Abstract

A laundry machine includes a body for defining an exterior; a water supply valve provided in the body and connected with an outer water supply; a drum rotatably mounted within the tub; at least one steam generator to supply steam ino the drum; and a water-adjust-valve to adjust the water amount supplied to the steam generator.

First claim

The invention claimed is:

1. A laundry machine comprising:
a first body;
a water supply valve provided at the first body and connected with an outer water supply;
a drum rotatably mounted within the first body, laundry being loaded into the drum;
at least one steam generator to generate steam to be supplied into the drum;
a water regulator to regulate an amount of water supplied per predetermined time from the water supply valve to the steam generator,
wherein the steam generator includes a predetermined water inflow space therein to allow water to flow therein, to generate steam from the flowing water and to supply the steam into the drum; and
a steam supply pipe provided between the steam generator and the drum to supply the steam into the drum,
wherein the steam generator comprises:
a steam generating part having the predetermined water inflow space therein to allow water to flow therein, the steam generating part having a water inlet and an outlet respectively communicating with the water inflow space;
a water inlet path connecting the water supply valve to the water inlet of the steam generating part;
an outlet path connecting the outlet of the steam generating part to the steam supply pipe; and
a heater to heat the flowing water through the inflow space from the water inlet of the steam generating part to the outlet of the steam generating part using the water pressure of the outer water supply to generate steam, and

wherein the steam generated in the steam generator is supplied into the drum without a device for intentionally or selectively blocking the supplied steam.

2. The laundry machine of claim 1 , wherein the water regulator is in a pipe connecting the water supply valve to the steam generator.

3. The laundry machine of claim 1 , wherein the water regulator is a solenoid valve which opens/closes a path receiving water once the power is applied thereto.

4. The laundry machine of claim 3 , wherein the solenoid valve regulates the water amount supplied to the steam generator by periodically repeating the opening/closing operation.

5. The laundry machine of claim 1 , wherein the water regulator comprises:
a second body having an inlet formed at a first side thereof to draw water, an outlet formed at a second side thereof to discharge water and a water through hole formed between the inlet and the outlet; and
a driving part to open/close the water-through hole.

6. The laundry machine of claim 1 , wherein the steam generating part is provided within the first body of the laundry machine so that the outlet may be positioned higher than the water inlet based on a horizon line reference.

7. The laundry machine of claim 1 , wherein the cross section of the steam generating part is larger than the cross section of the water inlet path and of the outlet path.

8. The laundry machine of claim 7 , wherein the cross section of the outlet path is smaller than the cross section of the water inlet path.

9. The laundry machine of claim 1 , wherein the water inlet path comprises
a water supply pipe having a first end thereof connected with the water supply; and
a water inlet pipe having a first end connected with a second end of the water supply pipe and a second end thereof connected with the water inlet of the steam generating part.

10. The laundry machine of claim 9 , wherein the water regulator is in the water supply pipe.

11. The laundry machine of claim 1 , wherein the steam generator further comprises a bypass path to discharge water that overflows from the water inflow space of the steam generating part.

12. The laundry machine of claim 11 , wherein an end of the bypass path is in a water supply pipe portion that is between the water regulator and the water inlet pipe.

13. The laundry machine of claim 1 , wherein the outlet path comprises:
an outlet pipe having a first end thereof connected with the outlet of the steam generating part; and
the steam supply pipe having a first end connected with a second end of the outlet pipe and a second end thereof connected with the drum.

14. The laundry machine of claim 13 , wherein the end of the steam supply pipe that discharges steam is formed in a nozzle shape.

15. A laundry machine comprising:
a first body;
a water supply valve provided at the first body and connected with an outer water supply;
a drum rotatably mounted within the first body, laundry being loaded into the drum;
a hot air supply device to generate and supply hot air into the drum through a drying duct;
at least one steam generator to generate steam to be supplied into the drum, the steam generator including a predetermined water inflow space therein to allow water to flow therein, to generate steam from the flowing water; and
a water regulator to regulate an amount of water supplied per predetermined time from the water supply valve to the water inflow space from the water supply valve,
wherein the steam generator comprises:
a steam generating part having the predetermined water inflow space therein to allow water to flow therein, the steam generating part having a water inlet and an outlet respectively communicating with the water inflow space;
a water inlet path connecting the water supply valve to the water inlet of the steam generating part;
an outlet path connecting the outlet of the steam generating part to the drum; and
a heater to heat the flowing water through the inflow space from the water inlet of the steam generating part to the outlet of the steam generating part using the water pressure of the outer water supply to generate steam.

16. The laundry machine of claim 15 , wherein the steam generated in the steam generator is supplied into the drum through the drying duct.

17. The laundry machine of claim 16 , wherein the steam is supplied into the drum together with the hot air generated by the hot air supplying device.

18. The laundry machine of claim 15 , wherein the water regulator comprises:
a second body having an inlet formed at a first side thereof to draw water therein, an outlet formed at a second side thereof to discharge water and a water-through hole formed between the inlet and the outlet; and
a driving part to open/close the water-through hole.

19. The laundry machine of claim 18 , wherein the water regulator comprises
a coil;
a plunger that moves upwardly to open the water-through hole when power is applied to the coil;
a cylinder to guide the upward/downward movement of the plunger; and
a compressing spring to provide restitution force to the plunger.

20. A laundry machine comprising:
a body;
a drum rotatably mounted within the body, laundry being loaded into the drum;
a water supply valve;
at least one steam generator to generate steam to be supplied into the drum, the steam generator including a predetermined water inflow space therein to allow water to flow therein, to generate steam from the flowing water;
a water regulator to adjust water from the water supply valve to be regularly supplied into the water inflow space without deviation according to the time basis;
a heater which heats water flowing through the water inflow space to generate steam; and
a bypass path to discharge water that overflows from the water inflow space, wherein an end of the bypass path is in a water supply pipe portion that is between the water regulator and a water inlet pipe of the steam generator,
wherein the steam generator comprises:
a steam generating part having the predetermined water inflow space therein to allow water to flow
