Definitions

  • the invention relates to a dishwasher for commercial purposes, in particular for washing flat items such as baking trays, trays or the like, according to the preamble of claim 1.
  • Such dishwashers have a washing compartment in which the soiled items are arranged.
  • there is at least one wash tube or spray arm below the wash cabinet which is arranged to be fixed or movable.
  • spray arms have already been arranged in the upper area of the wash cabinet.
  • rotating spray arms are provided.
  • the rotational movement is driven by inclined nozzles via the recoil of wash liquor sprayed with the appropriate pressure.
  • the rotation of the two spray arms can not be coordinated.
  • the individual rays can interfere with each other.
  • the cleaning effect of a water or wash liquor jet is based on the one hand on the mechanical effect when the jet hits the wash ware with comparatively high pressure.
  • a certain time must be available in which the water or the wash liquor can run off.
  • the rotation takes place in an uncontrolled manner, whereby the two phases described are mutually disturbed.
  • rotating spray arms only allow incomplete use of the washing area.
  • fixed wash pipes are attached to the top and bottom of the wash cabinet, which are moved back and forth in a linear movement, fixed to one another, within the wash cabinet.
  • the wash pipe nozzles are aligned vertically.
  • this has the disadvantage that upper and lower rinse jets meet directly and, under certain circumstances, cancel each other out, so that the mechanical action on the wash ware is adversely affected.
  • the so-called contact time i.e. the time in which the wash ware in the wash cabinet is actually processed with wash jets is considerably reduced. In order to achieve sufficient washing results with such a device, long washing times are therefore necessary. This, in turn, is undesirable in the commercial field of application, since the aim is to keep the wash cycles as short as possible.
  • a dishwasher has become known in which a plurality of washing pipes are fixedly arranged above and below and on the side walls of the washing compartment. These wash tubes are supplied with wash liquor via at least two wash liquor pumps.
  • a control ensures that different washing pipes are used alternately, so that on the one hand a good use of space in the washing area is ensured and on the other hand opposing washing jets do not interfere with each other.
  • Such a dishwasher does achieve very good washing results, However, due to the complex structure, it is very expensive to manufacture. A complex pump control and an extremely large number of nozzles must be provided.
  • CH 447 499 has also made a dishwasher known primarily for pots or the like.
  • In the upper area of the wash cabinet there are fixed wash pipes with wash jets directed vertically downwards.
  • In the lower area of the wash cabinet several wash pipes are arranged, which can be rotated about their longitudinal axis. They are simultaneously pivoted back and forth about their longitudinal axis via a lever drive device.
  • the rinsing jets emerging from the nozzles of the washing pipes run off the inside of the pot-shaped items to be washed. Since the underside of pots or the like is often heavily soiled, the lower washing pipes are subjected to higher pressure, so that a hold-down device is additionally provided to hold the pots in position.
  • Such a device is indeed suitable for container-like wash ware, but delivers poorer results for flat wash ware, such as baking trays or trays.
  • flat wash ware such as baking trays or trays.
  • the object of the invention is therefore to propose a dishwasher for commercial purposes, in particular for flat items such as baking trays, trays or the like, in which a good washing result by a high mechanical action of the washing jets on the items to be washed and by sufficient flow time for removal of the loosened dirt is guaranteed with long contact times. Furthermore, a good use of space should be ensured and in particular the spray shadows mentioned above should be avoided.
  • Dishwasher on top washing tubes which are rotatable at least about their longitudinal axis and which can be pivoted back and forth via an upper drive device.
  • Such an arrangement can be used to clean, in particular, large items to be washed in shorter washing times. Since both the upper and the lower wash tubes swivel back and forth, there is no spray shadow in the items to be washed, for example behind a peripheral edge of a baking sheet or tray that cannot be reached by the wash jets. Because these jets are generated from above and from below, the upper areas are also scanned by considerably shorter and thus less diverging rinsing jets than would be the case with rinsing jets generated only below. This results in a high mechanical impact.
  • the proposed arrangement is energy-saving and effective, because with only one pump system and comparatively few nozzles, optimal space utilization and a long contact time are achieved.
