[0036] Please refer to Figures 1 to 10 As shown in, a spray arm assembly 100 provided by an embodiment of the present utility model is used for a washing appliance. The spray arm assembly 100 includes a connecting member 12, an anti-collision assembly 14, a first spray arm 16, and a second spray arm 18. The first spray arm 16 and the second spray arm are rotatably connected to the connecting member 12. The anti-collision assembly 14 connects the first spray arm 16 and the second spray arm 18. The anti-collision assembly 14 is configured to synchronously rotate the first spray arm 16 and the second spray arm 18 and prevent the first spray arm 16 and the second spray arm 18 from colliding during rotation.

[0037] The above spray arm assembly 100 includes the first spray arm 16 and the second spray arm 18. Thus, when the spray arm assembly 100 is working, the cleaning area of the spray arm assembly 100 can be increased. At the same time, the anti-collision assembly 14 can also prevent the first spray arm 16 and the second spray arm 18 from colliding during rotation, avoiding the situation where the first spray arm 16 and the second spray arm 18 are damaged due to mutual collision.

[0038] Specifically, the washing appliance includes, but is not limited to, appliances such as dishwashers. The washing appliance includes a cavity, and a washing chamber is provided inside the cavity. The spray arm assembly 100 can be installed in the washing chamber.

[0039] A main flow channel 20 is provided inside the connecting member 12. A first sub-flow channel 22 is provided inside the first spray arm 16. A second sub-flow channel 24 is provided inside the second spray arm 18. Both the first sub-flow channel 22 and the second sub-flow channel 24 communicate with the main flow channel 20. A first spray hole 26 is provided on the first spray arm 16. A second spray hole 28 is provided on the second spray arm 18. The first spray hole 26 communicates with the first sub-flow channel 22. The second spray hole 28 communicates with the second sub-flow channel 24.

[0040] When the spray arm assembly 100 is working, water flow is introduced into the connecting member 12. The water flow passes through the main flow channel 20 and flows into the first sub-flow channel 22 and the second sub-flow channel 24. The water flow in the first sub-flow channel 22 is ejected outward from the first spray hole 26. The water flow in the second sub-flow channel 24 is ejected outward from the second spray hole 28 to clean the tableware in the cavity. The tableware includes, but is not limited to, bowls, plates, dishes, forks, knives, chopsticks, cups, spoons, bottles, etc.

[0041] The first spray arm 16 and the second spray arm 18 can rotate driven by the inertia of the flowing water. When one of the first spray arm 16 and the second spray arm 18 rotates, the other can be synchronously rotated through the anti-collision component 14, so that the first spray arm 16 and the second spray arm 18 can spray water into the cavity during the rotation process.

[0042] Optionally, in one embodiment, during the rotation process of the first spray arm 16 and the second spray arm 18, the rotation directions of the two are the same, so that the dirt remaining on the tableware can be repeatedly washed by the water flow, improving the cleaning effect to a certain extent. Figure 9 In [a specific situation], the first spray arm 16 and the second spray arm 18 rotate synchronously in the clockwise direction.

[0043] Optionally, please refer to Figure 10 , in one embodiment, during the rotation process of the first spray arm 16 and the second spray arm 18, the rotation directions of the two are opposite, so that the dirt remaining on the tableware can be repeatedly washed by the water flow in different directions, improving the cleaning effect to a certain extent.

[0044] When the first spray arm 16 and the second spray arm 18 rotate, the anti-collision component 14 can prevent the first spray arm 16 and the second spray arm 18 from colliding with each other, avoiding damage to the first spray arm 16 and the second spray arm 18.

[0045] In some embodiments, a part of the cleaning area formed by the rotation of the first spray arm 16 overlaps with a part of the cleaning area formed by the rotation of the second spray arm 18.

[0046] Thus, the space occupied by the spray arm assembly 100 can be reduced while increasing the cleaning area of the spray arm assembly 100.

[0047] Specifically, please refer to Figure 9 and Figure 10 , the cleaning area formed by the rotation of the first spray arm 16 is the first area C1, the cleaning area formed by the rotation of the second spray arm 18 is the second area C2, a part of the first area C1 overlaps with a part of the second area C2, forming an overlapping area. Thus, the first spray arm 16 and the second spray arm 18 are relatively close to each other, and the space occupied by the spray arm assembly 100 can be reduced. The size of the overlapping area C3 can be configured according to factors such as the internal space of the cavity, and the present utility model does not make specific limitations.

[0048] In Figure 9 , when the spray arm assembly 100 works, the first spray arm 16 rotates in the clockwise direction, and the second spray arm 18 rotates in the clockwise direction, and can rotate from Figure 9 state A to state E. In Figure 9In it, the arrow on the spray arm is used to distinguish one half of the spray arm from the other half, facilitating the identification of the rotation of the spray arm.

