The fall sensors are interconnected in an evaluation circuit of the detection means so that the detection signals of the totality of inner fall sensors can be evaluated independently of the detection signals of the totality of outer fall sensors.

Abstract: A household appliance has a device housing, a blower arranged in the device housing, an outlet opening formed in the flow direction behind the blower in the device housing, and a flow channel. Soundwaves are generated by the blower, and produce resonances characterized by standing waves, which form between opposing inner walls of the flow channel. A sound reducing wall is positioned in the flow channel, the wall plane of which is oriented parallel to a primary flow direction of the air flow guided in the flow channel. The sound reducing wall is positioned in the flow channel so that a maximum for a fast amplitude of a sound particle velocity of the air flow guided in the flow channel lies in the wall plane of the sound reducing wall. The soundwaves form while interspersing the sound reducing wall between the opposing inner walls of the flow channel.
