HOUSEHOLD APPLIANCE WITH A SOUND ATTENUATOR

A household appliance has a device housing, a blower arranged in the device housing, an outlet opening formed in a direction of flow behind the blower in the device housing, a flow channel that connects the outlet opening with the blower in terms of flow, and a sound attenuator allocated to the flow channel for attenuating sound arising from the operation of the household appliance. The sound attenuator has sound-absorbing wall elements that have a wall surface that is curved in relation to a direction of a longitudinal extension of the flow channel, a support body for receiving the sound-absorbing wall elements, and a sound-reducing wall with a wall plane oriented parallel to the flow path. The sound attenuator is modular in design, formed of the support body, wall elements and sound-reducing wall, and is installed as a whole into the device housing between the blower and outlet opening.
