Description

Technical Field

[0001] This utility model belongs to the field of washing equipment technology, specifically relating to a hanging device for the drain pipe of a washing equipment, and a washing equipment having the hanging device. Background Technology

[0002] In the daily use of a fully automatic washing machine, the hanging of the drain hose and the drainage operation are important aspects. When the washing machine is not in use, the drain hose is usually hung on the mounting brackets on the machine body using hooks; while the washing machine is in use, the drain hose needs to be removed from the mounting brackets to drain water.

[0003] Currently, washing machine drain hose suspension devices, such as the one disclosed in patent CN201520701065.9, employ a design where the ear clips are attached to the outer casing, and the hook is movably attached to the drain hose. The hook includes a claw head, a claw rod, a star-shaped groove, and a hook head. By pressing the claw head and claw rod together, the claw head engages with the inner wall of the drain hose. The elasticity of the star-shaped groove ensures a tight fit between the hook and the drain hose. When the claw head slides closer to the inner wall of the drain hose, and the distance between the hook head and the drain hose is greater, the drain hose can be suspended from the ear clips on the outer casing. When the claw head slides further away from the inner wall of the drain hose, and the distance between the hook head and the drain hose is smaller, the hook head is close to the outer wall of the drain hose, facilitating the insertion of the drain hose outlet into the sewer drain.

[0004] However, the aforementioned suspension device still has several shortcomings. First, the device consists of multiple components such as lugs and hooks, which not only increases the cost of the components but also requires separate installation of the lugs and hooks during assembly, significantly increasing assembly costs. Second, to prevent the hook from detaching from the lug, the hook head is designed to extend downwards at a considerable length. This means that when removing the drain pipe, the hook must be moved upwards by at least the length of the hook head, making the operation inconvenient and time-consuming. Third, the hook is fixed to the drain pipe using a snap-fit ​​method, which exerts significant pressure on the drain pipe wall at the snap-fit ​​location. This places high demands on the strength of the drain pipe wall, limiting the selection and design of the drain pipe material and making it prone to deformation or cracking of the drain pipe wall at the snap-fit ​​location.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0006] This utility model addresses the aforementioned problems in the prior art by proposing a suspension device for the drain pipe of a washing equipment, which reduces the number of components and lowers costs; it also improves the reliability of the suspension device and the efficiency of loading and unloading operations.

[0007] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0008] A suspension device for a drain pipe of a washing machine, comprising:

[0009] Hooks, which are installed on drain pipes;

[0010] The hanging opening is located on the casing of the washing equipment;

[0011] The hook has a hook head, and the hanging opening has an installation opening that matches the hook head and a locking opening that communicates with the installation opening; when the hook is in a suspended state, the hook head is locked inside the locking opening.

[0012] In some embodiments of this application, the hook has a mounting portion connected to the drain pipe and a connecting plate connected between the hook head and the mounting portion, the connecting plate being matched with the snap-fit ​​portion.

[0013] In some embodiments of this application, the width of the hook head is greater than the width of the connecting plate, and the hook head has side protrusions protruding from the connecting plate on both sides.

[0014] In some embodiments of this application, the hook head has a downward protrusion that extends outward from the connecting plate.

[0015] In some embodiments of this application, the engaging opening is located below the mounting opening; when the hook moves inward through the mounting opening, the connecting plate is aligned with the engaging opening in the vertical direction.

[0016] In some embodiments of this application, the engaging opening is located below the mounting opening; when the hook moves inward through the mounting opening, the connecting plate and the engaging opening are offset in the vertical direction.

[0017] In some embodiments of this application, the upper end of the connecting plate is flush with the upper end of the hook. The upper end of the connecting plate is also flush with the upper end of the mounting portion.

[0018] In some embodiments of this application, the height of the mounting part is greater than the height of the hook head, and the mounting part is an annular structure sleeved on the outside of the drain pipe.

[0019] In some embodiments of this application, an inwardly inclined flange is provided along the edge of the hanging opening, and the flange is inclined inward toward the center of the hanging opening.

[0020] Based on the above-described suspension device for the drain pipe of a washing machine, this application also provides a washing machine with the above-described suspension device, which reduces the number of parts, lowers costs, improves the reliability of the suspension device, and increases the efficiency of loading and unloading operations.

[0021] A washing device has a housing, a drain pipe extending from the housing, and the aforementioned suspension device.

[0022] Compared with existing technologies, the advantages and positive effects of this utility model are as follows: the hook is installed on the drain pipe, and the hanging opening is directly opened on the box body, reducing the number of independent parts and lowering the manufacturing cost of parts; at the same time, the assembly steps are reduced, lowering assembly costs. By designing the hanging opening as an installation opening and a locking opening that match the hook head, when the hook is in the suspended state, the hook head is locked inside the locking opening. When it is necessary to remove the drain pipe, the hook only needs to be moved in a specific direction to disengage the hook head from the locking opening and remove it through the installation opening, significantly shortening the operating stroke and improving the convenience and efficiency of operation. In the suspended state, the hook head is stably locked inside the locking opening, forming a stable connection structure, which can effectively prevent the hook from accidentally coming off and ensure the reliability of the drain pipe suspension during the operation of the washing equipment.

