Title:
IMPROVED POWER WASHER WITH PULSING BOOST POWER MODE
Document Type and Number:
WIPO Patent Application WO/2017/096740
Kind Code:
A1
Abstract:
An electric power washer (10) contains a main body (12), a hose (18), a handle (24), and a control circuit(32).The main body(12) contains a pump(14) and an electric power source operatively-connected to the pump(14). The hose (18) contains a first end (20) that is fluidly-connected to the pump and a second end (22) fluidly-connected to the handle (24). The handle (24) has a button (26) operatively-connected to the control circuit (32). The control circuit(32) is operatively-connected to both the pump(14) and the electric source(16,16',40). The control circuit (32) controls the output of the pump (14). The control circuit (32) contains a timer (36) as well. The control circuit (32) permits the pump (14) to normally operate at up to 100% normal power. However, when the button (26) is activated, the control circuit (32) permits the pump (14) to operate at a boost power mode of from about 103% normal power to about 300% normal power. The control circuit (32) intermittently pulses the boost power mode. The control circuit (32) terminates the boost power mode after a predetermined period of time or when the button (26) is no longer activated whichever is shorter. A method of boosting the power of a pump on a power washer is also described. The electric power washer allows the user greater control, and also reduces the change of damage to the battery, the pump, and/or the internal mechanisms of the power washer.
