Definitions

  • the invention relates to a spray device for distribution of washing-up liquid in a dishwasher.
  • a conventional dishwasher rotatable below an upper and lower crockery basket stored spray arms arranged. Are spaced on the spray arms spray nozzles distributed to each other, with which the Low-rinse liquid supplied in different directions is sprayed. At the same time, the recoil pulse of the sprayed rinsing liquid to the spray arms a pulse directed in the direction of rotation, which the Spray arms rotated.
  • the spray arms For supplying the rinsing liquid to the outside spray nozzles the spray arms have a minimum cross-section, and Distribution of the washing liquid in the interior of the dishwasher the length of the spray arms is approximately equal to the width or Depth of the dishwasher interior.
  • At least one is installed stationary Spray nozzle provided, which is a movably mounted spreader to distribute the sprayed from the spray nozzle Rinsing liquid is associated.
  • the spreader Due to the impulse of the rinsing liquid from the spray nozzle the spreader is set in motion and thereby distributed the rinsing liquid in different directions inside the dishwasher interior.
  • the spray jet from the spray nozzle can be aligned almost parallel or already as a conically expanded spray the spray nozzle. Through the spreading device Spray jet only redirected and / or additionally when redirecting be expanded.
  • the spray nozzle or several spray nozzles are used by the Circulation pump of the dishwasher with washing liquid applied.
  • Spray nozzles can be provided with conventional spray arms be also from the circulation pump with rinsing liquid be charged.
  • one Circulation pump are provided for the fixed Spray nozzles build up a higher flushing fluid pressure.
  • flushing liquid supply is a two-stage circulation pump, which is used for the conventional Spray arms the rinse liquid with low pressure and high Throughput and the flushing liquid for the fixed spray nozzles with high pressure and low throughput.
  • the spray device arranged on the ceiling of the dishwasher room By the spray device arranged on the ceiling will Washware in the upper crockery basket additionally and evenly charged with rinsing liquid, so that also from the top a good cleaning effect is achieved.
  • alternative can selectively flush the rinse liquid from the sprayer in a desired area of the interior of the dishwasher be sprayed.
  • the spray device in a corner of the ceiling this can be done in an upper basket Cutlery lying flat with a high-rinse liquid Pressure. By targeted blasting the cutlery becomes particularly soiled well relieved. Is the spray device e.g.
  • Spray jet from the spray device will spread the spray jet along the inside of the dishwasher, so that a wide distribution of the rinsing liquid is achieved.
  • two or more spray nozzles provided that also for more even distribution the rinsing liquid in a different direction blast away.
  • the Spreading device a rotatably mounted disc. Will the Washer set in motion by the rinsing liquid, see above becomes an even all-round distribution of the rinsing liquid reached.
  • the rotatable bearing is very simple to realize and against contamination or mechanical Loads very stable.
  • Deflection elements on the spreading device result in a deflection of the spray jet from the spray nozzle and thus one Even distribution of the washing liquid in the interior of the dishwasher reached.
  • the deflection elements with each other designed differently, so the spray jet deflected in a different direction by each deflecting element.
  • the Deflection elements designed like blades or turbine blades. This results in a particularly efficient redirection of the water jet from the spray nozzle (s).
  • the impulse transfer for example on the rotatably mounted Disc leads to a fast rotation and very even Distribution of the rinsing liquid over the area of the Dish rack.
  • the deflection elements are formed like a channel or as a hole in which the Rinsing liquid coming from the spray nozzle becomes.
  • the spray nozzle is turned on a rinsing liquid channel, e.g. a pipe socket and this on the back through a wall of the dishwasher interior plugged in.
  • the spreader stored on the flushing liquid channel, so for the Spreading device no further brackets or bearing elements on the inner wall of the dishwasher.
  • For the Spraying equipment is only a breakthrough in the inside of the dishwasher necessary and the seal simplified yourself.
  • the spatial and temporal variation of the in different Areas of the rinsing interior emitted amount of rinsing liquid is also adjustable in that the rinsing liquid at least two spray nozzles can be fed separately and thus an independent control of the amount of rinsing liquid enabled per spray nozzle.
  • Fig. 1 shows a schematic cross section through a Dishwasher interior 1 with an upper crockery basket 2 and a lower crockery basket 3 for storing items to be washed. There is an upper one below each of the baskets Spray arm 4 and a lower spray arm 5 are arranged. Approximately is in the middle of the ceiling of the dishwasher interior 1 Ceiling shower 6 installed. The ceiling shower 6 acts the items to be washed stored in the upper crockery basket 2 from above Rinsing liquid.
  • Rinsing liquid is collected in the dishwasher sump 7 from there sucked in by a circulation pump 8 and via a first line branch 9 the lower spray arm 5, via a second line branch 10 the upper spray arm 4 and one third line branch 11 of the ceiling shower 6 supplied.
  • a rotatably mounted lens 12 rotates Ceiling shower 6 and distributed spray jets 13 in different Directions and at different angles during the Rotation.
  • Fig. 2 shows the detailed view of the ceiling shower 6 with the Spreading disc 12 and a nozzle insert 14.
  • turbine blades 15 On the spreading disc 12 are turbine blades 15 at regular intervals arranged.
  • the height and the height profile of the turbine blades 15 is at least in part of the turbine blades designed differently.
  • the turbine blade 15.1 the maximum height on the inside H1 and is only slightly flattened in the outer area.
  • the height A1 of the outer area of the turbine blade is approximate 10% less than the maximum height H1.
  • the nozzle insert 14 has a rear end with a flexible hose of line branch 11 is connected and supplied by this with rinsing liquid.
  • the nozzle insert 14 is in from the back of the dishwasher inner wall this is inserted and lies with a flange 16 on the Inner wall of the dishwasher.
  • the front area of the nozzle insert 14 protrudes into the interior of the dishwasher.
  • the .Insert 14 is placed on the inside of the dishwasher 1 Ring nut 17 attached to the inside of the dishwasher, a sealing insert, not shown, on Flange 16 between the inner wall and the nozzle insert 14 seals.
  • a flushing liquid jet radiate. It borders on the nozzle ring 18 Shaft section 20 on which the lens 12 with the turbine blades 15 protruding from the top becomes.
  • the nozzle insert 14 is then by means of a second ring nut 21 secured to an externally threaded portion 22 of the nozzle insert 14 is screwed on.
  • Fig. 3 shows a second embodiment of a diffuser 30, in which channels 31 are formed, which are from the interior first run in the radial direction and to Outside a peripheral component in addition exhibit.
  • the lens 30 is with its bore 32nd pushed over the nozzle ring 18 of the nozzle insert 14 of FIG. 2, so that the spray of spray the nozzles 19 directly into the channels 31.
  • the entry pages the channels 31 are distributed in the inner area, that not all nozzles 19 through the sections at the same time blocked between the entry sides of the channels 31 become.
  • the axial course of the channels 31 each different and the channels occur at different heights on the edge of the Spreading disc 30. This creates a spatial radiation the rinsing liquid in different angular directions reached so that the washing liquid is also uniform distributed to the area of the upper basket 2 becomes.
  • not shown can part of the channels 31 on the underside of the lens 30 emerge, so that the washing liquid on the Area directed immediately below the ceiling shower 6 becomes.
