Definitions

  • the invention relates to a dishwasher with at least one dish rack and a device for washing dishes in the dishwasher, wherein at least one dish rack at least two sprayers are assigned for certain areas, and wowbei the device control means for individually controlling the at least two sprayers a dish rack during the Rinsing has.
  • a dish rack for dishwashers which provides in the storage area tubes, which are each provided with openings to pressurize the washware located immediately above it.
  • rinse liquid passes through all the outbreaks formed in the pipes of the dish rack formed as an inflow line. Due to the narrow inlet pipes, a significant pressure drop occurs up to the farthest point from the inflow of the pipes. Due to this, the rinsing or spraying performance is not formed in the same way in all areas of the crockery basket, so that in areas which are farthest from the inflow, the spray jet impinges on the items to be washed at a lower speed.
  • a dishwasher is known with an upper and a lower dish rack, wherein in the lower dish basket heavily soiled dishes, such as pots are placed, while in the upper dish sensitive items such as glasses are arranged.
  • the dishwasher further comprises a control device with which it is possible, if necessary, to clean the dishes arranged in the lower dish rack of intensive cleaning by increasing the spray jet pressure.
  • a dishwashing machine in which heavily soiled dishes are provided for cleaning, to achieve an intensive cleaning with increased spray jet pressure in that by means of a control device, the number of nozzles used is reduced and the individual nozzles are driven in succession.
  • the dishwashers From the DE 41 13 8 87 A1 and DE 2 304 035 the dishwashers are known, which have an upper and lower spray arm, wherein control means are provided for controlling the upper and lower spray arm.
  • the object of the present invention is therefore to provide a dishwasher, which makes it possible to optimally clean dishes arranged in a dish rack with different soiling according to the degree of soiling.
  • At least one dish rack is assigned at least two spraying devices for certain areas, wherein one device has a control device for individually activating the at least two spraying devices of a dish rack during flushing.
  • the spraying devices are arranged below the dish rack and preferably each consist of rotating spray arms.
  • the at least two spraying devices are subdivided into individual areas, preferably quadrants, which can be shut off in each case via a blocking means in relation to the other areas, so that the control device can specifically control the rinsing fluid for controlling certain areas in individual areas, thus waving dishes with more persistent Grout can be applied more intensively with rinsing liquid, while other areas, which are equipped, for example, only with glasses, learn less intensive spray treatment.
  • the sprayers are formed from rotating spray arms, with a rotating spray arm arranged in each particular area.
  • the areas are square.
  • the selectable areas are formed separable from each other via a shut-off.
  • the consumption values in particular the water and energy consumption values for the respective rinsing programs, are optimized, i. Water consumption or energy consumption on average decreases.
  • the device can be used both in household and commercial dishwashers use, as well as in these respective devices both in the upper and lower basket and each separately used in a single dish rack.
  • FIG. 1 is a schematic representation of a dish rack 1 with designed as a rotatable spray arms spraying 2a - 2d, wherein the spray arms 2a - 2d open in each case separately in the blocking means 3.
  • the spray arms 2a - 2d are arranged below the dish rack 1.
  • the inlet region to the shut-off means 3 is brought together in the direction of the circulating pump 6, so that a central region is formed, from which the respective inflow regions into the spraying arms 2a-2d via the shut-off means 3 takes place.
  • this blocking means 3 is designed as a solenoid valve.
  • the regions are formed in the embodiment shown as quadrants, wherein in the center of each quadrant of the pivot point of a spray arm 2a - 2d is arranged.
  • Each of the individual specific areas is formed shut-off means 3 with respect to the other areas lockable.
  • the blocking means 3 are controlled via the control device 4, which in turn is connected to the control device (not shown or integrated therein) of the dishwasher, wherein the respective Anêtrhythmen are stored in a control program, which control the wash programs.
  • the control device 4 is connected to a control element 5, which has a schematic representation of the spray device regions 2a-2d and advantageously displays the respectively selected regions via light elements.
  • a keypad with four buttons is provided on a control panel of the control element 5, which reflect the respective quadrants, which are provided for a more intensive wash program.
  • the user can, if the selection is made manually, by pressing the appropriate buttons, select an area that is to be rinsed more intense.
  • the method is optional to choose, or provided in certain washing programs.
  • FIG. 2 the device is shown in a schematic side view, with a dish rack 1 and two spray arms 2c and 2d.
  • the respective spray arms 2a to 2d are selectively controlled, wherein each spray arm has a limited range, which can be reliably applied with rinsing liquid.
  • the spray intensity for example, by changing the speed control of the Um Georgzpumpenmotors, and thus the exit velocity of the spray can be adjusted according to the respective requirements.
  • the range selection manually by the user via the control panel it is also possible to detect by mounted in the rinse container sensors, for example by a camera, items with particularly stubborn soiling and then manually select respective areas or automatically select that should undergo more intensive cleaning during the wash program.
  • ware with stubborn soiling can be applied more intensively with rinsing liquid, while other areas, which are for example only equipped with glasses, experience a less intensive spray treatment, whereby a device is provided, which makes it possible in a dish rack. 1 arranged items to be cleaned with different soiling according to the degree of soiling optimal.
  • the consumption values in particular the water and energy consumption values are optimized for the respective rinsing programs, i. Water consumption or energy consumption on average decreases.
