Definitions

  • the invention relates to a sanitary crusher comprising a tank and a control device for said sanitary crusher placed in said tank, said control device being electrically connected to the outside of the tank by a protected electric cable.
  • the figure 1 illustrates a sanitary crusher 1 of the prior art which is conventionally connected to the bowl of a not shown toilet installation.
  • the sanitary crusher 1 comprises a tank 2 receiving a pipe 4 for connection to the bowl, the latter receiving the waste water and the solid materials coming from the toilets.
  • the connection pipe 4 is connected to a perforated basket 6 into which the waste water and the solid materials coming from the toilets are discharged.
  • the tank 2 also comprises an assembly 10 comprising at least one shredder, a system for discharging waste water and shredded waste, and a motor (not shown).
  • a control device 20, also placed in the tank 2, makes it possible to control the operation of the sanitary crusher and therefore of the assembly 10 (in particular the motor) as a function of the level of waste water in the tank 2.
  • a control device conventionally used comprises a box 30 in which an upper chamber 21 and a lower chamber 22 are arranged.
  • the upper chamber 21 is separated from the lower chamber 22 by a partition wall 23 and is airtight.
  • the upper chamber 21 comprises an electrical control system 24 of the sanitary mill which can include a microswitch 25 (partially visible) as well as a capacitor 26.
  • the engagement of the microswitch 25 which causes the engine of the assembly 10 to start. is done by a deformable actuating element 29 placed on the partition wall 23 ..
  • the lower chamber 22 comprises, at an end opposite to the partition wall 23, a main opening closed by a membrane (not visible).
  • the membrane is able to deform elastically in the direction of the lower chamber 22 under the effect of pressure external to the device, such as for example when the water rises in the tank 2.
  • a vertical rod (not visible) is placed on the membrane and passes through the partition wall 23 through an orifice (not visible) covered by the actuating element 29.
  • the membrane deforms under the effect of the rise of water in the tank 2
  • the vertical rod moves vertically in the direction of the upper chamber and deforms the actuating element 29.
  • the actuating element 29 then comes into contact with the microswitch 25 which causes the starting the engine of the assembly 10.
  • the housing 30 comprises a chimney 33 placed in a sealed manner around an orifice of an upper surface 31 of the housing 30 and into which a sealing washer 35 is inserted.
  • the sealing washer 35 comprises a first orifice 37a and a second port 37b.
  • An air passage 27 enabling the interior of the lower chamber 22 to be placed in communication with the exterior of the device is arranged in the partition wall 23.
  • the air passage 27 emerges from the partition wall 23, passes through the upper chamber 21 and opens into the second orifice 37b.
  • the electrical control system 24 can be connected to an electrical outlet by the electrical cable 42 which passes in leaktight manner through the sealing washer 35 through the first orifice 37a.
  • a flexible conduit 28 is fixed, by a first end 34 and in a sealed manner, to the chimney 33.
  • the flexible conduit 28 comprises an outlet orifice 39 surrounded by first and second molded discs 38a and 38b and joined at a groove 38c.
  • the second end 36 allows the flexible duct 28 to be fixed to the tank 2 at the level of an orifice (not visible) arranged in a wall 40 of the tank 2.
  • the flexible duct 28 is placed in the orifice the wall 40, the periphery of the orifice is inserted in the groove 38c.
  • the first disc 38a is then placed against an inner face 40a of the wall 40 and the second disc 38b is placed against an outer face 40b of the wall 40.
  • the air passage 27 and the flexible conduit 28 into which it opens thus make it possible to put the interior of the lower chamber 22 into communication with the exterior of the tank 2.
  • the membrane moves under the effect of pressure outside the lower chamber 22, the volume of air displaced in the lower chamber 22 by the deformation of the membrane is evacuated towards the outside of the tank 2 by the air passage 27 and the outlet orifice 39 of flexible conduit 28.
  • the flexible conduit 28 also allows the passage of the electric cable 42 in order to be able to connect the electrical control system 24 to an electrical outlet external to the tank 2.
  • the flexible conduit 28 and the outlet orifice 39 have an interior diameter sufficiently large to allow both the passage of air and the passage of electric cable 42.
  • the present invention overcomes this drawback by providing a sanitary crusher which remains functional even in the presence of water and / or moisture around the tank.
  • the sanitary crusher of the invention can remain functional even if it is submerged, thanks to the sealing sheath placed around the electric cable and fixed in leaktight manner to the second end of the flexible conduit. Furthermore, the protective element makes it possible to prevent any moisture from flowing along the electric cable towards the interior of the sealing sheath.
  • a sealing sheath 52 is placed around a part of the outer portion 50 of the cable 42 and comprises a first end 51 and a second end 53.
  • the sealing sheath 52 is made of a flexible and airtight material both water, preferably of polymer material.
  • a flexible conduit 48 differs from the flexible conduit 28 of the prior art in that it has a second end 49 comprising an end piece 57.
  • the first end 51 of the sealing sheath is inserted into the end piece 57 and fixed in a sealed manner.
  • a rigid fixing element 56 is inserted into the sealing sheath at the first end 51.
  • the fixing element 56 is cylindrical in shape and comprises a central part 56b and a protuberance 56a at each of its ends.
  • the first end 51 of the sealing sheath 52 is inserted into the end piece 57 so that the entire fixing element 56 is placed inside the end piece 57.
  • a fixing ring 59 is then placed around the tip 57 and is tightened around the central part 56b.
  • the two protrusions 56a prevent, once the fixing ring is tight, that the sealing sheath 52 does not come out of the end piece 57.
  • the sealing sheath 52 is thus tightly fixed to the second end 49 of the flexible conduit 48 .
  • a protective element 54 is placed at the second end 53 of the sealing sheath 52.
  • the protective element 54 is formed by a cylindrical side wall closed at a first end 58 by a wall solid circular 62 provided with a central opening 64 allowing the passage of the electric cable 42.
  • the periphery of the central opening 64 is placed in contact with the electrical cable 42.
  • this water or moisture cannot pass inside the sealing sheath 52.
  • the lower chamber 22 therefore does not risk being damaged and / or rendered non-functional by water or l 'humidity.
  • the protective element 54 is not closed and is provided, on its inner periphery, with a plurality of channels 62 which are placed in contact with the sealing sheath 52 and which allow passage air between the inside and the outside of the sealing sheath 52.
  • the protective element 54 On the inner face of the circular wall 62 (not visible) the protective element 54 is provided with ribs which prevent the sealing sheath 52 from being placed against the circular wall 62 and which thus allow the passage of air between the inside and the outside of the sealing sheath 52.
  • the sealing sheath 52 lets air pass even when the electric cable 42 is bent. In fact, in the case where the electric cable 42, and therefore the sealing sheath 52, are bent or crushed, the sheath is placed against the electric cable 42 thus creating one or more spaces around the electric cable.
  • the sanitary crusher of the invention comprising the electric cable 42 having its protected outer portion can thus be immersed without damaging the control device.
  • the inclination of the electric cable means that the first end 58 of the element of protection 54 is oriented upwards and that the second end 60 of the protective element 54 is oriented downwards.
  • water or moisture which runs along the electrical cable between the electrical plug 55 and the protective element 54 could not penetrate the interior of the sealing sheath 52. Water or moisture therefore does not risk damaging the lower chamber 22.
  • water cannot enter the sealing sheath through the channels 62.
  • the sanitary crusher of the invention is submersible up to a height of water allowing the protective element 54 to be left out of the water.
  • the protective element can have a shape other than cylindrical and the number and shape of the channels can vary.
