Description

Dish washer and washing control method thereof Technical Field The invention belongs to the technical field of dish washers, and particularly relates to a dish washer and a washing control method of the dish washer. Background Along with the improvement of living standard, the requirements of people on living quality are higher and higher, so that the requirements on various aspects such as quality, performance, humanization of use, intellectualization of operation and the like of living goods are also higher and higher. The dish washer also goes into the life of people as a convenient living goods. In principle, a dishwasher is a device for washing dishes by injecting high-pressure washing water through a nozzle, and generally includes a dishwasher liner forming a washing chamber, a dish inlet provided in front of the liner, a door provided at the dish inlet, and a dish rack, a shower, etc. provided in the washing chamber. In order to achieve an ideal cleaning effect, the existing spraying device installed in the dish washer is generally a rotatable spraying arm, a plurality of spraying holes are formed in the spraying arm, the spraying arm is rotatably connected to the inner container body, the spraying arm is communicated with a waterway, and water in the waterway is sprayed out through the spraying holes in the spraying arm to clean tableware placed in the inner container.
