Specifically, the top spray arm 20 is connected to the second water outlet 104, and the side spray arm 30 is connected to the water diversion port 102; as shown in fig. 2 and fig. 3, the pipe assembly 10 further includes a branch pipe 13, the branch pipe 13 is connected to the water diversion port 102 of the main pipe 11, the branch pipe 13 is provided with a branch flow channel 107 and a third water outlet 108, the branch flow channel 107 is communicated with the main flow channel 105 through the water diversion port 102, the third water outlet 108 is communicated with the branch flow channel 107, and the side spray arm 30 is disposed at the third water outlet 108. Wherein, the branch pipe 13 and the main pipe 11 are combined to form an inner water pipe of the spraying device 100.

Based on this, in the pipe assembly 10 provided in the embodiment of the present application, when in operation, water flows into the main flow channel 105 through the water inlet 101 under the action of the washing pump and flows upward, one path of water flows to the first flow channel section 1061 and the second flow channel section 1062 through the first water outlet 103 in sequence, and then flows to the top spray arm 20 through the second water outlet 104, so that spraying is achieved through the top spray arm 20, and the other path of water flows to the branch flow channel 107 through the water diversion port 102, and then flows to the side spray arm 30 through the third water outlet 108, so that spraying is achieved through the side spray arm 30.

In the embodiment, the first pipe segment 121 is disposed in a bent manner with respect to the main pipe 11, so that the second pipe segment 122 can be located at the top of the main pipe 11, thereby facilitating the downward spraying operation of the top spray arm 20 assembled at the second water outlet 104.

In the pipe assembly 10 provided by the embodiment of the present application, the first pipe segment 121 is disposed in a bent manner with respect to the main pipe 11, the inner diameter width of the second pipe segment 122 is smaller than the inner diameter width of at least a part of the first pipe segment 121, and the cross-sectional area of the second pipe segment 122 is smaller than the cross-sectional area of at least a part of the first pipe segment 121; based on this, when the water flow in the main pipe 11 flows into the first pipe section 121 of the connecting pipe 12 through the first water outlet 103, because the first pipe section 121 is arranged in a bent manner relative to the main pipe 11, the flow direction of the water flow in the main pipe 105 needs to be changed when the water flow flows to the first pipe section 121 through the first water outlet 103, so as to receive a certain resistance, and the water flow flowing from the main pipe 11 to the connecting pipe 12 is buffered due to the bent arrangement; when the water flow in the first pipe section 121 flows into the second pipe section 122, the cross-sectional area of the second pipe section 122 is smaller than the cross-sectional area of at least a part of the first pipe section 121, so that the water flow to the second pipe section 122 is reduced compared with the first pipe section 121. So set up, wholly reduced the discharge of connecting pipe 12, thus, the during operation of spraying is realized in order to spout through top spray arm 20 to the discharge flow direction connecting pipe 12 in sprue 105, can force the rivers in sprue 105 to flow into lateral duct 13 through distributive port 102, and realize the work of spraying through side spray arm 30, thereby help improving discharge and the water pressure in lateral duct 13, and keep the water yield and the hydraulic stability in lateral duct 13, slow down the problem that the decompression appears in lateral duct 13, and then do benefit to the work of spraying that realizes side spray arm 30.

Moreover, the inner diameter width of the second pipe section 122 is smaller than at least part of the inner diameter width of the first pipe section 121, so that the effect that the sectional area of the second pipe section 122 is smaller than at least part of the sectional area of the first pipe section 121 is achieved, and thus the inner diameter thickness of the second pipe section 122 does not need to be reduced, so that the inner diameter thickness of the second pipe section 122 is not too small, the inner diameter wall thickness of the whole connecting pipe 12 is not too small, and the connecting pipe 12 can keep a certain water flow; with such an arrangement, the water flow of the connecting pipe 12 is reduced by reducing the inner diameter width of the second pipe section 122, so as to increase the water flow of the branch pipe 13, and thus, on the basis of increasing the water flow of the branch pipe 13, a certain water flow can still be maintained in the connecting pipe 12 without being too small, that is, the spraying operation of the top spray arm 20 is maintained.

In addition, for making certain flow and water pressure have in the lateral conduit 13, set up the reposition of redundant personnel muscle in trunk line 11 at present usually, through reposition of redundant personnel muscle with rivers reposition of redundant personnel in the trunk line 11 shunt to lateral conduit 13 in, it can make duct assembly 10 have higher design degree of difficulty and cost to be inevitable like this, and this application embodiment is through carrying out the shape design to connecting pipe 12, save the design and the use of reposition of redundant personnel muscle, can simplify duct assembly 10's structure, thereby effectively reduce duct assembly 10's the design degree of difficulty and cost.

