Definitions

  • the present invention relates to a household dishwasher.
  • a dishwasher includes a washing container in which items to be cleaned can be accommodated. Furthermore, such a dishwasher has at least one washware holder that can be moved out of the washing container and moved back into it.
  • the washware holder is suitable for holding washware which is subjected to washing liquor and/or fresh water using a rotatably mounted spray arm in order to clean the washware. If the washware holder is loaded carelessly by a user, this can result in the washware blocking the spray arm. In order to detect such a blockage, it is possible, for example, for the user to manually turn the spray arm. However, this is time consuming. In addition, there is also a risk that the user will contaminate clothing or their hands. It is therefore desirable to be able to easily detect such a possible blockage in order to be able to take appropriate countermeasures.
  • the WO 2013/064394 A1 describes a dishwasher with a washing container and a washware holder accommodated in the washing container.
  • a rotatable spray arm is provided below the washware holder.
  • the washware holder is grid-shaped and made up of a large number of interconnected wires.
  • the washware holder has at least one wire, which is oriented vertically from a bottom of the washware holder in the direction of the spray arm. When the washware holder is moved into the washing container, this wire abuts the spray arm, causing the spray arm to rotate. It is therefore easy for the user to see whether the rotating spray arm collides with the items to be washed in the washware holder or not. In the event that a collision occurs or is to be expected, the items to be washed can then be rearranged accordingly so that a collision of the items to be washed with the spray arm is avoided.
  • the WO 2021/078718 A1 shows a dishwasher with a housing, a washing chamber provided in the housing in which a washing process is carried out, at least one washing basket arranged in the washing chamber for loading with something to be washed. rinsing dishes and at least one spray arm that rotates around itself and introduces water into the washing chamber to wash the dishes.
  • the dishwasher further comprises a control mechanism which is designed to convert a sliding movement of the at least one washing basket into a rotation of the at least one spray arm.
  • an object of the present invention is to provide an improved domestic dishwasher.
  • a household dishwasher with a washing container, a washware receptacle for holding items to be washed, the washware receptacle being displaceable out of the washing container in an extension direction and displaceable into the washing container in an insertion direction oriented opposite to the pull-out direction, a spray arm rotatably mounted on the washware receptacle Applying washing liquor and/or fresh water to the items to be washed and a spray arm rotating device attached to the items to be washed is proposed, the spray arm rotating device having a movement element which is displaceably mounted on the items to be washed and which is supported in or on the washing container when the items to be washed are moved in the direction of insertion into the washing container to make the spray arm rotate.
  • the spray arm rotating device is provided and sets the spray arm in rotation, it is possible to easily recognize when moving the washware holder into the washing container whether there is a risk of the spray arm being blocked by the washware or not. It is unnecessary for a user to reach directly into the washing container in order to move the washing container manually. This simplifies the operability and increases the comfort of using the household dishwasher.
  • the flushing container is preferably cuboid or box-shaped.
  • a door is preferably pivotably attached to the washing container.
  • the washing container and the door together enclose a washing compartment of the household dishwasher. This washing compartment is delimited or enclosed by the washing container and the door attached to the washing container.
  • the washing container and the door therefore determine the boundaries or the spatial extent of the washing area.
  • the rinsing container preferably comprises a floor, a ceiling arranged opposite the floor, a rear wall arranged opposite the closed door and two side walls placed opposite each other.
  • the pull-out direction is oriented in particular from the rear wall in the direction of the, in particular closed, door. Accordingly, the insertion direction is oriented from the door, especially when it is closed, towards the rear wall.
  • the spray arm is preferably movable with respect to the washing container.
  • the spray arm is attached or mounted on the washware holder.
  • the spray arm preferably comprises a plurality of nozzles or spray nozzles, with the help of which the items to be washed in the item holder are wetted with washing liquor and/or fresh water in order to clean them.
  • the spray arm can also have drive nozzles from which rinsing liquor and/or fresh water emerge laterally in order to set the spray arm in rotation.
  • the spray arm is driven passively.
  • the spray arm can therefore be referred to as a passive spray arm.
  • the spray arm can also be actively driven. “Active” in this case means that the spray arm has a separate drive element, for example in the form of an electric motor and/or a gear.
  • the household dishwasher can have several items to be washed.
  • the household dishwasher has a lower washware receptacle or a lower basket, an upper washware receptacle or an upper basket and a cutlery drawer.
  • the spray arm and the spray arm rotating device are attached to the upper washware holder or the upper basket.
  • the spray arm and the spray arm rotating device can also be attached to any other dish holder.
  • the washware receptacle to which the spray arm and the spray arm rotating device are attached is an upper washware receptacle or an upper basket. Therefore, the term “washing item holder” can also be replaced by the term “upper basket” below.
  • the movement element is in particular rod-shaped.
  • the movement element can be a thrust element or can be referred to as such.
  • the movement element is preferably suitable for carrying out a pushing movement.
  • the movement supply element can also be a tension element or be referred to as such.
  • the movement element is preferably suitable for carrying out a pulling movement.
  • the movement element can also be a combined push and pull element or can be referred to as such. In this case, the movement element is preferably suitable for carrying out both a pulling movement and a pushing movement.
  • the movement element is mounted on the washware holder so that it can be moved linearly in such a way that the movement element can move along the pull-out direction and along the insertion direction.
  • the fact that the movement element is "supported" in or on the washing container means in the present case that the movement element contacts the washing container, in particular its rear wall, when the washware receptacle is moved into the washing container, whereby the movement element is linearly displaced with respect to the washware receptacle in order to interact with the spray arm so that it starts rotating.
  • the movement element moves along the extension direction as soon as the movement element comes into contact with the rear wall.
  • “in or on” the washing container means, in particular, that the movement element can be supported on any component accommodated within the washing container and, on the other hand, that the movement element can also be supported directly or directly on the washing container, for example on the rear wall .
  • the movement element is supported on the rear wall of the washing container when the washware holder is moved in the direction of insertion into the washing container in order to set the spray arm into rotational movement.
  • the movement element and the spray arm form a retrofit component or a retrofit component.
  • the household dishwasher can therefore be retrofitted with the movement element and the spray arm.
  • the movement element and the spray arm can be part of a spray arm arrangement of the household dishwasher. This spray arm arrangement can be retrofitted.
  • the spray arm can, for example, be mounted directly rotatable on the washware holder.
  • a feed pipe for supplying washing liquor and/or fresh water to the spray arm can be mounted on the washware holder.

  • the counter-engagement element slides over the engagement element when the items to be washed are moved out of the washing container in the pull-out direction, thereby deforming the counter-engagement element in a resilient manner. This prevents the spray arm from rotating even when the washware holder is moved out of the washing container.
  • the engagement element has a plurality of plate-shaped engagement wings, between which the counter-engagement element engages in a form-fitting manner in order to set the spray arm into rotational movement when the washware holder is moved in the direction of insertion into the washing container.
  • the number of engagement wings is arbitrary. For example, twelve such engagement wings are provided. However, fewer or more than twelve engagement wings can also be provided. “Plate-shaped” in this context can mean that the engagement wings have a constant or consistent thickness or wall thickness.
  • the engagement wings are arranged evenly distributed around an axis of rotation of the spray arm.
  • the spray arm is mounted on the washware receptacle in particular so that it can rotate about the axis of rotation.
