1. A laundry processing apparatus comprising:
a cabinet that defines an installation space therein;
a heat exchanger disposed in the installation space of the cabinet and configured to transfer heat of exhaust air generated from a heat-processing of laundry, the heat exchanger having a front surface configured to receive the exhaust air; and
a washing unit that is disposed inside the installation space of the cabinet, that is disposed at an upper portion of the heat exchanger, and that is configured to spray washing water to the front surface of the heat exchanger,
wherein the washing unit comprises:
a water tube configured to supply the washing water toward the heat exchanger,
a nozzle part that is disposed at the upper portion of the heat exchanger, that extends in an inclined direction with respect to an upper surface of the heat exchanger, and that is configured to guide the washing water toward the heat exchanger, the nozzle part having a first side connected to the water tube and a second side that extends toward the front surface of the heat exchanger,
a front guide part spaced apart from the nozzle part, the front guide part comprising a protruding end that extends toward the front surface of the heat exchanger and is configured to guide the washing water discharged from the nozzle part toward the front surface of the heat exchanger, wherein the front surface of the heat exchanger is disposed between the front guide part and the nozzle part, and
a front guide end protruding from the front guide part and having an end protruding to a position lower than an upper surface of the heat exchanger.
