1. A clothes treatment apparatus comprising:
a cabinet;
a treatment chamber disposed within the cabinet and configured to receive hung clothes;
a cycle chamber disposed within the cabinet and below the treatment chamber;
a tank module frame disposed forward of the cycle chamber;
a steam unit disposed within the cycle chamber and configured to supply steam to the treatment chamber;
a heat pump unit disposed within the cycle chamber and configured to condition and circulate air in the treatment chamber;
a water supply tank that is mounted separably on the tank module frame, that is configured to be in fluid communication with the steam unit based on the water supply tank being mounted on the tank module frame, and that is configured to store water to generate steam for performing a plurality of cycles of the clothes treatment apparatus, the water supply tank being configured to supply the water to the steam unit;
a first float case disposed at a rear side of the water supply tank, wherein an upper portion of the first float case is positioned at a level of water that generates steam for one cycle of the clothes treatment apparatus;
a first float disposed within the first float case and configured to move up and down by buoyancy; and
a first detecting sensor disposed at the tank module frame, the first detecting sensor facing the rear side of the water supply tank and the first float case,
wherein the first detecting sensor is configured to, based on the first float being positioned at a bottom of the first float case, not sense the first float,
wherein the first detecting sensor is configured to, based on the first float being positioned at the upper portion of the first float case, sense the first float,
wherein, based on (i) the water supply tank not being mounted on the tank module frame or (ii) the first float being positioned below a detecting level at which the first detecting sensor can sense the first float in response to a decrease in water stored in the water supply tank, the first detecting sensor cannot sense the first float, and the clothes treatment apparatus is configured to output a water deficiency signal, and
wherein the clothes treatment apparatus is configured to:
based on a user manipulating the clothes treatment apparatus in a state in which the water deficiency signal is output, not start a cycle of the clothes treatment apparatus, and
based on outputting the water deficiency signal while supplying steam to perform a cycle of the clothes treatment apparatus, continue to complete the cycle that is currently being performed.
