[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0061] Please refer to Figure 1 to Figure 2 The present application proposes a dishwasher, which is a device that can automatically wash tableware.

[0062] The dishwasher comprises a housing (not shown in the figure), an inner tank (not shown in the figure) and a spray device 100. The inner tank is arranged in the housing and has a washing cavity, and the washing cavity is used for placing tableware. The spray device 100 is located in the washing cavity and can spray a fluid into the washing cavity to clean the tableware in the washing cavity through the fluid.

[0063] Please refer to Figures 1 to 3 Further, the spray device 100 includes a water inlet pipe 10, a water inlet valve 50 and a spray arm 30. It can be understood that the water inlet pipe 10, the water inlet valve 50 and the spray arm 30 are connected in sequence, so that the fluid first flows into the water inlet pipe 10, then flows from the water inlet pipe 10 to the water inlet valve 50, and then flows from the water inlet valve 50 to the spray arm 30, and finally sprayed out through the spray arm 30 to clean the tableware in the washing chamber.

[0064] The water inlet pipe 10 is arranged in a long tube shape. The water inlet pipe 10 can not only transport the fluid to the water inlet valve 50 , but also install the water inlet valve 50 .

[0065] The water inlet valve 50 is a component for regulating the flow direction and flow rate of the fluid. The water inlet valve 50 may be made of plastic materials such as pp (polypropylene) to have advantages such as better corrosion resistance and easy molding.

[0066] The water inlet valve 50 includes a valve body 51 and a rotating shaft portion 53. The valve body 51, as the main structure of the water inlet valve 50, is configured to regulate the flow direction and flow rate of the fluid, wherein the valve body 51 is connected to the spray arm 30. The rotating shaft portion 53 is a component for transporting the fluid flowing out of the water inlet pipe 10 to the valve body 51. Specifically, one end of the rotating shaft portion 53 is connected to the water inlet pipe 10, and the other end is connected to the valve body 51. In this way, the fluid flowing out of the water inlet pipe 10 will first flow to the rotating shaft portion 53, and then flow from the rotating shaft portion 53 to the valve body 51. In addition, one end of the rotating shaft portion 53 is also rotatably connected to the water inlet pipe 10, and the other end is also fixedly connected to the valve body 51, so that the rotating shaft portion 53 can drive the valve body 51 to rotate, that is, the relative rotation of the water inlet valve 50 and the water inlet pipe 10 is realized.

[0067] The valve body 51 and the rotating shaft 53 can be an integral component, so that the water inlet valve 50 as a whole has a better structural strength to withstand the strong impact of the fluid, and can also reduce the assembly steps of the valve body 51 and the rotating shaft 53, thereby improving the assembly efficiency. Of course, in other embodiments, the valve body 51 and the rotating shaft 53 can also be separate components, so as to facilitate the replacement or maintenance of the rotating shaft 53 or the valve body 51 separately, and this embodiment does not limit this.

[0068] The spray arm 30 is a component for spraying fluid into the washing chamber. It can be arranged in a generally long strip shape, and the material of the spray arm 30 can be a plastic material such as pp (polypropylene) to have advantages such as better corrosion resistance and light weight. The spray arm 30 has a spray chamber 31 and a spray hole 33. The spray hole 33 and the valve body 51 are respectively connected to the spray chamber 31. In this way, the fluid flowing into the valve body 51 will flow into the spray chamber 31 of the spray arm 30, and then be sprayed from the spray hole 33 toward the washing chamber.

[0069] In order to achieve easy installation of the water inlet pipe 10, the water inlet valve 50 and the spray arm 30, in this embodiment, the rotating shaft portion 53 is passed through the spray arm 30, and one end of the rotating shaft portion 53 is connected, and the other end is fixedly connected to the valve body 51, so that the spray arm 30 can be arranged between the water inlet pipe 10 and the valve body 51, and the spray arm 30 will drive the valve body 51 to rotate relative to the water inlet pipe 10.

