Internally to the space bordered by the inner shell 49 there is defined a bowl seat, generally designated with the reference numeral 109 whioh ha~
a concave upperplatform 11 con~er~k~ w4~h it~ mdddle p~rtion into a first Swmp ~or~atio~ 12 at th~ ~id~ ~hereoi support elements 13 are located which are advantageous-- 6 ~ C~
ly made piYotable about a subs~antially vertical axis for swinging outwardly during the flushing operations, as will be described hereinafter~
The firs~ ~mp formatiQn 1~ op~ at th~ bottom ~nto 5 a lower sump :~o~a~o~ 14 w~ch, ~Rith the i~terpo~tio~ o~
a conventional siphon trap 15; is connected to a drain conduit generally indicated at 16~ .
Advantageou61y7 at the outlet from said siphon trap and at a location that carmot be reached inadvert-ently, there may be provided a ~a~age chopper 17 toprevent possible clogging o~ the drain conduit.
The ~l~ r 0~ the ci~d ~ is co~ d o:e a ~srid 20 ~ c~tr~ls ~ 3i~g the u~r~ ~ weight to initiate the apparatus operating cycle. Said grid is positioned above a collecting trough 21~ which 1 connected through an auxiliary siphon trap 22 to the cited drain conduit 16.
The apparatus according to the invention further i.ncludes, on the interior thereof, noz~les deli~ering flushing water for the cited lower sump 14, as indicated at 30, which are arranged to continously admit water into the lower ~ump; also provided are flushing water delive~y nozzles 31 for flushing the lower areas of the inner walls and sump~ which ~5 extend in a recess defined peripherally by the inner shell so as to form in practice a water curtain which sweeps the wall~ as w~ll a~ the area a~oY~ the c~nca~o - plat~rm 11 of the bowl 8~at 10~ i~ order to convey the wat~r into the ~irst ~ump a~d the~c~ to th0 drai~.
3~ Provided on the inner wall at the area o~ the side 7~ ~2~L~J~
of the bowl seat 10 are large handle~ 40 whîch are pro~ided with disinfectant l:iquid delivery nozzles whose jet mainly spans the support ~uxfaces d~fi~ed by the bo~l seat, while hot air delive-ry outlets are 5 provided for drying the cited support ~urface~.
The apparatus further comprises, within the cited space 6~ an a.utomatic door opener 39 which can be coin~operated, an au-tomatic eontainer 41 o~ paper seat cover~ which has a ~lot 42 toward the space interior~ and a container 43 of toilet paper of the automatically dispensing type with a di~pensing slot 44.
Again in the intershell space, there is defined a flushing compartment 5G which includes a liquid ~5 soap container 51, a fouled air extractor 52 toWara out~de~ and a water dispensing faucet 53 and hot air drier 54, which are all accessible through a mouth or opening 55 provided at the sidewalls of the ~pace delimited inside the boothO
Above the cited mouth, there is preferably pro~ided a mirror 60.
Provided on the booth floor, moreover~ is a pedal control 70 for controlling the delivery of hand washing water, a pedal or pushbutton control for 25 opening the door , indicated at 71, and a warning pushbutton 72.
On the booth exterior~ vacant-occupied indicators - are displayed, as well as an optional alarm indicator.
The use and operation of the self-cleaning ~ sanitary apparatus according to this invention are - 8 - ~2~
quite simple and automated~ In fact 3 the user is only re~uired to drop one or more coins into the aecess door opening automatic mechanism ; the intro-duction of the coin will cause the door to open automatically, as well as switch on the "occupied"
indicator on the outside and the light on the inside, start the air extractor, and switch on any internal lighted display informing the user that the apparatus is made a~ailable to him/her for a preset time period.
Upon the user ente~g the apparatus, the pressure exerted on the grid ~0, w~ich forms the floor surface thereof, will cause the door to close automatically, and the delivery of a continuous water 15 flow through the nozzles 30 into the lower sump 14.
