초록 ▼

A drum washing machine and a clothes dryer equipped with a thermoelectric module are disclosed. The thermoelectric module includes a heat absorption side and a heat dissipation side which absorbs and dissipates heat at a junction between two dissimilar metals depending on direction of current flow through the junction. The heat absorption side is disposed at a hot air flowing passage. Accordingly, the drying apparatus can increase energy efficiency with minor structural modification and becomes environmentally friendly unlike a conventional drying apparatus using a heat pump.

대표청구항 ▼

What is claimed is: 1. A clothes dryer comprising: a drum into which objects to be dried are put; a circulation duct which forms an air circulation passage so that air exhausted from the drum flows again into the drum; a condenser which condenses the air exhausted from the drum, the condenser comprising a thermoelectric module having a heat absorption side and a heat dissipation side which absorbs and dissipates heat at a junction between two dissimilar metals depending on a direction of current flow through the junction, and the condenser is mounted so that the air exhausted from the drum passes by the heat absorption side of the thermoelectric module; a heater which heats the air; a circulation fan which forcedly circulates the air through the circulation duct; an outdoor air-discharge duct which is connected to the condenser to discharge the outdoor air passing by the heat dissipation sides of the condenser; and a guide duct which is connected to the outdoor-discharge duct to bypass a portion of the outdoor air discharged through the outdoor-discharge duct toward the heater. 2. The clothes dryer according to claim 1, wherein the air passing by the heat absorption side flows into the drum via the heat dissipation side of the thermoelectric module. 3. The clothes dryer according to claim 1, wherein the thermoelectric module comprises a plurality of thermoelectric modules which are arranged in a multi-layer structure with a gap therebetween, and wherein the thermoelectric modules respectively include at least one pair of heat absorption sides which oppose each other. 4. The clothes dryer according to claim 3, wherein the air passing by a space between the heat absorption sides flows into the drum via heat dissipation sides of the thermoelectric modules. 5. The clothes dryer according to claim 1, further comprising: an outdoor air-supply duct which is connected to the condenser to supply outdoor air so that the outdoor air passes by the heat dissipation side of the condenser; a cooling fan which is mounted on the outdoor air-supply duct or the outdoor air-discharge duct to suck and discharge the outdoor air; and a variable speed motor which drives the cooling fan. 6. The clothes dryer according to claim 1, wherein the heater is capable of changing a heat release rate. 7. The clothes dryer according to claim 2, wherein the heater is capable of changing a heat release rate. 8. The clothes dryer according to claim 3, wherein the heater is capable of changing a heat release rate. 9. The clothes dryer according to claim 4, wherein the heater is capable of changing a heat release rate. 10. The clothes dryer according to claim 5, wherein the heater is capable of changing a heat release rate.
