[0057] In the present invention, the pipeline and circuit between two relatively moving components are installed through a retractable pipeline arrangement structure, so that the pipeline and circuit can move along with the components while being better protected, reducing the impact of movement on the pipeline and improving stability. It can also achieve pipeline separation to improve safety, and this installation structure is easy to install, compact in structure, can be used in narrow spaces, and has a wider application range. The present invention will be introduced in detail below with reference to specific embodiments.

[0058] As Figure 1 , Figure 2 shown, the present invention provides a retractable pipeline arrangement structure, which is arranged between a first component and a second component that can move relative to each other, and is used to install the connecting pipeline and / or circuit between the first component and the second component, such as a water inlet pipeline, a drainage pipeline, a power supply line, a control line, etc. The retractable pipeline arrangement structure includes:

[0059] A first mounting seat, including a first fixed seat and a first rotating seat, and the first rotating seat is connected to the first fixed seat;

[0060] A second mounting seat, including a second fixed seat and a second rotating seat, and the second rotating seat is connected to the second fixed seat;

[0061] A circuit installation structure, including a connecting rod structure, and both ends of the connecting rod structure are respectively connected to the first rotating seat and the second rotating seat;

[0062] A pipeline installation structure, including:

[0063] A first telescopic structure, telescopically arranged between the first rotating seat and the second rotating seat, and an installation space for installing a drainage pipe is formed inside it,

[0064] A second telescopic structure, telescopically arranged between the first rotating seat and the second rotating seat, and the outer peripheral wall thereof is used to support the water inlet pipe

[0065] A plurality of installation positions for installing the second telescopic structure are correspondingly arranged on the first rotating seat and the second rotating seat.

[0066] As Figure 1 shown, in this embodiment, the first mounting seat 10 includes:

[0067] The first fixing base 11 is used for fixedly connecting with the first component. A fixed connection part is arranged on the first fixing base 11. Preferably, the fixed connection part is configured as a plate-like structure and includes a plurality of through holes, and it can be fixedly connected to the first component through connecting parts such as bolts. A rotating connection part is arranged on the fixed connection part for hinged connection with the first rotating base 12.

[0068] Preferably, as Figure 11 shown, a first pipeline joint 111 is arranged on the first fixing base 11 for communicating with the pipeline. The first pipeline joint 111 can be arranged on the fixed connection part, or a support plate is arranged on the fixed connection part, and the first pipeline joint 111 is arranged on the support plate. Through the first pipeline joint 111, the connection of the pipeline can be realized, so that during the movement of the overall installation structure, the first pipeline joint 111 can move synchronously, avoiding loosening at the joint during the movement and affecting the sealing performance. Further, one or more first pipeline joints 111 can be arranged, and the pipe diameters of the plurality of first pipeline joints 111 can be different to realize the installation of various different pipelines.

[0069] The first mounting base 10 further includes a first rotating base 12. The first rotating base 12 is hinged to the first fixing base 11. The first rotating base 12 includes a main body part, and the main body part is configured as a narrow and long plate-like structure. A first rotating base 121 that cooperates with the rotating connection part on the first fixing base 11 is arranged on one side thereof. Preferably, a rib plate is arranged between the first rotating base 121 and the main body part to increase the strength of the main body part. The first rotating base 121 and the rotating connection part are rotationally connected through a rotating shaft, so that the first rotating base 12 can rotate relative to the first fixing base 11. Preferably, in this embodiment, two first fixing bases 11 are arranged, and the two first fixing bases 11 are arranged at a certain distance apart and are arranged vertically up and down; correspondingly, two first rotating bases 121 are arranged on the first rotating base 12, and the two first fixing bases 11 and the two first rotating bases 121 form two pairs of rotational fits in one-to-one correspondence. Further, the two pairs of rotational fits are connected by a first connecting shaft 13 for convenient assembly and at the same time can also improve the overall strength and stability. Similarly, two second fixing bases 21 are also arranged, and two pairs of rotational fits are formed between the two second fixing bases 21 and the second rotating base 22 and are connected by a second connecting shaft 23.

[0070] As Figure 6 、 Figure 7As shown, the first rotating seat 12 further includes: a first hinged portion 122 connected to the link structure 30. The first hinged portion 122 is hinged to one end of the link structure 30. The first hinged portion 122 is at the upper end of the main body portion and preferably includes two support portions. The two support portions are arranged oppositely and spaced apart by a certain distance. Hinge holes are provided at the ends of the two support portions, and the axes of the two hinge holes are collinear. The end of the link structure 30 extends between the two support portions and is passed through the two hinge holes and the link structure 30 by a pin shaft or other structures to achieve the hinge. It is easy to think that only one support portion can also be provided to achieve the hinge with the link structure 30.

