Definitions

  • the present invention relates to a household dishwasher.
  • a dishwasher can have a washing container and spray devices arranged in the washing container for spraying items to be washed with washing liquid and/or fresh water.
  • a spray device in particular as a so-called roof gyroscope, can be mounted on a ceiling of the washing container.
  • the WO 2008/125474 A1 describes a dishwasher with a hydraulic system and at least one roof spray device arranged above a dish rack, which can be supplied with washing liquid by means of the hydraulic system and which has a rotatable spray head which is attached to the hydraulic system by means of a cage.
  • the spray head is rotatably mounted in the cage.
  • the EP 1 232 720 A2 describes a spray device for distributing washing liquid in a dishwasher.
  • the spray device has at least one stationary spray nozzle and at least one movably mounted scattering device associated with the spray nozzle.
  • the JP 2004 236963 A describes a spray device for a dishwasher.
  • the spray device comprises a spray head which is rotatably mounted on a supply line and which is set in rotation by means of a nozzle provided on the supply line.
  • the US 2015/0366430 A1 shows a device for rinsing glasses or bottles placed over a rotating element.
  • the US 1,916,806 A discloses a steam-operated dishwasher in which water and steam are distributed by a rotary element.
  • one object of the invention is to provide an improved household dishwasher.
  • the domestic dishwasher comprises a washing container and at least one spray device arranged inside the washing container for spraying washing solution and/or fresh water in the washing container, wherein the spray device comprises a cage, a rotary element rotatably mounted in the cage and a supply line with a nozzle for supplying the washing solution and/or the fresh water to the rotary element.
  • the rotary element In its operating position, which it assumes at least when washing solution and/or fresh water is supplied to it, the rotary element is raised with respect to a direction of gravity and set in a rotational movement and arranged completely above the nozzle.
  • the rotary element comprises a hub and rotor blades connected to the hub, wherein the hub is designed to supply the washing solution and/or the fresh water supplied to the hub with the aid of the supply line to the rotor blades during operation of the domestic dishwasher.
  • the spray device can be used to spray the washware holders arranged in the washing container or the washware held in the washware holders from below. This achieves improved cleaning performance.
  • the washing solution and/or the fresh water can be distributed in the washing container, in particular in the form of a hemispherical spray pattern. The rotatable mounting of the rotary element thus further improves the cleaning performance.
  • the gyro element is arranged completely above the nozzle in its operating position, which is to be understood as meaning that all elements and/or areas of the gyro element are arranged above the nozzle with respect to the direction of gravity.
  • a clear dimension is created between the nozzle and the gyro element at every point, which allows dirt particles to pass through and thus counteracts a failure or malfunction due to contamination.
  • the clear dimension refers to the width and/or height of a gap that arises between two adjacent parts of the nozzle on the one hand and the gyro element on the other.
  • the clear dimension between the nozzle and the gyro element in the operating position of the gyro element is at least 3 mm, preferably at least 4 mm and particularly preferably at least 5 mm.
  • the spray device is thus designed to be resistant to contamination.
  • the gyro element is arranged inside the cage and mounted thereon.
  • the nozzle is designed to spray the rinsing solution and/or the fresh water against the direction of gravity under pressure onto the gyro element.
  • the rinsing solution and/or the fresh water is sprayed against the direction of gravity onto the gyro element using the nozzle, which is then raised into its operating position against the direction of gravity and set in a rotational movement. This distributes the rinsing solution in the washing container.
  • the spray device can, for example, be fixedly attached to the washing container or to a dishware holder accommodated in the washing container.
  • the spray device can be provided on a base of the washing container.
  • the spray device can also be arranged on a spray arm rotatably mounted on or in the washing container.
  • a plurality of spray devices are provided.

  • Embodiments are also possible in which the rotary element is already arranged in its operating position without the influence of the sprayed-on rinsing solution and/or the fresh water. This can be achieved by a corresponding structural design.
  • Embodiments in which the rotary element is only raised into its operating position by the influence of the sprayed-on rinsing solution and/or the fresh water have the advantage of a particularly simple construction and a further improved possibility of cleaning, in particular the bearing points, in the rest position.
  • exactly one nozzle is provided which is designed to spray the rinsing liquid and/or the fresh water centrally onto the rotary element.
  • the nozzle can be provided centrally below the gyro element.
  • the nozzle can be arranged centrally with respect to a rotation axis of the gyro element.
  • the nozzle can also be positioned offset to the gyro element or to the rotation axis.
  • the nozzle is implemented by providing a cross-sectional constriction on the supply line. This means that the nozzle represents a cross-sectional constriction on the supply line. This can increase the pressure of the rinsing solution and/or the fresh water sprayed with the help of the nozzle.
  • the gyro element has a curved, in particular spherical cap-shaped, outer contour.
  • the outer contour is preferably provided on the rotor blades of the gyro element.
  • the spherical cap-shaped outer contour is formed when the gyro element rotates about its axis of rotation. This means that the outer contour is an envelope, in particular an enveloping surface, preferably a three-dimensional envelope curve, of the rotating gyro element.
  • a spherical cap, a spherical segment or a spherical section is part of a spherical body that is formed by a section with a plane.
  • Such a spherical cap has the shape of a dome and has a circular disk as its base.
  • the cage is curved, in particular curved in the shape of a spherical cap.
  • the cage is designed to correspond to the gyro element. This results in a particularly compact installation space for the spray device.

  • the hub and the rotor blades are preferably made of one piece material.
  • the rotor element is preferably a one-piece plastic component, in particular a plastic injection-molded component. With the help of the rotor blades, the rotor element is set in rotation by spraying the rinsing solution and/or the fresh water onto the hub. This distributes the rinsing solution and/or the fresh water around the spray device. This results in a spherical spray pattern in particular, which improves the cleaning performance.
  • the hub is rotationally symmetrical to a rotation axis of the gyro element and has a conical outer surface.
  • the hub preferably does not have a truncated cone geometry, but rather a conical geometry with a conical tip or point.