Therefore, the pipeline assembly 10 provided by the embodiment of the application enables the connecting pipe 12 and the branch pipes 13 to have appropriate water flow and water pressure stability, so that the spraying work of the top spray arm 20 and the side spray arms 30 is facilitated, and the pipeline assembly 10 is simple in structure and low in design difficulty and cost; accordingly, the spraying device 100 and the dishwasher provided by the embodiment of the present application also have the advantages of high stability of water flow and water pressure in the branch pipe 13, good spraying effect of the top spraying arm 20 and the side spraying arm 30, and low cost.

In one embodiment, referring to fig. 4 and 5 together, the inner diameter width of the first pipe segment 121 is configured to gradually decrease from the end far away from the second pipe segment 122 to the second pipe segment 122, and it can be understood that the width of the first flow passage segment 1061 gradually decreases from the end far away from the second flow passage segment 1062 to the second flow passage segment 1062, that is, the width of the first flow passage segment 1061 gradually decreases in the water flow direction of the first flow passage segment 1061. Based on this, in the process that the water flows from the first pipe section 121 to the second pipe section 122, the flow rate is gradually reduced without suddenly decreasing, so that the water pressure in the connecting pipe 12 has better stability, which is beneficial to the stability of the spraying operation of the top spray arm 20 on one hand, and on the other hand, the problem that the connecting pipe 12 is damaged by the water flow due to unstable water pressure is alleviated. Of course, in other embodiments of the present application, the first tube segment 121 and the second tube segment 122 may be configured such that the inner diameter width thereof is uniform, and the inner diameter width of the first tube segment 121 is greater than the inner diameter width of the second tube segment 122.

With reference to fig. 4 and fig. 5, two opposite inner sidewalls of the first pipe section 121 along the width direction are tapered from one end away from the second pipe section 122 to the second pipe section 122, and the first pipe section 121 is symmetrically disposed about a central axis of the first pipe section 121 extending along the length direction, so that the first pipe section 121 is of an axisymmetric structure; the central axis of the first pipe segment 121 is perpendicular to the width direction of the first pipe segment 121 and is arranged along the length direction of the first pipe segment 121. It is to be understood that the first flow channel section 1061 is tapered toward the second flow channel section 1062 from an end away from the second flow channel section 1062 along opposite sides in the width direction, and the first flow channel section 1061 is symmetrically disposed about the central axis along the opposite sides in the width direction. Based on this for relative bilateral symmetry setting along the width direction in first pipe section 121, then when the rivers in first pipe section 121 flow to second pipe section 122, the rivers in first pipe section 121 assemble to the centre gradually, can further improve the flow stability of rivers like this to improve the water pressure stability of first pipe section 121, and then do benefit to the stable work of spraying that realizes top spray arm 20.

In one embodiment, referring to fig. 4 to 5, the connecting tube 12 further includes a third tube segment 123, and the third tube segment 123 is configured to be disposed between the first water outlet 103 and the first tube segment 121; the third pipe section 123 is curved, and an inner wall of the third pipe section 123 is an arc surface. It is understood that the third pipe section 123 has a third flow channel segment 1063 therein, and the third flow channel segment 1063 is connected to the first flow channel segment 1061 and is connected to the main flow channel 105 through the first water outlet 103; the inner wall of the third flow channel section 1063 is a circular arc surface.

Based on this, the inner wall of the third pipe section 123 is an arc surface, which can better guide the water flow, and reduce the resistance when the water flow flows, so that the water flow in the main flow channel 105 can smoothly change the flow direction to flow to the first pipe section 121. In addition, when the flow direction of the water flow is changed, a certain resistance is applied to the water flow to obtain buffering, and the flow rate of the water flow when the first pipe section 121 flows is gradually reduced, so that if the first pipe section 121 is directly connected to the main pipe 11 and is arranged in a bending manner relative to the main pipe 11, so that the inner diameter width of the bent part of the first pipe section 121 relative to the main pipe 11 is also gradually reduced, the water flow rate flowing from the main pipe 105 into the first pipe section 121 is suddenly reduced, which is not beneficial to maintaining the water pressure stability of the connecting pipe 12, and further leads to the occurrence of pressure loss; in this embodiment, based on the arrangement of the third pipe segment 123, the water in the main flow channel 105 flows to the third pipe segment 123 through the first water outlet 103, and after the flow direction in the third pipe segment 123 is changed, the water in the third pipe segment 123 flows to the first pipe segment 121 and the second pipe segment 122 in sequence when being in a stable state, so as to gradually achieve the effect of reducing the flow rate, and facilitate to maintain the stability of the water pressure in the connection pipe 12.

