Abstract: An air humidification device (1) includes a housing (2) having a front side and a rear side, on which housing an air inlet opening (3) and an air outlet opening as well as a water connection (5) for supplying water are provided. A porous ceramic plate is disposed in the housing in the air guide path thereof, which is formed between the air inlet opening and the air outlet opening, in such a way that the air passing through the air humidification device flows through the ceramic plate. The ceramic plate is surrounded by a frame at least on the front side, which frame is detachably and reattachably fixed in the housing. The housing has a detachable and reattachable housing wall part (4), upon removal of which the frame with the ceramic plate is accessible and can be removed from or inserted into the housing, respectively. In this way, an easy cleaning of the ceramic plate is possible.

Abstract: The invention relates to a hydraulic device (15; 55) for an evaporative system (11), comprising at least one pump (22; 62) and a housing (16; 56) with a water inlet (17; 57) and one or more water outlets (19; 59), wherein the at least one pump (22; 62) is mounted on the housing (16; 56) and a water tank (20; 60) is provided by the housing (16; 56), the water tank (20; 60) being arranged between the water inlet (17; 57) and the one or more water outlets (19; 59), wherein the at least one pump is provided for pumping water through the one or more water outlets. The invention furthermore relates to an evaporative system (11) with such a hydraulic device (15; 55).

Abstract: An oven, especially a domestic oven, can comprise a cooking cavity and at least two carrier structures arranged at each side of the cavity respectively for holding an auxiliary element for cooking food, wherein each carrier structure comprises at least one column extending in a vertical direction (V) within the cavity, and at least one holding element for holding the auxiliary element. The holding element is moveable along at least a sliding range of the column or columns in the vertical direction (V) in a sliding movement, so that the holding element is adjustable in its vertical (V) height within the cavity. And, the columns and the corresponding holding elements comprise corresponding guiding surfaces each extending in the vertical direction (V) and are in contact with each other during the sliding movement so that, during the sliding movement, the holding element is guided by the column or columns.
