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 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 includes a scale-collecting container that is removable through the evacuation opening.

First claim

The invention claimed is:

1. An electrical household appliance comprising a base for producing steam having a steam generator comprising a boiling chamber and a liquid reservoir to supply 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 at which the liquid level in the appliance prevents air from entering the reservoir, the boiling chamber comprising a steam outlet through which steam can escape toward a work tool and a communication opening connected to a pipe having an evacuation opening closed with a removable stopper, wherein the pipe includes a scale-collecting container that is removable through the evacuation opening, and wherein the steam outlet is at an upper extremity of the boiling chamber.

2. The electrical household appliance according to claim 1 , wherein the work tool is a smoothing brush.

3. The electrical household appliance according to claim 1 , wherein the scale-collecting container is integral with the removable stopper.

4. The electrical household appliance according to claim 1 , wherein the pipe is supplied with liquid coming from the reservoir through a supply duct that leads to the pipe at the level of an inlet opening.

5. The electrical household appliance according to claim 4 , wherein the inlet opening is arranged over a particle-retention cavity provided in a lower part of the pipe, said scale-collecting container being removably arranged in the particle-retention cavity.

6. The electrical household appliance according to claim 5 , wherein the particle-retention cavity has a longitudinal extremity defined by a transverse wall projecting into the bottom of the pipe.

7. The electrical household appliance according to claim 4 , wherein the scale-collecting container includes a window, arranged opposite the inlet opening, through which the flow of liquid from the reservoir flows and wherein said window has a filtration device.

8. The electrical household appliance according to claim 7 , wherein the filtration device consists of a filtration grate with calibrated openings.

9. The electrical household appliance according to claim 7 , wherein the container includes two gaskets arranged on both sides of the window.

10. The electrical household appliance according to claim 1 , wherein the pipe comprises a first segment fluidically connected to the communication opening and a second segment which is axially offset downward relative to the first segment, the second segment containing the particle-retention cavity.

11. An electrical household appliance comprising a base for producing steam having a steam generator comprising a boiling chamber and a liquid reservoir to supply 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 at which the liquid level in the appliance prevents air from entering the reservoir, the boiling chamber comprising a steam outlet through which steam can escape toward a work tool and a communication opening connected to a pipe having an evacuation opening closed with a removable stopper,
wherein the pipe includes a scale-collecting container that is removable through the evacuation opening, and
wherein the pipe is supplied with liquid coming from the reservoir through a supply duct that leads to the pipe at the level of an inlet opening.

12. The electrical household appliance according to claim 11 , wherein the work tool is a smoothing brush.

13. The electrical household appliance according to claim 11 , wherein the scale-collecting container is integral with the removable stopper.

14. The electrical household appliance according to claim 11 , wherein the pipe comprises a first segment fluidically connected to the communication opening and a second segment which is axially offset downward relative to the first segment, the second segment containing the particle-retention cavity.
