ある。[Problem to be solved by the invention] In the above conventional example,
When the cleaning water in the cavity is drained to a certain extent by the drain pump, the water level in the cavity decreases, and the drain pump becomes air-clogged, which prevents the water from being drained. Since the cleaning water that is no longer drained accumulates as residual water in the water suction pipe, water scale adheres to the portion formed of the translucent material. Therefore,
There is a risk that the transmittance will decrease and the cleaning state detection performance will deteriorate.

At this time, the cleaning water that could not be drained away accumulates in the pipe as residual water. However, the residual water remaining in the pipe after draining the part of the water flow path from the outlet of the water reservoir section to the suction port of the cleaning pump where the permeation detection means is attached is compared to the other part of the water flow path. The transmission detection part is not immersed in residual water because it is raised so that it is exposed from the inside. Therefore, the transmission part is not contaminated by water stains from the washing water.

浄工程を制御する。In the above configuration, the water supply valve 22 is opened and the cleaning water supplied into the cavity 1 from the water supply port 23 is transferred from the recess 5 on the bottom of the cavity 1 to the pipe by rotating the cleaning/drainage pump 7 in the normal direction. The water is sucked into the pump casing 11 through the water outlet 12 and sent to the nozzle 3 through the discharge port 9. During this time, the light receiving element 30 detects the light emitted from the light emitting element 29 toward the light receiving element 30 via the washing water passing through the pipe 12. Since the light transmittance of the cleaning water changes depending on the degree of contamination, the degree of contamination of the cleaning water is detected based on the amount of light received by the light receiving element 30, and the control unit 25 controls the cleaning process based on this.

ることがなくなる。When the cleaning process is completed, the cleaning/drainage pump 7 is reversed and the water is drained through the drainage pipe 21. Pump casing 1 to lower the height of the dishwasher
Since the suction port 8 of 1 is opened toward the side, once a certain amount of water has been drained, the washing/drainage pump 7 will generate air bubbles and become unable to drain water, remaining in the recess 5, pipe 12, and pump casing 11 as residual water. . However, the outlet 6 of the recess 5
Since the washing/draining pump 7 is installed so that the suction port 8 of the pump casing 11 is higher, the water surface of the remaining water is at the position B in FIG. 2. Therefore, the light emitting transmitting section 27 and the light receiving transmitting section 28 provided on the surface opposite thereto are above the water surface of the remaining water and are not immersed in the remaining water. This will prevent it from getting dirty and cloudy.
