Description
Technical field
The present invention relates to Airshower chamber technical field, especially a kind of Airshower chamber of automatic sensing.
Background technique
Airshower chamber is a kind of indispensable for drug, vegetables, raw and cooked foods finishing and precision instrument, electronic instrument workshop
Cleaning equipment is usually mounted between toilet and non-toilet.When staff or cargo will enter clean area, pass through this
The pure air of equipment blowout, can remove the sundries such as dust entrained by staff or cargo, hair, hair crumbs, using filter
Device remove, thus effectively prevent dust, bacterium enters clean area, meet the stringent sanitary standard in work-yard, produce height
The product of quality.
In modern industrial production, Airshower chamber has become food factory, the indispensable workshop of drinking water administrative office in a factory QS, HACCP certification is set
It is standby.But the drenches effect of existing Airshower chamber suffers from wind leaching people's behavior at that time limitation on the market, such as too close to side
When wind leaching mouth or arm do not lift, wind leaching is not thorough, and there are many places dedusting dead angles, and only spray is arranged in two sides in existing Airshower chamber
The leaching of mouth wind, the personnel of often requiring that enter after Airshower chamber autorotation to ensure comprehensive wind leaching, but not can guarantee after everyone enters
Will rotation body carry out wind leaching, cause the environment of dust free room contaminated, can not thorough dedusting, thus can be to the quality of product
Control causes very big hidden danger.
Meanwhile existing Airshower chamber generally judges whether personnel to be cleaned are in place, treat by single infrared sensing device
The accuracy in detection of clean article is lower, and regardless of personnel or article height when work, all nozzles of two sides are all together
Work, shower are relatively dispersed, and not can be effectively carried out concentration cleaning, especially when article height is lower, since the height of nozzle limits
System can not even more clean thoroughly.But if using a plurality of infrared sensing devices, since infrared sensing device enters wind from personnel
In place just always on behind leaching room, energy consumption increases, and does not meet the energy-saving and environment-friendly developing direction of today's society.
Summary of the invention
In order to overcome the disadvantages mentioned above of the prior art, the object of the present invention is to provide a kind of Airshower chamber of automatic sensing,
Using rotatable Work turning table structure, dedusting is more thorough；Optoelectronic induction dresses different with height using pressure sensor simultaneously
It sets, energy-efficient, detection accuracy is high, and wind leaching is more concentrated, and cleaning effect is good；Top is additionally provided with Chui Lin mechanism, and further expansion is clear
Clean range, dedusting are more thorough.
