A spray arm of a dishwasher with a built-in water pump, please refer to figure 1-show, which comprises a spray arm body 1, a motor 2 and an impeller 3.

The spray arm body 1 includes: the upper spray arm cover 11 and the lower spray arm cover 12 are assembled up and down; the nozzle arm body 1 has a mounting position 110 formed at a middle position thereof for mounting the impeller 3, and the mounting position 110 is formed of a rib provided on the nozzle arm upper cover 11 or the nozzle arm lower cover 12. A water inlet 101 is formed on the spray arm lower cover 12 corresponding to the impeller 3, and a water outlet 102 is formed on the spray arm upper cover 11.

The motor 2 includes: the spray arm comprises a motor body 21 and a transmission shaft 22, wherein the motor body 21 is assembled below the spray arm body 1, and the transmission shaft 22 penetrates through the spray arm lower cover 12 to be connected with the impeller 3 and drives the impeller 3 to rotate.

Specifically, as shown in fig. 4, a circular arc-shaped protruding rib is formed in the spray arm body 1, the protruding rib forms a space for installing the impeller 3, the spray arm body 1 is further provided with a baffle 13, the baffle 13 extends from the installation position 110 to two ends of the spray arm body 1, and the baffle 13 extends along the water outlet 102. The water outlet a103 is formed on the mounting position 110, and this design enables a relatively closed space to be formed in the mounting position 110 where the impeller 3 is mounted. When the motor 2 connected below rotates, the blades 31 on the impeller 3 directly push water away from the water outlets A103 on two sides, the water flows along the guide plate 13 and is sprayed out through the water outlets 102 in the flowing process; when the impeller 3 rotates to push away water, the impeller is installed to form a short vacuum inside, then external water is sucked into the spray arm body 1 from the water inlet under the negative pressure of the vacuum inside the spray arm, the rotating blades 31 continue to push the water out of the water outlet 102, and the water is circulated continuously from the water inlet to the inside of the spray arm, which is equal to the structure of a centrifugal water pump.

Referring to fig. 5, the impeller 3 is longitudinally installed in the spray arm body 1, an insertion sleeve 30 for inserting the transmission shaft 22 is formed at the center of the impeller 3, blades 31 are distributed outwards along the insertion sleeve 30, and the blades 31 are vertically arranged to effectively push water out from two sides.

In the structure, a filter screen 4 and a heating plate 5 can be added. It is effective enough to ensure that the residue will not enter the interior of the spray arm body 1 to block the water outlet 102.

The filter screen 4 is arranged between the motor 2 and the spray arm body 1.

The side of the motor body 41 where the transmission shaft 42 is installed is set as an end face, the heating plate 5 is installed on the end face, and the heating plate 5 can heat water.

The filter screen 41 is in a ring shape and is in a sheet shape, a circular through hole 40 is formed in the center of the filter screen 41, the circular through hole 40 is arranged corresponding to the water inlet 101 of the spray arm body 1, the filter screen 41 is buckled with the motor body 41 during assembly, and the edge of the filter screen 41 is tightly matched with the edge of the heating disc 5.

Please refer to fig. 3, a buckle is correspondingly formed on the end surface of the motor body 41 and the bottom surface of the filter screen 41, the buckle is a rotary buckle and has a side opening, the filter screen 41 is installed on the motor body 41 and then is rotated forward, the buckle is correspondingly locked, so that the filter screen 41 cannot be separated from the motor body 41 upward directly, when the filter screen is removed, the filter screen 41 needs to be rotated reversely by applying force, and after the corresponding buckle is separated, the filter screen 41 can be taken out upward.

The clasp 111 is formed at the bottom of the spray arm body 1, and the edge of the circular through hole 40 of the filter screen 41 is clamped into the clasp 111, so that the spray arm body 1 and the filter screen 41 are stably assembled.

After assembling according to the mode, when in use, the water in the dish-washing machine is heated through the heating plate 5, and the water in the dish-washing machine must be filtered through the filter screen 4 before the spray arm body 1 is carried out.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