[0071] The first rotating seat 12 further includes: a first fixing portion 123 connected to the first part 41. The first fixing portion 123 is provided at the lower end of the main body portion. A through hole communicating with the installation space is provided on the first fixing portion 123, and a water pipe or a line can pass through the through hole and enter the installation space.

[0072] As Figure 8 、 Figure 9 shown, a second telescopic structure connection hole 124 is provided on the first rotating seat 12. Preferably, along its extending direction, a plurality of second telescopic structure connection holes 124 can be provided so that a plurality of second telescopic structures 60 can be installed, or the installation position can be adjusted.

[0073] The second mounting seat 20 includes:

[0074] A second fixed seat 21 for fixedly connecting to the second component;

[0075] A second rotating seat 22. The second rotating seat 22 is hinged to the second fixed seat 21.

[0076] The second rotating seat 22 has the same structure as the first rotating seat 12 and includes: a main body portion, a second hinged portion 222 connected to the link structure 30 is provided on the main body, and the second hinged portion 222 is hinged to one end of the link structure 30; and / or, a second fixing portion 223 connected to the second part 42, and a through hole communicating with the installation space is provided on the second fixing portion 223. A second rotating base 221 is further provided on the main body portion, and the second rotating base 221 is used for rotatably connecting to the second fixed seat 21.

[0077] In this embodiment, the structure of the second fixed seat 21 is the same as that of the first fixed seat 11. A second pipeline joint 211 is provided on the second fixed seat 21 for connecting to a pipeline. Or, part of the structure of the second fixed seat 21 can be partially different from that of the first fixed seat 11 according to the requirements of its cooperation with the second component, but the functions of the corresponding parts are the same; the second rotating seat 22 has the same structure as the first rotating seat 12, and the specific structure of the second mounting seat 20 will not be described in detail here.

[0078] Specifically, asFigure 2 , Figure 3 As shown in Figure 3 , the connecting rod structure 30 includes:

[0079] A first connecting rod 31, the first end of the first connecting rod 31 is hinged to the first mounting seat 10;

[0080] A second connecting rod 32, the first end of the second connecting rod 32 is hinged to the second end of the first connecting rod 31;

[0081] A third connecting rod 33, the first end of the third connecting rod 33 is hinged to the second end of the second connecting rod 32, and the second end of the third connecting rod 33 is hinged to the second mounting seat 20; Preferably, the first connecting rod 31, the second connecting rod 32 and the third connecting rod 33 are connected by a rotating shaft. Hinge holes are provided at both ends of the first connecting rod 31, the second connecting rod 32 and the third connecting rod 33. The hinge between the two connecting rods is realized by passing a rotating shaft, a connecting pin and other structures through the two hinge holes. The first connecting rod 31 and the third connecting rod 33 are hinged at both ends of the second connecting rod 32. An included angle is formed between the first connecting rod 31 and the third connecting rod 33 and the second connecting rod 32, and the size of the included angle can be changed with the relative movement of the first mounting seat 10 and the second mounting seat 20, so as to realize the telescopic of the overall length of the connecting rod structure 30. Preferably, in other embodiments, the connecting rod structure 30 can also be provided with more connecting rods, such as four connecting rods, five connecting rods, etc., which can be set according to needs.

[0082] Alternatively, a structure similar to the connecting rod structure 30 can also be used to replace it. For example, a drag chain structure can be used to replace the connecting rod structure 30, and a communication cavity for arranging pipelines or lines is formed inside the drag chain structure.

[0083] In this embodiment, a fixing structure is provided on the first connecting rod 31 and / or the second connecting rod 32 and / or the third connecting rod 33. The fixing structure is used to fix pipelines and / or lines. Preferably, the fixing structure is provided on all three connecting rods at the same time to make the fixing of pipelines and / or lines more reliable, and the pipelines and / or lines can be arranged along the connecting rod structure 30.

[0084] Preferably, the fixing structure includes a first clamping structure for fixing lines and / or a second clamping structure for fixing pipelines. In this embodiment, the first clamping structure and the second clamping structure are provided at the same time.

