題があった。Problems to be Solved by the Invention However, with such a structure, if a factor that hinders the rotational movement of the discharge nozzle 4 or causes a forced stop occurs for some reason, a fixed price for the dishwashing ability is generated. It will be. That is, when tableware, chopsticks, spoons, etc. fall from the tableware basket 5 or project from the tableware basket 5 and enter the rotational movement range of the discharge nozzle 4, the rotation operation of the discharge nozzle 4 is reduced or stopped. Further, when the discharge capacity of the cleaning pump 2 decreases due to a decrease in the cleaning water level or the like, the discharge pressure of the discharge nozzle 4 decreases, that is, the rotational performance deteriorates. For these reasons, there is a problem in that the tableware stored in the tableware basket 5 is not sprayed with cleaning water due to a reduction in the rotational operation performance of the discharge nozzle 4 or a decrease in the discharge pressure, and the ability to wash the tableware deteriorates.

合を報知する手段として適切であることによる。Embodiment One embodiment of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, the light-emitting element 6 is provided on the side surface 1a of the cleaning tank 1, and the cleaning tank 1 on the side opposite to the mounting portion of the light-emitting element 6 is provided.
The light receiving element 7 is provided on the side surface portion 1b of the. At this time, the mounting height of the light emitting element 6 and the light receiving element 7 is the rotational movement height of the discharge nozzle 4. Further, as shown in FIG. 2, the light emitting element 6 and the light receiving element 7 are mounted on the plane at positions where the light emitting element 6 and the light receiving element 7 are blocked when the ejection nozzle 4 is rotationally moved.
With the above configuration, the light emitting element 6 emits light during the operation of the cleaning pump 2, so that the light receiving element 7 blocks the light from the light emitting element 6 twice during one rotation of the discharge nozzle. From this, the number of times light is blocked within a certain period of time is detected, and if the number of rotations of the discharge nozzle is reduced or the discharge nozzle is stopped for some reason, an abnormality is notified. This means that the decrease in the rotation speed of the discharge nozzle 4 becomes unstable, that is, a factor that hinders the rotation operation of the discharge nozzle 4 has occurred or the cleaning pump capacity has deteriorated. This is because it is appropriate as a means for informing.
