Abstract
An electrical household appliance includes a base for producing steam having a steam generator including a boiling chamber and a liquid reservoir supplying the boiling chamber by gravity, the liquid flowing by gravity from the reservoir toward the boiling chamber until the liquid level in the boiling chamber reaches an equilibrium level, called the reference level, at which the liquid level in the appliance prevents air from entering the reservoir, the boiling chamber including a steam outlet through which steam can escape toward a work tool, such as a smoothing brush, and a communication opening connected to a pipe having an evacuation opening closed with a removable stopper, wherein the pipe is supplied with liquid from the reservoir via a supply duct that leads to the pipe at the level of an inlet opening provided above a particle-retention cavity arranged in the lower part of the pipe.