[0070] In this way, during the actual installation process of the spray device 100 of this embodiment, the rotating shaft portion 53 fixedly connected to the valve body 51 can be first passed through the spray arm 30, and then the rotating shaft portion 53 can be connected to the water inlet pipe 10, thereby completing the installation of the water inlet pipe 10, the spray arm 30 and the water inlet valve 50, and the spray arm 30 is arranged between the water inlet pipe 10 and the valve body 51. In this way, the steps of fixedly connecting the water inlet valve 50 and the spray arm 30 can be reduced, which can not only effectively reduce the installation difficulty of the spray device 100, but also improve the installation efficiency of the spray device 100, and realize the simple and quick installation of the spray device 100 as a whole.

[0071] Please refer to Figures 2 to 3 In some embodiments, the shaft portion 53 includes a main body section 531 and a connecting section 533. It can be understood that the main body section 531 is the main part of the shaft portion 53. Specifically, the main body section is inserted through the spray arm 30, and on the basis of the main body section 531 being inserted through the spray arm 30, one end of the main body section 531 is fixedly connected and communicated with the valve body 51.

[0072] The connecting section 533 may be expanded in the direction from the main section 531 toward the water inlet pipe 10, so that the inner diameter of the connecting section 533 is larger than the inner diameter of the main section 531. The connecting section 533 is connected to the other end of the main section 531, and is connected and communicated with the water inlet pipe 10 to form a connection between the rotating shaft 53 and the water inlet pipe 10. The connecting section 533 and the main section 531 may be an integral component, so that water can be prevented from leaking outward from the joint between the two, and the connection strength between the two can be improved, and the assembly process can be reduced. Of course, the two can also be separate components and connected by bonding, clamping or screwing, etc., which is not limited in this embodiment.

[0073] Among them, the spray arm 30 is located between the connecting section 533 and the valve body 51. In this way, the spray arm 30 can be further limited between the connecting section 533 and the valve body 51, reducing the movement range of the spray arm 30 in the height direction of the spray device 100, which is beneficial to improving the stability of the spray arm 30 during operation.

[0074] Please refer to Figures 2 to 3 Furthermore, the spray arm 30 has a through hole 35 for the main body section 531 to pass through, wherein the shape of the through hole 35 can be circular. The connecting section 533 is located on the side of the through hole 35 close to the water inlet pipe 10, and the diameter of the valve body 51 is larger than the aperture of the through hole 35. In this way, the valve body 51 can support the spray arm 30 and can limit the spray arm 30. In this way, the spray arm 30 can be installed and the stability of the spray arm 30 during operation can be improved.

[0075] Please refer to Figures 2 to 3In some embodiments, the valve body 51 has a water inlet 511 and a water outlet 512, the water inlet 511 is connected to the main body section 531, and the water outlet 512 is connected to the spray arm 30, so that water will first flow from the main body section 531 to the water inlet 511, then flow to the water outlet 512, and finally flow into the spray chamber 31 of the spray arm 30.

[0076] Among them, the water outlet 512 is provided on the side of the valve body 51 facing the spray arm 30, and the water inlet 511 is farther away from the spray arm 30 than the water outlet 512, that is, the water outlet 512 is arranged closer to the spray arm 30. It can be understood that water can first flow from the main body section 531 penetrating the spray arm 30 to the water inlet 511 of the valve body 51 for limiting the spray arm 30, and then flow inside the valve body 51 in the opposite direction of the flow direction of the main body section 531 to the water outlet 512, and then flow into the spray chamber 31. In this way, while the valve body 51 can limit the spray arm 30, when the water flows inside the valve body 51, it can flow into the spray chamber 31 of the spray arm 30 with a shorter flow path, which helps to improve the flow efficiency. Of course, the present application is not limited thereto. In other embodiments, the water outlet 512 may be provided on the side wall of the valve body 51 , and the distance between the water outlet 512 and the spray arm 30 is equal to the distance between the water inlet 511 and the spray arm 30 .

