AIR IMPROVEMENT DEVICE Filed July 21, 1954 Patented Apr. 6, 1937 UNITED STATES PATENT OFFICE AIR-IMPROVEMENT DEVICE Application July 21, 1934, Serial No. 736,423 In- Germany December 27, 1933.
4 Claims.
The invention concerns an air improvement device with a casing, containing a ventilator and a device with disinfecting and purifying substances, over which the air is led. ,The known devices of this kind show the disadvantage that they are too complicated in construction and suck up too small a quantity of air which has to be enrichened with disinfecting substance, Frequently, in these cases, the leading of the sucked in air is such that .a part of it does not even come into touch with the enrichening device.
Owing to the fact that the channels, through which the air is led are of too small a diameter,
a comparatively large amount of driving power for driving the ventilatbr is needed .even if small quantities of air are to be driven through the device.
It is the object of this invention to avoid these disadvantages, and to create an air-improvement device, the air way of which is as short as possible, whilst the driving power is as low as possible, and large quantities of-air are sucked through per time unit. This purpose is achieved by the fact that theventilator 'is arranged in close proximity to the front inlet-opening of the casing in a chamber, which is closed in at the rear side at the top and at the sides, from which channels lead from the bottom towards the chamber for the cleaning device, which is provided with outlet openings at the sides.
The drawing shows a working example of the device which has been made the subject of this application. It shows in:
Fig. 1 a front view of the device Fig. 2 a section to the line IIII of Fig. 3,
Fig. 3 the device in cross-section to the line IIIIII of Fig. 1.
The ventilating 'contrivance of the air improvement device consists essentially of an air propeller a and a driving motor b. The outer .casing is fitted preferably with a circular shaped inlet opening c in front, which is covered by a frame it with a cylindrical rib e. Over the frame d a gauze or other tissue is stretched, which does not offer too great a resistance to the air. The air propeller a is enveloped by a casing in such distance from the rotating propeller and which only on the bottom is provided with openings orachannels p, q, leading to the chamber lying underneath which is intended for the air improvement -device consisting of the case is and the wicks g. The upper part of the rear wall 122 of the ventilating chamber is bulged or inclined towards the front, so that the propeller chamber extends towards the bottom. The
vertical channels 2), q are separated from each other by a wall 11. By means of the casing of the air propeller any stagnation of air within the casing as well as the forming of a dead space where interfering whirls of air may collect, are 5 prevented. At ,f, h, side openings have been pro vided, which are closed by flaps or similar means, which can also be covered by some sort of tissue etc. Through these openings, the air, which has been sucked in by .the propeller a through the 10 openings c,and is then projected onto the wicks g leaves the casing. The case k for the wicks y is filled with the respective enrichening material as essences, e'theric oils, etc., and can be taken out at the side of the apparatus by means of a 15 handle i, when the flap l with the side opening I is opened.
The motor 17 rests upon a pedestal or is similarly arranged and should preferably be fastened to the back wall 0 of the casing together with 20 the air propeller .and its casing. The said back wall 0 can be easily taken oil. The casing of the air propeller a shows by the forcible guid- V ance of the air the advantages that any ingredients mixed with the air as e. g. dust, smoke par- 2 ticles, etc., are projected onto the wicks, and adhere to the same. The working example shown and described'can, in accordance with the requirements of special cases in practice, be made subject to numerous alterations, without thereby leaving the scope of the invention. It is an essential feature of the invention that the air is led through the contrivance on the shortest possible way and with the least possible resistance. and is brought into the closest touch with the 35 wicks as well as with the purifying; liquids con-. tained thereon.
Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be'performed, I de- 40 clare that what I claim is:-
1. In air conditioning device, a casing with inlet and outlet openings for the air, a driving motor and a fan being driven by-said motor and arranged close to the inlet opening at the front of said casing. a chamber for said fan, being closed at the rear andat the sides, an air disinfecting and purifying device, a chamber for said purifying device close to said fan chamber, and connected with this chamber by openings in the underside of said fan chamber, the outlet openings being in the side walls of the chamber for said purifying device, all parts being arranged in such a manner that the air is sucked up in axial direction of said fan and pressed vertically n the air purifying device substantially by centrifugal force of said fan for being driven out through the lateral outlet openings with the shortest way possible within the conditioning de- 5 vice and after passing above said purifying device with change of flowing direction.
2. In air conditioning device, a casing with inlet and outlet openings for the air, a driving motor and a fan being driven by said motor. and arranged close to the inlet openings at the front of said casing, a chamber for said fan with walls close to the moving space of said fan, an air disinfecting and purifying device, a chamber for said air purifying device close to said fan chamber, said fan chamber having openings in its underside for connecting it with said air *purifying chamber, said outlet openings for the air being arranged in the side walls of said purifying chamber, said purifying device being arranged vertically under said fan for pressing the air by centrifugal force of said fan upon the purifying device and driving it out by the shortest way possible within said conditioning device after passing close to said purifying device with a right angular change of its flowing direction.
3. In an air conditioning device, a casing with inlet and outlet openings for the air, a driving motor and a fan being driven by said motor and arranged close to the inlet opening at the front of said casing, a chamber for said fan, being closed at the rear end at the sides, an air' disintherefrom, a chamber for said purifying device close to said-fan chamber in communication with the underside of said fan chamber, said .putlet openings being arranged in the side walls of the chamber for said purifying device.
a 4. In an air conditioning device, a casing with inlet and outlet openings for the air, a driving motor and a fan being driven by said motor and arranged close to the inlet opening at the front. of said casing, a chamber for said fan with walls close to the moving space of said fan, an air disinfecting and purifying device, a chamber for said air purifying device close to said fan chamber, said fan chamber having openings at the underside thereof, for connecting it with said air purifying chamber, said air outlet openings being arranged in the side walls of said purifying chamher and serving also as passages for the slidable removal of said purifying tray, said purifying device being arranged vertically under said fan for pressing the air by centrifugal force of the fan upon the purifying device and driving the air out by the shortest way possible within said conditioning device after passing close to said purifying device with a right angular change of the flowing direction.
