Condenser and cleaning device

A cleaning device comprising a cleaning chamber and a condenser, the condenser including a container having a steam intake opening, the condenser liquefying steam received from the steam intake opening into the container, the condenser comprising:

• a first flat surface portion facing the steam intake opening,
• a second flat surface portion provided with the steam intake opening and disposed parallel to the first flat surface portion,
• a cooling pipe disposed in the container and through which coolant circulates,
• wherein the container has a dual-shell structure in which the coolant can circulate,
• wherein the cooling pipe is wound in a spiral to form a central opening, and the cooling pipe is disposed so that the central opening formed by the cooling pipe is aligned with the steam intake opening,
• wherein a plurality of fins extend in a vertical direction and are disposed at predetermined intervals in the vertical direction and in a horizontal direction on the first flat surface portion;
• a door and an opening through which articles to be cleaned are inserted and removed from the cleaning chamber;
• a steam generating unit which generates steam for cleaning in the cleaning chamber;
• a vacuum pump coupled to the cleaning chamber and which reduces pressure in the cleaning chamber;
• and
• wherein the condenser is coupled to the cleaning chamber such that steam used for cleaning in the cleaning chamber is then fed to the condenser.

• wherein a plurality of fins extend in a vertical direction and are disposed at predetermined intervals in the vertical direction and in a horizontal direction on the first flat surface portion;
• wherein steam entering the container by the steam intake opening is condensed by contact with the cooling pipe and contact with the plurality of fins;
• and
• the condenser further including a drain communicating with inside of the container which drains condensed liquid from inside of the container;
• the condenser further including:
• a coolant collection pipe nozzle through which coolant exits the cooling pipe;
• a coolant drainage port through which coolant exits from between walls of the dual-shell structure;
• a vacuum pump;
• and
• a discharge port which communicates inside of the container with the vacuum pump such that the vacuum pump reduces pressure inside of the container.
