Abstract

A garment steamer ( 1 ) comprising a base body ( 10 ) accommodating a liquid water tank ( 26 ); a liquid water pump ( 32 ), having a water inlet ( 32 a ) and a water outlet ( 32 b ), wherein the water inlet ( 32 a ) is fluidly connected to the liquid water tank ( 26 ). The garment steamer also comprises a steam head ( 50 ) that is moveable with respect to the base body ( 10 ) and that accommodates a steam chamber ( 70 ), having a liquid water inlet and a steam outlet, wherein said steam outlet includes at least one steam nozzle ( 76 ); a heating element ( 72 ) that is provided in or adjacent said steam chamber ( 70 ), and configured to evaporate liquid water passing through said steam chamber. A liquid water tube ( 38 b, 38 c ) fluidly interconnects the water outlet ( 32 b ) of the water pump ( 32 ) and the liquid water inlet of the steam chamber ( 70 ) in the steam head ( 50 ).

First claim

The invention claimed is:

1. A garment steamer, comprising:
a base body, the base body comprising:
a liquid water tank;
a liquid water pump, having a water inlet and a water outlet, wherein the water inlet is fluidly connected to the liquid water tank;

a steam head moveable with respect to the base body, the steam head comprising a steam chamber, having a liquid water inlet and a steam outlet, said steam outlet including at least one steam nozzle;
wherein the steam head comprises a housing, said housing defining:
an elongate handle section having a first end and a second end, and configured to be gripped by a hand of a user;
a nozzle head that is provided at the first end of the handle section, said nozzle head including said at least one steam nozzle; and
a steam guard that is directly connected to the steam head including a connecting portion directly connected to the nozzle head and an extending U-shaped portion extending downwardly in a direction perpendicular to the direction of steam released through at least one steam nozzle, the extended U-shaped portion having a width greater than the width of the elongate handle section and positioned in front of a user's hand gripping the elongate handle section so as to protect the user's hand;
the steam head further comprising:
a heating element provided in or adjacent said steam chamber, and configured to evaporate liquid water passing through said steam chamber;
at least one printed circuit board comprising power conversion electronics and a thermostat to power and control the heating element;
a liquid water tube configured to fluidly interconnect the water outlet of the water pump in the base body and the liquid water inlet of the steam chamber in the steam head,
a liquid water flow control valve disposed in one of a fluid connection between the water tank and the water inlet of the water pump and the liquid water tube, wherein a flow rate of the liquid water flow control valve is manually controlled, and
a chemical dispenser that is included in the water tank.

2. The garment steamer according to claim 1 , further comprising a flexible connection cord that interconnects the base body and the steam head, and that accommodates at least a portion of the liquid water tube, said connection cord having an outer diameter smaller than 10 mm.

3. The garment steamer according to claim 1 , wherein the water tank has a volume in the range of 350-750 cubic centimeters.

4. The garment steamer according to claim 1 , wherein the steam head has a dry mass smaller than 800 grams.

5. The garment steamer according to claim 4 , wherein the steam head has a dry mass of 750 grams.

6. The garment steamer according to 1 , further comprising a fastener that is attached to said base body, configured to enable a user to fasten the base body to the user's body.

7. The garment steamer according to claim 1 , wherein the water pump is a diaphragm pump.

8. The garment steamer according to claim 1 , wherein the base body defines a refill opening that provides direct access to the water tank.

9. The garment steamer according to claim 1 , wherein the at least one steam nozzle is encircled by a spacer bracket that prevents a substantially planar object from direct contact with said steam nozzle.

10. The garment steamer according to claim 1 , wherein the steam outlet of the steam chamber is always open.

11. The garment steamer according to claim 1 , wherein the base body does not accommodate a heating element for evaporating liquid water.

12. The garment steamer according to claim 1 , wherein the steam head does not include a liquid water reservoir with a volume larger than 15 cubic centimeters.

13. The garment steamer according to claim 1 , the garment steamer being configurable to:
fill the water tank with water via a refill opening in the water tank;
power and control the heating element to a preset temperature by the power conversion electronics and the thermostat provided on the printed circuit board integrated within the steam head;
activate the pump to draw liquid from the water tank through a tube section to force the liquid through the tube section at a rate determined by the manually controlled liquid water flow control valve to the steam chamber in the steam head,
generate steam in the steam head using the drawn liquid;
release said generated steam through the at least one nozzle of the steam head and
move the steam head along a provided fabric.

14. The garment steamer according to claim 13 , wherein releasing the steam through the at least one nozzle of the garment steamer steam head further comprises: pumping liquid water from the water tank through the liquid water tube to the steam chamber.

15. The garment steamer according to claim 1 , wherein the chemical dispenser is configured to give off at least one chemical to passing water.

16. The garment steamer according to claim 15 , wherein the chemical is one of a fragrance or an additive.

17. The garment steamer according to claim 1 , wherein the base body includes:
a back cover, further including a back wall with a first upstanding wall provided thereon, the first upstanding wall extending partially along and partially within a circumference of the back wall,
a tank cover, including a front wall, and a second upstanding wall extending partially along and partially within a circumference of the front wall,
a top cover,
wherein the first and second upstanding walls are complementary shaped such that when the back cover and the tank cover are slid onto one another, the back wall, front wall and first and second upstanding walls define the liquid water tank.
