  • the reference numbers to indicate similar or equal parts are the same as those of FIGG. from 1 to 4 and 4A.
  • the bowl according to the invention comprises as usual a siphon 3 for the hydraulic closure, and an edge 5 with holes 7 situated below for the outlet of the water. flushing on the point of arriving from a pipe 8; it further comprises, in a known manner, disposed approximately at the rear end of the longitudinal axis of the bowl, means capable of dispensing upwards in an oblique direction, a jet of hot water, for a ablution after the satisfaction of a bodily need, and a jet or breath of hot air for successive wiping.
  • the so-called means are composed of a shower member 9 for the distribution of hot water and of the mouth of a member 11 shaped roughly at a corner, that is to say with walls to sector, which is articulated at 13 to the side walls of a clean housing 15 in a box fixed in the retracted position in an opening 16 under the edge 5 of the bowl.
  • the member 17 is in communication with the front end of a tube 17 for supplying hot air, through a slot 18 obtained on its rear wall, the tube 17 protruding, in the rest position, the slot 18.
  • a inside the member 18 a tube 19 extends, into which the hot water arrives, which tube has at its own end the shower member 9 and which is made flexibly to allow angular movement, in the direction the arrow f11 (or in the opposite direction) of the member 11.
  • the shower member 9 is connected by means of rods 20 to the walls of the member 11, so as to be able to move in solidarity with it, while a closure plate 21, previously integral with the member 11, completes the wall of the bowl when in the vertical position, closes the housing 15 by hiding the member 11.
  • the plate 21 is fixed by means of screws or d other to the anterior wall of member 11, from which it projects below for serving r also closing the opening 16 made in the body of the bowl 1.
  • the member 11 and the plate 21 are turned in the direction of arrow f11, they take the position of use shown in FIG. 4A, that is to say the position in which the shower member 9 spurts hot water for ablution and the mouth 11 B of the member 11 emits hot air for wiping.
  • the angular movement of the member 11, and consequently of the plate 21 is controlled by a bar whose end generally of square section engages in a hole 25, also square, of a side wall of the member 11 and it is operated by a small handle lever 27 arranged on one side outside of the bowl 1 (compare FIG. 2 and 3).
  • the operation of the small lever 27 makes operational the electrical controls also (not shown) after which begins the operation of the devices by means of which the availability of hot water and hot air is obtained respectively for the ablution and for the 'wiping.
  • the heating approximately to the body temperature of the water intended for ablution - which is normal cold water coming from the domestic hydraulic installation - takes place by means of an exchange. rapid heat between the hot air which will be used for wiping and the said cold water, the exchange taking place upstream of the distribution mouth 11B.
  • the air for the said exchange first and for the wiping afterwards, is sucked from the atmosphere, and then pushed at high speed and also heated at relatively high temperature by a device 29, structured like a common hair dryer in which a propeller fan 31, actuated by a small electric motor 33, pushes the air by passing it inside a pipe 35, through a spiral of electric resistors 37; the spiral 37 is wound on an insulating refractory support disposed axially inside the pipe 35.
  • the air which is heated to 80 ° - 90 ° approximately, continues to l 'interior of the pipe 17 in which the pipe 35 extends and which represents the envelope of the true heat exchanger.
  • This exchanger has special characteristics which make it suitable for achieving the aims of the invention.
  • a pipe 41 adducting cold water, which ends with a head 43 for subdividing the flow, supplied by the pipe 41, into partial flows which run through a plurality of pipes 45 of relatively small diameter and having thin walls, to promote heat exchange.
  • the pipes 45 are of considerable length but, in order to reduce the bulk in the axial direction and increase the extent of the exchange surfaces, they are arranged in the tube 17, so as to form groups 40 of concentric spirals; with such an arrangement, suitable radial distances are provided between the turns of a spiral and those of the spirals with respect to it which are more internal and / or more external; in addition, an appropriate radial distance is left between the more external spiral and the wall of the tube 17, and the internal diameter of the more internal spiral is capable of allowing the passage of an appreciable portion of the hot air blown by the device. 29.
  • the air initially at 80 ° - 90 ° C after passing through the groups 40, exits at a reduced temperature, that is to say at approximately 40 ° - 45 ° C, while the water is distributed by organ 9 at a temperature of 37 ° - 38 °, that is to say very close to body temperature.