  • control of the upper and lower wash pipes can also be advantageous, in which the upper and lower wash pipes are pivoted in opposite directions, so that the upper and lower wash jets always meet.
  • This type of control offers an advantage especially when it is not necessary to wash flat, container-shaped items.
  • the upper wash jets then act as a stabilizer for the wash ware, which is cleaned on its lower side by the lower wash jets.
  • the possibly high pressure of the lower wash jets would possibly be able to lift pots, bowls, etc. out of their rinsing position without the stabilization mentioned.
  • all the washing pipes are arranged parallel to one another. This simplifies the coordination of the respective pivoting movements.
  • the brackets for the Items to be washed are arranged so that, in the case of flat items to be washed, the area to be washed lies transversely to the washing pipes. In this way, the surface to be rinsed is swept in a wiper-like movement by means of the pivoting movement of the individual washing pipes and thus cleaned over the entire surface.
  • the wiper-like swiveling movement of the rinse jet repeatedly results in areas in which the mechanical action of the rinse jet is used to loosen the dirt, while in other areas the outflowing rinse water or the outflowing rinse liquor transports the loosened dirt downward.
  • the nozzles are preferably arranged on the individual washing pipes in such a way that they are arranged exactly in the spaces between the individual flat items to be washed. As a result, each flat wash item is gripped and rinsed by a nozzle of each wash tube.
  • these nozzles are further arranged inclined in the washing pipe with respect to the washing pipe axis so that they are at an acute angle, preferably at least 5 °, on the surface to be mainly cleaned, e.g. the inner bottom surface of a baking sheet or tray, any flat washware hits. Since flat wash items such as baking trays, trays or the like generally have a particularly dirty side, this is preferably cleaned by the inclined nozzles.
  • the rinse jets meet here at the acute angle mentioned above, which improves the mechanical action mentioned.
  • So-called flat jet nozzles are advantageously used.
  • a large area of the items to be washed can be sprayed by means of such nozzles, the nozzle cross section being kept small.
  • a small nozzle cross-section in turn ensures high pressure with which a "hard” jet is sprayed concentrated out of the washing pipe.
  • a high pressure when the steel hits the wash ware, in turn has a high mechanical effect to loosen the dirt located there.
  • the surface of the flat jet is advantageously aligned parallel to the wash tube axis. In this way, all areas that are hit by a washing nozzle are located in a plane that runs through the axis of rotation of the washing pipe. In this way, the angle setting of the washing pipes can be better determined for optimal use of space in the wash cabinet.
  • the drive for a plurality of washing pipes is advantageously coupled to one another, a simple but reliable possibility of such a drive being a lever drive in which a rotary lever of each washing pipe is articulated in a push rod. Due to the back and forth movement of such a push rod, which can be effected, for example, by means of an eccentric drive, all of the washing pipes articulated on a push rod are pivoted back and forth synchronously.
  • the dishwasher 1 according to FIG. 1 comprises a washing compartment 2, in which flat items 3 such as baking trays, trays or the like are lined up one behind the other. Dashed lines show washware holders 4 which engage behind the edge 5 of the flat washware 3 and rest on the floor 6. On the lower edge 7, each wash ware is supported on the adjacent wash ware holder 4.
  • the washing pipe 8 On its underside, the washing pipe 8 is equipped with a series of washing nozzles 11, which are designed as flat jet nozzles, as indicated by the dash-dotted angles at the outlet of the nozzles 11.
  • a lower washing pipe 12 At the bottom of the washing compartment 2 there is a lower washing pipe 12, which, like the upper washing pipe 8, is rotatably supported at its ends 13, 14 and has washing nozzles 15, which, however, are arranged on the lower washing pipe 12 on its upper side.
  • the nozzles 11 of the upper washing tube 8 are at an angle ⁇ in the direction of the items to be washed 3 inclined.
  • the lower nozzles 15 are also inclined at an angle ⁇ in the direction of the items 3 to be washed.
  • the angles ⁇ and ⁇ are dimensioned such that the rinsing jets of the washing nozzles 11, 15 strike the bottom 6 at an acute angle.
