Abstract

The mechanism has a perforated cylindrical basket and a cutting device for the dilaceration of material. It is mounted at the rear of the toilet bowl. The baskets have openings (6) in sections running around the walls of the basket called perforated crowns (C). The rings of openings are not contiguous and are separated by a small distance (h) which is about half the height of an opening (6). The rings of openings are staggered. The openings are elongated and are longer vertically than horizontally forming an oblong shape. The upper edge of the basket is closed by a cover. The cutting device consists of a blade (37) supported by a hub (7). The blades (30) are arranged around the hub. The knife is fixed to the upper edge of the hub and the blades extend from the lower edge of the side wall of the hub. The blades are placed diametrically opposite each and the sections forming the blades are shaped like a wide angled cone.

Description

DEVICE COMPRISING A PERFORATED BASKET AND A MEANS FOR

  CUTTING FOR THE DILACERATION OF MATERIALS IN A CRUSHER

  MOUNT AT THE BACK OF A WC BASIN

  The present invention generally relates to a material mill mounted at the rear of a W. -C. and more specifically the device comprising a generally cylindrical perforated basket and a cutting means wherein said materials are tapered. In a manner known per se, a grinder or material macerator is in the form of a housing at the inside of which is positioned a tree

  rotated by a motort.

  Only this shaft is an axial shaft which protrudes vertically on either side of the motor and carries at its upper end a cutting means, and at its

  lower end pump means.

  The cutting means is formed by a knife carried by a hub fixed on said shaft so as to be

rotated.

  Around this cutting means is fixed a cylindrical basket receiving materials. This basket presents a

  wall traversed by regularly distributed openings.

  In the usual way, the wall of this basket is made

  in the form of a grill [age square stitches.

  This perforated cylindrical basket is fixed on the upper wall (the engine so that the vertical shaft

  carrying the means of cost is effective with the axis of said basket.

  The evacuated materials of the toilet bowl are produced in the pa-nier by an aperture rprpendc Ula ireà so) n axis provided in its wall

periphery qiq-e.

  The cutting medium ensures the shredding of the materials that are retained by the parok of the basket as long as it is necessary for it to be used.

  The device is still remarkable in that the means of étant'oupe being formed by a knife carried by a hub, blades are disposed at the periphery of this hub. The invention will be better understood thanks to the

  following description given as an example no

  The claim relates to the accompanying drawings in which: FIG. 1 is a side view of a toilet equipped with a dilator after a first embodiment, FIG. FIG. 3 is a figure similar to FIG. 2 for a macerator according to a second embodiment; FIG. 4 is a side view of the deaerator; FIG. basket of the dilacerator according to the invention, - Figure 5 is a top view of the cutting means of the diacerator according to the invention - Figure 6 is a sectional view along the line

V-V of Figure 4.

  Referring to FIG. 1, there is recognized a known device C: npr () containing a toilet bowl 1, a flush toilet 2 and a housing 3 from di lacerator. The water and the materials which it entrains when emptying the tank of water beans pass from the tank 1 to the tank 3 by the line 13 having,

  for example, a bellows connection.

  A sealed housing 4 containing means for controlling and controlling the operation of the grinder such as pressure switches is provided in the housing 3 generally parallelepiped. This housing is connected to the electricity distribution circuit by a wire provided with a

conventional form 5.

  The means ensuring the delamination of the materials consist of a basket 6 and a hub 7 carrying a knife 37. Said hub 7 is mounted at the upper end of a vertical shaft, not shown in the drawing, driven by

the engine 8.

  The basket 6 is mounted on the upper wall of said motor 8 by fixing lugs 61, shown in FIG. 4, and has a pipe 16 disposed in the

extension of the line 13.

  A skirt 9 is fastened to the lower end of the motor 8 and forms with fins, not shown in the drawing, carried by the lower end of the green shaft, which provides a drainage system for the evacuation of materials and water to the discharge pipe 1 (0. The suls-set formed of the motor 8 enclosing the vertical shaft and carrying on the one hand the basket 6 and on the other hand the skirt 9 is positlonné away from the lower horizontal bottom d (u box 3 so as to leave

  free access to the pump.

  The discharge pipe 10 has a flap valve

ball It.

  The housing 3 of the dilacerator comprises an air intake 12 closed by a float 14 when the level of

  liquid rises after evacuation of a flush.

