Definitions

  • the present invention relates to an apparatus such as a washing machine for washing clothes or dishes, an apparatus for dispensing product in solution, etc., provided with boxes for products.
  • the known storage container or box frequently comprises either a side wall open from top to bottom or one or more holes formed at its bottom, intended for the evacuation of the product.
  • the powdered product deposited in a place remote from this open wall or these holes, in the absence of water, remains in a heap and does not go away or spill into the tank. the machine.
  • water is introduced into this box or tank, the pulverulent product is entrained by the water through this open wall or these holes, in the tank of the machine.
  • the storage box or tank has closed walls, and the product is usually discharged by a siphon which starts after adding water to this box or tank.
  • Certain known devices include boxes for products which can receive either a liquid product or a pulverulent product.
  • their structure or shape does not usually allow either rapid or total evacuation of the product or of the conveying liquid which drives out the product and / or economical manufacture, or operation with an absence of moving mechanical parts.
  • the aim of the present invention is to avoid these drawbacks, which makes it possible to produce an economical device in which a universal product container can function equally well with a liquid or pasty pulverulent product.
  • an apparatus provided with boxes of products, the distribution of which during the operation of this apparatus, is done by evacuation by overflow of a mixture formed of these products and of a liquid such as injected water.
  • these boxes includes as product boxes, at least one universal static box operating with a circular vortex of drive water and with overflow.
  • a washing machine 1 comprises a bodywork 2, a tank 3 and a laundry drum 4.
  • the top-loading machine 1 is formed by a door 5 pivoting about a horizontal axis 6.
  • the door 5 is provided in its inner surface 7 with at least one universal static product container 9 operating with a circular vortex of drive water and with overflow.
  • the door 5 comprises a removable assembly 8 of two static twin universal boxes 9 and 10, for powdery, liquid or pasty detergents projecting into the opening 11 of the tank 3 during placing of this together 8 in its operating position, by closing the door 5.
  • These boxes 9 and 10 completely separated by their wall are not communicating.
  • the universal boxes 9 and 10 respectively comprise circular or cylindrical side walls 12, 13, end walls 14, 15, 16, 17 and inlets 18, 19 extended laterally by funnel-shaped spouts 20, 21.
  • the inlets 18, 19 are formed in the circular or cylindrical side walls 12, 13 over only part of their width or height, and closer to the end walls 14, 16 which represent the upper walls of the boxes 9 and 10 when the assembly 8 is in its operating position.
  • the end walls 15, 17 which represent the lower walls are at a level lower than that of the thresholds 22, 23 of the inputs 18, 19.
  • This difference in level or the height of the thresholds 22, 23 defines the maximum dose of product, in particular liquid, which can be retained by the boxes 9 and 10. If its quantity is too large, the liquid product is evacuated by overflowing of these thresholds 22, 23 in an overflow spill.
  • the inlets 18 and 19 of the boxes 9 and 10 are oriented upwards, and the spouts in the form of funnels 20, 21 facilitate the filling of these boxes in powdered, liquid or pasty detergents.
  • this assembly 8 is returned to its operating position (FIG. 1), the doses of detergents found in the boxes 9 and 10 are retained by the thresholds 22, 23 of the inputs 18, 19.
  • the universal boxes 9 and 10 respectively comprise in their end walls 15, 17 which represent their lower walls in their operating position (FIG. 1), holes 30 and 31 for discharging water. Since the liquid products used have a higher degree of viscosity than that of the water used in washing machines, the diameters of the holes 30 and 31 are determined so that these holes allow water to pass but prevent passage liquid products. The dimension of these holes 30, 31 is also determined so that a pulverulent product deposited in these boxes cannot escape through these holes.
  • the washing machine 1 further comprises on the one hand a water injection system 24 of the known type, the nozzles 25, 26, 27 of which are schematically represented in FIG. 2, and on the other hand certain tanks of known type 28, 29 for products such as fabric softener, bleach etc ...
  • the water injection system 24 controlled by a known type of programmer not shown, is mounted in the washing machine 1, opposite the universal boxes 9 and 10 and product bins 28, 29 ( Figures 1 and 2).
  • This system 24 makes it possible to send a jet of water 32 through the nozzle 25 through the inlet 19 into the universal box 10, almost tangentially to the circular or cylindrical wall 13 thereof, via the nozzle 26, a jet of water 33 through the inlet 18 in the universal box 9, almost tangentially to the circular or cylindrical wall 12 thereof, by the two nozzles 25, 26 of water, resulting from the collision of the jets of water 32 and 33, and collected by a gutter 34, in the tank 29, and by the nozzle 27, a jet of water 35, through a hole 36 in the wall 37, in the tank 28.
  • the universal boxes 9 and 10 and the tanks 28, 29 being filled with their respective doses of products and placed in the position of operation by closing the door 5, at a determined point in the washing cycle where the product in the universal box 9 for example must be distributed in the tank 3 of the machine 1, the nozzle 26 sends a jet of water 33 into the box 9.
  • This water jet which is almost tangential to the circular or cylindrical side wall 12, generates a circular movement of water and consequently creates a circular vortex which lifts and entrains the pulverulent, liquid or pasty product in passing being in the box 9.
  • the mixture of water and products, guided by the spout 20, pours into the tank 3 as soon as its level exceeds the threshold 22 of the inlet 18.
  • this mixture being highly concentrated in products at the start of the water injection, gradually dilutes by the arrival of the water and by the evacuation of the mixture by overflow, and becomes, at the end of the operation, only of the water.
  • the programmer stops the water jet 33, and the residual water remaining in the universal box 9 is evacuated through the hole 30 and falls into the tank 3.
  • the walls 12 and 13 are circular walls. These are walls whose cross section forms a closed regular circle or polygon.
  • the non-circular walls are walls formed by an assembly of elements of heterogeneous shapes and lengths. These walls comprise, for example, curved zones mixed by rectilinear or flat zones or bosses or hollows.
  • a jet of water admitted tangentially to these walls cannot create one or more circular vortices which lift and evacuate the products by overflow, but uncontrolled eddies and vortices which sometimes go in opposite directions, neutralize and do not sweep certain areas of the product box, so as to let these products stay there without evacuating them. The efficiency of the evacuation is therefore greatly reduced.
  • the washing machine 1 can comprise a number of universal boxes for products, less than or more than two.