[0049] It can be understood that in other embodiments, the first region C1 and the second region C2 may not overlap either. In other embodiments, when the first spray arm 16 and the second spray arm 18 rotate, they may also rotate in the counterclockwise direction.

[0050] In certain embodiments, please combine Figure 6 , the bottom of the first spray arm 16 is flush with the bottom of the second spray arm 18.

[0051] Thus, the space occupied by the spray arm assembly 100 in the height direction can be reduced.

[0052] Specifically, in Figure 6 , the first spray arm 16 and the second spray arm 18 are connected to the bottom of the connecting member 12. The bottom of the first spray arm 16 is flush with the bottom of the second spray arm 18. In the height direction, the space occupied by the first spray arm 16 and the second spray arm 18 downward in the cavity can be reduced, and to a certain extent, it can be avoided that the first spray arm 16 and the second spray arm 18 touch the tableware below during operation.

[0053] In certain embodiments, the upper surface of the first spray arm 16 is provided with first spray holes 26, and the upper surface of the second spray arm 18 is provided with second spray holes 28.

[0054] Thus, the spray arm assembly 100 can wash the tableware upward.

[0055] Specifically, in order to reduce the water remaining on the tableware, the tableware is usually placed upside down or vertically in the bowl basket. The spray arm assembly 100 of the embodiment of the present utility model can be used as the middle spray arm assembly 100 and the lower spray arm assembly 100. The upper surface of the first spray arm 16 is provided with first spray holes 26, and the upper surface of the second spray arm 18 is provided with second spray holes 28, so that when the spray arm assembly 100 operates, it sprays water upward, and the sprayed water flow can directly spray onto the surface of the dirt remaining on the tableware, thereby effectively cleaning the tableware.

[0056] Optionally, the bottom surface of the first spray arm 16 and the bottom surface of the second spray arm 18 may also be provided with spray holes. Optionally, the number of the first spray holes 26 is multiple, and the multiple first spray holes 26 are arranged along the length direction of the first spray arm 16. The number of the second spray holes 28 is multiple, and the multiple second spray holes 28 are arranged along the length direction of the second spray arm 18.

[0057] Optionally, when the spray arm assembly 100 is applied to the upper spray arm assembly 100, the bottom surface of the first spray arm 16 and the bottom surface of the second spray arm 18 may be provided with spray holes.

[0058] In some embodiments, the anti-collision assembly 14 includes two gears 30 and a transmission belt 32. One of the gears 30 is fixedly connected to the first spray arm 16, and the other gear 30 is fixedly connected to the second spray arm 18. The transmission belt 32 connects the two gears 30 such that when one of the first spray arm 16 and the second spray arm 18 rotates, the other is driven to rotate synchronously through the transmission belt 32.

[0059] Thus, the structure of the anti-collision assembly 14 is simple and the cost is low.

[0060] Specifically, in one embodiment, the structures of the two gears 30 may be the same. Please refer to Figure 7 , a hollow first connecting column 34 and a hollow second connecting column 36 are provided on the connecting member 12, a hollow third connecting column 38 is provided on the first spray arm 16, and a hollow fourth connecting column 40 is provided on the second spray arm 18. A part of the first connecting column 34 penetrates into the third connecting column 38, and the first connecting column 34 is rotatably connected to the third connecting column 38. A part of the second connecting column 36 penetrates into the fourth connecting column 40, and the second connecting column 36 is rotatably connected to the fourth connecting column 40.

[0061] One gear 30 is sleeved on the outer peripheral surface of the third connecting column 38, and the other gear 30 is sleeved on the outer peripheral surface of the fourth connecting column 40. The inner peripheral surface of the transmission belt 32 meshes with the outer peripheral surfaces of the two gears 30 respectively.

[0062] Please refer to Figure 6 , the first spray arm 16 and the second spray arm 18 are substantially in the same horizontal plane, and a part of the cleaning area formed by the rotation of the first spray arm 16 overlaps with a part of the cleaning area formed by the rotation of the second spray arm 18. Under the flow inertia of the water flow, when the first spray arm 16 and the second spray arm 18 rotate, through the two gears 30 and the transmission belt 32, the first spray arm 16 and the second spray arm 18 can rotate synchronously, thereby avoiding collision during the rotation process. In one embodiment, please refer to Figure 9 , the initial states of the first spray arm 16 and the second spray arm 18 are as shown in Figure 9 State A. During the operation of the spray arm assembly 100, the rotation process of the first spray arm 16 and the second spray arm 18 is from State A to State E. The two spray arms rotate in the clockwise direction, and the anti-collision assembly 14 prevents the two spray arms from colliding.

