Device for Supply of Breathing Air to a Breathing Air Region

Abstract

A device for supplying breathing air to a breathing air region has an air purification unit with filter unit and blower unit. First areal outflow regions with air outlet openings and having a first surface area are provided. The air purification unit supplies breathing air to the first areal outflow regions and the breathing air flows out in an outflow direction. Areal boundary devices with a second surface area are provided. The areal boundary devices are arranged opposite the first areal outflow regions such that each first areal outflow region has one of the areal boundary devices positioned opposite thereto at an angle of less than 10°. The second surface area of the areal boundary device corresponds at least to the first surface area of the first areal outflow region. The breathing air region is located between the areal boundary device and the first areal outflow region.

         2 . The device according to  claim 1 , wherein an outflow velocity of the purified breathing air from the one or more first area outflow regions is greater than a flow velocity of the purified breathing air in the breathing air region. 
     
     
         3 . The device according to  claim 2 , wherein, when the device is operating in an environment of stationary ambient air, the flow velocity reached in the breathing air region due to the purified breathing air flowing out of the one or more first areal outflow regions amounts to less than 0.1 m/s. 
     
     
         4 . The device according to  claim 2 , wherein the outflow velocity of the purified breathing air amounts to at least 0.2 m/s. 
     
     
         5 . The device according to  claim 1 , wherein the one or more areal boundary devices are arranged perpendicular to the outflow direction from the one or more first areal outflow regions. 
     
     
         6 . The device according to  claim 1 , wherein the first areal outflow region and the areal boundary region associated therewith and arranged opposite thereto are arranged mirror symmetrical to a symmetry plane relative to each other, wherein the symmetry plan divides the breathing air region and extends transverse to the outflow direction. 
     
     
         7 . The device according to  claim 1 , wherein at least one of the areal boundary devices is a second areal outflow region. 
     
     
         8 . The device according to  claim 7 , wherein the surface area of the first areal outflow region and the surface area of the second areal outflow region are identical. 
     
     
         9 . The device according to  claim 7 , wherein the first and second areal outflow regions are congruent relative to each other. 
     
     
         10 . The device according to  claim 7 , wherein the first areal outflow regions each have a congruently embodied second areal outflow region positioned opposite thereto. 
     
     
         11 . The device according to  claim 1 , wherein a ratio of a square of a distance between the first areal outflow region and the areal boundary device associated therewith, measured in centimeters, relative to a surface area of the first areal outflow region measured in cm 2  amounts to approximately 5 to approximately 25. 
     
     
         12 . The device according to  claim 1 , wherein the first areal outflow region has a surface area of at least 400 cm 2 . 
     
     
         13 . The device according to  claim 1 , wherein a ratio of a distance between the first areal outlet region and the areal boundary device associated therewith, measured in centimeters, and an outflow velocity of the purified breathing air from the first areal outlet region, measured in centimeters per second, amounts to at least 1.0. 
     
     
         14 . The device according to  claim 1 , wherein at least one of the first areal outflow regions is flat. 
     
     
         15 . The device according to  claim 1 , wherein at least one of the first areal outflow regions comprises a multitude of the air outlet openings. 
     
     
         16 . The device according to  claim 15 , wherein the multitude of the air outlet openings are embodied in a fabric.
