[0053] The present invention utilizes a retractable pipeline arrangement structure to install pipelines and circuits between two relatively moving components. This allows the pipelines and circuits to move with the components while remaining well protected, minimizing the impact of movement on the pipelines and improving stability. This also allows for pipeline separation, enhancing safety. Furthermore, the installation structure is easy to install, compact, and suitable for use in confined spaces, broadening its applicability. The present invention is described in detail below with reference to specific embodiments.

[0054] like Figure 1 、 Figure 2 As shown, the present invention provides a retractable pipeline arrangement structure, which is arranged between a first component and a second component that are relatively movable, and is used to install connecting pipes and / or lines between the first component and the second component, such as water inlet pipes, drainage pipes, power supply lines, control lines, etc. The retractable pipeline arrangement structure includes:

[0055] The first mounting base 10 includes a first fixed base 11 and a first rotating base 12, and the first rotating base 12 is connected to the first fixed base 11;

[0056] The second mounting base 20 includes a second fixed base 21 and a second rotating base 22, and the second rotating base 22 is connected to the second fixed base 21;

[0057] The circuit installation structure includes a connecting rod structure 30, with both ends of the connecting rod structure 30 connected to the first rotating seat 12 and the second rotating seat 22 respectively;

[0058] Pipeline installation structure, including:

[0059] The second telescopic structure 40 is telescopically arranged between the first rotating seat 12 and the second rotating seat 22, and an installation space for installing a drain pipe is formed therein.

[0060] The first telescopic structure 60 is telescopically arranged between the first rotating seat 12 and the second rotating seat 22, and its outer peripheral wall is used to support the water inlet pipe.

[0061] A plurality of mounting positions for mounting the first telescopic structure 60 are correspondingly provided on the first rotating base 12 and the second rotating base 22 .

[0062] like Figure 1 As shown, in this embodiment, the first mounting base 10 includes:

[0063] The first fixing seat 11 is used for fixed connection with the first component. The first fixing seat 11 is provided with a fixed connection portion. Preferably, the fixed connection portion is constructed as a plate-like structure including multiple through holes, and can be fixedly connected to the first component via a connecting member such as bolts. The fixed connection portion is provided with a rotating connection portion for hinged connection with the first rotating seat 12.

[0064] Preferably, if Figure 11 As shown, the first fixing seat 11 is provided with a first pipe connector 111 for connecting to the pipeline. The first pipe connector 111 can be provided on the fixed connection portion, or a support plate can be provided on the fixed connection portion, and the first pipe connector 111 is provided on the support plate. The connection of the pipeline is achieved through the first pipe connector 111, so that the first pipe connector 111 can move synchronously with the movement of the entire installation structure, avoiding loosening of the joint during movement and affecting the sealing. Furthermore, one or more first pipe connectors 111 can be provided, and the diameters of the multiple first pipe connectors 111 can be different to enable the installation of a variety of different pipelines.

[0065] The first mounting base 10 also includes a first rotating base 12, which is hingedly connected to the first fixed base 11. The first rotating base 12 includes a main body, which is constructed as a narrow, long plate-like structure. On one side of the main body is a first rotating base 121 that cooperates with the rotating connection portion on the first fixed base 11. Preferably, a rib is provided between the first rotating base 121 and the main body to increase the strength of the main body. The first rotating base 121 and the rotating connection portion are rotatably connected via a rotating shaft, allowing the first rotating base 12 to rotate relative to the first fixed base 11. Preferably, in this embodiment, two first fixed bases 11 are provided, and the two first fixed bases 11 are arranged at a certain distance and arranged vertically up and down. Correspondingly, two first rotating bases 121 are provided on the first rotating base 12, and the two first fixed bases 11 and the two first rotating bases 121 correspond one-to-one to form two pairs of rotating cooperation. Furthermore, the two pairs of rotating cooperation are connected by a connecting shaft to facilitate assembly.