[0063] To prevent the two spray arms from colliding during rotation, in mechanical design software, the structures of the spray arms, gear 30, and transmission belt 32 can be designed based on factors such as the mutual relationship between the first spray arm 16 and the second spray arm 18 during initial installation, the distance between the rotation centers, and the size of the overlapping area C3, so that the first spray arm 16 and the second spray arm 18 do not collide during rotation. Then, the first spray arm 16, the second spray arm 18, and the anti-collision component 14 are installed according to the determined mutual relationship.

[0064] In Figure 9 In the illustrated embodiment, the angle of the overlapping area C3 is A1. In state A, when the first spray arm 16 rotates clockwise from the right edge into the overlapping area C3, the second spray arm 18 is entirely outside the overlapping area C3, and the angle between the left side and the overlapping area C3 is A2, where A2 > A1. Thus, when the first spray arm 16 rotates clockwise from the left edge and leaves the overlapping area C3, the second spray arm 18 has not yet rotated clockwise from the left edge and entered the overlapping area C3 (from state A to state B). Therefore, during rotation, the first spray arm 16 and the second spray arm 18 do not collide.

[0065] Similarly, when the second spray arm 18 rotates clockwise from the left edge into the overlapping area C3 and rotates clockwise from the right edge and leaves the overlapping area C3, the first spray arm 16 has not yet rotated clockwise from the right edge and entered the overlapping area C3 (from state C to state D). When the first spray arm 16 rotates clockwise from the right edge and enters the overlapping area C3, the second spray arm 18 has already left the overlapping area C3 for some time (state E). Therefore, during rotation, the first spray arm 16 and the second spray arm 18 do not collide.

[0066] It can be understood that in other embodiments, the first spray arm 16 and the second spray arm 18 can rotate counterclockwise. In other embodiments, by changing the structure of the gear 30 and / or increasing the number of gears 30, the directions of synchronous rotation of the first spray arm 16 and the second spray arm 18 are opposite. Please refer to Figure 10 That is, one spray arm rotates clockwise and the other spray arm rotates counterclockwise.

[0067] In other embodiments, the first spray arm 16 and the second spray arm 18 can be in different horizontal planes. Even if a part of the first area C1 overlaps with a part of the second area C2, the first spray arm 16 and the second spray arm 18 do not collide during rotation.

[0068] In some embodiments, the spray arm assembly 100 includes a protective cover 42. The protective cover 42 is connected to the connecting member 12, and the transmission belt 32 and the gear 30 are located inside the protective cover 42.

[0069] Thus, to a certain extent, the situation where the anti-collision component 14 is stuck by sundries and causes the spray arm to jam can be avoided.

[0070] Specifically, when the spray arm assembly 100 is working, the sundries remaining on the tableware can be washed off. The washed-off sundries may fall into the meshing part of the transmission belt 32 and the gear 30, resulting in the transmission belt 32 and the gear 30 being stuck and the spray arm being unable to rotate.

[0071] The protective cover 42 can be fixedly connected or detachably connected to the connecting piece 12. The transmission belt 32 and the gear 30 are located inside the protective cover 42, which can, to a certain extent, avoid the situation where the anti-collision component 14 is stuck by sundries and causes the spray arm to jam, ensuring that the spray arm assembly 100 can work properly.

[0072] In some embodiments, the spray arm assembly 100 includes a mounting member 44. The mounting member 44 is connected to one end of the connecting piece 12 along the length direction, and the second spray arm 18 is connected to the other end of the connecting piece 12 along the length direction. The spray arm assembly 100 is configured to be detachably mounted in the cavity of the washing appliance through the mounting member 44.

[0073] Thus, the maintenance of the spray arm assembly 100 can be facilitated.

[0074] Specifically, when in use, the spray arm assembly 100 can be mounted in the cavity of the washing appliance. The spray arm assembly 100 is detachably mounted in the cavity of the washing appliance through the mounting member 44. When the spray arm assembly 100 needs to be maintained, the spray arm assembly 100 can be detached from the cavity without damaging the spray arm assembly 100.

[0075] Optionally, a joint 46 is provided on the mounting member 44. The joint 46 can be connected to the water pipe in the cavity, so that water can flow from the water pipe through the joint 46 into the main flow channel 20.

[0076] The second spray arm 18 is connected to the other end of the connecting piece 12 along the length direction, which can expand the cleaning area of the spray arm assembly 100 as much as possible.

[0077] In some embodiments, the mounting member 44 includes a mounting portion 48 and a connecting portion 50. The mounting portion 48 is connected to the connecting piece 12. The connecting portion 50 is provided on the mounting portion 48. The connecting portion 50 includes a first clamping block 52 and / or a first groove 54. The first clamping block 52 is configured to be connected in cooperation with the second groove on the cavity, and the first groove 54 is configured to be connected in cooperation with the second clamping block on the cavity.

