A method for operating a domestic appliance to reduce consumption of one or more operating resources includes receiving data about a temporal cost profile of the operating resources, having a first time interval with low costs and a second time interval with high costs, comparing a operating time period with the first time interval and determining a point in time for starting operation as a function of a result of the comparison, when the operating time period is longer than the first time interval, determining a temporal program segment with a higher consumption than other program segments based on a temporal consumption profile that describes consumption as a function of time during operation, and determining the point in time for starting the operation such that the program segment with the higher consumption falls within the first time interval.

A method is provided for operating a dishwasher (1) in the form of a batch dishwasher, which has a treatment chamber (2) for accommodating washware to be cleaned. Provision is made, during an adsorption phase, for air to be conducted out of the treatment chamber (2) through a sorption unit (41), which contains a reversibly dehydratable dry material, in such a way that the dry material absorbs moisture from the air stream, wherein the air is then returned to the treatment chamber (2). Provision is further made, during a desorption phase, for the dry material of the sorption unit (41) to be heated in such a way that moisture is desorbed from the dry material as steam. During the desorption phase, the sorption unit (41) is subjected to forced ventilation only to such an extent that recondensation of desorbed steam in the sorption unit (41) itself is effectively prevented.

Disclosed is a cleaning device for cleaning items to be cleaned. The cleaning device has at least one cleaning chamber and at least one covering device at least partially surrounding the cleaning chamber. The covering device can be moved in an opening movement direction from a closed position into an open position or in a closing movement direction from an open position into a closed position by means of at least one electromechanical drive via at least one transmission. The cleaning device furthermore has a sensor, which is designed to detect an action of a manual force on the covering device in the opening movement direction or in the closing movement direction. The cleaning device is furthermore designed to control the electromechanical drive in accordance with the detection of the action of the manual force.

A warewash machine includes a housing defining a chamber for receiving wares, the chamber having at least one spray zone, a wash spray system for spraying wash liquid onto wares and a rinse spray system for spraying rinse liquid onto wares. At least one radar transceiver is located for detecting wares feeding into the chamber and/or for detecting wares within the chamber. A controller is associated with the radar transceiver and configured to identify one or more of ware location, ware movement, ware size, ware shape and/or ware material based upon outputs from the at least one radar transceiver. The controller is further configured to control at least one operating parameter of the machine based at least in part upon identified ware location, identified ware movement, identified ware size, identified ware shape and/or identified ware material.

A batch-type warewash machine includes a chamber for receiving wares to be cleaned, the chamber having a chamber access opening and a single spray zone, with at least one spray system for spraying liquid onto wares in the single spray zone. A door is movable between a closed position covering the chamber access opening and an open position away from the chamber access opening to allow wares to be moved in and out of the chamber. A curtain structure is mounted on the machine, the curtain structure located behind the door when the door is in the closed position. The curtain structure remains in position and at least partially covers the chamber access opening when the door is in the open position so as to retain hot moist air within the chamber when the door is moved to the open position upon completion of a ware cleaning cycle.

The present disclosure discloses a sequential dishwasher, and relates to the technical field of sequential dishwashers and automatic cleaning methods. The sequential dishwasher includes a casing to the bottom of which a drainage pipe is connected, a dish cleaning mechanism, arranged in the casing; a rotary drive mechanism, arranged below the dish cleaning mechanism; a liquid supply mechanism, arranged in the casing and used for providing a detergent or tap water for cleaning of two sides of a dish in a spraying manner; and a control system, configured to control and connect the dish cleaning mechanism, the rotary drive mechanism, and the liquid supply mechanism for a clamping drive, a rotary drive, and a liquid supply cleaning drive during dish cleaning. The present disclosure further provides an automatic cleaning method for dishes. The present disclosure may effectively save detergent consumption and water consumption of cleaning while realizing rapid cleaning of the single dish, and when facing cleaning of a small number of dishes, may complete the automatic cleaning of the dishes more efficiently with more energy saved.

The invention in particular is directed to a household appliance, such as a washing machine or dishwasher, comprising a heat pump arrangement (3) with a heat pump (4, 5, 6) adapted to transfer heat to an operating medium (2) of the appliance (1, 3), with a closed storage tank (9) adapted to receive a phase change substance (10) and being heat exchangeably coupled with a process side (5) of the heat pump (4, 5, 6), with at least one sensor (11) adapted and arranged to detect an actual phase state of the phase change substance (10), and with a recovery unit (12) adapted and operable to actively recover the phase change substance (10) in dependence of a signal of the sensor (11).

A washing system for determining an operating state of a dishwasher comprises a dishwasher, in particular wherein the dishwasher comprises a dishwasher interface, a dispenser unit, in particular wherein the dispenser unit comprises a dispenser interface, wherein the dispenser unit is connected to the dishwasher for dosing a detergent to the dishwasher, a logic unit, in particular wherein the logic unit is connectable to the dishwasher interface and the dispenser interface, and a current sensor for measuring an electrical current consumed by the dishwasher, wherein the current sensor is connected to the logic unit. By replacing costly water meters by a current sensor, the cost efficiency of the washing system may be increased. In addition, the assembling and maintenance effort of the washing system may be reduced.

A method of opening a door of a household appliance having a cabinet with an open face providing access to a treating chamber where an article is received for treatment according to a useful cycle of operation is provided. The method includes: sensing a presence of at least a portion of a person, visually indicating and automatically opening the door in response to the sensed presence.

A method of opening a door of a household appliance having a cabinet with an open face providing access to a treating chamber where an article is received for treatment according to a useful cycle of operation is provided. The method includes: sensing a presence of at least a portion of a person within a predetermined range of the door and out of contact with the door; and automatically opening the door in response to the sensed presence.
