Definitions

  • the present invention relates to an apparatus for generating and delivering a cascade-like jet of water in a sanitary appliance such as a box shower or the like.
  • the jet in question is strictly dependent upon the feeding pressure which must be relatively low in order to obtain a jet with a considerable flow delivered essentially in a free-fall manner.
  • Devices for generating/delivering a cascade-type jet are widely known in the art and are generally obtained by providing a pump supplying the water to an outlet opening, this pump generally drawing the water from the box shower itself and therefore using recycled water.
  • WO-A-95 02 737 discloses a circuit for recirculating water in a shower box which includes means for producing a cascade-like jet of water where water accumulating means and means for deflecting the water flow are provided immediately upstream of the outlet opening.
  • the present invention relates in particular, even though not exclusively, to an apparatus of this type since, as will emerge from the detailed description below of an embodiment thereof, the pump sucks water from the bottom of the box shower and recycles it into the outflow opening for the cascade jet.
  • the apparatus forming the subject thereof provides, between the delivery of the pump and the outlet opening for the cascade jet, means for braking and accumulating the supply water which ensure that its flow has a relatively low pressure values and an essentially high delivery rate that mainly determines whether the delivery of the cascade jet has the desired efficiency.
  • a further feature of the apparatus herein is that of providing, particularly although not exclusively, means for deflecting the water flow which is directed towards the delivery opening. These means also help, together with said accumulating means, to regulate the outflow of the water.
  • the present invention therefore relates to an apparatus for generating and delivering a cascade-like jet of water according to claim 1.
  • 10 denotes schematically, since it has not been shown in its entirety, the frame of the box shower in which the end wall is indicated by the reference number 10a, its top wall by 10b and its rear wall by 10c.
  • the apparatus comprises a pump for drawing the water and conveying it to an outlet opening which, in a conventional manner, is arranged outside the shower box; the intake of the pump is connected via a pipe 14, to the inside of the shower box with the usual drain 14a.
  • the apparatus is of the type recirculating water as indicated further above, but is configured so as to avoid the generation of a violent jet of water, while providing it with a high flowrate.
  • the supply pump is connected to an outlet opening 16 for the cascade jet via a pipe 18 which, according to the invention, has a suitable form and dimensions as explained in detail hereinbelow.
  • the pipe 18 has, from the bottom upwards, i.e. from the supply pump 12 towards the outlet opening 16, a varying cross-section.
  • the pipe 18 has a first portion 18a, i.e. the bottom portion, which is connected at one end to the pump 12 and at the other end, i.e. the top end, to a second portion 18b, the cross-section thereof is considerably smaller than that of the first portion 18a.
  • connection between the two portions 18a and 18b which is obviously sealed, is achieved by means of a connecting element 20 having a cross-section converging upwards so as to connect without interruption the two portions 18a and 18b.
  • the second portion 18b of the pipe 18 is connected, at its top end, to the third portion 18c which has a cross-section considerably larger than that of the middle portion 18b.
  • This cross-section must be of a suitable size such as to cause at the same time slowing down of the speed of the water flow and, through the regulation of the flow immediately upstream of the outflow opening 16, a jet with a considerable flowrate delivered essentially in a free-falling manner.
  • connection between the portions 18b and 18c is achieved by means of a second connecting element 22 having a cross-section increasing in a continuous manner upwards,which connects without interruption the opposite ends of the two portions 18b and 18c.
  • the function performed by the abovementioned pipe is obvious in that the flowrate of the water will remain unchanged from the inlet to the outlet of this pipe for obvious reasons.
  • the speed and flowrate values of the water,flow will, on the other hand, be variable according to the circumstances so as to generate always a suitable outflow with a relatively low speed and high flowrate.
  • the means for deflecting the water flow mentioned above are incorporated, according to the invention, in the outlet opening and, more precisely, between the upstream portion 16a of the outlet opening 16 and its downstream or exit portion 16b.
  • the longitudinal axes A-A and B-B of the portions 16a and 16b of the outlet opening 16 are inclined with respect to each other, therefore forming a means for deviating the direction of the water flow.
  • this deviation has been set for an angle of about 90° but it is obvious that this novel type of deflector could be provided with a different angle between the abovementioned longitudinal axes.
