Definitions

  • the invention relates to a device for washing dishes in a dishwasher with at least one dish rack.
  • a crockery basket for dishwashers which provides tubes in the storage area, each of which is provided with openings in order to apply a washing liquid to the wash ware immediately above.
  • rinsing liquid passes through all the cutouts formed in the tubes of the crockery basket designed as an inflow line.
  • the narrow inflow pipes result in a significant pressure drop to the farthest point from the inflow of the pipes. Because of this, the washing or spraying performance is not designed equally in all areas of the crockery basket, so that in areas that are furthest away from the inflow, the spray jet hits the items to be washed at a lower speed.
  • the object of the present invention is therefore to provide a device which makes it possible to optimally clean items to be washed arranged in a dish rack with different soiling in accordance with the degree of soiling.
  • the device according to the invention for washing items to be washed in a dishwasher with at least one dish rack
  • at least one Dish rack assigned to at least two spray devices for specific areas and the device has a control device for individually controlling the at least two spray devices of a dish rack during washing.
  • the spray devices are preferably arranged below the crockery basket and each consist of rotating spray arms.
  • the at least two spray devices can be subdivided into individual areas, preferably quadrants, each of which is designed to be shut off from the other areas by means of a shut-off means, so that the control device for controlling certain areas can specifically control the washing liquid into individual areas, thereby washing items with stubborn stains, rinsing liquid can be applied more intensively, while other areas, which are only equipped with glasses, for example, receive a less intensive spray treatment.
  • the spray devices are formed from rotating spray arms, with a rotating or rotatable spray arm being arranged in each specific area.
  • the regions are preferably square.
  • the selectable areas are expediently designed to be separable from one another by a shut-off means.
  • the device according to the invention advantageously ensures that the consumption values, in particular the water and energy consumption values, are optimized for the respective washing programs, i.e. water consumption and energy consumption decrease on average.
  • the device according to the invention can be used both in household and commercial dishwashers, and can be used in these respective devices both in the upper and lower basket and in each case separately with only one dish basket.
  • the device according to the invention is explained in more detail below with reference to drawings using an exemplary embodiment. Show it:
  • Figure 1 is a schematic plan view of the device according to the invention and Figure 2 is a schematic side view of the device according to the invention.
  • a crockery basket 1 with spray devices 2a - 2d designed as rotatable spray arms is shown in a schematic representation, the spray arms 2a - 2d each opening into shut-off means 3 in a separate manner.
  • the spray arms 2a - 2d are arranged below the crockery basket 1.
  • the inlet area to the shut-off means 3 is brought together in the direction of the circulating pump 6, so that a central area is formed from which the respective inflow areas into the spray arms 2a-2d take place above the shut-off means 3.
  • this shut-off means 3 is designed as a solenoid valve.
  • the regions are designed as quadrants, the center of rotation of a spray arm 2a-2d being arranged in the center of each quadrant.
  • Each of the individual specific areas is designed to be shut off from the other areas by means of shutoff means 3.
  • the shut-off 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, the respective control rhythms being stored in a control program which control the washing programs.
  • the control device 4 is connected to an operating element 5, which has a schematic representation of the spray device areas 2a - 2d and advantageously displays the respectively selected areas via lighting elements.
  • a keypad with four keys is provided on an operating panel of the operating element 5, which keys are the respective quadrants for a more intensive washing program are provided, reflect.
  • the user can, if the selection is made manually, by pressing the corresponding buttons, select an area that is to be rinsed more intensively.
  • the method is expediently to be chosen optionally or is provided in certain washing programs.
  • the inventive device is shown in a schematic side view, with a crockery basket 1 and two spray arms 2c and 2d.
  • the respective spray arms 2a to 2d are controlled in a targeted manner, each spray arm having a limited area which can be reliably acted upon with flushing liquid.
  • the spray jet intensity for example by changing the speed control of the circulating pump motor, and thus the exit speed of the spray jet can be adapted according to the respective requirements.
  • the area selection manually by the user via the control panel it is also possible according to the invention to identify items to be washed with particularly stubborn soiling by sensors mounted in the washing compartment, for example by means of a camera, and then to select or have respective areas selected manually or automatically that should experience more intensive cleaning during the washing program.
  • washware with stubborn staining can be subjected to more intensive washing liquid, while other areas, which are only equipped with glasses, for example, receive a less intensive spray treatment, thus providing a device which makes it possible to place them in a crockery basket 1 optimally cleaned dishes with different soiling according to the degree of soiling.
  • the device according to the invention advantageously ensures that the consumption values, in particular the water and energy consumption values, are optimized for the respective washing programs, i.e. water consumption and energy consumption decrease on average.
