Definitions

  • the invention relates to a top-loading washing machine having at least one boot for washing products arranged in a pivoting tub door, which door folds horizontally in the closed position, said boot being made up of: two cups, each designed specifically for powder or liquid product and on the other hand a conduit allowing a programmed supply of water to the cups when the door is closed, the liquid washing product being then poured into the tank of the wash by siphoning and the powdered product being spilled by entrainment, the loading of the buckets being possible when the door is open in the vertical position.
  • a machine is known as an example from French patent n 8 2 503 744. It gives the user the possibility of choosing the washing product in powder or liquid form according to his preference.
  • French Patent No. 8 2 503 744 relates to a machine which has a device for receiving and distributing detergents in which there are provided for the washing phase at least two scoops, one of which is intended to receive a liquid detergent and the other intended to receive a powdered washing product, the two buckets being side by side, each having its loading opening.
  • the detergent dispenser has a single water supply line that distributes water simultaneously in the two wells.
  • Such a device has some drawbacks In machines whose programs include a washing phase and a prewash phase, the device must have a box with four cups to allow the choice of powder / liquid for the washing / prewashing phases. Only two of the buckets are simultaneously used, which leads to an unnecessary occupation of space, taken over the width of the tank door, door on which must be adapted two other additional buckets reserved for other products such as softeners and bleach.
  • the bucket loading openings are specific. There is therefore the risk of reversing the functions of the cups and of introducing, for example, a liquid detergent into the powder cup. This mistake leads to an immediate spill of concentrated liquid product directly into the tub of the washing machine. Conversely, introducing a powdered detergent into the liquid cup causes the powder cup siphon to be blocked by the powder.
  • the subject of the invention is a washing machine for laundry, the product box of small overall dimensions which can be used equally for liquid and powder washing products, washing machine characterized in that the two cups of the box have a common loading opening, the powder cup being above the liquid cup when the door is open, a separation separating the buckets and retaining the powder while letting the liquid product pass.
  • the water supply conduit is common to the two buckets, the conduit simultaneously feeding said buckets.
  • the water flow is therefore halved, which affects the proper irrigation of each of the buckets.
  • the separation is a means of supplying water, means which, when the door is closed, is capable of conducting the water contained in the liquid container to the container. powder.
  • the water supply means which moves the contents of the liquid cup into the powder cup can be a siphon bridging the separation, a siphon which draws water from the liquid container to pour it into the powder container.
  • the separation of the buckets according to the invention can be designed in different ways, for example by superimposing two plates pierced with several holes, the holes of each of the plates not being opposite, or even using a grid whose mesh size allows the filtering of the liquid product and the retention of powdered products.
  • the separation separating the two buckets from the boot is a baffle formed by at least two substantially vertical partitions when the door is closed, one of the partitions then constituting a closed wall at the base of the bucket liquid, baffle placed in the middle of the boot above the maximum level occupied by the liquid detergent in the liquid cup when the door is vertical.
  • the first consists in leaving a passage, communicating with the powder cup, opening at the top of it, when the door is closed; the powder is then poured by trickling.
  • the baffle leaves a communicating passage with the powder cup, opening opening in the bottom thereof, when the door is closed. The powder is then poured by a blade of water sliding in the bottom of the powder cup.
  • Figure 1 shows a top-loading washing machine 1, according to the invention, with a door 2 of the tank ajar, door which pivots about a horizontal axis 24. In the thickness of the door are incorporated several boxes for laundry products. On the front wall 3 of the door, the loading openings 4 and 5 of the washing and prewash boots are shown, for liquid and powder washing products. The other two openings 6 and 7 are those of the boots reserved for laundry treatment products such as fabric softener and bleach.
  • Figure 2 is a boot substantially in the shape of a pyramid trunk which occupies part of the space between the outer flat surface of the door and the cylindrical surface of the drum of the tank.
  • the box consists of a liquid product cup 8, occupying the lower part when the door is open, and a powder cup 9 placed above said liquid product cup.
  • the separation between the two powder and liquid cups is a baffle 12 molded above the maximum level of the liquid product, liquid represented in broken lines in FIGS. 2 and 4.
  • the baffle 12 is composed of two substantially parallel partitions 10 and 11 then positioned horizontally and transversely to the box.
  • the partitions of the chicane substantially quadrilateral and molded with the box are secured by three of their sides, to three vertical walls the of the box, thus leaving a passage 13 and a passage 19 both opposite one another and which form with the two partitions a channel 21 between the powder cup 9 and the liquid cup 8 for the flow of the liquid product.
  • the liquid is poured into the powder cup 9 through a common opening 14, and flows through the baffle 12 through the channel 21 to fill the liquid cup 8.
  • FIG. 3 represents a box loaded with a powdered product, the door of the machine being open.
  • the powder is poured into the powder cup 9 through the opening 14.
  • the baffle 12 retains in the lower part of the cup 9 the powder washing product which, in Figures 3 and 5, is shown in dotted lines. Between the two partitions 10 and 11, the flow slope of the powdered product retained just after passage 13 in the channel 21 is materialized.
  • FIG 4 shows the boot loaded with a liquid product, horizontal door.
  • a pipe 15 for supplying water to the boot is composed of a tube forming a portion of torus , integral with the pivoting door, placed above the partitions 10 and 11.
  • the tube is provided, on the one hand with a flared mouth 23 which receives a jet of water emitted by a nozzle integral with the frame of the machine, not shown in Figure 1, and on the other hand of a nozzle 16 placed above the liquid cup, whose flow axis is perpendicular to the wall 17 of said cup, wall which in the present position is the substantially horizontal bottom of the liquid cup.
  • a siphon 18 straddles a wall and makes common screw the liquid cup with the internal space of the tank, the end 25 of the siphon crossing the then lower wall of the boot.
  • a discharge opening 20 located near the common opening 14 and protected by a deflector 22, which prevents a direct discharge of the detergents into the tank during loading.
  • a water supply injects the water into the duct 15.
  • the nozzle 16 directs the water jet towards the wall 17 of the bucket which breaks the jet, causing turbulence and a emulsion with liquid detergent.
  • the emission overflows the partition 11 of the baffle 12, takes the channel 21 and flows into the powder bucket to arrive in the tank through the discharge opening 20 of the powder bucket.
  • the rest of the water, contained in the cup after the distribution of the liquid product is poured through the siphon 18 into the tank of the machine. Indeed, a good evacuation of the liquid product does not require a siphon, because all the liquid product is entrained by water. However, for subsequent loading, the liquid cup must be emptied of the residual water accumulated during the previous washing phase.
  • FIG. 5 represents a box loaded with a washing powder product, horizontal door.
  • the partition 11 is then a vertical wall closed at the base of the powder cup.
  • the same supply injects water into the conduit 15 which by its nozzle 16 fills the bucket with liquid 8.
  • the water overflows the partition 11 flows into the channel 21 and opens out through passage 13 in the lower part of the powder cup 9.
  • the water slides in the bottom of the cup to drive the diluted powder towards the discharge opening 20 which communicates with the tank.
  • the shower formed by the holes 26 of the con feed tube sprinkles the walls of the powder cup and rinses said cup when most of the diluted powder has been poured into the tank.
  • the siphon 18 pours out the rest of the water contained in the liquid cup, after discharging the powder into the tank and stopping the feeding.
  • Figure 6 shows the box in top view.
  • the pipe 15 which forms a siphon is mounted so that after loading with liquid product, door open, it cannot flow through the pipe into the internal space of the tank.