[0085] Furthermore, the first link 31, the second link 32, and the third link 33 are configured as plate-like structures. The link structure 30 formed by connecting the three includes a first mounting surface and a second mounting surface. A first clamping structure is formed on the first mounting surface for fixing lines, such as power supply and control lines, etc.; a second clamping structure is formed on the second mounting surface for fixing pipelines, such as water inlet and drainage pipelines, etc. The first clamping structure and the second clamping structure are respectively formed on two surfaces of the link structure 30 to separate the water circuit and the electric circuit and avoid mutual influence between water and electricity.

[0086] Such as Figure 3 As shown, the first clamping structure preferably includes a strong electricity clamping structure 301 for fixing the power supply line and a weak electricity clamping structure 302 for fixing the control line to achieve the separation of strong electricity and weak electricity, making the line layout neater and also avoiding mutual interference between strong electricity and weak electricity.

[0087] The second clamping structure includes a water pipe slot for clamping the water pipe. Preferably, water pipe slots are simultaneously provided on the first link 31, the second link 32, and the third link 33, so that the water pipe can be arranged along the link structure 30. In this embodiment, an anti-freezing and cracking structure 34 is provided on the water circuit. The anti-freezing and cracking structure 34 is connected to the water circuit as a part of the water circuit. Preferably, the second link 32 is located at the low point of the link structure 30, and the anti-freezing and cracking structure 34 is provided on the second connecting rod. The water pipe is divided into two parts, which are respectively clamped on the first link 31 and the second link 32, and then connected to the anti-freezing and cracking structure 34 at the same time.

[0088] When the anti-freezing and cracking structure 34 is provided, there is no need to provide a water pipe slot on the second link 32. Furthermore, in order to cooperate with the installation of the anti-freezing and cracking structure 34, a first water pipe slot is provided at a position close to the first end of the first link 31, and a second water pipe slot 303 is provided at a position close to its second end (close to the second link 32). The anti-freezing and cracking structure 34 is located on the lower side of the second link 32, and the second water pipe slot 303 protrudes downward from the first link 31 to facilitate the pipeline to pass through the second water pipe slot 303 and connect to the anti-freezing and cracking structure 34. In this embodiment, the third link 33 and the first link 31 form a symmetrical structure and are symmetrically arranged at both ends of the second link 32.

[0089] Such as Figure 4 、 Figure 5 As shown, preferably, the anti-freezing and cracking structure 34 includes a water flow channel 341, which is communicated with the water circuit for water to flow through. Preferably, the water flow channel 341 is a tubular structure arranged along the extension direction of the second link 32, and its two ends are respectively used for communicating with the pipeline.

[0090] The anti-freezing structure further includes an air cavity 342, which is located above the water flow channel 341 and is connected to the water flow channel 341 through a communication hole 343. Preferably, the aperture of the communication hole 343 is small. When there is water flowing in the water flow channel 341, the water flow will block the communication hole 343, and since there is air in the exhaust cavity 342, water will not enter the exhaust cavity 342. When the ambient temperature drops, the air in the air cavity 342 shrinks, and the water in the water flow channel 341 freezes and expands in volume. A part of the water will enter the air cavity 342 through the communication hole 343, thus preventing the pipeline from bursting due to the expansion of the frozen water. Since the anti-freezing structure 34 is located at the lowest point of the pipeline, a small amount of water remaining in the pipeline will remain in the water flow channel 341 of the anti-freezing structure 34, preventing the entire pipeline from being affected by freezing.

[0091] In this embodiment, as Figure 6 shown, the first telescopic structure 40 is configured as a sleeve assembly, that is, both the first part 41 and the second part 42 are configured as cylindrical structures, sleeved together and capable of sliding relative to each other. Among them, the first part 41 and the second part 42 can be integrally formed with the first mounting seat 10 and the second mounting seat 20 respectively to simplify the assembly process. Preferably, in this embodiment, the first part 41 is formed separately from the first rotating seat 12 and is detachably connected. For example, an internal thread can be provided in the through hole of the first fixing part 123, an external thread can be provided at the first end of the first part 41, and the first part 41 is connected by a thread. Alternatively, a flange structure can also be provided at the first end of the first part 41 and connected by a flange and a connecting member. The second part 42 and the second rotating seat 22 are integrally formed.

