  • Patent number: 5320120
    Abstract: A dishwashing machine includes a wash chamber and spray distribution mechanism to spray fluid over articles in the chamber. A recirculation sump at the bottom of the chamber receives fluid from the chamber and a first pump, driven by a relatively large motor, draws fluid from the sump and discharges it to the spray mechanism. A filter is positioned to remove soil particles from the recirculated fluid and a collection chamber collects filtered soil particles. The collection chamber is connected to a drain through a first one way valve. A drain pump, driven by a relatively small motor, is connected between the lower portion of the recirculation sump and the collection chamber. Another one way valve permits flow from the recirculation sump to the collection chamber while preventing reverse flow.
