Additionally, a storage device is also provided on the pressure washer to store cleaning fluids, water bottles, or any other items which are handy to keep with the pressure washer.
Description
PRESSURE WASHER WITH REMOTE ENGINE CONTROL
Field Of'The Invention The present invention relates to pressure washers, specifically to a pressure washer with a remote engine control.
Background Information Pressure washers are well known in the art and have become-very useful whenever a stronger stream of water is needed (i.e., cleaning a car, road, vinyl siding of a house, etc.) Using a pump powered by an engine, pressure washers pressurize the water to cause the water to exit the pressure washer spray gun nozzle at a greater pressure for a given flow rate than a regular garden hose nozzle. Typically, pressure washers include an engine, pump, spray gun, hose and set of connectors for the water to enter and exit.
Since the pressure of the water exiting the pressure washer spray nozzle is directly related to the speed at which the engine actuates the pump, the user can control the pressure at a given flow rate of the exiting water by controlling the speed of the engine (i.e., the throttle). However, in current pressure washer systems, there is either no engine control (i.e., the pressure is fixed) or the engine control is located on the engine itself. Thus, the location of the engine control may be inconvenient, for example, when the height of the engine is very low relative to the height of the user.
Additionally, while some pressure washers have hooks to hold water bottles, towels, or cleaning fluid bottles, current pressure washers do not have any removable storage device for storing cleaning fluids or extra supplies.
Summary Of The Invention In an exemplary embodiment, the present invention provides a pressure washer with a remote engine control. Instead of the engine control being located on the engine itself, the engine control is located on the control panel of the pressure washer.
Therefore, the user can conveniently control the speed of the engine, and thus, the pressure for a given flow rate of the water exiting the spray gun nozzle without always having to bend down to the engine.
Additionally, in an exemplary embodiment, the present invention also provides for a storage device to store cleaning fluids, water bottles, tools or any other items which are handy to keep with the pressure washer.

The interchangeable tips 21 may be placed at the end of first nozzle 23 to vary the type of spray (e.g., narrow, wide, streamline, chemical injection, etc.) exiting the first nozzle 23. First nozzle 23 can be different from second nozzle 22 in the method of spraying, such as, for example. in spraying water in a rotary fashion. When not in use, the spray wand 6 may be stored on the wand hanger 24 which is attached to the side of frame 2 as shown in Figures l and 3.
There is also provided in the exemplary embodiment two hose hangers 25 on the rear of I S the control panel 9 to wrap the high pressure hose 19 around when it is not in use.
There is provided in the exemplary embodiment shown in Figures I-3 a storage device (e.g., storage basket I 1) for storing cleaning fluids or for keeping any useful items (towel, water, tools, etc.) with the pressure washer. The rear location of the storage basket 1 I in the exemplary embodiment also makes it convenient to connect, for example, the siphon tube 30 from the pump 5 to a cleaning bottle sitting on the storage basket 11. The siphon tube 30 allows the pump S to drawl cleanser into the pump S to mix with water from inlet 7 to form a mild cleaning solution to better remove dirt, etc.

The footings 12 and the wheels 13 may be made of rubber or any other durable material conventionally used in the art.
Unlike existing pressure washers, the engine control (e.g., throttle control 1 S) is not located on the engine 4. Rather, the engine or throttle control 1 S is remotely located on the control panel 9 which is attached to the frame 2 as shown in the exemplary embodiments Figures 1 and 2. Here, the throttle control 15 includes, for example, a throttle arm 34 connected to a knob 33 on one end and to a cable 16 on the other end. The cable 16 is also connected to the engine 4 and moves in the same direction as the throttle arm 34 in order to control the speed of the engine 4. Hence, the throttle control 15 allows the user to control the engine remotely (i.e.. at a distance from the engine). The throttle control 15 can be any other remote control device known in the art.
In addition to throttle control I 5, the control panel 9 in the exemplary embodiment shown in Figure I also includes a plurality of cavities 20 to hold, for example, interchangeable tips 21 or a second nozzle 22 for the spray wand 6. When in use, the spray wand 6 is attached to the high pressure hose 19 on one end and to a first nozzle 23 on the other. The interchangeable tips 21 may be placed at the end of first nozzle 23 to vary the type of spray (e.g., narrow, wide, streamline, chemical injection, etc.) exiting the first nozzle 23. First nozzle 23 can be different from second nozzle 22 in the method of spraying, such as, for example. in spraying water in a rotary fashion. When not in use, the spray wand 6 may be stored on the wand hanger 24 which is attached to the side of frame 2 as shown in Figures l and 3.
There is also provided in the exemplary embodiment two hose hangers 25 on the rear of I S the control panel 9 to wrap the high pressure hose 19 around when it is not in use.
There is provided in the exemplary embodiment shown in Figures I-3 a storage device (e.g., storage basket I 1) for storing cleaning fluids or for keeping any useful items (towel, water, tools, etc.) with the pressure washer. The rear location of the storage basket 1 I in the exemplary embodiment also makes it convenient to connect, for example, the siphon tube 30 from the pump 5 to a cleaning bottle sitting on the storage basket 11. The siphon tube 30 allows the pump S to drawl cleanser into the pump S to mix with water from inlet 7 to form a mild cleaning solution to better remove dirt, etc.
The storage basket 11 may be connected by any means known in the art, such as by inserting the ends of the storage basket 11 into brackets or holes (not shown) located inside the side panels 10. The storage basket 11 may be of a wire design or any other design known in the art. Any other storage device or configuration known in the art also can be used.
The storage basket I 1 may be removable to make the pressure washer 1 more compact, for example, for storage.

