The left sprayer 33 and the right sprayer 34 are installed on the left and right sides of the dishwasher and can generate horizontal high-pressure water columns to wash the sides of the tableware, while the lower sprayer 35 is installed at the bottom of the dishwasher and can generate an upward-spraying water column to wash the tableware. By extending the elbow 38 into the first conduit 36, the high-pressure water in the water distribution pipe 11 enters the first conduit 36 ​​and is sprayed upward from the lower spray plate 37. The upper surface of the lower spray plate 37 is inclined so that the water outlet direction can be inclined toward the direction in which the tableware is placed, so that the water column acts entirely on the tableware, thereby increasing the cleaning efficiency.

[0052] The left sprinkler 33 and the right sprinkler 34 are symmetrically arranged on both sides of the mounting frame 7. The left sprinkler 33 and the right sprinkler 34 both include a second conduit 39, a U-shaped elbow 40 and a side injection plate 41. The height of the second conduit 39 is greater than the height of the first conduit 36. The bottom of the second conduit 39 is connected to the mounting block 30. The elbow 38 on the left side extends to the second conduit 39 on the left side, and the elbow 38 on the right side extends to the second conduit 39 on the right side. The U-shaped elbow 40 is installed on the second conduit 39. Blocks 42 are provided on both sides of the bottom plate 4. The U-shaped elbow 40 passes through the block 42. The side injection plate 41 is installed on the inner side wall of the block 42, and the side injection plate 41 is connected to the U-shaped elbow 40. The functions of the left sprayer 33 and the right sprayer 34 are almost the same, which is to turn the upward flowing water flow to spray in the horizontal direction all the time, so that the sides of the tableware can be rinsed and cleaned. This is very different from the traditional dishwasher and can reduce the cleaning blind spot. At the same time, the second conduit 39 plays a diversion role for the water in the water distribution pipe 11. The setting of the elbow 38 realizes the connection between the second conduit 39 and the water distribution pipe 11, so that the water in the water distribution pipe 11 can be transferred to the second conduit 39, and the U-shaped bend 40 can change the direction of the upward pipeline by its own special shape, and the water column flowing through the U-shaped bend 40 will be sprayed from the side spray plate 41 in the horizontal direction. Most of the U-shaped bend 40 is installed inside the block 42. The block 42 can reduce the vibration of the U-shaped bend 40, making the installation of the U-shaped bend 40 more stable and generating less noise during spraying. At the same time, the block 42 can reduce the contact between the outer side of the U-shaped bend 40 and the washing water, and can reduce the possibility of dirt and the like adhering to the outer surface of the U-shaped bend 40.

[0053] The upper shower 32 includes a third conduit 43, a connecting elbow 38 and an upper spray plate 45. The height of the third conduit 43 is greater than that of the second conduit 39. The bottom of the third conduit 43 is connected to the mounting block 30. The elbow 38 located at the rear side extends into the third conduit 43. The top of the third conduit 43 is connected to a connecting elbow 44. The top of the upper spray plate 45 is fixedly connected to the other end of the connecting elbow 44. The upper spray plate 45 is arranged toward the bottom plate 4. The upper shower 32 can drain the water in the assembly box 8 to a certain height, so as to realize the spray washing of the tableware at the top of the tableware. The third conduit 43 has a certain height. The elbow 38 extends into the third conduit 43 to realize the communication between the third conduit 43 and the water distribution pipe 11. The connecting elbow 44 bends the upward pipeline downward, so as to ensure that the water flows downward and smoothly at the upper spray plate 45.
