GERMICIDAL DEODORIZER Filed April 4, 1952- INVENTOR. TERENCE JOHN MILLS v H T'TORNEY United States Patent O "ice GERMICIDAL DEODORIZER Terence John Mills, Jamaica, N. Y.
Application April 4, 1952, Serial No. 280,695
1 Claim. (Cl. 21120) This invention relates to germicidal deodorizers, and more particularly to a combined mercury vapor germkilling ray lamp and germicide vaporizing deodorizer.
It is an object of the present invention to provide a combined ultra-violet lamp and germicide vaporizing deodorizer employing a common fan for drawing the air past the ultra-violet ray lamp thereby purifying the unclean air and immediately thereafter before it is again subjected to the surrounding space and within a confined chamber and while under the pressure of the fan, treating the ozone produced air with vaporizing liquids having triethylene glycol, so that the cleaned and germicide treated air will be taken great distances from the deodorizer and will thereby efiect dual treatment of the air to remove it of offensive odors and from the smell of ozone which has a smell objectionable to some people.
It is another object of the invention to provide a deodorizer employing a vaporing device usable in connection with ultra-violet ray lamp which can be controlled to permit more or less of the germicide to be evaporated and to thereby allow the operator to control the amount of the germicide which is dispensed into the room and wherein access can be had to the container and wick having the germicide for the purpose of making possible the easy refilling of the container and the conditioning of the wick.
It is still another object of the invention to provide a combined ultra-violet lamp and germicide deodorizer in which the lamp, the motor and fan, the germicide container and the ballast or transformer are arranged in a single container so that the air is. drawn downwardly by the fan over the lamp and forced immediately upon leaving the lamp downwardly over the vaporizing unit.
Other objects of the invention are to provide a combined ultra-violet lamp and germicide deodorizer having the above objects in mind, which is of simple construction, inexpensive to manufacture and operate, highly eflicient and effective in use, has a minimum number of parts, has a translucent crown through which the rays of the lamp may penetrate to indicate that the deodorizer is in operation and to give the same a pleasing appearance, easily installed upon a wall surface high enough to be out of the way of the occupant of the room, durable and will have long life.
For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing in which:
Figure 1 is a top perspective view of the combined ultra-violet ray lamp and germicide vapor deodorizing unit embodying the features of the present invention;
Fig. 2 is an enlarged vertical sectional view taken on line 2-2 of Fig. 1 with the deodorizer shown mounted upon a wall surface;
Fig. 3 is a perspective view of the lamp mounting within the top of the cylinder housing;
Fig. 4 is a fragmentary sectional view taken on line Patented July 17, 1956 4-4 of Fig. 2- and looking upon the top edge of the mounting bracket;
Fig. 5 is a perspective view of the finger grip support for the germicide container removed from the bottom cap to which the same is attached when mounted into the cylinder housing;
Fig. 6 is a fragmentary top perspective view of the germicide vaporizing wick and container showing the adjustable member for the wick extending laterally therefrom.
Referring now to the figures, 10 represents a cylinder housing formed of suitable material and open on both the upper and lower ends thereof. A laterally extending attaching bracket 11 is connected by its arcuate portion 12 at the side of the cylinder housing 10 and has portions 13 and 14 to which screws may be extended for securement of the deodorizer. to the wall surface. This cylinder housing is held in an upright manner on the wall so that air can be passed downwardly therethrough from the top and outwardly from the bottom.
Fitted on the top end of the cylinder housing 10 is a translucent plastic and colorful crown 17, generally circular in shape and extending outwardly from the front of the housing but cut away at the rear thereof at 16. This crown 17 also has a depending attaching portion 18 to conveniently fit within the open upper end of the cyltightened secure upwardly bent ends 25 and 26 respectively of the bracket 21 to the top of the cylinder housing. 1
On this bracket 21 there is mounted a lamp socket 26 by means of fastening screws 27. A screw 28 serves as a terminal .to which wire 29 is attached. Another wire 30 is attached to another terminal at the rear of the socket 26" to provide the other connection for the lamp bulb.
In this socket there is useda germicidal ultra-violet and ozone producing lamp v bulb 31 developed for use in room 5 parts a clean, outdoor smell to the air treated by the lamp. Any air treated with the lamp rays becomes effectively sterilized and forced draft induced by the fan delivers clean ozone bearing air into the room. Some people' can stand the smell. of the ozone while others object to it, and accordingly any use of the lamp by iself in places where the air is to be breathed by the occupants has been objectionable.
While a single lamp bulb 31 is shown, it will be understood that the two lamp bulbs would easily be mounted on the bracket 21 by employing another socket 26' and making the appropriate wire connections with an electric energizing source.
