Abstract:
1. An instant water heating apparatus for a cleaning machine comprising: a housing having a water inlet port, a water outlet port, and a flow path formed between the water inlet port and the water outlet port; a heat exchange part having a heating part for exchanging heat with fluid supplied through the water inlet port and guiding the fluid to the water outlet port; and a mixing part having an introduction port for uniformly mixing fluid of a warm water layer and a cold water layer, when the fluid heat-exchanged in the heat exchange part is guided to the water outlet port in a laminar flow in which temperatures of the fluid are divided as the warm water layer in contact with a heater and the cold water layer not in contact with the heater, wherein the introduction port has a diameter larger than that of the water outlet port so that the mixing part generates countercurrent to sufficiently mix the heat-exchanged fluid.
