Sprayer of dish washing machine and dish washing machine

Abstract

The invention relates to a sprayer of a dish washing machine. The sprayer comprises a water pipe assembly, a main spraying arm rotatably connected to the water pipe assembly, one or more sub sprayingarms rotatably installed at the end of the main spraying arm and an annular slideway arranged at the lower side of the main spraying arm and slidingly matched with the sub spraying arms. When the mainspraying arm rotates, the sub spraying arms slides along the annular slideway, and under the limit of the annular slideway, the sub spraying arms rotate relative to the main spraying arm. The invention further relates to the dish washing machine provided with the sprayer. Through cooperation of the sub spraying arms and the annular slideway, the water spraying range of the main spraying arm is enlarged, the sprayer has the advantages of being large in spraying covering range and particularly suitable for a rectangular liner of the dish washing machine, the cleaning dead corner can be reduced,and the working efficiency of the dish washing machine is improved.

Description

technical field [0001] The invention relates to dishwashing equipment, in particular to a shower for a dishwasher and a dishwasher equipped with the shower. Background technique [0002] Existing dishwasher sprinklers generally expand the spray range by rotating, but the inner tank of a general dishwasher is square, and the circular coverage sprayed by a single rotating sprinkler is easy to produce Washing dead corners, especially rectangular inner tanks, are more likely to produce dead corners, resulting in unsatisfactory cleaning effect of the dishwasher. The Chinese utility model patent with the application number: 201120253079.0 discloses a spray arm structure of a dishwasher, which includes a water pipe assembly and a main spray arm connected to the water pipe assembly, and is characterized in that a water pipe branch is also provided on the water pipe assembly , the auxiliary spray arm is connected to the water pipe branch. The beneficial effect of the utility model ...

AI Technical Summary

Problems solved by technology

Although the patent expands the spraying area by increasing the auxiliary spray arm, since the main spray arm and the auxiliary spray arm spray out a circular coverage area, there will still be cleaning dead angles. If the overlapping spraying range is simply to reduce the cleaning dead angle, will result in a decrease in spray cleaning efficiency
