Application May 20, 1954, Serial No. 431,118

1 Claim. c1. 4-213 The object of my invention is to produce a toilet ventilating system for connecting the toilet bowl directly with an outside exhaust ventilator, completely under power control, and operative automatically only when the toilet is in use. v

Another object is to produce an electric toilet exhaust ventilator that is simple in construction, easily and efiiciently installed and operated, and that can be manufactured at a very low cost.

The objects are attained in the. preferred form by the construction and arrangement of parts as are more fully hereinafter set forth.

Similar parts on all drawings are marked by similar numerals or letters.

Fig. 9 is a top view of the motor-fan exhaust unit as mounted within a retaining wall, showing the relative position therein, and the electric power cable connections.

In general my device is a hollow, perforated toilet seat unit hingedly mounted on adjustable tubular support units opening therein and also connected to an electric power fan exhause system mounted within an adjacent wall recess leading to an outdoor ventilator.

I will now describe more fully the detail construction of my device, referring to the drawings and the marks thereon,

The Fig. l of the drawings, illustrates the outlines of a standard toilet unit A and water supply tank as used therewith, in its installed position adjacent an ordinary hollow partition wall.

.nited States Patent 2,824,313 Patented Feb. 25, 1958 My invention is confined solely to the special toilet seat and connected wall ventilator exhaust system, but in no way interferes with the ordinary toilet unit use, or operation.

The unit design herein illustrated is especially adapted for construction of plastic, or similar materials, although it is to be understood applicable to any suitable material adaptable to the required design formation.

The toilet seat assembly, as illustrated in the Figs. 1 and 2 of the drawings, is formed of the ordinary standard exterior shape and design, comprising a seat unit 1, and cover unit 2 hingedly mounted thereon at the back end, by ordinary hinge units 3 rigidly projected from the seat upper wall. The cover 2 is preferably made of the hol low design, as illustrated in the Fig. 4 of the drawings, and is provided with the usual resilient contact buttons 10, for noiseless contact with the seat unit in closing therewith, as in the ordinary construction.

The seat unit 1 is preferably oval in exterior design, formed with a similar central oval opening a symmetrically positioned therein, and is provided with an extended parallel wall hinge block b projected from the back end thereof, the entire unit being constructed hollow throughout, forming an inner air ventilating chamber 0 therein. The hinge block b is enlarged at the outer end and is formed with cylindrical bearing openings d through opposite side walls, cross-wise thereof, positioned at right angles to the seat centerline, and opening into the ventilating chamber 0. ithin the seat bottom edges e and f are formed central flange grooves 4 and 5 extending the full edge lengths completely surrounding said unit edges. A thin base plate 6 of exact seat unit exterior design, is fixedly mounted beneath said hollow seat chamber 0 and joined to the seat edges 2 and f by projected base flanges g and it formed symmetrically therewith, thus in closing and sealing the ventilating chamber 0, said base plate 6 being fixedly attached thereto by an extended seat end flange k and by special release snap hooks 7 attached to said seat inner chamber walls. The base plate 6 is designed with special air intake openings 8 formed therethrough, preferably positioned near the seat inner opening a. The base plate is also provided with a thumb recess 9 positioned near the snap hooks 7, for easily removing said plate when necessary. Within the hinge block b is mounted on open electric contact switch unit 11, fixedly attached to the recess end wall, designed with a contact button 12 projected from the bottom wall thereof, and extended through the seat base plate 6, engageable with the toilet bowl edge, as is illustrated in the Figs. 1 and 4 of the drawings, said switch unit 11 being connected within an electric circuit by the terminal cord wire 13 leading to the exhaust power unit B, and connected power wall plug.

Through opposite seat bearing openings d are mounted tubular bearing units 14, each fixedly mounted within a circular support collar 15, supported by fixedly attached mounting rods 16 positioned at right angles to the collar center-lines. Both mounting rods 16 are slidably mounted through vertical slide bearings 17 rigidly clamped to the toilet A Walls, as illustrated in the Fig. 5, and provide adjustable hinge support means for the chambered seat unit 1. Resilient contact buttons 18, preferably rubber, are fixedly mounted on the forward end of the seat base, designed and positioned to engage the toilet bowl A edges at all times. Also spring contact buttons 19 are adjustably mounted near the back base plate edge, projected therethrough, allowing said seat unit to depress slightly when weight is placed thereon, and automatically depress the switch contact button 12, closing the terminal switch 11 controlling the exhaust unit B.

The preferred exhaust unit B is an assembly formed of a standard combination pancake motor-fan unit C now in common use (or any other similar unit). This combination motor-fan assembly comprises a small, thin motor ,unit 20 mounted within a supporting casing 21 suitable for installation within a building partition wall, said motor being inclosed by a squirrel cage type of exhaust fan unit 22 also mounted on the same drive shaft, as illustrated in the Fig. 7 of the drawings. The air intake 23 leading into the, fan unit is centrally located on the motor side wall, preferably through a special wall cap plate 24, and enters the exhaust fan 22 around the motor outer edge, the air being discharged therefrom through the outlet duct 25 mounted on the fan casing circumference and extended up through the partition wall recess leading to an outdor discharge outlet. The air intake 23 is connected to the seat tubular bearing unit 14 by connected flexible dual pipe sections 26 mounted therebetween, as illustrated in the Figs. 1 and 2 of the drawings, and with the electric cable 13 electrically connected to both the motor 20 and extended to the electric power source through the attached wall plug unit 27, operative whenever weight is added to the toilet seat assembly, depressing same and closing the control switch 11.

While I have illustrated my device with the exhaust unit B mounted within a vertical side wall recess, it is to be understood that the exhaust unit may also be readjusted for mounting within the floor recess beneath the toilet unit A equally as well, and the flexible pipe units 26 displaced to enter inside the toilet walls through special side openings 28, as indicated in the Fig. 1, and projected downward to the exhaust intake 23 as in the former case, the operation is exactly the same as previously described. In some cases the outlet pipes 26 may be substituted with special channel recesses 29 formed directly within the toilet unit, as isillustrated in the Fig. 1 of the drawings.

Having fully described my electric toilet seat exhaust ventilator, what I claim as my invention and desire to secure by letters patent is:

I claim:

An electric toilet seat exhaust unit ventilator adapted for air ventilation of a toilet unit, and used therewith, comprising a hollow, recessed, oval shaped toilet seat unit formed with a projected hollow end hinge block thereon, tubular hinge bearing units mounted cross-wise through said projected hollow hinge block and opening therein, vertical adjustable bearing units fixedly mounted over said tubular bearing units and slidably mounted in the adjacent toilet unit walls, an open push button electric switch fixedly mounted within said seat hinge block projection, engageable with the toilet wall, a perforated base plate fixedly mounted over said hollow seat recess forming an air ventilation chamber throughout, flexible air outlet tubes mounted on the said tubular bearing units, an electric motor-fan air exhaust unit fixedly mounted within an adjacent building Wall recess opening and connected to said flexible air outlet tubes leading to the seat chamber, an air exhaust outlet passage channel mounted within the building wall and connected to the exhaust unit outlet, electric cable means for operatively connecting the exhaust motor with an electric power source through the push button control switch unit when the toilet seat is depressed in use, and spring release button means mounted on the seat base, engageable with the toilet walls, for raising said toilet seat and for opening said electric control switch when not in use.
