Definitions
- the present invention relates to a domestic dishwasher.
- a domestic dishwasher has a washing container and at least one washware receptacle that can be moved into and out of the washing container.
- a household dishwasher can have a plurality of washware receptacles arranged one above the other, such as a lower basket, an upper basket or a cutlery drawer. Since the lower basket is arranged near a bottom of the washware container, it is necessary for loading or unloading the lower basket that the user kneels or bends down towards the lower basket.
- a lifting mechanism can be provided. There are passive lifting mechanisms, which work with the aid of a spring element, and active lifting mechanisms, which have a drive element, for example in the form of an electric motor.
- the document DE 102012 107 993 A1 and the document DE 202009004771 U1 each disclose passive front lifting mechanisms which work with the aid of a spring element.
- the document DE 102015201 806 A1, the document EP 1 066 789 A1, the document WO 2005/104924 A1, the document US 6,247,771 B1, the document US 2006/0066189 A1, the document US 2007/0035220 A1 and the document US 2010 / 0045152 A1 each show lifting mechanisms that work with the help of an electric motor as a drive element.
- a household dishwasher with a washware receptacle for receiving washware and with a lifting device for lifting the washware receptacle from an initial position to an end position and for lowering the washware receptacle from the end position to the initial position.
- the lifting device comprises a spring element for supporting the raising and lowering of the washware receptacle with the aid of a support force and a spring preload adjustment unit which, with the aid of understanding a spring preload of the spring element, adapts the support force to a load condition of the washware receptacle.
- the spring preload of the spring element can be changed with the aid of the spring preload adjustment unit, it is possible to always adapt the support force so that a user can achieve a comfortable actuation force for lifting and lowering the washware receptacle. This increases the ease of use.
- the household dishwasher preferably comprises a washing container in which the washware receptacle can be received.
- the household dishwasher has several washware receptacles.
- three washware receptacles can be arranged one above the other in the washing compartment, with a lower washware receptacle or a lower basket, an upper washware receptacle or an upper basket and a cutlery drawer being provided.
- the lower washware receptacle can be moved from the starting position into the end position and vice versa with the aid of the lifting device.
- the lower washware receptacle is preferably arranged approximately at the level of the upper washware receptacle. This enables simple loading and unloading of the lower washware receptacle.
- the spring element "supports" the raising and lowering is to be understood in the present case in particular that the lifting is not carried out solely by the supporting force of the spring element, but rather that the user applies an actuating force to the washware receptacle in order to move it from the starting position to to spend the final position.
- the spring preload is changed so that the user does not have to work excessively against the supporting force in order to move the washware receptacle from the end position to the start position.
- the actuating force is therefore particularly preferably independent of the load condition of the washware receptacle.
- the actuation force is constant or constant.
- Adjusting the spring preload is to be understood in particular as meaning that the spring element is either stretched or compressed.
- the greater the spring preload the greater the support force.
- the fact that the support force "adapts" to the load condition of the washware receptacle is to be understood in the present case as meaning that the support force increases or becomes greater as the load on the washware receptacle increases. Conversely, the support force decreases as the load decreases.
- the household dishwasher further comprises a sensor device for detecting the load status of the washware receptacle.
- the sensor device preferably includes the loading state indirectly. That is to say, the loading state can be detected, for example, by detecting the weight of the items to be washed that is held in the item to be washed, which acts on the spring element. Alternatively, however, the load status of the washware receptacle can also be detected in a different way, for example optically.
- the sensor device has a strain gauge.
- the sensor device can be part of the spring element.
- the spring element has a cylindrical spring section on which hook-shaped suspension sections are provided at the end.
- the sensor device can be arranged in the form of one or more strain gauges between one of the suspension sections and the spring section. In particular, the strain gauge can be glued onto the spring element.
- the sensor device has a torque sensor.
- the torque sensor is preferably provided on a coupling disc to which the spring preload is applied with the aid of the spring element.
- the coupling disc can, for example, be firmly connected to a swivel arm of the lifting device.
- the spring element applies a torque to it Swivel arm on, with the help of the torque sensor the acting torque can be detected.
- the spring preload adjustment unit has an actuating element, in particular a stepping motor, for adjusting the spring preload of the spring element.
- the stepping motor can be a linear motor, for example.
- the stepper motor can, however, also be a rotary motor.
- the spring element can, for example, be coupled directly to the adjusting element. The adjusting element can then expand or compress the spring element to increase and decrease the preload.
- the spring preload adjusting unit has an adjusting disk which is coupled to the adjusting element and the spring element, the spring element being coupled to the adjusting disk off-center.
- the adjusting element can set the adjusting disk in rotation about an axis of rotation.
- "Eccentric" means in the present case at a distance from the axis of rotation of the adjusting disk.
- the adjusting disk can have a cam or a bolt into which the spring element is suspended with one of its suspension sections.
