  • Patent number: 6578587
    Abstract: A dish washing machine according to the present invention has vertically divided upper and lower doors 16 and 17 for covering an opening of a washing chamber. The upper door 16 is opened through its upward pivotal movement about its shafts 20. The lower door 17 is opened through its downward pivotal movement about its shafts 22. The upper door 16 is fully opened through its pivotal movement substantially through 180 degrees. The lower door 17 is opened to a substantially horizontal position. And when the lower door 17 is in this opened state, a basket 4 contained in the washing chamber 3 can be pulled out onto the lower door 17.

  • Patent number: 5893280
    Abstract: By rotating a drum at a low speed, the laundry is redistributed so that the eccentric load due to the laundry comes at a position opposing a balancing chamber. Then, while the drum is rotated at a middle speed, a balancing-water supply valve is opened to supply water from a balancing-water nozzle into a water-guiding chamber provided on the back of the drum. The water supplied flows into the balancing chamber, thus increasing the weight of the balancing chamber. The water supply is continued until the magnitude of the eccentric load of the drum holding the laundry and the water becomes smaller than a predetermined value. After an adequate amount of water is supplied, the total eccentric load is so small that the abnormal vibration does not occur even when the drum is rotated at a high speed for extraction.

  • Patent number: 5545259
    Abstract: In a dish washing machine according to the present invention, the contents of washing and rinsing are changed depending on dirt to prevent water from being uselessly used particularly if the degree of dirt on the dishes is low. Therefore, in the first drainage process in the latter part of the washing, the drainage is first started IS2-1). If 20 seconds have elapsed since the drainage was started, the drainage is stopped (S2-3). If the degree of dirt on the dishes is relatively high to select a sequence X (S2-4), drainage processing is performed on the basis of the contents of operations in the sequence X, after which the program proceeds to the rinsing process (S2-5 to S2-11).
