Problems solved by technology

[0002] In existing dishwasher products, most of the spray arms used are fixed in length and non-retractable. They just rotate around the center of the circle, and the area swept by the water column sprayed by the spray arm is also circular. However, due to the The inner cavity is a cube, so there is a phenomenon that the cleaning of the four corners is not clean, that is, there are cleaning dead corners

Embodiment 1

[0026] Embodiment one: as attached figure 1 As shown, this retractable spray arm for a dishwasher includes a fixed part 7, a movable part 4, an inner tank bottom shell 1 and a guide device 5, and the fixed part 7 and the movable part 4 are provided with Water spray hole, the water spray hole communicates with the spray arm seat 8 through the waterway, the movable part 4 is movably sleeved on the fixed part 7, the inner tank bottom shell 1 is provided with a guide rail 2, One end of the guide device 5 is connected to the movable part 4, and the other end is connected to the guide rail 2 and moves in the guide rail 2, so as to drive the movable part 4 to move telescopically along the fixed part 7; The cleaning area of ​​the retractable spray arm is larger than the original coverage area, especially the cleaning effect of the four corner areas is very good, which significantly improves the overall cleaning effect of the dishwasher.

Embodiment 2

[0027] Embodiment 2: In the foregoing embodiment, as attached image 3 As shown, two or more of the movable part 4 and the fixed part 7 are matched and evenly distributed in the circumferential direction on the spray arm seat 8, and through the joint action of the guide device 5 and the internal water pressure of the spray arm seat 8 Realize the stretching motion of movable part 4 down.

Embodiment 3

[0028] Embodiment 3: In the above embodiment, two or more non-telescopic spray arms 3 are also included, and the non-telescopic spray arms 3 are evenly distributed in the circumferential direction on the spray arm seat 8, and are connected with the movable part 4 and the fixed part 7.

Abstract

The invention relates to a retractable spraying arm for a dishwasher and the dishwasher. The retractable spraying arm comprises a fixed part, a movable part, a liner bottom shell and a guide device; water spraying holes are formed in the fixed part and the movable part and communicated with a spraying arm base through waterways; the fixed part is movably sleeved with the movable part, and the liner bottom shell is provided with a guiding rail; one end of the guide device is connected to the movable part, and the other end of the guide device is connected with the guiding rail and moves in the guiding rail, so that the movable part is driven to move along the fixed part in a retractable mode. The retractable spraying arm for the dishwasher and the dishwasher have the advantages that through the design of the retractable spraying arm, when the spraying arm rotates to a dead corner in the rotation process, the spraying arm can extend out a certain length under the guidance effect of guiding wheels, the cleaning area of the spraying arm is increased, and the problem that the dead corners of the dishwasher are not cleaned completely is solved.

Description

technical field [0001] The invention belongs to the technical field of dishwashers, and in particular relates to a retractable spray arm for a dishwasher and the dishwasher. Background technique [0002] In existing dishwasher products, most of the spray arms used are fixed in length and non-retractable.
