Abstract

A laundry machine including a tub in which wash water is stored and/or a drum in which laundry is accommodated, the drum being rotatably provided, a duct configured to communicate with the tub and/or drum, a heater installed in the duct and heating only a predetermined space within the duct, a nozzle installed in the duct and serving to directly supply water to the heated predetermined space, and a blower installed in the duct and serving to blow air toward the predetermined space so as to supply the generated steam into the tub or drum.

Claims (31)

1. A laundry machine comprising:

a tub to store wash water and/or a rotatable drum to accommodate laundry;

a duct in communication with the tub and/or drum;

a heater installed in the duct, the heater occupying a partial space within the duct to create a high temperature environment for steam generation;

at least one nozzle installed in the duct to supply water to the heated heater for generating steam;

a blower installed in the duct, the blower to generate an air flow within the duct and to supply the generated steam into the tub and/or drum,

wherein the at least one nozzle is oriented toward the heater and configured to directly eject water to the heated heater by ejection pressure thereof without actuation of the blower in approximately the same direction as the direction of air flow, and

wherein the heater is spaced apart from the bottom of the duct by a predetermined distance for contacting an amount of air while achieving smooth air flow; and

a recess formed in the a lower region of the duct to collect a remaining water,

wherein the recess is located below the heater.

2. The laundry machine of claim 1 , wherein the nozzle is provided between the heater and the blower.

3. The laundry machine of claim 2 , wherein the nozzle is spaced apart from the heater by a predetermined distance so as to be located close to the blower.

4. The laundry machine of claim 2 , wherein the nozzle is installed close to a discharge portion through which air having passed through the blower is discharged.

5. The laundry machine of claim 1 , wherein the heater is located at one longitudinal side of the duct, and the blower is located at the other longitudinal side of the duct, and the nozzle is located between the heater and the blower.

6. The laundry machine of claim 1 , wherein the nozzle is installed in a blower housing surrounding the blower.

7. The laundry machine of claim 6 , wherein the blower housing includes an upper housing and a lower housing, and the nozzle is installed in the upper housing.

8. The laundry machine of claim 7 , wherein the upper housing has an aperture into which the nozzle is inserted.

9. The laundry machine of claim 8 , wherein the nozzle includes a body and a head.

10. The laundry machine of claim 9 , wherein the head is inserted into the aperture and is located within the duct.

11. The laundry machine of claim 1 , wherein the at least one nozzle includes a plurality of nozzles.

12. The laundry machine of claim 11 , wherein each of the plurality of nozzles includes a body and a head, and the plurality of nozzles are connected to one another via a flange.

13. The laundry machine of claim 12 , wherein the flange has a fastening hole facilitating connection to the duct.

14. The laundry machine of claim 1 , wherein the nozzle directly ejects mist to the heater.

15. The laundry machine of claim 1 , wherein the nozzle includes a spirally extending flow-path therein.

16. The laundry machine of claim 1 , wherein at least a portion of the heater has a bent portion that is bent downward toward the recess.

17. The laundry machine of claim 16 , wherein the bent portion is located in the recess.

18. The laundry machine of claim 1 , further comprising:

a thermal conductive member coupled to the heater to transfer heat of the heater.

19. The laundry machine of claim 18 , wherein at least a portion of the thermal conductive member is located in the recess.

20. The laundry machine of claim 18 , wherein the thermal conductive member includes a heat sink mounted to the heater, at least a portion of the heat sink being located in the recess.

21. The laundry machine of claim 1 , wherein the recess is located below a free end of the heater.
