According to the embodiment of the present invention, the internal structure of the boiler can be simplified by integrally joining the multi-way valve to the hot water heat exchanger.
In addition, it is easy to disassemble the hot water heat exchanger and the multi-chamber valve in the boiler, so that it becomes easy to replace when the hot water heat exchanger and the multi-chamber valve fail.
In addition, the multi-way valve can simplify the piping connection structure by integrally forming the heating water feeding inlet, the heating water feeding outlet, the low temperature milk feeding outlet, the direct water inlet, and the hot water outlet.
Also, the pressure loss of the heating water flowing inside the multi-way valve during the heating operation and the hot water operation is reduced.
Further, since the positions of the inlet and outlet through which the multi-directional valve flows are provided on the same plane, the replacement operation of the multi-directional valve is facilitated.
