[0064] It should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a commodity or system comprising a series of elements not only includes those elements but also includes other elements not explicitly listed, or elements inherent to such commodity or system. Without further limitation, an element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the commodity or system comprising the said element.

[0065] In the present invention, the pipeline and circuit between two relatively movable components are installed through a pipeline installation 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, has a compact structure, can be used in narrow spaces, and has a wider application range. The following provides a detailed introduction to the present invention in combination with specific embodiments.

[0066] As Figure 1 、 Figure 2 shown, the present invention provides a pipeline installation structure, which is arranged between a first component and a second component that can move relatively, and is used for installing 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 pipeline installation structure includes:

[0067] A first mounting seat 10, hinged to the first component;

[0068] A second mounting seat 20, hinged to the second component;

[0069] The first mounting seat 10 and the second mounting seat 20 are connected through a connecting structure,

[0070] The connecting structure includes:

[0071] A connecting rod structure 30, hinged to the first mounting seat 10 and the second mounting seat 20 respectively, for fixing the pipeline and / or circuit; and / or,

[0072] A telescopic cage structure 40, including a first part 41 connected to the first mounting seat 10 and a second part 42 connected to the second mounting seat 20, the first part 41 and the second part 42 are slidably connected, and an installation space for the pipeline and / or circuit is formed on the telescopic cage structure 40.

[0073] Specifically, as Figure 3 , Figure 4 shown, the connecting rod structure 30 includes:

[0074] The first connecting rod 31, the first end of the first connecting rod 31 is hinged to the first mounting seat 10;

[0075] The 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;

[0076] The 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 may also be provided with more connecting rods, such as four connecting rods, five connecting rods, etc., which can be set as needed.

[0077] 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.

[0078] 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 the three connecting rods at the same time to make the fixing of pipelines and / or lines more reliable, and can make the pipelines and / or lines can be arranged along the connecting rod structure 30.

[0079] 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.

[0080] Further, 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 drain 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.

[0081] 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, make the line layout more tidy, and also avoid mutual interference between strong electricity and weak electricity.

[0082] 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.

[0083] Such as Figure 4 As shown, when the anti-freezing and cracking structure 34 is provided, a water pipe slot does not need to be provided on the second link 32. Further, in order to cooperate with the installation of the anti-freezing and cracking structure 34, a first water pipe slot 304 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 60 to pass through the second water pipe slot 303 and connect with 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.

[0084] Such as Figure 5 、 Figure 6 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 60.

[0085] The anti-freezing structure further includes an air cavity 342. The air cavity 342 is located above the water flow channel 341 and is communicated with 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 in volume. And because the anti-freezing 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-freezing crack structure 34, avoiding the impact of freezing on the entire pipeline.

[0086] In this embodiment, as Figure 7 shown, the first part 41 of the telescopic cage 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.

[0087] The second part 42 of the telescopic cage 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.

[0088] The first sliding ring 412 is slidably sleeved on the second sliding rod 421, and the second sliding ring 422 is slidably sleeved on the first sliding rod 411. The first sliding ring 412 is located between the second sliding ring 422 and the second mounting seat 20, and the second sliding ring 422 is located between the first sliding ring 412 and the first mounting seat 10. The first sliding ring 412 and the second sliding ring 422 limit each other. The space between the plurality of first sliding rods 411 and the plurality of second sliding rods 421 together forms an installation space. The first part 41 and the second part 42 can achieve overall telescoping through relative sliding, changing the length of the telescopic cage structure 40, that is, changing the length of the installation space. Also, through the mutual limitation of the first sliding ring 412 and the second sliding ring 422, the first part 41 and the second part 42 cannot be separated.

[0089] Preferably, in other embodiments, the telescopic cage structure 40 can also be configured as a sleeve assembly, that is, both the first part 41 and the second part 42 are configured as cylindrical structures, which are sleeved together and can slide 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. Further, guiding structures are axially provided on the first part 41 and the second part 42. For example, 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, a groove is formed along the axial direction on the outer peripheral wall of the first part 41, and correspondingly, a protrusion is axially provided on the inner peripheral wall of the second part 42, and 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 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 telescopic cage structures 40 can also be provided simultaneously to cooperate with the installation of different pipelines or lines. For example, two telescopic cage structures 40 can be provided, and the two telescopic cage structures 40 can adopt different structures or the same structure. For example, a telescopic tube or a telescopic rod structure can be provided. Of course, more telescopic cage structures 40 can also be provided according to needs.

[0091] As Figure 1 shown, in this embodiment, the first mounting seat 10 includes:

[0092] A first fixing seat 11 for fixedly connecting with the first component. A fixed connecting portion is provided on the first fixing seat 11. Preferably, the fixed connecting portion 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 members such as bolts. A rotating connecting portion is provided on the fixed connecting portion for hingedly connecting with the first rotating seat 12.

[0093] Preferably, as Figure 9 、 Figure 7 shown, a first pipeline joint 111 is provided on the first fixing seat 11 for communicating with the pipeline. The first pipeline joint 111 can be provided on the fixed connecting portion, or a support plate is provided on the fixed connecting portion, and the first pipeline joint 111 is provided 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 provided, and the diameters of the multiple first pipeline joints 111 can be different to realize the installation of multiple different pipelines.