- the spring preload adjustment unit can, for example, be attached to the washing compartment of the domestic dishwasher.
- the spring element is a tension spring
- the spring preload adjustment unit stretching the spring element to increase the spring preload
- the spring preload adjustment unit can move the spring element continuously from an initial state in which the spring preload is minimal via any number of intermediate states to an end state in which the spring preload is at a maximum.
- the spring preload adjustment unit has an engagement element which is coupled to the actuating element with the aid of a threaded spindle.
- the threaded spindle can be part of the adjusting element.
- the adjusting element can set the threaded spindle in rotation.
- the engagement element can be a nut placed on the threaded spindle, which nut moves linearly along the threaded spindle when the threaded spindle rotates.
- the spring element is arranged between the engagement element and a lever arm of a coupling disc.
- the coupling disc can be connected, for example, to one of the pivot arms of the lifting device.
- the sensor device with the torque sensor can be provided on the coupling disk.
- the spring element is a compression spring
- the spring preload adjustment unit compressing the spring element to increase the spring preload
- the spring element is compressed in that the engagement element moves towards the lever arm of the coupling disc. To relax the spring element, the engagement element moves away from the lever arm again.

- the adjustment disk 27 is rotated as a function of the load condition of the washware receptacle 12 detected with the aid of the sensor device 24. That is, the higher the load condition and thus the weight of the washware receptacle 12, the greater the spring preload FV (arrow) and the greater is also the support force FU (arrow) when lifting the washware receptacle 12 from the starting position AP into the end position EP. That is, regardless of the load condition of the washware receptacle 12, a user must always apply approximately the same actuating force FB (arrow) in order to raise the washware receptacle 12 from the starting position AP to the end position EP.
- the drive mechanism 19A therefore does not lift the washware receptacle 12 automatically, but rather supports the user in lifting it with the assistance force FU.
- the support force FU (arrow) is, as mentioned above, dependent on the load condition of the washware receptacle 12.
- the actuation force FB (arrow), however, which the user has to apply himself, is preferably independent of the load condition.
- the actuating force FB (arrow) is preferably constant or constant.
- the drive mechanism 19A also supports the lowering of the washware receptacle 12 from the end position EP into the starting position AP.
- the support force FU depends on the load status of the washware receptacle 12. That is, if the washware receptacle 12 is empty or lightly loaded, the spring preload FV (arrow) is reduced so that the user does not push the washware receptacle 12 against the spring element 20 must press down. At In contrast, when the load is high, the spring preload FV (arrow) is increased so that the washware receptacle 12 does not move in an uncontrolled manner from the end position EP to the starting position AP.
- the actuation force FB which the user has to apply is thus independent of the load condition of the washware receptacle 12.
- the actuation force FB (arrow) is preferably constant or constant.
- the drive mechanism 19A is thus semi-passive.
- the lifting device 16 can therefore be referred to as a semi-passive lifting device 16.
- the drive mechanism 19A it is possible to adapt the assisting force FU (arrow) to the load on the washware receptacle 12.
- the actuation force FB (arrow) can be kept in a range that is comfortable for the user. This improves the ease of use.
- FIG. 7 schematically shows a diagram associated with the drive mechanism 19A, in which the force in Newtons is plotted against the lifting height in millimeters.
- the fully loaded washware receptacle 12 is marked with a solid line.
- the empty washware receptacle 12 is marked with a dashed line, and the required actuating force FB (arrow) is plotted with a dash-dotted line, which must be applied in order to raise the washware receptacle 12 from the starting position AP to the end position EP.
- Arrows with the reference numeral 32 stand for a relaxation of the spring element 20
- arrows with the reference numeral 33 stand for a tensioning of the spring element 20.
- the spring element 20 is tensioned or relaxed to a to achieve comfortable actuation force FB (arrow).
- the drive mechanism 19B comprises a spring element 34 which is designed as a compression spring.
- the drive mechanism 19B further comprises a spring preload adjustment unit 35 for adjusting a spring preload FV (arrow) of the spring element 34.
- the spring preload adjustment unit 35 has a Adjusting element 36, for example a stepper motor.

- the coupling disk 40 is assigned a sensor device 42 which has a torque sensor 43.
- a braking element 44 can also be assigned to the drive mechanism 19B.
- the braking element 44 can, for example, interact positively with the coupling disk 40 and brake it.
- the braking element 44 can, for example, have a plunger 45 which is actuated with the aid of an electromagnet and which interacts with the coupling disk 40.
- the spring element 34 can be brought from an initial state AZ, in which the spring element 34 is minimally pretensioned, continuously through any number of intermediate states ZZ to an end state EZ, in which the spring element 34 is maximally pretensioned.
- the spring preload FV (arrow) is therefore greater in the final state EZ than in the initial state AZ.
