Description
- The present invention relates to a toilet hygiene unit having automatic cleaning apparatus.
- Different types of toilet provided with automatic cleaning apparatus, both for public toilets and for private bathrooms are known. In general, it is essential to wash the bowl in such a way to eliminate any trace of either liquid or solid excrement, and to wash and disinfect the parts which come into contact with the human body.
- In a known type of toilet, such as EP-A-0,274,588, there is provided apparatus for washing, disinfecting and drying the seat, which apparatus comprises a tank disposed behind the seat, closed by a vertically slidable door. This tank is divided by a vertical dividing wall carrying a series of nozzles disposed in a vertical ring of form corresponding to the seat. A mixture of water and disinfectant is first supplied through this series of nozzles. The ring shape zone further has a series of holes for the passage of hot air from a fan.
- In another type of toilet the seat is washed by means of a rotating double arm having two sets of nozzles at two ends. This arm is also disposed within a vertical tank positioned behind the bowl and closed by a door hinged at its upper edge. The rear edge of the toilet seat is mounted on a vertically movable carriage disposed in the tank. When the seat is lifted to the vertical position in the tank, the door automatically closes. At this point rotation of the washing arm commences and subsequently a current of hot air is generated in the tank.
- This known toilet has the disadvantage that the door in the vertical tank, when closed, forms the seat back of the bowl, which comes into contact with the user's body. Therefore, it cannot be washed automatically by the cleaning apparatus.
- The object of the invention is that of providing a toilet hygiene unit having automatic cleaning apparatus, which will be of maximum simplicity and will eliminate this and other disadvantages of known toilets.
- This object is achieved with the hygiene unit according to the invention which comprises a bowl provided with a flushing system and having a liftable seat and a seat back, said apparatus including at least one seat washing, disinfecting and drying device, and being characterised by the fact that the said device is operable to act simultaneously on the said seat in the vertical position and on the said seat back.
- According to another characteristic of the invention, the said seat is provided with a series of nozzles which are supplied during use of the said bowl to create a film of water on the inner surface of the said bowl in such a way as to inhibit the attachment thereto of organic substances.
- For a better understanding of the invention a preferred embodiment is described here by way of example only, with the aid of the attached drawings in which:-
- Figure 1 is a partially sectioned perspective view of a toilet including a hygiene unit according to the invention;
- Figure 2 is a schematic left side section of the toilet of Figure 1;
- Figure 3 is a partial right side section of the hygiene unit;
- Figure 4 is a partially sectioned front view of the hygiene unit; and
- Figure 5 is a block schematic diagram illustrating the functions of the control unit of the hygiene unit.
- With reference to Figure 1, the
reference numeral 6 generally indicates a toilet for public or community conveniences, which comprises afloor 7, two side walls 8 and aback wall 9, advantageously provided with a glass window 11. Thetoilet 6 is closed by a door known per se, and therefore not illustrated, which can for example be of the type openable by money or tokens. - The
toilet 6 is provided with the usual attachments for water and electricity and with the usual waste pipe 12 (Figure 2) connected to the drain. Thefloor 7 is provided with asump 13 for the collection of small refuse items such as cigarette ends, and liquid such as the washing water from thetoilet 6. Thesump 13 is covered by afloor grille 14, which allows the passage of liquids and other small refuse items into thesump 13. This latter is provided with asyphon discharge 10 for evacuation of such liquids and refuse items to the drain. Thegrille 14 is further provided with an edge 15 (Figure 3) carrying a series ofnozzles 16 for washing thesump 13. - The
toilet 6 is furnished with a monobloc sanitary unit generally indicated 17, which includes abowl 18 fixed to acasing 19 of substantially rectangular form, which houses the entire automatic cleaning apparatus of the unit and is covered by three removable panels. One of these panels indicated 20 in the drawings, is disposed above thecasing 19, and is adapted to be removed to allow access to the electrical and mechanical parts for suitable connections and maintenance. Thecasing 19 has aplinth 21 at its end for connection to thegrille 14. Theplinth 21 is provided with a series of nozzles 25 (Figure 2), also provided for washing thesump 13. - The
