1000 according to an exemplary embodiment of the present application is shown. The laundry treatment apparatus 1000 is exemplary configured as a drum washing machine or other laundry treatment apparatus that needs to protect its laundry tub, such as a drum dryer or a drum washer-dryer. Figure 1 A schematic illustration of the xyz coordinate system of the laundry treatment apparatus 1000 is shown, where x represents the width direction of the laundry treatment apparatus 1000, y represents the height direction of the laundry treatment apparatus 1000, and z represents the depth direction of the laundry treatment apparatus 1000. For clarity, in the subsequent drawings, this xyz coordinate system is basically referred to for display and description.

[0058] Figure 2 Shows Figure 1 A perspective view of some components of the laundry treatment apparatus 1000 shown; Figure 3 Shows Figure 1 A perspective view of some components of the laundry treatment apparatus 1000 shown; Figure 4 Shows Figure 3 An exploded view of some components of the laundry treatment apparatus 1000 shown.

[0059] As Figure 1 Combined with Figure 2 、 Figure 3 And Figure 4As shown, the laundry treatment device 1000 includes a laundry tub assembly 900, a bottom structure 800, a reinforcement structure 700, and at least one transportation protection member 600. Herein, the laundry tub assembly 900 includes a laundry tub 910 for accommodating laundry. The laundry tub assembly 900 is located above the bottom structure 800 and has a central axis L0. When the laundry treatment device 1000 is operating, for example, the inner tub of the laundry tub 910 can rotate about the central axis L0. The reinforcement structure 700 is located in front of the laundry tub assembly 900 and is connected to the bottom structure 800. The transportation protection member 600 passes through the laundry tub assembly 900 in the installed state and is connected to the reinforcement structure 700, and is used to protect the laundry tub 910 from impact damage during the transportation of the laundry treatment device 1000.

[0060] Figure 1 The outer shell members that can be directly seen by the user of the laundry treatment device 1000 are also schematically shown, specifically including a rear panel 500 located behind the laundry tub assembly 900, a front panel structure 300 opposite to the rear panel 500, and two side panels 400 connected to the rear panel 500 and opposite to each other ( Figure 1 The rear panel 500 is not directly shown due to the angle and only one of the side panels 400 is shown). Figure 2 Except for the rear panel 500, other outer shell members are not shown, so that the laundry tub assembly 900 located inside the outer shell members can be clearly seen. As Figure 2 shown, in addition to the laundry tub 910, the laundry tub assembly 900 further includes a counterweight member 920 connected to the laundry tub 910. The counterweight member 920 can be formed by pouring high-strength concrete, for example, and its mass distribution is optimized to provide a balancing moment when the inner tub of the laundry tub 910 rotates at a high speed, and reduce the vibration of the laundry treatment device 1000. Optionally, the counterweight member 920 can also be made of metal. Herein, the counterweight member 920 is located between the laundry tub 910 and the reinforcement structure 700. In a preferred embodiment, the transportation protection member 600 passes through the rear panel 500, the counterweight member 920, and the reinforcement structure 700 in sequence in the installed state. As Figure 2 can be seen, the reinforcement structure 700 has ribs 710, and the ribs 710 extend over the entire reinforcement structure 700 in the width direction x of the laundry treatment device 1000. As Figure 2 can also be seen, the laundry tub 910 has an opening 911 for loading laundry, and the reinforcement structure 700 is configured to avoid the opening 911 on the front side.

[0061] Figure 3 and Figure 4 The bottom structure 800 is exemplarily shown. The bottom structure 800 is preferably configured as a galvanized sheet and has a base below it when placed in a transportation package. The rear panel 500 is fixedly connected to the bottom structure 800, for example, by riveting. For clarity, Figure 3 and Figure 4Only one side plate 400 is shown. The strengthening structure 700 is preferably connected to the two side plates 400 respectively, for example, by riveting.

