3 Claims. 1
This invention relates to a novel device for removing unpleasant Odors from toilets and other such enclosed areas.
An object of the present invention is to provide novel'means for drawing air from a room, cleaning or deodorizing the same, and re-circulati'ng it back to said 'room.
Another object ofthe invention is toprovide air deodorizing means that can be switched on and left to complete its cycle of operation for a predetermined time period without the need for switching the same off.
A further object of the invention is to provide means, as indicated, that can, optionally, be placed in continuous operation.
A still further object of the invention is to provide novel'switch-operated means, in a device of the character referred to, that requires only finger touch pressure on a starter button to institute the cycle of operation of said device.
The invention also has for its objects to provide such means that are positive in operation, convenient in use, easily installed in a working position and easily disconnected therefrom, e'conomical of manufacture, relatively simple, and of general-superiority and serviceability.
The invention also comprises novel details of construction and novel combinations and arrangemen-ts of parts, whichwill more fully appear in the course of the following description. However, the drawings-merely show and the following description merely describes one embodiment of the present inventionywhich is given by way of illustration or example only.
In the drawings, like reference-characters designate similar parts in the several views.
Fig. l is a frontelevational view showing the present 'device as installed in'a wall of the room beingserved by said device.
Fig. "2 is a side elevational View thereof, a portion of the wall being in section.
Fig. 3 is a vertical sectional View as taken on line 33 of Fig. 1.
Fig. lis 'an electrical wiring diagram of the instrumentalities of said device.
While shown as'a'wall installed unit, the present device may beconstructed as a portable unit that can beconnected' to an electric outlet in any room or area theair of'which requires cleaning or deodoriliing It will be seen from the following description that the device is adapted for use as an air conditioning unit since the same circulates the air of a room whether or not deodorant is employed therein.
The illustrated device comprises, generally, a front panel that supports a base ll, an aircirculating unit 12, a motor [3 for driving said unit, a double pole-double-throw switch '14, cycle-timing means embodying an electrically operated timer l5 anda mercury switch lacontrolled thereby, a push button switch IT for instituting the operation of the cycle-timing means, and suitable tell-tales ISand {'9 advising whether said device is in circuit for continuous operation or for periodic operation as controlled by switches M'and l1.
According to the invention, the air-circulating unit comprises a fan or blower 29 that is provided with an air inletzl which preferably extends through panel I'll to be accessible from the room side of the device. Inlet 2| is shown as an upwardly angularly directed tube or pipe that is adapted to hold a quantity of material such as deodorant crystals 22. A suitable screen across the inlet to the blower 20 prevents the crystals from "entering the blower housing. Access to tube 2| is'afforded through a closure cap 23 that is provided with a foraminous face 24 olfering minimum interference to air intake. Said cap may be -hinged, as shown.
A variation of the inlet 2! may comprise a branched arrangement one branch only containing crystals.
A suitable valve isprovided for efiecting selection'of which branch is open to the blower. v
The motor is preferably of the air cooled type, since, under certain conditions, the'same may be in continuousoperation. Accordingly, a-fan 25 is provided to-cool the same.
Switch [4 is indicated as a toggle switch adapted to have one of two positions. The timer I5 is a unit comprising a low-geared motor having suitable reduction-gearing providing fora slow speed of rotation of its output shaft 26. On said shaft is mounted a disc 21 in 't'he periphery of which is formed a single'V-shape'dnotch28. A pivoted arm 29 'has a dog end 39 normally residing in said notch, 'the arm being "generally horizontal until 'rotationof disc '21 causes the walls of the notch to displace the dog end '30 upwardly arid thereby tilt saidar'm. The mercury switch 16 is carried by the arm, is open when the arm is horizontal, and closed when tilted upon tilting of the arm.
Switch I1 is of the two point make type and always seeks an open position. A binding post circuit for the above-named instrumentalities is simplified. Said circuit will be described in detal in the course of the following description of the operation of the device.
With switch 14 thrown to contact terminals 32 and 33 thereof, current will flow from line wire 34, through motor 13 and its circuit wires 35 and 36 to the opposite line wire 31. Simultaneously, tell-tale l B will be illuminated by a circuit comprising lines 34, 38, 39, 40 and 31. Thus, the motor will be in continuous operation and tell-tale l8 lit apprising of the same.
With switch 14 thrown to contact terminal 4|, the circuit through motor 13 is closed only to binding post 3|, said circuit comprising lines 34, 35 and 42. The circuits through the timer l5 and through tell-tale 19 to said binding post are independent of switch [4. The timer circuit comprises lines 34 and 43, and the tell-tale lamp circuit comprises lines 34 and 44.
When switch I! is pressed, the circuits through motor I3, timer l5 and tell-tale l9 are closed by connecting binding post 3| with lines 40 and 31. The motor will start and tell-tale 19 will light up. Simultaneously, timer will start up instituting rotation of disc 21 and effecting tilting and, thereby, closing of mercury switch 16. Now, push-button switch I! may be released since the mentioned circuits are maintained through the mercury switch from binding post 3|, through lines '45, 46 and 31. The dog end 30 of arm 29 will ride the periphery of disc 27, holding switch 16 closed. When said dog end again falls into notch 28, said switch 16 will automatically open and, thereby, open the circuits through the motor, timer and tell-tale l9.
It will be seen that a person need only press and immediately release push-button I! to institute the cycle of operation, and may leave the room which is served by the device, with assurance that, after a prescribed period, the operation will shut 011.
The blower 12, of course, is provided with an outlet 41 and panel I0 with louvres 48 aligned with said outlet for returning the deodorized air from the room or area from which the same is drawn by the blower.
While the invention that has been illustrated and described is now regarded as the preferred embodiment, the construction is, of course, subject to modifications without departing from the spirit and scope of the invention. It is therefore not desired to restrict the invention to the particular form of construction illustrated and described, but to cover all modifications that may fall within the scope of the appended claims.
Having thus described the invention, what is claimed and desired to be secured by Letters Patent is:
