Abstract
A dryer and an operation method thereof are useful in a 5G environment provided for the Internet of Things. The dryer includes a heating device, a tumbler having an entrance connected to the heating device, a fan provided connected to the exit of the tumbler, a heat exchanger disposed in a flow line of a working fluid connected to the exit of the fan, a compressor having an entrance connected to a circulation line of the working fluid connected to the exit of the fan and an exit connected to the entrance of the heat exchanger, and a first cleaning unit connected to the entrance of the heat exchanger and to the exit of the heat exchanger.
Claims20
A dryer comprising:
- a heating device;
- a tumbler having an entrance connected to the heating device, the tumbler being configured to receive one or more objects to be dried;
- a fan connected to an exit of the tumbler;
- a heat exchanger connected to an exit of the fan through a flow line, the flow line being configured to carry a working fluid;
- a circulation line connected to the exit of the fan and configured to carry the working fluid;
- a compressor having (i) an entrance connected to the circulation line and (ii) an exit connected to an entrance of the heat exchanger;
- a first reservoir having an entrance connected to an exit of the heat exchanger;
- a first pump having an exit connected to the entrance of the heat exchanger;
- a non-circulation line that connects the compressor to the heat exchanger and is configured to provide the working fluid discharged from the compressor to the heat exchanger;
- and
- a first cleaning line that connects the first reservoir to the first pump, the first cleaning line having (i) a first end connected to the first reservoir and (ii) a second end connected to the non-circulation line,
- wherein the heat exchanger is configured to discharge the working fluid toward the first reservoir after exchanging heat between (i) the working fluid that is provided from the compressor to the heat exchanger through the non-circulation line and has a first temperature and (ii) the working fluid that is in the circulation line and has a second temperature less than the first temperature.