[0062] Figure 3 and Figure 4 Only the front panel member of the front panel structure 300 is shown, thereby exposing the strengthening structure 700. In one embodiment, the front panel structure 300 can be configured as a front panel integral that directly extends to the bottom structure 800 (see also Figure 1 ). In Figure 3 and Figure 4 In the illustrated embodiment, the front panel structure 300 can include a front panel member independent of each other and other parts extending to the bottom structure 800 (such as a maintenance door, etc.). In both of these embodiments, the strengthening structure 700 is blocked by the front panel structure 300 on the front side and cannot be seen by the user.

[0063] From Figure 4 it can be seen that the back panel 500 has a first through hole 501 for the transportation protection member 600 to pass through, and the laundry treatment device 1000 further includes a flexible member 200 at least partially located in the first through hole 501. In combination with what will be described next Figure 9, for clarity, it is shown in the form that the flexible member 200 is attached to the transportation protection member 600. In a preferred embodiment, in the installed state, one end of the transportation protection member 600 (shown as the front end in the figure) is constrainedly engaged (e.g., screwed connection) with the strengthening structure 700, and the other end (shown as the rear end in the figure) is unconstrainedly engaged (e.g., loose connection) with the back plate 500, and preferably penetrates into the first through hole 501 of the back plate 500 with the flexible member 200 as shown in the figure. In this case, when the laundry treatment device 1000 is subjected to an external impact force during transportation, only the front end of the transportation protection member 600 is fastened to the laundry treatment device 1000 (more precisely, the strengthening structure 700), while the rear end is movable to a certain extent relative to the laundry treatment device 1000 (more precisely, the back plate 500), especially movable relative to the laundry treatment device 1000 with shock absorption through the flexible member 200. Thus, on the one hand, a firm support is provided to the transportation protection member 600 during transportation, so that when the transportation protection member 600 bears the impact force from the laundry treatment device 1000 (especially the counterweight member 920 of the laundry tub assembly 900), part of the impact force can be directly transmitted to the strengthening structure 700, and then transmitted to the bottom structure 800. Usually, shock-absorbing foam for packaging is also provided at the bottom structure 800 to absorb the impact energy, so as to avoid transmitting all the impact force to the back plate 500. On the other hand, since the transportation protection member 600 and the back plate 500 are movably connected, and the flexible member 200 is used to realize the flexible connection between the transportation protection member 600 and the back plate 500, the back plate 500 only bears a small part of the impact force during the transportation of the laundry treatment device 1000, and to a certain extent, prevents the back plate 500 from deforming. This is because although the back plate 500 is not directly facing the user, it still belongs to the appearance component of the overall laundry treatment device 1000. If the back plate 500 shows obvious deformation, it will affect the overall aesthetics of the laundry treatment device 1000. Since the transportation protection member 600 mainly bears the impact force vertically downward during transportation, if both ends of the transportation protection member 600 are subjected to constrained engagement or rigid connection (such as screwed connections with both the strengthening structure 700 and the back plate 500), then it is very likely that the transportation protection member 600 will be overconstrained due to assembly tolerances, and may break under the action of the impact force. Therefore, in a preferred embodiment, one end of the transportation protection member 600 (the end connected to the strengthening structure 700) is constrained and transmits the impact force, while the other end (the end connected to the back plate 500) maintains a certain degree of freedom.

[0064] Figure 5 shows Figure 1 a front view of some components of the laundry treatment device shown.

[0065] As Figure 5 combined with Figure 4As shown, the laundry treating apparatus 1000 includes two transportation protection members 600, namely a first transportation protection member 601 and a second transportation protection member 602, which are respectively located on both sides of the vertical plane where the central axis L0 of the laundry tub 910 is located. The distance between the first transportation protection member 601 and the second transportation protection member 602 is at least greater than two-thirds of the outer diameter of the laundry tub 910.

[0066] Figure 6 shows a cross-sectional view taken along the Figure 5 A-A cutting plane; Figure 7 shows another embodiment different from Figure 6 that.