[0077] See also Figure 3 Furthermore, the valve body 51 is annularly arranged and surrounded by an inner cavity 519, the water inlet 511 is opened in the cavity wall of the inner cavity 519, one end of the main body section 531 extends into the inner cavity 519 and communicates with the water inlet 511, and the other end of the main body section 531 extends out of the inner cavity 519 and passes through the spray arm 30 to be connected with the connecting section 533. In this way, when one end of the main body section 531 extends into the inner cavity 519, it can directly communicate with the water inlet 511 opened in the cavity wall of the inner cavity 519. Compared with the form in which the water inlet 511 is opened in the bottom wall of the valve body 51 or the outer wall of the valve body 51, it is easier to realize the communication operation between the water inlet 511 and the main body section 531, and it helps to shorten the flow path of water.

[0078] During the actual use of the spray device 100, the connecting section 533 of the rotating shaft portion 53 will rub against the water inlet pipe 10 when rotating relative to the water inlet pipe 10, so that during the long-term use of the spray device 100, the water inlet pipe 10 and the connecting section 533 will produce a certain degree of physical wear, resulting in the need to replace the water inlet pipe 10 and the rotating shaft portion 53. However, under normal circumstances, since the water inlet pipe 10 and the water inlet valve 50 are both integral components, it is necessary to replace the water inlet pipe 10 and the water inlet valve 50 as a whole, which is inconvenient to operate and has a high maintenance cost.

[0079] To solve this technical problem, please refer to Figures 2 to 3In some embodiments, the spray device 100 further includes a first connecting member 90 and a second connecting member 80 .

[0080] The first connecting member 90 and the second connecting member 80 can both be made of plastic materials such as POM (Polyoxymethylene), so that the first connecting member 90 and the second connecting member 80 have excellent friction resistance and effectively extend the service life of the two.

[0081] The connecting section 533 is sleeved on the first connecting member 90 and is detachably connected to the first connecting member 90. In this embodiment, the specific detachable connection form of the connecting section 533 and the first connecting member 90 may include one of a clamping connection and a screw connection. The second connecting member 80 is sleeved with the connecting section 533 and is detachably connected to the water inlet pipe 10. In this embodiment, the specific detachable connection form of the second connecting member 80 and the water inlet pipe 10 may include one of a clamping connection and a screw connection. The connecting section 533 is rotatable relative to the water inlet pipe 10.

[0082] In this way, during long-term use, if the physical wear of the first connecting member 90 and the second connecting member 80 is large, the first connecting member 90 can be directly removed from the connecting section 533 and replaced with a new first connecting member 90, without replacing the water inlet valve 50 as a whole. The second connecting member 80 can be directly removed from the water inlet pipe 10 and replaced with a new second connecting member 80, without replacing the water inlet pipe 10 as a whole. The operation is more convenient and can effectively reduce maintenance costs.

[0083] Please refer to Figures 3 to 5 In some embodiments, the first connecting member 90 is arranged in an annular shape, and the first connecting member 90 includes a first annular body 91 and a flange 93.

[0084] The first annular body 91 is the main part of the first connecting member 90, and its shape can be cylindrical, which is not limited in this embodiment. The first annular body 91 extends into the connecting section 533 and is engaged with the connecting section 533, so that the connection stability between the first annular body 91 and the connecting section 533 is ensured, and the two are easy to disassemble and assemble, thereby improving the assembly efficiency.

[0085] The flange 93 may be in a circular ring shape and is disposed on the periphery of the first annular body 91, and the flange 93 is located on the outside of the connecting section 533. The flange 93 is used to cooperate with the second connecting member 80, so that the first annular body 91 can cooperate with the second connecting member 80 through the flange 93 to achieve relative rotation of the two, thereby improving the rotation stability of the two while achieving the connection section 533 being rotatable relative to the water inlet pipe 10.

[0086] Please refer to Figures 3 to 6In some embodiments, the water inlet pipe 10 is arranged in an annular shape and includes a pipe body 13 and a mounting joint 15. The pipe body 13 is the main body of the water inlet pipe 10, and is used to transmit water to the connecting section 533 of the rotating shaft portion 53. The first annular body 91 is sleeved on the outside of the pipe body 13. The pipe body 13 is arranged in the mounting joint 15, that is, the mounting joint 15 is arranged on the outside of the pipe body 13, and the two cooperate to form a mounting ring groove 11, and the flange 93 is located in the mounting ring groove 11.

