6. A dishwasher spray alarm unit according to any one of claims 1 to 5 wherein: the use method of the spraying alarm device of the dishwasher comprises the following specific steps:
s1, starting the dishwasher to work, and rotationally spraying by a spraying arm (4);
s2, when one end of the spray arm (4) provided with the magnetic unit (9) is close to the signal induction module (101), the signal induction module (101) is communicated with the signal trigger module (102);
s3, when one end of the spray arm (4) provided with the magnetic unit (9) is far away from the signal induction module (101), the signal induction module (101) is disconnected from the signal trigger module (102);
s4, when the spray arm (4) stops rotating, the communication state of the signal sensing module (101) and the signal triggering module (102) is a constant state, and the signal triggering module (102) sends an alarm signal to the central processing module (2).
7. A dishwasher, characterized by: a dishwasher spray alarm device comprising a dishwasher as claimed in any one of claims 1 to 5.
