Abstract

A laundry treating apparatus is provided that may include a laundry accommodation device that provides a space in which laundry is accommodated; a circulation passage provided outside of the laundry accommodation device, and providing a space in which air circulates to an inside of the laundry accommodation device; a heat exchanger provided in the circulation passage; a filter device provided in the circulation passage, that filters foreign materials introduced to the heat exchanger; and a washer provided between the heat exchanger and the filter device, that sprays washing water to each of the heat exchanger and the filter device.

Claims (39)

1. A laundry treating apparatus, comprising:

a laundry accommodation device that provides a space for laundry to be accommodated;

a circulation passage provided outside of the laundry accommodation device, and providing a space in which air circulates to an inside of the laundry accommodation device;

a heat exchanger provided in the circulation passage;

a filter device provided in the circulation passage, that filters foreign materials introduced to the heat exchanger; and

a washer provided between the heat exchanger and the filter device, that sprays washing water onto each of the heat exchanger and the filter device, wherein the filter device includes:

a filter frame provided at the circulation passage; and

a filter provided at the filter frame, that filters foreign materials, wherein the filter frame includes:

a body arranged at an inclination angle from a straight line perpendicular to a bottom surface of the circulation passage;

a guider provided on a lower surface of the body, that guides washing water sprayed by the washer; and

an open surface provided at an end of the guider by which the guider communicates with a discharge duct, and wherein the guider includes an inclined surface provided on a lower surface of the guider and inclined toward the open surface.

2. The laundry treating apparatus of claim 1 , wherein the discharge duct communicates with at least one of a drain device, an exhaust device, or a supply device, which are provided at a tub of the laundry accommodation device.

3. The laundry treating apparatus of claim 1 , wherein the washer includes:

a nozzle body; and

one or more nozzle holes that spray washing water provided at each of both side surfaces of the nozzle body to face the heat exchanger and the filter device.

4. The laundry treating apparatus of claim 3 , wherein the washer further includes a water supply device that supplies washing water into the nozzle body, and wherein the water supply device further includes a divergence pipe that diverts washing water to the one or more nozzle holes that face heat exchanger, and one or more nozzle holes that face the filter device.

5. The laundry treating apparatus of claim 1 , wherein the washer includes:

a heat exchanger washing portion that sprays washing water toward the heat exchanger;

a filter washing portion configured to spray washing water toward the filter device; and

a water supply device that supplies washing water to the washer.

6. The laundry treating apparatus of claim 5 , wherein the water supply device includes:

a first water supply device that supplies washing water to the heat exchanger washing portion; and

a second water supply device that supplies washing water to the filter washing portion.

7. The laundry treating apparatus of claim 6 , wherein the first water supply device and the second water supply device are operated independently.

8. The laundry treating apparatus of claim 1 , wherein the washer includes:

a nozzle body;

one or more nozzle holes that spray washing water provided at each of both side surfaces of the nozzle body to face the heat exchanger and the filter device; and

a water supply device that supplies washing water into the nozzle body.

9. A laundry treating apparatus, comprising:

a laundry accommodation device that provides a space for laundry to be accommodated;

a circulation passage provided outside of the laundry accommodation device, and providing a space in which air circulates to an inside of the laundry accommodation device;

a heat exchanger provided in the circulation passage;

a filter device provided in the circulation passage, that filters foreign materials introduced to the heat exchanger; and

a washer provided in the circulation passage between the heat exchanger and the filter device, that sprays washing water onto each of the heat exchanger and the filter device, wherein the filter device includes:

a filter frame removably provided in the circulation passage; and

a filter provided on the filter frame, that filters foreign materials, wherein the filter frame includes:

a body arranged at an inclination angle from a straight line perpendicular to a bottom surface of the circulation passage;

a guider provided on a lower surface of the body, that guides washing water sprayed by the washer; and

an open surface provided at an end of the guider by which the guider communicates with a discharge duct that communicates with at least one of a drain device, an exhaust device, and a supply device, which are provided at a tub of the laundry accommodation device, and wherein the guider includes an inclined surface provided on a lower surface of the guider and inclined toward the open surface.
