[0067] It should also be noted that the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that a commodity or system including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such commodity or system. Without further limitation, the element defined by the statement "including one..." does not exclude the existence of additional identical elements in the commodity or system including the said element.

[0068] The present invention installs pipelines and lines between two relatively moving components through a pipeline installation structure, enabling the pipelines and lines to be well protected while moving with the components, reducing the impact of movement on the pipelines, improving stability, and also being able to achieve 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. The following provides a detailed introduction to the present invention in combination with specific embodiments.

[0069] As Figures 1 - 4 shown, the present invention provides a pipeline installation structure disposed between a first component and a second component that can move relative to each other, for installing the connecting pipeline and / or line 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. This pipeline installation structure includes: a first mounting seat 10 connected to the first component; a second mounting seat 20 connected to the second component; and a connecting structure connected between the first mounting seat and the second mounting seat. Among them, the connecting structure can be bent and / or telescoped along with the relative movement between the first component and the second component.

[0070] Further, the connecting structure includes:

[0071] a connecting rod structure 30, the two ends of which are respectively hinged to the first mounting seat 10 and the second mounting seat 20, for fixing the pipeline and / or line; and / or,

[0072] The telescopic structure 40 includes 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 or installation cavity for the arrangement of pipelines and / or lines is formed on the telescopic structure 40.

[0073]

Linkage Structure

[0074] Specifically, as Figure 5 , Figure 6 shown, the linkage structure 30 includes:

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

[0076] A second link 32, the first end of the second link 32 is hinged to the second end of the first link 31;

[0077] A third link 33, the first end of the third link 33 is hinged to the second end of the second link 32, and the second end of the third link 33 is hinged to the second mounting seat 20.

[0078] Preferably, the first link 31, the second link 32 and the third link 33 are connected by a rotating shaft. Hinge holes are provided at both ends of the first link 31, the second link 32 and the third link 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 link 31 and the third link 33 are hinged at both ends of the second link 32. An included angle is formed between the first link 31 and the third link 33 and the second link 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 linkage structure 30. Preferably, in other embodiments, the linkage structure 30 can also be provided with more links, such as four links, five links, etc., which can be set according to needs.

[0079] Alternatively, a structure similar to the linkage structure 30 can also be used to replace it. For example, a drag chain structure can be used to replace the linkage structure 30, and a communication cavity for the arrangement of pipelines and / or lines is formed inside the drag chain structure. Each single link of the drag chain is hinged in turn and can be bent and deformed with the movement of the first mounting seat and the second mounting seat. The pipelines and / or lines in the corresponding communication cavity also undergo corresponding deformations accordingly.

[0080] In this embodiment, a fixing structure is provided on the first link 31 and / or the second link 32 and / or the third link 33. The fixing structure is used to fix the pipelines and / or lines. Preferably, the fixing structure is provided on the three links at the same time to make the fixing of the pipelines and / or lines more reliable, and the pipelines and / or lines can be arranged along the linkage structure 30.

[0081] Preferably, the fixing structure includes a first clamping structure for fixing the circuit and / or a second clamping structure for fixing the pipeline. In this embodiment, the first clamping structure and the second clamping structure are provided simultaneously.

[0082] Furthermore, the first connecting rod 31, the second connecting rod 32, and the third connecting rod 33 are configured as plate-like structures. The connecting rod 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 circuits such as power supply and control circuits; a second clamping structure is formed on the second mounting surface for fixing pipelines such as water inlet and drainage pipelines. The first clamping structure and the second clamping structure are respectively formed on two surfaces of the connecting rod structure 30 to separate the water circuit and the electric circuit and avoid mutual influence between water and electricity.

[0083] As Figure 5 shown, the first clamping structure preferably includes a strong electricity clamping structure 301 for fixing the power supply circuit and a weak electricity clamping structure 302 for fixing the control circuit to achieve the separation of strong electricity and weak electricity, make the circuit layout neater, and also avoid mutual interference between strong electricity and weak electricity.

[0084] The second clamping structure includes a water pipe slot for clamping the water pipe. Preferably, water pipe slots are provided on the first connecting rod 31, the second connecting rod 32, and the third connecting rod 33 simultaneously, so that the water pipe can be arranged along the connecting rod 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 connecting rod 32 is located at the lowest point of the connecting rod 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 connecting rod 31 and the second connecting rod 32, and then connected to the anti-freezing and cracking structure 34 at the same time.