  In the embodiment shown in Figure 3, the macerator can be used to evacuate to the pipe 1 (0 of the water arriving in the housing 3 by the pipes 15. Such a device allows to ensure by a pipe (Vacuat 10, the evacuation of appliances other than the toilet, for example a sink, a bathtub,

a washing machine...

  In a first embodiment of the invention and as particularly well adapted to FIG. 4, the basket 6 is made in part and does not have openings (separated stops). by fine jambs like the baskets.It is actually set fn HJ6, Worked at the present time in

It is used in the following manner.

  The Applicant has found that when such baskets are used, the materials tend to become attached to them, which prevents them from passing through the openings in view of their evacuation. if they have already reached quite small dimensions, either to be brought back to the knife for reduction in

smaller fragments.

  I0 These materials create beads on each

  jamb that thickens gradually.

  In addition, long fibrous materials such as hair or residues from the cutting of the toilet paper can hang on one hand on one leg and on another on a second leg more or less distant from the first by covering one or several openings. The applicant has therefore sought a new concept of the openings of the cartilage to avoid these

  clashes of materials the wall of the basket.

  It has found at the end of a large number of tests that, contrary to the fact that the cry can increase a priori, the c-ration of a large number of openings decreases. evacuation perfor- mance as it increases the possibilities of hanging on the walls

separating the openings.

  The openings retained for the following basket

  the invention are widely spaced from each other.

  This large spacing creates large smooth walls on which the long materials can not catch and slide, which allows them to be subjected again to the knife of dilaceration. If long materials have passed through an opening on a small portion of their length while they have remained largely in the basket, the rotation of the materials within the basket causes these materials to

  bring the output portion back to the inside of the basket.

g reos.

  Any elongated shape is possible, rectangles,

lozenges, ellipses, etc ...

  An oblong shape is preferably chosen, which makes it possible to avoid any angle likely to retain the

  materials and to propose a large opening section.

  The oblong shapes also have the advantage of providing openings further apart from each other

  only rectangles of the same width and height.

  By way of example, very good results can be obtained with a basket with an internal diameter of 104 mm, the wall of which has oblong openings of 10 mm in width and 15 mm in height, arranged at 50 °. of the others in the perforated C-holes the mean planes of the crowns (perforated, ie the planes on which the openings are centered, being at 23.5 mm from each other in the vertical direction). of the wall similar to a grid of the baskets, anterior wall having oblong holes spaces according to the invention has another advantage in that it fre IneF slightly the flow of

the water outward from the basket.

  In fact, when the water charged with material is discharged from the toilet and enters a basket with a screen-like wall, the water escapes immediately into the housing of the device and the materials projected on the walls do not are not put back into circulation and brought back to

  the inside of the basket for their misplacement.

  With the basket of the invention, the evacuation of the water is slowed down so as to bring back the materials impinging on the water by rotating water in the basket in the manner of the rotarlot in a juteau and thus to iron said matliresos. SUIF fclleta, to ensure grinding

  The opening section of said basket is still important enough to quickly let a large part of the water escape to the housing, otherwise water (hari-qee (e material pL () rrafit remain in the bowl the front cover, a lid not shown at the end of the basket to prevent any passage nor- dilacerated by this side dl rectlion dlu booytier, mainly in the form of

  FIG. 5 represents, seen from above, the hub 7

  knife holder of the dilacerator according to the invention.

  Usually, this hub 7 is generally cylindrical and has a peripheral wall 17 and an upper face, it is traversed axially by a bore 19 through which it is mounted on the vertical drive shaft. Rallying ribs are provided in its inner part but have not been shown in the drawing

so as not to complicate it.

  A line 20 is shaped in the face

  upper 1P, and is lined with pins 21.

  The peripheral wall 17 of the hub carries radial fins> diesutneàs to prevent the winding of mifatiers d la rîmes dll a) itl r (Iuti t hub during the course of the

  As seen in FIGS. 5 and 6, the knife 37 is a parllllogram-shaped blade whose ends 38, 39 protruding from the hub 7 are folded respectively upwardly and downwardly from the plane of the upper face 18, only end 38 folded upwards

being visible in Figure 6.

  This knife is formed by a metal sheet, and is slidably placed in the direction of the arrow A in the groove 20, notches 40 allowing the crossing of the lugs 21 during this movement.