When the user seeks to store away the pressure washer 1, the user may simply unscrew the coupling members 18 and place the removable handle 17 onto the storage basket I 1.
In order to operate the pressure washer 1 of the present invention, the user would first attach, for example, a garden hose 26 to the inlet 7 located on one side panel 10 as shown in Figure 1. The inlet 7 may be connected to a pump inlet 28 by, for example, a tube 27 as shown in Figure 1. A tube 27 also may be used to connect the pump outlet 29 to the outlet 8 of side panel 10. The outlet 8 is connected, for example, to a high pressure hose 19 which is then connected to one end of the spray wand 6. To start the water flowing into the pressure washer 1, the user only need to turn on the water faucet (not shown) connected to the garden hose 26. In the exemplary embodiment, the pressure from the water faucet is enough to push the water though inlet 7, into pump S, out through outlet 8, into the high pressure hose 19, and out of spray wand 6, although the water pressure in this circumstance does not vary significantly from the pressure of the water faucet.
The storage basket I 1 may be removable to make the pressure washer 1 more compact, for example, for storage.
To further help keep the pressure washer 1 compact, there also may be provided in an exemplary embodiment a removable handle 17 which is attached to the top ends of frame 2 as shown in Figure 1. The removable handle 17 may have, as shown in Figure 1, coupling members I 8 or collars which are threaded to couple with the threaded top ends of frame 2.
When the user seeks to store away the pressure washer 1, the user may simply unscrew the coupling members 18 and place the removable handle 17 onto the storage basket I 1.
In order to operate the pressure washer 1 of the present invention, the user would first attach, for example, a garden hose 26 to the inlet 7 located on one side panel 10 as shown in Figure 1. The inlet 7 may be connected to a pump inlet 28 by, for example, a tube 27 as shown in Figure 1. A tube 27 also may be used to connect the pump outlet 29 to the outlet 8 of side panel 10. The outlet 8 is connected, for example, to a high pressure hose 19 which is then connected to one end of the spray wand 6. To start the water flowing into the pressure washer 1, the user only need to turn on the water faucet (not shown) connected to the garden hose 26. In the exemplary embodiment, the pressure from the water faucet is enough to push the water though inlet 7, into pump S, out through outlet 8, into the high pressure hose 19, and out of spray wand 6, although the water pressure in this circumstance does not vary significantly from the pressure of the water faucet.
When the user desires a stronger stream of water, the user may then turn on the engine -1 by pulling on a starter rope, turning a key or any other starter known in the art. The engine 4 will then actuate pump 5 which in turn will draw in water from inlet 7 at a faster rate, pressurize the water inside the pump, and force it through outlet 8, high pressure hose 19 and out of spray wand S 6 at a greater pressure for a given flow rate. Additionally, the pump ~ may draw in some cleanser stored on storage basket 11 through the siphon tube 30 to form a mild cleaning solution if the user so desires.
To create an even stronger stream of water, the user simply only need to increase the speed of the engine by pushing throttle control 15 in the proper direction.
Unlike the previous pressure washers, there is no need to make any adjustment directly on the engine itself nor does the user need to bend down to the engine to make any adjustments.
