the spraying arm (4) is a movable spraying arm, and the monitoring module (1) comprises a signal induction module (101) and a signal trigger module (102) which are arranged on the outer side of the dishwasher tank body (10); the signal induction module (101) can be periodically connected with and disconnected from the signal trigger module (102) along with the rotation of the spray arm (4); the signal triggering module (102) is arranged between the signal sensing module (101) and the spray arm (4), monitors the signal of the signal sensing module (101), and sends an alarm signal to the central processing module (2) when an alarm event is found; the display module (3) comprises a spraying indication pattern (5) for displaying the working state of the spraying arm (4), the spraying indication pattern (5) at least comprises a first display state (501) and a second display state (502), when the spraying arm (4) of the dishwasher works normally, the spraying indication pattern (5) is switched between the first display state (501) and the second display state (502), and when the spraying arm (4) generates an alarm event, the spraying indication pattern (5) is changed into a static state from the switching state and flickers;

and/or the spray arm (4) is a static spray arm, the monitoring module (1) is a sensor for sensing a spray state, and when the sensor senses that the spray state of the static spray arm is in a stagnation state or the pressure is increased due to unsmooth spray, the sensor sends an alarm signal to the central processing module (2).

2. The dishwasher spray alarm device of claim 1, wherein:

one end of the spray arm (4) is provided with a magnetic unit (9);

the magnetic unit (9) interacts with the signal induction module (101), and the signal induction module (101) is triggered to be periodically communicated with the signal trigger module (102).

3. The dishwasher spray alarm device of claim 2, wherein: the magnetic unit (9) is a magnet arranged at one end of the spray arm (4).

4. The dishwasher spray alarm device of claim 2, wherein: the signal induction module (101) receives signals of the magnetic unit (9) and can be periodically connected with and disconnected from the signal trigger module (102) along with the rotation of the spray arm (4).

5. The dishwasher spray alarm device of claim 1, wherein: the signal induction module (101) is a single reed.

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.