[0085] As Figure 6 shown, when the anti-freezing and cracking structure 34 is provided, a water pipe slot does not need to be provided on the second connecting rod 32. Furthermore, 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 connecting rod 31, and a second water pipe slot 303 is provided at a position close to its second end (close to the second connecting rod 32). The anti-freezing and cracking structure 34 is located on the lower side of the second connecting rod 32, and the second water pipe slot 303 protrudes downward from the first connecting rod 31 to facilitate the pipeline 60 to pass through the second water pipe slot 303 and connect to the anti-freezing and cracking structure 34. In this embodiment, the third connecting rod 33 and the first connecting rod 31 form a symmetric structure and are symmetrically arranged at both ends of the second connecting rod 32.

[0086]

Anti-freezing and cracking

[0087] As Figure 7 、 Figure 8As shown, preferably, the anti-freezing and cracking structure 34 includes a water flow channel 341, which is communicated with the water path to supply water to flow. Preferably, the water flow channel 341 is a tubular structure arranged along the extending direction of the second connecting rod 32, and both ends thereof are respectively used for communicating with the pipeline 60.

[0088] The anti-freezing and cracking 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, the water will not enter the exhaust cavity 342; when the ambient temperature decreases, 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, thereby preventing the pipeline from bursting due to the expansion of the frozen water in volume. And since the anti-freezing and cracking 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 and cracking structure 34, avoiding the impact of freezing on the entire pipeline.

[0089] Or, as Figure 9 shown, based on the anti-freezing and cracking structure provided on the rod body of the connecting rod structure for connecting to the pipeline, at this time, the anti-freezing and cracking structure includes an anti-freezing and cracking structure body, and a water flow channel 341 penetrating through the anti-freezing and cracking structure body and an air cavity 342 communicated above the water flow channel are formed inside. The anti-freezing and cracking structure is also arranged on the second connecting rod 32, and the second connecting rod 32 is horizontally arranged. Preferably, the water flow channel 341 is arranged horizontally in the anti-freezing and cracking structure, one end thereof serves as the water inlet, and the other end serves as the water outlet; wherein the air cavity 342 is formed in the anti-freezing and cracking structure body along the direction of the water flow channel 341, and the highest point of the air cavity 342 is higher than the water inlet or the water outlet.

[0090]

Expansion and contraction structure

[0091] As Figure 10 、 Figure 11 shown, in the embodiment, the expansion and contraction structure 40 can be constructed as an expansion and contraction sleeve, that is, both the first part 41 and the second part 42 are constructed as tubular structures, sleeved together and capable of sliding relative to each other. At this time, the expansion and contraction sleeve includes a first cylinder (i.e., the first part) connected to the first mounting seat 10 and a second cylinder (i.e., the second part) connected to the second mounting seat 20. The first cylinder and the second cylinder are sleeved together and can slide relative to each other, and an installation cavity for arranging pipelines and / or lines is formed inside the expansion and contraction sleeve.

[0092] Optionally, 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 protrusion 413 is formed on the outer peripheral wall of the first part 41 along its axis, and correspondingly, a groove 423 is axially provided on the inner peripheral wall of the second part 42. The protrusion 413 extends into the groove 423 and can slide relative to each other to guide the sliding of the first part 41 and the second part 42. Preferably, two grooves 423 and two protrusions 413 are provided; it is easy to think that a groove can also be provided on the outer peripheral wall of the first part 41, and a protrusion can be provided on the inner peripheral wall of the second part 42.

[0093] Alternatively, two or more telescopic structures 40 can be provided simultaneously to cooperate with the installation of different pipelines or lines. For example, two telescopic structures 40 can be provided, and the two telescopic structures 40 can adopt different structures or the same structure. Of course, more telescopic structures 40 can also be provided according to needs.

[0094] In addition, for the pipelines installed in the telescopic structure, such as the water inlet pipe 81 and the drain pipe 82, etc., they can all be adjusted according to the actual installation height and the number of installations. Optionally, a telescopic outer peripheral wall for winding the pipeline is formed on the outer side of the telescopic sleeve. The water inlet pipe 81 can be wound on the outer wall of the telescopic structure composed of the first cylinder and the second cylinder, as Figure 15 shown.

[0095] It should be noted that in this embodiment, the pipelines installed in the telescopic structure section can adopt pipelines with a certain telescopic deformation amount such as corrugated pipes, and can perform telescopic deformation along with the telescopic structure. When the pipeline is installed on the telescopic structure, during telescopic deformation, friction may occur between the pipeline and the telescopic structure, resulting in wear and water leakage. At this time, an anti-wear rib can be provided on the pipeline, and the telescopic sleeve can use self-lubricating materials (such as POM), etc.

[0096] In other embodiments, as Figure 12 、 Figure 13 shown, the telescopic structure 40 can be configured as a telescopic cage structure. Correspondingly, the first part 41 of the 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 telescopic structure 40 includes a plurality of second sliding rods 421 connected to the second mounting seat 20, and second sliding rings 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 rings 422.