[0039] See Figures 1-5 This is an embodiment of a hanging device for a drain pipe of a washing machine proposed in this utility model. The hanging device for a drain pipe of a washing machine includes: a hook 10 and a hanging opening 21 opened on the housing 20 of the washing machine. The hook 10 is installed on the drain pipe 30. When the washing machine is not in use, the drain pipe 30 is suspended on the hanging opening 21 of the housing 20 through the hook 10. When washing, the drain pipe 30 needs to be removed so that drainage can be carried out.

[0040] See Figure 2 and Figure 3 As shown, the hook 10 has a hook head 11, and the hanging opening 21 has a mounting opening 211 that matches the hook head 11 and a locking opening 212 that communicates with the mounting opening 211; when the hook 10 is in a suspended state, the hook head 11 is locked inside the locking opening 211. The size and shape of the mounting opening 211 are matched with the hook head 11.

[0041] In this embodiment, the hook 10 is installed on the drain pipe 30, and the hanging opening 21 is directly opened on the housing 20, reducing the number of independent components and lowering the manufacturing cost of parts; at the same time, the assembly steps are reduced, lowering the assembly cost. By designing the hanging opening 21 as an installation opening 211 and a locking opening 212 that match the hook head 11, when the hook 10 is in the suspended state, the hook head 11 is locked inside the locking opening 212. When it is necessary to remove the drain pipe 30, the hook 10 only needs to be moved in a specific direction to disengage the hook head 11 from the locking opening 212 and remove it through the installation opening 211, significantly shortening the operating stroke and improving the convenience and efficiency of operation. In the suspended state, the hook head 11 is stably locked inside the locking opening 212, forming a stable connection structure, which can effectively prevent the hook 10 from accidentally coming off and ensure the reliability of the drain pipe 30 suspension during the operation of the washing equipment.

[0042] In some embodiments of this application, the hook 10 has a mounting portion 13 connected to the drain pipe 30 and a connecting plate 12 connected between the hook head 11 and the mounting portion 13. The connecting plate 12 is matched with the engaging opening portion 212; the connecting plate 12 passes through the engaging opening portion 212. The hook is connected to the drain pipe 30 through the mounting portion 13, and the connecting plate 12 passes through and matches the engaging opening portion 212, so that when the hook head 11 is engaged inside the engaging opening portion 212, not only does the hook head 11 bear the force itself, but the force during suspension is also dispersed through the cooperation of the connecting plate 12 and the engaging opening portion 212, forming a stable structure with multiple parts cooperating to bear the force, ensuring the reliability of the drain pipe suspension state. During the installation or removal of the hook 10 and the hanging opening 21, the connecting plate 12 slides inside the engaging opening portion 212, realizing the movement of the connecting plate 12 between the mounting opening portion 211 and the engaging opening portion 212.

[0043] In some embodiments of this application, the width of the mounting opening 211 is greater than the width of the engaging opening 212, and the width of the hook 11 is greater than the width of the connecting plate 12. The hook 11 has side protrusions 111 protruding from both sides of the connecting plate 12. The hanging opening 21 is opened on the rear plate or side plate of the housing 20, and the hanging opening 21 is opened vertically. The vertical dimension of the mounting opening 211 of the hanging opening 21 is slightly larger than the vertical dimension of the mounting opening 211. When installing the hook 10, the hook 11 can be aligned with the mounting opening 211 and inserted inward. Because the mounting opening 211 is relatively wide, the operation error tolerance is high and it is easy to align. Then, by moving the hook 10, the connecting plate 12 is moved from the mounting opening 211 to the engaging opening 212, and the installation is completed. Disassembly is performed in reverse. This design simplifies the operation process, reduces the installation difficulty, and improves the user experience. The side protrusions 111 on both sides of the hook head 11 protrude from the connecting plate 12. When the hook head 11 is engaged inside the engaging opening 212, the side protrusions 111 and the edge of the engaging opening 212 form a blocking structure. During the operation of the washing equipment, even if subjected to vibration or external pulling, the side protrusions 111 can effectively prevent the hook head from accidentally coming off the engaging opening 212, resulting in a more significant anti-detachment effect and ensuring the safety and stability of the drain pipe 30 suspension.

[0044] In some embodiments of this application, the hook 11 has a downwardly projecting portion 112 protruding from the connecting plate 12. When the hook 10 is engaged with the engaging portion 212 of the hanging opening 21, the downwardly projecting portion 112 can tightly engage with the lower edge of the engaging portion 212, forming an additional blocking structure. The downwardly projecting portion 112 further restricts the possibility of the hook 11 disengaging from the vertical direction, effectively preventing the hook 10 from disengaging from the hanging opening even when the washing equipment vibrates violently or the drain pipe is subjected to an upward pulling force, significantly improving the safety of the suspension device. The design of the downwardly projecting portion 112 can be adjusted in size and shape to adapt to the size and structure of the hanging opening of different models of washing equipment, increasing versatility.

