Abstract

Provided is a clothes treating apparatus. The clothes treating apparatus may include a clothes receiving device providing a space for receiving clothes therein, a circulation passage provided in the clothes receiving device and configured to provide a flow path for air circulation through the clothes receiving device, and a heat-exchanging device provided in the circulation passage and configured to dehumidify air introduced into the circulation passage. A blower may be provided in the circulation passage and configured to circulate air within the clothes receiving device. A condensed water discharge device may be provided at a lower surface of the circulation passage and configured to discharge condensed water generated by the heat-exchanging device. The condensed water discharge device may include a backflow-preventing member that prevents backflow of the condensed water from the condensed water discharge device to the circulation passage.

First claim

What is claimed is:

1. A clothes treating apparatus comprising:
a clothes receiving device providing a space for receiving clothes therein;
a circulation passage provided in the clothes receiving device and configured to provide a flow path for air circulation through the clothes receiving device;
a heat-exchanging device provided in the circulation passage and configured to dehumidify air introduced into the circulation passage;
a blower provided in the circulation passage and configured to circulate air within the clothes receiving device; and
a condensed water discharge device provided at a lower surface of the circulation passage and configured to discharge condensed water generated by the heat-exchanging device,
wherein the condensed water discharge device includes a backflow-preventing member that prevents backflow of the condensed water from the condensed water discharge device to the circulation passage,
wherein the clothes receiving device includes a drum, and the heat-exchanging device is provided over the drum inside a cabinet of the clothes treating apparatus, and
wherein the backflow-preventing member is provided over the drum between the heat exchanging device and the drum.

2. A clothes treating apparatus comprising:
a clothes receiving device that includes a drum;
a heat-exchanging device provided over the drum;
a circulation passage to provide a flow path for air circulation between the drum and the heat-exchanging device;
a blower provided in the circulation passage and configured to generate airflow within the circulation passage; and
a condensed water discharge device coupled to the circulation passage,
wherein the heat-exchanging device is positioned inside the circulation passage and configured to dehumidify air, and the circulation passage includes a lower surface positioned under the heat-exchanging device to collect condensed water from the heat-exchanging device,
wherein the condensed water discharge device is connected to the lower surface of the circulation passage to discharge the collected condensed water, and
wherein the condensed water discharge device includes a backflow-preventing member that prevents backflow of the condensed water from the condensed water discharge device to the circulation passage,
wherein the backflow-preventing member is a discharge pipe having an upper section connected to the lower surface of the circulation passage and a lower section that extends downward from the upper section,
wherein the upper section is inclined at a prescribed angle to extend downward from the circulation passage and the lower section is angled relative to the upper section to extend down toward a bottom of the clothes treating apparatus.

3. The apparatus of claim 2 , wherein the lower section extends linearly downward from the upper section and includes
a first portion having a first width,
a second portion having a second width narrower than the first width of the first portion, and
a bottleneck portion that extends downward from the first portion to the second portion, a width of the bottleneck portion decreasing gradually from the first portion to the second portion such that condensed water accumulates above the bottleneck portion inside the discharge pipe.

4. A clothes treating apparatus comprising:
a clothes receiving device providing a space for receiving clothes therein;
a circulation passage provided in the clothes receiving device and configured to provide a flow path for air circulation through the clothes receiving device;
a heat-exchanging device provided in the circulation passage and configured to dehumidify air introduced into the circulation passage;
a blower provided in the circulation passage and configured to circulate air within the clothes receiving device; and
a condensed water discharge device provided at a lower surface of the circulation passage and configured to discharge condensed water generated by the heat-exchanging device,
wherein the condensed water discharge device includes a backflow-preventing member that prevents backflow of the condensed water from the condensed water discharge device to the circulation passage,
wherein the backflow-preventing member is a discharge pipe having an upper section connected to the lower surface of the circulation passage and a lower section that extends downward from the upper section,
wherein the upper section is inclined at a prescribed angle to extend downward from the circulation passage and the lower section of the discharge pipe is angled relative to the upper section to extend down toward a bottom of the clothes treating apparatus,
wherein the lower section of the discharge pipe includes
a first portion having a first width,
a second portion having a second width narrower than the first width of the first portion, and
a bottleneck portion that extends downward from the first portion to the second portion,
wherein the first width of the first portion and the second width of the second portion in the lower section of the discharge pipe is configured such that condensed water is accumulated above the second portion to prevent backflow of gas and condensed water into the circulation passage.

5. The apparatus of claim 4 , wherein the bottleneck portion has an upper end having the first width of the first portion and a lower end having the second width of the second portion, a width of the bottleneck portion decreasing gradually from the first portion to the second portion.

6. The apparatus of claim 4 , wherein a distance between the bottleneck portion and the lower surface of the circulation passage is at least 120 mm.

7. The apparatus of claim 4 , wherein the condensed water discharge device is positioned under the circulation passage, and the lower surface of the circulation passage is inclined to direct flow of condensed water to the condensed water discharge device.
