[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] Reference below Figure 1-Figure 5 A spray rod driving device 100 of a dishwasher according to an embodiment of the present invention is described.

[0037] like Figure 1-Figure 4 As shown, the spray rod driving device 100 of the dishwasher according to the embodiment of the present invention includes a housing 11, a driver 20 and a transmission mechanism.

[0038] The driver 20 and the transmission mechanism are arranged on the housing 11. The driver 20 has a driving shaft 21. The transmission mechanism includes an active transmission member 31 and a plurality of driven transmission members 32. For example, the number of the driven transmission members 32 can be two or more. The active transmission member 31 is connected to the driving shaft 21. The active transmission member 31 is transmission-connected to the plurality of driven transmission members 32. The plurality of driven transmission members 32 are respectively used for one-to-one connection with a plurality of spray bars (not shown) of the dishwasher.

[0039] The housing 11 defines a plurality of chambers 1102 arranged at intervals, a bearing 50 is provided in the chamber 1102, each driven transmission member 32 has a water pipe 321, the water pipe 321 is rotatably supported on the bearing 50, one end of the water pipe 321 has a water inlet 3211, the other end of the water pipe 321 has a water outlet 3212, the water inlet 3211 and the water outlet 3212 are exposed in the chamber 1102, and the water outlet 3212 can be connected to the spray rod of the dishwasher to supply water to the spray rod.

[0040] When the driver 20 is working, the driving shaft 21 can drive the active transmission member 31 to rotate. Since the active transmission member 31 is connected to the multiple driven transmission members 32, the active transmission member 31 can drive the multiple driven transmission members 32 to rotate respectively, thereby driving the multiple spray rods of the dishwasher to rotate and achieve a spray washing effect.

[0041] According to the spray rod driving device 100 of the dishwasher according to the embodiment of the present invention, by providing a transmission mechanism including an active transmission member 31 and a plurality of driven transmission members 32, a driver 20 can be used to simultaneously drive a plurality of spray rods to rotate, thereby increasing the spraying range of the dishwasher, further improving the cleaning effect, and facilitating the modular design of the spray rod assembly of the dishwasher, with a simple structure and small space occupation.

[0042] In addition, there is no need to set up a water chamber in the outer shell 11. Water flows directly from the water inlet 3211 through the water pipe 321, and then flows to the spray rod from the water outlet 3212. The water will not enter the chamber 1102, so the water will not contact the bearing 50, reducing the possibility of water clogging the bearing 50. In addition, since the water inlet 3211 is formed at one end of the water pipe 321 and the water outlet 3212 is formed at the other end, the outer shell 11 does not need to form a closed structure, which simplifies the structure of the outer shell 11 and makes installation more convenient.

[0043] like Figure 5 As shown, according to some embodiments of the present invention, the spray rod driving device 100 of the dishwasher further includes a water distribution pipe 800 , and the water distribution pipe 800 has a plurality of water distribution ports 803 , and the plurality of water distribution ports 803 are connected to the plurality of water inlets 3211 in a one-to-one correspondence.

[0044] Thus, by providing the water distribution pipe 800, water can be passed into the water pipe 321 through the water distribution pipe 800, so that the water is transported to the spray rod to achieve a spraying effect. In addition, by forming a water inlet 3211 at one end of the water pipe 321, the water distribution pipe 800 structure in the related art can be directly used, or only a minor modification of the water distribution pipe 800 structure is required to achieve the water distribution function.

[0045] In some embodiments, a fixed cover 12 is provided at the opening of the chamber 1102, at least a portion of the water pipe 321 extends into the chamber 1102, and the water pipe 321 passes through the fixed cover 12. The fixed cover 12 and the housing 11 can be connected by a snap-fit ​​structure, for example, the fixed cover 12 can be screwed to the housing 11 by rotating the fixed cover 12.

[0046] Specifically, Figure 1 and Figure 3 As shown, the top and bottom of the chamber 1102 have openings respectively, the water pipe 321 extends into the chamber 1102 from the bottom opening of the chamber 1102, and extends out from the top opening of the chamber 1102, a fixed cover 12 is sleeved on the top opening of the chamber 1102, and the middle part of the fixed cover 12 has a through opening, and one end of the water pipe 321 extending into the chamber 1102 extends into the through opening.

[0047] like Figure 3 As shown, in some examples, a first seal 14 is provided between the fixed cover 12 and the water pipe 321, that is, the first seal 14 is clamped between the inner surface of the fixed cover 12 and the outer surface of the water pipe 321, thereby ensuring the sealing between the fixed cover 12 and the water pipe 321 to prevent water leakage.