[0066] like Figure 6 、 Figure 7 As shown, the first rotating seat 12 also includes: a first hinge portion 122 connected to the connecting rod structure 30, the first hinge portion 122 is hinged to one end of the connecting rod structure 30, and the first hinge portion 122 is at the upper end of the main body, preferably including two support portions, the two support portions are arranged opposite each other and spaced a certain distance apart, and the ends of the two support portions are each provided with a hinge hole, the axes of the two hinge holes are collinear, the end of the connecting rod structure 30 extends between the two support portions, and is passed through the two hinge holes and the connecting rod structure 30 by a pin or other structure to achieve hinge connection. It is easy to imagine that only one support portion can be provided to achieve hinge connection with the connecting rod structure 30.

[0067] The first rotating seat 12 also includes: a first fixing portion 123 connected to the first part 41, the first fixing portion 123 is arranged at the lower end of the main body, and a through hole connected to the installation space is provided on the first fixing portion 123, and a water pipe or line can pass through the through hole into the installation space.

[0068] like Figure 8 、 Figure 9 As shown, a first telescopic structure connecting hole 124 is provided on the first rotating seat 12. Preferably, a plurality of first telescopic structure connecting holes 124 can be provided along its extending direction, so that multiple first telescopic structures 60 can be installed or the installation position can be adjusted.

[0069] The second mounting base 20 includes:

[0070] A second fixing seat 21, used for fixed connection with the second component;

[0071] The second rotating seat 22 is hinged to the second fixed seat 21.

[0072] The second rotating base 22 has the same structure as the first rotating base 12 and includes a main body with a second hinged portion 222 connected to the connecting rod structure 30, hingedly connected to one end of the connecting rod structure 30; and / or a second fixed portion 223 connected to the second portion 42, with a through hole provided in the second fixed portion 223 that communicates with the installation space. The main body also includes a second rotating base 221, which is rotatably connected to the second fixed base 21.

[0073] In this embodiment, the structure of the second fixed seat 21 is the same as that of the first fixed seat 11. A second pipe connector 211 is provided on the second fixed seat 21 for connecting to the pipeline. Alternatively, part of the structure of the second fixed seat 21 may be partially different from that of the first fixed seat 11 depending on 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 is not described in detail here.

[0074] Specifically, if Figure 2 、 Figure 3 As shown, the connecting rod structure 30 includes:

[0075] A first connecting rod 31, a first end of the first connecting rod 31 is hinged to the first mounting seat 10;

[0076] a second connecting rod 32 , wherein a first end of the second connecting rod 32 is hinged to a second end of the first connecting rod 31 ;

[0077] The third connecting rod 33 has a first end hinged to the second end of the second connecting rod 32, and a second end hinged to the second mounting base 20. Preferably, the first connecting rod 31, the second connecting rod 32, and the third connecting rod 33 are connected by a rotating shaft. The first connecting rod 31, the second connecting rod 32, and the third connecting rod 33 are each provided with a hinge hole at both ends. The hinge connection between the two connecting rods is achieved by inserting a rotating shaft, a connecting pin, or other structures into 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. The first connecting rod 31 and the third connecting rod 33 form an angle with the second connecting rod 32, and the angle can change with the relative movement of the first mounting base 10 and the second mounting base 20, thereby achieving the extension and contraction 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 as needed.

[0078] Alternatively, the connecting rod structure 30 may be replaced by a structure similar to the connecting rod structure 30. For example, the connecting rod structure 30 may be replaced by a drag chain structure, and a connecting cavity for setting up pipelines or lines is formed inside the drag chain structure.

[0079] 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, and the fixing structure is used to fix the pipeline and / or line. It is preferred to provide a fixing structure on the three connecting rods at the same time to make the fixation of the pipeline and / or line more reliable and enable the pipeline and / or line to be arranged along the connecting rod structure 30.

[0080] Preferably, the fixing structure includes a first clamping structure for fixing the line, and / or a second clamping structure for fixing the pipeline. In this embodiment, the first clamping structure and the second clamping structure are provided at the same time.

