Embodiment Construction

[0022] Referring now in particular to the drawings, there is shown an exemplary pressure washer 10 in accordance with the present invention which generally comprises a wheeled frame housing a liquid pump 12, an internal combustion engine powered by gasoline for operating the pump 12 11, and a wand or spray gun 15 connected to the pressure washer via a high pressure fluid delivery hose 18. The pump 12 has an inlet 16 connectable to a liquid supply, such as a household outlet, via a garden hose 17 or the like. The joystick 15 typically includes a nozzle 15a and a trigger valve 15b of known type, allowing the operator to controllably direct a stream of pressurized liquid towards the substrate surface to be cleaned. The high pressure hose 18 preferably has a reinforced structure as disclosed in US Pat. No. 5,964,409, the disclosure of which is incorporated herein by reference. Each of the hose 18 and rod 15 may be provided with conventional fixing and connecting means to achieve ...

Abstract

A pressure washer is provided. The pressure washer includes a water inlet port for receiving water from a water source. A water outlet port is in fluid communication with the water inlet port. A pump is in fluid communication with the water inlet port and the water outlet port for pressurizing the water received through the water inlet port and pumping the pressurized water through the water outlet port. An internal combustion engine powers the pump. A heat transfer unit is interposed between and in fluid communication with the water inlet port and the water outlet port. The heat transfer unit receives exhaust gas from the internal combustion engine and uses the exhaust gas to heat the water as it travels between the water inlet port and the water outlet port.

Description

technical field [0001] The present invention relates generally to pressure washers and, more particularly, to gasoline powered pressure washers commonly used in household powered spraying and washing applications. Background technique [0002] Gasoline-powered pressure washers have become increasingly popular for household cleaning applications, including cleaning decks, patios, siding, cars, and more. Such pressure washers are currently economically manufactured and available to consumers at most hardware and home improvement retail outlets. Such gasoline powered pressure washers basically consist of a movable cart or table, a water pump, an internal combustion engine to power the pump, and a spray wand and nozzle assembly. After connecting the shared garden hose between the home's outlet and inlet ports to the pressure washer's pump, operate the pressure washer to generate high pressure liquid discharges up to 1000 psi and even higher for power spray applications. Chemic...
