摘要:
The invention relates to a dishwasher machine (1) comprising spray arms (9 to 11), a recirculation pump (5) which is driven by an electric motor (33), and a water point provided on the pump pressure side and used to produce a flow from an inlet (4) to at least one outlet (12 to 14) selected from several and associated with the spray arms (9 to 11). The water point comprises at least one blocking element (20) and a drive element for moving the at least one blocking element (20) which is driven together with the electric motor (33) of the recirculation pump (5). A simple water point drive is achieved in such a dishwasher (1) by mounting a transmission between the drive element and the blocking element (20), said transmission converting a continuous movement of the drive element into a discontinuous movement of the blocking element (20).

The invention relates to a method for evaluating a particle signal (P) by means of an evaluation unit (101) associated with a control device (102), wherein a) the particle signal (P) is generated by means of a sensor (205) within a flow element (202), and is at least dependent on the number of particles in a two-phase flow generated when cleaning a surface (7) by means of a suction device connected to the flow element (202), b) the evaluation unit (101) determines a control signal (103) from the particle signal (P) for further controlling an actuator influenced by the control device (102). In order to reliably consider further influence factors for the presence of dust, besides the quantity of dust, the invention proposes that the evaluation unit (101) considers, in addition to the particle signal, the velocity (G) with which the flow element (202) is moved over the surface (7) when determining the control signal (103).

The invention relates to a method for treating dust (17) and to devices for carrying out this method. In order to improve disposal with regard to hygiene points of view, the invention provides that the dust (17) is separated in a vacuum cleaner (1) into at least two fractions, which differ in the size and/or mass of the dust particles, and that a dust binding agent (43, 52, 60, 84, 122, 134, 170) is added to a fraction.

The invention relates to a dishwasher (1) having a rinsing container (2) that can be closed by a pivoting door (4), wherein to provide locking a locking device disposed on the door (4) engages into a clamp (5) disposed on the rinsing container (2), and wherein to open the door in gaps the clamp (5) is disposed on an adjustable connecting rod (6) that is adjustable in the opening direction by means of a drive. In order to also ensure the automatic retracting of the clamp when the electric gear motor is replaced with a more cost-effective drive, the invention provides means for returning the clamp (5) at least approximately to the initial position thereof opposite to the opening direction as a result of the further opening movement of the door (4).

The invention relates to a suction nozzle for a vacuum cleaner, that can be connected to a suction pipe and/or a suction tube of the vacuum cleaner. Said suction nozzle (2) comprises a nozzle part that can be connected to the suction pipe or the suction tube of the vacuum cleaner by means of a tubular connection part (2.2). A dust sensor (11) is arranged in the flow path of the vacuum cleaner, the signals thereof being evaluated by a battery-operated electronic control device that can be activated by a low-pressure switch. During operation, said control device controls a display device (9,16) displaying the dust flow. The control device, the low-pressure switch, the display elements (9,16) displaying the dust flow, and a battery compartment (8) for receiving the batteries are arranged in a housing (7) formed on the upper side of the tubular connection part (2.2). The dust sensor is arranged beneath the housing (7), inside the upper region of the connection part (2.2), in the dust air stream. Said arrangement can be used to create an easily visible ergonomically favourable dust flow display. A mounting position that is advantageous in terms of flow is also provided for the dust sensor. Fine dust particles can still not be reliably detected with the piezoelectric sensor, enabling the degree of purity to be monitored in an actively functional manner.