In one embodiment, referring to fig. 4 and 6, at least a portion of second tube segment 122 is disposed in a curved configuration with respect to first tube segment 121.

On this basis, the second water outlet 104 is made to have a proper orientation, which is beneficial to realizing the downward spraying work of the top spray arm 20 assembled at the second water outlet 104; wherein the direction of the water flow in the second pipe section 122 is changed in the bending position. And, so set up for rivers are realizing the effect that reduces the flow through the width design, and its flow stability back, and the change of flow direction is realized through crooked design to the rethread, prevent that rivers from realizing the reduction of its flow through the width design simultaneously and realizing the change of its flow direction through crooked design, with the phenomenon that leads to the discharge in the connecting pipe 12 to reduce suddenly, so the design of this embodiment still helps keeping the water pressure stability in the connecting pipe 12.

Specifically, the second tube segment 122 includes a first branch tube segment 1221 and a second branch tube segment 1222, the first branch tube segment 1221 is disposed between the first tube segment 121 and the second branch tube segment 1222, and the second branch tube segment 1222 is bent with respect to the first branch tube segment 1221; alternatively, the second tube section 122 is arranged bent relative to the first tube section 121.

In one embodiment, referring to FIG. 4, the curvature of the second pipe segment 122 relative to the first pipe segment 121 is less than the curvature of the first pipe segment 121 relative to the main pipe 11. Because of this, the resistance to the water flow at the bending position between the second pipe segment 122 and the first pipe segment 121 is smaller than the resistance to the water flow at the bending position between the main pipe 11 and the first pipe segment 121, that is, the water flow is prevented from being excessively resisted after the flow rate of the water flow is reduced, which helps to provide better stability of the water pressure in the connection pipe 12.

In one embodiment, the inner wall of the junction of the second tube section 122 and the first tube section 121 is configured as a smooth transition. The arrangement is such that water in the first pipe section 121 can flow along the inner wall of the joint of the first pipe section 121 and the second pipe section 122 to the second pipe section 122, which helps to reduce the resistance to water flow.

In an embodiment, referring to fig. 1, 6 and 7, the bending plane formed by bending the second pipe section 122 relative to the first pipe section 121 and the bending plane formed by bending the first pipe section 121 relative to the main pipe 11 are perpendicular to the width direction of the connecting pipe 12; so set up for trunk line 11 and connecting pipe 12 are all laid through the inner wall that the ascending lateral wall of thickness side is pasting inner bag 200, make the overall arrangement of duct assembly 10 in inner bag 200 more reasonable like this, and then have improved inner bag 200's space utilization, make inner bag 200 have more spaces that are used for placing the bowl basket, so help realizing the miniaturized design of volume of dish washer.

The second water outlet 104 is provided at one side of the second pipe section 122 facing the main pipe 11 along the thickness direction, and the locking hole 109 is provided at the other side of the second pipe section 122 opposite to the second water outlet 104 along the thickness direction, and the locking hole 109 is configured to allow an external locking member to assemble the second pipe section 122 to the inner container 200 of the dishwasher. Based on this, by the arrangement of the locking hole 109, a stable and reliable assembling effect of the connecting pipe 12 and the inner container 200 can be realized; moreover, when the pipe assembly 10 is used, the second water outlet 104 is located below the second pipe section 122, and the locking hole 109 is located above the second pipe section 122, so that when stable assembly of the pipe assembly 10 and the liner 200 is realized, water flow in the second pipe section 122 basically flows from the second water outlet 104 to the top spray arm 20 under the action of gravity, and thus the problem that water flows out of the connecting pipe 12 through the locking hole 109 can be alleviated.

In one embodiment, referring to fig. 2 and 6, the first pipe segment 121 is connected separately from the main pipe 11. Based on this, when producing pipeline assembly 10, main pipe 11 and connecting pipe 12 separately carry out the injection moulding, promptly connecting pipe 12 is injection moulding alone, does benefit to the shape and the structural strength of controlling connecting pipe 12 and main pipe 11 like this.

In one embodiment, referring to fig. 1 and fig. 6, a concave space 201 is formed on a concave inner top wall of the inner container 200; at least part of the first pipe segment 121 is disposed in the concave space 201, or at least part of the second pipe segment 122 is disposed in the concave space 201, or at least part of the first pipe segment 121 and at least part of the second pipe segment 122 are both disposed in the concave space 201. So set up, help reducing the occupation space of pipe assembly 10 in inner bag 200 for the overall arrangement of pipe assembly 10 in inner bag 200 is more reasonable, and then has improved the space utilization of inner bag 200, so that inner bag 200 has more spaces that are supplied to placing the bowl basket.
