A Cooking oven (100) comprisinga) at least one cooking cavity (102) andb) at least one steam generation system (40) for introducing steam into the cooking cavity (102) during a steam operating mode, in particular steam cooking mode or steam cleaning mode,c) wherein the steam generation system (40) comprisesc1) at least one steam generator (42),c2) at least one fluid supply (44), the fluid preferably being water with impurities, in particular calcium, and optionally additives andc3) at least one valve (2),d) wherein the valve (2) is interconnected between the fluid supply (44) and the steam generator (42) in order to control the flow of fluid from the fluid supply (44) to the steam generator (42) during the steam operating mode,e) wherein the valve (2) comprises at least one inlet (12) for the fluid being in fluid connection with the fluid supply (44)f) wherein the valve is in fluid connection with the steam generator (42) by means of at least one connecting line (50),g) wherein the valve (2) is provided with at least one closing device (19) for closing and opening the inlet (12) of the valve at least partially during the steam operating mode in order to keep the fluid level within the valve at an operating level within an operating level range during the steam operating mode,h) the cooking oven further comprising one or more of the following features:h1) the valve (2) and the steam generator (42) and the connecting line (50) are arranged in such a way that the level of the fluid within the steam generator (42) and within the valve (2) is kept the same during the steam operating mode and/or wherein the valve (2) and the steam generator (42) and the connecting line (50) are arranged according to the principle of communicating vessels,h2) the operating level (N) or the operating level range during the steam operating mode is, in the direction of gravity, higher than or at the same level as the inlet (12) of the valve (2).

The invention relates to an air purifier (1). The air purifier comprises a housing (2) and an air inlet. A fan is provided inside the housing drawing air from the air inlet towards an air outlet. Further, a filter is provided inside the housing in an air path from the air inlet to the air outlet for filtering the air drawn from the air inlet such that air at the air outlet is filtered air. The air purifier comprises a hood (3) at the air outlet. The hood is configured to be positioned in at least a first position and a second position, where in the first position the hood is in a retracted position configured to let the filtered air exit the outlet without interfering with the direction of air exiting via the air outlet, and where in the second position the hood is in an expanded position configured to direct at least a fraction or all of the filtered outlet air in a predetermined direction. Hereby the air purifier can be made to operate in at least two different modes of operation. Advantageously, in the first mode a diffuse are stream of filtered air is provided and in the second mode a focused air stream of filtered air is provided.

The present invention is related to an extraction device (14) for removing air from an area above a cooking hob (12). The extraction device (14) comprises a suction arm (26), a fan and an outlet opening (34). The suction arm (26) includes a suction head (28), which comprises a suction opening (32), and a suction base (30), which comprises an air duct for conducting the air. The air duct is arranged downstream of the suction opening (32). The fan is configured to suck in the air from the area above the cooking hob (12) through the suction opening (32) and the air duct. The outlet opening (34) is configured to exhaust air. According to the invention, the suction arm (26) is centrally arranged or arrangeable in relation to the cooking hob (12) or is arranged or arrangeable midway between the lateral edges of the cooking hob (12). Further, the position of the suction head (28) and/or of the suction opening (32) is changeable from a position within the boundary lines and at least approximately at the height level of a cooktop (18) of the cooking hob (12) to an elevated position above the height level of the cooktop (18).