[0098] 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 constitutes the mounting space. The first part 41 and the second part 42 can be telescopically extended and retracted by relative sliding to change the length of the telescopic structure 40, that is, to change the length of the mounting space. Also, due to 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.

[0099] In other embodiments, the telescopic structure 40 can be configured as a telescopic slide frame (not shown in the figure). Correspondingly, the first part is the first sliding member, and the second part is the second sliding member. The two sliding members cooperate to achieve telescoping. Clasps are provided at appropriate positions on the outer sides of the first sliding member and the second sliding member to fix the pipeline to both sides of the telescopic slide frame through the clasps. The telescopic slide frame has a corresponding communication space inside, and the circuit is arranged to pass through the communication space. The pipeline can be a corrugated pipe with a certain telescopic deformation amount, etc., and the circuit can be wound and arranged through a spiral spring provided inside the communication space. When the telescopic slide frame extends, the circuit is pulled out; when the telescopic slide frame contracts, the circuit is rewound under the restoring force of the spiral spring.

[0102] The first fixed seat 11 is used for fixedly connecting to the first component. A fixed connection portion is provided on the first fixed seat 11. Preferably, the fixed connection portion is configured as a plate-like structure and includes a plurality of through holes. It can be fixedly connected to the first component through connecting members such as bolts. A rotating connection portion is provided on the fixed connection portion for hinged connection with the first rotating seat 12.

[0103] Preferably, as Figures 1 - 4, as shown in FIGS. 10-14, for the convenience of pipeline installation and connection, 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 connection part, or a support plate can be provided on the fixed connection part, 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 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.

[0104] The first mounting seat 10 further includes a first rotating seat 12. The first rotating seat 12 is hinged to the first fixing seat 11. The first rotating seat 12 includes a main body portion, and the main body portion is configured as a narrow and long plate-like structure. On one side thereof, a first rotating base 121 cooperating with the rotating connection part on the first fixing seat 11 is provided. 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 part are rotationally connected through a rotating shaft, so that the first rotating seat 12 can rotate relative to the first fixing seat 11.

Clothing treatment equipment

[0116] The present invention also provides a laundry treatment device, which may be a washing machine or the like. As Figures 16 - 18 shown, the laundry treatment device includes:

[0117] A frame 2, on which a plurality of treatment barrel mounting positions are provided for mounting a laundry treatment barrel;

[0118] The laundry treatment barrel includes a drawer-type treatment barrel 1, which is slidably connected to the frame 2 and can be pulled out of 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 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.

[0119] Preferably: The pipeline installation structure is obliquely arranged between the drawer-type treatment barrel 1 and the frame 2. During the telescopic process, the telescopic structure rotates simultaneously in the horizontal direction. This inclined setting method can make the shortest distance between the drawer-type treatment barrel 1 and the frame 2 after being pushed in, and can make full use of the space between the two.

[0120] 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 pipeline installation structure moves with it to make the whole elongate or contract.

[0121] 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 pulling the drawer-type treatment barrel 1, the first rotating seat 12 and the second rotating seat 22 rotate, and at the same time the link structure 30 and the telescopic structure 40 elongate. When pushing the drawer-type treatment barrel 1, the first rotating seat 12 and the second rotating seat 22 reverse, and the link structure 30 and the telescopic structure 40 shorten.

[0122] Moreover, when the drawer-type treatment barrel 1 is pushed to the innermost position of the frame 2, both the link structure 30 and the telescopic structure 40 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 machine, smaller.

[0123] 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 strong and weak electric lines of the water inlet pipeline of the pulsator washing barrel are arranged on the link structure 30, and the drain pipeline is arranged on the telescopic structure 40. Preferably, bellows are used at the connections of the water inlet pipeline and the drain pipeline with the drawer-type treatment barrel 1 to prevent the connections from being pulled or excessively worn during the movement of the pipelines.

[0124] Furthermore, a reducing connector 70 is also provided on the water inlet pipe. As Figure 18 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 communicates with the inlet of the pulsator washing tub. When the incoming water flow passes from the inlet end 71 to the outlet end 72, the water inlet pressure can be reduced, avoiding the incoming water from impacting the pulsator flip cover and causing a large water inlet abnormal noise. Preferably, an installation portion 73 is also provided on the reducing connector 70 for the fixed installation of the reducing connector 70.

[0125] The present invention realizes the installation of pipelines or lines connecting between two moving parts through a pipeline installation structure, thereby avoiding the influence of movement on the pipelines and lines, and can also realize the separation of pipelines 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.

[0126] 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, setting manners 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.
