Problems solved by technology

[0002] In the existing dishwasher products, most of the spray arms used are of fixed length. Since the spray arm rotates around the central axis when the spray arm is working, in the state where the length of the spray arm is fixed, the spraying area of ​​the spray arm is only one It is round, and the inner tank is generally square, so there are cases where the four corners cannot be cleaned, which has a great impact on the overall cleaning effect of the dishwasher

Abstract

The invention relates to a telescopic spray arm for a dish washing machine and the dish washing machine. The telescopic spray arm comprises a fixed part, a movable part, a spray arm base and a guidingdevice, the fixed part and the movable part are both provided with water-spouts which are communicated with a spray arm frame through a waterway, the spray arm base is located on an inner container bottom shell, the movable part is movably arranged on the fixed part in a sleeving mode, the guiding frame is arranged on the spray arm base, one end of the guiding device is connected to the movable part, and the other end of the guiding device is connected with the guiding frame and move in the guiding frame, so that limitation of displacement distance is achieved when the movable part moves along the fixed part in a telescopic mode. The telescopic spray arm has the advantages that by means of the design of the telescopic spray arm, when the spray arm rotates around a center shaft, the telescopic spray arm can be elongated when the spray arm frame rotates to the four corners under the guiding effect of the guiding frame on the spray arm base, the spray arm spray area is increased, and theproblem that the four corners of the dish washing machine 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.