[0081] Furthermore, the first connecting rod 31, the second connecting rod 32 and the third connecting rod 33 are constructed as a plate-like structure. The connecting rod structure 30 formed by the three is connected and includes a first mounting surface and a second mounting surface. A first clamping structure is formed on the first mounting surface for fixing circuits, such as power supply and control circuits, 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 the two surfaces of the connecting rod structure 30 to separate the waterway and the circuit to avoid mutual influence between water and electricity.

[0082] like Figure 3 As shown, the first clamping structure preferably includes a strong current clamping structure 301 for fixing the power supply line, and a weak current clamping structure 302 for fixing the control line, so as to achieve the separation of strong current and weak current, make the line layout more tidy, and avoid mutual interference between strong current and weak current.

[0083] The second connecting structure includes a water pipe slot for connecting the water pipe. Preferably, the water pipe slots are provided on the first connecting rod 31, the second connecting rod 32, and the third connecting rod 33, so that the water pipe can be arranged along the connecting rod structure 30. In this embodiment, an anti-freeze crack structure 34 is provided on the waterway. The anti-freeze crack structure 34 is connected to the waterway as part of the waterway. Preferably, the second connecting rod 32 is located at the low point of the connecting rod structure 30. The anti-freeze crack structure 34 is provided on the second connecting rod. The water pipe is divided into two parts, which are respectively connected to the first connecting rod 31 and the second connecting rod 32, and then connected to the anti-freeze crack structure 34 at the same time.

[0084] When the anti-freeze crack structure 34 is provided, a water pipe slot is not required on the second connecting rod 32. Furthermore, to facilitate the installation of the anti-freeze crack structure 34, a first water pipe slot is provided on the first connecting rod 31 near its first end, and a second water pipe slot 303 is provided near its second end (near the second connecting rod 32). The anti-freeze crack structure 34 is located on the lower side of the second connecting rod 32, and the second water pipe slot 303 protrudes toward the lower side of the first connecting rod 31 to facilitate the connection of the pipeline through the second water pipe slot 303 and the anti-freeze crack structure 34. In this embodiment, the third connecting rod 33 and the first connecting rod 31 form a symmetrical structure and are symmetrically provided at both ends of the second connecting rod 32.

[0085] like Figure 4 、 Figure 5 As shown, preferably, the anti-freeze cracking structure 34 includes a water flow channel 341, which is connected to the waterway for water circulation. Preferably, the water flow channel 341 is a tubular structure arranged along the extension direction of the second connecting rod 32, and its two ends are respectively used to communicate with the pipeline.

[0086] The antifreeze structure also includes an air cavity 342, which is located on the upper side of the water flow channel 341 and is connected to the water flow channel 341 through a connecting hole 343. Preferably, the aperture of the connecting hole 343 is small. When water flows in the water flow channel 341, the water flow will block the connecting hole 343, and due to the presence of air in the exhaust cavity 342, water will not enter the air cavity 342, or only a small amount of water will enter the air cavity 342. When there is little water in the water flow channel 341, since the air cavity 342 is located on the upper side of the water flow channel 341, the water in the air cavity 342 will flow out under the action of gravity; when the ambient temperature drops, the air in the air cavity 342 shrinks, and the water in the water flow channel 341 expands when it freezes, and a part of it enters the air cavity 342 through the connecting hole 343, thereby preventing the expansion of the water freezing volume from causing the pipeline to rupture. Since the anti-freeze crack 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-freeze crack structure 34, preventing ice from affecting the entire pipeline.

[0087] In this embodiment, if Figure 6As shown, the second telescopic structure 40 is constructed as a sleeve assembly, that is, the first part 41 and the second part 42 are both constructed as cylindrical structures, which are put together and can slide relative to each other. Among them, the first part 41 and the second part 42 can be formed integrally 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 and the first rotating seat 12 are formed separately and detachably connected. For example, an internal thread can be provided in the through hole of the first fixing portion 123, and an external thread can be provided at the first end of the first part 41. The first part 41 is connected by threads, or a flange structure can be provided at the first end of the first part 41, and connected by a flange matching connector. The second part 42 and the second rotating seat 22 are formed integrally.

