embodiments have no limitations on the present invention, and any transformations of

structure, method, or function made by persons skilled in the art according to these

embodiments fall within the protection scope of the present invention.

intended to include different orientations of the device in use or operation other than the

orientations shown in the drawings.

[00301 As shown in FIGS. 1 to 4, a first embodiment of the present invention

discloses a water pipeline integrated device mounted in a cabinet 90 of a refrigeration

appliance, wherein the water pipeline integrated device includes a filter 10, a water valve 20

and a water bottle 30 which are communicated, the filter 10 is provided with a water inlet

pipe 11, the water bottle 30 is provided with a water-bottle water outlet pipe 31, and the water

valve 20 is provided with an ice-making water supply pipe 21. A rear wall of the cabinet 90 is

provided with a through hole 91 communicated with the outside of the refrigeration appliance

and a water pipe mounting structure 92, and the water pipe mounting structure 92 includes a

pre-embedded pipe 93 provided in the through hole 91 and a protection pipe 94 provided in

the pre-embedded pipe 93. The protection pipe 94 is provided with at least three water pipe

holes 95 corresponding to the water inlet pipe 11, the water-bottle water outlet pipe 31 and

the ice-making water supply pipe 21.

[0031] In the water pipeline integrated device according to the present invention, water pipes on the filter 10, the water bottle 30 and the water valve 10 penetrate through the

protection pipe 94, and the protection pipe 94 is fitted with the pre-embedded pipe 93, such

that the protection pipe 94 enables the plural water pipes to be provided in different water

pipe holes 95 respectively, and the water pipes can be tidied; in addition, the protection pipe

94 is provided between the pre-embedded pipe 93 and the water pipes, and therefore, a sealing effect can be achieved to prevent cold air in the cabinet from leaking to the outside.

[0032] Further, the pre-embedded pipe 93 is in interference fit with the protection pipe 94. The interference fit connection mode is simple, and a sealing effect between the pre-embedded pipe 93 and the protection pipe 94 is good.

[0033] Preferably, the protection pipe 94 includes an inlet portion 96 and a fitting portion 97 connected with each other, and the water pipe hole 95 is formed in the fitting portion 97. An outer diameter of the inlet portion 96 is greater than an outer diameter of the fitting portion 97, and the pre-embedded pipe 93 is in interference fit with thefitting portion 97. Specifically, the pre-embedded pipe 93 is placed at a corresponding position on the cabinet 90 before the cabinet is foamed, and after the foaming is completed, the position of the pre-embedded pipe 93 is fixed. Then, The protection pipe 94 is mounted in the pre-embedded pipe 93, and in the mounting process, the fitting portion 97 of the protection pipe 94 entirely enters the pre-embedded pipe 93 and is in interference fit with the pre-embedded pipe 93, and a part of the inlet portion 96 can protrude out of the pre-embedded pipe 93. The water inlet pipe 11, the water-bottle water outlet pipe 31 and the ice-making water supply pipe 21 can enter the protection pipe 94 from the inlet portion 96, penetrate into the water pipe holes 95 and then penetrate out of the cabinet 90. In this way, the inlet portion 96 of the protection pipe 94 can be easily inserted into the pre-embedded pipe 93 and tightly fitted therewith.

[0034] In the embodiment of the present invention, an outer wall of the fitting portion 97 is provided with a convex ring 98 in a circumferential direction, and a sum of radial sizes of the protection pipe 94 and the convex ring 98 is greater than an inner diameter of the pre-embedded pipe 93. By providing the convex ring 98, the protection pipe 94 can be in interference fit with the pre-embedded pipe 93.

[0035] Further, a plurality of convex rings 98 are provided on the outer wall of the fitting portion 97 in a length direction. The plurality of convex rings 98 may enhance the sealing effect.

[0036] Preferably, the convex ring 98 is made of an elastic material. Thus, when the protection pipe 94 is mounted inside the pre-embedded pipe 93, the convex ring 98 can be pressed to deform, such that the fitting portion 97 can enter the pre-embedded pipe 93 relatively easily.