[0048] like Figure 5 As shown, in some examples, the water distribution pipe 800 has a main water pipe 801 and multiple water distribution branch pipes 802, one end of the multiple water distribution branch pipes 802 is connected to the main water pipe 801, and the other end of the multiple water distribution branch pipes 802 defines a water distribution port 803, and the other end of the multiple water distribution branch pipes 802 is sleeved on the outside of the fixed cover 12, so that the water distribution pipe 800 can be used to simultaneously transport water to multiple water pipes 321, thereby achieving the effect of multiple spray rods spraying water at the same time, thereby increasing the spraying range of the dishwasher and improving the cleaning effect.

[0049] like Figure 3 As shown, in some specific examples, a second sealing member 15 is provided between the fixed cover 12 and the water distribution branch pipe 802. That is, the second sealing member 15 is sandwiched between the outer surface of the fixed cover 12 and the inner surface of the water distribution branch pipe 802, thereby ensuring the sealing between the fixed cover 12 and the water distribution branch pipe 802 to prevent water leakage.

[0050] like Figure 1 and Figure 3 As shown, in some examples, a bearing 50 is provided in the chamber 1102, and the water pipe 321 is rotatably supported on the bearing 50. By providing the bearing 50, the driven transmission member 32 can be positioned and installed, ensuring that the driven transmission member 32 can be connected to the driving transmission member 31, thereby driving the spray rod.

[0051] Specifically, the water pipe 321 can be formed into a straight pipe extending in the up-down direction, the active transmission member 31 is formed into a driving gear, the driven transmission member 32 includes a driven gear meshing with the driving gear, and the water pipe 321 is connected to the driven transmission member 32 to ensure that the rotation axis of the water pipe 321 coincides with the rotation axis of the driven transmission member 32. The driven transmission member 32 can be connected to one end of the water pipe 321 or to the middle of the water pipe 321.

[0052] Of course, the water pipe 321 may not be a completely straight pipe, that is, a part of the water pipe 321 is formed into a straight pipe and the other part is formed into other shapes, so that the axis of the other part of the water pipe 321 does not coincide with the rotation axis of the water pipe 321. For example, the axis of the other part of the water pipe 321 is set to be parallel to the rotation axis of the water pipe 321 and separated by a preset distance, thereby increasing the spray range on the basis of ensuring that the water pipe 321 and the spray rod do not interfere with other components during rotation.

[0053] In order to ensure that the driving gear and the plurality of driven gears can mesh normally, the driving gear and the plurality of driven gears need to be arranged in the same plane. The sizes of the plurality of driven gears and the driving gear may be the same or different.

[0054] like Figure 3 As shown, in order to ensure the rotation stability and reliability of the driven transmission member 32, in some embodiments, at least two bearings 50 are provided in the chamber 1102, so that the at least two bearings 50 can more stably support the water pipe 321. Among them, a separator 60 is provided between two adjacent bearings 50, and the separator 60 is fixedly matched with the two adjacent bearings 50, so that the at least two bearings 50 are arranged separately, and the support reliability of the bearing 50 for the driven transmission member 32 is further improved.

[0055] In some examples, one of the bearing 50 and the separator 60 has a limiting protrusion 51, and the other of the bearing 50 and the separator 60 has a limiting hole 61, and the limiting protrusion 51 cooperates with the limiting hole 61 to ensure the fixed cooperation between the bearing 50 and the separator 60. Specifically, as Figure 1 As shown, in this embodiment, the outer wall of the bearing 50 is provided with a limiting protrusion 51, and the separator 60 has a limiting hole 61 with an opening on one side, so as to facilitate the insertion of the limiting protrusion 51 into the limiting hole 61 to achieve fixed fit between the bearing 50 and the separator 60.

[0056] like Figure 1 and Figure 3As shown, a limit member 70 is provided at one end of the water pipe 321 extending into the chamber 1102, that is, a limit member 70 is provided at one end of the water pipe 321 away from the active transmission member 31. The limit member 70 is located between the bearing 50 and the first sealing member 14, and can limit the water pipe 321 to prevent the water pipe 321 from escaping from the chamber 1102.

[0057] Specifically, Figure 1 As shown, the limiting member 70 forms an annular structure, and the limiting member 70 has a plurality of arc ribs arranged at intervals along its circumference, and there is a gap between two adjacent arc ribs. A limiting protrusion is provided on the inner side of at least two of the spaced-apart arc ribs, and the limiting protrusion is inserted into the limiting hole on the water pipe 321.

[0058] like Figure 1-Figure 3 As shown, according to some embodiments of the present invention, the spray rod driving device 100 of the dishwasher further includes a connecting member 40, and the driving shaft 21 is connected to the active transmission member 31 through the connecting member 40. By providing the connecting member 40, the rotational motion and power of the driving shaft 21 can be transmitted to the active transmission member 31, thereby realizing the driving of the spray rod.

