2, advancing/exhaust outlet position apart from each other of low noise high pressure cleaning machine of the present invention avoids discharging the outer hot blast of jetting machine and is back to air intake passage again and comes cool motors, thus the possibility that causes motor temperature to exceed standard;
3, the air inlet position of low noise high pressure cleaning machine of the present invention is arranged on the casing rear portion; The exhaust outlet position is arranged on the bottom of shell front end; Helping doing safety IPX5 spray in the jetting machine normal operating position and the position of falling tests; Effectively avoid water to be splashed into interior, get into movement inside again, cause the possibility withstand voltage, that leakage current exceeds standard;
4, the cartridge assemblies of low noise high pressure cleaning machine of the present invention be installed in except that advance/exhaust outlet the relative interior of sealing; The airflow noise, the eddy current sound that produce when preventing jetting machine work are directly propagated outside casing; Effectively the noise of control interior reaches the purpose that noise reduces to casing external communication possibility;
When 5, low noise high pressure cleaning machine of the present invention is worked; Series-wound motor drives fan blade and rotates at a high speed; The casing extraneous air forms air-flow rapidly and flows into air intake denoising device inside; The fricative noise in suddenly big or suddenly small noise reduction air channel, flow at high speed airflow passes cross section, the part noise is absorbed by the air intake baffle blanket, effectively reduces the flow at high speed noise generated by air flow;
6, the cartridge assemblies of low noise high pressure cleaning machine of the present invention, the air intake noise reduction circle, the air-out silencing block that are provided with on its fan housing, air communication can further reduce noise generated by air flow later;
When 7, low noise high pressure cleaning machine of the present invention is worked; Swiftly flowing thermal current is discharged from fan housing air-out silencing block, and the whole surface of water pump is cooled off, and thermal current compiles through air draft noise reducing plate, air draft silencing block; Drain into outside the jetting machine; Further reduced noise, noise reduction is obvious, has improved the influence degree that NOISE ON ENVIRONMENT is polluted greatly;
8, low noise high pressure cleaning machine of the present invention is provided with two road air-out silencing blocks and air draft silencing block; Main effect is noise reduction and filtration; The carbon brush dust that is mixed in the air-flow passes through this two roads air-out silencing block and air draft silencing block; Can effectively filter out dust, guarantee to discharge the outer air clean hygiene of jetting machine, prevent to cause ambient dust to pollute;
9, low noise high pressure cleaning machine denoising device of the present invention is simple in structure, technology reasonable, realization easily.
