2. Claims.
The present invention relatesto new andiuseful improvements in toilets, and, more; particular] to ventilating meansfor the toilet bowl,
important object. of the present: invention is t'o provide a toiletbowl havingabuilt-in. ventilating system for withdrawing fumesv and; odors from the interior of. the. bowl; and. including a ventilating passage in the rim of. the bowl having a suction fan attached thereto for removing the fumes and odors from the bowl and discharging the same into the waste pipe.
A further. object of theinvention isto provide manually operated valve means between the waste pipe and the ventilating passage leading from the bowl to prevent fumes from the'waste pipe backing up into the bowl when the suction fan is-not; in use. I
A still further object of the invention: is to; provide a toilet bowl including awater flushingrpassage around the inside of the rimthereof, together with a: ventilating air, passage- :also extending aroundthe rim of the bowl; and in whiclrs-the intake for the air passage is arranged with respect to the water passage to prevent water from entering into the air passage while the bowl is being flushed.
A still further object of the invention is to provide a ventilated toilet bowl of simple and practical construction, which is neat and attractive in appearance, relatively inexpensive to manufacture and maintain in operation, and which otherwise is well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like reference numerals refer to like parts throughout, and in which:
Figure 1 is a top plan view with parts broken away and shown in section, and the flush tank, cover plate, and motor removed,
Figure 2 is a vertical sectional view taken substantially on the line 2-2 of Figure 1, and
Figure 3 is an enlarged detail in side elevation of the control knob for the switch of the suction fan and for operating the valve of the air passage.
Referring now to the drawings in detail, wherein, for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a toilet bowl having a chamber 6 formed at its rear portion and above which is mounted the flush tank 1. Access to the chamber 6 is afiorded by way of a cover plate 8 secured to the lower, front portion of the tank I 2 andextending'downwardly behind the seat!) of the bowl; 1
The bowl' 5-include's a. rim i0 extending inwardly around theupper edges; of. the-bowl and in which is formed a water passage ll having an: opening 12? at itslower portion-for dischargingwater along the inner walls of. the bowl in. the; usual: manner, the water passage H: being connected; to: the tank I in. the usual manner for: receiving water from the tank.
The rim ill is, alsoformed with an air passage l3 positioned inward-1y of the water passage; Hi, the air passage also, being formed at. its lower portion with an inletopening: 1 4;.
:The air passage; I13 at thezrear; of-thebowl is formed with a. neck i5v which extends upwardly into the chamber 6 and laconnected to the neck I6 of a motor'housing I?! positioned in the cham ber B by meanso-f a flexible coupling l8 An electric motor l9 is. mounted in .avertical position in. the, housing If! with.- the shaft. 21! of the motor projecting, upwardly therefrom and to which is attached a plurality of suction fan blades 2|. The motor I9 is spaced from the walls of the housing I! and the housing terminates at its lower end in a neck 22 detachably connected to the upper end of a conventional form of valve housing 23 having a valve 23a of a butterfly type mounted therein and operated by a rod 24 connected at its lower end to the valve arm and extending upwardly in the chamber 6. The lower end of the valve housing 23 is connected to a passage 25 which leads into a waste pipe (not shown) to which the discharge passage 26 of the toilet is also connected.
The electric motor I9 is controlled by a toggle switch 21 of conventional constructoin mounted in the chamber 6 adjacent one side thereof, the switch handle 28 being moved forwardly and backwardly to turn the switch on and off in the usual manner by means-of a channel-shaped cam 29 secured on a shaft 30 journaled in the side of the chamber 6 and having an operating knob 3| secured to its outer end. An arm 32 also connects the inner end of the shaft 30 to the upper end of the arm or rod 24 for simultaneously opening and closing the valve 23a as the motor is turned on and oi'l" by the switch 21.
As more clearly illustrated in Figure 2 of the drawing, the lower edge of the rim l0 slopes upwardly toward the center of the bowl, as indicated at 33, by reason of which the inlet openin M for the air passage I3 is positioned on a horizontal plane above the discharge opening 12 for the water passage ll. Accordingly, water dis- 3 charged from the passage I I will not collect in the air passage 13 and likewise the water will not be drawn into the air passage by the suction fan 2! while the toilet is being flushed.
The valve 23a is arranged for movement into its open position when the switch is turned on for operating the motor I9 and the valve is closed when the switch is closed in order to prevent fumes and odors from the waste pipe returning to the bowl through the air passage.
In view of the foregoing description taken in conjunction with the accompanying drawings, it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.
It is to be understood, however, that even though I have herein shown and described a preferred embodiment of my invention that the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.
Having thus described the invention, what I' claim as new it:
1. A ventilated toilet comprising a bowl having a rim projecting inwardly at its upper edge and with its bottom inclined upwardly, said rim having a water passage and an: air passage, the air passage being positioned inwardly of the water passage, and each passage having an opening in the inclined bottom of the rim, with the opening for the air passage positionedabove the horizontal plane of the opening for the water passage to prevent entrance of water into the air passage, said bowl also having'a chamber at its rear portion and a waste passage at its bottom, a motor housing mounted in the chamber and connected to the air passage and to the waste passage, a motor-operated suction fanin the housing for exhausting fumesfrom the bowl into the waste passage, a valve between the housing and the waste pipe, a switch for the motor of the fan and including a toggle lever, a manually operated shaft journaled in one side of the chamber, a cam on the shaft operatively engaged with the toggle lever to open and close the switch, and means operatively connecting the shaft to the valve for simultaneous opening and closing of the valve and switch.
2. A ventilated toilet comprising a bowl having a rim projecting inwardly at its upper edge and with its bottom inclined upwardly, said rim having a water passage and an air passage, and each passage having an opening in the inclined bottom of the rim, said bowl also having a chamber at its rear portion and a waste passage at its bottom, a motor housing mounted in the chamber and connected to the air passage and to the Waste passage, a, motor-operated suction fan in the housing for exhausting fumes from the bowl into the waste passage, a valve between the housing and the waste passage, 3. switch for the motor of the fan including a toggle lever, a manually operated shaft journaled in one side of the chamher, a cam on the shaft operatively engaged with the toggle lever to open and close the switch, and means operatively connecting the shaft to the valve for simultaneously opening and closing of the valve and switch.
