Filed:

Sep 7, 2001

Appl. No.:

09/948213

Inventors:

Lenard Deiterman - Springdale AR 72764
Alfred Lemke - Siloam Springs AR 72761
Carl Lemke - Fayetteville AR 72703

International Classification:

A47L 1134

US Classification:

15320, 15339

Abstract:

An apparatus for cleaning floors which recycles waste heat and water to provide greater efficiency. An internal combustion engine is used to power the apparatus. Heat from the engines lubricant is used to heat the wash solution applied to the floor. Heat from the engines cooling air, radiator, and catalytic converter is used to dry the cleaned floor. A drying brush is also used to accelerate drying. Used rinse water is recycled for use as wash solution. Exhaust from the engine is used to preheat the floor to be cleaned. The engine may be used to propel the apparatus.

Clarke Industries, Inc. - Springdale AR

International Classification:

F22B 3710

US Classification:

122248

Abstract:

A high pressure washer of this invention comprises a heat exchanger for heating a cleaning fluid, and a dispenser for dispensing heated cleaning fluid under pressure onto a surface to clean it. The heat exchanger comprises a tubular casing and a generally coaxial tubular heat shield inside the casing defining a combustion chamber. A burner is mounted adjacent a first end wall of the casing for discharging flames and hot combustion gases into the combustion chamber. A heating coil inside the casing extends longitudinally with respect to the casing for containing cleaning fluid to be heated. The heating coil comprises a length of unfinned tubing disposed in a gap between the heat shield and a second end wall of the casing, and a length of finned tubing in the annular space between the heat shield and the casing. The burner is operable to emit flame and hot gases of combustion into said combustion chamber in a direction toward the second end wall of the casing. The heat shield serves to protect the finned tubing by directing the hot gases of combustion for contact first with said unfinned tubing, resulting in cooling of the gases, followed by contact with the finned tubing in said annular space, thereby enhancing the heat transfer between the gases and the fluid contained within the heating coil.

US Classification:

3408154

Abstract:

An indicator junction module for connecting the electrical components of a pressure washer for dispensing a cleaning fluid under pressure. The indicator junction module includes terminal connectors for receiving leads from the components and indicator circuits corresponding to the components. At least one of the indicator circuits has one of its terminals electrically connected to an indicator device and the other of its terminals electrically connected to another indicator circuit. Each indicator device provides a visual indication of a condition of the corresponding component. The indicator junction module also includes an enclosure for enclosing the indicator circuits wherein the indicator devices are visible from outside the enclosure to an operator of the pressure washer and a portion of each terminal connector is external to the enclosure. Each terminal connector is electrically connected to one of the indicator circuit terminals so that the components connected to the terminal connectors are electrically connected to each other via the indicator circuits. Other features are also disclosed including a method of manufacturing the pressure washer indicator module.