[00371 In the first embodiment of the present invention, a plurality of drawers are provided in the cabinet 90, and the filter 10 is provided between two of the drawers arranged

side by side. The water pipeline integrated device further includes a fixed housing 80 for

accommodating the water bottle 30 and the water valve 20, and the fixed housing 80 is

provided below the filter 10 and connected to the rear wall of the cabinet 90. The filter 10 is

provided between the drawers, such that a cartridge is convenient to replace. The water bottle

and the water valve 20 can be sealed to guarantee use safety.

[00381 In addition, a water circuit in the present invention is as follows: tap water of a user is connected with a one-outlet one-water valve of a compressor bin of a refrigerator, and

enters the filter 10 through the water inlet pipe 11 to be purified, the purified water enters the

water valve 20 through a filter water outlet pipe 12 for flow division (the water valve 20 is

configured as a one-outlet dual-water valve), and the water in one path enters an ice maker

through the ice-making water supply pipe 21; the water in the other path enters the water

bottle 30, cold water stored in the water bottle 30 reaches an external water fetching module

(such as a dispenser) on a door through the water-bottle water outlet pipe 31.

[00391 Further, the fixed housing 80 includes an upper side plate 81, the filter 10 is

further provided with the filter water outlet pipe 12, and the water inlet pipe 11 and the filter

water outlet pipe 12 extend along the upper side plate 81; the upper side plate 81 is provided

with a fixed portion 82 extending upwards, and the fixed housing 80 is connected to the rear

wall of the cabinet 90 by the fixed portion 82. A position of the upper side plate 81

corresponding to the fixed portion 82 is provided with a downwards concave escaping groove

83 and a baffle 84 parallel to the upper side plate, a gap is formed between the escaping

groove 83 and the baffle 84, and the water inlet pipe 11 and the filter water outlet pipe 12

penetrate through the gap.

[0040] Since a screw is required to penetrate through the fixed portion 82 to fasten the

fixed housing 80 and the cabinet 90, in order to prevent the screw from damaging the water

inlet pipe 11 and the filter water outlet pipe 12, the baffle 84 for protecting the water pipe is

designed on the fixed housing 80, and the escaping groove 83 is provided on the upper side

plate 81, such that the water inlet pipe 11 and thefilter water outlet pipe 12 can penetrate below the baffle, that is, penetrate through the gap between the baffle and the escaping groove.

[0041] In addition, a plurality of snapping parts 85 are provided on the fixed housing , and the water-bottle water outlet pipe 31 and the ice-making water supply pipe 21 are snapped to the snapping parts 85 respectively. The water pipes can be fixed by the snapping parts 85 on the fixed housing 80, such that the water pipes can be arranged along fixed directions, and a water pipe bending possibility is reduced.

[0042] Preferably, the water pipeline integrated device further includes a water valve support 22 fixedly connected with the water valve 20, and the water valve 20 is mounted on the fixed housing 80 through the water valve support 22. After the water valve support 22 is mounted to the fixed housing 80, the water valve support 22 and the fixed housing 80 may wrap the water valve 20. When the water valve is mounted, the water valve 20 is first mounted on the water valve support 22, and then, the water valve support 22 is entirely mounted on the fixed housing 80, such that the water valve 20 can be wrapped by the water valve support 22 and the fixed housing 80 from two directions, the water valve 20 can be protected while the mounting process is simple, and the water valve is prevented from being collided or wetted by water.

[0043] In addition, as shown in FIG. 2, since the water valve 20 is configured as an electromagnetic valve, when the water valve is frequently opened and closed, heat is generated, and in order to avoid that the water-bottle water outlet pipe 31 is too close to the water valve 20 to cause a scald, a part of the water-bottle water outlet pipe 31 is thermally bent and shaped, such that the water-bottle water outlet pipe bypasses the water valve 20 and is fixed by the snapping part 85 at a bottom of the fixed housing 80.

