Abstract: The invention relates to a device (1), in particular to a cleaning robot, for processing a surface (2), wherein the device (1) has an optical measuring device (3) for determining the type of surface (2).

Abstract: A self-propelled surface treating device, in particular a cleaning robot, with a device housing and a collision detection device for detecting a collision between the surface treating device and an obstacle, wherein the collision detection device has at least one touch-sensitive contact sensor. In order to protect the surface treating device against impacts in the vertical direction, it is proposed that the touch-sensitive contact sensor be a vertical contact sensor, which is arranged on the device housing in such a way that its detection area is vertically aligned during a movement with the surface treating device conventionally oriented, so that the vertical contact sensor is configured to detect a force acting vertically on the surface treating device.

Abstract: A preparation vessel with a vessel floor, a heating device and a foot part that can be externally connected with the vessel floor, wherein the preparation vessel can be connected by way of the foot part with a base unit of an electric motor-operated food processor. In order to be able to use the preparation vessel even at high temperatures, it is proposed that a heat protection element with a temperature resistance of at least 160° C., in particular of at least 200° C., be arranged between the vessel floor and foot part, in particular between the heating device and foot part.

Abstract: A method for processing, in particular cleaning, a floor of a room using an automatically movable processing device. A map of the room is generated and displayed to a user of the processing device, and the user can select at least one room sub-region in which the processing device is to process or refrain from processing the floor in the generated map. The aim of the invention is to provide a method for processing a floor, wherein the generated map of the room is easier to read for the user. This is achieved in that the map of the room is generated from three-dimensional coordinates of a world coordinate system, each point of a plurality of points of the room and/or of an obstacle arranged in the room being assigned to a three-dimensional coordinate within the world coordinates system.

Abstract: The invention relates to a method for operating an electric motor-driven kitchen appliance for preparing a material to be prepared based on a recipe, wherein the material to be prepared is prepared in a vessel of the kitchen appliance via one or more consecutive preparation steps, in particular stirring and/or heating and/or chopping, wherein a current status parameter of the material to be prepared and/or a current operating parameter of the kitchen appliance is determined.

Abstract: A system comprising a vacuum cleaner and a base station, wherein the vacuum cleaner has a suction opening for sucking up dirt and/or dust from a floor by a suction air flow, a fan for producing the suction air flow, a dust chamber for holding dirt and/or dust, and an air outlet opening such that air sucked in together with the dirt and/or dust can be discharged again. The base station can be connected to the vacuum cleaner in such a way that the dust chamber can be emptied into the base station by means of an air flow. The air flow used to empty the dust chamber can be produced and blown into the dust chamber by the fan for producing the suction air flow. The base station has a return channel, through which the air flow exiting the dust chamber can be guided back into the vacuum cleaner.

Abstract: A mixing vessel for an electric motor-operated food processor, with a vessel floor, an agitator extending through the vessel floor into the mixing vessel, and a foot part that can be externally connected with the vessel floor, which is designed for fixing the agitator to the vessel floor. In order to prevent a user from filling the mixing vessel without the agitator properly assembled in the food processor, it is proposed that the vessel floor or foot part have a blocking element that can be exposed to the spring force of a spring element, and can be shifted against the spring force by means of a corresponding contact element of the foot part or vessel floor from a blocking position that prevents a fixation of the agitator into a release position that enables a fixation.

Abstract: The invention relates to an electrically operatable kitchen device for preparing food by means of one or more effective devices. An effective device can be activated and/or adjusted by a rotary knob and/or push button, and the kitchen device can be deactivated in terms of one or simultaneously more or all of the activated effective devices. The aim of the invention is to provide an electrically operatable kitchen device with an advantageously deactivatable effective device. According to the invention, this is achieved in that the deactivation of the effective device can be triggered depending on the speed at which the rotary knob is moved in the direction of the rotational axis of the rotary knob, in the rotational direction, or in the opposite rotational direction.

Abstract: A mixing vessel for a food processor operated by an electric motor, which mixing vessel has a mixing mechanism which can be connected to a rotary drive of the food processor by means of a coupling driver, wherein the mixing vessel has a cleaning device for cleaning an inner wall of the mixing vessel, in particular a floor of the vessel. The cleaning device is arranged on the mixing vessel, in particular on a vessel wall and/or the mixing mechanism, and has at least one cleaning element which is designed such that, upon actuation of the cleaning device, it sweeps over the inner wall and/or over sub-regions of the mixing mechanism and, by interacting mechanically with any deposits which may be located on the inner wall and/or the mixing mechanism, helps to remove the same.

Abstract: An electric kitchen appliance has a pot for receiving food to be processed using the electric kitchen appliance. An ultrasound transmitter and an ultrasound receiver are provided in order to determine the fill level of the food in the pot. The ultrasound transmitter and the ultrasound receiver are attached to the upper edge of the pot such that an ultrasound signal can be transmitted onto the surface of the food by the ultrasound transmitter, and an ultrasound signal reflected by the surface of the food can be received by the ultrasound receiver. In this manner, an electric kitchen appliance is provided which allows the fill state of the food in the pot to be determined in a simple and reliable manner.

Abstract: A food processor, in particular a mixing device, comprising a housing for accommodating a receptacle and a cover that closes the receptacle, and a locking mechanism for interlocking the receptacle with the cover; the locking mechanism includes a locking element, especially a locking roller, which can be moved relative to the receptacle and/or the cover from an unlocking position into a locking position and vice versa. In order to further develop food processors of the type, the locking element, apart from or in addition to interlocking the receptacle with the cover, is designed to have a subsidiary effect on the receptacle and/or the cover or to subsidiarily interact with the receptacle and/or the cover.