[0059] In some embodiments, the housing 11 defines an installation cavity 1101, and the driver 20 is disposed in the installation cavity 1101, that is, the housing 11 protects the driver 20, and the active transmission member 31 is disposed outside the installation cavity 1101, thereby facilitating the transmission connection between the active transmission member 31 and the driven transmission member 32, thereby facilitating the output of movement and power.

[0060] The connecting member 40 includes a connecting shaft 41 , one end of which extends into the installation cavity 1101 , and one end of the connecting shaft 41 cooperates with the driving shaft 21 , and the other end of the connecting shaft 41 is connected to the active transmission member 31 .

[0061] It should be noted that the matching relationship between the connecting shaft 41 and the driving shaft 21 can be direct matching or indirect matching. Similarly, the connecting shaft 41 and the active transmission member 31 can be directly connected or indirectly connected through other components. By providing the connecting shaft 41, the rotational motion and power of the driving shaft 21 can be transmitted to the active transmission member 31, and the connection is reliable.

[0062] In order to ensure the sealing between the connecting shaft 41 and the outer shell 11, in some examples, the inner side of the outer shell 11 has a first mounting groove extending along the circumference of the connecting shaft 41, and a third seal 16 is provided in the first mounting groove. The third seal 16 is tightly attached to the inner wall of the first mounting groove and the outer wall of the connecting shaft 41, thereby ensuring the sealing between the connecting shaft 41 and the outer shell 11.

[0063] In some examples, the connecting shaft 41 may form a camshaft, and a convex portion of the camshaft in the circumferential direction may cooperate with a water control switch of the dishwasher, so that when the camshaft rotates, the opening and closing of the water control switch is controlled.

[0064] like Figure 1 and Figure 3 As shown, in some examples, one end of the connecting shaft 41 has a first connecting hole 410, and the driving shaft 21 is inserted into the first connecting hole 410, so that the connection is reliable and the assembly and disassembly are convenient. Among them, at least a part of the cross-sectional shape of the driving shaft 21 is the same as the cross-sectional shape of the first connecting hole 410.

[0065] In order to achieve synchronous rotation of the driving shaft 21 and the connecting shaft 41, the first connecting hole 410 can be set as a special-shaped hole. For example, the first connecting hole 410 can be set as a D-shaped hole. Correspondingly, at least a portion of the cross-sectional shape of the driving shaft 21 forms a D-shape. Of course, the first connecting hole 410 can also be set to other shapes such as an elliptical hole.

[0066] like Figure 1 and Figure 3 As shown, in some examples, the connecting member 40 further includes a card 42 , and the other end of the connecting shaft 41 is connected to the active transmission member 31 through the card 42 , thereby ensuring the connection reliability between the connecting shaft 41 and the active transmission member 31 .

[0067] In some specific examples, the card 42 has a second connection hole 421, and the other end of the connection shaft 41 is inserted into the second connection hole 421, which is reliable and easy to assemble and disassemble. The cross-sectional shape of the other end of the connection shaft 41 is the same as the cross-sectional shape of the second connection hole 421.

[0068] In order to achieve synchronous rotation of the card 42 and the connecting shaft 41, the second connecting hole 421 can be set as a special-shaped hole. For example, the second connecting hole 421 can be set as a D-shaped hole. Correspondingly, the cross-sectional shape of the other end of the connecting shaft 41 forms a D shape. Of course, the second connecting hole 421 can also be set to other shapes such as an elliptical hole.

[0069] It should be noted that the connection between the drive shaft 21 and the connecting shaft 41 and the connection between the card 42 and the connecting shaft 41 in the above embodiment is not limited to plug-in connection, but can also be threaded or connected by additionally providing connecting components.

[0070] like Figure 1 and Figure 3As shown, in a further example, the connecting shaft 41 includes a shaft body 411 and a fixing buckle 412, the shaft body 411 has a mounting hole 4110, one end of the fixing buckle 412 is connected to the inner wall of the mounting hole 4110, and the other end of the fixing buckle 412 forms a free end, that is, the fixing buckle 412 can be elastically deformed under the action of external force, and when the external force is removed, the fixing buckle 412 can also return to its original state.

[0071] Specifically, when the connecting shaft 41 is in cooperation with the second connecting hole 421, the fixing buckle 412 is accommodated in the mounting hole 4110, and the fixing buckle 412 abuts against the inner wall surface of the second connecting hole 421, thereby locking the card 42 on the connecting shaft 41, achieving the connection reliability between the connecting shaft 41 and the active transmission member 31, and allowing the connecting shaft 41 and the active transmission member 31 to rotate synchronously.

