The utility model relates to a spraying arm for a cleaning
machine and the cleaning
machine, the spraying arm comprises a spraying arm main body, the spraying arm main body is provided with a plurality of water spraying holes, the spraying arm main body is also provided with a water outlet, the water outlet is connected with a
nozzle capable of rotating relative to the spraying arm main body, the
nozzle is provided with a spraying hole, and the spraying hole is communicated with the spraying arm main body. A top cover capable of rotating relative to the
nozzle is arranged at the top of the nozzle, and water passing holes which are arranged corresponding to the spraying holes and can rotate along with the top cover to adjust the alignment degree with the spraying holes are formed in the top cover. When tableware to be cleaned is severely dirty, the
water flow passing area can be reduced by reducing the alignment degree of the water passing holes and the spraying holes, the
water flow intensity and the
impact force to pollutants are increased, and the cleaning effect is improved. When the
dirt degree of tableware is small, the
water flow passing area can be increased,
dirt on the surfaces of bowls and dishes can be rapidly cleaned, the cleaning efficiency is improved, the cleaning effect and the cleaning efficiency can be well balanced according to the
dirt degree of the tableware, energy is saved, and consumption is reduced.