[0045] In some embodiments of this application, the engaging opening 212 is located below the mounting opening 211; when the hook 11 moves inward through the mounting opening 211, the connecting plate 12 and the engaging opening 212 are aligned vertically. During installation, the user only needs to move the hook 11 horizontally inward through the mounting opening 211, and then allow it to fall naturally to achieve alignment and engagement between the connecting plate 12 and the engaging opening 212, without the need for complex angle adjustments or secondary positioning. This vertical alignment design conforms to the direction of gravity, making operation smoother and more natural, and significantly improving installation efficiency. The vertical alignment layout ensures a tighter fit between the hook 11 and the engaging opening 212 when the hook 10 is engaged, reducing unnecessary space occupation.

[0046] In other embodiments of this application, the engaging opening 212 is located below the mounting opening 211; when the hook 11 moves inward through the mounting opening 211, the connecting plate 12 and the engaging opening 212 are offset vertically. The user must first pass the hook 11 through the mounting opening 211, and then align the connecting plate 12 with the engaging opening 212 by horizontal sliding or rotation. This increases the logical flow of the operation and reduces the risk of accidental hook detachment due to misoperation. Even if the drain pipe 30 is subjected to an upward force, the hook 11 will not detach directly due to the initial offset state of the connecting plate 12 and the engaging opening 212; a specific operation must be performed to align them, thus providing additional safety.

[0047] In some embodiments of this application, the upper end of the connecting plate 12 is flush with the upper end of the hook 11. The upper end of the connecting plate 12 is also flush with the upper end of the mounting portion 13, thus creating a continuous force transmission path for the hook 10 when under stress. When the drain pipe 30 is suspended, gravity and external forces can be evenly transmitted to the mounting portion 13 through the hook 11 and the connecting plate 12, avoiding stress concentration caused by height differences, enhancing the overall structural strength of the hook 10, effectively reducing the risk of deformation or breakage due to excessive local stress, and ensuring the stability of the suspension device during use. The flush design allows for the use of uniform processing benchmarks and process parameters during the manufacturing process of the hook 10, reducing complex processing steps caused by dimensional differences, and lowering production difficulty and processing costs.

[0048] In some embodiments of this application, the height of the mounting part 13 is greater than the height of the hook head 11, and the mounting part 13 is a ring structure fitted onto the outside of the drain pipe 30. The mounting part 13 can wrap around the drain pipe to form a 360-degree enveloping connection, which can more evenly distribute the weight and tension of the drain pipe and avoid loosening or falling off due to excessive local stress. At the same time, the height of the mounting part 13 is greater than that of the hook head 11, which causes the center of gravity of the hook 10 to shift downward, forming a more stable mechanical structure in the suspended state. Even if the washing equipment vibrates during operation, it can effectively prevent the hook 10 from shaking or falling off. The ring structure of the mounting part 13 can be installed simply by fitting it onto the outside of the drain pipe, without the need for complicated snap-fitting, screw fixing, or other operations, which greatly reduces the assembly difficulty. The ring mounting part 13 is set close to the outside of the drain pipe, without occupying too much extra space, which is conducive to the compact layout inside the washing equipment.

[0049] In some embodiments of this application, an inwardly inclined flange 213 is provided along the edge of the hanging opening 21. The flange 213 helps to increase the strength of the hanging opening 21 and reduce the sharpness of the edge of the hanging opening 21, preventing the edge of the hanging opening 21 from cutting or abrading the hook 10 when it is installed. In addition, in order to prevent the box body 20 from being scratched, a film coating treatment is required on the outer surface of the box body 20. The flange 213 can effectively reduce the damage of the film coating.

[0050] In some embodiments of this application, the flange 213 is inclined inward toward the center of the hanging opening 21, providing a clear guide for the installation of the hook. When the hook approaches the hanging opening 21, the inclined surface of the flange 213 naturally guides the hook head 11 to slide inward into the hanging opening, eliminating the need for the user to manually adjust the angle, reducing installation difficulty, and significantly improving installation efficiency and accuracy. The inward inclination of the flange 213, close to the center of the hanging opening 21, forms an additional blocking structure after the hook 10 is engaged. When the drain pipe is pulled by external force or the washing equipment vibrates, the flange 213 can restrict the movement of the hook 10 from the side, preventing it from coming off the outside of the hanging opening. Flanges 213 are provided in both the mounting opening 211 and the engaging opening 212. The inclined design of the flange 213 also serves to protect the outer film of the case 20. The punching at the hanging opening 21 can damage the film on the case 20. Without the flange 213, the film would be directly damaged on the outer surface of the case 20, affecting its appearance. Alternatively, if the flange 213 is designed perpendicular to the case 20, the bending angle would be too large, also damaging the film. Therefore, the flange 213 is inclined inwards towards the center of the hanging opening 21. Preferably, the angle between the flange 213 and the plane of the hanging opening 21 is 60 degrees. This increases the strength of the punching without damaging the film on the case 20, thus preserving its appearance.

[0051] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
