Definitions

  • the present invention relates to a household dishwasher and a method for operating a household dishwasher.
  • a dishwasher comprises a wash chamber in which the items to be cleaned are placed.
  • a rotating spray arm may be provided within the wash chamber to spray the items with wash water and/or fresh water.
  • This spray arm can be driven either by the pressure of wash water and/or fresh water exiting spray nozzles on the spray arm or by an active drive, particularly an electric motor.
  • an actively driven spray arm cannot be moved manually. Therefore, a problem can arise if the spray arm becomes stuck in a position that obstructs access to other components within the wash chamber.
  • US 9,220,393 B2 This describes a dishwasher with an actively driven lower spray arm.
  • a sensor detects when the spray arm is above it or moves away from it during a rotation. Based on this sensor signal, the rotational movement of the spray arm can be calculated. The system ensures that the spray arm stops in a position where it does not obstruct access to the filter system.
  • Disclosing a dishwasher arrangement includes a motor for driving a spray arm.
  • the position of the spray arm can be determined based on a sensor signal.
  • This sensor signal is output by a sensor located on a drive shaft that powers the spray arm.
  • one object of the present invention is to provide an improved household dishwasher.
  • a household dishwasher comprising a wash tub, a container located outside the wash tub for holding an operating medium (accessible via an opening in the interior of the wash tub when the dishwasher door is open), a spray arm for applying wash water to the items in the wash tub, a drive unit for actively driving the spray arm, and a control device for controlling the drive unit.
  • a sensing device for detecting the angular position of the drive unit is associated with a drive element of the drive unit.
  • the control device is configured to determine the angular position of the spray arm based on the detected angular position of the drive element and to control the drive unit to stop the spray arm within a predetermined angular range outside an angular range defined by an access area of the opening, based on the determined angular position of the spray arm.
  • the predetermined angular range is defined such that, furthermore, a longitudinal direction of the spray arm within the predetermined angular range is parallel to the insertion direction of an item holder in the household dishwasher.
  • This household dishwasher offers the advantage that the position of the actively driven spray arm is always precisely known. This allows the spray arm to be stopped within a clearly defined area when the current wash program is interrupted or completed. This prevents the actively driven spray arm from stopping in a position that obstructs or blocks access to certain components of the dishwasher. Because the position is monitored by a sensing device associated with the drive element, located in a separate or protected area from the wash tub (e.g., outside the tub), the reliability and lifespan of the sensing device are improved. Furthermore, the sensing device can be simpler in design, as it does not require additional protection from the extreme conditions inside the wash tub during a wash cycle. Overall, this makes the operation of the household dishwasher more reliable and easier.
  • the household dishwasher comprises a wash container which is preferably sealed fluid-tight from one side by means of a door that can be pivoted about an axis.
  • the door can be opened to load the wash tub with dishes.
  • other components of the household dishwasher may be accessible inside the wash tub.
  • a filter screen located above a sump or pump housing, or a salt container may be accessible.
  • the container for receiving the operating fluid is located outside the rinsing tank and has an opening accessible from inside the rinsing tank.
  • the container can be filled with the operating fluid via this opening.
  • the operating medium can be, for example, a consumable that is used and consumed during one or more washing cycles.
  • the container is preferably designed to hold a supply of the operating medium, so that the medium is sufficient for several washing cycles.
  • the container can also have additional openings.
  • the container can be connected to a hydraulic system of the household dishwasher and/or has a feeder for introducing or removing the operating medium and/or another substance.
  • the spray arm is, for example, a lower spray arm located in the wash tank and above its base.
  • the spray arm is, in particular, rotatably mounted, with one axis of rotation of the spray arm running essentially perpendicular to the base.
  • "Essentially perpendicular" here means, in particular, that the base may have a slight incline, for example, up to 25°, to allow for the drainage of wash water. It can also be said that the spray arm is rotatably mounted in a horizontal plane.
  • “spraying” the items with cleaning solution means that the items are wetted with cleaning solution by means of the spray arm.
  • Cleaning solution can refer to water containing a cleaning agent or even pure drinking water.
  • the cleaning solution may include soiling removed from the items.
  • actively driven means that the drive unit applies torque to the spray arm. Active driving does not, in particular, refer to the rotation of the spray arm by means of spray nozzles.
  • the drive unit for actively driving the spray arm includes a drive element, in particular an electric motor. However, the drive unit may also be hydraulically actuated.
  • the control device can be implemented in hardware and/or software.
  • the control device can, for example, be a computer or a microprocessor.
  • the control device can be a computer program, a function, a routine, part of program code, or an executable object.
  • the control device for controlling the household dishwasher as a whole is based on one of several Dishwashing programs are set up.
  • the fact that the control device controls the drive device means, in particular, that the control device rotates the spray arm at a certain speed or frequency, accelerates, stops, and/or moves it into a certain position, especially an angular position.
  • the drive unit is preferably coupled to the spray arm purely mechanically, and may include one or more drive elements.
  • the drive unit transmits the torque to drive the spray arm via a drive shaft.
  • one or more gears and belts may be provided.
  • the sensing device is associated with a drive element, such as the drive shaft.
  • the sensing device being associated with the drive element means, in particular, that it is configured to detect the angular position of the drive element by means of a direct measurement.
  • the sensing device includes a Hall sensor, and a magnetic signature is applied to the drive element.
  • the Hall sensor is arranged in close proximity to the drive element in such a way that it detects a change in the magnetic flux due to a rotation of the drive element.
  • the drive element to which the detection device is assigned is preferably designed for power transmission within the drive unit.
  • the drive element can also be coupled to another power-transmitting drive element, for example, by means of a gear.
  • the detection device can be directly coupled to the spray arm.
  • the detection device detects the angular position of the drive element.