[0078] Thus, the cooperation mode of the clamping block and the groove is simple and easy to implement.

[0079] Specifically, in one embodiment, please refer to Figure 1The connecting portion 50 includes a plurality of first clamping blocks 52, which are arranged on the mounting portion 48 along the circumferential direction of the mounting portion 48. The shape of the first clamping blocks 52 makes it more convenient and quick to install the spray arm assembly 100 than to remove the spray arm assembly 100. The first clamping blocks 52 can be clamped in the second groove on the cavity, so that the spray arm assembly 100 can be installed on the cavity.

[0080] In one embodiment, please combine Figure 2 The connecting portion 50 includes a plurality of first blocks 52 and a plurality of first grooves 54. The plurality of first blocks 52 are arranged on the mounting portion 48 along the circumferential direction of the mounting portion 48. The plurality of first grooves 54 are arranged on the mounting portion 48 along the circumferential direction of the mounting portion 48. The first blocks 52 and the first grooves 54 are alternately arranged to provide a more stable mounting effect. The shape of the first block 52 makes it more convenient and quick to install the spray arm assembly 100 than to remove the spray arm assembly 100. The first block 52 can be stuck in the second groove on the cavity, and the second block on the cavity can be stuck in the first groove 54, so that the spray arm assembly 100 can be installed on the cavity.

[0081] In some embodiments, a receiving groove 56 is provided on the mounting member 44, and the spray arm assembly 100 includes a limiting member 58, which is connected to the mounting member 44, and the receiving groove 56 is configured to accommodate a connecting strip 57 of the bowl basket of the washing appliance, and the limiting member 58 is configured to limit the connecting strip 57 in the receiving groove 56.

[0082] Thereby, the spray arm assembly 100 can be connected to the bowl basket.

[0083] Specifically, in Figure 6 In the embodiment, the receiving groove 56 is provided on the mounting portion 48, the connecting strip 57 can be a metal strip, and the bowl baskets include but are not limited to the lower bowl basket, the middle bowl basket and the upper bowl basket. The limiting member 58 can limit the connecting strip 57 in the receiving groove 56 to prevent the spray arm assembly 100 from unexpectedly moving during the operation of the washing appliance, thereby reducing the cleaning effect.

[0084] exist Figure 6 In the embodiment, the connecting strip 57 is cylindrical and the receiving groove 56 is substantially cylindrical. The receiving groove 56 has an opening 60. After the spray arm assembly 100 is installed on the cavity, the opening 60 faces the door of the washing appliance ( Figure 6 When the bowl basket is pushed into the cavity (in the forward direction), the connecting strip 57 can squeeze the limiting member 58 from the opening 60 of the receiving groove 56 and enter the receiving groove 56, and the limiting member 58 is squeezed to elastically deform upward. When the connecting strip 57 is installed in place, the limiting member 58 can recover from the deformation so that the connecting strip 57 can be limited on the opening 60 to prevent the spray arm assembly 100 from being separated from the bowl basket.

[0085] When the bowl basket (in the forward direction) is pulled out of the cavity, the connecting bar 57 can squeeze the limiting member 58 in the direction close to the door body (forward direction), causing the limiting member 58 to undergo upward elastic deformation, so that the connecting bar 57 can be disengaged from the receiving groove 56. After the connecting bar 57 is completely disengaged from the receiving groove 56, the bowl basket can be smoothly pulled out, and the limiting member 58 can recover from the deformation.

[0086] Optionally, a protective member 62 is further provided on the mounting member 44. The protective member 62 and the receiving groove 56 are respectively located on opposite sides of the limiting member 58. The protective member 62 can limit the maximum deformation amount of the limiting member 58 to avoid the situation that the limiting member 58 breaks during deformation when the bowl basket is pulled out.

[0087] In some embodiments, the surface of the limiting member 58 facing away from the mounting member 44 has a guiding inclined surface 64, and the guiding inclined surface 64 is inclined from the direction away from the receiving groove 56 to the direction close to the receiving groove 56.

[0088] Thus, it is convenient for the connecting bar 57 to be inserted into the receiving groove 56.

[0089] Specifically, please refer to Figure 6 , the direction away from the receiving groove 56 is the forward direction, the direction close to the receiving groove 56 is the backward direction, and the guiding inclined surface 64 is inclined from the front to the back direction, so that when the bowl basket is pushed into the cavity from the front to the back, the connecting bar 57 can more smoothly enter the receiving groove 56 along the guiding of the guiding inclined surface 64.
