Water purifier

A water purifier includes a water supply tube into which water is introduced, a filter member purifying water passing through the water supply tube, a water discharge tube supplying water to the outside of the water purifier, a hot water tube branched from the water discharge tube, a hot water module including a hot water tank provided on the hot water tube to accommodate purified water and a heat generation unit heating the water accommodated in the hot water tank, a controller spaced apart from the hot water tank or the heat generation unit to control the heat generation unit, and a water discharge nozzle supplying the water passing through the water discharge tube and the hot water tube to the outside of the water purifier. At least a portion of the hot water tube or the water discharge tube passes through the controller and is heat-exchanged with the controller.