[0094] The first mounting seat 10 further includes a first rotating seat 12. The first rotating seat 12 is hinged to the first fixed seat 11. The first rotating seat 12 includes a main body portion, which is configured as a narrow and long plate-like structure. On one side thereof, there is provided a first rotating base 121 that cooperates with the rotating connection portion on the first fixed seat 11. Preferably, a rib plate is provided between the first rotating base 121 and the main body portion to increase the strength of the main body portion. The first rotating base 121 and the rotating connection portion are rotationally connected by a rotating shaft, so that the first rotating seat 12 can rotate relative to the first fixed seat 11. Preferably, in this embodiment, there are two first fixed seats 11, and the two first fixed seats 11 are arranged at a certain distance apart and are arranged vertically up and down; correspondingly, there are two first rotating bases 121 on the first rotating seat 12, and the two first fixed seats 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 to facilitate assembly and improve the overall strength and stability. Similarly, there are also two second fixed seats 21, and two pairs of rotational fits are formed between the two second fixed seats 21 and the second rotating seat 22 and are connected by a second connecting shaft 23.

[0095] As Figure 7 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 at a certain distance apart. 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.

[0096] 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.

[0097] Preferably, when multiple telescopic cage structures 40 are provided, other installation portions can also be provided at a position on the main body portion between the first hinged portion 122 and the first fixing portion 123 for installing more telescopic cage structures 40 or other structures.

[0098] The second mounting seat 20 includes:

[0099] A second fixed seat 21 for fixedly connecting to a second component;

[0100] The second rotating seat 22, the second rotating seat 22 is hinged to the second fixed seat 21,

[0101] The second rotating seat 22 has the same structure as the first rotating seat 12, including: a main body portion, on which a second hinge portion 222 connected to the link structure 30 is provided, and the second hinge 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 with the second fixed seat 21.

[0102] 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 with 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.

[0103] Preferably, as Figure 1 、 Figure 2 shown, a telescopic tube 50 is further included. The telescopic tube 50 is arranged in the installation space, and both ends of the telescopic tube 50 are respectively connected to the first pipeline joint 111 and the second pipeline joint 211. The telescopic tube 50 is preferably a corrugated tube, and the corrugated tube can be connected to the water inlet or drain pipeline. Or, the corrugated tube is used as a protection tube and is sleeved outside part of the pipeline to protect the pipeline. At this time, it is not part of the water circuit and can be not connected to the first pipeline joint 111 on the first fixed seat 11 and the second pipeline joint 211 on the second fixed seat 21.

[0106] 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 putting in or taking out clothes, or pushed into the frame 2. The drawer-type treatment barrel 1 constitutes the first component, and the frame 2 constitutes the second component. The above pipeline installation structure is arranged between the first component and the second component, that is, the pipeline installation structure is connected between the drawer-type treatment barrel 1 and the frame 2.

[0107] 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 drawn 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 pipeline installation structure moves with it to make the whole elongate or contract.

[0108] Preferably, the first mounting seat 10 is mounted on the first side edge of the frame 2, and the second mounting seat 20 is mounted on the second side edge on the back of the drawer-type treatment barrel 1. The first side edge and the second side edge are arranged diagonally opposite, so that the pipeline installation structure is obliquely arranged between the frame and the drawer-type treatment barrel, that is, the pipeline installation structure is obliquely arranged along the diagonal in the space between the drawer-type treatment barrel 1 and the frame 2.

[0109] Specifically, 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, and at the same time, the connecting rod structure 30 and the telescopic cage structure 40 elongate. 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 telescopic cage structure 40 shorten.

[0110] Moreover, when the drawer-type treatment barrel 1 is pushed to the innermost position of the frame 2, both the connecting rod structure 30 and the telescopic cage structure 40 form a smaller 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, so that the size of the frame 2, that is, the whole machine, can be smaller.

[0111] In this embodiment, the laundry treatment device is a washing machine. The drawer-type treatment barrel 1 includes a drawer structure and a pulsator washing barrel arranged inside it. The water inlet pipeline, the strong electricity and weak electricity lines of the pulsator washing barrel are arranged on the connecting rod structure 30, and the drainage pipeline is arranged on the telescopic cage structure 40. Preferably, bellows are used at the joints of the water inlet pipeline and the drainage pipeline with the drawer-type treatment barrel 1 to prevent the joints from being pulled or excessively worn when the pipeline moves.

[0112] Furthermore, a reducing connector 70 is also arranged on the water inlet pipe, as Figure 11 shown. The reducing connector 70 includes an outlet end 72 with a larger pipe diameter and an inlet end 71 with a smaller pipe diameter. The inlet end 71 is connected to the water inlet pipeline, and the outlet end 72 is communicated with the inlet of the pulsator washing barrel. When the incoming water flow passes from the inlet end 71 to the outlet end 72, the water inlet pressure can be reduced to avoid the incoming water shock wave wheel flip cover, resulting in a large incoming water abnormal noise. Preferably, an installation part 73 is also arranged on the reducing connector 70 for the fixed installation of the reducing connector 70.

[0113] The present invention realizes the installation of pipelines or lines connecting between two moving components through a pipeline installation 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 application range.

[0114] The exemplary embodiments of the present disclosure have been specifically shown and described above. It should be understood that the present disclosure is not limited to the detailed structures, settings or implementation methods described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent settings included within the spirit and scope of the appended claims.