~oreover, also automatically, a paper seat cover and a metered amount of toilet paper are dispensed, while a timer is started to count down the time period that the apparatus is to be reserved for the user.
The user, after raising from the seated position,by depressiogthe pedal control 70 on the floor actuates the delivery of hand washing water and soap~
as well as of a hot air jet for drying purposes.
After use of the apparatus, by depressing t~e pushbutton 71 the door is automatically opened.
As the user step~ out, the grid 20, being relie~ed of the u~er's weight, eontrols sequentially the actuation of the following op~rat~Q~ ~ automatic reclosing of the door and switching off of the interior ligh~, and operation of pressuri~ed water o~
jets~ both through the nozzles 30 and nozzles 31, thus providing complete flu~hi~r of the apparatu~i - at the same time, ~he ehopper lc>cated down~tream of the drain is operated to avert occlusion of the drain oonduit; and on completion of the latter step, the disin-fectant iets against the æupport elements 13 are acti~ated~ said support elements being advantageously rotated outwardly to facilitate removal toward the upp~3r ~3ump s~f any l~ft sea~
cover~ which will be then chopped.
Thereafter~ a ~urther flushing ~tep i8 completed, and ~he hot air delivery outlets are operated to dry the support ~ur~ace~.
On completion of the flushing operations, deodorant or ~erfuming substances may be injected such that the apparatus can be le~t perfectly clean and ready ~or subsequent use.
At the end of all the operation~ just described, which will require approximately a couple of minutes to carry out, the "free" indicator will be displayed on the exterior, and the apparatus can be used ag~in i~ ~h~ manner described above. In an emergency~
the u~er can operate the emergency pushbutton 72 whieh, in addition to i~mediately releasing the aecess door lock, activates an i~termittent emergency indicator externally to the booth.
The external emergency indieator and the door release will be operated automatically where the apparatus i~ being used in excess of the time allotted.

affords a thorough flushing action sweeping clean 5 all ~lose areas thereof which are likely to get sQiled~ which action is favored by the reduced pro~ision of 60-called support ~ur~ce~ which are restric~ed in practi.ce to just the seating area.
~ urthermore 9 the absenc~ of protruding elements 10 defeats ~andalic actions, ~ince none of the ~aciliti.e~ are made accessible from the booth interior~
~ e in~ention as conceived is susceptible to many modifications and ~ariations without departing 15 from the true scope of the instant inventi~e concept.
~ 'hus, as an example and as shown i~ ~igure 7~
the outer 6hell ~ and inner shell 4 may be arranged off-centered to each other~ thereby they would be closer to each other at the door 2 and l~ave a wider space at the area where the various actuating mechanisms are accommodated.
MoreoYer, a bowl 80 having a substantiall~
fru~to-conical configuration may be used with an internal flu~hing cyclone, known per se.
~lso pro~ided are disinfectant liquid dispenser means on the support ~ace~ OI the bowl 80, which would compri~e a slab 81 hinged to the bottom edge of ~ opening 82 defined in the shell 4 and being removably closed by a flap 83 which is hinged to the top- edge of s~id operLing.
L~3~0~
The slab 81 is connected to di6infectant liquid dispensers and to a hot air blower 84, and ha~ a ~hape sub~ta~tiall~ matching the top support ~Urf~C~B of said bowl 80. ~hen it i8 to be 5 used, the slab 81 is automatically tilted toward the interior o~ the shell 4 9 raising the flap 83, and locate~ itself above the bowl 80 as indicated in dash lines in Figure 8~ Owing to the proximity of the sl~b 81 to the top ~ of the bowl 80 f effective disinfec-ting and drying actions of the top support ~u~e~ of the bowl 80 can be achieved within a very ~hort time lapse.
All of -the invention details may be replaced with other~ technically equivalent, elements.
In practioing the in~ention~ the materials used9 6ubj ect to their being compatible with the intended application, and the dimension~ and contingent 6hapes m~y be any selected ones to meet individual requirements.