[0067] As Figure 5 shown, the laundry treating apparatus 1000 includes a plurality of connectors 100, such as screws, configured to fixedly connect the counterweight member 920 to the laundry tub 910. Figure 6 and Figure 7 both show two of the connectors 100. From the Figure 6 angle, the extending directions of these two connectors 100 are both parallel to the longitudinal axis L1 of the transportation protection member 600. Along the extending direction of the longitudinal axis L1, the projections of these two connectors 100 on the longitudinal axis L1 at least partially overlap with the mating section 620 of the transportation protection member 600 (more precisely, within the range of the mating section 620). Combining Figure 5 , the connectors 100 may also be located in a vertical plane different from the vertical plane where the transportation protection member 600 is located (i.e., the Figure 6 yz plane shown). Therefore, as long as the projection of the connector 100 on the longitudinal axis L1 of the transportation protection member 600 (based on the Figure 5 arrangement projects the connector 100 obliquely onto the longitudinal axis L1) at least partially overlaps or has a small spacing with the mating section 620 of the transportation protection member 600 along the extending direction of the longitudinal axis L1 (also referring to Figure 7 to be described next), then even if the counterweight member 920 transmits the force received from the mating section 620 of the transportation protection member 600 to the connector 100, the force transmitted to the connector 100 is basically still an axial force, thereby reducing the risk that the connector 100 breaks due to excessive shear force.

[0068] In Figure 7 the shown embodiment, along the extending direction of the longitudinal axis L1 of the transportation protection member 600, the spacing between the projections of the two connectors 100 on the longitudinal axis L1 of the transportation protection member 600 and the mating section 620 of the transportation protection member 600 is less than 10 mm, thereby also reducing the risk that the connector 100 breaks due to excessive shear force. On the other hand, Figure 7The illustrated embodiment can, to a certain extent, broaden the usable space inside the laundry treating apparatus 1000, thereby avoiding other components inside the laundry treating apparatus 1000. In combination with Figure 5 , connectors 100 are respectively provided on both sides of the vertical plane where the longitudinal axis L1 of the transport protection member 600 (for example, each of the first transport protection member 601 and the second transport protection member 602) is located, thereby achieving moment balance and further reducing the risk of the connectors 100 breaking due to excessive shear force.

[0069] From Figure 6 and Figure 7 it can be seen that the longitudinal axis L1 of the transport protection member 600 (here the first transport protection member 601) is parallel to the central axis L0 of the laundry tub 910. From Figure 6 and Figure 7 it can also be seen that there is a gap, such as 23.5 mm, between the reinforcing structure 700 and the counterweight member 920.

[0070] Figure 8 Shows Figure 6 A partial enlarged view of B of Figure 6 . The counterweight member 920 has a second through hole 921 for the transport protection member 600 to pass through, and the difference between the inner diameter d2 of the second through hole 921 and the outer diameter d1 of the fitting section 620 is in the range of 6 mm to 14 mm.

[0071] Figure 9 Shows a perspective view of the transport protection member 600 of the laundry treating apparatus 1000 according to an exemplary embodiment of the present application.

[0072] As Figure 9 Schematically shown, the transport protection member 600 is configured as a straight rod with a ratio of outer diameter to length less than 1:50. For example, the overall outer diameter d1 of the straight rod is about 12 mm and the total length M is about 605 mm. Preferably, the transport protection member 600 is configured as an integrally formed part and is especially made of stainless steel. Further preferably, the transport protection member 600 is configured as a hollow structure and especially has a wall thickness of 0.8 mm to 1 mm.

