Novel features of construction and operation of the device will =be more clearly apparent during the course of the following description, reference being had to the accompanying drawings wherein has been illustrated a preferred form of the device and wherein like characters of reference are employed to denote like parts throughout the several figures.

In the drawings:

FIGURE 1 is a perspective view of a water closet .and a flush tank and with parts being broken away to more clearly illustrate the several features of novelty,

FIGURE 2 is a sectional view taken substantially on line 22 of FIGURE 1,

FIGURE 3 is a section at right angles to that of FIG- "ice URE 2 and taken substantially on line 33 of FIG- URE 2,

FIGURE 4 is a perspective view, parts being broken away illustrating the housing for enclosing a warm water storage tank and associated mechanism, and

FIGURE 5 is a perspective view of the warm water storage tank, parts being broken away for purpose of illustration.

Referring specifically to the drawings and particularly to FIGURE 1, there has been illustrated a conventional commode 5, having an open seat 6 hinged upon the top of the commode as indicated at 7. A conventional flush tank 8 is connected to the commode in the well known manner and with the flush tank having a rear wall 9, end walls 10 and a front wall 11, all being customary in a device of this nature.

Fixed upon the underside of the seat 6 is a preferably molded plastic water discharge device, indicated as a whole by the numeral 12. The water discharge device embodies a flat head 13 that is fixedly connected to the underside of the rear portion of the toilet seat 6 either by a gummed pad or by fastening screws 15. The discharge device 12 may be molded integral with the seat 6 in such instances where the seat is molded of plastic or other material. Depending from the head 13 is a generally rectangular body 16 formed integral with the head 13 and the lower end of the body 16 is preferably curved as indicated at 17. The body 16 is provided with an angularly disposed discharge opening 18, having a threaded bore 19 that communicates with a conduit opening 20. The conduit opening 20 communicates with a tubular plug 21 that has pressure engagement With a preferably plastic tube 22, that is fitted upon the outlet pipe 23, leading from the warm water storage tank 24, and with the pipe 23 within the tank 24 having an inlet end 25. Also extending into the tank 24 is a cold water inlet pipe 26, that has a vertical flight 27, a horizontal flight 28 and a diagonal flight 29, that terminates adjacent to a heater element 30. Water is forced into the warm water storage tank 24 through the pipe 26 that has a vertical flight 27, a horizontal flight 28 and a diagonal flight 29 that terminates adjacent to a heater element 30. Water is forced into the warm water storage tank 24 through the pipe 26, the water being heated by the element 30 and the water is pressurized from a relatively small sump pump 31, that is disposed within the flush tank 8. Water is drawn from the flush tank 8 and forced upwardly by the pump 31, through a pipe 32, to the pipe 26, which is the inlet to warm water storage tank 24.

Warm water storage tank 24 is mounted within an outer casing 33 and the casing 33, carrying the warm water storage tank 24 and associated elements may be hung by brackets 34 upon the end Wall 10 of the flush tank and outwardly of the flush tank.

Also mounted wtihin the casing 33, FIGURE 4, is a transformer 35, a thermostat 36 and a rectifier 37. The grounded 3-pole plu 38 and a coiled 3-wire conductor cord 39 leads from the source of 110 volt AC domestic electric current. One conductor 40 of cord 39 is grounded to the metal tank and transformer and conductor 41 of cord 39 is connected to one side of 110 volt electric immersion heater. Conductor 42 of cord 39 is connected to one side of thermostat mounted on warm water storage tank. Wire 43 connects other side of thermostat to 110 volt immersion heater. Thermostat is to maintain temperature of the water at degrees plus or minus 5 degrees. This completes the electric circuit for the warm water storage tank heater and thermostat. Wires 44 and 45 are primary leads of volts AC to the transformer which supplies low voltage to the immersed sump pump 31. Wire 46 is low voltage 12 volts AC to the rectifier 37. Wire 47 is 6 volts DC from rectifier to sump pump 31.

Wire 48 is the other low voltage 6 volt DC wire from the transformer to hand switch 49. Wire 51 from hand switch is the other wire to sump pump 31. The operator by pressing switch 49 actuates the pump to force water from closet flush tank 8 to the warm water storage tank 24 and outwardly from the pipe 23 to the spray device 12.

The threaded bore of the spray device 12 receives a threaded plug 50 that is beveled upon its forward end to receive a flexible hot water bottle hose to slip over plug 50 that could function as an enema or a douche attachment however, the plug 50 functions to force an arcuate spray to the anus area. The plug 50, while shown as being threaded into the bore 18, may obviously be molded integral with the spray device 12. The conductor 39 is a 3-wire conductor and the plug 38 is a 3-prong connector. The diagonal fli ht 29 of the pipe 26, at its upper end is provided with a relatively small aperture 52 whereby to prevent a siphoning action with respect to the water in the tank 8 and the pipe 30a leading from the pump 31 in FIGURE 1, passes over the rear wall 9 and its apex, is also provided with an anti-siphon aperture 53.

In the use of the device, the casing 33 is supported upon the end wall 10 of the tank 8 and the plug 38 inserted into a conventional socket having a voltage of approximately 110 volts. The pump 31 is supported within the tank and is coupled to the cold water inlet pipe 26 of the warm water storage tank, as before directed. Now, when the device is to be used as a flushing means for the anus area, or douche, the operator presses the switch 49 energizing the pump 31. Cold water is forced through the several pipes from the pump 31 to the lower section of the warm water storage tank through pipe 26, causing an equal amount of stored warm water to be discharged from outlet 23 through a plastic or rubber tube 22 to the bore 20 of the spray head 12, forcing a spray of warm water in a direction to wash or spray the anus area. When the switch 49 is released, the pump is de-energized but the heater element is constantly operating to maintain the water in the tank 24 at a temperature of approximately 95 degrees by the thermostat 36. The small warm water storage tank 24 has an anti-siphon hole 52 in the pipe 26 whereby to prevent the tank draining when it is layed on its back on the top of the tank 8. When the operator wishes to use the spray for purposes of an enema or douche, the usual flexible rubber hose commonly used with the hot water bottle is engaged over the plug 50 and then the pump actuated again by the switch 49.

The device is simple in construction, has relatively few parts, is strong, durable, cheap to manufacture and most effective as a hygienic spray device, for the anus area and/ or for douching or an enema.

This spray head is a vitalizing feature of this invention:

(1) Can be raised up when seat is raised keeping it clean.

(2) Can be fastened to existing seats or can be molded into new seat.

(3) To be able to slip the hot water bottle hose over the plug 50 so an enema or douche can be accomplished.

(4) Angle of direction of spray against the body is correct for proper washing.

Spray head nozzle is below rim of toilet to get proper angle for the spray to wash properly.

It is to be understood that the invention is not limited to the precise construction shown, but that changes are contemplated as readily fall within the spirit of the invention.