[0092] Furthermore, the radial dimension of the first part 41 is smaller than that of the second part 42. The first part 41 extends into the second part 42, and a guiding structure is provided along the axial direction on the first part 41 and the second part 42. For example, a partial circular ring protrusion is provided on the outer peripheral wall of the second end of the first part 41 to form a limiting guiding protrusion 410. Correspondingly, a partial circular ring-shaped groove that matches the shape of the limiting guiding protrusion 410 is provided on the inner peripheral wall of the second part 42 and extends along the axial direction to form a limiting guiding groove, and the limiting guiding groove is closed at the end of the second part, so that the cooperation of the limiting guiding protrusion 410 and the limiting guiding groove can limit and guide the sliding of the first part 41 and the second part 42 in the axial direction and limit them in the circumferential direction.

[0093] Alternatively, a groove is formed along the axial direction on the outer peripheral wall of the first part 41, and a protrusion is provided along the axial direction on the inner peripheral wall of the corresponding second part 42. The protrusion extends into the groove and can slide relative to each other to guide the sliding of the first part 41 and the second part 42. Preferably, two grooves and two protrusions are provided. It is easy to think that a protrusion can also be provided on the outer peripheral wall of the first part 41 and a groove can be provided on the inner peripheral wall of the second part 42.

[0094] Alternatively, two or more first telescopic structures 40 can be provided simultaneously to cooperate with the installation of different pipelines or lines. For example, two first telescopic structures 40 can be provided, and the two first telescopic structures 40 can adopt different structures or the same structure. Of course, more first telescopic structures 40 can also be provided according to needs.

[0095] Preferably, as Figure 1 、 Figure 2 shown, a telescopic pipe 50 is further included. The telescopic pipe 50 is arranged inside the first telescopic structure 40. The end of the telescopic pipe 50 is connected to the first pipeline joint 111. The telescopic pipe 50 is preferably a corrugated pipe, and the corrugated pipe can be connected to the water inlet or drainage pipeline. Alternatively, the corrugated pipe is used as a protective pipe and is sleeved outside part of the pipeline to protect the pipeline. At this time, it is not part of the water circuit and does not need to be connected to the first pipeline joint 111 on the first fixing seat 11.

[0096] In other embodiments, as Figure 7 shown, the first part 41 of the first telescopic structure 40 includes a plurality of first sliding rods 411 connected to the first mounting seat 10, and a first sliding ring 412 connected to the first sliding rods 411. Preferably, the plurality of first sliding rods 411 are evenly distributed along the same circumference. The first ends of the plurality of first sliding rods 411 are fixedly connected to the first mounting seat 10, and the second ends of the plurality of first sliding rods 411 are circumferentially distributed and connected to the first sliding ring 412.

[0097] The second part 42 of the first telescopic structure 40 includes a plurality of second sliding rods 421 connected to the second mounting seat 20, and a second sliding ring 422 connected to the second sliding rods 421. Preferably, the plurality of second sliding rods 421 are evenly distributed along the same circumference. The first ends of the plurality of second sliding rods 421 are fixedly connected to the second mounting seat 20, and the second ends of the plurality of second sliding rods 421 are circumferentially distributed and connected to the second sliding ring 422.

[0098] The first slip ring 412 is slidably sleeved on the second slide bar 421, and the second slip ring 422 is slidably sleeved on the first slide bar 411. The first slip ring 412 is located between the second slip ring 422 and the second mounting seat 20, and the second slip ring 422 is located between the first slip ring 412 and the first mounting seat 10. The first slip ring 412 and the second slip ring 422 limit each other. The space between multiple first slide bars 411 and multiple second slide bars 421 together constitutes the mounting space. The first part 41 and the second part 42 can achieve overall telescoping through relative sliding, changing the length of the first telescopic structure 40, that is, changing the length of the mounting space. Also, through the mutual limitation of the first slip ring 412 and the second slip ring 422, the first part 41 and the second part 42 cannot be separated.

[0099] As Figure 2 shown, the second telescopic structure 60 includes a telescopic rod 61 and a telescopic cylinder 62. The telescopic rod 61 is arranged on the first mounting seat. Preferably, a threaded hole is axially arranged at the end of the telescopic rod 61, and a mounting through hole is arranged on the first mounting seat. A connecting piece passes through the mounting through hole and is connected to the threaded hole. In this embodiment, as Figure 10 shown, the connecting piece is a screw and is connected to the threaded hole on the telescopic rod 61. The telescopic cylinder 62 is arranged on the second mounting seat. The telescopic rod 61 extends into the telescopic cylinder 62 and can slide relative to the telescopic cylinder 62. Specifically, one end of the telescopic rod 61 is arranged on the first mounting seat, and the other end extends into the telescopic cylinder 62. The overall length of the second telescopic structure 60 is adjusted by relative sliding.