[0044] As shown in FIG. 2, two fixed portions 82 are provided at a top of thefixed housing 80, two screws are used to penetrate through the fixed portions 82 to fasten the fixed portions to the cabinet 90, two clamping jaws 86 are provided at the bottom of the fixed housing 80, two clamping grooves are provided at corresponding positions of the cabinet 90, and the fixed housing is assembled to the cabinet by clamping the two clamping jaws 86 provided at the bottom of the fixed housing 80 into the clamping grooves. Meanwhile, a front cover is provided, the fixed housing 80 is decorated by the front cover, and the water valve and the water bottle can be wrapped in the fixed housing. The front cover and the fixed housing 80 are fastened by the screws, so as to ensure that detachment cannot be performed without using a tool by the user, thereby guaranteeing the use safety.

[0045] As shown in FIGS. 5 to 9, in a second embodiment of the present invention, unlike the first embodiment, the filter 100, the water bottle 300, and the water valve 200 are mounted onto the fixed housing 800, and the fixed housing 800 wraps the filter 100 and the water valve 200. The water inlet pipe 11, the water-bottle water outlet pipe 31, the ice-making water supply pipe 21 and the water pipe mounting structure 92 in the second embodiment are the same as the water inlet pipe 11, the water-bottle water outlet pipe 31, the ice-making water supply pipe 21 and the water pipe mounting structure 92 in the first embodiment, and are not repeated herein.

[00461 As shown in FIG. 5, the water bottle 300 includes a proximal end 310 and a distal end 320 arranged oppositely in a length direction, the proximal end 310 of the water bottle 300 is detachably connected with the water valve 200 by a water-bottle water inlet assembly 400, and the distal end 310 of the water bottle 300 is detachably connected with the filter 100 by a distal-end snapping assembly 500. The water-bottle water inlet assembly 400 includes a rotation axis perpendicular to a length direction of the water bottle 300. During snapped connection of the distal-end snapping assembly 500, the water-bottle water inlet assembly 400 realizes locked connection in an axial direction of the rotation axis. When the water-bottle water inlet assembly 400 is released in the axial direction of the rotation axis, the distal-end snapping assembly 500 is released from the snapped connection.

[00471 In the water pipeline integrated device according to the second embodiment of the present invention, one end of the water bottle 300 is detachably connected with the water valve 200 by the water-bottle water inlet assembly 400, and the other end of the water bottle is detachably connected with the filter 100 by the distal-end snapping assembly 500, such that during snapped connection of the distal-end snapping assembly 500, the water-bottle water inlet assembly 400 also realizes locked connection, and the water bottle 300, the water valve 200 and the filter 100 can be connected together. When the water-bottle water inlet assembly 400 is released, the distal-end snapping assembly 500 is just released from the snapped connection, such that the water bottle 300 can be smoothly detached from the water valve 200 and the filter 100. Therefore, the water bottle 300 can be conveniently connected with or detached from the water valve 200 and the filter 100 by fitting of the water-bottle water inlet assembly 400 and the distal-end snapping assembly 500, such that the water bottle 300 can be conveniently replaced or repaired subsequently.

[00481 Further, when the distal-end snapping assembly 500 is released from the snapped connection, the water-bottle water inlet assembly 400 is released in the axial direction of the rotation axis. That is, when the distal-end snapping assembly 500 is released from the snapped connection, the water-bottle water inlet assembly 400 is also released in the axial direction of the rotation axis, and at this point, the water bottle 300 can be detached from the water valve 200 and the filter 100. Thus, state transitions of the water-bottle water inlet assembly 400 and the distal-end snapping assembly 500 are completely consistent, such that a stroke of a rotation operation can be shortened, and an operation of mounting or dismounting the water bottle 300 is simpler and more convenient.

[0049] In the second embodiment of the present invention, during snapped connection of the distal-end snapping assembly 500, a direction of the locked connection of the water-bottle water inlet assembly 400 is different from a direction of the snapped connection of the distal-end snapping assembly 500. That is, the water-bottle water inlet assembly 400 and the distal-end snapping assembly 500 are connected with the water bottle in different directions, thereby further reinforcing the connection of the water bottle 300 with the water valve 200 and the filter 100; the connection in the two different directions does not interfere, such that the water bottle 300 is not easily released and dropped even when the assembly in one direction fails.

