Abstract: The present invention provides a dishwasher which permits cost reductions while enabling increased strength. A reinforcement member is mounted between pillars, which are erected in the corners of a machine chamber, and a functional part for executing washing and rinsing is fixed to the reinforcement member. Here, an example of the functional part is a washing pump for delivering washing water. Furthermore, another example for the functional part is a connecting part for connecting electrical wiring between a control box and a detergent supply device or a booster or the like.

Abstract: In the dishwasher, a washing water distribution pipe on which washing nozzles are installed is arranged within a washing chamber, and is connected removably to a first connecting pipe that communicates with the outlet side of a washing pump. In the same way, a rinsing water distribution pipe on which rinsing nozzles are installed is arranged within the washing chamber, and is connected removably to a second connecting pipe that communicates with the outlet side of a rinsing pump. These connections are made within a washing water tank in the bottom of the washing chamber, therefore the washing water distribution pipe and the rinsing water distribution pipe can be easily installed and removed from the washing chamber. Moreover, the washing water distribution pipe and the rinsing water distribution pipe are unitized, so handling is extremely easy.

Abstract: A dishwasher is a type in which a part of wash water contained in a wash water tank is replaced with rinse water every washing cycle. The dishwasher determines whether a present washing cycle is in timing of executing a detergent increase supply processing or in timing of executing a detergent normal supply processing (S304). Based on this determination result, by the execution of the detergent increase supply processing, a supply amount of the detergent is increased (S309). Consequently, in the dishwasher, the detergent concentration in the wash water is properly adjusted.

Abstract: To provide a dishwasher for which the washing water distribution pipe provided with the washing nozzles and the rinsing water distribution pipe provided with the rinsing nozzles can be easily installed and removed from the washing chamber. In the dishwasher 1, a washing water distribution pipe 21 on which washing nozzles 12, 14 are installed is arranged within a washing chamber 3, and is connected removably to a first connecting pipe 31 that communicates with the outlet side of a washing pump 19. In the same way, a rinsing water distribution pipe 27 on which rinsing nozzles 13, 15 are installed is arranged within the washing chamber 3, and is connected removably to a second connecting pipe 33 that communicates with the outlet side of a rinsing pump 24. These connections are made within a washing water tank 17 in the bottom of the washing chamber 3, therefore the washing water distribution pipe 21 and the rinsing water distribution pipe 27 can be easily installed and removed from the washing chamber.
