Abstract

The present application relates to steam iron (10) comprising a soleplate (12), a discharge element (14), a retaining member (16) and a collection compartment (17). The soleplate (12) comprises a steam chamber (13) for generating steam. The steam chamber (13) comprising an opening (13A) arranged at a rear end (R) of the soleplate (12). The discharge element (14) extends from the opening (13A). The collection compartment (17) is formed in the discharge element (14) for collecting calcified deposits (S) formed in the steam chamber (13). The retaining member (16) is arranged in the discharge element (14). T retaining member (16) extends over a front end portion (P1) of the collection compartment (17) to retain the calcified deposits (S) in the collection comportment (17). This invention prevents the calcified deposits from escaping from the collection compartment when the steam iron is tilted.

First claim

The invention claimed is:

1. A steam iron comprising:
a soleplate comprising a steam chamber for generating steam, the steam chamber comprising an opening arranged at a rear end of the soleplate;
a discharge element extending from the opening;
a collection compartment formed in the discharge element for collecting calcified deposits formed in the steam chamber,
a retaining member arranged in the discharge element, wherein the retaining member extends over a front end portion of the collection compartment to retain the calcified deposits in the collection compartment;

wherein the discharge element comprises an aperture for allowing removal of calcified deposits from the collection compartment and a closure for sealing the aperture.

2. A steam iron according to claim 1 , wherein the discharge element comprises a duct extending from the opening and a scale collector having walls defining the collection compartment, the scale collector being removably attachable to the duct.

3. A steam iron according to claim 2 , wherein:
the duct comprises the retaining member; or
the scale collector comprises the retaining member.

4. A steam iron according to claim 2 , wherein the walls of the scale collector include a bottom wall, the retaining member being arranged to overlap the bottom wall when the scale collector is attached to the duct.

5. A steam iron according to claim 2 , wherein the scale collector further comprises at least one aperture to drain water in the scale collector towards the opening.

6. A steam iron according to claim 2 , further comprising a locking member for locking the scale collector to the duct.

7. A steam iron according to claim 2 , wherein the discharge element comprises a cavity, and wherein the scale collector is removably insertable into the cavity.

8. A steam iron according to claim 7 , wherein the cavity and the scale collector are arranged to cooperate such that the scale collector is insertable into the cavity in a direction chosen among the set defined by:
a downward direction compared to a plan formed by the soleplate;
an upward direction compared to a plan formed by the soleplate; and,
a lateral direction compared to a longitudinal axis of the soleplate,
a longitudinal direction compared to a longitudinal axis of the soleplate.

9. A steam iron comprising:
a soleplate comprising a steam chamber for generating steam, the steam chamber comprising an opening arranged at a rear end of the soleplate;
a discharge element extending from the opening;
a collection compartment formed in the discharge element for collecting calcified deposits formed in the steam chamber,
a retaining member arranged in the discharge element, wherein the retaining member extends over a front end portion of the collection compartment to retain the calcified deposits in the collection compartment;

wherein the discharge element comprises a duct extending from the opening and a scale collector having walls defining the collection compartment, the scale collector being removably attachable to the duct; and
wherein the scale collector scale collector is insertable into the discharge element in an upward direction compared to a plain formed by the soleplate for closing and sealing the collection compartment and then receiving the calcified deposits therein; wherein the scale collector comprises a lift lever which is configured to be actuated between a locked position and an unlocked position; and wherein the lift lever is configured to be rotated to a horizontal direction in the locked position and to a downward direction in the locked position.

10. A steam iron according to claim 9 , wherein the lift lever comprises a handle and two lever arms, the handle comprises a first latching nib; the scale collector further comprises a main body, the main body comprises a second latching nib; the first latching nib and the second latching nib are configured to form a snap fit in the locked position correspondingly which keeps the lift lever close to the main body.

11. A steam iron according to claim 9 , wherein the lift lever comprises a handle and two lever arms, each lever arm comprises a rotational latch away from the end of the handle; wherein the scale collector further comprises a main body, the main body comprises two door catches sitting at the positions correspond to the positions of the rotational latches; the rotational latches and the door catches are configured to form snap fits in the locked position correspondingly which keeps the lift lever close to the main body.

12. A steam iron according to claim 10 , wherein each lever arm comprises a pivoting mechanism away from the end of the handle, each pivoting mechanism comprises an inner side and an outer side; two first concave parts are set at the inner sides respectively for accommodating two convex parts of the main body for making the lift lever rotatable about a rotational axis; two second concave parts are set at the outer sides respectively for accommodating two cylindrical rods fixed inside the discharge element for making the lift lever synchronously rotatable about the rotational axis on the cylindrical rods; wherein each second concave part comprises a hook shaped portion, each hook shaped portion comprises an open section along its rotational circle; wherein each open section is configured to match with the dimension of the cylindrical rod to render the hook shaped portion to be removable therefrom in the unlocked position and to be blocked against the cylindrical rod in the locked position.

13. A steam iron according to claim 1 , wherein the retaining member extends over at least 5% of a bottom wall of the collection compartment.

14. A steam iron according to claim 1 , wherein the discharge element comprises a passage for carrying the calcified deposits formed in the steam chamber to the collection compartment, wherein the retaining member forms a boundary surface of the passage.