[0087] The mounting joint 15 is used to connect with the second connecting piece 80, so the mounting joint 15 serves as the connecting part of the water inlet pipe 10. Specifically, the second connecting piece 80 is arranged in a ring shape and is clamped with the mounting joint 15. The clamping form can ensure the connection stability between the second connecting piece 80 and the mounting joint 15, and facilitate the disassembly and assembly of the two, thereby improving the assembly efficiency.

[0088] Please refer to Figures 3 to 6 In some embodiments, the second connecting member 80 includes a second annular body 81 and an annular bearing portion 83 .

[0089] The second annular body 81 serves as the main structure of the second connecting member 80 and may be in a circular ring shape. Moreover, the second annular body 81 also serves as the connecting structure of the second connecting member 80 , and the second annular body 81 is snap-connected with the mounting joint 15 .

[0090] The annular bearing portion 83 is used to support the flange 93 of the first fastener. Specifically, the annular bearing portion 83 can be in a circular ring shape, and the annular bearing portion 83 is connected to the bottom of the second annular body 81, wherein the inner diameter of the annular bearing portion 83 is smaller than the inner diameter of the second annular body 81, and the annular bearing portion 83, the mounting joint 15 and the tube body 13 jointly define the installation space 60, and the flange 93 is confined in the installation space 60 and supported on the annular bearing portion 83.

[0091] With such arrangement, the annular bearing portion 83 can be used to support the flange 93, ensuring that the annular flange 93 has the annular bearing portion 83 to support it in the annular direction, and the wall surface of the installation space 50 can be used to limit the flange 93 to prevent the flange 93 from detaching, thereby further improving the stability of the cooperation between the first connecting member 90 and the second connecting member 80.

[0092] In order to reduce the wear degree of the first connecting member 90 and the second connecting member 80 when they rotate relative to each other, please refer to Figure 3 to Figure 4 In some embodiments, the spray device 100 further includes an anti-wear sheet 70. The anti-wear sheet 70 may be in a circular ring shape, and the anti-wear sheet 70 may be made of a plastic material such as nylon, so as to have advantages such as better wear resistance.

[0093] The anti-wear sheet 70 is sleeved on the outer periphery of the connecting section 533 and is disposed between the flange 93 and the annular bearing portion 83. In this way, the anti-wear sheet 70 can be sandwiched between the flange 93 and the annular bearing portion 83 to avoid excessive wear caused by direct contact between the flange 93 and the annular bearing portion 83 during the relative rotation process, which is conducive to extending the service life of the first connecting member 90 and the second connecting member 80.

[0094] In order to improve the convenience of the first annular body 91 and the connecting section 533, in some embodiments, see Figure 5 One of the outer peripheral surface of the first annular body 91 and the inner side surface of the connecting section 533 is provided with a first rotating buckle 911, and the other is provided with a first rotating groove 533a. The first rotating buckle 911 and the first rotating groove 533a are connected in a manner of relative rotation around the axial direction of the rotating shaft portion 53.

[0095] Thus, when actually connecting, only at least one of the first annular body 91 and the connecting segment 533 needs to be rotated to achieve relative rotation of the two around the axial direction of the rotating shaft 53, so that the two can be connected, which is very convenient to operate, and the connection is relatively firm, and the two are not easy to loosen. Of course, the present application is not limited to this, and in other embodiments, the first annular body 91 and the connecting segment 533 can also be connected in other forms such as elastic connection or lock connection.

[0096] Please continue reading Figure 5 Further, the first rotating buckle 911 includes a first buckle portion 9111 and a second buckle portion 9113. The first buckle portion 9111 and the second buckle portion 9113 can be a convex block integrally formed on the outer peripheral surface of the first annular body 91 or the inner side surface of the connecting section 533, and the first buckle portion 9111 extends along the circumferential direction of the first annular body 91, and the second buckle portion 9113 extends along the axial direction of the rotating shaft portion 53. The first buckle portion 9111 and the second buckle portion 9113 are connected to each other.

