Dishwasher float switch control assembly

摘要

A float support includes a guide sleeve extending upwardly from a dishwasher chamber sump for slidable reception of a float stem. The support includes a hollow standpipe having an upper portion, partially defined by an external wall of the guide sleeve along part of its axial height, and a lower portion extending down through the sump in an offset manner. The inverted cuplike float includes a plurality of cavities at least one of which is adapted to entrap air to provide buoyance to the float. A remaining one of the cavities defines a combined float damping and overflow cavity which conceals the upper portion of the hollow standpipe such that the standpipe establishes an air break path between the overflow cavity and atmosphere thereby damping the vertical travel of the float.
