Abstract: A filter cartridge for filtering water, for use in an air humidifier, having a storage chamber for storing filter material, and having at least one opening for feeding to the storage chamber and/or for releasing from the storage chamber the water to be filtered is proposed. For the purpose of relatively quick filling, the filter cartridge is formed to be arranged in a container, containing water to be filtered, such that the filter cartridge can project at least partially into the water stored in the container, with the at least one opening formed both as a water inlet for feeding water from the container into the storage chamber and as a water outlet for discharging water from the storage chamber into the container. A roller, an air humidifier and a filtering method are also proposed.

Abstract: An apparatus for utilizing water such as, for example, an atomizer or vaporizer, having at least one container for water. Here, two ceramic electrodes that can be used to treat the water are arranged for the purpose of improving the water quality in the container.

Abstract: An air humidifier including a first container and a second container that can be filled with water from the first container, an atomizer and electrodes. The second container is subdivided into a first reservoir and a second reservoir, the two reservoirs being interconnected with the interposition of a filter. Two electrodes are arranged in the first reservoir, and a component of the atomizer is arranged in the second reservoir in order to atomize the water.

Abstract: The invention relates to a aroma cartridge for a device for dispensing aroma substances, the aroma cartridge comprising at least one vessel having at least one cavity for receiving an aroma medium, the cavity having at least one opening, the opening being closed off by a metering device. Furthermore, the invention relates to the device for dispensing aroma substances from a aroma cartridge and to a method for operating the device.

Abstract: A drive for rotating an article such as a roller shaft or plate has a gear which is connected to the rotating article in a rotationally fixed manner. The gear has a number of teeth. A means for driving the gear has a movably mounted lever with a tip that meshes with the gear to have driving contact with the gear and impart driving motion to the gear. The tip forms a tooth and the gear teeth and the tooth of the lever tip are shaped to mesh with a rolling contact between them during the driving motion.

Abstract: A fragrance evaporator allows doses of fragrance to be released into the atmosphere in a controllable manner and only when required. The fragrance evaporator has a solid surface that may be wetted as required with liquid fragrance from a fragrance reservoir. An evaporation space that surrounds the solid surface and that is in communication with the atmosphere is thus created above the surface.

Abstract: An appliance for purifying, humidifying or dehumidifying, cooling or heating gases, especially room air, and in it purification is carried out by means of a plate stack rotating in a liquid. To regulate or vary the air humidity, the incoming air is conveyed through an evaporator and the purified outgoing air is conveyed through a condenser of a refrigerant circuit. The effectiveness of the condenser is influenced by an additional condenser.