[0097] The first rotating slot 533a includes a first slot 533b, a first slot 533c and a second slot 533d which are connected in sequence. The first slot 533b allows the first snap part 9111 to snap into the first slot 533c, and the second snap part 9113 to snap into the second slot 533d. Specifically, the first snap part 9111 and the second snap part 9113 can slide into the first slot 533b along the axial direction of the shaft 53. After that, the first annular body 91 can rotate relative to the connecting section 533 around the axial direction of the shaft 53, so that the first snap part 9111 snaps into the first slot 533c to prevent the first annular body 91 from being separated from the connecting section 533 along the axial direction of the shaft 53, and the second snap part 9113 snaps into the second slot 533d to prevent the first annular body 91 from being separated from the connecting section 533 along its circumferential direction.

[0098] In this way, on the basis of realizing the rotational locking, it is possible to prevent the first locking component and the connecting section 533 from being separated in the axial direction of the rotating shaft portion 53, and also prevent the first locking component and the connecting section 533 from being separated along the circumferential direction of the rotating shaft portion 53, thereby improving the firmness of the locking between the first locking component and the connecting section 533.

[0099] In order to improve the convenience of the second annular body 81 and the mounting connector 15, please refer to Figure 6 In some embodiments, one of the outer peripheral surface of the mounting joint 15 and the inner surface of the second annular body 81 is provided with a second rotating buckle 151, and the other is provided with a second rotating groove 811. The second rotating buckle 151 and the second rotating groove 811 are connected in a manner of relative rotation around the axial direction of the rotating shaft portion 53.

[0100] Thus, when actually connecting, only at least one of the second annular body 81 and the mounting joint 15 needs to be rotated to achieve relative rotation of the two around the axial direction of the rotating shaft 53, so that the two can be connected, which is very convenient to operate, and the connection is relatively firm, and the two are not easy to loosen. Of course, the present application is not limited to this, and in other embodiments, the second annular body 81 and the mounting joint 15 can also be connected in other forms such as elastic connection or lock connection.

[0101] Please continue reading Figure 6Further, the second rotating buckle 151 includes a third buckle portion 1511 and a fourth buckle portion 1513. The third buckle portion 1511 and the fourth buckle portion 1513 can be a protrusion integrally formed on the outer peripheral surface of the mounting joint 15 or the inner side surface of the second annular body 81, and the third buckle portion 1511 extends along the circumferential direction of the second annular body 81, and the fourth buckle portion 1513 extends along the axial direction of the rotating shaft portion 53. The third buckle portion 1511 and the fourth buckle portion 1513 are connected to each other. The second rotating slot 811 includes a second slide slot 813, a third slot 815 and a fourth slot 817 that are connected in sequence. Among them, through the second slide groove 813, the third snap-in portion 1511 is snap-connected with the third snap-in portion 815, and the fourth snap-in portion 1513 is snap-connected with the fourth snap-in portion 817. Specifically, the third snap-in portion 1511 and the fourth snap-in portion 1513 can slide into the second slide groove 813 along the axial direction of the rotating shaft portion 53. After that, the second annular body 81 can rotate around the axial direction of the rotating shaft portion 53 relative to the mounting joint 15, so that the third snap-in portion 1511 is snap-connected into the third snap-in portion 815 to prevent the second annular body 81 from being separated from the mounting joint 15 along the axial direction of the rotating shaft portion 53, and the fourth snap-in portion 1513 is snap-connected into the fourth snap-in portion 817 to prevent the second annular body 81 from being separated from the mounting joint 15 along its circumferential direction.

[0102] In this way, on the basis of realizing the rotational clamping, not only can the second clamping member be prevented from being separated from the mounting joint 15 in the axial direction of the rotating shaft portion 53, but also the second clamping member can be prevented from being separated from the mounting joint 15 along the circumferential direction of the rotating shaft portion 53, thereby improving the firmness of the clamping between the second clamping member and the mounting joint 15.

[0103] It should be noted that, in the above two types of rotating snap connection, the spray device 100 of the present application can adopt any one of the forms, or can adopt both forms at the same time, which is not discussed in the embodiments of the present application.