bowl 18 is provided with theusual seat 22 formed as a ring or annulus on which the user is to be seated. The rear edge of theseat 22 is provided with a projection 23 (Figure 3) fixed to ahollow shaft 24 which is rotatable in a housing 26 (Figure 4) disposed within thecasing 19. Theshaft 26 is turned by ashaft 28 of a reversible gearedmotor 29 via motion transmission means comprising a lead screw andnut 27. Therefore theseat 22 can be rotated about its rear edge from the horizontal use position indicated in Figure 2 to the raised or vertical position indicated with broken lines in Figure 2. - The
casing 19 is provided with anaperture 31 disposed behind thebowl 18, which is normally closed by a seat back 32. Advantageously theseat back 32 can have the same shape and dimensions as theseat 22 so as to allow this latter, when raised, to lodge in theaperture 31. Theseat back 32 is mounted on an articulated parallelogram linkage comprising a pair ofequal arms 33 and 34 (Figure 3) pivoted ontoprojections 36 of thecasing 19. - To the
arm 33 is connected an articulated link 37 which, by means of apivot 38 is articulated to alever 39 pivoted to anotherprojection 41 of thecasing 19. Thepivot 38 is mounted on anut 40 engaged with ascrew 42, which is rotated by a reversible gearedmotor 43. The actuation of the gearedmotor 43 causes displacement of theseat back 32 parallel to itself from the use position indicated in solid outline in Figure 2 to the washing position indicated in broken outline. - The automatic cleaning apparatus essentially comprises a device, generally indicated 44 (Figures 2-4) for washing, disinfecting and drying the
seat 22 and theseat back 32. Thedevice 44 is carried by acarriage 46 which is mounted on a pair ofwheels 47 guided vertically in suitable guides of thecasing 19. The guides are disposed in such a way as to cause thedevice 44 to move in the space between theseat 22 in the vertical position and the seat back 32 in the retracted position. - The
carriage 46 is displaced by a pair ofbelts 48 each of which engages twocorresponding pulleys casing 19. To abracket 52 of thecasing 19 is fixed a reversible gearedmotor 53 adapted to drive ashaft 54 rotatable in twosupports 55 of thecasing 19. Theshaft 54 carries twowheels 56 of the same size as thepulleys respective belt 48. - The
carriage 46 carries tworubber cleaning wipers 51 one of which faces towards theseat 22 and the other towards the seat back 32. Thecarriage 46 also carries two series ofnozzles seat 22 in the vertical position and towards the seat back 32 in the retracted position. Each series ofnozzles water pump 61. The ducts leading to thenozzles fan 59 which can possibly be connected to an air heater to dry theseat 22 and seat back 32. - In the
casing 19 there is also disposed a cistern, not indicated in the drawings, for the usual flushing system for thebowl 18, which is actuated by means of amanual push button 60. This can also be actuated automatically, for example, by means of an electromagnet, before washing of thebowl 18, as will be seen better hereinbelow. The After each flush, the flushing system cistern is refilled directly with water from the mains. - The
pump 61 is also connected, by means of asolenoid valve 63, to thenozzles carriage 46. Another solenoid valve 64 can be actuated to connect thepump 61, via a duct not indicated, to thenozzles sump 13 under the floor-grille 14. - The
seat 22 is provided with a series ofnozzles 65 disposed on its lower surface close to the inner edge of thebowl 18. Thenozzles 65 are connected to acommon duct 67, connected to thehollow shaft 25, in turn connected to thepump 61 by means of twofurther solenoid valves 62 and 66. These can be selectively operated when the seat is disposed in the horizontal position respectively to create a film of liquid on the inner surface of thebowl 18 and to wash the bottom of thebowl 18 after the operation of the flushing system. - Finally the
casing 19 encloses anapparatus control unit 69 which includes a logic circuit process controller 71 (Figure 5). This controller 71 has a logical step-by-step operation and is provided with a self-diagnosis program which continuously tests for the correct performance of the preceding operation before allowing the successive one. - The
control unit 69 includes a series of circuits controlled by the controller 71 for controlling the various devices of the apparatus. In particular these circuits can be grouped in the following functional blocks:- - a
block 72 operable to indicate the entrance of a user into thetoilet 6 and associated departure, for example by the use of a token device and/or a floor micro-switch; - a
block 73 operable to control the locking and unlocking of the door and the associated light signals; - a