[0088] Furthermore, the radial dimension of the first part 41 is smaller than the radial dimension of the second part 42, and the first part 41 extends into the second part 42. A guide structure is axially arranged on the first part 41 and the second part 42. For example, a partial annular protrusion is arranged on the outer peripheral wall of the second end of the first part 41 to form a limiting guide protrusion 410. Correspondingly, a partial annular groove matching the shape of the limiting guide protrusion 410 is arranged on the inner peripheral wall of the second part 42, and extends axially to form a limiting guide groove, and the limiting guide groove is closed at the end of the second part, so that the limiting guide protrusion 410 and the limiting guide groove cooperate to limit and guide the sliding of the first part 41 and the second part 42 in the axial direction, and limit the first part 41 and the second part 42 in the circumferential direction so that the two cannot rotate relative to each other.

[0089] Alternatively, a groove is formed on the outer peripheral wall of the first part 41 along its axial direction, and a protrusion is provided on the corresponding inner peripheral wall of the second part 42 along its axial direction. The protrusions extend into the groove and can slide against 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.

[0090] Alternatively, two or more second telescopic structures 40 may be provided simultaneously to facilitate the installation of different pipelines or lines. For example, two second telescopic structures 40 may be provided, and the two second telescopic structures 40 may adopt different structures or the same structure. Of course, more second telescopic structures 40 may be provided as needed.

[0091] Preferably, if Figure 1 、 Figure 2As shown, the apparatus further includes a telescopic tube 50, which is disposed within the installation space. The two ends of the telescopic tube 50 are connected to the first pipe connector 111 and the second pipe connector 211, respectively. The telescopic tube 50 is preferably a corrugated tube that can be connected to the water inlet or drain pipe. Alternatively, the corrugated tube can serve as a protective tube, fitted over the outside of a portion of the pipe to protect it. In this case, the bellows does not form part of the waterway and need not be connected to the first pipe connector 111 on the first fixing base 11 or the second pipe connector 211 on the second fixing base 21.

[0092] In other embodiments, Figure 7 As shown, the first part 41 of the second 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 distributed along the circumference and connected to the first sliding ring 412.

[0093] The second part 42 of the second 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 distributed along the circumference and connected to the second sliding ring 422.

[0094] The first sliding ring 412 slides onto the second sliding rod 421, and the second sliding ring 422 slides onto the first sliding rod 411. The first sliding ring 412 is positioned between the second sliding ring 422 and the second mounting base 20, and the second sliding ring 422 is positioned between the first sliding ring 412 and the first mounting base 10. The first sliding ring 412 and the second sliding ring 422 mutually restrict each other, and the spaces between the multiple first sliding rods 411 and the multiple second sliding rods 421 collectively constitute the installation space. The first portion 41 and the second portion 42 can achieve overall telescopic expansion and contraction by sliding relative to each other, thereby changing the length of the second telescopic structure 40, and thus the length of the installation space. Furthermore, the mutual restriction of the first sliding ring 412 and the second sliding ring 422 prevents the first portion 41 and the second portion 42 from separating.

[0095] like Figure 2 As shown, the first telescopic structure 60 includes a telescopic rod 61 and a telescopic cylinder 62. The telescopic rod 61 is mounted on a first mounting seat, and the telescopic cylinder 62 is mounted on a 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 mounted on the first mounting seat, and the other end extends into the telescopic cylinder 62. The overall length of the first telescopic structure 60 can be adjusted by relative sliding.

