Abstract: A household appliance, particularly a floor treatment appliance, has an appliance housing, a fan arranged in the appliance housing, an outlet opening formed in the appliance housing downstream of the fan, a flow channel connecting the outlet opening to the fan in a flow-conducting manner, and a sound absorption device assigned to the flow channel in order to absorb sound generated by the operation of the household appliance. In order to create a sound absorption device that can be installed into the household appliance in a particularly simple manner, the sound absorption device comprises a plurality of sound-absorbing wall elements and a carrier body that accommodates the wall elements in a reversible manner, wherein a flow path is formed within the carrier body between opposing wall elements.

Abstract: A cutting disc configured to chop food products by rotating about an axis. There are cutting elements which are located on a first side of the cutting disc and which can chop food products by rotating the cutting disc in a first direction of rotation and which are arranged one behind the other when viewed in the first direction of rotation. The cutting elements arranged one behind the other are different.

Abstract: A mobile household appliance has an appliance housing, a display that forms part of an outer shell of the appliance housing, a detection device for detecting an operating parameter that characterizes an operating mode of the household appliance, and an evaluation and control unit for determining the operating mode and for depicting at least one piece of information concerning the current operating mode on the display. The evaluation and control unit varies a depicting direction of the displayed information depending on the determined current operating mode of the household appliance. The detection device has a sensor that is designed for detecting a relative orientation of a handle of the household appliance, which can be adjusted relative to the appliance housing, or a contact sensor for detecting mechanical contact of the household appliance with a service station, or an accumulator monitoring device for detecting charging or discharging of the accumulator.

Abstract: A system of a household appliance has an appliance housing, an accumulator having an accumulator housing and an integrated optical display, and a display control for controlling a display of information on the accumulator display. The appliance has a detector for determining appliance states of the appliance, which do not relate to the accumulator, wherein the detector is configured to transmit the detected appliance state to the display control, wherein the display control is configured to control the accumulator display to display the received appliance state. The display control is configured to control the display of a remaining running time, which specifies how long a charging capacity, which is still available in the accumulator, will last, to complete an activity, which is currently performed, wherein the remaining running time relates to a combination of an appliance parameter of the appliance and of the current charging capacity of the accumulator.