  • a pump 16 is connected to the washing compartment 2 via a return 17.
  • a pressure line 18 branches into two horizontal pressure pipes 19, 20, each of which is connected to a row of upper 8 and lower 12 washing pipes.
  • a plurality of upper washing pipes 8 are articulated to a push rod 22 via a lever 21.
  • the push rod 22 is in turn articulated on two pivot levers 23, 24, the pivot axes 25, 26 of which are located approximately at the level of the pivot tube axes 27.
  • the pivot lever 24 is designed as an angled double lever, which in turn is articulated on a vertical push rod 27 at its upper end 28.
  • a drive rod 30 is articulated, which is rotatably attached to an eccentric disc 31 at the output of a gear 32.
  • the gear 32 is in a non-positive connection with a motor 33.
  • the lower washing pipes 12 are also articulated via a lever 34 to a lower push rod 35, which in turn is articulated at its ends 36, 37 to two pivot levers 38, 39.
  • the pivot lever 38 is also designed as an angled double lever which is articulated at its free end 40 to the vertical push rod 27 and to the drive rod 30.
  • the two outer edge pipes 41, 42 are arranged rotated relative to the other upper washing pipes 8.
  • edge washing jets 45, 46 which do not flow out of the edge washing nozzles 43, 44 run parallel to the remaining rinsing jets 47 of the inner washing pipes 8.
  • the lower edge wash pipes 48, 49 are also rotated relative to the other lower wash pipes 12, so that the lower edge wash jets 50, 51 also do not run parallel to the other wash jets 52.
  • All wash pipes 8, 12, 41, 42, 48, 49 move in the pivoting movement from a certain angle section above the items to be washed. Since the individual washing nozzles 11, 15, 43, 44 are designed as flat jet nozzles, they sweep over the items to be washed 3 over their entire height H. At every point in the items to be washed 3 there are processing intervals in which dirt is either mechanically loosened by the impinging jet or else the loosened dirt can run off with the wash water or the wash liquor.
  • the space utilization is further improved by the twisted edge washing pipes 41, 42, 48, 49.
  • These edge washing pipes avoid that they only spray the wall of the wash cabinet in their one extreme position. In their other extreme position, the twist enables them to spray the dishes 3 over a larger diagonal distance.
  • the rotation of the edge wash tubes results in zones S, S 'where their rays 51, 50 intersect with the rays 52 of adjacent wash tubes 12.
  • these cutting areas S, S ' are located in zones far away from the washing pipes 49, 12, where the mechanical action of individual jets diminishes due to the great distance. In the cutting areas S, S ', which represent the most distant distance for the respective washing pipes 12, 48, 49, there is an additional benefit from the mutual reinforcement.
  • 3 and 4 show special exemplary embodiments for a useful coordinated pivoting movement of the upper 8 and lower 12 washing pipes.
  • This type of washing pipe control is particularly advantageous if not only flat washware 3, but possibly also pots or other container-shaped washware is to be washed.
  • the upper washing tubes 8, with their washing jets 47 have a stabilizing effect on the container-shaped items to be washed (not shown), which is inserted into the dishwasher 1 with its opening facing down.
  • the lower washing tubes 12 with their rinsing jets 52 can therefore be started at high pressure without the dishes being lifted.
  • a washing pipe control system is shown, which could be called a parallel control system.
  • the upper 8 and lower 15 wash pipes swivel in the same direction of rotation.
  • the rinse jets 47, 52 of the upper 8 and lower 12 wash pipes always run parallel. They only interfere with one another in the short time when they pass each other. Most of the time and thus also in the area of the largest area that they run on the items 3 to be washed, they are undisturbed by one another.
  • Each rinse jet 47, 52 is able to develop its full cleaning power undisturbed over the entire height H of the wash ware.
  • the invention is not limited to the two illustrated exemplary embodiments of the washing pipe control.
  • solutions are also conceivable in which the individual lower washing pipes 12 or the individual upper washing pipes 8 are at least partially decoupled from one another in their drive.
  • the individual lower washing pipes 12 or the individual upper washing pipes 8 are at least partially decoupled from one another in their drive.