[0050] Still further, during snapped connection of the distal-end snapping assembly 500, the direction of the locked connection of the water-bottle water inlet assembly 400 is the axial direction of the rotation axis, and the direction of the snapped connection of the distal-end snapping assembly 500 is perpendicular to the axial direction of the rotation axis. That is, directions of the connection of the water-bottle water inlet assembly 400 and the distal-end snapping assembly 500 to the water bottle are perpendicular to each other. Mutual interference of the connection in the two directions can be reduced to the minimum, such that the connection of the water bottle is firmer.

[0051] In the second embodiment of the present invention, the distal-end snapping assembly 500 includes a distal-end snapping portion and a distal-end fitting portion which can be snapped to or separated from the distal-end snapping portion, the distal-end snapping portion is provided on one of the water bottle 300 and the filter 100, and the distal-end fitting portion is provided on the other of the water bottle 300 and the filter 100. The snapping or separating operation can be easily realized by mutual fitting of the distal-end snapping portion and the distal-end fitting portion. In the present embodiment, the distal-end snapping portion is provided on the filter 100, and the distal-end fitting portion is provided on the water bottle 300.

[0052] Further, as shown in FIG. 6, the distal-end snapping portion is configured as a distal-end hanging buckle 510 provided on the filter 100, the distal-end fitting portion is configured as a distal-end hanging hole 520 provided on the water bottle 300, and during the snapped connection of the distal-end snapping assembly 500, the distal-end hanging buckle 510 is inserted into the distal-end hanging hole 520. The connection by the hanging buckle and the hanging hole has a simple structure and a low cost, and is easy to operate. Specifically, the snapped connection of the distal-end snapping assembly 500 may be realized directly by inserting the distal-end hanging buckle 510 into the distal-end hanging hole 520. When the connection of the distal-end snapping assembly 500 is desired to be reinforced, a thread may be provided in the distal-end hanging buckle 510, and when the distal-end hanging buckle 510 is inserted into the distal-end hanging hole 520, a screw is screwed into and in threaded connection with the distal-end hanging buckle 510, and an end surface of the screw abuts against an edge of the hanging hole 520. In other embodiments, the distal-end hanging buckle may also be in interference fit with the distal-end hanging hole. Therefore, in a transportation/assembly process of the water pipeline integrated device or a refrigerator, even when conditions of collision or shaking, or the like, are generated, the distal end of the water bottle can not be easily disconnected. Also, the distal-end hanging buckle 510 may extend outwards from a housing of the filter 100, the distal-end hanging buckle 510 and the housing of the filter 100 may be integrally formed, the distal-end hanging hole 520 may extend outwards from the water bottle 300, and the distal-end hanging hole 520 and the water bottle 300 may be integrally formed. The arrangement of the integrally formed structure makes the connection between the water bottle 300 and the filter 100 more stable and firmer.

[00531 In other embodiments, the distal-end snapping portion and the distal-end fitting portion may be of other structures in snapped connection.

[0054] Preferably, the proximal end 310 of the water bottle 300 is also detachably connected with the filter 100 by a proximal-end snapping assembly 600. During snapped connection of the distal-end snapping assembly 500, the proximal-end snapping assembly 600 realizes snapped connection. When the water-bottle water inlet assembly 500 is released in the axial direction of the rotation axis, the proximal-end snapping assembly 600 is released from the snapped connection. The proximal-end snapping assembly 600 is provided at the proximal end 310 of the water bottle 300, thereby further strengthening the connection at the proximal end 310 of the water bottle 300. Furthermore, the proximal-end snapping assembly 600 can also be fitted with the water-bottle water inlet assembly 400 and the distal-end snapping assembly 500 to realize synchronous connection or detachment. Specifically, the proximal-end snapping assembly 600 also includes a proximal-end snapping portion 610 and a proximal-end fitting portion 620 which can be snapped to or separated from the proximal-end snapping portion 610, and in the embodiment of the present invention, the proximal-end snapping portion is configured as a proximal-end hanging buckle 610, and the proximal-end fitting portion is configured as a proximal-end hanging hole 620.

