By means of according to sensor of the invention unit can during operation control program flow.Therefore it can especially examine Survey：Spray arm rotates with whether meeting regulation, and which spray arm has improperly misdeed.
By using infrared ray, especially spray arm motion reliable and the also ring in vessel washer working chamber Largely glitch-free detection is feasible during operation under the conditions of border.Big by infrared ray beam reaches model Enclose, spray arm can also be in the larger distance from sensor unit or in unfavorable position state, for example orient on angle Unfavorable position state on be detected.
The principle of work and power of sensor unit is based on herein：Infrared ray is radiated by RF transmitter, anti-in working chamber Penetrate and detected again by infrared receiver.
In order to identify that spray arm rotation for example can be by the reflection to receiver that is securely in machine operation chamber Device reflects infrared ray beam, wherein, the changes of IR beams is detected for example in intensity, the change due to rotation spray arm, The structural detail that is fastened on spray arm is caused due to the water jet or the cleaning solution beam that are come out from spray arm.
Here, individual member or anyway all existing structural detail, such as work can be used as fixed reflector Make a region in cavity wall portion.
In another embodiment of the present invention, as the beam emitted by IR transmitters due to the spray arm or therewith of rotation Element, a region of such as spray arm, the individual reflector element being fastened on spray arm, the water-jet of spray arm nozzle of connection Beam or cleaning solution beam etc. are reflected on receiver.These reflections are therefore directly interrelated with the rotation of spray arm.
The change of these reflections and/or reflection enables in particular to significantly detect, if they are in transmitter and/or reception Occur near device, such as due to directly rotating through the spray arm or water jet of transmitter and/or receiver.
The present invention a special embodiment in, cause in the following way infrared ray energy reliable detection it is anti- Penetrate, i.e. at least one spray arm nozzle is orientated in this wise so that water jet or clean cleaning solution cleaning solution beam with it is infrared The beam light path of linear light is intersected at least in part.Here, the reflection according to desired by the present invention can be drawn by water or cleaning solution Rise.