[0104] Please continue reading Figures 7 to 10 In some embodiments, the spray chamber 31 includes a first spray chamber 311 and a second spray chamber 313, and the spray holes 33 include a first spray hole 331 connected to the first spray chamber 311 and a second spray hole 333 connected to the second spray chamber 313. The driving direction of the first spray hole 331 is opposite to that of the second spray hole 333. In this way, when water flows to the first spray chamber 311 or the second spray chamber 313, it can be sprayed outward along the corresponding first spray hole 331 and the second spray hole 333, and the rotation of the spray arm 30 is realized. For example, when water flows to the first spray chamber 311 and then sprays out from the first spray hole 331, the spray arm 30 can rotate forward under the driving force of the reverse action of the water. On the contrary, when water flows to the second spray chamber 313 and then sprays out from the second spray hole 333, the spray arm 30 can be reversed under the driving force of the reverse action of the water.

[0105] The water inlet valve 50 is a water diverter valve. The valve body 51 has at least one water inlet 511 and a first water outlet 512a and a second water outlet 512b. The first spray chamber 311 is connected to the first water outlet 512a, and the second spray chamber 313 is connected to the second water outlet 512b. The water inlet valve 50 also includes a moving body 55 (such as Figure 3 ), the movable body 55 is movably arranged inside the valve body 51, and the movable body 55 can be arranged in a spherical shape so that it can move more smoothly inside the valve body 51, and its diameter should be slightly larger than the diameter of the water outlet 512 so that the water outlet 512 can be blocked.

[0106] The movable body 55 is configured as follows: when water enters the water inlet 511, the movable body 55 is driven by the water flow to move inside the valve body 51, and under the action of the fluid, it can switchably block one of the two water outlets 512. In this way, the movable body 55 can switchably block one of the first water outlet 512a and the second water outlet 512b, so that the water diversion valve can control the water flow to one of the first spray chamber 311 and the second spray chamber 313, and further can realize the forward and reverse rotation of the spray arm 30 (that is, realize the clockwise rotation or counterclockwise rotation of the spray arm 30) to improve the washing effect of the spray device 100 on the tableware. In addition, the movable part can move only by the action of the water flow to control the flow direction of the water flow. This form does not require other electronic devices and is more stable and reliable.

[0107] See also Figure 3 In some embodiments, the water inlet 511 includes a first water inlet 511a and a second water inlet 511b, the first water inlet 511a and the second water inlet 511b are both arranged on the inner wall of the valve body 51, and the first water outlet 512a and the second water outlet 512b are both arranged on the top wall of the valve body 51.

[0108] In the gravity direction, the first water inlet 511a and the second water inlet 511b are both lower than the first water outlet 512a and the second water outlet 512b. In this way, by setting the first water inlet 511a and the second water inlet 511b, the water flow is disconnected and the accumulated water in the water diversion valve is discharged through the first water inlet 511a and the second water inlet 511b. Compared with only one water inlet 511, the water flow of each water inlet 511 is reduced at least two water inlets 511, which can improve the problem of excessive drainage flow at a single water inlet 511 causing the position of the moving body 55 to be uncontrollable.

[0109] Please refer to Figures 8 to 10Furthermore, the first water inlet 511a and the second water inlet 511b are centrally symmetrical about the axis of the rotating shaft 53. In this way, the balance of each part of the valve body 51 can be achieved when it is used, and the balancing step of the valve body 51 is omitted. It is also convenient for the main body section 531 to be connected with the first water inlet 511a and the second water inlet 511b, so that the shape of the rotating shaft 53 is more regular for easy design and manufacturing. Of course, the first water inlet 511a and the second water inlet 511b can also be asymmetrically arranged about the axis of the rotating shaft 53, and this embodiment does not limit this.

[0110] Please refer to Figures 8 to 10 Furthermore, the first water outlet 512a and the second water outlet 512b are centrally symmetrical about the axis of the rotating shaft 53. This is beneficial to the balance of various parts of the valve body 51 when it is used, and the balancing step of the valve body is omitted. Of course, the first water outlet 512a and the second water outlet 512b can also be asymmetrically arranged about the axis of the rotating shaft 53, and this embodiment does not limit this.