[0055] As shown in FIGS. 5 to 8, the water bottle 300 and the water valve 200 are also selectively communicated by the water-bottle water inlet assembly 400, and the water-bottle water inlet assembly 400 includes: a water inlet sleeve 410 and a water inlet insertion part 420 rotatably inserted into the water inlet sleeve 410. The water inlet insertion part 420 and the water inlet sleeve 410 are provided therein with water inlet flow channels which can be communicated with each other. The water inlet sleeve 410 is provided on one of the water bottle 300 and the water valve 200, and the water inlet insertion part 420 is provided on the other of the water bottle 300 and the water valve 200. The water inlet insertion part 420 is provided with a water inlet limiting protrusion 421, and the water inlet sleeve 410 includes a water inlet cylinder 411, a water inlet insertion port 412 formed on the water inlet cylinder 411 and a water inlet limiting hole 413 provided in a circumferential direction of the water inlet cylinder 411. The water inlet sleeve 410 is further provided with a water inlet guide groove 414 matched with the water inlet limiting protrusion 421, and the water inlet guide groove 414 extends axially from the water inlet insertion port 412 along the water inlet sleeve 410 and is communicated with an end portion of the water inlet limiting hole 413. As shown in FIG. 5, in the circumferential direction of the water inlet cylinder 411, a dimension H of the water inlet limiting hole 413 is greater than a dimension L of the water inlet guide groove 414. That is, the water-bottle water inlet assembly 400 not only serves to connect the water bottle 300 and the water valve 200, but also serves to allow water to pass therethrough, that is, allow water in the water valve 200 to flow into the water bottle 300, after the connection. In the embodiment of the present invention, external water firstly flows into the filter 100, and then flows into the water valve 200 from the filter 100, the water valve

200 has two water outlets, one of the two water outlets extends outwards to form the water

inlet insertion part 420, and an inlet of the water bottle 300 extends outwards to form the

water inlet sleeve 410, such that the water can flow through the water inlet insertion part 420

and the water inlet sleeve 410 after the water inlet insertion part 420 and the water inlet

sleeve 410 are connected.

[00561 In addition, in the circumferential direction of the water inlet cylinder 411, the dimension H of the water inlet limiting hole 413 is set to be greater than the dimension L of

the water inlet guide groove 414, such that when the water inlet insertion part 420 is inserted

into the water inlet sleeve 410, the water inlet limiting protrusion 421 on the water inlet

insertion part 420 can enter the water inlet guide groove 414 from the water inlet insertion

port 412 on the water inlet sleeve 410, and then, the water bottle 300 is rotated along the

rotation axis in a first direction, and the water inlet limiting protrusion 421 can enter the

water inlet limiting hole 413; since the dimension H of the water inlet limiting hole 413 is

larger and the water inlet limiting hole 413 is not communicated with the water inlet insertion

port 412, at this point, the water inlet limiting protrusion 421 and the water inlet limiting hole

413 are in snap fit, such that even when a force is applied in a direction opposite to an

insertion direction, the water inlet insertion part 420 cannot reversely exit from the water inlet

sleeve 410, thereby locking the water-bottle water inlet assembly 400. Then, the water bottle

300 is rotated along the rotation axis in a direction opposite to the first direction, such that the

water inlet limiting protrusion 421 is aligned with the water inlet guide groove 414, thereby releasing the water-bottle water inlet assembly 400 in the axial direction of the rotation axis.

At this point, the water inlet limiting protrusion 421 can move towards the water inlet

insertion port 412 along the water inlet guide groove 414 by applying a force in the direction

opposite to the insertion direction, and finally, the water inlet insertion part 420 reversely

exits from the water inlet sleeve 410.

[00571 Specifically, as shown in FIG. 7, the rotation axis is configured as a central axis X of the water inlet sleeve 410. That is, by rotating the water bottle 300 about the central

axis X of the water inlet sleeve 410, the water-bottle water inlet assembly 400 can be locked

or released, and the distal-end snapping assembly 500 can realize snapped connection or be

released from the snapped connection. Thus, the connection and detachment of the water

bottle 300 are simple, and an operation of a user is convenient.

