Abstract

A domestic appliance, such as a steam iron or a coffee making apparatus comprises a housing, a water reservoir, an actuator, and a boiler for providing hot water or steam for use by the appliance. In operation, a plunger pump of the actuator is reciprocating at the mains frequency, which introduces vibrations. To reduce undesired sound and noise from the vibrations, the domestic appliance further comprises a sub frame and a base frame, wherein the actuator is mounted on the sub frame and a resilient member is arranged between the sub frame and the base frame for moveably mounting the sub frame at the base frame.

First claim

The invention claimed is:

1. A domestic appliance comprising:
a base frame;
an actuator provided with a drive member and arranged for reciprocating movement of the drive member;
a rigid sub frame, wherein the actuator is mounted on the rigid sub frame; and
a resilient member that comprises at least one elastomer mount arranged between the rigid sub frame and the base frame for moveably mounting the rigid sub frame at the base frame, wherein an interior portion of the at least one elastomer mount is constructed and arranged to allow both (i) deflection in an x,y direction for lateral movement of the rigid sub frame in a plane parallel to the base frame and (ii) rotation in a plane of the rigid sub frame for rotation of the rigid sub frame around an axis of rotation transverse to the plane of the base frame, wherein the at least one elastomer mount further comprises a disc shaped elastomer mount and the interior portion comprises the disc shaped elastomer mount with a portion of material removed from an interior of the disc shaped elastomer mount of a length L, between a first point of the elastomer mount where the elastomer mount rests on the base frame and a second point of the elastomer mount where on the rigid sub frame rests, and in which a distance d along a horizontal cross-section, between a side of the elastomer mount and the base frame, is sufficiently large, together with length L, allows both (i) the deflection of the disc shaped elastomer mount in the x,y direction and (ii) the rotation of the disc shaped elastomer mount in the plane of the rigid sub frame.

2. The domestic appliance according to claim 1 , wherein the axis of rotation is through a center of gravity of a mass and shape of the rigid sub frame and the actuator.

3. The domestic appliance according to claim 1 , wherein the domestic appliance further comprises a boiler or a flow-through heater for water heating or steam generation mounted at the rigid sub frame.

4. The domestic appliance according to claim 3 , wherein the actuator is operationally connected to the boiler or the flow-through heater via a pressure resistant tube.

5. The domestic appliance according to claim 1 , wherein the domestic appliance further comprises a water reservoir provided at the rigid sub frame, the water reservoir being in fluid communication with the actuator via a flexible tube.

6. The domestic appliance according to claim 5 , wherein the water reservoir is detachably mounted to the rigid sub frame.

7. The domestic appliance according to 7 , wherein the flexible tube comprises a corrugated tube.

8. The domestic appliance according to claim 1 , wherein the actuator comprises a plunger pump or a diaphragm pump.

9. The domestic appliance according to claim 1 , wherein the disc shaped elastomer mount is adapted to be mounted via a connecting member in a center of the disc shaped elastomer mount to the base frame, and further wherein the length L determines a maximum swing of the interior portion and a horizontal movement related to the swing of the sub frame with respect to the base frame.

10. The domestic appliance according to claim 9 , further wherein the disc shaped elastomer mount is further provided with a cap overlying a portion of the disc shaped elastomer mount, wherein the cap is adapted to prevent the connecting member from pushing through the disc shaped elastomer mount due to forces exerted on the disc shaped elastomer mount.
