By way of example, the interlocking device 35 may have a magnetic coil, which is configured to move the interlocking element 36, which can be, for example, a bolt, to make it engage in drag with a gear section provided on the rear wall 7 of the washing tank 2. The element of interlocking 36 can also be an electromagnet, which is configured to couple the interlocking device 35 with the rear wall 7 in a fixed manner.
    The lifting device 17 further comprises a spring device 37, which couples the interlocking device 35 with the upper wash article housing 11. The spring device 37 may be, for example, a cylindrical spring. The spring device 37 is disposed between the rear wall 34 of the upper washing article housing 11 and the rear wall 38 of the locking device 35. By way of example, the spring device 37 may be mounted next to the rear walls 34 , 38 in a fixed way.
    Next, the functionality of the lifting device 17 is explained by means of Figures 1 to 7, to which reference is made simultaneously. To move the lower wash item housing 10 from the initial position PA to the final position PE, the lower wash item housing 10 is first completely removed from the


    wash tank 2, so that the housing for wash items 10 below is in the initial position PA. If the housing for wash items 10 below is completely removed from the wash tank 2, it can be determined by the corresponding sensors. Now, the control device 25 is configured to activate the driving device 24 to raise or lower the lower wash article housing 10 by manually moving the upper washing article housing 11 in the washing tank 2, depending on a force of actuation F1, F2 manual acting on the housing for washing items 11 and / or the travel path ∆l.
    A first manual driving force F1, in particular, a pressure force (Figure 4), which acts in the direction of the rear wall, is applied firstly to the housing for upper washing articles 11 introduced in the washing tank 2 7. Here, the interlocking device 35 is still disposed away from the rear wall 7 of the washing tank 2, and the upper washing article housing 11 is not yet locked in the washing tank 2. The interlocking device 35 is not It is nestled. The unlocked state of the locking device 35 is shown by showing the locking element 36 as an empty circle. Applying the driving force F1, the upper wash article housing 11 is introduced to a greater extent in the washing tank 2 until the interlocking device 35 comes into contact with the rear wall 7 (Figure 5). The interlocking device 35 continues without being interlocked.
    The upper housing for washing items 11 being introduced to a greater extent in the washing tank 2, the spring device 37 is compressed and the travel path ∆l is reduced. Here, the driving force F1 acts against the elastic force of the spring device 37. As shown in Figure 6, as soon as it falls below a lower threshold value of the travel path ∆l, the device for interlocking 35 is activated and the interlocking element 36 couples the interlocking device 35 with the rear wall 7 of the washing tank 2. The interlocked state of the interlocking device 35 is shown by showing the interlocking element 36 as a filled circle. Additionally, as soon as the interlocking device 35 is interlocked, the driving device 24 is activated by the control device 25, so that the lower washing article housing 10 is raised from the initial position PA to the final position PE.
    The smaller the travel path ∆l and / or the greater the driving force F1, the greater the speed of movement when the housing is raised for


    wash items 10 lower. As a requirement for the interlocking of the housing for upper wash items 11 and the activation of the driving device 24, the lower laundry housing 10 must be completely removed, which is ensured by the sensors described above. As soon as the driving force F1 ceases to be applied on the upper washing article housing 11, the lower washing article housing 10 will remain in its current position. For this, an interlocking device, for example, a self-locking helical gear associated with the driving device 24, can be provided for locking the housing for lower wash items 10.
    If, as shown in Figure 7, a second manual driving force F2 is applied to the housing for blocked upper wash items 11, in particular, a pulling force, directed in the direction opposite to the rear wall 7 , and an upper threshold value of the travel path ∆l is exceeded, the lower washing article housing 10 is lowered from the final position PE to the initial position PA. As soon as the lower wash item housing 10 has reached the initial position PA, the interlocking device 35 is unlocked or unlocked, so that the upper wash item housing 11 is no longer locked in the wash tank 2 and can be extracted from it. If no driving force F1, F2 is exerted on the housing for upper wash items 11 while it is locked, then the drive device 24 is deactivated and the lower wash housing 10 remains in its current position. For this, the driving device 24 may comprise the self-locking helical gear mentioned above.
    The lifting device 17 further comprises a sensor device 39 for direct detection of the driving force F1, F2. The sensor device 39 may be provided next to the washing tank 2, to the upper washing article housing 11, or to the handle 12 of the upper washing article housing 11. Preferably, the sensor device 39 is in effect connection with the handle 12, so that the driving force F1, F2 is detectable as soon as it is applied to the handle 12. The sensor device 39 can be called the first sensor device 39 and, the sensor device 33, second sensor device 33. The lifting device 17 may comprise both sensor devices 33, 39 or only one of the sensor devices 33, 39.
    With respect to the known approaches to solve the exposed technical problem, the lifting device 17 has the advantage that the user does not have to lean towards the housing for lower washing items 10 to operate the


    lifting device 17, since the lifting device 17 is always handled by means of the upper wash article housing 11, in particular, by the handle 12 of the upper washing article housing 11, regardless of the position of the housing for wash items 10 lower. Likewise, it is not necessary to install 1 additional sensor buttons or fields in the dishwasher 5 to direct the lifting device 17. Since the lifting device 17 for raising or lowering the housing for lower washing items 10 is only activated if the housing for washing items 11 above it is completely in the washing tank 2, the possibility of a collision of the housing for washing items 10 is excluded
    10 lower with the housing for washing items 11 upper. In addition, the transmission of data and / or energy to the washing chamber 4 of the washing tank 2 is also not necessary.
    Although the present invention has been described by means of embodiments, it is modifiable in various ways.