  • a reducer pressure 51 of the water disposed upstream of the pipe 41 for supplying cold water capable of guaranteeing the passage of an almost constant flow of water through the pipes 45.
  • the passage hole through which the pipe 41 penetrates inside the pipe 19 is sealed outside of said pipe, so as to avoid possible introduction of unheated outside air into said pipe.
  • Tubing 17 may have a curved formation, as shown in FIG. 1, but it can also be made straight, making it easier to build the group.
  • the device 29 for sucking in ambient air, blowing it and heating it could be arranged or oriented in a position different from that with a vertical axis shown, for example, in FIG. 1.
  • the assembly composed of the device 29 and the tubing 17 which contains the heat exchanger formed by the groups 40 can be considered as an appliance-assembled, adaptable, by varying the reciprocal arrangement of the components, to the bowls to which it should be applied.
  • the electrical circuit of the device includes an appropriate timer, which at the start of the cycle arranges the opening of the water a few moments after the flow of heated air is started inside the pipe 17 so as to prevent the water for ablution from initially becoming cold and obtain heat exchange as soon as it begins to pass through the pipes.
  • Said timer moreover, closes after a certain period of time, sufficient for ablution, the distribution of the heated water and concomitantly with said closing command, it reduces by means of switching or otherwise the power of the electric heating resistors; this for economy and even to avoid that the heated air, which continues to be distributed, tends to reach excessive temperatures, either for the user, or for the exchanger pipes, when the heat exchange between the hot air and cold water coming in will finish.
  • the timer After a further period of time, during which the hot air continues to be distributed for wiping, the timer also closes the jet of hot air and restores the initial situation of the circuit.
  • the use of the mentioned timer can make it possible to vary the times of washing and wiping operations at the time of installation or adjustment of the appliance, or even to adapt to changed seasonal situations.
  • a summer-winter switch could also be provided, capable of modifying the times respectively for ablutions and for wiping, in the two different seasons, by operating on the timer.
  • thermostat for controlling the air temperature downstream of groups 40, so that it does not exceed 40 ° 45 ° C, and in addition a thermostat generally at halfway between heads 43 and 44 as well as a safety thermostat in contact with head 44 to control that the water temperature does not reach dangerous values.
  • the means for distributing the hot water jet for ablutions and the hot air jet for wiping, as well as the apparatus for obtaining water and heated air, are installed - rather than in the body of the bowl - in an opening 53 obtained inside the fixed portion 55 of the complex of the pierced chair 57, the said portion being articulated so that it can be lifted either the real pierced chair 60, or the cover 59.
  • the fixed portion 55 can, if necessary, be a little protruding behind the bowl, without however that requiring - in the case of the application of this special complex with a pierced chair - to have to move forward a bowl already installed.
  • the device 29 structured like a hair dryer, blows air on the resistance group 37 inside the tubing 35 which communicates with the tubing 17 inside which the groups 40 of pipes 45 arranged in concentric spirals, which start from a head 43 for subdividing the flow and meet at 9B, that is to say at the base of the shower member 9; the member 9 results inclined upward in a manner suitable for ablutions.
  • the head 43 is located at the end of the portion of the pipe 41 for supplying cold water, which penetrates to the center approximately of the tube 17 at its beginning.
  • the electric opening and closing valve Inside the pipe 17 takes place the heat exchange between the hot air which leaves downstream of the resistors 37 and the water which arrives cold at the head 43 and flows inside the pipes 45.
  • the member 21 S in the open position is housed (compare FIG. 10) in a gap 61 obtained below the wall 63 of the portion 55, where the said portion is lowered to support the cover 59 ; from such an open position, which is achieved by operating the small lever 27, by which it is controlled, by means of a rack and pinion mechanism or the like, the member 21 S is moved to the closed position illustrated in the FIG. 10A, with the reverse movement of the small lever 27, by sliding the conduit in special vertical guides 65.
  • the bar 67 which, by means of the small lever 27, controls the movement of the member 21 S, the electrical controls of the entire device can be actuated located in a box 69.
  • the bar 67 is coaxial with the means for the articulation of the pierced chair 60, with the result of considerable constructive simplicity.
