AI Technical Summary

Technical Problem

During use, the spray device of the cleaning machine may become stuck due to excessively high kitchen utensils, improper placement by the user, falling of light items during washing, or accumulation of contaminants, resulting in insufficient cleaning.

Method used

By detecting the change in pump output power before and after the rotation switching of the spray device, it can be determined whether the spray device is operating normally, ensuring that the spray mode switching is effective and preventing blockage.

Benefits of technology

Effectively detect whether the spray device is rotating normally to ensure cleaning effect, prevent insufficient cleaning, and improve the cleaning ability of the cleaning machine.

Abstract

The embodiment of the application discloses a detection method, a control device and a cleaning machine for a spraying device of the cleaning machine. The cleaning machine comprises a pump and a spraying device. The pump is used to deliver cleaning liquid to the spraying device. The spraying device comprises at least two flow channels with different liquid outlet areas. The spraying device has at least two different spraying modes. The spraying device switches between the at least two spraying modes by rotation. In different spraying modes, the cleaning liquid flows through different flow channels of the spraying device. The detection method comprises the following steps: S1, detecting a first output power of the pump before the spraying mode is switched; S2, detecting a second output power of the pump after an operation for switching the spraying mode is performed; and S3, determining whether the spraying device is normally operated according to the first output power and the second output power.
