Heating appliance
An iron generally includes a water tank and a steam generator in flow communication with the water tank. The steam generator includes a thin-film heater tube that receives water from the water tank to generate steam inside the heater tube.
1. An iron comprising:
a water tank; and
a steam generator in flow communication with the water tank, wherein the steam generator comprises a thin-film heater tube that receives water from the water tank to generate steam inside the heater tube, wherein the steam generator has a relief valve attached to the heater tube, the relief valve configured to release steam back into the water tank in the event of an overpressure condition within the heater tube.
2. The iron of claim 1 wherein the heater tube has a serpentine profile.
3. An iron comprising:
a water tank;
a steam generator in flow communication with the water tank, wherein the steam generator comprises a thin-film heater tube that receives water from the water tank to generate steam inside the heater tube; and
a sole plate unit disposed beneath the water tank in spaced relation to define a chamber in which the steam generator is disposed.
4. The iron of claim 3 wherein the steam generator is configured to release steam into the chamber.
5. The iron of claim 4 wherein the sole plate unit has a plurality of holes for exhausting steam from the chamber.
6. The iron of claim 5 wherein the sole plate unit comprises a thin-film heater plate.
7. The iron of claim 6 wherein the holes extend through the heater plate.
8. The iron of claim 6 further comprising a battery that supplies electrical current to the heater tube and the heater plate.
9. The iron of claim 1 further comprising a battery that supplies electrical current to the heater tube.
10. An iron comprising:
a water tank;
a sole plate unit comprising a sole plate and a thin-film heater plate that heats the sole plate, wherein the sole plate unit has a plurality of holes; and
a plurality of steam generator devices each coupled in flow communication between the water tank and one of the holes of the sole plate unit.
11. The iron of claim 10 wherein each of the steam generator devices is a piezo atomizer device.
12. The iron of claim 10 further comprising a battery that supplies electrical current to the heater plate.
13. The iron of claim 10 wherein the water tank comprises a water tank cover having a plurality of outlet ports each coupled in flow communication with one of the steam generator devices.
14. The iron of claim 10 wherein the holes extend through the heater plate.
15. A cordless iron comprising;
a sole plate;
a thin-film heater plate that heats the sole plate;
a battery that supplies the thin-film heater plate with electrical current; and
a dampening mechanism comprising a biasing element that biases the sole plate away from the heater plate.
16. The cordless iron of claim 15 wherein the dampening mechanism comprises attractive members configured to draw the sole plate toward the heater plate against the bias of the biasing element.
17. The cordless iron of claim 16 wherein the attractive members comprise an electromagnet coupled to one of the sole plate and the heater plate, and a metallic element coupled to the other of the sole plate and the heater plate.
18. A kit comprising the cordless iron of claim 17 wherein the kit includes a docking station that receives the iron and causes the electromagnet to be energized for drawing the sole plate toward the heater plate when the iron is seated on the docking station.
19. The kit of claim 18 wherein the docking station electrically connects the battery to an external power supply for charging the battery when the iron is seated on the docking station.