[0073] As Figure 9 In combination with Figure 6As shown, according to the direction of the transport protection member 600, the transport protection member 600 includes an external thread section 610, a matching section 620, a suspension section 630, a rear connection section 640 and an end section 650, wherein the external thread section 610 is screwed and connected with the internal thread of the reinforcement structure 700, the matching section 620 is clearance-matched with the counterweight 920, the suspension section 630 is suspended below the clothing barrel 910 and is not matched with the clothing barrel assembly 900, the rear connection section 640 passes through the first through hole 501 of the back plate 500 and is surrounded by the flexible member 200, and the end section 650 has an operating portion 651 (e.g., a hexagonal contour portion) for the operator to screw. Preferably, the end section 650 also includes a flange portion 652 configured to press against the flexible member 200 in the installed state. Further preferably, the matching section 620, the suspension section 630 and the rear connection section 640 are connected to each other in sequence as shown in the figure, wherein the length of the suspension section 630 preferably occupies more than 3 / 4 of the total length M of the transport protection member 600. For example, the total length M is about 605 mm, and the length of the suspension section 630 is about 500 mm.

[0074] Figure 9 The flexible member 200 is shown attached to the transport protection member 600. Figure 9 It can be seen that the flexible member 200 has a first section 201 and a second section 202 connected to each other and a through hole running through the first section 201 and the second section 202, the through hole having an inner diameter adapted to the outer diameter d1 of the transport protection member 600, and the transport protection member 600 is located in the through hole of the flexible member 200 in the installed state, for example, in a transition fit manner. Figure 4 The outer diameter of the first section 201 matches the inner diameter of the first through hole 501 of the back plate 500, but the outer diameter of the first section 201 is smaller than the outer diameter of the second section 202. The flexible member 200 is preferably constructed as an integrally formed member and is preferably made of rubber material.

[0075] Figure 10 A simplified schematic diagram of an exemplary embodiment according to the present application is shown in the yz plane. Figure 10 In the preferred embodiment shown, except for the counterweight 920 of the laundry tub assembly 900, other parts of the laundry tub assembly 900 (especially the laundry tub 910) itself do not have a structure specifically for the transportation protection member 600 to pass through. Figure 10 The reinforcing structure 700, the weight 920, the back plate 500, the transport protection member 600 disposed therebetween, and the bottom structure 800 respectively connecting the reinforcing structure 700 and the back plate 500 are schematically shown with solid lines before the laundry treatment device 1000 is transported; the reinforcing structure 700 after the laundry treatment device 1000 is impacted is schematically shown with dotted lines in an exaggerated form, and the transport protection member 600 after the laundry treatment device 1000 is impacted is schematically shown with dotted lines in an exaggerated form. Figure 10It can be seen that the transportation protection member 600 is equivalent to a beam simply supported at both ends. According to the principle of moment balance, the magnitude of the reaction force at a certain point is inversely proportional to the distance from this point to the acting point of the acting force. During the transportation of the laundry treatment apparatus 1000, when it is subjected to an external impact, since the laundry tub assembly 900 is suspended inside the laundry treatment apparatus 1000 and is usually subjected to a strong impact, at this time, the closer the acting point of the impact force is to one side of the reinforcing plate 700, the greater the reaction force generated at this place, and the smaller the reaction force generated at the far end (i.e., the side of the back plate 500) (especially when the flexible member 200 also absorbs part of the impact additionally). Thus, the back plate 500 basically does not deform. Even if the reinforcing structure 700 generates a small amount of deformation, it is not noticed by the user because it is located inside the housing member of the laundry treatment apparatus 1000. In Figure 10 In [description], the transportation protection member 600 shown by the dotted line can be conveniently removed, for example, by screwing, after the laundry treatment apparatus 1000 arrives at the destination (such as the user's residence) during transportation, thereby not affecting the normal use of the laundry treatment apparatus 1000.

The feature examples provided in the disclosure of the present application are for illustrative purposes only and not for limitation, unless otherwise expressly stated. In specific implementations, multiple features can be combined with each other according to actual needs and when technically feasible. Various substitutions, changes, and modifications can also be conceived without departing from the spirit and scope of the present application.
