A clothes care apparatus may include a cabinet, a first chamber formed inside the cabinet and configured to accommodate clothes, a first door configured to open or close the first chamber, the first door having a second chamber and configured to accommodate clothes, a second door configured to open or close the second chamber and rotatably coupled to the first door, and a spot cleaner disposed inside the second chamber and configured to spot clean the clothes accommodated in the second chamber. The spot cleaner is movable inside the second chamber to spot clean a target area of the clothes accommodated in the second chamber.

The present disclosure provides a drying chamber (condenser) including a container having a steam intake opening, the condenser liquefying steam taken from the steam intake opening into the container, and the drying chamber including a cooling pipe which is disposed in the container and through which coolant circulates.

Provided is a compression system including a compressor configured to compress and discharge a refrigerant and comprising a refrigerant inflow port through which the refrigerant flows in and an oil recovery port for recovering oil, a plurality of oil separator configured to separate the oil which is included in the refrigerant discharged from the compressor and comprising a first oil separator into which the refrigerant discharged from the compressor flows and a second oil separator connected to the first oil separator in series along a travelling path of the refrigerant, a first recovery pipe configured to recover the oil from the first oil separator to the oil recovery port, and a second recovery pipe configured to recover the oil from the second oil separator to the refrigerant inflow port.

An ionic oxidation refreshing system for refreshing an odorized item, comprising an enclosure with an airflow system to contact the odorized item on all sides; an ionization system that produces a positively charged ionized ozone gas mixture inside of the enclosure, killing germs, including odor-causing bacteria, viruses, molds, and fungus, and provides the odorized item inside the enclosure with a net positive charge; a filter that neutralizes and filters out any toxic by-products; an electrostatic liquid atomization system that creates a fine mist of a quick-cleaning solution, and, in conjunction with the airflow system, causes solution droplets to penetrate deep into the odorized item and agitate a surface of the odorized item, ensuring the formula is evenly delivered onto the odorized item without over saturating any area.

Provided is a compression system including, in order to minimize an amount of oil mixed with a supplied refrigerant, a compressor configured to compress and discharge the refrigerant, a plurality of oil separators configured to separate the oil included in the refrigerant discharged from the compressor, and a refrigerant pipe configured to connect the compressor and the plurality of oil separators to form a travelling path of the refrigerant, and the plurality of oil separators are connected in series along the travelling path of the refrigerant.

A laundry treating apparatus includes a 2-tank structure including a distillation tank and a washing tub. The laundry treating apparatus includes the washing tub that defines an inner space configured to receive laundry, the distillation tank configured to store liquid carbon dioxide, a compressor configured to receive gaseous carbon dioxide evaporated from the liquid carbon dioxide in the distillation tank, the compressor being configured to discharge the gaseous carbon dioxide, a cooler configured to cool the gaseous carbon dioxide discharged from the compressor and to supply the liquid carbon dioxide to the washing tub, and a controller configured to perform a control method. In some cases, a laundry treating apparatus includes a 3-tank structure including a storage tank, a washing tub, and a distillation tank.
