[0039] like Figures 1 to 5 As shown, the utility model proposes a spray arm 1, and the spray arm 1 includes:

[0040] The arm 101 is provided with a water hole 113;

[0041] The transfer chamber 102 has a first side and a second side. A water passage is provided inside the transfer chamber 102. One end of the water passage is connected to the first side, and the other end is connected to the second side. The first side is connected to the arm 101, and the water passage is connected to the water hole 113.

[0042] A nozzle 103 is connected to the second side, and the nozzle 103 has a receiving cavity and a water sprinkling hole, and the receiving cavity is connected to the water sprinkling hole and the water passage; and

[0043] The vibration module is disposed on the transfer bin 102 , and the vibration generated by the vibration module sprinkles out the water remaining in the transfer bin 102 and the spray head 103 .

[0044] In this embodiment, the spray arm 1 includes an arm 101, a transfer bin 102, a nozzle 103 and a vibration module. The arm 101 is provided with a water hole 113. The transfer bin 102 is arranged between the arm 101 and the nozzle 103. The first side of the transfer bin 102 is connected to the arm 101, and the other side is connected to the nozzle 103. A water passage is provided inside the transfer bin 102. One end of the water passage is connected to the water hole 113, and the other end is connected to the accommodating chamber in the nozzle 103. A water sprinkling hole is also provided on the accommodating chamber. The water flowing in from the arm 101 can flow to the outside through the water sprinkling hole. The vibration module is arranged on the transfer bin 102, and the vibration module can provide vibration, and the vibration energy is transmitted to the transfer bin 102 and the nozzle 103, and the residual water in the transfer bin 102 and the nozzle 103 will flow under the vibration, and then the water in the transfer bin 102 will flow into the nozzle 103, and the water in the nozzle 103 can flow to the outside through the water sprinkling hole. This method can remove the residual water in the transfer bin 102 and the nozzle 103, and avoid the problem of odor in the spray arm under the premise of residual water.

[0045] The working principle of the vibration water removal provided by the utility model is: when the spray component is spraying water normally, the vibration module will not have any action; when the spray component is no longer spraying water, the vibration module will transmit vibration, and the vibration will be transmitted to the transfer bin 102 and the nozzle 103, thereby removing the water remaining in the transfer bin 102 and the nozzle 103.

[0046] Further, if Figures 1 to 3 As shown, the vibration module includes:

[0047] The air supply device 104 has an air outlet;

[0048] An air duct 112 is disposed on the arm 101 , and the air duct 112 has a first end and a second end, and an air outlet of the air supply device 104 faces the first end of the air duct 112 ;

[0049] An impeller 105 is rotatably disposed on the transfer bin 102, and the blades of the impeller 105 face toward the second end of the air duct 112;

[0050] Transmission parts, arranged on the transfer bin 102;

[0051] The vibration block 106 is rotatably set on the transfer bin 102. The rotation center of the vibration block 106 is eccentrically set. The impeller 105 drives the vibration block 106 to rotate with the help of a transmission member. The rotation of the vibration block 106 causes the transfer bin 102 and the nozzle 103 to vibrate.

[0052] In this embodiment, the vibration module includes an air supply device 104, an air duct 112, an impeller 105, a transmission member and a vibration block 106. The air supply device 104 is arranged on the arm 101 and is located at the end of the arm 101. The air duct 112 is opened on the arm 101. The air supply device 104 has an air outlet. The air duct 112 has a first end and a second end. The first end faces the air outlet of the air supply device 104, and the second end faces the impeller 105. The impeller 105 is rotatably arranged on the transfer bin 102. The transmission member is arranged On the transfer bin 102, the transmission member can transmit the power on the impeller 105 to the vibration block 106. The vibration block 106 is rotatably set on the transfer bin 102. The rotation center of the vibration block 106 is eccentrically set, so that the vibration block 106 will impact the transfer bin 102 during the rotation process. Since this impact occurs periodically, the impact within multiple cycles will evolve into vibration, thereby realizing the vibration energy provided by the vibration module to the transfer bin 102 and the nozzle 103.

[0053] When the vibration module needs to work, the air supply 104 is started, and the air flow generated by the air supply 104 is transmitted to the impeller 105 through the air duct 112.

[0060] Further, if Figures 1 to 4 As shown, the air inlet and the air outlet are located on symmetrical sides of the rotation axis of the impeller 105 .

[0061] In this embodiment, in order to allow the flowing gas to provide the impeller 105 with the maximum rotational power, the air inlet and the air outlet on the protective cover 109 are arranged in a circularly symmetrical form. In a practical application, the outer wall of the protective cover 109 is cylindrical, so in order to ensure that the flowing gas has the maximum stroke in the protective cover 109, it is best to arrange the air inlet and the air outlet in a circularly symmetrical form.

[0062] Further, if Figure 3 and Figure 4 As shown, a snap-fit ​​protrusion 110 is provided on the protective cover 109 , and a snap-fit ​​hole 111 is provided on the outer wall of the transfer bin 102 . The protective cover 109 is connected to the transfer bin 102 by means of the snap-fit ​​protrusion 110 inserted into the snap-fit ​​hole 111 .

[0063] In this embodiment, in order to facilitate the installation and removal of the protective cover 109, a clamping protrusion 110 is provided on the protective cover 109, and a clamping hole 111 is provided on the outer wall of the transfer bin 102. The clamping protrusion 110 has a certain elasticity, and the clamping protrusion 110 can penetrate into the clamping hole 111 through its own deformation, and can be separated from the clamping hole 111 again by its own elasticity.

[0064] Further, if Figure 2 As shown, the air duct 112 and the water hole 113 are arranged in parallel.

[0065] In this embodiment, in order to improve the overall spatial layout of the equipment, the air duct 112 and the water hole 113 are arranged in parallel, so that the air supply device 104 can be set at the end of the arm 101, thereby avoiding the impact on the spatial layout of the arm 101.

[0066] Further, if Figure 2 As shown, the water hole 113 is arranged along the length direction of the arm 101 and passes through both ends of the arm 101.

[0067] In this embodiment, in order to make full use of the structure of the arm 101, the water hole 113 is arranged along the length direction of the arm 101, and the water hole 113 runs through both ends of the arm 101. This arrangement can make the nozzle 103 be located at a more suitable position, so that the water sprayed by the nozzle 103 can better fill the entire space.

[0068] like Figures 6 to 8 As shown, the utility model further provides a dishwasher, which comprises the spray arm 1 of any one of the above items.

[0069] Furthermore, the dishwasher also includes an inner tank 2 and a bowl basket assembly 3 . The bowl basket assembly 3 and the spray arm 1 are both arranged in the inner tank 2 , and the spray head 103 is located below the bowl basket assembly 3 .
