AI Technical Summary
Existing dishwasher spray arms may stop rotating or rotate slowly due to friction, limescale, or foreign objects, resulting in a decrease in cleaning efficiency that cannot be detected in time, affecting cleaning performance and potentially damaging components such as the motor.
Design a spray structure including multiple spray arms, triggering elements and detection elements. The movement of the spray arms is monitored by photoelectric sensors or other detection methods. The control element determines whether the spray arms are normal, issues an alarm or suspends cleaning in a timely manner, and locates and eliminates the fault.
It enables timely detection of spray arm malfunctions, ensures cleaning effectiveness, avoids damage to components such as motors, and improves cleaning efficiency and safety.

Abstract
Claims
1. A spray structure, characterized by, The spray structure includes: The inner shell (10) has an inner cavity (11) inside; Multiple spray arms (20) are spaced apart from each other in the inner cavity (11), and each spray arm (20) is configured to reciprocate within the inner cavity (11). Each spray arm (20) has a detection position during the movement. Multiple triggers (21) are respectively provided on all of the spray arms (20); The detection element (30) is located in the inner cavity (11). When any of the spray arms (20) passes through the detection position, the corresponding trigger element (21) on the spray arm (20) can trigger the detection element (30) and cause the detection element (30) to output a detection signal. The control unit is communicatively connected to the detection unit (30) and is used to determine whether each of the spray arms (20) is moving normally based on the detection signal.
2. The spray structure of claim 1, wherein When the trigger (21) on different spray arms (20) triggers the detection element (30), the detection signal output by the detection element (30) is different.
3. The spray structure according to claim 1 or 2, characterized in that The detection element (30) is a photoelectric sensor (31), and the trigger element (21) is a reflector (23).
4. The spray structure of claim 3, wherein Each of the spray arms (20) is rotatably disposed in the inner cavity (11) about a rotation axis, the rotation axis intersects the longitudinal direction of the spray arm (20), and the rotation axes of each spray arm (20) are parallel to each other; all the spray arms (20) are arranged sequentially at intervals in the direction of the rotation axis. Each of the spray arms (20) has a reflector (23) on one end face in its longitudinal direction. The photoelectric sensor (31) is located on the inner wall of the inner cavity (11). When any of the spray arms (20) passes the detection position, the photoelectric sensor (31) is located on the side of the spray arm (20) where the reflector (23) is located.
5. The spray structure of claim 3, wherein The reflectivity of the reflectors (23) on each of the spray arms (20) is different; And / or, the reflective wavelengths of the reflectors (23) on each of the spray arms (20) are different; And / or, the reflective color of the reflectors (23) on each of the spray arms (20) is different.
6. The spray structure of claim 5, wherein The spray structure also includes a filter, which is communicatively connected to the photoelectric sensor (31) and the control unit respectively. The filter is used to distinguish the signal of the photoelectric sensor (31) to obtain the detection signal corresponding to each spray arm (20) and transmit it to the control unit.
7. The spray structure of claim 1, wherein The spray structure also includes an alarm component, which is communicatively connected to the control component. The control component is used to control the alarm component to issue an alarm signal when it is determined that the spray arm (20) is moving abnormally.
8. The spray structure of claim 1, wherein The spray structure also includes a water outlet, which is connected to the spray arm (20). The spray arm (20) is configured to reciprocate under the action of the water flow output by the water outlet. The water outlet component is communicatively connected to the control component. The control component is used to increase the flow rate and / or flow rate of the water output from the water outlet component when it is determined that the movement of the spray arm (20) is abnormal.
9. The spray structure of claim 8, wherein, The control component is also used to control the water outlet component to stop operating after a preset time when it is determined that the spray arm (20) is moving abnormally.
10. A dishwasher, characterized in that Includes the spray structure as described in any one of claims 1-9.
