Therefore, in the dishwasher 1, it is possible to prevent the washing water from getting caught in the treatment agent supply port 10H and its surroundings and becoming dirty with high certainty. Further, in the dishwasher 1, for example, even if the cover body 15 is removed from the upper end of the storage tank 10 and the treatment agent supply port 10H remains open, the washing water infiltrates through the treatment agent supply port 10H. It is possible to suppress this with high certainty. As a result, it is possible to prevent the detergent component and the dirt component contained in the washing water from being mixed into the rinse R1 and deteriorating the quality of the rinse R1.

Further, in the dishwasher 1, as shown in FIGS. 4 and 5, the treatment agent supply port 10H is arranged in front of the sealing region E1. With this configuration, the moving distance required when the user moves the moving body 6 to the drawer position shown in FIG. 2 to expose the treatment agent supply port 10H to the outside of the housing 9 can be shortened, so that the rinse R1 can be used as the treatment agent. The storage tank 10 can be replenished more easily from the replenishment port 10H. Further, with this configuration, when the moving body 6 is pulled out to the pull-out position, it is possible to highly reliably suppress the water droplets and the like adhering to the back surface of the lid 8 from dripping onto the treatment agent supply port 10H.

Further, in the dishwasher 1, as shown in FIG. 5, the treatment agent supply port 10H is arranged on the second upper surface 72, which is a surface facing upward between the front surface 70F of the door body 70 and the sealing region E1. Has been done. With this configuration, the rinse R1 is treated with the rinse R1 as compared with the case where the treatment agent supply port 10H is arranged on the surface facing left or right between the front surface 70F of the door body 70 and the sealing region E1. The storage tank 10 can be replenished more easily from the replenishment port 10H.

Further, in the dishwasher 1, the user interface 79 having the operation instruction unit 79A and the display unit 79B is arranged on the first upper surface 71 of the door body upper surface cover 77 located above the treatment agent supply port 10H. .. With this configuration, when the rinse R1 is replenished, even if the user fails to insert the rinse R1 into the treatment agent supply port 10H, the rinse R1 is unlikely to sneak into the user interface 79. As a result, in the dishwasher 1, the user interface 79 can be prevented from being contaminated by the rinse R1 with high certainty.

Further, in the dishwasher 1, the cover body 15 that closes the treatment agent supply port 10H can highly reliably suppress foreign matter from entering the storage tank 10 from the treatment agent supply port 10H.
