Definitions

  • the present invention relates to a household dishwasher.
  • a dishwasher can have a wash tub and spray devices arranged in the wash tub, such as a roof-mounted sprayer or rotatably mounted spray arms, for spraying items to be washed with washing liquid and/or fresh water.
  • spray devices arranged in the wash tub, such as a roof-mounted sprayer or rotatably mounted spray arms, for spraying items to be washed with washing liquid and/or fresh water.
  • the EP 3 254 600 A1 The figure shows a dishwasher with a wash tub and a spray arm rotatably mounted on the tub.
  • the spray arm comprises a multitude of spray nozzles, to which the wash fluid is supplied by means of flow guide elements.
  • the EP 2 397 060 A2 describes a dishwasher with a spray device comprising a deflector designed to deflect the wash liquor directed onto it in order to create a variable spray pattern.
  • a washing jet nozzle for dishwashers is known with a somewhat rotationally symmetrical nozzle hollow body, wherein the nozzle hollow body is formed from a hollow cylinder provided with a bottom on one side and two hollow truncated cones standing with their tips on each other.
  • the DE 198 41 355 A1 describes a dishwasher with a spray arm and a spray nozzle arranged on it, wherein the washing liquid is supplied to the spray nozzle in a circulating motion.
  • a cleaning water jet device which is designed in such a way that it rotates a nozzle arranged in a chamber by means of a liquid pressure in such a way that the liquid jet ejected from the nozzle forms a conical shape around a central axis of the chamber opening.
  • one object of the invention is to provide an improved household dishwasher.
  • the household dishwasher comprises a wash tub and at least one spray device arranged within the wash tub for spraying wash liquor and/or fresh water into the wash tub.
  • the spray device includes a nozzle for spraying the wash liquor and/or fresh water and a spiral flow guide element for directing the wash liquor and/or fresh water to the nozzle.
  • the spiral flow guide element is configured to supply the wash liquor and/or fresh water to the nozzle during operation of the spray device in such a way that the wash liquor and/or fresh water exits the nozzle as a rotating conical spray jet.
  • the wash water and/or fresh water exits the nozzle as a rotating cone spray jet the items in the wash tub are particularly well wetted by the wash water and/or fresh water, as a chaotic spray pattern is created. This improves the cleaning performance of the household dishwasher.
  • the spray device can be, for example, fixed to the washing tank, mounted on a spray arm rotatably within the washing tank, or attached to a dishware holder within the washing tank.
  • the spray device can also be located on the bottom or top of the washing tank.
  • a plurality of spray devices are provided.
  • a "conical spray jet” is understood to be a spray jet with a conical surface.
  • the conical spray jet exits the nozzle at a defined angle.
  • the phrase "rotating" the conical spray jet in this context, specifically means that the conical spray jet rotates around an axis of rotation as it exits the nozzle.
  • the spiral flow guide element is designed in the form of an Archimedean spiral or in the form of a logarithmic spiral.
  • a left-handed or a right-handed spiral geometry can be selected.
  • left-handed specifically refers to a counterclockwise rotation.
  • clockwise refers to the direction of rotation of the spiral flow guide element.
  • Counterclockwise in this context means, in particular, that the spiral flow guide element winds clockwise.
  • counterclockwise can also be replaced by the terms “left-handed” or “curved to the left.”
  • clockwise can be replaced by the terms “right-handed” or “curved to the right.”
  • the direction of curvature of the spiral flow guide element is thus synonymous with the degree of clockwise rotation of the spiral flow guide element.
  • the previously mentioned exit angle of the conical spray jet from the nozzle can be influenced by changing the distance of a wall of the spiral flow guide element from the center point of the respective nozzle.
  • the distance from the center point of a logarithmic spiral changes by the same factor with each revolution. If this factor is chosen to be very small, the exit angle can be reduced. Conversely, the exit angle can be increased if the factor is increased.
  • the distance can be varied by appropriately increasing or decreasing the spiral radius.
  • the spray device has a rotatably mounted centrifugal element which, during operation of the spray device, can be subjected to the rinsing liquor and/or fresh water in order to set the centrifugal element in rotation.
  • the centrifugal element can be exposed to the cleaning solution and/or fresh water
  • the centrifugal element is exposed to the cleaning solution and/or fresh water during operation of the spray device, causing it to rotate around an axis of rotation. Because the cleaning solution and/or fresh water exits the nozzle as a rotating conical spray jet, the driving torque acting on the centrifugal element can be increased, as the conical spray jet impacts not only a hub but also the impeller blades of the centrifugal element.
  • the gyratory element has impeller blades, wherein a curvature direction of the impeller blades coincides with a curvature direction of the spiral flow element.
  • the spiral flow guide element also has a left-handed curvature, or is left-handed. If the impeller blades are curved to the right, the spiral flow guide element also has a right-handed curvature, or is right-handed. These identical curvature directions allow for a further increase in the drive torque acting on the gyratory element, thus improving the spray pattern.
  • the gyroscope element is received in a cage and rotatably mounted in it.
  • the cage preferably has several interconnected struts that are connected to a housing of the spraying device, for example by snapping or locking them in place.
  • the struts meet at a connecting section that has a bore in which the hub of the gyratory element is rotatably mounted.
  • the household dishwasher further comprises an intensive zone which has several spray devices.
  • intensive spray zones are provided. These intensive zones can, for example, be attached to the dish racks of a household dishwasher. Each intensive zone might, for instance, have three such spray devices. However, the number of spray devices is arbitrary.
  • the intensive zone has a valve to move the intensive zone from an active state to an inactive state and vice versa.
  • the valve is a manually operated valve.
  • the valve can have a valve body that is linearly displaceable to move the spray device from the active state to the inactive state and vice versa.
  • the intensive zone has a housing on or in which the spiral flow-guiding elements are integrally formed.
  • the housing is a plastic component.
  • the housing can, for example, have a base and a lid that are firmly connected to each other.
  • the spiral flow guide elements of the spray devices are molded onto the lid.
  • the household dishwasher further comprises a spray arm rotatably mounted in the washing tub, which has several spray devices.
  • multiple spray arms can be provided.
  • the spray arms are located, for example, at the dish holders, on the ceiling of the wash tank, or on the bottom of the wash tank.
  • the spiral flow guide elements of adjacent spray devices have different directions of curvature.
  • the spray devices are arranged such that a right-hand spiral flow guide element is positioned between two left-hand spiral flow guide elements, and vice versa. This further improves the wetting effect.
  • the spiral flow guide elements can also have identical directions of curvature.

  • each dishware holder 12 to 14 can be pushed or moved into the washing container 2 in an insertion direction E and pulled or moved out of the washing container 2 in an extension direction A opposite to the insertion direction E.
  • the Fig. 2 shows a schematic overview of an intensive care zone 15.
  • Fig. 3 shows a schematic underside view of intensive care zone 15 and the Fig. 4 shows a schematic cross-sectional view of the intensive care zone according to section line IV-IV of the Fig. 2