Also, mounted in the space within the attaching portion 18 of the crown 17 and in the upper end of the cylinder housing 10 and by the same bolts 19 and 20, is a fluorescent lamp ballast 32 which may be removed with the bracket, lamp and socket, and fan from the top of the housing as a complete unit. Bifurcated end portions 33 are provided on the ballast 32 for receiving the bolts 19 and 20. This ballast has wires 34 and 35 extending therefrom and connected to the power source. Cable cord 36 extends out of the housing by way of a bushing 37 and has a plug 38 by which it is attached toan ordinary wall or electric receptacle. This cord has a wire 39 connected with an electric motor 40 fixed by means of a screw 41 to the bracket 21 at hole opening-41 Fig; 3. The motor 40 drives a fan 42 that servesto draw air downwardly through the'cylinder-housing and overthe ultra-violet lamp 31- so that this air is treated by the lamp and is moved under pressure ofthefan 42 downwardly through the housing and toward and over a vaporizing unit 43 having a container 44 filled withthe liquid bearing triethylene glycol and a wick adjusting mechanism 45 from which a wick 46 extends to draw the liquid out of the container and to make it available to the lamp treatedair which is being moved downwardly through the cylinder housing 10. This lamp treated air is accordingly made a carrier for the germicide dispensed by the vaporizing unit 43 so that the germieid'e is carried by this air to locations removed from the deodorizer.
A special finger projecting; bracket 47 having finger projections 48, 49 andSO, Fig. 5, and; a handle projection 51 receives the container 44 and holds the same against displacement Within the cylinder housing. This bracket 47 has an opening 52 in the bottom thereof 'by which it is fixed by a grommet 53 to a bottom perforated cap 54 having perforations 55 andwhich is fixed to the lower end of the cylinder housing It will be noted that both the vaporizing unit and thelarnp 31 are olfset from motor 40 of the fan blade 42 so that an unimpeded induced draft from the centrally located fan blade 42 can be had. It will thus be seen that the lamp treated air is immediately treated with the liquid from the vaporizing unit so that any ozone produced will be overcome by the sweet smell of the vaporizing germicidal bearing liquid. The liquid can have any of'the wellknown fragrances, such as pine, fruit, spearmint, or-such other well known fragrances which are available.
The wick mechanism 45 has a turn shaft 56 which extends through an opening 57 in the side wall of the housing and to which there is attached'at its outer end a turn knob 58 by means of a set screw 59. With the knob 58' removed, the shaft 56 can be, easily drawn through the opening 57 and the vaporizing unit removedas the cap 54 with the vaporizing unit 43 is fixed-.to. the end of the housing or removed therefrom. It will thus be seen that the vaporizing unit iseasilyaccessible. so that the container 44 can be refilled with the vaporizing liquid.
The translucent plastic crown 17 is so shaped to. direct easily the air to the cylinderjhousing and on the lamp being energized so that light rays pass, outwardly thereof, this crown is illuminatedin a manner sothat the operation of the deodorizerwill be indicated; so as-to give the deodorizer a pleasing appearance. It should now be apparent that there has been provided a highly efiective deodorizer employing botha lamp and a vaporizing unit in a single cylinder housing and'a fan for forcibly. moving the air through the housingandjn such a manner that it is drawn downwardly over the lamp. and forced outwardly over the vaporizing unit;
While various changes may be made in the detailed construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.
A combination wall mountable ultra-violet lamp and vaporizing unit deodorizer comprising a vertically extending tubular cylindrical, housing, mounting means sccured to the outer periphery of the housing for supporting the deodorizer on a wall, a bracket extending trans versely across the top of thehousing, a crown having an outwardly flared portion and a portion projecting inwardly for engagement with the top of the housing, a lamp socket mounted intermediate the. bracket, an ultra-violet lamp disposed in the socket, an electric fan depending downwardly from the bracket, said fan positioned to induce air flow over the lamp from the top of the crown and force air to flow under pressure downwardly through the housing, a ballast in the housing in electrical connection with-the lamp socket for the lamp, means forfastening the bracket to the upper end of the housing; and serving as. well to connect the crown and the bracket to the housingwhereby upon removal of said fastening means the electric fan, the lamp socket, the ballast and the crown may: be released from the cylinder housing, an electrical circuit connectingthe electric fan, ballast and lamp socket to a current source, a removable perforated cap frictionally engaged to the lower end of the cylinder housing, a friction grip clamping bracket projecting upwardly on said cap, a. vapor deodorizing container having an adjustable wick mechanism supported on said cap and positioned by the clamping bracket, said wick mechanism having a turn shaft extending outwardly through the housing and an adjusting knob secured to the turn shaft whereby upon depletion, of a vapor deodorizing fluid in the container the cap may be readily removed to provide access to the container for refilling.
