Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a high-pressure cleaner having a leakage detection function, and more particularly, Pressure washing machine.
In general, a high pressure washer is a cleaning device that supplies water used for cleaning using a pressure pump at a high pressure. In recent years, a pressure switch is installed on an internal pipe to automatically drive the pressure pump when the pressure inside the pipe decreases, The pressure pump was automatically stopped so that the appropriate high-pressure water was continuously supplied.
However, when a leak is generated on the supply line of the pressure pump or the water, the pressure pump is automatically driven while the internal pressure is decreased. When the pressure is increased by driving the pressure pump, the pressure pump is stopped The pressure pump is continuously driven to cause damage to the motor due to the overload, and power consumption is increased due to unnecessary operation of the pressure pump regardless of the cleaning operation.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide an apparatus and a method for automatically controlling a pressure pump according to an on / off operation signal of a pressure switch, And a leakage detection function capable of preventing the pressure pump from being damaged or consuming unnecessary power by detecting the leakage when the leaked water is generated and by emergency stopping the repetitive driving of the pressure pump.
According to an aspect of the present invention, there is provided a pressure pump comprising: a pressure pump (110) for driving a pump and pressurizing water introduced into a pump chamber (113) through a water inlet (111) at a predetermined pressure and discharging the water to a water supply port (112); A water delivery pipe (120) connected to the water supply port (112) and transferring water discharged at a high pressure to a rear end; A