[0111] Please refer to Figures 8 to 10 , further, the first water inlet 511a and the second water inlet 511b are centrally symmetrical about the axis of the rotating shaft 53, so that the balance of various parts of the valve body 51 can be achieved when it is used, and the balancing step of the valve body 51 is omitted. It is also convenient for the main section 531 to be connected with the first water inlet 511a and the second water inlet 511b, so that the shape of the rotating shaft 53 is more regular for easy design and manufacturing. The first water outlet 512a and the second water outlet 512b are centrally symmetrical about the axis of the rotating shaft 53, so that it is beneficial to balance various parts of the valve body 51 when it is used, and the balancing step of the valve body is omitted. Of course, the first water inlet 511a and the second water inlet 511b can also be asymmetrically arranged about the axis of the rotating shaft 53, and the first water outlet 512a and the second water outlet 512b can also be asymmetrically arranged about the axis of the rotating shaft 53, and this embodiment does not limit this.

[0112] Please refer to Figures 8 to 9 In some embodiments, the valve body 51 further has a first low position 513 and a second low position 514, and the first water inlet 511a, the first low position 513, the first water outlet 512a, the second water inlet 511b, the second low position 514 and the second water outlet 512b are sequentially arranged along the circumference of the valve body 51;

[0113] The movable body 55 is configured such that when the movable body 55 is located at the first low position 513 and water flows into the first water inlet 511a and the second water inlet 511b, the movable body 55 is driven by the water flow and blocks the first water outlet 512a; when the movable body 55 is located at the second low position 514 and water flows into the first water inlet 511a and the second water inlet 511b, the movable body 55 is driven by the water flow and blocks the second water outlet 512b. In this way, the movable body 55 can selectively block the first water outlet 512a or the second water outlet 512b to change the rotation direction of the spray arm 30.

[0114] In the direction of gravity, the first water inlet 511a is lower than the first water outlet 512a, and the second water inlet 511b is lower than the second water outlet 512b. When the first water inlet 511a and the second water inlet 511b stop taking in water, the moving body 55 loses the effect of the fluid and falls back to the first low position 513 or the second low position 514. The first low position 513 and the second low position 514 can be the low positions in the valve body 51. When the first water inlet 511a and the second water inlet 511b stop taking in water, and the accumulated water in the valve body 51 is discharged through the first water inlet 511a and the second water inlet 511b, after the moving body 55 moves to the first low position 513 or the second low position 514, since the first low position 513 and the second low position 514 are relatively low, the moving body 55 here is not easy to be further driven by the effect of the fluid, so that it can be relatively stably maintained in the first low position 513 or the second low position 514.

[0115] In the embodiment of the present application, the moving body 55 is configured as follows: when the moving body 55 is located at the first low position 513 and water is flowing into the first water inlet 511a and the second water inlet 511b, the moving body 55 is driven by the water flow and blocks the first water outlet 512a; when the first water inlet 511a and the second water inlet 511b stop flowing, the moving body 55 loses the effect of the fluid and falls from the first water outlet 512a through the second water inlet 511b to the second low position 514. When the moving body 55 is located at the second low position 514 and water is flowing into the first water inlet 511a and the second water inlet 511b, the moving body 55 is driven by the water flow and blocks the second water outlet 512b; when the first water inlet 511a and the second water inlet 511b stop flowing, the moving body 55 loses the effect of the fluid and falls from the second water outlet 512b through the first water inlet 511a to the first low position 513.

[0116] The spray device 100 can be connected to a washing pump when in use, and whether the first water inlet 511a and the second water inlet 511b are filled with water or stopped can be controlled by starting or stopping the washing pump. Specifically, when the washing pump is started, water is filled into the first water inlet 511a and the second water inlet 511b, and when the washing pump is stopped, water is stopped from entering the first water inlet 511a and the second water inlet 511b.

[0117] The use process of the embodiment of the present application can be: if the washing pump is started, water enters the first water inlet 511a and the second water inlet 511b, and the moving body 55 moves from the first low position 513 to the first water outlet 512a under the action of the fluid and blocks the first water outlet 512a. At this time, the water in the valve body is discharged through the second water outlet 512b. If the washing pump is stopped, the first water inlet 511a and the second water inlet 511b stop entering, and the accumulated water in the valve body is discharged through the first water inlet 511a and the second water inlet 511b. The moving body 55 loses the action of the fluid and falls back to the second low position 514 from the first water outlet 512a through the second water inlet 511b under the action of gravity.