  • Angular position is understood here to be the degree of rotation of the drive element relative to a reference or zero position.
  • the detected angular position corresponds, in particular, to the current angular position of the drive element.
  • the angular position is detected at a specific frequency or at specific time intervals. For example, the angular position is detected once, twice, or even N times, where N can be any integer, per revolution of the drive element.
  • the angular position between two detection times can be determined by interpolation.
  • the angular position of the drive element is preferably coupled to the angular position of the spray arm via a fixed and known function.
  • the angular position of the spray arm is proportional to the angular position of the drive element.
  • a gear ratio may be present, whereby, for example, one revolution of the drive element corresponds to a fraction of a revolution or more than a revolution of the spray arm.
  • the angular position of the spray arm corresponds to that of the drive shaft.
  • the control device is configured to determine the angular position of the spray arm as a function of the detected angular position of the drive element.
  • the detected angular position of the drive element corresponds exactly to an angular position of the spray arm. Accordingly, the control device "knows" the angular position of the spray arm once the angular position of the drive element has been detected.
  • the rotational frequency of the drive element is known, from which the rotational frequency of the spray arm can also be derived or determined. Assuming that the rotational frequency is constant during the period between two detection times of the angular position of the drive element, the angular position of the spray arm is thus known at any given time.
  • the control device can actuate the drive unit so that the spray arm is stopped within a predetermined angular range.
  • This predetermined angular range lies, in particular, outside of an angular range defined by the access area of the opening.
  • access area refers specifically to an area that should be clear for easy, i.e., unobstructed, access to the opening.
  • the access area is defined by a volume of 10 cm in every direction from one edge of the opening. If the opening is located at the bottom of the washing tank, the access area preferably includes an area above the opening. This ensures that the opening is easily accessible, particularly without obstruction from the spray arm.
  • the spray arm is stopped within the predetermined angle range when a wash program has finished and/or a running wash program is interrupted, for example, when a user of the household dishwasher opens the door. Furthermore, the spray arm is also stopped within the predetermined angle range, in particular, when it is not currently in use during a wash program, for example, because only another spray arm, such as an upper one, is active and/or because a soaking phase, heating phase, or the like is included in the wash program.
  • the opening can be closed with a lid.
  • the opening can be sealed fluid-tight with the lid.
  • the household dishwasher has a water softening device for adjusting the hardness of the supplied water, wherein the container includes a salt container arranged under a base of the wash tank for holding a supply of regeneration salt.
  • the water softener consumes the regeneration salt over time and therefore needs to be refilled after a certain number of rinse cycles. This is easily done in this case because the spray arm stops outside the reach of the salt container opening.
  • the predetermined angular range is determined in such a way that, furthermore, a longitudinal direction of the spray arm in the predetermined angular range is parallel to an insertion direction of a dishwashing basket of the household dishwasher.
  • the spray arm has a particularly elongated or linear shape.
  • the spray arm comprises two arm sections that extend radially outwards from the axis of rotation of the spray arm.
  • This embodiment is advantageous because, for example, items protruding downwards from the dish holder, particularly cutlery, are virtually prevented from colliding with the spray arm when the dish holder is inserted into the wash container.
  • a collision can only occur if, for example, the item protrudes precisely in the center of the dish holder, and even then, a slight lateral movement of the item resolves the collision.
  • "Parallel” here refers to an angular range that deviates, for example, from -20° to +20° from the exact parallel direction.
  • a gearbox for power transmission is arranged between the drive unit and the spray arm, wherein the control device is designed to determine the angular position of the spray arm as a function of a gear ratio.
  • the gearbox can have different gear ratios.
  • the spray arm comprises a spray arm satellite rotatably mounted on the spray arm, wherein the spray arm satellite is outside the access area of the opening in the predetermined angular range of the spray arm in any arbitrary rotational position of the spray arm satellite.
  • the spray arm satellite is arranged, in particular, on one of the two arm sections of the spray arm and is mounted so as to rotate freely.
  • the spray arm satellite is preferably driven by means of obliquely arranged spray nozzles.
  • the recoil of the ejected spray solution sets the satellite spray arm in motion.
  • the spray arm satellite is connected to the spray arm, for example, by means of a fastening element.
  • the fastening element can be released, for example, to disassemble the spray arm.
  • the spray arm satellite preferably comprises several arms.
  • the spray arm satellite can have three arms, each arranged at an angle of 120° to one another. However, the number of arms is, in principle, arbitrary.
  • a rotation axis of the spray arm and a rotation axis of the spray arm satellite are arranged parallel to each other and spaced apart from each other.
  • the axis of rotation of the actively driven spray arm does not coincide with the axis of rotation of the spray arm satellite.
  • the distance between the two axes of rotation can be several centimeters.
  • the detection device for detecting the angular position of the drive element comprises an optical, magnetic, electrical and/or mechanical sensor device.
  • the sensor device can, for example, include a light-emitting diode, in particular a laser diode, a measuring scale, and a photodiode. Furthermore, a Hall sensor and/or an electrical resistance encoding can be provided to detect the angular position. Mechanical elements, such as a protrusion or the like, can also be used as a sensor device.
  • the detection device for detecting the angular position of the drive element is set up with an accuracy of 10°, preferably 8°, more preferably 5°.
  • the drive unit comprises an electric motor located outside the washing tub.
  • the detection device is set up to detect the angular position of the drive element depending on a sensor signal from a motor control of the electric motor.
  • a method for operating a household dishwasher comprises a wash tub, a container located outside the wash tub for holding an operating medium, which is accessible via an opening in an interior of the wash tub when the dishwasher door is open, a spray arm for applying washing solution to the items in the wash tub, a drive unit for actively driving the spray arm, and a control device for controlling the drive unit.
