VENTILATOR FOR REFRIGERATORS.
Application filed November My invention relates to a device for ventilating the interior of refrigerators and has for its main and particular object to pro vide a ventilator which will effectively and n automatically remove moisture and odors from the air in the refrigerator to which it is attached.
A further object is to so construct the ventilator that it will be sanitary, vermin proof,
it) easy to install, pleasing in appearance, simple in construction and comparatively inexpensive to manufa ture.-
These and VariOUs other objects and advantages will be clearly understood from 1 the following description and from the accompanying drawing of a preferred embodiment of my invention, but it will be noted that various modifications might be made without departing from the scope of the invention.
Fig. 1 is a side elevation of the ventilator, showing it attached in the wall. of a refrigerator.
Fig. 2 is a cross-sectional, side view of the ventilator.
Fig. 3 is a rear view of Fig. 1.
Fig. 4: is a front view of Fig. 1.
Referring now to all the views, simultaneously, 5 represents the wall of the re- 0 frigerator, 6 the front plate and 7 the rear dome of the ventilator.
The dome 7, which is bell shaped, is provided with a rearwardly extending circular tube 8. The dome 7 and the tube 8 are preferably made in one piece and provided, at
the dome end, with a disc 9 securely fastened therein and forming a part thereof. The other end of the tube is provided with a plurality of slits 10, thus forming the lugs 11 as plainly shown on Fig. 4L.
The dome is provided with a plurality of air holes 12, equally spaced around its periphery. The tube is likewise provided with an equal number of air holes 13 and the disc 9 is provide-d with an air hole 14:. In the drawing, four air holes are shown in both the dome and in the tube but any suitable number may be employed. However, I find that the best result is obtained when the combined area of the air holes in the dome and disc bear a fixed relation to the cross-sectional area of the tube 8. I find 12. 1925. Serial No. 58,648.
this ratio to be 2 to 7, the larger area being that of the tube. The front plate 6 is provided with a circular opening 15 aligning, Fa when the device is assembled, with the opening in the tube.
The ventilator is attached by drilling a hole of suitable size, in any desired place, through the door or wall of the refrigerator. 6 The tube. 8 is inserted in this hole so that the dome 7 is in the interior of the refrigerator, after which, the lugs 11 are bent over as shown in Fig. 4. A wire-mesh screen 16 is placed over the opening and finally 05 the front plate is nailed on, by means of the small nails 17, its center opening in alignment with the tube. While the slits 1.0 allow for variation in the thickness of the door or wall of the refrigerator, any 7 other suitable adjusting means may be em ployed.
Due to the air in the refrigerator being heavier than the outer air, the ventilator allows a portion of the confined air to es-. cape, carrying with it odors and excess moisture.
The escape of this air destroys the equilibrium and causes air from the outside to flow into therefrigerator thus causing a slight pulsation, suflicient however, to effectively ventilate the interior when the above mentioned ratio between the openings is employed.
Having thus described my invention, what I claim as new and wish to protect by Let ters Patent is:
1. In a ventilator of the class described;
a tubular member leading from the interior to the exterior of a refrigerator; the inner end of said, tubular member provided with a closure disc having an orifice; a plurality of orifices provided in the inner end of the tubular member; a perforated dome extending from the inner end of the tubular memher and abutting against the wall of the refrigerator so as to form an air chamber around the end of the tubular member; and means for attaching the ventilator to the refrigerator.
2. In a ventilator of the class described;
a tubular member leading from the interior to the exterior of a refrigerator; the inner end of said tubular member provided with a closure disc having an orifice; a plurality of orifices provided in the inner end of the tubular member; a dome, provided With orifices, extending from the inner end of the tubular member and abutting against the wall of the refrigerator so as to form an air chamber around the end of the tubular member; the combined area of all of said orifices in the closure disc and dome being equal to tWo-sevent-hs of the cross-sectional area of the tubular member; and means for attaching the ventilator to the refrigerator.