[0118] When the washing pump is started again, water enters the first water inlet 511a and the second water inlet 511b, and the moving body 55 moves from the second low position 514 to the second water outlet 512b under the action of the fluid and blocks the second water outlet 512b. At this time, the water in the valve body is discharged through the first water outlet 512a. If the washing pump stops, the first water inlet 511a and the second water inlet 511b stop entering, and the accumulated water in the valve body is discharged through the first water inlet 511a and the second water inlet 511b. The moving body 55 loses the action of the fluid and falls back to the first low position 513 from the second water outlet 512b through the first water inlet 511a under the action of gravity. By repeatedly starting and stopping the washing pump, the alternating water discharge from the first water outlet 512a and the second water outlet 512b can be achieved.

[0119] See also Fig. 9 In some embodiments, the inner bottom wall of the valve body 51 is provided with a first lower guide structure 515 and a second lower guide structure 516, and a first low position 513 and a second low position 514 are formed between the first lower guide structure 515 and the second lower guide structure 516. The first lower guide structure 515 is at least used to guide the moving body 55 to move to the second low position 514 when it falls back from the first water outlet 512a. Based on this, the moving path of the moving body 55 can be guided by the first lower guide structure 515, which can reduce the design requirements for the pipe shape inside the valve body 51. Since the first lower guide structure 515 occupies a smaller space than the inside of the valve body 51, the design requirements will be relatively reduced.

[0120] The second lower guide structure 516 is at least used to guide the moving body 55 to move to the first low position 513 when it falls back from the second water outlet 512b. Based on this, the movement path of the moving body 55 can be guided by the second lower guide structure 516, which can reduce the design requirements for the pipe shape inside the valve body 51. Since the second lower guide structure 516 occupies a smaller space than the inside of the valve body 51, the design requirements will be relatively reduced.

[0121] See also Fig.10 In some embodiments, the inner top wall of the valve body 51 is convexly provided with a first upper guide structure 517. Along the water flow direction of the valve body 51, the protruding height of the first upper guide structure 517 gradually decreases and is located between the first low position 513 and the first water outlet 512a. The first upper guide structure 517 is used to guide the moving body 55 to move to the first water outlet 512a under the action of the water flow. Based on this, the movement path of the moving body 55 can be guided by the first upper guide structure 517, which can reduce the design requirements for the pipe shape inside the valve body 51. Since the first upper guide structure 517 occupies a smaller space than the inside of the valve body 51, the design requirements will be relatively reduced.

[0122] See also Fig.10 In some embodiments, the inner top wall of the valve body 51 is convexly provided with a second upper guide structure 518. Along the water flow direction of the valve body 51, the protruding height of the second upper guide structure 518 gradually decreases and is located between the second low position 514 and the second water outlet 512b. The second upper guide structure 518 is used to guide the moving body 55 to move to the second water outlet 512b under the action of the water flow. Based on this, the movement path of the moving body 55 can be guided by the second upper guide structure 518, which can reduce the design requirements for the pipe shape inside the valve body 51. Since the second upper guide structure 518 occupies a smaller space than the inside of the valve body 51, the design requirements will be relatively reduced.

[0123] See also Fig.10 In some embodiments, the inner top wall of the valve body 51 is provided with a first upper guide structure 517, and the inner top wall of the valve body 51 is provided with a second upper guide structure 518. In this way, the movement path of the moving body 55 can be guided by the first upper guide structure 517 and the second upper guide structure 518, respectively, which greatly reduces the design requirements.

[0125] The spray arm 30 is located in the washing cavity, and the spray arm 30 serves as at least one of the middle spray arm and the top spray arm of the dishwasher. It is understandable that the dishwasher may include a top spray arm, a middle spray arm and a bottom spray arm, which are arranged in the washing cavity from top to bottom along the height direction of the dishwasher, so that water flow can be output in different areas of the washing cavity, thereby improving the cleaning effect of the dishwasher on the dishes.