[0072] like Figure 4 As shown, in order to prevent the card 42 from falling off the connecting shaft 41, in the present embodiment, a buckle is provided on the outward side of one end of the fixing buckle 412, and in the process of the connecting shaft 41 passing through the second connecting hole 421, the free end of the fixing buckle 412 is squeezed and approaches the side of the shaft body 411, so that the connecting shaft 41 can smoothly pass through the second connecting hole 421; when the connecting shaft 41 and the second connecting hole 421 are matched, at least a part of the connecting shaft 41 extends out of the second connecting hole 421, and the fixing buckle 412 returns to its original state, so that the buckle of the fixing buckle 412 extends out of the second connecting hole 421 and stops at the outer surface of the card 42, thereby achieving an anti-falling effect.

[0073] like Figure 3 As shown, in a further example, the active transmission member 31 has a third connecting hole 311, and the side of the card 42 facing the active transmission member 31 has a convex ring 422, which extends circumferentially along the second connecting hole 421, and the convex ring 422 is inserted into the third connecting hole 311, thereby ensuring the connection reliability between the card 42 and the active transmission member 31.

[0074] In some examples, the active transmission member 31 further has a plurality of matching holes 312, and the card 42 has a plurality of convex ribs 423, and the plurality of convex ribs 423 are plugged into the plurality of matching holes 312 one by one, further ensuring the connection reliability between the card 42 and the active transmission member 31. The number of the matching holes 312 here can be two, or more than two.

[0075] In the example where the active transmission member 31 has both a third connecting hole 311 and a plurality of matching holes 312, the third connecting hole 311 is disposed in the middle of the active transmission member 31, so that the center of the third connecting hole 311 coincides with the rotation center of the active transmission member 31, thereby ensuring that the active transmission member 31 can rotate around its center, and the plurality of matching holes 312 are spaced apart in the circumferential direction of the third connecting hole 311, thereby further positioning the card 42 and achieving an anti-rotation effect.

[0076] like Figure 1-Figure 4 As shown, according to some other embodiments of the present invention, the housing 11 includes a main shell 111 and a plurality of water joints 112, the plurality of water joints 112 are arranged at intervals on the outer periphery of the main shell 111, each water joint 112 is connected to the side wall of the main shell 111 through a connecting plate 113, the main shell 111 defines an installation cavity 1101, and each water joint 112 defines a chamber 1102.

[0077] Among them, a driver 20 is provided in the installation cavity 1101, the active transmission member 31 is provided on the outside of the main shell 111 and is located at one end of the main shell 111, at least two bearings 50 are provided in the chamber 1102, and multiple driven transmission members 32 are respectively matched with multiple water joints 112 in a one-to-one correspondence. One end of the water pipe 321 of each driven transmission member 32 extends into the corresponding chamber 1102 and matches with the corresponding at least two bearings 50.

[0078] In some specific embodiments, the main housing 111 is formed into a column extending in the up-down direction, and the plurality of water-passing joints 112 are respectively formed into a column extending in the up-down direction, and the side wall of each water-passing joint 112 is connected to the side wall of the main housing 111 through at least two connecting plates 113 arranged at intervals up and down, thereby improving the connection reliability between the water-passing joint 112 and the main housing 111. Among them, the plurality of water-passing joints 112 can be arranged symmetrically with respect to the main housing 111, and the cross-sectional size of the water-passing joint 112 is smaller than the cross-sectional size of the main housing 111.

[0079] In order to facilitate the installation of the spray boom drive device 100, the spray boom drive device 100 also includes a mounting plate 13, which is connected to the main shell 111. For example, the mounting plate 13 can be connected to one end of the main shell 111 through multiple fasteners. Of course, the mounting plate 13 and the main shell 111 can also be connected by a snap-on manner, so that the mounting plate 13 and the main shell 111 are easy to install and disassemble and the connection is reliable.

[0080] In some embodiments, a second mounting groove is provided on one side of the main shell 111 facing the mounting plate 13. The second mounting groove extends along the circumference of the main shell 111. A fourth seal 17 is provided in the second mounting groove. The fourth seal 17 is tightly attached between the bottom wall of the second mounting groove and the mounting plate 13, thereby ensuring the sealing between the main shell 111 and the mounting plate 13.

[0081] The spray rod assembly of the dishwasher according to the embodiment of the present invention comprises the spray rod driving device 100 of the dishwasher according to the above embodiment and a plurality of spray rods (not shown), one end of each of the plurality of spray rods being connected to a plurality of driven transmission members 32 in a one-to-one correspondence. The driver 20 can drive the plurality of spray rods to rotate synchronously through the transmission mechanism, for example, the rotation axis of each spray rod can coincide with the rotation axis of the corresponding driven transmission member 32.
