Abstract

The clothing dryer includes a filter device to filter foreign matter in a flow channel along which high-temperature, high-humidity air having dried an object to be dried is discharged. The filter device is mounted so as to be moved inward into and outward from a cabinet in a horizontal state. Usability and reliability of the clothing dryer are improved.

First claim

What is claimed is:

1. A clothing dryer comprising:
a cabinet having a front frame at which an introduction port is formed;
a drying drum rotatably mounted in the cabinet;
a filter device to filter foreign matter in a flow channel along which air having dried an object to be dried in the drying drum is discharged by suction force of a fan; and
a filter mounting part formed at one side of the front frame so that the filter device is mounted in the filter mounting part,
wherein the filter device comprises a front cover to cover the filter mounting part, and the front cover comprises a front part forming a front surface of the cabinet,
and a door contact part configured to come into contact with one side of a rear of the door and recessed rearward from the front part corresponding to a rearmost portion of the door.

2. The clothing dryer according to claim 1 , wherein the filter device comprises a box type filter mounted in the flow channel to filter out the foreign matter, and the filter device is mounted so as to be moved inward into and outward from the filter mounting part in a horizontal state.

3. The clothing dryer according to claim 2 , wherein the filter device further comprises a filter location frame extending from a rear of the front cover so that the filter is located in the filter location frame.

4. The clothing dryer according to claim 2 , further comprising:
a door to open and close the introduction port, wherein
the filter mounting part is disposed adjacent to a lower side portion of the introduction port, and
the front cover further comprises a depression part corresponding to a lower side portion of the door.

5. The clothing dryer according to claim 3 , wherein the filter is detachably mounted in the filter location frame, and the filter is made of woolen fabric, PET, or steel.

6. The clothing dryer according to claim 1 , further comprising:
a fan mounted in the flow channel to generate suction force to suction air in the drying drum and a filter duct mounted in the flow channel upstream of the fan, wherein
the filter duct is provided with a filter insertion port formed in a shape corresponding to the filter so that the filter is inserted into the filter duct through the filter insertion port.

7. The clothing dryer according to claim 6 , wherein the filter duct comprises an inlet communicating with the drying drum and an outlet communicating with the flow channel in which the fan is mounted, the inlet being provided with a net type filter grill.

8. A clothing dryer comprising:
a cabinet having a front frame at which an introduction port is formed;
a door rotatably mounted at the front frame to open and close the introduction port;
a drying drum rotatably mounted in the cabinet;
a filter duct disposed adjacent to a rear of the front frame to form a portion of a flow channel along which air having dried clothing in the drying drum is discharged; and
a filter device detachably mounted in the filter duct so that the filter device is moved inward into and outward from the cabinet in a horizontal state to filter foreign matter from air introduced into the filter duct,
wherein the filter device comprises a filter case forming a portion of the front frame, and
the filter case includes a front part forming a front surface of the cabinet, and a door contact part recessed rearward from the front part corresponding to a rearmost portion of the door.

9. The clothing dryer according to claim 8 , wherein the clothing dryer is an exhaust type clothing dryer or a condensing type clothing dryer having a circulation channel.

10. The clothing dryer according to claim 8 , wherein the filter device further comprises a filter mounted in the flow channel of the filter duct, and
the filter is detachably mounted at the filter case.

11. The clothing dryer according to claim 10 , wherein the filter duct has a filter insertion port through which the filter is inserted into the flow channel of the filter duct.

12. The clothing dryer according to claim 11 , wherein the filter duct comprises an inlet communicating with the drying drum and an outlet communicating with a blowing case having a fan mounted therein to generate suction force in the drying drum, and
the inlet is provided with a net type filter grill.

13. The clothing dryer according to claim 11 , wherein the front frame is provided with a filter mounting part in which the filter case is mounted and supported, and
the filter case comprises a front cover to cover the filter mounting part and a filter location frame in which the filter is located, the filter location frame being mounted in the filter duct.

14. The clothing dryer according to claim 13 , wherein the front cover is disposed adjacent to a lower side of the door, and the front cover is provided with a depression part corresponding to a lower end portion of the door.

15. The clothing dryer according to claim 14 , wherein the depression part is provided with a depressed grip part configured to be held by a user.

16. The clothing dryer according to claim 13 , wherein the filter comprises a quadrangular filter frame located and supported in the filter location frame and a filter net mounted inside the filter frame to filter out foreign matter, the filter net being formed in a shape of a box opened at a top thereof.

17. The clothing dryer according to claim 16 , wherein the filter net is made of woolen fabric, polyethylene terephthalate (PET), or steel.

18. The clothing dryer according to claim 14 , wherein the filter duct is disposed adjacent to a lower side of the introduction port.

19. The clothing dryer according to claim 14 , further comprising:
a front support plate to rotatably support a front end of the drying drum, the front support plate having an opening corresponding to the introduction port, wherein
the filter duct is disposed between the front frame and the front support plate.

20. The clothing dryer according to claim 13 , wherein the front cover is provided with the door contact part configured to come into tight contact with one side of a rear of the door when the filter device is mounted at the cabinet.