block 74 operable to control thepump 61 and the associated valves 62-64 and 66; - a block 75 operable to control the geared
motor 43 for movement of the seat back 32; - a
block 77 operable to control the gearedmotor 29 for movement of theseat 22; - a
block 78 operable to control the gearedmotor 53 for driving thebelts 48 for displacement of thecarriage 46; and - a
block 79 operable to control the actuation of theelectric fan 59. - The operation of the hygiene unit described above is as follows:-
Upon entrance of the user into thetoilet 6 theblock 72 sends a signal to the process controller 71 which, by means of theblock 73 locks the toilet door. Further, theblock 73 controls the illumination of an external warning lamp indicating that thetoilet 6 is occupied. Possibly theblock 73 may also control the illumination of an internal light and the starting of a fan for forced air change. - Via the
block 74, the controller 71 opens the valve 62 (see also Figures 2-4). This, by means of thenozzle 65, creates a film of water on the inner surface of thebowl 18, which prevents the adherence of organic substances or particles of faeces on this surface of thebowl 18 during use. After use, the user can press themanual push button 60 of the discharge system for a first cleaning of thebowl 18 by means of the flushing system. He can then use possible other sanitary equipment present in thetoilet 6. - When the user leaves the
toilet 6 the door automatically closes and initiates a more thorough cleaning of thebowl 18, a cleaning, disinfecting and drying of theseat 22 and the seat back 32, and a washing out of theunder floor sump 13. In particular, the controller 71, by means of theblock 74, now causes the automatic emptying of the flushing system cistern if thepush button 60 has not been operated manually. Moreover, by means of theblock 74, it now starts thepump 61 and operates the solenoid valve 66 which, via thenozzles 65 of theseat 22 effects a thorough washing of the interior of thebowl 18 with a high pressure jet of water. - At the end of the bowl washing phase, the controller 71, via the
block 76, causes actuation of the gearedmotor 43. This drives themechanism block 77 puts the gearedmotor 29 into operation carrying theseat 22 into the vertical position. - Now the seat and seat back cleaning phase starts. For this purpose the geared
motor 53 is put into operation by theblock 78. This now displaces thecarriage 46 between theseat 22 and the seat back 32, first downwardly and then upwardly so that therubber wipers 51 remove any possible particles of dirt. - Moreover, during the downward displacement of the
carriage 46 theblock 74 operates thesolenoid valve 63 so that thenozzles seat 22 and the seat back 32. on the other hand, during the upward displacement of thecarriage 46 thesolenoid valve 63 is closed whilst theblock 79 operates theelectric fan 59 so that theseat 22 and the seat back 32 are dried. - This operation can be repeated automatically a predetermined number of times, for example three times. Alternatively the process controller 71 can be programmed in such a way as to control washing during a complete descent and rise excursion of the
carriage 46, disinfection during a second complete excursion and drying during a third excursion of thecarriage 46. - Then, via the solenoid valve 64 and the
nozzles sump 13 under thegrille 14. Finally, via theblock 77, the controller 71 controls energisation of the gearedmotor 29 which causes theseat 22 to return to the horizontal rest position, and via theblock 76 controls the gearedmotor 43 which causes the seat back 32 to return to the forward position. After these operations the controller 71, via theblocks toilet 6 and the associated external indication. - From what has been seen above, the advantages of the hygiene unit of the invention over known units are evident. In fact the
device 44 performs cleaning not only of theseat 22 and thebowl 18 but also cleaning of the seat back 32. Moreover, thebowl 18 is continually washed with water by means of thenozzles 65 of theseat 22 both during use and for the purpose of energetically washing during the flushing effected by the flushing system. Finally the monobloc 17, by means of thenozzles underfloor sump 13 under thefloor grille 14, and allows easy installation of the unit in thetoilet cubicle 6. - It is intended that the hygiene unit described can have modifications and improvements introduced thereto without departing from the ambit of the claims. For example, the nozzles of the plinth 21 can be dispensed with and the
grille 14 can be separate from thecasing 19. Moreover, thecarriage 46 can be driven by different means, for example, by means of a linear motor. Finally thepump 61 can be of variable pressure, or else may be replaced by two low pressure pumps or by a low pressure pump and a high pressure pump.