[0058] Further, the water inlet sleeve 410 extends outwards from a water inlet of the

water bottle 300, and the water inlet sleeve 410 and the water bottle 300 are integrally

formed. The water inlet insertion part 420 extends outwards from a water outlet of the water

valve 200, and the water inlet insertion part 420 and the water valve 200 are integrally

formed. That is, no water pipe is provided between the water bottle 300 and the water valve

200, and the water bottle 300 and the water valve 200 are directly connected through the

water-bottle water inlet assembly 400 extending from the respective components of the water

bottle 300 and the water valve 200, such that the connection is more stable, and a problem

that the water pipe is bent to be damaged and difficult to repair, and a risk of water leakage

are avoided.

[0059] Preferably, the water inlet insertion part 420 includes a first insertion portion

422 and a second insertion portion 423 provided at a front end of the first insertion portion

422, and an outer diameter of the second insertion portion 423 is less than an outer diameter

of the first insertion portion 422. When the water inlet insertion part 420 is inserted into the

water inlet sleeve 410, the second insertion portion 423 having a less inner diameter is

inserted into the water inlet sleeve 410 first, such that a guiding function can be provided for

an insertion action, and the connection of the water-bottle water inlet assembly 400 is easier.

[0060] In the embodiment of the present invention, a sealing part is fitted over the

second insertion portion 423. The sealing part 4231 is configured to fill a gap between an outer wall of the second insertion portion 423 and an inner wall of the water inlet sleeve 410, thereby preventing water leakage. Specifically, an inner diameter at a position of the water inlet sleeve 410 corresponding to the sealing part 4231 on the second insertion portion 423 is reduced, such that the sealing part 4231 is pressed between the inner wall of the water inlet sleeve 410 and the second insertion portion 423 to further enhance a sealing effect.

[0061] Further, the water inlet insertion part 420 further includes a stopper 424 connected with the first insertion portion 421, and an end surface of the stopper 424 abuts

against an end surface of the water inlet sleeve 410. The stopper 424 serves as a terminal

point of insertion of the water inlet insertion part 420 into the water inlet sleeve 410; that is,

when the water inlet insertion part 420 is inserted into the water inlet sleeve 410, and the end

surface of the stopper 424 is seen to abut against the end surface of the water inlet sleeve 410,

the insertion action can be determined to be in place.

[0062] As shown in FIG. 8, the water inlet insertion part 420 is provided with two

water inlet limiting protrusions 421, the two water inlet limiting protrusions 421 are

symmetrically arranged relative to an axis of the water inlet insertion part 420, and two water

inlet guide grooves 413 are arranged at positions on the water inlet sleeve corresponding to

the two water inlet limiting protrusions 421. The two symmetrical water inlet limiting

protrusions 421 and the two corresponding water inlet guide grooves 413 are arranged, such

that the water inlet insertion part 420 and the water inlet sleeve 410 can be locked more

firmly and stably.

[0063] Preferably, the filter 100 and the water valve 200 are selectively communicated through a filter water outlet assembly 700. The filter water outlet assembly

700 includes: a water outlet sleeve 710 and a water outlet insertion part 720 rotatably inserted

into the water outlet sleeve 710. The filter water outlet assembly 700, the water outlet sleeve

710 and the water outlet insertion part 720 have identical structures to and different positions

from the water-bottle water inlet assembly 400, the water inlet sleeve 410 and the water inlet

insertion part 420. Therefore, the detailed structure of the filter water outlet assembly 700 is

not repeated.

[0064] Further, the filter 100, the water valve 200 and the water bottle 300 are

adjacently arranged two by two, and the water-bottle water inlet assembly 400 is perpendicular to the filter water outlet assembly 700. That is, the central axis X of the water outlet sleeve 710 is perpendicular to the central axis of the water inlet sleeve 410.

[0065] Specifically, the fixed housing 800 also functions to connect the water pipeline integrated structure to the refrigerator. In addition, the distal-end hanging buckle 510 is also

provided on the fixed housing 800, such that the connection of the water bottle 300 is more

stable.

[00661 An embodiment of the present invention further discloses a refrigeration appliance including a refrigerating chamber, wherein the refrigerating chamber is provided

therein with the water pipeline integrated device as mentioned above.