[0096] Preferably, the telescopic cylinder 62 is constructed as a cylindrical structure with two ends open. The first end of the telescopic cylinder 62 protrudes radially inward at the opening to form a first limiting structure. The second end of the telescopic cylinder 62 is connected to the second mounting seat. Preferably, a flange structure can be provided at the second end of the telescopic cylinder 62 to connect to the second mounting seat via the flange structure. The first end of the telescopic rod 61 protrudes radially outward to form a second limiting structure. The second end of the telescopic rod 61 extends from the first end of the telescopic cylinder 62 and is connected to the first mounting seat. Preferably, the second end of the telescopic rod 61 can be connected by screws, or the second end of the telescopic rod 61 can be provided with external threads. Correspondingly, a threaded hole is provided on the first mounting seat to install the telescopic rod 61 via a threaded connection. The first and second limiting structures limit the position of the telescopic rod 61 and the telescopic cylinder 62, allowing the telescopic rod 61 to be slidably connected. The water inlet pipe 70 is wrapped around the first telescopic structure 60 and can change length as the first telescopic structure 60 is extended or retracted.

[0097] Preferably, if Figure 10 As shown, the first end of the telescopic cylinder 62 is provided with an anti-wear chamfer 621 to reduce the outer diameter of the second end of the telescopic cylinder 62, thereby reducing the friction between the end and the water inlet pipe 70 and reducing the wear of the water inlet pipe 70.

[0098] The present invention also provides a washing machine, such as Figure 12 Shown, including:

[0099] Frame 2, frame 2 is provided with a plurality of processing barrel installation positions for installing clothing processing barrels;

[0100] The laundry tub includes a drawer-type tub 1, which is slidably connected to a frame 2 and can be withdrawn from the frame 2 for loading or unloading laundry, or pushed back into the frame 2. The drawer-type tub 1 constitutes a first component, and the frame 2 constitutes a second component. The retractable pipeline arrangement structure is disposed between the first and second components, that is, the retractable pipeline arrangement structure is connected between the drawer-type tub 1 and the frame 2.

[0101] The first mounting seat 10 is installed on the drawer-type processing barrel 1, and the second mounting seat 20 is installed on the frame 2. The drawer-type processing barrel 1 is pulled out from the front side of the frame 2, and the second mounting seat 20 is installed on the rear side of the frame 2. When the drawer-type processing barrel 1 is pulled out or pushed, the retractable pipeline arrangement structure follows its movement to extend or contract it as a whole.

[0102] Preferably, in this embodiment, the first mounting seat 10 is installed on the left edge of the drawer-type processing bucket 1, and the second mounting seat 20 is installed on the right edge of the drawer-type processing bucket 1. When the drawer-type processing bucket 1 is pulled, the first rotating seat 12 and the second rotating seat 22 rotate, and at the same time, the connecting rod structure 30, the second telescopic structure 40 and the first telescopic structure 60 push the drawer-type processing bucket 1, the first rotating seat 12 and the second rotating seat 22 reverse, and the connecting rod structure 30 and the second telescopic structure 40 shorten.

[0103] Moreover, when the drawer-type processing bucket 1 is pushed to the innermost position of the frame 2, the connecting rod structure 30, the second telescopic structure 40 and the first telescopic structure 60 all form a smaller angle with the back of the drawer-type processing bucket 1, which can reduce the space they occupy, thereby reducing the gap between the back of the drawer-type processing bucket 1 and the frame 2, making the frame 2 and the entire machine smaller.

[0104] In this embodiment, the drawer-type treatment tub 1 includes a drawer structure and a pulsator washing tub disposed therein. The high-voltage and low-voltage lines of the pulsator washing tub's water inlet pipeline are disposed on the connecting rod structure 30, and the drainage pipeline is disposed on the second telescopic structure 40. Alternatively, the water inlet pipeline 70 is disposed on the first telescopic structure 60. Preferably, the connections between the water inlet and drainage pipelines and the drawer-type treatment tub 1 are both made of bellows to prevent the connections from being pulled or excessively worn during pipe movement.

[0105] The present invention realizes the installation of the pipeline or line connecting two moving parts through a retractable pipeline arrangement structure, thereby avoiding the impact of movement on the pipeline and line, and can also realize pipeline separation to improve safety. In addition, the installation structure is easy to install, has a compact structure, can be used in narrow spaces, and has a wider range of applications.
