Claims. 1
This invention relate'sto improvements in a portable sterilizing apparatus adapted for elimination of bacteria from the atmosphere confined within a room of a' dwelling orother enclosure.
It is known that subjection of bacteria to the effect of ultra-violet rays, emitted from lamps of a character producing such rays, results in destruction of the life of bacteria; And it is also known that ultra-violet rays emitted from any source is highly detrimental to human vision.
An object of the instant invention is to afford an apparatus that is readily installed or moved about from one place to another in a room or other enclosure and through which the atmosphere is continuously circulated and subjected to ultra-violet rays cated in'the apparatus.
Another object of the invention is to provide in connection with the apparatus adjustable blinds or deflectors by which the rays emitted. from the lamps are restricted to planes parallel with the floor and ceiling of the room out of normal range of vision of occupants of the'room thus to obviate baneful eiiects of the rays.
I And a further object of the invention is to pro? vide mans' for subjecting instruments or other articles to sterilization in the apparatus by the effects of the emitted ultra-violet rays during circulation of the atmosphere passing therethrough.
Other objects and advantages of the invention appear in the'followin' description.
An illustrative embodiment of the 1 invention is shown in the accompanying drawings, in,
which- Fig. 1 is' a front elevational view of an appa ratus 'e'mbodying the invention, portions thereof being shown in section to expose the interior thereof; 7
Fig. 2 is a top plan view of the apparatus, partially broken away; t
Fig. 3 is a transverse'section of Fig. 1 on the line ;1::r thereof; v
Fig. em a top plan View of the base for the apparatus including a fragmentary arrangement of lamps overlyin the base and supports therefor which are shown in section; and.
Fig. 5 is a detail horizontal section on the line y-y of Fig. 1 showing one of the instrument supports secured to a door.
Figs. 2, 4 and 5 are drawn to an increased scale.
The illustrative embodiment of the invention consists of an upright flue, indicated generally by A, having front and rear walls 6 and I and side walls 8 and 9 supported by corresponding emitted from suitable lampslo corner posts I 0 at their junctures. The lower ends of the posts rest upon a pyramidal base it and extend downwardly beyond the bottom of the front, back and side walls, thus to afford an inlet opening 12 for air. The upper endsof saidv posts have mounted thereon an inverted pyramidal lid is and extend upwardly beyond the tops of said walls to afiord an opening M for the outlet of air. v
. The upper portion of the flue A has hinged doors l 5 in its several walls, the doors being pro: vided with inwardly extending air defiectorslfi that tend to collect dust from the atmosphere passing through the flue, the dust being subsequently removed, occasionally by opening of the doors and wiping the deflectors. o
The midportion of the flue has another hinged door ll in one of the side walls 9 thereof, on the inner side ofwhich are disposed one or more clips It for the support of instruments or other articles (not shown) to be sterilized A horizontally sliding shelf is is mounted on cleats 20 in the flue, to which shelf is secured amotor-driven fan 21, there being an opening"?! in the shelf to permit passage of air therethrough driven by the fan. v
A series of ultra-violet ray lamps 23 are mounted on the extending ends of the posts 18 below the walls of the flue and are disposed in the plane of the air inlet opening I2 so that the rays emitted] from the lamps radiate outwardly throughsaid inlet opening and upwardly into-the flue. On the lower portion of the flue about the exterior thereof is arranged a vertically adjustable blind .25 bymeans of which the raysirom the lamps, radiated outwardly through the air inlet l2, are restricted approximately to the plane of'the inlet opening and parallel with the floor upon which the apparatus is placed, the floor not beingshown. V I v Another series of ultra-violetray lamps 24 are likewise mounted all the upwardly extending-ends oFthe' posts: Ill, above the tops ofthe flue'wall s, and are disposed in the plane of the air outlet opening It, so that the rays emitted from the lamps 24 radiate outwardly through the air outlet opening l4, and downwardly into the flue. On the upper portion of the flue, about the exterior thereof, is arranged another vertically adjustable blind 25 by means of which the rays from the lamps 24 radiate outwardly through the outlet opening M, are restricted approximately to the plane of the outlet opening, and parallel with the ceiling of the room in which the apparatus is located.
All of the lamps and the motor for the fan are energized by current from a suitable source of energy through ordinary conductors as in the usual manner (not shown).
Operation In utilizing the invention, the apparatus is stood upright on its base upon the floor of a room with its upper end disposed adjacent the ceiling. Suitable connections then are made for electrically energizing the lamps and the motor for the fan ordinarily by use of a plug-in extension cord. When the electric current is turned on, the atmosphere in the room is drawn in through the inlet opening l2 into the fine and forced upwardly therethrough and expelled through the outlet opening 14, the lamps 23 and 24 emit ultra-violet rays outwardly through the air inlet 12 and the outlet opening l4, and directly into the flue. The blinds 25 and 25' are adjusted on the flue so the rays radiated outwardly through the air inlet and outlet are confined closely to the floor and ceiling of the room. Opening of the door I! permits the shelf is together with the motor fan mounted thereon to be removed when occasion arises, and dust accumulated in the upper portion of the flue is readily removable upon opening of the doors 15.
By continuous operation of the apparatus the atmosphere within the room is cleansed of air borne dust, bacteria, and the like, thus improving the condition of the atmosphere within the room. Variations from the particular construction above disclosed may be restored to by the exer-'- cise of skill in the art, without departure from the spirit or scope of the invention.
