Definitions

  • the invention relates to a Ein Hugheskasten for a washing machine.
  • the corresponding channel may be formed with a varying cross-section.
  • the setting of the required amount of water can be very expensive depending on the size of the channel component.
  • the present invention has the object to provide an improved Ein Hugheskasten for a washing machine.
  • the invention has the advantage that by using a reducer in combination with a ventilation opening laundry treatment agent can be flushed out of a dispenser of a washing machine with a constant amount of water.
  • the amount of water can be adjusted as required by using differently shaped reducers with little effort.
  • the Ein Hugheskasten has the following feature: at least one Einarrangingkanal for injecting a liquid into a chamber of the Ein Togetherkathtens, the Ein Hugheskanal having an inlet opening, an outlet opening, a arranged between the inlet opening and the outlet reducer for reducing a cross section of the Ein mecanickanals and arranged between the reducer and the outlet venting vent for pressure equalization ,
  • a Waschstoffein seemingly beautifulkasten with a pre-wash, main wash or softener compartment can be understood as chambers.
  • the washing machine can also be a washer-dryer.
  • the liquid may be, for example, water or alkali.
  • the outlet opening can open into the chamber.
  • a reducer may be understood to mean a disk-like or land-like element.
  • a ventilation opening may be understood to mean an opening which permits a fluidic coupling of the dispensing channel to an environment of the dispensing channel.
  • the ventilation opening when the liquid is flushed in, can be arranged in the region of a flow shadow of the reducing piece.
  • a region of a flow shadow can be understood to mean an area behind the reducing piece facing the outlet opening.
  • the reducing piece is arranged in the region of a largest cross section of the dispensing channel.
  • the cross-sectional constriction achieved by means of the reducer can be varied over a maximum range, depending on the dimensions of the reducer.
  • the Ein Hugheskasten may comprise at least one peeling water channel for branching peeling water.
  • the peeling water channel can branch off from the flushing channel at a branch point located between the reducing piece and the inlet opening. It can thereby be achieved that a volume flow of the liquid passing through the outlet opening is significantly smaller than a volume flow of the liquid passing through the inlet opening.
  • the reducer forms a wall portion of the peeling water channel.
  • a cross section of the peeling water channel may be larger than a largest cross section of the flushing channel or, additionally or alternatively, as a cross-sectional constriction of the flushing channel formed by means of the reducer.
  • the flushing channel and the peeling water channel can be aligned perpendicular to each other. Also, by this embodiment, the structure of the Ein Stammkastens can be simplified.
  • FIG. 1 shows a schematic representation of a channel 100 for a capsule rinse in a washing machine.
  • the channel 100 has a cross-sectional constriction 102 to reduce an amount of water flowing through the channel 100.
  • a flow direction of the water is indicated by four arrows.
  • Reference numeral 104 indicates the reduced amount of water for the purge.
  • Branched peeling water is indicated by a reference numeral 106.
  • FIG. 2 shows a schematic representation of a channel 200 for a chlorine rinse in a washing machine.
  • the channel 200 is configured with a reducer 202 for creating a cross-sectional constriction 204.
  • the cross-sectional constriction 204 serves to reduce the amount of water flowing through the channel 200, whose flow direction is again indicated by four arrows. How out FIG. 2 can be seen, formed in the flow shadow of the reducer 202 at a point 206, a negative pressure. Peeled water diverted from the channel 200 is indicated by a reference numeral 208. The reduced amount of water required for the rinsing is indicated by a reference numeral 210.
  • FIG. 3 shows a schematic representation of a portion of a Ein Hugheskastens 300 according to an embodiment.
  • the washing-up box 300 for a washing machine comprises a flushing channel 302 for flushing a liquid 304, for example water or alkali, into a chamber, not shown here, of the flushing box 300, for example a main washing, prewashing or flushing compartment. Similar to the above with reference to FIG. 2 described channel of the flushing channel 302 a reducer 306 for generating a cross-sectional constriction 308, by which the amount of liquid flowing through the Ein Hugheskanal 302 is reduced.
  • a flow direction of the liquid 304 is indicated by four horizontal arrows.
  • the reducer 306 is disposed between an inlet port 310 for introducing the liquid 304 and an outlet port 312.
  • the outlet port 312 serves to discharge the liquid 304, more specifically a reduced amount of liquid 314 through the reducer 306, into the chamber to flush it out.
  • the flushing channel 302 has a ventilation opening 316 for pressure equalization with an environment of the flushing channel 302. It is particularly advantageous if the ventilation opening 316, as in FIG. 3 shown, in the region of a flow shadow of the reducer 306, that is adjacent to one of the outlet opening 312 facing side of the reducer 306, is arranged. As a result, pressure fluctuations can be compensated reliably.
  • the dispenser box 300 has a peel water passage 320 for branching peeling water 322 located at one between the reducer 306 and the inlet port 310 arranged branch 324 branches off from the scavenging channel 302.
  • a cross section of the peeling water channel 320 is larger than a largest cross section of the flushing channel 302 and many times larger than the cross-sectional constriction 308.
  • the reducer 306 is placed in a portion of the flushing channel 302 that represents the largest cross section of the flushing channel 302.
  • the reducer 306 forms a wall portion of the peeling water channel 320.
  • the two channels 302, 320 in FIG. 3 oriented substantially perpendicular to each other.
  • the two channels 302, 320 may be aligned at any other angles to each other.
  • an Einsaug bin can be reduced.
  • the dispenser 300 is configured to scavenge chlorine bleach via a pre-wash compartment.
  • the cross-sectional constriction 308 is designed, for example, such that the amount of water introduced into the prewash compartment is reduced to 5 L / min.
  • the dispensing channel 302 is integrated, for example, in a cover of the dispenser box 300.
  • the ventilation opening 316 has the function of preventing uneven pressure conditions in the flushing passage 302 between the free flow path and the nozzles. For example, it is thus prevented that, depending on the pressure difference, once 5 L / min and once 7 L / min are passed into the prewash. Without the ventilation opening 316, water would be sucked in by a sporadically occurring negative pressure downstream of the reducer 306, which should actually be sheared off. If too much water gets into the prewash compartment, the prewash compartment overflows and the lye can flow out of the front of the washing machine. By introducing the ventilation opening 316 after the reducer 306, a resulting negative pressure is reliably prevented. So no additional water can be sucked.
  • the amount of water defined by the cross-sectional constriction 308 is constant. For example, it can be ensured that only a constant and reproducible predetermined amount of water, for example 5 L / min is introduced into the pre-wash and the pre-wash does not overflow to the front.
