In order to address the above problem, the invention provides a kind of spray booth, the suction air-flow that utilizes scavenger fan to form, coating cloud is sucked from the suction inlet of being located at the spray booth front lower, and in its suction gas channel, set washing spray nozzle, handle to carry out coating cloud, and cleaning gas tream discharged to the outside by scavenger fan, it is characterized in that, in described suction gas channel, be provided with suck gas channel with towards the separated other wall of the barricade of spray booth, utilize this wall to form the passage of rear portion inclination downwards, and the described nozzle that configuration is sprayed along the direction of the passage of this inclination, and forming the channel bends make this inclination and connected channel part, this channel part is along the direction configuration of tilting with respect to the direction of the suction inlet that is located at described front lower.
Such structure makes the injection sound of spray not directly towards peristome, so the sound that produces conflicts with the wall that forms wind-tunnel, the decay back passes to spray booth from peristome.The part that is equipped with noise-producing source is the inclined plane, so noise does not directly pass to the outside.
And, the injection direction of shower water is to make wide-angle with middle mind-set air-flow rightabout to spray, although conflict with the wall in oblique the place ahead, the wall that tilts separates formation with the wall (water stream board) towards spray booth, so same as described above being unlikely of the conflict sound of shower water directly is passed to peristome.Because of the extremely wind-tunnel bending of aforementioned peristome of gas channel, so its effect is better from tilting.
In addition, for the noise of the scavenger fan of the air-breathing generation of spray sound one cause, in the front of suction inlet barricade is set, make around it and stay circuitous passage, the sound that makes scavenger fan is not directly to the peristome transmission of spray booth.Even for noise by barricade, be equipped with aforementioned bending channel and also can reduce gradually, can reduce noise greatly from peristome.
