Abstract

A multipurpose parts washer may include an automatic cleaning portion, with a first cleaning chamber for spraying parts, a second cleaning chamber for soaking parts, and a manual cleaning portion. Cleaning solution may be disposed in a reservoir of the first cleaning chamber at a reservoir level and in the second cleaning chamber at an agitation level that is above the reservoir level. The manual cleaning portion may be configured as a sink that is movably connected to the automatic cleaning portion to provide selective access thereto. A first thermal energy source may be used to heat the cleaning solution to a first temperature for the second cleaning chamber and the manual cleaning portion and a second thermal energy source may be used to heat the cleaning solution to a spray temperature greater than the first temperature for the first cleaning chamber. The multipurpose parts washer includes three cleaning portions. All portions use cleaning solution from a single pump, a reservoir portion to collect and store the important volume of cleaning solution and debris from the washing process, a single controller interface operated from a display, and a thermal energy source for heatin…