[0100] Preferably, the telescopic cylinder 62 is constructed as a tubular structure with openings at both ends. A first limiting structure is formed by the radially inward protrusion at the first end opening of the telescopic cylinder 62. The second end of the telescopic cylinder 62 is connected to the second mounting seat. Preferably, a flange structure can be arranged at the second end of the telescopic cylinder 62 and connected to the second mounting seat through the flange structure; a second limiting structure is formed by the radially outward protrusion at the first end of the telescopic rod 61. The second end of the telescopic rod 61 extends out from the first end of the telescopic cylinder 62 structure and is connected to the first mounting seat. Preferably, the second end of the telescopic rod 61 can be connected by screws, or an external thread can be arranged at the second end of the telescopic rod 61. Correspondingly, a threaded hole is arranged on the first mounting seat, and the telescopic rod 61 is installed by means of threaded connection. The first limiting structure and the second limiting structure limit each other, enabling the telescopic rod 61 and the telescopic cylinder 62 to be slidably connected. The water inlet pipeline 70 is wound around the second telescopic structure 60 and can change its length as the second telescopic structure 60 expands and contracts.

[0101] Preferably, as Figure 10 shown, the first end of the telescopic cylinder 62 is provided with an anti-wear chamfer 621, so that the outer diameter of the second end of the telescopic cylinder 62 is reduced, thereby reducing the friction between the end part and the water inlet pipeline 70 and reducing the wear of the water inlet pipeline 70.

[0102] The present invention further provides a washing machine, as Figure 12 shown, comprising:

[0103] A frame 2, on which a plurality of treatment barrel mounting positions are provided for mounting a laundry treatment barrel;

[0104] The laundry treatment barrel includes a drawer-type treatment barrel 1, which is slidably connected to the frame 2 and can be pulled out from the frame 2 for loading or collecting clothes, or pushed into the frame 2. The drawer-type treatment barrel 1 constitutes a first component, and the frame 2 constitutes a second component. The above-mentioned telescopic pipeline arrangement structure is provided between the first component and the second component, that is, the telescopic pipeline arrangement structure is connected between the drawer-type treatment barrel 1 and the frame 2.

[0105] The first mounting seat 10 is mounted on the drawer-type treatment barrel 1, and the second mounting seat 20 is mounted on the frame 2. The drawer-type treatment barrel 1 is pulled out from the front side of the frame 2, and the second mounting seat 20 is mounted on the rear side of the frame 2. When the drawer-type treatment barrel 1 is pulled or pushed, the telescopic pipeline arrangement structure moves with it to make the whole elongate or contract.

[0106] Preferably, in this embodiment, the first mounting seat 10 is mounted on the left edge of the drawer-type treatment barrel 1, and the second mounting seat 20 is mounted on the right edge of the drawer-type treatment barrel 1. When the drawer-type treatment barrel 1 is pulled, the first rotating seat 12 and the second rotating seat 22 rotate. At the same time, the connecting rod structure 30, the first telescopic structure 40 and the second telescopic structure 60. When the drawer-type treatment barrel 1 is pushed, the first rotating seat 12 and the second rotating seat 22 reverse, and the connecting rod structure 30 and the first telescopic structure 40 shorten.

[0107] Moreover, when the drawer-type treatment barrel 1 is pushed to the innermost position of the frame 2, the connecting rod structure 30, the first telescopic structure 40 and the second telescopic structure 60 all form a small angle with the back surface of the drawer-type treatment barrel 1, which can reduce the occupied space, thereby reducing the gap between the back of the drawer-type treatment barrel 1 and the frame 2, and making the frame 2, that is, the overall size of the whole machine, smaller.

[0108] In this embodiment, the drawer-type treatment barrel 1 includes a drawer structure and an impeller washing barrel arranged inside it. The water inlet pipelines, strong and weak electric lines of the impeller washing barrel are arranged on the connecting rod structure 30, and the drain pipeline is arranged on the first telescopic structure 40, or the water inlet pipeline 70 is arranged on the second telescopic structure 60. Preferably, bellows are used at the connection points of the water inlet pipeline and the drain pipeline with the drawer-type treatment barrel 1 to prevent the connection points from being pulled or excessively worn when the pipelines move.

[0109] The present invention realizes the installation of pipelines or lines connecting between two moving components through a retractable pipeline layout structure, thereby avoiding the influence of movement on the pipelines and lines, and can also realize pipeline separation to improve safety. Moreover, this installation structure is convenient to install, has a compact structure, can be used in narrow spaces, and has a wider scope of application.
