Abstract

The present invention relates to a dryer having a liquid spraying function, and according to one aspect of the present invention, a laundry treating apparatus including a plurality of laundry treating courses which have different laundry treating methods is provided. The apparatus comprises: a drum for receiving the laundry; a hot air supply means for supplying hot air to the inner side of the drum; a spraying means for spraying a fragrant solution to the inside of the drum; a manipulating means including a course selecting means for selecting the laundry treating courses; and a controller for controlling the apparatus according to the instructions inputted by the manipulating means, wherein a plurality of laundry treating courses includes at least one scent spray course for spraying the fragrant solution during the laundry treating process, and the course selecting means comprises a scent spray course selecting means for selecting one of the scent spray courses.

First claim

The invention claimed is:

1. A laundry treating apparatus having a plurality of laundry treating courses with different laundry treating methods, the apparatus comprising:
a drum to accommodate laundry;
a hot air supply means to supply hot air to an inner side of the drum, the hot air supply means comprising:
a suction duct to transfer air to the drum, and
a heater provided in the suction duct to heat the air;

a nozzle to spray a fragrant solution into an inner portion of the drum;
a manipulating panel comprising a course selection means configured to select one of the plurality of the laundry treating courses and a scent spraying cancellation button; and
a controller to control the apparatus according to an instruction inputted by the manipulating panel,
wherein the plurality of laundry treating courses comprises at least one scent spray course for spraying the fragrant solution during the laundry treating process,
wherein the course selection means comprises a scent spray course selection means for selecting one of a plurality of scent spray courses,
wherein the manipulating panel comprises a light-emitting element, adjacent the scent spray course selection means, to distinguish the scent spray course selection means from the other course selection means,
wherein the controller is configured to control the apparatus such that a fragrant solution spraying process is not carried out while performing a laundry treating course selected by the course selection means when the scent spraying cancellation button is selected, and
wherein the scent spraying cancellation button is deactivated when a course selected by the course selection means does not include a scent spraying process.

2. A laundry treating apparatus having a plurality of laundry treating courses with different laundry treating methods, the apparatus comprising:
a drum to accommodate the laundry;
a nozzle to selectively spray a fragrant solution or water into an inner portion of the drum;
a manipulating panel comprising a course selection means to select one of the plurality of the laundry treating courses, a medium selection means configured to set a kind of liquid to be sprayed, and a scent spraying cancellation button, and
a controller to control the apparatus according to an instruction inputted by the manipulating panel,
wherein the plurality of laundry treating courses comprises a plurality of liquid spray courses for spraying at least one of the fragrant solution and water during the laundry treating process,
wherein the course selection means is configured to select one of the liquid spray courses,
wherein the controller is configured to control the apparatus such that a fragrant solution spraying process is not carried out while performing a laundry treating course selected by the course selection means when the scent spraying cancellation button is selected, and
wherein the scent spraying cancellation button is deactivated when a course selected by the course selection means does not include a scent spraying process or water is selected by the medium selection means.

3. The apparatus of claim 2 , wherein a course that sprays liquid not selected by the medium selection means is deactivated from selection by the course selection means.

4. The apparatus of claim 2 , wherein the course selection means is configured to sequentially select from a plurality of liquid spray courses including at least one fragrant solution spray course and a water spray course, and at least one other course is sequentially available between the at least one fragrant solution spray course and the water spray course.

5. The apparatus of claim 2 , wherein the manipulating panel further comprises a scent strength adjustment button, and the controller is configured to control the apparatus such that a scent strength is adjusted according to the scent strength adjustment button.

6. The apparatus of claim 5 , wherein the scent strength adjustment button is deactivated when a course selected by the course selection means does not include a scent spraying process or water is selected by the medium selection means.

7. The apparatus of claim 6 , wherein the manipulating panel further comprises a plurality of light-emitting elements capable of visually displaying whether the scent strength adjustment button is activated or not.

8. The apparatus of claim 2 , further comprising:
a medium recognition means to measure a level of voltage drop due to a resistance of the liquid so as to recognize a kind of the liquid,
wherein the course selection means comprises a liquid spray course selection means for selecting one of the plurality of liquid spray courses.

9. The apparatus of claim 8 , wherein the controller recognizes a kind of liquid stored in a storage container by the medium recognition means, and deactivates a liquid spray course selection means corresponding to a course for spraying a liquid different from the liquid stored in the storage container.

10. The apparatus of claim 8 , wherein the medium recognition means comprises an electrode sensor having a pair of electrodes being brought into contact with the liquid.
